From The Shadow Of Reagan: George Bush And The End Of The Cold War., Christopher Alan Maynard Jan 2001

From The Shadow Of Reagan: George Bush And The End Of The Cold War., Christopher Alan Maynard

LSU Historical Dissertations and Theses

George Bush entered the presidency constantly compared and contrasted with his predecessor, Ronald Reagan. Lacking Reagan's eloquence and adept use of the media, Bush was lambasted by the press as Reagan's "lapdog" and labeled a "wimp." The press pushed Bush to establish themes to match policy goals and to use the bully pulpit to lead the national debate on issues. His refusal prompted journalists to characterize the Bush presidency as lacking an agenda. Reagan's success with the media and Bush's failure have produced a misconception about the successes and failures of each president's policies. Thus, the period usually is referred …

Theatre At Caffe Cino: The Aesthetics And Politics Of Revolt, 1958--1968., Wendell Corbin Stone

LSU Historical Dissertations and Theses

Often considered the first off-off-Broadway theatre, Caffe Cino opened in December 1958 on a quiet street in New York's Greenwich Village. As proprietor Joseph Cino later explained, his goal was to provide a venue in which friends could enjoy coffee, conversation, and artistic events (including lectures, art displays, poetry readings, and play readings). Because of their popularity, the play readings quickly developed into fully-staged performances and supplanted all other artistic endeavors. By the early 1960s, the Caffe offered a demanding production schedule, with performances at 9:00 p.m. and 11:00 p.m. every day and additional performances at 1:00 a.m. on the …

Toward A Reconceptualization Of The Integration Of Culture And Language In The Korean Efl Classroom., Seung Bin Roh Jan 2001

Toward A Reconceptualization Of The Integration Of Culture And Language In The Korean Efl Classroom., Seung Bin Roh

LSU Historical Dissertations and Theses

Many Korean EFL (English as a Foreign Language) students do not have sufficient opportunity to learn cultural knowledge and information in their classrooms. EFL teachers also tend to ignore the teaching of culture. Even though culture is taught, it simply delivers "fact-only" information rather than cultural awareness by comparing native with target culture. Teaching target cultural knowledge and information should be delivered within the native cultural frame, and teaching of culture must be an integral part of teaching and learning English. For the effective integration of culture in EFL classes apart from conveying simply "fact-only" information, this research advocates the …

Indium Arsenide/Gallium Arsenide Quantum Dots And Nanomesas: Multimillion-Atom Molecular Dynamics Solutions On Parallel Architectures., Xiaotao Su Jan 2001

Indium Arsenide/Gallium Arsenide Quantum Dots And Nanomesas: Multimillion-Atom Molecular Dynamics Solutions On Parallel Architectures., Xiaotao Su

LSU Historical Dissertations and Theses

Multimillion-atom molecular dynamics (MD) simulations have been performed to study the flat InAs overlayers with self-limiting thickness on GaAs square nanomesas. The in-plane lattice constant of InAs layers parallel to the InAs/GaAs(001) interface starts to exceed the InAs bulk value at 12th monolayer (ML) and the hydrostatic stresses in InAs layers become tensile above ∼12 th ML. As a result, it is not favorable to have InAs overlayers thicker than 12 ML. This may explain the experimental findings of the growth of flat InAs overlayers with self-limiting thickness of ∼11 ML on GaAs nanomesas. We have also examined the lateral …

The Geometry Of Electronically -Excited States: Vibronic Intensity Distributions And Bond Length Changes., Dorothy Marie Wood Jan 2001

The Geometry Of Electronically -Excited States: Vibronic Intensity Distributions And Bond Length Changes., Dorothy Marie Wood

LSU Historical Dissertations and Theses

An exact power series expression has been obtained for the Franck-Condon integral (FCI) in the harmonic approximation. This expression is a function of a parameter Delta where Delta → 0 as the frequencies of vibration in the two combining electronic states approach equality. These two characteristics, that of a power series in Delta and the fact that Delta → 0 in certain situations, permit truncation of various functions involving FCI's. Such truncation was performed for the ratio S2v'0'' /S2v'-1 0'' , where the S2v'v'' are the FCI's, and the subscripts, in the usual notation, denote the vibrational quantum numbers in …

Robust Control Of Uncertain Time -Delay Systems., Yun-Ping Huang Jan 2001

Robust Control Of Uncertain Time -Delay Systems., Yun-Ping Huang

LSU Historical Dissertations and Theses

Time-delay systems are common in industries. Direct analysis and synthesis of control systems with time delays are complicated and approximation methods such as Pade approximation are usually applied. However, the issues of control system robustness with respect to model uncertainties and approximation errors have not been sufficiently addressed. This dissertation focus on robustness of time-delay systems, especially robustness with respect to time delays, which has been discussed extensively using Lyapunov second method. We propose two methods in this dissertation to reformulate the problems into standard mu or Hinfinity problems. The first method involves representing the systems in linear functional transformation …

The Effect Of Calcium Silicate On Rice Yield And Sheath Blight Disease., Chris Raymond Robichaux Jan 2001

The Effect Of Calcium Silicate On Rice Yield And Sheath Blight Disease., Chris Raymond Robichaux

LSU Historical Dissertations and Theses

Sheath blight caused by fungal pathogen Rhizoctonia solani can cause significant yield loss in rice, especially in warm, high rainfall environments. Integrated pest management (IPM) is the key to sheath blight control. This system utilizes disease resistance, pesticides, cultural practices and biological control to control multiple pests. Silicon fertilization is an additional cultural practice that can reduce sheath blight severity and increase grain yield. Studies were conducted in the greenhouse and field to determine the effect of calcium silicate on sheath blight severity, rice grain yield, and leaf silicon concentration. Results in the greenhouse study showed that sheath blight severity …

Soil Management In Two Highland Guatemalan Municipios: Local Perspectives On The Management And Degradation Of Soil Resources., Steven James Rainey Jan 2001

Soil Management In Two Highland Guatemalan Municipios: Local Perspectives On The Management And Degradation Of Soil Resources., Steven James Rainey

LSU Historical Dissertations and Theses

This dissertation studies how small farmers of two ethnic groups manage the soil resource in a portion of Highland Guatemala that is considered marginal for crop production due to steep slopes. In the past, various groups concerned about environmental degradation tended to blame peasant farmers such as these for degrading the land resource through "primitive and backward" agricultural practices and a general lack of knowledge of the consequences of their actions. Yet attempts to convince small farmers to adopt new techniques have often failed due in part to an inadequate knowledge of local conditions and to a failure to recognize …

Some Technical Vocabulary Of Rhetorical Invention In The Treatise Of Anonymous Seguerianus, Hermogenes' "On Statis", And Book Three Of The [Pseudo-]Hermogenic Work "On Invention", Mark Allen Williams

LSU Historical Dissertations and Theses

From the debates of the Christian councils to the homilies of the local priests, from the opaque scripting of the Byzantine epistle to the clarities of stasis theory, from the entertaining fictions of declamation to the promulgation of Byzantine cannon law, the citizens of Byzantium were never far from the rhetorical, and they themselves knew it. But the development of rhetorical theory in the Greek West has gained little attention, and what has been given to it has generally concentrated on questions of style. This dissertation examines some of the most basic qualities of that theory of rhetorical invention which …

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds

LSU Historical Dissertations and Theses

To address the role of parasites on subsequent antigenic challenge, humoral, lymphoproliferative and cytokine responses to a single intramuscular injection of keyhole limpet haemocyanin (KLH) were compared between groups of ponies with high, medium or low gastrointestinal parasite burdens. Heavy and moderately parasitised animals showed a trend towards reduced KLH-specific lymphoproliferation and reduced antigen specific total immunoglobulin, IgG(T) and IgA compared to lightly parasitised ponies. The peripheral blood mononuclear cells (PBMC) from medium and heavily parasitised ponies also had significantly lower levels of IL-4. These data indicate that heavily parasitised animals have uniformly decreased cellular and humoral immune responses to …

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire Jan 2001

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire

LSU Historical Dissertations and Theses

The Great White Heron was originally described as a distinct species (Ardea occidentalis), but is currently considered to be the white morph of a polymorphic Great Blue Heron subspecies (A. herodias occidentalis). Great White and Great Blue heron breeding ranges overlap in the Florida Keys (USA), providing an opportunity to evaluate the degree to which these two taxa are reproductively isolated. The current classification leads to predictions of no significant size difference (H01), random mate choice (H02), and no genetic divergence (H03) between sympatric white and blue herons. Sympatric Great White and Great Blue herons did not differ significantly in …
