John Harbison's The Flight into Egypt: An Analysis for Performance (open access)

John Harbison's The Flight into Egypt: An Analysis for Performance

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.

Solo Trombone Performances at the Gewandhaus in the Nineteenth Century: a Lecture Recital, Together with Three Recitals of Selected Works of G. Jacobs, S. Sulek, E. Bloch, C. Wagenseil, W. Ross, G. Pergolesi, T. George, F. Hidas, J. Albrechtsberger and Others (open access)

Solo Trombone Performances at the Gewandhaus in the Nineteenth Century: a Lecture Recital, Together with Three Recitals of Selected Works of G. Jacobs, S. Sulek, E. Bloch, C. Wagenseil, W. Ross, G. Pergolesi, T. George, F. Hidas, J. Albrechtsberger and Others

This study investigates and documents tenor/bass trombone solo performances at the Gewandhaus, Leipzig, East Germany, between 1821 and 1876. Included is the discussion of a newly discovered composition, the Concertino fur Bassposaune und Orchester, by Carl Heinrlch Meyer, which is the earliest concerto for the tenor/bass trombone. Its performance at the Gewandhaus in 1821 marked the beginning of the solo tradition for the tenor/bass trombone, and the Leipzig Gewandhaus became one of the leading centers of solo trombone performance for the next fifty years. The study includes background information on the rise of the virtuoso soloist in nineteenth-century Germany. It specifically focuses on Friedrlch August Belcke and Carl Traugott Queisser and their performances at the Gewandhaus. All solo trombone performances at the Gewandhaus in the nineteenth century have been documented, and specific information has been provided regarding the soloists, dates of performances and repertoire performed on the concerts. The paper includes a discussion of performance reviews from the Allgemeine Musfkalische Zeitung. The conclusion discusses the importance of solo trombone performance at the Gewandhaus, and the reason for its sudden decline after 1876.

Spatial Ability in Registered Nurses (open access)

Spatial Ability in Registered Nurses

Spatial ability is the skill associated with mental relations among objects, the process of maintaining the physical aspects of an object after mentally rotating it in space. Many studies report a strong association of spatial ability with success in various areas of health care, especially surgery, radiology and dentistry. To date, similar investigations in professional nursing could not be located. Registered nurses, employed in an acute care multi-hospital setting, were surveyed using the Shipley-2Block Pattern Test, the Group Embedded Figures Test, and a newly created test of general nursing knowledge. The sample size of 123 nurses was composed of 31 male nurses and 92 female nurses. Data was collected between May and August of 2013 and analyzed using R, version 2.15.2. The present study did not demonstrate a statistically significant effect for gender differences on two measures of spatial ability. However, Cohen’s d effect sizes for mean gender differences in the present study are consistent with prior studies. This may suggest the nursing profession is comparable with other professions where males perform higher than females on spatial ability. The present study should be considered an initial step toward evaluating the relevance of spatial ability in the performance of nursing care.

A Comparative Analysis of the Effectiveness of Three Different GED Preparation Programs (open access)

A Comparative Analysis of the Effectiveness of Three Different GED Preparation Programs

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 …

The Lexicographer's Daughter: A Memoir (open access)

The Lexicographer's Daughter: A Memoir

This creative nonfiction dissertation is a memoir of the author's search for the somewhat mysterious hidden past of her father, the lexicographer Charles J. Lovell, who died in 1960, when the author was nine. Her father's early death left the author with many unanswered questions about his past and his family and so she undertakes a search to answer, if possible, some of those questions. Her search takes her to Portland, Maine; New Bedford, Massachusetts; and Pasadena, California, where she tries to discover the facts and uncover the forces that shaped her father's life. Along the way, she realizes how profoundly his death affected and shaped her own life, contributing to the theme of loss that pervades the memoir. In addition, she begins to realize how much her mother, Dixie Hefley Lovell, whose significance she previously overlooked, shaped her life. Ultimately, she comes to understand and accept that some of her questions are unanswerable.

Mother-Infant Interaction with Facially Deformed Infants (open access)

Mother-Infant Interaction with Facially Deformed Infants

This study investigated the interactions of facially deformed infants (FD) with their mothers compared to a facially nondeformed control group (FND). All mother-infant dyads were videotaped for 10 minutes during a free play period. Mothers were instructed to spend time with their baby as they normally would. The videotaped interactions of 14 FD dyads and 14 FND dyads were rated by five raters for quality of interactions, amount of vocalization, touch, and face-to-face gaze. The infants were rated on their level of attractiveness from polaroid pictures and videotapes. Mothers also completed a questionnaire which assessed their infants' temperament. Three of the studies' four hypotheses were confirmed. First, the more attractive an infant was, the better his/her interactions with the mother were judged to be. Second, FD infant dyads were rated as significantly poorer in quality of interaction than FND dyads, although FD* dyads did not spend significantly less time vocalizing, touching, or in face-to-face gaze as predicted. A significantly higher percentage of FD infants were judged as having difficult temperament relative to FND infants. Finally, as predicted it was found that infants with difficult temperaments were more likely to exhibit poorer quality interactions than infants with less difficult temperaments. These …

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program (open access)

Measuring the Effectiveness of Transfer of Learning Constructs and Intent to Transfer in a Simulation-based Leadership Training Program

The purpose of business training programs is to improve performance, which improved performance changes leadership behaviors based on the knowledge, skills, and abilities (KSAs) learned in training. One of the most common criticisms of leadership training is the tendency to focus on teaching theory but not on applying theory into practice, that is, transfer of learning. Research usually ends at the point of identifying, describing, or measuring factors that influence transfer. Ongoing research must identify what constructs in the transfer of learning process should be effectively changed or managed. There is a gap in research on the degree to which performance improvement through KSAs learned in a simulation training program actually transfer to the work environment. Additional research is needed that examines the relationship between transfer of learning and intent to transfer, which are critical outcomes in the field of human resource management and development. The purpose of the study was to examine the relationship between intent to transfer and four constructs in the transfer of learning process during a simulation-based leadership training program. Participants completed self-report assessments that measured the relationships between intent to transfer and four constructs: ability, motivation, work environment, and learner readiness. A correlational design was …

The use of the semantic differential in a study of the effects of aspirational and dissociative reference group influence on consumer behavior

The purpose of this study was to investigate the effects of aspirational and dissociative reference group influence on consumer behavior. There are two ways in which behavior is influenced by reference groups. First, reference groups influence aspiration levels and therefore play a major role in producing satisfaction or frustration. Second, reference groups influence kinds of behavior, i.e., they establish approved patterns of behavior.

A Comparison of Quantitative Skills in Texas Year-round Schools with Texas Traditional Calendar Schools

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%).

A Topological Model of Thought (open access)

A Topological Model of Thought

The problem was to develop a model of thought within the basic structure provided by general or "point-set" topology. To do this, it was necessary to make four basic assumptions. It was assumed that each individual possesses more than the classical five senses and that for each of these there exists a category of sensory data. Also, it was assumed that the Cartesian product of these categories formed a set M of thought elements for each individual, and that certain subsets of M provide support for cogitation. The relation, function, continuous function, and homeomorphism, which are used to relate sets in topology, are discussed as a possible ramification of the model for communication. The global properties of the homeomorphism and continuous function present each as a viable support for strong and meaningful communication between thought spaces of individuals.

The Effect of Accelerated Instruction on Summer Regression

The purpose of this study was to evaluate the benefit accrued to fifth-grade students who participated in a summer school accelerated instruction program utilizing accelerated instructional practices in a Texas school district. The secondary intent was to determine the program's effect on student regression or retention as measured by Measures of Academic Progress (MAP) scores and State of Texas Assessment of Academic Readiness (STAAR) tests in reading and mathematics. The district provided summer accelerated instruction to fifth-grade students who did not pass reading and/or mathematics portions of STAAR for the May administration. For this study, I focused on the 2018 summer accelerated instruction offered by the district, using a mixed methods design to analyze the effectiveness of accelerated instruction for the students who participated in the summer program. A paired samples t-test was conducted to evaluate if students who failed the May STAAR in either reading or mathematics increased their scores on the June STAAR. Also, a paired samples t-test was conducted to determine if these same students increased their fall MAP test when compared to the spring MAP test. Teachers were interviewed to determine their perceptions of the most beneficial parts of summer school for students who attended. The …

Filial Therapy with Native Americans on the Flathead Reservation

This study was designed to determine the effectiveness of the 10-week filial therapy model as an intervention for Native American parents and their children residing on the Flathead Reservation in Montana. Filial therapy is an approach used by play therapists to train parents to be therapeutic agents with their own children. Parents are taught basic child-centered play therapy skills and practice those skills during weekly play sessions with their children. The purpose of this study was to determine if filial therapy is effective in: 1) increasing parental acceptance of Native Americans residing on the Flathead Reservation of their children; 2) reducing the stress level of those parents; 3) improving empathic behaviors of those parents toward their children; 4) changing the play behaviors of children with their parents who participated in the training; and, 5) enhancing the self-concept of those children.

Teacher Perceptions of Supports that Promote Computer Self-Efficacy and Transformational Digital Pedagogy in One-to-One Learning Environments (open access)

Teacher Perceptions of Supports that Promote Computer Self-Efficacy and Transformational Digital Pedagogy in One-to-One Learning Environments

Although one-to-one technology programs are rapidly expanding in secondary schools, the literature about how to effectively leverage these programs to improve teaching and learning is relatively small. Little guidance is available for school leaders attempting to improve teachers' willingness and ability to incorporate technology effectively into their instruction. The purpose of this mixed-methods case study was to discovery what supports school leaders provide to promote high levels of computer self-efficacy and transformational digital pedagogies in one-to-one learning environments. Data were collected from English language arts, Social Studies, and science teachers in three high schools in a suburban school district in northeast Texas using an online survey, eight virtual semi-structured interviews, and two virtual focus group interviews. Data were analyzed using descriptive statistics and deductive and inductive analysis. The findings of the study reveal most teachers perceived their ability to effectively deliver digital instruction as strong, and most were able to incorporate technology into their lessons at transformational levels. The following themes emerged from data regarding teachers' perceptions of support: shared vision, realistic and supportive climate, collaboration, encouragement, job-embedded professional learning, continuous improvement, equity, and safe, legal, and ethical use.

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress (open access)

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

The activity of plant 9-lipoxygenases (LOXs) influences the outcome of Arabidopsis thaliana interaction with pathogen and insects. Evidence provided here indicates that in Arabidopsis, 9-LOXs facilitate infestation by Myzus persicae, commonly known as the green peach aphid (GPA), a sap-sucking insect, and infection by the fungal pathogen Fusarium graminearum. in comparison to the wild-type plant, lox5 mutants, which are deficient in a 9-lipoxygenase, GPA population was smaller and the insect spent less time feeding from sieve elements and xylem, thus resulting in reduced water content and fecundity of GPA. LOX5 expression is induced rapidly in roots of GPA-infested plants. This increase in LOX5 expression is paralleled by an increase in LOX5-synthesized oxylipins in the root and petiole exudates of GPA-infested plants. Micrografting experiments demonstrated that GPA population size was smaller on plants in which the roots were of the lox5 mutant genotype. Exogenous treatment of lox5 mutant roots with 9-hydroxyoctadecanoic acid restored water content and population size of GPA on lox5 mutants. Together, these results suggest that LOX5 genotype in roots is critical for facilitating insect infestation of Arabidopsis. in Arabidopsis, 9-LOX function is also required for facilitating infection by F. graminearum, which is a leading cause of Fusarium head …

Toward a Rationale for Music Education in the Public School Context Framed with both Progressive and Essentialist Considerations: Operationalizing the Ideas of William Chandler Bagley

In music education, aesthetic education and praxial music education serve as two major, guiding philosophical frameworks, yet supporters of each often conflict with one another. Furthermore, both are slightly problematic with respect to the specific context of the public school. Each framework is primarily music-based, however, music education has existed in the wider context of general education since the 1830s. Given the recent core-status designation for music education, as part of all fine arts, in the reauthorization of the Elementary and Secondary Education Act, a framework from general education that supported music education could offer benefits for the domain. However, the wider context of general education is messy as well. Two groups occupy most of the space there, and remain locked in a fundamental disagreement over the purpose of a formal education. The progressive educators, historically framed by Dewey and Thorndike, contend that education functions as societal improvement. In contrast, the essentialists contend that education functions as cultural transmission. Therefore, a more specific need for music education involves selecting a framework from general education that resolves this conflict. The writings of William Chandler Bagley indicate that he balanced both considerations of a formal education while also advancing his notion of …

The Effects of Listening Skills Instruction on Students' Academic Performance

Although it is widely assumed that listening is among the most important learning skills (Wolvin & Coakley, 1988), an examination of the literature indicates that it has been woefully neglected as subject matter in schools. Listening has also been neglected as an area of research. Surveys have been conducted to see if listening is being taught or can effectively be taught, but little evidence exists to suggest that effectively teaching listening improves students' academic performance. This study investigated the relationship between listening skills instruction and academic performance among university students. The purpose was to determine if teaching university students comprehensive listening skills improves their academic performance. It was assumed that listening can be effectively taught. The goal of the study was to compare 75 students who were enrolled in a listening course to a similar group of 75 students not enrolled in a listening course. The students were compared on the basis of grade point improvement the semester after the experimental group had completed the listening course. The t test was chosen because it can be used for testing the significance of the difference between the means of two independent samples. The grade point averages of the two groups were …
