Accelerated Degree Program Faculty: Motivation to Teach
Adult educators are a growing part of American higher education. Because of their increasing prominence in adult education, it is essential to understand what roles these educators play and what motivates them to remain in the profession despite poor work prospects and conditions. Research to date, however, focuses primarily on the adult learner and not the adult educator. The purpose of this qualitative, multiple-case study was to explore the role and motivation for teaching of adult educators employed as adjunct faculty in an accelerated degree program at a small, liberal arts college in the northwest United States. Purposeful sampling was used to select the five participants for the study. All participants taught in the program for more than five years and were considered to be successful in their positions by peers, students, and administrators. The study employed a preliminary demographic survey to solicit initial background data on the instructors. Other data collection included in-depth, open-ended, face-to-face interviews, document analysis, and classroom observation. The results showed that all five participants identified the following roles and assumed them in the classroom: (a) facilitator, (b) listener, (c) specialist, (d) guide, (e) adviser, and (f) co-learner or colleague. Further results showed that all five participants were motivated to teach in the program for reasons other than monetary compensation. Although participants shared different levels of personal commitment to the institution, they all expressed extensive commitment to teaching, their discipline, and students. Motivating factors for teaching were (a) opportunity to teach part time, (b) love for the subject, (c) opportunity to gain more expertise in the field, (d) opportunity to grow and learn, (e) opportunity to give back, and (f) student success and growth. A major practical implication of this study is that adjunct faculty in an adult education program are motivated to teach for different reasons, but the primary motivation can be seen as altruistic versus monetary and practical. If college administrators want to produce and retain successful adjunct faculty, they must recruit and hire those individuals whose motivation for teaching is altruistic with a desire to enrich the lives of students. digital.library.unt.edu/ark:/67531/metadc849699/
Addressing Social Elements of Wildfire: Risk, Response, and Recovery in Highland Village, TX
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 the impact even further by informing the public of their risk, clearing natural areas of dead brush, sharing preparedness and evacuation information via social media and newsletters, and planning relief stations for those who may have been impacted. digital.library.unt.edu/ark:/67531/metadc849756/
The adoption, management, and performance of local government investment pools: A comparative analysis of state practices.
This dissertation examines the factors influencing a state’s decision to adopt a local government investment pool (LGIP), the institutional arrangements used in managing them, and the effect of the institutional types on LGIP performance. The dissertation extends the policy adoption theory with insights from investment theory to demonstrate that management credibility influences the likelihood of a state’s LGIP adoption. The study finds that the quality of financial management, the quality of professional leadership, proximate state neighbors who have previously adopted an LGIP, and economic factors determine a state’s proclivity to policy adoption. The dissertation also describes the institutional arrangements used in managing LGIPs and develops typologies based on their institutional arrangements. The dissertation compares LGIPs depending on the risk aversion of their institutional arrangements. The research extends the risk-return tradeoff in investment theory to LGIP institutional arrangements. The empirical findings show that LGIP institutional arrangement that has greater risk report higher performance. The dissertation also finds that competition in the LGIP market due to multiple vendors, and periods of economic recession account for higher performance because of higher risk-taking behaviors associated with them. This dissertation promotes public funds investment laws that emphasize prudent management of government finances and guides managers of the public purse on the types of institutional choices that optimize returns with minimal risk. digital.library.unt.edu/ark:/67531/metadc849621/
AirSniffer: A Smartphone-Based Sensor Module for Personal Micro-Climate Monitoring
Environmental factors can have a significant impact on an individual's health and well-being, and a primary characteristic of environments is air quality. Air sensing equipment is available to the public, but it is often expensive,stationary, or unusable for persons without technical expertise. The goal of this project is to develop an inexpensive and portable sensor module for public use. The system is capable of measuring temperature in Celsius and Fahrenheit, heat index, relative humidity, and carbon dioxide concentration. The sensor module, referred to as the "sniffer," consists of a printed circuit board that interconnects a carbon dioxide sensor, a temperature/humidity sensor, an Arduino microcontroller, and a Bluetooth module. The sniffer is small enough to be worn as a pendant or a belt attachment, and it is rugged enough to consistently collect and transmit data to a user's smartphone throughout their workday. The accompanying smartphone app uses Bluetooth and GPS hardware to collect data and affix samples with a time stamp and GPS coordinates. The accumulated sensor data is saved to a file on the user's phone, which is then examined on a standard computer. digital.library.unt.edu/ark:/67531/metadc849691/
An Analysis of Educational Technology Publications: Who, What and Where in the Last 20 Years
This exploratory and descriptive study examines research articles published in ten of the top journals in the broad area of educational technology during the last 20 years: 1) Educational Technology Research and Development (ETR&D); 2) Instructional Science; 3) Journal of the Learning Sciences; 4) TechTrends; 5) Educational Technology: The Magazine for Managers of Change in Education; 6) Journal of Educational Technology & Society; 7) Computers and Education; 8) British Journal of Educational Technology (BJET); 9) Journal of Educational Computing Research; and 10) Journal of Research on Technology in Education. To discover research trends in the articles published from 1995-2014, abstracts from all contributing articles published in those ten prominent journals were analyzed to extract a latent semantic space of broad research areas, top authors, and top-cited publications. Concepts that have emerged, grown, or diminished in the field were noted in order to identify the most dominant in the last two decades; and the most frequent contributors to each journal as well as those who contributed to more than one of the journals studied were identified. digital.library.unt.edu/ark:/67531/metadc849761/
Analysis of Factors for Successful State-Level Support of Low-Performing Schools
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 have implications for PSP selection, professional development, and evaluation. digital.library.unt.edu/ark:/67531/metadc849605/
An Analysis of the Leadership Competency Frameworks of Nontraditional Principal Preparation Programs
This study explored the competency frameworks of nontraditional principal preparation programs to determine how they aligned to research-based best practices for school leaders. The research questions that guided this work were: To what degree are the McREL 21 Leadership Responsibilities addressed in the competency frameworks of nontraditional principal preparation programs? How do the leaders of the nontraditional principal preparation programs view the degree to which their competencies include the McREL 21 Leadership Responsibilities? A multi-case study analysis was conducted that compared the competency frameworks of four nontraditional principal preparation programs. The Knowledge is Power Program (KIPP), New Leaders, New York City Leadership Academy (NYCLA), and Teaching Trust were the nontraditional programs selected for this study. Leaders from the four organizations were interviewed. The findings from the research illustrated that a majority of the McREL 21 Leadership Responsibilities were included in the competency frameworks of nontraditional principal preparation programs. The study revealed that four of the McREL 21 were not included in any of the competency frameworks. Another finding was the lack of focus on talent management and personal dispositions in the McREL 21 Leadership Responsibilities. Nontraditional principal preparation programs are a growing avenue for principal preparation, as such their use of research on principal success was promising digital.library.unt.edu/ark:/67531/metadc849719/
An Analytical Study of Paradox and Structural Dualism in the Music of Ludwig van Beethoven
Beethoven's rich compositional language evokes unique problems that have fueled scholarly dialogue for many years. My analyses focus on two types of paradoxes as central compositional problems in some of Beethoven's symphonic pieces and piano sonatas. My readings of Beethoven's Piano Sonata No. 27 (Op. 90), Symphony No. 4 (Op. 60), and Symphony No. 8 (Op. 93) explore the nature and significance of paradoxical unresolved six-four chords and their impact on tonal structure. I consider formal-tonal paradoxes in Beethoven's Tempest Sonata (Op. 31, No. 2), Ninth Symphony (Op. 125), and Overture die Weihe des Hauses (Op. 124). Movements that evoke formal-tonal paradoxes retain the structural framework of a paradigmatic interrupted structure, but contain unique voice-leading features that superimpose an undivided structure on top of the "residual" interrupted structure. Carl Schachter's observations about "genuine double meaning" and his arguments about the interplay between design and tonal structure in "Either/Or" establish the foundation for my analytical approach to paradox. Timothy Jackson's reading of Brahms' "Immer leiser word meine Schlummer" (Op. 105, No. 2) and Stephen Slottow's "Von einem Kunstler: Shapes in the Clouds" both clarify the methodology employed here. My interpretation of paradox involves more than just a slight contradiction between two Schenkerian readings; it involves fundamentally opposed readings, that both result from valid, logical lines of analytical reasoning. In my view, paradoxes could be considered a central part of Beethoven's persona and philosophy. Beethoven's romantic endeavors and his relationships with mentors suggest that paradoxes might have been central to his bravura. Furthermore, Beethoven's familiarity with the politics of the French Revolution and Shakespearean literature suggest that paradoxes in some pieces (including the Ninth Symphony) could be metaphorical representations of his ideology. However, I do not attempt to explicitly link specific style features to extra-musical ideas. Modern Schenkerian scholars continue to expand and refine Schenker's formal-tonal models as well as his concept of interruption. In my view, by considering paradox as a focal compositional problem, we can better understand some of the formal-tonal issues and shifting allegiances in Beethoven's music and take another step beyond the rigidity of some paradigmatic formal-tonal prototypes. digital.library.unt.edu/ark:/67531/metadc849697/
The Art of Borrowing: Quotations and Allusions in Western Music
Music travels across the past in the form of composers borrowing from each other. Such musical borrowings and quotations involve not only the use of melodic materials but also musical structures, texts, symbolism and other types of inspiration. The pre-existing musical idea being used is linked to a specific memory of a particular composer and time. The artistic allusions of composers connect the present and the past. Music also travels across the present and into the future. The outcome of contemporary composers borrowing from each other influences the present period and affects later composers' musical inspiration, i.e., it affects future composers, and therefore, the future. Composers frequently refer to melodies or musical idea from contemporaries and reinterpret them in their own compositions. This is largely because composers do not write in isolation and have been inspired and influenced by contemporary musicians and cultural contexts. However, these musical borrowings sometimes raise questions about the composers' creativity and authenticity. This is largely due to the nature of inspiration and imagination, which determines who or what is original. With this in mind, why do composers still borrow musical ideas despite the risks involved? In what ways do they overcome criticism and demonstrate the excellence of their own compositions while referring to the work of others? In what ways do artistic allusions influence new compositions? In this dissertation, I attempt to examine these questions and address the reasons for and the effects of musical quotations and allusions. digital.library.unt.edu/ark:/67531/metadc849772/
Background, Compositional Style, and Performance Considerations in the Clarinet Works of David Baker: Clarinet Sonata and Heritage: A Tribute to Great Clarinetists
David Baker (b. 1931) is an educator, composer, and jazz legend. He has composed at least fifteen works that include the clarinet. Baker’s Clarinet Sonata (1989) has become a standard of clarinet repertoire and a popular recital inclusion. His chamber work Heritage: A Tribute to Great Clarinetists (1996) interweaves solo transcriptions of five jazz clarinetists. The compositional style of Baker’s clarinet works frequently links jazz and classical idioms. The two works discussed in this document are excellent examples for classically trained musicians who would like to increase their ability and experience in interpreting jazz styles. The purpose of this document is: (1) to provide background, style, and performance considerations for Baker’s Clarinet Sonata and Heritage: A Tribute for Great Clarinetists, for Clarinet, Violin, Piano and Double Bass; (2) based on these style elements, to provide suggestions for interpreting jazz-style works for classically trained clarinetists; and (3) to archive Baker’s published and unpublished clarinet compositions. Appendices include transcripts of interviews with David Baker and other experts in this field (James Campbell, Rosana Eckert, Mike Steinel and Steven Harlos). digital.library.unt.edu/ark:/67531/metadc849742/
A Behaviorally Planned Community of Practice: A Description and Evaluation of one Area of Staff Development
Staff training packages combining instructions, modeling, practice, and feedback have been shown to be effective in demonstrating skills to work in early intensive behavioral intervention, but maintenance and generalization of the skills trained are often not addressed. Establishing a community of practice, in which staff members continue to learn and develop new skill sets from one another through shared experiences and information, may lead to the endurance and maintenance of desired staff behavior over time. The purpose of the current study is to evaluate the effects of a behaviorally designed community of practice on staff use of socially embedded consequences. The effects of the training procedure were evaluated using a concurrent multiple baseline design across two sites (7 staff members). The results suggest that the behaviorally planned community of practice was effective in reinforcing and maintaining staff use of socially embedded consequences for at least 5 to 9 weeks. Additionally, the number of learning opportunities provided by the staff and social engagement between staff and child increased. digital.library.unt.edu/ark:/67531/metadc849686/
Biodiversity and Genetic Structure of Benthic Macroinvertebrates along an Altitudinal Gradient: A Comparison of the Windhond and Róbalo River Communities on Navarino Island, Chile
Altitudinal gradients in Sub-Antarctic freshwater systems present unique opportunities to study the effect of distinct environmental gradients on benthic macroinvertebrate community composition and dispersal. This study investigates patterns in biodiversity, dispersal and population genetic structure of benthic macroinvertebrate fauna across an altitudinal gradient between two watersheds on Navarino Island in southern Chile. Patterns in diversity, density, evenness and functional feeding groups were not significantly different across the altitudinal gradient in both the Windhond and Róbalo Rivers. Taxa richness in both rivers generally increased from the headwaters of the river to the mouth, and functional feeding group patterns were consistent with the predictions of the River Continuum Concept. Population genetic structure and gene flow was investigated by sampling the mitochondrial cytochrome oxidase I gene in two invertebrate species with different dispersal strategies. Hyalella simplex (Amphipoda) is an obligate aquatic species, and Meridialaris chiloeense (Ephemeroptera) is an aquatic larvae and a terrestrial winged adult. Contrasting patterns of population genetic structure were observed. Results for Hyalella simplex indicate significant differentiation in genetic structure in the Amphipod populations between watersheds and lower genetic diversity in the Róbalo River samples, which may be a result of instream dispersal barriers. Meridialaris chiloeense exhibited weak population structure but higher genetic diversity, which suggests this species is able to disperse widely as a winged adult. digital.library.unt.edu/ark:/67531/metadc849782/
Caffeine’s effects on pausing during alternating work requirements.
There is a significant body of literature stating that caffeine is the most widely consumed drug in the world, yet its effects on operant behavior are little understood. Some of the current research on caffeine suggests that it may play a role in altering motivational states related to transitions between previous and upcoming work requirements. The purpose of the current study was to examine the effects of caffeine on postreinforcement pausing during transitions between small and large fixed ratio rudiments. Eight rats were exposed to five doses of caffeine and and a two-component multiple schedule. We found that caffeine does systematically alter the length of pausing during transitions between fixed ratio requirements, however the magnitude of the effect may be dependent on the baseline rate of responding. digital.library.unt.edu/ark:/67531/metadc849709/
Carnaval, grotesco y dialogismo en las zarzuelas de Pablo Sorozábal
In the present study, the three principal theories of Russian theorist Mikhail Bakhtin--the carnavalesque, grotesque, and dialogical--are applied to the musical-theatre genre of the Spanish zarzuela. The focus of the study centers on the works of composer Pablo Sorozábal and the various librettists who collaborated with him, among them the renowned literary author Pío Baroja. Within this study, zarzuela is first analyzed on its own in terms of the academic debate surrounding the genre and its importance in terms of both literary and musical criticism. After establishing the particular capacity of the zarzuela to make important cultural contributions, the central theoretical framework of the thesis is established via Bakhtinian theory, and several links are drawn between this theory and the genre of the zarzuela, which is shown to be a body of work often capable of conveying subversive messages, both cultural and sociopolitical. With this critical lens, then, the specific sociopolitical context of Spain between 1931-1942 is analyzed and described in order to illustrate the various extratextual and intertextual elements at play in Sorozábal's zarzuelas. The three works ultimately studied are Katiuska (1931), Adiós a la bohemia (1933), and Black, el payaso (1942). By way of highlighting the Bakhtinian characteristics at play in these three zarzuelas, the composer's intention to challenge and criticize Spain's sociopolitical reality, including Francoist dictatorship, is revealed, illustrating the capacity of the zarzuela to challenge and transgress existing norms--an aspect that many critics have failed to recognize in the genre up to the present day. digital.library.unt.edu/ark:/67531/metadc849749/
Causes of the Jewish Diaspora Revolt in Alexandria: Regional Uprisings from the Margins of Greco-Roman Society
This thesis examines the progression from relatively peaceful relations between Alexandrians and Jews under the Ptolemies to the Diaspora Revolt under the Romans. A close analysis of the literature evidences that the transition from Ptolemaic to Roman Alexandria had critical effects on Jewish status in the Diaspora. One of the most far reaching consequences of the shift from the Ptolemies to Romans was forcing the Alexandrians to participate in the struggle for imperial patronage. Alexandrian involvement introduced a new element to the ongoing conflict among Egypt’s Jews and native Egyptians. The Alexandrian citizens consciously cut back privileges the Jews previously enjoyed under the Ptolemies and sought to block the Jews from advancing within the Roman system. Soon the Jews were confronted with rhetoric slandering their civility and culture. Faced with a choice, many Jews forsook Judaism and their traditions for more upwardly mobile life. After the outbreak of the First Jewish War Jewish life took a turn for the worse. Many Jews found themselves in a system that classified them according to their heritage and ancestry, limiting advancement even for apostates. With the resulting Jewish tax (fiscus Judaicus) Jews were becoming more economically and socially marginalized. The Alexandrian Jews were a literate society in their own right, and sought to reverse their diminishing prestige with a rhetoric of their own. This thesis analyzes Jewish writings and pagan writings about the Jews, which evidences their changing socio-political position in Greco-Roman society. Increasingly the Jews wrote with an urgent rhetoric in attempts to persuade their fellow Jews to remain loyal to Judaism and to seek their rights within the construct of the Roman system. Meanwhile, tensions between their community and the Alexandrian community grew. In less than 100 years, from 30 CE to 117 CE, the Alexandrians attacked the Jewish community on at least three occasions. Despite the advice of the most Hellenized elites, the Jews did not sit idly by, but instead sought to disrupt Alexandrian meetings, anti-Jewish theater productions, and appealed to Rome. In the year 115 CE, tensions reached a high. Facing three years of violent attacks against their community, Alexandrian Jews responded to Jewish uprisings in Cyrene and Egypt with an uprising of their own. Really a series of revolts, historians have termed these events simply “the Diaspora Revolt.” digital.library.unt.edu/ark:/67531/metadc849731/
Characterization of post-plasma etch residues and plasma induced damage evaluation on patterned porous low-k dielectrics using MIR-IR spectroscopy.
As the miniaturization of functional devices in integrated circuit (IC) continues to scale down to sub-nanometer size, the process complexity increases and makes materials characterization difficult. One of our research effort demonstrates the development and application of novel Multiple Internal Reflection Infrared Spectroscopy (MIR-IR) as a sensitive (sub-5 nm) metrology tool to provide precise chemical bonding information that can effectively guide through the development of more efficient process control. In this work, we investigated the chemical bonding structure of thin fluorocarbon polymer films deposited on low-k dielectric nanostructures, using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Complemented by functional group specific chemical derivatization reactions, fluorocarbon film was established to contain fluorinated alkenes and carbonyl moieties embedded in a highly cross-linked, branched fluorocarbon structure and a model bonding structure was proposed for the first time. In addition, plasma induced damage to high aspect ratio trench low-k structures especially on the trench sidewalls was evaluated both qualitatively and quantitatively. Damage from different plasma processing was correlated with Si-OH formation and breakage of Si-CH3 bonds with increase in C=O functionality. In another endeavor, TiN hard mask defect formation after fluorocarbon plasma etch was characterized and investigated. Finding suggest the presence of water soluble amines that could possibly trigger the formation of TiN surface defect. An effective post etch treatment (PET) methods were applied for etch residue defect removal/suppression. digital.library.unt.edu/ark:/67531/metadc849694/
Charged Particle Transport and Confinement Along Null Magnetic Curves and in Various Other Nonuniform Field Configurations for Applications in Antihydrogen Production
Comparisons between measurements of the ground-state hyperfine structure and gravitational acceleration of hydrogen and antihydrogen could provide a test of fundamental physical theories such as CPT (charge conjugation, parity, time-reversal) and gravitational symmetries. Currently, antihydrogen traps are based on Malmberg-Penning traps. The number of antiprotons in Malmberg-Penning traps with sufficiently low energy to be suitable for trappable antihydrogen production may be reduced by the electrostatic space charge of the positrons and/or collisions among antiprotons. Alternative trap designs may be needed for future antihydrogen experiments. A computational tool is developed to simulate charged particle motion in customizable magnetic fields generated by combinations of current loops and current lines. The tool is used to examine charged particle confinement in two systems consisting of dual, levitated current loops. The loops are coaxial and arranged to produce a magnetic null curve. Conditions leading to confinement in the system are quantified and confinement modes near the null curve and encircling one or both loops are identified. Furthermore, the tool is used to examine and quantify charged particle motion parallel to the null curve in the large radius limit of the dual, levitated current loops. An alternative to new trap designs is to identify the effects of the positron space in existing traps and to find modes of operation where the space charge is beneficial. Techniques are developed to apply the Boltzmann density relation along curved magnetic field lines. Equilibrium electrostatic potential profiles for a positron plasma are computed by solving Poisson's equation using a finite-difference method. Equilibria are computed in a model Penning trap with an axially varying magnetic field. Also, equilibria are computed for a positron plasma in a model of the ALPHA trap. Electric potential wells are found to form self-consistently. The technique is expanded to compute equilibria for a two-species plasma with an antiproton plasma confined by the positron space charge. The two-species equilibria are used to estimate timescales associated with three-body recombination, losses due to collisions between antiprotons, and temperature equilibration. An equilibrium where the three-body recombination rate is the smallest is identified. digital.library.unt.edu/ark:/67531/metadc849779/
Child Centered Play Therapy with Children Exhibiting Aggressive Behaviors
Aggressive behaviors in childhood currently serve as the leading cause of counselor referrals within the United States. Children exhibiting maladaptive aggressive symptomology are at an increased risk for highly externalized and problematic behaviors across the lifespan. Emotional self-regulation and empathy are two constructs currently believed to be closely related to aggression, but a lack of research exploring these variables currently exists in the counseling literature. In this study I examined the effect of child-centered play therapy (CCPT), is a manualized, developmentally responsive, and nondirective intervention, on these variables. Participants were 71 students from four Title 1 elementary schools in the southwest U.S. referred by teachers for aggressive behavior (12 females, 59 males; age range 5-10 years with mean age 6.28. The sample consisted of 52.1% (n = 37) children identified as African American, 21.1% (n = 15) as Latina/Latino, 19.7% (n = 14) as Caucasian, and 7% as multiracial (n = 5). Participants were randomly assigned to 8 weeks of a twice-weekly CCPT experimental group (n = 36) or a waitlist control group (n = 35). Results of descriptive discriminant analyses (DDA) of the Social Emotional Assets and Resilience Scale and the Children’s Aggression Scale scores revealed that parents perceived children’s group membership in CCPT as significant and reasonably predictive of improvement in children’s aggression, self-regulation, and empathy. However, teachers did not perceive a statistically significant difference between the two groups with respect to these variables. These results suggest the relevancy of CCPT for parents in providing children with a developmentally responsive intervention to reduce aggressive behaviors and support their healthy development. digital.library.unt.edu/ark:/67531/metadc849767/
A Clinical Case Study of Rumination and Emesis in an Adult Male with Intellectual Disability
An evaluation of a series of interventions was conducted for an individual who engaged in life-threatening rumination and emesis. There is substantial research indicating that the delivery of peanut butter (Barton & Barton, 1985; Greene, Johnston, Rossi, Racal, Winston, & Barron, 1991) and/or chopped bread following meals (Thibadeau, Blew, Reedy, & Luiselli, 1999), chewing gum (Rhine & Tarbox, 2009), and satiation procedures (Dudley, Johnston, & Barnes, 2002; Lyons, Rue, Luiselli, & DiGennario, 2007; Rast, Johnston, Drum, & Conrin, 1981) can be effective treatments for rumination. In the current case, each of these interventions was found to be either ineffective or contraindicated based on the participant's fragile health status. Previous literature has shown that liquid delivery can affect rates of rumination in some clients (Barton & Barton, 1985,; Heering, Wilder, & Ladd, 2003). We examined how liquid affected the rate of rumination during and after meals. Based on the individual's medical condition, oral nutrition and fluids were discontinued indefinitely and a gastronomy-jejunostomy tube was used for nutrition. All rumination ceased when fluids and nutrition were delivered via the jejunostomy tube. Finally, a fluid analysis procedure was implemented in which the participant received small amounts of fluid while NPO. Color and flavor were manipulated systematically, and results suggested that flavor impacted the rate of rumination. digital.library.unt.edu/ark:/67531/metadc849785/
Comment peut-on être Persane ou Péruvienne ? On le devient.
Cette analyse littéraire examine les parallèles entre les deux romans Lettres persanes de Montesquieu (1721) et Lettres d'une Péruvienne de Françoise de Graffigny (1747) en se concentrant sur le sort des femmes et leur rébellion contre la claustration. Leurs révoltes transformatrices révèlent une volonté qui refuse et puis transcende les barreaux de leur captivité pour vivre librement. La philosophie de Simone de Beauvoir (1908-1986) personnifie leurs luttes pour devenir et exister, ce qui se traduit par leur capacité de dévoiler leur vraie nature. Elles se battent contre le néant de leurs existences où elles ne peuvent que succomber aux contraintes imposées. Elles se battent pour se définir et pour devenir. Cependant, c'est Graffigny qui nous offre une réponse plus proto-féministe dépassant les paramètres masculins de la société. Son livre répond directement aux Lettres persanes pour créer une nouvelle femme iconoclaste qui transcende les barrières de la société pour se réinventer. digital.library.unt.edu/ark:/67531/metadc849679/
Commercial Diplomacy: The Berlin-Baghdad Railway and Its Peaceful Effects on Pre-World War I Anglo-German Relations
Slated as an economic outlet for Germany, the Baghdad Railway was designed to funnel political influence into the strategically viable regions of the Near East. The Railway was also designed to enrich Germany's coffers with natural resources with natural resources and trade with the Ottomans, their subjects, and their port cities... Over time, the Railway became the only significant route for Germany to reach its "place in the sun," and what began as an international enterprise escalated into a bid for diplomatic influence in the waning Ottoman Empire. digital.library.unt.edu/ark:/67531/metadc849612/
Comparative study of perceived barriers to faculty participation in distance education at a four-year university
Bailey, Elizabeth, Comparative study of perceived barriers to faculty participation in distance education at a four-year university. Doctor of Philosophy (Education), December 2015, 103 pp., 21 tables, references. The purpose of this Bailey study was to identify perceived barriers of faculty participation in distance education courses in a four-year university and identify the differences in perceived barriers between the Hebert 2003 study and this Bailey study. The literature review covers numerous studies and articles written within the last 10 years that are related to a variety of barriers perceived by faculty and administrators. There were no statistically significant relationships found between faculty demographics including gender, age, position at the university, tenure status, and number of years faculty have taught in post-secondary education. There were no statistically significant relationships found between the top administrator-ranked motivators and corresponding faculty-ranked motivators, nor between the top administrator-ranked inhibitors and the corresponding faculty-ranked inhibitors. Out of the top four non-participating, faculty-ranked barriers, three were found to have statistically significant relationships with the corresponding administrator-ranked barriers. Statistically significant relationships were found between the faculty-ranked motivators and corresponding administrator identified motivators and between the top ranked barriers identified by non-participating faculty and administrators in Hebert’s study compared to non-participating faculty-ranked and administrator-ranked barriers identified in this study. digital.library.unt.edu/ark:/67531/metadc849738/
Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism
Reinforcer assessments have largely relied on the use of progressive ratio (PR) schedules to identify stimuli that function as reinforcers. PR schedules evaluate the reinforcing efficacy of a stimulus by measuring the number of responses produced in order to access a stimulus as the number of required responses increases. The current evaluation extends the literature on reinforcer assessments by measuring responding under a progressive force (PF) schedule, in addition to progressive ratio requirements. We compared responding under PR and PF schedules with two children with autism using a multielement design embedded within a reversal experimental design. Results were mixed and implications for further development of reinforcer assessment methods (particularly PF schedules) are discussed. digital.library.unt.edu/ark:/67531/metadc849638/
A Comparison of Methods for Sight-Reading Utilizing Collegiate Saxophonists
The ability to sight-read well is held as a highly regarded and important skill in music performance and education. Over the past 90 years, researchers have investigated several aspects of music sight-reading, especially those attributes possessed by skilled sight-readers. A significant and recurrent finding from this body of research is the relationship between sight-reading and rhythm recognition. Though these studies have found positive effects and correlations between rhythm recognition and sight-reading, they have been limited and indirect. The aim of this dissertation was to investigate the effects of (a) practicing rhythms on a single pitch and (b) practicing rhythms with full-range scales and their direct effects on sight-reading ability in saxophonists at the college level. The primary objective in this research was to determine if one method was more effective than another in developing sight-reading skills. The participants (N = 74) consisted of college students who were enrolled in saxophone lessons at a university in the southwestern United States. Participants were administered a sight-reading pre-test at the beginning of an 8-week treatment period. After pre-testing, students were blocked into two groups. The first treatment group was assigned to practice rhythms on a single pitch and the second treatment group was assigned to practice rhythms combined with full-range major scales. After the treatment period, participants were administered a sight-reading post-test. A 2-way mixed ANOVA was used to determine if there were differences between treatment groups, differences from pre-test to post-test, and if there was a significant interaction between treatment and time. There was no significant difference between treatment groups, F (1, 72) = .035, p = .852, partial η2 = .000028. There was a significant effect for time, indicating that both treatment groups improved from pre-to post test, F (1, 72) = 83.499, p < .001, partial η2 = .537. There was no significant interaction between treatment and time, F (1, 72) = .322, p = .572, partial η2 = .004. digital.library.unt.edu/ark:/67531/metadc849708/
A comparison of Petar Christoskov’s Op. 1 and Op. 24 Caprices for Solo Violin: The effect of the changing Bulgarian political climate on his compositional style.
Bulgaria, though a fairly small Eastern European country, boasts an ancient history of folk traditions and music; however, very few notated works exist due to the people's primitive lifestyle throughout Bulgaria's history. Singing and dancing as well as creating instruments from wood and animal skin were considered an integral part of everyday life, equal to cooking, sewing, herding, or farming; in fact, one almost always accompanied the other. Thus, more than 1500 years of folklore was orally passed on and preserved generation after generation; however, nothing was notated until only very recently when Bulgarians realized the cultural and national value of their history. After the liberation from Ottoman Rule (1453-1877) a nationalist movement spread throughout the Balkan countries, which resulted in the emergence of Bulgarian composers. Music and songs from the local folk traditions evolved, developed, and - with notation - became the foundation for the vocal and instrumental music of the so-called first generation of Bulgarian composers. Around the turn of the century, many Bulgarian artists and musicians traveled to Western Europe (mostly Austria, Germany, and Russia) and upon their return, their artistic output created an original mixture of Bulgarian national folk with influences from Western classical music. After World War II, Bulgaria became one of the countries governed by the Communist regime, which restricted all travel to and contact with the West, including cultural influences from the West. Gradually, as the Communist regime became less controlling until it dissolved completely in 1989, restrictions on music and culture started to lift. Petar Christoskov (1917-2006), considered part of the second generation of Bulgarian composers, began his compositional career immediately after returning from Germany to a communist-ruled Bulgaria. His first opus was the set of 12 Caprices for Solo Violin (1953, formerly known as Concert Etudes in Folk Style); they have a fairly simple compositional style but are full of elements from the Bulgarian folk tradition. Some of these caprices, along with other works from the beginning of Christoskov's compositional career, were commissioned by the nationalist government and/or were required repertoire at national music competitions. Nearly thirty years after the first set of caprices, Christoskov composed another set: 24 Caprices for Solo Violin, Op. 24 (1978-9). These later works also contain many Bulgarian folk characteristics, but their compositional style is much more abstract, atonal, and complex - more “mainstream Western.” The goal of this document is to compare and contrast the two sets of Caprices for Solo Violin, Op. 1 and Op. 24, by investigating the development of Petar Christoskov's compositional style. I will argue that the constantly-changing political systems in twentieth-century Bulgaria had a direct impact on the composer's artistic output. After a historical overview of Bulgaria's music and political background, the two sets of caprices will be compared and contrasted by focusing on technical, musical, and sociological similarities and differences. In order to illustrate these similarities and differences, three caprices from each set will be selected and analyzed, as well as compared and contrasted with each other. The second part of the document will discuss the negative influence of the political climate on music and printing, with a focus on the difficulties of preserving Bulgarian culture itself. This research has the additional purpose of serving as scholarly support for a future project: as a personal contribution to the circulation and preservation of Bulgarian music, I intend to produce a new violin edition of Petar Christoskov's caprices as well as complete the arrangements for viola. digital.library.unt.edu/ark:/67531/metadc849741/
Compositional approaches within new media paradigms.
"Compositional Approaches to New Media Paradigms" is the discursive accompaniment to the original composition BoMoH, (a new media chamber opera. A variety of new media concepts and practices are discussed in relation to their use as a contemporary compositional methodology for computer musicians and digital content producers. This paper aligns relevant discourse with a variety of concepts as they influence and affect the compositional process. This paper does not propose a new working method; rather it draws attention to a contemporary interdisciplinary practice that facilitates new possibilities for engagement and aesthetics in digital art/music. Finally, in demonstrating a selection of the design principals, from a variety of new media theories of interest, in compositional structure and concept, it is my hope to provide composers and computer musicians with a tested resource that will function as a helpful set of working guidelines for producing new media enabled art, sonic or otherwise. digital.library.unt.edu/ark:/67531/metadc849618/
The Concerto for Bassoon by Andrzej Panufnik: Religion, Liberation, and Postmodernism
The Concerto for Bassoon by Andrzej Panufnik is a valuable addition to bassoon literature. It provides a rare opportunity for the bassoon soloist to perform a piece which is strongly programmatic. The purpose of this document is to examine the historical and theoretical context of the Concerto for Bassoon with special emphasis drawn to Panufnik's understanding of religion in connection with Polish national identity and the national struggle for democratic independence galvanized by the murder of Father Jerzy Popieluszko in 1984. Panufnik's relationship with the Polish communist regime, both prior to and after his 1954 defection to England, is explored at length. Each of these aspects informed Panufnik's compositional approach and the expressive qualities inherent in the Concerto for Bassoon. The Concerto for Bassoon was commissioned by the Polanki Society of Milwaukee, Wisconsin and was premiered by the Milwaukee Chamber Players, with Robert Thompson as the soloist. While Panufnik intended the piece to serve as a protest against the repression of the Soviet government in Poland, the U. S. context of the commission and premiere is also examined. Additionally, the original manuscript and subsequent piano reduction are compared. Although the Concerto for Bassoon has been subject to formal analysis by several scholars, discussion of the piece is generally contained within a larger discussion of several other compositions, and a comprehensive analysis of the piece has not yet been presented. This document contains a thorough formal analysis of all movements, as well as analysis of Panufnik's compositional style within the context of serialism, postmodernism, and the new Polish school of composition. The Concerto fro Bassoon features several devices common to Panufnik's larger opus, including the se of a common three-note cell, strong contrasts between section and movements, and symmetrical patterns of transposition, metric alteration, dynamic alteration, and registral expansion. digital.library.unt.edu/ark:/67531/metadc849689/
The Contemporary Bassoonist: Music for Interactive Electroacoustics and Bassoon
As the bassoon has evolved over time, the music written for the instrument has evolved around it, and was many times the catalyst for its evolution. Bassoon music of the seventeenth through early twentieth centuries has defined much of the curricula for bassoon studies, and has established how we consider and experience the bassoon. We experience, write, and consume music in vastly different ways than just a generation ago. Humans use technology for the most basic of tasks. Composers are using the technology of our generation to compose music that is a reflection of our time. This is a significant aspect of art music today, and bassoonists are barely participating in the creation of this new repertoire. Performance practice often considers only the musical score; interactive electronic music regularly goes beyond that. The combination of technological challenges and inexperience can make approaching electroacoustic music a daunting and inaccessible type of music for bassoonists. These issues require a different language to the performance practice: one that addresses music, amplification, computer software, hardware, the collaboration between performer and technology, and often the performer and composer. The author discusses problems that performers face when rehearsing and performing interactive electroacoustic works for bassoon, and offers some solutions. digital.library.unt.edu/ark:/67531/metadc849603/
Continuous Combinatorics of a Lattice Graph in the Cantor Space
We present a novel theorem of Borel Combinatorics that sheds light on the types of continuous functions that can be defined on the Cantor space. We specifically consider the part X=F(2ᴳ) from the Cantor space, where the group G is the additive group of integer pairs ℤ². That is, X is the set of aperiodic {0,1} labelings of the two-dimensional infinite lattice graph. We give X the Bernoulli shift action, and this action induces a graph on X in which each connected component is again a two-dimensional lattice graph. It is folklore that no continuous (indeed, Borel) function provides a two-coloring of the graph on X, despite the fact that any finite subgraph of X is bipartite. Our main result offers a much more complete analysis of continuous functions on this space. We construct a countable collection of finite graphs, each consisting of twelve "tiles", such that for any property P (such as "two-coloring") that is locally recognizable in the proper sense, a continuous function with property P exists on X if and only if a function with a corresponding property P' exists on one of the graphs in the collection. We present the theorem, and give several applications. digital.library.unt.edu/ark:/67531/metadc849680/
The Controversial Identity of Flamenco Jazz: A New Historical and Analytical Approach
There are certain recordings by important artists such as Lionel Hampton, Miles Davis, John Coltrane, Pedro Iturralde, Chick Corea, and Paco de Lucía, among others, that have been associated with the label flamenco jazz. This label is entering jazz discourse, and it needs to be better understood in order to clarify its history, its identity, and its impact on recent developments in flamenco that are labeled nuevo flamenco. There is a lack of agreement in the existent literature on flamenco jazz on the evaluation of these recordings and these artists' achievements and contributions to this field. These writings encompass authors from different backgrounds: journalists, critics, and musicologists, who have approached their analysis of the recordings from different perspectives. The differences in professional backgrounds, approaches, and purpose of the writings of these authors has resulted in controversy about this label. Therefore, the flamenco jazz scholarly conversation needs more objective writings from an analytical point of view. This historiographical study presents a more comprehensive evaluation of flamenco jazz by discussing selected recordings using analytical tools from jazz studies. These analytical arguments clarify the aesthetics of flamenco jazz and the artistic processes that these artists went through when combining musical elements from flamenco and jazz, which in some cases are described as creative misreading. In this century of cultural globalization, where jazz has become a diverse expression of world music because of its capacity to absorb traits from other musical practices, this study can be a resource for international jazz musicians who are seeking to combine jazz with their musical cultural heritage. digital.library.unt.edu/ark:/67531/metadc849724/
Conversational Use of Photographic Images on Facebook: Modeling Visual Thinking on Social Media
Modeling the "thick description" of photographs began at the intersection of personal and institutional descriptions. Comparing institutional descriptions of particular photos that were also used in personal online conversations was the initial phase. Analyzing conversations that started with a photographic image from the collection of the Library of Congress (LC) or the collection of the Manchester Historic Association (MHA) provided insights into how cultural heritage institutions could enrich the description of photographs by using informal descriptions such as those applied by Facebook users. Taking photos of family members, friends, places, and interesting objects is something people do often in their daily lives. Some photographic images are stored, and some are shared with others in gatherings, occasions, and holidays. Face-to-face conversations about remembering some of the details of photographs and the event they record are themselves rarely recorded. Digital cameras make it easy to share personal photos in Web conversations and to duplicate old photos and share them on the Internet. The World Wide Web even makes it simple to insert images from cultural heritage institutions in order to enhance conversations. Images have been used as tokens within conversations along with the sharing of information and background knowledge about them. The recorded knowledge from conversations using photographic images on Social Media (SM) has resulted in a repository of rich descriptions of photographs that often include information of a type that does not result from standard archival practices. Closed group conversations on Facebook among members of a community of interest/practice often involve the use of photographs to start conversations, convey details, and initiate story-telling about objets, events, and people. Modeling of the conversational use of photographic images on SM developed from the exploratory analyses of the historical photographic images of the Manchester, NH group on Facebook. The model was influenced by the typical model of Representation by Agency from O'Connor in O'Connor, Kearns, and Anderson Doing Things with Information: Beyond Indexing and Abstracting, by considerations of how people make and use photographs, and by the notion of functionality from Patrick Wilson's Public Knowledge, Private Ignorance: Toward a Library and Information Policy. The model offers paths for thickening the descriptions of photographs in archives and for enriching the use of photographs on social media. digital.library.unt.edu/ark:/67531/metadc849631/
Correspondence between Multiple-Respondent Anecdotal Assessments and Functional Analysis: Analyses of Rank-Order, Magnitude-of-Difference, and Overall Outcomes
We administered the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF) to five raters and compared the results with functional analysis outcomes for 12 cases in which agreement was obtained for at least four out of five raters on either anecdotal assessment. The scores for functional categories on the MAS and QABF were ranked by averaging the scores for the raters who agreed on the primary maintaining variable. Functional analysis results were ranked by examining average responding across all conditions. A comparison showed correspondence between the highest category and the highest functional analysis condition for 10 out of 11 cases for the MAS and all 10 cases for the QABF. Correspondence for the category and condition ranked second was found for 2 out of 11 cases for the MAS and 2 out of 10 cases for the QABF. The magnitude of difference between categories on the MAS/QABF did not appear to predict the amount of difference in responding in the corresponding functional analyses. digital.library.unt.edu/ark:/67531/metadc849776/
Cross-cultural adjustment of self-initiated expatriates and individual work performance.
Globalization in the past few decades has been marked by increased mobility of highly skilled workers from one country to another. Even though self-initiated expatriation is a widespread phenomenon, it is a relatively under-researched phenomenon in the academic literature, especially in an organizational context. Existing literature shows that not all individuals are equally suited to embark on a new life in another country, and self-initiated expatriates (SIEs) could be particularly susceptible to failure since they have no support from a home organization. This study was designed to investigate the experiences of self-initiated professional expatriates and the effect it had on their work performance. The purpose was to understand how their organizational and social experience affected their cross-cultural adjustment process and in turn affected their individual work performance. The researcher used a qualitative method using semi-structured interviews, observations, and documents with ten self-initiated expatriates. This study contributed to the expanding literature on the experiences of self-initiated expatriates, specifically how different support systems affected cross-cultural adjustment and individual work performance. digital.library.unt.edu/ark:/67531/metadc849667/
Customizable Modality Pathway Learning Design: Exploring Personalized Learning Choices through a Lens of Self-Regulated Learning
Open online courses provide a unique opportunity to examine learner preferences in an environment that removes several pressures associated with traditional learning. This mixed methods study sought to examine the pathways that learners will create for themselves when given the choice between an instructor-directed modality and learner-directed modality. Study participants were first examined based on their levels of self-regulated learning. Follow-up qualitative interviews were conducted to examine the choices that participants made, the impact of the course design on those choices, and what role self-regulation played in the process. The resulting analysis revealed that participants desired an overall learning experience that was tailored to personal learning preferences, but that technical and design limitations can create barriers in the learning experience. The results from this research can help shape future instructional design efforts that wish to increase learner agency and choice in the educational process. digital.library.unt.edu/ark:/67531/metadc849703/
"Deborah": The Creation of a Chamber Oratorio in One Act
In comparing oratorio traits across history, three aspects of oratorio were found to be particularly applicable to the creation of "Deborah: A Chamber Oratorio in One Act." These aspects were: the selection of topic and the creation or adaptation of text; the differences between recitative and aria, in form and function; and the level of stylistic diversity within a given work. digital.library.unt.edu/ark:/67531/metadc849726/
Determinants of Principal Pay in the State of Texas
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 be addressed in order to learn more about their effects and make sound public policies. The paper utilized a spatial regression approach to examine the determinants of principal salary using data from the local, state, and national data sources. Principal salaries are viewed from several lenses in this study by considering effective outcomes of pay defined by actual salaries and market considerations for pay as defined by community, organizational, and human capital variables. Literature from the private sector as well as from the public school setting was used as a theoretical underpinning for the hypotheses set forth in this study. Because of the chosen research approach, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further. The paper includes implications for educational policy development related to pay for contribution, rather than pay based on tenure, experience, or district wealth. The research also fulfils an identified policy need to study how principal salaries are determined. digital.library.unt.edu/ark:/67531/metadc849764/

Direct Inject Mass Spectrometry for Illicit Chemistry Detection and Characterization
The field of direct inject mass spectrometry includes a massive host of ambient ionization techniques that are especially useful for forensic analysts. Whether the sample is trace amounts of drugs or explosives or bulk amounts of synthetic drugs from a clandestine laboratory, the analysis of forensic evidence requires minimal sample preparation, evidence preservation, and high sensitivity. Direct inject mass spectrometry techniques can rarely provide all of these. Direct analyte-probed nanoextraction coupled to nanospray ionization mass spectrometry, however, is certainly capable of achieving these goals. As a multifaceted tool developed in the Verbeck laboratory, many forensic applications have since been investigated (trace drug and explosives analysis). Direct inject mass spectrometry can also be easily coupled to assays to obtain additional information about the analytes in question. By performing a parallel artificial membrane assay or a cell membrane stationary phase extraction prior to direct infusion of the sample, membrane permeability data and receptor activity data can be obtained in addition to the mass spectral data that was already being collected. This is particularly useful for characterizing illicit drugs and their analogues for a biologically relevant way to schedule new psychoactive substances. digital.library.unt.edu/ark:/67531/metadc849747/
Do Re Mi? Yes! Using Music and Visual Arts to Promote Thai Children's English Vocabulary Development
This research examines the efficacy, if any, of the Music and Visual Arts (MVA) program in improving the English vocabulary development of first grade Thai students. The researcher developed the Vocabulary Recognition Assessment (VRA) as a measure of English vocabulary development. It employs the accuracy and rapidity method of word recognition as a measurement of English language development in Thai children. Forty first grade Thai students in a Bangkok elementary school participated in the study. Participants were divided equally between an experimental group and a control group. During a nine-week period, students in the experimental group were instructed with the MVA strategy, while students in the control group were taught with the Visual Arts (VA) strategy. Paired sample t-test, ANOVA, and ANCOVA were used to analyze data from the VRA, to compare the pre-test and the post-test in terms of accuracy scores and rapidity scores of the control group and the experimental group. Data revealed that students instructed with the MVA strategy improved their English vocabulary development in terms of accuracy of word recognition significantly more than students taught English using the VA strategy. No significant difference was found between the MVA strategy and the VA strategy in terms of rapidity of word recognition. The MVA strategy could be a useful strategy for Thai early childhood teachers to use in helping Thai children learn English vocabulary. digital.library.unt.edu/ark:/67531/metadc849681/
Do You Know the Storm? The Forgotten Lieder of Franz Schreker
Franz Schreker (1878-1934) was a Jewish-Austrian composer of great success during the first decades of the twentieth century. Schreker’s reputation diminished after 1933 when Hitler came to power and, in 1938, his compositions were labeled Entartete Musik (“degenerate music”) by the Nazis in a public display in Düsseldorf. The Third Reich and post-war Germany saw Schreker as a decadent outcast, misunderstanding his unique style that combined elements of romanticism, expressionism, impressionism, symbolism, and atonality. This study of Schreker’s Lieder will pursue two goals. First, it will analyze the Mutterlieder (before 1898), the Fünf Gesänge (1909), and the first piece from Vom ewigen Leben (1923) stylistically. Schreker composed nearly four dozen Lieder, incorporating a wide range of styles and ideas. By studying and performing these songs written at various points in his career (including early songs, songs written after he met Schoenberg, and his last songs during the height of his fame), I hope to develop a clearer understanding of how Schreker synthesized the many cultural forces and artistic movements that seem to have influenced his compositional style. Second, this study will consider the sociopolitical circumstances that fueled the disintegration of his reputation. This disintegration occurred not just during the Third Reich, but also afterwards, notably in an often discussed essay by Theodor Adorno. Only in the last thirty years have scholarly voices critical of such rejections of Schreker emerged. My ultimate goal, then, is to join this reevaluation, studying and contextualizing this repertory to develop a new understanding of an oft-neglected chapter in the history of the German Lied. digital.library.unt.edu/ark:/67531/metadc849748/
The Effects of a Parent Training Program that is Responsive to Current Repertoire and Affect
Social deficits are one of the defining symptoms of autism spectrum disorder and affect a child’s ability to build relationships with others. These deficits put children with autism at a disadvantage when most of their world is focused on building connections with others – family, friendships, and community ties. Sunny Starts, a service-learning project, was created to specifically meet the needs of families with young toddlers with autism. The primary focus of Sunny Starts is to enhance the quality of the parent-child relationship by teaching parents a basic teaching interaction and to arrange the child’s environment in ways that are mutually reinforcing. The purpose of this experiment is to study the effects of the Sunny Starts DANCE training package, a responsive parent training program, on three levels of parent and child behaviors: 1) teaching episodes, 2) turn taking, social attending, vocal requests, and 3) synchronous engagement. Participants included two parent-child dyads. Parent training included 5-minute video assessments, video review, descriptions, rationales, modeling, practice, and feedback. The effects of the parent training were evaluated using a concurrent multiple baseline across participants. Results indicate parent teaching episodes and child behaviors (turn taking, social attending, and verbal requests) increased during the intervention phase. The duration of parent-child synchronous engagement maintained at high levels and slightly increased. digital.library.unt.edu/ark:/67531/metadc849784/
The Effects of Neonicotinoid Exposure on Embryonic Development and Organ Mass in Northern Bobwhite Quail
Since their emergence in the early 1990s, neonicotinoid use has increased exponentially to make them the world's most prevalent insecticides. Although there is considerable research concerning the lethality of neonicotinoids, their sub-lethal and developmental effects are still being explored, especially with regards to non-mammalian species. The goal of this research was to investigate the effects of the neonicotinoid imidacloprid on the morphological and physiological development of northern bobwhite quail (Colinus virginianus). Bobwhite eggs (n = 650) were injected with imidacloprid concentrations of 0 (sham), 10, 50, 100 and 150 grams per kilogram of egg mass, which was administered at day 0 (pre-incubation), 3, 6, 9, or 12 of growth. Embryos were dissected on day 19 when they were weighed, staged, and examined for any overt structural deformities. Embryonic heart, liver, lungs and kidneys were also weighed and preserved for future use. Treated embryos exhibited increased frequency of severely deformed beaks and legs, as well as larger hearts and smaller lungs at the higher dosing concentrations. Some impacts are more pronounced in specific dosing periods, implying that there may be critical windows of development when embryos are highly susceptible to neonicotinoid exposure. This investigation suggests that imidacloprid could play a significant role in chick survival and declining quail populations in treated regions of the country. digital.library.unt.edu/ark:/67531/metadc849707/
An Empirical Study of How Novice Programmers Use the Web
Students often use the web as a source of help for problems that they encounter on programming assignments.In this work, we seek to understand how students use the web to search for help on their assignments.We used a mixed methods approach with 344 students who complete a survey and 41 students who participate in a focus group meetings and helped in recording data about their search habits.The survey reveals data about student reported search habits while the focus group uses a web browser plug-in to record actual search patterns.We examine the results collectively and as broken down by class year.Survey results show that at least 2/3 of the students from each class year rely on search engines to locate resources for help with their programming bugs in at least half of their assignments;search habits vary by class year;and the value of different types of resources such as tutorials and forums varies by class year.Focus group results exposes the high frequency web sites used by the students in solving their programming assignments. digital.library.unt.edu/ark:/67531/metadc849754/
Evaluating the Effectiveness of a Competency-Based Training Package to Teach Behavior Management Skills to Direct Support Staff
Cooper, Heron and Heward define maintenance as the extent to which a learner continues to perform a target behavior after the intervention has been terminated. Testing for maintenance allows the trainer to see if gains were sustained following the termination of a treatment program. In addition, once it is shown that a learner's skills have remained in the repertoire, assessment of generalization is possible. Previous literature in behavior skills training have assessed maintenance in a variety of settings for a variety of skills. Following maintenance assessments, booster sessions are commonly used to re-train skills that did not maintain at criterion levels. The current project assessed the maintenance of caregivers' skills following a training package used to teach three behavior management techniques (use reinforcement, pivot, protect-redirect) at a large, residential care facility. Procedures were developed to assess caregivers' maintenance of the three behavior management techniques using a pre-test- post-test design. If needed, skills were re-established using 5-20 minute booster sessions. The results showed that time between post-test and maintenance did not seem to have a strong effect on maintenance scores. In general, post-test scores were somewhat indicative of maintenance scores, and patterns were most apparent across tools. digital.library.unt.edu/ark:/67531/metadc849622/
The Evolution of the Improvisational Vocabulary of Marc Johnson
This study examines the evolution of the improvisational vocabulary utilized by bassist Marc Johnson over the course of his career. Through interviews and musical analysis the study contextualizes Johnson’s musical influences, considers how they shaped his development, and examines his role in the legacy of the stylistic lineage established by Scott LaFaro with the Bill Evans Trio. A survey of literature concerning Johnson, Scott LaFaro and Eddie Gomez is included, as well as a discussion of the impact of apprenticeship on Johnson’s career. The study illuminates aspects of Johnson’s current vocabulary and how he has synthesized influences to create a distinctive vocabulary, not derivative of Scott LaFaro or Eddie Gomez, but incorporating elements of their style in the composition of his own voice. digital.library.unt.edu/ark:/67531/metadc849710/
Examination of the Alignment between the SHRM Competency Model and Undergraduate Syllabi of Human Resources and Management Degree Programs in Texas
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. digital.library.unt.edu/ark:/67531/metadc849740/
Expansion of Musical Styles, Function of Texture, and Performing Techniques in Brian Lock's Sonic Archaeologies No. 1
British composer Brian Lock merges the composition styles of Alexander Goehr, Henryk Górecki and Witold Lutoslawski in his innovative works for instrumental sounds and electronics. His most recent work for flute, Sonic Archaeologies No.1, was premiered at the University of North Texas by Mary Karen Clardy, flute; Brian Lock, piano/electric keyboard; and Daniel Pardo, laptop/live mixing. The purpose of this dissertation is to provide flutists with artistic and technical guidance in preparing this work for flute, prerecorded orchestra, interactive electronics and improvisatory accompaniment. Sonic Archaeologies No. 1, a piece in five movements (Black Rain, Psychomania, Kodo, Susperia, and Deep in the Machine), incorporates contemporary techniques to create sounds other than the Western concert flute, with the use of live reinforcement devices such as microphones and time-based audio effects within a D.A.W. (Digital Audio Workstation.) Reggae, Hip-Hop and cinematic styles are juxtaposed within the work, fusing current genres with traditional rhythmic forms like the ones found in a bourrée. As the solo instrument, flute provides more textural than melodic elements, and the performer is required to interact with an unpredictable sonic soundscape as a result of the improvisatory element of the keyboards and computer. The notation of Sonic Archaeologies No.1 invites interpretation blending and altering traditional sounds through microphones and a processed signal flow. The performance guide will address acoustical considerations when the flute sound is being manipulated by dynamic and time-based processors in live performance; the interaction between the flute, electronics and acoustic spaces; the elements of sound production that provide interpretation of contemporary popular styles; and the opportunities for the performer to find, explore and develop artistry beyond the limitations of music notation. digital.library.unt.edu/ark:/67531/metadc849630/
An exploration of the word2vec algorithm: Creating a vector representation of a language vocabulary that encodes meaning and usage patterns in the vector space structure.
This thesis is an exloration and exposition of a highly efficient shallow neural network algorithm called word2vec, which was developed by T. Mikolov et al. in order to create vector representations of a language vocabulary such that information about the meaning and usage of the vocabulary words is encoded in the vector space structure. Chapter 1 introduces natural language processing, vector representations of language vocabularies, and the word2vec algorithm. Chapter 2 reviews the basic mathematical theory of deterministic convex optimization. Chapter 3 provides background on some concepts from computer science that are used in the word2vec algorithm: Huffman trees, neural networks, and binary cross-entropy. Chapter 4 provides a detailed discussion of the word2vec algorithm itself and includes a discussion of continuous bag of words, skip-gram, hierarchical softmax, and negative sampling. Finally, Chapter 5 explores some applications of vector representations: word categorization, analogy completion, and language translation assistance. digital.library.unt.edu/ark:/67531/metadc849728/
Exploring Analog and Digital Design Using the Open-Source Electric VLSI Design System
The design of VLSI electronic circuits can be achieved at many different abstraction levels starting from system behavior to the most detailed, physical layout level. As the number of transistors in VLSI circuits is increasing, the complexity of the design is also increasing, and it is now beyond human ability to manage. Hence CAD (Computer Aided design) or EDA (Electronic Design Automation) tools are involved in the design. EDA or CAD tools automate the design, verification and testing of these VLSI circuits. In today’s market, there are many EDA tools available. However, they are very expensive and require high-performance platforms. One of the key challenges today is to select appropriate CAD or EDA tools which are open-source for academic purposes. This thesis provides a detailed examination of an open-source EDA tool called Electric VLSI Design system. An excellent and efficient CAD tool useful for students and teachers to implement ideas by modifying the source code, Electric fulfills these requirements. This thesis' primary objective is to explain the Electric software features and architecture and to provide various digital and analog designs that are implemented by this software for educational purposes. Since the choice of an EDA tool is based on the efficiency and functions that it can provide, this thesis explains all the analysis and synthesis tools that electric provides and how efficient they are. Hence, this thesis is of benefit for students and teachers that choose Electric as their open-source EDA tool for educational purposes. digital.library.unt.edu/ark:/67531/metadc849770/
Facilitating Positive Relationships between Foreign-Born Providers and Their Patients in South Central Pennsylvania
Foreign-born providers make up over a quarter of the physician workforce nationally. Patients in south central Pennsylvania are primarily white with limited interaction with foreigners which can produce barriers to communication and trust. This study proposes practical steps for building positive relationships between patients and their foreign-born providers. Ethnographic methods were used to interview and survey patients and providers about the relationships between foreign-born providers and patients, primarily in the Summit Health system. The results of the study provide a framework of how trust is built between patients and providers in general, suggest additional actions for foreign-born providers, and propose ways patients can do their part to achieve a positive relationship with their provider. While much of the literature on cultural competence is in the context of patients who are from minority ethnicities, this study adds to the body of research by also considering the providers as part of minority groups. digital.library.unt.edu/ark:/67531/metadc849700/
