Characterizing The Patterns, Predictors, And Processes Involved In Recovery From Substance Use Disorders, Rebecca L. Smith

Theses and Dissertations

Alcohol and drug use disorders are associated with significant cost to individuals, families, and society.Approximately 40-75% of affected individuals remit from alcohol use disorders (AUD). Although the development of AUD is well studied, recovery from AUD and factors that contribute to recovery are not as well characterized. With the definition of recovery evolving towards a process rather than an outcome, there is a need to better understand psychosocial functioning and quality of life among individuals at different points in their recovery journeys. Concurrently, additional research is needed to understand the interplay between sources of recovery capital, individual differences in risk …

Breaking The Cycle: A Longitudinal Study Of Factors That Disrupt Peer Selection And Influence Processes Among Urban Youth, Kelly E. Oconnor

Theses and Dissertations

Having friends who engage in problem behavior (i.e., aggression, substance use, delinquency) has consistently been linked to adolescents’ own engagement in problem behavior. There are, however, several key gaps in the literature on peer influence. Few studies have considered the influence of friends’ prosocial behavior and there has been limited research to identify promotive factors that influence urban youths’ affiliation with peers who engage in problem and prosocial behavior across early adolescence, a time of heightened susceptibility to peer influence. The purpose of this study was to identify modifiable promotive factors that reduce adolescents’ problem behavior by decreasing exposure to …

Phenotype Extraction: Estimation And Biometrical Genetic Analysis Of Individual Dynamics, Kevin L. Mckee

Theses and Dissertations

Within-person data can exhibit a virtually limitless variety of statistical patterns, but it can be difficult to distinguish meaningful features from statistical artifacts. Studies of complex traits have previously used genetic signals like twin-based heritability to distinguish between the two. This dissertation is a collection of studies applying state-space modeling to conceptualize and estimate novel phenotypic constructs for use in psychiatric research and further biometrical genetic analysis. The aims are to: (1) relate control theoretic concepts to health-related phenotypes; (2) design statistical models that formally define those phenotypes; (3) estimate individual phenotypic values from time series data; (4) consider hierarchical …

When Empathy Only Goes So Far: Development Of A Trait Parochial Empathy Scale, Anna Maria C. Behler

Theses and Dissertations

Empathy, the ability to feel and/or understand another’s emotional state, plays a significant role in interpersonal interactions, mitigating hostility and enhancing affiliation and helping. However, empathy also biases interpersonal reactions. For example, at the group level empathy can become amplified towards members of their ingroup and blunted towards individuals in outgroups, a term called parochial empathy. Currently, no validated measures of parochial empathy at the dispositional level exist, and development of such a scale would be important to understanding the role of group-based emotions in prejudice and discrimination against outgroups. I conducted five studies to develop and validate a …

Understanding Knowledge Sharing Motivation In The Public Sector: Application Of Self-Determination And Person-Environment Fit Theories, Jaeyong Lee

Theses and Dissertations

Knowledge has been recognized as an important resource that should be carefully managed in order to enhance organizational competitiveness. Therefore, it is important to manage knowledge resources that have been learned and stored in organizations. Several scholars in the public administration literature have examined whether public service motivation (PSM) can help employees share their knowledge in ways that contribute to the effective functioning of public organizations. However, the mechanisms by which PSM influences individuals’ propensity to share knowledge have not been clarified by past research.

Against this background, at first, this study contributes to understanding the relationship between PSM and …
