信用问题的制度基础分析

信用制度是指信用规范与规则的制度化,它是由社会认可的非正式约束、国家规定的正式约束和实施机制所构成的。尽管从各国的信用制度实践情况来看,诱致性制度变迁和强制性制度变迁似乎各有轨迹,但总体上,信用制度都遵循共同的变迁轨迹,只不过由于各国历史和经济基础的不同,在每个国家的不同历史阶段发展状况也就有所侧重。信用制度也有其供给和需求,并且在社会领域中也发挥着重要的作用,对其研究不仅在理论上极其必要,在我国实践领域也具有极强的现实意义。     

Is it worth it? Linking perceived high-performance work systems and emotional exhaustion: The mediating role of job demands and job resources

The present study utilizes the job demands–resources model and examines the effects of employees’ perceptions of high-performance work systems (HPWS) on emotional exhaustion. For the needs of this study, structural equation modeling (SEM) was used on a sample of 343 frontline employees in a Greek manufacturing company. The findings do not support the critical arguments regarding HPWS, which suggest that these systems lead to work intensification and emotional exhaustion through increased job demands. In contrast, HPWS was positively related to job resources, although no support was found for a direct and negative relationship with emotional exhaustion. Last but not least, this study calculates HPWS as both a system and bundles of practices and provides useful insights regarding the differences between the two different measurement methods. Finally, theoretical and managerial implications are drawn for improving our understanding of how HPWS influences job demands and resources and employees’ emotional exhaustion.     

Women Underrepresentation in R&I: A Sector Program Assessment of the Contribution of Gender Equality Policies in Research and Innovation

Despite decades of efforts to achieve gender equality in research and innovation (R&I), all EU member states still face remarkable difficulties in driving forward the development of their innovation system while at the same time improving gender equality by using all the available research potential. In this paper we focus on the development of the share of women researchers in four national innovation systems, i.e. in Austria, Denmark, Hungary and Spain in the time period 2005-2015. The four selected cases represent countries with significant differences in their innovation capacity, gender regimes and progress of gender equality in R&I. A qualitative comparative analysis (QCA) is carried out to conduct a sector program evaluation based on statistical data and qualitative studies to understand the dynamic development of the proportion of women researchers. The study aims to provide insights into the aggregated gender equality interventions and policies implemented in the four countries studied and their contributions to the development of the proportion of women scientists at the structural level. The analysis reveals that the development of the share of women researchers during the studied period has been particularly influenced by contextual factors, namely the relative size of the business enterprise sector and the share of women among holders of tertiary education. While this is the case, it is found that gender equality interventions need to be more widespread and more effectively designed to be a strong contributing factor to an increasing representation of women in R&I.     

Resolving complex community problems: Applying collective leadership and Kotter's change model to wicked problems within social system networks

How does collective leadership within social networks resolve chronic and complex problems common to communities? Unfortunately, sometimes it does not, but when it does, the outcome may be truly extraordinary. We use a case study approach to explain how one Midwest community within the USA applied collective leadership within a community network to reduce teen births. It took ten years of what many identified as provocative media campaigns and comprehensive sex education programs to reduce teen births by 65%, significantly exceeding the stated goal. Using Kotter's change model as a backdrop, powerful strategies and provocative creativity reveal courageous leadership within a social network of diverse people and organizations focused on improving the social well being of their community.     

The competing risks analysis for parallel and series systems using Type-II progressive censoring

Abstract

Recently, the study of the lifetime of systems in reliability and survival analysis in the presence of several causes of failure (competing risks) has attracted attention in the literature. In this paper, series and parallel systems with exponential lifetime for each item of the system are considered. Several causes of failure independently affect lifetime distributions and observations of failure times of the systems are considered under progressive Type-II censored scheme. For series systems, the maximum likelihood estimates of parameters are computed and confidence intervals for parameters of the model are obtained using Fisher information matrix. For parallel systems, the generalized EM algorithm which uses the Newton-Raphson algorithm inside the EM algorithm is used to compute the maximum likelihood estimates of parameters. Also, the standard errors of the maximum likelihood estimates are computed by using the supplemented EM algorithm. The simulation study confirms the good performance of the introduced approach.     

A sampling plan for one-shot systems considering destructive inspection

Abstract

The paper is concerned with an acceptance sampling problem under destructive inspections for one-shot systems. The systems may fail at random times while they are operating (as the systems are considered to be operating when storage begins), and these failures can only be identified by inspection. Thus, n samples are randomly selected from N one-shot systems for periodic destructive inspection. After storage time T, the N systems are replaced if the number of working systems is less than a pre-specified threshold k. The primary purpose of this study is to determine the optimal number of samples n*, extracted from the N for destructive detection and the optimal acceptance number k*, in the sample under the constraint of the system interval availability, to minimize the expected cost rate. Numerical experiments are studied to investigate the effect of the parameters in sampling inspection on the optimal solutions.     

系统工程思想视角下三产融合振兴民族村落的路径——基于贵州批林村的经验探索

农村三产融合是一个由多种要素组成的系统工程。研究基于对贵州花溪区批林村的田野调查,发现：目前批林村对三产融合进行探索的电农融合、工农融合和文旅融合项目在实施过程中存在一些阻碍,具体包括发展资金较为匮乏,基础设施难以建设;技术渗透能力不强,新型产业难以发展;村落建设人才短缺,项目规划难以推进;三产融合程度较浅,产业增值难以实现;利益联结机制欠缺,农民利益难以保障等。针对批林村现实存在的典型问题,基于系统工程思想的指导,研究为三产融合振兴民族村落构建出以下发展路径：一是完善系统顶层设计,统筹三产融合发展思路;二是精准定位发展要素,抓住三产融合关键环节;三是合理布局结构关系,优化三产融合整体功能;四是创新融合发展方式,实现三产融合系统升级;五是加强后续保障机制,促进三产融合稳步运营。

The Synthetic Situation: Interactionism for a Global World

Presented as the Distinguished Lecture at the annual meeting of the Society for the Study of Symbolic Interaction in Boston, Massachusetts, on August 1, 2008, this article rethinks central assumptions of the interaction order as conceptualized by Goffman and others with respect to global domains of activity. 1 It proposes two new concepts, that of the synthetic situation and that of time transactions. Synthetic situations are situations that include electronically transmitted on‐screen projections that add informational depth and new response requirements to the “ecological huddle” ( Goffman 1964 :135) of the natural situation. Global situations invariably include such components; we also find that temporal forms of integration may substitute for joint territoriality of copresence in the natural situation. Based on research on global currency trading and other empirical examples, I identify four types of synthetic situations and describe the synthetic situation's informational character, its ontological fluidity, and the phenomenon that synthetic situations may become role‐others for participants. I outline the response system of synthetic situations, sketching out the concepts of response presence and its implications in this context as well as the importance of embodiment. I also discuss time transactions and the idea of fatefulness as a symbolic charge linked to the synthetic components of the situation.
