John Harbison's status as a significant contemporary American composer is confirmed by his numerous appointments, honorary degrees, and awards. He is the recipient of nearly every major composition award, with works performed by major orchestras and in important opera houses spanning the world. This paper examines in detail Harbison's most acclaimed choral work, the 1987 Pulitzer Prize-winning The Flight into Egypt. This study of the score is a "conductor's analysis," offering a musical guide for the conductor who seeks to perform this work. To provide a context for the discussion, Chapter 1 offers a brief biographical sketch of Harbison's life and career. Chapter 2 provides the analysis of the work and includes a history from commission to premier, a discussion of Harbison's selection of text, and an examination of the pitch organization which informs the piece. In Chapter 3, I present important rehearsal and performance implications to consider when undertaking a performance of the work. Interviews with two well-regarded conductors who have performed The Flight into Egypt, David Hoose and Patrick Gardner, and the composer himself, provide valuable insight into this discourse.

The purpose of this study was to identify effective instructional programs for GED tests preparation for students in a large suburban school district. Three different nonrandom, unequal naturally occurring instructional groups at three different locations were examined. One group participated in a traditional instruction program, a second group in a test/retest program, and a third group in a computer-assisted program. The demographics of the district population, the GED population, and the individual study groups were catalogued and analyzed. The demographics of the GED population were similar to the district population but different from the GED passers. Student characteristics did affect GED success. Both quantitative and qualitative data were gathered. Random students in each of the three groups were interviewed about their experiences in GED preparation using a questionnaire. Quantitative data were analyzed using frequencies, means, correlations, and a multiple regression analysis. Since the GED credential is an alternative to the high school diploma, its use as a dropout alternative is important to every school district. The study found that instructional methods had little impact on students' success in receiving the GED credential. The overall success rate of students was low in each group. The student's reading achievement score, GPA, and …

This study analyzed the academic impact of year-round calendar schools as compared with the academic achievement of traditional calendar schools. The population studied was the 1998 public elementary schools in Texas. The academic impact was based upon the 1998 Texas Assessment of Academic Skills (TAAS) test administrated by the Texas Education Agency. The two groups of schools studied were Texas elementary schools that were on a year-round calendar schedule, and the Texas elementary schools on a traditional calendar schedule. Multiple regression statistics were used, in addition to means, and differences between the means of variables. Year-round schools (YRE), when compared to the means of traditional schools, have means lower in math scores (6.16 percent) than traditional schools. Year-round schools have fewer African Americans students (2.78%), White students (21.06%), and special education students (.25%). Year-round schools are higher in population size (72.72students), Economic Disadvantaged students (15.87%), Hispanic students (23.46%), and Mobility (3.23%).

Roseate spoonbills are colonial nesting birds with breeding grounds extending from the United States Gulf coast to the pampas of Argentina. The U.S. population suffered a severe bottleneck from 1890 to 1920. The population's recovery was slow and partially credited to migrations from Mexican rookeries, but a gene pool reduction would be expected. Five polymorphic Spoonbill autosomal short tandem repeat (STR) loci [three (GAT)n, one (AAAG)n and one (GT)n] and one Z/W-linked microsatellite exhibiting sex-specific dimorphism were isolated and characterized. The Z/W-linked STR locus accurately confirmed the sex of each bird. Allelic profiles for 51 spoonbills obtained from Dallas (Texas), Fort Worth (Texas) and Sedgwick County (Kansas) zoos revealed a non-continuous distribution of allele frequencies, consistent with the effects of a population bottleneck. Allelic frequencies also differed significantly between the isolated zoo populations. Although extra-pair copulations were suspected and difficult to document, zoos commonly used observational studies of mating pairs to determine familial relationships among adults and offspring. STR parentage analysis of recorded family relationships excluded one or both parents in 10/25 cases studied and it was further possible to identify alternative likely parents in each case. Mistaken familial relationships quickly lead to the loss of genetic variability in captive …

This study focuses on four common factors believed to affect resistance to change in public organizations. It contributes to existing literature by examining the effect of higher education and trust on the police officer's level of resistance to change and the effects of participation and communication on trust. 286 police officers from two north Texas towns responded to the survey. Regression analysis and bivariate correlations were used to determine the relationship between, resistance to change, and participation, trust, communication, information, and education and the relationship between trust and the other independent variable. The analysis failed to support previous research, which listed participation as the most important factor, but did support the concept that participation and communication improved trust.

Early in Richard Wright's Native Son, we see Bigger and his friend Gus “playing white.” Taking on the role of “J. P. Morgan,” the two young black men give orders and act powerful, thus performing their perceived role of whiteness. This scene is more than an ironic comment on the characters' distance from the lifestyle of the J. P. Morgans of the world; their acts of whiteness are a representation of how whiteness is constructed. Such an analysis is similar to my own focus in this dissertation. I argue that whiteness is a culturally constructed identity and that work serves as a performative space for defining and transgressing whiteness. To this end, I examine work and its influence on the performance of middle class and working class whiteness, as well as how those outside the definitions of whiteness attempt to “play white,” as Bigger does. Work enables me to explore the codes of whiteness and how they are performed, understood, and transgressed by providing a locus of cultural performance. Furthermore, by looking at novels written in the early twentieth century, I am able to analyze characters at a historical moment in which work was of great import. With the labor …

This study examined the relationship between Career and Technical Education (CATE) and the Academic Excellence Indicator System (AEIS), the measure of school and learner success in Texas. CATE, an established program, traditionally encourages student achievement and perpetuates best educational practices. AEIS data was collected by the Texas Education Agency. In addition, a survey was used to measure CATE effectiveness and the relationship between effectiveness and AEIS performance. Two-factor mixed repeated measures ANOVAs were used to observe group differences over time. CATE and non-CATE exit level TAAS scores for reading and math at the district level were analyzed for 2000, 2001, and 2002. CATE students had higher group means but there was not statistical significance indicating that CATE students performed as well as non-CATE. Two-factor mixed repeated measures ANOVAs were also used for analysis of differences at the district level for attendance, dropout rates, and graduation rates. There were higher group means for attendance for CATE students and there was also statistical significance indicating that CATE students attended more often then non-CATE students. There was a lower group means for dropout rate and there was also statistical significance between groups over time. This was an inverse relationship indicating that CATE students …

The social interactions between children with special needs, learning disabilities and/or attention deficit disorder (ADHD), were investigated. The children were observed in groups of three/four while creating a cooperative art project. During this activity, their interactions were recorded and coded for patterns of verbal communication. Verbal communication was evaluated through statements reflecting requests for information and materials; helping/cooperation/giving; consideration/positive reinforcement; competitiveness; intrusiveness; rejection; self-image; neutral statements; and persuasiveness. Results indicated that children with special needs tended to engage in a greater frequency of helping/cooperative/giving statements as opposed to any other verbal statements. Specifically, positive statements as opposed to negative statements classified their verbal interactions. These children also appeared to demonstrate more internalizing behaviors than externalizing behaviors. The influence of children's behaviors on children's verbal statements was examined. Results indicated that children who evidenced a disability in reading or language appeared to engage in a greater frequency of cooperative or helping statements than their non-disabled peers. Intrusive tendencies may be associated with the following: presence of a reading disability, absence of ADHD, and absence of a disability in written expression. Additionally, the conversations of children with a disability in mixed receptive language tended to evidence a greater frequency of neutral statements …

The purpose of this phenomenological study was to describe and explain teachers' perceptions about effective professional development as well as to identify the environmental factors that affect the teacher participants' ability to engage in and implement various behaviors and beliefs transferred from the professional development experience. Four teachers were studied in depth for one school year, and data collected included in-depth interviews and classroom observations. Findings indicate three main themes related to the research questions, which sought to understand how teachers perceive and describe their experiences of participating in professional development and the factors that support or constrain their instructional decision-making as it relates to new knowledge and skills acquired through professional development. These themes are that: (a) Effective professional development must have a supportive context and meaningful purpose which: meets the physical and cognitive needs of participants; focuses on improving practice, content knowledge, and pedagogy; provides participants with choice, adequate time and ownership of learning experiences; and includes opportunities for sustained learning and accountability; (b) Learning experiences are greatly affected by interpersonal relationships and opportunities for social learning and should be built upon the principles of: taking risks in the learning environment; sharing beliefs in a community of practice …

This intrinsic case study documents a community-based history expedition implemented as a project-based, voluntary, out-of-school history activity. The expedition's development was informed by the National Education Association's concept of the intensive study of history, its structure by the history seminary, and its spirit by Webb's account of seminar as history expedition. Specific study objectives included documentation of the planning, implementation, operation, and outcomes of the expedition, as well as the viability of the history expedition as a vehicle for engaging teenagers in the practice of history. Finally, the study examined whether a history expedition might serve as a curriculum of identity. Constructivist philosophy and situated learning theory grounded the analysis and interpretation of the study. Undertaken in North Central Texas, the study followed the experiences of six teenagers engaged as historians who were given one year to research and write a historical monograph. The monograph concerned the last horse cavalry regiment deployed overseas as a mounted combat unit by the U.S. Army during World War II. The study yielded qualitative data in the form of researcher observations, participant interviews, artifacts of participant writing, and participant speeches. In addition, the study includes evaluations of the historical monograph by subject matter experts. …

This dissertation chronicles my search to engage high school English students in inquiry as part of a formal research process. The perspective of critical literacy theory is used to describe the four phases of the problem posing process in shaping student research and action. Grounded in Freire's approach and consistent with Dewey and others who advocate inquiry, action and relevance, Wink's process is built into the instructional plan described in this study. Because of the real-life context of the classroom and the complex social phenomena being considered, a case study methodology was utilized in which multiple sources of data converged to develop the themes. Data sources included the work and artifacts of ten students in a tenth grade English class during the spring semester of 2008. The analysis focuses on the supports, the constraints and the impact of problem posing on the high school research assignment. The analysis, findings, and conclusions contribute to the literature in three areas: audience, reflection and grading.

The primary purpose of this study was to determine the impact of a junior high school leadership program on the academic success and leadership development of its at-risk student participants. A secondary purpose, based on impact, was to evaluate the program as a potential school-based model for adolescent at-risk intervention. The leadership program investigated in this study is unique in three ways. First, the program is in a magnet school and the student population is heterogeneously mixed as to ethnicity and socio-economic status. Second, enrollment is open to all students. Third, its curriculum goals meet research-based criteria for effective intervention practices and leadership development. Academic success indicators associated with at-risk students included achievement, conduct, attendance, and school engagement. Leadership development indicators included leadership practices students had experienced and leadership positions students had held. The design of this post hoc study was the comparison of two groups of high school students who qualified as "at-risk" during their junior high years. Data collection included district or campus reports for cumulative attendance rates, grade point averages, and conduct demerits, as well as student survey responses for school activities, leadership practices experienced, and leadership positions held. Results of multivariate and univariate inferential analyses show …

Admissions processes for health professions programs result in students entering these programs academically homogeneous. Yet some students have great difficulty with the programs. Research has shown a limited ability of traditional academic indicators to predict successful outcomes for health professions education. The purpose of this study was to examine the relationship between learning motivation and academic outcomes for students in health professions programs. The Modified Archer Health Professions Motivation Scale (MAHPMS) and a demographic survey were administered at orientation to 131 medical and 29 physician assistant students at the University of North Texas Health Science Center in the fall of 2005. At the end of the semester, the same version of the MAHPMS was administered, and final course grades and semester averages were collected. Descriptive statistics were analyzed for all the study variables. Analysis of variance was utilized to examine within subjects and between subjects differences for the learning motivation scores among programs and demographic categories. Linear regression analyses were used to determine the relationship between learning motivation scores and end-of-semester grades. And finally, logistic regression was performed to explore the ability of the motivation scores to predict academically high-risk students. Approximately three-fourths of the students indicated a preference for …

The first diamond mine in North America was discovered in 1906 when John W. Huddleston found two diamonds on his farm just south of Murfreesboro in Pike County, Arkansas. Experts soon confirmed that the diamond-bearing formation on which Huddleston made his discovery was the second largest of its kind and represented 25 percent of all known diamond-bearing areas in the world. Discovery of the field generated nearly a half century of speculative activity by men trying to demonstrate and exploit its commercial viability. The field, however, lacked the necessary richness for successful commercial ventures, and mining was eventually replaced in the early 1950s by tourist attractions that operated successfully until 1972. At that time the State of Arkansas purchased the field and converted it to a state park. Thus this work tell the rich and complicated story of America'a once and only diamond field, analyzes the reasons for the repeated failures of efforts to make it commercially viable, and explains how it eventually succeeded as a tourist venture.

Interactional and contextual models have been conceptually proposed in understanding parental influences on children. Yet, empirical model testing has been limited. The purpose of this exploratory study was to investigate the direct and indirect effects of parenting style on child social competence using structural equation modeling in a sample of 544 Chinese families with 6-9 years old children, mainly singleton, residing in Nanjing, China. Five latent models were tested: (a) the direct model between parenting style and child social competence, (b) child temperament as a moderator, (c) parent-child relationship as a mediator, (d) the interaction model between parenting style and family functioning, and (e) bidirectional models of parenting style concurrently with parent-child relationship, and family functioning predicting child social competence. Findings showed: (a) The direct relationship between parenting style and child social competence was significant in both parents with authoritative parenting style on the positive direction, whereas authoritarian and permissive parenting styles on the negative direction; (b) child temperament did not moderate parenting style on child social competence; (c) father-child relationship mediated paternal parenting style on child social competence, whereas maternal parenting style did not; (d) family functioning neither moderated nor mediated the relationship between parenting style and child social …

The present study sought to identify variables that predicted parental decision-making regarding their child's participation in a national gifted and talented identification program for middle school students and subsequent participation in recommended educational options. One hundred sixty-nine parents of students who qualified for either the 2001-2002 or 2002-2003 Duke Talent Identification Program participated in the study. The students were drawn from two large public school districts and six small private schools in a large metropolitan area in the southwestern United States. Both quantitative and qualitative methods were used to identify the variables predictive of parental decision-making regarding talent search participation. Each parent completed a questionnaire consisting of both multiple-choice and open-ended questions. Selected parents participated in structured follow-up interviews. The results of the study indicated that parental perception of the helpfulness of school personnel in explaining the purpose and process of the talent search was most predictive of participation in the talent search. The educational level of the father, parent's prior awareness of the purpose and process of talent search, and the number of enrichment activities in which the child had previously participated were also predictive of talent search participation. Qualitative data indicated that parents of both participants and nonparticipants …

This study attempted to determine the types, extent, and quality of student personnel services in colleges and universities accredited by the Accrediting Association of Bible Colleges (AABC). The Basic Services Questionnaire (BSQ) was adapted for use among Bible colleges and universities and mailed to chief student affairs officers representing 69 Bible colleges in the United States accredited by the AABC. Of the 71 surveys mailed (two institutions employed both a Dean of Men and Dean of Women), 46 were returned for a response rate of 65 percent. Chi-square tests of goodness-of-fit were performed on the data in order to categorize the types, extent, and quality of student services provided by the institutions. The Mueller-Schuessler Index of Qualitative Variation was used to determine the homogeneity, or heterogeneity, of the chief student affairs officers when grouped according to specific variables (gender, ethnic origin, major for highest degree earned, and highest degree earned). Frequency counts and percentage distributions were used on demographic data to present a profile of chief student services administrators at AABC schools. The results of the study point to four conclusions. First, the types of student personnel services provided by American Bible colleges and universities accredited by the AABC closely …

This study examined what differences in resiliency traits, if any, exist between successful and non-successful first and continuing-generation college students through the use of a survey. For the purposes of this study, first-generation students were those students whose parents have never attended college and continuing-generation college students were those students whose parents have attended some college. For the purposes of this study, the term successful was defined as those students who after being enrolled during fall 2005 re-enrolled for the spring 2006 semester and the term non-successful is defined as those students who after being enrolled fall 2005 semester failed to re-enrolled for the spring 2006 semester. A sample of 164 students was surveyed by collecting demographic data, resiliency traits, attitudinal characteristics, level of familial support, and reasons for dropping out of college. A sub-sample of 40 students participated in a face-to-face, in-depth interview. This study found that successful first-generation community college students possessed certain common qualities or resilient characteristics that include: 1) social competence, 2) problem-solving skills, 3) critical consciousness, 4) autonomy, and 5) sense of purpose. Through the face-to-face interviews common themes emerged. Many of the students used similar words to describe their feelings and experiences about beginning, …

The Texas high school class of 2005 faced a defining test that had no precedent in Texas and little nationally. Social studies testing is a relatively new addition to the world of high stakes testing currently impacting United States high schools. Although other diploma dependent areas of mandated testing have some testing history and, therefore, related paradigms for curriculum and instructional assistance, the area of social studies largely lacks that perspective. Texas Education agency provided specific school grant monies and training for the purpose of preparation for the social studies exams. This quasi-experimental study examines the scores to learn whether or not any statistically significant differences in social studies scores would exist between the schools that participated in the TEKS/Tools Training Program and the schools that did not participate in the TEKS/Tools Training Program. The two primary at-risk groups in Texas, Hispanic and low SES, were analyzed for statistically significant differences in scores. Independent t tests and ANCOVA were used to analyze the score differences between program schools and non-program schools. Results relate to individual school staffing and implementation. The at-risk groups remained flat in score gains whether they were part of the program schools or not. Results relate to …

This mixed design study surveyed members of the National Association of Student Personnel Administrators (NASPA) to determine the baseline for wellness among student affairs administrators and within the profession. In addition to describing the wellness levels of the administrators and comparing them to the wellness of the general population, the study explored how wellness is represented within the student affairs profession, as reflected in the literature and practice. Student affairs administrators' wellness was assessed utilizing the Five Factor Wel Wellness Inventory (Myers & Sweeney, 2004). Collectively, the administrators posted "well" scores on the six factors utilized in the study and scored higher than the norms reported for the 5F-Wel general population. However, there was a broad range of actual scores across individuals indicating that not everyone can be considered to be maintaining a well-balanced lifestyle. The administrators' wellness was not affected by their length of time in the student affairs profession but was negatively associated with the number of hours they worked per week. The administrators possessed a holistic view of wellness and could articulate the behaviors and conditions associated with achieving, and failing to achieve, balance. However, reported engagement in certain wellness behaviors (e.g., physical activity and healthy eating) …

Critical care nurses work in an environment rich in informative interactions. Although there have been post hoc self-report survey studies of nurses' information seeking, there have been no observational studies of the patterns and content of their on-duty information behavior. This study used participant observation and in-context interviews to describe 50 hours of the observable information behavior of a representative sample of critical care nurses in a 20-bed critical care hospital unit. The researcher used open, in vivo, and axial coding to develop a grounded theory model of their consistent pattern of multimedia interactions. The resulting Nurse's Patient-Chart Cycle describes nurses' activities during the shift as centering on a regular alternation with the patient and the patient's chart (various record systems), clearly bounded with nursing "report" interactions at the beginning and the end of the shift. The nurses' demeanor markedly changed between interactions with the chart and interactions with the patient. Other informative interactions were observed with other health care workers and the patient's family, friends and visitors. The nurses' information seeking was centered on the patient. They mostly sought information from people, the patient record and other digital systems. They acted on or passed on most of the information …

This study investigated the effects of interactive lessons and learning style on student learning outcomes in self-defense education classes. The study utilized an experimental design that incorporated four self-defense education classes at the University of North Texas (UNT) during the fall semester 2007 (N = 87). A pre-test was administered during the first week of class to determine prior knowledge of the participants. The Visual Auditory Reading/Kinesthetic Inventory (VARK) was used to assess the learning styles of the students and was completed after the pre-test of knowledge was administered. The treatment group received the interactive lesson and the control received a paper review. The difference between the pre and posttest was used as a measure of improvement of the student's learning outcomes. A 2 (treatment/control) by 2 (pretest/posttest) ANOVA with repeated measures was conducted to examine the differential improvement in knowledge across the intervention. Based on the 2-way ANOVA there was a significant difference between the treatment group and the control group based on their learning outcomes. A repeated measures ANOVA was conducted to determine if there was a significant difference between the groups based on the pre and post test scores. Based on the results of a one week …

Implicit in the call for educational reform in the teaching of social studies has been the suggestion that pursuing inquiry-based principles will lead to improvement in student achievement. The purpose of this study was to compare the effectiveness of two types of pedagogy: traditional and inquiry-based upon student achievement as measured by a standards-based, state administered examination. Second, this study examined the relationship between the treatment teachers' level of implementation and student achievement. A nonequivalent control group posttest and experimental design was used in this study. Subjects involved in this study include 84 secondary American history teachers and their respective students from a large urban public school district in Texas. The sample consisted of two groups, one taught by traditional/didactic instruction (n=48) and the other taught by inquiry-based pedagogy (n=36). Data for this study were collected using a classroom observation protocol based upon the level of use rubric developed by the concerns-based adoption model. An analysis of variance (ANOVA) (p<.05) was used to measure the effects of inquiry-based instruction and traditional pedagogy on student achievement. Student achievement results were measured by the Texas Assessment of Knowledge and Skills (TAKS) for American history, grades 8 and 11. The study found that …

Analysis of a particular north-central Texas public high school revealed a strong representation of Hispanic females in advanced academic programs, i.e., AP and GT in proportion to their representation in the overall student population. Research seems to indicate that a progressive approach to academic-potential identification; culturally effective mentoring, traditional Hispanic values, and newly emerging personal and social characteristics all seem to be contributing factors. This study seems to indicate that a new type of Hispanic female is emerging who is more assertive academically, more visible in the classroom, and less marriage-and-family oriented as might be believed by teachers, society, their peers, and perhaps even their parents.
