Mind Games Essay

The goal of argumentative writing is to persuade the audience that their ideas are valid or more valid then other authors. Greek philosopher and writer, Aristotle, divided persuasion into three sections: Ethos, Pathos, and Logos. These persuasion guidelines give readers a sense of credibility, emotion, and reasoning. Ethos is associated with credibility or ethical appeal (Ch. 3, Ethos). Does the author portray the characters as people who are worthy of respect? One problem with argumentation is the ability to impress the reader. By making the character someone that is respected and therefore likable the reader is more interested in the work. An example of this would be a doctor, lawyer, or veteran. Even though all of these jobs serve our community in different ways, they are all respected by society. Another example of logos that the book noted was â€Å"If a company is well known, liked, and respected, that reputation will contribute to it’s persuasive power (Ruszkiewicz, 56).† If its character is problematic in any respect, it may have to use argument to reshape an audience’s perception (Ruszkiewicz, 56). Authors will also use ethos from personal experience. Writer and activist Terry Williams attacks those who poisoned the Utah deserts with nuclear radiation (Williams, 58) Terry Williams is a women worth listening to because she has lived with the nuclear peril. These are just some of the ways authors can show authority. Pathos is emotional and persuades by appealing to the reader’s emotions (Ch. 2, Pathos). Language choice affects the audience’s response, and emotional appeal can enhance an argument. The book gives an example of a teacher telling her students that she is legally blind (Kleege, 45). While reading this example, you are probably envisioning yourself sitting in the classroom in shock from what you just heard. When someone gives you information about them or reveals a truth, as the listener, you are taking in everything the speaker is saying; while relating that to every circumstance you can recall. As a student sitting in her classroom, you are thinking about your personal experience with another blind person and forming your own opinion on this person. This example plays in on your emotional side because from the very first day you are aware of your teacher’s disability. Pathos does not always have to be sad; it can also be humorous. Writers can use humor to lighten up the mood and make the reader more comfortable with an argument. The example from Dave Barry (Barry, 49) touches on the idea that men do not need to read the manual but often times make mistakes. This particular example is saying men think they know all, but in reality, they still need help. Logos persuades by the use of reasoning (Ch. 4, Logos). The heart of the argument is presenting the reader with reasons. Effective persuasion can help you back up your claims as well as give proof to your argument. Aristotle divided argumentative writing into facts and reason (Ruszkiewicz, 69). He used what we call hard evidence and reason or common sense (Ruszkiewicz, 69). The book gave an example of U.S. ambassador to the UN asking ambassador Zorin if he had â€Å"placed or is placing medium and intermediate range missiles and sites in Cuba (Ruszkiewicz, 70)?† Representatives allowed him to ask this question because he had hard evidence of spy photographs to prove his claim (Ruszkiewicz). Logos can be shown through text also. By reprinting a single page from a document, you have proof from years past. The example in the book stated the connection between statements and proofs was credible. The article talked about gun ownership (Lindgren, 75). Logos is important in argumentative writing because readers like to have more then one credible source. As a college student, I would write an article on local colleges and universities providing more activities to 18-20 year old students. This article would show ethos because I am a nineteen-year-old local college student. This topic would show pathos because I am appealing to local people that might be affected by drunken college students driving on the roads. I would use the local police records to provide logos to persuade my readers. Another college student might write an essay to persuade local governments to allow 18-21 year old students into the bars. It would be important for the writer to be a responsible college student to establish ethos. The student could argue that this policy would allow underage students to be designated drivers for the legalized students. This would demonstrate pathos. The writer could use local traffic records and news stories to create logos. When an author writes a good rhetorical essay it is similar to a sales representative selling a product. The writer is selling their idea to the public just like the sales rep is selling their product. It will be important for both of them to establish ethos with their audience to make credible representations. They will both use pathos to interest a person in their product or idea. It is also important for both of them to use logos to back up the claims they are making. A sales rep will be rewarded with a commission, and a successful write will be rewarded with future writing assignments. Works cited Ruszkiewicz, Andrea A. Lunsford John J. Everything’s an argument.

Literacy and People Essay

â€Å"Literacy† is an often discussed topic. Be able to read and write is not as simple as it looks; literacy is one of important communication skills in today world. According to the United Nations Educational, Scientific and Cultural Organization, â€Å"Literacy† means â€Å"ability to identify, understand, interpret, create, communicate and compute, using printed and written materials associated with varying contexts. Literacy involves a continuum of learning in enabling individuals to achieve their goals, to develop their knowledge and potential, and to participate fully in their community and wider society. † In other words, a person has the ability to understand and exchange of opinions and views in a society, and thus participate in this society. So if literacy is so important to everyone, then how does the reality look like? We start at very early years to learn reading and writing, so we forget that reading and writing actually are a fairly complex skill, it takes years to learn and memorize. Even in the highest level of civilization country, such as US, the proportion of literate adults has never reached 100%. According to an article â€Å"The Human Cost of an Illiterate Society† by Jonathan Kozol, there are 60 million people that are â€Å"functionally illiterate† in 1980, and he demonstrate an accurate portrait of the life illiterates live on a day-to-day basis and feel miserable. Even literate people, there are only a small number of people with a high level of reading and writing skills. In human history, the literacy was a privilege. In â€Å"Learning to Read and Write† by Frederick Douglass and â€Å"Learning to Read† by Malcolm X. They both demonstrate how important the basic reading and writing skills are and people could use it as a simple tools to impact people and auto gnosis and social change. To be literacy also is very important to people who want to participate in their society and make them life easier. In â€Å"The Joy of Reading and Writing: Superman and Me† by Sherman Alexei and â€Å"Mother Tongue† by Amy Tan. Both of their stories shows us how reading and writing provide they better future, and how difficult could be without the knowledge of literacy. So I truly believe in knowledge could change our future, and help us to build the abilities of adopting the society. And more importantly, we absorb and reveal those knowledge need to through by the reading and writing. People has their own future, that is undoubtable; but how to clarify the future is a problem that confusing many of us. Language gives a great contribution to solve this problem. Since getting language can allow people learn things and gain knowledge, it helps people know more of what our society is about and what is good for them. With these experiences, people will have a better idea of what kind of future they want and create their own dream. Sometimes, this can change a person’s life just like what Malcolm X said in his article â€Å"Learning to read†: â€Å"I knew right there in prison that reading had changed forever the course of my life. As I see it today, the ability to read awoke inside me some long dormant craving to be mentally alive. † In other words, the knowledge form books could impact a person from inside out. Therefore, language can help people adopt the society by showing them their future. Another ability that language can show people is the ability to fight and defense. People usually use their fists, club, or even gun as a weapon to hurt others, but in modern society with police department to stop these physical violations, what can be better than use the words to beat people. By learning knowledge, language through receive language, people also learn that these things can use to fight and defend in real life. With leaving an indelible memory in one’s mind, apparently, it is more powerful than healable body damage. Many people include Richard Wright realize its power, Richard even has some words in his essay â€Å"The Library Card† said: â€Å"Yes, this man was fighting, fighting with words. He was using words as a weapon, using them as one would use a club. † So, this is another useful effect that language brings to people, protect and fight back. There is another thing people gain form language can help them feel better in the society, which is discovery the truth. This skill, or ability, can allow people ignore the interferences on the way to success, to achieve a goal, create own future. Throughout the history, many brilliant people fail just because they were direct to a wrong way. Why they never know that? Because they were uneducated or instill something wrong, they were expected to fail. Situation in the past has shown in Sherman Alexei’s â€Å"The Joy of Reading and Writing: Superman and Me† described the difficulties that Indian kids were facing: â€Å"As Indian children, we were expected to fail in the non-Indian world. † Obviously, language provides people the ability to dig out the real truth behind illusion. Nowadays society, many people are confusing about their futures. Literacy gives a great contribution to solve this problem. At first, literacy can help people adopt the society by showing them their future. Secondly, literacy can show people are the ability to fight and defense themselves. Finally, language provides people the ability to dig out the real truth behind illusion. Literacy is important in keeping you safe and allowing you to learn and grow to better yourself. 50 Essays Bedford/St. Martin’s, 75 Arlingto Street, Boston, MA 02116 Nations Educational, Scientific and Cultural Organization http://en. wikipedia. org/wiki/Literacy.

Operations Management Exam Essay Example | Topics and Well Written Essays - 2500 words

Operations Management Exam - Essay Example A great deal of focus is on efficiency and effectiveness of processes. Therefore, operations management often includes substantial measurement and analysis of internal processes. Ultimately, the nature of how operations management is carried out in an organization depends very much on the nature of products or services in the organization, for example, retail, manufacturing, wholesale, etc.It is about the transformation of production and operational inputs into "outputs" that, when distributed, meet the needs of customers. Operations Management deals with the design and management of products, processes, services and supply chains. It considers the acquisition, development, and utilization of resources that firms need to deliver the goods and services their clients want. Operation Management ranges from strategic to tactical and operational levels. Representative strategic issues include determining the size and location of manufacturing plants, deciding the structure of service or telecommunications networks, and designing technology supply chains. Tactical issues include plant layout and structure, project management methods, and equipment selection and replacement. Operational issues include production scheduling and control, inventory management, quality control and inspection, traffic and materials handling, and equipment maintenance policies. In a production unit (e.g. ... Capacity management is responsible for ensuring that infrastructure resources are well geared up to satisfy planned business needs effectively. The desired goal for capacity management is to provide a service that is proactive rather than reactive in nature. Measuring capacity Capacity, being the ability to produce work in a given time, must be measured in the unit of work. For example, consider a domestic air conditioning units factory that has a capacity of 10,000 " machine hours" in each 40 hour week. This factory should be capable of producing 10,000 "standard hours of work" during a 40-hour week. The actual volume of product that the factory can produce will depend on: -The amount of work involved in production (e.g. does a product require 1, 5, 10 standard hours -Any additional time required in production (e.g. machine set-up, maintenance) -The productivity or effectiveness of the factory. The major work components of capacity management are: Performance management is a continuous improvement process that examines application and system performance and analyze them for possible improvements, analyzes the costs and requirements, commissions the corrective work, then measures and reports the results. An effective performance management team can reclaim infrastructure capacity by finding ways to improve the way applications consume resources. Workload management uses data from performance monitoring tools to separate resource usage by business process rather than individual increments of usage on a particular infrastructure component. The goal is to address capacity needs on a business process basis. Since some business processes have downstream effects on other

Martin Luther and the 95 Theses Essay Example | Topics and Well Written Essays - 1000 words

Martin Luther and the 95 Theses - Essay Example The darkness that spread across the world with as the shadow of the Papacy's unremitting reluctance to accept scientific progression turned western civilization from the cradle of knowledge into a place where minds like Aristotle and Galileo were placed into submission behind adherence to religious beliefs at odds with facts and evidence. The importance of Martin Luther to contemporary civilization therefore rests upon the genuinely frightening concept of what the world might look like had he not hammered a nail into the unquestioned authority of the Church. The spark that lit the wick that would result in the explosion known as the Protestant Reformation can be traced back to a single spring day in 1517. What occurred on the day was nothing that had not been duplicated countless times before and after; the manner in which forces converged to implicate the actions of that day with an importance beyond their scope may be taken according to one's own perspective as either a sign of God working in His mysterious ways or as an example of the mystery of social evolution. The entirety of the Protestant Reformation is conventionally attributed to the work of Martin Luther, but the impetus behind why Luther was motivated to nail the 95 theses to the church wall is as mysterious to most people as the causes behind why that spring day in 1517 was so unique. Although Luther may be the figure of vital importance in the story of the Protestant Reformation, he was preceded by other figures that acted as the charge behind his radical awakening. The least well known, but perhaps most influential, figure in the story of Luther's awakening was a Dominican friar named Johann Tetzel. Tetzel began selling indulgences along the border of Saxony. Indulgences were nothing more than pieces of paper in reality, but within the universe of the Catholic Church they represented a promise of the remission of the penance placed upon a sinner by his confessor. The sale of indulgences had spread quickly during the early decades of the 1600s and friars such as Tetzel were anything but an uncommon sight (Mullett 68). What set Tetzel apart from the rest that raised the ire of Martin Luther and set him upon a course that would revolutionize western civilization Another important figure that remains mostly in the shadows on the road leading to the nailing of the 99 Theses is Albert of Hohenzollern. Albert was the younger sibling of the elector of Brandenburg who had gotten himself into debt. By 1513 Albert was paying enormous amounts of cash in order to acquire dispensations from Rome to retain his holdings several bishoprics. At age 23, Albert was not legally old enough to assume the position of bishop in these areas, but that did not stop him from setting his eye on the see of Mainz when the position became vacant. Albert was successfully elected to the position despite the realization that in doing so he would be owing even more money to the Papacy. In order to meet his increasing debt, Albert arranged for financing with the Fuggers Bank before arranging a deal with Leo X in which the pope proclaimed an indulgence in Albert's territories based on the mutual understanding that fully half the money raised would go toward building St. Peter 's Basilica in Rome. The other half would, of course, go straight to Fuggers by way of Albert (Waibel 40) . All

Aggregate demand and its components Essay Example | Topics and Well Written Essays - 1250 words

Aggregate demand and its components - Essay Example This essay is an attempt to figure out the constituents of aggregate demand and how they interact to determine the national income. The main focus of this essay is Keynesian economics and how aggregate demand is determined in Keynesian economics. A basis proposition of Keynesian theory is that the equilibrium level of income and output depends on the economy’s aggregate spending for output. If aggregate spending is excessive, it results in inflation. My goal in this essay is to figure out how national income is determined through aggregate demand and what is the impact of aggregate demand on other major macro economic variables. Introduction In national income determination, aggregate demand plays a vital role. The first major objective of any economy is to increase and sustain its national income, an analysis of aggregate demand is very important. By controlling the aggregate demand, you can control the major economic variables. Aggregate demand is the total demand in an econ omy for all the goods and services produced. It consists of : Consumption expenditure, Investment expenditure Government expenditure Net export Aggregate demand = C+ I+ G+ (X-M) The following sections analysis each of these variables in detail: Consumption Expenditure Consumption expenditure depends on the real income of the house hold. An increase in the real income of the household leads to an increase in the consumption expenditure and a reduction in the real income of the household results in a reduction in consumption expenditure. ... tion expenditure, Keynes gave priority to consumption function which is a mathematical function showing the relationship between consumption expenditure and income. As income increases, people set aside a portion of their income for their future needs. In other words, as income increases, savings also increase. Even though the consumption increases as the income increase, the rate of increase is less. But, as the income increases, the savings increase at an increasing rate. It means, the individual set aside a larger portion of his income for savings and a smaller portion of consumption. Keynes considered consumption function as constant in the short term. The change in consumption is always greater than zero and less than one. It means, whenever there is a change in income, people won’t spent the whole amount on consumption. Investment Expenditure Keynes gave more importance to investment demand than consumption demand. The investment demand depends on two things: 1) Marginal efficiency of capital 2) Rate of interest Out of these two, rate of interest is usually stable in the short run (changes based on the policy of the central bank). So the investment demand depends largely on marginal efficiency of capital. The marginal efficiency of capital means the expected rate of profit that the investor hopes to make from the investment in capital assets. The marginal efficiency of capital depends up on the replacement cost of capital goods and profit expectations of investors. As there is no replacement in the short run, the investment in short run mainly depends on profit expectations. To increase national income and employment, government should take those measures which increase investment. So, the investment demand depends on the marginal efficiency of capital and

Case Study -- Report Essay Example | Topics and Well Written Essays - 2750 words

Case Study -- Report - Essay Example Finally, a link has been brought out to bring out the relationship between training and other aspects of human resource management. Most importantly, training was found to have a direct relationship with motivation of employees. Training is effective in identifying the requirements in employees’ performance and by motivating him to do so. The project is primarily based on secondary research. Finally the project recommends the implementation of different techniques of training, namely on-job and off-job training. In this context, both the advantages and drawbacks are discussed at length. Introduction This project aims to bring forth the importance to training and development programs in organisations for uplifting individual as well as organisational performance. The Sing Tel Optus case study is chosen for the purpose of identifying the above requirements. The case speaks of a new training and development program introduced by the company to train its employees. This training i s not only meant to enhance the existing skills of the staff, but is also aimed at rewarding the employees for successful completion of the program. The main purpose of this case study is to bring out the impacts that this program has had on the employees and the organisation. In this context, the project tries to discuss how the program adds to the skills and productivity of the employees. It brings out the results that the program has generated in uplifting the market image of the company as being a favourable employer. The different kinds of training methods, namely, on-the-job and off-the-job training methods have been discussed. The advantages and drawbacks of each method have been discussed. This has been done in the context of Sing Tel Opus’s training strategies and the benefits and loopholes of the same. A relationship between such training and development strategies and the various human resource management practices have been brought to focus in the project. Concept s like motivation and performance appraisals have a direct relation with the system of training and development in organisations. The interdependencies between these concepts have been highlighted in the project. Importance of Training and Development (T&D) There is a common phrase said by Confusius in 5th century BC, â€Å"Give a person a fish and you feed him for a day. Teach a person to fish and you feed him for a lifetime† is still valid (McClelland, 2002, p.7). In the early days, businesses considered the workers similar to other factors of production. Therefore, the main aim was to get maximum utilisation of the labour force. However, with time the corporate people realised that human resource is quite different from the other resources. To improve the productivity of this particular resource, it should be trained. This through process motivated businesses to plan different types of training and develop programmes for its human resource so that it can acquire required s kill and knowledge to fulfil the job responsibility in best possible manner. Scholars such as Knowles (1989), Noe (2008) & Blanchard and Thacker (2007) pointed out that the motivation to learn is influenced by two major components; these are

Global warming Essay Example | Topics and Well Written Essays - 500 words - 2

Global warming - Essay Example With the influx of urbanization, pollution from engines, industries, and companies needs to be stringently regulated. Such has become an advocacy for Intergovern ­mental Panel on Climate Change (IPCC), World Meteorological Organisation (WMO), and the United Na ­tions Environment Programme (UNEP) since 1988 with civil society around the globe (IPCC, 2007). The issue deserved serious concern as global temperature increased from 3 ° to 5 ° C – and might reached at 5.4 ° to 9 ° Fahrenheit in 2100. The sea level has also risen at 25 meters and is projected to reach 82† by the year 2100 (IPCC, 2007).    The rise of global temperatures brought along some drastic changes in land and oceans as thermal expands at the ocean and the rapid melting of polar and Antarctic regions (IPCC, 2007; Craven, 2012). Ecologists likewise observed that precipitation patterns are changing with disaster’s increase of numbers and intensities. Experts posit that the erratic increase of frequency, duration, and intensity of climatic outburst caused so much flooding, prolonged drought season, severe heat waves, and changes in weather patterns (IPCC, 2007; Craven, 2012). The global warming cause negative impact to agriculture too as yields became poor; more glacial retreat, reduced summer period; and brought extinction of some species (IPCC, 2007; Craven, 2012). Health experts also argued that global warming also espoused malaria and other diseases in areas where these have been quelled before (IPCC, 2007). Global warming is a consequence of both manmade actions and astronomical developments influencing the earth’s surface (Craven, 2012). In the last decades, people have increasingly devastated ecology with pollution, logging, mining, and other resource related extraction. This is further aggravated with the recent phenomenon when the sun reached its ripening period thus producing some C-flares,

Police Technological Advancements Research Paper

Police Technological Advancements - Research Paper Example These innovations provide much comfort and to a great extent security to the average consumer. However, despite the valuable assistance that such developments have provided to us, these techno upgrades have also created opportunities for criminals to flourish even more. Cyber crimes abound and identity theft has risen. Here, thieves do not need to hold you at gun point and steal from you, they just need to â€Å"pretend† they are you and let you take the fall for the expenses they will incur in your behalf (Identity Theft & Credit Fraud). Criminals have also found ingenious ways of going around various technological check points such as surgically implanting heroine on puppies. With the advances in technology comes the improvement in the way criminals think and act thereby necessitating that law enforcers up the ante a little bit so as to be one step ahead or at par with these culprits. Police work is a very dangerous business and these men and women have to contend with the r eality of danger each day. But, unlike in the military, policemen are much more inclined to public service and safety hence the need to take in rather than take out the criminals. This reality puts the everyday cop on the block in a quandary as they have to strictly adhere to the sanctity of human life thereby limiting the use of force unless it is severely necessary whereas they are faced with entities that seem to have no regards whatsoever to these rights (OHCHR Human Rights Standards and Practice for the Police ). Thus, to ensure safety of the arresting officer as well as to respect and enforce human rights and combat the increasing sophistication of offenders, police forces around the world have commissioned technology to aide them in ensuring public safety. Technological Advances in Detection and Weaponry Aerial Sentinel – the MQ-1 Predator Most people would think that police work is about arresting criminals. However, although it is the part that is mostly reported and where they are most exposed to danger, arresting is only a small part of police work. A very important aspect of doing police work is in safekeeping the public. This involves various forms of reconnaissance to track criminals and secure evidence for prosecution. A big boost in doing this police work is the utilization of Unmanned Aerial Vehicles (UAV’s) to help enforces track, pinpoint and ultimately apprehend offenders. After a very successful stint in the armed forces, the UAV has also started a career in police work. Very recently, it has been reported that unmanned UAV’s have taken part in the war on drugs in Mexico wherein the US assisted Mexican authorities in dismantling drug cartels by providing valuable information through their Predators (BBC News). Since respect for territorial sovereignty is key in the cooperative efforts, only the Predator has been used since it is the unarmed variant of these UAV’s. However, though without firepower, this machine is armed to the teeth with state of the art reconnaissance systems and is able to provide up to date images anytime and any day (General Atomics Aeronautical). Stun Guns As mentioned, the nature of police work is to take in rather than take out a target. With the rising global concern on human rights, police forces

Evolution Questions Assignment Example | Topics and Well Written Essays - 2500 words

Evolution Questions - Assignment Example When meiosis occurs, genes are segregated at random and events such as crossing over can occur, which causes increased genetic variation. In larger populations, the allelic combinations typically stay stable over time. However, in smaller populations, any type of variation or production of one gene over another due to chance can have a large change in the gene pool frequencies. The most useful way to think about this concept is in terms of the Hardy Weinberg Equation, which is a quadratic formula that calculates the genetic frequencies of the homozygous dominant, homozygous recessive, and heterozygous expressions. The Hardy Weinberg Equation uses the letters P and Q in order to addresses the alleles for a population with homozygous dominant being p2, homozygous recessive being q2, and heterozygous being pq. Normally, in a standard population and statistically valid population, the ratios would be the same. Like stated above there are multiple factors, which can then affect the ratio of these allelic frequencies. Some of the organisms may survive due to supremacy of the traits they expressed or the randomness of gamete formation may lead to an unproportional expression in traits. For example, lets consider a population which has allelic frequencies of p=0.3 and q=0.7. ... This is because a statistical change in allelic frequencies in a smaller population due to chance has a larger and more significant effect because the population, N, is smaller. Therefore, the effect size is larger. The reason that it is not as powerful in populations with a large N value is because it is thought that the chance of one allelic combination being produced over the other is negligible, therefore they cancel out which shows that there is no real resulting chance in the frequencies of the gene pool. DNA replication is a process, which is ongoing at every moment in every organism. It is important in order to ensure that the structure of the genetic code remains viable for reproduction, however the code becomes more disrupted every time that it is replicated. These mistakes are mutations, which occur in the replication of DNA can cause either desirable or undesirable traits to form. This is one of the basis in which evolution is thought to occur. Different types of mutation s have different effects on evolution. Replacement mutations are much lower than substitution mutations. These are thought to effect neutral genes, which remain structurally similar over time. Substitution mutations are thought to happen in genes that are dynamic and are quick changing in that this is the main mutation, which promotes the most genetic variation. Conservation biology is the field of biology that is directed specifically at understanding and protecting the biodiversity of the Earth. Understanding the role and relationship of species in their habitats and ecosystems does this. Specifically, Templeton was concerned with the human activity, which was having an affect on genetic variation of the collared lizards in the

Identity Research Paper Essay Example for Free

Identity Research Paper Essay Malcolm Rivers from the movie â€Å"Identity† has been diagnosed as a mentally ill patient with Dissociative Identity Disorder. This disorder is basically another name for a multiple personality disorder. The disorder is usually caused by severe trauma, emotional or physical, that causes people to create â€Å"multiple personalities† so that they can deal with certain situations. They usually have the inability to recall important information and have blackouts. Lastly, they have confusion of personal identity for an assumption of a new identity. The patient, Malcolm Rivers has committed several vicious murders and is waiting for execution. There is a journal that Rivers has explaining why he really committed the murders of all these people at a motel. His psychiatrist, Doctor Malick, tries to explain to the Judge who wants to have Rivers executed that he wasn’t responsible for the murders. The argument Dr. Malick made for it not being Malcolm Rivers fault is that it was one of his personalities because in his journal he has written down personal and private thoughts of several different people, which is a symptom of Dissociative Identity Disorder. Doctor Malick took Malcolm Rivers in front of the Judge and started questioning him to prove that he has multiple personalities. When he was questioning him though, he wasn’t Malcolm Rivers; he was â€Å"Ed†, the limo driver from the motel that everyone was getting murdered at. â€Å"Ed† keeps having these blackouts and this one blackout led him into the courtroom with Malick and the judge. â€Å"Ed† tells them what was happening at the motel and how it was bizarre that everyone was getting murdered and bodies were disappearing. In response to Malcolm Rivers or â€Å"Ed’s† story, Malick tells â€Å"Ed† about how he is really Malcolm Rivers. Rivers’ traumatic childhood has a strong effect on him, which made his personality fracture into different personalities. He remembers his mom as being â€Å"promiscuous† depending on whom she brought home he may also have been beaten as a child, and the disorder is caused by both mental and physical trauma. â€Å"Ed† found this really confusing, so Malick gave him a mirror that way he realized that he was just another personality. Malick also made another assumption that â€Å"Ed† and all the other people at the motel had the same birthdays. He told â€Å"Ed† that one of his fellow personalities is the one responsible for the murders, so once that personality dies, Malcolm Rivers won’t have to executed because he will be harmless. â€Å"Ed† thought that he finally identified the personality responsible for all of the murders. When he tried to kill it, both the personality and â€Å"Ed† die at the motel. Malick convinced the judge that the homicide identity is dead and Rivers should be harmless. Rivers was let off the execution and put into a mental asylum. Little did he know he actually killed the wrong personality, it was really Timmy, a little boy, the murdered everyone and set up their deaths. In Rivers’ head it showed Timmy was the one always watching the deaths of everyone, but he was so quiet no one suspected him. Timmy’s personality eventually dominated Rivers body and strangles Malick that crashes the truck going to the mental asylum. There are both positive and negative messages the movie gives the public about people with this disorder. One negative message it can give off is the impression that people with this disorder are dangerous murders, not all people with multiple personalities are dangerous or destructive. There are actually only a few cases that people with multiple personalities have criminal behavior. Another negative message is that it shows criminals can get away with a crime and be let off an execution if you have multiple personalities, a criminal does not get out of it that easily, they need to go through a long process of multiple professional physicians to prove they are criminally insane. Lastly, the personality ended up dominating Malcolm Rivers body in the end, so it can give off the idea to the public that this disorder can not be cured when it can. There are also positive messages that the movie gives off to the public that watches it. For one, it successfully shows the symptoms of a person with dissociative identity disorder. It can also give people a good idea that if they suspect someone they know has this disorder; you should get them to keep a diary to get down their personal thoughts so you can tell if they have it. Lastly, it shows that having a traumatic childhood can affect a person. That is a positive message because it can make people want to be better parents to their children after seeing what a bad childhood can do to someone. The journal article on dissociative identity disorder shows the four dominant approaches to understanding the disorder: childhood trauma and media influences. The posttraumatic model of dissociative identity disorder shows that the disorder is a defensive response that results naturally from continuous and tremendous childhood trauma, particularly from physical and sexual abuse. Children experiencing this trauma dissociate their distressing experiences and repress the memories of those experiences. This section of the article relates to the movie because his mom was â€Å"promiscuous†, so Malcolm most likely wanted to repress the memories from that time of his life. Another approach to understanding why people have this disorder would be media influences. There was an increased in the number of reported causes of dissociative identity disorder shown when the growth of popular books and movies about patients with multiple personalities. The movie itself did not have any media influences that made Malcolm Rivers have multiple personalities. However, the movie can give off a negative reaction to the public watching it because there might be more cases of dissociative identity disorder. In conclusion, Malcolm Rivers should be diagnosed with dissociative identity disorder from all the symptoms he has shown in the movie. The movie â€Å"Identity† is a great movie to watch, if someone wanted to learn more about the disorder or see an example of how a person diagnosed with dissociative identity acts. The journal article was also a good source because it backed-up one of the main causes of the disorder in the movie. Over all, the movie sends a good message to the public viewing it because the viewer can learn a lot about what causes the disorder, the symptoms of it, and they can be entertained at the same time.

The Progressive Era Essay Example for Free

The Progressive Era Essay The Progressive Era began in the mid 1890’s and continued through World War I.   It was a time when individuals were beginning to have concerns with the state of society and how government was going to handle the problems.   It also brought about a belief in human compassion and how new innovations along with scientific investigation could somehow show what the problem was with ways of solving the problems.   Two prominent figures during this era were Theodore Roosevelt and Woodrow Wilson who were both national spokesmen for the movement.    The sediment it spread changed society to what we know today, â€Å"it affected large numbers of people and expressed at many levels the excitement of progress and change† (633).   Muckraking was a term used for a journalism style of that time.   Theodore Roosevelt coined this term in 1906 to â€Å"describe the practice of exposing the corruption of public and prominent figures† (632).   This journalistic voice spread progressivism and the ideals associated with this movement very fast and to a large audience.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Progressivism was enmeshed in all parts of society.   In the political arena it called for reformation of problems that involved city, state and nation.   Intellectually, â€Å"it drew on the expertise of the new social sciences and reflected a shift from older absolutes of class and religion to newer schools of thought that emphasized physiological explanations for behavior, the role of the environment in human development, and the relative nature of truth† (633).   It brought about a cultural change that included expression in dance, film, painting, literature, and architecture.   It became the attitude and a movement that society as a whole embraced fully.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The appeal of this movement involved a wide variety of individuals that included the middle class, laborers and farmers.   In the business community it gained a large following with ideals of expansion and money.   The leaders were young educated men and women that had experience in â€Å"law, medicine, religion, business, teaching, and social work† (633).   With these young leaders came the ideology of an improved society using their expertise. There was not one single cause to unite the group, but their one single goal and that was to help create a better world in helping people to achieve this.   Their belief was strong â€Å"the high compliment of believing that, once they knew the truth, they would act upon it† was said by the social reformer Florence Kelley an active participant in progressivism.     Knowledge was an important key in this movement and formed a bond between people bringing them together instead of dividing them and pulling disheartened groups together in an effort to improve the well-being of everyone in society.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Where Populism came out of rural America, Progressivism gained support across the whole country.   Its starting ground came from cities with individuals that were feeling the pressures of urban living and factory life.   This social justice movement had its attention on the national need for housing laws, better child labor laws and better working conditions for women. Individual groups of reformers were also able to pressure municipal agencies â€Å"for more and better parks, playgrounds, day nurseries, schools, and community services† (636).   These reformers wanted a cure to suffrage rather than using charity as a bandage.   Instead of individual needs they wanted to focus more on scientific analysis of neighborhoods, occupations, and classes of people for a change to better society as a whole.   This group was most successful in passing state laws limiting the work hours for women and their right to vote. Another doctrine to come from this era was pragmatism.   A psychologist, William James had a view on the role of environment and its effect on human development along with the role humans had on the environment.   This doctrine became the main mindset for Americans from 1890’s to World War I.   He believed there were no abstractions to truth, â€Å"True ideas are those we can assimilate, validate, corroborate and verify.   False ideas are those we cannot† (639).   Everything was pretty much black and white at that time.   John Dewey applied this doctrine to education reform and the theme to emerge was that â€Å"thought evolves in relation to the environment and that education is directly related to experience† (639).   This revolution in education addressed the needs and capabilities of the children.   Not only was this theory applicable in education it could be applied to law.   Because law reflected the environment that it shaped, this was throwing away the old concept that law was universal and unchanging.   It was understood that variables in the environment affects the actions of humans. Reformation of city’s and states was another accomplishment of this era.   Municipal governments were desired that would tighten its grip on corporate activities, helped to widen utility regulations and to restrict city franchises.   Efficiency and results were the theme and it was a generation of the belief in civil service.   Though this thought was micro a macro theme was needed and it was understood that government beyond the city limits would need to become universal for society as a whole to get along .   State government during the 1890’s to 1920 worked to stiffen laws that regulated â€Å"the labor of women and children, create and strengthen commissions to regulate railroads and utilities, impose corporate and inheritance taxes, improve mental and penal institutions and allocate more funds for state universities, the training ground for the experts and educated citizenry needed for the new society† (642). During these years the industrial system had great changes employing thousands of workers and equipped with assembly lines to produce large numbers of any product that they were producing.   Results and efficiency was required to expand the company and managerial skill of the business world be used to achieve this goal.   The innovation of the model T and using the assembly line system was the seed for success of businesses today.     Ã‚  This was a time when big business was swallowing up the small business.   With this huge growth of business came the debate over trusts which influenced politics throughout the Progressive era.   Mass production enabled industry to create bigger, better and more products.   Yet this also is the time when jobs were very dangerous and unchecked.   It wasn’t until a fire at the Triangle Shirtwaist Company that killed over 500 men and women immigrants that attentions on unsafe working conditions were recognized.   Union membership was founded and striking became a way to change how the companies handled their employee who worked for them.   This created more leisure time for employees giving room for play and enjoyment of the arts. Past time games of football created the fans and movie theaters opened to audiences during this era.   When thinking of the reforms of this era you can’t forget the changes to how Americans spend their leisure time or for that matter just having leisure time.  Ã‚   Dancing, music, and even literature the director of the New York Metropolitan Museum said in 1908, â€Å"There is a state of unrest all over the world in art as in all other things, it is the same in literature, as in music, in painting, and in sculpture† (654).   This and all that is what came out of the Progressive Era.

Ethyl Acetate Properties

Ethyl Acetate Properties Ethyl acetate is the most popular ester from ethanol and acetic acid. It is manufactured on a large scale for use as a solvent. Ethyl acetate is a moderately polar solvent that has the advantages of being volatile, relatively non-toxic, and non-hygroscopic. Ethyl Acetate is an organic compound which also known as, ethyl ethanoate, commonly abbreviated EtOAc or EA. Below is the table of Ethyl Acetate general data and physical properties: FORMULA CH3COOCH2CH3 MOLECULAR WEIGHT 88.10 MELTING POINT -83.6 °C BOILING POINT 77.15 °C INDEX OF REFRACTION nd20 1.372 DENSITY d20 0.902 g/mL SPECIFIC HEAT (20 °C) 0.459 kcal/kg. °C LATENT HEAT (bp) 88 kcal/kg VISCOSITY (20 °C) 0.455 cP EA SOLUBILITY IN WATER (20 °C) 7.7 wt.% WATER SOLUBILITY IN EA (20 °C) 3.3 wt.% Table 1.1 : Physical Properties of Ethyl Acetate Ethyl acetate can dissolve up to 3% water and has a solubility of 8% in water at room temperature. At elevated temperature its solubility in water is higher. It is unstable in the presence of strong aqueous bases and acids. Ethyl Acetate can be manufactured by several types of process such as esterification, Tishchenkos reaction and Advanced Acetates by Direct Addition (AVADA) technology. In 1985 it was approximately 400000 tones in tons were produced yearly in Japan, North America, and Europe combined. The commercial Ethyl Acetate is a clear, colorless, sweet smell odor and has a minimum purity of 99.8%, with water and ethanol not exceeding 0.03%. Historical Review of Ethylbenzene Processes Ethyl Acetate is primarily produced by direct esterification of ethyl alcohol (e.g ethanol) with acetic acid, a process which involves mixing acetic acid with excess of ethyl alcohol and adding a small amount of sulphuric acid. This mixture contains about 65% of ester (EA). Then the EA is separated and purified by distillation in order to achieve commercial specification. This process considers as exothermic and safe where the heat of reaction is -0.0114kJ/mol with no danger of decomposition. Other methods that often use in manufacturing ethyl acetate are based on Tishchenkos reaction. This reaction is by combining two equivalents of acetaldehyde in the presence of an alkoxide base as catalyst. This way is a commercial method of producing ethyl acetate. Due to the observation and experiment by Tishchenko, the result shown that the obtainable yield of ethyl acetate by adding aluminum ethoxide to acetaldehyde at -20oC is 61%. In addition, new and interesting process of manufacturing ethyl acetate is Advanced Acetates by Direct Addition (AVADA) technology. This reaction used the reaction of ethylene, acetic acid and water with the presence of heteropoly acid (HPA) catalyst. It then will undergo reaction at vapor phase before being fed into the separation section where the major product and by-product being separated. This process can produce ethyl acetate at 99% concentration. The Uses of Ethyl Acetate Ethyl acetate is used as solvent in a wide range application especially in industries. It is one of the most popular solvent that used in surface coating and thinners manufacture such as nitrocellulose lacquers, varnishes and thinners. It exhibits high dilution ratios with both aromatic and aliphatic diluents and is the least toxic of industrial organic solvents. Pharmaceuticals also required ethyl acetate as an extraction solvent for the concentration and purification of antibiotics. Manufacturing of various drugs also used ethyl acetate as an intermediate. High purity product can be used as a viscosity reducer for resins used in photoresist formulations in the electronics industry. Besides that, ethyl acetate acts as a solvent in the preparation of synthetic fruit essences, flavors and perfumes. On the other hand, the extensive amounts of ethyl acetate are used in the manufacture of flexible packaging and in the manufacture of polyester films and BOPP films. It is also used in the treatment of aluminium foils. Ethyl acetate is used as solvent to dissolve the resin, control the viscosity and modify the drying rate in inks for flexographic and rotogravure printing. Based on ICIS article that has been updated April 2008, the global demand is predicted to grow at 3-4%/year because of strong demand for surface coatings and as a replacement for restricted solvents. China and Southeast Asia are largest demand while Western Europe is developed markets. Southeast Asia and China are expected to become the most popular for ethyl acetate production and consumption. The Southeast Asian paints and coatings market is expected to grow at 5-6%/year. Japans Daicel Industries is converting an acetic acid plant in Otake, Hiroshima to produce ethyl acetate by using bio-ethanol as the raw material. It will have a capacity of 50,000 tonnes/year with production expected to start in spring 2009. The global demand growth for US is about 2%/year to 2009. According to ICIS Chemical Business (ICB), US demand increased from 88,500 tonnes in 2005 to 95,300 tonnes in 2009. Around 60% of ethyl acetate is consumed in US as a solvent in a variety of coating formulations. These coatings are used for wood furniture and fixtures, agricultural, construction and mining equipment, containers and closures, auto refinishing, and maintenance and marine applications. Around 20% of the ethyl acetate is used as solvent-based architectural coatings for both exterior and interior use. This sector has been growing at approximately 6%/year. However, in industrial coatings the usage of ethyl acetate is decline because of environmental constraints has largely been completed and future growth in the US is estimated to be a healthier 2.5%/year up to 2009. OEM (original equipment manufacturer) solvent-based coatings have been declining slowly in the US. The OEM sector, however, is the largest and represents 58% of ethyl acetates coatings use demand. The remaining sector, specialty coatings, which includes marine coatings, has held steady. The European market is reported to be balanced with big supply and steady demand. However, future demand is expected to be flat and or even contract slightly as consumption by local paints and inks sectors shrinks as production moves eastwards. In the UK, INEOS has acquired BPs ethyl acetate business including a 250,000 tonnes/year plant in Hull. Future consolidation is seen as possible in Europe as ethylene-based producers struggle to compete against more competitive ethanol-based production. Europe could also become more reliant on imports. PROCESS BACKGROUND Esterification Esterification is a chemical reaction process between alcohol and carboxylic acid in the presence of catalyst that formed ester. This mixture converts to ester about 65% at room temperature. The commonly concentrated sulphuric acid is acting as a esterification catalyst to enhance the reaction. The sulphuric acid removes water to help shift the equilibrium towards forming more ester product. Water is a by- product and must be removed in order to get the equilibrium in the desired direction. This process is a simple process, well known reaction, and moderately exothermic where the heat or reaction, H is -0.0114kJ/mol with no danger of decomposition reaction. The optimum temperature for this reaction is in the range of 363 K 400 K while the optimum pressure is in the range of 20 bar 40 bar. Ethanoic Acid + Ethanol Ethyl Acetate + Water CH3COOH + C2H5OH CH3C02C2H5 The reaction between acetic acid and ethanol to produce ethyl acetate in the presence of concentrated sulphuric acid. This process is released a few amount of heat to the surrounding and classified as exothermic reaction. This reaction is called a homogeneous liquid phase. Water is formed in the reaction is removed continuously to ensure maximum conversion of acetic acid. The catalyst can be heteregenous and homogeneous. There are two categories of catalyst that can be used in this reaction, mineral acid catalyst and para toluene sulphonic acid or ion exchange resins can serve as heterogenous catalyst. Process Description Ethanol and acetic acid together with crude ethyl acetate is fed into the reactor in the presence of concentrated sulphuric acid to produce ester and water. Then, the products are fed into the distillation column (DC1) to separate water and ester (ethyl acetate). The bottom product of DC1 is water and the overhead product is ethyl acetate. This part are taken by dehydration and azeotropic distillation of ethyl acetate and water. The overhead product is passed to the decanter to separate the organic phase and aquase phase. The upper layer known as organic phase while lower layer known as aqueous phase. partially of organic phase is fed into the reactor and another potion of organic phased is passed into the second distillation column (DC2). The second column is a purify process where to give the pure ethyl acetate (bottom product). The top product is a mixture that consists of ethyl acetate, water and ethanol. this mixture is separated after cooling process and the light phase is fed back to DC2 and the rest is transferred to the second decanter where its process is same as the first decanter to separate the organic and aqueous phase. Pipeline is used to combine the aqueous phase from the both decanters and distilled in the third column to give waste water at the bottom product and again ester, water and alcohol. This stream is recycled into the reaction column. Raw Material Ethanol: Ethanol is one of the material that is being used in the esterification process. it is also known as ethyl alcohol. ethanol is a volatile, flammable and colorless liquid. Ethanol can be obtain by fermentation of plants. Ethanol is relatively non-toxic and dissolve in water. It is a renewable energy source and it has less harmfull effects on the environment. However, ethanol will also give an impacts to the environment. The use of ethanol is a problem for conventional air pollutants. Ethanol used will increase the emission of chemicals that lead to the production of ozone. Ethanoic acid: One of the raw material needed to complete the reaction. Ethanoic Acid is one of the simplest carboxylic acid. it is a colourless liquid with an unpleasant pungent odour. ethanoic acid is produced by the oxidation of ethanol. Ethanoic acid is highly corrosive to the metals and it is also potentially harmful to our health. Sulphuric acid (catalyst): Sulphuric acid is chosed as homogeneous catalyst in this reaction. this catalyst is very effective mineral acid catalyst. however, this sulphuric acid is strongly corrosive and leaves sulfate residues. besides that, it is also generates large amount of heat. Tishchenkos Reaction Tishchenkos reaction is a reaction that need the presence of an alkoxide base while two equivalents of acetaldehyde is combining. This way is becoming commercial method of producing ethyl acetate in Europe since acetaldehyde become important intermediate on the basis of acetylene. Due to Tishchenko, the obtainable yield of ethyl acetate by adding aluminum ethoxide to acetaldehyde at -20 °C is 61%. The reaction is expressed by, [catalyst; alkoxide base (e.g Aluminum Ethoxide)] 2CH3CHO CH3COOCH2CH3 (Acetaldehyde) (Ethyl Acetate) Figure 1.3: Tishchenkos process Process Description For the process of Tishchenkos reaction, acetaldehydes will be introduced to the catalyst solution continuously. The catalyst is first need to be prepared by dissolving granular Aluminium in an ethanol-ethyl acetate mixture in the presence of aluminium chloride and small amount of zinc chloride. This catalyst (basicly Aluminum Ethoxide) is prepare uncontinuosly. In reactor, while acetaldehyde contact with the prepared catalyst, the ratio of the reaction partner must be adjust in order to obtain 98% transformation of acetaldehyde in one passage. A further 1.5% transformation is achieved in stirring vessels. Consecutively to make sure the reaction temperature is kept to 0 °C, brine with normally -20 °C will be used as the cooler. This reaction takes approximately 1 hour to completely mix before being transfer to residue separation. Next, separator is needed to remove the residue that contain in the mixture. The distillable products are removed by evaporation. For the economic issue, the residue is treated with water to regain ethanol. For the residual slurry, it can either be given to biological degradation plant or it can be burned together with other organic waste products. Subsequently, the distillable products need to be purifying in so that it can achieve commercial purity which is approximately 99.8%. Therefore, distillation column is used. For the 1st series of distillation column, light end are separated and this steam is further distilled to take non-converted acetaldehyde, which is returned to reactor. Then ethanol that contain ethyl acetate is separated for reuse in catalyst preparation. The bottom of 1st column give the high quality or grade of ethyl acetate that only will obtain at the head of the next column due to the need of separation of high boiling condensation products in mixture with ethyl acetate which will be remove at the bottom. In addition, further small column is needed to recover another part of pure ethyl acetate to isolate acetaldehyde diethyl acetal. Hence, after purification is done the recover product can used as an important intermediate or hydrolyzed in an acid medium to give reusable acetaldehyde and ethanol. Raw Material Acetaldehyde It is also known as ethanal. Acetaldehyde is one of the most important aldehyde and is being produced in a large scale industrially. This substance can be produced by the oxidation of ethylene. Although it is not a costly substance and it is very easy to get, acetaldehyde is a very toxic substance. It can give harm to living organisms and toxic substance is not an environmental friendly. It is an air pollutant resulting from combustion. Advanced Acetates By Direct Addition (Avada) In AVADA process, ethyl acetate is produced by reacting ethylene with acetic acid and water in the presence of heteropoly acid catalyst. The amount of water being used is in range from 1-10 mole% based on the total ethylene and acetic acid. The presence of water can reduce the amount of unwanted by-product that formed by the reaction. The mole ratio of ethylene to acetic acid in the feed stream is in range of 6.0 to 12.2, while for ethylene to water, the mole ratio is between 8.0 to 17.0 and the mole ratio of acetic acid to water is from 1.25 to 1.40. Heteropoly acid CH2 = CH2 + CH3C02H CH3C02CH2CH3 (ethylene) (acetic acid) Water (ethyl acetate) The reaction is preferably carried out at a temperature in the range from 160 °C to 195 °C while the preferably pressure is between 1200 kPa to 1500 kPa. The catalyst used must consist at least one heteropoly acid salt of a metal such as litium, cuprum, and magnesium which supported on a carrier. The heteropoly acid used is phosphotungstic acid while the carrier is silica. Heteropoly acids usually have a high molecular weight in the range of 700 8500 and include dimeric complexes. They have high solubility in polar solvents such as water or other oxygenated solvents. In order to achieve optimum performance, the carrier should free from metals or elements which can affect the catalytic activity of the system. To prepare the carrier, firstly the heteropoly acid is dissolved in distilled water, demineralised water, alcohols or other non-aqueous solution. Then the carrier is soaked in the acid solution for several hours with periodic manual stirring. After that it is filtered using Buchner funnel to remove any excess acid. The wet catalyst is then placed in an oven at elevated temperature for several hours to dry. Lastly it is allowed to cool to ambient temperature in desiccators. Now this supported catalyst is ready to be used in esterification process. BASIC FLOW DIAGRAM OF ETHYL ACETATE PRODUCTION BY AVADA The basic flow diagram of the unit is shown in the above figure. The unit consist of feed section, reaction section, and product and by-product separation section. The basic flow diagram of the unit is shown in the above figure. The unit consist of feed section, reaction section, and product and by-product separation section. The fresh feed which contain ethylene, acetic acid and water are fed into the vaporiser. Vaporiser is used to change the liquid phase feed into vapour phase as the reaction is preferably carried out in the vapour phase. It also includes a recycle system for both unreacted feeds and all the major by-products. The combined feed vapour stream is fed to a reactor train comprising of four fixed bed reactors in which each reactor already filled with catalyst. The reactants are passed over the catalyst suitably at a GHSV (Gas Hourly Space Velocity) of 300 to 2000 per hour. The first three reactors are fitted with acid/water injection to the exit streams. This is to facilitate independent control of reactor inlet temperatures and to maintain the desired ethylene to acid ratio. The fourth reactor functions as finishing reactor where the final conversion of ethylene and acetic acid to ethyl acetate is achieved. There are four by-product formed from the reaction which are 2-butanone, acetaldehyde, ethanol and diethyl ether. The crude product stream exiting the last reactor is cooled before entering the flash drum where the separation of non-condensable (gas) and condensable (liquid) phases occurs. The recovered gas is recycled back to the vaporiser while the liquid stream enters the product separation and purification system. In this system, series of distillation columns designed to recover and purify the final product. It is also to recover the unreacted acetic acid, water, ethanol and light ends streams for recycling back to the vaporiser. Advantages and Disadvantages of AVADA The AVADA process is superior to other additional processes in terms of environmental protection. This is because AVADA uses a solid acid catalyst. Therefore, there are fewer requirements for the treatment and disposal of aqueous effluent compared to traditional esterification reaction that produces as much water as ethyl acetate. Since AVADA process eliminates the intermediate esterification steps and the need for ethanol, it save about 20% on energy cost compare to conventional routes. The AVADA process produces high purity (more than 99%) which reduces the production of by-products. Undesirable by products such as 2-butanone and acetaldehyde may be controlled by careful adjustment of feed composition and reaction temperatures while maintaining acceptable ethyl acetate yields. The production of c4 unsaturated hydrocarbons is significantly reduced. Therefore, the catalyst lifetime can be extended. The disadvantages of AVADA process is rapid catalyst deactivation thus disturbing the quality of the product. However, this problem can be solved using a bed porous silica beads with the heteropolyacid impregnated in the pores. PROCESS SELECTION There are three methods found in the production of ethyl acetate which are Tishchenko, Esterification and Advanced Acetates by Direct Addition (AVADA). By considering all of the advantages and disadvantages of each process, the Acetates by Direct Addition (AVADA) was chosen as the best alternative to produce ethyl acetate. The main reason AVADA was chosen are because the catalyst used is environmental friendly. TICHSHENKOS ESTERIFICATION ADVANCED ACETATE BY DIRECT ADDICTION (AVADA) RAW MATERIAL Acetaldehyde Ethanol Acetic acid Ethylene Acetic acid Water CATALYST Alkoxide base (e.g aluminium ethoxide) Produced large amount of aluminium residue which is not easily separated Produce large amount of wastewater Acid catalyst (e.g Sulphuric acid) Very corrosive Produce sulphate residue Heteropolyacid (e.g phosphotungstic acid) The catalyst lifetime can be extended Using solid catalyst- waste free and less requirement for treatment OPERATING CONDITION 0 °C 1 hour reaction 90 0C 127 °C 20 bar 40 bar 160 °C 195 °C 1200 kPa 1500kPa PURITY Crude ethyl 61 % purity Crude ethyl 55 % purity Crude ethyl 99 % purity NUMBER OF EQUIPMENT USE 5 equipments ( distillation column, feed surge drum, reactor, separator, mixer) 3 equipments (reactor , decanter, distillation column) 5 equipments (vaporizer, reactor, flash drum, distillation column, compressor) REACTION 2Acetaldehyde Ethyl Acetate ethanol + ethanoic acid ethyl acetate Ethylene + acetic acid Ethyl acetate AVAILABILITY OF RAW MATERIAL Produce in large scale in Europe due to the importance of acetaldehyde as intermediate on the basis ofacetylene Easy to get in china Table 1.2: Comparison between all processes PROCESS ADVANTAGES DISADVANTAGES AVADA (Advanced Acetates By Direct Addition) Undesirable by products such as 2-butanone and acetaldehyde may be controlled by careful adjustment of feed composition and reaction temperatures while maintaining acceptable ethyl acetate yields. The production of c4unsaturated hydrocarbons is significantly reduced. The catalyst lifetime may be significantly extended. The process economics are improved by a reduced requirement to operate process purge streams to reduce the recycle of undesirable by-products and by the ability to de-bottleneck the product purification system. Very high purity (>99%). Avoid environmental hazards by using heteropolyacids (environmentally friendly). More energy efficiency save ~20% on energy costs. Using solid catalyst waste free and less requirement for treatment and disposal of aqueous effluent. Rapid catalyst deactivation thus disturbing the quality of the product. Esterification Well known reaction. Moderately exothermic reactions with no danger of decomposition of reactions. The reaction also exhibit second order ractions when no strong acid is present and a kind of autocatalytic behaviour when the acid is introducespurification system. Acidic feedstocks Concentrated sulphuric acid is a harmful chemical reagent. Generates large amount of heat. Tishchenkos Reaction The raw materials are produced in large quantities. The price of the raw material is not very costly. It is an alternative way due to expensive price of ethanol. Produce large amount of aluminium residue which is not easily separated due to the use of aluminium ethoxide as a catalyst . The use of the catalyst can create a large amount of wastewaters and thus extra cost is needed to treat the waste. The raw material, acetaldehyde is a very toxic substance.

Marijuana: Safe, Therapeutic, and Illegal :: Pro Marijuana Legalization

Marijuana is illegal. Illegal to possess, purchase, distribute or grow. To start off the basic non-creative, non-read between the lines question; Why? Why was marijuana made illegal that fateful day 68 years ago. Is there a justifiable reason to the original criminalization and continuation of that law to present day? So, again I ask; Why? Yet, besides the reason why marijuana is illegal many are against the prohibition laws. However, possibly just as many are for keeping marijuana in the same position it has stood for 68 years.

Marijuana: Safe, Therapeutic, and Illegal :: Pro Marijuana Legalization Marijuana is illegal. Illegal to possess, purchase, distribute or grow. To start off the basic non-creative, non-read between the lines question; Why? Why was marijuana made illegal that fateful day 68 years ago. Is there a justifiable reason to the original criminalization and continuation of that law to present day? So, again I ask; Why? Yet, besides the reason why marijuana is illegal many are against the prohibition laws. However, possibly just as many are for keeping marijuana in the same position it has stood for 68 years. Prohibitionists’ only non defensive argument is that marijuana is a gateway drug.

Philosophy :: essays research papers

Interpreting Plato Alfred North Whitehead once remarked that all of philosophy is but a footnote to Plato. This proves true in the case of St. Augustine’s Confessions, where he specifies Plato’s good as God by personalizing the forms, Eros, sin, and recollection. Specifically, Augustine’s idea of â€Å"original sin,† forgetfulness and recollection follow the philosophy of Plato, bringing them into the â€Å"God realm,† rather leaving them in a figurative sense open for interpretation. In the Confessions, Augustine says that â€Å"the soul commits fornication when it is turned away from you and, apart from you, seeks such pure, clean things as it does not find except when it returns to you† (2.6.14). Here Augustine provides an overview of his idea of God: it is initially with God, because it must turn away, or forget, in order to leave God, but is left unsatisfied until it returns, or remembers. This is a direct use of Plato’s theory that the soul of man originally dwells with the forms in the realm of the â€Å"good,† then the soul forgets on earth what the â€Å"good† is, but spends life trying to remember. For both Plato and Augustine, the journey begins at birth. When a person is born, they possess both an original sin and an original innocence. Being born into the world, people are certainly corrupted by society and prone to sin, because in the eyes of Plato and Augustine, the body itself is corrupt and leads to sin. At the same time, though, man is born with â€Å"good† inside of them. The soul of humankind comes from God or from the â€Å"good,† and it has a recollection of the good of which it once knew. Augustine said of infancy that, â€Å"the sin that is in him you have not made†¦For in your sight, no man is clean of sin, not even the infant who has lived but a day upon earth† (1.7.11). So what is it about living a day on the earth that makes an infant sin, and what is it in a person that makes them turn away from sin? According to Plato, the body leads to sin. As with Plato, while a person becomes a sinner when they enter into the body, they have with in them an inherent, incorruptible good, the soul; only it forgets from what it came, thus turning away from the good. In the speech of Diotima, she says that love is giving birth to new ideas, bringing beauty in the presence of mortality.

Why Does He Do Me This Why?

Osikenoya Usman-Aliu Professor Katherine A. James EN101 February 21,2013 Narrative Essay Why Does He Do Me This Way? I can remember the first day I laid eyes on him it was truly love at first sight. My name is Lily Jackson and I’ll tell you why love is blind. I was 14 years old and in the eighth grade year. I hated eighth grade year because everyone had a boyfriend except for me. I was always the outcast. That all changed for me the second semester in eighth grade. My teacher Ms. Williams announced to the class that we were having a new student join room 411.Everyone was excited, but I wasn’t because it was going to be another student that didn’t like me. Ms. Williams went outside and said â€Å"Class meet Jerome† Everyone started whispering: â€Å"where is he going to sit†? â€Å"What if I don’t like him†? The boys stated† I might have to beat him up if he talks crazy to anybody†? I slouched back in my seat covering my fac e. When he finally walked in everyone’s mouth dropped. The girl’s eyes grew big and the boys were angry. He entered the class and said â€Å"hey everyone† in this nice deep voice.Jerome was tall, handsome, had a clean fade, and beautiful straight white teeth. â€Å"He’ll sit next to Lilly† said Ms. Williams. I shouted BUT I ALWAYS SIT BY MYSELF. â€Å"This will give you time to open up Lilly† Ms. Williams stated in her eager voice. When Jerome sat next to me he smelt so good. I was nervous, but actually I was happy to sit next to the new boy. It was around the time of graduation and Jerome and I had become very close. We were attending the same high school. We grew a bound that nobody could touch. We had become best friends.A few weeks after graduation high school had begun and Jerome and I had almost every class together. Around senior year we grew even closer he would come pick me up for school and drop me off at home. All the girls wanted Jerome because he had a nice body, he was nice, and he gave everyone the benefit of the doubt. The most popular girl in the school was Jenna Hawkins. Every boy dreamed of being with her because she had long beautiful hair, no pimples, and was extremely smart. Her parents were millionaires so she was very spoiled. She drove a Bentley to school, which was all white and was a drop top.One day Jenna approached Jerome and asked him would he like to go to homecoming with him of course he said yes because he never let people down. I was very angry because Jerome and I always attended homecoming together; it was our tradition. When Jerome had dropped me off he asked me who I was attending homecoming with. â€Å"I’m not going â€Å"I stated in my mad voice. â€Å"Are you mad? † Jerome asked. â€Å"I responded NO! † â€Å"Do you want to go with me? † he asked. â€Å"No have fun with Jenna she’s real nice† I responded. He finally drove me off. I ran in my room and started crying.The next day at school I found out that Jerome and Jenna started dating. I was extremely upset. There was a rumor going around that I liked Jerome. Jerome approached me and said â€Å"Do you like me? † I stated â€Å"NO† He stated, â€Å"If you do I understand† I finally stated, â€Å"Yes I like you, I love you Jerome† â€Å"But we’re just friends Lilly and you know that† Jerome stated. I ran off filled with embarrassment. I stopped getting rides from Jerome and I completely cut him off. When Graduation came around I was isolated once again. I didn’t talk to no one. Jerome said, â€Å"I love you Lilly, but only as a friend†.

“9” by E.E. Cummings Analysis Essay

Edward Estlin Cummings was a unique poet with an equally unique writing style. E. E. Cummings was born on October 14th, 1894 in Cambridge, Massachusetts. In 1916, Cummings graduated with a master’s degree from Harvard University. During his studies, he was subject to many great writers such as Gertrude Stein and Ezra Pound. After working for five months as a volunteer ambulance driver in World War I, he was captured by French authorities. He was accused on accounts of espionage. After the war, he settled into a life in which he bounced around from houses in rural Connecticut and Greenwich Village. He also traveled through Europe meeting various poets and artists, including Pablo Picasso. During his life, Cummings won a number of awards for his unique style of writing. At the time of his death in 1962, he was the second most widely read poet in the United States, only behind Robert Frost. In this essay, we will discuss three distinct features of his writing that made it so unique. These features included literary devices, imagery, and symbolism. One of the most prominent poetic devices in E. E. Cummings poem, â€Å"9†, is alliteration. This literary device is obvious throughout the poem. For example, in the first stanza, â€Å"There are so many tic-toc clocks everywhere telling people what tic-toc time it is, for tic-toc instance, five toc minutes toc past six tic† (Cummings Web). Cummings uses the phrase tic-toc, and other variations of that to create a sense of repetition. This fits nicely into what the major theme of the poem is. Cummings believes that watching and keeping track of time gets repetitive. Through alliteration, Cummings creates a sense of repetition while summarizing the overwhelming theme of the poem. Another major poetic device Cummings uses in his poem â€Å"9† is imagery. Cummings makes use of descriptive phrases that practically paint a picture in the reader’s mind. For example, â€Å"Spring is not regulated and does not get out of order, nor do its hands a little jerking move over numbers slowly† (Cummings Web). The section â€Å"Its hand a little jerking move over numbers slowly,† instantly gives the reader the image of a clock. In the way he conveys this, it’s clear that he feels time is moving very slowly. In the third stanza, â€Å"We do not wind it up, it has no weights, spring wheels inside of its slender self, no indeed dear nothing of the kind† (Cummings Web), Cummings creates vivid imagery. This shows that Cummings is relating how he has no use for a clock and doesn’t care for the principle of keeping time. He would rather live life time free, without having to worry about being on time or being late. The third and final poetic device that shows up in the poem, â€Å"9†, is symbolism. To begin the poem Cummings uses symbolism. The number â€Å"9† refers to the number of times he uses the words, â€Å"tic-toc†, â€Å"toc-tic†, â€Å"tic-tic†, â€Å"toc†, and â€Å"tic†. Also, as seen in the fourth stanza, â€Å"So when kiss spring comes, we’ll kiss each kiss other on kiss the kiss lips because the tic clocks toc don’t make a toc-tic difference to kiss kiss you and to kiss me† (Cummings Web). Cummings uses the word â€Å"kiss† to complicate and clutter the verse. If you remove those words, he simply summarizes all of his thoughts in the last stanza. He says when spring comes; we can kiss because the clocks don’t make a difference to you and me. This symbolizes that Cummings can’t wait for the spring and summer months when the clocks don’t play a role in his life. In conclusion, Cummings uses his poem â€Å"9† to relay his feeling to time. He feels that clocks are constantly telling people what time it is, that they are too late or too early. He believes they should be allowed freedom, which the clocks don’t seem to give. In the summer, however, the clocks don’t matter because it’s a time for relaxation and fun. He could really care less about the clocks.

Mo-tzu’s Argument Against Music Essay

Mo-tzu (also called Mozi, Moz, or Micius in Latin) was a renowned philosopher in China back in about 390-470 B. C. during the time of the Hundred Schools Thought (Wikipedia, 2007). Having founded Mohism, he argued about the inadequacy of Confucianism and Daoism on the need for a mortal being to self-reflect and meditate upon oneself. He also insisted that, instead of rituals and singings, what human beings need are acts of authenticity that does not include the use of drums, zithers, and pipes. He, therefore, stressed out: â€Å"To have music is wrong† (Par. 1, Book VIII, Chapter XXXII). Main Body We all agreed that Mo-tzu presented a very well thought of argument against music. This can be seen when he stated, Although the body knows they are comfortable, the mouth knows they are gratifying, the eyes know they are delightful, and the ears know they are pleasing, yet they are found not to be in accordance with the deeds of the sage-kings of antiquity and not to contribute to the benefits of the people at present. (Par. 1, Book VIII, Chapter XXXII) In saying this, he implied that music did not have anything to do with the greatness and success of the sage-kings†¦ that it did not fulfill the basic needs, unlike the boats and the carts that were built from the same contribution of the ancient citizens. It slowed production by wasting labor on things that are of no use. He stated, The levy of heavy taxes on the people to construct the big bell, the sounding drum, the ch’in and the she, and the yY and the sheng, is not at all helpful in the endeavor to procure the benefits of the world and destroy its calamities. Therefore Mo-tzu said: To have music is wrong. (Par. 3, Book VIII, Chapter XXXII) Mo-tzu is absolutely correct. Yet in spite of this, if people accept that music is not useful in acquiring the needs of this world, such as food, clothing, and rest (Par. 3, Book VIII, Chapter XXXII), then they must also understand that, just like music, philosophy is just as useless in acquiring the needs of this world, such as food, clothing, and rest (Par. 3, Book VIII, Chapter XXXII). In fact, as compared to music, philosophy presents greater cause for men to think deeply, and run into sickness and chaos (with oneself or with the society) that, in turn, makes them more prone to hunger, to state of undress, and to unrest. What philosophy has failed to give men, music could give with just a stroke or a beat of the instruments. True, musical instruments cannot be directly eaten and cannot cloth the naked, yet the instruments were also considered treasures in the long ago, which means that the owners could sell it for a chance to buy food or clothing in exchange of the musical instruments. When it comes to giving rest, however, music has the capability to give rest to those who are bothered psychologically or biologically. Philosophy, on the other hand, cannot be exchanged for food, clothing, or rest, since it all runs in the mind of the wise men. Thinking about the statements of the wise will just make men hungrier, poorer with less clothing, and more troubled. I, therefore, stress out—to have philosophy is totally wrong! Conclusion Mo-tzu failed to acknowledge that music is an art that sprouts from the very being of the individual. It is like painting, sculpture, literature, or the use of colors. It is an expression of what human beings feel, think of, believe in, or acknowledge. It comes from the mind. With this, it is very obvious that to say that music is totally wrong would also mean that philosophy is totally wrong, since the latter is also an expression of what human beings feel, think of, believe in, or acknowledge. Music comes from the mind just as philosophy comes from the mind. The only difference is that philosophy centers on chosen beings—those who are more gifted and wise—than when compared to music, which is so ordinary and can be expressed by anyone who dreams of expressing himself. Yet they both come from the mind. Even if both have their own sides of gains, both are totally incapable of destroying calamities.

In what ways television affects Essay

AIM: I propose to find out what children say about how television affects their play. Socialisation is a very important concept in sociology and the role of the mass media is highly debateable. Many sociologists believe that media effects start by setting out an overall relationship between media and its audience. They are often called models of media effects. I will interview the children these interviews will be unstructured. The children will be interviewed separately. Gender will be a comparison I look at to and whether the gender affects whom the children imitate. CONTEXTS AND CONCEPTS: The study of Bandura Ross and Ross uses the term of social learning theory to assert that children copy behaviour another example of this is copycat violence found in Hagell & Newburn’s study. In my research will ask the children whether they say they act violently due to the violent content they may have viewed and whether they have chosen to imitate these programs. Hagell & Newburn’s study compared young offenders viewing behaviour with non-offending teenagers. They found the differences were few between the two groups and what they watched, with hardly any having seen the films that were causing the concern at that time. A few members of either group had an interest in a violent output. The young offenders had less access to different media types. Other factors instead of media could have been causing the differences in their behaviour. The other context being analysed is Bandura Ross Ross who looked at whether children learnt behaviour through observation. This is the idea of the social learning theory. Children were made to watch a violent model be aggressive towards a five-foot ‘bobo’ doll. Later the children were given an aggressive arousal and then taken to another room where they were monitored as to how they reacted towards the ‘bobo’ doll, after seeing a model do this. The different concepts are is copycat violence this is violence that occurs as a result of copying what is seen in the media. Catharsis another theory is the process where tension is relieved, for example violence on screen that provides a safe outlet for people’s violent inclination. The final concept is desensitisation some theorists argue that the constant media diet of violence makes them less sensitive to real human suffering. These concepts tie in with the idea children are passive sociologists believe this, children respond easily to everything. This is the reason for watershed on T. V at 9pm because what comes on television isn’t suitable enough for children and there is a fear that the children will imitate this behaviour. (337) MAIN RESEARCH METHOD AND REASONS: The method I will be using is by interviewing the children by asking them to explain the reason for their behaviour. The questions I will ask the children will be questions not only requiring the answers that I need but there will be a series of distracting questions so the children will not know the aim of the questions being asked. Interviews are an advantage because it is better to gather all the information needed for an interview because you get to understand what the interviewee’s true opinions are. Interviews are flexible and can be used in different ways; also the ethical advantage is consent of the participants the theoretical advantage is that at applies to the law of interpretivists (Action theory). You can use empathy to understand their opinions in depth; these methods generate higher levels of validity of these results. They give a general understanding of the problem, there is less pressure on the interviewee and their answers are more spontaneous. Important concepts are uncovered about the information that will help me conclude whether the children imitate what they watch. When interviewing the children I will be asking them which programs they imitate and this will give me an insight into whether there is a pattern with what they watch. The sample I will be using for the interviews are of children from the ages of five to ten years old, because at this stage of childhood where television will be their main interest and there is a large variety if television for children of these ages also this is the age children are most likely to be influenced by the media. The genders of the children being used are varied so I will be using five boys and five girls. The children all come from the Borough of Newham of East London. It is easier for me if the children are living in the same borough there will be an easier access to these children and it will be easier for me and the children. The sample of the children I will be studying is opportunity sampling as the sample depends on whether the adults agree to their children being in the sample. The consent for whether the child will participate will be the decision of the adults. In Bandura’s study he gave the children an aggressive arousal and in this study will not do this as the aggressive arousal means that the children could have acted violently because of the arousal given and not because they were imitating the models behaviour. (425) POTNETIAL PROBLEMS The interviews of the amount of children I will be looking at can be very time consuming. With this study I need to be aware that the sample isn’t appropriate enough to apply to the whole population because all the children are from the same background and all from a similar ethical background and there may be a pattern in their behaviour. The main practical issue is whether the adults will allow their children to take part in the study. These types of questionnaires are basically a conversation dominates by the interviewer. These unstructured interviews may also go off the initial idea of what is being interviewed. Also with the amount of children I will be looking at and the sample of children I will be looking at there will be a lot of activity so it may be difficult to record all of their behaviour. These interviews are more difficult to analyse, and there are less details provided on the concept being asked. Ethical problems are mental harm to the children if they don’t like the questions being asked of them. Right to withdraw will be an ethical issue also because the children may not feel they have the right to leave and stop asking the questions. The final ethical issue is informed consent, which will be coming from the child and not the parents. The children should be able to make the decision but when a child is involved the parents have the consent. Time consumption is a practical issue through finding time to interview ten children. Being able to get the children to understand the question and also to cooperate may be difficult. Likewise another ethical issue is the children may not understand the debriefing. If they don’t understand the debriefing there will be an issue of this ethical guideline and the parents will also have to also be debriefed too.
