Description
Many manmade chemicals used in consumer products are ultimately washed down the drain and are collected in municipal sewers. Efficient chemical monitoring at wastewater treatment (WWT) plants thus may provide up-to-date information on chemical usage rates for epidemiological assessments. The objective of the present study was to extrapolate this concept, termed 'sewage epidemiology', to include municipal sewage sludge (MSS) in identifying and prioritizing contaminants of emerging concern (CECs). To test this the following specific aims were defined: i) to screen and identify CECs in nationally representative samples of MSS and to provide nationwide inventories of CECs in U.S. MSS; ii) to investigate the fate and persistence in MSS-amended soils, of sludge-borne hydrophobic CECs; and iii) to develop an analytical tool relying on contaminant levels in MSS as an indicator for identifying and prioritizing hydrophobic CECs. Chemicals that are primarily discharged to the sewage systems (alkylphenol surfactants) and widespread persistent organohalogen pollutants (perfluorochemicals and brominated flame retardants) were analyzed in nationally representative MSS samples. A meta-analysis showed that CECs contribute about 0.04-0.15% to the total dry mass of MSS, a mass equivalent of 2,700-7,900 metric tonnes of chemicals annually. An analysis of archived mesocoms from a sludge weathering study showed that 64 CECs persisted in MSS/soil mixtures over the course of the experiment, with half-lives ranging between 224 and >990 days; these results suggest an inherent persistence of CECs that accumulate in MSS. A comparison of the spectrum of chemicals (n=52) analyzed in nationally representative biological specimens from humans and MSS revealed 70% overlap. This observed co-occurrence of contaminants in both matrices suggests that MSS may serve as an indicator for ongoing human exposures and body burdens of pollutants in humans. In conclusion, I posit that this novel approach in sewage epidemiology may serve to pre-screen and prioritize the several thousands of known or suspected CECs to identify those that are most prone to pose a risk to human health and the environment.

Description
Four Souvenirs for Violin and Piano was composed by Paul Schoenfeld (b.1947) in 1990 as a showpiece, spotlighting the virtuosity of both the violin and piano in equal measure. Each movement is a modern interpretation of a folk or popular genre, re- envisioned over intricate jazz harmonies and rhythms. The work was commissioned by violinist Lev Polyakin, who specifically requested some short pieces that could be performed in a local jazz establishment named Night Town in Cleveland, Ohio. The result is a work that is approximately fifteen minutes in length. Schoenfeld is a respected composer in the contemporary classical music community, whose Café Music (1986) for piano trio has recently become a staple of the standard chamber music repertoire. Many of his other works, however, remain in relative obscurity. It is the focus of this document to shed light on at least one other notable composition; Four Souvenirs for Violin and Piano. Among the topics to be discussed regarding this piece are a brief history behind the genesis of this composition, a structural summary of the entire work and each of its movements, and an appended practice guide based on interview and coaching sessions with the composer himself. With this project, I hope to provide a better understanding and appreciation of this work.

Description
Over the last few decades, specialized courts have received an increasing amount of research attention. The existing literature mostly supports drug courts and demonstrates their effectiveness in reducing recidivism and substance abuse, more generally (Belenko, 1998; Bouffard & Richardson, 2007; Gottfredson, Najaka, & Kearley, 2003). Whether the drug court model “works” across offender subgroups remains an open empirical question. The current study uses data originally collected by Rossman and colleagues (2003-2009) for the Multi-Site Adult Drug Court Evaluation (MADCE) to examine the effect of drug court participation on recidivism among unique offender subgroups. First, a context-specific risk score is used to examine recidivism outcomes. Second, offender subgroups are statistically created using latent class analysis (LCA). Recidivism outcomes are then assessed by subgroup, with these results compared to the initial measure of risk. Both analyses are performed using the full sample of drug court participants and the comparison groups. Finally, the third model uses a split sample analysis by court participation to explore the full effects of drug court. The findings of the present study contribute to the theoretical literature and help inform future policy regarding risk assessment and the treatment of offenders in drug courts.

Description
Child abuse and neglect is a devastating yet preventable social problem. Currently, early childhood home visitation services are the primary approach to preventing maltreatment and improving child well-being in the United States. However, existing literature suggests that improvement is needed regarding how home visitation professionals identify and respond to risk factors for child abuse and neglect. Although there is substantial multidisciplinary literature that investigates the utility of standardized measures to determine future risk for maltreatment, there has been minimal inquiry into the validity of early childhood home visitation assessment instruments to accurately identify and classify children and their families by their risk for future maltreatment. In response to the dearth in the literature, the purpose of this dissertation was to examine the utility of the Healthy Families Parenting Inventory (HFPI) to predict a family’s risk for future maltreatment. Families enrolled in Healthy Families Arizona, a child abuse and neglect prevention program, were followed for 12 months after the completion of the baseline HFPI to measure if the family had received an investigation of maltreatment from the public child welfare system. Bivariate results indicated that the generated risk classifications of the HFPI and the overall total composite score were related to the occurrence of a future maltreatment investigation. Specifically, the results from the binary logistic regression models provided evidence that as a family’s score increased on the inventory, the likelihood of receiving an investigation of maltreatment decreased. Further, significant relationships were found between a family’s score on several individual items of the HFPI and the occurrence of a maltreatment investigation. This dissertation concludes with a discussion of potential avenues of research on the topic of risk assessment in prevention programs serving at-risk families.
