Approximately 20% of children experience serious mental health problems severe enough to meet diagnosis criteria, and less than one third of these children receive the services they need. Identifying effective school-based counseling interventions provides a viable and accessible solution, especially for families with financial barriers. This randomized, controlled outcome study examined the effectiveness of Adlerian play therapy (AdPT) compared to reading mentoring (RM) with 58 kindergarten through third grade students who qualified with clinical levels of disruptive behavior in the classroom. Participants were identified as 48% Latino, 33% European American, and 19% African American. Approximately four-fifths of participants were male. Children were randomly assigned to AdPT (experimental group) or RM (active control group) for 16 sessions of treatment. Children in both groups participated in twice weekly, individual, 30-minute interventions that took place in their schools. Results from a two (group) by two (repeated measures) split plot ANOVA indicated that, compared to the RM group over time, the AdPT group demonstrated statistically significant improvement on (a) disruptive behaviors in the classroom, as directly observed by objective raters and as reported by teachers, and (b) stress in the teacher-child relationship, as reported by teachers. Teachers and observers were blinded to children's treatment group assignment. AdPT demonstrated moderate to large effect sizes on all measures, indicating the practical significance of treatment. Further, 72% of children receiving AdPT improved from clinical/borderline levels of disruptive behavior problems to more normative functioning post-intervention, demonstrating the clinical significance of results. Whereas further research is warranted, results from this preliminary study are promising and support the use of AdPT in elementary schools to meet the needs of children exhibiting disruptive classroom behavior.
Soar! is a musical composition written for wind ensemble and computer music. The total duration of the work is approximately 10 minutes. Flocking behavior of migratory birds serves as the most prominent influence on the imagery and local structure of the composition. The cyclical nature of the birds' journey inspires palindromic designs in the temporal domain. Aesthetically, Soar! portrays the fluid shapes of the flocks with numerous grains in the sounds. This effect is achieved by giving individual parts high degree of independence, especially in regards to rhythm. Technically, Soar! explores various interactions among instrumental lines in a wind ensemble, constructs overarching symmetrical structures, and integrates a large ensemble with computer music. The conductor acts as the leader at several improvisational moments in Soar! The use of conductor-initiated musical events in the piece can be traced back through the historic lineage of aleatoric compositions since the middle of the twentieth century. [Score is on p. 54-92.]
The purpose of this study is to find out what students in the first chemistry course at the undergraduate level (general chemistry for science majors) know about the affordances of instrumentation used in the general chemistry laboratory and how their knowledge develops over time. Overall, students see the PASCO system as a useful and accurate measuring tool for general chemistry labs. They see the probeware as easy to use, portable, and able to interact with computers. Students find that the PASCO probeware system is useful in their general chemistry labs, more advanced chemistry labs, and in other science classes, and can be used in a variety of labs done in general chemistry. Students learn the affordances of the probeware through the lab manual, the laboratory teaching assistant, by trial and error, and from each other. The use of probeware systems provides lab instructors the opportunity to focus on the concepts illustrated by experiments and the opportunity to spend time discussing the results. In order to teach effectively, the instructor must know the correct name of the components involved, how to assemble and disassemble it correctly, how to troubleshoot the software, and must be able to replace broken or missing components quickly. The use of podcasts or Web-based videos should increase student understanding of affordances of the probeware.
Let R be any of the following rings: the smooth functions on R^2n with the Poisson bracket, the Hamiltonian vector fields on a symplectic manifold, the Lie algebra of smooth complex vector fields on C, or a variety of rings of functions (real or complex valued) over 2nd countable spaces. Then if H is any other Polish ring and φ:H →R is an algebraic isomorphism, then it is also a topological isomorphism (i.e. a homeomorphism). Moreover, many such isomorphisms between function rings induce a homeomorphism of the underlying spaces. It is also shown that there is no topology in which the ring of real analytic functions on R is a Polish ring.
This study was developed to examine the motivations of individuals who chose alternative routes to teacher certification and what they believe were the strengths and weaknesses of their alternative certification preparation (ACP). Data accrued from this study were based on a 55-item online survey and participant information from an online focus group. The study compared the differences between general and special educators in regards to the motivating factors affecting the decision to become a teacher, remain a teacher, and in choosing a non-university-based ACP, as well as the perceived strengths and weaknesses of the ACP. The results from the survey suggest there are differences in the motivating factors affecting general and special educator's decision to become a teacher and to remain a teacher. Additional survey results suggest there are no differences in the reason these two groups chose a non-university-based ACP. The results of the survey and the online focus group were comparable for these two groups. The remainder of this dissertation includes a review of literature related to teacher shortages and teacher preparation including alternative certification. Additionally, information on the results and analysis of the study are discussed, as well as recommendations for future research.
Doubling is defined as playing two instruments. It is becoming increasingly necessary for low brass musicians to double in the course of their careers. Euphoniumists often learn trombone, and trombonists learn euphonium. The instruments share several surface similarities but also differ in many significant ways. Interviews with six professional doublers highlight strategies for learning, teaching, and performing on both trombone and euphonium. Slide and valve technique, adjustment of intonation, tone quality, air usage, repertoire, and skill maintenance are all addressed. Trombone literature comprises a large part of the euphonium repertoire, due to the fact that most trombone pieces can be performed on euphonium. Euphoniumists should avoid playing pieces that require glissandi or extremely loud dynamics to be effective. Euphonium solos are generally too technical to be practical for trombonists to perform. Grøndahl's Concert pour trombone et piano ou orchestre is a standard piece for both instruments. When performing the piece on either instrument, it is helpful to practice the piece on both trombone and euphonium in order to tap into each instrument's strengths.
A choice paradigm was used to evaluate allocation of interlocking behavior of two groups of two participants between responses having operant consequences only and responses having cultural consequences. In a discrete trial BABABAB design, each participant could select one of three options, which delivered either 3 or 5 points. In B (cultural consequence) conditions, two of the options had additional effects: the 3-point option also added 3 points to the other participant's earnings, and one of the 5-point options also subtracted 5 points from the other participant's earnings. The third option was unchanged in both conditions and delivered 5 points to the participant who selected it. Results indicated that participants in both groups initially frequently produced response combinations that earned 8 points for one or the other individual (and 0 or 3 points for the other), but allocation of responding increasingly changed to combinations that produced 6 points for each individual. This shift in performances away from maximum individual reinforcement towards maximum group reinforcement indicates cultural contingencies did not act in concert with operant contingencies, suggesting they are different mechanisms of selection.
Wireless sensor networks are composed of sensor nodes, which can monitor an environment and observe events of interest. These networks are applied in various fields including but not limited to environmental, industrial and habitat monitoring. In many applications, the exact location of the sensor nodes is unknown after deployment. Localization is a process used to find sensor node's positional coordinates, which is vital information. The localization is generally assisted by anchor nodes that are also sensor nodes but with known locations. Anchor nodes generally are expensive and need to be optimally placed for effective localization. Passive localization is one of the localization techniques where the sensor nodes silently listen to the global events like thunder sounds, seismic waves, lighting, etc. According to previous studies, the ideal location to place anchor nodes was on the perimeter of the sensor network. This may not be the case in passive localization, since the function of anchor nodes here is different than the anchor nodes used in other localization systems. I do extensive studies on positioning anchor nodes for effective localization. Several simulations are run in dense and sparse networks for proper positioning of anchor nodes. I show that, for effective passive localization, the optimal placement of the anchor nodes is at the center of the network in such a way that no three anchor nodes share linearity. The more the non-linearity, the better the localization. The localization for our network design proves better when I place anchor nodes at right angles.
Since its premiere in 1878, Antonín Dvořák’s Piano Concerto in G Minor has been underrated and held in low regard by musicologists, critics, performers and audiences alike. Vilém Kurz (1872-1945), a Czech pianist and pedagogue, revised and reworked the piano solo part to incorporate what he considered to be added brilliance and pianistic effectiveness. However, the revised version has not increased the popularity of the work. In recent decades, this concerto has begun to appear more often in the programs and recordings are currently available, utilizing either the original piano part or Kurz's revision or a combination of both. In order to gain a broader analytical perspective and achieve a more authentic interpretation of the piece, a thorough understanding of the relation between Dvořák’s work and Kurz's revisions is indispensable. This study examines these adaptations and compares them with Dvořák’s scoring in order to gain further insight to Kurz's musical intent and pianistic aims. Examples from all movements are evaluated vis-à-vis the original to determine their purpose and musical validity.
This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but not depressive symptoms, predicted observed improvements in sleep quality (adjusted R2 = .26). Last, the implications and limitations were discussed in relation to neurotherapy practice and the associated research.
Generation and migration of helium and other point defects under irradiation causes ferritic steels based on the Fe-Cr system to age and fail. This is motivation to study point defect migration and the He equation of state using atomistic simulations due to the steels' use in future reactors. A new potential for the Fe-Cr-He system developed by collaborators at the Lawrence Livermore National Laboratory was validated using published experimental data. The results for the He equation of state agree well with experimental data. The activation energies for the migration of He- and Fe-interstitials in varying compositions of Fe-Cr lattices agree well with prior work. This research did not find a strong correlation between lattice ordering and interstitial migration energy
Research pertaining to the distortion of the squared canonical correlation coefficient has traditionally been limited to the effects of sampling error and associated correction formulas. The purpose of this study was to compare the degree of attenuation of the squared canonical correlation coefficient under varying conditions of score reliability. Monte Carlo simulation methodology was used to fulfill the purpose of this study. Initially, data populations with various manipulated conditions were generated (N = 100,000). Subsequently, 500 random samples were drawn with replacement from each population, and data was subjected to canonical correlation analyses. The canonical correlation results were then analyzed using descriptive statistics and an ANOVA design to determine under which condition(s) the squared canonical correlation coefficient was most attenuated when compared to population Rc2 values. This information was analyzed and used to determine what effect, if any, the different conditions considered in this study had on Rc2. The results from this Monte Carlo investigation clearly illustrated the importance of score reliability when interpreting study results. As evidenced by the outcomes presented, the more measurement error (lower reliability) present in the variables included in an analysis, the more attenuation experienced by the effect size(s) produced in the analysis, in this case Rc2. These results also demonstrated the role between and within set correlation, variable set size, and sample size played in the attenuation levels of the squared canonical correlation coefficient.
The Avatar for trumpet and piano by Dr. Steve Rouse is one of the most challenging compositions in the trumpet repertoire. Due to The Avatar's challenges and increasing popularity, a study is necessary to aid its performance. Each movement is performed on a different instrument: Bb piccolo (with an optional A piccolo part) for Nativity, Bb Flugelhorn for Enigma-Release and Bb trumpet for Rebirth. In addition, the performer must convey one of the work's possible programmatic meanings: (1) The Hindu belief of an Avatar and its life cycle, (2) the life of Christ or (3) the human lifecycle. Chapter 1 gives historical information about the work. Chapters 2-4 discuss each movement of The Avatar programmatically and pedagogically. Facets of each movement are analyzed including differences in programmatic choices, rehearsal techniques and sound concepts. Chapter 5 provides recording suggestions, including choosing a recording engineer, preparing and planning for a recording section, choosing a venue and the benefits of hiring a tonmeister.
The current work is an intellectual history of how blood permeated early modern Spaniards' conceptions of morality and purity. This paper examines Spanish intellectuals' references to blood in their medical, theological, demonological, and historical works. Through these excerpts, this thesis demonstrates how this language of blood played a role in buttressing the church's conception of good morals. This, in turn, will show that blood was used as a way to persecute Jews and Muslims, and ultimately define the early modern Spanish identity.
Through a qualitative study utilizing in-depth interviews, practitioner opinion was gathered regarding how Christian institutions of higher education, primarily Baptist seminaries, may better utilize formal and continuing education to prepare clergy for pastoral leadership. The sample of ten subjects for this study, drawn from the 550 active senior pastors in the Dallas Baptist Association and the Kauf-Van Baptist Association, was selected based on a maximum variation sampling method. The intention was to provide a better understanding of the leadership skills required by senior pastors, to help develop pastoral ministries curriculum and to assess the potential effectiveness of continuing education for pastoral leadership. The subjects indicated that the formal degree program of their seminary did equip them with the basic knowledge needed for pastoral leadership but it did not provide them in sufficiency with the necessary, practical skills for pastoral leadership. The pattern that emerged from the data indicates that, overall, seminaries are providing a quality education in preparing pastors for the ministry in their formal degree plans. However, seminaries may have opportunities to be of further service and to gain a competitive advantage vis a vis other seminaries by enhancing and expanding their continuing education programs.
Since the concept of business intelligence (BI) was introduced in the late 1980s, many organizations have implemented BI to improve performance but not all BI initiatives have been successful. Practitioners and academicians have discussed the reasons for success and failure, yet, a consistent picture about how to achieve BI success has not yet emerged. The purpose of this dissertation is to help fill the gap in research and provide a better understanding of BI success by examining the impact of BI capabilities on BI success, in the presence of different decision environments. The decision environment is a composition of the decision types and the way the required information is processed to aid in decision making. BI capabilities are defined as critical functionalities that help an organization improve its performance, and they are examined in terms of organizational and technological capabilities. An online survey is used to obtain the data and partial least squares path modeling (PLS) is used for analysis. The results of this dissertation suggest that all technological capabilities as well as one of the organizational capabilities, flexibility, significantly impact BI success. Results also indicate that the moderating effect of decision environment is significant for quantitative data quality. These findings provide richer insight in the role of the decision environment in BI success and a framework with which future research on the relationship between BI capabilities and BI success can be conducted. Findings may also contribute to practice by presenting information for managers and users of BI to consider about their decision environment in assessing BI success.
Transient electroluminescence (EL) was used to measure the onset of emission delay in OLEDs based on transition metal, phosphorescent bis[3,5-bis(2-pyridyl)-1,2,4-triazolato] platinum(ΙΙ) and rare earth, phosphorescent Eu(hfa)3 with 4'-(p-tolyl)-2,2":6',2" terpyridine (ttrpy) doped into 4,4'-bis(carbazol-9-yl) triphenylamine (CBP), from which the carrier mobility was determined. For the Pt(ptp)2 doped CBP films in OLEDs with the structure: ITO/NPB (40nm)/mcp (10nm)/65% Pt(ptp)2:CBP (25nm)/TPBI (30nm)/Mg:Ag (100nm), where NPB=N, N'-bis(1-naphthyl)-N-N'-biphenyl-1, 1'-biphenyl-4, MCP= N, N'-dicarbazolyl-3,5-benzene, TPBI=1,3,5-tris(phenyl-2-benzimidazolyl)-benzene, delayed recombination was observed and based on its dependence on frequency and duty cycle, ascribed to trapping and de-trapping processes at the interface of the emissive layer and electron blocker. The result suggests that the exciton recombination zone is at, or close to the interface between the emissive layer and electron blocker. The lifetime of the thin films of phosphorescent emitter Pt(ptp)2 were studied for comparison with rare earth emitter Eu(hfa)3. The lifetime of 65% Pt(ptp)2:CBP co-film was around 638 nanoseconds at the emission peak of 572nm, and the lifetime of neat Eu(hfa)3 film was obtained around 1 millisecond at 616 nm, which supports the enhanced efficiency obtained from the Pt(ptp)2 devices. The long lifetime and narrow emission of the rare earth dopant Eu(hfa)3 is a fundamental factor limiting device performance. Red organic light emitting diodes (OLEDs) based on the rare earth emitter Eu(hfa)3 with 4'-(p-tolyl)-2,2":6',2" terpyridine (ttrpy) complex have been studied and improved with respect performance. The 4.5% Eu(hfa)3 doped into CBP device produced the best power efficiency of 0.53 lm/W, and current efficiency of 1.09 cd/A. The data suggests that the long lifetime of the f-f transition of the Eu ion is a principal limiting factor irrespective of how efficient the energy transfer from the host to the dopant and the antenna effect are.
The corporate form that developed in the early 20th century created enormous pressure for corporate governance mechanisms to curb the power of corporate managers. Berle and Means, legal pluralists, warned about concentrating economic power in the hands of a small but powerful class of professional managers. They claimed this "new form of absolutism" required governmental oversight and viewed boards of directors as part of management, rather than monitors for shareholders. The Securities and Exchange Commission (SEC) proposed that corporations establish a special board committee, made up of "nonofficer members" in response to the McKesson & Robbins scandal of the late 1930s. My dissertation examines the evolution of the U.S. corporate audit committee through three specific time periods: (1) 1920-1954; (2) 1955-1986; and (3) 1987 to the passage of the Sarbanes-Oxley Act of 2002. My purpose is to determine if evolution of the audit committee throughout these periods has been a reform continually couched in symbolism or whether the audit committee concept has evolved into real reform, allowing proper corporate governance and mitigation of unchecked corporate power. My analysis is a traditional empirical analysis, relying on both primary and secondary sources to develop a coherent ordering of facts. I use narrative in a narrow sense as my historical methodology, examining patterns that emerge and interpreting facts to develop a clear understanding of demands for and uses of audit committees. I use a holistic approach in studying the data, using narrative to show how these patterns ensue from the historical data.
This two-part thesis includes a critical preface and a collection of my poems. Using three poems-Louise Glück's "Lullaby," Bob Hicok's "Poem for My Mother's Hysterectomy," and Nick Flynn's "Memento Mori"-the critical preface examines how, in poetry, the transformation of a body negotiates trauma and triggers a conceptual shift, the creation and revision of identity, and the release of the duende's inspirational force. The collection of poetry that follows seeks to transfigure the body as a way to explore the nuanced traumas of human experience.
In recent years, the use of the cimbasso has gained popularity in Giuseppe Verdi opera performances throughout the world. In the past, the tuba or the bass trombone was used regularly instead of the cimbasso because less regard was given to what Verdi may have intended. Today, one expects more attention to historical precedent, which is evident in many contemporary Verdi opera performances. However, the tuba continues to be used commonly in performances of Verdi opera productions throughout the United States. The use of the tuba in the U.S. is due to a lack of awareness and a limited availability of the cimbasso. This paper demonstrates the pedagogical and aesthetic differences between the use of the tuba and the modern cimbasso when performing the works of Giuseppe Verdi operas.
In cold-formed steel (CFS) construction, bolted connections without washers for either oversized or slotted holes may significantly expedite the installation process and lower the cost. However, the North American Specification (AISI S100, 2007) for the Design of Cold-Formed Steel Structural Members requires washers to be installed in bolted connections with oversized or slotted holes. A research project (Phase 1) sponsored by American Iron and Steel Institute (AISI) was recently completed at the University of North Texas (UNT) that investigated the performance and strength of bolted CFS connections with oversized and slotted holes without using washers. The research presented in this thesis is the Phase 2 project in which the bolted CFS connections were studied in a broader respect in terms of the failure mechanism, the material thickness, and the hole configurations. Single shear and double shear connections without washers using oversized holes, oversized combined with standard or slotted holes were experimentally examined. Combined with Phase 1 results, the Phase 2 gives a comprehensive evaluation of the behavior and strength of bolted CFS connections with oversized and slotted holes without using washers. Revisions to the existing AISI North American Specification requirements for bolted connections are proposed to account for the reduction in the connection strength caused by the oversized and slotted hole configurations without washers. Specific LRFD and LSD resistance factors and ASD safety factors for different hole configurations in terms of the new proposed methods were presented.
This study examined two art museum and school partnerships in order to learn how partnerships enable an integration of goals, participants' beliefs and values, and learning objectives. This study examined the partnerships through a social constructivist lens and used narrative analysis as way to interpret participants' stories about collaboration. The research found three major themes among participants' stories. Participants: a) valued good communication to establish relationships between partners, b) believed partnership offered students experiences that educated the whole person, and c) felt that students making meaning by interacting in the museum environment was an indicator of success. The study closes with discussion of the researchers' own constructions as they developed throughout the study.
Resilience implies the concept of buoyancy. Specifically, it denotes an individual's capacity to persevere and even do well in the face of adversity. Service-learning is pedagogy often used to enable students to apply classroom learning in a real world context. The goal of this study was to examine the effects of service-learning upon college student resilience. The study utilized a convenience sample of undergraduate students (N = 172) across three disciplines including counseling, social work and kinesiology. In a pre-post test design, the CD-RISC was employed to measure resilience of the experimental and control groups. Factor analysis of the CD-RISC was also conducted in order to explore interrelationship of the variables among the data. One undergraduate sample (N = 210) was used to conduct the EFA before determining a best fit factor structure for this study's population. A repeated measures analysis of variance was employed to detect any differences between pre-post test groups. No statistical significance was found across pre and post-test among the two groups (p=.49, η2=.00). However significant results were found between the experimental and control groups (p=.00, η2 =.09). Examination of mean score differences among demographic variable yielded interesting findings across the three disciplines as well as between age and gender of the participants. Findings indicated students given freedom of choice within service-learning logistics scored greatest gains in resilience.
It is not the purpose of this dissertation to present a history of Purgatory; rather, it is to show through the history the influence of purgatorial doctrine on the English lay community and the need of that community for this doctrine. Having established the importance this doctrine held for so many in England, with an examination of the chantry institution in England, this study then examines how this doctrine was stripped away from the laity by political and religious reformers during the sixteenth century. Purgatorial belief was adversely affected when chantries were closed in execution of the chantry acts under Henry VIII and Edward VI. These chantries were vital to the laity and not moribund institutions. Purgatorial doctrine greatly influenced the development and concept of the medieval English community. Always seen to be tightly knit, this community had a transgenerational quality, a spiritual and congregational quality, and a quality extending beyond the grave. The Catholic Church was central to this definition of community, distributing apotropaic powers, enhancing the congregational aspects, and brokering the relationship with the dead. The elements of the Roman liturgy were essential to community cohesiveness, as were the material and ritual supports for this liturgy. The need of the community for purgatorial doctrine shaped and popularized this doctrine Next, an analysis of surviving and resurging elements of expiatory rites is explored; ritual, especially that surrounding death, as well as the relationship with the dead, were sorely missed when stripped away through political actions linked to Protestant belief. This deficiency of ritual aspects within the emerging Protestant religion became evident in further years as some of the same customs and rituals that were considered anathema by Protestants slowly crept back into the Protestant liturgy in an attempt to restore the relationship between the living and the dead. Strong …
This study examined the correlates between the dependent variables African-American and Hispanic student enrollment in Texas public higher education to the independent variables institution type, education region, faculty demographics, curricular offerings and student organizations. Data for African-American (n = 124,000) and Hispanic enrollment (n = 314,000) in all Texas public higher education institutions (n = 109) for the 2008 academic year were examined. Significant results, using a statistical significance of p = .005, were reported for two of the variables. A correlation of Pearson's r = .946 and statistical significance of p = .000 was observed between African-American student enrollment and the percentage representation of African-American faculty in the same institution. A correlation of Pearson's r = .982 and statistical significance of p = .000 was observed between Hispanic student enrollment and the percentage representation of Hispanic faculty in the same institution. The results of this study found significant relationships between the presence of African-American and Hispanic faculty and enrollment of African-American and Hispanic students. Recommendations are made for exploring these findings in further detail.
This paper presents methods and results of county-level population estimation using Landsat Thematic Mapper (TM) images of Denton County and Collin County in Texas. Landsat TM images acquired in March 2000 were classified into residential and non-residential classes using maximum likelihood classification and knowledge-based classification methods. Accuracy assessment results from the classified image produced using knowledge-based classification and traditional supervised classification (maximum likelihood classification) methods suggest that knowledge-based classification is more effective than traditional supervised classification methods. Furthermore, using randomly selected samples of census block groups, ordinary least squares (OLS) and geographically weighted regression (GWR) models were created for total population estimation. The overall accuracy of the models is over 96% at the county level. The results also suggest that underestimation normally occurs in block groups with high population density, whereas overestimation occurs in block groups with low population density.
The Concerto for Trombone, written in 1763 by Georg Christoph Wagenseil, is a piece in 2 movements for alto trombone and chamber orchestra. The orchestration consists of 2 parts for violin, 1 part for viola, cello and string bass, 2 French horn parts and 2 parts for flute. It is the first concerto form solo work for the alto trombone and was written during a time when wide use of this instrument had been diminished from centuries past. The Concerto for Trombone helped mark the beginning of a time when the musical expressiveness of the trombone began to be noticed in chamber genres where such attention had been lacking in previous decades. Chapter 2 examines the life and musical background of the composer. Chapter 3 discusses the history surrounding the possible origin of the Concerto and its performance history. Chapter 4 provides analytical insights into the construction and format of the piece. Chapter 5 details the creation of an urtext edition of the Concerto. Chapter 6 concludes this document with a performer's guide to the work based on the urtext edition of the solo trombone part to create the performance edition. This performance edition of the work includes historically informed solutions to the problematic technical elements of ornaments. The final section of the chapter makes suggestions regarding the preparation and performance of a historically informed version of the Concerto for Trombone.
Spectroscopic measurements of the helium atom are performed to high precision using an atomic beam apparatus and electro-optic laser techniques. These measurements, in addition to serving as a test of helium theory, also provide a new determination of the fine structure constant α. An apparatus was designed and built to overcome limitations encountered in a previous experiment. Not only did this allow an improved level of precision but also enabled new consistency checks, including an extremely useful measurement in 3He. I discuss the details of the experimental setup along with the major changes and improvements. A new value for the J = 0 to 2 fine structure interval in the 23P state of 4He is measured to be 31 908 131.25(30) kHz. The 300 Hz precision of this result represents an improvement over previous results by more than a factor of three. Combined with the latest theoretical calculations, this yields a new determination of α with better than 5 ppb uncertainty, α-1 = 137.035 999 55(64).
The experiment was an attempt to gain a more precise understanding of the temporal relation between the development of analytic units and equivalence relations. Two prompting procedures were used during training to pinpoint when eight subjects learned the conditional discriminations. Near simultaneous presentation of probe and training trials allowed for examination of the temporal relation between conditional discrimination acquisition and derived performances on stimulus equivalence probes. The data show that, for seven of eight subjects, a decreased reliance on prompts was coincident with the development of equivalence-consistent choices on either all or some probe trials, which suggests that the development of analytic units is sufficient to give rise to equivalence relations among stimuli.
The supply chain management discipline suggests that information sharing is paramount when attempting to achieve cost reductions and quality improvements. In many cases, the traditional accounting data used to support strategic decisions reflect inaccurate supply chain costs. This research explores the applications of managerial costing techniques, and how they can be used to improve the decision making capabilities of firms in the aerospace and transportation industries. The methodology used to address the research questions consisted of a hybrid of the grounded theory and multiple-case study methods. The objective of this research was to present the antecedents and barriers associated with implementing supply chain costing, and the impact that costing approaches have on strategic decision making. The research identifies a theoretical model that can be used to explain the relationships and themes associated with supply chain costing and strategic decision making. Evidence suggests that there is some movement to implement managerial accounting techniques within these two industries to capture supply chain costing information. However, the reliance on traditional financial accounting suggests that the overarching principles of supply chain management and information sharing amongst of partner firms has yet to be realized.
The purpose of this study was to develop a parent report form instrument congruent with the philosophy of child-centered play therapy. The study sought to develop an instrument with acceptable levels of construct validity, reliability, sensitivity to clinical attitudes and relationships, and responsiveness to intervention. The Child Interpersonal Relationships and Attitudes Assessment (CIRAA) and the Child Behavior Checklist (CBC) and the Parenting Stress Index (PSI) were administered to 136 parents of children aged 3 to 10. The children of the parents sample consisted of 90 males and 46 females. Exploratory factor analysis was conducted for construct validity. Parallel analysis was conducted to determine the number of factors to retain. The factor solution explained 53.86% of the variance, which is an acceptable amount of the variance. Cronbach's alpha was conducted for total scale and all subscales. Reliability scores for the total score and subscales were acceptable, with an overall reliability coefficient of .93. A Pearson's r was conducted for concurrent validity between the instrument, the CBC, and the PSI, with Pearsons' r of .75 and .74 respectively. Paired-sample t-tests using the pretest and posttest scores of the instrument in development examined the responsiveness of the instrument to play therapy intervention at the same level as the CBC and PSI. ROC curve analysis, indicated acceptable discrimination of clinical scores and adaptive scores, with a clinical score being generated from the analysis. It is the first parent-report form developed for child-centered play therapy, and provides an efficient and philosophically consistent instrument for child centered play therapists to use in clinical and research settings.
Phosphorescent organic light emitting diodes (PHOLEDs) based on efficient electrophosphorescent dopant, platinum(II)-pyridyltriazolate complex, bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II) (Pt(ptp)2) have been studied and improved with respect to power efficiency, external efficiency, chromacity and efficiency roll-off. By studying the electrical and optical behavior of the doped devices and functionality of the various constituent layers, devices with a maximum EQE of 20.8±0.2 % and power efficiency of 45.1±0.9 lm/W (77lm/W with luminaries) have been engineered. This improvement compares to devices whose emission initially could only be detected by a photomultiplier tube in a darkened environment. These devices consisted of a 65 % bis[3,5-bis(2-pyridyl)-1,2,4-triazolato]platinum(II) (Pt(ptp)2) doped into 4,4'-bis(carbazol-9-yl)triphenylamine (CBP) an EML layer, a hole transporting layer/electron blocker of 1,1-bis[(di-4-tolylamino)phenyl]cyclohexane (TAPC), an electron transport layer of 1,3,5-tris(phenyl-2-benzimidazolyl)-benzene (TPBI), and a LiF/Al cathode. These devices show the acceptable range for warm white light quadrants and qualify to be called "warm white" even w/o adding another emissive layer. Dual EML devices composed of neat Pt(ptp)2 films emitting orange and CBP: Pt(ptp)2 film emitting blue-green produced a color rendering index (CRI) of 59 and color coordinates (CIE) of (0.47,0.49) at 1000Cd/m² with power efficiency of 12.6±0.2 lm/W and EQE of 10.8±0.2 %. Devices with two blue fluorescent emission layers as singlet filters and one broad yellow emission layer from CBP: Pt(ptp)2 displayed a CRI of 78 and CIE of (0.28,0.31) at 100Cd/m² with maximum power efficiency of 6.7±0.3 lm/W and EQE of 5.7±0.2 %.
This thesis seeks to understand how political awareness affects what information one uses to indicate their approval or disapproval of Congress and its members. More concisely, do more and less aware individuals rely on the same pieces of political information to mold their opinions of Congress? The second question of concern is what role does media consumption play in informing survey respondents about Congress. Third, I consider how survey respondents use cues like the condition of the economy and presidential job performance to help formulate their opinion of Congress Finally, by applying the Congressional approval literature to incumbent level approval, I seek to advance the theory and literature on what motivates the approval of incumbents.
The purpose of this study was to explore the effects of participants' abused or nonabused status as it interacted with their age and gender in producing different patterns of Hand Test responses as a function of the age or gender of the card. Participants, 61 young adults (M age = 23) and 60 older adults (M age = 73), were presented with the original Hand Test cards, as well as four alternate versions (e.g., young male, young female, older male, and older female). Expected effects varying by age, gender, and abuse status were not found. Results indicated main effects for participant abuse status, which were largely consistent with previous Hand Test research. Significant interaction effects were also found for participant age by participant abuse status (p < .05), as well as participant age by participant gender by participant abuse status (p < .05). An interaction effect was also found for Hand Test version by participant abuse status (p < .05), Hand Test version by participant age by participant abuse status (p < .05), as well as Hand Test version by participant gender by participant abuse status (p < .05). These results suggest that the alternate forms of the cards may pull for certain responses among abused participants that would not have been identified otherwise via the standard version of the Hand Test, clinical interviews, or other projective and self-report measures of personality. Overall, the variations in Hand Test stimuli interact with participants' abuse status, and warrant the use of alternate versions of the Hand Test as a viable projective measure.
The question of post-mortem interval (PMI) or time since death is often the most sought after piece of information associated with a medical death investigation. Based on the observation that DNA degradation disproportionately affects the analysis of larger genetic loci, it was proposed that DNA degradation, as a result of autolysis or putrefaction, could prove suitable as a potential rate-of-change indicator of PMI. Nine randomly amplified polymorphic DNA (RAPD) analysis primers and three sets of directed amplification primers were evaluated to determine their suitability for use in assessing the degree of DNA fragmentation in tissue samples. They were assessed for amplicon specificity, total DNA target sensitivity, allele monomorphism and the observance of degradation-based profile changes. Markers meeting the requisite criteria were then used to assess a range samples degraded under controlled and uncontrolled conditions. Tissue samples collected from seven domestic pigs (Sus scrofa) were incubated under controlled laboratory or uncontrolled field conditions to produce samples simulating those potentially collected in a forensic case. DNA samples isolated from these specimens were then analyzed at those loci which had been determined to meet the requisite criteria. Collectively, data generated from these analyses indicate that genetic profiles generated by this approach can provide information useful for estimating the post-mortem interval, with the locus and amplicons used being most useful during the first 72 hours after death.
This study analyzed the expressive writing of college students. Twenty-two ADHD students and 22 controls were asked to write a story based on a picture story and a personal challenge. The texts were compared based on several qualitative and quantitative parameters. The results show that students in both groups presented similar text quality. Out of six qualitative parameters only one was statistically different between the two groups: ADHD students performed worse in adequacy, but only in the picture task. Students writings were also investigated using corpus based analysis. This analysis showed that ADHD students used less unusually frequent words in the picture story but more in the challenge task. Taken together the findings indicate no significant difference in expressive writing between ADHD and non ADHD college students. An explanation to this result is that college students with ADHD may have passed the filter of prior education.
This study examines the relationship between ecological sustainability and violent conflict at both the interstate and intrastate level. In particular, this study explores the effect of ecological sustainability of a society on the initiation and the occurrence of violent conflict. By developing a theory, which is named "Eco-peace," this study hypothesizes that the more ecologically sustainable the socioeconomic system of societies, the less likely the society is to initiate interstate conflict. Regarding intrastate conflict, it is hypothesized that the more ecologically sustainable the mode of development pursued by the Third World society is, the more likely that society is to experience intrastate conflicts. To test the hypotheses, this study conducts cross-national time-series analyses for 97-127 countries. Negative binomial and Poisson models are used for interstate conflict during 1960-2001, and logit and rare event logit models are used for intrastate conflict during 1960-1999. Militarized interstate dispute dataset and Uppsala Armed Conflict Program dataset are employed for interstate and intrastate conflict. For ecological sustainability, Ecological sustainability factor index and Environmental sustainability index are used. Through the analyses, this study found the supports for the theoretical argument that the ecologically unsustainable modes of development cause the initiation of interstate conflict and the incidence of intra-state conflict in the Third World.
Behavior analysts who study verbal behavior theorize that people derive relationships between stimuli - forming stimulus classes such that psychological functions transfer among stimuli and therefore affect behavior. Verbal processes are thought to play a role in cancer patients' behavioral flexibility. The current study examined if an analogue intervention produced changes in relations between health-relevant stimuli from pre- to post-test in patient and student samples. A matching-to-sample (MTS) task required participants to form three 4-member classes that included health, treatment, or neutral terms. Participants next listened to either an acceptance-based or a control-based rationale and therapy exercise, or a distracter task. Then, they were re-exposed to the MTS task. Latencies and accuracies for learning each class as well as between condition differences were examined. Finally, changes in ratings of stimuli from pre to post analogues were measured. Differences in stimuli ratings were seen in the student sample, reflecting transfer of function and some reduction in responsiveness to stimuli following intervention, but overall no learning performances are found. Discussion explores the consistency of the findings with acceptance and commitment therapy (ACT) theory in light of the seemingly lack of findings.
Previous research, as well as theory, has supported the existence of a relationship between death anxiety and loneliness in older adults but a causal examination has not been possible until now. A hypothesized model was developed which states that loneliness will lead to death anxiety mediated by cultural worldview. Longitudinal data was analyzed using Structural Equation Modeling in order to more fully explore this potentially causal relationship. The primary model was supported suggesting that loneliness can lead to death anxiety as mediated by cultural worldview. Implications and future directions are discussed.
College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and also the discrepancy between scarcity in rich and poor seasons. Second experiment results show that dyads start fit in rich seasons and become increasingly fit in poor seasons. External variables could not be ruled out; therefore, additional experiments still need to be carried out to clarify results.
Colonoscopy is an endoscopic technique that allows a physician to inspect the mucosa of the human colon. Previous methods and software solutions to detect informative frames in a colonoscopy video (a process called informative frame filtering or IFF) have been hugely ineffective in (1) covering the proper definition of an informative frame in the broadest sense and (2) striking an optimal balance between accuracy and speed of classification in both real-time and non real-time medical procedures. In my thesis, I propose a more effective method and faster software solutions for IFF which is more effective due to the introduction of a heuristic algorithm (derived from experimental analysis of typical colon features) for classification. It contributed to a 5-10% boost in various performance metrics for IFF. The software modules are faster due to the incorporation of sophisticated parallel-processing oriented coding techniques on modern microprocessors. Two IFF modules were created, one for post-procedure and the other for real-time. Code optimizations through NVIDIA CUDA for GPU processing and/or CPU multi-threading concepts embedded in two significant microprocessor design philosophies (multi-core design and many-core design) resulted a 5-fold acceleration for the post-procedure module and a 40-fold acceleration for the real-time module. Some innovative software modules, which are still in testing phase, have been recently created to exploit the power of multiple GPUs together.
This study evaluated the effectiveness of a workshop designed to train adults to use supportive verbal behavior during distressful situations. Participants were trained to provide descriptive, empathetic and hopeful statements using instructions, rationales, modeling, role-play, feedback, and rehearsal. A pre-post design was used to analyze the effects of the training on verbal and non-verbal behaviors of four females during simulation scenarios. Results indicate all four participants provided maximum support statements above pre-training levels during post-training simulation and written assessments.
The researcher examined the effectiveness of a near-death experience (NDE) learning module on reducing distressing aspects and enhancing a growth aspect of grief among bereaved adults. Participants were 22 females and 2 males; 2 identified as African American, 3 as Asian, 2 as Latina/o, and 17 as White; aged 20 to 71 years with mean age 35.3 years. In this experimental design, the researcher randomly assigned 12 participants to the experimental group and 12 participants to the waitlist no treatment control group. Participants in the experimental group received the NDE learning module intervention, which consisted of 3 sessions over consecutive weeks. Six research questions were explored. A two-factor repeated measures analysis of variance was performed on five dependent variables to determine if the two groups performed differently across time according to the pretest and posttest results of the Despair, Panic Behavior, Personal Growth, Detachment, and Disorganization subscales of the Hogan Grief Reaction Checklist (HGRC). A one-way analysis of covariance was performed on one dependent variable to determine if the groups were statistically different according to the posttest results of the Blame and Anger subscale of the HGRC. Additionally, univariate eta squared was hand calculated to determine practical significance. Findings indicated that bereaved adults who participated in the NDE learning module showed small effect size for interaction on Panic Behavior (η2 = .05) and Personal Growth (η2 = .05), large effect size for interaction on Detachment (η2 = .15), large effect size for treatment type on Blame and Anger (η2 = .15), and negligible effect size for interaction on Despair (η2 < .01) and Disorganization (η2 < .01). Although no statistically significant results were found for any of the dependent variables (p > .05), effect size findings indicated modest to substantial benefits of the NDE learning module intervention for bereaved adults …
The acquirement of a disability (e.g., spinal cord injury, traumatic brain injury, amputation, multi trauma) is a risk factor for psychological disturbance (e.g., depression). Research has established that social support and secure attachment are protective factors against psychological disturbance. Attachment patterns have also been associated with differences in perceived social support. Secure attachment and higher perceived social support have been implicated in greater levels of resilience but need to be validated with a population of individuals who have acquired a disability. The Experiences in Close Relationships, Social Provisions Scale, Connor-Davidson Resilience Scale, Personal Health Questionnaire - 9 Depression Scale, and a Demographic were administered to 102 adult inpatients at a rehabilitation hospital undergoing an individualized rehabilitation program. Two MANOVAs were conducted to examine the direct associations of attachment classifications with the major dependent variables, as well as the various social support subscales. Path analysis tested two mediational models suggested by literature. Model 1 assessed the mediating role of attachment anxiety and attachment avoidance on the effect of social support on depression and resilience. Model 2 assessed the mediating role of social support on the effect of attachment anxiety or attachment avoidance on depression and resilience. Partial support was obtained for both models based on fit indices. A small but significant difference in the fit of the models was found, favoring Model 1. Clinical and research implications for this population and the limitations of the study are discussed.
Positive psychology has led a movement that concentrates on positive characteristics. The current study examined the relationship between positive emotions, negative emotions, flourishing, languishing, and cardiovascular functioning. The study uses guided imagery to help participants recall a negative emotional event and positive emotional event in a counterbalanced order. The reverse order allowed us to examine the differential contributions of stress buffering versus facilitated recovery effects to higher levels of heart rate variability (HRV). The study also examined the relationship between mental health categories and known cardiovascular disease risk. Univariate analysis of variance revealed that positive emotions can serve as a stress buffer and dampen cardiovascular responses to a negative event. Also, analysis revealed a trend for the prediction that positive emotions can facilitate cardiovascular recovery following a negative event. Exploratory analysis did not reveal differences between a facilitated recovery group and a buffering group for cardiovascular measures. Future studies should include tighter control to help compare the differential influences of stress facilitation and stress buffering on cardiovascular functioning. The results from the study indicate that it is still too early to tell whether mental health buffers those individuals from developing CVD, and to answer whether languishing increases the risk of CVD. Longitudinal studies of young individuals without a prior history of any risk of CVD and who are flourishing or languishing might help provide answers to these questions.
The purpose of the current study was to examine the effects of using fixed time schedules with different magnitudes of stimulus delivery as treatment for pica. A functional assessment was conducted, which indicated that pica occurred across experimental conditions and was most frequent in the absence of social stimulation or contingencies. A competing stimulus assessment was then conducted to identify stimuli that could potentially compete with pica during NCR. Subsequently, an evaluation of the effects of reinforcer magnitude on NCR as a treatment of pica was conducted. Treatment results indicated that quantity of reinforcer increased the effectiveness of leaner schedules of reinforcer delivery; however, it was not possible to fade the temporal schedule to one that would have been useful in practice. In addition, limitations and future research are outlined.
Currently, standards from government agencies such as the National Institute for Occupation Safety and Health exist to aid in safeguarding individuals’ capacity for hearing, but only in factory settings in which large machines often produce loud levels of sound. Neglecting the fact that these preventative measures are only in place in the most limited of settings, no system currently exists to observe and report sound exposure levels in a manner timely or easily recognizable enough to adequately serve its purpose of hearing conservation. Musicians may also incur significant levels of risk for hearing loss in their day-to-day rehearsals and concerts, from high school marching bands to university wind bands. As a result, music school accrediting organizations such as the National Association of Schools of Music and even the European Union have begun taking steps meant to determine the risks associated with music. To meet these goals and improve upon current technologies, a system has been developed that electronically records sound levels utilizing modern hardware, increases the speed of reporting by transmitting data over computer networks and the Internet, and displays measures calculated from these data in a web browser for a highly viewable, user-friendly interface.
Extracting information from a stack of data is a tedious task and the scenario is no different in proteomics. Volumes of research papers are published about study of various proteins in several species, their interactions with other proteins and identification of protein(s) as possible biomarker in causing diseases. It is a challenging task for biologists to keep track of these developments manually by reading through the literatures. Several tools have been developed by computer linguists to assist identification, extraction and hypotheses generation of proteins and protein-protein interactions from biomedical publications and protein databases. However, they are confronted with the challenges of term variation, term ambiguity, access only to abstracts and inconsistencies in time-consuming manual curation of protein and protein-protein interaction repositories. This work attempts to attenuate the challenges by extracting protein-protein interactions in humans and elicit possible interactions using associative rule mining on full text, abstracts and captions from figures available from publicly available biomedical literature databases. Two such databases are used in our study: Directory of Open Access Journals (DOAJ) and PubMed Central (PMC). A corpus is built using articles based on search terms. A dataset of more than 38,000 protein-protein interactions from the Human Protein Reference Database (HPRD) is cross-referenced to validate discovered interactive pairs. A set of an optimal size of possible binary protein-protein interactions is generated to be made available for clinician or biological validation. A significant change in the number of new associations was found by altering the thresholds for support and confidence metrics. This study narrows down the limitations for biologists in keeping pace with discovery of protein-protein interactions via manually reading the literature and their needs to validate each and every possible interaction.
The dissertation is a philosophical approach to politicizing place and space, or environments broadly construed, that is motivated by three questions. How can geography be employed to analyze the spatialities of environmental justice? How do spatial concepts inform understandings of environmentalism? And, how can geography help overcome social/political philosophy's redistribution-recognition debate in a way that accounts for the multiscalar dimensions of environmental justice? Accordingly, the dissertation's objective is threefold. First, I develop a critical geography framework that explores the spatialities of environmental injustices as they pertain to economic marginalization across spaces of inequitable distribution, cultural subordination in places of misrecognition, and political exclusion from public places of deliberation and policy. Place and space are relationally constituted by intricate networks of social relations, cultural practices, socioecological flows, and political-economic processes, and I contend that urban and natural environments are best represented as "places-in-space." Second, I argue that spatial frameworks and environmental discourses interlock because conceptualizations of place and space affect how environments are perceived, serve as framing devices to identify environmental issues, and entail different solutions to problems. In the midst of demonstrating how the racialization of place upholds inequitable distributions of pollution burdens, I introduce notions of "social location" and "white privilege" to account for the conflicting agendas of the mainstream environmental movement and the environmental justice movement, and consequent accusations of discriminatory environmentalism. Third, I outline a bivalent environmental justice theory that deals with the spatialities of environmental injustices. The theory synergizes distributive justice and the politics of social equality with recognition justice and the politics of identity and difference, therefore connecting cultural issues to a broader materialist analysis concerned with economic issues that extend across space. In doing so, I provide a justice framework that assesses critically the particularities of place and concurrently identifies commonalities to diverse social …
The New Deal legislation of the 1930s would threaten Dallas' peaceful industrial appearance. In fact, New Deal programs and legislation did have an effect on the city, albeit an unbalanced mixture of positive and negative outcomes characterized by frustrated workers and industrial intimidation. To summarize, the New Deal did not bring a revolution, but it did continue an evolutionary change for reform. This dissertation investigated several issues pertaining to the development of the textile industry, cement industry, and the Ford automobile factory in Dallas and its labor history before, during, and after the New Deal. New Deal legislation not only created an avenue for industrial workers to achieve better representation but also improved their working conditions. Specifically focusing on the textile, cement, and automobile industries illustrates that the development of union representation is a spectrum, with one end being the passive but successful cement industry experience and the other end being the automobile industry union efforts, which were characterized by violence and intimidation. These case studies illustrate the changing relationship between Dallas labor and the federal government as well as their local management. Challenges to the open shop movement in Dallas occurred before the creation of the New Deal, but it was New Deal legislation that encouraged union developers to recruit workers actively in Dallas. Workers' demands, New Deal industrial regulations, and union activism created a more urban, modern Dallas that would be solidified through the industrial demands for World War II.
