Instead Of Enda, A Course Correction For Title Vii, Jennifer S. Hendricks

Publications

In September 2008, the D.C. federal court issued a landmark decision holding that discrimination against a transgender person was sex discrimination under Title VII. This decision throws into sharp relief the ongoing debates among supporters of the Employment Non-Discrimination Act about whether the compromise on including protection for gender identity claims. Consideration of ENDA in some form will likely be early on the agenda of the next Congress, especially under a Democratic administration likely to support the bill. This essay proposes an alternative to ENDA that would embrace the theoretical connections between sex, gender, and sexual orientation, with important practical …

Développement De Marqueurs Et Validation D’Outils De Diagnostic Pour Le Dépistage De L’Hypersensibilité Induite Par Le Béryllium, Michel Fournier, Jacques Bernier, Pauline Brousseau, Daniel Cyr, Guy Viel, Sébastien Sauvé

Rapports de recherche scientifique

Le béryllium est connu pour sa grande toxicité. Il provoque, suite à l’inhalation de poussières ou de vapeurs des pneumopathies sévères (bérylliose) et des atteintes chroniques dite maladie chronique du béryllium (MCB). En moyenne, 1à 20% des travailleurs exposés deviennent sensibilisés, desquels 1 à 10 % développent la MCB. Il existe un test de laboratoire couramment utilisé pour déceler la sensibilisation d’un travailleur au béryllium; il s’agit du test de prolifération des lymphocytes en présence de béryllium le "Beryllium Lymphocyte Proliferation Test" (BeLPT). Bien que ce test permette de détecter la sensibilisation, il offre peu de valeur prédictive quant aux …

Framing Wrongful Convictions, Susan S. Bandes

Utah Law Review

Concern over wrongful convictions has led to an “innocence movement” that has managed to bridge ideological divides, rouse people to action, and achieve unprecedented success in reforming the operation of the death penalty. In this short Article, written as part of the symposium “Beyond Biology: Wrongful Convictions in a Post-DNA World,” I consider the fraught terms of the debate about the content of the category of wrongful convictions. Delineating the category raises two controversial issues: who should be considered wrongly convicted, and how to characterize the governmental misconduct that leads to these miscarriages of justice. This Article considers whether it …

Providing A Safe Harbor For Those Who Play By The Rules: The Case For A Strong Regulatory Compliance Defense, Richard C. Ausness

Utah Law Review

On September 25, 2003, a fire broke out at the National Health Care (NHC) nursing home facility in Nashville, Tennessee, causing sixteen deaths and a number of injuries from smoke inhalation.1 Thirty-two victims subsequently filed suit against the nursing home, alleging that NHC was negligent for failing to install sprinklers in its facility.2 This claim was made notwithstanding the fact that applicable federal, state, and local safety regulations did not require the installation of sprinklers in this particular type of building, and notwithstanding that the NHC facility had been inspected by state fire inspectors just months before the fire and …

Disability And “Late Style” In Music, Joseph N. Straus

Publications and Research

“Late style” is a longstanding aesthetic category in all the arts. Late-style music is presumed to have certain internal qualities (such as fragmentation, intimacy, nostalgia, or concision) and to be associated with certain external factors (such as the age of the composer, his or her proximity to and foreknowledge of death, lateness within a historical period, or a sense of authorial belatedness with respect to significant predecessors). Upon closer inspection, it appears that many of these external factors are unreliably correlated with a musical style that might be described as late. Late style is often better correlated with the bodily …

Chemical Analysis Of Polymer Blends Via Synchrotron X-Ray Tomography, Heath Alan Barnett

LSU Doctoral Dissertations

Material properties of industrial polymer blends are of great importance. X-ray tomography has been used to obtain spatial chemical information about various polymer blends. The spatial images are acquired with synchrotron X-ray tomography because of its rapidity, good spatial resolution, large field-of-view, and elemental sensitivity. The spatial absorption data acquired from X-ray tomography experiments is converted to spatial chemical information via a linear least squares fit of multi-spectral X-ray absorption data. A fiberglass-reinforced polymer blend with a new-generation flame retardant is studied with multi-energy synchrotron X-ray tomography to assess the blend homogeneity. Relative to other composite materials, this sample is …

Dactyls Reveal Evolutionary Patterns In Decapod Crustaceans, Jeffrey Guy Agnew

LSU Doctoral Dissertations

Because of their high preservation potential and uses in foraging and defense, decapod crustacean dactyls (movable fingers of claws) are potentially excellent test subjects for an ongoing debate concerning the relative importance of top-down (predators) and bottom-up (prey) controls on morphologic diversification and evolution. The utility of dactyls for inferring evolutionary patterns were evaluated using living and subfossil xanthoid crabs sampled from the southeast U.S. Atlantic and Gulf of Mexico coasts, and were used to: (1) distinguish the roles of selection and constraint on dactyl morphology through allometric and shape comparisons in the context of the crab’s phylogenetic relationships and …

Fabrication Of Micro Bumps For Micro Scale Thermal Management, Ajay Ashok Kardak

LSU Master's Theses

Cryopreservation is storage of biological systems at ultra low temperatures for a prolonged duration; such that they can be thawed and restored to the same living state. It is important to understand the behavior of cells when they are subjected to subzero temperatures. Research in this area has shown the occurrence of two main biophysical events; cellular dehydration and intracellular ice formation. Current techniques for characterizing the dehydration in cells as part of a tissue are not adequate for studying intracellular ice formation in tissues. An integrated device consisting of an array of thermal sensors (microthermocouples) and actuators (microthermoelectric coolers) …

Three Papers On The Behavior Modeling Of The Shrimp Fishermen In The Gulf Of Mexico, Tao Ran

LSU Doctoral Dissertations

The overall goal of this research is to empirically analyze shrimp fishermen behavior to help improve the management of the Gulf of Mexico shrimp fleet. Given that optimal management requires consideration of more than the net benefits derived from shrimp harvesting, this research also seeks to provide an empirical framework that would allow future investigators to measure benefits lost through bycatch-related management actions. This paper expands on previous fishing behavior literature by focusing on two of the most important short-run decisions confronting Gulf of Mexico shrimp fishermen (where to fish and how long to fish). A better understanding of these …

Sex-Specific Feeding Rates And Provisioning Of Fruit To Nestling Bell's Vireo, Greg H. Farley

The Prairie Naturalist

Provisioning of fruit to nestlings and possible sex-specific differences in feeding rate have not been reported for Bell's vireo (Vireo bellii; Brown 1993). While studying nesting ecology of Bell's vireo on Konza Prairie Biological Station, Geary and Riley counties, Kansas, I quantified feeding rate by sex and food type delivered to nestlings. Sex was determined by capturing adults with mist-nets and inspecting for a cloacal protuberance, as well as conducting behavioral observations of uniquely-marked individuals. Males sing regularly while moving around territories, as well as during incubation (Nolan 1960). I assigned "female" to the individual in these socially …

Zoological Label As Literary Form, Victor Fet

Biological Sciences Faculty Research

Nabokov’s work is seen through the unique concept of zoological labels and their language. A label, written by a young naturalist, is a concentrated source of information, detail, and “naming the unnamed”; it reflects three Aristotelian unities (place, time, action).

Telemetric Assessment Of Stereotypical Motor Movements In Children With Autism Spectrum Disorder, Matthew S. Goodwin

Open Access Dissertations

Stereotypical motor movements are one of the most common and least understood behaviors occurring in individuals with Autism Spectrum Disorder (ASD). When severe, engagement in these behaviors can lead to social stigmatization and complicate social interaction. Moreover, if a stereotypical motor movement becomes a dominant behavior in an individual's repertoire, it can interfere with the performance of established skills and acquisition of new skills, and may lead to self-injurious behavior. Stereotypical motor movements are complex and thought to serve a multiplicity of functions. However, problems with traditional methods for measuring stereotypical motor movements have made it difficult to determine when …

Applications Of Linear And Cyclic Peptides As Enzyme Inhibitors And Molecular Transporters, Guofeng Ye

Open Access Dissertations

The diversity of amino acids in peptides allows the design of different linear or cyclized compounds. Peptides can be designed to act as inhibitors, probes, or molecular transporters of other molecules. The objective of this dissertation research was to exploit the diversity of peptide structures and focused on developing linear and cyclic peptides as c-Src inhibitors and using the information derived from c-Src crystal structure to design novel peptide-based molecular transporters. A series of peptide analogues of Ac-CIYKYY were designed and synthesized to improve the inhibitory potency against active Src Linear peptide Ac-CIYKF(4-NO 2)Y (IC50 = 0.53 μM) and a …

Analysis Of Resonating Microcantilevers Operating In A Viscous Liquid Environment, Cyril Vančura, Isabelle Dufour, Stephen M. Heinrich, Fabien Josse, Andreas Hierlemann

Civil and Environmental Engineering Faculty Research and Publications

The characteristics of resonant cantilevers in viscous liquids are analyzed. Various rectangular cantilevers geometries are studied in pure water, glycerol and ethanol solutions of different concentrations, and the results are described in terms of the added displaced liquid mass and the liquid damping force for both, the resonance frequency and the quality factor (Q-factor). Experimental results using a set of magnetically actuated resonant cantilevers vibrating in the out-of-plane (“weak-axis bending”) mode are presented and compared to theoretical calculations. The importance of the study is in the use of resonant cantilevers as biochemical sensors in liquid environments.

Dosimetry Intercomparison Using A 35-Kev X-Ray Synchrotron Beam, Scott Oves

LSU Master's Theses

Significance: Photon activated Auger electron therapy utilizes a keV-ranged, monoenergetic x-ray beam, and radiobiological and animal experiments studying this therapy require accurate dosimetry techniques. However, there exist few dosimetry protocols for low-energy x-ray beams. This research intended to use the CAMD synchrotron as a source of monochromatic, 35-keV x-rays and test dosimetry techniques of film and ion chamber. The hypothesis of my research was that depth-dose measured in a PMMA phantom using an air-equivalent ionization chamber and radiochromic film dosimeters in a PMMA phantom irradiated by a 35-keV, monochromatic x-ray beam will agree to within 5% of each other and …

This project investigated the accuracy of ExacTrac and 4DCT imaging localizing an implanted coil at various phases of respiration. Radiochromic film measured delivered dose patterns for selected gating intervals over a variety of respiratory patterns. In order to establish accurate dosimetry, this project implemented and tested an EBT radiochromic film dosimetry system. Film testing showed that the performance of a medical grade Vidar Dosimetry Pro radiographic film scanner and an Epson V700 Photo …

Concentration Of Phosphorylated Proteins Using Modified Pmma Microanalytical Devices, Jowell Guerra Bolivar

LSU Doctoral Dissertations

This work describes the application of PMMA-based microanalytical devices for the affinity-type preconcentration of posttranslational modified proteins (PTMs). The choice of poly(methyl methacrylate), PMMA, is based on its biocompatibility, its functional methyl ester group for potential modification, and its extensive applications to create biological microelectromechanical systems (BioMEMS). Developing methodologies for preconcentration of PTMs is important for cancer diagnosis due to PTMs’ influence in the regulatory mechanism underlying the early stage of apoptosis or regulated cell death. Towards this goal, nitroavidin which can reversibly binds to biotin (and biotinylated proteins), was prepared using reported procedure and was characterized using several techniques …

Novel Oncolytic Herpesviruses For Breast Cancer Treatment, Anna Israyelyan

LSU Doctoral Dissertations

Oncolytic herpes simplex virus type-1 (HSV-1) has shown great potential as an effective agent for cancer therapy ¨C oncolytic virotherapy. To enhance oncolytic capabilities of previously reported agents, new oncolytic and fusogenic HSV-1 OncSyn and OncdSyn viruses were constructed based on wild type HSV-1 (F) strain. To provide for safety and tumor selectivity, the viruses carried a large deletion including one of the two ¦Ã134.5 genes. The ¦Ã134.5 gene, a major neurovirulence factor, was replaced by a gene cassette constitutively expressing the red fluorescent protein. Homologous recombination was utilized to transfer the fusogenic gBsyn3 mutation to the viral genome to …

Detection Of Rare Tp53 And Kristen-Ras Mutational Frequencies In Human Sperm, Derek N. Cole

LSU Doctoral Dissertations

There is mounting evidence of impacts of single base substitutions in both somatic and inherited genetic diseases. However, the occurrence of single base mutations in the germline and gametes has previously only been by conjecture and assumption. There is a need for understanding the risk of offspring inheriting small intragenic mutations, the frequencies at which these mutations are present in germ cells, and the impact that these inherited mutations may have son the predisposition to somatic disease during one’s lifetime. The present study attempts to establish baselines of mutational frequencies in two well characterized genes in human tissues, and demonstrate …

Distributions And Associations Of Single Nucleotide Polymorphisms In The Leptin Gene Of Bos Taurus And Bos Indicus Cattle, Douglas Henry Fischer, Jr

LSU Master's Theses

In recent years, the use of genetic markers has become more and more prevalent in beef breeding programs. This research focused on four previously identified single nucleotide polymorphisms in a leptin gene on chromosome 4 of beef cows. The SNP were E2FB, T945M, UA1, and UA2. Beef cows used in this research were maintained at the Louisiana State University AgCenter Central Research Station. Cows consisted of purebred Bos tauras and Bos indicus cattle as well as crossbreds. The objectives were to estimate genotypic and allelic frequencies for each SNP and to determine the influence of cow breed type, cow age, …

Durable And Reusable Antimicrobial Textiles, Leila Elizabeth Bonin

LSU Master's Theses

Antimicrobial textiles are a large research focus in the textile industry. There is an apparent need for creating reusable and durable antimicrobial textiles. Most of the textiles with antimicrobial properties effective against Staphylococcus aureus are disposable. To address the issue, two types of biopolymer solutions were created in a USDA lab. Both solutions displayed antimicrobial properties. A medium weight, plain weave cotton sheeting was used as the test fabric. Samples of the sheeting were cut, treated, and tested to determine their efficacy as antimicrobial textiles. The tests performed included tensile deformation, bending, shearing, compression, surface friction, surface roughness, and treatment …
