The following reflections were originally an oral response to issues raised in Lee Yearley's presentation in May 2009 at Harvard Divinity School. As written here, they follow upon his oral and now written comments, highlighting key issues and points for development, drawing on this respondent's expertise in comparative and Hindu studies.  相似文献

This study uses data collected using a 360°-assessment instrument to investigate the structural equivalence of 360°-assessment ratings, according to rater type, controlling for organizational level. Data from 533 managers and their raters were employed in the study, which used multi-group structural equations modeling. Issues central to the implementation and use of 360°-assessment data are also considered within the context of current research and practice.  相似文献

Adult-child interactions during stressful medical procedures were investigated in 43 pediatric patients videotaped during a venipuncture procedure in the course of cancer treatment. Relations among six adult behavior categories (explain, distract, command to engage in coping behavior, give control to the child, praise, and criticize/threat/bargain) and three child behavior categories (momentary distress, cry/scream, and cope) were examined using correlational and sequential analysis. Results indicated that adult distraction resulted in increased child coping and reduced momentary distress and crying. Adult explanations, although a likely response to child distress and crying, did not result in a reduction of these behaviors. Attempts to give the child control reduced child crying. Implications for clinical interventions during painful medical procedures are discussed.  相似文献

Previous studies showed that random error can explain overconfidence effects typically observed in the literature. One of these studies concluded that, after accounting for random error effects in the data, there is little support for cognitive‐processing biases in confidence elicitation. In this paper, we investigate more closely the random error explanation for overconfidence. We generated data from four models of confidence and then estimated the magnitude of random error in the data. Our results show that, in addition to the true magnitude of random error specified in the simulations, the error estimates are influenced by important cognitive‐processing biases in the confidence elicitation process. We found that random error in the response process can account for the degree of overconfidence found in calibration studies, even when that overconfidence is actually caused by other factors. Thus, the error models say little about whether cognitive biases are present in the confidence elicitation process. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

The present study explored the availability of flexible work arrangements (FWA) and their relationship with manager outcomes of job satisfaction, turnover intentions, and work‐to‐family conflict (WFC) across country clusters. We used individualism and collectivism to explain differences in FWA availability across Latin American, Anglo, and Asian clusters. Managers from the Anglo cluster were more likely to report working in organisations that offer FWA compared to managers from other clusters. For Anglo managers, flextime was the only FWA that had significant favorable relationships with the outcome variables. For Latin Americans, part‐time work negatively related with turnover intentions and strain‐based WFC. For Asians, flextime was unrelated to time‐based WFC, and telecommuting was positively associated with strain‐based WFC. The clusters did not moderate the compressed work week and outcome relationships. Implications for practitioners adopting FWA practices across cultures are discussed.  相似文献

Human and experimental animal research suggests that social stress in general--and chronic, effortful attempts to exert social control in particular--may contribute to cardiovascular disease. We examined the effects of exerting social influence or control on cardiovascular responses in married couples. Compared to husbands discussing a problem with their wives, husbands attempting to influence or persuade their wives displayed larger increases in systolic blood pressure (SBP) before and during the discussion. Furthermore, these physiological effects were accompanied by increases in anger and a more hostile and coldly assertive interpersonal style. Although wives who engaged in social influence attempts displayed generally similar behavior, they did not show the elevated SBP response or anger. We discuss the results in terms of the social context of cardiovascular reactivity and potential marital factors in cardiovascular health.  相似文献
