Extended Adolescence: The Ecology And Endocrinology Of Facultative Paedomorphosis, Jason R. Bohenek Jan 2019

Extended Adolescence: The Ecology And Endocrinology Of Facultative Paedomorphosis, Jason R. Bohenek

Electronic Theses and Dissertations

Phenotypic plasticity is an adaptation to unpredictable environments whereby an organism of a single genotype may express more than one phenotype under differing environmental conditions. Phenotypic plasticity can manifest as polyphenisms, which is an extreme form of phenotypic plasticity that produces two or more discrete, alternative phenotypes. The expression of alternative phenotypes is controlled by biotic and abiotic environmental factors, which variably affect the strength and direction of phenotypic outcomes. Using a model polyphenic salamander, I sought to understand the ecological and hormonal processes that regulate alternative phenotype expression. The mole salamander (Ambystoma talpoideum) and eastern newt ( …

Allodynia And Self-Efficacy In Migraineurs, Ashley N. Polk Jan 2019

Allodynia And Self-Efficacy In Migraineurs, Ashley N. Polk

Electronic Theses and Dissertations

Headache disorders are among the most comdisorders of the nervous system, with migraine alone affecting 14% of women and 6% of men worldwide each year. Headache-related self-efficacy, or one’s confidence in preventing and managing headache, is particularly important for prevention and management of headache disorders and predicts response to behavioral and pharmacological treatments. Allodynia, the perception of non-noxious stimuli as painful due to central sensitization, compounds headache-related disability and compromises efficacy of triptans. Therefore, migraineurs with allodynia may perceive headache treatments as less efficacious and thus have reduced perceived headache-related self-efficacy. However, no literature to date has explored the relationship …

Behavioral Inhibition And Avoidance: Identifying Vulnerabilities To Avoidant Behavior, Daniel Pineau Jan 2019

Behavioral Inhibition And Avoidance: Identifying Vulnerabilities To Avoidant Behavior, Daniel Pineau

Electronic Theses and Dissertations

Avoidance is characterized as the inability of an individual to interact with a stimulus for the purpose of reducing distress. Avoidance increases the likelihood that distress and symptoms related to anxiety will increase. This may lead to further impairment and anxious pathology across the lifespan. Reinforcement Sensitivity Theory (RST) describes a temperamental vulnerability that influences approach (Behavioral Approach System; BAS) and avoidance (Behavioral Inhibition System; BIS) behaviors. The purpose of the study was to identify, using observed behavioral approach tasks, whether or not BIS/BAS influenced avoidant behavior above and beyond other avoidance vulnerabilities (anxiety sensitivity and emotion dysregulation). Participants (N=297) …

The Effects Of Technology Based Self-Monitoring Across General Education Settings For Students With Behavior Disorders, Lane Maxcy Jan 2019

The Effects Of Technology Based Self-Monitoring Across General Education Settings For Students With Behavior Disorders, Lane Maxcy

Electronic Theses and Dissertations

This dissertation consists of three articles investigating the effects of technology-based self-monitoring to decrease off-task behaviors and increase academic engagement in students who have behavior disorders. Previous literature has examined the effects of technology-based self-monitoring in special education and alternative placements. Unfortunately, there is a lack of investigation with technology-based self-monitoring in general education settings. Together these three articles will clearly determine the effects of technology-based self-monitoring in general education settings specifically for students with behavior disorders.

Reward And Punishment: The Neural Correlates Of Reinforcement Feedback During Motor Learning, Christopher Mark Hill Jan 2019

Reward And Punishment: The Neural Correlates Of Reinforcement Feedback During Motor Learning, Christopher Mark Hill

Electronic Theses and Dissertations

‘By the carrot or the stick’ reward or punishment has been contemplated by instructors to motivate their pupils to learn a new motor skill. The reinforcements of reward and punishment have demonstrated dissociable effects on motor learning with punishment enhancing the learning rate and reward increasing retention of the motor task. However it is still unclear how the brain processes reward and punishment during motor learning. This study sought to investigate the role of reinforcement feedback in cortical neural activity associated with motor learning. A novel visuomotor rotation task was employed with reward punishment or null feedback as the participants …

The Medicine Hat Block And The Assembly Of Laurentia: New Interpretations From Single-Grain Zircon Analyses, Blake Oswell Ladouceur Jan 2019

The Medicine Hat Block And The Assembly Of Laurentia: New Interpretations From Single-Grain Zircon Analyses, Blake Oswell Ladouceur

Electronic Theses and Dissertations

The Medicine Hat Block (MHB) is one of the core cratonic elements that amalgamated in the Paleoproterozoic to form Laurentia. However the role of the MHB in the formation of Laurentia is poorly constrained due to virtually all of the MHB being concealed by Proterozoic and younger supracrustal sequences limiting availability of data. The primary sources of samples from the MHB are 1) xenoliths of variable metamorphic grade including gneisses amphibolites and meta-plutonic rocks collected from Eocene volcanic rock; and 2) similar lithologies recovered from boreholes that penetrate to the MHB basement. Previous work on samples from the MHB yielded …

My Feet Are Chained: Settler Colonialism And Mobility In The Florida Borderlands, 1812-1866, Christine Antoinette Rizzi

Electronic Theses and Dissertations

This project uses the framework of mobility to understand how settler colonialism functioned in a tri-racial southern borderland in the nineteenth-century. Nineteenth-century Florida constituted a borderland characterized by competition for land and resources among Seminole Indians, African Americans, and white Americans. White Americans regulated mobility, i.e. the physical movement of peoples, in order to privilege their own settlement in Florida, divest native peoples of their land, and enslave people of African descent. Beginning in 1812 and lasting through the first half of the 1860s, white Americans used legislation, the settlement of white families, the solidification of a slave system, and …

Analysis Of Brevundimonas Subvibrioides Developmental Signaling Systems Reveals Unexpected Differences Between Phenotypes And C-Di-Gmp Levels, Lauryn Anne Sperling Jan 2019

Analysis Of Brevundimonas Subvibrioides Developmental Signaling Systems Reveals Unexpected Differences Between Phenotypes And C-Di-Gmp Levels, Lauryn Anne Sperling

Electronic Theses and Dissertations

The DivJ-DivK-PleC signaling system of Caulobacter crescentus is a signaling network that regulates polar development and the cell cycle. This system is conserved in closely related bacteria, including the sister genus Brevundimonas. Previous studies had shown unexpected phenotypic differences between the C. crescentus divK mutant and the analogous mutant of Brevundimonas subvibrioides, but further characterization was not performed. Here, phenotypic assays analyzing motility, adhesion, and pilus production (the latter characterized by a newly discovered bacteriophage) revealed that divJ and pleC mutants have mostly similar phenotypes as their C. crescentus homologs, but divK mutants maintain largely opposite phenotypes than …

Building An Automated Q-A System Using Online Forums As Knowledge Bases, Kyle Moore Jan 2019

Building An Automated Q-A System Using Online Forums As Knowledge Bases, Kyle Moore

Electronic Theses and Dissertations

Question-Answer systems traditionally use expensive and difficult to produce structured knowledge bases. Recent systems have used unstructured natural language sources as their datasets, but most of those sources have been overly broad or difficult to extend. Online forums are a largely untapped source of information that can provide both depth and breadth when limited to a specific domain, as well as being adaptive to the introduction of new information. In this paper, I conjecture that online forums can be similarly and effectively used as an unstructured knowledge base for Question-Answer systems. I use a relatively simple summarization-based approach to analyze …

Predictors Of Behavioral Health Among Firefighters In Their Third Year Of Fire Service, Victoria Alicia Torres Jan 2019

Predictors Of Behavioral Health Among Firefighters In Their Third Year Of Fire Service, Victoria Alicia Torres

Electronic Theses and Dissertations

Employee turnover is expensive, as job training can cost upwards of 30% of an employee’s annual salary (not including additional onboarding expenses; Boushey & Glynn, 2012). This is especially true among high stress, dangerous occupations that require specialized training such as firefighters (Envisage Technologies, 2016; Knoll, 2011; Patterson et al., 2010). Health status is a primary reason for job concerns that may lead to decline in job performance and employment separation (Hourani, Williams, & Kress, 2006; Virtanen, Kivimäki, Vahtera, Elovainio, Sund, Virtanen, & Ferrie, 2006). Two research areas that support this notion include literature on the biopsychosocial model and occupational …

Validation Of A Brief Screening Instrument For Psychopathology In Adults, Adam Sattler Jan 2019

Validation Of A Brief Screening Instrument For Psychopathology In Adults, Adam Sattler

Electronic Theses and Dissertations

Structured diagnostic interviews are generally considered to be the gold standard method of assessing mental health conditions; however clinicians rarely use such techniques in clinical practice. A major factor contributing to the infrequent use of structured interviews is the amount of time required for administration and interpretation. As such there is a need to develop assessment instruments that balance the objectivity and structure of evidence-based assessment techniques against personnel time and cost. To address this need the current study sought to validate a brief screening instrument for assessing 9 commental health conditions using a well-researched structured clinical interview to establish …

Teaching Kids To Say "Ew!": Parent-Child Disgust Transmission, Brooklee Lightsey Tynes Jan 2019

Teaching Kids To Say "Ew!": Parent-Child Disgust Transmission, Brooklee Lightsey Tynes

Electronic Theses and Dissertations

Disgust is one of the six basic emotions but research suggests it is far more complex. As individuals respond to stimuli in different manners this suggests the emotion and its development may be shaped through learning principles and cultural practices (Rozin Lowery & Ebert 1994). It is imperative to understand how children’s disgust responses are shaped though observation classical and operant conditioning demonstrated by their primary caregivers. The current study examined the transmission of the emotion of disgust from primary caregivers to their children. Participants were 17 children (55.6% female) and one of their parents in Mississippi and Nebraska. The …

Emotion Regulation As A Predictor Of Pediatric Obsessive-Compulsive Symptoms, Brittany Spence Sapp Jan 2019

Emotion Regulation As A Predictor Of Pediatric Obsessive-Compulsive Symptoms, Brittany Spence Sapp

Electronic Theses and Dissertations

Research findings suggest that emotion regulation (ER) is a key component in the maintenance and development of psychopathology. However there is a paucity of research assessing ER and Obsessive-Compulsive (OC) symptoms particularly how ER relates to OC tendencies in children. Due to the pervasive nature of both ER difficulties and OC symptoms across major life domains (i.e. familial social academic) and the lasting impact of these problems into adulthood further research is needed to better understand this connection. The present study investigated this relation in a clinical sample of 472 youth (ages 10 – 17) who completed a packet of …
