What Is The Difference Between Diffusion and Effusion

When a volume of gas is released from one smaller area to another larger area with less pressure, the gas either diffuses or effuses into the container. The primary difference between diffusion and effusion is the barrier, which filters the gas as it moves between the two volumes. The Barrier Is Key Effusion occurs when a barrier with one or many small holes prevents gas from expanding into the new volume unless a gas molecule happens to travel through the hole. The term small refers to holes with diameters less than the mean free path of the gas molecules. Mean free path is the average distance traveled by an individual gas molecule before it collides with another gas molecule. Diffusion occurs when holes in a barrier are larger than the mean free path of a gas. If no barrier exists, consider a barrier with one large hole big enough to cover the boundary between the two volumes. Handy reminder: small holes   effusion, big holes diffusion Which Is Faster? Effusion typically transports particles more quickly because they dont have to move around other particles to reach their destination. Essentially, negative pressure causes quick movement.   Lacking the same level of negative pressure, the rate at which diffusion occurs is limited by the size and kinetic energy of the other particles in the solution, in addition to the concentration gradient.

Meat Industry Reforms in Australia

Question: Discuss about theMeat Industry Reforms in Australia. Answer: Introduction The meat and livestock industry in Australia has been identified as one of the largest industries in the country contributing towards trade and employment. In the recent years, the competition of the firms operating in the industry is largely increasing due to the market structure, pricing strategy, and labour relations. In the Australian domestic market as well as export market, the beef industry has created its mark. Meanwhile, the competitive domestic meat industry structure needs quality reforms directed to increase long-term transparency in setting prices (Long, 2016). The study paper has been prepared to investigate the current status of the Australian meat industry. Furthermore, the study of the meat industry will indicate the specific reforms that have been done in the beef industry to maintain transparency. Over the past couple of decade or so, the fundamental structure of the Australian meat industry was modified by the government to make life easier for the suppliers, meat producers, as well as wholesale marketers. The regulatory and governing body of the Australian meat industry has set up significant reform calls so that small and medium abattoirs and meat processing firms will be benefited in a substantial order. In the next section, the overall position of the industry and the reform calls directed towards the industry has been described in detail. In the Australian meat industry, the increasing market share of the supermarkets has created significant pricing issues. As a result of the scenario, pricing reforms have become mandatory to support the small and medium meat producers as well as suppliers. In the competitive market scenario, the beef marketers have demanded Senate Inquiry to set transparency in the beef market as far as price monitoring is concerned (Long, 2016). Currently, the majority of the beef producers are directly selling the cattle to meat producing firms and abattoirs. Hence, pricing transparency will be the key to the survival of the meat producers. Moreover, around twenty percent of the cattle have been settled by saleyards. Therefore, most of the meat producers are demanding to monitor market prices so that accurate rate can be given to the sellers. The Australian meat industry is worth $15.8 billion. As a result of the massive valuation of the industry, export and trade of the Australian beef industry can be identified as one of the leading businesses around the world (Sun, Hyland and Bosch, 2014). In the meat industry reforms, the Australian government has set reform policy to increase the productivity, market services and position of the meat producers. Government policies and funding have largely supported the formulised structure of the Australian meat industry (Troy and Kerry, 2010). The vigilant and robust policies directed towards the meat industry have contributed to the environmental sustainability, responsible meat production, and health-conscious food practices. The pricing policy of red meat products includes significant retail as well as wholesale prices to support the structure of the industry. In the export section, consistent strategic policies have been intervened to promote beef farming (Kidane, 2007). Admittedly, latest technologies have been included in the meat producing and processing industry to increase the productivity as well. In order to establish a monetary balance in the meat industry, the government of Australia needs a price flooring policy that will help to eliminate the issues of price fluctuation in the market (Hunter, 2013). In other words, the government needs to introduce a minimum and maximum level of price that can be charged by each level of businesses in the meat industry to eliminate the issues of unequal price. By considering the report of Long (2016), it can be seen that the different prices charged by the large sellers due to the problems of middleman has created a great buss in the market (Long, 2016). Henc e, the government needs to promote the large supermarkets like Coles and others to support the farmers and buy products directly from them in order to minimise the level of price rise in the industry. Furthermore, the government can introduce technological reforms by providing technical support and easy loans to the small and medium scale farmers. The technological reforms will help to increase the production rate of the small farmers and minimise their production costs (Laufer, 2006). On the other hand, a bulk production can be helpful in controlling the expenses and reducing the high amount of price charged by the meat producers. In order to enable the small and medium scale producers to implement technological changes, the government can collaborate with banks to provide low interest loans (de Frutos and Manzano, 2014). On the other hand, the educational support provided by the large sellers such as supermarkets and meat processing organisations can lead to an economic reform in the industry (Long, 2016). The government can support the initiative of sustainable development of the meat industry by taking the help of the large firms and supporting them to educate the small and me dium scale farmers to develop their production and sell the products at right place in right time. It is important to note that the government of Australia played an essential role during the time of BSE or better known as Mad Cow Disease. During the period of 1990 to 2006, the government provided all sorts of medical supports to the small and medium scale farmers to safeguard their cattle and livestock (Lin, Ma and Chen, 2008). Different reforms were conducted by the Australian government to minimise the import of foreign livestock to keep the Australian production safe. Hence, the Australian Meat Industry Council needs to take care of such issues in order to safeguard the industry from any sort of economic losses (de Frutos and Manzano, 2014). By considering the above analysis, it can be seen that the Australian government has supported the growth of meat industry through different economic reforms. Meanwhile, the government needs to make several new policy changes in order to mitigate the issues of price fluctuation and price discrimination in the industry. Furthermore, the government needs to implement technological reforms in the form of monetary support and educational support to increase the level of production and eliminate the crisis of meat in the market. Additionally, the government can support the small and medium scale producers to directly sell the products to large supermarkets to minimise the influence of middleman.

Nuclear Weapons Other Options Essays - Homelessness, Housing

Nuclear Weapons: Other Options Nuclear weapons, is one of today's most talked about issue. The United States alone has enough missiles to destroy Earth a few times over. Americans, then should not waste their money on taxes for building more weapons! There are other issues America must be concerned with. Why not stop the building of weapons and use the money for other needed causes? Today, over forty percent of America's national budget is used for our already large nuclear arsenal, but less than one percent is allocated for the homeless and other vital causes. For example, the money could be used for helping the homeless, working towards a drug-free America, and easing the trade deficit. The money could be put to use to ease housing costs, making houses affordable for homeless people. More houses could be built and old ones renovated or replaced. Old boarded-up buildings could be torn down and new apartments would take its place. Empty lots can be transformed in to affordable and clean rooms. Thus, more houses lowers the costs to buy one which, in turn, allows more people to move in off the streets. If home cannot be built, existing shelters could use food and medical aid. Shelters for the homeless are in bad shape and need the extra money to clean up the area. Many people talk about a drug-free America, including Georg Bush. Although he wants drug trafficking to stop, he does not allocate enough funds to accomplish the task. When production of useless weapons are stopped, the new income can be use to further the police force. More police stations, officers, and detectives are needed now. Many investigations at this moment are slowed because of the lack of manpower. Many people do not feel safe in their homes because the local police force is understaffed. All of this would change if we stop the cold war. People could walk on the streets at night, drug lords would be behind bars, and drugs would be eradicated from the country if nuclear weapons are stopped. The money would be used to set up addiction centers where many addicts can stop their use of drugs. More patrols could be set up along the border, stopping drugs before the enter this country which, in turn, would keep them off the streets and away from America's youth. Likewise, the trade deficit needs money to reverse its downward climb. Other countries are buying up American companies, and literally America itself. We owe countries billions of dollars which we can never pay off at the rate we are going. The American dollar is falling below other countries' currency. Our country needs extra money to pay debts and to renew trust with other countries. Once trust is renewed, we can again emerge as a leading super power. Hence, weapons now are gathering dust in bunkers waiting for a war that will never come. Money must be put to use for the homeless, to end the drug problem, and to lessen trade deficit. We, as a country, should worry about our problems besides the war. Let's make America that clean, drug-free place that has kept Americans dreaming for many years.

Significance of U.S. Science the 1870s essays

Significance of U.S. Science the 1870s essays Science in the United States prior to the Civil War was straggling to rise more than a few feet off the ground. Lacking positive support and participation, the few scientific organizations that were established failed to conform to newer thinking styles. With new scientific leaders, holding powerful positions and the Civil War now over, science in the United States grew vastly. A new epoch in science had arrived. Prior to the Civil War, the National Academy of Sciences hung from a precarious cliff with failing membership and lack of governmental interest. When Joseph Henry took over the presidency in 1867, his goal was to bring back the academy and reinvent it into a useful institution. First, Joseph Henry worked to get rid of Benjamin Siliman. Siliman was a key figure in the scientific of revolution in the early 1800s but was known to be a pursuer of profit in regards to science. Many believed he was a shame to modern science, and while his disbarment was not successful, the issue of membership requirements came under scrutiny. With the backing of Congress, Henry was able to lift the limits on membership and recruit younger, fresher members. By removing the limit of members, Henry was able to balance out the different fields. Henry was able to recreate the National Academy of Science into an institution that was able to create standards, promote basic research in all fields of science, and becomes advocates of science to the public. The Smithsonian was another institute that branch in the tree of U.S. science that received a facelift after the Civil War. The Smithsonian was owned jointly between the government and privately. The Smithsonian was supposed to be a support for scientists without strings, and yet that could not be realized without some sort of governmental dependence. With the building of Spencer Bairds National Museum, the Smithsonians funds were being drained at an enormous rate. Spencer tried to...

Sentiment in financial markets Essay Example | Topics and Well Written Essays - 1750 words

Sentiment in financial markets - Essay Example But if you have no feel for what the expectational environment is, you're kind of flying blind. You might have a good feel for the fundamentals and the technicals, but very often it's the expectational backdrop that makes the difference. For example, many investors are frustrated because they own a stock and the stock's earnings meet or perhaps even exceed expectations. And lo and behold, the stock goes down and people are at a loss to explain why. But for other stocks, the earnings come in and exceed expectations, and the stock skyrockets. Why the difference The reason is sentiment. Very often, the sentiment had been excessively bullish before the positive earnings report. In the days before the announcement, there may have been a heavy accumulation of call options. So there is a lot of anticipatory buying of the stock, which then pretty much has run its course when the earnings come out. But with these and other measures, you must wait until they get to some kind of extreme level before they carry contrary implications. For example, when everybody who could potentially be bullish is already bullish, then essentially most of the buying power in that particular market has been dissipated. At that point, the market becomes very vulnerable to selling because there isn't enough buying to offset the selling. Similarly, if only a very, very smal... Perhaps they have even shorted the market. That means the market has become more primed to move upward because if buyers should come in they will not encounter much selling pressure because the selling has already occurred. So imagine a poll today that says 80 percent of futures traders are bullish. Remember that people, whether futures traders or individual investors or market-letter writers, tend to be trend followers. Their opinion tends to be a reflection of what's going on in the market. So if 80 percent are bullish that doesn't mean that the market is at its peak. No. 1, you would expect them to be bullish, and, No. 2, they can always get more bullish. I think this points out a trap that the bears have fallen into. They've noticed signs of bullishness, namely the amount of money that's flowing into mutual funds, the investment clubs, the Beardstown Ladies' books and so on. You get into trouble when a market is in a powerful technical trend and you analyze it without reference to the fact that you expect people to be bullish in a bull market. When a stock rises on positive earnings, which also occurs often, there may have been a lot of concern about the earnings report and investors may have bought a lot of put options, or shorted the stock. Without a measure of sentiment that is accurate, you can go down all kinds of blind alleys. Some of those who have been bearish on the stock market will tell you that there are many more investment clubs than there were 15 years ago, or that mutual funds now outnumber the stocks on the Big Board. These are all good cocktail-party things to talk about, but they're not really measures of sentiment that have parameters associated with them. They're just anecdotal. Academic

The lack of IT systems within the logistics department of TATCO Yemen Literature review

The lack of IT systems within the logistics department of TATCO Yemen - Literature review Example Tatco-Yemen is a branch of Abudawood Group,a diversified group of companies that operates in the Middle East,Europe and the United States.The company specializes in the professional management of assets in different sectors including trading,sales and delivery of commodities,real estate,education and training of staffs,and financial investment. The company’s logistics focuses on supplying various products to consumers, an area where it has registered significant successes in the recent past. However, due to the rapid growth and expansion of its consumer base, stark challenges in the company’s management of inventory continue to exist. Tatco grapples with multiple problems related with the lack of Information Technology systems within the logistics department; these include, delays in the arrival of hard copies of important documents like invoices, causing unnecessary delays in customs clearance. Moreover, cargoes remain in the Yemeni port for longer due to lack of stora ge; and wrong information about the date of product. These problems have proved to be costly to the company. The paper explores the challenges of lack of IT systems in Tatco’s logistics department. Generally, logistics is an all-encompassing aspect of business involving planning, controlling and organizing the movement of goods and services, communications, real-time facts and people from the one point to another (Slater, 2012). Most of successful companies such as Tatco have in place strong a logistical department that supports the movement of its various assets across the country. The main problem with Tatco, however, is that most of its logistics processes are not properly integrated and built around IT systems. Processes such as handling of the materials, storage, information, shipment, packaging and inventory still lag behind, with the old paper work methods still in place (Safadi, 2003). The company suffers from ineffective logistical support and as such geographical restructuring of unfinished products, and the cleared inventories have been largely unpredictable, leading to products delays and rising operational costs (Von Der Gracht, 2008). Farooquie and Nasir (2010) in dicated that in any organization, the logistics department is expected to deliver on everything related with logistics by ensuring that the processes are developed in line with the organizational objectives of cost reduction and maximization of efficiency. However, the lack of IT systems within the organization present grave challenges to the organization’s storage processes distribution of wares, warehousing, and transportation of goods (Raj, 2009).

Accountability of the UN Peace Support Operations Essay Example for Free

Accountability of the UN Peace Support Operations Essay Global peace and security are among the United Nations core missions (Charter of the UN; chap. 1, art. 1). At its founding in 1945, the UN aimed to serve as a global high command to keep the peace in a post-colonial, post-fascist world. The end of the Cold War has made the United Nations an ever more important partner and player in the varied tasks of conflict resolution and conflict avoidance. With the closing of the ideological gap between East and West many look to the peacekeeping apparatus of the United Nations as the best tool to deal with the lesser crises that emerged after the collapse of the Soviet Union (Morrison Blair 243). Thus, there is a belief that the United Nations has a pre-eminent role to play in global peace and security (Falk 627) by means of undertaking measures that fall under the category of preventive diplomacy – peace-keeping, peace-making and peace building (Inoguchi 3). At the same time there are many critics of the way the UN has managed its security roles in the post-Cold War period. See more:Â  Masters of Satire: John Dryden and Jonathan Swift Essay Some see threatening trends in the strengthening of the powers of the UN Security Council since the Gulf War; most agree that the Security Council has limits to its effectiveness as a global policeman. Both advocates and critics of the UN peacekeeping policies recognise that to be successful the peace support operations have to be sufficiently accountable – the same way as any use of military forces in democratic nations (Newman 16). The purpose of this study is to explore what channels of accountability of peace support operations under the auspices of the UN exist and how sufficient they are. Toward this end we will scrutinize how accountability is established, who is accountable for a mandate that cannot be carried out because of insufficient personnel, examine the degree of transparency in establishing responsibility of the parties involved, discuss the cases of peacekeepers’ misconduct, and make the conclusion. The Channels of Accountability of Peace Support Operations Such conceptions as preventive diplomacy, preventive deployment, humanitarian assistance, peacekeeping and peace-building make the essence of common vision on global peace missions. This has called forth an international partnership comprising the military, civilian police, governments and NGOs, diplomatic services, mass communication media, and other establishments supporting democratisation and advancement processes (Newman 8). At present time decisions on the uses of military forces for peacekeeping operations can be taken in international establishments far from legislative authorities that democratic administrations relied on to ensure accountability. Sometimes the principles of decision-making in such supranational institutions run counter to democratic foundations (Ku Jacobson 24). In the case of peace support operations carried out under the auspices of the UN the issue of accountability especially bring up when they deal with plenary powers and amenability for decisions on deploying military forces, incurring certain risks, choosing mission goals, and carry mandates into effect (Morrison Blair 254). Here it is of great importance to realise in what ways national governments may share responsibility with the UN and at the same time retain sufficient degree of accountability to their citizenry. The scholars define such channels of accountability as: international authorisation [and] [ ] national authorisation to use military forces, democratic civilian control of military personnel and operations, civilian responsibility to the military for the safety of deployed personnel, [and] responsibility to comply with norms governing the conduct of military and other international personnel in the field (Ku Jacobson 22). Among them the first one has been implemented successfully, for the most part, due to major shift in international politics from nations operating on their own to nations which act under the auspices of international establishments. The other channels were covered by national authorities by means of legal systems and appropriate domestic procedures inculcated in national constitutions, laws, legislative instruments and regulations as well as political and military traditions (Chesterman 99). At the national level legislative and executive authorities take decisions on the goals and targets of military missions, define the rules of conduct and involvement. Officials in charge of such decisions incur a full liability for adequacy of their deeds and are accountable to the citizens who elected them (Falk 634). But in case of peacekeeping operations under the auspices of the UN the issue of accountability is more complicated. It seems unrealisable to set responsibility at the international level in the same way. Hague and Geneva Conventions which are considered as the principal international laws of war provide precise directions on the conduct of military staff in the course of their peacekeeping missions and their responsibility toward the civilians and property in their zone of operations (Boulden 9). Hence, to evaluate the sufficiency of accountability of the UN peace support operations we have to discuss how these norms apply to peacekeeping troops deployed under the UN auspices and whether such norms are observed in practice.

Abraham Lincoln :: essays research papers

Abraham Lincoln On the stormy morning of Sunday, February 12, Nancy Hanks Lincoln, wife of Thomas, gave birth to a boy. He was born on a bed of poles covered with corn husks. The baby was named Abraham after his grandfather. In 1811 the Lincolns moved to a farm on Knob Creek which was also near Hodgenville. In 1811 or 1812, Abraham's younger brother, Thomas, died in infancy. Abraham spent a short amount of time in a log schoolhouse. He began to learn his ABC's from a teacher named Zachariah Riney. He attended school with his sister, Sarah. Late in 1816 the Lincoln family moved to southern Indiana and settled near present day Gentryville. A cabin was constructed near Little Pigeon Creek. It measured 16 X 18 feet, and it had one window. Abraham's mother, Nancy, passed away on October 5th, 1818, she died of milk sickness. In 1819, Abraham would barrow books from his neighbors to read. In 1821 Abraham attended school taught by James Swaney for about 4 months. Also in 1824 Abraham attended school taught by Azel Dorsey. In 1827 Abraham's sister, Sarah died giving birth to her son. In 1831, Lincoln decided to leave his family and go off on his own. In July he moved to New Salem, Illinois, where he boarded at Rutledge's tavern and became acquainted with the owner's daughter, Ann. New Salem was a frontier village consisting of one long street on a bluff over the Sangamon River. On August 6th, 1832 Lincoln was defeated while running for the Illinois State Legislature. Lincoln began to operate a general store in New Salem along with William F. Berry. Again, In 1834, Lincoln ran for the Illinois State Legislature, but this time he was elected. During the summer, John T. Stuart advised Lincoln to study law. On December 1 he took his seat in state government in Vandalia. In 1837 Lincoln, 28, was admitted to the Illinois Bar on March 1, and he moved to Springfield on April 15. He became a law partner of John Stuart and lived with Joshua Speed. Lincoln now had income from a law practice as well as a state legislator. November 4,1842 Lincoln married Mary Todd. The first son of the Lincolns, Robert Todd, was born August 1, 1843 at the Globe Tavern. In 1844 Abraham and Mary purchased a home from Dr. Dresser in Springfield for $1500. It was located at the corner of Eighth and Jackson. The family moved in on May 2nd. In 1849 Lincoln failed in his attempt to be appointed commissioner of the General Land Office, and he returned to a full time law practice in Springfield as his

Ls311 Unit 4

Kaplan University LS311 Lori Kieffer-Garrison Unit 4 Case Study Kayla Fulrath November 19th, 2012 In this case study, we are looking into what constitutes a contract and when a person is obligated to honor a contract. In this scenario Carrie offered to sell a set of legal encyclopedias to Antonio for $300. 00. Antonio said that he would think about her offer and let her know his decision the next day. Norvel, who had overheard the conversation between Carrie and Antonio, said to Carrie, â€Å"I accept your offer,† and Carrie gave Norvel the books.The next day, Antonio, who had no idea that Carrie had already sold the books to Norvel, told Carrie that he accepted her offer. We need to determine whether or not Carrie is obligated to sell her encyclopedias to Norvel and whether or not she is breaching a contract with Antonio. The answer is yes, Carrie is obligated to sell her encyclopedia set to Norvel, and no, she did not breach a contract with Antonio. For a contract to be cons idered a contract there are certain basic elements that must be present. First there must be an agreement to form a contract which consists of an offer and an acceptance of that offer.Second, there must be consideration, which consists of a valuable exchange to support the acceptance of an offer. Third, a contract must of contractual capacity, meaning the parties involved must be competent. Lastly, the contract must be legal (Miller and Jentz, 2008). I’m going to assume that all parties are of sound mind and that Carrie is not illegally selling her set of encyclopedias because I don’t have evidence to the contrary. In the situation with Norvel, I would say a valid contract is established. Carrie has offered a set of encyclopedias for sale.Her first buyer, Antonio, does not initially accept her offer. Norvel pops up and states that he would accept her offer. So now an agreement is formed, which is part of the elements of a contract being a contract. Consideration is als o established because Norvel has paid Carrie for her encyclopedias. Here an exchange of value has taken place, solidifying the agreement. Assuming the sale is legal and Carrie and Norvell aren’t crazy, we have ourselves a valid contract, thus Carrie is obligated to sell her encyclopedias to him. In the situation with Antonio, it looks like the making of a contract.Carrie presents an offer to sell Antonio her encyclopedias. Antonio does not initially accept her offer; he basically says he will think about accepting her offer. So the first element of contract has partially been made. An offer is presented, but there is no acceptance. Had Antonio established consideration for the offer, like possibly offering a deposit for her to hold the encyclopedias and promise not to sell them before he has had time to think about it, then there would be a breach of contract. Antonio, plain and simple, did not accept the contract and did not offer any consideration for the offer.There is no breach of contract because no contract ever existed. Although there is no legal obligation for Carrie to sell her encyclopedias to Antonio, I would say there is a moral one. I think in this situation, it would have been morally correct for Carrie to contact Antonio and let him know she had another interested buyer and he needed to make a decision at that time, not the next day. He should have the first option to buy the books since he was offered them first, from a moral standpoint. References Miller, L. Roger. , & Jentz, A. Gaylord (2008). Fundamentals of Business Law.

Psychology and Health Issues

Psychology and Health Issues: Stress By: Kimberley Messina HCA/250 Have you ever heard of the term â€Å"fight-or-flight† stress response? You will feel this when you have more to worry about and handle then you are used to, or simply, when you are stressed. When your body is going through the fight-or-flight stress response, your body will make more hormones that will speed up your heart rate, give you a burst of energy, and make you breathe faster than normal (Healthwise, 2009). There are times when a little bit of stress could be useful, such as if you need to react quickly or if you need to work harder on something.For example, If you are trying to win a race or finish any work that is important on time. When you have stress that lasts for a long time or if you have stress too often, then your body will most likely have a bad effect from stress. When you are overly stressed, you can experience headaches, back pain, sleeping issues, and an upset stomach. Furthermore, stress can lower your immune system which will make it harder for your body to fight off the disease. With people who have existing medical problems, stress can make your problem worse. Stress has been known to make a person moody, depressed, and tense.This has caused many people to not do as well with their school or job, as well as having their personal relationships suffer. The mind and the body are connected, which means that stress will impact a person’s psychological health just as much as their physical health. Stress can impair your thought process, mental exhaustion, and can cause depression, psychoses, and some neuroses. You will feel pressured, overwhelmed, anxiety, irritability, nervousness, insecurity, and can have panic attacks, social withdrawal, and migraines (Healthwise, 2009).When your psychological health becomes affected by stress, it can affect anything that you are doing, such as your job, parenting, and school work. As we mentioned earlier, stress can be bene ficial if it is a small amount, this goes for your psychological health as well. It can have a positive affect on your motivation, reaction to your environment, and your adaptation. There are many psychology education programs that can help you identify your major stressors and help you manage any stress.One in particularly is called the Worksite Wellness Program, which is a site that was provided from my workplace. This website provides information on how to set up different activities and offers some guidelines on how to create some supportive policies and environments that revolve around stress management (). Within the website you can answer stress management questionnaires that can help employees assess their personal listening skills and their ability to handle stress. They also have handout notes that explain the workplace demands of the employees.Furthermore, there is an evaluation you can take within the website that will allow you to identify whether or not your worksite i s ergonomically suitable so that you can reduce any risks for repetitive motion strains. Finally, the website my job offers has handouts that you can print that will help the employees learn how to manage their stress at home and within the workplace. There are many psychological health issues when it comes to stress, as I have mentioned above. The major psychological health issue with stress would have to be its ability to mentally impair you.What I mean by this is that when you are under an unhealthy amount of stress, it will negatively affect the way you think and act. Our lives are made up of many decisions that we must make, and when under this amount of stress, it can become difficult to think clearly and make the better choice. This is because when a person is stressed, it changes the brain and causes them to have an addiction, anxiety, or depression. Stress affects many different individuals and groups and according to the American Psychological Association, the top three ca uses of stress is due to the economy, work, and money.The developmental, social-cultural, and gender factors all impact stress. Developmental traits such as any behavior towards children that is abusive can cause them to have long-term abnormalities in the hypothalamus-pituitary system, which is what regulates your stress (UMMC, 2011). Also, children face stressors throughout school, whether it is bullying, peer pressure, and tests for classes. Personality traits could also impact stress. There are people who tend to over-respond to stressful situations, which will cause them to stress more than they should.Older adults’ response system to stress becomes more difficult. The older a person becomes will impact their stress because they have to worry about higher risks for medical problems, the loss of a spouse or friends, and financial stressors (UMMC, 2011). Women, especially working mothers, will face higher stress levels because they carry a heavier load of stress than men a nd other women. They are also at risk for more medical problems due to having a child. Divorced or widowed people tend to have more stress than people who are married. They also tend to live shorter lives overall.Furthermore, people who are isolated or lonely, are targeted for sexual or racial discrimination, and experiencing a financial strain are impacted by stress much more then other people. There are a many risk factors related to stress. Some can be controlled while others cannot. You can control some situations to avoid stress such as looking for better ways to manage your time so you can get more tasks completed without feeling pressure. Also, you can try out new ways of thinking such as stopping the worry thoughts and letting go of the things you cannot change (UMMC).Taking good care of yourself such as getting enough rest and eating well can help avoid stress because you feel better throughout your day. Finally, speak up and talk about your needs and concerns because it ca n cause stress if you do not. The stressors that can not be controlled are events such as a car accident or another traumatic event, and a serious biological illness. There is no cure for stress, but there are treatment options to help you manage your stress. You can have self-care in your own home or take medical treatments.Self-care in your own home would consist of removing yourself from the stressful situation or address it, regular exercise, healthy diet and nutrition habits, meditate, acupuncture, and creating social support for yourself. Furthermore, you can also write in a journal, make a hobby for yourself, and express how you are feeling with someone you trust. It is good to laugh, cry, talk, and even express your anger in healthy ways. There are medical treatments depending on the different types of symptoms you are experiencing and how severe these symptoms are.You can receive counseling by mental health professionals and medical intervention for any of the physical prob lems that are discovered (Melissa, 11/25/12). There are a few health promotion strategies to address stress. Educating yourself is the first step in promoting good health against stress. Having the knowledge on how to handle stress when it comes your way is a good way to prepare you on how to react when it happens. When a person becomes stressed, most of the time they react in a negative way, which makes things worse.Knowing how to relax and get a grasp on the situation will help you better control your emotions and make better decisions. The next step would be to make lifestyle changes. These lifestyle changes will consist of exercise, cognitive-behavioral therapy, and using relaxation or other alternative techniques such as herbal or natural remedies (HPI, 2012). Exercise is a great stress management technique that distracts you from the stressful event and balances out the negative affect that stress takes on your body. You can do aerobics, take walks, go swimming, and take yoga, or tai chi.There are many options to choose from and all you have to do is pick one. Cognitive-behavioral therapy will help you identify the source of your stress, reconstruct your priorities, change your response to stress, and find different methods that will allow you to manage and avoid stress. Relaxation or other alternative techniques can lower your blood pressure, respiration, and pulse, and release muscle tension and emotional strain (HPI, 2012). These techniques would include going for a massage, meditating, acupuncture, listening to music, going on vacation, and hypnosis.Herbal and natural remedies such as aromatherapy and valerian can help with your anxiety and overall stress. All herbal and natural remedies should be talked with your doctor first. Throughout this paper, I have provided an overview of stress and how psychology plays a role with it. Then I reviewed a current psychology education program called the Worksite Wellness Program that was provided from my employ ment. After that, I discussed the risk factors that can be controlled as well as how to control them, and which factors that couldn’t be controlled.Next, I discussed how developmental, socio-cultural, and gender factors impact stress. Then, I talked about the treatment options that are available to the public as well as the promotion strategies to address stress. Finally, I provided information on the lifestyle changes that people will need to enhance their health and methods to prevent stress. References: Healthwise. (October 14, 2009).

Resume Writing Advice and Things to Avoid in Your Resume

Resume Writing Advice and Things to Avoid in Your Resume Resume Nightmares: Things to Never Put on Your Resume The comfortimg feeling of warm summer days may still be present in our lives, but, nonetheless, fall is already here. Still not convinced about that ï Å ? Have a look at the shop windows of the supermarkets nearby that have already started to sell their scary costumes and masks. With frolic witches and orcs, summers magic may quickly turn into a real nightmare. Even though nightmares make you wake up in the midst of night in cold sweat, they may also quickly become a reality. People sometimes consciously do things in their everyday life that can become real nightmares writing CVs, for example. Hardly anyone plans to devise a ghoulish resume; however, it frequently happens. Therefore, to introduce you to the festive mood of Halloween, we have created a list of common mistakes that make resumes look really disgusting. We have also prepared some resume writing tips to take into account when you wonder how to make a resume. The Slasher Instead of brandishing a shiny blade, an applicant will most probably provide a resume that was shortened beyond anything comprehensible and understandable. When looking at it from a distance, it may seem that the CV has all the signs promising it to be good (the format is OK, the fonts are legible, etc.), but when looking at it closer, there is nothing more apart from the lists, bullet points, and some wow words. Instead of providing a list of your benefits and strengths, consider connecting your experience and qualifications with the position you are applying for. The Psycho Hmm ... does the spelling seem rather off? Well, probably, it does. With the inception of numerous spellcheck programs, many pains regarding spelling were eradicated. However, spellchecks do not always guarantee you success. So, spend some 5-7 minutes and proofread the resume on your own or ask someone to throw an eye on it. The Blob This is a CV that is no longer a concise document that allows recruiters or HR managers to make out what qualifications or experiences the applicant has. To make it clearer, I mean that it would be proper to compare such resumes to small novellas. However, you must understand that adding more pages to your CV wont increase your hiring perspectives. Crying Wolf(man) Little lies may be fairly OK with you in your everyday life, for example, when you tell your Mom that the meat she baked is delicious although you have recently decided to be a vegetarian. However, when it comes to your CV, such lies are totally unacceptable. If you think that some small exaggeration wont spoil anything, youd be amazed how all these lies can turn against you in your future workplace when, for instance, you will be delegated an assignment that you havent a clue how to deal with. To sum up, take into careful consideration all of the aforementioned tips and you will be amazed how easier it will be to write your next resume.

Why Cow’s Milk is a Human Health Risk

Why Cow’s Milk is a Human Health Risk Except for animals under human influence and Western gulls who steal milk from lactating seals, humans are the only known species that drinks the breast milk of another species, and the only known species that continues to drink breast milk into adulthood. Don’t We Need Milk? Milk from a cow is as necessary as milk from a pig or a horse or a giraffe. Human breast milk is the perfect food for human babies, while cow’s milk is the perfect food for baby cows. Cow’s milk naturally contains the large amount of hormones and protein needed to turn a 80-pound calf into a 1,000 pound cow in one year. That amount of protein and hormones is not only unnecessary but unhealthy for humans. Because they occur naturally, these hormones are even found in organically produced milk. The Harvard School of Public Health and Harvard Medical School are downright critical of the USDAs recommendation of dairy products at every meal. Harvard states, there is little evidence that high dairy intake protects against osteoporosis but substantial evidence that high intake can be harmful. If dairy is so bad, why does the USDA recommend so much dairy? Harvard blames industry influences, stating that their recommended diet is based exclusively on the best available science and was not subjected to political and commercial pressures from food industry lobbyists. The American Dietetic Association supports a dairy-free, vegan diet: It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Besides containing saturated fats, cholesterol, hormones and too much protein, milk is also linked to testicular cancer, breast cancer, and prostate cancer. Fat, Cholesterol and Protein Many dairy products tend to be high in saturated fats and cholesterol, which have been linked to heart disease. The American Dietetic Association states: Features of a vegetarian diet that may reduce risk of chronic disease include lower intakes of saturated fat and cholesterol and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fiber, and phytochemicals. Milk protein is also a concern, and the protein in milk has been linked coronary deaths and to hardened, narrowed arteries. Hormones, and Cancer In 2006, a researcher from the Harvard School of Public Health found a strong link between dairy consumption and hormone-dependent cancers – testes, breast, and prostate. Scientist/physician Ganmaa Davaasambuu believes that the naturally occurring hormones in a pregnant cow’s milk increase the risks for these types of cancer. Milk from cows contains â€Å"considerable amounts of female sex hormones,† accounting for 60-80% of estrogens consumed by humans. Although the research focused on dairy, Ganmaa’s findings implicated a variety of animal products, as well as dairy: Butter, meat, eggs, milk, and cheese are implicated in higher rates of hormone-dependent cancers in general, she said. Breast cancer has been linked particularly to consumption of milk and cheese. Ganmaa’s findings are not unique. According to dietician George Eisman, in the US, one in six men gets prostate cancer. Only one in 200,000 men gets prostate cancer in China, where dairy is not regularly consumed. Also according to Eisman, breast cancer is highest in the countries with the highest dairy consumption. A study in England found that even within England, the counties with the highest dairy consumption had the highest rates of breast cancer. Eisman states that consuming dairy is â€Å"the most abnormal, crazy thing that we do.† Contaminants in Milk Contaminants in milk are another serious concern. American milk is banned in the European Union because of added recombinant bovine growth hormone (rBGH). When administered to cows, rBGH causes the cows to produce up to 20% more milk, but also causes the cows to produce more Insulin-like Growth Factor 1 (IGF-1). According to the Organic Consumers Association, some of the rBGH given to cows ends up in the milk. The Cancer Prevention Coalition (CPC) states: It is highly likely that IGF-1 promotes transformation of normal breast cells to breast cancers. In addition, IGF-1 maintains the malignancy of human breast cancer cells, including their invasiveness and ability to spread to distant organs. RBGH also increases the risk of mastitis, which sometimes leads to pus, bacteria and blood getting into the milk. Federal law in the US allows up to 50 million pus cells per cup of milk. If rBGH is so dangerous and is banned in the EU, why is it legal in the US? The CPC believes that, â€Å"Monsanto Co., the manufacturer of rBGH, has influenced U. S. product safety laws permitting the sale of unlabeled rBGH milk.† Another contaminant found in cow’s milk is pesticide residues. Residues are fat soluble, which means they become concentrated in the milk and tissues of animals. What About Calcium? While cow’s milk is high in calcium, it is also high in protein. Excess protein in our diets causes calcium to leach out of our bones. Dr. Kerrie Saunders states, â€Å"North America has one of the highest consumptions of dairy products, and also the highest incidence of osteoporosis.â€Å" To combat osteoporosis, Saunders recommends exercise and â€Å"beans and greens† for a source of calcium that is not excessively high in protein. Ganmaa also recommends getting calcium from green leafy vegetables. Furthermore, calcium intake may be less important for bone health than we’ve been led to believe. A study by researchers from the Harvard School of Public Health published in 1997 found that increased consumption of milk and other calcium-rich foods by adult women did not reduce the risk of osteoporotic bone fractures. Calcium retention is also important for preventing osteoporosis. Sodium, smoking, caffeine and physical inactivity can all cause us to lose calcium. While animal rights advocates are vegan for ethical reasons, it’s important to know that cow’s milk is not necessary for human health and foregoing dairy may have health benefits.

Entrepreneurial Survival Essay Example | Topics and Well Written Essays - 1000 words

Entrepreneurial Survival - Essay Example Therefore, it is important for any company to prioritize credit management and cash flow for increased profitability and survival. There are different issues involved in managing credit in a company. A company first needs to understand well the credit and payment issues of its customers before carrying on a relationship with them. It is essential for a company to identify the high risk customers in order to adopt the most effective strategy of prioritizing collections. The nature of the credit controller of a company also influences the credit management, hence it is vital that a company utilises different credit controllers. Additionally, effective credit management involves strengthening existing customer relationships. A company could for instance renegotiate credit prices with loyal customers, among other incentives, since intuition to customer needs is an important aspect of credit management that can result in more profitability (Bullivant 2012). Having a company credit policy is critical, and this must be up to date with the present creditworthiness of specific customers of the company. Credit insurance is also important in the covering of individual accounts or the whole turnover of company (Chartered Institute of Management Accountants 2009). The strategies used in credit management impact on cash flow. Therefore, effective credit management improves cash flow. However, there are additional factors that enhance the cash flow of a company. First, improving the speed at which goods exchange hands with the buyer is important, because the faster a buyer purchases and pays for a good, the better it is for the company’s cash flow, even as inventory must move for cash to flow. Improved technology for faster payment and delivery of goods also helps to move inventory. Additionally, the use of information is key in improving cash flow. For instance, when delivering goods to customers, a company must track the

Literature review of my research about Dual authority in matrix Essay

Literature review of my research about Dual authority in matrix organization - Essay Example This resulted in the creation of a structure in which a number of employees were working under two heads, the department head or the project manager of the interdisciplinary project team. When this structure was depicted in paper, it was found that the crossing of the organizational lines could be represented in the form of grids or a matrix. Henceforth it was termed as matrix organizations (Kuprenas, 2003, p.1). When it is compared with the other forms of organizational structures, it is viewed as a combination of the traditional hierarchy which is overlaid with some form of lateral authority, influence or communication. The overlay creates a combination of commands, one which is long the functional aspects of the project and another which are along the project lines. Assuming the complexities of the project management in the business world of today, matrix structures are primarily used where the requirement of technical assistance across many different areas are required (Kuprenas, 2003, p.1). This structure is especially preferred in large scale consulting, the construction and the aerospace industry. One of initial and first users of the structures was Bureau of Engineering in the City of Los Angeles. However, certain problems were faced during the implementation of the same (Kuprenas, 2003, p.1). Implementation Challenges of the Matrix structure Research shows that implementation of the matrix structure in any organizational structure is difficult. Implementation of the matrix design in the Bureau of Engineering came with a number of difficulties. The Bureau experienced a number of confusions and conflicts with regards to the responsibilities and roles of the functional manager

Modern Business Essay Example | Topics and Well Written Essays - 2250 words

Modern Business - Essay Example Research scholars have classified industrializations as ‘early’ and ‘late’ in accordance to their origin. It has been observed that, industrial progress of particular country has simultaneously influenced companies to improve organizational and business performance. The concept of competitive advantage for national business system of different countries has an underlying linkage with ‘early’ and ‘late’ industrialization process. It is evident from the above example that time period for evolution of industrialisation is different for every country and each of the country followed a distinctive pathway to bring industrialization. Chronologically, the United Kingdom was the birthplace for industrialization during nineteenth century and then followed the USA. Industrialization in other European countries took place during the twentieth century, while in countries like China and Japan; industrialization took place after the Second World War. Objective of this essay is to explain how organizational and institutional characteristics of national business systems in different countries have affected by ‘early’ and ‘late’ industrialization process. Porter diamond model for national business system of different countries and theories regarding industrialization process will be discussed in order to build theoretical background for this essay. The study will cite examples of countries and industries in order to compare national business system of different economies. In the last section, the essay will try to throw some light on issues like sustainability of national competitiveness of various countries, in order to understand effectiveness of industrialization. Theoretical Background Early Industrialization & Late Industrialization Research scholars have stated that late industrialization process in various nations is deeply influenced by resource mobilization and intergenerational concept mobil ity. Late industrialized nations have already achieved significant feet in terms of resource mobilization and national capability development. Therefore, it can be said that, economic development of late industrialized nations started late but the growth rate of these countries can surpass the growth rate of those countries where industrialization took place early. Theoretically, late industrialization took place in those countries, which were economically backward due to over dependence on agriculture and lack of industrial output during early years of twentieth century. In 1979, OECD had published a report about countries which were industrialized at later half of twentieth century. According to this report, countries like Portugal, Hong Kong, Greece, Taiwan, Mexico, Brazil, Spain and South Korea have experienced industrial growth at later half of twentieth century and these countries are called as NICs or "newly industrializing countries" (Balassa, 1981). Industry experts have st ated that economic growth in late industrialized countries is different in comparison to countries which are industrialized in early point of time. According to Balassa (1981), three factors, such as contribution of the industrial sector in labour force employment, rise in per capita income and percentage rise in

Factors Affecting Velocity of a Sphere Rolling Down Incline

Factors Affecting Velocity of a Sphere Rolling Down Incline Factors affecting the velocity of a sphere rolling down an incline. An experiment was performed investigating the factors affecting the velocity of a ball rolling down an incline. After investigating how mass, angle of incline, and center of mass affect the velocity of a ball rolling down an incline, it was determined that the hypotheses of The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach., The greater the mass of the ball, the greater velocity the ball will reach., and The more centered the mass of the ball, the greater velocity the ball will reach. were supported. Lane Dederer There are multiple factors affecting the velocity a ball gains while descending an inclined plane. One simple factor that will affect the velocity of a ball rolling down an incline is the angle of the incline. This is due to the fact that when the angle of the incline is increased, the height of the incline also increases. Gravitational potential energy equals mass multiplied by gravity multiplied by height (), meaning height is one of the factors affecting the potential energy the ball possesses. The higher the angle of the incline, the faster the velocity Another factor affecting the velocity of a ball rolling down an incline is the mass of the ball, which is also a factor in the gravitational potential energy equation. The last factor that will be discussed is mass distribution within the ball. The velocity of a ball rolling down an inclined plane could be affected by the location of mass within the ball. For example, if the majority of the mass of a ball is located on one side, this would likely create different results compared to a ball in which mass is distributed evenly. (Hyperphysics.phy-astr.gsu.edu, 2017) While potential energy is determined by the equation of , the actual energy produced (kinetic energy) is also dependent on rotational kinetic energy of the ball, which is represented by the equation . In this equation, and . Â   Â   Gravitational potential energy Gravitational potential energy or GPE is a type of potential energy possessed by an object due to its position in a gravitational field. (Hyperphysics.phy-astr.gsu.edu, 2017) One way to demonstrate this concept is a ball rolling down an incline. When the ball is stationary at the top of a slope, it possesses 100% gravitational energy, meaning none of its potential energy has been converted into another form of energy. When a ball rolls down an incline, its gravitational potential energy is converted into motion, or kinetic energy (KE) which will be discussed next. When the ball has travelled half way down the incline, it possesses 50% GPE and 50% KE. When the ball has travelled 75% of the distance down the incline, it possesses 75% KE and 25% GPE. When the ball has travelled 100% of the distance of the incline, it possesses 100% KE and 0% GPE. This is due to the fact that all of the balls GPE has been used or converted into KE. At this point the ball no longer possesses any potential to be put into motion unless acted on by an external force. Gravitational potential energy can be calculated using the following formula: Which simplified looks like the following: This equation shows that the higher the height of an incline, the more potential energy would be possessed by an object at the top of the incline. The equation also shows that the higher the mass of an object, the more GPE it will possess. While acceleration due to gravity (g) is also a variable in the equation, as the acceleration of an object due to gravity is the same everywhere on earth. (Physicsclassroom.com, 2017) Kinetic energy Kinetic energy is the energy of movement, or motion. It is defined as an object in motion possesses kinetic energy. (Hyperphysics.phy-astr.gsu.edu, 2017) Kinetic energy can be calculated using the following equation: Simplified: The equation for kinetic energy shows that it is dependent on mass and velocity. Therefore, the higher the mass of an object the more kinetic energy it possesses, and the higher the velocity of an object the more kinetic energy it possesses. (Physicsclassroom.com, 2017) Friction Friction is a form of resistance between two solid objects. The amount of resistance between these two solid objects is in most cases dependent on the force holding the surfaces of the two objects together, and the roughness of each surface. The formula for friction is as follows: Where: (Hyperphysics.phy-astr.gsu.edu, 2017), (School-for-champions.com, 2017) The hypotheses for the experiment are as follows: The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach. The greater the mass of the ball, the greater velocity the ball will reach. The more centered the mass of the ball, the greater velocity the ball will reach. Equipment was gathered including a 1 meter long flat wooden board, 4 table tennis balls, a stopwatch, fine sand, water, a drill, adhesive tape, and a stack of textbooks. Firstly, the wooden board was placed one end touching the desk and one end supported by the textbooks, creating the incline that was used for the experiment. An opening was then drilled in 3 of the 4 table tennis balls to allow for insertion of water and sand, allowing balls of varying mass. Once the incline was at the desired angle, the ball being tested was held at the top of the incline. The first participant suspending the ball at the top of the incline gave a countdown, prompting the second participant to start a stopwatch as the ball was released. As soon as the ball reached the bottom of the incline, the stopwatch was stopped. The time provided from the stopwatch was then arranged in a table. This process was repeated three times for each angle in test one (how the angle of incline affects the velocity of a ba ll rolling down an incline), and five times for each angle in test two. (how mass affects the velocity of a ball rolling down an incline) As test one was not testing any variables to do with mass, it only required one ball to be used throughout the test. The sand filled ball was chosen for this as it was solid and consistent. Angle of incline The way the angle of the incline affected the balls velocity was tested by rolling the ball down an incline at angles of 5Â °, 10Â °, 15Â °, 20Â °, 25Â °, 30Â °, 35Â °, 40Â °, and 45Â °. Each of these increments were tested three times, ensuring accurate data. The angle of the incline was calculated using trigonometry, using the height of the incline and the length of the incline (the hypotenuse) to find the required angle. Textbooks were used to support the board at the correct height. Once the correct angle of incline was met, the ball was timed rolling down the incline 3 times for the sake of accurate data. This process was repeated for every angle being tested. Mass of ball The effect the mass of the ball had on velocity was investigated by testing three balls of different masses. One ball had a hole drilled in it and was filled with water (36.2 grams), one ball had a hole drilled in it and was filled with sand (52.4 grams), and one ball was left as it is (2.7 grams). Each of these balls were timed five times rolling down an incline of 20Â °. All data from the experiment was recorded on paper and arranged in a table, so it could then be graphed, allowing the data to be analysed and observed in an organised fashion. As , the velocity the ball reached can be calculated using the time recorded from the experiment, and the distance, which is the length of the incline which was simply measured with a ruler to be 0.91 metres. An example of this for the ball rolling down the 0.91m incline in one second is as follows: Independent, dependent, and controlled variables The independent variables in this experiment include the angle of the incline, the mass of the ball, and the mass distribution of the ball. The dependent variable in this experiment is the velocity of the ball. Controlled variables are variables apart from independent and dependent variables that can still affect the results of an experiment. The controlled variables in this experiment are the surface the ball is rolling on, the material the ball is made of, the size of the ball, the measuring devices being used, the distance the ball travels, and the method being used to release the ball each time, for example the position of the hand. Safety In this experiment safety glasses were worn by participants to prevent any possible damage to the eye. The landing zone where the ball reached the bottom of the ramp was blocked with a stack of textbooks. This choice was made as the ball possessed a reasonable amount of kinetic energy as it came off the incline, meaning it could interfere with other classmates experiments and even become a hazard. (for example knocking a glass beaker off a bench) While these situations are quite unlikely it is good practice to evaluate any possible errors that could occur in an experiment and prevent them from occurring in the first place through proper safety practices. Test 1: How the angle of incline affects the velocity of a ball rolling down an incline. Angle of incline (degrees) Time taken to roll down incline (seconds) Test 1 Test 2 Test 3 Average 5 1.82 1.59 1.68 1.70 10 1.12 1.15 1.04 1.10 15 0.82 0.63 0.81 0.75 20 0.75 0.69 0.63 0.69 25 0.66 0.44 0.59 0.56 30 0.66 0.69 0.47 0.61 35 0.59 0.53 0.63 0.58 40 0.41 0.53 0.47 0.47 45 0.50 0.54 0.47 0.50 By using the equation for velocity ( simplified as ), the above timed results can be converted into velocity.

With all values substituted in, the equation for energy transformation is as follows: Which provides the velocity of the ball at the bottom of the incline: (Hyperphysics.phy-astr.gsu.edu, 2017) To find the velocity of the ball from this point, the values for g and h are simply substituted into the equation. For example, to find the theoretical velocity for a ball rolling down a ramp that is 10 centimetres high the equation will look like the following: This equation will be used to work out the theoretical velocity for each ramp height. All results can then be put input into a table or graph to observe and compare real results to theoretical results. Angle of incline (degrees) Test 1 Test 2 Test 3 Average velocity (metres per second) Theoretical velocity (metres per second) 5 0.50 0.57 0.54 0.54 1.06 10 0.81 0.79 0.88 0.83 1.50 15 1.11 1.44 1.12 1.21 1.83 20 1.21 1.32 1.44 1.32 2.08 25 1.38 2.07 1.54 1.63 2.31 30 1.38 1.32 1.94 1.49 2.51 35 1.54 1.72 1.44 1.57 2.70 40 2.22 1.72 1.94 1.94 2.85 45 1.82 1.69 1.94 1.82 2.99 The results gathered from this experiment while not following theoretical results, prove to follow projected results relatively closely in the above graph. The comparison between the two sets of data shows that both quite closely follow the same path, however the real data is just lower than the theoretical data. Some possible reasons for this difference include the fact that the equation doesnt account for friction, and the quantity of angular momentum. While the energy lost due to unaccounted for friction in the experiment would be negligible, as acceleration is an exponential value, a small change in the amount of energy in the experiment could noticeably change results quite quickly. The equation used for theoretical data also wasnt accounting for the angular momentum of the ball. Angular momentum is a is a form of stored energy observed in things such as a rolling ball. This means while the ball in the experiment was rolling down the incline, it was storing part of its energy as angular momentum, taking away from the actual kinetic energy of the ball. Both factors combined can create quite a difference in real data compared to theoretical data, which is one explanation for the difference between real and theoretical data. While the results are not perfect, in the angle to velocity graph the real data gets closer to the predicted theoretical value as the experiment goes on. The real results get proportionally closer to projected results even though looking at the real results there appear to be outlying data points bringing down the value for the average velocity of the ball in the second half of the graph. This is proven below. This proportional gap being closed more the further the experiment progresses is thought to be due to the exponential nature of acceleration. First four points of graph: Second four points of graph: By evaluating the results from test 1, it is made clear that the higher the angle of incline, the higher velocity the ball will reach. In case the increase in velocity compared to increase in incline angle is not completely uniform. However the addition of a trend line shows that while there are outlying points lower than expected, the data shows that the velocity of the ball is still increasing as the angle of the incline increases, which supports the hypothesis of The greater the angle of the incline the ball is rolling down, the greater velocity the ball will reach. The second test involves four different ping pong balls. One is a regular ball, one filled with water, one filled with sand, and one half filled with sand. The ball half filled with sand will be ignored for now. By evaluating the results from test 2, it is shown that the regular ping pong ball (2.7g) is the slowest of the 3 balls being analysed, with an average velocity of 1.18. The ball filled with water (36.2g) comes in with the next highest velocity with an average of 1.32. Lastly, the ball filled with fine sand (52.4g) reaches the highest average velocity of the three, coming in at 1.42. This data is seen displayed in the mass to velocity graph from test 2 on page 9. By analysing this graph it is made clear that the hypothesis of The greater the mass of the ball, the greater velocity the ball will reach. is supported, as the velocity is clearly seen going up as mass of the ball goes up. The last hypothesis is related to the ping pong ball that was only half filled with sand that was mentioned previously. This ball was made with the intention of analysing the effects the center of mass has on a ball. This ball came in with an average velocity of 0.96, which is by far the lowest average velocity of the four balls. By observing the mass to velocity graph from test 2 it is clearly seen that the ball half filled with sand has a significantly lower velocity than the rest of the balls tested. Therefore, the hypothesis of The more centered the mass of the ball, the greater velocity the ball will reach. Is supported. Using the square root function the results from each set of data can be compared. The equation used to calculate theoretical data can be simplified to the square root function, meaning both equations can represent the same line. This will be demonstrated below. Looking at the graphed results and placing a power trendline on each set of points shows that the above equation relates directly to the equation of the lines in the graph. This comparison is shown below. Looking at the equations for each trendline it can be deduced that they can be represented by the square root function. Throughout the experiment in this investigation there are many aspects that could lead to flawed or inaccurate data. While the data didnt exactly match theoretical data, it quite closely followed the predictable nature of a power trendline. The results that stray the most from the trendline are the results from the second half of the angle of incline test, between 30 and 45 degrees. These seemingly anomalous results are most likely due to the measurements for the experiment being recorded by humans. The times for the experiment were recorded by a participant using a stopwatch, meaning there are multiple points throughout a single run of the experiment that could lead to inaccurate results. The first is the ball being released. One participant held the ball at the top of the incline, and with a countdown would release the ball, prompting the second participant to start the stopwatch. This part of the experiment alone can create slightly inaccurate data, as the participant starting the stopwatch is reacting to the visual que of the ball being released and the audio que of a countdown. According to backyardbrains.com, the average human reaction time to a visual stimulus is 0.25 seconds, and 0.17 seconds for audio stimulus. As both of these are involve

Shakespeare’s Creativity Essay -- Literary Analysis, Twelfth Night

Shakespeare’s Creativity In William Shakespeare’s Twelfth Night, the art of music appears in the opening of the speech as the unhappy and lovesick Orsino tells his musicians, â€Å"If music be the food of love, play on† (I.i.1) In the speech that follows, Orsino asks the musicians to give him so much musical love i.e. food that will â€Å"surfeit† and cease to yearn for love any longer. Shakespeare uses music in opening line of play and at the end by Feste singing his song. It reveals that Shakespeare has presented on stage a romantic comedy which is not detached from our everyday reality. Thus songs are used by Shakespeare with surfeiting desire not only for the purpose of entertaining the audience but also closely linked to the play’s theme. Defining Music Music, as commonly in the English Oxford Dictionary is the â€Å"art or science of combining vocal or instrumental sounds to produce beauty of form, melody† or â€Å"the vocal or instrumental sound produced by practical exercise of the art of music†. Music is also described as â€Å"a musical composition or a performance† which can be seen in Shakespeare Cymbeline: â€Å"I haue assayl’d her with Muscikes, but she vouchsafes no notice† (II.ii.37). Shakespeare also uses music as the â€Å"cries of a pack of hounds on seeing the chase† (IV.i.105) in Midsummer Night’s Dream. Music in Shakespeare’s Twelfth Night opening speech is written as â€Å"MuÃ… ¿icke† in the EBBO version whereas it is spelled â€Å"music† in our class text. The word â€Å"music† has been spelled differently throughout the years. Shakespeare uses the word â€Å"music† differently in his plays, such as: â€Å"musickes,†  "musique,† and â€Å"music.† The word â€Å"music† is spelled differently in the OED and in the song, with different alphabetic but pronounced the same way.... ...are’s writings. Edward W. Naylor writes in his essay that, â€Å"this is the more satisfactory, as no subject in literature has been treated with greater scorn for accuracy, or general lack of real interest, than this of music†. Music is the only topic that the audience and the readers view with content and a smile on their face. Shakespeare’s musical references are mostly found in comedies, but the musical stage direction that is presented in tragedies is due to the military nature or politics that bound the play. Shakespeare knew the impact of music on the society and during his time. Naylor also suggests that music â€Å"was considered an essential part of a clergymen’s education† and this notifies the value music held in the society. In the Duke’s case, â€Å"If music be the food of love, play on†, music seems to be rigorous and the musicians perform it with peacefulness.

Realism vs. Surrealism

Why is he so important? What makes is death so significant? † Realism vs.. Surrealism Books are a major piece in the puzzle of life. When books, a source that points out a society's imperfections, are taken away, humanity is lost. In Ray Bradbury scientific novel Fahrenheit 451 , firemen are the people to start fires, rather than extinguish them, as they do in the modern world. They also investigate homes that are reported to be sheltering books.Owning books and reading books is against the law in this eating, and if any are found during the investigation, the owner is arrested and the books are burned. Captain Beauty, the leader of the firemen, is portrayed as a mysterious and suspicious man, who goes around quoting books during the day, and burning them at night. Later on in the story it was made clear that Captain Beauty has read books in his lifetime; however he turned away from them because he was required to think on his own.Ray Bradbury created this character to show th at the awareness of imperfections in society can, in some case, lead to the missing desire to use the knowledge. Beauty is the type of person, who after learning the truth and reality, returns to the unreality he was used to. This relates to Plat's Allegory of the Cave. The cave that Plato thought of was set up with prisoners chained up, facing a wall that projects shadows originating from puppets behind the prisoners on a platform. Beneath the platform and behind the prisoners is an opening which leads into the real world.The essence of the philosophy is that a prisoner is let go into the real world with the knowledge they have, such as the puppets' shadows. For example, if a prisoner saw a go in the real world, he would think that it is fake, because he accepted the reality of the shadow of the dog projected on the cave wall. The slave then realizes, the images shown in the cave are an unreality. Once they are exposed to the truth they cannot return to the life they once knew. The character Beauty was a representation of a prisoner or slave chained up in the cave.Beauty became free, and he started reading books and questioning society, representing the transition from the cave to the real world. The moment he was exposed to the truth, he did not enjoy it, because he had o think on his own. Beauty then returned to the life he knows is a lie. Despite the fact that Beauty returned to the cave, he read the books so intuitively that he was able to quote them and give them some significance to his life. When Montage felt sick, Beauty visited him because he knew Montage had stolen a book from the reported house they investigated the previous night. He lectured Montage on how nothing valuable comes from books.For example, during the lecture Beauty says â€Å"Well, Montage, take my word for it, I've had to read a few in my time, to know what I was about, and the books say thing! Nothing you can teach or believe† (62). By saying this to Montage, Beauty is tryin g to prevent him from â€Å"leaving the cave† or learning that humanity has many imperfections. Beauty feared that if Montage learns the truth about the society they live in, he will also be cowardly to make a difference and return to the unreality as Beauty has done. Despite the fact that Beauty returned to the false world, his ‘contaminated' mind could not forget the lessons he had learned from books.Beauty's character served a purpose to demonstrate that there is a restriction towards what en can do; however, with all the knowledge of humanity Beauty has acquired, he chooses not to do anything. Beauty served as a very significant character throughout the novel. He is a combination of Montage, someone who wanted to learn about the imperfections, and Mildred, a shallow and a cowardly person. He is similar to Montage in the sense that he read books, and questioned society. Montage, however, wanted to make a difference, so he came up with a plan. â€Å"If you thought it would be a plan worth trying, I'd have to take you word it would help† (86).Montage thought of a plan to sabotage he lives of the firemen by planting books in their houses, having them arrested, and as a result their houses would be burned. They would be left with nothing and they would be in Jail. This would give Montage and his helper, Faber, time to plant more books in other civilian homes. Beauty displayed many of the qualities that Montage possessed, despite the fact that Montage was proactive to solve problems. Beauty is similar to Mildred because he learned all this valuable information, yet he threw it away, because he did not want to burden himself with thinking about the books and hat they truly meant.When Montage shows Mildred, his wife, all of the books he has been hiding, he asks her to read them with him. As they are reading Mildred, who is too confused and frustrated, shouts â€Å"What does it mean? It doesn't mean anything! † (68). Mildred did not under stand why she had to think about the book, and Beauty returned to the cave' for the same reason. He did not want to go through the tedious process of thinking about what the books mean. Despite the frustration, when Beauty quotes the books throughout the novel, it indicates he received meeting from books; however, it was not enough for him to completely leave the cave.With Beauty being aware of the knowledge he has, but refusing to make a change, his death is instantly made significant. Before his death he quotes the famous line from the Shakespearian tragedy Julius Caesar â€Å"There is no terror, Cassias, in your threats, for I am arm's so strong in honesty that they pass me as an idle wind, which I respect not! † (119). Beauty says this to Montage, while he is pointing a flamethrower directly at Beauty, to show him that he is not scared to die. In that same vein, when Montage kills Beauty, before him is the path he must take to make a difference; however, without the obsta cle: Beauty.Montage is no longer surrounded with the constant reminder that books and independent thoughts are useless. Later on in the novel, a terrifying realization dawns over Montage; that Beauty wanted to purposefully die. He says â€Å"Beauty wanted to die,† as he comes up with an explanation for Beauty's unusual wish. Beats desire to die, was because he was not satisfied with what his life has become. He had gone through the trouble of escaping the cave, reading the kooks and trying to understand their content. Unfortunately, Beauty was unwilling to think on his own, therefore he returned to the unrealistic life.While seconds away from his death, Beauty sees an image of what he could have become if he put aside his frustration with comprehending the books ; Montage, a person who chooses to use the knowledge he has gained. Both firemen started out the same way. They both loved their Job, but one day they started questioning society which led them to reading books. Monta ge, however, wanted to make a differ Renee and learn to understand the world that was hidden away from him, while Beauty returned to the cave because it was the easier life to live.Ray Bradbury novel Fahrenheit 451 follows the framework of Plat's Allegory of the Cave, and although many characters have to partake in the Journey of leaving the cave, a single character Beauty, has a unique participation in the Journey of exiting the cave. When Beauty is introduced in the setting quoting books, his character's demeanor takes an unexpected turn. He is perceived as a tough and loyal fireman; however, no one knows that in the past, he was a law-breaker.Beauty was curious to discover the content of those mysterious books and he read many attentively, and received enough knowledge to quote them in any type of circumstance. He became too frustrated with comprehending the books which led to his willing transition from reality to unreality. Ray Bradbury created this character to show the ignora nce of humanity when one must think independently. Captain Beauty was important to the novel because he was a controversy between Mildred, a shallow prisoner, and Montage, a prisoner trying to escape. Without the combination of the two, there would to be any balance.Captain Beauty's death, allowed Montage to continue his Journey with the eradication of his main obstacle. It also was significant because it revealed to the reader that Captain Beauty was miserable living in the fake world when he had already been exposed to the true imperfections of society, and he could not live with himself that he sacrificed a chance to make a change, the way Montage has. Without books, the imperfections of society are not pointed out and many people gain the courage to understand the truth rather than accepting the reality that is presented to them.

A Day in the Life: Career Options in Library and Information Science

Pricilla Shontz has been known for her understanding of the major issues of library developments during the current systems of referencing and research that are involved in making library procedures more organized. Her idealisms of library management has actually increased the knowledge of librarians in assisting the development of book and literature arrangements that naturally suits the needs of the students and researchers at present. Her implicative suggestions in the matter actually increases the competency of the library systems in making an impact on the increased need of researchers today for referencing approach in libraries. The book of Shontz actually intends to show the matter of concern that is supposed to be understood at present with regards modern library systems including that of involving information technology within the arrangement of references readings in libraries. Obviously, this reading increases the capability of the library professionals in getting along with the modern flow of technology and referencing systems. This reading then introduces the new systems of understanding with regards library arrangements and organization that would be most suitable for the modern students and researchers of the modern society. As noted by the author herself, she described the life of the librarians today much more different than that of the lives of the librarians before (19). Likely, she wants to show how much technology changed not only their job but also their lives as major custodians of the different mediums of references and study that would be most helpful to the current generation as they face further challenges in the said field of social life. A librarian is naturally expected to spend at least 60 percent of her or his whole day inside the library trying to accurately arrange reading materials and other mediums for research that are to be used for further progress of the society. With the implication of the modern technology, however, the said 60 percent of a day-time of a librarian could now be divided into different tasks that they could complete for a whole day for the betterment not only of the references but of the whole library establishments as well. (Career Profiles, Internet) The book consisted of chapters that introduced different essays from different authors who are likely able to present the principles of library professions that Shontz herself appreciate and aim to apply. The summary of the said essays particularly want to integrate the old system of library organization with the modern systems of computing. Today, the use of OPAC (Online Public Access Catalog) is already appreciated among libraries around the world (Career Profiles, Internet). This particular innovative design for cataloging has naturally increased the accuracy of referencing in the libraries (Shontz, 19).   The referencing system likely increased the matters of accuracy among furthering studies in the different sections of understanding such as medicine and psychology as well as mathematical studies that increases the understanding of the different theories connected with furthering technology (Shontz, 21). Suddenly being electronic in the system has caused considerable insecurities to old librarians in the field, although practicing the said profession through following the said innovations in technology makes all the sense in the changes being adapted within the system (Shontz, 24). Likely, the matter of development increases the capability of library professionals in handling the needs of their clients [mainly the students and the researchers as well] in a more effective matter.   As noted from the reading, the modern process of Information Technology could be utilized to increase the competencies of the librarians in handling the needs of their clients in a more efficient time. This is primarily because of the fact that e-technology makes a more organized library that would help well in referencing and literary organizing systems. Moreover, the possible integration of the old and new systems of library handling actually gives a higher level of competency in the said system thus making the process more effective for the sake of social progress as well. It could be observed that most people are now concerned with technological systems. In terms of library professional approach, it could be noted that the application of information technology also increases the competency of the said profession. The presentation of the author with regards this truth actually makes the matter more understandable and clear for others to comprehend with and thus make use of the information for actual application within the said profession. Overall, the discussion held by the writer of this book is considerably excellent in presenting the cons and pros of the said system of library approach. Reference: Priscilla K. Shontz. (2007).
