3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications

Description: This study investigated a new approach to achieving high energy density supercapacitors (SCs) by using high surface area self-activated carbon from waste coffee grounds (WCGs) and modifying 3D printed electrodes' porous structure by varying infill density. The derived activated carbons' surface area, pore size, and pore volume were controlled by thermally treating the WCGs at different temperatures (1000˚C, 1100˚C, and 1200˚C) and post-treating with HCL to remove water-soluble ashes and contami… more

Adult Attachment, Racial-Ethnic Identity, Racial-Ethnic Socialization, and Subjective Wellbeing

Description: The current study aimed to explore the direct effect of insecure adult attachment on subjective wellbeing and its indirect effect via racial-ethnic identity. Additionally, the present study examined the extent to which racial-ethnic socialization practices may moderate adult attachment and racial-ethnic identity link. The final sample included 213 emerging adults (M = 20.94; SD = 2.96) with diverse racial-ethnic backgrounds. PROCESS Model 4 and 1 were used to examine the direct and indirect eff… more

Air Breathing Fish: Development of Air Breathing in Bristlenose Plecos (Ancistrus cirrhosus)

Description: The bristlenose pleco (Ancistrus cirrhosus) is a species of armored catfish in the Loricariidae family that breathes air facultatively when the aquatic environment becomes hypoxic. The bristlenose pleco uses its highly vascularized stomach as an air breathing organ. The two main goals of this developmental study were to determine the size of onset of air breathing and to determine the frequency of air breathing behavior in bristlenose plecos from juveniles to adults. Developing juveniles reach … more

Ambient Darkness and Consumer Behavior

Description: Ambient lighting has emerged as a key atmospheric factor influencing how consumers process environmental cues and their behaviors. However, surprisingly little research has examined how people think and feel in the dark (lower than 15 lux). This is particularly relevant given that consumers routinely work, pay bills, relax, consume and make purchases in settings with little or no light. My dissertation addresses this gap by examining how consumers regulate their goals and process information wh… more

Anti-S2 Peptides and Antibodies Binding Effect on Myosin S2 and Anti-S2 Peptide's Ability to Reach the Cardiomyocytes in vivo and Interfere in Muscle Contraction

Description: The anti-S2 peptides, the stabilizer and destabilizer, were designed to target myosin sub-fragment 2 (S2) in muscle. When the peptides are coupled to a heart-targeting molecule, they can reach the cardiomyocytes and interfere with cardiac muscle contraction. Monoclonal antibodies, MF20 and MF30, are also known to interact with light meromyosin and S2 respectively. The MF30 antibody compared to anti-S2 peptides and the MF20 antibody is used as a control to test the central hypothesis that: Both … more

An Assessment and Intervention Model for Establishing Observational Learning during Tact Trials

Description: Observational learning (OL) allows an individual to acquire novel responses by observing others' behavior and the corresponding consequences. The complexity of skills involved with OL may vary with the learning context. A learner may observe modeled responses to both trained (known) and untrained (unknown) stimuli or they may observe both reinforced (correct) and nonreinforced (incorrect) responses. The purpose of this study was to develop assessment and training procedures for OL component ski… more

An Assessment of Digital Stimulus Prompts to Teach Conditional Discriminations to Children with Autism

Description: Effective and efficient skill-acquisition procedures must be identified to support individualized behavioral programming for children with autism spectrum disorder (ASD). To do this, practitioners and researchers may use assessment-based instruction. Prompts are a common teaching strategy to promote skill acquisition. The purpose of this applied study was to use assessment-based instruction to evaluate the efficacy and efficiency of within- and extra-stimulus prompts to teach conditional discri… more

Behavioral Transportation: The Role of Psychological, Cognitive, and Social Factors in Distracted Driving Behavior

Description: Logistics 4.0 suggests that increased automation can enhance performance, while Logistics 5.0 emphasizes the advantages of a modern workforce that combines humans and emerging technologies. However, the logistics industry needs a deeper understanding of human factors, an area that has been overlooked so far. To bridge this research gap, this dissertation investigated distracted driving behavior among individuals involved in transportation and logistics-based applications. This investigation emp… more

Blockchain for AI: Smarter Contracts to Secure Artificial Intelligence Algorithms

Description: In this dissertation, I investigate the existing smart contract problems that limit cognitive abilities. I use Taylor's serious expansion, polynomial equation, and fraction-based computations to overcome the limitations of calculations in smart contracts. To prove the hypothesis, I use these mathematical models to compute complex operations of naive Bayes, linear regression, decision trees, and neural network algorithms on Ethereum public test networks. The smart contracts achieve 95\% predict… more

Burnout and Psychological Wellbeing among Taiwanese and American Graduate Students in Mental Health Services: Role of Adult Attachment, Emotion Regulation, and Self-Compassion

Description: Graduate students in mental health service training programs are at risk of experiencing burnout. Using adult attachment theory as the guiding framework, this study examined a conceptual model which depicted the direct and indirect effect of attachment insecurity on burnout and the subsequent psychological distress via low self-compassion and emotion regulation difficulty with two cultural samples recruited from the U.S. and Taiwan, respectively. The final sample included 216 U.S. mental health… more

Can In-vivo Self-Monitoring Improve Discrete Trial Instruction Implementation?

Description: Beneficial consumer outcomes are most likely when behavior-analytic interventions are implemented with high procedural fidelity (i.e., degree to which the procedure is implemented as intended). Video self-monitoring, which involves teaching staff members to monitor their own procedural fidelity when watching recordings of themselves, can be used to improve and maintain high procedural fidelity, but video self-monitoring requires additional staff time and resources. In-vivo self-monitoring, whic… more

Comparison of Neighborhood Demographics and Post-Buyout Land Use Development in Harris County, Texas, USA

Description: Recent research suggests that race and ethnicity influence post-buyout land management in Harris County, Texas, yet lacked systematic empirical evidence to fully understand the relationship between management and demographics. To address this gap, this study analyzes post-buyout land use management practices and compares them with the socio-economic characteristics of the adjacent neighborhood at the block level in Harris County, Texas, an area with a long buyout history.

A Computational Study of Palladium (II) bis(NHC) Complexes and a Computational/Experimental Study of Gold (I) bisADC Complexes Utilizing Non-Covalent Interaction for Catalysis

Description: Carbene ligands over these years have become a heavily utilizes and effective ligand for catalysis. The diamino carbene class of ligands are slightly less understood. The effects of bis(carbene) ligand structures of palladium (II) catalysts were investigated using the ETS-NOCV method. The results showed that the amount of π-backbonding played a major role in the rate of the reaction for these NHC complexes. The amount of pi acceptance from the ligand increased in correlation to the length of th… more

Countering hate speech: modeling user-generated web content using natural language processing

Description: Social media is considered a particularly conducive arena for hate speech. Counter speech, which is a "direct response that counters hate speech" is a remedy to address hate speech. Unlike content moderation, counter speech does not interfere with the principle of free and open public spaces for debate. This dissertation focuses on the (a) automatic detection and (b) analyses of the effectiveness of counter speech and its fine-grained strategies in user-generated web content. The first goal is … more
