Abstract
A look at the process of identifying disease-causing genes. The author examines the advantages of such progress for both individuals and the general population. The author argues that families with a high risk of colon cancer will benefit from this type of knowledge.

From the Paper
"Cancers come from the interplay of multiple changes, or mutations, in several different genes, in combination with environmental factors such as diet or lifestyle. Colorectal cancer is the second most common cause of death from cancer in the United States, (Digestive Health Specialists, 1995). More than 500,000 people worldwide (HHMI, 1995) and 131,000 Americans are diagnosed with colon cancer each year. Unfortunately, more than 54,000 Americans die each year from this disease. Colorectal Cancer strikes men and women nearly equally, (The Associated Press, 1998)."

Abstract
This paper presents the causes and effects of air pollution. Other stratospheric research is concerned with the downward trends in global ozone that have recently been measured over populated regions in the mid altitudes. The author focuses on the various factors associated with global warming.

From the Paper
"Air pollution is any visible or invisible substance found in the air that is not part of the normal composition of air. Some air pollution is natural and has always been a part of the earth's history. However, over the past one hundred years or so, pollution created by humans has become a major environmental problem. Natural air pollution has been around for millions of year. Dust and a variety of gases from forest fires, volcanoes, and decaying material in rivers, oceans, and other bodies of water continually enter the atmosphere. Sometimes this natural pollution can have dramatic effects. Air pollution is a major factor in causing humans to get ill. Tuberculosis, bronchitis, heart and chest diseases, stomach disorders, asthma and cancers can all be traced to chemicals in the air. Pesticides and fertilizers release gases and particles into the air which poison people and kill animals."

Abstract
The paper discusses the complex interplay of genetic predispositions, the environment and physical factors in the development of schizophrenia. The paper then details the uncontrollable biological, genetic and environmental factors as well as the controllable genetic and nurturing factors and highlights how their role is still unclear in causing schizophrenia to manifest itself.

From the Paper
"Schizophrenia is one of the most severe chronic mental illnesses an individual can face over the course of his or her lifetime. People with schizophrenia can suffer a wide range of debilitating symptoms, including hearing voices that are not really there, feeling as if their thoughts are being controlled by outside forces, fearing that their minds can be read against their will, or they can exhibit other paranoid symptoms that alienate the individual from the rest of society. Schizophrenics often find it difficult to organize their thoughts and communicate with other people. Instead, they may speak with jumbled and disordered phrases (Spearing, 2002)."

From the Paper
"The United States tried to stay away from the War, but it finally became involved late in the game. United States troops worked with the other countries to force Germany to back off from the problems that it was causing, remove troops from other countries, and give restitution to many of the countries that it had wronged through its actions. The Treaty would have given much to all of the countries, including the United States, but it was not to be. Eventually, the United States Senate rejected the treaty of Versailles because it was fearful of becoming involved in European wars. In addition, the treaty was rejected because there was a great deal of Republican resentment when it came to Wilson's close wins of the elections of 1912 and 1916. Because of this, the United States chose not to enter into the League of Nations, which weakened it very much (Americanization, 1925)."

Abstract
This paper studies the causes of the American Civil War. While most historians maintain that slavery was the main cause of the war, this paper argues that slavery was only responsible to a certain extent and that there were complex political and economic factors which played an important role in the Civil War. The writer discusses the South's waning ability to maintain its army of slaves and asserts that the North's growing industrial power also fueled the conflict. Political factors, including the issue of equal representation in the Congress and states' autonomy, are considered as possible causes of the war in this paper.

From the Paper
"Civil war is the most momentous and crucial period in the history of America. Not only did this war bring an end to centuries of slavery in the country but also gave way to numerous social and political changes. The country had already been torn by the negative trend in race relations and numerous cases of slave uprisings were taking their toll on the country's political and social structure. While slavery is cited as the most common cause of the Civil War, it is believed that there were several other factors involved. In other words, though slavery was the major cause it was certainly not the only cause. Civil war and abolition of slavery have become synonymous terms as the former led to the latter. But still some historians maintain that slavery has been turned into a too convenient excuse in connection with the Civil War."

Abstract
This paper examines the causes of serial killer Jeffrey Dahmer's murderous depravity. The paper discusses the defense attorney's insanity defense and details the biological causes, genetic disposition, mental disorders, sociological and economic causes.

From the Paper
"The Causes of Crime. Summing up the case for his client's insanity, serial killer Jeffrey Dahmer's defense lawyer, Gerald Boyle, painted a chilling picture with his words. Skulls in a locker, cannibalism, sexual urges, drilling, making zombies, necrophilia, drinking alcohol all the time, trying to create a shrine, lobotomies de fleshing, calling taxidermists going to grave yards and masturbating. This is Jeffrey Dahmer; a runaway train on a track of madness."

Abstract
This paper presents the causes of the Black Death, and explains how it was able to spread so far and so quickly. The writer maintains that changes in population in part caused the Black Death because of trends in urbanization and emigration. The writer discusses that population changes also changed the standard of living, which then brought about a high number of social and cultural developments.

From the Paper
"Bridbury describes the Black Death as "an assault on the social system at its base which was infinitely deadlier than any which it had sustained at its apex". The plague not only caused high rates of mortality but also prevented many people from marrying or having children (Nightingale 34). All aspects of the Black Death have to be seen in terms of trends. "

Abstract
This paper examines "The Glorious Cause: The American Revolution," which reveals the complexities of the years between the signing of the treaty of Paris in 1763 and the election of George Washington in 1789. The author points out that the goal of Middlekauff's book was to analyze both the achievements and failures of the American Revolution. Some of the topics that are covered include detailed analysis of British debate about the colonies, the causes of the war as well as the evolution of the American Constitution. According to this author, Middlekauff does an excellent job of researching the different people who were intimately involved in this period in history, showing how both their strengths and their weaknesses affected this period in American history.

From the Paper
"This work, a narrative historical study of the American Revolution, and the first volume to appear in the Oxford History of the United States, reveals the complexities of the years between the signing of the treaty of Paris in 1763 and the election of George Washington in 1789. Although he does not intend his title to be ironic, the author recognizes that the cause of the American revolution "had its inglorious side, and the Americans' manner of advancing it was sometimes false to the great principles they espouse." (vii) Middlekauff s purpose is to present both the achievements and failures of the American revolution. His thesis is that our patriots and revolutionaries were not perfect, yet in learning "to see things as they are and to imagine how they might be," (665) they created a vision , fought for noble causes, endured their own imperfections and created the foundations for our country."
