Race, ethnicity, prejudice: white Australia policy Essay

This paper is divided into two parts. In the first part the concepts or race, ethnicity, prejudice and racism are defined and how they are connected is discussed. Part 2 of the paper looks at the ‘White Australia’ policy and why it was introduced. The impact of such a racist immigration history on contemporary Australia is also discussed in terms of attitudes and behaviours of the population. Following is a brief discussion on how successive government policies and non-government organisations have tried to deal with and eradicate racism and discrimination against minority groups in Australia since the ‘White Australia’ policy was abolished in the 1940’s. Lastly, the tensions that remain today in multicultural Australia are explored. Part 1 What is race? During the late 18th and early 19th centuries it was thought that humans could be divided into different groups according to their biological makeup, or alternatively, their race. The term ‘race’ focused more on common features that were shared among a single species, rather than placing emphasis on the characteristics which divide us (Cohen & Kennedy, 2007; Giddens, 2001). The emerging theories of race were used to justify the rising social order as England along with other European nations became imperial powers. It was thought that there were three main race categories, white, black and yellow, with the white race being the superior race (Giddens, 2001). Today, sociologists reject the idea of racial hierarchy amongst humankind and propose that ‘race’ is â€Å"a social construct related to the ways that people and cultures interpret, and react to, minor physical differences† (Van Krieken, Habibis, Smith, Hutchins, Haralambos & Holborn, 2006, p. 264). The idea of significant biological differences has been debunked in contemporary sociology and the notion replaced with the emergence of ethnicity. What is ethnicity? The idea of ‘race’ is a social construct based on innate physical differences, while ‘ethnicity’ is purely social in meaning based on less obvious differences such as social markers of culture, language, religion, style of dress and nationality (Giddens, 2001; Cohen & Kennedy, 2007; Van Krieken et al, 2010; Matsumoto & Juang, 2004). In other words, it looks at how one group of people are distinguishable from another based on differences that are learned. In practice, ethnic labels almost always apply to minority groups within a society. This is problematic in the sense that it poses a risk of separation between ‘us’ and ‘them’ (Giddens, 2001; Van Krieken et al, 2010). Another problem is that ethnic groupings are often too generic. In Australia, for example, we might speak of a Muslim ethnic group or the Muslim community. ‘Muslim’, therefore, becomes one category which in fact holds a number of subgroups itself which does not get acknowledged. Another issue arising from ethnic grouping is that labels are usually given to the minority, when in fact, we are all ethnic regardless of if we belong to an ethnic minority or majority. What is prejudice? Prejudice â€Å"refers to opinions or attitudes held by members of one groups towards another† (Giddens, 2001, p. 250). These opinions and attitudes are usually based on preconceived views based on stereotypes rather than evidence and are hard to change even when presented with evidence stating otherwise (McConnochie, Hollinsworth & Pettman, 1988). Prejudice is based on internal beliefs and when those beliefs lead to a particular behaviour as a result it turns into discrimination. For example, if people are denied the same opportunities, such as gaining employment, based on their skin colour, their ethnicity or disability as a result of prejudice, prejudice becomes discrimination. What is racism? When we speak of race, ethnicity and prejudice we are intrinsically linking racism as well. Racism is prejudice taken another step further. In contrast to prejudice, racism is based on perceived cultural superiority, which is itself based on perceived genetic superiority (McConnochie et al, 1988). There are two forms of racism: individual and institutional. Individual racism involves one-on-one scenarios where racist attitudes are expressed based on a particular individuals belief towards another. For example, one person might be of the opinion that all Aboriginal’s are dirty, and therefore, be racist to an Aboriginal when they are walking down the street, at school or work. Institutional racism on the other hand is far broader in context and more complex. It refers to the ways in which racism has infiltrated into social institutions which govern, discriminate and oppress various groups within that society based on their race (McConnochie et al, 1988). These institutions within our societies, such as schools and healthcare services, use racism in a systematic manner which favours one group over all the others. Although racism as a notion is the same for both individual and institutional purposes, the consequences of the two are vastly different. Sociologists have argued that in the recent years racism has shifted from excluding groups on a biological basis, to more of a cultural basis of difference (Giddens, 2001; Van Krieken et al, 2010). In this new wave of racism there are clearly underlying political dimensions. Part 2 The White Australia Policy (1880’s – 1940’s) Australia as we know it today is a result of careful political planning and construction to create a particular kind of society. From early European settlers until the late 19th century Australia had an open immigration policy (Cope, Castles & Kalantzis, 1991). Everyone was welcome and encouraged to come as populating the land was the primary concern. However, immigration legislation changed as unemployment rates started rising and fears of over population from the Chinese was ignited. As a result, the White Australia policy was introduced in 1980 and lasted through to early 1940’s (Van Krieken et al, 2010; Jupp, 2002). Economic and cultural reasons were the main reasons for introducing the White Australia policy (Windschuttle, 2005). Social cohesion was a real concern at the time and it was believed that solidarity could not be maintained with so many ‘inferior’ races populating the nation. It was believed that, in accordance to Darwin’s theory of evolution, the fittest race will survive and the weakest would be eliminated accordingly. These were the main underlying rationales for keeping Australia as ‘pure’ as possible. Impact of Australia’s Immigration history on the attitudes and behaviours of contemporary Australians As contemporary Australia becomes more diverse, racist attitudes embedded from immigration history and previous policies can still be felt. Expression of racism through attitudes and behaviours has taken on new form. Contemporary expressions of racism tend to be focused on national identity and nationhood rather than genetic superiority, and tend to also be fuelled by the popular media. Once again, the concern appears to be on social cohesion and the belief that minority groups place the cohesion and national identity at risk, showing remnants of the White Australia policy. Inherent racist beliefs and attitudes expressed today are targeted towards minority groups who potentially are the most disadvantaged. Measures taken by the government to address this disadvantage is seen as an unfair privileged treatment at the expense of the majority. Examples of this include opposition towards action policies promoting Indigenous Australians into certain jobs and provision of English language support to newcomers. Attempts at eradicating racism and discrimination against minority groups and individuals since the end of the White Australia policy Assimilation lasted from the 1940’s until the mid 1960’s. This new policy adopted the assumptions from the White Australia policy on preserving the society as homogenous in order to keep cohesion and harmoniousness. It meant that immigrants should absorb themselves into mainstream culture as quickly as possible and become as ‘Australian’ as possible (Van Krieken et al, 2010; Cope et al, 1991). Government policies were put into place for English language lessons, which were at the centre of the policy, along with services to help migrants find employment and help them out with housing upon their arrival (Van Krieken et al, 2010). In other words, the main emphasis of the assimilation policy was to make ‘them’ look like ‘us’ as much and as quickly as possible. Integration followed on from assimilation and lasted from the mid 1960’s to the early 1970’s. The expectations of the assimilation policy and the evident reality were rather different and as a result the integration approach appeared. The government shifted focus from making ‘them’ like ‘us’ to educating the Australian public to accept and welcome the new changes and the need to change attitudes to be less fearful and negative to more tolerant. With new policies developed at the time, overall differences were welcomed and encouraged into the public domain. By the early to mid 1970’s multiculturalism was introduced as an attempt to ease some of the tensions and anxieties and started the shift from British focused immigration. The Racial Discrimination Act was introduced in 1975 and racism was officially legislated against. Under the new RDA it became against the law to discriminate in areas such as housing, employment and provision of services. By the 1980’s, multiculturalism was being redefined, and the emphasis of the concept was equity across the board for all individuals in Australia irrespective of their background (Van Krieken et al, 2010). Multiculturalism was a concept encompassing the need for unity, inclusion, tolerance, acceptance and equality. What tensions remain today in multicultural Australia? Despite the push by the government for all residents to identify as an Australian and work together to develop a national identity, whilst providing equal opportunities and access across the board, it hasn’t been an easy journey to date. At the core of the issue of Australia as a multicultural nation is national identity. Defining what it means to be ‘Australian’ has been problematic over the years and has usually reflected political movements. Remnants of White Australia policy can still, however, be felt in today’s society as they are expressed through traditional racist attitudes and beliefs and are sometimes the cause of racial attacks, segregation and anxiety of minority groups. Moreover, tension exists on a number of other issues including the feeling of displacement for migrants of non-English-speaking background who after some time do not identify with the Australian national identity nor with their mother-land (Jupp, 2002). They face a number of adjustment issues as well such as struggling to gain employment. Other issues still relevant in multicultural Australia include limited inclusion of Indigenous issues within the policies, tension in relation to Asian immigration, the extent to which different value and belief systems are accepted and allowed for, the uncertainty of the role and nature of ethnic and minority groups within the broader mainstream society, the correlation of class, gender and ethnicity, the conflict between inclusion and tolerance and the currently hot debated issue on asylum seekers (Jupp, 2002; Van Krieken et al, 2010). In conclusion, whilst multiculturalism has certainly been a step forward and progressive thus far in unifying all Australian citizens as one there is still a long way to go before the ideal is achieved. More research is needed in areas that affect minority groups and the daily issues they are faced with based on their gender, age and ethnicity. The findings need to be considered and used when in writing new policies for the nation. While there is no easy answer to any of the issues Australia is faced with today, a new form of multiculturalism with an even bigger focus on unity, respect and mindfulness is needed in progressing forward.

Critique of the Ramayana Modern Prose Translation Essay

In a just world, Mr. R. K. Narayan’s estate would be responsible for reimbursing seventeen-fifty, plus applicable taxes, to all those who purchased the Penguin Classics 2006 publication of his book, The Ramayana: A Shortened Modern Prose Version of the Indian Epic. Stated clearly on the back of the cover is the promise that R. K. Narayan â€Å"recounts [The Ramayana] with the narrative flair of a master novelist’’. The back cover lied. Narayan’s re-telling condenses the epic poem so much to the point of nearly listing a series of events. No matter the inspiration, Narayan’s The Ramayana is still a story, and should therefore be able to stand on it’s own as a captivating tale—with further literary research or expansion being used to enhance it’s appeal, not explain it. Arguably, the ‘narrative flair’ of this re-telling is little more expressive than unsolicited summaries found on the Internet, and without further literary aide or instruction, does not stand as a solid piece of literature. What is worse, is that instead of allowing a greater breadth of readers to relate and experience tale of the Ramayana, new readers are alienated by it’s convoluted atmosphere. While the task is grand, Narayan’s translation is not listed as an aide to a larger, more in-depth version; it is still a novel and as such needs to be able to stand strong in its own right when evaluated alone. People who have no prior knowledge of the original Sanskrit story, and who have not been raised with the Hindu epic as a part of their life, should be able to pick up this book, read it, and—regardless of how far the tale may go in global history—be able to enjoy one hundred and fifty one pages of literature, without having any prior knowledge, or requiring further research. Having more knowledge, and doing more research on the original epic tale should increase what readers are able to receive from the book, but it should not be necessary in order to understand it. As it stands, without knowing the original tale, new readers are left with very little literary flow and a patchy depiction of what is supposed to be a lush world. At one point, while Bharatha and Rama argue as to who should be the rightful king, their entire episode is related with: â€Å" The argument went on at a highly academic and philosophical level, the entire assembly watching with respect. (Narayan 60) That assertion does not express a deep academic and philosophical argument, but rather states that one was occurring; the reader doesn’t get to experience what transpired between the brothers, or garner any emotion from it. It goes on to almost quite literally depict the event with a he-said/he-said monotony: So be it; if I have the authority—then I confer it on you as the ruler,† said Bharatha at one stage. â€Å"On my command as the ruler, if you desire to think so, you shall be the King. † It went on thus. Rama went on repeating that there could be no word higher than that of a father; no conduct other than obedience to it. Throughout he referred to Kaikeyi in the gentlest terms and always as â€Å"mother†. (Narayan 61) The listed manner in which the plot is unfolded by Narayan’s re-telling is barely more narrative as a piece of literature than an excerpt from that of the free online encyclopedia Wikipedia: Bharatha refuses to profit from his mother’s wicked scheming and visits Rama in the forest. He requests Rama to return and rule. But Rama, determined to carry out his father’s orders to the letter, refuses to return before the period of exile. However, Bharatha carries Rama’s sandals, and keeps them on the throne, while he rules as Rama’s regent. (Wikipedia Contributors) There is very little more efficiency or flair in Narayan’s telling, and in fact, Wikipedia depicts the stages of the long tale with better clarity; if the prose is not going to be linguistically lush and evocative, it may as well be clear (Wikipedia is not only clear, but free of charge as well). It is of course not a simple task to undertake translating an epic poem from a rhythmic language, into prose with a language devoid of the same musicality. However, to the novice reader of The Ramayana, they would not know the difficulty of the task, and thus—however harsh it may seem— should not be a factor in the reviewing of the story as it stands alone. Narayan was by no means an incapable writer, and as winner of numerous awards and accolades—not the least of which being multiple nominations for the Nobel Prize in Literature (Rajnish Wattas), he does not need defending that he has great ability as a writer, yet the bottom line remain that when it is stripped of further discussion, research, and introductions, The Ramayana: A Shortened Modern Prose Version of the Indian Epic just does not stand on it’s own as captivating modern prose. With nearly each new episode of the tale, Narayan prefaces the action with even more listed information, take for example the introduction to the chapter of Vali: The characters in the drama that follows are Vali, Sugreeva, Hanuman, and Rama. The action takes place in the mountainous forest regions of Kiskinda, a kingdom ruled and inhabited by monkeys. In the Ramayana, the articipants are not only human beings, but many others from God’s creation, intelligent, cultured and with their own achievements of spirit as well as physique: Jambavan was a bear, Jatayu was an eagle, Lakshmana—Rama’s brother—was himself a human incarnation of the Great Serpent Adisesha in whose coils Vishnu rested. (Narayan 90) Again, the story is told by listing statements of what is going on. As with the landscape, and even the characters themselves, nothing is depicted in the story-writing of the prose, but stated, as if the entire epic was a news article being reported by Narayan, as opposed to a vivid history with grand escapades and extreme characters. By translating an epic tale from poetic verse into shortened modern prose, the objective is ultimately to enable a broader audience to relate to and appreciate a classic tale. Poetry is a secluded literary world that does not have the mass appeal that modern prose does; yet Narayan’s re-telling is too constrained and overwhelmed by the amount of story condensed into it. By trying to constrain the length of the story to allow for more readers to get through it, Narayan’s ‘master narrative flair’ seems lost, and the epic tale is a heavy list of events that merely occur on the page.

Children Literature Essay

No one can explain the literally unprecedented Harry Potter phenomenon, starting with J. K. Rowling, now 35, whose life has been changed utterly by the product of her imagination. Seven years ago, she was the single mother of a small daughter, living in a two-room flat in Edinburgh, listening to mice skittering behind walls. Now she is internationally famous and earning, according to various estimates, somewhere in the range of $30 million to $40 million a year. Once, during a bad patch, she dreaded the hostile looks she would attract while lining up at the local post office to claim her weekly income support check. Now however she still gets lots of stares, but in the reverse order (Neil 45). Yes, it true J. K. Rowling life has chanced and her books has been the hottest commodity for commercialization since forever. THESIS: There has been a lot of controversy regarding the Harry Potter book series, the scope of the controversy range in conversations from schools, churches, board rooms, colleges and universities. Some of the discussions have been positive and some negative, but mostly what everyone is saying is that the Harry Potter book series will become a classic, because when compared to other children literature books they are just good or better than most, if not all of the other children’s books. In this essay I will prove the point that the Harry Potter books have all that it takes to become part of the literary canon. I will compare the Potter books to five children literature books to determine their literary authentic. I will look at the Potter books from a Philosophy prospective to give a clear concept about the books. I will compare opinions of lay persons, and scholars, and lastly I will discuss the affects that commercialization have had on the books. The books that I have chosen to compare the Potter books are: â€Å"The Chronicles of Narnia,† â€Å"Alice in Wonderland,† and Through the Looking Glass,† Hackberry Finn,† and â€Å"the Wizard of Oz, I have chosen these five books to compare to the Potter books, because these books are books that have endured for centuries. First I will compare the Harry Potter books with â€Å"The Chronicles of Narnia†. The Chronicles of Narnia is a series of seven fantasy novels written by C. S. Lewis. They are considered classis of children’s literature and are perhaps the author’s best known work. The books that make up the Chronicles of Narnia consist of The Lion, the Witch and the Wardrobe, Prince Caspian, The Voyage of the Trader, The Silver Chair, the Magician’s Nephew, and The Battle. The Chronicles of Narnia are great children literature books because they contains Christian themes, â€Å"These books may also be used to teach children about spirituality, and are often times viewed as religious allegories. These books teach child about good verse evil, and at the time of their publication they were very popular books, and still are today. Like the Chronicles of Narnia, the Harry Potter books also teach children about good verse evil. But these books like the Potter books have had plenty of criticism. There were certain Christians and Christian organizations who felt that The Chronicles of Narnia promotes ‘soft sell paganism and occultism†, because of the recurring pagan themes and the supposedly heretical depictions of Christ as an anthropomorphic lion. Satyrs, fauns, centaurs, dwarves, werewolves, giants, and even the pagan god Bacchus and the Maenads are depicted in a positive light, when they are distinctly pagan motifs (Smith 10). Although, there was all this criticism about the Chronicles it wasn’t enough to prevent these books from becoming classic. Secondly, Alice’s Adventures in Wonderland is a great children literature book. This book is considered one of the first books created solely to amuse children. It is witty, playful, full of clever conceits and genuine comedy and downright entertaining. But what makes it better than the Harry Potter books? Or is it? No! The Harry Potter books are witty, with genuine comedy, full of clever conceits and downright entertaining, also the Harry Potter books are read by children, young adults, and adults as well. Even children who as a rule are skeptical of reading are reading the Harry Potter books. Should this alone be reason enough to allow the Harry Potter books to classify as a classic? I think so, but let’s continue with our comparison of the other children books (Carol 3-10). The third comparison to the Harry Potter books will be Lewis Carol’s Through the Looking Glass. Just like Alice’s Adventures in Wonderland, Through the Looking Glass is a great children’s story. This book is a continuation of the story of Alice in Wonderland, and over the years it has amused and entertained many children, but what makes its better than Harry Potter? Is it really better than Harry? Before we answer the question lets continue with our comparison of the next book (Carol 6-10). The fourth comparison will be The â€Å"Adventures of Huckleberry Finn. In this novel a young boy is in search of freedom and courage. I believe that this book became a classic because it was one of the first American books in which a black character is portrayed as someone to be emulated, in this case serving as the voice of reason for a cast-off urchin and a middle class white boy. There was plenty of criticism about this book, because it used the word â€Å"nigger† throughout. Many people feel that the word’s racist and discriminatory connotations make it unacceptable to use any where, and particularly in a book aimed at child. Others, however, claim that to call the book racist because of this usage is to miss its point. Again, â€Å"The Adventures of huckleberry Finn is a very nice story, full of fantasy, but it has nothing that the Harry Potter is missing. The fifth comparisons will be the Wizard of Oz. The Wizard of Oz, created the popular political fable rather than having Christian inspiration uplift, with a protagonist who is an admirable, individualistic, and rather selfish child rather than a cooperative do-gooder. However, Baum at the same time retained the dominant structure of nineteenth (twentieth century fantasy and with it the neo imperialism that assumed the inherent superiority of certain racial types. The Wizard of Oz is a great children literature with lots of fantasy (Baum 28). Development of fantasy itself owes a great deal to children’s literature, but this does not mean that fantasy is only for children. However, the Harry Potter books have made it trendy to ready fantasy again, but I think it’s worth reminding ourselves of the great tradition that preceded Rowling’s books and helped children to grow up realizing that it is okay to be imaginative and to continue to dream. The Harry Potter books have all the fantasy and intrigue as all the other books and more beside. Each of the books that I have named were usually books that were read by adults to children as a bedtime story, where as the Harry Potter books are being used for the same purpose and more. Not only are parents reading the Potter books to their child as bedtime stories, but in addition they are reading them, themselves for the sake of getting lost and carried away in the magical world of Harry Potter.

Global Leader in Foreign Direct Investments Essay

This dissertation focused on the Foreign Direct Investments (FDI) of India relative to China, together with its competitive advantages and the underlying factors which set them apart. In addition, strategies in which India can further strengthen its competitive advantage were elaborated together with the best approaches to keep at par or surpass China in terms of its FDI dominance. This chapter presented the background of the research problem, the research questions that the dissertation aimed to answer, significance of the study, the dissertation’s adopted research design and methodology, together in which how the sections in this dissertation were organized. 1. 1 Background of the Problem The surge of foreign direct investments in Asian countries is primarily determined by the privatization and at the same time the globalization of production. The degree of political stability, government policies, together with trade and investment regimes allowed host countries to be very open in terms of FDI investments. Due to the liberalization of the developing countries’ economies, the Global Development Finance of the World Bank in 1999 claimed that FDI flows to developing countries have increased more than six times (Chakraborty and Basu, 2002). Foreign direct investments have bloomed for both China and India by more than 1,500 percent between 1990 and in the recent years, and both countries have growing domestic considerable consumer markets, both economies are starting to produce higher value products and develop networks to maintain competitive advantages beyond mere cost (Laudiciana and White, 2005). Both India and China share the same level of competitiveness in terms of FDI attractiveness among multinational companies. However, it could be noted that India or China being a more favorable destination for FDIs should be closely taken into consideration. It could be noted that there are business ventures that are proven to be more profitable exclusively in only one of the countries even though the aforementioned offers the same services. On another perspective, specific business ventures could experience a relatively highly specialized output given for instance that such would be deployed in the right geographic location (Laudiciana and White, 2005). It could be noted that India has undergone remarkable international integration and development over the past few years. Since 1991, after the external payment crisis in India, there has been liberalization of various policies implemented by the government. In turn, the current investment climate has attracted many foreign investors in the country in various sectors. As such it is with this respect that competitive advantages possessed both by India with China, could be noted as it plays a vital role in terms of the success and eventually business profitability. On the other hand, it could be traced back that China started its state-led modernization reform in the late 1970s after many years of operating according to the Soviet model. Contrasting this to India, the aforementioned’s main reform started after 1991 after which relied largely on the private sector. China’s FDI mainly consists of capital intensive flows whereas India’s FDI is mainly skill intensive (Laudiciana and White, 2005). The impact of such investment has on the domestic economy and the experience of the multinationals with the overall business environment in the sub continent is very vital. Thus it becomes necessary to study the impact of such inflows as it has important policy implications. 1. 2 Research Questions The dissertation aims to answer the following questions: 1. What are the factors that differentiate India’s and China’s FDI performances that influence the inflows and stocks of the aforementioned? 2. What are the effects of FDI inflows and stocks to the economy of India? 3. How will India develop a competitive advantage in terms of its FDI and take over China as a leader in FDI in the future?

Found Dog Flyer Essay

According 2013 IPCC Status Report on Climate Change, climate change is occurring due to global warming. Observational evidence is coming back from all continents and most oceans, And it shows that many natural systems are being affected by regional climate changes particularly temperature increases. There is much scientific data backing the (intergovernmental panel on climate change) with conclusions and facts, based on changes in weather patterns (increasing temperatures, changes in snow and ice including, permafrost) also according to findings there is a high confidence that natural water systems, are also affected including, enlargement and increased numbers of glacial lakes, settlements in mountain regions are at high risk of outburst floods caused by melting glaciers. Governmental institutions in some areas are responding to the problems caused by global climate changes by building drainage networks and dams. The climate changes also lead to increasing volatility in storms and wild fires, droughts, and reduced energy demand’s and increasing sea levels. The aspects of climate change we are certain of are as follows, increased water availability in moist tropics and high latitudes, and decreasing water availability and increasing drought in mid-latitudes and semi-arid low latitudes, hundreds of millions of people exposed to increased water stress causing localized negative impacts on small business and coastal areas, and increased damage from floods and storms, and leading to erosion in coastal areas in addition based on satellite observations since the early 1980s there is high confidence that there has been a trend in many regions towards earlier â€Å"greening† ( measured by the normalized difference vegetation index) Of vegetation in the spring linked to longer thermal growing seasons due to recent warming. About which we are uncertain is many of the long term effects of climate change. The main factors determining climate change are carbon dioxide and pH levels in the environment, and are mainly a result of human activity with factors  such as carbon emissions. The report states phenomenon and directions of trends and, passes assumptions based on past trends are believed to wide spread effects on water systems but not limited to in addition to food and water shortages, increased death food and water borne diseases and wide spread erosion. Many assumptions are made based solely on passed trends I feel some of are inconclusive due to the lack of data in the report to support. And in conclusion This is my first time in a college class like this and everything is new to me and I need a lot more research to draw any more conclusions, and I am uncertain of information that is missing to support more of the causes.

Assignment 2 - Essay Example Assessing the risk comprehensively includes evaluating the total magnitude and likelihood of the potentiality of losses, and also offers a full understanding, of the roots and impact of these losses (Kevin, n.d.). A comprehensive risk assessment involves the following steps: 1. Setting and understanding the context. It involves articulating the objectives and the parameters of the institution considers when managing risks. This is assesses the current situation, needs gaps and evaluates what already exists, to build on the capacity and avoid duplication of efforts. This is carried out through a systematic inventory and evaluation of the already existing risk assessment studies and the available data (FIRESCOPE, 1994). 2. Hazard identification This involves finding the type, location, intensity, and likelihood of threats and risks prevalent in a given community. 3. Evaluating exposure This identifies the population and the property that is at risk and demarcates disaster prone areas. 4. Analysis of vulnerability This determines the capacity of the elements in a given community at risk to withstand the risk conditions. 5. Impact analysis This outlines the estimation of potential losses of the exposed population, property, livelihood, environment and the economy. 6. Profiling the risk This evaluates the various cost effective risk reduction options available, in terms of the ability of the community in risk reduction and its socio-economic concerns. 7. Formulation and revisions of action strategies and plans. This involves setting priorities, allocation of resources (both human and financial) and initiating relevant programmes. The all hazards approach entails inclusion of all the possible types of risk or threat in risk assessment. It aims to include all the types of risk, irrespective of the source, to give a standardized overview guided by a set of principles and steps. It’s a comprehensive and integrated means of assessing threats and risks. Assessing r isks using the all hazards approach in an integrated way significantly reduces the vulnerability of people, property, environment and the economy (Service, 2010). Question 2 Business continuity refers to the ability of an organization to provide support and service to its clients and its ability to keep up its viability before, during and after a business continuity occurrence. It’s a holistic management approach that recognizes the potential impact that would threaten the firm and it offers a framework of building the capacity and resilience for an effective response so as to safeguard its interests. Although it may be more practical for large businesses, it is very important to maintain full functioning throughout a disaster crisis. Business continuity plans also outlines the basic concerns like the leadership command in an event a company leader dies or is really ill. They also address backup plans for drastic scenarios such as patent lawsuits, labour disputes, or bottlene cks distortions. This allows the leaders to review the threats and weaknesses to their organization from a detached point of view.

Financial Accounting Assignment Example | Topics and Well Written Essays - 1000 words

Financial Accounting - Assignment Example Although the companys liquidity position has improved from 2010 to 2012, the company should take further measures to improve its liquidity positions so that the short term obligations can be paid of whenever they are due. The profitability ratios are used to gauge the overall profitability of a company relative to its level of sales. The operating profit margin of the company registered an increase from 27.47% in 2010 to 31.98% in 2012. The operating profit increased on account of considerable decrease in the unusual expenses of the company. This shows that the overall operational efficiency of the company has not improved and the increase in operating margin is the result of a decrease in unusual expenses of the company. Profit margin of the company witnessed a considerable increase from 11.09% in 2010 to 18.22% in 2012. The increase in operating profits of the company translated into better net profit of the company. Return on assets and return on equity of the company also showed signs of improvement on the back of an increase in the companys overall net income. BEP ratio remained relatively stable in 2012 at 10.37% as compared to 10.49% in 2011. The debt management ratios helps in assessing the mix of companys debt relative to equity.

Everybody is born, everybody dies, everybody needs to be loved, and to love. These are just a few of the human experiences that are common to men and which are usually portrayed in theaters, bringing to life what some might run away from, get obsessed with or would not just mind at all. In such cases, the theater can serve as an encouragement for me at times I am undergoing sufferings and think that I am not able to rise from a sorry state; or an awakening call when I am bound to engage in things that are morally unacceptable.

Portfolio Essay Example | Topics and Well Written Essays - 2000 words - 6

Portfolio - Essay Example Japan has become one of the industrialised countries to some extent (Cusumano, 2013). The pillar Japanese industries like housing and the auto industry are developing in leaps and bounds. The main exported products in Japan are electric and machinery equipment and the most imported products are the raw materials used in industries. Because of economic extroversion, the industry of Japan has internationally competed in the recent years and as a result, the industrial development in the country is highly influenced by global economic environments (Cusumano, 2006). The price of exports in Japan keeps on declining thus making it more challenging than other sectors. Foreign-invested enterprises and products’ market share, on the other hand, keep on increasing. These two factors increase the challenges that the domestic industry of Japan faces based on production and selling (Krafcik, 2008).For instance, the domestic enterprises are affected particularly. In addition, industries such as light and textile have decreased their growth rate since the year 1990. Additionally, the production rate of products such as durable consumption goods has drastically decreased.The main dominant sector in the economic status of Japan remains its industries and manufacturing sectors. Despite decreasing the nation’s GDP by 5% percent, industrialization still remains the leading sector and has contributed to 55 percent of the country’s GDP in the year 2012 (Lieberman, Lau & Williams, 2000). This cemented the position of Japan as among the leadin g country in terms of industrial output. The industrial sector in Japan has not only increased the economic growth of the country, but also increased the rate of employment opportunities. More factories are being opened day by day in Japan, thus creating both professional and non-professional employment opportunities. Industrial development

Buddhism Essay Example | Topics and Well Written Essays - 750 words - 5

Buddhism - Essay Example cess, went into a long period of contemplative meditation, received enlightenment and from thence came to be called The Buddha or the enlightened one. He passed on the knowledge to his followers through teachings based on four major tenets. The Buddha taught the four noble truths as i) the world is full of sorrow ii) desires are the main reason for sorrow iii) sorrow can be overcome by killing desires and iv) desires can be killed by following the eight-fold righteous path (Rahula, p.45). In this way the Buddha taught us the means to overcome sorrow, lead blissful life and ultimately attain Nirvana. The principle of righteous living differentiated Buddhism from the other major contemporary religions in the Indian subcontinent viz., Hinduism and Jainism, and impresses me as the most important of the Buddha teachings. The concept of middle path or magga taught by the Buddha as the most appropriate path to overcome sorrows has relevance for everyone and all times. It negates the other two extreme paths (of seeking worldly pleasures or practicing penance) since both have failed to eliminate sorrow from life on the one hand and can not stand the test of scrutiny as the solution for humanity’s problems (Rahula, p.92). The Buddha taught us to follow the middle path by practicing the eight-fold righteous living viz., right understanding (belief), right thought, right speech, right action, right livelihood, right effort, right mindfulness (recollection), and right concentration (meditation). As Rahula mentions in his book, ‘†¦they are all linked together and should be practiced simultaneously according to a person’s capacity’ (p.46). Together they constitute the essence of ethical and moral conduct. The context for conduct arises out of one’s day-to-day life and the never ending hankering after desires. Continuity of life or existence is termed as Samsara in the Buddhist tradition (pp. 48 & 60) and Samsaracakra as the cycle of life, death and rebirth,

Week 3 Essay Example | Topics and Well Written Essays - 250 words - 3

Week 3 - Essay Example In a large enterprise, tracking the use of these resources helps in the effective allocation of costs as per the departments. In the end, an organization is able to understand how its network resources are used and how they are paid for. Thirdly, a good reference model plays an important role in the configuration management. This mainly involves understanding the configurations of the devices and network (Nuangjamnong, et al, 2008). This is helpful when adding new components onto the network or when distributing resources to increase capacity. For an enterprise, proper configuration management promotes effective use of the network in undertaking business activities. Forth, the reference model will help in promoting security management. Specifically, the reference model helps in the authentication and authorization processes, thereby controlling who accesses the network. In addition, the reference model plays a role on protecting the security and integrity of the data on the network (Nuangjamnong, et al, 2008). This is important for most enterprises because loss of data or breach of security could have devastating effects to the operations. Finally, having a good reference model ensures that the network management system effectively monitors performance of the network. The organization is thus able to satisfy the needs of all the users with minimum failures and interruptions. Enterprises need to have all the relevant units served effectively in order to enhance the operations within the organization. Nuangjamnong, C. , Maj, S. P., & Veal, D. R. (2008).

Augustus from Prima Porta Essay Example | Topics and Well Written Essays - 500 words

Augustus from Prima Porta - Essay Example "The posture is that of a victorious general addressing his troops, and the emperor is shown in armor. His breastplate is sculpted with scenes of Roman military triumph and the mythological figures of gods and goddesses. The pose of the figure is clearly based on the Greek model of the Spear Carrier, and the face shown is that of a handsome man in the prime of life." (Lewis and Lewis, 230) Through an effective combination of Greek idealization and Roman realism, this marble statue creates a convincing portrait of a 'real man' and a successful image of the perfect leader. Augustus is represented in this statue as the 'pater patriae', who is looking down on his people with calm concern and complete self confidence. Therefore, it is essential to realize that Augustus of Prima Porta, which is now displayed in the Braccio Nuovo of the Vatican Museums, is a perfect example of the Imperial Roman statuary and Augustus, in this statue, consciously attempts to identify himself with the ultimat e authority of Rome during the Golden Age of the Roman civilization. In a reflective analysis of Augustus of Prima Porta, it becomes lucid that this statue of the emperor Augustus can rightly be considered one of the most essential examples of the enigmatic works of art from the Augustan era.

Media Law Essay Example | Topics and Well Written Essays - 5000 words

Media Law - Essay Example Moreover, if a judge excludes evidence because its probative value is outweighed by its prejudicial effect, and that evidence is reported in the media, can the defendant have a fair trial? All indications are that balancing these competing rights in the UK appears to favour the right to a fair trial over the freedom of expression accorded the media.4 Essentially, there are strict rules and laws in the UK relative to the publicity of a trial and constraints on the media so as to preserve the integrity of trial process.5 Essentially, the UK attempts to ensure that all restrictions on media reporting is limited so as to preserve the integrity of the judicial process so that constraints on freedom of expression by the media are proportionate to the ends of justice.6 This paper examines the way in which the UK’s legislature and judiciary attempts to balance or more especially fails to balance the tensions that arise in the application of the principles embodied in both the right to a fair trial and freedom of expression via the media. ... The final part of this paper will provide an analysis of case studies demonstrative of why the law attempt to balance the right to a fair trial with the media’s right to freedom of expression. In the final analysis, the legal framework for balances these tensions are ultimately aimed at preventing a trial in the media and ensuring that the issue of guild and innocence is determined in the court room, free of media influence and/or manipulation. I. Overview of the Right to a Fair Trial and Freedom of Expression via the Media A. Freedom of Expression By virtue of the UK’s Human Rights Act 1988, the European Convention on Human Rights (ECHR) was implemented and came into force in 2000.7 Although Article 10(1) of ECHR provides for freedom of expression, Article 10(2) goes on to ensure that freedom of expression is no an absolute right. Specifically, Article 10(2) cautions that freedom of expression â€Å"carries with it other duties and responsibilities† and therefor e: May be subject to such formalities, conditions, restrictions or penalties as are prescribed by law and are necessary in a democratic society, in the interests of national security, territorial integrity, or public safety, for the prevention of disorder or crime, for the protection of health or morals, for the protection of the reputation or rights of others, for preventing the disclosure of information received in confidence, or for maintaining the authority and impartiality of the judiciary.8 Maintaining the authority and impartiality of the judiciary can be seen as the most important constraint on the freedom of expression in the context of the right to a fair trial. This is especially so in

Computer laws in US. Computer Fraud and Abuse Act Research Paper

Computer laws in US. Computer Fraud and Abuse Act - Research Paper Example Just like any other invention, computers have two sides; the positive and the negative side. The positive side is where business flourish, scientists do more invention and government offer better services while on the other hand, it gives criminals an extra tool to commit more crimes and get away with it. Computer crimes have been on rapid increase since the advent of intern. Internet has facilitated the criminal activities as a means of access other people’s computers regardless of geographical location. Crimes such as cyber-stalking, child pornography, fraud and scams, hacking copyright violations, malicious code are some of the computer crimes that are now easily committed because of the internet. Compute crimes are unavoidable to organizations that use IT in delivering their services and products. Computer professional therefore should ensure that there are frameworks put in place to protect and face these challenges through laws. This paper will identify and detail some o f the computer laws put in place by US federal legislation. Computer laws face greater challenge because of the dynamic nature of computer crimes because of the new and evolving technologies. The wire fraud statute was the first law in the US used to prosecute computer criminals. This law prohibited the use of communication wires that are used in the international commerce with an attempt to commit a fraud. This law is still in place and is used to date to prosecute computer criminals.... The challenges with the initial structure of CFAAA was that to successfully prosecute fraud charges, one must provide evidence that the suspect gained unauthorized access into the computer system (CFAA, 1986). Have a clause that touched on the method of entry into the computer system rather than focusing on the computer usage was a loophole for crimes committed by insiders. An employee within the company who has legal access to the computer can also commit a crime using the computer. Since it will not be proved that he/she had illegal access, then such person will not be prosecuted. CFAA was modified for the second time in 1994 so as to deal with the act of malicious code such as viruses, worms and other programs designed with an aim of changing or damaging data on the computer (Title 18 U.S.C section 1030). This amendments enhanced the law because initially it focused on the access to the computer system without looking at how the computer system was used. The law was now able to pr osecute those who executed illegal or malicious programs on computers with indention of causing damage to data or the computer. There are several acts that have been passed to add strength or deal with loopholes in CFAA. The National Information Act (NIIA) was enacted in 1996 to protect computer systems against those who access them using other people’s authorization. Penalties under CFAA Offense Minimum sentence Maximum sentence Getting national security information 10 year 20 years Unauthorized access in government computer 1 year 10 years Knowing access and damage 1 year 10 years Knowing access and reckless damage 5 years 20 years Trafficking in passwords 1 year 10 years Extortion involving threats of damage computer 5 years 10 years Theofel v. Farey-Jones in 2003 is a

Management and Information Systems Individual Portfolio Report Essay

Management and Information Systems Individual Portfolio Report - Essay Example First, the contribution of each project to the achievement of the portfolio is considered to justify the adoption of the portfolio. Secondly, the manager examines the performance effectiveness of each project in the portfolio. Thirdly, the developer of the portfolio reviews the negative impact of the project on the performance of other projects in the company (Fritz and Schiefer, 2009). Finally, the manager contemplates the dependent and independent projects in a specific portfolio. Ginsters Company operates in a demanding market due to the increased competition in the region. In addition, the company’s operation costs tend to increase because of the long distribution chain. Development of a reliable and appropriate management portfolio for the distribution channel is essential in enhancing the performance of the organisation (Mail Online, 2010). Ginsters Company produces and distributes Cornish pastry, which is in the food industry. The food industry is among the most sensitive sectors in various economies. Management of various processes in the industry requires an appropriate approach to the ethics. There are various ethical issues in the food industry (Strbac, 2008). First, the manufacturing process of the food should embrace cleanliness and health of the consumers (Laudon and Laudon, 2002). In addition, various manufacturers of food products in the world should embrace good practices in their distribution channels in order to enhance the value of the food. Second, the marketing, manufacturing and distribution of the food product are major ethical issues. In this case, the manufacturing process adheres to various ethics such as cleanliness in the systems and use of appropriate raw materials (Fritz and Schiefer, 2009). In addition, the distribution channel should uphold the freshness of the food product in order to promot e health among the consumers. Thirdly, the environment is a sensitive ethical issue in the food

The trail of Tears Essay Example | Topics and Well Written Essays - 500 words

The trail of Tears - Essay Example Over 15,000 of our members, led by Chief John Ross, have signed a petition in protest of this false treaty. Despite this, the United States Supreme Court dismissed our concerns and this year ratified the treaty. We have now been given two years to migrate voluntarily to the west, away from our own country, to unfamiliar territory beyond the Mississippi. Forcible removal has been threatened if we do not leave on our own. Citizens of the United States, we do not wish to leave our lands, nor should we be forced to do so. Such a move would not be in our best interests; indeed it would be fatal to us as a nation. Firstly, it is an area completely unknown to us, and in addition is already occupied by other Indian nations who would not take kindly to encroachers upon their territory. We would be forced into close proximity with neighbors with whom we do not share a language or customs. The territory is also inadequately supplied with wood and water, making it much harder for us to survive. We appeal to the sense of fairness in the citizens of the United States, because previous to the false treaty, all agreements upheld our sovereign rights. Those treaties explicitly acknowledged us to be a separate people, in a separate territory comprising our own country, and were supposed to be secured and protected by your government. In the 1832 Supreme Court case Worcester v. Georgia, the majority opinion written by Chief Justice John Marshall rendered a judgment firmly upholding our rights. It stated, in part, that Indian nations should be regarded as distinct political communities, with their own territorial boundaries in which exclusive authority is exercised, as guaranteed by the United States. Although the case specifically addressed the legal question of whether the State of Georgia could forcibly seize any person residing within our nation with our permission, it forthrightly addresses our territorial and sovereign rights.

Ethics concepts Essay Example | Topics and Well Written Essays - 2000 words

Ethics concepts - Essay Example "Modern fertility treatments became the focus of much media attention in 1993 after the widely publicised case in which a 59 year old woman was enabled to give birth to twins by means of in vitro fertilisation with donated eggs and her partner's sperm. Fertility treatments raise a wide range of ethical and social issues" (Koch, 1993, p.143). Such factors as the potential child's welfare and interests are critical reasons for refusing to provide a couple with fertility treatment. In spite of the fact that the issue of conception is foremost in the present discussion, I would like to exemplify the situation with the process of child adoption. Even though it differs from conception, because the child already exists, authorities have established a number of criteria for adoption: parents' welfare, their personal qualities, health status and other information should be taken into account. These criteria are partially determined by supply and demand: for instance, potential parents are forced to compete with each other, because the number of infertile families is larger that the number of orphans who are to be adopted. Similarly, in vitro fertilization, associated with conception, poses following question: (bluntly speaking) will the child benefit from being born to these parents or would it be better if he/she never existed The likelihood of the particular potential child being born to another couple simply does not exist, and conception therefore is dissimilar to adoption in this sense. Naturally, it is hard to determine when it would be more preferable if the potential child didn't exist; the fundamental worth of an individual's life cannot be either measured or quantified, least of all if this life hasn't been started yet. It is possible to say, however, that the level of parents' responsibility would be rather low for it to be more favorable not to be born. Society's unwillingness to take care of a child excepting the most traumatic circumstances of horrible parenting proves this (Koch, 1993). Using the example of the 59-year old woman who gave birth to twins, a most important obstruction is that the mother will probably die when they are still at the stage of childhood, i.e. not having brought them up. "No doubt, other things being equal, it is preferable to have a mother who survives well into one's own adulthood. But to put this forward as a sufficient reason for denying fertility treatment is tantamount to claiming that it is better never to have existed than for one's mother to have died when one is still quite young" (Brindsen, 1992,p.280). In addition, in the case of in vitro fertilization, the interests of society are masqueraded as the potential child's interests. The procedure of selecting couples for the fertilization itself looks like the other official procedures that involve difficulties in distributing resources. There are two major hazards in failing to differentiate between the interests of the certain potential child and those of the potential children who might be born if resources were used to help other prospective parents instead. The first risk is that medical specialists may wrongly withhold the fertilization of the certain couple even if refusal to help them is not likely to bring benefit to other couples. The second hazard is that society may fail to support the process of

Management strategic-------Carry out a strategic analysis of the UK Assignment

Management strategic-------Carry out a strategic analysis of the UK grocery market using appropriate strategic management models - Assignment Example All these analyses have been carried out from the point of view of Tesco. However, references to UK general grocery market have been made times and again when required. The report concludes with the key takeaways from this detailed strategic analysis. 2. Overview of UK Grocery Market Retailing is one of the main contributors to UK economy with over 12% share. This sector acts as a bridge between production and consumption and is also a great generator of employment. In addition to the organized sector, there are a large number of unorganized players who are self-employed. UK grocery market has witnessed changes across both horizontal and vertical dimensions in the past few years. Horizontally, food retailers have ventured into other retail segments such as consumer goods, clothes, services and so on. Vertically, there has been a shift of power in the supply chain from the manufacturers to large organized retailers. This had a huge impact on the dynamics of the industry (Institute of Retail Studies 2003). 3. Internal Analysis of Tesco Tesco is primarily a food retailer with more than 2500 stores across the globe, a majority of which are in UK. The company has lately ventured into other business segments such as financial services, insurance, electrical appliances, telecommunications and insurance (Data Monitor 2004). SWOT analysis can be effectively used to carry out an internal assessment of Tesco. 3.1. Strengths One of Tesco’s biggest strengths is its continuously increasing market share. As of July, 2011, its market share is above 30% (Institute of Grocery Distribution). Tesco has almost doubled its market share in the past 7-8 years speaking high volumes of its growth. This growth has been enabled because of the continuous geographical expansion and opening of new stores. In addition, Tesco has strategically focused on non-food segment of the business and now it contributes very significantly to its revenues. Tesco has realized the importance of web i n its marketing. It has one of the biggest online supermarkets in the world. Tesco has a great brand image among its customers. It is known for high quality goods, innovative measures and efficient processes. Tesco’s lead over other players in UK market is huge. This has been made possible due to economies of scale it has gained over the years. 3.2. Weaknesses Tesco’s success story has largely been possible due to the UK market. However, it is susceptible to risk in case of change in government regulations. Tesco has a largely untapped market in emerging economies such as China and India. In addition, Tesco has been very aggressive in its expansion strategy and acquisitions. This has meant taking a large amount of debt affecting its balance sheets. Such a capital structure would work till the going gets good but may backfire in tough times. 3.3. Opportunities Tesco has opportunities from two perspectives. One is the geographical expansion in emerging markets as discuss ed above. The second opportunity is to make efficient use of its scale and venture into new business segments. The margins in the food industry are declining and it is profitable to consider new avenues. Tesco has already started working on the same with new segments such as skincare (Data Monitor 2004). In this way, it would also be able to realize economies of scope. 3.4. Threats UK grocery market has witnessed a lot of price wars. This has especially occurred due to entry of

Ethnic Marketing in Indonesia Essay Example for Free

Ethnic Marketing in Indonesia Essay Indonesia’s national slogan  « Bhinneka ika tungat.  » that means unity and diversity, is a strong local motto that celebrates differences, specially the demographic one. This slogan was adopted at independence in 1945. This can indicate in a first approach a strongly united population, a country where people are allowed to practice and conserve their ethnic Identity. But this never was the general case in Indonesia. There is this insidious ordinary racism in the country that takes place in their everyday living. Because this sacred diversity is however limited to ethnic groups with claims to a territory: this includes the Javanese, the Sundanese and the Madurese. There are other local groups that are not as significant. For the other groups that can not have the same claims, it is another story especially when it comes to the Chinese Indonesian. Being migrants with powerful and strategic positions, they are often excluded by the population or they exclude themselves. If this is how the Indonesian society can be perceived, it isn’t the same when it comes to the marketing approach. It can be said that it is not that simple to talk about ethnic marketing in Indonesia when it is related to physical characteristics. If the comparison was made with Singapore, It is much easier to identify that a person belongs to a certain ethnic group when she is shown in an advertisement. It becomes more delicate when the ethnic groups have a lot of similarities. Even if Chinese, Indo or Arab origins Indonesians are not accepted everywhere or not recognized as true Indonesian by a part of the society, they still have their place and are represented for marketing purposes. We can give an example of Western Union: For the first Ad, adressed to the chinese Indonesian poulation, the person is an office working man, we would rather think that he has a good salary and is educated. The emphasis here is about the importance of the speed of the transaction. For the second Ad, more adressed to Indonesians with claims of territory, The main character is a little girl that due to the received money, could go to school. It shows the importance that is taking girls education in those groups. When it comes to the language, companies that operate at a national level generally use Indonesian or English for their advertisement campaigns. The use of a specific language related to a group is more likely to stay in the frame of small companies that operates in very restricted areas.

Sample Reflection Assignments Essay Example for Free

Sample Reflection Assignments Essay Written assignments are of two types: Reflections and Project Reports. Reflections: An essential element for student learning in service-learning courses is written and oral reflections on the field study experience, as well as on other elements of the course. To have an experience isn’t enough to ensure learning; you need to intentionally and thoughtfully reflect upon the experience and what you learned from it to ensure that learning occurs. As T.S. Eliot once wrote (The Four Quartets, New York: Harcourt Brace, 1943, p. 24), you can â€Å"have the experience but miss the meaning.† Towards this end there are eight written reflections required in this course. These reflections are intended to help you focus in on what you are learning (or not learning), identify issues or concerns on your mind, explore an idea more deeply, or in other ways enhance your learning about the course topics, yourself, and others. According to the North Carolina State Service-Learning Program (Reflection and Articulating Learning, Faculty Center for Teaching and Learning. NC State, 2004) â€Å"the best reflection follows a simple three step model: (1) describe the experience(s) objectively, (2) analyze the experience(s) in terms of the categories of service-learning objectives (personal, civic, academic), and (3) articulate (express) the learning that results. We will go over these steps as part of our first reflection exercise. These reflections should be approximately two pages long (500 words). They will be graded. The best six out of eight grades will be used towards your final grade. Evaluation of reflections will use a set of criteria (rubric) to be distributed and discussed in class. Project reports: There will be a series of written assignments related to your service-learning project. In preparation for the write-up of the final project report for the community partner (along with other possible final products like videos, curricula, maps, etc.), students will prepare a written work plan and two progress reports (schedule to be provided). All of these written assignments will be graded and become part of the final grade. Details on all of these written assignments will be provided and discussed in class. COURSE: Cultural Health Care (NURS 105) INSTRUCTOR: Rycki Maltby PhD, RN, FRCNA Final Paper (25%) The purpose of this paper is to synthesize your learning over the semester. The paper should be 8-10 typed (word processed) pages, 12 cpi, and follow the attached guidelines for written assignments.

Development Sem.: Communities and Human Development (PSY 366) FACULTY: Lynne Bond Final Writing Assignment: At the end of the semester, you will be assigned a final writing assignment. The purpose of that assignment will be to help you integrate the reading, writing, discussion, and data gathering, analysis and interpretation we have done during the semester. The exact format of that assignment will be shaped, in part, by the development of our community-based project. As we progress throughout the semester, we will work together to develop more explicit guidelines for this project. COURSE: Community Psychology (PSY 295) FACULTY: Lynne Bond Analytical/Critical Reflection (2 pages): These brief papers are to focus specifically upon the week’s reading assignment and its relation to our community field work, other readings, and personal experience and observations of your own. Your goal is not to summarize the readings. Rather, you should analyze and reflect critically upon a couple significant issues raised in the readings. To reiterate, ideally you will critically reflect upon these readings by linking them with other material we have covered in our course (readings/discussion), community field work you have done, and other aspects of your experience and knowledge (e.g. personal history, issues observed in media, other courses†¦etc.). We will discuss and practice â€Å"reflection† activities in class at the beginning of the semester to help you feel more comfortable and prepared to complete these reflection papers. Intro to the Nonprofit Field (Carrie Williams Howe) Final Reflection Assignment: WHAT? What have you learned through this course? What stands out to you, feels new to you, excites you, or challenges you? SO WHAT? Why does this learning matter? Why does it stand out to you?

Human Computer Interaction Assignment English Language Essay

Human Computer Interaction Assignment English Language Essay Technology has had a big impact on society, as it has made many drastic improvements to the way life in general has changed and improved so much. For instance, technology has improved usability of software and hardware in society. In addition specialised interfaces have helped people with disabilities enabling diversity to take place. Describe the impact of HCI on society, the economy and culture, providing 5 (five) examples of each topic. Society Touch screen phones, using phones is now easier because of the touch screens Input/output Game controllers, game controls allow you to play a game and connect with others by sending messages or attaching a microphone to it to talk Remote control, allows you to remotely control something without being right next to the thing you want to control Head up Display, would be good for drivers since they wont have to look away from the road to see how fast theyre going Economy Text readers, also known as text to speech Voice input, example telling a lamp to switch off and it switches off Thought input, wheel chair users will have the ability to control their wheel chair by just thinking about it Mobile communication, ability to call or text anyone world wide Reduced complexity of input, everything is simple and requires no more than 2-3 options of input Culture Games, allow people to connect with each other allowing one another to have an open mind and talk to different people with different opinions and thoughts Deskilling work, androids/robots will replace the easy things humans do, e.g. at tesco and a few other places you can serve yourself and self-checkout Mobile entertainment, youre now able to watch videos about different cultures with your mobile Laptops, ability to search the internet, interact with others, watch videos Domestic appliances, things like microwaves diswashers Task 2 (P2) Considering that the HCI design principles create a big impact on a users experience of a hardware and software product, explain the Schneiderman (eight rules) and Nielsens ten usability heuristics principles. Remember to explain perception, behaviour models and information processing. Schneiderman Strive for consistency: either it be the consistent same lay out or colours, or the identical terminology used in menus, prompts and help screens, if it is in a similar situation it should all be the same or somewhat similar. Enable frequent users to use shortcuts: A regular user of a device or a certain type of application should have the ability to have a shortcut to things they use the most; this would speed up the work flow. Offer informative feedback: When a user is interacting with their device or application, they should receive feedback that gives them a clear representation and is also understandable. Design dialog to yield closure: A users gets a good feeling when they know there is a flow to what ever theyre doing, that everything is in a chain, one thing has to happen in order for another. For example, sending a message on an application such as whatsapp first you need to add the contact, then the message its self, and then after youve sent the message it shows a D letting you know its been delivered. Offer simple error handling: If something goes wrong with a device, a simple type of hint should pop up to help the user with the problem that occurred. If a certain app crashes it should ask the user if theyd like a error report to be sent. Permit easy reversal of actions: In other words undo this is needed in a HCI because it would prevent any permanent mistakes. Support internal locus of control: a user should receive some what a type of display letting the user know that something is actually happening. Lets say a user attempts to open a app and the app is taking a few seconds to get ready and open up, the user would instinctually think the app didnt respond to his/her touch so he/she will attempt to reopen the app multiple times until the app malfunctions. Reduce short-term memory load: When a user is using a device they shouldnt be thinking about the amount of times theyll need to push a button or what not, it should be a simple click of a button, and with menus it shouldnt require a button push to go up or down it should be a simple scroll bar. Nielsens ten usability heuristics principles Visibility of System Status: The system should have a certain type of way to let the user know what is happening and with a good time. Match between system and the real world: The system should be able to speak the users language, with the correct words and the right concepts and with the right time, so it is communicating clearly with the user User control and freedom: Sometimes when youre using a device in a rush you tend to open random applications and then you have the ability to instantly abort the application, without having to go through the process of the extended dialogue. Consistency and standards: The system should always have continuity across the platform. Error prevention: The better the design is the one with the better error recovery, but also prevents users from making the same errors twice. Recognition rather than recall: The user shouldnt have to remember the information from dialogue to another, it should all be recognisable and visible to the user. Flexibility and efficiency of use: The system should have accelerators, which are unseen to the regular user but they allow the expert user to do things and navigate faster with more frequent actions. Aesthetic and minimalist design: Dialogues shouldnt contain information that is not needed in that specific area, you should always make sure your system is efficiently composed. Help users recognise, diagnose and recover from errors: Error messages and error prompt boxes should explain the problem in plain language without code, and should also precisely indicate whatever the problem may be and also give advice to the user on a solution. Help and documentation: Although a system is better without documentation, it might be necessary to provide the help and documentation, so that any such information should be easily searched for and found. It should also be focused on what the users task is and list the steps to be carried out. Task 3 (P3) McCann Phones a small and up and coming new mobile phone producer has decided to develop a new mobile phone interface for its next series of mobile phones to replace its highly successful first range. The developers have come up with three possible interfaces and they need to decide which one to use. It has been decided to carry out an investigation on the alternatives prior to production. You have the support of the software engineers and production manager so prototypes will be made available to you. As you are the resident usability evaluator it is your task to carry out any necessary survey work and to come up with proposal. Here are the three possible interfaces: The convention qwerty keyboard as used in most computer systems. An alphabetical keyboard (a, b, c, d, e,,z) A keyboard based on frequency of character us (e, t, a, o, n, rz) Design the input and output of your mobile prototype. Choose one of the suggested interfaces and explain why. F:Unit 23 HCITemplate of phone design.jpg Clicking either one of these buttons will open up a certain app/webpage, depending on the one you click, for instance if you click on the one with f will open up a Facebook app or webpage. Reason why Ive added this to my mobile prototype is because people now use these two to communicate with each other, with the button input being there, itll allow you to get in contact faster and easier considering all youd have to do is click a button. Task 4 (P4) The knob in the centre of this washing machine system controls the different fabric washing systems and the settings for rinse and spin. The control does not have a stop in either direction; in other words it continues to go all the way round to the next cycle. Create input and output for this machine which would be best for adjusting the cycle according to the fabric, temperature, speed and timer. You could draw a picture to help you explain the reasons. Provide two new ideas that are not available in the industry. img_0193.jpg Below is what my design would look like and I will be explaining the two things that Ive implemented into my design that havent been used in the industry. 2. Touch screen, everything you input will be touch done via the new sleek touch screen design. Child lock passcode, this will be programmed in a way that it will be child proof, for example if you want to lock your machine after it has started and keep every button locked, youll enter the child lock. It is designed in a way so that no matter what you push nothing will be happening but to deactivate the lock youll first have to enter the first 2 digits right, this will then enable you to see what youre inputting and then you enter the rest of your passlock to unlock the machine. G:Unit 23 HCITask 4 Design 1.png Task 5 (P5) Based on the case scenario before, explain how you would test your system according to its functionality. Comment on the usefulness of such system and point out any drawbacks. Testing the system child lock To test the system youll first have to enter a child lock pass lock and then attempt to push any of the touch screen buttons and see if anything happens, and nothing should happen if the system is correctly made. This will be useful considering little children love to stand beside the washing machine when its spinning and tend to push buttons, but with the child lock they wont be able to push any buttons. The downside to this system is that the password is 4 digits long and to have half access to the system youll have to correctly enter the first 2 digits otherwise youd just be pushing the keys and nothing would be happening, so the drawback would be if you forgot the passcode you would have to end up calling the company to come and reset your password. Testing the touch screen To test this youll have to push what you want, for example, cotton, with 50 degrees Celsius and then on high spin, if the system is working properly it would input the material first and then the temperature and then lastly the amount of spins it will be doing. The touch screen with the options is useful because its simple to use and you can adjust it to the way you want it and wont have to clock the washing machine knob to the way you want it, you just have to input the things you want with a touch of a button. The big drawback to having a touch screen is that if it is dented or broken it will be not be operating properly, it probably wont even be operating at all, so you wont be able to input anything. Task 6 (P6) Bionic vision was once the preserve of futuristic technology shows. However, those Tomorrows World days could soon be reality with a pair of glasses linked to a computer offering hope to thousands of visually impaired people in Britain. Current technology that can give profoundly visually impaired people a form of sight through a retinal implant is expensive and invasive, so developing an affordable, non-invasive alternative would be a welcome improvement. And this is exactly what scientists at the University of Oxford are working on. The technology works by having a tiny video camera mounted on to a pair of glasses, which relays information to a small computer in the users pocket. The computer recognises objects or people and relays the information to the lenses via tiny LED lights. (Light-emitting diode). People would see a bright light within the lenses themselves to indicate an object. The brightness of the light would then indicate how close, or how far away the object was and that may be enough for the wearer to navigate their way around. Using a computer to interpret the world on behalf of the wearer means we could use different coloured lights in the lenses to allow different types of information to be fed back to the wearer explains Dr. Stephen Hicks, research associate in the Department of Clinical Neurosciences at the University of Oxford. The advances in mobile phone and computer game technology, such as face recognition, tracking software and depth sensors enable the visually impaired to access a whole new host of possibilities. (Extract from Metro, September 19, 2001) Explain how you would design the device and document how you would consider the input, output, the quantitative measures and qualitative measures of effectiveness of your product. This would be designed on a pair of glasses with a lens that is 5cm thick, it would need to be sort of thick to fit in a pair of small LCD screen into each of the lens. The input and out put would work in a way with different bright colours, for example if the area is clear of objects and people it would be a black light with a blue light highlighting the walls so that the user of the glasses doesnt bump into the walls, and if the user is near people it would be a black light with green light highlighting approximately where the object or person is so that the user doesnt bump into them. If its dark at night instead of the backgrounds being black they would be white and objects, people and walls would be highlighted with purple. The glasses would also be implemented with a vibrator and a sound card to make beeping noises when someone gets close to an object within a close radius of 50 centre meters, and depending on how low/high the object is, it will make a beep vibrate, the user has the ability to switch one of these of. Each beep and vibrate will have a different meaning for example if a object is really close to the person and they can walk over it, it would simple beep twice and vibrate twice, just in case they didnt hear the beep. C:Usershijh0736Pictures48416_1 copy.jpg Ear piece attached to the glasses that goes into the users ear, it sends beeping signals depending on the diameter of how close they are to a object, they can get the settings changed from where they where given the product, just in case the beeping gets annoying or they want to change the frequency of the beeping. LCD screen projecting lights, black background, with green to represent a object. If the person that is vision impaired isnt impaired badly, then they can ask someone to change the settings of the screen so that the black background is taken away and it is just see through but it would still highlight objects as green. If the person that is vision impaired is badly impaired, no need to worry their is a ear piece that also helps, with beeping when coming in close contact to a object.

Single Chain Antibody Production

Single Chain Antibody Production ABSTRACT The study aimed to characterise His- and Myc- tagged scFv MFE-23 antibodies produced from transformed E.coli cultures using ELISA and immunohistochemistry assays. Anti-His, anti-myc and anti-MFE secondary antibodies were used in the CEA/PBS coated ELISA plate with horseradish peroxidase-OPD chromatic reaction for detection. Culture 1 was identified to produce MFE-His and culture 2 giving MFE-Myc antibodies. The immunohistochemistry assay confirmed the CEA binding profile of scFv MFE-Myc by the comparison between negative controls, positive anti-CEA binding reactions and 4-stage anti-Myc binding of the scFv MFE-Myc examined. The CEA specificity displayed by tagged scFv MFE-Myc can be utilised in antibody-based cancer therapy by targeting tumour antigens specifically. INTRODUCTION Cancer arises due to the defective regulation of normal cell proliferation and homeostasis. This allows tumours to possess the capabilities including self-sufficiency in growth signal, insensitivity to antigrowth signals, avoidance of apoptosis, unlimited replicative potential, sustained angiogenesis and metastasis.1 In additional to the surgical removal of tumours, conventional cancer therapies such as radiation, chemotherapy and immunotherapy have a focus in inducing cytotoxicity against malignant cells. With better understanding of the molecular biology of carcinogenesis, targeted therapies are being developed to achieve lower toxicity to normal tissues and higher clinical efficacy through disrupting pathways that contribute to the tumours proliferative advantage. Attempts are also being made in developing cancer gene therapies to compensate or repair the mutated genes. All tumours express their unique set of antigens on cell surface which can be a result of genetic alterations, upregulated self-antigens or tissue-specific antigens that can be utilized to distinguish cancer cells from normal cells. Antibodies, one of the effectors in immune response, are Y-shaped proteins that each recognizes and binds to specific antigen (Figure 1). The protein consists of two light chains and two heavy chains, with variable (Fab) and constant (Fc) domains on each of the chain. The region of the antibody at which antigen binds is referred as the Complementary Determining Regions (CDR) present at the variable Fab region. The Fc region is responsible in modulating immune response through activation of the complement cascade and Fc receptor mediated activation of effectors such as phagocytes, mast cells, neutrophils and Natural Killer (NK) cells.3 The initial approach of antibody-based cancer therapy is to tag cancerous cells as foreign and eliminate such targets thro ugh cytotoxic effectors of the human immune system. Antibodies against essential growth factors can be synthesized to sequester such molecules from further promoting tumour growth. The high specificity of antibodies to particular antigens also serves as a vehicle in delivering killing machineries to tumour cells. For example, antibodies can be directly conjugated to radionuclides, toxins or cytokines, or indirectly to the surface of liposomes carrying drugs or toxins.4 Antibody-directed enzyme prodrug therapy (ADEPT) is also available in which the antibody targets an enzyme selectively to the tumor where it converts a relatively non-toxic prodrug to a potent cytotoxic drug.4 These various strategies aim to minimize the systemic toxicity afflicted by the cytotoxic agents administered. Monoclonal antibodies are usually preferred compared to polyclonal ones, as they recognize specific epitope of an antigen and hence have greater specificity. Carcinoembryonic antigen (CEA) is first identified as a glycoprotein in the human colon cancer tissue extract and fetal gut, and plays a role in cell adhesion.5 Although CEA can also be detected in normal gastrointestinal tissue, the glycoprotein is overexpressed on the plasma membrane of colon cancer tissues.5 CEA level has also been found to be highly elevated in various cancers of an epithelial origin such as breast, lungs and pancreas.5,6 Moreover, normal CEA is localised on the luminal surface of columnar epithelial cells lining the crypts of the intestine so the glycoproteins are not directly accessible to the blood flow.6 However CEA is usually found on all sides of the cell membranes in tumours. Thus, CEA can be a useful target on cancer cells in immunotherapy using anti-CEA antibodies. The objectives of this lab practical are to introduce the applications of antibodies in cancer therapy and diagnosis through immunohistochemical staining of tissues. It also serves to familiarise students with the enzyme linked immunosorbent assay (ELISA). This is achieved by the production of MFE-23 single chain Fc antibody fragment (scFv) against CEA from transformed E.coli cultures. The scFv MFE-23 can be linked to either a His- or a Myc- tag. The unknown antibodies are characterised in the ELISA assay using appropriate detection antibodies, and the chromatic reaction between horseradish peroxidise (HRP) and OPD substrate. The scFv MFE-23 obtained by students is also used in the immunohistochemical characterisation in cryostat sections of normal and cancerous human tissues. MATERIALS METHODS E. Coli growth curves E.coli cultures were transformed with pUC119 containing either His- or Myc- tagged scFv MFE-23 (Culture 1 2) and were incubated overnight. The expression of pUC119 was controlled by the lac operon, which could be induced by either lactose or lactose analogue isopropyl-1-szlig;-D-thiogalactoside (IPTG). The vector also encoded for ampicillin resistance. The E.coli cultures were grown with ampicillin selection and 0.05% glucose. Optical density (OD) readings at 600nm were taken at 30min interval until OD=0.9 when IPTG was added to both cultures to induce pUC119 expression and hence scFv MFE-23 production. A negative control of 2xYT was set up, and all three cultures were incubated at 30? overnight. Full experimental procedures are described in Appendix 1. ELISA assay The ELISA assay aims to characterize the identities of the tags conjugated to scFv MFE-23 obtained in the supernatant of the overnight E.coli cultures. Detailed protocols of the assay can be found in Appendix 1. 36 wells of the 96-well ELISA plate were coated with the CEA antigen or phosphate-buffered saline (PBS) as its negative control. Supernatant of the overnight E.coli cultures 12 from the bacterial growth curve assay was obtained which contain either His- or Myc- tagged scFv MFE-23. The supernatant samples 12, the positive control MFE-his-myc antibodies and the negative control 2xYT growth medium were added to the corresponding wells as indicated in the format diagram in Appendix 2. Secondary antibodies rabbit anti-MFE23 polysera, mouse monoclonal anti-HIS tag (TetraHis, Qiagen) and mouse monoclonal anti-MYC (Sigma) were added to the corresponding wells (Appendix 2) to bind the primary antibodies present. Tertiary horseradish peroxidase (HRP) conjugated antibodies against the secondary antibodies goat anti-rabbit HRP (sigma) and sheep anti-mouse HRP (Sigma) in blocking solution were added to the wells (Appendix 2). OPD substrate buffer was applied to each well to detect the presence of HRP, which should give a yellow-orange product in case of positive result. HCl was added to stop the reaction when colour has developed, and the OD at 490nm for each well was measured. Immunohistochemistry assay Five glass slides, each containing 2 colonic adenocarcinoma, 1 normal colon and 1 normal liver tissue sections were fixed and processed for immunohistochemical staining. Avidin-biotin-peroxidase complex (ABC complex) was added following the application of biotin-labelled antibodies. The localisation of antigens was visualised by the formation of brown pigments, as peroxidise reacts with the diaminobenzidene (DAB) substrate. Lattices of several peroxidase molecules were formed to amplify the binding signal from the biotinylated antibody.7 A summary of the treatment given to each slide was illustrated in Table 1, and the complete protocol can be found in Appendix 1. RESULTS E. Coli growth curves Both E.coli cultures transformed with either His-tagged scFv MFE-23 or the Myc-tagged version in a pUC119 vector follow a similar exponential growth curve, as shown by the plot of OD600 against time (Figure 2). The bacterial cultures were in lag phase at t=0-90, and the log phase from t=90. It took approximately 175minutes for the cultures to reach OD600=0.9. The PBS negative controls in wells A-F/7-12 worked relatively accurately with low OD490 readings. Most readings also corresponded to the negative controls in the CEA coated wells (B4-6, D4-6, F4-6) but with 2xYT added instead of primary antibodies. However, the OD490 readings for wells C10-12 and E10-12 were higher than most readings from the negative controls. The higher OD490 readings obtained in certain wells in comparison of their corresponding negative controls indicated the presence of yellow-orange product formation from reaction between HRP and OPD substrate. These positive outcomes found in certain wells are highlighted in the shaded cells of Table Immunohistochemistry Assay Figure 4 shows the immunohistochemical binding reactions for the negative controls (slides 3-5). Slide 3 acts as a negative control for slide 1, treated with the 4-stage anti-Myc technique but omitting the primary Myc-tagged scFv MFE-23 antibody. Thus we should not be able to visualize the localization of CEA antigens due to the absence of MFE-23 binding on slide 3. Slide 4 is a negative control for slide 2, omitting the mouse monoclonal anti-CEA A5B7 antibody treatment in the 3-stage mouse monoclonal technique. No binding reaction is expected on slide 4 as well. Slide 5 was treated like slide 4 but without initial biotin/avidin blocking. As expected, the colonic adenocarcinoma tissue section of slide 3 does not display brown colouration and hence there is no binding reaction to the cytoplasm of tumour cells and connective tissues. Binding reaction to the cytoplasm of cryptal epithelium is not seen for the normal colonic mucosa, although there are strong brown colourations for a few cells in the lamina propria. The normal liver tissue on slide 3 shows some weak reaction with the parenchymal cells. Similarly, the parenchymal cells of the normal liver tissue on slide 4 do not display brown colouration and hence indicates the absence of binding reaction. On slide 5, the normal parenchymal cells are positive for binding reaction, demonstrating the presence of biotin in normal liver. Figure 5 shows the immunohistochemical binding results of slides 1 and 2. Slide 1 was treated with the 4-stage anti-Myc technique and slide 2 is the positive control treated with the 3-stage mouse monoclonal technique (See Table 1). For the colonic adenocarcinoma tissue on slide 1, strong brown colouration is present in the cytoplasm of tumour cells and the basement membrane of malignant acinar structures. Weak positive binding reactions can also be observed in fibrovascular stroma. The normal colonic mucosa of slide 1 shows strong reactions to the cytoplasm of goblet cells in the cryptal epithelium as well as a few cells in the lamina propria. The normal liver tissue shows only weak positive reactions with the parenchymal cells. Thus the scFv MFE-myc antibody was reactive with both normal colonic epithelium and adenocarcinoma, but not the biotin/avidin blocked liver tissue. The colonic adenocarcinoma tissue on slide 2 shows strong reactions with the tumour cell cytoplasm and the basement membrane of malignant acinar structures similar to the reactions seen in slide 1. Weak positive results are obtained in fibrovascular stroma of the positive control slide. As the binding reaction of slide 1 was similar to that of the positive control, this confirms the CEA reactive profile of the scFv MFE-myc antibody from the E.coli supernatant sample 2. DISCUSSION E.coli Growth Curve Both E.coli cultures followed the exponential growth curve as expected. However, the growth curve was obtained in the absence of a negative control i.e. same volume of 2xYT to be treated in the same way as the two cultures. The lack of a proper negative control means that the possibility of contamination cannot be eliminated. Thus it is unknown whether the increase in OD600 readings was partially attributed to culture contamination. ELISA Assay As mentioned in the results, the OD490 readings for wells C10-12 and E10-12 were higher than most readings from the negative controls. This might indicate contamination of these wells with CEA antigens, or insufficient PBS washing following the application of HRP-conjugated antibodies. Wells A-B/1-6 were applied with anti-His secondary antibodies and so would indicate the presence of His-tag by the production of yellow-orange product. Wells A1-3 were treated with supernatant from bacterial culture 1 and wells A4-6 with that of culture 2. As higher readings of OD490 in the positive control B1-3 and wells A1-3 were obtained compared to the negative control B4-6, the culture 1 supernatant contained the His-tagged scFv MFE-23. Wells C-D/1-6 were applied with anti-Myc secondary antibodies and so would indicate the presence of Myc-tag by the production of yellow-orange product. Wells C1-3 were treated with supernatant from bacterial culture 1 and wells C4-6 with that of culture 2. As higher readings of OD490 in the positive control D1-3 and wells C4-6 were obtained compared to the negative control D4-6, the culture 2 supernatant contained the Myc-tagged scFv MFE-23. The anti-MFE antibodies added to wells E-F/1-12 can bind to both His- or Myc-tagged scFv MFE-23. Thus binding should occur against primary antibodies from both cultures 12 and also the positive MFE-myc-his control, as demonstrated by the higher OD490 readings in wells E1-6 and F1-3 compared to the negative controls F4-6. It can be observed that the anti-His antibody gave a stronger signal than anti-Myc and was due to anti-His binding more strongly to its target than anti-Myc (Unpublished results, Kogelberg, H.). Comparing the OD490 of wells E1-3 and E4-6, absorbance of anti-Myc was slightly higher than anti-His despite the lower binding affinity of anti-Myc. Thus there might be a higher concentration of MFE-Myc in the culture 2 supernatant than MFE-His in culture 1, although technical issues like washing times, salt concentration and pH, or structural characteristics affecting the accessibility of antibody can affect the amount of binding. Immunohistochemistry Assay The results obtained from slides 1 and 2 confirm the CEA reactive profile of scFv MFE-myc antibody, as both slides displayed similar binding reaction patterns in colonic adenocarcinoma. The weak positive signal in normal liver tissue in slide 1 is likely to be caused by cross-reaction of secondary mouse anti-Myc antibodies, as similar result can be observed in the negative control (slide 3). Primary antibodies may also cross react and bind to non-target tissues. This demonstrates the possible cross-reactions with antibodies and hence the importance of negative controls to eliminate such artifactual reactivity. The strong binding to goblet cells cytoplasm in cryptal epithelium of normal colonic mucosa in slide 1 is consistent with the findings of CEA present in normal colonic mucosa.5 Although CEA level is lower on normal colonic mucosa, their presence implies that antibodies against CEA in cancer therapy may target normal cells other than malignant cells. Thus it is important to control anti-CEA antibody concentration used to avoid imposing toxicity to normal tissues yet is effective in producing a clinical response on cancer. The negative controls (slides 3-5) allowed the assessment of the level of binding for secondary, tertiary and quaternary antibodies/reagents. The slides also revealed any endogenous background material that might be confused with specific binding of primary antibodies, as well as information about the basic pathology of tissues. The inclusion of normal liver sections helped illustrate the importance in carefully controlling the specific reactions of test antibodies with potential targeting specificity for other cellular proteins. The ABC complex for detecting biotinylated horse anti-mouse antibodies can also react with biotin present in liver and give a positive non-specific result. This unwanted reaction as seen in slide 5 can be prevented by biotin blocking treatment of tissue samples. Moreover, myeloperoxidase white cells containing endogenous peroxidase can react with the DAB substrate and produce brown colouration even in the absence of ABC complexes. The normal colonic mucosa in slide 3 provided examples of such artifact. The naturally occurring bile pigments in liver seen as green/brown granules under high-power bright field microscopy can also be found occasionally. Careful interpretation of slides is required to avoid false judgments as there can be false positive reactions. In addition, it should be noted that adequate fixation of the sample is important in successful localisation of antigens present and hence an accurate representation of antigen distribution profile. The procedure helps to ensure the preservation of tissue morphology, the immobilisation of antigen and the preservation of antigen immunoreactivity. It is also important to ensure optimal fixation for an adequate permeability of the tissue to the immunochemical reagents. Other than mmunohistochemistry, western blotting and immunoprecipitation (IP) can be carried out to confirm scFv specificity. Antigens transferred to nitrocellulose membrane can be probed by specific antibodies in western blot, or precipitated out of lysate using antibodies in IP. Affinity chromatography can also be used which is a method of separating biochemical mixtures based on highly specific biological interaction. Specific antigen can be covalently coupled to a solid support and allow supernatant with the testing antibody to flow through so that only specific antibodies will be bound to the antigens. The assay used in this study can only detect antigens in a non-quantitative way with chromatic display of antigen localisation. Instead radioimmunoluminography (RILG) can be used for quantitative measurements of antigen concentration along with its distribution in histological sections.8 Radiolabelled antibodies against specific antigen can be applied to tissue sections and bound antibodies are mapped by phosphor imaging. Radioactivity detected in each pixel of the digital image will be proportional to antigen concentration if saturating antibody concentration is used. Future Perspective of Antibody Targeted Cancer Therapy The successful application of scFv MFE-23 with a Myc-tag at its C-terminus for detection in immunohistochemistry proves that the attachment of small molecules to the antibody will not affect its specificity for CEA. Thus the scFv chain can be conjugated to cytotoxic reagents or to be used for ADEPT as mentioned previously. The potential clinical efficacy of scFv MFE-23:enzyme fusion protein has been shown in nude mice with human colon adenocarcinoma xenografts by the Bhatia group.9 Moreover, scFv MFE-23 can be used in radioimmunoguided surgery (RIGS) based on the pre-operative injection of a radiolabelled anti-tumor antibody to detect tumour deposits during surgery. A Phase I clinical trial of RIGS using 125iodine-labelled MFE- 23-his scFv has reported good selective localisation at sites of primary colorectal cancer and metastases.10 As illustrated by MFE-23 scFv fragment, antibody targeting has the potential for selective imaging or delivery of anti-cancer molecules. Antibodies can be engineered to modify their biological properties with increased specificity and functionality. This is achieved by reducing antibody size, altering valency, and fusing to different molecules to improve therapeutic efficiency. Scientists have been trying to produce smaller antibody fragments but retaining specific binding to antigens, in order to minimize immunogenicity and achieve better tumour penetration. Continuous research on the specificity and stability of these fragments, and hunting for more tumour-specific antigens are required to further expand the field of antibody-targeted cancer therapies. Slide 3 is a negative control for slide 1 which was treated with the 4 stage anti-Myc technique. Slide 4 is a negative control for slide 2 which was treated with the 3 stage mouse monoclonal technique. Slide 5 is a negative control for slide 2 as well but without biotin/avidin blocking. Slide 1 was treated with the 4 stage anti-Myc technique, and slide 2 was treated with the 3 stage mouse monoclonal technique. REFERENCES Hanahan D, Weinberg RA. The hallmarks of cancer.

APPENDIX Appendix 1 Experimental Procedures (UCL Cancer MSc Lab Practical 2 Handout, 12-13Nov09) E. Coli growth curves E.coli culture transformed with pUC119 containing either His- or Myc- tagged scFv MFE-23 (Culture 1 2) were incubated overnight. The expression of pUC119 was controlled by the lac operon, which could be induced by either lactose or lactose analogue isopropyl-1-ß-D-thiogalactoside (IPTG). The vector also encoded for ampicillin resistance. 30 µl of the media was added to 15ml growth media with ampicillin selection and 0.05% glucose. Both tubes on loose caps were placed into a 37? shaker at 225rpm and time was taken as t=0. Optical density (OD) of the culture was measured with a spectrophotometer at 600nm from t=0 at a 30min interval until reading reached OD=0.9. 1mM IPTG was added to each culture and the tubes were incubated at 30? overnight with shaking. A negative control was set up using the same volume of growth media 2xYT with 1mM IPTG for overnight incubation. ELISA assay 100 µl of 10 µg/ml CEA antigen was applied to strips 1-6, A-H of the 96-well ELISA plate. 100 µl of PBS was applied to strips 7-12, A-H as negative controls. The plate was covered with plastic film and incubated for 1 hour at room temperature. Each well was rinsed 4 times with PBS and blocked with 200 µl 5% Marvel milk/PBS. The plate was covered and incubated overnight at 4?. The plate was washed with PBS 4 times after the overnight incubation. Overnight bacterial cultures and the negative control were centrifuged at 4000rpm for 20minutes to obtain the supernatant. 100 µl of each supernatant sample and negative control was added to the ELISA plate according to the format diagram as seen in Appendix 2. The covered plate was left at room temperature for an hour. The plate was then rinsed twice with 0.1% Tween-20/PBS and 4 times with PBS. 100 µl of secondary antibodies rabbit anti-MFE23 polysera, mouse monoclonal anti-HIS tag (TetraHis, Qiagen) and mouse monoclonal anti-MYC (Sigma) with a concentration of 1:1000 in 1% blocking solution was added to the wells according to the format diagram: anti-His A1-12 and B1-12; anti-Myc C1-12 and D1-12; anti-MFE E1-12 and F1-12. The covered plate was left at room temperature for an hour. The plate was washed again twice with 0.1% Tween-20/PBS and 4 times with PBS. 100 µl horseradish peroxidase (HRP) conjugated antibodies against the secondary antibodies 1:1000 goat anti-rabbit HRP (sigma) and 1:500 sheep anti-mouse HRP (Sigma) in 1% blocking solution was added to the corresponding wells. The covered plate was left at room temperature for an hour, and then rinsed twice with 0.1% Tween-20/PBS and 4 times with PBS. 100 µl of OPD substrate buffer was added to each well to detect the presence of HRP, giving a yellow-orange product in the case of positive outcome. 100 µl of 4M HCl was added when the colour has developed, and OD was measured at 490nm with an automated plate reader. Immunohistochemistry assay Five glass slides, each containing 2 colonic adenocarcinoma, 1 normal colon and 1 normal liver tissue sections were removed from the freezer and air dried for 5minutes. Slides were fixed in acetone in 10minutes and rinsed in tap water for 2minutes. Slides were flooded with PBS and Avidin blocking solution was applied to slides 1-4 for 10 minutes. Slides 1-4 were rinsed in PBS and applied with Biotin blocking solution for 10minutes followed by PBS wash. PBS was removed from slide 1 and flooded with 1:20 normal horse serum in PBS for 15minutes. Slide 1 was drained and applied with bacterial supernatant containing Myc-tagged scFv MFE-23 antibodies for 45minutes. Slide 1 was then rinsed with PBS thrice over 10minutes, and 1:20 normal horse serum in PBS was added to slides 2-5 for 15minutes. 20 µg/ml of mouse monoclonal anti-Myc antibody (Qiagen) in PBS was added to slides 13 and left for 35minutes. 20 µg/ml of A5B7 anti-CEA antibody was added to slide 2 for 35minutes. Slides 4-5 were washed in PBS. Slides 1-3 were rinsed with PBS thrice over 10minutes. 1:200 biotinylated horse anti-mouse immunoglobulins in PBS with 5% normal human serum was added to all slides and incubated for 35minutes. All slides were rinsed with PBS thrice over 10minutes. The avidin biotin-peroxidase complexes reagent (ABC reagent) was added to all slides, followed by PBS wash 3 times over 10minutes. 0.03% of hydrogen peroxide in 1mg/ml 3,3,diaminobenzidene tetrahydrochloride solution was applied to all slides immediately and left for 5minutes. Slides were washed with tap water. All slides were stained in Harris haematoxylin for 40seconds, rinsed in tap water and left for 5minutes for colour to develop. Slides were then dehydrated through graded alcohols (70/95/100%), cleared in inhibisol and coverslip using DPX mountant. The slides were then ready for observations under the light microscope.
