Seasonal Variation of Carcass Decomposition and Gravesoil Chemistry in a Cold (Dfa) Climate

It is well known that temperature significantly affects corpse decomposition. Yet relatively few taphonomy studies investigate the effects of seasonality on decomposition. Here, we propose the use of the Köppen‐Geiger climate classification system and describe the decomposition of swine (Sus scrofa domesticus) carcasses during the summer and winter near Lincoln, Nebraska, USA. Decomposition was scored, and gravesoil chemistry (total carbon, total nitrogen, ninhydrin‐reactive nitrogen, ammonium, nitrate, and soil pH) was assessed. Gross carcass decomposition in summer was three to seven times greater than in winter. Initial significant changes in gravesoil chemistry occurred following approximately 320 accumulated degree days, regardless of season. Furthermore, significant (p < 0.05) correlations were observed between ammonium and pH (positive correlation) and between nitrate and pH (negative correlation). We hope that future decomposition studies employ the Köppen‐Geiger climate classification system to understand the seasonality of corpse decomposition, to validate taphonomic methods, and to facilitate cross‐climate comparisons of carcass decomposition.     

Following Historical Precedent: An Argument for the Continued Use of Military Professionals as Triers of Fact in Some Humanitarian Law Tribunals

The military commissions at Guantánamo Bay have properlybeen the subject of much legal scrutiny and criticism. Theiruse of military officers as triers of fact, however, meritsfurther consideration. Salim Hamdan may have benefited fromhaving military officers decide his case. His panel was composedof highly educated military professionals who have dedicatedtheir lives in service of the law. Despite their enmity towardsthe accused, these officers were actually in a better positionto be sympathetic and understanding to the Hamdan defence thana civilian jury. The unique aspects of military service andcombat experience will also make them excellent partners withprofessional jurists in future humanitarian law tribunals.     

Testing a rational choice model of “desistance:” Decomposing changing expectations and changing utilities

We argue that a rational choice framework can be used to explain declines in offending from adolescence to young adulthood in two ways. First, subjective expectations of offending can be age graded such that perceptions of rewards decrease and perceptions of risks and costs increase. Second, the marginal (dis)utility of crime may be age graded (e.g., preferences for risks, costs, and rewards). We examine changes in offending from adolescence to young adulthood among a subset of individuals from the Pathways to Desistance Study (N = 585) and employ a nonlinear decomposition model to partition differences in offending attributable to changing subjective expectations (X) and changing marginal utilities (β). The results indicate that both have direct and independent effects on changes in offending over time. The results of a detailed decomposition on the subjective expectations also indicate that differences exist across the type of incentives. That is, the effect of changing expectations is attributed mainly to changes in perceived rewards (both social and intrinsic). Changing expectations of social costs and risk of arrest from offending have weak effects on changes in criminal behavior, which suggests that they must be accompanied by increases in the weight placed on these expectations to promote appreciable declines in offending.     

De Novo Advanced Adult‐Onset Offending: New Evidence from a Population of Federal Correctional Clients

Adult antisocial behavior is almost always predated by delinquency during childhood or adolescence; however, there is also evidence of adult‐onset criminal offending. This study examined this controversial subgroup of offenders using self‐reported and official data from a total population of federal correctional clients selected from the Midwestern United States. Difference of means t‐tests, chi‐square tests, and logistic regression models found that 11.7% of clients had an adult onset of offending and 2.7% of clients (n = 23) had an onset occurring at age 60 years or older. This group—introduced as de novo advanced adult‐onset offenders—had high socioeconomic status, mixed evidence of adverse childhood experiences, and virtually no usage of drugs with the exception of alcohol. These offenders were primarily convicted of social security and white‐collar crimes and evinced remarkably low psychopathology and criminal risk. More research is needed to replicate the phenomenon of de novo advanced adult‐onset offending.     

The Effects of Changes in Dynamic Risk on Reoffending among Serious Juvenile Offenders Returning from Residential Placement

This study examines whether changes in dynamic risk during juvenile justice long-term residential placement affect recidivism. Advancing the work of prior dynamic risk change analyses, we examine a large sample of 11,891 male and 1930 female juvenile offenders while taking methodological steps to ensure successful and non-successful youth (in terms of recidivism) are (statistically) identical at admission. Specifically, we employ propensity score matching on residential placement youth who recidivate post-release and non-recidivists on static risk factors and initial dynamic risk scores assessed at admission to residential placement. Post-matching, changes in dynamic risk factors from initial assessment at admission to exit assessment at release are examined with a focus on whether those changes distinguish recidivists from non-recidivists. Separate analyses are conducted for male and female juveniles. Results indicate that changes in dynamic risk do affect recidivism likelihood, but that different factors matter for males and females. These sex-specific models allow for distinct policy recommendations.     

Crisis (hostage) negotiators weigh in: the skills,behaviors, and qualities that characterize an expert crisis negotiator

This research identified what skills, behaviors, and qualities experienced crisis (hostage) negotiators believe enhance or harm their success during negotiation. 188 negotiators from various countries (primarily United States) voluntarily completed an online survey in which they listed the aforementioned characteristics and reported on various aspects of their own background and behaviors. Open-response questions were coded and quantitative methods revealed what qualities were listed most frequently by negotiators. Active listening, displays of empathy, effective communication, and remaining calm and collected appear at the top of their to-do lists. Conversely, being confrontational, arguing, yelling, and interrupting were reported as behaviors to be avoided. Most negotiators attend trainings multiple times a year and read on the topic of crisis negotiation. About half follow a model during negotiations, typically the FBI’s Behavioral Change Stairway Model. Findings are discussed with relevance to future research directions and improvement of negotiator trainings.     

International terrorism as a force of homogenization? A constructivist approach to understanding cross-national threat perceptions and responses

Has the emergence of international jihadist terrorism led to common threat perceptions and responses in Europe? The article argues that the homogenization thesis is based around a misguided functionalist notion of a single ‘optimal response’ to an alleged new and potentially catastrophic kind of threat with uniform consequences for all ‘Western’ countries. Drawing on insights from different bodies of literature, the article elaborates a theoretical framework to understand variations in threat perceptions vis-à-vis international terrorism and enrich the socio-linguistic securitization approach of Barry Buzan, Ole Wæver and Jaap de Wilde (Security: a new framework for analysis, London: Lynne Reinner, 1998). The article then empirically examines the rise and fall of threat perceptions among selected European publics between 2000 and 2008. Threat perceptions did converge in the aftermath of the 9/11 attacks, but soon afterward started diverging. The article considers the reasons for this finding as well as the implication for the evolution of counter-terrorist policies in the European Union.     

’Not Septimus Now‘: wives of disabled veterans and cultural memory of the First World War in Britain

Much of the writing on gender and the First World War has looked at the ways in which pre-war gender norms were reasserted in British society after the War. The article looks at the experiences of one group of women, the wives of men psychologically disabled by the experience of war, to show how disability could prevent the reassertion of pre-war gender roles. The experiences of these women, as expressed in the disability files created by the Ministry of Pensions, is then compared with the dramatisations of wives of disabled veterans in two post-war novels. This comparison highlights the ways in which such dramatisations turned the figure of the wife of the disabled veteran into a symbol of suffering that may be compared to the similarly symbolic figures of the neurasthenic veteran.
