Measuring the impact of public perceptions on child welfare workers

The Public Perceptions of Child Welfare Scale measures how the social environment influences child welfare workers, including their job satisfaction and intent to leave. Psychometric studies have validated the scale for private child welfare workers, but there are no validation studies with public agency staff. This study fills that gap, showing stigma and respect are important constructs that also predict worker intent to leave. This research found an additional construct, blame, which was not present in private worker validation studies. The scale provides an important tool for the field as we continue to build evidence for effective recruitment and retention.     

Supreme Court Elections: How Much They Have Changed,Why They Changed,and What Difference It Makes

This essay draws on four recent studies of elections to state supreme courts in the United States to probe widely perceived changes in the scale and content of electoral campaigns for seats on state supreme courts. 1 Evidence from these studies and other sources indicates that changes have indeed occurred, though they are more limited than most commentaries suggest. These changes stem most directly from trends in state supreme court policy that have attracted interest‐group activity, especially from the business community. Like their extent, the effects of change in supreme court campaigns have been meaningful although exaggerated by many observers. What we have learned about changes in supreme court elections has implications for choices among selection systems, but those implications are mixed and complex.     

Quantification of human mitochondrial DNA using synthesized DNA standards

Successful mitochondrial DNA (mtDNA) forensic analysis depends on sufficient quantity and quality of mtDNA. A real-time quantitative PCR assay was developed to assess such characteristics in a DNA sample, which utilizes a duplex, synthetic DNA to ensure optimal quality assurance and quality control. The assay's 105-base pair target sequence facilitates amplification of degraded DNA and is minimally homologous to nonhuman mtDNA. The primers and probe hybridize to a region that has relatively few sequence polymorphisms. The assay can also identify the presence of PCR inhibitors and thus indicate the need for sample repurification. The results show that the assay provides information down to 10 copies and provides a dynamic range spanning seven orders of magnitude. Additional experiments demonstrated that as few as 300 mtDNA copies resulted in successful hypervariable region amplification, information that permits sample conservation and optimized downstream PCR testing. The assay described is rapid, reliable, and robust.
