Designing Group Examinations To Decrease Social Loafing And Increase Learning, Lee Revere Ph.D., Max Elden Ph.D., Robert A. Bartsch Ph.D.
Designing Group Examinations To Decrease Social Loafing And Increase Learning, Lee Revere Ph.D., Max Elden Ph.D., Robert A. Bartsch Ph.D.
International Journal for the Scholarship of Teaching & Learning
This study examines a method to decrease social loafing in a group examination. Students who met in teams during the semester took an exam in groups. Rules for the exam, based on the Jeopardy game show, facilitated both group and individual accountability. Feedback from students indicated that compared to a class that did not have group exams, students taking the group exam had less social loafing and had higher perceived levels of learning. Furthermore, among students taking the group exams, higher group participation was related to higher perceived performance and more positive attitudes about the exam. We developed a model …
Book Review: Integrative Learning: Mapping The Terrain By Mary Taylor Huber And Pat Hutchings (Association Of American Colleges And Universities, 2004), Renita Schmidt
International Journal for the Scholarship of Teaching & Learning
Excerpt: In my own past public school teaching experiences, interdisciplinary learning, thematic instruction, and inquiry approaches all provided ways for students to mesh ideas across disciplines and sign systems with a complex gelling of ideas and knowledge building. Taking these ideas another step further, Integrative Learning: Mapping the Terrain offers detailed suggestions for how integrated knowledge building could look in the college or university setting. Mary Taylor Huber and Pat Hutchings are scholars at The Carnegie Foundation for the Advancement of Teaching. In this work, they offer a plausible and viable argument for college and university faculties who believe …

Phylogenetics And New Approaches To Vaccine Development For West Nile, Arun Venkatesh Iyer
Phylogenetics And New Approaches To Vaccine Development For West Nile, Arun Venkatesh Iyer
LSU Doctoral Dissertations
West Nile virus (WNV) was first isolated in 1937 from a febrile Ugandan woman. WNV now has a worldwide distribution from Australia and India in the east to Europe and the United States in the west. The first human cases of WNV in the United States were detected in New York in 1999. The North American isolates were also found to be highly neuroinvasive and neurovirulent and in many cases leading to mortality or permanent CNS sequelae among humans. WNV was first isolated in Louisiana in 2001. The genome of this virus named LSU-AR01was sequenced and a detailed genetic analysis …

Evaluation Of Aflatoxin-Related Products From Ozonated Corn, Alfredo Domingo Prudente, Jr.
Evaluation Of Aflatoxin-Related Products From Ozonated Corn, Alfredo Domingo Prudente, Jr.
LSU Doctoral Dissertations
This study assessed the efficacy of the ozonation process in degrading aflatoxin in corn, and investigated the chemical reaction between aflatoxin and gaseous ozone. Ozonation (12-13 wt%) totally degraded aflatoxin B1 in a model system. Conversion of aflatoxin into polar compounds was observed during ozonolysis of 100 µg aflatoxin B1 in an aqueous environment and in solid form. Seven intermediate reaction products were separated by two-dimensional thin layer chromatography. HPLC analysis of ozonated AFB1 revealed the presence of six major peaks. MALDI-MS analysis detected compounds that have higher molecular weights than AFB1. The dichloromethane fraction contained compounds with molecular ion …
Solution Conformations And Structural Thermodynamics Of Type I Dna Polymerases From Escherichia Coli And Thermus Aquaticus, Allison Joubert Richard
Solution Conformations And Structural Thermodynamics Of Type I Dna Polymerases From Escherichia Coli And Thermus Aquaticus, Allison Joubert Richard
LSU Doctoral Dissertations
The global conformations of DNA polymerase I from Thermus aquaticus (Taq/Klentaq) and E. coli (Pol I/Klenow) both in isolation and in complex with DNA have been examined in solution using hydrodynamic (analytical ultracentrifugation) and small/wide angle X-ray scattering techniques and then compared to their known crystal structures to assess the similarities and differences in the overall structure of these enzymes and enzyme complexes within a solution environment. These studies address the orientation of the 5’ nuclease domain with respect the polymerase domain (elongated or compact) for the full-length polymerases, and the binding mode (“polymerization” versus “editing”) of the DNA substrate …
Exercise And Peripheral Vascular Function In Health And Disease, Arturo Arce
Exercise And Peripheral Vascular Function In Health And Disease, Arturo Arce
LSU Doctoral Dissertations
“Chronic disease will never reach its clinical horizon to compromise health if it is attacked at its origin” [1]. Knowledge that one’s risk for cardiovascular events is related to the severity of endothelial dysfunction, and evidence that exercise training can improve endothelial function, has prompted speculation that measures of vascular function may serve as a “barometer” for cardiovascular health. This dissertation consists of three experiments intended to study vascular function and the manner in which it may influence or may be influenced by physical function. Project one examined the influence of high and low volume circuit weight training on forearm …
Changes In Body Image And Body Weight And Shape Goals Associated With Weight Loss And Maintenance In Overweight/Obese Adults Diagnosed With Type 2 Diabetes Mellitus, Amy Rzeznikiewicz Bachand
Changes In Body Image And Body Weight And Shape Goals Associated With Weight Loss And Maintenance In Overweight/Obese Adults Diagnosed With Type 2 Diabetes Mellitus, Amy Rzeznikiewicz Bachand
LSU Doctoral Dissertations
The primary aim of this study was to test for changes in body image in males and females in a randomized controlled trial of weight loss for older overweight/obese adults who have been diagnosed with type 2 diabetes (Look AHEAD: Action for Health in Diabetes). A computerized morphing assessment program (The Body Morph Assessment; BMA 2.0) was used to assess estimates of perceived current body size (CBS), ideal body size (IBS), acceptable body size (ABS), body dissatisfaction based on the discrepancy between participants’ perceived CBS and IBS (CBS-IBS) and ABS (CBS-ABS), as well as participants’ weight loss goals in terms …

Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao
Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao
LSU Doctoral Dissertations
Rice straw fiber can be considered as important potential reinforcing filler for thermoplastic composite because of its lignocellulosic characteristics. It is thus of practical significance to understand and predict the thermal decomposition process of rice straw fibers. A method proposed by Málek, Šesták, and co-workers was used to investigate and model thermal decomposition process of common natural fibers with detailed analysis on rice straw system. Assuming a global model occurring within the entire degradation of natural fibers with consideration of fiber as one pseudo-component, model can be used to describe both isothermal and non-isothermal degradation process of most selected fibers …
Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry For The Analysis Of Collected Bioaerosols, Alton John Dugas
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, …

The Apostle, Mr. Justice Jackson, And The Pathological Perspective Of The Free Exercise Clause, Ronald J. Krotoszynski Jr.
Articles
The generally accepted interpretation of Justice William O. Douglas's majority opinion in United States v. Ballard, 322 U.S. 78 (1944), casts the case as a ringing defense of religious freedom in the United States; a trial court may not charge a jury with inquiring into the factual truth of a defendant's religious beliefs incident to a prosecution for criminal fraud. This interpretation of Ballard is, at least arguably, unduly generous. By permitting juries to inquire into a religious leader's subjective good faith belief in the tenets of the faith, the Ballard majority provides an insufficient shield against prosecutions based on …

Illusory Consent: When An Incapacitated Patient Agrees To Treatment, Fredrick E. Vars
Articles
Medical treatment requires informed consent which in turn requires decision making capacity When a patient with questionable capacity does not resist treatment these requirements are often neglected treatment is administered with no assessment of capacity and no consideration of alternative decision making A variety of ethical and legal forces contribute to this neglect The practical effect is that patients are treated when if they had capacity they would refuse treatment This subverts the dominant interest in health care decision making patient autonomy After surveying current law and practice this article addresses the following issues 1 when to test patients for …
Dynamic Shear Bands In Metals Under High Strain Rates, Amin Hisham Almasri
Dynamic Shear Bands In Metals Under High Strain Rates, Amin Hisham Almasri
LSU Doctoral Dissertations
Adiabatic shear bands have been observed for a long time to occur under different conditions in many applications. Analysis of these localizations highly depends on the selection of the constitutive model. Hence, two constitutive models that take temperature and strain rate effect into account are proposed. The first model is a physically based model that depends on basic physical quantities, such as dislocation densities, Burgers vector, and activation energy. The second model is a simple empirical power model with a softening term. The empirical constitutive law is seen to be more successful in capturing the mechanical behavior of steel alloy …
Synthesis And Surface Characterization Of Silica-Polypeptide Composite Particles, Erick Isael Soto-Cantu
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 …

How To Remember Thee?: Problems Of Memorialization In English Writing, 1558-1625, Sean Flory
How To Remember Thee?: Problems Of Memorialization In English Writing, 1558-1625, Sean Flory
LSU Doctoral Dissertations
This dissertation focuses on the use of funeral commemoration in religious and political controversies in early modern England. By examining the rhetoric used in funeral sermons and elegies, I show that commemorative writers use figural interpretation of the Bible to legitimize praise by linking the deceased to characters from scripture. Figural interpretation places the dead into a framework of ecclesiastical history and creates Protestant saints used as exempla in political and religious debates. This dissertation examines funeral sermons, elegies, and other commemorative poems written between 1558 and 1625. Chapter one discusses the development of figural interpretation in Elizabethan funeral sermons. …
Characterization And Comparison Of Cell Frequency, Growth, And Multipotential Differentiation Of Adult Mesenchymal Stromal Cells Derived From Equine Bone Marrow And Adipose Tissue, Martin Andreas Vidal
Characterization And Comparison Of Cell Frequency, Growth, And Multipotential Differentiation Of Adult Mesenchymal Stromal Cells Derived From Equine Bone Marrow And Adipose Tissue, Martin Andreas Vidal
LSU Doctoral Dissertations
Equine bone marrow-derived mesenchymal stromal cells (MSCs) and adipose tissue-derived stromal cells (ASCs) were compared for frequency within their respective tissues, cell doubling characteristics and differentiation multipotential in culture based on histochemical staining and compositional analysis. Equine MSCs and ASCs from young adult horses were harvested and isolated from sternal bone marrow and supragluteal subcutaneous adipose tissue, respectively, and grown up to passage 10 (P10) to determine cell doubling characteristics. Limit dilution assays were performed on primary and passaged (P2, P4) MSCs and ASCs to determine the frequency of colony forming units with a fibroblastic phenotype (CFU-F), and the frequency …

Incorporation Of Cα,Α-Disubstituted Amino Acids Into Model Peptide Systems: Conformational Analysis And Possible Applications As Therapeutic Agents, Marcus A. Etienne
LSU Doctoral Dissertations
A diverse set of human diseases is associated with the misfolding of proteins into insoluble fibrillar structures that have predominantly β-sheet secondary structure. Thus it is imperative to elucidate the structural elements that contribute to β-sheet formation and stability. Peptides that autonomously form β-sheets are ideal models to study principles of protein folding and design. Gellman and coworkers first introduced an automonously folded β-hairpin (H-Arg-Tyr-Val-Glu-Val-Yyy-Xxx-Orn-Lys-Ile-Leu-Gln-NH2) that remained monomeric up to ~1 mM. Circular dichroism (CD) and nuclear magnetic resonance (NMR) analyses revealed that incorporation of non-stereogenic Aib-Xxx dipeptidyl sequences into i+1 and i+2 positions of a model peptide nucleates a …
Chemical Analysis Of Polymer Blends Via Synchrotron X-Ray Tomography, Heath Alan Barnett
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 …
