Eyes In The Field, A Seat At The Table, A Voice At The Ranch : A Study On Optimal Farm Labor Conditions., Christine Wiggins-Romesburg
Electronic Theses and Dissertations
The field of human resource development has twin obligations to promote the performance of organizations and the satisfaction and welfare of all workers. Nevertheless, agriculture appears to be an understudied industry in the field, despite this obligation and the potential for suffering experienced by workers performing crop work. This case study sought to understand the process through which a single agricultural operation fosters optimal conditions for workers engaged in labor-intensive crop production. This study found employees experienced better treatment compared to other agricultural operations, and that conditions were rich in both intrinsic and extrinsic factors. Intrinsic factors were marked by …
Vile Transgressor Of The Womb : Prosecution And Persecution For Concealment In Puritan Massachusetts., Jennifer White
Vile Transgressor Of The Womb : Prosecution And Persecution For Concealment In Puritan Massachusetts., Jennifer White
Electronic Theses and Dissertations
This dissertation investigates the crime of concealment in Puritan Massachusetts. The 1624 Jacobean statute, which specifically identified concealing as both the crime and the evidence, provided the basis for prosecuting women who concealed the death of an infant. This dissertation focuses on an analysis that connects the act of concealment to a larger discussion of a woman’s association with secrecy and hiding that led to labeling her postpartum, criminal body as a threat to the colony. The act of concealment was evidence of a woman’s ability to control her own reproduction and her unwillingness to acknowledge her calling in Puritan …
(Un)Bound : Disrupting Notions., Reid Broadstreet
(Un)Bound : Disrupting Notions., Reid Broadstreet
Electronic Theses and Dissertations
(un) bound: disrupting notions is a selection of art work that explores gender identity through the act of interpellation and the semiotics of clothing. The project aims to clearly define how concepts of “gender” and “sex” function in our language and, in turn, how the binary terms of these concepts (man/woman; male/female) enforce our genders rather than express them. Clothing is a particularly productive form for this investigation because clothing is often the way we express our gender, and yet it is also often produced for us along strict, socially-prescribed gender lines. Typically, conversations around gender are very black …

Nanowire Based Adsorbents/Catalysts For Co2 Capture And Utilization., Apolo Nambo
Electronic Theses and Dissertations
Even today, the major energy source is fossil fuels, which release CO2, a greenhouse gas that contributes to global warming. CO2 capture, storage (CCS) and/or utilization (CCU) technologies are two routes to mitigate this problem. Sorbents are being investigated in either temperature swing or pressure swing absorption approaches for carbon capture from flue gases. Solid sorbent based technology is a promising one but suffers from slow kinetics, low capacity and need for high temperatures. Thus, new sorbent materials that can have good CO2 sorption capacity, recyclability are sought. Similarly, one of the utilization approaches for CO …
Plasma-Assisted Liquid Phase Epitaxy Of Gallium Nitride Using Molten Gallium., Daniel Felipe Jaramillo-Cabanzo
Plasma-Assisted Liquid Phase Epitaxy Of Gallium Nitride Using Molten Gallium., Daniel Felipe Jaramillo-Cabanzo
Electronic Theses and Dissertations
Next generation semiconductor materials such as Gallium Nitride (GaN) and Silicon Carbide (SiC) are rapidly replacing Silicon (Si) for high power and high frequency applications due to Si’s inherent limitations. Despite the advantages of GaN over SiC, adoption of GaN has been hindered due to the lack of a cost-effective bulk production technique. Thus, the inability to precure native substrates requires GaN-based architectures to be heteroepitaxially synthesized on non-native substrates, such as sapphire and even SiC. This research seeks to develop a cost effective and scalable method to produce low defect, bulk GaN encouraging the adoption of GaN based devices …

Use Of Anodic Stripping Voltammetry To Study The Size-Selective Electrophoretic Deposition And Aggregation-Dependent Oxidation Of Metal Nanoparticles., Stacy L. Allen
Electronic Theses and Dissertations
This dissertation describes how anodic stripping voltammetry (ASV) was used to study size-controlled electrophoretic deposition (EPD) and the aggregation-dependent oxidation properties of citrate-stabilized Au nanoparticles (NPs). EPD of citrate-coated Au NPs occurs in the presence of hydroquinone (HQ) onto indium-tin-oxide-coated glass electrodes (glass/ITO) at potentials positive of the HQ oxidation potential. HQ oxidation produces protons at the electrode surface, which serve to neutralize the citrate molecules that electrostatically stabilize the Au NPs. Neutralization leads to the loss of stabilization and deposition onto the electrode. EPD in the presence of ferrocyanide, a non-proton-producing molecule, at oxidation potentials resulted in no deposition …
Reading The Readers : Analyses Of Shakespearean And Cervantine Characters As (Dys)Functional Readers., Erin Shannon O'Reilly
Reading The Readers : Analyses Of Shakespearean And Cervantine Characters As (Dys)Functional Readers., Erin Shannon O'Reilly
Electronic Theses and Dissertations
This dissertation analyzes how the protagonists of Don Quixote and The Tempest perform the act of reading. It explores how the authors create interpretive communities within their works and bring them into conflict in order to foreground the dysfunctionality of particular types of reading. While functional readers are capable of reading among and beyond diverse interpretive communities, dysfunctional readers operate within a single community to the exclusion of other possible interpretations. Chapter One examines Cervantes’s creation of multiple interpretive communities within the first six chapters of Don Quixote, and how Don Quixote acts as dysfunctional reader through his inability …
Developmental Changes In Reasoning About Cross-Classified Individuals., Catherine H. Mcdermott
Developmental Changes In Reasoning About Cross-Classified Individuals., Catherine H. Mcdermott
Electronic Theses and Dissertations
Social categories allow children to make inferences about novel situations, which can then guide their interactions with others. However, this process can be complicated because individuals often belong to many different, sometimes interrelated, social categories. Four experiments examine whether children and adults differ in their willingness to classify a person as holding two social roles (e.g., a mother and a daughter), and how this influences their reasoning. Specifically, this work will examine the influence of cross-classification on inductive inferences, trust in testimony, and knowledge evaluations. The aim of these experiments is to investigate whether children privilege certain roles when reasoning …

Electronic Theses and Dissertations
Thalidomide analogues were synthesized utilizing optimized click conditions from 3-azidoglutarimide and an array of arylacetylenes or N-ethynyl/N-propargyl phthalimide derivatives. The intermediate, 3-azidoglutarimde, was pivotal and yielded a new and scalable synthesis. The reaction conditions utilized a copper sulfate/sodium ascorbate system in aqueous tetrahydrofuran to propagate the dipolar cycloaddition reactions between the azidoglutarimide and the alkynyl coupling partners. The first explored substrates were substituted arylalkynes to optimize the click reaction. Arylalkynes selected were to exhibit similar electron deficient rings to mimic phthalimide. Along with the synthesis of click thalidomide analogues, click analogue of the antiangiogenic and more potent …

An Explainable Sequence-Based Deep Learning Predictor With Applications To Song Recommendation And Text Classification., Khalil Damak
Electronic Theses and Dissertations
Streaming applications are now the predominant tools for listening to music. What makes the success of such software is the availability of songs and especially their ability to provide users with relevant personalized recommendations. State of the art music recommender systems mainly rely on either Matrix factorization-based collaborative filtering approaches or deep learning architectures. Deep learning models usually use metadata for content-based filtering or predict the next user interaction (listening to a song) using a memory-based deep learning structure that learns from temporal sequences of user actions. Despite advances in deep learning models for song recommendation systems, none has taken …

Anthropogenic Landscapes Of Amazonia : A Spatial Analysis Of Landscape Modification And Settlement Organization At Macurany, Brazil., M. Grace Ellis
Anthropogenic Landscapes Of Amazonia : A Spatial Analysis Of Landscape Modification And Settlement Organization At Macurany, Brazil., M. Grace Ellis
Electronic Theses and Dissertations
Anthropogenic landscapes are the product of complex human-environment processes that form distinct features in the landscape, which materially preserve and reflect human behavior. Anthropogenic landscapes in Amazonia likely date back to human colonization of the region around 16,000 BP. Since colonization, humans have been marking, modifying, managing, and engineering the landscape resulting in a mosaic of anthropogenic landscape features across Amazonia. The diversity of ancient landscapes documented in Amazonia reflects the cultural heterogeneity that existed in the past. This research explores the complex human-environmental processes that form distinct, identifiable, lasting features on the landscape and what these features can illuminate …

Development Of Bar-Peptide Nanoparticles And Electrospun Fibers For The Prevention And Treatment Of Oral Biofilms., Mohamed Yehia Mahmoud
Development Of Bar-Peptide Nanoparticles And Electrospun Fibers For The Prevention And Treatment Of Oral Biofilms., Mohamed Yehia Mahmoud
Electronic Theses and Dissertations
Background: Periodontal diseases are globally prevalent inflammatory disorders that affect ~47% of U.S adults. Porphyromonas gingivalis (Pg) has been identified as a “keystone” pathogen that disrupts host-microbe homeostasis and contributes to the initiation and progression of periodontitis. Pg associates with oral streptococci in supragingival plaque and this interaction represents a potential target for therapeutic intervention. Previously our group developed a peptide (designated BAR), that potently inhibits Pg/Streptococcus gordonii (Sg) adherence in vitro and Pg virulence in a murine model of periodontitis. While efficacious, BAR (SspB Adherence Region) provided transient inhibition and required higher concentrations of BAR to disrupt established …

Kentucky's Superintendent Induction Program : Participants' Perceptions Of Competency And Longevity., Robert L. Smith
Electronic Theses and Dissertations
The position of the school superintendent in the United States, at both the state and local level, has evolved over the past 200 years in response to the needs of the profession, ever-changing communities, and political mandates (Kowalski et al., 2011). The role of superintendent has shifted in focus from teacher-scholar to manager to democratic leader to social scientist and, finally, to communicator (Callahan, 1966; Bjork, Browne-Ferrigno, & Kowalski, 2018). Generalizing the problems facing superintendents can be a challenging proposition. However, no two situations are the same. A number of factors, including school board size, district demographics, financial position, state …

"Gentlemen With Brains" : The Use Of Historical Figures In The Development Of The Character Of Hortensio In An Adaptation Of William Shakespeare's The Taming Of The Shrew., Terry Tocantins
Electronic Theses and Dissertations
In 2018, I played Hortensio in a production of The Taming of the Shrew that took place among the businessmen in the America of 1963. This thesis centers on the strategies and tactics I employed in the portrayal of Hortensio, a moneyed, middle aged, single man who impersonates a music tutor to seduce the much younger Bianca. In my research I investigated the archetype of the advertising executive of the era. The world views of these men upheld the post-war conception of American exceptionalism, and in their occupations were adept at manipulation free of the fear of consequences. Hortensio is …
Preference For Odor-Taste Mixtures Is Dependent On Previous Experience., Kelsey Allison Mcqueen
Preference For Odor-Taste Mixtures Is Dependent On Previous Experience., Kelsey Allison Mcqueen
Electronic Theses and Dissertations
The perception of flavors occurs when a tastant is simultaneously detected and associated with an odorant (i.e., odor-taste mixture). Sampling an odor and taste together results in a congruent odor-taste mixture. Mixing an odor and taste from different congruent odor-taste pairs results in incongruent odor-taste mixtures. Creation of a flavor percept requires sampling a novel chemosensory stimulus; however, mammals exhibit robust neophobic behavior when presented with new chemosensory stimuli. To determine preferences for novel odorants and experienced odor-taste mixtures, we employ a two-bottle brief-access preference task where two chemosensory stimuli are presented simultaneously. We found that rats show a preference …
