The Opposite Sex by Steven Doloff Essay Example | Topics and Well Written Essays - 2500 words

The Opposite Sex by Steven Doloff - Essay Example This research will begin with the statement that the article â€Å"The Opposite Sex†, written by Steven Doloff, appeared in the Washington Post on January 13, 1983. The theme of the article was how society associated sexist stereotypes to the males and females genders, so much so that the two genders could not place themselves in the shoes of the other gender. Truly speaking, the sexist self-images of both the genders have limited their thoughts regarding the other gender. They can imagine the other gender’s roles but are not ready to adopt them. Women are slightly flexible in that they are open about men’s roles in society, and are ready to accept them. Why this perception arose, goes back to the history of feminism, which has motivated women to come out of their stereotypic personalities, and stands at an equal status as men. The reverse is not possible, nor will men let it happen. They are obnoxious toward reverse gender roles. Gender roles are society driven, and not God-has gave, and this is the main difference between sex and gender. This paper intends to interpret Steven Doloff’s article in terms of gender roles and stereotypes associated with each gender. The main focus of the paper will be on Doloff’s line, which he writes at the end of his essay, that today’s youth is â€Å"burdened with sexist stereotypes and sexist self-images†.... writing right-away, with whatever came in their minds; while, the boys went into imagination, and had a hard time sequencing their thoughts and putting them in black and white. It was not that girls were smarter than boys, nor was it a matter of intellect or energy. It was the way both the genders perceived each other. Girls seemed to be keen about the topic at hand; while, boys seemed to be unenthusiastic as if somebody had put them off by asking them to imagine themselves in the shoes of the other gender. Girls wrote more, and the boys wrote less. Doloff’s female s tudents wrote enthusiastically out of â€Å"envy of men's physical and social privileges and curiosity regarding man’s true feelings concerning women†; while â€Å"the male students tended to wait a while (in several cases half the period), in something of a daze, before starting†. It seemed like girls had been thinking about the topic all their lives, and they finally got a chance to express their thoughts out in front of the world. On the other hand, boys seemed to be dull, not being able to concentrate on how they might spend a day like a female. When we throw a look upon some instances of the writings of both the genders, we come to know how they perceived the other gender, and how our thesis statement, that we gave in the beginning of the paper, formed. Sexism, chauvinism, bigotry, gender stereotypes- we can give many names to the essence of Doloff’s students’ writings. Doloff found out that most of the girls wrote about enjoying being a male, staying out of the house until late night, looking for dates, having fun with sports, and enjoying sexual experiences.

Against Euthanasia Essay Example for Free

Against Euthanasia Essay Freedom is defined as the power to determine action without restraint . Given this definition, is the practice of euthanasia morally justifiable or wrong? The debate of freedom arises. Euthanasia is acknowledged as a mercy killing. It is the act of putting to death painlessly or allowing to die, as by withholding extreme medical measures, a person or animal suffering from an incurable, esp. a painful, disease or condition. This begs the question: does an individual have the right to decide to take another individuals life? Religious groups would ultimately argue euthanasia is a crime against life. (Citation?)The issue of morality and ethnics are proposed. Is it moral to kill someone to take them out of their pain, as opposed to letting them live suffering? This is when spirituality comes into opposition with human rights. Euthanasia is a controversial issue that compares ones quality of life to ethics. It can be viewed as a form of suicide or a form of being merciful. Even so, does humanity have the right to determine if someone should die or not? Those who are governed by a faithful belief may see euthanasia as practiced against gods will. However, others may believe mankind has the choice over their own lives (Remove comma) and that the belief of god is a theory. Economic costs and human resources are legitimate arguments as to why euthanasia may be an acceptable option. Yet, could financial problems cause one to consent under pressure? Euthanasia denotes good death in Greek. This begs the question: does a good death exist? Despite it being acknowledged as painless, arguably it is still murderous. Society is forbidden to commit murder, making euthanasia contradictive, since it is allowing one to take the life of another. (Perhaps it may be helpful here to define murder.) Medically, euthanasia is the norm and portrayed as a gracious practice. Morally, it is dissipated and seen as an immoral exercise. Even though euthanasia is a merciful killing, it does not change the fact that it is murder. This practice is unethical and unrighteous. It should be internationally forbidden and prohibited. In 1999, Dr. Jack Kevorkian was sentenced to a 10-25 year prison term for giving a lethal injection to Thomas Youk, a man who was in the final stages of amyotrophic . (Perhaps here you can explain a little bit about the disease, i.e. what it does, what this mans life was like, what kind of pain he was in, what his future (if any) would hold.) Kevorkian saw his actions as a deed. Kevorkian stated that he has helped more than 130 people since 1990. The defense party focused on the issues surrounding euthanasia, while the prosecution concentrated on Dr.Kevorkians actions associated with Michigans laws. The prosecutor stated, This case is about what Jack Kevorkian did, and what he did under the law under the state of Michigan is commit murder. This trail did not touch base on the political aspect of euthanasia, but on the ethnical side. Thomas Youk videotaped himself consenting Dr. Kevokian to take his life, yet Dr. Kevokian was still charged with committing a crime. This is proof euthan asia is wrongful. There is no difference between Dr. Kevorkian and a medical surgeon when it comes to taking a life; the practice is still murderous. The court found him guilty since his actions were unlawful; meaning in general euthanasia can arguably be found a crime. A similar case in Saskatchewan occurred when Robert Latimer murdered his severely disabled daughter, Tracy, on October 24th, 2008. The reasoning for Latimers immoral act was he could not bear to witness his daughter suffering from a severe form of cerebral palsy. He killed her by placing her in the back of his Chevy pickup, ran a hose from the exhaust to the cab, and watched her die. Latimer was convicted on November 4, 1993 of first-degree murder. The following year he was convicted of second-degree murder. This begs a question: what is the difference between Latimers actions, killing his daughter who suffers  from excruciating pain, and a doctor who was given permission from a loved one to kill an individual who is also suffering from a brutal pain? A doctor must receive authorization to kill a patient who is overly sick. Doesnt Latimer have the right to take his own daughters life, since a doctor would have had to ask him anyways to have the right to kill Tracy? Latimer supposedly saved his daughter from being in pain, which is the same reason why many individuals chose to give permission for those who are not physically in good health to undergo euthanasia. His methods were the same as a person with a medical degree. He watched an innocent individual die. Latimer was punished since his act was seen as wrongful. So why it is that euthanasia is seen as merciful killing? Many thought Latimers behavior could be compared to the act of euthanasia, since it’s perceived as a compassionate homicide. How could a man who watches his daughter die is seen as a merciful killing? Obviously it was not, which is why he was sentenced for second degree murder. Are you suggesting that these decisions be taken out of the hands of qualified medical personnel? You could make reference to the qualifications of docto rs in these situations; it could contribute to your essay. John Pearson, born in June 1980 in Derby City Hospital, was diagnosed with Downs syndrome (http:// http://news.bbc.co.uk/2/hi/health/2600923.stm.) and was left in the care of a specialized consulting pediatrician, Dr. Arthur. Three days later, Pearson was found dead. Dr. Arthur was later charged with the babys murder. He was allegedly asked by the parents to take the life of this child, whom he killed by starvation. In November 1981, Dr. Arthur was acquitted of murder (http://news.bbc.co.uk/2/hi/health/2600923. stm), due to him taking the life of a child with the parents’ consent. (If he was acquitted of murder, you cannot call him a murderer. You can refer to him as an alleged murderer, but because he was not convicted, anything else would be inappropriate.) This is proof that the practice of euthanasia is causing other individuals to believe they have the right to take the life of someone in their family whom is suffering from a disease or disability. (Are you suggesting thi s newborn was able to make their own decision as to whether or not they wanted to live with this disability? If so, why do we not allow children to make more decisions at a younger age? Why not let elementary students vote, for instance, or enter into their own legal contracts? Make sure your stances are logical and well thought out. The more times you allow an opposing view to poke holes in your statements the more difficult it will be for you to stay credible.) John Pearson may have not been as privileged (Remove comma) as others in society due to his disability, but he did not deserve to die. It can be argued that euthanasia is form of suicide. This outrages religious groups who see this practice as immoral (Remove comma) and against the word of god. Suicide denotes the killing of one self.(Citation?) Euthanasia, a majority of the time, occurs when individuals decide to medically kill someone who is undergoing crucial agony. This practice can be perceived rather as murder. Murder means to cause to die; put to death, usually intentionally or knowingly (http://www.thefreedictionary.com/commit/suicide). (This statement and the one previous should be placed earlier on in the essay. You can then make reference to it here if necessary.) Either or, euthanasia is condemned by many religious laws. The Jewish perspective states that instances of euthanasia should be dealt with as such: any form of active euthanasia is strictly prohibited and condemned as plain murder(http://www.aisha.com/societywork/science /Doctor-Assisted_Suicide.asp). Talmudic and Rabbinic sources state, One who is in a dying condition is regarded as a living person in all respect (Talmud Smachot 1:1). The Jewish religion also believes: One may not close the eyes of a dying person (Talmud Smachot 1:1). Rabbi Merri interprets this saying as, It is to be compared to a sputtering candle which is extinguished as soon a person touches it so too, whoever closes the eyes of a dying person is compared to have taken the soul (http://www.aisha.com/societywork/ science /Doctor-Assisted_Suicide.asp). Islam also criticizes euthanasia. Muslims see life as being sacred, since Allah provided it to them. Allah decides how long each human being will live, not a doctor. It states in the Quran 5:32, If anyone kills a person unless it be for murder or spreading mischief in the land it would be as if he killed the whole people (http://www.bbc.co.uk/religion/religions/islam/islamethnics/ euthanasia. shtml). The Quran 3:145 clearly establishes, And no person can ever die except by Allahs leave and at an appointed term (http://www.bbc.co.uk/religion/religions/islam/islamethnics/euthanasia. shtml). This rule also applies to Christianity. The Catechism of the Catholic Church (2003) states: All forms of suicide and euthanasia remain strictly prohibited, but questions of moral culpability and eternal salvation are left open (http://www.acu-cell.com/suicide.html). In the Orthodox Church decisively is in opposition of euthanasia and considers it as, as form of suicide on the part of the individual, and a form of murder on a part of others who assist in this practice, both of which are seen as sins. The Church does not expect that excessive and heroic means must be used at all costs to prolong dying, as has now become possible through technical medical advances (http://www.acu-cell.com/suicide.html). Depending on your citation style requirements, this quote should probably be in block format since it is longer than 40 words.) Internationally, there are over 3.3 billion Christians, Muslims, and Jews who are opposed to euthanasia (http://www.spaceandmotion.com/Theology-World-Religions.htm) . However, Secular/Nonreligious/Agnostic/Atheist groups make up 850 million of the worlds population (http://www.atheistempire.com/reference/stats/index.php). Atheists question the truth in religion; therefore they do not recognize euthanasia as a sin, or as a form of suicide. (Are you suggesting that all of these people believe euthanasia is a positive thing?) Even though theology is governed by powerful messages, it’s still not a reliable source. Religion is still seen as just a theory, since it is just a belief. Humanity has not yet seen or conversed with a higher power, so the religious information provided to mankind has not been proven. On January 11, 2003 Dr. David Jerrrey wrote a letter to the editor of the newspaper the Financial Times. In the letter he stated, Terminally ill patients often fear being a burden to others and may feel they ought to request euthanasia to relieve their relatives from distress (cite). Given economic situations, many patients and families of the patients feel pressured by medical figures to turn to euthanasia. Michael Prowse wrote in the newspaper the Financial Times, published January 4th 2003, If euthanasia became socially acceptable, the sick would no longer be able to trust either doctors or their relatives: many of those earnestly counseling a painless, dignified death would be doing so mainly on financial grounds. Euthanasia would become a euphemism for assisted murder (Michael Prowse). Many feel psychologically pressured to consent to voluntary euthanasia because they maybe a financial burden to their loved ones. However, those who do personally require euthanasia without being forced will allow this practice to continue. Humanity has the choice of fundamental principles, being they believe they should be allowed to make the decision if they want to die, since it’s their own life. There is a shortage of hospital space, so those who have slim chances of living may feel that by them dying another who has a greater chance of life can have more attention by medical care (Michael Prowse). These arguments can be seen as a valid, which may overrule the fact that euthanasia is murderous. Individuals may sympathize with those who are in great pain, and feel they cannot continue on with life. Despite these intellectual reasons, euthanasia is a form of murder, and a practice that should be banned. Euthanasia is a deliberate act of killing. Since the beginning of mankind our world has been exposed to laws that forbid murder. In the Ten Commandments, thou shall not murder, (Citation?) has influenced recent laws. This ethnical issue must be solved, but with the help of communities (Remove comma) and countries. There are two forms of euthanasia that must be focussed on: active euthanasia, or inducing or assisting in the death of a person, who is undergoing intense suffering and who has no practical hope of recovery (cite), and passive euthanasia, which is withholding life-saving equipment or treatment, by medical equipment I mean surgeries, chemotherapy and other treatments beyond basic food, water, warmth, care and personal attention (cite). Each form must be individually looked at. Passive euthanasia is what society must accept. Active euthanasia contradicts the law (Remove comma) and commandments. The money that is being put into cloning and other scientific practices should be put towards cures that can stop the diseases which cause individuals to turn euthanasia. The truth is mankind continues to play the role of god. Our world is presently exposed to cloning; organ transplants, etc. (If this is a strictly formal essay, refrain from using etc. Rewrite your sentence to something like Our world is presently exposed to such morally compromising issues such as cloning and organ transplants.) This allows one to think that euthanasia will become a dominant practice internationally. More will rely on it (Remove comma) and see it as a consideration in their decision whether or not they want to live or die. Religion does contain truth. Only nature should have the power to decide when it is our time to go, but as technology continues to advance it provides mankind with the choice to determine one’s life or death. Illnesses do cause families grief and to suffering, but if humanity started to believe in faith again, maybe euthanasia would have to significance, (This is not a logical sentence; please clarify.) since we just lack hope. A doctor diagnoses a patient with cancer and automatically the patient senses death. What happened to believing in miracles and fate? Maybe mankind no longer believes in miracles simply because our world continues to destruct by war, poverty, and violence. We now turn to an easy way out, since the fight seems too long. Euthanasia is just a way to control our population and economy. It is a homicidal act that should be immediately stopped internationally. Dr. Jack Kevorkian, Robert Latimer, and Dr. Arthur (Remove comma) were all charged with murder because they chose to practice euthanasia without medical consent. These three men were charged with murder, which proves this operation is murderous (Remove semi colon) despite it having the word medical behind it. If a doctor performs euthanasia on a normal individual it should be equally weighed because it is a deliberate act of murder. Theology condemns euthanasia simply due to it being considered a form of suicide or murder. Individuals are pressured into euthanasia because they are sick and their life becomes less important than one that is healthy.

Economic Growth of China

Economic Growth of China Introduction This paper provides summarizes of FDI in China in the past decade until 2009, It describes the overview of the Economic growth, the sources and the benefits and costs to China and foreign companies. Moreover, the paper analyses the potential impact of China to compare with other countries. This paper covers four main ideas: Firstly, there is the definition of FDI and how there are different between the direct and indirect investments. Secondly, to analyze the benefits that China will receive from FDI and case study of Hewlett-Packard. Next, how Economics China has been growing fast from 1999 to 2008 and how inflow FDI has effected to GDP growth. Finally, the last part is summary of benefit in China. What is FDI The International Monetary Fund defines foreign direct investment (FDI) as an investment that allows an investor to have a significant voice in the management of an enterprise operating outside the investors own country. For example, General Motor decided to reduce the cost of production in United State; therefore, GM invested money to build new factory in different countries such as China, Thailand and Malaysia. However, the host country has to have an equity stake at least 10 per cent or more for the voting power of the operation in a foreign country. There are two types of investments which are the direct investment such as bonds, stocks and buildings and the indirect investment such as new technologies, capital, processes, products, organizational technologies and management skills. Both investments have advantages to Chinas Economic and foreign investors. China has the population more than 1.3 billion people (1,330,044,605 as of mid-2008), and is the worlds largest number of the population. China has become the largest recipient of FDI in the third world, absorbing nearly half of total foreign investment in developing countries since 1992 (The Economist, 1999). Between 1999-2008, China had received the FDI inflows about US$ 58.52 billion which is equal to 7.32 per cent of direct investment with non-financial. At the end of 1978, Deng Xiaoping who was Chinese communist leader had new policy opening its economy for foreign firms to increase investment (Kahal, 2001). The government policies were set up for new joint ventures in special Economic Zones (SEZs) in Xiamen, Guangdong, and Shenzhen and coastal cities such as Fujian, Beijing, and Shanghai. The government also offered special incentive policies for FDI in these SEZs. As Tian said ‘The significant of Dengs policy initiatives is to make full use of market mechanisms, or re-link with the global market system, domestically as well as internationally. From this result, China has become a new market for foreign investors to encourage FDI inflows. In 2008, as shown in figure 1, China has a high of FDI inflow about US$ 92.4 billion or about 23.5 per cent of Economic growth. Non-Financial Foreign Direct Investment (FDI) Inflows between 1999-2008 Year 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 Number of projects 16,918 22,347 26,139 34,171 41,081 43,664 44,019 41,473 37,871 27,514 Growth (%) -14.6 32.1 17.0 30.7 20.2 6.3 0.8 -5.8 -8.7 -27.3 Utilized FDI ($ billion) 40.3 40.7 46.9 52.7 53.5 60.6 60.3 63.0 74.8 92.4 Growth (%) -11.3 1.0 15.2 12.4 1.5 13.3 -0.5 4.5 13.6 23.5 General Economic and Financial Indicators between 1999-2008 (All figures are in billions of RMB or percent unless otherwise indicated) Main Indicators 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 GDP 8,967.7 9,921.5 10,965.5 12,033.3 13,582.3 15,987.8 18,321.7 21,192.4 25,730.6 30,067.0 Growth (%) 7.6 8.4 8.3 9.1 10.0 10.1 10.4 11.6 13.0 9.0 How does China get the benefit from FDI? To analyze the benefits of FDI into China; There are several opportunities for foreign invertors such as low cost and productivity of labour, natural resources and opening policy. China is the worlds largest population in the world and has a high level of labour with low salaries which can reduce the cost of production for foreign companies. In addition, this chance can create of employment opportunities and learn high technology skills. For example, Hewlett-Packard which was the first Sino-American high-tech joint venture in the Chinas electronic industry built in June 1985 in China (Lou, 2000). HP offered a long-term partnership, to maintain in the four modernizations and technological transfer and invested US$6-$7 million a year in the research and development center to provide professional service and support for its clients in China (Lou, 2000). From this investment, local communities would have knowledge transfers, technology spillovers and inflow of the capital. Moreover, MNCs in China give more benefits and higher rates such as bonuses, salaries, wages, and insurances because they are larger and more productivity than domestic companies or small companies. FDI transfers high technology skills to Chinese for increasing quality of production methods. How many of investment is Economic Growth? During 1999-2008 periods, Chinas FDI increased from US$ 40.3 billion to US$ 92.4 billion and the percentage of real GDP growth also become increasing from 7.6 per cent to 9 percent at the same time. However, the number of projects by foreign firms had dropped from 41,473 in 2005 to 27,514 in 2008 because of Economic crisis such as the Asian financial crisis, increasing fuel price and unemployment rate. Top 10 Origins of Non-Financial FDI Country/Region of Origin Amount Invested 2007 ($billion) Amount Invested 2008 ($billion) Year-on-Year Growth (%) Hong Kong 27.7 41.0 48.1 British Virgin Islands 16.6 16.0 -3.6 Singapore 3.2 4.4 39.3 Japan 3.6 3.7 1.8 Cayman Island 2.6 3.2 22.3 South Korean 3.7 3.1 -14.8 United States 2.6 2.9 12.5 Western Samoa 2.2 2.6 17.5 Taiwan 1.8 1.9 7.0 Mauritius 1.3 1.5 12.1 FDI is significant element in Chinas reform and economic growth. Thats mean inflow FDI increasing effect to the volume of GDP growth. In 2008, as shown in figure 3, Hong Kong that was the highest top 10 origins of non-financial FDI inflows, received the capital of investment from foreign enterprises about US$ 41 billion and gained more 48.1 per cent from last year (Cheng and Kwan, 2000; Gao, 2005). Conclusion China has become the largest market of FDI among developing countries because of opening trade policys Deng. It has been increasing of the capital inflow by foreign firms, even though economic world is slowly growth. Indeed, foreign investors bring the beneficial opportunity on Chinas economy such as technology transfers, productivity spillovers, employment opportunities and Economic growth. Reference Cheng, K.L.

The New Electronic World Essay -- Internet Technology Technological Pa

The New Electronic World Cyberspace has become a reality of everyday life. People across the world spend significant amounts of time and effort in the construction, maintenance, and innovation of the Internet. This advancement has created two classes: those who are in control of this new culture and those who are left behind. The fact also remains that there will always be a negative aspect for every positive one. The Internet has shown us technology at its zenith and at the same time, the perverted reflection of our society. The Matrix portrays the future of our world in the way of its innovators, one group abusing the power to enslave another. In this case, the Internet advances through the direction of people intending to utilize the power for self-centered purposes. The end result is a world in which a virtual environment was created within the minds of an imprisoned class of people. There are many theories regarding the Internet today and whether it is actually providing benefit to our world, or causing more problems than its worth. The more we progress the more others, it seems, are left behind. The Internet truly has its positive aspects. From instant information at ones fingertips to the ability to communicate across the world at the cost of a local phone call, one can easily argue that the Internet has improved our world. But as in many cases, the negative aspects of a modern innovation are more easily exploited by those who consciously or not, are destroying our environment. The access to pornography, the computer viruses damaging corporate business, and the hacking that virtual thugs find humorous are all examples of abuse that create a more negative viewpoint of the Internet. The Matrix takes this theory... ... An addiction rarely can be identified until it is too late. While the theory of The Matrix was a complex one, and at times, quite unbelievable, certainly there are those who have become too reliant on the Internet for the bare essentials of life. It is true the Internet is an incredible tool for sharing information, researching truths, and conducting business, however, it is also true that the Internet is often used as a replacement for reality. These groups of people are the ones who are in danger of becoming the drones as described in the movie. These are the people that are in danger of one day waking up and realizing that they live in a world they do not truly know. Works Cited Rheingold, Howard. The Heart of the WELL.

The Ka and Molar Mass of a Monoprotic Weak Acid

The Ka and Molar Mass of a Monoprotic Weak Acid Chemistry Lab 152 Professor: James Giles November 7, 2012 Abstract: The purpose of this experiment was to determine the pKa, Ka, and molar mass of an unknown acid (#14). The pKa was found to be 3. 88, the Ka was found to be 1. 318 x 10 -4, and the molar mass was found to be 171. 9 g/mol. Introduction Acids differ considerable as to their strength. The difference between weak and strong acids can be as much as 10 orders of magnitude.Strong acids dissociate more completely than weak acids, meaning they produce higher concentrations of the conjugate base anion (A-) and the hydronium cation (H30+) in solution. HA(aq) + H20 (( A- + H3O+ With the following formula the degree to which an acid dissociates (Ka) can be calculated and given a numerical value. Ka = [A-][H3O+] / [HA] Ka is the conventional way of measuring an acid’s strength. The purpose of this experiment was to determine the Ka of an unknown acid, along with its pKa and mol ar mass. Experimental The unknown acid for this experiment was #14.The experiment began with the preparation and standardization of NaOH solution. It was calculated that 2. 00 grams of NaOH pellets were needed to prepare 0. 5 L of 0. 1 M NaOH solution. The solution was then standardized by conducting three titration trials. It was calculated that 0. 7148 grams of KHP were necessary to neutralize 35 mL of the 0. 1 M NaOH. Three samples of KHP were weighed approximating this number (Table 1). Each sample was mixed with 40 mL of deionized water and 2 drops of phenolphthalein in 3 Erlenmeyer flasks. Each flask was then titrated with the NaOH to a light pink endpoint.The volumes of NaOH were recorded, averaged, and the standardized. The molarity of the NaOH was found to be 0. 0981. Assuming a molar mass of 100 g/mol, it was calculated that 0. 3930 g of acid was needed to neutralize 40 mL of the standardized NaOH solution. This amount was weighed out on an electronic balance to full preci sion and added to a clean 250 mL beaker. The acid was first diluted with 10 mL of isopropanol and then 90 mL of water. A pH meter was immersed in the acid solution and an initial pH reading of 2. 61 was recorded.A buret filled with the NaOH solution was incrementally added to the acid solution and the changing pH values were recorded (Table 2). As the pH meter approached the equivalence point the amount of NaOH added each time was reduced. As the Table 2 shows, the pH rose significantly with the addition of little NaOH over this interval.

According to the Graphical Analysis program, Graphs 1 and 2 indicated that the total volume of NaOH at the equivalence point was 22. 30 mL. Graph 3 indicated a volume of 22. 20 mL, a difference of 0. 1 mL. Discussion Based upon the range of possible values for Ka, anywhere from 3. 2 x 109 for Hydroiodic acid (one of the strongest) to 5. 8 x 10-10 for Boric acid (one of the weakest), this experiment’s unknown acid solution (Ka = 1. 18 x 10-4) falls roughly in the lower quarter of strength. This estimate fits its titration curve. In general, strong acids quickly go from a very low pH to a very high pH, e. g. , 2 to 12, while weak acids quickly go from a lower pH to a higher pH, e. g. , 6 to 10. The unknown solution for this experiment jump from 5 to 10 pH, which is consistent with a Ka of 1. 318 x 10-4 and a weaker acid. References Darrell D.

The changes in the global pattern of tourism

The global pattern of tourism has changed drastically over the last fifty years. Changes such as the number of global tourist arrivals, distances travelled, and the cost of travel have meant that ‘tourism' is today one of the world's most important industries. There are a number of reasons for this change, for example, technology and social situation. In the seventeenth century, doctors recommended benefits of water, which triggered the building of spas. People began taking relaxing trips to these spas. When the industrial revolution struck, huge changes in transport took place, such as better rail links in the United Kingdom. These railway lines provided links to expand. Also, people began to earn more money, and with disposable income, annual holidays became increasingly popular. During World War 2, people were not allowed on beaches. Once the war had finished, people celebrated by going to the beach. This made seaside resorts become much more popular. In 1970, the jet plane carried 307 million passengers. By 2006, this had increased to a huge 2. billion! This shows just how much tourism has increased in the past half century. In 1950, international tourist arrivals were only 20 million. In 2005, it was measured to be over 700 million! Europe in particular was responsible for a considerable amount of this increase, approximately 400 million. In 2005, there were 441,528 thousand international tourist arrivals. The Mediterranean was responsible for 36% of this number. This shows that southern Spain is a very popular tourist destination. I think this is due to the climate in the Med. The Mediterranean is well known for its hot, dry summers, which naturally attract visitors. Most arrivals here are on holiday for leisure purposes, rather than business. It is not just in Europe, however, that tourism has increased. In 1990, the world saw 439 million international tourist arrivals. In 2005, this has increased to 806 million. This shows an average annual increase of 3. 3%. There are many reasons for this increase. Economic factors, such as rising incomes, decreasing costs of the flight itself – due to the expansion of budget airlines. Also, many airlines have introduced reward schemes, or loyalty bonuses, which are appealing to the customer. Social factors, such as the increase of the number of days paid leave workers can take. This gives people more spare time for a holiday. Many students in recent years, after finishing school, which to take a ‘gap year' to go travelling, before going to university, or getting a job. Finally, there are also political reasons for which tourism has increased. Some governments invest heavily in advertising campaigns to encourage tourism. Also, international sporting events, such as the world cup or the Olympics, attract millions of people from all over the globe. Forecasts from the World Tourism Organisation are showing an approximate 650 million increase in global arrivals between 2007 and 2020. Another noticeable change is the distance people are travelling to go on holiday. In 1841, Thomas cook introduce the first ever package holiday, from Leicester to Loughborough, which was only 12 miles away. These travellers attended temperance meetings. Fifty years ago, tourist arrivals in the Middle East and Africa were virtually none existent, as the travel links simply were not there. I believe one of the main reasons that tourist arrivals have gone up so considerably is due to the travel links expanding. Thanks to the invention of the train, Thomas Cook was able to expand his holidays. However, in 1970, with the invention of the jet plane, mass tourism began. There was no limit to where people could go on holiday, so the distances travelled dramatically increased here. People travel to places such as Spain, specifically the Mediterranean, as it is only 725 miles, which is approximately a 2 hour flight. Today; people can travel literally across the world, from London to Sydney, a distance of 10,552 miles. The third main change in the pattern of tourism over the last fifty years is the cost of travel. People first began taking holidays after the industrial revolution, as they had disposable income. Although prices for travel such as trains were cheaper in the 1950's, people have a much higher income in today's society, so they are much more affordable. In the early 1990's, the first budget airline was introduced. They offered low cost flights in exchange for passenger services, such as in-flight meals and extra leg room. This appealed to many working class people, who wished to go on holiday for less. Flights on budget airlines can be extremely cheap, especially if you fly on an unpopular time and date. You can purchase some flights from the UK to Ireland as cheap as 1p plus VAT. Return flights to Spain can be as cheap as i20. Package holidays also made holidays more appealing to people who were not as well off as some. They combine the cost of flight, accommodation and travel, and are usually with a group of several other tourists. Package holidays range from your typical relaxing fortnight on the beach in Majorca, to cockroach races in Brisbane! At the story bridge hotel in Brisbane, every January 26th, they race cockroaches! This tradition began in 1981, when to drunken men argued that the cockroaches from their part of town were fastest. Today, people literally come from all over the world just to race there cockroaches! Also, many people today choose to go on â€Å"all inclusive† holidays. This is when the holiday resort provides all food and drink in the price. This is appealing to people as when on holiday, many people do not wish to cook or worrying about finding places to eat. All inclusive holidays start from just i290 to Ibiza; this makes luxury more affordable for the working class. Recently, ecotourism has become more popular. This is when people travel to less economically developed countries such as Kenya, or India. They volunteer once in the country, often doing conservation work. Flights to these areas are not very expensive, as they are less popular. Fifty years ago, few people travelled far to go on holiday, as it was so expensive. Overall, these are the three key changes in the pattern of tourism. A dramatic increase in the number of global tourist arrivals, an increase in the distance travelled, and cost of travel being more affordable, have meant that tourism is very different today than it was fifty years ago. I feel that the main catalyst for increasing tourism in general, was the invention of the jet plane. Carrying 2. 1 billion passengers in 2006, it is clearly responsible for a large part of transporting these tourists. Of course, another reason for the patterns in tourism is the fact that people are earning more money. Thanks to this disposable income, more people can afford to treat themselves to a holiday. I also feel there are now more incentives to go on holiday today, such as these â€Å"package†, or â€Å"all inclusive† holidays, as these save the consumer money. Fifty years ago, people used to travel 12 miles down the road to go on holiday, today they travel to the other side of the world. I feel this shows just how big these changes in the pattern of tourism are.
