Regression Discontinuity Designs Based on Population Thresholds: Pitfalls and Solutions

In many countries, important features of municipal government (such as the electoral system, mayors' salaries, and the number of councillors) depend on whether the municipality is above or below arbitrary population thresholds. Several papers have used a regression discontinuity design (RDD) to measure the effects of these threshold‐based policies on political and economic outcomes. Using evidence from France, Germany, and Italy, we highlight two common pitfalls that arise in exploiting population‐based policies (compound treatment and sorting), and we provide guidance for detecting and addressing these pitfalls. Even when these problems are present, population‐threshold RDD may be the best available research design for studying the effects of certain policies and political institutions.     

The Role of Mentor Type and Timing in Predicting Educational Attainment

Having an adult mentor during adolescence has been found to predict academic success. Building on previous work, the present study examined interactions between the type of mentor (i.e., kin, teacher, friend, or community), the time that mentor became important (i.e., before, during, or after high school), and the ethnicity of the protégé in predicting educational attainment in young adulthood. Analyses used Waves III and IV of the National Longitudinal Study of Adolescent Health (N = 2,409). Participants’ ages ranged from 18 to 27 (M = 21.75, SD = 1.79). The sample was 56.7 % female and nationally representative of ethnic diversity. Analyses showed that having a teacher-mentor was more predictive of educational attainment than having other types of mentors and that overall, having a mentor after high school predicts the most educational attainment. Kin- and community-mentors appeared to be more important to educational attainment during and before high school, respectively. Findings were consistent across ethnic groups. Overall, results highlight the value of teacher-mentors throughout childhood, adolescence, and early adulthood and our study further suggests that different types of mentors may be particularly useful at specific points in development.     

Willingness to Self-Disclose among Late Adolescent Female Survivors of Childhood Sexual Abuse

The primary aim of this study was to compare the willingness of sexually abused (n = 22) and non–sexually abused (n = 36) late adolescent women to self-disclose both general and sexual information to strangers and intimate partners. Results, based on a sample of college women, indicate that those who were sexually abused in childhood are less likely than nonabused counterparts to be highly disclosing of sexual and general information to intimate partners. Avoiding extensive disclosure of personal information to intimate partners may serve to keep survivors of abuse at a relatively safe distance from their own dysphoric feelings and suggests that mistrust of others is an ongoing issue for this population.     

Eyewitness Testimony in Occupational Accident Investigations: Towards a Research Agenda

Accident investigation is frequently cited as the cornerstone of an effective occupational health and safety program. We suggest that the literature on accident investigation is based on a model of witnesses as neutral and accurate recording devices. The literature on eyewitness testimony and criminal investigation offers strikingly different conclusions. We review these findings and point to their implication for research on accident investigation in occupational health and safety contexts.     

Is Public Management Neglecting the State?

Public management is a domain of research that is now roughly three decades old. Researchers in this area have made important advances in understanding about the performance of public organizations. But questions have been raised about the scope and methods of public management research (PMR). Does it neglect important questions about the development of major institutions of the modern state? Has it focused unduly on problems of the advanced democracies? Has it made itself irrelevant to public debates about the role and design of government, and the capacity of public institutions to deal with emerging challenges? This set of eight short essays were prepared for a roundtable held at the research conference of the PMR Association at the University of Aarhus in June 2016. Contributors were asked to consider the question: Is PMR neglecting the state?     

Enhancing Information Sharing in Family Drug Courts: A Lean Six Sigma Case Study

Given the variety of stakeholders involved in cases within family drug courts, efficient communication and information sharing, which are needed to support decision‐making, can be quite challenging. Through a case study in one family drug court system, this research employed an action research approach to improve the information sharing process following the Lean Six Sigma methodology. The solutions implemented through this study contributed to improving the quality of the services provided by this court system and its overall productivity. In addition, this research extends our knowledge about methods for improving court systems from which others can learn to guide future improvement efforts.     

One Myth of the Classical Natural Law Theory: Reflecting on the “Thin” View of Legal Positivism

Much controversy has emerged on the demarcation between legal positivism and non‐legal positivism with some authors calling for a ban on the ‐as they see it‐ nonsensical labelling of legal philosophical debates. We agree with these critics; simplistic labelling cannot replace the work of sophisticated and sound argumentation. In this paper we do not use the term ‘legal positivism’ as a simplistic label but identify a specific position which we consider to be the most appealing and plausible view on legal positivism. This is the view advocated by Gardner in his paper 'Legal Positivism: 5½ Myths’ (Gardner 2001 , 199), where he carefully scrutinises the most convincing and unifying postulates of legal positivism, which he calls “the thin view”. The study shows that this thin view presupposes an empirical conception of action that is untenable and implausible since it makes acts of engagement with the law unintelligible to an observer of such acts.
