Nick’s Psychological Development in Ernest Hemingway’s...

Nick’s Psychological Development in Ernest Hemingway’s In Our Time In Hemingway’s collection of short stories, In Our Time, we follow a character by the name of Nick Adams. We are introduced to Nick in â€Å"Indian Camp† as a young boy, and follow him to adulthood in both Parts I and II of â€Å"Big Two-Hearted River†. Through this we see Nick develop and learn about some major facts of life. Nick is a character who changes through the effects of war on many different levels. Although Hemingway hardly mentions the war, he uses the stories to express different effects and emotions caused by the war. In â€Å"Indian Camp† we meet Nick as he joins his father to help a pregnant Indian woman in labor. Nick’s father, a doctor, brings him to†¦show more content†¦Nicks father does not want to answer his wife’s questions, and when he does, he lies to her. He assumes that she will not understand his reasoning for the argument he just had outside. In addition, his wifes religious demands for him to not lose his temper show that she does not want him to be a stereotypical aggressive and protective male. Also, Christian Science religion does not believe in medicine, which means that she has no respect for her husband’s work. Nicks father decides to go hunting, where he can express his masculinity. When Nick decides to go with him, Nick is also showing an interest in male to male interaction over male to female interaction with his mother. We see Nick at the end of the story, still calling his father â€Å"daddy† and wanting to follow him arou nd. If the family would interact more, then it is probable that Nick would be able to develop more psychologically. He is still being treated like a little child, so he is still acting like one. We next see Nick and his reactions to relationships. In â€Å"The End of Something† Nick breaks up with his girlfriend Marjorie. He expresses to her that he is bored with his life and that they cannot stay together. This shows that due to Nick’s past, he is not ready for relationships with women. He does not want to live his life in the traditional manner that Marjorie expects him to. Due to his lack of development, he cannot communicateShow MoreRelatedIn Our Time Critical Analysis1578 Words   |  7 PagesNicks Psychological Development in Ernest Hemingways In Our Time In Hemingways collection of short stories, In Our Time, we follow a character by the name of Nick Adams.

Management Accounting for Accounting and Management Issues

Question: Discuss about theManagement Accounting for Accounting and Management Issues. Answer: We as a team of graduates are compelled to express concern about the response to our memo regarding how we at Company handle issues related to Accounting and Management issues. We would like to suggest a number of solutions for defined issues in the article. Since there are more athleisure options for women; we would suggest Nike to put forward Product Differentiation theory for consideration in order to attract women towards their brand as by having it there will be more superior quality products, improved customer service and innovative product features. Providing customers with a sales person who has good knowledge about the products will assist the customers to differentiate the products. Innovation can be a key source of Competitive advantage, the sooner an innovative product can be released into the market; the better will be Customers response. Focusing on Customer Relationship Management by collecting and analysing data to understand customers behaviour patterns and needs develops strong relationship with customers. We would recommend company to follow institutional theory in order to imitate competitors good practices to fascinate women who are turning their heads towards other brands. Moreover, to avoid product going out of style following pull system will be a good idea which is to hold inventory and manufacture products according to customer demands, Also they can have safety stock in case if customer demand increases. As Nikes Products came from 900 different material suppliers, company can drive sustainability improvements in materials focusing on value chain over which they have most of the control which is product design. Managers must look for opportunities to reduce the price of products. Value Analysis can be a helpful step in order to identify these opportunities. Deeply analysing the trends of Nike Inc. our team has also identified threat of Market Saturation for this company. As nowadays, Athletic shoe market is full of variety of companies and brands there is only a little space left for new entrants. Also new innovative products and growth of market shares are facing hardships to enter into market. Though Nike is holding a lead for its market share currently, they have just got a little room to expand more. In response to above threat we would like to convey Company to keep focus on Market Share and do not let other competitor companies steal their market share by taking broader market in mind including teenage generation who is interested in sports and extreme sports. There is a need to make sure that company stay active in whole athletic apparel market rather than athletic shoe market. In order to deal with its droping sales Nike has transformed the industry of athletic shoe with technological improvement and innovations. The company has understood that the most important thing is that it need to market its product. The design elements and functional aspects of the product forms the part of the overall marketing process. The company believes that it has to innovate for a specific reason and the reason originates from marketing. The company has been successful in keeping the manufacturing cost down whereas other companies are yet struggling to keep their cost low. Despite the fall in sales the company understood that it was missing core group of consumers. In order to boost up its sales and the core consumer group the company has come with the strategy of meeting up with the consumer wants. To understand the consumer wants the company visit the amateur sports events and spends time with the consumer. This helps Nike in ensuring that product meets the quality and dem and of the consumers. Understand the consumers forms the best forms of marketing for Nike. The entire experience forced the company to rule certain products that did not met the consumer wants. https://www.managementexchange.com/story/nike%E2%80%99s-gameplan-growth-that%E2%80%99s-good-all Reference List: Hollensen, S., 2015.Marketing management: A relationship approach.

The Study Of Western Political Thought Has Endured A Drastic Change Th

The study of western political thought has endured a drastic change throughout the centuries. This shift occurred through the queries of ancient philosophical minds such as Plato, Aristotle, the Stoics, and St. Augustine. Two examples of great importance are the inequality of gender and the role of power distributed and issued within the state. Plato believed all people, men and women alike are created equal; this notion runs parallel to our modern day Constitution. He states "if we are to set women to the same tasks as men, we must teach them the same things," they must endure "training for the mind and body and also be taught the art of war" (149). Plato developed a role known as a guardian or a soldier to protect over the people. He relates this to the fact that if watchdogs can be both male and female why can't guardians. Aristotle is known as Plato's greatest pupil. He was strongly influenced by the teachings of Plato but was also known for ridiculing some of his ways. His view of women is drastically different from those of Plato. By nature, he says, women are to be dominated by men. Aristotle refers to women as imperfect men. He acknowledges that women can possess reason, but can not obtain the same stature as men. Aristotle believes the only purpose that women serve is to provide matter for the child and the men provide the form. His ideas of form and matter are very different from that of Plato, since his beliefs are void of matter holding only form as the essence behind life. The beginning of Stoic philosophy formed a totally different view on the idea of equality. Equality was no longer devised with respects to a community in the whole, but rather as individuals. The Stoics developed a system consisting of three classes. Everyone within each particular class was considered equals. They were strong followers of the concept of natural law, which meant both men and women can reason. Their reasoning was treated in the same respects no matter what gender; this statement is very different from that of Aristotle. Zeno, the founder of the Stoics, believed in the notion of brotherhood among all, men and women alike. St. Augustine took the Stoics ideas of equality one step further. His views pertain to that of the Christian approach. Augustine believed that people were all equals within the City of God. Spiritually women were identical to men, but physically they shared many differences. This idea of equality holds true even to present day. These paragraphs demonstrate a tremendous change in the equality of women within society. Another example that was greatly impacted by these time periods was the change in the role of power distributed and issued within the state. Plato held the belief of the philosopher king. He believed to ensure the ideal state "either philosophers (were to) become kings in their countries or those who are now called kings and rulers come to be sufficiently inspired with a desire for wisdom" (179). Plato believed only the wise could execute proper justice. A just city is an ideal city for Plato, one in which the philosopher was in total control. Aristotle's views greatly differ from Plato's. Aristotle believed that each individual in their self made the polis. He compares having only one person as a "hand" (112) without a body, put that hand with the rest of the body and it can work to its fullest potential. This describes individuals working as a whole to better the polis. By including all citizens Aristotle believed he had created the ideal city. During the time of the Stoics, many important philosophers gave their opinions about the issues of authority within the state. As stated previously, Zeno was a strong believer of the brotherhood among all. The Stoics notion of natural law granted all people within the state, of any class, to be offered the ability to share their opinion of government. Another philosopher, Polibius, agreed with Aristotle's concept of mixed constitution. Government was gradually moving away from the days of Plato. Augustine defined the Christian rule of the Church over state. In order to have the ideal government, Augustine believed law should co-relate to that of the Church.

How to Write Great Ledes for Feature Stories

How to Write Great Ledes for Feature Stories When you think of newspapers, you probably tend to focus on the hard-news stories that fill the front page. But much of the writing found in any newspaper is done in a much more feature-oriented way. Writing ledes for feature stories, as opposed to  hard-news ledes, requires a different approach. Feature Ledes vs. Hard-News Ledes Hard-news ledes need to get all the important points of the story - the who, what, where, when, why, and how - into the first sentence  or two, so that if the reader only wants the basic facts, he or she gets them quickly. The more of a news story he or she reads, the more detail he gets. Feature ledes, sometimes called delayed, narrative, or anecdotal ledes, unfold more slowly. They allow the writer to tell a story in a more traditional, sometimes chronological way. The objective is to draw the readers into the story and to make them want to read more. Setting a Scene, Painting a Picture Feature ledes often begin by setting a scene or painting a picture of a person or place. Here’s a Pulitzer Prize-winning example by Andrea Elliott of The New York Times: The young Egyptian professional could pass for any New York Bachelor. Dressed in a crisp polo shirt and swathed in Cologne, he races his Nissan Maxima through the rain-slicked streets of Manhattan, late for a date with a tall brunette. At red lights, he fusses with his hair. What sets the Bachelor apart from other young men on the make is the chaperone sitting next to him - a tall, bearded man in a white robe and stiff embroidered hat. Notice how Elliott effectively uses phrases like â€Å"crisp polo shirt† and â€Å"rain-slicked streets.† The reader doesnt yet know exactly what this article is about, but he or she is drawn into the story through these descriptive passages. Using an Anecdote Another way to begin a feature is to tell a story or an anecdote. Here’s an example by Edward Wong of The New York Times Beijing bureau: BEIJING - The first sign of trouble was powder in the baby’s urine. Then there was blood. By the time the parents took their son to the hospital, he had no urine at all. Kidney stones were the problem, doctors told the parents. The baby died on May 1 in the hospital, just two weeks after the first symptoms appeared. His name was Yi Kaixuan. He was 6 months old. The parents filed a lawsuit on Monday in the arid northwest province of Gansu, where the family lives, asking for compensation from Sanlu Group, the maker of the powdered baby formula that Kaixuan had been drinking. It seemed like a clear-cut liability case; since last month, Sanlu has been at the center of China’s biggest contaminated food crisis in years. But as in two other courts dealing with related lawsuits, judges have so far declined to hear the case. Taking Time to Tell the Story You’ll notice that both Elliott and Wong take several paragraphs to begin their stories. That’s fine - feature ledes in newspapers generally take two to four paragraphs to set a scene or convey an anecdote; magazine articles can take much longer. But pretty soon, even a feature story has to get to the point. The Nut Graph The nut graph is where the feature writer lays out for the reader exactly what the story is all about. It usually follows the first few paragraphs of the scene-setting or storytelling the writer has done. A nut graph can be a single paragraph or more. Here’s Elliott’s lede again, this time with the nut graph included: The young Egyptian professional could pass for any New York Bachelor. Dressed in a crisp polo shirt and swathed in Cologne, he races his Nissan Maxima through the rain-slicked streets of Manhattan, late for a date with a tall brunette. At red lights, he fusses with his hair. What sets the Bachelor apart from other young men on the make is the chaperone sitting next to him - a tall, bearded man in a white robe and stiff embroidered hat. I pray that Allah will bring this couple together, the man, Sheik Reda Shata, says, clutching his seat belt and urging the Bachelor to slow down. (Here is the nut graph, along with the following sentence): Christian singles meet for  coffee. Young Jews have JDate. But many Muslims believe that it is forbidden for an unmarried man and woman to meet in private. In predominantly Muslim countries, the job of making introductions and even arranging marriages typically falls to a vast network of family and friends. In Brooklyn, there is Mr. Shata. Week after week, Muslims embark on dates with him in tow. Mr. Shata, the imam of a Bay Ridge mosque, juggles some 550 marriage candidates, from a gold-toothed electrician to a professor at Columbia University. The meetings often unfold on the green velour couch of his office or over a meal at his favorite Yemeni restaurant on Atlantic Avenue. So now the reader knows – this is the story of a Brooklyn imam who helps bring young Muslim couples together for marriage. Elliott could just as easily have written the story with a hard-news lede something like this: An imam based in Brooklyn says he works as a chaperone with hundreds of young Muslims in an effort to bring them together for marriage. That’s certainly quicker. But it’s not nearly as interesting as Elliott’s descriptive, well-crafted approach. When to Use the Feature Approach When done right, feature ledes can be a joy to read. But feature ledes aren’t appropriate for every story in print or online. Hard-news ledes are generally used for breaking news  and for more important, time-sensitive stories. Feature ledes are generally used on stories that are less deadline-oriented and for those that examine issues in a more in-depth way.

Changing tax laws to reduce tax avoidance through the use of Research Paper

Changing tax laws to reduce tax avoidance through the use of partnerships - Research Paper Example Lipatov, (2011) argued that it is unfair for a common man earning a meager income that is just enough to sustain themselves to be charged every penny of his revenue whereas big companies and wealthy people are exempted through avoidance of taxation. Non-remittance does not only reduces government revenue but also brings the taxation system into disrepute therefore authorities charged with taxation needs to prevent avoiding tax or keep it within check (Desai & Dharmapala, 2006). According to PWC (2012), Majority of those involved in tax avoidance usually invoke section 88 and section 100 of the income tax act in order to shield themselves. Section 88 have therefore been barred from being referred to when the gain from the interest of partnership far exceeds the cost of the asset fair market value (Government of Canada, 2012). The budget proposals have also propose for the application of section 100 up to the point of sale of partnership interest to the person who is not a resident of the place in reference, this will however be an exception in a situation whereby is carrying out its activities through a permanent establishment (Mullainathan, Schwartz stein, & Congdon, 2012). A Partner should also be able to waive on behalf of all his partners within a three year limit for making a determination (2012 Federal Budget Commentary). The law should be clear enough according to Rosenberg (1989) because this will stop the taxpayer`s personal exertion income being taken as being income of the partnership and later being diverted as the companies` loss under the agency and management agreements. Reason being surpluses or net profits from those monies will be forwarded from that partnership daily to the group finance companies (Batt, 2012). The partnership acts should introduce various amendments to the taxes acts, that is according to the Blundell (2011) view. These

Every supplement gaining for approval of government to enter the market includes tonnage of paper works and tedious process. With the current situation of the state where the supplements are freely roaming the stores and pharmacies, and there are some drugs that are easily bought over the counter, their move to regulate them may cause these products to be out of market. This can hurt the public especially those who are relying on affordable ways to get treatment for their sickness. There is no therapeutic claim for supplements that is a bare fact. But it can not be denied that there are positive effects that these supplements give to human bodies that’s why people keep on patronizing them. When strict regulations on these products are ruled out, some of these supplements can possibly fade in the market circulation causing people relying on them to lose their chances of achieving good health in cheaper and easier ways. People from the government imposing bills and laws must see to the general welfare of the public first. If laws imposed can cause decline for public health, then I think they should think and rethink the limitations of the law to make it beneficial to

Altruism among humans Essay Example for Free

Altruism among humans Essay This paper presents an examination of the phenomenon of altruism among humans. Altruism is defined as a behaviour that may be to ones advantage but is also to the advantage of others. The questions of why we behave this way or what motivates us to behave in this manner and the relevance to society today are the focus of this paper. Various research and theories has explained why altruistic behaviour is undertaken intentionally in the human world. Introduction We often read or hear about acts of generosity and courage, such as, fund raisers or concerts to  help homeless people, the fostering of a child and sponsoring his or her education, or of volunteers risking their lives to help victims in incidents like September 11 terrorist attack in the United States. We could have donated some money to orphanages or cared for a wounded dog. Such humane acts are defined by Psychologists as altruism (Moghaddam, 1998). Altruistic acts could be unselfish or done for personal gain or egoistic reasons. Indeed in a psychological paradigm, psychologists believe that true altruistic behaviour does not exist (Moghaddam, 1998). But how do we account for the behaviour of Mother Theresa or Mahatma Gandhi and many other unselfish acts of human endeavours? In order to explore this we have to understand the person variable and situational variable motivating the altruistic act (Simons, Kalichman Santrock, 1994). As we are aware behaviour is determined by personal and situational variables. A persons ability to empathise with the needy or to feel responsible for anothers welfare has great impact on altruistic behaviour. Situations influence the strength of the altruistic motivation. Reciprocity and exchange are important aspects of altruism (Simons, Kalichman Santrock, 1994). Humans give and receive from others everywhere. Reciprocity is the basic principle of every religion in the world for example, Judaism, Hinduism, Christianity, Buddhism and Islam (Brosnahan, 2003). To act altruistically, requires consciousness and caring, and similarly, pet owners can often cite altruistic behaviour or at least conscious acts of kindness on the part of cats and dogs (Simons, Kalichman Santrock, 1994). Another good example would be the nursing,  profession founded on the notion of helping people, sometimes even at a cost to nurses themselves. There are many ways people show altruism. To explain why we do altruistic acts like volunteering, donating or raising funds, we need to distinguish between four different forms of altruism which are observed in humans that shown towards kin, a partner, a friend, and individual who does not fit into these categories (http://www. theunityofknowledge. org/the_evolution_of_altruism/introduction. htm, 2003) Of the several types of altruism a main focus has been on heroic altruism (Moghaddam, 1998). It is a short term intervention requiring physical action and tends to fit more the masculine gender. On the other hand Nurturant altruism requires more patience, listening and a caring attitude with long term involvement. This more closely fits the image of the traditional feminine gender (Moghaddam, 1998). The Bystander effect greatly influences helping behaviour, because of common ignorance of bystanders and assumptions about other bystanders actions. Each persons scope of responsibilities can decrease in the presence of others ( Moghaddam, 1998). In  order for Bystander to help he or she has to posses social skills to interpret the situation and take appropriate actions (Moghaddam, 1998). Initially from a theoretical perspective if a person knows how to overcome obstacles to he or she giving help, subsequently other people start questioning whether the helping behaviour was true altruism (Moghaddam, 1998). A later there was a theory of Daniel Batson empathy-altruism, believes that people help out of a genuine desire(Moghaddam, 1998). Other theories propose that altruistic behaviour is egoistic and put the hypothesis that helping behaviour is a way to  repair a helpers image (Moghaddam, 1998). Methodology An interview was conducted with a woman who volunteers her services with meals on wheels and has done nearly sixteen years. She is a retired school teacher living alone. I assumed that her altruistic behaviour had a self fulfilling motive. Therefore I chose her and I wanted to clarify or confirm my assumption. In order to facilitate my focus interviewee was given ten questions asking about her volunteering profile, and her motivating factors. This interview created awareness of other influencing factors motivating her altruistic behaviour.

evilmac darkmac Darkness, Evil and Tragedy in Shakespeares Macbeth :: Free Macbeth Essays

Macbeth: Darkness, Evil and Tragedy Macbeth is a play full of darkness, evil, and tragedy. It is the story of a man who goes against his conscience and commits a horrible deed which leads to his destruction and loss of everything he has around him. This includes the relationship he has with his wife, Lady Macbeth. In the end, he can blame no one but himself. At the beginning of the play, Macbeth and Lady Macbeth have a very strong relationship and this deteriorates later. Act 1 Scene 5 is a key scene which shows just how close Macbeth and Lady Macbeth were at the beginning of the play; it shows their original relationship. Macbeth has written a letter to Lady Macbeth telling her of everything and in this letter states algo that she helped him to get everything for him. The following speech where Lady Macbeth doubts that he can get to the title of King "he is too full of the milk of human kindness" shows just how close they were. It establishes the fact that she knew him so well, she knew what he was like and it emphasises the closeness of their relationship. She speaks of how he has enough ambition but not enough courage. His "overiding ambition" is not enough. When Macbeth and Lady Macbeth speak, they speak to eachother with such closeness and bond; he calls her his "dearest chuck", his "partner of greatness". She knows that he is too weak to do anything and states her position in the murder "leave the rest to me". In Act 1, Scene 7 establishes the force and power that Lady Macbeth posseses over her husband. Upon hearing of Macbeth's decision not to kill Duncan, she is outraged and starts to work her force and power upon him. She knows where he is most vulnerable and attacks him at his weak spot. She strikes him at his manhood and courage. This of course works on Macbeth and she knows that it will. No one calls Macbeth a coward. She says that he is a coward and attacks his manliness. "to be more than what you are, you would be so much more the man". She challenges his love for her and says that she would rather "dash the brains out" of her own child than break such a promise as Macbeth has to her. Whether she was bluffing, the imagery that Macbeth would have had in his mind at this point would have been frightening. To have the brains "dashed out" of his own child.

Design Of Baffle In Upflow Anaeorobic Engineering Essay

The Upflow Anaerobic Sludge Blanket procedure was developed by Lettinga in the Netherland during the early 1980s, as a comparatively simple effluent intervention system, in which no moving parts are present ( Lettinga et al, 1980 ) . It was foremost proposed for the intervention of high strength industrial waste, but shortly research for its application besides within domestic sewerage intervention was initiated. The UASB reactor is now going a popular intervention method for industrial H2O, because of its effectivity in handling high strength effluent. From the Seghezzo et Al. ( 1998 ) , the characteristics which make UASB reactor to be popular: High efficiency. Availability of farinaceous or woolly sludge, leting it to accomplish high chemical O demand ( COD ) remotion efficiencies without the demand of support stuff. Furthermore, the natural turbulency caused by caused by lifting gas bubbles which buoy the sludge, provides efficient effluent and biomass contact. Simplicity. The building and operation of the reactor is comparatively simple. Flexibility. Anaerobic intervention can easy be applied on either a really big or a really little graduated table. Besides, due to the granulation/blanketing in a UASB reactor, the solids and hydraulic keeping clip can be manipulated independently and efficaciously, therefore allowing the design to be based upon the degradative capacity of the biomass, ensuing in the decrease of intervention times from yearss to hours. ( Hickey et al. 1991 ) Low energy ingestion. Equally far as no warming of the influent is needed to make the on the job temperature and all works operations can be done by gravitation, the energy ingestion of the reactor is about negligible. Furthermore, energy is produced during the procedure in the signifier of methane. Low sludge production. The sludge production is low, when compared to anaerobic methods, due to the slow growing rate of anaerobiotic bacteriums. The sludge is good stabilized for the concluding disposal and has good dewatering features. It can be preserved for long periods of clip without a important decrease of activities, leting its usage a inoculant for the start-up of new reactors. Low foods and chemical demand. Particularly in the instance of sewerage, an equal and stable pH can be maintained without the add-on of chemicals. The UASB has been successfully used in the recent yesteryear to handle a assortment of industrial every bit good as domestic effluent. The applications for this engineering are spread outing to include intervention of chemical and petrochemical industry wastewater, fabric industry effluent, landfill leachates, every bit good as applications directed at transitions in the sulfur rhythm and remotions of metals. Furthermore, in warm climes the UASB construct is besides suited for intervention of domestic effluent.1.2 PROBLEM STATEMENTThe design and optimisation of Upflow Anaerobic Sludge Blanket ( UASB ) reactor units required cognition of bio dynamicss, commixture, chemical reaction and else. However, the hydrokineticss within a UASB reactor is a critical importance to the public presentation of the system. Current effluent intervention design methods make premises of the commixture conditions and it is hence hard to foretell how vessel design for illustration, place of recesss, baffle s or dimensions which could impact hydrokineticss, therefore overall public presentation. Besides, the applications of the experimental techniques to look into flow Fieldss and mass concentration Fieldss are highly dearly-won and besides extremely limited in application. Thus, an appropriate factor which is design of baffles had been chosen ; and investigated the influences of hydrokineticss and public presentations of UASB reactor in this survey. Computational Fluid Dynamics ( CFD ) provides a mathematical method for anticipation of the consequence that effluent intervention procedure design features on the hydrokineticss from a cardinal degree. Progresss in CFD have provided an efficient, economical and clip salvaging tool to look into the hydrokineticss and reaction transition happening in a UASB reactor.AimThe thesis has two chief aims ; foremost is to carry on the public presentation survey of the designed Upflow Anaerobic Sludge Blanket ( UASB ) reactor which can be applied to full graduated table systems. The Computational Fluid Dynamics ( CFD ) theoretical account presented here has the ability to pattern multiple stages ( in this instance the sludge mixture with H2O and air ) . Besides, the CFD theoretical account was developed and applied for the building of existent scale theoretical account. The 2nd aim is to analyze the effects of baffles to the hydrokineticss for illustration the fluid commixture form, flow field, matching and of the 3 stages ( liquid, solid and air ) of waste H2O intervention procedure. In this survey, the experiment would carry on with befuddled UASB reactor and the other is un-baffled UASB reactor to further analyze the influences to the hydrokineticss and overall public presentations.Chapter 2LITERATURE REVIEW2.1 TREATMENT PRINCIPLE OF UPFLOW ANAEROBIC SLUDGE BLANKET ( UASB ) ReactorThe Upflow Anaerobic Sludge Blanket ( UASB ) procedure consists of an upflow of effluent through a dense sludge bed with high microbic activity. In the reactor, the solids profile varies from really heavy and farinaceous atoms with good settee ability near to the underside ( sludge bed ) , to more spread and light sludge atoms near to the top ( sludge cover ) . The UASB reactor can be divided into four constituents: sludge bed, sludge cover, gas-solid-liquid centrifuge and secondary compartment above the centrifuge. The sludge bed is situated at the underside of the reactor and consists of a dense sludge with exceeding subsiding features ; it is hence kept in the reactor. Above the sludge bed is the sludge cover, with solid showing lower concentration and settling speeds. The sludge cover consists of sludge atoms in a mixture with the biogas formed, and is therefore held in suspension. It is in these two compartments, the sludge bed and the sludge cover, that the entrance effluent is biologically degraded ( Chernicharo, 2007 ) .BiogasSludge atomGas bubblesBaffleSludge BlanketSludge bedDigestion CompartmentSettling Compartment3-phase centrifugeFigure 1 UASB reactorThe effluent flows upward in a perpendicular reactor through a cover of granulated sludge and bacteriums in the sludge interrupt down organic affair by anaerobiotic digestion, tran sforming it into biogas. The biogas-production and the influent flow cause natural turbulency in the reactor, which provides a good wastewater-biomass contact in the UASB reactor system ( Heertjes al. , 1978 ) . The upflow government and the gesture of the gas bubbles allow blending without mechanic aid. To avoid sludge washout, the 3 stage centrifuge is installed in the upper portion of the reactor. The gas formed is separated from the liquid, which allow sludge keeping and return. Above the centrifuge, a gas free zone is formed which is settling compartment, for deposit of solid atoms, and most of the atoms that have entered this zone will settle back to the reactor, whereas the smallest atoms will be washed out with the wastewater ( Angelidaki et al, 2007 ) . Baffles at the top of the reactor allow gases to get away and forestall the escape of the sludge cover. The 3-phase centrifuge, or the gas-liquid-solid ( GLS ) centrifuge, enables a high keeping capacity of big sums of high-activity biomass in the reactor. Through this characteristic, a solids abode clip ( SRT ) much higher than the hydraulic keeping clip can be achieved. Consequently, the care of high SRT is the major point of involvement in practical application of UASB procedure. This ability to develop and keep high-activity sludge within the reactor is the most of import facet of the UASB construct ( Chernicharo, 2007 ) .2.2 ANAEROBIC PROCESS IN THE UASB REACTORIn UASB reactor, anaerobiotic micro-organisms in the sludge cover digest the organic pollutants in the entrance effluent. Anaerobic digestion produces biogas ( a mixture of methane CH4, C dioxide CO2 and hints gases ) . After some hebdomads of ripening, farinaceous sludge signifiers and this is the chief outstanding feature of UASB reactor named phenomenon of granulation. The formation of granules is really of import becaus e bacteriums in granules are more efficient for biogas production than the flocculated biomass ( Wendland2008 ) . The anaerobiotic farinaceous sludge consists of microbic communities, with 1000000s of micro-organisms per gm biomass. Normally the granules are grouped dumbly together and hold first-class settling ability. The size wise each granule ranges from 0.1to 5mm. The microstructure of each granule will be dictated by the substrate features of the influent, for simple substrates merely methanogens are needed for complete debasement. For complex substrates, by and large the different bacterial populations will group together selectively in beds on top of each other ( Tiwari et al, 2006 ) . The farinaceous sludge enables the keeping of a really high figure of micro-organisms in the reactor, which means that a rapid debasement of organic affair can be obtained. In bend, a big volume of waste can be treated within a volume that takes up merely little sum of infinites. Besides, anaerobic sludge has or acquires good deposit belongingss, and is automatically assorted by the upflow forces of the entrance effluent and gas bubbles being generated in the reactor. For that ground, mechanical commixture can be omitted from an UASB reactor and therefore cut downing capital and care costs. This commixture besides encourages the formation of sludge granules.2.3 DESIGN CONSIDERATIONS OF UASB REACTORThe UASB reactor can be designed as handbill or rectangular. It is necessary to choose proper scope of operating parametric quantities for design, such as organic lading rate ( OLR ) , SLR, superficial liquid upflow speed and hydraulic keeping clip ( HRT ) . By and large, there are two ways to plan UASB reactor which are based on HRT or OLR. In the instance of low strength effluent, such as sewerage, it is the HRT instead than the OLR that determines the design method of UASB reactor. In position of the instead low organic tonss that can be applied in the intervention of dilute effluent, and the lower blending ensuing from the gas production, it is evident that more recess points are needed, in comparing with the same reactor under high organic burden rates condition ( Lettinga et al, 1983 ) .2.3.1 Low strength effluent – Hydraulic Retention TimeFor low strength effluent with COD input less than 5000mg/l, the design method should be calculated based on the HRT which can be controlled by volumetric hydraulic burden. It is note that HRT means the step of the mean length of clip that a soluble compound remains in the reactor. Anaerobic digestion depends on the biological activity of comparatively slowly reproducing methanogenic bacte riums. These bacteriums must be given sufficient clip to reproduce, so that they can replace cells loss with the wastewater sludge, and adjust their population size to follow fluctuations in organic burden. If the rate of bacteriums loss from the digester with the wastewater slurry exceeds the growing rate of the bacteriums, the bacterial population in the digester will be â€Å" washed out † of the system. This washout is avoided by keeping a sufficient HRT for guaranting that the bacterial cells remain in optimum concentration within the digester. The longer a substrate is kept under proper reaction conditions the more complete its debasement will go. However, the reaction rate will diminish with increasing HRT. Thus, the sum of effluent applied day-to-day to the reactor, per unit volume, is termed the volumetric hydraulic burden: ( 2.1 ) where: VHL = volumetric hydraulic burden ( d-1 ) Q = flow rate ( m3/d ) V = entire volume of reactor ( M3 ) The hydraulic keeping clip ( HRT ) , given in yearss, is expressed as ( 2.2 ) which gives that, ( 2.3 ) For tropical climes and semitropical climes experimental consequences showed that a HRT of six hours was sufficient to accomplish satisfactory consequences in a one compartment UASB. In table 1 nowadayss some guidelines for the constitution of HRTs in design of UASB reactors handling domestic effluent. Table 1: Applicable Hydraulic detainment clip for natural domestic effluent in a 4m tall UASB reactor at assorted temperature ranges. ( adopted from Lettinga et Al, 1991 ) Sewage temperature ( A °C ) HRT ( H ) Daily Average Minimum ( during 4 to 6 H ) 16-19 & gt ; 10 – 14 & gt ; 7 – 9 20-26 & gt ; 6 – 9 & gt ; 4 – 6 & gt ; 26 & gt ; 6 & gt ; 42.3.2 High strength effluent – Organic burden rateIn the COD input between 5000 – 15000mg/l or more, the design method should be calculated based on OLR. Bacteria have a maximal production rate depending on the type of reactor and substrate. The OLR is one of parametric quantities used to depict this production rate. Bacteria and micro-organisms have their specific growing rate that will accomplish a maximal production rate when they degrade substrate. Therefore, different OLR give different impacts to the reaction rate and efficiency every bit good. By definition, the volumetric OLR is the sum of organic affair applied daily to the reactor, per volume unit: ( 2.4 ) where: OLR = organic burden rate ( kgCOD/m3d ) S = influent substrate concentration ( kgCOD/m3 ) COD intervention efficiency can be calculated by: ( 2.5 ) For COD concentration in the scope of 2 to 5g/L. the public presentation of the reactor depends on the hydraulic burden rate and is independent of inflowing substrate concentration. For COD concentration greater than 5g/L it is recommended to thin the effluent to about 2g COD/L during primary start up of the reactor. Once the primary start – up of the reactor is over with the granulation of sludge, lading rates can be increased in stairss to convey the existent COD concentration of the effluent. The lading above 1-2kg COD/m3d is indispensable for proper operation of the reactor.2.3.3 Upflow speed, reactor tallness and volumeHigher upflow speed, favours better selective procedure for the sludge and better commixture in the reactor. However, excessively high upflow speed may do the incolumn acquire washed out during start up. Besides, during normal operation granules may acquire disintegrated and the ensuing fragments can easy be washed out from the reactor. Therefore, design th e optimal liquid upflow speeds ensuing favourable for granule growing and good fluid blending with the activated sludge. The upflow speed, V, is calculated from the relation between the inflowing flow rate and the cross subdivision of the reactor: ( 2.6 ) where: V = upflow speed ( thousand / H ) A = cross sectional country of the reactor ( M2 ) Alternatively, the upflow speed can besides be calculated from the ratio of the tallness and the hydraulic keeping clip: ( 2.7 ) where: H = tallness of the reactor ( m ) The pick of appropriate tallness of the reactor depends on the needed public presentation and economic considerations. Another of import facet is the place of the underside of the reactor, comparative to anchor degree. Construction costs can be reduced if the reactor underside can be placed at such degree that no pumping system of influent is required. The reactor tallness besides has importance for the efficiency of the organic affair remotion, as the upflow speed must non transcend the bound where the sludge washed out. The upflow speed, and reactor tallness are closely related in Equation 2.7. Based on the higher suited value of OLR, for given COD concentration, the volume of the reactor required is to be worked out as: ( 2.8 ) The volume of sludge should be less than 50 % of the reactor volume, worked out based on OLR, to avoid overloading of the reactor with regard to SLR. If the volume is non run intoing the demands, the OLR can be reduced to increase the volume.2.3.4 Influent Distribution SystemIt is of critical importance that the influent substrate is equally distributed in the lower portion of the reactor. Otherwise a close contact between biomass and substrate can non be obtained. The gas production will ever lend well to the commixture of the sludge bed, and hence the commixture within the digestion compartment will typically be hindered when handling effluent. Poor blending can take to the creative activity of discriminatory tracts through the sludge bed. For illustration, hydraulic short circuits, which in the long term will give a shorter sludge bed height and the formation of dead zones in the sludge bed ( Lettinga et al, 1991 ) . To avoid this job, the influent should be introduced at several points from the reactor underside. A particular influent distribution system can vouch equal distribution over the full reactor surface country. Therefore, the influent so passes a dense and expanded anaerobiotic farinaceous biomass bed and the biological intervention expeditiously. The figure of distribution pipes needed depend on the country of the cross subdivision of the reactor. Chernicharo ( 2007 ) suggests that Equation 2.9 be used to find the figure distribution pipes: ( 2.9 ) where: Nx = figure of distribution tubings A = country of cross subdivision of the reactor ( M2 ) Ax = influence country of each distributer ( M2 )2.4 Fluid Mixing In UASB ReactorThe flow form in the UASB reactor is one of the most of import factors to be considered for design to ease an efficient intervention. The efficiency of all bioprocesses is closely connected with commixture and conveyance phenomena, as an even blending form will supply good conditions for substrate conveyance to and from the microbic sums. Therefore, the transition of organic affair in the UASB reactor is governed by non merely the public presentation of the microbiological procedures, but besides the hydrokineticss of the reactor. However, the behaviour of the UASB procedure is non to the full understood. The commixture inside a UASB reactor is related to several parametric quantities, such as the type of influent-feeding device, upflow speed and biogas production rate, and different surveies have used different theoretical accounts to depict its hydrokineticss. Heertjes et Al ( 1978 ) assumed the flow to be wholly assorted within the sludge bed and sludge cover, although the sludge bed could besides hold dead infinites and returning flows. The more accurate theoretical accounts of the UASB fluid mechanicss where late highlighted by both Zeng et Al ( 2005 ) and Lou et Al ( 2006 ) , saying that the bing mathematical theoretical accounts of anaerobiotic digestion in UASB reactors mostly assume ideal commixture, therefore pretermiting concentration gradients. To make a more right theoretical account of the reactor fluid mechanicss, Zeng et Al ( 2005 ) alternatively used a two-compartment theoretical account, with the sludge bed and liquid zones described by a two-zone axially spread system. The survey showed that in a UASB reactor there is a strong dependance of the scattering coefficient on both reactor tallness and upflow speed.2.4.1 Computational Fluid Dynamics ( CFD )With visual aspect of general intent codifications, such as FLUENT, CFX and others, Computational Fluid Dynamics ( CFD ) has become progressively popular in environmental engineering. CFD codifications besides can be used to visualise elaborate flow phenom ena, a important benefit for the measuring of parametric quantities such as force per unit area, speed, phases volume fraction and else. The work mentioned above chiefly concentrated on using CFD codifications to obtain UASB reactor hydrokineticss informations, therefore doing good suggestions for UASB reactor design and optimisation. The theoretical accounts used were simplified two stages or individual stage systems. Related UASB reactor simulation based on gas-liquid-solid three stage theoretical accounts and flow procedure related reaction dynamicss theoretical accounts widely studied. For the first clip, the focal point lies on set uping hydrodynamics-reaction dynamicss coupled theoretical account of a gas-liquid-solid three stage waste H2O intervention system utilizing CFD simulation followed by experimental confirmation in this paper. Although UASB reactor has been used in environmental engineering applications for many old ages, lithe research has been published on UASB reactor mold. The chief aims of this survey are to develop an easy to utilize of CFD theoretical account of the important procedure parametric quantities, based on cardinal scientific discipline and to formalize the theoretical account by usage of experiment consequences. Due to non much researching on baffled UASB reactor, our conjugate theoretical account was applied and validated on a waste H2O intervention procedure and look into the overall public presentation. Once developed and assessed with the all-out test consequences, the theoretical account can be employed to analyse the consequence of waste H2O quality features on the public presentation of the procedure. It is expected that this survey will turn out utile in using UASB engineering.Chapter 3Methodology3.1 Computational Fluid Dynamics ( CFD ) simulationThe commercial Computational Flui d Dynamics ( CFD ) codification ANYSYS FLUENT was used to imitate the two and three dimensional flow field before building of the Upflow Anaerobic Sludge Blanket ( UAB ) reactor. A conceptual theoretical account was developed by the package and this proposed CFD theoretical account is composed of the nucleus hydrokineticss theoretical account for the liquid and gaseous stages, and coupled with the sludge. CFD simulation helps to depict flow of the liquid and gas constituents of the multiphase flow. The uninterrupted stage is the effluent and sludge and the spread stage is air or biogas. The premises made for the spread stage are: The bubbles are spherical The bubbles have changeless diameter No hits, coalescency or break-up of bubbles The gas stage physical belongingss for illustration denseness and viscousness were air belongingss. For the liquid stage, the denseness was considered to be that of H2O, while in footings of viscousness.3.1.1 Eulerian-Eulerian theoretical accountThis theoretical account is help to work out a set of impulse and continuity equations for each stage. Applications of Eulerian multiphase theoretical account include bubble column, risers, atom suspensions and fluidized beds ( Saurel and Abgrall 1999 ; Mathisesen et al.2000 ) . In this survey, two dimensional Eulerian-Eulerian three stage fluid theoretical account has been employed to depict the flow behaviour of each stage, so the biogas, effluent and sludge granules are wholly treated as different continua, with effluent as a primary stage, and the gas and sludge granules as the secondary stages. This theoretical account was chosen because of the high proportion of gas bubbles and granules particulates ( Bin et al. 2003 ) .3.1.2 Species Tr ansport and Reaction theoretical accountCFD codifications can pattern the commixture and conveyance of chemical species by work outing preservation equations depicting convection, diffusion and reaction beginnings for each constituent species ( Sivertsen and Djilali, 2005 ) . Multiple coincident chemical reactions can be modeled, with reactions happening in the majority stage ( volumetric reaction ) , on inside wall of the reactor or atom surfaces.3.1.3 Numeric solutionThe complete geometry of the UASB reactor have analyzed by a computational planar mesh. For efficiency usage of computational clip, simulation of the UASB reactor exploits the symmetric geometry of the reactor in a planar surface. The meshes were created in the ANYSYS Fluent as a preprocessor plan and exported into the ANYSYS Fluent CFD flow patterning package bundle to work out the continuity and impulse equations. In Eulerian-Eulerian theoretical account, each stage was assumed incompressible. The effluent was regarded as assorted liquid, ab initio incorporating pure H2O and some chemical wastes and the denseness was determined by utilizing a volume weighted mixing jurisprudence. The sludge granules took up approximately 35 % of the volume in the bed part and were considered to be 1mm diameter spherical solid granules. The biogas was assumed to hold a denseness by the incompressible-ideal-gas jurisprudence ( FLUENT 6.0 Users ‘ usher, 2001 ) . The gas stage volume fraction was related to gas production in reaction and the gas bubbles were assumed to hold a diameter of 0.1 millimeter. The simulation consequences vary small with grid denseness so truncation mistakes in the numerical simulation can be neglected. An analysis independent of the grid was performed to extinguish mistakes in simulation truth, numerical stableness, convergence and computational stairss related to grid saltiness ( Ait-Ali-Yahia et al.2002 ; Lu et al,2009 ) .3.2 Experimental DesignThe research is conduct with two different types of UASB reactor theoretical account which are baffled and un-baffled to further analyze the influences of fluid blending form in the reactor. Figure 1 shows the conventional diagram with dimensions of 1m ten 0.2m. Degree centigrades: UsersKok FaiDesktopUASB.pngFigure 2: Conventional Diagram of the UASB reactor theoretical account. All units are in metre.Table 2: Chief characteristic of the UASB reactor theoretical accountParameter Value Design liquid flow rate ( l/h ) Hydraulic keeping clip ( H ) Entire Height ( m ) Water deepness ( m ) Sludge deepness ( m ) Internal diameter ( m ) Internal cross sectional country ( M2 ) Organic burden ( kg COD/m3/d )Table 3: composing of waste H2OIncoming waste H2O Value Entire BOD ( mg/l ) Entire COD ( mg/l ) Chloride ( mg/l ) Sulfate ( mg/l )–––One of the UASB reactors is baffled and the other one is un-baffled. Both of these reactors operated with the same hydraulic keeping clip, organic burden and composing of waste H2O which are the changeless variables in this experiment. The differences of the chemical waste substances removal efficiency between both reactors would be the consequence of this survey.3.2 Sampling and AnalysisComposite sample of the reactors influent and wastewater were collected on a day-to-day footing and analyzed for COD, BOD, sulphate and others chemical waste substances. Sludge sampling was carried out through side ports in the sludge zone of the reactor. The flow rate was control by the valve and continuously regulated by a pump.3.2.1 BOD trialBiochemical O demand ( BOD ) is the sum of dissolved O by aerophilic biological beings in a organic structure of H2O to breakdown organic stuff nowadays in a given H2O sample at certain temperature. BOD besides can be us ed as gage of the effectivity of UASB reactor. The process of the BOD trial: The dilution H2O was prepared by 1ml each of phosphate buffer, Mg sulphate, Ca chloride, ferrous chloride solution into 1L distilled H2O. 1ml effluent sample was added into a 500ml beaker. Dilution H2O was added up to 300ml into same beaker. The pH value was adjusted to 6.5 to 7.5 by added acid or base. 300ml dilution H2O was prepared as control. All prepared samples and control put in 300ml-incubation bottle. The DO for each sample was measured by utilizing Dissolved Oxygen Meter. All the bottles put in BOD brooder for 5 yearss. The temperature was set at 20A °C. The BOD5 was calculated harmonizing to the expression below: Where: D1 = DO value in initial sample D2 = DO value in concluding sample P = denary volumetric fraction of sample used Or ; Dilution factor = Bottle volume ( 300ml ) / sample volume3.2.2 COD trialThe chemical Oxygen Demand ( COD ) trial measured the O equivalent consumed by organic affair in a sample during strong chemical oxidization. It can assist to foretell the O demands of the wastewater and is used for monitoring and control of discharges, and for accessing reactor public presentations. The trial method: The effluent sample was oxidized by digesting in a certain reaction tubing with sulfuric acid and K bichromate in the presences of a Ag sulfate accelerator for 2 hours at a temperature of 150A °C. The sum of bichromate reduced is relative to the COD. A reagent space was prepared for each batch of tubings in order to counterbalance for the oxygen demand of the reagent itself. Over the scope of the trial a series of colourss from xanthous through green to blue are produced. The colour is declarative of the chemical O demand and its measured by utilizing photometer.

A key element of unfolding the story in the action movie genre Essay

Violence is a key element of unfolding the story in the action movie genre. It is used to make sense of the narrative for the audience, gradually revealing character traits as well as intentions. In summation to this violence in the action movie genre often follow certain narrative conventions; including binary oppositions, Todorov’s disequilibrium as well as open endings and linear/non-linear narratives. Movies that conform to these stereotypes are often successful, movies such as Die Hard or more censored action movies such as Logan or Deadpool which follow the binary opposition style of narrative where the protagonists aim within the movie is to â€Å"train† to eventually take down the antagonist, oppositions may include – (Good vs. evil, rich vs. poor and man vs. woman) In addition to this the listed movies follow Todorov’s theory of disequilibrium where everything is in one piece until the antagonist is introduced only then will chaos arise. However, action movies that challenge these usual narratives leave options for the audience as to how they think the movie is going to end; movies such as Avatar are examples of this. This importance of violence in action movies are reinforced and undermined in the movies I have chosen to research, these movies include; Avatar, World War Z, 300, War of the planet of the apes, Casino Royale and American Sniper. The listed movies were chosen based on my personal preference for movies whilst taking into consideration the responses that the audience has given regarding the film, I have aimed to choose films within the 15-18 age rating mark to explore to a greater extent of how violence affects narrative in the action movie genre. This essay will analyse how greatly violence affects narrative systems in action films, with particular focus on – ‘Avatar (2009), World War Z (2013), 300 (2006), War of the planet of the apes (2017), Casino Royale (2006) and American Sniper (2014), ’ concentrating on how these titles challenge or reinforce particular action narrative conventions. Regarding the aspect of time in the film, it was Todorov who stated that – â€Å"All stories are based on a change from equilibrium (where everything is in order) to disequilibrium (chaos).† This can be applied when watching Avatar, James Cameron directs the movie with the assumption that the audience knows that everything is in order. Set in the distant future where technology has vastly advanced, a cripple played by Sam Worthington gets the opportunity to explore a ‘new world’ known as Pandora to further learn about their species known as the Navie. James Cameron reinforces Todorov’s theory through Avatar. He does this through Jake Sully (Sam Worthington) who starts learning about the Navie, gradually bonding with their kind, only to be stopped by his commander who seeks to attack the Navie for their land which holds expensive materials, resulting in the Navie to lose their trust for Jake Sully. However, Cameron then challenges this theory by having Jake Sully fill the position of the hero in the film entitling him with the role of a proper protagonist in an action movie as he goes against his commander to save the Navie and the woman he has fallen in love with. The importance of time for narrative can be highlighted by the view that – â€Å"Time can be subverted, altering the story and its effect on the viewer.† This can be applied to Avatar as the main protagonist in the movie enters Pandora through a machine which morphs the conscience from his body into an alternative Avatar body. These scenes are shown to the audience multiple times within the film and are presented in the form of some sort of dream to make a clear distinction between the time in the ‘real world’ and Pandora. Regarding the plot and story of Avatar James Cameron uses violence to clearly illustrate to the audience the binary oppositions within the film, using different genres of music when a ‘good’ or ‘bad’ character appears on the screen as well as using non-diegetic voice-overs of Jake Sully with the intentions of making him appear as an ‘underdog’ sort of character who is rising up and finding a purpose in his life. In summation to this, different shot types are used to highlight certain characters dominance – evidence of this can be seen from when Jake Sully is presented in a worm’s eye view type of shot despite him being a cripple, a sense of nobility is being expressed. It was Jacques Derrida that stated that â€Å"binary pairs were never equal.† He further went on to claim that within any particular culture, one ‘side’ of each binary pair tended to be valued or judged in a more privileged light. This idea is con firmed heavily in Avatar painting the Navie to be a good force and the military/scientists to be the enemy attempting to steal the Na vie’s land and even kill them if they stand in their way. Whether or not violence is important for narrative in the action movie genre, can be further answered by decomposing the movie; World War Z. Marc Forster places Gerry Lane high up on a podium presenting him to the audience to be a strong, brave and heroic protagonist, this is done through the use of backstory given to his character in the movie. Using the information that Forster gives the audience we learn that Lane has a motive for what he is doing and why he is doing it- we as an audience come to learn that he wants to protect his family and the other people close to him all whilst bearing the hopes of the world on his shoulders. With further reference to the plot as a narrative, Bordwell and Thompson stated; â€Å"All we have before us is the plot – the arrangement of material in the film as it stands. We create the story in our minds on the basis of cues in the plot.† This is reinforced in World War Z as it follows a linear narrative but leaves the option open for an open ending in which the audience can ponder on a possible ending for the movie, various situations in the movie allow the audience to do this; the idea is further supported through violence as seen in the opening three minutes of the film where multiple disasters are presented to the audience through a ‘news broadcast’ format, which is used for authenticity and to give the viewer an idea of what the current state of the world is. An example of this further being enforced can be seen during the first action scene that we see in the film, a state of confusion and uneasiness is created by Lane and his wife’s reaction to hearing about the – â€Å"sudden outbreak of rabies† on the radio, this develops into a state of panic when we begin to see everyone running to safety; trampling over people and even going as far as to run over people. The unintentional violence shown here is purposefully added by Foster in an attempt to connote the level of threat in the current situation and how serious it is. In summation to this, this scene can be compared to a later action scene in the film which takes place in Jerusalem; in this case the audience is left to wonder what the outcome of the battle is going to be, Forster doesn’t give the audience an opportunity to easily pick an ending of the scene; he structures the film in a way which presents the antagonists in a superior sense – as seen from the many scenes where the antagonist have the upper hand on the main characters in the film. The scene in Jerusalem shows an injured soldier on the floor with a wound on her arm is an example of this, Lane is presented to the audience in an over the shoulder shot moaning in pain whilst he attempts to console her. Despite this the audience could have conflicting ideas for who would prevail due to characters such as Lane in the film being presented as heroes as seen from his elevated status when he is consoling the soldier, making him the dominant figure in that particular shot. In summation to this, the various triumphs and escapes that the characters make the infected humans support the protagonists prevailing. With regards to the narrative that violence adds in these two scenes, it is clear that violence is important when taking into account the audience’s interpretation of how the next scene will turn out, Foster uses violence as a key element throughout the film to leave the audience sceptical as to what is going to happen to Lane next. In conclusion, I believe that it can be seen from the evidence above that violence is important for narrative in the action movie genre, supporting this would be how violence presents the audience with a binary opposition which ultimately sets the story and plot of the film; violence also reveal certain character traits to the audience and presents them in various lights. However, it can also true that violence is not the key element for narrative in the action movie genre.

Greenwich Mean Time vs. Coordinated Universal Time

Greenwich Mean Time vs. Coordinated Universal Time By the mid-nineteenth century, Greenwich Mean Time (GMT) had been established as the primary reference time zone for the British Empire and for much of the world. GMT is based on the line of longitude running through the Greenwich Observatory located in the suburbs of London. GMT, as the mean within its name, would indicate, represented the time zone of a hypothetically average day at Greenwich. GMT disregarded the fluctuations in the normal earth-sun interaction. Thus, noon GMT represented the average noon at Greenwich throughout the year. Over time, time zones became established based on GMT as being x number of hours ahead or behind GMT. Interestingly, the clock began at noon under GMT so noon was represented by zero hours. UTC As more sophisticated time pieces became available to scientists, the need for a new international time standard became apparent. Atomic clocks did not need to keep time based on the average solar time at a particular location because they were very, very accurate. In addition, it became understood that due to the irregularity of the earth and the suns movements, the exact time needed to be modified occasionally through the use of leap seconds. With this precise accuracy of time, UTC was born. UTC, which stands for Coordinated Universal Time in English and Temps universel coordonnà © in French, was abbreviated UTC as a compromise between CUT and TUC in English and French, respectively. UTC, while based on zero degrees longitude, which passes through the Greenwich Observatory, is based on atomic time and includes leap seconds as they are added to our clock every so often. UTC was used beginning in the mid-twentieth century but became the official standard of world time on January 1, 1972. UTC is 24-hour time, which begins at 0:00 at midnight. 12:00 is noon, 13:00 is 1 p.m., 14:00 is 2 p.m. and so on until 23:59, which is 11:59 p.m. Time zones today are a certain number of hours or hours and minutes behind or ahead of UTC. UTC is also known as Zulu time in the world of aviation. When European Summer Time is not in effect, UTC matches the time zone of the United Kingdom. Today, it is most appropriate to use and refer to time based on UTC and not on GMT.

Inertia and the Laws of Motion

Inertia and the Laws of Motion Inertia is the name for the tendency of an object in motion to remain in motion, or an object at rest to remain at rest  unless acted upon by a force. This concept was quantified in Newtons First Law of Motion. The word inertia came from the Latin word iners, which means idle or lazy and was first used by Johannes Kepler. Inertia and Mass Inertia is a quality of all objects made of matter that possess mass. They keep doing what they are doing until a force changes their speed or direction. A ball sitting still on a table wont start rolling around unless something pushes on it, be it your hand, a gust of air, or vibrations from the surface of the table. If you tossed a ball in the frictionless vacuum of space, it would travel on at the same speed and direction forever unless acted on by gravity or another force such as a collision. Volker Mà ¶hrke / Getty Images Mass is a measure of inertia. Objects of higher mass resist changes in motion more than objects of lower mass. A more massive ball, such as one made of lead, will take more of a push to start it rolling. A styrofoam ball of the same size but low mass may be set in motion by a puff of air. Theories of Motion From Aristotle to Galileo In everyday life, we see rolling balls come to rest. But they do so because they are acted on by force of gravity and from the effects of friction and air resistance. Because that is what we observe, for many centuries Western thought followed the theory of Aristotle, who said that moving objects would eventually come to rest and needed continued force to keep them in motion. In the seventeenth century, Galileo experimented with rolling balls on inclined planes. He discovered that as friction was reduced, balls rolled down an inclined plane attained almost the same height rolling back up an opposing plane. He reasoned that if there were no friction, they would roll down an incline and then keep rolling on a horizontal surface forever. It wasnt something innate in the ball that caused it to stop rolling; it was contact with the surface. Newtons First Law of Motion and Inertia Isaac Newton developed the principles shown in Galileos observations into his first law of motion. It takes a force to stop the ball from continuing to roll once it is set in motion. It takes a force to change its speed and direction. It doesnt need a force to continue moving at the same speed in the same direction. The first law of motion is often referred to as the law of inertia. This law applies to an inertial reference frame. Corollary 5 of Newtons Principia says: The motions of bodies included in a given space are the same among themselves, whether that space is at rest or moves uniformly forwards in a straight line without circular motion. In this way, if you drop a ball on a moving train that is not accelerating, you will see the ball fall straight downward, as you would on a train that was not moving.

Assessing Theories and Practices in Recruitment, Selection and Essay

Assessing Theories and Practices in Recruitment, Selection and Diversity Management - Essay Example Every human resource department desires to be able to hire the best fitting person for the job in terms of skills, attitude and personality. Thus companies find ways to develop and benchmark among various "good practices" in their recruitment and selection processes. This paper lays down some good practices and analyses underlying processes and theories focusing on the management of recruitment and selection programs. The paper also discusses diversity management and its effects on the program's outcomes. Companies continuously strategise to determine their competitive edge in the business world. Likewise, they need to continuously analyse the strength of their workforce including the gaps between supply and demand of available workers. Planning is a proactive move and a strategic activity that enables company to identify the needed critical skills and forecast the activities that will generate these needed critical skills. (Revelle 1995) Through the strategic workforce planning, companies will be armed with the information: what the company needs and what people will be available to meet those needs. Recruitment Processes "Garbage in - garbage out." (Armstrong 2006) Many problems in the workplace may be traced from poor workforce planning and poor implementation of the recruitment and selection programs. Many businesses, particularly those without properly installed human resource departments are guilty of these and they realize it too late when they already have unproductive and troublesome employees in their midst. Recruitment is one major function of the human resource department. It is the process of "finding the right people for the right job". (McNamara 1997) The Selection process is usually tagged along with the recruitment process together because of the interrelatedness of the functions. The recruitment aspect focuses on locating and inviting the prospective applicants. Dr. Paul R. Bernthal of Development Dimensions International gave the definition of recruitment as "the process of identifying and attracting a group of potential candidates from within and outside the organization to evaluate for employment." (2002) Once these candidates are identified then employment selection process begins. A research conducted in 2002 by Dr. Bernthal on 573 member companies of the Electronic Recruiting Exchange made important findings on best practices and trends in recruitment as well as in selection. (2002) Among the findings were that companies tend to hire external than internal candidates. This is true to mid or senior level positions. It is understandable for companies to prefer external candidates because many companies need additional skills and new breeds in their workforce. After thorough inventory of employees' skills, most companies find need for additional skills into the company thus they most often prefer to hire new employees than fill vacant positions with those from the ranks. Another finding from the DDI research was that most organizations are agreeable to increase their funds for human resource development particularly in their recruitment and selection programs. About 33% of human resource funds is allocated for recruitment and about 18% for selection processes. (Bernthal 2002) Many companies are already conscious of the importance of proper recruitment proces
