Exploring District and Campus Leaders' Practices that Support Homeless Students in Public Schools

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.

Evaluating the Efficacy of Engagement Journalism in Local News: An Ethnographic Study of the Dallas Morning News (open access)

Evaluating the Efficacy of Engagement Journalism in Local News: An Ethnographic Study of the Dallas Morning News

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.

The Bobwhite Population Decline: Its History, Genetic Consequences, and Studies on Techniques for Locating and Assessing Current Populations (open access)

The Bobwhite Population Decline: Its History, Genetic Consequences, and Studies on Techniques for Locating and Assessing Current Populations

The northern bobwhite (Colinus virginianus) population decline is a severe, rangewide phenomenon beginning >150 years ago and continuing today. In this investigation, I: 1. document the timeline of bobwhite population decline and unintended genetic consequences of attempted remedies, 2) develop a model useful for predicting possible locations of potentially sustainable bobwhite populations in semiarid rangeland in Texas and Oklahoma, and 3) examine the relationship between population monitoring data and meteorological factors. While breeding season call counts of male bobwhite have been used for >70 years to provide estimates of fall populations for hunting, most studies of call counts have focused on mathematics and statistical accuracy of the count, largely overlooking the influence of meteorological factors on call counts. Here, I present the results of >4,400 individual point counts and examine their relationship with meteorological variables recorded at each stop. Humidity was positively correlated with the number of birds recorded (ρ = 0.275, p < 0.001) and temperature was negatively correlated (ρ = -0.252, p < 0.001). The number of birds recorded was significantly higher in wet years than in drought years. There was no significant correlation between wind velocity and number of birds recorded. These results suggest that, while weather …

Increasing Effective Thermal Resistance of Building Envelope's Insulation Using Polyurethane Foam Incorporated with Phase Change Material (open access)

Increasing Effective Thermal Resistance of Building Envelope's Insulation Using Polyurethane Foam Incorporated with Phase Change Material

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%.

Student Perceptions of Teacher Credibility: A Predictor of Academic Success (open access)

Student Perceptions of Teacher Credibility: A Predictor of Academic Success

While the idea of source or teacher credibility dates back to the Greek philosopher, Aristotle, research to connect this perceived credibility with individual affective and cognitive growth is a more recent phenomenon. In 2009, a credibility learning model connecting perceived credibility to cognitive learning with university-aged subjects was established. In contrast, this research project focused on determining a link between K-12 students' perception of teacher credibility, as determined by a student survey, to cognitive academic achievement as rated by a standardized test, the State of Texas Assessment of Academic Readiness (STAAR). The survey data were obtained through a pre-existing campus climate survey that was created to assist campus and district administrators in determining campus needs and developing a campus improvement plan. The assessment data were obtained through the Texas Education Agency database. The data were analyzed using quantitative research methods, including traditional univariate and multivariate statistical techniques such as principal component analysis, chi-square tests for independence, and binomial logistic regression. The findings of the study revealed no link between the survey instrument used and student academic achievement on the STAAR reading and mathematics assessment. The survey used did not align with the review of literature regarding student's perception of teacher …

Identifying Community Access to Veterinary Services in Southern Dallas (open access)

Identifying Community Access to Veterinary Services in Southern Dallas

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.

Improving Instruction through Teacher Evaluation: Principal and Teacher Perceptions of Leadership Practices and Policy Tools within the Evaluation Process (open access)

Improving Instruction through Teacher Evaluation: Principal and Teacher Perceptions of Leadership Practices and Policy Tools within the Evaluation Process

In recent decades, changes to federal and state accountability policy and related teacher evaluation systems occurred in the United States with minimal input from two of the largest groups of stakeholders impacted: principals and teachers. For this case study, I explored principals' and teachers' perceptions of their experiences with the Texas Teacher Evaluation and Support System (T-TESS), specifically the role of leadership practices and use of the evaluation rubric as a policy tool within an evaluation process. The study took place at one elementary school. Teachers perceived the evaluation process as carrying out its intended purpose of improving instruction through professional growth. Principals and teachers viewed the teacher evaluation system and the teacher evaluation rubric, a policy tool designed to facilitate and inform the processes and practices used to improve instruction in their districts and schools, as effective. Important district-level decisions also impacted how principals and teachers perceived the T-TESS. District-level decisions included policy related to frequency of required observations, methods of including student performance data, decisions related whether to issue a single rating or multiple ratings, and evaluation of specialized teachers. School-based leadership behaviors and practices were also found to influence teachers' perceptions related to the effectiveness of teacher …

Horn Concerto in E-flat Major (C41) by Antonio Rosetti: A Critical Edition (open access)

Horn Concerto in E-flat Major (C41) by Antonio Rosetti: A Critical Edition

This project delivers to the scholar and performer a critical edition of a little-known horn concerto by Antonio Rosetti. Standing in contrast to performance or practical editions, critical editions demand that the editor exerts a non-trivial measure of authority over the state of the text. Performers often find this fact to be uncomfortable given the normal tendency to revere the perceived intent of the composers based upon the text that they set down. When engaging with sources, it is rarely clear what that intent is, or which of the available sources most closely represents that intent. Those available sources often disagree with one another, even those in the composer's own hand. It is vital for the editor to know, as precisely as is possible, who created the source material, when they created these sources, and why they created these sources. At that point the editor must decide which sources will best fit his or her framework for the creation of the critical edition. At that point the editor will grapple with numerous inconsistencies and ambiguities within those sources, and then use his or her own authority to fix the text of the composer's work into a single version for today's …
