Testing Democracy: The Case Of The 17th Amendment And Constituency Representation, Rhonda Wrzenski Jan 2005

Testing Democracy: The Case Of The 17th Amendment And Constituency Representation, Rhonda Wrzenski

LSU Master's Theses

This paper examines a unique aspect of Congressional history centering on the passage of the 17th amendment in 1913, which shifted the power of U.S. Senate elections from the state legislature to state electorates. This paper examines how the passage of the amendment affected the relationship between characteristics of the state electorate and the roll call behavior of U.S. Senators. Due to the historical nature of the time period, I use Presidential election results by state, party control of the governorship and upper and lower chambers of the state legislature, as well as a number of demographic variables, to estimate …

Computational Model For Elasto-Plastic And Damage Analysis Of Plates And Shells, Pawel Benedykt Woelke Jan 2005

Computational Model For Elasto-Plastic And Damage Analysis Of Plates And Shells, Pawel Benedykt Woelke

LSU Doctoral Dissertations

Shells and plates are very important for various engineering applications. Analysis and design of these structures is therefore continuously of interest to the scientific and engineering community. Accurate and conservative assessments of the maximum load carried by the structure, as well as the equilibrium path in both elastic and inelastic range are of paramount importance. Elastic behaviour of shells has been very closely investigated, mostly by means of the finite element method. Inelastic analysis on the other hand, especially accounting for damage effects, has received much less attention from the researchers. A computational model for finite element, elasto-plastic and damage …

Complexifying The Poetic: Toward A Poiesis Of Curriculum, Donna Lynn Trueit Jan 2005

Complexifying The Poetic: Toward A Poiesis Of Curriculum, Donna Lynn Trueit

LSU Doctoral Dissertations

Inspired by philosopher Richard Rorty’s assertion that we need poetic imagination to move beyond modernity, this pragmatist inquiry seeks to understand the poetic, not as it is rationally defined, but rather as a historically situated discursive practice. In western cultures modernist discursive practices are characterized by rationalist reasoning. Traced to Aristotelian re- interpretations of mimesis (this is that), which structure modernist forms of representation, mimesis operates on a principle of equivalency between the specific and the universal, based on Euclidean, geometric reasoning. Likewise, mimesis underlies poetic representation as an imaginative expression of an objective reality, ideally, a form that moves …

Evaluation Of A Novel Method Of Predicting Estrogen Activity Of A Group Of Structurally Diverse Compounds, Daniel Consoer Jan 2005

Evaluation Of A Novel Method Of Predicting Estrogen Activity Of A Group Of Structurally Diverse Compounds, Daniel Consoer

LSU Master's Theses

The number of environmental chemicals found to have some level of endocrine activity has led to concern about the possible effects these compounds could have on human health and the health of other species, populations, and possibly whole ecosystems. The United States Environmental Protection Agency has been charged with testing a large number of these compounds, called endocrine-disrupting chemicals or hormonally active agents for hormonal activity. Limited testing resources have led to a call for alternate methods of screening, possibly for use in prioritizing this list to assist in efficient allocation of resources for further testing. This study describes a …

Long-Term Changes And Variability In Northern Hemisphere Circumpolar Vortex, Kalyn Mackenzie Wrona Jan 2005

Long-Term Changes And Variability In Northern Hemisphere Circumpolar Vortex, Kalyn Mackenzie Wrona

LSU Master's Theses

Variability in the hemispheric-scale atmospheric circulation can be directly linked to variations in surface environmental features, such as temperature, precipitation, and pollutant transport. One indicator of the behavior of the hemispheric-scale circulation is the circumpolar vortex (CPV). This research utilizes a geographic information system (GIS) approach to determine the variability in the northern hemisphere (NH) CPV. Specifically, the area, shape, and centroid of the December, January, February, April, July, and October NHCPV are analyzed for 1959 – 2001 because these features may provide insight about relationships between hemispheric-scale circulation and global temperature change throughout the year. A “circularity ratio” is …

Virtual Property, Joshua Fairfield Jan 2005

Virtual Property, Joshua Fairfield

Articles by Maurer Faculty

This article explores three new concepts in property law. First, the article defines an emerging property form - virtual property - that is not intellectual property, but that more efficiently governs rivalrous, persistent, and interconnected online resources. Second, the article demonstrates that the threat to high-value uses of internet resources is not the traditional tragedy of the commons that results in overuse. Rather, the naturally layered nature of the internet leads to overlapping rights of exclusion that cause underuse of internet resources: a tragedy of the anticommons. And finally, the article shows that the common law of property can act …

Photobiological And Thermal Effects Of Uva Light On Cell Culture, Julianne Forman Jan 2005

Photobiological And Thermal Effects Of Uva Light On Cell Culture, Julianne Forman

LSU Master's Theses

The objective of this study is to characterize the photobiological and thermal effects of UVA light on cell cultures. While near-ultraviolet light has been widely used to photoactivate fluorophores and caged compounds in cells, little is known of the long-term biological effects of this light. UVA (320-400nm) photoactivating light has been used for studying fast kinetic processes and is now being employed in higher doses to target longer duration phenomena (e.g. gene expression and silencing). Photoexposure experiments using 365nm light will examine how longer duration and increased UV doses affect photoactivation cell studies. Apoptotic and cellular injury assays have been …

Rights Of Humans, Rights Of States: The Academic Legacy Of St. George Tucker In Nineteenth-Century Virginia, Chad Vanderford Jan 2005

Rights Of Humans, Rights Of States: The Academic Legacy Of St. George Tucker In Nineteenth-Century Virginia, Chad Vanderford

LSU Doctoral Dissertations

College professors in the nineteenth-century South lavished a great deal of attention on the issues of slavery and constitutionalism, and they paid careful attention to the connections between these issues and the idea of natural rights. In this dissertation I offer an analysis of the lives and writings of three generations of college professors in nineteenth-century Virginia, focusing especially on St. George Tucker and his descendants. As a contemporary of Thomas Jefferson and as a delegate to the Annapolis convention, Tucker can rightly be considered as one of the founding fathers. But he is best known for inaugurating the academic …

Integrating Horticulture Biology And Coastal Environmental Issues Into The Middle School Science Curriculum, Kathryn Lauren Karsh Jan 2005

Integrating Horticulture Biology And Coastal Environmental Issues Into The Middle School Science Curriculum, Kathryn Lauren Karsh

LSU Master's Theses

Louisiana is losing nearly 34 square miles of coastal land each year. Scientists predict by 2050 one-third of Louisiana’s coast land will disappear (LaCoast, 2004). Many restoration projects have begun to counteract the severe land loss. Scientists use restoration methods such as vegetative plantings, sedimentary and freshwater diversions, and hydrologic projects to prevent land loss. Coastal Roots, a school-based nursery stewardship project for upper elementary to high school students coordinated by Louisiana Sea Grant College Program and LSU AgCenter, helps students understand the land loss crisis and gives them a constructive way to help restore the damaged coastal habitats by …

Biologically Inspired Learning System, Patrick Mcdowell Jan 2005

Biologically Inspired Learning System, Patrick Mcdowell

LSU Doctoral Dissertations

Learning Systems used on robots require either a-priori knowledge in the form of models, rules of thumb or databases or require that robot to physically execute multitudes of trial solutions. The first requirement limits the robot’s ability to operate in unstructured changing environments, and the second limits the robot’s service life and resources. In this research a generalized approach to learning was developed through a series of algorithms that can be used for construction of behaviors that are able to cope with unstructured environments through adaptation of both internal parameters and system structure as a result of a goal based …

Separation And In Situ Catalytic Testing Of A Dirhodium Tetraphosphine Catalyst, Bobby Lloyd Barker Jan 2005

Separation And In Situ Catalytic Testing Of A Dirhodium Tetraphosphine Catalyst, Bobby Lloyd Barker

LSU Doctoral Dissertations

Attempts to study the asymmetric hydroformylation abilities of [rac-Rh2(nbd)2(et,ph-P4)](BF4)2 were made through the separation of the enantiomers of et,ph-P4 using a chiral HPLC column. Efforts were also made to optimize the NiCl2 separation chemistry for the methyl analogue of et,ph-P4 for use in asymmetric hydroformylation. A study of hydroformylation of olefins using [rac-Rh2(nbd)2(et,ph-P4)](BF4)2 in ionic liquids was also performed, leading directly to the important (and unexpected) effect of increased hydrogen pressure on [rac-Rh2(nbd)2(et,ph-P4)](BF4)2 in the acetone/water system to …

Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere Jan 2005

Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere

LSU Doctoral Dissertations

This dissertation addresses Samuel Beckett's bilingualism in an effort to understand how the author's use of language affected his writing style and depiction of gender. Beckett began writing in English, switched to French for the composition of new works for ten years, and then returned unexpectedly to English. His first English works are characterized by stylistic virtuosity, erudition, and misogyny. With Beckett's adoption of French his style became simple, spare, and cerebral. Plot structure based on a journey in early works was abandoned in favor of static situations and dialogue. Women were either ignored or viewed negatively. In 1956, Beckett …

Multicultural Lawyering: Teaching Psychology To Develop Cultural Self-Awareness, Carwina Weng Jan 2005

Multicultural Lawyering: Teaching Psychology To Develop Cultural Self-Awareness, Carwina Weng

Articles by Maurer Faculty

Much of the current literature in multicultural lawyering focuses on learning substantive information about clients who are culturally different from the lawyer, such as how the client's culture perceives eye contact or reacts to science-based world views. This article notes that such a focus sidesteps the human reality that every person reacts to people who are different from him- or herself unconsciously in ways that may be culturally insensitive and discriminatory and that this human reaction occurs despite awareness of the general values, attitudes, and beliefs of the client's culture. It therefore suggests that multicultural lawyering training should begin with …

"Let Me Play A While": Storytelling Characters And Voices In The Works Of Mark Twain, William Faulkner, And Lee Smith, Kenneth Mark Broyles Jan 2005

"Let Me Play A While": Storytelling Characters And Voices In The Works Of Mark Twain, William Faulkner, And Lee Smith, Kenneth Mark Broyles

LSU Doctoral Dissertations

This dissertation focuses on the difference between narrators and characters in fiction who tell stories. It also argues that traditional orality persists in American culture and is a significant influence in the fiction of Mark Twain, William Faulkner and Lee Smith. In their work, they try to overcome what some perceive as a structural discrimination inherent in the novel and imbue their characters' speaking voices with authority that is determined by something other than their position in the structural hierarchy. All three authors attempt to give their characters speaking voices which are not necessarily inferior to the narrative or authorial …

The release of the 1000th complete microbial genome will occur in the next two to three years. In anticipation of this milestone, the Fellowship for Interpretation of Genomes (FIG) launched the Project to Annotate 1000 Genomes. The project is built around the principle that the key to improved accuracy in high through put annotation technology is to have experts annotate single subsystems over the complete collection of genomes, rather than having an annotation expert attempt to annotate all of the genes in a single genome. Using the subsystems approach, all of the genes implementing the subsystem are analyzed by …

Molecular Recognition And Its Underlying Mechanisms In Molecularly Imprinted Polymers, Ryan Simon Jan 2005

Molecular Recognition And Its Underlying Mechanisms In Molecularly Imprinted Polymers, Ryan Simon

LSU Doctoral Dissertations

Molecular recognition in molecularly imprinting polymers (MIPs) is governed by two mechanisms: pre-organization of functional groups and shape specificity of the binding site. While pre-organization of functional groups has been studied extensively, shape specificity of the binding site has not been rigorously explored. The goal of this research is to determine the influence of shape specificity on molecular recognition in MIPs (Chapter 2). Once shape selectivity was proven to play a vital role in molecular recognition, it was important to determine if pre-organization of functional groups or shape specificity was the dominating factor in determining molecular recognition in the binding …
