Patterns of Trauma Induced by Motorboat and Ferry Propellers as Illustrated by Three Known Cases from Rhode Island*

Abstract: Understanding patterns of trauma is important to determining cause and manner of death. A thorough evaluation of taphonomy, trauma, and bone fracture mechanisms is necessary to reconstruct the circumstances of the death. This study examines the skeletal trauma caused by boat propeller strikes in terms of wound characteristics and location based on three cases from Rhode Island. These case studies review the traumatic characteristics caused by propeller injuries and highlight the anatomic regions most likely to sustain skeletal trauma. With this information, investigators may be able to identify propeller trauma even in severely decomposed remains. The discussion of boat propeller trauma also raises issues regarding how forensic anthropologists and forensic pathologists classify trauma (specifically blunt force vs. sharp) and highlights semantic issues arising in trauma classification. The study also discusses why these propeller cases should be classified as blunt trauma rather than sharp or chop/hack trauma. Ultimately, the authors urge consistency and communication between pathologist and forensic anthropologists performing trauma analyses.     

An investigation into the accuracy and reliability of skull-photo superimposition in a South African sample

One of the aims of forensic science is to determine the identities of victims of crime. In some cases the investigators may have ideas as to the identities of the victims and in these situations, ante mortem photographs of the victims could be used in order to try and establish identity through skull-photo superimposition. The aim of this study was to evaluate the accuracy of a newly developed digital photographic superimposition technique on a South African sample of cadaver photographs and skulls. Forty facial photographs were selected and for each photo, 10 skulls (including the skull corresponding to the photo) were used for superimposition. The investigator did not know which of the 10 skulls corresponded to the photograph in question. The skulls were scanned 3-dimensionally, using a Cyberware? Model 3030 Colour-3D Scanhead scanner. The photos were also scanned. Superimposition was done in 3D Studio Max and involved a morphological superimposition, whereby a skull is superimposed over the photo and assessed for a morphological match. Superimposition using selected anatomical landmarks was also performed to assess the match. A total of 400 skull-photo superimpositions were carried out using the morphological assessment and another 400 using the anatomical landmarks. In 85% of cases the correct skull was included in the possible matches for a particular photo using morphological assessment. However, in all of these cases, between zero and three other skulls out of 10 possibilities could also match a specific photo. In the landmark based assessment, the correct skull was included in 80% of cases. Once again, however, between one and seven other skulls out of 10 possibilities also matched the photo. This indicates that skull-photo superimposition has limited use in the identification of human skeletal remains, but may be useful as an initial screening tool. Corroborative techniques should also be used in the identification process.     

Protection orders protect against assault and injury: a longitudinal study of police-involved women victims of intimate partner violence

The objective of this study was to measure the efficacy of protection orders (POs) in reducing assault and injury-related outcomes using a matched comparison group and tracking outcomes over time. This study was a retrospective review of police, emergency department, family court, and prosecutor administrative records for a cohort of police-involved female IPV victims; all events over a 4-year study period were abstracted. Victims who obtained POs were compared with a propensity-score-based match group without POs over three time periods: Before, During, and After the issuance of a PO. Having a PO in place was associated with significantly more calls to police for nonassaultive incidents and more police charging requests that were of multiple-count and felony-level. Comparing outcomes, PO victims had police incident rates that were more than double the matched group prior to the PO but dropped to the level of the matched group during and after the order. ED visits dropped over time for both groups. This study confirmed the protective effect of POs, which are associated with reduced police incidents and emergency department visits both during and after the order and reduced police incidents compared with a matched comparison group.     

Overcoming the tragedy of super wicked problems: constraining our future selves to ameliorate global climate change

Most policy-relevant work on climate change in the social sciences either analyzes costs and benefits of particular policy options against important but often narrow sets of objectives or attempts to explain past successes or failures. We argue that an ??applied forward reasoning?? approach is better suited for social scientists seeking to address climate change, which we characterize as a ??super wicked?? problem comprising four key features: time is running out; those who cause the problem also seek to provide a solution; the central authority needed to address it is weak or non-existent; and, partly as a result, policy responses discount the future irrationally. These four features combine to create a policy-making ??tragedy?? where traditional analytical techniques are ill equipped to identify solutions, even when it is well recognized that actions must take place soon to avoid catastrophic future impacts. To overcome this tragedy, greater attention must be given to the generation of path-dependent policy interventions that can ??constrain our future collective selves.?? Three diagnostic questions result that orient policy analysis toward understanding how to trigger sticky interventions that, through progressive incremental trajectories, entrench support over time while expanding the populations they cover. Drawing especially from the literature on path dependency, but inverting it to develop policy responses going forward, we illustrate the plausibility of our framework for identifying new areas of research and new ways to think about policy interventions to address super wicked problems.     

Self-Reported False Confessions and False Guilty Pleas among Offenders with Mental Illness

Persons with mental illness may be at risk for false admissions to police and to prosecutors because of the defining characteristics of mental illness, but potentially because of heightened recidivism rates and increased opportunities. We surveyed 1,249 offenders with mental disorders from six sites about false confessions (FCs) and false guilty pleas (FGPs). Self-reports of FC ranged from 9 to 28%, and FGPs ranged from 27 to 41% depending upon site. False admissions to murder and rape were rarely reported. We also examined differences between those claiming false admissions and those not. Minorities, offenders with lengthier criminal careers, and those who were more symptomatic were more likely to have self-reported false admissions than their counterparts.     

Gathering human intelligence via repeated interviewing: further empirical tests of the Scharff technique

Research on investigative interviewing has only recently started to compare the efficacy of different techniques for gathering intelligence from human sources. So far the research has focused exclusively on sources interviewed once, thus overlooking that most sources are interviewed multiple times. The present study attempts to remedy this gap in the literature. Students (N?=?66) took on the role of semi-cooperative sources, holding incomplete information about an upcoming terrorist attack. The sources were informed that they would be interviewed at least once, and that additional interviews might follow. Half of the sources were interviewed on three occasions with the Scharff technique (consisting of five tactics), and the other half was interviewed on three occasions using the so-called direct approach (i.e. open-ended and specific questions). Collapsing the outcome over the three interviews, the Scharff technique resulted in significantly more new information compared to the direct approach. Furthermore, sources interviewed by the direct approach overestimated how much new information they had revealed, whereas the sources interviewed by the Scharff technique underestimated their contribution (although not significantly so). The current study advances previous research by further contextualizing the tests of the efficacy of human intelligence gathering techniques.     

Organizational Justice Comes of Age: Review of the <Emphasis Type="Italic">Oxford Handbook of Justice in the Workplace</Emphasis> Edited by Russell Cropanzano and Maureen Ambrose

The subfield of organizational justice has entered young adulthood. Its scientific achievements from conception to contemporary applications are represented in The Oxford Handbook of Justice in the Workplace, edited by Russell Cropanzano and Maureen Ambrose. The Handbook highlights advances in the field’s theoretical foundations, measurements, and applications. This Handbook follows a decade on the heels of its predecessor, Handbook of Organizational Justice, edited by Jerald Greenberg and Jason Colquitt. In 2005 the justice field was dominated by developmental debates over esoteric definitions of various facets of organizational justice, whereas the present Handbook reflects construct refinement, orientation to detail, and theoretical nuance that comes with maturation. This timely release therefore offers a fitting opportunity to reflect on key trends over the last 10 years and to consider the future of organizational justice research. This collection of comprehensive chapters meticulously compiled by the luminaries of organizational justice shows that organizational justice is still young, developing, and full of potential to influence the world.
