A meta-analytic review of the frequency and patterning of laryngohyoid and cervical fractures in cases of suicide by hanging

The frequency and distribution of fractures are commonly utilized to assist in interpreting the manner of death. In cases of alleged suicide by hanging, however, the evidence base for the frequency and patterning of laryngohyoid and cervical vertebrae fractures resulting from such blunt force traumatic events is limited and so fractures cannot be reliably used to assist in interpreting the manner. Using meta-analytic techniques, this study aimed to estimate frequency and distribution of fractures in the context of relevant intrinsic and extrinsic variables. A systematic review of the literature identified 20 studies with relevant data (8523 cases of suicide by hanging). Meta-analyses identified the frequency and distribution of fractures present and how fracture frequency was affected by the subgroups of age, sex, completeness of suspension, ligature knot position and study design. Results indicated that fracture frequency was variable, there was no unique patterning, and high levels of heterogeneity were present in all variable sub-groups. Age was the only subgroup to show differences. Findings suggest that neck fracture frequency is inconsistent and cannot be predicted by the chosen variables. Subsequently, neck fractures in isolation should not be given weight in medico-legal interpretations of a hanging death as suicidal.     

Validation of the InnoXtract™ DNA extraction method for bone,teeth, and rootless hair

Forensic casework samples often include human hairs, teeth, and bones. Hairs with roots are routinely processed for DNA analysis, while rootless hairs are either not tested or processed using mitochondrial DNA. Bones and teeth are submitted for human remains identifications for missing persons and mass disaster cases. DNA extraction from these low templates and degraded samples is challenging. The new InnoXtract DNA extraction method utilizes magnetic beads that are optimized to bind small DNA fragments, as small as 100 base pairs, to purify high-yield DNA from compromised samples. This validation study evaluates InnoXtract's ability to obtain amplifiable DNA from samples such as rootless hairs and skeletal remains. Studies performed include sensitivity, stability, repeatability, reproducibility, non-probative samples, and comparison to standard organic extractions. Sensitivity studies demonstrate average yield recoveries ranging from 53% to 100% and 73% to 85% for the InnoXtract hair and bone methods, respectively. Studies demonstrate consistent results across a range of sample types, such as insulted and un-insulted bone and teeth, as well as hair shafts from donors of various ages, gender, race, and hair characteristics. The InnoXtract bone method outperformed organic extraction. The method was successfully automated on a MagMAX™ Express-96, with recoveries over 70% relative to the manual version. InnoXtract has the potential as an automated high-throughput, high-yield bone extraction method with 6 h of total extraction time for up to 96 samples. The validation study results demonstrate that the InnoXtract kits produce high-yield and high-quality DNA from compromised bone, teeth, and hair shaft samples.     

Terror and Its Limits: The Historical Understanding of Terrorist Movements,States and Tribes in an Age of Cultural Anxiety

This article argues that much of the historical analysis of terror and terrorism in history has been weak in understanding the limits on terrorist activity and how terrorist campaigns eventually end. Reviewing three recent studies that examine various aspects of terrorism and the language of terror, the article seeks to show that states often play a major role in the way terrorist movements develop and eventually end up either defeated or moving into mainstream political engagement. The article points to a number of examples to illuminate this including the Carbonara in nineteenth century Italy, the Paris Commune and the ending segregation in the U.S. South in the 1960s.     

Post-liberation Politics in Africa: examining the political legacy of struggle

This article examines the politics of African states in which insurgencies or liberation movements have taken control of the government. It analyses the impact on governance of reforms introduced by these post-liberation regimes, their relations with traditional authorities and civil society and relationships within and between competing guerrilla movements. It interrogates the nature of the state that emerges from this process. The ‘post-liberation’ state label is argued to be both meaningful and useful, as part of a larger project of exploring and explaining the post-colonial African state, highlighting debates about representation, citizenship and nation building. While post-liberation regimes have advantages in implementing state building projects, they are also subject to contestation when the new state institutions and regime incumbents become too exclusivist or predatory.     

Constitutional law

Recent decisions of New Zealand courts illustrate that domestic proceedings may not be effective to recognise indigenous property rights, nor to address grievances that stem from breaches of customary indigenous rights. One possibility for Māori to have their rights enforced is to consider using international law. Gains have been made in international law with regard to indigenous rights; one noteworthy decision is Mayagna (sumo) Awas-Tingni Community v The Republic of Nicaragua. In this case, a universal and generic property right was extended consistently with emerging indigenous rights to include an indigenous right to customary land tenure. This paper considers whether the International Covenant on Civil and Political Rights can carry a property right for indigenous peoples in New Zealand.

Addressing the mental healthcare needs of foster children: perspectives of stakeholders from the child welfare system

A qualitative study was conducted to better understand the factors that contribute to psychotropic medication (PM) overuse among children in the child welfare system in Kentucky, including barriers to providing psychosocial interventions that potentially minimize the need for PM. Semi-structured interviews were conducted with personnel in the Department of Community-Based Services (DCBS). Participants identified important areas to target for system-wide quality improvement efforts, which included improved exchange of health information, training, and communications on the use of PM, and measures to improve access to non-pharmacological psychosocial interventions to address the mental healthcare needs of children in the child welfare system.
