Evaluating the causal economic impacts of transport investments: evidence from the Madrid–Barcelona high speed rail corridor

This paper evaluates economic impacts arising from the introduction of high-speed rail (HSR) between Madrid and Barcelona. Using difference-in-differences estimation we estimate an average treatment effect for provinces with stops on the HSR line of 2.4% for economic output, 3.3% for numbers of firms, and 1.1% for labour productivity. We complement our DID results with a synthetic control analysis for Lleida and Tarragona, two provinces that we argue were assigned HSR stations largely due to their incidental location. We find that both the number of firms and labour productivity are substantially higher in these provinces than in their synthetic counterparts.     

应用型高校与企业共建产业学院的优势与困惑

产业学院是应用型高校为服务地方社会经济的发展而与企业深度合作形成的新型办学机构，由高校和企业共同投资，实行理事会领导、院长负责的管理体制，校企协同育人，重视实践教学，组织特征鲜明，办学优势突出。但是，产业学院在发展过程中面临诸多不足：独立法人地位尚未确立，进一步发展缺乏法律保障和依据；现代治理方式和结构尚未建立，具体工作受高校干扰较多，行政化色彩浓厚；运行成本大，缺乏市场化运行机制。为了促进产业学院发展，国家应确立其独立的法律地位，营造发展的政策环境和建立现代化的治理方式与结构；产业学院应建立市场化运行机制，激发面对市场的应变能力，最大限度地发挥自身优势，化解发展过程中的短板。     

比较法视野下我国搜查措施之理论反思

我国有证搜查还处于内部控制、自我约束和事后监督的阶段。被搜查者的合法权利不得不严重依赖于侦查人员搜查的文明程度。而无证搜查立法的拘谨与侦查实践的现实需要之间存在显著的差异。我国搜查措施所存在的问题,显示出搜查措施对侦查机关的规范和约束力度还处于较低的水平,对被搜查者权利的保障仍有所不足。我国不仅需要完善有证搜查制度,而且更需要建立和规范以同意搜查为核心的无证搜查制度,以追随刑事诉讼现代化之步伐,实现法治中国之梦想。     

产品服务供应链的“双重收益共享”合作机制

产品与服务融合缓解了"供需错位"矛盾，使得产品服务供应链探索成为"供给侧结构性改革"下供需结构性匹配的重要路径。本文刻画产品服务视角下供应链组织结构的本质特征，构建产品服务供应链合作模型，探讨合作机制下"帕累托改进"区间存在性，揭示合作机制对产品服务供应链效率的作用机理。核心研究发现：供应链多元化组织结构加剧收益分配冲突，并导致服务规模与供应链效率"倒挂"现象，而合作机制下"双重收益共享"合作模型能提升产品服务供应链效率。     

劳动合同法视域下福建自贸区弹性用工研究

弹性用工是一种灵活的用工方式，是实现人力资源最优配置的有效途径。我国对弹性用工不合理的制度设计，限制了弹性用工效用的发挥，这些制度包括：劳动合同期限制度、劳务派遣制度、特殊工时制度、非全日制用工制度。     

铝合金抽油杆柱深抽的初步研究

机抽井深抽是恢复油井产量行之有效的措施，为解决钢质杆深抽时驴头负荷、曲柄扭矩和杆柱应力过大的问题，我国西部某油田提出了使用铝合金抽油杆的设想。本主根据抽油杆柱设计理论导出了深抽杆柱各级下入深度的公式；对不同工艺参数配合下的计算结果进行了对比分析，对铝合金抽油杆柱用于深抽的可行性进行了初步研究。     

抗战时期陕甘宁边区学前教育建设的经验与启示

抗战时期，陕甘宁边区在中国共产党的领导下进行了独具特色的学前教育建设活动，形成了独特的建设经验，主要包括提供保障措施、建立精简高效的组织架构、注重保教队伍的建设、关爱幼儿的身体健康、开展科学的教育教学工作。重现边区学前教育活动，探寻其成功经验，继承与发扬红色教育精神，对新时期幼儿的培养与培育有积极的现实指导意义。     

Transition probabilities and ARL performance of Six Sigma zone control charts

In this article, Six Sigma zone control charts (SSZCCs) are proposed for world class organizations. The transition probabilities are obtained using the Markov chain approach. The Average Run Length (ARL) values are then presented. The ARL performance of the proposed SSZCCs and the standard Six Sigma control chart (SSCC) without zones or run rules is studied. The ARL performance of these charts is then compared with those of the other standard zone control charts (ZCCs), the modified ZCC and the traditional Shewhart control chart (SCC) with common run rules. As expected, it is shown that the proposed SSZCC outperforms the standard SSCC without zones or run rules for process shifts of any magnitude. When compared to the other standard ZCCs and the Shewhart chart with common run rules, it is observed that the proposed SSZCCs have much higher false alarm rates for smaller shifts and hence they prevent unwanted process disturbances. The application of the proposed SSZCC is illustrated using a real time example.     

Is there a global super-bourgeoisie?

In recent decades, accelerating processes of globalization and an increase in economic inequality in most of the world's countries have raised the question of the emergence of a new bourgeoisie integrated at the global level, sometimes described as a global super-bourgeoisie. This group would be distinguished by its unequaled level of wealth and global interconnectedness, its transnational ubiquity and concentration in the planet's major global cities, its specific culture, consumption habits, sites of sociability and shared references, and even by class consciousness and capacity to act collectively. This article successively discusses how the social sciences have examined these various dimensions of the question and begun to provide systematic empirical answers.
