External Validity in Policy Evaluations That Choose Sites Purposively

Evaluations of the impact of social programs are often carried out in multiple sites, such as school districts, housing authorities, local TANF offices, or One‐Stop Career Centers. Most evaluations select sites purposively following a process that is nonrandom. Unfortunately, purposive site selection can produce a sample of sites that is not representative of the population of interest for the program. In this paper, we propose a conceptual model of purposive site selection. We begin with the proposition that a purposive sample of sites can usefully be conceptualized as a random sample of sites from some well‐defined population, for which the sampling probabilities are unknown and vary across sites. This proposition allows us to derive a formal, yet intuitive, mathematical expression for the bias in the pooled impact estimate when sites are selected purposively. This formula helps us to better understand the consequences of selecting sites purposively, and the factors that contribute to the bias. Additional research is needed to obtain evidence on how large the bias tends to be in actual studies that select sites purposively, and to develop methods to increase the external validity of these studies. © 2012 by the Association for Public Policy Analysis and Management.     

Could Intra‐alveolar Hemosiderin Deposition in Adults be Used as a Marker for Previous Asphyxial Episodes in Cases of Autoerotic Death?

Intra-alveolar hemorrhage and hemosiderin have been cited as possible markers of recent and remote asphyxial events. Little study has been undertaken of the potential significance of intra-alveolar hemosiderin in adults as a potential marker of previous sublethal asphyxial episodes. Ten cases of lethal sexual asphyxia (an entity known to be associated with repetitive sublethal asphyxial episodes) and 20 randomly selected, age- and sex-matched controls had sections of lung stained for hemosiderin. Subsequently, intra-alveolar, iron-containing macrophages were counted. All cases were men (ages 15-50 years; mean 31.8). No significant increase in hemosiderin was found in victims of sexual asphyxia, indicating that asphyxial episodes in sublethal sexual asphyxial activities may not be sufficiently intense or prolonged to cause intra-alveolar hemorrhage or that intra-alveolar hemorrhage in adults is a relatively nonspecific finding. These results do not support intra-alveolar hemosiderin deposition as a marker for previous sublethal asphyxial events in autoerotic asphyxia.     

Effects of prior knowledge and expert statement on belief in recovered memories: an international perspective

We tested the hypothesis that beliefs in the purported attributes of recovered memories of child sexual abuse (CSA) are associated with knowledge of the "recovered/false memory debate", and that such beliefs will be related to assessments of the credibility of statements made by participants in a vignette about CSA. Participants from five countries (the United States, Canada, New Zealand, the United Kingdom and Israel) responded to a questionnaire regarding beliefs about recovered memory as well as self-reported exposure to and knowledge of the debate. In addition, they assessed the credibility of statements made by a daughter (reporting recovery of memories of sexual abuse by her father), her father (denying the allegation and accusing the daughter's therapist of implanting in her false "memories" of abuse), and two experts (each supporting one of the two protagonists). We found that prior knowledge of the debate across countries was linked to beliefs in specific attributes of recovered memories and to a subset of the credibility assessments of statements made by the protagonists and their experts. For individuals, however, credibility assessments were unrelated to knowledge of the debate, but they were related to beliefs about memory recovery. Finally, credibility of the protagonists' statements was differentially associated with those made by the daughter's and the father's experts. The results suggest that whereas familiarity with the debate does not affect the credibility of the statements made by the complainant and the accused, expert testimony does, as has been found in prior research. The psycholegal implications of this conclusion are discussed.     

Identifying pregnant women experiencing domestic violence in an urban emergency department

The article describes characteristics of pregnant women presenting to the Emergency Department (ED) who are experiencing current violence and presented a screening tool to identify pregnant women experiencing violence. Women completed an in-person interview regarding violence, sociodemo-graphic factors, health status, and drug use. Fifteen percent of women reported at least one episode of violence during the pregnancy. Young age (OR = 3.37, 95% CI: 1.79-6.36), current alcohol use (OR = 1.53, 95% CI: 1.06-2.19), current marijuana use (OR = 1.96, 95% CI: 1.32-2.92), less than a high school education (OR = 1.46, 95% CI: 1.01-2.12), and a prior diagnosis of trichomonas (OR = 1.81, 95% CI: 1.20-2.72) were significantly related to experiencing current violence. Screening patients using these five characteristics identified 8 out of 10 women reporting violence (sensitivity = 75.6%). These results identify a set of predictors that may be helpful in identifying pregnant women who are experiencing current domestic violence.     

Reconsidering the relationship between alcohol and lethal violence

Prior event-based research regarding the relationship between alcohol and violence suffers from important limitations, including the absence of a comparison group, an inappropriate comparison group, or a comparison group that could be considered appropriate but does not control for potential confounders. To overcome such limitations, we use a matched pair design. Drawing on interviews with men imprisoned for an aggravated assault or homicide committed in response to a conflict with another man, we examine matched pairs of violent and nonviolent conflicts nested within respondents. The results suggest that guns mediate the relationship between alcohol and lethal male-male violence.     

Pilgrimage to wellness: an exploratory report of rural African American clergy perceptions of church health promotion capacity

Churches serve vital roles in African American communities, where disease burden is disproportionately greater and healthcare access is more limited. Although church leadership often must approve programs and activities conducted within churches, little is known about their perception of churches as health promotion organizations, or the impact of church-based health promotion on their own health. This exploratory study assessed perceptions of church capacity to promote health among 27 rural, African American clergy leaders and report the relationship between their own health and that of their congregation. Results indicate a perceived need to increase the capacity of their churches to promote health. Most common were conducting health programs, displaying health information, kitchen committee working with the health ministry, partnerships outside of the church, and funding. Findings lay the foundation for the development of future studies of key factors associated with organizational change and health promotion in these rural church settings.     

Neoliberalism,Transnational Education Norms,and Education Spending in the Developing World, 1983–2004

Using the case of education, we consider how global cultural and economic forces affect national education spending policies. Our analysis includes both an historical analysis of the construction and transformation of ideas about education at the global level and a statistical assessment of the implementation of conflicting approaches to state education funding within countries. In the historical analysis, we show how the idea of free education, although institutionalized in international law, was subject to powerful challenges from international financial institutions, which advocated user fees for public services, including education. Ultimately, the principle of free education prevailed despite the financial clout behind the opposing view. Using data from poor‐ and middle‐income countries from 1983 to 2004, we also show that the presence of international nongovernmental organizations (INGOs) advocating child rights was linked to an increase in the levels of state funding for education. This suggests that embeddedness in global discourses, as evidenced by country‐specific linkages to INGOs, is critical in making governments more accountable for supporting institutionalized ideas concerning education.     

A qualitative study using a systemic perspective exploring the remediation of abusive interactions in intimate heterosexual couples

Very little attention has been paid to both partners beliefs about why violence in their previously abusive relationship has stopped or significantly reduced despite well-documented details in the research literature outlining the characteristics of both victims and perpetrators. This study aimed to provide some understanding of how each partner believed that the violence has ended. However their answers often were not definitive; instead, they uncovered the complexities in their relationship and their struggle to overcome the uncertainty they have to achieve and maintain successful remediation. The article is based on a qualitative Interpretative Phenomenological Analysis (IPA) study that explored the nature of the relationship between six heterosexual couples before and after a therapeutic intervention for the men perpetrators, which followed the Duluth Model. The study included how they both understood the violence and how they maintained nonviolence in their relationship. The men were notably still in the process of reprocessing their understanding of why they were violent and they needed to further understand their reactions to maintain their nonviolence. The IPA themes provided some understanding of how the participants thought they had a better understanding of the factors that had maintained their relationship since the termination of the intervention. The themes, generated from the interviews provided by the perpetrators and their victims, are explored and some explanations for the successful continuation of their relationship following treatment are suggested. Implications for widening the treatment options for men perpetrators are suggested in addition to providing treatment options for couples who wish to remain within their relationships and need help to identify unhelpful and dangerous patterns of interaction.
