太极拳与瑜伽术的传统意蕴及其文化学阐释

中、印传统体育文化蕴含了东方文明对于处世之道和养身模式的价值追求，作为东方体育文化典型代表的太极拳与瑜伽术，既是修炼身心、运动健身的重要项目，也是人们了解东方体育文化的重要媒介。跨文化比较分析表明，太极拳和瑜伽术在注重身形技法与艺术审美的结合、吐纳导引与意念游动的耦合、修身养性与天人意境的融合等方面具有共性，也有差异，体现出中、印在传统体育文化方面的异同。太极拳和瑜伽术的传承应该做到与时俱进、创新发展，其目标既不是传统竞技搏击术，也不是简单修炼养身术，而是融道德修养与身心修炼为一体的综合性运动项目。     

信息不对称下价格随机的应急数量折扣契约研究

以市场需求和市场价格随机波动的二级供应链为研究对象，寻找其在信息不对称条件下绩效优化的路径。通过显示原理分别构建生产成本和销售成本信息不对称时应急供应链的数量折扣契约模型，得到最优订货量与最佳批发价策略。通过具体的算例加以验证，分析了信息不对称程度对供应链上成员及整个供应链绩效的影响。研究结果表明：当突发事件造成市场价格随机波动和市场需求变化时，供应链上的跟随者能从隐瞒私人信息中获利。但当市场需求增大时，整个供应链绩效受损，反之则反是。这与以往研究在市场需求随机、市场价格固定和信息不对称条件下的结论迥异。     

Leveraging psychological contracts as an HR strategy: The case of software developers

This article studies the management of software developers through the lens of the psychological contract and from the perspectives of employees and employers. Data were gathered through interviews with software developers and their human resources (HR) and/or direct managers in French high-tech companies. Our findings show the crucial role of HR and direct managers who shape a balanced professional psychological contract with developers as a specific HR strategy in order to respond to their job specificities and values. Specific HR practices (nature of the processes, involvement of developers in these processes, credibility of HR/direct managers and career development opportunities) and the working environment contribute to the development of trust and fairness, which form part of the content of the balanced contract.     

What influences the size of child maintenance payments? A register‐based study of maintenance payments in Finland

The aim of this study was to explore how particular economic and demographic factors contribute to the level of the child maintenance payment (CMP) paid by the non‐resident parent. For this study, we used 5‐year longitudinal panel data from years 2009 to 2013 consisting of over 80,000 non‐resident parents from the Finnish Tax Administration and The Finnish Population Register Centre. Results from regression models indicate that the single biggest factor affecting the size of CMPs is the number of dependent children. We found that the non‐resident parent's higher income is associated with higher CMPs and that non‐resident fathers pay on average larger CMPs than non‐resident mothers, even after accounting for differences in income. Unexpectedly, we found that the age of the dependent child did not predict changes in CMPs. This suggests that once formal CMP‐contracts are determined between the parents, they are seldom changed. Our results suggest that some degree of mandatory periodic review for maintenance contracts is worth considering.     

Schematising hospitality: Ai WeiWei’s activist artwork as a form of dark travel

The article provides a holistic appraisal of activist-artist Ai WeiWei’s work. It argues that, despite its topical innovations and evolution, it continues to be informed by narratives of ‘hospitality’ as an experiential form of engagement with variations of otherness (father, migrant, tourist and refugee). Dividing Ai’s artwork into two overlapping phases of development (national and international/global), it considers the artist’s construction of a cosmopolitan identity with uses of ‘technology’ as embodied and communal property. As Ai’s work on the refugee crisis on Lesbos attests, his (dark) artistic cosmopolitan symbolisations use geo-political imaginaries of justice and hospitality in subsequent projects.     

更敦群培旅行文本再解读

更敦群培1934年前往印度、尼泊尔、斯里兰卡等南亚国家游学深造，历时12年之久。在南亚期间，他以文化行者的身份和跨文化视角，撰写了《智游列国漫记——金色的疆域》《锡兰纪行》等极具特色的游记，开创了自成一体的旅行文本。历史上藏族学者对以印度、尼泊尔、斯里兰卡为代表的南亚文化的书写和表达多是对异国形象进行想象建构，而更敦群培的旅行文本则重新审视和考察地理接壤、文化互动地带的印度宗教、民俗文化，消解藏人先验印象中南亚形象的思维定势，重新发现本土文化价值，对根深蒂固的印度宗教文化中心主义发起挑战，反思各种文化偏见和历史成见，不断确立他人文主义思想和文化中立心态。隐匿在旅行文本背后的是人类学家的身份和另一种民族志书写范式。     

Optimal asset allocation for participating contracts with mortality risk under minimum guarantee

Abstract

We investigate an optimal investment problem of participating insurance contracts with mortality risk under minimum guarantee. The insurer aims to maximize the expected utility of the terminal payoff. Due to its piecewise payoff structure, this optimization problem is a non-concave utility maximization problem. We adopt a concavification technique and a Lagrange dual method to solve the problem and derive the representations of the optimal wealth process and trading strategies. We also carry out some numerical analysis to show how the portfolio insurance constraint impacts the optimal terminal wealth.     

Reinvigorating the social contract and strengthening social cohesion: Social protection responses to COVID-19

The COVID-19 pandemic has exposed the vulnerability of those who are inadequately covered by social protection in more and less developed countries alike, and has exacerbated the fragility of a social contract that was already under strain in many countries. A weak social contract in the context of an exceptional crisis poses a very real risk to social cohesion. Nevertheless, many States have reasserted themselves as the guarantor of rights by protecting public health and incomes. By sustaining these measures, economic recovery will be supported which will help minimize risks that may weaken social cohesion. However, this is a fast-moving, inherently unstable and protracted crisis. Social protection stands at a critical juncture. Decisive policy action will be required to strengthen social protection systems, including floors, as one of the cornerstones of a reinvigorated social contract.     

公司高级管理人员解雇保护问题研究——以《劳动合同法》第48条为视角

在我国,由于劳动法和公司法内容的冲突以及公司高级管理人员在现有劳动法语境下身份的特殊性,导致了不同法院对于劳动合同违法解除后劳动合同继续履行与否的判决并不一致。高级管理人员并不完全具有劳动法上劳动者人格和经济上的从属性,因而其不应该获得完全的与普通劳动者相同的倾斜保护。而且,高级管理人员被解聘后,因为岗位的重要性,公司往往会迅速找人代替;由于岗位数量稀缺性和要求的专业性,高级管理人员要求恢复原岗位的要求在实践中难以满足。因此,法院在适用《劳动合同法》第48条时,不应支持被解除职务的高管的复职请求,而应采用其他救济方式。     

基于多目标加权灰靶决策模型的节能服务公司选择研究

用能方对节能服务公司（Energy Service Company，ESCO）的选择关系到合同能源管理（Energy Performance Contracting，EPC）能否顺利实施。从用能方的角度，采用灰色系统理论中的多目标加权灰靶决策模型，对存在多决策目标的ESCO选择问题进行研究。通过层次分析法确定ESCO的11个决策目标的决策权数，根据综合效果测度值的比较，最终实现最优对策的选择。本文为用能方的ESCO选择问题提供了一种新的思路。
