Flesh And Spirit Onstage: Chronotopes Of Performance In Medieval English Theatre, Gregory Lee Cavenaugh

LSU Doctoral Dissertations

This study uses Mikhail Bakhtin's chronotope, which is the informing principle of one's experience of space and time, to explore different relations among space, time, actors, and audience in medieval theatre. Relations between the material and spiritual worlds as understood in the Middle Ages are considered in the context of relations between performers and audience members with two goals. First, I explore how the ontological status of the metaworld created through performance changed in the context of specific chronotopes. Second, I explore how diverse religious discourses affected medieval modes of representation. This study posits three chronotopes of performance informing medieval …


A Theory Of Effective Computer-Based Instruction For Adults, Janis Sue Lowe Jan 2004

A Theory Of Effective Computer-Based Instruction For Adults, Janis Sue Lowe

LSU Doctoral Dissertations

Computer-based instruction (CBI) was considered the technological phenomenon to revolutionize education and training. Today, the Internet and computer technology are reported to have significantly altered the education landscape (Johnson & Aragon, 2002). The rapid advances in technology, the need for lifelong learning, and the growth of non-traditional students have encouraged the use of the computer as a method of instructional delivery. Evaluating the effectiveness of CBI as a whole technology is very difficult. The inability to measure effectiveness is attributable in part to the fact that CBI is not just one component, but a complex range of services and activities …

Modeling The Hydrologic And Particulate Loadings From Paved Urban Surfaces, Chad Michael Cristina Jan 2004

Modeling The Hydrologic And Particulate Loadings From Paved Urban Surfaces, Chad Michael Cristina

LSU Doctoral Dissertations

This dissertation details the results of recent investigations concerning non-colloidal particulate matter found in urban rainfall-runoff and urban snowmelt. Three forms of the power law model (PLM) were used to model particle number density. It was found that significant model error could be introduced into PLMs when the median diameter particle was used to estimate the number of particles per interval, but the SSE of continuous PLMs could be significantly reduced through the use of correction factors when the sieve interval was large (P<0.05). Additionally, a multiple PLM analysis may be more appropriate than a single PLM analysis when changes in particle population occur within a single gradation. PLMs were also used to model the relationship between cumulative granulometric mass and cumulative particulate-bound metal mass. The use of such calibrated PLMs provided considerable cost reduction when compared to conventional direct measurements of particulate-bound metal mass. A first flush analysis indicated that only events with average volumetric flow rates approaching 1 L/min/m of drainage width exhibit a rapid depletion of particulate matter consistent with the concentration-based definition of the first flush. An analysis of particle separation mechanisms indicated that 90% of these particles, by mass, could be removed from the discharge with detention times of 30 min and 120 min for snowmelt and rainfall-runoff, respectively, in a typical roadside drainage system. It was also found that the kinematic wave model could accurately model significant aspects of rainfall-runoff events in traffic-impacted watersheds provided that abstractions were incorporated into the modeling process. For this watershed the source of abstraction was attributable to vehicular traffic. For high-intensity events with more than 10 vehicles per runoff volume (VPV) the runoff coefficient varied between 0.6 and 0.9 while for low-intensity events with fewer than 10 VPV the coefficient ranged between 0.2 and 0.4.

The Chick Embryo Amnion As An In Vitro Culture System For Ivf And Nt Embryos, Tonya Renea Davidson

LSU Doctoral Dissertations

Calving rates are significantly reduced following in vitro production of embryos. Thus, if a technique could be developed that would increase calving rates by as little as one viable offspring, significant research advances could be made. Therefore, in a series of experiments, the efficiency and quality of culturing IVP bovine embryos in the amnion of a domestic chicken egg was tested. In Experiment I, by culturing IVP bovine embryos in the chick amnion (day 4 to 7 of incubation) it was discovered that there was no significant difference in blastocyst rates compared with controls. In Experiment II, it was shown …


Transfer Functions Of Streptomyces Plasmid Pij101: Insights Into A Novel Bacterial Conjugation System, Matthew John Ducote Jan 2004

Transfer Functions Of Streptomyces Plasmid Pij101: Insights Into A Novel Bacterial Conjugation System, Matthew John Ducote

LSU Doctoral Dissertations

For Streptomyces plasmid pIJ101 to mediate DNA transfer, only the clt locus and the Tra protein are required, though three non-essential spread functions increase the radial distance of plasmid dissemination among recipients after the initial lateral transfer event. clt is a contiguous 54-bp sequence within an intrinsically curved plasmid region that contains inverted and direct repeats; biochemical and genetic methods described here indicate that single-stranded cleavage reminiscent of most conjugative plasmids does not occur at clt. clt therefore likely promotes plasmid transfer by interacting with the pIJ101 Tra protein or host-encoded factors in a transient, novel DNA-processing event or by …


Soils Of Regeneration: Exploring Conceptualizations Of The Natural World As A Context For An Ecologically-Sensitive Curriculum, Emily A. Demoor Jan 2004

Soils Of Regeneration: Exploring Conceptualizations Of The Natural World As A Context For An Ecologically-Sensitive Curriculum, Emily A. Demoor

LSU Doctoral Dissertations

David Orr (1994) asserts that the ecological crisis is a crisis of education. This study explores the relationship between the ecological crisis and education by examining the role that language plays in shaping perceptions of the natural world. Toward this end it analyzes narratives of science, literature and other disciplines that conceptualize the natural world as object and as subject. It evaluates how particular metaphors used in reference to the natural world enhance or impede ecological understanding and the cultivation of responsibility and stewardship and considers ways in which these conceptualizations might be used as a basis for new curriculum …

Thermodynamic Characterization Of Dna Binding By Type I Dna Polymerases From Thermus Aquaticus And Escherichia Coli, Kausiki Datta Jan 2004

Thermodynamic Characterization Of Dna Binding By Type I Dna Polymerases From Thermus Aquaticus And Escherichia Coli, Kausiki Datta

LSU Doctoral Dissertations

DNA binding of the DNA polymerase I from Thermus aquaticus (Taq and Klentaq fragment) and E. coli (Klenow fragment) have been studied as a function of [salt] and temperature in order to understand their DNA binding thermodynamics. Binding of the two different species of polymerases occurs with sub-micromolar affinities in very different salt concentration ranges. Thus, at similar [KCl] the binding of Klenow is ~ 3kcal/mol (150X) tighter than the binding of Taq/Klentaq. Linkage analysis of the [KCl] dependence of DNA binding at 25°C reveals a net release of 2-3 ions for Taq/Klentaq and 4-5 ions for Klenow. DNA binding …


Against Biopoetics: On The Use And Misuse Of The Concept Of Evolution In Contemporary Literary Theory, Bradley Bankston Jan 2004

Against Biopoetics: On The Use And Misuse Of The Concept Of Evolution In Contemporary Literary Theory, Bradley Bankston

LSU Doctoral Dissertations

This dissertation is a critical assessment of "biopoetics:" a new literary theory that attempts to import ideas from evolutionary science to the study of literature. Borrowing from the field of evolutionary psychology, the biopoeticists argue that some literary forms and themes are particularly valuable because they result from our innate and evolved cognitive structure; they also attempt to create a normative aesthetic from the idea that evolution is progressive. In its first half, this study examines the claims of evolutionary psychology and their application by the biopoeticists; in the second half, it examines the idea that evolution is progressive, and …

Protein Aggregation Studies: Inhibiting And Encouraging Β-Amyloid Aggregation, Jed Paul Aucoin Jan 2004

Protein Aggregation Studies: Inhibiting And Encouraging Β-Amyloid Aggregation, Jed Paul Aucoin

LSU Doctoral Dissertations

This work demonstrates peptide-based aggregation mediation of fibril forming peptides, notably β-amyloid (1-40), Aβ1-40. To achieve the goals of this work, Aβ1-40 aggregation was governed by ionic strength, temperature, and pH. After controlling and reproducing Aβ1-40 aggregate formation (fibrils), each peptide-based aggregation mediator was evaluated for its ability to self-aggregate and to possess surface-active properties. The incorporation of these mediators in Aβ1-40 solutions changed the surface tension and produced aggregate complexes of mediator and Aβ1-40. Evidence that Aβ1-40 fibril formation may be mediated by disorder-to-order transitions has been observed by layer formation …
