Testing a Comprehensive Model of Muscle Dysmorphia Symptomatology in a Nonclinical Sample of Men
As increasing emphases are placed on the importance of a muscular male physique in Westernized culture, more men are experiencing eating, exercise, and body image (EEBI) disturbances. Clinician-researchers have identified a syndrome, termed muscle dysmorphia (MD), in which individuals, usually men, are pathologically preoccupied with their perceived lack of muscularity. The current study tested a modified version of an extant theoretical model of MD symptomatology as well as an alternative model of MD symptomatology. Over 700 adult men completed a demographic questionnaire, a symptom inventory, a self-esteem questionnaire, a measure of perfectionism, a measure of the media’s influence on EEBI disturbances, and measures of body dissatisfaction and MD symptoms. Structural equation modeling (SEM) was used to examine the goodness of fit of the proposed models. Overall, the first model demonstrated poor fit with the data. Conversely, the alternative model fit the data adequately. The alternative model was cross validated with a second sample, and also fit this data adequately.

Passionate transformation in vernicle images.
This thesis will examine the iconography of late-thirteenth- through fifteenth-century images of St. Veronica's veil, also known as vernicles. In the late Middle Ages, vernicle iconography changed from iconic representations of Christ's face toward graphic imagery of Christ's suffering during his Passion. These passionate transformations, as I have called them, were affected by the Roman Sudarium relic, popular devotion to Christ's suffering and humanity during his Passion, and the Catholic ritual of Mass. This thesis will consider how the function of vernicle images during Mass was reflected in their iconography throughout Europe between 1250 and 1500.

The Effects of Music Training on Electroencephalographic Coherence of Preschool Children
The purpose of this study was to examine the effects of music training on electroencephalographic (EEG) coherence of preschool children. EEG coherence is a measurement of brain wave activity that reflects anatomical and neurophysiological parameters and functional connectivity between areas of the brain. Participants were 4- to 6-year-old children divided into two groups: one received music training for 20 minutes twice a week for 10 weeks while the other group served as controls. Nineteen channels of EEG data were collected from each child pre- and post-training. Data were collected from three conditions: eyes-open resting, listening to music, and performing the Object Assembly subtest of the Weschler Preschool and Primary Scale of Intelligence - Revised (1989). The hypothesis was that the music training group would show increased EEG coherence as compared to controls. The EEG data was reduced into seven bandwidths and analyzed separately for each condition. Multiple ANCOVAs were used to factor out pre-test variability and to maximize connectivity changes between the two groups. The dependent measures were the post-QEEG electrode pairs and the covariates were the pre-QEEG electrode pairs. Results indicated the eyes-open and listening to music conditions showed more significant changes between the groups than the Object Assembly …

Study of radicals, clusters and transition state species by anion photoelectron spectroscopy
Free radicals, elemental and van der Waals clusters and transition state species for bimolecular chemical reactions are investigated using anion photoelectron spectroscopy. Several low-lying electronic states of ozone have been identified via photoelectron spectroscopy of O{sub 3}{sup {minus}}. A characterization of these states is important to models for atmospheric ozone reaction kinetics. The fluoroformyloxyl radical, FCO{sub 2}, has been investigated, providing vibrational frequencies and energies for two electronic states. The technique has also been employed to make the first direct observation and characterization of the NNO{sub 2} molecule. Several electronic states are observed for this species which is believed to play a role as a reactive intermediate in the N + NO{sub 2} reaction. The experimental results for all three of these radicals are supplemented by ab initio investigations of their molecular properties. The clusters investigations include studies of elemental carbon clusters (C{sub 2}{sup {minus}} {minus} C{sub 11}{sup {minus}}), and van der Waals clusters (X{sup {minus}}(CO{sub 2}){sub n}, X = I, Br, Cl; n {le} 13 and I{sup {minus}} (N{sub 2}O){sub n=1--11}). Primarily linear clusters are observed for the smaller carbon clusters, while the spectra of the larger clusters contain contribution from cyclic anion photodetachment. Very interesting ion-solvent interactions are …

Filial Therapy with Native Americans on the Flathead Reservation
This study was designed to determine the effectiveness of the 10-week filial therapy model as an intervention for Native American parents and their children residing on the Flathead Reservation in Montana. Filial therapy is an approach used by play therapists to train parents to be therapeutic agents with their own children. Parents are taught basic child-centered play therapy skills and practice those skills during weekly play sessions with their children. The purpose of this study was to determine if filial therapy is effective in: 1) increasing parental acceptance of Native Americans residing on the Flathead Reservation of their children; 2) reducing the stress level of those parents; 3) improving empathic behaviors of those parents toward their children; 4) changing the play behaviors of children with their parents who participated in the training; and, 5) enhancing the self-concept of those children. The experimental group parents (N=11) received 10 weekly 2-hour filial therapy training sessions and participated in weekly 30-minute play sessions with one of their children. The control group (N=10) received no treatment during the 10 weeks. All adult participants completed the Porter Parental Acceptance Scale and the Parenting Stress Index. Child participants completed the Joseph Pre-school and Primary Self Concept …

Program Components for a Corporate Wellness Program
This study was to determine if the importance assigned by health educators (judges) to components of corporate health promotion programs is the same as or different from program components most frequently offered by corporations for employees. This involved establishing a list of program components that judges felt were important for wellness programs and comparing this list with programs actually existing in polled corporations. A literature review was used to establish an initial list of program components. Thirty-eight judges returned questionnaires incorporating the list. A Spearman's rho and scattergram were used to test for correlations between judges' opinions and corporate practices. The report concludes that no correlation exists but that there is agreement among the judges polled that corporations should promote employee wellness programs.

A Next-to-Leading-Order QCD Analysis of Neutrino-Iron Structure Functions at the Tevatron
Nucleon structure functions measured in neutrino-iron and antineutrino-iron charged-current interactions are presented. The data were taken in two high-energy high-statistics runs by the LAB-E detector at the Fermilab Tevatron. Structure functions are extracted from a sample of 950,000 neutrino and 170,000 antineutrino events with neutrino energies from 30 to 360 GeV. The structure functions F{sub 2} and xF{sub 3} are compared with the predictions of perturbative Quantum Chromodynamics (PQCD). The combined non-singlet and singlet evolution in the context of PQCD gives value of {Lambda}NLO,(4)/MS = 337 {+-} 28 (exp.) MeV, which corresponds to {alpha}{sub S}(M{sub Z}{sup 2}) = 0.119 {+-} 0.002 (exp.) {+-} 0.004 (theory), and with a gluon distribution given by xG(x,Q{sub 0}{sup 2} = 5GeV{sup 2}) = (2.22 {+-} 0.34) {times} (1 {minus} x){sup 4.65{+-}0.68}.

Preschool Teachers' Self-reported Levels of Preparation for Classroom Behavior Management
Research indicates that serious behavior problems begin during the early childhood years. The study examined the perceived preparedness of teachers related to behavior management as well as preschool teachers' usage of evidence-based prevention and intervention strategies. The data indicates that preschool teachers feel prepared for managing aggression in their classrooms and report utilizing evidence-based prevention and intervention strategies regularly. Additionally, the data shows a weak relationship between teacher variables and the likelihood of feeling prepared for managing aggression or utilizing evidence-based strategies. The results can be used to gain a better understanding of special education preschool teachers' training needs in regard to behavior management and managing behavior problems in the preschool classroom.

A Compton scatter camera for spectral imaging of 0.5 to 3.0 MeV gamma rays
A prototype Compton scatter camera for imaging gamma rays has been built and tested. This camera addresses unique aspects of gamma-ray imaging at nuclear industrial sites, including gamma-ray energies in the 0.5 to 3.0 MeV range and polychromatic fields. Analytic models of camera efficiency, resolution and contaminating events are developed. The response of the camera bears strong similarity to emission computed tomography devices used in nuclear medicine. A direct Fourier based algorithm is developed to reconstruct two-dimensional images of measured gamma-ray fields. Iterative ART and MLE algorithms are also investigated. The point response of the camera to gamma rays of energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms are also investigated. The point response of the camera to gamma rays energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms and produces images that are, in general, of the same quality. Measured images of several phantoms are shown. Important results include angular resolutions as low as 4.4{degrees}, reproduction of phantom …

Teacher Perceptions of Supports that Promote Computer Self-Efficacy and Transformational Digital Pedagogy in One-to-One Learning Environments
Although one-to-one technology programs are rapidly expanding in secondary schools, the literature about how to effectively leverage these programs to improve teaching and learning is relatively small. Little guidance is available for school leaders attempting to improve teachers' willingness and ability to incorporate technology effectively into their instruction. The purpose of this mixed-methods case study was to discovery what supports school leaders provide to promote high levels of computer self-efficacy and transformational digital pedagogies in one-to-one learning environments. Data were collected from English language arts, Social Studies, and science teachers in three high schools in a suburban school district in northeast Texas using an online survey, eight virtual semi-structured interviews, and two virtual focus group interviews. Data were analyzed using descriptive statistics and deductive and inductive analysis. The findings of the study reveal most teachers perceived their ability to effectively deliver digital instruction as strong, and most were able to incorporate technology into their lessons at transformational levels. The following themes emerged from data regarding teachers' perceptions of support: shared vision, realistic and supportive climate, collaboration, encouragement, job-embedded professional learning, continuous improvement, equity, and safe, legal, and ethical use. The findings of this study serve as a foundation for understanding …

The Stabat Mater of Herbert Howells: The Agony and the Ecstasy
Access:
Use of this item is restricted to the UNT Community
Herbert Howells composed three large works for chorus and orchestra: a requiem (Hymnus Paradisi), Latin mass (Missa Sabrinensis) and finally a Stabat Mater. Writings, performances and recordings of the Stabat Mater, however, have been few. As the Stabat Mater is believed to be the culmination of his musical prowess, it is important to bring this major work to light. Chapter 1 begins with a brief introduction to Herbert Howells, then continues as a brief biographical sketch. Howells's life is discussed from birth, as organ scholar, student at the Royal College of Music, his teaching professorship at the same institution, and important compositions by decade until his death. Chapter 2 is an overview of the Hymnus Paradisi and Missa Sabrinensis. The chapter gives historical information on each work, including reasons for commission, dates of composition and performance, orchestration and choral composition, type of soloists, conductor and recordings. Chapter 3 is an in depth study of the Stabat Mater. The chapter includes reasons for the genesis of the work, current and past events that affected the composition, musical influences, and the death of his son Michael Kendrick Howells. A second section to this chapter addresses the text of the Stabat Mater, including …

A Study of the Intent to Fully Utilize Electronic Personal Health Records in the Context of Privacy and Trust
Government initiatives called for electronic health records for each individual healthcare consumer by 2014. the purpose of the initiatives is to provide for the common exchange of clinical information between healthcare consumers, healthcare providers, third-party payers and public healthcare officials.This exchange of healthcare information will impact the healthcare industry and enable more effective and efficient application of healthcare so that there may be a decrease in medical errors, increase in access to quality of care tools, and enhancement of decision making abilities by healthcare consumers, healthcare providers and government health agencies. an electronic personal health record (ePHR) created, managed and accessed by healthcare consumers may be the answer to fulfilling the national initiative. However, since healthcare consumers potentially are in control of their own ePHR, the healthcare consumer’s concern for privacy may be a barrier for the effective implementation of a nationwide network of ePHR. a technology acceptance model, an information boundary theory model and a trust model were integrated to analyze usage intentions of healthcare consumers of ePHR. Results indicate that healthcare consumers feel there is a perceived usefulness of ePHR; however they may not see ePHR as easy to use. Results also indicate that the perceived usefulness of …

Human Rights and the Strategic Use of US Foreign Food Aid
How does respect for human rights affect the disbursement of food aid by US foreign policymakers? Scholars analyzing foreign aid generally look at only total economic aid, military aid or a combination of both. However, for a more nuanced understanding of human rights as a determinant of foreign aid, the discrete foreign aid programs must be examined. By disentangling component-programs from total aid, this analysis demonstrates how human rights influence policymakers by allowing them to distribute food aid to human rights abusing countries. Consequently, policymakers can promote strategic objectives with food aid, while legally restricted from distributing other aid. The primary theoretical argument, which links increasing human rights abuse with increasing food aid, is supported by results from a Heckman model. This procedure models the two-stage decision-making process where foreign policymakers first, select countries for aid and then, distribute aid to those selected.

Fashion-brand Experiences in Multi-channel Retailing: Impacts of Experience Dimensions and Experience Types on Brand Resonance
The brand behind the garment is what gives the product popularity, relevance to the consumer, and overall profitability. As time passes, markets are becoming flooded with more brands that inherently provide the commodities. As a result, fashion marketers must put more time and investment into stipulating ways for which their brand can reach a select target consumer and enhance repeat purchase intentions with their competitive differentiations. As their efforts engage, an experiential perspective emerges in the fashion industry. By comparing fashion brands and their different distribution channels, the objectives of this study are to identify consumers’ perceptions of fashion brand experience dimensions and experience types, and to investigate the effect of brand experience dimensions and types on brand resonance. Upon extending Schmitt and Brakus, Schmitt, and Zarantonello’s experience dimensions and types, in conjunction with Keller’s brand resonance model, 12 out of 20 hypotheses confirm the significant impact of consumers experiences on brand resonance by analyzing the data (n = 374) from a university in the United States. Sensory and affective experiences are primary factors for establishing fashion brand association, while cognitive and relational driven experiences lead to establishing fashion brand loyalty. Sensory, affective, and relational experiences affect both product and …

Carbon doping of III-V compound semiconductors
Focus of the study is C acceptor doping of GaAs, since C diffusion coefficient is at least one order of magnitude lower than that of other common p-type dopants in GaAs. C ion implantation results in a concentration of free holes in the valence band < 10% of that of the implanted C atoms for doses > 10{sup 14}/cm{sup 2}. Rutherford backscattering, electrical measurements, Raman spectroscopy, and Fourier transform infrared spectroscopy were amonth the techniques used. Ga co-implantation increased the C activation in two steps: first, the additional radiation damage creates vacant As sites that the implanted C can occupy, and second, it maintains the stoichiometry of the implanted layer, reducing the number of compensating native defects. In InP, the behavior of C was different from that in GaAs. C acts as n-type dopant in the In site; however, its incorporation by implantation was difficult to control; experiments using P co-implants were inconsistent. The lattice position of inactive C in GaAs in implanted and epitaxial layers is discussed; evidence for formation of C precipitates in GaAs and InP was found. Correlation of the results with literature on C doping in III-V semiconductors led to a phenomenological description of C in …

Eagles Overhead: The History of US Air Force Airborne Forward Air Controllers, from the Muese-Argonne to Mosul
Eagles Overhead provides a critical history of US Air Force Forward Air Controllers and examines their role, status, and performance in the Air Force's history. It begins by examining the US's initial adoption of air power, and American participation in aerial combat during World War I and traces the FACs' contributions to every US Air Force air campaign from the Marne in 1918 to Mosul in 2017. However, since 2001 FACs' contributions have been sporadic. Eagles Overhead asks why, despite the critical importance of FACs, have they not been heavily used on US battlefields since 2001? It examines the Air Force FAC's theoretical, doctrinal, institutional, and historical frameworks in the first nine chapters to assess if the nature of air warfare has changed so significantly that the concept and utility of the FAC has been left behind. Or, has the FAC been neglected since 2001 because the Air Force dislikes the capability as it clouds the service's doctrinal preferences? From these examinations, Eagles Overhead draws conclusions about the potential future of Air Force FACs.

The Solo Compositions for Trumpet of Fisher Aubrey Tull: An Analysis of Structural, Technical, and Stylistic Elements for Performance Preparation, with Three Recitals of Selected Works by Bozza, Fasch, Haydn, Tomasi, and Others
Access:
Use of this item is restricted to the UNT Community
The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988). Histories of each composition are chronicled. An analysis of formal organization and significant style features examines musical structure, harmonic language, rhythmic character, instrumentation, …

Nanoscale chemical and mechanical characterization of thin films:sum frequency generation (SFG) vibrational spectroscopy at buriedinterfaces
Sum frequency generation (SFG) surface vibrational spectroscopy was used to characterize interfaces pertinent to current surface engineering applications, such as thin film polymers and novel catalysts. An array of advanced surface science techniques like scanning probe microscopy (SPM), x-ray photoelectron spectroscopy (XPS), gas chromatography (GC) and electron microscopy were used to obtain experimental measurements complementary to SFG data elucidating polymer and catalyst surface composition, surface structure, and surface mechanical behavior. Experiments reported in this dissertation concentrate on three fundamental questions: (1) How does the interfacial molecular structure differ from that of the bulk in real world applications? (2) How do differences in chemical environment affect interface composition or conformation? (3) How do these changes correlate to properties such as mechanical or catalytic performance? The density, surface energy and bonding at a solid interface dramatically alter the polymer configuration, physics and mechanical properties such as surface glass transition, adhesion and hardness. The enhanced sensitivity of SFG at the buried interface is applied to three systems: a series of acrylates under compression, the compositions and segregation behavior of binary polymer polyolefin blends, and the changes in surface structure of a hydrogel as a function of hydration. In addition, a catalytically active thin …
