Total and Marginal Cost Analysis for a High School Based Bystander Intervention

Costs of providing the Green Dot bystander-based intervention, shown to be effective in the reduction of sexual violence among Kentucky high school students, were estimated based on data from a large cluster-randomized clinical trial. Rape Crisis Center Educators were trained to provide Green Dot curriculum to students. Implementing Green Dot in schools (N = 13) randomized to the intervention, over five years, cost $1.6 M and included start-up ($58 K) and ongoing implementation ($1.55 M). Costs for adding a school ($25,510) were calculated based on the final year, where no start-up costs were incurred. Knowing the $25,510 cost estimate for adding Green Dot may be particularly useful for high school administrators or school boards when they were making economic decisions based on strong evidence of program effectiveness to reduce violence.     

Biological sex variation in bone mineral density in the cranium and femur

Objectives

Sex and age trends in bone mineral density (BMD) play an important role in the estimation of age-at-death (AAD) of unidentified human remains. Current methodologies lack the ability to precisely estimate age in older individuals. In this study, BMD of the cranium and femur measured by DXA were examined to establish their applicability for age estimation in older adults. BMD as measured by DXA, is most commonly used clinically for prediction of osteoporotic fracture risk. We hypothesized that weight-bearing and non-weight-bearing bones, the femur and cranium, respectively, would provide valuable insights for aging.

Juries and Viewpoint Representation

To generate high-quality deliberations, juries should be diverse in terms of not only demographics but also viewpoints. Using data from the Survey of Texas Adults (n = 1380), we examine whether existing processes select for individuals who represent the population on a variety of viewpoint characteristics, particularly whether the process of forming juries selects for people who are more independent-minded versus authority-minded. We find, on average, that those who believe in the importance of speaking English, are less compassionate, support Biblical literalism, and express more concern about the community effects of wrongdoing are more likely to have been former jurors than to not have served. Death penalty support is also modestly predictive of jury membership. Non-jurors rate their neighborhoods as cleaner than do former jurors. Results point to composition effects in the summonsing process and to the possibility that some types of people exempt themselves from this civic obligation.     

Factors associated with contact child sexual abuse in a sample of indecent image offenders

Abstract

This study explored a sample of 244 UK adult male offenders convicted of offences involving indecent images of children (IIOC): 120 had a previous contact child sexual offence (defined as dual offenders) and 124 had no evidence of an offence against a child (defined as non-contact offenders). Offender groups were compared regarding their socio-demographic characteristics, previous convictions and IIOC possession. Key discriminatory factors that differentiated dual offenders were: access to children, previous offence history, sexual grooming and possession of IIOC that depicts similar-aged victims. In contrast, non-contact offenders could be identified from their greater amount and wider range of IIOC possession. The results suggest a homology between Internet behaviours, IIOC possession and victim selection. Implications for law enforcement agencies are discussed in terms of assisting investigative prioritisation by identifying those most at risk of committing sexual abuse against children.     

The preservation needs of public housing

Abstract

The paper examines the preservation needs of public housing from the perspective of its physical condition and its ongoing repair and replacement needs. It begins by examining the range of needs that exist today, including the level of expenditures that would be required to put the stock in working order to meet existing codes, and to ensure the long‐term viability of the development. It then explores the level of expenditures that would be required on an ongoing basis to keep the stock in good repair and to meet future capital and preventive maintenance needs. The final section addresses several important policy issues, including overall funding requirements, the cost‐effectiveness of preservation efforts compared with vouchers and new construction, the special problems of troubled public housing authorities, and the need to establish stronger incentives for capital planning.     

Notes on recent articles

An increasing number of studies in political communication focus on the “sentiment” or “tone” of news content, political speeches, or advertisements. This growing interest in measuring sentiment coincides with a dramatic increase in the volume of digitized information. Computer automation has a great deal of potential in this new media environment. The objective here is to outline and validate a new automated measurement instrument for sentiment analysis in political texts. Our instrument uses a dictionary-based approach consisting of a simple word count of the frequency of keywords in a text from a predefined dictionary. The design of the freely available Lexicoder Sentiment Dictionary (LSD) is discussed in detail here. The dictionary is tested against a body of human-coded news content, and the resulting codes are also compared to results from nine existing content-analytic dictionaries. Analyses suggest that the LSD produces results that are more systematically related to human coding than are results based on the other available dictionaries. The LSD is thus a useful starting point for a revived discussion about dictionary construction and validation in sentiment analysis for political communication.     

Legitimacy through referendum? The nearly successful domino‐strategy of the Eu‐referendums in Austria,Finland, Sweden and Norway

The end of the Cold War made it possible for some neutral countries to join the European Union. However although the European integration promotes economic co‐operation it also reveals problems concerning national and regional identity. In order to legitimise EU‐membership, the new potential member states Austria, Finland, Sweden and Norway conducted referendums on whether or not they should join EU. These referendums, although different in some national aspects, are an example of an international synchronisation of the political establishments. This synchronisation is discussed in light of a ‘Domino‐Strategy’ of the referendums. Furthermore, the article describes some aspects of the referendum campaigns by stressing the importance of geographical differences, organisational standpoints, public opinion and discourse which shows astonishing similarities but also decisive differences.     

The Power of Local Ties: Popular Participation in the Rwandan Genocide

How do ordinary people come to commit genocide against their neighbors? Ethnicity-based approaches cannot explain the different pathways that lead to mass violence or the different forms that participation takes over time and place. In Rwanda, different processes and mechanisms led some to join in the carnage while others resisted. Utilizing Mark Granovetter's concept of “social embeddedness,” this article argues that social ties and immediate social context better explain the processes through which ordinary people came to commit mass murder in Rwanda. Leaders used family ties to target male relatives for recruitment into the killing groups, which were responsible for carrying out the genocide. Ties among members of the killing groups helped to initiate reluctant or hesitant members into committing violence with the group. Finally, ties of friendship attenuated murderous actions, leading killers to help save Tutsi in specific contexts. Which ties became salient depended on the context. In the presence of the killing group or authority(ies), low-level participants (a group I call “Joiners”) tended to go along with the violence. Alone, Joiners often made different choices. The findings in this article are based on data collected during nine months of fieldwork in two rural communities and two central prisons in Rwanda.
