Aquiline Books at UNT: A Progress Report

Description: Presentation for the 2017 Texas Conference on Institutional Repositories. In June 2015, the UNT Libraries launched a for-fee service for publishing works of scholarship from authors affiliated with the university. While authors can choose from a menu of editing and design options, all publications are made free to read online through the institutional repository. In this presentation, we reflect on our choices in designing the publishing service—such as not organizing peer review, delivering publications through the repository, requiring free public access but not Creative Commons licenses—and on what authors have chosen from the menu of options over the past two years.

Academic Stress in Student-Athletes

Description: Academic stress and the causes of such stress are subjects that are found in very few studies concerning student-athletes. Therefore, the purpose of this quantitative study is to determine how the following variables relate to academic stress and perceived stress either through correlations or differences--demographics, academic classification, major or field of study, athletic scholarship status, and season of sport (in- season/ out of season). An online questionnaire containing a Perceived Stress Scale and a Perception of Academic Stress scale were distributed to 151 student-athlete participants at a university in the southwest United States. The results indicated that biological sex has a significant relationship to perceived stress. No other variables were found significant to perceived stress or academic stress.

Adrenergic and Cholinergic Regulation of Cardiovascular Function in Embryonic Neotropic Cormorants (Phalacrocorax basilianus)

Description: Investigations of cholinergic and adrenergic tone on heart rate (fH) and mean arterial pressure (Pm) during embryonic development have been conducted on numerous avian species. While these investigations have documented that adrenergic tone, a continuous stimulation, on fH and Pm is vital to embryonic development in the birds studied to date, development of cholinergic tone on fH has been shown to vary even within species. Further, past studies have been bias to focus primarily on precocial species while altricial species remain poorly understood in this context. The goal of this investigation was to investigate the role of cholinergic and adrenergic tone on fH and Pm of an altricial species, the neotropic cormorant (P. brasilianus) to address this bias. The embryonic neotropic cormorant possesses B-and-a adrenergic tone on fH and Pm at 70% and 90% incubation while cholinergic tone on fH occurs at 90% incubation. This pattern of control is similar to that previously reported for several species of precocial birds suggesting the development of tonic cardiovascular regulation may be conserved across avian taxa.

An Analysis of Litigation against Kansas Educators and School Districts under the Kansas Tort Claims Act

Description: This dissertation examines the significance of the Kansas Tort Claims Act of 1979 on state of Kansas court decisions in litigation against Kansas school districts and their employees. Through providing a historical perspective of the adoption and abolishment of the doctrine of sovereign immunity in the United States, which subsequently led to the enactment of the Federal Tort Claims Act, and ultimately led to the Kansas Tort Claims Act, the researcher analyzes pertinent case law and scholarly commentary pertaining to school negligence litigation. The goal of the analysis is to answer the following research question: How have Kansas state courts interpreted the Kansas Tort Claims Act in litigation against state school districts and their employees? Although the KTCA provides citizens with a vehicle for redress against governmental entities by virtue of tort claims, the KTCA also provides immunities from liability for governmental entities and their employees under exceptions to the KTCA. Most notably, the discretionary function exception and the recreational use exception are two exceptions to liability applied in a significant number of tort cases against Kansas school districts and employees. The case law analysis provides explanations for the types of actions of negligence that Kansas courts have qualified for school district or school employee liability, and, when permitted, negligent actions that qualified for immunity under a KTCA exception to liability.

Application of High Entropy Alloys in Stent Implants

Description: High entropy alloys (HEAs) are alloys with five or more principal elements. Due to these distinct concept of alloying, the HEA exhibits unique and superior properties. The outstanding properties of HEA includes higher strength/hardness, superior wear resistance, high temperature stability, higher fatigue life, good corrosion and oxidation resistance. Such characteristics of HEA has been significant interest leading to researches on these emerging field. Even though many works are done to understand the characteristic of these HEAs, very few works are made on how the HEAs can be applied for commercial uses. This work discusses the application of High entropy alloys in biomedical applications. The coronary heart disease, the leading cause of death in the United States kills more than 350,000 persons/year and it costs $108.9 billion for the nation each year in spite of significant advancements in medical care and public awareness. A cardiovascular disease affects heart or blood vessels (arteries, veins and capillaries) or both by blocking the blood flow. As a surgical interventions, stent implants are deployed to cure or ameliorate the disease. However, the high failure rate of stents has lead researchers to give special attention towards analyzing stent structure, materials and characteristics. Many works related to alternate material and/or design are carried out in recent time. This paper discusses the feasibility of CoCrFeNiMn and Al0.1CoCrFeNi HEAs in stent implant application. This work is based on the speculation that CoCrFeNiMn and Al0.1CoCrFeNi HEAs are biocompatible material. These HEAs are characterized to determine the microstructure and mechanical properties. Computational modeling and analysis were carried out on stent implant by applying CoCrFeNiMn and Al0.1CoCrFeNi HEAs as material to understand the structural behavior.

Applied Use of Video Modeling in Educational and Clinical Settings: A Survey of Autism Professionals

Description: Individuals with autism spectrum disorder (ASD) display deficits in communication and social interaction that can impact their ability to function in daily environments. To remediate these deficits, it is critical for professionals to use effective interventions. While there are many evidence-based practices (EBPs) identified for ASD (e.g., video modeling), the adoption of these EBPs may not occur automatically. Existing research suggests professionals have a generally favorable impression of video modeling. However, little research has examined opinions and applied use of video modeling, which was the purpose of the present study. Using survey methodology, data were collected from 510 professionals in various disciplines (e.g., special educators, speech-language pathologists [SLPs], and behavior analysts [BCBAs]). Data were analyzed primarily via factor analysis and multiple regression. Factor analysis was used to examine the underlying structure of the instrument, revealing two predominant factors: (1) interest in and (2) perceived accessibility of video modeling. Multiple regression was used to examine which demographic characteristics (e.g., age and years of experience) were associated with each factor. Results indicated that BCBAs and SLPs perceived video modeling as more accessible. In terms of interest, professionals who worked with preschool-aged students, who worked in a suburban location, and who had an extended family member with ASD showed higher interest in video modeling. Implications for practice and future research are discussed.

An Argument in Favor of the Saxhorn Basse (French Tuba) in the Modern Symphony Orchestra

Description: The French tuba was a much-needed addition to the brasswind musical instrument family, adding depth, projection and a unique color to French orchestral literature. Its ancestors the serpent and ophicleide both lacked the tonal stability and sonic power to adequately present the bass wind role in a robust orchestra. Through the efforts of its developer and patent-holder Adolphe Sax, the French tuba made converts among players and composers, effectively creating its own niche in music history. Musical tastes change however, and the French tuba has been largely supplanted by tubists using instruments twice its size. Since French composers composed specifically with the distinct timbre of the French tuba in mind, this unique and characteristic musical entity deserves a resurgence in performances of French orchestral repertoire.

Artistic Decision Making and Implications for Engaging Theatrically Gifted and Talented Students in Non-Arts Classes

Description: This cognitive ethnographic study explored the mental processes that professional actors used when making artistic choices while engaged in creative practices to begin a conversation about how the theatrically gifted and talented population is viewed, researched, and educated in non-arts subjects. Professional actors at two sites were observed, videotaped, and interviewed over several rehearsals during play production. The major thematic findings indicated that artistic decision making results from actors engaging in a cyclical process of private work, affective validation, and collaboration. Implications for teaching theatrically gifted students call for classroom environments and processes that echo theatrical rehearsal structures, while engaging the imagination through personal connection and discovery.

Assessing Rainfall Interception by Urban Tree Canopies in Denton, Texas

Description: Rainfall interception is one mechanism by which tree canopies can reduce surface runoff in urban areas. The objectives of this research were to: 1) quantify rainfall interception by urban tree canopies, and 2) determine the influence of vegetation and microenvironmental factors on rainfall interception rates. In the city of Denton, Texas, 30 mature post oak (Quercus stellata) and blackjack oak (Quercus marilandica) trees were selected for study. Trees were assigned to one of three categories: clusters of trees on greenspace (CG), isolated trees on greenspace (IG), and isolated trees surrounded by pavement (IP). Throughfall (the volume of water that travels through the canopy and reaches the soil surface) collectors were placed beneath these trees and rainfall collectors were placed in nearby open areas. Throughfall and rainfall were collected daily from 19 March to 4 July. Interception was calculated as the difference between throughfall and gross rainfall. Over the study period, there were 27 days with measurable rainfall; daily rainfall ranged from 1-51 mm. Over the sampling period, rainfall interception for individual trees ranged from -10% to 49%, indicating high spatial variability in interception. Percent interception was highest for the CG treatment (22.7 ± 3.8 SE), intermediate for IG (27.4 ± 2.3 SE), and lowest for IP (9.1 ± 4.9 SE). Factors like wind exposure, wind-driven rain and overall tree health may help explain this variability. This research will contribute to our knowledge of hydrological fluxes in urban areas and the role of urban green infrastructure in stormwater runoff mitigation.

Automated GUI Tests Generation for Android Apps Using Q-learning

Description: Mobile applications are growing in popularity and pose new problems in the area of software testing. In particular, mobile applications heavily depend upon user interactions and a dynamically changing environment of system events. In this thesis, we focus on user-driven events and use Q-learning, a reinforcement machine learning algorithm, to generate tests for Android applications under test (AUT). We implement a framework that automates the generation of GUI test cases by using our Q-learning approach and compare it to a uniform random (UR) implementation. A novel feature of our approach is that we generate user-driven event sequences through the GUI, without the source code or the model of the AUT. Hence, considerable amount of cost and time are saved by avoiding the need for model generation for generating the tests. Our results show that the systematic path exploration used by Q-learning results in higher average code coverage in comparison to the uniform random approach.
