Linguistic And Cultural Immersion And Second Language Acquisition: International Young Student Exchange., Rosita Mira Maristany Jan 1995

Linguistic And Cultural Immersion And Second Language Acquisition: International Young Student Exchange., Rosita Mira Maristany

LSU Historical Dissertations and Theses

The trend in foreign language learning reflects a move from "fragmented" language to "whole" language (Rigg 1991). It includes the individual as well as the social aspect of language acquisition; and the integration of language and culture. Student international exchange programs provide the ideal atmosphere for "whole" language learning and the integration of language and culture in total language and cultural immersion. Most research in international student exchange programs described the organization of the program or addressed a particular variable. There is a need for integrative "whole" research rather than "fragmented" research. The method chosen as most appropriate for this …

The Habitat, Ecology And Epidemiology Of Eastern Equine Encephalomyelitis In Southeast Louisiana., Kenny L. Samui Jan 1995

The Habitat, Ecology And Epidemiology Of Eastern Equine Encephalomyelitis In Southeast Louisiana., Kenny L. Samui

LSU Historical Dissertations and Theses

Many unanswered questions on the epidemiology and ecology of eastern equine encephalomyelitis (EEE) still preclude a complete understanding of its natural history. Among these are the distribution and epidemic vectors of EEE virus (EEEV) in different regions, habitats, and foci; its inter-epidemic maintenance, and overwintering mechanisms. Phase 1 of a research project designed to find answers to the above questions with regard to southeast Louisiana was conducted over 1992 and 1993, and consisted of several individual studies. These included 3 mosquito studies to determine major horse- and bird-feeding mosquito species that could be the EEEV epidemic vectors in southeast Louisiana; …

A Formal Methodology For Deriving Purely Functional Programs From Z Specifications Via The Intermediate Specification Language Funz., Linda Bostwick Sherrell Jan 1995

A Formal Methodology For Deriving Purely Functional Programs From Z Specifications Via The Intermediate Specification Language Funz., Linda Bostwick Sherrell

LSU Historical Dissertations and Theses

In recent years, both formal methods and software reuse have been increasingly advocated as a means of alleviating the ills of the software crisis. During this same time period, purely functional programming languages, which have a long history in the realm of rapid prototyping, have emerged as a viable medium for real-world applications. Since these trends are likely to continue, this work describes a methodology that facilitates the derivation of purely functional programs from existing Z specifications. A unique aspect of the methodology is its incorporation of an intermediate specification language (FunZ) during the design phase of software development. Most …

Rural Industry And Rural Development In China: The Role Of Geography, Transportation, And Policy In Jiangsu Province., Shew-Jiuan B. Su Jan 1995

Rural Industry And Rural Development In China: The Role Of Geography, Transportation, And Policy In Jiangsu Province., Shew-Jiuan B. Su

LSU Historical Dissertations and Theses

A significant change in China since late 1978 is the development of rural industry (also township-village enterprise, or TVE). Rural industry is particularly important in light of China's current policy of socio-economic decentralization. Rural industry not only absorbs surplus labor and pushes the increases of agricultural productivity, it also revitalizes China's previously lethargic economy. In this study, variations in employment, production value, and economic efficiency of rural industry are analyzed in terms of geographical, transportation and policy determinants at the county/city level of Jiangsu Province in China. Rural industry's contribution to agricultural and rural welfare activities, and how levels of …

Genotypic Variation In Sweetpotato Ipomoea Batatas (L.) Lam. Clones., Arthur Quejada Villordon Jan 1995

Genotypic Variation In Sweetpotato Ipomoea Batatas (L.) Lam. Clones., Arthur Quejada Villordon

LSU Historical Dissertations and Theses

Arbitrarily-primed PCR-based assays established the presence of sweetpotato intra-clonal genetic variability. These DNA polymorphism assays provided benchmark information regarding cultivar genetic uniformity in sweetpotato foundation seed programs. Arbitrarily-primed markers were also used to compare the genetic uniformity among sweetpotato clones derived conventionally, i.e., through adventitious sprouts, and nodally-based propagation systems. Initially, 38 primers generated 110 scorable DNA fragments using two virus-indexed plants from each clone source. Twenty-one bands (18.6%) were scored as putative polymorphic markers based on the presence or absence of amplified products. A subset of 14 marker loci generated by four selected primers was used to further assay …

Studies Of V-Nitrogenase From Azotobacter Vinelandii: Structural Variations, Temperature And Solvent Effects., Carol Zembiak Blanchard

LSU Historical Dissertations and Theses

When Q-Sepharose was used in the purification of the V-nitrogenase proteins from Azotobacter vinelandii, an increase in resolution was observed which resulted in a separation of the nitrogenase component 1 protein (Av1$\sp\prime$) into two forms, labeled Av1$\sp\prime\sb{\rm A}$ and Av1$\sp\prime\sb{\rm B}.$ Even though both forms possessed the same enzymatic behavior, Av1$\sp\prime\sb{\rm A}$ exhibited a lower specific activity and migrated during gel filtration with an apparent lower molecular weight than Av1$\sp\prime\sb{\rm B}.$ Furthermore, SDS-polyacrylamide gel electrophoresis showed different relative compositions of the two major subunits of both forms with Av1$\sp\prime\sb{\rm A}$ possessing a trimer $(\alpha\beta\sb2)$ pattern compared to the tetramer $(\alpha\sb\beta\sb2)$ …

Phase Space Structures In Chaotic Quantum Dynamics., Barbara Smetana Helmkamp Jan 1995

Phase Space Structures In Chaotic Quantum Dynamics., Barbara Smetana Helmkamp

LSU Historical Dissertations and Theses

I compare the quantum and classical dynamics of a particle moving in a cosine potential while subject to a time-dependent force. I concentrate here on the behavior of an initially well-localized wave packet at times before the classically chaotic motion is fully developed. I find that the quantum and classical dynamics are indistinguishable well beyond the Ehrenfest time where the wave packet delocalizes. The quantum and classical descriptions first differ precisely when the classical probability density is folded in the vicinity of a hyperbolic fixed point. At this point, the wave function acquires a nodal structure which I show to …

Molecular Cloning, Sequencing, And Regulation Of The Rhodobacter Capsulatushemb Gene., Karl Joseph Indest Jan 1995

Molecular Cloning, Sequencing, And Regulation Of The Rhodobacter Capsulatushemb Gene., Karl Joseph Indest

LSU Historical Dissertations and Theses

The common tetrapyrrole pathway in the photosynthetic bacterium, Rhodobacter capsulatus, is responsible for the synthesis of bacteriochlorophyll, heme, vitamin B-12, and siroheme. The common portion of this pathway is regulated up to 100-fold by changes in oxygen tension. This regulation is accomplished by controlling the intracellular level of porphobilinogen. One way in which porphobilinogen levels could be controlled is by regulating the synthesis of porphobilinogen. Porphobilinogen synthase, encoded by the hemB gene, is the second enzyme in the common tetrapyrrole pathway that catalyzes the dimerization of 5-aminolevulinic acid to form the monopyrrole porphobilinogen. In order to further investigate the mechanism …

Sediment Retention In A Bottomland Hardwood Wetland In Eastern Arkansas., Barbara A. Kleiss Jan 1995

Sediment Retention In A Bottomland Hardwood Wetland In Eastern Arkansas., Barbara A. Kleiss

LSU Historical Dissertations and Theses

One of the often-stated functions of wetlands is their ability to remove sediments and other particulates from water, thus improving water quality in the adjacent aquatic system. However, actual rates of suspended sediment removal have rarely been measured in freshwater wetland systems. To address this issue, suspended sediment dynamics were measured in a 85-km$\sp2$ bottomland hardwood (BLH) wetland adjacent to the highly turbid Cache River in eastern Arkansas during the 1988-90 water years. A suspended sediment mass balance was calculated using depth-integrated, flow-weighted daily measurements at wetland inflow and outflow points. Over the three year period, suspended sediment load decreased …

Parallel Algorithms For Constructing Convex Hulls., Jigang Liu Jan 1995

Parallel Algorithms For Constructing Convex Hulls., Jigang Liu

LSU Historical Dissertations and Theses

For a given set of planar points S, the convex hull of S, CH(S), is defined to be a list of ordered points which represents the smallest convex polygon that contains all of the points. The convex hull problem, one of the most important problems in computational geometry, has many applications in areas such as computer graphics, simulation and pattern recognition. There are two strategies used in designing parallel convex hull algorithms. One strategy is the divide-and-conquer paradigm. The disadvantage to this strategy is that the recursive merge step is complicated and difficult to implement on current parallel machines. The …

Elucidation And Modulation Of Ceb Metabolism In Fischer 344 Rats: Possible Mechanisms Of Toxicity And Anticarcinogenicity., Judith Sara Prescott-Mathews

LSU Historical Dissertations and Theses

The ability of acivicin (AT-125), probenecid, and aminooxyacetic acid (AOAA), to ameliorate 1-cyano-3,4-epithiobutane (CEB)-induced nephrotoxicity and karyomegaly was evaluated by histopathology and histomorphometry. Epithelial cell necrosis and karyomegaly were observed in the renal proximal tubules at 24 and 48 hours in all of the treated groups with the exception of AOAA pretreated rats at 24 hours. A predominant urinary metabolite of CEB was identified as the mercapturate, N-acetyl-S-(4-cyano-2-thio-1-butyl)-cysteine. Evidence of other urinary metabolites was also demonstrated. The influence of inhibitors on the GSH-enhancing effect of CEB was determined through measurement of tissue GSH levels and $\gamma$-glutamyl-cysteine synthetase (GCS) activity. Hepatic …

The Association Between Anticyclonic Weather Changes Over The Central Gulf Coast And Large-Scale Circulation Changes., Robert V. Rohli Jan 1995

The Association Between Anticyclonic Weather Changes Over The Central Gulf Coast And Large-Scale Circulation Changes., Robert V. Rohli

LSU Historical Dissertations and Theses

Trends in winter extratropical anticyclonic weather type frequencies (1961-1989) were examined for New Orleans, Louisiana, in order to identify the effects of global climatic change on regional-scale circulation changes over the central Gulf Coast. The number of days dominated by surface continental anticyclones (CH days) was found to have decreased significantly over time, while Pacific anticyclone (PH) frequency showed significant temporal increase. Therefore, 50 kPa geopotential height variability, 50 kPa geostrophic flow, and surface atmospheric variables were examined to determine whether changes in these features have accompanied the frequency changes in weather types. Prior to PH days, areas of greatest …

X-Ray Absorption And Electron Paramagnetic Resonance Studies Of Azotobacter Vinelandii Nitrogenase., Roland Carroll Tittsworth Jan 1995

X-Ray Absorption And Electron Paramagnetic Resonance Studies Of Azotobacter Vinelandii Nitrogenase., Roland Carroll Tittsworth

LSU Historical Dissertations and Theses

Fe K-edge Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy was used to investigate the metal-cluster structure of both the Mo-containing (Av1) and V-containing (Av1$\sp\prime$) nitrogenase component 1 proteins of Azotobacter vinelandii in their as-isolated and thionine-oxidized states. Using the EXAFS data, plausible distance assignments were made for the cofactor clusters. It was shown that small but consistent distance changes occur in both Av1 and Av1$\sp\prime$ upon thionine oxidation. Furthermore, the EXAFS of Av1$\sp\prime$ is very similar to that of Av1, supporting the proposal that the two proteins have homologous metal cluster structures. Fe K-edge and Mo K-edge EXAFS were used …

The Contextual Interference Effect In Learning Parameters Of The Generalized Motor Program., Hiroshi Sekiya

LSU Historical Dissertations and Theses

Four experiments examined the generalizability of the contextual interference (CI) effect. In all experiments, to examine the locus of the CI effect measures assessing generalized motor program (GMP) learning and parameter learning were used in addition to a measure of general performance. In the first two experiments, variations of a timing tapping task, which were controlled by either different GMPs (Experiment 1) or the same GMP (Experiment 2), were learned under either blocked (low CI) or serial (high CI) practice. The CI effect was found for the general performance measure regardless of the task characteristics, contrary to Magill and Hall's …

Performing The Community, Telling The Self: Storytelling By Members Of A Group Home For Men With Mental Retardation., Sharon Elizabeth Croft Jan 1995

Performing The Community, Telling The Self: Storytelling By Members Of A Group Home For Men With Mental Retardation., Sharon Elizabeth Croft

LSU Historical Dissertations and Theses

This study uses an ethnographic approach to examine the stories told by members of a group home for men with mental retardation. The author contends that the culture of the group home works to constrain how group home members interact within this community. The author argues, however, that despite the cultural constraints, the men use storytelling to establish their individuality, even though the stories themselves, in their content and in the performance of their telling, often reify cultural constraints and their cultural constructions. The author recounts how she, as ethnographer, interacted within this community. After identifying, describing, and analyzing eight …
