Effects of a Technology Enriched Learning Environment on Student Development of Higher Order Thinking Skills
The problem for this study was to enhance the development of higher order thinking skills and improve attitudes toward computers for fifth and sixth grade students. The purpose of this study was to determine the impact of a Technology Enriched Classroom on student development of higher order thinking skills and student attitudes toward the computer. A sample of 80 sixth grade and 86 fifth grade students was tested using the Ross Test of Higher Cognitive Processes. The Ross Test was selected because of its stated purpose to judge the effectiveness of curricula or instructional methodology designed to teach the higher-order thinking skills of analysis, synthesis and evaluation as defined by Bloom. The test consisted of 105 items grouped into seven subsections. In addition, the students were surveyed using the Computer Attitude Questionnaire developed by the Texas Center for Educational Technology. The questionnaire assessed sixty-five questions combined to measure eight attitudes.

Design of a Monitoring System for a Plasma Cleaning Machine
Plasma cleaning is the most effective dry process to remove surface contaminates from a SAW (Surface Acoustical Wave) device. Consistent gas pressures, flows, and good electrical connections between the chamber shelves are necessary for the process to function predictably. In addition, operation of the monitoring system must be transparent to the plasma cleaning unit. This thesis describes a simple solution to the complex problem of monitoring a plasma cleaning system. The monitoring system uses the LabVIEW® G programming language and hardware, both products of National Instruments, Inc.®, to monitor critical parameters necessary to achieve a consistent process when cleaning these devices.

Standing in the Gap: Subposts, Minor Posts, and Picket Stations and the Pacification of the Texas Frontier, 1866-1886
This dissertation describes the various military outposts on the Texas frontier between 1866 and 1886. It is arranged geographically, with each chapter covering a major fort or geographical area and the smaller posts associated with it. Official military records and government reports serve as the primary sources of data. In 1866 when the United States Army returned to the defense of Texas after four years of civil war, the state's frontier lay open to depredations from several Indian tribes and from lawless elements in Mexico. The army responded to those attacks by establishing several lines of major forts to protect the various danger areas of the frontier. To extend its control and protection to remote, vulnerable, or strategically important points within its jurisdiction, each major fort established outposts. Two main categories of outposts existed in Texas, subposts and picket stations. Subposts served as permanent scouting camps or guarded strategic points or lines of communication. Picket stations protected outlying locations, such as stage stations, that were particularly vulnerable to attack. Because Indians raiding in Texas usually operated in fairly small groups, garrisons at outposts were similarly small. Company-sized detachments generally garrisoned subposts, and picket stations seldom held more than a dozen …

Job Satisfaction Among Women Accounting Educators
A national survey was conducted to investigate job satisfaction among women accounting educators at four-year college and universities in the United States. The purpose of the study was to determine if differences existed among women accounting educators at research, doctoral, master's, and baccalaureate institutions in three areas relating to job satisfaction: levels of job satisfaction, individual sources of job satisfaction, and structural sources of job satisfaction. Also, the relationships among these three areas of job satisfaction were examined. A stratified random sample of 755 women accounting educators was selected from the population of 1,519 women. A mailed questionnaire was used to collect data. A total of 495 (66%) questionnaires were returned. Women accounting educators expressed satisfaction with co-workers, supervision, and work. They were neutral regarding satisfaction with pay and dissatisfied with promotion opportunities. A difference was detected between satisfaction with pay and type of institution. Differences were found between individual sources of job satisfaction and type of institution. The differences were attributable to education level and the personality characteristics of conscientiousness and openness. Differences were detected between structural sources of job satisfaction and type of institution. Academic rank, salary, tenure, institutional resources, and job functions accounted for the differences. Significant …

Autophosphorylation and Autoactivation of an S6/H4 Kinase Isolated From Human Placenta
A number of protein kinases have been shown to undergo autophosphorylation, but few have demonstrated a coordinate increase or decrease in enzymatic activity as a result. Described here is a novel S6 kinase isolated from human placenta which autoactivates through autophosphorylation in vitro. This S6/H4 kinase, purified in an inactive state, was shown to be a protein of Mr of 60,000 as estimated by SDS-PAGE and could catalyze the phosphorylation of the synthetic peptide S6-21, the histone H4, and myelin basic protein. Mild digestion of the inactive S6/H4 kinase with trypsin was necessary, but not sufficient, to activate the kinase fully

Library CD-ROM LAN Performance and Patron Use: a Computer Simulation Model
In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.

Roy Harris' American Symphony - 1938: A Perspective on Its Historical Significance and Autogenetic Elements With a Performance of a Reconstructed Modern Wind Ensemble Edition
American composer Roy Harris began writing a symphony for the Tommy Dorsey band in 1938, but the piece was never completed. This dissertation project chronicles the events surrounding the interesting collaboration between the composer and the bandleader, including problems incurred during the rehearsal process, the eventual abandonment of the project, and the discovery of the little-known band work. The paper includes information on the composer's life and works, an in-depth discussion of the compositional technique that Harris called “autogenesis,” and a detailed analysis of the two surviving movements of the band piece. The piece is also discussed comparatively with other significant works in Harris' symphonic genre, most notably his Folksong Symphony, also known as his Fourth Symphony. A significant portion of the research and preparation for the project was spent reconstructing a modern wind ensemble edition of the two surviving movements. A complete score of the reconstructed edition is included as part of this project.

The Effects of a Conflicting Instruction on a Fr 5 Performance
Access:
Use of this item is restricted to the UNT Community
The purpose of this experiment was to evaluate the effects of a conflicting instruction on FR-5 performances by an ABABC design. After all four college students were consistently pressing 1-5-3 followed by sound-clips, the schedule value changed to FR-5 (A). Then they were presented with the written instruction "Press 426" (B) in addition to the previous condition. In the last condition (C), 1-5-3 responses were then scheduled for extinction in three participants and the reinforcer was changed from sound-clips to points for one participant. The results showed that unlike previous experiments, instructions did not override the scheduled contingencies. Instruction-following occurred only when there were no other contingencies (i.e., extinction of 1-5-3) or the scheduled reinforcer for FR-5 performances was weak.

Access:
Use of this item is restricted to the UNT Community
This study investigated the relationships among the variables of parenting stress, academic self-concept, and reading ability. The purpose of this study was to determine whether parenting stress and academic self-concept contributed to the child's reading ability. Two hypotheses were investigated in an effort to accomplish this purpose. The subjects used in this study were forty-nine children and their primary caretakers referred to The Child and Family Resource Center, The University of North Texas, Denton, Texas, during the academic years of 1994 through 1999. Subjects ranged in age from seven to eighteen years of age. Academically, the subjects ranged from first graders through eleventh graders. All subjects lived in and attended schools in Denton County or neighboring counties. Parental employment ranged from unskilled laborers to medical doctors. The participating families included biological, step, adoptive, single, and divorced families. Abidin's Parenting Stress Index was used to measure parental stress experienced by the primary caretaker. The Intellectual and School Status cluster of the Piers-Harris Children's Self-Concept Scale was used to measure the child's academic self-concept and the Woodcock Reading Mastery Test-Revised provided a measure of the child's reading ability. Test scores were obtained following a review of The Child and Family Resource Center's …

Effectiveness of Filial/Play Therapy Training on High School Students' Empathic Behavior with Young Children
Access:
Use of this item is restricted to the UNT Community
This study was designed to determine the effectiveness of a filial/play therapy training model with high school juniors and seniors enrolled in a Peer Assistance and Leadership program (PALs). Filial/play therapy is an intervention that focuses on strengthening and enhancing adult-child relationships. The high students are trained to be a therapeutic change agent for primary school children identified as having adjustment difficulties by utilizing basic child-centered play therapy skills in weekly play sessions with young children. Specifically, this study is designed to determine the effectiveness of filial therapy in increasing: 1) the high school students' observed empathic behavior with young children, 2) the high school students' observed attitude of acceptance toward young children, 3) the high school students' observed ability to allow self-direction in young children, and 4) the high school students' observed level of involvement with young children. The experimental group, consisting of 16 volunteer high school students enrolled in a PALs class for high school credit, received a total of 24 weeks of filial/play therapy didactic training, application, and supervision for the playtimes they conducted with pre-kindergarten/kindergarten students identified with adjustment difficulties. The comparison group consisted of 15 volunteer high school students enrolled in a PALs class for …

The Break-up of the Confederate Trans-Mississippi Army, 1865
Access:
Use of this item is restricted to the UNT Community
Unlike other Confederate armies at the conclusion of the Civil War, General Edmund Kirby Smith's Trans-Mississippi Army disbanded, often without orders, rather than surrender formally. Despite entreaties from military and civilian leaders to fight on, for Confederate soldiers west of the Mississippi River, the surrender of armies led by Generals Robert E. Lee and Joseph E. Johnston ended the war. After a significant decline in morale and discipline throughout the spring of 1865, soldiers of the Confederate Trans-Mississippi Department chose to break-up and return home. As compensation for months of unpaid service, soldiers seized both public and private property. Civilians joined the soldiers to create disorder that swept many Texas communities until the arrival of Federal troops in late June.

Geography of Tuberculosis in the Greater Accra Region of Ghana
Access:
Use of this item is restricted to the UNT Community
In Ghana, spatial patterns of TB vary for different regions and variations may occur within the same region. This study examines TB distribution in the Greater Accra Region of Ghana using Geographic Information Systems (GIS). Behavioral, cultural and economic variables associated with TB morbidity are examined. From January 1998 to June 1999, data obtained from the Ghana Ministry of Health revealed that, men had a higher TB rate than women, TB was common among the age groups 20-29 and 30-39, and the average TB rate of 67.7 per 100, 000 population in the Greater Accra Region was higher than the national average (58.6 per 100,000 population). Using the human ecology model, this study attempts to explain the spatial distribution of the disease.

Riparian Forest Width and the Avian Community in a Greenbelt Corridor Setting
Access:
Use of this item is restricted to the UNT Community
The forest avian community of the Ray Roberts Greenbelt (Denton Co., Texas) was characterized for two years using point count station sampling, from fall 1998 to summer 2000. Richness data for both breeding seasons were correlated with two-spatial metrics: width of the riparian forest and distance to the nearest edge. There were significant correlations between forest interior species richness and both spatial metrics, for both breeding seasons. Based on these data, a minimum riparian forest width threshold of 400-meters is suggested to provide habitat for forest interior species, which have lost considerable habitat through forest fragmentation. Partners in Flight breeding bird priority concern scores were used to create a habitat priority index for the Trinity River bottomland hardwood forest system

Correspondence Between Aquatic Ecoregions and the Distribution of Fish Communities of Eastern Oklahoma
I assessed fish community data collected by the Oklahoma Conservation Commission from 82 minimally impaired wadeable reference streams in eastern Oklahoma to determine whether existing aquatic ecoregions provide the best framework for spatial classification for the development of biological assessment methods and biocriteria. I used indirect ordination and classification to identify groups of sites that support similar fish communities. Although correspondence was observed between fish assemblages and three montane ecoregions, the classification system must be refined and expanded to include major drainage basins and physical habitat attributes for some areas to adequately partition variance in key measures of biological integrity. Results from canonical correspondence analysis indicated that substrate size and habitat type were the primary physical habitat variables that influenced the fish species composition and community structure.

Reactions of psychotherapists in training to religious questions
Access:
Use of this item is restricted to the UNT Community
This project investigated the spiritual well-being (SWB) of psychotherapists in training and their physiological reactions to religious questions posed by a mock client. Electrodermal activity served as an index of physiological arousal interpreted as anxiety. Thirteen psychotherapists in training at the University of North Texas were recruited. They participated in a simulated intake session with a mock client who asked the psychotherapist neutral questions, personal-other questions (POQs), and personal-religious questions (PRQs). It was discovered that the level of SWB did not affect subjects' anxiety responses to PRQs. There also was no difference in subjects' anxiety responses for POQs between high and low SWB therapists. However, psychotherapists did experience some anxiety associated with questions related to their counseling experience and expertise.

Layered Double Hydroxides and the Origins of Life on Earth
Access:
Use of this item is restricted to the UNT Community
A brief introduction to the current state of research in the Origins of Life field is given in Part I of this work. Part II covers original research performed by the author and co-workers. Layered Double Hydroxide (LDH) systems are anion-exchanging clays that have the general formula M(II)xM(III)(OH)(2x+2)Y, where M(II) and M(III) are any divalent and trivalent metals, respectively. Y can be nearly any anion, although modern naturally occuring LDH systems incorporate carbonate (CO32-), chloride (Cl-), or sulfate (SO42-) anions. Intercalated cobalticyanide anion shows a small yet observable deviation from local Oh symmetry causing small differences between its oriented and non-oriented infrared spectra. Nitroprusside is shown to intercalate into 2:1 Mg:Al LDH with decomposition to form intercalated ferrocyanide and nitrosyl groups of an unidentified nature. The [Ru(CN)6]4- anion is shown to intercalate into layered double hydroxides in the same manner as other hexacyano anions, such as ferrocyanide and cobalticyanide, with its three-fold rotational axis perpendicular to the hydroxide sheets. The square-planar tetracyano-nickelate(II), -palladate(II), and platinate(II) anions were intercalated into both 2:1 and 3:1 Mg:Al layered double hydroxides (LDH). The basal spacings in the 2:1 hosts are approximately 11 Å, indicating that the anions are inclined approximately 75 degrees relative to …
