A Grounded Theory of Sexual Minority Women and Transgender Individuals’ Social Justice Activism

Psychosocial benefits of activism include increased empowerment, social connectedness, and resilience. Yet sexual minority women (SMW) and transgender individuals with multiple oppressed statuses and identities are especially prone to oppression-based experiences, even within minority activist communities. This study sought to develop an empirical model to explain the diverse meanings of social justice activism situated in SMW and transgender individuals’ social identities, values, and experiences of oppression and privilege. Using a grounded theory design, 20 SMW and transgender individuals participated in initial, follow-up, and feedback interviews. The most frequent demographic identities were queer or bisexual, White, middle-class women with advanced degrees. The results indicated that social justice activism was intensely relational, replete with multiple benefits, yet rife with experiences of oppression from within and outside of activist communities. The empirically derived model shows the complexity of SMW and transgender individuals’ experiences, meanings, and benefits of social justice activism.     

Deliberate acquisition of competence in physiological breech birth: A grounded theory study

Problem

Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems.

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.     

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。     

信息技术与高中数学课程整合探究

信息技术与数学课程整合已成为必然趋势,各种教学辅助软件的出现使教师应接不暇。数学软件Maple凭借其简单的操作和强大的功能等优势被越来越多的数学教师作为辅助教学软件。本文用数学实验的方法介绍了Maple在高中数学教学中的几个应用实例,并对信息技术与课程整合与传统教学法之间的优缺点进行了比较。     

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.     

论数字货币的私法性质——以日本Bitcoin.Cafe数字货币交易所破产案为中心

数字货币，是一种具有财产性价值属性的电磁记录型数据。数字货币在其依存的区块链体系中所彰显的与不特定者之间的支付对价性、与法定货币之间的互换性、使用电子信息处理系统进行转移的在线转移性等特点，得以从数据说的角度，将其作为一种数据性财产权在现行法律框架内对其私法性质进行讨论。有鉴于我国民法总则已将数据纳入保护客体的范畴，数字货币作为数据之一种，理应成为一种新型法律客体，在得到法律理论支撑的基础上获得保护。
