转变经济发展方式的矛盾、难点与出路

尽管转变经济发展方式在表达层面上已经形成共识,但在具体行动时却困难重重.早在"九五"计划时,我们就已经提出了实现经济增长方式的根本转变,但至今是"久推难转".干部政绩考核和选拔晋升制度的偏离、财政税收体制的缺陷,以及资源价格机制的扭曲这三个方面的原因阻碍了经济发展方式的转变.根本出路在于继续深化改革,切实转变政府职能,创新有利于经济发展方式转变的体制机制.     

Donating Time or Money? The Effects of Religiosity and Social Capital on Civic Engagement in Qatar

Few studies have examined the role of religiosity and social capital on civic engagement in the context of a Muslim country. In this paper, we explore the impact of religiosity and social capital on charitable donations and volunteerism in Qatar. Drawing on a nationally representative survey from Qatar, we consider various attitudinal and behavioral measures for capturing religiosity and social capital. The results indicate that, even after controlling for a wide range of demographic variables, behavioral measures have a stronger effect than attitudes. Individuals who regularly perform daily prayers are more likely to donate than those individuals who simply describe themselves as religious. Similarly, individuals who are more active in their neighborhood engagement are more likely to volunteer than those who merely report high levels of social trust. These results suggest that when it comes to the relationship between religiosity, social capital and civic engagement, individual behavior is much more predictive than attitudes alone. We also find that even in the case of Qatar, where citizen wealth has rapidly increased in the last few decades, there is little evidence of substitution effects: citizens do not appear to trade-off or substitute between time and money. Instead, more religious and active citizens are likely to do both.     

Implementing the right project structure to achieve coopetitive innovation projects

This research focuses on the project structure used by coopetitors to achieve common innovation projects. Scholars have recently identified an original but complex project structure that they call the Coopetitive Project Team (CPT). However, other project structures can also be implemented by coopetitors to achieve innovation. Therefore, we address the following question: for which types of innovation projects is CPT appropriate? We argue that coopetitors need to use CPT for high-risk and high-cost projects when the aim is to develop radical innovation. CPT allows coopetitors not only to develop innovation capabilities through close resource and knowledge sharing but also to manage the risk of opportunism. Conversely, coopetitors should use another project structure, Separated Project Teams (SPTs), for low-cost and low-risk projects when the aim is to develop incremental innovation. The SPT design allows coopetitors both to achieve the goal of the project and to minimize the risk of opportunism. To confirm our assumptions, we studied the project portfolios of Airbus and Thales, two firms in the space satellite industry. Our findings confirm that coopetitors should implement CPTs to handle innovation projects that are costly, risky and highly innovative. CPTs permit the sharing of knowledge and the management of high opportunism risk, both of which are necessary to achieve radical innovation. Conversely, coopetitors rely on SPTs for low-cost projects that require a low degree of knowledge sharing, thus avoiding the risk of opportunism in achieving their incremental innovation objectives.     

Adjexpectile风险测度的性质、优化及资产配置的应用

金融风险的度量和识别是风险管理的重要内容,常用的风险度量工具是标准差、VaR、ES,但存在很多缺陷,expectile的提出弥补了这些不足,在理论界得到广泛的讨论和应用。本文扩展了expectile进行资产配置,提出Adjexpectile的概念,并讨论和分析了Adjexpectile的一致性风险度量、随机占优性、凸性,与标准差、VaR、shortfall的关系,风险贡献及风险分解的性质。通过对六个资产指数：上证国债指数、上证企业债指数、上证180指数、深圳100指数、深成长40p指数和黄金现货指数的复合周收益率数据进行组合优化配置,发现Adjexpectile在非对称性收益数据、组合前沿、风险分散方面具有一定的优越性。     

Techniques of Death: Buddhist Practice,Femininity and Self-Cultivation at the Last Stage of Life in Vietnam

This article explores how death is conceptualised by elderly lay Buddhist women in H? Chí Minh City (Vietnam). It explores the traits of a ‘good death’ which elderly laywomen wish to experience, and their dedicated practice of Buddhism to prepare themselves for a peaceful end stage of life. This article contends that, in fact, women’s perceptions of death speak to their desires to live a life with dignity and retain their full personhood and nurturing femininity which they have embodied throughout their adult lives even until their last moments. They pursue devotional practices to train their body and mind in order to prepare themselves for the critical moment of dying, believing that these self-cultivating practices will enable them to transcend physical suffering and mental confusion, and immediately move on to the next, better life.     

高校贫困生AHP-CBR分级认定模型建构

准确认定贫困学生资格是高校合理、公平分配资助资源的先决条件.本文利用层次分析法(AHP)与案例推理(CBR)原理建构高校贫困生分级认定模型,构造了贫困生案例属性层次模型;采用向量定义法,给出了案例库和贫困生分级认定问题的形式化描述;研究了以案例检索为基础的贫困生分级认定算法.模型有效性测试结果表明:案例库中案例数量大于1094条记录后,案例检索结果具有稳定的匹配案例相似度;对目标案例的求解结果与原认定结论进行显著性差异检验,Z检验统计量计算结果均小于1.96,二者无显著性差异,表明模型计算结果是有效的.     

Identifying key factors in momentum in basketball games

Momentum as elaborated under a recent novel definition has been shown quantitatively to have a significant impact on basketball game outcomes. This paper makes two contributions to the analytical literature on sports momentum: (1) two aspects of the new definition are operationalized so that its practicality becomes evident; and (2) through a dimension-reduction technique (elastic net), key factors associated with momentum are identified. Both technical variables such as field goals, assists, rebounds, etc. and environmental variables such as the spectator attendance rate and player salary dispersion are considered, and the potential for useful real-time analyzes is illustrated.

"一带一路"背景下中国边疆形象构建的历史基础与文化战略意义

自古以来,“边疆”作为中国对外交流的关口,具有不可取代的战略意义。古时,在“一点四方”统治观念下,“边疆”具有区别于王朝国家核心区的文化地理内涵,通过“边疆”走向欧洲、非洲的丝绸、瓷器、茶叶开启了西方人对东方国度乌托邦式的想象。近代,随着王朝国家的衰落和西方启蒙运动自我批判的觉醒,“边疆”又成为“东方地狱”中一抹神秘的色彩,一块未经发掘的处女地。20世纪90年代,自中国将“和平崛起“作为对外交流的叙述话语以来,“边疆”又被西方冠以落后、分裂、暴力的形象,意图通过充满意识形态的“人权”倡导和模糊的民族国家概念来肢解中华民族。中国边疆何以在不同的历史时期具有“性格迥异”的面孔？新时期,“一带一路”倡议的提出为边疆形象的塑造和传播提供了更加丰富的场域和资本。而边疆形象的合理建构也对“一带一路”倡议的整体布局、中国国际话语权的提升、中国形象的正确定位、与邻国的政治经济交往以及边疆地区自身的发展稳定具有重要的战略意义。     

The effect of tapering on the semiparametric estimators for nonstationary long memory processes

In this paper, we study, by a Monte Carlo simulation, the effect of the order p of “Zhurbenko-Kolmogorov” taper on the asymptotic properties of semiparametric estimators. We show that p  =  [d + 1/2] + 1 gives the smallest variances and mean squared errors. These properties depend also on the truncation parameter m. Moreover, we study the impact of the short-memory components on the bias and variances of these estimators. We finally carry out an empirical application by using four monthly seasonally adjusted logarithm Consumer Price Index series.
