Distributed Agency And Posthuman Rhetoric In Genai-Assisted First-Year Composition Writing, Bianca E. Guzman
Distributed Agency And Posthuman Rhetoric In Genai-Assisted First-Year Composition Writing, Bianca E. Guzman
English Department Theses
This thesis explores the dynamic interaction between human and non-human agents in the process and production of writing. In particular, theories on the co-constitutive nature of the human-technological relationship, posthumanist theory, and rhetorical theory are used to reframe first-year writing as an act of distributive agency that always involves people, objects, and their material environments. In recognizing the essential role of “things” in first-year writing, this thesis considers how Generative Artificial Intelligence (GenAI) can be critically conceptualized and utilized as a pedagogical tool by instructors in the college writing classroom. Additionally, this thesis details an IRB-approved research study done at …

An Analysis Of Portuguese Colonial Representations Of Sinhalese Women, Chandra R. De Silva, Ramani Hettiarchchi
History Faculty Publications
The history of Sri Lanka until recently has been written mostly as the history of men in the country. This has been particularly true of the early modern period, for which existing records are mostly those of visiting colonizers who were mostly men, writing about their dealings with those in power or with those from whom they could gain profit. This article is an attempt to collect and analyze the admittedly limited data on how the Portuguese who gained political authority over parts of the coastal areas saw local women. It is limited to the women of the majority community …
How Presidents Shift Ideological Stances In Legislative Elections: Evidence From South Korean Presidential Speeches, Doyeon Park
How Presidents Shift Ideological Stances In Legislative Elections: Evidence From South Korean Presidential Speeches, Doyeon Park
Department of Political Science: Dissertations, Theses, and Student Research
Presidents have a strong desire to lead their parties to victory in elections. However, relatively little attention has been paid to their ideological stances in legislative elections. This contrasts with extensive research on the ideological strategies of parties and candidates who directly compete for office. How do presidents adjust their ideological positions in legislative elections? This study examines the institutional dynamics surrounding presidents, focusing on their dual responsibilities and the role of legislative elections as a referendum on the presidency. It also considers presidential popularity as a factor that influences these dynamics. I argue that presidents are more likely to …
The Partsongs Of Samuel Coleridge-Taylor, Alan Davis
The Partsongs Of Samuel Coleridge-Taylor, Alan Davis
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
This document examines the complete set of thirteen partsongs by Samuel Coleridge-Taylor (1875-1912) a body of choral works underrepresented in both scholarship and performance. Before the twentieth century, English partsongs had already developed a rich lineage through composers such as Charles Hubert Hastings Parry, Charles Villiers Stanford, Edward Elgar, and Charles Wood. Around 1900, the genre flourished further in the works of Gustav Holst, Ralph Vaughan Williams, Gerald Finzi, and Herbert Howells, whose partsongs were published by Novello & Co. and featured in The Musical Times. Within this broader context, Coleridge-Taylor’s contributions stand apart: his partsongs reveal a distinctive harmonic …

Detecting Prescribed Fire, Haying And Grazing Events Via Remote Sensing To Create Grassland Disturbance Landcovers For The Ring-Necked Pheasant (Phasianus Colchicus), Megan A. Baldissara
Detecting Prescribed Fire, Haying And Grazing Events Via Remote Sensing To Create Grassland Disturbance Landcovers For The Ring-Necked Pheasant (Phasianus Colchicus), Megan A. Baldissara
School of Natural Resources: Dissertations, Theses, and Student Research
This dissertation developed disturbance detection models to fulfill the need for remote sensing landcover products describing grassland structure. The use of landcover products derived from remote sensing is increasing over time in pheasant (Phasianus colchicus) research. Such landcover, however, does not provide relevant pheasant structural habitat information (Chapter 1). Pheasants require tall, high-density grassland for nesting, tall grassland with medium density for brood rearing, and tall grassland for wintering. Time since disturbance can serve as a proxy for structure, as it shapes vegetation by removing biomass and resetting succession. Disturbance is easier to detect than structure with current …
On Bayesian Empirical Likelihood-Based Method For Complex Survey Data With Application To Non-Probability Sampling, Md Hasibur Rahman
On Bayesian Empirical Likelihood-Based Method For Complex Survey Data With Application To Non-Probability Sampling, Md Hasibur Rahman
Department of Statistics: Dissertations, Theses, and Student Research
This thesis develops a Bayesian empirical likelihood (BEL) framework for inference under complex survey designs and extends it to non-probability sampling. Parametric likelihood based methods are difficult to apply to complex survey data because the likelihood is rarely available in closed form. EL provides a flexible alternative by replacing the parametric likelihood with an empirical likelihood constructed from moment conditions. The proposed method first integrates empirical likelihood constraints with survey design features then extends BEL to non-probability sampling through selection models and design consistent restrictions. Posterior inference is carried out using a Metropolis–Hastings MCMC algorithm. A real-data analysis further illustrates …

Modeling The Greenland-Iceland-Faroe Ridge Using Integrated Geophysical Analysis, Zachary Clowdus
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
The Greenland-Iceland-Faroe Ridge (GIFR) is an area of significant geologic interest with anomalously thick crust related to enhanced melt generation from the interaction between the Mid-Atlantic Ridge and the Iceland hotspot. To the northeast of Iceland lies the Jan Mayen Microcontinent (JMMC), which is a continental fragment separated from Greenland during the opening of the Northern Atlantic. The overall extent of the JMMC, especially its southern boundary, remains poorly constrained. The crust beneath the GIFR is believed to be primarily of oceanic affinity. However, a recent discovery of felsic lavas in Iceland led to an alternative hypothesis that implies the …

The Role Of Peroxisomal Acot4 And Acot8 In Modulating Lipid Metabolism And Stress Pathways In Steatotic Hepatocytes, Sylwia Miekus
The Role Of Peroxisomal Acot4 And Acot8 In Modulating Lipid Metabolism And Stress Pathways In Steatotic Hepatocytes, Sylwia Miekus
Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research
Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by excessive lipid accumulation in hepatocytes and the development of lipotoxic stress that disrupts cellular homeostasis. Peroxisomal lipid metabolism plays an important role in maintaining acyl-CoA balance during fatty acid overload, yet the contribution of peroxisomal acyl-CoA thioesterases to early lipotoxic responses remains insufficiently understood. The aim of this study was to investigate the functional involvement of the peroxisomal enzymes acyl-CoA thioesterase 4 (ACOT4) and acyl-CoA thioesterase 8 (ACOT8) in hepatocyte lipid handling under acute lipotoxic conditions. An in vitro model of steatosis was established in AML12 cells through exposure to a …
