Statistical Challenges in the Quantification of Gunshot Residue Evidence

The discharging of a gun results in the formation of extremely small particles known as gunshot residues (GSR). These may be deposited on the skin and clothing of the shooter, on other persons present, and on nearby items or surfaces. Several factors and their complex interactions affect the number of detectable GSR particles, which can deeply influence the conclusions drawn from likelihood ratios or posterior probabilities for prosecution hypotheses of interest. We present Bayesian network models for casework examples and demonstrate that probabilistic quantification of GSR evidence can be very sensitive to the assumptions concerning the model structure, prior probabilities, and the likelihood components. This finding has considerable implications for the use of statistical quantification of GSR evidence in the legal process.     

Prosecutorial discretion for domestic violence cases: an examination of the effects of offender race,ethnicity, gender,and age

Much of the existing literature on courts and sentencing has focused on judicial decision-making. Prior research on prosecutorial decision-making is more limited, with even less attention paid to the prosecution of domestic violence cases. The research that has been conducted has produced inconsistent results regarding the effects of legal and extralegal variables. The current study focuses on the effects of extralegal suspect characteristics on the decision to dismiss domestic violence cases in a large Midwestern county from June 2009 to December 2009. The findings demonstrate that gender and race have a strong influence on prosecutors’ decisions to dismiss charges in domestic violence cases. Contrary to the focal concerns perspective, however, the results indicate that males and Black and Hispanic offenders are more likely to have their cases dismissed. Implications for future research are discussed.     

Gaining access or going public? Interest group strategies in five European countries

Interest groups differ in the strategies they use to influence public policy. Some mainly try to gain access (i.e., have direct contact with decision makers), whereas others tend to ‘go public’ by launching campaigns that aim to mobilise the broader public. In this article it is argued that group type – namely the distinction between business associations, professional associations and citizen groups – is a major determinant of the choice of strategy. The effect of group type, however, is conditional on the group's endowment with material resources and the issue context: the differences across group types are largest for resource‐rich associations and associations active in distributive policy fields. Original data from surveys of national associations in five European countries (Austria, Germany, Ireland, Latvia and Spain) enable the assessment of this argument. The theoretical expectations are supported, with the results having relevance for the normative evaluation of political systems and the positive study of interest group influence.     

Sudden death following exercise testing related to abnormalities of the cardiac conduction system and coronary artery pathology

A case of sudden death following exercise testing in a 33-year-old man is reported. The forensic autopsy showed atherosclerotic stenosis of the left coronary artery, as well as some changes in the cardiac conduction system, including anomalies of the atrioventricular node and moderate fibrosis and fatty infiltration of the branching bundle. This case demonstrates that cardiac arrest during vigorous exercise may be multifactorial and that abnormalities of the cardiac conduction system may have played some role in the fatal issue.     

Results of the 2003-2004 GEP-ISFG collaborative study on mitochondrial DNA: focus on the mtDNA profile of a mixed semen-saliva stain

We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.     

Suicide by injection of a veterinarian barbiturate euthanasia agent: report of a case and toxicological analysis

The history and toxicological findings of a suicidal case involving injection of a veterinarian barbiturate euthanasia agent (Vetanarcol containing pentobarbital are presented. Blood pentobarbital concentrations compatible with drug overdose were determined. Almost identical levels were found in blood, cerebrospinal fluid (CSF) and vitreous humour (VH). The highest concentration was measured in the bile. The present case is compared with similar rare cases in the literature.     

Postface: fragmentation,failing trust and enduring tensions over what counts as climate finance

The Paris Agreement commits nations in Article 2(1) to “Making finance flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development.” However there is an absence of internationally agreed accounting rules that would permit overall assessments of progress to this goal and any meaningful comparisons of performance between countries. This is true also for the quantitative Copenhagen/Cancún promise by developed nations to jointly mobilize US$100 billion by 2020. Our goal is to provoke discussion about the depth of the problems this lack of a functional definition and accounting system have created and perpetuated. We do so by describing the fragmented system of national reporting of climate finance and how the OECD’s Rio Marker system is serving neither contributors nor recipients. More than a trust issue between developed and developing countries, we argue that the lack of modalities to account for climate finance also considerably impedes the effective functioning of the bottom-up approach that now prevails under the UNFCCC. The deadline to propose "modalities of accounting climate finance" by 2018 is a crucial window in which to address this chronic issue in international climate policy.     

The moving frontiers of genetically modified soy production: shifts in land control in the Argentinian Chaco

This article attempts to understand how control over land (power in practice) is built, achieved and contested in the context of land transfers involving pressures over possession rights in Santiago del Estero in northern Argentina. Here new forms of land control – due to expansion of the speculative, soy and cattle frontiers – are changing and involve new relationships while using novel mechanisms to gain and maintain control. The article adopts the notion of shifting ‘frontiers of land control’ as an analytical lens, following Lund and Peluso (2011). We can say that the process of soy and cattle expansion into the new frontiers happens through a group of different mechanisms which range from voluntary purchase to violent evictions. As shifts in land control in the frontier involve pressures on possession rights, we observe different mechanisms of control, mainly in the direction of dispossession and enclosure. The paper adds to the debate on ‘land grabbing’ by (a) showing how domestic investors operate to advance industrial agriculture and (b) showing how this frontier advances in a context of (rather unsecured) possession rights where rights are being shifted through transfers (sales, leases, evictions) and compensation mechanisms as well as conflict and judicial procedures.     

Structural Changes to the Public Sector and Cultural Incompatibility: The Consequences of Inadequate Cultural Integration

Structural changes are commonly undertaken to achieve gains, such as enhanced efficiency and performance. In this paper, we explore the cultural issues associated with a structural change in the Australian Public Service. We argue that cultural differences across merged functions were disruptive and challenging to overcome. We posit, however, that these challenges were exacerbated by the lack of systemic effort to integrate cultures, thus impeding synergy realization. Our findings are consistent with the private sector literature that warns mergers and acquisitions undertaken with too much haste and without adequate planning can lead to cultural issues when not managed appropriately.     

CLARE EVANS MEMORIAL ESSAY PRIZE 2006: Liberty,Citizenship and the Suppression of Female Religious Communities in France, 1789–90

This article examines how nuns reacted to the proposed suppression of religious orders by the National Constituent Assembly during the French Revolution. Drawing upon petitions sent to the Assembly by female religious communities, as well as the letters of their individual members, it explores how these women harnessed revolutionary discourse to argue for their rights as citizens, revealing in the process their sentiments towards the religious state. Whether they were happy to leave their convents or professed a desire to stay, their correspondence encapsulates the dilemma faced by the Assembly in determining how to ensure liberty for all without overriding individual rights.
