Many factors have prompted the adoption of partial-market exit strategies in retail as a means of reducing cost and minimizing risk. These mass closures have become more frequent in recent years. Marketers and economists have offered explanations for these closures linked to the rise of e-commerce, the real estate cycle and general changes in consumer taste. The research here marks an attempt to apply geospatial and econometric methods to better understand what factors explain the spatial variation of these closures across the United States. Specifically, the analysis examines the store networks of Sears, J.C. Penney and Macy's- large, established department stores that, collectively, announced over 100 closures at the beginning of 2017. By treating each store as a unit of observation, and a closure as a limited dependent variable, this analysis will attempt to quantify the relationship between place-specific factors and retail closures using Probit modeling. This application of modeling marks a deviation from traditional analyses in retail geography which, up until the early 2000s, have focused almost entirely on store development and growth. The results reveal patterns of spatial clustering of closures in and around the Rust Belt and demonstrate the strong negative effect of competitive agglomeration on the …

Retail clinics are walk-in clinics designed for convenience and for servicing minor health issues and certain acute conditions. The model began as a way of bringing both convenience and care to areas that have lower levels of access to primary care resources. With the implementation of Affordable Care Act (ACA) in March 2010, populations that were previously uninsured were now required to have access to some level of health insurance. These populations presented a potential new market for retail clinics. This research shows that post implementation of the ACA, retail clinics tend to locate in areas with higher incomes and, generally, greater access to primary care.

In the first half of the twentieth century, sporadic attempts of avant-garde composers to include sounds other than pitch in musical composition paved the way for the composers in the second half to embrace the sound of all types in their creative works. The development of technology since the mid-past century has facilitated composers' inclusive use of sound. The recent achievements in electronics and computers have led to cost-effective tools for today's composers to explore new possibilities in sound design and manipulation. Gradual for tenor saxophone and fixed electronics is primarily concerned with noise. Among the infinite possibilities of noise types, metallic sounds significantly contribute to the composition. The title of the piece refers to the compositional process in which the music progressively unfolds itself from the beginning to the end. The methods and strategies used to present the content give rise to a form I call accretion, described as an organic process by which the musical materials grow. Within the process, while established materials are interacting, combining, and forming layers, new materials may be incorporated and take part in the process. Throughout the composition, the interaction between sounds with common properties guides the music toward interactive unity, while the …

Since the adoption of neoliberalism, many cities have taken to integrating nature with capital accumulation to create a sense of place. This has been closely tied to urban greening, or green "revitalization." As part of curating this desired character, city governments are working to roll out plans to restore and renew neighborhoods using their natural landscapes through methods such as reforestation, the creation of parks, and commercial development. These cities, deemed Entrepreneurial cities, are increasingly incorporating natural or green spaces into their development of character as part of their branding schemes. This research focuses on the role of nature as the site of economic development and community revitalization within Dallas, Texas. This research examines how the City of Dallas uses nature to attract capital, and how the narratives of development relate to residents' visions for development in the historically neglected Joppa neighborhood in the Trinity River Corridor. Development near Joppa could be an example of how the natural landscape is being used to not only attract developers but also to bring a different ‘class' of resident into the area. By exploring this intersection of nature and capital in Dallas, we can better understand the nuanced ways through which the neoliberalization …

This project seeks to clarify the historical significance of women in the American West between 1870 and 1930 through the education, careers, and personal lives of western women physicians. The narratives presented in the work provide alternative roles for western women aside from the stereotypical images found in popular culture and history, such as the "Bad Woman," the prostitute, and the obedient homesteading wife. This collective biography additionally demonstrates how women participated in American medical culture during the nineteenth and early twentieth centuries, emphasizing their agency as historical actors, and countering the common misconception that Victorian women were merely passive subjects of their time and place. The lives of four physicians named Ellis Reynolds Shipp, Mary Babcock Atwater, Mary Bennett Ritter, and Mary Canaga Rowland are available through memoirs, biographies, scholarly articles, newspapers, and other sources that contextualize their careers into the broader context of Western, medical, and nineteenth-century history. Through their personal and professional experiences, a greater story of female autonomy emerges in a period understood to be inherently oppressive to and unnavigable for women.

Feedback is used in a variety of contexts to train staff and to teach individuals new skills. Despite its popularity, there is no consensus on how to deliver it. Different measures have been used to evaluate the effectiveness of feedback, such as accuracy of responses and the sequencing of feedback delivery. The purpose of this study was to compare two feedback procedures and to explore new ways to measure the effectiveness of feedback. Four undergraduate students were exposed to two conditions: feedback before + skip the opportunity to respond and feedback after an incorrect answer. Results showed that the number of correct answers and teaching time were similar in both conditions. However, session duration was lower in the feedback before + skip condition when compared to the feedback after condition. Finally, reported emotions correlated with participants' correct responding. This study demonstrates that it is more beneficial and efficient to teach learners how to engage in a correct performance, rather than to correct responses.

The Society for the Prevention of Cruelty to Animals of Texas in Dallas, Texas offers an array of services and programs to residents in southern Dallas and other areas. However, interest in the state of access to veterinary care has been questioned for southern Dallas residents. In an area that faces certain compounding stressors, such as food deserts and transportation difficulties, a lack of access to veterinary care for pet owners is considered an additional possible stressor. Pet owners in southern Dallas, along with the SPCA of Texas, contemplate how to best provide medical care for local pets. In this body of work, I describe community access to veterinary services in southern Dallas. I provide a resident-centered explanation based on in-depth interviews with locals that discuss the current state of access to veterinary services while simultaneously analyzing the links between access to veterinary care, the area of southern Dallas itself, and ongoing issues with roaming and stray dogs.

Stravinsky seldom explained the intended theme of his works; however, he chose to do so with his Symphony in Three Movements. Stravinsky describes the first movement as a reflection on war films documenting scorched-earth tactics in China. He also states that the third movement is a reflection on the newsreels of goose-stepping soldiers, depicting the plot of the war in its entirety. In his descriptions, Stravinsky left out the second movement of the work. However, the movement already had a life of its own. The second movement expands a theme Stravinsky originally wrote for the movie The Song of Bernadette. The author, Franz Werfel, asked Stravinsky to compose music for the film when the two discussed the work and its central ideas. Although it did not appear in the film, Stravinsky recycled the music for the Symphony in Three Movements. In my opinion, the ideas of hope depicted in Werfel's novel are used by Stravinsky to evoke ideas of the importance of faith in the fallen world. My analysis aims to show the musical means used by Stravinsky to allow the central ideas from The Song of Bernadette to pervade the entirety of the Symphony in Three Movements.

DC to DC converters stabilize the voltage obtained from voltage sources such as solar power system, wind energy sources, wave energy sources, rectified voltage from alternators, and so forth. Hence, the need for improving its control algorithm is inevitable. Many algorithms are applied to DC to DC converters. This thesis designs fuzzy adaptive dynamic programming (Fuzzy ADP) algorithm. Also, this thesis implements both adaptive dynamic programming (ADP) and Fuzzy ADP on DC to DC converters to observe the performance of the output voltage trajectories.

Incorporating insulation material with phase change materials (PCMs) could help enhance the insulation capability for further building energy savings by reducing the HVAC loadings. During the phase change process between the solid and liquid states, heat is being absorbed or released by PCMs depending on the surrounding temperature. This research explores the benefits of a polyurethane (PU)-PCM composite insulation material through infiltrating paraffin wax as PCM into PU open cell foam. The new PU-PCM composite provides extra shielding from the exterior hot temperatures for buildings. Through this study, it was demonstrated that PU-PCM composite insulation could potentially help building energy savings through reducing the loads on the HVAC systems based on the building energy modeling using EnergyPlus. The Zero Energy Lab (ZØE) at the University of North Texas was modeled and studied in the EnergyPlus. It is a detached building with all wall facades exposed to the ambient. It was determined that the new PU-PCM insulation material could provide 14% total energy saving per year and reduce the electricity use due to cooling only by around 30%.

Using a multiple baseline across participants with a changing criterion, this study explored and evaluated the effects of the individualized contingency management package (goal-setting, education, etc.) with sedentary typical adults while focusing on the mentoring component and the use of the technology of the exercise tracker to increase and sustain physical exercise to a level that increased health-benefiting physical activity. During initial mentoring meeting prior to the start of baseline, each participant was given a Garmin Viovsmart 3® exercise tracker, educated on the basic components of the device, and connected to the dashboard through the Garmin Connect™ app on their smartphones. Once each participant's activity stabilized, participant began intervention with weekly mentoring meetings focused on immediate feedback (social reinforcement), goal-setting and education. Through the Connect™ app, experimenter gave social reinforcement on a VR3 schedule to each participant, and participants were encouraged to participate by commenting to other participants through a private group set up for this study. The results indicate that the individualized contingency management package was effective for three of four participants whom increased their total activity minutes from pre-intervention range 0-104 min of weekly activity to post-intervention range of 269-404 min weekly. The two participants that completed two- …

If mania and depression are part of the same pathological processes, one would predict that episodes of one prospectively increase the odds of episodes of the other. The aim of the present study was to test this hypothesis. For comparison purposes, their relationship was contrasted to the relationship between mania and periods of psychosis. Exploratory analyses also tested the degree to which episodes of each occur with greater frequency over time (i.e., kindling). Participants for the present study came from the Suffolk County Mental Health Project (N = 628), a study of first-admission patients with psychosis. Of these participants, 144 met diagnostic criteria for bipolar I disorder and were analyzed for the current study. Results indicated that mania in a given month predicted depression the following month, even after controlling for other symptoms. The reverse, however, was not the case. Mania and psychosis, in contrast, were found to be robust predictors of one another from month to month. Effects were not due to treatment or demographic differences. These findings provide evidence that mania and depression are weakly related. In contrast, mania and psychosis are more closely linked. Findings are consistent with suggestions that psychiatric nosology regroup mania more closely with …

Daytime cognitive performance and sleep/wake cycles are strongly interrelated, and cognitive dysfunction has been extensively investigated in relation to insomnia. However, methods and outcomes vary widely by study, making comparison difficult without more systematic evaluation. Review of the literature reveals discrepant findings for the relationship between both subjective and objective measures of cognitive performance and insomnia. The current meta-analysis included 42 studies investigating the relationship between insomnia and cognitive performance. Results confirmed the discrepant nature of previous findings and suggest that type of cognitive performance (e.g., simple attention, procedural memory, verbal functions) is important to consider when discussing the impact of insomnia. Mixed-effect meta-analysis of aggregate effect sizes suggest impairments in working memory, complex attention, and episodic memory are significantly associated with insomnia. Analysis of the grouped subjective cognitive performance effect size revealed no significant impact of insomnia. Average age and gender makeup of the sample, study quality, and type of insomnia measure (i.e., clinical or diagnostic criteria, validated scale, or single unvalidated item) did not consistently moderate findings. These results confirm the equivocal nature of the relationship between insomnia and cognitive performance. Overall, about 44% of the studies included in the analysis failed to use DSM or ICSD criteria …

The focus of the current study was to determine if SIP biases and perspective-taking serve as mediators between parental intimate partner violence (IPV), aggression, and interpersonal dominance in emerging adults' romantic relationships. We analyzed archival data comprised of self-report measures and TAT stories administered to 84 undergraduate students (women n = 62, M age = 21.73) between the ages 18 and 35. To test our hypotheses, we modified the social information processing model by incorporating perspective-taking, as measured through Interpersonal Decentering. Overall, we did not find significant association between witnessing parental IPV and Interpersonal Decentering maturity in college students. However, women's father-to-mother IPV was significantly negatively associated with Interpersonal Decentering maturity. For our mediation model, SIP aggressive responding biases were significantly associated with Interpersonal Decentering (average of story average scores) and with the presence of aggression in current romantic relationships; however, Interpersonal Decentering was not significantly predictive of aggression in current romantic relationships. Gender differences, study strengths and limitations, and future research directions are discussed.

This thesis study takes a mixed methods and black feminist approach to find out how black women are represented within the beauty advertisements of women's fashion magazines.

Improving water efficiency is and will continue to be a top concern to meet the world food production demands for a growing population. By having a clear understanding of water efficiencies, communities will be able to address these concerns from an economic standpoint and use more productive methods to grow food and limit water consumption. This study examines the water efficiencies of three irrigation methods over a single growing season in southeastern Oklahoma. Two crops, tomatoes and cucumbers, were grown using drip irrigation, a self-wicking container, and a non-circulating hydroponics barrel. Results at the end of the season showed the drip irrigation method had the highest water efficiency in terms of yield of product over water applied for both crops. The drip irrigation method also had the lowest associated set up costs and second lowest time requirements after the hydroponics method. These results were found to be consistent with other studies that compared drip irrigation to other irrigation methods and showed drip to have the highest water efficiencies.

This study focuses on dark-skinned, Black women's representation in Black sitcoms. Through a mixed-methods use of a comparative textual analysis and focus group, the content and context of episodes from A Different World and Dear White People are explored to illustrate portrayals of dark-skinned, Black women and how these portrayals affect dark-skinned, Black women's self-esteem. Its findings contribute to colorism research by exploring colorism in Black sitcoms. Because this topic is largely unexplored, this study seeks to begin a conversation about dark skinned, Black women's representation in Black sitcoms. The main objective is to ultimately improve their depictions and roles in Black sitcoms and hold Black creatives responsible for the role they play in promoting colorism and its ultimate effect on Black women's self esteem.

Six initial phage isolates with high titer lysates were obtained using Streptomyces toxytricini B-5426 as the host bacterium. These isolates were named Goby, Toma, Yosif, Yara, Deema, and Hsoos. However, upon completion of the sequencing, it was found that the Yara and Hsoos isolates were identical, as were Goby and Deema. As a result, final analysis was completed on only the four unique isolates. All of the phages mentioned above were isolated from soil samples from different locations. Also, they had different sizes of plaques, ranging from 0.3 – 0.9mm. Yosif had the largest plaque size. Yara's head diameter was 79nm with tail diameter of 94nm.

Artist Statement from the MFA Exhibition: "In my recent work, I have expanded upon the deconstruction, reconstruction, and reflection that has informed my artistic process for many years. My working method involves using remnants from previous works; they reappear in their original form or are reworked, aged destroyed, or recreated from different materials. My Process allows me to illustrate the passage of time as older work takes on new forms in a renewed context. New connections begin to surface as my paintings and accompanying objects are layered into a work about the passage of time as well as other passages; a migratory mentality know to all who live away from home."

This thesis argues that textual and historical analysis of The Carol Burnett Show reveals that the program utilized slapstick, women's comedy and feminist humor to create comedic parodies of television commercials, melodramas and women's films, and soap operas. Their television commercial parodies reflect Second Wave feminist critiques of media advertising contemporary with the program. Comparison of the work of early feminist film theorists and media critics to the program's parodies of film and soap opera reveal an interest in texts that address a female audience and that The Carol Burnett Show was making similar critiques to feminist media scholars in the years before it became a field of inquiry.
