Free trade,food-processing,and migration: An analysis of Mexican immigration in the U.S. Great Plains Region

This paper empirically identifies the factors driving Mexican immigration into the U.S. Great Plains region, focusing especially on the role of work in the Mexican and U.S. food-processing sectors, which in the context of NAFTA-induced foreign direct investments, opens up paths for migration along occupational lines into the U.S. from Mexico. Using a unique dataset on Mexican migration, the study addresses three related questions in a series of multivariate logistic regression analyses. First, is employment in the U.S. food-processing sector associated with Mexican migration into the Great Plains region? Second, does employment in the Mexican food-processing sector predict employment in the Great Plains food-processing sector? Finally, is the political–economic context linking Mexico and the U.S. related to the formation of occupational channels linking the food-processing sectors in Mexico and the U.S.? The findings demonstrate that the U.S. food-processing sector is a strong predictor of Mexican migration to the Great Plains region; Mexican migration is strongly channeled along occupational lines from Mexico to the U.S.; and the implementation of NAFTA, a period of intensive political–economic integration, strengthens the occupational channel between the food-processing sectors.     

上海自贸试验区建设对中国经济转型:机遇和挑战

上海自贸试验区实行加快政府职能转变、扩大投资领域开放、推进贸易发展方式改变、深化金融领域开放创新等一系列任务和要求,提出改革管理模式、创新税收制度、实施相关产业政策和建立风险防御体系等政策和措施。这不仅可为其他地区经济改革提供了范例,更有利于中国经济从当前粗放型发展模式向集约型转变。但在转变的过程中,中国经济将面临如何平稳过渡的挑战。     

Modelling free social spaces and the diffusion of social mobilization

Free social spaces have long been emphasized in the social movement literature. Under names such as safe spaces, social havens, and counterpublics, they have been characterized as protective shelters against prevailing hegemonic ideologies and as hubs for the diffusion of ideas and ideologies. However, the vast literature on these spaces has predominantly focused on internal dynamics and processes, thus neglecting how they relate to the diffusion of collective mobilization. Inspired by formal modeling in collective action research, we develop a network model to investigate how the structural properties of free social spaces impact the diffusion of collective mobilization. Our results show that the assumption of clustering is enough for structural effects to emerge, and that clustering furthermore interacts synergistically with political deviance. This indicates that it is not only internal dynamics that play a role in the relevance of free social spaces for collective action. Our approach also illustrates how formal modeling can deepen our understanding of diffusion processes in collective mobilizations through analysis of emergent structural effects.     

An Entropy‐Based Methodology for Valuation of Demand Uncertainty Reduction

We propose a distribution‐free entropy‐based methodology to calculate the expected value of an uncertainty reduction effort and present our results within the context of reducing demand uncertainty. In contrast to existing techniques, the methodology does not require a priori assumptions regarding the underlying demand distribution, does not require sampled observations to be the mechanism by which uncertainty is reduced, and provides an expectation of information value as opposed to an upper bound. In our methodology, a decision maker uses his existing knowledge combined with the maximum entropy principle to model both his present and potential future states of uncertainty as probability densities over all possible demand distributions. Modeling uncertainty in this way provides for a theoretically justified and intuitively satisfying method of valuing an uncertainty reduction effort without knowing the information to be revealed. We demonstrate the methodology's use in three different settings: (i) a newsvendor valuing knowledge of expected demand, (ii) a short life cycle product supply manager considering the adoption of a quick response strategy, and (iii) a revenue manager making a pricing decision with limited knowledge of the market potential for his product.     

医疗行为侵权诉讼举证责任分配之探讨

《证据规定》确定由医疗机构就医疗行为不存在医疗过错以及医疗行为与损害不存在因果关系承担举证责任,表面上看似有利于维护患者的利益,但是却欠缺其制度设计应有的合理性。《侵权责任法》虽然确立医疗行为侵权实行过错责任原则,但就举证责任如何分配并未明确予以规定。

逍遥游:艺术家的精神生活方式

"逍遥游"是中国艺术创生的关键词,更是艺术家生活状态的生动写照,它不是"形器"之游的物质生活方式,而是艺术家心灵"神游"的精神生活方式和生命放歌。在这样的精神"逍遥游"中,"深情"提供不竭动源,"童心"是其生命本体,"神游"呈现精神内核,"大美"是其创造成果。     

自由现金流代理成本假说还是过度自信假说?——中国上市公司投资——现金流敏感性的实证研究

企业投资现金流敏感性问题可以由现金流代理假说解释,也可以由管理者过度自信假说解释,本文以企业的成长性、现金流特征为划分指标对企业进行分组,并以此来区分与检验两种理论假说。研究结果显示,自由现金流代理问题较为严重的低成长—高现金流企业,将会发生企业过度投资。同样,过度自信问题较为严重的高成长—高现金流企业,也将发生企业过度投资。实证研究结果即支持了自由现金流代理假说,也支持了过度自信假说。     

自由发展观与科学发展观的比较研究

自由发展观打破了＂以物为中心＂的单纯追求经济增长的传统狭隘发展观旧范式,从自由的角度确立了一个＂以人为中心＂,崇尚自由与发展的新型发展观,认为自由既是发展的首要目的又是发展的重要手段;自由发展观与科学发展观存在诸多思想相通和理论关联之处,自由发展观为科学发展观的提出提供了重要的理论来源。通过二者的比较研究,一方面可以增强对自由发展观的深度理解,另一方面对学习和实践科学发展观具有重要的借鉴意义。
