This study approaches Maimonides' attitude towards miracles as a long-term process. The young Maimonides saw no room nor any need for miracles. Science provided a full and satisfactory explanation for events within a deterministic cosmos. However, as he matured, his doubts concerning the capacity of science to account for all events intensified; he increasingly realized that some features of the cosmos, or events in Jewish history, cannot be accounted for fully by any explanatory system. As his disbelief in the unlimited power of scientific explanation grew, he became more receptive to the possibility of miracles. For miracles are nothing other than events or features that, while not being totally at odds with science, cannot be fully accounted for in any theory. Maimonides' ultimate acceptance of miracles was, therefore, his ultimate acceptance of his own doubts and uncertainties. 相似文献
The WPPSI-R, WISC-R, and WPPSI were administered in a counterbalanced design to 72 children, between the ages of 5 years,
11 months and 6 years, 8 months, in order to determine their equivalence by testing the equality of means, variances, and
covariances based on scaled scores and IQs. The results indicated that the three scales were not equivalent with respect to
any of the IQs because they did not meet one or more of the criteria. The relative magnitudes of the mean IQs on the three
scales were in accord with the predicted order: highest IQs on WPPSI, next highest on WISC-R, and the lowest on WPPSI-R. Results
were discussed in the context of the secular inflation in IQs and the corresponding compensatory deflation built into the
normative data of the new versions. 相似文献
This study examines the influences of socialization and structural variables on relations among gender role orientations, interpersonal and ethical conflicts, and conflict handling styles. The data were collected from 134 female federal and provincial government supervisors and managers (Mage 40.1). Results of multivariate analyses of variance indicated that managers with high-instrumental traits are likely to indicate that they would use a dominating conflict handling style, and androgynous managers (high-expressive and high-instrumental traits) are more likely to indicate that they would use an integrating style. Managers did not report that they would use different conflict handling styles for ethical and interpersonal conflicts. Moreover, nonsignificant interaction effects indicated that the nature of the conflict did not moderate the gender role orientation and conflict handling style relationship.
The speed at which sit-to-stand (STS) motions are performed and the subsequent terminal constraint upon upright stance can present subjects with contradictory goals. Previous findings suggested that subjects might adopt a strategy of limiting the peak horizontal momentum of the center of mass (CM), and perhaps of body segments as well, regardless of the speed of ascent. The primary purpose of this study was to test the hypothesis that the limitation in CM momentum is related to the constraint on upright stance at the termination of the task. The secondary purpose was to describe the contribution of the shank, thigh, and upper body (head-arm-trunk) to the peak horizontal momentum of the CM under each test condition. Nine healthy adult males rose from a seated position under the following three conditions: (a) at natural speeds (natural STS); (b) as fast as possible (fast STS); and (c) as fast as possible, followed by falling forward while keeping the feet fixed and using the arms on a support bar to stop the fall (fast STS+fall). The results showed that the peak horizontal momentum of the CM did not change substantially from the natural to fast STS, but increased significantly from the fast STS to the fast STS+fall. These findings are consistent with the hypothesis that limiting peak horizontal momentum of the CM may reflect a movement control strategy related to maintaining equilibrium at the termination of the voluntary task of rising from a chair. The momentum profile of the upper body, but not of the thigh or shank, remained constant across all experimental conditions, suggesting that the motion of the upper body may be tightly controlled in STS, regardless of the altered constraint on balance. 相似文献
