Quality of web-based information on cannabis addiction

This study evaluated the quality of Web-based information on cannabis use and addiction and investigated particular content quality indicators. Three keywords ("cannabis addiction," "cannabis dependence," and "cannabis abuse") were entered into two popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability, and content quality. "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. Of the 94 Websites identified, 57 were included. Most were commercial sites. Based on outcome measures, the overall quality of the sites turned out to be poor. A global score (the sum of accountability, interactivity, content quality and esthetic criteria) appeared as a good content quality indicator. While cannabis education Websites for patients are widespread, their global quality is poor. There is a need for better evidence-based information about cannabis use and addiction on the Web.     

Creating an Ecology of Hope: Arts-based Interventions with Refugee Children

This paper illustrates how human ecological theory and hope theory were used to develop arts-based research tools and program interventions with refugee children in a Canadian inner city context. Building on key ideas such as: the contextualized, reciprocal, and dynamic nature of hope, the paper identifies a series of program activities. These include the use of photographs, a hope quilt, the development of narratives, followed by opportunities for children to share their hope work with others and for parents and other adults to undertake child-focused and hope-based discussions. Policy and program implications for refugee children are then discussed.

Overcoming fieldwork challenges in urban health research in developing countries: a research note

With rapid growth in the global urban population over the next two decades, health will increasingly have an urban bias. The picture of public health is particularly complex in African cities, where rates of urbanisation, poverty and inequity are high. This paper identifies the main data collection problems encountered within a panel study in low‐income areas of Johannesburg, with special emphasis on sampling, access and partnerships. The paper will be of relevance to anyone considering research in the cities of developing countries, especially in Africa.     

Sexual Coercion within Mixed-Sex Couples: The Roles of Sexual Motives,Revictimization, and Reperpetration

Research suggests that a history of childhood sexual abuse, and previous experiences of sexual coercion, may predict sexual coercion victimization and perpetration. More recently, sexual motivation has been found to correlate with both consensual and non-consensual sexual activity. However, sexual motivation has not been examined in association with previous experiences of abuse and sexual coercion. The aim of this study was to investigate childhood sexual abuse, previous sexual coercion experiences, and sexual motives of both partners as possible risk factors for current sexual coercion victimization and perpetration within a sample of 209 mixed-sex couples. This study examined whether power, stress relief, partner pressure, and imposition motives contributed unique variance to the prediction of sexual coercion beyond that accounted for by past childhood sexual abuse and sexual coercion events. Using hierarchical logistic regressions, four predictive models were examined for both male and female sexual coercion perpetration and victimization. Results show that childhood sexual abuse was only a significant predictor of female sexual coercion perpetration, whereas male sexual coercion victimization and perpetration were predicted by sexual coercion victimization and perpetration in previous relationships. Power motives were also significant predictors of sexual coercion perpetration, and imposition was a significant predictor of sexual coercion victimization for both genders.     

The role of human papillomavirus (HPV)-related stigma on HPV vaccine decision-making among college males

ABSTRACT

Objective: The goals of the present study are (1) to identify sociodemographic and psychosocial predictors of human papillomavirus (HPV)-related stigma and (2) to examine the relationship between HPV-related stigma in predicting HPV vaccine decision-making among college males. Participants: Six hundred and eighty college males aged 18–26 from 3 Canadian universities were recruited from September 2013 to April 2014. Methods: Participants completed a self-report survey assessing HPV-related stigma, psychosocial predictors of HPV-related stigma, and HPV vaccine decision-making. The results were analyzed using variance analyses and linear regressions. Results: Ethnicity, province of residence, and perceived severity of HPV were found to significantly influence HPV-related stigma. In addition, HPV-related stigma was higher in those unaware of the availability of the HPV vaccine for males. Conclusions: Promotion efforts should concentrate on Asian minorities and should avoid HPV severity messaging, as these may lead to higher HPV-related stigma, which in turn may act as a barrier to vaccination.

What are Children's Centres? The Development of CC Services, 2004–20081

Children's centres are intended to be a mainstream, universal service. They began in 2004 and their origins are diverse. Some replaced various forms of local provision, most notably Sure Start programmes; others were established from scratch. Issues for exploratory empirical work have been identified from the guidance issued by central government. Using interview data from three urban local authorities, this article explores the nature of the ‘core offer’ that centres are expected to provide and the way in which they have pursued the goal of integrating staff and services. The article highlights the problems of balancing a focus on the child and on the parent; of reconciling childcare provision as part of the employability agenda and as a means to educational achievement for the child; of permitting local variation while achieving consistency; of the role of monitoring in relation to developing good practice; and of achieving integration in a mixed economy of care. We find that despite the greater specification of the core offer for children's centres compared to that for Sure Start, there are substantial differences between children's centres in terms of services, while the mixed economy of provision poses considerable challenges to the goal of integration.     

An empirical Bayes procedure for the selection of Gaussian graphical models

A new methodology for model determination in decomposable graphical Gaussian models (Dawid and Lauritzen in Ann. Stat. 21(3), 1272?C1317, 1993) is developed. The Bayesian paradigm is used and, for each given graph, a hyper-inverse Wishart prior distribution on the covariance matrix is considered. This prior distribution depends on hyper-parameters. It is well-known that the models??s posterior distribution is sensitive to the specification of these hyper-parameters and no completely satisfactory method is registered. In order to avoid this problem, we suggest adopting an empirical Bayes strategy, that is a strategy for which the values of the hyper-parameters are determined using the data. Typically, the hyper-parameters are fixed to their maximum likelihood estimations. In order to calculate these maximum likelihood estimations, we suggest a Markov chain Monte Carlo version of the Stochastic Approximation EM algorithm. Moreover, we introduce a new sampling scheme in the space of graphs that improves the add and delete proposal of Armstrong et al. (Stat. Comput. 19(3), 303?C316, 2009). We illustrate the efficiency of this new scheme on simulated and real datasets.     

Paternal supervisor gatekeeping: How supervising fathers hinder other fathers at work in their uptake of flexible work arrangements

This study explores the role that supervisors play in the low uptake of Flexible Work Arrangements (FWA) among fathers in France. We draw on 28 interviews with fathers who had requested access to FWA and reported on the reaction of their supervisors. These supervisors were all fathers themselves and had previously benefitted from such arrangements themselves, but did not grant such policies to other fathers. To understand these unexpected findings, we conducted an additional 16 interviews with supervising fathers in organizations who had previously enjoyed similar FWA. The findings show that supervising fathers can act as barriers to other fathers in their organizations who try to push for more gender equality. We identified four ways in which supervisors tend to dissuade fathers from accessing policies to which they are entitled: gender-role confirming discourses; career threats; practical reasons as a justification; and a lack of paternal workplace support. The findings highlight the role of men (in this case, supervising fathers) in the lack of increasing gender equality at work. By showing that fathers can function as ‘paternal supervisor gatekeepers’ for other fathers in their organizations, we open up new fruitful ways for studying gender equality in organizations.
