Space And Organizations: The Ecology Of Rural Ngos In San Luis Potosi, Mexico, Patricia Marie Campion Jan 2002

Space And Organizations: The Ecology Of Rural Ngos In San Luis Potosi, Mexico, Patricia Marie Campion

LSU Doctoral Dissertations

The field of organizational ecology has been reduced to studies of population dynamics. Ecology, however, is a much broader field, that includes relational, spatial, and temporal dimensions. It allows us to combine existing theories of organizations to study their distribution across space. I combine insights from the new institutionalism, population ecology, and resource-dependence theory, to investigate the factors that influence the location of NGO activities in the state of San Luis Potosí­, Mexico. I conducted interviews and participant observation in 51 rural NGOs. The uneven distribution of NGOs in the state is not the result of their strategy to reach …

Molecular Systematics Of Barbets And Trogons: Pantropical Biogeography African Speciation, And Issues In Phylogenetic Inference, Robert Glen Moyle Jan 2002

Molecular Systematics Of Barbets And Trogons: Pantropical Biogeography African Speciation, And Issues In Phylogenetic Inference, Robert Glen Moyle

LSU Doctoral Dissertations

Modern phylogenetic methods and molecular data can be powerful tools for examining the evolution of organisms. Of particular interest are historical processes that influenced the diversity and distribution of modern taxa. I examined the evolutionary history of two families of birds, the barbets and toucans (Ramphastidae) and the trogons (Trogonidae). Both groups occur in three disjunct tropical regions, a pattern that offers no simple historical explanation. In addition to their distributions, these two families are also similar in that they are relatively ancient groups but have highly conserved and distinctive morphologies. DNA sequence data do not produce concordant phylogenies for …

Study Of A Bacillus Circulans Chitin-Binding Domain By A Green Fluorescent Protein Binding Assay And Detection Of Lysozymes By Improved Zymograms, Markus Hardt Jan 2002

Study Of A Bacillus Circulans Chitin-Binding Domain By A Green Fluorescent Protein Binding Assay And Detection Of Lysozymes By Improved Zymograms, Markus Hardt

LSU Doctoral Dissertations

A fluorescent binding assay was developed to investigate the effects of site-directed mutagenesis on the binding affinity and binding specificity of the chitin-binding domain of chitinase A1 from Bacillus circulans WL-12. The chitin-binding domain (ChBD) was genetically fused to the N-terminus of the green fluorescent protein, GFP. The polyhistidine-tagged hybrid protein was expressed in Escherichia coli under the dose-dependent regulation of the araBAD promoter and purified using metal affinity-, chitin- or ion-exchange chromatography. Residues suggested to be involved in binding from previous three-dimensional studies were mutated and their contributions to binding and substrate specificity were evaluated by depletion assays. Purified …

The "Minor" Author And The Major Editor: A Case Study In Determining The Canon, Christopher Andrew Healy Jan 2002

The "Minor" Author And The Major Editor: A Case Study In Determining The Canon, Christopher Andrew Healy

LSU Doctoral Dissertations

This dissertation explores the relationship between a literary work and its printed edition in the production of reputation--the editor as gatekeeper of the reputation of a “minor” poet. That relationship is demonstrated through a case study on the effects of the nineteenth-century edition of the works of the fifteenth-century poet Thomas Hoccleve and an analysis of the lingering effects of the Foucauldian “editor-function.” The number of surviving manuscripts indicates that Hoccleve’s work was well-regarded during the early fifteenth century, but his reputation fell with that of other non-Chaucerian medieval poets as later critics lost linguistic familiarity with Middle English. The …

Somatic Complaints And Health Care Utilization In Children Exposed To Violence, Kellie Ann Hilker Jan 2002

Somatic Complaints And Health Care Utilization In Children Exposed To Violence, Kellie Ann Hilker

LSU Doctoral Dissertations

In the United States, violence has been referred to as a public health epidemic and violence exposure of our youth is a particularly serious national concern. Numerous negative outcomes are associated with both child victimization and violence exposure including externalizing problems, internalizing symptoms, and poor academic performance. Somatic complaints, which have been associated with internalizing symptoms, have been found as well; however, physical complaints have not been studied in depth. Additionally, health care utilization is an area that is not widely studied in pediatric psychology, but positive associations between posttraumatic stress disorder and increased health care utilization has been found …

Tidal Dynamics In The Bab El Mandab Strait, Ewa Jarosz Jan 2002

Tidal Dynamics In The Bab El Mandab Strait, Ewa Jarosz

LSU Doctoral Dissertations

The Bab el Mandab Strait is where the transition occurs between two noticeably different tidal regimes: the Gulf of Aden, where tidal fluctuations are mixed and have a range in excess of 2 m, and the Red Sea, where the tides are principally semidiurnal and their range is less than 1 m. Within the Strait, observations collected between May of 1995 and July of 1997 indicate that tidal currents are a mixed type and dominant constituents are the K1 and M2. The vertical structure of the tidal currents is complicated, differs between semidiurnal and diurnal constituents, and …

Tailoring Harmonic Radiation To Different Applications Using A Genetic Algorithm, L. Roos, M. B. Gaarde, A. L'Huillier Dec 2001

Tailoring Harmonic Radiation To Different Applications Using A Genetic Algorithm, L. Roos, M. B. Gaarde, A. L'Huillier

Faculty Publications

We use a genetic algorithm to theoretically optimize several properties of extreme ultraviolet (XUV) radiation, generated as high-order harmonics in xenon and argon. We maximize the harmonic pulse energy, minimize the pulse duration or optimize the temporal coherence by varying at the same time two or three parameters that are easily accessible in experiments, related to the characteristics of the laser beam and the nonlinear medium. For the 15th and 29th harmonics in argon, we find up to 109 photons per pulse, and pulse durations as short as 6 fs generated by a 50 fs laser pulse. We can also …

Spatial Patterns Of Morphological Diversity Across The Indo-Pacific: Analyses Using Strombid Gastropods, Kaustuv Roy, Deborah P. Balch, Michael E. Hellberg Dec 2001

Spatial Patterns Of Morphological Diversity Across The Indo-Pacific: Analyses Using Strombid Gastropods, Kaustuv Roy, Deborah P. Balch, Michael E. Hellberg

Faculty Publications

Biological diversity can be measured using various metrics, but existing knowledge of spatial patterns of diversity is largely based on species counts. There is increasing evidence that trends in species richness might not match trends in other biodiversity metrics, such as morphological diversity. Here, we use data from a large group of Indo-Pacific gastropods (family Strombidae) to show that the species richness of a region is a poor predictor of the morphological diversity present there. Areas with only a few species can harbour an impressive array of morphologies and, conversely, morphological diversity in the most species-rich regions is no higher …

Redshifts And Luminosities For 112 Gamma-Ray Bursts, Bradley E. Schaefer, Ming Deng, David L. Band Dec 2001

Redshifts And Luminosities For 112 Gamma-Ray Bursts, Bradley E. Schaefer, Ming Deng, David L. Band

Faculty Publications

Two different luminosity indicators have recently been proposed for gamma-ray bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag between peaks in hard and soft energies (τlag) and the spikiness or variability of the burst's light curve (V). These relations are currently justified and calibrated with only six or seven bursts with known redshifts. We have examined BATSE data for τlag and V for 112 bursts. (1) A strong correlation between τlag and V exists, and it is exactly as predicted from the two proposed relations. This is proof that both luminosity indicators …

Magnetic Field Effects On Neutron Diffraction In The Antiferromagnetic Phase Of Upt3, Juana Moreno, J. A. Sauls Dec 2001

Magnetic Field Effects On Neutron Diffraction In The Antiferromagnetic Phase Of Upt3, Juana Moreno, J. A. Sauls

Faculty Publications

We discuss possible magnetic structures in UPt3 based on our analysis of elastic neutron-scattering experiments in high magnetic fields at temperatures T < TN. The existing experimental data are compatible with a true antiferromagnetic order displaying a single-q antiferromagnetic structure with three independent domains. For modest in-plane spin-orbit interactions, the Zeeman coupling between the antiferromagnetic order parameter and the magnetic field induces a rotation of the magnetic moments, but not an adjustment of the propagation vector of the magnetic order. A triple-q magnetic structure is also consistent with neutron experiments, but in general leads to a nonuniform magnetization in the crystal. New experiments involving higher fields and polarized neutrons could decide between these structures. © 2000 The American Physical Society.

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas Dec 2001

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas

Faculty Publications

To facilitate detection of glycoprotein K (gK) specified by herpes simplex virus, a 12-amino-acid epitope tag was inserted within gK domain III. Recombinant virus gKprotC-DIII, expressing the tagged gK, was isolated. This virus formed wild-type plaques and replicated as efficiently as the wild-type KOS virus in Vero cells. Anti-protein C MAb detected high-mannose and Golgi complex-dependent glycosylated gK within cells as well as on purified virions. The gK-null virus ΔgK (gK-/-) entered Vero cells substantially more slowly than the wild-type KOS (gK+/+), while ΔgK virus grown in complementing VK302 cells (gK-/+) entered with entry kinetics similar to those of the …

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer Dec 2001

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer

Faculty Publications

An outbreak of Fusobacterium necrophorum-induced septicemia occurred in a group of 40 captive wild-caught pronghorns (Antilocapra americana). Primary pododermatitis or necrotic stomatitis progressed to produce fatal septicemia with metastatic lesions in the forestomachs, lung, liver, and cecum in 38 of the animals. Two remaining animals were euthanatized because of chronic pododermatitis. Housing the animals in a pasture previously used by bovids and heavy rains with persistence of ground water pools in the pasture were contributing factors in the pathogenesis of this outbreak.

Probing D-Wave Pairing Correlations In The Pseudogap Regime Of The Cuprate Superconductors Via Low-Energy States Near Impurities, Daniel E. Sheehy, A. Adagideli, Paul M. Goldbart, Ali Yazdani Dec 2001

Probing D-Wave Pairing Correlations In The Pseudogap Regime Of The Cuprate Superconductors Via Low-Energy States Near Impurities, Daniel E. Sheehy, A. Adagideli, Paul M. Goldbart, Ali Yazdani

Faculty Publications

The issue of probing the pseudogap regime of the cuprate superconductors, specifically with regard to the existence and nature of superconducting pairing correlations of d-wave symmetry, is explored theoretically. It is shown that if the d-wave correlations believed to describe the superconducting state persist into the pseudogap regime, but with pair-potential phase fluctuations that destroy their long-range nature, then the low-energy quasiparticle states observed near extended impurities in the truly superconducting state should also persist as resonances in the pseudogap regime. The scattering of quasiparticles by these phase-fluctuations broadens what was (in the superconducting state) a sharp peak in the …

A search for ν̄μ→ν̄e oscillations was conducted by the Liquid Scintillator Neutrino Detector at the Los Alamos Neutron Science Center using ν̄μ from μ+ decay at rest. A total excess of 87.9±22.4±6.0 events consistent with ν̄ep→e+n scattering was observed above the expected background. This excess corresponds to an oscillation probability of (0.264±0.067±0.045)%, which is consistent with an earlier analysis. In conjunction with other known limits on neutrino oscillations, the LSND data suggest that neutrino oscillations occur in the 0.2-10 eV2/c4 Δm2 range, indicating a neutrino mass greater than 0.4 eV/c2. ©2001 The American Physical Society.

We present measurements of the semi-inclusive cross sections for νμ- and ν̄μ-nucleon deep inelastic scattering interactions with two oppositely charged muons in the final state. These events dominantly arise from the production of a charm quark during the scattering process. The measurement was obtained from the analysis of 5102 νμ-induced and 1458 ν̄μ-induced events collected with the NuTeV detector exposed to a sign-selected beam at the Fermilab Tevatron. We also extract a cross-section measurement from a reanalysis of 5030 νμ-induced and 1060 ν̄μ-induced events collected from the exposure of the same detector to a quad-triplet beam by the Chicago Columbia …

Swst 1: An O-Rich Planetary Nebula Around A C-Rich Central Star, Orsola De Marco, P. A. Crowther, M. J. Barlow, Geoffrey C. Clayton, A. De Koter Dec 2001

Swst 1: An O-Rich Planetary Nebula Around A C-Rich Central Star, Orsola De Marco, P. A. Crowther, M. J. Barlow, Geoffrey C. Clayton, A. De Koter

Faculty Publications

The hydrogen-deficient [WCL] type central star HD 167362 and its planetary nebula (PN) SwSt 1 are investigated. The central star has a carbon-rich emission-line spectrum, and yet the nebula exhibits a 10-μm emission feature from warm silicate dust, perhaps indicating a recent origin for the carbon-rich stellar spectrum. Its stellar and nebular properties might therefore provide further understanding as to the origin of the [WCL] central star class. The central star optical and UV spectra are modelled with state-of-the art non-LTE codes for expanding atmospheres, from which the stellar parameters are determined. Using the Sobolev approximation code ISA-Wind, we find …
