The discussion of “error” has gained momentum in forensic science in the wake of the Daubert guidelines and has intensified with the National Academy of Sciences' Report. Error has many different meanings, and too often, forensic practitioners themselves as well as the courts misunderstand scientific error and statistical error rates, often confusing them with practitioner error (or mistakes). Here, we present an overview of these concepts as they pertain to forensic science applications, discussing the difference between practitioner error (including mistakes), instrument error, statistical error, and method error. We urge forensic practitioners to ensure that potential sources of error and method limitations are understood and clearly communicated and advocate that the legal community be informed regarding the differences between interobserver errors, uncertainty, variation, and mistakes. 相似文献

Backspatter from wounds caused by contact shots against a biological target had before been shown to be propelled into firearms' barrels where they can persist and be retrieved from as relevant forensic evidence. Herein, that insight was applied to the investigation of a case of multiple familial homicide with a firearm. Samples of backspatter were collected from the firearm using DNA‐free swabs. DNA was extracted from the swabs, and 16 STR systems were PCR‐amplified to generate DNA profiles of all victims shot by the firearm. The quality of the resulting DNA profiles was sufficient to exclude the perpetrator as donor and to differentiate the three closely related victims thereby proving that all three victims had been shot by the same firearm from very close or contact distance. A key insight gained from this case was that not only a firearms' barrel inside but other inner surfaces may be charged with profilable DNA. 相似文献

Purpose
Psychopathy and psychopathic personality traits (PPT) have been linked to a long list of negative life outcomes. To date, however, few studies have provided a systematic analysis of whether psychopathic personality traits contribute to increased health burden. The current study was designed to address this gap in the literature.Method
This study analyzed data from the National Longitudinal Study of Adolescent Health and employed a measure of PPT derived from the five-factor model of personality. Analyses were conducted using OLS, logistic, and Poisson regression techniques.Results
The results revealed that relatively higher scores on psychopathic personality traits were associated with a slight increase in a wide range of negative health outcomes. These significant associations were detected for both males and females.Conclusions
We speak to the importance of these findings for the potential to reduce health burden among psychopaths and those who score relatively high on measures of psychopathic personality traits. 相似文献254.
This article addresses the security challenge posed by laboratory research involving genetic modification of microorganisms that could be applied for both benign and malevolent purposes. The authors propose that, for biological arms control purposes, a global governance culture is required to manage the security risks inherent in such research while minimizing scientific opportunity costs. 相似文献

Lie-detection research has shown that observers who rely on nonverbal cues or on verbal cues correctly classify on average 54% of truth tellers and liars. In addition, over the years, countless numbers of innocent people have made false confessions and, in analysing the problem, researchers have implicated both a suspect's vulnerability and the persuasive influence of certain police interrogation tactics. Levine et al. (2014) aim to contribute to these vast bodies of literature by reporting two studies purportedly showing that expert interviewers – when they are permitted to question interviewees – can achieve almost perfect accuracy without eliciting false confessions. We argue that theoretical and methodological aspects of these studies undermine the reliability and validity of the data reported, that as a result the studies do not contribute to the scientific literatures on lie detection and false confessions in any meaningful way, and that the results are dangerously misleading. 相似文献

A nation's endowment with human capital is an important source of economic prosperity, yet education systems as well as the amount of public spending differ both between and within industrialised countries. Traditional approaches in comparative political economy explain education spending from a perspective in which leftist parties favour human capital formation. In contrast, recent approaches claim that – with regard to public financing of higher education in stratified education systems – the basic assumptions of partisan theory rather lead to the opposite hypothesis. In such systems, a pattern of reverse redistribution emerges, under which electoral incentives let right-wing parties favour increases in higher education budgets. This article tests both claims within the decentralised German education system. Its encompassing empirical strategy provides clear support for the latter hypothesis in the 16 German states between 1992 and 2003. The results imply that the partisan composition of government and preferences for redistribution continue to matter. 相似文献

We report evidence that trust is the missing root relating education, institutions, and economic development. We observe that more trust both increases education and improves legal and bureaucratic institutions, which in turn spurs economic development. We substantiate this intuition with a series of regressions that provide evidence that trust determines both education and the quality of institutions, and that education and institutions in turn affect GDP per capita. 相似文献

This paper (re-)examines the literature on Traveller communities in the United Kingdom by combining parts of Michel Foucault's and Michel de Certeau's theoretical legacies. Following an ethnographic summary, I demonstrate the relevance of Foucault and Certeau for a critical understanding of the Travellers’ structural predicaments and ideological resistance in the twentieth and twenty-first centuries. I argue that Foucault's outline of modern power, surveillance and classification sheds new light on the impact of social control agencies and the implementation of legislative changes, such as the 1968 Caravan Sites Act, on (semi-)nomadic and/or self-employed groups. The implications of more recent legal developments are discussed as symptoms of postmodernity and the further ideological marginalisation of “non-consuming nomads”. I then argue that some of Certeau's key concepts, including the “strategies/tactics” distinction, illuminate the Travellers’ modalities of resistance and symbolisms of difference. Completing a two-way dynamic between theory and data, the article also shows that existing empirical material on Travellers highlights some of the weaknesses in Foucault's and Certeau's respective thought. Finally, I turn to Foucault's “analytics” to account for intra-group power and resistance, and hence to challenge the common portrayal of Foucault as a “theorist of domination” in juxtaposition to Certeau as a “theorist of subversion”. 相似文献
