The study examined psychosocial work-conditions and physiological reactions among thirty-six police inspectors (median age 45 years, 81% males) who participated in a reorganization. At this time, subjects were threatened by unemployment and had to reapply for their positions in a new police district. Data were collected during the reorganization and at three years follow-up, by means of questionnaires (Stress Profile) and blood samples. The blood samples were used to determine serum levels of gammaglutamyltransferase (GGT), glucose, lipids, prolactin, testosterone and cortisol. The results show a positive association betweenworry about employment and symptoms ofburnout during the reorganization. Mean scores for the Stress Profile sub-scalesworry about employment (p<.01) andwork-load (p<.05) decreased between measurements but an impairment inrelationships with management was noticed (p<.05). No significant changes were observed in terms of self-rated health complaints. Significant decreases in total cholesterol (p<.0001), LDL-cholesterol (p<.0001), LDL/HDL-ratio (p<.01), prolactin (p<.0001), as well as increases in testosterone (p<.01) and cortisol (p<.001) were observed for the whole sample. Glucose decreased with marginal significance (<.07). Controlling for age and gender, multivariate regression analyses showed that subjects who reported deteriorations insatisfaction with work manifested the most modest decreases in prolactin (p<.05). Also, the decrease in glucose was larger for subjects who experienced impairments in,satisfaction with work (p<.05), information (p<.05), task-oriented leadership, (p<.05), andrespect and dignity (p<.05). Subjects who perceived deteriorations in theethical and moral standards of the organization increased their cortisol level to a lower degree than their counterparts (p<.05). Favorable changes in employment status and psychosocial work environment seem to be related to improved physiological functioning.  相似文献

A total of 119 clinically stable patients with symptomatic congestive heart failure (34 females, 85 males) were recruited from an outpatient hospital practice to explore the role of objective health indicators and neuroticism in subjective health (physical limitations) and psychological well-being. Patients were grouped according to the New York Heart Association functional class criteria (NYHA: indicator of functional status) and proatrial natriuretic factor (proANF), a cardiac hormone that maintains normal fluid balance and vascular resistance. Scores on these two objective indicators of disease severity were generally unrelated to psychological measures, whereas neuroticism scores (EPQ-N) were significantly correlated with indicators of subjective health (perceived disease-related physical limitations) and psychological well-being (depression, general life-satisfaction). Significant interactions between proANF and neuroticism appear due to low physical limitation score among subjects with elevated level of proANF and low scores on neuroticism. High physical limitation was reported by subjects with high level of proANF as well as high scores on neuroticism. Moreover, a marginal significant interaction between NYHA and EPQ-N scores in relation to severity of depression was detected by analyses from two-way ANOVA. Gender differences were due to higher proANF scores in males than females, whereas females scored higher than males on EPQ-N, perceived physical limitation and depression. Results from path analyses supported an indirect effect of neuroticism via perceived physical limitation for males. Possible mechanisms involved in these relations are discussed.  相似文献

Conclusion Unlike the more commonly discussed paradoxes of deontic logic, the revenger's paradox is present not only in strong logics such as SDL, but also in much weaker logics that have been constructed to avoid the paradoxes of SDL. The paradox shows that any deontic logic with intersubstitutivity makes counter-intuitive truth assignments to some deontic expressions.However, the revenger's paradox does not pose as serious a problem as does Ross's paradox to the logics in which it occurs. A deontic logic in which Ross's paradox does not arise is preferable to one in which it does arise, even if the latter is subject to the revenger's paradox.  相似文献

In a reviewed series of spontaneous and learning-set studies of adults and children, we have monitored active-touch overt attending during concept learning. Adults solved the problems even if they attended to four dimensions in the same trial; however, young children failed when attending so broadly but solved when attending to a single dimension. In the present training study, 18 6-year-olds solved all problems when restricted to attend to anly one dimension. After a special pretraining program proceeding through the subprocesses of stimulus familiarization, discrimination, labeling, “attentional broadening,” and memorization, 13 of the children managed to attend to all four dimensions in one trial and solve faster than adults. Findings suggest a developmental hypothesis that learning grows with spontaneous “tailoring” of attention to memory capacity.  相似文献

Despite continually increasing evidence for the effectiveness of psychodynamic psychotherapy in general, the empirical status of long-term psychodynamic psychotherapy (LTPP) remains controversial. Convincing outcome studies of LTPP were lacking for a long time. This article gives an overview of available systematic reviews addressing the evidence for LTPP. The findings suggest that LTPP can yield large and stable effects across a variety of diagnoses and particularly in complex mental disorders, which even tend to increase after termination of treatment. In comparison to other shorter or less intensive methods of psychotherapy, LTPP has proven to be significantly superior with respect to most outcome domains. First economic analyses suggest that LTPP may be cost-effective in the long run. The comparison of randomized controlled with observational studies revealed no significant differences in outcome; however, the evidence for LTPP is frequently challenged by proponents of other therapeutic approaches or scientific orientations. The criticisms were repeatedly answered and none of the concerns raised by critics identified an issue that would have affected the overall conclusions of the available reviews. Nevertheless, further studies are urgently required to broaden the evidence base for LTPP in order to allow more refined analyses addressing the effects of specific forms of LTPP both in specific disorders and in comparison to specific forms of alternative therapies.  相似文献

An experiment, in the standard scientific sense of the term, is a procedure in which some object of study is subjected to interventions (manipulations) that aim at obtaining a predictable outcome or at least predictable aspects of the outcome. The distinction between an experiment and a non-experimental observation is important since they are tailored to different epistemic needs. Experimentation has its origin in pre-scientific technological experiments that were undertaken in order to find the best technological means to achieve chosen ends. Important parts of the methodological arsenal of modern experimental science can be traced back to this pre-scientific, technological tradition. It is claimed that experimentation involves a unique combination of acting and observing, a combination whose unique epistemological properties have not yet been fully clarified.  相似文献

A commonality in the economics of happiness literature is that absolute income matters more for the subjective wellbeing of people at low income levels. In this article, we use a large sample of people in rural areas of developing countries with relatively low income levels to test whether subjective wellbeing an increasing function of absolute income in our sample, and to analyze the existence of adaptation and social comparison effects on subjective wellbeing. Our sample includes 6,973 rural households in 23 countries throughout Asia, Africa, and Latin America. The average total income per adult equivalent in our sample was US$ 1555, whereas levels of subjective wellbeing resembled levels found in previous research using cross-country data. We find that, despite low levels of absolute income, levels of subjective wellbeing of our respondents resemble levels found in previous research using cross-country data. We also find remarkable similarities in many of the determinants of subjective wellbeing previously tested. Our data show that absolute income covariates with subjective wellbeing, but—as for richer samples—the magnitude of the association is lower once we control for adaptation and social comparison. Finally, our results suggest that social comparison has a stronger effect than adaptation in explaining the subjective wellbeing of our sample. Our findings highlight the importance of adaptation and social comparison even at low levels of absolute income.  相似文献
