Abstract
This paper contains information about the construction and parts of a common laser. The paper also provides a detailed description of how the laser works and discusses some of the dangers and negative aspects of lasers. The paper also covers the different uses of the laser such as leisure use, business use, and home use. Lastly, future possibilities for the laser and how it can still benefit society with uses not yet explored are discussed.
From the Paper
" Lasers are high intensity beams of light emitted from a unit consisting of a flash bulb, a ruby, and opposing mirrors. Theodore Maiman first introduced these extremely strong light beams to the world in 1960. The beam emitted by the laser is very intense and can be damaging or harmful. Although harmful, lasers are also very useful tools for a wide array of tasks. Lasers are used for everything from eye surgery to leveling a ceiling. Lasers are an innovation that has withstood the test of time with people finding new and creative uses for this spectacular invention."

Introduction
Literature Review
Conclusion
From the Paper
"While lasers have become more widespread in the past decade, it did take the FDA a certain amount of time to approve their use for more than soft-tissue procedures. "For soft tissue surgery, lots of patients report less postoperative pain. There are sealed off nerve endings, so recovery is less painful," according to Marilyn Miller, D.M.D., co-director of the Princeton Dental Resource Center in Princeton, N.J. (Quoted by Lewis 1995 15+). Her observation, however, is that despite the gains in reduced pain, reduced fear and reduction in some of the immediate results of dental procedures, such as swelling, healing time may actually increase slightly because the laser seals off blood vessels that would otherwise help healing by delivering blood to the tissues more rapidly (Lewis 1995 15+)."

Abstract
This paper attempts to provide a brief analysis of September 11, 2002 in the light of thick description. It uses a semiotic approach to cultural analysis to facilitate a better understanding of cultural differences and their impact on the world today.
From the Paper
"Since, the ?cultural theory is not a master of itself, it is not heavily predictive or a mere post facto? (Geertz, p. 26) therefore the thick description vehemently opposes considering the theoretical context of the cultural similarities and dissimilarities. Thus as an ethnographer, I have applied thick description to this new interpretive political event of September 11, 2002 thereby basically focusing on the symbolic signs either dormant or apparent in the process of the review and research as well as interpretation. ?The aim is to draw large conclusions from small but very densely textured texts; to support broad assertions about the role of culture in the construction of collective life? (Geertz, p. 28)."

Job Descriptions, 2002.
Explains why job descriptions are such important tools for human resource managers.
2,034 words (approx. 8.1 pages), 10 sources, MLA, $ 64.95
»
Click here to show/hide summary
Abstract
The job description is a concise, complete, organized outline and description of the tasks, priorities and time allocations of a particular position, often accompanied by designation of the competencies and skills required by the work. The paper shows that rather than merely describing the manner in which a job is being done at the moment, it should describe the manner in which the job should be done. Job descriptions can be created prior to a position being activated or can be produced for existing jobs. The paper shows that in their most complete forms, job descriptions are one of the most valuable tools Human Resource (HR) managers possess and, if properly executed, published, and comprehended, can be of equal value to managers and employees throughout the organization.
From the Paper
"Job analysis typically produces a great deal of information--all of which is not directly applicable to the job description. But since the purpose of the description is to provide a basic source of information, on which employees, supervisors, senior management, and the HR specialist can draw, the larger knowledge base produced by job analysis is entirely desirable. As Siegel notes, as many as 14 different types of data might be assembled in job analyses, including government-mandated licensing or training, professional standards, job responsibilities, environmental information, identification of outputs (products and services), specific machinery and equipment employed, work performance standards, physical job demands, elemental motions, activities, trait requirements (knowledge, skills, abilities and personal attributes), and examples of outstanding or inferior performance in the position (Siegel 12)."

Laser Eye Surgery, 2002.
Discusses the use of laser surgery and its effectivness for vision correction.
1,400 words (approx. 5.6 pages), 5 sources, $ 53.95
»
Click here to show/hide summary
Abstract
Prior to the advent of laser vision correction the only hope for sufferers of poor eyesight was wearing glasses or contact lenses. The reason for this is that vision problems are the result of flaws in the surface and/or shape of the lens. Correcting such flaws was completely out of the realm of possibility until laser surgery was invented. Since that time, the use of lasers in surgical application for vision correction has increased and improved to the point where it is now one of the most common forms of out-patient surgery. It is the purpose of this paper to examine the application and effectiveness of laser vision correction surgery.

Abstract
This paper explains that Laser-Assisted in Situ Keratomileusis (LASIK) and recent variations thereof are the preferred methods for suitable candidates, while Laser Epithelial Keratomileusis (LASEK) is the option for patients whose corneal thickness is insufficient for LASIK procedures. The author points out that the ideal prospective patients are older than eighteen years of age, since their eyes are no longer growing and changing in shape, and the problems for which they seek treatment fall within the category of pathology for which LASIK procedures are most appropriate, such as myopia, hyperopia, and astigmatism. The paper cautions that laser eye surgery is a lucrative business, and the development of the technology has resulted in a virtual explosion of discount laser eye surgery centers throughout the country.

From the Paper
"Ideal candidates do not suffer from eye disease or from any other disease or autoimmune disorders that might delay or retard surgical healing or resistance from infection. Similarly, ideal candidates for laser surgery are not taking any medications that increase bleeding or edema. Finally, it is highly desirable that prospective patients fully understand the nature of their eye problems and the degree to which those issues are reversible through laser surgery, as well as the likelihood and nature of post-operative recuperative delays and residual vision problems and limitations."

"The job description is a concise, complete, organized outline and description of the tasks, priorities, and time allocations of a particular position, often accompanied by designation of the competencies and skills required by the work. But, rather than merely describing the manner in which a job is being done at the moment, it should describe the manner in which the job should be done. Job descriptions can be created prior to a position being activated or can be produced for existing jobs (often with a combination of incumbent self-report, supervisor input, and administrative contributions and control). They can be the result of extensive job analysis or they may be less formally prepared. But, in their most complete forms, job descriptions are one of the most valuable tools Human Resource (HR) managers possess and, if properly executed, published, and..."

Abstract
This paper takes a look at the method of descriptive analysis and assessment. According to the paper, descriptive analysis can provide useful solutions in terms of individual behavior analysis and observation. There are various descriptive analysis techniques, which this paper reviews and discusses.
From the Paper
"As such, related to observance and the difficulties that occur in such situations, Kazdin brings into question and discusses the nature of the observation, in terms of realism, accuracy and convention ((Kazdin, 1977)). Indeed, descriptive analysis relies on one of the essential tools: observation. If we look at the descriptive assessment as an evaluation of the "how", observing and recording how this "how" will determine the eventual outcome of the analysis. The problem that Kazdin is debating is the existence of a multiple number of observers and, more importantly, the complexity deriving from having different observations and from checking their reliability. The accuracy of the observation is one of the main issues to be discussed when referring to the challenges and implementation of descriptive analysis. "

Laser Propulsion Systems, 2002.
An overview and scientific explanation of the different methods of laser propulsion.
1,314 words (approx. 5.3 pages), 5 sources, MLA, $ 44.95
»

Abstract
In today?s world, almost all forms of transportation rely on some form of an onboard device as a means of propulsion. This paper discusses the various types of laser propulsion (ALP, SLP, CW, RP, LSD, LSC, etc.) currently available and their development in the context of modern technology. It also addresses the scientific aspects of laser propulsion, with accompanying explanations of physical phenomena supporting such devices. Examples are illustrated with pictures and diagrams.
From the Paper
"Due to the plasma basis of this method of propulsion, a liquid or gas is mandated as the type of fuel to be used. Early tests utilized hydrogen and nitrogen as reactant gases and liquids, however it was soon found that plain air worked nearly as well4. As a result, air-breathing lightcrafts quickly became the standard in LP research, for any reactive faults of air in comparison with other gases are dismissible when the lacking cost, and natural abundance of air are taken into account."

Descriptive Statistics, 2006.
A discussion regarding the use of descriptive statistics and various common errors.
675 words (approx. 2.7 pages), 3 sources, $ 26.95
»
Click here to show/hide summary
Abstract
This document discusses a series of descriptive statistics questions. These range from the four types of errors related to measurement as well as response and non-response related errors. Finally, the paper makes several statistical calculations in order to establish the efficacy and practicality of descriptive statistics. Specifically, these problems rectify issues of accuracy and estimation.
From the Paper
"The four major sources of measurement error are respondent, situation, measurer, and instrument. Respondent errors might occur through respondent misinterpretation of a given question or, in the case of a written survey or questionnaire, actual response error (Lomax, 2001, pp.29-31). A situational error would occur when, for example, a political survey for a given district was being taken in another district. Measurer originated errors can occur in several ways from construction and design of the actual study to poor selection of participants as well as misinterpretation of study results or actual errors in compilation of results. Instrument, such as surveys or questionnaires, often occur because they question or respond to something other than what is being tested or researched. "
