Dealing with allelic dropout when reporting the evidential value in DNA relatedness analysis

A method is suggested that allows the use of loci that have shown allelic dropout in kinship analysis as used for disaster victim identification (DVI) and missing person work (MP). This approach uses an extension of a previously published approach to modelling allelic dropout. This method may salvage some information in cases where allelic dropout is hindering DVI or MP work particularly in reconciliations involving a large number of bodies and pedigrees. It should not replace the pursuit of more complete DNA profiles by the normal rework process for such samples.     

Community juvenile arbitration: An alternative in judicial administration

Congestion in trial courts continues to create a dilemma in judicial administration. In Florida, an effort to address this problem in the juvenile justice system emerged with legislative authorization of community arbitration programs. Implementation came in a joint endeavor of a community and a university to develop a juvenile arbitration program. Assessment of the program in reduction of caseload, cost efficiency, recidivism, reduction of delay prior to hearing, and volunteer participation suggests that community arbitration can be a viable alternative.     

Manners of Death in Drug‐Related Fatalities in Florida

To understand the mortality patterns among drug users and potential risk factors, we evaluated drug‐related deaths reported to the Florida Medical Examiners Commission from 2001 to 2013, by substances, demographics, and manner of death. The annual drug‐related fatalities increased by 57% from 2001 to 2013 (total n = 100,882); 51.8% were accidental, 7.9% homicide, 18.6% natural, and 19.6% suicide. The different manners of death exhibited distinct demographic profiles and drug composition. The gender gap was more prominent in homicide. Age ≥55 years was more closely associated with natural death and suicide. Age <35 years and central nervous system (CNS) stimulants including amphetamines and cocaine showed higher relative risks for accidental death and homicide, whereas CNS depressants including benzodiazepines, carisoprodol, opioids, and zolpidem were more strongly associated with accidental death and/or suicide. The findings aid in identifying populations more vulnerable to drug‐related deaths, developing targeted interventions and thereby improving efficiency of preventive efforts.     

An integrated exploration of factors associated with psychological distress among older prisoners

This paper compares the contributions of socio-demographic, health, mental health, social and environmental factors in explaining variations in psychological distress among older prisoners in two Australian states. One hundred and seventy-three prisoners (aged 50+ ) from 8 Australian prisons were interviewed using the Kessler Psychological Distress (K10) Scale. Three regression analyses were conducted to compare different models of 14 variables significantly associated with psychological distress. Independent variables most prominently associated with variations in psychological distress among older inmates were self-reported levels of social support, self-reported safety and ease of health care access. Difficulties in the built environment and mental health history were significantly explanatory of variations in older prisoner distress in two of the three models. The findings suggest that modifiable situational factors evident in current prison contexts are reasonably explanatory of variations in prisoner distress among older inmates.     

Linking ammonium nitrate-aluminum (AN-AL) post-blast residues to pre-blast explosive materials using isotope ratio and trace elemental analysis for source attribution

Forensic science practitioners are often called upon to attribute crimes using trace evidence, such as explosive remnants, with the ultimate goal of associating a crime with a suspect or suspects in order to prevent further attacks. The explosive charge is an attractive component for attribution in crimes involving explosives as there are limited pathways for acquisition. However, there is currently no capability to link an explosive charge to its source via post-blast trace residues using isotope ratios or trace elements. Here, we sought to determine if pre-blast attribution signatures are preserved after detonation and can be subsequently recovered and detected. A field study was conducted to recover samples of post-blast explosives from controlled detonations of ammonium nitrate-aluminum (AN-Al), which were then analyzed via isotope ratio mass spectrometry (IRMS) and inductively coupled plasma-mass spectrometry (ICP-MS) for quantitation and profiling of isotopes ratio and trace element signatures, respectively. Oxygen and nitrogen isotope ratios from AN-Al yielded some of the most promising results with considerable overlap within one standard deviation of the reference between the spreads of pre- and post-blast data. Trace element results from AN-Al support the findings in the isotope ratio data, with 26 elements detected in both pre- and post-blast samples, and several elements including B, Cd, Cr, Ni, Sn, V, and Zn showing considerable overlap. These preliminary results provide a proof-of-concept for the development of forensic examinations that can attribute signatures from post-blast debris to signatures in pre-blast explosive materials for use in future investigations.

Guilt and the origins of modern law

Abstract

Tracing the history of legal concepts from the decline of European feudalism to the Reformation, this paper examines ways in which the concept of guilt shaped the first evolution of modern law, and it claims that the early revolutionary junctures in the construction of the law were centred around specific and distinctive conceptions of guilt. It argues that, through the history of medieval and early-modern European society, the law learned positively to abstract and account for itself through internally formative exchanges over the subject of guilt, and changes in law's observation of guilt reflected a growing refinement in law's societal sensibility, in its inclusivity, in its patterns of imputation and in its positive powers of self-legitimation. Guilt formed the term around which the law enacted the necessary stages of its social adaptation and produced constructs to underwrite the requirement for general, abstracted and positively inclusive law that constitutes modern society. The ultimate result of guilt's evolution as a legal figure became visible in the fact that the law progressively intensified its positivity and inclusivity, and it amplified the legal and normative resources that it permitted modern societies to store, utilize and reproduce.     

Notes on Contributors

This article draws from a major research project examining the impact of various forms of municipal consolidation in Australia and New Zealand. Its wide-ranging research involved studies of 15 cases of different forms of consolidation, including amalgamation, together with a series of interviews with senior practitioners from the local government sector. Data revealed little evidence of consistent economies of scale from consolidation, however both case studies and interviews indicated that consolidation generated economies of scope and what may be termed ‘strategic capacity’. While it was not possible to disaggregate the data for particular sizes of local authority, enhancement of strategic capacity was more obvious through processes of consolidation in larger ones and less so in smaller, more remote ones.     

Book reviews

This article addresses whether there are differences in regulatory regimes in the devolved nations of the UK. It focuses on the divergence between rhetoric and practice around improving performance of local authorities. By discussing general understanding of public sector quality and the possible role for regulators in ensuring quality it shows that Scotland and Wales have developed different approaches since devolution of power in 1999. By comparing case studies from each of the nations it shows that practices vary much less than could be expected based on the previous research. This is likely to be due to shared underlying assumptions about performance and how to improve it, rather than the regulatory regimes themselves. It is argued that external pressure and support are vital, and that these functions can be damaged by reducing involvement of the state in safeguarding quality of public service delivery.
