Graduate Theses, Dissertations, and Problem Reports (ETD)

Developmental plasticity is the phenotypic variation between organisms that is caused by environmental interactions affecting the developmental systems of organisms. The research focused primarily on nutrition-responsive developmental plasticity. In this research we used the nutritionally determined head horn development of Onthophagus taurus to better understand the developmental mechanisms and genetic underpinnings of nutrition-responsive trait development. We focused specifically on altering the availability of specific nutrition-related primary metabolites, cholesterol and palmitic acid, identified in the activity of The Hedgehog pathway, a critical pathway in head horn development. By altering diet composition using cholesterol, reducing transcript expression of an acyltransferase gene, rasp …

Bullets, Breeding, And Biodiversity: An Analysis Of Trophy Hunting In South Africa's Green Wildlife Economy, Dave E. Knieter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Using a political ecology framework, I explore the relationship between international trophy hunting and South Africa’s private wildlife ranching industry. I interrogate the intersection of colonialism, capitalism, and conservation, which at its nexus are the discourses, policies, and logics that greenwash the production of nature. The proceeding chapters highlight a number of specific themes that problematize the neoliberalization of nature, including (i) the contradictions of imposing a market value to nonhumans; (ii) the operationalization of socioeconomic and environmental frameworks to justify trophy hunting and the breeding of nonhumans for profit; (iii) the use of African landscape and wildlife imagery to …

The Effect Of Newspaper Closure On Local Media Ecology, Cody David Nespor

Graduate Theses, Dissertations, and Problem Reports (ETD)

On August 31, 2019, the local newspaper of Youngstown, Ohio, The Vindicator, ceased publication after 150 years. The Vindicator’s closure left Youngstown as the largest city in the United State without a major newspaper. As local newspaper closures become more and more common across communities, there are questions on how, and if, the coverage and content those newspaper provide to their communities can be replaced or will simply be lost forever. This study has three research questions. Question one pertains to the amount of original reporting that will exist without The Vindicator. Questions two asks about the amount of locally …

Leaf Angle And Leaf Stomata Responses To Experimental Drought In Quercus Velutina And Acer Saccharum, Brittany Nichole Casey

Graduate Theses, Dissertations, and Problem Reports (ETD)

The possibility of increased severity and frequency of drought conditions, as a result of global climate variability, greatly complicates our ability to forecast future forest functions such as productivity and carbon sequestration. Assessing how tree species vary in their response to drought can aid in predicting the impact on forest ecosystems as a whole. Throughfall exclusion (TfE) experiments are potentially useful tools to simulate realistic drought conditions within intact forest ecosystems. We employed a TfE experiment during the 2018 growing season within the WV Land Trust’s Elizabeth’s Woods Nature Preserve, near Morgantown, WV, to assess the leaf angle and leaf …

Examining The Use Of Mhealth Technology For Weight Management: A Hybrid Effectiveness-Implementation Trial In Family Medicine, Laurel A. Brabson M.S.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Overweight and obesity are prevalent and problematic conditions in the United States and worldwide, and effective weight management interventions are underutilized. Efforts to improve weight management practices have focused almost exclusively on changing physician behavior, without considering the larger healthcare context or the reciprocal patient-physician relationship. The current study explored the possibility of leveraging technology to improve the implementation of weight management clinical practice guidelines and increase patient-physician weight management discussions. 100 patients of five family medicine physicians were randomly assigned to either complete a weight management mobile application (app) prior to their primary care visit (app condition), or to …

Regional Variation On Loanword Adaptation In Japanese, Yuki Hattori

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the variations of loanword abbreviations in Japanese dialects. When adopting foreign words into Japanese, phonological grammar is applied creating loanwords. When loanwords are introduced, Japanese phonological rules determine how to pronounce the new words; Japanese truncation styles are applied to shorten and abbreviate loanwords. Much like native Japanese words, regional variations can be observed in loanword abbreviations. In order to discover how variations are created, this study compares two dialects: the eastern Japanese dialect (standard dialect) and the western Japanese dialect (Kansai dialect). Despite a recent decrease in popularity, the Kansai dialect is still one of the …

Evaluating Use And Preference For Performance Feedback To Teach Instructional Strategies, Natalie Jones Shuler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Written and graphical feedback may be useful tools for supporting instructors because they require fewer scheduled meetings and provide instructors with permanent performance records. Although written and graphical feedback have been effective at improving some skills (e.g., use of praise), little is known about efficacy across a wider array of skills or about teacher preferences for these feedback types. Study 1 evaluated use of written and graphical feedback to increase opportunities to respond (OTRs) provided by three instructors of equine-assisted activities and therapies. Feedback increased OTRs for all three instructors. Additionally, all instructors showed untaught increases in praise when receiving …

Innovative Approaches To 3d Gis Modeling For Volumetric And Geoprocessing Applications In Subsurface Infrastructures In A Virtual Immersive Environment, Pragya Srivastava

Graduate Theses, Dissertations, and Problem Reports (ETD)

As subsurface features remain largely ‘out of sight, out of mind’, this has led to challenges when dealing with underground space and infrastructures and especially so for those working in GIS. Since subsurface infrastructure plays a major role in supporting the needs of modern society, groups such as city planners and utility companies and decision makers are looking for an ‘holistic’ approach where the sustainable use of underground space is as important as above ground space. For such planning and management, it is crucial to examine subsurface data in a form that is amenable to 3D mapping and that can …

Identifying Structure In Introductory Topology: Diagrams, Examples, And Gestures, Keith N. Gallagher

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite the prevalence of research in calculus, linear algebra, abstract algebra, and analysis in undergraduate mathematics, the teaching and learning of general topology is a largely unexplored area of research. Although enrollment in courses like linear algebra is often higher than that of topology, the study of students’ learning and understanding of topology is of great significance to the Research in Undergraduate Mathematics Education (RUME) community. Courses in topology present many students with their first experience in axiomatic reasoning and explicit interactions with mathematical structure, itself.

I present a thorough case study of Stacey, an undergraduate taking a first course …

Struggle For Sovereignty: An African-American Colonization Attempt And Delicate Independence In Mid-Nineteenth Century Central America, Matthew D. Harris

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis uses a series of United States foreign relations documents centered around an 1862 attempt by Abraham Lincoln to colonize parts of Central America with freed African Americans. Traditionally, these communications have been used by historians for U.S. foreign relations or Black resettlement history. Here, instead, this collection is used to display the major threats to Central American sovereignty in the mid-nineteenth century in their own words. The collection reveals that two of the threats were foreign imperialistic thought and racial instability. However, the third, and ultimately most destabilizing threat to the region, was the five nations' rivalry amongst …

A Flight Sensory-Motor To Olfactory Histamine Circuit Mediates Olfactory Processing Of Ecologically And Behaviorally Natural Stimuli, Samual P. Bradley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Environmental pressures have conferred species specific behavioral and morphological traits to optimize reproductive success. To optimally interact with their environment, nervous systems have evolved motor-to-sensory circuits that mediate the processing of its own reafference. Moth flight behavioral patterns to odor sources are stereotyped, presumably to optimize the likelihood of interacting with the odor source. In the moth Manduca sexta wing beating causes oscillatory flow of air over the antenna; because of this, odorant-antennal interactions are oscillatory in nature. Electroantennogram recordings on antennae show that the biophysical properties of their spiking activity can effectively track odors presented at the wing beat …

The Effects Of Instructor Self-Disclosure On Students’ Cognitive Learning: A Live Lecture Experiment, Stephen Michael Kromka

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to examine the causal influences of relevant (and irrelevant) instructor self-disclosure on student affect and cognitive learning. Relevant self-disclosure involves the instructor directly relating personal disclosures to important lesson content, whereas irrelevant self-disclosure involves the instructor’s personal disclosures straying from the lesson topic. Given previous correlational self-disclosure research, the researcher predicted that relevant (compared to irrelevant) instructor self-disclosure would lead to increased reports of affect toward the instructor. The researcher also predicted that instructor self-disclosure relevance (compared to irrelevance) would enhance lesson coherence, and in turn, foster students’ cognitive learning. The researcher conducted a …

Interpretations Of Bicoherence In Space & Lab Plasma Dynamics, Gregory Allen Riggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

The application of bicoherence analysis to plasma research, particularly in non-linear, coupled-wave regimes, has thus far been significantly belied by poor resolution in time, and/or outright destruction of frequency information. Though the typical power spectrum cloaks the phase-coherency between frequencies, Fourier transforms of higher-order convolutions provide an n-dimensional spectrum which is adept at elucidating n-wave phase coherence. As such, this investigation focuses on the utility of the normalized bispectrum for detection of wave-wave coupling in general, with emphasis on distinct implications within the scope of non-linear plasma physics. Interpretations of bicoherent features are given for time series from …

Neuroimaging Of Real-World Audio-Visual Sensory Integration In High-Functioning Autism, Paula J. Webster

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sensory processing differences are a prevalent aspect of autism spectrum disorder (ASD) that may contribute to core deficits of ASD such as repetitive behaviors as well as comorbidities including anxiety disorders. The ability to integrate information among our senses is required to comprehend the world around us and is crucial for the development of language, motor skills, and social communication. Prior studies have shown that individuals with autism differ from individuals without autism when presented with simple, non-natural audio-visual stimuli such as basic shapes accompanied by pure tones. Because the human brain processes non-natural and natural stimuli differently, more recent …

State Counter-Insurgency And Political Policing In Colonial And Post-Colonial Malawi, 1891-1994, Paul Brenard Chiudza Banda

Graduate Theses, Dissertations, and Problem Reports (ETD)

This is a study that adopts the longue durée historical approach to analyze the main causes behind the rise of ‘insurgencies’ or the so-called resistance against the colonial and post-colonial state in the present-day southern African country called Malawi from 1891 to 1994. In turn, it also uses the concept of ‘counter-insurgency’ to analyze the various measures the states in question used to defeat the ‘insurgents’. To arrive at the conclusions made in the study, I have migrated through various domestic and transnational spaces, personalities, and documents that inform the current study. I also adopt two main historical approaches to …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This data-driven journalism project tackles an age-old problem that seems common in virtually every government around the world: governmental officials hiding assets. By applying the theory of social responsibility, this paper uses data-journalism methods to trace the full financial assets of Armenian members of parliament and eventually making those assets and income declarations available via an interactive website to the Armenian public as well as other journalists throughout the country and region.

Prizes, Winning, And Identity: Narrative Vocal Music Of The Pulitzer Prize, 2008–2018, Julia K. Kuhlman

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis considers the ways in which the Pulitzer Prize for Music shapes and is shaped by music of the moment. Since 1943, the Pulitzer Prize has marked 83 pieces as “distinguished” examples of American music. The financial rewarding of winning composers and the initiation of a reciprocal transfer of prestige and political capital, the Pulitzer’s expert juries and governing body has contributed to the preservation of a perpetually-shifting status quo. By chronicling the year-to-year shifts of administrative power dynamics in prize selections, the Pulitzer Prize has mirrored the changing American musical landscape.

Drawing on methods of reception history, archival …

Mandarin -Guo Under Control: An Experimental Study, Wei Zhou

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the experiential aspectual marker -guo under control in Mandarin. The status of -guo under control has been a subject of controversy, involving two important theoretical questions. The first question concerns whether -guo under control is syntactically associated with the matrix verb or the embedded verb. The second question deals with whether, in terms of interpretive effects, -guo under control triggers actuality entailments. This thesis addresses the latter question through an interpretive judgment test conducted among 260 native Mandarin speakers. In the test, three control verbs (changshi ‘try’, guli ‘encourage’, and zuzhi ‘oppose’) were selected, each of …

The purpose of this phenomenological study is to capture and understand the perceptions and experiences of community members who participated in a two-year service-learning project, with the goal of sharing lessons to improve university-community engagement relationships and practices. A qualitative phenomenology approach, using semi-structured interviews, was the method used …

Adoption And Impact Of Telemental Health On Healthcare Outcomes In The United States, Xiaohui Zhao

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mental health conditions (MHCs) are the most expensive conditions in the United States (US). The high MHC prevalence coupled with continued undertreatment of MHC has contributed significantly to this high economic burden. Despite policy changes to increase mental health parity and integrate mental and physical healthcare, the shortage of mental health providers remains a significant barrier to mental health (MH) treatment. Telemental health (TMH) has emerged as an alternative care delivery approach to meet the growing demand of MH care and shortages of MH providers. Understanding the adoption of TMH among mental health facilities is critical for informing the broad …
