This research project sought to holistically understand how educators in Texas understand educational policies that impact LGBT students, their practices, and interventions in the classroom. The project looks at two policies: anti-bullying and sexual education policies, and provides evidence that they are intrinsically linked through the discourse surrounding LGBT issues in Texas schools.

Switchable adhesives using stimuli-responsive systems have many applications, including transfer printing, climbing robots, and gripping in pick and place processes. Among these adhesives, electroadhesive surface can spontaneously adjust their adhesion in response to an external electric field. However, electroadhesives usually need high voltage (e.g. kV) and the adhesion disappears upon turning off the signal. These limitations make them complicated and costly. In this research, we demonstrated a gold-coated silica microsphere (GCSM) with highly switchable and memorable adhesion triggered by a relatively small voltage (<30 V). In the experiment, a silica microsphere with a diameter of 15 μm was glued to a tipless atomic force microscope (AFM) cantilever. The nanoscale thick gold coating was sprayed on the surface of the microsphere by a sputter coater. AFM was used to explore the tunable adhesion with an external voltage at different relative humidity (RH). The results revealed that when applying a positive electrical bias at high RH, the adhesive force increased dramatically while it decreased to almost zero after applying a negative potential. Even if the bias was turned off, the adhesive force state could still be kept and erased on demand by simply applying a negative voltage. The adhesive force can be …

Although one-to-one technology programs are rapidly expanding in secondary schools, the literature about how to effectively leverage these programs to improve teaching and learning is relatively small. Little guidance is available for school leaders attempting to improve teachers' willingness and ability to incorporate technology effectively into their instruction. The purpose of this mixed-methods case study was to discovery what supports school leaders provide to promote high levels of computer self-efficacy and transformational digital pedagogies in one-to-one learning environments. Data were collected from English language arts, Social Studies, and science teachers in three high schools in a suburban school district in northeast Texas using an online survey, eight virtual semi-structured interviews, and two virtual focus group interviews. Data were analyzed using descriptive statistics and deductive and inductive analysis. The findings of the study reveal most teachers perceived their ability to effectively deliver digital instruction as strong, and most were able to incorporate technology into their lessons at transformational levels. The following themes emerged from data regarding teachers' perceptions of support: shared vision, realistic and supportive climate, collaboration, encouragement, job-embedded professional learning, continuous improvement, equity, and safe, legal, and ethical use. The findings of this study serve as a foundation for understanding …

In the current globalizing society, teachers are provided opportunities to move across their national borders to seek learning, professional development, and working opportunities. Technology-related professional development is particularly valued for teachers' sojourn to the technology intensive cultures. This qualitative cross-case study explored the K-12 Chinese language teachers' changes of teachers' application and perspective toward educational technology in cross-cultural teaching context through the lens of transformative learning theory. The qualitative data is collected from the interviews with 20 teacher participants in the four stages of cross-cultural sojourning: pre-departure, currently sojourning, post-sojourn, and immigrated. A qualitative cross-case analysis is conducted to compare the characteristics of teachers in different cases, and developed the complete process of the cross-cultural technology adoption and perspective. Factors contributed to the changes are also identified. Five issues related to the process are discussed. Implications and future directions were also included.

One of the essential difficulties encountered while preparing a piece for a pre-professional player is defining the piece's technical challenges and doing exercises or etude studies accordingly. Based on this fact, in my thesis, I described the technical challenges of Edouard Nanny's Dragonetti A Major concerto under the headings and suggested technical studies suitable for these difficulties. The titles represented are string crossing, bow strokes, thumb position and vertical-horizontal approaches, harmonic arpeggios and horizontal playing in harmonics, intonation and shifting, and double stops. In the last step of each heading, I associate these technical studies with an excerpt from a more advanced piece than this concerto in the double bass repertoire. Accordingly, the thesis aims to define a working path for Nanny's Dragonetti A Major Double Bass Concerto and, at the same time, to be a preliminary preparation for the more technically challenging works of the repertoire.

While female mimicry and lower status signaling hypotheses of delayed plumage maturation have received much discussion in the literature, the experimental tests of these hypotheses have been infrequent. Those experimental tests often use a simulated intruder method with artificial model intruders rather than using live conspecific birds as intruders. Subadult male painted buntings (Passerina ciris) possess delayed plumage maturation where they appear visually identical to adult females during their first potential breeding season, while adult males are strikingly different in plumage coloration. Here I test the behavioral responses in a territorial population of painted buntings that exhibits extreme delayed plumage maturation using a simulated territorial intrusion experiment to measure territorial male behavioral response when presented with live caged intruders of both subadult and adult males. Territorial adult males were significantly more likely to initiate an attack and continue to attack caged adult male intruders than compared to caged subadult male intruders. This result supports both the female mimicry and status signaling hypotheses, and does not support the cryptic hypothesis. Additionally, in anecdotal observations, territorial males occasionally performed mating display behaviors to caged subadult male intruders. These results further suggest that territorial male painted buntings may identify subadult males as potential …

Social media platforms create rich social structures, expand users' boundaries of social networks and revolutionize traditional forms of communications, social interactions and social relationships. These platforms not only facilitate the creation and sharing of news and information, but they also drive various kinds of businesses models, processes and operations, knowledge sharing, marketing strategies for brand management and socio-political discourses essential for healthy and democratic functions. As such, social media has greater implications on organizations and society brought about by individuals' social media usage patterns, and therefore, calls for further investigations. The main objective of this dissertation is to explore and offer insights into such social media usage and information sharing behaviors via data driven examination of various theories. This dissertation involves three studies that focus on factors that explain individuals' three different social media usage behaviors. Essay 1 investigates individuals' perceived importance of online affiliation, self-esteem, self-regulation and risk-benefit structure as antecedents of users' geo-tagging behavior on social media. Essay 2 examines the role of online news quality, source credibility, individuals' perception towards online civic engagement, attitude towards news sharing and social influences to understand users' news sharing behavior on social media platforms. Essay 3 seeks to examine the individuals' …

This thesis focuses on tribal engagement and tribal consultation in the United States. In the thesis, I discuss my experience working on an interdisciplinary research team completing a formal ethnographic study which was submitted to a federal agency. Using insights gained from this experience and additional experience working with American Indian tribes, I discuss historic, contemporary, and potential future strategies for involving and engaging American Indian tribes in land and resource stewardship decisions in the United States.

Wii Fit U games utilize a Wii Balance Board™ (WBB) in a manner that can provide precise feedback contingencies similarly to some forms of balance rehabilitation, thereby potentially increasing the dose of quality therapy with or without the presence of a therapist during post-brain injury rehabilitation. Additionally, an engaging video-game could improve treatment adherence, a critical aspect of making positive functional gains, by potentially increasing the rate and quality of reinforcement embedded in therapy. The present study had three aims: (1) develop a rigorous behavioral therapy for improving balance in individuals living with chronic brain injury using a Wii Fit U game and the WBB; (2) evaluate the program's effects on balance measures using a within-subject experimental design; and (3) assess social validity of behavioral gains by evaluating the program's effects on participant's "subjective balance confidence" (i.e., their Activities-Specific Balance Confidence (ABC) scores). A reversal design is proposed for use with primary study participants, wherein the experimental gameplay condition and no intervention condition are alternated for 6 to 10 weeks. A similar design was used in a truncated fashion with pilot participants, and a multiple baseline design was used with follow-up pilot participants. It was expected that participants would exhibit …

Low-cost sensors have the potential to create dense air monitoring networks that help enhance our understanding of pollution exposure and variability at the individual and neighborhood-level; however, sensors can be easily influenced by environmental conditions, resulting in performance inconsistencies across monitoring settings. During summer 2020, 20 low-cost particulate sensors were deployed with a reference PM2.5 monitor in Denton, Texas in preparation for calibration. However, from mid to late-summer, dust transported by the Saharan Air Layer moved through the North Texas region periodically, influencing the typical monitoring pattern exhibited between low-cost sensors and reference instruments. Traditional modeling strategies were adapted to develop a new approach to calibrating low-cost particulate sensors. In this study, data collected by sensors was split according to a novel dust filter into dust and non-dust subsets prior to modeling. This approach was compared with building a single model from the data, as is typically done in other studies. Random forest and multiple linear regression algorithms were used to train models for both strategies. The best performing split-model strategy, the multiple linear regression models split according to dust and non-dust subsets (combined R2 = 0.65), outperformed the best performing single-model strategy, a random forest model (R2 = 0.49). …

Secondary students with specific learning disabilities often have challenges with academic engagement and performance within the general education setting. Opportunity to respond strategies, such as student response systems, have shown promise in supporting academic engagement for students without disabilities. However, there are few studies examining the relationship between student response systems and academic engagement for older students with specific learning disabilities. The purpose of this study was to pilot the use of Google classroom as a student response system on academic participation and disruptive behavior for high school students with specific learning disability. While the study began as a multiple baseline across participants single-subject research design, the design was changed due to school closures as a result of COVID-19. A high-school student with specific learning disability participated in a study using an AB non-experimental design. The student response system resulted in an abrupt change in academic participation for the participant. The student and teacher perceived the intervention to be effective and appropriate for increasing participation and decreasing disruptive behavior. This study contributes to a limited body of research on student response systems for secondary students with specific learning disabilities.

Companies are becoming increasingly dependent on teams to drive creativity and innovation, which usually involves multiple teams working together to solve complex problems However, the first problem is that work teams do not always manage creativity and innovation well, especially when partnering with other work teams on highly complex projects that demand greater interdependence and collaboration, which can constitute as much as 90% of today's organizational projects. The second problem is that researchers struggle to define and measure creativity and innovation for the past decade resulting in significant variation both within and between creativity and innovation scales that have restricted meaningful theoretical discoveries and advances. The current study is significant because it introduces a novel instrument derived by John Turner that measures team creativity and innovation processes as a single unit, thereby raising the level of theoretical sophistication and leading to better practical applications. After conducting factor analysis, the current study validates six factors, including 36 indicators, and measures team creativity and innovation processes as complex adaptive systems (CAS). The current study recommends deploying the new instrument in other sectors beyond the IT sector and using multilevel techniques that include the individual and executive/organization levels of analysis.

Members of the elderly population is disproportionately prone to experiencing mobility impairment due to their aging bodies and as a result have frail bodies that are at a higher risk of grave injury due to falling. In order to combat this assistive mobility devices such as exoskeletons have been developed to help patients enhance their range of motion. With additive manufacturing techniques, such as fused deposition modeling (FDM), becoming a more mainstream form of design, the inclusion of lightweight polymers such as nylon 12 as primary construction materials for these devices has increased. In this thesis computer aided design (CAD) software was used to design a prototype lower body exoskeleton and simulation software was used to give the device the characteristics of Stratasys' nylon 12 carbon fiber FDM material to verify it if could be used as the primary construction material for this device when extruded from a FDM printer on either the XZ or ZX printing plane. From the simulations it was found that the material printed along the XZ plane could create a device that could withstand the weight of an average elderly male patient (200 lbs.) as well as the 35 lbs. of force applied to the …
