How China became Chinese Essay

Jared’s Diamond’s â€Å"Guns, Germ and Steel† is an historical narrative that focuses on alternate explanations to the rise and fall of civilizations and the development of cultures and societies by tracing evolutions and nuances in world and human history dating as far back as 13,000 years ago to the present. It is an historical treatise that moves away from a largely Eurocentric model of the world towards a more objective analysis of the various environmental, biological, political and economic phenomena surrounding a continent’s growth. The book attempts to unravel the varying fundamental and decisive causations to explain and answer why continents developed differently from each other. For instance, Chapter 16 of the book lays down the conundrum how China became Chinese today—what with its monolithic ethnicity and almost unified language and uniform racial identities, as opposed to its European and North American counterparts: Both of which are characterized by diverse cultures, language and races. Accordingly, China is the way it is now because of several penultimate causations. Foremost of these reasons is that they gained a decided head-start advantage in terms of food production and animal domestication because of its strategic geographic location. There is the Yellow River in the north and the Yangtze River in the south which conveniently cut across the whole span of the continent thereby making trade and production much easier (331). Because of the advances in food production and animal domestication techniques compared to its backwards hunting-gathering neighbours at that time, ethnic north and south Chinese were able to dominate the entire socio-cultural landscape. As early as 7,500 BC, Jared Diamond notes that based on the archaeological pieces of evidence found scattered in the East Asian regions, it would be fair to conclude that â€Å"China was one of the world’s first centres of plant and animal domestication† (229). These valuable crops and animals contributed to the growth of Chinese civilizations especially in terms of population, language and political and social structures because they jumpstart the economy of a given locality. Diamond continues that â€Å"as elsewhere in the world, in China food production gradually led to other hallmarks of civilization† (330). The Chinese began to invent and discover the process of bronze metallurgy and its uses as substitute domestic tools and probably even in warfare. Furthermore, apart from the optimization of the post-Neolithic metal tools technology, the millennia that followed â€Å"saw the outpouring of Chinese technological inventions that included paper, the compass, the wheelbarrow and gunpowder† (ibid. ). These are manifest indications or signs that the Chinese society has undergone a gradual yet upending process of unification or otherwise known as the great Sinification over the years that it had started to develop and took advantage of their valuable food and animal resources. The most interesting part of Diamond’s analysis however has something to do with the correlation he makes with food production and its residual yet significant consequences as with the spread of infectious diseases (ibid. ). Since pigs, according to Diamond, were domesticated so early and became so important in the region, Influenza must have likely have risen in China (ibid. ). Nevertheless, suffice it to say that China is the solid and monolithic China of today because of the advantages in its geographic locations and the kind of culture that was nourished through time because of trade, domination, ethnic assimilation and language unification as also added consequences of early developments in food production and animal domestication. In other words, because China enjoyed critical benefits during the formation of its civilization at such an early stage, it was able to mass up early and thereafter steam-rolled its neighbours in the Southeast and East Asian regions. Leaving in its wake are fragmented but major influences in other countries of today, such as Japan, Korea and/or Southeast Asian countries, by way of language, race and literature. Indeed, as Jared Diamond concludes the chapter, he writes that the â€Å"persistence of Chinese writing in Japan and Korea is a vivid 20th century legacy of plant and animal domestication in China nearly 10,000 years ago† (333) and owing largely to the leaps and bounds advances in farming in the eastern regions of Asia, China became the Chinese of today and traces of its powerful and overwhelming culture can be gleaned from Thailand and other proximate Asian countries—their cousins (ibid. ). Of course, China is not China today solely because of its early advantage in food production and animal domestication as Jared Diamond argues. There are other important factors which taken together with China’s historical development can make for another alternate hypothesis to explain its present day unified state. It would be a little too much of a stretch of the imagination to correlate present times with the circumstances then present several millennia ago. Although Diamond’s premises are elegant and sound, the simplistic and abbreviated accounting of Chinese history leaves more historical questions than it answers. Denis Sinor argues that China did indeed gain a strong foothold in development early on because of its geography (49). But geography is not all that there is available that arguably led to Chinese domination in the region (51). For instance, the occasional barbaric attacks from the Mongol hordes from the north stimulated the solidification of the small communities in China to a powerful unit under one dynastic rule to parry away the constant threat of invasion. Assuredly, food production and animal domestication have little to do with the menace of warfare except for the fact that surpluses in resources can be a motivating factor for the invaders. Still, because of these threats in the Chinese regions, the warring civil clans in China unified to face a common enemy (Sinor 65). In so doing, the Chinese developed a stronger and distinct identity from their neighbours. For lack of a better term, the Sinification was an offshoot of the fact that China has nurtured a crude sense of nationalism as reflected in their literary works, language and cultural masterpieces—including the building of the Great Wall of China simply because unification was a necessity for warfare. Without a doubt, the lasting legacy of the Great Wall bespeaks that need to solidify China at a time when wars from its neighbours were imminent. It is also important to consider the varying political ideologies in ancient and modern China. Its important leaders and other iconic historical figures adopted a monistic approach to its rule. Laws were codified according to the changing needs of the time. This means that the Chinese had a justice system that is inspired the ruling dynasty replete with its own brand of religious, philosophical and social ideas which required everyone to obey with all zest (Sinor 72). Nevertheless, going back to Diamond’s premises, there is no question that food and animal production acted as an impetus for development. Yet to heavily rely on such a primordial causation is to eschew other aspects of Chinese civilization such as its political and social history. True enough certain advantages in geography open doors for a nascent civilization but then again, once that door is opened, there are multitudes of other doors that the choice of one excludes other historical possibilities for a civilization. It just so happens that the Chinese example is a result of a singular development from the start of its development up to the present time.

Cute in Japanese Culture

The rise of cuteness in Japanese culture emerged in the 1970s as part of a new style of writing. Many teenage girls began to write laterally using mechanical pencils. These pencils produced very fine lines, as opposed to traditional Japanese writing that varied in thickness and was vertical. Also, the girls would write in big, round characters and they added little pictures to their writing, such as hearts, stars, smiley faces, and letters of the Latin alphabet. These pictures would be inserted randomly and made the writing very hard to read.As a result, this writing style caused a lot of controversy and was banned in many schools. During the 1980s, however, this new â€Å"cute† writing was adopted by magazines and comics and was put onto packaging and advertising. From 1984–1986, Yamane Kazuma studied the development of cute handwriting, which he called Anomalous Female Teenage Handwriting, in depth. Although it was commonly thought that the writing style was something that teenagers had picked up from comics, he found that teenagers had come up with the style themselves, as part of an underground movement.Later, cute handwriting became associated with acting childishly and using infantile slang words. Because of this growing trend, companies such as Sanrio came out with merchandise like Hello Kitty. Hello Kitty was an immediate success and the obsession with cute continued to progress in other areas as well. The 1980s also saw the rise of cute idols, such as Seiko Matsuda, who is largely credited with popularizing the trend. Women began to emulate Seiko Matsuda and her cute fashion style and mannerisms, which emphasized the helplessness and innocence of young girls. 4] No longer limited to teenagers, however, the spread of making things as cute as possible, even common household items, was embraced by people of all ages. Now there are airplanes painted with Pikachu on the side, and each of Japan’s 47 prefectures, the Tokyo police, and eve n the public broadcaster NHK all have their own cute mascots. Currently, Sanrio’s line of more than 50 characters takes in more than $1 billion a year and it remains the most successful company to capitalize on the cute trend

Financial Assessment and Analysis Essay

Introduction Financial Assessment Investment is something that is important in the life of any human being and should therefore be taken very seriously (Downes, & Goodman, 2003). To make an investment means that one is looking for a better future and also to receive returns form that particular investment. It is important when an individual wants to make any form of investment that they consider a lot of factors which will affect the full operation and conducting of the investment (Downes, & Goodman, 2003). It is also important that an individual who wants to make an investment must ensure that they have sufficient information that will help in making the relevant decisions with regard to the investment that they have in mind. Without prior and clear information, making decisions about an investment is difficult and may result in disaster where one may lose all the amount of cash or funds and waste efforts put up in the business investment (Downes, & Goodman, 2003). In the case of Pierre, having a clear financial assessment of the investment that he wants to engage in will help him in making the relevant decisions which will ensure that he does not operate the business   at a loss in the long run. This financial assessment will make use of assumptions in the establishment of whether the investment Pierre is interested in is relevant and will be profitable. In making an appropriate investment decision, there are various issues to be considered by Pierre which involves the analysis of the financial situation which the investment will require as well as the returns on investment which will be achieved by the business (Gibson, 2012). The first step that Pierre will need to do is to make a consideration of the financial investment which will be need to make the business fully functional. Financial appraisal of projects or investments is important since it helps in making the relevant decisions on what to invest in or not to invest in. When conducting a financial analysis, there are various methods which can be used in appraising a project which involves finances (Gibson, 2012). The method that would be used in apprai8sing the investment by Pierre is the Discounted Cash flow analysis which will help to establish whether the investment which Pierre is interested in is worth the efforts or it should be abandoned (Larrabee, Voss, & John Wiley & Sons, 2013). Financial appraisal is also important to any individual or organization which wants to make an investment since it helps in establishing the amount of returns to expect. This is done through the analysis of the expenses which the investment will incur and the revenues which the investment will be able to raise within a certain period of time (Larrabee, Voss & John Wiley & Sons, 2013). Factors affecting the success of an investment When wanting to make an investment decision, there are various factors which need to be considered so that the decision to be made can be considered to viable. The various factors which Pierre will need to consider will include issues such as: Availability of finances Any investment that an individual or even an organization wants to get involved in always requires finances. The finances which will be put up in the business must be readily available so that one can be able to know whether they can take up the investment or not (Shim, & Siegel, 2007). There must e enough finances which will cater for every put of the start up of the investment since every operation in the investment or business will require sufficient funds (Downes, & Goodman, 2003). In the case of Pierre, he is retired and has an amount of CAD 500,000, whereby he has already paid all the taxes which are involved in the retirement benefits. This is quite a good amount which needs to be invested considering that he is no longer in active employment hence he will need something to generate finances for him, in terms of investment (Shim, & Siegel, 2007). Considering the amount which Pierre has available for investment, it can be considered that he is ready to take up any investment of his choice since he already has available funds which he can put up in business (Cherunilam, 2010). Human capital There is no business investment which can take place if there is no available human capital which will operate the whole investment and make it bring good returns. Human capital is necessary and its availability is important for the success of any investment (Cherunilam, 2010). It is important to ensure that there is readily available human capital which will be able to handle the whole operations of the investment to be undertaken. The cost of human capital should also be considered when wanting to make an investment since human capital that is not affordable will mean that the investment will incur large amounts of costs in terms of the salaries which will be paid out to the employees of the business (Horiguchi, & International Monetary Fund, 1992). In the case of Pierre, he will run the business on his own which is quite good since he will be able to set an affordable amount of cash for the remuneration which he will pay himself. As a sole owner and operator of the business makes it more convenient for him to make the relevant decisions concerning human capital since he does not have to consult anyone on any matter concerning the number of people to have working in the business (Reilly, & Brown, 2012). In addition, Pierre will only have one assistant in the business that will assist in conducting and carrying out the operations of the business. This means that he will not have a lot of expenses with regard to the human capital that he will employ in the business (Downes, & Goodman, 2003). In addition, the human capital is readily available and can be considered affordable hence this is an encouraging factor towards the establishment of the business investment which Pierre is interested in (Kruschwitz, 2006). Government regulations and policies In every country, there are always regulations and policies which are laid down concerning the operation of business and investments. These policies range from the taxes which businesses need to pay, the regulation policies which each business needs to follow as a way of conducting the business within that country among many other policies (Kruschwitz, 2006). The government policies and regulations gives the direction which business investments needs to follow and every business must be able to comply with those regulations and policies within the countries where they operate (Downes, & Goodman, 2003). In the case of Pierre, government regulations that he needs to consider are the taxes which are charged on the kind of business that he wants to establish, the tariffs involved in the importation, especially of chocolate from Switzerland (Horiguchi, & International Monetary Fund, 1992). It will be important that Pierre ensures that he complies with all the government regulations and polices if he wants the investment that he has in mind to succeed. In some instances, the government regulations may prohibit the prosperity of a business investment due to the stringent rules that the business investment is required to accomplish in the long run and the tax rates also may have a negative effect on the business (Downes, & Goodman, 2003). Availability of market Every business investment needs a market where it can be able to operate in and earn good returns. Without there being a ready market available for the products to be sold by the investor will mean that the business will not be able to progress in any way (Horiguchi, & International Monetary Fund, 1992). To know whether there is an available market which the business can be able to obtain good returns, conducting a market research is necessary. Market research is important because it helps in various ways. One, when an investor conducts a market research, they are able to establish the kind of customers available and their purchasing behaviors. This helps in formulating the operations of the business in such a way that it is able to meet the exact needs of the customers and hence obtain a greater market share (Cherunilam, 2010). Market research is important because it also helps the business investor to establish whether there is sufficient demand for the products that he/she wants to offer to the market. From the case study of Pierre, it can be noted that Pierre has taken the initiative to conduct a market research for the business that he wants to establish (Cherunilam, 2010). This has given him the information regarding the kind of revenue that he will be able to make for a certain period. For example, from the market research results, Pierre knows that he will have a demand of 600kg per month while for the first month he knows that he will have a demand of 100kg per month. This information obtained from market research helps in making a sound investment decision, whereby Pierre can choose whether to continue with the investment idea or simply drop it depending on this information obtained from the market research conducted (Cherunilam, 2010). The market research is also important since it helps in establishing the demand and the supply of the product the investor wants to offer in the market. In addition, market research also helps in establishing the kind of competition the business investment is likely to face. Knowing the kind of competition to be faced helps an investor to formulate a strategic plan that will be applied in overcoming the competition when the business investment is established (Shim, & Siegel, 2007). Returns on investment The main reason that influences business investors to engage in any form of business investment is simply to obtain good returns on the finances that they have invested. An investment that is not capable of bring any form of good returns to the business investor cannot be considered to be viable in the long run and hence should not be considered (Shim, & Siegel, 2007). The main objective that business investors have is to make profits and also to expand their businesses. The returns which an investor is able to obtain from his/her investment must be able to provide the investor with profits and also leave him/her with funds that can be used in the expansion of the business (Downes, & Goodman, 2003). In carrying out this investment of importing chocolate from Switzerland and selling in North America, Pierre needs to know what amount of returns will he be able to obtain after all the deductions from the business have been made (Shim, & Siegel, 2007). If the business will not be able to bring god returns, then there will be no need of Pierre getting involved in this kind of investment since he will just be wasting his resources. This can only be determined through the financial analysis of the whole investment that Pierre wants to undertake, which will enable him to make well informed decisions concerning the investment (Gibson, 2012). Costs of investment Business investments always involve a lot of costs which an investor must be able to cater for so that the business can be fully operational. Considering the costs to be incurred when undertaking any business investment is of great importance and any investor must be able to do so (Gibson, 2012). Determining and considering the costs will enable the investor to know whether the finances that the investor has are sufficient to cater for all the costs which the business investment will incur (Downes, & Goodman, 2003). When the cost of investment is too high, the investor will not be able to realize higher returns hence the investment cannot be considered to be viable to be undertaken. A viable investment must have low cost of operation involved so that the business investor can be able to remain with some finances which can be considered as profits (Gibson, 2012). Therefore, in making this investment decision, Pierre must be able to determine and consider the costs involved in the whole business through a financial analysis so as to ascertain whether the investment is viable or worth the risk or it is something that should be abandoned. The above analyzed factors are important to be considered by any business investor who wants to put up their money or finances and efforts into a certain business investment. Pierre needs to make a consideration of all the above mentioned and discussed factors if at all he wants to establish a well operating business investment (Gibson, 2012). As mentioned above, most of those factors can only be determined using real time data and information generated through a financial analysis and assessment of the kind of investment that Pierre wants to undertake. By conducting the financial analysis, it will be possible to identify the returns that the investment is likely to attract, the costs which the investor, Mr. Pierre is likely to incur in the process of opening and operating the business (Manufacturing and investment around the world: An international survey of factors affecting growth and performance, 2002). Valuation The financial analysis that will be conducted in the case of Pierre will involve the formulation of a monthly cash flow for the whole business investment, and the formulation of an annual cash flow for the whole year. The best method of conducting this financial analysis is through the method of discounted cash flow (Kruschwitz, 2006). Discounted cash flow method is simply used to make a valuation and an estimation of the attractiveness of a certain investment opportunity that is available. This method of discounted cash flow (DCF) always makes use of the future free cash flow which has been projected and is discounted at a certain rate but mostly the weighted average cost of capital is used in this method (Damodaran, 2012). This is done so as to obtain the present value which is in turn is used in the evaluation of a particular investment to find out if it is viable. After the calculation of the discounted cash flow, if the value obtained through this method is found to be higher than that of the current value or cost of investment, then the investment opportunity can be said to be a viable one (Schön, 2007). Monthly Cash Flow The monthly cash flow that Pierre is expecting or will experience from the first, month of the investment is that, in the first month, he will be able to have a net cash flow of about CAD 29,193 while for the subsequent months starting from the second month, it is assumed that he will have a constant cash flow of about CAD 102,243. This is expected to occur throughout the year until the end of the first year. The cash flow in the first month is expected to be less because from the market research conducted, it was observed that the amount of stock that he will be able to sell will be about 100kg which is the reason why the cash flow for the first month is lower as compared to the subsequent months. In the second month and the ones that follow, the unit sales increase due to the increase in the stock from 100kg for the first month to about 600kg from the second month. It is also assumed from the calculation of the monthly cash flow that the interest rates will be uniform throughout the year and no inflation will affect the interest rates. Furthermore, it is assumed that the demand for the products will be constant from the second month and there will be no any form of decline or an increase in the demand throughout the first year. Yearly Cash flow The yearly cash flow that Pierre will experience when he starts the investment of selling the chocolates in Americas, the first year is expected to have a cash flow of about CAD 1,204,866 in total. This is the same amount which is expected to be the cash flow for the company or the investment that Pierre is expecting to start. This net yearly cash flow from the first year for a period of five years is assumed to be constant just as the case of the monthly cash flow in the second month of operation. The assumptions made in this case are that: The interest rates will remain constant throughout the five years and there will be no inflation that will take place throughout that period of time. The demand for the products will remain the same throughout the five year period with no change in the prices which will be charged for the products. It is also assumed that the costs involved in the running of the business will remain constant throughout the five years with no increase or decrease on the expenses of the business investment which Pierre is expecting to undertake. The other assumptions which have been made in the calculation of both the monthly cash flow of the business investment and the yearly cash flow of the business is that the investment or business with luxurygifts.com will be undertaken and also Pierre will employ an assistant for the job. It is the assumption of this report and the calculations made that the exchange rate that is to be used to convert the CHF to CAD is taken to be at the rate of 1 CAD is equivalent to about CHF 0.83. This is the rate which has been used to make a conversion of the purchasing price and air transport costs which Pierre is to incur when importing the products from Switzerland. The amount of cash that Pierre could be able to offer to EigerChoc SA as the upfront payment for the exclusive rights of having to sell the products for the period of five years and still leave him no better off or worse if he made the investment decision of engaging EigerChoc in this kind of business would be a total of about CAD 200,000. The reason why he will be able to offer this amount in an easy way is that within a period of half a year, he will be able to obtain good returns which will help bring back his money and make the business fully operational on its own. This amount of about CAD 200,000 will leave Mr. Pierre with an amount of CAD 300,000, assuming that he used his total lump sum amount to start the business. Considering the expenses which he will incur, the amount of CAD 300,000 will leave him more capable of handling all the expenses even if he offers a sum of CAD 200,000 to EigerChoc as an upfront fee. Conclusion Business decision making, especially with regard to making an investment decision sometimes is quite challenging and to some extent a task that requires a lot of information and keenness. It is important that a business investor must be able to obtain all the relevant information that will enable in making the most appropriate decision of investment. Pierre provided sufficient information about the business investment that he wants to get involved in and from the financial analysis on the annual and the monthly cash flow of the business venture, it can be said that the business investment looks attractive for MR. Pierre to undertake. Pierre is in a better position to make this investment because he has all the resources which are needed for the business. The only thing that may inhibit him from undertaking this kind of business is the regulations and government policies which may make it more expensive in terms of the licenses and may be the trade relations between North America and Switzerland. Recommendations The recommendations which Pierre should consider are that: Conduct further research on government policies and regulations regarding the kind of business investment that he wants to undertake He should make use of the lump sum funds that he has instead of borrowing a loon of about CAD 100,000 at an interest rate of 8%. This will increase the expenses of the business hence should not be undertaken at the start of the business. Do not engage luxurygifts.com at the moment. This should be done when the business is fully established to ensure that the expenses involved are not increased. Offer an amount of about CAD 200,000 to EigerChoc as an upfront payment for the business investment. This will leave him with sufficient amount to operate the business. From the analysis of the factors that affecting or determine whether to undertake a business or not and from the calculations of the cash flow that is expected in the business for the period of five years, it would be more advisable for Pierre to undertake the business considering that he already has the knowledge about the market and the kind of demand that his products will command. In addition, through the help of his wife, the business is expected to perform well in the long run and hence it is a viable investment to undertake. References Cherunilam, F. (2010).

Timeline - Essay Example The definition of the computer used today is based primarily in von Neumann’s conception that the computer is a device, which is capable of accepting data input, processing data, storing it and producing data output. The history of computing has progressed from the vacuum tube to the transistor, ultimately to the microchip and modem. This paper will provide a comprehensive timeline of the history of computing, describing the evolution of various computing items through timelines such as 2400 BC–1949,  1950–1979,  1980–1989,  1990–1999,  2000–2009,  2010–2019. 2400 BC–1949 In this period, computing devices focused primarily on enhancing people’s capacities to make calculations. The initial devices used for calculation were tally sticks, with the Lebombo bone being the first known to modern archeology. However, the abacus, developed in 2400BC is the first ever calculator, invented by the Babylonians to enhance sim ple arithmetic. The Chinese abacus (suanpan) was invented in 200BC and was widely used before the invention of present day’s calculator (Isaacson, 2011). ... In 1930, American Vannevar Bush developed a partly electronic difference engine with the capacity to solve differential equations. In 1939, German Helmut Schreyer completed a prototype memory using neon lamps and a 10-bit adder prototype using vacuum tubes. In 1942, Americans Atanasoff and Berry made a special-purpose calculator for system solutions of linear equations, later known as the Atanasoff-Berry-Computer (ABC). German Konrad Zuse created the S1, which was the first process computer that measured the surface of wings (Turner, 2006). In 1944, IBM developed the second program machine, which was 51 feet long and weighed nearly 5 tons. In British, in 1949, the Manchesteer Mark 1’s final specifications were completed. This machine was the first computer to utilize the equivalent of index registers, which entered the second generation computing architecture in 1955. 1950–1979 This period appeared to focus intently on the creation of computer communication and intellig ence. In 1950, the Pilot ACE computer, having 800 vacuum tubes with mercury delay lines as its main memory became functional in the UK (Black, 2001). In 1951, Americans J. Prespert Eckert and John Maunchly designed the first commercially operational electronic computer, UNIVAX, which handled both textual and numeric information. This machine’s implementation was the real start of the computer age (Isaacson, 2011). In 1951, the CIRAC (Council for  Scientific and  Industrial  Research  Automatic  Computer) became the first digital computer used to play music. In 1952, IBM introduced the IBM 701, which was the initial computer in its 700 and 7000 series of large scale machines. In 1960, the initial ordered, technical programming

Work Placement Journal Essay Example | Topics and Well Written Essays - 1250 words

Work Placement Journal - Essay Example ‘Reflection-inaction occurs during the experience and involves making sense of the experience while it is happening.’ Beard & Wilson (2002:197). When being supervised how to distribute medication, I was shown the medication policy – used by the organization, which involved following the following; I realised that the medication policy where the distribution of medication is controlled was just a method or a way of cutting the budget to enhance the survival of the organization. This form of budget cut had adverse impacts on the organization. For example, the controlled medication ensures that less medication is used among the residents and this reduces the funding that the organization may receive. In most cases, when there is no use of resources, then no funding is done. Controlled medication also resuls to understaffing in the organization since the numbers of medications administered to the residents are very few. At this point, i was still a new member of staff therefore, I had to listen attentively to the director of the organization while he was giving me the instructions on medication policy. Through this i came to realise with time that my listening skills were developing. Attentive listening is an effective listening skill [Anderson 1993 page 108]. As the day went on, I was shown how to use the Alcohawk, which is used to breathalyze the residents, which needs to be carried out three times a day by a member of staff.The use of Alcohawk which is minimized to only three times a day by each member of staff was a form of budget cut in the ogarnization. To date, I have carried out five tests with the residents. Once each breathalyze had been done, it must be logged in the medication file so that other staff are aware of the results for next time. If the Alco hawk gave, a reading over 0.001 then that must be investigated and further questions must be asked as to whether the resident in

Mission and Values of Loyola Marymount University Essay

Mission and Values of Loyola Marymount University - Essay Example If my friends are going bungee jumping or parasailing I usually will find that I have something pressing that needs to be attended to immediately, such as tidying my sock drawer. The issue is not if I ever take risks; I do. The real issue for me is deciding if the risk warrants the reward. Fr. Robert Lawton’s words have helped me to see that taking risks in order to discover who I really am during my college career are risks that will pay great rewards. Who doesn’t want to have happiness and a feeling that God approves of who we are and what we are doing? Ultimately, if I accomplish this level of happiness and closeness with God, I will feel as though I have lived a life of real substance and value. Fr. Robert Lawton said that this journey would be risky, and I believe him. In my mind, I see three potential risks that will need to be faced when journeying to discover how to be myself. I believe that if these three risks can be overcome, I will have accomplished somethin g great during my college education in addition to all of the knowledge I will gain. The first of these three risks is the risk that I will discover I am a very different person than I am now. We all have preconceived notions about our state of being. I have a whole list of likes and dislikes. One of my great failings is that I tend to be judgmental about those who have different tastes and values than myself. I catch myself forming opinions about others based on wholly superficial criteria more often than I care to admit. A nice pair of shoes, the type of car and the city or neighborhood a person lives in too often informs my opinion. The risk of journeying to discover my true self and being judgmental of others scares me because I may discover the things I have used to differentiate myself from others really do not matter to me anymore. I guess what I’m trying to say is, I like who I am right now. I recognize that I have much to learn but I am comfortable with me. The risk for me centers on discovering I’m not who I thought I was and that I might mourn the loss of my old self. I have no desire to look back on my high school self and be glad that I am no longer that person. I would like to think I have arrived at most of my authentic self at this point in my life, but I have the suspicion that everyone looks back on their high school self and has regrets. The risk of becoming your true self is you must necessarily reject portions of the person that you are today. To me, that sounds very uncomfortable. A second risk that needs to be overcome on the road to becoming my authentic self is the risk of defying expectations. I have a way I would like to see my life turn out. So do my family and friends. The risk of opening myself up to change is apparent when I realize that the change may disappoint some of the people I love. I will be exposed to new people and ideas at college. What if I find myself changing course and it is a course I’m not su re my loved ones will accept? I feel that taking this risk to find my true self will be perhaps the hardest. My family has always been loving and supportive. I would never want to disappoint them in any way. But according to the words of Fr. Robert Lawton, I may need to take that risk or I may be sacrificing my own happiness and relationship with God. A final risk I anticipate in this journey is never knowing when you have arrived at the journey’s end. How will I now when I have arrived? I know too many people from my parent’s and grandparent’s generation that seem to think their happiness lies in their new yoga class or the next protest movement they can join. They seem to be constantly seeking but never finding what they are looking for. I think they are looking for a sense of self. The risk for me looking to identify my true

Anselm's ontological argument Essay Example | Topics and Well Written Essays - 1000 words

Anselm's ontological argument - Essay Example Whereas ancient Greek philosophers, such as Plato and Aristotle, hinted at the existence of a God, Anselm’s ontological argument offered one of the first expressly rational proofs for the Judeo-Christian God. In this paper, the author examines the ontological argument of St. Anselm by taking a look at the argument itself, and analyzing both the value and criticisms against it. Further, the discussion examines the influence of the ontological argument on modern thought, particularly Rene Descartes’ revival of the said proof. The ontological argument derives its name from â€Å"ontos†, meaning â€Å"being†. The term â€Å"ontological† signifies an emphasis on the â€Å"being† or â€Å"nature† of an entity. An ontological argument, therefore, derives its strength from the nature itself of what is argued for. In the case of the ontological argument of Anselm, it is referred to as such because it seeks to prove the existence of God by appealing to the nature of this Supreme Being, or perhaps more correctly, to the definition of the latter. He argues that to have an understanding of God as that than which nothing greater can be conceived, entails the acceptance of God’s existence since such a conception necessitates existence. He states: Therefore, if that than which nothing greater can be conceived, exists in the understanding alone, the very being than which nothing greater can be conceived, is one than which a greater can be conceived. But obviously, this is impossible. Hence, there is no doubt that there exists a being than which nothing greater can be conceived, and it exists both in the understanding and in reality (Fremantle 89). It can be seen that such a proposal allows for a proof that is â€Å"built in† the term, so to speak. For if God is such a being, then it is of necessity that he must exist, since not to exist would mean that there is another being that is greater still, namely, one that exists. Thus, Anselm quotes Psalm 14:1

Toyota 2010 Term Paper Example | Topics and Well Written Essays - 500 words

Toyota 2010 - Term Paper Example This meant that the driver would not always be able to stop the car when he pulled the brakes consequently causing serious accidents (Jackwin, 2010). The second recall was made on January 21, 2010. Numerous crashes were reported which could not be explained by the floor mat incursion. Research indicated problems with the mechanical sticking of the accelerator pedal which Toyota labels sticking accelerator pedal. After a series of research findings Toyota recalled approximately 5.2 million vehicles with regards to the floor mat problem and an additional 2.3 million with regards to the accelerator problem (Stewart, 2010). These decisions were a result of numerous investigations carried out by Toyota along with the U.S. NHTSA and Japanese transport ministry. After numerous complaints being filed, US safety regulators carried out an investigation into Corolla steering complaints on Feb 17, 2010. The biggest challenge facing the investigators was to differentiate between accidents caused by mechanical or technical faults in the vehicles and those that were merely a result of driver error. Both the Wall Street Journal and USA Today suggested that even when the dealers and automakers realized the cause was driver error it was not always possible for them to say it explicitly, so as to avoid appearing insensitive to their customers (United States, 2010). Investigations were also carried out by Ministry of Land, Infrastructure, Transport and Tourism (MLIT). The MLIT investigated on the sudden acceleration complaints and released its findings in February 2010. Revealing that out of the 134 cases logged by the ministry between 2007 and 2009, Toyota accounted for 38 cases. However it also stated that since Toyota’s market share was huge approximately 28% the rate found was not unusual. When confronted with the issue the president and CEO of Toyota Akio Toyoda issued a statement

Treatment of Law Enforcement in Todays Society Essay

Treatment of Law Enforcement in Todays Society - Essay Example Many of the different approaches to dealing with crime comes out of various assumptions and values. For countries or systems that believe a criminal is a product of his or her environment, it is more likely that money will be spent on rehabilitation and treatment, with much less of an emphasis on jail time. For these sorts of people law enforcement can be as simple as footing the bill for an Alcoholics Anonymous session. But for those who believe people are responsible for their own actions and intend to commit crimes (indeed intention or mens rea is required in all common law systems in order to convict someone of a crime), the emphasis is likely to be on punishment or locking up the criminal. Law enforcements in this case is about protection and to some extent about retribution. People from both sides of these arguments treat law enforcement differently. Clearly these concepts require a great deal of unpacking—which will be done in the course of this essay. The key things to examine are the various explanations for why people commit crimes, be they biological, psychological and sociological, and how law enforcement should deal with these criminals. In the law enforcement system there are two opposing modes of looking of how to deal with criminals. The first is the due process model. The gist of this model is that an individual can never be deprived of basic human rights no matter how horrible a crime he or she has committed. Even for the police or DA to put someone in prison is to take away the criminal’s inalienable right to liberty. In the course of this system there must be many appeals and a thoroughly scrutinized process to ensure that everything is done by the book (Samaha, 22). At its heart the due process model would rather see nine guilty people on the street than one innocent person in prison. The end result of this mode

Changes in Earth's Albedo Measured by Satellite (Wielicki et al, 825) Essay

Changes in Earth's Albedo Measured by Satellite (Wielicki et al, 825) - Essay Example The global albedo is found to change with changes in the cloud cover, amount of atmospheric aerosols, and forest, snow, & ice cover on the earth’s surface. The magnitude of impact on global albedo due to events caused on earth can be demonstrated by the following example – A volcanic eruption in Mount Pinatubo in June 1991 released aerosols in the stratosphere, which raised global albedo by almost 0.007 in a span of two years. A larger increase in global albedo with unknown causes was reported to occur between 2001 and 2003. In order to investigate whether any significant changes in global albedo occurred between 2001 and 2003, Wielicki et al. examined the observations made by global satellites that measured changes in the earth’s albedo (825). These observations included those made by CERES (Clouds and Earth’s Radiant Energy System) of NASA’s Terra spacecraft. The monthly anomalies in the data caused by seasonal changes were nullified and data was plotted. The data provided by CERES covers global observations for the complete solar spectrum ranging from a wavelength of 0.3 to 4 Â µm. The observations of the global data reveals a small decrease of about 0.006 in the global albedo corresponding to about 2 W m-2 decrease in the shortwave reflected flux. These results contradict with those obtained by Palle et al, who demonstrated a large increase of about 0.017 in the global albedo corresponding to an increase of about 6 W m-2 in the shortwave reflected flux. Independent observations made by two individual CERES instruments were compared. It is believed that the 1.1 W m-2 decrease in the flux observed by one of the CERES instruments could be due to exposure to ultraviolet radiation during a hemispheric scan. When taken into consideration, this further reduces the anomaly to 0.9 W m-2. Wielicki et al. further explain the effect of change in albedo on earth’s climate (825). When changes in land surface, aerosols, and fores t, snow and ice cover is the cause for change in albedo, then increasing albedo results cooling of the earth and decreasing albedo results in warming. These changes on earth’s surface significantly influence the amount of reflected solar radiation but have comparatively minor effects on the emitted thermal infrared radiation that results in cooling. Wielicki et al. contend that if observations made by Palle et al. were correct, then there would have been global cooling double of what had been observed in the Pinatubo eruption. However, such a global cooling was not observed. Furthermore, Wielicki et al. explain another possibility that the earth’s total ocean heat storage could witness a significant reduction. It is estimated that between 2000 to 2002, the ocean heat storage has experienced an increase of 0.7 W m-2. In order to account for the global changes in reflected solar flux, the flux in ocean heat storage was scaled to global surface area from an ocean-only are a utilized by Willis et al (Wielicki et al. 825). According to Wielicki et al, if changes in global albedo were occurring, then there would be a decrease of 0.7 Â ± 0.8 W m-2 in the reflected flux. This is found to be consistent with the observations made by CERES. Until now, only the effects of change in albedo have been discussed. Cloud changes may also be affecting both the earth’s albedo and its thermal infrared cooling, and may also be a cause for albedo changes that do not

Language changes during the play Essay Example for Free

Language changes during the play Essay Sheila takes the inspectors lessons to heart, and appears changed by the incident. In Act Two, Sheila sums up the whole familys reactions to the Inspectors questions. She reminds them of the greed, jealousy and selfishness they have all shown. It means we have no excuse now for putting on airs. This is just the start of the speech and she admits responsibility but is very frustrated that the others dont. She has clearly changed.  The audience will have noticed a dramatic change in her personality. She has been affected a lot by the death. She has changed from a jolly and self-centred person to a conscious and very guilty person. If any of the characters were going to change, or learn from the mistakes it would be Sheila. She shows a great deal of interest in Eva Smith/Daisy Rentons death right from the start and throughout. She also feels a lot of guilt and is the only character that is sorry. Her maturity during the interview is much higher than any other character as she is the only one to accept responsibility. Sheila is also the only one who emphasizes her mistake by saying she was very jealous.  Sheilas language changes during the play. She starts off speaking like a child, using words like mummy. She also typically squabbles with her brother. Her language begins to mature and become much more serious during the questioning and after. She begins to take control with the Inspector, trying to help them understand their part in the girls death. Priestley wants the audience, again to understand that honesty is very important. But also that everybody is responsible for each other. Society depends on responsibility for others and Sheilas character should highlight this.  Eric is a spoilt, moody and irresponsible man. (Sulkily) Im all right. Eric is sulking when he utters this line and it gives the impression that he is very young. This is because a lot of children sulk when they are unhappy and Eric is being very childish in doing this. This shows immaturity. I dont give a damn now whether I stay here or not. This suggests his immaturity and selfishness. He isnt in the best of moods after what happens and gets very moody and out of control. Eric lacks self-discipline. His immaturity during this encounter shows much more than the rest and so does his lack of self-discipline. He is old enough to know better.  (Almost threatening her) You dont understand anything. You never did. You never even tried you. This is the worst of Erics anger he does end up calming down. Eric is very distressed by the situation and cannot handle it. He is also very guilty and he does understand the mistake he has made. This is a rare bit of maturity from Eric. Though he is not a pleasant character, we may feel that he has learnt a lesson, that he is sincerely ashamed of his behaviour and he is capable of changing for the better. (Unhappily) My God Im not likely to forget. Eric is aware of the mistake he has made and feels a lot of shame and guilt. Like Sheila, Eric has learned his lesson and they both will learn their lesson. However, their parents dont feels the way they do and dont think anybody has done anything wrong, and this is what really frustrates Eric. Eric is the youngest child in the family and this is fairly noticeable because he speaks with great immaturity. He is rude and very hard to get on with. He uses demanding but very childish words, as if to draw attention. But his attitude and language change when the inspector questions him, and unlike most of the others, feels a lot of guilt, shame and wants to learn from his mistakes. Even when they find out the Inspector might have been a fake he still remained remorseful and full of pity. Priestley may have used Eric to represent the idea that nobody is perfect. Learning from mistakes will make you a much better person. Eric has done a lot of things wrong during his life, being rude and impolite to family members and also thieving and deceiving others. He has without doubt the worst history but he is mature enough to learn from this. Priestley may have also used Eric to represent the emotions that, if the audience were in a similar situation, might act like. He gets frustrated that his parents wont accept his guilt and does tend to lash out. Priestley uses the Inspector to convey his own ideas about morality to the audience. Rather than representing a real person, his character represents the abstract idea of human conscience, which ensures consideration and responsibility for others. He calls himself Inspector Goole. The word Goole has connotations of being ghostly, spiritual and non-human. Priestley could have wanted the inspector to be a kind of ghost and play on the characters conscience. We get the sense that he is some kind of supernatural force. Being called Goole gives the audience some idea he may not be real but he manages to control the situation and dominate the situation. He gets into the characters conscience and makes them reveal all. He does this by asking demanding short questions. Well? This question is very short but has so much power to it. He speaks as though he was a boss talking to an employer, or as if he was a teacher speaking to a student. He gets so much out of the characters by asking one-liners like this. This also shows confidence, Inspector Goole now believes he has taken control, which he Cleary has done, and starts to use these demanding questions. He is not afraid to contradict and be rude to his social superiors. (Cutting in) Never mind about that. The quote shows the inspector interrupting the flow of the conversation. The family would obviously not approve of butting in as they are supposed to be such a polite and well-bred family. By inspector Goole showing no fear in doing this it shows his dominance. He sets himself up as the boss in the whole situation right from the start and this is something Mr and Mrs Birling find hard to deal with.  Priestley wants the audience to ask themselves how responsible are we for others in society? He uses five different characters with five very different reactions to the situation. Mr Birling feels he has nothing to do with the death and the girl is at fault. Mrs Birling doesnt want anything to do with it and she doesnt have the time. Sheila on the other hand reacts totally differently from Mr and Mrs Birling, she is very sorry for what she has done. She seems very interested in the whole situation. She shows a lot of emotion and promises she will learn from her mistakes.  Gerald makes it quite clear that he is sorry for what he had done but shows little emotion. He does remain very honest throughout. Though when he finds out the inspector was a fake he starts to show less and less guilt and much more relief. Eric is certainly the most emotional of all the characters. He is very sorry and upset by the whole situation. We can tell by his reaction that he is the youngest in the family, as he becomes very moody and frustrated, at some point he almost breaks down. Its like the whole thing is too much for him to handle. Like Sheila he definitely learns his lessen and is willing to change. Now, the audience can look at each character and think, which one am I most like? Would I feel guilty? Would I be emotional and very sorry? Would I remain very honest? These are all questions Priestley wants the audience to ask themselves. Overall, the main question is, how responsible are we for others in society?  In my opinion Priestley succeeded in getting this moral question across. He certainly encouraged me to ask myself these questions.

Speech And Language Therapy For Children

Speech And Language Therapy For Children The Speech and Language Therapy profession is arguably one of the most important in Irish healthcare today. Its combat against the prevalence of communication disorders in this country especially for young children up to five years of age, in their crucial development stage, is fundamental in enabling those that could not otherwise manage it themselves, participate normally in society. But the last decade has seen a steady rise in such cases accessing public speech and language therapy services and the resources are currently not meeting existing and future demand. In fact quite the opposite is happening; public resources managed by the HSE are in decline as cuts to HSE budgets have been a constant since the beginning of the recession. Waiting lists for the public services are at an all-time-high and demand for private services have risen as a consequence but overall, children with speech and language needs are in a state of neglect and these needs will become more complex and problematic the longer they wait. Introduction. There are a lot of problems in our health system today that are apparently being addressed by the concept of reform. But somewhere within this system in reform there is an immerging issue of pretty dire proportions. Communication in human beings is a fundamental and natural skill that shapes the very world we live in. To not be in possession of such a seemingly basic skill would to essentially, be left out of society. Hard to imagine, yet thousands of children in the country each year present with communication difficulties. Speech and Language Therapy addresses these difficulties and with great success however such difficulties left untreatedà ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ What is Speech and Language Therapy? Classified as a healthcare profession Speech and Language Therapy aims to assess, diagnose and manage those who have difficulties with their communication skills. Speech and Language Therapy enables those with such difficulties to achieve their full potential to communicate and therefore integrate properly into society. Children with speech and language issues are among a very common group that are at a risk of developmental, learning, behavioural and social difficulties. Between 50-90% of children aged three with communication deficiencies will continue to have difficulties throughout their childhood. (HSE.ie Speech and Language Therapy. 2013). Image www.arcspeech.ieSpeech and Language skills are vital to a childs development which happens through communication. Language forms the very basis of communication for which reading, writing, speaking and listening are all part of. The ability to communicate is crucial for children to communicate with their peers. Children with delayed language development entering their first year in school are at risk of not being able to access the school curriculum. (ARC Speech Language Therapy Clinic 2013). The key to a more successful outcome for communication disorders is early intervention. When Would a Child Need Speech and Language Therapy? Guidelines. There are general guidelines for parents who may suspect that their child might be in need of or may benefit from speech and language therapy. For example, if the child has difficulties understanding instructions compared to other children, is late in development of talking, has a hoarse voice, has a stammer or stutter, finds playing with peers challenging or is not interested in interacting with others or is 3 and there is difficulty understanding their speech. (Irish Association of Speech Language Therapists. 2013). Typical stages of speech and language development for parents to understand at what stage their child should be at are outlined in the table below. Figure : Typical Stages 6 to 9 months 9 to 12 months 12 to 15 months 15 to 18 months 18 to 24 months 2 to 3 years 3 to 4 years 4 to 5 years Babble a long string of syllables aloud Point and imitate. Say yes and no and shake head accordingly Understand and respond to simple instructions. Be able to say 6 to 20 words and understand even more. Have a range of up to 50 phrases. Ask for food and drink. Understood 50 to 75% of the time. 3 to 4 words together in a sentence. Understand opposites. Ask Why questions. Understood 80% of time. 6 word sentences. Recognise some words in books/signs. More complex sentences with few errors. (Catriona Lysaght Speech and Language Therapist. 2013). My Child is Not Following the Typical Stages. All children develop at different rates and a parent knows their child best (Catriona Lysaght 2013) but a parent whose child does not seem to follow or fit the typical development stages, should have reasonable cause for concern and talk to their G.P. who can form their own opinion and refer to a Speech and Language Therapist if necessary. Assessment. The very first step to the Speech and Language process is always the initial assessment in which to gauge the childs speech and language skills in relation to the typical stages of speech and language development. The assessment is child age and ability specific and the parent normally will have completed a questionnaire to give the therapist a good understanding of the childs skills. General Assessments. Some of the general things that the therapist assesses during the initial assessment may include: Figure : Assessments Speech Sounds The sounds that the child uses to make words and how the child uses those words themselves as part of their language. Oro-motor/Motor Speech The childs ability to move the mouth muscles for both speech and non-speech tasks. Receptive Language Skills The childs understanding of language used by others around them. Expressive Language Skills How the child uses words to expresses themselves. Fluency/Stuttering/Stammering The therapist examines the characteristics of the childs stammering. Feeding, Eating, Drinking and Swallowing (FEDS) Only for children with difficulty in the area, the therapist observes the childs eating to assess things like chewing skills, drooling and ability to feed independently. (Irish Association of Speech Language Therapists. 2013). Image www.spectrumhealth.ie Feedback. Once the initial assessment has been completed the therapist will give the parent verbal feedback on their findings and discuss the results of the assessment. A plan for moving forward to best suit the needs of the child is also discussed along with whether or not the need for a block of speech and language therapy is required. (Irish Association of Speech Language Therapists. 2013). Potential Issues. Speech and language issues for a child could also indicate other potential issues for that child that otherwise could not be determined at an earlier stage of their development. While most children who attend speech and language therapy benefit greatly from the intervention, for some parents it can mean the realisation on an underlying issue such as Autism or Attention Deficit Hyperactivity Disorder (ADHD). Early Intervention. Prompt assessment and early intervention is critical if the long-term implications of a speech and language impairment is to be successfully reduced. (HSE.ie Health Service Executive Website Speech and Language Therapy. 2013). The earlier a child is assessed and diagnosed for treatment, the earlier that treatment can begin and the more successful the treatment will be. Children have a window up to the age of five of prime time for brain development and ideally any therapy treatment should be during this time. The older the child, the least effective the therapy is so early intervention is key. Image www.speechlanguagetherapyni.com Services: Public vs. Private. Public speech and language therapy services are free in Ireland but there are private alternatives for a family who wish to have their child seen to much more quickly than they could be seen to by the public service. Private services can also offer more regular, specialist services with more flexible hours and the associated costs are mostly covered by many of the health insurance companies but the outlay can be expensive overall. Parents who simply cannot afford to have their child seen privately have little alternative but to join the public waiting list. Speech and Language Therapy Demand in Ireland. It is estimated that over 5% of children will experience a Speech and Language delay which means that up to 6,000 children each year will have a specific speech or language impairment by the time they reach the school-going age. (Cluas.ie | Speech and Language Therapy| Language Development. 2013). With the increase on birth rates in Ireland today, this figure is likely to increase. The demand for speech and language therapy in Ireland has been steadily rising over the last decade as figure 3 shows: Figure : People Accessing Primary Speech and Language Therapy in Ireland (Department of Health, 2012) Speech and Language Resources in Ireland. Public resources for Speech and Language Therapy have drastically reduced since the beginning of the recession where recruitment bans across the Health Service have impacted heavily on the patient-to-therapist ratio that have seen waiting lists grow longer and longer up to 2 years in some areas (Irish Examiner 2013). Desperate parents have been flocking to their local TDs as a last resort and a number of them have pleaded on their constituents behalf in the Dail for a lifting of the ban specifically for Speech and Language Therapists e.g. (Patrick Nulty 2013). Therapists themselves are feeling the stresses and strains of the system where the long waiting lists are the main source of frustration (HSE.ie Speech and Language Therapist 2013). They are only too aware of the ticking clock that is the development window of each child on the list. All of this in contrast to the promises made by the Minister for Health in 2011 for radical reform across the health sector (James Reilly 2011). Conclusion. With the rising demand for speech and language therapy coupled with reductions in public services, the very foundation of speech and language development; early intervention has become a contradiction in terms. Paradoxically, the relatively small savings currently being made with recruitment embargos in the health service are very likely to be overshadowed by the future costs that will be associated with developing the children whose needs are not currently being met. This might make some economic sense to those who maintain that the funds simply are not there now to meet current demands but on a human level, its simply unjust to expect children to delay their own learning development for the sake of economics. Recommendations. Resources for speech and language therapy need to be restored to appropriate levels to handle current demand with priority given to the areas in most need; with the longest waiting lists and lower patient-to-therapist ratios. Similarly reforms within the health service, especially in this field are desperately required and long overdue. The Government and HSE must deliver on their reforms promised in 2011 to reduce waiting lists across the health system (James Reilly 2011).

B Cell Activation in HIV Infection

B Cell Activation in HIV Infection During HIV infection, B cells can be activated by HIV virions, plasmacytoid dendritic cells, infected macrophages and CD40 ligands. Mannose binding lectin (MBL), a C-type lectin, is in a complex with the MASP (MBL-associated serine proteases) enzyme and is involved in recognising and binding carbohydrates on pathogens (e.g. HIV envelope protein gp120 is highly glycosylated). When the carbohydrates are recognised, MBL activates the enzyme activity of MASP which causes the activation of the complement system by cleaving C2 and C4 complements resulting in the formation of C3 convertase. This activation and formation of C3 convertase is known as the alternative pathway of the complement system. C3 complement is cleaved by the C3 convertase enzyme and C3 fragments (C3d/C3dg, iC3b) are formed from this breakdown. These fragments are deposited onto the HIV virion surface. HIV IC (immune complexes) interact with CD21 (complement receptor) on B cells and C3 fragments acts as a mediator in the IC-CD21 interaction. CD21 is involved in the activation of B cells and a constant IC-CD21 activation could trigger the polyclonal a ctivation of B cells in HIV viremia. (1-4) Plasma dendritic cells (pDCs) express TLR9, TLR7, CD4, CCR5, CXCR4 and MCLR receptors. TLR7 receptor is stimulated by its interaction with viral ssRNA and TLR9 by its interaction with unmethylated DNA motifs of the viral genome. Stimulation of these receptors leads to the activation of intracellular pathways both of which involves the activation of the adaptor protein, MyD88. The MyD88-IRF7 pathway involves the activation of IRF7 by MyD88 which goes on to regulate the gene transcription of Type I IFN, leading to Type I IFN production by pDCs. NF-kB is also activated by MyD88 and causes the production of pro-inflammatory cytokines such as TNF-ÃŽ ± and IL-6 by upregulating their gene transcription in pDCs. IFN-ÃŽ ± (a Type l IFN) induces the activation and differentiation of B cells into plasmablasts. The presence of IL-6 causes differentiation of plasmablasts into antibody secreting plasma cells. TNF-ÃŽ ± is involved in the polyclonal activation of B cells. The production of Type I IFN upregulates the mRNA expression of two cytokines involved in stimulating B cells in pDCs. These cytokines cause the activation, proliferation and survival of B cells, immunoglobulin class- switching and are known as BAFF (B cell activating factor) and APRIL (a proliferation-inducing ligand). Both cytokines belong to the tumour necrosis factor (TNF) ligand family. BAFF interacts with B cells by binding to the BAFF receptor (BAFFR) located on the surface of B cells. Plasmacytoid dendritic cells also activate B cells through the interaction of their CD70 ligand with the CD27 receptor on B cells, causing proliferation and differentiation of memory cells into plasma cells. HIV infected macrophages, activate B cells by Nef protein indirectly when it is taken up and expressed de novo by infected macrophages. HIV Nef induces the production of ferritin through the NF-ÃŽ ºB pathway causing gene transcription and releasing ferritin from the infected macrophages. Adequate production of ferritin induces proliferation of resting B cells into antibody secreting plasma cells by upregulating the expression of B cell gene. This activation of B cells can lead to hypergammaglobulinemia the increase in the level of gamma globulins (immunoglobulins) in the blood. (1,20) Figure 1 shows adequate levels of ferritin can lead to increase in immunoglobulin (Ig) levels in the plasma (hypergammaglobulinemia). To determine whether there is a correlation between hypergammaglobulinemia (B cell dysfunction) and plasma ferritin level in HIV infection. Plasma Ig levels were compare to plasma ferritin levels of 83 infected HIV infected people. The results obtained show that there is a positive correlation between plasma ferritin levels and plasma levels of IgA, IgG and IgM in the HIV infected individuals studied. As plasma ferritin levels increased, plasma IgA, IgG and IgM levels also increased generally. (20) The outer layer (envelope) of HIV virions contains viral protein, gp120, which can directly bind to receptors on B cells. Activation of B cells by gp120 causes polyclonal immunoglobulin class switching. This occurs in the presence of BAFF which binds to its receptor on B cells, BAFFR and gp120 binds to MCLRs (mannose-binding C-type lectin receptors) on B cells. The interaction causes IgM to switch to IgG and IgA through the upregulation in the expression of the activation-induced cytidine deaminase, an enzyme involved in class-switch DNA recombination. The HIV gp120 has also been found to inhibit the production of IFN-ÃŽ ± by pDCs by affecting the activation of the TL9 pathway involved in its production. The protein, gp120 binds to CD4, CCR5, CRCR4 and MCLR receptors on pDCs and its binding to CD4 and MCLR has been found to not produce IFN-ÃŽ ± by the TLR9 pathway. This prevents the activation of B cells by the TLR9 pathway through the release of IFN-ÃŽ ±. (7,9,10,21) B cells can also be activated by the interaction between CD40 receptors on B cells and CD40 ligands on T cells in the presence of cytokines (e.g. IL-10). This interaction activates the B cells to differentiate and undergo immunoglobulin class switching by causing class-switch recombination. Class-switch recombination is induced by the activation of NF-kB transcription factor which induces the gene expression of activation-induced cytidine deaminase (AID). However, during HIV infection CD4+ T cells are targets for the HIV virus so number of CD4+ T cells are depleted suppressing this activation of B cells.

Federal Mandates :: essays research papers

Federal mandates can be very important to the well being of U.S. citizens. Mandate 13031 is for the protection of one of the natural rights of every U.S. citizen; life. The term "child abuse" means the physical or mental injury, sexual abuse or exploitation, or negligent treatment of a child. This mandate outlines the regulations of who is responsible for reporting possibilities of child abuse. This mandate is responsible for saving the lives of many abused children. Federal Mandate 13031 falls under U.S.C. Title 42 - The Public Health and Welfare, Chapter 132 - Victims of Child Abuse, Subchapter IV - Reporting Requirements. It leaves the responsibility of reporting suspicions of child abuse with a great number of people. Any one in the medical profession including: physicians, dentists, medical residents or interns, hospital personnel and administrators, nurses, health care practitioners, chiropractors, osteopaths, pharmacists, optometrists, podiatrists, emergency medical technicians, ambulance drivers, undertakers, coroners, medical examiners, alcohol or drug treatment personnel, and persons performing a healing role or practicing the healing arts are required to report child abuse. Other professions included in the mandate are: psychologists, psychiatrists, social workers, licensed or unlicensed marriage, family, and individual counselors, teachers, teacher's aides or assistants, school counselors and guidance personnel, school officials, and school administrators, child care workers and administrators, law enforcement personnel, probation officers, criminal prosecutors, and juvenile rehabilitation or detention facility employees, commercial film and photo processors. Lastly, the parents and/or foster parents are responsible for reporting any suspicion of child abuse or neglect. Despite the large numbers of responsible persons in this mandate, it has only a small impact on the local & state budget priorities. For most of these professions it is normal practice to check for signs of child abuse. It takes very little time and very few resources to look a child over. However, if a child is found to be abused, the costs of investigation, prosecution, and further care of the child can be very expensive. Due to this, there is millions of dollars appropriated each year for the area of child abuse. Any mandate that deals with the safety of children should never be removed. However, this particular mandate could probably be done without. The mandate simply shows who is required to report suspicions of child abuse. Although it doesn't sound very important, the number of abused children would probably continue to rise.

Egyptian Tombs :: World History Essays

Egyptian Tombs Egyptologists had lost interest in the site of tomb 5, which had been explored and looted decades ago. Therefore, they wanted to give way to a parking lot. However, no one would have ever known the treasure that lay only 200 ft. from King Tut's resting place which was beyond a few rubble strewn rooms that previous excavators had used to hold their debris. Dr. Kent Weeks, an Egyptologist with the American University in Cairo, wanted to be sure the new parking facility wouldn't destroy anything important. Thus, Dr. weeks embarked in 1988 on one final exploration of the old dumping ground. Eventually he was able to pry open a door blocked for thousands of years, and announced the discovery of a life time. "We found ourselves in a corridor," he remembers. "On each side were 10 doors and at end there was a statue of Osiris, the god of the afterlife." The tomb is mostly unexcavated and the chambers are choked with debris, Weeks is convinced that there are more rooms on a lower level, bringing the total number to more than 100. That would make tomb 5 the biggest and most complex tomb ever found in Egypt, and quite conceivable the resting place of up to 50 sons of Ramesses II, perhaps the best known of all the pharaohs, the ruler believed to have been Moses' nemesis in the book of Exodus. The Valley of the Kings, in which Tomb 5 is located, is just across the Nile River from Luxor, Egypt. It is never exactly been off the beaten track. Tourism has been brisk in the valley for millenniums: graffiti scrawled on tomb walls proves that Greek and Roman travelers stopped here to gaze at the wall paintings and hieroglyphics that were already old long before the birth of Christ. Archaeologists have been coming for centuries too. Napoleon brought his own team of excavators when he invaded in 1798, and a series of expeditions in 19th and early 20th centuries uncovered one tomb after another. A total of 61 burial spots had been found by the time the British explorer Howard Carter opened the treasure-laden tomb of King Tutankhamun in 1922. Britain's James Burton had burrowed into the site of Tomb 5 in 1820, and decided that there was nothing inside. A dismissive Carter used its entryway as a place to dump the debris he was hauling out of Tut's tomb. In the late 1980s, came the proposed parking area and Weeks' concern. His 1988 foray made it clear that the tomb wasn't dull as Burton said. Elaborate carvings covered walls and referred to Ramesses II, whose

Visual Diagnosis Of Melanomas Health And Social Care Essay

Amelanotic melanoma is a type of skin malignant neoplastic disease in which the cells do non do melanin. They can be pink, ruddy, violet or of normal tegument colour, therefore hard to acknowledge. It has an asymmetrical form, and an irregular faintly pigmented boundary line. Their untypical visual aspect leads to detain in diagnosing, the forecast is bad. Recurrence rate is high. Figure: 3.11. Amelanotic melanoma on Canis familiaris ‘s toe3.12.10 Soft-tissue melanomaClear-cell sarcoma ( once known as malignant melanoma of the soft parts ) is a rare signifier of malignant neoplastic disease called sarcoma. It is known to happen chiefly in the soft tissues and corium. Rare signifiers were thought to happen in the GI piece of land before they were discovered to be different and redesignated as GNET. The return for such sort of melanoma is common. Clear cell sarcoma of the soft tissues in grownups is non related to the paediatric tumour known as clear cell sarcoma of the kidney. Under a microscope these tumours show some similarities to traditional tegument melanomas, and are characterized by solid nests and fascicules of tumour cells with clear cytol and outstanding nucleole. The clear cell sarcoma has a unvarying and typical morphological form which serves to separate it from other types of sarcoma.3.13 Diagnosis:Ocular diagnosing of melanomas is still the most common method employed by wellness professionals. Gram molecules that are irregular in colour or form are frequently treated as campaigners of melanoma. The diagnosing of melanoma requires experience, as early phases may look indistinguishable to harmless moles or non hold any colour at all. Peoples with a personal or household history of skin malignant neoplastic disease or of dysplastic nevus syndrome ( multiple untypical moles ) should see a skin doctor at least one time a twelvemonth to be certain they are non developing melanoma. There is no blood trial for observing melanomas. To observe melanomas ( and increase survival rates ) , it is recommended to larn what they look like ( see â€Å" ABCDE † mnemonic below ) , to be cognizant of moles and look into for alterations ( form, size, colour, rubing or shed blooding ) and to demo any leery moles to a physician with an involvement and accomplishments in skin malignance. A popular method for retrieving the marks and symptoms of melanoma is the mnemotechnic â€Å" ABCDE † : Asymmetrical tegument lesion. Boundary line of the lesion is irregular. Color: melanomas normally have multiple colourss. Diameter: moles greater than 6A millimeters are more likely to be melanomas than smaller moles. Enlarging: Enlarging or germinating A failing in this system is the diameter. Many melanomas present themselves as lesions smaller than 6A millimeter in diameter ; and all melanomas were malignant on twenty-four hours 1 of growing, which is simply a point. An sharp doctor will analyze all unnatural moles, including 1s less than 6A millimeter in diameter. Seborrheic Keratosis may run into some or all of the ABCD standards, and can take to false dismaies among laypeople and sometimes even doctors. An experient physician can by and large separate seborrheic keratosis from melanoma upon scrutiny, or with dermoscopy. Some advocate the system â€Å" ABCDE † , with E for development. Certainly moles that alteration and germinate will be a concern. Alternatively, some refer to E as lift. Elevation can assist place a melanoma, but deficiency of lift does non intend that the lesion is non a melanoma. Most melanomas are detected in the really early phase, or unmoved phase, before they become elevated. By the clip lift is seeable, they may hold progressed to the more unsafe invasive phase. Nodular melanomas do non carry through these standards, holding their ain mnemonic, â€Å" EFG † : Elevated: the lesion is raised above the environing tegument. Firm: the nodule is solid to the touch. Turning: the nodule is increasing in size. A recent and fresh method of melanoma sensing is the â€Å" ugly duckling mark † . It is simple, easy to learn, and extremely effectual in observing melanoma. Simply, correlativity of common features of a individual ‘s skin lesion is made. Lesions which greatly deviate from the common features are labeled as an â€Å" Ugly Duckling † , and further professional test is required. The â€Å" Small Red Riding Hood † mark suggests that persons with just tegument and light-colored hair might hold difficult-to-diagnose amelanotic melanomas. Extra attention and cautiousness should be rendered when analyzing such persons, as they might hold multiple melanomas and badly dysplastic birthmark. A dermatoscope must be used to observe â€Å" ugly ducklings † , as many melanomas in these persons resemble non-melanomas or are considered to be â€Å" wolves in sheep vesture † . [ 28 ] These fair-skinned persons frequently have lightly pigmented or amelanotic me lanomas which will non show easy-to-observe colour alterations and fluctuation in colourss. The boundary lines of these amelanotic melanomas are frequently indistinct, doing ocular designation without a dermatoscope really hard. Amelanotic melanomas and melanomas arising in fair-skinned persons ( see the â€Å" Small Red Riding Hood † mark ) are really hard to observe, as they fail to demo many of the features in the ABCD regulation, interrupt the â€Å" Ugly Duckling † mark, and are really hard to separate from acne scarring, insect bites, dermatofibromas, or freckles. Following a ocular scrutiny and a dermatoscopic test, or in vivo diagnostic tools such as a confocal microscope, the physician may biopsy the leery mole. A tegument biopsy performed under local anaesthesia is frequently required to help in doing or corroborating the diagnosing and in specifying the badness of the melanoma. If the mole is malignant, the mole and an country around it need deletion. Egg-shaped excisional biopsies may take the tumour, followed by histological analysis and Breslow marking. Punch biopsies are contraindicated in suspected melanomas, for fright of seeding tumour cells and rushing the spread of the malignant cells. Entire organic structure picture taking, which involves photographic certification of every bit much organic structure surface as possible, is frequently used during followup of bad patients. The technique has been reported to enable early sensing and provides a cost-efficient attack ( being possible with the usage of any digital camera ) , but its efficaciousness has been questioned due to its inability to observe macroscopic alterations. The diagnosing method should be used in concurrence with ( and non as a replacing for ) dermoscopic imagination, with a combination of both methods looking to give highly high rates of sensing.3.14 Dermatoscopy:Dermatoscopy ( dermoscopy or epiluminescence microscopy ) is the scrutiny of skin lesions with a dermatoscope. This traditionally consists of a magnifier ( typically x10 ) , a non-polarised visible radiation beginning, a crystalline home base and a liquid medium between the instrument and the tegument, and allows review of skin lesions unobs tructed by skin surface contemplations. Modern dermatoscopes dispense with the usage of liquid medium and alternatively usage polarised visible radiation to call off out skin surface contemplations. When the images or picture cartridge holders are digitally captured or processed, the instrument can be referred to as a â€Å" digital epiluminescence dermatoscope † .3.15 Advantages of dermatographyWith physicians who are experts in the specific field of dermoscopy, the diagnostic truth for melanoma is significantly better than for those skin doctors who do non hold any specialised preparation in Dermatoscopy. Thus, with specializers trained in dermoscopy, there is considerable betterment in the sensitiveness ( sensing of melanomas ) every bit good as specificity ( per centum of non-melanomas right diagnosed as benign ) , compared with bare oculus scrutiny. The truth by Dermatoscopy was increased up to 20 % in the instance of sensitiveness and up to 10 % in the instance of speci ficity, compared with bare oculus scrutiny. By utilizing dermatoscopy the specificity is thereby increased, cut downing the frequence of unneeded surgical deletions of benign lesions.3.16 Application of dermatoscopyThe typical application of dermatoscopy is early sensing of melanoma. Digital dermatoscopy ( video dermatoscopy ) is used for supervising skin lesions leery of melanoma. Digital dermatoscopy images are stored and compared to images obtained during the patient ‘s following visit. Leery alterations in such a lesion are an indicant for deletion. Skin lesions, which appear unchanged over clip, are considered benign. Common systems for digital dermoscopy are Fotofinder, Molemax or Easyscan. Aid in the diagnosing of tegument tumours – such as basal cell carcinomas, squamous cell carcinomas, cylindromas, dermatofibromas, angiomas, seborrheic keratosis and many other common tegument tumours have classical dermatoscopic findings. Aid in the diagnosing of itchs and pubic louse. By staining the tegument with India ink, a dermatoscope can assist place the location of the touch in the tunnel, easing scraping of the scabetic tunnel. By amplifying pubic louse, it allows for rapid diagnosing of the hard to see little insects. Aid in the diagnosing of warts. By leting a doctor to visualise the construction of a wart, to separate it from maize, callouses, injury, or foreign organic structures. By analyzing warts at late phases of intervention, to guarantee that therapy is non stopped prematurely due to hard to visualise wart constructions. Aid in the diagnosing of fungous infections. To distinguish â€Å" black point † ringworm, or ringworm capitis ( fungous scalp infection ) from alopecia areata. Aid in the diagnosing of hair and scalp diseases, such as alopecia areata, female androgenic alopecia, monilethrix, Netherton syndrome and woolly hair syndrome. Dermoscopy of hair and scalp is called trichoscopy.3.17 Computer Added Diagnosis for early sensing of Skin CancerMelanoma is the most deathly assortment of skin malignant neoplastic disease. Although less common than other tegument malignant neoplastic diseases, it is responsible for the bulk of skin malignant neoplastic disease related deceases globally. Most instances are curable if detected early and several standardised testing techniques have been developed to better the early sensing rate. Such testing techniques have proven utile in clinical scenes for testing persons with a high hazard for melanoma, but there is considerable argument on their public-service corporation among big populations due to the high work load on skin doctors and the subjectiveness in the reading of the showing. In add-on to deducing a set of computing machine vision algorithms to automatize popular tegument ego scrutiny techniques, this undertaking developed a nomadic phone application that provides a pre-screening tool for persons in the general population to assist measure their hazard. No computing machine application can supply a concrete diagnosing, but it can assist inform the person and raise the general consciousness of this unsafe disease. Melanoma develops in the melanocyte tegument cells responsible for bring forthing the pigment melanin which gives the tegument, hair, and eyes their colourss. Early phases of the malignant neoplastic disease present themselves as irregular tegument lesions. Detection techniques for early phase melanoma use the morphological features of such irregular tegument lesions to sort hazard degrees.A. Skin-Self Evaluations utilizing the ABCDE methodSurveies have shown that self-performed skin scrutinies can greatly better early sensing and survivability rates of melanoma [ 112 ] . The most constituted method for skin introspections to day of the month is the â€Å" ABCDE † promoted by the American Academy of Dermatology [ 113 ] . A elaborate tutorial for carry oning skin self-exams including illustration images for each characteristic is available in [ 113 ] . The â€Å" ABCDE † trial provides a widely accepted, standardised set of lesion characteristics to analyze. The characte ristics are designed for members of the general populace, but variableness in the reading of the characteristics weakens the overall public-service corporation of the trial [ 112 ] . Preprocessing Once a exaggerated image of a skin lesion is captured it is passed to a preprocessor. The preprocessor performs planetary image binarization via Otsu ‘s method [ 114 ] . Following binarization, a affiliated constituents analysis is performed and little part remotion for both positive and negative parts removes most of the image noise. 1 ) Asymmetry A lesion is considered potentially cancerous if â€Å" one half is unlike the other half. † This counsel is comparatively obscure, so techniques developed for dermatoscopy were used for inspiration. The dissymmetry mark computation is based on the symmetricalness map technique. Symmetry maps encode a step of a part ‘s symmetricalness, known as symmetricalness metric, comparative to a scope of axes of symmetricalness defined by angle. Lesion colour and texture comparings were used to encode symmetricalness. Normally the symmetricalness metric is a map of distance R from a part ‘s centre. To cipher the symmetricalness of an image section a symmetricalness map is created for the scope of symmetricalness axes go throughing through a part ‘s centre with angles runing from 0 to 180 grades. To deduce a scalar symmetricalness mark from the symmetricalness map, the planetary upper limit is used. The symmetricalness map technique is attractive because it is able to accomplish a grade of rotational invariability via the soap operator. However, ciphering symmetricalness maps with such a high declaration in angles is computationally expensive and colour and texture can change depending on the image ‘s lighting and focal point. Lighting and focal point are non traditionally major factors in dermatoscopy but they have a big impact in macro picture taking. 2 ) Boundary line The form and strength of a part ‘s boundary line are considered jointly when measuring hazard but the machine-controlled algorithm examines merely border strength. This is because the simple cleavage techniques used were a comparatively noisy step of a lesion ‘s boundary and the cleavage noise rapidly corrupts any boundary line form metric. However, border strength is comparatively easy to calculate. The strength gradient map can besides be computed utilizing a two-stage filter combination of Sobel and Gaussian meats. Once the image gradient map is computed, the gradient magnitude values at each pel along the lesion ‘s boundary line are summed and normalized by the boundary line ‘s size to cipher the mean gradient magnitude along the lesion ‘s boundary line. This mean gradient metric signifiers the boundary line strength hazard value. In general lesions with ill defined boundary lines. Proper pick of the Gaussian smoothing meat is of import given the comparative inaccuracy of the lesion cleavage. If excessively little a meat is used, the boundary line pels may non fall straight over pels with a high gradient magnitude. To cut down variableness, all lesion images are converted to grayscale before hiting. The standard divergence of the grayscale strength values of all the pels belonging to lesion parts has to be calculated. The standard divergence value is taken as the colour fluctuation hazard. B. Image Processing for Digital Dermatoscopy and Digital Macro Photography Epiluminescence Microscopy ( ELM ) , besides known as dermatoscopy, is a noninvasive technique for bettering the early sensing of skin malignant neoplastic disease [ 115 ] . In dermatoscopy, a set of polarized light filters or oil submergence render selected cuticular beds transparent and macro lenses magnify little characteristics non seeable to the bare oculus. Most dermatoscopes besides include characteristics to command illuming and focal conditions. Dermatoscopy is often combined with digital imaging engineering and a big organic structure of research is devoted to developing computerized processing techniques runing on the digital images produced. An version of the â€Å" ABCDE † method for skin introspections to dermatoscopic images was foremost presented in 1994 [ 116 ] .3.17.1 Image Acquisition TechniquesThe first measure in adept systems used for skin review involves the acquisition of the tissue digital image. The chief techniques used for this intent are the Epilum inence microscopy ( ELM, or dermoscopy ) , transmittal negatron microscopy ( TEM ) , and the image acquisition utilizing still or video cameras. ELM is capable of supplying a more elaborate review of the surface of pigmented tegument lesions and renders the epidermis translucent, doing many cuticular characteristics become seeable. TEM, on the other manus, can uncover the typical construction of organisation of elastic webs in the corium, and therefore, is largely used for analyzing growing and suppression of melanoma through its liposomes [ 117 ] .Arecently introduced method of ELM imagination is side-transillumination ( transillumination ) . In this attack, visible radiation is directed from a pealing around the fringe of a lesion toward its centre at an angle of 45a- ¦ , organizing a practical visible radiation beginning at a focal point about 1 centimeters below the surface of the tegument, therefore doing the surface and subsurface of the skin translucent. The chief advantage of transillumination is its sensitiveness to imaging increased blood flow and vascularisation and besides to sing the subsurface pigmentation in a birthmark. This technique is used by a paradigm device, called Nevoscope, which can bring forth images that have variable sum of transillumination and cross-polarized surface light [ 118 ] , [ 119 ] . The usage of commercially available photographic cameras is besides rather common in skin lesion review systems, peculiarly for telemedicine intents [ 120 ] , [ 121 ] .However, the hapless declaration in really little tegument lesions, i.e. , lesions with diameter of less than 0.5 centimeter, and the variable light conditions are non easy handled, and hence, high-resolution devices with low-distortion lenses have to be used. In add-on, the demand for changeless image colourss ( necessary for image duplicability ) remains unsated, as it requires existent clip, automated colour standardization of the camera, i.e. , accommoda tions and corrections to run within the dynamic scope of the camera and ever mensurate the same colour regardless of the lighting conditions. The job can be addressed by utilizing picture cameras [ 122 ] that are parameterizable online and can be controlled through package ( SW ) [ 123 ] , [ 124 ] . In add-on to the latter, improper sum of submergence oil or misalignment of the picture Fieldss in the captured picture frame, due to camera motion, can do either loss or quality debasement of the skin image. Acquisition clip mistake sensing techniques has to be developed harmonizing to [ 124 ] and it is done merely in an attempt to get the better of such issues. Computed imaging ( CT ) images have besides been used [ 125 ] in order to observe melanomas and track both advancement of the disease and response to intervention.

FDG consumption has been correlated with proliferation rate, and therefore the grade of malignance of a given tumour. MRI can besides be used for tumour word picture [ 127 ] . Such methods are utilized largely for analyzing the metastatic potency of a skin melanoma and for farther appraisal. Finally, alternate techniques such multifrequency electrical electric resistance [ 128 ] or Raman spectra [ 129 ] have been proposed as possible showing methods. The electrical electric resistance of a biological stuff reflects fleeting physical belongingss of the tissue. Raman spectra are obtained by indicating a optical maser beam at a skin lesion sample. The optical maser beam excites molecules in the sample, and a scattering conseque nce is observed. These frequence displacements are maps of the type of molecules in the sample ; therefore, the Raman spectra clasp utile information on the molecular construction of the sample. Table I summarizes the most common image acquisition techniques found in literature along with the several sensing ends.3.17.2 Features for the Classification of Skin LesionsSimilarly to the traditional ocular diagnosing process, the computer-based systems look for characteristics and unite them to qualify the lesion as malignant melanoma, dysplastic birthmark, or common birthmark. The characteristics employed have to be mensurable and of high sensitiveness, i.e. , high correlativity of the characteristic with skin malignant neoplastic disease and high chance of true positive response. Furthermore, the characteristics should hold high specificity, i.e. , high chance of true negative response. Although in the typical categorization paradigm both factors are considered of import ( a trade-off expressed by maximising the country under the receiving system runing characteristic ( ROC ) curve ) , in the instance of malignant melanoma sensing, the suppression of false negatives ( i.e. , addition of true positives ) is evidently more of import. In the conventional process, the undermentioned diagnosing methods are chiefly used [ 130 ] : 1 ) ABCD regulation of dermoscopy ; 2 ) Pattern analysis ; 3 ) Menzies method ; 4 ) seven-point checklist ; and 5 ) Texture analysis. The characteristics used for each of these methods are presented in the followers. ABCD Rule: The ABCD regulation investigates the dissymmetry ( A ) , boundary line ( B ) , colour ( C ) , and differential constructions ( D ) of the lesion and defines the footing for a diagnosing by a skin doctor. To cipher the ABCD mark, the ‘Asymmetry, Border, Colors, and Dermoscopic constructions ‘ standards are assessed semi quantitatively. Each of the standards is so multiplied by a given weight factor to give a entire dermoscopy mark ( TDS ) . TDS values less than 4.75 indicate a benign melanocytic lesion, values between 4.8 and 5.45 indicate a leery lesion, and values of 5.45 or greater are extremely implicative of melanoma.A AsymmetryTo measure dissymmetry, the melanocytic lesion is bisected by two 90 ° axes that were positioned to bring forth the lowest possible dissymmetry mark. If both axes dermocopically show asymmetric contours with respect toA form, colourss and/or dermoscopic constructions, the dissymmetry mark is 2.A If there is dissymmetry on one axis merely, the mark is 1. If dissymmetry is absent with respect to both axes the mark is 0.A Boundary lineThe lesion is divided into eighths, and the pigment form is assessed. Within eachA one-eighth section, a crisp, disconnected cut-off of pigment form at the fringe receivesA a mark 1. In contrast, a gradual, indistinct cut-off within the section receives a scoreA of 0. Therefore, the maximal boundary line mark is 8, and the minimal mark is 0.A ColorSix different colourss are counted in finding the colour mark: white, ruddy, light brown, A dark brown, blue-gray, and black. For each colour nowadays, add +1 to the score.A White should be counted merely if the country is lighter than the next skin.A The maximal colour mark is 6, and the minimal mark is 1.3.18 Dermoscopic constructionsEvaluation of dermoscopic constructions focuses on 5 structural characteristics: web, structureless ( or homogenous ) countries, branched runs, points, and globules.A The presence of any characteristic consequences in a mark +1 Structureless ( or homogeneous ) countries must be larger than 10 % of the lesion to be considered present. Branched runs and points are counted merely when more than two are clearly seeable. The presence of a individual globule is sufficient for the lesion to be considered positive for globules. Asymmetry: The lesion is bisected by two axes that are positioned to bring forth the lowest dissymmetry possible in footings of boundary lines, colourss, and dermoscopic constructions. The dissymmetry is examined with regard to a point under one or more axes. The dissymmetry index is computed foremost by happening the chief axes of inactiveness of the tumour form in the image, and it is obtained by overlapping the two halves of the tumour along the chief axes of inactiveness and spliting the non-overlapping country differences of the two halves by the entire country of the tumour. Fig ( a ) Fig ( B ) : Figure: ( degree Celsius ) Figure: 3.12 ( a ) , ( B ) , ( degree Celsius ) : Calculation of symmetric matrix Boundary line: The lesion is divided into eight pie-piece sections. Figure: ( a ) Then, it is examined if there is a crisp, disconnected cutoff of pigment form at the fringe of the lesion or a gradual, indistinct cutoff. Border-based characteristics depicting the form of the lesion are so computed. In order to pull out boundary line information, image cleavage is performed. Figure: ( B ) Figure: ( C ) Fig 3.13. ( a ) , ( B ) , ( degree Celsius ) : Boundary line computation for Skin Lesion. It is considered to be a really critical measure in the whole procedure of skin lesion designation and involves the extraction of the part of involvement ( ROI ) , which is the lesion and its separation from the healthy tegument. Most usual methods are based on thresholding, part growth, and colour transmutation ( e.g. , chief constituents transform, CIELAB colour infinite and spherical co-ordinates [ 131 ] , and JSEG algorithm [ 132 ] ) . Extra methods affecting unreal intelligence Techniques like fuzzed boundary lines [ 133 ] and declaratory cognition ( melanocytic lesion images segmentation implementing by spacial dealingss based declaratory cognition ) are used for finding skin lesion characteristics. The latter methods are characterized as part attacks, because they are based on different colorization among the malignant parts and the chief boundary line. Another class of cleavage techniques is contour attacks utilizing classical border sensors ( e.g. , Sobel, Canny, etc. ) that produce a aggregation of borders go forthing the choice of the boundary up to the human perceiver. Hybrid attacks [ 134 ] usage both colour transmutation and border sensing techniques, whereas serpents or active contours 135 ] are considered the outstanding state-of-the art technique for boundary line sensing. More information sing boundary line sensing every bit good as a public presentation comparing of the aforesaid methods can be found in [ 136 ] and [ 137 ] . The most popular boundary line characteristics are the greatest diameter, the country, the boundary line abnormality, the tenuity ratio [ 138 ] , the disk shape index ( CIRC ) [ 139 ] , the discrepancy of the distance of the boundary line lesion points from the centroid location [ 140 ] , and the symmetricalness distance ( SD ) [ 133 ] . The CIRC is mathematically defined by the undermentioned equation: Where A is the surface of the examined country and P is its margin. SD calculates the mean supplanting among a figure of vertexes as the original form is transformed into a symmetric form. The symmetric form closest to the original form P is called the symmetricalness transform ( ST ) of P. The SD of an object is determined by the sum of attempt required to transform the original form into a symmetrical form, and can be calculated as follows: Apart from sing the boundary line as a contour, accent is besides placed on the characteristics that quantify the passage ( speed ) from the lesion to the tegument. Such characteristics are the minimal, maximal, mean, and discrepancy responses of the radient operator applied on the intesity image along the lesion boundary line. degree Celsius ) Color: Color belongingss inside the lesion are examined, and the figure of colourss present is determined. They may include light brown, dark brown, black, ruddy ( ruddy vascular countries are scored ) , white ( if whiter than the environing tegument ) , and slate blue. In add-on, colour texture might be used for finding the nature of melanocytic tegument lesions [ 141 ] . Typical colour images consist of the three-color channels red, green, and blue ( RGB ) . The colour characteristics are based on measurings on these colour channels or other colour channels such as cyan, magenta, yellow ( CMY ) , hue, impregnation, value ( HSV ) , Y-luminance, UV ( YUV ) chrominance constituents, or assorted combinations of them, linear or non. Additional colour characteristics are the spherical co-ordinates LAB norm and discrepancy responses for pels within the lesion [ 142 ] Color variegation may be calculated by mensurating lower limit, upper limit, norm, and standard divergences of the selected channel values and colour strength, and by mensurating chromatic differences inside the lesion. vitamin D ) Differential constructions: The figure of structural constituents present is determined, i.e. , pigment web, points ( scored if three or more are present ) , globules ( scored if two or more are present ) , structureless countries ( counted if larger than 10 % of lesion ) , and runs ( scored if three or more are present ) . 2 ) Form Analysis: The form analysis method seeks to place specific forms, which may be planetary ( reticulate, ball-shaped, sett, homogenous, starburst, parallel, and multicomponent, nonspecific ) or local ( pigment web, dots/globules/ moles [ 143 ] , runs, blue-whitish head covering, arrested development constructions, hypo-pigmentation, splodges, vascular constructions ) . 3 ) Menzies Method: The Menzies method looks for negative characteristics ( symmetricalness of form, presence of a individual colour ) and positive ( bluish-white head covering, multiple brown points, pseudopods, radial cyclosis, scar-like depigmentation, peripheral black dots/globules, multiple ( five to six ) colourss, multiple blue/gray points, broadened web ) . 4 ) Seven-Point Checklist: The seven-point checklist [ 144 ] , [ 145 ] refers to seven standards that assess chromatic features and the form and/or texture of the lesion. These standards are untypical pigment web, blue-whitish head covering, untypical vascular form, irregular runs, irregular dots/globules, irregular splodges, and arrested development constructions. Each one is considered to impact the concluding appraisal with a different weight. The dermoscopic image of a melanocytic tegument lesion is analyzed in order to grounds the presence of these standard standards ; eventually, a mark is calculated from this analysis, and if a entire mark of three or more is given, the lesion is classified as malignant, otherwise it is classified as birthmark. 5 ) Texture Analysis: Texture analysis is the effort to quantify texture impressions such as â€Å" all right, † â€Å" rough, † and â€Å" irregular † and to place, step, and use the differences between them. Textural characteristics and texture analysis methods can be slackly divided into two classs: statistical and structural. Statistical methods define texture in footings of local gray-level statistics that are changeless or easy varying over a textured part. Different textures can be discriminated by comparing the statistics computed over different subregions. Some of the most common textural characteristics are as follows. Neighboring gray-level dependance matrix ( NGLDM ) and lattice aperture wave form set ( LAWS ) are two textural attacks used for analysing and observing the pigmented web on tegument lesions. Dissimilarity, vitamin D, is a step related to contrast utilizing additive addition of weights as one moves off from the grey degree accompaniment matrix ( GLCM ) diagonal. Dissimilarity is calculated as follows: Where I is the row figure, J is the column figure, N is the entire figure of rows and columns of the GLCM matrix, and is the normalization equation in which Vi, J is the digital figure ( DN ) value of the cell I, J in the image window ( i.e. , the current gray-scale pel value ) . Angular 2nd minute ( ASM ) , which is a step related to methodicalness, where Pi, J is used as a weight to itself, is given by GLCM mean, I?i, which differs from the familiar average equation in the sense that it denotes the frequence of the happening of one pel value in combination with a certain neighbour pel value, is given by The research workers that seek to automatically place skin lesions exploit the available computational capablenesss by seeking for many of the characteristics stated earlier, every bit good as extra characteristics. 6 ) Other Features Utilized: The differential constructions as described in the ABCD method, every bit good as most of the forms that are used by the form analysis, the Menzies method, and the seven-point checklist are really seldom used for machine-controlled tegument lesion categorization, evidently due to their complexness. A fresh method presented in [ 140 ] utilizations 3-D pseudoelevated images of skin lesions that reveal extra information sing the abnormality and inhomogeneity of the examined surface. Several attempts concern mensurating the dynamicss of skin lesions [ 146 ] . The ratio of discrepancies RV in [ 147 ] has been defined as where standard divergence between yearss ( SDB2 ) is the between twenty-four hours discrepancy of the colour variable computed utilizing the mean values at each twenty-four hours of all lesion sites and topics, standard divergence intraday ( SDI2 ) is the intraday discrepancy of the colour variable estimated from the calculations at each twenty-four hours of all lesion sites and topics, and standard divergence analytical ( SDA2 ) is the discrepancy of the colour variable computed utilizing normal skin sites of all topics and times. Finally, ripple analysis has besides been used for break uping the tegument lesion image and utilizing ripple coefficients for its word picture [ 148 ] . C. Feature Selection The success of image acknowledgment depends on the right choice of the characteristics used for the categorization. The latter is a typical optimisation job, which may be resolved with heuristic schemes, greedy or familial algorithms, other computational intelligence methods, or particular schemes from statistical form acknowledgment [ e.g. , cross-validation ( XVAL ) , leave-one-out ( LOO ) method, consecutive forward drifting choice ( SFFS ) , consecutive backward drifting choice ( SBFS ) , chief constituent analysis ( PCA ) , and generalized consecutive characteristic choice ( GSFS ) ] [ 149 ] . The usage of characteristic choice algorithms is motivated by the demand for extremely precise consequences, computational grounds, and a peaking phenomenon frequently observed when classifiers are trained with a limited set of acquisition samples3.19 Skin Lesion Classification MethodsIn this subdivision, the most popular methods for skin lesion categorization are examined. The undertaking involves chiefly two stages after characteristic choice, larning and proving [ 150 ] , which are analyzed in the undermentioned paragraphs. A. Learning Phase During the learning stage, typical characteristic values are extracted from a sequence of digital images stand foring classified skin lesions. The most classical acknowledgment paradigm is statistical. Covariance matrices are computed for the discriminatory steps, normally under the multivariate Gaussian premise. Parametric discriminant maps are so determined, leting categorization of unknown lesions ( discriminant analysis ) . The major job of this attack is the demand for big acquisition samples. Nervous webs are webs of interrelated nodes composed of assorted phases that emulate some of the ascertained belongingss of biological nervous systems and pull on the analogies of adaptative biological acquisition. Learning occurs through larning over a big set of informations where the Learning algorithm iteratively adjusts the connexion weights ( synapses ) by minimising a given mistake map [ 151 ] , [ 152 ] . The support vector machine ( SVM ) is a popular algorithm for informations categorization in two categories [ 153 ] – [ 155 ] , [ 156 ] . SVMs allow the enlargement of the information provided by a learning dataset as a additive combination of a subset of the informations in the acquisition set ( support vectors ) . These vectors locate a hyper surface that separates the input informations with a really good grade of generalisation. The SVM algorithm is based on acquisition, proving, and public presentation rating, which are common stairss in every acquisition process. Learning involves optimisation of a convex cost map where there are no local lower limit to perplex the acquisition procedure. Testing is based on theoretical account rating utilizing the support vectors to sort a trial dataset. Performance rating is based on mistake rate finding as the trial dataset size tends to eternity. The adaptative wavelet-transform-based tree-structure categorization ( ADWAT ) method [ 157 ] is a specific tegument lesion image categorization technique that uses statistical analysis of the characteristic informations to happen the threshold values that optimally partitions the image-feature infinite for categorization. A known set of images is decomposed utilizing 2-D ripple transform, and the channel energies and energy ratios are used as characteristics in the statistical analysis. During the categorization stage, the tree construction of the campaigner image obtained utilizing the same decomposition algorithm is semantically compared with the tree-structure theoretical accounts of melanoma and dysplastic birthmark. A categorization variable ( CV ) is used to rate the tree construction of the campaigner image. CV is set to a value of 1 when the chief image is decomposed. The value of CV is incremented by one for every extra channel decomposed. When the algorithm decomposes a dy splastic birthmark image, merely one degree of decomposition should happen ( impart 0 ) . Therefore, for values of CV equal to 1, a campaigner image is assigned to the dysplastic nevus category. A value of CV greater than 1 indicates farther decomposition of the campaigner image, and the image is consequently assigned to the melanoma category. B. Testing Phase The public presentation of each classifier is tested utilizing an ideally big set ( i.e. , over 300 skin lesion image sets ) of manually classified images. A subset of them, for example, 80 % of the images, is used as a acquisition set, and the other 20 % of the samples is used for proving utilizing the trained classifier. The Learning and trial images are exchanged for all possible combinations to avoid prejudice in the solution. Most usual categorization public presentation appraisal in the context of melanoma sensing is the true positive fraction ( TPF ) bespeaking the fraction of malignant tegument lesions right classified as melanoma and the true negative fraction ( TNF ) bespeaking the fraction of dysplastic or nonmelanoma lesions right classified as nonmelanoma, severally [ 158 ] , [ 159 ] . A graphical representation of categorization public presentation is the ROCcurve, which displays the â€Å" trade-off † between sensitiveness ( i.e. , existent malignant lesions that are right identified as such, besides known as TPF ) and specificity ( i.e. , the proportion of benign lesions that are right identified, besides known as TNF ) that consequences from the convergence between the distribution of lesion tonss for melanoma and nevi [ 160 ] , [ 161 ] , [ 162 ] . A good classifier is one with stop ping point to 100 % sensitiveness at a threshold such that high specificity is besides obtained. The ROC for such a classifier will plot as a steeply lifting curve. When different classifiers are compared, the one whose curve rises fastest should be optimum. If sensitiveness and specificity were weighted every bit, the greater the country under the ROC curve ( AUC ) , the better the classifier is [ 163 ] .
