Adolescent self-poisoning: a cohort study of subsequent suicide and premature deaths

Previous self-harm has been identified as a risk factor for subsequent suicide by adolescents. The objective of the study was to identify further risk factors for subsequent premature death and suicide in a population of adolescents presenting with self-poisoning. A longitudinal cohort design using data-linkage of consecutive adolescent patients presenting to the Hunter Area Toxicology Service, a regional toxicology service for Newcastle, Australia, with the National Death Index of the Australian Institute of Health and Welfare was used. A total of 441 adolescents aged 10 to 19 years presented with self-poisoning over 5 years from January 1991 to December 1995, with follow-up to March 2001. There were 14 deaths total, eight of which were likely suicides. There was a 22-fold increase in suicide rate for males and a 14-fold increase for females compared with age-normalized population rates. Adjusted hazard ratios (95% CI) forpremature death were male gender 3.77 (1.11-12.78), nonaffective psychotic disorders 16.3 (3.83-69.34) and the mental illnesses of childhood 6.12 (1.68-22.23). There was a similar pattern for suicide: Male gender, nonaffective psychotic disorders, and the mental illnesses of childhood confer greater risk for subsequent suicide or premature death in this population.     

Taphonomic mycota: fungi with forensic potential

Forensic archaeologists and criminal investigators employ many different techniques for the location, recovery, and analysis of clandestine graves. Many of these techniques are based upon the premise that a grave is an anomaly and therefore differs physically, biologically, or chemically from its surroundings. The work reviewed in this communication demonstrates how and why field mycology might provide a further tool towards the investigation of scenes of crime concealed in forest ecosystems. The fruiting structures of certain fungi, the ammonia and the postputrefaction fungi, have been recorded repeatedly in association with decomposed mammalian cadavers in disparate regions of the world. The ecology and physiology of these fungi are reviewed briefly with a view to their potential as a forensic tool. This application of mycology is at an interface with forensic archaeology and forensic taphonomy and may provide a means to detect graves and has the potential to estimate postburial interval.     

Isotope ratio mass spectrometry as a tool for forensic investigation (examples from recent studies).

The versatility of isotope ratio mass spectrometry is demonstrated by reference to diverse case studies. Variations in the natural isotopic composition of non-biological, organic materials are compared as a means by which samples may be associated or discriminated. These techniques may be used to augment or compliment conventional forensic methodologies. delta13C analysis was used to demonstrate that different masking tape had been recovered in two, apparently similar cases, involving the smuggling of money. Visually similar ecstasy tablets were compared by consideration of the delta13C and delta15N composition of MDMA extracted from the tablets. Although only a limited number of tablets were analysed, the isotopic similarity between two different seizures was sufficient to induce a guilty plea from a person suspected of possessing both. A combination of delta2H, delta13C, delta15N and delta18O together with GC-MS analyses were applied to small samples of seized heroin. Although GC-MS analysis indicated differences between the chemical composition of two of the heroin samples, isotopic analysis suggested similarities, which were confirmed by further delta2H, delta13C and delta18O isotopic analysis of the clingfilm in which the samples were wrapped.     

The role of people in information-sharing: perceptions from an analytic unit of a regional fusion center

Information sharing research has largely focused on capturing operational practices related to the exchange of information. A noticeable shortcoming of this developing literature is the lack of scholarly attention focused specifically on analytic personnel. The present study employs semi-structured interviews with 23 personnel that comprise the analytic unit within a regional fusion center located in a large metropolitan area in the United States. Findings indicate that there is significant ambiguity surrounding the organizational and geographic audiences to which intelligence products should be tailored. Moreover, it appears information sharing is sparse and reliant upon personal relationships between analysts and external organizations. Lastly, analysts do not receive feedback pertaining to the content and effectiveness of intelligence products created. These findings may be generalized to other analytical organizations whose primary goal is to gather, analyze and disseminate intelligence. Action steps for policymakers are provided.     

An Empirical Note on Economic Freedom and Income Inequality

I report estimates for a fixed-effects model of country-level Gini coefficients as a function of economic freedom along with relevant control variables. Gini coefficients are drawn from the UNU/WIDER World Income Inequality Database Version 2.0a, while economic freedom is measured by the Fraser Institute's Economic Freedom of the World index. Controls are included for per capita income, political structure, education, demographics, and industrial composition. Over a broad range of freedom, the estimated relation between economic freedom and income inequality is positive, statistically significant, but relatively inelastic.     

Coordinating intermediaries: The prospects and limitations of professional associations in decentralized regulation

A key question in understanding regulation through independent intermediaries is the extent to which intermediary actions are either coordinated, thereby supporting consistency in regulatory application, or uncoordinated, leading to monitoring and enforcement disparities. This paper examines professional associations as one mechanism by which policy action may be coordinated in decentralized arrangements. Professional associations provide means and venues for members to interact, offer training and education that develops shared understanding of policy directives, are collective representation bodies for professional members, and may play an important role in establishing and enforcing collective standards for appropriate behavior. We examine these functions in the decentralized administration of United States organic food certification, focusing on two relevant professional associations – the Accredited Certifiers Association and the International Organic Inspectors Association. Drawing on multiple methods, including interviews and survey data, our findings indicate that professional organic certification associations provide valuable education and training, disseminate information, and facilitate knowledge sharing among administrative entities and with regulatory authorities. We conclude with a discussion of the prospects and limitations of professional associations for third‐party regulation, and how accounting for professional association functions can improve our understanding of regulatory intermediary coordination and conduct.     

How Values Shape Program Perceptions: The “Organic Ethos” and Producers’ Assessments of U.S. Organic Policy Impacts

Among the more recognizable programs related to natural and sustainable food is the United States Department of Agriculture’s National Organic Program. Although the robustness of the organic food market is difficult to contest, many debate the extent to which U.S. organic policy outcomes adequately serve consumers and the organic agriculture producers they rely on. This paper engages the debate from the perspective of certified organic producers. Drawing on the results of a nationwide survey of USDA‐certified producers, we first provide a snapshot of how producers assess the environmental, consumer, and market impacts of U.S. organic food policy. We then examine the extent to which organic producers’ policy impact perceptions are associated with their alignment with an “organic ethos”—understood as producers’ commitment to core organic principles and the organic movement. The paper highlights producers’ values as perceptual filters and cognitive mechanisms that help shape producers’ policy impacts perceptions, illustrating a contributing factor to the enduring nature of organic policy debates.     

Examining the constitutionality of Internet filtering in public schools: a US perspective

The use of Internet filters in public classrooms in the USA has been intensely debated, both in terms of its effectiveness and legality. The debate pits concerns to protect students from indecent material against issues of unconstitutional censorship. This paper examines the legal issues addressed in various rulings by the US Supreme Court pertinent to issues raised in the debate over the constitutionality of filtering in the classroom. The rulings and opinions offer valuable insights into the legal issues raised in this debate.     

Violent victimization and involvement in delinquency: Examining predictions from general strain theory

In a recent critique and elaboration of general strain theory, Agnew (2001) argued that criminal victimization might be among the most consequential strains experienced by adolescents, and therefore might be an important cause of delinquency. Few studies to date, however, had examined victimization as a potential cause—rather than outcome—of delinquency. This article addresses this void by examining predictions from general strain theory about the effects of victimization on later involvement in delinquency. The analyses indicated that violent victimization significantly predicted later involvement in delinquency, even when controlling for the individual's earlier involvement in delinquency. Moreover, general strain theory appears to be a useful theoretical framework for examining this relationship. The effects of victimization on delinquency were explained in part by its effects on anger (the key intervening variable specified by the theory). Partial support also emerged for the theory's hypothesis that the effects of strain should be conditional upon other factors. Specifically, the effects of victimization were marginally greater for juveniles with weak emotional attachment to their parents and significantly greater for those low in self-control.
