Capturing the broader picture of value co-creation management

The interactional, interdependent, and dynamic nature of value co-creation has made value management in business relationships a particularly challenging issue for both academicians and practitioners. In addition, studies on this topic have mostly focused on managing value co-creation in isolation from the wider relational context without completely capturing the influence of other value processes on value co-creation. This paper examines the broader picture of value co-creation management by providing a model based on interlinked value processes, namely, value communication, value appropriation, value measurement, and value representation. We adopted a qualitative approach based on 86 interviews with managers of both customer and supplier companies, which operated in different industries. Results showed that the management of value co-creation implies considering complex patterns of interconnections with other value processes. In particular, the study will shed light on the centrality of value appropriation to co-create value and on the importance of value representation to coordinate ideas and enable future co-creation opportunities.     

A new financial stress index model based on support vector regression and control chart

Financial stress index (FSI) is considered to be an important risk management tool to quantify financial vulnerabilities. This paper proposes a new framework based on a hybrid classifier model that integrates rough set theory (RST), FSI, support vector regression (SVR) and a control chart to identify stressed periods. First, the RST method is applied to select variables. The outputs are used as input data for FSI–SVR computation. Empirical analysis is conducted based on monthly FSI of the Federal Reserve Bank of Saint Louis from January 1992 to June 2011. A comparison study is performed between FSI based on the principal component analysis and FSI–SVR. A control chart based on FSI–SVR and extreme value theory is proposed to identify the extremely stressed periods. Our approach identified different stressed periods including internet bubble, subprime crisis and actual financial stress episodes, along with the calmest periods, agreeing with those given by Federal Reserve System reports.     

习近平总书记关于高校体育工作重要论述的逻辑意蕴与实践路径

“一带一路”沿线国家设施联通对贸易利益的影响

以全球价值链（GVC）参与为视角，基于2005—2015年40个“一带一路”沿线国家与我国的增加值贸易数据，采用静态面板固定效应模型实证分析交通基础设施和通信基础设施对“一带一路”沿线国家贸易利益的影响。结果发现，加强交通和通信基础设施建设有利于提高一国出口中所包含的国内增加值，增进该国的贸易利益。作用机制研究表明，交通基础设施和通信基础设施都能够通过降低贸易成本促进贸易利益的提升，其中通信基础设施还能够通过提高贸易的时间效率对贸易利益产生积极影响。因此，“一带一路”沿线国家应以设施联通为依托，加强本国的交通和通信基础设施建设，把握参与国际生产分工的主动权，以实现共同发展繁荣。     

基于信号博弈的卖方欺诈行为分析

本文主要基于信号博弈的卖方欺诈行为进行研究，假设拍卖中可能存在欺诈型和诚实型两种卖家，其中欺诈行为有概率发生在第二价格拍卖中：欺诈型卖方冒充竞拍者递交仅次于最高价的报价从而获得额外收益。两种卖家根据各自效用选择拍卖形式：第一价格或者第二价格。而竞买者将卖者的选择作为信号，更新对卖方类型的判断，然后制定报价策略。这是一个买卖方信号交叉影响的过程。考虑到拍卖过程中买方价值相关性，本文在建立模型中参考了关联价值原理。针对该模型进行分析，得出了不同情况下的买卖方策略，并且研究了买方报价、买方判断、卖方收益三者之间的关系。文中利用贝叶斯公式对双方的策略选择问题进行预测，与单纯的概率分布方法相比，更具实践价值。     

Assessing the market values of soccer players – a robust analysis of data from German 1. and 2. Bundesliga

The paper examines to what extent a player's market value depends on his skills. Therefore, a data set covering 28 performance measures and the market values of about 493 players from 1. and 2. German Bundesliga is analysed. Applying robust analysis techniques, we are able to robustly estimate market values of soccer players. The results show (1) that there are significantly underrated and overrated players and (2) that a player's affiliation to a certain team may contribute to his market value. We conclude that a club's reputation affects the market values of its players and that star players are in tendency overrated.     

论“莱西会议精神”对新时期全面深化农村基层党组织建设的价值和意义

农村基层党组织是党在农村的神经末梢,也是党的路线、方针、政策的"终端"推动者和实践者。现阶段农村党组织建设面临新兴组织不断涌现与党组织作用削弱的不适应,"权力和资源缺失"与服务刚性增强的不适应,村民自治进一步发展与群众政治参与欠充分的不适应,群众诉求多样化与满足渠道单一的不适应,部分党员党性不强、意识淡化与始终保持先进性的要求不适应等问题。在加强以党支部为核心的农村基层组织建设的"莱西会议精神"指导下,全面深化农村基层党组织建设:思想上高度认识是前提,加强支部建设是核心,坚持法治、完善村民自治是重点,紧扣服务、创新制度是关键,统筹协调、综合配套是保障。     

基于人力资源管理价值链视角的“用工荒”现象分析

本文基于人力资源管理价值链的视角，分析了政府和企业在农民工这一特殊人力资源类型的价值创造、价值评价和价值分配的三个环节管理中存在的问题。这些问题最终导致了＂用工荒＂现象的产生。政府层面存在的主要问题有：在价值评创造环节中，缺乏对低端劳动力群体的规划、建立统一的劳动力市场和对农民工技能培训经费的投入不足；在价值评价环节，缺乏对技能人才的评价机制；在价值分配环节，对农民工利益保障的立法不完善且执法不严。企业层面存在的主要问题有：在价值创造环节，只重使用，不重培养；在价值评价环节，缺乏多种评价手段；在价值分配环节，企业发放给农民工的薪酬福利低，针对以上问题，从政府和企业两个层面，提出了相应的解决对策。     

Beyond tail median and conditional tail expectation: Extreme risk estimation using tail Lp-optimization

The conditional tail expectation (CTE) is an indicator of tail behavior that takes into account both the frequency and magnitude of a tail event. However, the asymptotic normality of its empirical estimator requires that the underlying distribution possess a finite variance; this can be a strong restriction in actuarial and financial applications. A valuable alternative is the median shortfall (MS), although it only gives information about the frequency of a tail event. We construct a class of tail L^p-medians encompassing the MS and CTE. For p in (1,2), a tail L^p-median depends on both the frequency and magnitude of tail events, and its empirical estimator is, within the range of the data, asymptotically normal under a condition weaker than a finite variance. We extrapolate this estimator and another technique to extreme levels using the heavy-tailed framework. The estimators are showcased on a simulation study and on real fire insurance data.     

从社会文化价值因素和社会结构看中国近代科学落后的原因——李约瑟难题再探

半个世纪以来 ,李约瑟博士提出的难题 ,引起了我国学者的热烈讨论。本文仅从中国社会文化价值因素和社会结构的角度对中国近代科学落后的原因进行再探讨。中国近代社会是封建专制、封闭禁锢的社会结构 ,其特征是高度集权、封闭禁锢、以人治代替法制 ,这种社会结构形成了一种内向的、稳定的、隔绝的文化机制。因此 ,阻碍了中国近代科学的发展。
