Cognitive Flexibility: Using Mental Simulation To Improve Script Adaptation, Javier Rivera

Electronic Theses and Dissertations

Human behavior and decision-making depend largely on past experiences that generate specific action patterns (i.e., scripts, Gioia & Manz, 1985) for specific situations. In an ideal world, in which changes in the environment do not conflict with these action patterns, humans would be able to operate consistently, efficiently, and automatically. However, real-world environments are dynamic and fluid, thus altering behavior and forcing changes in scripts. Research suggests that to implement alternate solutions to changing situations, humans select from a "library" of learned scripts. Since humans tend to implement scripts to the degree that these are successful over a period of …

Human Cytosolic Sulfotransferase (Sult) 1b1 Half-Site Reactivity And The Identification And Characterization Of A Novel Variant Sult1b1 Isoform (L145v), Zachary Evan Tibbs

All ETDs from UAB

The human cytosolic sulfotransferases (hSULTs) are a fourteen-member family of phase II drug-metabolizing enzymes that catalyze the transfer of a sulfonate moiety from 3’-phosphoadenosine 5’-phosphosulfate (PAPS) to a recipient substrate. SULT-mediated sulfation serves to deactivate physiological hormones and detoxify xenobiotics. SULT1B1 is primarily resident to the gastrointestinal tract, liver, and possibly peripheral white blood cells (WBCs), whereby it performs its supposed physiological role. The iso-form has the capacity to sulfate thyroid hormones, small phenols, and polyaromatic hy-drocarbons resulting in their inactivation, detoxification, and bioactivation/detoxification, respectively. Immunohistochemistry was used to show hSULT1B1 protein is present in periph-eral lymphocytes and neutrophils. Further, …

Brain-Computer Music Interfacing: Designing Practical Systems For Creative Applications, Joel Eaton

Other Faculty of Arts, Humanities and Business Theses

Brain-computer music interfacing (BCMI) presents a novel approach to music making, as it requires only the brainwaves of a user to control musical parameters. This presents immediate benefits for users with motor disabilities that may otherwise prevent them from engaging in traditional musical activities such as composition, performance or collaboration with other musicians. BCMI systems with active control, where a user can make cognitive choices that are detected within brain signals, provide a platform for developing new approaches towards accomplishing these activities. BCMI systems that use passive control present an interesting alternate to active control, where control over music is …

Food Buzzwords: Understanding How Schemas Of Proper Dieting Are Formed, Sacha Franklin-Jeune

Electronic Theses and Dissertations 2010 - 2019

In the modern United States, the concept of food has become as much of a social phenomenon as it is a biological need. The process of eating has become highly structured into a system of communication. Food terms used to share ideas are referred to as food buzzwords, terms rife with additional meanings whose values are continuously debated, discussed, and altered. Such terminology has swayed how middle-class Americans interpret the proper status quo of food consumption and production. This thesis analyzes how middle-class Americans form their view of a proper diet based on their understanding of food buzzwords and other …

Choreographing Intimacy: The Making Of ‘[They] Slipped Briskly Into An Intimacy From Which They Never Recovered’ – A Dance Film, Antonio Rinaldi

Theses : Honours

In this investigation, I have utilised a practice-led research methodology to capture ‘intimacy’ in film, specifically, the medium of dance film. The exegetical work is divided into the written research with an accompanied dance film component; however they should be viewed as an integrated thesis. The aim of my research was to develop my choreographic practice through a film that is a sensory and evocative exploration of intimacy. I argue that the film components of dance film (directing, cinematography, editing and the like) uniquely capture an intangability of dance and the complexities of human intimacy in a manner that is …

From Sentience To Science: Limits Of Anthropocentric Cognition, Charukeshi Chandrasekera

Animal Sentience

Donald Broom’s Sentience and Animal Welfare (2014) is an intellectually and morally engaging book written with radical new concepts in mind. It deals with many issues that are central to the animal welfare debate such as brain complexity, cognitive ability, when in life sentience begins, and how it all affects the way we endorse welfare. It addresses how our insatiable quest to define the uniqueness of our own species has led us to ignore logic and scientific evidence. It also brings greater clarity to these precarious positions and outlines pragmatic approaches to tackling this complex topic of sentience and welfare.

Healthy Weight Maintenance: Narrative Analysis Of Weight Cycling In The Formerly Obese, Cheri Renee Lewis

Walden Dissertations and Doctoral Studies

Medical and economic costs for obesity are estimated at $147 billion per year, yet less than 1/3 of overweight individuals successfully maintain weight loss. The literature is replete with descriptions of the problem and research on treatments, yet demonstrations of effective loss and maintenance are lacking. Missing is an understanding of the experiences of individuals who successfully maintained healthy weight loss, which could provide insights regarding effective psycho-social interventions. The purpose of this qualitative narrative study was to explore key events and experiences in the lives of former weight cyclers. The primary phenomena of interest included weight cycling and sustained …

An Evaluation Of Individuals' Construction Of Personal Trust In Organizations, Colin Edward Armour

Walden Dissertations and Doctoral Studies

Trust is in decline within organizations resulting from poor management and ethical indifference. Failing to address trust perceptions has led to stress between management and employees. Researchers have studied organizational trust as a constant quality within groups but have neglected the uniquely individual constructs of trust that inhibit trust-building efforts. The purpose of this quantitative study was to evaluate how personal constructs of trust may affect outcomes at the organizational level among workers and managers in hierarchal structured organizations. The topics of the research questions addressed the extent which cultural values and the relative trust situation affected individuals' perceptions of …

The Impact Of Hydration Status During Heat Acclimation On Physiological Strain And Exercise Performance, Michael W. Schleh

Heat acclimation promotes adaptations to attenuate physiological and perceptual strain associated with heat stress, and may be enhanced by promoting dehydration during acclimation. Purpose: To determine i) the effect of fluid delivery during acclimation by inducing dehydration (DEH=0.5 mL / kg / 15 min) vs. euhydration (EUH=2.0 mL / kg ^/ 15min) following three heat acclimation bouts on heat stress factors, and ii) to determine if fluid delivery (EUH vs. DEH) affects aerobic performance in the heat. Methods: Thirteen aerobically fit males completed 90-minute heat stress test (HST) in hot conditions (40°C, 30% RH) walking at 50% VO₂ max …

The Relationship Between Non-Human And Human Research And The Scientific Construction Of Race, Gender, And Sexuality, Shayna Marie De Ruysscher

Harriet L Wilkes Honors College Theses 2010 - 2019

My thesis focuses on the relationship between science and non-human research studies. Specifically, I will look at the role that ‘animals’ play in the scientific construction of race, gender, and sexuality. In what ways has the scientific construction of the dichotomy between primates and human beings been used in science to create racial, gender and sexual dichotomies? In what ways are the resulting consequences of such dichotomies in medical fields a reflection of these constructions? My research attempts to show various ways in which language and interpretations established by science help to create a dichotomy between animals and humans, which …

Over the last several years, use of e-books in higher education has increased significantly and is projected to continue through the next decade. Institutions of higher learning have implemented use of e-books without any data that verified the impact on student learning outcomes. The purpose of this ex post facto, quantitative study was to compare student learning outcomes in Human Anatomy and Physiology I courses using e-books versus using traditional textbooks at a two-year public community college in South Texas. With a participant population of 686 students, data were analyzed by their final grades comparing the differences between those who …

The Image Machine, Jeremy Min Burns

Architecture Senior Theses

Architecture has always been an image machine. From the Lascaux cave paintings to the Sainte-Chapelle in Paris to the multimedia installations of the Eameses to the early projects of Diller Scofidio, images and architecture have cohabited persistently and productively for centuries. However, since the dawn of the digital age, the ontological status of images has changed; and in turn so has the relationship between images and architecture. Rather than being anchored to a specific material support, images exist as manipulable data. While some have viewed the digital turns as the transcendence of information beyond the human subject, an era of …

Synthesis Of Carbon-11 Labeled Organic Molecules For Pet Studies, So Jeong Lee

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

PET has played a key role in the field of molecular imaging and nuclear medicine over the past decades. PET represents a non-invasive molecular imaging technique to study and visualize human physiology by detecting positron-emitting radiopharmaceuticals labeled with short half-live radioisotopes (i.e. | 11C, 13N, 15O, and 18F) that visualize in vivo biochemical processes and metabolic pathways (i.e. | glycolysis and protein/DNA synthesis). PET is also an emerging method for measuring body function and tailoring disease treatment in living human by detecting biochemical changes preceding anatomical changes occurring a disease. The capability of imaging quantitatively and with high sensitivity without …

The Effects Of Passive, Active, And Beta-Alanine Supplemented Recovery On Blood Lactate During Anaerobic Exercise, Tracey Hampshire

2015 Fall Honors Capstone Projects - Archive

It is widely shown through experimentation and knowledge of human physiology that an active recovery following high-intensity exercise removes lactic acid (BLa) more quickly than passive recovery. Some research suggests that Beta-Alanine (BA) supplementation can decrease BLa levels following supramaximal exercise. The purpose of this study was to assess whether passive, active, or Beta-Alanine supplemented recovery was more effective at lowering BLa accumulation anaerobic exercise. Nine subjects participated in this experiment (one subject was excluded). Each completed three sessions of active, passive, or supplemented Wingate protocols. Results were determined using SPSS (p < 0.05). There was no statistically significant difference between active and passive recovery (p = .292) or between BetaAlanine and placebo groups (p = .962). The results of this study indicated that there were no differences between BLa in passive and active recovery, and no benefits of Beta-Alanine supplementation on BLa accumulation following supramaximal exercise.

Determination Of Total And D-Amino Acid Content In Mice Brain Tissue By Achiral-Chiral Heart-Cutting Two-Dimensional Liquid Chromatography: Diagnostic And Clinical Relevance And A Comparison Between Non-Perfused And Perfused Tissue, Curran Parpia

Chemistry & Biochemistry Theses - Archive

A heart-cutting two dimensional liquid chromatographic method for the quantification of free amino acid enantiomers from mouse brain tissue is demonstrated. Evidence to support the occurrence of D-amino acids in significant concentrations in physiological samples has spurred studies toward the elucidation of their importance and function. In this work, the level and regional distribution of select amino acids were determined by achiral-chiral LC/LC. Additionally, the effect of tissue perfusion on these levels was investigated. The free amino acid extracts were analyzed as their 9-fluorenylmethyloxycarbonyl derivatives and separated in the reverse phase mode on superficially porous C18. In the second dimension, …

Systemic Insulin Sensitivity And Skeletal Muscle Akt Signaling In Rats Artificially Selected For Low And High Aerobic Capacity, Kyle Levi Fulghum

Graduate Theses/Dissertations

The mechanism(s) linking physical inactivity, obesity, and type-II diabetes are unclear. I hypothesized low intrinsic aerobic capacity is associated with reduced systemic insulin sensitivity via skeletal muscle insulin signaling. After 34 generations of selective breeding, high aerobic capacity (HCR) rats exhibited an 8-fold increase in running distance vs low aerobic capacity (LCR) rats (n=14 per group). LCR rats had higher rates of weight gain vs HCR (p<0.05) though food consumption was constant (p=0.86) over a 12-week study. Rats were divided into 4 groups: 1) LCR-Sham Surgery, 2) LCR-Catheterization, 3) HCR-Sham Surgery or 4) HCR-Catheterization (n=7 per group). Euglycemic-hyperinsulinemic clamps on catheterized rats tested insulin sensitivity while sham LCR and HCR were used for basal tissue analysis. Plasma insulin levels did not differ during the clamps, but LCR required lower glucose infusion rates than HCR (p<0.05). Upon insulin stimulation, both absolute and normalized phospho-Akt(Ser473) of soleus muscle were significantly increased in HCR above basal group (p<0.05), but not in LCR. No difference was observed between insulin-stimulated phospho-Akt(Ser473) of HCR and LCR groups . These data support that LCR is linked to a reduction in insulin sensitivity in vivo without impairments of insulin-stimulated skeletal muscle phospho-Akt(Ser473) vs HCR rats.
