Accurate age estimation has always been a problem for forensic scientists, and apposition of secondary dentine is often used as an indicator of age. Cameriere et al. studied the pulp/tooth area ratio by peri-apical X-ray images of the canines, to observe the apposition of secondary dentine. The present study examines the application of this technique in a Mexican identified sample coming from the Department of Physical Anthropology of the INAH, at Mexico City. The main aim of this work is to test the reliability of this method in a skeletal sample of a specific population, different from the samples used for its development. The obtained regression model explained 96.2% of total variance (R(2) = 0.962) with a standard error of estimate of 1.909 and a standard deviation of 1.947. These results demonstrate great reliability and that the age/secondary dentine relationship is not variable in this specific population. 相似文献

This article discusses a number of questions regarding the setting up of ballistic fingerprinting databases, consisting of ammunition components fired by all the firearms held in legal possession. These questions can be classified into three categories--the efficiency of the database, forensic issues, and practical issues to be dealt with. The current New York State legislation is used as an illustration of the choices to be made when setting up a ballistic fingerprinting database. Three important arguments are formulated against the installation of a ballistic fingerprinting database. 相似文献

We model two aspects of executives in parliamentary democracies: Decision‐making authority is assigned to individuals, and private information is aggregated through communication. When information is relevant to all policies and communication is private, all decisions should be centralized to a single politician. A government that holds cabinet meetings, where information is made available to all decision makers, outperforms one where communication is private: A multimember cabinet can be optimal; it need not be single peaked around the most moderate politician or ideologically connected. Centralization is nonmonotonic in the degree of ideological divergence. In a large cabinet, all power should be given to the most moderate politician. Even when uncertainty is policy specific and a single politician is informed on each policy, power should never be fully decentralized. Our model provides a justification for centralized authority and cabinet meetings that enhance the quality of policy. 相似文献

This article analyses three prominent proposals for the functional and political transformation of the EU from a constitutional perspective. It argues that existing EU reform proposals, to varying degrees, entrench rather than reverse the challenges to individual and political self‐determination brought about by the EU's response to its Euro crisis. As the article will conclude, challenging ‘authoritarian liberalism' in an EU context may require the development of a constitutional structure for the Union able to contest, rather than set in stone, the EU's existing economic and political goals. 相似文献

The military operation in Libya (2011) is a paradigmatic case regarding the growing interaction of new security challenges: regional instability, transnational organized crime and illegal immigration. The main aim of the paper is to answer the question: Why has Italy employed a specifically military instrument to tackle transnational and non-military threats? Through process tracing the research looks at the political debate over the decision-making process in the case of the Italian military engagement in Libya, emphasizing the role played by the strategic culture, international norms and domestic dynamics. 相似文献

Odontological identification consists of the comparison of antemortem dental information regarding a missing person with postmortem data from an unidentified corpse or human remains. Usually, the comparison concerns morphologic features that the operator chooses among all the visible characteristics because of inter‐individual uniqueness; for this reason, implants can be of enormous assistance. A case concerning the recovery of a burnt oral implant, connected to a bone fragment, among 2780 charred bone fragments, suspected to have belonged to a victim of homicide, is presented to demonstrate that dental implants and their site of bone integration represent a very precious element for personal forensic identification. Because of their morphological invariability in time and because of their morphologic uniqueness, they were used as evidence to associate unidentified human charred remains to a missing person where DNA analysis failed to do so. The case illustrates the fundamental contribution, not yet described in literature, given by the clinical aspects of tooth replacement with dental implants to a forensic discipline. Clinical practitioners should therefore be aware of the great importance of their work and of dental records in a forensic identification scenario. 相似文献
