Postmortem Computed Tomography in Firearm Homicides: A Retrospective Case Series,

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.     

Evaluating the Potential for Unintentional Occupational Exposure to Fentanyl and Fentanyl Analogues Among Medicolegal Death Investigators and Autopsy Technicians

Recent increases in deaths in the United States from synthetic opioids such as fentanyl and fentanyl analogues (fentanyls) have raised concerns about possible occupational exposures to these potent agents. Medicolegal death investigators and autopsy suite staff might perform job tasks involving exposure to fentanyls. The potential for exposure to fentanyls among medicolegal death investigators and autopsy technicians at a state medical examiner's office was evaluated through review of caseload characteristics, injury and illness logs, and procedures and policies and discussions with management and employee representatives. The evaluation showed that this medical examiner's office had low potential for work-related exposure to fentanyls; its standard operating procedures and personal protective equipment requirements should reduce the potential for occupational exposure. Medicolegal death investigation agencies can develop and implement guidance to control exposures and provide workforce education and training to reduce the potential for work-related exposure to fentanyls.     

The Scharff technique: training military intelligence officers to elicit information from small cells of sources

ABSTRACT

Studies have demonstrated the efficacy of the Scharff technique for gathering human intelligence, but little is known about how this efficacy might vary among different samples of practitioners. In this training study we examined a sample of military officers (n?=?37). Half was trained in the Scharff technique and compared against officers receiving no Scharff training. All officers received the same case file describing two sources holding information about a terrorist attack. University students (n?=?74) took the role of the semi-cooperative sources. Scharff-trained officers adhered to the training as they (1) aimed to establish the ‘knowing-it-all’ illusion, (2) posed claims as a means of eliciting information, and (3) asked fewer explicit questions. The ‘untrained’ officers asked many explicit questions, questioned the reliability of the provided information, pressured the source, and displayed disappointment with the source's contribution. Scharff-trained officers were perceived as less eager to gather information and left their sources with the impression of having provided comparatively less new information, but collected a similar amount of new information as their untrained colleagues. The present paper both replicates and advances previous work in the field, and marks the Scharff technique as a promising technique for gathering human intelligence.

Can We Make Accurate Long-term Predictions About Patterns of De-escalation in Offending Behavior?

This study consists of a comparative analysis of patterns of de-escalation between ages 17–18 and 32, based on data from two well-known prospective longitudinal studies, the Cambridge Study in Delinquent Development (a study of 411 working-class males in London) and the Montreal Two Samples Longitudinal Study (a sample of 470 adjudicated French-Canadian males). Analyses focus on within-individual change, with individuals serving as their own controls. In this regard, the magnitude of measured change is relative to the past degree of involvement in offending. These results are contrasted with predictors of between-individual differences in offending behavior at age 32. We investigate the respective roles of cognitive predispositions and social bonds in the prediction of patterns of de-escalation, and assess whether it is possible to make relatively long-term predictions (over a 15-year period) about offending in adulthood. Findings suggest that traditional measures of social bonds and cognitive predispositions measured at age 17–18 are generally weak predictors of de-escalation up to age 32. However, these measures are stronger predictors of between-individual differences in offending gravity. These findings highlight the difficulties in making accurate long-term predictions about changes in individual offending patterns early in the criminal career.

Childhood and Adolescent Predictors of Late Onset Criminal Careers

This study explores the emergence of a criminal career in adulthood. The main hypothesis tested is that late criminal onset (at age 21 or later) is influenced by early factors that delay antisocial manifestations. The Cambridge Study in Delinquent Development (CSDD) was used to examine early determinants of criminal behavior. 400 Inner London males were followed from ages 8–10 to 48–50, and were classified as follows: 35 late onsetters who were first convicted at age 21 or later, and did not have high self-reported delinquency at ages 10–14 and 15–18; 129 early onsetters first convicted between ages 10 and 20; and 236 unconvicted males. Odds ratios and logistic regression analyses revealed that the best predictors of late onset offenders compared with early onset offenders included nervousness, having few friends at ages 8–10, and not having sexual intercourse by age 18. The best predictors of late onset offenders compared with nonoffenders included teacher-rated anxiousness at ages 12–14 and high neuroticism at age 16. It is concluded that being nervous and withdrawn protected boys against offending in adolescence but that these protective effects tended to wear off after age 21. These findings show that adult offending can be predicted from childhood, and suggest that early intervention might prevent a variety of maladjustment problems and difficulties in adult life.

A Qualitative Analysis of Vietnamese Adolescent Identity Exploration Within and Outside an Ethnic Enclave

Focusing on identity development explorations enables a greater understanding of contexts that affect immigrant adolescents. Utilizing thematic and grounded narrative analysis of 46 journal writings, during a one-month period, from first and second generation Vietnamese adolescents ranging in age from 15 to 18 (26 residents of a culturally and politically active ethnic enclave in Southern California; 20 adolescents living outside the enclave), this study establishes ways in which a focus on social context and exploration processes illuminates the complexity of immigrant adolescents’ identity formation. The two groups shared many similarities, including precipitants to exploration and steps undertaken to explore identity. However, two factors—social and cultural influences and emotional reactions—revealed interesting contrasts distinguishing enclave from non-enclave dwelling Vietnamese adolescents. Data also suggested that immigrant adolescents strive to integrate different domains of identity (ethnicity, gender, career) both with one another and with the historical, social, and cultural contexts they occupy.

Who Votes for the Future? Information,Expectations, and Endogeneity in Economic Voting

Voters’ four primary evaluations of the economy—retrospective national, retrospective pocketbook, prospective national, and prospective pocketbook—vary in the cognitive steps necessary to link economic outcomes to candidates in elections. We hypothesize that the effects of the different economic evaluations on vote choice vary with a voter’s ability to acquire information and anticipate the election outcome. Using data from the 1980 through 2004 US presidential elections, we estimate a model of vote choice that includes all four economic evaluations as well as information and uncertainty moderators. The effects of retrospective evaluations on vote choice do not vary by voter information. Prospective economic evaluations weigh in the decisions of the most informed voters, who rely on prospective national evaluations when they believe the incumbent party will win and on prospective pocketbook evaluations when they are uncertain about the election outcome or believe that the challenger will win. Voters who have accurate expectations about who will win the election show the strongest relationship between their vote choice and sociotropic evaluations of the economy, both retrospective and prospective. Voters whose economic evaluations are most likely to be endogenous to vote choice show a weaker relationship between economic evaluations and their votes than the voters who appear to be more objective in their assessments of the election. Economic voting is broader and more prospective than previously accepted, and concerns about endogeneity in economic evaluations are overstated.     

Governance in the Age of Digital Media and Branding

The politicization of government communications requires intense control. Centralization of government power accompanies advances in information and communications technology, as political elites use branding strategy in an attempt to impose discipline on their messengers and on media coverage. The strategic appeal of public sector branding is that it replaces conflicting messages with penetrating message reinforcement. Among the notable features are central control, a marketing ethos, a master brand, communications cohesiveness, and message simplicity. Together these features work to conflate the party government and the public service, which perpetuates trends of centralization. Using Canada's Conservative government (2006–2015) as a case study, public sector branding explains the hyper control over government communications and demonstrates why these developments can be expected to last, regardless of which party or leader is in control.
