Reward-Related Predictors Of Relapse In Smokers, Elena Molokotos

Graduate Theses and Dissertations

Quitting smoking remains an on-going challenging for many cigarette smokers. Numerous individualized characteristics have been suggested as predictors for successful smoking abstinence. One such factor requiring further investigation is reward responsivity, given that individuals with addiction show behavioral and neurobiological alterations in reward function.This study used previously collected data from 122 daily smokers to investigate whether individuals willing to abstain from smoking in exchange for money would display increased reward responsivity during a baseline, non-abstinent visit, relative to individuals who smoked immediately. Participants Probabilistic Reward Task (PRT) performance was used to measure reward responsivity to monetary rewards and a laboratory-based …

Intervals, Nicolette Bonagura

Graduate Theses and Dissertations

Intervals investigates the complexities of visual perception, using the camera as a tool to document time and light. The photograph is a restricted experience dually existing as a physical impression of light onto a surface and a fixed representation that makes light tangible. Using time and light as my subject and ritualistic gathering as my methodology, I explore the complexities of control and perception as they relate to photography. I collect images of everyday occurrences; and then use those as material to both compress and expand time. I do this to interrupt our understanding of it. Documenting time through mundane …

Numerically Modeling Steel Continuous Bridges For Early Age Concrete Deck Cracking, Abdul Aziz Nabil Salah

Graduate Theses and Dissertations

Early age bridge deck cracking is a common problem throughout the United States. Early age cracking develops shortly after the deck is poured. It reduces the serviceability and lifespan of bridges. Early age cracking can be typically attributed to either of two factors, 1) construction practices, and 2) shrinkage. The Arkansas Department of Transportation (ARDOT) has experienced early age bridge deck cracking. ARDOT currently specifies a sequence deck pour on most of their bridges; however, contractors prefer continuous deck pours because of ease and construction time. During the period of this TRC1903 research project, ARDOT has only approved a few …

Numerical Simulations Of Spread Foundations Supported On Stone Columns Using The Discrete Element Method, Anibal Enrique Santos Marin

Graduate Theses and Dissertations

The implementation of stone columns as a ground improvement technique has become more popular in geotechnical construction practice as a result of their ability to improve strength, stiffness and permeability characteristics of weak clayey soil deposits. There are several analytical and empirical approaches to estimate the bearing capacity of stone column foundation systems; however, there is notable variation in the performance of these existing methods when compared with full-scale experimental results. For very weak cohesive soils (i.e., undrained shear strength less than 15 kPa), the use of conventional stone columns becomes restricted because of the insufficient confinement that these types …

An Experimental Test Of The Effects Of Sleep Deprivation On Approach Behavior, Rebecca L. Campbell

Graduate Theses and Dissertations

Emotion regulation and sleep have been identified as mechanisms that may be involved in the development and maintenance of many mental health disorders. However, there has been little research into the relation between sleep and emotion regulation. To address this gap in knowledge, a novel study was conducted. We hypothesized that sleep deprived individuals would demonstrate less approach behavior toward a negatively valenced stimulus, as well as increased self-reported avoidance, compared to a control group. To test this, a randomized controlled experiment using a behavioral measure of approach and a self-report measure of avoidance was conducted. Fifty-two healthy individuals ages …

Shakespeare In The Eighteenth Century: Algorithm For Quotation Identification, Marion Pauline Chiariglione

Graduate Theses and Dissertations

Quoting a borrowed excerpt of text within another literary work was infrequently done prior to the beginning of the eighteenth century. However, quoting other texts, particularly Shakespeare, became quite common after that. Our work develops automatic approaches to identify that trend. Initial work focuses on identifying exact and modified sections of texts taken from works of Shakespeare in novels spanning the eighteenth century. We then introduce a novel approach to identifying modified quotes by adapting the Edit Distance metric, which is character based, to a word based approach. This paper offers an introduction to previous uses of this metric within …

Determination Of Critical Y-Leaf Potassium Concentrations Across Reproductive Growth Stages For Direct-Seeded Delay-Flooded Rice, Chandler Edwin Gruener

Graduate Theses and Dissertations

Rice (Oryza sativa L.) grain yield can be limited by potassium (K) deficiency on soils low in exchangeable K. Visually diagnosing K deficiency during early reproductive growth is not easily done and the interpretation of traditional tissue analysis is limited to select growth-stages. Our primary focus was to define continuous critical Y-leaf-K concentrations during reproductive growth for the production of maximal grain yield. A secondary objective was to examine Y-leaf sap-K concentration, measured using a handheld device, as a rapid in-field method of monitoring rice plant K nutrition. The Y-leaf is defined as the uppermost fully extended leaf with a …

Graduate Theses and Dissertations

The hypothalamo-pituitary-adrenal (HPA) axis is the regulatory system for the neuroendocrine stress response within vertebrates. Within the HPA axis corticotropin releasing hormone (CRH) is a major regulator and driving hormone. A structure named the nucleus of the hippocampal commissure (NHpC) has been found to contain CRH neurons and also these neurons respond to early food deprivation stress significantly prior to the paraventricular nucleus (PVN), the major driving nucleus of the classic neuroendocrine HPA axis. The objective of this study was to perform a knock down of the NHpC via electrolytic lesioning, thus eliminating a significant portion of its population of …

Achieving Causal Fairness In Machine Learning, Yongkai Wu

Graduate Theses and Dissertations

Fairness is a social norm and a legal requirement in today's society. Many laws and regulations (e.g., the Equal Credit Opportunity Act of 1974) have been established to prohibit discrimination and enforce fairness on several grounds, such as gender, age, sexual orientation, race, and religion, referred to as sensitive attributes. Nowadays machine learning algorithms are extensively applied to make important decisions in many real-world applications, e.g., employment, admission, and loans. Traditional machine learning algorithms aim to maximize predictive performance, e.g., accuracy. Consequently, certain groups may get unfairly treated when those algorithms are applied for decision-making. Therefore, it is an imperative …

Development Of The Caregiver-Child Auditory Skills Tracking (Cast) Scale: A Pilot Study On Caregiver Implementation Via International Telepractice, Elizabeth Ocampo-Roman

Graduate Theses and Dissertations

Parent engagement is a key component during early language development for all children, but particularly for a child with hearing loss. Through the application of technology-based models of service delivery such as telehealth, researchers have found an increase in parent-child engagement during auditory-verbal therapy (AVT) sessions due to the physical absence of the provider and parents becoming the primary language facilitators. However, current measures of parent-child interactions do not have a coding system to monitor facilitation of auditory skills. This present study will discuss the development of the Caregiver-Child Auditory Skills Tracking (CAST) Scale to track progress of caregiver implementation …

The Postsecondary Enrollment Of Black American Men: The Perceived Influence Of Environmental Factors, David V. Tolliver, Iii

Graduate Theses and Dissertations

In the United States, there has been a consistent under-enrollment of Black American men who have enrolled and graduated from four-year colleges and universities. The result of this lack of educational attainment is problematic, as it can be seen in lower employment rates, higher under-employment rates, higher rates of incarceration, poorer health, and even a lower quality life. Institutional leaders and policymakers have struggled to find solutions for increasing the participation of Black American men with largely mixed results. Most of these programmatic attempts, however, have been limited in their approach and have not taken into account family and informal …
