Abstract
This paper is divided into two parts. The first part distinguishes between glacial erosion and weathering and the second part discusses the varying influence of the factors affecting the rate and type of glacial erosion. The paper shows that the main type of glacial erosion is abrasion and the characteristics of both the bedrock and the abrasive rock have a large influence on abrasion rates.
From the Paper
"The concept of glacial erosion can be considered using the ?systems approach?, with the factors that influence the erosion as the inputs, the type and rate of the erosion itself as the processes, and the resultant landforms and characteristics as the outputs. The type of erosion that has the largest effect on the landscape is abrasion. Abrasion is the process by which entrained, subglacial debris grinds against the bedrock as the glacier moves, and wears the bedrock away as a result. There are three factors that are essential for abrasion to occur."

From the Paper
"Streambank erosion is one of the important and often neglected environmental problems. If not properly maintained the river and the stream banks can be easily eroded by the sheer force of the flowing water during the heavy raining season. The precarious situation, which results as a consequence of erosion, cannot be taken lightly. It is these stream and rivers, which replenish the water needs of the people. Conservation of this vital natural source is an important task and the responsibility lies with man. Let us now briefly analyze the problem of stream bank erosion and the remedial solution."

Abstract
Never before in the history of mankind have we faced an environmental dilemma with the worldwide effects of soil erosion. The problem is so severe, that many experts fear the land will not be able to produce enough food to feed the world's population in the next century. The paper discusses the problem as two fold - marginal land and deforestation. Much of the world's land is marginal sandy desert and sub-desert. In order to feed and house their growing populations many countries in South America, Asia, and Africa clear the world's forests to create more grazing land. The paper shows that, although much of this land has rich soil, the effect of deforestation is an increase in soil erosion. Once the trees are removed, the soil erodes and soon becomes marginal. Combined this with the problem of acid rain, other forms of pollution, and over population, and it is obvious we are entering a time of intense food scarcity.
From the Paper
"In order to preserve life for future generations, we must preserve the soil. Conservation and research are the keys to the future. Conservation and improving soil quality will prevent food shortages in the future. The quality of food today has decreased to dangerously low levels. In spite of increased knowledge about nutrition and advancements in medicine, people today are not as healthy as previous generations. We suffer from nutrient deficiencies related to the poor quality of soil."

Abstract
This paper provides an overview of riprap, which is the most common method of providing erosion control and bank protection on streams and river banks today. A summary of the research is provided in the conclusion. A table and relevant graphics illustrating riprap in action are also provided.
From the Paper
"Watershed management and erosion control have assumed new levels of importance in the 21st century. The presence of water in soils essential to the growth of forests, and improved water yield and quality are becoming increasingly important management objectives on many forested lands today. The fundamental principle of watershed management where erosion threatens is the maintenance of continual cover. This same principle applies to stream and river bank protection, where bridge foundations must be fortified from scouring and the ravages of floodwaters. This paper provides an overview rip rap, which is the most common method of providing erosion control and bank protection on streams and river banks today. A summary of the research is provided in the conclusion."

From the Paper
"In the United States, extensive barrier.beach systems occur along major portions of the Atlantic and Gulf coasts. These fragile coast lines are in a continual state of flux. Beach erosion and accretion can result from both natural and man.made causes. Sea level change, storms, and development may all significantly impact these environments. On Long Island, New York, beach stabilization has repeatedly been attempted. Such efforts typically meet with varied success. In fact, many believe that the island's past stabilization projects have actually contributed to its current erosion problems. Geologically, Long Island consists of moraine sediments deposited by glacial drift. This mixture of crystalline gravel and boulders was scraped up in New England, carried several ... "

Abstract
This paper presents an analysis of North Carolina 's erosion of sand dunes. The author examines the causes and solutions to the problem and provides a brief overview of how sand dunes are formed.
From the Paper
"The erosion of North Carolina?s sand dunes causes definite and easily recognizable problems for North Carolina?s coastal communities. The erosion of sand dunes and beaches from North Carolina?s barrier islands and mainland coast causes problems for residential and commercial developments, which rely on these dunes and beaches for protection against storm surges. While hurricanes and strong storms have been few this year, in past years these storms have devastated coastal communities with flooding and strong winds, causing tens of millions of dollars in damage in the past decade. (Orrin 142) The best prevention against damage to homes and businesses is the protection and replenishment of sand dunes. It is important to remember that ?nature maintains the dynamic equilibrium of the beaches through the unceasing trade of four factors.? These factors are material, energy, shape, and sea level. (Kaufman 15) Dune erosion is a major problem for North Carolina coastal communities, but new preservation methods and building codes cause less damage to dunes and homes and allow damaged dunes to be repaired or replenished."

Abstract
The paper discusses the Patriot Act and how some approve the law's measures for homeland security, while others have criticized its potential to erode civil freedoms. This paper examines both parts of this argument, with a specific focus on the wiretapping of phone calls and spying on electronic mail. The paper looks at the benefits of authorizing government spying and wiretapping and also examines the criticisms of domestic spying. The paper concludes that given the current political and security climate, domestic security could be adequately protected without resorting to wiretapping and other measures that endanger civil liberties and personal freedoms.
From the Paper
"In fact, the NSA has prevented several attacks through eavesdropping. Jihadist Jose Padilla, for example, was successfully caught before he exploded a dirty bomb to spread radiation around an American city. NSA eavesdropping further foiled plots to bring down the Brooklyn Bridge and to plant more bombs in pubs and train stations around Britain. NSA insiders supposedly found that domestic spying has "been successful in detecting and preventing attacks inside the United States" (qtd in Krauthammer)."

Abstract
This paper examines the issue of the "dumbing down" of the American people by means of technological "progress." The paper states that American society is becoming overly obsessed with technological advances and entertainment media with a goal of making life better. However, the opposite is occurring: The reduction of the effort needed to succeed is causing a downgrade in human intelligence and the drive to learn. The paper questions whether this can be blamed on machinery created with the original intention of making life easier, or by our educational system which encourages this relinquishing of academic and leisurely thought. The paper concludes that, in order to counter this trend, several changes in attitude must be made. First, the paper suggests that the misplaced belief that all changes in technology are an improvement must be diminished. Second, the paper stresses the fact that mass media should be seen merely as a form of entertainment. Most importantly, the paper advocates improving our knowledge and understanding of the world around us.
From the Paper
"Furthermore, the educational system is deteriorating and busy parents with full time jobs no longer have time to tutor their children in the methods of the old world, with one on one interaction. These days it seems much more convenient to place the child in front of the television set watching shows presumed to be educational, such as "Sesame Street" or "Blue's Clues", while the mother or father do other, seemingly less important things. It is true that the above mentioned shows are much better for the young mind then violent or explicit shows, which are also sprouting up on every channel, but this method of teaching only forces them to depend more heavily on television for education and entertainment. It is, for the children, just another form of passive learning, another topic that Bradbury tackles in Fahrenheit 451. In the beginning of the novel, Clarisse describes the current educational system as completely unsocial. As she says, "they just run the answers at you, bing, bing, bing, and us sitting there for four or more hours of film teacher." Moreover, at a later part of the story, Mildred and her friends are discussing how to care for children and Mrs. Bowles makes a rather disturbing statement. She says "I put up with them when they come home three days a month; it's not bad at all. You heave them into the 'parlor' and turn the switch..." These references to television in this work of fiction are fairly worrying, as it is no longer such a fictional theory. This form of education is becoming more and more feasible for the near future. Parents already just "heave their kids in the parlor and flip the switch" so who's to say that schools will not soon also take on these apathetic teaching methods. Rather than teach young ones to amuse themselves in ways that will benefit them, the kids of today are taught that television is the source of all significance, and with the short attention spans of today, even television shows must be careful not to be overly verbose. A child must be taught that activities such as reading, which expands the mind and inspires thought, and playing with other children, to teach them valuable social skills, are far more important than vegetating in front of a box with moving pictures."

From the Paper
"The Yosemite Valley is the product of many geological forces. One such is glacial scouring, which left the spectacular glaciated granite terrain that can be seen today. Valley glaciers have been described as "tongues of ice in mountain ranges [that] start in ice-worn rock basins called cirques". In these cirques, old snow develops into firn, or nev?, a "mass of ice pellets compacted by the weight of the snow above".
As more snow falls on the firn, it spills over into the valley below, filling it with ice. As this ice moves across the landscape, it collects rock debris, which polishes and scours the valley walls and floor. This scratching action leaves a definitive calling card in the form of grooves that identify ... "

Salt Weathering, 2008.
Researches and examines the differences in salt weathering upon chalk limestone coasts versus hard-rock coasts.
1,615 words (approx. 6.5 pages), 7 sources, APA, $ 52.95
»
Click here to show/hide summary
Abstract
This paper explains that the erosion of limestone and hard rock along coastlines throughout the world results in the formation of specific types of landforms due to the minerals and rocks that are pulled from erosion into the sea and redeposition. The paper then explains that saltwater erosion takes two forms: impact erosion and erosion from the acidity in the saltwater. Limestone rocks are eroded due to the infiltration of water into the rocks, which breaks down the composition of rocks. Harder rocks are eroded through a process of impaction by the saltwater and the participles of rock and sand in the water. The paper also explains that, as these rocks erode, new formations result because the particles of erosion are placed in different locations along the coastline. Several illustrations, tables and figures are included with the paper.

Summary and Conclusion
From the Paper
"Along rocky coastlines where the action of waves has not occurred long enough to lower the coastline to the level of the sea a "wave cut beach and wave cut cliff develops."If a "subsequent uplift of the wave-cut beach occurs, it may be preserved above sea level and as marine terrace." Eventually the cliff will retreat due to processes of undercutting which result in mass-wasting processes. In the case of differential erosion sea caves result. The sea arch is formed from sea caves from opposite sides of a rocky headland meeting; however, when the sea arch weakens and collapses, the formation of a sea stack occurs."

Medical Staffing Management, 2005.
This paper argues that the situation of medical staff erosion is effecting patient care.
2,015 words (approx. 8.1 pages), 7 sources, MLA, $ 63.95
»
Click here to show/hide summary
Abstract
This paper explains that, with managed care systems, hospitals needed to compete for managed care contracts and gain clout with insurers for better reimbursement rates; therefore, administrators, who are usually not medically trained, save costs by downsizing the R.N. staff, resulting in less favorable patient outcomes. The author suggests that the simplest solution would be to abolish for-profit medical facilities and replace them with facilities judged on how well they spend all their income on patient care by providing the best possible medical care by doctors, nurses and nursing assistants. The paper concludes that, as long as the United States considers the right to make a handsome profit more important than the mandate to provide care for the sick, nothing will change.

Conclusion
From the Paper
"Hospitals may cross-train janitors and security guards to do nursing work. "Studies report that hospital nursing staffs, which once consisted of 85-95 percent registered nurses and only 5-15 percent aides, are now only 80, 70 sometimes 50 percent registered nurses and up to 50 percent aides." This sort of understaffing leads to errors. Sometimes those errors are R.N. errors, due to lack of time to consider all the ramifications of their own and their assistants' actions. For example, in one nursing care facility, an elderly man, called Mr. D by authors Baker and Cooper, was restrained, partially because of his behavior. However, he became agitated during a time when he was not under observation because, with too few assistants, an R.N. had to reassign some staff."

"Recruitment: Police Department Issues and the Los Angeles Community
Introduction
Recent stories in the Wall Street Journal have reflected the problems being faced in the public sector with particularly difficult jobs such as that of the police. One of the consequences of the O.J. Simpson trial -- coming as it did after the Rodney King incident and several other incidents in California and elsewhere -- has been a further erosion of public confidence in the police department, and this has been met by political leaders with attempts to gain more control over the police in order to reduce problems.

"Coastal Process of the Great Lakes
The Great Lakes are a series of giant tubs linked by rivers and smaller lakes (Gorrie, 1988, p. 20). The flow starts in Lake Superior (the largest and deepest of the chain) and then passes through the St. Mary's River to Lake Huron and Lake Michigan (Gorrie, 1988, p. 20). Because these two are joined by the broad Straits of Mackinac, they behave as a single sea (Gorrie, 1988, p. 20). Their waters are connected to Lake Erie by the St. Clair River, Lake St. Clair and the Detroit River; the Niagara River connects Lake Erie with Lake Ontario (Gorrie, 1988, p. 20). Eventually, much of the Great Lakes' water egresses to the Atlantic Ocean through the St. Lawrence River (Gorrie, 1988, p. 20). In recent years, this system of waterways has attained some of the highest water levels recorded this century (Cobb, 1987 ...."

Globalization and Sovereignty, 2007.
This paper argues that globalization must lead to some erosion of state sovereignty.
2,664 words (approx. 10.7 pages), 10 sources, MLA, $ 80.95
»

Abstract
The paper explores the subtle balance between globalization and sovereignty of the state. The paper supports the thesis that globalization continues to have an increasingly negative impact on the sovereign rights of individual nation states. The paper explains that globalization must result in a loss of sovereignty to some degree if unity is to be achieved. However, the paper points out that how much nations must give up largely depends on how different their laws are from international standards.
Outline:
Human Rights and Sovereignty
The Case of Feudalism and the Early History of the United States
A Matter of Degree
Conclusion
From the Paper
"The key roadblock to achieving complete globalization of the economy is the issue of sovereignty. Just as human rights issues pit the rights of the state against the rights of the individual, so does globalization pit the good of the world against the rights of individual nation states to determine their destiny. Until advances in communication led to rapid integration on a global level, the issue of state sovereignty was rather clear. Each state had the right to govern as it saw fit. Happenings within the borders had little impact on the world at large. That is not to say that conflicts did not occur, such as when it found that a certain group was treated unfairly, but when the basic rights of the group had been restored, the world once again backed out."

The Anoka Sandplain, 2002.
This paper discusses the geologic and environmental aspects of the Anoka Sandplain, a large sandy glacial outwash plain covering approximately 2200 square kilometers to the north of the Twin Cities Area in Minnesota.

Abstract
This paper explains the land use and management strategies of the Anoka Sandplain, which can be used for light industry such as sand and gravel mining, community districts such as business and residential areas and farming of alfalfa. The author believes that, when managing sandplains, we should take a cue from Mother Nature, which requires no outside inputs. The author feels that the best management is xeriscaping, which is landscaping that involves using plants that have minimal water requirements once established and require very little maintenance in general.
From the Paper
"Land management through erosion control is also important on the Residential and Commercial level. Practices in these areas include, the use of barriers preventing surface erosion from building sites to enter the natural environment. Also by using erosion blankets on loose soil, planting native grasses to hold soil, and by using retaining walls to hold critical slopes."
