Software as a service (SaaS) is a primary working pattern and a significant application model for next generation Internet application. Web GIS services are the new generation of the Software as a service that can provide the hosted spatial data and GIS functionalities to the practical customized applications. This study focused on developing a webGIS based application, Soil Moisture-Based Irrigation Scheduling Tool (SMIST), for predicting soil moisture in the next seven days using the soil moisture diagnostic equation (SMDE) and the upcoming seven precipitation forecasts made by the National Weather Service (NWS), and ultimately producing an accurate irrigation schedule based on the predicted soil moisture. The SMIST is expected to be capable of improving the irrigation efficiency to protect groundwater resources in the Texas High Plains and reducing the cost of energy for pumping groundwater for irrigation, as an essential public concern in this area. The SMIST comprised an integration of web-based programs, a Hydrometeorological model, GIS, and geodatabase. It integrates two main web systems, the soil moisture estimating web application for irrigation scheduling based on the soil moisture diagnostic equation (SMDE), and an agricultural field delineation webGIS application to prepare input data and the model parameters. The SMIST takes …

It is well established that national retail chains impact small, single location retail businesses in terms of revenue generation, retail structure, retail type diversity, and location. This study examines the retail structure and diversity of five retail districts in the City of Denton, Texas. The analysis focuses on one central business district (CBD), one traditional retail strip center (University Drive, also known as US HWY 380), one special retail district (Fry Street District), one traditional enclosed shopping mall and associated development (Golden Triangle Mall), and one power retail center (Denton Crossing). The empirical foundation for the investigation is a historical business database covering years 1997 to 2010, obtained from Info Group's Reference USA. This Reference USA database includes location, industry, and status (single versus chain location) information for each business. Retail diversity and evenness were measured for each of the five retail districts using the Simpson's Diversity Index and the Simpsons Measure of Evenness, leading to specification of the differences that exist in retail structure and diversity among the districts. Golden Triangle Mall and Denton Crossing were primarily chain location in composition while Fry Street District, the CBD, and University Drive were primarily single location in composition. Across all years, …

Upward Bound is a federally funded program designed to help low-income and first-generation high school students become college graduates by providing them with academic enrichment, financial aid information, and relevant educational experiences. Many Upward Bound programs throughout the country include a 6-week summer program when participants stay in residence halls on a university campus. The Upward Bound program at the University of North Texas is one such program. The goals of this research project are to understand how the residential component of the summer program affects the experience of participants in Upward Bound and the possible benefits it may have towards meeting the overall goals of the program. Participant observation during the 2016 UNT Upward Bound summer program and interviews with participants, RAs, program alumni, and organizational leaders uncovered the ways in which the residential component benefits and enriches the experience of participation in Upward Bound.

Her Name Was is an examination of the oppression of transgender people in a society that is built on the nominalization of cisgender people, those who gender matchers their sex assigned at birth, and how this oppression lends itself to violence. In the summer of 2015, the body of Shade Schuler, an African American transgender woman, was found in a field outside of Dallas, Texas. Ms. Shade is part of an alarming epidemic of escalating levels of targeted violence against the transgender community. This documentary pulls back the curtain as it captures the feelings and struggles of the transgender community as they attempt to navigate and survive in a cis dominating society.

This research investigates the bio-products/phase change material (PCM) composites for the building envelope application. Bio-products, such as wood and herb, are porous medium, which can be applied in the building envelope for thermal insulation purpose. PCM is infiltrated into the bio-product (porous medium) to form a composite material. The PCM can absorb/release large amount of latent heat of fusion from/to the building environment during the melting/solidification process. Hence, the PCM-based composite material in the building envelope can efficiently adjust the building interior temperature by utilizing the phase change process, which improves the thermal insulation, and therefore, reduces the load on the HVAC system. Paraffin wax was considered as the PCM in the current studies. The building energy savings were investigated by comparing the composite building envelope material with the conventional material in a unique Zero-Energy (ZØE) Research Lab building at University of North Texas (UNT) through building energy simulation programs (i.e., eQUEST and EnergyPlus). The exact climatic conditions of the local area (Denton, Texas) were used as the input values in the simulations. It was found that the EnergyPlus building simulation program was more suitable for the PCM based building envelope using the latent heat property. Therefore, based on the …

The U.S. citizenship application process is a legal and symbolic journey shaped by many cultural processes. This research project aims to bring to light the experiences of immigrants and citizenship applicants living in Dallas, Texas, to promote a better understanding of Dallas' increasingly diverse population. In addition, the purpose of this project is to provide insights to a specific client, the office of Dallas Welcoming Communities and Immigrant Affairs, about Dallas' lawful permanent residents who are eligible for citizenship and their reasons for pursuing citizenship status. The data for this project was collected through observation at various citizenship workshops and community events, as well as through semi-structured interviews with 14 U.S. citizenship applicants. Reasons for applying for U.S. citizenship discussed in this project include a desire for membership in U.S. society, access to better educational and economic opportunities, improved ease of travel and the desire to vote. Barriers to the citizenship process discussed in this project include the amount of time one must dedicate to the application, lack of clear knowledge about the process and the financial cost of the application. Other themes include the effects of capital on applicant's experience with the citizenship process, symbolic meanings of citizenship, transnationalism …

This thesis analyzes the training and perceptions on mental health of a particular population. Through the use of previous research and literature, a survey was generated and distributed to the population. The findings were used to generate policy implications for the specific population that was analyzed.

Coaching efficacy is largely influenced by mastery experiences such as formal education, coaching experience, and sport participation. Further examining specific experiences, such as exposure to sport psychology, may prove helpful in advancing our understanding of coaching efficacy. Thus, the purpose of this study was to explore male high school coaches' coaching experience to determine whether sport psychology education and interactions with sport psychology consultants relate to coaches' coaching efficacy. Participants, 585 males (Mage = 43.89 + 10.02), completed an online survey measuring coaching efficacy and coaching and sport psychology experience. A hierarchical regression analysis revealed that after controlling for years of coaching experience and school size, sport psychology education and interactions with sport psychology consultants were associated with higher overall coaching efficacy scores (p < .001). Additionally, analysis of covariance revealed that those with extensive sport psychology education had statistically higher coaching efficacy scores than those reporting no sport psychology education (p < .05). Knowledge of these phenomena may be relevant for sport psychology consultants, coach educators, and researchers.

Hauntology Man, a 48-minute documentary, follows former UNT Professor, Dr. Shaun Treat, as he leads a walking ghost tour of downtown Denton, Texas. As the expedition moves from storefront to storefront, each stop elicits a new tale. But, as Dr. Treat points out, the uncertainties of history are the real ghosts. That is, rather than simply presenting a "haunted history" of Denton, it's more accurate to say this movie's center resides at the precipice of a "haunting history." Not all ghost stories need spectres. Sometimes not knowing is ghost enough.

Elemental carbon (EC), a product of incomplete combustion of fossil fuels and biomass, contributes to climate warming and poor air quality. In urban areas, diesel fuel trucks are the main source of EC emissions from mobile sources. After emission, EC is deposited to receptor surfaces via two main pathways: precipitation (wet deposition) and directly as particles (dry deposition). Urban trees may play an important role in removing EC from the atmosphere by intercepting and delivering it directly to the soil. The goal of this research was to quantify the magnitude of EC retention in leaf waxes (in-wax EC) and EC fluxes to the soil via leaf litterfall in the City of Denton, Texas. Denton is a rapidly growing urban location in the Dallas-Fort Worth metropolitan area. A foliar extraction technique was used to determine EC retention in leaf waxes. Foliar samples were collected monthly, from April through July, from pairs of Quercus stellata (post oak, n=10) and Quercus virginiana (live oak, n = 10) trees. Samples were rinsed with water and chloroform in a two-step process to determine EC retained in leaf waxes. A Sunset OC/EC aerosol analyzer was utilized to analyze the EC content of extracts filtered onto quartz-fiber …

Disabled veterans with post-traumatic stress disorder (PTSD) exist in a category separate from many civilians and soldiers. Their experiences land them in a category distinctly marked as atypical. The standard protocol to manage this atypical subject position is prescription drugs- a mark of the ill. In a distorted, post-war American society, what happens when veterans with PTSD refuse to be labeled as ‘sick,' ‘different,' or even ‘disabled'? This thesis explores the actions and intricacies of a community of veterans who advocate for medical cannabis to manage associated symptoms of PTSD. This group of veterans campaigns for individuality, both in medical treatment and in personal experience. Collaboratively, their experiential evidence indicates that none can be treated in the same fashion. After a year of participant observation and field work, it becomes apparent that their work both individualizes and unifies the veterans. This thesis details their experiences and the results of their activist campaign to demarcate themselves.

Many senior citizens are surviving on minimal Social Security benefits and as a result, struggle with food security. Metrocrest Services in Farmers Branch, Texas, a suburb of Dallas, is a non-profit organization that provides several food programs to residents of the community including some programs that are specifically tailored to the needs of senior citizens. This project was to provide Metrocrest with an assessment of the food security of their senior clientele as well as other elderly residents of the Metrocrest service area and to evaluate the current senior focused programs. The project utilized qualitative research including both Metrocrest clients and residents who were not Metrocrest clients bot whose demographics were similar. The objectives were to determine the coping skills used by senior citizens in obtaining food, to assess seniors' awareness of the programs offered by Metrocrest, to discover barriers to accessing needed resources and to make recommendations of how programs could be improved or modified if needed. Through my research, I was able to present Metrocrest with a number of recommendations to improve their existing programs. I was also able to recommend some potential new programs that could be designed in conjunction with local senior centers to better serve …

Numerous studies have been conducted to determine predictors of perceptions and attitudes toward police. Less effort has been spent on determining university and college students' perceptions of campus police departments. The purpose of this thesis was to fill this gap in the literature with an added emphasis on exploring potential differences in perceptions between students involved in Greek Life organizations and students not involved in Greek Life organizations. Prior literature found that Greek Life students engage in risk-taking behaviors at higher rates than their counterparts, so it was hypothesized that Greek Life students would have higher levels of distrust in the campus police due to their increased engagement in risk-taking behaviors. The survey questionnaire measuring trust and procedural justice/legitimacy perceptions of campus police was distributed through convenience sampling to university students. Descriptive statistics, bivariate analyses, and multivariate analyses were utilized to analyze the data. The results showed that students overall had positive perceptions of campus police, that Greek Life students had more negative perceptions of the campus police than non-Greek Life students, and that students with prior interactions with the campus police were more likely to perceive the police to be less procedurally just/legitimate. Race/ethnicity was not found to be …

This study uses the predictive modeling program Sea-Levels Affecting Marshes Model (SLAMM) to evaluate sea-level rise hazards, such as erosion and inundation, on coastal archaeological sites with a vertical rise of sea level of .98 meters from 2006 to 2100. In total 177 archaeological site locations were collected and georeferenced over GIS outputs maps of wetlands, erosion presence, surface elevation, and accretion. Wetlands data can provide useful information about characteristics of the wetland classes, which make a difference in the ability for coastal archaeological sites to combat sea level rise. Additionally, the study evaluated predicted erosion of archaeological sites by presence or absence of active erosion on a cell-by-cell basis. Elevation map outputs relative to mean tide level allowed for a calculation of individual archaeological site datums to use NOAA tidal databases to identify the potential for their inundation. Accretion maps acquired from the SLAMM run determined the potential for the archaeological site locations to combat rising sea levels and potentially provide protection from wave effects. Results show that the most significant hazard predicted to affect coastal archaeological sites is inundation. Approximately 54% of the total archaeological sites are predicted to be inundated at least half the time by 2100. …

A population survey was conducted on the mosquito species recorded in Denton, Texas for the years of 2005 to 2015. Data used in this project were obtained from an ongoing, long-term surveillance program led by the City of Denton and conducted through the University of North Texas. Research focused on the population dynamics and community structure of mosquitoes collected within urban areas of Denton, Texas in relation to certain environmental variables. A total of 80,837 female mosquitoes were captured and represented 38 species found under the following genera: Aedes, Anopheles, Coquillettidia, Culex, Culiseta, Mansonia, Orthopodomyia, Psorophora, Toxorhynchites, and Uranotaenia. Culex quinquefasciatus was the most abundant species followed by Aedes vexans. Seasonal patterns of the most abundant species revealed high variability throughout the study. Container breeders were most abundant in August and those that breed in floodwaters were most abundant in the months of May and September. Samples were tested for arbovirus presence through the Texas Department of State Health Services in Austin, Texas and multiple pools tested positive for West Nile virus throughout the study. Stepwise multiple regression and Spearman's rank correlation analyses were performed to examine the relationship between the mosquito community and environmental variables. Data revealed that temperature, …

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley is an examination of the relationships created during the mid-nineteenth century between Anglo and Tejano elites in the five counties that make up the Lower Rio Grande Valley. Conducted through a quantitative lens, the five-chapter study seeks to demonstrate that, although the period between 1848 and 1870 was fraught with conflict and violence, the Anglo and Tejano elite of the Lower Rio Grande Valley came together in cooperation in order not only to survive these troubling times but to prosper. The thesis begins by identifying and analyzing the economic and political elite in the Lower Rio Grande Valley during the 1850s. A new crop of Anglo immigrants arrived with the Mexican-American War, but only a small number willing to assimilate to local Tejano culture were able to leave their mark on the Lower Valley. Chapter 4 relates the effect of the Civil War on the elite of the Lower Valley. It explores the profitable cotton trade during the war and the struggle that both Anglo and Tejano elites faced during Reconstruction. The thesis concludes with a macro-analysis of the twenty-two-year period from 1848-1870. It summarizes overall trends found …
