A Spatial Analysis Of Variation In Rural Real Estate Prices Across Homogeneous Land Market Areas In Louisiana., Gary A. Kennedy

LSU Historical Dissertations and Theses

Rural land, exchanged for its productive or consumptive value, is considered to be a differentiated product with varying characteristics. Multivariate procedures and hedonic price analysis were used to evaluate the impact of rural land characteristics on rural land prices across homogeneous rural land market areas in Louisiana. Multivariate methods of principal component analysis and cluster analysis were used to group 59 Louisiana parishes into eight rural land submarkets based on 13 physical and socio-economic variables. Using a mail survey technique, 948 Louisiana rural land sales were collected. A geographic information system (GIS) analysis of these 948 sales indicated that sales …

Experimental And Numerical-Modeling Studies Of A Field-Scale Hazardous Waste Rotary Kiln Incinerator., Allen Lee Jakway

LSU Historical Dissertations and Theses

A comprehensive study of rotary kiln incineration is ongoing at Louisiana State University. Through experimentation at all levels and numerical modeling, the underlying physical processes are searched out and studied with the intent to improve the understanding of how rotary kiln incinerators process waste with the eventual goal of creating a fully predictive numerical model. The experimental work presented here focuses on mapping combustion gas temperature and, for the first time, velocity fields of a field-scale, industrial incinerator. Measurements are made at multiple points across an upper quadrant of the kiln near its exit using a bidirectional pressure probe, suction …

The primary purpose of this study was to compare novice, experienced, and expert professional nurses in terms of their critical thinking ability. The study also sought to identify the influence of selected individual characteristics on the critical thinking ability of professional nurses. Three samples of professional nurses, representing three levels of experience and skill, were selected for use in this study. Subjects included a convenience sample of 38 novice nurses (graduating seniors in a generic baccalaureate nursing program), 42 randomly selected experienced nurses, and a purposive sample of 48 expert nurses recognized as exemplary by their peers. A three-part instrument …

Differential Item Functioning In Performance Assessments: A Comparison Of Three Procedures., Hae-Seong Park

LSU Historical Dissertations and Theses

As performance assessments grow in popularity, it becomes increasingly important to investigate the effect of such assessments on various population subgroups. The purpose of this study was to investigate the relative empirical power of three popular statistical procedures (an extension of the generalized Mantel-Haenszel procedure, Logistic Discriminant Function Analysis, and a combined t-test procedure) in identifying polytomously scored items that function differentially for two subgroups of examinees. In the Monte Carlo study computer simulations were conducted to study the behavior of these procedures for identifying items exhibiting varying degrees of differential-item functioning (DIF). Each statistic was converted to a probability …

Effects Of Exogenous Female Sex Hormones On Food Intake, Macronutrients And Body Weight In The Ovariectomized Postbreeder Female Rat., Jan Barton Hamilton

LSU Historical Dissertations and Theses

Hormone replacement therapy (HRT) is chosen by a growing segment of the postmenopausal population. Mid-life body weight gain is perceived to increase further with exogenous HRT. To examine hormonal effects on caloric intake (CI), carbohydrate (CHO), FAT, protein (PRO), chocolate and body weight (BW) in a female model, Sprague-Dawley postbreeder (n = 55) rats (10 mos., 10 litters of pups) were ovariectomized (OV) and implanted with 17 $\beta$ estradiol (E) and/or progesterone (P), or placebo in three separate studies (phases) of 10 days each. Uterine weights (p =.0001) and radioimmunoassay confirmed hormonal bioactivity. The sham (S) group with placebo implant …

Ipcc++: A Concurrentc++ For Centralized And Distributed Memory Models., Shelly S. Stubbs

LSU Historical Dissertations and Theses

InterProcess Communication with C++, (IPCC++), is a concurrent object-oriented programming language that supports concurrency for centralized and distributed memory models while maintaining the high level of abstraction associated with object-oriented languages. The IPCC++ language model is a natural extension of the C++ programming language which introduces and supports the following features of concurrency: process concept, mechanism for process instantiation, static and dynamic process declaration, inter-object concurrency, monitor structure, condition variable, socket structure, typed message passing interprocess communication, synchronous and asynchronous communication, client/server paradigm, and run-time communication error detection. Features of concurrency are introduced as complete objects using the primitives of …

Interleukin-2 Promoter/Enhancer Controlled Expression Of A Synthetic Cecropin-Class Lytic Peptide In Transgenic Mice., William Andrew Reed

LSU Historical Dissertations and Theses

Pathogens continue to evolve mechanisms of avoiding efforts to control their spread. Treatment with exogenous antimicrobials often occurs after the pathogen has reproduced extensively in the host. In the case of mammals, the immune system may not be fully mobilized for 72 h after the detection of foreign antigen. However, within 24 h of presentation of antigen by antigen-presenting cells to resting thymus-derived lymphocytes IL2 is produced. A class of broad spectrum antimicrobial peptides which constitute a major component of the insect immune system has been described and characterized. Called "cecropins", they are relatively non-toxic to normal cells from multicellular …

The South And American Foreign Policy, 1894-1904: Regional Concerns During The Age Of Imperialism., Marshall E. Schott

LSU Historical Dissertations and Theses

After the depression of 1893, some New South prophets advocated a more assertive, foreign policy as a means to attain regional economic uplift. With the objective of obtaining overseas markets, some of the prophets even supported the use of force to create American colonies as an appropriate goal of American foreign policy. The acquisition of new territories, and hence, new markets, the prophets maintained, would be an economic boon to southern producers of cotton, textiles, and other goods. And the economic stimulus accompanying an increase in foreign trade would lift the region out of poverty, promote the growth of southern …

Cloning, Expression, Primary Structure, And Insertion Mutagenesis Of The Pyruvate Formate-Lyase Enzyme Of Aeromonas Hydrophila., Mohamed Alaa Eldin Abdelalim Awad

LSU Historical Dissertations and Theses

The pyruvate formate-lyase enzyme (Pfl), a key enzyme in alcoholic fermentation, catalyzes the anaerobic conversion of pyruvate into acetyl-CoA and formate in prokaryotes. The pyruvate formate-lyase gene (pfl) of the facultative anaerobe Aeromonas hydrophila was cloned and sequenced. Subsequently, the Pfl was characterized based on the deduced amino acid sequence and evaluated in vivo following insertion mutagenesis. Finally, the pathogenesis of a defined mutant was compared to wild type A. hydrophila in channel catfish. The pfl of A. hydrophila was identified from two recombinant pBluescript SK(-) clones excised from a $\lambda$ ZAP II phage library. Both clones carried the same …

Comparison Of Continuous Records Of Near-Bottom Dissolved Oxygen From The Hypoxia Zone Along The Louisiana Coast, Nancy N. Rabalais, William J. Wiseman, R. Eugene Turner

Faculty Publications

Oxygen depletion is a seasonally dominant feature of the lower water column on the highly-stratified, riverine-influenced continental shelf of Louisiana. The areal extent of hypoxia (bottom waters ≤2 mg l−1 dissolved oxygen) in mid-summer may encompass up to 9,500 km2, from the Mississippi River delta to the upper Texas coast, with the spatial configuration of the zone varying interannually. We placed two continuously recording oxygen meters (Endeco 1184) within 1 m of the seabed in 20-m water depth at two locations 77 km apart where we previously documented midsummer bottom water hypoxia. The oxygen meters recorded considerably different oxygen conditions …

Ecological Impacts Of Historic And Prehistoric Hurricanes On Horn Island, Mississippi, Kari Gathen

LSU Historical Dissertations and Theses

Hurricanes play an important role in the ecology and geomorphology of the northern Gulf of Mexico coast. In order to study the impact of hurricanes on barrier island vegetation, the sedimentary and fossil pollen records taken from cores in three ponds on Horn Island, Mississippi were examined to establish a record of ecological and geomorphological disturbance on Horn Island. Surface samples taken from the bottom of 15 ponds and 3 lagoons, delineated as fresh or brackish according to salinity test results, provide the modern vegetational analog to compare with the fossil pollen record using a discriminant analysis. Discriminant analysis results …

Faculty Publications

Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range Q2 ≥ 10 GeV2 using the ZEUS detector. A comparison is made between events with and without a large rapidity gap between the hadronic system and the proton direction. The energy flows, corrected for detector acceptance and resolution, are shown for these two classes of events in both the HERA laboratory frame and the Breit frame. From the differences in the shapes of these energy flows we conclude that QCD radiation is suppressed in the large-rapidity-gap eents compared to the events …

Cloning And Functional Characterization Of Lcr-F1: A Bzip Transcription Factor That Activates Erythroid-Specific, Human Globin Gene Expression, John J. Caterina, David Donze, Chiao Wang Sun, Dominic J. Ciavatta, Tim M. Townes

Faculty Publications

DNase I hypersensitive site 2 (HS 2) of the human β-globin Locus Control Region (LCR) directs high level expression of the β-globin gene located 50 kilobases downstream. Experiments in cultured cells and in transgenic mice demonstrate that duplicated AP1-like sites in HS 2 are required for this powerful enhancer activity. A cDNA clone encoding a basic, leucine-zipper protein that binds to these sites was isolated and designated Locus Control Region-Factor 1 (LCR-F1). This protein is a member of a new family of regulatory factors that contain a 63 amino acid 'CNC domain' overlapping the basic region. This domain is approximately …

Multiple Elements In Human Β-Globin Locus Control Region 5′ Hs 2 Are Involved In Enhancer Activity And Position Independent, Transgene Expression, John J. Caterina, Dominic J. Ciavatta, David Donze, Richard R. Behringer, Tim M. Townes

Faculty Publications

The human β-globin Locus Control Region (LCR) has two important activities. First, the LCR opens a 200 kb chromosomal domain containing the human ε-, γ- and β-giobin genes and, secondly, these sequences function as a powerful enhancer of ε-, γ- and β-globin gene expression. Erythrold-specific, DNase I hypersensitive sites (HS) mark sequences that are critical for LCR activity. Previous experiments demonstrated that a 1.9 kb fragment containing the 5′ HS 2 site confers position-independent expression in transgenic mice and enhances human β-giobin gene expression 100-fold. Further analysis of this region demonstrates that multiple sequences are required for maximal enhancer activity; …

Backfilling Canals To Restore Wetlands: Empirical Results In Coastal Louisiana, R. Eugene Turner, James M. Lee, Christopher Neill

Faculty Publications

Wetland restoration is largely a developing science and engineering enterprise. Analyses of results are too few and constrained to observations over a few years. We report here on the effectiveness of one restoration technique used sparsely in coastal Louisiana for several decades. Canals have been dredged in coastal Louisiana wetlands since 1938 for oil and gas exploration and extraction. These canals are typically dredged to 2.5 m depth and are 20 to 40 m wide. Canal lengths vary from 100 m to several 1000s m in the case of outer continental shelf pipeline canals that cross the wetlands.

Today, thousands …

Determination Of Radiative Lifetimes Of Excited States In Neutral Gold Using Time-Resolved Vacuum-Ultraviolet Laser Spectroscopy, M. B. Gaarde, R. Zerne, Luo Caiyan, Jiang Zhankui, J. Larsson, S. Svanberg

Faculty Publications

Natural radiative lifetimes of the states in the highly perturbed 5d10np 2P sequence in neutral gold, Au i, for n=69, as well as of four of the perturbing 5d96s6p 2P states, have been measured. This was done by direct excitation from the ground state with short-pulse vacuum-ultraviolet laser light and time-resolved detection of the laser-induced fluorescence. We found the lifetimes to be (6p 2P1/2)=6.2(2) ns, (6p 2P3/2)=4.7(2) ns, (7p 2P1/2)=6.4(7) ns, (7p 2P3/2)=5.3(7) ns, (8p 2P1/2)=63(3) ns, (8p 2P3/2)=24(2) ns, (9p 2P1/2)=28(2) ns, and (9p 2P3/2)=75(4) ns. For the perturbing states (two states of each term have been observed) we …
