Predictive Soil Provenancing (PSP): An Innovative Forensic Soil Provenance Analysis Tool

Soil is a common evidence type used in forensic and intelligence operations. Where soil composition databases are lacking or inadequate, we propose to use publicly available soil attribute rasters to reduce forensic search areas. Soil attribute rasters, which have recently become widely available at high spatial resolutions, typically three arc‐seconds (~90 m), are predictive models of the distribution of soil properties (with confidence limits) derived from data mining the inter‐relationships between these properties and several environmental covariates. Each soil attribute raster is searched for pixels that satisfy the compositional conditions of the evidentiary soil sample (target value ± confidence limits). We show through an example that the search area for an evidentiary soil sample can be reduced to <10% of the original investigation area. This Predictive Soil Provenancing (PSP) approach is a transparent, reproducible, and objective method of efficiently and effectively reducing the likely provenance area of forensic soil samples.     

Providing services to survivors of domestic violence: a comparison of rural and urban service provider perceptions

Although there is a considerable body of knowledge about domestic violence, a limited proportion focuses on domestic violence in rural settings. Using a nonprobability purposive sampling technique, 93 providers of domestic violence services from rural and urban localities in North Carolina and Virginia were located and asked to complete a self-administered survey soliciting provider perceptions about service consumers, the general public, themselves, and inter- and intra-agency issues. Significant differences were observed between rural and urban providers about service consumer needs and experiences, perceptions about the general public, area resource availability, agency funding, provider training, and worker safety. Implications of these differences are discussed.     

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.     

On the relationships between gender, power control, self-control, and crime

This article bridges the gap between two theories that attempt to explain the gender - crime relationship. Power-control theory posits that power relationships of parents in the public sphere are reflected in their relationship at home. Different kinds of households are thus distinguished by degrees of patriarchy. Differential socialization generates gender differences in crime across households. Gottfredson and Hirschi's general theory purports that low self-control explains all crime across all groups, yet little research explored the link between low self-control and crime both among, as well as between, genders. Linking low self-control and power-control theories, this study examined the relationships gender, power-control, self-control, and crime. Results indicated that while low self-control explained both male and female criminality, the effect of parenting on the development of low self-control was complex; males and females differentially responded to parents' control. The gender-based processes that impact the development of self-control should further be explored.
