The Acceptance and Usage Intention of Menstrual Underwear
This research aims to study the consumer perception, acceptance and adoption of menstrual underwear as it provides a sustainable option to the current feminine hygiene management solutions widely used in the consumer market in the U.S. In addition to the functional and utilitarian aspect of the underwear, I further delve into studying the social psychological effect the usage of the underwear (i.e., hedonic) has on consumer adoption. A longitudinal, qualitative study employing a three-step approach was conducted. The findings suggest that participants have never heard of menstrual underwear and did not fully understand the phenomenon. Contradicting responses between subject's attitudes and behavior towards the environment were revealed although, menstrual underwear had a positive psychological effect on the participants. Overall, menstrual underwear was most accepted amongst participants in the study.

An Alternative Operationalization of Betrayal Trauma using Perceived Betrayal
There are many identified factors that correlate with whether an individual experiences adverse symptoms following a traumatic event. Research indicates that betrayal, where the victim is betrayed by another individual, may be one of these factors. Betrayal Trauma Theory (BTT) posits that betrayal during trauma increases the likelihood of developing adverse psychological symptoms. BTT objectively dichotomizes traumas as high betrayal or low betrayal traumas based on details of the event. Though literature finds those who experience high betrayals experience more severe symptoms of PTSD, depression, anxiety, and dissociation than those who experience low betrayals, this objective classification is limited as it is based solely on the circumstances of the trauma and does not give the victim the option of indicating whether they felt betrayed. We believe perceptions of betrayal, whether the event meets the objective criteria of betrayal put forth by BTT or not, is an important predictor of trauma-related outcomes. This study (N = 244) found that perceived betrayal predicts symptoms of PTSD and depression independently, as well as when controlling for objective betrayal, dependence on the perpetrator, event centrality, anxiety, and dissociation. These findings indicate perceived betrayal is a unique construct that should be included in the operationalization …

An Analysis of Dave Holland's Free Improvisation in "Waterfall" and Its Pedagogical Applications for Bassists in Avant-Garde Performance
This research investigates a microcosm of the free jazz/free improvisation environment of the 1970s in "Waterfall," from the album Dave Holland/Sam Rivers Vol. 1. This recording features Dave Holland and Sam Rivers exhibiting highly developed improvisational language and effortless interaction. The purpose of this investigation is to create pedagogical material for bassists who are unfamiliar and/or uncomfortable with performing in an improvisational style that exists separately from the rigid, instrumental role hierarchy of common practice jazz. An analysis of musical elements including melody, rhythm, form, and energy through systems of musical contour, musical forces, and form analysis reveal constituent patterns that can be isolated. These patterns are codified and presented as pedagogical suggestions to assist in the practice of free improvisation.

An Analysis of Student Perceptions of Teaching Effectiveness for Instructors Who Teach the Same Course in the Same Semester in Both Online and Face-to-Face Formats
There is an increasingly number of students taking online classes in lieu of or in addition to the traditional face-to-face format. With this trend, there are questions that naturally come to the surface. The biggest question being "is teaching in the online arena just as effective as the face-to-face arena?" This dissertation aims to pursue that line of questioning by analyzing students' perceptions of the teaching effectiveness for instructors who teach the same course in both an online and face-to-face format in the same semester. The data are analyzed through the lens of the social capital theory. Social capital has never been applied to the classroom before as its focus has traditionally been on community development. However, social capital theory addresses interpersonal relationships and their impact on knowledge sharing behavior. This theory identifies three dimensions, which appear to have a parallel track with the student evaluation components; each is analyzed against each other. These dimensions include structured, cognitive and relational and are compared to the components of the student evaluation tool, which includes organization and explanation of materials, learning environment and self-regulated learning.

Analyzing Learning Acquisition and Retention in a WebVR Environment
The primary purpose of this study was to determine if WebVR enhances the knowledge retention regarding mechanical components of high-risk moving machinery, specifically elevators. There were 23 participants divided into a treatment group and comparison group. The treatment group used WebVR to take a virtual elevator machine room tour while the comparison group studied printed images of the same elevator machine room. These alternative activities were conducted prior to a field trip to a real elevator machine room. Gains in knowledge pre to post were measured and compared between the treatment and comparison groups. The research findings showed an overall gain in knowledge for the participants in the elevator bootcamp. More in depth analysis showed the treatment group exhibited significant gains for six of the ten knowledge areas while the comparison group exhibited significant gains in three of the ten targeted knowledge areas. The treatment group gained more knowledge on components higher than eye-level while the comparison group scored better on components that were below eye-level or on the floor. Both groups were seen actively engaged in the field trips. The treatment group members exposed to the virtual reality elevator machine room frequently referred to what they saw in the …

And the Stereotype Award Goes to...: A Comparative Analysis of Directors using African American Stereotypes in Film
This study examines African American stereotypes in film. I studied six directors, Kathryn Bigelow, Spike Lee, the Russo Brothers, Ryan Coogler, Tate Taylor, and Dee Rees; and six films Detroit, BlacKkKlansman, Captain America: The Winter Soldier, The Help, and Mudbound. Using the framework of critical race theory and auteur theory, I compared the common themes between the films and directors. The main purpose of my study is to see if White or Black directors predominantly used African American stereotypes. I found that both races of directors rely on stereotypes for different purposes. With Black directors, the stereotype was explained further through character development, while the White directors used the stereotype at face value with no further explanation.

Biomedical Semantic Embeddings: Using Hybrid Sentences to Construct Biomedical Word Embeddings and its Applications
Word embeddings is a useful method that has shown enormous success in various NLP tasks, not only in open domain but also in biomedical domain. The biomedical domain provides various domain specific resources and tools that can be exploited to improve performance of these word embeddings. However, most of the research related to word embeddings in biomedical domain focuses on analysis of model architecture, hyper-parameters and input text. In this paper, we use SemMedDB to design new sentences called `Semantic Sentences'. Then we use these sentences in addition to biomedical text as inputs to the word embedding model. This approach aims at introducing biomedical semantic types defined by UMLS, into the vector space of word embeddings. The semantically rich word embeddings presented here rivals state of the art biomedical word embedding in both semantic similarity and relatedness metrics up to 11%. We also demonstrate how these semantic types in word embeddings can be utilized.

Biopedagogy of Rumination and Regurgitation
Regurgitating test answers, needing more time to digest a reading, or being spoon fed information are just a few of many digestive metaphors currently used in education. In taking seriously the use of these metaphors, I suggest that humans recognize a connection, on some level, between the mental act of taking in and processing knowledge and the physical act of digestion, yet in educational discourse, these processes are more often than not cast in a negative light. The following philosophical exploration begins with a close look at two digestive practices, rumination and regurgitation, in non-human animals such as ruminants, seed-eating birds, and honey bees. By looking to these animals, it becomes possible to rehabilitate an affirmative human version of rumination and regurgitation in which our physical and mental selves are intrinsically intertwined in and through bodily education. The works of Giorgio Agamben, Tyson E. Lewis, Nathan Snaza, and Vinciane Despret support a theoretical framework which moves beyond human-centered education towards the development of an inhuman biopedagogy that embraces digestion rather than discriminates against it. I offer practical applications of rumination and regurgitation, shedding light on moments when rumination and regurgitation are already present in education, and introduces slight adjustments to …

A Case Study of Leadership Supports of Job-Embedded Professional Development
Professional development is a critical part of school improvement and enhancing teacher quality; yet there is limited literature about how principals design and lead effective professional development systems. The research activities in this qualitative single case study explored the leadership practices at one successful school implementing job-embedded professional development. A conceptual framework relating Hallinger's leadership for learning construct to professional development helped frame the research. Collected data included participant interviews, a focus group interview, observations, and relevant document analysis. These data were analyzed using a general inductive method to identify the prevailing leadership characteristics. The major themes that emerged during analysis were: (a) vision and goals, (b) high expectations, (c) structures and resources, (d) communication, (e) monitoring progress and providing recognition, (f) focused and ongoing professional development, (g) differentiated professional development, (h) trust and professionalism, (i) culture of learning and growth, (j) building capacity, and (k) collaboration. These themes aligned well with the initial conceptual framework. These findings support the concept that leadership for learning may have implications for school leaders trying to implement effective job-embedded professional development.

Characterization, Analysis, and Optimization of Rotary Displacer Stirling Engines
Access:
Use of this item is restricted to the UNT Community
This work focuses on an innovative Rotary Displacer SE (RDSE) configuration for Stirling engines (SEs). RDSE features rotary displacers instead of reciprocating displacers (found in conventional SE configurations), as well as combined compression and expansion spaces. Guided by the research question "can RDSE as a novel configuration achieve a higher efficiency compared to conventional SE configurations at comparable operating conditions?", the goal of this study is to characterize, analyze, and optimize RDSE which is pursued in three technical stages. It is observed the RDSE prototype has an optimum phase angle of > 90° and thermal efficiency of 15.5% corresponding to 75.2% of the ideal (Carnot) efficiency at the source and sink temperatures of 98.6° C and 22.1° C, respectively. Initial results indicate that 125° phase angle provides more power than that of the theoretically optimum 90° phase angle. The results also show comparable B_n and significantly higher W_n values (0.047 and 0.465, respectively) compared to earlier studies, and suggest the RDSE could potentially be a competitive alternative to other SE configurations. Furthermore, due to lack of a regenerator, the non-ideal effects calculated in the analytical approach have insignificant impact (less than 0.03 kPa in 100 kPa). The clearance volume in …

Child-Centered Canine-Assisted Therapy: An Investigative Look at Integrating Therapy Dogs into Child-Centered Play Therapy
Play therapy and animal-assisted therapy are two specialized modalities within the field of counseling. Child-centered play therapy (CCPT) is a specific theoretical approach to play therapy that regards the therapeutic relationship as the primary healing factor. With much empirical support, CCPT is considered an effective mental health treatment option for working with children. Animal-assisted therapy in counseling (AAT-C) is acknowledged in the literature as a supplemental treatment modality to an existing counseling practice. Although past researchers have shown support for AAT-C as well as CCPT, there is a current dearth of literature examining the integration of these approaches. The present study sought to understand the approach of incorporating a therapy dog into child-centered play therapy while maintaining theoretical consistency. Using a constructivist grounded theory approach, I facilitated child-centered canine-assisted play therapy (C3APT) services for four children and reviewed the sessions with expert supervisors in AAT-C and CCPT. Three major themes emerged from the data: (a) principles of C3APT, (b) procedures of C3APT, and (c) relational dynamics. Implications for clinical practice and training of both therapy dogs and C3APT practitioners are also discussed.

Computational Development of Trimetallic Cyclotrimers for Gas-Filtration Applications through Non-Covalent Interactions
Access:
Use of this item is restricted to the UNT Community
Photophysical properties of an array of various polyaromatic hydrocarbons were benchmarked with B3LYP, M06 and B97D methods coupled with Pople and CEP-31G(d) basis sets. Results from the benchmark show the importance of diffuse basis sets when modeling the electronic properties of highly conjugated systems and provide qualitative reliable accuracy with certain levels of theory. B97D and M06 are applied to modeling pyrene adducts governed by non-covalent interactions in both gaseous and condensed states to reproduce experimental spectra. DFT calculations with both B97D and M06 functionals show qualitatively and quantitatively that pyrene dimer is a stronger π–base as compared to its monomer. Binding energies coupled with MEP, PCA and Qzz results show that the difference in π-basicity of the monomer and dimer impacts the supramolecular chemistry involved in adducts formed with super π-acidic silver cyclometallic trimer (CTC). Non-covalent interactions between coinage metal CTCs and ammonia/phosphine substrates is reported. Interactions between these substrates and the facial plane of the π-rich gold CTC reveal a novel interaction, where the typical Lewis acid/base roles are reversed for the substrates. Adducts formed through this type of interaction define typical Lewis bases like ammonia and phosphine as Lewis acids, wherein the partially positive hydrogens coordinate to …

Conceptual Barriers to Decarbonization in US Energy Policy
In order to meet emissions targets under the UN Paris Agreement, every nation must decarbonize its energy production. The US isn't reducing energy-related emissions fast enough to meet its targets for keeping overall warming under 2°C above pre-industrial levels. This constitutes a grave injustice to the most vulnerable populations of the world, who are suffering the ill effects of climate change already. The challenge of eliminating fossil fuels from the US energy system is not simply one of technological limitations, however. The aim of this dissertation is to provide an analysis of historical, political, and, most importantly, conceptual barriers to decarbonization of energy in the US. I believe not just our policies and our markets, but our thinking has to change if we are to avoid recapitulating the injustices of the fossil fuel energy system. I argue that energy policy in the US over time has ossified around a narrow conception of energy as fossil energy—as a substance, rather than as a service. I call this the fossil conception of energy (FCE). I follow historical traces of the FCE in three key areas: political discourse in the US, the relationships between the US dollar and OPEC oil (a complex web …

Creating the Character of North Texas: Demographics and Geography, 1841-1861
Several historians have identified North Texas as constituting a unique cultural region in antebellum Texas, due to the more limited cotton and slave economies and greater opposition to secession. Different settlement patterns have been put forward as an explanation for the distinct "character" of North Texas, with North Texas being portrayed as being settled largely by migrants from the Upper South while the rest of the state was primarily settled by Lower Southerners. The argument rests on the assumption of differing economic and political cultures between Upper and Lower Southerners. This study investigates migration into North Texas counties and the economic life and secession vote in those counties. It challenges the simplistic dichotomy between migrants from the Upper and Lower South by demonstrating the similar rates at which these two groups grew cotton and owned slaves. It also illustrates how geographic considerations better explain the apparent distinctions between North Texas and the rest of the state. Transportation limitations are likely the reason for the more limited cultivation of cotton and, consequently, the lowered importance of slavery in North Texas. Concerns about Indian depredations following the removal of federal troops in the case of secession also seem to have promoted Unionist …

Creative Networks: Toward Mapping Creativity in a Design Classroom
This study developed new mapping techniques and methodologies for understanding creativity in terms of connectivity and interaction between human and non-human actors in a design classroom. The researcher applied qualitative methods of data collection combining both observation of classroom activities and focus group interviews in order to map a creativity network. The findings indicate that creativity is a complex weather-like system (or what I call "creative climate") composed of many sub-networks and diffused networks. Four interactions emerged from the study: (a) the creative climate is composed of the circulation of bodies and objects forming networks and sub-networks, (b) centers and corners/edges are a measure of connectivity and interaction in classroom space design, (c) roundness is a measure of classroom style and the space of connectivity usage, and (d) plugs-in creativity is a measure of technology consolidation. This study attempted to fill the gap in the literature on creativity and classroom design by explaining the role of non-human actors in shaping the creative climate in the classroom, especially the role of the classroom space itself as an actor. The implication of this study in art education opens a new opportunity for research in designing innovative classrooms. Also, it will allow future …
