Are Private Schools Better Than Public Schools? Appraisal for Ireland by Methods for Observational Studies

In observational studies the assignment of units to treatments is not under control. Consequently, the estimation and comparison of treatment effects based on the empirical distribution of the responses can be biased since the units exposed to the various treatments could differ in important unknown pretreatment characteristics, which are related to the response. An important example studied in this article is the question of whether private schools offer better quality of education than public schools. In order to address this question we use data collected in the year 2000 by OECD for the Programme for International Student Assessment (PISA). Focusing for illustration on scores in mathematics of 15-years old pupils in Ireland, we find that the raw average score of pupils in private schools is higher than of pupils in public schools. However, application of a newly proposed method for observational studies suggests that the less able pupils tend to enroll in public schools, such that their lower scores is not necessarily an indication of bad quality of the public schools. Indeed, when comparing the average score in the two types of schools after adjusting for the enrollment effects, we find quite surprisingly that public schools perform better on average. This outcome is supported by the methods of instrumental variables and latent variables, commonly used by econometricians for analyzing and evaluating social programs.     

Domestic violence and South Korean women: the cultural context and alternative experiences

The present research contributes to the growing body of cross-cultural research on domestic violence. This is accomplished by answering the question of how severity of intimate partner abuse varies for (1) women incarcerated for the homicides of their male partners (2) abused women who sought domestic violence shelter, short of killing their intimate assailants, and (3) a group of South Korean females outside of domestic violence shelters or prison. The article concludes with a discussion of potential policy implications of the findings as well as promising directions for future research.     

The Availability of Supervision in Routine Mental Health Care

Clinical supervision is an embedded resource for practice quality in community mental health organizations. Supervision has been found to increase provider competence and decrease stress. In addition, supervision has been associated with service user outcomes including decreased depressive symptoms. However, little is known about the availability and nature of supervision in real world settings. The primary aims of this study were to identify available supervision and the extent to which contextual factors are related to that availability. The data source for this study was a multi-state and multi-site (N?=?14) NIMH-funded trial survey of providers (N?=?273). Supervision was measured by hours per week (quantity) and by utilization of best practice activities (content). Univariate, Chi square, independent samples t-tests, and ANOVA analyses were used to assess supervision content and quantity and to examine subgroup differences. Participants reported an average of 2.17 h of supervision per week and 28.6% of participants endorsed best practice content. Supervision quantity varied significantly across sites (p?<?0.05) and program type (p?<?0.05) while content did not. Individual role within the organization had a significant relationship with reported supervision content (p?<?0.001). In these settings, staff in organizations are exercising discretion in how to utilize supervision within the available time. Supervision time also varied by program type, increasing with the intensity of services. Findings demonstrate that reports of availability vary according to position within the organization and the intensity of services within a given program type. Implications for workforce development, access to quality services, and implementation of evidence-based practices are discussed.     

Challenging Dominant Discourses: Peer Work as Social Justice Work

ABSTRACT

People with mental illnesses are overrepresented in the criminal justice system, and discourses concerning the medical model, criminalization, and criminality dominate the intervention landscape for this population. Using a critical postmodern lens, 45 in-depth interviews with peer specialists who had incarceration histories were analyzed to understand how they approach their work. Peer specialists with incarceration histories constructed new identities through their training and peer work by valuing experiential knowledge. Even in the face of power differentials, they challenged dominant discourses directly and indirectly and advocated for various forms of help for the people with whom they worked.     

Hierarchical Bayesian meta-analysis models for cross-platform microarray studies

The development of new technologies to measure gene expression has been calling for statistical methods to integrate findings across multiple-platform studies. A common goal of microarray analysis is to identify genes with differential expression between two conditions, such as treatment versus control. Here, we introduce a hierarchical Bayesian meta-analysis model to pool gene expression studies from different microarray platforms: spotted DNA arrays and short oligonucleotide arrays. The studies have different array design layouts, each with multiple sources of data replication, including repeated experiments, slides and probes. Our model produces the gene-specific posterior probability of differential expression, which is the basis for inference. In simulations combining two and five independent studies, our meta-analysis model outperformed separate analyses for three commonly used comparison measures; it also showed improved receiver operating characteristic curves. When combining spotted DNA and CombiMatrix short oligonucleotide array studies of Geobacter sulfurreducens, our meta-analysis model discovered more genes for fixed thresholds of posterior probability of differential expression and Bayesian false discovery than individual study analyses. We also examine an alternative model and compare models using the deviance information criterion.     

Occupational Cultures and the Embodiment of Masculinity: Hairdressing,Estate Agency and Firefighting

Drawing on data from an Economic and Social Research Council‐funded project, this article explores the implications of different occupational cultures for men's masculine identity. With a focus on embodiment and individual agency, it explores the argument that it is within ‘scenes of constraint’ that gendered identities are both ‘done’ and ‘undone’. In this article we examine embodied experience in occupational cultures commonly stereotyped as ‘masculine’ or ‘feminine’ (hairdressing, estate agency and firefighting), showing how men conform to, draw upon and resist the gendered stereotypes associated with these occupations. What we argue is that gendered conceptions of ‘the body’ need to be differentiated from individual men's embodiment. Instead, processes of identification can be shown to emerge via embodied experiences of particular kinds of gendered body, and in the ways in which men negotiate the perception of these bodies in different occupational contexts.
