Aging and ordering properties of multivariate lifetimes with Archimedean dependence structures

This paper further studies monotone aging properties of the multivariate random lifetime. We revise the sufficient condition for the negative monotone aging property in terms of the multivariate usual stochastic order in Theorem 3.3 of Rezapour et al. (2013) Rezapour, M., Alamatsaz, M.H., Pellerey, F. (2013). Multivariate aging with Archimedean dependence structures in high dimensions. Commun. Stat. - Theory Methods 42:2056–2070.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] and derive the condition sufficient to the multivariate monotone aging properties in terms of the upper orthant order. Also we study the upper orthant order of multivariate residual lifetimes and inactivity times from populations sharing a common Archimedean survival copula and Archimedean survival copula, respectively. Two simple applications in multivariate stress-strength and frailty models are presented as well.     

A note on mixingale limit theorems and stable convergence in law

A gap in the proof of a non stationary mixingale invariance principle is identified and fixed by introducing a skipped subsampling of a partial sum process and letting the skipped interval vanish asymptotically at an appropriate rate as the sample size increases. The corrected proof produces a mixingale limit theorem in the form of a mixing convergence in law, occurring jointly with the stable convergence in law for the same σ-field relative to which they are stable and mixing. The applicability of established results to a high-frequency estimation of the quadratic variation of financial price process is discussed.     

Enforcing cooperation in public goods games: Is one punisher enough?

We experimentally investigate a finitely repeated public goods game setting where, in each round, access to sanctioning power is exclusively awarded to one single player per group. We show that our central ‘Top Contributors as Punishers’ institution – a mechanism by which a player needs to be the highest contributor in her group in order to earn the right to sanction others – is extremely effective in raising cooperation and welfare due to turnover in the top contributor role and to top contributors’ willingness to substantially sanction others. Our findings yield implications for the design of mechanisms intended to foster cooperation in social dilemma environments.     

Virtual Worlds and Social Work Education

ABSTRACT

The introduction of computerised virtual worlds in the early twenty-first century was considered to be an innovation that would be widely used in higher education. There are a number of examples of virtual worlds used for higher education in medicine, nursing, and allied health, including examples in social work. The aim of this article is to explore the potential value of virtual-world technology to enhance the student learning experience for social work education in interpersonal communication skills in a virtual health centre. Findings of a study of Australian undergraduate social work students who engaged in a role play in a virtual health centre for skill development in interpersonal communication are presented. The study findings highlight issues for social work educators to consider when deciding whether or not to use virtual-world technology in social work education, and when designing further research on similar innovations.     

Demands and Devotion: Cultural Meanings of Work and Overload Among Women Researchers and Professionals in Science and Technology Industries

How do cultural meanings influence how people experience work‐life demands? Much research, especially quantitative research, on the effects of structural work and family conditions does not account for employees’ cultural beliefs about the meaning of work in their lives. This article uses unique survey data to investigate the effects of employee embrace of elements of the “work devotion schema”—a cultural model that valorizes intense career commitment and organizational dedication—on their sense of “overload,” an experience that includes feeling exhausted and overloaded by all one's roles, net of actual hours on the paid job and family responsibilities. We argue that by cognitively, morally, and emotionally framing work as a valued end, the work devotion schema reduces feelings of overload. Using a case of senior women researchers and professional service providers in science and technology industries, we find that those who embrace work devotion feel less overloaded than those who reject it, net of work and family conditions. However, this effect is curtailed for mothers of young and school‐aged children. We end by discussing implications for flexibility stigma and gender inequality.     

Patriarchal capitalism with Chinese characteristics: gendered discourse of ‘Double Eleven’ shopping festival

In this article we consider the Double Eleven shopping festival as a major discursive site where the hegemony of what we call patriarchal capitalism with Chinese characteristics is articulated. The state, the market, the corporations and the media, both mainstream and social media, all played an important role in building up a national spending spree that is deeply embedded in the current class and gender structure of China. The phenomenon of Double Eleven emerged at a time when state capitalism has been overwriting socialist institutions, while patriarchal ideology being further intensified through consumerism. As a consequence, the intersectionality of class and gender becomes increasingly manifest in the Chinese society. We start with a brief overview of the trajectory of gender politics in China since 1949, with specific focus on how the socialist project of seeking gender equality was gradually replaced by the quest for ‘womanhood’ and ‘femininity’. We then discuss, using both secondary sources and our own analysis of news coverage of Double Eleven, why maintaining a high level of consumer demand is of crucial importance for the Chinese state and what the state’s role has been in configuring the hegemonic gender order. A brief section on ideology and discourse lays out the conceptual framework of our analysis. It is at the intersection of a dissipating socialist ethos, emerging economic stagnation and ascending consumerism that the sexist discourse in relation to Double Eleven proliferates, and this is the analytical focus of our empirical section. We elaborate on the theoretical implications of the empirical analysis before concluding.     

Developing a model of disability that focuses on the actions of disabled people

Disabled people, writers on disability and disability activists stress the importance of disabled people being included in all aspects of society. I argue that a major omission from this inclusiveness is that no current model of disability focuses on the impact of the actions of disabled people on disability. Disabled people are not passive bystanders, powerless to reduce the restrictions of disability. On the contrary, we are central to actively limiting its constraints. I develop a model of disability, called ‘active’, which focuses on the effects on disability of the individual and collective actions of disabled people. I describe published findings which indicate that engaging in self-help, using support groups and deploying assistive technology can all reduce the limitations of disability. Recent increases in the number of disability support groups and developments in assistive technology have substantially augmented the potential for disabled people to combat the effects of disability.     

Violence against women in Spain and Cuba: The same reality,two different visions / Violencia hacia la mujer en España y Cuba: una misma realidad,dos visiones diferentes

This study aims to analyse the acceptance of gender violence in Spanish and Cuban populations. We analysed the influence of sexist beliefs and other ideologies that justify unequal gender relationships. A total of 230 men and women from Spain and 200 from Cuba participated by answering a questionnaire. The results showed the effect of participants’ gender and nationality as well as ideological variables (sexism, beliefs in a just world and codes of honour) that legitimise the status quo of gender violence. The male participants and the Cuban participants accepted violence against women more than the female participants and the Spanish participants. What is more, the results showed a pattern in the influence of the ideological variables that differed depending on the participants’ nationality. In Spain, the relationship between participants’ benevolent sexism and the justification of violence was mediated by codes of honour. In Cuba, the relationship between hostile sexism and acceptance of violence against women was mediated by beliefs in a just world.     

在世俗之上:“信仰中国”的认知与实践价值

李向平认为,从辛亥革命开始的现代中国"革命"运动对当代中国的"信仰"变迁及其重建产生了重要而深远的影响,源自于民国初年以"三民主义"为核心的"主义信仰"及其建构渐次成为"主义建构信仰"乃至"主义代替宗教"的政治思潮,深刻制约着现代中国"信仰"的建构与演变趋势。傅有德认为,与西方的信教主体不同,中国的宗教性信仰主体存在着较为普遍的"一人多信"现象,这既与宗教信仰间的兼容甚至合流有关,也与信仰而不必委身的理念有关,还与缺乏终极的精神关怀有关,更与中国人思维方式中"求同存异"的特点有关。任剑涛认为,中国迈上小康之路的这一变化,将四维中国的形象完整地刻画出来:"经济中国"构成中国的基础性物化维度,"政治中国"构成中国的国家—法律物化维度,"文化中国"构成中国的物质生活与精神生活的交叠维度,"信仰中国"构成中国的深刻价值支持维度;四个维度相互支撑,构成完整的、现代的"中国"。     

历史书写与记忆塑造(下)——古腾堡在近代中国

三清末民初编译、书写的西洋历史书籍及有关文类,虽然一般都称道古腾堡印刷术的贡献,将古腾堡印刷术与中国印刷术进行对比,但并没有将古腾堡印刷术导源于中国,尽管个别人曾将火药、罗盘这两大发明归于中国西传。然而,这样的历史书写模式并没有一以贯之。特别是在20世纪
