Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell Jan 1992

Jeremy Rifkin Challenges Recombinant Dna Research: A Rhetoric Of Heresy., Wiley Michael Futrell

LSU Historical Dissertations and Theses

Western culture, in large part, is a product of scientific inquiry, technological development and the ability to harness some of nature's resources. Much of society looks to science for technology-related solutions to many of its ills. As it develops new technology, science necessarily seeks to understand and control the forces of nature. Although science assumes a prominent role in contemporary society, that prominence does not necessarily translate into cultural consensus on the progress achieved by technological developments. Another perspective is represented by those who contend that continued technological advancement is the source of existing problems, not the solution. As these …

Three Essays In Dividend Policy., Jaisik Gong Jan 1992

Three Essays In Dividend Policy., Jaisik Gong

LSU Historical Dissertations and Theses

This dissertation focuses on three leading theoretical and empirical issues in the anomaly of dividend policy. The first essay analyzes the explanatory power of the various theories of dividend determinants, many of which have not been tested yet. In this essay, time-series cross-sectional tests are undertaken using individual firm data, while the structural vector autoregressive (VAR) methodology is applied to the aggregate data. The second essay proposes an alternative approach to the ex-dividend anomalies that fully incorporates both the tax-effect hypothesis and the short-term trading hypothesis. This approach draws on normative portfolio selection models to examine the relationships between the …

The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett Jan 1992

The Rhetoric Of Synnationalism: A Model Of Foreign Policy Discourse., Ralph A. Hamlett

LSU Historical Dissertations and Theses

The United States, as other nation-states, claims legitimacy as an agency for the expression of the aspirations of its people. This political structure appeared as part of a historical process that implied a transfer of authority from ruling elite(s) to the public. However, U.S. foreign policy discourse evidences an incomplete relocation of authority. In matters of sovereignty and national interests, the policy establishment considers itself more capable of decisions than ordinary people. The establishment tends to view citizens as masses disinterested in and incapable of understanding vital decisions of the state. The policy establishment assumes the public's role is best …

A Comparison Of The Physiological Responses Of Brain-Damaged Alcoholics, Nonbrain-Damaged Alcoholics, And Social Drinkers To The Smell Of Alcohol., Fredric D. Klug Jan 1992

A Comparison Of The Physiological Responses Of Brain-Damaged Alcoholics, Nonbrain-Damaged Alcoholics, And Social Drinkers To The Smell Of Alcohol., Fredric D. Klug

LSU Historical Dissertations and Theses

This study reviews the relapse prevention and neuropsychological literature relevant to alcoholism. The argument was made that impaired neuropsychological functioning may be an important determinant of relapse. Specifically, neuropsychological impairment was expected to affect the manner in which individuals respond to conditioned alcohol cues so as to increase their attention to the cues and increase their desire to drink, a process which might adversely affect recovery. In order to study the impact of conditioned alcohol cues, subjective, objective, and psychophysiological responses of brain-damaged alcoholics, nonbrain-damaged alcoholics, and nonbrain-damaged social drinkers were compared on their responses to alcohol and to water. …

Cell-Mediated Immune Response To Equine Infectious Anemia Virus., Deborah Franklin Lea Jan 1992

Cell-Mediated Immune Response To Equine Infectious Anemia Virus., Deborah Franklin Lea

LSU Historical Dissertations and Theses

The lentivirus Equine Infectious Anemia Virus (EIAV) causes an acute infection in horses which is characterized by fever, viremia, thrombocytopenia, edema, and hemolytic anemia. Most horses survive the acute disease, but remain persistently infected for life. The exact mechanism whereby horses' control their initial infection is unknown, though it appears likely that cellular immune mechanisms are involved. T lymphocytes have been shown to play a major role in the recovery from a variety of viral infections, though their role in EIAV infection has not been established. We tested peripheral blood mononuclear cells (PBMC) from EIAV-infected ponies for evidence of a …

A Formal Methodology For The Specification Of Distributed Systems From An Object Perspective., Sangbum Lee Jan 1992

A Formal Methodology For The Specification Of Distributed Systems From An Object Perspective., Sangbum Lee

LSU Historical Dissertations and Theses

Distributed computing systems are systems in which multiple processors run independently by communicating with each other. The design of distributed systems is difficult to achieve as the execution patterns of distributed system are typically more complex than those of non-distributed computing systems. The application of object-oriented techniques to the design of distributed systems has the potential to increase the power of modeling and computing. A formal methodology which includes a specification language, developed from an object perspective, for the development of distributed systems is presented. The formal specification language, DOSL (Distributed Object-based Specification Language), represents the specification of distributed systems …

Bibl. Nat. Ms. Fr. 379: A Study In Word And Image. (Volumes I And Ii)., Adelaide Stuart Frazier

LSU Historical Dissertations and Theses

The Bibl. Nat. ms. fr. 379 offers a religious, social, literary and artistic comment on the implications of the early sixteenth century world. The cult of the Virgin is considered as it supported and directed the poetry contests or puy at Rouen and Dieppe in their particular emphases on the Immaculate Conception and the Assumption of the Virgin, both ideas more dogmatic than scriptural. The conduct of the puy controlled the literary and artistic expressions on the subject. A detailed discussion submits the evidence that the poets reflected the secular world in their poems and the artists' illustrations often rejected …

The Relation Between Stress And Insulin-Dependent Diabetes Mellitus: Physiologic Arousal Or Disruption Of Compliance?, Virginia Diane Garrett Jan 1992

The Relation Between Stress And Insulin-Dependent Diabetes Mellitus: Physiologic Arousal Or Disruption Of Compliance?, Virginia Diane Garrett

LSU Historical Dissertations and Theses

The relations between minor life events, compliance, urinary free cortisol, and blood glucose in 40 adults with insulin-dependent diabetes mellitus was examined. Specifically, this study explored whether naturally-occurring minor stressful events had disruptive effects on metabolic control through: (a) an arousal mechanism mediated by cortisol, (b) disruption of the individual's adherence to prescribed treatment, (c) a combination of arousal and disruption of compliance, or (d) a third, unspecified mechanism. Stress did not influence metabolic control, either independently or via a stress-compliance or stress-arousal mechanism although stress was related to cortisol activity. Neither the direct effects of cortisol nor a cortisol …

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford Jan 1992

Incorporating Reservoir Characteristics For Automatic History Matching., Keith J. Halford

LSU Historical Dissertations and Theses

Automatic history matching is refined in this work by expanding the objective function and incorporating reservoir characteristics in the process of parameter selection. Iso-value contours are used to incorporate reservoir characteristics within history-matching parameters. These improvements are implemented in an automatic history-matching algorithm, OPTIM, that is coupled with BOAST II. Case histories of both hypothetical and real reservoirs demonstrated the effectiveness of incorporating reservoir characteristics in automatic history-matching parameters.

Recovery Of Sugars From Cane Molasses By Continuous Simulated Moving Bed Ion-Exclusion Chromatography., Khalid Iqbal Jan 1992

Recovery Of Sugars From Cane Molasses By Continuous Simulated Moving Bed Ion-Exclusion Chromatography., Khalid Iqbal

LSU Historical Dissertations and Theses

Present investigation was undertaken to determine the feasibility of using a Simulated Moving Bed (SMB) Ion Exclusion Chromatographic system for the recovery of sugars from molasses. The recovery of sugars from molasses is complicated because of the presence of high concentration of salts of K, Ca, Mg, etc. The presence of these salts in the molasses prevents sucrose to crystallize. SMB Ion Exclusion Chromatography has been shown to be successful to recover sugars from beet molasses, and to separate sugars from each other in High Fructose Corn Syrup industry. The basis of the ion exclusion is that the sorbent used …

Improvement Of The Data Analysis Algorithm By Applying The Decision Tree Method., Won Chan Jung Jan 1992

Improvement Of The Data Analysis Algorithm By Applying The Decision Tree Method., Won Chan Jung

LSU Historical Dissertations and Theses

Data analysis (reconstructability analysis) is an area used on a data set which has several variables and a function value to find the most important factor that causes the function values to fall within a desired range. Normal data analysis algorithm (1) finds the most important factor in O (2$\sp{n})$ time. This dissertation introduces a newly developed system of algorithms called the Data Analyzing Tree (DAT) which is designed to either reduce the time complexity or produce more accurate results. DAT-1 uses O $(n\sp2)$ time to produce the same results as the normal data analysis method, and DAT-2 produces the …

A Study Of The Differences In Induction Experiences For Teachers In Differentially Effective Schools., Carol Sue Ter Haar Jan 1992

A Study Of The Differences In Induction Experiences For Teachers In Differentially Effective Schools., Carol Sue Ter Haar

LSU Historical Dissertations and Theses

Research studies have concluded that many new teachers abandon their teaching careers shortly after starting them. Part of the reason is their lack of adjustment within the very special social structure of public education. Induction of teachers frequently appears to be inadequate. Research over the past 20 years suggests a correlation between positive induction experiences and the quality of schools. This causal comparative study entailed a 3 x 2 design with three levels of school effectiveness and two levels of teacher experience. The schools were classified as effective, typical, or ineffective based on a classification scheme produced by the Louisiana …

Stratigraphic Architecture Of An Extensional Orogen: The Mojave Extensional Belt, Southern California., Christopher John Travis

LSU Historical Dissertations and Theses

Field-based studies and quantitative models provide new insights into the stratigraphic architecture of a developing continental extensional orogen. The early Miocene age Mojave Extensional Belt of southern California (MEB) exhibits a tripartite stratigraphy, consisting of (1) pre- to early synextension volcanic deposits, unconformably overlain by (2) syntectonic basement-derived megabreccia and breccia with local finer-grained units, overlain by (3) a posttectonic fining-upward sequence of gravel, sand, shale, and limestone. On a more local scale, stratigraphy and sediment dispersal within the MEB reflect the evolution of the major tectonic elements of the belt: (1) Breakaway zone. Strata of the western Newberry Mountains …

The Stability Of Thick, Self-Gravitating Disks In Protostellar Systems., John William Woodward Jan 1992

The Stability Of Thick, Self-Gravitating Disks In Protostellar Systems., John William Woodward

LSU Historical Dissertations and Theses

We perform a computational survey of the stability of protostellar systems which contain a self-gravitating disk. The systems are initially represented by a point mass $M\sb{c}$ at the center and a geometrically thick, axisymmetric disk of mass $M\sb{d}$ that supports uniform specific angular momentum and obeys an n = 3/2, polytropic equation of state. The equilibrium disk structure is uniquely defined upon the specification of two key dimensionless system parameters: $M\sb{d}/M\sb{c}$ and $T/\vert W\vert$ (the ratio of rotational kinetic energy of the disk to the gravitational potential energy of the system). The focus of this work is the identification of …

The Purification Of Mcrb And Mcrc Proteins In Mcrbc Restriction System Of Escherichia Coli K12 And Dna Sequencing Of The Region Downstream Of Mcrc., Ling Zheng Jan 1992

The Purification Of Mcrb And Mcrc Proteins In Mcrbc Restriction System Of Escherichia Coli K12 And Dna Sequencing Of The Region Downstream Of Mcrc., Ling Zheng

LSU Historical Dissertations and Theses

The McrBC restriction system of Escherichia coli K12 degrades methylcytosine-containing foreign DNA. Two genes mcrB and mcrC had been shown to be required for the McrBC restriction (Ross, et al., J. Bacteriol., 1989b). To explore the involvement of additional gene(s), a 1.7 kb fragment downstream of the mcrC was cloned and sequenced. Also mutants containing deletion in mcrBC or the downstream region were isolated by transposon excision. Genetic complementation studies confirmed that only DNA containing mcrB and mcrC gene on a high copy plasmid were needed to fully restored McrBC restriction. Deletion of the 1.7 kb fragment from or addition …

The Rhetoric Of Redemption: A Development Of Kenneth Burke's Theory Of Guilt-Purification-Redemption And Its Application To Martin Luther King, Jr.'S "I Have A Dream" Speech., David A. Bobbitt Jan 1992

The Rhetoric Of Redemption: A Development Of Kenneth Burke's Theory Of Guilt-Purification-Redemption And Its Application To Martin Luther King, Jr.'S "I Have A Dream" Speech., David A. Bobbitt

LSU Historical Dissertations and Theses

This dissertation presents an exposition and development of Kenneth Burke's theory of guilt-purification-redemption (also referred to as the "redemption drama"), and then an application of that theory through a critical analysis of Martin Luther King, Jr.'s "I Have a Dream" speech. King's speech is treated as the "representative anecdote" of the moderate wing of the first phase of the civil rights movement. The speech became an authorizing text on race relations and provided the movement with an articulation of its logic and narrative form. Usually Burke's theory is seen as positing two primary modes of purification of guilt: victimage and …

Centralization And Decentralization: The Relationship Of Bureaucracy, Autonomy And The Principalship In Elementary Schools., Cheryl Berot Boutte

LSU Historical Dissertations and Theses

Throughout the last decade, parents and communities have continued to press for more control over their schools in an attempt to improve performance. Members of the educational community have begun calling for school restructuring to return decision making power to the school site professionals. These calls for the decentralization of our highly centralized school systems have prompted educators, researchers and political scientists to examine the organizational settings in which schools operate. This study investigated the influence of organizational structure, namely centralized bureaucracy and decentralized autonomy on school leadership and the relationship of that leadership to the school's culture. The study …
