Proposed Design Sources Of Data - 1586 Words

Proposed Design Sources of Data For the initial phase of this exploratory study regarding completion rates, data sets are available through different internet sources that contain all ex post rates. These data sets are publicly available. The first phase will utilize extant data. To attain traditional college completion rates, the National Center for Education Statistics has data sets available for download that can be customized. Since MOOCs are available internationally, the most appropriate data set for this particular quantitative research would include college completion rates by country as a starting point. Additionally, an overall average can be extracted from this data. This would give us the average completion rate for traditional colleges. The next step would be to gather data for MOOC completion rates. Using internet searches there is information available at Class Central. Class Central has complied completion data for all courses offered by Coursera, EdX, and Udacity, which a re the three main platforms for MOOCs. The enrollment and completion data for each course have been recorded. Completion is defined by finishing all the requirements necessary for a certificate. Other data, such as course length, institution ranking, and active users, are also recorded on these data sets. This data set includes courses over the span of eighteen months. This information will assist in answering the primary research question: how do MOOC completion rates varyShow MoreRelatedA New Routing Mechanism For Manet Communication Essay1348 Words   |  6 Pagesknown as Hybrid Defending against Collaborative Black hole Attacks Gray Hole Attacks.

Factors Influencing Organizational Behavior And The...

Factor Influencing Organizational Behavior Student Name Course Name Course Code Introduction The study of human behavior in organizational settings, the interface between human behavior and the organization and the organization itself is known as Organizational Behavior. The study of organizational behavior can be divided into three levels: †¢ Micro Level – Individuals in an organization †¢ Meso Level – Work Groups †¢ Macro Level – How organizations behave It was observed by Chester Bernard that each individual behaves differently when acting in organizational role. Along with this there are many factors and attributes that influence the Organization Behavior. In this paper further, we will discuss few of these factors and attributes in detail. Leadership Theory and Organizational Behavior Leadership is one of the most important aspects in the organizational behavior. Barry Armandi (2003), explained in his journal with the case analysis that there is need of developing a foundation for completing the gap between leadership theory and practice.

Reading Visual Culture free essay sample

When reading visual culture one can easily be led to interpret from images . Visual representations have many different meanings, the way that some interpreted Visual culture and visual representations can in a way influence, confuse or inform others of their meanings. Visual culture is found almost anywhere in the world, no one really knows when it dates back to as there is so much visual culture in history. There are many examples of visual culture in different times, churches use to use visual culture in their stained glass windows. These windows use to be quite delicate pieces of art and were once considered highly religious, this was because of what was placed inside the windows and where they were most likely to be found was in churches. This was a ‘visual’ as it was able to be seen, but in many ways what was seen may not be real. For instance many of these church windows had angles on them and this made them in a way a fantasy or non-realistic character to some. We will write a custom essay sample on Reading Visual Culture or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The ‘culture’ of these windows was the people who viewed these on a religious basis, in other words the ones who shared the same values about the church that the windows were found in. Although there could be some confusion when discussing visible things and visual culture. Visible things are something like a chair, whereas visual culture would be a picture of the chair. The confusion normally lies in the word visible and visual, visualising something can be done when you see a poster and all the different pictures and writing that make up that poster. The format of a visual and how it is represented can impact others in different ways. If you see a sign that is red and says stop, your brain tells you that you need to stop only because this is what it has learnt to do in some cultures. Although in another culture where the word stop is just a heap of wiggly lines and means nothing they may see the red as danger and be cautious about their actions. Another example is when you read hieroglyphics, all most that do not understand them see are images of birds and leaves, whereas the people who know the writing see them as letters and words, it is how things are represented in the mind of others or one’s self. One of the basic units in visual culture can be signs, they can be icons and symbols, and are comprised of different codes. One thing can mean another and then could lead to a serious of different events. Signs that are a well-known icon are something like Coca-Cola. Coca-Cola is a worldwide known product, it is iconic to those who see it. There are many different ways people think of Coke, one of which is the writing on the bottle and the red label that coincides with the label on the bottle. Signs are comprised of different codes, in saying this they are all in their own way a code. In the war a code was considers a bunch or mumbled up words that made no sense, it only made sense to those who understood them. This is much like signs, only those who understand the signs can read them. Referring back to the stop sign as they are symbolic codes, whereas posters are iconic codes, the reasoning for this is because one symbolises an action whilst the other is an iconic image that is there to be seen and viewed so it may draw those who view it in. Although symbolic signs and iconic signs may seem very different they can sometimes be the same.

Lady Butler Balaclava (1876) Essay Example

Lady Butler: Balaclava (1876) Essay Lady Butler:Balaclava( 1876 ) Elizabeth Thompson ( subsequently known as Lady Butler ) was commissioned in 1876 by Queen Victoria to paint a image marking the gallantry of the British soldiers at the Battle of Balaclava. The Battle of Balaclava was an of import conflict of the Crimean War ( 1854-1856 ) – a struggle between Britain and Russia over district and natural resources in the Caucasus. The Battle of Balaclava ( 25 October, 1854 ) was celebrated at the clip ( and since ) for the ‘Charge of the Light Brigade’ when the British Cavalry was sent on a suicide mission against the heavy weapon and guns of the Russian military personnel with the inevitable consequence of mass human deaths on the British side ( in the terminal, six hundred and sixty one troopers were reduced to one hundred and ninety five in a affair of a mere 20 proceedingss ) .

This meant that the creative person was, in footings of infinite and clip, divorced from the capable affair, which gave her the ability to concentrate on demoing the humanity of the returning, demoralised British military personnels as opposed to painting a image of military glorification as would about surely have been the instance had the troubling been commissioned instantly after the event. Harmonizing to Hichberger ( 1990 ) , this is typical of the ulterior Victorian attitudes towards military picture where a discernable sense of feminism and sensitiveness is prevailing in the word picture of war on canvass. This development besides signalled a more realistic attack to the portraiture of warfare in British military picture, which is in pronounced contrast to military art of a century beforehand during the Napoleonic Era when war was shown to be a glorious exercisin g and the soldiers were seen as heroes instead than victims as is clearly the instance in Lady Butler’s Balaclava. This open sense of artistic pragmatism is aided and abetted by the manner in which the creative person focuses on the rank and file of the British Cavalry as opposed to the officers and leaders of the military. Again, this shows a important leap forward from military picture commissioned at the beginning of the 19th century when art tended to concentrate entirely on the military elite such as Wellington at Waterloo. The speech pattern upon pragmatism and upon concentrating on the rank and file of the armed forces who were sent into a apparently unpointed charge during the Crimean War serves to greatly change the temper of the picture. Its consequence upon the screening audience is greatly enhanced because if the manner in which it speaks of the soundless heroes of the British Army and, moreover, non merely in the context of the Battle of Balaclava. Rather, Lady Butler’s picture can be seen to be talking on behalf of all the rank and file of soldiers who had fallen in the name of the British Empire during the Victorian Era: those work forces who had laid the foundations for the glorification and domination of Britain on the universe phase that became progressively evident towards the latter portion of the 19th century. This sense of range is enhanced by the graduated table and the format of the oil on canvass picture by Lady Butler whereby the sheer size of the graphics can be seen to mirr or the sheer size of the Empire and the sheer graduated table of the human agony that went into its sophistication. Balaclava is hence a aglow illustration of a Victorian ‘academic’ picture where the creative person does non so much seek to do a point or to province an statement as opposed to inquire farther inquiries as to the intent of war. â€Å"The image is a authoritative illustration of late 19th century academic picture: the canvas is big and features many figures assembled in a assortment of airss and word pictures ; each figure was painted from life harmonizing to the traditional canon of anatomy.† ( Lalumia, 1983:9 ) In this sense, Balaclava can be interpreted as a unquestionably ‘English’ picture for its clip, particularly within the broader context of the formation of Victorian values. The Victorians, more than any other historical peoples, were obsessed with the duplicate issues of morality and decease ( Stevens Curl, 2004 ) and these concerns can clearly and identifiably be seen to attest themselves in Lady Butler’s pictures. Morality is expressed through the desolate faces of the soldiers returning from the doomed charge, which begs the inquiry as to the point of this war. The compulsion with decease can be seen in all of her military pictures including Roll Call and Return from Inkerman where the dead are depicted side by side with the life. This accordingly makes Lady Butler a discernibly English creative person who displayed a unquestionably Victorian position of life, morality and finally decease. However, although Lady Butler can be placed within the broader context of ‘Englishness’ and Victorian Values refering to art and life, she was of class a alone person who stamped her ain authorization and manner on her originative end product. The fact that she was a adult female ( and a immature adult female – she was boulder clay in her mid-twentiess in 1876 ) clearly set her aside as an person as did her pick of capable affair – military art. For this ground, she has attracted her ain biographers, such as Peter Usherwood and Jenny Spencer?Smith ( 1987 ) who dedicated their book to her conflict art. Balaclava and other pictures by Lady Butler are besides featured in more general art history books, such as Michael Paris’ Warrior Nation ( 2000 ) which shows how war in all its signifiers was a cardinal characteristic of British national civilization during the 19th and 20th centuries. In this manner, Lady Butler’s work lives on in the present t wenty-four hours and retains relevancy for everyone who wishes to understand the consequence of war on the British national mind as viewed through the lens modern art history.

Solitude essays

Solitude essays In the essay  gSolitude, h the author Henry David Thoreau says that nature is the place where he can feel harmonious with and loved by nature, and cannot feel solitude. In addition, there is enough time that he can spend contemplating a society. First, he had also felt fear or solitude in a deep woods as many people think. However, he found he was not alone, rather, he was surrounded by gentle nature. So, he says he loves a long rain storm, because he can be alone and be healed by the sound of rain. Then, he implied that he did not like a society, because, to live in a society, we had to be restricted by many rules to let us stand or endure  gfrequent meeting h. In the situation, we are apt to forget to respect with each other, and he suggested that we should live in nature. If we do so, we could notice significance of the respect and be able to restore  ghearty communications. h In my childhood, my father would often take me to a camp in weekend. The campsite was located in a forest, but not deep or secluded, and my father and I go fishing at a lake near to the campsite in early morning. There was no people around us, so after we came to the fishing point and my father turned off the engine of a boat, we could not hear anything. Little by little, I became able to hear the sound of wind in a heavy fog, and I could feel restful and comfortable, liberated from society. Exactly, I believe his idea might be fine or nice. If everyone could feel the same thing or feeling and notice the value of nature, we would have a leeway to think about everything. And we could live better than now, and we would think about nature more seriously. In addition, we could avoid a tragedy as in  gFriends, h which was caused in modern, crammed, lonely society. ...

Curating the Web

Curating the Web Curating the Web Curating the Web By Maeve Maddox A Doonsbury strip in the Sunday paper introduced me to a new expression: curating a brand. Until then, the only meaning I knew for curator was â€Å"a person who looks after a museum collection.† I don’t know if Rohit Bhargava coined the term, but his article â€Å"Manifesto For The Content Curator: The Next Big Social Media Job Of The Future?† explains what is meant by content curator and what it means to curate the web: A Content Curator is someone who continually finds, groups, organizes and shares the best and most relevant content on a specific issue online. According to Rohit, â€Å"experts predict that content on the web will double every 72 hours.† He says that businesses that want to keep up with consumer comments on their products will require a full-time content curator. A related term is CGM: Consumer-Generated Media. The identity of the person who coined this term is known: Pete Blackshaw, CMO (Chief Marketing Officer) for Nielsen Buzzmetrics. In the old days, CGM consisted of letters and phone calls that were easy to ignore. Now it embraces blogs, photos and videos. Thanks to social networking sites, a positive or negative comment on a restaurant, a movie or a brand of cereal can go viral in minutes. This kind of CGM cannot be ignored. A site called Brandeo gives this definition of a CGM Multiplier: The extent to which an offline event (ad campaign, launch, new CEO) stimulates online discussion. Brandeo itself seems to be a web curator for the marketing industry. Manufacturers and service providers are not the only entities being urged to think about curating the web. The site Publishing 2.0 offers an article directed at journalists. Best Practices for Journalists Curating the Web The same site has an article by Scott Karp that suggests that instead of laying off redundant wire editors and feature editors, print newspapers might retrain them as web curators. On one site I found the term co-curate: How does a museum, with a (presumably) carefully constructed brand, often based largely on its carefully curated collection (whatever that may be), invite its patrons to co-curate that brand? Is that even a desirable goal? Does it depend on the museum, or the type of museum? BethDunn I came across the term curator effect at a site called CuratorEffect: The Curator Effect explains how profound shifts in consumer expectations mandate new business rules in eliciting consumer trust. An example of curating the web can be found on the NY Times technology page: a round-up feature called What Were Reading in the lower right sidebar.

Comparison of Three Sculptures Essay Example | Topics and Well Written Essays - 250 words

Comparison of Three Sculptures - Essay Example Michelangelo’s interpretation however shows David before his battle with Goliath. He carries his slingshot over his shoulder and is almost unnoticed. The expression on his face shows he is ready for battle. On the other hand, Donatello depicts David after his triumphant battle with Goliath. He is shown stepping over the head of Goliath. The masculinity of David is emphasized more in Bernini’s and Michelangelo’s sculpture as opposed to Donatello’s. Bernini’s sculpture clearly shows the force and energy exerted by David as he launches the stone. The muscles in his legs give the impression of how his feet hold tightly on the ground to support the strain in his body’s stance. David’s skillful maneuver of his sling was perfectly interpreted by Bernini. One also observes the anger shown through David’s facial expression. Michelangelo’s sculpture of David shows a more relaxed David in contrast to Bernini’s. The contours of David’s physique seem flawless. Michelangelo sculpted David’s body with preciseness, molding with perfection his bones, muscles and veins. As opposed to Bernini’s and Michelangelo’s interpretation of David, Donatello portrayed David in a very fragile physique, almost like a woman. It lacks masculinity, as if David was only in his teens. It does not seem to be a body of a well-developed man. Even the stance of David which presents him with his left arm on his waist is so unbecoming of a fighter, which is very unlike Bernini’s and Michelangelo’s image of David. The saving grace of the masculinity of Donatello’s David is the lower part of the sculpture which shows David stepping over the head of Goliath. All three sculptures show how the interpretation of a subject can vary depending on the artist. The views, beliefs and backgrounds of the artists have an effect on their masterpieces. A single subject such as David can be interpreted in a number of ways depending on who is creating

Dream Worlds Essay Example for Free

Dream Worlds Essay So much has changed in how gender relations are carried out in today’s society. In past societies, much attention was paid to hierarchical relations. The women in the days of yore were only given a certain set of rights and privileges that were determined by men. Over the years, however, there has been a so-called â€Å"emancipation† of women. Beginning with the right to suffrage, women were gradually given increasing rights and participation in present day society. The influence that women have in today’s world is such that it can even be argued that they might even have the upper-hand gender wise. As Dream Worlds II reveals, one of the tools that women have used to regain their dominance over men is their sexuality. As the proverbial gate-keepers for sexual satisfaction, women are able to use their sexuality, seemingly at will, to gain whatever they want in society. While it seems that it is the men who are inducing these women to use their sexuality for material favors or otherwise, a close inspection will reveal that it is the result of a conscious decision of society. By engaging in a more capitalist mentality, the relation between the sexes is no longer about gender but rather accumulation of material wealth. The struggles that emerge between the sexes in today’s society are more concerned with gaining the upper-hand in a material aspect and everything, even sexuality, can be used as a tool in all of this. Given this situation, it would be incorrect to cite that it is subservience to men but rather it is the realization that such a facade is necessary to gain an upper-hand. There is no clear cut solution to this problem. In fact, it can be likened to supply and demand. There is a supply of women that meets a certain demand but in order to take advantage of this there must be an equivalent or greater exchange. It is more of a function of society than it is a battle of the sexes. A mutual agreement that this relationship is ideal in today’s situation.

Brecht and Dudow Essay -- Film Analysis

Kuhle Wampe (Brecht and Dudow, 1931) is often noted as the first communist film produced in Weimar Germany and was produced by a collective of men, heavily involved in the formation and success of Weimar cinema. The collaborative team consisted of Hanns Eisler, who composed the musical score for Berlin: Symphony of a Great City (Walter Ruttmann, 1927), Ernst Ottwald, a distinguished novelist and screen writer, primary director Slatan Dudow who participated heavily in the production of Metropolis (Fritz Lang, 1927) and finally Bertolt Brecht. The aforementioned trio heavily influenced the industrialised surrounding that encompass’ the location and narrative of Kuhle Wampe, however, fellow script writer and co-director Bertolt Brecht had very little experience in film production –aside from aiding the preparation for Karl Valentin’s The Mysteries of a Hairdresser’s Shop (1923). Brecht’s influence upon Kuhle Wampe came much more in the form of philosop hical grounding, with himself, at the time developing his ‘materialist aesthetics’ in trying to conceptualise the answer to the question: ‘what is political art?’ Bringing together politics and art formulae, in this case montage, we can assess the messages that were conveyed through the use of montage and how it was used as a tool of political suggestion. From the opening sequence, Kuhle Wampe’s stylisation appropriates itself with that of Soviet Montage, of which is Sergei Eisenstein’s theories are based on the idea that montage originates in the "collision" between different shots in an illustration of the idea of thesis and antithesis.

Malampaya Project

THE MALAMPAYA PROJECT The Malampaya project is a one of its kind project that the Philippines have developed. It is a big opportunity for the Philippines in gas development. The project aims to harvest Gas deep underwater and to use it as a source of power. It provides at least 40-45% of Luzon’s electricity since 2002. It is currently being conducted by Shell Philippines Exploration together with the joint partners Chevron Texaco Malampaya and PNOCEC. The gas was buried approximately 800 meters underwater deep in Northwest Palawan.According to Department of Energy Philippines (2002) that Malaya Gas field is to produce 146 billion cubic feet (BCF) a year. It was proven that they have at least 80 million barrels of condensate and 20-40 million barrels of oil reserves which totals 2. 5 to 3. 5 trillion cubic feet of Gas (TCF). Last December 2012 there has been a plan to expand the Malampaya Gas plant. The Keppel Subic Shipyard started â€Å"striking steel† or steel cutting as a signal for their $1 billion fabrication of an offshore rig in expansion of the Malampaya project.Keppel Subic will be a great help in developing the Malampaya project by building and installing substructure and topside modules in platforms to sustain its 2,700 megawatts production output and for the completion of the Malampaya 3. Also, it will generate at least 1,200 jobs according to Shell Philippines. It has been planned that in 2014, they will build additional two wells and in 2015, installing of new platform for additional equipment and facilities.According to the consortium, the Malampaya 3 aims to keep a steady supply to maintain their commitments in ensuring the power supply for Luzon. It has been proven that they have 3. 2 trillion cubic feet reserves and 1 trillion of it has already been consumed.

A Literary Analysis of Still Alice Essay

Still Alice (Genova, 2009) is a captivating debut novel about a 50-year-old woman’s sudden decline into early onset Alzheimer’s disease. The book is written by first time author Lisa Genova, who holds a PH.D in neuroscience from Harvard University. She’s also an online columnist for the national Alzheimer’s association. Her other books include Left Neglected and Love Anthony. She lives with her husband and two children in Cape Cod. The theme of the book is related to the early onset Alzheimer’s disease and how the main character, Alice Howland’s quality of life or in other words her lifestyle is affected due to the disease she is diagnosed with (Genova, 2009). The novel sheds light on the lives of those struggling with this horrendous disease of the mind and how their lives and people in them are affected and disturbed because of it. The life and daily activities of an early on-set Alzheimer’s disease patient worsens with time, if prop er counseling sessions and treatment are not conducted; their situation will get worse and result in severe damage to their mental health. As the story begins, everyday quarrels reside in the Howland household. From their youngest daughter Lydia’s ongoing dispute about her future, to Alice and John’s own relationship, all while their busy lives ensue. Why couldn’t Lydia be like the rest of her family? Her brother Tom and sister Anna followed in their parent’s footsteps. Going to college and having successful careers was their way of life. John is a biologist and Alice a professor of linguistics, both of them work at Harvard University. Lydia is the outcast of the family. She travels the world, is worry free, and aspires to be an actress. The hectic lives of both Alice and John weigh on their relationship. Tension increases with the story as Alice is diagnosed with early onset Alzheimer’s disease. The coping skills of Alice and her family with her diagnosis set the tone for the story. Alice’s internal conflict consumes her, although she tries to never let Alzheimer’s disease define her. She is upset with herself for forgetting things, yet trie s to come up with reasons as to why she is forgetting. Her father takes the brunt of all Alice’s anger. Her hatred for him grows. Why did he have to take the lives of her mother and sister? Is it his fault Alice has Alzheimer’s? Alice continues with a strong desire to contribute to society. The once estranged relationship between Alice and her daughter Lydia gradually improves, and a  daughter finds solace in a mother she never knew. A husband, who at one time stood by his wife through everything, surprises his family and leaves his ailing wife behind for a new job opportunity. Still Alice is told in the third person point of view with limited omniscience. The narrator is Alice Howland, the main character of the story. Through the book we are able to read the way Alice is feeling, looking through her eyes as the story unfolds. However, in the final chapter of this novel the point of view changes to her husband, John Howland. Readers are able to look on as John lives his life away from Alice in New York. The primary settin g for still Alice (Genova, 2009) is in Cambridge Massachusetts were the main character Dr. Alice Howland lives with her husband, John Howland, and teaches cognitive psychology at Harvard University. Other settings include their home in Chatham Massachusetts where Alice and John go to vacation. The main character is Dr. Alice Howland a modern middle aged professional woman. She’s a brilliant professor experiencing mental glitches like forgetting a word while giving a lecture, misplacing keys, etc. Alice thinks this is due to impending menopause, middle age or possibly stress. But she hasn’t gone through menopause and she’s not feeling stressed. The defining moment is when Alice forgets her way home while jogging in Harvard square (p. 21). Suspecting that something is wrong and without telling her husband, Alice chooses to see Dr. Davis a neurologist who diagnoses her with early onset Alzheimer’s disease (p. 70). The diagnosis hits Alice and her family like a death sentence. Alice realizes that she doesn’t have enough time left and decides that it should be spent with her family. Her two older children Anna and Tom decide to undergo genetic testing for the Alzheimer’s gene. Her oldest daughter Anna tests positive for the gene (p. 108). Alice becomes completely reliant on her blackberry to get through her day and becomes a great list maker though she can’t always make sense of her lists. As the disease progresses Alice resigns her teaching position at Harvard University and gives up jogging because she has lost her sense of depth perception. Although the disease robs Alice of her memories, she retains her sense of humor e.g. when she tries to wear her underwear as a sports bra, â€Å"she laughs at her own absurd madness† (P. 199). Alice’s character is very compelling, engaging, and holds your attention throughout the book. John Howland is Alice’s husband; he is a professor of biochemistry at Harvard University.  When John finds out about Alice’s diagnosis, he thinks that she has been misdiagnosed. He insists on genetic testing, which would show that Alice has the Alzheimer’s gene. John struggles to deal with Alice’s diagnosis. He becomes her primary caretaker, but refuses to look at Alice when she takes out her pill box. He manages to continue working by leaving Alice large reminder notes on the refrigerator not to go running alone (p. 196). John is obviously grieving the loss of his wife but is unable to express his emotions in a positive way. A breakthrough finally happens when John is able to comfort his wife when she experiences an incontinence episode (p. 150). Anna is Alice’s oldest daughter; she’s a successful lawyer and is married to Charles, also a lawyer. Anna is strong and fiercely independent just like her mother. Anna deals with her mother’s disease by suggesting that if her mom â€Å"thinks for a second† then maybe she’ll be able to remember things (p. 173). Anna, however still makes time to care for her mom when her dad is away. Alice’s only son Tom is a minor character in the book. He is present during family gatherings and important moments e.g. when Alice discloses that she has Alzheimer’s disease (p. 103). He deals with his mom‘s diagnosis by being distant. The main antagonist in the book is Alice’s youngest daughter Lydia Howland. She defies the family’s educational tradition and chooses to take acting classes in Los Angeles in hopes of becoming an actor. Lydia’s decision causes a lot of conflict between her parents. She’s the only one that refuses to participate in the Alzheimer’s genetic testing. However, as Alice’s condition deteriorates, Lydia becomes the most valuable player of the family; she becomes Alice’s number one advocate. She doesn’t try to â€Å"test† Alice’s memory but is there for her when she needs her (p. 162). The relationship between Alice and Lydia improves. Lydia eventually listens to her mother’s advice and enrolls at Brandies University to study theater (p. 258). The imagery in Still Alice is captivating. It keeps the reader on their toes, wondering what will happen next in the story. The story is so moving that the reader can essentially picture the characters and endure their experiences through all five senses. One model of imagery that is intriguing is when Alice is a guest speaker at Stanford. Her confidence and love for her career is enticing. She had talked about the particular subject numerous times and every time she had done this, she felt respected. Alice had always talked without reading her  notes with ease. Well into her discussion she suddenly becomes puzzled. â€Å"The data reveal that irregular verbs require access to the mental†¦Ã¢â‚¬  (p. 10). The word was lost even though she understood fully what she had intended to say. As the scene is described, the reader can get a sense of panic that Alice is experiencing (pp. 8-11). An unforgettable illustration of imagery is when Alice goes for a run through Harvard Square, blocks from her home and cannot remember her way back. The description of her surroundings is etched in the reader’s mind. â€Å"Steady stream of joggers, dogs and their owners, walkers, rollerbladers, cyclists, and women pushing babies in jogger strollers, like an experienced driver on a regularly traveled stretch of road† (pp. 20-21). â€Å"The sounds of her Nikes hitting t he pavement in syncopated rhythm with the pace of her breath† (p. 20). â€Å"She knew she was in Harvard Square, but she didn’t know which way was home† (p.21). â€Å"People, cars, buses, and all kinds of unbearable noise rushed and wove past her† (p. 22). The reader can sense Alice’s state of fright during this scene. A memorable instance of imagery is when Alice visits her primary care physician. At one point and time Dr. Moyer’s office held no negative links for Alice. â€Å"I don’t think your memory problems are due to menopause† (p.41). â€Å"She fought the impulses growing louder inside her, begging her to either lie down or get the hell out of that examining room immediately.† The reader can perceive the state of anxiety Alice is in (p.41). Other doctor visits were just as interesting. â€Å"Alzheimer’s disease†¦.The words knocked the wind out of her†¦The sound of her name penetrated her every cell and seemed to scatter her molecules beyond the boundaries of her own skin† (pp. 70-71). The visit to Mount Auburn Manor Nursing Center was striking. â€Å"Walkers crowded the spaces between the tables†¦There was no socializing, no conversation†¦The only sounds other than eating came from a woman who sang while she ate† (p. 113). The reader gets the impression that Alice feels she doesn’t belong there. Another prominent illustration of imagery is when Alice gets lost in her own home. â€Å"She hastened back down the hall and opened the door to the bathroom†¦Only, to her utter disbelief it wasn’t the bathroom† (p. 149). The reader understands that Alice’s disease is progressing, especially when she doesn’t recognize her own daughter or her own family. â€Å"Leave me alone! Get out of my house! I hate you! I don’t want you here† (p. 211). Alice couldn’t understand that it was her family having a dispute about her, nor did she understand why. â€Å"She  wasn’t sad or angry or defeated or scared†¦she was hungry† (p. 264). The most remarkable moment in the novel that captures the audience is when Carole returns Alice to her home after their walk. As Carole and Anna converse about Alice, Alice smiles and nods her head as to concur, not knowing that they are speaking of her. Shortly after, Lydia and Anna converse about their father coming to visit. â€Å"Is Dad coming this weekend? asked the act ress† (p. 291) The reader comprehends that John has decided to take the new job offer, instead of fulfilling Alice’s wish for them to stay together. There are many symbols within the story of Alice Howland: objects, actions, or characters that hint a meaning beyond themselves. Clocks play a role throughout the entire book. For Alice clocks are guidelines to what she should be doing at each moment of the day. In the start of her story, the clocks are more of a reference, but as her disease progresses they are much more than that. Alice becomes dependent on the clocks to tell her the things she is supposed to do according to time. Alice’s Blackberry device is probably one of the most significant symbols in Still Alice. The Blackberry becomes a part of her as Alzheimer’s takes over; Alice refers to her Blackberry for everything. To Alice, if something was not recorded in her device, it never existed. Within the Blackberry, she had an alert asking her five questions every day. These five questions became a reflection of her cognitive level, testing herself to see if her disease has progressed. The questions she quizzes herself include a P.S. â€Å"if you have trouble answering any of these, go to the file named â€Å"Butterfly† on your computer and follow the instructions there immediately† (p.119). The file named â€Å"Butterfly† signifies dignity to Alice; the file instructs her to commit suicide when she can no longer remember her family. This would have become the last thing she could do for herself. Alice also has a butterfly necklace that had been passed down from her mother. This butterfly necklace seems to calm Alice and to give her hope, clarity, and strength. Genova’s use of figures of speech brings the reader into the world of a person with Alzheimer’s disease. When Alice first suspects that there is something wrong with her, she is referred to a specialist for testing. Having completed various tests, Alice begins to feel overwhelmed, comparing her thoughts to a roller coaster that she was riding with her eyes shut, unable to know when the next turn would be (p.40). Later, in the same doctor’s office, Alice learns of her official  diagnosis of early-onset Alzheimer’s disease and is stunned. With the use of language, Alice and the r eader are brought back to the harsh reality of losing herself. â€Å"The sound of her name penetrated her every cell and seemed to scatter her molecules beyond the boundaries of her own skin (p.71). Genova relates Alzheimer’s disease to a beast that is unable to be slayed, giving the reader the knowledge that this disease cannot be beat. In reference to the medications Alice is taking to try to prevent the further decline in her mental state she compares them to aiming squirt guns at a blazing fire (p. 117). Throughout the book, Alice feels embarrassed and like a burden to those around her. The use of personification of her disease tells the reader exactly how embarrassed she is â€Å"there it was, her Alzheimer’s, stripped and naked under the fluorescent lighting† (p.129). It is further conveyed to the reader when Alice thinks her husband looks at her the same way he looks at his labs rats (p. 135). In a later scene when Alice refuses to go to dinner with friends the use of simile brings the disease to colorful life in Alice’s world. â€Å"I’m a cotton candy pink elephant in the room. I make everyone uncomfortable. I turn dinner into a crazy circus act, everyone juggling their nervous pity and forced smiles with their cocktail glasses, forks, and knives† (p.218). To keep the book from not being completely negative, there is humor to Alice’s Alzheimer’s symptoms. When she was unable to recall which door in her house lead to the bathroom, Genova’s use of humor is exactly what the reader needs to get through the scenes. â€Å"She swung the door open like an illusionist revealing her most mystifying trick, but the bathroom didn’t magically appear† (p.150). Nearing the end of the novel, Genova leaves the reader with one last insight into Alice’s cognitive decline. In a moment of clarity Alice reads the cover of the book she wrote with her husband â€Å"The words she read seemed to push past the choking weeds and sludge in her mind to a place that was pristine and still intact, hanging on† (p. 284). The story of Sti ll Alice is based on an ironic situation. Dr. Alice Howland is a psychology professor at Harvard University and an expert in linguistics (the study of language and its structure). She finds herself at a crossroads when she is diagnosed with Early Onset Alzheimer’s Disease at the age of fifty. Dr. Howland also keeps remarkable care of her well-being by eating healthy, running Harvard square each day, keeping her mind active between teaching classes, and attending  conferences. While talking over her new diagnosis Alice comes to realize she may have misjudged her father, assuming he was a belligerent alcoholic, in reality she realizes he was likely suffering from undiagnosed Alzheimer’s disease (p.76). To top off the ironic chain of events Alice receives her diagnosis of Early Onset Alzheimer’s on January 19 (p. 67) which happens to be the date of her mother and sister’s deaths. Towards the end of Alice Howland’s story, her disease process has taken its toll on Alice’s mind and she c an no longer care for herself independently. Dr. Howland becomes dependent on her daughters and son, whom she can no longer identify as such, for her care while her husband choses to take a job in New York (p.286-292). In conclusion, Still Alice is the story of a happily married professor with three grown children at the peak of her career who is diagnosed with early onset Alzheimer’s disease. As the story unravels, Alice struggles to maintain her lifestyle, independence, and to live in the moment. The book not only brings to light the devastating effects of Alzheimer’s disease on its victims, but also on the lives of their friends, families, and relationships. Tension increases within the story from the time Alice is diagnosed with early onset Alzheimer’s disease until her husband leaves. It was heartbreaking that Alice’s husband chose to abandon his beloved wife for a new job opportunity in another city. He failed to stay by her side as this disease robbed her of herself. Still Alice is a strong and engaging fiction work which brings truth to the average reader about the onset and the impact of Alzheimer’s. However, it fails to address those families who are not as equipped as the Howland’s to care for their loved ones at home, and are forced to institutionalize them. As Alice’s condition deteriorates, her children begin to worry about their futures, fight amongst themselves, and ultimately change their lives as a result of their mother’s disease. This story teaches the valuable lesson that no matter how strong relationship or family ties are, the failing health of a love one could have a devastating impact on everyone.

Nitrate Contamination of Groundwater Poses a Serio Essays

Nitrate Contamination of Groundwater Poses a Serio Essays Nitrate Contamination of Groundwater Poses a Serious Health Threat Nitrates contamination of the world's underground water supply poses as a potentially serious health hazard to the human inhabitants on earth. High nitrate levels found in well water has been proven to be the cause for numerous health conditions across the globe. If we intend to provide for the future survival of man, and life on planet earth, we must take action now to assure the quality of one of our most precious resources, our underground water supply. Ground water can be defined as the water stored in the open spaces within underground rocks and unconsolidated material (Monroe and Wicander 420). Ground water is one of the numerous parts that make up the hydrologic cycle. The primary source of water in underground aquifers is precipitation that infiltrates the ground and moves through the soil and pore spaces of rocks (Monroe and Wicander 420). There are also other sources that add water to the underground aquifer that include: water infiltrating from lakes and streams, recharge ponds, and wastewater treatment systems. As groundwater moves through the soil, sediment, and rocks, many of its impurities are filtered out. Take note, however, that some, not all, soils and rocks are good filters. Some are better than others and in some cases, serious pollutants are not removed from the water before it reaches the underground supply. Now that we have a good working definition of what groundwater is, and where it comes from, just how important is it? Groundwater makes up about 22% of the worlds supply of fresh water. Right now, groundwater accounts for 20% of all the water used annually in the United States. On a national average, a little more than 65% of the groundwater in the United States each year goes to irrigation, with industrial use second, and third is domestic use (Monroe and Wicander 420). Some states are more dependent on groundwater for drinking than others. Nebraska and the corn belt states rely on underground water for 85% of their drinking needs, and in Florida 90% of all drinking water comes from underground aquifers (Funk and Wagnall 2). People on the average in the United States require more than 50 gallons of water each day for personal and household uses. These include drinking, washing, preparing meals and removing waste. A bath in a bathtub uses approximately 25 gallons of water and a shower uses about l5 gallons per minute of water flow while the shower runs. Just to sustain human tissue requires about 2.5 quarts of water per day. Most people drink about a quart of water per day, getting the rest of the water they need from food content. Most of the foods we eat are comprised mostly of water: for example, eggs, are about 74% water, watermelon 92%, and a piece of lean meat about 70%. Most of the beverages we drink are also mostly comprised of water, like milk, coffee, tea and soft drinks. And the single largest consumer of water in the United States, is agriculture. In dry areas, farmers must irrigate their lands to grow crops. It is estimated that in the United States, more than 100 billion gallons of fresh water are used each day for the irrigation of croplands (Funk and Wagnall 2). Since agriculture is the leading user of our groundwater, perhaps it is fitting, that it is also the biggest contributor of contaminating nitrates that work into our water supply each year. Agriculture and livestock production account for 80% of all nitrogen added to the environment ( Terry, et al. 1996). Industrial fertilizers make up 53%, animal manure 27%, atmosphere 14%, and point source 6% (Puckett, 1994). Just how do these nitrates get from the field into our water supply? There are two primary reasons that nitrate contaminates reach our underground water supply and make it unsafe. Number one reason is farmer's bad habits of consistently over- fertilizing and applying too much nitrogen to the soil. In 1995 America's agricultural producers added 36 billion pounds of nitrogen into the environment, 23 billion pounds of supplemental industrial nitrogen, and 13 billion pounds of extra nitrogen in the form of animal manure. Twenty percent of this nitrogen was not used by the crops it was intended. This accounts for about 7-8 billion pounds of excess nitrogen remaining in the environment where much of it has eventually entered the reservoirs, rivers, and groundwater that supply us with our drinking water (NAS 1995). The number two reason these contaminants reach our groundwater supply runs parallel

Polonium Facts - Element 84 or Po

Polonium Facts - Element 84 or Po Polonium (Po or Element 84) is one of the radioactive elements discovered by Marie and Pierre Curie. This rare element has no stable isotopes. Its found in uranium ores and cigarette smoke and also occurs as a decay product of heavier elements. Although there arent many applications for the element, it is used to generate heat from radioactive decay for space probes. The element is used as a neutron and alpha source and in anti-static devices. Polonium has also been used as a poison to commit assassinations. Although the position of element 84 on the periodic table would lead to categorization as a metalloid, its properties are those of a true metal.

Physical Education - Essay Example From the discussion it is clear that these three dimensions determine a person’s Quality of Life. As a result, the health and medical care increasingly target physical education because of its strong correlation with physical health. A study by Marmot et al. posits that improved QoL correlates with reduced illnesses and other health issues, and it reduces costs in treatment of the ailments. As a result, including physical education in the curriculum is a productive way of implementing healthy lifestyle for these pupils.This study highlights that exercising helps a pupil develop both the understanding and knowledge of their body’s performance, and most of the times the students remain amazed by their body’s abilities. This development brings about endurance, which links to the Christian value whereby a pupil shows endurance when exploring his or her body’s capabilities. Creativity, expression of feelings and emotions come out right during dance and sports a mong other gymnastics. Students may build a positive mindset that promotes progression if allowed to have a reflection time to evaluate their experiences. In addition, these students will see a sense of admiration and respect when observing elite performance from professional athletes and their peers.  The physical education promotes healthy lifestyle and healthy living is vital for every student. During fair play, a student develops the ability to identify right from wrong in the sporting events, and especially during competition.

Using GIS Profiling to Solve Serial Burglaries Research Paper

Using GIS Profiling to Solve Serial Burglaries - Research Paper Example It then elaborates on GIS tool and its appropriateness in solving serial crime using geographic profiling. More significantly, the paper relates geographic profiling to solving serial burglaries. Serial crimes are illegal acts that warrant punishment based on criminal law. They are crime defined by repetitive nature. Serial crimes include murder, rape, arson, bombing, and robbery. Serial criminals frequently develop behaviors of committing the same type of crime in a similar manner. Sequence of crimes committed by the same lawbreaker constitutes serial crimes that law enforcement agencies files. Studies relate serial criminals to immoral upbringing or environment. Advancements in technology have contributed to increased serial crimes around the globe. Criminals are highly innovative and frequently adopt emerging technology advancements before criminal agencies acquire such technologies. Such innovative criminals have also acquired similar crime tracking devices used by law enforcement agencies. For instance, innovative criminals have encrypted radio communication networks of state agencies.’ Insecurity cases have increased around the globe because of innovativeness of criminals. Criminals have devised advanced systems of committing a crime and escaping from law enforcement agencies. For instance, Serial killers and terrorists use modern communication technologies such as satellite imagery, night vision goggles and smart phones in locating their targets and enemies. Evidence also exists of terrorists who have formed operations centers for monitoring social networks, videos, and global news broadcasts. Serial killers such as the 2008 Mumbai terrorists used modern weapons such as AK-47s, hand grenades, and explosives (Goodman, 2014, p. 1). The terrorists employed use of search engines in planning the attacks and in identifying specific hostages.

Externality Definition Essay Example for Free

Externality Definition Essay 1. An externality is defined as a benefit or cost that is imposed on a third party, such as society, other than the producer or consumer of a good or service, or, more simply, an economic side effect. The more of a product that is consumed or produced, the more of an externality that results. When discussing externalities in general terms, positive externalities refer to the benefits and negative externalities refer to the costs associated with the production or consumption of a good or service. Public goods are one of the more common examples of positive externalities. Public goods are goods which are difficult to exclude people from benefiting from or from getting a free ride. Public goods, such as national defence, clean water, clean air, law enforcement, etc., are generally good for most, if not all of society. Negative externalities exist in many situations. One of the most common examples is that of pollution. In these situations, the producer and consumer finance the goods produced but society must bear the cost of pollution that is introduced into the environment as a by-product and is thus a negative externality. Using the above mentioned example of negative externality, pollution, a steel producing firm might pump pollutants into the air. While the firm has to pay for electricity, materials, etc., the individuals living around the factory will pay for the pollution since it will cause them to have higher medical expenses, poorer quality of life, reduced aesthetic appeal of the air, etc. Thus the production of steel by the firm has a negative cost to the people surrounding the factory-a cost that the steel firm doesnt have to pay. 2. Negative externalities are a property rights problem. Who owns the air that the steel mill pollutes? Ronald Coase put forth the solution which is known as the Coase Theorem: Under perfect competition, once government has assigned clearly defined property rights in contested resources and as long as transactions costs are negligible, private parties that generate or are affected by externalities will negotiate voluntary agreements that lead to the socially optimal resource allocation and output mix regardless of how the property rights are assigned (Ronald H. Coase, The Problem of Social Cost, The Journal of Law and Economics, October 1960). In other words, if there are negligible transactions costs, as long as someone owns the rights to the air around the steel mill, the efficient outcome will prevail. For example, if the steel mill owns the rights, then the individuals that live around the mill will be willing to pay the steel mill not to produceup to the cost that they are incurring from health care, reduced aesthetic appeal of the air, etc. This amount that they are willing to pay becomes an opportunity cost for the steel mill if they produce. Thus they will cut production to the optimal level. On the other hand, if the people own the air, then the steel mill would have to pay them that same amount for the right to produce. Thus the negative externality is directly added to the steel mills marginal cost. 3. Based on experience, this theorem would not apply to the steel industry case discussed above. For example, with a steel factory that trespasses on the lungs of a large number of individuals with pollution, it is difficult if not impossible for any one person to negotiate with the producer, and there are large transaction costs. Hence the most common approach may be to regulate the firm (by imposing limits on the amount of pollution considered acceptable) while paying for the regulation and enforcement with taxes. This adds to the producers marginal cost and will cause them to reduce output.

Essay on China :: essays research papers

China is a geographical region in East Asia. It holds over one-fifth of the world’s population. Most of it is now known as the People’s Republic of China, but the name of the region refers to one of the world’s longest standing civilizations, which dates back almost 5,000 years. Because the length of China’s history, it has been characterized by repeated overthrowings and reestablishments of the government, and many civil wars. China was governed as an empire until 1912, when the Republic Of China, or the ROC, was established under Sun Yat-sen. China was the world’s technological leader for centuries, credited with the invention of paper, rockets, and other things. However, by the 19th and 20th centuries, China was losing political and economical power. Japan and the Western Powers were gaining influence, which eventually led to the evolution of the PRC, or the Peoples Republic of China. China has the world’s fastest growing economy, but it’s an unstable state underneath. It has the biggest rich/poor urban/rural divide, which means that the farmers are poor, and the people who have city jobs are rich. China is also hugely overpopulated, so as a population control method families can have only one child. Because of traditional honor, everybody wants male children instead of female ones so that they can carry on the family name. This has led to an imbalance between genders in China, so the government has established a program to compensate families for having female children. China has been working to reform its economy from a centrally planned economy to a market oriented economy. A centrally planned economy is where decisions about production, consumption, and allocation of goods is managed by a central power. This basically means that the government has complete control over what’s made, where it goes, how it’s made, and how it’s used.

Language Experience

1. Write about your past formal or informal language learning experiences. Would you consider them effective or ineffective? Learning foreign languages is a real challenge to everyone and a lot of people have their own successful and unsuccessful experiences. As for me, I’d like to tell about a negative one because, unfortunately, I had it more than positive. I’ve been learning English since I was 10 years old. At first, it was at school. Those lessons left much to be desired. We had a middle-aged teacher who used to have favourite students and showed her attitude, inhibitions cast aside. We didn’t have speaking tasks at all. She gave us different texts and we read, translated and learnt them by heart. Sometimes we even didn’t understand what we were speaking about which made it more difficult to answer. She didn’t use any communicative approaches. What is more, we weren’t interested and motivated. At the age of 15 I nearly decided to give up learning it. Needless to say, it was a real shock to everyone when I announced my decision to enter Pedagogical University, the department of foreign languages. I was sure that I would learn it there. I had a private teacher to prepare for entrance exams. At that time I thought she gave me a lot knowledge, but being a teacher now I can judge those lessons as a waste of time and money. Frankly speaking, it was self-studying. I was given 5 unites of grammar to do at home. Nobody explained any rules to me and we just checked exercises. Fortunately, at university I had a lot of different teachers. Some of them tried to use communicative tasks, such as role plays. But it was still academic studying. Teachers didn’t need to motivate us as we all wanted to pass exams and get a diploma. However ridiculous it may seem, I learnt English at work, being teacher is the best way to study. If I need to know something, I try to teach my students and after preparations for lessons and loads of explanations to them I get to know a lot. So joining TESOL course is another opportunity to learn the language and ways of teaching . 2. Why do you think the CLT has gained popularity in the language classroom? Our understanding of the processes of second language learning has changed considerably in the last 30 years and CLT is partly a response to these changes in understanding. Earlier views of language learning focused primary on the mastery of grammatical competence. Language learning was viewed as a process of mechanical formation. Good habits are formed by having students produce correct sentences. Errors were to be avoided through controlled opportunities for production. In recent years language learning has been viewed from a very different perspective. Communicative teaching emphasis on â€Å"task-oriented, student-centered† language teaching practice, asked to show the life of the actual needs of the English language to simulate a variety of life contexts, emotional, and to provide students with comprehensive use of English language, for communication of opportunities, its focus is not only a language in the form, grammatical accuracy, more emphasis on the appropriateness of language use, feasibility, communication skills, as well as training students in communicative activities in the strain and problem-solving ability. There are advantages and disadvantages of this approach. The pros are: – Language is acquired through communication – CLT allows learners to use the target language in meaningful context – CLT can be adapted to any level The cons are: -Student may not see the value in learning English through group work, games, and activities. – CLT does not focus on error correction. – Students don’t feel challenged Taking everything into consideration, I should say that the good thing about the communicative approach is that it makes students speak the language even at a beginner level and they are usually enthusiastic about this. . How would you approach a class with true and false beginners? I got used to having mixed-ability classes and the mixture of false beginners (they have had some English training at some point in the past) and true beginners ( these are learners who have had no contact with English at all) is a common situation. I consider such cl asses a real advantage as it helps to avoid boring lessons and I always have some students to rely on. I try to pair a true beginner with a false one while doing some activities and it helps to create an interaction between students which means a student-centred style of teaching. There are some drawbacks, of course. The false ones are faster to do exercises so I need to provide them with extra work which means more careful preparation for the lesson. Another problem is a demotivation of both kinds of students. There are some classroom management techniques which can help to avoid it. I should say it is a widely-spread situation but it can be successfully solved by using different methods of teaching.

Oryx & Crake Summary Essay

Xenotransplantation is the transplantation of living cells, tissues or organs from one species to another such as from pigs to humans ( Medical grafting). Such cells, tissues or organs are called xenografts or xenotransplants. The term allotransplantation refers to a same-species transplant. Human xenotransplantation offers a potential treatment for end-stage organ failure, a significant health problem in parts of the industrialized world and worldwide shortage of organs for clinical implantation. It also raises many novel medical, legal and ethical issues. A continuing concern is that pigs have different lifespans than humans and their tissues age at a different rate. Disease transmission (xenozoonosis) and permanent alteration to the genetic code of animals are a cause for concern. Genetic engineering, recombinant DNA technology, genetic modification/ manipulation (GM) and gene splicing are terms that are applied to the manipulation of genes. It involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually express a protein to reach desired effects. Cloning is the process of creating an identical copy of something. Genetic recombination is the process by which a strand of DNA is broken and then joined to the end of a different DNA molecule. A genetically modified organism (GMO) is an organism whose genetic material has been altered using the genetic engineering techniques generally known as recombinant DNA technology. Why Oryx and Crake Was Written â€Å"Every novel begins with a what if and then sets forth its axiom. The what if of Oryx and Crake is simply What if we continue down the road we’re already on? How slippery is the slope? What is our saving graces? Who’s got the will to stop us?† –Margaret Atwood Settings in Oryx and Crake Pre-Catastrophic Society: Games With Virtual Reality And Virtual Violence Society Fixated on Physical Perfection and Longevity, Virtual Elimination Of The Middle Class (produced a gap between rich and poor), Disappearance Of Safe Public Space, People Live In Either Tightly Controlled Compounds Of The Elites Or Dangerous Pleebands, Almost Everything Is For Sale, Medical Advancements, Life Is In The Hands Of Large Corporations, Private Security Forces, Scientific Advancements: Genetic Engineering & Xenotransplant, Technologically Driven, Extreme commercialization and commodification of life and the commodification of human life and sexuality in prostitution and online child pornography. Jimmy and Crake spend a lot of their free time playing online computer games such as Kwiktime Osama (a reference to Osama bin Laden) and Blood and Roses, or watching live executions, Noodie News, frog squashing, graphic surgery and child pornography. Post-Catastrophic Society: Naturalistic society Science vs. Anti-Science â€Å"Please don’t make the mistake of thinking that Oryx and Crake is anti-science. Science is a way of knowing, and a tool. Like all ways of knowing and tools, it can be turned to bad uses. And it can be bought and sold, and it often is. But it is not in itself bad. Like electricity, it’s neutral. The driving force in the world today is the human heart – that is, human emotions. (Yeats, Blake – every poet, come to think of it – has always told us that.) Our tools have become very powerful. Hate, not bombs, destroys cities. Desire, not bricks, rebuilds them.† –Margaret Atwood Plot Summary of Oryx and Crake The protagonist of Oryx and Crake is Snowman, clad only in a bed sheet and a Red Sox cap, who appears to be the last human being on Earth. He’s not entirely alone, however; strange hybrid beasts such as wolvogs, pigoons and rakunks are roaming freely. As well, a group of what he calls Crakers—strange human-like creatures—lives nearby. They bring Snowman food and consult him on matters that surpass their understanding; thus, Snowman comes across as a post-apocalyptic hermit guru. As the story develops, these assorted lifeforms are revealed to be the products of genetic engineering. In flashbacks, we learn that Snowman was once a young boy named Jimmy, who grew up in the early 21st century. His world was dominated by multinational corporations which kept their employees’ families in privileged compounds separated from a global lower moiety of pleeblands. Shortly after Jimmy’s family moved to the HelthWyzer corporate compound (where his father worked a s a genographer) Jimmy met and befriended Glenn (later known as Crake), a brilliant science student. Atwood’s satirical take on current society is presented most pointedly in the jaded activities of these two youths. Jimmy and Crake spend a lot of their free time playing online computer games such as Kwiktime Osama (a reference to Osama bin Laden) and Blood and Roses, or watching live executions, Noodie News, frog squashing, graphic surgery and child pornography. One of Glenn’s favourite pastimes is an online game called Extinctathon, a trivia game which requires immense knowledge of extinct animal and plant species. Using the codenames Thickney (Jimmy) and Crake (Glenn), they both play as teenagers. It is not until they are both in university that Jimmy discovers that Crake has worked his way up to become a Grandmaster. On another trip through the dark underbelly of the Web, they come across an Asian child pornography site, where Jimmy is struck and haunted by the eyes of a young girl. Unknown to Jimmy, Crake is similarly affected by the sig ht of this young girl. Crake eventually finds this girl (or a woman who could be her) and hires her, as both a prostitute and a teacher of the Crakers. Her name is Oryx. Jimmy identifies the haunting memory of the young girl with Oryx, though it is never made clear as to whether or not the two are the same person. Oryx eventually becomes intimately involved in the lives of Jimmy and Crake, and both fall in love with her. Oryx, however, views their relationship as strictly professional and only admires Crake as a scientist and â€Å"great man†. For fun and affection she turns to Jimmy, though her feelings for him are not as clear. The two hide their relationship from Crake, and Jimmy is often plagued with the thought of Crake finding out about his betrayal. Crake uses his prominent position at a biotech corporation to launch a project to create the Crakers. His goal is to create a peaceful society that will live harmoniously with each other and nature. These genetically engine ered humans are leaf-eating herbivores and they only have sexual intercourse during limited breeding seasons when they are polyandrous. Thus, many of the apparent conflicts in human culture are replaced with a mockery of intelligent design. At the same time, Crake creates a virulent genetic pandemic that, apparently, killed off all humans except for Jimmy. Jimmy was unknowingly vaccinated with the intention of acting as a guardian for the Crakers. Thus, Crake represents a mad scientist; he is maddened by the troubled society that he lives in. His rationale is that he is heroically saving intelligent life from an inevitably dying society. In the story’s climax, Crake’s perfected â€Å"hot bioform,† present in one of his company’s products, is activated and spreads throughout the world. When called to account for his actions by Jimmy, Crake kills Oryx by slitting her throat. In rage and panic, Jimmy shoots Crake, resulting in his being left to obsess over his vanished world and unanswered questions. Jimmy contemplates abandoning the Crakers but is constantly haunted by the voice of Oryx, and reminded of his promise to her to watch over them. Though Crake opposed and belittled human religion, Sn owman instills the Crakers with his own invented religion revolving around Crake and Oryx. Oryx becomes the guardian of the animals and Crake the creator god. Crake suffers from unremembered night terrors. During visits, Jimmy hears Crake screaming in his sleep. Crake claims to not remember them. This forms one of the book’s most profound ironies. Crake is a leader in the most advanced (and corrupt) health care system in human history, and Jimmy is unable to save humanity by simply getting Crake’s head examined. At the same time, however, Crake attends a university referred to as Asperger’s U, referring to the university’s high population of incredibly intelligent, socially awkward people, which might suggest that his idea was not the product of insanity or something ‘wrong’ with him, but rather the knowledge that everything else around him was wrong. During Snowman’s journey to scavenge supplies, he is uncomfortable wearing shoes now that his feet have become toughened without them. He cuts his foot on a tiny sliver of glass. Infected by who-knows-what descendant of transgenic experiments, his body cannot fight back, and his leg becomes inflamed.Returning to the Crakers, he learns that three ragged true humans have camped nearby. He follows the smoke from the fire and watches as they cook a rakunk. Uncertain of how he should approach them (Blast them to bits to protect the Crakers? Approach with open arms?) he checks his now unworking watch and thinks, â€Å"Time to go,† leaving the reader to speculate as to what his actions and future will be. Literay Works Coral Ann Howells argues that Oryx and Crake is in some ways a sequel to Atwood’s The Handmaid’s Tale in that it carries the national catastrophe in the earlier novel to global level[5]. A major reference seems to be to the â€Å"Last Man† topos in science fiction, which was inaugurated by Mary Shelley’s The Last Man, also a post-apocalyptic novel, whose main character is the only survivor of a plague that has killed off all other humans. George Orwell’s Nineteen Eighty-Four (1949) had a working title that relates it to Shelley’s book: â€Å"The Last Man in Europe†[6]. Other references, of course, include Shelley’s Frankenstein (1818/1831) as well as Jonathan Swift’s Gulliver’s Travels[7] (1626/1635). Gulliver’s Travels is also the source of one of the two epigraphs and puts emphasis on the claim that the speculation about the near future in Oryx and Crake serves to make a point about the present state of the world. Swift’s speaker as quoted by Atwood says: â€Å"my principal design was to inform you, and not to amuse you† (Oryx and Crake, Epigraph). The second quotation from Virginia Woolf’s To the Lighthouse (1927) refers to the absence of safety in the word, pointing to Snowman’s existence in the world af ter Crake’s catastrophe.

Evolving Experiment in Democracy essays

Evolving Experiment in Democracy essays Many historians have described the United States as an evolving experiment in democracy. This statement especially holds true during the time period of 1828-1844. During the time period of 1828-1844, under the rule of Jacksonian Democracy, several political, social, and economic changes occurred in the United States that clearly define the country as an evolving experiment in democracy. First of all, during the time period of 1828-1844 several political changes occurred that structured and expanded the government. Jackson set up a Spoils System, in which he gave his political supporters public office. Every man is as good as his neighbor, Jackson proclaimed. The aristocratic and bureaucratic officeholding class was eliminated. More ordinary citizens were involved in politics to give the ordinary citizen more say in the government. The Spoils System shaped the way the Democratic Party was organized. Slowly but surely the Democratic Party under the time period of 1828-1844 was organized to give more opportunities to the common person. Jacksonian ideas were incorporated in one manner by the elimination of property qualifications. By this elimination, any free white male could vote and hold office. As a result of the elimination of property qualifications came the redefining of the chosen class. Planters, urban workers, and factory laborers were included in the new cho sen class. The idea that the poorer citizen was just as important as a rich citizen came about. In addition, those united under Jacksons banner of democracy believed in more rights for the states. Eventually, a two-party system emerged, the Whigs and the Democrats. As a result of dislike for the American System and corrupt bargain under the rule of John Quincy Adams, Andrew Jackson united many people under a banner of democracy. The idea of public education for all citizens was promoted, which ...

Base properties of an antimicrobial agent Essays

Acid/ Base properties of an antimicrobial agent Essays Acid/ Base properties of an antimicrobial agent Essay Acid/ Base properties of an antimicrobial agent Essay Chem. 253 Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium beneath. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic PH. Rather than benzene acid, sodium beneath is used because it is generally soluble in most aqueous solutions but benzene acid is not. Reaction Sodium beneath mixed with water, dissociates into beneath and sodium ions. Hydrogen chloride, which is a gas, will exist in unionized form when combined with water to form hydrochloric acid. Then when the two solutions are combined, HUH+ transfers electrons to beneath ions, which act as the base to form benzene acid as a solid precipitate. The overall balanced equation is as follows. Yield Calculations: Sodium Beneath: Theoretical: The theoretical yield of Benzene Acid is 1. Egg. The actual yield of Benzene Acid is 1. Egg. The percent yield of this experiment is: Methods/Procedures 1) Weigh and tare a 50 ml beaker, then place about 1. G of sodium beneath into the beaker. Record the actual mass of sodium beneath used. 2) Measure about 10 ml of distilled water with a graduated cylinder and pour it into the beaker with the sodium beneath. Use a glass-stirring rod to dissolve the sodium beneath in the water. 3) Measure about 4 ml of 3. 0 M HCI and add it slowly, with stirring, to the sodium beneath solution until the pH of the solution is 2. Use pH paper to test the solution each time by using your stirring rod to place a drop of the solution on the pH paper. Adding excess HCI to the solution will not affect yield of product. 4) To induce crystallization of product, cool the solution to 10 degrees Celsius or below. Place your 50 ml beaker in a large beaker containing cracked ice with a little water to reduce the temperature. 5) Clamp a 250 ml filtering flask to a ring stand and place the Boucher funnel on top with an appropriately sized filter paper (be sure to pre-weigh the filter paper). Moisten the filter paper in the funnel with a little distilled water, and make sure that the moist filter paper fits snugly in the bottom of the Boucher funnel with no folds or bends in the filter paper visible. Use the thick rubber tubing from your drawer to provide vacuum from the aspirator to your filter flask. Be sure you are connecting the tubing to the aspirator, not to the water or gas outlet. Turn on the water to a low volume to create a vacuum in the filter flask but not so much that you flood the sink. Transfer the crystals (quantitatively) from Step 4 to the funnel. Use about 5 ml of distilled water to rinse any solid that remains in the beaker onto the filter paper. Let the solid air-dry with the aspirator running for a few minutes. 7) Place the filter paper with solid in the oven for about 15 minutes to dry. Weigh and then dry again for 5 minutes. Weigh again. If your second weight differs from the first weight by more than 0. 5%, dry again for 10 minutes. Continue this process until successive weighing are within 0. 5%. For this lab, we must be sure to always wear our safety glasses whenever we are in the laboratory and wear gloves when we are conducting an experiment. Benzene acid and sodium beneath used in this experiment can be mild irritants to the skin. We must be careful not to get them on Observations/Results The mixture began clear but once we added the HCI the substance was white and odorless. Our precipitate was solid and white. For the numbers, sodium beneath was the limiting reagent because it had 0. 01063 moles whereas hydrochloric acid had 0. 012 moles. The theoretical yield was 1. Egg and the actual yield was 1. 51 g. With these numbers the percent yield turned out to be 96. 37%. Discussion/Conclusion Throughout the experiment I felt as though there were some errors. Also, I feel as though I may have lost amounts of the mixture and precipitate through transfers that affected our final weight. I could tell that the pH had an effect because we know that if there is a decrease in pH a pr ecipitate starts to form. Exercises 1) In a solution containing aqueous sodium beneath, a decrease in pH usually results in the formation of a precipitate. A.
