Violence and trauma: the past 20 and next 10 years

The issues of violence and trauma over the past 20 years have generated a significant amount of research. However, the development of each field has remained, for the most part, exclusive from the other. Therefore, the goal of this article is to address this shortcoming within the literature by responding to three important questions: (a) What is the most important thing we have learned about violence and trauma in the past 20 years? (b) What is the most important thing we need to learn in the next 10 years? and (c) What is the most promising methodological innovation in the past 20 years for the study or treatment of trauma or interpersonal violence? This article concludes that by increasing the discourse between the two fields, both research fields may be better able to develop conceptually, methodologically, and empirically.     

Interrogating genomic diversity of E. coli O157:H7 using DNA tiling arrays

Here, we describe a novel microarray-based approach for investigating the genomic diversity of Escherichia coli O157:H7 in a semi-high throughput manner using a high density, oligonucleotide-based microarray. This microarray, designed to detect polymorphisms at each of 60,000 base-pair (bp) positions within an E. coli genome, is composed of overlapping 29-mer oligonucleotides specific for 60 equally spaced, 1000-bp loci of the E. coli O157:H7 strain EDL933 chromosome. By use of a novel 12-well microarray that permitted the simultaneous investigation of 12 strains, the genomes of 44 individual isolates of E. coli O157:H7 were interrogated. These analyses revealed more than 150 single nucleotide polymorphisms (SNPs) and several deletions and amplifications in the test strains. Pyrosequencing was used to confirm the usefulness of the novel SNPs by determining their allelic frequency among a collection of diverse isolates of E. coli O157:H7. The tiling DNA microarray system would be useful for the tracking and identification of individual strains of E. coli O157:H7 needed for forensic investigations.     

Further investigations into the speed of cerebral swelling following blunt cranial trauma

An anesthetized sheep model of traumatic brain injury (TBI) has been developed to assess early changes in intracranial pressure (ICP) following closed head injury. Immediately after TBI, a transient (<10 min) hypertensive response occurred, followed by significant and prolonged systemic hypotension. ICP demonstrated a biphasic response, being seven times baseline values of 8 ± 2 mm Hg 10 min after injury, decreasing to 25 ± 2 mm Hg by 30 min, and then increasing to values exceeding 30 mm Hg by 4 h postinjury. ICP was always significantly higher than baseline values, which combined with hypotension, reduced cerebral perfusion pressure to less than 60% of normal. This early and sustained increase in ICP after craniocerebral trauma acutely alters cerebral perfusion pressure and brain oxygenation and provides a potential pathophysiological explanation for immediate clinical manifestations in humans following significant TBI.     

Forensic Analysis of mtDNA Haplotypes from Two Rural Communities in Haiti Reflects Their Population History

Abstract: Very little genetic data exist on Haitians, an estimated 1.2 million of whom, not including illegal immigrants, reside in the United States. The absence of genetic data on a population of this size reduces the discriminatory power of criminal and missing‐person DNA databases in the United States and Caribbean. We present a forensic population study that provides the first genetic data set for Haiti. This study uses hypervariable segment one (HVS‐1) mitochondrial DNA (mtDNA) nucleotide sequences from 291 subjects primarily from rural areas of northern and southern Haiti, where admixture would be minimal. Our results showed that the African maternal genetic component of Haitians had slightly higher West‐Central African admixture than African‐Americans and Dominicans, but considerably less than Afro‐Brazilians. These results lay the foundation for further forensic genetics studies in the Haitian population and serve as a model for forensic mtDNA identification of individuals in other isolated or rural communities.     

The effect on reconviction of an intervention for drink-driving offenders in the community

This study reports an evaluation of the Drink-Impaired Drivers program in the English and Welsh probation service. Participants were adult male offenders who had been convicted of a drink-driving offence and were serving community sentences. The 1-year drink-drive reconviction rates were compared for offenders who completed the program, offenders who started but did not complete the program, and a comparison group who were not allocated to the program. At 1-year follow-up, there was no reconviction among offenders who had completed the program. Multivariate analysis showed that the noncompleters had a significantly higher rate of reconviction than the completers and comparison group.     

Judging risk: key determinants in British domestic violence cases

Data from the largest study to date of the working practices of British victim support workers (known as Independent Domestic Violence Advisors or IDVAs) are used to provide insight into how "risk judgments" are made in cases of domestic violence. Using data from more than 2,000 victims, this study found a convergence between actuarial data and IDVAs' risk judgments when the risk score was high, but in cases with a lower risk score, IDVAs often used their professional judgment to upgrade risk. Next, we identified the specific factors underpinning IDVAs' risk judgments. Consistent with existing research, we found that IDVAs relied on a subset of available information when forming risk judgments, and characteristics of the abusive situation, such as the escalation of violence, use of weapons, stalking, and significant injuries, were particularly salient to them. Furthermore, IDVAs paid attention to victims' perceptions and when they felt very frightened or afraid of further injury then IDVAs were more likely to label them as high risk. Although we identified some encouraging overlap between the subset of factors informing risk judgments and those associated with victims' reabuse at a later date, some notable differences indicate a need for messages from research about the significance of particular risk factors to be reinforced to frontline practitioners on a regular basis.     

Doing development differently: Rituals of hope and despair in an INGO

Through an anthropological lens, using examples from working in an international NGO, I explore how and why a group of development workers navigated the coercive practices of aid in ways that benefitted their partners in Africa, Asia, and Latin America. Rather than seeking conspiracies to explain the gaps between development rhetoric and practices, I suggest that people both contest and collude with bureaucratic systems of rule. Youth Rights reformed various rituals and created different management practices internally, as well as maintaining its long-established solidarity approach with partners, but only managed to challenge the donors’ controls to a limited extent.     

Politicization,banking experience and risk in savings banks

During the global financial crisis, criticism of the politicization and lack of professionalization of the savings banks has taken a central position in the political debate. The aim of this article is to analyze if the political presence of governing bodies in Spanish savings banks has been reflected in their various risk-taking behaviors before and during the financial crisis. We will also analyze whether the influence of the chairman’s banking experience matters. The results do not provide evidence that the composition of the boards of savings bank, or even their politicization, have played a role. However we show that savings banks run by a chairman with previous banking experience are likely to be significantly more solvent and less volatile.
