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 …

New York Sons Of Erin: Nativism, Identity, And The Importance Of Irish Ethnicity In The Civil War Era, Abbi E. Smithmyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nineteenth-century Irish Americans were bound together by a shared ethnic identity that was shaped by a strong attachment to Ireland, a closeness enhanced by their devotion to the Catholic faith, and an American population that held a deep prejudice against the ethnic group. This was especially the case in New York, which had the largest population of Irish Americans in the United States during this time. While many Sons of Erin enlisted into New York regiments, their most famous unit was the Irish Brigade. Therefore, the actions and treatment of the Irish Brigade greatly influenced the way immigrant service in …

Gendered Access To Wetland Gardens (Dimba) In Northern Malawi, Rhoda Nyirenda

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to increasing degradation of upland fields and in the face of erratic rains and increasing occurrence of droughts and floods and increasing food prices, smallholder farmers in many places across sub Saharan Africa engage in wetland cultivation for livelihoods security (Mutambikwa et al., 2000). A cultivatable wetland area is considered prime land, and a desired opportunity that every rural family need for the purpose of food production. Studies have indicated that wetland cultivation significantly contributes to household’s income and food security. Wetland agriculture, however, in Malawi and most of the sub-Saharan African countries is marred with issues of access …

On Body Mass Index Analysis From Human Visual Appearance, Min Jiang

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past few decades, overweight and obesity are spreading widely like an epidemic. Generally, a person is considered overweight by body mass index (BMI). In addition to a body fat measurement, BMI is also a risk factor for many diseases, such as cardiovascular diseases, cancers and diabetes, etc. Therefore, BMI is important for personal health monitoring and medical research. Currently, BMI is measured in person with special devices. It is an urgent demand to explore conveniently preventive tools. This work investigates the feasibility of analyzing BMI from human visual appearances, including 2-dimensional (2D)/3-dimensional (3D) body and face data.

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 …

Utilizing Conservation Genetics As A Strategy For Recovering The Endangered Candy Darter (Etheostoma Osburni) In West Virginia, Brin E. Kessinger

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Candy Darter (Etheostoma osburni) is a small freshwater fish native to the New River drainage in West Virginia and Virginia that was listed as endangered in November 2018. It has been extirpated from much of its historic range in West Virginia, restricting it to the Gauley and Greenbrier river drainages. In addition to extirpations, the species is threatened by introgressive hybridization with the invasive Variegate Darter (E. variatum). Previous research primarily focused on hybridization, but population genetic analyses were limited. Population genetic analyses aim to identify distinct populations through genetic structure and characterize the levels …

Automated And Standardized Tools For Realistic, Generic Musculoskeletal Model Development, Trevor Rees Moon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Human movement is an instinctive yet challenging task that involves complex interactions between the neuromusculoskeletal system and its interaction with the surrounding environment. One key obstacle in the understanding of human locomotion is the availability and validity of experimental data or computational models. Corresponding measurements describing the relationships of the nervous and musculoskeletal systems and their dynamics are highly variable. Likewise, computational models and musculoskeletal models in particular are vitally dependent on these measurements to define model behavior and mechanics. These measurements are often sparse and disparate due to unsystematic data collection containing variable methodologies and reporting conventions. To date, …

Dissimilar Phonemes Create A Contextual Interference Effect During A Nonword Repetition Task, Kimberly Michelle Meigh, Elisabeth Kee

Faculty & Staff Scholarship

Purpose: The contextual interference effect is a motor learning phenomenon where conditions that decrease overall learning during practice enhance overall learning with new tasks. In the limb literature, this effect is observed when different practice conditions are used (e.g., blocked vs. random practice schedules). In speech motor learning, contextual interference effects are mixed. The differences observed during speech motor learning may be due to the stimuli used. We hypothesized that dissimilar phonemes might create interference during speech motor learning, such that training accuracy would decrease. However, generalization accuracy would increase compared to practice with nonwords containing similar phonemes.

Rivers transport sediments in a source to sink system while responding to allogenic controls of the depositional system. Stacked fluvial sandstones of the Middle Pennsylvanian (Desmoinesian Stage, ∼310–306 Ma) Allegheny Formation (MPAF) exposed at Birch River, West Virginia exhibit change in sedimentary structure and depositional style, reflecting changes in allogenic behavior. Paleohydrologic and numerical analysis were used to quantify geomorphological and paleohydrologic variations reflected by MPAF fluvial deposits with the goal of understanding the controls on resulting fluvial sandstone architecture in these different systems. Channel body geometry, sedimentary structures, and sandstone grain size distribution were used to reconstruct the paleoslope …

Breastfeeding Duration Is Associated With Regional, But Not Global, Differences In White Matter Tracts, Christopher E. Bauer, James W. Lewis, Julie Julie Brefczynski-Lewis, Chris Frum, Margeaux M. Schade, Marc W. Haut, Hawley E. Montgomery-Downs

Faculty & Staff Scholarship

Extended breastfeeding through infancy confers benefits on neurocognitive performance and intelligence tests, though few have examined the biological basis of these effects. To investigate correlations with breastfeeding, we examined the major white matter tracts in 4–8 year-old children using diffusion tensor imaging and volumetric measurements of the corpus callosum. We found a significant correlation between the duration of infant breastfeeding and fractional anisotropy scores in left-lateralized white matter tracts, including the left superior longitudinal fasciculus and left angular bundle, which is indicative of greater intrahemispheric connectivity. However, in contrast to expectations from earlier studies, no correlations were observed with corpus …
