Developmental Validation of the Quantifiler® Duo DNA Quantification Kit for Simultaneous Quantification of Total Human and Human Male DNA and Detection of PCR Inhibitors in Biological Samples*

Abstract: The Quantifiler^® Duo DNA Quantification kit enables simultaneous quantification of human DNA and human male DNA as well as detection of inhibitors of PCR in a single real-time PCR well. Pooled human male genomic DNA is used to generate standard curves for both human (ribonuclease P RNA component H1) and human male (sex determining region Y) specific targets. A shift in the cycle threshold (C_T) values for the internal positive control monitors the presence of PCR inhibitors in a sample. The assay is human specific and exhibits a high dynamic range from 0.023 to 50 ng/μL. In addition, the multiplex assay can detect as little as 25 pg/μL of human male DNA in the presence of a 1000-fold excess of human female DNA. The multiplex assay provides assessment of the DNA extract and guidance for the selection of the appropriate AmpFℓSTR^® Amplification Kit to obtain interpretable short tandem repeat profiles.     

Power in Editorial Positions: A Feminist Critique of Public Administration

Journal editors serve a vital, powerful role in academic fields. They set research priorities, serve as gatekeepers for research, play a critical role in advancing junior scholars as reviewers and eventually into editorial roles, build extensive networks, and gain valuable insight into the behavior and preferences of reviewers and scholars. This article analyzes data collected from leading public administration journals in 2017 to investigate the role of women as gatekeepers of public administration knowledge. The data illustrate a clear underrepresentation of women on editorial boards. Drawing from these data, research on journal editorships, and feminist theory, the authors present a critique of the current state of public administration research and a discussion of a way forward. They conclude with a proposal for how all public administration scholars (junior, senior, men, and women), journal leadership, and academic departments can move toward increasing women's representation in these important positions.     

Cost‐Effectiveness of Early Childhood Interventions to Enhance Preschool: Evidence from a Randomized Experiment in Head Start Centers Enrolling Historically Underserved Populations

We evaluate the cost‐effectiveness of two early childhood interventions that use instructional coaching and parent coaching as levers for improvement. The study design allows us to compare the individual effects of each intervention as well as their combined effect on student outcomes. We find that teachers receiving instructional coaching improve their use of evidence‐based instructional practices, while families receiving parent coaching show increases in numerous responsive parenting behaviors associated with positive child outcomes. Both interventions demonstrate positive impacts on students, but only parent coaching shows statistically significant effects across a range of student outcomes. Instructional coaching alone is substantially less costly and may therefore be the most cost‐effective of the three treatment conditions; however, small sample sizes limit our ability to reach definitive conclusions. Policy simulations suggest that implementing these interventions could raise the overall cost‐effectiveness of Head Start by at least 16 percent.     

Alternative South–South development collaboration? The role of China in the Coega Special Economic Zone in South Africa

Aid, in the form of financial aid and investment, has become increasingly prevalent in both bilateral and multilateral partnerships in the BRICS. In Africa, the Forum on China–Africa Cooperation provides the official framings for forms of development assistance to the continent, with financial forms of aid available through the New Development Bank and the China–Africa Development Bank (CADFund). This article explores how Chinese international development assistance has influenced South Africa's economic growth and development strategies and is reshaping South Africa as “gateway” to Africa and continental leader. Special economic zones (SEZs) have become a prioritised form of BRICS development collaboration particularly in terms of Chinese trade and investment expansionism into Africa through South Africa. Chinese international development assistance and foreign direct investment in South Africa in particular are very notable and have been strengthened during the Chinese official state visit prior to the Johannesburg BRICS Summit in 2018. The article critically analyses the development policy discourse on BRICS spearheading an alternative model of South–South international cooperation by examining the Coega SEZ in South Africa, hailed as the most SEZ in Africa. The article critically examines the development alternative potential of the Coega SEZ.     

Corruption experiences and attitudes to political,interpersonal, and domestic violence

It is understood that corruption can change the incentives to engage in political violence. However, the scope for corruption to change attitudes toward the permissibility of violence has received less attention. Drawing on Moral Foundations Theory, we argue that experiences of corruption in the social environment are likely to shape individual attitudes toward violent behavior. Using Afrobarometer data, we document a statistically significant and sizable relationship between an individual's experience of paying bribes and their attitudes to political, interpersonal, and domestic violence. These relationships are evident, and not significantly different, for men and women and are robust to the inclusion of variables capturing the local incidence of corruption, local norms regarding violence, and a proxy for the local incidence of violence with the community. Corruption is associated with permissive attitudes to violence even after controlling for the perceived legitimacy of the police and courts.     

Sex differences in the likelihood of arrest

Using data from the new National Incident-Based Reporting System (NIBRS), this study analyzed the impact of a criminal offender's sex on the likelihood of arrest for 555,752 incidents of kidnapping, forcible rape, forcible fondling, robbery, aggravated assault, simple assault, and intimidation in nineteen states and the District of Columbia during 2000. The data used in this study advanced the literature by enabling the authors to determine the likelihood of arrest for males and females based on sex-specific offending as reported by crime victims. Controlling for offense seriousness and a variety of other factors, logistic regression results showed that the probability of arrest for females was 28 percent lower for kidnapping, 48 percent lower for forcible fondling, 9 percent lower for simple assault, and 27 percent lower for intimidation than for males. A supplemental analysis also revealed that Black females had a higher probability of arrest than did White females for aggravated and simple assault. No discernable impact of an offender's sex on the prospect of arrest was noted for the crimes of forcible rape and robbery. Overall, these findings suggest that the lower arrest rate for females is partly the result of leniency shown women by law enforcement personnel.     

Felony voir dire

The practice of voir dire has a venerable history in the United States. However, despite numerous historical and legal discussions of the topic, and the increased participation of social scientists in the process, few empirical studies have been conducted on what actually occurs during voir dire. The lack of normative data is especially troublesome in the face of recent attacks on the process itself and numerous proposals to drastically limit or even prohibit what many regard as an important criminal justice safeguard—attorney-conducted voir dire in felony trials. This exploratory study attempts to provide some insight into the nature and content of felony voir dire. Our results—based on direct observation as well as juror interview responses—suggest that much of the criticism and calls for drastic reform may be misplaced.
