The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

Date: August 2001
Creator: Laughlin, James Edwin
Description: This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items. While the ...

The Pettis Integral and Operator Theory

The Pettis Integral and Operator Theory

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Huettenmueller, Rhonda
Description: Let (Ω, Σ, µ) be a finite measure space and X, a Banach space with continuous dual X*. A scalarly measurable function f: Ω→X is Dunford integrable if for each x* X*, x*f L1(µ). Define the operator Tf. X* → L1(µ) by T(x*) = x*f. Then f is Pettis integrable if and only if this operator is weak*-to-weak continuous. This paper begins with an overview of this function. Work by Robert Huff and Gunnar Stefansson on the operator Tf motivates much of this paper. Conditions that make Tf weak*-to-weak continuous are generalized to weak*-to­weak continuous operators on dual spaces. For instance, if Tf is weakly compact and if there exists a separable subspace D X such that for each x* X*, x*f = x*fχDµ-a.e, then f is Pettis integrable. This nation is generalized to bounded operators T: X* → Y. To say that T is determined by D means that if x*| D = 0, then T (x*) = 0. Determining subspaces are used to help prove certain facts about operators on dual spaces. Attention is given to finding determining subspaces far a given T: X* → Y. The kernel of T and the adjoint T* of T are used ...

Physical activity and its association with selected dietary behaviors

Physical activity and its association with selected dietary behaviors

Date: August 2001
Creator: Cartwright, Amanda R.
Description: This study examined the association between level of physical activity and changes in dietary behaviors of 3,945 employees after a 10-week work-site physical activity program. Fifty-seven percent of the participants met the CDC/ACSM standard for physical activity sufficient for a health benefit. Physical activity was not significantly related to increased fruit and vegetable consumption, decreased dietary fat and calorie intake, and participants acquiring new nutrition skills. Physical activity was negatively associated with increased food label awareness. Participants who exercised sufficient for a health benefit were less likely to increase their food label awareness. Physical activity and dietary behaviors are generally not associated. Interventions to improve these behaviors should be behavior-specific.

Perceptions of assurance service services performed by certified public accountants: Accounting education assessment applications

Perceptions of assurance service services performed by certified public accountants: Accounting education assessment applications

Date: August 2001
Creator: Brubaker, Thomas F.
Description: The overall purpose of this study was to examine how Certified Public Accountants (CPAs) perceive the potential use of assurance services to assess quality in accounting education programs. Survey questionnaires were mailed to a random sample of 250 CPAs in the north central Texas area. The questionnaire was designed to obtain demographic information and information relating to the respondents' perceptions of quality assessment of accounting education programs. An analysis of the results of this study suggest the following: CPAs consider (1) certain established criteria, such as SAT scores and faculty-to-student ratios, as effective measures for assessing quality attributes in accounting education programs and (2) traditional measures currently used for quality assessment in accounting education programs as only moderately effective by CPAs. CPAs are apparently seeking increased involvement with accounting education quality assessment and formulation of educational standards. They view the potential application of assurance services to accounting education quality as a way to offer a wider range of services to the public. CPAs perceive assurance services as a type of quality assessment that can be used to complement, but not replace, some of the more effective traditional methods, and as a way of enhancing the quality assessment process for accounting ...

Characterizaton of Triethoxyfluorosilane and Tetraethoxysilane Based Aerogels

Characterizaton of Triethoxyfluorosilane and Tetraethoxysilane Based Aerogels

Access: Use of this item is restricted to the UNT Community.
Date: December 2001
Creator: Roepsch, Jodi Ann
Description: Aerogels are highly porous, low dielectric constant (low k) materials being considered by the semiconductor industry as an interlayer dielectric. Low k materials are needed to overcome capacitance problems that limit device feature sizes. Precursors triethoxyfluorosilane (TEFS) and tetraethoxysilane (TEOS) were used to prepare bulk aerogels. Samples were prepared by sol-gel methods, and then carbon dioxide supercritically-dried. Effects of varying the water to precursor ratio were studied with respect to aerogel properties and microstructure. Methods of analysis for this study include FTIR-ATR, TEM, RBS, EDS, SEM, dielectric constant determination by impedance and surface area by gas adsorption. Si-F bonds were determined to be present in both acid- and base-catalyzed TEFS as well as HF-catalyzed TEOS. Fluorine promotes a fractal network microstructure as opposed to a particle-like microstructure. Surface area and dielectric constant were determined to increase slightly with increases in the water to precursor ratio.

Spirituality, health locus of control, and wellness in organizational health promotion and wellness programs

Spirituality, health locus of control, and wellness in organizational health promotion and wellness programs

Date: August 2001
Creator: Gauthier, Janine E.
Description: The relationship between an individual's level of spirituality, health locus of control, and participating in wellness activity was investigated. The relationship between spirituality, health locus of control on physical health was also investigated. The research question was based on prior studies that reported people who are more spiritual are healthier. Does their spirituality lead to increased levels of health, or are individual's who are more spiritual more likely to proactively take control of their health and engage in health promoting behaviors? One hundred and fifteen male and female employees completed The Spiritual Involvement and Beliefs Scale (SIBS), a spirituality measure, The Multidimensional Health Locus of Control Scale, a measure of locus of control related to health and healthcare, and The Center for Disease Control's (CDC) Health Risk Appraisal, a self-report measure of participation in health behaviors. Physical measures of health were obtained by obtaining Body Mass Index, blood pressure readings, and a cholesterol screening. The current study looked at level of spirituality (internal, external), level of health locus of control (internal, powerful other, chance) and participation in wellness/health promoting behaviors and health. Correlational analyses were performed on the relationship between spirituality and health locus of control. Hierarchical multiple regressions were ...

Job Satisfaction of Juvenile Facility Directors: Results from a National Survey

Job Satisfaction of Juvenile Facility Directors: Results from a National Survey

Date: August 2001
Creator: Flanigan, Amy Renee
Description: This study utilizes a national survey to measure the job satisfaction of juvenile facility directors. The prior literature has focused on the experiences of line personnel within the adult correctional system, and this research serves to provide new information regarding this specific population. The current study will address the predictors and correlates of a director's job satisfaction. It is hypothesized that specific characteristics within the organization will predict job satisfaction. Issues regarding staff within an institution and their effect on a director's job satisfaction are the focus. Results indicate that staff issues significantly contribute to the job satisfaction of a director. Specifically, this research can be used to understand facility director retention, staff and juvenile related issues, and the effect of job satisfaction on criminal justice policy issues.

Higher Compression from the Burrows-Wheeler Transform with New Algorithms for the List Update Problem

Higher Compression from the Burrows-Wheeler Transform with New Algorithms for the List Update Problem

Date: August 2001
Creator: Chapin, Brenton
Description: Burrows-Wheeler compression is a three stage process in which the data is transformed with the Burrows-Wheeler Transform, then transformed with Move-To-Front, and finally encoded with an entropy coder. Move-To-Front, Transpose, and Frequency Count are some of the many algorithms used on the List Update problem. In 1985, Competitive Analysis first showed the superiority of Move-To-Front over Transpose and Frequency Count for the List Update problem with arbitrary data. Earlier studies due to Bitner assumed independent identically distributed data, and showed that while Move-To-Front adapts to a distribution faster, incurring less overwork, the asymptotic costs of Frequency Count and Transpose are less. The improvements to Burrows-Wheeler compression this work covers are increases in the amount, not speed, of compression. Best x of 2x-1 is a new family of algorithms created to improve on Move-To-Front's processing of the output of the Burrows-Wheeler Transform which is like piecewise independent identically distributed data. Other algorithms for both the middle stage of Burrows-Wheeler compression and the List Update problem for which overwork, asymptotic cost, and competitive ratios are also analyzed are several variations of Move One From Front and part of the randomized algorithm Timestamp. The Best x of 2x - 1 family includes Move-To-Front, ...

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Patterns of Change in Semantic Clustering in Schizophrenia Spectrum Disorders: What Can it Tell Us about the Nature of Clustering Deficits

Date: August 2001
Creator: Edwards, Kimberly
Description: Semantic clustering has been used as a measure of learning strategies in a number of clinical populations and has been found to be deficient in individuals with Schizophrenia, but less attention has been paid to the dynamic use of this strategy over the course of fixed-order learning trials. In the current study, we examined this pattern of clustering use over trials in a sample of individuals with Schizophrenia, and explored whether the addition of this dynamic information would help us to better predict specific executive deficits. Results suggested that a decrease in semantic clustering across trials was associated with some executive deficits in the predicted manner. Nonetheless, the overall semantic clustering index generally proved more effective for the purposes, suggesting that in this population, the addition of dynamic information in strategy use is not likely to add considerably to clinical prediction and understanding.
