This study explored NCAA athletic departments' mental health screening practices, including the mental health concerns assessed for by the mental health screening, personnel responsible for administering and reviewing screeners, and resources available for athletes identified as "at risk." Participants were athletic department staff who had knowledge of their school's mental health screening processes. Frequencies and chi-square analyses were used to assess trends across divisional levels (DI vs. DII/DIII). Analyses show that significantly more DI than DII/DDIII institutions have a formal mental health screening program. Institutions' coverage of mental health topics in their screening did not vary significantly by Divisional level, with one exception: a larger percentage of DI institutions assessed whether student athletes had worked with a mental health practitioner than DII/DIII schools. DII/III were significantly more likely to have athletic trainers both administer and review mental health screeners and DI institutions were significantly more likely to have a sport psychologist employed within their athletic department than. DI schools were significantly more likely to have had a student athlete attempt suicide and participate in inpatient treatment than DII/III schools. Implications of the findings, limitations, and future directions are discussed.

This research seeks to explore how the metal arts are taught to women in Kuwait in an undergraduate setting, making the call for the use of feminist pedagogy when teaching the metal arts to women in Kuwait. This research is achieved using the qualitative methodology of analytic autoethnography. The theoretical framework is a feminist lens bridging the social construction of gender with the gendering of objects and feminist standpoint theory. The data comes from the experiences of creating three of my own pieces of artwork as well as the pieces themselves in tandem with historical, political, and cultural contexts. The analysis from this research is then bridged with feminist pedagogy in order to begin to develop an inclusive metal arts curriculum for women in Kuwait.

Federal and state descriptions of gifted and talented services include identifying and developing leadership talent, but in many states, services are not mandated or funded. Consequently, leadership development is often left to extracurricular programs (e.g., student organizations, athletics). The Junior Reserve Officers' Training Corps (JROTC) provides school-based military-focused leadership education and opportunities to apply emergent leadership skills. This qualitative descriptive study examined leadership talent development in JROTC and the postsecondary paths participants chose. A self-report survey was distributed to graduating seniors enrolled in JROTC in Texas public high schools and semi-structured interviews were conducted with JROTC instructors across the state. The findings highlighted characteristics of students in the sample who chose to pursue military-focused education or careers after high school and themes about the experiences and key considerations related to choosing postsecondary paths. JROTC instructors supported students with differentiated development plans and information about flexible pathways to reach postsecondary goals. Students benefitted from broad definitions of success, exposure to career options, realistic self-assessment, and alignment between intentions and preparation.

Despite advancements in research on sexual morphology as well as increasing interdisciplinary theory on gender, medicine continues to perpetuate anti-transgender stigma in health care. Research on this topic has typically lacked perspectives from health professionals, who operate in and contribute to the environments in which patients seek care. In collaboration with Dallas non-profit Trans Pride Initiative, this study seeks to begin filling this research gap, relying on a sexual stigma framework created by Gregory Herek and applying it to anti-transgender (or gender) stigma to examine its manifestations in health care environments through narrative inquiry. The data from narrative interviews with health care professionals revealed themes of inadequate schooling on transgender competency models and health needs, difficulties in resisting gatekeeper practices while addressing mental health needs, a patient-as-expert approach amongst trans-affirming providers, and understanding of patient family dynamics as a catalyst for understanding stigma. Exploration of sexual identity prior to claiming gender identity, lacking language to explain gender experiences until encountering other LGBTQ+ (lesbian, gay, bisexual, transgender, queer) people, and religious trauma as restrictive to gender exploration during childhood emerged as themes amongst transgender and gender diverse participant interviews. The practical implications of these themes present issues for institutional, social, and …

Magnetic nano-clusters in silicon involving iron and cobalt were synthesized using low energy (50 keV) ion implantation technique and post-implantation thermal annealing. Before the irradiation, multiple ion-solid interaction simulations were carried out to estimate optimal ion energy and fluence for each experiment. For high-fluence low-energy irradiation of heavy ions in a relatively lighter substrate, modeling the ion irradiation process using dynamic code SDTrimSP showed better agreement with the experimental results compared to the widely used static simulation code TRIM. A saturation in concentration (~ 48%) profile of the 50 keV Fe or Co implants in Si was seen at a fluence of ~ 2 × 1017 ions/cm2. Further study showed that for structures with a curved surface, particularly for nanowires, better simulation results could be extracted using a code "Iradina" as the curve geometry of the target surface can be directly defined in the input file. The compositional, structural, and magnetic properties were studied using Rutherford backscattering spectrometry, X-ray photoelectron spectroscopy, X-ray diffraction, atom probe tomography, and vibrating sample magnetometry. Irradiation of high-current (~ 2 μA/cm2) 50 keV Fe ions into Si at a fluence of 2 × 1017 ions/cm2 showed the formation of Fe5Si3 nano structures in the near-surface …

The purpose of this descriptive case study was to explore the self-perception of three rural, intermediate, ELA teachers to motivate their students to read for pleasure. The methods utilized in this study included one-on-one interviews, and a focus group discussion, including all three participants and the researcher. The subjects shared teaching strategies from their childhoods that succeeded and failed in motivating them to read. The biographical perspective proposed by Kelchtermans and Vandenberghe allows us to see how the teachers' biographies influenced their instructional beliefs. Through this lens, it was revealed that, in their current classrooms, the teachers in this study utilize strategies they recalled from childhood as motivational. For example, they have confidence in read-alouds, literary freedom of choice, the development of positive student-teacher relationships, and engaging lessons that are significant to the students. Further, they avoid strategies they recollect from childhood that failed to motivate them to read such as teacher-chosen literature and lessons they believed were irrelevant. Findings have the potential to inform teachers, teacher educators, school administrators, and in-service providers of the nature of beliefs and intentions regarding reading motivation that rural, ELA teachers possess.

The early signaling mechanism(s) that control oxidant perception and signal transduction leading to activation of the antioxidant defense response and survival mechanisms tailored toward specific oxidative insult remains unknown. Here, we identified early changes in metabolome and proteome of S. cerevisiae in response to hydrogen peroxide, menadione, cumene hydroperoxide, and diamide. Firstly, global untargeted LC–MS/MS analysis allowed us to identify 196 proteins in response to hydrogen peroxide, 569 proteins in response to cumene hydroperoxide, 369 proteins in response to menadione and 207 proteins in response to diamide that were significantly regulated at 3 min after exposure. We revealed that each oxidant triggered unique signaling mechanisms associated with survival and repair mechanisms as early as 3 minutes of post treatment with a set of proteins that uniquely responded to the particular oxidant. In addition, our comprehensive pathway analysis revealed signaling pathways and the molecular players that are regulated globally by all oxidants at early time points namely Ran, mTOR, Rho, and eIF2. Additionally, we analyzed metabolic response using targeted GC-MS/MS that allowed us to identity 35 metabolites that were consistently detected in all samples at 3 min of exposure. These metabolites showed distinct response to the four oxidants in carbohydrate metabolism, …

Past research has provided evidence for cultural differences in episodic memory when comparing European American and East Asian samples. However, cultural cognitive neuroscience has become over-dependent on European American vs. East Asian samples, which has left very little research into groups outside of this dichotomy. The aim of this dissertation was to address the need of more diverse samples in cultural cognitive neuroscience and to address the lack of research on Latinx biculturals. In this dissertation I explored how language could serve as a priming method to activate specific cultural systems, how bicultural Latinxs may switch cultural frames through language priming, and how priming of cultural systems affects their perception and recognition memory for certain visual information. The present study was designed to include a specific technique to investigate the potential cross-modal effect of cultural priming through language on visual cognition in bicultural and bilingual Latinxs. Results suggest that language did prime bicultural Latinxs to perform differently in a behavioral task, where images encoded in Spanish were more likely to be identified as incorrect and images encoded in English were more likely to be identified as correct. Additionally, we found that Cultural Blendedness directly predicted recognition accuracy, where higher identification …

The purpose of this phenomenological study is to explore the experiences of Black graduates of historically Black colleges and universities who attend graduate school at predominately White institutions as they adjust academically and socially at these institutions. In-depth interviews provide knowledge as to what this special population of students' experience. Recommendations for faculty and administrators to assist with the recruitment and retention of these graduate students is also provided.

This dissertation investigates the My Stealthy Freedom (MSF) movement, an online movement against mandatory hijab laws in Iran, building on two leading lead social movements' theories, political processes and framing processes theories. Study 1 explores the utility of a tactical approach for explaining the movement's pace of insurgency. I employ a conceptual repertoire focused upon the political process model's core concepts of tactical innovation and tactical adaptations, supplementing these older concepts with the more recently proposed concept of tactical freeze and a newly proposed concept of tactical hashtags that is of particular relevance to online movements. Study 2 focuses on extracting hidden patterns and emotional characteristics in the MSF movement by conducting a topic modeling study on the text appearing in the captions of the main account of the movement on Instagram. It was shown that the actions of Masih Alinejad, the founder of the movement, represented by her online activity and extracted by means of topic modeling, is directly affected by the sequence of important events happening in Iran concluding to a transformation of a social movement to political one. Study 3 models how social movements use social media in the formation of affective publics and apply this model …

Waste-heat-to-power (WHP) recovers electrical power from exhaust heat emitted by industrial and commercial facilities. Waste heat is available in enormous quantities. The U.S. Department of Energy estimates 5-13 quadrillion BTUs/yr with a technical potential of 14.6 GW are available and could be utilized to generate power by converting the heat into electricity. The research proposed here will define a system that can economically recover energy from waste heat through a thermal regenerative electrochemical system. The primary motivation came from a patent and the research sponsored by the National Renewable Energy Laboratory (NREL). The proposed system improves on this patent in four major ways: by using air/oxygen, rather than hydrogen; by eliminating the cross diffusion of counter ions and using a dual membrane cell design; and by using high concentrations of electrolytes that have boiling points below water. Therefore, this system also works at difficult-to-recover low temperatures. Electrochemical power is estimated at 0.2W/cm2, and for a 4.2 M solution at 1 L/s, the power of a 100 kW system is 425 kW. Distillation energy costs are simulated and found to be 504 kJ/s for a 1 kg/s feed stream. The conversion efficiency is then calculated at 84%. The Carnot efficiency for …

In recent years, deep learning based computer vision technology has developed rapidly. This is not only due to the improvement of computing power, but also due to the emergence of high-quality datasets. The combination of object detectors and drones has great potential in the field of rescue and disaster relief. We created an image dataset specifically for vision applications on drone platforms. The dataset contains 5000 images, and each image is carefully labeled according to the PASCAL VOC standard. This specific dataset will be very important for developing deep learning algorithms for drone applications. In object detection models, loss function plays a vital role. Considering the uneven distribution of large and small objects in the dataset, we propose adjustment coefficients based on the frequencies of objects of different sizes to adjust the loss function, and finally improve the accuracy of the model.

Oklahoma History is a collection of poetry that examines the speaker's relationship to and critique of her home state, Oklahoma. The poems navigate race and gender as they intersect with local histories, culture, and religion, which complicates and often contradicts what the speaker is taught through childhood, adolescence, and into adulthood. The creative portion is accompanied by a critical preface which looks at how the poems and other writings of Oklahoma poet Joy Harjo impact the author's writing.

The method of optical emission spectroscopy has been used with Fe-Ni and other complex alloys to investigate in-situ compositional control for additive manufacturing. Although additive manufacturing of metallic alloys is an emerging technology, compositional control will be a challenge that needs to be addressed for a multitude of industries going forward for next-gen applications. This current scope of work includes analysis of ionized species generated from laser and metal powder interaction that is inherent to the laser engineered net shaping (LENS) process of additive manufacturing. By quantifying the amount of a given element's presence in the electromagnetic (EM) spectrum, this amount can be compared to the actual amount present in the sample via post-processing and elemental dispersive x-ray (EDX) data analysis. For this work a commercially available linear silicon CCD camera captured metallic ion peaks found within the ultraviolet (UV) region to avoid background contamination from blackbody radiation. Although the additive manufacturing environment can prove difficult to measure in-situ due to time dependent phenomena, extreme temperatures, and defect generation, OEM was able to capture multiple data points over a time series that showed a positive correlation between an element's peak intensity and the amount of that element found in the …

High entropy alloys (HEAs), also referred to as complex concentrated alloys (CCAs), are a relatively new class of alloys that have gained significant attention since 2010 due to their unique balance of properties that include high strength, ductility and excellent corrosion resistance. HEAs are usually based on five or more elements alloyed in near equimolar concentrations, and exhibit simple microstructures by the formation of solid solution phases instead of complex compounds. HEAs have great potential in the design of new materials; for instance, for lightweight structural applications and elevated temperature applications. The relation between grain size and yield strength has been a topic of significant interest not only to researchers but also for industrial applications. Though some research papers have been published in this area, consensus among them is lacking, as the studies yielded different results. Al atom being a large atom causes significant lattice distortion. This work attempts to study the Hall-Petch relationship for Al0.3CoFeNi and Al0.3CoCrFeNi and to compare the data of friction stress σ0 and Hall-Petch coefficient K with published data. The base alloys for both these alloys are CoFeNi and CoCrFeNi respectively. It was observed by atom probe tomography (APT) that clustering of Al-Ni atoms in …

Children experience a multitude of benefits in response to interactions with nature. Despite documented effects, children have increasingly spent less time outdoors over the last century and experienced higher rates of physical and emotional illnesses. Although child-centered play therapy (CCPT) is a culturally and developmentally responsive mental health treatment for children, researchers have limited study of environmental structure and materials employed in the therapeutic process of CCPT. In this study, I sought to further research on the integration of nature with CCPT by providing CCPT in an outdoor, contained playroom equipped with traditional CCPT toys and additional nature materials. Participants were 13 children in the southwestern U.S. with parent-reported attentional or self-regulation concerns (9 males, 6 females; ages 5-10, mean age M = 8.0). Parents reported participants' racial identities were 13% Black (n = 2), 13% Latinx (n = 2), 7% Turkish (n = 1), and 67% White (n = 10). Participants received 8 weeks of twice-weekly CCPT in an outdoor playroom. Results of two repeated measures ANOVAs revealed statistically significant improvement in attention on the Brown EF/A Scales and statistically significant improvement in social-emotional competencies on the SEARS-P. Results of this study illustrate the possible benefits of theoretically integrating …

Parkinson's disease (PD) is a neurodegenerative disease that affects motor abilities with increasing severity as the disease progresses. Traditional methods for diagnosing PD require specialists scoring qualitative symptoms using the motor subscale of the Unified Parkinson's Disease Rating Scale (UPDRS-III). Using force-plate data during quiet standing (QS), this study uses machine learning to target the characterization and prediction of PD and UPDRS-III. The purpose of predicting different subscores of the UPDRS-III is to give specialists more tools to help make an informed diagnosis and prognosis. The classification models employed classified PD with a sensitivity of 87.5% and specificity of 83.1%. Stepwise forward regression indicated that features correlated with base of support were most useful in the prediction of head rigidity (r-square = .753). Although there is limited data, this thesis can be used as an exploratory study that evaluates the predictability of UPDRS-III subscores using QS data. Similar prediction models can be implemented to a home setting using low-cost force plates as a novel telemedicine technique to track disease progression.

Teachers face pressures to meet the needs of an ever-changing diverse population of learners while simultaneously attempting to assist students in meeting state standards. There is a body of research that supports emergent bilinguals' growth in reading and writing. However, those practices do not necessarily reflect classroom instruction nor the needs of the students. The purpose of this study was to examine adolescent emergent bilinguals' perceptions about their learning from research-based literacy practices implemented in a classroom designed as a third space. Data were collected using participatory research and photo-elicitation and were analyzed using inductive analysis. The emergent bilinguals provided their insights about class assignments. Findings revealed that research-based literacy practices support emergent bilinguals' perceptions of learning when they are made accessible to them in distinctive yet extensive ways. For students to uncover which literacy activities they value, teachers need to present them with various opportunities to explore their own learning and encourage them to take ownership of their learning. Educators must consider the unique and individual needs of emergent bilinguals when designing the classroom environment and the lessons based on the standards. Recommendations for practitioners, professional development coordinators, and researchers are presented.

Doing, undoing, and redoing gender debates have established the omnirelevance and performativity of gender. Yet, little is known about the ways that individuals "do" gender in spaces that provide the opportunity for norms to be disrupted, such as subcultures. This study offers an empirical investigation into the performance of gender within the subculture known as EDM (electronic dance music) culture. Using 20 in-depth interviews that were conducted virtually, I analyze the way ravers experience and give meaning to gender within the EDM culture. I find that individuals within the EDM culture can participate in the doing, undoing, and redoing of gender and do so through the embodiment of their subcultural beliefs and ideology, known as PLUR (peace, love, unity, and respect). I argue that the embodiment of PLUR is gendered, and describe the body-reflexive practices that are associated with PLUR.

Purity culture was a movement created by evangelical Christian organizations in the United States and backed by marketing campaigns, media, churches, and sex education beginning in the 1990s. This movement was founded on the idea that young men and women should remain abstinent before marriage, thereby remaining in a state of "purity" for their future spouse. In purity culture messaging, women were positioned as sexual gatekeepers while men were framed as having little or no control over their sexual impulses, causing most of the purity expectation to fall on women. While the concept of remaining "pure" is not new, purity culture taught a new generation of women to feel ashamed and fearful of their sexuality and existed alongside an increasingly sexualized media landscape. This study analyzes purity culture and anti-purity culture themes that exist within television shows as well as how women perceive purity culture messaging and the effects this messaging had on their lives.

Erika Cudworth's Developing Ecofeminist Theory provides a helpful foundation for a non-essentialist, properly intersectional ecofeminist account of oppression, marginalization, and domination, but her rejection of what she refers to as "postmodernism" appears to be based on a misreading of Judith Butler. I attempt to provide a synthesis of Cudworth's framework with Butler, particularly through the use of Karen Barad's agential realism, in order to provide possibility for new alliances between ecofeminism and other anti-oppressive frameworks. I then examine what it might look like to do ecofeminist praxis, given the complex view of agency, ontology, and intersectionality rendered by such a synthesis. I draw from bicycling as an example from which to extrapolate what it means to resist oppression, and then draw from the Philosophy for Children movement to consider what such resistance might look like within the classroom. This dissertation thus attempts to move from theory to practice, recognizing that "the real world" is both always at hand and also subject to performative deconstruction.

Leo Brouwer's Sonata Mitología de las Aguas No. I for flute and guitar, first published in 2017, has taken its place as an important twenty-first-century addition to the flute and guitar duo repertory. I provide a brief historical context for the work, followed by preparation guides for guitar alone and duo passages. My preparation guides include exercises and rehearsal strategies, focusing on those passages of the work that include controlled indeterminacy. The study of indeterminacy in music is unusual in the pedagogy of the classical guitarist; this leaves guitarists unprepared for dealing with pieces, especially chamber works, that use improvisation or aleatoric music as a primary element. I take a multifaceted approach to facilitate the realization of the indeterminate sections of the work; this includes demonstrations of my traditional music notation transcriptions and other rehearsal strategies and the application of music performance study systems by James Thurmond and Marcel Tabuteau. This document aims to provide guidance to creating an organic, natural aesthetic in the actualization of Brouwer's groundbreaking work.

This research examines the political implications of community-police relations in the United States by exploring the link between race, perceptions of police performance, and trust in government. Relying on survey data, I examine these relationships for Blacks, Latinos, Asians, and Whites. In addition to examining the broader relationship between community-police relations and institutional trust, this dissertation examines (1) how police perceptions influence individuals' comfort in contacting the police, (2) how police violence and police perceptions influence trust in government, and (3) the effectiveness of community-oriented policing in building community-police relations and increasing trust in government. First, I find that these relationships are conditional on race and ethnicity. Black respondents, who are more likely to experience negative interactions with the police and who are less likely to have positive perceptions of the police, are less comfortable contacting them. Second, while police violence does not have a significant effect on public trust in government, police perceptions and perceptions of discrimination do. Respondents that perceive the police to be performing well and who do not believe their own racial group is being discriminated against, are more likely to express trust in government. Finally, I find that community-oriented policing has the potential to both …

In 1895, Emil Georg Conrad Sauer (1862-1942), a world-renowned German pianist and former student of Franz Liszt wrote his first piano concerto, which was published five years later in 1900. Sauer performed it extensively to enthusiastic crowds in Europe and the United States while on tour during the next several years. Then it vanished from the concert repertoire. It is no longer performed and has only been commercially recorded once. The purpose of this dissertation is to establish why it might have disappeared, and why there is value in bringing it back to the standard piano repertoire.
