Assessing Structural Variation In And Out Of The Classroom: Characterizing Structural Variation Within Campanula Americana And Effects Of Long Read Sequencing On Students Learning, Tyler Gandee

Masters Theses, 2020-current

Cytonuclear incompatibilities are proposed to be one of the first genetic barriers to arise during speciation, so understanding the underlying evolutionary forces that contribute to cytonuclear incompatibilities is important. Many studies have looked at SNP level variation in the plastid genome and its relationship with cytonuclear incompatibility, but no studies have examined structural variation and its relationship to cytonuclear incompatibility, particularly at the early stages of speciation, i.e. within species. Campanula americana is a great system for this because it exhibits cytonuclear incompatibility and the family in which it is found, the Campanulaceae, exhibits rapidly evolving plastid genomes, including …

Measuring Alumni Career Outcomes: A Validity Study, Mason Jones

Masters Theses, 2020-current

Higher education experiences routine scrutiny as the cost continues to rise and evidence of a return on investment is variable. Higher education institutions would benefit from measuring post-graduate outcomes to better articulate their impact. The current study examines the factor structure and measurement invariance of the National Alumni Career Mobility (NACM) a 25-item survey, that is widely used to assess alumni career outcomes. Prior psychometric reports for the NACM purported two different factor structures: a five-factor and bifactor model. National reports disaggregated the data by demographic variables, including first-generation status. Disaggregation by first-generation status is problematic given the lack of …

Dynamics Of Skin-Based Gene Expression In Red-Sided Garter Snakes (Thamnophis Sirtalis Parietalis): Sex And Seasonal Influences, Emily C. Plant

Masters Theses, 2020-current

The skin is the key organ regulating the animal-environment interface and is particularly sensitive to the abiotic factors of temperate environments, such as extreme cold and aridity during winter. Previous research found that, in the skin, temperate birds and reptiles upregulate expression of lipid synthesis genes to prevent tissue freezing and evaporative water loss in winter. My study species, the red-sided garter snake (Thamnophis sirtalis parietalis), has seasonally variable skin lipid composition, and females produce a modified set of these lipids that function as a sex pheromone. The pheromone is maximally produced in the spring breeding season following …

Hatred Unveiled: Femininity, Masculinity, And The Duality Of The Female Klanswoman From 1923 – 1987, Ashley Tokarz

Masters Theses, 2020-current

The Ku Klux Klan of the post-Reconstruction era in American history is a well-known and frequently studied domestic terrorist organization. The KKK was born of lost cause ideology, and their intended purpose was to preserve southern society as it had been – that is, a society founded on white supremacy – through racial terror and violence. Although the KKK dissolved in less than a decade, the terrorist organization was ‘born again’ during the 1920s. This Klan was markedly different from the first. It grew to include millions of members, including elected officials, and was nationwide at its height. Yet, perhaps …

“If We Don't Get The Help That We Need, What Does That Say About The Future For Americans?”: A Rhetorical Analysis Of Public Responses To Ohio Environmental Disasters, Kaitlin M. Gold

Masters Theses, 2020-current

This thesis examines three case studies surrounding various Ohio environmental disasters and controversies. In particular, I explore how the public has resisted and asserted themselves through advocacy measures to ensure that their homes and communities are safe. The case studies examine how the state of Ohio has evaded responsibility and not taken action, and thus how the public has attempted to resist those efforts through various means. While Olson and Goodnight’s (1994) conception of oppositional arguments acts as a methodological backbone to the thesis, each case study employs other specific tools of rhetorical analysis to better understand each chapter and …

Role Of Dunc-13 Isoforms In Alcohol Sensitivity In Drosophila, Makenzie Havard

Honors Theses

Functional alcohol tolerance is an adaptation made by the nervous system to high doses of alcohol, and is seen by a significant reduction in sensitivity to this drug. This tolerance is a significant contributing factor in the progression to Alcohol Use Disorders. A major goal of alcohol research is to understand how alcohol induces this tolerance. Dunc13 is a presynaptic active zone protein essential in synaptic vesicle docking and priming. Alcohol binds to the C1 domain of Dunc13 at physiological concentrations, which inhibits Dunc13 from binding Diacylglycerol. This inhibition is predicted to reduce Dunc13 activity and presynaptic activity. Yet, genetically …

Relations Between Parent Reports Of Effortful Control And Behavioral Measures Of Executive Function In Toddlers, Racheal Embry

Honors Theses

Recent proposals have identified many commonalities in conceptualizations of effortful control and executive function (EF, e.g., Zhou, Chen, & Main, 2012). However, the overlap of effortful control and EF during periods of emerging regulation in toddlerhood has not been thoroughly investigated. In the present study, I examined the relationship between effortful control and EF in 14, 18, and 24 month old toddlers by a combination of in-lab tasks and parent report measures. Results revealed few relations between effortful control and EF during this time. The lack of overlap between effortful control and EF may be explained by a number of …
