Methods for testing subblock patterns

A number of statistical tests have been recommended over the last twenty years for assessing the randomness of long binary strings used in cryptographic algorithms. Several of these tests include methods of examining subblock patterns. These tests are the uniformity test, the universal test and the repetition test. The effectiveness of these tests are compared based on the subblock length, the limitations on data requirements, and on their power in detecting deviations from randomness. Due to the complexity of the test statistics, the power functions are estimated by simulation methods. The results show that for small subblocks the uniformity test is more powerful than the universal test, and that there is some doubt about the parameters of the hypothesised distribution for the universal test statistic. For larger subblocks the results show that the repetition test is the most effective test, since it requires far less data than either of the other two tests and is an efficient test in detecting deviations from randomness in binary strings.     

Consensual Victim–Perpetrator Intercourse after Nonconsensual Sex: The Impact of Prior Relationship

Some female victims of nonconsensual sex subsequently have consensual sexual intercourse with the perpetrator and are more likely to do so if intercourse occurred during the nonconsensual sex than if it did not. Some evolutionary psychologists have postulated that there is something significant about nonconsensual intercourse that causes women to subsequently have a sexual relationship with the perpetrator (e.g., risk of pregnancy). In this study, we investigated a parsimonious explanation that has previously been overlooked: Intercourse is more likely during nonconsensual sex when the victim and perpetrator have previously had a sexual relationship; thus, subsequent consensual intercourse may simply be a continuation of that prior relationship. A sample of 945 women completed an Internet-based survey, of whom 41% had experienced nonconsensual sex since age 14. As expected, victims who had intercourse with perpetrators prior to the nonconsensual sex event were significantly more likely than other victims to experience nonconsensual intercourse and to engage in subsequent consensual intercourse with the perpetrator. When considering only the small subsample of victims who never had a prior romantic or sexual relationship with the perpetrator, the odds of subsequent consensual intercourse were still significantly greater following nonconsensual sex with intercourse versus without intercourse.     

A journey of embedding mental health lived experience in social work education

Abstract

The value of learning from mental health lived experience is widely acknowledged, however, the nature of lived experience involvement in Australian social work education seldom extends beyond guest lecturing. Further, few opportunities exist that build the capacity of people with lived experience to become educators within tertiary settings. In this paper we present the Valuing Lived Experience Project (VLEP), an initiative led by a Lived Experience Academic (LEA) that seeks to systematically and meaningfully embed lived experience into the social work curriculum at a Western Australian university by providing significant opportunities for the capacity building of both individuals with mental health lived experience and academics. Given the relative infancy of service user involvement in Australian social work education, the VLEP offers a number of opportunities for reflection and consideration. A long-standing partnership between a LEA and Social Work Academic is described, the activities and key learnings of the VLEP to date are outlined, and we offer our reflections on challenges encountered throughout the journey. We hope that our experiences and learnings can be drawn upon to progress lived experience participation in tertiary settings and further legitimise lived experience involvement in the education of social workers.     

Uneven Divestment of the State: Social Reproduction and Sex Work in Neo-developmentalist Argentina

Abstract

Sex work has been identified as an important dimension of the ‘survival circuits’ which have developed in the majority world in the context of neo-liberalisation, as a response to the deepening misery of the Global South. Yet while much research has explored the role of sex work in contexts of ‘neo-liberal’ regimes of capital accumulation, few have paid sustained attention to sex work in regimes which are not purely ‘neo-liberal’. Drawing on data with sex workers across 10 cities in Argentina gathered between 2007 and 2014, this article examines multiple spaces of sex workers' lives, including the workplace, the home, and the state in a context of what has been dubbed ‘neo-developmentalism’. It argues that sex work contributes multiple forms of value and subsidies for the state and capital. First, sex work provides a subsidy in the form of the provision of ‘employment’; second, female sex workers provide unwaged reproductive labour in the family; and third, in the labour movement. Yet despite these three contributions to the reproduction of the working class and therefore of capital, the state undermines sex workers' capacities through violence and sustained repression. The article concludes that the neo-developmentalism has led to ‘uneven divestment of the state’ in the reproduction of particular sections of the working class, namely those outside the formal and ‘productive’ sectors.     

Bingo Regulation and the Feminist Political Economy of Everyday Gambling: In Search of the Anti-Heroic

Abstract

This paper uses bingo—a lottery-style game particularly popular with older working-class women—to take forward feminist political economy debates about the everyday. It highlights consumption and regulation as key to research on everyday political economy, and aims to contribute to studies of gambling as a marker of the everyday within critical political economy. Rather than seeing gambling primarily in terms of vernacular risk-taking, however, it argues that gambling is also a pathway into exploring other, more self-effacing political economies—of entertainment, fundraising, sharing, and ‘having a laugh’. Focusing on three key areas of regulatory dispute (over how to win bingo; who can participate; and what defines the game), the research suggests that players and workers are (re)enabling the diverse, plural nature of bingo as a political economic formulation—involving winning; entertainment; fundraising; care; flirting; and playful speculation—in the face of technological and legal processes aiming to standardize the game’s meaning as commercial gambling.     

Knowledge translation strategies in a community–university partnership: examining local Quality of Life (QoL)

There is a growing interest in quality of life as an integrated approach to addressing key social, environmental and economic determinants of health. The University of Saskatchewan’s Community-University Institute for Social Research, funded by the Social Sciences and Humanities Research Council (grant #410-2004-0669) has examined the process and results of a multi-stakeholder approach to the ongoing sustainability of Saskatoon, Canada as a healthy city with an improving and a more equitably distributed quality of life. Using quantitative and qualitative analysis, together with GIS technology, this research has examined the quality of life across three locales in Saskatoon—representing Low, Middle and High socio-economic status in both 2001 and 2004. The participatory action research approach used in this work ensures the value of the outputs to the stakeholders. Given the strong recognition of the importance of interfacing policy, research and community, and the growing impatience with the limited application of research findings to social and health practices and policies, this project has undertaken four major knowledge translation/transfer strategies, above and beyond the traditional academic channels: (1) engagement of local media on a consistent basis, (2) implementing community policy forums to ensure continued community readiness and uptake, (3) facilitation of and successful functioning of a steering committee, and (4) employment of an action researcher to operate as a policy entrepreneur. This paper will review and discuss each of these strategies and outline the evaluative research being done to document the success of these strategies.

Validity judgments of rumors heard multiple times: the shape of the truth effect

Research on the illusory truth effect has found that repeated presentation of uncertain statements increases validity judgments of those statements. Three experiments explored the shape of the repetition–validity–judgment relationship over multiple repetitions, the mediating role of processing fluency, and the moderating role of dispositional skepticism. Participants read narratives in which different rumors were repeated 0–6 or 0–9 times; validity estimates, processing fluency, and dispositional skepticism were also measured. Validity judgments were logarithmically related to repetitions; this effect was mediated by processing fluency, and moderated slightly by skepticism. Results explore the boundaries of the processing fluency contrast account of the illusory truth effect, suggest a minor role for skepticism, and inform research on belief in rumor (uncertain statements in circulation).
