Abstract
This paper presents a study that attempts to find out the effects of electricity conductors on the efficiency of data transmission of Bluetooth when they are close to the devices performing the data transmission. The paper also attempts to find out whether there is a significant difference between grounded and non-grounded electricity conductors. The paper relates that the conductor used in this study is aluminum foil and that the method applied is experimental research using the single factor experimental design. The data transmission is tested between a laptop and a cellular phone with Bluetooth functionalities. The results of the study reveal that electricity conductors have reduction effects on the efficiency of data transmission of Bluetooth because the data rate goes down during the experiment when the conductors are present around the devices. It is also discovered that grounded aluminum foil has even more reduction effect on the throughput of Bluetooth compared with the non-grounded one.

"Nowadays, the use of wireless technology in transmitting data from one device to another is becoming more and more prevalent. This phenomenon started in 1994, when Ericsson Mobile Communications, the global telecommunications company based in Sweden, initiated a study to investigate the feasibility of a low-power, low-cost radio interface between mobile phones and their accessories (Muller, 2001). The engineers at Ericson code named the new wireless technology Bluetooth to honor a 10th century Viking King in Denmark (Muller, 2001). At present, Bluetooth is one of the widely used wireless technologies by cellular phones in transmitting and receiving data. However, Bluetooth signal is disrupted by some external sources. One interfering factor is electricity conductor, which when hit by the Bluetooth frequency, is able to reflect or absorb radio waves. Since Bluetooth is a form of radio technology as mentioned by Thompson (2008), the present researcher came up with this study to determine the effects of electricity conductors on the efficiency of data transmission of Bluetooth. This would help the present researcher to integrate this study with his knowledge in data communications in order to come up with an efficient setup of a wireless computer network. To conduct this study, a computer, Bluetooth-enabled devices and electricity conductors were setup in an open-area environment where the data rate of Bluetooth would be recorded."

Abstract
This paper explains that both research and simple logic demonstrate that class size reduction (CSR) improves learning outcomes; however, some educators have looked at the data and concluded that CSR makes no difference. The author points out that teachers who have fewer students in their classes report benefits, which cannot be measured on the National Assessment of Educational Progress (NAEP) or any other tests, such as having the opportunity to get to know each child better and a reduction in discipline problems. The paper relates that there are some concerns about CSR because it is very expensive: CSR requires not only expensive new classrooms but more staff.
From the Paper
"Bracey conducted a thorough review of the current literature on the topic. The school district of Milwaukee, Wisconsin, conducted a study of their small class initiative, titled Project SAGE. Their results were thought provoking. They tried several approaches, including some classes with 15 students and one teacher, but other classes with 30 students and two teachers. Interestingly, both formats worked equally well. However, the population of students was overwhelmingly poor minority students. If this result continues over time and was not just a one-time aberration in the statistics, it could reduce one major cost of reducing classrooms, because the number of classrooms would be adequate."

Abstract
This paper explains that body burns are among the most destructive and damaging injuries because they have the potential to have long-standing physical, mental and financial consequences. The author points out that this proposed program is designed (1) to reduce the number of children suffering from body burns, (2) to teach children, school staff and parents the major causes of body burns and (3) to enable them to take necessary preventive measures. The paper reports that three kinds instructional sessions for children and parents will take place inside the classroom, on the playground and in the house.

"It is worth noting here that approximately 2 million Americans obtain remedial attention for body burns every year. Majority of the burns take place at their residence, at their workplace, or are caused during a road side accident. Approximately 50,000 and 70,000 American citizens are given treatment for body-burns each year as inpatients. Approximately 30% to 40% of this amount is children who are less than 15 years old. All body burns, both severe and minor, might source operational or aesthetic injury if they are left untreated and uncared for."

Abstract
This paper explains that factor analysis analyzes the patterns of relationship among several variables, with the aim of finding something about the character of the independent variables, which influence them, even though those independent variables, called factors, were not assessed directly. The paper explains that the results gotten by factor analysis are essentially more theoretical and provisional than is true when independent variables are spotted directly. The author stresses that, in order for the factor to be analyzed, the data must be bi-linear; this implies that the row entities and the column entities must be independent of each other.
From the Paper
"Factor analysis can handle over hundred variables at a time; recompense for random and meaningless mistakes, and unravel difficult interrelationships into their major and distinct reliabilities. But, factor analysis has disadvantages. It is mathematically problematic and requires varied and various relevant factors. Its technical terms include strange words like 'eigenvalues, rotate, simple structure, orthogonal, loadings, and communality'. Its product usually takes up a dozen or so pages in a given report, giving little space for a procedural foreword or clarification of terms."

Abstract
This paper explains that the connection between substance-abusing parents and child abuse has been studied at length; however, there is a lack of research into the correlation between social support services and the reduction of child abuse by these parents. The paper then proposes a research study that will evaluate if social support networks, such as 12-step programs, rehabilitation programs and related community-based social services, could lead to a reduction of child abuse and substance abuse. The paper explains that the population for this study is parents of African-American children between the ages of two and ten years old, who have a high incidents of child abuse and substance abuse.

"This is an area where family therapy can be especially facilitative. For families in which self-expression is considered a weakness, an empowerment approach can help define the family in terms of the unique forms, structures, and roles that clients are actually immersed in or are attempting to renegotiate, rather than in terms of an ideal unit. Clients should be supported in defining their families for themselves and then in using creative outreach strategies to actively involve the identified members in a variety of family sessions."

Abstract
A pretest-post-test, control group design was used to investigate effects of the "F/O Holding Technique". The subjects in the present study were 40 females and 40 males, who were randomly selected and contacted by the researcher to volunteer to participate. Subjects were pre-tested for existing job stress levels with the "Work Stress Inventory" stress test. They then received training in the "F/O Technique" and were instructed to continue with its use. Subjects were post-tested after three weeks. Results of the analysis of variance performed, confirmed the hypotheses that the "F/O Holding Technique" reduces hairdressers levels of job stress, and the effects were stable across gender. Additional study findings were that females tended to experience higher stress levels than males and that females tended to be more positive about the "F/O Holding Technique" than males. Implications of the study results are that the "F/O Holding Technique" is effective for stress reduction in male and female hairdressers.

From the Paper
"It should be noted that while there are several studies indicating that gender is associated with a differential experience of work stress; there are also studies that have found no effects for gender. For example, Hipps and Halpin (1993) investigated the amount of variance in burnout and job satisfaction of teachers and principles which could be accounted for by workplace stress; the authors also examined whether levels of stress were differentially associated with differences in sample subjects' ages, and gender."

Abstract
This paper looks at how sophisticated computer systems are a necessary cost that corporations are finding themselves faced with in order to maintain control and reliability of their computer systems. Without them accountants will be unable to appropriately balance and file reports. The paper discusses how, in order to reduce this, some corporations have put account managers in place to police their customers when checks are received and bills issued. This puts an additional level of checks and balances in place to try to eliminate inaccurate postings. The paper concludes that, although mistakes will occur even with data analysis systems and security protocols in place, the fact is that the best companies can hope for is to reduce inaccuracies.

From the Paper
"In today's market place data is being channeled into networks through user screens that are more than likely customers' computers. They submit their orders via their own computer systems while inadvertently place security responsibilities to others. With the Internet, online ordering is putting the customer in control of what he needs and when he needs it. This puts additional pressures on companies to not only protect the data that they currently have within the walls of their servers but to also maintain some degree or order in the process flow of data from a customer. While doing this it must also be realized that customer computers must be preserved from receiving corrupt or virus laden files from the company systems when they are attached to the corporate website or host providers.

Abstract
The purpose of this research is to study employee and customer's reaction to Lufthansa Airline's new service concept, based on its newly adopted cost reduction measures in order to remain competitive after the events of September 11 2001. This paper defines a problem statement and study design detailing such topics as the proposed literature review and the population, sample and sampling procedure.
From the Paper
"This study is of considerable significance for Lufthansa Airlines as it will help the organization redefine its business strategy in order to improve its corporate image and to compete effectively in existing tight market situations. The study will help the company in identifying the factors that directly affect customer's satisfaction and thus will facilitate in providing better quality service in future. As the current market conditions are not much favorable for the airline industry, especially in the US market, which itself is a major segment, airlines are required to keep an edge over their competitors. Therefore, it is necessary for Lufthansa to identify the reasons for dissatisfaction of customers as well as the crew members and to develop strategies to remove this discrepancy in its service. In this way it will successfully maintain its image, which it has developed over years and will ensure its long term success and profitability."

Abstract
This paper explains that Constraint-Induced Movement Therapy (CIMT), or Constraint-Induced Therapy, has become a promising choice for the treatment of patients with hemiparesis, especially after a brain insult such as a stroke; hemiparesis involves the partial impairment resulting from one side of the body being more affected than the other. The author points out that CIMT involves the constraint of the unaffected limb to stimulate use of the affected area by constraint and training to improve the ability of the affected limb. This paper relates that the proposed research will be a phenomenological, qualitative, assessment study and will be of use to patients and practicing occupational and physical therapists.

From the Paper
"An examination of the literature surrounding CIMT reveals that virtually all of the studies focus exclusively on measurements of improved performance. The only studies that acknowledge qualitative investigations do so in the context of recognizing the current lack of findings. In the context of the current literature on constraint-induced therapy it is important to recognize the lack of qualitative findings, and acknowledge the need for them as well. Therapy choices are only as effective as the patients they are used on. In the case of hemiparetic stroke patients, psychosocial impacts of therapies cannot be ignored."

Abstract
This report introduces the issues of fiscal balance in terms of problems faced by the Clinton administration and identifies alternative solutions. The paper also looks at existing literature on the subject and related issues, such as Clinton's financial advice to Japanese leaders and various interpretations of political occurrences of the time. The methodology of the report concentrates on financial data derived from existing literature, with an eye on the reduction of bias through a balanced report. Additionally, the paper analyzes data and discusses questions of how balance was achieved and provides recommendations for the future in terms of fiscal policy that can be derived from extant data.
From the Paper
"The reduction of deficit and fiscal balance was particularly highlighted in the later years of the Clinton administration, but it may have had roots in the beginning of the administration in terms of the background of the policies which went into effect regarding government spending and tax revenue. When Clinton came into office, he had ideas about overhauling spending which were soon put into practice so that spending could be increased and tax cuts for the wealthy would not be a big part of the program. There was significant dissonance between this vision, which also included extensive healthcare and welfare reform, and the vision of the mostly-Republican Congress which was in office for most of Clinton's years in office, and this also adds substantially to the
background of fiscal policy. For example, Clinton's programs were more likely to be slowed down in Congress by this type of system."
