U.S. International ESL Students' Experiences with and Perceptions of Utilizing Mobile Technologies for English Learning
The purpose of this research was to examine ESL (English as a second language) students' current use of their mobile phones for English skill building activities outside of class in a U.S. school setting. In addition, this research reported on students' perceptions of the potential benefits of using smartphones in class for English learning. Also learners' current English related activities using mobile devices and time duration of using different phone features were studied. The literature review included smartphones, computer education, mobile learning, mobile assisted language learning (MALL), computer assisted language learning (CALL), theories of second language learning, second language learner attributes and the use of smartphones outside the classroom. An electronic survey was used to collect the quantitative data which were analyzed by descriptive and inferential statistics. The results concluded that students used mobile applications on a daily basis to read and write email, read books and news, check a dictionary, talk, text and video chat. Students used mobile phones outside of class to improve the English skills listed in the survey and the same participants perceived the potential benefits of using smartphones in class for the same English skills. Among the English skills, vocabulary exercises, finding example sentences of English words and English grammar exercises had a significant difference between out of class and in class variable. The results indicated a direction for future research on using mobile phones for ESL learning. This study also revealed a focus of practice for utilizing mobile technologies in the teaching and learning of ESL.
Preservice Teachers' Beliefs about Writing and Their Plans to Teach Writing: The Apprenticeship of Observation
Preservice teachers (PSTs) bring a plethora of knowledge and experiences to their educator preparation courses. The PSTs have also formed ideas about how to teach based on their observations during the thousands of hours they spent as students in the classroom from kindergarten through high school graduation. This phenomenon, coined by Lortie, is called the apprenticeship of observation. Past research has focused on the apprenticeship of observation in general while neglecting to specifically explore how this phenomenon influences PSTs in regards to writing. Guiding this study were three research questions: (1) what are the PSTs' beliefs about writing instruction and themselves as writers, (2) how have PSTs' experiences as students affected their beliefs about themselves as writers, and (3) how do PSTs' experiences as students influence their plans to teach writing? After conducting a thematic analysis, there are four findings that stemmed from the data. First, PSTs come to their educator preparation programs with beliefs about themselves as writers. Particularly, the PSTs believe they are either writers or non-writers, Next, PSTs believe that writing instruction should be high-quality and foster student interest. Additionally, data suggested that PSTs' past experiences as students in a writing classroom influenced the PSTs' beliefs. Particularly, the PSTs' experiences around feedback and the control they had over writing were the most discussed. Lastly, past experiences stemming from the PSTs' apprenticeship of observation formed the basis for the plans the PSTs had about teaching writing. These findings have implications for both teacher educators and the PSTs they teach. It is imperative that teacher educators take steps to uncover the beliefs and past experiences of the PSTs as these serve as a lens through which the PSTs look through during their writing methods courses. Teacher educators must also use this information as a springboard for instruction. Finally, teacher ...
Simulink® Based Design and Implementation of Wireless Sensor Networks
A wireless sensor network (WSN) is a spatially distributed network used to monitor the physical and environmental conditions such as temperature, pressure, sound, humidity, heat, etc. WSNs can be modeled using different simulation frameworks like OMNeT++, Prowler, Atarraya, PiccSIM, Network Simulator, etc. In this research, Simulink framework was used to model WSN system. The complete WSN consisting of transmitting nodes, communication channel, and receiver nodes are built in the Simulink framework. Orthogonal frequency division multiplexing technique was used to transmit the information. The implemented wireless sensor system behavior is studied using temperature as the measurement parameter at different values of signal to noise ratio. The plots of bit error rate versus signal to noise ratio and frame error rate versus signal to noise ratio are generated in the Simulink framework. It is easy to study the effect of different physical layer parameters on the performance of wireless sensor networks by implementing WSN in the Simulink framework.
P-type Doping of Pulsed Laser Deposited WS2 with Nb
Layered transition metal dichalcogenides (TMDs) are potentially ideal semiconducting materials due to their in-plane carrier transport and tunable bandgaps, which are favorable properties for electrical and optoelectronic applications. However, the ability to make p-n junctions is the foundation of semiconductor devices, and therefore the ability to achieve reproducible p- and n-type doping in TMD semiconducting materials is critical. In this work, p-type substitutional doping of pulsed laser deposited WS2 films with niobium is reported. The synthesis technique of the PLD target with dopant incorporation which also ensures host material stoichiometry is presented. Hall electrical measurements confirmed stable p-type conductivity of the grown films. Structural characterization revealed that there was no segregation phase of niobium in the fabricated films and x-ray phtoelectron spectroscopy (xps) characterization suggest that the p-type doping is due to Nb4+ which results in p-type behavior. Stable hole concentrations as high as 10E21(cm-3) were achieved. The target fabrication and thin film deposition technique reported here can be used for substitutional doping of other 2D materials to obtain stable doping for device applications.

This dissertation is about economic resilience of local governments to natural disasters. Specifically, the dissertation investigates resilience on regional level. Moreover, the dissertation also investigates growth in the green job sector in local governments. The findings indicate that local governments working with each other helps green job creation. In addition, the dissertation finds that green jobs, following disasters, experience three percent growth. This dissertation is important because it investigates the relationship between climate- related disasters and green jobs, which is an area that is under-investigated.
Evaluation of a Behavior Skills Package to Teach Caregivers to Manage Disruptive Behavior during Medical and Dental Appointments
Adults with developmental disabilities that live in large residential settings experience complications due to problem behavior when attending routine medical/dental appointments. This may result in sedation for clients for even the most routine medical/dental appointments. The purpose of this project was to develop a comprehensive staff training program that incorporated best practices to teach direct-support professionals behavior management techniques and best practices for transporting clients to and from routine medical/dental appointments. 4 direct-support professionals at a large residential care facility participated in this project. Multiple probes were conducted utilizing standard role-play exercises to evaluate caregiver acquisition of 16 specific skills related to client information, best practices for client transport, and behavior management. The results indicated that behavior skills training (BST) resulted in caregiver acquisition of all 16 skills during role-play exercises.

College Readiness and Dual Credit Participation of Alternative High School Students
The purpose of this study was to explore the extent to which alternative schools add value to the college readiness of their students, as well as to measure the capacity of alternative school students to successfully complete dual credit courses while enrolled at the alternative school. This mixed methods study utilized an exploratory approach with a descriptive research design to explore the extent to which alternative schools produce college-ready students. The Texas Success Initiative Assessment was used to measure participants' academic readiness levels in mathematics, reading, and writing. Additionally, participants had the opportunity to provide their own perspectives on their college readiness levels through a student survey and semi-structured face-to-face interview. The results of this study reveal that the college readiness levels of alternative high school students varied across academic areas. Of the tested participants, 41.1% were college ready in reading, 52.1% in writing, and 16.7% in mathematics. Additionally, the findings reveal that dual credit course participation was not a viable option because of course prerequisites and the amount of time needed to complete dual credit courses. Results of this study expand on the literature to provide a better understanding of the effectiveness of alternative school programs, the college readiness levels of alternative high school students, and the capacity of alternative high school students to successfully complete college coursework while in high school.
When to Say It: Establishing a Verbal Cue
Dog trainers sometimes teach verbal cues by saying the cue as the dog is performing the desired behavior. However, there is disagreement about when to say the cue. In this study, a pet dog was trained to go to three different apparatus, the cue for each of which was given at a different time, in a multi-element design. The cue "hoop" was given just as the dog began to move to the hoop apparatus. The cue "carrier" was given as the dog was stepping into the carrier apparatus. The cue "platform" was given after the dog was sitting on the platform apparatus. To test if the dog had learned the cues, the trainer had the dog sit and gave the cue. During testing, if only the correct apparatus was present, the dog responded to all three cues. However, when all three apparatus were present, the dog only responded correctly to the "hoop" cue. This suggests that giving the cue just as the learner is beginning to perform the desired behavior is the most effective teaching method.
Musical Training through Operant Selection
Language is a cultural construct, and the relationship between words is taught. Priming research has long investigated the relationship between related and unrelated words. Similar research has been seen in music relationships, but most of these investigate harmonic relations despite the melodic relationship being the one listeners are mostly likely to describe. Further, these studies typically measure existing relationships and do not attempt to teach a new relationship, nothing that most adults are experienced musical listeners. This study seeks to establish a new melodic relationship (the enigmatic Scale) in addition to a familiar one (the major Scale) while measuring response time to the musical sequences. A baseline was conducted in which participants listened to a musical sequence and selected via response box if the final note is consonant (major Scale) or dissonant (enigmatic Scale). Following baseline a training section occurred in which participants heard sequences ranging from 2-7 notes and were provided feedback for correct and incorrect responses. Following completion of the training participants completed a post-test identical to baseline. Behavioral results are discussed in relation to Palmer's (2009) concept of the repertoire.
Historical Memory and Ethics in Spanish Narrative
This study traces the current status of Spanish ethics as seen through the optics of historical memory. Starting from the Spanish Civil War in 1936, the thesis relates contemporary themes to their proposed origin throughout three additional distinctive eras of the 20th and 21st century in Spain: 1982-1996 (Socialist Spain), 1997-2010 (Post-modern Spain), and 2011-present (current Spain). Spanish narratives ranging from Los Abel by Matute, La magnitud de la tragedia by Monzó, "Fidelidad" of Ha dejado de llover by Barba and Las fosas de Franco by Silva are contextualized through their ethical architecture, in accordance with their socio-political context, and relationship to past historical traumas. This work proposes that the themes of anticlericalism, the pursuit of social equality, anti bureaucracy, and political distrust are trends culminating from Kohlberg's third level of morality. The thesis aims to be an exposition and legitimization of different ethical schemas that might otherwise be polarized as wrong and inferior by others.
Shear and Bending Strength of Cold-Formed Steel Solid Wall Panels Using Corrugated Steel Sheets for Mobile Shelters
The objective of this thesis is to determine if the single sided resistance spot weld (RSW) can be used as a feasible connection method for cold formed steel (CFS) shear walls subject to lateral force of either seismic or wind loads on mobile shelters. The research consisted of three phases which include: a design as a 3D BIM model, connection tests of the resistance spot weld, and full-scale testing of the designed solid wall panels. The shear wall testing was conducted on specimens with both resistance spot weld and self-drilling screws and the results from tests gave a direct comparison of these connections when the solid wall panel was subjected to in-plane shear forces. The full-scale tests also included 4-point bending tests which was designed to investigate the wall panel's resistance to the lateral loads applied perpendicularly to the surface. The research discovered that the singled sided resistance spot weld achieved similar performance as the self-drilling screws in the applications of CFS wall panels for mobile shelters. The proposed single sided resistance spot weld has advantages of low cost, no added weight, fast fabrication, and it is a feasible connection method for CFS wall panels.
Return to Sport: Improving Athletes' Confidence and Mindset Post-ACL Surgery
This study explored the impact of three psychological interventions over seven weeks - goal setting (GS), GS and imagery (IM), and GS and mindful self-compassion (MSC) - on 20 athletes' (Mage = 16.75 years) pain, cognitive appraisal, depression reinjury anxiety, psychological readiness to return to sport, and range of motion (ROM). IM and GS interventions have demonstrated initial effectiveness; however, no study has examined MSC in relation to post-ACL recovery. All athletes experienced significant decrease in pain (F(2) = 97.30, p = .000) from Week 1 to Week 7 and a significant increase in ROM from Week 2 to Week 7 (F(1) = 77.93, p = .000). All athletes experienced significantly higher depression at Week 1 compared to both Week 2 and Week 7 (F(2) = 9.01, p = .001), and significantly higher difficulty coping with their injury at Weeks 1 and 2 compared to Week 7 (F(2) = 6.32, p = .005). There were no statistically significant effects found between the intervention groups at Weeks 1, 2, and 7. However there were moderate effect sizes between interventions which suggest MSC and IM could help athletes cope with their injury during the first few weeks after surgery, and GS may contribute towards less depression at seven weeks post-surgery. Limitations include small sample size, low power, and use of self-report measures. Results have implications for orthopedic surgeons, physical therapists, and health professionals working with athletes recovering from serious sport injury.
It's Going to be Different, but It's Going to be Okay: Caregiver Perspectives on Autism, Culture and Accessing Care
Through ethnography influenced by public health and anthropological theory, I explored the cultural perceptions of autism among eight caregivers whose children received services from a local Dallas-Fort Worth autism treatment organization. Participant observations and semi-structured interviews with caregivers and program employees provided a rich and nuanced view into the state of care currently available in the DFW area while also highlighting areas for improvement. This research will be used to not only identify the barriers faced by North Texas Families while seeking out care,but also the strategies the organization uses when connecting with families from different backgrounds.
Understanding the Perceptions and Indications of the Goals and Unique Aspects of the Foundations for Success (FFS) Curriculum Model: A Case Study in a North Texas Private Preschool
This quantitative and qualitative case study examined the educators' perceptions of both the goals and unique aspects of the foundations for success (FFS) curriculum model. Specifically, this study was designed to explain the experiences of 55 early childhood educators and administrators who all had similar exposure to the FFS curriculum model. This study sought to understand the educators' perceptions of the specific goals of using pertinent curriculum and instruction terminology and the parallel process of content language, connecting the importance of developmentally appropriate practices (DAP) and learning standards and readiness for kindergarten. In the same way, the perceptions of the unique aspects of the value based curriculum, the use of reflective supervision and the use of design thinking were gathered and interpreted. This study looked closely into program successes, challenges and future implications of the FFS curriculum model. This study also considered the extent to which future implementations of the model could change the current interdependent relationship between early childhood education and the primary grades. The researcher analyzed the perceptions, utilizing the Likert-value survey instrument responses, the open-ended survey responses, along with the focus group responses to triangulate the findings. Common themes shared across all data collection were evaluated and described. The most apparent themes derived from the findings included the following: the importance of relationships; the importance of accountability and the role language plays; the necessity of the consideration of children's interest for optimal development; and the recognition of intentional planning, revisiting and reflection to the process of the FFS curriculum model. Overall, the FFS curriculum model was determined to be a curriculum model that takes educators on a continuous journey of thinking and learning. Evidence was gathered for the FFS curriculum model that implicated the possibility for replication of the model in other schools, as well as further ...
The Aesthetics of Sin: Beauty and Depravity in Early Modern English Literature
This dissertation argues that early modern writers such as William Shakespeare, Thomas Middleton, George Herbert, John Milton, and Andrew Marvell played a critical role in the transition from the Neoplatonic philosophy of beauty to Enlightenment aesthetics. I demonstrate how the Protestant Reformation, with its special emphasis on the depravity of human nature, prompted writers to critique models of aesthetic judgment and experience that depended on high faith in human goodness and rationality. These writers in turn used their literary works to popularize skepticism about the human mind's ability to perceive and appreciate beauty accurately. In doing so, early modern writers helped create an intellectual culture in which aesthetics would emerge as a distinct branch of philosophy.
Design, Construction, and Application of an Electrostatic Quadrupole Doublet for Heavy Ion Nuclear Microprobe Research
A nuclear microprobe, typically consisting of 2 - 4 quadrupole magnetic lenses and apertures serving as objective and a collimating divergence slits, focuses MeV ions to approximately 1 x 1 μm for modification and analysis of materials. Although far less utilized, electrostatic quadrupole fields similarly afford strong focusing of ions and have the added benefit of doing so independent of ion mass. Instead, electrostatic quadrupole focusing exhibits energy dependence on focusing ions. A heavy ion microprobe could extend the spatial resolution of conventional microprobe techniques to masses untenable by quadrupole magnetic fields. An electrostatic quadrupole doublet focusing system has been designed and constructed using several non-conventional methods and materials for a wide range of microprobe applications. The system was modeled using the software package "Propagate Rays and Aberrations by Matrices" which quantifies system specific parameters such as demagnification and intrinsic aberrations. Direct experimental verification was obtained for several of the parameters associated with the system. Details of the project and with specific applications of the system are presented.
Motivic and Voice-Leading Coherence in the Improvisations of Saxophonist Chris Cheek
Saxophonist Chris Cheek has been a reference for his work as a sideman with some of the most established jazz artists in the international jazz scene of the last twenty-five years. Despite his importance, there is lack of detail in the available publications about Cheek. The short length and journalistic character of the publications only produce surface descriptions of Cheek's style. There is a need to further describe the melodic elements present in Chris Cheek's style in order to have a better understanding of the implications and importance of these elements across the history of jazz saxophone and jazz pedagogy. In the past, several scholarly works have described the improvisational styles of jazz musicians using a multitude of analytical tools. The design of those studies often fails to provide a comprehensive view of the improviser's style because of the limited scope of the analyzed sources or the specific focus of the analysis. This analytical study presents a comprehensive view of Chris Cheek's style through the motivic and voice-leading analyses of six improvisations by the saxophonist. This design allows the study to discern between motivic development processes, melodic structures, formulaic material, and harmonic structures that belong to the saxophonist's idiom. By presenting the elements in Cheek's style, this study is able to show the importance of motivic and voice-leading coherence in jazz pedagogy as well as the importance of Cheek's style as a reference for lyricism.
Non-Isothermal Laser Treatment of Fe-Si-B Metallic Glass
Metallic glasses possess attractive properties, such as high strength, good corrosion resistance, and superior soft magnetic performance. They also serve as precursors for synthesizing nanocrystalline materials. In addition, a new class of composites having crystalline phases embedded in amorphous matrix is evolving based on selective crystallization of metallic glasses. Therefore, crystallization of metallic glasses and its effects on properties has been a subject of interest. Previous investigations from our research group related to laser assisted crystallization of Fe-Si-B metallic glass (an excellent soft magnetic material by itself) showed a further improvement in soft magnetic performance. However, a fundamental understanding of crystallization and mechanical performance of laser treated metallic glass was essential from application point of view. In light of this, the current work employed an integrated experimental and computational approach to understand crystallization and its effects on tensile behavior of laser treated Fe-Si-B metallic glass. The time temperature cycles during laser treatments were predicted using a finite element thermal model. Structural changes in laser treated Fe-Si-B metallic glass including crystallization and phase evolution were investigated with the aid of X-ray diffraction, differential scanning calorimetry, resistivity measurements, and transmission electron microscopy. The mechanical behavior was evaluated by uniaxial tensile tests with an InstronTM universal testing machine. Fracture surfaces of the metallic glass were observed using scanning electron microscopy and site specific transmission electron microscopy. Fe-Si-B metallic glass samples treated with lower laser fluence (<0.49 J/mm2) underwent structural relaxation while higher laser flounces led to partial crystallization. The crystallization temperature experienced an upward shift due to rapid heating rates of the order of 104 K/s during laser treatments. The heating cycle was followed by termination of laser upon treatment attainment of peak temperature and rapid cooling of the similar order. Such dynamic effects resulted in premature arrest of the crystallite growth leading ...
Ethnic and Sexual Minority Differences in the Prediction of Disordered Eating and Exercise Behaviors in College Men
Despite growing evidence of their prevalence, clinical and subclinical disordered eating behaviors among men continue to be understudied phenomena. When compared to females, predictors of male disordered eating vary across ethnic groups, suggesting cultural influences on disordered eating. Moreover, gay and bisexual men experience pronounced levels of body dissatisfaction, sensitivity to societal body image standards, and subsequent disordered eating when compared to straight men and gay women. This study investigated possible differences in prediction of disordered eating among intersections of male ethnicity and sexuality. We approached this question through a transtheoretical lens that integrated intersectionality and minority stress theories. Archival data from a sample of African American, Latino, and White college men were analyzed using hierarchical multiple regression. Predictors of emotional and binge eating behaviors differed across ethnicity, in that body dissatisfaction and media internalization for African American and Latino males exhibit the strongest unique associations with emotional and binge eating behaviors, while the strongest unique predictors of emotional and binge eating behaviors among White males are depressive symptoms and low self-esteem. Moreover, African American sexual identity and depressive symptoms interact, as gay or bisexual men report stronger unique associations between depression symptoms and emotional and binge eating. All predictors (i.e., body dissatisfaction, depression symptoms, low self-esteem, media internalization, and sexual minority identity) were unable to explain sufficient variance in over exercise behaviors in African American men. Results suggest ethnicity and sexual orientation are meaningful to the experience of disordered eating in men, and that underlying mechanisms may exhibit differing associative patterns across ethnic identity. Clinicians working with ethnically and sexually diverse male disordered eating populations may use the results to better inform treatment interventions and conceptualization. These findings also support the value of intersectional quantitative methodology and the limits of relying on single-axis identity as a predictive element.
Location Estimation and Geo-Correlated Information Trends
A tremendous amount of information is being shared every day on social media sites such as Facebook, Twitter or Google+. However, only a small portion of users provide their location information, which can be helpful in targeted advertising and many other services. Current methods in location estimation using social relationships consider social friendship as a simple binary relationship. However, social closeness between users and structure of friends have strong implications on geographic distances. In the first task, we introduce new measures to evaluate the social closeness between users and structure of friends. Then we propose models that use them for location estimation. Compared with the models which take the friend relation as a binary feature, social closeness can help identify which friend of a user is more important and friend structure can help to determine significance level of locations, thus improving the accuracy of the location estimation models. A confidence iteration method is further introduced to improve estimation accuracy and overcome the problem of scarce location information. We evaluate our methods on two different datasets, Twitter and Gowalla. The results show that our model can improve the estimation accuracy by 5% - 20% compared with state-of-the-art friend-based models. In the second task, we also propose a Local Event Discovery and Summarization (LEDS) framework to detect local events from Twitter. Many existing algorithms for event detection focus on larger-scale events and are not sensitive to smaller-scale local events. Most of the local events detected by these methods are major events like important sports, shows, or big natural disasters. In this work, we propose the LEDS framework to detect both bigger and smaller events. LEDS contains three key steps: 1) Detecting possible event related terms by monitoring abnormal distribution in different locations and times; 2) Clustering tweets based on their key terms, ...
Ex-Offender Reentry: An Analysis of Current Policies and Programs
Recidivism rates among ex-offender populations have consistently remained high. With over 600,000 ex-offenders being released from prison each year, reducing the rate of recidivism among the ex-offender class has become a highly debated issue. Ensuring ex-offenders successfully reintegrate into the community post-incarceration may help to reduce recidivism rates. Through a qualitative thematic analysis, this study examined various policies and program that may impact recidivism rates among ex-offenders. The policies and programs reviewed in this study were categorized among six main themes which were identified in prior literature as the most crucial elements needed for successful reintegration. The findings indicate that while many policy changes have been made to positively impact ex-offender reintegration by allowing initial access to services post-release from prison, more should be done to ensure ex-offenders actually receive needed services.
School System Improvement through Building Leadership, Adult Learning, and Capacity: A Consideration of Instructional Rounds as a Systemic Improvement Practice
The problem of the study was determining the supportive conditions related to instructional rounds (rounds) to understand better what conditions may allow for sustained systemic improvement over time. Three Texas school districts were studied to understand the perceptions of district leaders, principals, teacher leaders, and teachers with regard to the sustainability of instructional rounds as a systemic improvement practice, the supportive conditions necessary for sustainability, the salient characteristics that differentiated rounds from other improvement practices, and the potential of rounds to build organizational capacity. Observation of network rounds visits and document analysis was conducted to determine alignment of perception with observation and documents. Findings include perceptions, themes, and critical factors for the sustainability of rounds as an effective systemic improvement practice. Supportive conditions emerged as the most significant perception expressed by the participants. Implications for action for school districts beginning or continuing implementation of instructional rounds are suggested based upon findings from participant perceptions and observation of networks. Suggestions for future research are shared. With supportive conditions in place, instructional rounds has the potential to serve as an effective systemic improvement practice.
Practices that Influence Instructional Coaches' Perceptions of Effectiveness
As instructional coaches are being implemented across the country, their purpose is reviewed, as well as which types of instructional coaching tend to have the most impact on teachers' instructional growth. In this study, I explored instructional coaching and coaches' perceived effectiveness as they work with teachers. A look at the effect of non-evaluative feedback with an instructional coach, and how that helps sustain teachers' pedagogical practice, is taken into consideration as coaches' work towards developing teacher efficacy. I examined instructional coaching through the conceptual framework of professional development and change. This qualitative study included a focus group, personal narratives, and individual interviews to analyze the components of successful instructional coaching models, and how well instructional coaches feel supported as they work with teachers. Findings demonstrated that instructional coaches perceive their work with teachers to be effective and provided information on the practices and conditions that surround their work. The information gained from the study provides a resource for district leaders to evaluate a current coaching model program, or implement a new coaching model program, within their district.
Supportive Systems for Building Capacity of the Elementary Instructional Coach
The purpose of this qualitative case study was to examine the systems in place to build the capacity of elementary instructional coaches in a fast-growth district. Through syntheses of research from educational scholars, the conceptual framework was developed with a focus on building capacity of instructional coaches in an ever-changing environment of fast-growth through the lens of professional learning communities, human and social capital, and support from district and campus administration. This study assessed the perceptions of six instructional coaches, six principals, and six district leaders from Rose ISD regarding the school district's support for building the capacity of instructional coaches within the elementary instructional coaching program. The three-part data collection process included document analysis, in-depth interviews, and focus group interviews to support triangulation of data. Through the a priori coding process, the following four themes emerged that highlight key components needed to support district leaders in establishing systems to build the capacity of instructional coaches in an ever-changing environment caused by fast growth: structured time for professional learning, program clarity, collaborative support systems, and implementation of a professional learning community framework. This study revealed a specific need to further understand systems for monitoring and evaluating the effectiveness of the instructional coaching program in an ever-changing environment of a fast-growth district.

This dissertation presents beamforming designs. Using novel techniques and methods, the performance of the beamforming is improved on dual-band, tri-band, flexible function, tunable function in THz, and dynamic controllability on incident wave.
Exposing the Spectacular Body: The Wheel, Hanging, Impaling, Placarding, and Crucifixion in the Ancient World
This dissertation brings the Ancient Near Eastern practice of the wheel, hanging, impaling, placarding, and crucifixion (WHIPC) into the scholarship of crucifixion, which has been too dominated by the Greek and Roman practice. WHIPC can be defined as the exposure of a body via affixing, by any means, to a structure, wooden or otherwise, for public display (Chapter 2). Linguistic analysis of relevant sources in several languages (including Egyptian hieroglyphics, Sumerian, Hebrew, Hittite, Old Persian, all phases of ancient Greek, and Latin) shows that because of imprecise terminology, any realistic definition of WHIPC must be broad (Chapter 3). Using methodologies and interdisciplinary approaches drawn from art history, archaeology, linguistic analysis, and digital humanities, this work analyzes scattered but abundant evidence to piece together theories about who was crucified, when, how, where, and why. The dissertation proves that WHIPC records, written and visual, were kept for three primary functions: to advertise power, to punish and deter, and to perform magical rituals or fulfill religious obligations. Manifestations of these three functions come through WHIPC in mythology (see especially Chapter 4), trophies (Chapter 5), spectacles, propaganda, political commentary, executions, corrective torture, behavior modification or prevention, donative sacrifices, scapegoat offerings, curses, and healing rituals. WHIPC also served as a mode of human and animal sacrifice (Chapter 6). Regarding the treatment of the body, several examples reveal cultural contexts for nudity and bone-breaking, which often accompanied WHIPC (Chapter 7). In the frequent instances where burial was forbidden a second penalty, played out in the afterlife, was intended. Contrary to some modern assertions, implementation of crucifixion was not limited by gender or status (Chapter 8). WHIPC often occurred along roads or on hills and mountains, or in in liminal spaces such as doorways, cliffs, city gates, and city walls (Chapter 9). From the Sumerians to the ...
African American Student Placement in Disciplinary Alternative Education Programs
The purpose of this study was to determine the relationship (predicative capability) between selected variables, specifically, African American student enrollment, teacher ethnicity, and urban or rural district classification and the number of African American student placements in a disciplinary alternative education program (DAEP). The study used a non-experimental ex post facto design. Archival data from the Texas Education Agency were used to identify Texas schools that sent African American students to a DAEP during the 2013-2014 school year. Archival data from the Texas Education Agency were also used to identify African American student enrollment and teacher ethnicity for the selected school districts. Finally, archival data from the Texas Department of Agriculture were used to identify district classifications of urban or rural. Participants in this study consisted of 187 school districts that placed African American students in a DAEP during the 2013-2014 school year. Based on the findings, teacher ethnicity and African American student enrollment are statistically significant contributions to African American student placement in a DAEP. Urban or rural district classification is not a statistically significant predictor in the same placements. Results of this study add to existing literature by confirming that there is an overrepresentation of African American student placements in DAEPs and suggesting possible ways to combat this epidemic.
Evaluation of Call Mobility on Network Productivity in Long Term Evolution Advanced (LTE-A) Femtocells
The demand for higher data rates for indoor and cell-edge users led to evolution of small cells. LTE femtocells, one of the small cell categories, are low-power low-cost mobile base stations, which are deployed within the coverage area of the traditional macro base station. The cross-tier and co-tier interferences occur only when the macrocell and femtocell share the same frequency channels. Open access (OSG), closed access (CSG), and hybrid access are the three existing access-control methods that decide users' connectivity to the femtocell access point (FAP). We define a network performance function, network productivity, to measure the traffic that is carried successfully. In this dissertation, we evaluate call mobility in LTE integrated network and determine optimized network productivity with variable call arrival rate in given LTE deployment with femtocell access modes (OSG, CSG, HYBRID) for a given call blocking vector. The solution to the optimization is maximum network productivity and call arrival rates for all cells. In the second scenario, we evaluate call mobility in LTE integrated network with increasing femtocells and maximize network productivity with variable femtocells distribution per macrocell with constant call arrival rate in uniform LTE deployment with femtocell access modes (OSG, CSG, HYBRID) for a given call blocking vector. The solution to the optimization is maximum network productivity and call arrival rates for all cells for network deployment where peak productivity is identified. We analyze the effects of call mobility on network productivity by simulating low, high, and no mobility scenarios and study the impact based on offered load, handover traffic and blocking probabilities. Finally, we evaluate and optimize performance of fractional frequency reuse (FFR) mechanism and study the impact of proposed metric weighted user satisfaction with sectorized FFR configuration.

In addition to fair use, there are a variety of other exceptions built into the copyright law that don’t get as much attention.This paper argues that as there is no digital first sale, libraries can continue to use 17 USC ​§ ​109 for physical collections and are safe to lend the books they own without worrying about copyright problems.
Bureaucracy: A Love Story
Bureaucracy usually only becomes visible when it stops working—when a system fails, when an event gets off schedule, when someone points to a problem or glitch in a carefully calibrated workflow. But Bureaucracy: A Love Story draws together research done by scholars and students in the Special Collections at the University of North Texas to illuminate how bureaucracy structures our contemporary lives across a range of domains. People have navigated bureaucracy for centuries, by creating and utilizing various literary and rhetorical forms—from indexes to alphabetization to diagrams to blanks—that made it possible to efficiently process large amounts of information. Contemporary bureaucracy is likewise concerned with how to collect and store information, to circulate it efficiently, and to allow for easy access. We are interested both in the conventional definition of bureaucracy as a form of ordering and control connected to institutions and the state, but we also want to uncover how people interacted—often in creative ways—with the material forms of bureaucracy.
Exploring the Process of Developing a Glocally Focused Art Curriculum for Two Communities
The world is becoming progressively interconnected through technology, politics, culture, economics, and education. As educators we strive to provide instruction that prepares students to become active members of both their local and global communities. This dissertation presents one possible avenue for engaging students with art and multifaceted ideas about culture, community, and politics as it explores the possibilities for creating a community-based, art education curriculum that seeks a merger of global and local, or "glocal" thinking. Through curriculum action research, I explored the process of writing site-specific curriculum that focuses on publicly available, local works of art and encourages a connection between global experiences and local application. I have completed this research for two communities, one in Ohio and one in Texas, and investigated the similarities and differences that exist in the process and resulting curriculum for each location. Through textual analysis, interviews, curriculum writing, and personal reflections, I identified five essential components of a community-based, glocal art education curriculum: flexibility, authenticity, connectedness, glocal understandings, and publicly available art. Additionally, I developed a template for writing glocally focused, community-based art education curriculum and produced completed curricular units for each of the communities. Finally, I have made suggestions for the future study and development of glocally focused, art education curriculum.
