Is The Ecomap A Valid And Reliable Social Work Tool To Measure Social Support?, Alexandra R. Calix Jan 2004

Is The Ecomap A Valid And Reliable Social Work Tool To Measure Social Support?, Alexandra R. Calix

LSU Master's Theses

The ecomap, developed in 1975, is a tool used in social work practice to measure social support (Hartman, 1995). Although the ecomap is widely utilized, due in part to its ease of administration, it has not been validated in the literature as a reliable and valid tool in the measure of social support. This study aims to quantify the ecomap, explore its psychometric soundness, and begin the process of validation using two empirically validated social support measurement tools, the Multidimensional Scale of Perceived Social Support (MSPSS) (Zimet, Dahlem, Zimet, & Farley, 1988) and the Young Adult Social Support Inventory (YA-SSI) …

Middlegate Japanese Gardens: Preservation, Private Property And Public Memory, Margaret Anne Legett

LSU Master's Theses

The purpose of thesis is to provide a preliminary history of Middlegate Japanese Gardens and to make public their significance as an example of the landscape architecture that was typical during the Country Place Era, and their significance within the community of Pass Christian and the City of New Orleans. As it now stands the story of Middlegate Japanese Gardens is not known in its own neighborhood. Between 1923 and 1929 New Orleans residents Rudolf Hecht and Lynne Watkins Hecht developed Middlegate Japanese Gardens at their summer home in Pass Christian, Mississippi. The Hecht’s built Middlegate Japanese gardens to perpetuate …


Pulse, Janet L.U. Rudawsky Jan 2004

Pulse, Janet L.U. Rudawsky

LSU Master's Theses

This video is an abstract audiovisual narrative. It relies heavily on its lush compositions to seduce the viewer. “Pulse” depicts humanity not as the strong rational rulers of the earth but instead as a tormented figure that struggles to find security in an uncertain world. The three characters, Blood, Lava, and Electricity, represent the human animal, the natural world, and civilization respectively. Blood struggles against both Lava and Electricity in their rivalry for control. The plot shows humanity developing a relationship with civilization, all the while being harassed by unpredictable nature. Civilization at first is a path to security. As …


Mems Accelerometer: Proof Of Concept For Geotechnical Engineering Testing, Keith Nicholas Hoffman Jan 2004

Mems Accelerometer: Proof Of Concept For Geotechnical Engineering Testing, Keith Nicholas Hoffman

LSU Master's Theses

Geotechnical engineering materials are inherently variable, which leads to many simplifications when trying to model their behavior. The materials must always be characterized prior to any design work so that the engineer knows which direction he must progress to have a reliable design. Although subsurface characterization techniques and geotechnical design steadily improve, they are by no means infallible. The combination of geotechnical subsurface characterization along with geophysical techniques for improved design and construction monitoring has begun to surface as a viable alternative to the standard techniques in geotechnical engineering. This is important because there is a lack of Quality Control/Quality …


Effect Of Cotton Aphids, Aphis Gossypii (Glover), On Cotton Plant Development And Yield Components, Robert Hankins Jones Jan 2004

Effect Of Cotton Aphids, Aphis Gossypii (Glover), On Cotton Plant Development And Yield Components, Robert Hankins Jones

LSU Master's Theses

The effect of cotton aphids, Aphis gossypii (Glover), on cotton plant development and yield was studied during 2000 and 2001. Tests were conducted at the Macon Ridge Station (Winnsboro, Louisiana) in 2000 and 2001, and at the Northeast Research Station (St. Joseph, Louisiana) in 2001. Tests were performed in irrigated and non-irrigated regimes using individual plant comparisons, micro-plots, and whole plots. In both years and at both locations, cotton aphid densities induced chlorosis, and a downward cupping of leaves during the infestation period. The insecticides, pymetrozine and thiamethoxam, were applied to control natural infestations of cotton aphids. Although pymetrozine and …


Design Exploration: Totem As Alternative For Efficient And Socially Responsive Burial, Mark Evan Bazzell Jan 2004

Design Exploration: Totem As Alternative For Efficient And Socially Responsive Burial, Mark Evan Bazzell

LSU Master's Theses

American cities are facing unprecedented development pressures. Urban populations in particular are increasing and diversifying, land as a resource is becoming more valuable, and designers/developers are challenged to creatively maximize space for all land uses. As urban populations grow, space for burial of the dead may become limited thereby prompting communities to consider alternatives to traditional burial. The increase in numbers of cremation already points to this trend. In addition to the spatial limitation issues there also exist issues of social and cultural limitation. Ethnic diversity is rapidly increasing and within each group one finds different traditions and needs regarding …


Identification Of Soybean Cultivars Tolerance To Waterlogging Through Analyses Of Leaf Nitrogen Concentration, Curt Jude Riche Jan 2004

Identification Of Soybean Cultivars Tolerance To Waterlogging Through Analyses Of Leaf Nitrogen Concentration, Curt Jude Riche

LSU Master's Theses

Irrigation to soybean can cause unintended water to pond on the soil surface for more than a desired amount of time. Most soybean acreage in Louisiana is planted on poorly drained clay soils and waterlogging of soybean can cause substantial yield reductions. Although cultural practices are available for ameliorating the adverse effects of waterlogging, little is known about genotypic tolerance, therefore our objectives were to determine if percent leaf nitrogen concentration could be used as a criterion for screening for cultivar tolerance to waterlogging and to identify waterlogging tolerance among 48 commercially available soybean cultivars. Forty-eight soybean cultivars were planted …


Ultra Deep Su-8 Manufacturing And Characterization For Mems Applications, Charles Joseph Becnel Jan 2004

Ultra Deep Su-8 Manufacturing And Characterization For Mems Applications, Charles Joseph Becnel

LSU Master's Theses

The Micro Systems Engineering Team (mSET) at Louisiana State University (LSU) utilizes microfabrication for a number of heat and mass transfer devices. These include cross flow heat exchangers, mechanical seals with integrated micro heat exchangers, catalytic converters, and micro reactors. In all of these applications, micro honeycomb arrays provide increased surface area per unit volume which significantly enhances heat and mass transfer. In the past, it was only possible to fabricate SU-8 structures approximately 1.5 mm tall. Furthermore, qualitatively, it is much more difficult to fabricate close packed feature arrays than sparse arrays. For many of the previously mentioned applications, …

The Realization Of L2 Speech Events: A Quantitative Study Of Korean Speakers Of L2 English With Respect To Formality And Proficiency, Nevin Liddy Jan 2004

The Realization Of L2 Speech Events: A Quantitative Study Of Korean Speakers Of L2 English With Respect To Formality And Proficiency, Nevin Liddy

LSU Master's Theses

Guided written conversations were studied from English speakers at four different proficiency levels. They were analyzed according to their speech act realization, speech event realization, and conversation management (as reflected by three levels of speech acts: primary, secondary, and complementary). All four proficiency levels were found to be capable in the formulation of speech acts and events, demonstrating access to certain discourse principles at all levels. Language proficiency was found to effect the way in which a speech event was realized to a greater degree than the level of formality was found to effect the way in which the speech …


The Catalyst To Harm Standard: Punishing Speech That Facilitates Harm, J. Colin Trisler Jan 2004

The Catalyst To Harm Standard: Punishing Speech That Facilitates Harm, J. Colin Trisler

LSU Master's Theses

The Catalyst to Harm Standard is a specific standard that sets forth step-by-step criteria for the courts to follow so that they can factually determine if the speech in question falls into the category of protected or unprotected speech. This Standard labels certain speech as “bad” not because of its ideological or social content, but because it is speech that is linked to a definitive social harm that the legislature has the constitutional authority to prevent or punish. This Standard uses three criteria to determine the liability of speech that has allegedly caused harm. In order to meet these requirements, …


Lattice Boltzmann Simulation Of Flow Around Bluff-Bodies, Kevin Tubbs Jan 2004

Lattice Boltzmann Simulation Of Flow Around Bluff-Bodies, Kevin Tubbs

LSU Master's Theses

In this work, results from a 2-D Lattice Boltzmann (LB) solver are presented simulating flow past rectangular square cylinders at low Reynolds numbers (< 250). The LBGK equation is a hyperbolic equation that approximates the Navier Stokes equations in the nearly incompressible limit. It is a system of 9 one dimensional partial differential Hamiltonian-Jacobian equations, consisting of an advection and diffusive portion. The LB method is an alternative computational fluid dynamics (CFD) method used to numerically predict incompressible viscous flow. The current LB method uses a statistical mechanics formulation to solve the Boltzmann equation. The LB model captures the nonlinear Navier Stokes advection terms using linear streaming operators. In this thesis, the LB model is classified as an explicit, Lagrangian, finite-hyperbolicity and weakly compressible approximation of the Navier Stokes equations. The momentum flux tensor is captured locally as opposed to a pressure field eliminating the need to solve the Poisson equation. This allows the fluid structure interactions (FSI) behavior to be calculated elegantly at the interface through the mesoscopic momentum transfer between the fluid and structure. At this level, the forces are simultaneously calculated. The LB equations are discretized both in time and phase space using a standard D2Q9 lattice model. Validation tests for flow around single square cylinders at different aspect ratio at low Reynolds numbers are presented. Good agreement with other investigators is achieved. Flow past multiple bluff bodies (representing building in a city) is also presented. The vortex shedding simulations presented provide preliminary indications in terms of St that the LB method can be used to simulate high Re flow.


Attribution Processes In Mother-Adolescent Conflict, Ann Elisabeth Wingate Jan 2004

Attribution Processes In Mother-Adolescent Conflict, Ann Elisabeth Wingate

LSU Master's Theses

The present study aimed to determine whether negative mother and adolescent attributions about one another are associated with increased conflict levels in a heterogeneous sample, examine the possible differential predictive power of certain negative attribution types for different groups within the sample, determine whether level of negative attribution, SES, or daily stress level are significant predictors of conflict, and examine the potential mediating role of negative attributions in the relationship between SES and conflict level, as well as the relationship between and daily stress and conflict level. One hundred forty-five mother-adolescent dyads from various racial and SES backgrounds of a …


An Economic Evaluation Of Using Management Zones In Cotton Production, Jose Antonio Cabrera-Davila Jan 2004

An Economic Evaluation Of Using Management Zones In Cotton Production, Jose Antonio Cabrera-Davila

LSU Master's Theses

This thesis examines the use of Precision Agriculture technologies to define Management Zones within a multicrop production system. It further evaluates the economic feasibility of implementing spatially variable insecticide applications against conventional blanket treatments with respect to insect pest management in cotton production. The use of geographical information systems was critical in the development of the different yield maps established to determine the level of consistency of management zones across crops over time. Several important concepts, such as data normalization, yield grid maps, inverse distance weighted and stability, were introduced throughout this research to: set the scale of measures to …


Ethics And Literature: Love And Perception In Henry James, Sarah Hamilton Jan 2004

Ethics And Literature: Love And Perception In Henry James, Sarah Hamilton

LSU Master's Theses

In this paper I argue for the value of literature in ethical instruction. Following Martha Nussbaum, I argue that literature often promotes the kind of context-specific judgment, respect for the cognitive value of the emotions and empathy for others that are foundational to the kind of ethical judgment Nussbaum and I support. Like Nussbaum, I find that Henry James's novels evince these same ethical values and that his novels, especially the novels of the late phase, are therefore useful for ethical instruction. Unlike Nussbaum, however, I do not believe that James portrays erotic love as an emotion that is incompatible …


Comparison Studies Of The Mechanistic Formation Of Polyhalogentaed Dibenzo-P-Dioxins And Furans From The Thermal Degradation Of 2-Bromophenol And 2-Chlorophenol, Catherine Spearing Evans Jan 2004

Comparison Studies Of The Mechanistic Formation Of Polyhalogentaed Dibenzo-P-Dioxins And Furans From The Thermal Degradation Of 2-Bromophenol And 2-Chlorophenol, Catherine Spearing Evans

LSU Doctoral Dissertations

Emissions of polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) and polybrominated dibenzo-p-dioxins and furans (PBDD/Fs) from hazardous waste incinerators, and many other sources for combustion have been considered environmentally hazardous and a major health threat. Recently, a growing number of materials containing brominated hydrocarbons, commonly used flame retardants, have been disposed in municipal and hazardous waste incinerators. This results in the increased potential for formation of PBDD/Fs and other hazardous combustion by-products. In contrast to chlorinated hydrocarbons, the reactions of brominated hydrocarbons have been studied only minimally. In fact, studies have shown that brominated phenols form higher yields of PBDD/Fs than the …


Dynamics Of Complex Polymer Solutions: Putting Diffusion To Work And Exploring Rigid Rod Diffusion, Garrett John Doucet Jan 2004

Dynamics Of Complex Polymer Solutions: Putting Diffusion To Work And Exploring Rigid Rod Diffusion, Garrett John Doucet

LSU Doctoral Dissertations

This dissertation is concerned with random coil and rodlike polymer diffusion in complex solutions. The development of fluorescence photobleaching recovery, FPR, as a technique to determine polymer molecular weight distributions by measuring the diffusion distribution and converting it to a molecular weight distribution using a calibration curve is first covered. Fluorescently tagged probes were individually dissolved in polymer solutions at negligible amounts and measured with FPR to construct the calibration curve of self-diffusion vs. molecular weight. Once calibration curves were constructed, bimodal distributions were separated using the matrices corresponding to the calibration curves. The diffusion of the probes and separation …


Construct Validation Of An Arabic Version Of The Learning Transfer System Inventory For Use In Jordan, Samer Abdelkarim Khasawneh Jan 2004

Construct Validation Of An Arabic Version Of The Learning Transfer System Inventory For Use In Jordan, Samer Abdelkarim Khasawneh

LSU Doctoral Dissertations

Organizations in Jordan have invested heavily in employee training. However, these training efforts may not be as effective. One area of particular interest is learning transfer, or the extent to which learning from training is applied on the job. Recent research efforts have led to the development of the Learning Transfer System Inventory (LTSI), the only valid and reliable measure of key transfer system factors. This study validated the constructs of the LTSI for use in Jordan. By doing so, HRD practitioners in Jordan can use such instrument to diagnose early problems with learning transfer, the key to training effectiveness …


The Interrelations Between Investor Beliefs, Information And Market Liquidity, Stephanie Yates Rauterkus Jan 2004

The Interrelations Between Investor Beliefs, Information And Market Liquidity, Stephanie Yates Rauterkus

LSU Doctoral Dissertations

I use two datasets to test the relation between trading volume, the heterogeneity of beliefs and the heterogeneity of belief revisions. The first dataset allows me to construct two groups that proxy for ‘holders’ and ‘non-holders’ of a traded asset. This construct allows me to test the relation between changes in trading volume and changes in the dispersion of beliefs both within and across these two groups. I examine changes in within- and across-group dispersion separately and simultaneously. The second dataset allows me to examine belief revisions more closely by analyzing only those prior and posterior beliefs surrounding an information …


Dna Binding Properties Of Histone-Like Protein Hu From Deinoccus Radiodurans Suggest Involvement In Dna Recombination, Sharmistha Ghosh Jan 2004

Dna Binding Properties Of Histone-Like Protein Hu From Deinoccus Radiodurans Suggest Involvement In Dna Recombination, Sharmistha Ghosh

LSU Doctoral Dissertations

The Histone-like protein HU is ubiquitous in eubacteria. Usually with a length of ~90 amino acids, they are predominantly homodimeric, with sequence and structural homology. Escherichia coli HU is involved in DNA repair and recombination. The crystal structure of Anabaena HU shows that it binds DNA with prolines intercalating into the DNA backbone, introducing two kinks at a spacing of 9 bp and bending the DNA through a variable angle of 105-140°. Deinococcus radiodurans is a gram positive mesophile, capable of reconstituting its genome from 1000-2000 double strand breaks incurred due to exposure to environmental extremes. In the first study, …


Asymptotic Laplace Transforms, Claudiu Mihai Jan 2004

Asymptotic Laplace Transforms, Claudiu Mihai

LSU Doctoral Dissertations

In this work we discuss certain aspects of the classical Laplace theory that are relevant for an entirely analytic approach to justify Heaviside's operational calculus methods. The approach explored here suggests an interpretation of the Heaviside operator ${cdot}$ based on the "Asymptotic Laplace Transform." The asymptotic approach presented here is based on recent work by G. Lumer and F. Neubrander on the subject. In particular, we investigate the two competing definitions of the asymptotic Laplace transform used in their works, and add a third one which we suggest is more natural and convenient than the earlier ones given. We compute …


Microhabitat Distribution And Demography Of Two Florida Scrub Endemic Plants With Comparisons To Their Habitat-Generalist Congeners, Satya Maliakal Witt Jan 2004

Microhabitat Distribution And Demography Of Two Florida Scrub Endemic Plants With Comparisons To Their Habitat-Generalist Congeners, Satya Maliakal Witt

LSU Doctoral Dissertations

I evaluated hypotheses regarding the nature of habitat specialization by comparing the microhabitat distribution and demography of L. cernua and P. basiramia, two Florida rosemary scrub habitat specialist species, with their habitat generalist congeners, L. deckertii and P. robusta. Specifically, I addressed the following two hypotheses: (1) that habitat specialist species may occur in a narrower range of microhabitat conditions than habitat generalist species, and (2) that demographic parameters of habitat specialist species may be more variable than those of their habitat generalist congeners. For each pair of congeners, I compared the microhabitat distributions, variation in vital rates and population …


The Use Of Altrenogest To Control Reproductive Function In Beef Cattle, Clarence Edward Ferguson Jan 2004

The Use Of Altrenogest To Control Reproductive Function In Beef Cattle, Clarence Edward Ferguson

LSU Doctoral Dissertations

There has been great controversy involving progesterone (P4) levels during early pregnancy in cattle. The objectives of these experiments were to determine the effect of an early low dose administration of P4 or altrenogest (ALT) on pregnancy rates in repeat breeder (RPB) females, if an increase in pregnancy rates could result from a direct effect of P4 on the embryo and if ALT could support pregnancy in the absence of a functional CL. Firstly, ALT was evaluated for use as a progestin in cattle by synchronizing estrus in beef heifers. There were no differences in the …


Synthesis, Separation And Reactivities Of Multidentate Phosphine Ligands And Investigation Into Dirhodium Hydroformylation And Hydrocarboxylation Catalysis, David Aubry Jan 2004

Synthesis, Separation And Reactivities Of Multidentate Phosphine Ligands And Investigation Into Dirhodium Hydroformylation And Hydrocarboxylation Catalysis, David Aubry

LSU Doctoral Dissertations

A dirhodium homogeneous hydroformylation catalyst based on a tetraphosphine ligand, rac-Et2PCH2CH2P(Ph)CH2P(Ph)CH2CH2PEt2, rac-et,ph-P4, is under investigation. The ligand synthesis produces a racemic mixture and a facile and efficient method of separation of the racemic and meso diastereomers was achieved through reaction of et,ph-P4 with two equivalents of NiCl2 in EtOH to yield an almost quantitatively isolable precipitate of meso-Ni2Cl4(et,ph-P4) and the soluble rac-Ni2Cl4(et,ph-P4). Subsequent cyanolysis of these complexes liberates the et,ph-P4 ligand, and the …


Non-Linear Development Of The Secular Bar-Mode Instability In Rapidly Rotating Neutron Stars, Shangli Ou Jan 2004

Non-Linear Development Of The Secular Bar-Mode Instability In Rapidly Rotating Neutron Stars, Shangli Ou

LSU Doctoral Dissertations

We present results from investigations of the nonlinear development of the secular bar-mode instability that is driven by gravitational radiation-reaction (GRR) forces in rotating neutron stars. Our fully three-dimensional hydrodynamical simulations have shown that, in the absence of any competing viscous effects, initially uniformly rotating axisymmetric n=1/2 polytropic stars with a ratio of rotational to gravitational potential energy greater than the critical limit are driven by GRR forces to a bar-like structure, as predicted by linear theory. The pattern frequency of the bar slows to nearly zero, that is, the bar becomes almost stationary as viewed from an inertial frame …


Synthesis And Characterization Of Superparamagnetic Silica--Homopolypeptide Composite Particles, Sibel Turksen Jan 2004

Synthesis And Characterization Of Superparamagnetic Silica--Homopolypeptide Composite Particles, Sibel Turksen

LSU Doctoral Dissertations

Hierarchical construction and characterization of core-shell composite particles of interest are presented. The research described shows interest in new types of polymers that provide chirality and responsiveness which have been ignored for so long. The general synthetic design described in this document can be readily used as a model for other systems. Core-shell composite systems of interest consist of silica or silica-coated cobalt cores grafted with a homopolypeptide shell, mostly poly(epsilon-carbobenzyloxy-L-lysine) or poly(gamma-benzyl-L-glutamate). Core particles were decorated with amino groups through a silylation reaction. The amino groups initiated the polymerization (with attachment) of N-carboxyanhydride (NCA) monomers, resulting in a homopolypeptide …


Small And Large Strain Monitoring Of Unsaturated Soil Behavior By Means Of Multiaxial Testing And Shear Wave Propagation, Oscar F. Porras Ortiz Jan 2004

Small And Large Strain Monitoring Of Unsaturated Soil Behavior By Means Of Multiaxial Testing And Shear Wave Propagation, Oscar F. Porras Ortiz

LSU Doctoral Dissertations

The deformation and strength behavior of dry and saturated soils is controlled by the effective stresses as defined by Terzaghi. However, Terzaghi’s definition of the effective stresses fails for unsaturated soils, as capillarity force influence is also important. The effects of capillarity forces in soil are evaluated by the concept of matrix suction. Several techniques are used to evaluate soil suction however their applications involve difficult calibrations and tedious methodology. Furthermore, suction is a microscopic property and it is influenced by interparticle soil attraction, which can change by sampling disturbance. This research program evaluates the effect of suction on stiffness …


The Discipline And Disciplining Of Margaret Sanger: Us Birth Control Rhetoric In The Early Twentieth Century, C. Wesley Buerkle Jan 2004

The Discipline And Disciplining Of Margaret Sanger: Us Birth Control Rhetoric In The Early Twentieth Century, C. Wesley Buerkle

LSU Doctoral Dissertations

Margaret Sanger's rhetoric in the US birth control movement demonstrates the social forces that act upon rhetors and women's bodies, conforming both to established gender norms even as they attempt to violate those standards. This project studies Sanger's birth control rhetoric to understand how her arguments for women's right to contraception conformed women's bodies to traditional feminine notions despite her early efforts to contradict such dictates of domesticity. Research on nineteenth-century feminist rhetors demonstrates a pattern of women challenging feminine ideals by speaking publicly but replicating the familiar themes that women must care for others. To explain such a pattern, …
