Analysis Of On Being Told I Don t Speak Like A Black

Through out history society has created many stereotypes and assumptions based on race and nationality to confine us into categories. The reality is not every individual fits a specific category because we are unique even within the same ethnicity group. In â€Å"On Being Told I Don’t Speak Like a Black Person† Allison Joseph illustrates some speech stereotypes that come hand in hand with her racial background and how even people from the same racial background and house hold don’t all sound a like. The author portrays that race and linguistic has a huge impact on our daily life and how society sees her different to others. Also, her own identity is being put in to question base on a linguistic stereotype. Furthermore, base on ones racial orientation society already have a certain expectation of what they assume the person is capable of and an expectation of how one acts like. When we put stereotypes on individuals we discrediting the individuals identity, we are making those people part of a group base on a assumption and stereotypes can not be used to describe a who group because not everyone fits into a certain category. Speech is often associate with race because some individuals believe that if the person does not sound â€Å"educated† enough the person comes from a lower class and was brought up in the so called â€Å"ghettos† and this association is often made towards someone that forms part of a minority group.

Charlotte Gilman s The Yellow Wallpaper - 1603 Words

Rough Draft Throughout history, women have been portrayed as stay-at-home wives who care of the children, clean the house and prepare meals while the men go out, work and provide for their families. They weren’t supposed to be influential, powerful individuals. Women were shown as followers rather than leaders. They were to obey their husbands and assist them at home while the men go out and work. Back then, the image placed in the minds of young women were that they would eventually get married, have kids, and stay at home, taking care of them. In Charlotte Gilman’s The Yellow Wallpaper, the narrator breaks away from society’s view on women because she compares how her husband treats her to how all men treat women. Charlotte Gilman was known for being an advocate for gender equality and feminism. Although there is no certainty that this story is about her life, it was safe to assume that parts of this story were pulled from her personal life. This story critique s society’s view on women and gives more of a feminist view on the entire concept of marriage and how women should behave. In The Yellow Wallpaper, the narrator and her husband clash over how the wife should act. While it seems like she has a mental illness, readers may interpret it as she will no longer obey her husband or society’s view on how to be a normal housewife.

The Effect of Global Warming on Thermohaline Circulation free essay sample

The Effect of Global Warming on Thermohaline Circulation Kabir Rao1 [1] Industrial activities, such as fossil fuel burning and other human activities such as tropical deforestation have increased greenhouse gas concentrations in the atmosphere. Increasing global temperatures are likely to have extreme effects on global climate and may result in species extinction, changes in agricultural production and deleterious effects on health. Studies have been conducted in recent years on the effects of increase of greenhouse gases on the thermohaline circulation. There are several hypotheses that state that the prolonged effect of global warming could eventually â€Å"shut down† the thermohaline circulation and lead to cooling in certain regions in the North Atlantic Ocean. Several ocean-atmosphere models have been used to predict the effect of increase of carbon dioxide (a greenhouse gas) concentration on ocean circulation. Two such models are discussed and their results are analyzed. 1. Introduction [2] Global temperatures have seen a dramatic increase since the Industrial Revolution. We will write a custom essay sample on The Effect of Global Warming on Thermohaline Circulation or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Several climate models have projected an increase of between 1. 1 ° C to 6. 4 ° C in the global average temperature due to the continued effect of global warming (IPCC (2007)). Apart from the resulting adverse effect on global climate, increasing global temperatures may result in species extinction, changes in agricultural production, deleterious effects on health, rise in the sea level, reductions in the ozone layer and disruption in the ice shelf. Another possible outcome of global warming is what is now termed as the â€Å"shutdown of the thermohaline circulation†. Wallace S. Broeker, the man responsible for the term â€Å"Global Conveyor Belt†, called the thermohaline circulation the â€Å"Achilles heel of our climate system† (Broeker, 1997). There is much research that focuses on the effect of greenhouse gases on ocean circulation. Two such models are discussed in future sections. Some research has shown that the transfer of heat from regions around the equator to the poles is due to the thermohaline circulation in the ocean. This implies that Europe does not have the same limate as the poles because of the thermohaline circulation. The thermohaline circulation therefore plays an important role in regulating the amount of sea ice in the Polar Regions. There are several schools of thought (Seager, Battisti, Yin, Gordon, Naik, Clement and Cane (2002)) that attribute this climate in Europe to its position with respect to the ocean basin and the warm atmospheric waves that blow up north from the tropics. Rhines and Hakkinen (2003) c hallenged this claim. According to Rhines and Hakkinen, â€Å"it is the existence of the oceanic heat transport that allows the maritime effect to operate in the northern North Atlantic and to create a milder European climate than in the North America; without the heat transport, ice would likely extend over much greater areas of ocean and land†. Much research is currently focused on the role of ocean circulation in the supply of heat to Europe. 2. Thermohaline Circulation [3] Ocean circulation is commonly divided into two parts: the thermohaline and the wind driven circulation. In other words, circulation in the oceans is partly due to wind stress, and also partly due to changes in density because of changes in temperature and salinity. The term â€Å"thermohaline† originates from thermo for heat and haline for salt, which together determine the density of the water mass. [4] Thermohaline circulation originates in specific areas of the North Atlantic and in the Weddell Sea of the Southern Ocean. In the North Atlantic, the evaporative cooling effect of winter is responsible for cooling the upper layers of seawater, increasing the salinity thereby increasing density and causing sinking. The sinking cool water is the North Atlantic Deep Water (NADW). The denser NADW flows southwards into the ocean basins. The bulk of the water upwells in the Southern Ocean, while some of the deep water causes further upwelling in the North Pacific and Indian Oceans. This movement of the deep water forms a giant conveyor belt that covers a large part of the open ocean (figure 1). The Gulf Stream, for example, which is largely driven by thermohaline circulation, transports warm water from the Caribbean northwards. Figure 1: Thermohaline Circulation (Source: Frakes, 1992, figure 10. 1, p. 186, as taken from Kerr, 1988). 3. Global Warming [5] The Intergovernmental Panel on Climate Change (IPCC), in February 2007, submitted a 21-page report assessing the effect of global warming on global climate. The report stated that: â€Å"most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations†. Emission of infrared radiation warms the Earth surface; the phenomenon is known as the Greenhouse Effect. The dominant infrared absorbing gases in the Earth’s atmosphere are water vapor, carbon dioxide (CO2) and ozone (O3). The interactions between greenhouse gas molecules and radiation can be explained by quantum mechanics. CO2 and O3 molecules have vibration motions whose quantum states can be excited by collisions at energies encountered in the atmosphere. Industrial activities, such as fossil fuel burning and other human activities such as cement production and tropical deforestation has increased the carbon dioxide concentrations in the atmosphere. CO2 is also a byproduct from automobiles, airplanes and building constructions. The importance of CO2 as a greenhouse gas is very apparent and is therefore used as a parameter in determining the effects of global warming. 4. Review of models used to simulate the response of the Thermohaline Circulation to increasing CO2 [6] Several coupled ocean-atmosphere models have been used to simulate the response of ocean circulation to the increase in carbon dioxide in the atmosphere. Manabe and Stouffer (1993) conducted one such study; a coupled ocean-atmosphere model was used to simulate the increase of CO2 in the atmosphere. Three integrations over a period of 500 years were conducted. In the first integration the atmospheric concentration of CO2 was kept constant. The second and third integration involved increasing the atmospheric CO2 at a rate of 1% per year, until it reached twice the original value at the 70th year (for the second integration) and four times the original value at the 140th year (for the third integration) and was maintained constant thereafter. The change in CO2 concentration caused the gradual disappearance of the thermohaline circulation while doubling and quadrupling the concentration of CO2. Most notably, in the North Atlantic Ocean, the thermohaline circulation nearly vanished during the first 200 years in the 4xCO2 integration (the integration carried out while quadrupling the CO2 concentration in the atmosphere). During the first 140 years of the 4xCO2 integration, the thermohaline circulation rapidly weakens and continues to do so even after the concentration of CO2 is held constant. The integration also showed a decrease in the formation of Antarctic Bottom Water. The result of this integration shows that the gradual disappearance of the thermohaline circulation leaves wind driven, shallow cells in the subtropics of the North and South hemisphere. Similar effects were observed in the 2xCO2 integration. The thermohaline circulation shows weakening intensity during the first 70 years of simulation, which continues until the 150th year, during which there is no change in the CO2 concentration. But in the 150th year the thermohaline circulation slowly begins to regain its original intensity, although not quite achieving it. 7] Manabe and Stouffer concluded that the weakening of thermohaline circulation in the 2xCO2 integration is not due to its instability, but rather due to the adjustments made by the mechanism to the â€Å"evolving density structure† of the models Atlantic Ocean. This is apparent in the manner in which the circulation slowly regains strength in the later part of the 2xCO2 integration. This does not happen in the 4xCO2 int egration, and the thermohaline circulation shuts down. There were also notable changes in the Weddell and Ross Seas, where the circulation became weak and shallow. This in turn caused weakening of the deep-water formation and the northward flow of bottom water in the Pacific and Atlantic Oceans was affected. This weakening of the thermohaline circulation is attributed to â€Å"the capping of the model oceans by relatively fresh water in high latitudes where the excess of precipitation over evaporation increases markedly due to the enhanced poleward moisture transport in the warmer model troposphere†. [8] Schmittner and Stocker (1998) used a simplified coupled atmosphere-ocean model to study the possible effects of greenhouse gas emissions. The findings were similar to Manabe and Stouffer, with the model exhibiting a threshold value of CO2 concentration beyond which the thermohaline circulation shuts down and does not recover. The concentration of CO2 is doubled here, and exhibits a shutdown; however the model is less sensitive than that of Manabe and Stouffer. The model shows that the thermohaline circulation breaks down for a value of 750 ppm or higher. An equilibrium state is reached characterized by the absence of deep-water formation in the North Atlantic. 9] Manabe and Stouffer (2003) revisited the effect of carbon dioxide on thermohaline circulation by conducting several integrations using a coupled atmosphere-ocean model for a time period varying between 4000 years to 15000 years. Similar to the study carried out in 1993, the concentrations of CO2 are doubled, quadrupled and halved. In each experiment â€Å"the response of surface temperature increases with increasing latitudes†. In the 2xCO2 experiment, thermohaline circulation shows weakening before intensifying around the 200-year mark. It fully regains its original intensity in the 600th year. The 4xCO2 experiment shows the thermohaline circulation reacting in a similar manner as earlier noted, however, it regained its intensity around the 1000-year mark. The weakening of the thermohaline circulation in the 2xCO2 and 4xCO2 experiments is attributable to reduction in the surface salinity of the North Atlantic Ocean. With the warming of the troposphere (due to increased CO2 concentrations), the moisture content in the air increases; this in turn enhances the transport of water vapor in the troposphere towards the poles. The precipitation in the high latitudes goes up by a fairly high amount, which reduces the salinity and density of the North Atlantic waters. 5. Conclusion [10] There are several hypotheses that state that the continued effect of global warming could eventually â€Å"shut down† the thermohaline circulation and lead to cooling in certain regions in the North Atlantic Ocean. Global warming could lead to an increase of freshwater in the upper oceanic regions, by melting glaciers, and thereby increasing precipitation into the ocean. This increase in freshwater could have an adverse effect on the thermohaline circulation which, as mentioned earlier, is driven by changes in temperature and salinity. In 2004, NASA satellites recorded what seemed to be the slowing of the North Atlantic current. On April 15 of that year, NASA released a press statement stating that the â€Å"slowing of this ocean current is an indication of dramatic changes in the North Atlantic Ocean climate†. A study of the ocean circulation in the North Atlantic by Harry Bryden (2005) revealed that â€Å"Atlantic meridional overturning circulation has slowed by about 30 per cent between 1957 and 2004†. Bryden’s finding was viewed with speculation by the scientific and oceanographic community, especially since measurements conducted post 2005 showed a significant warming of the North Atlantic Current. However, the current overall climate is definitely changing; in particular sea-ice formation is less because of overall global warming. Bryden predicts that the shutdown on the thermohaline circulation could have severe repercussions on Europe, in that the temperature would change drastically. There could be major climatic changes such as an increase in floods and storms. Warming or rainfall changes in the tropics or the poles could occur. While the rest of the scientific community felt Bryden’s findings were not credible, Detlef Quadfasel (2005) felt that there were a few observations that supported Bryden’s work. Quadfasel pointed out that climatic records have shown drops in air temperature by 10 °C in a few decades possibly caused due to abrupt changes in ocean circulation. Global warming is a very real threat to the human race. The question we face is whether global warming is in fact to going to affect the thermohaline circulation. Even though there is a large amount of research that is being conducted in this area, there is an equal amount of opposition to it. Jaworowski (2007) has called the increase of CO2 concentrations the â€Å"Greatest Scientific Scandal of our Time†. Jaworowski claims that the IPCC assessment of global warming in 2007 was purely a political move, â€Å"prepared by governmental and United Nations bureaucrats†. In another article in 2007, Jaworowski also claimed that the increase of CO2 is not due to human activity but by atmosphere-ocean gas exchange and other causes of natural climatic fluctuations. Numerical models may provide a fairly decent idea of the functioning of systems, but there is always the danger of erroneous statistical methods and the use of boundary conditions that don’t necessarily reflect the real world. However, at the risk of sounding trite, prevention is better than cure. The risk of man entering a new ice age is very real as of now, and will remain so until research shows otherwise. There are studies that speculate that the shutdown of the thermohaline circulation is what previously led to the Younger Dryas (the big freeze) period (Schiermeier, 2006). Man may enter a new ice age; ironically, because of global warming.

The Threat Of Nuclear Weapons Essay Research free essay sample

The Threat Of Nuclear Weapons Essay, Research Paper Ever since the first atomic arm was built in 1945, atomic war has been a menace. The two major atomic powers in the universe today are the Soviet Union and the United States. If a war of all time broke out between the two, which involved the usage of atomic arms, the whole universe would endure from the effects. In this study I am traveling to turn out that atomic arms are a menace to all of us. A atomic arm is any device that causes an detonation by the release of the energy in an atom. They are much more powerful than any conventional or # 8220 ; non atomic # 8221 ; arms. Nuclear arms are divided into two groups: fission arms, which are frequently called atom bombs, and thermonuclear or merger arms, which are frequently called H bombs because that is what they are made of. FISSION WEAPONS Fission arms cause an detonation by the splitting of atomic karyon. We will write a custom essay sample on The Threat Of Nuclear Weapons Essay Research or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This happens when a neutron collides with the karyon of an atom. The protons in the karyon are transformed into a great sum of energy and two or three more neutrons are sent out, which go on to divide other karyon. If this continues a procedure called a concatenation reaction will happen. When this happens a fission detonation is the consequence. To organize a concatenation reaction, a certain sum of stuff is needed. This sum is known as the critical mass. If the sum is excessively little it is known as a subcritical mass. The critical mass of a material depends on its pureness. The stuffs used in doing fission arms are uranium and Pu. They are the lone elements able to be used in doing a fission arm. There are two different ways to do a fission arm: the gun-type method and the implosion method. In the gun-type method, two pieces of stuff, each holding a subcritical mass, are placed at opposite terminals of a metal cylinder. One of the pieces has a powerful, nonnuclear explosive behind it that explodes on impact and drives the piece into the 1 at the other terminal. The atoms in the stuff the collide and get down a concatenation reaction. In the implosion method a ball of either uranium or Pu is surrounded by a big sum of nonnuclear explosive. When triggered it compresses the atomic stuff, which besides causes a concatenation reaction. FUSION WEAPONS Thermonuclear or merger arms get their destructive power from the combine of light atoms. Hydrogen, the lightest component, is used in doing merger arms. When the atoms of the component fuse, they release a great sum of energy. The lone job is that the vitamin E lement must be heated to a temperature of 50 million grades Celsius. The lone manner to make this, without utilizing more energy than is produced, is to utilize a fission detonation. So, a ball of H is surrounded by either U or Pu and so by a non atomic explosive. When the explosive is set off it causes the U or Pu to fission, which in bend causes the H to blend. History In 1939, the U.S. authorities became concerned that the Nazi Germans may be capable of constructing a atomic arm, so upon fall ining World War II, the United Sates began a secret operation called the Manhattan Undertaking to construct their ain atomic arm. The first experimental atomic arm was exploded on July 16,1945, by J. Robert Oppenheimer. It was a 22 kiloton implosion-type device. This trial convinced the U.S. authorities that atomic arms could be used in war. On August 6, 1945, the United States used the first atomic arm on the Nipponese metropolis of Hiroshima. It was a 13 kiloton gun-type fission bomb. Three yearss subsequently, the United States dropped a 22 kiloton implosion-type fission bomb on another Nipponese metropolis called Nagasaki. On August 14, eight yearss after the first bomb was dropped, the Nipponese surrendered, which brought an terminal to World War II. Effects The three chief effects that would follow a atomic detonation are blast, thermic radiation or heat, and radiation. The really first thing to go on is the formation of a bolide. The fireball gives off the thermal radiation that vaporizes anything within a one-fourth stat mi and ignites flammable stuffs within 10 stat mis. The thermic radiation can do oculus hurts every bit good as tegument Burnss called flash Burnss. Between 20 and 30 per cent of the deceases at Hiroshima and Nagasaki were caused by flash Burnss. When the bolide begins to disperse it signifiers a blast moving ridge that travels off from the detonation at velocities up to 400 stat mis per hr. This destroys most edifice within 6 stat mis. It besides kills most people within 3 stat mis and badly injures or kills most people up to 6 stat mis off. Then comes the radiation. It is made up of neutrons that were left over after the detonation. When these neutrons come in contact with populating cells they damage or even destruct them. A individual exposed to big sums of radiation will normally decease. Some scientists believe that the dust and fume from the fires after a atomic war would do a worldwide chilling of the planet, which is known as a atomic winter. For this ground, the states at war would non be the lone 1s to endure.
