Educational Assessment As Invitation For Dialogue, Ronald C. Arnett, Pat Arneson Jan 1997

Educational Assessment As Invitation For Dialogue, Ronald C. Arnett, Pat Arneson

Journal of the Association for Communication Administration

This article offers a communicative foundation for viewing the act of educational assessment as an opportunity for dialogue with a larger public in the U.S. There are three main areas which comprise an invitation for dialogue with the public: the politics of assessment, foundation for dialogue about the communication discipline and the proposal for a dialogic communication with the public as a way to create shared meaning about the process of communication. Invitation to dialogue envisions communication as socially constructed. Both self and other are central to the emergence of truth. The wise communicator is careful, but in the midst …


National Preferences In Business And Communication Education: A Survey Update, Jerry L. Winsor, Dan B. Curtis, Ronald D. Stephens Jan 1997

National Preferences In Business And Communication Education: A Survey Update, Jerry L. Winsor, Dan B. Curtis, Ronald D. Stephens

Journal of the Association for Communication Administration

This article discusses the results of a survey in the U.S. regarding national preferences in business and communication education. From the results of this and the previous study, it appears that the skills most valued in the contemporary job-entry market are communication skills. The skills of listening, oral communication (both interpersonal and public), written communication and the trait of enthusiasm are indicated to be the most important. Again, it would appear to follow that university officials wishing to be of the greatest help to their graduates in finding employment would make sure that basic competencies in oral and written communication …


Continuum Limit Of Lattice Approximation Schemes, Carl M. Bender, Alexander Tovbis Jan 1997

Continuum Limit Of Lattice Approximation Schemes, Carl M. Bender, Alexander Tovbis

Faculty Bibliography 1990s

Boundary-layer perturbation theory problems are inherently singular. However, it is known that discretizing the problem by introducing a lattice may convert such problems into regular perturbation problems. The singular nature of boundary-layer problems is then relegated to and hidden in the continuum limit, the subtle limit in which the lattice spacing tends to zero. If the lattice is introduced cavalierly, then extrapolating to zero lattice spacing gives a sequence of extrapolants that at first approaches the correct limit and then veers off, thereby revealing the asymptotic nature of such problems. However, discretizing the problem following the procedures described here yields …

Transform Coding Of Signals Using Approximate Trigonometric Expansions, Qurban A. Memon, Takis Kasparis Jan 1997

Transform Coding Of Signals Using Approximate Trigonometric Expansions, Qurban A. Memon, Takis Kasparis

Faculty Bibliography 1990s

For signal representation it is always preferred that a signal be represented using a minimum number of parameters. in any transform coding scheme, the central operation is the reduction of correlation and thereby with appropriate coding of the transform coefficients, allows data compression to be achieved. The objective of data encoding is to transform a data array into a statistically uncorrelated set. This step is typically considered a "decorrelation" step, because in the case of unitary transformations the resulting transform coefficients are relatively uncorrelated. Most unitary transforms have the tendency to compact the signal energy into relatively few coefficients. The …


An Approach To The Synthesis Of Biological Tissue, Jannick P. Rolland, Robin N. Strickland Jan 1997

An Approach To The Synthesis Of Biological Tissue, Jannick P. Rolland, Robin N. Strickland

Faculty Bibliography 1990s

Mathematical phantoms developed to synthesize realistic complex backgrounds such as those obtained when imaging biological tissue, play a key role in the quantitative assessment of image quality for medical and biomedical imaging. We present a modeling framework for the synthesis of realistic tissue samples. The technique is demonstrated using radiological breast tissue. The model employs a two-component image decomposition consisting of a slowly, spatially varying mean-background and a residual texture image. Each component is synthesized independently. The approach and results presented here constitute an important step towards developing methods for the quantitative assessment of image quality in medical and biomedical …


Transfer Of Momentum And Torque From A Light Beam To A Liquid, A. Yu. Savchenko, N. V. Tabiryan, B. Ya. Zel'dovich Jan 1997

Transfer Of Momentum And Torque From A Light Beam To A Liquid, A. Yu. Savchenko, N. V. Tabiryan, B. Ya. Zel'dovich

Faculty Bibliography 1990s

Refraction or absorption of light results in the force and torque, i.e., transfer of momentum and angular momentum from light to the medium. In transversely inhomogeneous beams, the force per unit volume f may have curlf not equal 0 leading to flow or to nonthermal and nongravitational convection in liquids. The force and the torque in scattering systems are as strong as in absorbing materials and may allow one to carry out experiments avoiding thermal effects. Nonlinear optical response of liquid crystals due to this convection is discussed.


Dynamics Of Low-Dimensional Dipolar Systems, J. M. Sun, Weili Luo Jan 1997

Dynamics Of Low-Dimensional Dipolar Systems, J. M. Sun, Weili Luo

Faculty Bibliography 1990s

Time decays of low-dimensional magnetic dipoles with anisotropic energy barriers were studied theoretically. We found that the dynamic behaviors are interaction specific. For a chain with ferromagnetic coupling, a single mode dominates and the decay is essentially exponential. For antiferromagnetic coupling, the dynamics can be characterized by two distinct groups of time scales. The spectrum results in a plateau in the decay of remanent magnetization. This novel behavior differs from the prediction of the mean-field theory. For a two-dimensional rectangular lattice, a transition between the bimodal decay and a quasilogarithmic decay occurs when the ratio of length to width varies.

Practical Considerations On Color Image Enhancement Using Homomorphic Filtering, Liviu I. Voicu, Harley R. Myler, Arthur R. Weeks

Faculty Bibliography 1990s

We present a study concerning the practical possibilities of using the homomorphic filtering for color image enhancement, Two of the most popular color models, RGB and C-Y (color difference), are employed and the results are comparatively discussed. The homomorphic filtering has proven to be a viable tool for both color models considered.


Mathematical Modeling Of Melting During Laser Materials Processing, J. Xie, A. Kar Jan 1997

Mathematical Modeling Of Melting During Laser Materials Processing, J. Xie, A. Kar

Faculty Bibliography 1990s

Melting is encountered in almost all laser materials processing. This article deals with a one-dimensional heat conduction problem to investigate the melting rate during laser materials processing. The problem is solved approximately to obtain a correlation among melt depth, power density, and laser irradiation time. Based on this correlation, the dynamics of melting, a relationship between the melt depth and power density and an average melting velocity are expressed by simple analytic formulas. These expressions are further simplified for high power densities (I greater than or equal to 10(9) W/m(2)). The times to reach the melting and boiling temperatures at …


Melting And Vaporization For Large-Area Film Removal With A Chemical Oxygen-Iodine Laser, J. Xie, A. Kar Jan 1997

Melting And Vaporization For Large-Area Film Removal With A Chemical Oxygen-Iodine Laser, J. Xie, A. Kar

Faculty Bibliography 1990s

Large-area film removal with lasers is a physical process of melting and vaporization of films. A mathematical model is developed to simulate the melting and vaporization of films under the irradiation of a chemical oxygen-iodine laser. The cross section of the film after laser scanning and the substrate surface temperature during laser irradiation are presented. There is an optimum laser power at which relatively wide films can be removed by maintaining low temperature at the substrate surface. The optimum laser power is associated with other process parameters. The results of film removal with TEM31 and TEM00 beams are compared, and …

The Link Between Established Psychological Type Preferences And Academic Achievement In Elementary School Students, Shelley Nacke Jan 1997

The Link Between Established Psychological Type Preferences And Academic Achievement In Elementary School Students, Shelley Nacke

Theses

Sixty-four third through eighth grade students from a rural parochial school were tested using the Murphy-Meisgeier Type Indicator for Children (MMTIC). Students were divided into three groups on the basis of the MMTIC scores: those showing no undetermined preferences, those showing one undetermined preference and those showing two or more undetermined preference. Grade point averages (GPA) were used to determine academic achievement for these students. Mean GP A scores for the three groups were compared using the t-test. Those students with two or more undetermined preferences showed significantly lower mean GP A scores than those students with no undetermined preferences.


Organizational And Social Systems, Ronald James Snelson Jan 1997

Organizational And Social Systems, Ronald James Snelson

Theses

This project explores systems theory and practice as applied to Communications. A system is an organized or complex whole; an assemblage or combination of things, or parts forming a complex or unitary whole. A system is made up of (1) inputs, (2) operations (or processes), (3) outputs. Each interacts with, and is dependent on the proper functioning of the other. If something happens to one part the others parts are affected. Thus, within an organization, what happens to one can affect the whole.

An organization is a system. The systems approach has three goals: ( 1) to define relationships both …

Following deregulation there were debates as to whether deregulation bad achieved its original goals . These debates have continued up until today.

The hypothesis stated herein was that research would indicate that airline deregulation had benefited the industry as a whole and that if further deregulation and more adherence to policies under deregulation were …


Incorporating Critical Thinking Skills Into The Language Arts Curriculum, Particularly In The Field Of Detective Fiction, Charles E. Bright Jan 1997

Incorporating Critical Thinking Skills Into The Language Arts Curriculum, Particularly In The Field Of Detective Fiction, Charles E. Bright

Theses

In this age of accelerated change and continuing complexity, there is a widely-recognized need to incorporate critical thinking skills into all aspects of everyday life and not simply as an optional philosophy class at the post-secondary level of American education.

Chapter One of this culminating project investigates the historical roots of critical thinking, with a brief investigation into the history of bow education in America (with slight digressions such as Alcott/Emerson's Temple School and John Dewey's Chicago experiments) has historically failed to foster the development of critical thinking skills in America's students by its centuries old tradition of emphasizing rote …

Diophantine Type Fractional Derivative Representation Of Structural Hysteresis, Part I: Formulation, Joe Padovan, Jerzy T. Sawicki Jan 1997

Diophantine Type Fractional Derivative Representation Of Structural Hysteresis, Part I: Formulation, Joe Padovan, Jerzy T. Sawicki

Mechanical Engineering Faculty Publications

Based on a diophantine representation of the operational powers, a fractional derivative modelling scheme is developed to simulate frequency dependent structural damping. The diophantine set of powers is established by employing the curvature properties of the defining empirical data set. These together with a remezed least square scheme are employed to construct a Chebyschev like optimal differintegro simulation. Based on the use of the rational form resulting from the diophantine representation, a composition rule is introduced to reduce the differintegro simulation to first order form. The associated eigenvalue/vector properties are then explored. To verify the robustness-stability accuracy of the overall …

Problem Construction And Creativity: The Role Of Ability, Cue Consistency, And Active Processing, Roni Reiter-Palmon, American Institutes For Research, Jennifer O'Connor Boes, Mark A. Runco Jan 1997

Problem Construction And Creativity: The Role Of Ability, Cue Consistency, And Active Processing, Roni Reiter-Palmon, American Institutes For Research, Jennifer O'Connor Boes, Mark A. Runco

Psychology Faculty Publications

Problem construction has been suggested as the first step in creative problem solving, but our understanding of the underlying process is limited. According to a model of problem construction (Mumford, Reiter-Palmon, & Redmond, 1994), problem construction ability, active engagement in problem construction, and the presence of diverse and inconsistent cues influence creative problem solving. To test these hypotheses, 195 undergraduates were asked to solve 6 real-life problems and complete a measure of problem construction ability. Active engagement in problem construction was manipulated by instructions to the participants. Cue consistency was manipulated by the information presented in the problem situation. The …

Correlation Of Changes In The Outer-Zone Relativistic-Electron Population With Upstream Solar Wind Measurements, J B. Blake, D N. Baker, Niescja E. Turner, K Ogilvie, R P. Lepping Jan 1997

Correlation Of Changes In The Outer-Zone Relativistic-Electron Population With Upstream Solar Wind Measurements, J B. Blake, D N. Baker, Niescja E. Turner, K Ogilvie, R P. Lepping

Physics and Astronomy Faculty Research

A study has been made of the correlation of the population of relativistic electrons in the outer-zone magnetosphere with the properties of the solar wind (speed, density, magnetic field) during a solar minimum period. The study is based upon observations made in the Spring of 1995 with sensors aboard 1994-026 and WIND. It is found that a large relativistic electron enhancement depends upon a substantial solar-wind speed increase associated with precursor solar-wind density enhancement, and, in particular, upon a southward turning of the interplanetary magnetic field
