Analysis of Sensory Integration Techniques on Automatically Maintained Problem Behavior

Sensory integration techniques are a common treatment procedure among occupational therapists. The goal is to "apply" input that competes with input from problem behavior. Although this is a commonly recommended intervention, there is limited empirical evaluation with adults with intellectual disabilities. Therefore, we evaluated the effectiveness of occupational therapist-suggested sensory stimuli on the automatically maintained problem behavior of adults. Specifically, we compared the effects of non-contingent access to sensory stimuli and non-contingent access to highly preferred stimuli on the rate of problem behavior. Results suggested that, relative to highly preferred stimuli, sensory stimuli had either a limited effect on problem behavior, or in some cases, were correlated with increases in problem behavior. This suggests that sensory stimuli may not produce the same automatic stimulation as problem behavior. We will discuss implications for treatment, including methods for better identifying stimuli for use in the treatment of automatically maintained problem behavior.

Analyzing the Joint Effects of Network and Community Attributes on Network Performance: Evidence from Local Continuum of Care Homeless Service Networks

This dissertation examines the factors and combinations of factors that affect the performance of continuum of care homeless service networks, applying the configurational approach of contingency theory to data sets drawn from federal sources. The study accepts the two key assumptions from the theory: (1) that there are multiple paths to high performance and (2) key conditions have a joint influence on network performance. The data analysis in this study has two parts. The first employs OLS regression to examine the causal relationship between independent variables and the performance of permanent supportive housing (PSH) programs. This study also applies fuzzy set qualitative comparative analysis (fsQCA) to identify multiple combinations of factors that influence the performance of PSH programs. The results identify key factors and multiple combinations of factors that lead to high and low network performance. Federal CoC funding emerges as a core condition for high and low performance, but all relevant conditions can be critical factors depending on how they interact with other relevant conditions. This analysis helps expand the utility of existing contingency theory by using it to explain the dynamic interactions between factors in the context of public service networks. Ultimately, this dissertation confirms that fsQCA can …

Are We Zwisch-ing Yet? An Examination of the Zwischenfach Voice Category and Selected Twenty-First Century American Arias

The German word Zwischenfach often refers to opera roles and singers whose voices lie between the categories of mezzo-soprano and soprano. While the term is not universally accepted as a voice category, Zwischenfach voices and roles are being discussed more openly and with more specificity in collegiate and professional circles. This document includes a discussion on the challenges of categorizing dramatic voices, mezzo-soprano voices, and those who could be considered Zwischenfach, taking into consideration the inherent ambiguity and flexibility within these voice categories. The elements that have led to developmental changes in opera voices and their categories over the centuries provide insight and context on how Zwischenfach has become a term that describes the ambiguity and challenge of classifying opera voices in the twenty-first century. A main focus of this document is a discussion of eleven pieces from twenty-first century American operas which a Zwischenfach singer could consider for auditions and performances. Operas included are: Dead Man Walking by Jake Heggie, The Grapes of Wrath by Ricky Ian Gordon, After Life and Glory Denied by Tom Cipullo, Lysistrata by Mark Adamo, Dinner at Eight by William Bolcom, and Fantastic Mr. Fox by Tobias Picker. My hope is that this document …

Avian Community Response to Riverby Ranch Restoration Reconstruction

Anthropogenic activities have caused many wildlife spices to decline in populations worldwide. The grassland bird communities are especially being impacted by these land use changes. Breeding success is closely tied to functional habitats for most grassland bird species in North Texas. Restoring these degraded habitats is an important component to aid in conserving wildlife biodiversity. We surveyed the bird population at Riverby Ranch Mitigation site by conducting point count sampling. This site consists of recently restored grassland, wetland, and forested habitat. This research was focused on conducting post restoration monitoring of the bird community in the early succession of the restored habitats. We set out to use the bird community as biomonitors to help assess if the restoration practices could be considered successful. We found that density estimates were more than double at the restored site when comparing to three different references sites under different management practices. This included an unrestored working ranch, a wildlife management area, and a conservation managed prairie site. We found that biodiversity metrics were as high or higher than the reference sites. In addition, we also found that there were more observations of species of high conservation concern present at the restored stie. This research …

Bottom-Up Impacts of Grazing Disturbance on Ground-Nesting Bee Assemblages: Do They Dig It?

In my thesis, I examined impacts of nesting and floral resources on ground-nesting bee assemblages at nine ranch sites with differing grazing histories. Because ecological disturbances can strongly affect the availability of foraging and nesting resources over time, I also examined the impacts of grazing history on nesting and floral resources for ground-nesting bees. I sampled bee assemblages, a comprehensive array of vegetation and soil measures, and floral abundance and richness. I used these data to determine (1) the importance of different nesting habitat resources and livestock grazing history for ground-nesting bees and (2) how livestock grazing history influenced the availability of nesting and floral resources. I found that sites with sandier soils had greater abundance and richness of ground-nesting bees, and sites with less compacted soils had greater bee abundance. Contrary to many other studies, the availability of bare ground was not important for ground-nesting bee abundance or richness. Grazing history did not affect any measures of nesting or floral habitat, and had negligible effects on ground-nesting bee abundance, richness, and community composition. My results suggest that the availability of sandier or less compacted soils may be limiting for ground-nesting bee abundance or richness, especially in areas with predominately …

Climate Injustice and Commodification of Lives and Livelihoods in Southwest Coastal Bangladesh

Just and equitable responses to the disparate impacts of climate change on communities and individuals throughout the world are at the heart of the concept of climate justice. Commodification, in the context of my research, is the process of monetizing nature and livelihoods for the purpose of surplus accumulation and profit maximization. In this study, my aim was to contextualize the concepts of climate injustice, disaster capitalism, and the commodification of lives and livelihoods in the specific setting of disaster vulnerability in southwest coastal Bangladesh. By conducting a case study in Kamarkhola and Sutarkhali regions of southwest coastal Bangladesh, I utilized discourse analysis and content analysis of livelihood interviews, semi-structured interviews, and policy documents to demonstrate the conceptual interrelation among global climate change, climate injustice, disaster capitalism, and capitalist expansion in environmentally precarious areas. I argue that in Southwest Coastal Bangladesh, the vulnerability to disasters stems from a complex and multifaceted layer of social hierarchies and inequalities, entwined with factors such as class and power relations. I also argue that Inequalities in the political, economic, and social realms have a key role in imposing vulnerability on disadvantaged people living in ecologically vulnerable areas. The perpetuation of inequality is sustained by …

A Comprehensive Investigation of Photoinduced Electron Transfer and Charge Transfer Mechanisms in Push-Pull Donor-Acceptor Systems: Implications for Energy Harvesting Applications

Donor-acceptor systems exhibit distinctive attributes rendering them highly promising for the emulation of natural photosynthesis and the efficient capture of solar energy. This dissertation is primarily devoted to the investigation of these unique features within diverse donor-acceptor system typologies, encompassing categories such as closely covalently linked, push-pull, supramolecular, and multi-modular donor- acceptor conjugates. The research encompasses an examination of photosynthetic analogs involving compounds such as chelated azadipyromethene (AzaBODIPY), N,N-dimethylaminophenyl (NND), phenothiazine (PTZ), triphenylamine (TPA), phenothiazine sulfone (PTZSO2), tetracyanobutadiene (TCBD), and expanded tetracyanobutadiene (exTCBD). The strategic configuration of the donor (D), acceptor (A), and spacer elements within these constructs serves to promote intramolecular charge transfer (ICT), which are crucial for efficient charge and electron transfer. The employment of cutting-edge analytical techniques, such as ultrafast transient absorption spectroscopy, is integral to the study. Furthermore, a comprehensive suite of analytical methodologies including steady-state UV-visible absorption spectroscopy, fluorescence and phosphorescence spectroscopies, electrochemical techniques (including cyclic voltammetry and differential pulse voltammetry), spectroelectrochemistry, and density functional theory calculation (DFT), collectively contribute to the comprehensive characterization of push-pull donor-acceptor systems, with a particular emphasis on their potential as highly effective solar energy harvesting application.

Decoding Fantasy: An Analysis of Paquito D'Rivera's "Caribbean Berceuse" (2021)

Written for and featuring the Barcelona Clarinet Players, Caribbean Berceuse (2021) is Paquito D'Rivera's (b.1948) first composition for wind band. Along with idiosyncratic expectations of fusing jazz and classical elements according to D'Rivera's oeuvre, the title implies extramusical associations in the composition. This analysis demonstrates how extramusical associations interact with thematic development by using five codes of meaning from Roland Barthes's (1915–1980) S/Z (1970), which was first applied to music by Patrick McCreless. In addition to D'Rivera's cultural references, this composition involves musicians from many different cultures and backgrounds: the Barcelona Clarinet Players of Spanish heritage, Paquito D'Rivera of Cuban heritage, and the North Texas Wind Symphony under the direction Eugene Migliaro Corporon as an American melting pot. My analysis demonstrates how D'Rivera incorporates shared experiences of a lullaby as an access point for listeners. Our experience of falling asleep creates dichotomous structures of reality and fantasy, of time and memory, and sometimes of a restless lullaby among others. Roland Barthes places the most importance on these extrinsic dichotomous structures as deeper meanings of referential associations. He names this symbolic code. Although McCreless places less importance on symbolic code as correlating to music, my analysis will demonstrate how the interaction …

The Effect of Developmental Hypoxia on Cardiac Physiology in Three Species: Alligator mississippiensis, Chelydra serpentina, and Danio rerio

In this dissertation, I explored the effects of developmental hypoxia on heart contractility in three separate species of ectotherms: the common snapping turtle (Chelydra serpentina), the American alligator (Alligator mississippiensis), and the zebrafish (Danio rerio). I began with the common snapping turtle and tested whether the utilization of the sarcoplasmic reticulum was altered in response to developmental hypoxia. In the next two chapters, developmental hypoxia of the American alligator was explored studying how the cardiac tissue was affected, specifically in physiological stressors, sarcoplasmic reticulum utilization and sensitivity to pharmacological increases in contractility. The last chapter explored how zebrafish heart contractility was altered in response to chronic hypoxia from egg to adult. Findings from these chapters suggest that while developmental hypoxia did alter cardiac contractility, it did not alter the response of the heart to physiological stressors such as increased heart rate or under hypoxia. Overall, these findings contribute to increasing the current understanding of how developmental hypoxia alters the cardiovascular system but with an emphasis on the cardiac tissue level.

The Effect of Restructuring of Peer Firms on Investment

Firms' operational restructuring involves information relevant to strategic choices as well as future demand and cost conditions. This study examines the relationship between peer firms' restructuring and a company's responsiveness to its growth opportunities. Peer firm restructuring can increase uncertainty with respect to a company's payoffs regarding its investment projects, leading to decreased responsiveness to growth opportunities. Using a large sample of public companies during 2006–2020, I find that peer firms' restructuring is negatively associated with the responsiveness of capital expenditures (Capex) to growth opportunities. The results suggest that peer firms' restructuring activities provide information about a company's investment projects above and beyond industry shocks reflected in changes in industry sales. Furthermore, these associations are moderated by industry competition. The negative effects of peer firms' restructuring on Capex sensitivity are the strongest in high-competition industries.

The Emergence of Arab Nation-State Nationalism as an Alternative to the Supranational Concept of Ummah

In this dissertation, I examine the political shift or reorientation of Arabs and Muslims from the supranational Ummah to the Western form of nation-state by attending to modern Arabic novel in the period between World War I and World War II. I explore the emergence of secularism in Arab national formation. One of my central arguments is that Arab nationalism is indeed a misleading phrase as it gives the impression of unity and coherence to a complex phenomenon that materialize in a number of trends as a form of struggle. In the first chapter, I defined the scope of my argument and the underlying structure and function of nationalism as a form of representation masked by nationalist ideologies. To investigate the reorientation of Arabs and Muslims from Ummah to adopting nation-state, I utilize Spivak's criticism of the system of representation along with Foucault's theorization of discourse. I argued along Edward Said that although the Western national discourse might have influenced the Arab nationalists, I do not believe they prevented them from consciously appropriating nationalism in a free creative way. I also explained that the Arab adoption of a secularist separatist nationalism was more an outcome than an effect in the …

Examining the Educational Depth of Medical Case Reports and Radiology with Text Mining

The purpose of this dissertation was to use the technology of text mining and topic modeling to explore unobserved themes of medical case reports that involve medical imaging. Case reports have a valuable place in medical research because they provide educational benefits, offer evidence, and encourage discussions. Their form has evolved throughout the years, but they have remained a key staple in providing important information to the medical communities around the world with educational context and illuminating visuals. Examining medical case reports that have been published throughout the years on multiple medical subjects can be challenging, therefore text mining and topic modeling methods were used to analyze a large set of abstracts from medical case reports involving radiology. The total number of abstracts used for the data analysis was 68,845 that were published between the years 1975 to 2022. The findings indicate that text mining and topic modeling can offer a unique and reproducible approach to examine a large quantity of abstracts for theme analysis.

Horses Against Tanks: Historical Memory and the German Invasion of Poland

The entrance of the German Invasion of Poland and depiction thereof into modern historiographical conversations offers historians superior articulation of the creation of historical memory, mythos, and identity ‒ especially in wider terms of European Imperialism. By utilizing the current trends in gendering of empire, the use of auto-biography and life writing to understand felt realities and obfuscated truths, and the attempts by empire to queer and utilize labeled deviations to control and gain power over their colonized subjects, one is presented a better understanding of how the German Invasion of Poland fits into the story of empire and indigeneity. That story continues past the Third Reich however, as German propaganda in its various forms was accepted as truth after the Second World War, providing justification for and rationalizing post war political power structures of Western nations. As the threat of a cold war with the USSR loomed, many in the American military felt it necessary to accept and support German myths about their military prowess (and non-culpability for the Holocaust) and the inferiority of Slavic military forces. By analyzing not the myths themselves, but how they were created and propagated, historians can add to this historical conversation a case …

The Idiomatic Techniques and Procedures of Composer Kevin Walczyk (b. 1964) that Define a Unique Musical Language

Award winning composer Kevin Walczyk's describes himself as a "musical storyteller," using all musical elements of structure, melody, harmony, and counterpoint to convey programmatic content. A variety of subjects are conveyed that include historical events, people, physical objects or locations, and literary texts. Deeper matters, such as spiritual themes, are also often incorporated in his music that enhance the musical program. The technical procedures employed—pertaining particularly to the expression of programmatic content—has produced a unique musical language that stands out in the modern compositional landscape. What are these inherent idiomatic features, and how are they exhibited? The purpose of this dissertation is to provide a detailed examination of Walczyk's distinct musical language. A critical analysis of the technical procedures used to convey his programmatic content, as well as insights into his influences and writing process, illuminate the attributes of this a posteriori musical language. The two works selected for this study to demonstrate this are Symphony No. 2: Epitaphs Unwritten and Talking Winds, both written for wind band.

Kinetics and Thermochemistry of Halogen and Nitrogen Compounds

Halogen and nitrogen containing compounds play a key role in the atmospheric chemistry of the Earth. Through a mixed computational and experimental approach, the kinetics of these compounds with radicals common to the atmosphere have been explored. Using fundamental measurements such as the IR absorption cross-section, the rate constants of atmospheric reactions and the properties of product molecules have been derived. These results have been further extended to environmental applications such as the Global Warming Potential for a species. The present results can be used as a calibration for further experiments and as checks on computational predictions of environmental properties. Such modeling can aid in the development of future industrial reagents that are less hazardous to the atmosphere.

The Local Organization of Refugee Service Provision: A Qualitative Comparison of Two Resettlement Cities in Texas

This comparative case study examines the organizational variations in refugee services in Dallas and Amarillo, Texas. Engaging sociological theories of organizations, migration, and the state, this study conceptualizes immigrant-serving organizations as brokers that operate within fields of similar entities that channel resources and services to refugees. Drawing on 60 in-depth interviews and over two hundred hours of participant observation, this study finds two distinct models of resource brokerage. In Dallas, immigrant-serving organizations operated as networked resource brokers, characterized by high levels of collaboration, robust local political support, and community engagement through consistent volunteer labor. These characteristics facilitated the sharing of resources and knowledge, resulting in the establishment of more professionalized services for immigrants and refugees. In contrast, immigrant-serving organizations in Amarillo operated as atomized resource brokers, characterized by fragmented collaborations, inter-organizational competition, limited volunteer labor, and varying levels of political support from local representatives. This atomized brokerage model hindered the efficient allocation of resources and support, leading to fragmented and less comprehensive services for refugees. In conclusion, this study provides valuable insights into the variations within the organizational fields of ISOs in Texas. The comparative analysis of Dallas and Amarillo offers a nuanced understanding of the impact of local context …

A Mixed Methods Study of Online Social Comparison and Impostor Phenomenon in Undergraduate Music Education Students

The purpose of this study was to investigate online social comparison and impostor phenomenon (IP) in undergraduate music education students. I employed a sequential explanatory mixed models design to explore the extent to which music education students experienced IP, used Facebook, and engaged in social comparison on Facebook. I explored participants' perceptions of how they engaged in online social comparison in the context of their professional lives. In Phase 1, I surveyed participants to measure impostor phenomenon, Facebook intensity, and Facebook social comparison. Analysis of the descriptive data revealed that 77.8% of participants experienced frequent to intense IP symptoms. Facebook social comparison emerged as the only significant predictor of IP in participants accounting for 13.3% of the variance in CIPS scores. In Phase 2, I conducted focus groups to investigate participants' perceptions of how they engaged in online social comparison as related to their professional identity. The themes that emerged from the qualitative data included: (a) comparing to peers online, (b) using Facebook for professional purposes, (c) psychological effects of online comparison, and (d) withdrawing from social media to avoid adverse effects. Lastly, I integrated the quantitative and qualitative data to expound upon and confirm findings in each phase. The …
