This study concerned the immunological correlates of stress and work. Self reported stress, emotional state, ego-strength, and defensiveness were examined in relation to measures of cellular immunity (T-cell response to Con A and number of T4 and T8 cells) and humoral immunity (concentrations of immunoglobulins and complement components in plasma) in a group of 96 Norwegian female bank employees. The analyses showed that workload, the stress factor with the highest group mean, was associated with number of T-cells, while strain due to body posture during work was related to concentrations of IgM and C3. Further, depression was significantly correlated with IgM concentration and T-cell number, and anxiety with C3 concentration. T-cell activity was the immunological parameter most consistently associated with psychological well-being, showing positive correlations with defensiveness and ego-strength and negative correlations with anxiety and depression. In conclusion, T-cell number and concentrations of IgM and C3 were sensitive to both work-related stress experience and emotional distress. Coping abilities, indicated by the MMPI Ego-strength scale and emotional distress, were reflected in T-cell activity; insufficient coping was associated with low T-cell activity. 相似文献

The need for multilevel, comprehensive health promotion programmeshas become widely accepted, as has the importance of communityapproaches. However, many health promotion programmes focuson change at the individual level, no doubt partly due to thedifficulty of implementing all-inclusive health promotion. Thispaper discusses two strategies for guiding multilevel projects:multiple methods for community assessment and charting projectactivities by level of change (a possibility framework). Thesestrategies help ensure a multilevel focus and provide valuableinformation that can assist with the implementation of multilevelhealth promotion research projects in specific community contexts.Our primary purpose, therefore, is not to focus on theory orresearch findings. Rather, our goal is to make visible two strategiesthat have been helpful in one health promotion research projectin Victoria, British Columbia, Canada. 相似文献

A nationally representative sample of respondents estimated their fatality risks from four types of natural disasters, and indicated whether they favored governmental disaster relief. For all hazards, including auto accident risks, most respondents assessed their risks as being below average, with one-third assessing them as average. Individuals from high-risk states, or with experience with disasters, estimate risks higher, though by less than reasonable calculations require. Four-fifths of our respondents favor government relief for disaster victims, but only one-third do for victims in high-risk areas. Individuals who perceive themselves at higher risk are more supportive of government assistance. 相似文献

Certain issues that are being debated in psychology in a post-apartheid South Africa are discussed, namely the development of professional organizations, indigenous healing and psychology, the psychometric movement, and forms of methodological inquiry. It is argued that South African psychology is striving to become more appropriate to the majority of its peoples, whether it be on the professional or research fronts. There is a desire to develop indigenous epistemologies and not to become excessively reliant on Euro-American epistemological traditions. Psychology is struggling to make mental health resources available to all South Africans. 相似文献

Basic values, attitudes toward the homeless, and specific beliefs about a proposed facility were examined, along with the NIMBY (Not In My BackYard) phenomenon, to explore if, and to what degree, these factors affect community acceptance or rejection of a facility for the homeless. Previously designed Protestant ethic (PE) and Humanitarian-Egalitarian (HE) scales were used to measure two basic values (Katz & Hass, 1988). Scales to measure attitudes toward the homeless and beliefs about a planned facility were developed. As predicted, values, attitudes, and beliefs correlated with each other and were related to plan acceptance, so that HE, pro-homeless attitudes, and positive beliefs about the plan were positively related to acceptance, and PE, anti-homeless attitudes, and negative beliefs about the plan were positively related to rejection. Also as predicted, four proximity measures were all related to acceptance of the plan. 相似文献

Developing a fair and widely accepted income definition presents one of the greatest challenges to tax reform. To arrive at a definition separate from the federal tax code, we surveyed 1200 Latter‐day Saints about their practice of tithing. Tithing is similar to a flat tax with no deductions, where individuals voluntarily contribute 10% of self‐defined income to the church. The results of our survey indicate that most respondents operate on a cash realization basis, which excludes savings and does not allow any deductions. Respondents' income concepts generally do not coincide with current tax laws or economists' views of comprehensive income. 相似文献

Sustainability is usually defined as a requirement of each generation to manage its stocks of man-made and natural capital
such that the utility that it ensures itself can be shared by all future generations. Here we extend this definition to the
case where capital management does not have deterministic consequences. A characterization is offered where the sustainability
of one generation's behavior can be determined by comparing its utility with the utility of the succeeding generation, provided
that the latter behaves in a sustainable manner. The properties of the definition are investigated and illustrated.
