社会组织与政府协同的进化博弈分析

社会组织作为协同治理多元化主体中的重要一员,在协同治理中发挥着不可替代的作用,但为何在社会组织协同政府治理已成共识的前提下双方协同尚处于低水平现状,现有研究缺乏解释力.本文运用进化博弈论理论,构建社会组织与政府协同的非对称进化博弈模型,从理论上分析判定影响双方协同策略选择的关键因素.研究表明:协同成本与协同额外收益的分配直接影响社会组织与政府协同策略的选择.因此,要推进我国社会组织与政府协同关系的深入,应充分发挥政府部门在协同中的主导作用、不断降低协同所产生的成本并优化协同额外收益的分配.     

基于整体网模型的区域产业结构的升级比较与动态演变——以东部沿海综合经济区为例

本文从关系的视角研究区域产业结构升级以及变化,用社会网络的方法,针对核心产业、产业升级、产业结构演变以及影响产业结构的因素,以东部沿海经济区为例进行实证研究.对于核心产业,使用产业中心性、产业影响力以及结构洞与中间人评价指标,运用模糊数学与向量夹角余弦组合评价模型来评价核心产业.对于产业升级,使用可视化与对比分析来对不同年份的核心产业进行评估,得出东部沿海经济区2007年至2012年产业升级幅度较大,核心产业变化较大.对于产业结构,使用块模型分析,得出结果为东部沿海经济区可以分为四大板块,不同年份产业的结构之间联系有变化.对影响产业结构的因素使用QAP相关分析以及QAP回归分析,QAP方法解决了一般统计方法不能处理的关系数据回归,得出了东部沿海经济区的产业结构受产业在经济区外的流出、原先的产业结构以及我国三大产业划分的影响.     

Nonparametric Estimation of the Number of Drug Users in Hong Kong Using Repeated Multiple Lists

We update a previous approach to the estimation of the size of an open population when there are multiple lists at each time point. Our motivation is 35 years of longitudinal data on the detection of drug users by the Central Registry of Drug Abuse in Hong Kong. We develop a two‐stage smoothing spline approach. This gives a flexible and easily implemented alternative to the previous method which was based on kernel smoothing. The new method retains the property of reducing the variability of the individual estimates at each time point. We evaluate the new method by means of a simulation study that includes an examination of the effects of variable selection. The new method is then applied to data collected by the Central Registry of Drug Abuse. The parameter estimates obtained are compared with the well known Jolly–Seber estimates based on single capture methods.     

Testing Hypotheses in Nonparametric Models of Production

Data envelopment analysis (DEA) and free disposal hull (FDH) estimators are widely used to estimate efficiency of production. Practitioners use DEA estimators far more frequently than FDH estimators, implicitly assuming that production sets are convex. Moreover, use of the constant returns to scale (CRS) version of the DEA estimator requires an assumption of CRS. Although bootstrap methods have been developed for making inference about the efficiencies of individual units, until now no methods exist for making consistent inference about differences in mean efficiency across groups of producers or for testing hypotheses about model structure such as returns to scale or convexity of the production set. We use central limit theorem results from our previous work to develop additional theoretical results permitting consistent tests of model structure and provide Monte Carlo evidence on the performance of the tests in terms of size and power. In addition, the variable returns to scale version of the DEA estimator is proved to attain the faster convergence rate of the CRS-DEA estimator under CRS. Using a sample of U.S. commercial banks, we test and reject convexity of the production set, calling into question results from numerous banking studies that have imposed convexity assumptions.

阅读毛泽东文本：认识论问题

毛泽东的认识论并非严格意义上的经验主义,而是经验主义和理性主义的混合物。研究毛泽东的思想需要理论干预,应将其文本看作理论推演的实体,并关注文本中现有的理论主张、合乎逻辑的假设和建构方式及其相互间的关系以及这些关系的一致性和连贯性程度。     

论元散曲中的青楼词兼论元代妓女特点

通过比较元散曲中妓女所作之曲与男性所作青楼之曲,论证了前者更真实地反映了她们的从良愿望、凸现了她们的文学才华,审美品位也更高尚.论述了为何元妓人数倍多于唐宋妓,而有文学才华的却最少.从元代重武轻文、统治者不通文墨、元妓普遍文化水平低下三方面探索了原因.以<青楼集>等文献和元杂剧妓女戏为据,论证了元妓比唐宋妓更有自觉争取人权的抗争意识,并达到前所未有的高度.     

Ordering competition: the interactional accomplishment of the sale of art and antiques at auction

Auctions provide an institutional solution to a social problem; they enable the legitimate pricing and exchange of goods where those goods are of uncertain value. In turn, auctions raise a number of social and organizational issues that are resolved within the interaction that arise in sales by auction. In this paper, we examine sales of fine art, antiques and objets d'art and explore the ways in which auctioneers mediate competition between buyers and establish a value for goods. In particular, we explore how bids are elicited, co-ordinated and revealed so as to rapidly escalate the price of goods in a transparent manner that enables the legitimate valuation and exchange of goods. In directing attention towards the significance of the social interaction, including talk, visual and material conduct, the paper contributes to the growing corpus of ethnographic studies of markets. It suggests that to understand the operation of markets and their outcomes, and to unpack issues of agency, trust and practice, we need to place the 'interaction order' at the heart of analytic agenda.     

Urge to Gamble in Problem Gamblers Exposed to a Casino Environment

Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure. Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue exposure should be studied further as a potential tool in the treatment of problem gambling.
