Age at Death Estimation Using Multislice Computed Tomography Reconstructions of the Posterior Pelvis*

Abstract: Thanks to recent advances, computed tomography is now seen as a tool of great value in the field of physical anthropology. In this study, we focused on the posterior pelvis and the auricular surface and evaluated the accuracy of 3D reconstructions of the auricular surface, using a methodology derived from a previous study by Lovejoy et al. We also looked for trabecular bone criteria expressing age‐related changes. Forty‐six coxal bones were scanned, and scoring of macroscopic criteria showed a good agreement between 3D reconstructions and photographs, especially for transverse organization (k = 0.90). The changes occurring in the posterior part of the sacropubic trabecular bundle were evaluated on CT reconstructions via three new criteria, which exhibited a good intra‐ and inter‐observer agreement (k = 0.77–0.89), and were particularly useful in identifying older subjects. We concluded that these CT‐evaluated trabecular bone criteria are promising and yield useful information about age at death.     

The Nordic governments' responses to the Covid-19 pandemic: A comparative study of variation in governance arrangements and regulatory instruments

Government responses to the Covid-19 pandemic in the Nordic states—Denmark, Finland, Iceland, Norway, and Sweden—exhibit similarities and differences. This article investigates the extent to which crisis policymaking diverges from normal policymaking within the Nordic countries and whether variations between the countries are associated with the role of expertise and the level of politicization. Government responses are analyzed in terms of governance arrangements and regulatory instruments. Findings demonstrate some deviation from normal policymaking within and considerable variation between the Nordic countries, as Denmark, Finland, and to some extent Norway exhibit similar patterns with hierarchical command and control governance arrangements, while Iceland, in some instances, resembles the case of Sweden, which has made use of network-based governance. The article shows that the higher the influence of experts, the more likely it is that the governance arrangement will be network-based.     

Interdependence,asymmetric crises,and European defence cooperation

Although international crises are often believed to represent windows of opportunity to strengthen European defence cooperation, recent crises have not seemed to produce a clear convergence of European Union (EU) member states’ security interests. This article seeks to address this puzzle by arguing that European defence cooperation is a response to crises that place European states in a situation of military interdependence. Conversely, asymmetric crises, i.e. crises that affect European states unevenly, encourage those states to maintain their autonomy of action. This theoretical argument is supported by two case studies: the failure of the European Defence Community in the early 1950s and the current difficulties experienced by the EU’s military operations. These two cases illustrate a striking continuity in that, because of (neo)colonial ties in particular, European states are often unevenly affected by international crises, which tends to make defence cooperation less effective.     

Evidence evaluation in fingerprint comparison and automated fingerprint identification systems--modelling within finger variability

Recent challenges and errors in fingerprint identification have highlighted the need for assessing the information content of a papillary pattern in a systematic way. In particular, estimation of the statistical uncertainty associated with this type of evidence is more and more called upon. The approach used in the present study is based on the assessment of likelihood ratios (LRs). This evaluative tool weighs the likelihood of evidence given two mutually exclusive hypotheses. The computation of likelihood ratios on a database of marks of known sources (matching the unknown and non-matching the unknown mark) allows an estimation of the evidential contribution of fingerprint evidence. LRs are computed taking advantage of the scores obtained from an automated fingerprint identification system and hence are based exclusively on level II features (minutiae). The AFIS system attributes a score to any comparison (fingerprint to fingerprint, mark to mark and mark to fingerprint), used here as a proximity measure between the respective arrangements of minutiae. The numerator of the LR addresses the within finger variability and is obtained by comparing the same configurations of minutiae coming from the same source. Only comparisons where the same minutiae are visible both on the mark and on the print are therefore taken into account. The denominator of the LR is obtained by cross-comparison with a database of prints originating from non-matching sources. The estimation of the numerator of the LR is much more complex in terms of specific data requirements than the estimation of the denominator of the LR (that requires only a large database of prints from an non-associated population). Hence this paper addresses specific issues associated with the numerator or within finger variability. This study aims at answering the following questions: (1) how a database for modelling within finger variability should be acquired; (2) whether or not the visualisation technique or the choice of different minutiae arrangements may influence that modelling and (3) what is the magnitude of LRs that can be expected from such a model. Results show that within finger variability is affected by the visualisation technique used on the mark, the number of minutiae and the minutiae configuration. They also show that the rates of misleading evidence in the likelihood ratios obtained for one of the configurations examined are low.     

Public opinion and terrorism: does the national economic,societal and political context Really Matter?

ABSTRACT

For national publics, terrorism is today one of the key policy challenges facing European governments. Yet little is known about whether and how the objective national economic, societal and political context influences public opinion about terrorism. The present article addresses this gap in the current research. Using Eurobarometer data, it is demonstrated that excluding a nation’s level of terrorism, no other objective national economic, societal or political indicator sways public attitudes towards terrorism. Objective national economic, societal and political factors are also found not to impact on the relationship between citizens’ economic conditions and public attitudes towards the same. Our results finally demonstrate that people’s perceived economic, cultural and physical (safety) insecurities tend to be a stronger predictor of these attitudes than the objective national context or (social) class differences. The article then discusses the implications of these ?ndings.     

Notes on contributors

This article investigates the political impact of the introduction of state subsidies to political parties. The arguments for and against subsidising political parties are outlined. Different models of party subsidies, and their regulatory frameworks, are discussed. We find little evidence of a cross‐national impact of the introduction of party subsidies. The subsidies cannot explain the decline in party membership. Nor is there evidence to suggest that the subsidies were introduced as a response to membership decline. There is no support for the allegation that party subsidies lead to the petrification of party systems. The subsidies have not meant that other income sources have lost their significance for political parties.     

The Institutionalization of Al-Qaeda in the Islamic Maghreb (AQMI)

A number of observers have expressed serious concerns that Al-Qaeda in the Islamic Maghreb (AQMI), as it expands in the Sahel, may become strong enough to be a threat to Europe and carry on the global mission of Al-Qaeda as conceived by bin Laden. This fear seems unwarranted. Using institutional analysis to study the AQMI behavioral fluctuations over the last decade, this article argues that AQMI's need to find a compromise between external and internal legitimacy has constrained its behavior. The affiliation of the Algerian terrorists with Al-Qaeda was in many ways a marriage of convenience that created a number of internal contradictions. At the cognitive level, implicit Algerian nationalism to rid the country of its corrupt regime remains at odds with pan-Islamic views shared by Al-Qaeda's leadership. At the normative level, indiscriminate suicide bombing supported by Al-Qaeda is abhorrent to many Algerian terrorists, who construe their mandate in the spirit of the Algerian war of independence where it is their duty to protect civilians. These and other contradictions prevent AQMI from developing a coherent political agenda and thus it is less likely to engage in a long-term conflict against European societies.     

Early Repolarization,Acute Emotional Stress and Sudden Death

We herein report the case of a 36‐year‐old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.
