Thyroid Cartilage Ossification and Multislice Computed Tomography Examination: A Useful Tool for Age Assessment?

Abstract: Many authors have studied the thyroid cartilage ossification process using radiographic features for age estimation of individuals. Their results were various: Sugiyama reported excellent correlation coefficients between ossification rates and civil age, unlike most other authors. We hypothesized that recent advances in imaging techniques would enable more precise evaluation of the ossification of the thyroid cartilage. We retrospectively analyzed the CT scans of 312 French patients using postprocessing software to examine the pattern of thyroid cartilage ossification, calculating the ossified volume of the cartilage on 3D reconstructions. Pearson’s correlation coefficients for volume were 0.73 for men and 0.75 for women (standard error 18.02 and 17.06), indicating considerable inter‐individual variability. Although a correlation between civil age and morphological changes was found, these methods based on thyroid cartilage ossification were not accurate enough for the assessment of individual age.     

The political economy of infrastructure development in Africa: an assessment of the NEPAD Presidential Infrastructure Champion Initiative (PICI)

Using a political economy approach, this article examines the factors that cause high-profile political leaders on the African continent to champion particular regional infrastructure projects within the framework of the Presidential Infrastructure Champion Initiative (PICI). It also analyses the extent to which the presence of high-stature political champions enhances the prospects for project implementation. The paper argues that the economic and integrative potential of regional infrastructure projects, alongside the presence of high-stature political champions, do not necessarily guarantee implementation. Rather, it is the interplay of diverse economic, institutional and political factors and interests that determines the successful implementation, or otherwise, of the various championed infrastructure projects.     

Does contact with the justice system deter or promote future delinquency? Results from a longitudinal study of British adolescent twins

What impact does formal punishment have on antisocial conduct—does it deter or promote it? The findings from a long line of research on the labeling tradition indicate formal punishments have the opposite-of-intended consequence of promoting future misbehavior. In another body of work, the results show support for deterrence-based hypotheses that punishment deters future misbehavior. So, which is it? We draw on a nationally representative sample of British adolescent twins from the Environmental Risk (E-Risk) Longitudinal Twin Study to perform a robust test of the deterrence versus labeling question. We leverage a powerful research design in which twins can serve as the counterfactual for their co-twin, thereby ruling out many sources of confounding that have likely impacted prior studies. The pattern of findings provides support for labeling theory, showing that contact with the justice system—through spending a night in jail/prison, being issued an anti-social behaviour order (ASBO), or having an official record—promotes delinquency. We conclude by discussing the impact these findings may have on criminologists’ and practitioners’ perspective on the role of the juvenile justice system in society.

Why Develop and Support Women's Organizations in Providing Legal Aid in China? Women's rights,women's organizations and legal aid in China

This article argues that women's organizations are central to legal aid for women in China. Chinese women would benefit if more women's legal aid organizations were developed and supported. There are currently too few such organizations, especially in rural areas. Their work challenges the public legal aid programme to develop a rights-based legal aid agenda to achieve greater gender equality through the protection of women's rights. They bring diverse women's perspectives which counter prevailing traditional patriarchal attitudes and male dominance in Chinese society. The emergence of autonomous women's organizations is also important because it helped to break the monopoly of the All China Women's Federation over women's perspectives, identities and interests in China. The article concludes that the competitive yet collaborative relationship between autonomous women's legal aid organizations and the All China Women's Federation is producing a definite and positive impact on gender equality through legal reform.     

After Dark and Out in the Cold: Part-time Law Students and the Myth of 'Equivalency'

This paper presents the findings of the first major research study of part-time law students. It argues that many face multiple disadvantages, largely unrecognized by universities, whose emphasis on the formal equivalency of part-time and full-time law degrees ignores the distinctive backgrounds and needs of part-time students. As a result, many are marginalized, impacting on their retention, overall performance, and work prospects. It is also argued that the context within which part-time law students experience legal education contributes to a collective habitus which may structure what is 'thinkable' for their futures. Such concerns are of particular importance given the strong vocational drive amongst part-time law students. An effective response requires action by both universities and the legal profession. Without this, part-time legal education will remain a fundamentally paradoxical experience, offering broader access to legal practice for non-traditional entrants, while continuing to inhibit their chances of success by entrenching their difference in the eyes of the profession.     

Post-mortem changes of the middle ear: multislice computed tomography study

Six dry skulls were studied by multislice computed tomography (MSCT). They had not previously been prepared, and were natural skeletonized remains. All had been found in the soil. Examination focused on the temporal bones and the ear structures. In all cases, either disruption of the ossicular chain or absence of some ossicular bones were noted. The authors concluded that the fragile ossicles were disrupted in the post-mortem state, and were not indicative of ante-mortem pathology. These observations illustrate the ability of MSCT to visualize taphonomic changes. To further illustrate these findings, we present the results of MSCT performed on an exhumed body. The left ossicular bones were missing and the right ossicular chain was disrupted. With the development of forensic radiology, structures as tiny as the ossicles can be examined. However, the radiologist who performs post-mortem imaging must be familiar with taphonomic changes to avoid interpretation as ante-mortem or peri-mortem traumatic injuries. This could potentially have considerable judicial impact, especially in the study of exhumed bodies.     

Reversal sign on ante- and postmortem brain imaging in a newborn: report of one case

A 16-day-old female newborn was admitted to the emergency department after cardiopulmonary arrest. Total-body radiographs and non-enhanced CT of the brain showed fracture of the right clavicle, pericerebral hemorrhage and brain damage with reversal sign. The infant died on the day of her hospital admission. Because child abuse was suspected, a medicolegal autopsy was ordered by the legal authorities. Prior to autopsy, total-body MRI and CT were performed. Results of the ante- and postmortem investigations were compared with each other and then with the autopsy findings. Postmortem brain imaging showed persistence of the reversal sign. To the best of our knowledge, this is the first case describing hypoxic ischemic damage of the brain parenchyma on antemortem CT and persisting on postmortem imaging in a child abuse case.     

4F‐MDMB‐BINACA: A New Synthetic Cannabinoid Widely Implicated in Forensic Casework

This is the first report regarding the characterization of the new synthetic cannabinoid 4F‐MDMB‐BINACA. 4F‐MDMB‐BINACA was first analytically confirmed in seized drug material using gas chromatography–mass spectrometry (GC‐MS), liquid chromatography–quadrupole time‐of‐flight mass spectrometry (LC‐QTOF), and nuclear magnetic resonance (NMR) spectroscopy. Subsequent to this characterization, 4F‐MDMB‐BINACA was detected in biological specimens collected as part of forensically relevant casework, including medicolegal death investigations and drug impaired driving investigations, from a variety of regions in the United States. Further analysis of biological specimens resulted in the identification of the metabolites 4F‐MDMB‐BINACA 3,3‐dimethylbutanoic acid and 4‐OH‐MDMB‐BINACA. 4F‐MDMB‐BINACA is appearing with increasing frequency as a contributory factor in deaths, creating morbidity and mortality risks for drug users. Laboratories must be aware of its presence and impact, incorporating 4F‐MDMB‐BINACA into workflows for detection and confirmation.
