农村权力结构嬗变与农民权利实现的互动关联

农民权利的实现问题是当下农村问题解决的关键,对农村乃至中国的民主政治建设和政治发展有着重要影响。农民权利的实现困境根源在于权力结构与农民权利诉求未达成契合,权力运行与权利实现之间缺失了均衡性。因此必须合理调适农村现行权力结构,以对农民权利的认可和保障为旨归,在权力与权利的互动关联中,构筑农民权利实现的屏障。

重点产业政策对出口再分配的影响

基于2000-2013年海关数据与各省份五年规划数据,本文考察了重点产业政策对出口再分配的影响机制。研究发现,政府对特定行业的支持会引致产品维度不同类型企业间的出口再分配;产品市场获得支持会吸引潜在出口商参与出口、争夺市场份额,也会吸引在位出口商将部分业务转移到获得政策支持的行业、进行业务试探;同时,市场竞争的加剧也会加速淘汰竞争力较差的中小企业,促进产品维度新旧企业的更新换代。进一步,本文通过对比不同类型企业的出口动态,考察了重点产业政策对企业出口平均单价与产品质量的影响,发现政府对特定行业的支持会降低出口市场的准入门槛,导致更多的低价低质企业进入市场。可见,适度的政策支持有助于产品市场内企业的更新换代,激发市场活力;但政策的制定必须兼顾企业更新换代过程中的质量攀升机制,才能充分发挥其对出口再分配的优化作用,推动对外贸易的可持续发展。

在华外国人犯罪的刑事法律应对

伴随北京、上海等国际化大都市的出现、增多和整个国家国际化进程的加快,中国境内的外国人口激增,中国开始面临长期困扰西方发达国家的外国人犯罪问题。文章在分析北京地区近10年外国人犯罪的规律和趋势的基础上,着力思考如何解决城市、国家的国际化发展与外国人犯罪应对体系滞后的现实问题,如何构建与城市、国家的国际化程度相适应的外国人犯罪刑事政策,如何设置顺应国际人口流动的出入境犯罪罪名体系,如何在全球化趋势下扩张中国刑法的适用范围、强化属地管辖意识和增强国际刑事司法协作,从而尝试为应对中国境内国际化大都市的逐渐增多和整个国家国际化程度的日益提高而做好法律层面的准备提供学理支持。

State of the Art in Risk Analysis of Workforce Criticality Influencing Disaster Preparedness for Interdependent Systems

The objective of this article is to discuss a needed paradigm shift in disaster risk analysis to emphasize the role of the workforce in managing the recovery of interdependent infrastructure and economic systems. Much of the work that has been done on disaster risk analysis has focused primarily on preparedness and recovery strategies for disrupted infrastructure systems. The reliability of systems such as transportation, electric power, and telecommunications is crucial in sustaining business processes, supply chains, and regional livelihoods, as well as ensuring the availability of vital services in the aftermath of disasters. There has been a growing momentum in recognizing workforce criticality in the aftermath of disasters; nevertheless, significant gaps still remain in modeling, assessing, and managing workforce disruptions and their associated ripple effects to other interdependent systems. The workforce plays a pivotal role in ensuring that a disrupted region continues to function and subsequently recover from the adverse effects of disasters. With this in mind, this article presents a review of recent studies that have underscored the criticality of workforce sectors in formulating synergistic preparedness and recovery policies for interdependent infrastructure and regional economic systems.

An Integrated Risk Assessment Model of Township‐Scaled Land Subsidence Based on an Evidential Reasoning Algorithm and Fuzzy Set Theory

Land subsidence risk assessment (LSRA) is a multi‐attribute decision analysis (MADA) problem and is often characterized by both quantitative and qualitative attributes with various types of uncertainty. Therefore, the problem needs to be modeled and analyzed using methods that can handle uncertainty. In this article, we propose an integrated assessment model based on the evidential reasoning (ER) algorithm and fuzzy set theory. The assessment model is structured as a hierarchical framework that regards land subsidence risk as a composite of two key factors: hazard and vulnerability. These factors can be described by a set of basic indicators defined by assessment grades with attributes for transforming both numerical data and subjective judgments into a belief structure. The factor‐level attributes of hazard and vulnerability are combined using the ER algorithm, which is based on the information from a belief structure calculated by the Dempster‐Shafer (D‐S) theory, and a distributed fuzzy belief structure calculated by fuzzy set theory. The results from the combined algorithms yield distributed assessment grade matrices. The application of the model to the Xixi‐Chengnan area, China, illustrates its usefulness and validity for LSRA. The model utilizes a combination of all types of evidence, including all assessment information—quantitative or qualitative, complete or incomplete, and precise or imprecise—to provide assessment grades that define risk assessment on the basis of hazard and vulnerability. The results will enable risk managers to apply different risk prevention measures and mitigation planning based on the calculated risk states.
