Out of Shadows Themes

Change and racism evidently aids the characterization and the development of the text because these significant themes help the portrayal of the characters as they are relatable In society. The text being explored Is â€Å"out of the Shadows† by Jason Wallace. Change reoccurs throughout the text which helps to develop Roberts character. Similarly, the major connotation of racism also engages readers to relate to the changes of Roberts and Van's character. Change is evident in the development of Roberts character as he experiences his journey with Ivan and his friends.At the beginning of the text, Out of the Shadows by Jason Wallace, Robert has an awkward confrontation with his ex-friend Nelson when he was with Ivan. Knowing how Ivan would react, Robert harshly told Nelson to leave him alone and not to mind his business. This is demonstrated in the quote, â€Å"l don't know why I felt surprised, wasn't that what I'd been after? † The use of the soliloquy creates an impre ssion that Robert is realizing he is changing into to someone he isn't. He Is questioning why he was having doubts as that was what he had wanted to achieve In the first place.This obscurity in how Robert feels about becoming a new self helps the Idea that change Is a recurring theme throughout the text. In another scenario, Robert Is responding to his dad why he has not been playing or hanging around with Nelson anymore. In this quote, â€Å"He's not really a friend anymore. † Robert replied with a tone that seemed he was trying to tell himself how he ‘felt' instead of his father. The doubt he is experiencing emphasizes he is trying to turn over a new leaf in order to fit in, and hence Robert deals with change throughout the text.Another significant theme recurring through the text is racism. This is shown in the quote, â€Å"He's using his color to his advantage†. The metaphor used suggests that the author is putting out the fact that racism was still a major i ssue in those times and needed to be viewed differently. Ivan is disgusted by Nelson, who he says is using is color to his advantage because blacks in those time were viewed as the unfortunate. The harsh meaning behind this racist comment, gives people an urge to change and make a difference In racial equality.Van's character persists to tell the readers he does not appreciate the ‘blacks' and always finding a reason to hate on them. This is shown in the line † No, special. He's black. † The italics used for the word, ‘special' emphasizes racial equality is not evident in this text. The composers use of a metaphor shows the scorn and harsh personality of Ivan and thus engages the audience in the relevant issues of society. In conclusion, change and racism are significant themes in the text which are sadly still relevant now in our society.The change in Roberts character gives the reader's a personal insight on how these relevant ideas involving post-colonial Zanzibar, affect people negatively. It is responsible for the portrayal of all the characters in ‘Out of Shadows'. Out of Shadows Essay – Themes By Gregariousness relatable in society. The text being explored is â€Å"out of the Shadows† by Jason Lorene with Ivan and his friends. At the beginning of the text, Out of the Shadows by lasso Wallace, Robert has an awkward confrontation with his ex-friend Nelson when isn't.He is questioning why he was having doubts as that was what he had wanted to achieve in the first place. This obscurity in how Robert feels about becoming a new self helps the idea that change is a recurring theme throughout the text.

Is Hong Kong an Ideal Place

Is Hong Kong an ideal place? According to the Global Urban Competitiveness Report (2007-2008) Hong Kong dropped 7 places to 26 as a competitive city for investment. If it's any consolation, Hong Kong remained one of the most affluent cities in the world and one of the top 5 in Asia in term of economy, infrastructure and freedom of speech. Yes, Hong Kong is undoubtedly achieved so well with flying color, having a stable economy, good job market and good accessibility to anywhere due to intra-city transport network. However, the quality of life in this cosmopolitan city does not completely meet the expectation of its people in terms of social, economical and environmental indicators. Firstly, Hong Kong is particularly shot of flat land for building purpose. Owning to the scarcity of land and the large population, housing has often been a grave problem in Hong Kong. Indeed, many Hong Kong people aspire to own a better home. However, due to spiraling rent and house prize, more and more people are unable to afford the high value. Sandwich class suffers the most. As they are not eligible to public housing, the only choice for them is to endure extremely high prize. Reasonably good housing accommodation within the means of the average Hong Kong people is often seriously lacking—- the government should exert themselves. Secondly, serious air pollution spoils the quality of our life and threatens our very existence. In fact, the problem of air pollution has been particularly acute in recent year and the number of days with foggy condition per year also increases. Those lingering exhaust fumes leave a bad impression on the minds of visitors. This turn down the tourism industry, as they are unsatisfied the view of the Victoria Harbour. Thirdly, as Hong Kong follows a â€Å"small government† traditional thinking, one of the important reasons for having an unprecedented surplus is a simple tax system and lower tax rate, attracting businessman to invest and tourists to spend here. Behind the government’s bumper harvest, a large demand to share the fruits of economic development is pushing on Financial Secretary. After the fiscal budget is launched, the policy remains the same as the previous budget, showing that they have no sense of improving the quality of living of the citizens and strengthen the competitiveness of Hong Kong. Hong Kong has best of the west and east blended here. Hong Kong people are proud of having such advantages. When the housing problem and air pollution are solved, Hong Kong will surely become a more stable and prosperous city. Hong Kong government should take more concern from society to get benefits from flourishing economy.

Fuzzy Logic with Data Mining with respect to Prediction and Clustering Research Paper

Fuzzy Logic with Data Mining with respect to Prediction and Clustering - Research Paper Example According to Jemal and Ferlay (2004, p.69), breast cancer is currently one of the major health problems as well as the leading cause of death amongst women worldwide. Consequently early detection of cancer risks is one of the key ways of improving the prognosis of the disease. Although there are a number radiological techniques such as mammography that can be used in the early detection of breast cancer risks, the enormous data generated by these techniques often make it difficult for radiologists to accurately evaluate breast cancer data (Dorf and Robert, 2001, p.234). Artificial intelligence techniques such as fuzzy clustering algorithms can therefore significantly improve the diagnosis and evaluation of breast cancer risks through clustering of the particular data elements. Consequently the incorporation of fuzzy logic algorithms in data mining is a powerful tool that can be employed in the extraction, clustering, quantification and analysis of the data base information regarding the assessment and diagnosis of cancer risks. When dealing with uncertainties in databases, fuzzy logic clustering algorithms can be used to cluster different elements of data into various membership levels depending on their closeness (Castillo and Melin, 2008, p.94). For example, during the evaluation of breast cancer risks, mammogram data may possess some degree of fuzziness such as ill defined shapes, indistinct borders and different densities. In this regard, a fuzzy clustering algorithm can be one of the most effective ways of handling the fuzziness of data related to breast cancer. As an intelligent technique, Fuzzy logic data mining algorithms not only provide excellent analysis of the data but can also be used to develop accurate results that are easy to implement. One of the greatest potential advantages of incorporating fuzzy logic in data mining is the fact that such algorithms can significantly be used in the modeling of inaccurate, non linear and complex data systems b y implementing human knowledge and experience as a set of fuzzy rules that uses fuzzy variables for inference purposes (Nguyen and Walker, 2003, p. 96). For example when using fuzzy algorithm for the prediction and clustering of breast cancer data, the human experience and knowledge related to breast cancer risks can be expressed as a set of inference rules of deduction that are then attached to the fuzzy logic system. Another important advantage of fuzzy algorithms systems for prediction and clustering of breast cancer data is that they usually have a significantly high inference speed. This paper proposes a fuzzy clustering algorithm that can be used in the data mining of breast cancer data and consequently in the evaluation and prediction of cancer risks in patients with suspected cancer cases. Proposed single If-then fuzzy rule Assuming that we have a classification problem with an n-dimensional c-class pattern whose space is given by n-dimensional cube (0, 1), n as well as that the m patterns Xp=Xp1,†¦Xpn, where p=1,2,†¦..m, we will need to generate the fuzzy if then rule in which Xpi [0,1] for p=1,2,†¦., m, i =1,2,†¦..,n. Based on the proposed single fuzzy If-then rule that is based on the mean and standard deviation of the attribute values, the fuzzy rule will be generated for each of the classes. Consequently the fuzzy If then rule for the kth

Baptism in Fifth Business Essay Example | Topics and Well Written Essays - 1000 words

Baptism in Fifth Business - Essay Example This idea did not take hold in the religions of the Graeco-Roman world, but firmly established itself in Judaism. It is from there that baptism became an important part of the Western tradition.   Ã‚  According to the Hebrew Bible a person can become 'unclean' for the purposes of performing various rituals by contact with certain substances vile in the opinion of ancient Hebrew priests, for example semen (Lev 15:13-17) or menstrual blood (Lev 15:19-30). In some way this must have begun as a practical consideration, but it soon took on a more symbolic use as the practical action became a ritual, and the logic of the ritual became more extensive. The high priest was able, through analogy, to be baptized for the entire community and wash away their sins which rendered them unclean for ritual purposes and thus unfit for worshiping Yahweh (Lev 16:24).   Although this ritual action of baptism has a metaphorical basis, it remained part of the 'nuts and bolts' of religious action. Christ ianity moved it to a different sphere. Although the program of John the Baptist is far from clear, he seems to have carried out the traditional baptism for cleaning away the sins of the nation, but believed that the nation as a whole, rather than merely the high priest, had to be baptized (Matt 3; Lk 3; Jn 1:19-36). At some point between John's baptizing and the writing of the Gospels, baptism took on a spiritual dimension so that it would not only wash away uncleanness and sin, preparing one for ritual action, but was meant to transform.

Sutainable operations - industry sector report - Essay Example Therefore, in order to retain its reputation, it implemented varied types of sustainable operations. The industry of aviation is described as one of the fastest growing segment in the entire globe. It is mainly due to the rapid transformation that took place in this sector after liberalization. As a result, the number of passenger as well as cargo airlines increased both in domestic and international levels. This geared the revenue by $ 147.2 billions along with an annual growth of 3 percent in 2011 and 2012. Side by side, the profit margin of the airline industry also enhanced by $ 2.1 billions that helped in contributing a significant portion to the gross domestic product (GDP) and gross national product (GNP). So, aviation industry presented a significant impact over the economic condition of the country as compared to others. The aviation industry is one of the most innovative one that connects individual and countries from one place to another. However, inspite of such positive effects, it is facing varied types of challenges. All of them are mentioned below: Effect of green houses gases (GHG) - due to the emission of varied types of poisonous gases such as carbon monoxide, carbon dioxide, nitrogen dioxide, sulphur dioxide and other air polluting gases, traps the outgoing sources of energy emitting from the lower surface of the ground thereby increasing its temperature as a whole. Depletion of ozone layer - due to the emission of varied types of harmful gases, the level of ozone is depleting day by day to a significant extent. Due to which, the rate of harmful ultra-violet rays are entering into the surface of the earth thereby making presenting varied types of disorders within the human beings. Aircraft noise pollution- aircrafts are also a prime reason for generating huge rate of noises thereby disrupting the general live of the society

History - Essay Example This is one of those moments that redefined the status of the country as one of the biggest economic powerhouses of the world. It also brought into existence, a large number of fiscal and monetary policies that have been a guiding light for the other economies. During the period of 1920’s, there was a period of great turbulence as the growth among the various sectors was uneven. The period was marked by fall of the farm prices, whereas the industrial profits grew. There was an inflated stock market, which led to the Great depression of 1929. The unemployment increased from three percent in the year of 1929, to almost twenty five percent by 1925. The production fell by one third. These led to large scale reforms in the American economy in the form of a lot of new path breaking laws (the social security Act, Works progress Administration Act, The emergency Banking Act and the Economy Act) (Bordo et al, 1998). World War II The World War II was one of the most defining moments in the history of the United States. Categorically, America had always tried to stay away from the war and had tendered its ideological support to the allies. The main contribution of the US to the war was resources, men, money, and ammunition. That actually triggered to the rise in the GDP.

Multinational Strategy adopted by Coca Cola Essay

Multinational Strategy adopted by Coca Cola - Essay Example When companies become multinationals they tend to experience high degree of strategic tension. The MNCs drive for economic growth as well as success tends to pull the companies towards exploitation of the global economies of scale and scope through various operations that gets integrated on the global basis. In addition, the need of acceptance of the companies in its local country tends to make them more responsive towards national differences and policies (Root & Visudtibhan, 1992, p. 42). The multinational enterprise also known as MNEs owns as well as control the income generating assets globally and at least one fifth of the global output. In UK, one third of the company’s profit is derived from overseas operations. MNEs usually comprises of a relatively small number of large enterprises. The growth of the multinational enterprises is seen as a genuine activity of multinationals which included countries like United Kingdom, Japan, Switzerland, Germany, France and Netherland s (Sutton, 1980, p. 86). It is the pressure of globalization which has led companies to manufacture, design and market its products on a global basis. Pressure with respect to globalization generally arrives from company’s domestic and also foreign competitors who tend to challenges the company in each and every segment of the market where it operates. When the pressure is high, companies need to build facilities in the international countries and thus create an international network in those countries (Miltenburg, 2005, p.165). The company chosen for analyzing the multinational strategy is the Coca Cola Company. The company has been widely recognized as being one of the biggest multinational companies. The mission statement of Coca Cola states that the company strives to refresh the globe, inspire the moments of happiness and optimism and hence create value with an intention to make a difference (The Coca Cola Company, 2012). Analysis of multinational strategy Multinational strategies are mainly used when there exists a high pressure due to local responsiveness and globalization. Companies establish factories in those countries where the demand for its product are relatively high as compared to other countries. Mainly joint ventures and acquisitions are used to gain entry to the foreign country. Therefore when pressure due to globalization is high companies follows a special form of multinational strategy known as the transnational strategy (Miltenburg, 2005, p.166). Significant drivers and financial factors The significant drives for multinational strategy of companies can be categorised into various drives which leads to globalisation. Drivers are the factors, which has the ability to give rise to the required needs in the process of global strategy and they are divided into four main groups (Jane, et.al, 2005, p. 283). The drivers include, market drivers, cost drivers, competition drivers and government drivers. The market drivers for coke, which be longs to the soft drinks industry, would be medium in case of global strategy as Coke tends to have global customers and the customers need are also high for its products. Government globalisation drivers can be regarded as high in case of Coca Cola, because it is related with the political conditions of the operating countries. If the government policies and the company policies do not match, it would prove to be a big problem for the firm to operate internationally. Cost drivers for Coke would be low due to the

Secondly, the defense mechanism which is so common to everyone but some of us are not aware of doing and expressing it. I have a certain behavior on which I tend to tell a lie in reasoning and answering to other’s questions and even in my initial reactions. And sometimes, I am also unaware that I did things which were not meant in a certain activity but I still did it to elude from shame and to protect my ego as well. In addition to the example above, I had also experienced the sleep-talking and sleep-walking which I also think it was being influenced by my unconscious thought process, considering that I am deeply asleep on those times. I have clearly observed that almost a hundred percent of my actions and behaviors were determined by my conscious thought4 process and mental awareness, while a fraction of it were influenced by my unconscious mind when I am awake. And it was so obvious that most of us are thinking and are aware before the actions, emotions, sensations, and thoughts are expressed, because if the unconscious thought process dominates over the consciousness of our mind, then our mental awareness are being suppressed, thus, causing mental abnormality. Based from Aswers.com, the slip of the tongue, dreams and other neurotic symptoms are part of the psychic apparatus which normally don’t enter to one’s awareness, thus, it is determined by the unconscious thought process of our mind. Of the examples I had like, the slip of the tongue and the denial which were used for protecting me from shame were both explained by the proponents of Freudian theory by Sigmund Freud.

Improvements are part of every organization and every discipline and they come into the system with time, without improvement the condition becomes that of stalemate .Areas of improvement involve the internal internet facilities, the aging devices that are in practice which support limited functions, also the staff equipment on individual basis. This is followed by the need for providing training to the staff based on modern tools and techniques. Other areas include the customer relationship which has taken a new shape in recent times with everything being conducted through the digital medium. The currently placed architecture is mostly based on analogue mode of transmission, besides it has limited capacity and those that are of digital medium has a small scope of operations to them and also slow in processing. The modern devices that are available have made things very easy and fast to operate and conduct. These devices are easy in their operations and require less training and educating compared to the past. Slow processor based computers, low capacity possessed hardwares and limited connectivity based systems and connecting devices define the present outlook, which can be replaced by a sleeker, efficient, and reliant set of component in form of modern equipment. Having observed the present state of affairs in the organization, it is being realized that changes are needed; these changes can come in form of properly conducted homework and feasibility studies to determine what exactly is needed and in what proportion, relevant to the budgets and resources

Fruit Ripening Essay Example for Free

Fruit Ripening Essay Placing fruit in a bag will help hasten the ripening for only a few fruits. Most fruits will not ripen (ever) once they have been picked. The only fruits that ripen once theyre picked are bananas, avocados, pears, mango, and kiwifruit. Ripeness in fruits is based on sugar content, not color, thus most tomatoes in grocery stores have no flavor because they were picked green and exposed to ethylene gas to induce color change. Tomatoes are what are known as a climacteric fruit which means theyll change appearance based on climactic conditions but they dont ripen. Yes, they continue to soften but thats simply the process of cell deterioration know as decomposition. Some fruits such as peaches, plums, etc. will seem to develop more sweetness as they sit on the counter but thats because theyre also losing moisture and the residual sugars are concentrating in the cell walls. Placing fruit in a paper bag helps to concentrate the levels of ethylene gas which is what helps induce the ripening of the above mentioned fruits (bananas/avocados, etc.). In fact, avocados and pears must be picked in order to ripen. Pears that are left on the tree will simply rot. As mentioned previously brown paper bags used to be something everyone had around their house so it was a commmon item before the switch to plastic bags. Have you ever noticed some people like red bell peppers and not green ones? The reason is due toripeness. Plant tissues communicate by means of hormones. Hormones are chemicals that are produced in one location that have an effect on cells in a different location. Most plant hormones are transported through the plant vascular system, but some, like ethylene, are released into the gaseous phase, or air. Ethylene is produced and released by rapidly-growing plant tissues. It is released by the growing tips of roots, flowers, damaged tissue, and ripening fruit. The hormone has multiple effects on plants. One is fruit ripening. When fruit ripens, the starch in the fleshy part of the fruit is converted to sugar. The sweeter fruit is more attractive to animals, so they will eat it and disperse the seeds. Ethylene initiates the reaction in which the starch is converted into sugar. Iodine solution binds to starch, but not to sugar, forming a dark-colored complex. You can estimate how ripe a fruit is by whether or not is is darkened after painting it with an iodine solution. Unripe fruit is starch y, so it will be dark.

Health Benefits Of Probiotics Biology Essay

Health Benefits Of Probiotics Biology Essay During the past two decades probiotic micro-organisms have been widely applied in different types of products either as pharmaceuticals, nutritional supplements or foods. Among the latter group fermented dairy products such as probiotic yoghurt are becoming popular in the market and the range of such products continues to expand commercially (Manojlovi , Nedovi , Kailasapathy Zuidam, 2010). An increasing demand for probiotic functional foods is mainly due to the plenty of evidence that exists on the positive effects of probiotics on human health. Together with prebiotics, probiotics are often showed to be effective for the treatment or control of several diseases while the enhancement of the immune system and prevention of diarrhea are the main promising health benefits (Roberfroid, 2000). In developing functional dairy products with probiotics several aspects must be taken into consideration. The main issue is the functional characteristics of probiotics. In order to exert their proposed health effects probiotic bacteria should be present at a certain level in the products therefore; manufacturers must ensure their viability and survival under industrial conditions, during storage and into the final food products. Moreover probiotic bacteria must survive intestinal bile acids and withstand gastric pH of the gastrointestinal tract (Saarela, Mogensen, Fonden, Mà ¤ttà ¶ Mattila-Sandholm, 2000). A number of so-called probiotic yoghurt products are sold however studies have shown that very few meet the FAO/WHO guidelines and their viability is not guaranteed thus several microencapsulation techniques have been developed in order to retain the presence of these organisms into yoghurt matrix and the GI tract. Among these methods, spray coating and gel-particle technologie s are more often used (Champagne Fustier, 2007). Furthermore, a new technology called co-encapsulation which refers to encapsulation of both probiotic bacteria and prebiotics together has also shown to have potential in improving viability of probiotics in yoghurt. The overall objective of this presentation is to look at some of the common microencapsulation techniques that are used in production of probiotic yoghurt and to address some challenges in this high-tech method. Food Science mcgill logo.jpg 2. Probiotics: As defined by FAO and WHO Probiotics are: live micro-organisms which when administered in adequate amounts confer a health benefit on the host (World Health Organization, 2001). This definition shows two significant characteristics of a probiotic product .The first one is that these products should contain live microorganisms and secondly the live microorganisms must be in an accurate amount to exert their health benefits (Yildez, 2009). Micro-organisms must have a number of characteristics before they can be considered as probiotics. These include the ability to survive the gastric acid and bile salts of the gastrointestinal tract, colonising in the intestinal mucosa, lack of pathogenicity and the capacity to exert a health improvement on the host. It is unlikely that any one probiotic strain possesses all of these characteristics however, some beneficial effect on human health must have been demonstrated (Tamime, 2005). Élie Metchnikoff was the first person who reported a correlation between the long life of the Bulgarian peasants and the consumption of fermented dairy products, he mainly related to lactic acid bacteria. Nowadays, the probiotic bacteria used in functional dairy products mainly belong to Lactobacillus and Bifidobacteria genera (Heller, 2001). These bacteria have the ability to improve the microbial balance of the human gut, they antagonize pathogens by making antibacterial compounds and compete for pathogen binding. Their other functions are changing gut pH, simulating immunomodulatory cells and producing lactase (Kopp-Hoolihan, 2001). 2.1. Health Benefits of Probiotics: Probiotics have been at the forefront of the development of functional dairy products due to a wide range of desirable health benefits that they promote. Some of these health claims have been supported by research such as improving intestinal tract health, enhancing the immune system, synthesizing and enhancing the bioavailability of nutrients, reducing symptoms of lactose intolerance, decreasing the prevalence of allergy in susceptible individuals, and reducing risk of certain cancers (Kopp-Hoolihan, 2001; Virender Gill, 2009). Most of the current studies mainly focus on the following areas; inflammatory diseases such as inflammatory bowel diseases (IBS and IBD), allergy and diarrhea.

(1992,1995) Y Ohashi et al.(2002) 2.2. Probiotics in fermented dairy products: 2.2.1. Yoghurt: The consumption of fermented dairy products containing bacterial cultures has long been related to various beneficial health effects, and probiotic cultures have had a long association with these types of products. Yoghurt defined as the product of milk fermentation by Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, has a long history of beneficial impact on the well-being of humans (Elli et al., 2006) which makes it a suitable carrier of Food Science mcgill logo.jpg probiotic strains. There has been a disagreement in considering classical yoghurt as a probiotic product. This disagreement is raised due to the fact that the starter bacteria of yoghurt do not colonize and live in the gastrointestinal system. These bacteria are called transient which means that they do not remain in the GIT for a sufficient time to show probiotic activities; however, they have some beneficial activities. All Streptococcus thermophilus and most Lactobacillus delbrueckii subsp. bulgaricus have a high ÃŽÂ ²-galactosidase activity thus yoghurt consumption improves lactose digestion in people with lactose intolerance disorder; furthermore, yoghurt has high numbers of live starters (Guarner, Perdigon, Corthier, Salminen, Koletzko Morelli, 2007). For these reasons the National Yoghurt Association (NYA) has published a position statement for probiotics in September 2006 that Live and active yoghurt that contains Lactobacillus delbrueckii subsp. bulgaricus and Streptococ cus thermophilus is probiotic food as it provides a beneficial effect related to lactose digestion.(NYA, 2006 ) 2.2.2. Bio-yoghurt: Food industries have been quick to recognize the huge market potential of probiotic bacteria due to the several health benefits provided by them. Adding probiotics as dietary adjuncts to various foods and beverages such as cereal bars, juices, cheese, chocolates and frozen yoghurts is becoming an attractive option for companies that are interested in healthy products (Champagne, Gardner Roy, 2005b). However, the inclusion of probiotics in fermented dairy products plays a principle role as the best carriers of these microorganisms. This is mainly because of the high consumer acceptance of these foods as being healthy and natural carriers of living bacteria. Currently, dairy products especially yoghurtlike products are the largest part of the probiotic market. Around 30% of the global population buys into the probiotic dairy products regularly. Fermented dairy products promote the healthy image of probiotics for three reasons: Fermented dairy products such as yoghurt already have a positive health image. Consumers are familiar with the fact that fermented products contain viable microorganisms. The image of yoghurtlike products as healthful foods makes the recommendation of daily consumption of probiotics easier. Food Science mcgill logo.jpg In recent years one of the most popular dairy products for the delivery of probiotics is bio-yoghurts. This product contains species of Bifidobacterium most commonly Bifidobacterium bifidum and Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus casei among lactobacilli in addition to classical yoghurt culture (Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus) (Talwalkar Kailasapathy, 2004).The probiotic bacteria can be added prior to fermentation, simultaneously with the traditional yoghurt cultures, or after fermentation to the cooled product before packaging. 3. Challenges in the development of probiotic yoghurt: In order to exert their health effects, the Intl. Dairy Federation has recommended that the probiotic bacteria should be at a certain level of at least CFU of live microorganisms per millilitre or gram of product at the time of consumption (Chà ¡varri, Mara à ³n, Ares, Ibà ¡ ez, Marzo Villarà ¡n, 2010; Ding Shah, 2007; Organization, 2001; Shah Ravula, 2000; Sultana, Godward, Reynolds, Arumugaswamy, Peiris Kailasapathy, 2000). However, many studies have shown low viability of probiotics in yoghurt. (Table 3) shows some previous reports on the low viability of probiotics in yoghurt. Table 2: Various studies on poor viability of probiotics in yoghurt Low viability of probiotics in yoghurt

Gender Politics and the Liminality of the Herculean Body Essay

Sophocles’s Women of Trachis11, however, deals solely with the tragic drama occurring on the mortal realm, devoid of any cosmic underpinnings. The play, like Heracles, can be divided into two portions. Unlike Heracles, however, Heracles’s world is divided not so much into the microcosmic and the macrocosmic, but into the masculine and feminine. This division is causal, serving to highlight the tension between the domestic world which values emotion, empathy, and feeling and the heroic world which champions duty, honour, and glory. Despite the evident causality, however, the play is marked by Heracles’s and Deianeira’s seemingly implausible deaths, highlighting the illogical aspect of male and female relations as a whole even outside the striking of the inexplicable cosmic event. In both plays, the Herculean body is the locus of a female tension in which the female struggle at being pushed aside is foregrounded. In Sophocles’s play, Heracles acts like Lycus, ravaging a foreign land in order to marry the king’s daughter.

While Women of Trachis addresses the position of the feminine in a male-dominated warrior society on a microcosmic level, Heracles also highlights the feminine perspective, only on a macrocosmic level. Both plays, thus, foreground the pathos of the individual in the grips of forces beyond their control when conflicting realms meet and erupt. Heracles’s body, in being a liminal space where definitions of the cosmic and divine are blurred, is the site where the individual’s larger struggle is acted out. Unlike Heracles, however, Women of Trachis proposes the idea that humanism cannot save the day unless the very definitions of what is means to be heroic are changed so the young, helpless and the female are taken into account. In order for the king to be a proper king, he has to leave behind his heroic, divine self and â€Å"choose (Amphitryon) (as his) father† (1265).

HIV and AIDS: Public Safety vs. Civil Liberties Essay -- Sexually Tra

When a nation is faced with a deadly epidemic does the country have the right to suspend individual’s rights in order to better protect the welfare of the community? This debate has emerged across the U.S.; many have implemented quarantines with regards to h1n1 virus and other contagious, potentially deadly diseases. This includes but is not limited to isolating individuals infected, closing schools, and shutting down public transportation systems. Others are considering enacting new and controversial rules. â€Å"Since the outbreak of the new flu strain, Massachusetts legislators have sought to pass a law that would allow officials to detain or quarantine someone even when there is uncertainty over the person's exposure to contagious disease. Other states have adopted similar laws in recent years† (Efarti 1). These laws can give states the right to contain persons, violating individual rights for the betterment of society. With the government having the ability to quarantine patients infected with potentially harmful diseases on questions the rights the individual has. Can the country detain HIV victims so that the disease will be eliminated? Should the county detain these infected persons for the safety of the community? This issue is constantly debated; by presenting community safety and personal rights in America one can better understand societal nature.

Forensic science is misleading because it suggests only one type of science is involved, but this is not the case. Forensic investigations can involve virtually any field of science and technology. There are many steps that have to be taken when leading a criminal investigation and investigating a crime scene. Firstly, detectives have to try and figure out why and how a crime was committed. They examine a crime scene looking for information or clues such as fingerprints, weapons, and DNA. They investigate the victims’ history to define why someone would want to harm them. After they have formed a hypothesis, they try to find proof that somebody committed a crime so that they can arrest the suspects. They look at both the cause and the actual evidence of the crime and try to see if their hypothesis makes sense. The suspects then enter the criminal justice system where they are tried using the evidence collected at the crime scene.

Bias- systematic error in design, conduct, or analysis of a study that results in a mistaken estimate 3. 4 enduring epidemiological understandings patterns to their occurrence. These patterns can be identified through surveillance of populations. Examining these patterns of health and disease can help us formulate a hypothesis bout their possible causes. B.A hypothesis can be tested by comparing the frequency of disease in selected groups of people with and without the exposure to determine if the exposure and the disease are associated. When the exposure is hypothesized to have a beneficial effect, studies can be designed in which a group of people is intentionally exposed to the hypothesized cause and compared to a group that is not exposed. When an exposur e is hypothesized to have detrimental effect, it is unethical to intentionally expose a group of people. In these circumstances, studies can be designed that observe groups of free living people with and without the exposure. . One possible explanation for finding an association is that the exposure causes the outcome. Because studies are complicated by factors not controlled by the observer, other explanations also must be considered, including chance, bias, confounding and reverse time order. D.

Carnival Corporation Case Study Essay

Carnival Corporation as the largest cruise line in the world is being a leader and innovator in the cruise line industry. Many of the onboard activities and services were introduced to strengthen the competencies between competitors. The challenges of the Carnival were being overcome by the management with creative and innovative strategies. As a corporate entity, Carnival did not refuse to withdraw money to settle the ocean pollution charged by public. The expansions of cruise line market via acquisition of a few subsidiaries dominate the cruise line in the world. 1. Strengths (internal factors) First, the largest cruise line in the world, as the leader and innovator in the cruise industry (growth from two converted ocean liners into an organization with multiples cruise lines). Second, the belief of management and Board of Directors that the company will grows better. It motivates the employees to work hard. Third, internal grow in term of vessels that approximately ten vessels are under construction. Fourth, employees loyalty (the longest period employees remain in this organization is around eight years) because Carnival management treating well to their employees in terms of wages). Fifth, creative and innovative corporate officers that is ready to face challenges. Sixth, Carnival has operational experience and economic of scales that causing them to have lowest break even point in the same industry. Weaknesses First, in 1972, the speed of ship was slow. Second, the long-term debt within 1999 and 2001 is increased (the payback of debt may lower the revenue and thus decreasing the dividend payment for shareholders). Third, the expand market (business) of Carnival causing the difficulty in managing the business. Fourth, reducing on net income in 2001 is because of higher costs and expenses. 2. Opportunities (external factors) First, the expansion through acquisition can reduce the competitors in same industry and has the ability to compete with other competitors (lower advertising costs). Second, collaboration with travel agents can promote cruises. Third, the industry is expected to have bright future in passengers, consolidation through mergers, buyout, and smaller cruise operator failure, and the expansion of the industry worldwide. Fourth, expand of target customers from older people to younger people. Fifth, expand of onboard activities (casino, disco, and nightclub). Threats First, terrorist events that were happen in 11 September 2001. Second, negative publicity in 2002 where Carnival subjected by the ocean pollution charges and â€Å"Norwalk-like† virus that affect the cruise industry. Third, the increased of fuel costs and airline costs that affect the industry. Fourth, the failure of Carnival discontinued operations of Fiesta marina Lines that affect the company image. Fifth, Persian Gulf War that was increased competitors in the cruise industry especially in Caribbean area. Sixth, Royal Caribbean Cruise Lines had institute a major shipbuilding program that challenges Carnival. The emergence of Walt Disney Company in the cruise market; and the prospect of new ships on the horizon give impact to the â€Å"family† cruise vacation segment. 3. Core competencies Yes, Carnival has core competencies because it is the competency crosses divisional boundaries, Carnival can do exceedingly well, and must continuously reinvest in it: i) Adding diversion onboard – such as disco, nightclubs, casino, and others. Carnival also tries to attract younger cruisers by providing vacation package that included airfare to the port of embarkation and home after the cruise. ii) Product positioning – Carnival believes that cruise market comprised to three segments (contemporary, premium, luxury) with different passenger demographics, characteristics, and growth requirements. iii) Travel agents – collaborate with travel agents to promote cruises. Carnival also training travel agents from nonaffiliated travel firm to sell cruises. 4. Distinctive competencies Yes, Carnival has distinctive competencies because distinctive competency is the superior to those of the competitions and difficult for competitors to compete with Carnival: i) Investment in new ships – Carnival is expanding its internal growth by investing in new ships. The ships under constructions are around 10 vessels. It is difficult for other competitors to invest in these large numbers of ships in same period but Carnival can do. ii) External expansion through acquisitions – Carnival has five subsidiaries that control the major cruise lines in different countries. This causing Carnival becomes as the largest cruise line in the world. 5. What trends are emerging in cruise industry?  i) The adding diversion onboard such as planned activities, disco, nightclubs, casino, and other forms of entertainment activities (different kinds of activities that suitable for different ages of target customers). ii) Moderate priced vacation for younger cruisers that included airfare to the port of embarkation and home after the cruise. iii) All inclusive packages that began with bags were tagged for the ship at the airport, air-conditioned bus, meals, onboard activities, house keeping service, until passengers were transported back to airport. iv) Love story movie such as â€Å"Titanic† and â€Å"Love boat† that promote the romance onboard encouraging couples to join cruise. 6. Marketing strategy i) Price – moderate price (vacation packages) that middle-class clients afford to pay. Prices for different levels of rooms are charged according to the customers needs. ii) Product – vacation package that suitable for the clients aged. Other onboard activities such as casino and disco. The service from picking up the clients at airport to board and dropping clients again at airport. iii) Place – Caribbean ports and other destination such as Walt Disney World, Holland, and Costa, as long as the clients want to go. iv) Promotion – some of the promotions are done by travel agents. The â€Å"Fun Ship† cruise that with designated shipboard party and everyone is welcomed by Carnival is another success promotion. 7. The importance of travel agents The travel agents will help Carnival to promote the cruises as an alternative to Disney or European vacation. For people who never take a cruise in their life, or afraid of taking a flight to the destinations will be attracted. Thus, it shows that the important role of travel agents to Carnival. Besides that, not only attracting clients to take a cruise as the core business, selling cruise is also part of the Carnival business. Thus, Carnival is training travel agents from nonaffiliated travel firms to sell cruise. Because of the attractive benefit in term of money provided by Carnival, in year 2000, Carnival took reservations from about 29000 travel agencies to promote the business. And, it proves that this strategy in promoting cruises either to attract clients boarding the cruise or selling the cruise is succeed. 8. Flight or cruise? We will choose cruise because we have not travel yet to some where by cruise before. i) In our opinion, although the price for a cruise might be higher a bit than to take a flight to Caribbean island that we can afford to pay. By choosing a package for the cruising is worth because there will be variety of services that suitable for us as active younger cruisers rather than just to sit in the flight and we have nothing to do. ii) Even though cruise may take a longer time to reach Caribbean island, the final destination that we will reach is Caribbean island no matter we take a cruise or flight. Thus, we can enjoy the onboard facilities that we have paid for. Disco, nightclubs, gym room, cinema, and casino are the places that we seldom go for but we can enjoy if we take a cruise for this vacation. iii) Cruise is a place that we can relax ourselves since the purpose of travel is to relax our mind. The sea view from a ship can make us happy and reduce our stress. On the other hand, we c an also meet some new friends through this trip. iv) Besides, we can experience some exotic destinations when the cruise will sail in the ports. The cruisers can come down from the vessel and visit some famous spots. Adversely, if we take flight, we can’t visit anywhere except just transit in airport. 9. Evaluation of Carnival’s targeting to specific target market i) Contemporary segment – served by Carnival ships, featured a casual ambiance. ii) Premium segment — served by Holland America, for longer market and appealed to more affluent consumers iii) Luxury segment – served by Seabourn and Cunard, catered to experience cruisers. The above are the target market for Carnival. Each segment has different types of costs to be charged to consumers. For the contemporary segment, it is more suitable for family and people who need relaxing during a short period of holidays. The price is cheaper than premium or luxury segment. For the premium segment, it is more suitable for affluent consumers, who need a longer period to relax. It normally targets an older people to board because the facilities in the ship are more suitable for their ages. This segment of cruise will have more cabin or public space per person. In term of price, it is the most expensive and little people can afford to pay. The price for this segment is higher than contemporary segment. Not everyone will prefer this segment of cruise because they need to consider the available time for taking the cruise. The luxury segment targets for extremely rich consumers where they were served as â€Å"king† and â€Å"queen† in the ship. The consumers who taking this segment of cruise can show that they have a higher social status and prestige is the main consider by consumers. 10. Strategic management in Carnival Carnival has a very unique and successful strategic management in cruise industry. During terrorist events in 2001, the world cruise industry was negatively impact by it. However, to overcome this problem, Carnival offered a deep discount to lure back the passengers. In year 2002, Carnival was subjected to the ocean pollution charges. The company was withdrawing $18 million to overcome this issue. This strategy is not only to overcome the issue ethically but also to maintain the company image. Carnival is doing well in pricing strategy where they offer different kinds of packages with moderate price for different kinds of customers. To improve the core competency of the company, Carnival tried to increase the services onboard and adding diversions onboard. Even though other cruise company can imitate this strategy but Carnival is the first to invent the same strategy that succeeds to gain revenue from it. Carnival tried to introduce new strategy to make more convenience to consumers such as the â€Å"all-inclusive package†. The main purpose of this strategy is to maximize the satisfaction of consumers on Carnival services. Finally, to reduce the competition in cruise industry and to compete with other competitors in the same industry, Carnival did acquisition on many cruise lines as subsidiaries. The expansion of Carnival in cruise line market through acquisition can tighten the status of Carnival in cruise industry. 11. The advantage of being a CFC The individuals (foreigners or locals) who held the stocks of Carnival under the CFC status are incorporation exempt shipping operations of United States persons from income tax. Carnival with all of its income (except of United State source of income from transportation, hotel and tour business of Holland America) would be exempt from United State federal income taxes at the corporate level. This exemption not only can increase the revenue of Carnival, it also allows the company to have more funds (liquidation assets) to run more projects or activities for the company. The reason of government to give exemption to Carnival is because to encourage this industry to growth and attract more passengers boarding on ship, especially the ship with casino. It will increase the government sources of money. 12. How to maintain low costs, high level of service? i) Vertical integration or outsourcing – Carnival can try to produce in-house or outsource the products or services in related industries such as shipbuilding, meal preparation industry, and transportation (bus). This is because either vertical integration or outsourcing, which contributes the lowest cost, will be the choice of Carnival to either produce in-house or to outsource the needs. The good relation with suppliers can guarantee the best quality of the products or services. The in-house produce (vertical integration) can guarantee for the high level of products and services quality. ii) Maintain employees – Experienced employees can be the senior for the new comers. They can train and guide the new workers while doing a task rather than the company to send them for training course. Thus, maintaining experienced employees can save the labor cost and maintain the service quality to passengers. iii) Maintain crui se standard (such as sanitary standard) by periodically checking to avoid break down during cruising and it may need higher cost to repair and bring inconvenience to passengers. Conclusion The success of Carnival is depends on the innovative Board of Directors and management. The growth of cruise market becomes more significant because of the low fares high quality of service. Carnival is dominating the cruise line market but they still do investment in improving the services so that to avoid the core competencies become the weaknesses of the company. Even though the net profit of year 2001 is decreased but it did not mean that they have weak internal control. External factors such as increased in fuel cost also are considered the factor in the declining profit. Finally, Carnival has the potential to grow in cruise line market because they already gained the experience in cruise line and they have strong financial to support many cruise activities.

Assessment Of Learning Essay

Assessment of learning refers to strategies designed to confirm what students know, demonstrate whether or not they have met curriculum outcomes or the goals of their individualized programs, or to certify proficiency and make decisions about students’ future programs or placements. It is designed to provide evidence of achievement to parents, other educators, the students themselves, and sometimes to outside groups (e. g. , employers, other educational institutions). Assessment of learning is the assessment that becomes public and results in statements or symbols about how well students are learning. It often  contributes to pivotal decisions that will affect students’ futures. It is important, then, that the underlying logic and measurement of assessment of learning be credible and defensible. TEACHERS’ ROLES IN ASSESSMENT OF LEARNING Because the consequences of assessment of learning are often far-reaching and affect students seriously, teachers have the responsibility of reporting student learning accurately and fairly, based on evidence obtained from a variety of contexts and applications. Effective assessment of learning requires that teachers provide †¢ a rationale for undertaking a particular assessment of learning at a particular  point in time †¢ clear descriptions of the intended learning †¢ processes that make it possible for students to demonstrate their competence and skill †¢ a range of alternative mechanisms for assessing the same outcomes †¢ public and defensible reference points for making judgements Rethinking Classroom Assessment with Purpose in Mind †¢ 55. The purpose of assessment that typically comes at the end of a course or unit of instruction is to determine the extent to which the instructional goals have been achieved and for grading or certification of student achievement. (Linn and Gronlund, Measurement and Assessment in Teaching ) Reflection: Think about an example of assessment of learning in your own teaching and try to develop it further as you read this chapter. 56 †¢ Rethinking Classroom Assessment with Purpose in Mind Chapter 5 †¢ transparent approaches to interpretation †¢ descriptions of the assessment process †¢ strategies for recourse in the event of disagreement about the decisions. With the help of their teachers, students can look forward to assessment of learning tasks as occasions to show their competence, as well as the depth and breadth of their learning. PLANNING ASSESSMENT OF LEARNING The purpose of assessment of learning is to measure, certify, and report the level  of students’ learning, so that reasonable decisions can be made about students. There are many potential users of the information:†¢ teachers (who can use the information to communicate with parents about their children’s proficiency and progress) †¢ parents and students (who can use the results for making educational and vocational decisions) †¢ potential employers and post-secondary institutions (who can use the information to make decisions about hiring or acceptance) †¢ principals, district or divisional administrators, and teachers (who can use the information to review and revise programming). Assessment of learning requires the collection and interpretation of information about students’ accomplishments in important curricular areas, in ways that represent the nature and complexity of the intended learning. Because genuine learning for understanding is much more than just recognition or recall of facts or algorithms, assessment of learning tasks need to enable students to show the complexity of their understanding. Students need to be able to apply key concepts, knowledge, skills, and attitudes in ways that are authentic and consistent with current thinking in the knowledge domain. What am I  assessing? Why am I assessing? Rethinking Classroom Assessment with Purpose in Mind †¢ 57 Assessment of Learning In assessment of learning, the methods chosen need to address the intended curriculum outcomes and the continuum of learning that is required to reach the outcomes. The methods must allow all students to show their understanding and produce sufficient information to support credible and defensible statements about the nature and quality of their learning, so that others can use the results in appropriate ways. Assessment of learning methods include not only tests and examinations, but  also a rich variety of products and demonstrations of learning—portfolios, exhibitions, performances, presentations, simulations, multimedia projects, and a variety of other written, oral, and visual methods (see Fig. 2. 2, Assessment Tool Kit, page 17). What assessment method should I use? Graduation Portfolios Graduation portfolios are a requirement for graduation from British Columbia and Yukon Senior Years schools. These portfolios comprise collections (electronic or printed) of evidence of students’ accomplishments at school, home, and in the community, including demonstrations of  their competence in skills that are not measured in examinations. Worth four credits toward graduation, the portfolios begin in Grade 10 and are completed by the end of Grade 12. The following are some goals of graduation portfolios: †¢ Students will adopt an active and reflective role in planning, managing, and assessing their learning. †¢ Students will demonstrate learning that complements intellectual development and course-based learning. †¢ Students will plan for successful transitions beyond Grade 12. Graduation portfolios are prepared at the school level and are based on specific Ministry criteria and standards. Students use the criteria and standards as guides for planning, collecting, and presenting their evidence, and for self-assessing. Teachers use the criteria and standards to assess student evidence and assign marks. There are three major components of a graduation portfolio: 1. Portfolio Core (30 percent of the mark). Students must complete requirements in the following six portfolio organizers: arts and design (respond to an art, performance, or design work); community involvement and responsibility (participate co-operatively and respectfully in a  service activity); education and career planning (complete a graduation transition plan); Employability skills (complete 30 hours of work or volunteer experience); information technology (use information technology skills); personal health (complete 80 hours of moderate to intense physical activity). 2. Portfolio Choice (50 percent of the mark). Students expand on the above areas, choosing additional evidence of their achievements. 3. Portfolio Presentation (20 percent of the mark). Students celebrate their learning and reflect at the end of the portfolio process. ( Portfolio Assessment and Focus Areas: A Program Guide) 58 †¢ Rethinking Classroom Assessment with Purpose in Mind Chapter 5 Assessment of learning needs to be very carefully constructed so that the information upon which decisions are made is of the highest quality. Assessment of learning is designed to be summative, and to produce defensible and accurate descriptions of student competence in relation to defined outcomes and, occasionally, in relation to other students’ assessment results. Certification of students’ proficiency should be based on a rigorous, reliable, valid, and equitable process of assessment and evaluation. Reliability  Reliability in assessment of learning depends on how accurate, consistent, fair, and free from bias and distortion the assessment is. Teachers might ask themselves: †¢ Do I have enough information about the learning of this particular student to make a definitive statement? †¢ Was the information collected in a way that gives all students an equal chance to show their learning? †¢ Would another teacher arrive at the same conclusion? †¢ Would I make the same decision if I considered this information at another time or in another way? Reference Points Typically, the reference points for assessment of learning are the learning  outcomes as identified in the curriculum that make up the course of study. Assessment tasks include measures of these learning outcomes, and a student’s performance is interpreted and reported in relation to these learning outcomes. In some situations where selection decisions need to be made for limited positions (e. g. , university entrance, scholarships, employment opportunities), assessment of learning results are used to rank students. In such norm-referenced situations, what is being measured needs to be clear, and the way it is being measured needs to be transparent to anyone who might use the assessment  results. Validity Because assessment of learning results in statements about students’ proficiency in wide areas of study, assessment of learning tasks must reflect the key knowledge, concepts, skills, and dispositions set out in the curriculum, and the statements and inferences that emerge must be upheld by the evidence collected. How can I ensure quality in this assessment process? Rethinking Classroom Assessment with Purpose in Mind †¢ 59 Assessment of Learning Record-Keeping Whichever approaches teachers choose for assessment of learning, it is their records that provide details about the quality of the measurement. Detailed records of the various components of the assessment of learning are essential, with a description of what each component measures, with what accuracy and against what criteria and reference points, and should include supporting evidence related to the outcomes as justification. When teachers keep records that are detailed and descriptive, they are in an excellent position to provide meaningful reports to parents and others. Merely a symbolic representation of a student’s accomplishments (e. g. , a letter grade or percentage) is inadequate. Reports to parents and others should identify the  intended learning that the report covers, the assessment methods used to gather the supporting information, and the criteria used to make the judgement. Feedback to Students Because assessment of learning comes most often at the end of a unit or learning cycle, feedback to students has a less obvious effect on student learning than assessment for learning and assessment as learning. Nevertheless, students do Ho w can I use the information from this assessment? Guidelines for Grading 1. Use curriculum learning outcomes or some clustering of these (e. g. , strands) as the basis for grading. 2.  Make sure that the meaning of grades comes from clear descriptions of curriculum outcomes and standards. If students achieve the outcome, they get the grade. (NO bell curves! ) 3. Base grades only on individual achievement of the targeted learning outcomes. Report effort, participation, and attitude, for example, separately, unless they are a stated curriculum outcome. Any penalties (e. g. , for late work, absences), if used, should not distort achievement or motivation. 4. Sample student performance using a variety of methods. Do not include all assessments in grades. Provide ongoing feedback on formative  performance using words, rubrics, or checklists, not grades. 5. Keep records in pencil so they can be updated easily to take into consideration more recent achievement. Provide second-chance assessment opportunities (or more). Students should receive the highest, most consistent mark, not an average mark for multiple opportunities. 6. Crunch numbers carefully, if at all. Consider using the median, mode, or statistical measures other than the mean. Weight components within the final grade to ensure that the intended importance is given to each learning outcome. 7. Make sure that each assessment meets quality standards (e.g. , there should be clear targets, clear purpose, appropriate target-method match, appropriate sampling, and absence of bias and distortion) and is properly recorded and maintained (e. g. , in portfolios, at conferences, on tracking sheets). 8. Discuss and involve students in grading at the beginning and throughout the teaching and learning process. (Adapted from O’Connor, How to Grade for Learning ) Resource: Marzano, Transforming Classroom Grading 60 †¢ Rethinking Classroom Assessment with Purpose in Mind Chapter 5 rely on their marks and on teachers’ comments as indicators of their level of  success, and to make decisions about their future learning endeavours. Differentiating Learning In assessment of learning, differentiation occurs in the assessment itself. It would make little sense to ask a near-sighted person to demonstrate driving proficiency without glasses. When the driver uses glasses, it is possible for the examiner to get an accurate picture of the driver’s ability, and to certify him or her as proficient. In much the same way, differentiation in assessment of learning requires that the necessary accommodations be in place that allow students to make the particular learning visible. Multiple forms of assessment offer multiple pathways for making student learning transparent to the teacher. A particular curriculum outcome requirement, such as an understanding of the social studies notion of conflict, for example, might be demonstrated through visual, oral, dramatic, or written representations. As long as writing were not an explicit component of the outcome, students who have difficulties with written language, for example, would then have the same opportunity to demonstrate their learning as other students. Although assessment of learning does not always lead teachers to differentiate  instruction or resources, it has a profound effect on the placement and promotion of students and, consequently, on the nature and differentiation of the future instruction and programming that students receive. Therefore, assessment results need to be accurate and detailed enough to allow for wise recommendations. Reporting There are many possible approaches to reporting student proficiency. Reporting assessment of learning needs to be appropriate for the audiences for whom it is intended, and should provide all of the information necessary for them to make reasoned decisions. Regardless of the form of the reporting,  however, it should be honest, fair, and provide sufficient detail and contextual information so that it can be clearly understood. Traditional reporting, which relies only on a student’s average score, provides little information about that student’s skill development or knowledge. One alternate mechanism, which recognizes many forms of success and provides a profile of a student’s level of performance on an emergent-proficient continuum, is the parent- student-teacher conference. This forum provides parents with a great deal of information, and reinforces students’ responsibility for their learning. The Communication System Continuum: From Symbols to Conversations (O’Connor, How to Grade for Learning ) Grades Report cards (grades and brief comments) Infrequent informal communications Parent-teacher interviews Report cards with expanded comments Frequent informal communication Student-involved conferencing Student-led conferencing Reflection: What forms do your reports of student proficiency take? How do these differ according to audience? Rethinking Classroom Assessment with Purpose in Mind †¢ 61 Assessment of Learning An Example of Assessment of Learning. Elijah was interested in assessing student mastery of both the modern and the traditional skills required for survival in the Nunavut environment where he teaches. The overarching theme of survival is taught in the early grades and culminates at the senior level in a course delivered in Inuktitut. Students learn how to take care of themselves and others, and how to adapt what they know to the situation at hand. Survival requires not only skills and knowledge, but also a concept the Inuit people call qumiutit, or the ability in an emergency situation to pull out of stored memory information that will enable a person to cope, not panic. Traditionally, this was learned in a holistic manner, grounded in Inuit traditional guiding principles that were nurtured and developed from birth, and taught and reinforced in daily living. Throughout the term, Elijah took his students to an outdoor area to practise on-the-land survival activities, using both traditional and modern methods. He always took with him a knowledgeable Elder who could give the students the information they needed to store away in case of emergency. The students watched demonstrations of a skill a number of times. Each student then practised on his or her own, as Elijah and the Elder observed and assisted. Elijah knew that students need to have a high level of expertise in the survival skills appropriate for the northern natural environment. Elijah assessed each student on each survival skill (e. g. , making fire the traditional way, tying the knots required for the qamutik cross-pieces on a sled). What am I assessing? I am assessing each student’s performance of traditional and modern survival skills. Why am I assessing? I want to know which survival skills each s tudent has mastered and their readiness to s urvive in the natural environment. 62 †¢ Rethinking Classroom Assessment with Purpose in Mind. Chapter 5 Elijah knew that the best way to determine if students have mastered the skills is to have them perform them. When students believed they were ready, Elijah created an opportunity for them to demonstrate the mastered skill to a group of Elders, who then (individually, then in consensus) determined if the performance was satisfactory. A student’s competence in a survival skill is often demonstrated by an end product. For example, competence in knot tying is demonstrated by a knot that serves its purpose, and competence in fire building is demonstrated by a fire that is robust. As the Elders judged each student’s performance of the skills, Elijah recorded the results. He shared the information with each student and his or her parents in a final report, as shown here. Ho w can I use the informatio n from this assessment? Now that I know which skills each of the students has mastered, I can report this information to the s tudents and their parents. I can use this information to identify a learning path for each s tudent. How can I ensure quality in this assessment process? Ensuring quality with this approach involves clear criteria: either the student performs the skill s uccessfully or does not. I need to provide adequate opportunities for the s tudent to demonstrate the skills under various conditions and at various times. What assessment method should I use? I need an approach in which students can demonstrate the traditional survival skills that they learned. The method I choose should also allow me to identify which skills they did not master.

Elijah’s report identified which of the students had mastered the specified skills required to survive in the Nunavut environment. It outlined other areas (such as adaptability to the seasons and attitudinal influences) about which peers, parents, and family members would need to provide input before a comprehensive assessment could be made. The assessment also identified those students not yet ready to survive in the natural environment. But the Elders did not stop working with the students who did not reach mastery. Elders see learning as an individual path in which skills, knowledge, and attitudes are acquired along the way. If a particular skill was beyond the capability of a student, the Elders identified other areas where that person could contribute to the common good of the community, and was accepted for the gifts he or she brought to the group. In this way, the Elders helped Elijah differentiate the learning path for each of his students.

Sexuality and Disability, 20(3) Fall 2002 Overview: The objective of this study is to investigate the association between sexuality and psychological well-being in people with physical disabilities. 1196 respondents completed the study. Previous studies have suggested that sexual satisfaction and body esteem are important to the overall well-being of people with physical disability. The extent to which sexuality is related to other aspects of psychological well-being, and differs from relationships among the general population, is unknown. Problem: The problem being investigated is the relationship of sexuality (sexual and body esteem and sexual satisfaction) and psychological wellbeing (depression and self-esteem) among people with physical disabilities, and to compare these relationships with those found in able-bodied people. TR: The literature review was comprehensive to investigate the problem for this study. Research question: Can sexuality as a variable be a significant predictor of psychological well-being in both groups of respondents? Can the relationship of sexuality and well-being variables be of similar strength among people with physical disability and able-bodied respondents and in both men and women? Methods and procedures: 1196 subjects were randomly selected from America and Australia ages 18-69 years old and were identified as having physical disabilities. The following instruments were used: Demographic Questions; 21 item Depression, Anxiety and Stress Scale (DASS); 10 items the Rosenberg Self-Esteem Scale; Sexual esteem subscale in Snell and Papini’s; Body Esteem Scale; and Sexual Satisfaction Survey; Multiple Regressions Analysis. Results: Taleporos & McCabe’s (2002) revealed that among people with physical disability, high levels of body esteem and sexual satisfaction predicted high levels of self-esteem (p=

Why do we need so many different theories in accounting Essay - 2

Why do we need so many different theories in accounting - Essay Example The purpose of this paper is to discuss how accounting theories differ from each other including real life examples that show contrasting accounting theories in the real world. Accounting is a simple, yet complex field due to fact that there hundreds of different principles that establish the foundation for its practice. The accounting profession as a whole is self-regulated. There different accounting bodies that set the principles and standards that guide the profession. Two of those governing bodies are the FASB and ICPA. The primary accounting framework that is used by accountants to guide their everyday daily activities are the generally accepted accounting principles (GAAP). The GAAPs covered a wide variety of accounting subjects such as long lived assets, revenue recognition, and inventory topics (Accountingtools). An illustration of how the accounting profession has different treatments or accounting applications for the same economic event can be seen in the way accountants calculate depreciation of assets. Accountants can choose one among various depreciation methods to calculate the depreciation of an asset. Five of the techniques that accountants can use to calculate depreciation are FIFO, LIFO, age-life method, straight, declining balance, and sum-of-the years’ digits method (Weygandt & Kieso & Kimmel, 2002, p.409). The final depreciation calculated by each of these methods gives an output that is different. This might seem a little confusing for a person outside accounting circles, but there is a financial logic behind the existence of so many depreciation methods. The reason there is so many accounting depreciation method is that these methods are available so that accountants can select the method that most appropriate depending on the circumstance. For example an accountant that is auditing a company dedicated to selling

The competition among the key players in this industry is not as aggressive as in other industries. Sony record label is a renowned company in the entertainment industry offering diverse products and services to its wide market as explained by Hanson et al. (2001). Their productions are highly refreshing and entertaining (Sony United 2007). This is achieved by efficiently combining and managing its resources, competencies, and abilities. This results in a strong competitive advantage. Resources are the features owned and managed by a company to create value for customers as stipulated by Hill et al. (2007). The discussion below analyses the different resources owned and managed by the company. These are described as the tangible resources that have physical properties and are financial in nature (Hill et al. 2007). The company recorded an increase in sales of 10% in the year 2007 (Sony United 2007). The company owns other forms of tangible resources in form of land, buildings, machinery, and equipment valued at nearly 14 million dollars (Sony United 2007).

Discussion Questions - Essay Example Keeping the message simple and straightforward is the key to the best forms of communication. In writing resumes, it is imperative to choose the style of resume that best suits the history that will serve your application to a company. In writing a chronological resume, the way in which an individual’s education and employment history can be developed to portray a strong history of personal achievement. This can show a proper progression toward a career goal. A skills resume will develops a picture of the accumulated skills that a potential employee has to offer a new employer. Gaps in the time period in which education and employment experience reaches toward the career goals of this applicant can be deemphasized and an overall picture of attained experience can be shown. When you know that a job position is available, the form of cover letter that should be used is the solicited letter. The solicited letter is in response to an ad, a referral, or used when the expansion of a company is well known and there is availability of a position. The beginning of this letter will state which position is being addressed, where the information that the position was available was attained, and a summary of the qualifications of the applicant should be included. The letter will end with a request for an interview. In a prospecting letter, it is more appropriate to use a bit of creativity to catch the reader’s interest before moving forward with the idea of the job prospect. In this letter, one is seeking to inspire the employer into hiring the applicant, rather than responding to a known possibility of a job In order to tailor a resume and cover letter to a specific company, it is vital to understand the way in which the organization has created its persona as an employer. As an example, the Nike company emphasizes a healthful existence and promotes

Leadership Factors Assignment Example | Topics and Well Written Essays - 750 words

Leadership Factors - Assignment Example I do not believe that the authentic leadership questionnaire is really valid because the answers are too subjective to provide a real understanding of one’s leadership style. Description of My Scores My scores on the Authentic Leadership Self-Assessment Questionnaire (ALSAQ) are as follows: Self-awareness, 13; Internalized moral perspective 17; Balanced processing, 10; Relational transparency 10; with a total of 50. According to Northouse (2013) all of these scores show weakness as an authentic leader when tallied individually. However, when the scores are added together, the final score falls within the high range (Walumbwa and Associates, 2012). When I look at these scores individually and the questions that were added together to create the score, I cannot say that these scores represent me or anyone as an authentic leader. According to Tobias (2011) the area of self-awareness is to measure the personal insights that a leader has and whether they understand their strengths and weaknesses. I scored a 13 in this area but I thought this was not a good indication of my ability. As an example, one of the numbers that determined this measure was number nine which read, â€Å"I seek feedback as a way of understanding who I really am as a person.† If someone seeks feedback from others to know who they are, I would say this is a weak leader. I said this would not describe me at all. In the next section, internalized moral perspective, Tobias (2011) states that this section measures an individual’s moral code and values. It also tells whether an individual has their own control or is controlled by others. I live by my own moral code and I do not allow other people to control how I act or react to situations. I believe this is a better way to live than to have someone else tell you what to do. Tobias (2011) states that the third category, balanced processing, measures critical thinking and the ability to take in information and make decisions after listening to other people’s opinions. Again, I think this is not a true measure of a person. I think it is better to stick to your own ideas, taking other people into consideration, but you must make the decision eventually. Welch and Welch (2012) say that being authentic shows that the individual is likable. I think this is true. People who are open and honest as far as they can be, are people who can be trusted. But, this is a perception and not necessarily a reality because it is based on how someone perceives someone else. Tobias (2011) states that he final section, relational transparency, measures how the leader communicates with others and expects that they will communicate openly and honestly. I scored a 10 on this section. I believe that I communicate well with others, but if I were leading a team, I would not reveal everything about myself to that team. I think that one can be authentic without telling all the details of their life. Implications of the Scores for M y Effectiveness as a Leader I do not think these scores really give an idea of how I would be as a leader. The scores are subjective, which means that I could change my mind about some of the scores and get a better score in the end. I think that these types of scores are like taking any personality quiz or romance quiz that one can find on the Internet. Nothouse (2013) states that this test has not had enough empirical evidence to show that it is valid. I would not take this test seriously if I wanted to know how I would be as
