Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.     

The Impact of Child‐Parent Psychotherapy on Child Dependency Court Outcomes

Although parental compliance with court orders in child welfare cases is key to achieving physical parent‐child reunification and successful case closure, little research has examined how parent‐child relationship‐focused rehabilitative services uniquely influence case outcomes. This project fills this gap by investigating links between court ordering of and parental participation in Child‐Parent Psychotherapy (CPP) with court outcomes. Data were obtained from court records of 448 court‐involved parents. Hierarchical regressions revealed that greater participation in CPP led to reunification and successful case closure but not faster case closure. Courtroom professionals should consider parent‐child relationship‐based therapies as tools for achieving child welfare goals.     

Selecting Constitutional Judges Randomly

This article discusses from the perspective of democratic theory an innovative proposal for the selection of constitutional, supreme court, or federal judges that aims at combining the values of expertise and political independence. It consists in combining a certification process – selecting a pool of properly qualified candidates – with a random selection among this pool. We argue that such selection procedure would better respect the separation of powers and the specific legitimacy of courts, and we champion this two‐stage mechanism vis‐à‐vis other, more traditionally employed, selection procedures. We then deal with a diversity of objections to our proposal and conclude by taking stock of both its virtues and limitations.     

Exploring the Effects of North–South and South–South Research Collaboration in Emerging Economies,the Colombian Case

International research collaboration (IRC) is associated with both positive and negative effects on the performance of research in emerging economies. While some authors claim that North–South collaborations improve scientific quality and visibility for Southern countries, others claim that it may entail the reorientation of research to comply with Northern agendas. South–South collaborations are thought to increase the focus on local affairs, therefore leading to a relatively small number of scientific international publications appearing in “high quality” journals. Research on the impact of IRC beyond publications in international journals has been neglected despite the importance of other products in knowledge creation. This research uses a broad range of scientific outputs to empirically assess such assumptions and explore the outcomes of IRC in Colombia. Results from multivariate regressions and nonparametric analyses show that, contrary to common assumptions, Colombian research teams collaborating with partners from the global South report higher scientific production, while those collaborating with Northern countries seem to contribute to local knowledge the most.     

Government Communication Effectiveness and Satisfaction with Police Performance: A Large‐Scale Survey Study

For the last two decades, performance management theories and practices have focused on outcome‐oriented management but have paid little attention to the role of public communication. Using multiple large data sets from Kansas City, Missouri, for 2009–14, this research suggests that the perceived effectiveness of public communication has a more substantial impact on public satisfaction with police protection and crime prevention than neighborhood crime rates and broken windows factors and that perceived effectiveness moderates the negative impact of crime rates. After controlling for residents’ demographic characteristics, the authors find that the perceived effectiveness of communication is associated with public satisfaction with the content and quality of the city website and the government television channel. The implications for public safety management and police–citizen relations as well as directions for future research on public communication strategies and public performance management are presented.     

Ideologically Sophisticated Donors: Which Candidates Do Individual Contributors Finance?

Individuals are the single largest source of campaign contributions, yet we know little about their motivations. For instance, the existing literature questions whether individual contributors sophisticatedly differentiate among candidates according to policy positions, particularly among same‐party candidates. We analyze this issue by combining data from a new survey of over 2,800 in‐ and out‐of‐state donors associated with the 2012 Senate elections, FEC data on contributors’ professions, and legislative records. Three major findings emerge. First, policy agreement between a donor's positions and a senator's roll calls significantly influences the likelihood of giving, even for same‐party contributors. Second, there is a significant effect of committee membership corresponding to a donor's occupation; this holds even for donors who claim that other motivations dominate, but it does not appear to be motivated by an expectation of access. Third, conditional upon a donation occurring, its size is determined by factors outside a legislator's control.
