Children in the United States are exposed to considerable community violence that has been linked to child functioning. However, not all those exposed, experience negative outcomes. Recent research has focused on factors that “buffer” or protect children from negative consequences of violence exposure. The purpose of this investigation was to examine the potential buffering or moderating role of maternal acceptance in the relationship between community violence exposure and internalizing and externalizing problems. Subjects were 268 urban African American first graders. Community violence exposure was significantly related to symptoms of post-traumatic stress, but did not correlate with either internalizing or externalizing problems for all children, after control for demographics, maternal mental health, and general life stress. However, children's perceptions of maternal acceptance moderated the relationship between violence exposure and internalizing and externalizing problems which included being withdrawn, anxious-depressed, and demonstrating delinquent behavior. Children with the lowest levels of self-reported maternal acceptance were most impacted by community violence. In this sample of urban first graders, low levels of maternal acceptance placed children at greater risk for adverse outcomes associated with community violence exposure compared to moderate and high levels of maternal acceptance.  相似文献

In a sample of 299 children (grades 2, 4, and 6), we examined parenting and negative life events as predictors of depressive cognitions, specifically low self-perceived competence, depressive cognitive schemas, and depressogenic attributional style. We also examined developmental trends in these relations. Children completed measures of parenting, negative life events, and depressive cognitions. Parents also completed measures of parenting and negative life events. Consistent with our hypotheses, negative parenting and negative life events corresponded with higher levels of depressive cognitions, whereas positive parenting corresponded with lower levels of depressive cognitions. The relations between negative parenting and negative automatic thoughts were stronger for older children. Theoretical and practical implications are discussed.  相似文献

Mentoring is prototypically intended to advance the personal and professional growth of new employees at work. Although meta‐analyses have found that receiving mentoring can result in beneficial outcomes for employees' career success, employees may perceive barriers to obtaining a mentor. The present research examined antecedents and consequences to perceived barriers to mentoring in business and administrative jobs in a field study over 2 years. Socioeconomic origin, positive affectivity, organizational development culture, and previous mentoring experience predicted perceived barriers to mentoring after 2 years. New employees' perceived barriers to mentoring at Time 1 predicted changes in mentoring received and income after 2 years. Implications of this study, including a proposed mentoring training program, and directions for future research are discussed.  相似文献

This paper examines Spinoza's remarks on women in the Political Treatise in the context of his views in the Ethics about human community and similitude. Although these remarks appear to exclude women from democratic participation on the basis of essential incapacities, I aim to show that Spinoza intended these remarks not as true statements, but as prompts for critical consideration of the place of women in the progressive democratic polity. In common with other scholars, I argue that women, in Spinoza's system, are deprived of freedom and political participation not by their essential natures, but by their social and historical circumstances. I differ from other scholars, however, in basing this conclusion on the different critical functions of the Political Treatise and the Ethics. Following that critical comparison, I consider Spinoza's views on the `natural right' of women and their equal capacity for political participation in terms of his arguments for the compositional similarity of men and women. Finally, I argue that Spinoza offers an explanation for women's actual disempowerment through his account of economic dependence within marriage.  相似文献

This paper explores the relation of order and welfare for Han Fei's philosophy. It will be claimed that the Legalist did indeed show concern for the overall quality of life of society, claiming that his model state would lead to a substantial increase for the individual's welfare. On the other hand, although he acknowledges (and cares) for these positive consequences, Han Fei does not attach any value for legitimizing the system he proposes to them. Even if there were any value attached to benefitting the people, it would be indirect. For Han Fei, a welfare does not legitimize the system but is a consequence of the ‘right system’. He is not concerned with letting the people live better for the sake of the people, but rather with having healthy and motivated subjects, as these are at the same time consequences of, and requirements for, a strong and stable state. The novelty of this paper is to interpret Han Fei's philosophy as welfare-maximization through a specific understanding of the role of virtue.  相似文献

Subjects made a speeded stylus movement along a track to a stop and simultaneously performed a simple reaction-time task designed to assess the processing demands of the movement task. Movement task variables were: (a) number of alternative ending positions — either one or two — with the choice executed during movement, and (b) presentation time for the endpoint signals in the two-choice conditions, either prior to movement initiation (immediate) or during movement execution (delay). Processing demands were higher during all movement conditions than in a control condition that did not require movement. Processing demands during execution of the one-and two-choice movement with immediate signals did not differ. However, processing demands during the two-choice movements with delayed signals were higher than demands during the two-choice movement with immediate signals.  相似文献

The authors investigated how brain activity during motor-memory consolidation contributes to transfer of learning to novel versions of a motor skill following distinct practice structures. They used 1 Hz repetitive Transcranial Magnetic Stimulation (rTMS) immediately after constant or variable practice of an arm movement skill to interfere with primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC). The effect of interference was assessed through skill performance on two transfer targets: one within and one outside the range of practiced movement parameters for the variable practice group. For the control (no rTMS) group, variable practice benefited delayed transfer performance more than constant practice. The rTMS effect on delayed transfer performance differed for the two transfer targets. For the within-range target, rTMS interference had no significant affect on the delayed transfer after either practice structure. However, for the outside-range target, rTMS interference to DLPFC but not M1 attenuated delayed transfer benefit following variable practice. Additionally, for the outside-range target, rTMS interference to M1 but not DLPFC attenuated delayed transfer following constant practice. This suggests that variable practice may promote reliance on DLPFC for memory consolidation associated with outside-range transfer of learning, whereas constant practice may promote reliance on M1 for consolidation and long-term transfer.  相似文献

Two experiments examined the interaction of vision and articular proprioception in simple one-hand catching. In Experiment 1 (N = 18) skilled baseball and Softball players used the left and right hands to catch slowly moving tennis balls, while Experiment 2(N = 16) used novice catchers as subjects. In half the trials, sight of the catching hand was prevented by placing a screen alongside the subjects’ face. Results of Experiment 1 revealed that the screen caused minimal disruption of the positioning phase of the catch, with moderate disruption of the grasping phase. However, for the unskilled subjects of Experiment 2, the screen caused considerable disruption of positioning. The data provide only minimal support for Smyth and Marriott’s (1982) contention that limb position is inadequately specified by articular proprioception. It is argued that skill level serves as a mediator in the ability to use proprioception for limb positioning, but vision appears necessary to control the precise temporal organization of the grasp phase of one-hand catching.  相似文献
