A Methodological Examination Of Naturally Occurring School Improvement In Louisiana Schools., John Albert Freeman
A Methodological Examination Of Naturally Occurring School Improvement In Louisiana Schools., John Albert Freeman
LSU Historical Dissertations and Theses
The study was conducted as an exploratory investigation of naturally occurring school improvement, which refers to improvement in a school's effectiveness status that is achieved without external change forces. The research design for the study used mixed methodologies divided into three phases to identify and examine schools that improved longitudinally in a "natural" environment. Phase I utilized regression (ordinary least squares) methods to create a database containing all elementary schools in Louisiana, categorized by their level of change. As a result, some 20% of the schools in Louisiana were identified as having improved over a three-year period. This approximated an …
Pure Framed Braids And 3-Manifolds., Jonathan Natov
Pure Framed Braids And 3-Manifolds., Jonathan Natov
LSU Historical Dissertations and Theses
This dissertation looks at representations of framed pure braids and compact orientable three manifolds. A representation, $\Phi:Z\sp{n}\oplus P\sb{n}\to \Gamma\sb{n},$ is constructed from the framed pure braid group on n strands to the mapping class group on a surface of genus n. The representation is used to obtain a presentation of the fundamental group. The representation, like that of (M-P), is compatible with Heegaard and Surgery descriptions. An algorithm is presented for transforming mapping class group elements to a stably equivalent pure framed braid, under the correspondence given by the representation. A geometric description, using the representation, is given for multiplication …
The Role Of The Unit As A Cognitive Bridge Between Additive And Multiplicative Structures., Nancy Sutton Alexander
The Role Of The Unit As A Cognitive Bridge Between Additive And Multiplicative Structures., Nancy Sutton Alexander
LSU Historical Dissertations and Theses
The rational number domain is known for the great difficulties it presents for students and teachers. As students construct knowledge of fractions, they search for connections to existing knowledge. Procedures from the whole number domain are tried, but many do not work on the new numbers! Recent research has focused on the unit as a way to link whole number and rational number understanding (Behr, Harel, Post & Lesh, 1992). Studies have suggested that students intuitively form units (Lamon, 1994), and that this intuitive knowledge can serve as a foundation for rational number understanding (Lamon, 1994; Mack, 1990). Golding (1994) …

Optimization And Scale-Up Of Thiarubrine A Production From Hairy Root Cultures Of Ambrosia Artemisiifolia., Santosh G. Bhagwath
LSU Historical Dissertations and Theses
Thiarubrine A (TA), a plant secondary metabolite synthesized by members of the family Asteraceae possesses antifungal and antiviral properties and is a potential pharmaceutical. The objective of the work was the optimization and scale-up of a bioprocess for the production of TA using hairy root cultures of Ambrosia artemisiifolia. At the inception of the work an established hairy root culture of the model system was used as inoculum in reactor experiments for the development of a protocol for the quantification of TA and in subsequent shake flask experiments to determine optimum culture conditions. TA accumulation closely paralleled growth and then …

An Integrated Gps-Gis Methodology For Performing Travel Time Studies., Cesar A. Quiroga
LSU Historical Dissertations and Theses
This dissertation describes a methodology for conducting travel time studies based on global positioning system (GPS) receivers and geographic information system (GIS) technology. Compared to traditional approaches, the new methodology provides consistency, automation, finer levels of resolution, and better accuracy in measuring travel time and speed. These characteristics enable the detection of localized traffic effects much more efficiently than with traditional techniques. The new methodology automates the data collection and data reduction procedures, and provides improved procedures for documenting and analyzing travel time and speed data. As a result, large amounts of reliable travel time and speed data can be …
Weak Convergence Of Interacting Stochastic Systems., George William Paslaski
Weak Convergence Of Interacting Stochastic Systems., George William Paslaski
LSU Historical Dissertations and Theses
The aim of the dissertation is to establish the weak convergence of mean-field interacting particle systems driven by Poisson random measures and semimartingales. The limit of the stochastic systems is identified by the use of martingale problems and Picard iteration schemes. The interacting systems driven by Poisson random measures are shown to be stable with respect to the coefficients of the system as well as the driving terms. The same results can be achieved when a random interaction term independent of the driving terms is introduced into the coefficients of the system. Equations driven by semimartingales do not neccesarily possess …
Linear Matrix Inequality Approach To Robust Emergency Lateral Control Of A Highway Vehicle With Time-Varying Uncertainties., Robert Edward Benton Jr
Linear Matrix Inequality Approach To Robust Emergency Lateral Control Of A Highway Vehicle With Time-Varying Uncertainties., Robert Edward Benton Jr
LSU Historical Dissertations and Theses
New linear-matrix-inequality (LMI) based methods are developed for the static-output-feedback stabilization and reduced-gain static-output-feedback stabilization of time-invariant systems. Unlike previous methods, the static-output-feedback method is non-iterative in LMI solutions. The methods are extended to design robust static-output-feedback controllers for time-varying systems using a polytopic-systems approach. Examples are given which demonstrate the use of each of the new methods. The specific problem of emergency lateral control of a highway vehicle is then addressed using the new robust static-output-feedback method. A controller is designed which robustly stabilizes the vehicle over the range of highway speeds (15 to 30 m/s) and a range …
Land/Water Interface Delineation Using Neural Networks., Rajabhushanam Cherukuri
Land/Water Interface Delineation Using Neural Networks., Rajabhushanam Cherukuri
LSU Historical Dissertations and Theses
The rapid decline in acreage of land areas in wetlands caused by frequent inundations and flooding has brought about an increased awareness and emphasis on the identification and inventory of land and water areas. This dissertation evaluates three classification methods--Normalized Difference Vegetation Index technique, Artificial Neural Networks, and Maximum-Likelihood classifier for the delineation of land/water interface conditions using Landsat-TM imagery. The effects of three scaling algorithms, including resampling by aggregation, Gaussian smoothing, and local variance analysis, on the classification accuracy are analyzed to determine how the delineation, quantification and analysis of land/water boundaries relate to problems of mixed pixels, scale …
Coupled Field Equations For Saturated Soils And Its Application To Piezocone Penetration And Shield Tunneling., Murad Yusuf Abu-Farsakh
Coupled Field Equations For Saturated Soils And Its Application To Piezocone Penetration And Shield Tunneling., Murad Yusuf Abu-Farsakh
LSU Historical Dissertations and Theses
An elasto-plastic coupled system of equations are formulated here in order to describe the time-dependent deformation of saturated cohesive soils. Formulation of these equations is based on the principle of virtual work and the theory of mixtures for inelastic porous media as proposed by Prevost (1980) and Kiousis and Voyiadjis (1988). The saturated soil is considered as a mixture consisting of two deformable media, the solid grains and the water. Each medium is regarded as a continuum and follows its own motion. The coupled equations are developed for large deformations with finite strains in an updated Lagrangian reference frame. The …
The Rainbow Portrait And The Faery Queen: Emblem, Imagination And The Arthurian Gentleman., Robert Gibson Robinson Iii
The Rainbow Portrait And The Faery Queen: Emblem, Imagination And The Arthurian Gentleman., Robert Gibson Robinson Iii
LSU Historical Dissertations and Theses
This work re-interprets the symbolism of the emblematic "Rainbow" portrait (c. 1600) of Elizabeth I. The traditional title comes from the identification of the rainbow in the portrait as that of Genesis 9:13. In fact, this work demonstrates, it is the philosophers' rainbow, a cryptonym for the colors--black, red, white--of the three stages of alchemic transmutation: purification, illumination, perfection. Elizabeth is represented as the Faery Queen, the alchemical monarch--historically the pre-Homeric Hecate--who transmutes not only the brazen world of her subjects but their brassy selves as well. In the text the portrait is therefore designated the "Alchemists' Rainbow" portrait, the …
Technical Training Program Evaluation: Present Practices In United States' Business And Industry., Skip Twitchell
Technical Training Program Evaluation: Present Practices In United States' Business And Industry., Skip Twitchell
LSU Historical Dissertations and Theses
There is a lack of information on training evaluation. For those studies addressing the amount of evaluation that occurs and in which samples can be identified, the samples are non-random. There have been very few reports on the methods used for evaluation or the reasons why there is so little evaluation. This study used a random sample selected from members of the ASTD professional practice area titled, Technical and Skills Trainers. It can be argued that this is an informed sample involved in a training area that produces objective outcomes and should produce a favorable picture of training evaluation. Questions …
The Composition Of Politics: Creativity In The Political Thought Of Simone Weil And Albert Camus., John Randolph Leblanc
The Composition Of Politics: Creativity In The Political Thought Of Simone Weil And Albert Camus., John Randolph Leblanc
LSU Historical Dissertations and Theses
This essay traces the critical development of the idea of creativity through the intellectual relationship of Simone Weil and Albert Camus. Members of the French Resistance during the Second World War, Camus and Weil never met. Camus became enamored of her work after her death and is largely responsible for its publication. Camus recognized in Weil a markedly distinct, but kindred, spirit. Despite the apparent conflict between her Christian mysticism and his existential orientation, they both sought the preservation of the specifically human in a world which, in valuing a mechanistic form of reason, tended to objectify the human. Their …
Feedback Linearizing Control Strategies For Chemical Engineering Applications., Michael James Kurtz
Feedback Linearizing Control Strategies For Chemical Engineering Applications., Michael James Kurtz
LSU Historical Dissertations and Theses
Two widely studied control techniques which compensate for process nonlinearities are feedback linearization (FBL) and nonlinear model predictive control (NMPC). Feedback linearization has a low computational requirement but provides no means to explicitly handle constraints which are important in the chemical process industry. Nonlinear model predictive control provides explicit constraint compensation but only at the expense of high computational requirements. Both techniques suffer from the need for full-state feedback and may have high sensitivities to disturbances. The main work of this dissertation is to eliminate some of the disadvantages associated with FBL techniques. The computation time associated with solving a …
Toward Prescriptive Alternatives To Secondary School Suspensions: Risk Analysis Using An Epidemiologic Approach., Cynthia P. Morgan-D'Atrio
Toward Prescriptive Alternatives To Secondary School Suspensions: Risk Analysis Using An Epidemiologic Approach., Cynthia P. Morgan-D'Atrio
LSU Historical Dissertations and Theses
Data were collected from a large urban high school in order to investigate the characteristics of students who get suspended. Descriptive, epidemiologic analyses, and multivariate statistical analyses were used to investigate which, if any of several screening variables were most likely to predict secondary school suspensions for 9th grade students. Because multivariate statistics may be tedious for many to interpret, epidemiologic analyses were used in order to more easily disseminate study findings to readers and those within the school setting. For males, statistics were calculated for three groups of students: (1) males having more than one 9th grade suspension, (2) …

An Invariance Property Of Common Statistical Tests, N. Rao Chaganty, A. K. Vaish
Mathematics & Statistics Faculty Publications
Let A be a symmetric matrix and B be a nonnegative definite (nnd) matrix. We obtain a characterization of the class of nnd solutions Σ for the matrix equation AΣA = B. We then use the characterization to obtain all possible covariance structures under which the distributions of many common test statistics remain invariant, that is, the distributions remain the same except for a scale factor. Applications include a complete characterization of covariance structures such that the chisquaredness and independence of quadratic forms in ANOVA problems is preserved. The basic matrix theoretic theorem itself is useful in other characterizing …
