Shaking It Up: Challenging Veteran Teachers To Change, Evelyn Baker Lang

Educational Studies Dissertations

My research, conducted at a 600 student middle school, explored the conditions and factors needed by veteran teachers to learn about and implement educational change, either mandated or teacher-initiated. Qualitative research methods used included in-depth interviews of veteran teachers and observations in classrooms, cluster meetings and professional development workshops. Five factors appeared to facilitate the change effort for this group of teachers. They are: An understanding that the change process is a challenge in itself. A school culture that is conducive to change. A school principal who supports, inspires and encourages teachers. Appropriate professional development is offered to teachers. Teachers …

What Archetypes Of Representation Do Children Between The Ages Of Four And Seven Employ When Creating Route Maps Of Familiar Interior Spaces?, Christine G. Price

Educational Studies Dissertations

This study investigated the symbols of representation young children choose to incorporate when they draw route maps of familiar interior spaces, based on the premise that development of map-making skills might unfold in much the same stage-like manner as the development of the ability to draw the human figure. In this investigation, children between the ages of 4 and 7 enrolled in a small independent elementary school were each asked to draw a map showing the route a person unfamiliar to the school would take to travel from the child's classroom to the school gymnasium. Strategies during map-making were noted; …

Comparison Of The Theoretical And Experimental Band Structure Of Poly (Vinylidene Fluoride) Crystal, Chun-Gang Duan, Wai-Ning Mei, John R. Hardy, Stephen Ducharme, Jaewu Choi, Peter A. Dowben

Physics Faculty Publications

The electronic structure and band symmetries of the ferroelectric phase of poly (vinylidene fluoride) (PVDF) are studied by using the first-principles density-functional method. Our calculated results agree well with the angle-resolved photoemission experiments. We find that the PVDF crystal has an energy gap of about 6 eV at the Γ-point. Large dispersion of the valence band is found only along the chain direction, which is consistent with the quasi-one-dimensional nature of PVDF. In particular, the band symmetries of the valence states deduced theoretically are in good agreement with experiment. Finally, further investigations on the electronic structure of poly(trifluoroethylene) (PTrFE) …

Spectral Functions Of The Falicov-Kimball Model With Electronic Ferroelectricity, Wei-Guo Yin, Wai-Ning Mei, Chun-Gang Duan, Hai-Qing Lin, John R. Hardy

Physics Faculty Publications

We calculate the angular resolved photoemission spectrum of the Falicov-Kimball model with electronic ferroelectricity where d- and f-electrons have different hoppings. In mix-valence regimes, the presence of strong scattering processes between d – f excitons and a hole, created by emission of an electron, leads to the formation of pseudospin polarons and novel electronic structures with bandwidth scaling with that of d – f excitons. Especially, in the two-dimensional case, we find that flat regions exist near the bottom of the quasiparticle band in a wide range of the d- and f-level energy difference.

Goal-Converging Behavior Networks And Self-Solving Planning Domains, Bernhard Nebel, Yuliya Lierler

Computer Science Faculty Proceedings & Presentations

Agents operating in the real world have to deal with a constantly changing and only partially predictable environment and are nevertheless expected to choose reasonable actions quickly. One way to address this problem is to use behavior networks as proposed by Maes, which support real-time decision making. Robotic soccer appears to be one domain where behavior networks have been proven to be particularly successful. In this paper, we analyze the reason for the success by identifying conditions that make behavior networks goal converging, i.e., allow them to reach the goals regardless of which particular action selection scheme is used. In …

Computing Answer Sets Of A Logic Program Via-Enumeration Of Sat Certificates, Yuliya Lierler, Marco Maratea

Computer Science Faculty Proceedings & Presentations

Answer set programming is a new programming paradigm proposed based on the answer set semantics of Prolog. It is well known that an answer set for a logic program is also a model of the program's completion. The converse is true when the logic program is "tight". Lin and Zhao showed that for non-tight programs the models of completion which do not correspond to answer sets can be eliminated by adding to the completion what they called "loop formulas". Nevertheless, their solver ASSAT 1 has some disadvantages: it can work only with basic rules, and it can compute only one …

The Impact Of Service Learning On Perceptions Of Self-Efficacy, Monalisa Mccurry Mullins

Thesis, Dissertations, Student Creative Activity, and Scholarship

In recent years, the role of higher education in promoting volunteerism and social responsibility through service learning has become an issue that may radically impact both faculty and student development programs on American college campuses. Despite the significant amount of data regarding the impact of student participation in service learning on students' attitudes toward volunteerism and social responsibility, there is still a tremendous gap in our understanding of how such participation impacts subsequent student perceptions of personal self-efficacy. The purpose of this qualitative case study is to further articulate and clarify the relationship between student involvement in service learning courses …

Cesar Chavez: Who Are Today's Heroes?, Rmc Research Corporation, Cesar Chavez Foundation

Curriculum

This project will help young people to understand the characteristics that make individuals “heroes.” In learning about César E. Chávez’s life and values, students will learn about history, self determination, help for the needy, and actions that promote equity and justice. They will develop a sense of what it means to contribute to society and how they may make a difference. Students will also identify ways in which they can incorporate these characteristics into their own lives and recognize heroes in their community. Participation in the Chávez inspired service-learning project will promote academic learning, civic responsibility, and personal/social development.

Sundials And Their Shady Past, Elliott Ostler, Neal Grandgenett

Teacher Education Faculty Publications

Throughout history, patterned approaches to determining and subdividing time have been considered among the greatest natural mathematical connections ever conceived by mankind. Over the years, this mathematical quest for time has certainly been shrouded in utility (as evidenced by atomic clocks that are accurate to within trillionths of a second by using the mathematically predictable resonance frequencies of elements such as Cesium), but the more romantic and aesthetic virtues of historical time pieces lie in the interplay between pure mathematics and architectural beauty. Although the movement of celestial bodies relative to one another has acted as a basis for the …

Utilizing Structure Property Correlations To Predict And Analyze Two Derivatives Of An Ampicillin Homologous Series, C. Malesa, J. Stoddard, Ronald Bartzatt

Chemistry Faculty Publications

Structure Property Correlation methods such as regression analysis and pattern recognition are applied to predict the molecular properties of two members of an ampicillin homologous series. The pentyl and hexyl esters of ampicillin are also evaluated for their similarity to other penicillins by use of multiple regression, contingency tables, cluster analysis, correspondence analysis, self organizing tree algorithms, factor analysis, principal component analysis, box plots, and other graphing methods. Other members of the homologous series include methyl, ethyl, propyl, and butyl esters of ampicillin which have been previously synthesized and tested in tissue culture against Escherichia coli. All of the tested …

Introducing The Global Diffusion Of The Internet Series, Peter Wolcott, Seymour E. Goodman

Information Systems and Quantitative Analysis Faculty Publications

Many genes can play a role in multiple biological processes or molecular functions. Identifying multifunctional genes at the genome-wide level and studying their properties can shed light upon the complexity of molecular events that underpin cellular functioning, thereby leading to a better understanding of the functional landscape of the cell. However, to date, genome-wide analysis of multifunctional genes (and the proteins they encode) has been limited. Here we introduce a computational approach that uses known functional annotations to extract genes playing a role in at least two distinct biological processes. We leverage functional genomics data sets for three organisms—H. sapiens, …

Trace Analysis Of Organic Substances, Alan Giltinan

Theses

One of the major challenges facing the pharmaceutical industry is the control of the amount of trace contaminants during the manufacture of organic substances. Lowering the level of contamination improves the quality of the product and reduces possible side effects.

One of the main techniques used to detect trace contaminants is UV-VIS spectroscopy, where the unique absorption fingerprint of a chemical reveals its presence. UV-VIS absorption is based upon the Beer-Lambert Law. The critical point to note about this law is that the absorption is exponentially dependent on both the concentration of the absorber and the pathlength traversed by the …

Studies On The Opto-Electronic Constants Of Alkali-Halide Crystals, Mahmoud A. Salem

Turkish Journal of Physics

In this presentation, the correlation between refractive index n of alkali-halide crystals and both energy band gap E_{g} and Pauling's electronegativity difference \Delta x have been studied. The following relations are proposed for estimating the refractive index n: n^2 + C = A / E_{g} ^{1 / 2} and n^2 + C = E / (\Delta x)^{0.425}, where A, C and E are numerical constants. In addition, an interrelation between the energy band gap E_{g} and electronegativity difference \Delta x has been also proposed. The proposed relation is E_g = 4.45 (\Delta x)^{0.85}. The estimated values of the refractive index …
