Polyamory - The Multiple Complexities Of Multiple Partners, Vianna Isbister

Electronic Theses and Dissertations

This study is an exploration of the relationship between polyamory and how polyamorous people communicate about their relationship dynamics. Drawing from six individual interviews and one focus group, the author compares key language that appears in previous research to the language created by the study participants. Utilizing grounded theory for the analysis, results indicate that the language choices of sexual identity, sexual orientation, and/or relationship model are not sufficient for singularly encompassing a poly experience. Findings indicate that individuals who identify under the umbrella of consensual non-monogamy (CNM) may use the term "polyamory" to describe their own relationship dynamic or …

Cultural Lag Does Not Exist: An Exposition And Critical Evaluation Of W.F. Ogburn’S Hypothesis, Heather L. Osborne

Electronic Theses and Dissertations

Despite a century of scholarly critique, William Fielding Ogburn’s cultural lag hypothesis (CLH) endures. The inclusion of Ogburn’s hypothesis in introductory sociology textbooks, reference books, and histories of technology lends an unwarranted authority to its scientific credibility. I critically assess Ogburn’s CLH and find that it is neither scientifically nor theoretically sound. Specifically, I discover presumptions of cultural integration and normative progressivism, the fallacy of ambiguity, problems of causal explanation, operationalization, and selective bias, which renders the CLH unmeasurable, unfalsifiable, and non-replicable. Finally, I briefly discuss the implications and make suggestions for future research.

Assessing The Applicability Of A Three-Minute All-Out Swimming Test In Collegiate Swimmers, Luis Rodriguez-Castellano

Electronic Theses and Dissertations

Performance tests are used to gauge swimmer fitness and guide training prescription. While some traditional protocols, such as, best average swimming (Bavg) lack scientific support, the three-minute all-out test (3MT) is validated to measure critical speed (CS) and distance capacity above CS (D’) from a single maximal swimming bout. In collegiate swimming, a 3MT could be convenient and time efficient. Yet, issues arise with calculating 3MT parameters. Moreover, anthropometry, resistance training, and stroke technique may influence swimming performance and physiological thresholds including 3MT parameters. Hence, this dissertation focused on evaluating the 3MT parameter calculation methods using the interval and lap …

Cardiovascular Disease In Central Appalachia, An Exploratory Study Of Behavioral, Community, And Patient-Centered Care Influences, Kristy Gagnon

Electronic Theses and Dissertations

The Central Appalachian region of the United States disproportionately experiences higher rates of cardiovascular diseases (CVD) and associated risk factors. Primary risk factors for CVD include hypertension, hypercholesterolemia, and tobacco use, all of which have the potential to be mitigated through lifestyle behavior changes. Dietary and physical activity practices are the two main driving forces for the development of hypertension and hypercholesterolemia, while tobacco use is a behavioral choice on its own. Subsequentially, shifting lifestyle choices to emphasize healthier living has the potential to reduce CVDs within the Central Appalachian region. Considering behavioral choices are not made in isolation and …

A Programmatic Geographic Information Systems Analysis Of Plant Hardiness Zones, Andrew Bowen

Electronic Theses and Dissertations

The Plant Hardiness Zone Map consists of thirteen geographical zones that describe whether a plant can survive based on average annual minimal temperatures. As climate change progresses, minimum temperatures in all regions are expected to change. This work programmatically evaluates predicted future climate projection data and converts it to United States Department of Agriculture-defined hardiness zones. Through the next 80 years, hardiness zones are projected to move poleward; in effect, colder zones will lose area and warmer zones will gain area globally. Some implications include changes in crop growing degree days, which could alter crop productivity, migration and settlement of …

Vibroacoustic Response Of The Tympanic Membrane To Hyoid-Borne Sound Generated During Echolocation In Bats, Chelsie Snipes

Electronic Theses and Dissertations

The hyoid apparatus in laryngeally echolocating bats forms a mechanical connection between the larynx and auditory bullae and has been hypothesized to transfer the outgoing echolocation call to the middle ear during echolocation call emission. We used µCT data to build models of the hyoid apparatus and middle ear from six species of bats and used finite element modeling (FEM) to measure the vibroacoustic response of the tympanic membrane due to hyoid-borne sound generated during echolocation. We found that hyoid-borne sound in all six species stimulated the eardrum within a range likely heard by bats. Although there were minor differences …

Mechanism And Kinetics Of Photocatalytic Partial Oxidation Of Methane On Single Site Mox Reaction Centers., Clint Evrard

Electronic Theses and Dissertations

Single-site transition-metal doped photocatalysts are a class of materials in which small transition-metal oxide clusters are embedded onto the surface of zeolites, graphene, and bulk semiconductors. Experimental findings demonstrate that VO4, CrO4, NbO4, and WO4 clusters embedded on an MCM- 41 mesoporous amorphous SiO2 are effective photocatalysts for oxidative reactions. The selective direct partial oxidation of methane (POM) to form methanol is essential for efficiently utilizing natural gas. Photocatalytic methane oxidation has advantages over traditional thermal catalysis as it can be deployed at small-scale facilities to reduce methane release into the atmosphere due to flaring potentially. Our work has aimed …
