Who Should Pay for Interdependent Risk? Policy Implications for Security Interdependence Among Airports

We study interdependent risks in security, and shed light on the economic and policy implications of increasing security interdependence in presence of reactive attackers. We investigate the impact of potential public policy arrangements on the security of a group of interdependent organizations, namely, airports. Focusing on security expenditures and costs to society, as assessed by a social planner, to individual airports and to attackers, we first develop a game-theoretic framework, and derive explicit Nash equilibrium and socially optimal solutions in the airports network. We then conduct numerical experiments mirroring real-world cyber scenarios, to assess how a change in interdependence impact the airports' security expenditures, the overall expected costs to society, and the fairness of security financing. Our study provides insights on the economic and policy implications for the United States, Europe, and Asia.     

多边贸易体制下中国发展中国家地位问题研究——基于历史、现实与规范的多维考察

当前,发展中国家地位问题受到国际社会的高度关注,已成为世界贸易组织改革中的主要讨论议题。然而,现行世界贸易组织多边规则体系中并没有关于“发展中国家地位”的清晰界定,“自我认定”的方式正遭受一些国家的挑战。发展中国家地位和特殊与差别待遇条款密切相关,世界贸易组织规则体系中涵盖的155项特殊与差别待遇条款为发展中国家的国内政策提供了一定的灵活性,尽管多数为“最佳努力条款”。中国的发展中国家地位兼具身份和契约的双重属性,部分发达国家迫使中国放弃发展中国家地位,本质上旨在继续维持其在国际经济秩序中的主导地位。虽然中国的发展正处于“强起来”的第三阶段,但仍须坚持发展中国家地位不动摇。放弃发展中国家地位并不等于将获得发达国家的自动接纳,相反,还会影响到在其他国际组织和国际事务中的角色扮演,中国的发展离不开广大发展中国家的支持。当然,坚持发展中国家地位并不等于需要和其他发展中成员享受完全一致的差别待遇,在后续谈判中,中国可以保持一定的灵活性。在国际治理中,中国也将继续为国际社会的发展提供解决方案,树立负责任大国形象。     

Risk factors for child maltreatment in South Korea: An investigation of a nationally representative sample

This study investigated the risk factors associated with the occurrence of child physical and psychological abuse in South Korea based on the ecological theory of child maltreatment. A subsample of 3‐ to 18‐year‐old children from “A Study on the Current State of Child Abuse and Neglect,” a nationally representative study on child abuse and neglect, was utilized for secondary data analysis. The sample was divided into two age groups (third graders in elementary school and below and fourth graders and above). We utilized hierarchical logistic regression for each age group separately to analyze the data. The variables at each level of the system (i.e., ontogenic development, microsystem, and exosystem) were entered into the model in sequential order. The results showed the common risk factors for both age groups are the caregiver's experience of abuse in childhood, the child's problem behavior, exposure to domestic violence, community size, and informal social control. The child's age was also significant in both groups but in the opposite direction. Social support was a significant predictor for the younger age group only, while the caregiver's level of education was significant for the older age group only. Implications for future research and practice are discussed based on the study results.     

进化论思潮与唯物史观的传播——近代中国两大思想关系刍议

进化论思想与唯物史观同为近代中国影响广泛的思想。二者的传入时间接近，并且都经历了中国化的过程。随着进化论思想在现代遭到了越来越多的批判和质疑，唯物史观早期传播和发展的历程也经历了重新的审视。文章从近代思想史发展的事实出发，重新厘清两种思想的关系，并具体论证马克思的唯物史观能否从广义上归结为一种进化论的思想，以及进化论思想在中国是否经历了一个向唯物史观转变的历程。     

君主专制与政治抵制:早期现代英国法律语境中的《复仇者悲剧》

英国自都铎王朝后期至斯图亚特早期，立宪君主论或混合君主论者抵制君权神授论，坚持家庭是一个自治的、涉及臣民私人权益的小政府，受到自然法、古代宪法或神圣法的保护。《复仇者悲剧》中公爵王室言行映射詹姆士一世在《皇家礼物》中所宣扬的君权神授论，温迪斯兄弟俩及追随者的复仇隐含当时的政治抵制学说，公爵王室与温迪斯兄弟俩的对立象征君权神授论与普通法理论的对峙。温迪斯兄弟俩却以威胁新君为由被处死，司法斗争简约为复仇冲动，维权英雄陡变为暴徒，暴君化身为明君，这暴露出君权神授论的悖论性和剧作家含混的复仇伦理。     

先秦的“法治”思想和实践考量

先秦法家在与儒家“礼治”的争论中提出“法治”思想,并与战国时期富国强兵的国家策略结合,变法图存的“法治”实践此起彼伏。其中最为成功的是秦国的商鞅变法,秦国由此迅速崛起并最终吞并六国,建立起统一的封建国家。秦帝国的建立是“法治”思想和实践的里程碑,大秦将集权专制和“法治”相互糅合,将法家重刑思想发展到极端,走向了崇尚暴力和滥刑滥杀的野蛮恐怖境地,导致天下怨叛,秦王朝二世而亡,君权至上最终将法治引向了集权专制的死胡同。     

Theorising the power of citizenship as claims-making

I advance a conceptual approach to citizenship as membership through claims-making. In this approach, citizenship is a relational process of making membership claims on polities, people and institutions, claims recognized or rejected within particular normative understandings of citizenship. Such a conceptual shift moves scholarship beyond typologizing—enumerating how citizenship is (or is not) about status, rights, participation and identity—to identifying the mechanisms through which claims on citizenship have power. This framework requires a relational approach and attention to dynamics of recognition within contexts of structured agency. Immigrants and their children can make claims to modify the normative content of citizenship, affect recognition evaluations and change the allocation of status and rights. But they are also constrained by legal structures, a society's institutional practices, and prevailing public perceptions. Citizenship as claims-making may require a reassessment of boundary approaches and a turn to metaphors of positionality, as well as more serious commitment to mixed-methods research. The stakes of understanding citizenship's power, as practice and status, are especially high right now. Yet based on existing scholarship, it is not entirely clear how much citizenship matters, in what ways, for whom, or why. This is the challenge for future scholarship.     

Restricted minimax estimation in semiparametric linear models

Abstract

In this article we develop the minimax estimation approach of general linear models to the semiparametric linear models when the parameters are simultaneously constrained by an ellipsoid and linear restrictions. Combining sample information and prior constraints the minimax estimator is obtained and compared with partially least square estimator by theoretical and simulation methods.

Security Investment in Contagious Networks

Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game‐theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost‐effective decisions than selfish nonrational or semirational players.
