A BAYESIAN SIMULATION APPROACH TO INFERENCE ON A MULTI‐STATE LATENT FACTOR INTENSITY MODEL

The influence of economic conditions on the movement of a variable between states (for example a change in credit rating from A to B) can be modelled using a multi‐state latent factor intensity framework. Estimation of this type of model is, however, not straightforward, as transition probabilities are involved and the model contains a few highly analytically intractable distributions. In this paper, a Bayesian approach is adopted to manage the distributions. The innovation in the sampling algorithm used to obtain the posterior distributions of the model parameters includes a particle filter step and a Metropolis–Hastings step within a Gibbs sampler. The feasibility and accuracy of the proposed sampling algorithm is supported with a few simulated examples. The paper contains an application concerning what caused 1049 firms to change their credit ratings over a span of ten years.     

Non-stationary partition modeling of geostatistical data for malaria risk mapping

The most common assumption in geostatistical modeling of malaria is stationarity, that is spatial correlation is a function of the separation vector between locations. However, local factors (environmental or human-related activities) may influence geographical dependence in malaria transmission differently at different locations, introducing non-stationarity. Ignoring this characteristic in malaria spatial modeling may lead to inaccurate estimates of the standard errors for both the covariate effects and the predictions. In this paper, a model based on random Voronoi tessellation that takes into account non-stationarity was developed. In particular, the spatial domain was partitioned into sub-regions (tiles), a stationary spatial process was assumed within each tile and between-tile correlation was taken into account. The number and configuration of the sub-regions are treated as random parameters in the model and inference is made using reversible jump Markov chain Monte Carlo simulation. This methodology was applied to analyze malaria survey data from Mali and to produce a country-level smooth map of malaria risk.     

Schooling the public on boys: the ongoing salience in media representations of the “crisis” in boys’ education

This paper explores the salience of the “crisis” in boys’ education as it is articulated in Australian print media. We will consider the ways in which this crisis is expressed through a gendered language which simultaneously represents boys as “forgotten” by teaching practices thought to be prioritising girls’ learning, and as an equity (disadvantaged) grouping who require specialised teaching methods different from those currently offered within the Australian school system. Further, we will examine the extent to which feminist-inspired reforms in education are either implicitly or explicitly referenced as an explanation for boys’ apparently poor education attainment, and relatedly consider the work of “experts” supporting claims of a pro-feminine bias that adversely affects boys’ learning outcomes, particularly those experts offering neurological or psychological/cognitive findings which assert a biological basis for gender difference. In this context, we argue that rather than advancing gender equity in schools, popular public discourse, as presented in Australian print media, reinforces and perpetuates notions of gender difference and masculine entitlement.     

Choices and life chances: feminism and the politics of generational change

The perception that young women are disengaged from feminist politics has provoked a great deal of tension between feminist generations. Recent feminist research into generational change has largely avoided this tension by focusing on the shifting meanings of feminism and the discrepancy between young women's reluctance to identify as “feminists” and their general acceptance of feminist attitudes toward gender issues. Nevertheless, in an era when gender equity goals seem to be if not slipping backwards then lacking urgency, young women are less likely to identify with a collective feminist politics than are older women. Underpinned by the findings of a major study of the attitudes toward work, family, and retirement of three generations of Australian women, this paper develops an approach that helps explain this reluctance. Drawing on the work of Karl Mannheim, the paper suggests that the cultural currents shaping the consciousness of different generations of women impact significantly on gender identity. The implications of this cultural shift are considered in the context of feminist politics and the contemporary “culture wars.”     

Evidence-based practice in real-world services for young people with complex needs: New opportunities suggested by recent implementation science

There is growing agreement that child and youth services have been slow to implement evidence-based practice (EBP). A variety of interrelated barriers and facilitators of EBP implementation have been recognized and investigated. Key categories include the attitudes of providers, the characteristics of client populations, the characteristics of usual practice, organizational factors, and resource availability. Implementation scientists are investigating these factors, seeking to bridge the gap between clinical science and practice. Much of this work has been conducted in the context of behavioral health services for children and young people. This paper provides a purposeful review of this research from the perspective of decision-makers in agencies serving young people with multiple and complex psychosocial needs. It is argued that major barriers to EBP may be mitigated if ways can be found to transcend the oppositional construction that has characterized the discourses of EBP versus practice wisdom. A conceptual approach to such integration is offered. New lines of implementation research are offering opportunities for practical action by decision-makers consistent with this integrative approach.     

Disseminating research results to kids: practical tips from the Neighbourhoods for Active Kids study

ABSTRACT

Appropriately disseminating results to children are important because it respects the role they played in the research process. Clearly conveying complex messages to children, however, can be challenging and take a substantial amount of time for researchers. This paper reports on the results dissemination processes and accompanying critical reflection, that occurred during Neighbourhoods for Active Kids study – a community-based health research project with 1102 children aged 8–13 years residing in Auckland, Aotearoa/New Zealand. The results dissemination items included: an individual physical activity and food-purchasing behaviour summary, school physical activity and food-purchasing behaviour summary, colouring-in poster, a video, comic, results booklet, school summary report and school data. The results from critical reflection have been developed into five tips for disseminating results to children. The tips are: consult with children and incorporate their feedback throughout; allow space for change and adaptation; meet children where they are at in the digital world and in the physical world; it’s OK to ask for help; and be careful of the words you use. Findings can be used to inform results dissemination activities across a range of social science disciplines.     

Coping and Regulating Emotions: A Pilot Study of a Modified Dialectical Behavior Therapy Group Delivered in a College Counseling Service

Abstract

Objective: To analyze the efficacy of a pilot program, aimed at treating college students with borderline personality disorder (BPD) using short-term, modified group dialectical behavior therapy at an Australian college counseling service (CCS). Participants: Seventeen enrolled college students aged between 18 and 28 (76.5% female), with a diagnosis of BPD completed the program between November 2009 and November 2010. Methods: Participants attended 8 2-hour group therapy sessions, held at the CCS during semester. Participants were assessed for levels of depression, anxiety, BPD traits, and coping strategies, at commencement and completion of the program. Results: There was a reduction in symptoms of depression and BPD traits, and an increase in adaptive coping skills, including problem solving, and constructive self-talk. There was no reduction in anxiety. Conclusions: The findings indicate promise for short-term treatment of college students with BPD. Implications and limitations are discussed, with emphasis on replication with a control group.
