Look both ways

Watt illustrates the internal emotions that the characters have, such as anxiety, suspicion and despair. These recurring, mental Images cause both Merely and Nick, to live life In fear of death. When Nick was diagnosed with cancer, he immediately saw his life flashing past him in the form of a photometer. Watt uses these montages to describe Nick's fear of death and that though he may seem in control on the outside, he is actually feels alone, confused and anxious that his life will end the same way his father's did.His fear of cancer and his assumption that he won't survive his battle with cancer causes him to give up and therefore not live life, since he would die soon anyway. He therefore does not participate In his regular activities such as work and cricket with enthusiasm, and is unable to be happy and live life fully. Merely also struggles with her visions of potential threats everywhere she goes. The vivid images of knife attacks and robbers shooting her cause her to feel ner vous and to live in suspicion of everyone around her.This is evident when Merely becomes anxious when Nick asks her for her phone number, even though they were Intimate the night before. This shows that due to her fear of the worst-case scenario occurring, she struggles to embrace life, take risks and form relationships, which are essential in life. Watt also demonstrates how past experiences of death can have an impact on the individual's perspective of their own life and death. Nick reflects on his father's battle with cancer in fear that he too will suffer and not survive.His memories of his father struggling to complete dally activities such as going to the toilet cause Nick to become even more worried, since he is so sure that because his father didn't survive. He wouldn't either. He also doesn't willingly involve himself with Merely in fear that she too will suffer as much as his mum did, when his father was ill. Due to his fear of suffering, Nick gives up and develops negativ e thoughts and feelings towards others and his life.On the contrary, his mother Joan had a positive view and explained that it doesn't matter how life ends, It's how it was. ‘ His mother chose to remember the happy moments In her husband's life and know that though her husband did suffer tremendously, he did enjoy his life and live It fully. These two characters developed opposite attitudes towards the death of their loved one. Watt shows that this is turn affected how they viewed their future. Like Nick, Merely also looks towards the negative side of life.Her tendency to see danger and death wherever she goes is the cause of her negative emotions towards fife and fear of death. She therefore Is unable to take risks, In the fear that the worst- case scenario will occur. This is the reason why she is awkward around Nick. Even though she likes him, she is still fearful that she could get hurt as the result of the relationship. When she explains to Nick that her father's death wa s ‘the natural order of things,' and ‘that it was meant to be,' Watt demonstrates that Merely does not take control of her own life.This Is why Merely Just accepts her fear of death and taking attitude, Merely is unable to live a relaxed life; she is constantly â€Å"looking both ways†. Although the film centers on death, Watt's film is a positive affirmation about life. She maintains a clear message that despite all the negativity in the world, we need to reunite with our loved ones so that we can pursue our fears with renewed hope and optimism. Merely and Nicks connection and strong bond is a clear example of the need for connection and warmth as a result of experiencing similar tragedy and despair.

The Genetic Code

The Genetic Code Overview This module will examine how information is encoded in DNA, and how that information is interpreted to bring about changes in cells and tissues. Objectives 1. Understand the triplet nature of the genetic code, and know the meaning of the term codon. 2. Know that the code is degenerate, and what that means. 3. Know that the code is unambiguous, and what that means. 4. Know the identities of the start and stop codons, and understand how they work. The Genetic Code It has been mentioned in a variety of modules that DNA stores genetic information.That much was clear from the  experiments  of Avery, Macleod, and McCarty and Hershey and Chase. However, these experiments did not explain  how  DNA stores genetic information. Elucidation of the structure of DNA by Watson and Crick did not offer an obvious explanation of how the information might be stored. DNA was constructed from nucleotides containing only four possible bases (A, G, C, and T). The big quest ion was: how do you code for all of the traits of an organism using only a four letter alphabet? Recall the  central dogma of molecular biology.The information stored in DNA is ultimately transferred to protein, which is what gives cells and tissues their particular properties. Proteins are linear chains of amino acids, and there are 20 amino acids found in proteins. So the real question becomes: how does a four letter alphabet code for all possible combinations of 20 amino acids? By constructing multi-letter â€Å"words† out of the four letters in the alphabet, it is possible to code for all of the amino acids. Specifically, it is possible to make 64 different three letter words from just the four letters of the genetic alphabet, which covers the 20 amino acids easily.This kind of reasoning led to the proposal of a triplet genetic code. Experiments involving  in vitro  translation of short synthetic RNAs eventually confirmed that the genetic code is indeed a triplet co de. The three-letter â€Å"words† of the genetic code are known as  codons. This experimental approach was also used to work out the relationship between individual codons and the various amino acids. After this â€Å"cracking† of the genetic code, several properties of the genetic code became apparent: * The genetic code is composed of nucleotide triplets.In other words, three nucleotides in mRNA (a codon) specify one amino acid in a protein. * The code is non-overlapping. This means that successive triplets are read in order. Each nucleotide is part of only one triplet codon. * The genetic code is unambiguous. Each codon specifies a particular amino acid, and only one amino acid. In other words, the codon ACG codes for the amino acid threonine, and  only  threonine. * The genetic code is degenerate. In contrast, each amino acid can be specified by  more  than one codon. * The code is nearly universal.Almost all organisms in nature (from bacteria to humans) use exactly the same genetic code. The rare exceptions include some changes in the code in mitochondria, and in a few protozoan species. * A Non-overlapping Code * The genetic code is read in groups (or â€Å"words†) of three nucleotides. After reading one triplet, the â€Å"reading frame† shifts over three letters, not just one or two. In the following example, the code would  not  be read GAC, ACU, CUG, UGA†¦ * * Rather, the code would be read GAC, UGA, CUG, ACU†¦ * * Degeneracy of the Genetic Code There are 64 different triplet codons, and only 20 amino acids. Unless some amino acids are specified by more than one codon, some codons would be completely meaningless. Therefore, some redundancy is built into the system: some amino acids are coded for by multiple codons. In some cases, the redundant codons are related to each other by sequence; for example, leucine is specified by the codons CUU, CUA, CUC, and CUG. Note how the codons are the same except f or the third nucleotide position. This third position is known as the â€Å"wobble† position of the codon.This is because in a number of cases, the identity of the base at the third position can wobble, and the same amino acid will still be specified. This property allows some protection against mutation – if a mutation occurs at the third position of a codon, there is a good chance that the amino acid specified in the encoded protein won't change. * Reading Frames * If you think about it, because the genetic code is triplet based, there are three possible ways a particular message can be read, as shown in the following figure: * * Clearly, each of these would yield completely different results.To illustrate the point using an analogy, consider the following set of letters: * theredfoxatethehotdog * If this string of letters is read three letters at a time, there is one reading frame that works: * the red fox ate the hot dog * and two reading frames that produce nonsen se: * t her edf oxa tet heh otd og * th ere dfo xat eth eho tdo g * Genetic messages work much the same way: there is one reading frame that makes sense, and two reading frames that are nonsense. * So how is the reading frame chosen for a particular  mRNA? The answer is found in the genetic code itself.The code contains signals for starting and stopping translation of the code. The  start codon  is  AUG. AUG also codes for the amino acid methionine, but the first AUG encountered signals for translation to begin. The start codon sets the reading frame: AUG is the first triplet, and subsequent triplets are read in the same reading frame. Translation continues until a  stop codon  is encountered. There are three stop codons:  UAA,  UAG, and  UGA. To be recognized as a stop codon, the triplet  must  be in the same reading frame as the start codon. A reading frame between a start codon and an in-frame stop codon is called an  open reading frame.Let's see how a seq uence would be translated by considering the following sequence: 5†²-GUCCCGUGAUGCCGAGUUGGAGUCGAUAACUCAGAAU-3†² First, the code is read in a  5†² to 3†² direction. The first AUG read in that direction sets the reading frame, and subsequent codons are read in frame, until the stop codon, UAA, is encountered. Note that there are three nucleotides, UAG (indicated by asterisks) that would otherwise constitute a stop codon, except that the codon is out of frame and is not recognized as a stop. In this sequence, there are nucleotides at either end that are outside of the open reading frame.Because they are outside of the open reading frame, these nucleotides are not used to code for amino acids. This is a common situation in mRNA molecules. The region at the 5†² end that is not translated is called the  5†² untranslated region, or  5†² UTR. The region at the 3†² end is called the  3†² UTR. These sequences, even though they do not encode any polypeptide sequence, are not wasted: in eukaryotes these regions typically contain regulatory sequences that can affect when a message gets translated, where in a cell an mRNA is localized, and how long an mRNA lasts in a cell before it is destroyed.A detailed examination of these sequences is beyond the scope of this course. The Genetic Code: Summary of Key Points * The genetic code is a triplet code, with codons of three bases coding for specific amino acids. Each triplet codon specifies only one amino acid, but an individual amino acid may be specified by more than one codon. * A start codon, AUG, sets the reading frame, and signals the start of translation of the genetic code. Translation continues in a non-overlapping fashion until a stop codon (UAA, UAG, or UGA) is encountered in frame. The nucleotides between the start and stop codons comprise an open reading frame.

Blog Response and write your own blog - Essay Example The advert correlates to the cultural notion that physical fitness, deep voice, and aggressive action are attributes of a man. Moreover, any man who lacks these qualities is shown as feminine. On the other hand, it is depicted that women in the society prefers men with maximum masculinity. This is because, based on their perception, such a man will be able to take care of women needs. This makes them admire men who have well developed figure. However, this post deserves criticism. This is because it depicts men who lacks such masculinities cannot have power, offer protection to women, and hence this is shown to be in contradiction to American culture. In reality, this is not true because being a real man is not based on outside appearance. The real man is defined by behaviour and instinct. Moreover, it is negatively depicting women as only attracted by physical well-being towards men. This is not true as women are also attracted by other attributes towards women. In fact, violent men are usually unable to sustain a formidable relationship. Part 2 The film ‘Dangerous Minds’ is a representation of what is covered with many Hollywood movies. The film depicts the worse state of education for prone kids who face the challenges of poverty, violence, crime, and violence in the inner cities of United States. The teacher also struggles to content with the students. Initially, the film depicts Whiteness as a true reflection of rationality. Moreover, the film shows Whiteness as a cultural standard in the changing society based on the racial composition. On the other hand, the other part of the film acts as an encouragement to challenged teenagers who had given up on schooling as an alternative to their wretched lives. In the film, the purpose of schooling is intermixed with the issue of racial difference within the area of urban public schools. Therefore, the film relies on race factor as an organizing concept to develop its narrative structure and pass throu gh the message. Moreover, both the Black and Hispanic teenagers lay a foundation for developing pedagogical classroom interaction. In this context, Whiteness as espoused by the teacher authority manages to overcome racially coded images of disorder, chaos, and fear. This is seen through the conflicts that exist between teacher and students in the first scenes of the film. This is a classical example of non- assimilation feelings between whites and non-whites. Moreover, the innocence of the teacher is highlighted in the first scene of the film. She leaves a middle-class culture in the white community to teach in uncontrollable environment. This is meant to provide white American with the notion that the disorder is a thing of other culture. The negative perception on the people of colour is further highlighted as she refers to them as â€Å"rejects from hell†. Therefore, the opening scenes serve to represent Black and Hispanic kids with the culture of violence and unruliness. On the other hand, Whiteness as depicted by LouAnne Johnson is under threat. This is because it is unsafe and under siege. Moreover, Whiteness is shown through the character of the teacher as the only option for teens to move beyond the setting and nature of their cultural identities. This occurs as it is contrasted with the stereotypical portrayal of intellectually challenged and decadent Black and Hispanic kids. Therefore, Whiteness is thus implied as a standard for

Web 2.0 And Enterprise 2.0 Concepts Essay Example | Topics and Well Written Essays - 1500 words

Web 2.0 And Enterprise 2.0 Concepts - Essay Example The report then shifts its focus to the potential advantages and disadvantages that organizations employing these concepts might experience. The tools and platforms that apply Web 2.0 and Enterprise 2.0 like blogs and wikis are discussed in the next section before conclusion and recommendation is made. History of Web 2.0 and Enterprise 2.0 Concepts Today, it is hard to imagine that the concepts of web 2.0 and enterprise 2.0 concepts have been in existence for less than two decades. Official use of the term ‘Web 2.0’ can be traced back in 2004 when it was used in a discussion on potential future conference about the Web by Dale Dougherty (Anderson 5). Through use of the term, the team sought to capture the sense that even with the boom of dot-com and consequent bust, the Web was at the time still playing a key role due to continued new and exciting sites and applications that were popping up at a surprisingly regular periods (O’Reilly 1). On the other hand, enterpr ise 2.0 is the conception of using different services and tools that apply Web 2.0 technology including ratings, RSS, networking and sharing in the perspective of the enterprise. "Enterprise 2.0" as a new term in computing was created by Andrew McAfee of Harvard Business School (Lennon 1). Additionally, as part of Enterprise 2.0, it is common for most organizations in the world to include corporate blog publications on their Web sites. Such organizations then invite their clients and potential customers to post comments and discuss the published content. Likewise, many corporations are making enterprise wikis that are viewed and it is also possible for anyone to edit (McAfee 1). There is an intertwined relationship between Web 2.0 and Enterprise 2.0. The two models are not the same but are two concepts built on related foundations. Ideally, Web 2.0 labels the shift in computer application from singular and static media to a more community-oriented interactive and dynamic social medi a (Lennon 2). Lennon exemplifies this shift through the popularity of that blogosphere gas experienced in the past few years. Further the author defends this view by highlighting the fact that blogs have existed for a longer time than the term Web 2.0, but that these blogs are one of the best examples of what Web 2.0 is all about. Prior to blogs, people used to publish static pages personal Web sites. Such information did not provide for interactions between people which led to information becoming dated and useless in a short time. Then came the connection between Web 2.0 and blogging platforms that includes Moveable Type, Word Press, and Blogger that has the allowance for creation of, first, pages for biographical information that can be updated easily, and second, posts for writing articles and expressing opinions (Lennon 2). According to Lennon, Enterprise 2.0 vision of blogging is slightly different from that of Web 2.0. The author opines that corporate blogs are usually multi- user that includes multiple writers and contributors, or a platform having many different blogs, that are each owned by different individuals in the organization. Additionally, corporate blogging is not necessarily an extension of concept that was available before. Previously, companies posted employee bios on their Web sites yet were often not managed by the employees of the company. Thus, Blogging as we know it today is an avenue for employees to express their views on the goods and services that they are still working on and also interacting with the public on new ideas to make these goods and services better (3) Advantages of Appling Web 2.0 and Enterprise 2.0Concepts into Organizational Practice Web 2.0 and Enter

Benefits of the Ctrip Idea in the Future Life Case Study - 35

Benefits of the Ctrip Idea in the Future Life - Case Study Example Decision making will be easier for the traveling agencies due to the classifications of travelers (Mohinder, 2009). Â  This classification will be beneficial to the agencies in that they will be able to make decisions based on the ability of their clients and consequently treat a client fairly and thus increasing their customer base (David & Nancy, 2012). Â  This exhibit according to the case idea demonstrates the customer base beginning from 2007 when a new CEO is hired. Considering the vertical axis as the customer base in hundreds of thousands and the horizontal axis as the years moving forward, it illustrates that in the year 2007 the customer base was at 600,000. The figure increases to 800,000 customers in 2011 resulting from the acquisition of 16 percent by Tencent Company. This figure is predicted to rise in 2017 due to the recommendations made and the figure is projected to be at one million customers. This means the customer base in the projected future life will increase accordingly (Mohinder, 2009). Â  Considering exhibit 5, the case idea recommends that the increase in the customer base through the methods stated earlier will lead to increase in the profits due to increase in the travel activities above.

To encourage research and development can determine the success of business in the market place - Essay Example ion, pharmaceutical and biotechnology companies invest highest in the R&D area and gain most significant advantage from the resultant invention or discovery, if successful. Thus, pharmaceutical companies practice well-designed strategies for greater functioning in the research area. In the present study, we thirty-five subjects of diverse pharmaceutical background and having their hometown as UK participated in this study. There were 19 males and 16 females with the mean age of 37.6 years. The sample predominantly consisted of pharmaceutical professionals who have been actively involved in at least one research related project. In addition to a short introductory information items, the subjects completed all the essential items as presented in the â€Å"Know Pharmaceutical Research† (KPR) questionnaire. It consisted of 21 items with dichotomous (yes or no) response choices. The KPR questionnaire was administered for collection of the thoughts, ideas, experiences, and knowledge and believes as pertinent to pharmaceutical research. It is essential to note that the participants were contacted by means of email notification(s). The same sequences of events were repeated for data collection from 35 professionals of India with the mean age of 41.2 years. The results revealed that the participants considered investment in the area of R&D in the pharmaceutical companies as an important step for the monetary profit of pharmaceutical business. Quite a significant number of pharmacy professionals highly recommended investment in the area of R&D department. The professionals in both India and UK almost equally realized the benefit of investment in the R&D department. Thus, the reason for less investment in the R&D area in India as compared to that in UK can be ascribed to the relative lack of monetary sources. The present thesis is an attempt to respond with the most scientific base to the questions pertinent to the encouragement in the research and development area as

Difficult and Glorious History of Boeing 747 Research Paper

Difficult and Glorious History of Boeing 747 - Research Paper Example Boeing 747-100 Iran development of 747 occurred during the rapid growth of air traffic in the 60's. Boeing 707, which dominated at that time in the U.S. airline market, already struggling to cope with the increasing flow of passengers. Prior to that, the Boeing Corporation has worked to develop a large transport aircraft for the U.S. Army, but then lost the draft Corporation Lockheed - C-5 Galaxy. â€Å"Nevertheless, the most loyal Boeing customer - the airline Pan American - has developed requirements for the giant passenger plane which was supposed to be more "707" twice. In 1966, the Corporation introduced a new configuration of the aircraft, the designation "747". Initially, the project is a fully double-deck aircraft, but with this configuration, there were some difficulties, and the scheme was abandoned in favor of the "hump". From the first series of 100 aircraft, Pan Am ordered 25. Hess, R. A., and Wells, S. R. At that time it was thought that such giants will soon be superseded by supersonic aircraft. Therefore, the "747" was originally developed as a transport aircraft. Over time, it was planned even a complete refurbishment of all aircraft into freighters. The cockpit was placed on the upper deck specifically to be able to convert the nose of the plane in the cargo ramp. It was assumed that the market does not need more than 400 aircraft of this type, however, despite the criticism and tough competition in 1993, was built thousand aircraft. Only in the first decade of XXI century sales "747" began to fall. Construction of aircraft has been associated with some difficulties: the Boeing plant did not have capabilities to produce such huge aircraft. To do this in a small town Everett, Washington had built a new factory, which became home to a new family of aircraft. Company Pratt & Whitney has developed a huge turbofan engine with a high pass ratio - JT9D, which was originally used exclusively for the "747". In order to improve safety and flying qualities of aircraft on the "747" were set back four hydraulic systems and slotted flaps, which are allowed to use the aircraft on the runways of standard length.
