Considering Contextual Factors In The Perception And Attribution Of Racial Microaggressions, Roselee Ledesma
Considering Contextual Factors In The Perception And Attribution Of Racial Microaggressions, Roselee Ledesma
Graduate Theses and Dissertations
Black, Indigenous, People of Color (BIPOC) experience interactions with subtle or ambiguous racial undertones that may be perceived as discriminatory, benign, or even complimentary. These interactions have been labeled microaggressions or a subtle form of everyday discrimination. Microaggressions are associated with detrimental health and cognitive effects (Lui & Quezada, 2019; Ozier et al., 2019). To better understand and label microaggressions, it is important to consider contextual factors. For example, the same statement or behavior is likely interpreted differently depending on who is involved, what is said or done, when it occurs, where it takes place, and why the statement or …

Decrypting The Processes Of Policy Evolution: Comparing Québec And Ontario’S Evolution Of Risk Management Policies, Frederick Clerson Guicherd
Graduate Theses and Dissertations
Through policies or programs, states can influence industries to align with their vision of what a sector should become. However, this vision is subject to influence from actors of the industries which emphasize the importance of the relationship between the state and interest groups. In this dissertation, we observe the evolution of 9 Canadian agriculture risk management programs implemented by two provincial governments between 1990 and 2020 to understand how such programs coped with the new trends in agriculture. Through a review of parliamentary discussions and official documents, we evaluate the factors that justified program evolution based on the combination …

Treating High Salinity Produced Water Using Hybrid Membrane Processes: Electrocoagulation-Microfiltration/Ultrafiltration-Membrane Distillation-Crystallization, Mahmood Gheni Jebur
Graduate Theses and Dissertations
Produced water (PW) is considered the largest industrial wastewater stream in the world. PW generated from oil and gas operations generally contains a range of contaminants including high total dissolved solids, high total suspended solids, polar and nonpolar organic compounds, and low surface tension dissolved species. Treating PW is very challenging and applying only membrane-based technologies is not sufficient due to membrane fouling, which affects their long-term performance. Hence, integrated membrane processes are required to treat PW effectively. Hybrid membrane processes, which may result from combining a conventional process with a membrane separation, could be used to address the issues …
The Effect Of Sleep Deprivation On The Ability To Reappraise Negative Situations, Rebecca Campbell
The Effect Of Sleep Deprivation On The Ability To Reappraise Negative Situations, Rebecca Campbell
Graduate Theses and Dissertations
Sleep and emotion regulation are important components of mental health and may function interdependently in the development and maintenance of mental health disorders. Unfortunately, there is limited experimental work on the impacts of sleep deprivation on reappraisal, a common emotion regulation strategy, in adults. Furthermore, increases in negative and decreases in positive affect are often associated with sleep loss. This study aimed to examine the relation between sleep deprivation and emotion regulation by asking adults to reappraise a series of vignettes before and after a randomly assigned night of sleep deprivation or normal sleep. Additionally, measures of self-reported emotion regulation …

Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Use Of Microorganisms For The Enrichment Of Zn And Se By Using Solid-State Fermentation, Rashmi Rangaswamaiah
Graduate Theses and Dissertations
Zinc (Zn) and selenium (Se) are essential minerals for human health and naturally found in many food sources. However, the risk of Zn and Se deficiency has been recognized in several countries. As most people throughout the world consume rice, grains, and cereals as staple foods in their daily diet, which contain a certain amount of phytic acid (antinutrients), the phytic acid content inhibits mineral absorption (Zn and Se) by the human body. Moreover, the low levels of Zn and Se content found in the crop's soil also reduce the amount of minerals in the food sources. Therefore, it is …

Improving Tribological Properties Of Polydopamine/Polytetrafluoroethylene Coatings Through Incorporating Core-Shell Nanoparticles And Laser Surface Texturing, Firuze Soltani-Kordshuli
Improving Tribological Properties Of Polydopamine/Polytetrafluoroethylene Coatings Through Incorporating Core-Shell Nanoparticles And Laser Surface Texturing, Firuze Soltani-Kordshuli
Graduate Theses and Dissertations
Polytetrafluoroethylene (PTFE) is a widely used polymer that has unique properties such as chemical and temperature resistance, corrosion resistance, low maintenance cost, and a very low coefficient of friction (COF). These distinctive properties have made PTFE a promising candidate for industrial applications where surfaces are in relative motion. PTFE can be utilized as a thin film solid lubricant to significantly reduce the friction between moving surfaces. However, PTFE coatings have low cohesion and poor adhesion to the substrate resulting in its low wear resistance. This fact limits the application of PTFE coatings in load-bearing situations. To address these limitations, an …

Bond-Breaker Properties Of Different Media For Concrete Pavement Design, Andres Calzacorta
Bond-Breaker Properties Of Different Media For Concrete Pavement Design, Andres Calzacorta
Graduate Theses and Dissertations
Currently Arkansas requires a layer of asphalt as the main bond-breaker over cement treated base for rigid pavement design. The study presented in this paper aims to replicate the results from previous research which demonstrated the bond-breaker properties of concrete curing compounds and geotextiles. Bond-breakers are materials applied to the surface of stabilized bases to reduce the interaction between the base and a pavement cement concrete layer. The excessive interaction between these two layers can lead to cracking in the overlay and reduction of the serviceability life of concrete. The curing compound was applied in a single application (SA, 200 …

Dpd Guided Insight On The Formation Process Of Polyethersulfone Membranes By Nonsolvent Induced Phase Separation And The Effects Of Additives, Eric Ledieu
Graduate Theses and Dissertations
Dissipative particle dynamics (DPD), a coarse grain simulation method, was applied to the membrane formation process of non-solvent induced phase separation (NIPS) to gain further insight on the mechanism of certain variables and how they affect the final morphology. NIPS involves two solutions, an organic polymer dissolved in an organic solvent colloquially called the dope and an aqueous coagulation bath, brought into contact with one another. The solvents then mix, causing the polymer to fall out of solution as an asymmetric membrane with a dense surface layer and a more open subsurface layer in response to the decreasing solubility. Polyethersulfone …
The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage
The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage
Graduate Theses and Dissertations
Over several decades, a greater share of the expense of earning a college degree has shifted to students and their families as appropriations to public institutions of higher education have declined as a percentage of the overall cost to educate a student. Tuition has greatly outpaced inflation during this period, while inflation-adjusted household income has remained relatively flat. Despite all the benefits that accrue to both the college graduate and society as a whole, for the less affluent, a college education is becoming increasingly difficult to attain. Many decide the financial barriers are simply too great and elect not to …

The Autistic Perspective: Interviewing Autistic Adults On Lived Experiences With Behavior Modification And How It Has Shaped Their Communication, Lighla R. Whitson
Graduate Theses and Dissertations
The use of behavior modification (BM) based treatment, the best-known example being Applied Behavior Analysis (ABA), is established as an evidence-based practice for promoting communication and other outcomes for Autistic individuals. As such, many Speech Language Pathologists (SLPs) use it in their practice to target various forms of communication. Among many autistic advocacy groups, however, ABA and other BM informed therapies are often described as a detriment to mental and emotional health. Organizations such as the Autistic Self Advocacy Network (ASAN) have come out against the practices and recommend finding different approaches to teaching communication skills. Much research is needed …
Automation Of Life Cycle Assessment, Jacob Hickman
Automation Of Life Cycle Assessment, Jacob Hickman
Graduate Theses and Dissertations
An automation program, named Jacob LCA, was created to help perform life cycle assessment (LCA). The program uses a template file to perform controlled and consistently ordered actions with the LCA program, SimaPro, and effectively removes the need for manual user input. It can be set to run using data from one or more life cycle inventory (LCI) files, which allows for rapid iteration and testing of data. It also partially addresses some of the limitations of LCA by establishing a procedure through which temporal and spatial variations in data can be integrated into LCI files and then passed to …

Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance
Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance
Graduate Theses and Dissertations
Previous research suggests that highlighting the gap between inconsistent values can result in long-term attitude change (Rokeach, 1971), that feeling hypocritical might prompt pro-attitudinal behavior (e.g., Dickerson et al., 1992), and that a reactance decoy makes participants more receptive to subsequent persuasive messages (Schumpe et al., 2020). Drawing from these findings, the purpose of the present study was to investigate whether the impact of induced hypocrisy on pro-life abortion attitudes, an attitude commonly grounded in the value of freedom, depended on a reactance decoy. Consistent with Aronson et al.’s paradigm (1991), participants first publicly advocated for the importance of personal …

A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira
Graduate Theses and Dissertations
According to the American Immigration Council (2021), 14 percent of the United States population is foreign-born. Immigrants have enriched American culture and enhanced our influence in the world. People feel a need to belong and have an inherent desire for deep, lasting, and meaningful connections (Baumeister & Leary, 1995). Research suggests that humans are fundamentally and pervasively motivated by a need to belong and the desire to form and maintain enduring interpersonal attachments (Allen, Kern, Rozek, McInerney & George, 2021). These authors also define immigrants’ sense of belonging in terms of how they make sense of their social identification with …

Mitral Valve Imaging And Biomechanics: A Workflow Towards Computational Modeling And Validation, Sam Stephens
Mitral Valve Imaging And Biomechanics: A Workflow Towards Computational Modeling And Validation, Sam Stephens
Graduate Theses and Dissertations
The mitral valve serves a critical role in healthy cardiac function by ensuring the unidirectional flow of oxygenated blood from the left atrium into the left ventricle. It experiences the highest pressures found within the heart and its closure is the result of a complex interaction of several different structures that, furthermore, are unique to each individual. Despite the valve’s vital role however, the specific function of these constituent structures is not fully understood. This, confounded by its asymmetric, personalized nature, make surgical interventions for the mitral valve far less effective than for its neighboring aortic valve. Efforts to overcome …
(Nearly) All Roads Lead To Polarization: Cognitive Dissonance And The Inverse Relationship Between Polarization And Trivialization In The 2016 And 2020 Elections, Austin D. Eubanks
(Nearly) All Roads Lead To Polarization: Cognitive Dissonance And The Inverse Relationship Between Polarization And Trivialization In The 2016 And 2020 Elections, Austin D. Eubanks
Graduate Theses and Dissertations
The present study investigated cognitive dissonance theory—in particular, outcome-based dissonance, i.e., dissonance experienced from facing an outcome inconsistent with ones’ choice (in this case, preferring the candidate who lost the election)—in electoral contexts using the 2016 and 2020 American National Election Studies data (ns = 3,648 and 7,453, respectively). The particularly negative context of the 2016 and 2020 elections offered an opportunity to make a novel direct empirical comparison of choice valence between “hard/positive choices” (i.e., between two “good” alternatives) and “hard/negative choices” (i.e., between two “bad” alternatives) using real-world data. Results showed that after the election, respondents who preferred …
