印度农业贸易自由化改革 ———基于粮食安全的视角分析

本文回顾了印度独立后农业发展所经历的四个阶段，并对这期间农业政策取得的成就和存在的主要问题进行了总结。然后重点探讨了印度贸易自由化改革的经验及其对农业增长、贫困削减和粮食安全的影响。研究发现，农业贸易自由化改革促进了农业的发展，并使农业内部的生产结构向增加高附加值产品生产的方向转变。贫困人口和贫困发生率在不断下降。在粮食安全方面，人们的粮食物质上的可获性已经得到满足，但粮食经济上的可获性还没有得到完全满足。今后可以通过大力发展农村非农部门来增加就业和削减贫困，并最终实现粮食安全的目标。     

农业贸易自由化、贫困和粮食安全：印度的经验

回顾了印度独立后农业发展所经历的四个阶段，并对这期间农业政策取得的成就和存在的主要问题进行了总结。重点探讨了印度贸易自由化改革的经验及其对农业增长、贫困削减和粮食安全的影响。研究发现，农业贸易自由化改革促进了农业的发展，并使农业内部的生产结构向增加高附加值产品生产的方向转变；贫困人口和贫困发生率在不断下降；在粮食安全方面，人们的粮食物质上的可获性已经得到满足，粮食经济上的可获性也随着PDS的实施和居民收入水平的不断提高而得到了一定的改善。     

中国城市化发展对粮食生产影响分析

1990年之后,我国粮食生产变动较大,同时我国城市化的两个主要方面——人口城市化和土地利用城市化继续迅速发展,分别表现为:粮食总产量波动很大,人均粮食产量呈减少趋势;人口城市化保持快速推进,导致农业劳动力数量减少、素质弱化;土地利用的城市化发展速度更快,造成耕地面积减少、质量不断降低。数据分析显示,我国目前粮食生产仍主要依靠劳动力和耕地两大基本要素的投入,因此城市化的上述发展特征,将对中国粮食生产造成不利影响。     

THE PARTICIPATION DIVIDE: Content creation and sharing in the digital age

This paper looks at the prevalence of creative activity and sharing in an age when the barriers to disseminating material have been considerably lowered compared with earlier times. The authors use unique data to explore the extent to which young adults create video, music, writing and artistic photography, as well as the prevalence of sharing such material online. Findings suggest that despite new opportunities to engage in such distribution of content, relatively few people are taking advantage of these recent developments. Moreover, neither creation nor sharing is randomly distributed among a diverse group of young adults. Consistent with existing literature, creative activity is related to a person's socioeconomic status as measured by parental schooling. The novel act of sharing online, however, is considerably different by gender with men much more likely to engage in it. However, once internet user skill is controlled for, men and women are equally likely to post their materials on the Web.     

民族自治地方农村养老问题与对策初探——以黔东南州锦屏县为例

民族自治地方农村养老工作与构建社会主义和谐社会、社会主义新农村建设、“三农”问题等紧密相关，养老工作能否解决好直接影响到农村的社会稳定、社会的和谐发展和“三农”问题的解决。民族自治地方农村经济相对落后、经济发展不平衡、人口分布不均衡、农村老年人口日益增多、农民工大量外出等现实，给传统养老方式带来了历史性的冲击。这要求建立具有时代特色和地方特色的养老方式。本文在进行充分的实地调查、分析黔东南苗族侗族自治州锦屏县农村现行的养老方式现状、养老方式存在问题的基础上，结合当地实际情况和借鉴其他地方的成功养老方式，提出具体可行的对策。     

论网络文学的文体学创新

从文学文体学角度对网络文学的文体学创新进行研究,认为网络文学的文体创新主要表现为三个方面:即体裁创新、语体创新和风格创新。三者共同构成了网络文学较之传统文学不同的文体特征。它们赋予网络文学以生机,同时也提出了一些值得进一步思考的问题。     

证券市场的开放与规则的发展--以B股规则为中心的检讨

人民币特种股(B股)市场作为我国证券市场开放的窗口和试验田,至今已存在10余年,相比它短暂的辉煌,如今的B股市场已经日益“边缘化”,除了进行投机,B股还能为中国证券市场开放做些什么?结合我国证券市场的特点,深入分析B股市场的发展及其规则变迁,认真总结其经验和教训,对我国在证券市场开放过程中建立健全相关法律制度很有借鉴意义。

Using Probabilistic Terrorism Risk Modeling for Regulatory Benefit-Cost Analysis: Application to the Western Hemisphere Travel Initiative in the Land Environment

This article presents a framework for using probabilistic terrorism risk modeling in regulatory analysis. We demonstrate the framework with an example application involving a regulation under consideration, the Western Hemisphere Travel Initiative for the Land Environment, (WHTI‐L). First, we estimate annualized loss from terrorist attacks with the Risk Management Solutions (RMS) Probabilistic Terrorism Model. We then estimate the critical risk reduction, which is the risk‐reducing effectiveness of WHTI‐L needed for its benefit, in terms of reduced terrorism loss in the United States, to exceed its cost. Our analysis indicates that the critical risk reduction depends strongly not only on uncertainties in the terrorism risk level, but also on uncertainty in the cost of regulation and how casualties are monetized. For a terrorism risk level based on the RMS standard risk estimate, the baseline regulatory cost estimate for WHTI‐L, and a range of casualty cost estimates based on the willingness‐to‐pay approach, our estimate for the expected annualized loss from terrorism ranges from $2.7 billion to $5.2 billion. For this range in annualized loss, the critical risk reduction for WHTI‐L ranges from 7% to 13%. Basing results on a lower risk level that results in halving the annualized terrorism loss would double the critical risk reduction (14–26%), and basing the results on a higher risk level that results in a doubling of the annualized terrorism loss would cut the critical risk reduction in half (3.5–6.6%). Ideally, decisions about terrorism security regulations and policies would be informed by true benefit‐cost analyses in which the estimated benefits are compared to costs. Such analyses for terrorism security efforts face substantial impediments stemming from the great uncertainty in the terrorist threat and the very low recurrence interval for large attacks. Several approaches can be used to estimate how a terrorism security program or regulation reduces the distribution of risks it is intended to manage. But, continued research to develop additional tools and data is necessary to support application of these approaches. These include refinement of models and simulations, engagement of subject matter experts, implementation of program evaluation, and estimating the costs of casualties from terrorism events.
