Estimation of adult stature from fragmentary tibias.

Linear-regression equations derived from measurements of tibial condyles from 100 individuals in the Hamann-Todd Collection retrodicted known stature with a level of confidence comparable to many of the existing stature-estimation techniques. Statures of an independent control group were estimated with similar success. The strong linear relationship that exists between the length of the tibia and the size of the condyles allows adult stature (of American whites and blacks) to be estimated from the proximal tibia. Since complete tibial length is not required, this technique could prove useful in forensic science and archaeological cases where less-than-intact elements are recovered.     

Comparative identity and homogeneity testing of the mtDNA HV1 region using denaturing gradient gel electrophoresis

A denaturing gradient gel electrophoresis (DGGE) assay has been developed for comparative identity and homogeneity testing of the mtDNA HV1 region. A total of 49 pairs of sequences, each pair differing by a single unique polymorphism, were tested to verify the reliability of the assay. Discrimination between all pairings was achieved as judged by the resolution of the mismatch-containing heteroduplexes from the fully base-paired homoduplexes. In all but two pairings, resolution of the fully base-paired homoduplexes was also obtained. Sequence pairs differing by multiple polymorphisms were also tested and resulted in a greater separation between the homo- and heteroduplexes. Additional information derived from the technique includes the identification of co-amplifying contaminating or heteroplasmic samples in the independent samples lanes. Thirteen heteroplasmic samples, six at positions distinct from those analyzed in the pairwise comparison study, were analyzed and the heteroplasmic positions identified unambiguously by sequencing the excised bands. The technique constitutes a conceptually simple, accurate, and inexpensive test for determining whether two sequences match within the mtDNA HV1 region, while providing a more definitive control for the identification of co-amplifying contaminating or heteroplasmic sequences than is presently available.     

The Distributive Politics of Enforcement

Why do some politicians tolerate the violation of the law? In contexts where the poor are the primary violators of property laws, I argue that the answer lies in the electoral costs of enforcement: Enforcement can decrease support from poor voters even while it generates support among nonpoor voters. Using an original data set on unlicensed street vending and enforcement operations at the subcity district level in three Latin American capital cities, I show that the combination of voter demographics and electoral rules explains enforcement. Supported by qualitative interviews, these findings suggest how the intentional nonenforcement of law, or forbearance, can be an electoral strategy. Dominant theories based on state capacity poorly explain the results.     

Prediction of institutional aggression among personality disordered forensic patients using actuarial and structured clinical risk assessment tools: prospective evaluation of the HCR-20, VRS,Static-99, and Risk Matrix 2000

A minority of men and women with intellectual disabilities at times engage in, and are suspected, or convicted, of illegal activity. Recent policy developments in England and Wales emphasise the need to respond appropriately to putative offending risk through the provision of safe and effective community management, treatment, and support services. In line with these concerns, research has focused increasingly on testing the utility of an evolving variety of risk assessment procedures. Here, the authors set out to challenge the repertoire of a number of prominent and/or recently developed risk assessment procedures and the scope of an associated research literature, on the basis that contextual risk factors are receiving insufficient attention in relation to offending among people with intellectual disabilities. Drawing on the wider criminological literature, a novel study is reported that compares key contemporary proximal social and environmental circumstances in the lives of offenders and non-offenders with intellectual disabilities. A contextual risk score is derived, providing statistical support for increased consideration of the impact of relevant social and environmental circumstances. Increased emphasis on key contextual risk factors is recommended to strengthen community service responses to offenders with intellectual disabilities.     

Application of low copy number STR typing to the identification of aged, degraded skeletal remains

Low copy number (LCN) STR typing was successfully applied to four interesting cases during developmental validation of the approach for degraded skeletal remains. Specific questions were addressed in each case, with the acquisition of STR data largely serving as additional confirmatory or investigatory information in any specific situation, and not necessarily providing the definitive evidence to establish identity. The cases involve missing U.S. service members from World War I, World War II, and the Vietnam War. The variety of these cases, in terms of the questions addressed, the age of the remains, and the type of reference material available for comparison, demonstrates the broad utility of LCN STR typing in the identification of degraded skeletal remains from missing persons.     

Public perceptions of white collar crime seriousness: A survey of an Australian sample

During the past decade or so a number of studies in the United States and Canada have offered a challenge to the commonly held belief that the public is indifferent or somewhat ambivalent to white collar criminality. The present research replicated the Rossi et. al., survey in 1972 of the seriousness of 140 offenses to test if similar results were possible in Australia. The results presented here show that the public do perceive these offenses as being serious, and the degree of seriousness depends on the impact of harm particular types of offenses have on victims.
