Reflections Of Science And Technology In American Drama From 1913 To 1941., Charles Keith Cockrell

LSU Historical Dissertations and Theses

The growth of science and technology exploded in the first half of the twentieth century. At the same time America was developing for the first time a dramatic literature that was worthy of international respect. Beginning in 1913, when the young Eugene O'Neill wrote his first plays, this study traces the appearances of science and technology in the drama from that year until the start of World War II. Special attention has been given to the clock, the car, electronic communications, scientists, dehumanization in the machine age, technology as religion, and film. The drama of the era reveals a previously …

Null Codon-Based Models Of Synonymous And Nonsynonymous Substitution From A Phylogenetic Perspective., David A. Mcclellan

LSU Historical Dissertations and Theses

This dissertation focuses on the relationship between codon composition and the molecular evolution of protein-coding DNA sequences. Chapter 1 emphasizes the role of codon structure in determining patterns of nucleotide substitution, as well as the influence codon composition has on the evolution of the structure and function of the protein. The overall purpose of Chapter 1 is to establish the need to study molecular evolution at the codon level. In Chapter 2, the codon-degeneracy model (CDM) of molecular evolution is constructed. This model considers codon structure in terms of patterns of nucleotide site degeneracy. It allows the prediction of patterns …

The Names Project Aids Memorial Quilt: A Novelistic Approach To Decoding The Layers Of Meaning In The "Pieced" Social Drama., Louis Edward Myers

LSU Historical Dissertations and Theses

In this study, I focus on the AIDS crisis as a social drama, and evaluate the various functions the AIDS Memorial Quilt plays within that drama. Using Victor Turner's concept of social drama I first discuss the breach, crisis, redression, and reintegration stages. I identify two fundamental breaches in the AIDS drama---the health breach and the moral/religious breach. As regards the crisis phase of the drama, I identify specific crisis performers and performances. Although many attempts were made at redression, I conclude that most attempts were not successful as redressive acts. Rather than "solve" or "set straight" particular issues within …

Spatial Modeling Of Coastal Landscapes: Methodological And Scientific Applications., Mary Louise White

LSU Historical Dissertations and Theses

A number of issues related to landscape scale ecological modeling of the wetlands of southern Louisiana are examined in this study. First, using geostatistical methods, a new contour map of the wetland habitats in the Terrebonne basin of southern Louisiana is constructed from data collected in 1994. This map is proposed as the best field verified habitat map of the Terrebonne basin and contains statistical confidence intervals associated with the habitat contours. Second, the problem of how to evaluate the success of a landscape model prediction is investigated. The multiple resolution goodness of fit parameter Ft(k) is evaluated in detail …

Restructuring Object -Oriented Designs Using A Metric-Driven Approach., Ghassan Salim Alkadi

LSU Historical Dissertations and Theses

The benefits of object-oriented software are now widely recognized. However, methodologies that are used to develop object-oriented software are still in their infancy. There is a lack of methods to assess the quality of the various components that are derived during the development process. The design of a system is a crucial component derived during the system development process. Little attention has been given to assessing object-oriented designs to determine the goodness of the designs. There are metrics that can provide guidance for assessing the quality of the design. The objective of this research is to develop a system to …

Enhancing The Process Of Testing Object -Oriented Systems., Ihssan Salim Alkadi

LSU Historical Dissertations and Theses

Testing is a crucial step in the overall system development process. Using testing techniques that support features of the underlying software paradigm more effectively tests program than do testing techniques that support features of other paradigms. Systems developed with the object-oriented paradigm require techniques that support object-oriented features such as inheritance, data abstraction, encapsulation, and dynamic binding. Many techniques that are used to test systems developed with the structured paradigm are not sufficient for the testing of object-oriented systems. The goal of this research is to develop methods that will improve the process of testing object-oriented systems. Specifically, emphasis is …

Looking For Leadership: Searching In A Middle School For Reactions To Stimuli In Social Environments., Lucy Gremillion Begnaud

LSU Historical Dissertations and Theses

Leadership development lies at the heart of establishing a meaningful legacy for students. More important than subject matter and curriculum content, the affective traits we instill in our students will guide them. Such traits are at the core of leadership development, the focus of this qualitative research case study. An eight-month immersion in a fifth grade gifted enrichment program addressed the following questions: (a) What leadership opportunities do students have in a gifted enrichment program at the fifth grade level? (b) What could enrichment programs do to foster leadership development in their gifted students? Four themes emerged during this study: …

Powerless Speech: The Effects Of Gender, Gendered Intensifiers, And Attitudes Toward Women On Speaker Credibility., Frances E. Brandau-Brown

LSU Historical Dissertations and Theses

The purpose of this study was to examine powerful and powerless speech styles in relation to sex of speaker, sex of respondent, and attitudes toward women. Based on research by Bradac, Mulac, and Thompson (1995) it was proposed that the powerless speech style variable, intensifiers, could be divided into separate masculine and feminine domains. The Attitude Toward Women scale was used to classify respondents as either liberal or traditional. From this classification predictions were made using Expectancy Violation Theory to formulate a priori hypotheses about respondent perceptions of speaker competence, trustworthiness, and masculinity. Multivariate, univariate and post-hoc tests revealed that …

Apples And Regional Change: Life And Economy In Tsugaru, Japan., Ann D. Brucklacher

LSU Historical Dissertations and Theses

In this dissertation, I examine aspects of Japan's rural and agricultural restructuring using Aomori Prefecture's apple industry as a focal point. Though using multiple spatial scales, I concentrate most on changes in agriculture and economy in the Tsugaru region, Aomori's main apple-growing region. A historical overview of Tsugaru and its apple industry provides the background necessary for understanding today's circumstances. Archival and ethnographic methods examine modern-day changes and document the views of individual farmers and their families. Located at the northwestern-most tip of Japan's main island, the Tsugaru region was historically one of Japan's most remote and impoverished regions. The …

Impact Of Shrimp Imports On The United States' Southeastern Shrimp Processing Industry And Processed Shrimp Market., Hamady Diop

LSU Historical Dissertations and Theses

The shrimp harvesting sector is the largest component of the southeastern United States fishing industry, accounting for 57% of the total value of landings in the region in 1996. U.S. shrimp imports were valued at $2.6 billion in 1996. Together, domestic production and imports of the raw product support a large shrimp processing sector, which provides several thousand jobs either directly or indirectly. In 1975 and 1984, the United States International Trade Commission (USITC) investigated the industry to determine whether the volume of shrimp imports was high enough to threaten domestic firms which were producing articles similar to, or directly …

Isolation Of A Highly Active Photosystem Ii Preparation From Synechocystis 6803 Using A Histidine-Tagged Mutant Of Cp 47, Terry M. Bricker, Jason Morvant, Najy Masri, Holly M. Sutton, Laurie K. Frankel

Faculty Publications

Site-directed mutagenesis was used to produce a Synechocystis mutant containing a histidine tag at the C terminus of the CP 47 protein of Photosystem II. This mutant cell line, designated HT-3, exhibited slightly above normal rates of oxygen evolution and appeared to accumulate somewhat more Photosystem II reaction centers than a control strain. A rapidly isolatable (<7 >h) oxygen-evolving Photosystem II preparation was prepared from HT-3 using dodecyl-β-d-maltoside solubilization and Co2+ metal affinity chromatography. This histidine-tagged Photosystem II preparation stably evolved oxygen at a high rate (2440 μmol O2 (mg chl)-1 h-1), exhibited an α-band absorption maximum at 674 nm, …

Exact Relations For Effective Tensors Of Polycrystals. Ii. Applications To Elasticity And Piezoelectricity, Yury Grabovsky, Daniel S. Sage

Faculty Publications

An important necessary condition for an exact relation for effective moduli of polycrystals to hold is stability of that relation under lamination. This requirement is so restrictive that it is possible (if not always feasible) to find all such relations explicitly. In order to do this one needs to combine the results developed in Part I of this paper and the representation theory of the rotation groups SO(2) and SO(3). More precisely, one needs to know all rotationally invariant subspaces of the space of material moduli. This paper presents an algorithm for finding all such subspaces. We illustrate the workings …

Mycobacterium Avium Complex Augments Macrophage Hiv-1 Production And Increases Ccr5 Expression, S. M. Wahl, T. Greenwell-Wild, G. Peng, H. Hale-Donze, T. M. Doherty, D. Mizel, J. M. Orenstein

Faculty Publications

Infection with HIV-1 results in pronounced immune suppression and susceptibility to opportunistic infections (OI). Reciprocally, OI augment HIV-1 replication. As we have shown for Mycobacterium avium complex (MAC) and Pneumocystis carinii, macrophages infected with opportunistic pathogens and within lymphoid tissues containing OI, exhibit striking levels of vital replication. To explore potential underlying mechanisms for increased HIV-1 replication associated with coinfection, blood monocytes were exposed to MAC antigens (MAg) or viable MAC and their levels of tumor necrosis factor α (TNFα) and HIV-1 coreceptors monitored. MAC enhanced TNFα production in vitro, consistent with its expression in coinfected lymph nodes. Using a …

Hematite And Calcite Coatings On Fossil Vertebrates, Huiming Bao, Paul L. Koch, Robert P. Hepple

Faculty Publications

Hematite coatings are common on vertebrate fossils from Paleocene/Eocene paleosol deposits in the Bighorn Basin, Wyoming. In general, hematite coatings are found only on fossils and are limited to soils exhibiting hydromorphic features and moderate maturity. Petrographic and isotopic evidence suggests that hematite and micritic calcite formed at nearly the same time in a pedogenic environment, whereas sparry calcite formed later at greater burial depths. The parent material of paleosols is rich in iron, supplying an ample source of iron for hematite formation. Decomposition of animal tissues around bones may enhance the weathering of iron-bearing minerals in soils surrounding carcasses, …

A Cloned Erwinia Chrysanthemi Hrp (Type Iii Protein Secretion) System Functions In Escherichia Coli To Deliver Pseudomonas Syringae Avr Signals To Plant Cells And To Secrete Avr Proteins In Culture, Jong Hyun Ham, David W. Bauer, Derrick E. Fouts, Alan Collmer

Faculty Publications

The Hrp (type III protein secretion) system is essential for the plant parasitic ability of Pseudomonas syringae and most Gram-negative bacterial plant pathogens. AvrB and AvrPto are two P. syringae proteins that have biological activity when produced via heterologous gene expression inside plant cells or when produced by Hrp+ bacteria. Art-like proteins, presumably injected by the Hrp system on bacterial contact with plant cells, appear to underlie pathogenic interactions, but none has been observed outside of the bacterial cytoplasm, and identifying novel genes encoding them is tedious and uncertain without a phenotype in culture. Here we describe a cloned Hrp …

On Packing Minors Into Connected Matroids, Manoel Lemos, James Oxley

Faculty Publications

Let N be a matroid with k connected components and M be a minor-minimal connected matroid having N as a minor. This note proves that |E(M) - E(N)| is at most 2k - 2 unless N or its dual is free, in which case |E(M) - E(N)| ≤k - 1. Examples are given to show that these bounds are best possible for all choices for N. A consequence of the main result is that a minimally connected matroid of rank r and maximum circuit size c has at most 2r - c + 2 elements. This bound sharpens a result …

The Mentawai Of Siberut Island, Indonesia: A Case Study Of Indigenous Land Use And Conservation Areas, Stacy Crevello

LSU Historical Dissertations and Theses

Indonesia has been blessed with the second most ecologically diverse rain forests in the world. The Indonesian government has recognized the importance of preserving these natural resources as they are in jeopardy of extinction with wide spread logging in direct competition for forest resources. These forests are also home to most of Indonesia's 1.5 million indigenous people who rely on natural resources for survival.

This study analyzes the natural resource use and exploitation of the indigenous Mentawai of Siberut Island, Indonesia. The Mentawaians are atypical as they have historically practiced conservation by following strict taboos and "Adat", the customary law. …

Replication Banding And Sister-Chromatid Exchange Of Chromosomes Of Channel Catfish (Ictalurus Punctatus), Q. Zhang, W. R. Wolters, T. R. Tiersch

Faculty Publications

A replication banding procedure using fluorouracil (FU) and bromodeoxyuridine (BrdU) was developed for use with cultured leukocytes of channel catfish (Ictalurus punctatus). Analyzable banding patterns were produced on chromosomes stained with a fluorochrome plus Giemsa (FPG) method. The consistency of the chromosomal bands was evaluated by computer-assisted image analysis. Banding patterns of representative chromosomes including those bearing nucleolus organizer regions (NOR) were reproducible. A standard RBG-banded karyotype (R bands by BrdU and Giemsa) was established with idiograms of each chromosome. We also developed procedures to study sister- chromatid exchange (SCE) and sister-chromatid differentiation (SCD) in cultured leukocytes, without addition of …

Join In The Dance: Didacticism In Jane Austen's Pride And Prejudice, Lisa Morales

LSU Historical Dissertations and Theses

The importance of didacticism in Jane Austen’s Pride and Prejudice may sometimes be overlooked in an effort to be entertained by the fairy-tale essence of her work. This is unfortunate since Pride and Prejudice offers a rich critique of eighteenth-century English society, as well as heralds the beginning of a new form of novel writing. This new form of novel writing includes a vision of an autonomous heroine who exercises freedom from patriarchal society and the “marriage market.” Austen’s ironic didacticism in Pride and Prejudice highlights hypocrisy and contradiction, and in so doing, mock social expectations. It is through her …

A Descriptive Assessment Model For Writing Programs: A Plan For Louisiana College., Linda Pettus Peevy

LSU Historical Dissertations and Theses

Aware of the proliferation of discussion, activity, and even legislation regarding assessment of educational programs; informed by the Southern Association of Colleges and Schools (SACS) regarding institutional effectiveness; and realizing that assessment efforts are a valid means of revealing programmatic strengths and weaknesses and, therefore, of suggesting where change is needed, the Louisiana College English faculty began in 1991 to study how best to assess the effectiveness of its core requirement in English, a three-semester writing program. The project that forms the basis for this dissertation had its inception in that endeavor. This descriptive study, designed to assess the effects …

The Effects Of An Enriched Environment On The Stereotypic Movement Of Individuals With Profound Mental Retardation., Brandi Braud Smiroldo

LSU Historical Dissertations and Theses

The present study was an attempt to investigate the effects of a specific type of enriched environment on the stereotypic movements of individuals with severe and profound mental retardation. A multisensory room which contained visual, auditory, and tactile stimulation was used. Effects of brief exposure to the multisensory room was compared to effects of exposure to a placebo probe involving attention and access to tangibles and to no treatment controls. Comparisons were made during a 10-minute post-test session immediately following. No significant differences between groups on rate of stereotypic movements at post-test was noted, anecdotal information and review of raw …
