By early 1770, Boston had about 15’000 a person with about 4000 British soldiers and the tension was rising. On the evening of March 5th, crowds pelted stones at British soldiers which resulted to the firing at the crowds by the soldiers, killing five inhabitants of the city. The historic engraving by John Revere â€Å"The Bloody Massacre in King-Street,† was produced. This was one of the war propaganda tools at the time. It is however not an accurate representation of the events that actually happened. The engraving shows the soldiers lined up shooting into the crowd and a poem Revere may have actually written. Revere is said to have based his engraving on the actual work of Henry Pelham. The following is observed from the engraving. The British soldiers have lined up with one of them giving the orders to shoot. This suggested the British soldiers were the aggressors. The crowd is seen reacting to the aggression when in fact they are the one who had started the attack. The expression of the soldiers on their faces is sharp while that of the colonists is innocent. These made the British look mean and as if they were enjoying the violence. In another feature of the engraving is that the laborers were dressed decently elevating their stature and how they were perceived by the general population. This clearly shows the biasness of the engraving by leaning on the side of the colonists themselves and portraying the British soldiers in bad light. This bias is also represented by the illustration of the sky which seems to shed light on the atrocities being committed by the soldiers. The unreliability of the engraving is also seen in the Illustration of Crispus Attucks who was an African American but is seen as otherwise not African American.

Animal Testing Essay Living in the twenty-ï ¬ rst century society is beginning to raise questions about the importance and relevance of issues that could very easily alter our way of living. Animal testing is one of these issues; the use of non-human animals in experiments. When an opinion regarding whether or not animal testing is ethical is mentioned in conversation or our news, citizens generally begin to question its morality. In debates, the issues on animal testing should be divided into two sub-categories: what is necessary for survival, and what is moral. If animals do feel a little pain, can you imagine how they feel? They are forced to do something that they do not want to do just because they cant actually say ‘no’. Yet, scientists, the well educated people, believe that we should keep it, so should we really get rid of it? Animals used: Many different species of animals are used in research. In 2003, the majority of procedures used mice and rats. Other mammals accounted for around 3% of the total, including 11,000 pigs, 5000 dogs and 3000 primates (for example, monkeys and marmosets). Laboratory mice are used more often in research every year than any other animal species. Mice, and other rodents such as rats and hamsters, make up over 90% of the animals used in biomedical research. In addition to having bodies that work similar to humans and other animals, rodents are small in size, easy to handle, relatively inexpensive to buy and keep, and produce many offspring in a short period of time. However, rodents may not always be the best animal to use in certain experiments. In these cases, dogs, cats, rabbits, sheep, ï ¬ sh, birds, reptiles and amphibians, or other kinds of animals may be used. All of these animals together make up less than 10% of the animals used in research. Methods of testing the drug: 1.Exposure Testing Some animals are tested by exposure testing. Animals like rats, dogs, cats, monkeys and birds are exposed to things that people would normally be exposed to. Exposure includes inhaling cigarette smoke or being in a place where furniture polish is sprayed. Exposure to microwaves, UV lights, the sun and extremes in temperature are also ways animals are tested. The results found include diseases that show up because of exposure to elements, learning disabilities that might occur (based on maze and behavior tests after exposure) and pregnancy complications that go along with exposure. These tests are usually used to make conclusions about what a humans reaction would be to the speciï ¬ c substances or conditions that the animals were exposed to. Conclusions might be that products are safe for humans based on exposure to animals or that products and elements are not safe based on what happened to the animals. 2.Skin Testing Some products, like cosmetics, are tested on animals by skin testing. In this method of testing, animals have products applied to their skin. This is done especially with pigs. The products, like cosmetics and other skin care products, are introduced to the animals skin, and the results are recorded. Most of this testing is done by cosmetic companies themselves, who are looking for any adverse reactions the products might have. Reactions they are looking for include breakouts, skin irritations, sicknesses or allergies that crop up with exposure. Research companies might be paid by cosmetic companies to test the products of competitor companies to make sure that the products they are selling will perform better. Cosmetic companies and skin care companies are also looking to test how well their products work Skin testing on an animal http://www.peta.org/b/thepetafiles/archive/tags/skin against the claims they have made for their own +corrosion/default.aspx products. 3.Injection Testing Many animals are tested with injection testing. For drug testing, this might mean injecting an animal with a drug to see what the side effects of the drug might be. Allergy medications, acne medications, seizure medications and disease medications are tested on health animals to test for side effects like sicknesses, birth defects or behavior problems. Other animals are tested by ï ¬ rst being injected with a disease or a sickness, and then injected with a course of drugs to see which drug might beneï ¬ t it the most. Diseases include AIDS, Cancer, Parkinsons Diabetes and Epilepsy. The beneï ¬ ts they are looking for include a reduction in symptoms, a cure for the disease, or a way to slow down the diseases progress. Injection testing usually measures the effects of the substance that is being injected on the animals, in order to see what results those things might have Ingected animal testing for people. http://urchinmovement.com/ 2011/08/11/the-rise-of-the-planetof-the-apes-animal-testing-goesmainstream/ 2 Nayla Khalifa AlKhalifa 4.Creation Testing Some animals are created in order to be tested, or their creation itself is the test. Scientists play with the genetic makeup of animals and attempt to create new animals. They also perform experiments on animals in utero, such as inject them with drugs, expose them to chemicals and change their genetic makeup to see if these experiments can be accomplished successfully and then to see if those results can be repeated for humans. Animals are cloned in labs to see if the cloning process works and what drugs, processes and genetic manipulations affect cloning in what way. Cloned animals are then studied to determine the effects of cloning on a general population. 5.Behavior Testing Some animals are tested in a way that is unobtrusive. Behavior tests are not usually meant to test a product or cosmetic or drug. They are tests that look at the lives of the animals and their behaviors. Some tests might include testing the speed at which mice can run various mazes or testing an animals ability to recognize colors or symbols. These tests might include exposing animals to loud sounds like music or yelling or to stressful situations including loud sounds, ï ¬â€šashing lights or strange smells or vibrations. Researchers then watch their behavior and make conclusions about what might happen to people in the same situation. Behavior tests also include studying the way a dog thinks by having him respond to commands and stimuli or testing the way another animal reacts when praised or yelled at. These behavioral tests give more information about how animals think and how their brains work, and also provide insights into why humans might have some of the same behaviors or issues as animals. What are the alternatives? There is a huge range of non- animal research techniques that, as well as being a more humane approach to science, can also be cheaper, quicker and more effective. These include: ââ€" Cell cultures Almost every type of human cell can be grown in culture and this has been key to understanding cancers, sepsis, kidney disease and HIV/AIDS. Cells grown in test tubes are routinely used in chemical safety testing, vaccine production, medicines development and to diagnose disease. ââ€" Chemical methods Analytical techniques used by chemists can be used to detect toxins in products, such as the LCMS method to replace the use of mice who are injected to detect toxins in shellï ¬ sh. ââ€" Tissue and organ culture Tissues from humans donated after surgery or even death can be used to investigate diseases and also test whether drugs might be safe and effective, before they are used on humans. ââ€" Computer models Programs run on computers can be used to predict whether a chemical is going to be harmful based on its similarity to other chemicals, or to even simulate body processes such as heart rate. ââ€" Human Volunteers Studies of humans can often be the best way to replace animals. We can now see inside peoples’ brains using imaging machines or test microscopic amounts of new drugs harmlessly on volunteers, as well as conduct large scale studies of populations to help see what might cause disease (epidemiology). Scientists are moving away from using animals but it is a slow process and they need more support. My opinion on animal testing is that we still need it but we should try to minimize the amount of animals being used and the pain the may experience even when pain relievers and anesthetics are used. We should use alternatives as much as we need to. We should not completely ban animal testing until we have a full replacement for it that works just as well or even better. Scientist are actually just trying to save someones life, I think many people in this world would see that as a selï ¬â€šess act. Personally I would rather an animal die than a cancer patient. They also test on animals as some of them are very much like humans, that means if an animal has a positive reaction towards a drug we are one step closer to curing a disease and we would all rather an animal die during research than a human. Animals are mostly used to develop medicines for the sick and have they have actually helped ï ¬ nd different treatments for cancer, strokes, and may other diseases that many people die from each year. Anyone that thinks that they are against animal testing is basically telling some cancer patients that they would rather them die then some rats. I would never ban animal testing. I ï ¬ nd that the people who protest against animal testing are an insult to the poor people that are ï ¬ ghting for their lives lying in a hospital bed some where with one chance of getting their life back by taking a drug that may have been tested on animals. It makes me feel really uncomfortable knowing that healthy people want something which will drastically decrease the standard of living of others. A complete ban on animal testing will have very serious negative effects on medical research. I believe that developing better, more effective and safer drugs is more important than sparing a few rats. Either way, if we continue animal testing ( which we are now ) too many animals are getting hurt, money is being spent, and products are still being tested, but if we ban animal testing we only have alternatives that work with only certain parts of an animals body. So, if we do either one we will still have issues.

Observational Learning of Violent Behavior Essay -- essays research pa

Today violence has become an every day experience in life. Playing video games or turning on the television, and flipping through the channels at random, you will most likely stumble upon various forms of violence. Does it desensitize or help us tolerate violence? And the most controversial issue, does it cause violence? Most humans learn by simply watching, and then imitating the action rather than trial and error or direct experiences of the consequences of our actions (this is not to say that watching and imitating is the only way of learning). This method of learning is called observational learning. The highly recognized psychologist with observational learning is Albert Bandura. Bandura’s theory states that observational learning is the result of cognitive processes that are actively judgmental and constructive opposed to mechanical copying. Bandura created an experiment to prove his theory. The experiment consisted of three different films, and four year old children that watched them separately. On each of the three films, a female adult aggressively played with a Bobo doll (hit, punch, kick, throw, etc.). The only differences in the three films were the endings. One ending showed the woman being rewarded with soft drinks, candy, and snacks, after playing with the Bobo doll aggressivel y. The other version of the film portrayed punishment by scolding and spankings by other adults, after performing aggressive behaviors towards the Bobo doll. In the last film the aggre...

How terrorism affect our economy Essay

Terrorism and terrorist activates are never intended to target an economy directly, instead it is designed to scare people who, overwhelmed by there trepidation destroy there own economy. The pliant economy of United States was misjudged in contrast with the September 11 terrorist attacks. Despite an estimated $120 billion of damage and a great deal of anxiety, one year following the 9/11 attacks considerable recovery was recorded in U. S economy. A disagreement between the Economists world wide has been shaping up over the affects of terrorism on the economy of USA, many feel that because acts of terrorism are usually aimed towards small portions of the stock of capital of a country so effect on economic activity are not very large(Enders and Sandler 2006). On the other hand, consciences of terrorism on the economy under pragmatic estimation suggest large and long term affects (Terrorism and the World Economy 40). If we review the federal budgets between FY 1998 and FY 2001 $ 48. 3 billion where available in surplus. Attacks of September 11 originated a blow to the economy of Manhattan, but not to that of Boston or Chicago. Terrorism creates a pessimistic affect on industries like air travel, hotels and insurance at large, but if we review economy’s overall performance, investment and demand shifted to other industries-especially when Federal Reserve eased credit in order to calm post-Sept. 11 markets. The immediate and the fore most impact that originate due to terrorism is the development of Paranoia attitude towards the economy through restrictive air travel and raising uncertainty, economy is drifting into a phase of recession. U. S economy has been diminishing even further after U. S invasion in Afghanistan and Iraq. Another way terrorism affected our economy is the lift in oil price which proved to be an economic jolt over the American nation who is now linking this oil situation with the upcoming elections and political agenda of American presidential candidates. The most direct damage that terrorism brought to our financial system is the deficit of U. S. government budget, which was a record of 413 billion dollars in 2004. A slight drop of $198 billion in deficit is being predicted by CBO for FY 2009 which is expected to increase moderately by 2010. If we analyze the reports released by CBO we will realize the shocking increase in the expenditure of war on terrorism over the last few years, federal finances for the department of home land security, and ever mounting cost of government beneficial social sachems such as medical & health care and social security has halted economical development. Economists are predicting an inevitable increase in red ink taxation; this is resulting in an increasing cost of housing and other basic amenities which is ultimately decreasing the consumption power of an American. (CBO) Terrorism creates a general sense of insecurity, this brings a huge expanse on U. S federal budget in shape of home land security dept, Congressional Budget Office (CBO) estimates that federal resources devoted to homeland security activities were a total of about $41 billion in 2004, roughly double the amount allocated to those activities before September 11, By 2007 Spending for the Department of Homeland Security increased by about 6 percent, to $42. 7 billion this money was required to further strengthen the borders and aviation security. General Seance of insecurity also slowed the pace of economic growth in 2007; economists strongly feel that it will slacken further in 2008. According to CBO, the consistent problems in the housing and financial markets and the high price of oil has curbed spending on household and businesses this is also ensuing decrease in the growth of GDP. Laws and policies developed to control terrorism has overwrought federal resources to a total of $2. 9 trillion for 2008, while the revenue will total $2.7 trillion, which will result in budget deficit of $219 billion, this situation will be worsening with the additional $30 billion required to sustain military activates in Iraq and Afghanistan. (CBO 10) As a consequence American nation is facing a decline in funds allocation for national health dept, education, and Environment protection, the 2007 financial budget favored spending on defense which brought an overall decline in resources allocated for developing U. S social welfare programs Another worrying line of attack in which terrorism is affecting U. S economy is the current decline of the U. S dollar. By 2007, an 8% decline was recorded in U. S dollar’s performance in index compared to its six largest trading partners. According to the predictions made by Stephen Malyon, (a currency strategist at Scotia Capital in Toronto) the current weakness in dollar should persist for the first two quarters of the current financial year, while a rise of $1. 55 in Euro against dollar was also anticipated by him. (Ellis 2008) Terrorism creates an anxiety in the midst of American people who quite frequently hear about terrorist threats and the on going war on terrorism, while a general sense of insecurity has detained the business community, and this has created a lack of confidence among the main stream investors. Terrorism has also put the burden of humongous expense that the nation had to face in shape of Dept of home land security, ever since Sept 11, while this dept controls almost all issues related to national security and U. S intelligence, an increase in the federal resources and funds devoted towards this department, and as a consequence every year a considerable decline is recorded in social benefits such as education and national health care. Other affects of terrorism on American economy at large are the red ink taxes, increase in oil cost and the decline in dollar value; all of this is contributing towards decreasing the purchase power of an average American. Economists worldwide agree that the negative aspects and the decline in U. S economy is the cost that USA is paying for the war on terrorism. More over a large number of political & economical analyst feel that the issue of terrorism is being propagated by the American presidential candidates in there political agendas which is a major cause of nervousness among the nation. Many argue today about United States aggressive strategy to counter terrorism has been a mistake and think that a defensive strategy would have been a more appropriate choice in terms of the affects of terrorism on U. S economy. Work Cited; †¢ Enders Walter and Todd Sandler. The Political Economy of Terrorism. 1st ed.
