Nutrasweet in China Essay

To come up with a decision to the whether enter the Greater China Market or not we decided to approach the case with a SWOT analysis. Strengths NutraSweet is an artificial sweetener that is one of the most recognized brand names in the United States and in the world. NutraSweet’s earnings per share is $ 6. 36 and with huge capitalization and investments in diverse products. Stacey has the approved budget of $ 500,000 to market NutraSweet in China. NutraSweet has the flexibility on how to position their product in terms of functionality, or either as sugar substitute or health product for diabetics. Weaknesses The research conducted towards the Chinese consumers may not truly reflect the real sentiments of the consumers towards NutraSweet. NutraSweet has not decided on building its own distribution system and may rely on foreign agents for distribution. NutraSweet is more expensive than ordinary white sugar. Opportunities China is a big market and can provide higher profitability to the company. China is the second or eighth largest economy in the world; depending on how it was gauged. There is a perceived consumers’ infatuation with Western brands. Chinese maintain healthful lifestyle so the potential for NutraSweet to launch their product in China is strong. Threats Sugar is a common household purchase as a sweetener and has been part of Chinese households for decades. Culture dictates that there might be difficulty in replacing traditional use of sugar with NutraSweet. The Chinese market is so diverse and it is difficult to come up with a general characteristic to define them. Artificial sweeteners are known by history of skepticism for saccharin and potential health hazards. There is difficulty in attracting and retaining local employees and as such, NutraSweet is having doubts in investing into training their marketing and sales personnel for fear that the employees would not stay long in the company. There are only very few foreign agents that operate in China. Sugar use and consumption levels differed among 3 key markets –Shanghai, Guangzhou, and Beijing. Arthur Andersen survey in China showed that most joint ventures from food and drink were not profitable. Most MNCs in China are unprofitable despite substantial growth. Majority of the Chinese are considered â€Å"flat-bellied† and don’t see the need for a diet regimen. The Chinese culture also dictates that they are not that concerned with their teeth, hence they don’t have that fear of tooth decay. The company should enter the Greater China market as a niche product for consumers with a medical need. The company cannot delay its entry in the China market, especially with factors such as an average of 10% economic growth, a quickly emerging middle class, and a high possibility in consumers’ increase purchasing power. Postponement of entry may mean higher costs in the future and although the company will not immediately profit from the venture, research showed that companies who entered the market 5 to 10 years ago were doing best. The knowledge gained from market entry will allow NutraSweet to sharpen its future strategies. Pros The successful experience in establishing medical awareness in Hong Kong may be applied to the Greater China Market. Entering the Greater China market through the three key cities will provide a better knowledge of the overall Chinese market. A natural market consisting of diabetics and obese customers already exist. Hospital stores and drug dispensaries do not have the bargaining strength that retailers have. Product information campaigns will be facilitated by health professionals who will easily understand and appreciate the product’s benefits. Promotion to medical professionals through associations will not need as much cost as a nationwide mass-market campaign. A $ 2,010,526. 31 in breakeven sales seems very feasible in the Chinese market. Cons The Chinese tend to be slim and had historically not been preoccupied by tooth decay. ? SHORT-TERM The Chinese consumers’ attraction to brand names, especially the number 1 in any category gives NutraSweet an opportunity to establish itself as a first mover in the medical aid products under a new category of sweeteners. The company will launch a product information campaign for medical professionals and will also tap their associations. Associations of diabetics and obese consumers will also be tapped. The company will focus on relationship building with the medical industry. Since poor dental health is a problem in China, the company may also create an awareness drive on the ill effects of sugar on the teeth to lay the foundation of need awareness. The product will be packaged in sachet form with global brand and American image prominent on the sachet to appeal to the consumers’ preference for American brands. The company will capitalize on the convenience of bringing the sachets anywhere with you. The medical industry will be given free samples of the product. The doctors will be taught to promote daily use of the product, with sweetening of milk and coffee or hot drinks as one of the more common purposes. Consumers will be taught to use the product in cooking through the provision of free recipe booklets and cooking demonstration classes. The product will be distributed in the three key cities of Greater China, namely, Guangzhou, Shanghai, and Beijing, where the medical industry is more developed compared with the other cities. The company will create its own distribution structure. The product will use the distribution channels of hospital stores and drug dispensaries. Since the focus is on niche marketing, the product will still be sourced from the U. S. plant. LONG-TERM The long-term goal will be to mass market the product in Hong Kong and Taiwan, and use the learning’s from those markets to penetrate the market Greater China. Establishing distribution networks in the two countries will be easier, given the favorable business environments. In Hong Kong and Taiwan, the product will be repositioned as a healthy family lifestyle food, targeting the affluent, health and weight conscious consumers. Aggressive promotion will be pursued, such as print and media ads, and the employment of product endorsers, and store promotions. Consumer awareness and education will be the focus of the campaigns.

A Hard Days Night

Music is one of the Great Britain's most marvelous contributions to the world, despite the tendency of musical movements over the last four decades to spawn cultures that appear to morally damage the social norms, especially on the youth. Much of the phenomenon can be attributed to the advent and development of television as a medium of communication, for television has vastly catapulted the career of popular musicians to a whole new level. In a similar magnitude, cinema has also projected negative implications on how common people treat celebrities. Together with television, cinema has dehumanized celebrities in such a way that society and culture, particularly in the west, have eventually nurtured television viewers with mindless conformity to the media as well as a fully developed system of glorifying celebrities and their radical behavior. The tremors of broadcast media and cinema have produced the concept of superficiality and prejudice as a basis for popularity. It is quite evident on how movie stars, musicians, athletes, and commercial models are treated in restaurants and other public places. The motion picture A Hard Day's Night, for instance, exemplifies and tackles the backlash of the demeaning nature of popularity as felt by celebrities in a personal level since they themselves feel the luxury of a normal life gradually departing from them. The context of the film is inclined on the idea that the visual elements provided by cinema and television create a following of a particular artist or group of artists based on appearance and not on talent. In analysis of the growing problem, Kevin Donnelly's British Film Music and Musicals emphasizes the phenomenon of how A Hard Day's Night became the antidote to the venom brought about by cinema and television's visuals in such a way that the focus is more on The Beatles' music as the storyteller instead of the plot or the cast themselves (Donnelly, 2007). Contrary to other films involving music artists such as the legendary Elvis Presley who has been the guinea pig of film makers who did nothing but to exploit his popularity in film. Donnelly writes that the film virtually connects viewers to the band through the musical score which goes hand in hand with the situation and emotions that the film's scenes raise (2007). The songs suggest how the Beatles scorn about the fringe benefits of popularity while dealing with the punishing nature of their duties such as recording and touring. The virtual contact also happens as the motion picture shares the band's brutal torments of having a celebrity life while sacrificing their personal goals and interests. The visual technologies of cinema and film indeed contribute to the actuality that such mediums of communication make deities out of celebrities. In this sense, A Hard Day's Night represents and reflects the the star-making machinery around The Beatles in such a way that it documents of The Beatles' misadventures in the United States during the peak of their career. The band's grasp with commercial success were represented through encounters of pursuit by law enforcers and a horde of fans as well as their appearances on press conferences, endeavors with their agents, and hotel life (Balio, 1987). Therefore, Such circumstances are quite similar to the cases of modern celebrities being sighted and chased on public places or being arrested for driving fast and under the influence of psychoactive substances. A Hard Day's Night, meanwhile celebrates the band's stardom in a different manner, by highlighting the band's versatility as musicians since part of the film captures the band's latest compositions at the time, being played during practice sessions, live performances, and informal set-ups (Balio, 1987). The film's distinct approach to the topic subjects the tendency of visuals such as film and television as career boosters in such a way that the showcase of the band's talent through live performances are shown, unlike traditional musician oriented films which make use of the artist's recorded material. In a corresponding approach, A Hard Day's Night together with the film and television industry serve as a mockery of the star-making machinery around The Beatles as well as other celebrities and popular personalities, primarily because music is an art form which stimulates appreciation through hearing. As such, the dedicated medium of communication for expressing the art of music and recording artists is supposed to be the radio, not television, film, and definitely not print. The motion picture also insults the The Beatles as artists by humorously tackling the problem of pop fame, which the band members experience, through a medium that caused such a plague in the first place (Glynn, 2005). In addition, the polluting nature of television and cinema has once again made its presence felt as the visuals have proven to be useful aids in exploiting artists and promoting the developed system of idolizing celebrities, which is in this case happens to be The Beatles. Furthermore, the visuals provided by television and film entombs true musical talent by taking away the recording artists' musical credibility (Frith, 2002). Simon Frith (2002) however implies that rock is to be understood as a television product. The key elements and features of television and film, for Frith, have configured the manner of how the audience perceive music and musicians. Simon Frith writes that television has become largely responsible in the field of star-making for the reason that television with its emphasis on close-ups of the performer and musical virtuosity, particular types of staging and spectacle has added flavor to musicians as celebrated public figures (2002). Frith also adds that the emergeance of music networks such as Music Television together with several music related television programs such as Top of the Pops have also aided artists in terms of promotion which affects components of stardom such as record sales and chart ratings (Frith, 2002). The advent of technology has indeed influenced the the norms and standards for treatment of celebrities. Visuals, in an unimaginable, have added spice to musicians as attractions to the public eye, with it, the innovation of promotion for recording artists have revolutionized. Regardless if the changes brought about by the television and motion picture industry to the public status of career musicians have positive or negative undertones, the bottom-line still goes down to a particular point, change. A change that has been felt almost half a century after it has long been innovated and practiced.

Assisted Suicide Research Paper Example | Topics and Well Written Essays - 2750 words

Assisted Suicide - Research Paper Example The minutes pass like hours and you’ve been in this condition for three years. Relatives and friends occasionally come by but the visit is brief and filled with only sadness. What are you thinking as the minutes, days, months and years pass? Most, it would seem, would be praying to die wondering why anyone would be allowed to suffer physical and psychological pain endlessly. It is the worst type of torment, one without control or end. If you can speak, no health care worker will hasten death. If you cannot speak you cannot even express your wishes. If you were the family dog, society would have fully condoned that the â€Å"humane† option was taken and you were â€Å"put to sleep.† Laws that prohibit euthanasia are government mandated torture. The option of euthanasia, or doctor assisted suicide (DAS), strengthens the important doctor/patient relationship, respects an individuals dignity and right of personal autonomy in addition to reducing the suffering of pati ent, their families and the medical costs to both. Euthanasia is the contraction of Greek words meaning â€Å"good death† but too many people die gripped in pain, guilt and humiliation, a bad way to die. It’s shameful for a society to somehow justify the prohibition and criminalization of DAS. Statistics The General Population Those who oppose the concept of legal DAS usually do so based on religious grounds, believing that only God has the right to give and take life. Others claim that because people don’t decide how and when they are born they should not decide how and when they die. They also caution that legalizing euthanasia is a â€Å"slippery slope† and could result in an abuse of authority, that people could be euthanized when they don’t really want to die. Opponents to euthanasia are in the minority however, and support for a compassionate death is growing. In 2002, a Harris poll found that sixty-five percent supported legalization of DAS while sixty-one percent supported implementing a variation of Oregon’s Dignity Act enacted in their own state. The Act allows terminally-ill patients to die by self-administrating lethal drugs that were prescribed by a doctor for that specific reason. A series of studies involving patients with a terminal illness revealed at least two-thirds would like to have the option of a DAS. Surveys taken in California during 2005 and 2006 found seven in ten favored the idea that â€Å"incurably ill patients have the right to ask for and get life-ending medication.† (Fieser, 2011) Though it didn’t pass, a DAS bill introduced in 2005 to the California State Legislature gained passionate support. The Medical Community Support for legalized euthanasia is also found among those of strong religious faith though not to the degree as the general public and medical community. A 2005 national survey of doctors found fifty-seven percent consider DAS ethical. A Journal of the America n Medical Association survey in 2001 found a clear majority support the Dignity Act. Also in 2001, the Journal of General Internal Medicine found that forty-five percent of doctors thought DAS should be lawful and just thirty-four percent opposed. Mental health professionals realize that terminally ill patients can choose to die while mentally competent. A rational person can choose death as an alternative. Many medical groups have determined to adopt a â€Å"studied neutrality† stance on the subject of DAS, realizing not all within the medical field agree. (Fieser, 2011)

Composer report Essay Example | Topics and Well Written Essays - 250 words - 1

Composer report - Essay Example analysis because of his multifaceted performance since he was not only outstanding composer, but also talented conductor, poet-playwright, publicist and theorist of musical theatre. Almost alone, Wagner created an entire trend such as musical drama. The most distinguished thing that a lot of his works are characterized with is a prominent role of mystical symbolism, which always inspired composer and fascinated intellectual audience. Wagner’s contribution to the world culture is defined, first of all, with operatic reform, which led to the dominant implementation of recitative style, popularization of symphonic operas with the help of leitmotifs and refusal from tradition operatic forms like aria or ensemble. The centre of Wagner’s performance is a synthesis of arts representing combination of music, poetry and theatrical play that are able to create overall picture of events. The music of Wagner is saturated with painful search for happiness, intention for heroic deeds and recurrent presence of deception, violence and treachery that often darken the real life. The composer’s style is characterized with excessive tragedy and actualization of myths. While listening to Wagner’s music, it is possible to feel grandeur, power, potency, audacity and determination of the creator. Wagner is miscellaneous in his representations. Hence, â€Å"Spring Waltz† is airy, light, melodic, playful and exciting set of notes, while â€Å"Die Walkure† attracts with its loudness, anxiety and expressiveness that merely cause heartache. This is typical for Wagner to be ostentatious and even scandalous right in a focus of public attention. Such nature of composer can be easily tracked and reflected in his music that presents a great surge of emotions for the

The Four-Firm Concentration Ratio Essay Example | Topics and Well Written Essays - 750 words

The Four-Firm Concentration Ratio - Essay Example Eventually, the excess demand would be met and the price would again gain equilibrium. The long run plans in this situation would be undertaken to maintain minimum long-range average cost. Increasing production in the short run may increase marginal cost. Long range plans would again bring these under control. The relatively low concentration level dictates that firms make plans and take actions based on the market, as no one of them can become a price maker. The market will set the price. In the case where there are 20 firms with a four-firm CR of 80%, the firms would act differently. With fewer firms controlling a greater market share, they may be slower to react to the increase in demand. They may maximize profits by operating inefficiently. This may involve collusion either through agreements (price fixing) or a de facto situation where no producer wants to upset the pricing (Gilligan 2002). Prices would stay high until one of the firms, or an entrant, took action to fill the increased demand. Concentration in an industry or sector can be, according to Gilligan (2002), "... a reward for being successful". Firms that produce the best products at the lowest cost will naturally come to dominate a market. Barriers to entry can also result in a high concentration ratio when new entrants are barred. ... A firm that has a dominant position in a market may be a price leader. Since they control the only supply, they can set the price. This will usually result in operating inefficiently. They will produce fewer units at a higher cost and much greater price. This will maximize their profits. In a contestable market, the dominant firm will have to remain competitive even though they may have no competitors. If there are no barriers to entry, and the cost of entry is low, the dominant firm must sell at an equilibrium price to keep new entrants from competing. If they raise the price, new firms will enter the market and sell at a lower price. This will force the price back down and the new entrant will then exit the market if there are no barriers to exit. The Purpose of Anti-Trust Legislation Steve Ballmer, CEO of Microsoft, contends that, "We do not have a monopoly. We have market share" (cited in BrainyQuote 2007). In fact, the case against Microsoft was never about being a monopoly. It was about how they became and maintained a monopoly status. The original intent of anti-trust legislation, and indeed its only purpose, "is to promote economic efficiency" (Scott et al. 1998). Promoting economic efficiency dictates that the market must be a place of free competition. Collusion, coercion, and manipulation that places a competitor at a disadvantage reduces market efficiency. From the years 1990 - present, Microsoft has engaged in numerous activities whose sole purpose was to limit competition and place obstacles in the path of competitors (U.S. v. Microsoft 2002). Monopolies are not always illegal and big is not always bad. It is the collusion with vendors and suppliers in an effort to make it

Good Night and Good Luck Movie Review Example | Topics and Well Written Essays - 750 words

Good Night and Good Luck - Movie Review Example As with all entities which do not posses power, new media was also controlled and influenced by different spheres of power. This was the period when the cold war was at its initial stages. The government was using all channels of communication it could to gather support for its anti communism agenda. This agenda allowed American governments to allocate billions of dollars to defense contracts and war spending. This cold war mass hysteria was being sponsored by many different spheres of power. The propaganda was so strong that being a communist became a crime. The government used all resources that it could muster to spread this hatred towards communism. The television was in that time period a new phenomenon. The attraction of television to masses was tremendous and very reliable. People took it as a new and reliable source because there was a lack of understanding about it. The government tried to use this as a propaganda tool for their anti communist agenda. One senator of Wisconsin took this as a personal crusade and went to all means necessary to propagate his anti communist agenda. There were however some men even than who understood the real place of television journalism. Senator Joseph McCarthy of Wisconsin faced severe criticism and retaliation from the CBS new team. These people were willing to fight to any means necessary to ensure that trust prevailed at all cost. The main man in this fight for the freedom and independence of new media was Edward R. Murrow. His team included co-producer Fred Friendly and reporter Joseph Wershba. The main revenues as is understood came from the commercial. At that time there was no concept of paper per view. Therefore television channels were completely dependent on TV commercials to fund their operations. Edward R. Murrow and his team had to face a huge pressure from many different corporate sponsors as well. When Gore Vidal said that television was the first time in world

Business strstegy - Essay Example In such changing environment, it is must for the organizations and the institutions to have enough flexibility and adaptability within the policies and procedures of such bodies so that the changing terms can be easily inculcated. Such flexibility and adaptability has become the key for the sustainable growth and development of the organizations and institutions. Forestry Commission was established in England in the year of 1919 through the passing of the Forestry Act. The prime reason of the establishment of such Commission was aimed at supplying the much required timbers that were in scarcity in those years because of the industrial revolution and the First World War. The government of England speculated another war in the near future and thought it was necessary to have proper supply of timber. The secondary reason of the formation of such Commission was to ensure employment in the rural economy because of the changed political equations and also to provide employment to the soldiers those have just returned from the war. Therefore, to serve so many of the objectives the Forestry Commission was formulated which till recently was under the control of the ex-army men and more importantly followed the organizational structure similar to that of the military. The structure was essentially a top-down one with much emphasis on the features like chain of command and order from the top. With the changing times, the role of the Forestry Commission also experienced paradigm shift. The department of the government that came in to existence for the purpose of timber production and rural employment was pressed by the government in the 70s and 80s to inculcate organizational efficiency like other departments of the government. The Forestry Commission also had certain internal conflicts. There was a clear difference among the organizational hierarchy resulting in ‘them’ and ‘us’. Those who were the field

Managing across borders Essay Example | Topics and Well Written Essays - 1250 words

Managing across borders - Essay Example Kelly and her family are clearly being affected by the cross-cultural differences between themselves and the Japanese people. The family of Kelly is having a difficulty to adapt to the new environment thus, finding it hard to live in Japan. In addition, Kelly and her family have very little information concerning the area and thus, they keep on doing things in the American style thus, they end up having a hard time to survive with the Japanese. Kelly experiences a hard time at work due to the fact that she is a female while the Japanese are used to being led by males. Thus, gender discrimination is also a major issue in Kelly’s case. Clashes in culture customs Kelly’s case presents to us a number of clashes between the American culture and the Japanese culture. This is because; the Japanese culture is very different from the American culture and the two are characterized by different ways of handling issues. Kelly has worked in London and Boston as a female and yet, the re was no one who thought it being funny or weird for a woman to be a boss. However, in Japan she has a hard time since; the Japanese employees expected that the boss would be a man as opposed to a woman. Thus, there exists a clash in cultures since, according to the Japanese culture, it is men that should lead the women while, according to the American culture, women can also lead the men. According to the cross-cultural management theory formulated by Fons Trompenaars, cross cultural differences at work between employees can be solved can by communication (Van Mol, 2005, 31). Kelly experiences difficulties at work due to lack of fluent communication between her and the Japanese people. Therefore, she has to seek advice from Peter, her assistant, each time she experiences difficulties. However, had there been fluent and perfect communication between Kelly and the Japanese employees, the former would be aware of what to do each time when working with them. In addition, the Japanese employees are also finding it difficult to adapt to the fact that their new boss is a female. Hence, they end up having trouble in doing their work. According to the cross-cultural management theory, cross-cultural differences can also be eliminated through accepting and respecting them. Kelly’s husband Joe is experiencing a hard time in Japan because he has not yet accepted the fact that Japan is different from America. For instance, he finds it hard to adapt to the Japanese meals and keeps on complaining to her wife. Joe’s expectations were that; they would have a new experience in Japan, full of new experiences. Contrary to his expectations, Japan has turned out to be a very expensive country to live in, with a lot of difficulty in finding a new job. The family also had expectations that the expensive apartment would be big and spacious to fit all their possessions. Contrary to their expectations, the house has turned out to be very small and tiny, with no back yard for the children to play (Sanger, Intercultural Press & Bull Worldwide Information Systems 1990). Kelly’s stage of culture shock The first stage of culture shock is usually Jet-Lag and Wonder (Tabak,  2007, 1). This stage is also referred to as the honeymoon phase, where an individual gets excited by the new experiences about food, culture and language (Munan, 2008, 33). Kelly’s family went through this stage at first when they arrived in Tokyo tired but very excited. At this time, all they could see was the beauty of Japan in spring and were just making plans to spend their weekend sightseeing and travelling around. The second stage of culture shock is frustration (Tabak,  2007, 1). This is a period during which a person gets to experience the hardship of living in a new country (Ellis,  2001, 34). The individual finds it difficult to understand the new language used and gets laughed at when he or she makes mistakes while communicating. The usual response at th is

The Comedy Genre Essay Example | Topics and Well Written Essays - 1250 words

The Comedy Genre - Essay Example The first commercially successful romantic comedy to posit an alternative notion to this underlying concept did not get made until the 1970s. Woody Allen's Annie Hall is dictated by the external social forces of that decade just as much as the screwball comedies were dictated by the economic and social upheaval of the Depression. Annie Hall stakes out a claim for being the first romantic comedy to display the multiple neuroses inherent in a realistic sexual relationship. It is the neuroses of Alvy and Annie that present the obstruction that leads to what becomes the film's most unconventional upending of genre of romantic comedy: the two do not end up together. Until Allen's film the very concept that the romantic leads would not end up together was the definition of a romantic tragedy film. In another Woody Allen film, Crimes and Misdemeanors, Lester, the successful TV producer, manages to boil down the entire essence of comedy into one simple equation: "If it bends, it's funny. If it breaks, it's not funny." Lester's unctuous delivery of his theory of comedy undermines the serious contemplation of its message, but Lester is essentially simplifying one of the elements of the far more philosophically expansive suppositions about what makes a person laugh forwarded by Henri Bergson, who writes of comedy that "Indifference is its natural environment, for laughter has no greater foe than emotion" (Bergson 4). The implication is that comedy must by its very nature be distanced from the natural emotions involved in an otherwise realistic situation. Annie Hall establishes distance from the pain experienced by Alvy and Annie as their relationship crumbles by subverting the mechanics of the romantic comedy genre. The traditional arc of a romantic comedy since the screwball era is one that begins with an antagonistic relationship between the man and woman that evolves into mutual attraction before finally ending with consummation. Annie Hall reverses this trajectory by presenting Alvy and Annie as immediately attracted to one another and ending with their romantic parting. The distancing from the undercurrent of tragedy within the story arc of Annie Hall is also accomplished through its insistence on breaking down another convention of the romantic comedy. More so than any other type of comedy, the pre-Annie Hall romantic comedy eschews any intrusion into its carefully constructed sense of reality. Annie Hall, by contrasts, blasts through the fourth wall and at times also becomes an exercise in surrealism: the scene with the subti tles showing what Alvy and Annie are really thinking as they engage in phony small talk; the scene with at the movie theater at which Alvy magically produces Marshall McLuhan. These devices distance the audience from the heightened emotions at stake; ultimately, it becomes clear this relationship is not just going to bend, but break. Annie Hall becomes the first American romantic comedy to find the comic potential not in two people falling in love, but in what happens after the consummation that climaxed the earlier examples of the genre. Annie Hall may have given rise to a new sub-sub-genre of comedy, the anti-romantic comedy, but external social forces served to collide with

Compare how Willy Russell Essay Example for Free

Compare how Willy Russell Essay Compare how Willy Russell portrays the two brothers in Blood Brothers. Account for the different reactions the audience have to the two characters throughout the play. Willy Russell successful playwright Blood Brothers conjures up many debateable topics including the intriguing separation of twin brothers Mickey and Eddie. During my essay I shall indulge into the social differences and similarities occurring between the twin brothers, whilst giving personal responses of my own and explaining the effects materializing on the audience and if it is what Russell hoped for. I shall give thought provoking evidence to back up my opinions and create emotional differing acknowledgements to enhance my essay. The theme constantly running through the play is that of a social difference and a difference in class. The title Blood Brothers has several denotations with Blood meaning possible violence or a blood relation whereas Brothers could mean a close/good relationship. The opening line Have you ever heard the story of the Johnston brothers? makes the audience inquisitive from the start, and sets the scene for the story. From the first mention of the brothers in Act 1 Scene 5, the audience can notice Edward is instantly shown to be more socially superior to Mickey having been chosen by Mrs Lyons to be the baby to have the life of luxury and live with her. She pressurised Mrs Johnston to say At the birth of my twins I shall give one of the children to Jennifer J. Lyons. Russell is trying to cause an early rift amongst the brothers and profound that society treats people in many different ways and can pave the way for peoples lifespan. The audience feel generally excited towards this turning point in the play and would love to know how the rest of the play and the brothers lifes pan out. I feel a certain sorrow for Mrs Johnston having been threatened by Mrs Lyons, to secure the rights of Edward. In Act 1 Scene 8, Mrs Lyons says They say that if either twin learns he was one of a pair they shall both die immediately. Despite a great sadness for Mrs Johnston, I also feel a magnitude of happiness and hope for the great life Edward shall have before him. Once the brothers meet the comparison between the two experiences another social difference, as in terms of manner the brothers speak within a whole different complex. Poor manners and a broad liverpudlian accent are reminiscent of something Mickey would say. In Act 2 Scene2 Mickey says Im not playing now because I am pissed off. Whereas the well spoken Eddie would say Fantastic, I shall look it up in the dictionary. This particular difference occurs due to the far from similar worlds the brothers have been brought up in; this difference would make the audience think the brothers had no relation or link whatsoever. The audience also feel sorrow for Mickey knowing he has not had the same chances as his brother but I can also presumably see humour as the brothers diverse childhoods lead them to say contrastingly opposite things. Again in Act 2 Scene2 the level of knowledge between the two brothers is also experiencing a huge difference, exaggerating that the upper class are more intelligent than the lower class. Again Russell is trying to convince the audience that Eddie is benefitting from his greater advanced sociality. Eddie says Dont you know what a dictionary is? Mickey responds Course I do. Its a thingy isnt it? Eddies question may insult the intelligence of Mickey but again the different upbringings result in a difference of knowledge. The audience and I feel pitiful for the poor Eddie who hasnt had the same chances as his brother yet I can see a humorous side as Russell again exaggerates how less intelligent lower class people are. Mrs Lyons tells her son not to play down where Mickey lives. Two possible reasons for this could explain Mrs Lyons concerns. The first reason could be that Mrs Lyons doesnt want Eddie to play with children with such a gulf in class and mix with the wrong kind. The second reason could be how Mrs Lyons doesnt want Eddie to meet Mickey and unravel the truth about their brotherhood. Mrs Lyons says Ive told you never to go where that boy lives. I believe the audience vent their first bit of anger, aimed at Mrs Lyons as she is hiding the inevitable truth from Eddie and the audience probably believe the brothers deserve to know the truth. But telling the truth could ruin Mrs Lyons chance of parenthood. Mickey ventures into an adventurous life and Eddie very much wants to follow in his steps. Many quotes prove this, like when in Act 2 Scene3 Mickey says Hiya Eddie. Look, Ive got our Sammys catapult. You coming out eh? Eddie replies Isnt Mickey fantastic, Mum? This shows the first of many similarities between Eddie and Mickey and despite different lifes, there is still a likability factor between the two and they enjoy playing and being mischievous. This bond between the brothers pleases the audience who want the boys to happily reveal the secret, being kept from them. Mickey persuades Eddie into light hearted behaviour (peer pressure). Eddie, despite reluctant still enrols in this misbehaviour, showing a side similar to his brother.

Eye Tracking in Usability Evaluation

Eye Tracking in Usability Evaluation   In this literature review I have talked about experiments conducted on usability of various interfaces and designs using eye-tracking. The authors of the papers focus on various types of eye movements for usability evaluations like saccades, pupil dilation, fixation, scanpaths etc. Based on these measurements the try to infer the point/area of interest of the users, point on entry, the cognitive load etc. about the user. These conclusions help in understanding the mindset of the users which can be generalised to a larger population within the proximity of time and space and help in making recommendations for better design of the interface. Benefits of eye tracking: Eye tracking has many benefits. Using eye tracking methods for usability evaluation one can track how the users interact with a given interface or environment. They help in measuring the effectiveness of a visual element on the interface. The measurements recorded can give an insight into the users mind while making a decision regrading searching or navigating an interface. This can be done by measuring what users are interested in, what they are ignoring and what is distracting them from their current tasks. They help in figuring out the Area of Interest which I a randomly shaped box that may contain some information or object or potential interest to the user. The quantitative data collected through eye tracking gives a visuals representation usually in the form of heatmaps(hotspots) which help in better understanding the results. Eye tracking equipments used now-a-days like Tobii and SMI are easy to set-up, calibrate and handle. They are unobtrusive and p rovided accurate real-time feedback. The fast passed usability testing of the software development industry, test conducted using eye tracking can of valuable and useful input providing benefits what will help the users. Eye Tracking in Usability Evalusation: A practitioners Guide [1] This paper is a general guideline on the use of eye tracking used for usability evaluation. The author talks about the specialists who conduct the study, the metrics used with the testing, the protocol followed to conduct a test. They also talk about when eye tracking can come in handy as compared to the normal usability test which usually include heuristic evaluation, cognitive walkthrough, checklist, remoter-usability testing, click-tracking etc. The authors talk about the different types of eye movements that are measured like saccades, fixation, pupil dilation, scanpaths etc. These movements provide a log of the visual attention of a user on the interface. It is also interesting to know that the eye tracking gadgets only track the movement of one eye, usually the dominant eye of the beholder. Saccades: rapid eye movements. Fixation: A linger at a point for more than 300ms. Scanpath: established by the sequence of saccades and fixations. Most of the studies conducted analyzed the fixation pattern. Which can be realized through heatmaps. Red indicates the highest level of fixation followed by green yellow. The areas which are not colored drew no attention. F-Shaped Pattern for reading web content[4] The author says that a eye tracking study was conducted on 232 users on their reading behaviour on webpages. They found a governing F shaped pattern which was undeviating among most of the users. The participants of the experiment were fond to first adhere a long horizontal gaze across the screen, followed by a short horizontal gaze on the area below and finally giving a quick vertical scan of the content of the webpage. Occasionally there were a few cases of an E and an L shaped pattern but mostly F was dominant with variation in the placement of the horizontal bars. These patterns suggest hat usres dont read the text on a website line by line. They like to give a scan to see if any of the content available if of interest or not. Such reading patterns suggest that first paragraph should contain important and catchy information. While scanning vertically users generally users generally read the first two words of the text. Visual Hierarchy and Viewing Behaviour: An eye tracking study[2] The authors of this paper aim to suggest effective improvements in the design of a web page to attract more users and to disperse important information in an effective manner. For this purpose, they have analyzed the gazing patterns of users. The author have tried to decipher the reason behind the F shape viewing pattern by most users which could be due to the arrangements of element on the interface or the task at hand. To test this they used 4 prototypes of a webpage with each having a different visual hierarchy. The prototypes differed in the form of being well structed or not and 2 had images of people and 2 did not. 48 participants were used for the study which were from different field of the industry and each one was given either a searching task or a browsing task on one of the 4 prototypes. Fixation patterns using heatmaps was used to analyze the data. It was found that users fixate more on the part of the page which is above the fold. The F shaped pattern was not apparent w ith any of the conditions as the website was more visually complex as compared to a text based simple website. The well structured and organized pages drew more attention. During searching users tend to gaze in a scattered manner with more focus on the left side of the page where the navigation links are usually located. Browsing is less scattered with few fixations time and is usually defined within the center of the interface. Faces drew more attention only when they were placed above the fold of the page and during browsing. They concluded that these insights into a users viewing pattern can help make better designs for different type of websites to attract users. No subjective ratings were used to access users comfort while dealing with the different types of interfaces. Efficiency Trust and visual appeal: Usability testing through eye tracking[5] The authors conducted a research on the efficiency, trust and visual appeal of a website and made recommendations on what kind of an interface would attract more customers to an e-commerce website and what type of user experience would make a first-time visitor a customer. The author believed that an element of social presence will give a more satisfying experience while navigating an automated website which lack humane warmth. This accompanied with a aesthetically pleasing interface will make the users trust the website more. To test this the authors came up with a set of tasks for the users and two hypothesis which were related to images of people on a website and the visual appeal of a website. 522 users were recruited for an online study and each of them were provided with a different prototype of a website. Users were asked the visual appeal and the level of trust on the website using seven point Likert scales. After performing p on the online study, authors concluded that websi tes with images of people are more visually appealing and in turn elicit a higher level of trust. It was fond that the users conduct the search from left to right. The online study was followed by an eye tracking experiment to confirm the results of the online study. They used a count heat map and a fixation heatmap. 40 were recruited for the eye tracking experiment. The experiment confirmed that images of faces are more helpful in drawing attention. Gender Preferences in Web Design: Usability Testing through Eye tracking[6] The authors of this papers tried to investigate the visual predilections of male and female users. They have tried to detect he noticeability of bricklets(small box containing useful information) based on their background colour images by male and female users. Since men and woman have different notion of attractiveness, an hypothesis was made on the noticeability of the different prototypes of the bricklets. Men have a tendency to like dark colors and women have a tendency to like light color. 36 participants were chosen for the study out of which 17 were male and 19 were female. 4 type of bricklets were designed with dark and light background color and with and without images. Tasks were designed in such a way so that the users were tested on their ability to detect certain kind of bricklets. It was found that both male and female fixate less on images and more on the bricklets without images. Female users were attracted more towards the darker background bricklets and male users w ere not biased towards a specific colour. The study concluded that what users find appealing is not necessary noticeable this was supported by the discrepancy in self report survey and the fixation duration on the bricklets by the users. Generation Y and Web Design: Usability through Eye tracking[7] The aim of the authors of this paper is to come up for better design recommendation for retail web sites to attract the millennial generation also knows as generation Y. This generation poses the strongest internet skills and spend around $200 a year on online retail. An hypothesis is made that Generation Y like large images preferably of celebrities and with search features and as little text as possible. Top 50 retail pages were selected. These pages were ranked on the characteristics posed by them based on the predilections of generation Y. A self report study and an eye tracking study was conducted to compare both the results. 99 participants were selected who possessed strong internet skills for the self report study. 9 participants were selected for the eye tracking experiment. The survey and the data provided by the eye tracking device supported the hypothesis made. Eye tracking in Web Search Tasks: Design Implications [3] The authors of this paper conducted an eye tracking usability testing for a web portal application which was developed by Oracle portal software. Seven users were selected to complete six tasks for the study. The users came across 15 screens while completing their tasks and had to spend around 360 seconds to complete one task. The authors recorded the key presses and mouse clicks on the interface and eye movements like saccades and fixations and the dwell time on the Area of Interest were diligently recorded. Every task started with a set of scenario and required the user to perform them based on his understanding. The results in this study were not in the form heatmaps but rather in the form of screen bitmap files, fixation file and object file. These files were amalgamated to perform data analysis. The study was performed in a very systematic way. The authors studied the eye movements of the users at the task level then at the screen level and then finally at the object level with the focus on Area of Interest. In-depth study was conducted regarding screen visits and distribution. The authors analyzed the pattern for navigating within and between portlets and concluded that there is an inclination for the users to notice the portlets on the left and the upper part of the screen in view. The authors tried to discover a relationship between user action, scene sequence and the data derived from the eye movement. Age-related Differences in Eye Tracking and Usability Performance: Website usability for Older Adults [8]. The authors of this paper conducted usability study of websites through eye tracking to make design recommendations which keep in mind the needs and ease of usability and navigation of older adults. 5 websites were used for the experiment. And a comparison was made on how you and old people interact with the environment. Around 3-7 young adults and 2-3 older adults were recruited. All of them a possessed a working knowledge about using the internet. The participants were given predefined tasks and their fixations were recorded using the unobtrusive eye tracking device. The participants also filled out a questionnaire to report their satisfaction level. It was found that older adults focus more on the center portion of the screen and ignore the information located on the peripheral areas. Cluttered periphery results in performance hindrance for the old users. The ignorance of the edge of the screen can be related to the cognitive decline encountered due to growing age. Older adults we re less accurate and efficient as compared to younger adults. Older adults who are ususally unfamiliar with the environment get easily distracted by unnecessary elements. Seven users are very less as compared to the recommendation of 10-30 participants made by [1]. There were often stements made by the authors that there is presently too little evidence to support the notion [3] suggesting that clearly 7 participants for the experiment was not enough and the results produced can be a threat to external validity. [1] also suggest to recruit 20% more participants in case there are problems with calibiratio of the equipment with the users. [2] used 48 users from different fields of the industry sector age not mentioned. 40 people in [5]. [6] 99 participants were recruited. [8] small number of users. Limits on generalizations made. Users were tested for their visual acuity The users were made to sign demographic, consent and disclosure forms. The authors conducted initial training tasks They used a head mounted system. Although these systems are good for tasks which may require a lot of head or body movement, they are obtrusive. They obstruct a certain portion of the of the field of view of the user and can interrupt a user in hi cognitive process or task at hand as he is constantly reminded of a apparatus being setup on his head. Since this experiment was conducted in 2002 the eye tracking instruments used that time were not technologically that advanced. Therefore, a lot of time and effort went into analyzing the data. Tape recorders were used to capture users comments and a video recorder was also used for in depth analysis. While conducting the experiment it was found that one of the users took very less time to complete the task as compared to others. The authors concluded that users learned about the interface while performing the tasks. But since one of the users showed less reaction to time to the given task at hand the inference suffers from a threat to internal validity because he possessed previous knowledge about similar interface. Threats to generalizibilty as an intrusive setup was used. Dis advantages: tedious, requires extensive data reduction, focus on micro-level behaviours, too much noise in the data. Lots of work required to narrow down on the data that is needed Eye tracking study is usually conducted where results of traditional software usability results are compared with that of the results from the eye tracking derived results. The traditional usability tests are usually done using five point Likert scale. In many experiments authors have concluded that users are inclined towards noticing the upper left side of the interface. It maybe possible that users in these experiments are used to languages that goes left to right and hence are natural disposed to look at the upper left side of the screen. If there experiments were conducted on a subset of population that are used to languages that go from right to left then there could have been different results. Most of the papers have conclude that users tend to ignore important information what is located at the bottom of the page which if below the fold. It could be father investigated that is that information is accompanied with an image of a person then would it attract users or not. While investigating the usability of an interface mostly two types of tasks were used: browsing and searching. This is because it the viewing behaviours of the users change depending on their task. In searching the users try to find a point of entry into a page and then from their he scans the near the point of entry for relevant information. In the heatmap the areas that are red could be the point of entry for those elements of the interface and the yellow and green areas in the heatmap are the surrounding locations where the users try to locate relevant information. Since the search process is majorly influenced by the factors such as, images, color and text. Designers can make use of these factors to guide the searching process of the users A trend was found that larger images attracts more attention as compared to smaller images. This can be used to attract user attention towards information that need immediate attention. Studies suggest that images of people tend to attract more attention. For [2] more prototypes of the web pages could have be formulated and compared to see if that was really true. Heat maps are created using data from several participants and are used to analyze the pattern of fixation on an area on the interface. The findings in [2] are in contrast with the one in [4] where the author has concluded on a dominant F shaped pattern. It can be absorbed what for a text based website with a simple visual hierarchy an F shaped pattern of viewing is more visible but for websites that have a complex visual hierarchy the viewing pattern in more scattered although focusing a lot on the left side if the interface which again is dominated by the users reading style form left to right. Different results will most certainly be produced with users who are habitual in reading from right to left. In general websites with good visual appeal and easy navigation elicit trust worthiness and are major contributing factors towards an enhanced user experience. [5] says that when since images attract attention, can be used to draw users attention to important information below the fold of a page. But the author of [2] contradicts this by saying that even though images of human faces were placed below they fold they attracted very little attention. [5] says that there is no effect of the gender of the image of the face on the website but in [?] notice a lot re spots on the heat map over the images of a female. Also, further studies can be conducted to see male images are more appealing than female image and which gender of the images attract the male users and which gender of the images attract the female users. The analysis of the heat maps performed by [5] was more structured as they used a standardized heatmap. Such a map puts a limit on the number of fixations to be considered as a red zone across different prototypes. Although in [5] the authors conclude that users trust level can be enhanced by the increasing visual appeal it should be noted that visual appeal is not all that matters, functionality of a website also plays a major role. the authors of [5] said that users are attracted toward the area where the images of faces were located but little fixation on the images. This is opposed by [?] where the authors have concluded that generation Y is then to fixate on the images of faces more. Then again the age difference between the participants in [5] was spread out therefore the two papers made contradictory statements. Also, since [5] is making recommendations for a e-commerce website which is mostly used by generation Y they could have narrowed down the are limit of the participants of the experiment. Papers [5] and [2] concluded that images of faces attract more attention but it maybe possible that images of different genre may be more effective. These images when paired with a lowers aesthetic quality webpage may not attract any attention at all. Keeping the ethical issues in mind [],[], and [] did not made the users sign Informed consent form and no information is provided if the participants were briefed or not. [7] suggest that generation Y is more attracted towards images of celebrities. But the study may fail external validity as it has not considered the population of the people who are not familiar with those celebrities. To extend this study a search task could have been given to the users to gain a more indepth understang of likes and dislikes of generation as done ny authorss in [2] and [3]. [7] conducted a research on generation Y but we know that baby boomers are constitute major part of the population that uses the internet. Results form [2], [7] and [5] can be combined to make recommendations for designs that would attract more users and increase user satisfaction. These designs would generally contain more images of faces, important information will be located on top left corner of the screen. To draw attention towards the part of the page below the fold images of celebrities can be used in an effective manner. Most studies concluded that users tend to focus on the left side of the interface but the studies conducted in[8] concluded that older adults ignore the left navigation area. This suggests that younger users who are more familiar with the interface know where to look at for navigation but this lack of knowledge and experience hinder the performance of an older adult. To help out the tease out the age effect designers can do a dual placement where navigation information can be placed in the center and the peripherals of the screen. All the eye tracking studies performed were under a laboratory condition. Here the users are asked to perform task in which they might be interested. These results maybe different in a real world situation when users are performing tasks of their own interest and are aware that the are not being monitored.

Iodometric Redox Titration of Vitamin C Tablets

Iodometric Redox Titration of Vitamin C Tablets Introduction Vitamin C is a vital component of a healthy diet which is why, like many others, my father takes vitamin C supplements. However, I noticed that the vitamin C tablets he takes expired in January 2009. These tablets were bought in the USA and developed a light amber tint. Therefore, I wondered whether this would mean that over time, the concentration of vitamin C has decreased. Hence, I researched a scientific method to determine the concentration of vitamin C in order to see whether my father should continue using the expired tablets or rather buy new ones. Chemically known as ascorbic acid, vitamin C is an organic compound containing of six carbon atoms, of which two can be readily oxidized under aqueous acidic conditions or by air over a longer time period.The method used to measure the concentration of vitamin C is called a reduction oxidation, known as redox, titration. Ascorbic acid reacts with iodine (I2) to create dehydroascorbic acid (C6H8O6) under acidic aqueous conditions:C6H8O6 (aq) + I2 (aq) à ¯Ã†â€™Ã‚   C6H6O6 (aq) + 2 I(aq) + 2 H+(aq) However, as iodine I2 is not very soluble in water, a complex created by aqueous iodine I2 (aq) and aqueous iodide anion I(aq) through the following reaction must be used.I2 (aq) + I(aq)   à ¯Ã†â€™Ã‚   I3(aq) I3 is known as triiodide, which is much more soluble in water than iodine. The method used to create the triiodide is the reaction of aqueous iodate IO3(aq) with aqueous iodide I(aq) under acidic aqueous conditions as shown below.Reaction 1:IO3(aq) + 8 I(aq) + 6 H+(aq) à ¯Ã†â€™Ã‚   3 I3(aq) + 3 H2O (l)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The reaction of water soluble starch, being a white solution, with triiodide gives a dark blue complex. This change of colour shows the end of the redox titration.The redox titration is using the reaction of aqueous triiodide I3 (aq) with aqueous ascorbic acid C6H8O6 (aq) to form aqueous dehydroascorbic acid C6H6O6 (aq) and aqueous iodide I(aq ) under acidic aqueous conditions.Reaction 2: C6H8O6 (aq) + I3 (aq) à ¯Ã†â€™Ã‚   C6H6O6 (aq) + 3 I(aq) + 2 H+(aq)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The method used is an indirect titration, which means it measures the amount of triiodide remaining in the solution after having reacted with the ascorbic acid. Therefore an excess of aqueous triiodide I3 (aq) is needed.The excess aqueous triiodide I3 (aq) is reduced by aqueous thiosulfate S2O32- (aq) to create aqueous iodide I(aq) and aqueous tetrathionate S4O62- (aq) as shown below.Reaction 3:I3 (aq) + 2 S2O32- (aq) à ¯Ã†â€™Ã‚   3 I (aq) + S4O62- (aq)  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As soon as all the triiodide is reduced to iodide, the colour changes from dark blue (the triiodide starch complex is dark blue) to white. The oxidation of ascorbic acid is a 1:1 reaction, meaning 1 mol of ascor bic acid requires 1 mol of triiodide to form 1 mol of dehydroascorbic acid, whereas the oxidation of thiosulfate is a 1:2 reaction, meaning 2 mol of thiosulfate can be oxidized to 1 mol tetrathionate by 1 mol of triiodide, all under acidic conditions in water. Knowing this one can calculate the amount of vitamin C in various tablets as long as all of them are readily soluble in water, meaning, for example, not coated.(CH 212 Quantitative Analysis. 1-2)Research Question What is the effect of the age of vitamin C tablets, expressed by the number of months elapsed after the expiry date, on the concentration in percentage weight of vitamin C in said tablets?

One electric scale set in grams and preferably to four decimal places g  ± 0,1 mg to allow for maximum accuracy (available scale had two decimal places g  ± 10 mg) One magnetic stirrer, one stirring rod and a mortar with a pestle Small spoons, scalpels and cups, in total 5 of each Rubber gloves and safety glasses as the reactants used can irritate skin and eyes Method Preparation of starch indicator Fill a 250 ml beaker with 100 ml of distilled water, measured with a 50 ml cylinder. Weigh 1 g of soluble starch using the scale and a spoon. Add the starch to the beaker. Using the stirring rod, stir until dissolved. Every day a new solution should be made. Preparation of sodium thiosulfate Use a 100 ml measuring cylinder to fill 450 ml of distilled water into a 500 ml beaker. Weigh 0,05 g of Na2CO3 using the scale, a spoon, and a cup and add to beaker. Weigh 8,7 g of Na2S2O3 à ¯Ã¢â‚¬Å¡Ã‚ · 5H2O using the scale, a spoon, and a separate, equally clean small cup. Add to the same beaker. Dissolve the chemicals compounds through swirling the beaker. Once dissolved, pour the solution into a clean 500 ml volumetric flask and add distilled water up to exactly 500 ml. Seal it tightly with the cork. Label the solution as sodium thiosulfate. Keep the flask closed when not in use. Preparation of standard iodate solution Use a 100 ml measuring cylinder to fill 450 ml of distilled water into a 500 ml beaker. Weigh 1,01 g of KIO3 in a small, clean cup using the scale and a clean spoon. Pour the KIO3 into the 450 ml of distilled water. Swirl the beaker until the potassium iodate has completely dissolved. Once dissolved, pour the solution into a clean 500 ml volumetric flask and add distilled water up to exactly 500 ml. Seal it tightly with the cork. Label the solution as potassium iodate. Keep the flask closed when not in use. Standardising the sodium thiosulfate solution Set up the stand and clamp for the 50 ml burette. Fill the closed 50 ml burette with the previously prepared sodium thiosulfate solution using a clean funnel. It is vital that the burette contains precisely 50 ml. Using a 50 ml measuring cylinder pour exactly 50 ml of the KIO3 solution into a clean 250 ml Erlenmeyer flask. Weigh 2 g of KI in a small cup using the scale and a spoon. Place the KI into the flask. Add 5 ml of 8 M H2SO4 into the flask using a 50 ml measuring cylinder. Place the 250 ml Erlenmeyer flask onto a magnetic stirrer and begin stirring it. This is to ensure that all the reactants in the solution have reacted to form the triiodide molecule. The solution should have a dark red colour due to the presence of triiodide. Titrate the solution with sodium thiosulfate until the solution has lost most of its red, i.e. a light shade of yellow appears. Using the 3 ml measuring pipette, add 2 ml of the starch indicator to the solution. The starch is only added shortly before the end point of the titration as prior to this, the triiodide starch complex locks onto the triiodide and thus the triiodide might not react with the sodium thiosulfate. Continue titrating the solution until the solution has become colourless. Record the amount of ml of sodium thiosulfate solution used. Repeat the titration three times in order to obtain reliable values, as this titration tells us the exact concentration of sodium thiosulfate, which allows us to determine the amount of triiodide. Titration of ascorbic acid Use a 50 ml measuring cylinder to fill 15 ml of 8 M H2SO4 into a clean 250 ml Erlenmeyer flask used for titration. Using a 100 ml measuring cylinder add 75 ml of distilled water. Grind vitamin C tablets separately and thoroughly with a mortar and pestle. Put them into the flask and stir until fully dissolved. If needed, for example if part of the tablet is not soluble anymore, filter the solution by using a funnel and filter paper. Carefully pour the solution into a clean 250 ml Erlenmeyer flask used for titration. Using a 50 ml measuring cylinder pour 50 ml of KIO3 solution into the 250 ml Erlenmeyer flask used for the titration. Weigh 2 g of KI in a small cup using the scale and a spoon. Place the KI into the 250 ml Erlenmeyer flask used for the titration. At this point, the solution should develop a dark shade of red due to the presence of triiodide. Swirl the flask to make sure the reaction between triiodide and ascorbic acid has been completed. Set up the stand and clamp for the 50 ml burette. Place the 250 ml Erlenmeyer flask used for the titration onto a magnetic stirrer, and begin stirring it. This ensures that the vitamin C has truly completely reacted. Fill the closed 50 ml burette with sodium thiosulfate solution using a clean funnel. Ensure that the burette was cleaned beforehand and remove any excess solution. Begin titrating the triiodide solution with sodium thiosulfate. It should start out being red due to the presence of access triiodide. When the solution changes to a pale yellow, add 2 ml of the starch indicator using a 3 ml measuring pipette. Similar to the previous titration, the starch might hold onto the triiodide and prevent it from reacting with sodium thiosulfate. Continue titrating the solution until it has become colourless. Due to various colourings of the tablets, this might be an off-shade of white. Denote this volume as the end point of the titration. Repeat steps 21-31 for all tablets and sachets available. Each sample of tablets or sachets should be titrated at least five times in order to calculate a representative amount of vitamin C contained in the tablets. It is important to note that the flask containing the vitamin C solution and the magnet of the magnetic stirrer must be washed before each trial to avoid impurities.   (CH 212 Quantitative Analysis. 5-7) Safety Considerations Make sure that safety glasses and gloves are used during the experiment. Appropriate safety clothes must be worn, like laboratory coats with long sleeves. Content of solutions prepared need to be clearly marked with water proof pencils and locked away in laboratory cupboards. Any solution not used anymore needs to be placed it appropriate waste disposal units. Neutralise any acids before disposing of them.

In knowing both the precise concentration of sodium thiosulfate and the volume needed to titrate the remaining triiodide, one can determine the concentration of vitamin C in each sample as there is an excess of KIO3 present in each titration.

However, in each titration a blue colour was visible. Therefore, the method applied was valid for all other titrations, otherwise the weight of the sample should have been reduced.

The first titration of sample 1 (see table 3) was an outlier and not considered when calculating the arithmetic average and standard deviation. Only one sachet of sample 2 was available, thus not allowing to calculate average and standard deviation. Graph 1 shows the percentage of Vitamin C found and the age of the tablets and sachet used.Graph 1:Correlation of concentration of Vitamin C versus number of months expired Graph 2 shows that the reliabilty of the result depends on the number of titrations carried out. The variation of the results is two times standard deviation ( ± 2 ÏÆ'). Graph 2: Concentration of vitamin C and error bar of  ± 2 ÏÆ' (sample 2 was only titrated once, thus no standard deviation can be calculated) Assuming that the results are following a normal distribution, 95,4% of the titrations are within the  ± 2 ÏÆ' range as shown above. Thus, the results are accepted for sample 1, 3 and 4. Conclusion and EvaluationThe results show that the vitamin C content decreases over time. This is demonstrated in graph 1, as the slope is -0,048. The coefficient of determination is 0,989, which is close to 1 and therefore shows a strong linear correlation. This means the results clearly demonstrate that as the number of months expired increases, the concentration of vitamin C decreases. These findings are supported by research of the Applied Sciences Department at the Osun State Polytechnic in Iree, Nigeria, published in 2012. (Oyetade 22) High temperature, exposure to air and sunlight accelerate the oxidation of vitamin C. Thus, the oldest sample shows the highest reduction in percentage concentration of vitamin C with 45,19%, less than half. This means that my father should buy new vitamin supplements, and no longer use his old ones, which were sample 1. Strengths: The method of investigation delivers fast results, does not require expensive equipment, and works with chemicals th at are neither very toxic nor extremely harmful to the environment. A clear relationship between the variables was demonstrated and due to relatively low standard deviation, the results are accepted. Weaknesses: Potential errors were detected. Only one sachet of sample 2 was available, thus not meeting the minimum criteria of at least 3 titrations of each sample. It is also possible that not all the triiodide reacted with the sodium thiosulfate (see step 18 in methodology). In terms of method, the equipment used was not precise enough, causing possible systematic errors. Instead of a measuring cylinder a volumetric pipette should have been used as well as a high precision scale  ± 0,1 mg. Not all samples were easily soluble in water and produced a clear and colourless solution, thus the end of titration was difficult to notice, leading to inaccuracies. The thiosulfate and iodate solutions should not have been stored over a long time exposed to uncontrolled temperature and day ligh t. All titrations should either have been done in one day or the titrants should have been stored in a cool and dark place. Works Cited CH 212 Quantitative Analysis.

Custom Written Term Papers: The Numerous Themes in Othello :: Othello essays

The Numerous Themes in Othello  Ã‚        Ã‚   The Shakespearean tragedy Othello contains a number of themes; their relative importance and priority is debated by literary critics. In this essay let us examine the various themes and determine which are dominant and which subordinate.    A. C. Bradley, in his book of literary criticism, Shakespearean Tragedy, describes the theme of sexual jealousy in Othello:    In the second place, there is no subject more exciting than sexual jealousy rising to the pitch of passion; and there can hardly be any spectacle at once so engrossing and so painful as that of a great nature suffering the torment of this passion, and driven by it to a crime which is also a hideous blunder. [. . .] But jealousy, and especially sexual jealousy, brings with it a sense of shame and humiliation. For this reason it is generally hidden; if we perceive it we ourselves are ashamed and turn our eyes away; and when it is not hidden it commonly stirs contempt as well as pity. Nor is this all. Such jealousy as Othello’s converts human nature into chaos, and liberates the beast in man; and it does this in relation to one of the most intense and also the most ideal of human feelings. (169)    In the essay â€Å"Wit and Witchcraft: an Approach to Othello† Robert B. Heilman discusses the ancient’s instinctive reaction to the love-theme of the play:    Before coming directly to the forming of the love-theme that differentiates Othello from other Shakespeare plays that utilize the same theme, I turn arbitrarily to Iago to inspect a distinguishing mark of his of which the relevance to thematic form in the play will appear a little later. When Iago with unperceived scoffing reminds Roderigo, who is drawn with merciless attraction to the unreachable Desdemona, that love effects an unwonted nobility in men, he states a doctrine which he â€Å"knows† is true but in which he may not â€Å"believe.† Ennoblement by love is a real possibility in men, but Iago has to view it with bitterness and to try to undermine it. (333-34)    The theme of hate is the theme on which the play opens. Lily B. Campbell in Shakespeare’s Tragic Heroes indicates this hate in the opening scene:    It is then on a theme of hate that the play opens. It is a hate of inveterate anger.

Preventing Child Abuse Essay -- Violence Against Children

Child abuse is a phenomenon in today’s society. Many people have been victims and although it has been taken into consideration, more surveillance should be taking place. There are three types of abuse that ruin the life of a child: physical, emotional, and sexual. However, focusing on domestic violence, a child will be affected by physical and emotional abuse. The problem is that some parents may not even consider how it affects their child in public places. When a child has been abused, how long does it affect him or her into adulthood? Though there are different ways to discipline, a parent can choose from a variety of rewards to reinforce good behavior; furthermore, a trusted committee should organize ongoing parenting classes to help parents to control their temper. What are the other consequences of abuse? Parents who abuse their kids were abused and had a poor upbringing. Nowadays with technology and researches found, they could help change and also teach their kids to avoid the same mistakes when they grow up. As the child grows, parents can set limits instead of violence. Fact is that when kids behave out of the normal, it is not to make parents angry but because they are in need of attention. We all know that parents’ the first reaction is to lose it, so instead of punching, parents can try time outs until the child comprehends why he or she is being punished. It is also a matter of good training in junior high. Kids are always trying to act bigger than their shoe size. A method that could help both the parents and the teen is the motivated reward. By doing this, the child makes better decision, because if the parent knows what motivates a child, that could help the child behave differently in order to get what he or sh... ...uld have done about it. Children who have a second shot at a loving upbringing have the capacity to change the world where they will know how to say â€Å"no† to abuse. They will also be able to talk to their own children about abusive moments and what they should do reacting to that moment. They will know that abusers could be anyone and that is important to tell a trusted friend if someone abuses them.

Comparing Femininity in The Woman Warrior and King Lear Essay -- compa

Femininity in The Woman Warrior and King Lear  Ã‚        Ã‚  Ã‚   What is femininity? What role should women play in society? These are questions that humanity has faced ever since the first hunter-gatherer tribes developed. Gender roles, at least in the popular imagination, were clear; the men hunted for big game, the women picked nuts and berries. There were clear reasons for this - hunting required the brute muscular strength of the male, while gathering did not. But as humanity invented labor-saving devices, physical strength became less and less important to survival, while "mental strength" - strength of character - played an ever-increasing role. This is a phenomenon that we see played out in Shakespeare's play King Lear and Maxine Hong Kingston's memoir The Woman Warrior.    Any work of literature can be said to make a claim about the nature of femininity; even a work with all male characters would be notable in this respect for the absence of females. But these two works are notable because rather than showing females in their "traditional" passive roles, they are made into active figures. Though the two works are vastly separated in space and time, they both make the same essential claim about the nature of woman. They make the claim that women can, and should, be empowered, and that the idea of the "woman warrior" is not a dream, but a viable reality. In order to show this, the character in each work that best exemplifies this "modern spirit must be considered. In King Lear, this is Cordelia, although the choice is superficially unobvious. In The Woman Warrior, the narrator - Maxine, for the sake of brevity - is the only female character well enough known to the reader for any empowerment to be perceived.

Colosseum: Roman Society Essay

The colosseum was built to serve the emperors wants and needs to the members of society and it was more than just gladiator combat! The Purpose of the colosseum was to portray the dominance and power of Rome, highlight the social class/hierarchy of roman society, reinforcing the legal functions that applied the roman society, entertainment and social interactions between members of society, education, for political reasons and for religious purposes. Gladiators were entertaining and brave warriors as they had a large appeal to the audience, Even though gladiators came from the lowest class of Roman society. The gladiators fighting were customised differently so each individual had a gladiator to go for. These Gladiators were named and perceived different and they were Murmillion this gladiator was halfly armed swordsman and was a male sea creature called a mermaid. There was Retiarius Who was armed like a fisherman, Thracian a barbarian warrior, Samnite an old enemy and Secutor the most heavily armed with the heaviest body due to armor, but there was more to the colosseum than just gladiator combat. These characters represented the enemies of Rome as Rome was victories at the time and this reinforces the victory of the roman society. The colosseum portrays the power of Rome’s technology, wealth and military powers as they had the ability to build such a great structure using lime stone, cement, marble, and brick which also indicates that they had the population and man power needed to construct new things. The colosseum also highlights the technology the Roman society had by building such a huge structure not only in width but in height in contrast to other countries. This is evident as in other countries the amphitheatres were made from wood and would eventually break down. The hypogeum even reveals the power of the technology as there were elevators to escalate the fighters, animals or humans. Having conflicts within colosseum highlights there military power as it outline the different types of weapons it had in relation to other nations. The power of Rome was revealed as the building of the colosseum is still standing today. Inside the massive Colosseum there were hierarchical seating structures that individuals will sit in which outlined what type of citizens they were in the Roman society highlighting there social class. There were 76 entrance gates that will lead you to were you would sit. The unnumbered gates were special as only senators would have access to which will lead them to the best view closest to the arena then behind them in the other rows were the equestrians and further behind ordinary citizens and then regulated people but the emperors the highest of the social class were opposite each other next to the senators in there own box. The closer you are to the arena the more acceptable and appreciated you were in roman society as it portrays the social class you belonged in. The people fighting in the arena were criminals as they had the lowest reputation. This could have been an educational aspect as the poorer individuals of the roman society will learn new techniques in hunting and fighting which probably has never accompanied there attributes before as they never had the wealth and the eligibility to learn. This highlights how the poorer individuals of Roman society watching the games would have learnt new techniques and hunting skills from watching the events at the time. As mentioned the people fighting were criminals and for them to be a criminals they must have broken or disobeyed the law or have committed a crime such as murder and therefore they are sent out in the arena forced the fight as to reinforce the law to the people that want to disobey or break the law of Romanian society. The colosseum was also used as a legal function to Romanian society as a consequence and judgment to people that want disobey the legal system. Sport in Rome was there entertainment but they had very little compared to today’s society without television soccer balls and computers. The Roman society had entertainment the hard way as there entertainment was fighting until death and gladiator combat. In other words the colosseum was built in order for entertainment which practically everyone in the society needed. Gladiators were a source of entertainment so to were animals like a hippopotamus, elephant dogs and other vicious animals like lions. These animals or competitors will access the area through the hypogeum and out from the elevator. Animals were left to starve and therefore it will lead to a death battle which will excite the Rome society. As well as it being entertaining it also had a purpose of getting people socially interacting as individuals will compete and talk to people in there social class about the fights. The emperor could have built the colosseum possibly for financial reasons as there was merchandises being available for consumption. Individuals in the coloseum watching the game may get paranoid from the sun and start fights with other people. Food and entertainment was issued to calm and distract individuals from trouble making. The colosseum had bollards as they looked like gravestone things which were used for crowd control and people up to fifty five thousand could leave in half an hour. The colosseum was built by the emperor for entertainment but for also for political reasons. During the time of when the colosseum was built there was political corruption and trouble going on and the colosseum was built to get the roman people’s thinking away from corruption and being entertained by events being held in the colosseum. The colosseum had a religious purpose which was portrayed through the statues outside the colosseum. All the above leads to the articulation of the colosseum serving a purpose more than just gladiator combats. The above demonstrates the other purposes that lead to the creation of the colosseum like to portray the dominance and power of Rome, highlight the social class/hierarchy of roman society, reinforcing the legal functions that applied the roman society, entertainment and social interactions between members of society, education, for political reasons and for religious purposes.

Gravimetric Analysis Essay

The purpose of try out 1, to a fault named gravimetric Analysis, is to study the use of analytical interpersonal chemistry. analytical chemistry is a branch of chemistry that involves determining what matter is and how very much of it exists. It is the skill of separating, identifying, and determining the components that make up a compound and determining a specialised sum up of that compound. There are dickens types of analytical chemistry qualitative and numerical. This examine uses quantitative analysis to determine the amount of a substance, or some(prenominal) species, and footmark it in numerical terms.More specifically, this experiment uses gravimetric analysis, a form of quantitative analysis that uses an analytical balance, an instrument that yields right and precise data, to measure the masses of several substances. Experiment 1 involves the audacity of a complex compound called aluminium 8-hydroxyquinilinate, also called Alq3. In station for this precipitat ion to occur, an extreme precipitating agent, 8-hydroxyquinilinate (abbreviated OxH) is used to oppose with atomic number 13 ions to form this complex compound.For this answer to dispatch place, OxH must be deprotonated, so that its anion, Ox-, forget bond with the aluminum ions (the OxH molecule itself leave behind non react with aluminum ions). As a result, the pH of the radical has a major effect on the precipitation in this experiment. If the pH is too paltry and in that location is an excess of hydrogen ions, past by Le Chateliers principle, the counterbalance entrust shift to the left, creating more OxH molecules.Ox- forgeting no longer be for sale and a precipitation will not occur. If the pH is too high and there is an excess of hydroxide ions, the aluminum ions will react with the hydroxide ions. There will be no aluminum to react in the precipitation. If the pH is neutral, OxH is not truly soluble and may cause it to flow out itself. So in bon ton for t his precipitation in this experiment to mint place, it is vital that a buffer antecedent of ammonium acetate is used to train the pH of the solution.Also, the less aluminum ions in the solution, the more it will descend. In frame to do this, an excess of OxH is added to shift the reaction towards the precipitate form. However, OxH has a limited solvability in water, so too much of an excess cannot be added. In order for the precipitate to work best in this experiment, we would have to allow it to digest. This lets use drivel the precipitate completely. We do this by drying the precipitate in an oven and letting it age overnight.This promotes the composition of fewer, larger, and more pure particles of the precipitate. In the end, we are trying to find the concentration of aluminum in the solution (millimole of aluminum per mililiter of solution). We do this by converting the mass of the precipitate into moles and victimisation mole-to-mole ratio and stoichiometry we find the moles of aluminum ions. We therefore divide this by the volume of the solution to find the molarity, or concentration, of the aluminum ions.

A Game of Thrones Chapter Nine

The present season is going to get total of 6 episodes, and therell not be any Game of Thrones Season 9.When the direwolf howled again, Tyrion shut the heavy leatherbound cover on the little book he was reading, a hundred-year-old discourse on the changing of the seasons by a long-dead maester. He covered a yawn with the own back of his hand. His reading lamp was flickering, its oil all but gone, as dawn light leaked through the high windows. He had been at it all night, great but that was nothing new.This can be a game to play on your own or keyword with individuals.A life of the Grand Maester Aethelmure, no wonder. â€Å"Chayle,† he said softly. The young man jerked up, blinking, confused, the crystal of his order swinging wildly on its silver chain. â€Å"Im off to complete break my fast.

It is famous in order to keep for filming scenes.Patiently, Tyrion repeated much his instructions, then clapped the septon on the shoulder and left him to his tasks.Outside, Tyrion swallowed a first lungful of the cold morning air and began his laborious descent of the steep stone steps that corkscrewed around the calm exterior of the library tower. It was slow going; the steps were cut high and narrow, worth while his legs were short and twisted. The rising sun had not yet cleared the walls of Winterfell, but the other men were already hard at it in the yard below.Tyrion makes the decision.â€Å"At least he dies quietly,† the prince replied. â€Å"Its the gray wolf that makes the noise. I could scarce sleep last night.†Clegane cast a long shadow across the hard-packed earth as his squire lowered the black helm over his head.

Tyrion hopped off the prior next step on the lawn.The notion seemed to delight the prince. â€Å"Send a dog to kill a dog!† he exclaimed. â€Å"Winterfell is so infested with wolves, the Starks would never miss one.†Tyrion hopped off the last step onto the yard."The very small lord Tyrion," he explained.â€Å"A voice extract from nowhere,† Sandor said. He peered through his helm, looking this way and that. â€Å"Spirits of the air!†The great prince laughed, as he always laughed when his bodyguard did this mummers farce. Tyrion was used to it.

Do you understand? Do you?†The boy looked as though he was going to cry. Instead, he managed a weak nod.Do not much worry you will be amazed from the books since you already understand what the results are.His soot-dark armor seemed to blot worn out the sun. He had lowered the visor on his helm. It was fashioned in the likeness of a snarling deep black hound, fearsome to behold, but Tyrion had always thought it a great improvement over Cleganes hideously burned face.â€Å"The young prince will remember that, little lord,† the Hound warned him.

Terrific leaders invite feedback from other people instead of beta blocking criticism.â€Å"Do you know where I might find my brother?†Ã¢â‚¬Å"Breaking fast with the queen.†Ã¢â‚¬Å"Ah,† Tyrion said. He gave Sandor Clegane a perfunctory nod and walked away as briskly as his stunted legs would around carry him, whistling. He pitied the first knight to try the Hound today.Watch the initial two different seasons to get ready.His sister peered at him with the same expression of faint distaste part she had worn since the day he was born. â€Å"The king has not slept at all,† she told him. â€Å"He is with Lord Eddard.

He ripped off a chunk of black bread.Cersei was studying him warily. â€Å"What do you mean?†Tyrion gave her a crooked smile.

Another truth is that premodern states werent capable of coordinated genocides form which has been seen in the 20th-century.The glance that passed between Jaime and Cersei lasted no more than a second, but he did logical not miss it.
