During dynamic exercise the arterial baroreflexes have been thought to reset to the prevailing level of systemic pressure in order to modulate transient changes in blood pressure with the same sensitivity (gain) as at rest. To test this hypothesis, cardiovascular responses to dynamic exercise and carotid baroreflex responses to graded neck suction and neck pressure (NS/NP) were examined in seven men of moderate fitness (V02 = 41.4±3.6 ml O2*kg^-1*min^-1) during two levels (20% and 40% of peak oxygen uptake) of steady-state exercise. In addition, deactivation of cardiopulmonary baroreceptors has been thought to increase carotid baroreflex responsiveness in the quiescent state in man.

This thesis explores the films produced by leftist filmmakers of the 1930s which reflect the contemporary urban life in Shanghai.

The charge state dependence of M-shell x-ray production cross sections of 67HO bombarded by 2-12 MeV carbon ions with and without K-vacancies are reported. The experiment was performed using an NEC 9SDH-2 tandem accelerator at the Ion Beam Modification and Analysis Laboratory of the University of North Texas. The high charge state carbon ions were produced by a post-accelerator stripping gas cell. Ultra-clean holmium targets were used in ion-atom collision to generate M-shell x rays at energies from 1.05 to 1.58 keV. The x-ray measurements were made with a windowless Si(Li) x-ray detector that was calibrated using radiative sources, particle induced x-ray emission (PIXE), and the atomic field bremsstrahlung (AFB) techniques.

In 1983, the report A Nation at Risk catapulted school reform to the forefront of national attention. The State of Texas responded with legislation dictating curriculum and instructional time. Failure to accomplish the desired improvement in student achievement caused these mandates to be eased. In lieu of the mandates, the Texas legislature and the Texas Education Agency have set expectation standards called academic indicators. Local districts and campuses must utilize site based decision making (SBDM) to determine how each campus will meet the set standards. Dealing primarily with curriculum roles and responsibilities, this study details perceptions of principals and teachers as SBDM was being implemented in a suburban school district serving 25,000 students. Data were gathered utilizing a structured interview and a follow-up telephone interview. Addressed in the study are perceptions of: (a) role changes, (b) responsibility changes, (c) needed improvements in the implementation process, (d) teacher empowerment, (e) positive and negative elements, and (f) student achievement.

We define and construct bicentric circles with respect to three-sided polygons. Then using inherent properties of these circles, we explore both tangent properties, and areas generated from bicentric circles.

The Federation of North Texas Area Universities was mandated by the Coordinating Board of the Texas College and University System on 3 December 1968, and this consortium was given legal empowerment by the Texas State Legislature. The three federated Universities--North Texas State University, Texas Woman's University and East Texas State University--developed a plan of cooperative action to maximize use of available resources, a plan which included sharing facilities and faculty as well as developing joint program offerings. At a time in history when educational institutions were obliged to maximize their resources, minimize their expenditure, and eliminate duplication, the consortium was an innovative approach to higher education as well as an interesting alternative to having degree programs cut and funding diminished.

In the last two decades of his life, Harry S. Truman formally established the office of the ex-presidency in the public eye. The goals he wanted to accomplish and the legislation passed to help Truman achieve these aims led the way for Truman and other former presidents to play a significant role in American public life. Men who had occupied the nation's highest office had a great deal to offer their country, and Truman saw to it that he and other former presidents had the financial and the institutional support to continue serving their nation in productive ways. Although out of the White House, Harry S. Truman wanted to continue to play an active role in the affairs of the nation and the Democratic party. In pursuing this goal, he found that he was limited by a lack of financial support and was forced to turn to the federal government for assistance. While Truman was active for more than a decade after he left Washington, his two most important legacies were helping push for federal legislation to provide financial support for ex-presidents and to organize and maintain presidential libraries. Truman believed that these endeavors were a small price for the nation to pay to support thee former occupants of the nation's highest office. Furthermore, Truman believed that presidential libraries were essential in preserving and disseminating the history of the nation's highest office. Truman's other activities including heavy involvement in partisan affairs. While he tried unsuccessfully to determine the party's presidential candidates, his involvement in the Democratic party and attendance at partisan events displayed his level of commitment to the party and his determination to play a role in its activities.

The study was undertaken: (a) to categorize the contents of educational computing articles using a taxonomy developed by Knezek, Rachlin, and Scannell (1988), (b) to examine the trends in educational computing subject matter addressed in community/junior college journals between 1977 and 1991, and (c) to identify and analyze specific characteristics of contributing authors and their employing institutions which might explain writing and publication biases.

In this study of several novels each by Barbara Pym, Fay Weldon, and Margaret Atwood, I focus on two areas: the ways in which female protagonists break out of their victimization by individuals, by institutions, and by cultural tradition, and the ways in which each author uses a structural pattern in her novels to propel her characters to solve their dilemmas to the best of their abilities and according to each woman's personality and strengths.

The purpose of this study was to determine reliability estimates of authentic assessment for fourth-grade narrative and descriptive writing samples for students with and without learning disabilities. Three types of reliability estimates were established: (a) inter-rater, (b) score stability, and (c) alternate-form. The research design involved 40 teachers, trained in holistic scoring by Education Service Centers 10 and 11 in Dallas and Fort Worth, Texas, who scored 16 writing samples. Approximately 2 weeks later the teachers rescored 8 of the same writing samples. In addition to scoring the writing samples, the teachers also completed a demographic questionnaire. The writing samples, which consisted of eight narrative and eight descriptive writings, were selected based upon teachers' holistic scores and scores from 1993 writing sample of the Texas Assessment of Academic Skills. Based upon these scores, two narrative and descriptive writings of above-average, average, and below-average writings were selected. In addition, two narrative and descriptive writing samples of students with learning disabilities in written language were selected.
