Ownership Conversion As A Solution For Ex Post Agency Problems: The Case Of Franchising, Erik Tristan Markin Jan 2019

Ownership Conversion As A Solution For Ex Post Agency Problems: The Case Of Franchising, Erik Tristan Markin

Electronic Theses and Dissertations

This dissertation examines the strategic decision of franchising firms to convert company-owned outlets to franchise contracts in response to persistent agency problems. Moreover, this study investigates how franchisor-level, market-level, and outlet-level characteristics interact with this relationship. Using a longitudinal sample of company-owned fast-food restaurants, I find that increased agency problems at focal restaurants increases the likelihood of being converted to a franchise and that this relationship is moderated by both franchisor- and outlet-level characteristics but not market-level characteristics. Limitations and future research opportunities are discussed.

Empirical Support For Multidimensional Treatment Foster Care (Mtfc): A Critical Review, Jennifer Marie Ladner-Graham

Electronic Theses and Dissertations

Multidimensional Treatment Foster Care (MTFC), initially intended as a treatment for chronic juvenile offenders (adolescents having multiple contacts with the juvenile justice system), was designed as an alternative to placement within group facilities. MTFC allows the adolescent to remain in the community while receiving individual and family-based interventions. These interventions are dedicated to decreasing risk factors associated with offending (e.g., poor parental supervision, association with delinquent peers, poor academic performance) and increasing protective factors (e.g., effective parenting practices, healthy relationships with supportive peers, increased school involvement). MTFC has been utilized to meet the needs of a variety of populations (e.g., …


Validating Military Culture: The Factor Analysis Of A Military-Related Adaptation Of Acculturation, Mathew A. Tkachuck Jan 2019

Validating Military Culture: The Factor Analysis Of A Military-Related Adaptation Of Acculturation, Mathew A. Tkachuck

Electronic Theses and Dissertations

The concept of acculturation has a long history, and measures of the construct attempt to assess the degree to which attitudes and behaviors reflect the interaction between different cultures. Berry’s acculturation framework (1997) is arguably the most empirically-supported and well-known model of acculturation. Berry’s model posits that an individual may have difficulty appropriately adapting to a culture different than his or her own depending on how much they are oriented to either culture. Moreover, Searle and Ward (1990) hypothesized that an individual’s acculturation orientation, in addition to how different the dominant and non-dominant cultures are from one another, impacts psychological …


Nonmedical Use Of Prescription Drugs Among Young Adults: An Examination Of Anxiety Sensitivity, Distress Tolerance, And Emotion-Driven Impulse Control Difficulties, Sara Michelle Witcraft Jan 2019

Nonmedical Use Of Prescription Drugs Among Young Adults: An Examination Of Anxiety Sensitivity, Distress Tolerance, And Emotion-Driven Impulse Control Difficulties, Sara Michelle Witcraft

Electronic Theses and Dissertations

Individuals with anxiety disorders are significantly more likely to develop substance use disorders than those without anxiety disorders (Kessler & Greenberg, 2002). Despite a sizeable body of literature focused on etiological and maintenance factors underlying the co-occurrence of substance use and anxiety pathology, this relationship remains poorly understood. Transdiagnostic factors, specifically distress tolerance, anxiety sensitivity, and emotion-driven impulse control difficulties, have been posited to contribute to the relationship of anxiety and substance abuse, and in particular, nonmedical use of prescription drugs (NMUPD; Dennhardt & Murphy, 2013; Wolitzky-Taylor et al., 2015). The current study examined group differences among the aforementioned transdiagnostic …

On The Relationship Between Resilience, Meaning, And Hardiness: A Bi-Factor Exploratory And Confirmatory Analysis, Lauren Weathers Jan 2019

On The Relationship Between Resilience, Meaning, And Hardiness: A Bi-Factor Exploratory And Confirmatory Analysis, Lauren Weathers

Electronic Theses and Dissertations

Meaning in life, resilience, and hardiness have been conceptualized in a variety of ways. Some researchers theorize that these constructs share significant overlap. The goal of the current study was to examine how much overlap exists between these concepts. Three thousand and ten participants from a university in the Midwest and a university in the South completed measures of meaning in life, resilience, and hardiness. It was hypothesized that some items from these measures would create a unidimensional model while some items would create multidimensionality. Hypotheses that incorporated both models were important as there is disagreement within the literature with …

Decolonial Resistance In Latinx Writings From Peru To The United States: A Portfolio, Isabel Norwood Jan 2019

Decolonial Resistance In Latinx Writings From Peru To The United States: A Portfolio, Isabel Norwood

Electronic Theses and Dissertations

This collection begins with the premise that colonial relationships manifest in ways beyond exploitation of one nation by another. It relies on the decolonial theory of Walter D. Mignolo in its assumption that imbalances of power in the realms of race gender sexuality and class are fundamentally colonial. With this more expansive understanding of coloniality in mind I examine resistance to colonial exploitation in a range of texts from across the Americas. The first essay in this collection explores the role of the guinea pig in Andean food culture arguing that the continued consumption of guinea pig represents a form …
