We develop a theory of dishonesty based on neurophysiological evidence that supports the idea of a two-step process in the decision to cheat. Formally, decisions can be processed vía a costless “honest” channel that generates truthful behavior or vía a costly “dishonest” channel that requires attentional resources to trade-off costs and benefits of cheating. In the first step, a decision between these two channels is made based on ex-ante information regarding the expected benefits of cheating. In the second step, decisions are based on the channel that has been selected and, when applicable, the realized benefit of cheating. The model makes novel predictions relative to existing behavioral theories. First, adding external complexity to the decision-making problem (e.g., in the form of multi-tasking) deprives the individual from attentional resources and consequently decreases the propensity to engage in dishonest behavior. Second, higher expectations about the benefits of cheating results in a higher frequency of trial-by-trial cheating for any realized benefit level. Third, multiplicity of equilibria (characterized by different levels of cheating) emerges naturally in the context of illegal markets, in which expected benefits are endogenous.  相似文献

随着电子商务的蓬勃发展,“通知—删除”规则在有效制止电子商务专利侵权中具有重要作用。我国在21世纪初引进“通知—删除”规则,逐步构建了适用于电子商务领域专利侵权的“通知—删除”规则。《民法典》正式施行以来,“通知—删除”规则在适用于电子商务专利侵权中暴露出诸多问题:存在规则滥用隐患,权利人与商家利益失衡,通知与反通知的审核标准难以一致,因错误通知造成商家损失难以恢复,等等。解决好这些问题,需从专利侵权的特殊性出发,贴合《民法典》第1195条的规定,遵循“通知—删除”规则的立法目的进行解释适用;应重视和探索电子商务平台的自治能力,推动“通知—删除”规则在电子商务专利侵权中的解释适用。  相似文献

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.  相似文献

本研究以2008年和2009年在北京市、上海市和广东省进行的“中国家庭追踪调查”的数据为基础,运用多层线性模型和协方差模型探讨了社会网络对生活满意度的影响程度。研究表明,拜年网中朋友的比例、邻里互动频率和非正式社会参与都对生活满意度有积极影响,生活满意度与拜年网规模之间则呈现出“∩”型的相关关系。协方差分析结果表明,社会网络规模的扩大、朋友比例的上升和非正式社会参与频率的增加都有助于提高个人的生活满意度,但邻里互动频率的变化对个人生活满意度的提升作用还有待进一步的研究。  相似文献

Over the past 30 years a systemic approach has been applied to complex cases involving intellectual disability and behaviours of concern. This paper describes a model that draws on systemic family therapy and network therapy as well as the use of a reflective team. A single session intervention was provided for families of people with intellectual disability. A systemic consultation was used as a pre‐session meeting for professionals working with the family. The systemic consultation and single session therapy allowed the family and the professional network to gain insight. Involving the professionals in the therapy session also enhanced the alliance between professionals and family. This approach assists everyone involved in the case to find a way to progress.  相似文献

In this paper we propose a new method for studying local and global clustering in networks employing random walk pairs. The method is intuitive and directly generalizes standard local and global clustering coefficients to weighted networks and networks containing nodes of multiple types. In the case of two-mode networks the values obtained for commonly considered social networks are in sharp contrast to those obtained, for instance, by the method of Opsahl (2013), and provide a different viewpoint for clustering. The approach is also applicable in questions related to the general study of segregation and homophily. Applications to existent data sets are considered.  相似文献

Research on the role of social networks in human migration has mainly relied on single snapshots in time. This paper focuses on the changes in composition and usage of the transnational networks of migrants and why these changes occur. It is based on ethnography and network analysis with forty sub-Saharan African migrants in two transit contexts: Turkey and Greece, over a 17-month period. Findings show that relationship preferences, resources and communication infrastructures constitute an individual opportunity infrastructure affecting how critical events produce network changes. This process is ongoing through the continued experience of critical events, suggesting that the role of networks fluctuates over time.  相似文献
