Ethnic differences in the relationship between psychopathy and (re)offending in a sample of juvenile delinquents

The present study focused on the relationship between psychopathy and delinquency in a multiethnic sample of juvenile offenders (N=207, n=105 native Dutch, and n=102 immigrants) referred to a treatment program. Aims were (1) to examine the cross-ethnic equivalence of the Antisocial Process Screening Device (APSD); (2) to compare the mean levels of psychopathic traits in native Dutch and immigrant juvenile delinquents and (3) the strength of the associations between psychopathic traits and delinquency in both the native Dutch and immigrant samples. Measurement invariance was established for APSD factors assessing callous-unemotional (CU) traits and impulsivity. However, there were ethnic differences in the factor structure of narcissism. No differences were found between ethnic groups in mean levels of CU traits and impulsivity. Finally, the association between impulsivity and self-reported delinquency was stronger for native Dutch than for immigrant juveniles. Further research is needed in order to make the treatment of juvenile delinquents with psychopathic traits in ethnic minority groups more effective according to the specific needs of these juveniles.     

Ensuring Employment Equity: Are Federal Diversity Programs Making a Difference?

Abstract

In the last two decades, many public sector agencies have instituted a wide array of “managing diversity” programs designed to remove barriers to the full participation of women and people of color. Meanwhile, agencies are also increasingly responding to pressure to develop measures to monitor performance of all of their programs. Yet there have been few efforts in place to measure the effectiveness of diversity management programs. This article argues that such an evaluation is essential, and offers a preliminary governmentwide estimation of the success federal agencies have had in breaking down these barriers. We found, for the most part, that there is little evidence that broad‐based diversity programs, nor any of their programmatic components, have created a more equitable work environment for women or people of color. We then examine the programs at two federal agencies with significant diversity efforts, in depth, and find again that the results have been mixed. While not meant to be the final word, we suggest that these findings can serve as the basis for generating greater discussion and analysis of these important, but under‐evaluated, programs.     

The difficulty of measuring support for democracy in a changing society: evidence from Russia

Measuring support for democracy in societies where democratic institutions do not exist or do not function well is a challenge faced by many researchers around the world. In societies moving either toward or away from democracy, the very meaning of ‘democracy’ is often in question and institutions and practices that go by the label of ‘democratic’ may vary widely from accepted norms. As a result, respondents are likely to interpret survey questions on democratic concepts in unpredictable ways. This article examines some of the ways respondents in non-democratic or imperfectly democratic countries may misinterpret the meaning of survey questions and consequently how their answers may mislead researchers. Previous research has focused on problems with abstract concepts like ‘democracy’. Evidence presented here – from interviews with Russians – shows that the problem is broader and covers more kinds of questions than previously thought. A strong potential for miscommunication also exists with more concrete questions about institutions and values, forced choices that encourage respondents to change the meaning of questions, and questions about trust in institutions.     

Accountability and evidence-based approaches: theory and research for juvenile justice

As part of the ‘accountability movement’ in juvenile justice, policy-makers, funding agencies, and the general public have called for greater accountability from agencies and organizations involved with youthful offenders. Within this context, performance measurement and monitoring, and use of evidence-based programs and practices, have emerged as recommended aspects of juvenile justice system operations nationwide. Little is known empirically, however, about the actual performance of juvenile justice systems or the real changes brought by contemporary reforms, and theory and research on the implementation and sustainability of evidence-based approaches have been slow to emerge. This paper will review the key aspects of the modern accountability movement in juvenile justice, and then discuss a recently proposed theory that may be useful in future examinations of juvenile justice system improvement efforts. A suggested research agenda also is presented.     

Studying civil society across the world: Exploring the Thorny issues of conceptualization and measurement

Abstract

The debate about the usefulness of the civil society concept for social analysis has reached a critical stage and calls for its abandonment are mounting. To prove its relevance for policy, practice and research, better operational concepts and more rigorous empirical research on civil society are required. This article examines the possibilities and pitfalls of cross-national civil society research as a crucial area of empirical civil society studies. It explores the definition, conceptualization, operationalization and measurement of civil society through a critical examination of existing international efforts at comparative civil society analysis. A functional approach to defining civil society and a two-dimensional operational concept of civil society, according to its (1) structural and (2) cultural features, are proposed as suitable tools to study the phenomenon cross-nationally. The article also reviews the Civicus Civil Society Index as an innovative tool to assess the state of civil society and discusses the insights and challenges emerging from its current application in more than 50 countries. The paper concludes that international comparative civil society studies are both possible and necessary, but cautions that more attention needs to be paid to the development of appropriate operational concepts and measurement models.

Validating a novel tool for coding body worn camera footage of police-community member interactions

Objectives

This study aimed to validate a tool for coding police body-worn camera (BWC) footage to measure the dynamics of police–community encounters, including items related to community members, officer performance, and situational outcomes.

Methods

Over 1000 BWC videos were scored by five coders who participated in an iterative interrater reliability exercise to improve the agreement. Krippendorf's alphas and a multilevel simultaneous component analysis were used to assess interrater reliability and the component structure of ratings, respectively. Bootstrapped and multilevel exploratory and confirmatory factor analyses were conducted to ascertain any underlying dimensions supporting officer and community member behavior, and cluster analyses were performed to examine whether interactions could be grouped into coherent categories.

Results

The lower bound of unweighted means of bootstrapped alphas ranged from 0.67 to 0.96 depending upon item type, and 21.60% of the total variance in raters was between-subjects. Factor analyses revealed only a single factor (“defensiveness”) underlying four items related to hostility directed toward officers by community members. Cluster analyses described seven categories that were highly overlapping but conceptually plausible with cluster silhouette means ranging from −0.06 to 0.13.

Conclusions

We validated a collection of interval-level coding metrics on a random sample of over 1000 interactions between police officers and community members recorded through BWCs. In doing so, we provide a roadmap for researchers and practitioners to effectively measure the dynamics of police–community encounters and officer performance within those encounters and a framework for addressing the validity and reliability of items in future studies involving the measurement of BWC footage.
