Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman Jan 1993

Disclosure Decisions And Patterns After A Near-Death Experience., Regina M. Hoffman

LSU Historical Dissertations and Theses

As a dimension of privacy regulation, self-disclosure is the means through which individuals manage the psychological boundary area between the inner, private world and the outer, public world of interaction with others. In communication research, a gap has been noted between self-disclosure as defined by scientific method and self-disclosure as it is experienced by people in their daily life. This study reduces that gap by investigating disclosure decisions about a major life experience through the thick perspectives of the individuals themselves. Disclosure is examined as a context-embedded communicative process. To provide a thick description of disclosure decisions, an ethnographic methodology …

Optical Character Recognition Using Morphological Attributes., Gili Mendel Jan 1993

Optical Character Recognition Using Morphological Attributes., Gili Mendel

LSU Historical Dissertations and Theses

This dissertation addresses a fundamental computational strategy in image processing hand written English characters using traditional parallel computers. Image acquisition and processing is becoming a thriving industry because of the frequent availability of fax machines, video digitizers, flat-bed scanners, hand scanners, color scanners, and other image input devices that are now accessible to everyone. Optical Character Recognition (OCR) research increased as the technology for a robust OCR system became realistic. There is no commercial effective recognition system that is able to translate raw digital images of hand written text into pure ASCII. The reason is that a digital image comprises …

Discourses Of Maternity And The Postmodern Narrative: A Study Of Lessing, Walker, And Atwood., Janet J. Montelaro Jan 1993

Discourses Of Maternity And The Postmodern Narrative: A Study Of Lessing, Walker, And Atwood., Janet J. Montelaro

LSU Historical Dissertations and Theses

Doris Lessing's The Golden Notebook, Alice Walker's The Color Purple, and Margaret Atwood's The Handmaid's Tale are narrated by women whose social identities are partially constructed through activities traditionally associated with mothering. In each text, maternity signifies a biological event as well as the social, sexual, and material relations involved with pregnancy, childbirth, and the nurturing and rearing of children, activities which become grounds for investigating the politics of the body, of sexuality, and consequently, of gender relations. Maternity becomes politicized within the cultural contexts of each novel as maternal experience functions to produce both feminist and postmodernist critiques. In …

Attitude Formation And Development: An Investigation Of The Interrelationships Among Attitudinal Constructs And Their Resistance To Counterpersuasion., Melodie Ree Phillips Jan 1993

Attitude Formation And Development: An Investigation Of The Interrelationships Among Attitudinal Constructs And Their Resistance To Counterpersuasion., Melodie Ree Phillips

LSU Historical Dissertations and Theses

The study examined the resistance of attitudes to counterpersuasion using the Elaboration Likelihood Model as a framework for analysis. The ELM postulated the centrally formed attitudes are more resistant to counterpersuasion than peripherally formed attitudes. A negative publicity setting was used to introduce respondents to a longitudinal study of attitude formation and change. A model was developed hypothesizing the role of company and brand cognitions would be significant in the formation of attitudes and intentions in central processors. It was hypothesized that A$\sb{\rm Ad}$ would be the primary influence on company and brand attitudes for peripheral processors. A sample of …

Studies On The Energy Mobilizing Hormones In Insects., Subrata Das Jan 1993

Studies On The Energy Mobilizing Hormones In Insects., Subrata Das

LSU Historical Dissertations and Theses

Chemical factors controlling the energy mobilization in three species of insects were identified, partially characterized and their role in the process of energy mobilization were studied. High performance liquid chromatographic fractions were isolated from methanolic extracts of the corpora cardiaca (CC) from the honeybee Apis mellifera, the paper wasp Polistes exclamans and the house cricket Acheta domesticus. Each species had a single active fraction that was able to elevate the lipid titer in Acheta. Pyroglutamate aminopeptidase digestion of isolated active fractions indicated that these molecules are all peptides with a terminal pyroglutamate. Methanolic extracts of CC from Apis, Polistes and …

Acetylation Of Seaweed Alginate By Pseudomonas Syringae., Jin Woo Lee Jan 1993

Acetylation Of Seaweed Alginate By Pseudomonas Syringae., Jin Woo Lee

LSU Historical Dissertations and Theses

Acetylation of bacterial alginate by Pseudomonas syringae subsp. phaseolicola ATCC 19304 was independent of alginate biosynthesis. This allowed the development of a process for acetylating seaweed alginate using immobilized P. syringae ATCC 19304 cells. About 50% of the mannuronic acid residues of seaweed alginate were acetylated by carbon immobilized P. syringae cells in a fluidized bed, up-flow reactor system fed continuously with seaweed alginate and gluconic acid. O-Acetylation by this process was found to be specific for the C-2 and/or C-3 position(s) of mannuronate residues. Acetylated seaweed alginate showed altered properties including increased viscosity and changed affinities for some cations.

"Sequenza Vii" By Luciano Berio: Background, Analysis And Performance Suggestions., Carrie Marie Vecchione

LSU Historical Dissertations and Theses

Sequenza VII by Luciano Berio is regarded as one of the major twentieth-century pieces for the oboe. Its unique sounds and logic make it both fascinating and complex. Great demands are put on the performer, who must produce difficult, unconventional sounds. The listener is likewise challenged to accept this new language. An initial hearing can leave a listener excited though baffled, as a first look at the score can cause trepidation even in a fearless performer. The purpose of this paper is to find some order to this compelling piece. This comprehensive study is undertaken from three different perspectives, each …

Characterization Of Physiological Responses Of Suspension Cells From Alligator Weed (Alternanthera Philoxeroides (Mart.); Griseb) To An Abrupt Increase In Salinity., Gloria Balagtas-Burow Jan 1993

Characterization Of Physiological Responses Of Suspension Cells From Alligator Weed (Alternanthera Philoxeroides (Mart.); Griseb) To An Abrupt Increase In Salinity., Gloria Balagtas-Burow

LSU Historical Dissertations and Theses

Dark-grown suspension cells of alligator weed (Alternanthera philoxeroides (Mart.) Griseb) were established in Murashige and Skoog medium and used to characterize several cellular responses to an abrupt increase in salinity (0 to 200 mol m$\sp{-3}$ NaCl). The fresh weight and cell density of salt-treated cells of alligator weed more than doubled by 7 d. Cell viability declined to 77% by 1 d, but recovered to 86% by 7 d after salt treatment. These responses indicate that alligator weed cells survived and adapted to an abrupt increase in salinity. Osmotic potential ($\psi\sb\pi$) of salt-treated cells declined to the $\psi\sb\pi$ of the …

A Study Of Heat Transfer In Rotary Desorbers Used To Remediate Contaminated Soils., Charles Alan Cook Jan 1993

A Study Of Heat Transfer In Rotary Desorbers Used To Remediate Contaminated Soils., Charles Alan Cook

LSU Historical Dissertations and Theses

A comprehensive heat transfer model is developed which describes heat transfer phenomena in rotary desorbers. This model predicts the temperatures of the solids bed and gases in the desorber and the rate of water evaporation from the solids. Emphasis is placed on describing the heat transfer process between the rotating wall of a desorber and the adjacent bed of solids. A heat-balance integral method is used to model heat conduction from the wall to adjacent wet bed particles. This solution includes the effects of water evaporation near the wall and a thermal contact resistance between the wall and the first …

In Situ Determination Of Capillary Pressure And Relative Permeability Curves Using Well Logs., Adel Afifi Ibrahim Jan 1993

In Situ Determination Of Capillary Pressure And Relative Permeability Curves Using Well Logs., Adel Afifi Ibrahim

LSU Historical Dissertations and Theses

A pressure profile obtained from the formation tester defines the wettability, free water level, and hydrocarbon and water densities as well as the capillary pressure above the free water level. Correlating the pressure values to the water saturation values determined from the resistivity logs results in a capillary pressure/water saturation, $\rm P\sb{c}(S\sb{w}),$ curve characteristic of the reservoir. A relative permeability curve then can then be derived from this $\rm P\sb{c}(S\sb{w})$ curve using empirical relationships. This approach was tested in the laboratory using an eight-foot vertical sandstone core to simulate the formation. The core was fitted with electrode arrays, and resistivity …

The Interrelationships Of Rotylenchulus Reniformis Linford And Oliveira With Rhizoctonia Solani Kuhn On Cotton., Ambalavanan Sankaralingam Jan 1993

The Interrelationships Of Rotylenchulus Reniformis Linford And Oliveira With Rhizoctonia Solani Kuhn On Cotton., Ambalavanan Sankaralingam

LSU Historical Dissertations and Theses

The interrelationships between the reniform nematode, Rotylenchulus reniformis Linford and Oliveira, and the fungus Rhizoctonia solani Kuhn were studied on cotton (Gossypium hirsutum L.). Parasitism of cotton seedlings by R. solani resulted in enhanced reproduction of R. reniformis. In the presence of the fungus, there was increased egg production by the nematode which resulted in augmented soil population density. Enhanced reproduction of the nematode in the presence of the fungus was consistent across isolates of R. solani, populations and inoculum levels of R. reniformis, and cotton cultivars. The nematode did not influence the severity of seedling blight disease. At 90 …

Rewriting The Masculine: The National Subject In Modern American Drama., Francis Granger Babcock Jan 1993

Rewriting The Masculine: The National Subject In Modern American Drama., Francis Granger Babcock

LSU Historical Dissertations and Theses

This dissertation traces the development of an American masculinity, using the concept of the national subject (borrowed from Frantz Fanon), through three different stages of the American capitalism: mercantile, or market, monopoly, and corporate, or late-capitalism. It constructs a genealogy of American maleness and then examines how this genealogy was altered and reconstituted during times of economic crisis and technological innovation. It argues that successive technological revolutions in the symbolic apparatus of American culture allowed elite political and economic interests to gain consensus by deploying the national subject using various media. In the early national period Franklin and Crevecoeur used …

Mass Belief Systems Reconsidered: Myths And Political Thought., Bryan Douglas Vincent Jan 1993

Mass Belief Systems Reconsidered: Myths And Political Thought., Bryan Douglas Vincent

LSU Historical Dissertations and Theses

This dissertation is a response to Bennett's (1977) call for a theoretical framework capable of integrating existing theories of mass belief systems. The theory offered here is built on two important discoveries in this body of research: the importance of simplifying heuristics and the hierarchical structure of belief systems. Recognizing that heuristics are described in a narrative form, the general importance of narrative for political cognition is suggested and explored. Of particular importance is the possibility that hierarchical belief systems are grounded in core narratives or myths. After demonstrating the theoretical links between myth and belief system, a way of …

Attentional Bias And Subjective Risk In Hypochondriacal Concern., Polly Beth Hitchcock Jan 1993

Attentional Bias And Subjective Risk In Hypochondriacal Concern., Polly Beth Hitchcock

LSU Historical Dissertations and Theses

Although cognitive theories suggest that attentional bias to illness stimuli and inflation of subjective risk of future negative health events are etiologically related to hypochondriacal concern, little empirical research has been conducted on these cognitive distortions. The present study investigated attentional bias, as inferred from RTs on an attentional search information processing paradigm, and subjective risk, as measured by probability judgments of future health events, in 200 medical outpatients differing in level of hypochondriacal concern. It was hypothesized that hypochondriacal concern would be associated with specific cognitive biases for illness-related, as opposed to socially threatening, stimuli. It was also hypothesized …

Mathematical Model Of Hairy Root Growth., Seungdo Kim Jan 1993

Mathematical Model Of Hairy Root Growth., Seungdo Kim

LSU Historical Dissertations and Theses

Hairy roots produce secondary metabolites which have been used as specialty chemicals. The mathematical models of hairy root growth kinetics can guide the design and scale-up of root cultures. An unstructured segregated and a chemically structured segregated models for hairy growth kinetics are formulated with rules of root branching processes. The deterministic branching rule and the stochastic branching rule are studied. For the deterministic rule where two branching parameters are assumed constant, the number of tips can be obtained by solving a linear difference equation. The conceptual framework established for the deterministic rule is used to formulate a stochastic rule …

Mobilization Of A Hydrophobic Organic Compound Using Surfactant For Soil Washing., Minwen Liu Jan 1993

Mobilization Of A Hydrophobic Organic Compound Using Surfactant For Soil Washing., Minwen Liu

LSU Historical Dissertations and Theses

Soil washing using surfactants is a promising alternative for the conventional pump-and-treat method of removing hydrophobic organic compounds. The interactions and the transport of the chemicals have been studied by batch and column experiments. Sodium dodecylsulfate (SDS), an anionic surfactant, and anthracene, a hydrophobic organic, were chosen as the representative surfactant and contaminant, respectively. Fine sand and native soil were used as formation media. The experimental results indicated that the maximum loss of SDS on native soil from the solution was observed when the aqueous SDS concentration was in the region of the critical micelle concentration, and this loss was …

The Role Of Flagellar Proteins In Adhesion Of Vibrio Parahaemolyticus, And Isolation Of The Corresponding Gene(S)., Ratchanee Hongprayoon

LSU Historical Dissertations and Theses

Polar flagellar core protein was purified from Vibrio parahaemolyticus by differential centrifugation and cesium chloride isopycnic centrifugation. Twelve hybridomas secreting monoclonal antibodies against flagellar core protein (MAb-flc) were obtained from fusions. By chance, one purified flagellar core preparation retained flagellar sheath and as a consequence, two hybridomas were detected which secreted anti-sheath antibodies (MAb-fls). MAb-flc and MAb-fls reacted specifically with their corresponding antigens as demonstrated by immunogold labelling. Coagglutination reagents prepared with MAb-flc and MAb-fls were tested against 34 strains of V. parahaemolyticus and 34 heterologous Vibrio species. The coagglutination results revealed that the flagellar core was species-specific while the …

Mathematics And Gender: A General History Of Recent Research And Common Perceptions., Mary E. Reeves Jan 1993

Mathematics And Gender: A General History Of Recent Research And Common Perceptions., Mary E. Reeves

LSU Historical Dissertations and Theses

In the last two decades a tremendous volume of research data has been collected about differences between female and male students in mathematics. But although the amount of data collected has been large, there have been few conscious attempts to understand this data in social, economic, technological, and political terms. This history of academic research on gender differences connects the explosion of academic interest in the 1970s and 1980s with the launch of Sputnik in 1957 and the sense of technological crisis that pervades mathematics education and popular consciousness. The emergence of "Women's Lib" and interest in gender equity in …
