Federal, state, and local governments: evaluating their separate roles in US growth

We use US county level data from 1970 to 1998 to explore the relationship between economic growth and government employment at three levels: federal, state and local. Increases in federal, state and local government employments are all negatively related to economic growth. We find no evidence that government is more efficient at lower levels. While we cannot separate out the productive and redistributive services of government, we document that the county-level income distribution became slightly more unequal from 1970 to 1998. We conclude that a release of government-employed labor inputs to the private sector would be growth-enhancing.     

A Comparison of the Values and Commitment of Private Sector, Public Sector, and Parapublic Sector Employees

This study investigated differences in general values, work values and organizational commitment among 549 private sector, public sector, and parapublic sector knowledge workers. No differences in general values were observed across sectors, although five significant work value differences were revealed: parapublic employees value work that contributes to society more than public servants, who value it more than private sector employees; parapublic employees value opportunities for advancement less than both public and private sector employees; public servants value intellectually stimulating and challenging work more than parapublic employees; and private sector employees value prestigious work more than public servants. Private sector employees displayed greater organizational commitment than the employees in the other two sectors. Overall, the findings suggest only limited value differences among employees of the various sectors. The finding of some work value differences between employees in the public and parapublic sectors suggests that these two groups merit separate consideration in comparative studies such as this one.     

The relationship between education level and performance ratings of campus police officers

Data from 165 campus police officers at 16 campus police departments were used to investigate the relationship between educational level and performance of campus police officers. The results of the study indicated that education was significantly related to supervisor ratings of report writing proficiency (r=.29) and communication skills (r=20) but not discipline problems (r=−.01) or overall performance (r=.10). The relationship between education and report writing proficiency was moderated by years of police experience as education predicted performance in officers with five or more years experience but not those with less than five years experience.     

Quantitative PCR overestimation of DNA in samples contaminated with tin

Metals can pose challenges while conducting forensic DNA analysis. The presence of metal ions in evidence-related DNA extracts can degrade DNA or inhibit PCR as applied to DNA quantification (real-time PCR or qPCR) and/or STR amplification, leading to low success in STR profiling. Different metal ions were spiked into 0.2 and 0.5 ng of human genomic DNA in an “inhibition study” and the impact was evaluated by qPCR using the Quantifiler™ Trio DNA Quantification Kit (Thermo Fisher Scientific) and an in-house SYBR Green assay. This study reports on a contradictory finding specific to tin (Sn) ions, which caused at least a 38,000-fold overestimation of DNA concentration when utilizing Quantifiler Trio. This was explained by the raw and multicomponent spectral plots, which indicated that Sn suppresses the Quantifiler Trio passive reference dye (Mustang Purple™, MP) at ion concentrations above 0.1 mM. This effect was not observed when DNA was quantified using SYBR Green with ROX™ as the passive reference, nor when DNA was extracted and purified prior to Quantifiler Trio. The results show that metal contaminants can interfere with qPCR-based DNA quantification in unexpected ways and may be assay dependent. The results also highlight the importance of qPCR as a quality check to determine steps for sample cleanup prior to STR amplification that may be similarly impacted by metal ions. Forensic workflows should recognize the risk of inaccurate DNA quantification of samples that are collected from substrates containing tin.     

Self-Control and Racial Disparities in Delinquency: A Structural Equation Modeling Approach

The purpose of the present study is to examine the racial disparities of offending within the context of self-control theory. The study utilized data from the National Longitudinal Survey of Youth (NLSY79), to examine this effect. All concepts within self-control theory are examined: parental management, low self-control, and delinquency. Results from the study show partial support for Gottfredson and Hirschi’s (1990) self-control theory. The structure of the theory remained stable when controlling for both race, as well as peer pressure. Both theoretical and policy implications are given.     

The Role of Competition in Best Value: How Far Does it Differ from CCT?

This article investigates the role of ‘competition’ within Best Value (BV) and compares it with that of Compulsory Competitive Tendering (CCT). Utilising results of a survey of BV lead officers, the article reveals that ‘competition’ is not being used as widely as may have been expected. However, in terms of outcomes, services subject to BV seem to be at least as likely to be provided externally as would have been the case under CCT. Further analysis also considers the impact that party political control and service type have on the use and outcomes of competition.     

Race and Juvenile Incarceration: A Propensity Score Matching Examination

Disproportionate minority contact is an important issue in contemporary juvenile justice. Few studies have directly examined the link between race and judicial decision to incarceration. Using official data from Pennsylvania (n?=?41,561), this study added to this literature in two ways. This study used propensity score matching to obtain a purer estimate of the influence race has on the decision to petition a case to juvenile court. The results indicated that prosecutors use perceptual shorthand in making this decision that hinges on race. Specifically, blacks were more 1.28 times more likely than whites to have their case petitioned to juvenile court.
