凉山彝区防止返贫的困境与对策

十八大以来,在党和国家的高度重视下,凉山彝区脱贫攻坚成绩斐然。2020年,凉山彝区10县区域性整体贫困问题全面消除。为了巩固彝区脱贫成果,守住不发生规模性返贫底线,推进彝区乡村振兴,实现彝区农业稳产、农民稳收、农村稳定,本文主要从凉山彝区的社会发育程度低、自然环境恶劣、交通发展滞后、公共基础薄弱、市场发展缓慢、内生动力缺乏等详细地分析了制约凉山彝区持久脱贫的困境因素;并就防止凉山彝区规模性返贫的困境因素,首先从政策、产业和互助合作方面对已有的主要帮扶措施进行了优化与健全,其次,从构建与完善保障督查、政策联动、内生动力激发、贫困文化消解、禁毒防艾和监测评估等机制方面提出了防止凉山彝区规模性返贫的对策建议。     

论港口产业规制契约的重新设计

20世纪70年代以后,在世界范围内出现港口产业规制改革浪潮,竞争机制和私人部门被更多地引入。那么在港口产业规制的新框架下,有必要对规制契约进行重新设计,以满足港口规制实践的需要。对包括价格上限规制、投资规制等在内的港口产业规制契约的核心内容进行了说明,并探讨了契约重新设计中若干关键要素的确定。     

Parenting Style,Child Emotion Regulation and Behavioral Problems: The Moderating Role of Cultural Values in Australia and Indonesia

Abstract

Research has shown that the congruence of parenting styles with cultural values, rather than parenting styles alone, impacts child adjustment. This study examined if parents’ cultural values moderate the relationships between parenting styles and child outcomes across both an individualist culture (Australia) and a collectivist culture (Indonesia). Three hundred and eighty-seven parents of 2–10-year-old children from both countries reported their parenting styles, the importance of the collectivistic values (security, conformity, and tradition), and their child's emotion regulation and behavioral problems. In both countries, authoritative parenting was associated with higher child emotion regulation and lower levels of behavioral problems, and authoritarian parenting was associated with lower child emotion regulation and higher levels of behavioral problems. Although cultural values did not moderate the relationship between authoritarian parenting and child adjustment, in both countries greater importance placed on tradition attenuated the positive effect of authoritative parenting on child outcomes.     

公共视频监控图像信息利用与保护的基本法律问题与立法规制

在智能化和法治化的新时代,公共视频监控图像信息综合应用已成为社会治理社会化、法治化、智能化和专业化的重要方式。公共视频监控系统成为政府部门和社会组织保护公共安全以及公民人身、财产安全的技术项目。公共视频监控图像信息的技术手段和法律属性需要以立法形式加以规定。公共视频监控图像信息综合应用需要在权利保护的法律制度中进行,尤其是视频监控图像信息公开使用与信息安全、隐私权保护之间的法律制度设计。因此,公共视频监控图像信息的法律规制工作应对法律主体、基本原则、权利体系、法律监管、法律责任做出明确规定。     

试论社会治理背景下政府与市场关系的经济法规制

政府与市场的关系问题是经济法规制的基于问题,如何正确看待政府与市场在经济生态系统内各自的功能及作用,是经济法规制的核心问题。因为这样的认识直接导致了经济立法的体系构建与内容规则。经济法规制是国家实施经济治理与尊重市场调节的基本依据,也是施行经济法治与社会治理的根本前提。所以,从社会治理的背景下来讨论经济法规制的社会经济发展的制度条件及制度生成条件,有利于真正建立和完善经济法规制的体系和内容,从而使得经济法治生态化地融入社会治理的结构体系内,达到优化社会制度以促进经济发展的目的。     

关于证券监管理念的法理分析

金融是“现代经济的核心”,证券市场是现代金融的重心。对证券进行监管是防范证券市场风险乃至整个金融市场风险的重要措施。监管理念是证券监管成败的关键,是证券市场发展的基石。文章从法学的角度,对监管理念进行深入的探讨,包括为什么要监管、如何监管、监管的适度、监管的方式等问题;梳理基本理论,比较国际标准;并且,希望为实现证券监管体系的有效运作,减少证券市场的风险,促进我国证券市场的进一步发展提供一些建议和参考。

The Legal Regulation of Irrational Elements in the Operations of Boards of Directors

The operating processes of boards of directors are delicate and complex, so corporate legislation cannot simply equate board structure law with board governance law. It is therefore necessary to start from China’s actual conditions and grasp the operating processes of Chinese boards with a sober appreciation of the irrational elements in their operating mechanisms. Board governance has entered a new stage of institutionalization, and the law should shift from its emphasis on structure to give equal attention to structure and process in optimizing institutional structure. In the construction of board operating mechanisms, we should treat differently such “living laws” as customs, experiences and traditions, give full play to the functionality of boards’ strategic choices, and provide legal regulation of irrational elements, so as to distinguish between different roles, develop consensus, select strong points and improve efficiency. We should build control over board operational procedures, improve the system of functional allocation, correct assessment mechanisms, develop a mechanism for judicial scrutiny of the affective relationships in society and curb such behavioral tendencies as relational identity, structural bias and group polarization, with a view to controlling such “living laws” within the framework of the basic values and principles of board governance.     

Minimal Risk in Pediatric Research: A Philosophical Review and Reconsideration

Despite more than thirty years of debate, disagreement persists among research ethicists about the most appropriate way to interpret the U.S. regulations on pediatric research, specifically the categories of “minimal risk” and a “minor increase over minimal risk.” Focusing primarily on the definition of “minimal risk,” we argue in this article that the continued debate about the pediatric risk categories is at least partly because their conceptual status is seldom considered directly. Once this is done, it becomes clear that the most popular strategy for interpreting “minimal risk”—defining it as a specific set of risks—is indefensible and, from a pragmatic perspective, unlikely to resolve disagreement. Primarily this is because judgments about minimal risk are both normative and heavily intuitive in nature and thus cannot easily be captured by reductions to a given set of risks. We suggest instead that a more defensible approach to evaluating risk should incorporate room for reflection and deliberation. This dispositional, deliberative framework can nonetheless accommodate a number of intellectual resources for reducing reliance on sheer intuition and improving the quality of risk evaluations.
