The Relation Between Selected Student Characteristics And Activity Patterns In A Required High School Physical Education Class., Karen Martha Greenockle
The Relation Between Selected Student Characteristics And Activity Patterns In A Required High School Physical Education Class., Karen Martha Greenockle
LSU Historical Dissertations and Theses
This study described the activity patterns of students in a high school fitness class and explored the structural relations between particular student characteristics and their coded exercise behavior. Exercise behavior was systematically coded during an 8-week jogging unit in 10 high school physical education classes. Additional measures of distance covered, heart rate, perceived exertion, percent of days participated, and fitness level were also collected. Although percent of time spent jogging was low (18%), with no significant gains made in cardiovascular fitness, the amount of time spent jogging, the distance covered, and fitness level were all significantly correlated (r $>$.48, …
Planning And Interactive Decision-Making In Expert Elementary Physical Education Teachers., Deborah J. Howell
Planning And Interactive Decision-Making In Expert Elementary Physical Education Teachers., Deborah J. Howell
LSU Historical Dissertations and Theses
This paper describes the planning and interactive decision making used by expert elementary physical education teachers as they developed and taught a 5 day unit on basketball dribbling. Secondly, it explores the relation between teachers' planning productivity (number of statements made) and student achievement. Expert elementary physical education teachers (N = 11) provided information regarding their thought processes during planning and interactive decision making. Planning sessions were conducted prior to each lesson with teachers using the "think aloud" technique. All instructional lessons were videotaped. Following each of the first three lessons, teachers were shown a videotape of the lesson and …
Polypeptides: Conformational Transition And Complex Formation With Catechins And Procyanidins., Luanne Faith Tilstra
Polypeptides: Conformational Transition And Complex Formation With Catechins And Procyanidins., Luanne Faith Tilstra
LSU Historical Dissertations and Theses
Theoretical explanations of the $\alpha$-helix to coil transition which employ rotational isomeric state calculations are reviewed. Recent advances in this field include the development of similar fundamentals for the intramolecular antiparallel $\beta$-sheet to coil transition. This dissertation adds to the current body of knowledge by outlining a formularization to calculate the mean square end-to-end distance, $\langle{\rm r}\sp2\rangle\sb{\rm o},$ of a homopolypeptide for the transition from random coil to intramolecular antiparallel $\beta$-sheet conformation. The formularization is translated into a computer program in the C language and values of $\langle{\rm r}\sp2\rangle\sb{\rm o}$ are calculated for a number of different statistical weights. These …
Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen
Spacing Of Repetitions And Contextual Interference Effects In Motor Skill Learning., Harry John Meeuwsen
LSU Historical Dissertations and Theses
Three experiments are reported that examined the possibility that the contextual interference effect in motor skill learning is a variation of a multiple trial spacing of repetitions effect. Specifically, the question why a non-spaced condition in a spacing of multiple trials motor learning paradigm has not produced predicted retention deficits. Subjects in all experiments learned to perform a simple motor skill in a criterion movement time. Experiments 1 and 2 examined why spacing of multiple trials did not produce expected retention performance benefits in previous spacing experiments. The results of Experiment 1 and 2 showed that the randomness of the …
A Study Of The Temperature Dependence Of Ion-Molecule Association Reactions. Halide Ion Addition To A Selected Group Of Lewis Acids., Charles Ray Herd
A Study Of The Temperature Dependence Of Ion-Molecule Association Reactions. Halide Ion Addition To A Selected Group Of Lewis Acids., Charles Ray Herd
LSU Historical Dissertations and Theses
Recent evidence has indicated that the ion-molecule association reaction BF$\sb 3$ + F$\sp -$ - thinspace- BF$\sb 4\sp -$ has both collisional stabilization and radiative stabilization pathways. Preliminary studies indicated that other boron trihalide systems (BF$\sb 3$ + Cl$\sp -$, Br$\sp -$, and BCl$\sb 3$ + Cl$\sp -$, Br$\sp -$) behave similarly. We have studied the temperature dependence of these systems in an effort to learn more about the individual rate coefficients that constitute the standard association mechanism modified to include a radiative stabilization pathway. In order to determine properties of a system which play an important role in the …
The Development Of Children's Expertise In Tennis: Knowledge Structure And Sport Performance., Sue Lynn Mcpherson
The Development Of Children's Expertise In Tennis: Knowledge Structure And Sport Performance., Sue Lynn Mcpherson
LSU Historical Dissertations and Theses
This research examined children's development of knowledge structure and sport performance in tennis. A knowledge test was designed to measure declarative knowledge and a serve and groundstroke skill test were developed to measure skill. An observational instrument was designed to record the components of performance for the serve (decision and execution) and game play following the serve (control, decision and execution). Phase 1 compared expert and novice tennis players within two age levels, 10-11 years-old and 12-13 years-old, on the individual components of tennis performance and on measures of tennis knowledge, serve skill, and groundstroke skill. Experts regardless of age …
The Effect Of Small Zwitterions And Tetraalkylammonium Ions Upon The Aggregation And Solubilization Properties Of Cationic Micellar Systems., Barry Joseph Corona
The Effect Of Small Zwitterions And Tetraalkylammonium Ions Upon The Aggregation And Solubilization Properties Of Cationic Micellar Systems., Barry Joseph Corona
LSU Historical Dissertations and Theses
The surface tension and solubilizations of a number of surfactant solutions were measured in the hope of gaining additional understanding of the structure of micelles. A number of compounds were added to micellar solutions of tetradecyltrimethylammonium bromide. These additives had structural characteristics that were similar to the structure of the cationic head group of the surfactant monomers. The additives were the quaternary ammonium halides; tetramethylammonium bromide, tetraethylammonium bromide, and tetrapropylammonium bromide, and the zwitterionic compounds; glycine, sarcosine, N,N, dimethyl glycine, and betaine. This project was initiated to ascertain whether these particular additives would actually enter the micelles and by so …
Spectroscopy Of Hexamethyldipyrromethene And Of Metallo Hexamethyldipyrromethene Complexes., Timothy Gale Fillingim
Spectroscopy Of Hexamethyldipyrromethene And Of Metallo Hexamethyldipyrromethene Complexes., Timothy Gale Fillingim
LSU Historical Dissertations and Theses
The conformations of the dipyrromethene molecule seem to control the spectral properties of its derivatives and its metal complexes. A sharply structured absorption band at 505nm that is red shifted relative to the broad structureless neutral ligand absorption band at 445nm when a weak base is added to hexamethyldipyrromethene in DMSO is inferred to be that of a negative ion. Another sharply structured absorption band at 489nm is observed after addition of a strong base to a solution of hexamethyldipyrromethene in DMSO and is inferred to be that of a different negative ion of hexamethyldipyrromethene. The two different negative ions …
