Metric Sex Determination of the Human Coxal Bone on a Virtual Sample using Decision Trees

Decision trees provide an alternative to multivariate discriminant analysis, which is still the most commonly used in anthropometric studies. Our study analyzed the metric characterization of a recent virtual sample of 113 coxal bones using decision trees for sex determination. From 17 osteometric type I landmarks, a dataset was built with five classic distances traditionally reported in the literature and six new distances selected using the two-step ratio method. A ten-fold cross-validation was performed, and a decision tree was established on two subsamples (training and test sets). The decision tree established on the training set included three nodes and its application to the test set correctly classified 92% of individuals. This percentage was similar to the data of the literature. The usefulness of decision trees has been demonstrated in numerous fields. They have been already used in sex determination, body mass prediction, and ancestry estimation. This study shows another use of decision trees enabling simple and accurate sex determination.     

Challenge Funds in International Development: Definitions,Variations and Research Directions

The use of challenge funds to promote economic and social development continues to grow but has been the subject of relatively little research. This article draws on institutional economics (particularly principal‐agent theory) to define challenge funds and review how they differ from other development funding mechanisms, taking into account their purpose, financial terms, interagency relationships, screening processes, selection mechanisms, implementation and risk sharing characteristics. It then draws on web‐based data for 50 challenge funds to analyse variation in some of these characteristics. The paper identifies evaluability as an important influence, including the relative importance attached to promoting the financial performance of grantees relative to the indirect social benefits of their activities. We conclude with suggestions for further research into the design and performance of challenge funds. Copyright © 2015 John Wiley & Sons, Ltd.     

Analysis of Mitochondrial DNA from a Burned,Ninhydrin‐Treated Paper Towel

Contact‐based evidence is likely to have limited quantities of DNA and may yield mixed profiles due to preexisting or contaminating DNA. In a recent arson investigation, a paper towel was collected and used as circumstantial evidence. The paper towel was partially burned and was likely set on fire with flammable liquid. As part of the investigation, the paper towel was treated with ninhydrin to visualize fingerprint evidence. Initial DNA analysis of two swabs was negative for short tandem repeat (STR) markers and revealed a mixture of mitochondrial DNA (mtDNA). Analysis of 13 additional cuttings yielded four more mixed profiles, but also two samples with a common single‐source profile. The single‐source mtDNA profile matched that of the primary suspect in the case. Thus, even if initial mtDNA analysis yields a mixed profile, a sampling strategy involving multiple locations can improve the chance of obtaining valuable single‐source mtDNA profiles from compromised evidence in criminal casework.     

The Effect of Pretrial Detention on Sentencing in Two Federal Districts

While a substantial body of research indicates that legal variables, such as offense severity and criminal history, principally shape sentencing decisions, other studies demonstrate that extralegal factors such as race, gender, and age influence sentencing outcomes, as well. The handful of studies focusing upon the effect of pretrial detention/release on sentencing outcomes indicate that pretrial detention is associated with greater lengths of incarceration. This study—the first to empirically examine the sentencing consequences of pretrial detention in the United States federal courts—employed a sample of 1,723 cases from two district courts (New Jersey and Pennsylvania Eastern). Pretrial detention and, to a lesser degree, revocation of granted pretrial supervision were associated with increased prison sentences; on the other hand, successfully completing a term of pretrial services supervision was associated with shorter sentence length. Implications for the federal criminal justice system are discussed.     

Working Through Work Release: An Analysis of Factors Associated with the Successful Completion of Work Release

In line with reentry and life course research that has shown increases in desistance for individuals connected with employment, work release programming attempts to achieve desistance from crime by linking criminal offenders to the labor market while in the correctional system. Recent research has speculated that the completion of rigorous employment programming may serve as a signal to employers that criminal careers have ceased and the offenders are employable. Therefore, it is important to understand factors associated with successful program completion. This study utilizes a sample of jail-based work release participants to explore factors correlated with program completion. Consistent with prior research, we find that offenders who are older, Caucasian, and employed at time of arrest are more likely to complete the program and that minority participants and those with prior mental health treatment are less likely to complete the program.     

Exploring the formal and informal roles of regulatory intermediaries in transnational multistakeholder regulation

Research on regulation and regulatory processes has traditionally focused on two prominent roles: rulemaking and rule‐taking. Recently, the mediating role of third party actors, regulatory intermediaries, has started to be explored – notably in a dedicated special issue of the ANNALS of the American Academy of Political and Social Science. The present special issue extends this line of research by elaborating the distinction between formal and informal modes of regulatory intermediation, in the specific context of transnational multistakeholder regulation. In this introduction, we identify two key dimensions of intermediation (in)formalism: officialization and formalization. This allows us to develop a typology of intermediation in multistakeholder regulatory processes: formal, interpretive, alternative, and emergent. Leveraging examples from the papers in this special issue, we discuss how these four types of intermediation coexist and evolve over time. Finally, we elaborate on the implications of our typology for regulatory processes and outcomes.     

Superego,special juries and a split law: eighteenth-century adultery trials viewed through Zizek’s lens

Over the course of several books, Zizek develops a psychoanalytical account of the symbiosis between the public law and the individual subject’s own acquiescence. It is of course a non-formalist theory, suggesting that formal law alone does not achieve social order. This article applies an element of the theory empirically to a historical question: to the question of how the behaviour of juries in a particular type of 18th-century adultery trial managed to be both the object of contemporary controversy and an expression of normative values. The social ambivalence signalled by that doubleness opens surprisingly well to Zizek’s theory that the power of law is divided between its own public form and the subjects’ expression of superego. The theory of the split law, the hidden supplement outside the system, clarifies the historically-specific example. However, the historical example also illuminates the theory: it suggests how the space for this supplement also exists within the system, which can incorporate and make use of it.
