The Relation Between Selected Student Characteristics And Activity Patterns In A Required High School Physical Education Class., Karen Martha Greenockle Jan 1987

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 Jan 1987

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 …

Resort Evolution Along The Gulf Of Mexico Littoral: Historical, Morphological, And Environmental Aspects., Klaus J. Meyer-Arendt Jan 1987

Resort Evolution Along The Gulf Of Mexico Littoral: Historical, Morphological, And Environmental Aspects., Klaus J. Meyer-Arendt

LSU Historical Dissertations and Theses

The development histories of eight coastal resorts along the Gulf of Mexico littoral (Fort Myers Beach, Pensacola Beach, Dauphin Island, Grand Isle, Galveston Island, South Padre Island, Tecolutia, and Progreso) are documented to evaluate variability of temporal, spatial, and environmental aspects of resort development. Temporally, a modified S-curve model of resort evolution is offered to describe the historical development of seaside resorts, and stages of exploration, infrastructural development, and settlement expansion precede each resort's levelling off stage. The upper level of development, or level of maturation, varies among the sites, primarily as a function of demand. Resorts in high demand …

Salinity Effects On The Development And Larval Tolerance Of Five Species Of Echinoderms., Richard Allen Roller Jan 1987

Salinity Effects On The Development And Larval Tolerance Of Five Species Of Echinoderms., Richard Allen Roller

LSU Historical Dissertations and Theses

Salinity effects on the developmental rates, larval tolerances and various metabolic processes of five species of echinoderms were investigated. Development of Lytechinus variegatus (Lamarck), Strongylocentrotus droebachiensis (O. F. Muller, 1776), Strongylocentrotus purpuratus (Stimpson, 1857), Strongylocentrotus pallidus (G. O. Sars, 1871), and Pisaster ochraceus (Brandt, 1835) larvae were observed. Developmental rates and larval survival to metamorphosis of S. droebachiensis and S. pallidus varied directly with salinity and were well within the observed salinity tolerance and distributional limits for the adults. For each species, embryos and larvae at lower salinities (20, 22.5, and $25\sp{o}\!/\!\sb{oo})$ tended to develop more slowly than those at …

A Study Of Political Bias In Decisions Made By The National Labor Relations Board In Unfair Labor Practice Cases., Ronald Harold Schroeder Jan 1987

A Study Of Political Bias In Decisions Made By The National Labor Relations Board In Unfair Labor Practice Cases., Ronald Harold Schroeder

LSU Historical Dissertations and Theses

An important question has pervaded the field of labor-management relations for over fifty years: Is political bias present in the decisions rendered by National Labor Relations Board members in unfair labor practice cases? This study develops and tests a model of Board member decisions in selected unfair labor practice cases over the period 1962-1983. By studying 2147 decisions made by seventeen individual members, a relationship was found among the decisions and several variables of political party affiliations, personal background factors of members, and conditions within the procedure by which allegations of unfair labor practice violations are processed for decision. Political …

Acceptability And Effectiveness Of Group Contingencies For Improving Spelling Achievement., Timothy Lawrence Turco Jan 1987

Acceptability And Effectiveness Of Group Contingencies For Improving Spelling Achievement., Timothy Lawrence Turco

LSU Historical Dissertations and Theses

This 12-week study conceptually merged cooperative learning and group contingency approaches to classroom interventions to assess how varying task and incentive structures affect fifth-grade students' spelling achievement, social status, and perceptions of treatment procedures. The study used two groups (treatment and control group) of fifth-grade students. The students in the treatment group were actively involved with one of six group contingency procedures designed to improve spelling performances. The conditions for students in the treatment groups varied on dimensions of task structure (group or individual) and incentive structure (interdependent, dependent, or no incentive). Treatment acceptability, spelling achievement, and peer nominated social …

Influences Of Different Processing Technologies On The Properties Of Emulsion-Type Sausages., Yun-Chu Wu Jan 1987

Influences Of Different Processing Technologies On The Properties Of Emulsion-Type Sausages., Yun-Chu Wu

LSU Historical Dissertations and Theses

Emulsion-type sausages were manufactured for evaluation of microstructure, smokehouse yield, and textural characteristics with different lean sources, salt levels, casing sizes and endpoint cooking temperatures. Emulsion stability and water binding capacity of raw batters manufactured with 1, 2 or 3% salt were examined at chopping temperatures of 10, 15.5 and 21$\sp\circ$C. Frankfurters, manufactured with three sources of pork fat, were examined during a nine week storage for oxidative rancidity under different packaging conditions. Bologna from forage-finished beef had lower water, fat and total losses and a higher smokehouse yield than bologna from grain-fed beef at 1 and 2% salt levels. …

Generation, Migration, And Transportation Of Gas Contaminated Regions Of Drilling Fluid., Vicente Casariego Jan 1987

Generation, Migration, And Transportation Of Gas Contaminated Regions Of Drilling Fluid., Vicente Casariego

LSU Historical Dissertations and Theses

The control of high pressure gas encountered while drilling for hydrocarbon reservoirs is one of the more expensive and potentially dangerous problems of the oil producing industry. When the control of high pressure gas is not accomplished flow of gas from the formation to the wellbore occurs. Once detected, the gas influx is stopped by shutting-in the well. This is the first measure taken in a series of operations which are designed to bring back the well under control. These operations are referred to as well control procedures. Well control simulators are used both for evaluating well control procedures and …

Bovine Enteropathogenic Coronavirus: The Effect Of The Host Cell And Trypsin Modification On The Virus Structure, Cytopathic Expression, And Infectivity., Karen P. St. Cyr-Coats

LSU Historical Dissertations and Theses

Human rectal tumor-18 (HRT-18) cell clones 3F3, 3E3, D2, and 4B3 exhibited differences in cellular morphology in Giemsa-stained cultures and developing monolayers. Differences were evident in growth kinetics and plating efficiency of each clone. The clones produced colonies in soft agar, demonstrating anchorage independence. Cytopathic expression (CPE) including cytoplasmic vacuolization and cell fusion occurred in BCV-L9-infected clones 3F3, D2, and 3E3. Cell fusion was inapparent in clone 4B3. Bovine coronavirus strain L9 (BCV-L9) and 5 wild-type isolates replicated in HRT-18 cells, inducing cell fusion. Strain L9, exclusively, replicated in D2BFS cells, requiring trypsin to induce cell fusion. Strain L9 produced …

A Supply Response Model For Rice And Soybeans In The Mississippi Delta., David Leon Hoppenstedt Jan 1987

A Supply Response Model For Rice And Soybeans In The Mississippi Delta., David Leon Hoppenstedt

LSU Historical Dissertations and Theses

This study examines the economic sources of variation in the supply of rice and soybeans in the Mississippi Delta. As farmers alter their land allocations to various crops, they cause fluctuations in the supply of agricultural products. Traditional theory posits that acreage planted is a function of lagged prices, but does not explicitly recognize some technological constraints. One prevalent technological constraint is that the monocropping of particular crops results in a significant decrease in land productivity. The model in this study attempts to improve the specification of the technological constraint of declining soil productivity due to monocropping. Two different statistical …

Protein‐Structural Heterogeneity In A Non‐Allosteric Monomeric Insect Hemoglobin Monitored By Proton Magnetic Resonance Spectroscopy, David H. Peyton, R. Krishnamoorthi, Gerd N. La Mar, Klaus Gersonde, Kevin M. Smith, Daniel W. Parish Jan 1987

Protein‐Structural Heterogeneity In A Non‐Allosteric Monomeric Insect Hemoglobin Monitored By Proton Magnetic Resonance Spectroscopy, David H. Peyton, R. Krishnamoorthi, Gerd N. La Mar, Klaus Gersonde, Kevin M. Smith, Daniel W. Parish

Faculty Publications

Proton NMR has revealed two modes of structural heterogeneity in the monomeric hemoglobin I of Chironomus thummi thummi, CTT I; rotational disorder caused by a 180° rotation of the heme about the α, γ‐meso axis (primary heterogeneity), which varies for each preparation or reconstitution of this hemogobin, and a ‘silent’ amino acid replacement [Thr/Ala exchange in position 98(FG4)] in the vicinity of the heme group, which is invariant under all experimental conditions. The heme rotational disorder (primary heterogeneity) can be removed by reconstitution of CTT I with the symmetrical protoheme III. The secondary splitting is not affected; the ratio of …

Mechanism Of Attachment Of Swarm Cells Of Thiothrix Nivea., J. M. Larkin, R. Nelson Jan 1987

Mechanism Of Attachment Of Swarm Cells Of Thiothrix Nivea., J. M. Larkin, R. Nelson

Faculty Publications

Swarm cells of Thiothrix nivea were found to possess a group of fimbriae at one pole. The other pole either was bare or possessed from one to three fimbriae. By using this polarity as a marker, it was found that the initial step in attachment of swarm cells involves the fimbriated pole and that this initial step is followed by the production of holdfast material.

On Weakly Symmetric Graphs Of Order Twice A Prime, Ying Cheng, James Oxley Jan 1987

On Weakly Symmetric Graphs Of Order Twice A Prime, Ying Cheng, James Oxley

Faculty Publications

A graph is weakly symmetric if its automorphism group is both vertex-transitive and edge-transitive. In 1971, Chao characterized all weakly symmetric graphs of prime order and showed that such graphs are also transitive on directed edges. In this paper we determine all weakly symmetric graphs of order twice a prime and show that these graphs too are directed-edge transitive. © 1987.

A Characterization Of The Ternary Matroids With No M(K4)-Minor, James G. Oxley Jan 1987

A Characterization Of The Ternary Matroids With No M(K4)-Minor, James G. Oxley

Faculty Publications

Brylawski identified the class of binary matroids with no minor isomorphic to M(K4) as being the class of series-parallel networks. From this he deduced that, for all such matroids M, the critical exponent c(M; 2) is at most 2. He also conjectured that a similar result is true over all finite fields GF(q). This paper examines the classes of ternary and GF(4)-representable matroids with no M(K4)-minor. The main result characterizes the former class by showing that, with one exception, the only non-trivial 3-connected members of this class are whirls or minors of the Steiner system S(5, 6, 12). This characterization …

Some Results In Discontinuous Fields And Wave Propogation, R. Estrada, R. P. Kanwal Jan 1987

Some Results In Discontinuous Fields And Wave Propogation, R. Estrada, R. P. Kanwal

Faculty Publications

We present various applications of recently developed techniques which are an interplay between the differential geometry and the theory of distributions. We apply them to the microlocal theory, derive the general order transport equations for the strength of wave fronts, obtain the values of the jumps of the general Nth-order derivatives of the harmonic functions across the potential layers, and present the explicit formulas for an arbitrary order derivative of functions of the radial distance r. © 1987.

Continuous Pythagoras Numbers For Rational Quadratic Forms, Charles N. Delzell Jan 1987

Continuous Pythagoras Numbers For Rational Quadratic Forms, Charles N. Delzell

Faculty Publications

We introduce the concept of the continuous Pythagoras number Pc(S) of a subset S of a commutative topological ring to be, roughly, the least number m ≤ ∞ such that the set of sums of squares of elements of S can be represented as sums of m squares of elements of S, by means of m continuous functions. Heilbronn had already shown that Pc(Q) = 4. Letting Ln(F) be the set of linear n-ary forms over the field F, we show that Pc(Ln(R)) = n. We then allow continuously varying nonnegative rational "weights" on the m square summands. If these …

Use Of Linear Semen Quality Score For Classification And Decision Making In Evaluation Of Individual Ejaculates Of Holstein Bulls, J. E. Chandler, R. W. Adkinson, J. W. Smith, A. M. Saxton

Faculty Publications

Four hundred seven ejaculates from 15 Holstein bulls collected from December 1984 to June 1985 were evaluated postthaw for viability characteristics (percent progressive motility at 0 h and after 3 h at 37°C incubation, percent intact acrosomal membrane after 3 h at 37°C incubation) and abnormal morphological characteristics [percent head (primary), midpiece, and tail (secondary) abnormalities]. Weighting coefficients for combining viability and abnormality characteristics were generated from between-bull and within-bull variance and covariance matrices. Two hundred ninety-eight additional ejaculates collected from July 1985 to February 1986 were added. Linear quality scores for 705 ejaculates (24 bulls) were the sum of …

Interdependent Group-Oriented Contingencies: Effects Upon Collateral Behaviors., Verdi Rountree Lethermon Jan 1987

Interdependent Group-Oriented Contingencies: Effects Upon Collateral Behaviors., Verdi Rountree Lethermon

LSU Historical Dissertations and Theses

Two interdependent group-oriented contingency (g-o-c) systems to improve academic behavior were compared to a no treatment control group. Additionally, the two interdependent group-oriented contingency systems were compared to each other regarding their effects on several collateral behaviors (classroom behavior, social interactions and peer sociometric ratings). Six fourth and fifth grade classes (126 students) were randomly assigned to three experimental conditions. The first treatment group (positive g-o-c) was an interdependent group-oriented contingency system which reinforced overall science performance at or better than a level of 90%. The second treatment group (negative g-o-c) was also an interdependent group-oriented contingency system which discouraged …

Bionomics Of The Sugarcane Borer, Diatraea Saccharalis (F.), In Sweet Sorghum, Sorghum Bicolor (L.) Moench., Billy Wayne Fuller Jan 1987

Bionomics Of The Sugarcane Borer, Diatraea Saccharalis (F.), In Sweet Sorghum, Sorghum Bicolor (L.) Moench., Billy Wayne Fuller

LSU Historical Dissertations and Theses

Economic impact studies revealed that the sugarcane borer, Diatraea saccharalis (F.), reduced sweet sorghum yield of total sugars up to 46% in artificially infested field trials. A significant relationship was found between D. saccharalis damage and yield loss that indicated an economic injury level of 10% bored internodes. Stalk weight, percent sucrose, and total sugars were negatively correlated to D. saccharalis damage; and increased fiber content was positively correlated to percent bored internodes. Information from damage levels, along with survival records, indicated that the economic threshold was reached when approximately 5% of the sweet sorghum plants contained small D. saccharalis …

The Public Reading Career Of Agnes Moorehead: An Investigation Of Her Theory And Practice., Orville Leon Perkins Jan 1987

The Public Reading Career Of Agnes Moorehead: An Investigation Of Her Theory And Practice., Orville Leon Perkins

LSU Historical Dissertations and Theses

Agnes Moorehead worked as a professional actress for forty-five years. She was employed in all the major entertainment fields of her time--theatre, vaudeville, radio, film, television and the recording industry. A significant reason for this almost constant employment was Moorehead's career as a public reader of literature. The purpose of this study is twofold. First, it seeks to document Moorehead's public reading career with emphasis upon her solo performances of literature and in so doing to provide an investigation of those people and events that most influenced her success as an oral reader. The second purpose is to postulate Moorehead's …

A Seasonal And Ontogenetic Examination Of The Reproductive Biology Of Pseudoplusia Includens (Walker)., Linda Jean Mason Jan 1987

A Seasonal And Ontogenetic Examination Of The Reproductive Biology Of Pseudoplusia Includens (Walker)., Linda Jean Mason

LSU Historical Dissertations and Theses

Laboratory observations on the mating behavior of soybean loopers, Pseudoplusia includens (Walker), indicated a calling pattern that was highly variable both within individual females over time and among individuals. However, some trends were apparent. The onset of calling showed temporal advancement over the first three nights of calling after adult emergence; the duration of calling showed a temporal advancement during the first six nights, while the termination of calling receded over the same period then reversed its trend. The majority of females initiated calling three nights following emergence while maximum percent calling was observed around five hours after the onset …

Rumors, Runaways, Revolt!: An Overview Of Slave Unrest In Colonial And Territorial Louisiana, Morris Lewis Witten May 1986

Rumors, Runaways, Revolt!: An Overview Of Slave Unrest In Colonial And Territorial Louisiana, Morris Lewis Witten

LSU Historical Dissertations and Theses

A major problem in the historiography of slavery in Louisiana is the reliance of too many historians on the early narratives. Because they lack scholarly citations and often contain erroneous information, evaluations of slavery based on these early sources are often inaccurate. By examining four periods of slave unrest in colonial and territorial Louisiana — the 1829-1830 conspiracy known as "Samba’s Revolt," the 1795 conspiracy at Pointe Coupee Parish, the incident of runaway slaves at Natchitoches in 1804, and the 1811 uprising in St. Charles Parish — one can determine how errors in fact, once they enter the history of …

Jurors' Decisions In A Simulated Trial Of The Pms Defense: Background Characteristics And Attitudes Toward Menstruation., Marjorie Carole Donohoe Jan 1986

Jurors' Decisions In A Simulated Trial Of The Pms Defense: Background Characteristics And Attitudes Toward Menstruation., Marjorie Carole Donohoe

LSU Historical Dissertations and Theses

This mock jury study assessed the feasibility of utilizing Premenstrual Syndrome (PMS) as a substantive defense in a capital case. One hundred-eighty mock jurors were asked to render judgments in identical cases of spouse murder with one of three defenses: (1) temporary insanity due to PMS; (2) temporary insanity with a reported history of psychiatric treatment; and (3) temporary insanity brought about by extreme emotional trauma. Results indicated that mock jurors rejected an insanity defense for the PMS defendant. Jurors were more willing to render an NGRI (Not Guilty by Reason of Insanity) verdict for the defendant with a documented …

An Empirical Investigation Of The Comparability Of Reported Earnings Per Share Under Accounting Principles Board Opinion No. 15., Suzanne Resi Pinac-Ward Jan 1986

An Empirical Investigation Of The Comparability Of Reported Earnings Per Share Under Accounting Principles Board Opinion No. 15., Suzanne Resi Pinac-Ward

LSU Historical Dissertations and Theses

Earnings per share (EPS) is considered by many to be one of the most important summary indicators presented in the financial statements. Many financial statement users rely on EPS as the most important single measure of corporate performance. Previous empirical evidence suggests that a strong link exists between EPS changes and stock price changes. The objective of this study was to determine if the provisions of APB 15 provide for consistent reporting of comparable EPS figures across preparers of financial statements. The application of alternative interpretations of provisions of APB 15 has the potential to produce materially different EPS figures. …

The Measurement Of Change In Performance Appraisal Rater Training., Mitzi Desselles Svoboda Jan 1986

The Measurement Of Change In Performance Appraisal Rater Training., Mitzi Desselles Svoboda

LSU Historical Dissertations and Theses

The concepts of alpha, beta, and gamma change (Golembiewski, Billingsley, & Yeager, 1976) were used to assess the effects of rater error training (RET) and frame of reference training (FOR) on performance evaluations. Two studies were conducted using students as raters; Study 1 was a laboratory study in which raters evaluated managerial performance in the form of the Borman (1979) videotapes. Study 2 provided a field replication of the methodology with students rating actual instructor effectiveness. In both investigations RET and FOR were found to create significant concept redefinition (gamma change). In addition, the different procedures for assessing alpha, beta, …

Tolerance, Bioenergetics And Biochemical Composition Of The Blue Crab, Callinectes Sapidus Rathbun, Exposed To The Water-Soluble Fraction Of South Louisiana Crude Oil., Shiao Yu Wang

LSU Historical Dissertations and Theses

The tolerance, bioenergetics, growth, molting frequency and biochemical composition of juvenile blue crabs, Callinectes sapidus, exposed to the water-soluble fraction of South Louisiana crude oil were determined during a 21-d exposure period. Blue crabs were highly tolerant to petroleum hydrocarbons; the LC50 was 3927 ppb on day 21. Rates of energy intake decreased with increasing hydrocarbon concentration. Although energy expenditure rates of crabs exposed to 2504 ppb were not significantly higher than that of control crabs, they were significantly higher than those of crabs exposed to 820 and 1476 ppb. The resulting decrease in scope for growth was thus due …

A History And Analysis Of Selected National Urban League Discourse, 1910-1985., Dennis D. Cali Jan 1986

A History And Analysis Of Selected National Urban League Discourse, 1910-1985., Dennis D. Cali

LSU Historical Dissertations and Theses

This dissertation is a critical analysis of selected annual conference addresses of National Urban League (NUL) executive directors. It may be regarded as a "movement study" inasmuch as it traces the conceptualization of an idea, equality, from 1910 to 1985. Richard Weaver's philosophy, theory, and critical methodology of rhetoric provide the analytical framework by which this study was conducted. Specifically Weaver's hierarchy of arguments, which may be taken as a model of his philosophy and theory, served as this dissertation's research tool. The hierarchy includes argumentation from four perspectives, ranking from ideal to base: genus, similitude, cause-effect, circumstances. The dissertation …
