World Trade Organisation Essay -- essays papers
World Trade Organisation The official World Trade Organisation web site, defines the WTO as ââ¬Å"the only global international organisation dealing with the rules of trade between nations . . . [through] helping producers of goods and services, exporters, and importers (to) conduct their businessâ⬠1. It was formed in 1995 after growing out of and extending the institution of the General Agreement on Tariffs and Trade. As of the thirtieth of November 2000, the WTO has 140 member-countries, over three-quarters of which are developing or least-developed countries. As the WTO implies, its current role is to serve as the lubrication for the joints in the engine of globalisation; although just how effective and fair this lubrication may be, is still a point of great contention. The WTO preaches that its purpose and effect are to ââ¬Å"improve the welfare of the people of the member countriesâ⬠2, and it claims that this is achieved by administering trade agreements, and monitoring and handling trade disputes. This essay will test the truth in this statement, of whether or not the actions taken by the WTO have failed to further enhance the welfare of the people of its member countries, and if so, whether the WTO therefore needs to be either reformed or even abolished. The criteria by which I will assess this truth, takes into account the three major arguments that are held against the WTO, with regard to its affect on the welfare of the people of its member countries. One of these arguments is that the international rules the WTO authors, consistently favour multinational corporations at the expense of workers and small farmers. Another argument is that by removing trade barriers as the WTO seeks to achieve, jobs are ââ¬Ëexportedââ¬â¢ to lower labour cost countries where the standards to which the labourers are subjected, are below what is internationally accepted. The final main argument against the WTOââ¬â¢s aims that is raised, is that if countries cannot make their industries globally competitive, they will experience a decline in their peopleââ¬â¢s standards of living. Judging the results of these arguments, will allow me to decide whether or not the WTO is in need of reform, abolishment, or if it should continue without alt eration. The basic premise of the WTO is to open up trade between nations, and one of its potential disadvantages is that its opera... ...) ââ¬Å"Slow out of the blocsâ⬠The Australian February 1 p.28.

The Relationship Between Katherine and Bianca in The Taming of the Shre
The Relationship Between Katherine and Bianca in The Taming of the Shrew à à William Shakespeare is considered the greatest playwright of all time.à His gift for developing characters is one major aspect that accounts for this lofty acknowledgement.à Shakespeare created various characters from drunks and fools to kings and generals.à The characters are so human and so real that the audience can see aspects of their own personalities represented on stage for better or worse.à Inadvertently, Shakespeare's ability to characterize any type of person demonstrates his holistic education and knowledge of everything from military strategy and open sea sailing to music and religion.à As a result of Shakespeare's true-to-life characters, the relationship between Katherine and Bianca in The Taming of the Shrew is completely realistic, reflective of every aspect of the ever-present phenomenon of sibling rivalry.à à Some people believe that sibling rivalry is nothing more than a series of petty disputes between hyperactive adolescents, a childhood trauma that most people outgrow. However, sibling rivalry also encompasses much more serious cases, like the permanent enmity between adult siblings. This phenomenon was studied extensively in the nineteenth century, when Charles Darwin presented his theory of evolution.à At that time, he said that one of the major causes of sibling rivalry is natural, and it occurs in nature when the competition is usually for food.à Specifically, whenever two individuals that consume the same type of food co-exist in the same area, they fight with each other until one of them manages to kill or drive the other out, leaving the winner with the exclusive use of the food resources a... ...es and further contributing to Shakespeare's reputation as the greatest dramatist and finest poet that the world has ever known. à Works cited: à Barton, Ann.à "The Taming of the Shrew."

Superstitious :: Free Essay Writer
Superstitious R.L. Stine who is one of Americaââ¬â¢s best-selling authors and the devilish creator of the Fear Street and Goosebumps series of horror stories for kids. Stine is who wrote the book I read, but he came back with a book for the older generation. All of Stines ideas in his books are suggested from real life. Most of his ideas came from his imagination and his memory. He now lives in New York City with his wife Jane, and teenage son, Matthew. The story took place on a small Pennsylvania College campus. Numerous of murders had taken place. Every murder was much more gruesome than the first. The detectives didn't know what had happened. The victims looked like an out of control animal rather than a human killed them. One of the main characters in this was Sara Morgan. She had just moved to Pennsylvania or school. Everything was going just fine until she met a professor named Liam O'Connor; he was another main character. Liam had a dashing romantic figure with a Irish accent, good looks, sweet charm, and a host of Old World superstitious-all of which dazzled Sara. Plunging headlong into a sudden love affair, Sara barely had time to notice the horrible events taking place on the campus. Liam was extremely close to his sister Margaret. A little too close that is. Sara and Liam soon got married after a couple of dates. Everyone said it was strange, yet, too soon for him or her. But she claimed she was in love with him. She started receiving crank phone calls, warning her to stay away from Liam. Then she received two bloody rabbit feet in the mail saying " If youââ¬â¢re going to marry Liam, youââ¬â¢re gonna need all the luck you can get." That scared her to death. When she told Liam about it, he acted like he didnââ¬â¢t care. Instead he blew all up in her face because she left out the front door and came in through the back door. Lately his superstitions had been getting out of hand. And he had been getting real mad at Sara. On their wedding night they made love by the light of sixteen candles, which was one of his superstitions. They were going on, non-stop. Then he whispered in her ear that he wanted to impregnate her. She accepted the offer without really thinking.

Japanese Medical Beliefs Essay
Japanese Medical Beliefs Medicine is all around us. It comes in all forms and all types of beliefs. Each person has their own beliefs on what medicine can do to or for the body. No matter what country one visits, there will be a medical office to assist, however their views may vary that what one may be use to. In Japan, things are no different; however, Japan has some beliefs that contrast other countries. The Japanese has received influence from other countries, such as the Chinese, but they have turned everything into their own. They have their own superstitions, traditional medicine (including how they view modern medical needs), and different types of current trends that they follow. Every country has its own superstitions. Certain things that are not allowed to happen on certain days or even certain things must be kept away because of its meanings. In 1998, an experiment was done to see if the Japanese was using the Taian-Butsumetsu superstition when discharging patients. The basis of the study was ââ¬Å"To determine the influence of superstition about Taian (a lucky day)-Butsumetsu (an unlucky day) on decision to leave hospital. To estimate the costs of the effect of this superstitionâ⬠(Hira, Fukui, Endoh, Rahman, & Maekawa, 1998). They took figures from patients discharged from Kyoto University Hospital from the beginning of April 1992 to the end of March of 1995, 3 years worth of patients. In the Japanese world, the Taian-Butsumetsu belief is related to the six day lunar calendar and affects the Japanese culture in a variety of ways since the Taian is suppose to be a lucky day where as the Butsumetsu is supposed to mean unlucky. Due to this superstition, some patients have asked to extend their stay so that they can be released on the following Taian day, which means more costs to the hospitals. To get the most accurate data, they used hospital records and calculated the amount of days that patients were released on each day of the six lunar cycle, and then estimated the costs that the extension brought on to the hospital. They also took into consideration the patients age and gender. The results showed that ââ¬Å"Of the 23677 patients discharged from the Kyoto University Hospital during the study period, 12613 (53. %) were female and 11064 (46. 7%) were male. The mean number of discharged patients was 21. 6 a day with the mean age 42. 3 years and the mean hospital stay 37. 1 days. The mean number, age, and hospital stay of discharged patients were highest on Taian and lowest on Butsumetsu. The Kruskal-Wallis test showed significant difference among the days of this cycle regarding the mean number, age, and hospital stay of discharged patientsâ⬠(Hira, Fukui, Endoh, Rahman, & Maekawa, 1998). Reports also showed that 3. 3% of the discharged patients adjusted their discharge date due to their belief in Taian. It goes on to state the estimation that the mean of a typical hospital charge was 12 600 yen a day. The extra charges the patients caused the hospital to incur in order to stay to the next Taian, amount to 7. 4 million yen a year all due to a superstition. If the patients would have shorted their stay to a prior Taian, there could have been a savings of roughly 12. 1 million yen. Another superstition for the Japanese is blood type. According to superstitions, your blood type can tell your temperament and personality. A man named Furukawa Takeji suggested a link between the two after working in a high school and observing the temperamental differences between applicants. His theory suggests that type A were generally mild tempered and intellectual, while blood types B were opposite (Thatcher). This superstition has influenced the Japanese so much that some companies have actually grouped their workforce together depending on their blood type. In the 1920ââ¬â¢s and 30ââ¬â¢s blood type grew more intriguing. Scientists in the west found that type B was common in Asia, but rare in Caucasians. As type B was typical in animals, they argued that Asians were inferior, lower on the evolutionary scale. Japan does have some forms of traditional medicine. They are required to have independent licensees for Kampo, acupuncture, moxibustion, and anma-massage-shiatsu. Kampo is only able to be performed by physicians with western medical doctorââ¬â¢s license. Acupuncture and moxibustion can be given by a person graduated from senior high school and later completed a 3 year education at one of the educational facilities specified. Acupuncture, moxibustion and anma are classified within the framework of the Japanese medical care system (Katai). Of these, Kampo seems to be the most widely used in Japan. Kampo medicine is widely practiced and is fully included into their modern healthcare system. The word Kampo means Han Method, which refers to Chinaââ¬â¢s herbal system which developed in the Han dynasty. It was used in ancient China but is believed that Kampo came to Japan from Korea in the 5th or 6th century. In 1976, it was added to Japans national health insurance plan. Although it relies on herb formulas, it uses acupuncture, moxibustion and a few other components. 70 percent of physicians in Japan regularly prescribe it to their patients (Tanaka, 2010). It has been used by gynecologists, urologists, cardiologists and even gastrointestinal specialists. In order to determine the right formula for each patient, they require a sho. This is a diagnosis based on patientââ¬â¢s symptoms and patterns of disease. In 2007 Japanââ¬â¢s Society of Oriental Medicine issued an evidence report which shows all the findings of the research published from 1999-2005. 8 papers were deemed qualified. Some double blind showings were, ââ¬Å"Hypertension related symptoms (flashed faces, etc. ): The administration of Ourengedokuto (Huang Lian Jie Du Tang) decreased hypertension related symptoms (Muli-center study of 116 facilities) Upper Gastric Symptoms: Rikkunshito (Liu Jun Zi Tang) was effective in decreasing upper GI discomfort and related complaints, such as a l ack of appetite. Irritable Bowel Syndrome: Administration of Keishikashakuyakuto (Gui Zhi Jia Shao Yao Tang) decreased abdominal pain among IBS patients. The effects were more pronounced among diarrhoea-dominant IBS cases. Muscle Cramping: Shakuyakukanzouto (Shao Yao Gan Cao Tang) was effective for reducing muscle cramping among cirrhosis patients. Obesity: 24 weeks of administering Bofutsuseisan (Fang Feng Tong Sheng San) decreased visceral fats and waist circle, as well as improved insulin resistance among obese female patients. Allergic Rhinitis: Shouseiryuto (Xiao Qing Long Tang) was effective in improving symptoms of allergic rhinitisâ⬠(Tanka, 2010). Another form of traditional medicine is Acupuncture and Shiatsu massage. Acupuncture is where extremely thin needles are gently placed in certain areas of your body. It can be uses to help balance the flow of energy through pathways in the body or can be used to stimulate nerves, muscles and tissue. It can be a more natural way of making the body feel better, without medication. Shiatsu is a massage that is used to relax people. The massage therapist uses hand, thumbs, elbows and knees to help dig into the more ââ¬Å"knottedâ⬠areas of the body. It is an acupressure therapy. By using these additional parts of the body, they can use their whole body to endure more pressure onto the person in order to offset tension. The difference between acupuncture and acupressure is that acupuncture uses needles, where as acupressure uses body part to dig into the tissue. Some people do not truly understand the alternative ways. ââ¬Å"The biggest misconception about alternative medicine is that itââ¬â¢s just a different procedureââ¬âthat one can just replace it with conventional medicine, like taking an herb instead of a pill. â⬠(Gray 2009). The Japanese also has strong views on medical beliefs. Things such as organ transplants are strongly discouraged due to Japans belief. In 1987, the Medical Association declared brain death to be equivalent to the death of a human being (Masahiro, 1995). Some Japanese doctors practice ââ¬Å"closed-door medicineâ⬠, which is where the doctor fails to properly inform patients about their condition or straight out lies to them about it. A study in 1992 showed that only 20% of terminal cancer patients knew they had cancer because of the doctorââ¬â¢s decision to inform them on the truth. This shows that 80% of patients were lied to or told nothing. Masahiro, 1995) Due to this, Through the brain death controversy quite a few people expressed great fear that in the process of the determination of brain death and transplantation no information might be given to family members, and in the worst case that the doctors might lie to family members. Some pointed out the possibility that doctors might psychologically threaten the family members if they refuse to agree to organ donations from a brain-dead relative. As time passed, it appeared that Japan accepted modern technology in almost every form except human birth and death. Research has shown that they believed a dead person goes to the next world as a soul. If parts of that body were to be donated, then body as a whole would not be together, thus making the soul unhappy in the next world. The Japanese has however become more willing to use terms such as ââ¬Å"informed consentâ⬠or ââ¬Å"patients rightsâ⬠. It appears as if Japans beliefs will simply be based off of their own cultural beliefs, as oppose to something such as the Euro-American beliefs. Due to the fast paced living in Japan, they have begun trends to help ease the stressed out society and bring forth relaxation. They have opened oxygen bars, nap salons and animal therapy. In oxygen bars, you can have personal flavored oxygen cans that can help bring you energy and provide fresh air. You can also purchase them at salons and beauty halls. The canisters, such as Big Oxââ¬â¢s helpfully informs that ââ¬Å"oxygen is an essential gas for human beingsâ⬠and claims that its 89 per cent oxygen blend (normal air contains about 21 per cent) can help boost energy, particularly during exercise (Feelgood, 2008). In recent years, major cities in Japan have opened nap salons. A particular salon in Tokyo, Napia has over 1,500 members. Fatigued office workers can take a brief lunchtime nap on a daybed there for roughly equivalent of $4. 50 (US). Sleep studies have shown that their naps should not go beyond 30 minutes because it is then more likely for them to fall into a deep sleep and end up waking up feeling extremely groggy. To help ensure that customers do not sleep beyond 30 minutes, they provide customers with coffee right before their nap. Since it generally take 20 minutes for the caffeine to kick in, they can get a quick nap in, then the caffeine will kick in and allow the person to have a more natural wake up (Faiola, 2006). Some Japanese companies have even gotten their health insurance providers to cover the fees for nap salons. If they have not succeeded in that route, they simply take naps at their desk during lunchtime. This way they are not only getting their nap in but the office lights are being turned off which is saving energy. In Japan, bathing in mineral waters is popular as a health-promotion practice. (Miller, 2007) Onsen, which is a hot spring, is in their belief to be opposite of everything in their normal crazy lifestyle. It represents an opportunity for the Japanese to melt down the hierarchical nature of society through mutual nakedness and intimacy (Onsen, 2006-7). It is pretty much a public bath with natural hot spring water for them to use in order to relax from their hectic work schedules. It is their belief that the water holds healing powers. There are a few different types of hot springs: Simple Springs, Carbonate Springs, Salt Springs, Sodium Sulfate Springs, Iron Springs, Acidic Springs, Sulfur Springs and Radium Hot Springs. Most people sit back quietly and enjoy the silence that surrounds them while bathing for roughly 20-30 minutes. The extremely acid hot spring Onsen water is believed to ease neuralgia, alleviate muscle pain and the symptoms of chronic skin disease. It also relieves chronic fatigue and stress. Since ancient times, Onsen water has been renowned to help maintain a beautiful skin. In addition to its other health and beauty benefits, the hot springs energize the metabolism. The Onsen experience is also known to calm nerves and put the bather in a relaxed, meditative stateâ⬠(Onsen, 2006-7) Unfortunately today there are only three hot spring resorts remaining. One is Kusatsu Thermal Spring which is in a small town roughly two and a half hours from Tokyo by train. It can either be visited for the day, or turned into a mini vacation. If only wanting to spend a day, you can visit one of 18 public hot springs in the town for a quick fix. Another location is Gero Thermal Spring. It is roughly three and a half hours from Tokyo by train to Nagoya, then about an hour and a half to Gifu, where Gero is located. Here, you can stay at one of the resorts or visit the public springs which allows you to test out three of the twenty. The final is Arima Onsen Thermal Spring. This final spring is roughly three hours from Tokyo then another 30 minutes to Kobe, where Arima is located. This spa is the oldest spa known to the country. Here, there is a public theme park which holds 17 hot springs. Another trend is fish pedicures. At some Onsen Springs, there are spas where you can dip you feet into the water and have these fish eat the dead skin off your feet. Although they are considered ââ¬Å"flesh eatingâ⬠they actually have no teeth, meaning that you will not get bitten. They basically suck the dead skin and cells off, leaving your skin silky smooth. No matter what country you look at, each will have its own beliefs on medicine. Some are traditional and some may by alternative. Japan is widely known for having a mixture of each. While receiving influence from other countries, Japan has incorporated other medical approaches into their own. They have their own superstitions, traditional medicine (including how they view modern medical needs), and different types of current trends that they follow.

Elevator Pitch
The concept of the Elevator Pitch is borne from the idea that if you met an investor on an elevator and only had 30 seconds to pitch your business, what would it sound like? In fact 30 seconds is about as much attention as you are going to get from an investor to begin with, so thinking in that time frame makes a lot of sense. The formula for the perfect Elevator Pitch involves three ingredients ââ¬â the Problem, the Solution, and the Market Size. The Problem Every great company starts by solving an important problem.The more accurately you articulate the Problem, the more valuable the Solution will be. Think about how NetFlix. com solved the problem of having to go to the video store in order to rent a movie. No one enjoyed having to travel back and forth to the video store for a rental, nor did they appreciate paying late fees (which we all have done, and hate! ) NetFlix solved the problem of never having to visit a video store to rent a movie and never having to pay late fees again. It was a real problem that everyone could identify with (much to the chagrin of Blockbuster! The Elevator Pitch has three main ingredients: The Problem, The Solution and The Market Size. With only the Problem in hand, our Elevator Pitch would start like this: ââ¬Å"Going to the video store is a pain. People don't like traveling back and forth just to rent a movie and they hate paying late fees even more. â⬠What's important about this explanation of the Problem is that everyone can relate to the problem. The more relate-able the problem, the more likely you are to get someone's attention to it.Think about ways to modify your ââ¬Å"Problemâ⬠so that anyone you meet could easily understand it. Itââ¬â¢s more important that the problem is relate-able than complicated. Now let's find a solution. The Solution Once you've articulated the Problem your next step is to think about how your Solution fixes that Problem beautifully. Sticking with our NetFlix example, hereâ â¬â¢s how we might articulate our Solution: ââ¬Å"NetFlix provides customers with a huge selection of movies that they can order right to their doorstep and never have to pay a single late fee for. Notice how the Solution ties directly back to the pain points of the problem, namely the fact that you don't have to leave your house and you don't have to pay late fees. A good Solution is a direct reflection of the Problem. As a side note, a Solution with no Problem preceding it is a lot less valuable. Take a second look at the Solution for NetFlix above without the Problem before it, and think about how much less exciting that Solution is without understanding the Problem that it solves. The Market SizeSolving the Problem beautifully is nice and all, but if the Market Size of the Problem isn't big enough, you're not likely get investors very excited. The Market Size explains just how big and widespread the market is, which implies how big of a company you can build by solving that p roblem. Investors want to know you're solving a painful problem in a giant market. If you can combine those two factors, you'll generate a lot more interest. Watch what happens when we reduce the size of NetFlix's Market Size by just adding a few words to the Problem: Going to the video store to rent the movie Fletch is a pain. People don't like traveling back and forth just to rent Fletch and they hate paying late fees even more. â⬠We haven't even explained the Solution yet and already you're probably thinking ââ¬Å"How big of a business could you build on helping people rent Fletch? I mean hey, it's a good movie, and probably a seminal work by Chevy Chase, but c'mon! â⬠Now let's try that again, only this time we'll use a real Market Size: ââ¬Å"For over 90 million Americans going to the video store is a pain.People don't like traveling back and forth just to rent a movie and they hate paying late fees even more. â⬠Notice how with just a small modification we ga ve you a real good indication of how big this Problem really is. 90 million Americans represent a lot of dollars spent. Even if you don't entirely understand the problem, you can certainly understand that 90 million people probably add up to a pretty big market opportunity. Picking the right Market Size is about identifying a portion of the market that is likely to buy your product.It's not everyone that's ever seen a movie; it's everyone that is currently renting movies. Maybe it's less than that if some percentage of those consumers don't use the Internet. You don't need to have the world's largest market, but be mindful of going after a market that is obviously too small (like the people renting Fletch) for fear of turning people away before they even have the opportunity to hear you out. Put it Together, then Pare it Down Now we've got a nice understanding of the Problem, Solution and Market Size. The next step is to distill that explanation down to an easy-to-remember ite-sized sound bite that still covers all the bases. Let's try a shorter version: ââ¬Å"NetFlix helps over 90 million Americans avoid driving to the video store by delivering movies directly to their doorstep without ever paying late fees. â⬠In one sentence we've tackled the Market Size, Problem, and Solution in a way people can easily remember. Most importantly, in a way you can remember when you're explaining what you do a million times over! In many cases, you'll be lucky if you get just enough time to get this one message across, so refining the message is key.Don't worry about getting it right the first time. Pitch it a few times to strangers, get some reactions and modify. It takes some practice. The Tag Line Distilling the Elevator Pitch down to one sentence isn't always enough. You'll often need something that's just a few words in order to arm others with an easy explanation of your company. You'll personally remember that 90 million Americans have a movie rental problem and that you help people avoid late fees. No one else will. Investors won't remember more than the general concept.Your advisors who mention you at cocktail parties won't be able to recite your beautiful pitch. You need a Tag Line. The Tag Line is an explanation of what you do without the details. It's how people reference you before getting into the pitch. It's how you probably remember most of the products you use today. Here's a Tag Line for Netflix: ââ¬Å"Mail Order DVD Rentalsâ⬠Notice how simple that is? That's the point. In just four words it explains what NetFlix does, without going into the details of the problem it solves or how big that problem may be.Take some time and really refine your Tag Line. Put it on your Web site, your business card and all of your collateral items. You're building a brand after all, and your Tag Line is what makes that brand memorable.

Experiment 1: Calorimetry
Experiment 1: Calorimetry Nadya Patrica E. Sauza, Jelica D. Estacio Institute of Chemistry, University of the Philippines, Diliman, Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (? T) was calculated by subtracting the initial temperature from the final temperature. The reaction was performed twice for every calorimeter. The heat capacity (Ccal) of each calorimeter was calculated using the formula, C_cal=(- H? _rxn^o n_LR)/? T[1] where ? Horxn is the total heat absorbed or evolved for every mole of reaction and nLR is the number of moles of the limiting reactant. The ? Horxn used was -55. 8kJ per mole of water while the nLR was 0. 005 mole. Table 1. Average Ccal from recorded ? T values. Trial?

After calibration, a reaction was performed in a calorimeter by each pair. A total of eight reactions were observed by the whole class. The temperature before and after the reaction were recorded. Then the change in temperature was calculated. Eac h reaction was performed twice to produce two trials. The experimental ? Horxn for each reaction was solved using the formula, H? _rxn^o=(-C_cal ? T)/n_LR [2] where Ccal is the heat capacity previously calculated for each calorimeter. The percent error for each reaction was computed by comparing the computed experimental ?

Horxn as shown by the percent error for each reaction (table 2). The discrepancies were caused by many factors. One factor was the loss of heat. The heat may have bee n released when the thermometer was pushed or pulled during the reaction. The heat may also have been lost because the calorimeter is not totally isolated. Another factor was the dilution of the solution. The pipette or test tube may still have been wet when used. However, the concentration used in solving for values was the concentration of the undiluted solution. Another factor that may have contributed to the difference in the experimental and theoretical values was human error. It was manifested when reading the thermometer or measuring chemicals with different instruments. The factors aforementioned are the limitations of this experiment. References Petrucci, R.
