Teeth and bones are frequently the only sources of DNA available for identification of degraded or fragmented human remains. The unique composition of teeth and their location in the jawbone provide additional protection to DNA compared to bones making them a preferred source of DNA in many cases. Despite this, post-mortem changes in the structure and composition of teeth, and the location and diagenesis of DNA within them are poorly understood. This review summarises current knowledge of tooth morphology with respect to DNA content and preservation, and discusses the way in which post-mortem changes will affect the recovery of DNA from teeth under a range of commonly used extraction protocols. We highlight the benefits and pitfalls of using specific tooth tissues for DNA extraction and make recommendations for tooth selection and sampling that will maximise DNA typing success. A comprehensive understanding of tooth structure and an appreciation of the relationship between DNA and mineralized tissues in post-mortem teeth are critical for optimal sample selection. More informed sampling methods that target specific tooth tissues will increase the likelihood of successful genetic analysis and allow for efficient and timely missing persons case work and disaster victim identification response. 相似文献

In the Cambridge Study in Delinquent Development, over 400 London males have been followed up from age 8 to age 48 in face-to-face interviews and up to age 56 in criminal records. About 42 % of the males were convicted up to age 56. During five age ranges up to age 47, 94 % of the males admitted at least one of eight offenses, in comparison with 31 % who were convicted for at least one of these offenses in these age ranges. The prevalence of offending, and the number of offenses committed, decreased steadily after age 18 according to both convictions and self-reports. On average, there were 38 self-reported offenses per conviction, and this ratio also decreased with age. Convicted males self-reported 25 offenses per conviction on average. It is concluded that the “scaling-up factor” from convictions to self-reported offenses is very important, especially in evaluating the effectiveness of intervention programs. 相似文献

A range of seemingly rival theories attempt to explain why some individuals take extraordinary risks by choosing to participate in armed conflict. To date, however, competing accounts have typically not been grounded in systematic, empirical studies of the determinants of participation. In this article, we begin to fill this gap through an examination of the determinants of participation in insurgent and counterinsurgent factions in Sierra Leone's civil war. We find some support for all of the competing theories, suggesting that the rivalry between them is artificial and that theoretical work has insufficiently explored the interaction of various recruitment strategies. At the same time, the empirical results challenge standard interpretations of grievance-based accounts of participation, as poverty, a lack of access to education, and political alienation predict participation in both rebellion and counterrebellion. Factors that are traditionally seen as indicators of grievance or frustration may instead proxy a for more general susceptibility to engage in violent action or a greater vulnerability to political manipulation by elites. 相似文献

After months of bombing, NATO achieved only a stalemate in Libya. That disappointing result may reflect NATO's commitment to respect “international humanitarian law,” now understood to impose severe limits on military operations that might harm civilians. This body of rules is a departure from traditional understandings of the law of war. The embrace of these inhibiting rules raises serious questions about whether western nations are now prepared to fight and win actual wars. 相似文献

With continual advances in Internet capability the child pornography market is experiencing a boom in demand and supply. Attempts to reduce the market challenge legislators, law enforcement agencies, practitioners and researchers alike – due in large part to the decentralised and global nature of the Internet. Much research has focused on frequent users of child pornography and whether such behaviour is interrelated with child sexual assaults. This article instead draws attention to onset, the first deliberate viewing of child pornography. It presents the results of a three-month study of a global Peer-to-Peer network, isoHunt. Analysis of the site’s Top 300 search terms indicated that child pornography is consistently shared. Risk factors for onset are discussed, including the potential normalisation of child pornography among Internet subcultures. Strategies are discussed to encourage subcultures to inhibit child pornography use and to increase understanding of the harms associated with such material. Implications for legal systems, policy and research are explored. 相似文献

Conventional accounts of the Federal Convention of 1787 point to the many different compromises made at the convention, specifically the Great Compromise on representation and the Three‐Fifths Compromise on slavery. Often these compromises are treated as separate events, the result of deliberation leading to moderation of delegate positions (presumably among the key states of Massachusetts and North Carolina). However, by applying the techniques of roll‐call analysis, we find this traditional account is at best incomplete and probably misleading. While the Massachusetts delegation's behavior seems consistent with a moderation hypothesis, we find evidence that the other crucial vote for the Great Compromise—from North Carolina—is inconsistent with moderation, but can be linked through the agenda to the Three‐Fifths Compromise over slavery, taxation, and representation. We conclude by arguing that this reconsideration of some of the convention's key votes should cause political scientists and historians to reevaluate how they see the compromises at the convention. 相似文献

Carl J. Friedrich’s concept of administrative responsibility is examined in his published works from 1935 to 1960. Friedrich’s idea of responsibility encompassed not only political and personal responsibility within the hierarchy of bureaucratic organizations, but also functional responsibility based on scientific knowledge and professional standards required by the reality of administrative discretion. Friedrich’s notion of responsibility is contrasted with that of Herman Finer, who espoused strict obedience to political and administrative superiors. An examination of the NOMOS series of edited volumes from the later stage of Friedrich’s career reflects the consistency of his views on responsibility and on the relationship of responsibility to authority based on reasoned communication. Friedrich’s optimism regarding such authority contrasts with Hannah Arendt’s view that authority is no longer an operative concept in modern society. Friedrich lays an important foundation for continued interest among public administrative scholars in the concept of administrative responsibility. 相似文献

The following study is an evaluation of the Moderate Intensity Family Violence Prevention Program (MIFVPP). The sample consisted of 298 male federal offenders who participated in the MIFVPP while incarcerated or on release within the community. Participants were assessed pre-, mid-, and postprogram using an assessment battery consisting of self-report questionnaires and facilitator-rated evaluation scales. Results of the study found uniform and significant (p < .001) improvement for pre and post program change in the self-report questionnaires and in the facilitator ratings. A positive improvement in motivation, whether assessed by the participant or facilitator, was associated with improvement in program outcomes and significant within, between, and interaction effects were found when participant program performance over time was compared among grouped postprogram ratings of motivation. The implication for the efficacy of addressing offender motivation to change in intimate partner violence (IPV) interventions is discussed. 相似文献
