Fifty three male subjects were used to determine whether the cross-over step or the side step was the most effective technique in starting and traveling a distance of 15 feet to the right and/or left. After determining which method was best the total movement response time was broken down into reaction time and movement time in order to determine where the difference existed in the two methods of lateral movement. The relationship between hip width, leg length, and weight to total movement response time and the relationship between movement time and reaction time were also measured. / A Dekan Automatic Performance Analyzer was used to measure reaction time, speed of movement, and total movement response time. Each subject performed the total movement response time test a total of 10 times, using the cross-over step five times, and the side-step five times. Each subject performed the speed of movement test a total of 10 times, using the cross-over step five times, and the side-step five times. The time recorded for each trial, and the mean of the five trials with each style represented each subject's time for that particular running style. Reaction time was determined for each subject by subtracting each subject's movement time from his total movement response time. / The t test was employed to test for significance of the difference between the cross-over step and the side-step in total movement response time, speed of movement, and reaction time. The Pearson Product-moment correlation technique was used to determine the relationship between selected anthropometric measurements and total movement response time in the cross-over step and side-step. The Pearson Product-moment correlation technique was also employed to determine the relationship between reaction time and speed of movement. / Statistical treatment of data indicated significant difference between the cross-over step and side-step in total movement response time in favor of the cross-over step. When comparing the speed of movement of the cross-over step and side-step, the cross-over step was found to be significantly faster. In comparing the reaction time of the cross-over step and side-step no significant difference was found. According to the results of this study, the cross-over step method of lateral movement was faster than the side-step method for use by volleyball players. Also, the finding indicated that the cross-over step superiority to the side-step method was due to the speed of movement in these two styles of lateral movement. / The Pearson Product-moment correlations obtained between the anthropometric measurement and total movement response time were low and not significant except for leg length and total movement response time in the side-step. The correlations obtained between movement times and reaction times indicated a significant correlation between movement time and reaction time in the side-step, but not in the cross-over step. / Source: Dissertation Abstracts International, Volume: 41-01, Section: A, page: 0156. / Thesis (Ph.D.)--The Florida State University, 1980.

A theoretical method of analyzing dynamics of laser excitation of molecular systems is presented. We use the eigenstates and eigenenergies of an effective Hamiltonian to solve directly for the time development operator matrix elements. We analytically solve for the transition probability amplitude matrix elements for a two-level system. We compare these results with computer simulations as a check on our software. We then apply our method computationally to the study of; three-level system dynamics, interaction of a single state with a manifold of 16 states (in the 'picket fence' limit), interaction of two states through a common continuum, and laser excitation of a molecular system represented by six levels. We predict the possibility of observing several phenomena dependent on the radiative intensity; radiative decoupling of radiationless transitions, optically induced radiationless transitions, intensity dependent photo-chemistry, and optical pumping of phosphoresence. / Source: Dissertation Abstracts International, Volume: 41-03, Section: B, page: 0977. / Thesis (Ph.D.)--The Florida State University, 1980.

The purpose of this research was to study and compare the academic achievement of current athletes to matched nonathletes and former athletes. Comparisons of the current athletes, within their sport teams and by their sex, were also conducted. / College transcripts were analyzed for a total of 1,033 subjects to determine the number of hours attempted and passed in Basic Studies, major fields of study, and overall. Accumulative and yearly GPAs, yearly and transfer credits, length of time in school, and attrition rates were also calculated for each subject. The transcripts of all athletes were additionally analyzed to determine the extent of their academic achievement during their seasons of sport. When available, the high school GPAs and SAT scores were used in covariant analyses. / The SPSS computer programs for analysis of variance, analysis of covariance, one-way analysis of variance with an LSD post-hoc test and the Student's t-test were utilized to analyze the data. Fourteen null hypotheses were tested for statistical differences. / The results indicated no significant differences in the academic progress of current athletes and matched nonathletes. Current female athletes had significantly higher GPAs than their male counterparts. The current athletes on the various sports teams differed significantly in their patterns of course work, but showed no differences in their GPAs. Former athletes were scholastically superior to the current athletes on most variables studied. / Source: Dissertation Abstracts International, Volume: 42-10, Section: A, page: 4354. / Thesis (Ph.D.)--The Florida State University, 1981.

Theoretical studies and numerical experiments of the subarctic front are conducted. The theoretical side of this research encompasses the determination of a stability criterion and the role friction plays as a dissipative mechanism. In the first case study, it is established that if the difference between the phase speed of the perturbation and the mean long-front geostrophic flow is greater than a certain value, the subarctic front is stable everywhere. In the other case study, it is proved that the time scale of dissipation is sufficiently large to neglect horizontal friction. While the effect of the westerly winds causes a southward shift of the front, the effect of a negative curl shows convergence at the front. This convergence strongly favors frontogenesis. / It is established that the phase speed of the first baroclinic mode is larger in a numerical model where a constant density jump between layers is employed. Thus, a smaller time scale is required to avoid the numerical instability caused by the violation of the CFL criterion. A numerical four-layer hydrodynamical model is implemented to investigate the role the atmosphere exerts on the dynamics of the subarctic front. / The salient features at the wake of a strong cyclone can be summarized as follows: (i) upwelling of 20 meters of the four interfaces occurs; (ii) the water remains upwelled for several weeks; (iii) the e-folding time scale of the vertical oscillations induced by the storm's passage is of the order of 10 days; (iv) a region of relative maximum convergence is observed in the lower layers below a region of relative maximum upwelling in the upper layer; and (v) the long and cross-front velocity fields are in quadrature in time, with the cross front velocity lagging the long front velocity. / With the exception of the cyclone's case, it is established that the effects of the atmospheric wind forcing are confined to the upper layer. These results are supported by oceanic observations. Finally, it is also proved that the response of the front to the atmospheric momentum transfer is independent of the initial form of the subarctic front. / Source: Dissertation Abstracts International, Volume: 42-01, Section: B, page: 0121. / Thesis (Ph.D.)--The Florida State University, 1981.

The purpose of the investigation was to study, by the use of a questionnaire designed by the investigator, the involvement of Blacks in women's athletics in member institutions of the Association of Intercollegiate Athletics for Women (AIAW). Two hundred and five of the 1978-79 member institutions participated in the study. Nine specific problems were analyzed descriptively; nine hypotheses were analyzed statistically by the Chi Square test for two independent samples and the Yates Correction Chi Square. / Of the 205 participating schools, 111 (54%) were classified as private institutions and 94 (46%) were classified as state institutions. Ninety-seven (47%) were classified as colleges and 108 (53%) were classified as universities. Eleven (5%) institutions were classified as predominantly Black and 194 (95%) were classified as predominantly Nonblack. Sixty-one schools (30%) were categorized Division I institutions, 78 (38%) were Division II, and 66 (32%) were Division III. All nine AIAW regions were represented in the study. / Results indicated that black female athletes represent 8% of the 13,398 collegiate female athletes, and are represented by a greater number on basketball teams and a greater percentage on track and field teams than on 12 other selected sports. Forty-eight percent of the 8% receive some type of athletic scholarship; this represents 11% of the total number of athletic scholarships awarded to females. Black female basketball players received the greatest number; 62% were recipients. Track and field squads had 44% of the black females on athletic scholarship. / Five percent of the head coaches and 8% of the assistant coaches were black; this 1978-79 figure represents an increase of 35% from the 1973-74 total. In other administrative positions, blacks occupied 7% of the 1978-79 total. / Eleven sports were offered by more colleges in 1978-79 than in 1973-74. The status of two sports remained the same while one, badminton, experienced a decrease in popularity. The greatest growth was evidenced in slow pitch softball but more schools maintained a basketball team than any other team. / The percentage (8%) of black female athletes within these institutions was significantly lower than the percentage of black female undergraduate students enrolled in higher education. There appeared to be a significant difference in the number of black and nonblack female athletes who occupied the battery, infield, and outfield positions in softball. There was also a significant difference in the number of black and nonblack female athletes who occupied the sprint/hurdle, distance, middle distance, jumping, and throwing positions in track and field. A significant difference was found in the number of black and nonblack female athletes who played the setter, spiker, and defensive specialist positions in volleyball. There was a significant difference in the number of black and nonblack female athletes who were categorized in the frontline, backs, and goalie positions in field hockey. Results indicate there was no significant difference in the number of blacks and nonblacks who occupied the backcourt, playmaker, and frontline positions in basketball. As a result of this study, it is recommended further research be conducted to determine the status and involvement of Blacks in women's athletics in the next few years. / Source: Dissertation Abstracts International, Volume: 41-07, Section: A, page: 2997. / Thesis (Ph.D.)--The Florida State University, 1980.
