Electronic Theses and Dissertations

Using standardized methodology outlined by the United States Forest Service and the National Forests and Grasslands in Texas’ Fire Monitoring Program for data collection, the efficacy of current Forest Service prescribed burn regimes were analyzed for 24 study sites in East Texas National Forests. Study sites were located within Sam Houston, Davy Crockett, and Angelina/Sabine National Forests. Efficacy was determined by comparing defined management objectives established by the Forest Service to the data collected at the study sites. The results conclude that most objectives, as outlined by the Forest Service, are not being met with the current practices. Re-visitation of …

Demographics, Experiences, And Management Preferences Of Backcountry Campers In Yellowstone National Park, Ryan P. Grisham

Electronic Theses and Dissertations

A questionnaire was distributed to backcountry campers in Yellowstone National Park for the summer of 2016. Upon registering for a backcountry camping permit, park rangers asked if campers would like to participate in the survey, which included questions regarding demographics and opinions on visitor experiences and management policies. Participants provided their names and email address and were sent a link to the questionnaire about two weeks after their trip. The survey was a partial replication of a study by Tim Oosterhous conducted in 1999 and results for both years were analyzed and compared to identify any changes in backcountry use …

Exploding Aliens And Other Offspring, Jonathan Patrick Grant

Electronic Theses and Dissertations

The goal of Exploding Aliens and Other Offspring is to capture my specific surrealist world point of view provided by the closed-knit crazy community I grew up in alongside my love for cartoonish melodrama. The collection progresses in order of images and the evolution of such themes as the venture from childhood to adulthood, societal obligations, religion, parenting, death and the hereafter.

To The Effort Itself: A Phenomenological Study Of Wang Yangming's 王陽明 Theory Of Moral Effort, Minglai Dong

Electronic Theses and Dissertations

In this dissertation, I phenomenologically clarify the theory on moral effort (gongfu 功夫) of the sixteenth-century Chinese philosopher Wang Yangming (or Wang Shouren 王陽明/王守仁 1472-1529). For Wang, the final purpose of moral effort is to cultivate one’s heart (xin 心) as the subject of consciousness, with the goal of sagehood. The heart is also the foundation on which all methods of moral effort can rely. I argue that Husserl’s phenomenology can shed a light on Wang’s doctrine, for it describes the transcendental structure of all aspects related to consciousness, which are also topics and phenomena studied by Wang’s …

The Impact Of Mother And Father Stress On Child Externalizing Behaviors, Allison Mccobin

Electronic Theses and Dissertations

The impact of parental stress on child behavioral problems has often been examined through research. A large majority of research indicates a strong correlation between parenting stress and an increase in child behavioral difficulties. However, most studies have focused only on the impact that one parent’s stress has on the child’s behavior, rather than both or comparing the two. Using two separate cross-lagged structural equation models, data from the Fragile Families Child and Wellbeing Study (N = 1010) were analyzed to examine the differences between mother and father parenting stress on child externalizing behavior problems over time (ages three and …

The Philosophical Heritage Of Desire For God In Ibn Ṭufayl’S Ḥayy Ibn Yaqẓān, Bethany Somma

Electronic Theses and Dissertations

This dissertation investigates the role of desire in Ibn Ṭufayl’s Ḥayy Ibn Yaqẓān through a philosophical investigation of desire from Plotinus to Ibn Ṭufayl. I examine Plotinus’s account of desire for the Good, and I argue that this desire forms the basis of his account of substance, such that this desire is non-rational, permanent, fundamental to all hypostases. I also examine the Arabic translations of Plotinus’s text, arguing that the role of desire for God is severely diminished. Indeed, the desire for God we find in these texts is rational and non-permanent – a modified version of the Plotinian model. …

Posttraumatic Growth: The Lived Experience Of Recurrent And Multiple Trauma Survivors Of Kenya’S Skirmishes, 2007 Post-Election Violence, And 2009 National Level Oil Tanker Fire Explosion, Jane C. Lang'at

Electronic Theses and Dissertations

Current research has associated the benefits of posttraumatic growth (PTG) with high levels of stress and trauma that challenge the victim’s assumptive world. The literature reveals that extensive research on PTG has been done on the American, European, and Asian continents but not on the African continent. Yet, how trauma survivors make meaning out of their lived experiences may not be the same globally. This universal phenomenon may also have varied interpretations based on the frequency, intensity, and scope of the traumata, along with the survivors’ socio-economic status (SES) and other benefits and risk factors. In addition, anticipation for high-risk …

Self-Assembling Bioaffinity Hydrogels For Localized Antibody Delivery, Wen Liu

Electronic Theses and Dissertations

The scope of illnesses that are being treated using monoclonal antibodies (mAbs) has been expanding from cancers to autoimmune diseases due to their high specificity to their molecular target. Because many of the new mAbs are aimed to modulate the immune system, an emerging concern is that patients with chronic illnesses are subjected to immune-related Adverse Events (irAEs). Loss of immunological tolerance to self-antigens or increased susceptibility to infections have been documented in some mAb treatments. Localized sustained release of mAb at disease sites might mitigate the risk of such toxicities. Antibody drugs are formulated typically for parenteral delivery because …

Economics Of Managing Loblolly Pine Plantations For Increased Wildlife Biodiversity, Melissa Griffith

Electronic Theses and Dissertations

The goal of this thesis was to identify the differences between the costs incurred and revenues gained from managing loblolly pine (Pinus taeda) plantations in East Texas for strictly timber production or a combination of timber production and wildlife biodiversity. Management regimes evaluated had varying planting densities, thinning frequency and intensities, prescribed burn intervals, and site indices. Economic analyses used to evaluate management regimes over a range of nonindustrial private landowner (NIPF) alternative rates of return (ARRs) and site indexes were net present worth, land expectation value, and equal annual annuity. These economic analyses demonstrated that altering management …

Wellness And Karate, Cristina Kumpf

Electronic Theses and Dissertations

The promotion of wellness is an integral part of the counseling field and is considered to be a central focus to the counseling process (Barden, Conley, & Young, 2015; Myers, 1992). The counseling profession adopted the concept of wellness because it harmonizes with many of the founding principles of the ACA and is seen as a process of questing toward optimal health and well-being in body, mind, and spirit (Barden, Conley, & Young, 2015; Myers, 1992; Myers, Sweeney, & Witmer, 2000). Additionally, ACA Code of Ethics (2014) state that counselors “engage in self-care activities to maintain and promote their own …

The Effect Of The Movie Time Social Learning Method On The Emotional Inferencing Skills In An Adult With Autism Spectrum Disorder, Jenna Reade

Electronic Theses and Dissertations

Individuals with autism spectrum disorder (ASD) have difficulty finding employment and maintaining social relationships. Professional and personal interactions require individuals to make inferences, or read between the lines. Inferencing is a challenge for individuals with ASD because it requires complex information processing. More specifically, it involves the integration of cognitive and linguistic information. There is a lack of research using complex stimuli to treat inferencing. An A-B-A-B design with one adult with ASD was used to examine the effectiveness of a movie-based method, Movie Time Social Learning(Vagin, 2012), on improving the emotional inferencing skills of one young adult with …

Paving The Way For Merleau-Ponty’S Eye And Mind In Organizational Communication Studies, Johan Bodaski

Electronic Theses and Dissertations

The body is a sense-based medium that creates and interprets organizations. Bodies create organization. An aesthetic theory of organizational communication reveals the significance of the body to the organization. Maurice Merleau-Ponty’s philosophy of aesthetics offers a theory of aesthetic organizational communication that is yet to be developed. Merleau-Ponty’s aesthetic essay on painting, Eye and Mind, describes the body as the medium through which painters turn the world into painting. His philosophy of painting builds bridges between aesthetics, the body, and organizational communication.

In chapter one, four theories of organizational communication are described: communication constitutes organization (CCO), text/interpreter, ventriloquism, and …

Effects Of Natural Antioxidants On Motor And Cognitive Deficits In An Animal Model Of Aging And Obesity And Dopaminergic-Like Sh-Sy5y Cell Line, Sneha Potdar

Electronic Theses and Dissertations

Aging is a universal phenomenon. One of the greatest challenges faced by the elderly population is to sustain a healthy standard of living. Advancing age is associated with increased motor and cognitive deficits. Loss of balance, falls, hip fractures, and poor memory all contribute to a decline in the quality of life of the aging population. While ongoing research is making advances to find therapeutic interventions for neurodegenerative disorders like Parkinson’s and Alzheimer’s diseases, there is a pressing need to address deficits associated with normal aging.

Increase in oxidative stress and a decline of antioxidant mechanisms with aging have been …

The Zombie Apocalypse Has Already Happened: Queering Subjectivity In Zombie Film, Jessica Dunn

Electronic Theses and Dissertations

This dissertation traces the encounter between psychology as a human science and the viral zombie film genre using the collaborative works of Deleuze and Guattari in conjunction with the queer anti-humanist theories of Colebrook and Halberstam. I interwove thematic (i.e. plot, dialogue, character development) and cinematographic (i.e. shot composition, editing, lighting, musical score) analyses of fourteen viral zombie films with theoretical arguments regarding the deterritorialization of the human subject and its relevance to psychology as a human science. The films were selected from the plethora of viral zombie films released after the turn of the 21st century. The selection was …

The Effectiveness Of Best Management Practices On Water Quality In The Attoyac Bayou Watershed Of East Texas, Cheryl Scott

Electronic Theses and Dissertations

In the Attoyac Bayou Watershed Protection Plan, best management practices (BMPs) were developed for livestock, wildlife, and on-site sewage facilities (OSSFs), using bacteria source tracking (BST), spatially explicit load enrichment calculation tool (SELECT) model, as well as a cost benefit analysis. An evaluation of these BMPs was conducted on the Attoyac Bayou (AB), Big Iron Ore Creek (BIO), Naconiche Creek (NC), Terrapin Creek (TC), and Waffelow Creek (WC) to see if they were meeting their designated use criteria for elevated Escherichia coli (E. coli). Water quality parameters were monitored for five sample locations within the Attoyac Bayou Watershed during March …

The Effects Of Power And Religiously Motivated Ingroup Preference On Social Affiliation, Hernan Escobar

Electronic Theses and Dissertations

Human beings are fundamentally social animals motivated by a need to establish and maintain close social relationships. The creation of these relationships inevitably leads to the creation of groups, along with a desire for power as a method of determining how resources are to be allocated within these groups. Most groups are characterized by individuals who belong to the ingroup and those who are relegated to an outgroup, and one powerful motivator of ingroup favoritism is religious affiliation. Although research has shown that feelings of low power increase the drive to socially affiliate, research has not yet explored how religious …

Breeding Bird Response To Post Oak Savanna Restoration Seven Years Post Management In Eastern Texas, Courtney Mcinnerney

Electronic Theses and Dissertations

Oak savannas were once an abundant vegetation type in the Midwestern United States that have now declined to <1% of their original distribution. Historically, natural disturbances such as periodic fire and grazing maintained oak savannas, but these have been reduced or eliminated, resulting in woody encroachment and subsequent habitat loss and degradation. In 2009-10, a baseline, pre-restoration study was completed to determine vegetation characteristics, breeding bird abundances, nest success, and nest site selection at the Gus Engeling Wildlife Management Area (GEWMA) in eastern Texas. The results showed a lack of savanna vegetation structure on degraded sites and few savanna or grassland obligate bird species. The goal of this study was to determine how breeding birds of oak savanna vegetation types in eastern Texas respond to restoration effects 7 years after initial management. Post-restoration surveys completed in 2016-17 showed a change in avian assemblages from a more woodland dominated community to grassland/savanna community. The presence and breeding of savanna obligate species dickcissel (Spiza americana) and lark sparrow (Chondestes grammacus) indicates that the restoration was successful. The presence of savanna species can be linked to the herbaceous vegetation that was restored to more closely resemble historic oak savanna structure and can quantify the success of restoration efforts.

Performance Evaluation Of Logistic Regression, Linear Discriminant Analysis, And Classification And Regression Trees Under Controlled Conditions, Cahit Polat

Electronic Theses and Dissertations

Logistic Regression (LR), Linear Discriminant Analysis (LDA), and Classification and Regression Trees (CART) are common classification techniques for prediction of group membership. Since these methods are applied for similar purposes with different procedures, it is important to evaluate the performance of these methods under different controlled conditions. With this information in hand, researchers can apply the optimal method for certain conditions. Following previous research which reported the effects of conditions such as sample size, homogeneity of variancecovariance matrices, effect size, and predictor distributions, this research focused on effects of correlation between predictor variables, number of the predictor variables, number of …

Play And Exhibitions: Expanding Definitions Within Museums, Helena Sizemore

Electronic Theses and Dissertations

This thesis is an exploration of the utilization of play, as a method for visitor engagement, within the context of the museum. Play, as a method for learning and engagement, is often a contested topic between scholars and practitioners within the museum field. This is in part due to the ambiguous nature of defining play, the ever-present dichotomy between work and play, and the struggles museums find in balancing education and entertainment. The Denver Museum of Nature and Science in Denver, Colorado names play as part of one of its core values. Using anthropological theoretical and methodological approaches, I examine …

How Colonization Impacts Identity Through The Generations: A Closer Look At Historical Trauma And Education, Michelle Garcia-Olp

Electronic Theses and Dissertations

Through the lived experiences of 26 New Mexicans, this inquiry investigates how colonization impacts identity through the generations, particularly looking at historical trauma and education. The findings demonstrate the importance of decolonizing spaces within educational settings. Furthermore, the findings demonstrate the need for viewing educational systems and spaces through a Tribal Critical Race Theory (TribalCrit) and Indigenous Storywork lens that lead Indigenous students in finding face (one’s identity), finding foundation (one’s greatest potential/full expression) and finding heart (one’s flow with the creator). The lens of TribalCrit enables the creation of a space where Indigenous students are empowered by their educational …

Sexual Assault And Health: Understanding The Interplay Of Trauma-Related Appraisals And Physical Health Outcomes, Kerry Lyn Gagnon

Electronic Theses and Dissertations

Women who have been sexually assaulted are at risk for negative mental and physical health outcomes; however, limited research has tested how psychological responses to sexual assault may influence physical health. The present study tested a longitudinal model examining the association between posttrauma appraisals and physical health problems. Drawn from a larger study, the sample included 156 ethnically diverse women who had been sexually assaulted within the last year. The study used cross-lagged panel models to test for reciprocal relationships between posttrauma appraisals and physical health problems over time. A secondary aim of the study was to test whether other …

Macromolecule Loading On Plga Particles Through Surface Adsorption, Yiwei Wang

Electronic Theses and Dissertations

The advent of biotherapeutics have impacted the ways in which diseases are treated. In many instances development of recombinant proteins and oligonucleotides into therapeutics are slowed by poor stability of the candidate drugs. Progress has been made in using polymeric particles as carriers of macromolecule drugs. Historically the method is to encapsulate biological drugs into spherical polymeric matrices. Owing to its biocompatible and biodegradable nature, poly (d,l-lactic-co-glycolic acid) (PLGA) has been used extensively in formulating biological drugs into nano- and micro-sized particles. The development of PLGA biologic formulations, however, has been hampered by matrix acidification; the hydrolysis of the polymer …

Cannabidiol Alters The Immune Response To Porphyromonas Gingivalis In Mice., Shilpa Singh

Electronic Theses and Dissertations

Background: Porphyromonas gingivalis is an important etiologic agent of chronic periodontitis, an infectious disease defined by destruction of supporting tissues of the teeth. Marijuana is a risk factor for chronic periodontitis, although underlying mechanisms are poorly understood. As phytocannabinoids have been ascribed antiinflammatory properties, we hypothesized that cannabidiol exposure would lead to altered immune response to P. gingivalis infection facilitating bacterial persistence and, subsequently, increased alveolar bone loss in cannabidiol (CBD)-exposed mice. Methods: P. gingivalis-infected cannabinoid receptor 2 (CB2) knockout and wild type C57/Bl6 mice were exposed, or not exposed, to cannabidiol. Oral swabs from mice were used to monitor …

Uncertain Certainties: An Analysis Of The American Response To The 2014-2016 West African Ebola Epidemic., Kelly Carty

Electronic Theses and Dissertations

This project examines the construction of scientific facts surrounding the 2014-2016 West African Ebola outbreak as well as the subsequent uptake and transformation of those facts by the United States government. While the Ebolavirus ravaged the communities of Sierra Leone, Liberia, and Guinea, the incidence of the virus in other countries was very low. Nonetheless, the United States spent $576 million on domestic preparedness and response. This study addresses this mismatch in the context of the reinvigorated interest among rhetoricians into writing and science. Applying and expanding the methodology of Jeanne Fahnestock, this study analyzes Ebola-related statements in scientific articles, …

Wnt/Β-Catenin Mediated Cancer Stem Cell Activation In Hepatocellular Carcinoma., Harshulkumar M. Pandit

Electronic Theses and Dissertations

Hepatocellular carcinoma (HCC) is one of the deadliest cancers, with variable presentation, high chemotherapy resistance and early tumor recurrence. In this dissertation, we have systematically enriched, identified and characterized HCC cancer stem cells (CSCs) from 3 different HCC cell lines (Hepa1-6, HepG2, and Hep3B) using in vitro serum-free culture method. Enriched spheroids acquired CSC properties, primarily self-renewal capability, spheroid formation ability, and drug resistance. Heterogeneous CSCs enriched from Hepa1-6 cells demonstrated higher tumor initiation and proliferation capability in vivo, compared to control HCC cells in orthotopic immunocompetent mouse model. EpCAM+ CSCs were significantly enriched within heterogeneous Hepa1-6 CSC spheroids. Consequently, …

A Cancer-Targeted Gold Nanoparticle-Based Mri Contrast Agent., Nagwa El-Baz

Electronic Theses and Dissertations

In oncology, imaging plays a major role in terms of early detection and treatment of most types of cancer. Magnetic resonance imaging (MRI) is mostly used for cancer diagnosis due to its excellent contrast resolution. However, MRI for cancer diagnosis is somewhat limited by its sensitivity. In this thesis, we assessed the ability of theranostic platform consisting of gold nanoparticles functionalized with a cancer targeting aptamer; AS1411 and gadolinium chelate (Dotarem thiol derivative; Gd (III)-DO3A) as a MRI contrast agent to target malignant tumors by enhancing the MRI contrast of the detected tumor. The proposed technology is a novel injectable …

A Novel Fibroblast Growth Factor 1 Variant Reverses Nonalcoholic Fatty Liver Disease In Type 2 Diabetes., Qian Lin

Electronic Theses and Dissertations

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder and is strongly associated with type 2 diabetes (T2D). Our recently engineered FGF1 partial agonist, carrying triple mutations (FGF1^△HBS) exhibits greatly reduced proliferative potential, while preserving the full metabolic activity of wild-type FGF1. This study tests the preventive and therapeutic effects of FGF1^△HBS on NAFLD in db/db T2D and explores potential mechanisms. The results showed that administration of FGF1^△HBS to 2-month-old db/db mice for 2 months constantly lowered blood glucose levels, improved insulin sensitivity, and lowered liver weight, lipid deposition, and …

Unfolded Protein Response Pathways In Skeletal Muscle Homeostasis., Kyle R. Bohnert

Electronic Theses and Dissertations

Skeletal muscle mass, contractile properties, and metabolic function are regulated through the coordinated activation of multiple intracellular signaling pathways and genetic reprogramming. The endoplasmic reticulum (ER) plays a pivotal role in protein folding and calcium homeostasis in many cell types, including skeletal muscle. Disruption of calcium levels or accumulation of misfolded proteins in the ER lumen leads to stress, which results in the activation of a signaling network called the unfolded protein response (UPR). Further, recent studies have suggested that in certain conditions, UPR pathways can be activated independent of ER stress. However, the role of ER stress and the …

Investigating The Impact Of Nrmt1 Cancer Mutants On Catalytic Specificity And The Dna Damage Response., Kaitlyn Marie Shields

Electronic Theses and Dissertations

Protein methylation is an established and critical posttranslational modification controlling multiple cellular events. Alterations in protein methylation have been implicated in many diseases, including cancer. My work focused on the N-terminal trimethylase NRMT1 and the N-terminal monomethylase NRMT2. Previous work proposed that NRMT2 assists NRMT1 by priming its substrates for trimethylation. Importantly, NRMT1 mutations have been found in cancers, and loss of NRMT1 has been shown to promote oncogenic phenotypes in cancer cells. Together, this suggests that altered activities of NRMT1/2 may play a role in cancer progression. Although NRMT1/2 are 50% identical, they differ in key aromatic residues in …

Organization And Development Of Cholinergic Input To The Mouse Visual Thalamus., Guela Sokhadze

Electronic Theses and Dissertations

Cholinergic signaling plays a vital role in modulating the flow of sensory information through thalamic circuits in a state-dependent manner. In the dorsal lateral geniculate nucleus (dLGN), the thalamic visual relay, release of acetylcholine (ACh) contributes to enhanced thalamocortical transfer of retinal signal during behavioral states of arousal, wakefulness, and sleep/wake transitions. Moreover, ACh modulates activity of the thalamic reticular nucleus (TRN), a structure which provides inhibitory input to dLGN. While several cholinergic nuclei have been shown to innervate dLGN and TRN, it is unclear how projections from each area are organized. Furthermore, little is known of how or when …
