Suicide with inert gases: addendum to Final Exit

Suicide by asphyxiation with a plastic bag placed over the head is a method that has been advocated by right-to-die groups. Recently, such groups have proposed the introduction of helium into the plastic bag as a means of hastening death. Helium is readily available at toy stores, where it is sold in tanks for balloon inflation. It produces asphyxiation by the exclusion of oxygen in enclosed spaces. We report 7 fatalities throughout an 18-month period involving plastic bag suffocation in conjunction with helium use. These fatalities coincide with publication of an update to a popular right-to-die text in which this method is described. Although right-to-die literature was absent from all scenes, this method was not previously observed in our jurisdiction, and the deaths likely reflect exposure to this information. Because of analytical difficulties in testing for helium in biologic specimens, death certification rests on scene investigation.     

The role of the bar context and social behaviors on women's risk for aggression

The present study is an initial examination of the extent to which the environmental characteristics of bars and social behaviors that women engage in when drinking in this setting are associated with bar-related aggression. As expected, several environmental characteristics (e.g., young patrons, pool playing) and social behaviors (e.g., alcohol consumption, leaving the bar with strangers) were associated with more severe bar-related aggression experienced by women during the past year. These results shed light on the significant problem of bar-related aggression against women and can potentially be used to develop prevention and educational programs.     

Explaining Explanations: How Legislators Explain their Policy Positions and How Citizens React

Legislators claim that how they explain their votes matters as much as or more than the roll calls themselves. However, few studies have systematically examined legislators’ explanations and citizen attitudes in response to these explanations. We theorize that legislators strategically tailor explanations to constituents in order to compensate for policy choices that are incongruent with constituent preferences, and to reinforce policy choices that are congruent. We conduct a within‐subjects field experiment using U.S. senators as subjects to test this hypothesis. We then conduct a between‐subjects survey experiment of ordinary people to see how they react to the explanatory strategies used by senators in the field experiment. We find that most senators tailor their explanations to their audiences, and that these tailored explanations are effective at currying support—especially among people who disagree with the legislators’ roll‐call positions.     

Application of Enhanced Point Estimators to a Sample of In Vivo CT‐derived Facial Soft Tissue Thicknesses

Facial approximations based on facial soft tissue depth measurement tables often utilize the arithmetic mean as a central tendency estimator. Stephan et al. (J Forensic Sci 2013;58:1439) suggest that the shorth and 75‐shormax statistics are better suited to describe the central tendency of non‐normal soft tissue depth data, while also accommodating normal distributions. The shorth, 75‐shormax, arithmetic mean, and other central tendency estimators were evaluated using a CT ‐derived facial soft tissue depth dataset. Differences between arithmetic mean and shorth mean for the tissue depths examined ranged from 0 mm to +2.3 mm (average 0.6 mm). Differences between the arithmetic mean plus one standard deviation (to approximate the same data points covered by the 75‐shormax) and 75‐shormax values ranged from ?0.8 mm to +0.7 mm (average 0.2 mm). The results of this research suggest that few practical differences exist across the central tendency point estimators for the evaluated soft tissue depth dataset.     

Intimate Partner Abuse among African American Lesbians: Prevalence, Risk Factors, Theory, and Resilience

The purpose of this article is to present an intersectionality-based model for conceptualizing the risk factors associated with intimate partner abuse (IPA) among African American lesbians. The available literature on prevalence and risk factors associated with IPA suggests that: (a) estimates of prevalence rates for African American lesbian IPA could range from 25?% to 40?%, with the higher end of the range representing the inclusion of nonphysical forms of abuse (i.e., verbal abuse, intimidation, and coercion); and (b) the risk factors most likely to be associated with IPA for this population include poverty, history of trauma and mental health symptoms (including substance abuse), in addition to distress caused by multiple and intersecting forms of oppression (i.e., racialized, classist sexism and heterosexism). The model demonstrates the manner in which all of these risk factors intersect to create disproportionately high risk for this underresearched and underserved population. A psychodynamically based model is also presented that illustrates the cycle of abuse within an African American lesbian relationship. Finally, a model depicting the most likely protective factors segues into a brief concluding discussion about the implications for intervention, prevention, policy, education, and future research.     

Comparative Metropolitan Organization: Service Production and Governance Structures in St. Louis (MO) and Allegheny County (PA)

For many observers, a large number of governments in a metropolitanarea is thought to equate to "fragmentation," and fragmentation,to ineffective organization and poor performance. Other observersfind a large number of local governments to mean competitionand consequent pressures for efficiency. The number of localgovernments, however, is only one dimension of the structureof a metropolitan area. We identify and measure key structuralcharacteristics of "fragmented " metropolitan areas, employinga comparative study of two metropolitan city-counties: St. LouisCityand County, Missouri, and Allegheny County (Pittsburgh),Pennsylvania. We argue that these areas, with their many unitsof local government, "work" by means of integrating structuresbuilt by local governments together with county and state governments.Counties, in particular, are a useful focus for study of metropolitanrelationships because they often provide the institutional framewithin which integrating structures are built.
