The sinking of the Lusitania: reviewing the evidence.

On the afternoon of 7 May 1915 the Cunard Liner Lusitania was torpedoed by a German U-boat whilst en route to Liverpool. Consequently in sank with the loss of 1,195 lives. A series of investigative and formal research exercises, undertaken in the light of eye-witness accounts of the events surrounding that tragedy, has given rise to a number of hypotheses concerning the loss of this vessel. In this paper all the available evidence concerning the attack, and the one or more explosions that occurred, is summarised. The conclusions regarding the torpedo effects and the most likely causes of the secondary events are reported.     

The collation of forensic DNA case data into a multi-dimensional intelligence database

The primary aim of any DNA Database is to link individuals to unsolved offenses and unsolved offenses to each other via DNA profiling. This aim has been successfully realised during the operation of the New Zealand (NZ) DNA Databank over the past five years. The DNA Intelligence Project (DIP), a collaborative project involving NZ forensic and law enforcement agencies, interrogated the forensic case data held on the NZ DNA databank and collated it into a functional intelligence database. This database has been used to identify significant trends which direct Police and forensic personnel towards the most appropriate use of DNA technology. Intelligence is being provided in areas such as the level of usage of DNA techniques in criminal investigation, the relative success of crime scene samples and the geographical distribution of crimes. The DIP has broadened the dimensions of the information offered through the NZ DNA Databank and has furthered the understanding and investigative capability of both Police and forensic scientists. The outcomes of this research fit soundly with the current policies of 'intelligence led policing', which are being adopted by Police jurisdictions locally and overseas.     

Exploring gender differences in dating violence/harassment prevention programming in middle schools: results from a randomized experiment

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration (any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration, but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to be explored further in future research. Regarding our primary research question, we observed no statistically significant differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators, boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization against dating partners than girls. The implications of these results are discussed.     

Assessing the victim-offender overlap among Puerto Rican youth

Purpose

Knowledge about offenders and knowledge about victims has traditionally been undertaken without formal consideration of the overlap among the two. A small but growing research agenda has examined the extent of this overlap. At the same time, there has been a minimal amount of research regarding offending and victimization among minority youth, and this is most apparent with respect to Hispanics, who have been increasing in population in the United States.

Materials &; Methods

This study explores the joint, longitudinal overlap between offending and victimization among a sample of Puerto Rican youth from the Bronx, New York.

Results

Results indicate: (1) an overlap between offending and victimization that persists over time, (2) a considerable overlap in the number, type, direction, and magnitude of the effect of individual, familial, peer, and contextual factors on both offending and victimization, (3) some of the factors related to offending were only relevant at baseline and not for the growth in offending but that several factors were associated with the growth in victimization, and (4) various risk factors could not explain much of the overlap between offending and victimization.

Conclusions

Theoretical, policy, and future research directions are addressed.     

Research on medical records without informed consent

Observational research involving access to personally identifiable data in medical records has often been conducted without informed consent, owing to practical barriers to soliciting consent and concerns about selection bias. Nevertheless, medical records research without informed consent appears to conflict with basic ethical norms relating to clinical research and personal privacy. This article analyzes the scope of these norms and provides an ethical justification for research using personally identifiable medical information without consent.
