Contemporary methods of labeling dental prostheses--a review of the literature

Forensic identification (ID) based on an assessment of the dentition is commonplace. However, despite an increase in the oral health of Western populations, there are still many millions of individuals who are edentulous and whom have been treated with completed dentures. In the United Kingdom alone over 300,000 patients are rendered edentulous each year. In order to facilitate the ID of such individuals a number of forensic and governmental organizations have recommended that dentures be labeled. A number of labeling systems exist which can be broadly separated into inclusion systems, marking systems, and novel methods. Each of the commonly described systems are demonstrated with an assessment of their strengths and weaknesses. It is recommended that an inclusion denture marker, preferably metallic, should be used in order to withstand the most common postmortem assaults.     

The barriers to achieving an evidence base for bitemark analysis

Forensic dentistry is the union of two scientific disciplines, both of which are undergoing a renewed scientific rigor. In forensic science the advent of the Daubert ruling has required that judges assess the forensic value of 'expert testimony' ensuring that techniques, methodologies and practices are not only commonly accepted (as was the previous hurdle during the Frye era) but that error rates, assessment of reliability and validation studies are published to support their use. This new degree of judicial scrutiny has been mirrored in the field of dentistry itself, where organisations search and summarise randomised controlled trials in order to recommend best practice and devise clinical care pathways that are firmly grounded in proven scientific research. Despite the obvious drive from both of these professions, forensic dentistry, and in particular the sub-discipline of bitemark analysis, has been remarkably slow to address the obvious deficiencies in the evidence base that underpins this element of forensic science. Reviews of the literature reveal that the vast majority of published works are case reports, and very little primary literature exists. This paper reviews those studies that have assessed aspects of bitemark analysis including the crucial issue of the uniqueness of the human dentition; the application of transparent overlays and the application of statistical probabilities in bitemark conclusions. There are numerous barriers to undertaking high quality research in the field of bitemark analysis, the most important of which is the use of a gold-standard that is acceptable both in terms of diagnostic research but is also forensically relevant. If bitemark analysis is to continue to play a role in the judicial process then there is an urgent need for high quality studies that meet the levels of forensic and scientific scrutiny applied to other disciplines within the criminal justice system. Studies are required to determine not that the human dentition is unique, but how this asserted uniqueness is represented on human skin and other substrates. The error rates associated with the analysis of bitemarks are required on a procedural level as well as an individual practitioner basis and scales and interpretative indices of bitemark severity and forensic significance should be validated and introduced into common use.     

Dental participants in mass disasters--a retrospective study with future implications

Mass casualty incidents continue to require the services of forensic dentists to determine the identity of victims. Across North America and Europe. teams of forensic dentists train, using mock disaster exercises, to prepare for such duties. It is vital that these mock exercises simulate the features of real disaster situations as far as possible. In order to inform those responsible for the design and implementation of mock exercises, a study was undertaken to determine the features of actual disasters that dental personnel had attended. Using a questionnaire, data were solicited from 38 odontologists. The average number of disasters attended by the respondents was eight, with an average casualty number of 94. Aircraft crashes were the most frequent cause of disasters that were attended by the odontologists. The authors conclude that future mock disaster exercises should replicate features of aircraft crashes as closely as possible by using commingled, fragmented, and burned remains. In addition, mock disasters should require the identification of a realistic number of individuals to ensure authenticity and the maximum logistical preparedness of participants.

Les relations de pouvoir façonnent le cours de l'existence du secteur pétrolier depuis la découverte et la commercialisation de l'or noir remontant au 19e siècle. Progressivement, quoique bien rapidement, cette substance devint le moteur de l'évolution économique mondiale toujours en vigueur. Étrangement, plusieurs études actuelles, que l'on rassemble sous la thèse de la malédiction des ressources (resource curse [RC]), semblent pourtant esquiver leur centralité à la compréhension de la paupérisation et des violences vécues chez les populations de certaines régions riches en ressources pétrolières. À travers la problématisation de la littérature analytique portant sur la RC appliquée à la situation chaotique de la région du delta du Niger au Nigéria et sa mise en relation avec les débats appréciatifs des pratiques de RSE (responsabilité sociale des entreprises), cet article démontre l'importance de prendre en compte l'ensemble des dimensions politiques du vécu de la RSE dans une réalité locale, nationale et internationale aux diverses ramifications "s'inter-constituant."     

Community collaboration in development work with young people: perspectives from Zambian communities

Despite its recognised importance, studies of collaboration within specific communities in the Global South are rare. This paper examines the purposes and processes of collaboration between organisations undertaking development work with young people in two communities in Lusaka, Zambia. Interviewees recognised the need for collaboration given the limitations of existing provision and the fragmented organisational context. Existing collaboration was commonly orientated towards information sharing and joint provision rather than broader coordinated planning. Building awareness and understanding across organisations were viewed as key processes in developing collaboration. To enhance collaboration between organisations, it is suggested that inclusive community forums be instigated.

Collaboration communautaire dans le cadre d'activités de développement parmi les jeunes : points de vue de communautés zambiennes

Malgré son importance reconnue, la collaboration au sein de certaines communautés dans l'hémisphère Sud n'a fait l'objet que de rares études. Cet article se penche sur les finalités et les processus de collaboration entre organisations qui entreprennent des activités de développement avec des jeunes dans deux communautés de Lusaka, en Zambie. Les personnes interrogées reconnaissaient la nécessité de collaborer étant donné les limites des services disponibles et le contexte organisationnel fragmenté. La collaboration existante était fréquemment axée sur le partage des informations et la prestation conjointe, plutôt que sur une planification coordonnée plus large. Le développement de la prise de conscience et de la compréhension entre les organisations était considéré comme un processus clé dans le développement de la collaboration. Pour améliorer la collaboration entre organisations, le lancement de forums communautaires est suggéré.

Colaboración comunitaria en el trabajo de desarrollo con jóvenes: perspectivas de comunidades zambianas

A pesar de la reconocida importancia del tema, la colaboración entre comunidades específicas del Sur ha sido poco estudiada. El presente artículo examina los propósitos y los procesos de colaboración que se establecen entre organizaciones que realizan trabajo de desarrollo entre jóvenes en dos comunidades de Lusaka, Zambia. Dadas las limitaciones de la provisión actual y el contexto organizativo fragmentado, las personas entrevistadas reconocieron la necesidad de colaborar entre sí. En general, se constata que la colaboración ya existente se orienta más a compartir información y a la provisión conjunta que a una planeación coordinada más amplia. Construir conciencia y comprensión entre organizaciones constituye un proceso clave para fomentar la colaboración. El artículo sostiene que la colaboración entre organizaciones puede mejorarse a través de la realización de foros comunitarios incluyentes.

Colaboração da comunidade no trabalho de desenvolvimento com jovens: perspectivas de comunidades zambianas

Apesar de sua reconhecida importância, estudos de colaboração dentro de comunidades específicas no Sul Global são raros. Este artigo examina os propósitos e processos de colaboração entre organizações que estão realizando trabalho de desenvolvimento com jovens em duas comunidades de Lusaka, na Zâmbia. Os entrevistados reconheceram a necessidade de colaboração tendo em vista as limitações da provisão atual e o contexto organizacional fragmentado. A colaboração existente era comumente voltada para o compartilhamento de informações e provisão conjunta em vez de um planejamento coordenado mais amplo. Promover a conscientização e a compreensão entre as organizações foi vistos como um processo-chave no desenvolvimento da colaboração. Para ampliar a colaboração entre as organizações, é recomendado que fóruns comunitários inclusivos sejam promovidos.     

Hedley Bull and International Society: Contemporary Reflections on the Korean Peninsula

The year 2010 witnessed an escalation of tensions on the Korean peninsula through two military crises. The rise in tensions can be explained by neorealism as a shifting distribution of power in the region and a small state preserving its national security. The paper argues that neorealism is not sufficient to explain the patterns and routines of crisis escalation and crisis resumption on the Korean peninsula and the North East Asian region. By focusing on the causes of conflicts neorealism fails to identify the consequences of these inter-state tensions for the evolution of an anarchical society of states in the North East Asian region. The paper provides an alternative interpretation of recent inter-Korean crisis escalation and crisis resolution in the East Asian region through the work of Hedley Bull.
