Comparison Of Students Enrolled In An Alternative Academic Program With Regularly Enrolled Students In A Research I University., Margo Myers Abadie Jan 1998

Comparison Of Students Enrolled In An Alternative Academic Program With Regularly Enrolled Students In A Research I University., Margo Myers Abadie

LSU Historical Dissertations and Theses

The purpose of this study was to describe an academic program, ACCESS, initiated to support entering freshmen students who did not meet the required admission standards for Louisiana State University in Baton Rouge. The ACCESS Program offered support in the areas of tutoring and special classes for the first 24 credit hours of study. The second part of the study was to compare academic and personal characteristics of ACCESS Students to a sample of Regularly Enrolled Freshmen Students to determine if differences existed between the two groups. Participants in the study were 244 ACCESS Students and 244 Regularly Enrolled Freshmen …

Granular Activated Carbon From Agricultural By-Products: Carbon Properties And Their Relationship To Sugar Decolorization Potential., Mohamed Ahmedna Jan 1998

Granular Activated Carbon From Agricultural By-Products: Carbon Properties And Their Relationship To Sugar Decolorization Potential., Mohamed Ahmedna

LSU Historical Dissertations and Theses

Representative samples of soft, low density, group 1 (rice straw, rice hulls, sugarcane bagasse) and hard, high density, group 2 agricultural by-products (pecan shells) were converted into granular activated carbons (GACs). Prior to pyrolysis, group 1 by-products were mixed with four binders, sugarcane molasses, sugar beet molasses, corn syrup and coal tar. GACs were produced from group 1 and 2 materials by physical activation (carbon dioxide, steam) or from group 2 materials by chemical activation (phosphoric acid). Carbons were evaluated for their physical (hardness, bulk density), chemical (ash, pH), surface (total surface area, pore size distribution, surface oxides) and adsorption …

An Analysis Of Factors Influencing The Teaching Of Biological Evolution In Louisiana Public Secondary Schools., Donald Wayne Aguillard Jan 1998

An Analysis Of Factors Influencing The Teaching Of Biological Evolution In Louisiana Public Secondary Schools., Donald Wayne Aguillard

LSU Historical Dissertations and Theses

Louisiana public school biology teachers were surveyed to investigate their attitudes toward biological evolution. A mixed method investigation was employed using a questionnaire and open-ended interviews. Results obtained from 64 percent of the sample receiving the questionnaire indicate that although teachers endorse the study of evolution as important, instructional time allocated to evolution is disproportionate with its status as a unifying concept of science. Two variables, number of college courses specifically devoted to evolution and number of semester credit hours in biology, produced a significant correlation with emphasis placed on evolution. The data suggest that teachers' knowledge base emerged as …

The Relationship Of Social Skills To Psychopathology For Individuals With Mild And Moderate Mental Retardation., Stephen Joseph Anderson Jan 1998

The Relationship Of Social Skills To Psychopathology For Individuals With Mild And Moderate Mental Retardation., Stephen Joseph Anderson

LSU Historical Dissertations and Theses

Recent advances in the field of mental retardation have included the development of instruments for assessment of both psychopathology and social skills in individuals with mental retardation. Researchers have subsequently begun investigating relationships between psychopathology and social skills in individuals with mental retardation. Initial studies have focused on persons with severe and profound mental retardation. The present study examined the relationship between psychopathology and social skills in individuals with mild and moderate mental retardation. This investigation used the Assessment for Dual Diagnosis (ADD) to measure psychopathology and the Social Performance Survey Schedule (SPSS) to evaluate social skills. Significant differences were …

Development Of A New Methodology For Particle Transport Calculations Utilizing Pointwise-Continuous Nuclear Data., Mehdi Asgari Jan 1998

Development Of A New Methodology For Particle Transport Calculations Utilizing Pointwise-Continuous Nuclear Data., Mehdi Asgari

LSU Historical Dissertations and Theses

The purpose of this study is to develop a new method to compute a continuous-energy representation of the neutron flux spectrum using the one-dimensional discrete ordinates method. The technique provides a rigorous calculational tool for applications that require a detailed description of the fine-structure variation in the space-dependent neutron energy spectrum over some energy ranges. This technique uses the combination of multigroup (MG) and rigorous pointwise (PW) solutions to the steady state Boltzmann transport equation in the calculations. Also utilized in this methodology are two new methods called "sub-moment" expansion and "cumulative integral" operator to accurately evaluate the Legendre moments …

Dynamics And Management Of Insecticide Resistance In The Horn Fly, Haematobia Irritans Irritans (L.) (Diptera: Muscidae)., Antonio Thadeu Medeiros De Barros Jan 1998

Dynamics And Management Of Insecticide Resistance In The Horn Fly, Haematobia Irritans Irritans (L.) (Diptera: Muscidae)., Antonio Thadeu Medeiros De Barros

LSU Historical Dissertations and Theses

Studies on resistance of the horn fly, Haematobia irritans irritans (L.), to insecticides were conducted in Louisiana from 1989 to 1998. These studies included monitoring resistance and resistance dynamics under different strategies of insecticide use, monitoring the efficacy of insecticide products, establishing a relationship between bioassay findings and product efficacy, and evaluation of a new insecticide class. In four years (1989--1992), efficacy of 20% diazinon-impregnated car tags used yearly was reduced from greater than twenty to just one week of control, and tag failure was observed with resistance ratios (RR) from 1.8 to 5.7. Diazinon resistance developed more slowly and …

M1 Strength Distributions In Deformed Nuclei., Thomas Georg Beuschel Jan 1998

M1 Strength Distributions In Deformed Nuclei., Thomas Georg Beuschel

LSU Historical Dissertations and Theses

The Elliott SU(3) Model, extended via pseudo-spin for heavy nuclei, is used to study low-lying magnetic dipole excitations in deformed nuclei which axe known as "scissors" modes. Proton and neutron degrees of freedom are handled explicitly and a system Hamiltonian that preserves SU(3) symmetry and one that includes single particle energies as well as quadrupole-quadrupole and pairing two-body interactions are considered. Starting from a basic nuclear Hamiltonian that preserves SU(3) symmetry, a microscopic interpretation of the "scissors" mode of the Two Rotor Model is realized through a linear mapping between invariants of the rotor group and SU(3). The model allows …

Directed Search In K-System Reconstruction., Christopher W. Branton Jan 1998

Directed Search In K-System Reconstruction., Christopher W. Branton

LSU Historical Dissertations and Theses

K-systems analysis is a factor analysis technique created through the generalization of key reconstructability analysis definitions and algorithms. The method is applied to functions on systems of discrete variables to discover a set of factors which can explain the bulk of the function's variation from the mean. K-systems analysis uses principles of information theory to reveal interactions which are often masked by the assumptions implicit in traditional methods. The method has been used successfully to analyze systems in several disciplines. Despite the success of k-systems analysis, obstacles to the creation of a mature methodology still exist. Some issues and open …

A Cross-Site Inquiry Into Reading Instruction In Differentially Successful Title I Schools., Gypsye Dugas Bryan Jan 1998

A Cross-Site Inquiry Into Reading Instruction In Differentially Successful Title I Schools., Gypsye Dugas Bryan

LSU Historical Dissertations and Theses

By design, elementary schools are places where students perform specified tasks and become literate. In practice, elementary schools enroll students who engage in instructional activity, yet many of these students fail to reach minimum literacy standards. This multiple-case qualitative inquiry focused on the inner workings of schools where students placed at risk learned to read and examined schools where similar students did not learn to read. Research conducted in four elementary schools addressed the following questions: (a) What resources, time factors, and management systems do elementary teachers use to create an effective reading environment? (b) How do reading assessment measures …
