Web-based instruction has fast become a common component of higher education. Although such instruction began as a supplemental form of interaction, it has now become a basic aspect of many college courses and degree programs. If teacher and student are not in the same place at the same time, it becomes necessary to introduce a communications medium that will not only deliver information but also provide a channel of interaction between them. This study focused on faculty training and development programs designed to impact Web-based instruction in higher education at the five largest state-funded universities in Texas within a college of education. The instrument used in this study was developed by the research to collect data relating to faculty perception of training and development opportunities available to them at their institutions, perceptions of administrative support, and technical support. The objective was to determine if there was a relationship between these items listed above and faculty members' levels of confidence and perceptions of effectiveness when teach Web-based courses. The population consisted on 151 faculty members at the University of Texas at Austin, Texas A&M University, the University of Houston, the University of North Texas, and Texas Tech University. This research study …

The purpose of the study was to investigate the application of cognitive load theory to the design of online instruction. Students in three different courses (N = 146) were measured on both learning performance and perceptions of mental effort to see if there were any statistically significant differences. The study utilized a quasi-experimental posttest-only control group design contrasting modified and unmodified instructional lessons. Both groups were given a posttest to measure knowledge gained from the lesson (cognitive domain of learning) and perceptions of mental effort involved. Independent samples t-tests were used to compare the mean performance scores of the treatment groups (i.e. the sections using redesigned materials) versus the control groups for all three courses. Cohen's d was also computed to determine effect size. Mental effort scores were similarly compared for each group on the overall cognitive load score, for a total of six data points in the study. Of the four hypotheses examined, three (H1, H2, H4) found no statistically significant difference between the experimental and control groups. Negative significance was found between the experimental and control group on the effect of modality (H3). On measures of cognitive load, no statistically significant differences were found.

Although most people have experienced word-finding difficulty at one time or another, there are no clinical instruments able to reliably distinguish normal age-related effects from pathology in word-finding impairment. Two experiments were conducted to establish a modified version of the Boston Naming Test (BNT) that includes latency times, the Boston Naming Test of Latencies (BNT-L), in order to improve the instrument's sensitivity to mild to moderate word-finding impairment. Experiment 1: Latency times on the 60-item BNT (Goodglass et al., 2001) for 235 healthy adults' ages 18-89 years were collected on a representative sample. Qualitative features of the BNT items, statistical analyses, IRT, and demographic considerations of age, gender, education, vocabulary, race and culture, helped create a reduced BNT-L version with 15 of the most discriminating items. Statistically sound and sophisticated normative tables are provided that adjust for unseen covariates. Response latencies did not indicate earlier age-related decline in an optimally healthy sample. Experiment 2: Twenty-three patients referred for neuropsychological testing were administered the BNT-L. Patients referred for evaluation of mild cognitive impairment or possible dementia produced significantly different response BNT-L latencies from the healthy sample whereas patients referred for mild brain injury evaluation did not. Normal word-finding problems were discussed …

This research was two-fold in its purpose: the first purpose being to assess the perceived relevance of the current state competency standards adopted in Texas by the State Board for Educator Certification (SBEC) as they apply to the work of the educational diagnostician and the second being to examine the diagnostician's perceived ability of training institutions to prepare professionals for the field of special education evaluation. This study examined the perceptions of educational diagnosticians (N = 432) through the use of a survey instrument. Specifically the survey instrument was designed to assess diagnosticians' perceptions of importance of the SBEC competencies to special education evaluation in general, and to their practice in particular; the frequency with which they use the competencies; and their degree of training to meet the demands of the competencies through their preparatory program. Results indicate variability with regard to the perceived importance of the competencies and the degree of preparation to meet the demands of the competencies in practice.

This dissertation explores how contemporary, small-press, speculative fiction deviates from other genres in depicting the processes of consciousness in narrative. I study how the confluence of contemporary cognitive theory and experimental, small-press, speculative fiction has produced a new narrative mode, one wherein literature portrays not the product of consciousness but its process instead. Unlike authors who worked previously in the stream-of-consciousness or interior monologue modes, writers in this new narrative mode (which this dissertation refers to as "the little weird") use the techniques of recursion, narratological anachrony, and Ulric Neisser's "ecological self" to avoid the constraints of textual linearity that have historically prevented other literary modes from accurately portraying the operations of "self." Extrapolating from Mieke Bal's seminal theory of narratology; Tzvetan Todorov's theory of the fantastic; Daniel C. Dennett's theories of consciousness; and the works of Darko Suvin, Robert Scholes, Jean Baudrillard, and others, I create a new mode not for classifying categories of speculative fiction, but for re-envisioning those already in use. This study, which concentrates on the work of progressive, small-press, speculative writers such as Kelly Link, Forrest Aguirre, George Saunders, Jeffrey Ford, China Miéville, and many others, explores new ideas about narrative "coherence" from the points …

Established interspecific metabolic allometric relationships do not adequately describe the complexity and variable physiological states of developing animals. Consequently, intraspecific allometric relationships of oxygen consumption and carbon dioxide production as a function of body mass; the respiratory quotient; the function of the silk cocoon; and body composition were investigated for each distinct developmental stage of the silkworm, Bombyx mori. Whole animal O2 consumption in Bombyx ranged from 0.00064 + 0.000047 ml O2 .hr-1 at larval instar I to 0.77 + 0.06 ml O2 .hr-1 in pre-pupal, falling to 0.21+ 0.01 ml O2 .hr-1 in the pupae. Those instars having a significant relationship between O2 consumption as a function of body mass, the slope of the line relating O2 consumption to body mass varied between 0.99 and 1.02, while across all instars the slope was 0.82. Developmental allometry should be presented for individual developmental stages because the individual allometric exponents of the stages can be significantly different from the overall allometric exponent throughout development and in some cases, the overall allometric exponent can be a statistical artifact. The first larval instar of Bombyx mori has the lowest cross sectional area of high metabolic tissue of the midgut (27%) and had one …

The black-tailed prairie dog (Cynomys ludovicianus) has experienced dramatic declines over much of its historical range due to habitat loss, plague, poisonings, and shootings. Many populations now occur as isolated genetic relicts. A multiple locus genetic profile was obtained using microsatellite analyses of six polymorphic nucleotide repeats from 319 black-tailed prairie dogs collected from 16 colonies throughout the state of Texas. This assessment revealed that existing populations have sufficient variation at all six loci to verify the usefulness of this approach as a primary genetic tool in conservation and preservation. The data reveals regional-dependent frequency patterns as well as support for founder/bottleneck effects for several of the 16 sites. Although the prairie dog population in Texas as a whole may appear genetically diverse, considerable genetic divergence has already occurred among the subpopulations (FST = 0.164). Isolation by distance is supported by genic differentiation analysis (P < 0.001) and pairwise correlation analysis between genetic distance and geographic distance (P < 0.001). Prairie dogs from six (COC, LUBA, LUBC, LUBD, LUBE, and TAR) of the original 16 sites have been relocated or exterminated, or were in the process of being relocated. Results indicated the following colonies (COT, DAL, HOW, and HUD) are …

This study investigates how perceptions vary in athletic trainers regarding issues pertaining to women in the profession. Subjects included 1500 male and 1500 female certified athletic trainers who responded to 44 demographic and perceptions survey items used to determine whether perceptions were different based on the respondent's gender. Results were compared to a previously disseminated survey in 1996 to also determine if perceptions had changed from 10 years earlier. Results regarding the presentation of awards and the attainment of leadership positions in the organization were also compared to actual data collected. The data suggested that males perceptions had not changed, but females' perceptions had changed, in that females perceived that opportunities had improved. Data regarding the number of females who had ascended to leadership positions or had received awards did not support these perceptions, however, and female athletic trainers continue to struggle to obtain equality in both of these areas. Additionally, homosocial reproduction continues to influence the decreased number of women who are hired into various jobs, or advance into leadership positions, maintaining patriarchy in the athletics arena and in the athletic training organizations. Results suggested that because athletic training has been dominated by men since its inception, patriarchy continues …

The abstract includes a detailed analysis of the quartet as well as idiomatic aspects of the music. In addition, a background of composer/performer relationships is outlined.

Using a correlational design, this study examined relationships among and between differentiation, profile elevation, gender and educational level (predictors) and depression, confidence, and vocational identity (criterion). Clients presenting for counseling services (n = 90) with a career concern at a large, metropolitan university were included in the study. Six assumptions were examined using three single hierarchical regression analyses to reveal relationships among and between variables. Two research assumptions were confirmed at the .05 level of significance. Bivariate correlations were computed to examine the structure coefficients. Beta weights and structure coefficients were examined to determine the relative contribution of the predictors in the regression model. Results indicated that differentiation, profile elevation, gender and educational level did not predict significant variance in depression and vocational identity. However, differentiation, profile elevation, and educational level did significantly predict confidence (p< .0001).

This study addresses the academic, social, and self-image self-concepts of females ages 13-17 who are labeled emotionally and behaviorally disordered by their public school systems and are in residential treatment, and females ages 13-17 who are adjudicated, or labeled “juvenile offenders” and are involved with the juvenile justice system. The purpose of this study is to examine and compare the self-concepts of these populations of adolescent females. Research questions focus on whether or not there is a difference in the confidence scores of self-image, academic, and social self-concepts, the importance scores of self-image, academic, and social self-concepts, and the confidence composite and outcome composite scores among female adolescents according to whether or not the female is adjudicated. Results show no statistically significant differences on seven of the eight measures. On the eighth measure, a statistically significant difference was found, with the non-offenders having a higher Outcome Confidence Composite score than the offenders.

The primary purpose of this study is to address performance issues in the Polish Fantasy, Op. 19, by examining characteristics of Polish folk dances and how they are incorporated in this unique work by Paderewski. The study includes a comprehensive history of the fantasy in order to understand how Paderewski used various codified generic aspects of the solo piano fantasy, as well as those of the one-movement concerto introduced by nineteenth-century composers such as Weber and Liszt. Given that the Polish Fantasy, Op. 19, as well as most of Paderewski's compositions, have been performed more frequently in the last twenty years, an analysis of the combination of the three characteristic aspects of the Polish Fantasy, Op.19 - Polish folk music, the generic rhetoric of a fantasy and the one-movement concerto - would aid scholars and performers alike in better understanding the composition's engagement with various traditions and how best to make decisions about those traditions when approaching the work in a concert setting. Chapter 1 provides biographical and factographical information about Paderewski as a composer, pianist, and statesman. Chapter 2 examines characteristics of Polish folk music with regard to melody, rhythm and tempo. Musical examples of the Polish folk songs …

This study examined the extent of research and teaching on higher education programs in the United States that focuses on for-profit higher education. This descriptive study used a 30-item questionnaire to gather the information reported here. This survey instrument was sent to the entire population of interest. This population was made up of all of the programs in higher education that are listed in the ASHE Higher Education Program Directory, which is produced by the Association for the Study of Higher Education. The results of this research show that little research and teaching is being done that has a primary focus on for-profit higher education. Recommendations on how to address this are provided.

The search for a satisfactory model for complexity, meant as an intermediate condition between total order and total disorder, is still subject of debate in the scientific community. In this dissertation the emergence of non-Poisson renewal processes in several complex systems is investigated. After reviewing the basics of renewal theory, another popular approach to complexity, called modulation, is introduced. I show how these two different approaches, given a suitable choice of the parameter involved, can generate the same macroscopic outcome, namely an inverse power law distribution density of events occurrence. To solve this ambiguity, a numerical instrument, based on the theoretical analysis of the aging properties of renewal systems, is introduced. The application of this method, called renewal aging experiment, allows us to distinguish if a time series has been generated by a renewal or a modulation process. This method of analysis is then applied to several physical systems, from blinking quantum dots, to the human brain activity, to seismic fluctuations. Theoretical conclusions about the underlying nature of the considered complex systems are drawn.

Since the birth of the United States in 1776, Greek-letter societies have been an integral part of American higher education. Research on the impact of Greek membership varies at best, and often is in conflict from study to study. This study surveyed students affiliated with Greek-letter organizations at the University of North Texas. The research examined the college adaptability of Greek students by gender in five areas: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, and attachment to the institution. The study, conducted in the spring of 2006 at the University of North Texas had 80 respondents. The Student Adaptability to College Questionnaire (SACQ) consisted of 67 items on a 9-point scale. The SACQ is designed to assess how well students adapt to the demands of the college experience. Raw scores and percentile rankings were determined by t-test calculations. Test scores were expressed through t-scores in relation to the standardized sample. Data show no statistical significance in any of the five areas studied: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, or attachment to the institution. Female participants scored higher on all scales than male participants, indicating a slightly higher level of adjustment, though not enough to be significant. Both …

The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among …

Because there has been a paucity of research on the educational needs of females with academic, behavioral, and emotional problems involved with the juvenile justice system, this study has been an attempt to classify and compare specific characteristics of this population. In particular, it examined their demographics, disability prevalence rates, along with academic, behavioral, and emotional functioning levels, in order to further understand their relationship to the resocialization or recidivism of the different groups of female juveniles incarcerated in the state of Texas, and contribute to the research for further developing successful prevention and intervention programs. Various demographic factors of the female juveniles in this study were examined: (a) offender type, (b) county of commitment, (c) race/ethnicity, (d) age at first referral, and (e) English language proficiency. Prevalence rates of special education disabilities were determined. Academic functioning was measured by (a) IQ; (b) last school grade completed; (c) Test of Adult Basic Education (TABE) reading gain score; and (d) TABE math gain score. Behavioral functioning was indicated through (a) offense history, (b) documented behavior incidents, and (c) total risk score. Emotional functioning included DSM-IV diagnoses and treatment needs. Due to the design of the research being a descriptive exploration, the …

Sergei Mikhailovich Liapunov (1859-1924) was a distinguished Russian composer, pianist and teacher of the late 19th and early 20th century whose works are relatively unknown. His piano pieces were highly regarded and performed by pianists such as Konstantin Igumnov, Josef Hofmann, Josef Lhévinne, Ferruccio Busoni, and Vladimir Horowitz. However, they are rarely included in modern pianists' repertoire both in Russia and abroad, and are often viewed merely for their historic significance. Works of Liapunov are characterized by a life-affirming character and monumental beauty largely inspired by the images of nature as well as the sounds of his native Russian folk songs and dances. His music rarely conveys the urgency or profound melancholy which is often seen in the music composed during the same period by Rachmaninoff and Scriabin. Liapunov continued and enriched the great traditions of Russian music started by Glinka and The Mighty Five. He did not discover bold new ways of composing, and at the same time did not succumb to the temptation of following contemporary musical trends. The Twelve Transcendental Etudes, op. 11, dedicated to the memory of Franz Liszt, are masterpieces of immense value both from a technical and artistic standpoint. Just like Liszt's études, they …

Research shows children in an online environment often search by browsing, which relies heavily on recognition and content knowledge, so catalog systems for children must use effective symbols or pictorial representations, which correspond with children's own cognitive schema and level of recognition knowledge. This study was designed to look at the success of young children (ages 5 to 8) in searching 3 online public library catalogs designed for them, and it focused specifically on the pictorial representations and text descriptors used in the systems' browsing hierarchy. The research sought answer whether young children (ages 5 to 8) are really poor searchers because of cognitive development and lack of technology skills or if system design is the major reason for poor search results; i.e., Do current children's online catalog designs function in a manner that is compatible with information seeking by children? Although these results can not be generalized, this study indicates that there was a disconnect between the cognitive abilities of young users and catalog design. The study looked at search success on the 3 catalogs in relation to the catalog characteristics and individual user characteristics and makes 3 significant contributions to the field of library and information science. The …

The trumpet, or some ancestral form of the trumpet, has existed nearly as long as civilization itself. Despite its long history, however, the trumpet's solo repertoire remained limited and relatively unvaried until the second half of the twentieth century. Like most music, the American trumpet sonatas from the 1950s are a reflection of the culture and history surrounding their composition. The purpose of this research is to show how the trumpet sonatas by George Antheil, Kent Kennan, Halsey Stevens, and Burnet Tuthill are both distinctly American and unmistakably from the 1950s. The post-war era in America is often viewed as a time of unbridled optimism stemming from economic prosperity and the nation's military and industrial supremacy. The decade of the 1950s is often viewed today as a simpler, happier time in America's history. The trumpet sonatas of this era reflect this primarily in their ebullient rhythms and brilliant, often heroic melodies. However, darker characteristics of the decade (the rise of communism, for example) also make veiled appearances in these four sonatas. After an overview of the social and musical trends of the decade, the central chapter of the work delineates formal, thematic, and tonal structures of each of the four …

This study explored the relationship between the personality construct of hardiness and public speaking anxiety. Although hardiness has been widely explored in a variety of anxiety-arousing life events, its relationship with communication anxiety had not been previously studied. Therefore, hardiness, public speaking trait anxiety, and public speaking state anxiety were measured in a course requiring an oral presentation assignment. One hundred fifty students enrolled in a basic speech communication course participated in the study. A statistically significant correlation was revealed between hardiness and trait communication anxiety. Students higher in hardiness reported lower trait communication apprehension in three contexts: 1) meeting, 2) interpersonal, and 3) group. Overall, students did not differ on measures of hardiness and a fourth communication context: public speaking anxiety. Likewise, on measures of hardiness and state public speaking anxiety, students did not differ.

This dissertation focuses on the clarinet music of Luigi Bassi (1833-1871), an Italian clarinetist and composer. Biographical information and performance history for Luigi Bassi are included. Bassi wrote 27 works for clarinet, including 15 opera fantasies or transcriptions. Most of his works are housed in the Milan Conservatory library. This document provides analysis of all but two of Bassi's 27 works. For Bassi's pieces with ties to opera, I identified his source material and discussed the ways in which he manipulated the material. A brief synopsis of each opera is included. This study serves as a performance guide for those seeking to perform Bassi's clarinet works.

The Thai government has strongly advocated for the learner-centered education for the past decade. Success For Life Thailand (SFLT), a brain-research-based early childhood education program blended with the theories of the developmentally appropriate practices and child-centered philosophies, has been implemented in Thailand for over 8 years. The purposes of the present study were to: (a) describe the current statuses of the Thai early childhood educators' learner-centered beliefs and practices, (b) identify if the SFLT training workshop affects teachers' learner-centered beliefs and practices, and (c) examine if other variables, along with familiarity with the SFLT program, predict teachers' learner-centered beliefs and practices. Ninety-three preschool and kindergarten teachers participated in the study. Among them, 17 were SFLT trainees in 1999 and 2000 (i.e., the previously trained group), 43 were trained in Year 2006 (the currently trained group), and the others were comparable to the currently trained group by matching the key personal and school variables. The Teachers Beliefs and Practices Survey: 3-5 Year Olds (Burts et al., 2000) and the Learner-Centered Education: the Assessment of Learner- Centered (ALCP) for K-3 (McCombs, 2001) were used to collect data on the various domains of the learner-centered beliefs and practices. Findings reveal that: (a) Thai …

Snow Spell is an interactive composition for erhu, flute, cello, piano, and Max/MSP interactive computer music system. This one-movement piece, Snow Spell, is intended to depict the beauty of a snow scene by presenting four different impressions of snow envisioned by the composer through music. The definition, history, and significance of interactive music are explored. Various modes of interactivity to control signal processing modules, and technical considerations for signal routing and level control in the interactive computer music system are also explored. Chinese music elements in Snow Spell including pentatonic scales, glissandi, and quotations from the Chinese folk tune River of Sorrow are investigated.
