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 …

Although the recent annual growth rate in the US paramedic field has been 4%, Latino and African American men have been significantly underrepresented in the field compared to their proportion in the US population at large. This problem threatens both the quality and quantity of available emergency health care. The purpose of this study was to describe how men of color (MOC) in community college paramedical programs experienced their awareness, interest, and proactive choice of paramedicine as a course of study. Using a qualitative phenomenological approach and social cognitive career theory as a theoretical framework, I interviewed 23 MOC enrolled during one semester across three community college paramedical programs in the southwestern US: 9 Latino and 14 African American, aged 18-29 with mean age 22 years. The focus of the interviews was the participants' lived experiences at various career points, as well as the enablers and disablers they had encountered. I identified three primary themes for possible use in enhancing recruitment of MOC to the paramedic field: strategic use of new digital media, promotion of the vocation's quasi-familial characteristics, and augmentation of neighborhood-based outreach. Identified areas for further research included recruitment dynamics of female paramedics, MOC persistence issues, and MOC …

For decades, urban public schools have been plagued by systemic and structural challenges that continue today. Scholars, policymakers, and the general public have pointed to problems of learning in urban schools and to low expectations for urban students' learning, but little attention has been given to how urban students themselves conceptualize learning. This study sought to fill the void by asking a group of urban students about their views of learning. A phenomenographic approach was employed to examine the qualitatively different ways in which 20 urban elementary fifth-grade students expressed their conceptions of learning and of their learning approaches. Consistent with phenomenography, the study was intended to understand the collective expressions of individuals' conceptions regarding a phenomenon, and emphasis was on the mapping of variation across the conceptions. Semi-structured interviews with open-ended questions, conducted individually, elicited the students' conceptions of the meaning of learning and their learning approaches. In a "search for meaning" approach, analyses were based on students' transcribed responses forming a pool of quotations. These quotations were divided first into "what" and "how" categories—"what" is learning and "how" does learning occur—and then into subcategories. The results were a set of categories organized in a two-level hierarchy. The three …

The recent breakthroughs in the research of brain trauma as it relates to athletics has revealed never before seen damage linked with football participation. Known as chronic traumatic encephalopathy (CTE), it is caused by activities inherent to the sport of football. School sponsored football has been granted immunity through case law and legislation in Texas. Recent research however indicates a different type of injury than those that school districts have been protected of liability from. This will provide a challenge to the immunity school districts have enjoyed regarding football. One route to abrogation of immunity is the state created danger provision established by the Supreme Court. The Fifth Circuit Court whose jurisdiction includes Texas has yet to officially adopt the state created danger theory. This research examined legal precedent to determine the challenge CTE may present the various layers of immunity surrounding school sponsored football in Texas.

It follows an organization that is willing to open up and welcome them into the community.

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.

A three-district case study was conducted to determine the effects of the 50-cent debt test on fast-growth Texas school districts. The 50-cent debt test for Texas schools came into existence as part of Senate Bill 351 in 1991. Prior to the passing of Senate Bill 351, districts in Texas were limited to issuing 10% of their assessed valuation. Of the 75 school districts that currently meet the criteria to be considered a fast-growth district, 15 of the districts had an Interest and Sinking tax rate of $0.50 in 2014. Also, 33 of the 75 districts had an Interest and Sinking tax rate of $0.40 or higher in 2014. The 50-cent cap on the interest and sinking fund tax rate for districts is arbitrary and inefficient. The limit does not take into account a district's enrollment growth or the wishes of local taxpayers who might vote to authorize debt to build additional facilities or a higher tax rate to pay down debt sooner. Over the past 20 years, Texas voters have approved $96.7 billion of the $118.4 billion resulting in over 81% of funding sought for facilities being approved. The issuance of the approved bond authorization by these voters is governed …

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 …

Gender and sexual minorities (GSM) experience considerably worse health outcomes than heterosexual and cisgender people, yet no comprehensive understanding of GSM health exists due to a dearth of research. GSM leaders in Dallas expressed need for a community needs assessment of GSM health. In response to this call, the Center for Psychosocial Health Research conducted a needs assessment of gender and sexual minority health in Dallas (35 interviews, 6 focus groups). Competency was one area highlighted and shared across existing research. Thus, the current study explored how competency impacts gender and sexual minorities' experience of health care in Dallas. We utilized a consensual qualitative research approach to analyze competency-related contents. The meaning and implications of emerging core ideas were explored. These findings were also used to develop a survey instrument.

The purpose of this study was to explore characteristics that influence Latino male students' enrollment in four-year colleges. This study utilized a mixed-methods approach and acquired information specifically pertaining to the high school Latino male population. Participants for the study included Latino male high school students in Grades 9-12, parents of Latino male high school students in Grades 9-12, and counselors of high school students in Grades 9-12. The study was conducted across two campuses. Data for student and parent participants were obtained through an online survey questionnaire and counselor data was obtained through face-to-face semi-structured interviews. The results of this study reveal that there are influential characteristics that contribute to Latino males' potential enrollment in college. Of the data obtained from student participants, 70.2% of participants on Campus 1 and 90.5% of participants on Campus 2 planned on attending college. Responses from parent surveys found that 85.8% of parents had expectations for their Latino male student to attend college. Through the semi-structured focus group interviews, it was found that the school district and campuses in which the study was conducted had several procedures or processes in place to positively encourage Latino male student enrollment in four-year colleges. Results of …

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 …

The Texas Stream Team (TST) is one of an increasing number of citizen science water monitoring programs throughout the US which have been continuously collecting surface water quality data under quality assurance protocols for decades. Volunteer monitoring efforts have generated monitoring datasets that are long-term, continuous, and cover a large geographic area - characteristics shown to be valuable for scientists and professional agencies. However, citizen science data has been of limited use to researchers due to concerns about the accuracy of data collected by volunteers, and the decades of water quality monitoring data collected by TST volunteers is not widely used, if at all. A growing body of studies have attempted to address accuracy concerns by comparing volunteer data to professional data, but this has rarely been done with large-scale, existing datasets like those collected by TST. This study assesses the accuracy of the volunteer water quality data collected across the state of Texas by the TST citizen science program between 1992-2017 by comparing it to professional data from corresponding stations during the same time period, as well as comparing existing and experimental data from a local TST partner agency. The results indicate that even large-scale, existing volunteer and professional …

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.

The purpose of this research was to investigate the relationships between job satisfaction, work engagement, and turnover intention of health science teachers in the state of Texas. The healthcare profession is one of the largest growing occupations in the U.S. nationwide. The job growth outlook for healthcare professionals is projected to be on average 34% between 2014 and 2024. Despite the growing healthcare job categories, there is a shortage of healthcare professionals in the U.S. This study addressed the shortage of health science teachers in secondary education. Considering the importance of healthcare, especially with an aging U.S. population, it is critical to study the impact of work engagement and job satisfaction on teacher intent to leave the health science teaching profession. Through a correlational survey research design it was found that job satisfaction and work engagement are negatively related to turnover intention. Hierarchical regression analysis indicated that job satisfaction accounted for 39.6% of the variation in turnover intention. Findings also showed that work engagement did not moderate the relationship between job satisfaction and turnover intention. Implications for research and practice are discussed and conclusions are provided.

Leaders of the 84th Texas Legislature drafted and ratified HB 1164 (2015), prompting the Texas Education Agency to pilot a portfolio assessment option for assessing student writing growth and proficiency. The purpose of this study was to identify the perceptions, characterize the experiences, and identify the forces that influenced initial implementation of the statewide writing pilot. Through interviews with district leaders and the collection of open-ended questionnaires from participating educators, a collective case study method was conducted and allowed for analysis of cross-case themes. The identification of restraining and driving forces affecting implementation of the statewide pilot program provided insight into considerations for next steps in the evaluation of student writing achievement and growth. Three primary perceptions emerged as restraining forces influencing implementation: influences of inadequate funding, inconsistencies of implementation, and navigation of multiple assessment systems. Six primary themes related to driving forces influencing implementation were identified: using sociocultural and authentic methods, engaging in reflective practices, increasing volume and variety of writing opportunities, assessing student growth, aligning methods of instruction and assessment, and reducing stress for students. Effective professional development, dependent upon funding and staffing allocations; two-way channels of communication for participant reflection and feedback; and effective assessment structures must …

Makerspaces are a popular, new concept being implemented in public, academic, and school libraries, and as stand-alone spaces. The literature reflects the newness of the topic with a limited number of articles and studies and even less about the users of makerspaces themselves. This study explored information sharing behaviors in the Dallas Makerspace as an informal learning environment and described their preferred method of information transfer from one member to another. It employed a mixed methods methodology using surveys, interviews and observations. The study identified how the rules and policies in place at the makerspace influence the information seeking process and how the Dallas Makerspace exchanges information effectively. Dallas Makerspace is one of the largest non-profit work groups in its size, and this research study answers how information is exchanged in an informal environment.

Using a phenomenological approach, this qualitative study examined the perspectives of Latino parents and their involvement in the decision of their child to enroll in an advanced mathematics course in sixth grade. Since enrollment in Algebra I in high school is said to be a strong predictor of college attainment and with the growing number of Latino students across the nation, this study has the potential to help district and campus leaders establish whole-school systems for communicating with Latino parents to encourage their children to enroll in advanced mathematics courses at earlier grades. Participants in this study included four sixth-grade students enrolled in an advanced mathematics course, four enrolled in regular mathematics, their mother or father, two mathematics teachers, a school counselor, and two district administrators. Data analyzed included audio recordings of semi-structured interviews of each of the participants. The findings suggested that the district has proactively developed a systematic process of creating that includes six data points to create a student profile of students that will do well in advanced mathematics. This process is helping the district close the gap between total Latino school enrollment and the enrollment of Latino students in advanced mathematics. The findings also suggested that …

The anthropogenic alteration of riverine ecosystems has led to declines in the abundance and diversity of freshwater mussels (Bivalvia: Unionoida) worldwide. Central Texas is home to a diverse freshwater mussel fauna including three candidates for federal listing under the Endangered Species Act. Surveys conducted over the last few decades suggest many of the endemic freshwater mussel species in Texas exist in small isolated populations that may be vulnerable to the deleterious effects of genetic diversity loss. Microsatellite primers from two closely related species were used to identify a set of genetic markers that functioned in the Golden Orb (Quadrula aurea). Microsatellite markers were then applied to document the population genetic structure of Q. aurea within and among three connected river drainages in southeastern Texas. Gene flow within existing Q. aurea populations appears high indicating little potential for genetic issues stemming from isolation and inbreeding. Two weakly divergent admixed populations were identified occupying the San Antonio and Guadalupe/San Marcos rivers. Population genetic structure was related to river basin affiliation, but results for environmental factors were unresolved. Current effective population size estimates are large for the Guadalupe/San Marcos drainage and moderately large for the San Antonio drainage and there is no clear …

This study investigated the presence of technology leadership components in Texas principal preparation programs. Programmatic and course information of principal preparation programs holding accreditation with Texas Education Agency were analyzed to determine presence of technology leadership instruction. Results were compared with Shrum et al.'s 2011 research, and showed a slight increase in presence. This study also examined possible differences in technology leadership components based on if the course was delivered online, face-to-face, or blended. Results showed a stronger presence of technology leadership in online courses. Additionally, the degree of alignment of technology leadership components being taught in principal preparation programs in Texas with the International Society for Technology in Education was explored. Results showed a positive correlation between technology leadership components instruction with the International Society for Technology in Education.

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.

The exponential growth in medical pharmaceuticals and related clinical trials have created a need to better understand the decision-making factors in the processes for developing hospital medication formularies. The purpose of the study was to identify, rank, and compare major factors impacting hospital formulary decision-making among three prescriber groups serving on a hospital's pharmacy and therapeutics (P&T) committee. Prescribers were selected from the University of Texas, MD Anderson Cancer Center which is a large, multi-facility, academic oncology hospital. Specifically, the prescriber groups studied were comprised of physicians, midlevel providers, and pharmacists. A self-administered online survey was disseminated to participants. Seven major hospital formulary decision-making factors were identified in the scientific literature. Study participants were asked to respond to questions about each of the hospital formulary decision-making factors and to rank the various formulary decision-making factors from the factor deemed most important to the factor deemed least important. There are five major conclusions drawn from the study including three similarities and two significant differences among the prescriber groups and factors. Similarities include: (1) the factor "pharmacy staff's evaluation of medical evidence including formulary recommendations" was ranked highest for all three prescriber groups; (2) "evaluation of medications by expert physicians" was ranked …
