Where do Bayesian priors come from?

Bayesian prior probabilities have an important place in probabilistic and statistical methods. In spite of this fact, the analysis of where these priors come from and how they are formed has received little attention. It is reasonable to excuse the lack, in the foundational literature, of detailed psychological theory of what are the mechanisms by which prior probabilities are formed. But it is less excusable that there is an almost total absence of a detailed discussion of the highly differentiating nature of past experience in forming a prior. The focus here is on what kind of account, even if necessarily schematic, can be given about the psychological mechanisms back of the formation of Bayesian priors. The last section examines a detailed experiment relevant to how priors are learned.     

Nanotoxicology and Ethical Conditions for Informed Consent

While their strength, electrical, optical, or magnetic properties are expected to contribute a trillion dollars in global commerce before 2015, nanomaterials also appear to pose threats to human health and safety. Nanotoxicology is the study of these threats. Do nanomaterial benefits exceed their risks? Should all nanomaterials be regulated? Currently nanotoxicologists cannot help answer these questions because too little is known about nanomaterials, because their properties differ from those of bulk materials having the same chemical composition, and because they differ so widely in their applications. Instead, this paper answers a preliminary ethical question: What nanotech policies are likely to contribute to society’s ability to give or withhold free informed consent to the potential risks associated with production and use of nanomaterials? This paper argues that at least four current policies appear to jeopardize the risk-disclosure condition that is required for informed consent. These are the funding problem, the conflict-of-interest problem, the labeling problem, and the extrapolation problem. Apart from future decisions on how to ethically make, use, and regulate nanomaterials, this paper argues that, at a minimum, these four policies must be modified. Government must spend greater monies on nanotoxicology; ensure independent nanotoxicology research; label consumer products containing nanomaterials; and avoid assuming that nanotoxicological properties are based merely on mass and chemical composition. Otherwise free informed consent to these new technologies and materials may be jeopardized.     

Inadequate Housing Among Families Under Investigation for Child Abuse and Neglect: Prevalence from a National Probability Sample

This study aimed to estimate the prevalence of inadequate housing that threaten out-of-home placement among families under investigation by child welfare. Data came from the National Survey of Child and Adolescent Well-Being, a nationally representative longitudinal survey of child welfare-involved families. Child protective services caseworkers as well as caregivers provided information on families whose child remained in the home after initial investigation (N = 3,867). Multilevel latent class analyses tested the presence of inadequately housed subgroups using 4 housing problem indicators at baseline. Logistic regressions assessed convergent and predictive validity. A two class latent solution best fit the data. Findings indicated that inadequate housing contributed to risk for out-of-home placement in approximately 16 % of intact families under investigation by child protective services. These families were 4 times more likely to need housing services 12 months later. Federal legislation emphasizes integration of social services as necessary to end homelessness. This study demonstrates overlap across public agencies. Enhanced coordination of child welfare and housing services facilitates interventions to prevent and mitigate homelessness.     

Evaluating Environmental Change Strategies: Challenges and Solutions

In this introductory article we define environmental change strategies (ECS), summarize the primary challenges associated with evaluating ECS, and provide an overview of the methods researchers have employed to begin to address these challenges. This special issue provides a range of examples, from researchers and practitioners in the field, of different approaches for addressing these challenges. These articles present new methods to understand and test how ECS are implemented and propose methods to evaluate their implementation. The content of the articles covers multiple public health issues, including substance abuse prevention, tobacco control, HIV prevention, and obesity prevention. This special issue is intended to build the evidence base for effective ECS, generate compelling discussion, critical analyses, and spur future research that will help improve the implementation and evaluation of ECS.     

Perception and Understanding of Bribery in International Business

This study examines attitudes toward bribery in international business and whether such attitudes differ between men and women. Results of surveys of adults studying for careers in international business indicate ambivalent and nuanced attitudes over bribe giving/taking with significant differences by sex with respect to specific hypothetical situations, suggesting a gender gap on matters of bribery. It is recommended that academic curriculum and management development programs stress ethics and legality and focus on the Foreign Corrupt Practices Act and similar antibribery laws so that aspiring managers are properly trained to recognize and manage the challenges prevalent in conducting business internationally.     

‘The tables have turned’: Sport,emotion & the passive counter-politics of youth citizenship

This article considers the intersections between sport, emotion, and youth citizenship. I explore the emotional dynamics of citizenship of young people, in relation to sport, and within the context of liberal immigration polity in Singapore. In this qualitative study, I conducted video-elicitation written interviews (VEWI) with twenty-two Singaporean youths to understand the multiple ways in which young people negotiate and conceive of their citizenship through emotion, specifically in relation to an emotionally charged sport space. With the 2010 Moscow World Table Tennis Team Championships as the focus of this study, this article explores young people's ‘emotional subjectivities’ of citizenship to make sense of their strategies in articulating resistance through a form of passive counter-politics to top-down power relations of citizenship governance in Singapore. An emergent spatiality of emotional citizenship in relation to spaces of modern sport is identified, contributing to debates in geography and beyond.     

The Impact of Legislative Standards on Batterer Intervention Program Practices and Characteristics

Changes in social policy are often pursued with the goal of reducing a social problem by improving prevention efforts, intervention program practices, or participant outcomes. State legislative standards for intimate partner violence intervention programs have been adopted nearly universally across the US, however, we do not know whether such standards actually achieve the intended goal of affecting programs’ policies and practices. To assess the effect that batterer intervention program (BIP) standards have on policies and practices of programs, this study used longitudinal surveys collected as part of an ongoing evaluation conducted from 2001 to the present to compare intervention program (N = 74) characteristics and practices at three time points before and after the adoption of standards in Oregon. Analyses were conducted to examine all BIPs in Oregon at each time point, as well as change among a subset of programs in existence at all survey assessments. Results indicate that across all programs, the use of mixed gender group co-facilitation increased by 14 % between 2004 and 2008, while program length increased by approximately 12 weeks. However, other practices such as programs’ coordination with community partners were unchanged. Analyses of within-program change revealed fewer differences, with only program length increasing significantly over the three assessments. These and other findings indicate that while standards affected program length as intended, other practices commonly addressed by legislative standards remained unchanged. The findings provide needed information regarding programs’ compliance with components of the standards, the potential need for compliance monitoring, and the potential impact of state standards on program effectiveness and on the prevalence of intimate partner violence.     

Making Sense of Climate Change: How Story Frames Shape Cognition

In 2006, Adam J. Berinsky and Donald R. Kinder published findings in the Journal of Politics that demonstrated that framing news as a story influences how individuals cognitively organize concepts and information. The study presented here moves forward in this tradition. This research combines samples obtained in the springs of 2009 and 2010 while conducting online experiments. In these experiments, slightly over 2,000 respondents are asked to organize concepts presented in one of three culturally nuanced stories about climate change or where information is presented as a list. Hierarchical cluster analysis indicates that when respondents are exposed to culturally congruent stories, respondent organizational patterns are more likely to mirror the story. We discuss the implications of these findings.     

What a Difference Family-Driven Makes: Stories of Success and Lessons Learned

Community Psychology’s emphasis on citizen participation aligns with the nationwide children’s mental health family movement and is clearly evident in communities that have made sustainable system changes. The national family movement has long advocated for the meaningful engagement of families and youth who are the focus population of the federal Children’s Mental Health Initiative. Little rigorous research about the experience of families in leadership positions or of their impact on systems of care has been done. In the absence of scientifically acquired evidence, this article offers the reader a glimpse into the authority, influence and credibility earned by four family leaders as well as their impact on local system of care communities. Their stories occur in four distinct macro level arenas: governance, evaluation, legislative advocacy, and workforce development. In the end, common attributes emerge from their stories, providing anecdotal information useful to identifying the qualities of successful family leadership and their impact on sustainable macro level changes.     

Playing the fool: Activists' performances of emotion in policy making spaces

This paper draws upon dramaturgical concepts from performance studies scholarship to examine how situated performance and context enmesh with the emotional content of the practices of policy making. Drawing on sociological dramaturgical perspectives, the cultural and literary criticism that inspired them, and in particular Bahktin's concepts of the grotesque and heteroglossia, I investigate the subversive use of humour in policy work as a way of revealing “emotional knowledge” about the issues under discussion. First I set out the way “emotion” was understood by participants in an NGO's programme of policy activities as a mode of knowing the world, and how emotion and rationality were embodied in the forums by activists and civil servants respectively. I take as a case study activists “playing the Fool” within a programme of policy work in which I conducted ethnographic research. These performances, once set within a mise-en-scène that includes furniture, smells, lighting and the physicality of the people involved, create complex, unsettling and intersecting networks of meaning about power and knowledge in policy work. I argue that such a dramaturgical approach to interpreting the work of making policy challenges scholars to accurately represent the multiplicity of meanings of “emotion” at play in any context.
