Restricted tests for testing independence of time to failure and cause of failure in a competing-risks model

We consider the competing-risks problem without making any assumption concerning the independence of the risks. Maximum-likelihood estimates of the cause-specific hazard rates are obtained under the condition that their ratio is monotone. We also consider the likelihood-ratio test for testing the proportionality of two cause-specific hazard rates against the alternative that the ratio of these two hazard rates is monotonic. This testing problem is equivalent to testing independence against likelihood-ratio dependence of the time to failure and the cause of failure in the competing-risks setup. We allow for random censoring on the right. The asymptotic null distribution of the test statistic is obtained and is found to be of the chi-bar-square type. The problem is extended to the case of more than two risks. A numerical example is given to illustrate the procedure.     

National Differences in the Diffusion and Design of Technological Innovation: The Role of Inter-Organizational Networks

This paper reports results from a study of the design and diffusion of computer-aided production management (CAPM) technologies across four European countries (UK, France, The Netherlands and Sweden). The study combined surveys of members of professional operations management associations in each of these four countries and interviews with operations managers and technology suppliers (software suppliers and consultants). The findings revealed significant differences across countries in the design and diffusion of CAPM. For example, in the UK and France highly objectified 'best practice' technologies, supported by standardized software, had diffused more widely than in Sweden and The Netherlands, where solutions tended to be developed in-house and customized to the local context. This paper explains these findings in terms of differences in the structure and operation of these four professional association networks. These differences in inter-organizational networking encouraged different types of knowledge-sharing related to the design of CAPM in the four countries.     

Student-workers and tourist-workers as urban labour: temporalities and identities in the Australian cosmopolitan city

ABSTRACT

Ethnic and cultural difference have long been regularly encountered and produced in Australian cities. However, these processes have predominantly been understood through the lens of permanent ‘settler’ migration. Recent migration policies are seeing increasing numbers of transnational workers residing in Australia with various noncitizen statuses and uncertain temporal horizons. Among these are student-workers and tourist-workers, who, although constructed through transient mobilities of education and leisure travel, play increasingly important roles in Australian cities as migrant labour. Drawing on fieldwork with student-workers and tourist-workers in Melbourne and Sydney, this paper seeks to examine how the temporal and legal status of these mobile subjects is entangled in complex ways with particular sites of production, consumption and labour within the cosmopolitan urban environment. It looks in particular at how the identities of student-workers and tourist-workers are constructed through specific temporal and spatial boundaries within urban space as well as how they are implicated within hierarchies of labour and spaces of cosmopolitan consumption. This highlights some of the complex socio-spatial relationships between and citizen and noncitizen subjects both within and across ethnic boundaries in the cosmopolitan city.     

An agenda for future research regarding the mental health of young people with care experience

Young people who are currently or were previously in state care have consistently been found to have much higher rates of mental health and neurodevelopmental difficulties than the general youth population. While a number of high-quality reviews highlight what research has been undertaken in relation to the mental health of young people with care experience and the gaps in our knowledge and understanding, there is, until now, no consensus, so far as we aware, as to where our collective research efforts should be directed with this important group. Through a series of UK wide workshops, we undertook a consultative process to identify an agreed research agenda between those with lived experience of being in care (n = 15), practitioners, policy makers and researchers (n = 59), for future research regarding the mental health of young people with care experience, including those who are neurodiverse/have a neurodevelopmental difficulty. This consensus statement identified 21 foci within four broad categories: how we conceptualize mental health; under-studied populations; under-studied topics; and underused methodologies. We hope that those who commission, fund and undertake research will engage in this discussion about the future agenda for research regarding the mental health of young people with care experience.     

Improving OpenURL Menus: User Testing of Revisions to SFX® Menus

Twenty-one volunteers tested the usability of revisions to the Texas A&M University Libraries' SFX® OpenURL link resolver menus, including the addition of Ex Libris' new bX™ recommendation service and a plug-in which pulls additional information about the journal into the menu. The volunteers also evaluated the quality and desirability of the bX recommendations and discussed their preferences for help options and full-text format. Results of the usability testing are reported along with the resultant menu changes. This study will be of interest to librarians implementing or redesigning OpenURL menus as well as those interested in the user experience.     

This Harlem life: black families and everyday life in the 1920s and 1930s

This article uses Probation Department files to reconstruct the lives of five ordinary residents of Harlem. It highlights what that black metropolis offered those outside the political and cultural elite, who have dominated historical scholarship, showing how ordinary blacks negotiated the challenges of life in northern neighborhoods, and drew on institutions and organizations, to establish and sustain new lives. We offer the kind of individualized perspective on everyday life that other scholars have provided for high culture, but which does not exist for other realms of existence in Harlem, even in early twentieth century sociological studies of black life. Where scholars seeking to distinguish the neighborhood from a slum have pointed to the prevailing pride and self-confidence of its residents, this article directs attention to more immediate, concrete supports that sustained and enriched life in Harlem. Relationships with spouses, children, siblings and cousins sustained individuals faced with the social reality of living in overcrowded, deteriorating, disease infested housing, subject to the racism of white police, politicians and employers; so too did friendships made in nightclubs, speakeasies, dances and movie theatres, and membership of churches, fraternal organizations, social clubs, and sports clubs and teams.     

The experience of gender dysphoria for pre‐pubescent children and their families: a review of the literature

In recent years, the experience of gender dysphoria has gained public prominence through an explosion of sensationalized interest in the popular media. However, childhood gender dysphoria remains poorly understood and both parents and children often find themselves having to educate professionals around them. This not only creates a sense of disconnect between family and professionals, but also means that social workers can often be unaware of the myriad of competing perspectives that seek to explain gender variance. This review of the literature seeks to provide interested social workers with an overview of gender dysphoria, current research in the field and theoretical paradigms, with a view to promoting understanding and better practice with families in this little understood field.     

Memory's Pillar and the Experience of Sexual Trauma Commentary on Janice Haaken's Pillar of Salt

In Pillar of Salt, Janice Haaken questions the claims of the advocates of recovered memory by exploring memory through a psychoanalytic lens as a process of reconfiguring the past in the light of present needs and desires. Resisting reductive formulations, she examines contemporary stories of abuse and concludes that, whether factual or not, the recovered-memory syndrome that has so starkly emerged in the past 20 years is true to women's experience of oppression within an abusive patriarchal culture. Read within the framework of subjectivity and meaning, recovered memories provide women with dramatic self-representations that give narrative structure to the truths of their lives.     

Increasing Child Serving Professionals’ Awareness and Understanding of the Commercial Sexual Exploitation of Children

ABSTRACT

Child serving professionals need increased understanding of the identification and therapeutic needs of child victims of commercial sexual exploitation. This study evaluated the effectiveness of a training program aimed to increase awareness of commercial sexual exploitation of children (CSEC) among professionals likely to encounter victims in their work. Professionals’ (N = 227) knowledge level was examined prior to the training, immediately thereafter, and in a 6–12 month follow-up. Despite professional position or years of experience, participants had similar levels of CSEC knowledge before the training and all showed a significant improvement in their knowledge after the training. However, follow-up testing on a smaller subsample demonstrated that knowledge gains were not maintained. The analysis of the participants’ responses to how their behavior would change subsequent to the training revealed important themes including: (1) greater ability to identify/assess or recognize CSEC victims, (2) greater understanding and knowledge of CSEC, (3) increased ability to communicate, interact, and engage with CSEC victims, and (4) heightened desire to educate others and raise awareness about CSEC. Results also indicated that participants were very satisfied with the training and found it highly relevant to their work.     

One of the Boys?

This article argues that American media reports of the Jessica Lynch case illustrate some of the ways in which gender has been reordered, policed and disciplined within the United States (and North America more broadly) in the wake of 9/11 and in the context of war. The study of a key gendered representation of the war – and of the way gender interlocks with race, class, nationality and sexuality in these representations – tells us not only about how the war was sold to the American public, but also about the degree to which normative and disciplinary gender roles can be stretched, or not, within domestic society and the ways in which contemporary media portrayals of foreign adventures serve to reinforce these gender norms. Ultimately we argue that media portraits of Jessica Lynch demonstrate how little the simple inclusion of women in the military acts to disrupt sexist systems of power and meaning.
