Development Of An Effect Size To Classify The Magnitude Of Dif In Dichotomous And Polytomous Items, James D. Weese

Graduate Theses and Dissertations

A standardized effect size for the SIBTEST/POLYSIBTEST procedure is proposed, allowing for Differential Item Functioning (DIF) to be classified with a single set of DIF heuristics regardless of whether data are dichotomous or polytomous. This proposed standardized effect size accounts for both variability in responses and whether participants are included in the SIBTEST/POLYSIBTEST calculations. First, a new set of unstandardized effect size heuristics are established for dichotomous data that are more aligned with Educational Testing Service (ETS) standards using two and three parameter logistic (2PL and 3PL) models. Second, a standardized effect size is proposed and compared to other DIF …

Exploring Sediment Compaction In Experimental Deltas: Towards A Meso-Scale Understanding Of Coastal Subsidence Patterns, Samuel Mason Zapp

Graduate Theses and Dissertations

Subsidence in low elevation coastal areas has been extensively researched through direct field measurement, numerical modelling, and stratigraphic reconstruction of ancient sediment deposits. Here I present the first investigation of subsidence due to sediment compaction and consolidation in two laboratory scale river delta experiments. Compactional subsidence rates have never been thoroughly quantified in the experimental setting, though this mechanism is found to be a primary creator of total relative sea level rise which will likely cause coastlines to retreat in the coming years. Spatial and temporal trends in subsidence rates in the experimental setting may elucidate behavior which cannot be …

Developing A Medium-Voltage Three-Phase Current Compensator Using Modular Switching Positions, Vinson Jones

Graduate Theses and Dissertations

The objective of this thesis is to present the context, application, theory, design, construction, and testing of a proposed solution to unbalanced current loading on three-phase four-wire systems. This solution, known as the Medium-Voltage Unbalanced Current Static Compensator or MV-UCSC, is designed to recirculate currents between the three phases of adistribution system. Through this redistribution of the currents negative- and zero-sequence current components are eliminated and a balanced load is seen upstream from the point of installation. The MV-UCSC as it operates in the distribution system is presented followed by its effect on traditional compensation equipment. The construction of the …

Functional And Physiological Role Of Extra-Hypothalamic Corticotropin Releasing Hormone Neurons In The Nucleus Of The Hippocampal Commissure In Regulation Of Stress Response, Hakeem Kadhim

Graduate Theses and Dissertations

Corticotropin releasing hormone (CRH) neurons located within the paraventricular nucleus (PVN) are known to be involved in regulation of stress responses. Recently, CRH neurons were identified above the PVN within the nucleus of the hippocampal commissure (NHpC) that located in the septum. We hypothesized that CRH neurons in the NHpC play a critical role in the stress response due to their rapid activation and could be a part of the traditional hypothalamo-pituitary-adrenal (HPA) axis. The dissertation addresses the role of 1) CRH expressing neurons in the NHpC compared with those within the PVN utilizing two different stressors, food deprivation (FD) …

Assimilating Through Consumption: A Rhetorical History Of The Early Years Of The Advocate, Cora Beth Butcher-Spellman

Graduate Theses and Dissertations

This thesis uses analysis of constitutive rhetoric and queer archival methods to examines how The Advocate used assimilationist rhetoric and consumerist rhetoric in fundamentally anti-democratic ways to consolidate the form of ideal gay consumer-citizenship. Focusing on the first three years of the publication, I utilize queer theory and theories of citizenship and political economy to explain how The Advocate’s rhetoric and mainstream success allowed the publication to normalize a limited and politically weak gay identity. This thesis argues The Advocate’s rhetoric of exclusion, authority, and consumerism were three central features shaping ideal gay consumer-citizenship as most available to people who …

More Than Just A Tie: The Role Of Content And Context In Firm Alliance Networks, Holly Loncarich

Graduate Theses and Dissertations

Researchers often rely on social network theory to understand both the structural antecedents and outcomes of strategic alliances. However, many alliance studies only emphasize the existence of a tie and rarely theorize further about their efficacy. This failure to consider the role and variation of content in alliance ties (e.g. resource commitment, trust, information exchange) may hinder the application of various network theories at the interorganizational level. Further, interorganizational network studies have largely neglected the role of the external environment, or context, in interfirm collaboration and often fail to consider how the external environment shapes firm network actions and outcomes. …

From The Womb To The Word: Pregnancy And Pregnancy Metaphors In 16th And 17th Century English Literature, Kelly S. Westeen

Graduate Theses and Dissertations

This dissertation employs a feminist theoretical lens in exploring the gendered uses of pregnancy and pregnancy metaphors in the production and dissemination of literary works in early modern England. By also examining the history of the printing press and the role it played in gendered textual production, early modern constructs of family and the role of mothers, as well as obstetric medicine and childbirth, I aim to demonstrate that mothering and authorship were congruent activities for female writers. Conversely, I argue that male writers of the period who employed metaphors of gestation did so not to try to claim biological …
