Monitoring Climate Change With Machine Learning And Uncertainty Quantification, Firas Gerges

Dissertations

The impact of climate change on the environment has become increasingly visible today. One important topic in climate change monitoring is to forecast future climate events, which relies on long-term prediction of climate variables at a local regional scale. This topic is crucial for disaster risk management and for resolving climate change at the local level. General Circulation Models (GCMs) allow for the simulation of several climate variables, decades into the future. GCM simulations, however, are at a global large scale and are too coarse to monitor climate change at the local small scale. This dissertation explores new machine learning …

Amphiphilic Block Copolymers And The Applications In Therapeutics Delivery, Jie Dou

Dissertations

Well-defined thermo-responsive triblock copolymers containing polyethylene oxide (PEO) and poly(N-isopropyl acrylamide) PNIPAM are synthesized by a type of living controlled polymerization, named iniferter polymerization. The polymers are amphiphilic in nature and are self-assembled into a micelle. Their properties and application are characterized and investigated in this work.

Biotransformation And Biodefluorination Of Fluorotelomer Carboxylic Acids, Chen Wu

Dissertations

Per- and polyfluoroalkyl substances (PFASs), a class of emerging contaminants of concern, have attacked unprecedented attention given their prevalent detection and adverse health effects. Primary regulatory attention has been focused on PFOA, PFOS, and other perfluoroalkyl acids (PFAAs). Recent investigations revealed that fluorotelomer carboxylic acid (FTCAs), particularly 5:3 FTCA and 6:2 FTCA, were dominant in landfill leachates and other environmental matrixes. FTCAs are also found as common intermediates during the biotransformation of PFAA precursors. Unfortunately, FTCAs have higher bioaccumulating potential and are at least two orders more toxic than their corresponding PFCAs. However, information regarding the potentials and mechanisms of …

A Novel Biomaterial Platform For Cardiac Tissue Engineering, Andrew House

Dissertations

Heart disease is one of the leading causes of death in the world. With a growing demand for in vitro cardiac models that can recapitulate the complex physiology of the cardiac tissue, there is a desire to create novel therapies and treatments. However, due to a lack of fundamental understanding of the heart's inflammatory response to myocardial infarction, the development of new therapies is both time consuming and costly. In this work, a novel approach to fabricating a dynamic hydrogel cardiac platform is reported. This platform better mimics the dynamic changes occurring in the native cardiac tissue microenvironment during cardiac …

Angiogenic Supports For Microvascular Engineering, Zain Siddiqui

Dissertations

Ischemic tissue disease is caused by a lack of circulation / blood supply to tissue. This can be treated by introducing a number of angiogenic (pro-blood vessel forming) factors into the tissue. This work presents strategies for ischemic tissue treatment utilizing a novel proangiogenic self-assembling peptide hydrogel platform. To demonstrate the utility of this platform, its use alone as an angiogenic therapeutic (both alone as a self-assembling hydrogel and with two-component systems), and its ability to vascularize implants is explored. Due to these angiogenic scaffolds demonstrating efficacy to regenerate microvasculature, this work evaluates diseases that can be treated by the …

Evaluation And Revision Of The Practice Environment Scale Of The Nursing Work Index For Acute Care Hospital Staff Nurses, Caitlin M. Campbell

Dissertations

The Practice Environment Scale of the Nursing Work Index (PES-NWI) is the most frequently used instrument for measuring the nursing work environment. The original PES-NWI obtained its items directly from the parent instrument, the Nursing Work Index, which was developed in the 1980s. However, potential value change among younger generations and vast historical, social, and technological transformations in the way healthcare is provided may have led to different factors that compose a favorable work environment for nurses working today.

Educators’ And Parents’ Attitudes Toward The Inclusion Of Students With Emotional And Behavior Disorders, Shannon L. Howze

Dissertations

Educating students with emotional and behavior disorders (EBD) has historically been a difficult task for educators (McKenna et al., 2021). The general education setting comes with many barriers when attempting to include students with EBD to the equation. Parents are instrumental to the success of their students with EBD regardless to the setting. Educators may lack in the skills needed to communicate, educate, and understand students with EBD. Without educators and parents collectively communicating and collaborating, students with EBD will not have the opportunity to have the positive experiences and outcomes to be successful. Applying the theoretical frameworks of Bandura’s …

Using The Social-Ecological Model To Better Understand Sexual Assertiveness Among Undergraduate Women At An Institution Of Higher Education In The Southeastern United States, Lisa Wright

Dissertations

This study examined sexual assertiveness among female undergraduate students at an institution of higher education in the southeastern United States from the context of the social-ecological model. An online survey instrument examined sexual assertiveness, sexual communication self-efficacy, campus climate, and sexual scripts. Structural equation modeling was used to examine the relationships between these variables and all variables significantly predicted sexual assertiveness individually, but when examining the relationships collectively, only sexual communication self-efficacy and campus climate remained significant predictors of sexual assertiveness.

The Presence Of Relational Trust In Teacher-Principal Relationships And The Correlation Of Teacher Intent-To-Persist And Teacher Efficacy, Maryum Bilal

Dissertations

Principals and teachers must work together for students to be academically successful. Teachers directly influence the students, and principals directly affect the teachers. Before students' success can occur, the principal and teachers must have a relationship. The development of trust begins with leaders who have quality relationships with their teachers (Bryk & Schneider, 2002). When teachers trust their principals, teachers are loyal and develop self-efficacy. According to Lacks and Watson (2018), teacher self-efficacy is developed through significant interactions with the principal, making teachers feel better about themselves and their collective mission, and they become more effective in the classroom. Trust …

An Asset Model: Identifying Institutional Characteristics And Behaviors That Close Community College Completion Gaps Between Black And White Students, Courtney Lange

Dissertations

The United States fails to meet its own workforce needs, and estimates show that by the year 2025, almost two out of three jobs in the nation will require at least some postsecondary education or training (Carnevale et al., 2019b). Jobs with the fastest growth rate will require an associate degree (Carnevale et al., 2019b). According to the most recent national data from the National Student Clearinghouse (NSC) Research Center, one in three students begin their college journey at a community college (NCES, 2019). Only 40% finish a degree or credential within six years (NCES, 2019). The proportion of those …

Investigating The Involvement Of The Tick Vector In The Induction Of Alpha-Galactose Hypersensitivity (Alpha-Gal Syndrome, Red Meat Allergy) In The United States., Gary Crispell

Alpha-gal syndrome (AGS or sometimes called red meat allergy) is a result of the development of specific IgE antibodies to the oligosaccharide galactose-α-1,3-galactose (α-gal) after a person has had exposure to tick bites. This dissertation investigates four common tick species found in North America: the lone-star tick (Amblyomma americanum), the Gulf-Coast tick (Amblyomma maculatum), the American dog tick (Dermacentor variabilis), and the black-legged tick (Ixodes scapularis) for the presence of α-gal by utilizing a combination of immunoproteomic approaches and carbohydrate analysis techniques.

Anti-α-gal IgM antibodies (M86) were used in immunoblotting to detect …

Psychological Capital And Perceived Employability: Exploring Women Veterans’ Military-To-Civilian Career Transition, Tundra Gatewood

Dissertations

The veteran human capital remains integral to the U.S. workforce and sustainment of its competitive advantage (Carter, Schafer, et al., 2017). Women constitute 17% of 1.4 million servicemembers and 10% of 18.4 million veterans, with a projected population growth of 18% by 2040 (Defense Manpower Data Center [DMDC], 2021; U.S. Bureau of Labor Statistics, 2020a). Each year, an estimated 30,000 ex-servicewomen enter the national labor force (National Center for Veterans Analysis and Statistics, 2019; U.S. Bureau of Labor Statistics, 2020a). Most of these ex-servicemembers turned veterans must navigate the military-civilian divide and negotiate their economic worth in highly divergent and …

Strategic Human Resource Management Practice Integration And Organizational Ambidexterity In Vuca Times, Gizzatta Cook

Dissertations

ABSTRACT

The failure rate of business strategy implementation hovers around 50% due to a lack of organizational ambidexterity in the realities associated with a four-dimensional paradigm referred to as a volatile, uncertain, complex, and ambiguous (VUCA) environment (Chattopadhyay et al., 2017). Anwar and Abdullah (2021) state that organizational success depends highly on how well organizational leaders manage and administer their human resource management practices. Today's successful organizations must adapt to societal changes to survive and thrive (Chattopadhyay et al., 2017).

Surviving and thriving beyond today’s organizational constraints also involves a business's ability to demonstrate organizational ambidexterity. Organizational ambidexterity is the …

Characterization Of Innate Immune Responses In Mouse Trophoblast Stem Cells And Their Differentiated Cells, Mona Fendereski

Dissertations

The blastocyst is the preimplantation stage embryo consisting of two major components: the inner cell mass (ICM) and the trophectoderm (TE). The ICM forms the fetus, whereas the TE contributes to the placenta development. Previous studies have demonstrated that human and mouse embryonic stem cells (ESCs) derived from the ICM are deficient in expressing type I IFNs in response to viral infection. This study investigated the innate immune responses in mouse trophoblast stem cells (TSCs) and their in vitro differentiated trophoblasts (TSC-TBs). I report that, unlike ESCs, TSCs have a functional IFN system. They can express and respond to type …

The Role Of Mate Seeking Motives, Status Acquisition Motives, And Dark Personality In Predicting Responses To An Aggression-Provoking Situation, Savannah Merold

Dissertations

Aggressive behavior is associated with many adverse consequences, prompting extensive research on the potential adaptive functions of aggression. For example, there is evidence that aggression may be beneficial for attaining status and attracting a potential mate (e.g., Buss & Dedden, 1990; Daly & Wilson, 1988; Griskevicius et al., 2009). Additionally, several personality traits have been identified as robust predictors of aggressive behavior (e.g., psychopathic, Machiavellian, narcissistic, and sadistic traits; Chester et al., 2019; Neumann & Hare, 2008; Paulhus & Jones, 2017; Twenge & Campbell, 2003). These two research traditions (i.e., evolutionary and personality) have remained separate, with few studies combining …
