Longitudinal Mediators of Relations Between Family Violence and Adolescent Dating Aggression Perpetration

Few longitudinal studies have examined the pathways through which family violence leads to dating aggression. In the current study the authors used 3 waves of data obtained from 8th‐ and 9th‐grade adolescents (N = 1,965) to examine the hypotheses that the prospective relationship between witnessing family violence and directly experiencing violence and physical dating aggression perpetration is mediated by 3 constructs: (a) normative beliefs about dating aggression (norms), (b) anger dysregulation, and (c) depression. Results from cross‐lagged regression models suggest that the relationship between having been hit by an adult and dating aggression is mediated by changes in norms and anger dysregulation, but not depression. No evidence of indirect effects from witnessing family violence to dating aggression was found through any of the proposed mediators. Taken together, the findings suggest that anger dysregulation and normative beliefs are potential targets for dating abuse prevention efforts aimed at youth who have directly experienced violence.     

传统音乐在学校的传承：国际议题和挑战

传统音乐是每个国家都具备的文化元素之一，透过学习和传承传统音乐，可以有效继承和发展自身的本土文化；然而传统音乐在学校课程中面对多方困难和挑战，亚洲各国多以西方音乐作为学校音乐课程的主导，传统音乐则被边缘化。本文先审视传统音乐在当代音乐环境中面临的困境，再介绍一个全面了解音乐传统的理论架构，从而了解不同的音乐传统的独特性和价值，提出音乐文化并无高低之分，并寄语有关当局重新审视本土传统音乐文化在学校教育中的价值和地位。     

少数民族神话传播内容的叙事传输研究——从藏族创世神话谈起

少数民族神话是民族文化的重要组成部分,对于少数民族神话的本体、类型、演变等相关研究已经举不胜举,但对于民族神话传播的研究一直以来相对薄弱。以藏族创世神话为例,基于对藏族创世神话内容的生态特征分析,从叙事传输视角审视藏族创世神话内容,剖析藏族创世神话叙事传输的影响因子和神话在传输过程中的损耗问题,试图对民族神话传播研究有所突破,并且从学科交叉与跨学科的研究中对学科体系完善进行探析。     

卖空压力对企业债券期限选择的影响——来自中国放松卖空管制准自然实验的证据

放松卖空管制后,投资者可通过挖掘公司“坏消息”在资本市场投资获利,在允许被卖空情境中,公司内部股东和管理层面临股价下行压力增大,会积极采取行动以规避被卖空的风险。借助中国证券市场2010年开始逐步放松卖空管制的准自然实验,以2007—2015年上市公司为样本,考察卖空压力对企业债券契约的影响。研究发现:放松卖空管制与企业债券期限显著负相关,特别是在大股东持股比例较高和管理层市场压力更大时。进一步分析发现,放松卖空管制与企业债务期限结构显著负相关,表明放松卖空管制会促使企业缩短发行债券的期限。研究结果显示,面对放松卖空管制引起的股价下行压力,公司大股东和管理层为了规避被卖空风险,会积极选择缩短发行债券期限以传递信号,证实了卖空机制对改善市场信息环境的积极作用。政府可以通过加强卖空机制制度建设和监管,推动企业调整行为决策,降低信息不对称。     

基于家庭策略的贫困代际传递治理

家庭是贫困治理的社会基础,有效阻断贫困的代际传递是贫困治理的重要方式。基于家庭策略的视野,通过对两个贫困家庭在减贫过程中不同减贫方式的分析与比较,探讨家庭策略如何被自主运用来解决贫困问题。研究发现,“反馈模式”的代际关系下,多子女所带来的路径可选择性与关系灵活性让家庭有更大空间采用有效的家庭策略,以“代内合力”和“代际合力”为一部分子女的成长和发展提供更充分的资源及“资源变现”的空间与条件,从而为实现“家庭减贫”创造机会。在巩固脱贫成果和实现乡村振兴进程中,家庭作用的有效发挥能充分激发家庭自我发展的内生动力,从而实现脱贫致富。     

Family Involvement and Holocaust Salience among Offspring and Grandchildren of Holocaust Survivors

The present research focuses on family involvement reported by offspring and grandchildren of Holocaust survivors (OHS and GHS, respectively). Study 1 included a convenience sample of 75 participants, divided into 2 groups (36 OHS and 39 comparisons). Study 2 included a convenience sample of 92 dyads of OHS and GHS. Both samples completed the Family Involvement Questionnaire and the Holocaust Salience Scale. In line with the hypotheses, Study 1 found that, relative to comparisons, OHS presented greater familial involvement. Only OHS with strong family involvement showed higher Holocaust salience than comparisons. Study 2 showed higher familial involvement among OHS as compared to GHS, and significant parent-child correlations. The results show that family involvement is related to intergenerational transmission of the trauma, especially among OHS. Yet, among OHS and GHS, parents’ and children’s family involvement were associated. The theoretical and practical implications of these findings are discussed.     

Optimization of Cascade‐Resilient Electrical Infrastructures and its Validation by Power Flow Modeling

Large‐scale outages on real‐world critical infrastructures, although infrequent, are increasingly disastrous to our society. In this article, we are primarily concerned with power transmission networks and we consider the problem of allocation of generation to distributors by rewiring links under the objectives of maximizing network resilience to cascading failure and minimizing investment costs. The combinatorial multiobjective optimization is carried out by a nondominated sorting binary differential evolution (NSBDE) algorithm. For each generators–distributors connection pattern considered in the NSBDE search, a computationally cheap, topological model of failure cascading in a complex network (named the Motter‐Lai [ML] model) is used to simulate and quantify network resilience to cascading failures initiated by targeted attacks. The results on the 400 kV French power transmission network case study show that the proposed method allows us to identify optimal patterns of generators–distributors connection that improve cascading resilience at an acceptable cost. To verify the realistic character of the results obtained by the NSBDE with the embedded ML topological model, a more realistic but also more computationally expensive model of cascading failures is adopted, based on optimal power flow (namely, the ORNL‐Pserc‐Alaska) model). The consistent results between the two models provide impetus for the use of topological, complex network theory models for analysis and optimization of large infrastructures against cascading failure with the advantages of simplicity, scalability, and low computational cost.     

格萨尔藏戏传承实践及文化表征

格萨尔藏戏将口头诗歌中的“歌”化为具体的表演行为动态实践，集声音、舞蹈、仪式和群体互动等多种形式于一体，是历史悠久、别具特色的藏戏剧种。格萨尔藏戏表演通过对古典时代民族民间文化的重构与想象，构成格萨尔史诗更丰富宽广的表达。作为文化象征的表述符号，格萨尔藏戏是口头传统研究中的表演民族志，其歌舞形态为本的言说系统，更贴近格萨尔史诗说唱本体，并重新廓清格萨尔史诗口传与书写之间复杂的关联，还口头说唱以本原。格萨尔史诗戏剧化表演实践与创新中的复合性、融合性、新生性特征和带有实验性的探索，使格萨尔藏戏经历新的蜕变。
