浅析我国西部地区的三次经济大开发 总被引:1,自引:0,他引:1
抗日战争和“三线”建设是现代西部进行的以工业开发为主要内容的两个大开发时期 ,对于改变中国工业布局集中分布在沿海和长江中下游地区的极不合理的状况虽有重要意义 ,但两次开发从决策、规划到实施均是毁多于益 ,尤以成本效益方面为甚。而第三次工业西进与前两次相比具有完全不同的动因和背景 ,是我国经济发展客观规律的内在要求 ,特别是西部地区自身也具备了经济大发展的各种条件。 相似文献

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

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.
