Ballistic impact of hollow-point ammunition on porcine bone

Identifying failure mechanisms in skeletal tissue allows a deeper understanding of the effects of specific projectile impacts on bone. While ballistic trauma in flat bones is largely researched, knowledge of how long bones react to gunshot impacts is limited in the literature. The impacts of deforming ammunition appear to produce higher levels of fragmentation; however, these have not been studied in depth. This study compares the damage to femora bone by HP 0.357 and 9 mm projectiles constructed with both full and semi-metal jackets. Impact experiments were undertaken on a single-stage light gas gun involving the use of a high-speed video camera and full reconstruction of the bones to ascertain fracture patterns occurring in the femora. Higher degrees of fragmentation are likened to the presence of semi-jacketed HP projectiles than jacketed HP projectiles. The observations of external facing beveled edges are believed to be associated with the increased separation of the jacket and lead core of projectiles. Additionally, experimentation has shown that the amount of kinetic energy lost postimpact is likely related to the presence or the absence of a metal jacket on an HP projectile. The observed data, therefore, suggest that the composition, rather than the configuration, of a projectile affects the type and extent of the damage.     

Driving Legislators' Policy Preferences: Constituent Commutes and Gas Taxes

Understanding differential policy costs across constituencies, and how they link to legislators' policy preferences, can facilitate policy changes that solve pressing problems. We examine the role of policy costs on constituents by studying legislator support for taxing gasoline. Analysis of survey responses from US state legislators, as well as of their voting records, shows that legislators whose constituents would be most affected by an increased gas tax—those whose constituents have longer commutes—are more likely to oppose higher gas taxes. Separately estimating the impact of time spent driving to work versus using public transit shows that the effect of commute times comes from those who have long drives, not from those who ride public transit, highlighting how the policy costs to constituents is a major driver in legislators' considerations. We finish the article by discussing the implications of our findings for combating climate change and for understanding policy feedbacks.     

Displaying Garbage: Installations as Spaces of Domination and Resistance

Abstract

Contemporary artistic installations presenting the detritus of everyday life are an increasingly popular method of raising awareness of what we produce, consume, and throw away. As social critique, these displays examine the political and economic causes and consequences of waste production and resulting ecological degradation. Drawing on Herbert Marcuse’s conceptions of aesthetics, liberation, and ecology in capitalism, this article attempts to discern where we might find hope, encouragement, and active imagination of another possible future through artistic installations. This article cautions that garbage art may both open and close off creative and imaginative spaces for transformation to a liberated society. Differentiating between two categories of art installations, this article explores how installations can reflect back to us our complicated relationship with waste and consumer culture, raising questions as to how the aesthetic realm might serve as a springboard for critique of capitalism.     

Moving from nos/otros to nosotros: a transcendent approach to sustainable development

Traditional top-down approaches to community development reinforce nos/otros binaries within provider/recipient relationships; transcendent approaches, on the other hand, create space for nosotros collaborative development. This article describes an instance of the nos/otros binary, in which a foreign volunteer in a rural community in Ecuador assumed the role of practitioner and limited community members’ roles to recipients or beneficiaries of her development projects. Inspired by findings from this experience, the article presents a case study highlighting an alternative, transcendent, nosotros approach in Albuquerque, New Mexico, where community members work together to imagine, implement, and sustain projects.     

When and why is civil society support “made-in-America”? Delegation to non-state actors in American democracy promotion

One of the United States’ main strategies of democracy promotion involves supporting civil society abroad. According to original data, most of the money spent by the United States on that task supports American NGOs working abroad rather than local NGOs in transitioning and non-democratic countries. Yet there are also significant variations across countries in donor officials’ reliance on American NGOs. Why do American donor officials fund American NGOs as a strategy of aiding democracy abroad more in some cases than in others? This paper argues that donor officials find it easier to observe American NGOs than other NGOs and that American NGOs are more likely to share donor officials’ preferences. Donor officials are therefore more likely to pursue a strategy of “made-in-America” democracy support in countries that are salient for U.S. foreign policy. Evidence from a new data set of democracy assistance programs supports the argument. The findings have implications for the study of American foreign policy, foreign aid effectiveness, and NGOs in world politics.     

Lesbian Spanners: A Re-appraisal of UK Consensual Sadomasochism Laws

There continues to be legal invisibility of lesbians as sexual beings; in particular, for those lesbians who engage in BDSM. A cursory glance at work both within and outside of the academy gives the impression of increased social and legal acceptability for those who engage in BDSM. However, I suggest that this acceptance is illusory and that instead, gay men who engage in BDSM experience increased legal supervision and increased invisibility for lesbians. These issues are examined in the context of two seemingly disparate legal events. The first is the 30 year anniversary of Operation Spanner and the second is the introduction of the Audiovisual Media Services Regulations 2014. Amongst other things, the 2014 Regulations criminalise the portrayal of female ejaculation (but not male). Given this criminalisation of certain kinds of female sexual pleasure, the potentiality to significantly adversely impact upon lesbians is clear. 2017 will be the 30 year anniversary of Operation Spanner and the subsequent focus has been primarily upon gay male BDSM. I speculate as to the possible legal reaction(s) to a lesbian ‘spanner’ BDSM event. I speculate as to the legal reactions to an all-female BDSM dungeon.     

12-Month Prevalence,Trends, Gender Differences,and the Impact of Mental Health Services on Intimate Partner Violence Perpetration Among Discharged Psychiatric Inpatients

Minimal research has examined partner violence committed by individuals with severe mental illness. This study examined rates of IPV in the first year post-discharge from psychiatric hospitalization, trends over time, gender differences, and the impact of follow-up mental health services. One in five (20.3 %) patients committed at least one act of IPV in the first year. Whereas women were more than twice as likely to perpetrate IPV, men were nearly twice as likely to be violent toward non-family members. Risk of IPV was highest immediately post-discharge and decreased over time, with the sharpest decline after 20 weeks in the community. Mental health treatment was associated with a 40 % decrease and medication non-adherence a 50 % increase in risk for IPV. Partner violence is a prevalent concern among discharged psychiatric patients, and these findings suggest that coordinated risk management efforts should focus on the time immediately following hospital discharge.     

Intimate Partner Violence Involving Children and the Parenting Role: Associations with Maternal Outcomes

The aim of the present study was to investigate intimate partner violence (IPV) involving children and the parenting role (e.g., preventing an intimate partner from providing parental care or threatening to take one’s children away). Specifically, the study examined whether this form of IPV affects maternal functioning above and beyond other IPV experiences. Participants included a community sample of 120 primarily low-income, single women, diverse in age, education, and ethnicity, who were interviewed 1 year after giving birth, as part of a longitudinal study. IPV involving children and the parenting role was significantly associated with other experiences of IPV, especially general psychological IPV. Multiple regression analyses revealed that this form of IPV significantly affected mothers’ personal, relational, and parental functioning. Results suggest that it is important to assess for IPV involving children and the parenting role when working with mothers. More research on this unique type of IPV is needed.
