Family-of-origin factors and partner violence in the intimate relationships of gay men who are HIV positive

This exploratory study examined the prevalence of intimate partner violence in a sample of gay men who are HIV positive. The concept of intergenerational transmission of violence, from family systems theory, provided the basis of this examination. It was hypothesized that men who had witnessed or experienced violence in their families of origin would be more likely to perpetrate or experience violence in their intimate relationships. Perpetration and receipt of abuse were assessed to provide a more comprehensive examination of these relationships. The results of this study indicated that psychological abuse was the most commonly reported form of violence in these relationships. The results also provided partial support for the hypothesized relationship between family-of-origin violence and subsequent violence in an intimate relationship. Implications for future research and intervention are discussed.     

Validation of Tool Mark Comparisons Obtained Using a Quantitative,Comparative, Statistical Algorithm

Abstract: A statistical analysis and computational algorithm for comparing pairs of tool marks via profilometry data is described. Empirical validation of the method is established through experiments based on tool marks made at selected fixed angles from 50 sequentially manufactured screwdriver tips. Results obtained from three different comparison scenarios are presented and are in agreement with experiential knowledge possessed by practicing examiners. Further comparisons between scores produced by the algorithm and visual assessments of the same tool mark pairs by professional tool mark examiners in a blind study in general show good agreement between the algorithm and human experts. In specific instances where the algorithm had difficulty in assessing a particular comparison pair, results obtained during the collaborative study with professional examiners suggest ways in which algorithm performance may be improved. It is concluded that the addition of contextual information when inputting data into the algorithm should result in better performance.     

The twin faces of public sector design

Design thinking has become a popular approach for governments around the world seeking to address complex governance challenges. It offers novel techniques and speaks to broader questions of who governs, how they govern, and the limits of rational instrumentalism in policy making. Juxtaposing design thinking with an older tradition of policy design, this article offers the first critical analysis of the application of design thinking to policy making. It argues that design thinking does not sufficiently account for the political and organizational contexts of policy work. Design thinking also errs in universally privileging one particular policy style over others, and fails to account for the reality of policy mixes. Despite these deficiencies, it is argued that design thinking can inform and enrich governance by helping policy designers produce more adaptable designs, better appreciate the behavioral dynamics of public sector design, and leverage networked approaches to social problem solving.     

Deadly catch: shrimp boat captains as United States Naval Intelligence informants, 1942–1945

During World War II, the United States Navy’s Office of Naval Intelligence (ONI) created a confidential fishermen informants program to ensure the security of the fishing industry vital to the U.S. and its allies and to relay intelligence on enemy military and espionage activity along the coasts. In the Sixth Naval District, headquartered in Charleston, South Carolina, the program relied on shrimp boat captains who volunteered to be confidential observers. Those deemed loyal were indoctrinated, equipped with confidential grid charts and the means and procedures to communicate with case officers, and assigned code names to protect their identity as they fished the Atlantic. Although aspects of this secret domestic counterintelligence program were inherently flawed and provided limited intelligence, it reveals how ONI recruited Americans to engage in domestic spying and provide early warning without devolving into vigilantism.     

Assessing 30 years of Westminster policy advisory system experience

With the 30th anniversary of the policy advisory systems concept on the horizon, it is an appropriate time to reflect further on the concept’s utility, particularly in helping to understand the dynamics of system change and their implications for policy-making. This article provides diachronic analysis of the policy advisory systems in the classic Anglo-Saxon ‘Westminster’ family (Canada, UK, Australia, New Zealand). Analysis focuses on five advisory units: the public service and central agencies, partisan ministerial advisers, external consultants, commissions of inquiry, and select special advisory bodies. The principle research aim is to compare these cases to shed light on advisory system dynamics through identification and analysis of shared and country-specific patterns of PAS change. We argue that the leading dynamics of politicization and externalization often used to characterize how advisory systems change masks idiosyncratic country patterns. We argue that differences in the tempo, intensity, and sequencing of advisory unit (de)institutionalization are clear in these cases and that attention to these dimensions of advisory system change add precision to understanding the organization, operation, and evolution of these systems.     

Application of plant DNA markers in forensic botany: genetic comparison of Quercus evidence leaves to crime scene trees using microsatellites

As highly polymorphic DNA markers become increasingly available for a wide range of plant and animal species, there will be increasing opportunities for applications to forensic investigations. To date, however, relatively few studies have reported using DNA profiles of non-human species to place suspects at or near crime scenes. Here we describe an investigation of a double homicide of a female and her near-term fetus. Leaf material taken from a suspect's vehicle was identified to be that of sand live oak, Quercus geminata, the same tree species that occurred near a shallow grave where the victims were found. Quercus-specific DNA microsatellites were used to genotype both dried and fresh material from trees located near the burial site and from the material taken from the suspect's car. Samples from the local population of Q. geminata were also collected and genotyped in order to demonstrate that genetic variation at four microsatellite loci was sufficient to assign leaves to an individual tree with high statistical certainty. The cumulative average probability of identity for these four loci was 2.06x10(-6). DNA was successfully obtained from the dried leaf material although PCR amplification was more difficult than amplification of DNA from fresh leaves. The DNA profiles of the dried leaves from the suspect's car did not match those of the trees near the crime scene. Although this investigation did not provide evidence that could be used against the suspect, it does demonstrate the potential for plant microsatellite markers providing physical evidence that links plant materials to live plants at or near crime scenes.
