Human Trafficking - 813 Words
Human Trafficking involves abducting and moving the victim against his or her will. Human trafficking is caused by the dangers of being in a foreign country and poverty. Both of these causes have the same effect: being a victim in human trafficking. Foreign vacationing or wanting to work in a foreign country is very common, but many people do not know the dangers of it. Many people every year hope to go on vacation or dream about living on an island in a foreign country, but they do not understand the dangers in it. Foreigners are very easy to spot out, and thatââ¬â¢s how traffickers get their hands on unsuspecting women and children. The traffickers stake out and sometimes drug the victims before they abduct them. Someâ⬠¦show more contentâ⬠¦16, 1967 ï ¢Ã¯ ¡ ï £Ã¯ ¤ As long as the mind is enslaved, the body can never be free.

People should be prepared to take many precautions when going out of the country. The people whom live in these places that have this going on should also be aware of it and should be very careful. There should also be many different ways to help others who have been victims of these sick and cruel acts, such as creating awareness of human trafficking and giving people in poverty more options.

Decision to drop the Atomic Bomb Essay Example For Students
Decision to drop the Atomic Bomb Essay The atomic bomb controversy started on August 6, 1945. The Atomic bomb was first used in combat as it was dropped on Hiroshima, Japan. The explosive power of the weapon was finally displayed. Within a few days, another bomb was dropped on Nagasaki, Japan. The atomic bomb was one of the most destructive weapons of war used in combat. It ended the seconed World War. However, the bombs used turned out to be a big controversy. President Harry Truman had many good reasons of dropping such a deadly bomb, but some people thought we shouldnt have ended the war like we did. President Truman decided to put many years of nuclear warfare research to use when he choose to use the new weapon. The atomic bomb was built as a weapon of war, the purpose of it was for a military weapon. America was at war and congress had allowed spending two billion dollars on the project. If the United States did not use the weapon, an asset, as well as a lot money, would have been wasted. Another reason Truman decided to use the atomic bomb was to end such a horrific war quickly and without the loss of many american lives. Many people did die as a result of the atomic bomb, but the amount saved if far more greater. Truman new if he decided to go on with traditional war with Japan, the amount of americans dead would be tremendous. President Truman decided that he would spare the lives of many americans by using the atomic bomb at cost of some of the enemys civilians. The Japanesse attack on Pearl Harbor brought us into a war which we had vainly hoped to avoid. We could no longer do nothing but were compelled t do something to roll back the Japenesse militariasts. Our natural right of self defense as well as our moral duty to defeat justified Trumans decision to wage the war and, ultimately, to drop the atomic bomb. Truman was a man who understood the moral issues at stake and who had the courage to strike a decisive blow that quickly brought to an end to the most destructive war in human history. President Truman had very good reasons of why to drop the atomic bomb;though, people had remained controversial to his decision. Some american people were upset we had opened a new nuclear age. They had great anxiety and fear of dropping the bomb. Some americans thought, yes, it may have end the war, but later they thought we would suffer the consequences. They felt if we dropped the bomb, which we did, it would cause the collapse of the greatest threat to world peace. In the end though, Truman fought this and knew fear is a part of the human condition and these peacful nations that learn to live with the destructive potential of nuclear power and copalle of great good. In conclusion, I feel President Truman made a good decision. He was not in a position to do anything, but allow the dropping bomb to prevent millions of american soldiers deaths. If all things are considered, Truman made the right decision. The amount of american lives, Truman saved is immeasurable. I believe the atomic bomb proved to be an extremely valuable weapon for the United States as it ended World War two. I also think though the topic of dropping the atomic bomb will always remain controversial. .

Watergate Essays (934 words) - Watergate Scandal,
Watergate Watergate, designation of a major U.S. political scandal that began with the burglary and wiretapping of the Democratic party's campaign headquarters, later engulfed President Richard M. Nixon and many of his supporters in a variety of illegal acts, and culminated in the first resignation of a U.S. president. The burglary was committed on June 17, 1972, by five men who were caught in the offices of the Democratic National Committee at the Watergate apartment and office complex in Washington, D.C. Their arrest eventually uncovered a White House-sponsored plan of espionage against political opponents and a trail of complicity that led to many of the highest officials in the land, including former U.S. Attorney General John Mitchell, White House Counsel John Dean, White House Chief of Staff H. R. Haldeman, White House Special Assistant on Domestic Affairs John Ehrlichman, and President Nixon himself. On April 30, 1973, nearly a year after the burglary and arrest and following a grand jury investigation of the burglary, Nixon accepted the resignation of Haldeman and Ehrlichman and announced the dismissal of Dean. U.S. Attorney General Richard Kleindienst resigned as well. The new attorney general, Elliot Richardson, appointed a special prosecutor, Harvard Law School professor Archibald Cox, to conduct a full-scale investigation of the Watergate break-in. In May 1973 the Senate Select Committee on Presidential Activities opened hearings, with Senator Sam Ervin of North Carolina as chairman. A series of startling revelations followed. Dean testified that Mitchell had ordered the break-in and that a major attempt was under way to hide White House involvement. He claimed that the president had authorized payments to the burglars to keep them quiet. The Nixon administration vehemently denied this assertion. The White House Tapes The testimony of White House aide Alexander Butterfield unlocked the entire investigation. On July 16, 1973, Butterfield told the committee, on nationwide television, that Nixon had ordered a taping system installed in the White House to automatically record all conversations; what the president said and when he said it could be verified. Cox immediately subpoenaed eight relevant tapes to confirm Dean's testimony. Nixon refused to release the tapes, claiming they were vital to the national security. U.S. District Court Judge John Sirica ruled that Nixon must give the tapes to Cox, and an appeals court upheld the decision. Nixon held firm. He refused to turn over the tapes and, on Saturday, October 20, 1973, ordered Richardson to dismiss Cox. Richardson refused and resigned instead, as did Deputy Attorney General William Ruckelshaus. Finally, the solicitor general discharged Cox. A storm of public protest resulted from this ?Saturday night massacre.? In response, Nixon appointed another special prosecutor, Leon Jaworski, a Texas lawyer, and gave the tapes to Sirica. Some subpoenaed conversations were missing, and one tape had a mysterious gap of 181 minutes. Experts determined that the gap was the result of five separate erasures. In March 1974 a grand jury indicted Mitchell, Haldeman, Ehrlichman, and four other White House officials for their part in the Watergate cover-up and named Nixon as an ?unindicted co-conspirator.? The following month Jaworski requested and Nixon released written transcripts of 42 more tapes. The conversations revealed an overwhelming concern with punishing political opponents and thwarting the Watergate investigation. In May 1974 Jaworski requested 64 more tapes as evidence in the criminal cases against the indicted officials. Nixon refused; on July 24, the Supreme Court voted 8-0 that Nixon must turn over the tapes. On July 29-30, 1974, the House Judiciary Committee approved three articles of impeachment, charging Nixon with misusing his power in order to violate the constitutional rights of U.S. citizens, obstructing justice in the Watergate affair, and defying Judiciary Committee subpoenas. Further Revelations Soon after the Watergate scandal came to light, investigators uncovered a related group of illegal activities: Since 1971 a White House group called the ?plumbers? had been doing whatever was necessary to stop leaks to the press. A grand jury indicted Ehrlichman, White House Special Counsel Charles Colson, and others for organizing a break-in and burglary in 1971 of a psychiatrist's office to obtain damaging material against Daniel Ellsberg, who had publicized classified documents called the Pentagon Papers. Investigators also discovered that the Nixon administration had solicited large sums of money in illegal campaign contributions?used to finance political espionage and to pay more than $500,000 to the Watergate burglars?and that certain administration officials had systematically lied about their involvement in the break-in and cover-up. In addition, White House aides testified that in 1972 they had falsified documents to make it appear that President John F. Kennedy had

World War 2 Essay
World War 2 Essay World War 2 Essay The Atrocities of WW2 | December 3 2012 | | Who is most to blame? | Article 147 of the Fourth Geneva Convention defines war crimes as wilful killing, torture or inhuman treatment, including... wilfully causing great suffering or serious injury to body or health, unlawful deportation or transfer or unlawful confinement of a protected person, compelling a protected person to serve in the forces of a hostile power, or wilfully depriving a protected person of the rights of fair and regular trial, ...taking of hostages and extensive destruction and appropriation of property, not justified by military necessity and carried out unlawfully and wantonly. Each country that partook in the Second World War had committed war crimes to some degree, along with crimes against peace and humanity. Germany is the most responsible for the atrocities that occurred during World War 2. If Germany had not been in pursuit for power, the war may have been avoided. Japan, U.S.A., USSR, Italy, Vichy France, Britain and Canada, in that order, are also to blame for the cruel ties during the war. In such a large scale global conflict, the Axis powers, as well as the Allies were at fault. The beginning of the 1930s marked the start of Nazi Germanyââ¬â¢s exploitation of power. Seeking revenge from the Treaty of Versailles, the Nazis had waged a war of aggression, conspiracies and destruction. This party was infamous for its mass murders, specifically the Holocaust. Over 12 million people were killed during this time, 6 million of those being Jewish. Adolf Hitler, the Nazi ruler, was anti-Semitic, and believed that the Aryans were a superior race. Hitler had stated, ââ¬Å"None but those of German blood may be members of the nation. No Jew, therefore, may be a member of the nationâ⬠. Hitler had ordered the extermination of Jews in concentration camps, located throughout Germany and Poland. Those fit to work were sent to labour camps where they performed hard labour for no pay. The others were sent to their death in gas chambers. Large cam ps such as Aushwitz exterminated over 6000 people a day [see Figure 1]. The concentration camps were only one of the horrendous crimes the Nazis committed during the war. On 9 November 1938, the day known as Kristallnacht, Nazi soldiers destroyed the homes and offices of Jewish citizens in Germany. The Germans had broken many treaties in the process of gaining control over Europe, including the Munich Agreement; a policy allowing Hitler to take control of the Sudetenland if in return he stopped acquiring more territory. However, in March of 1939, Hitler invaded Czechoslovakia, disobeying the Agreement. Winston Churchill, the prime minister of Britain had commented, ââ¬Å"It is a total defeat. Czechoslovakia will be swallowed up by the Nazis. And do not suppose this is the end. This is only the beginning.â⬠As Churchill predicted, Hitler went on to carry out more indictments. Germany had signed the Nazi-Soviet pact of non-aggression. The Nazis invaded the Soviet Unio n nonetheless. Experiments were often conducted on the captured Soviet prisoners of war. About 3.4 million prisoners died in these camps, 60% being Soviet. Germany had perpetrated the most crimes against peace and humanity and is therefore the most to blame for this war. Second to blame for the acts of violence in the war is Japan. Prior to World War 2, Japan had been at war with China. Japan believed that by invading China, they would be able to gain access to natural resources as well as to accommodate for its rapidly growing population. During their quest to satisfy their imperial and expansionist needs, the Japanese were responsible for numerous atrocities, including genocide of Chinese women at the Nanjing massacre, beginning on 13 December 1937. Thousands of women were victims of gang rape and murder, their bodies left on the streets completely exposed. Chinese men were also victims of the massacre. Any men who were captured

One Independent Federal Law Enforcement DHS Agency Assignment
One Independent Federal Law Enforcement DHS Agency - Assignment Example Introduction As a response to the September 11 terrorist attacks, the U.S. government signed the Homeland Security Act in 2002, establishing the Department of Homeland Security (DHS) charged with primary responsibilities in terrorism prevention and response alongside emergency planning and response (DHS, 2002). This important agency operates through various divisions including U.S Customs and Border Protection, U.S Coast Guard, U.S Secret Service, Federal Emergency Management Agency and the U.S Citizenship and Immigration Services. This study narrows down to the operations of the U.S Customs and Border Protection (CBP) division, noting the primary and subsidiary roles of the agency and how these two roles impact on the agencyââ¬â¢s ability to execute its primary responsibility. Further, preparation of agents for operations and how the agency interacts with state and local law enforcement agencies is analyzed. 1. The CBP division of the DHS is primarily charged with preventing terr orists and terrorist weapons from having access to the United States. To pursue this role, the CBP guards about 9000 miles of land border (Canada and Mexico- 7000 miles) and water border (coastal waters-2000 miles). Further, the agency collaborates with the U.S Coast Guard division of the DHS to guard 95,000 miles of maritime border. The operations of the CBP in counterterrorism are geared towards the official ports of entry in the borders while air and marine patrols are undertaken to further deter terrorism. The CBP also undertakes prevention and response against agro-terrorism and bioterrorism. At the points of entry, the CBP undertakes a number of field activities to prevent terrorism including cargo inspection, immigration inspection program and automated targeting systems. Between the border points of entry, mobile units for patrol purposes are deployed. On the air front, the agency utilizes 700 pilots and 290 airplanes several types including unmanned ones. Lastly, the marine front is backed with 360 marine agents who work in coordination with the air division to interdict and repulse any terrorist activities (CBP, 2010). With all this capacity, the CBP is an important division of the DHS in terms of the objectives of the latterââ¬â¢s formation in counterterrorism. It maintains the largest law enforcement manpower in the USA indicating prioritization made about terrorism. 2. The CBP agency also undertakes several other roles besides its primary counterterrorism activities. 3. One of these non-counterterrorism roles of the CBP are in terms of trade. Through maintenance of close relationships with the government, trade parties and foreign governments, the CBP facilitates the occurrence of legitimate trade through serving as a U.S trade laws enforcement agency. This is undertaken through prevention of counterfeit trade at the official points of entry and through patrolling non-point of entry areas. The CBP not only inspects arriving cargo (about 25 mill ion containers arriving each year at U.S seaport, airports and through rail) but also ensures revenue for these is properly collected (CBP, 2010). To further support its roles in trade, the CBP maintains a trade support network, provides traders with information for locating ports of entry, publishes trade newsletters, maintains information about import trends, commodity status reports, tariff rates, quota

Cockroaches and Hemolymph Concentration in the Body Essay Example for Free
Cockroaches and Hemolymph Concentration in the Body Essay This lab was conducted to determine the concentration of hemolymph in the body of a cockroach. It was done by making serial dilutions to make a standard graph by injecting a dye into a cockroach and determining the concentration at different times with the use of a spectrophotometer to find the optical density which is measured in absorbance. Results showed that the concentration was not within the pre-experiment research range. Introduction: Cockroaches as well as all other insects have an open circulatory system. Unlike humans who have a closed circulatory system with arteries and veins, insects do not have any arteries or veins. They have a body of internal fluids and they use diffusion to transfer nutrients and oxygen across their bodies. This process of diffusion is only made possible because of their small bodies. In practical terms, cockroaches are cheaper than vertebrates, and since they are neither furry nor cuddly their use does not anger the animal-rights enthusiasts. In terms of economics and public health, we need to know everything we can about insects because of their enormous impact on humans as crop pests, carriers of disease, pollinators, etc. But they also have a fascination in their own right. For instance, they represent the only other major group of animals that, with the higher vertebrates, have successfully conquered the terrestrial habitat. Insects and mammals have a vastly different evolutionary heritage: evolution has had to work with very different basic body plans to produce two highly successful terrestrial organism (Smith 119-139). Insects regulate their hemolymph volume by a variety of mechanisms including hormonal and metabolic factors. In an aquatic environment, insects must continuously excrete water to compensate for water uptake, whereas in a hot, dry terrestrial environment the insect must conserve water ââ¬â in both these instances, the volume of the hemolymph is regulated to prevent excessive water gain or loss. In any given insect species, the volume of the hemolymph at any particular time during the life cycle will tend to be fairly constant. However, stressing the insect, for example by exposure to very high temperatures or by starvation, will result in changes in the hemolymph volume. The Internal fluid in the insectââ¬â¢s body is termed Hemolymph it contains both blood and other fluids. The hemolymph is used to transfer nutrients, ions, and waste to different organs in the body. It also is used to defend against microorganisms that might attack the insectââ¬â¢s body. The Hemocoel houses the hemolymph where all the organs are located. My hypothesis was that the hemolymph in the insectââ¬â¢s body was about 20-40% of the body mass. Materials and Methods: In order to find the cockroachs hemolymph volume, a small quantity of concentrated dye was injected which helped one to find how much the dye was diluted. A spectrophotometer was used to find the dye concentration needed in the cockroach. A spectrophotometer worked because dyes and other chemicals absorb light of characteristic wavelengths, and the amount of absorption depended on the concentration of the chemical. Knowing the original concentration and the final concentration it was to calculate what volume (the hemolymph volume) would have been necessary to dilute the dye that much. A range of volumes was chosen extending from below to above the probable values for hemolymph volume; you can produce a standard curve for optical density of solution on which you can read hemolymph volume directly. One advantage of this was that any errors in the procedure with the cockroach were likely to be similar to those for determining the standard curve, and they therefore canceled each other out. We started off by making serial solutions to make a standard curve for dye concentrations. We put 100, 200, 300 and 400 ul of a Ringer solution mixed with 10 ul of dye. We then put 5 ul of the first tubes into tubes that had 2500 ul of Ringer solution using a pippete. We then measured the optical density (Absorbance) of our serial dilutions with a spectrophotometer at 522 nm. Then we graphed the data, we made it linear by doing 1/OD to get an equation for the line. The next thing we did is we anesthetized our cockroaches with CO2 and we weighed our cockroaches. We then injected 10 ul of dye into the abdomen of the insect. We waited until the dye was mixed in the hemolymph evenly then we took samples at different points in time at 5, 15 and 20 min in time. We injected next to the armpit of the leg and used cold capillaries to obtain our samples. We then used the spectrophotometer to measure the OD of the samples mixed with 2500 ul of ringer solution at the different time periods. We then plotted the data and obtained theà equation. Then we plugged the reciprocal of y intercept to the equation and found the x value which equals the volume. This is a graph illustration of time(seconds) Versus optical density Discussion: After the lab was done, my original hypothesis was rejected. I predicted that the cockroach would have 20-40% hemolymph concentration. This turned out to be incorrect. Our cockroach had a percentage of approximately 15%. The result is not far from the 20% range I predicted nevertheless, not specifically accurate at all. According to my prior research, an average hemolypmh is around 25 percent and makes up about 20% of the body weigh of the cockroach. According to this research, my hypothesis was correct about the concentration of hemolyph (Czpla 171-181) There is always some variation within experiments so; something that was done during the experiment possibly could have gone wrong. The variation could have been due to the lack of following the specific time or variables. It was most likely due to a human error, which my group possible overlooked. There could have been mishandling of the specialized equipment such as the pipette or the spectrometer. It is really easy to mishandle the pipet and can result in the wrong amounts of water used for the experiment. This could affect the optical density and result in excess data. Some of the equipment was old and not always properly and fully functional. In a good preparation, the three data points for optical density (OD) will lie approximately on an exponentially declining curve (dye excretion rate may be a function of dye concentration). The extrapolation back to zero time should therefore follow this curve. Often, however, the first point will be noticeably high or low compared to the trend of the later points. This is probably due to poor mixing, either because of poor circulation, or poor injection where the dye sometimes appears to be trapped close to the point of injection. In this case, the best that can be done is to extrapolate from the later points, which, since there are only two points, will have to be a linear extrapolation. My results were in an exponentially declining curve so,I can not relate any error due to the mixing. A factor, which should be discussed because it couldââ¬â¢ve provided some potential errors, is the removal of hemolymph from the cockroach during the 30-minute sampling period. This could have reduced the hemolymph volume. The error becomes progressively larger as the 5 à µl samples are removed. If mixing is incomplete, the OD may apparently increase. Another possible source of error is the distribution of the dye, that is, how long does it take for the dye to be distributed uniformly throughout the hemolymph? This could have been a potential error, it is something I remember happening during the experiment though I did not realize the implications of it at the time. As time goes by, the Optical Density in the samples taken goes down in value. That shows that the dye within the body of the cockroach is getting transferred outside of the body of the insect. The Hemolymph concentration in this cockroach is . 2/1. 3= 15% that is not within the range of the concentration that should be which is within the range of 20-40%. There might have been an error in the spectrophotometer or maybe the dye didnââ¬â¢t spread well enough within the body, which would ruin our results. The sex of the cockroach might also play a role on the concentration of Hemolymph. For the future, if I were to carry out the same experiment I would stick to my prediction but would be more careful in carrying out the experiment. I would make sure I carried out the experiment exactly right.
