The competitive bargaining set for cooperative n-person games

The continuum of solutions constituting the bargaining set for n-person games in characteristic function form (n ≥ 4) reflects various degrees of determinateness to form a coalition, different requirements of stability, or different levels of competition among the players. At one end of this continuum is the kernel solution. A new solution, called the competitive bargaining set, constitutes the other extreme. It incorporates the concept of a multiobjection, which is based on the idea that threats may be perceived and considered simultaneously even though their simultaneous implementation is impossible.For the simple homogeneous majority games [n ? 2, 1, 1, …, 1] the competitive bargaining set (1) yields unique outcomes for each coalition structure, (2) coincides with von Neumann and Morgenstern's main simple solution for certain coalition structures, and (3) converges to Shapley value as n → ∞ when the grand coalition forms.Mathematical and experimental implications of the new solution are discussed briefly.     

Perceived characteristics of “competent” people

The purpose of this research was to determine the specific behaviors and cues which 104 assessors perceived as indicating the presence of psychological variables shown to be related to competent job behavior. The cue systems utilized were found to be reminiscent of theory Y conceptions of effective job behavior. Implications of the lack of correlation of cue utilization with assessor characteristics are discussed.     

Workplace and family support and work–life balance: Implications for individual psychological availability and energy at work

This study presents three studies that explore the ways in which multiple support sources (workplace and family social support) help individuals to experience work–life balance (WLB) and thereby develop a sense psychological availability and positive energy at work. We examine this serial mediation model across three population groups in Israel using time-lagged data from part-time students (sample 1), as well cross-sectional data from workers in the industrial sector (sample 2) and physicians in public hospitals (sample 3). The results indicate a complex process in which workplace and family support augment employee positive energy through WLB and psychological availability. The findings shed light on the importance of support from work and nonwork sources for the pursuit of employees to achieve balance in the spheres of work and life and suggest that the WLB helps in the development of psychological availability and augmenting employee positive energy.     

Coping with war captivity: the role of attachment style

The current study examines the implication of attachment style in both immediate coping and long-term adjustment of prisoners of war (POWs). 164-ex-POWs and 184 matched controls filled out a battery of questionnaires, 18 years after the war. They were questioned about their subjective experience of captivity, current mental health status, and characteristic attachment style. Secure individuals, who reported lower levels of suffering, less helplessness and more active coping during captivity, exhibited better long-term adjustment. Avoidant ex-POWs, who reported helplessness and hostility, and ambivalent individuals, who felt abandoned and vulnerable, reported long-term maladjustment. The role of attachment style as a stress-moderating resource is discussed. © 1998 John Wiley & Sons, Ltd.     

Bridging Science and Practice in Violence Prevention: Addressing Ten Key Challenges

This article illustrates ideas for bridging science and practice generated during the Division of Violence Prevention's (DVP) dissemination/implementation planning process. The difficulty of moving what is known about what works into broader use is near universal, and this planning process pushed us to look beyond the common explanations (e.g., providers were resistant/unwilling to change practice) and think about the multiple layers and systems involved. As part of this planning process, the Interactive Systems Framework for Dissemination and Implementation (ISF) was developed and then applied to the fields of child maltreatment and youth violence prevention. Challenges for each of the three systems in the ISF are discussed as well as and action and research ideas to address the challenges. Also described are actions taken by DVP in response to the planning process to illustrate how a funder can use the ISF to bridge science and practice.
