Framing The Problem To Meet The Policy Solution: An Embedded Mixed Methods Case Study Of The 2017 Michigan Opioid Laws, Leandra Hawkins Burke

Dissertations

The opioid crisis presents a wicked problem for public administration. Hundreds of thousands of people have died from opioid overdoses in the United States, and countless others have experienced severe opioid-related physical, psychological, and socioeconomic harms. Countering the opioid crisis has been difficult due to interdependencies across different drugs and multiple pathways for abuse and dependence. Many scholars, health providers, and politicians have called for a broad public health approach to combat the opioid crisis, but the full expanse of what that would entail has not yet been realized. What has been demonstrated is that interactions targeting a single aspect …

Examination Of The Association Between Parent Beliefs About Injury And Supervision Behavior, Felicia Acelia Diaz

Dissertations

Unintentional Injuries are the leading cause of death for children in the United States (Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, 2021). Several studies have indicated that caregiver beliefs (such as locus of control) are associated with children’s injury risk (Damashek et al., 2005), but few studies have examined whether caregiver beliefs about injury are related to caregiver’s injury prevention behaviors, such as caregiver supervision. Examination of caregiver beliefs regarding supervision revealed that caregiver’s degree of belief in the preventability of childhood injuries predicted self-report scores on several measures of supervision. Caregiver’s degree of …

Multiple Monochromatic Subgraphs In Edge-Colored Graphs, Emma Felicity Jent

Dissertations

Ramsey theory, though a relatively young branch of mathematics, has captivated the attention of graph theorists, combinatorialists, and theoretical computer scientists alike through its raw beauty, versatility, and powerful applications. Before it emerged as a branch of mathematics, the central idea of Ramsey theory appeared in the form of three lemmas in three separate papers by three different mathematicians working on three distinct areas of research. The first such lemma was published by David Hilbert in 1892, followed by the second lemma published by Issai Schur in 1916. However, Frank Ramsey’s renowned lemma, published in 1930, compelled mathematicians to establish …

One Step Closer To Greater Understanding! Does A Correlation Exist Between Fluid Intelligence And Player Rank In League Of Legends?, Evan Miller

Dissertations

Chess, one of the oldest modern games, has long been a model domain for expertise research. In comparison, research on video games has historically been influenced by moral panic. Cycles of moral panic tend to revolve around preconceived notions of threats, held at a societal level (typically by older generations). Politicians, quick to capitalize, then advocate for policy change based upon their constituents’ fears. Concurrent media reports draw further attention to the issue, amplifying the perception of harm. As the panic escalates, pressure is placed on scientific communities to perform confirmatory (not exploratory) research. This fundamentally biased approach to research …

When Opportunity Knocks, Do Dark Personality Traits Aid In Students’ Rationalization Of Academic Misconduct?, Jacqueline R. Strowd

Dissertations

Concerns about academic misconduct are receiving increased attention within academia due to a proliferation of advanced technologies and reports of the high prevalence with which students engage in misconduct. Contextual factors (e.g., peer acceptance, opportunity) appear to be stronger predictors of students’ propensity for academic misconduct than individual factors (McCabe & Trevino, 1997). The Fraud Triangle Theory (i.e., pressure, opportunity, rationalization) has been adapted to this context and provides a useful theoretical model for considering contextual factors (Cressey, 1973; Wolfe & Hermanson, 2004). Research integrating this theory with the Dark Triad (i.e., Machiavellianism, narcissism, psychopathy) suggests that these traits may …

Spatial Distributions And Occupancy Dynamics Of Carnivores In A Central Hardwood Forest, Maximillian Larreur

Dissertations

Extirpation of apex predators, caused primarily by anthropogenic alterations to natural environments and persecution, has led to mesocarnivore release in these areas. Mesocarnivore release is an ecological phenomenon in which mesocarnivores thrive in the absence of apex predator dominance within the carnivore hierarchy. Mesopredators fill this dominant role on the landscape as de facto apex predators, however, this can lead to changes in inter-guild species space use, predator-prey dynamics, activity patterns, and interspecific competition. Understanding patterns in wildlife spatial distributions, which indicate variability in habitat space use across spatiotemporal scales, is critical for developing effective management and conservation plans and …

Human Resource Management And Black Teachers’ Employee Experience In K-12 Urban Public Schools, Danielle Renee Cooper-Williams

Immune Modulation Affects Olfactory Glomerular Recovery In Zebrafish, Bonnie E. Ebendick

Dissertations

Adult zebrafish regenerate neurons throughout their lifetime and exhibit rapid recovery from neuronal damage with support from their immune system, making them an excellent model for studying neuroinflammation and brain repair mechanisms. When olfactory sensory neurons are lesioned, their cell death stimulates the immune system by activating microglia and other immune cells in the olfactory bulb, initiating tissue repair and neuronal replacement. This dissertation investigates how the immune system influences recovery from neuronal damage, testing the hypothesis that immune perturbation in zebrafish alters neural recovery.

To investigate the link between immune function and neuronal regeneration, zebrafish received a unilateral lesion …

Mexican Americans’ Attitudes Toward Mexican Immigrants In The United States, Sandra Daisy Espinoza Montes

Applying Transcriptomics For Technology Development And Conservation In North American Marine Organisms, Cory Von Eiff

Dissertations

RNA biology is a rapidly expanding field, with many avenues of discovery among marine organisms. In this study, we analyze both mollusks and sawfish. First, we perform an evaluation of sRNA biogenesis pathways throughout Mollusca, with emphasis on the easter oyster, Crassostrea virginica. Understanding these molecules prescribes RNAi-based gene silencing approaches, benefiting genetic investigation and biotechnology. Similar to other animal groups, mollusks have conserved microRNAs (miRNAs), with some shared with ecdysozoans and deuterostomes; however, there is no evidence of an endogenous small interfering RNA (siRNA) pathway. These results suggest that long double-stranded RNA (dsRNA)-based RNAi is not appropriate for gene …
