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.     

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.     

Optimisation of choline testing using Florence Iodine reagent,including comparative sensitivity and specificity with PSA and AP tests

The detection of semen in forensic science is essential in cases of sexual assault but can be problematic in the absence of spermatozoa. Choline is known to occur in high concentrations in seminal fluid and the Florence Iodine test for its detection has been used in forensic science for many years, however very little is documented regarding its sensitivity and specificity in forensic casework. This paper describes the optimisation of the choline Florence Iodine test (FI) and investigates the sensitivity and specificity of the test against different body fluids, food and drink substances, cleaning products and laboratory chemicals. Comparative testing against Acid Phosphatase (AP) and Prostate Specific Antigen (PSA Seratec®) tests is described and shows that the FI test has greater specificity than the PSA test which cross reacts with a number of body fluids.     

Working on the Ground. A Collective Biography of Feminine Subjectivities: Mapping the Traces of Power and Knowledge

In this paper we map the traces of power and knowledge as we read them at play in our own memories and as we make sense of them from a Foucauldian perspective. Our question here is twofold: how might we use Foucault to read our embodied memories of power and knowledge; and how might we use the analysis of those stories to enable us better to see the implications of Foucault's writing for the analysis of subjects' enmeshment in power/knowledge relations? We use as the ground of our analysis our own embodied memories of achieving ourselves as appropriate(d) subjects (as girls and women, in relation to men--fathers, lovers, and husbands). Our trajectory in this paper is double. First, it has been towards uncovering the ways in which girls and women might be said to be powerful, even when they are complicit in their own subjection. Second, it has been to show that when Foucault defines all acts of power to involve the possibility of resistance and freedom, and he takes the opposite, a state of domination, to arise from 'economic, political, or military means', he has not fully acknowledged the extent to which the repeated, minute accretions of everyday practices can generate sedimentations of lines of force that may also be understood as a state of domination.     

Saving more than the children: the role of child-focused NGOs in the creation of southern security norms

The past decade has seen the emergence of ‘new critical discourses’ on security that argue for a widening of the term. This article hopes to add to such discussions by specifically examining the position of children and of the ngos that champion their rights in relation to the evolving security discourse in Southern societies. With this in mind, the first section of the article outlines the role of ngos in the contemporary practice of security. This will serve as an introduction to section two, where the activity of ngos vis-à-vis children will be considered. Such activity raises a number of questions with regard to the usefulness of incorporating children into the security discourse specifically, and to the social construction of ‘children’ generally. These will be outlined in section three. Section four argues for children to be considered as inherent to the creation of Southern security norms, while the final section concludes.
