Female High School Biology Students' Biofilm -Focused Learning: The Contributions Of Three Instructional Strategies To Patterns In Understanding And Motivation., Jo Dale Hill Ales

LSU Historical Dissertations and Theses

This exploratory study examined three instructional strategies used with female high school biology students. The relative contributions of the strategies to student understanding of microbiology and motivation in science were analyzed. The science education community targeted underachievement in science by implementing changes in content and practices (NRC, 1996). Research suggested that teachers facilitate learnirig environments based on human constructivism (Mintzes, Wandersee, & Novak, 1997) that is rooted in meaningful learning theory (Ausubel, Novak & Hanesian, 1978). Teachers were advised to use both visual and verbal instructional strategies (Paivio, 1983) and encourage students to construct understandings by connecting new experiences to …


Politics And Philosophy In The Writings Of Robert Penn Warren., Billy Berryhill Jan 2000

Politics And Philosophy In The Writings Of Robert Penn Warren., Billy Berryhill

LSU Historical Dissertations and Theses

Robert Penn Warren is generally regarded as one of America's preeminent men of letters in the twentieth century. In his poetry and novels-as well as his historical essays, literary and social criticism, biographies, and other non-fiction---Warren often addressed political themes. This study of the role of political ideas in Warren's writings begins with his concept of the "philosophical novelist" who consciously incorporates ideas into fiction. An examination of Warren's own essays about his novel All the King's Men provides a useful illustration of the concept and introduces the reader to two key themes that pervade all of his writings: first, …


A Canonical Description Of The Plancherel Measure For A General Two-Step Free Nilpotent Lie Group., Chin-Te Chu Jan 2000

A Canonical Description Of The Plancherel Measure For A General Two-Step Free Nilpotent Lie Group., Chin-Te Chu

LSU Historical Dissertations and Theses

In this work on g=Fn,2 , free 2-step nilpotent Lie algebra on n generators, we use the group of automorphisms to give a basis-free description of the Fourier Inversion Formula, thereby generalizing and strengthening an example discussed by Corwin & Greenleaf. In the Introduction we discuss Example 4.3.14 in Corwin & Greenleaf's book. It demonstrates how different bases of F3,2 lead to different inversion formulas. But the third "more" invariant formula describes Plancherel measure on a support expressed in terms of rotations, dilations, and translations. Actually it is not canonical since it still depends on choices of bases for F3,2 …


Efficient Checkpointing For Heterogeneous Collaborative Environments: Representation, Coordination, And Automation., Kasidit Chanchio Jan 2000

Efficient Checkpointing For Heterogeneous Collaborative Environments: Representation, Coordination, And Automation., Kasidit Chanchio

LSU Historical Dissertations and Theses

Checkpointing can be used to adapt resource utilization in heterogeneous distributed environments. In checkpointing, the state of a process is captured and later restored on a computer to restart execution from the point where the state capturing had occurred. Such capability can be applied to process migration for which resource utilization is adapted toward high-performance by moving a running process from one computer to another. For a heterogeneous environment, problems in checkpointing can be categorized into three domains regarding mechanisms to capture and restore the execution state, memory state, and communication state of a process. Although a few solutions have …

Luis De Unzaga And Bourbon Reform In Spanish Louisiana, 1770--1776., Julia Carpenter Frederick Jan 2000

Luis De Unzaga And Bourbon Reform In Spanish Louisiana, 1770--1776., Julia Carpenter Frederick

LSU Historical Dissertations and Theses

Previous histories of the establishment of Spanish rule in Louisiana have centered primarily on its first two officials, Governor Antonio de Ulloa and Captain-General Alejandro O'Reilly. This work focuses on Luis de Unzaga y Amezaga, governor of Spanish Louisiana from 1770 to 1776. It challenges previous interpretations of Unzaga's tenure which have traditionally viewed the Bourbon Reforms as detrimental to the colony and viewed the governor as merely benign and transitional in the colony's history. Comparison of shipping records and governor's records from Cuba and Louisiana indicate that the colony actually maintained the same volume of shipping with Havana that …


Simulating Household Travel Survey Data In Metropolitan Areas., Stephen Peter Greaves Jan 2000

Simulating Household Travel Survey Data In Metropolitan Areas., Stephen Peter Greaves

LSU Historical Dissertations and Theses

This dissertation proposes and tests a new approach for developing the travel survey data required for use in regional travel-demand modeling applications. Using local sociodemographic information in conjunction with a national travel survey, a simulation procedure is developed to create a synthetic household travel survey data set. The simulation procedure is tested in a region that has completed a recent travel survey---this provides a direct source of comparison for the merit of the approach. Comparisons of salient trip characteristics (trip frequencies, mode shares, departure times, and reported trip lengths) and travel-demand models estimated with these synthetic data suggest the approach …

Molecular Systematics And Historical Biogeography Of The Tree Shrews (Tupaiidae)., Kwai Hin Han Jan 2000

Molecular Systematics And Historical Biogeography Of The Tree Shrews (Tupaiidae)., Kwai Hin Han

LSU Historical Dissertations and Theses

This dissertation examined the molecular systematics and historical biogeography of tree shrews (Tupaiidae). Comparison of cytochrome b sequences and DNA hybridization data suggests that cytochrome b sequences evolved 7.9 to 13.4 times faster than single-copy nuclear DNA. These two data sets are taxonomically congruent. They indicate that the Mindanao tupaiid Urogale everetti is a member of Tupaia, and that there is lineage-based variation in rates of evolution among the tupaiids. A new species of Tupaia from Sarawak (Malaysia), T. stuebingi, was described using morphological, ecological, and cytochrome b sequence data. This lowland species is generally similar in size to the …

A Methodology To Support The Maintenance Of Object -Oriented Systems Using Impact Analysis., Michael Alan Hoffman Jan 2000

A Methodology To Support The Maintenance Of Object -Oriented Systems Using Impact Analysis., Michael Alan Hoffman

LSU Historical Dissertations and Theses

Object-Oriented (OO) systems are difficult to understand due to the complex nature of the relationships that object-orientation supports. Inheritance, polymorphism, encapsulation, information hiding, aggregation, and association combine to make maintenance of OO systems difficult. Due to the presence of these characteristics in OO systems, maintenance activities on OO systems often have unexpected or unseen effects on the system. These effects can ripple through system components, complicating maintenance and testing of the system. The ability to trace the effects of maintenance provides the maintainer with knowledge that assists in debugging and testing modified and affected components. In this research, we show …

Extended Topics In The Integration Of Data Envelopment Analysis And The Analytic Hierarchy Process In Decision Making., Tae-Sung Kim

LSU Historical Dissertations and Theses

The Analytic Hierarchy Process (AHP) is a procedure, which can only consider relative priorities as estimated by decision-makers. A Data Envelopment Analysis (DEA) model is a data-oriented approach for evaluating the relative efficiency of a group of entities referred to as Decision Making Units (DMUs). This research work integrates and combines positive aspects of AHP's estimated qualitative data and DEA's quantitative data. This combination is accomplished by specifying two variants of the DEA methodology for selection of the best DMU. Initially the priority weights of AHP are integrated with the DEA methodology to provide results that are logic based. Next, …


Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe Jan 2000

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe

LSU Historical Dissertations and Theses

Obesity, a recognized health problem, is associated with cardiovascular disease, diabetes and hypertension. Removal of adrenal steroids by adrenalectomy (ADX) slows the development of obesity. Leptin decreases food intake through effects initiated by activation of the JAK-STAT pathway. Defects in leptin signaling lead to obesity, which is associated with hyperleptinemia and leptin resistance. In chapter 4, leptin induces phosphoenolpyruvate carboxykinase (PEPCK) mRNA expression and increases glucose production in hepatocytes from lean but not obese Zucker rats. This suggests that hyperleptinemia in obesity causes hyperglycemia. In chapter 5, ADX decreased the levels of PEPCK mRNA, and increased leptin receptor mRNA expression …
