"Spades Players" And "Senators": An Ethnography Of Black Subcultures In A Community College., Anthony Louis Molina Sr Jan 1991

"Spades Players" And "Senators": An Ethnography Of Black Subcultures In A Community College., Anthony Louis Molina Sr

LSU Historical Dissertations and Theses

This ethnographic study of Black community college students, in a predominantly white community college, took place over a three-year period and focused on two groups. One group, the spades players, neglected their studies in favor of the card game spades, which they made the central activity of their family-like collective in the student commons. The other group, Black senators in the Student Government Association, were academic achievers who performed service to the college. By immersion into both cultures, the researcher gained the confidence of individual students in both groups, interviewed them in various settings, and looked for reasons behind the …

New Techniques In Scene Understanding And Parallel Image Processing., Krishnakumar Narayanan Jan 1991

New Techniques In Scene Understanding And Parallel Image Processing., Krishnakumar Narayanan

LSU Historical Dissertations and Theses

There has been tremendous research interest in the areas of computer and robotic vision. Scene understanding and parallel image processing are important paradigms in computer vision. New techniques are presented to solve some of the problems in these paradigms. Automatic interpretation of features in a natural scene is the focus of the first part of the dissertation. The proposed interpretation technique consists of a context dependent feature labeling algorithm using non linear probabilistic relaxation, and an expert system. Traditionally, the output of the labeling is analyzed, and then recognized by a high level interpreter. In this new approach, the knowledge …

The Structural Organization Of Photosystem Ii Polypeptides., William Robert Odom Jan 1991

The Structural Organization Of Photosystem Ii Polypeptides., William Robert Odom

LSU Historical Dissertations and Theses

The structural organization of Photosystem II polypeptides has been investigated using the protein crosslinking reagent 1-ethyl-3-(dimethyl-aminopropyl)-carbodiimide (EDC), and a library of mono- and polyclonal antibodies. The first phase of this research was to generate the antibody probes against specific PS II polypeptides. A murine monoclonal antibody, FQC3, was characterized. It recognized the D2 protein of Spinacia oleracea L. The second phase of this research utilized antibodies against D1, D2, CPa-1, CPa-2, Cyt b$\sb{559}$, 33 kDa manganese stabilizing protein (MSP), 24 kDa extrinsic protein, and the 17 kDa extrinsic protein to identify PS II subunits crosslinked by EDC. Several intra-complex crosslinked …

The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne Jan 1991

The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne

LSU Historical Dissertations and Theses

The foliage of thirteen genetic clones of the nitrogen-fixing trees Erythrina berteroana, E. poeppigiana and E. costarricensis growing under similar environmental conditions in the Latin American Nitrogen Fixing Tree Arboretum, CATIE, Turrialba, Costa Rica, was evaluated by gas chromatography/mass spectrometry for toxic alkaloid content. The major alkaloid identified was $\beta$-erythroidine, a naturally derived drug used in the 1950s and 1960s as a neuromuscular blocking agent in surgery and electroshock treatments. Other alkaloids identified were $\alpha$-erythroidine, erybidine, erythraline, erysodine, oxo-$\beta$-erythroidine and several previously undescribed compounds. There was a difference of more than two orders of magnitude in the $\beta$-erythroidine concentration between …

Parallel And Distributed Algorithms For A Class Of Graph-Related Computational Problems., Rajanarayanan Subbiah Jan 1991

Parallel And Distributed Algorithms For A Class Of Graph-Related Computational Problems., Rajanarayanan Subbiah

LSU Historical Dissertations and Theses

There exist at least two models of parallel computing, namely, shared-memory and message-passing. This research addresses problems in both these types of systems, and proposes efficient parallel (Shared-Memory Model) and distributed (message-passing) algorithms for a variety of graph related computational problems. In part I, we design algorithms for three generic problems in distributed systems: set manipulation, network structure recognition and facility placement. We present optimal distributed algorithms for recognizing rectangular-mesh networks. The time and message complexity of our algorithm is linear in the number of nodes in the network. We also lay the foundation for the recognition of 2-reducible, outer-planar …

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver Jan 1991

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver

LSU Historical Dissertations and Theses

Lumber boomed in the Reconstructed South, an industrial binge that, by 1920, changed the landscape, first removing the forest then replacing its subsistence economy with consumerism. Men with money made fortunes in lumber. West of the Mississippi and south of the Missouri, it became a bonanza by 1880. Within these boundaries, black and white farmers and field hands sought "public work" in sawmills and log fronts. Most were unskilled. Steam power changed their lives, although all did not respond alike. They kept their folk ways, consistent with the new industry, despite their bondage to machines. Although most workers voluntarily entered …

A Brooding Eloquence: Amplification And Irony In Marlowe's Dramas., Jeffery Galle Jan 1991

A Brooding Eloquence: Amplification And Irony In Marlowe's Dramas., Jeffery Galle

LSU Historical Dissertations and Theses

My subject is the relationship between rhetoric and the range of possible reaction to Marlowe's protagonists in his five major plays--Tamburlaine I and II, Doctor Faustus, The Jew of Malta, and Edward II. In a very broad sense, I conceive of the rhetoric of each play in terms of opposing rhetorical forces, amplification and irony, and attempt to account for the relative intensity of amplification and irony in each play as I study the rhetoric of the protagonist. One strategy, amplification, entails the investment of a major character with logical arguments from invention, effective arrangement of ideas from disposition, and …

Some Extremal Connectivity Results For Matroids, Safwan Akkari, James Oxley Jan 1991

Some Extremal Connectivity Results For Matroids, Safwan Akkari, James Oxley

Faculty Publications

Let n be an integer exceeding one and M be a matroid having at least n + 2 elements. In this paper, we prove that every n-element subset X of E(M) is in an (n + 1)-element circuit if and only if (i) for every such subset, M X is disconnected, and (ii) for every subset Y with at most n elements, M Y is connected. Various extensions and consequences of this result are also derived including characterizations in terms of connectivity of the 4-point line and of Murty's Sylvester matroids. The former is a result of Seymour. © 1991.

Evaluating Acrosome Interference Contrast Reaction Steps With Brightfield And Differential Microscopy Techniques, H. C. Steinholt, J. E. Chandler, V. Tirado

Faculty Publications

Acrosomal integrity of bovine spermatozoa was evaluated using naphthol yellow S-erythrosine B stain with bright field microscopy, .2% glutaraldehyde fixation with Nomarski optics, and live wet smears with Nomarski optics to compare the evaluation techniques. Four ejaculates per two Holstein bulls were enriched through a Percoll gradient, capacitated with heparin, and acrosome-reacted with lysophosphatidylcholine to prepare spermatozoa for in vitro fertilization. Spermatozoa samples were taken after each preparatory step, and percentage of intact acrosomes was evaluated with the stain, .2% glutaraldehyde, and live wet smear. Acrosomal integrity decreased with each preparatory step across all techniques. The decrease in integrity from …

Individual And Work-Related Variables Contributing To Hospital Nurses' Participation Or Non-Participation In Available Clinical Career Ladder Programs., Sarah Kay Alford Thornhill Jan 1991

Individual And Work-Related Variables Contributing To Hospital Nurses' Participation Or Non-Participation In Available Clinical Career Ladder Programs., Sarah Kay Alford Thornhill

LSU Historical Dissertations and Theses

One solution to overcome the shortage of hospital nurses is to establish and implement clinical career ladder programs. The purpose of this study was to examine hospital clinical nurses' perceptions of ladder programs as a job enrichment strategy and to determine individual and work-related variables contributing most to nurses' participation or nonparticipation in available clinical ladder programs. A random sample of 600 clinical nurses employed full time in five regional medical center hospitals located in Louisiana and Mississippi were the study subjects. Respondents were 106 (88.3%) of the 120 ladder program participants and 385 (80.2%) of the 480 nonparticipant nurses. …

Comparative Overwintering Capabilities Of Africanized And European Honey Bees., Jose Damaso Villa Jan 1991

Comparative Overwintering Capabilities Of Africanized And European Honey Bees., Jose Damaso Villa

LSU Historical Dissertations and Theses

The potential of tropical Africanized honey bees to survive through winter was investigated to predict their possible geographical range and density in the United States. Experiments were conducted in cold rooms, at high elevations in tropical mountains, and during a winter season in Germany. The performance and survival of isolated groups of workers and of intact Africanized colonies were compared with those of European origin, and in some experiments, with those of hybrid crosses. In cold rooms, groups of 40 g of Africanized workers exposed to air currents at 15$\sp\circ$C aggregated in different positions and in tighter conformations than European …

Preservice Teachers' Evolving Perspectives Of Elementary Social Studies., Elizabeth K. Wilson Jan 1991

Preservice Teachers' Evolving Perspectives Of Elementary Social Studies., Elizabeth K. Wilson

LSU Historical Dissertations and Theses

Recent studies which have focused on preservice teachers' perspectives of elementary social studies have attempted to discover the product of the relationships between their conceptions of social studies and their classroom practices. This research, conducted only during the clinical experience, indicated that the beliefs and ideas which teachers express about social studies have little effect on classroom practice. In order to better understand this phenomenon, this study investigated the evolution of preservice teachers' perspectives of social studies through methods instruction as well as the clinical experience. The participants for this study were four preservice teachers who were enrolled in the …

Remedial English Ten Years After: Former Basic Writers In The Workplace., Eleanor Agnew Jan 1991

Remedial English Ten Years After: Former Basic Writers In The Workplace., Eleanor Agnew

LSU Historical Dissertations and Theses

The purpose of this study was to find out whether writing skills were a handicap to job success for former basic writers who had graduated from college. A population of 197 former basic writers (FBW's) and 68 former strong writers (FSW's, used as a comparison) were surveyed and interviewed. Research questions included (1) What types of jobs do FBW's have, compared to FSW's, and how much do their feelings about writing affect their choices of major or job? (2) How much and how often do FBW's write at work compared to FSW's? (3) What forms of writing do FBW's do …

Cooperation In The Liberalization Of Soviet-Western Trade? A Transaction-Cost Analysis Of Soviet Joint Ventures With The West., Elza Perry Ballard Jan 1991

Cooperation In The Liberalization Of Soviet-Western Trade? A Transaction-Cost Analysis Of Soviet Joint Ventures With The West., Elza Perry Ballard

LSU Historical Dissertations and Theses

This study employs the method of transaction-cost analysis--the price of doing business between economic and political agents--to the study of Soviet-Western political economy (particularly Soviet joint ventures with the West). Its purpose is to determine: (1) if Soviet foreign economic policy in the Gorbachev era has reduced the transaction costs to Western firms engaging in joint ventures with the Soviet Union when compared to previous Western business options (e.g., co-production, licensing, turn-key projects), and (2) if the reduction is sufficient to encourage joint ventures to become a mechanism of greater cooperation and liberalization in Soviet-Western political economy and the international …

An Ethnographic Investigation Of The Integration Of Disabled And Nondisabled Two-Year-Old Children., Mary Beth Armstrong Jan 1991

An Ethnographic Investigation Of The Integration Of Disabled And Nondisabled Two-Year-Old Children., Mary Beth Armstrong

LSU Historical Dissertations and Theses

This study is an ethnographic investigation of the initial integration of a group of disabled and nondisabled two-year-old children. The group was comprised of a class of seven disabled children from a school parish and a class of nine nondisabled children from a university child development center in this same parish. This study incorporated ethnographic data collection and analysis procedures. Data collection procedures included participant observation, ethnographic interviews, artifactual analysis, and videorecording. The results of this study suggest that a process of stigmatization occurred in this integration program. The process of stigmatization and factors perhaps accounting for the process are …

A Blackboard Architecture For The Integration Of Manufacturing Systems., Calvin Michael Collins Jan 1991

A Blackboard Architecture For The Integration Of Manufacturing Systems., Calvin Michael Collins

LSU Historical Dissertations and Theses

American companies engaged in manufacturing are in the midst of adjusting to the increasingly stiff foreign competition as they attempt to satisfy the demands of expanding markets. U.S. manufacturing must continue the movement toward leaner, more streamlined production if they are to survive with the new market realities. Computerizing different aspects in the accounting, production, planning, and marketing divisions, has been central in the quest for higher productivity for four decades. Research is now centering on the integration of these systems and the goal is to integrate the accounting, planning and marketing functions of the organization with the automated manufacturing …

A Syntactic Language Computer Analysis Of Depressed Versus Non-Depressed Females., Daniel Merton Christy Jan 1991

A Syntactic Language Computer Analysis Of Depressed Versus Non-Depressed Females., Daniel Merton Christy

LSU Historical Dissertations and Theses

This study sought to examine the interrelationship of cognition and language in the clinical syndrome of depression. It was proposed that the types of cognitive differences in depression proposed by Beck and other cognitive theorists would be reflected in language usage, and especially in syntax. Using the Beck Depression Inventory (BDI), subjects were classified as either depressed (BDI $\geq$ 16) or non-depressed (BDI $\leq$ 4). Subjects were asked to speak into a tape recorder for 3-5 minutes on each of three stimuli, a positive event, a negative event, and a neutral opinion stimulus. The language samples were then analyzed using …

A Neural Network Truth Maintenance System., Suresh Guddanti Jan 1991

A Neural Network Truth Maintenance System., Suresh Guddanti

LSU Historical Dissertations and Theses

A novel approach using Neural Networks has been developed to generate consistent labelling of facts in relation to a given set of rules. In the proposed system, facts are represented by neurons and their interconnections form the knowledge base. The Neural Network Truth Maintenance System(TMS) arrives at a valid solution provided the solution exists. A valid solution is a consistent labelling of facts. If a valid solution does not exist the network does not converge. An experimental setup was built and tested using conventional integrated circuits. The hardware design is suitable for VLSI implementation for large, real-time problems. The TMS …

The Introduction Into Tobacco Plants Of Genes Which Encode Some Of The Natural Components Of The Humoral Immune Response Of Hyalophora Cecropia., Luis Julio Cesar Destefano Beltran Jan 1991

The Introduction Into Tobacco Plants Of Genes Which Encode Some Of The Natural Components Of The Humoral Immune Response Of Hyalophora Cecropia., Luis Julio Cesar Destefano Beltran

LSU Historical Dissertations and Theses

A number of plant pathogenic bacteria has been shown to be highly sensitive to SB-37, a derivative of cecropin B (one of the three cecropins from the giant silk moth Hyalophora cecropia). The lytic activity exhibited by SB-37 has been shown to increase up to twenty-fold in the presence of chicken egg white lysozyme. The cDNAs genes encoding SB-37, attacin E (another component of the humoral response of Hyalophora cecropia), and chicken lysozyme have been introduced into tobacco (var Xanthi) and potato (a new cultivar 86007) plants by Agrobacterium-mediated transformation using co-integrate and binary vectors. The genes were placed under …

School Administration As Brinkmanship., Eddy A. Haynes Jan 1991

School Administration As Brinkmanship., Eddy A. Haynes

LSU Historical Dissertations and Theses

Students, teachers, and principals sometimes test the boundaries set by the system in which they work, often with the goal of adapting to their circumstances while avoiding punishment. This type of behavior, called brinkmanship, was defined by Licata and Willower (1975) in terms of subordinate challenges to an educational organization's authority system that avoid negative sanctions. Principal brinkmanship can also be defined in terms of discretionary decision making (Morris, et al. 1984) which is the implementation of policies and programs at the school level in a way that fits the principal's values, philosophy, and goals. This research focused on school …

Faulkner, Truth, And The Artist's Directive: A Reading Of "A Fable"., Bobby Lynn Matthews Jan 1991

Faulkner, Truth, And The Artist's Directive: A Reading Of "A Fable"., Bobby Lynn Matthews

LSU Historical Dissertations and Theses

The old general in A Fable embodies the resolution of questions about the relation of art and life that Faulkner evoked in his invention of Quentin Compson in The Sound and the Fury and pursued in a series of subsequent characterizations. This artist-figure motif discloses Faulkner's implication of the relation in the modern crisis of faith. Faulkner images in narrative fiction what Nietzsche asserts in discourse, namely, the need for a reversal of the Platonic valuation of eternal "truth" (ideality) over art. The characterization of Quentin shows the potentially terrible consequences of man's propensity for mythopoeic invention, as Quentin's unconscious …

Structural And Functional Studies Of Carbohydrates., Shirish Trymbak Dhume Jan 1991

Structural And Functional Studies Of Carbohydrates., Shirish Trymbak Dhume

LSU Historical Dissertations and Theses

Plasmodium falciparum is the parasite responsible for a major loss of human life due to malaria. The biochemistry of invasion of the parasite into human red cells is the subject of much study and controversy. The receptor mediated endocytosis of the parasite into the red cells is postulated to involve at least two major receptors on the cells. Earlier work focussed on glycophorin of red cells as a likely receptor. The present study focussed on the role of erythroglycan, the N-linked carbohydrate chain of band 3 of human red cells in the invasion process. Erythroglycan showed high levels of inhibition …

Family Support For Persisters And Non-Persisters In Louisiana's Adult Basic Education Programs., Geraldine Hargrove Holmes Jan 1991

Family Support For Persisters And Non-Persisters In Louisiana's Adult Basic Education Programs., Geraldine Hargrove Holmes

LSU Historical Dissertations and Theses

The role that family involvement and the effects of home efforts have on improved student achievement for children is well documented in the literature. The purpose of this study was to determine whether family support should be considered when planning adult basic education (ABE) programs. The objectives addressed were: demographic characteristics, level of family support, and relationship of family support among selected variables. A statewide random sample of 197 adult basic education students was surveyed (82.7% response rate). Persisters (students who either completed the ABE program or were continuing their instruction when the study was conducted) and non-persisters (students who …

An Analysis Of Syntactic Skills Used In Translating Natural Language Sentences Into Algebraic Equations., Elizabeth Devalcourt Gray Jan 1991

An Analysis Of Syntactic Skills Used In Translating Natural Language Sentences Into Algebraic Equations., Elizabeth Devalcourt Gray

LSU Historical Dissertations and Theses

The purpose of this study is to determine how a competent person translates a natural language sentence into an algebraic equation. A current theory of how translation occurs is espoused by a group of cognitive scientists who propose that the competent translator uses only conceptual strategies in the translation process. I propose and investigate an alternate theory that the translation skills of a competent student are based on a syntactic analysis and syntactic manipulation of the sentence. In most cases such direct, syntactic translation processes will suffice, but for a small minority of sentence types a decision must be made …

Organic Matter Variation Within Depositional Sequences: Stratigraphic Significance And Implication To Petroleum Source Rock Prediction., Mark Alan Pasley Jan 1991

Organic Matter Variation Within Depositional Sequences: Stratigraphic Significance And Implication To Petroleum Source Rock Prediction., Mark Alan Pasley

LSU Historical Dissertations and Theses

Study of Eocene-Oligocene sediments in Alabama and Upper Cretaceous strata in New Mexico shows that organic facies deposited on the shelf change noticeably at surfaces associated with transgression of the shoreline. Organic matter in sediments below transgressive surfaces is dominated by well preserved terrestrial organic matter (phytoclasts) whereas sediments deposited on the shelf during transgression contain sparse, highly degraded phytoclasts. Shelf deposits associated with transgressions generally contain more hydrogen-rich organic matter than those deposited during regression. Sediments associated with starvation surfaces contain abundant amorphous nonstructured protistoclasts and rare, highly degraded phytoclasts. Well preserved phytoclasts increase in abundance in sediments overlying …

In Vitro Culture Of Bovine Uterine And Oviduct Epithelial Cells., John Kevin Thibodeaux Jan 1991

In Vitro Culture Of Bovine Uterine And Oviduct Epithelial Cells., John Kevin Thibodeaux

LSU Historical Dissertations and Theses

A reliable procedure was developed to harvest purified populations of bovine uterine epithelial cells from the luminal endometrium that allowed cells to be maintained in vitro for multiple subpassages. This method allowed adequate numbers of cells for in vitro culture studies to evaluate uterine secretion rates, uterine-embryo interactions and a new embryo co-culture system. In a second study, cells were isolated from the uterus and oviducts collected from cattle on day of estrus, on d 4 to 6, d 8 to 10 and d 14 to 16 of the cycle to monitor growth and development following incubation in vitro. The …

A Reading Of "A Good Man Is Hard To Find" And "A Curtain Of Green": The Influence Of Parable On Flannery O'Connor And Eudora Welty., Allison Carol Chestnut Jan 1991

A Reading Of "A Good Man Is Hard To Find" And "A Curtain Of Green": The Influence Of Parable On Flannery O'Connor And Eudora Welty., Allison Carol Chestnut

LSU Historical Dissertations and Theses

A Good Man is Hard to Find by Flannery O'Connor and A Curtain of Green by Eudora Welty are short story cycles harmonized by their marked imitation of the style and structure of parable. O'Connor added stories after initially sending the collection to the publisher and then rearranged them accordingly; her work represents a completed cycle. Welty's collection, published in an order different from their individual publications and their original placement in an early typescript, is an arranged cycle. Moreover, parabolic style and structure unify each cycle. A parable typically is a brief story told in the past tense, usually …

Effects Of Chronic Administration Of Phenylbutazone On Reproduction In The Mare., Mareth Ellsworth Jan 1991

Effects Of Chronic Administration Of Phenylbutazone On Reproduction In The Mare., Mareth Ellsworth

LSU Historical Dissertations and Theses

Phenylbutazone is a non-steroidal anti-inflammatory drug that acts by inhibiting prostaglandin synthesis. Prostaglandins are associated with crucial aspects of reproduction. In 5 experiments, mares were used to test the effects of phenylbutazone on reproduction. In all experiments, treatment was 2 g phenylbutazone or 10 ml physiological saline intravenously(control). In Experiment I, 9 mares were phenylbutazone-treated for 180 consecutive days and teased. Ovaries were palpated and cyclicity was verified by circulating progesterone concentrations. Thirty-six cycles were evaluated. Mares were then divided into treatment and control groups. Estrous mares were artificially inseminated. Non-surgical embryo collection was performed 7 to 8 days post-ovulation. …
