Synthesis And Characterization Of Superparamagnetic Silica--Homopolypeptide Composite Particles, Sibel Turksen

LSU Doctoral Dissertations

Hierarchical construction and characterization of core-shell composite particles of interest are presented. The research described shows interest in new types of polymers that provide chirality and responsiveness which have been ignored for so long. The general synthetic design described in this document can be readily used as a model for other systems. Core-shell composite systems of interest consist of silica or silica-coated cobalt cores grafted with a homopolypeptide shell, mostly poly(epsilon-carbobenzyloxy-L-lysine) or poly(gamma-benzyl-L-glutamate). Core particles were decorated with amino groups through a silylation reaction. The amino groups initiated the polymerization (with attachment) of N-carboxyanhydride (NCA) monomers, resulting in a homopolypeptide …

Improving Analytical Writing Performance Of High School Freshman Social Studies Students Through Uniform Writing Standards, Kimberly Ann Juirdano

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to improve the analytical writing performance of freshman students in their social studies classes. The field of social studies requires students to review documents and respond argumentatively to questions posed by their teachers. The freshman social studies teachers in this applied dissertation profess that freshman students had poor writing skills, and therefore were unable to effectively analyze and argue in written form.

In order to remedy the problem of poor analytical writing skills, freshman social studies teachers implemented interventions such as (a) the development and usage of a locally-constructed common rubric, (b) writing laboratories in …

The Impact Of An Induction Program Within An Exceptional Educational Center To Assist Beginning Teachers, Donna A. Just

Abraham S. Fischler College of Education ETD Archive

This applied dissertation addressed the crisis of retaining beginning teachers at a public high school for exceptional students. The purpose of the project was to develop a program to support beginning teachers in their 1st year of teaching. A mentoring program within the school was developed based upon research and survey feedback. The program included (a) peer support, (b) administrative support, (c) positive role modeling, (d) professional development workshops, and (e) assistance in transitioning into a new career and setting.

To explore the critical needs of the beginning teachers at the school site, a survey was sent to all novice …

Asymmetry Of Above-Threshold Ionization Of Metal Clusters In Two-Color Laser Fields: A Time-Dependent Density-Functional Study, H. S. Nguyen, A. D. Bandrauk, Carsten A. Ullrich

Physics Faculty Research & Creative Works

A spherical jellium model and time-dependent density functional theory for two-color ultrashort laser pulses as a function of phase difference between two fields were used to calculate the above threshold ionization (ATI) spectra of small metal clusters. ATI spectra and the ionized electrons fluxes were obtained in the two opposite directions of the linearly polarized laser fields. It is found that ATI spectra has long energy plateaus, with cutoffs up to 30-40 times the ponderomotive energy Up. However, no extended plateaus were observed in high-harmonic generation spectra.

Development Of A Training Program For Postsecondary Allied Health Career School Practitioners, Evelyn Elliott Presley

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was developed to provide a training program for practitioners in postsecondary, for-profit allied health schools. The project was created to provide solutions to challenges that schools face when they hire individuals with technical work experience to teach adults. Too often, new hires are put in class without experience in teaching, an understanding of adult learners, and knowledge of the policies and procedures of the school.

The research questions that guided the developmental process were as follows:

1. What areas of concern currently exist in post-secondary, for-profit schools regarding the need for a training program for practitioners?

2. …
