Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors. 相似文献

The value of higher education is often implicit or assumed in educational research. The underlying and antecedent premises that shape and influence debates about value remain unchallenged, which perpetuates the dominant, but limiting, terms of the debate and fosters reductionism. The article proceeds on the premise that analyses of value are not self-supporting or self-referential but are embedded within prevailing cultures of valuation. It contends that challenging, and providing alternatives to, dominant narratives of higher education requires an appreciation of those cultures. It therefore highlights some of the existing cultures of valuation and their influence. It then proposes Sayer’s concept of lay normativity as a culture of valuation and discusses how it translates into the practices of research into higher education, specifically the practice of analysis. The discussion is animated by detecting the presence of lay normativity in the evaluative space of the capability approach. 相似文献

There is a lack of research that has examined public opinion on the importance of biosocial influences for understanding the potential causes of criminal and delinquent involvement. We address this gap in the current study by surveying a nationally representative sample of adults about the importance of biosocial factors for influencing criminal behavior. Results indicate that the public believes the environment matters more than genetic factors for determining whether someone becomes a criminal. However, the data also reveal an overall acceptance of the importance of neuropsychological factors for influencing criminal behavior. An ordered logistic regression analysis was also estimated to examine potential differences in opinion across demographic categories. The results revealed that income, gender, marital status, and employment status are significantly associated with whether a respondent supports the role of biosocial factors in crime causation. Implications of the findings are discussed. 相似文献

ABSTRACT Distal-to-proximal redistribution of joint work occurs following exhaustive running in recreational but not competitive runners but the influence of a submaximal run on joint work is unknown. The purpose of this study was to assess if a long submaximal run produces a distal-to-proximal redistribution of positive joint work in well-trained runners. Thirteen rearfoot striking male runners (weekly distance: 72.6 ± 21.2 km) completed five running trials while three-dimensional kinematic and ground reaction force data were collected before and after a long submaximal treadmill run (19 ± 6 km). Joint kinetics were calculated from these data and percent contributions of joint work relative to total lower limb joint work were computed. Moderate reductions in absolute negative ankle work (p = 0.045, Cohen’s d = 0.31), peak plantarflexor torque (p = 0.004, d = 0.34) and, peak negative ankle power (p = 0.005, d = 0.32) were observed following the long run. Positive ankle, knee and hip joint work were unchanged (p < 0.05) following the long run. These findings suggest no proximal shift in positive joint work in well-trained runners after a prolonged run. Runner population, running pace, distance, and relative intensity should be considered when examining changes in joint work following prolonged running. 相似文献

Stereotype reduction through humor and accommodation during imagined communication with older adults
Ageism can generate conflict and harm well-being. Our paper integrates the Aging Stereotypes in Interaction model with intergroup contact theory to predict how communicative elements mediate the effect of intergenerational contact on warmth and competence stereotypes of older adults as a group. Students (N?=?288) were randomly assigned to imagine having a conversation with an older adult in one of six experimentally manipulated contact conditions: a competent/incompetent older woman, a sociable/unsociable older woman, or a moral/immoral older woman. Participants’ stereotypes of older adults were affected by the characteristics of their communication partner, and this effect was mediated by specific communication behaviors imagined by the participant for two of the three trait dimensions. For perceptions of competence, overaccommodation was the key mediator. For perceptions of sociability, the key mediator was humorous communication. These mediators represent an expansion in how we understand not just the outcomes of intergroup contact, but also the communicative mechanisms through which it occurs. 相似文献
