Analysis of histomorphometric variables: Proposal and validation of osteon definitions

Histological analysis of bone tissue has been used to explore a variety of questions relating to age-at-death, habitual behaviors, health, and nutritional stress. Identification of intact and fragmentary osteons is of key interest to many researchers in these studies, yet the definitions of these features vary between researchers making cross-study comparisons problematic. Furthermore, histological variable definitions are often ambiguous or require subjective classifications by the observer. As a result, and as indicated by previous studies, observer error and misclassification of certain variables, namely intact and fragmentary osteons, can be significant. This study proposes new definitions for intact and fragmentary osteons that are designed to limit observer subjectivity and also explore efficacy of combining osteon types into one variable. A sample of 30 6th rib cross-sections from a modern forensic population was used to test the validity of the proposed definitions. Observations of intact osteon population density (OPD(I)) and fragmentary osteon population density (OPD(F)) were made by three observers for each cross-section. These observations were used to explore the interobserver error associated with the proposed definitions and determine if combining variables into one variable (OPD) mitigates persisting classification difficulties. Results indicate that the proposed definitions significantly reduce interobserver error and misclassification of intact and fragmentary osteons. However, the interobserver error associated with fragmentary osteons is still high. Evaluation of the variables independently indicates that combining variables has potential to reduce the predictive strength of an age estimation model and the ability to interpret age-related bone remodeling.     

Self‐Strangulation Through A Sphygmomanometer: An Uncommon Suicide

Suicide by asphyxia is quite a common event in forensic practice and may be implemented in different ways. The authors report a unique case of a 16‐year‐old youth who committed suicide by means of a standard mercury sphygmomanometer. This manner of suicide has never been described in the literature reviewed. A complete forensic investigation led to the conclusion that the cause of death was mechanical asphyxia, ascribed to self‐strangulation by means of an atypical item. The victim suffered from attention‐deficit/hyperactivity disorder (ADHD) syndrome and was assisted by support teachers. He had a solitary and depressive personality. The exceptional nature of this case suggests that sphygmomanometers may be regarded as possible means of self‐strangulation. The case also highlights the importance of managing patients with psychiatric or cognitive disorders; indeed, particular caution is required to keep them away from objects that, although apparently harmless, can become lethal.     

Measurement of airborne gunshot particles in a ballistics laboratory by sector field inductively coupled plasma mass spectrometry

The present study aimed determines lead (Pb), antimony (Sb) and barium (Ba) as the major elements present in GSR in the environmental air of the Ballistics Laboratory of the S?o Paulo Criminalistics Institute (I.C.-S.P.), S?o Paulo, SP, Brazil. Micro environmental monitors (mini samplers) were located at selected places. The PM(2.5) fraction of this airborne was collected in, previously weighted filters, and analyzed by sector field inductively coupled plasma mass spectrometer (SF-HR-ICP-MS). The higher values of the airborne lead, antimony and barium, were found at the firing range (lead (Pb): 58.9 μg/m(3); barium (Ba): 6.9 μg/m(3); antimony (Sb): 7.3 μg/m(3)). The mean value of the airborne in this room during 6 monitored days was Pb: 23.1 μg/m(3); Ba: 2.2 μg/m(3); Sb: 1.5 μg/m(3). In the water tank room, the air did not show levels above the limits of concern. In general the airborne lead changed from day to day, but the barium and antimony remained constant. Despite of that, the obtained values suggest that the workers may be exposed to airborne lead concentration that can result in an unhealthy environment and could increase the risk of chronic intoxication.     

PROTECTING YOUTH PLACED IN UNLICENSED,UNREGULATED RESIDENTIAL “TREATMENT” FACILITIES

Throughout the country, there is considerable inconsistency in how states regulate residential treatment programs for youth. In states with little oversight, the health and safety of youth are unprotected and they may be subject to substandard treatment, rights violations, and/or abuse. Three initiatives to address this issue are reported: (1) an Internet survey of youth who are former residents, (2) a four‐state pilot study of how states regulate and monitor residential programs, and (3) a bridge‐building conference between residential treatment providers and mental health leaders. Recommendations address the next steps for lawmakers, lawyers, judges, mental health and education professionals, and parents.

South–South cooperation and the international development battlefield: between the oecd and the UN

This article discusses the transformation in development architecture, focusing on the role of emerging powers and the growing relevance of South–South cooperation (ssc). Drawing on a conceptual toolkit based on the work of Pierre Bourdieu, it aims to approach ssc as a narrative and to understand the processes of contestation that have turned international development into a battlefield since the end of the 1990s. The article argues that the emergence of ssc has contributed to decentring the field of international development, both in terms of the agents authorised to play and the practices considered legitimate. Within this process the Global Partnership for Effective Development Cooperation, led by the oecd’s Development Assistance Committee, and the United Nations Development Cooperation Forum have become two sites on the battlefield on which the borders of international development are being redrawn.     

Innovations in the provision of public goods and services

Current efforts at administrative reform in both developed and developing countries have invariably focused on the critical issue of provision of public goods and services. The accumulated experience and attendant innovations are therefore vast. Few attempts have been made to pull this experience together and draw salient features which might be of use to newcomers to the task of improving provision of public goods and services. This article draws on a panel of experts and government officials convened by the author who have reflected and/or experimented with innovative approaches to public good and service provision. After discussing the role of the state, market and civil society relative to public goods and services, the article lays out a set of basic institutional options for innovations in provision. The article concludes with some strategic considerations on the sequencing of steps to achieve successful market-based innovations in the provision of public goods and services in the context of the minimalist and the strong but restrained state. © 1998 John Wiley & Sons, Ltd.
