Intensional Query Processing In Deductive Database Systems., Il Yeol Song Jan 1988

Intensional Query Processing In Deductive Database Systems., Il Yeol Song

LSU Historical Dissertations and Theses

This dissertation addresses the problem of deriving a set of non-ground first-order logic formulas (intensional answers), as an answer set to a given query, rather than a set of facts (extensional answers), in deductive database (DDB) systems based on non-recursive Horn clauses. A strategy in previous work in this area is to use resolution to derive intensional answers. It leaves however, several important problems. Some of them are: no specific resolution strategy is given; no specific methodologies to formalize the meaningful intensional answers are given; no solution is given to handle large facts in extensional databases (EDB); and no strategy …


Neural Networks With Asynchronous Control., Michael Christopher Stinson Jan 1988

Neural Networks With Asynchronous Control., Michael Christopher Stinson

LSU Historical Dissertations and Theses

Neural network studies have previously focused on monolithic structures. The brain has a bicameral nature, however, and so it is natural to expect that bicameral structures will perform better. This dissertation offers an approach to the development of such bicameral structures. The companion neural structure takes advantage of the global and subset characteristics of the stored memories. Specifically we propose the use of an asynchronous controller C that implies the following update of a probe vector x by the connection matrix T: $x\sp\prime$ = sgn (C(x, TX)). For a VLSI-implemented neural network the controller block can be easily placed in …


Applications Of Solid State Deuterium Nmr Spectroscopy To Organotransition Metal Complexes., Maria Ines Altbach Jan 1988

Applications Of Solid State Deuterium Nmr Spectroscopy To Organotransition Metal Complexes., Maria Ines Altbach

LSU Historical Dissertations and Theses

Solid-state deuterium NMR spectroscopy has been applied to several organometallic complexes. The deuterium quadrupole coupling constants for cis-($\mu$-C$\sp{\rm 2}$H$\sb{\rm 2}$)($\mu$-CO) (FeCp$\sp{\rm d=5}$(CO)$\rbrack\sb{\rm 2}$ (Cp$\sp{\rm d=5}$ = 5% deuteriated cyclopentadienyl), trans-($\mu$-C$\sp{\rm 2}$H$\sb{\rm 2}$) (MnCp$\sp{\rm d=2.7}$(CO)$\sb{\rm 2}$) $\sb{\rm 2}$ (Cp$\sp{\rm d=2.7}$ = 2.7% deuteriated cyclopentadienyl), and trans-($\mu$-C$\sp{\rm 2}$H$\sb{\rm 2}$ (CoCp$\sp{\rm d=5}$(CO)) $\sb{\rm 2}$ were determined by conventional solid-state deuterium NMR spectroscopy. The charges on the methylene bridging site for the three bridging methylene metal dimers were calculated by modeling the difference in deuterium quadrupole coupling constant between the sample and the reference molecule, (9,9-$\sp{\rm 2}$H$\sb{\rm 2}$)fluorene, by the change in occupancy of …


The Relationship Between Root Anatomic And Metabolic Responses To Soil Waterlogging In The Coastal Grass Spartina Patens., David Maaloe Burdick Jan 1988

The Relationship Between Root Anatomic And Metabolic Responses To Soil Waterlogging In The Coastal Grass Spartina Patens., David Maaloe Burdick

LSU Historical Dissertations and Theses

Spartina patens is a perennial grass that dominates dune, swale and marsh habitats in coastal Louisiana. Plant roots require oxygen for respiration and normal root function, and one of the most serious problems wetland plants encounter is the development of anaerobic conditions in the soil. The remarkable success of S. patens in habitats that occupy distant positions on a soil waterlogging gradient suggests either genetic differentiation or phenotypic adaptation among these populations. Field and greenhouse investigations were conducted to: (1) identify anatomic and metabolic soil waterlogging responses in Spartina patens, (2) examine the relationship between these responses, and finally (3) …


A Study Of The Interaction Of Peroxidic Tumor Promoters With Mitochondria., Christopher Henry Kennedy Jan 1988

A Study Of The Interaction Of Peroxidic Tumor Promoters With Mitochondria., Christopher Henry Kennedy

LSU Historical Dissertations and Theses

When micromolar concentrations of benzoyl peroxide (BPO) are added to rat liver mitochondria, inhibition of mitochondrial NADH-oxidase and succinoxidase is observed. The addition of a classical uncoupler of oxidative phosphorylation results in only partial release of this inhibition, suggesting that BPO inhibits both electron- and energy-transfer in mitochondria. Difference spectroscopy and artificial electron donor results indicate that BPO interacts at coupling site II between cytochromes b and c$\sb1$. BPO only yields radicals in mitochondria via inhibition of electron transport, which results in the formation of superoxide radicals. BPO also induces rapid, large-amplitude swelling of mitochondria; the swelling is dependent on …


Studies On The Reactions Of Polycyclic Aromatic Hydrocarbons With Nitrogen-Dioxide In Aprotic Solvents., Giuseppe Luciano Squadrito Jan 1988

Studies On The Reactions Of Polycyclic Aromatic Hydrocarbons With Nitrogen-Dioxide In Aprotic Solvents., Giuseppe Luciano Squadrito

LSU Historical Dissertations and Theses

There is recent evidence that free radical nitration reactions occur in polluted urban air, and that the nitrated polycyclic aromatic hydrocarbons (NO$\sb2$-PAH) produced by this reaction pathway account for a substantial amount of the total NO$\sb2$-PAH found in ambient particulate organic matter. The nitration of PAH with nitrogen dioxide in solvents of low polarity has been studied as a model for the reactions occurring in the atmosphere (gas phase). While vast amounts of data are available for the electrophilic ionic nitration and its mechanism of reaction is considered well-established (and often included in sophomore Chemistry books), the literature documents relatively …


An Investigation Of The Fungus, Balansia Cyperi Edg., And Its Effect On Purple Nutsedge, Cyperus Rotundus L., Mary Elizabeth Stovall Jan 1988

An Investigation Of The Fungus, Balansia Cyperi Edg., And Its Effect On Purple Nutsedge, Cyperus Rotundus L., Mary Elizabeth Stovall

LSU Historical Dissertations and Theses

This study was designed to investigate host specificity of the fungus Balansia cyperi Edg. on Cyperus rotundus L. (purple nutsedge) and to determine the effect of fungus presence on the biology and ecology of the sedge. Isolates of epiphytic Balansias from C. rotundus and C. virens had similar cultural characters, conidium morphology, and extracellular enzyme activity in artificial culture. However, B. cyperi from C. rotundus had a faster growth rate, greater conidium production, and higher temperature optimum than did the isolate from C. virens. Artificial infection of C. rotundus by B. cyperi from C. rotundus was far more successful than …


Amino Acid Responses Of Olfactory Bulb Cells In The Channel Catfish., Hilary Winfield Thompson Jan 1988

Amino Acid Responses Of Olfactory Bulb Cells In The Channel Catfish., Hilary Winfield Thompson

LSU Historical Dissertations and Theses

Amino acid (AA) responses of olfactory bulb (OB) mitral cells (MC) in the catfish, Ictalurus punctatus, were studied electrophysiologically. A total of 63 cells were recorded in 28 fish in two separate experiments. For the first study, 27 cells in 22 fish were studied with olfactory tract (OT) intact during stimulation with 10$\sp{-6}$ M to 10$\sp{-2}$ M concentrations of 11 AA. MC responses were quantified by interspike interval (ISI) variables sensitive to inhibition (maximum ISI) and excitation (number of action potentials (AP), minimum ISI). APs were also counted in subdivisions to produce a measure sensitive to MC response temporal patterning. …


Aspects Of Vowel Perception By Normal Hearing And Hearing Impaired Listeners., Joan Marie Besing Jan 1988

Aspects Of Vowel Perception By Normal Hearing And Hearing Impaired Listeners., Joan Marie Besing

LSU Historical Dissertations and Theses

The effect of durational differences on the identification of vowel tokens was studied using ten normal hearing and six hearing impaired subjects. Stimuli were synthetically generated and varied in duration of the steady state, durations of the initial and final transitions and F1/F2/F3 location. Listeners were required to identify the given vowel token from a set of ten possible alternatives. The results from the normal hearing group supported the established effects of duration on the perception of vowels. However, these effects were different depending on the frequency locations of F1/F2/F3. Further, changes in the duration of the initial transition had …


A Comparison Of The Effectiveness Of The Operating Funds Flow Measures Of Cash, Net Quick Assets, And Working Capital In Predicting Future Cash Flow., Catherine Innes Green Gaharan Jan 1988

A Comparison Of The Effectiveness Of The Operating Funds Flow Measures Of Cash, Net Quick Assets, And Working Capital In Predicting Future Cash Flow., Catherine Innes Green Gaharan

LSU Historical Dissertations and Theses

In Statement of Financial Accounting Standards No. 95, "Statement of Cash Flows," the Financial Accounting Standards Board requires a statement of cash flows in place of a statement of changes in financial position. This information is assumed to be useful in predicting future cash flow. The first part of this three-part study empirically tests this assumption by comparing the abilities of three operating funds flow measures (working capital, net quick assets, and cash) to predict future cash flows. The second part of this study determines whether the reporting concept best for predicting future cash flow is dependent upon industry classification. …


Dehalogenation In Marine Sediments Containing Natural Sources Of Halophenols., G. M. King Jan 1988

Dehalogenation In Marine Sediments Containing Natural Sources Of Halophenols., G. M. King

Faculty Publications

Halophenols such as 2,4-dibromophenol (DBP) occur naturally in some marine sediments, as a consequence of various animal and algal activities. In an earlier study, DBP was observed in the burrow microenvironment of the hemichordate Saccoglossus kowalewskii. At the concentrations found in the burrow lining, aerobic respiration appeared to be inhibited significantly relative to anaerobic catabolism. This effect, as well as factors contributing to the degradation of DBP, has been documented further here. Results from the addition of radiolabeled DBP to oxic and anoxic sediment slurries and growth experiments with aerobic and anaerobic enrichments suggested that aerobes did not significantly metabolize …

The Relationship Between Learned Sexual Values And Adjustment In A Prison Setting., James William Robinson Jan 1988

The Relationship Between Learned Sexual Values And Adjustment In A Prison Setting., James William Robinson

LSU Historical Dissertations and Theses

The degree of environmental control exerted by female inmates was examined as a function of gender role identity. The sample was obtained at the Louisiana Correctional Institute for Women, the only female prison in the state. The prison environment was assumed to offer very few control options. The options studied were those under the direct authorization of the social services division of the prison, and from individuals external to the prison. It was assumed that the flexibility found in androgynous individuals would allow for a greater level of perceived control than with either the masculine or feminine gender role identity …


Global Zones Of Particle Precipitation., Muhammad Adel Miah Jan 1988

Global Zones Of Particle Precipitation., Muhammad Adel Miah

LSU Historical Dissertations and Theses

Magnetospheric particles are precipitated at low altitude all over the globe. The study of the physics of the equatorial global zone is important for geospace environment modeling, for knowing the loss processes of radiation belt particles and for the Space Station Project. The equatorial global zone was investigated by the Phoenix-1 experiment on board the S81-1 mission in May through November, 1982. The global profile of the peak flux of quasi-trapped protons follows the line of minimum magnetic field strength, with a FWHM of $\sim$13$\sp\circ$ in latitude. The pitch angle distribution anisotropy index is found to be 19 $\pm$ 2, …


Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman Jan 1988

Lessons Of The Masters: Social Tension As A Creative Necessity In The Fiction Of Hawthorne, James, And Joyce., Craig Arthur Milliman

LSU Historical Dissertations and Theses

A study of talented characters reveals that three of the most influential novelists in English dealt with the often disabling image of the artist they had inherited from their Romantic forebears by insisting on dialectical tension between the artist and society as essential to the creation of literary art. The various talented characters in Hawthorne's short fiction, such as Aylmer, Rappaccini, Oberon, the Canterbury poet, the portrait painter of "The Prophetic Pictures," the woodcarver Drowne, and Owen Warland, fail to create art unless they retain certain links with their societies of origin. This tension between artist and society appears as …


A Community Sample's Knowledge Of, Judgment Of, And Attitudes Toward Childrearing And Child Abuse., Harriet Schoenberg Williams Jan 1988

A Community Sample's Knowledge Of, Judgment Of, And Attitudes Toward Childrearing And Child Abuse., Harriet Schoenberg Williams

LSU Historical Dissertations and Theses

The present study addressed an important void in the literature of child abuse prevention. The challenge in empirical development of preventive education in child abuse to the public lies in the identification of specific target behaviors which are (1) related to potential child abuse, and (2) amenable to education. This investigation examined individual's expectations, attitudes and beliefs toward childrearing, as well as individual's knowledge of childrearing and behavioral child management techniques. Data generated in this study also evaluated the presence of differential judgments of child abuse in a community sample. Two hundred and eighty-two community volunteers participated in this study. …


Characterization Of The Pulpwood Procurement Environment Of Northwest Louisiana With A Geographic Information System., Richard William Brinker Jan 1988

Characterization Of The Pulpwood Procurement Environment Of Northwest Louisiana With A Geographic Information System., Richard William Brinker

LSU Historical Dissertations and Theses

An analysis of the pulpwood procurement environment was made to describe and model forest land area, ownership patterns, timber production, forest inventory, and the transportation network of 13 parishes in the northwest region of Louisiana. Pulpwood delivered to a pulpmill accounts for approximately 50 percent of pulp production costs. The cost of delivered pulpwood is a function of the mode of transportation, distance from the mill, competition for stumpage, and quality of the transportation network. A data base is developed from wood usage requirements, pulpmill and wood concentration yard locations, location of forested areas and their relative volumes. Areas of …


"The Trouble I'Ve Seen": Visions And Revisions Of Bondage, Flight, And Freedom In Black American Autobiography., David Lewis Dudley Jan 1988

"The Trouble I'Ve Seen": Visions And Revisions Of Bondage, Flight, And Freedom In Black American Autobiography., David Lewis Dudley

LSU Historical Dissertations and Theses

This dissertation, an historical overview of black American autobiography from Frederick Douglass to Malcolm X, examines a recurring pattern and two related themes in the genre. Ever since the escaped slave narratives established bondage, flight, and freedom as the three-part pattern of their organization, black autobiographers have employed these same elements to tell their life stories. The creation of the free "I" is the pervasive theme of black American autobiography, freedom being won and the autobiographical self established through a symbolic struggle against and victory over a powerful father figure. This figure may be the paternalistic white culture in which …


Genetics Of Callus Formation And Plant Regeneration In Rice (Oryza Sativa L.)., Qi Ren Chu Jan 1988

Genetics Of Callus Formation And Plant Regeneration In Rice (Oryza Sativa L.)., Qi Ren Chu

LSU Historical Dissertations and Theses

Callus formation and plant regeneration rates for both immature panicle and anther culture of rice were studied in several populations, including parents, F$\sb1$, F$\sb2$, F$\sb3$, and backcrossed generations. Significant genotypic differences in regeneration and callus formation rates were observed. In immature panicle culture, F$\sb1$'s generally produced rates of regeneration close to their high parents. Generation mean analysis of regeneration rates revealed the importance of dominance effects (d) and epistatic effects (aa, ad, and dd) in immature panicle culture. In contrast, production of callus by 12 F$\sb1$ hybrids in another culture was closely related to the low parents, suggesting that suppression …


Self-Referential Play Gone Wild: A Case For The "Roman Bourgeois" As Metafiction., Dianne Paula Guenin-Lelle Jan 1988

Self-Referential Play Gone Wild: A Case For The "Roman Bourgeois" As Metafiction., Dianne Paula Guenin-Lelle

LSU Historical Dissertations and Theses

The Roman bourgeois is a text which has resisted traditional modes of criticism, and thus it has confounded critics who simply did not know what to make of this hybrid work. It has been generally considered to be a novel which lacks coherence and literary merit, and spells the end of the cycle of seventeenth-century comic novels. This study proposes that the Roman bourgeois be considered as a metafictional text, where textual "anomalies" could be considered as "positive" attributes since they draw attention to the fictional framework and the fiction-making process of the novel. The novel operates according to the …


The Effects Of Linguistic And Non-Linguistic Context On The Deictic Interpretation Of Noun Phrases., Daniel George Foster Jan 1988

The Effects Of Linguistic And Non-Linguistic Context On The Deictic Interpretation Of Noun Phrases., Daniel George Foster

LSU Historical Dissertations and Theses

Definite noun phrases (NP's), proper names, and third person pronouns are not consistently interpreted deictically. Furthermore, these three types and first and second person pronouns, or potentially deictic NP's, whether deictic or not, may be interpreted as pertaining to the universe of discourse that each text creates, the situation of writing in which the text is created, or the attitudes of the writer towards the referent of a particular NP. Universe of discourse NP's include generic and descriptive NP's and those deictic in the most basic sense (i.e. those that point within the spatio-temporal field of the world external to …


Arguing Affect: The Rhetoric Of Peripheral Persuasion., Lewis Blaine Hershey Ii Jan 1988

Arguing Affect: The Rhetoric Of Peripheral Persuasion., Lewis Blaine Hershey Ii

LSU Historical Dissertations and Theses

This study explores the theoretical parameters of peripheral persuasion. Chapter one reviews social scientific approaches to the study of persuasion from researchers in communication theory, psychology, and marketing. This review reveals a bifurcation of the persuasion concept into cognitive and affective dimensions. After demonstrating a bias in social scientific research for the cognitive dimensions of persuasion, chapter one links the affective dimensions of persuasion with the concept of peripheral persuasion and emerging trends in rhetorical theory that emphasize narrative models of communication. Chapter two scrutinizes the distinction between cognitive or central routes to persuasion and affective or peripheral routes to …


Wade Hampton And The Rhetoric Of Race: A Study Of The Speaking Of Wade Hampton On The Race Issue In South Carolina, 1865-1878., Dewitt Grant Jones Jan 1988

Wade Hampton And The Rhetoric Of Race: A Study Of The Speaking Of Wade Hampton On The Race Issue In South Carolina, 1865-1878., Dewitt Grant Jones

LSU Historical Dissertations and Theses

This study examined the racial rhetoric of Wade Hampton with particular attention to claims that he was a moderate and sought to solve the racial problems of the period through rhetorical means. The study investigated: (1) the extent to which his speeches addressed the racial issue, (2) the consistency of his position, and (3) the nature and appropriateness of his appeals. State newspapers were examined to locate his speeches, which were categorized by period and subject. Examination of the data revealed four specific racial exigencies to which Hampton responded: (1) the loss of black labor (1865-66), (2) black suffrage (1867-68), …


Application Of Entropy Theory To Multivariate Hydrologic Analysis. (Volumes I And Ii)., Predrag Felix Krstanovic Jan 1988

Application Of Entropy Theory To Multivariate Hydrologic Analysis. (Volumes I And Ii)., Predrag Felix Krstanovic

LSU Historical Dissertations and Theses

This dissertation discusses the multivariate hydrologic analysis by the entropy theory. It is divided into two major parts. The first part (Volume I) examines hydrologic frequency analysis, specifically rainfall-runoff modeling and the design of rainfall networks. The second part (Volume II) develops two flood forecasting models: the univariate streamflow model, and the bivariate rainfall-runoff model. The hydrologic frequency analysis focuses on three topics: multivariate normal distribution, multivariate exponential distribution and multivariate exponential distribution and multivariate mixed distributions. Many forms of univariate, bivariate and multivariate normal distributions are derived by using the principle of maximum entropy (POME), emphasizing the serial dependency …


Adjustment Of Spouses With Caregiving Of Mentally Impaired, Physically Impaired, And Nonimpaired Elderly., Audrey Kay Sistler Jan 1988

Adjustment Of Spouses With Caregiving Of Mentally Impaired, Physically Impaired, And Nonimpaired Elderly., Audrey Kay Sistler

LSU Historical Dissertations and Theses

In this research the relationship between coping, controllability, developmental level, and subjective well-being was examined within the context of caring for an impaired spouse. Seventy-seven older persons in three different categories participated in the study: (a) individuals who cared for a mentally impaired spouse, (b) individuals who cared for a physically impaired spouse, and (c) individuals who lived with a non-impaired spouse. Results indicated that the the non-caregivers had a higher level of well-being than caregivers of the physically impaired and caregivers of the mentally impaired. Caregivers of the mentally impaired individuals sought more social support and engaged in more …


The Relevance Of Visual Models In Linguistic Theory And Discourse Analysis., Alan Dee Manning Jan 1988

The Relevance Of Visual Models In Linguistic Theory And Discourse Analysis., Alan Dee Manning

LSU Historical Dissertations and Theses

Five articles explain distinct types of linguistic phenomena with visual perception analogies. Together they give indications of similar cognitive systems underlying language and vision. First, relative numbers of languages with different basic-sentence orders for Subject, Verb, and Object fall in a hierarchy: #SOV $>$ #SVO $>$ #VSO $>$ #VOS $>$ #OVS $>$ #OSV. If syntactic interpretation parallels figure/ground interpretation and semantic form parallels enclosed visual forms then that hierarchy falls out more elegantly than in generative or functionalist explanations. Second, semantic interpretation of English syntactic form (subject NP-tense Aux-predicate VP), is modeled with the Penrose …


Effects Of Sex And Social Influence On Perception Of Physical Effort During Light To Heavy Work By Elite Athletes., Michael Francis Sylva Jan 1988

Effects Of Sex And Social Influence On Perception Of Physical Effort During Light To Heavy Work By Elite Athletes., Michael Francis Sylva

LSU Historical Dissertations and Theses

This study was designed to investigate the effect of sex and social influence on perception of physical effort during light or heavy work by male and female athletes. Subjects performed three submaximal trials of 27 minutes each on a cycle ergometer at 25, 50 and 70% of maximum oxygen consumption in the presence of a male coactor, a female coactor, and just riding alone. The results indicated that subjects' ratings of perceived exertion (RPE) were similar when performing at all three coactor/alone conditions. No significant sex difference in RPE was found. Thus, highly trained male and female atheletes did not …


Development Of A Computer-Integrated Manufacturing Simulation Model: A Hybrid Systems Approach., Vinay Kumar Vasudev Jan 1988

Development Of A Computer-Integrated Manufacturing Simulation Model: A Hybrid Systems Approach., Vinay Kumar Vasudev

LSU Historical Dissertations and Theses

The key to the successful "factory of the future" will be the effective coordination of managerial functions and production operations. The research presented in this dissertation addresses this "coordination" issue, especially in terms of understanding the impact and possibilities which exist in an information-rich environment. Such an environment is often referred to in the literature as being a computer-integrated manufacturing (CIM) environment. An interactive simulation modeling program, MOSES (Manufacturing Organization Simulation and Evaluation System), was developed for the purpose of describing, analyzing, and understanding such manufacturing. MOSES is a copyrighted computer program, a menu-driven, interactive, simulation modeling tool. MOSES users …


Construct Validity Of Depression And Anxiety In Pre-Adolescents And Adolescents: A Taxometric Approach., Michael P. Carey Jan 1988

Construct Validity Of Depression And Anxiety In Pre-Adolescents And Adolescents: A Taxometric Approach., Michael P. Carey

LSU Historical Dissertations and Theses

The similarities and differences of the response classes of depression and anxiety were investigated with a sample of pre-adolescents and adolescents. The subjects were 412 pre-adolescents and adolescents from a local public school and a local psychiatric hospital. All of the participants were administered a battery of self-rating on two consecutive days. Two self-ratings of depression and two anxiety measures were utilized in order to adequately sample the content domains. Additionally, self-ratings were used to assess nine related response classes (i.e, fears, social skills, major life events, activity, hopelessness, depressed mood, anxious mood, parent-adolescent conflict, and dysfunctional thoughts). All assessment …
