Gender-Based Violence Prevention Workshops: An Experimental Evaluation of Efficacy

Gender-based violence has become an increasingly visible and salient public problem. In the Fall of 2015, the University of Connecticut’s Violence Against Women Prevention Program (VAWPP) implemented interactive workshops in first-year experience (FYE) classes to reduce rape myth acceptance, improve knowledge and understanding of the University’s affirmative consent policy, and increase confidence in interpreting cues related to sexual consent. This randomized experimental design tested whether these outcomes were realized as a result of the workshops. In almost all instances, the workshops substantially and statistically significantly decreased students’ rape myth acceptance, increased their knowledge and understanding of consent, and improved their confidence in cue interpretation.     

Influence of Velocity on Variability in Gait Kinematics: Implications for Recognition in Forensic Science

Closed circuit television (CCTV) footage is often available from crime scenes and may be used to compare perpetrators with suspects. Usually, the footage comprises incomplete gait cycles at different velocities, making gait pattern identification from crimes difficult. This study investigated the concurrence of joint angles throughout a gait cycle at three different velocities (3.0, 4.5, 6.0 km/h). Six datasets at each velocity were collected from 16 men. A variability range VR throughout the gait cycle at each velocity for each joint angle for each person was calculated. The joint angles at each velocity were compared pairwise, and whenever this showed values within the VR of this velocity, the case was positive. By adding the positives throughout the gait cycle, phases with high and low concurrences were located; peak concurrence was observed at mid‐stance phase. Striving for the same velocity for the suspect and perpetrator is recommended.     

Narcotics at street level in Denmark. A prospective investigation from 1995 to 2000

This article describes an investigation of illicit drugs at street level in six selected police districts in different regions of Denmark. The investigation was carried out during a 6-year period from 1995 to 2000. During the period, a total of 1244 samples were examined, as about 200 samples were seized each year. A total of 94% of the seized samples were familiar drugs: heroin base, heroin hydrochloride, cocaine hydrochloride and amphetamine sulphate. Only 2% of the samples contained designer drugs. From having constituted 53% of the samples in 1995, the frequency of heroin base fell during the period to 27% of the samples in 2000. The frequency of heroin hydrochloride was unchanged. In the same period, the frequency of cocaine hydrochloride increased from 10% of the samples in 1995 to about 25% of the samples in 2000. Apart from a few exceptions, cocaine had the same extension in all regions of Denmark after 1996. Amphetamine was more frequent in the west of Denmark, while heroin hydrochloride was more frequent in central Denmark. The purity of heroin base was lower in the period 1997-1999 than in the other years. During the entire period, the purity of cocaine hydrochloride and amphetamine sulphate fell, while the purity of heroin hydrochloride was unchanged. No significant differences between the various regions of Denmark were detected during the period in the purity of heroin hydrochloride, heroin base, cocaine hydrochloride or amphetamine sulphate. MDMA was the most frequent designer drug, but other types of designer drugs such as MDA and MDE and the less common PMA, PMMA and MBDB were also found.     

Customizing a commercial laboratory information management system for a forensic genetic laboratory

The need for high-throughput laboratories to comply with regulatory requirements makes data management an important aspect of forensic genetics. A Laboratory Information Management System (LIMS) enables efficient workflows and ensures traceability if designed and implemented properly. We customized a commercial LIMS to support STR typing of reference samples according to in-house defined requirements. The customization focused on data validity, traceability and automated solutions.     

Virtual forensic entomology: improving estimates of minimum post-mortem interval with 3D micro-computed tomography

We demonstrate how micro-computed tomography (micro-CT) can be a powerful tool for describing internal and external morphological changes in Calliphora vicina (Diptera: Calliphoridae) during metamorphosis. Pupae were sampled during the 1st, 2nd, 3rd and 4th quarter of development after the onset of pupariation at 23 °C, and placed directly into 80% ethanol for preservation. In order to find the optimal contrast, four batches of pupae were treated differently: batch one was stained in 0.5M aqueous iodine for 1 day; two for 7 days; three was tagged with a radiopaque dye; four was left unstained (control). Pupae stained for 7d in iodine resulted in the best contrast micro-CT scans. The scans were of sufficiently high spatial resolution (17.2 μm) to visualise the internal morphology of developing pharate adults at all four ages. A combination of external and internal morphological characters was shown to have the potential to estimate the age of blowfly pupae with a higher degree of accuracy and precision than using external morphological characters alone. Age specific developmental characters are described. The technique could be used as a measure to estimate a minimum post-mortem interval in cases of suspicious death where pupae are the oldest stages of insect evidence collected.     

Do Debt Levels Influence State Borrowing Costs?

This article reports on research into the possible interest cost penalties when state governments impose increasingly high debt levels on their citizens. The potential effect of debt levels on borrowing costs is a material one, given the large amounts of state debt outstanding. At the same time that government borrowing is heavy, the demand for government obligations also appears to be strong. The authors examine state debt levels and borrowing costs over a six‐year period (2001–2006) and find little evidence of such an effect, despite rapidly growing debt burdens. Those concerned about state debt levels, the authors say, must look to sources other than investors for pressure to reduce debt issuance.     

Computed tomography as routine in connection with medico-legal autopsies

CT-scanning as routine examination before medico-legal autopsy was introduced at the Institute of Forensic Medicine in Copenhagen, Denmark, in December 2002. The present series comprises of 525 medico-legal examinations performed in the year 2003. The purpose is to determine the value of CT-scanning prior to the post-mortem examination. All findings, CT- as well as patho-anatomic findings - more than 4000 - were registered in a database. To increase the clearness, the findings are divided in accordance to regions such as head, thorax, abdomen, pelvis, extremities and vessels and the CT-findings are compared to the patho-anatomic findings, with the purpose to estimate the advantages and disadvantages with the two types of examination. The preliminary results show, that the CT-scanner is superior when it comes to detection of extremity fractures. The scanner has ability in detecting hemorrhages and hematomas, especially, intracranial.     

Changes in Federal Aid and City Finances: A Case Study of Oregon Cities

Federal aid was not found to stimulate spending for cities inOregon during 1984–1989. Oregon cities relied primarilyon their own-source revenues to finance spending increases.The exception was capital spending, where receipt of federalaid in 1989 positively influenced the rate of spending change.This most likely reflected lower spending by those cities thatdid not receive competitive federal grants. The amount of federalaid received is greatly influenced by the grants skill availableto the community. Growth in total direct current spending wassignificantly associated with increases in user fees and charges.A closer look at specific spending categories revealed a hierarchyof reliance on cities' own-source revenues. Cities increaseduser fees and other benefit charges where possible, and seeminglyonly resorted to property-tax increases when these other revenueswere inappropriate.
