This study applies an empirical research method determine whether Texas public school principals’ leadership styles, coupled with their use of real time data in a data warehouse, influenced their leadership ability as measured by student achievement. In today’s world of data rich environments that require campuses and districts to make data-driven decisions, principals find themselves having to organize and categorize data to help their school boards, campuses, and citizenry make informed decisions. Most school principals in Texas have access to data in multiple forms including national and state resources and a multitude of other data reports. A random sample of principals was selected to take the Multi Factor Leadership Questionnaire (MLQ5x) and the Principals Data Use Survey. The MLQ5x measured principals’ leadership styles as transformational, transactional, or passive avoidant. The Principals Data Use Survey measured how principals use data to inform campus decisions on student achievement, shaping the vision of the campus, and designing professional development. Data obtained from the survey were correlated to determine the relationship between principals’ use of data warehouses and their leadership styles on student achievement as measured by the Texas Assessment of Knowledge and Skills. The results yielded significant relationships between student achievement, principals’ leadership …

The purpose of the study was to answer the questions: Do students show greater academic success in English language arts/reading as measured by the Texas Assessment of Knowledge and Skills (TAKS) exam scores in secondary education when their teachers are the same ethinicity? Do students show greater academic success in math as measured by the TAKS exam scores in secondary education when their teachers are the same ethnicity? Minority students' success on the TAKS test was compared to the assessment scores of White students from the 2010-2011, 2011-2012, and 2012-13 school year in thre suburban school districts. This topic has been a subject of discussion since the late 10970s when Cardenas and Cardenas (1977) studied the achievement among minority students and their White peers. The conversation continued through authors such as Takei and Shouse (2008), Hays (2011), Ladson-Billings (2006), Dee (2003, 2005), and Brown (2006). To answer these research questions, a hierarchical multiple regression analysis was conducted on the data collected. Although the study verified the achievement gap between minority students and White students, the study indicated no consistent pattern corroborating that minority students were more successful when taught by teachers of the same ethnicity. In many cases, students learned …

Energy and the natural environment are central concerns among stakeholders across the globe. Decisions on this scale often require interaction among a myriad of institutions and individuals who navigate a complex variety of challenges. In Denton, Texas in 2014, voters were asked to make such a decision when tasked with a referendum to determine whether the city would continue to allow hydraulic fracturing activity within its borders. For social scientists, this situation requires further analysis in an effort to better understand how and why individuals make the decisions they do. One possible approach for exploring this process is a method of poststructuralist critical rhetorical analysis, which is concerned with how individuals’ identities change through interaction with institutions. This study reflects upon the texts themselves through a poststructuralist critical rhetorical analysis of images employed by those in favor of and those against Denton’s ban on hydraulic fracturing in an attempt to identify images that alter the grid of intelligibility for the audience. The paper includes deliberation about the relative merits, subsequent disadvantages, and possible questions for further study as they relate to the theoretical implications of critical rhetorical analysis as information science. Ultimately, the study identifies poststructuralist critical rhetorical analysis as …

Lisa Markley, a.k.a. "Miz Markley", is a genuinely happy person even if she is not particularly financially successful as a musician. In an effort to validate my own choices as an artist, I chose to follow her. What was intended to be a portrait of a working musician, becomes instead a feminist musical essay film about the transformative power of art making.

This study provides a qualitative look at Texas' Professional Service Providers' (PSPs) strategies for supporting low-performing schools. Four PSPs were selected for participation based on the number of schools they helped exit the Texas Title I School Improvement Program from 2007-2012. Data collected and analyzed included provider and principal interviews, providers' progress reports documenting services, and principals' evaluations of provider services. Results indicated key support strategies in two of four cases were supporting and mentoring/coaching while communicating and building trust were important in the other two cases. Communicating, reviewing information, and planning were important across all cases. The quality indicators aligning with the PSPs' strategies were fit, comprehensiveness, and coherence. They were also the most common across all cases. Finally, analysis of the evaluation of provider services revealed PSP-1 with the highest ratings, followed by PSP-2, PSP-3, and PSP-4 respectively. The findings suggest, first, that PSP support has a dual nature. Contextual support was provided based on the campus leaderships' skills and requests. PSPs also ensured coherence among the strategies of all stakeholders. Secondly, a hierarchy of quality service indicators aligned to the PSPs' strategies: fit, comprehensiveness, and coherence. Finally relationships are vital to a successful provider-campus relationship. The findings …

Bumble bees (Bombus spp.) are adept pollinators of countless cultivated and wild flowering plants, but many species have experienced declines in recent decades. Though urban sprawl has been implicated as a driving force of such losses, urban green spaces hold the potential to serve as habitat islands for bumble bees. As human populations continue to grow and metropolitan areas become larger, the survival of many bumble bee species will hinge on the identification and implementation of appropriate conservation measures at regional and finer scales. North Texas is home to some the fastest-growing urban areas in the country, including Denton County, as well as at least two declining bumble bee species (B. pensylvanicus and B. fraternus). Using a combination of field , molevular DNA and GIS methods I evaluated the persistence of historic bumble bee species in Denton County, and investigated the genetic structure and connectivity of the populations in these spaces. Field sampling resulted in the discovery of both B. pensylvanicus and B. fraternus in Denton County's urban green spaces. While the relative abundance of B. fraternus in these spaces was significantly lower than historic levels gleaned from museum recors, that of B. pensylvanicus was significantly higher. Statistical analyses found …

In North Texas, the Barnett Shale underlies large areas of the Dallas-Fort Worth Metroplex (DFW), which magnifies debates about the externalities of shale gas development (SGD). Continued demand for natural gas and expansive urbanization in DFW will cause more people to come in contact with drilling rigs, gas transport, and other urban shale gas landscapes. Thousands of gas wells within the DFW region occupy a large, yet scattered land surface area. DFW city planners, elected officials, and other stakeholders must deal with current and future urban growth and the surface impacts that are associated with gas development. This research examines how shale gas landscapes affect urban land uses, landscapes, and patterns of development in DFW. The study focuses on multiple fast growing DFW municipalities that also have high numbers of gas well pad sites. This study asks what are the spatial characteristics of gas well production sites in DFW and how do these sites vary across the region; how do gas well production sites affect urban growth and development; and how are city governments and surface developers responding to gas well production sites, and what are the dominant themes of contestation arising around gas well production sites and suburban growth?

School leaders often contemplate implementing measures that will increase community and parent involvement in schools. There is a shortage of research that concisely takes school leadership through a process that details how to integrate parent and community input in a school transformation initiative and careful analysis of student outcomes. Within this study, I provide an in-depth look at one school district’s efforts to engage its community through strategic planning and mission and vision redesign. This process includes community involvement at every phase. For the purpose of this study, community refers to both community members who do not have children in the school system and parents of current students. In this study, I outline the inception of the transformation effort, the ongoing efforts to include community input in decision-making and campus implementation, and finally a review of the overarching impact on leadership, staff, students and community. Data collection analyzed in this study include assessment data, survey data, discipline data and walk through data collected by the school district.

The purpose of this study was to provide a snapshot of current Human Resources (HR) and Management curricula of four-year public universities in Texas in 2016 and evaluate their alignment with the competencies of the SHRM Competency Model®. This study used a mixed methods approach and analyzed course syllabi for a purposeful sample of 21 public universities in Texas. The course objectives referenced explicitly and/or implicitly all nine competencies. Three courses encompassed all nine competencies, and 84% of all programs demonstrated alignment with the competencies. “Business Acumen”, “Critical Evaluation”, “Communication” and “Relationship Management” were the most frequently referenced competencies in course syllabi. “Consultation” appeared the least frequently. This comprehensive analysis revealed that there is alignment between course curricula of public universities in Texas and competency expectations of graduates wishing to pursue a career in Human Resources. Recommendations applied to four areas including scholarship, university administration, professional associations, and practitioners.

Conventional sources of emissions have been a prime target for policymakers in designing pollution control strategies. However, the evolution of shale gas activities is a growing concern over the impact of unconventional sources on urban and regional air quality. Owing to the development of Barnett Shale production, the fast-growing Dallas-Fort Worth (DFW) metroplex has encountered both types of these emissions. Oil and gas activities result in emissions of ozone precursors, notably volatile organic compounds (VOC). The major objective of this study was to evaluate the spatio-temporal distribution of VOC in order to highlight the influence of unconventional emissions. The study utilized measurements from automated gas chromatography (AutoGC) monitors to analyze the patterns of the total non-methane organic compounds (TNMOC) and relative contributions from marker species of traffic versus oil and gas activities. In this study, data from 2001-2014 was obtained from the Texas Commission on Environmental Quality (TCEQ) for fifteen monitoring sites within the North Texas region. With over a thousand wells in a 10 mile radius, two of the rural sites measured twice as much TNMOC as compared to the urban site in Dallas. Source apportionment analysis was conducted using Positive Matrix Factorization (PMF) technique. The target site located …

Today breastfeeding is a common conversation with the ever-growing holistic movement and the effort to 'go green' as demonstrated by the proliferation of the organic food industry in recent years within the United States. Breastfeeding may reduce poor health outcomes including infant morbidity and mortality. Infant mortality is a priority in Tarrant County within southeast Fort Worth as defined by this project’s client Healthy Moms – Healthy Babies – Healthy Community. The purpose of this research was to identify the contextual factors that influence breastfeeding decisions among the zip codes in southeast Fort Worth in which infant mortality is greatest. In analysis of the data among breastfeeding mothers and stakeholders, support was the greatest contribution to successful breastfeeding.

The effect of shale gas activities on ground-level ozone pollution in the Dallas-Fort Worth area is studied in detail here. Ozone is a highly reactive species with harmful effects on human and environment. Shale gas development, or fracking, involves activities such as hydraulic fracturing, drilling, fluid mixing, and trucks idling that are sources of nitrogen oxides (NOX) and volatile organic compounds (VOC), two of the most important precursors of ozone. In this study two independent approaches have been applied in evaluating the influences on ozone concentrations. In the first approach, the influence of meteorology were removed from ozone time series through the application of Kolmogorov-Zurbenko low-pass filter, logarithmic transformation, and subsequent multi-linear regression. Ozone measurement data were acquired from Texas Commission on Environmental Quality (TCEQ) monitoring stations for 14 years. The comparison between ozone trends in non-shale gas region and shale gas region shows increasing ozone trends at the monitoring stations in close proximity to the Barnett Shale activities. In the second approach, the CAMx photochemical model was used to assess the sensitivity of ozone to the NOX and VOC sources associated with shale oil and gas activities. Brute force method was applied on Barnett Shale and Haynesville Shale emission …

Community college students transfer to public universities experiencing a pathway filled with complexity and inequity. Transfer students are not able to graduate at the same pace as native students at the university and complete their baccalaureate degrees 18% below the rate of native students. Policymakers have attempted to address the baccalaureate gap. This qualitative study explored the perspectives of Texas policymakers and policy influencers on the efficacy of policies intended to improve transfer outcomes. This study investigated what experience participants have with transfer policy, what their perceptions of the transfer pathway are, and how their voices can refine an understanding of policy development and ways to improve student persistence. Purposeful sampling was used to explore the perspectives of 14 Texas policymakers and those that influence policy. Findings revealed that significant gaps exist between expectations and student realities and that the completion agenda is driving policy decisions. Participants perceived that transfer students have been ignored in the completion metrics, which influence institutional priorities. Moreover, the decentralized system of independent, autonomous institutions is a major contributor to inefficiencies such as excessive student credit hours. Improving the transferability of courses was a priority recommendation of all participants both because it benefits the State’s …

The purpose of the study was to examine district, campus, and community determinants of principal’s salaries using a spatial econometric framework. Among the district variables business tax (p = 0.001), property tax (p < .01), and the Herfindahl Index (measure of competition) were statistically significant indicators of principal salaries. The results suggest that more affluent districts tend to pay principals higher salaries, which was expected. Regarding campus characteristics, the percent of economically disadvantaged was not a statistically sound indicator (p = 0.468), but campus enrollment was significant (p = <.01). Interestingly as the percentage of economically disadvantaged students increased, the principal salary decreased. In contrast, as student enrollment increases the salary of principals increases, suggesting that principals of larger campuses earn higher salaries. Interestingly, student achievement was not a statistically significant predictor of principals’ salary given that pay for performance in Texas is at the forefront of political debate. Among the variables examined at the community level, only the percentage of homes owner occupied (p = 0.002) was found to be a statistically significant indicator of principal salary (p = .002). The lack of evidence on reforms, such as determinants of principal salary, points to data and research deficiencies to …

This study uses the storm surge sediment beds deposited by Hurricanes Audrey (1957), Carla (1961), Rita (2005) and Ike (2008) to investigate spatial and temporal changes in sedimentation rates on the McFaddin National Wildlife Refuge in Southeast Texas. Fourteen sediment cores were collected along a transect extending from 90 to 1230 meters inland from the Gulf Coast. Storm-surge-deposited sediment beds were identified by texture, organic content, carbonate content, the presence of marine microfossils, and Cesium-137 dating. The hurricane-derived sediment beds are marker horizons that facilitate assessment of marsh sedimentation rates from nearshore to inland locations as well as over decadal to annual timescales. Near the shore, on a Hurricane Ike washover fan, where hurricane-derived sedimentation has increased elevation by up to 0.68 m since 2005, there was no measurable marsh sedimentation in the period 2008-2014. Farther inland, at lower elevations, sedimentation for the period 2008-2014 averaged 0.36 cm per year. The reduction in sedimentation in the period 2008-2014 on the nearshore part of the marsh is likely due to reduced flooding in response to increased elevation from hurricane storm surge sediment deposition. These results provide valuable knowledge about the sedimentary response of coastal marshes subject to storm surge deposition and …

Representatives of the City of Highland Village expressed concern over the risk of wildfires for their community. Anthropology provides many tools for and examples of disaster assessment of preparedness, response, recovery, and mitigation. These tools combined with Geographic Information Systems (GIS) can provide a holistic, cultural ecological look at how such a disaster may take place in the city. The project's methods included a detailed survey of preparedness steps which was analyzed using SPSS and also imported into ArcGIS for spatial analysis, and semi-formal, in-depth interviews with residents of the community regarding preparedness, response, and recovery. Residents fell into a middle category of preparedness, with the majority of participants considering or implementing a few recommended preparedness steps. Interview participants expressed respect for and trust of the city and first-responders, as well as a willingness to volunteer their help during response and recovery stages. Finally the American Community Survey showed that resident socioeconomic vulnerability was considerably low, and no action needed to be taken to advocate for at-risk individuals. Overall, the City of Highland Village showed a high resiliency to disaster. A wildfire likely will not have a major impact on the community as a whole, though the city may reduce …

Heat pumps are a vital part of each building for their role in keeping the space conditioned for the occupant. This study focuses on developing a model for the ground-source heat pump at the Zero Energy lab at the University of North Texas, and finding the minimum data required for generating the model. The literature includes many models with different approaches to determine the performance of the heat pump. Each method has its pros and cons. In this research the equation-fit method was used to generate a model based on the data collected from the field. Two experiments were conducted for the cooling mode: the first one at the beginning of the season and the second one at the peak of the season to cover all the operation conditions. The same procedure was followed for the heating mode. The models generated based on the collected data were validated against the experiment data. The error of the models was within ±10%. The study showed that the error could be reduced by 20% to 42% when using the field data to generate the model instead of the manufacturer’s catalog data. Also it was found that the minimum period to generate the cooling …

This qualitative case study explored how school district and campus-level administrators coordinate resources and services for currently enrolled homeless students. Participants in this study included three district-level administrators designated as the homeless liaison and three campus principals. Data collected and analyzed included audio recordings of semi-structured interviews of each participant, documents at the district and campus-levels, school board meeting notes, and research field notes. The findings suggested that district and campus stakeholders embraced a shared vision of collaborative policy implementation to support the needs of students living in homelessness conditions. Findings also suggested that moral purpose is reflected through the intentional, collaborative efforts of district and campus administrators. Additionally, the findings suggested that social capital develops in the collaborative processes between district and campus leaders while they broker resources to foster developing social capital of this student population. Mobilization of resources through collaborative policy implementation can foster cohesion while supporting students and can counter the impact of living in homelessness conditions.

The Dallas Morning News is a leader in using engagement journalism to increase and retain digital subscribers. This ethnography examined the efficacy of the engagement journalism work by the News in rebuilding trust and forming relationships with its audience. This research is exceptionally timely as more newsrooms are erecting paywalls to their content and asking their audiences to offer monetary support in exchange for greater access and engagement by journalists. This work is examined through two mass communications theories: functionalism, which says a society can be viewed like an ecosystem as a "system in balance" consisting of complex sets of interrelated activities, each of which supports the others in maintaining the system as a whole; and the dual responsibility model, which says that companies should operate in the best interests of all in the community who depend on them, not only those who benefit financially. Additionally, the work is considered from a human-interaction design standpoint to evaluate whether the News has created affordances that enable the journalists and the readers to communicate, and whether the journalists are effectively practicing service design when publishing news and information for the audience.

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 …

In this study, I explored the different perceptions of teachers in a large urban school district in Texas towards a pay-for-performance program used on their respective campuses between 2011-2016. In total, 97 teachers from four different middle school campuses participated in this study. A descriptive analyst was conducted on teacher responses to an online survey to answer the research questions examined in this study: 1) What are teachers' perceptions of the pay-for-performance program's impact on teacher motivation?, 2) What are teachers' perceptions of the pay-for-performance program's impact on teacher retention?, and 3) What are the differences among teachers' perceptions of the pay-for-performance programs on the participating campuses? The results indicate 48.3% and 53.4% of the participants perceive pay-for-performance programs as having a positive impact on teacher motivation and teacher retention, respectively. Additionally, the results demonstrate 47.5% of participating teachers responded positively towards the pay-for-performance program on their respective campuses. This study has implications for policymakers and school district leaders who may consider implementing teacher pay-for-performance programs. Future research studies might explore school districts of different sizes throughout Texas and across the United States to gain a broader prospective of pay-for-performance programs.

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.
