This paper reports the first cross-study competitive test of thecore solution in side-payment games where the core is nonempty and nonunique (i.e., larger than a single point). The core was tested against five alternative theories including the Shapley value, the disruption nucleolus, the nucleolus, the 2-center, and the equality solution. A generalized Euclidean distance metric which indexes the average distance between an observed payoff vector and the entire set of predicted payoff vectors (Bonacich, 1979) was used as the measure of goodness-of-fit. Analysis of data assembled from six previously reported studies (encompassing a total of 1,464 observations over 56 3-person and 4-person side-payment games) showed the core to predict less accurately than the Shapley value, disruption nucleolus, and nucleolus solutions (p < 0.01). These findings are consistent with previous empirical results that show the core to have a low level of predictive accuracy in side-payment games.This research was supported by grants SOC-7726932 and SES-8015528 from the National Science Foundation. Data analysis was performed at the Madison Academic Computing Center. 相似文献

Door supervision work is traditionally seen as a working‐class, male‐dominated trade. In addition, it is deemed to be one that is physically risky, where violence is seen as a ‘tool of the trade’ and where ‘bodily capital’ and ‘fighting ability’ are paramount to the competent performance of the job. This paper is a timely analysis on the manner in which the increasing numbers of women who work in door supervision negotiate their occupational identity and construct their work practices. The analysis focused on the way in which discursive constructions of both violence and workplace identities are variably taken up, reworked and resisted through the intersection of gender and class. This resulted in the identification of two main discourses; ‘playing the hero’ and the ‘hard matriarch’. These findings allow us to theorize that multiple, gendered and classed occupational identities exist beyond normative expectations and can be seen to be both emancipatory for working women, while simultaneously bolstering exploitation, workplace harassment and violent practices. 相似文献

Emotion‐focused therapy (EFT; Greenberg & Johnson, 1988 Emotionally focused therapy for couples. New York: Guilford Press) is anchored in attachment theory (Johnson, 2003 Attachment processes in couples and families. New York: Guilford) and considers change in attachment schemas essential in the process of improving satisfaction in relationships (Johnson, 1999, Research and couples therapy: Where do we go from here? American Family Therapy Academy Newsletter). However, there are little data on how measures of attachment change over the course of EFT or any other couple therapy. The current study examines whether increases in attachment security predict improvements in marital satisfaction during behavioral couple therapy, which would suggest that change in attachment style is a key process variable even for a non‐attachment‐focused treatment. Multilevel models of data from 134 couples participating in a randomized clinical trial of integrative behavioral couple therapy and traditional behavioral couple therapy (Christensen et al. Journal of Consulting and Clinical Psychology, 72, 2004, 176) indicate that although there is a trend for early change in attachment‐related anxiety and avoidance to predict later change in marital satisfaction, early change in marital satisfaction strongly predicts change in attachment‐related anxiety through the end of treatment and 2‐year follow‐up. These findings suggest that changes in satisfaction may lead to changes in attachment rather than the reverse and that change in attachment may not be the mechanism of change in all efficacious couple therapy. 相似文献

This study used a nationally representative sample of middle and high school students to examine the degree to which economic, neighborhood, school, and family factors contributed to three points on a proposed school outcome continuum: (1)avoidance of problem behavior, (2)sense of school coherence, and (3)grades. Multilevel models were employed to account for the clustering of students inside schools. Results suggested that though family and neighborhood social factors contribute to variance in school outcomes, family and neighborhood economic factors revealed the largest potential to explain and therefore present leverage points to reduce race and ethnicity achievement gaps. 相似文献

Brief therapy is widely perceived to be a very technique oriented and outcome focused endeavour, with limited interest in the fluidity of the relationship between the therapist and client. This perception exists despite the absolute priority brief therapy has always placed on building a cooperative relationship between therapist and client. Certainly, the brief therapy tradition has almost completely avoided talking about ‘empathy’ and the emotional realm, almost as if it is inappropriate for a brief therapist to discuss them. This paper suggests firstly that brief therapy is enhanced, rather than diminished, by engaging with both empathy and affect, and secondly, that the conception and practice of empathy can itself be enhanced by the rich tradition of skills and experience that brief therapy offers. Case material is used throughout this paper to illustrate the authors’ views. 相似文献
