Female and male sex offenders: a comparison of recidivism patterns and risk factors

Few studies have empirically validated the assertion that female and male sex offenders are vastly different. Therefore, utilizing a matched sample of 780 female and male sex offenders in New York State, the current study explored differences and similarities of recidivism patterns and risk factors for the two offender groups. Results suggested that male sex offenders were significantly more likely than female sex offenders to be rearrested for both sexual and nonsexual offenses. However, limited differences in terms of risk factors between female and male sex offenders were found.     

Words count: taking a count of the changing language of British aid

A word analysis of six UK government White Paper policy statements on aid (selected between 1960 and 2006) compares the top 20 words and key word pairs used in each document. Characteristic sentences are composed of the top 20s to represent the spirit of each paper. Results illuminate changes in the content of White Papers on aid, and point to trends in the history of the UK's approach to international development. A characteristic sentence to illustrate the 2005 Paris Declaration on Aid Effectiveness is contrasted with a sentence of words that did not appear in that document. Readers are invited and challenged to identify words they would like to be used and acted on more commonly in development.     

Determinants of Japanese Local Governments' Decisions Concerning Performance-Based Reward Systems for Teachers

This exploratory study asks: What conditions have precipitated or slowed the adoption of a performance-based reward system for teachers by Japanese prefectural governments in charge of human resource management for teachers? Qualitative scrutiny of deliberation processes in two Japanese prefectures suggests that two institutional factors of educational administration—(1) reform orientation and (2) the lack of employee entrenchment—favor the adoption.     

Haplotype analysis of 17 Y-STR loci in a Japanese population

We analyzed 17 Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS438, DYS439, DYS456, DYS458 and DYS464a/b/c/d) in 252 Japanese males using three multiplex PCR typing systems. Two variants were found at DYS385a/b. A total of 244 different haplotypes were observed, of which 239 were found in single individuals. The haplotype diversity for the 17 loci was 0.996.     

Vacuum metal deposition: visualisation of gold agglomerates using TEM imaging

Vacuum metal deposition (VMD) is a well-established technique that can be used for the development of latent fingermarks on a range of polymer surfaces, including polyethylene (PE) bags exposed to harsh environmental conditions. The technique has also proved to be effective on difficult semi-porous surfaces such as the polymer banknotes in circulation in Australia and in an increasing number of other countries. VMD is a two-stage technique. In the first stage, a small amount of gold is deposited under high vacuum onto the exhibit. This is then followed by the deposition, onto the gold layer, of a much thicker layer of zinc. Normal VMD development is characterised by zinc depositing all over the surface except on the fingermark ridges themselves. A phenomenon of reverse development (zinc on the ridges but not on the surface) has been reported by many authors. Recent studies indicated that this phenomenon might occur on low-density polyethylene (LDPE) when the amount of deposited gold is above an optimum quantity. The results suggested that the size of the gold agglomerates formed on the surface of the polymer plays a critical role. This preliminary study was aimed at visualising, by transmission electron microscopy (TEM), the formation of gold agglomerates on polymer surfaces to gain an appreciation of how the density and size of these agglomerates changes with an increasing amount of evaporated gold.
