This paper studies persuasion within teams and investigates why teams commonly take, by some measures, better decisions than individuals. The analysis is based on data from electronic communication within teams of two players. Thanks to the experimental design, changes of an individual’s decision can be attributed to the content of the team partner’s message. The results for knowledge-related and strategic problems show that individuals’ decisions change upon receiving more informative and sophisticated arguments and remain the same otherwise. This individual behavior is an essential part of the information aggregation in teams and can explain the advantage of teams in decision making and in games. 相似文献

High-tech research infrastructure is essential for state-of-the-art research, but requires many resources. Relatively weak actors, such as SMEs, cannot secure enough of those. Applying the concept of collaborative consumption via digital platforms, we examine the cooperative behavior of Korean SMEs that share research equipment to overcome their lack of resources. Also, we analyze configurations of a collaborative consumption network using the Exponential Random Graph Model. Network structural factor analysis shows sufficient effects of network positive feedback through cooperative consumption with a variety of popular providers and attributes analysis shows that SMEs frequently engage in collaborative consumption with their counterparts in the same region. This new cooperative model can achieve a virtuous cycle of policies, as it increases the efficiency of research infrastructure, preventing the unnecessary building of new research equipment and enabling relocation of underutilized infrastructure and online reservation of equipment. 相似文献

关于教派因素在叙利亚危机中作用的现有研究多持工具论观点,忽视了教派身份认同被精英工具化的必要条件以及教派动员的微观机制。本文认为,教派因素确非叙利亚危机爆发的根本原因,但阿萨德家族统治时期叙利亚社会长期积累的教派间利益分流、社会区隔和敌对情绪,一定程度上构成了危机教派化的前提条件和大众动员的最初框架。2011年叙利亚危机爆发伊始,民间自发的地方性教派动员和暴力已然出现。叙国内外精英通过不同政策迅速直接或间接介入民间自发性的教派动员,制造或强化了历史积累和新近出现的教派敌意、利益冲突、能力、机会等因素,触发并加剧了“安全困境/暴力螺旋”和“群体内—群体间交互作用”两大机制,最终导致了危机的教派化。 相似文献

Parents with substance use disorders (SUD) require treatment and support in order to provide children with appropriate care and protection. Using the 2012 National Child Abuse and Neglect Data System (NCANDS), this paper analysed 464 313 substantiated child maltreatment reports to determine (i) the proportion and characteristics of reports involving substance abuse; and (ii) the child and caregiver/perpetrator (C/P) characteristics that predicted referral to treatment as recorded in service plans. Findings indicate that 12% (N = 53 234) of maltreatment reports involved C/P SUD. Yet, of those reports, only (19%) (N = 10 088) were referred to substance abuse treatment as part of their service plan, indicating a large gap between those who need treatment and those who receive it. This finding is important given that parental SUD is consistently linked to poorer child outcomes. Amongst other variables, reports indicate that C/P with co‐occurring emotional disturbance were three times more likely to be referred to treatment for SUD as part of service plans. Additional research is needed regarding the characteristics that distinguish C/P who receive referrals for SUD treatment in substantiated cases of child maltreatment. 相似文献

We propose new dynamic measures of uncertainty based on the notion of generalized dynamic entropy introduced in Di Crescenzo and Longobardi (2006). These can uniquely determine distribution functions in continuous and discrete cases, and the characterizations of some well-known distributions are provided. We also define some orderings and aging notions based on the generalized dynamic measures, and prove some of their properties, obtaining as corollaries results that have recently appeared in the literature. 相似文献

In this article, we lament the effects of practice-distant research and associated policy initiatives on contemporary children's services in England. In the last decade, as a result of high profile inquiries into non-accidental child deaths, statutory children's social care services in the UK have been subject to a wide-reaching ‘modernization’ programme. We studied decision-making in the high blame environment of local authority children's services. Our research sought to examine the relationship between performance management and the impact of anticipated blame within the decision-making practices of those providing, supervising and managing these services. We show that systems and technologies can be developed which both assist the users in their daily work and achieve desired organizational goals, but without an ethnographically informed, practice-near approach, unsafe work regimes and practices can ensue. 相似文献

This article deals with the quantitative Fault Tree Analysis (FTA) and the estimation method of the top-event in case of dependent events. It aims at addressing two main issues: (1) the decomposition of variability for the top-event according to several error components linked to the estimation of the top-event and sources of internal and external variations for a complex system; and (2) the definition of a Performance Measure Independent of Adjustment in order to set the quality of the top-event as a complex measure of the system failure. A simulated study applied to the health system is also carried out. 相似文献
