Attention Deficit Hyperactivity Disorder In Adolescents And The Use Of Ritalin, Joanne Nelson

Theses and Dissertations

The purpose of this study was to see if a combined stimulant intervention/behavior improvement system facilitated greater gains on achievement tests and on a behavior improvement level system than a behavior improvement system alone with ADHD adolescents. The sample used consisted of 10 subjects classified with ADHD. Subjects were matched for IQ, age, educational classification and placement, socioeconomic status, and family type. Five subjects received stimulants and five received no medication, but all subjects were involved with the behavior improvement system at school. Pretest results were gathered using the KTEA (Kaufman Test of Educational Achievement, brief form) and the student's …

The Effects Of Cooperative Learning On Social Interactions And Attitudes Toward English Class In At-Risk Students, Catherine A. Mikionis

Theses and Dissertations

This research study examined the effects of cooperative learning methods on social interactions and attitudes toward English class in 18 at-risk high school students enrolled in a small alternative education program located on a college campus. The findings suggested cooperative learning methods increased students' positive social interactions, increased students' reported number of friends, and decreased students' cut classes. Although no significant difference in overall mean was found on the attitude toward English class survey, students' dislike for participating in class discussions decreased measurably. The implications for this study are such that cooperative learning methods can be effectively used with at-risk …

Neutral-Donor-Bound-Exciton Complexes In Zno Crystals, D. C. Reynolds, David C. Look, B. Jogai, C. W. Litton, T. C. Collins, W. C. Harsch, G. Cantwell

Physics Faculty Publications

Neutral-donor–bound-exciton transitions have been observed in ZnO. The isolated neutral donors are made up of defect pair complexes. The neutral-donor nature of these pair complexes was determined from magneticfield measurements and from two-electron transitions. Excited states of the neutral-donor bound excitons were observed in the form of rotator states analogous to rotational states of the H₂ molecule.

Discrete-To-Continuum Simulation Approach To Polymer Chain Systems: Subdiffusion, Segregation, And Chain Folding, Grace M. Foo, Ras B. Pandey

Faculty Publications

A discrete-to-continuum approach is introduced to study the static and dynamic properties of polymer chain systems with a bead-spring chain model in two dimensions. A finitely extensible nonlinear elastic potential is used for the bond between the consecutive beads with the Lennard-Jones (LJ) potential with smaller (R_c=2^1/6σ=0.95) and larger (R_c=2.5σ=2.1) values of the upper cutoff for the nonbonding interaction among the neighboring beads. We find that chains segregate at temperature T =1.0 with R_c=2.1 and remain desegregated with R_c=0.95. At low temperature (T=0.2), chains become folded, …

Kinetics Of Phase Transition In An Anticlinic Liquid Crystal Induced By A Uniform Temperature Field: Growth In One Dimension, X. Y. Wang, Jian-Feng Li, Eliezer Gurarie, S. Fan, Thein Kyu, S. S. Keast, Charles Rosenblatt

College of Polymer Science and Polymer Engineering

It is experimentally demonstrated that a transition from a synclinic to an anticlinic liquid crystal phase occurs via stable domain wall propagation after quenching in a uniform temperature field. Such a one-dimensional growth may be explained in terms of a nonlinear diffusion equation. The experiment provides the first example of free, one-dimensional growth in a system subjected to a pure and uniform temperature field.

In The Service Of Citizenship: A Study Of Student Involvement In Community Service, Robert A. Rhoads

Higher Education

I learn more through my volunteer work than I ever do in any of my classes at school. Talking to people from diverse backgrounds provides so much insight that people just can't imagine. I study all these different theories in political science and sociology, but until you get a chance to see how the social world influences people's everyday lives, it just doesn't have that much meaning.

I have been involved in volunteer work ever since I was in high school, and I'll probably continue to do stuff like Habitat [for Humanity] until I'm old and gray. I get a …

Implementation Of A Database System With Boolean Algebra Constraints, András Salamon

School of Computing: Dissertations, Theses, and Student Research

This thesis describes an implementation of a constraint database system with constraints over a Boolean Algebra of sets. The system allows within the input database as well as the queries equality, subset-equality and monotone inequality constraints between Boolean Algebra terms built up using the operators of union, intersection and complement. Hence the new system extends the earlier DISCO system, which only allowed equality and subset-equality constraints between Boolean algebra variables and constants. The new system allows Datalog with Boolean Algebra constraints as the query lan- guage. The implementation includes an extension of Naive and Semi-Naive evaluation methods for Datalog programs …

Design And Implementation Of Triveni: A Process-Algebraic Api For Threads + Events, Christopher P. Colby, Lalita Jategaonkar Jagaeesan, Radhakrishnan Jagadeesan, Konstantin Laufer, Carlos Puchol

Computer Science: Faculty Publications and Other Works

We describe Triveni, a framework and API for integrating threads and events. The design of Triveni is based on an algebra, including preemption combinators, of processes. Triveni is compatible with existing threads standards, such as Pthreads and Java threads, and with the event models structured on the Observer pattern. We describe the software architecture and algorithms underlying a concrete implementation of Triveni in Java. This environment includes specification based testing of safety properties. The results described in the paper have been used to integrate process-algebraic methods into (concurrent) object orientated programming.

Visualizing Uncertainty Of The Great Plains Boundary, Sonja Lynn Rossum

Department of Geography: Dissertations, Theses, and Student Research

Geographic regions all have some degree of uncertainty, though this is seldom represented on their maps. The Great Plains is an excellent example of how even a well known and widely accepted region can be a source of cartographic confusion. This region is fuzzy in nature, with few landforms or sharp changes in characteristics to help locate the boundary line. Also, the act ofregionalization itself is a highly subjective process, using defining criteria and methods of mapping selected by the cartographer.

The uncertainty of the Great Plains boundary location is shown by comparing many such interpretations from individual cartographers, all …

The New Aleph Silicon Vertex Detector, D. Creanza, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

The ALEPH collaboration, in view of the importance of effective vertex detection for the Higgs boson search at LEP 2, decided to upgrade the previous vertex detector. Main changes were an increased length (+/- 20 cm), a higher granularity for r phi view (50 mu m), a new preamplifier (MX7 rad hard chip), a polymide (upilex) fan-out on z side to carry the signals from the strips to the front-end electronics outside the fiducial region reducing consequently the passive material in the central region by a factor of two. The detector, the running experience and its performance will be described. …

Seminary Student Spiritual Formation: Recommendations Based On A Review Of Scripture And A Survey Of Evangelical Seminaries, William E. Wegert

Doctoral Dissertations and Projects

Concern for the spiritual formation in ministerial training has grown in recent years, and reasons for this are discussed. The history of spiritual formation in pastoral training as well as relevant Scriptures are reviewed. Particular attention is given to Christ's earthly ministry as well as key biblical terms related to spiritual formation. Certain expectations based on the weight of Scripture are determined. Results of a spiritual formation survey sent to thirty-five evangelical seminaries and a self-study of the writer's own seminary are analyzed. This project makes recommendations for enhancing seminary spiritual formation efforts.

High Mobility Algan/Gan Heterostructures Grown By Gas-Source Molecular Beam Epitaxy, L. K. Li, J. Alperin, W. I. Wang, David C. Look, Donald C. Reynolds

Physics Faculty Publications

We report on the growth of high electron mobility AlGaN/GaN heterostructures on sapphire substrates by gas-source molecular beam epitaxy (GSMBE) using ammonia as the nitrogen source. Improvements in structural, electrical, and optical properties of GaN and AlGaN layers have been made to achieve this goal. For the growth of AlGaN layers, the reflection high-energy electron diffraction revealed a twofold surface reconstruction, indicative of atomic smoothness of the film surface. High mobility two-dimensional electron gas has been achieved in both unintentionally doped (by piezoelectric effect induced by lattice mismatch strain) and modulation doped AlGaN/GaN heterostructures. The modulation-doped n+-Al_0.2Ga …

Impedance Of A Dipole Antenna In Ionospheric Plasma, Pavel Nikitin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Different approaches to evaluating the behavior of the impedance of an electrically short dipole antenna in the ionosphere as a function of the driving frequency are discussed. The induced EMF method in quasi-static approximation is chosen for evaluating the impedance and explained in great detail. The E-region of the ionosphere is considered and the cold collisional plasma model is used.

The influence of a density gradient in plasma on the impedance is explored, and the possible current distributions on the surface of the antenna are considered, including the current distribution for the antenna with a gap. The conclusions are drawn …

Separating Baroclinic Flow From Tidally Induced Flow In Estuaries, Chunyan Li, Arnoldo Valle-Levinson, Kuo Chuin Wong, Kamazima M. M. Lwiza

CCPO Publications

A simple method is used to separate the tidally induced and density-driven subtidal flows in a coastal plain estuary. This method is applicable to weak wind conditions and to systems with appreciable fortnightly variation of tidal amplitude. The baroclinic density-driven motion is assumed to depend on the river discharge, which generates a horizontal density gradient, and is weakened by vertical mixing, which in turn depends on tidal forcing. The barotropic tidally induced motion is assumed to be a function of the tidal amplitude. By Taylor series expansions, two equations are obtained. These equations show the dependence of the tidally induced …
