The purpose of the study was to explore perceptual-motor differences between blind and sighted adults from a neuropsychological perspective, and to analyze differences within the blind group. Perceptual-motor abilities were examined using the Comprehensive Vocational Evaluation System (CVES), a vocational rehabilitation and neuropsychological battery designed for use with blind populations. The data were processed using Analysis of Covariance. Results showed that sighted persons had better motor abilities, while persons with blindness were more skilled at haptic identification of shape and texture. Analysis within the blind group showed that texture identification skills are better when blindness occurs earlier in life and to the extent that the blindness is total. Later onset blindness and the retention of some functional vision may not lead to a refocusing of attentional states necessary to develop haptic images. New neural connections may develop in persons with congenital/total blindness, a hypothesis in line with recent neuroradiological findings that occipital lobe activation occurs when congenitally blind individuals engage in tactile processing tasks. One implication of the findings is that teaching individuals who retain some functional vision to read Braille is probably counterproductive. These individuals would be better served by learning to use a CCTV and large print books. …

The purpose of this study was to develop a model that would enhance the development, dissemination, and adoption of educational multimedia materials. The grounded theory definition of open coding was used to analyze data collected from the 3-year Technology Leadership Web Library Project at the University of North Texas. Weekly meeting minutes, email communication, reports, notes, questionnaires, and surveys were examined to determine major factors involved in the process of product development and dissemination. From the analysis of this study, five major factors in product development and dissemination were identified. These factors were leadership, team dynamics, expert advisors, feedback, and consumers. The synthesis of the factors led to the development of the PROMOTE (process revolving around ongoing management of team and evaluative feedback) model. The PROMOTE model is based on the establishment of a system that includes leadership, development team, and expert advisors at its center. The system is tied together with well-established feedback loops for stages of evaluation. The PROMOTE model is iterative and uses consumer feedback to generate new products. The PROMOTE model differs from other product development and evaluation models both in the focus of the process and the nature of the evaluation feedback.

This study compared cooperative and individual staff development methods for planning lessons with integrated technology. Twenty-three teachers from one elementary school participated in the study. The sample was the entire population. Nine participants were assigned to the control group, and fourteen participants were assigned to the experimental group. Names of participants were randomly drawn to determine group assignment. Participants in the control group worked individually in all three staff development sessions, while participants in the experimental group chose a partner, with whom they worked cooperatively in all three staff development sessions. Each participant or pair of participants submitted a lesson plan prior to participation in three staff development sessions. Following the sessions, each participant or pair of participants submitted a lesson plan. Three independent raters rated lesson plans to determine the participants' respective levels on the Level of Technology Implementation Observation Checklist (Moersch, 2001). The ratings of the lesson plans submitted before the training were compared to those collected after the training using a two-by-two mixed model ANOVA. The occasion (pre- vs. post-test), group, and interaction variables were all statistically significant at the .1 level; however, only the occasion variable had a strong effect size. These data suggest that (1) …

Wladimir Vogel's (1896-1984) interest in twelve-tone composition began to develop in 1936 after hearing a series of lectures by Willi Reich, a music critic and supporter of the new music of the Second Viennese School. The transition for Vogel from a large-scale orchestral “classical” style, influenced by his study with Ferruccio Busoni in Berlin in the early 1920s, to a new technique involving dodecaphony is apparent in his instrumental writing, the third and fourth movements of the Konzert für Violine und Orchester (1937), as well as in his vocal writing, the Madrigaux for mixed a cappella choir (1938/39). Vogel's twelve-tone works exhibit tertian structures which are particularly emphasized by triads located as consecutive pitches within the rows. Emphasis on tertian structures are not limited to small-scale segmentation of the rows but can also be seen in the structural and tonal organization of complete movements and works. A primary example is the Konzert für Violoncello und Orchester (Cello Concerto) (1955) in which, on a smaller scale, the presentation of the row emphasizes both diminished and minor triads, and at the macro level, the structural triadic relationships unify passages within individual movements as well as the concerto as a whole. Since the …

This was a qualitative study that used the procedures of case study design while incorporating ethnographic techniques of interviewing and non-participant observation in classrooms with six selected students, six teachers, and eight interviews of selected administrators and staff members in one middle school in a large Texas urban school district. The purpose of this study was to understand the educational experiences and perceptions of selected immigrant students and their mainstream teachers. Following the method of case study design, the educational experiences of English Language Learner (ELL) students were examined in the naturally occurring context of the school and the classroom. Because the goal of case studies is to understand a given phenomenon from the perceptions of the participants (referred to as “emic” perspective) all participants were interviewed in-depth in order to understand their unique perceptions. The study took place during a five-month period in the spring of 2002. Data were analyzed concurrently during data collection and were framed by Geneva Gay's (2000) characteristics of culturally responsive teaching. The findings and interpretation of data are divided into three parts that encompass the results of the five research questions that guided this study. Part one presents the teachers' perceptions and addresses the …

This study analyzed student test scores to determine if teacher participation in an inquiry-based professional development was able to make a statistically significant difference in student achievement levels. Test scores for objectives that assessed the critical thinking skills and problem-solving strategies modeled in a science inquiry institute were studied. Inquiry-based experiences are the cornerstones for meeting the science standards for scientific literacy. State mandated assessment tests measure the levels of student achievement and are reported as meeting minimum expectations or showing mastery for specific learning objectives. Students test scores from the Texas Assessment of Academic Skills Test (TAAS) for 8th grade science and the Biology End Of Course (EOC) exams were analyzed using ANCOVA, Chi Square, and Logistic Regression, with the Iowa Test of Basic Skills (ITBS) 7th Grade Science Subtest as covariate. It was hypothesized that the students of Inquiry Institute teachers would have higher scale scores and better rates of mastery on the critical thinking objectives than the students of non-Institute teachers. It was also hypothesized that it would be possible to predict student mastery on the objectives that assessed critical thinking and problem solving based on Institute participation. This quasi-experimental study did not show a statistically significant …

The preparation of prospective music educators is a very complex undertaking that culminates with the student teaching practicum. However, the music student teaching experience may have less predictable expectations and results than the curriculum that precedes the event. The two-fold purpose of this study was (a) to investigate the music student teaching practicum in the State of Texas in an effort to establish current levels of success as perceived by the music educators involved in the process and (b) to identify any potentially problematic areas which might be in need of attention or revision. Thirty-six music educators (12 university supervisors, 12 cooperating teachers and 12 student teachers) who were recently involved in the music student teaching practicum in Texas were chosen as the sample in this two-round Delphi study. The first round Delphi survey, based on related literature, achieved consensus on 79% of the 108 item responses, and 15 of the 22 unresolved items reached consensus in round two of the Delphi process. The 34 sample members who completed the study ranked a final item in the second Delphi round concerning suggestions for the improvement of student teaching. The respondents showed a very high opinion of the music student teaching …

The purpose of this study was to determine whether: 1) Southwest Region TRIO high school students between the years 1991 - 2001 continued to college immediately after high school at rates significantly different than similar population students on national and state levels; and 2) immediate college continuation for this group was a function of social and economic characteristics including race, gender, parental education, and home-care environment. The sample included 414 TRIO program participants from Texas, Oklahoma, New Mexico, Louisiana, and Arkansas. Data on the 414 participants were gathered using an existing database containing demographic and post-secondary enrollment information on study participants. The findings of this study reveal Southwest Region TRIO students during this ten-year period continued to college immediately after high school at rates not significantly different than the national low-income population of students. Results indicate that when compared to all students in the five-state southwest region, the majority low-income, first-generation TRIO population continued to college at rates not significantly different than all-income students in the region. Findings of this study also revealed select social and economic characteristics were not predictors of immediate college continuation for this group. Finally, the study showed out-of-home care environment students continued to college at …

The secular music of the Eastern European Jews is known today as klezmer. Klezmer was the traditional instrumental celebratory music of Yiddish-speaking Ashkenazi Jews who eventually populated the Pale of Settlement, which encompassed modern-day Poland, Lithuania, Ukraine, Belarus and Romania. Due to the rise of oppression and expulsion, many klezmer musicians or klezmorim immigrated to the United States between 1880 and the early 1920s. These musicians found work in klezmer bands and orchestras as well as Yiddish radio and theater. Some of the most influential klezmorim were clarinetists Naftule Brandwein and Dave Tarras who helped develop an American klezmer style. While the American style flourished, the popularity of pure klezmer began to diminish. As American-born Jews began to prefer the new sounds of big band and jazz, klezmer was considered old-fashioned and was in danger of becoming a lost art form. During the early 1970s, a reawakening study of klezmer developed. Henry Sapoznik, Lev Liberman and Andy Statman were instrumental in creating a klezmer revival in the United States. At the same time, Argentinean-born Israeli clarinetist Giora Feidman was popularizing klezmer in Europe. Klezmer had again become popular and the revival's impact on the concert hall was inevitable. Even though …

The early childhood profession regards advocacy as a professional and ethical responsibility yet little is known about advocacy instructional practices in teacher education programs. This study surveyed selected early childhood teacher educators who currently prepare undergraduate preservice professionals in two- and four-year institutions throughout the United States to identify and evaluate the existing advocacy training practices in preservice education. The study was designed to: (a) determine what leaders in the field of early childhood believe constitutes appropriate advocacy training for preprofessionals, (b) describe the advocacy activities of teacher educators, (c) determine if there is a difference in the advocacy instructional practices of two- and four-year institutions, and (d) recommend a model for advocacy in preprofessional programs. The participants included 607 teacher educators who responded to a mailed questionnaire and 14 leaders of early childhood professional organizations who participated in telephone interviews. Participants represented 48 states and all geographic regions of the United States. Results indicate that teacher educators and leaders believe advocacy instruction is important in preparation programs. The most frequently included advocacy activities are professionalism and understanding the professional role. Advocacy skills and strategies focused on public policy were included the least. Findings show that teacher educators participate in …

The University of North Texas Stream Research Facility (UNTSRF) was designed to examine contaminant impacts on effluent-dominated stream ecosystems. Stream mesocosms, fed municipal effluent from the City of Denton, TX, Pecan Creek Water Reclamation Plant (PCWRP), were treated with 0, 15 or 140 µg/L cadmium for a 10-day study in August 2000. Laboratory toxicity test and stream macroinvertebrate responses indicated that cadmium bioavailability was reduced by constituents of effluent-dominated streams. The Biotic Ligand Model (BLM) for Cd was used to predict a 48 hour Cd EC50 for Ceriodaphnia dubia of 280 µg/L in these effluent-dominated streams. This value is higher that an EC50 of 38.3 µg/L Cd and a 7-day reproduction effect level of 3.3 µg/L Cd generated for C. dubia in reconstituted laboratory hard water. These results support use of a cadmium BLM for establishing site-specific acute water quality criteria in effluent-dominated streams. Although not affected by 15 µg/L treatments, organisms accumulated Cd in 15 µg/L treated streams. Hence, over longer exposure periods, Cd accumulation may increase and a no effect level may be lower than the observed 10-day no effect level of 15 µg/L. A toxicity identification evaluation procedure was utilized with in vitro and in vivo bioassays …

A significant body of solo literature for the trombone has been written in the last fifty years that draws as much from the jazz tradition as from that of European classical music. While much attention has been paid to these works' use of characteristic jazz rhythms, harmonies and melodic inflections, there has been little focus on timbre, the musical element that perhaps most readily distinguishes jazz from other styles of Western music. This paper focuses on the important role jazz timbres should play in a performer's interpretation of those works that are significantly influenced by jazz. It includes explorations of the significant differences in concepts of timbre between European classical music and jazz, some of the ways in which these timbral differences are produced, and methods by which performers can develop the skills necessary to produce these varied timbres. Particular attention is paid to the importance of timbre to idiomatically appropriate performances of two significant works from the solo trombone repertoire, Robert Suderburg's Night Set (Chamber Music III) and Richard Peaslee's Arrows of Time.

The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988). Histories of each composition are chronicled. An analysis of formal organization and significant style features examines musical structure, harmonic language, rhythmic character, instrumentation, …

There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of …

The main objective of this document is to explore the life and spiritual convictions of composer Peter Lieberson, and the creation of his Piano Concerto. Lieberson is a sought after composer who has won many awards and commissions. His works have been premiered and performed by some of the best musical artists of the late twentieth- and early twenty-first-century, such as Peter Serkin, Emmanuel Ax, Yo-Yo Ma, and Pierre Boulez. This study is divided into six chapters. After the Introduction, a biographical summary of Peter Lieberson's life, his spiritual beliefs and compositional style is presented. Chapter II contains background information on the Piano Concerto, along with biographical sketches of Peter Serkin, for whom the work was written, and Seiji Ozawa, music director of the Boston Symphony Orchestra and conductor of both the premier performance and Serkin's recording of the piece. Chapter III is a selective survey of the compositional techniques used in Lieberson's Concerto, in terms of the application of twelve-tone theory and the resulting octatonic, pentatonic, and whole-tone scales. Chapter IV introduces a general overview of the influence of Buddhism as a source of inspiration in the Piano Concerto. Chapter V examines aspects of performance practice issues. Chapter VI …

The purpose of this study was to investigate the association between adult learners' preferred learning style and preference for delivery mode. The subjects (n=61) were technical and billing support call center employees from an Internet company in Dallas, Texas. The participants were randomly assigned to one of six groups and given Kolb's Learning Style Inventory to assess their preference for learning style. They received training on three modules of “Influencing Others Positively,” with each module delivered via one of three methods (web-based, classroom, and blended). Participants were also administered two surveys. The first survey collected demographic information and asked which method that they expected they would prefer. The second survey was administered after the course and asked them to rank their preferences for delivery method. It was hypothesized that learning style would be significantly associated with preference for delivery method. The data was analyzed using descriptive statistics and a chi-square test of independence for the variables learning style and preferred mode of delivery. Although the chi-square test of independence did not produce statistical significance, some interesting trends were identified in the data. Specifically, a majority of the participants preferred a blended approach to training delivery (a combination of self-paced web-based …

The musical developments of the 20th century have expanded the role of the accompanist. As the compositional output of our time increases, and the opportunity to perform as soloist with an orchestra diminishes, piano reductions of an orchestral score are becoming the most frequent vehicle for concerto performances of twentieth and twenty-first century instrumental literature. While the current state of research provides solid support to many accompanists, it is in the area of instrumental accompanying, especially with regard to the challenges of playing a reduction of an orchestral score with an instrumental soloist, that the lack of discourse becomes strikingly evident. It is the goal of this study to provide the instrumental accompanist with concrete, practical approaches and considerations in order to perform an orchestral reduction in a manner consistent with the integrity of the score. Problems such as identifying the represented orchestral instruments, delineating importance of musical lines, and basic uses and misuses of pedal, articulation, and rubato are discussed. The pianist is led through ways of deciphering and negotiating specific passages, in order to guide the accompanist through the possible pitfalls and challenges unique to many orchestral reductions. By focusing on twentieth century reductions, providing examples of problems …

For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the …

Constructed wetlands are considered an inefficient technology for long-term phosphorus (P) removal. The P retention effectiveness of subsurface wetlands can be improved by using appropriate substrates. The objectives of this study were to: (i) use sorption isotherms to estimate the P sorption capacity of the two materials, masonry sand and light weight expanded shale; (ii) describe dissolved P removal in small (2.7 m3) subsurface flow wetlands; (iii) quantify the forms of P retained by the substrates in the pilot cells; and (iv) use resulting data to assess the technical and economic feasibility of the most promising system to remove P. The P sorption capacity of masonry sand and expanded shale, as determined with Langmuir isotherms, was 60 mg/kg and 971 mg/kg respectively. In the pilot cells receiving secondarily treated wastewater, cells containing expanded shale retained a greater proportion of the incoming P (50.8 percent) than cells containing masonry sand (14.5 percent). After a year of operation, samples were analyzed for total P (TP) and total inorganic P (TIP). Subsamples were fractionated into labile-P, Fe+Al-bound P, humic-P, Ca+Mg-bound P, and residual-P. Means and standard deviations of TP retained by the expanded shale and masonry sand were 349 + 169 and 11.9 …

This study details the Medically Assisted Procreation regulations in thirty-five nation-states, and explores the influence of national identity, social cultural and demographic differences on these regulations. Detailed data were gathered from ministries of health, offices of prime ministers, embassy staff, and others on regulations for each nation. These data were used to categorize the nations in regard to MAP legislation status and regulatory policy regarding marital or age restrictions; posthumous conception; sperm, ovum, or embryo donation, surrogacy; and policy on handling donors. Possible associations between national identity, social cultural, and demographic data for each nation and their regulations were explained. The thirty-five nations were treated as a population with common geographical and political ties. PRE methods, and eta coefficients were used to assess the associations. Sixteen nations have adopted MAP legislation, eight nations have either alternative regulatory guidelines or partial structures, four nations have legislation pending and possibly some laws, and seven nations are unregulated. Based upon statistical analysis, language group emerges as an important indicator for differences in MAP regulations. For example knowing a nation's language group enabled percent improved prediction of that nation's regulatory handling of embryo donation. The percent GDP spent on health care was found to …

This study used case studies to examine the leadership frames of female presidents of four-year, public and private, coeducational research institutions both from the Intensive and Extensive Carnegie classifications within the United States. The population (N=30) surveyed was sent the Leadership Orientation Questionnaire (Self) developed from the previous research conducted by Lee Bolman and Terrance Deal. The Bolman and Deal leadership frame theory condensed existing organizational theories into a four-frame perspective consisting of a structural, human resource, political, and symbolic frame. Bolman and Deal theorized that the ability to use more than one frame is considered to be critical to the success of leaders and intensify that leader's capacity for making decisions and taking effective actions. The Leadership Orientation Questionnaire (Self) contains five sections that include rating scales for personal demographics, the four frames, eight leadership dimensions, and management and leadership effectiveness. The research questions sought to identify the demographic characteristics and academic histories of the survey participants and the associations between these variables, the leadership frames represented among the survey participants, and how many, and which, of the four frames the survey participants use collectively. This study allowed its participants to examine their perceptions of their own leadership frames …

Physical activity has been demonstrated in the literature as an effective way to reduce the risk for development of chronic disease. The Transtheoretical Model (TTM) of behavior change has been developed as a means to predict and facilitate movement into healthier lifestyle behaviors. The model is centered on "stages of change", which describe a continuum of readiness to engage in a health behavior change. Stages contain temporal, qualitative, and quantitative characteristics. This was a six-month study that evaluated the effectiveness of stage-matched (theorized to be pertaining only to the maintenance stage of change) vs. generic (theorized to be pertaining to anyone, regardless of stage) newsletters in assisting subjects to attain the Maintenance stage of change. It also sought to identify further qualitative characteristics that can differentiate between the Action and Maintenance stages of change. Results indicated that monthly stage-matched newsletters were no more effective in helping subjects reaching Maintenance than were the generic newsletters. Exerciser self-schema was related to stages of change, but those relationships differed from baseline to six-month follow-up, indicating development of exerciser self-schema during the study period. Implications of this are discussed. Other concepts discussed included "structure" of change process, in that three new scores were developed …

Rapid receptive field (RF) reorganization of somatosensory neurons in the rat dorsal horn was examined using extracellular single unit recording. Subcutaneous injection of lidocaine into RFs of dorsal horn neurons results in expansion of their RFs within minutes. The expanded RFs appear adjacent to or/and proximal to original RFs. Out of 63 neurons tested, 36 (58%) show RF reorganization. The data suggest that dorsal horn of spinal cord is one of the initial sites for RF reorganization. The neural mechanisms of this effect are not well understood. We propose that changes in biophysical properties (membrane conductance, length constant) of the neurons resulting from lidocaine injection contribute to RF reorganization. Iontophoretic application of glutamate onto dorsal horn neurons that show lidocaine induced RF's expansion were used to test the model. Application of glutamate produced reduction of reorganized RFs in 9 of 20 (45%) tested cells. Application of NBQX produced no effect on either original or expanded RFs indicate that RF shrinkage effects of glutamate involve NMDA receptors. The results are consistent with the prediction of the proposed model. Subcutaneous injection of capsaicin into tactile RFs of low threshold mechanoreceptive dorsal horn neurons produced no effect on the RF sizes that are …
