90年代以来甘肃省人力资本水平空间差异探讨

随着知识生产与创造的高素质科技劳动者逐步成为一个地区能否吸引现代经济活动的关键．人力资本在区域经济增长中越来越受到人们的关注。文章从时间和空间两方面入手．探讨了90年代以来甘肃省人力资本水平的空间差异及其变化状况。结果表明：甘肃省区域人力资本水平得到明显提高。人力资本水平的地理空间格局由1990年的中部高、西北和东南部低的“凸”字形分布渐渐转向2000年的中西北部高。而东南部低的倾斜式分布：区域人力资本水平差异仍然较大,其增长幅度的区域差异也十分显著。文章还就人力资本差异的形成机制进行了探讨,并提出了促使区域人力资本可持续发展的相关建议和对策。     

当代青年择偶的收入观——郎才女貌悖论

采用2002年中国住户调查数据,本文对当前我国婚姻市场的择偶标准进行了实证研究。在传统社会,高收入的男性和专职于家庭事务的女性被认为是完美的结婚组合(郎才女貌),因此当时的择偶标准体现为收入上的异质性。而本文通过实证研究发现,当前收入水平相当的男女更可能结为夫妻。现在与过去择偶标准的不同导致了郎才女貌悖论的出现。最后,本文阐述了婚介机构的重要性。     

Modern Traditionalism: Consanguineous Marriage in Qatar

Consanguineous marriage, or matrimony between biological relatives, is commonplace and on the rise in Qatar, an ethnically heterogeneous Middle Eastern country. Previous studies have demonstrated that modernization often reduces traditional forms of marriage, such as arranged and consanguineous matrimony. Qatar's rapid modernization, however, has coincided with increased rates of endogamy. In this article, the authors examine the social processes that shape normative consanguineous marriage formation and progression in Qatar. On the basis of in‐depth interviews (n = 35) with men and women engaged or married to a cousin, they detail the categorical schemas that lead to consanguineous matrimony: reservation, joking, filtering, engagement, and courtship. In describing these social exchanges, the authors illustrate 2 key features embedded within them: (a) their distinct tempo and (b) how participants frame their experiences using discourses of romantic love. Reflecting larger cultural practices and attitudes in Qatar, the authors found an amalgam of contemporary and conventional that they label modern traditionalism.     

Residential mobility and the spatial dispersion of personal networks: Effects on social support

Using a representative national sample of personal networks, this article explores how the spatial dispersion of networks, residential mobility and social support are linked. Three issues will be addressed here. Firstly, how is the spatial dispersion of personal networks related to individuals’ social characteristics, network composition and residential mobility? Secondly, how do the spatial dispersion of networks, residential mobility and their combined effect influence the number and (thirdly) the structure of emotional support ties? Results showed that the extent of the support was affected neither by the geographical distribution of the networks nor by residential mobility. Living far from one's birthplace, however, exerted two distinct, and opposite effects on the support network structure. On the one hand, mobility led to high spatial dispersion of personal contacts, which in turn favored a sparsely knit network centered around the mobile individual. On the other hand, by controlling for the effect of distance between the contacts, we found that individuals that cited long-distance ties tended to be part of more transitive support networks than those that cited local ties. We interpreted the latter effect as evidence that transitive ties may survive greater spatial distances than intransitive ones. These findings are discussed in view of spatial mobility and social network research.     

Norms,status and the dynamics of advice networks: A case study

The issue of the influence of norms on behavior is as old as sociology itself. This paper explores the effect of normative homophily (i.e. “sharing the same normative choices”) on the evolution of the advice network among lay judges in a courthouse. 0020 and 0025 social exchange theory suggests that members select advisors based on the status of the advisor. Additional research shows that members of an organization use similarities with others in ascribed, achieved or inherited characteristics, as well as other kinds of ties, to mitigate the potentially negative effects of this strong status rule. We elaborate and test these theories using data on advisor choice in the Commercial Court of Paris. We use a jurisprudential case about unfair competition (material and “moral” damages), a case that we submitted to all the judges of this court, to test the effect of normative homophily on the selection of advisors, controlling for status effects. Normative homophily is measured by the extent to which two judges are equally “punitive” in awarding damages to plaintiffs. Statistical analyses combine longitudinal advice network data collected among the judges with their normative dispositions. Contrary to what could be expected from conventional sociological theories, we find no pure effect of normative homophily on the choice of advisors. In this case, therefore, sharing the same norms and values does not have, by itself, a mitigating effect and does not contribute to the evolution of the network. We argue that status effects, conformity and alignments on positions of opinion leaders in controversies still provide the best insights into the relationship between norms, structure and behavior.     

千城一面——造城时代下的物竞天择

随着对城镇化质量的日益关注,媒体与学界对千城一面的批判愈演愈烈。然而,如果将城市看做是地球生态系统的一部分,遵循生物界优胜劣汰、适者生存的丛林法则,那么千城一面现象便是时代背景下环境选择的结果——特定的科技、经济、文化发展水平等客观属性,把在生存竞争中处于劣势的建筑形制与空间范式逐一淘汰,筛选出最符合时代需求与发展方向的特征传承下去。在理解千城一面的时代必然性的基础上,理性认识古典主义与现代主义、空间舒适性与独特性、空间使用者的主与客之间的辩证关系,才能走出"为批判而批判"的误区。     

城市多元生鲜市场空间格局的演变及其相互关联——以昆明主城区为例

生鲜市场关系到民生、城乡经济联系和就业等问题,孤立地研究某一类型的生鲜市场具有片面性,不利于理解整个城市的生鲜市场功能和全局管理。通过对昆明市主城区各种生鲜市场实地调查和问卷,运用ArcGIS空间叠加分析、核密度分析和统计分析等多种方法描述了该城市多元生鲜市场的空间格局的形成和演变,归纳不同生鲜市场的特征及其多元生鲜市场共存格局的原因,并对未来演变趋势进行分析,提出此消彼长的互动关联性对各主体所隐含的机遇和挑战,由此说明从地域视角开展的研究,能综合把握全局特征,以及各类型之间的彼此关联性,可弥补以往单一类型研究的不足,并对政府的相关决策进行讨论。

基于个性化需求的产品竞争供应链结构选择

基于"制销分离"与"定制一体"两种结构选择,构建个性化产品供应链处于非竞争与竞争环境下的博弈模型,在引入一个实际案例的基础上,运用算例仿真比较分析两种运营模式下的供应链运作策略和盈利差异。结果显示：与制销分离结构相比,个性化产品供应链选择定制一体结构,有利于匹配产品个性化制造、提升产品个性化水平和市场需求、增加供应链的期望收益;个性化产品供应链选择制销分离结构时,适度的批发价格激励能够提升产品个性化水平、更好满足消费者个性化需求、改善供应链的运营绩效,分销商适度让利加大批发价格激励力度可显著促进产品个性化制造互动、提升产品个性化水平;竞争将消减个性化产品供应链的运营绩效,但选择定制一体结构可显著提升竞争力。     

A multicriteria sorting approach based on data envelopment analysis for R&D project selection problem

In this paper, multiple criteria sorting methods based on data envelopment analysis (DEA) are developed to evaluate research and development (R&D) projects. The weight intervals of the criteria are obtained from Interval Analytic Hierarchy Process and employed as the assurance region constraints of models. Based on data envelopment analysis, two threshold estimation models, and five assignment models are developed for sorting. In addition to sorting, these models also provide ranking of the projects. The developed approach and the well-known sorting method UTADIS are applied to a real case study to analyze the R&D projects proposed to a grant program executed by a government funding agency in 2009. A five level R&D project selection criteria hierarchy and an assisting point allocation guide are defined to measure and quantify the performance of the projects. In the case study, the developed methods are observed to be more stable than UTADIS.
