Firearm examination: Examiner judgments and computer‐based comparisons

Forensic firearm examination provides the court of law with information about the source of fired cartridge cases. We assessed the validity of source decisions of a computer‐based method and of 73 firearm examiners who compared breechface and firing pin impressions of 48 comparison sets. We also compared the computer‐based method's comparison scores with the examiners' degree‐of‐support judgments and assessed the validity of the latter. The true‐positive rate (sensitivity) and true‐negative rate (specificity) of the computer‐based method (for the comparison of both the breechface and firing pin impressions) were 94.4% and at least 91.7%, respectively. For the examiners, the true‐positive rate was at least 95.3% and the true‐negative rate was at least 86.2%. The validity of the source decisions improved when the evaluations of breechface and firing pin impressions were combined and for the examiners also when the perceived difficulty of the comparison decreased. The examiners were reluctant to provide source decisions for "difficult" comparisons even though their source decisions were mostly correct. The correlation between the computer‐based method's comparison scores and the examiners' degree‐of‐support judgments was low for the same‐source comparisons to negligible for the different‐source comparisons. Combining the outcomes of computer‐based methods with the judgments of examiners could increase the validity of firearm examinations. The examiners' numerical degree‐of‐support judgments for their source decisions were not well‐calibrated and showed clear signs of overconfidence. We suggest studying the merits of performance feedback to calibrate these judgments.     

Factor analysis applied to magnitude estimates of punishment Seriousness: Patterns of individual differences

This research makes use of factor analysis to locate important dimensions of individual differences in perceptions of legal punishments. A sample of 152 recently arrested persons provided magnitude estimates of the seriousness of several types and levels of punishment. A factor analysis of the data showed that the major dimensions of individual differentiation were in responses to (a) lengthy periods of imprisonment; (b) several punishments judged less serious, including short periods in jail or on probation; and (c) fines. Regressions of the factor scores on individual characteristics are reported, and the implications of the analysis for deterrence theory are discussed.     

Population frequencies of carbonic anhydrase II (CA II), esterase D (EsD), and glyoxalase I (GLO) in the Metropolitan Birmingham, Alabama area

Both black and white populations from Birmingham, Alabama were analyzed for the frequencies of carbonic anhydrase II (CA II), glyoxalase I (GLO) and esterase D (EsD) isoenzymes. The results compared favorably with published frequencies of these genetic markers in other populations.     

The scope and limits of financial liberalisation in developing countries: A critical survey

This article reviews the growing literature on financial reform in developing countries. We draw both on the theoretical contributions outlining the case for and against liberalisation as well as on the experience of many developing countries with liberalisation. We argue that the existence of market failures in financial markets hampers the liberalisation process and indeed suggests that the simple liberalising strategy envisaged in much of the literature is inappropriate. We argue instead for an alternative strategy which integrates some aspects of liberalisation with the development of appropriate financial institutions designed to serve best the needs of the real economy.     

Growing up as an abandoned child in nineteenth-century Italy

In the debate over “maternal indifference” and, more generally, over the ways in which children were viewed and treated in the European past, the care of abandoned children has attracted a good deal of attention. Huge numbers of newborns were consigned to foundling homes in past centuries, and attempts to keep the children alive depended heavily on placing them with rural wetnurses and foster families. In general, scholars have portrayed these foster families as having little concern for the welfare of their charges. One consequence of this view is the presumed instability of foster home arrangements for foundlings. Using archival sources, this article investigates the relationships between foster families and foundlings by examining the lives of babies abandoned at the foundling home in Bologna, Italy over the course of the nineteenth century. The study provides grounds for questioning the received wisdom on the subject of foundling care in nineteenth-century Italy and beyond.     

Associations between national gambling policies and disordered gambling prevalence rates within Europe

Policymakers and other interested stakeholders currently are seeking information about the comparative effectiveness of different regulatory approaches to minimising gambling-related harm. This study responds to this research gap by exploring associations between gambling policies and disordered gambling prevalence rates. We gathered information about gambling policies for thirty European jurisdictions and past-year prevalence rates for disordered gambling for twelve of these jurisdictions. We present policy trends and prevalence rates and then describe the level of association between policy and prevalence. We observe one statistically significant association between policy and prevalence: rates of sub-clinical (i.e., Level 2) disordered gambling were higher within environments that mandated less strict regulation of advertising for online gambling. Finally, we discuss the implications of our research in the context of the current process regarding the pan-European regulation of gambling. Our findings do not offer evidence for certain assumptions made in the past by the European judiciary.
