Precision Atomic Spectroscopy with an Integrated Electro- Optic Modulator and DBR Diode Laser at 1083nm

Precision Atomic Spectroscopy with an Integrated Electro- Optic Modulator and DBR Diode Laser at 1083nm

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Castillega, Jaime
Description: We have explored the use of recently developed high speed integrated electro optic modulators and DBR diode lasers as a tool for precision laser studies of atoms. In particular, we have developed a technique using a high speed modulator as a key element and applied it to the study of the fine structure of the 23P state of atomic helium. This state has been of long standing interest in atomic physics and its study has been the aim of several recent experiments using various precision techniques. We present our method and results, which will describe a new method for determining the fine structure constant, and lead to a precision test of atomic theory.

A qualitative study of the use and value of financial performance indicators in selected community colleges in the state of Texas as perceived by their chief executive officers

A qualitative study of the use and value of financial performance indicators in selected community colleges in the state of Texas as perceived by their chief executive officers

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Hase, Karla Luan Neeley
Description: Throughout the United States, colleges and universities are faced with an increasing need for financial funding, while at the same time resources continue to diminish. With the limitations of available funds, community colleges must exhibit efficiencies in the operations of their institutions. External interests, such as governing boards and legislatures, require demonstration of efficient financial management. This evidence is then used to make decisions concerning future financial support for the community college. This study determined if community college chief executive officers use financial performance indicators as provided by the State Auditor's Office and if the chief executive officers of the community colleges value the compilation and the distribution of the financial performance indicators. In the selected colleges, many of the chief executive officers depend on their chief financial officer for understanding and application of financial performance indicators. The performance indicators distributed by the Auditor's Office captured only a snapshot of the college's performance, and failed to fully describe the whole college performance or specific financial events captured by the indicators. Though the indicators had flaws, either through incorrect data or lack of explanation, the CEOs did value their compilation because they provided a means for ‘getting the community college story' ...

Reactions and learning as predictors of job performance in a United States Air Force technical training program

Reactions and learning as predictors of job performance in a United States Air Force technical training program

Date: December 1999
Creator: Boyd, Steven W.
Description: This study is based on Kirkpatrick's (1996) four level evaluation model. The study assessed the correlation between and among three levels of data that resulted from evaluation processes used in the U.S. Air Force technical training. The three levels of evaluation included trainee reaction (Level 1), test scores (Level 2), and job performance (Level 3). Level 1 data was obtained from the results of a 20 item survey that employed a 5-point Likert scale rating. Written test scores were used for Level 2 data. The Level 3 data was collected from supervisors of new graduates using a 5-point Likert scale survey. The study was conducted on an existing database of Air Force technical training graduates. The subjects were trainees that graduated since the process of collecting and storing Levels 1 and 2 data in computerized database began. All subjects for this study graduated between March 1997 and January 1999. A total of 188 graduates from five Air Force specialties were included. Thirty-four cases were from a single course in the aircrew protection specialty area; 12 were from a single course in the munitions and weapons specialty area; and 142 were from three separate courses in the manned aerospace maintenance specialty ...

Reconstructions: nine movements for solo soprano, chorus, and wind ensemble

Reconstructions: nine movements for solo soprano, chorus, and wind ensemble

Date: December 1999
Creator: Makela, Steven L.
Description: Reconstructions is a nine-movement composition for solo soprano, chorus, and wind ensemble using texts from several of Emily Dickinson's poems. The soloist represents the main character in this dramatic work, and the narrative structure portrays abstract moments in this character's life. While the narrative structure of the reconstructed fragments is important to the form of the composition, other elements are also significant. Pitch structures generated from set theoretical systems, in addition to cyclic and palindromic structures are utilized throughout. Timbre also delineates the form, as various combinations of instruments and chorus create an evolving environment in which the soloist resides.

The Relationship Between Time-on-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

The Relationship Between Time-on-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

Date: December 1999
Creator: Lansford, Carl Edwin
Description: This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students. Difference between the ...

The Response of a Public School District to Charter School Competition: An Examination of Free-Market Effects

The Response of a Public School District to Charter School Competition: An Examination of Free-Market Effects

Date: December 1999
Creator: Patrick, Diane Porter
Description: The purpose of this study was to examine a school district's responses to charter schools operating within its boundaries. The selected district was the only one in the state with two large academically competitive charter schools for at least two years. Four questions guided the research: In terms of instruction, finance, communication, and leadership, how has the traditional district been impacted due to charter school existence? The exploratory research was timely since charter schools are proliferating as tax-supported public choice schools. While many have speculated about free-market effects of charter school competition on systemic educational reform, the debate has been chiefly along ideological lines; therefore, little empirical research addresses this issue. Quantitative and qualitative methodologies were used to present a comprehensive case study. Twenty-six school officials and teachers were interviewed; 159 teachers and 1576 parents were surveyed. District, community, and state education department documents were analyzed. Since charter schools have existed in the district, numerous activities have taken place. Instructional initiatives included a high school academy, expanded technology, gifted and talented, tutoring, and dropout prevention. All elementary and middle schools required uniforms. The district's state accountability rating improved from acceptable to recognized. A leadership void was perceived due to students ...

The Resurrexit from Hector Berlioz's Messe solennelle (1825): A Case Study in Self-Borrowing

The Resurrexit from Hector Berlioz's Messe solennelle (1825): A Case Study in Self-Borrowing

Date: December 1999
Creator: Gill, Sarah M.
Description: Hector Berlioz's Messe solennelle, his first publicly performed work, was important to his establishment in Paris as a composer. Although he later destroyed the Mass, he reused parts of the Resurrexit movement in three of his later works: Benvenuto Cellini (1836), the Grand messe des morts (1837), and the Te Deum (1849). This study examines the Resurrexit and its subsequent borrowings. In each instance that Berlioz borrowed from the Resurrexit, he extracted large sections and placed them in the context of later works. Each time that borrowing occurred, Berlioz constructed the surrounding music so that portions from the Resurrexit would fit stylistically and a seamlessly into the texture. In each borrowing, he left the melody unaltered, changing harmony and orchestration instead. This pattern of borrowing demonstrates that Berlioz developed his concept of melody early in his career, and that his method of self-borrowing was consistent in each subsequent use of the Resurrexit.
