Color Blindness - Tritanopia essays

Color Blindness - Tritanopia essays Colour Blindness, defect of vision affecting the ability to distinguish colours, occurring mostly in males. Colour blindness is caused by a defect in the retina or in other nerve portions of the eye. Partial colour blindness, called dichromatism, consists generally of the inability to differentiate between the reds and the greens or to perceive either reds or greens; infrequently, the confusion may involve the blues or the yellows. Dichromatism is the most common form of colour blindness, affecting about 7 percent of men and less than 1 percent of women. Dichromatism is identified as a sex-linked hereditary characteristic (Figure 1). A colour blind person has difficulty in distinguishing colours that are on "confusion lines". For example, protanopes confuse blue-greens (and greys) with red (and browns). The deutranopes make mistakes with blue-greens and purple. While tritanopes confuse yellow with blue. The last dichromat group; tetartanopes, confuse yellow with blue. The anomalous types have difficulty with light tints and dark shades. Tritanopia is rare, affecting one in fifty thousand males and one in one hundred thousand females. There are three different types of wave sensitivity cones: long (red), medium (green), and short (blue). Short wave sensitivity (SWS) cones are most sensitive to a wavelength of approximately 419nm. When examining the absorbance curve, long and medium wave sensitivities are close together (30 nm shift), whereas the SWS cone curve is shifted more than 100 nm away S cones are much rarer than long and medium cones, accounting for approximately 5% of the total. When our vision depends on SWS cones alone, our spatial resolution is very poor. Tritanopes have malfunctioning SWS cones. The problem occurs when there is a dominant inheritance of the G79R and S214P mutations this suggests that the abnormal gene products actively interfere with the viability or accuracy of blue ...

Citing an Online Video with Chicago Authorâ€Date Referencing

Citing an Online Video with Chicago Author–Date Referencing Citing an Online Video with Chicago Author–Date Referencing Previously, we looked at how to cite an online video using Chicago’s footnote referencing. But The Chicago Manual of Style also sets out an author–date referencing system. So to make sure we’ve covered all our bases, this time we’re looking at citing an online video author–date style. In-Text Citations First of all, citations. As with any source in Chicago author–date referencing, citing an online video means giving the creator’s surname and a date of publication in brackets: Some museums are now returning stolen artifacts (Colwell 2018). Here, we’re citing a TED Talk by Chip Colwell that was uploaded to YouTube in 2018. We’ve cited Colwell in this case because gives the presentation, but with some videos you may want to cite the writer or director instead. It all depends on who the main creator is. The main difference from citing a print source comes when quoting a video. In the absence of page numbers to cite, you’ll have to include a timestamp for the part of the video cited: Discussing these returns, he describes this as â€Å"plant[ing] seeds of hope in the ruins of the past† (Colwell 2018, 7:18). Here, for instance, we can see that the quote comes from 7 minutes and 18 seconds into the video. Additional source information will then be given in the reference list at the end of the document. Reference List When you add an online video to your reference list, you need to provide enough information for readers to find it themselves. This should include at least most of the following: Surname, First Name. Year of publication. â€Å"Video title.† Host website. Format, video length. Uploader name (if different from creator). Date of access (if required). URL. You might not be able to find all this information, but this is fine as long as the video is easy to identify (keep in mind that URLs sometimes change, so you need more than just a link). To see how this would look in practice, we’ll create a reference for the video cited above: Colwell, Chip. 2018. â€Å"Why museums are returning cultural treasures | Chip Colwell.† YouTube. Video, 13:01. TED. https://www.youtube.com/watch?v=YUUP2MMz7PU. We cite Chip Colwell as the author above, but we also include TED as the uploader. This is because the video is hosted on the TED YouTube channel.

An Introduction to the Supply Chain and the Firm's Position within It Essay

An Introduction to the Supply Chain and the Firm's Position within It - Essay Example Discussion: A Supply Chain may be seen as a series or network of facilities and distribution channels which facilitate the procurement, processing and conversion of raw materials into finished products and their distribution from the place of production to the final customer through a series of distribution stages. The stages are characterized by the distributer at the given stage and the activities that are performed by the distributor to ensure the delivery of the product to the end customer (Wiley 2012). The supply chain usually takes diverse forms. The structure of the firm varies in length, size, shape and the kind of activity involved. Also, a firm may be part of more than one interconnected supply chains, whose final outcome might be differentially diverse (Enporion 2009). Thus the Supply chains may sometimes more appropriately be referred to as Supply networks. For example Kellogg’s the world leading breakfast cereal and snack producer, sources raw materials from diffe rent sources which are functionally as well as geographically diverse. Further, Kellogg’s collaborates with a huge network of distributors like wholesalers, retailers and other outlets like hotels etc to make its product reach to the end customers (The Times 2012). Once the concept of a Supply chain as part of the value chain is established, the concept of Supply Chain Management (SCM) comes to the fore. However it is important to understand the concept of logistics first. Logistics is concerned with Flow of materials and information to and from a firm’s boundaries aiding in the production and distribution of its products to the customers. At the same time, supply chain is a network of companies performing these logistical activities together to bring a product or products to the market. Also, a supply chain, apart from the logistical activities, also includes activities like marketing, finance and customer service. Supply Chain management thus is concerned with the co ordinated activities of production, location and inventory among the various participants of a supply chain. The activities are directed such that a mix of responsiveness and efficiency that is best suited to the market is achieved (Wiley 2012). Supply chain management is therefore concerned with the efficiency and effectiveness of a supply chain. One of the major objectives of a supply chain is to reduce the logistical costs. Also, it strives to achieve an incentive within the system to remove waste from the processes or activities involved. It is through effective Supply Chain management that a firm can achieve the objective of a giving a better and differentiated value to the end customer. Kellogg’s for instance achieves this value through activities like partnering with supermarkets like Tesco. It follows close relationships with such partners. It has come up with a shelf ready unit at Tesco, which helps gives better choice and visibility to customers. Also, it augurs wel l for the sales both for Tesco as well as for Kellogg’s. In the recent years, Supply Chain Management has assumed an increasingly important role. This is so due the increasing globalization and industrial competition. From the perspective of stakeholders of a supply chain

Internship Final paper - Essay Example 13). Firstly, It is imperative to elucidate the fact that an internship gives an individual the chance to build his or her skills. There is a lot of competition in the job market in the contemporary world. Employers are only recruiting the best candidates and hence an internship helps an individual advance his or her skills in preparation for future job interviews and vocations. Some of the skills advanced through an internship include communication skills, ability to work in teams, and time management (WetFeet 13). My duties and responsibilities during my internship included organizing patients application alphabetically, I filled out a sheet of the important patients details particularly name, cell number, date of birth, and email address. Subsequently, my duties included inserting all the important patients details in the system, ensured patient confirmed their appointments, and I also worked at the reception, insurance department, and financial department. Working at the reception involved a lot of communication with the clients and this gave me an opportunity to hone my communication skills. Organizational skills are also important in any vocation. Employees are required to be organized in their work and I was able to sharpen my organizational skills through organizing patients applications alphabetically and filling their important information in the system. Secondly, as mentioned earlier, an internship is an opportunity for an individual to have a taste of the industry in general. In other words, it presents individuals with the opportunity to expose themselves to the day to day running of an organization or institution. It is very easy today to conduct research regarding a particular job or organization through the internet and have an understanding of what the job entails. However, this is incomparable with being a part of a team that aims to achieve specific objectives (WetFeet

The Byzantine Empire Essay Example for Free

The Byzantine Empire Essay When the western Roman Empire descended into chaos in 500 C.E. much of the Roman culture on the west side was lost, while the Eastern empire survived and preserved much of the surviving Roman Culture, but changed it’s name to the â€Å"Byzantine Empire,† showing individuality in many aspects between Rome and Byzantine. The Byzantine Empire was the surviving reminisces of the Roman Empire, which flourished into the oldest and longest lasting empire in our history. It began with the emperor Constantine who based much of the Byzantine Empire social structure of Rome. For example, the romans had two distinct classes, the Patricians and the Plebeians, the poor and the elite. The Byzantines had the poors and the Vassals. Although there was a severe gap between the social classes, the Byzantines had something called a Pepacy or the office of the people. â€Å"The laws of every people governed by statutes and customs are partly peculiar to itself, partly common to all mankind†¦..† This shows that although it continued on the Greek style of democracy, it incorporated its own laws and writings in it (Document 1 and Document 4) When the Western Roman Empire crumbled down, many people don’t know the extent of the damage the Western Empire endured. â€Å"And having a mind set upon evil, they took in hand unlawful deeds, thinking to suppress altogether the depicting of the venerable images.† This displays the chaos and anarchy roaming in Western Rome. And when the Byzantine Empire came about, it was the nail in the coffin, marking the decline of the Roman Empire (Document 3) Originally Roman religion worshipped the emperor as a god, a single deity, however that all changed when Constantine came into power. He quickly established the Byzantine capital as Constantinople, and made Christianity as the national religion. This marked the start of Christian ascendancy, which quickly globalized Western Europe. â€Å"We should be the slaves, not the sons of such as Church, and the Roman See would not be the pious mother of sons but a hard and imperious mistress of slaves.† The following quote depicts many citizens against and the Christian way of life, which eventually switched over to Islam and Constantinople was renamed to modern day â€Å"Istanbul.† (Document 2 and Document 5) If given a bonus document it would explain how people lived day in and day out living in the Byzantine Empire. Because it will explain how much of their daily lives are parallel to that of the ancient Romans.

Ansel Adams :: essays papers

Ansel Adams Ansel Easton Adams was born in San Francisco in 1902, the only child of Charles and Olive Adams. He grew up in a house overlooking the Golden Gate Bridge and had a strong appreciation for beauty. By 1908 Adams was an enormously curious and gifted child, and began a precarious and largely unsuccessful journey through the rigid structure of the public school system. In 1914 Adams taught himself to play the piano and excelled at his serious study of music, however he despised the regimentation of a regular education, and was taken out of school. For that year, his father bought him a season pass to the Panama-Pacific Exposition, which he visited nearly every day, and began to receive private scholastic instruction from tutors. In 1916 Adams convinced his parents to take a family vacation in Yosemite National Park.

Lifeboat Ethics: The Case Against Helping the Poor Essay

Since 1991, the southern half of Somalia, a poverty stricken African nation, has seen various tribal militias battle for dominance and power over individual regions of the country. Violence has plagued Mogadishu, the capital, since warlords ousted the former president. Mere months after the collapse of the government, men, women and children in torn clothes ran helplessly towards packages dropped from military planes towards the hot sand of their tiny village. This action was one of many attempts to help underdeveloped nations receive food by the United Nations’ World Food Programme. Within his article titled â€Å"Lifeboat Ethics: the Case Against Helping the Poor†, Garret Hardin, a well-known philosopher of ecology, analyzes the difficulty and ultimate ruin associated with providing aid to these nations. Hardin’s argument for the preservation of well-to-do societies is embodied by his extended metaphor of each society as a lifeboat, with the citizens of developed nations riding calmly amongst a sea of drowning poverty-stricken individuals. Ultimately, Hardin argues for a very harsh thesis: regardless of the current situation, privileged nations simply should not provide aid to those individuals trapped within the vortex of underdeveloped nations. His argument is consequentialist: he claims that the net result of doing so would be negative and would, in the long run, court large-scale disaster. Although Hardin’s argument appears logic-based, his excessive metaphors fail when applied to real-life scenarios, for oftentimes he misconstrues facts to create a claim that may be perceived as more accurate than reality illustrates. Furthermore, any counter-arguments Hardin feels may refute his claim are pushed aside, avoiding factual evidence that may prove his argument inaccurate or misleading. Much like a lifeboat, Hardin leaves the assertions of the â€Å"humanitarian apologists† to drown so as to avoid the overturn of his claim. Within the section titled â€Å"Adrift in a Moral Sea†, Hardin reveals the lifeboat analogy upon which this essay is almost entirely founded, although shortly after it is presented one can see a loophole he cleverly ignores. The metaphor he creates is, nonetheless, coherent, and is used to describe the limited carrying capacity a lifeboat (rich nations), can hold:So here we sit, say 50 people in our lifeboat. To be generous, let us assume it has room for 10 more, making a total capacity of 60. Suppose the 50 of us in the  lifeboat see 100 others swimming in the water outside, begging for admission to our boat †¦ since the needs of all in the water are the same †¦ we could take them into our boat, making a total of 150 in a boat designed for 60. The boat swamps, everyone drowns. Complete justice, complete catastrophe †¦ we might let 10 aboard, but how do we choose? And what about the need for a safety factor? (1,2)Although logical, this metaphor is undoubtedly dubious. Hardin characterizes the safe and the drowning as rich versus poor nations, though in reality not all countries are deemed on one side of the scale, wealthy or impoverished. Many waver on the edge, needing very little aid to push over into industrialization and development. In relation to Hardin’s metaphor, these nations, in retrospect, require a short ride on the lifeboat before they may swim safely away. Furthermore, Hardin assumes the earth does not hold enough resources to provide for everyone, and although correct in stating we cannot sustain an unlimited number of people, he neglects the very definition of such a word. Exactly how many people are contained within an â€Å"unlimited number†? Hardin disregards any hint as to what this number is, a fairly important point when referencing a depletion of world resources. By disregarding the importance of such a number, Hardin influences the reader to believe helping impoverished nations is impossible, for, after all, an unlimited number of individuals would hardly be feasible. However, if the number of people that could be helped was presented, some may change their minds, recognizing that helping some is better than helping none at all. In knowing this, Hardin however, chooses to eliminate the statistic entirely. Within this scenario Hardin appeals to the readers with the presentation of a circumstance in which only two outcomes seem probable. Either the passengers help ten more individuals and drown, or they neglect to help any, and float securely away with the â€Å"safety factor† still intact. Hardin disregards the idea of helping some people, even if selected in a fairly arbitrary way: â€Å"Suppose we decide to preserve our small safety factor and admit no more to the lifeboat. Our survival is then possible although we will have to be constantly on guard against boarding parties† (2). He insinuates that once the decision is made to help some, the lifeboat passengers must attempt to save all of those drowning, which is clearly not feasible given the carrying capacity of the lifeboat. Although the boat’s capacity should not exceed the  admission of more than ten people, why not admit three, four, or even those ten? It seems rather unreasonable to deny help to every i ndividual, when, although not all can be rescued, the boat clearly holds the space for more. The same ideology may be applied in other philosophical debates, including the death penalty, as we discussed in lecture. Ernest Van Den Haag, a defender of the death penalty, explains in his article that the importance of punishment is not whether every individuals gets what they deserve, but rather that some, rather than none, of the convicted receive their rightful punishment. Professor Yaffe applied this to a smaller-scale, saying, â€Å"If you have three pieces of candy and four children, all equally deserving, it is better, according to Van den Haag, for three to receive their desert than for none to receive what is deserved.† This scenario can easily be applied to Hardin’s lifeboat metaphor. Hardin claims, â€Å"Since the needs of all in the water are the same †¦ since they can all be seen as â€Å"our brothers† †¦Ã¢â‚¬  (1), therefore one cannot reasonably argue the desert of the poverty-stricken varies. As a result, the argument can be made that pulling some into the lifeboat to be saved is far better than leaving all to drown. One may argue ignoring such a possibility serves as a way to avoid criticism from liberals who would quite obviously propose letting some individuals on board. Hardin realizes the difficulty in a rebuttal to this argument, therefore he chooses to leave out the situation entirely. Additionally, the carrying capacity of the wealthy nations is far underestimated, and entirely misleading, within this metaphor. Hardin’s philosophy regarding the swamping of wealthy nations does not seem remotely accurate when the feeding of underprivileged nations costs very little in relation to the finances of developed nations. According to past statistics provided by the Index of Global Philanthropy, â€Å"Of the 122.8 billion dollars of foreign aid provided by Americans in 1975, 95.5 billion dollars, or 79 percent, came from private foundations, corporations, voluntary organizations, universities, religious organizations and individuals, although U.S. government aid is only 22 percent of the Gross National Income.† Therefore, one can see government aid, the kind Hardin mentions will ultimately deplete our resources, is fairly little in comparison to the rest of our nation’s finances. Furthermore, there are numerous other  countries in the developed world that hold the potential to distribute more than the United States alone. Realistically, the capacity of a wealthy lifeboat would be close to double the capacity Hardin presents; the boat would be, at the very least, closer to a small yacht than a meager lifeboat. Hardin’s lifeboat metaphor not only conceals facts, but also misleads about the effects of its proposals. Within Hardin’s scenario, the rich lifeboat can raise the ladder and choose not to let any more individuals on. In reality however, the problem does not necessarily go away merely because it is ignored. In the real world, there are armies and domestic dissidents who willingly sacrifice their lives and those of others to oppose policies they view as immoral. It is ignorant to assume all of the lifeboat passengers will agree with the decision that is made. Some individuals may attempt to pull the drowning on board, and hostility would be inevitable. Ultimately, Hardin’s lifeboat metaphor cannot accurately be applied to policy-making as it obscures more than it reveals. Throughout the article, Hardin bolsters his assertions by reference to a â€Å"commons†, or the tragedy of, in which he explains a system of private property which, if open to all, † †¦ the right of each to use it may not be matched by a corresponding responsibility to protect it† (3). He creates a picture to the reader using an example of herdsman with a pasture of a certain capacity. Hardin writes, † †¦ the considerate herdsman who refrains from overloading the commons suffers more than a selfish one who says his needs are greater †¦ It takes no less than everyone to ruin a system of voluntary restraint† (3). This statement is, like many of Hardin’s, entirely logical. Hardin explains that under a system of private property, the individual more easily recognizes responsibility (3). Under communal ownership however, Hardin argues the herdsman who may choose to fill the pasture with more sheep than it can hold for his own benefit wo uld promote his interest at the expense of the community as a whole. It is clear Hardin attempts to propose that the commons created by aid is worse than the original problem. This may indeed be true if the tragedy of the commons were truly a â€Å"tragedy† as Hardin claims, or if it were impenetrable, but that is hardly the case, and Hardin neglects to address this exact issue. Hardin  lacks sufficient, concrete evidence for this claim; creating a hypothetical situation is hardly grounds for a generalization of a large-scale issue. The incentive to leave out such facts can be seen later in the section, when Hardin quotes Alan Gregg, the vice-president of the Rockefeller foundation. Hardin writes, â€Å"He likened the growth and spread of humanity over the surface of the earth to the spread of cancer in the human body, remarking that ‘cancerous growths demand food; but, as far as I know, they have never been cured by getting it'† (5). To recognize any factual evidence that the Green Revolution has, in fact, resulted in increased food production would refute this quote, which provides the main support for Hardin’s argument. When researched, one can see why Hardin would neglect such information. In actuality, communal ownership has been tried in some countries with successful results. According to â€Å"Population and Food: A Critique of Lifeboat Ethics† by philosophers William Murdoch and Allen Oaten, instances of communal ownership have seen success. In Peru, the ownership of the commons has benefited a previously private-owned fishery, and China’s implication of communal agriculture has yet to see over-exploitation. If, however, a nation’s agriculture does not have success parallel to that of Peru and China, Hardin believes experience holds the key to unlocking poverty. In his section titled â€Å"Learning the Hard Way†, Hardin explains how developed nations currently budget and prepare for infrequent emergencies substantially better than impoverished nations. Furthermore, he argues:If each country is solely responsible for its own wellbeing, poorly managed ones will suffer. But they can learn from experience †¦ the weather varies from year to year, and periodic crop failures are certain †¦ should those nations that do manage to put something aside be forced to come to the rescue each time an emergency occurs among the poor nations? (4)Contrary to his typical pattern or argumentation, Hardin acknowledges the universal response of â€Å"kind-hearted† liberals, who find it difficult to grapple with the concept of blaming poverty-stricken individuals for the faults of their governments. In response, Hardin answers, â€Å"The concept of blame is simply not relevant here. The real question is, what are the operational consequence s of establishing a world food bank?† (4). This response exhibits  two of Hardin’s profound faults. By claiming that blame, in this instance, is an irrelevant point to discuss, Hardin neglects to address a very important issue. Why are the liberals wrong in arguing that fault of government should not influence action in providing aid? One may argue that faulty governments are a mere consequence of industrial deficiency, that can easily be fixed if aid is provided to nations who can then use financial assistance for education, resulting in educated political elections with educated individuals on the ballots. These political leaders may then be able to readily plan for emergencies. Neglecting to answer this rebuttal however, results in the presentation of an argument that seems ill-prepared and unreciprocated. Furthermore, Hardin contradicts himself a mere one sentence later, writing, â€Å"If it [a world food bank] is open to every country every time a need develops, slovenly rulers will not be motivated to save† (4). In saying this, Hardin clearly puts the responsibility of the nation’s food supply within the hands of the incompetent rulers, thereby insinuating the blame lies within the government, and ultimately eradicating any piece of information that could have been deemed support for a strong argument. In actuality, Hardin does not put much faith in the reform of such corrupt or incompetent rulers, despite calling that section â€Å"Learning the Hard Way†. Rather, Hardin believes that if the rich countries would simply refrain from giving assistance, the problem would take care of itself as, â€Å"population growth would be periodically checked by crop failures and famines. But if they can always draw on a world food bank in time of need, their populations can continue to grow unchecked, and so will their ‘need’ for aid† (5). When analyzed closely one can see Hardin neglects to address yet another prominent issue within his argument. How are underdeveloped nations expected to set aside food for the future when they do not possess enough for the current population? Denying aid would clearly cause death amongst many individuals, in saying this Hardin is correct. In making this statement however, Hardin incorrectly assumes the dependence on aid would diminish. Although crop failure would reduce population size, a stabilized population does not coincide with a more successful agricultural system. As a result, food would remain scarce, for even a drastic reduction would not guarantee enough food for the new population. It is naà ¯ve for Hardin to view this  solution as an end to dependency. Clearly the reduced population will suffer problems similar to the previous, food production will remain in deficit, need for aid will persist, and the crisis will continue to revolve in circles. Although many individuals propose the Green Revolution will decrease aid as well as increase food production in underdeveloped nations, Hardin neglects, once again, the importance of such a proposition in the next section of his article. To help alleviate the problems associated with crop failure, many scientists have created â€Å"miracle† rice and wheat that promise a larger harvest and greater resistance to damage. Within the section â€Å"Chinese Fish and Miracle Rice†, Hardin, once again, ignores a significant issue in an attempt to hide behind the weakness of his argument. Hardin writes, â€Å"Whether or not the Green Revolution can increase food production as much as its champions claim is a debatable put possibly irrelevant point† (5). Although there is room to debate the extent to which the Green Revolution has increased the crop yields of developing countries, as well as the costs of the loss of biodiversity and other environmental concerns, Hardin neglects to even mention them; they are dismissed in a single sentence. The true issue resides in that simple, blunt statement, for these topics are exactly the point. What is that finite number of people who can be sustained, and can we nudg e it further in the direction of survival? To ignore this essential statistic is to, once again, provide an argument that lacks support and coherence. One of Hardin’s last arguments relates to what he refers to as the largest issue with providing aid: the rapid population growth rates within impoverished nations. Hardin explains, â€Å"The people inside the lifeboats are doubling in numbers every 87 years; those swimming around us are doubling, on average, every 35 years, more than twice as fast as the rich† (2). Hardin then implements a real-world example in which he emphasizes the correlation between population increases and the depletion of resources: â€Å"Every one of the 15 million new lives added to India’s population puts an additional burden on the environment †¦ If rich countries make it possible, through foreign aid, for 600 million Indians to well to 1.2 billion †¦ will future  generations thank us for hastening the destruction of their environment?† (6). Hardin overlooks the fact that population growth rates are affected by many complex conditions besides food supply. There are vast arrays of socioeconomic conditions that can be identified that motivate parents to have fewer children. Thus, Hardin neglects to realize that population growth can be controlled effectively by intelligent intervention that sets up these appropriate conditions, rather than a reliance upon the statistics of natural population cycles. These conditions include the improved education and equality of women, literacy, sexual education, and distribution of contraceptives, all of which are attainable through the foreign aid that may be provided by developed nations, and according to Murdoch and Oaten, â€Å"aid may encourage necessary institutional and social reforms, making it easier for poor nations to use their own resources and initiative to help themselves.† Hardin neglects to refer to the statistics that illustrate the positive effects on population growth within developing nations that have received aid. Costa Rica, for example, has a relatively large population a nd a low GDP, but the birth rate has declined by fifteen percent since the implication of foreign aid has increased industrialization. Hardin’s article, â€Å"Lifeboat Ethics: The Case Against Helping the Poor†, holds more than twisted logic and misleading metaphors; it encompasses irony. Although Hardin consistently refers to his lifeboat metaphor, he, like the individuals in the boat, neglects to mention counter-arguments or deems certain information â€Å"irrelevant† in the attempt to save his own argument from sinking beneath the depths of deceit. Hardin was correct in stating that a particular boat may only hold its limited capacity, but this article needs to push off the inaccurate claims and leave room for those that are relevant if our world is to find a way to end poverty.

Literary Analysis on Death of a Salesman Essay

In Death of a Salesman by Arthur Miller, the conflict between a father and son shapes the overall meaning of the work and explains all of the adverse events that occur throughout. The sources of Willy and Biff’s conflicts, which include Biff’s delusional perception of the world as a result of ideas planted in him by his father, Biff’s discovery of his father’s affair, and Biff’s lack of business success all accumulate and result in the ultimate rivalry between the father and son. Altogether, these contribute greatly to the formation of the concept that personal dreams and desire to achieve success can often negatively interfere with personal relationships, and causing people to loose sight of what is important in our lives, as Willy and Biff exemplify. Throughout the play, there are flashbacks to Biff’s childhood as a successful athlete and motivated individual. Willy’s pride in his son’s accomplishments is apparent, as he constantly praises him saying, â€Å"Good work Biff!† (1561), yet Willy’s lack of acceptance of reality are as well. Frequently Bernard, a studious young boy, appears and reminds Willy of Biff’s unsatisfactory grades, yet Willy refuses to admit these downfalls and does not accept the reality of his son’s situation. Willy merely tells Bernard, â€Å"Don’t be a pest, Bernard! What an anemic!† (1560), and dismisses the negative statements made about Biff. Bernard constantly reappears almost as a symbol of Biff’s conscience, telling him to study or else he will not graduate. Willy does not help the situation and completely combats Bernard’s efforts by filling Biff’s head with lies and selling him on the idea of the American Dream as s omething that is easily achieved, by giving simple advice such as, â€Å"Be liked and you will never want† (1561). It is apparent that Willy weighs the importance of being well-liked and socially accepted more heavily than actual hard work and success, a negative reflection of his character. Willy preaches his philosophy that, â€Å"the man who makes an appearance in the business world, the man who creates personal interest, is the man who gets ahead† (1561). This is purely ironic due to the fact that Willy is the man who creates a personal interest in the business world with men of high status, but when all of his friends pass away he is left with nothing but a glorified past to remember. This false reality that Willy paints for Biff fosters the conflict between father and  son due to the fact that Biff fails as a result of the way he was raised. Biff follows his fathers ways and words, and by the time he takes his first job he has been raised to think that success and happiness will just come to him without excessive effort on his part. As any son would look up to and admire his father, Biff took his father’s advice and therefore makes no excessive efforts and put forth minimal work expecting to become successful merely because of his personality. This sense of entitlement is clearly diminished when Biff fails to keep a job and ends up at home. Willy never takes the time to teach Biff a good work ethic, good values, and strong morals, because Willy himself has not even established these within his own character. Therefore Biff steals, does not work hard, and finds it hard to make it in the real world. Willy himself does not know what is important in life, does not have morals, and does not value his family relationships, therefore he has no way of teaching Biff these vital tools for success and happiness. The resentment Willy feels because of Biff’s lack of success becomes the main conflict throughout the play ultimately reflects negatively upon Willy’s lack of ability to achieve the American dr eam himself, displaying Willy’s overall weak character. Biff’s discovery of his father’s affair serves as a main turning point for him as a character, a turning point that sends him downward into a life of struggle and lack of achievement. It is at this point that Biff loses respect for his father and begins to recognize the lie that he is living, thus making it a main source of conflict. Willy is in denial about his involvement with Biff’s failure in life, and when indirectly confronted by Bernard about the incident in Boston asking â€Å"What happened in Boston, Willy?† (1600), Willy becomes defensive, saying, â€Å"What are you trying to do, blame it on me? Don’t talk to me that way!† (1600). After being told about Biff’s reaction upon his return from Boston and the burning of his favorite University of Virginia shoes that symbolize Biff’s dreams and hopes for the future, Willy realizes the extent of impact that Biff’s discovery of the affair had. Willy’s lack of acc eptance of reality adversely affects his relationship with Biff because he never takes responsibility for his affair or even has the courage to admit it to Biff. As a result, when Biff discovers a woman in his father’s hotel room, he confronts his father, â€Å"You  fake! You phony little fake! You fake!† (1618) and all Willy can do is attempt to exercise his authority as a father which ultimately fails. Frequently throughout the play, Happy makes references to the man Biff used to be, asking him, â€Å"What happened, Biff? Where’s the old humor, the old confidence?† (1552). Learning about his father’s affair and seeing it firsthand that day in Boston was the turning point for Biff, the point where he grew up and realized that his father was a broken and defeated man, not the successful business man he portrayed himself as and used to be. As a result of this, Biff loses all respect for his father, and alternatively Willy begins to loathe Biff as well. Due to his discovery of the affair, Biff not only sees his father as a failed businessman, but a failed man. A man without money does not make him a bad man, but an adulterer who betrayed a woman who gave him everything cannot be forgiven in the eyes of a son. Throughout Willy’s continuous failures and defeats, his wife still remains supportive of him and loving, constantly reminding him of her affection for him. Despite this, Willy still yearns to have what he does not and thus pursues an extramarital relationship with â€Å"the other woman.† It is clear that Willy finds some kind of comfort and validation in this affair with a woman who makes him feel wanted, yet his wife does the same therefore it is clearly a matter of greed. â€Å"Willy’s sense of failure, his belief that he has no right to his wife, despite Linda’s love for him, is what motivates Willy’s deceptions, and those of his sons after him† (Bloom, Bloom’s Modern Critical Interpretations: Death of a Salesman). This event contributes to the overall meaning of the work as a symbol of the failure of the American Dream by Willy, not only in terms of personal success but also in terms of family relationship and his family’s success. Not only does Willy cheat on his wife, loathe his son, and struggle to keep a job, but he has let his values go and seems to have no moral compass of right and wrong. It shows that he has failed in the business aspect of his life, and also in his morals. Finally, Biff’s lack of success in the real world contributes largely to the conflict between him and his father. After having countless jobs over a period of several years, Biff returns home with loss of all hope of finding a steady job to support himself. Willy is disappointed by Biff’s lack of  ability to succeed, and, â€Å"It is to Biff, the returning son, to whom Willy relates most affectively.† (Hadomi, Rhythm Between Father and Son.) It is because Willy can see so much of himself in Biff and relates so heavily to him that these resentful feelings arise. Biff reflects his father’s failed ideals and expectations for himself, which are represented in Willy’s fantasies and flashbacks regarding Biff’s successful and glorious childhood, as well as expectations that Willy originally had for himself. Willy sees his failed life and career as a middle-aged man, and recognizes similar traits and qualities in Biff. Although he never expresses these, it is apparent that Willy largely sees himself in his son and thus takes out his anger for himself on Biff, resulting in constant fighting and conflict. The conflicted relationship between Willy and Biff exemplifies the theme of the work that in one’s pursuit of professional and material success, it is easy to become preoccupied with superficial aspects of life while simultaneously losing sight of what matters most. Willy’s preoccupation with his quest for material fulfillment ultimately results in a flawed relationship with his family, and ultimately with his son Biff when Willy sees him following in his footsteps. This conflict between father and son is what shapes the theme of the work and serves to highlight Miller’s purpose and the greater meaning of the play; that nothing is more important than family.

The Fashion Channel

The Fashion Channel The Fashion Channel is a TV network which features mainly fashion related content in its programs. It has a large subscriber base who are attracted by its content. Most of its viewers are women aged 35 to 54. The firm has operated without any customer segmentation, brand awareness or overall market strategies for a long time.Advertising We will write a custom case study sample on The Fashion Channel specifically for you for only $16.05 $11/page Learn More The firm seeks to change its market approach because it has realized that other TV networks are airing fashion programs targeting specific demographics. TFC intends to build a brand that will compete effectively in the market based on its reputation to capture more valuable customers. The vice president of marketing, Dana Wheeler is setting up strategies to help the firm become more competitive in the market. The firm has not been able to increase the revenue it earns from adverts because advertising firms feel programs aired have low ratings.The firm intends to push up sales revenues by focusing more on specific viewers to help it strengthen its position in the market. TFC wants to target specific customer segments in the market to make sure that its content reaches the right viewers. The firm needs to boost its ratings to attract more advertising revenue. The only way the firm can make advertisers interested in it is by airing content which appeals to young viewers who appreciate fashion. The firm also needs to maintain its spot on cable TV affiliates by ensuring viewers are more interested in programs it airs. Cable TV subscriptions offer the second largest revenue stream and it needs to improve the ratings of its programs to help it earn higher revenues. TFC is facing a lot of competition from mainstream TV networks which air a variety of content including fashion. Therefore, TFC needs to come up with content that targets premium viewers who have a strong appreciation for quality fashion. Lifetime and CNN, the two channels which threaten to overtake TFC in cable TV viewer ratings, have higher customer satisfaction scores compared to TFC. Low ratings have made the price cable TV consumers pay to subscribe to the channel to decrease. The firm needs to effect radical marketing strategies to help it increase the value of its service in the market. TFC needs to profile its customers to understand their behaviour and attitudes towards its services. This approach will help the firm to sustain strong relationships with its clients to make them feel valued.Advertising Looking for case study on business economics? Let's see if we can help you!

The firm needs to improve its market insight to make its marketing approaches more dynamic. The company has to face the reality that advertisers are interested in younger viewers bec ause of their willingness to try out bold trends in fashion. This has made the company’s marketing team to target a younger demographic of viewers aged 18 to 34. However, there are some serious issues the firm has to contend with by shifting its market strategy. This shift in market strategy have far reaching impacts on TFC’s long term operations. The 18 to 34 demographic is also targeted by many other networks and as such, the firm may not realise an increase in its advertising sales as it had projected. TFC needs to engage with its customers to understand their needs in order to serve them better. TFC ‘s strategies of focusing on many demographic segments, fashionistas and shoppers may offer it a wide range of benefits. However, the focus on multiple segments may deny the firm a chance to come up with niche content for its specific customers thereby limiting its market potential. If the firm opts for multiple segment programs, it will retain its loyal customers who do not want to see any radical changes in content aired. The focus on fashionstas will enable the firm to target more female viewers willing to try out new content that appeals to them. This approach may entice more advertisers to air commercials through TFC. However, TFC will incur a lot of costs when producing programs that target fashionistas. The focus on both fashionistas and shoppers will help TFC to increase its ratings because more viewers will be interested in its offerings. However, the firm will need to spend a lot of money to effect this change which shows that this alternative is highly risky. TFC needs to find a way to boost its ratings. It should allocate specific time slots for multiple segment programs to retain its loyal customers. TFC should introduce specific content targeting fashionistas and shoppers and assess the way viewers and advertisers react to it. The introduction of new content targeting these two segments should be done cautiously to ensure the f irm does not spend too much money which it cannot recover. The firm needs to increase premium content targeting fashionistas and shoppers only after getting positive reviews from customers.Advertising We will write a custom case study sample on The Fashion Channel specifically for you for only $16.05 $11/page Learn More This approach will help TFC increase the ratings of its products to make it more competitive in the market.

How to Exchange Data Over a Network Using Delphi

How to Exchange Data Over a Network Using Delphi Of all the components that  Delphi provides to support applications that exchange data over a network (internet, intranet, and local), two of the most common are  TServerSocket and TClientSocket, both of which are designed to support read and write functions over a TCP/IP connection. Winsock and Delphi Socket Components Windows Sockets (Winsock) provides an open interface for network programming under the Windows operating system. It offers a set of functions, data structures, and related parameters required to access the network services of any protocol stacks. Winsock acts as a link between network applications and underlying protocol stacks. Delphi socket components (wrappers for the Winsock) streamline the creation of applications that communicate with other systems using TCP/IP and related protocols. With sockets, you can read and write over connections to other machines without worrying about the details of the underlying networking software. The internet palette on the Delphi components toolbar hosts the TServerSocket and TClientSocket components as well as TcpClient, TcpServer,  and TUdpSocket. To start a socket connection using a socket component, you must specify a host and a port. In general, host specifies an alias for the IP address of the server system; port specifies the ID number that identifies the server socket connection. A Simple One-Way Program to Send Text To build a simple example using the socket components provided by Delphi, create two forms- one for the server and one for the client computer. The idea is to enable the clients to send some textual data to the server. To start, open Delphi twice, creating one project for the server application and one for the client. Server Side: On a form, insert one TServerSocket component and one TMemo component. In the OnCreate event for the form, add the next code: procedure TForm1.FormCreate(Sender: TObject);begin ServerSocket1.Port : 23; ServerSocket1.Active : True;end; The OnClose event should contain: procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);begin ServerSocket1.Active : false;end; Client Side: For the client application, add a TClientSocket, TEdit, and TButton component to a form. Insert the following code for the client: procedure TForm1.FormCreate(Sender: TObject);begin ClientSocket1.Port : 23; //local TCP/IP address of the server ClientSocket1.Host : 192.168.167.12; ClientSocket1.Active : true;end;procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);begin ClientSocket1.Active : false;end;procedure TForm1.Button1Click(Sender: TObject);beginif ClientSocket1.Active then ClientSocket1.Socket.SendText(Edit1.Text);end; The code pretty much describes itself: when a client clicks a button, the text specified inside the Edit1 component will be sent to the server with specified port and host address. Back to the Server: The final touch in this sample is to provide a function for the server to see the data the client is sending. The event we are interested in is OnClientRead- it occurs when the server socket should read information from a client socket. procedure TForm1.ServerSocket1ClientRead(Sender: TObject; Socket: TCustomWinSocket);begin Memo1.Lines.Add(Socket.ReceiveText);end; When  more than one client sends data to the server, youll need a little more to code: procedure TForm1.ServerSocket1ClientRead(Sender: TObject; Socket: TCustomWinSocket);var i:integer; sRec : string;beginfor i : 0 to ServerSocket1.Socket.ActiveConnections-1 dobeginwith ServerSocket1.Socket.Connections[i] dobegin sRec : ReceiveText; if sRecr thenbegin Memo1.Lines.Add(RemoteAddress sends :) ; Memo1.Lines.Add(sRecr); end; end; end;end; When the server reads information from a client socket, it adds that text to the Memo component; both the text and the client RemoteAddress are added, so youll know which client sent the information. In more sophisticated implementations, aliases for known IP addresses can serve as a substitute. For a more complex project that uses these components, explore the Delphi Demos Internet Chat project. Its a simple network chat application that uses one form (project) for both the server and the client.

MPM DB3 - Essay Example A project manager should be a team builder with the ability of facilitating the team to work in the right conditions. The right team is very important to enhance the meeting of expectations. The project manager must be decisive, considering the many decisions to be made everyday. He should have influential and have good negotiation skills, which will enable him in solving disputes that may arise while at work (Barry, 2010). A good project manager should also be a good planner, able to consider work schedules, manage resources, and meet deadlines. While all the qualities of a project manager are important to facilitate the success and effectiveness of this project, two aspects I think a very essential are visionary leadership and communication. This is because a project manager who has a vision will have knowledge in placing the right people in the right places so that the projects goals are achieved. He will also know how to sell the vision to the team, make them appreciate their roles in propagating the vision regardless of their position in the team, and even develop their own visions pertaining what is expected of them in achieving it. The visionary leader encourages and motivates, acts as a mentor and facilitates productivity, and these are crucial to success of any project. Communication will also be a very important aspect for the success of the project. Proper flow of communication initiated by the project manager to the team and among the team members is important if team work is to be enhanced and production is to be maximized. Investing in current technology is important as it facilitates communication regardless of location. The project manager should be able to ensure that there are proper mechanisms to control the flow of information and keep track of feed back (Syntel, Inc., 2012). This will facilitate agreement on all aspects across the board. It is important that for everything that is
