General Versus Specific Predictors of Male Arrest Trajectories: A Test of the Moffitt and Patterson Theories

Developmental taxonomies of crime disagree on whether distinctive offender trajectories are related to common or unique risks. This study examined childhood risks of differing arrest trajectories across childhood through early adulthood (from ages 10–11 to 26–27 years) that were identified in prior work for 203 at-risk, predominantly Caucasian young men. Multivariate analyses revealed that when both distal (childhood risk factors) and proximal risk factors (deviant peer association as a time-varying covariate) were included in the model, relatively few childhood risk factors (assessed at age 9–10 years) discriminated the chronic offender groups from rare offenders (i.e., child antisocial behavior, child attention problems, parents’ antisocial behavior). Rather, deviant peer association was significantly related to levels of offending within each trajectory group (i.e., chronic and rare offender groups). No predictor differentially predicted membership in the two chronic groups, supporting the linear gradation argument. Theoretical and prevention implications are discussed.     

Application of Structured-Light 3-D Scanning to the Documentation of Plastic Fingerprint Impressions: A Quality Comparison with Traditional Photography

Plastic fingerprint impressions found at crime scenes are often too delicate for collection, leaving photography as the best option for documentation. However, traditional photography techniques can be inadequate in documenting minute 3-D details due to limitations of the camera and lighting conditions. This study investigated the feasibility of applying commercially available structured-light 3-D scanners in the documentation of plastic prints. Attempts were made to develop a procedure to extract curvature features from 3-D scanned fingerprints and flatten the friction ridge features into two-dimensional (2-D) images to allow direct comparison with the traditional photography in the CSIpix^® Matcher and NFIQ 2.0 software. Two 3-D scanners were evaluated a Dentsply Sirona inEos X5^® and an Artec Space Spider. In this study, 3-D scanners demonstrated robustness as well as efficiency in the collection of plastic fingerprint impressions in select substrates. One of the developed methods utilizing a discrete geometry operator and convexity features outperformed traditional photography, achieving higher software detection scores in minutiae count and match quality, while traditional photography could not always capture enough high-quality minutiae for comparisons, even after digital enhancement.     

The character and value of vernacular security: the case of South West Cameroon

ABSTRACT

This article reports the findings of field research into the vernacular understanding of security in South West Cameroon. It was found that security significantly contested; it is both objective and subjective; it is communal, whilst at the same time requiring individual l responsibility of personal security; it favours certainty and stability; it draws on a multiplicity of providers, and it goes beyond traditional conceptualisations. The findings make it clear that there are wide divergences between the typical state and donor driven security reform programmes, and people’s perceived security needs. The definition of security is challenged by popular understandings. In addition, though not rejecting the need for state security, it is evident that many more actors are engaged in security provision and personal safety than state actors, and that these actors need to be accounted for in reform programmes. Conclusion draw out advantages of the vernacular approach in security reform programmes.     

The diverse domains of quantified selves: self-tracking modes and dataveillance

The concept of self-tracking has recently begun to emerge in discussions of ways in which people can record specific features of their lives, often using digital technologies, to monitor, evaluate and optimize themselves. There is evidence that the personal data that are generated by the digital surveillance of individuals (dataveillance) are now used by a range of actors and agencies in diverse contexts. This paper examines the ‘function creep’ of self-tracking by outlining five modes that have emerged: private, communal, pushed, imposed and exploited. The analysis draws upon theoretical perspectives on concepts of selfhood, citizenship, dataveillance and the global digital data economy in discussing the wider socio-cultural implications of the emergence and development of these modes of self-tracking.
