Three striking features about both interstate and civil war are (1) there are often periods of persistent fighting, (2) fighting commonly ends in negotiated settlements as well as in militarily decisive outcomes, and (3) fighting sometimes recurs. This article links these features to shifts in the distribution of power and to the fact that one of the functions of fighting is to forestall adverse shifts. The analysis centers on a simple model of state consolidation. The equilibrium displays these features: Fighting occurs when the distribution of power is shifting rapidly. The factions avoid fighting and cut deals when the distribution of power shifts slowly or is stable. Fighting resumes if the distribution of power again begins to shift rapidly. The analysis also shows that state consolidation can occur without fighting if the process is sufficiently slow. Fighting now rather than later can also reduce the total cost of fighting. 相似文献

We present three studies examining the role of prior job experience in interviewing and interviewers' ability to learn open-ended questions during a training program. We predicted a negative relationship such that more experienced interviewers would perform worse after training than less experienced interviewers, and that (irrespective of baseline performance) the more experienced interviewers would improve the least during training. These predictions were made for two reasons. First, specific questions are commonly used in the workplace (i.e. open-ended questioning constitutes new learning). Second, experience in the use of specific questions potentially interferes with newly learned open-ended questions. Overall, our predictions were supported across different participant samples (including police officers specialized in child abuse investigation and social workers from the child protection area), time delays, and modes of training. The results highlight the need for investment in ongoing investigative interviewing training commencing early during professionals' careers, prior to the establishment of long-term habits in the use of specific questions. 相似文献

Parents with disabilities contend with bias within the family law system, often threatening their custody and visitation rights. The overarching goal of this article is to explore the experiences of parents with disabilities involved in custody and visitation disputes and the application of the Americans with Disabilities Act (ADA) in these cases. This article begins with an overview of parents with disabilities and their interactions with the family law system. Next, the article examines the ADA and its applicability to custody and visitation disputes. Finally, the article offers thoughts about strategies that can be utilized by attorneys to ensure that the rights of parents with disabilities are protected. 相似文献

AbstractMothers in prison separated from their young children are an overlooked group. Attachment theory could provide a useful model to underpin interventions and better support women affected by separation from their infants. Current policy draws on a limited body of evidence and research has developed considerably since its first design. This review systematically searched all relevant UK prison policy and government documents with regards to mother and child separation in prison and analysed the extent to which these documents draw on attachment theory. Following initial searches, 58 documents were thematically analysed. Attachment was implicitly referred to in most documents but only explicitly mentioned in four. Global themes identified included ‘separation as trauma’. However, document groups varied in focusing either on the mother or the child and there were no joint perspectives. Developing and researching specific attachment-informed interventions might be one way forward as would further attachment-based research in this area. 相似文献

Paul Warwick ( 2016 ) argues that much of the research on ideological congruence leaves the erroneous impression that a close match of median left‐right voter opinions and government ideological positions usually emerges from elections. I propose further clarifications. I offer a “natural metric” based on the average distances from the median voter of the most distant and the closest parties competing in all these countries’ elections. I suggest that by these standards average ideological congruence in the Western liberal democracies in the last 20 years has been fairly successful, but not as successful as it could be. 相似文献

Although supervising persons with mental illness can pose special challenges for community parole/probation officers (PPOs), few studies have investigated whether the number of supervisees on an officer’s caseload increases risk for poor mental health for PPOs and whether this link is due to emotional exhaustion. Using statewide survey data from 798 PPOs, we examine whether the number of supervisees on an officer’s caseload with mental health problems is associated with depressive symptoms reported the PPOs and whether this relationship is mediated by emotional exhaustion. In addition, we evaluate the potential mitigating role of both mental health services received by supervisees and officer training in mental health in the relationship between the number of supervisees on an officer’s caseload with mental health problems and emotional exhaustion experienced by PPOs. Findings reveal that PPOs with more supervisees on their caseload report significantly higher levels of depressive symptoms and that this relationship is completely explained away by emotional exhaustion. Neither mental health services received by supervisees nor officer training in mental health mitigated the link between the number of supervisees on an officer’s caseload with mental health problems and officer emotional exhaustion. This study underscores the importance of the psychological well-being of those on parole/probation for the emotional and mental health of the officers who supervise them. 相似文献
