The passage in the USA of the Americans with Disabilities Act (ADA) has mandated the private sector to provide a sweeping variety of accommodations to individuals with disabilities. Objections to ADA focused on costs in an era of scarcity. These assumptions have been presented with insufficient information about the actual needs of individuals with disabilities. This study is a needs assessment of employees with disabilities at a major university setting. In-depth interviews were conducted with a small number of individuals who described their work situations and accommodations. Findings challenge prevailing assumptions. Costs are often not large, many accommodations are simple, and much depends on the match between a person's disability and job duties. Additionally, informational needs, psychological concerns and the existing social climate provide a more balanced picture of the lives of these employees.  相似文献

This study attempted to identify the primary activities performed by R&D managers at different supervisory levels, and the cognitive and interpersonal ability requirements that underlie these activities. A task inventory containing 244 managerial tasks was completed by 117 R&D managers in nine organizations. The 48 tasks which managers rated as having spent the most time were factor analyzed, resulting in the identification of three primary activities: project management, personnel supervision, and strategic planning. Furthermore, these activities varied with supervisory level, with R&D managers performing a wider range of these activities with the progression from first-line to upper-level management.Thirty R&D managers later rated the degree to which 19 cognitive and interpersonal abilities were required for performing these primary activities. Strategic planning was rated as requiring significantly higher levels of oral expression, logical reasoning, originality, fluency of ideas, oral defense, and resistance to premature judgement than was required for the other two primary activities. Personnel supervision required a higher level of social sensitivity than was required for the other two activities. Project management required high levels of information ordering, oral fact- finding ability, problem sensitivity, and oral and written comprehension. Implications of the findings for understanding R&D managerial performance and personnel staffing functions are discussed.  相似文献

1. Research shows that many emergency workers are affected physically and emotionally by critical incident stress. 2. Debriefings conducted by trained team members are an effective method to mitigate the impact of critical incident stress. A debriefing is a structured, time-limited group intervention. 3. Cooperation among community agencies is essential for the development and effective functioning of a critical incident stress debriefing team. 4. Several teams in Illinois have organized to form a Critical Incident Stress Debriefing Network. The Illinois network is part of an international organization composed of critical incident stress debriefing providers.  相似文献

Sex differences in expressiveness are well documented, but the reasons for and correlates of these important differences are not well studied. A comprehensive set of emotion-relevant personality measures was administered to 40 female and 39 male undergraduate participants, who were also videotaped in three situations: engaging in natural social interaction, describing a past emotional experience, and posing various emotions. Videotapes were judged by sets of naive observers as to emotion communicated and overall impression. Expressive females, who appeared friendly and dominant in social interaction, were found to have a hostile/aggressive personality (but this was not true of males). Expressive females also tended to look angry/disgusted when describing happy and sad experiences. The findings suggest that nonverbally skilled, charismatic women (but not men) may often possess a dominant/aggressive but self-controlled personality, in a new twist on the theory that sex differences in expressiveness result in part from the oppression of women in society.This research was supported in part by an intramural research grant from University of California, Riverside.  相似文献

The unstable, even precarious labor conditions of many frontline service jobs in the United States should render them undesirable to upwardly mobile young workers. Yet for many, these types of jobs complement, rather than infringe upon, their broader lifestyles. Drawing on six years of ethnographic research in upscale Los Angeles restaurants, I show how front-of-the-house service workers navigate portfolio lives—sustained though shifting arrangements of labor and leisure that blur the boundaries between the two. I describe how these workers, who are mostly young, white, and college educated, leverage both personal resources and workplace structures to weave their restaurant jobs into their larger webs of activities. I close by discussing how the concept of portfolio lives extends theories of boundaryless work careers to the urban service economy, though these dynamic assemblages remain subject to class and race inequalities.

A methodology is suggested for the estimation of the mass density and the cumulative ground deposition of a nonvolatile, nonneutrally buoyant, air pollutant (liquid or solid) released from a polluted column (following an explosion caused during routine operation in, e.g., the chemical industry or due to any kind of hostile act) and deposited on the ground via gravitational settling. In many cases, the deposited mass due to gravitational settling constitutes a significant fraction of the original inventory released from the source. Implementation of the methodology in preliminary risk assessments can serve as an efficient tool for emergency planning for both immediate and long‐term measures such as evacuation and decontamination. The methodology considers, inter alia, an estimation of the critical particle diameter, particle size, and mass distributions along the polluted column. This methodology was developed to apply in rural regions since proper application of relevant meteorological input data can be accomplished mainly for such areas.  相似文献
