The Emerging Role of Nurses in the Patient Protection and Affordable Research Paper

The Emerging Role of Nurses in the Patient Protection and Affordable Care Act - Research Paper Example One of the things that stood out to me the most about the condition of this clinic was their need for medical staff. The free clinic was within two miles of three major hospital systems, and sat in the literal shadows of one of these systems in the late afternoon; yet with all of these highly skilled and highly trained medical personnel in the surrounding area, the free clinic still lacked for providers. This shocked me. Yet despite my confusion, one of the providers at the free clinic explained to me that the shortage of practitioners, particularly nurses, was felt at the large clinics surrounding our free clinic as much as at the free clinic, and as I later found out, could be found in areas as diverse as primary care nursing and oncology nursing (Bishop, 2010). I quickly realized this was an effect of the current ‘sick care’ system. ... To overcome this problem, I realized that a supply and demand solution would be required to move our current system from a sick care system to a health care system. In a 2011 interview in the New England Journal of Medicine, Secretary of Health and Human Services Kathleen Sebelius echoes this idea by saying, â€Å"I believe that refocusing health interventions at an earlier stage, placing more focus on health and wellness strategies, would help reduce demand and promote population health.† (Iglehart, 2011) In this quote, Sebelius shows the supply and demand solution necessary to convert the sick care system to a health care system. By emphasizing health and wellness strategies at earlier stages, Sebelius is hypothesizing that, while a greater investment may be required up front, these efforts will eventually keep people healthier in the long term, and will create a true health care system: one in which the goal of providers is to keep patients healthy and prevent sickness, not just treat the sickness as it occurs. She further explains this idea and how it could help the provider shortage I witnessed by saying, â€Å"Unfortunately, the shortage of [providers] has been ignored for a decade or more, along with the fact that doctors whose practices are devoted to primary care are under paid compared with specialists. So starting with the stimulus law and continuing in the ACA, there has been a significant focus on expanding the pipeline of primary care practitioners, gerontologists, and general surgeons†¦ We have also put more money into nurse training and education†¦Ã¢â‚¬  (Iglehart, 2011) Clearly, the new health care law has the vision to transform the sick care system into a

Patterns of Behaviour Essay Example for Free

Patterns of Behaviour Essay To form a reaction the particles must collide in high speed. The faster the particles collide the more kinetic energy is produced. This produces a bigger reaction. There are five key variables that affect the rate of a reaction (in this case with a solid and a solution): Change in temperature An increase in heat energy within the particles leads to more kinetic energy. Therefore there is more collision of particles and it increases the rate of the reaction. When we decrease the amount of heat energy, this will evidently slow down the reaction. For example we slow down the process of our food rotting by placing it in a fridge or a freezer. Change in concentration The concentrations of acids are classed in molars, so 2m would quite a strong concentrated acid, 0. 5m would be a very dilute weak acid and 1m would be in between the two. Also, the more concentrated the acid, the more particles it contains, so there is more of a chance for collisions.   Change of particle size Increasing the surface area of the particles would lead to more collision. We do this by making the particles smaller. For instance peeling a large potato would not take as long as peeling four small potatoes; this is because the smaller potatoes have a larger surface area for you to peel. Pressure (for gases only) Increasing the pressure would bring particles closer together so there would be more of a chance for collision.   Catalyst A catalyst lowers the activation of energy required, consequently there being a faster reaction. The three variables we are choosing to show which effect the rate of reaction in our experiments are: Particle size Concentration   Temperature Pressure was inappropriate to use as a variable, because we were not using two gases and a catalyst was unsuitable to use for small tests like these. I think that the tests in changing the temperature will have the fastest times, as the hotter a solution is the more the particles will move and collide, thus the rate of carbon dioxide being produce will be faster. I also think that the large particles test will take the slowest amount of time because of the lack of surface area and the reverse will occur with the test with powered calcium carbonate. Plan We will be running a various number of experiments to prove what effects the rate of reaction with calcium carbonate (marble chips) and hydrochloric acid. The balanced equation for these reactants along with the products: Calcium carbonate + hydrochloric acid calcium chloride + carbon dioxide + water Ca Co + 2 HCl Ca Cl + Co + H O When experimenting with the effects of the particle size we will use three sizes: large marble chips, small marble chips and powered calcium carbonate. For the tests in concentration of acid we will use 2m, 1m and 0. 5m. We will use 50cc of hydrochloric acid in each test to guarantee precise results. Finally for the experiments with the changes of temperature we will be heating the acid using a bunsen burner for two temperatures: 30i and 40i , then leaving the acid at room temperature (around 22i ). We will measure the temperature accurately using a thermometer. These will be the only three things that we are going to vary, to explain what affects the rate of reaction. We will also only be testing one variable at a time. For example, in the test for concentration we will obviously be varying the concentration of the acid (0. 5, 1 and 2m) but we will be keeping the temperature and the particle size the same (room temp. and small marble chips). To tell us what actually affects the rate of reaction we will monitoring how fast carbon dioxide is given off. To find this out we will have a plastic basin containing water. A test tube measuring 10cc filled with water will be held upside down in the basin of water and a delivery tube will be attached to the beaker holding the acid and calcium carbonate and the other end will be positioned in the test tube in the water. We will use all the same apparatus to ensure everything is fairly tested and is accurate to the equipment we are using. As the acid reacts with the calcium carbonate, carbon dioxide is released. This will travel through the delivery tube and into the test tube. The test tube will fill up with carbon dioxides and the water will pushed out. We will be timing this with a stop clock. As the water descends to 1cc we will record the time, then at 2cc, again at 3cc and so forth. At the end of each experiment we should have 10 times recorded. For each factor, instead of just performing the experiment once, we will repeat it three times to provide us with a more accurate end result. In total we will be doing 27 tests to show what effects the rate of reaction. Diagram To make certain that this method is good enough and to certify that it worked properly we will carried out a trail experiment. We used all the average variables for fair testing. So the temperature was at room (22i ) the concentration not to strong or weak (1m) and the small marble chips. Trial experiment results 1 molar room temperature small marble chips Min/sec 1cc 1:41 2cc 3:15 3cc 4:46 4cc 6:13 5cc 7:35 6cc 9:03 7cc 10:34 8cc 11:56 9cc 13:27 10cc 14:33 The carbon dioxide was released very slowly in this test. It took over fourteen and a half minutes for it to finish and this would not be practical because of the limited time been given to conduct all our experiments. It took so long, because we had only put one small marble chip in. There were no more calcium carbonate particles to react with the acid particles, so this had a dramatic effect on the time. On In each test we do we will always place more particles than the amount we need, so there is excess calcium carbonate at the end to make sure it does not run out during the test. Because this was the first time we were trying the tests out we were a bit slow placing the bung on and maybe some of the carbon dioxide had escaped. To improve our main experiments to achieve accurate results we had to place the bung on as soon as we dropped in the calcium carbonate to make sure no carbon dioxide escaped. Results Concentration 0. 5 molar room temperature small marble chips 1st 2nd 3rd Average Temperature Room temperature 1molar small marble chips 1st 2nd 3rd AverageAnalysis On the concentration graph the average of the 0. 5m results was looked very different compared to the 1m and 2m averages. Because it took the longest time to reach 10cc of carbon dioxide, the gradient of the line of best fit sloped very gently. The release of carbon dioxide started off very slow at the being. It took 1:30 minutes to reach 1cc, then the rate quickened and in 2 minutes 5cc of carbon dioxide had been given off. On the graph the gradient in those two minutes steepened. The rate slowed down after that and the release of carbon dioxide was gradual and steady.

Keats’ Love for Fanny Brawne in The Eve of St. Agnes Essay -- Essays P

Keats’ Love for Fanny Brawne in The Eve of St. Agnes â€Å"For myself I know not how to express my devotion to so fair a form: I want a brighter word than bright, a fairer word than fair. I almost wish we were butterflies and liv’d but three summer days—three such days with you I could fill with more delight than fifty common years could ever contain† –John Keats to Fanny Brawne (Bate 538). As the colloquial phrase goes†¦behind every great man, lies a great woman, but in John Keats’ case, the woman is neither great nor his superior but inspires greatness in the Romantic poet. This woman calls herself Fanny Brawne. She was intellectually inferior to Keats, but her sprightly character added rich, sensuosity to his writing. John Keats always had a fondness for folklore and medieval tales. He dreamt of being a chivalric knight, riding on a white steed to rescue his damsel. In early childhood Keats would go to a rustic arbor, find his niche, and read Edmund Spenser’s â€Å"Faery Queen†: it â€Å"awakened his genius,† and â€Å"he was enchanted, breathed in a new world, and became another being† (Bate 75). Fanny Brawne is Keats’ â€Å"Faery Queen,† and her spirit inspires the sensuous, rife, and feminine qualities of â€Å"The Eve of St. Agnes.† Fanny Brawne and John Keats first interacted in November 1818 at Wentworth Place. He first became infatuated and entranced in her differences from himself. While distinguishing her uniqueness, John says she â€Å"liked me for my own sake and for nothing else—I have met with women whom I really think would like to be married to a Poem (Bate 428). She enjoyed literature, art, and music, but her special interest was fashion—all the sumptuous textures, colors, and styles. Joanna Richardson describes Fan... .... He has wooed with tender, sweet kisses of poetry. Keats does likewise. Since he cannot physically show Fanny her value, he arouses her with images of â€Å"lavendered† linens, â€Å"candied† confections, and â€Å"cinnamon† succulence. The verdant, active language Keats utilizes in â€Å"The Eve of St. Agnes† adumbrates his ardent love for Fanny Brawne and proves the power of poetry. Works Cited - Bate, Walter Jackson. John Keats.

Classic Pen Co. Case

Classic Pen Co. Case In the past Classic Pen Company had been the low-cost producer of black and blue pens and had profit margins over 20% of sales. Over the last five years Pen Co. decided to start producing red and purple pens. They require the same basic production technology but can be sold at 3% and 10% premium selling prices. Sales Manager Dennis Selmor is just seeing the financial results and is not happy with the numbers. The first issue that Pen Co. is facing is their decline in profitability. Even though the numbers show the red and purple pens are more profitable individually (red 14. %, purple 18. 2%), the overall return on sales is declining (13. 5%). A second issue that Pen Co. has is the issue of addition of resource costs. It requires a substantial amount of time for physical changeover of production from one colour pen to another. Particularly changing from another colour to red. The final issue Pen Co. faces is the increase of costs related to scheduling and purchas ing activities. Most of the indirect labour costs and computer system costs are related to scheduling and purchasing.Pen Company’s declining profitability could be based on the amount of the company’s overhead. They have determined overhead to be 300% of direct labour costs, when previously the overhead cost was only 200%. The make-up of this overhead is indirect labour, fringe benefits, computer systems, machinery, maintenance, and energy. The reason for such a large increase in overhead is because of the higher demand for indirect costs due to the addition of more complex and specialized products. While the cost for direct labour per one unit is the same for each colour of pen produced.The cost for indirect labour is made up of three different activities: 50% for handling production runs ($10,000), 40% for physical changeover or set up costs ($8,000), and 10% for maintaining records or parts administration ($2,000). The cost for computer systems is made up of two act ivities: 80% for production run activities ($8,000), and 20% for record keeping or parts administration ($2,000). Finally the remaining indirect costs are the machinery ($8,000), maintenance ($4,000), and energy ($2,000).These are all used to supply the machine with the capacity to produce the pens with a total of $14,000. Overall Classic Pen Co. must improve upon several areas of demand in order to increase its profitability similar to what it had been in the past. They need to increase their planning and try to adjust their current planning system and organizing. They could invest in more computers to increase the amount of scheduling being done by computers and as a result lower their indirect labour costs.Finally I recommend they should invest in some more machines to produce the different colour pens in. This would have a high cost of capital but would eventually save the company money in the labour cost and time required for the physical changeover between colours Calculation Page Indirect LabourMachine Support Handling Production Runs = 10,000Machinery = 8,000 Set Up = 8,000Maintenance = 4,000 Parts Administration = 2,000Energy = 2,000 Fringe Indirect Labour = 8,000Total = 14,000 Computer SupportFringe for Direct LabourHandling Production Runs = 8,000Fringe = 8,000 Parts Administration = 2,000 Total Overhead = 60,000 Calculating Activity Rate Activities| Activity Cost| Cost Driver #| Calculation| Activity Rate| 1) Handling PR| 22,000| 150| 22,000/150| 146. 67 / Run| 2) Set Up| 12,000| 526| 12,000/526| 22. 81 / Hour| 3) Parts Admin. | 4,000| 4| 4,000/4| 1000 / Product| 4) Machine Support| 14,000| 10,000| 14,000/10,000| 1. 4 / Hour| 5) Fringe DL| 8,000| 20,000| 8,000/20,000| 0. 4 / DL Cost| Total| 60,000| | | |

Use Of Tobacco In Australia Health And Social Care Essay

Australia has been one of the taking counties that have a great path record of baccy control. In Australia, there are around 3 million people who smoke on a regular basis between the ages of 18 to 25. The addition in baccy control strategies that increased the monetary value of baccy merchandises have changed the manner people smoke. In a recent survey, economic experts valued the nest eggs associated with avoided deceases and related diminutions in unwellness and disablement due to cut down baccy usage in Australia over the last 30 old ages at $ 8.6b ( NTS 2004 ) . The aims of the National Tobacco Strategy are the undermentioned: To assist forestall smoking uptake To assist and promote as many tobacco users as possible to discontinue smoke every bit shortly as they are able. To take exposures to harmful tobacco fume among non-smokers. If able, cut downing the harmful effects of continued usage of baccy and nicotine. Tobacco control schemes such as these increases the monetary value of baccy merchandises which changes people ‘s attitudes towards smoking through ordinances and runs that cut down baccy usage. ( NTS 2004 ) Regulation of Tobacco Promotion of Quit and Smoke free messages Cessation services and intervention Community support and instruction Addressing societal, economic and cultural determiners of wellness Tailoring enterprises for deprived groups Research, rating and monitoring & A ; surveillanceRegulation of TobaccoThe purpose of the NTS is to extinguish all promotional merchandises of baccy by those in the baccy trade, and to seek to turn to to them of the injury caused by other positive portraitures of smoke in the media.Promotion of Quit and Smoke free messagesThe purpose of the NTS is to do the wellness hazards of smoking more personal and to increase people ‘s resoluteness in discontinuing and assist them be cognizant of many effectual therapies and contact inside informations for services.Cessation services and interventionThe purpose of the NTS is to guarantee that every Australian tobacco user who are in contact with the wellness attention system are identified and be advised to discontinue, and that tobacco users who are likely to hold jobs discontinuing from smoking have easy entree to many appropriate and effectual pharmacotherapy ‘s.Community support and instructionThe purpose of the NTS to lend attem pts to forestall kids from smoke, and to guarantee that the community is intelligent about smoke.Addressing societal, economic and cultural determiners of wellnessThe purpose of the NTS is to cut down societal disaffection, along with many other negative effects by smoking and to put in baccy control as a cardinal scheme for forestalling and cut downing societal disadvantage.Tailoring enterprises for deprived groupsThe purpose of the NTS is to guarantee easy entree to many intervention, information and services for people in extremely disadvantaged groups who suffer from many smoking related injury.Research, rating and monitoring & A ; surveillanceThe purpose of the NTS is to guarantee that research is conducted to measure the demands and place utile attacks and that appropriate systems are in topographic point to measure the cost-effectiveness of plans and policies and the extent to which these are being achieved. Harmonizing to the Ottawa Charter for Health Promotions, wellness publicity actions means Building Public wellness policies, Create supportive environments, Strengthen Community actions, develop personal accomplishments, Reorient Health service and traveling into the hereafter.Build Healthy Public PolicyHealth publicity policy combines attacks including financial steps, revenue enhancement statute law, and organisational alteration. Health publicity policy now requires the designation of obstructions to the acceptance of healthy public policies in non-health sectors, and ways of taking them. The purpose must be to do the healthier pick the easier pick for policy shapers every bit good ( Talbot and Verrinder, 2010, erectile dysfunction. 4, p.266 ) .Create Supportive EnvironmentsThe guiding rule for the universe, states, parts and communities likewise, is the demand to promote them to take attention of each other, our communities and our natural environment. The demand to conserve natu ral resources throughout the universe should turns into a planetary duty.Strengthen Community ActionsCommunity development needs bing stuff and human resources in the community to better societal support and to increase public engagement in wellness affairs. This will necessitate uninterrupted entree to more information and changeless support support.Develop Personal SkillsTeaching people to larn throughout their life, to fix them to manage populating with chronic unwellness and hurts is really of import. This has been maintained at place, school, work and in the community.Reorient Health ServicessHealth services will be required to encompass an expanded authorization which is really sensitive and respects cultural demands. This authorization will be required to back up the demands of different persons and communities for a more fitter life.Traveling into the FutureHealth is created by caring for oneself and others, by being able to take determinations and have control over one â₠¬Ëœs life fortunes, and by guaranting that the society one lives in creates conditions that allow the attainment of wellness by all its members ( Talbot and Verrinder, 2010, erectile dysfunction. 4, p.266 ) .Progress/ ImprovementsIn my sentiment, the National Tobacco Strategy 2004-2009 was a well designed plan but there are still countries in the plan that needs farther betterment. The effectivity of this plan is reflected on the consequences of the figure of baccy consumption in Australia since the plan started. The NTS 2004-2009, in relation to the Ottawa Charter for Health publicities has met the demands on what wellness publicity actions truly intend such as Building Healthy Public Policy and so on. The National Tobacco Strategy 2004-2009 has built on the accomplishments of the old National trust 1999 to 2003-04, Much has been achieved by the actions of the province and district authoritiess since the early 1980s and more than 30 old ages of candidacy by non-government bureaus b ut there is still the demand for farther betterments. It was merely until 15 old ages ago ; publicities of baccy merchandises were legion. Many immature people were invariably shown legion advertizements which portrayed smoke to be merriment and made you look sophisticated. Even though the Tobacco Advertising Prohibition Act 1992 ( CDHA 2003 ) has enormously reduced advertisement through the media, many makers still continue to advance their baccy merchandises through many popular locales such as dark nines. It was merely late that the act has been reviewed and many amendments have been proposed to greatly implement limitations on current and lifting signifiers of advertisement. Adding more financess on Quit Smoking runs would assist to promote more people to discontinue smoke. This will besides increase the gross revenues of many pharmaceutical companies by promoting people to utilize their merchandises that improve the rate of people who chose to discontinue smoke. Many behavioral support services such as the state quitline now operate in many province and district but will necessitate to hold increased support if it is to manage an increasing demand from referrals from wellness professionals ; it besides needs to increase publicity in the media. Even thought there are around 80,000 people who call the Quitline in 2003 ( Kriven S, 2003 ) , but this lone nowadays a little sum of Australian tobacco users but this would besides increase if it is promoted even more. Records of baccy excise responsibility payments suggest that baccy ingestion in Australia has fallen well over the past 30 old ages since the debut of baccy control policies Among big males, smoking prevalence dropped from 45 % in 1974 to around 27 % in the late ninetiess ; among females it fell from 30 % to 23 % ( Scollo, M VCTC ) . Smoking among secondary school pupils in Australia began to worsen in the late 1980s ; it increased once more in the early to mid-1990s and declined once more at the terminal of the last decennary. The smoke around non-smokers has besides dropped significantly, with more and more workplaces censoring smoke at work. Scollo M. Annual per capita ingestion in Australia, 1903 to 2001-02.

The Olympics and the Influence of Politics In Sports Essays

The Olympics and the Influence of Politics In Sports Essays The Olympics and the Influence of Politics In Sports Essay The Olympics and the Influence of Politics In Sports Essay The Olympics and the Influence of Politics In Sports Name: Institution: Instructor: Course: Date: The Olympics and the Influence of Politics In Sports 10.1 The spirit of Olympism is based on the ideals educating people about equality and the importance of all cultures by supporting and encouraging sports as one of the humanities. This would blend culture, education and sport. Today’s Olympics have tried to keep the games aligned to these ideals, but despite a few unifying occasions, the games have veered off the original humanistic goals. One aspect demonstrating this is the increased commercialization of the Olympic events and athletes. The prominence of sponsors takes away the focus from the use of sport as an avenue for equality by promoting elitism. A few athletes are thus placed on a pedestal above other athletes. This places a focus on winning to get a result for sponsors. Personality cults also form around a few prominent athletes. The media have also played a major role in the promotion of inequality due to the aspects of the games that they choose to promote. The International Olympic committee should engage the media in promoting the importance of all athletes who make it to the games. Tokens of appreciation should also be given to all participating athletes. The excessive pressure to win has resulted in athletes using illegal means to boost their performance. The consistent discovery of doping in Olympic class athletes shows the desperation associated with winning a medal and veers off the ideals of fair play and friendship. Nationalism has also played a part in this by placing political pressure on athletes to represent their home countries well. This may later be used as leverage by countries that do well to lobby for the hosting rights of the next Olympics. Of wider significance than the games, is the festival of national representation that runs through the bidding process (Sugden Tomlison, 2012). The promotion of sports as a right to all for the joy of sport is also not a priority today. The idea of super Olympic athletes promoted by the media discourages the average person from participating in sport. It is ironical that countries that perform well in the Olympics like the United States and the United Kingdom also have high obesity rates. This can be resolved by using the Olympics as a platform to sensitize people worldwide on the importance of sport to human health and dignity. 10.2 Politics plays a highly influential role in most aspects of American sports. Of particular note, is the recent use of prominent sports personalities by politicians in the current presidential campaigns to help push for votes. Their endorsement is believed to help sway young people who place hero status on sporting legends. In addition to this, politics influences policies affecting sports on a regular basis. The National Coalition for Promoting Physical Activity is one of several organizations that lobby for Federal government funding in promoting sports for health. They also push for policies governing physical activity in America. Government agencies such as the Centers for Disease Control also institute programs like community and state physical programs besides keeping track of national physical activity statistics. The promotion of sports plays a crucial role in the creation of government policies. The Bush administration formed an advisory council on sports and physical fitness to encourage national participation in sports. The goal was to promote the overall health of Americans. Cities and states across the United States also offer financial incentives to sports facility buildings. Part of the motivation is the keep professional sports active in their cities. Numerous government policies have historically provided taxpayer subsidies and other financial assistance to various franchises in the professional sports leagues (Jozsa, 2003). The good governance in the United States promotes sports as it influences productivity in all spheres. The 2012 American Olympic team garnered the most medals. The fact that they had excellent training facilities, medical care, food and equipment, played a major role in their success. The stable political environment, made all this possible.

The KKK essays

The KKK essays The Ku Kux Klan was formed as a social club by a group of Confederate Army Veterans in Pulaski, Tennessee around 1865. A Confederate General, Nathan Bedford Forrest, was the klans first leader, whose title was Grand Wisard. White superiority was the philosophy of the Klan. And they would often use violence and terrorization of blacks as means of exercising this philosophied superiority. The Klan hated the idea of blacks getting any rights following the Civil War into the Reconstruction, and terrorized blacks to prevent them from voting in elections or practicing any other right. Blacks and white sympathizers were threatened, beaten or even murdered by the black Klan members in the South: the Klan used now familiar white robes and hoods to mask their identity.The Ku Klux Klan bacame known as the Invisible Empire as it grew and spread rapidly.(altered.com/dengue/kkk/history.html, pg1) There were social, political, and economical forces that led to the increase of the Ku Klux Klan acti vity during the 1920s. Many social forces existed that led to an increase in Klan membership in the 1920s William J. Simmons, a former Methodist preacher, organized a new Klan in Stone Mountain, Georgia in 1915 as a patriotic, Protestant traternal society. This new Klan directed its activity against, not just blacks, but any group it considered un- American, including new immigrants, Jews, and Roman Catholics. The Ku Klux Klan grew rapidly from here and had more than 2 million members by the mid- 1920s ncrease in Klan membership in the 1920s. (http://altered.com/dengue/kkk/history.html). The klan aimed to alienate non-whites and other religious groups from the rest of American society. The klan was a hate group and displayed their hatred by killing thousands of people and destroying the lives of many others The klan was based in the South, but spread their hate across America.

Racist Commenters on Mark Zuckerbergs Marriage

Racist Commenters on Mark Zuckerberg's Marriage No one has a problem with interracial marriage anymore, right? Poll after poll shows that public support of these unions is at record highs. The 2010 census revealed not only that interracial marriages are up but also that mixed-race children are the fastest growing group of young people. These days television shows feature interracial couples in storylines where race never causes tension. Altogether that means that interracial marriage is simply a non-issue in post-racial America, doesnt it? Not quite. The online reaction to Facebook chief Mark Zuckerbergs wedding on Saturday to Priscilla Chan is a clear reminder that the country has a long way to go before interracial marriage becomes widely and genuinely accepted. The day after Zuckerbergs nuptials the comments sections of websites reporting the news included several hateful remarks criticizing the couples looks and taking aim at their wealth. Thats par for the course online, though. What really stood out is the series of comments with a decidedly racial bent. On the Los Angeles Times website, a commenter named Waskoman exclaimed, Man, those mail order compaines have some hot chicks!  Just kidding!!! Another, using the moniker Jihadlives, remarked, He married a chank?   Whats up with that? What we have here is the assumption that because Chan has Chinese ancestry she cant be an American. Of course not. She must be a woman Zuckerberg shipped from overseas to be his submissive bride. In reality Chan is far from a mail order mate. Shes an Ivy League-educated doctor who could hold her own without Zuckerberg, but the facts of the situation dont easily lend themselves to racist and sexist stereotypes. The second commenter relied on a misspelled racial slur rather than on a racial stereotype to object to Zuckerbergs decision to marry Chan. On a different note, a third L.A. Times commenter accused Zuckerberg of killing his own kind by intermarrying. Ome-Coatl wrote: Why didnt he marry a nice Jewish girl?I once read a conservative Jewish commentator say that Americas intermarriage culture is destroying Jews more effectively than did the Nazi gas chambers. Perhaps it was hyperbole... or was it? The L.A. Times website was hardly the only one where racist commenters took aim at Zuckerberg and Chan. A commenter named Morney on the gossip web site Gawker applauded Zuckerbergs decision to marry interracially but for completely inappropriate reasons. He wrote, Good for Mark to marry a submissive Asian woman, instead of a spoiled American. Shes not a looker, but this way shell take care of him and raise his kids, while he can still hit much hotter #$!* on the side. Once again, theres the assumption that Chan is not from the United States, as if Asian Americans dont exist. This commenter also assumes because Chan has Chinese heritage shell be content to serve as Zuckerbergs caretaker (instead of the doctor she studied to be) and will be so passive shell be cool if Zuckerberg cheats on her. On Gawker, a couple of commenters tried to show Morney that not all Asian women are passive, but they did so by invoking the Dragon Lady stereotype. Youve never dated an Asian woman have you? commenter Tsol asked Morney. Especially a driven achiever like Priscillathere is nothing submissive about them. In fact I guarantee that shes the one wearing the pants in that relationship. Theres a reason the Dragon Lady stereotype stills exists. A word to the wise: you dont fight a stereotype by mentioning another stereotype. Just as all Asian women arent submissive, all Asian women certainly arent domineering, so no one can guarantee that Priscilla Chan wears the pants in her relationship with Zuckerberg. As for why racial stereotypes still existits because racism still does. On TMZ.com commenters plainly suggested that Chans Asianness makes her a whore. Bet she love him long, long time, a commenter named Really? quipped. Others followed suit, and the scary thing is that a number of these comments received more favorable ratings from other viewers than unfavorable ones. So, who cares if racist commenters dont like the fact that Mark Zuckerberg married a Chinese-American doctor? He could buy and sell everyone of those haters. That may be true, but if people exhibit this level of racial animus concerning a powerful couple they dont even know, imagine how people regard the interracial couples they pass on the street, live next to or are related to? Its also important to note that interracial couples consisting of a white man and an Asian woman are largely regarded as the least threatening of all. Given this, if Zuckerberg and Chans marriage can stir up this much hate, what must interracial couples with a different ethnic makeup endure?

Bureaucracy Essay Example | Topics and Well Written Essays - 1000 words

Bureaucracy - Essay Example These concepts include, hierarchy, jurisdictional competency, command and control, technical expertise, and system of rules, and written documentation. An organizational hierarchy is the â€Å"arrangement of the organization by level of authority† in reference to the ranks above and below it (Grimsley 2014, para. 6). This therefore implies that in bureaucracy, there is existence of certain levels of authority ranging from the top level management to the normal employees. For instance, in a company a sales marketing director is below the overall chief executive officer (C.E.O), at the same level with the advertising marketing director and above the secretary. Therefore, this system dictates that each level should answer to the rank above it with the ultimate leader of the company at the very top of the hierarchy. Jurisdictional competency is another key concept of bureaucracy. Fundamentally, huge roles are broken down into smaller and simpler tasks which are then assigned to employees throughout the organization. This division of labor across the organization enables employees to master the skills and details of repetitive duties thereby increasing efficiency. However, though the division of labor could be highly proficient, â€Å"it can lead to a number of harmful organizational pathologies† (Rockman 2013, para. 5). This implies that division of labor could at times turn out to be ineffective due to a number of reasons. For instance, employees can be unable to adequately respond to problems outside their areas of jurisdiction, and may approach them from their own perspective. This could lead to an overall destruction of the organization’s performance. Command and control is another key feature of bureaucracy that weber discussed. Due to the fact that a bureaucratic authority is organized hierarchically, â€Å"responsibility is taken at the top and delegated with decreasing discretion at the lower levels of the organization† (Rockman 2013, para.

How does Harold's article on The Sopranos either complicate or further Essay

How does Harold's article on The Sopranos either complicate or further the arguments put forth in Garrett's text about TV Anti-Heroes and what they represent in our society - Essay Example This argument has been furthered by â€Å"A Man Never Never Land†, this is because the article postulated that the heroes of today have colossal psychological flaw; this is because they have a self-serving lies. They are normally filled with self-pity, venality, sloth, and lust. They are regarded to be self-deceiving and morally blind. Additionally, they are deemed obnoxious, unfaithful, and brash. This is supplements the argument of Garrett which that â€Å"We live in Post-World War II era†. According to Tony Soprano, the issue of morality was white and black; it was compared to Nazis vs. us. The Nazis were rated as bad people. However, in the war of today, the wrangles and conflict are ambiguous, including using torture. â€Å"A moral Never Never Land: Identifying with Tony Soprano† argued that people now have to employ morally unacceptable mechanism of fighting terrorists and the moral ambiguity is engraved in the upcoming anti-hero. Harold further explains that to add to the heroes that were heavily flawed, there are pressure from the prison system, big business, bureaucracy, and the structure of power that is full of bribe in conforming to forces that are not good. Rather they have rebelled against themselves, even if using the trickery a nd dishonesty could be portrayed as heroic. â€Å"A moral Never Never Land: Identifying with Tony Soprano† further argues that there is confidence crisis in the democratic leaders and processes that created a surrounding of nihilistic, disaffected, and cynical hero. This turning point during the Morally Deformed Hero Regime, happened with â€Å"A moral Never Never Land: Identifying with Tony Soprano†, when millions of people loved him. The ruthless sociopath and businessperson became close that the moral boundaries blurred in the regime of the hyper-competitive Darwinism. In the docket, both Nazis and Us failed in effecting the change in

Global Warming is Media Hyped Hysteria Essay Example | Topics and Well Written Essays - 500 words

Global Warming is Media Hyped Hysteria - Essay Example The first article has been published by an environmental agency and therefore, it has used ethos in its writing to convince the readers. The use of scientific explanations and relevant theories are used to explain the drastic ramifications of global warming. ‘trading program would harness American ingenuity to decrease heat-trapping pollution, cost-effectively..’(EDF). The Second article, on the other hand, is a speech by a political leader and therefore, one is able to find the text full of pathos and logos to sway the public perception. Inhofe has cleverly used creative imagery and mental images to provide a relatively coherent explanation for his arguments. ‘Advocates of alarmism have grown increasingly desperate†¦Ã¢â‚¬â„¢ (Inhofe). The first article lacks emotional appeal and relies heavily on scientific facts which are stark in their explanation and therefore, fail to impress the common man. Inhofe, on the other hand, has combined logos in his pathos. Citing previous press releases, Inhofe’s rhetoric of the discourse was designed to inflame the feeling of outrage against the media hype and has asked ‘if CO2 is the driving force for global climate change, why do so many in the media ignore the many skeptical scientists who cite these rather inconvenient truths?’. The structured and well laid out article has tried to explore the issue through the myths that are common among the masses but the lackluster style has failed to convince the masses because it is not tempered with modules that have a significant impact on human emotions. Inhofe has shown that facts and figures need to be used in a manner that it can impact the human psyche through clichà ©s and metaphors. â€Å"’60 Minutes’ failed to inform its viewers that a 2005 study by Ola†¦.that the interiors of Greenland are gaining ice and mass and that†¦ The Arctic was warmer in the 1930s than today†.  

Performance Measures Research Paper Example | Topics and Well Written Essays - 750 words - 2

Performance Measures - Research Paper Example Forensic Psychology is understood as a mixture of both psychology of the brain and the legal psychology in any given location. The field is important in that it assists in the assessment and the understanding of people that may be diagnosed with a mental condition and involved in crimes (Ryan, 2007, 98). The field developed after the acknowledgement of the fact that many people had been sent to prison and were not in the proper state of mind. This has had scientists involved in finding means through which these sick people can be sent to mental institutions for the resolution of their issues other than send them to prison to suffer. This is from the fact that they do not deserve a sentence and their mental conditions should stand up in court. Diversion is a major part of Forensic Mental Health (Samuels, 2011, 167). This is a term that is used to refer to the change of custody of a patient with extreme mental conditions from the legal Justice System and straight to the health system for assistance. Psychosocial issues have been of great importance with relation to forensic mental health. Psychosocial issues are the ones that relate to the mind in a psychological manner and thus directly link to Forensic Mental Health. Most of these issues involve the engagement of various job descriptions and locations in an effort to assist people with severe mental conditions. Association of the community with these mentally impaired people is very important for the maintenance of the patient’s character (Candice, 2010, 109). This is a major psychosocial issue in that when these people do not feel at ease with the person, he begins having ideas that he is all alone and that nobody is interested with his company. This may put the person in a worse mental state and drive him to committing another crime of which the justice system does not act on as leniently as the first case. Another sector that has a big role to

Human Resource Management regarding Coca Cola Company Essay

Human Resource Management regarding Coca Cola Company - Essay Example The personnel management accentuates the transactional leadership style where the leader is not viewed as a job-oriented individual. In this style of management, focus is directed at set procedures, completion of duties, and punishment for not performing or complying with the rules. Human aspects like consideration, concern, lenience, and personal relationships attract less attention. Human resources management, however, creates transformational leaders. This style of management seeks to promote the sharing of business goals by both management and employees. This management is workforce oriented and shares the objectives of the business with its employees. The second distinction is that in personnel management the job plan is functional. Pay policies are not based on ability and information. The value in this management is based on the duties outlined in the contract only. The human resources management encourages workforce to view the pay as a motivation to improvement of job perfor mance. The job design focuses on teamwork, job rotation and enlargement as an approach created by the human resources manager. Third, the personnel management ensures that personnel strictly follow the contract of employment. This style of management allows no room for modifications or changes in the contract outline. The human resources management employs a flexible approach to the workforce that entails open contract agreements. The employees granted the freedom to choose working systems that suit them. This style ensures that the employees are free hence more input leading to the benefit of the organization (Ster & Koster, 2007, p. 6). This style is referred to as a win-win approach. The nature of relations is also different because in the personnel management the relationship is contractual. In this management one individual hires whereas the other one performs. The human resources management focuses on sharing mission and vision associated with the achievement of the organizat

Human Resources Management in the Navy and Marine Corps Term Paper

Human Resources Management in the Navy and Marine Corps - Term Paper Example Strategies like Sea Power 21 and Marine Corps Strategy 21 are being used to define the paths to meet future uncertainties emerging from the rapidly changing global environment. In order to overcome the emerging challenges the naval operations must be technologically armed through scientific and technological innovations. The army is required to improve its tracking mechanism in rightly identifying terrorist operations with considerable accuracy and thereby to act promptly. In turn the strategic levels concerning tactical, operational and strategic operations with the support services create further development of the army personnel. The naval personnel operating along the above lines are thereby required to exhibit higher amount of competencies, be much aware to the changing situations and to act accordingly. To sum up the modern naval force needs to speed up their activities, be flexible to the changing environment and must be accurate and sure in countering such. Hence, the process es built during the cold war era in the naval system are observed to have become outdated. Thus emerges the need for a newer process known as Naval 21. (England, 2003) The paper in this light aims to highlight the changes in human resource practices in United States Navy and Marine Corps on a wider plane. The Human Resource Management Operations in the United States Navy require sea changes in respect to some key areas. In regards to Workforce Structure it is observed that in the current system the structure is hierarchical. The model was developed to fit in all situations. However, the Naval 21 Model emphasizes in the creation of a flat organization. It states that the flat organization would help in empowering employees with increased responsibilities. Moreover, the technology used in the Human Resource Operations currently is observed to be fragmented. The deployment pattern of the fragmented technology is found to be slow in pace. Thus the Naval 21 Model

Reusability of Code Essay Example for Free

Reusability of Code Essay Reusability of codes general purpose is to reduce unnecessary coding which in the end reduces project development time and funds. It is essentially taking code from one part of a program and attempting to employ it elsewhere without having to alter too much. This method is similar to reusing software mechanisms in object-oriented programming. Object-oriented programming and procedural programming are two programming paradigms that distribute common attributes as well as various differences. A procedure is an additional name for a routing, technique or function. Procedures and objects both use algorithms to develop the system and any logical calculation that is necessary for the program. A function is divided from variables and data compositions. Procedures are intended to run the code in a precise order, while OPP merges data with the function in the function changes the data that is bound to it into a unit identified as an object. Other useful features such as abstraction, encapsulation, and inheritance can be achieved while working with OPP. Procedural Programming The earliest programming languages were procedural, meaning a program was made of one or more procedures. A procedure is simply a module or function that performs a specific task such as gathering input from the user, performing calculations, reading or writing files, displaying output, and so on. The programs that you have written so far have been procedural in nature. The steps a program must perform to reach the desired outcome. Procedure is an independent entity and a sequence of instructions that are grouped together. In procedural programming, a task is broken down into assortment of variables and subroutines. In OPP, a task is broken down into objects which summarize the data and execution. In a procedural approach, the entirely called variable is termed as a trait of the object. The idea is to encapsulate data and a technique into what is referred to as a class. A class is a model; a class can be used to make several objects. This allows code be reusable in OPP. Object-Oriented Programming Object-oriented programming (OOP) is centered on creating objects. An object is a software entity that contains both data and procedures. The data contained in an object is known as the object’s fields. An object’s fields are simply variables, arrays, or other data structures that are stored in the object. OPPs group the data methods together so that each can operate on its own data while procedures are used to directly perform operation on data structures. OPP provides encapsulation making class whose objects can be created dynamically. OPPs have been observed to give lower quality performance as compared to procedural programming. In addition to solving the problems of code-data separation, the use of OOP has also been encouraged by the trend of object reusability. An object is not a standalone program, but is used by programs that need its service. (Gaddis, 2010) References Gaddis, T. (2010). Starting out with programming logic and design. (2 ed.).

Formaldehyde: History and Importance

Formaldehyde: History and Importance 1.0INTRODUCTION Formaldehyde is the first member of the aldehyde family (CH2O) and is the most important aldehyde in the environment.3 It is a naturally occurring chemical and a by-product of most organisms, including human, industrial and natural processes. Formaldehyde forms from the incomplete combustion of carbon-containing materials; smoke from forest fires, in automobile exhaust, and in tobacco smoke. Atmospheric formaldehyde is formed by the action of sunlight and oxygen on methane and other hydrocarbons.2 Due to its simple nature, metabolic processes break formaldehyde into carbon dioxide. Formaldehyde does not accumulate in the environment or within plants, animals or people, as it quickly breaks down in the body and the atmosphere.1 It has a pungent odour and is an irritant and is an irritant to eyes, nose and throat, even at low concentrations. The recommended odour detection limit is between 0.05 1ppm.3 Formaldehyde is an important industrial chemical and is employed in the manufacture of many industrial products and consumer articles. More than 50 branches of industry now use formaldehyde, mainly in the form of aqueous solutions and formaldehyde-containing resins. In 1995, the demand for formaldehyde in the three major markets Northern America, Western Europe, Japan was 4.1ÃÆ'-106 t/a [Chem. Systems Inc.: Formaldehyde (April 1996).]. History of Formaldehyde Research in the early 1800s by Liebig discovered the chemical composition and nature of various aldehydes excluding formaldehyde due to the ease with which methanol was oxidized to formic acid and further synthesized to carbon dioxide and water.5 In 1859, Alexandra Mikhailovich Butlerov inadvertently discovered formaldehyde as a result of his proposed synthesis of methylene glycol [CH2 (OH)2]. During his laboratory experiment, Butlerov observed the distinctive odour of the formaldehyde solution while hydrolysing methylene acetate, which decomposed to form formaldehyde and water. 5 He also produced formaldehyde in other forms which led him to publish a detailed report of formaldehyde solution, its gas and polymer. He gave additional evidence of its structure and described the chemical reactions together with the creation of hexamethylenetetramine, [(CH2)6N4] on reacting with ammonia, (NH3). The main way by which formaldehyde is still being produced till date was discovered by A.W. Hofmann but with other catalysts. In 1868, Hofmann made a successive breakthrough by passing a mixture of methanol and air over a heated platinum spiral. This process is currently industrialised by use of a metal catalyst. Over two decades later, the isolation and purification of formaldehyde was achieved by Friedrich Von Stradonitz (1892). 4 1882 marked two significant improvements in formaldehyde research. Kekule then described the preparation of pure formaldehyde and Tollens discovered a method of regulating the methanol vapour: air ratio, thereby affecting the yield of the reaction.6 The spiral platinum catalyst was replaced with more efficient copper gauze in 1886 by Leow. Commercial manufacture of formaldehyde was initiated by a German firm, Mercklin and Losekann in 1889 with the first use of silver catalyst patented by Hugo Blank, another German company in 1910. 6 Industrial development continued from 1900 to 1905, when plant sizes, flow rates, yields, and efficiency were increased. In 1905, Badische AnilinSoda-Fabrik (BASF) started to manufacture formaldehyde by a continuous process employing a crystalline silver catalyst. Formaldehyde output was 30 kg/d in the form of an aqueous 30 wt% solution. The methanol required for the production of formaldehyde was initially obtained from the timber industry by carbonizing wood. The development of the high-pressure synthesis of methanol by BASF in 1925 allowed the production of formaldehyde on a true industrial scale. 6 Importance of Formaldehyde For several decades, formaldehyde has been used consistently in a wide range of products, ranging from personal hygiene, to medicine, to building products and much more. Many different resins are created from formaldehyde, which are in turn used to create other materials having different properties. Formaldehyde derivatives are used as preservatives in personal hygiene products because they kill bacteria or they are used to make other products more effective in terms of foaming action such as soaps and detergents. Its versatile chemistry and unique properties have created applications for use of formaldehyde in all kinds of every day products such as plastics, carpeting, clothing, resins, glues, medicines, vaccines and the film used in x-rays. One of the first benefits you derive from formaldehyde chemistry is as a child, when you received your vaccinations for childhood diseases. These include diphtheria, polio and influenza, to name a few. Since it also acts as a preservative, formaldehyde plays a critical role in our medical schools, preserving cadavers used in teaching human anatomy. It has been used for tissue and organ preservation for more than a century and has greatly assisted the advance of biological science.1 Importance of Green Processes The concept of Green Chemistry helps reduce or eliminate the use or generation of hazardous substances in the design, manufacture and application of chemical products. This helps in dealing with the ever growing increase to protect the environment and the concept of sustainability. A lot of emphasis is based on the research and development phase of each chemical or product, to curtail issues affecting human health and environmental pollution. For every chemical or given product, the following guidelines should govern the choice of route:7 * Choice of feed-stock (costs are relevant of course, but also total resources, energy, waste, etc. in the manufacture of the given feed-stock are important factors) * Choice of reaction path (minimise energy requirements by use of selective catalysts) * Choice of catalyst (efficiency, separation from product, recycling of catalyst) * Down-stream processing/unit operations (minimising the number of stages necessary to obtain the product in the state desired by the customer) * Minimising not only the amount pollutants, but also the volume of waste streams (effluent/ off-gases and solid waste) * Recycling of auxiliary, side-, and intermediate products into the process. This report focuses on physical and chemical properties of formaldehyde (CH2O), its production processes and evolution through time as it tries to conform to some of the principles of green chemistry. 2.0PROPERTIES OF VARIOUS FORMS OF FORMALDEHYDE Formaldehyde is more complicated than many simple carbon compounds because it adopts different forms. Formaldehyde is a gas at room temperature, but the gas readily converts to a variety of derivatives. These derivatives generally behave similarly to gaseous formaldehyde and are used in industry.4 Physical Properties I. Monomeric formaldehyde: This form of formaldehyde [50-00-0], CH2O is a colorless gas that has a foul, overpowering odour and is an irritant to eyes, nose, throat and skin. Monomeric formaldehyde liquefies at -19 °C, and solidifies at -80 °C to give a white paste. The liquid and gas phases polymerise readily at low and normal temperatures up to 80 °C. Pure formaldehyde gas, on the other hand, does not polymerise between 80 100 °C and behaves as an ideal gas. Though it is not commercially available in this form, it can be prepared in the laboratory by the Spencer and Wilde method.6, 3 The molecular formula of gaseous formaldehyde in ambient air is shown below. II. Trioxane: 1, 3, 5- Trioxane is a stable cyclic trimer of formaldehyde, C3H6O3. It appears as a white solid with a chloroform-like odour but does not cause any form of irritation to living things. The pure form of trioxane melts at 61 62 °C boils at 11 °5C and has a flash point of 45 °C. Trioxane is used as a feedstock for some plastics, solid fuel tablet formulas and as a stable source of formaldehyde in laboratories.8, 3 III. Paraformaldehyde: this is a colourless, granular solid with a pungent and irritating smell. It is prepared by condensation of methylene glycol (HOCH2 OH), and its composition is best expressed by the formula HO- (HCHO) Q-H. Paraformaldehyde melts over a wide temperature range (120-170C), which depends on the degree of polymerization. It has similar uses to formaldehyde; it is commonly used as a source of formaldehyde for disinfecting large areas.3 IV. Formalin: The primary market for formaldehyde is in aqueous form, Formalin. It is a clear solution with the characteristic odour of formaldehyde. Methanol is normally present, 6-15%, to suppress polymerisation. In aqueous phase, the dominant form of formaldehyde is methylene glycol and polyoxymethlene glycol for concentrated solutions.3 Chemical Reactions of Formaldehyde I. Decomposition: In thermal decomposition, formaldehyde is relatively stable. At 150C, formaldehyde undergoes heterogeneous decomposition to form methanol and carbon dioxide. Above 350C, the reaction decomposes to form carbon dioxide hydrogen. Catalysts such as platinum, copper, chromium and aluminum are involved in this decomposition reaction to form methanol, methyl formate, formic acid, carbon dioxide and methane.6 2HCHO à ¢Ã¢â‚¬  Ã¢â‚¬â„¢CH3OH+CO HCHO à ¢Ã¢â‚¬  Ã¢â‚¬â„¢CO+ H2 II. Polymerisation: At room temperatures and very low pressures, formaldehyde monomer vapours tend to polymerise while at higher temperatures, monomeric HCHO can be maintained readily for several hours without polymerisation at an equilibrium vapour pressure. In the aqueous phase, formaldehyde is oxidized readily by even mild oxidizing agents, such as Ag(NH3)2+, and this property has been exploited in the development of several wet-chemical analytical methods for formaldehyde.3 III. Reduction and Oxidation Reactions: Formaldehyde is readily reduced to methanol with hydrogen over a nickel catalyst and is oxidized by nitric acid, potassium permanganate, potassium dichromate or oxygen to form formic acid or carbon dioxide, and water.6, 3 A Cannizzaro reaction occurs when formaldehyde reacts with a strong alkali or heated acid to form methanol and formic acid. HCHOaq+ NaOH à ¢Ã¢â‚¬  Ã¢â‚¬â„¢HCO2Na+ H2 H2+ HCHOaq à ¢Ã¢â‚¬  Ã¢â‚¬â„¢CH3OH In the presence of aluminum or magnesium methylate, paraformaldehydes react to form methyl formate. This is known as the Tischenko Reaction. 2HCHO polymerà ¢Ã¢â‚¬  Ã¢â‚¬â„¢HCO2CH3 IV. Addition Reactions: V. Condensation Reactions: Formaldehyde is a base product in many synthetic resin product.9 Formaldehyde condenses with urea, melamine, urethanes, cyanamide, aromatic sulfonamides and amines, and phenols to give a wide range of resins; Amino, Phenolic and Synthetic Resins.6 3.0METHODS OF PRODUCING FORMALDEHYDE Over the years, the starting feedstock for the commercial production of formaldehyde is Methanol. This feedstock has been produced by reacting carbon monoxide and hydrogen, both usually from natural gas or petroleum fractions, under high pressures in the presence of a catalyst.3 Various patents have been published for the production of formaldehyde but most with no commercial importance. Of all these, the procedure to be discussed is the reduction of carbon monoxide. 3.1Reduction of Carbon Oxides This process has been put through a lot of research due to its low cost of raw materials and potential simplicity. The end-product of this reaction is usually methanol with formaldehyde as an intermediate in the reaction. This process is a two-step reaction; part of the reaction is a simple hydrogenation process and the other, by the Cannizzaro reaction of formaldehyde with itself. The reaction with copper-alumina catalyst forms formaldehyde at temperatures of 282 487 °C and pressures of 117 410 atmospheres.10 CO+ H2 à ¢Ã¢â‚¬  Ã¢â‚¬ CH2O This reduction reaction is highly unfavorable as a means of formaldehyde synthesis due to the following reasons. * Unreasonable high pressures required to obtain high yields * To obtain equilibrium at a reasonable rate and avoid hydrogenation, an extremely active and selective catalyst would be required. 3.2Methanol and Formaldehyde Formaldehyde is industrially manufactured with methanol through three main processes.6 1. Partial oxidation and dehydrogenation with air in the presence of silver crystals, steam, and excess methanol at 680 720 °C (BASF process, 97 98 % methanol conversion). 2. Partial oxidation and dehydrogenation with air in the presence of crystalline silver or silver gauze, steam, and excess methanol at 600 650 °C (77 87 % primary conversion of methanol). The conversion is completed by distilling the product and recycling the unreacted methanol 3. Oxidation only with excess air in the presence of a modified iron molybdenum vanadium oxide catalyst at 250 400 °C (98 99% methanol conversion). Process 3, also known as the FORMOX process, a highly exothermic process, occurs at temperatures of about 350 °C. Though this process uses lower temperatures and a cheaper catalyst, the dehydrogenation process is still prevalent in the industry because of its lower operating costs.2, 3 Production of formaldehyde via conversion of propane, ethylene, propylene, butylene, ethers and butane are not economic therefore have little or no industrial relevance. In addition, the partial hydrogenation of CO and methane oxidation results in lower yields as compared to the former processes.6 3.3Development of the Methanol Process The initial method for the development of formaldehyde was originated from by Hofmann, which is the passing of a mixture of air and methanol over a heated platinum spiral and dissolution of this product to form aqueous formaldehyde, formalin.10 This process was replaced due to difficulties with explosions in completing the product recovery. Subsequent development involved the replacement of the platinum catalyst with platinised asbestos in a heated tube by Volhard. Further research by Tollens introduced the direct relationship between the methanol-air vapour ratio and the formaldehyde yield; which is still a main principle in todays industries. 10 Leow refined the two later processes by replacing the platinum catalyst with copper gauze. This initiated the first continuous process for formaldehyde production. The first stage of this process yielded about 15 20% formaldehyde, with an additional 30% conversion due to further heating of the reaction gases. 10 Though not aware at the time of the concept of green chemistry, research was carried out covering the preparation of catalysts, reaction times and temperatures, and product absorption during the early years of commercial development of formaldehyde. This led to technological development for the use of a silver catalyst by O. Blank in 1910. Thorough investigation with the use of this catalyst proved that higher yields were obtainable as to that of the copper catalyst. 10 Large scale manufacturing welcomed improvements in the method for vapourising alcohol, the scrubbing systems and in the control of the heat of reaction. The copper gauze was observed to disintegrate or fuse together with high air-methanol ratios. To tackle this issue, low ratios were introduced to help keep the catalyst active but this resulted in excess methanol distilled from the formaldehyde. 10 The progress made throughout the years has been achieved by the following: * Efficient catalysts * Improved methods of control * Implicit engineering economies 3.3.1Silver Catalyst Process This route is the classic method for the industrial production of formaldehyde. The two main reactions governed by this process are dehydrogenation and partial oxidation. The dehydrogenation of methanol is a highly endothermic, 650 °C, and heat of reaction is usually obtained from the burning of the hydrogen enclosed in the flue gas. These processes are usually carried out by reacting methanol and air over a heated stationary catalyst and scrubbing the off gases with water to obtain aqueous formaldehyde. 6 Addition of inert substances, water or nitrogen, aids conversion by using higher methanol concentrations relative to the oxygen supplied without reaching the explosive phase. A few key reactions take place during methanol conversion to formaldehyde. 3 CH3OH à ¢Ã¢â‚¬ ¡Ã¢â‚¬Å¾CH2O+ H2 à ¢Ã‹â€ Ã¢â‚¬  H= +84kJ/mol H2 +12O2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ H2O à ¢Ã‹â€ Ã¢â‚¬  H= -243kJ/mol CH3OH+12O2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CH2O+ H2O à ¢Ã‹â€ Ã¢â‚¬  H= -159kJ/mol Methyl formate, methane and formic acid are important by products of the above reactions. Below are a few undesirable reactions that must be avoided by proper control of temperature and other factors to obtain high yields. CH2O à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CO+ H2 à ¢Ã‹â€ Ã¢â‚¬  H= +12.5kJ/mol CH3OH +32O2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CO2+ 2H2O à ¢Ã‹â€ Ã¢â‚¬  H= -674kJ/mol CH2O +O2 à ¢Ã¢â‚¬  Ã¢â‚¬â„¢ CO2+ H2O à ¢Ã‹â€ Ã¢â‚¬  H= -519kJ/mol The usual process for the commercial production of formaldehyde is through the incomplete oxidation of the methanol. So far, this has been proven to be the most optimal process because the distilled methanol is recovered and recycled in the process. This results in higher yield, higher conversion and a high atom economy. 6, 10 The BASF Process This process involves the complete conversion of methanol to formaldehyde (Reaction 1). This process indirectly applied some of the principles of green chemistry. 6, 10 1. Few reaction steps 2. Recycling of materials within the production system to optimise product recovery resulting in a very high atom economy. 3. Environmental awareness with combusted off-gases having no adverse effect on the environment 4. The use of water as a solvent 5. Incorporation of all materials in the process, maximizing final product with extremely low weight percent of by-products formed 6. Optimum surface reaction with arrangement of catalyst 7. Process conditions adjusted to ensure that in retrieving of the final product, the mixture is easily stripped without scare of an explosion. Incomplete Conversion and Distillative Recovery of Methanol In this process, methanol is partially oxidised and distilled to recover formaldehyde. This is the most widely used method of production. It should be noted that an economically feasible process is not necessarily a green process. Partial oxidation of methanol has similar characteristics but differ with the following with respect to green chemistry. 6 1. Two-stage reaction 2. Lower reaction temperatures adopted in the first stage to help suppress the formation of unwanted by-products. 3. Heat of reaction generated from cooling the off gases, recycled in the system reducing energy requirements. 4. Larger amount of methanol is recovered in this process with little presence of the b-products 5. Similar off-gases as produced in the BASF process 6. It also has an alternative route that recycles the tail gas from the top of the absorber. This reduces the amount of feedstock, methanol, required in the process. This produces a more concentrated solution and saves up cost for the distillation process and the yield is relatively high (91-92%). Factors affecting the yield in methanol oxidation processes * The higher the temperature in a dehydrogenation reaction, the higher methanol is converted in the process system. 10,6 * Process air controls the desired reaction temperature and the extent to which the endothermic reactions occur. 10,6 * Besides catalyst temperature, the inert materials added as stated earlier also affect the yield. 10,6 Some of the advantages of the silver catalyst process are listed below:11 * Most cost effective means of manufacturing formaldehyde * Increased formaldehyde yield, methanol conversion and catalyst life * Reduced silver requirements * Greater resistance to plant upsets and poisoning * Improved formaldehyde product quality * Technology demonstrated worldwide 3.2.2FORMOX Process The FORMOX process is the direct oxidation of methanol with metal oxide catalysts (iron, molybdenum or vanadium oxide) to produce formaldehyde. Normally, the catalyst used for this process is a mixture of molybdenum and iron in a ratio of 1.5:2.0. Due to the development of this catalyst, a few advantages have been attributed to this process over the silver catalyst processes. This will be discussed in the later part of this report. The FORMOX process can be characterised as follows: 1. Two stage oxidation reaction in gaseous state. This prevents waste that would have been generated by use of a solvent.6 2. Reaction carried out under atmospheric pressure and at lower temperatures (270 400 °C), results in an almost complete reaction. 6 3. Careful adjustments of process conditions help prevent the formation of unwanted by-products. These side reactions occur at temperatures exceeding 470 °C. 6 4. The conversion rate for this process is relatively high with a high optimization process. 5. One short-coming of this process is with the tail gas that has lots of impurities and flammable components. The alternative route used instead of combustion is in the addition of fuel to the system which burns the tail gas as a supplement for energy in other start-up processes. 6 In summary, the green advantages of the three commercial processes can be summarised as follows: 7 1. Few unit operations 2. Waste is minimised by a highly selective reaction 3. Use of catalysts to optimise process reactions 4. Water used as the only solvent 5. Reaction carried out at atmospheric pressure 6. Gas-phase reaction for the FORMOX process means that catalyst does not have to be recovered from solution 7. Recovery of energy from exothermic reactions to help reduce environmental and economic impacts. 8. High conversion rates achieved through efficient use of equipment, energy and material 9. Use of air as oxidant instead of chemical oxidising agents reducing the toxicity and by-products formed. 3.3Development of New Processes Various research works have been carried out for developing new formaldehyde synthesis. Unfortunately, there has been no existence of commercial units of the techniques discussed below: 1. Partial oxidation of methane to produce formaldehyde which has an advantage of reducing raw material costs of producing the methanol from methane. The inducement for such a process is reduction of raw material costs by avoiding the capital and expense of producing the methanol from methane. 12 2. Production of anhydrous or highly concentrated formaldehyde solutions via dehydrogenation of methanol. In some instances, energy costs are reduced as well as effluent generation, and losses, providing a more favorable condition. 12 3. Formaldehyde production from methylal (produced from methanol and formaldehyde) which is in two phases. Firstly, methylal oxidation which yields up to 70% of the concentrated formaldehyde product as compared to methanol oxidation with 55%. After this, methylal is produced by reacting formaldehyde obtained in aqueous recycle streams from other units with methanol as opposed to recovery by other more costly means, e.g. distillation and evaporation. Development of this process is complete. 12 Further research is still being carried out in the use of bacteria to produce formaldehyde. This will not be discussed in this report. 4.0ENVIRONMENTAL ISSUES ASSOCIATED WITH FORMALDEHYDE REFERENCES 1. Formaldehyde Council, I. (2007, November).

Singaporean Mentality Exposed :: I Not Stupid Education System Essays

Singaporean Mentality Exposed Film critics and audiences have dubbed I Not Stupid an excellent commentary on the education system and government paternalism. The movie stars three school children who have been channelled into the undesirable EM3 stream, and shows the trials and tribulation of these children and their parents. I Not Stupid has been described as a "coming of age movie"1 for its rare ability to criticise the government and its policies and bring pertinent issues to light, so much so that many are surprised that it managed to get past the not-too-kind local board of censors. This presents us with an interesting question - with its explicit references to the government and its blatant criticisms of government policies, how did this political satire get past the censorship board? Was it a case of the censors deciding that this sort of criticism was acceptable once in a while? Or perhaps the censors just saw the movie differently. At first mention, the latter might sound very unlikely. However, if we ask ourselves what the real butt of the satire is, we might begin to realise that there is a possibility that this movie is not intended to be a political satire at all. In fact, it is my contention that the butt of the satire in this movie is the Singaporean mentality, and not the government. However, before we can begin to examine the real target of the movie's satire, it is first necessary to have an understanding of the movie and its characters. The movie stars three students, Terry Khoo, Liu Kok Pin and Ang Boon Hock who are in the EM3 stream. Terry Khoo, who is also the narrator in the movie, is portrayed as a chubby and clumsy spoilt brat, whose mother is overly paternalistic. Mrs. Khoo, who is decked in white for most of the movie to no doubt show a similarity between her and the PAP government who also have a white uniform, makes all the decisions for her children, and believes that they should be lucky to have such a responsible mother. While Terry is happy to accept this situation, his elder sister Selena is more rebellious and repeatedly demands her freedom. Liu Kok Pin is a student whose ability in English and Maths is weak. His mother, Mrs. Liu takes it upon herself to discipline Kok Pin to ensure that he scores well in his tests in school, while brushing asi de his natural talent in art.

Aristotle and the Realm of Ethics

An examination of the Nichomacean Ethics is a task that contains the dichotomy of examining Aristotle’s simple, basic definitions along with the great complexity that is present in the underlying meaning behind the simplicity. Aristotle believed the ultimate goal of a human being was (is) to seek happiness and that only a virtuous person can truly achieve happiness.   The acceptance of these notions centers on the perception of the definitions of â€Å"virtue† and â€Å"happiness†. In Aristotle’s words, â€Å"We are now in a position to define the happy man as one who is active in accordance with complete virtue.†Ã‚   In other words, happiness without ethics is a near impossibility.. Eudemonia is a particularly complex situation when trying to understand the importance of it in regards to ethics because eudemonia generally refers to â€Å"happiness or pleasure.† Unfortunately, as the history of human behavior has shown, there will be those individuals who derive their happiness from actions that can be somewhat harmful to people. This type of behavior is, essentially, a pleasure principle based on perversion as opposed to one that is based on ethical behavior. So, it becomes important to separate Eudemonia from perversion or anti-social behavior in because, ultimately, while there may be some pleasure present in such conduct, this does not lead to overall happiness because there might exist a situation where such behavior leads a person down a road of a damaged life. Drugs may bring happiness, but this will exist only for the short term. Ultimately, they will lead to a damaged life that is devoid of happiness. As such, the happiness that Eudemonia  represents must not be transitional happiness, but happiness that is everlasting. In order to achieve this, the happiness must be based on ethical approaches to the pursuit of happiness. Ultimately, virtue breeds ethics and a disposition that is virtuous will further perpetuate ethical behavior. The reason for this is simple: a person who acts with purity can not act unethically as a lack of ethics and a preponderance of virtue are, essentially, mutually exclusive. A disposition of virtue will, in effect, cancel out any unethical or immoral behavior. Now, a virtuous person can also be a person who is rife with internal conflict. To seek happiness does not mean that the person will achieve happiness no matter how hard he or she tries. Often, there will be conflicted internal struggles that pit virtue, honesty and â€Å"the good life† against the frailties of the human psyche and soul. This internal conflict often will eat away at the ability to achieve happiness. However, if a person lives a life that is ethical, a great deal of conflict and stress will be removed from a person’s life. This, in turn, will allow the person a semblance of happiness or, at the very least, a lessoning of conflicting tensions that prey on the mind. Prescribing to a balance of ethics and happiness hinge on the need for virtuous actions and, while this is not possible all the time, it is possible a great deal of the time and can be achieved if an individual concentrates on it enough. This is a core tenant of Aristotle’s principles of ethics, ethical behavior and virtue.

Eating Disorders Essay

Eating disorders are devastating and harmful behavioral patterns that occur within people for numerous reasons. The three types of eating disorders I will be discussing include the three most common of the disorders: anorexia, bulimia, and compulsive overeating (known as binge eating). Though the disorders take physical damage on the body, they are not in fact physical illnesses. You cannot â€Å"catch† and eating disorder. Rather, they are mental issues that develop more frequently within females but do affect the male population somewhat as well. Eating disorders are very common in our culture many people have them or know someone who does. With our cultures unrealistic views on what is beautiful the supper skinny models that woman see everywhere makes many people think that they have to live up to those standards. Some people feel if they cannot be up to these standards that they are not good enough and this causes them to do things that a person in their normal state of mi nd would never do. When people starve themselves to like in anorexia they end up developing many different psychological problems and find excuses to keep up with their destructive habits. There are also people who are addicted to eating they use eating as a way to feel a void that they feel like they have. They lean to use eating as a cooping tool in turn they become obese then they use eating to deal with their depression which works as a double edged sword. What they love is what is destroying them physically as well as mentally. This can also be considered emotional eating this is eating when you’re angry, sad, or even anxious. Many cultures have different views as what is considered attractive these variables play a large part in what peoples diet habits are this can be seen in the magazines and television from the area to show what they culture is  expecting people to look like and what they are expected to eat. Women have been the main ones with eating disorders but men with them are on the rise this is due to the unrealistic thoughts on them as well. Men are more prone to work out more than what is really necessary that way they get lower body fat. Many men think the lower their body fat the better they are this can cause many other mental issues that were not originally perceived as a female problem. With the current changes in culture the rise in men having eating disorders will keep rising. Bulimia occurs with or without anorexia symptoms. Individuals with bulimia tend to binge eat then self induce vomiting. However, binge eating is sometimes not a component of bulimia. Individuals may eat normal a mounts, and then excuse themselves to the bathroom. Another common trait is the use of laxatives, diuretics, and enemas in thoughts that it will excrete those calories. Bulimics are not necessarily underweight. Some are even over weight if not at a normal weight, and they almost always have a swollen appearance to their stomachs. Compulsive overeating is a disorder in which individuals overeat, often using food as an addictive substance. As others may turn to alcohol, drugs, or gambling to alleviate stress, compulsive overeaters turn to food. Eating disorders can plague women, and men of any age. With treatment people can overcome eating disorders and regain a normal lifestyle. They of course will always struggle with their initial issues related to food, however the treatments can teach them and give them the strength to overcome the impulses.

Environmental effects of oil pollution Essay Example | Topics and Well Written Essays - 2500 words

Environmental effects of oil pollution - Essay Example The coastal vegetations, tidal forest, and marine ecology are worse hit. It is widely known that oil spills are causing wide-ranging destruction to wild animals and marine life. Hence considerable preparation and rigid laws are required to conquer this huge problem. Attempts are being made to predict the oil spills and their devastating effects, which can curb the menace of oil pollution to some extent. Still, the international community is required to remain more alert and agile. Apparently, the best approach to deal with the detrimental impact of oil spills to the environment is to significantly lessen oil spills. To effectively minimize oil spillage demands appropriate training and effectual planning. Environmental Effects of Oil Pollution Introduction Combustion of fossil fuels is a major problem in the context of today’s environment. This major threat to the environmental sustainability is indeed an indirect result of oil pollution. Oil pollution has direct effects too. T here are numerous sources of oil pollution. Oil pollution can pollute the oceans, seas, soil, and underground water streams. Moreover, combustion of petroleum, gasoline, and diesel causes large scale air pollution. The pollutants in the air again settle into the water bodies and soil with the lapse of time by means of convection, condensation, and rain. Oil pollution due to the oil spills caused by the accidents of oil tankers and rigs is another major threat to the environment. Since the conveyance of crude oil and petroleum is mainly conducted through the waterways, accidents of oil tankers cause huge amounts of oil to get mixed in the waters of the seas and oceans (Fleming 2010). This is the main feature of oil pollution – even through pollution in the soil; the petroleum agents ultimately reach the underground water streams. In the case of the oil spills, varieties of the sea birds and animals are immensely affected. Oil pollution adversely affects the marine ecology, cau sing death to thousands of organisms (Baker 1978). It damages the natural treasures like coral reef and harms the aquatic animals like fishes, plankton, reptiles, etc. Humans can be seriously affected by taking polluted sea food. Moreover, pollution caused by the combustion of petroleum is also highly injurious to human health. In this relation, it can be further mentioned that the economic dimensions of losses due to major oil spills are considerably high (Pezeshki et al. 2000). The economic losses hamper both the industries and the financial expenditure in the various environmental reconstruction processes. Sometimes, the estimation of these losses is rather difficult. In a nutshell, effects of oil pollution are multifaceted and need to be discussed in detail. Literature Review Large scale of oil pollution particularly due to the oil spills and tanker accidents damages the oceans and seas considerably. Not only that, the petroleum agents would reach the shores and harm the coastal ecology as well. Hundreds and thousands of aquatic animals, sea birds, and plants are adversely affected. This effect of oil pollution is discernable in the US Gulf coast (Pezeshki et al. 2000). Oil spills have taken place in this region, so the effects of oil spills and clean up have manifested as environmental hazard in this part of the world. Hence, plant response to

The War in Vietnam Essay Example | Topics and Well Written Essays - 1250 words

The War in Vietnam - Essay Example The basis of such view are what elicited heated debate and controversy over the motive and gain of the US government in engaging in Vietnam War. In this regard by not understand the lopsidedness of commitment between the Vietnamese communists and the United States, the anti- Vietnam War activists claim that this paved the way for causing the most egregious blunder a nation going to any war can make.. Those that opposed the war then felt that it was obviously unnecessary, immoral or illegitimate, and there was a consensus on the nature of the war. During the initial years of the War, there was an intense dispute within civilian and military decision-making institutions mutually over the fact that the conflict was predominantly a conventional cross-border aggression or an internal insurgency. Regrettably, U.S. foreign policy advisers in the 1960s did a supreme action of miscalculation by getting involved directly in the Vietnam conflict yet the intervention proved calamitous and dreadful. There is a general consensus among the public particularly the section opposing the war that the war violated a set strategic injunction for committing military of the U.S. to a large-scale land conflict on the Asian mainland. The question thus was the war justified and was it worth such expenditure and risking the lives of the young soldiers? More seriously, in analyzing the argument was the fac t that the Vietnam War achieved very little yet a lot had been pumped in terms of cost. Anti-War theorists argued that the United States should not have invaded Vietnam since Vietnam’s political battles and internal conflicts did not directly impact or influence America. Despite the fact that U.S. politicians and leaders and military experts in one spirit agreed that Communism had at that time infringed on political freedoms and violated democracy, the war in Vietnam presented no direct threat to the government of United States or to

Econometrics Assignment Example | Topics and Well Written Essays - 1250 words

Econometrics - Assignment Example Frequently Box and Jenkin’s is an iterative method and there may be competing candidates to describe a series. To achieve stationarity or remove trend two techniques are usually applied. The first one involves fitting either a parametric model or a spline function. In this case the ARMA model is applied to the residuals. Alternatively, Box and Jenkins recommended taking suitable differences of the process to achieve stationarity. Here the assumption is that the original series is ARIMA and the difference gives rise to the ARMA series. To determine whether the series has been reduced to a stationary series, one may look at the autocorrelations. For a stationary series, the autocorrelation sequence would converge to 0 quickly as lag increases. The time plot given in Figure 2 is already a stationary series as there is no evidence of any trend. Both autocorrelation plot and partial autocorrelation plot need to be looked at simultaneously. The partial autocorrelation become 0 at lag p+1 or greater when the process is AR(p). Strictly speaking the largest PAC is at lag 2 and the second largest at lag 24. These are the only two significant partial autocorrelations. When consider the ACF at lag 24, no significance is noted. However at lag 16 ACF is significant, but no corresponding significance is noted in PACF. The two components of the observation vector y, the predicted part X ÃŽ ²-hat, and the residual y - X ÃŽ ²-hat are orthogonal. They are uncorrelated and since they follow multivariate normal distribution, they are also independent. Any function of the predicted random vector and any function of the residual vector will also be independently distributed. Using (9) and (12) given in Lecture 5 and using the result that ratio of two independent chi-square variables divided by their respective degrees of freedom, follows an F distribution with proper d.f. the F-statistic for testing parameter of linear regression
