They Called Him Buckskin Frank: The Life and Adventures of Nashville Franklyn Leslie

Description: Nashville Franklyn “Buckskin Frank” Leslie was a man of mystery during his lifetime. His reputation has rested on two gunfights—both in storied Tombstone, Arizona—but he was much more than a deadly gunfighter. Jack DeMattos and Chuck Parsons have combined their research efforts to help solve the questions of where Leslie came from and how he died. Leslie developed a reputation as a man to be left alone. Such notables as the Earps, Doc Holliday, and John Ringo wisely avoided confrontations with him. Leslie was a “lady killer” both figuratively and—in one celebrated incident—literally. Beyond his gunfighting legacy, DeMattos and Parsons also explore Leslie’s scouting with General Crook on the Great Plains and his alleged service as a deputy for Wild Bill Hickok in Abilene, Kansas. “In almost every work that in any way relates to southern Arizona in the 1880s, Leslie is present. This book will be the new standard for anyone interested in the life of Buckskin Frank. Both in form and content this book finally gives Frank Leslie a place in the Tombstone story.” —Gary Roberts, author of Doc Holliday: The Life and Legend

Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America

Description: The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide, concluding that the potential for increased disparities as the aging population grows is very real and rural residents remain vulnerable to a poor(er) aging experience. Recommendations for policy and practice, as well as additional research, are made to address the conclusion.

Accurate Joint Detection from Depth Videos towards Pose Analysis

Description: Joint detection is vital for characterizing human pose and serves as a foundation for a wide range of computer vision applications such as physical training, health care, entertainment. This dissertation proposed two methods to detect joints in the human body for pose analysis. The first method detects joints by combining body model and automatic feature points detection together. The human body model maps the detected extreme points to the corresponding body parts of the model and detects the position of implicit joints. The dominant joints are detected after implicit joints and extreme points are located by a shortest path based methods. The main contribution of this work is a hybrid framework to detect joints on the human body to achieve robustness to different body shapes or proportions, pose variations and occlusions. Another contribution of this work is the idea of using geodesic features of the human body to build a model for guiding the human pose detection and estimation. The second proposed method detects joints by segmenting human body into parts first and then detect joints by making the detection algorithm focusing on each limb. The advantage of applying body part segmentation first is that the body segmentation method narrows down the searching area for each joint so that the joint detection method can provide more stable and accurate results.

The AEF in Print: An Anthology of American Journalism in World War I

Description: The AEF in Print is an anthology that tells the story of U.S. involvement in World War I through newspaper and magazine articles—precisely how the American public experienced the Great War. From April 1917 to November 1918, Americans followed the war in their local newspapers and popular magazines. The book’s chapters are organized chronologically: Mobilization, Arrival in Europe, Learning to Fight, American Firsts, Battles, and the Armistice. Also included are topical chapters, such as At Sea, In the Air, In the Trenches, Wounded Warriors, and Heroes. “Some of these stories are real gems. Irving Cobb’s account of the sinking of the SS Tuscania, for example, is absolutely riveting, and the same can be said of William Shepherd’s description of life aboard US Navy destroyers in the Atlantic, Floyd Gibbons’s narration of his wounding at Belleau Wood, and George Pattullo’s roll-out of the Sergeant York legend.” —Steven Trout, author of On the Battlefield of Memory: The First World War and American Remembrance. “The well-written and evocative articles bring the war to life.” —Jennifer Keene, author of Doughboys, the Great War, and the Remaking of America.

Alloy Development and High-Energy X-Ray Diffraction Studies of NiTiZr and NiTiHf High Temperature Shape Memory Alloys

Description: NiTi-based shape memory alloys (SMAs) offer a good combination of high-strength, ductility, corrosion resistance, and biocompatibility that has served them well and attracted the attention of many researchers and industries. The alloys unique thermo-mechanical ability to recover their initial shape after relatively large deformations by heating or upon unloading due to a characteristic reversible phase transformation makes them useful as damping devices, solid state actuators, couplings, etc. However, there is a need to increase the temperature of the characteristic phase transformation above 150 °C, especially in the aerospace industry where high temperatures are often seen. Prior researchers have shown that adding ternary elements (Pt, Pd, Au, Hf and Zr) to NiTi can increase transformation temperatures but most of these additions are extremely expensive, creating a need to produce cost-effective high temperature shape memory alloys (HTSMAs). Thus, the main objective of this research is to examine the relatively unstudied NiTiZr system for the ability to produce a cost effective and formable HTSMA. Transformation temperatures, precipitation paths, processability, and high-temperature oxidation are examined, specifically using high energy X-ray Diffraction (XRD) measurements, in NiTi-20 at.% Zr. This is followed by an in situ XRD study of the phase growth kinetics of the favorable H-phase nano precipitates, formed in NiTiHf and NiTiZr HTSMAs, based on prior thermo-mechanical processing in a commercial NiTi-15 at.% Hf HTSMA to examine the final processing methods and aging characteristics. Through this research, knowledge of the precipitation paths in NiTiZr and NiTiHf HTSMAs is extended and methods for characterization of phases and strains using high energy XRD are elucidated for future work in the field.

Animal Rights and Human Responsibilities: Towards a Relational Capabilities Approach in Animal Ethics

Description: In this thesis, I analyze some of the most important contributions concerning the inclusion of animals in the moral and political sphere. Moving from these positions, I suggest that a meaningful consideration of animals' sentience demands a profound, radical political theory which considers animals as moral patients endowed with specific capabilities whose actualization needs to be allowed and/or promoted. Such theory would take human-animal different types of relationships into account to decide what kind of ethical and political responsibilities humans have towards animals. It would be also based on the assumption that animals' sentience is the necessary and sufficient feature for assigning moral status. I start from the consideration that in the history of political philosophy, most theorists have excluded animals from the realm of justice. I then propose an examination of utilitarianism, capabilities approach, and relational-based theories of animal rights (in particular the works by Kymlicka and Donaldson, and Clare Palmer) and borrow essential elements from each of these approaches to build my theory. I claim that a political theory which attaches high importance to individual capabilities, as well as to the various types of relationships we have with animals, is the most appropriate to tackle the puzzle of human responsibilities to animals.

Application-Specific Things Architectures for IoT-Based Smart Healthcare Solutions

Description: Human body is a complex system organized at different levels such as cells, tissues and organs, which contributes to 11 important organ systems. The functional efficiency of this complex system is evaluated as health. Traditional healthcare is unable to accommodate everyone's need due to the ever-increasing population and medical costs. With advancements in technology and medical research, traditional healthcare applications are shaping into smart healthcare solutions. Smart healthcare helps in continuously monitoring our body parameters, which helps in keeping people health-aware. It provides the ability for remote assistance, which helps in utilizing the available resources to maximum potential. The backbone of smart healthcare solutions is Internet of Things (IoT) which increases the computing capacity of the real-world components by using cloud-based solutions. The basic elements of these IoT based smart healthcare solutions are called "things." Things are simple sensors or actuators, which have the capacity to wirelessly connect with each other and to the internet. The research for this dissertation aims in developing architectures for these things, focusing on IoT-based smart healthcare solutions. The core for this dissertation is to contribute to the research in smart healthcare by identifying applications which can be monitored remotely. For this, application-specific thing architectures were proposed based on monitoring a specific body parameter; monitoring physical health for family and friends; and optimizing the power budget of IoT body sensor network using human body communications. The experimental results show promising scope towards improving the quality of life, through needle-less and cost-effective smart healthcare solutions.

The Art and Science of Data Analysis

Description: This thesis aims to utilize data analysis and predictive modeling techniques and apply them in different domains for gaining insights. The topics were chosen keeping the same in mind. Analysis of customer interests is a crucial factor in present marketing trends and hence we worked on twitter data which is a significant part of digital marketing. Neuroscience, especially psychological behavior, is an important research area. We chose eye tracking data based on which we differentiated human concentration while watching controllable (video game) videos and uncontrollable (sports) videos. Currently, cities are using data analysis for becoming smart cities. We worked on the City of Lewisville emergency services data and predicted the vehicle-accident-prone areas for development of precautionary measures in those areas.

Artificially Structured Boundary for Control and Confinement of Beams and Plasmas

Description: An artificially structured boundary (ASB) produces a short-range, static electromagnetic field that can reflect charged particles. In the work presented, an ASB is considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. When used to create an enclosed volume, an ASB may confine a non-neutral plasma that is effectively free of applied electromagnetic fields, provided the spatial period of the ASB-applied field is much smaller than any one dimension of the confinement volume. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space-charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible. A classical trajectory Monte Carlo (CTMC) simulation suite has been developed in C++ to efficiently simulate charged particle interactions with user defined electromagnetic fields. The code has been used to explore several ASB configurations, and a concept for a cylindrically symmetric ASB trap that employs a picket-fence magnetic field has been developed. Particle-in-cell (PIC) modeling has been utilized to investigate the confinement of non-neutral and partially neutralized positron plasmas in the trap.

Association of College and Career Readiness Indicators on Hispanic College Enrollment and Postsecondary Resiliency

Description: This investigation was a post-hoc, quantitative analysis of secondary academic performance and participation choices of Hispanic students. Three years of longitudinal student-level data was collected to examine the likelihood of college enrollment based on college and career readiness (CCR) factors. At the time of the study, CCR was defined as qualifying exam scores, credit for at least two advanced/dual enrollment courses, or enrollment in a career and technology education (CTE) coherent sequence of courses. Research participants (N = 803) consisted solely of Hispanic high school graduates from the 2014 cohort. Frequency statistics indicate 45.5% (n = 365) attended an institute of higher education (IHE) within 2 years of high school graduation. Findings reveal Hispanic females were more likely than Hispanic males to meet CCR indicators as well as postsecondary resiliency outcomes. Analysis of chi-square tests of independence suggests a moderately strong association exists between CCR indicators and postsecondary participation among high school graduates. Differences were found in terms of gender and postsecondary enrollment, x^2(6) = 24.538, p < .001. Differences were also found in terms of type of IHE and postsecondary resiliency, x^2(3) = 34.373, p < .001. More Hispanic CCR graduates enrolled at 2-year and 4-year IHE than expected by chance. While non-CCR graduates enrolled in IHE, they were less likely to meet postsecondary resiliency outcomes. CCR graduates who initially enrolled at 2-year IHE were also less likely to persist. Furthermore, the greatest contribution to differences in resiliency existed for Hispanic CCR graduates who enroll at 4-year IHE.
