A population of 72 bifocal wearers was studied to determine the relationship between VDT (video display terminal) placement for those who reported musculoskeletal pain and those who did not. The mean hours worked was 50.4 minutes (p=0.003) greater for those who reported head/neck pain versus those who did not and 48.6 minutes (p=0.004) greater for those who reported shoulder/arm pain that those who did not. There was no statistically significant difference between the means of monitor height, distance, or angle for those who reported pain symptoms versus those who did not. This study indicates that, self reported pain symptoms are correlated with hours of VDT work and that there appears to be a threshold at approximately five hours for pain symptoms among bifocal wearers. No such correlation can be made for monitor placement 相似文献

OBJECTIVE: The primary objectives of this study were to identify sources of meaning for individuals within the context of a work environment, and to compare varied sources of meaning for individuals with high and low work satisfaction levels. METHOD: Participants were chosen based on satisfaction levels in employment, full-time employment status within an organization for at least one year, and diversity in the work setting. Data were gathered through a series of interviews and observations of the participants' workplaces. A comparative analysis of transcribed interviews was conducted by the researchers and with an expert occupational therapy faculty panel. From these analyses, the researchers developed work narratives for a mechanical engineer, a high school teacher, an employee of mechanical services, and a career service counselor. RESULTS: Emerging themes from the work narratives indicated that the various meanings employees found in work had an effect on their perceived levels of job satisfaction. Participants conveyed that organization identification, financial benefits, independent decision-making, reciprocal respect, opportunities for creativity, and maintaining significant relationships outside of work enhanced meaning and satisfaction. CONCLUSIONS: The worker role is a significant source of an individual's identity, meaning, and satisfaction in life. Professionals in various fields can work with employers to develop meaningful work environments for increased job satisfaction, greater motivation for work, increased productivity, and decreased employee turnover. 相似文献

This article investigates the theoretical and empirical properties of a true cost-of-living index under conditions of changing preferences. A family of true indexes is defined based on the notion of the current utility function. A particular index, based on the previous period's utility level, is then defined. Given this definition, a true cost-of-living index is computed based on a quadratic expenditure system estimated with quarterly data from 1960–1981. For empirical purposes, changes in preferences are represented by the linear habit formation hypothesis. This index is then compared with Paasche and Laspeyres indexes. The true cost-of-living index grows somewhat faster than either the Paasche or Laspeyres index. It also displays considerably more variability. 相似文献

The subject of Integrated Management Systems in terms of quality, environmental and occupational health and safety management has become of increasing interest to researchers and business alike during the last 3 years or so. This paper focuses on a review of the various models of integration found in the academic literature and also those advocated by the standards bodies, such as the British Standards Institution and the International Organization for Standardization. A number of writers advocate alignment of ISO 9001 and ISO 14001 and present models to facilitate this; however, integration into a single standard is, in general, not favoured. Various models have been developed to overcome these difficulties, but the authors believe that none is completely satisfactory. It is considered that a model of integration based on the EFQM Model for Business Excellence will allow the limitation of the standards to be overcome and the total systems approach to integration to be facilitated. 相似文献

HIV and drug use are higher among prisoners than the general US population. This study examines drug dependency/use and differences between prisoners who volunteered for HIV testing and those who did not in a less densely populated state. It was hypothesized that prisoners who volunteered for an HIV test were engaged in more drug use and other risky behaviors than those who did not. Survey data were collected from 600 randomly selected inmates (567 males and 33 females) from 15 state prisons. Subjects were male (95%), white (63%), never married (43%), and 44% volunteered for an HIV test since entering prison. Ninety-two percent of inmates met DSM criteria for drug dependence in their lifetime. Those who volunteered for HIV testing were 2.6 times more likely to ever have used PCP; 1.5 times more likely to ever have used cocaine; 1.4 times more likely to ever have had a problem with drugs; 1.3 times more likely to have used opiates, and 1.6 times more likely to report having been sexually or physically abused. Implications for interventions are discussed. 相似文献

Late in the 1998 hurricane season, Central America was slammed by a devastating hurricane. Honduras, Nicaragua, El Salvador, Guatemala, and Belize were greatly impacted by Hurricane Mitch, one of the deadliest storms to affect the region in the past 200 years. The economies of each of these countries were badly affected. In the case of Honduras — at the time the fourth‐poorest country in Latin America — its president suggested that 50 years of progress had been wiped out by the floods and mudslides associated with this relatively short‐lived storm system. Humanitarian assistance poured into the region in the first months following the disaster. As of mid‐2000, various national, bilateral, international, and nongovernmental programs were in progress or on the drawing board for recovery, reconstruction, and renewed development of the worst affected countries. Using Honduras as a case study, some of the ethical issues that abound in the decisions of whom to help, when, and how to help them in the wake of such an extreme climate‐related human tragedy are examined. Should development assistance be focused on those who have been directly and adversely affected by this storm, or should the emphasis be on reducing the risk of exposure by future generations to such disasters? Is there yet another approach that seeks to protect future generations from similar harm while at the same time assisting present‐day victims to get through their hardships? 相似文献

The relationship between spending on education and equal opportunity has been a subject of debate for several decades. This study aims to shed light on this debate by examining correlations between the distribution of Blue Ribbon awards to Indiana middle and high schools and per pupil expenditure. Based on criteria that include curricula, instruction, school climate, leadership, community support, goal setting and attainment, success with all students, skill development, and character education, Blue Ribbon School awards are a recognition of outstanding achievement given by the federal government. Using total federal, state, and local expenditures as the basis for comparison, we found that the federal government did not select more wealthy schools than poor schools for the Indiana Blue Ribbon School awards. However, there was a large difference in the expenditures per pupil in the Indiana districts with Blue Ribbon schools vs. the 30 randomly selected Indiana districts without Blue Ribbon schools. Total local sources were significantly greater in Blue Ribbon school districts than in non-Blue Ribbon school districts. A discussion of items related to the power, prestige, and wealth of the award-winning schools is included. 相似文献

Forty children with prelingual, profound deafness who received the Nucleus multichannel cochlear implant between the ages of 2 and 13 years participated in this study. The children had an average of 63.3 months (SD=24 months) of experience with their cochlear implants. A majority of the children used simultaneous communication and attended public-school programs at the time of testing. Reading achievement was assessed using the Paragraph Comprehension subtest of the Woodcock Reading Mastery Test-Revised, Form G (1987). This study compared the reading-achievement levels of this group of cochlear-implant users with the results of previous studies of children with profound hearing losses who did not have the benefit of cochlear implants. Results indicated that nearly one half of the children in this study were reading at or within 8 months of their grade level. The reading-grade quotient of .74 was calculated based upon the slope of the regression line for the plot of years in school and reading grade-level achieved. This finding indicates that using a cochlear implant has a positive effect on reading achievement level. 相似文献

This article presents a reconceptualization of individual religiosity based largely on a structural variant of symbolic interactionism and incorporating "religious salience," the importance of religion to an individual. The reconceptualization links the Glock-Stark multidimensional conceptualization of religiosity to the concept of role-identity as used by Stryker and other identity theorists. Two components of religiosity are proposed: (1) religious norm adherence , the quality of one's religious role performance (the focus of the Glock-Stark model); and (2) religious identity salience , the importance of a person's religious identity relative to that person's other identities. Procedures for measuring religious identity salience are considered. It is proposed, based on structural symbolic interactionism and cognitive behaviorism, that the degree and dimensional structure of norm adherence are strongly influenced by identity salience, contingent on costs and rewards associated with each normative behavior. 相似文献
