Academic Task Structures in High-Ability and Average-Ability Classes (open access)

Academic Task Structures in High-Ability and Average-Ability Classes

This study developed propositions concerning the nature of academic tasks as they are experienced in classrooms. Specifically, the purpose of this study was to analyze academic task structures in two language-arts classes, one designated as average-ability and one designated as high-ability. Few studies have concentrated on tasks as they are experienced in classrooms. While propositions concerning task systems are sparse in any curriculum area, language arts classes would seem to be particularly appropriate for supplying information about a wide range of task types. The present research thus described the nature of tasks in two junior high language arts classes.

Activity and Diffusion of Metals in Binary Aluminum Alloys (open access)

Activity and Diffusion of Metals in Binary Aluminum Alloys

To determine the activity of zinc in Zn-Al alloys, the electromotive force (emf) of the cell: Zn/ZnCl/sub 2/-KC1 (eut)/Zn,Al was measured at temperatures between 569.5 K (296.5C) and 649.5 K (376.5C). The applicability of a two-suffix Margules equation was demonstrated, in good agreement with theoretical expectations. The diffusion coefficient of Zn in Al determined from a planar diffusion model for the experimental data was about 3 x 10/sup -10/ cm/sup 2//sec to 2 x 10/sup -9/ cm/sup 2//sec in the range of temperature studied. This is higher than that found in the literature. The most plausible reason appears to be the high alumina concentration in the working electrode because of partial oxidation. Oxidation of the alloying metals was the primary cause of poor alloying between calcium/or zinc and aluminum, thereby frustrating similar measurements at a Ca-Al/or Zn-Al alloy. The literature on the activity of calcium and zinc is aluminum is reviewed.

An Application of Ridge Regression to Educational Research (open access)

An Application of Ridge Regression to Educational Research

Behavioral data are frequently plagued with highly intercorrelated variables. Collinearity is an indication of insufficient information in the model or in the data. It, therefore, contributes to the unreliability of the estimated coefficients. One result of collinearity is that regression weights derived in one sample may lead to poor prediction in another model. One technique which was developed to deal with highly intercorrelated independent variables is ridge regression. It was first proposed by Hoerl and Kennard in 1970 as a method which would allow the data analyst to both stabilize his estimates and improve upon his squared error loss. The problem of this study was the application of ridge regression in the analysis of data resulting from educational research.

A Beholding and Jubilant Soul: Spiritual Awakening in the Thought of Jonathan Edwards and Ralph Waldo Emerson (open access)

A Beholding and Jubilant Soul: Spiritual Awakening in the Thought of Jonathan Edwards and Ralph Waldo Emerson

This study explores continuities in thought between Jonathan Edwards and Ralph Waldo Emerson by comparing their respective views on spiritual awakening. Their parallel ideas are discussed as results of similar perceptual dispositions which lead both to view awakening as an inner metamorphosis that leaves man less self-centered and more capable of a universal perception and appreciation of spiritual unity and beauty. Emphasized are parallels in Edwards's and Emerson's concepts of God, their views on the nature of awakening, their versions of preparation, and their thoughts about virtue and the awakened man. These continuities are also discussed as ideas that compose an underlying unity in American thought which unites the seemingly contradictory heritages of Puritanism and transcendentalism.

Biofeedback Training: Avoidance Conditioning of Frontal EMG (open access)

Biofeedback Training: Avoidance Conditioning of Frontal EMG

The present study was designed to evaluate the efficacy of utilizing an avoidance conditioning paradigm in EMG biofeedback training and to compare this method to the standard biofeedback training paradigm. Frontalis EMG levels of 20 college students were monitored during non-stress and stress conditions. Half then received standard EMG biofeedback training. The other half received biofeedback with contingent aversive stimulation. Both groups received training to a relaxation criterion of 3 microvolts for 100 seconds or, for a maximum of two 20 minute sessions. Subjects were then monitored again during non-stress and stress conditions. Both groups obtained significant EMG reductions due to training with no significant differences between them. Standard biofeedback training required less time for subjects to achieve the relaxation criterion than did biofeedback with a shock-avoidance contingency. Possible applications of avoidance contingent biofeedback were suggested.

Bubble Dynamics at Gas-Evolving Electrodes (open access)

Bubble Dynamics at Gas-Evolving Electrodes

Nucleation of bubbles, their growth by diffusion of dissolved gas to the bubble surface and by coalescence, and their detachment from the electrode are all very fast phenomena; furthermore, electrolytically generated bubbles range in size from ten to a few hundred microns; therefore, magnification and high speed cinematography are required to observe bubbles and the phenomena of their growth on the electrode surface. Viewing the action from the front side (the surface on which the bubbles form) is complicated because the most important events occur close to the surface and are obscured by other bubbles passing between the camera and the electrode; therefore, oxygen was evolved on a transparent tin oxide "window" electrode and the events were viewed from the backside. The movies showed that coalescence of bubbles is very important for determining the size of bubbles and in the chain of transport processes; growth by diffusion and by coalescence proceeds in series and parallel; coalescing bubbles cause significant fluid motion close to the electrode; bubbles can leave and reattach; and bubbles evolve in a cycle of growth by diffusion and different modes of coalescence. An analytical solution for the primary potential and current distribution around a spherical bubble in …

A Cognitive-Behavioral Treatment Approach for Heterosocially Anxious Males (open access)

A Cognitive-Behavioral Treatment Approach for Heterosocially Anxious Males

The present study examined the efficacy of a cognitive-behavioral therapy package and a highly credible attention-placebo in the treatment of male heterosocial anxiety. Previous research provided evidence that cognitive factors are important in the etiology and maintenance of heterosocial anxiety, and suggested that a cognitive-behavioral approach should be effective in the treatment of this problem. Despite such evidence, relatively few therapy outcome studies have been conducted using cognitive-behavioral procedures.

A Collisional Mechanism in the Ion-Solid Interaction Which Enhances Scattering Yields Near 180⁰ (open access)

A Collisional Mechanism in the Ion-Solid Interaction Which Enhances Scattering Yields Near 180⁰

In the course of experiments using uniaxial double alignment channeling to investigate radiation damage in single crystals, an anomalously large ion-scattering yield from the near surface of disordered or simulated disordered solid targets was observed. The chronology of the discovery of this new ion-solid effect and its explanation are presented along with experiments detailing the dependence of the new effect upon ion type and energy, as well as target atomic number and density. Targets included a spectrum of polycrystalline elemental targets in a range Z = 29 to Z = 82. Also, the influence of the effect upon scattering yields from an aligned Au(110) single crystal is demonstrated.

Effect of nuclear spin on chemical reactions and internal molecular rotation (open access)

Effect of nuclear spin on chemical reactions and internal molecular rotation

Part I of this dissertation is a study of the magnetic isotope effect, and results are presented for the separation of /sup 13/C and /sup 12/C isotopes. Two models are included in the theoretical treatment of the effect. In the first model the spin states evolve quantum mechanically, and geminate recombination is calculated by numerically integrating the collision probability times the probability the radical pair is in a singlet state. In the second model the intersystem crossing is treated via first-order rate constants which are average values of the hyperfine couplings. Using these rate constants and hydrodynamic diffusion equations, an analytical solution, which accounts for all collisions, is obtained for the geminate recombination. The two reactions studied are photolysis of benzophenone and toluene and the photolytic decomposition of dibenzylketone (1,3-diphenyl-2-propanone). No magnetic isotope effect was observed in the benzophenone reaction. /sup 13/C enrichment was observed for the dibenzylketone reaction, and this enrichment was substantially enhanced at intermediate viscosities and low temperatures. Part II of this dissertation is a presentation of theory and results for the use of Zeeman spin-lattice relaxation as a probe of methyl group rotation in the solid state. Experimental results are presented for the time and angular …

An Empirical Investigation of the Potential Use of Data Required by FASB Statement No. 33 by Financial Analysts in the Dallas/Fort Worth and Houston Regions (open access)

An Empirical Investigation of the Potential Use of Data Required by FASB Statement No. 33 by Financial Analysts in the Dallas/Fort Worth and Houston Regions

In September, 1979, the Financial Accounting Standards Board issued FASB Statement No. 33, which required certain corporations to issue specified supplementary information based on constant dollars and current costs. This information is intended to show the impact of inflation on the reported earnings and capital of business enterprises. Opponents of Statement No. 33 claim that the required supplementary information is difficult to interpret and, therefore, will not be used. Proponents contend that the information is self-explanatory and would highlight the impact of inflation on the performance of business enterprises. Thus, they conclude the supplementary data will be useful to various user groups and will be used. This dissertation's primary objective was to determine whether the supplementary data will be used by financial analysts in the Dallas/Fort Worth and Houston regions in evaluating an enterprise's operating performance and its ability to maintain physical operating capability and the general purchasing power of financial capital.
