One of the tasks of a forensic anthropologist is to sort human bone fragments from other materials, which can be difficult when dealing with highly fragmented and taphonomically modified material. The purpose of this research is to develop a method using handheld X‐ray fluorescence (HHXRF) spectrometry to distinguish human and nonhuman bone/teeth from nonbone materials of similar chemical composition using multivariate statistical analyses. The sample materials were derived primarily from previous studies: human bone and teeth, nonhuman bone, nonbiological materials, nonbone biological materials, and taphonomically modified materials. The testing included two phases, testing both the reliability of the instrument and the accuracy of the technique. The results indicate that osseous and dental tissue can be distinguished from nonbone material of similar chemical composition with a high degree of accuracy (94%). While it was not possible to discriminate rock apatite and synthetic hydroxyapatite from bone/teeth, this technique successfully discriminated ivory and octocoral. 相似文献

Water conservation policy is a natural laboratory for addressing general issues of relevance to policy analysis and public administration, particularly the relative effectiveness of policies in changing human behavior. Using multivariate regression analysis of a dataset comprised of more than 200,000 monthly observations of more than 19,000 household accounts over six years, this paper makes three main contributions. First, it contributes to the substantive area of water conservation policy by analyzing what works. Second, it contributes to our understanding of generic policy instruments. Third, it raises an important issue regarding standard assumptions about selection bias. The results support earlier work warning that offsetting behavior can negate engineering solutions to policy problems, but further indicate that adding communication to engineering solutions can create cooperation that overcomes offsetting behavior. They also provide evidence that appropriate regulation can be effective, and that pricing can be effective even when price elasticities of demand are low. 相似文献

The authors examine the role of international faith‐based NGOs in foreign aid and development assistance for Africa, with special reference to the Mennonite Central Committee (MCC). The MCC is successful in its contribution to development and empowerment in the 20 African countries in which it works because of its philosophical and programmatic focus on accountability, its holistic approach to basic rights, and a ‘listen and learn’ approach which embraces empowerment and social justice. Although a ‘small is beautiful’ philosophy does not necessarily feed the ‘quick fix’ methods associated with the New Policy Agenda, it remains the most effective, efficient, accountable, and grassroots‐responsive way of dealing with development issues. 相似文献

This article explores the role of law in cultural and political disputes concerning dead bodies. It uses three interconnecting legal frameworks: cultural and moral ownership, commemoration, and closure. It begins with a critique of the limitations of the private law notion of 'ownership' in such contexts, setting out a broader notion of cultural and moral ownership as more appropriate for analysing legal disputes between states and indigenous tribes. It then examines how legal discourses concerning freedom of expression, religious and political traditions, and human rights and equality are utilized to regulate the public memory of the dead. Finally, it looks at the relationship between law and notions of closure in contexts where the dead have either died in battle or have been 'disappeared' during a conflict, arguing that law in such contexts goes beyond the traditional retributive focus of investigation and punishment of wrongdoers and instead centres on broader concerns of societal and personal healing. 相似文献

This study examined the protective function of mother-adolescent relationship quality in mediating the association between maternal history of violent victimization and adolescent behavior problems. Participants included a subsample of 191 mother-adolescent dyads from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) who were at highest risk of child maltreatment. Results revealed that 78.5 % of the mothers reported a history of victimization, which was significantly associated with maternal mental health issues and both adolescent internalizing and externalizing behaviors. Bootstrapping analyses revealed that mother-adolescent relationship quality significantly mediated the relationship between maternal history of victimization and adolescent behaviors. 相似文献

This study tests a model of physical aggression in a sample of 194 men being treated for physical or psychological aggression in the greater Madrid area of Spain. The prevalence of aggression in this sample was lower than in a US batterer sample. In the path model highlighted here, borderline personality traits and alcohol problems were identified as risk factors for physical aggression perpetration and the role of borderline traits was mediated by psychological aggression. A reciprocal relationship was found between psychological perpetration and victimization but not physical perpetration and victimization. These findings are discussed within a cross-cultural context; conceptual and treatment implications are also addressed. 相似文献

Adermatoglyphia is a very rare autosomal‐dominant condition that is genetically inherited and causes an individual to be born without conventional ridge detail on either their palmar or plantar surfaces (the fingers and palms of the hands and the toes and the soles of the feet). While adermatoglyphia has been the focus of medical and genetic research, no previous research has been conducted with regard to the forensic recovery and identification of marks from an adermatoglyphic individual. By observation of ridge detail donated by an adermatoglyphic subject, the study uses different methods in order to capture fingermarks (methods include: inked capture, livescan (biometric) capture, cyanoacrylate fuming, ninhydrin enhancement, and physical developer). Unusually, the purpose of this paper ends up presenting a number of examples of an absence of evidence; unsuccessful attempts made to capture and enhance fingerprint ridge detail. This is determined over a range of standard means including "live" donations by the adermatoglyphic subject onto the Livescan system, and enhancements of latent donations. The subject shows to leave either insubstantial fingermarks with no detail, or no mark whatsoever. 相似文献

Issues of sexual and gender diversity (SGD) appear to generate a disproportionate amount of controversy and emotional intensity relative to other issues of moral concern, particularly among Christians. How can people with differing views stay at the table and navigate conversations and decisions about SGD without necessarily dividing or disintegrating families and churches? This article discusses some of the key psychological barriers to constructive dialogue and decisions about SGD among Christians. These barriers include the ways in which people understand and use sex/gender categories to organize their social worlds, variability in tolerance for ambiguity and change, differences in the foundations used to frame moral concerns, and particularly the ways in which emotions function to motivate and reinforce our responses to SGD. Because these psychological aspects function mostly automatically and unconsciously and interact in complex ways, awareness is a necessary first step in moving forward constructively. Specific suggestions for scholarly research as well as strategies for community leaders attempting to engage with SGD are provided. 相似文献
