Chiral Analyses Using Molecualr Micelles And Multiple Regression Modeling In Chromatographic And Spectroscopic Methods, Alicia Williams Snearl

LSU Doctoral Dissertations

Multiple regression modeling techniques allow for rapid and accurate prediction of migration times and resolution values for micellar electrokinetic chromatography (MEKC) as well as the development of quick screening methods using steady-state fluorescence spectroscopy. All studies reported in this dissertation include optimization of calibration models and predictions of dependent variables by the use of validation samples. The root-mean-square percent relative error (RMS%RE) is used as a figure of merit for characterizing the performance of the calibration models. MEKC separations of achiral and chiral analytes were performed using an achiral molecular micelle, poly(sodium N-undecylenic sulfate), and chiral molecular micelles, poly(sodium N-undecanoyl-L-leucylvalinate) …

Free Women Of Color And Slaveholding In New Orleans, 1810-1830, Anne Ulentin

LSU Master's Theses

Many free women of color lived in antebellum New Orleans. Free women of color tried hard to improve their lives, and engaged in a wide range of economic activities, including slaveholding. Numerous records show that free women of color owned slaves. It is hard to determine why free women of color engaged in such business. Free women of color’s relations with their slaves is controversial as it is difficult to assess why free black women would own slaves, but also buy, sell, and mortgage slaves. Free women of color’s status was exceptional due to specific patterns of manumission in Spanish …

Dna Multiplex Hybridization On Microarrays And Thermodynamic Stability In Solution: A Direct Comparison, Daniel J. Fish, M. Todd Horne, Greg P. Brewood, Jim P. Goodarzi, Saba Alemayehu, Ashwini Bhandiwad, Robert P. Searles, Albert S. Benight

Chemistry Faculty Publications and Presentations

Hybridization intensities of 30 distinct short duplex DNAs measured on spotted microarrays, were directly compared with thermodynamic stabilities measured in solution. DNA sequences were designed to promote formation of perfect match, or hybrid duplexes containing tandem mismatches. Thermodynamic parameters DeltaH degrees , DeltaS degrees and DeltaG degrees of melting transitions in solution were evaluated directly using differential scanning calorimetry. Quantitative comparison with results from 63 multiplex microarray hybridization experiments provided a linear relationship for perfect match and most mismatch duplexes. Examination of outliers suggests that both duplex length and relative position of tandem mismatches could be important factors contributing to …

America's Decision To Drop The Atomic Bomb On Japan, Joseph H. Paulin

LSU Master's Theses

During the time President Truman authorized the use of the atomic bomb against Japan, the United States was preparing to invade the Japanese homeland. The brutality and the suicidal defenses of the Japanese military had shown American planners that there was plenty of fight left in a supposedly defeated enemy. Senior military and civilian leaders presented Truman with several options to force the surrender of Japan. The options included the tightening of the naval blockade and aerial bombardment of Japan, invasion, a negotiated peace settlement, and the atomic bomb became an option, once bomb became operational. Truman received recommendations, advice …

Technology Adoption Of Indian Garment Manufacturing Firms, Venu Varukolu

LSU Master's Theses

The purpose of this study is to investigate the status and the effect of organizational factors on the level of technology adoption within the context of the Indian garment industry. Specifically, this study focuses on the effect of firm size, export orientation, top management’s commitment, cost of capital, technical skills, and competitive advantage. An online survey using a structured questionnaire was prepared through an online research service. A multiple regression analysis (MRA) was used to test the hypotheses. The results revealed that firm size positively influences and export orientation negatively influences the technology adoption level of a firm. The effect …

Role Of Heparanase And Heparanase-Degraded Heparan Sulfate In Brain-Metastatic Melanoma, Madhuchhanda Roy

LSU Doctoral Dissertations

Cancer metastasis is a frequent manifestation of malignant melanoma progression. Successful invasion into distant organs by tumor cells must include attachment to microvessel endothelial cells, and degradation of extracellular matrix. Heparan sulfate proteoglycans are ubiquitous macromolecules associated with cell surface and extracellular matrix of a wide range of cells and tissues. Heparanase is an extracellular matrix degradative enzyme which degrades the heparan sulfate chains of heparan sulfate proteoglycans. To investigate effects of changes in heparanase gene expression in metastatic melanoma cells, we constructed adenoviral vectors containing the full-length human heparanase cDNA in both sense (Ad-S/hep) and anti-sense orientations (Ad-AS/hep). We …

A Comparison Of Social Skills Profiles In Intellectually Disabled Adults With And Without Asd, Jonathan Wilkins

LSU Master's Theses

Although there has been a recent increase in research directed toward autism spectrum disorders (ASD), the study of intellectually disabled adults with ASD has gone relatively neglected as efforts have focused largely on young children. Current diagnostic and assessment procedures were created for and validated on this latter group. Many intellectually disabled adults with ASD have not been diagnosed due to the novelty of such instruments and the overlap between symptoms of ASD and severe intellectual disability (ID). A new assessment instrument, the Autism Spectrum Disorders-Diagnostic Scale for Intellectually Disabled Adults (ASD-DA) has been shown to make this fine distinction. …

Alphabetic And Phonemic Awareness In Toddlers, Pamela A. Terrell

LSU Doctoral Dissertations

The ability of 20-24 month-old toddlers to recognize graphemes and phonemes was investigated by reading a Phonic Faces (PF) alphabet picture book. Phonic Faces iconically picture a letter in the mouth of a character producing the sound (the curve of the P looks like the top lip popping the /p/ sound). The book was composed of nine letters and was read individually to experimental subjects three times weekly for six weeks. The control group received no treatment, but engaged in individual play activities for comparable time. Following six-weeks the groups alternated so the former control group now received the alphabet …

An explanatory case study was conducted in a private high school currently subscribing to the Emergenetics® STEPTM program. Emergenetics® STEPTM Profile results of students enrolled in the school’s six Multimedia Productions courses were analyzed as the basis for learning group construction. Key individual thinking preferences (Analytical, Structural, Social, Conceptual) identified by the STEPTM Profile was the main variable of analysis. One learning group from each of the six classes (n …

Transcendental Eigenvalue Problems Associated With Vibration, Buckling And Control, Jayaram Subramanian

LSU Master's Theses

The static and dynamic analysis of structures requires us to obtain solutions of their espective governing differential equations subject to appropriate boundary conditions. The dynamic analysis of non-uniform continuous structures is of primary interest, as most traditional methods take the help of discrete models to analyze them. Well established discrete model methods lead to an algebraic eigenvalue problem, the characteristic equation associated with which is a polynomial. The spectral characteristics of a continuous system nevertheless are represented by transcendental functions and cannot be approximated by polynomials efficiently. Hence finite dimensional discrete models are not capable of predicting the response of …

The New Commerce Clause Doctrine In Game Theoretical Perspective, Maxwell L. Stearns

Vanderbilt Law Review

The Roberts Court emerges at a critical juncture in the development of Commerce Clause doctrine. While the Commerce Clause doctrine implicates federalism and separation of powers, concerns rooted in the earliest part of our constitutional history, the arrival of a new Court presents an ideal opportunity to critically assess existing doctrines and to develop new analytical paradigms. An analysis of Commerce Clause doctrine reveals that while the Rehnquist Court successfully imposed substantive limits on the scope of this important source of congressional power for the first time in sixty years, that Court was far less successful in developing a coherent …

Predictive Data Compression Using Adaptive Arithmetic Coding, Claudio Jose Iombo

LSU Master's Theses

The commonly used data compression techniques do not necessarily provide maximal compression and neither do they define the most efficient framework for transmission of data. In this thesis we investigate variants of the standard compression algorithms that use the strategy of partitioning of the data to be compressed. Doing so not only increases the compression ratio in many instances, it also reduces the maximum data block size for transmission. The partitioning of the data is made using a Markov model to predict if doing so would result in increased compression ratio. Experiments have been performed on text files comparing the …

Flow Field And Heat Transfer Analyses Of Mechanical Seals, Zhaogao Luan

LSU Doctoral Dissertations

Mechanical seals are widely used in rotating equipment such as pumps, turbines and agitators to prevent leakage. One crucial factor for keeping seals reliable is the thermal behavior of the seal rings. The existing literature on thermal effects in seals primarily concentrates on the conduction of heat into the rings. Yet, a more complete analysis requires understanding of the flow field around the rings. In this dissertation, both the laminar and turbulent flows within the seal chamber are studied and their effects on the heat transfer in the seal rings are evaluated. Based on extensive sets of numerical simulations, heat …

Department Of Pathology, Thomas Jefferson University, Identification Of Conserved Gene Expression Features Between Murine Mammary Carcinoma Models And Human Breast Tumors., Jason I Herschkowitz, Karl Simin, Victor J Weigman, Igor Mikaelian, Jerry Usary, Zhiyuan Hu, Karen E Rasmussen, Laundette P Jones, Shahin Assefnia, Subhashini Chandrasekharan, Michael G Backlund, Yuzhi Yin, Andrey I Khramtsov, Roy Bastein, John Quackenbush, Robert I Glazer, Powel H Brown, Jeffrey E Green, Levy Kopelovich, Priscilla A Furth, Juan P Palazzo, Olufunmilayo I Olopade, Philip S Bernard, Gary A Churchill, Terry Van Dyke, Charles M Perou

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Although numerous mouse models of breast carcinomas have been developed, we do not know the extent to which any faithfully represent clinically significant human phenotypes. To address this need, we characterized mammary tumor gene expression profiles from 13 different murine models using DNA microarrays and compared the resulting data to those from human breast tumors. RESULTS: Unsupervised hierarchical clustering analysis showed that six models (TgWAP-Myc, TgMMTV-Neu, TgMMTV-PyMT, TgWAP-Int3, TgWAP-Tag, and TgC3(1)-Tag) yielded tumors with distinctive and homogeneous expression patterns within each strain. However, in each of four other models (TgWAP-T121, TgMMTV-Wnt1, Brca1Co/Co;TgMMTV-Cre;p53+/- and DMBA-induced), tumors with a variety of …

Rethinking The Application Of Ada Precedent To Feha Disability Discrimination Cases, Gabriel N. White

UC Law Journal

This Note addresses the practice in California state courts of applying federal precedent from cases under the ADA to resolve questions of statutory interpretation in state cases under FEHA. The author argues that this practice risks error because of the significant differences between California state disability law and federal disability law.

The discussion takes as its starting point two recent California appellate cases. In the first, Gelfo v. Lockheed Martin Corp., the California Court of Appeal addressed a matter of first impression under state law, but which had split the federal circuits. The author questions the Gelfo court's method of …

Of Elephants And Embryos: A Proposed Framework For Legal Personhood, Jessica Berg

UC Law Journal

What is a person? What responsibilities or obligations do we have to entities that we recognize as persons under the law? These are not simply theoretical questions. Questions of legal personhood have already faced courts and legislatures and are likely to become more relevant as technology advances.

Legal personhood has largely been ignored outside of the corporate context. Yet there is a pressing need to answer the question of what constitutes a person. This Article's focus is on legal status and the ways in which the law should recognize rights and interests of certain entities.

There are two bases for …

Identifying Effective And Ineffective Schools For Accountability Purposes: A Comparison Of Four Generic Types Of Accountability Models, Fen Yu

LSU Doctoral Dissertations

The stakes associated with student performance have been raised to new highs under the No Child Left Behind Act (NCLB, 2001). Many people are concerned with the adequacy and appropriateness of the statistical models used in identifying low-performing schools for educational accountability. The purpose of this study was to compare four generic types of accountability models (i.e., status models, improvement models, growth models, and value-added models) and see if they reach consistent/inconsistent conclusions regarding the effectiveness of the same set of schools. Further, the four models were also compared in terms of “fairness”. A fair model is defined as one …

The Microeconomics Of International Price Dispersion, Ozlem Inanc

LSU Doctoral Dissertations

This dissertation investigates the reasons behind international price dispersion. The first essay, “International Price Dispersion and the Direction of Trade”, discusses the importance of trade cost as a determinant of international price dispersion. The importance of trade costs in segmenting product markets can not be captured by considering aggregate prices or in the absence of information on the direction of trade. The first essay, addresses this problem by utilizing product-specific prices along with cross-sectional productivity measures and bilateral trade flows that allow us to identify the probable source of any one product. The empirical approach used in this work is …

School Readiness And Preschoolers' Attachment Representations: Possible Connections, Katherine A. Darbonne

LSU Master's Theses

The current study examined the possible relationship between preschooler's school readiness and their attachment representations. More specifically, the study examined preschooler's performances on standardized tests and their perceptions of close relationships. The possible connection between school readiness and attachment representations was through children's experiences of stress during standardized testing situations (Fleege, Charlesworth, Burts, & Hart, 1992) and children's stress invoking the use of their internal working models (Bowlby, 1969/1982). The children were administered the Brigance CIBS-R (Glascoe, 1999), a standardized test that was most often used in the local schools to assess school readiness. The children were also videotaped while …

News Narratives And Television News Editing, Keren Esther Henderson

LSU Master's Theses

This study seeks to understand how and why television news editors impose meanings onto news packages through montage editing. Through a qualitative content analysis and in-depth interviews, this study will advance the notably few past narrative editing studies by investigating the norms and routines of television news editors. While other researchers recognize the significance of studying montage editing in television news, this is the first study to clarify the relationship between montage techniques and the creation of television news narratives.

LSU Doctoral Dissertations

This project is concerned with a new medical geography approach to investigating Chagas disease in Los Tuxtlas, Mexico which focuses on the intersection of disease risk and place. More specifically this work will describe the domestic cycle of Chagas disease and the cultural factors that perpetuate its transmission in six communities in the Los Tuxtlas region, Municipio San Andres, Veracruz State, Mexico. Using several collection techniques, such as interviews and house type surveys, as well as identifying and collecting the vector Triatoma dimidiata (including testing them for the parasite Trypanosoma cruzi), this dissertation describes the characteristics of the Chagas landscape …

What Is Natural Resources Law?, Robert L. Fischman

Articles by Maurer Faculty

A recent flurry of new natural resources law casebooks, coming a quarter-century since the publication of the last significant new teaching materials, is an occasion to revisit the boundaries that define the field. The similarities among the casebooks are stronger than their differences, and represent a consensus about what composes natural resources law. The published teaching materials as well as an informal poll of natural resources law professors show a substantial overlap between natural resources and environmental law course coverage. Administrative implementation of statutes dominates both subjects. Both courses typically cover environmental impact analysis and endangered species protection. The new …

Savings Clauses And Trends In Natural Resources Federalism, Robert L. Fischman, Angela King

Articles by Maurer Faculty

This article considers recent trends in federalism, with particular attention to natural resource law's statutory savings clauses. It begins with a case study of elk management in Jackson Hole, Wyoming. The elk controversy shows how a statutory savings clause can provide a state with traction to advance its interests, and demonstrates how the political winds of change can shift the balance of state-federal relations. The article then focuses on the common statutory savings clauses and their roles in circumscribing federal agency authority and establishing a basis for cooperation between federal and state governments. We analyze the interpretive approaches the judiciary …

A Novel Template Stage With Superior Alignment Capability For Nanoimprint And Step And Flash Lithography, Yunmi Jeon

LSU Master's Theses

The high-resolution capabilities of imprinting and step and flash lithography make these techniques strong contenders for the next generation lithography. Unfortunately, alignment remains an area of concern for nanoimprint because it must be completed before the template is moved into contact with the wafer. The large forces on the template during the process, even for step and flash, place additional demands on the stiffness as well as the reproducibility of the template stage. In this thesis, a prototype flexure stage has been developed to meet these demands. A compressive load, slightly below the Euler's limit, is used to produce relatively …

A Geographical Investigation Of Chagas' Disease Risk In The Community Of La Brea, Guatemala, Gerardo J. Boquin

LSU Master's Theses

This thesis will display how the use of a GIS is an important tool in understanding geographic patterns of Chagas' disease vector risk in a rural community in Guatemala. This is an important topic of investigation as Chagas' disease is the leading cause of heart failure in rural Latin America, and yet study has been limited due to a prioritization of national resources to urban diseases. Obviously this can have a severe impact on rural areas, especially if they already lack adequate health care provision. As a response to this deficiency, a collaboration between the Laboratory of Entomology and Applied …
