Promoting Science Teacher Education Through Dissonance And Discrepancy, Nelofer Halai, Alan E. Wheeler

Institute for Educational Development, Karachi

While inquiry in science teaching has found a great deal of acceptance (Colletet and Chiapetta, 1989), there is a growing recognition that educators need a wider repertoire of inquiry strategies applicable to various situations. One promising approach is through the use of so-called ‘dissonant’ or ‘discrepant events’. This concept of discrepancy can be traced to the early work of Festinger (1975) and his Theory of Cognitive Dissonance in which he stated that the creation of dissonance is psychologically very uncomfortable and motivates individuals to actively reduce the level of dissonance and thereby return to a state of greater equilibrium or …

Linear Programming, Mendu Rammohan Rao, V Chandru

Working Papers

Linear programming has been a fundamental topic in the development of the computational sciences. The subject has its origins in the early work of L.B.J. Fourier on solving systems of linear inequalities, dating back to the 1820's. More recently, a healthy competition between the simplex and interior point methods has led to rapid improvements in the technologies of linear programming. This combined with remarkable advances in computing hardware and software have brought linear programming tools to the desktop, in a variety of application software for decision support. Linear programming has provided a fertile ground for the development of various algorithmic …

The Effect Of Ink Jet Coating Rheology On Screening, Burak Aksoy

Masters Theses

Ink jet coating formulations are becoming of increasing importance due to rapid expansion in digital printing. These coatings have very specific ink absorption requirements, which are fulfilled by using polyvinyl alcohol and silica as binder and pigment, respectively. These coatings have unique rheological behavior and often have problems in industry during the filtering process. In this work, an attempt was made to relate filter blocking to the rheological behavior of the coating. A series of coatings were prepared and their rheological properties characterized. The solids content and pigment selection of the coating were altered in order to adjust the coating …

De-Platonizing And Democratizing Education As The Bases Of Service Learning, Ira Harkavy, Lee Benson

Service Learning, General

The theoretical bases of academic service learning are examined, with particular attention to John Dewey’s contributions. The service learning movement is conceptualized as part of an ongoing—and still unsuccessful—effort to “de-Platonize” and democratize American higher education in particular and American schooling in general.

Measurement Of The Branching Fractions Of ΛC+→Pk̅N (Π), M. S. Alam, Kenneth A. Bloom, Cleo Collaboration

Kenneth Bloom Publications

Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon Λ_c⁺ into pK^-π⁺π⁰, pK⁰, pK⁰π⁺π^-, and pK⁰π⁰, all measured relative to pK^-π⁺. The relative branching fractions are 0.67±0.04±0.11,0.46±0.02±0.04,0.52±0.04±0.05, and 0.66±0.05±0.07, respectively.

Hermite–Sinusoidal-Gaussian Beams In Complex Optical Systems, Lee W. Casperson, Anthony A. Tovar

Electrical and Computer Engineering Faculty Publications and Presentations

Sinusoidal-Gaussian beams have recently been obtained as exact solutions of the paraxial wave equation for propagation in complex optical systems. Another useful set of beam solutions for Cartesian coordinate systems is based on Hermite–Gaussian functions. A generalization of these solution sets is developed here. The new solutions are referred to as Hermite–sinusoidal-Gaussian beams, because they are in the form of a product of Hermite-polynomial functions of either complex or real argument, sinusoidal functions of complex argument, and Gaussian functions of complex argument. These beams are valid for propagation through systems that can be represented in terms of complex beam matrices, …

Vertical Resistivity Electrode Arrays For Detecting Hydrocarbon Movement And Content In Sands, Kirt Elliott

Masters Theses

In many contamination sites where hydrocarbon is involved an accurate thickness of the contaminant can not be achieved through the most commonly used methods. The purpose of this study is to find an alternate method of determining a precise thickness and monitor the contaminant movement in conjunction with the current methods. Vertical resistivity electrode arrays were tested in a lab environment on singular probes and between probes. The arrays tested were the Wenner, dipole dipole, gradient, parallel and down-hole 3-arrays. Electrode pipes were constructed and placed into a sand tank where the hydrocarbon thickness and the water level could be …

Analysis And Testing Of Plates With Piezoelectric Sensors And Actuators, Jeffrey S. Bevan

Mechanical & Aerospace Engineering Faculty Publications

Piezoelectric material inherently possesses coupling between electrostatics and structural dynamics. Utilizing linear piezoelectric theory results in an intrinsically coupled pair of piezoelectric constitutive equations. One equation describes the direct piezoelectric effect where strains produce an electric field and the other describes the converse effect where an applied electrical field produces strain. The purpose of this study is to compare finite element analysis and experiments of a thin plate with bonded piezoelectric material. Since an isotropic plate in combination with a thin piezoelectric layer constitutes a special case of a laminated composite, the classical laminated plate theory is used in the …

(A Note On)(2) The Shape Of The Erythrocyte, J. A. Adam

Mathematics & Statistics Faculty Publications

A note on the shape of the red blood cell is revisited, utilizing variational calculus to to find an extremum for the surface area of such a cell, using the volume as a constraint. A fairly significant error in the value of the volume is corrected, and the note concludes with a discussion of measures of cell shape (such as the sphericity index) which are more appropriate than the dimensional surface area to volume ratio.

Part III explores the effects that electronic cash can have on money laundering. Part IV explains through a series of hypotheticals how "cyberlaundering" can occur. Part V analyzes the federal government's response to the threat of money laundering with electronic cash. Part VI concludes the Article with suggestions.

Administrator And Teacher Perceptions Of The Inclusion Of Students With Learning Disabilities In Regular Education Classrooms In Nebraska, Linda S. Wanzenried

Student Work

This study investigates the perceptions of principals, and regular and special education teachers working in public elementary schools in Nebraska relative to the inclusion of students with learning disabilities in regular education classrooms. An Inclusion Perceptions Survey, developed for this research, was mailed to 50 principals, 75 special educators, and 546 regular educators, a randomly selected sample representing approximately 5% of the Nebraska populations of these professional groups. The overall response rate was 47%, yielding 318 surveys for analysis. Results demonstrated statistically significant differences in the perceptions of principals and regular educators and of special educators and regular educators with …

Why Are We Here? What Are We Doing? Interdisciplinary Social Studies For The 21st Century, Ann L. Rappaport

School K-12

It's the interdisciplinary potential that drew many of us into social studies from the start, isn't it? Because the human condition is, in fact, interdisciplinary. We're attracted by the study of real people and their challenges. We're magnetized by the processes people use to find solutions to a variety of societal problems. It's appealing to learn how people organize to accomplish certain goals. We thrive on diversity, on relationships, on cultural artifacts, on connections. We love the drama of discovery.
