Effects of Conditional Discrimination Training on Symmetry and Semantic Priming
Psychologists interested in the study of language find that people are faster at making decisions about words that are related than they are at making decisions about words that are not related – an effect called semantic priming. This phenomenon has largely only been document in laboratory settings using natural languages as contest and real words as stimuli. The current study explores the relation between the semantic priming effect and a laboratory procedure designed to give rise to performances that can be described as linguistic. Six adult participants learned to partition a collection of eight stimuli into two sets of four stimuli. Following this, the subjects showed the semantic priming effect within a set of stimuli but not across sets. These data suggest that it may be possible to study linguistic phenomenon in laboratory-based procedures allowing better control and the ability to ask very precise questions about linguistic functioning.

Limiting Disability Post-Brain Injury Through a Physical Activity Centered Education Program
Brain injury (i.e., traumatic brain injury, stroke) is a considerable public health issue due to complicated outcomes of the injury, increasing incidence, and high costs linked with medical treatment. Rehabilitation centers are challenged to help individuals manage the resultant associated conditions and prevent secondary and chronic conditions. Research has shown that health promotion programs (HPP) that incorporate education about physical activity (PA) are one mode of rehabilitation that can improve the health of individuals with disabilities. However, PA is not included in the rehabilitation program for individuals with a brain injury, indicating a gap in the services provided. Consequently, the purpose of this study was to create and implement a physical activity centered education (PACE) program within an outpatient rehabilitation program. PACE consisted of an 8-week (16 session) program which aimed to (1) increase PA self-efficacy, (2) increase intention to change PA behaviors, (3) increase amount of PA completed regularly, and (4) promote positive rehabilitation outcomes. Based on previous research it was hypothesized that participation in PACE would result in (1) increased PA self-efficacy, (2) forward progression in intention to change PA behaviors, (3) increased amount of PA completed, and (4) improved rehabilitation outcomes (i.e., abilities, adjustment, participation). The PACE …

Organizational Perspectives of Faculty and Administrators in a Southwest Community College District
This quantitative study analyzed data from ModernThink’s Best Places to Work survey to describe if employees of different ethnic groups in a community college district held similar or different perspectives on aspects of the work place. ModernThink’s survey describes the perspectives of employees from the view of the individual, the workgroup, and the organization on the competencies of organizational: leadership, communication, respect, and alignment. The study analyzed responses from 457 faculty and administrators to describe workplace perspectives across the district, at seven campuses, and by ethnic group. The results revealed that the employee workgroup was neutral in its perceptions of both the perspectives and competencies for the district; by ModernThink’s criteria the district was not a best place or a poor place to work. Based on the overall responses, four campuses rated as a best place to work; three campuses were rated as neutral. Of the perspectives, one campus rated best in all three factors and two campuses rated best on two of three factors. Rating variations between the two ethnic groups were minimal across the district and only diverged at two of the seven campuses. Although the study did not examine campus culture or climate, the findings suggest that …

Coaches’ Influence on Male Adolescents’ Achievement Motivation, Psychological Factors, and Sport Participation
The motivational climate, as created by coaches, and athletes’ goal orientations are key constructs in understanding children’s experiences with sport. In this study, the relationship between the perceived motivational climates, male adolescents’ goal orientation, and their experiences of self-esteem, sport competence, enjoyment, and ultimately, intention to continue participating in sport was examined. Participants were 405 male adolescents (Sample A: n = 200; Sample B: n = 205) aged 13-15 years old. Structural equation modeling indicated an overall good fit to the structural model for both data sets. A task goal orientation was predicted by higher levels of coach-created task climate. Participants with higher task goal orientation had greater sport competence, self-esteem, and more enjoyment in sport; enjoyment was the only significant predictor of their intention to continue playing the sport they believe is most important over the next three years.

Relationship of Alpha-Theta Amplitude Crossover during Neurofeedback to Emergence of Spontaneous Imagery and Biographical Memory
I obtained 182 session graphs from 10 client records from a university-based neurotherapy clinic and from a private practitioner. These graphs were used to examine the relationship of therapeutic crossover activity (defined as at least 3 minutes in duration and at least 1μv in amplitude) with and without predetermined amplitude thresholds of beta (15-20Hz) to client reports of imagery and to treatment outcomes. Crosstab analysis revealed that significantly more reports of imagery were observed in the therapeutic crossover with beta condition and that higher amplitudes of slower brainwave activity correlated with progression to deeper states of consciousness. Multi-level modeling revealed a significant interaction between therapeutic crossover activity, higher beta frequency amplitude, and reported salient imagery. Due to small sample size, significance testing was not deemed appropriate. However, observation in change of pre-post scores suggested that individuals who experienced more therapeutic crossover with sufficient beta amplitude conditions had greater improvements on post-test measures (BAI, BDI, BHS, PSQI and MMPI) than those with no or few crossovers. Higher amplitudes of slower brainwave activity correlated with progression to deeper states of consciousness, with delta amplitude positively correlating with transpersonal states. Reports of imagery and/or biographical memory are much more likely to occur during …

A Boy in a Canoe
The dissertation consists of a collection of personal essays about hunting and fishing. Because the essays are narratives and contain dialogue, characterization, description, themes, etc., they fall under the genre of creative nonfiction. The dissertation has two parts. Part I consists of an essay that discusses the author’s struggle to combine creative nonfiction with outdoor writing and also describes the author’s dilemma of writing about hunting, a topic that is often controversial at the university, while a graduate student. Part II of the dissertation consists of narratives that recount the author’s hunting and fishing experiences that occurred in North Texas and in the mountains of New Mexico. The essays discuss fishing for trout and hunting for deer, wild boars, quail, and duck. Three major themes are developed throughout the dissertation. The first theme describes the close relationship that exists between the author and his father. This closeness is partly due to the time that they have shared during decades of hunting and fishing together. The second theme discusses the ethics of hunting and especially focuses on which methods of hunting are ethical and which methods are not. The third theme explores the complex and sometimes unpleasant interactions that occur between …

Gentrification in Oklahoma City: Examining Urban Revitalization in Middle America
Gentrification applies not only to the largest and oldest cities; it is a multi-scalar phenomenon playing out in smaller and less prominent settings as well. This study examines temporal changes in property values, demographic characteristics, and types of businesses in the central Oklahoma City area. A major urban revitalization project which began in 1993 created strong gentrification characteristics near the renewal's epicenter, the Bricktown entertainment district. Data suggest that several specific neighborhoods in the surrounding area exhibited rising property values, improving educational attainment rates, decreasing household sizes, and a shift toward cosmopolitan retail activity. While it is evident that Bricktown has been transformed, the socio-economic traits of surrounding neighborhoods have been altered by the ripple effects of urban renewal.

The Development of Disordered Eating Among Female Undergraduates: A Test of Objectification Theory
Objectification theory (Fredrickson & Roberts, 1997) has been used to explain how mechanisms related to socialization, sexual objectification, and psychological variables interact to predict mental health difficulties. Among a sample of 626 undergraduate women (age 18-24), this study empirically tested components of Moradi and Huang’s (2008) model and extended it by including additional socialization experiences (i.e., sexual abuse, societal pressures regarding weight and body size). Structural equation modeling analyses suggested that the model provided a good fit to the data and the model was tested in the confirmatory sample. Across the two samples, high levels of Body Shame and low levels of Internal Bodily Awareness directly led and high levels of Societal Pressures Regarding Weight and Body Size, Internalization of Cultural Standards of Beauty, and Self-objectification indirectly led to increased Bulimic Symptomatology and accounted for 65 to 73% of the variance in Bulimic Symptomatology. A history of sexual abuse and sexual objectification were not consistently supported within the model and do not appear to be as salient as the experience of societal pressures regarding weight and body size in understanding women’s experience of bulimic symptomatology. Implications for practice and future research are discussed.

Soil and Forest Variation by Topography and Succession Stages in the Greenbelt Corridor, Floodplain of the Elm Fork of the Trinity River, North Texas.
The Greenbelt Corridor (GBC), located in a floodplain of the Elm Fork of the Trinity River, contains patches of bottomland forest and serves as part of Lake Lewisville’s flood control backwaters. This study examines forest structure and composition in relation to topographic position and forest stage in the GBC. Thirty two plots were surveyed within various stage classes, topographic positions, and USDA soil types. Trees were identified and measured for height and DBH. Density, basal area, and importance value for each of species was calculated. Soil and vegetation were analyzed using ANOVA, Principal Component Analysis, Canonical Correlation, Canonical Correspondence Analysis and Cluster Analysis. Tests confirmed that calcium carbonate and pH show significant differences with topographic positions but not with forest stage. Potassium shows no significant difference with soil texture class. Sand shows a strong negative correlation with moisture, organic matter, organic carbon and negative correlation with calcium carbonate and potassium. Silt shows positive correlation with moisture, organic matter, organic carbon, and calcium carbonate. Clay shows strong positive correlation with moisture, organic matter and organic carbon but negative correlations with pH. Swamp privet is dominant tree types in wetland forest. Sugarberry cedar elm, green ash and American elm are widely distributed …

High Risk Occupations: Employee Stress and Behavior Under Crisis
The purpose of this study is to analyze the relationships between stress and outcomes including organizational citizenship behavior (OCB), job satisfaction, and burnout in high-risk occupations. Moreover, how personality, emotions, coping, and leadership influence this relationship is investigated. Data were collected from 379 officers in 9 police organizations located in the Southern and Southwest United States. The primary research question addressed within this dissertation is: What is the relationship between stress and behavioral and affective outcomes in high-risk occupations as governed by coping, leadership, and crisis? The majority of the hypothesized relationships were supported, and inconsistencies center on methodological and theoretical factors. Findings indicate that occupational stressors negatively influence individuals in high-risk occupations. Moreover, crisis events exacerbate these influences. The use of adaptive coping strategies is most effective under conditions of low stress, but less so under highly stressful circumstances. Similarly, transformational leader behaviors most effectively influence how individuals in high-risk occupations are affected by lower, but not higher levels of stress. Profiles of personality characteristics and levels of emotional dissonance also influence the chosen coping strategies of those working in high-risk occupations. Prescriptively, it is important to understand the influences among the variables assessed in this study, because negative …

Design and Implementation of Broad Band and Narrow Band Antennas and Their Applications
The thesis deals with the design and implementation of broadband and narrowband antennas and their applications in practical environment. In this thesis, a new concept for designing the UWB antenna is proposed based on the CRLH metamaterials and this UWB antenna covers a frequency range from 2.45 GHz to 11.6 GHz. Based on the design of the UWB antenna, another antenna is developed that can cover a very wide bandwidth i.e from 0.66 GHz to 120 GHz. This antenna can not only be used for UWB applications but also for other communication systems working below the UWB spectrum such as GSM, GPS, PCS and Bluetooth. The proposed antenna covering the bandwidth from 0.66 GHz to 120 GHz is by far the largest bandwidth antenna developed based on metamaterials. Wide band antennas are not preferred for sensing purpose as it is difficult to differentiate the received signals. A multiband antenna which can be used as a strain sensor for structural health monitoring is proposed. The idea is to correlate the strain applied along the length or width with the multiple resonant frequencies. This gives the advantage of detecting the strain applied along any direction (either length or width), thus increasing the …

Reliability and Validity of the FITNESSGRAM® Physical Activity Items
Large-scale assessments of children and youth physical activity (PA) behaviors are regularly conducted in school settings. In addition to assessing actual fitness, the FITNESSGRAM® assesses self-reported PA behaviors for aerobic, strengthening, and flexibility activity within the past 7 days. The purpose of this study was to examine the reliability and validity of the three PA items. Participants included 1010 students in grades three through twelve and were either tested under a teacher – teacher condition, an expert - expert condition, a teacher – expert condition, or a trained teacher – expert condition. Comparisons of the responses to the PA items indicated adequate reliability for teachers, but the reliability improved with training. Likewise, the validities for teachers are moderate to fair; however, they improved when teachers received additional training.

Influences on Grief Among Parentally Bereaved Adults
The parent-child relationship is significant throughout the life course, although both positive and negative changes occur as children reach adulthood and develop an identity independent of their family of origin. Grief resulting from parental loss during this time may be a product of many variables including age, relationship quality, and sex roles. The current study examined several variables potentially influencing grief after the death of a parent. As part of a larger study, adults (n = 180) completed measures assessing parental involvement, personal grief and adjustment, as well as sex role preferences. The archival data were subjected to analyses of covariance, taking into account time since the death and children’s sex role preferences (traditional or egalitarian). Female sex of the child was significant in predicting several aspects of grief, suggesting that women have a stronger emotional experience of grief. This may be a result of young women’s stronger emotional bonds with parents when compared to men, feelings of exclusion from college peers during bereavement, or vulnerability for rumination. Sex role preferences were also influential in several aspects of grief. Sex of the parent was not significant, although the interaction for sex of the parent and sex of the child was, …

Posttraumatic Growth: Behavioral, Cognitive, and Demographic Predictors
Recent trauma research argues trauma results in distinct positive and negative consequences, however; many trauma variables positively correlate with both outcomes. This study examined posttraumatic growth (PTG) and post-traumatic stress disorder (PTSD) symptoms as positive and negative trauma outcomes. Behavioral, cognitive, and demographic correlates and predictors were assessed to help clarify differences between the two outcomes. While several behavioral factors were common to both PTG and PTSD symptoms, centrality of event and problem focused coping were the strongest PTG predictors, whereas centrality of event and avoidant coping were the strongest PTSD predictors. These findings indicate while greater incorporation of a trauma/stressful event into one’s identity is a key component of both PTG and PTSD development, behavioral response may be a determining factor between growth or debilitation.

Identifying the Physical Activity Needs of Outpatients with a Traumatic Brain Injury
Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment – emphasizing the need for effective rehabilitation programs. One mode of rehabilitation that has been demonstrated to improve health and reduce healthcare costs is health promotion programs (HPPs) that incorporate physical activity (PA). However, PA is not currently incorporated into the standard of care post-TBI. The purpose of this study was to conduct group interviews among individuals with a TBI undergoing outpatient rehabilitation to determine PA knowledge, attitudes, intentions, and barriers. Results will be used to develop a HPP that focuses on facilitating PA participation as part of the rehabilitation process. Seventeen participants completed a series of group interviews (2-3 people/group) regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through triangulation of data (i.e., theoretical underpinning; multiple researchers and data-coders). A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (1) an inability to differentiate between PA and physical therapy, (2) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (3) an interest in participating in a PA HPP as part of their rehabilitation. …

Scene Analysis Using Scale Invariant Feature Extraction and Probabilistic Modeling
Conventional pattern recognition systems have two components: feature analysis and pattern classification. For any object in an image, features could be considered as the major characteristic of the object either for object recognition or object tracking purpose. Features extracted from a training image, can be used to identify the object when attempting to locate the object in a test image containing many other objects. To perform reliable scene analysis, it is important that the features extracted from the training image are detectable even under changes in image scale, noise and illumination. Scale invariant feature has wide applications such as image classification, object recognition and object tracking in the image processing area. In this thesis, color feature and SIFT (scale invariant feature transform) are considered to be scale invariant feature. The classification, recognition and tracking result were evaluated with novel evaluation criterion and compared with some existing methods. I also studied different types of scale invariant feature for the purpose of solving scene analysis problems. I propose probabilistic models as the foundation of analysis scene scenario of images. In order to differential the content of image, I develop novel algorithms for the adaptive combination for multiple features extracted from images. I …

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries
Cosmology, as an all-encompassing theoretical construction of universal reality, serves as one of the best indicators for a variety of philosophical, scientific, and cultural values. Within any cosmological system, the question of extraterrestrial life is an important element. Mere existence or nonexistence, however, only exposes a small portion of the ideological significance behind the contemplation of life outside of earth. The manners by which both believers and disbelievers justify their opinions and the ways they characterize other worlds and their inhabitants show much more about the particular ideas behind such decisions and the general climate of thought surrounding those who consider the topic. By exploring both physical and abstract structures of the universe, and specifically concepts on the plurality of worlds and extraterrestrial life, Western European thought in the seventeenth and eighteenth centuries reveals not an era of pure advancement and modernization, but as a time of both tradition and change.

Effects of CFT Legumine™ Rotenone on Macroinvertebrates in Four Drainages of Montana and New Mexico
Rotenone is considered essential in the restoration of native fish populations; however, the technique is contentious and criticized, specifically concerning impacts to invertebrates. Knowledge of effects to non-target organisms is important for the management and conservation of fish populations. This thesis has two general objectives: (1) demonstrate the influence CFT Legumine™ rotenone has on benthic macroinvertebrates for restoration projects in Montana and New Mexico and (2) evaluate the immediate response by means of invertebrate drift. Chapters 2 and 4 incorporate results from four different restoration projects that examine benthic macroinvertebrate response. Results indicate treatment effects are minimal for Specimen and Cherry Creek projects in Montana. New Mexico projects, Comanche and Costilla Creek suggest a greater influence. Potassium permanganate used to neutralize rotenone, influenced communities in three of the four projects. Regardless, invertebrates in all four projects recovered one-year after treatment. Chapter 3 examines macroinvertebrate drift during rotenone treatment. Results suggest a delayed response compared to previous literature. Rotenone appears to have the greatest immediate influence on the early life stages of Ephemeroptera and Plecoptera. To reduce impacts of rotenone to invertebrates, managers should apply CFT Legumine and use the minimal dosage and duration to complete the projects goal of removing …

Mikrokosmos and 32 Piano Games: Introducing Contemporary Musical Language and Developing Piano Technique for the Beginning Student
As new musical styles have emerged in the twentieth century with characteristic sounds, chords, forms, meters, and intervals, teachers need to broaden and re-define the way they introduce musical concepts to beginning piano students. The purpose of this study is to offer different instructional possibilities aside from conventional methods of teaching beginning pianists. This is accomplished through a comparison of the two different approaches of the Hungarian composer Béla Bartók and the American composer Ross Lee Finney. Bartók’s Mikrokosmos, a graded set of 153 pieces, and Finney's 32 Piano Games are examined through this paper.

Void Growth and Collapse in a Creeping Single Crystal
Aircraft engine components can be subjected to a large number of thermo-mechanical loading cycles and to long dwell times at high temperatures. In particular, the understanding of creep in single crystal superalloy turbine blades is of importance for designing more reliable and fuel efficient aircraft engines. Creep tests on single crystal superalloy specimens have shown greater creep strain rates for thinner specimens than predicted by current theories. Therefore, it is necessary to develop a more predictive description of creep processes in these materials for them to be used effectively. Experimental observations have shown that the crystals have an initial porosity and that the progressive growth of these voids plays a major role in limiting creep life. In order to understand void growth under creep in single crystals, we have analyzed the creep response of three dimensional unit cells with a single spherical void under different types of isothermal creep loading. The growth behavior of the void is simulated using a three dimensional rate dependent crystal plasticity constitutive relation in a quasi-static finite element analysis. The aim of the present work is to analyze the effect of stress traixiality and Lode parameter on void growth under both constant true stress and …

Missing Data Treatments at the Second Level of Hierarchical Linear Models
The current study evaluated the performance of traditional versus modern MDTs in the estimation of fixed-effects and variance components for data missing at the second level of an hierarchical linear model (HLM) model across 24 different study conditions. Variables manipulated in the analysis included, (a) number of Level-2 variables with missing data, (b) percentage of missing data, and (c) Level-2 sample size. Listwise deletion outperformed all other methods across all study conditions in the estimation of both fixed-effects and variance components. The model-based procedures evaluated, EM and MI, outperformed the other traditional MDTs, mean and group mean substitution, in the estimation of the variance components, outperforming mean substitution in the estimation of the fixed-effects as well. Group mean substitution performed well in the estimation of the fixed-effects, but poorly in the estimation of the variance components. Data in the current study were modeled as missing completely at random (MCAR). Further research is suggested to compare the performance of model-based versus traditional MDTs, specifically listwise deletion, when data are missing at random (MAR), a condition that is more likely to occur in practical research settings.

Synthetic Cannabinoid Usage among College Students: The Example of K2 and Spice
The primary goal of this study was to investigate the awareness and prevalence of Spice and K2 usage among a population of college students, as well as the demographics of such users. The study also sought to determine whether or not students prefer these products over natural cannabis, in addition to examining the most popular methods of obtainment and the most commonly reported side effects of K2 and Spice usage. Participants consisted of 643 undergraduate students enrolled at the University of North Texas during the fall 2011 semester. Findings indicate that while students exhibit a relatively high awareness of K2 and Spice, usage of these products is not a prevalent occurrence. Implications of the findings are discussed.

Type D Personality and Coping Style as Predictors of Cardiovascular Risk
Although cardiovascular disease (CVD) does not occur until mid to late life for most adults, the presence of risk factors for CVD, such as high blood pressure (BP) and high cholesterol, has increased dramatically in young adults. Type D personality consists of two personality traits, negative affectivity (NA) and social inhibition (SI), and has repeatedly been shown to be an independent predictor of hard medical outcomes (e.g. morbidity and mortality) in cardiac patients. The present study examined the relationships between Type D personality (high NA and high SI), coping strategies, and physiological markers of cardiovascular health in a sample of non-medical, university students. Measures of cardiovascular risk included high frequency heart rate variability (HF HRV), calculated LDL cholesterol, and systolic blood pressure (SBP). Regression analyses revealed that higher use of social supportive coping was a significant predictor of calculated LDL cholesterol. Social supportive coping was also shown to moderate the relationship between Type D personality and HF HRV. Interventions that target psychological and physiological mechanisms associated with CVD are well developed. Clear identification of young adults who are at risk of developing CVD is necessary to intervene in a manner that could potentially save lives. Additional systematic research, especially if …
