This study examined the relationship between group conflict management styles and effectiveness of group decision making in 11 ongoing, naturally occurring workgroups from 2 large U.S. organizations. The major postulate of the study was that groups develop norms regarding how they will manage conflicts that carry over to affect other activities, such as decision making, even when these activities do not involve open conflict. To determine the impact of conflict management style on decision effectiveness, a longitudinal design was used that identified conflict management styles in the initial portion of each team's series of meetings and then analyzed a group decision taken in a meeting near the end of that series. Group conflict management styles were determined using observational methods, and decision effectiveness was measured using multiple indices that tapped member, facilitator, and external observer viewpoints. Task complexity also was considered as a possible moderating variable. The findings suggest that groups that developed integrative conflict management styles made more effective decisions than groups that utilized confrontation and avoidance styles. Groups that never developed a stable style were also less effective than groups with integrative styles.  相似文献

Two studies tested the hypotheses (1) that focusing on the process of goal pursuit is associated with lower levels of procrastination and (2) that this relationship is moderated by fear of failure and task aversiveness. Study 1 used a between-subjects design with hypothetical scenarios (N = 92). Study 2 used a 5-week longitudinal within-subject design in a real-life context (N = 50). Both studies found converging evidence for the main-effect hypothesis, that is, process focus is negatively associated with procrastination in the academic context (e.g., studying for an exam). Process focus was also negatively related to task aversiveness and fear of failure. However, findings regarding moderation effects of fear of failure and task aversiveness were mixed. Taken together, findings support the hypothesis that the cognitive representation of a goal primarily in terms of its means (i.e., process focus) versus its outcome is related to less procrastination: Focusing on the process of a task can help to reduce procrastination.  相似文献

Remarks On Quantum Ontology   总被引:2,自引:0,他引:2  
Krause  Décio 《Synthese》2000,125(1-2):155-167
Despite the discrepancies between quantum objects and `classical' ones, mainly with regard to the fact that the latter may be thought of as `individuals', contrary to the former, we still regard the quanta as `things' in our ordinary discourse as well as in the logico-mathematical basis of quantum theories. This paper considers some possibilities for accomodating the logico-mathematical framework of the theories which deal with such a strange ontology where the inhabitants are things devoid of identity and both having and not having certain properties.``All right', said the Cat; and this time it vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone.``Well! I've often seen a cat without a grin', thought Alice, ``but a grin without a cat! It's the most curious thing I ever saw in all my life!'Lewis Carroll  相似文献

The purpose of this study is to see how feelings of anticipated support arise in church. Anticipated support refers to the belief that coreligionists will provide assistance in the future if the need arises. This model contains the following hypothesis: (1) people who affiliate with conservative Protestant congregations will be more deeply committed to their faith, (2) individuals who are more committed to their faith will attend church more frequently, (3) people who go to church more often will be more likely to occupy church service roles, (4) those who occupy church service roles will feel more highly valued by their coreligionists, (5) individuals who feel they are valued highly by fellow church members will receive more emotional support from them, and (6) people who receive more emotional support at church will have stronger anticipated support beliefs. Data from a nationwide survey of older Mexican Americans support these hypotheses.  相似文献

Acute stress stimulates the expression and release of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) from the hypothalamus, and the pro-opiomelanocortin products beta-endorphin and ACTH from the anterior pituitary. These neuropeptides are also expressed in immune tissues, and it has been proposed that they may modulate immune responses to stress through paracrine mechanisms. We subjected rats to restraint stress or central injection of interleukin (IL)-1beta to determine whether these acute stimuli can alter the expression of neuropeptides in the spleen and thymus. Restraint stress significantly increased the contents of all these neuropeptides in thymic, but not splenic, extracts. A single icv injection of IL-1beta increased contents of CRH, AVP, ACTH and beta-endorphin in the spleens of both sham-operated and adrenalectomised (ADX) rats. IL-1beta increased thymic contents of CRH and ACTH in sham-operated rats but these increases were not observed in ADX rats. These results suggest that the effects of IL-1beta on neuropeptide expression in the spleen are independent of glucocorticoids, whereas IL-1beta stimulation of neuropeptide expression in the thymus is dependent on circulating glucocorticoids. There were significant correlations between increases in CRH, ACTH and beta-endorphin in the spleen, and between CRH and ACTH in the thymus, consistent with the suggestion that IL-1beta-induced increases in ACTH and beta-endorphin may be mediated through CRH. These results provide evidence that stressors can directly influence neuropeptide expression in immune tissues. Thus stress may influence immune functions through paracrine mechanisms involving locally synthesised neuropeptides as well as through activation of the hypothalamo-pituitary-adrenal axis.  相似文献

With approximately one out of six married couples experiencing infertility, having a basic knowledge of infertility is important to marriage and family therapists. This paper presents important themes that infertile couples often struggle with and stresses the importance of having a biological, psychological, and social understanding of infertility. In addition, the paper suggests possible interventions that family therapists can use in helping infertile couples.  相似文献
