Field reliability of the SAVRY with juvenile probation officers: Implications for training

Two complimentary studies were conducted to investigate the inter-rater reliability and performance of juvenile justice personnel when conducting the Structured Assessment of Violence Risk for Youth (SAVRY). Study 1 reports the performance on four standardized vignettes of 408 juvenile probation officers (JPOs) and social workers rating the SAVRY as part of their training. JPOs had high agreement with the expert consensus on the SAVRY rating of overall risk and total scores, but those trained by a peer master trainer outperformed those trained by an expert. Study 2 examined the field reliability of the SAVRY on 80 young offender cases rated by a JPO and a trained research assistant. In the field, intra-class correlation coefficients were 'excellent' for SAVRY total and most domain scores, and were 'good' for overall risk ratings. Results suggest that the SAVRY and structured professional judgment can be used reliably in the field by juvenile justice personnel and is comparable to reliability indices reported in more lab-like research studies; however, replication is essential.     

Acid phosphatase screening — Wetting test paper or wetting fabric and test paper?

Detecting and locating semen stains is addressed by identifying the associated acid phosphatase activity of semen. The recovery of semen stains is critical as it can, via DNA testing, address the possible source(s) of the semen and may aid in the interpretation of a case. The purpose of these experiments, carried out on behalf of the Body Fluids Forum, was to consider whether wetting the test paper alone or wetting the semen stained fabric and the test paper affected the detection and location of the semen stains on various fabric types, or the subsequent recovery of spermatozoa from these fabrics. It became evident that the preferred approach varied depending on the fabric type being tested but that more often than not, wetting both the fabric and the test paper had a detrimental effect on the recovery of spermatozoa.     

Driving growth: Regulatory reform and expressways in Indonesia

This article uses the case study of Indonesian governments' attempts to construct a 1,000 kilometer toll road through the densest parts of Java to shed light on how governments with a checkered past of enforcing contracts and protecting private property rights go about establishing the requisite regulatory framework to attract private investment for infrastructure. While regulatory reform has taken place in Indonesia, vested interests and power will keep the country's political economy from taking on World Bank-promoted best practice characteristics. Programs that promote private sector participation in infrastructure need to be reconsidered where the main ingredients for these programs' success exist in small measures.     

Institutional Change and Embeddedness: Caste and Gender in Financial Cooperatives in Rural India

ABSTRACT

This article examines the interaction between institutional change and caste and gender embeddedness. It develops a framework for understanding how this interaction takes place. The article presents data on the results of an effort by a non-profit development organization, the Cooperative Development Foundation (CDF), to promote women's cooperatives, grounded in the ideas of mutual self-help and equitable access to services, in rural Andhra Pradesh in India. Using a simple theoretical framework that highlights the multi-level nature of institutional change, and the potential for interactions with embeddedness at one level to affect interactions at other levels, the article presents data showing how particular institutional rules of the cooperatives interacted with caste and gender to shape the overall governance and service delivery practices of these new organizations. In particular, after failed attempts to integrate existing, male-dominated cooperatives with women, the CDF created gender-segregated cooperatives. Data from the women's cooperatives show the creation of mixed-caste organizations, with boards of directors that were fairly representative of their membership, but with presidents that were more likely to be from the higher-castes. Access to financial services shows little caste bias, though lending is through caste-based peer groups. The data suggest that the interaction of embeddedness and institutional change is a process contingent on: a) the strategy taken by the development organization towards embeddedness; b) the nature of the institutional change itself relative to the existing social structure; and c) the effects the interactions between institutional change and embeddedness at different levels have on each other.

Socialism,Economic Development and Planning in Mali, 1960–1968

This article looks at practices of pilferage and bribery among African migrant dock workers in Durban in the 1950s. Many of Durban's dockers regularly engaged in small-scale theft, usually food for personal consumption, but sometimes they also got their hands on bigger and more expensive items or sold the pilfered goods. Many also relied on their social networks to find jobs and did not shy away from bribing izinduna to make sure that they were hired on ships that contained the right goods. Such crimes, which were often not recognised as such by the workers, have often been seen as forms of primitive and individual resistance to proletarianisation. This article, however, argues that these were not just reactive and opportunistic acts, but part of a conscious strategy to combine dock labour with a small business, which allowed several workers to withdraw from the wage labour market altogether.     

Computerized craniofacial reconstruction using CT-derived implicit surface representations

In forensic craniofacial reconstruction, facial features of an unknown individual are estimated from an unidentified skull, based on a mixture of experimentally obtained guidelines on the relationship between soft tissues and the underlying skeleton. In this paper, we investigate the possibility of using full 3D cross-sectional CT images for establishing a reference database of densely sampled distances between the external surfaces of the skull and head for automated craniofacial reconstruction. For each CT image in the reference database, the hard tissue (skull) and soft tissue (head) volumes are automatically segmented and transformed into signed distance transform (sDT) images, representing for each voxel in this image the Euclidean distance to the closest point on the skull and head surface, respectively, distances being positive (negative) for voxels inside (outside) the skull/head. Multiple craniofacial reconstructions are obtained by first warping each reference skull sDT maps to the target skull sDT using a B-spline based free form deformation algorithm and subsequently applying these warps to the reference head sDT maps. A single reconstruction of the target head surface is defined as the zero level set of the arithmetic average of all warped reference head sDT maps, but other reconstructions are possible, biasing the result to subject specific attributes (age, BMI, gender). Both qualitative and quantitative tests (measuring the similarity between the 3D reconstructed and corresponding original head surface) on a small (N = 20) database are presented to proof the validity of the concept.
