Occurrences of flesh flies (Diptera: Sarcophagidae) on human cadavers in Switzerland, and their importance as forensic indicators

From 1993 to 2008, criminal investigations were conducted in the western part of Switzerland with special attention to blowfly and flesh fly species in order to estimate the post-mortem interval when requested by the police authorities. Flesh flies were found in only 33 cases out of 160. Five species of the genus Sarcophaga were identified (S. africa, S. argyrostoma, S. caerulescens, S. similis and S. sp.). The main species found on corpses (larval stage) was S. argyrostoma. The thermal constant (K) calculated for this species in Switzerland is 380.6 ± 16.3 (mean ± S.D.) degree-days. With the exception of S. caerulescens, found three times in the larval stage on corpses, the three other species are of minor forensic importance. S. argyrostoma is found during summer and indoors. This species colonises dead bodies, usually the same day as blowfly species, and it could be used to estimate the post-mortem interval. Other species are discussed in the light of current knowledge on their biology and ecology. It is recommended that voucher material be deposited in a museum, allowing further studies by relevant specialists, thereby helping investigators and avoiding misidentifications.     

DNA-based identification and molecular systematics of forensically important Sarcophagidae (Diptera)

Sarcophagid flies have many characteristics that make them ideal forensic indicators. However, their utility is severely limited because it is difficult or impossible to determine the species of a sarcophagid larva, and in many instances an adult specimen, based on anatomy. We developed a database of mitochondrial DNA sequence data that makes it possible to identify all sarcophagid species likely to be found feeding on a human corpse at an urban location in Canada or the USA. Analyses were based on a 783 base pair region of the gene for cytochrome oxidase subunit one (COI). The species analyzed, including some of no forensic importance that were included for purposes of phylogenetic comparisons, were members of the genera Sarcophaga, Peckia, Blaesoxipha, Rovinia, Wohlfahrtia, Brachicoma (all Sarcophagidae), and Musca (Muscidae).     

Moving Away from the Ideal: The Rational Use of Referendums in the Baltic States

Most theories on the use of referendum focus on its democratic virtues. With this point of reference the article analyses the causes of variation in the use of referendums in Latvia and Lithuania since independence. It shows that the referendum has been part of a rational strategy of political parties. Differences in the degree of polarization within the party systems created different incentive structures. As a result, parties in Latvia followed the defensive decision–controlling strategy, trying to prevent decisions made by the opposition from being carried out, while in Lithuania the parties sought to get their own proposals adopted through the decision–promoting strategy. The results reported in this article do not represent a universal explanation for the use of referendum as it is acknowledged that significant differences do exist between transition countries and consolidated democracies, but they do constitute a first step in new theory building.     

Evaluation of a Health Care Provider Training Program to Identify and Help Partner Violence Victims

This study tested four hypotheses about the impact of a 3-h domestic violence training program with 752 health care providers on attitudes and values related to screening and helping partner violence victims. Hypotheses 1, 2, and 3 were that training would be related to: 1) increased self-efficacy to identify and help partner violence victims, 2) increased endorsement of the role of health care providers and settings for helping partner violence victims, and 3) increased comfort making appropriate community referrals to help partner violence victims. Hypothesis 4 was that training effects would be moderated by prior training and by prior experience with helping a victim. Following training, health care providers reported increased self-efficacy, increased comfort making appropriate community referrals, and increased valuation of health care providers and the health care system as having an important role in stopping domestic violence. Hypothesis 4 was also supported. Prior training and/or experience with an abuse victim predicted smaller changes in the dependent variables. These gains held at a 6-month follow-up. Implications for training curriculum design are discussed, in addition to institutional policy implications for determining the benefits versus costs of universal training, including staff who demonstrate prior training or experience with battered victims. Study limitations and future research directions, including the need to measure performance and policy compliance will also be outlined.     

We've had training, now what? Qualitative analysis of barriers to domestic violence screening and referral in a health care setting

The present study assesses barriers to identification and referral of domestic violence (DV) victims by staff at a health care institution following a 3-hr DV training program in which 752 health care providers participated. Focus groups are conducted with staff in hospital departments that serve a high volume of women. Responses to focus group questions identify system-wide and individual hospital department barriers. These barriers have implications for health care organizations trying to implement DV screening protocols through training alone to change staff behavior in diverse clinical settings. Limitations of this study and future research recommendations are also discussed.
