Tempered Mittag-Leffler Lévy processes

In this article, we introduce tempered Mittag-Leffler Lévy processes (TMLLP). TMLLP is represented as tempered stable subordinator delayed by a gamma process. Its probability density function and Lévy density are obtained in terms of infinite series and Mittag-Leffler function, respectively. Asymptotic forms of the tails and moments are given. A step-by-step procedure of the parameters estimation and simulation of sample paths is given. We also provide main results available for Mittag-Leffler Lévy processes (MLLP) and some extensions which are not available in a collective way in a single article. Our results generalize and complement the results available on Mittag-Leffler distribution and MLLP in several directions. Further, the asymptotic forms of the moments of the first-exit times of the TMLLP are also discussed.     

High value manufacturing (HVM) in the UK: case studies and focus group insights

This paper studies the internal mechanisms that allow organisations to become high value manufacturing (HVM). Using a qualitative methodology, three UK manufacturing companies formed in-depth case studies with semi-structured interviews, observations and historical data. The HVM value matrix of Martinez and co-workers is used to categorise each organisation’s value proposition. Wider benchmarking of the three organisations was carried out against a focus group with an additional seven manufacturing organisations. Thus, data from 10 manufacturing organisations are included in this research. The cases follow the ‘customer intimacy’ HVM discipline. The business processes supporting these value propositions were identified. Interestingly, each organisation’s desired value proposition differs from their current one. ‘Technological integrators’ predominantly rely on new product development (NPD) and Strategy processes, whereas ‘Socialisors’ rely predominantly on Strategy and Customer Relationship processes. Companies can use the findings to better understand their current HVM value proposition and, where necessary, plan their transition to a future desired HVM value proposition.     

中国社会养老的文化分析

本文关注福利文化对社会养老制度和实践的影响,从文化视角审视中国现代社会养老项目的发展,揭示了老年社会福利模式与特定社会政策制定者对社会福利概念的理解和传统福利文化之间的关系。限定主义的价值观和公民权利意识的缺失阻碍着中国老年社会福利模式从剩余性到制度性的转变,抑制了社会福利在缩小老年群体内阶层差异方面的作用,促使了福利资源分配的不公。尽管人口老龄化和福利国家的文化扩散正在促使中国老年社会福利呈多元化发展趋势,多元福利体系的最终建立还有赖于社会公众和政策制定者对个人和国家关系的重新解读。     

剩余权最优配置探寻与国有企业改革

由于不确定性的存在,企业合约不可能是完全的,因此,将无法完全的部分称之为剩余,而与剩余有关的一些权力,称之为剩余权。假定剩余权分为剩余索取权与剩余控制权,剩余索取权是针对不确定性产生的利润而言的,而剩余控制权是企业的一些生死攸关的决策,并将这两种权力统称为剩余权。既然剩余权力面临着配置问题,那么在理论上可能存在最优。我们通过对一元产权企业、二元产权结构企业与多元产权结构企业的分析得出企业剩余权的配置可能存在最优解,即当所有要素对应的剩余权力变化至要素的剩余权边际贡献相等时,企业的剩余权配置达到最优,而要素剩余权力边际贡献的改变则要依赖于要素的相对重要性,从而形成了由要素相对重要性为起点的均衡剩余权配置的关系,而由此得出的结论对国有企业改革可能会具有一定的启发性意义。     

剩余索取权与会计信息质量相关程度实证分析

当企业的利益相关者发生利益冲突时,会计信息蕴涵的各项权利才凸现出来。本文主要研究剩余索取权分享下的会计信息披露,通过国内上市公司样本统计数据,得出企业所有权的集中程度、管理层分享剩余索取权的程度与会计信息质量的高低有显著的相关性,提出相关建议,即剩余索取权的分享程度要适应我国资本市场的股权集中度,赋予管理层人员股票期权,更符合股权分置改革后我国上市公司的实际。     

二元股份结构上市公司的分配问题研究

我国股市结构是典型的二元股份结构,按照传统的平均分配理论,会出现大股东需要参与公司管理与监督而小股东只需搭便车就可以和大股东一样享受剩余分配的不公平现象。该文通过建立的二元所有权结构分配模型,很好地解决了这个问题,为合理分配公司剩余索取权、优化公司治理结构提供了公平有效的思路。     

Parenting in the Context of Deportation Risk

Nearly 5.1 million children younger than age 18 live with at least one undocumented parent, about 7% of the U.S. child population. Between 2010 and 2013, an estimated 300,000 parents of U.S. citizen children were deported. Raising children in the context of deportation risk increases overall parenting stress for undocumented Latino parents. To investigate this and understand the experience of undocumented parenting, the authors interviewed 70 undocumented parents in two Southwest cities from 2012 to 2013. The authors frame their analysis using the lens of the problem of “illegality.” There are three domains of stressors associated with parenting in the context of deportation risk: trapped parenting, threat of family separation, and altered family processes. The authors discuss these findings in the context of the literature on undocumented families and parenting stress and connect these findings to the current sociopolitical context experienced by Latino families in the United States .     

Model selection for Lévy measures in diffusion processes with jumps from discrete observations

We deal with parametric inference and selection problems for jump components in discretely observed diffusion processes with jumps. We prepare several competing parametric models for the Lévy measure that might be misspecified, and select the best model from the aspect of information criteria. We construct quasi-information criteria (QIC), which are approximations of the information criteria based on continuous observations.     

Communicative Correlates of Satisfaction,Family Identity,and Group Salience in Multiracial/Ethnic Families

Guided by the Common Ingroup Identity Model ( S. L. Gaertner & J. F. Dovidio, 2000 ) and Communication Accommodation Theory ( C. Shepard, H. Giles, & B. A. LePoire, 2001 ), we examined the role of identity accommodation, supportive communication, and self‐disclosure in predicting relational satisfaction, shared family identity, and group salience in multiracial/ethnic families. Additionally, we analyzed the association between group salience and relational outcomes as well as the moderating roles of multiracial/ethnic identity and marital status. Individuals who have parents from different racial/ethnic groups were invited to complete questionnaires on their family experiences. Participants (N = 139) answered questions about relationships with mothers, fathers, and grandparents. The results of the multilevel modeling analyses are discussed in terms of implications for understanding multiracial/ethnic families and family functioning.     

Violence in the name of god? A framing processes approach to the Islamic State in Iraq and Syria

Since summer 2014, the insurgent group ‘Islamic State in Iraq and Syria’ (ISIS) has become a major concern for international politics and global security due to its rapid territorial gains, violent operations and the propagation of Salafi-jihadist ideology. This study aims to enhance the academic understanding of ISIS by demystifying the ideological reasoning behind its use of violence. It therefore investigates the link between structural factors that served ISIS’s evolution, its ideological outlook and the significance of this ideology to legitimize violent action. As its theoretical basis, the study employs framing processes within the study of social movements. Methodologically, discursive frame analysis serves to explore the relation of ISIS’s ideology to structural events and experiences to better understand how the group justifies violence. Therefore, the study draws on audio speeches and issues of the magazines Dabiq and Dar al-Islam published by ISIS, which are examined on the rhetoric of othering, collective identity and justifying violence. It is argued that ISIS constructs a collective action frame which creates a social reality that bestows the group with a rationale for action. ISIS’s ideology, based on Islamic symbolism, presents an interpretative lens which assigns meaning to the structural environment of ISIS’s emergence. In this context, violence is justified as a necessity to defend Islam and as an obligation for the true Muslim believer. The discussion concludes that ISIS’s ideology legitimizes the very existence of the group and conceals its mundane struggle for power, territory and wealth through reference to divine authority.
