The current study examined cardiovascular risk factors and carotid atherosclerosis in 362 women (ages 42-50 years) who were working in clerical, blue-collar, or white-collar jobs or who were not employed. Risk factors were measured premenopausally and ultrasound measures of carotid atherosclerosis were obtained approximately 11 years later. Clerical and blue-collar workers had more atherogenic profiles on physical, behavioral, and psychosocial risk factors when compared with white-collar and nonemployed women. Clerical workers had greater carotid intima-media thickness relative to all other groups and more focal plaque when compared with white-collar workers. Risk factors and workplace characteristics did not account for the greater carotid atherosclerosis observed in clerical workers. Further research is needed to investigate why clerical work may increase cardiovascular risk.  相似文献

The current study compared cardiovascular risk profiles and trajectories (i.e., within-person changes) of women who were married or cohabitating and who had high relationship satisfaction with those of women with moderate or low satisfaction and with those of women who were single, divorced, and widowed. Participants were 493 women from the Healthy Women Study, a prospective investigation of health during and after the menopausal transition. Risk factors were measured across more than 5 occasions and 13 years, on average. Data were analyzed using a multilevel modeling technique. Overall, women in relationships with high satisfaction had lower levels of biological, lifestyle, and psychosocial risk factors when compared with the other groups. In some cases, women in satisfying marriages also showed a lower risk trajectory on risk factors relative to other women. Hence, marriage appears to confer health benefits for women, but only when marital satisfaction is high.  相似文献

Working memory span assesses the maximum number of items that can be remembered in the face of concurrent processing. Models of working memory differ on several dimensions, yet many rely exclusively on this span procedure for their evidence. Three experiments consider an alternative paradigm that attempts to capture the endurance limits for remembering a fixed number of items during concurrent processing. Eight-year-old children performed two versions of this working memory period measure--operation period and reading period. Period scores show healthy test-retest reliability and external validity for scholastic attainment, comparing well with span scores in these respects. In addition, period is highly correlated with span and shows similar effects of varying the order in which stimuli are presented. We conclude that the durability of representations is an important factor in both span and period.  相似文献

The nominal competitor effect suggests that, when a person has two names associated with them, recall of either name is more difficult than if they just had one name. Drawing on a connectionist framework, this effect could arise either if multiple names were represented as being connected to a single person identity node (PIN), or if multiple names were represented as being connected via one-to-one links to multiple PINs. Whilst the latter has intuitive appeal, results from two experiments support the former architecture. Having two names connected to a single PIN not only gives rise to a nominal competitor effect (Experiment 1), but also gives rise to a familiarity enhancement effect (Experiment 2). These empirical results are simulated using an extension of Brédart, Valentine, Calder, and Gassi's (1995) connectionist architecture, which reveals that both effects hold even when the association of both names to the PIN is unequal. These results are presented in terms of a more complete model for person recognition, and the representation of semantic information within such a model is examined.  相似文献

Gustavo Gutiérrez develops an account of human action or praxis that I—borrowing the language of Charles Taylor—label expressivist. Human action must be understood as expressing an underlying potential or impulse that only becomes real through expression in action. Gutiérrez's expressivism is fundamental to his view of the relationship between faith and love, his notion of three dimensions of liberation/salvation, and his understanding of the fundamental option as a yes or no in response to grace. Moreover, it supports a valuable approach to community as defined more by shared actions than a shared tradition or narrative. The final section briefly indicates two limitations to Gutiérrez's vision—especially with regard to the conception of community—and suggests the direction that a constructive appropriation of his thought might take.  相似文献

This essay seeks to develop and illustrate an approach to comparison based on ad hoc frames. A frame is defined by a question, to which different thinkers can be seen as offering complementary and/or competing responses. Pursuing a middle ground between universalist conceptions of comparison and particularist rejections of comparison, this approach brings various positions into dialogue in a manner that is not inherently totalizing. The article draws extensively on Hegel's philosophy of religion to articulate this approach to comparison and its presuppositions. The second section of the essay seeks to illustrate the value of this approach by using the question of how traditional practices are inherited to frame a comparison of Hegel on habit and the Confucian thinker Xunzi on ritual. This comparison functions principally to indicate the process of comparison and suggest the value of pursuing this comparison in greater depth.  相似文献
