Elemental analysis of human cremains using ICP-OES to classify legitimate and contaminated cremains

The Tri-State Crematory Incident in Nobel, GA (February 2001) revealed limitations in traditional human cremated remains (cremains) analytical methodology. The goal of this study was to develop a method for effectively classifying questionable sets of cremains as legitimate or contaminated. Eighty-eight samples of known human cremains, concrete, mixtures of the two, and questionable sets of cremains were acid digested and analyzed for 21 elements by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Variable cluster and principle component analyses identified the seven elements (Sb, B, Li, Mn, Sr, Tl, and V) used to develop discriminant functions to classify questionable sets into two groups: cremains and concrete. The discriminant analysis shows that at the 0.90 probability level, mixtures of 50% or less human content were classified as concrete. Mixtures with 90% human content classified as cremains. Sixty percent and 75% human content mixtures remained in the questionable classification, but as the concentration of human increased in the mixture, the probability of assignment to the known cremains group increased. Most of the questionable human samples classified as cremains. This is a pilot study and cannot yet satisfy Daubert standards for courtroom admissibility, but it indicates that it is possible to determine the legitimacy of cremains using elemental analysis by ICP-OES coupled with multivariate statistical analysis.     

Risks and Opportunities of Faith and Culture: The Case of Abused Jewish Women

Intimate partner abusers often focus on physical violence, but abuse may also include exploiting a partner’s faith or subculture. Alternatively, faith or subculture may be a source of strength and support for victims. We explored this by analyzing case files from a Jewish domestic violence services agency. Jewish identity conditions women’s experiences with intimate partner abuse through the use of Judaism as a “tool” for abuse, the role of Jewish holidays and observances, and the role of the Jewish community. While partners of abused Jewish women often perverted the laws and traditions of Judaism to control their partners and the reaction of the larger community varied, being part of an integrated cultural and religious community offered support for some women.     

Ideas, innovations, and networks: a new policy model based on the evolution of knowledge

In this paper, we argue that a new policy model for science and technology is needed and must be evolutionary in nature. The paper proposes utilizing the idea innovation network theory as a framework for assessing sectoral innovation patterns and identifies six types, or “arenas,” of research that are linked to innovation within these networks. Following the idea innovation network theory, the paper argues that two societal trends, the fragmentation of markets and the growth of knowledge, are driving organizations toward greater functional differentiation. Successful innovation will occur when these differentiated organizations become closely linked within innovation networks that integrate the arenas of research. The paper argues that this framework has predictive power, in that it allows the identification of path-dependent blockages or gaps within idea innovation chains that prevent the emergence of effective innovation networks in different countries. Policy makers can play an important role by fostering the development of tightly coupled networks that include organizations involved in each of the types of research. The paper provides empirical support for the framework using a cross-national European study of the telecommunications and pharmaceutical industries.     

Policing Australia’s ‘heroin drought’: using an agent-based model to simulate alternative outcomes

Our paper examines how street-level drug markets adapt to a macro-level disruption to the supply of heroin, under three experimental conditions of street-level drug law enforcement: random patrol, hot-spot policing and problem-orientated policing. We utilize an agent-based model to explore the relative impact of abstractions of these three law enforcement strategies after simulating an ‘external shock’ to the supply of heroin to the street-level drug market. We use 3 years of data, which include the period of the ‘heroin drought’ in Melbourne (Australia) that commenced in late 2000 and early 2001, to measure changes in a selected range of crime and harm indicators under the three policing conditions. Our results show that macro-level disruptions to drug supply have a limited impact on street-level market dynamics when there is a ready replacement drug. By contrast, street-level police interventions are shown to vary in their capacity to alter drug market dynamics. Importantly, our laboratory abstraction of problem-orientated policing is shown to be the optimal strategy to disrupt street-level injecting-drug markets, reduce crimes and minimize harm, regardless of the type of drug being supplied to the market.

Stab injuries of the skull and brain

A few cases of skull and brain stab wounds are described and the clinicodiagnostic problems discussed. The injuries often remain unrecognized because the external wound often appears harmless, there are no neurological symptoms, or the clinical picture is interpreted as drunkenness, blunt injury or as another disease. The importance of a precise physical examination of the whole patient's head is pointed out. The refined methods used in modern radiodiagnostics of the skull are the most helpful in correctly recognizing these injuries; there are reports of patients with severe injuries who recovered when the correct diagnosis had been established.
