Luigi Rossi: Early Baroque Italian Cantatas for the Modern Singer, with Modern Editions of Selected Works
The early baroque songs, or cantatas, of Luigi Rossi (1597-1653) are largely absent from the canon of standard Italian vocal repertory utilized by young singers and voice teachers today. In this document Rossi’s composition style is considered, along with modern edition trends, within the emerging genre of Italian early baroque song. Several of Luigi Rossi’s vocal works — chosen for their simplicity, brevity, dramatic content, and suitability for a young singer — are presented in modern transcriptions for voice and piano. The following document lays the groundwork for the inclusion of Luigi Rossi’s songs in the modern canon of Italian vocal music. Part I provides an introduction to Luigi Rossi and the considerations involved in creating modern editions of early baroque solo vocal music. In Chapter 1, Rossi’s patronage and compositional output are considered along with the reception and dissemination of his works in Italy and France. Chapter 2 of this study explores the historical context and lasting influence of Parisotti’s Arie Antiche, the larger collection from which the ubiquitous Schirmer edition, Twenty-four Italian Songs and Arias of the Seventeenth and Eighteenth Centuries, is drawn. One well-known song that appears in the Schirmer edition is Giulio Caccini’s Amarilli, mia bella. In an effort to illustrate trends in modern editions and performance practice, this song is traced from its first appearance in 1602 through representations in modern anthologies. Chapter 3 considers the practical concerns of modern editors of baroque vocal music – such as performance practice applications, ornamentation, and pedagogical considerations – with respect to the cantatas of Luigi Rossi. Chapter 4 discusses the three cantatas by Luigi Rossi that are presented in Part II as performance editions. digital.library.unt.edu/ark:/67531/metadc84209/
Risk and Resilience Faced by Children of Deployed Service Members
The purpose of this study was to examine the impact of military deployment on children, and the roles that risk and protective factors and parenting stress play in emotional symptoms and behaviors exhibited by children while their parents are deployed. A sample of 143 parents (recruited from all branches of the military) who remained at home while their spouses were deployed completed online self-report questionnaires measuring demographic and background information, child internalizing and externalizing behavior, parenting stress, child adaptability, valuing behavior, family cohesion/environment, and parenting behaviors. The sample primarily consisted of mothers (n = 141) and Caucasian individuals (n = 126), which may limit the generalizability of the findings. Results of the study suggest risk factors including parenting stress, corporal punishment, length of time a parent is deployed, and type of deployment (combat vs. non-combat) were predictive of poorer child outcomes. Protective factors including values consistent behavior, child adaptability, and family cohesion were predictive of better childhood outcomes. Parenting stress served as a mediating variable between the relationship of total risk and child outcomes, while values consistent behavior served as a mediating variable between the relationship of protective factors experienced by children and child outcomes. Military deployments not only impact the service members, but also their families at home. Further study and identification of risk and protective factors faced by military children and families are imperative. Implications of findings are discussed as well as suggestions for future research concerning deployment and impact on military families (e.g. identification and empirical validation of programs to support military families. digital.library.unt.edu/ark:/67531/metadc84206/
Are Alzheimer's Special Care Units Really Special? Effects of Residential Status on Family Members' Perspectives on High Quality Care for their Loved-Ones in Long-Term Care
This analysis of secondary data collected from family members of nursing home residents in North Texas (n = 422) used a mixed methods approach to determine if there is a difference in perspectives on quality care among family members of Alzheimer’s/Dementia Special Care Unit (ADSCU) residents compared to those of non-ADSCU residents. Descriptive content analysis was used identify and condense responses to an open-ended question into four meaningful categories of qualities of care. An independent t-test was employed to determine if there was a difference between family members of ADSCU residents and family members of non-ADSCU residents regarding their rating of their loved-ones’ nursing home on the important qualities of care they identified from the open-ended question. Closed-ended questions were organized into indices of these qualities of care, and ordinary least square regression was employed to determine if there were significant differences between perceptions of family members of ADSCU residents and those of non-ADSCU residents regarding care their loved-ones are receiving on these qualities of care, controlling for frequency of visit. digital.library.unt.edu/ark:/67531/metadc84203/
Ancient Musical Ideas Through a Twenty-First Century Lens: An Examination of Tarik O’Regan’s Scattered Rhymes and Its Relationship to Guillaume de Machaut’s Messe de Notre Dame
British composer Tarik Hamilton O’Regan (b. 1978, London) is earning a reputation as an important composer of today. The innovative works of O’Regan are entering the spectrum of professional, educational, and community performing organizations across the United States and Europe. Scattered Rhymes’ intricate melodic, harmonic, and rhythmic relationships with Messe de Notre Dame by Guillaume de Machaut (c.1300-1377) make an examination and comparison of the two works significant. Analyzing Scattered Rhymes by tracing its roots to Guillaume de Machaut’s Messe de Notre Dame, results in a renewed interest in this ancient work and brings prominence to Tarik O’Regan’s modern musical interpretation of ancient ideas. Understanding Scattered Rhymes as a work based on ideas from the fourteenth century in fusion with compositional concepts rooted in the modern era promotes Scattered Rhymes as one that is valuable in the current musical landscape. digital.library.unt.edu/ark:/67531/metadc84235/
Can Positive Reinforcement Overcome Fear? An Investigation of Competing Contingencies
Escape maintained behavior in dogs is generally displayed by one of two behaviors-fleeing or aggression. Once aggression is negatively reinforced by the removal of the aversive stimulus, it is very difficult to eliminate from the organism's repertoire. Counterconditioning is the process of pairing a positive reinforcer with an aversive stimulus in the attempts that an organism will no longer exhibit fear responses in its presence. This process must be done gradually with small approximations. Many organisms have been trained to tolerate the presence of aversive stimuli via counterconditioning. However, this process can be time consuming and has inconsistent results. The purpose of this experiment was to monitor the effects of counter conditioning around an aversive stimulus while simultaneously training an identical behavior in the presence of a neutral stimulus. The results demonstrated that even though counterconditioning produced approach to the aversive stimulus the subject still exhibited numerous fear responses when results were compared to the control condition. digital.library.unt.edu/ark:/67531/metadc84232/
The Texas Confederate Home for Men, 1884-1970
Founded in 1886 by a local veteran’s organization, the Texas Confederate Home for Men served thousands of veterans throughout its tenure. State-run beginning in 1891, the facility became the center of controversy multiple times, with allegations of mistreatment of residents, misappropriation of funds, and unsanitary conditions in the home. Despite these problems, for several decades the home effectively provided large numbers of needy veterans with a place where they could live out their remaining years. The home was finally closed by the state in 1965, and the buildings were demolished in 1970. The facility’s success helped to inspire Texas to introduce a veteran pension system, and brought forth a new era in the state’s willingness to take care of veterans once their wars were over. digital.library.unt.edu/ark:/67531/metadc84231/
A Bidirectional Two-Hop Relay Network Using GNU Radio and USRP
A bidirectional two-hop relay network with decode-and-forward strategy is implemented using GNU Radio (software) and several USRPs (hardware) on Ubuntu (operating system). The relay communication system is comprised of three nodes; Base Station A, Base Station B, and Relay Station (the intermediate node). During the first time slot, Base Station A and Base Station B will each transmit data, e.g., a JPEG file, to Relay Station using DBPSK modulation and FDMA. For the final time slot, Relay Station will perform a bitwise XOR of the data, and transmit the XORed data to Base Station A and Base Station B, where the received data is decoded by performing another XOR operation with the original data. digital.library.unt.edu/ark:/67531/metadc84237/
Chirped-Pulse Fourier Transform Microwave Spectroscopy of Fluoroiodoacetonitrile and Chloropentafluoroacetone
This work focuses on finding the complete iodine and nitrogen nuclear electric quadrupole coupling tensors for fluoroiodoacetonitrile using chirped-pulse Fourier transform microwave spectroscopy. Fluoroiodoacetonitrile contains two hyperfine nuclei, iodine (I=5/2) and nitrogen (I=1) and the spectra were observed with great resolution. A total of 499 transitions were observed for this molecule. The a, b and c rotational constants were obtained. A study of chloropentafluoroacetone was also done using chirped-pulse Fourier transform microwave spectroscopy. The two chlorine isotopes for this molecule, Cl-35 and Cl-37 were observed and 326 and 170 transitions were recorded, respectively. digital.library.unt.edu/ark:/67531/metadc84230/
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 program resulted in an average increase of 16.1% in participants’ PA self-efficacy (effect size [ES] = 0.41), an increase from three of nine participants at pre-test to six of nine participants at post-test reporting to be in a stage of change in which they are most likely to be successful in regular PA participation (i.e., action or maintenance), and a comparable improvement in MPAI-4 scores (rehabilitation outcomes) after discharge to a rehabilitation program without a PA education component. In conclusion, the PACE program can improve PA self-efficacy, intention to change PA behaviors, and short-term rehabilitation outcomes. digital.library.unt.edu/ark:/67531/metadc84224/
Beyond Suzie Wong? An Analysis of Sandra Oh’s Portrayal in Grey’s Anatomy
In my study, I examine if and how Sandra Oh’s portrayal of Dr. Cristina Yang in Grey’s Anatomy, a primetime network drama, reifies or resists U.S. mediated stereotypes of Asian American females. I situate my intercultural study in an interpretive paradigm because I am want to explore how the evolving characteristics of existing the Asian American female mediated stereotype as they influence Asian American female identity. Additionally, I trace the historical development of Asian and Asian American stereotypes yellow peril to the model minority; and from Dragon Lady, Lotus Blossom, Geisha, and Suzie Wong. From my textual analysis, I suggest that when portrayals simultaneously reify and resist characteristics of existing Asian American stereotypes, they may help to breakdown perceived binaries of existing Asian and Asian American stereotypes. digital.library.unt.edu/ark:/67531/metadc84229/
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. digital.library.unt.edu/ark:/67531/metadc84226/
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. digital.library.unt.edu/ark:/67531/metadc84223/
Wilderness and Everyday Life.
I challenge the dualistic view of wilderness that has influenced wilderness philosophy, politics and experience in recent years. In its place, I offer an alternative vision that recognizes wilderness areas and working landscapes as complementary elements of a larger, inhabited landscape characterized by a heterogeneous mixture of human-land relational patterns representing various points along an urban-wilderness continuum. In chapters 2 through 4, I explore the philosophical, political and experiential implications of this wilderness-in-context vision. Experienced and understood as part of the landscape we call home, wilderness may engender, renew, and sustain an engaged and integrated wilderness practice involving regular contact with wilderness places, committed activism on behalf of wild lands and their inhabitants, and grounded reflection on the meaning and value of wilderness in our everyday lives. digital.library.unt.edu/ark:/67531/metadc84205/
Strong Choquet Topologies on the Closed Linear Subspaces of Banach Spaces
In the study of Banach spaces, the development of some key properties require studying topologies on the collection of closed convex subsets of the space. The subcollection of closed linear subspaces is studied under the relative slice topology, as well as a class of topologies similar thereto. It is shown that the collection of closed linear subspaces under the slice topology is homeomorphic to the collection of their respective intersections with the closed unit ball, under the natural mapping. It is further shown that this collection under any topology in the aforementioned class of similar topologies is a strong Choquet space. Finally, a collection of category results are developed since strong Choquet spaces are also Baire spaces. digital.library.unt.edu/ark:/67531/metadc84202/
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 campus climates vary and likely influenced the survey responses. digital.library.unt.edu/ark:/67531/metadc84225/
“Civilizations without Boats”: Stories
This collection consists of a critical preface and nine short stories. Extrapolating from the work and legacy of Michel Foucault, the preface theorizes a genre of “heterotopian fiction” as constitutive of a fundamentally ethical approach to narrative creativity, distinguishing its functional and methodological characteristics from works that privilege aesthetic, thematic, or technical artistry. The stories explore spaces of madness, alterity, incomprehensibility, and liminal experience. Collection includes the stories “Mexico,” “Civilizations without Boats,” The Widow’s Mother,” “Guys Like Us,” “Everything You’d Hoped It Would Be,” “A Concerned Friend,” “Crisis Hotline,” “Coast to Coast,” and “The Ghosts of Rich Men.” digital.library.unt.edu/ark:/67531/metadc84222/
Novice Generalist and Content teachers’ Perceptions of Contextual Factors Affecting Personal Teaching Efficacy
New teachers begin the school year with optimism and enthusiasm, but their excitement quickly wanes as they encounter the realities of the everyday life of a teacher. When they do not experience the successes they predicted, many begin to doubt their capabilities, which results in a lowered sense of teaching efficacy. This descriptive study was designed to identify the contextual factors novice teachers perceive as influences on personal teaching efficacy and to examine the relationships between the factors. Two groups of novice teachers who were concurrently enrolled in a post-baccalaureate accelerated educator preparation program and working as first-year teachers were the participants in the study. Data were gathered for the study through focus group activities, twice weekly journal entries completed during the teaching year, and a culminating “lessons learned” paper written during the last month of the first year of teaching. Each of the two focus groups identified nine contextual factors they perceived to affect personal teaching efficacy. Six factors were identified by both groups: parental involvement, support from administrators and colleagues, classroom discipline, testing results, teaching strategies and outcomes, and relationships with administrators and colleagues. The groups, however, perceived the relationships between the contextual factors differently. The generalists perceived recursive relationships between the factors, while the content group perceived a linear relationship. digital.library.unt.edu/ark:/67531/metadc84221/
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 theta-alpha crossover activity characterized by 3 minutes or more in duration, one microvolt or more in amplitude, and 3.75μv amplitude or more of beta. This defined therapeutic crossover condition does appear to facilitate recall of imagery and memories during alpha-theta neurofeedback and was related to better treatment outcomes. digital.library.unt.edu/ark:/67531/metadc84227/
Discretion, Delegation, and Professionalism: A Study of Outcome Measures in Upward Bound Programs
In our society, American citizens expect public policies to result in programs that address social problems in ways that are both efficient and effective. In order to judge if these two values are being achieved, public programs are often scrutinized through program monitoring and evaluation. Evaluation of public programs often is a responsibility delegated to local-level managers. The resulting discretion has to be balanced with the need for accountability that is also inherent in public programs. Evaluation is often difficult because outcomes are not readily measurable due to the complexity of the problems faced in the public setting. The Upward Bound program provides an example of this. Upward Bound provides services to students from low-income families and those in which neither parent holds a bachelor’s degree in order to increase the rate at which participants complete secondary education and enroll in and graduate from postsecondary institutions. Upward Bound is implemented and evaluated based upon specifications decided upon at the local level. This discretion granted to local level managers has resulted in wide variations in the way the program is being evaluated. This presents a problem for evaluation and has resulted in inconclusive results as to the success of the program. One way to correct this problem is to try and gain a clear understanding of how the evaluation outcome measures are being chosen for Upward Bound. My study accomplished this task. digital.library.unt.edu/ark:/67531/metadc84220/
Parent Involvement and Science Achievement: A Latent Growth Curve Analysis
This study examined science achievement growth across elementary and middle school and parent school involvement using the Early Childhood Longitudinal Study – Kindergarten Class of 1998 – 1999 (ECLS-K). The ECLS-K is a nationally representative kindergarten cohort of students from public and private schools who attended full-day or half-day kindergarten class in 1998 – 1999. The present study’s sample (N = 8,070) was based on students that had a sampling weight available from the public-use data file. Students were assessed in science achievement at third, fifth, and eighth grades and parents of the students were surveyed at the same time points. Analyses using latent growth curve modeling with time invariant and varying covariates in an SEM framework revealed a positive relationship between science achievement and parent involvement at eighth grade. Furthermore, there were gender and racial/ethnic differences in parents’ school involvement as a predictor of science achievement. Findings indicated that students with lower initial science achievement scores had a faster rate of growth across time. The achievement gap between low and high achievers in earth, space and life sciences lessened from elementary to middle school. Parents’ involvement with school usually tapers off after elementary school, but due to parent school involvement being a significant predictor of eighth grade science achievement, later school involvement may need to be supported and better implemented in secondary schooling. digital.library.unt.edu/ark:/67531/metadc84228/
The Effects of a Self-Monitoring Procedure on Sustainable Behavior
Self-monitoring procedures are commonly used to assess environmentally sustainable behavior. The current experiment evaluated the effects of a self-monitoring procedure on two sustainable behaviors within a university office. A senior assistant was asked to report on light usage and energy-saver use on the copier in an office break room. Her reports were then compared with independent observations. Results showed that her reports were highly correspondent with independent observations although no change in target behaviors occurred. Changes in behavior occurred when she was asked to engage in the target behaviors. Results suggest that although self-monitoring procedures can correctly assess sustainable behaviors, they may not be suitable for behavior change. digital.library.unt.edu/ark:/67531/metadc84201/
Responding to Child Sexual Abuse: Exploring the Case Files of Children Under the Age of 6 Admitted to a Children’s Advocacy Center for Evaluation
Research suggests that roughly 25% of women and 10% of men within the United States were sexually abused at some point during childhood. With such high rates of victimization affecting society, the current study explores a population of children under the age of 6 who were suspected of being sexually victimized and thus admitted to a children’s advocacy center (CAC) for evaluation. This investigation contributes to the literature concerning child sexual abuse (CSA) by exploring the characteristics of these alleged victims, the characteristics of their suspected offenders, the alleged victim’s familial demographics characteristics, and by looking at the data pertaining to the incarceration rates of the suspected offenders identified within the sample. digital.library.unt.edu/ark:/67531/metadc84207/
Analysis of Micro Enterprise Clusters in Developing Countries: A Case Study of Toluca, Mexico.
Businesses cluster to achieve agglomeration benefits. However, research in developing countries suggests that the economic environment limits small business’ propensity to benefit from agglomerations. The study examines the location, networking patterns, formal structures and owner characteristics of 1256 micro businesses from ten industries and thirteen sample areas in Toluca, Mexico. First, the thesis analyses whether clustering has a positive impact on the success rates of the surveyed enterprises, e.g. higher sales per employee. On an industry scale only Retail benefits from agglomerations economies. However, results of the neighborhood data show that specific areas benefit from urbanization economies. Overall, the study finds that businesses located within agglomerations, have higher levels of formalization, networking and professional training, hence constituting a more sophisticated base for economic development. Conclusions can be drawn for development policies and programs, arguing for a more differentiated approach of small business development depending on business location and cluster characteristics. digital.library.unt.edu/ark:/67531/metadc84200/
Combat Near-Death Experiences: An Exploratory, Mixed-Methods Study
This mixed-methods study’s purpose was a systematic comparison of contents and aftereffects of near-death experiences (NDEs) occurring in a variety of circumstances with those occurring in combat. They completed an online survey: a demographic questionnaire, the Near-Death Experience Scale, the Life Changes Inventory-Revised (LCI-R), and four narrative response items. Survey completers were 68 participants: 20 combat near-death experiencers (cNDErs) and 48 non-NDErs (nNDErs). The 29% of participants who met NDE Scale criterion for an NDE was comparable to NDE incidence findings from previous retrospective studies. For statistical analyses, significance was set at p < .05, and effect size (Cohen’s d) was calculated. Mean total NDE Scale scores were significantly lower for cNDErs than variety-of-circumstance NDErs from one of two comparable studies (t = 5.083, p < .0001, d = -1.26), possibly suggesting cNDEs may have “less depth” than other-variety NDEs. Regarding cNDE aftereffects, absence of previous LCI-R data made comparison impossible. Cronbach’s alpha analysis yielded acceptable reliability on the total scale and seven of nine subscales, a finding that matched Schneeberger’s (2010); however, factor analytic results did not support the hypothesized subscale structure of the LCI-R. Although cNDErs did not score significantly higher than nNDErs on the total scale or subscales after Bonferroni correction, results indicated a possible trend toward greater absolute changes (p = 0.02, d = 0.74) and spirituality (p = 0.02, d = 0.67) with the latter finding substantiated by narrative responses. Informal analysis of narrative responses yielded several themes. digital.library.unt.edu/ark:/67531/metadc84208/
The Parent-Initiated Task Motivational Climate and Factors Influencing Eighth Grade Boys’ Intention to Continue Sports
The motivational climate, as defined by parents’ behaviors, and athletes’ goal orientations are essential in understanding children’s experiences with sport. The purpose of this study was to examine the perceived motivational climate created by parents, and its relationship to psychological outcomes experienced by adolescent male athletes in youth sports. In particular, the parent created task climate was examined through its influence on goal orientation and subsequently to psychological outcomes experienced in sport, specifically, sport competence, self-esteem, enjoyment, and intention to continue participating in sport. Participants were 405 8th grade male athletes (mean age = 13.5); (Sample A: n = 205; Sample B: n = 200). As expected, the task-oriented parent initiated motivational climate was associated with the boys’ mastery goal orientation. Participants with higher mastery goal orientation had greater sport competence, self-esteem, and more enjoyment in sport. Intention to continue playing sport was predicted primarily by their level of enjoyment, and secondarily by their increased feelings of self-esteem. digital.library.unt.edu/ark:/67531/metadc84204/
Electrical and Structure Properties of High-κ Barium Tantalite and Aluminum Oxide Interface with Zinc Oxide for Applications in Transparent Thin Film Transistors
ZnO has generated interest for flexible electronics/optoelectronic applications including transparent thin film transistors (TFTs). For this application, low temperature processes that simultaneously yield good electrical conductivity and optical transparency and that are compatible with flexible substrates such as plastic, are of paramount significance. Further, gate oxides are a critical component of TFTs, and must exhibit low leakage currents and self-healing breakdown in order to ensure optimal TFTs switching performance and reliability. Thus, the objective of this work was twofold: (1) develop an understanding of the processing-structure-property relationships of ZnO and high-κ BaTa2O6 and Al2O3 (2) understand the electronic defect structure of BaTa2O6 /ZnO and Al2O3/ZnO interfaces and develop insight to how such interfaces may impact the switching characteristics (speed and switching power) of TFTs featuring these materials. Of the ZnO films grown by atomic layer deposition (ALD), pulsed laser deposition (PLD) and magnetron sputtering at 100-200 °C, the latter method exhibited the best combination of n-type electrical conductivity and optical transparency. These determinations were made using a combination of photoluminescence, photoluminescence excitation, absorption edge and Hall measurements. Metal-insulator-semiconductor devices were then fabricated with sputtered ZnO and high-κ BaTa2O6 and Al2O3 and the interfaces of high-κ BaTa2O6 and Al2O3 with ZnO were analyzed using frequency dependent C-V and G-V measurements. The insulator films were deposited at room temperature by magnetron sputtering using optimized processing conditions. Although the Al2O3 films exhibited a lower breakdown strength and catastrophic breakdown behavior compared to BaTa2O6/ZnO interface, the Al2O3/ZnO interface was characterized by more than an order of magnitude smaller density of interface traps and interface trapped charge. The BaTa2O6 films in addition were characterized by a significantly higher concentration of fixed oxide charge. The transition from accumulation to inversion in the Al2O3 MIS structure was considerably sharper, and occurred at less than one tenth of the voltage required for the same transition in the BaTa2O6 case. The frequency dispersion effects were also noticeably more severe in the BaTa2O6 structures. XPS results suggest that acceptor-like structural defects associated with oxygen vacancies in the non-stoichiometric BaTa2O6 films are responsible for the extensive electrical trapping and poor high frequency response. The Al2O3 films were essentially stoichiometric. The results indicate that amorphous Al2O3 is better suited than BaTa2O6 as a gate oxide for transparent thin film transistor applications where low temperature processing is a prerequisite, assuming of course that the operation voltage of such devices is lower than the breakdown voltage. Also, the operation power for the devices with amorphous Al2O3 is lower than the case for devices with BaTa2O6 due to the smaller fixed oxide charges and interface trap density. digital.library.unt.edu/ark:/67531/metadc84233/
Nanoscale Materials Applications: Thermoelectrical, Biological, and Optical Applications with Nanomanipulation Technology
In a sub-wavelength scale, even approaching to the atomic scale, nanoscale physics shows various novel phenomena. Since it has been named, nanoscience and nanotechnology has been employed to explore and exploit this small scale world. For example, with various functionalized features, nanowire (NW) has been making its leading position in the researches of physics, chemistry, biology, and engineering as a miniaturized building block. Its individual characteristic shows superior and unique features compared with its bulk counterpart. As one part of these research efforts and progresses, and with a part of the fulfillment of degree study, novel methodologies and device structures in nanoscale were devised and developed to show the abilities of high performing thermoelectrical, biological, and optical applications. A single β-SiC NW was characterized for its thermoelectric properties (thermal conductivity, Seebeck coefficient, and figure of merit) to compare with its bulk counterpart. The combined structure of Ag NW and ND was made to exhibit its ability of clear imaging of a fluorescent cell. And a plasmonic nanosture of silver (Ag) nanodot array and a β-SiC NW was fabricated to show a high efficient light harvesting device that allows us to make a better efficient solar cell. Novel nanomanipulation techniques were developed and employed in order to fabricate all of these measurement platforms. Additionally, one of these methodological approaches was used to successfully isolate a few layer graphene. digital.library.unt.edu/ark:/67531/metadc84238/
An Investigation of the Relationship between HIV and Prison Facilities in Texas: The Geographic Variation and Vulnerable Neighborhood Characteristics
Previous research suggests that prisons may be fueling the spread of HIV infection in the general population. In 2005, the HIV rate was more than 2.5 times higher in US prison populations. Environmental factors in prisons such as illicit drug use and unprotected sexual activities can be conducive for HIV transmission. Because the vast majority of prison inmates are incarcerated for less than three years, transmission of HIV between prison inmates and members of the general population may occur at a high rate. The environment in which an individual lives and the entities that comprise it affect the health of that person. Thus the location of prisons within communities, as well as socio-demographic characteristics may influence the geography of HIV infection. HIV surveillance data, obtained from the Texas Department of State Health Services, were used to investigate the relationship between the location of prison units in Texas and HIV infection rates in the surrounding zip codes. The results suggest that HIV prevalence rates are higher among geographic areas in close proximity to a prison unit. With continued behavioral risks and low treatment adherence rates among individuals infected with HIV, there is a possibility of increased HIV prevalence. Vulnerable places, locations with higher HIV prevalence, should be targeted for resource allocation and HIV prevention and care service. This study illustrates the importance of spatial analysis of places vulnerable to increased HIV prevalence in creating more effective public health prevention strategies and interventions. digital.library.unt.edu/ark:/67531/metadc84234/
