A review is presented of empirical research on the effects of gender and power on the use of influence strategies in interpersonal relationships. Several variables are considered, including gender, power, status, relationship of agent to target, and the goal of the influence attempt. Although gender appears to account for some of the findings, power and status are more critical variables in choice of power strategies. Because gender is inextricably linked to power and status, the relationship of gender to influence strategy usage can only be understood in terms of its relationship to power and status.  相似文献

The current study hypothesized that (1) hope would negatively predict burdensomeness, thwarted belongingness, and acquired capability to enact lethal injury; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results indicated that hope negatively predicted burdensomeness and thwarted belongingness, but positively predicted acquired capability to enact suicide. Contrary to our second hypothesis, hope did not predict suicidal ideation, but interpersonal risk factors for suicide predicted suicidal ideation. Results are discussed in terms of implications for hope theory and Joiner's (2005) interpersonal risk factors for suicide, and for clinical practice.  相似文献

Self‐abandonment and self‐denial are, respectively, Catholic and hyper‐Calvinist analogues of each other. Roughly, each requires the surrendering of a person to God's will and providence through faith, hope, and love. Should the self‐abandoning/self‐denying individual accept his or her own damnation if that be God's will? This article, which is virtually alone in discussing the Catholic and Reformed Protestant traditions together, answers “No.” The unqualified self‐abandonment present in quietism and the radical self‐denial of Samuel Hopkins are perverse and irrational responses to the prospect of hell because they run counter to the Christian's deepest need to spend eternity with God. However, a qualified self‐abandonment is intellectually defensible and offers a viable Christian piety.  相似文献

abstract In Political Liberalism and later work John Rawls has recast his theory of justice as fairness in political terms. In order to illustrate the advantages of a liberal political approach to justice over liberal non‐political ones, Rawls discusses what kind of education might be required for future citizens of pluralistic and democratic societies. He advocates a rather minimal conception of civic education that he claims to derive from political liberalism. One group of authors has sided with Rawls’ political perspective and educational proposal, holding that a political approach and educational requirements that are not too demanding would have the advantage of being acceptable to a wide range of citizens with different religious, moral and philosophical perspectives. A second group of authors have criticized Rawls’ educational recommendations, holding that the production of a just society composed of reasonable citizens requires a more demanding civic education and, hence, that the political approach is not viable. The present paper argues that both groups are only partially right, and that there is a third way to understand civic education in Rawlsian terms, a way that is political but not minimal.  相似文献

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure.  相似文献

A meta-analysis of published studies with adult human participants was conducted to evaluate whether physical fitness attenuates cardiovascular reactivity and improves recovery from acute psychological stressors. Thirty-three studies met selection criteria; 18 were included in recovery analyses. Effect sizes and moderator influences were calculated by using meta-analysis software. A fixed effects model was fit initially; however, between-studies heterogeneity could not be explained even after inclusion of moderators. Therefore, to account for residual heterogeneity, a random effects model was estimated. Under this model, fit individuals showed significantly attenuated heart rate and systolic blood pressure reactivity and a trend toward attenuated diastolic blood pressure reactivity. Fit individuals also showed faster heart rate recovery, but there were no significant differences in systolic blood pressure or diastolic blood pressure recovery. No significant moderators emerged. Results have important implications for elucidating mechanisms underlying effects of fitness on cardiovascular disease and suggest that fitness may be an important confound in studies of stress reactivity.  相似文献

A national survey was conducted to compare the background and career characteristics of men and women engineers differing in the number of years since they completed their BS degrees (0–5, 6–10, 11–15, and 16–20 years). The parents of women engineers were more likely to have college degrees and to be employed in professional positions than were the parents of men engineers. Women engineers were less likely to be married and were more likely to be childless than were the men. Both men and women were influenced by courses and work–related factors in their decisions to pursue engineering, but men made their career decisions sooner than women. Although men and women reported comparable levels of technical responsibility in their present jobs, gender differences favoring men were found for supervisory responsibility and salary among those with more than five years of experience, with the gap between men and women increasing with experience. Men with 16–20 years of experience and all four degree cohorts of women endorsed the opinion that there are better opportunities for men than women in engineering.  相似文献
