兰姆及其所著《麦克马洪线》

本文对英国学者兰姆的生平和学术生涯做了一个较为详细的梳理,在此基础上介绍了其著作《麦克马洪线:1904-1914年印度、中国和西藏关系史研究》,认为这是一部研究中印关系,特别是中印边界问题的经典著作。深入的分析、缜密的考证,以及比较客观的叙述,展现出作者严谨的治学态度。与西方大多数学者不同的是,兰姆在书中用事实有力地驳斥了印度政府妄图继承英帝国遗产的观点,提出了许多值得参考的看法。同时,也指出了该书存在的不足之处。     

我国地方食品安全监管体系研究——以江苏省为例

食品安全一直是每个国民心中的"中国梦"。随着政府机构改革对食品安全问题的日益重视,新的监管体系正在形成。而地方政府作为国家食品安全监管的具体执行者,其所处的地位、所承担的责任、所拥有的权限决定了它是整个监管工作的关键。本文通过对江苏省食品安全监管体系的研究,尝试提出解决食品安全监管问题的建议。     

行业系统性风险的动态特征及其影响因素

现代经济主体间网络关联性越来越强,风险很容易在不同行业间扩散,因此有效识别并分析系统性风险是防范金融危机的关键步骤。基于条件风险价值(CoVaR)和边际期望损失(MES)两个指标,对巨潮行业指数系统性风险的静态和动态特征进行了研究。结果发现,各行业间系统性风险的相关性较强,动态特征显示2009年年初和2016年3月为系统性风险的两个峰值;从分行业来看,材料行业的系统性风险最高,而消费和医药行业的系统性风险最低。采用动态面板模型分析影响行业系统性风险的市场面因素发现,短期涨幅较高、长期涨幅较低及流动性较充分的行业,其系统性风险往往更低。因此,应加强对系统性风险较高行业的监管力度,建立好金融防火墙,防止外部金融风险的过度传染;同时应加强对各行业的实时监控,尤其是关注短期暴涨暴跌及流动性充分与否的监控。

Measuring and Achieving Equity in Multiperiod Emergency Material Allocation

Emergency material allocation is an important part of postdisaster emergency logistics that is significant for improving rescue effectiveness and reducing disaster losses. However, the traditional single‐period allocation model often causes local surpluses or shortages and high cost, and prevents the system from achieving an equitable or optimal multiperiod allocation. To achieve equitable allocation of emergency materials in the case of serious shortages relative to the demand by victims, this article introduces a multiperiod model for allocation of emergency materials to multiple affected locations (using an exponential utility function to reflect the disutility loss due to material shortfalls), and illustrates the relationship between equity of allocations and the cost of emergency response. Finally, numerical examples are presented to demonstrate both the feasibility and the usefulness of the proposed model for achieving multiperiod equitable allocation of emergency material among multiple disaster locations. The results indicate that the introduction of a nonlinear utility function to reflect the disutility of large shortfalls can make the material allocation fairer, and minimize large losses due to shortfalls. We found that achieving equity has a significant but not unreasonable impact on emergency costs. We also illustrate that using differing utility functions for different types of materials adds an important dimension of flexibility.     

循环的“真”概念与真理修正理论探析

美国哲学家古普塔提出了"真理修正理论",试图修复克里普克建立在强克林三值逻辑基础上的不动点理论的缺点,进一步说明"真"概念在自然语言中的用法,从而成为解决语义悖论之语境迟钝进路的最重要代表。该理论的关键是承认"真"是一个循环概念,并依据循环定义提出修正规则,用修正规则来阐明"真"概念的实际使用。在分析真理修正理论所受到的批评与辩护的基础上,运用RZH解悖标准辨析可以表明,该理论进一步研究的焦点在于其作为一种解悖方案的"非特设性"哲学说明,特别是"真"作为一个循环概念这一前提的可接受性。

Premium of Endowment Insurance for Civil Servants will be Paid by Employers and Individuals

There is finally precise information about the reform in endowment insurance to abolish the"double-track system".On December 23,2014,Mr.Ma Kai,Vice Premier of the State Council,delivered a work report on behalf of the State Council at the 12th Session of the Standing Committee of the Twelfth National People’s Congress about the progress made in comprehensively advancing the establishment of urban     

A Sociology of the Periphery Versus a Peripheral Sociology: Rural Sociology and the Dimension of Space1

Abstract Rural sociology is intrinsically concerned with the spatial dimensions of social life. However, this underlying research tradition, particularly the use of space as a research strategy, has been insufficiently addressed and its contributions to general sociology are little recognized. I outline how concern with space, uneven development, and the social relationships of peripheral settings have provided substantive boundary and conceptual meaning to rural sociology, propelled its evolution, and left it with a legacy of strengths, weaknesses, and challenges. A willingness to tackle the dimension of space and the thorny problems it raises often sets rural sociologists apart from other sociologists. This research tradition contrasted with general sociology's concern with developing generalization, aspatial covering laws, and proto-typical relationships of modern or Fordist development settings. Conceptual openings have left sociologists questioning their past agenda. Coupled with the “creative marginality” inherent in the questions and contexts addressed by rural sociologists, this makes the subfield central to contemporary sociology.
