Successfully Scaling Digital Technology Ventures: An Empirical Study Of The Strategic Choices That Maximize Firm Value, Scott Morris

Dissertations

Our study aims to understand the choices managers working for subscription-based digital ventures must make at arguably the most critical juncture of their firm’s lifecycle. With few slack resources to repair mistakes, managers at these scaling firms must make decisions that are larger in scope and scale than in the start-up phase. Tradeoffs are often required as decision-makers face choices such as investing more resources in sales and marketing to drive growth or in product development to improve quality and add new products or features. In many instances, the question is whether to forego some growth opportunities to maximize profitability …

Experiences And Perceptions Of Rural Postpartum Women With Substance Use Disorders Inclusive Of Opioids Regarding Their Care, Debra L. Kramlich

Dissertations

Perinatal opioid use and neonatal withdrawal continue to rise rapidly in the face of the growing epidemic of opioid addiction in the United States, with rural areas more severely impacted. Despite several decades of research and development of practice guidelines, maternal and neonatal outcomes have not improved substantially. This focused ethnography aimed to address that gap by exploring rural women's experiences and perceptions of care to inform development of efficacious, holistic models of care to improve outcomes for these women and their children. Participant observations, oral accounts and formal interviews, and artifact review (i.e., health records, any print and electronic …

Cumulative Advantage And Student Performance In General Chemistry: An Empirical Study At A Midwest Tier 1 University (2016-2019), Nicole Barvian

Dissertations

General chemistry (GC) plays a crucial role in the academic and career outcomes of students interested in postsecondary science, engineering and medicine. As a whole, chemistry education research literature has reported student attrition rates averaging from 25% to 35% for nearly a century. Student attrition rates can be attributed to a number of factors, including high school preparation (e.g. Tai et al. 2006), opportunity to learn (Carroll, 1989) and accumulated time and practice in a domain (e.g. Ericsson et al. 1993). The factors, in turn, are affected by mechanisms of social stratification, in particular, the social mechanism of cumulative advantage …

Sensing The Rhizosphere: Microbial Transcriptome Responses To Root Exudates And Redox-Active Metabolites, Ankita Bhattacharyya

Dissertations

The term “rhizosphere” describes the dynamic interface between plant roots and soil influenced by root exudates. It is a hotspot of microbial activity, plant-microbe, and microbe-microbe interactions. Distinct variations in bacterial diversity are thought to be driven by plant root exudates. However, the molecular details of these processes still remain unclear.

I addressed this gap by focusing on two strains, Pseudomonas synxantha 2-79 and Burkholderia lata 383, representing diverse groups of Gammaproteobacteria comprised of species with environmental, agricultural, and medical significance. In the first part of this project, we used a combination of metabolomics and RNA-seq to characterize transcriptome responses …

Human Capital Flight: Determinants Of Out-Migration Decisions Among Mississippi’S College Graduates, Felicia M. Bowens

A Computational Kinetics Model To Quantify Radiation Induced Chemical Products Of Atmospheric Gas Mixtures, Patrick Ables

Dissertations

This research is focused on the development of a computational model which will calculate the effects of radiation on the chemical composition of the atmosphere. The approach utilizes the open-source chemical kinetics toolkit Cantera to model the creation of radiation-induced reactant species within irradiated air mixtures. Chemical solutions are iteratively stepped toward chemical equilibrium within a ‘constantly stirred’ (homogeneous) reactor of fixed volume. Three different radiation chemistry models are implemented in several different pulsed and continuous radiation schemes. The first model includes the mechanisms and rates of a pulse radiation model from the literature to test the validity of the …

Davidsbündler: Robert Schumann, Theodor Kirchner, And An Intimate Musical World, Dandan Liu Powell

Dissertations

Theodor Kirchner is an accomplished Romantic composer in the nineteenth century. He wrote over one thousand piano pieces, and most of them have a strong influence by his mentor Robert Schumann.

The study of Kirchner and the relationship between Robert and Kirchner’s music is not sufficient. Clara Schumann, as the wife of Robert Schumann and the lover of Theodor Kirchner also inspired both composers’ music works. Therefore, this dissertation will focus on introducing Theodor Kirchner and …

Vicarious traumatization (VT) in the context of early career mental health professionals (MHPs) with personal trauma histories has been examined in the literature on a limited basis, particularly regarding the role that supervisory working alliance and shame could contribute to the effects of VT. Research questions asked: (a) Among early career MHPs who have a personal childhood trauma history, does shame mediate the relationship between personal childhood trauma history and VT? and (b) Among early career MHPs who have a personal childhood trauma history, does supervisory working alliance moderate the relationship between personal childhood trauma history and VT? These questions …

Exploring The Dimensions Of Lesbian, Gay, And Bisexual Affirmative Clinical Supervision, Lindsey N. Dollar

Dissertations

Graduate programs have continued to improve over time regarding incorporating training on LGB issues into coursework and practicum experiences with less emphasis on supervision. Since supervision is a major training area where therapists learn about clients and themselves, it becomes an important area for also teaching supervisees how to work with minority populations. However, relatively absent from discussions of cultural influences in supervision is a focus on LGB concerns, and missing is the ‘how to’ within the supervisory relationship. This quantitative investigation sought to learn how clinical supervisors with knowledge of LGB issues and people implement LGB-affirmative supervision, and to …
