ABSTRACT: When analyzing human adult skeletal remains, it is often difficult to decide whether a single aging method will give a more reliable age estimation than a combination of methods. This study evaluates four macroscopic indicators for age estimation on 218 American White and Black individuals, ranging in age from 25 to 90 years of age, from the Terry collection. Individuals in the sample were selected to have a balanced race, sex, and age distribution. The following aging methods were applied to each skeleton by one experienced observer: the Suchey–Brooks (SB) pubic symphysis method, the Lovejoy auricular surface method, the monoradicular teeth Lamendin (LM) method, and the I?can (IC) method for fourth ribs. The statistical study involved the evaluation of inaccuracy and bias (based on median age) for each age indicator and the combination of methods using Principal component analysis (PCA). Analysis was performed on the entire sample, then by race, then sex, and then age group (25–40 years, 41–60 years, and >60 years). PCA was the most accurate method for both racial groups when all age groups are analyzed together. When the sample was divided into age groups, SB was the most accurate for young adults (25–40 years) and LM was the most accurate for middle adults (41–60 years). After the age of 60, all methods are highly inaccurate, although IC gives the lowest inaccuracy. As regards bias, the study highlights the tendency of all methods to overestimate the age of young individuals and to underestimate in the older age group. No single skeletal indicator of age at death is ever likely to reflect accurately the many factors that accumulate with chronological age. In fact, one must use as many dental and skeletal indicators as possible. However, in order to maximize the potential of each method, in the final evaluation one should consider mainly the method or methods that have a higher accuracy for a particular age range. 相似文献

Sommaire: L'État incite les établissements publics et les organismes communautaires à développer et à augmenter la fréquence de leurs relations interorganisationnelles. L'État veut ainsi favoriser une intégration des services permettant une meilleure réponse aux besoins sociaux de la population. Cette étude propose une typologie permettant d'analyser les modèles de relation qui se mettent en place entre ces deux groupes d'acteurs. La recherche s'est intéressée aux interfaces dans le secteur des services sociaux à l'enfance, à la jeunesse et aux familles québécoises. Au total, 111 gestionnaires ont répondu à un questionnaire leur permettant d'évaluer leurs rapports en fonction de quatre dimensions proposées par Coston pour situer les relations entre l'État et les organismes du tiers secteur. Le modèle de relation rapporté par les répondants est celui de la coexistence. Quoique le modèle de relation rapporté par les organismes communautaires et par les établissements publics soit le même, une analyse plus nuancée des résultats permet de constater que les organismes communautaires se perçoivent appartenir à un système plus socio‐étatique (dominé par les établissements de réseau) que les répondants des établissements publics. Abstract: The government encourages public institutions and community organizations to develop and increase the frequency of their inter‐organizational relationships. In doing so, the government seeks the integration of their services in order to meet the social needs of the population more effectively. This study aims to develop a typology for analysing patterns in the relationships being established between these two groups of stakeholders. The research focused on the interfaces in the social service sector for children, youth and families in Quebec. In total, 111 managers responded to a survey that enabled them to assess their relationships on the basis of four dimensions proposed by Coston for analysing relationships between the government and third‐sector organizations. The respondents identified “coexistence” as the most common type of relationships. Although the community organizations and the public institutions identified the same type of relationships, a more nuanced analysis of the survey results reveals that community organizations see themselves as part of a system that is more “socio‐governmental” in nature (i.e., dominated by the institutions in the network) rather than “public.” 相似文献

This paper presents the results of a public survey on the perceived severity of different kinds and levels of penalties gathered using magnitude estimation techniques. Three topics are dealt with. Individual scales of sentence severity are shown to be internally consistent. Then the structural properties of the severity scales of fine, imprisonment, community work, and probation are analyzed. Finally, what a given penalty is worth in relation to other types of punishment from the public's point of view is established and compared to existing exchange rates prescribed in legal statutues or practiced by criminal courts. 相似文献

Abstract: Lamendin and colleagues (1992) proposed to assess age‐at‐death from root translucency and periodontosis. Several teeth from the same individual were included in their study. In our work, we evaluate the reliability of their formulas without introducing this bias. Our sample was constituted of 214 individuals (114 males and 100 women) selected from the Terry collection (U.S.A.). The R2 between age and both indicators is equal to 0.33 and 0.08 (p < 0.001). Based on linear regression, the mean of standard error for individual age prediction was equal to 13.67 years, and the mean interval length is equal to 53.89 years. Multinomial logistic regression and Bayesian approach failed to give satisfactory results when classifying the individuals in age categories. Therefore, the use of root translucency and periodontosis may lead to incorrect age‐at‐death assessment, and it is thus necessary to complement this approach with other techniques to assess age‐at‐death. 相似文献

The use of applications on mobile devices is gradually becoming a new norm in everyday life, and crime scene investigation is unlikely to escape this reality. The article assesses the current state of research and practices by means of literature reviews, semistructured interviews, and a survey conducted among crime scene investigators from Canada and Switzerland. Attempts at finding a particular strategy to guide the development, usage, and evaluation of applications that can assist crime scene investigation prove to be rather challenging. Therefore, the article proposes a typology for these applications, as well as criteria for evaluating their relevance, reliability, and answer to operational requirements. The study of five applications illustrates the evaluation process. Far away from the revolution announced by some stakeholders, it is required to pursue scientific and pragmatic research to set the theoretical foundations that will allow a significant contribution of applications to crime scene investigation. 相似文献

This article examines the present discourse of conflict resolution and offers an alternative framework for analyzing the generic sources of conflict at the community, state, and interstate levels. In particular, we argue that although peace is a universal value, there are no universally best strategies to achieve it. This, however, does not mean that the path to peace is fundamentally different in every context. We claim that stable democratic political structures in general lead to peace both in the international and the domestic realms. As such, democratization does lead to peace, but the paths to stable democracy are context sensitive. Therefore, the success of efforts aimed at creating long-term peace, both among and within nations, depends on the extent to which, democratization incorporates the norms and values of the societies in question. The article begins with a brief overview of some of the problems associated with defining peace. We suggest that peace should be looked at as a universal value, as democracy has been in the recent past. We provide a more detailed theoretical assessment of the linkage between democracy and peace. Our general argument is illustrated in the South Asian, specifically the Indian, context. 相似文献
