The Activity Of Silicon Carbide Particles In Al-Based Metal Matrix Composites Revealed By Scanning Electrochemical Microscopy, David O. Wipf, L. Díaz-Ballote, L. Veleva, M. A. Pech-Canul, M. I. Pech-Canul

CAS Publications

Scanning electrochemical microscopy (SECM) is used to image variations in electrochemical activity over the surface of an aluminum-based metal matrix composite (MMC) in contact with buffered or unbuffered neutral solutions. The composite consists of an Al - 13.5% Si - 9% Mg alloy matrix and reinforcing silicon carbide particles (SiC_p). Feedback mode SECM imaging using ferrocenemethanol as a redox mediator in 0.1 M NaCl solution and in buffer solution (pH 6.8) revealed that the SiC particles are electrochemically active. The data suggest that the electronic conductivity at these sites is higher than that of the Al₂O …

William Stanley Hoole: Scholar-Librarian, John Jackson

Provenance, Journal of the Society of Georgia Archivists

When librarian William Stanley Hoole retired from the University of Alabama in 1973, he left a legacy of achievement worthy of consideration among librarianship's most capable pioneers. In twenty-nine years at the institution, Hoole improved the university's library service and holdings and won intellectual acclaim for the school through his numerous publications covering a wide range of topics. He addressed an organizational problem within the archival collection that resulted in the creation of a separate wing boasting his name today, the William Stanley Hoole Special Collections Library (WSHSCL). Capitalizing on the freedom of retirement, he moved from one stage of …

Piercing Gaze: Public Art In Schools, Laura Felleman Fattal

Journal of Social Theory in Art Education

A gaze is a silent facial gesture while a piercing gaze suggests a shrieking sound. Unpacking the word, silence, allows one to look at the difference between the verbalizations hailing empowerment and the actual functioning of reinstatements of purpose in learning, teaching and mentoring in a public school. Silence, in the following article, signals a discomfort, sometimes solitude and, at times, an abyss perhaps indicating the disparity between expectation and implementation. The depth of research necessary by the school community to reach consensus for names of dignitaries and the in-depth archival photographic research on the part of the professional artists …

Rocket Plume Particulate Characterization By Multiple Wavelength Opacity And Mie Scattering, Andrew P. Chouinard

Theses and Dissertations

In the presented work, experiments were conducted to assess the utility of plume opacity monitoring for hybrid rocket diagnostics. The first phase of the work involved measuring plume opacity at a single wavelength and then at two wavelengths simultaneously. Results showed excellent correlation between plume opacity and rocket motor firing cycle and correlation between plume opacity and oxidizer flow rate, thereby validating the utility of the technique. Additionally, a spectral dependence of plume opacity was demonstrated that indicated the possible presence of transparent particulates in the plume. Further phase 1 experiments investigated the performance requirements of a laser-based instrument to …

Attitudinal Changes That Occur As A Result Of High School Transition Classes, K. K. Bradshaw

Theses and Dissertations

The purpose of this study was to determine if high school transition classes alter student attitudes toward school, their peers, teachers/administrators or level of parental involvement. A large suburban high school class was administered a Likert Scale pre and posttest at the beginning of the course and at its conclusion. In addition to the pretest/posttest survey, students were grouped into six categories depending on their entering high school grade point averages. This delineation sought to ascertain if academic achievement either exacerbated or enhanced student perceptual indices on the survey. The data analyzed used an ANCOVA technique. Students were divided into …

Robotics Technologies For K-8 Educators: A Semiotic Approach For Instructional Design, Antoinette P. Bruciati

Education Faculty Publications

Robotics engineering courses have provided undergraduate computer science students with opportunities for designing and programming simulations of robotic tasks. In contrast, many teacher preparation programs have lacked courses in this area. Educators who have not gained a conceptual understanding of computer programming may not possess the skills that would have enabled them to successfully integrate robotics technologies into their K-8 curriculum.

Recent technological advances have provided a viable means of approaching this problem. Several icon-orientated robotics technologies have been identified that allow educators to master computer programming concepts through a simplified graphical user interface (GUI) design.

This investigation addressed the …

Pencils Of Quadratic Forms Over Finite Fields, Robert W. Fitzgerald, Joseph L. Yucas

Articles and Preprints

A formula for the number of common zeros of a non-degenerate pencil of quadratic forms is given. This is applied to pencils which count binary strings with an even number of 1's prescribed distances apart.

Multi-Variable Rankin-Selberg Integrals For Orthogonal Groups, David Ginzburg, Joseph Hundley

Articles and Preprints

We show a relation between a certain period and the existence of a simple pole for the spin and standard partial L functions corresponding to a generic cuspidal representation defined on the group GSO₈(A). We also relate these two conditions with the functorial lift from the exceptional group G₂ to GSO₈. The main new ingridient is a new multivariable Rankin-Selberg integral which represents the above two L functions.

The Linking Homomorphism Of One-Dimensional Minimal Sets, Alex Clark, Michael C. Sullivan

Articles and Preprints

We introduce a way of characterizing the linking of one-dimensional minimal sets in three-dimensional flows and carry out the characterization for some minimal sets within flows modeled by templates, with an emphasis on the linking of Denjoy continua. We also show that any aperiodic minimal subshift of minimal block growth has a suspension which is homeomorphic to a Denjoy continuum.

The Teacher Shortage: National Trends For Science And Mathematics Teachers, D. R. Sterling

Journal of Mathematics and Science: Collaborative Explorations

The shortage of science and mathematics teachers is a growing problem in the United States. This article looks at what research says about the causes for the growing teacher shortage and its effects on student achievement. As the teacher shortage worsens, teachers without a science or mathematics backgrounds are tasked to teach science and mathematics or underqualified teachers are being hired to fill the shortage. These underqualified teachers are not remaining in the profession, thus not solving the teacher shortage problem and creating an even higher turnover rate for teachers. In addition, experienced teachers are leaving the profession in greater …

The Impact Of Distance Learning On Faculty Contracts And Policies In Florida Community Colleges, M. Kate Legrand

CCAC Theses and Dissertations

Distance Learning is state of the art and is fast becoming a primary instructional delivery method in Florida community colleges. However, the present laws and policies that govern Florida's community college educational system are created based on traditional methods for delivering educational services. The potential change in faculty roles and responsibilities brought about by distance learning has raised questions about the impact distance learning will have on overall labor conditions for American faculty. In some instances, the use of alternative methods of delivering educational services has resulted in inconsistent policies. As more faculty become involved in teaching online courses, there …

Implementation Of An Individual Professional Development System Using A Web-Accessible Database, Edward R. Lovitt

CCAC Theses and Dissertations

Higher education is looking for ways to encourage new careers in education and retain current faculty working in the field. A successful working relationship between supervisors and faculty is crucial to continued attractiveness of a career in education. These shared relationships exist in "learning organization" models, which are used in professional development offerings that stress the importance of learning by individuals, as a way to benefit the entire institution.

This developmental study focused on building partnerships with supervisors and faculty. These partnerships require contracts or individual development plans that can be reviewed for progress and modified for future needs. The …
