An Interactional Perspective of Intimate Partner Violence: An In-depth Semi-structured Interview of a Representative Sample of Help-seeking Women

This article reports a study of women victimized by intimate partner violence (IPV). We describe three interactional aspects of IPV: (1) responses and conduct before, during, and after IPV episodes, (2) impact of alcohol and drug intoxication, and (3) Predictors of risk for IPV victimization in more than one partnership. A representative sample of 157 help-seeking women, recruited from family counseling offices, the police and shelters, were interviewed about physical, psychological and sexual IPV. The nature and characteristics of the IPV interactions were complex and heterogeneous. There were significant interactional differences between the IPV categories concerning the women’s responses and conduct before, during and after the IPV. The impact of alcohol and drug intoxication was relatively small on the occurrence of IPV. About 75% reported that neither the perpetrator nor the female victim had consumed alcohol or drugs before the index IPV exposure. Only 23% of the women had experienced IPV by previous partners. Women who had been subjected to sexual abuse in their family of origin were at almost 25 times increased risk of IPV victimization in more than one partnership. Childhood exposure to physical IPV between parents increased the risk of IPV victimization in more than one partnership significantly more than if the woman had been subject to childhood physical victimization.     

Orphan drug incentives in the pharmacogenomic context: policy responses in the US and Canada

Advances in pharmacogenomic research and increasing industry interest in personalized medicine have important implications for the way that orphan drug policies are interpreted and applied. Concerns have been raised about the potential impact of pharmacogenomics and new genomic technologies on our understanding of how disease categories are delineated, and subsequently, how the concept of rare disease should be defined for the purposes of orphan drug policies. This article considers whether orphan drug legislation can be drafted in a way that will maximize benefits and minimize concerns relating to the impact of pharmacogenomics on orphan drug research and development. After reviewing the issues that may arise at the intersection of orphan drug policies and pharmacogenomics, this article will discuss the potential impact of pharmacogenomics at two critical points: orphan designation and approval of the drug product. At each of these points, the relevant aspects of current US orphan drug legislation are examined, focusing on the extent to which recent amendments may address concerns that have been raised previously. This analysis will then provide the foundation for a critical review and recommendations regarding the proposed new Canadian orphan drug framework.     

Negligent homicide caused by exhaust gas escaping from a manipulated chimney

A chimney built and operated according to the instructions is supposed to ensure that the combustion gases coming from the fireplace can escape safely. If the operational reliability is impaired, this presents a risk of acute poisoning. The report deals with a negligently caused carbon monoxide poisoning of a married couple as a consequence of improper installation of a cover of the chimney opening. Various causes of fatal poisoning due to defective exhaust systems are discussed in connection with the presented case report.     

The Influence of the Relationship and Motivation on Inequity Aversion in Dogs

One crucial element for the evolution of cooperation may be the sensitivity to others?? efforts and pay-offs in comparison with one??s own costs and gains. If an individual responds to a disadvantageous reward distribution, then it would likely increase its relative fitness compared with those who do not (Brosnan & de Waal, Nature 428:140, 2004). Recent experimental research indicates that sensitivity toward unequal reward distribution is not a uniquely human trait; non-human primates react to inequity if they witness a conspecific that obtains a more attractive reward for the same effort. However, primates are not the only species that cooperate and thus would benefit from inequity aversion. Canids also frequently cooperate with group members (e.g., wolves, wild dogs, etc.) or humans (domestic dogs), allowing for the possibility that they also are sensitive to the reward distribution. We report the findings of two studies of dogs?? responses to inequity and the social factors that mediate such responses. In the first study, we investigated whether domestic dogs showed a response to the inequity of rewards received for the same action in pairs of familiar dogs. We found that dogs showed significant behavioral differences when tested without food rewards when in the presence of a rewarded partner compared to the baseline and asocial control situations. This indicated that the presence of a rewarded partner matters (Range, Horn, Virányi, & Huber, Proc Natl Acad Sci USA 106(1):340?C345, 2009). In contrast to primates, dogs did not react to differences in the quality of food or effort. In the second study, we analyzed whether individual (motivational or personality) characteristics determined the response of each subject to unequal reward distributions or whether the subject??s responses depended on the specific relationship they had with its partner. We found that individual motivation and the quality of the relationship influenced the dogs?? performance in test conditions, but that these factors varied across the control and reward inequity conditions. Overall, our results suggest that inequity aversion in dogs is conditional on their and their partner??s rewards. Whether inequity aversion is based on the same mechanisms in both humans and non-human primates is still unclear.
