The "Stern Review" And Its Critics: Implications For The Theory And Practice Of Benefit-Cost Analysis, Daniel H. Cole Jan 2008

The "Stern Review" And Its Critics: Implications For The Theory And Practice Of Benefit-Cost Analysis, Daniel H. Cole

Articles by Maurer Faculty

The UK's Treasury's "Stern Review: The Economics of Climate Change" (Oct. 2006) reached dramatically different conclusions and policy recommendations than most earlier economic analyses of climate change. It found that the costs of climate change, as well as the potential net benefits of greenhouse gas reductions, were much higher that previously estimated, and consequently recommended more rapid and extensive cuts in emissions than other economist analysts. The Stern Review estimated that a 1% annual investment of global GDP in mitigation could prevent a 5% (or more) reduction in annual global GDP from climate change harm, forever. A number of prominent …

Navigating The New Politics Of Judicial Appointments, Ryan W. Scott, David R. Stras Jan 2008

Navigating The New Politics Of Judicial Appointments, Ryan W. Scott, David R. Stras

Articles by Maurer Faculty

This Review Essay explores the new politics of judicial appointments by addressing the important question whether Senate-specific reforms to the judicial appointments process are likely to succeed. In his recent book, The Next Justice, Chris Eisgruber proposes a two-part plan to repair the Supreme Court appointments process. Like many other scholars that have written in the area, Eisgruber's reforms focus primarily on the Senate. First, he proposes that the Senate get smart by asking penetrating questions about the judicial philosophy of Supreme Court nominees in an effort to ensure that the future Justices are moderates, rather than extremists. Second, he …

The Synthesis Of Water Soluble N-Acyl Chitosan Derivatives For Characterization As Antibacterial Agents, Lakia Monique Champagne Jan 2008

The Synthesis Of Water Soluble N-Acyl Chitosan Derivatives For Characterization As Antibacterial Agents, Lakia Monique Champagne

LSU Doctoral Dissertations

Currently, natural polysaccharides are being utilized increasingly in the markets because they exhibit biodegradability, biocompatibility, versatility, and are found abundant in nature. The diversity of natural polysaccharides provides the chemist with a broad spectrum of raw materials that can be used in many biological applications. Chitosan is a natural polysaccharide that possesses excellent biological properties. It has been recognized for its antibacterial activity, in that it is destructive towards the bacterium Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). The antibacterial property of chitosan can be enhanced by changing the hydrophobic/hydrophilic nature of the polysaccharide backbone. This research entails …

Grinding The Axe Body Spray: Linking Gamer Experience And Brand Recall In Guitar Hero Iii, Miranda Coy Lemon Jan 2008

Grinding The Axe Body Spray: Linking Gamer Experience And Brand Recall In Guitar Hero Iii, Miranda Coy Lemon

LSU Master's Theses

The growth in popularity of social video games that appeal to a wide variety of audiences offers new opportunities for in-game advertisers to reach beyond the traditional gamer market. The current study aimed to test the effectiveness of in-game advertising placements in the popular video game, Guitar Hero III, based on the Limited Capacity Model of Mediated Motivated Message Processing (LC4MP). The Limited Capacity Model predicts that experienced gamers utilize fewer mental resources when playing video games because the repeated action of playing video games eventually becomes automatic. An experienced gamer would therefore have a greater capacity to remember in-game …

Internet Use And Environmental Justice: An Exploratory Study, Jane Catherine Dailey Jan 2008

Internet Use And Environmental Justice: An Exploratory Study, Jane Catherine Dailey

LSU Doctoral Dissertations

My study examined how inner-city adults perceive and experience the Internet as a civic engagement tool, and if they view the Internet as a tool for environmental advocacy. Research shows a consistent divide between those with Internet access and those without. Individuals living in low-income minority communities are the least likely groups to be Internet connected. Consequently, the Internet could further separate historically marginalized communities from important government and social resources rather than bringing them closer. Qualitative research methods were used to reveal socially-constructed perceptions of the Internet as a civic engagement tool in the inner city. Grounded theory techniques …

Synthesizing Tsca And Reach: Practical Principles For Chemical Regulation Reform, John S. Applegate Jan 2008

Synthesizing Tsca And Reach: Practical Principles For Chemical Regulation Reform, John S. Applegate

Articles by Maurer Faculty

The European Union's newly enacted comprehensive regulation for industrial chemicals, known as REACH, draws heavily on three decades of experience in the United States under the Toxic Substances Control Act. Much of that experience has been negative, inasmuch as TSCA is widely regarded as a disappointment among US environmental laws, and so REACH deliberately reverses many of the legislative choices that Congress made in TSCA. REACH also takes advantage of important new regulatory concepts that were not available to the framers of TSCA thirty years ago. The passage of REACH has sparked renewed interest in reforming TSCA, and the reformers …

Cryopreservation Of Adipose Derived Adult Stem Cells And Multidimensional Cell Sheets, Sreedhar Thirumala Jan 2008

Cryopreservation Of Adipose Derived Adult Stem Cells And Multidimensional Cell Sheets, Sreedhar Thirumala

LSU Doctoral Dissertations

Human adipose tissue provides a uniquely abundant and accessible source of adult stem cells. In response to chemical, hormonal or structural stimuli, these human adipose-derived adult stem (ASCs) cells can differentiate along multiple lineage pathways, including adipocytes, chondrocytes, myocytes, neurons and osteoblasts. Successful cryopreservation of scientifically and commercially important ASCs would revolutionize the tissue engineering and regenerative medicine industry. In this research, we have investigated the water transport phenomenon during freezing of several passages of adipose derived adult stem cells and generated the membrane permeability parameters in the presence and absence of cryoprotective agents. These measured permeability parameters were then …

A Rhetoric Of Existentialism, Zachary Gershberg Jan 2008

A Rhetoric Of Existentialism, Zachary Gershberg

LSU Doctoral Dissertations

Existentialism is often viewed as a morbid philosophy but adapting it to a rhetorical framework reveals a consistent interest in the ontological function of communication. The exchange of discourse and symbols is what ties humans together and existentialism examines the meaning that abounds in life as opposed to attempting to discover the meaning of life. As a rhetorical construct, existentialism provides a critical and unique view of agency and edification as a method of rhetorical practice.

Lattice Boltzmann Modeling For Mass Transport Equations In Porous Media, Borja Servan Camas Jan 2008

Lattice Boltzmann Modeling For Mass Transport Equations In Porous Media, Borja Servan Camas

LSU Doctoral Dissertations

The aim of this dissertation is to extend the lattice Boltzmann method (LBM) to cope with parameter heterogeneity and anisotropy in mass transport equations in porous media, as well as investigating the stability and accuracy. Although the LBM is a well known and effective numerical method to solve fluid flows, LBM has not been extensively applied to mass transport equations in porous medium flow yet, and only a few works can be found on improving LBM to cope with mass transport equations other than the diffusion and advection-diffusion equations. One of the reasons why LBM has not been extensively used …

Synthesis And Surface Characterization Of Silica-Polypeptide Composite Particles, Erick Isael Soto-Cantu Jan 2008

Synthesis And Surface Characterization Of Silica-Polypeptide Composite Particles, Erick Isael Soto-Cantu

LSU Doctoral Dissertations

The synthesis and sequential surface characterization of silica-polypeptide composite particles is described. Nearly monodisperse colloidal silica cores were obtained by the alkaline hydrolysis of tetraethyl orthosilicate (TEOS). The hydrodynamic radius can be easily controlled in the range of ƒî 20-140 nm by the water/TEOS ratio in the starting reaction mixture. The surface of the synthesized silica cores was further passivated/functionalized (P/F) by a mixture of (3-aminopropyl) trimethoxysilane (APS) and methyl-trimethoxysilane (MTMS). The amino groups were quantified using UV-Vis spectrometry after reaction with ninhydrin. The use of zeta potential measurements of the P/F silica particles at low pH is presented as …

Quantification Of Tars And Particulates From A Pilot Scale, Downdraft Biomass Gasifier, Christopher Osita Akudo Jan 2008

Quantification Of Tars And Particulates From A Pilot Scale, Downdraft Biomass Gasifier, Christopher Osita Akudo

LSU Master's Theses

Alternative energy production through biomass gasification produces combustible gases, such as carbon monoxide, hydrogen, and methane. These gases can be used for generation of direct heat, electricity, or liquid fuels through the Fischer Tropsch process. However, a major limitation of the overall process is the purity of the generated synthesis gas. The tars and particulates generated in the gasification process constitute a major impediment to the commercial use of this technology because they may condense on valves, fittings, and therefore, hinder the smooth running of an engine. This research was aimed at developing a gas characterization and testing protocol, and …

Assessing A Hydrothermal Liquefaction Process Using Biomass Feedstocks, Jason S. Midgett Jan 2008

Assessing A Hydrothermal Liquefaction Process Using Biomass Feedstocks, Jason S. Midgett

LSU Master's Theses

The need to reduce the United States dependence on foreign oil has never been greater. In the past decade emphasis has been placed on developing new and/or improved means to procure clean renewable energy. Liquefaction, which was developed for coal conversion over a century ago is one of these areas. Liquefaction used for biomass conversions to bio-oils is grouped under the thermochemical conversion (TCC) area of energy conversion methods along with gasification and pyrolysis. This thesis discusses liquefaction experiments conducted using varieties of Louisiana biomass feedstocks. Dairy manure collected from the Louisiana State University Dairy Farm in Baton Rouge, was …

Foreign News And Public Opinion: Attribute Agenda-Setting Theory Revisited, Asya A. Besova Jan 2008

Foreign News And Public Opinion: Attribute Agenda-Setting Theory Revisited, Asya A. Besova

LSU Master's Theses

This study contributes to the body of research on public opinion and media coverage of foreign news by examining the coverage of nine foreign countries in The New York Times and The Times. Media coverage and the public opinion about foreign nations were strongly correlated. Specifically, negative coverage tends to have more agenda-setting effects than neutral and positive coverage. The findings also suggest that media portray foreign countries in a unidimensional fashion, by limiting the coverage around a few policy issues. Finally, the U.S. and the U.K. media coverage of foreign nations were very similar.

Richard Rorty's Map Of Political Misreading, Shaun Kenan King Jan 2008

Richard Rorty's Map Of Political Misreading, Shaun Kenan King

LSU Master's Theses

For more than a quarter century, Richard Rorty was one of the most controversial writers. Critics of Rorty have often clustered their remarks around distinct themes within Rorty’s body of literature. Is Rorty’s criticism of the correspondence theory of truth valid and what standard of validity could confirm that? Does Rorty’s treatment of pragmatists such as William James and John Dewey accurately reflect their writings? Is Rorty’s brand of liberalism defensible when it assumes no non-circular form of justification can be proffered? These are the questions most often addressed by Rorty’s critics. He responded to their objections for two decades. …

The Gallant Six Hundred: Performing The Light Brigade Into A Heroic Icon, Elizabeth Carrick Cawns Jan 2008

The Gallant Six Hundred: Performing The Light Brigade Into A Heroic Icon, Elizabeth Carrick Cawns

LSU Doctoral Dissertations

History is not so much what actually happened as how we have received and disseminated what happened. This reception and dissemination take place through a variety of media, many of which are not the purview of the traditional historian. It is in the trifles of daily life that we find the patterns of cultural norms – the ethos of the society that is as unnoticed by that society as the air it breathes. Society makes choices that affect the future based on what has been disseminated, rather than on the original event. This is especially true of such military disasters …

Sorption And Desorption Characteristics Of Tylosin In Three Louisiana Soils And Clay Minerals, Zehua Zhou Jan 2008

Sorption And Desorption Characteristics Of Tylosin In Three Louisiana Soils And Clay Minerals, Zehua Zhou

LSU Master's Theses

Tylosin, a macrolide class and widely used antibiotic in animal production, could contaminate environment through manure application to soil and further to river and ground water. Tylosin transport and movement in the environment are largely determined by its sorption and desorption in soils, which are poorly understood so far. Therefore, the purpose of this study was to determine (1) the optimal conditions for tylosin stability, (2) sorption and desorption characteristics of tylosin by poultry litter-impacted three Louisiana soils and (3) sorption and desorption of tylosin by selected clay minerals, the main components of soil which have strong potential application in …

Entertainment Media And "Backstage" Event Framing: How 24 Defines Torture, Skye Chance Cooley

LSU Master's Theses

The purpose of the current study is to examine how the prime time television show 24 frames torture by US government officials almost exclusively in scenarios of high-consequence, high-confidence that are not supported by public opinion polls, provide contextual rationalizations that are unrealistic, show torture methods as a viable means to gain needed information, and show enemy combatants torturing U.S. citizens. Through a quantitative content analysis of torture on the television series 24 and an analysis of focus groups’ reactions to select episodes of 24 portraying torture in such scenarios, the study seeks to investigate the role of entertainment media …

Phonemic Awareness And Sight Word Reading In Toddlers, Alicia Tonya Mcinnis Jan 2008

Phonemic Awareness And Sight Word Reading In Toddlers, Alicia Tonya Mcinnis

LSU Doctoral Dissertations

This study investigated emerging phonemic awareness skills and printed sight word recognition abilities in two-year-old toddlers using plain text and MorphoPhonic Face words on flash cards. MorphoPhonic Face words were used to determine if this learning process is enhanced when words are iconically represented to show the first sound and the word's meaning (purposefully creating idiosyncratic cues) using pictures superimposed into the letters. Sixteen (16) age-matched toddlers were assigned to alternate treatment groups and received exposure to both printed and MorphoPhonic pictured words three times weekly for six weeks. During each session, children were taught 16 sight words (8 in …

Genetic And Mechanistic Analysis Of Heterochromatin Spreading In The Yeast S.Cerevisiae, Nithya Jambunathan Jan 2008

Genetic And Mechanistic Analysis Of Heterochromatin Spreading In The Yeast S.Cerevisiae, Nithya Jambunathan

LSU Doctoral Dissertations

RNA Polymerase III transcribed tRNA genes are implicated in a wide variety of chromosome organizational functions that includes the ability to act as a boundary to heterochromatic silencing. A tRNA gene has been shown to be a major component of the barrier that prevents spreading of silencing from the HMR locus to the downstream GIT1 gene on chromosome III in S.cerevisiae. Our results suggest that additional proteins are involved in maintaining the boundary function of this tRNA gene. Mutations or deletions of the genes coding for these additional proteins have been shown to either weaken the boundary or enhance silencing. …

Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry For The Analysis Of Collected Bioaerosols, Alton John Dugas Jan 2008

Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry For The Analysis Of Collected Bioaerosols, Alton John Dugas

LSU Doctoral Dissertations

The goal of this dissertation was to demonstrate collection, detection and identification of microorganisms from bioaerosols using offline matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of proteins. MALDI-MS intact bacteria techniques were adapted for use with an orthogonal MALDI quadrupole-time-of-flight mass spectrometer. Results indicate the instrument is capable of analyzing intact whole-cells. The first phase was to evaluate three bioaerosol samplers, an Andersen N6 single-stage impactor (AI), a cyclone impactor, and a vacuum filter system. The samplers collected test bioaerosols using a constructed bioaerosol exposure chamber (BEC). The BEC allowed all three samplers to operate in parallel. Each …

Redutive Dehalogenation Of Chlorinated Alkanes By Novel Bacteria At The Petroprocessor Of Louisiana Inc. Superfund Site, Jun Yan

LSU Doctoral Dissertations

A reductively dehalogenating enrichment culture was established using chloroalkane-contaminated groundwater from the PetroProcessors of Louisiana, Inc. (PPI) Superfund site. Two novel, strictly anaerobic bacterial strains, designated as BL-DC-8 and BL-DC-9, were isolated from the enrichment culture. These strains represent the first bacteria known to anaerobically dehalogenate 1,2,3-trichloropropane, the degradation pathway of which was determined. Both strains could be cultured in completely defined basal medium and were also able to dehalogenate a variety of other vicinally chlorinated alkanes including 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane, 1,2-dichloroethane, and 1,2-dichloropropane via dichloroelimination reactions. Chlorinated alkanes containing only a single chlorine substituent (1-chloropropane, 2-chloropropane), chlorinated alkenes (tetrachloroethene, trichloroethene, …

Performing Photographs: Memory, History, And Display, Melanie A. Kitchens Jan 2008

Performing Photographs: Memory, History, And Display, Melanie A. Kitchens

LSU Doctoral Dissertations

In my study, I place concepts and practices of photography and performance in dialogue to enable our understanding of how photographs perform and how performance contains or can contain elements we attribute to photographs. The connection between photography and performance that most intrigues me is how they make memories and when collected or restored in some socially shared way make histories too. My specific aim is to understand how photographs and performance might benefit from each other in how they make and transmit memories and histories. To activate the study, I select and focus on five specific events in which …

The Mise En Scène Of Rossini's Le Siège De Corinthe And The Conventions Of Staging At The Paris Opéra In The 1820s, Tina Huettenrauch Jan 2008

The Mise En Scène Of Rossini's Le Siège De Corinthe And The Conventions Of Staging At The Paris Opéra In The 1820s, Tina Huettenrauch

LSU Master's Theses

Shortly before 1800, the publication of livrets de mise en scène, short manuals including information regarding costumes, set designs, and blocking (i.e., the movement of characters on stage), became increasingly popular in France. While theater scholars (Gösta M. Bergman, Marvin Carlson, Hellmuth Christian Wolff) have recognized the value of these documents for the history of staging (and blocking in particular), musicologists have tended to focus on their impact on visual aspects and realization of drama. Those who have looked at staging (H. Robert Cohen, Rebecca S. Wilberg, M. Elizabeth C. Bartlet) have largely ignored the period prior to 1827, …

Mercury Transport Through A Capped Sediment, Jianrong Liu Jan 2008

Mercury Transport Through A Capped Sediment, Jianrong Liu

LSU Doctoral Dissertations

Laboratory simulation cells were employed to evaluate the effectiveness of a sand cap for containing highly mercury-contaminated lake sediments and the resultant impacts on the mercury fate beneath the cap. Sand cap can delay and reduce the migration of mercury into the overlying water; however, due to the small partition coefficient of mercury between sand and water, a capping material with higher partition coefficient is better for the long-term containment of mercury. In the following study, efforts were made to identify and investigate an active capping material which works effectively at containing and inhibiting the methylation of mercury. Based on …
