This dissertation consists of three studies that collectively investigate the factors influencing the consumer adoption intention towards emerging healthcare technologies. Essay 1 systematically reviews the extent literature on healthcare technology adoption and serves as the theoretical foundation of the dissertation. It investigates different models that have been previously applied to study healthcare technology acceptance. Meta-analysis method is used to quantitatively synthesize the findings from prior empirical studies. Essay 2 posits, develops, and tests a comprehensive biotechnology acceptance model from the end-user's perspective. Two new constructs, namely, perceived risk and trust in technology, are integrated into the unified theory of acceptance and use of technology. Research hypotheses are tested using survey data and partial least square – structural equation modeling (PLS-SEM). Essay 3 extends the findings from the Essay 2 and further investigates the consumer's trust initiation and its effect on behavioral adoption intention. To achieve this purpose, Essay 3 posits and develops a trust model. Survey data allows testing the model using PLS-SEM. The models developed in this dissertation reflect significant modifications specific to the healthcare context. The findings provide value for academia, practitioners, and policymakers.

Value-added models (VAMs) have become widely used in evaluating teacher accountability. The use of these models for high-stakes decisions making has been very controversial due to lack of consistency in classifying teachers as high performing or low performing. There is an abundance of research on the impact of various student level covariates on teacher value-added scores; however, less is known about the impact of teacher-level and school-level covariates. This study uses hierarchical linear modeling to examine the impact of including teacher characteristics, school characteristics, and student demographics aggregated at the school level on elementary mathematics and reading teacher value-added scores. Data for this study was collected from a large school district in north Texas. This study found that across all VAMs fitted, 32% of mathematics teachers and 37% of reading teachers changed quintile ranking for their value-added score at least once across all VAMs, while 55% and 65% of schools changed their quintile ranking of value-added scores based on mathematics and reading achievement, respectively. The results show that failing to control for aggregated student demographics has a large impact on both teacher level and school level value-added scores. Policymakers and administrators using VAM estimates in high-stakes decision-making should include teacher- …

Children with disabilities are three to four times more likely to be abused than their non-disabled peers due to the impact of challenges related to behavior, cognition, language, social skills, and communication skills. In September of 2018, the Council for Exceptional Children (CEC) specifically noted the need to establish maltreatment prevention and response curricula and promote research and advocacy surrounding maltreatment of children with disabilities. One common curriculum recommended is Kidpower®. While Kidpower® shows promise in increasing people safety skills and offers some basic accommodations for use with disabled populations, a complete accommodation plan for deaf or hard of hearing students has not been developed. The purpose of this study was to explore how Kidpower® curriculum could be accommodated to meet the unique needs of deaf and hard of hearing students from the perspective of the deaf education community, including deaf adults, deaf education teachers, deaf education teacher preparation faculty, and parents with deaf or hard of hearing children. A combination of focus groups and interviews were utilized to review lessons and homework from the Kidpower® curriculum. Participants gave feedback on obstacles and ideas for accommodations and modifications that would mediate the challenges. Data were inductively coded and analyzed for …

Switchable adhesives using stimuli-responsive systems have many applications, including transfer printing, climbing robots, and gripping in pick and place processes. Among these adhesives, electroadhesive surface can spontaneously adjust their adhesion in response to an external electric field. However, electroadhesives usually need high voltage (e.g. kV) and the adhesion disappears upon turning off the signal. These limitations make them complicated and costly. In this research, we demonstrated a gold-coated silica microsphere (GCSM) with highly switchable and memorable adhesion triggered by a relatively small voltage (<30 V). In the experiment, a silica microsphere with a diameter of 15 μm was glued to a tipless atomic force microscope (AFM) cantilever. The nanoscale thick gold coating was sprayed on the surface of the microsphere by a sputter coater. AFM was used to explore the tunable adhesion with an external voltage at different relative humidity (RH). The results revealed that when applying a positive electrical bias at high RH, the adhesive force increased dramatically while it decreased to almost zero after applying a negative potential. Even if the bias was turned off, the adhesive force state could still be kept and erased on demand by simply applying a negative voltage. The adhesive force can be …

This thesis is focused on dynamic assessment (DA), an instructional approach based on Vygotskian sociocultural theory, applied to French pronunciation instruction, which can be neglected or inconsistent in the foreign language curriculum. DA aims to combine instruction and assessment into a cooperative, mediated approach in which the mediator works with the learner to identify and develop emergent abilities. These emergent abilities can appear in what is often referred to as the zone of proximal development (ZPD), or the difference between what a learner can do independently and what he/she can do with mediation, which in the present study was the difference between what the participant could pronounce correctly with or without mediation. In carrying out an individual DA session with a learner, the author aimed to find suggestions of potential benefits by applying DA to French pronunciation instruction and gain a more detailed understanding of the learner's performance than is generally possible from a traditional assessment, which is totally devoid of mediation for the sake of validity and reliability. The study includes a discussion of some potential benefits and limitations related to the use of DA for teaching French pronunciation to intermediate L2 learners based on what was observed in …

Wii Fit U games utilize a Wii Balance Board™ (WBB) in a manner that can provide precise feedback contingencies similarly to some forms of balance rehabilitation, thereby potentially increasing the dose of quality therapy with or without the presence of a therapist during post-brain injury rehabilitation. Additionally, an engaging video-game could improve treatment adherence, a critical aspect of making positive functional gains, by potentially increasing the rate and quality of reinforcement embedded in therapy. The present study had three aims: (1) develop a rigorous behavioral therapy for improving balance in individuals living with chronic brain injury using a Wii Fit U game and the WBB; (2) evaluate the program's effects on balance measures using a within-subject experimental design; and (3) assess social validity of behavioral gains by evaluating the program's effects on participant's "subjective balance confidence" (i.e., their Activities-Specific Balance Confidence (ABC) scores). A reversal design is proposed for use with primary study participants, wherein the experimental gameplay condition and no intervention condition are alternated for 6 to 10 weeks. A similar design was used in a truncated fashion with pilot participants, and a multiple baseline design was used with follow-up pilot participants. It was expected that participants would exhibit …

The purpose of this convergent mixed method study was to determine whether or not there is a difference in the perceived and actual financial literacy scores of millennials. Exploring the following research questions and hypotheses helped to expand knowledge around actual financial literacy and several other characteristics, including perceived financial literacy, especially among millennials (individuals born between 1981 and 1996): RQ1: What is the difference between millennials' actual and perceived financial literacy scores? RQ2: To what extent do socioeconomic status, gender, and having a bank account predict millennials' financial literacy scores? H0: There is no relationship between millennials' socioeconomic status, gender, banking status and their financial literacy scores. RQ3: What video delivery methods (if any) are millennials using to gain financial literacy knowledge in informal learning environments? Millennial participants (N = 207) were asked to complete a survey. Participants' perceived financial literacy scores were higher than their actual financial literacy scores. While males had higher perceived financial literacy ratings, females accounted for the majority of participants who scored four or above on a 5-point scale for actual financial literacy. Although, the null hypothesis was incorrect, the independent variables used in the ANOVA tables accounted for less than 15% of financial …

In 2018, global gross domestic product (GDP) was US$86.3 trillion, and almost a quarter of that value was due to international trade with a value of US$19.6 trillion. Air cargo accounts for about 35 percent of that trade value (approximately US$6.86 trillion). Moreover, from the perspective of the airport sector, air cargo revenue contributes between 20 to 70 percent of airport revenue. The global airport revenue for freight in 2018 was US$250 billion. Despite the interest and research activities surrounding competition and competitiveness of airports and specifically among airlines and passengers, it appears scholars have overlooked research concerning the competitiveness of airports when it comes to air cargo. This study attempts to fill the gap in the supply chain and logistics literature by putting forward a framework and ultimately operationalizing the framework highlighting the pivotal role of air cargo in the supply chain domain and within the global economy. Specifically, the framework is operationalized within the freight forwarding air cargo supply chain domain – providing insight into this important yet understudied phenomenon. The population of interest is freight forwarders from the Dubai International Airport, United Arab Emirates. The Middle East represents 18 percent of the world's air cargo volume and …

Climate change is a growing problem for those living in the Himalayas, threatening water availability and livelihoods. This research seeks to explore the various factors contributing to water shortage and the factors leading to perceptions of water shortage in Himachal Pradesh, India. This thesis explores data collected from 50 interviews conducted in summer 2019 and seeks to understand why participants of these interviews indicated that they do not experience water shortage. The research highlights the importance of further research and needed action in terms of addressing and mitigating the impacts of climate change in the Himalayas of Himachal Pradesh.

Violin repertoire composed in the late twentieth and early twenty-first centuries placed new demands on performers. While numerous pedagogues have written etudes and treatises analyzing traditional techniques, far fewer have thoroughly examined contemporary techniques. Many of the existing etudes and exercises inspired by contemporary violin repertoire are of a very high difficulty level and may seem unapproachable to students with little to no experience performing the music of recent decades. As a result, many violin students are unacquainted with the language of new music. This dissertation is intended to help fill a gap in the pedagogical literature by serving as a resource that familiarizes advanced students with the notation and proper execution of the non-traditional techniques commonly found in contemporary violin music. This document includes a survey of violin repertoire written since 1970, an analysis of the non-traditional techniques used most often in the works examined, methods for approaching specific technical problems that arise in them, and nine etudes originally composed by this author. The etudes focus on nine contemporary techniques, ranging from contact point variations to changing subdivisions, and are intended for study by advanced violinists interested in performing contemporary music.

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 research project sought to holistically understand how educators in Texas understand educational policies that impact LGBT students, their practices, and interventions in the classroom. The project looks at two policies: anti-bullying and sexual education policies, and provides evidence that they are intrinsically linked through the discourse surrounding LGBT issues in Texas schools.

François Couperin (1668-1733) was one of the earliest French Baroque composers to merge the Italian style into the French tradition. He had great influence on the development of French Baroque music from the end of the seventeenth century until his death. Couperin's four Concerts Royaux and the ten Concerts Nouveaux (published in 1722 and 1724) were written for the enjoyment of Louis XIV. Those suites were popular in the court before they were published, as they were requested to be performed every Sunday during the years 1714 and 1715 to give pleasure to the king. Rittrato dell'amore is the ninth suite out of the fourteen suites. The purpose of this study is to provide a performance guide and a practical edition of François Couperin's Neuvième Concert Ritratto dell' amore. It also contrasts Italian style and French tradition in the Baroque period, and how Couperin blended both styles together in his Neuvième Concert. In addition, this dissertation summarizes the general principles of Baroque performance practice that one may encounter in Neuviéme Concert, including notes inégales (unequal notes), ornamentation, over-dotting, and other issues. It is especially important for one to understand the performance style of French Baroque music in order to perform …

NASCION-type lithium-aluminum-germanium-phosphate (LAGP) glass-ceramic is one of the most promising solid electrolyte (SEs) material for the next generation Li-ion battery. Based on the crystallization of glass-ceramic material, the two-step heat treatment was designed to control the crystallization of Li-ion conducting crystal in the glass matrix. The results show that the LAGP crystal is preferred to internally crystalize, Tg + 60%∆T is the nucleation temperature that provides the highest ion conductivity. The compositional investigation also found that, pure LAGP crystal phase can be synthesized by lowering the amount of GeO2. To fill gap of atomic structure in LAGP glass-ceramic, molecular dynamic (MD) simulation was used to build the crystal, glass, and interfacial structure LAGP. The aliovalent ion substitution induced an simultaneously redistribution of Li to the 36f interstitial site, and the rapid cooperative motion between the Li-ions at 36f can drop the activation energy of LAGP crystal by decreasing the relaxation energy; furthermore, an energy model was built based on the time-based analysis of Li-ion diffusion to articulate the behavior. The glass and interfacial structure show and accumulation of AlO4, GeO4 and Li at the interface, which explains the Li-trapping on the intergranular glass phase. An in-situ synchrotron X-ray study found …

Members of the elderly population is disproportionately prone to experiencing mobility impairment due to their aging bodies and as a result have frail bodies that are at a higher risk of grave injury due to falling. In order to combat this assistive mobility devices such as exoskeletons have been developed to help patients enhance their range of motion. With additive manufacturing techniques, such as fused deposition modeling (FDM), becoming a more mainstream form of design, the inclusion of lightweight polymers such as nylon 12 as primary construction materials for these devices has increased. In this thesis computer aided design (CAD) software was used to design a prototype lower body exoskeleton and simulation software was used to give the device the characteristics of Stratasys' nylon 12 carbon fiber FDM material to verify it if could be used as the primary construction material for this device when extruded from a FDM printer on either the XZ or ZX printing plane. From the simulations it was found that the material printed along the XZ plane could create a device that could withstand the weight of an average elderly male patient (200 lbs.) as well as the 35 lbs. of force applied to the …

The implementation of professional learning communities (PLCs) has led to systemwide reform within school districts and campuses regarding how campus leaders support the teachers' collaborative work and continued professional learning. Current research emphasizes the importance of campus administrators cultivating an environment where PLCs can flourish and ensuring that PLC teams have the resources to work effectively. However, campus administrators simply putting these supports in place does not make them effective. This study sought to explore campus leader and teacher perceptions of administrator actions that support PLCs for teachers in core-content subjects at two suburban north Texas high schools. An explanatory sequential mixed methods research design was utilized, and three data collections tools were used: an electronic survey, interviews with campus administrators and teachers, and the analysis of campus and PLC artifacts. Survey data indicated that participating teachers had an overall positive perception of the current campus practices which support PLC teams. Teacher interview data revealed that teachers preferred that campus administrators take a neutral role in PLC team meetings, that administrators ensure PLC teams are meeting the established campus PLC expectations, and that administrators observe the team, listen, and ask questions to help the team. Campus administrators viewed their actions …

How do religions and nationalism interact in secular democracies? With its history of nationalism based on religious ideologies, and the subsequent forced separation of state and religion, Japan provides a valuable case to examine how religion and nationalism interact and affect the politics of a secular state. The purpose of this dissertation is to understand and synthesize the divide within the literature regarding the idea that Shinto is fundamentally nationalist in nature. Due to Shinto's historical ties to Japanese nationalism, it is clear that religion and nationalism played a role in Japanese politics in the past. However, with Japan's transition to democracy and the constitutional provision of the separation between religion and state, religion's effect on nationalism in Japan has become blurred contemporarily. In order to explore these relationships between Shinto, nationalism, and Japanese politics, I investigate how political groups and religious organizations influence nationalist sentiment in political institutions and public opinion in Japan using the Japanese Value Orientations survey and an original dataset. I find that even though the evidence is mounting against the accuracy around the idea of State Shinto and the fundamentally nationalist nature of Shinto, the narrative persists. The existence of nationalist circles perpetuates these narratives, …

The dissertation examines factors influencing nonprofit organizations' contribution to collaborative governance for climate change adaptation and nonprofit roles in the collaboration. Why an organization collaborates with others has long been a concern of scholars. However, in a majority of empirical studies, collaboration has been considered as a dichotomous concept. To fill the gap, this study considers organizations' contribution to collaboration, i.e., collaboration level in terms of power, joint activities, human resource, funding, and information sharing. To understand contribution of nonprofits to collaboration for climate change adaptation, this research employs the institutional collective action framework suggesting that organizations work together when expected benefits are greater than collaborative risks. Survey data from 101 nonprofit private organizations (beyoungri mingan danche) in South Korea, which are legally defined in the Assistance for Nonprofit, Nongovernmental Organizations Act, are analyzed. Finding is that government funding and social relationship are strongly associated with nonprofit contribution to collaboration, highlighting that the financial stability of nonprofit organizations and mutual trust among entities based on routine interaction are critical motives for nonprofit collaboration. Finding also reveals that Korean nonprofits mainly play a role as social capital creators in climate change adaptation. The finding also highlights that Sang Bu Sang Jo …

Having a secure attachment to God may act as a buffer against stress. Secure attachment to God has been positively associated with adaptive outcomes following stress, such as higher levels of stress-related growth and fewer maladaptive symptoms including depression, prolonged grief, and traumatic distress. However, relatively few studies have empirically tested the relationship between attachment to God and resilience and posttraumatic growth. Thus, the current study explored the potential associations and pathways through which attachment to God is associated with resilience and posttraumatic growth in a sample of 303 suddenly and/or traumatically bereaved individuals. The current study found that (a) God attachment avoidance is a unique negative predictor of resilience and posttraumatic growth even when controlling for adult attachment, (b) self-compassion and meaning-making mediate the association between God attachment anxiety and resilience/posttraumatic growth, (c) secure attachment to God is associated with higher levels of resilience than insecure attachment styles, but not with posttraumatic growth, and (d) an increased number of secondary losses is associated with lower levels of resilience. I conclude by discussing my findings in light of the extant literature on attachment to God, resilience, and posttraumatic growth. By better understanding attachment to God and how it may relate …

The dissertation seeks to rediscover Julius Schloss, a German Jewish composer victimized by the Nazis. Except for the promising start of his career in his early years, Schloss suffered a hard life as an exiled refugee. However, his unusual experiences inspired him to compose two Chinese Rhapsodies during his last years of exile in Shanghai, in which he synthesized Western composition techniques and Chinese folk materials, amalgamating influences from both Western and Eastern music cultures. Focusing on Schloss's First Chinese Rhapsody, the dissertation explores how Schloss links the new to the old, the West to the East, through an analysis of the way he employs Chinese folk song material and serial polyphonic voice-leading in his post-tonal musical language. Since the Rhapsody has both serial and polyphonic voice-leading aspects, both are analyzed, showing how they are integrated in the form.

The two fields of acousmatic music and site-specific conceptual art take strikingly different approaches to the notions of space and place. In this document, I describe how these two areas of aesthetic research diverge and relate to each other, focusing on how their unique approaches can be implemented in the practice of site-specific music composition. The first part of this document surveys the distinctive features of each of these fields, describing the particular differences between them in their approach to space and place. The contradictions between the two approaches are then briefly analyzed in reference to Georgina Born's understanding of music as fundamentally multitextual. In the second part of the document, I describe in detail how I implemented a site-specific approach when composing "…threaded through," a 16-channel audio, 6 video, site-specific installation for the UNT College of Music Main Building. In this, I describe how both the space and place of the UNT College of Music Main Building influenced my musical choices, visual content, and approach to audio and visual spatialization. The final part of the document contains a detailed score for realizing "…threaded through" in the location of the UNT College of Music Main Building.

In this thesis, I explore the careers and songs of Florence Price and Margaret Bonds—two African American female composers who were part of the Chicago Renaissance. Price and Bonds were members of extensive, often informal, networks of Black women that fostered creativity and forged paths to success for Black female musicians during this era. Building on the work of Black feminist scholar Patricia Hill Collins, I contend that these efforts reflect Black feminist principles of Black women working together to create supportive environments, uplift one another, and foster resistance. I further argue that Black women's agency enabled the careers of Price and Bonds and that elements of Black feminism are not only present in their professional relationships, but also in their songs. Initially, I discuss how the background of the Harlem and Chicago Renaissances and racial uplift ideology shaped these women's artistic environment. I then examine how Bonds and Price incorporated, updated, and expanded versions of these ideals in their music and careers. Drawing on the scholarship of Rae Linda Brown, Angela Davis, and Tammy L. Kernodle, I analyze Price's "Song to the Dark Virgin," "Sympathy," and "Don't You Tell Me No" and Bonds's "Dream Variation," "Note on Commercial Theater," …

The intention of this thesis is to analyze the representations of masculinity in the anime series Dragon Ball Z as it aired on Cartoon Network's programming block Toonami, specifically the nature in which they were framed and how oppositional interpretations in the fandom became prevalent as a result. The series emphasizes the evolution of its central characters Goku, Vegeta, and Gohan into performing a sensitive masculinity, but there are a prevalence of images in the series that discredit this. Similarly, the way the series was advertised on Toonami placed emphasis on images of superficial violence and reinforced the masculinity that the series was attempting to move beyond. Understanding the ways fans have interpreted Dragon Ball Z on Toonami helps reveal that there is much more to a media text's influence than its themes and representations of gender.

In 2016, An estimated 15,000 people representing 400 Indigenous Nations and non-indigenous allies gathered at the Standing Rock Sioux Reservation in solidarity against the Dakota Access Pipeline to protect Mni Sose, the Missouri River. They became known as the Water Protectors. This dissertation analyzes the response in environmental philosophy journals to the #noDAPL protest at Standing Rock. Even though the Stand at Standing Rock became one of the most important and monumental environmental protests of the last decade, neither Standing Rock nor the Water Protectors appear in environmental philosophy journals at all--not once. Why? I suggest a possible answer by exploring the Stand of the Water Protectors as a moment in a much longer continuous history of resistance to settler colonialism. Settler colonialism attempts to facilitate the erasure of Indigenous populations by colonial ones, in order to gain access to territory—to land. The omission of Standing Rock from environmental philosophy journals represents the ease with which environmental philosophy can become complicit in the project of settler colonial erasure and replacement through absence. Drawing on Indigenous land-based philosophies of kinship, Latin American decolonial philosophy, settler colonial theory, and frameworks of Indigenous environmental justice, I show how the geo-politics of colonialism have …
