The Effects Of Curriculum Tracking On Women's Occupational Outcomes: A Test Of The Correspondence Principle., Leroy Allen Furr
The Effects Of Curriculum Tracking On Women's Occupational Outcomes: A Test Of The Correspondence Principle., Leroy Allen Furr
LSU Historical Dissertations and Theses
In recent years, Marxist theories have challenged the traditional, meritocratic perspective dominant in the sociology of education. The meritocracy assumes that schools, like the larger society, are based on the premise of equal opportunity; success in school is the result of hard work and good grades, which lead to good jobs and good incomes. Bowles and Gintis, among other revisionists, disagree arguing that the structure of education, sorting students into segregated, hierarchical curriculum tracks, mirrors the structure of the capitalist workplace and reproduces the existing class system such that the most advantaged persons and groups continue to fare well while …
Studies On The Molecular Cloning Of A Gene For Beta-Glucosidase From A Bacillus Cereus/Cellulomonas Sp. Hybrid Bacterium Derived Through Protoplast Fusion., Eun Soo Han
LSU Historical Dissertations and Theses
A (beta)-glucosidase gene was cloned from a cellulolytic bacterium, which was obtained by hybrid-formation between Bacillus cereus and a Cellulomonas sp. through protoplast fusion, into Escherichia coli plasmid pBR322 using recombinant DNA techniques. E. coli strain transformants of JM83 harboring this cloned plasmid were able to utilize cellobiose as a carbon source. (beta)-glucosidase activity was assayed in these cells by P-nitrophenyl (beta)-D-glucopyranoside (PNPG) hydrolysis. Hybridization of the cloned DNA fragment with DNA from the hybrid organism was performed by Southern transfer (92) and DNA/DNA dot blot procedures. The hybridization data strongly suggested that the DNA cloned into pBR322 was from …
The Effect Of Educational Technology Variables On Elementary Education Student Achievement (Instructional Materials, Educational Media)., Deborah Scruggs Miller
The Effect Of Educational Technology Variables On Elementary Education Student Achievement (Instructional Materials, Educational Media)., Deborah Scruggs Miller
LSU Historical Dissertations and Theses
The purpose of this study was to determine whether educational technology variables differentiate between "effective" and "ineffective" elementary schools. It was hypothesized that "effective schools" use educational media in instruction more frequently than "ineffective schools". It was also expected that "effective schools" use educational media in qualitatively superior ways to "ineffective schools". In addition, it was predicted that "effective schools" would have better prepared teachers in educational media and teachers with more years of teaching experience than "ineffective schools". The sample consisted of fourteen elementary schools located in 12 school districts throughout Louisiana. Each school was determined to be either …
Benthic Microfloral Production On The West And Gulf Coasts Of The United States: Techniques For Analyzing Dynamic Data (Entropy Data Analysis)., Gary Paul Shaffer
Benthic Microfloral Production On The West And Gulf Coasts Of The United States: Techniques For Analyzing Dynamic Data (Entropy Data Analysis)., Gary Paul Shaffer
LSU Historical Dissertations and Theses
The objective of this study was to compare benthic microfloral production on the west and gulf coasts of the U.S.A., and to determine what factors govern that production. Intensive, month long field studies were conducted at two sites in a salt marsh lagoon (Mugu Lagoon) in southern California and at two sites in a shallow water estuary (Barataria Estuary) in southwest Louisiana. For both studies, fluctuations in production during a single month approximated those measured previously over an entire year: daily production varied from 0 to 1500 mg C (.) m('-2). A comparison was made between the sources of error …
Moral Evaluation: An Investigation Of Developmental Patterns In The Use Of Cognitive Algebra (Information Integration)., Anthony Herman Speier Jr
Moral Evaluation: An Investigation Of Developmental Patterns In The Use Of Cognitive Algebra (Information Integration)., Anthony Herman Speier Jr
LSU Historical Dissertations and Theses
Information integration theory suggests that differences in the moral judgments of children and adults is an example of a development process of information integration where younger children employ a unidimensional integration rule, and older children and adults employ multidimensional integration rules. Studies that utilize the information integration approach involve single-episode stories in which two or three levels of intention and consequence story cues are manipulated in a within-subjects factorial design. The present study manipulated two sources of information about the story protagonist, as well as information about his intentions and the consequences. The four variables manipulated were: (a) personal goodness …
The Effect Of Temperature And Humidity Stress On Plasma Progesterone, Luteinizing Hormone And Cortisol Profiles Following Cloprostenol Injection In Cycling Holstein Cows In A Controlled Environment (Environmental Physiology, Reproduction, Prostaglandins)., Anandarajah Sri Kanda Kumar
The Effect Of Temperature And Humidity Stress On Plasma Progesterone, Luteinizing Hormone And Cortisol Profiles Following Cloprostenol Injection In Cycling Holstein Cows In A Controlled Environment (Environmental Physiology, Reproduction, Prostaglandins)., Anandarajah Sri Kanda Kumar
LSU Historical Dissertations and Theses
The effect of heat stress on plasma profiles of progesterone, luteinizing hormone (LH) and cortisol was evaluated following cloprostenol (500 (mu)g) induced luteolysis in lactating and non-lactating cows in a controlled environment. Another experiment was conducted to evaluate the effect of heat stress on the superovulatory response in lactating cows. The plasma progesterone, LH and total estrogen concentrations were not altered by heat stress (P > 0.05) when the average rectal temperatures of both lactating and non-lactating cows were raised to 39.83(DEGREES)C (103.7(DEGREES)F). However, plasma cortisol was significantly suppressed (P < 0.05) during heat stress. Luteolysis was followed by a preovulatory LH surge in all cows following cloprostenol and thus heat stress did not appear to alter the responsiveness of the corpus luteum to cloprostenol and the factors which regulate the hypothalamic control of LH release. Preovulatory LH peaks were preceded by total estrogen peaks and therefore heat stress did not appear to alter the positive feedback of estrogens from the preovulatory follicles to release LH from the pituitary gland. The magnitude of the diurnal variation of cortisol was higher during lower stress. LH peaks were seen irrespective of cortisol concentrations during both higher and lower stress treatments. However, LH peaks coincided with those of cortisol and total estrogens during lower stress treatments in both lactating and non-lactating cows. An altered diurnal variation in rectal temperatures was seen following LH peaks during lower stress. Fifteen transferable embryos were recovered during lower stress (15/34 or 44%) compared to one transferable embryo (1/4 or 25%) during higher stress (P > 0.05) in the superovulation study. Thus it appears that heat stress …
The Status Of Modal Counterpoint In Selected Colleges And Universities In The United States And A Survey Of Selected Modal Counterpoint Textbooks (Sixteenth-Century)., John Peter Senick
The Status Of Modal Counterpoint In Selected Colleges And Universities In The United States And A Survey Of Selected Modal Counterpoint Textbooks (Sixteenth-Century)., John Peter Senick
LSU Historical Dissertations and Theses
A questionnaire was devised to determine the general status of modal counterpoint classes in selected colleges and universities in the United States and to discover the most-used modal counterpoint textbooks, specifically those exhibiting the direct approach; it was sent to 152 NASM approved schools, and 117 (76.97%) responses were obtained. Information was requested about the types of counterpoint classes offered, the respondents' ratings of the modal counterpoint texts they use, teaching aids and techniques, and ways in which modal counterpoint is included in the music curriculum. Ninety-one (77.8%) of the 117 responding institutions included modal counterpoint in their course offerings. …
Extreme Elements In Semigroups (Quasiorders, Green's)., Carol Esther Collins
Extreme Elements In Semigroups (Quasiorders, Green's)., Carol Esther Collins
LSU Historical Dissertations and Theses
We study the elements of a semigroup which are minimal or maximal with respect to Green's quasiorders. Part 1 begins with a preliminary review. The sets of minimal elements are characterized in terms of minimal ideals. We discuss the relationship between the min set of a semigroup and the min set of a subsemigroup. The sets of maximal elements are characterized, and it is shown that these sets do not necessarily satisfy any inclusion relationships to each other. We discuss the max sets of subsemigroups and product semigroups. Conditions are given under which the max sets and min sets can …
A Horizontally Reconfigurable Architecture For Extended Precision Arithmetic (Parallel Computing, Condition Codes Factoring)., Donald Mark Chiarulli
A Horizontally Reconfigurable Architecture For Extended Precision Arithmetic (Parallel Computing, Condition Codes Factoring)., Donald Mark Chiarulli
LSU Historical Dissertations and Theses
A special computer for high-precision arithmetic and parallel processing which features an ALU that is dynamically reconfigurable under program control has been designed and a prototype machine constructed. The 256-bit ALU consists of eight 32-bit slices each of which has its own ALU operation code in each microinstruction. The slices can remain logically separated from each other, or can be dynamically connected to either or both of their neighbors under control of a segment control code that is part of each microinstruction. The result is a unique parallel architecture which provides real parallelism to user programs at the instruction level …

Fate And Transport Of Low-Ph Hazardous Materials After Deep Well Disposal., Winton G. Aubert
LSU Historical Dissertations and Theses
The ultimate fate and chemical kinetics of low-pH hazardous wastes after deep well injection were studied. Two experimental approaches were taken. Chemical kinetics of reactions involving acids and typical formation clays was studied using a batch reaction scheme. The effects of reactions involving flowing acidic waste streams and disposal formations were characterized using sand packs of length one foot, four feet, and twenty feet. A numerical ground water flow simulator was used to model the interactions of flowing acidic wastes with linear sand packs and with a hypothetical waste disposal system. Reaction rate coefficients and activation energies were determined for …
Spectroscopic Studies Of Bacterial Iron-Sulfur Proteins (Electron Paramagnetic Resonance, Magnetic Circular Dichroism)., Deborah Ellen Bennett
Spectroscopic Studies Of Bacterial Iron-Sulfur Proteins (Electron Paramagnetic Resonance, Magnetic Circular Dichroism)., Deborah Ellen Bennett
LSU Historical Dissertations and Theses
Iron-sulfur proteins play a vital role in metabolism; mediating such life-sustaining processes as aerobic and anaerobic respiration, nitrogen fixation, and photosynthesis. This work employs low temperature magnetic circular dichroism (MCD), electron paramagnetic resonance (EPR), and UV-visible spectroscopy to characterize the iron-sulfur clusters of the following bacterial proteins: Azotobacter vinelandii ferredoxinI, Thermus thermophilus ferredoxin, Escherichia coli nitrate reductase and the rubredoxin and ferredoxin from Clostridium pasteurianum. Novel 3Fe-xS clusters were identified in A. vinelandii FdI, T. thermophilus Fd, ferricyanide treated C. pasteurianum Fd, and E. coli nitrate reductase. The uniformity of the magnetic and electronic properties of these clusters in both …

Dyadic Ramification In Quartic Algebraic Number Fields., Stella Roberson Ashford
Dyadic Ramification In Quartic Algebraic Number Fields., Stella Roberson Ashford
LSU Historical Dissertations and Theses
This dissertation is concerned with dyadic ramification in quartic number fields E. If f(x) is a defining polynomial for E, then E (TURNEQ) IQ x /(f(x)). The problem is to decide whether or not 2 ramifies in E, in terms of the coefficients of f(x). In this dissertation, this problem is. studied when f(x) is an irreducible quartic trinomial. That is, f has one of the forms (UNFORMATTED TABLE FOLLOWS). (1) f(x) = x('4) + cx + d. (2) f(x) = x('4) + cx('2) + d c,d in ZZ. (TABLE ENDS). (any irreducible trinomial can be reduced to one of …
Estimation Of Nonlinear Frontier Functions And Efficiency Measurements For Airframe Production Programs., Banani Dhar
Estimation Of Nonlinear Frontier Functions And Efficiency Measurements For Airframe Production Programs., Banani Dhar
LSU Historical Dissertations and Theses
This research examines measures of economic efficiency in aircraft production. In particular, a type of nonlinear frontier estimation is contrasted with more traditional methods for estimating a dynamic cost function. This cost function is grounded in economic theory, and it is consistent with our knowledge of the aircraft production process. The model includes the effects of both learning and production rate on total program costs. Our model differs from more traditional cost specifications in that we make no attempt to measure production rate. Our model links direct labor requirements to fixed delivery schedules, under the assumption that the firm attempts …
Computer-Aided Analysis Of Formation Pressure Integrity Tests Used In Oil Well Drilling., Mauricio Aguiar Almeida
Computer-Aided Analysis Of Formation Pressure Integrity Tests Used In Oil Well Drilling., Mauricio Aguiar Almeida
LSU Historical Dissertations and Theses
Formation pressure-integrity tests or leak-off tests have been increasingly performed throughout the world. The test is performed primarily to verify how much pressure can be applied to the formation below the bottom of casing, and to test the cement job sheath around the outside of the casing. The initial design of the various casing strings to be cemented in the well depends heavily on the predicted fracture-pressure curve. If this predicted curve is not verified by the test, the casing plan will have to be changed. Thus, verifying formation fracture-pressure during drilling is of great importance. However, the lack of …

The Fricative Sound Source Spectrum Derived From A Vocal Tract Analog., Lawrence Edward Zagar
LSU Historical Dissertations and Theses
The applications of speech synthesis for computer voice response and speech analysis present the need for highly intelligible and natural synthesized speech. In order to improve the synthesis of fricative and related sounds, the use of simple models for the source spectrum of fricative sounds is investigated. The investigation is based on the use of a vocal tract analog and experimental measurements. Measurements of the sound pressure spectra of fricative consonants are made. Simple sound pressure measurements and measurements based on the technique for measuring intensity are utilized. The fricatives studied are /f/, /th/, /s/, /sh/, and /h/. Fricative sound …
Amine Removal From Aqueous Process Streams By Ligand Exchange., Wayne Bernard Bolden
Amine Removal From Aqueous Process Streams By Ligand Exchange., Wayne Bernard Bolden
LSU Historical Dissertations and Theses
Amines in aqueous, process feed or effluent streams can cause contamination problems. Ligand exchange demonstrates the potential to remove amines from these process streams. In ligand exchange, a complexing solute is removed from solution as it covalently bonds to a metal ion held on cation exchange resin. Previous work has shown copper(II)-carboxylic acid resin to be a suitable metal-resin exchange sorbent. The results of a research program are presented showing the applicability of ligand exchange to an amine removal operation. This study includes experimental determination of equilibrium relationships and diffusion coefficients. These parameters have been used to mathematically model ligand …

The Topological Information Retrieval System And The Topological Paradigm: A Unification Of The Major Models Of Information Retrieval., Steven C. Cater
LSU Historical Dissertations and Theses
There are three topics discussed in this work. The first topic is an investigation of the topological properties of the p-norm model of Salton, Fox, and Wu. It is shown that certain properties of the p-norm model that one would expect to hold, given the topological origin of the model, do not in fact hold. These properties include the ability to change the query by changing p, and the ability to adequately separate documents. Since these properties do hold in the model as actually constructed, it must be that the properties do not follow from the topological origin of the …
The Relationship Between Teachers' Perceptions Of Principals' Job Performance, Teacher Job Satisfaction, Principal Influence And School Outcomes., John Aaron Jackson
The Relationship Between Teachers' Perceptions Of Principals' Job Performance, Teacher Job Satisfaction, Principal Influence And School Outcomes., John Aaron Jackson
LSU Historical Dissertations and Theses
This study investigated the relationship between principals' instructional leadership behavior and school effectiveness. In the conceptual model tested, certain school context variables, teachers' job satisfaction and teachers' willingness to accept principals' influence in the instructional realm, were viewed as mediating the relationship between principals' behavior and school outcomes. From this perspective, principals' instructional leadership behavior was seen as being indirectly related to school outcomes by its impact on these mediating variables. For the purposes of this study, teachers' job satisfaction, teachers, willingness to accept principals' professional advice and teachers' perceptions of principals' effectiveness as instructional leaders served as independent variables. …

Olfactometric In Situ Soil Exploration: Development Of The Electro-Odo-Cone., Mohammad Mohammadi
LSU Historical Dissertations and Theses
The suitability of the electro-odo-cell (EOC) for detection of organic chemical contaminants in ambient air and soil strata was investigated under laboratory conditions. The existing concept of the EOC was modified to incorporate the system into a state of the art subsurface soil investigation probe (electric cone penetrometer). Partial theoretical support for EOC operation was developed. The state of the art in reactive solute transport in soils was reviewed. From this review inferences were made about time of travel of a permeant in soil samples, which was consequently compared with time of initial response of the laboratory prototype cone penetrometer …

Cadastral Surveying In Colonial South Carolina: A Historical Geography., Linda Marie Pett-Conklin
LSU Historical Dissertations and Theses
Colonial South Carolina's cadastral pattern evolved as the product of a variety of factors. Foremost was the ability of settlers to choose the sites of their landholdings. This authority was limited, however, by official policies that prevented settlers from determining the size, shape, and quality of land in their grants. Expressed rules for surveying riparian and inland tracts in rectangular shapes resulted in a more regular pattern of landownership than is generally assumed in a metes and bounds survey. Within the guidelines of these and other policies, colonist nonetheless were permitted to occupy land in non-contiguous tracts resulting in a …

Sociologists And The Vietnam War: A Historical Document Analysis (Commodification, Post-Industrial)., Robert Earl Sanderson
LSU Historical Dissertations and Theses
Textbooks are important representative statements of certified and legitimated knowledge within an academic discipline, and the manner in which introductory sociology textbooks assess society reflect the power and sophistication of theories in discerning social patterns and structures. That the pivotal historical event of the Vietnam War and its implications for contemporary American social institutions was virtually omitted in our sample of one hundred-twenty textbooks raises critical issues for sociology. Content analysis of Vietnam War era textbooks (1954-1975) revealed 75% of the sample, divided among four major research orienting paradigms extant in sociology, ignored mention of the war and only the …
Spectroscopic Studies Of The Metal Centers In Hydrogenases And Carbon Monoxide Dehydrogenase (Nickel)., Isabel Cristina Zambrano
Spectroscopic Studies Of The Metal Centers In Hydrogenases And Carbon Monoxide Dehydrogenase (Nickel)., Isabel Cristina Zambrano
LSU Historical Dissertations and Theses
The biological activation of hydrogen is catalyzed by hydrogenases. An understanding of the mechanism by which hydrogenases act requires the elucidation of the nature and type of metal centers present in the enzymes. Room temperature UV-visible absorption, low temperature magnetic circular dichroism and electron paramagnetic resonance spectroscopies have been used to characterize the electronic and magnetic properties of the iron-sulfur and nickel centers in hydrogenases from Clostridium pasteurianum, Methanobacterium thermoautotrophicum, and Desulfovibrio gigas. In addition, another Ni-containing enzyme, carbon monoxide dehydrogenase from Clostridium thermoaceticum, and D. gigas Ni-substituted rubredoxin were investigated. The results provide evidence for the presence of conventional …

Model Reduction Of Stochastic And Deterministic Continuous Time Linear Systems (Lypunov Equation, Schawrz Approximation)., Khier Benmahammed
LSU Historical Dissertations and Theses
Two new approaches for reducing the order of large scale continuous systems are presented. The first approach is a modified version of the aggregation technique. It uses the matching properties of the steady state output covariance and the Markov parameters of the high order system to those of the r('th) order model. This approach also uses a new algorithm derived for the computation of the controllability and observability Grammians, to produce controllable, observable and stable low order models. These is no unique method available for evaluating the aggregation matrix or the matrix relating the system state vector to the model …
