民族、婚姻、伙有共耕与上帝:基督教嵌入藏区傈僳族社会之阐释——以滇西北德钦县霞若乡为例

基于对云南西北部一个傈僳族乡村全体傈僳族自20世纪90年代以来改信基督教的过程进行考察,指出傈僳族信仰基督教是身处碎片化、原子化社会结构中的族群面对周边民族的歧视与物质资料和人口再生产的重重压力下作出的无奈选择,提出“婚姻一家庭一土地一民族”是基督教在傈僳族社会传播的网络,这一模式可以解释为什么基督教在傈僳族社会传播呈现出民族性特征,区别于基督教在汉族乡村社会传播呈现出的宗族性特征.     

The influence of acculturation level and family relationships on quality of life among U.S. Chinese older adults

ABSTRACT

The present study examined the influence of acculturation level and family relationships (i.e., positive family support and negative family strain) on quality of life (QOL), using the data from the Population Study of ChINese Elderly (PINE) in Chicago (N = 3159). Controlling for sociodemographic variables and health status, it was found that individuals’ acculturation level and positive family support were positively related to QOL, whereas negative family strain was negatively associated with QOL. More importantly, higher acculturation levels were associated with increased protective effects of positive family support and reduced risk effects of negative family strain on QOL among U.S. Chinese older adults.     

工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.

Approximation strategy-proof mechanisms for obnoxious facility location on a line

In the facility location game on a line, there are some agents who have fixed locations on the line where an obnoxious facility will be placed. The objective is to maximize the social welfare, e.g., the sum of distances from the facility to all agents. On collecting location information, agents may misreport the locations so as to stay far away from the obnoxious facility. In this paper, strategy-proof mechanisms are designed and the approximation ratio is used to measure the performances of the strategy-proof mechanisms. Two objective functions, maximizing the sum of squares of distances (maxSOS) and maximizing the sum of distances (maxSum), have been considered. For maxSOS, a randomized 5/3-approximated strategy-proof mechanism is proposed, and the lower bound of the approximation ratio is proved to be at least 1.042. For maxSum, the lower bound of the approximation ratio of the randomized strategy-proof mechanism is proved to be 1.077. Moreover, a general model is considered that each agent may have multiple locations on the line. For the objective functions maxSum and maxSOS, both deterministic and randomized strategy-proof mechanisms are investigated, and the deterministic mechanisms are shown to be best possible.     

大学生返乡创业生态系统：目标、要素、机理和对策*

创业生态系统从生态系统的视角揭示了创业生态中创业主体、创业要素、创业环境以及各要素之间的相互作用。创业生态系统是一个复杂的自适应系统，其具有复杂的自适应系统的各项特征，从系统的角度来讲，其具有系统的目标、要素、运行机理和系统边界。本文以大学生返乡创业生态系统为例，从系统目标、系统要素和系统的运行机理三个方面立体剖析了创业生态系统的内涵和外延。同时，对大学生返乡创业生态系统的目标设定、大学生返乡创业生态系统各要素的构成以及大学生创业生态系统的运行机理进行了分析，对强化大学生返乡创业生态系统的构建提出了对策建议，为促进大学生返乡创业和乡村振兴提供参考。     

中国人口学科国际化水平及其影响因素

国际化是学科成熟与发展的一个重要指标。但是作为世界人口第一大国,中国人口学科的国际化并没有发展到一个相对应的水平。在界定了学科国际化概念的基础上,借助问卷调查数据来分析中国人口学科国际化的现状,探讨中国人口科学继续与国际学界融合所面临的困难及其主要原因。结果表明,中国人口学的国际化明显处于不断萎缩的态势,其直接动因和深层次缘由分别是整个人口学界的国际化意识与能力的减弱,以及人口学科文化与制度本身存在的缺陷。加强国际化的学科文化建设与建立相配套的学科制度是提高中国人口学科国际化水平的重要途径。     

区域经济一体化的法律治理

我国当前区域经济一体化的法律治理机制,有区域行政协议、区域性组织、区域协作立法、区域行政规划和区域行政指导五种。在国家与社会维度上,区域经济一体化的法律治理是一个行为法问题,是国家对市场经济的宏观调控,其依据是宪法第15条,内容的合法性在于遵循区域平等原则,程序的合法性在于公众参与。其中,区域平等源自公民个人的平等权,既约束国家对不同区域公民的公权力行为,又约束不同区域政府机关间的行为;公众参与在区域治理中具有更丰富的特点,既是促进区域平等的途径,又是在行政内部机制失灵时推动制度运行的动力机制。在国家组织系统内部,区域经济一体化的法律治理是一个组织法问题。其中,区域行政指导和区域行政规划,实践了宪法和组织法上规定的领导,蕴含着领导事项、领导方式和领导区域等要素。区域经济一体化中,人大的作用应在各方支持下按照政府治理的要求予以加强,以增强区域经济一体化的民意基础。各地开发区管委会的设立并非都具合法性,其职权中不得包括行政强制措施权、冻结和拍卖权以及有关人身自由的处罚权。行政区政府机关之间的主要合作机制是区域行政协议。它是宪法上民主集中制原则的体现和对市场主体的尊重,它对缔约主体的约束力有赖于缔约各方的诚实信用。     

A narrative inquiry into the identity formation of Chinese doctoral students in relation to study abroad

The present study explores a topic which has been under-studied to date, namely the identity formation of Chinese PhD students in relation to study abroad. Underpinned by Giddens’ ‘reflexive project of the self’, which privileges agency and reflexivity, and using a narrative inquiry approach, it presents four students ‘stories’ collected through semi-structured interviews and focus group discussions. In building a picture of the ways in which students’ self-identity is shaped by and shapes their experience of study abroad, the stories illustrate individual agency, motivation, self-determination and reflexivity. In doing so, they challenge the essentialised view of Chinese students as a homogeneous and sometimes problematic group and point to implications for action by the host institutions.
