A modified version of Caplan's Job Stress Questionnaire (JSQ) was administered to 169 male and 56 female entrepreneurs. Entrepreneurs were found to have higher levels of stress associated with workload than with role ambiguity and underutilization of skills. Compared to scores reported previously for various occupational categories, the entrepreneurs scored significantly higher than did white collar, blue collar, and professional groups on the workload scale and significantly lower on scales measuring role ambiguity and under-utilization of skills. These results may be due to the nature of entrepreneurial activity, which is often characterized by heavy workloads, long hours, and a self-established role in the organization. Additionally, the factorial composition of the JSQ and its internal consistency were examined. Evidence of convergent and discriminant validity at the item and subscale level confirmed the a priori dimensions of the JSQ, although the internal consistency of the scales were low to moderate. The need for various improvements in the measurement of occupational stress is briefly discussed.  相似文献

Williams and Best's (1982, 1990a) cross-culturalgender stereotype data from 25 countries, previouslyanalyzed in terms of affective meanings, ego states, andpsychological needs, were re-analyzed in terms of the Five Factor Model (FFM) of personality.In each country, participants were approximately 100university students, equally divided by gender. Withresults averaged across all countries, it was found that the pancultural male stereotype was higherthan the pancultural female stereotype on Extraversion,Conscientiousness, Emotional Stability, and Openness toExperience while the pancultural female stereotype was higher on Agreeableness. Re-analysis of thestereotype data from Japan and Pakistan, which had beenfound relatively atypical in previous analyses, revealedFFM profiles generally similar to the pancultural profiles. The evaluative nature of each factoris discussed and related to the stereotypes associalization models.  相似文献

The relationship of characteristics of the social environment to the adaptation of adolescents from high-risk predisposing environments was examined. Specifically, the degree to which adolescents' perceptions of various dimensions of their family and school environment as well as sources of social support related to differential levels of personal well-being and academic adjustment was explored. Multiple regression analyses revealed differences in the salience of the dimensions of the social environment as a function of the particular sphere of functioning under consideration. Implications of the findings for developing a model for understanding the relative vulnerability of individuals at risk as well as of the design of preventive interventions are discussed.  相似文献

The significant growth in the clinical literature on early childhood psychopathologysince the publication of the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Zero to Three–Revised (DC:0–3R; ZERO TO THREE) in 2005 necessitated substantial revisions to the manual, which resulted in the publication of the DC:0–5: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Zero to Five (ZERO TO THREE) in 2016. In addition to the decision to extend the early childhood diagnoses to include children through age 5 years, significant revisions were made to many diagnoses, and new diagnostic categories were added such as the Relationship Specific Disorder of Infancy/Early Childhood. Other additions, such as guidance for the development of a Cultural Formulation for the young child and his or her family and the inclusion of functional impairment criteria also contribute to making the DC: 0–5a substantially more comprehensive and robust diagnostic framework than its predecessor.  相似文献

There is a common assumption about pictures, that seeing them produces in us something like the same effects as seeing the things they depict. This assumption lies behind much empirical research into vision, where experiments often expose subjects to pictures of things in order to investigate the processes involved in cognizing those things themselves. Can philosophy provide any justification for this assumption? I examine this issue in the context of Flint Schier's account of pictorial representation. Schier attempts to infer the assumption from what he takes to be the fundamental facts about picturing. I argue that there is no plausible form of Schier's basic claims from which the assumption can be inferred. I then reject a second argument, that by appealing to the assumption Schier could explain why it is impossible to depict a particular without depicting it as having certain properties. I conclude that those sympathetic to the assumption need to articulate and defend some version of it suited to their needs.  相似文献

Two experiments examined sequential and simultaneous conditioned inhibition in an autoshaping preparation. In Experiment 1, a 5-sec coloured keylight (A) was reinforced when presented alone. However, reinforcement was withheld from trials on which A was preceded by one grid pattern or presented simultaneously with another pattern. A third (control) pattern was presented separately without reinforcement. Inhibition developed most strongly to the grid pattern presented simultaneously with A. However, a transfer test with another excitatory coloured keylight found both inhibitors to be equally strong whether they were tested in simultaneous or in sequential compound. Experiment 2 compared grid patterns that consistently had sequential or simultaneous relations to the excitor with one that was sometimes presented in sequential and sometimes in simultaneous compound. The mixed treatment pattern showed levels of inhibition like the simultaneous or sequential pattern, depending on the temporal relation it bore to A on a particular trial. These results suggest that sequential and simultaneous relations between inhibitors and excitors yield similar amounts of inhibition. However, that inhibition is better exhibited when tested in simultaneous compound with the excitor.  相似文献
