Urban Youth Workers' Use of “Personal Knowledge” in Resolving Complex Dilemmas of Practice

Using narrative inquiry to analyze accounts of how two experienced youth workers handled the potential for gun violence in their organizations, this article argues that youth worker expertise in part is based on personal knowledge derived from childhood neighborhood-based peer groups and participation in youth programs. Expert youth workers draw on personal and professional craft knowledge and move between the rules of youth organizations and the rules of the streets to read people and situations and address the potential for serious violence. Implications for youth worker professional development are raised.     

Switching on,switching off: reflections of a practitioner researcher examining the operational behaviour of police officers

ABSTRACT

Evidence-based policing is rapidly becoming adopted by policing agencies among policing jurisdictions. Many academic programmes have been established in higher education to train police managers in applied criminology. However, there is a lack of literature for police officer practitioner researchers (POPR) who might undertake qualitative research, especially research projects that examine police behaviour. This paper reflects on the changing role of the practitioner-researcher and suggests that police officers undertaking qualitative research need to learn to ‘switch off their police role’ and ‘switch on their researcher role’. The author’s insights are drawn from his own experience of qualitative fieldwork working with police officers from New Zealand Police and South Australian Police.     

Can computed tomography replace or supplement autopsy?

Postmortem computed tomography (PMCT) has been integrated into the practice of many forensic pathologists. To evaluate the utility of PMCT in supplementing and/or supplanting medicolegal autopsy, we conducted a prospective double-blind comparison of abnormal findings reported by the autopsy pathologist with those reported by a radiologist reviewing the PMCT. We reviewed 890 cases: 167 with blunt force injury (BFI), 63 with pediatric trauma (under 5 years), 203 firearm injuries, and 457 drug poisoning deaths. Autopsy and radiology reports were coded using the Abbreviated Injury Scale and abnormal findings and cause of death (COD) were compared for congruence in consensus conferences with novel pathologists and radiologists. Overall sensitivity for recognizing abnormal findings was 71% for PMCT and 74.6% for autopsy. Sensitivities for PMCT/autopsy were 74%/73.1% for BFI, 61.5%/71.4% for pediatric trauma, 84.9%/83.7% for firearm injuries, and 56.5%/66.4% for drug poisoning deaths. COD assigned by reviewing PMCT/autopsy was correct in 88%/95.8% of BFI cases, 99%/99.5% of firearm fatalities, 82.5%/98.5% of pediatric trauma deaths, and 84%/100% of drug poisoning deaths of individuals younger than 50. Both autopsy and PMCT were imperfect in recognizing injuries. However, both methods identified the most important findings and are sufficient to establish COD in cases of BFI, pediatric trauma, firearm injuries and drug poisoning in individuals younger than 50. Ideally, all forensic pathologists would have access to a CT scanner and a consulting radiologist. This would allow a flexible approach that meets the diagnostic needs of each case and best serves decedents' families and other stakeholders.     

Role of orthopedic implants and bone morphology in the identification of human remains

When conventional methods of identification, such as visual recognition and dental comparison, cannot be used to identify a deceased person, it becomes necessary to consider alternative methods. The presence of an orthopedic implant in a body may assist identification if ante-mortem medical records are available for comparison. Another method of identification involves comparison of ante-mortem and postmortem radiographs. Eight cases are reported from Forensic Science SA where the presence of orthopedic implants and/or ante-mortem radiographs were used to try to establish identification. In six cases, positive identification was established, and in two cases with upper limb orthopedic implants, the bones remained unidentified. Manufacturers were unable to provide any information about the distribution and use of the implants that could be of use with identification, as there are no requirements in Australia for individual medical implants to be tracked. Such a system has the potential to aid postmortem identification if serial codes were etched onto implants that could then be traced to manufacturers, surgeons, and recipients of these devices.     

Age assessment by magnetic resonance imaging of the knee: a preliminary study

The authors developed an original magnetic resonance imaging (MRI) staging system for epiphyseal fusion of growth plate maturation of the knee and evaluated its reliability and validity for age assessment of living individuals. A total of 290 MRI scans of the knee were reviewed retrospectively in patients aged from 10 to 30 years old (138 males, 152 females). Five original MRI stages were defined to assess the degree of maturation of the distal femoral and proximal tibial epiphyses. Intra-observer variability was excellent and inter-observer variability was good, demonstrating the reliability and the validity of this original MRI staging system. In both sexes, the changes of growth plates (proximal tibial or distal femoral) were associated with age (p<0.001). Our results agreed with classic data on skeletal maturation of the knee, with globally earlier maturation in females than in males, and also earlier maturation of the proximal tibial epiphysis than of the distal femoral epiphysis. MRI of the knee is an efficient non-invasive method of age assessment, without the disadvantage of X-ray exposure. Further studies with larger groups are needed to support our results.     

Whole body postmortem magnetic resonance angiography

Computed tomography (CT) and magnetic resonance (MR) imaging have become important elements of forensic radiology. Whereas the feasibility and potential of CT angiography have long been explored, postmortem MR angiography (PMMRA) has so far been neglected. We tested the feasibility of PMMRA on four adult human cadavers. Technical quality of PMMRA was assessed relative to postmortem CT angiography (PMCTA), separately for each body region. Intra-aortic contrast volumes were calculated on PMCTA and PMMRA with segmentation software. The results showed that technical quality of PMMRA images was equal to PMCTA in 4/4 cases for the head, the heart, and the chest, and in 3/4 cases for the abdomen, and the pelvis. There was a mean decrease in intra-aortic contrast volume from PMCTA to PMMRA of 46%. PMMRA is technically feasible and allows combining the soft tissue detail provided by MR and the information afforded by angiography.     

An evaluation of expert reports with regard to adherence to current quality standards

In early 2008 the penal system of Lower Saxony established a specialised department responsible for risk assessment regarding all prison inmates in that state. The department generates approximately 200 risk assessment expert reports per year, mainly on questions such as the inmates' aptitude for social therapy, relaxation of imprisonment conditions, and transfer to an open prison. Prof. Dr. Konrad and Dr. Heering (from the Charité's Institute for Forensic Psychiatry) have been accompanying the work of this department scientifically for at least 2 years by offering a scientific exchange and by reviewing random samples of the risk assessments and verifying the application of current standards. It is of particular interest to examine which methods are used and which topics are discussed with the inmates during the exploration for risk assessment expert reports, whether or not standardised risk scales are applied, and finally which conclusions are drawn from the results of the exploration and the information which could be gathered from court and prison files.     

The Transcendence of Violence Across Relationships: New Methods for Understanding Men’s and Women’s Experiences of Intimate Partner Violence Across the Life Course

The notion of transitions is an increasingly central concept in contemporary criminology and such issues are particularly significant in the study of intimate partner violence (IPV). Here, attention focuses on relationship dynamics and movement into and out of relationships for understanding long-term patterns of victimization over the life course. Still, a focus on transitions raises questions about how IPV is patterned over time and across relationships and how this contributes to stability and change in victimization risk over the life span. Our study examines this issue using data from the National Violence Against Women Survey. Findings from latent transition analyses reveal strong evidence for change in victimization experiences across the life course. Among women, those who experienced serious, multifaceted violence are most likely to transition out of relationships followed by transition into subsequent relationships characterized by conflict and aggression and a similar pattern is observed among men. At the same time, men who experience physical aggression in previous relationships are most likely to transition into non-violent relationships, while women with similar experiences are much less differentiated in the types of relationships they enter into. When we account for background characteristics (e.g., respondent’s race, education, and age) and childhood experiences of parental violence, the latter is particularly significant in accounting for exposure to serious IPV in later adulthood. Such findings extend our understanding of how life course transitions connect to violence and offending and highlight processes of continuity and change beyond the traditional focus on criminal offending.     

The electoral consequences of voter ignorance

A great deal of research has suggested that scholarly and popular concerns about low levels of citizen political knowledge are exaggerated. One implication of that research is that political history would have unfolded just as it did even if electorates had been more politically informed. This paper presents evidence that counters these claims, showing an infusion of electorally relevant information in twenty-seven democracies would have likely led to a lot of vote “switching”, ultimately changing the composition of many governments. The paper also directly and systematically examines what we might call the “enlightened natural constituency” hypothesis, which expects lower-income citizens to vote disproportionately for left parties once armed with more political knowledge. While the basic argument about how political ignorance disproportionately affects the left’s natural constituency is not new, the hypothesis has thus far not been tested. The analysis provides provisional support for the hypothesis.
