3. Is the teenage group significantly better than the elementary school age group previously tested by Weiss (1973b)?

There were 50 normal-speaking subjects in the teenage group ranging in …

Infection Of Smallmouth Bass And Goldfish By Two Species Of Saprolegnia, Cheryl A. Mcginley

Dissertations and Theses

This study consisted of several experiments designed to compare the ability of two species of fungi, Saprolegnia ferax and S. parasitica to grow on two species of fish, smallmouth bass (Micropterus dolomieui) and goldfish (Carassius auratus), and to determine the criteria necessary for the development of these infections.

The results indicate that water in the fish tanks must be slightly acid (pH 6), warm (22°C), nonmoving, and that the fish must be wounded in order for fungal infection to occur. Cool water (18°C) and moving water, caused by aeration and filtration, are detrimental to fungal colony …

Differential Measurement Of A Language Concept Presented Via Video Tape Playback To First Grade Students, Richard Warren Trullinger

Dissertations and Theses

Educational television began in 1932 at the State University of Iowa. Until 1952, the potential of its contributions to education were not fully recognized. In 1952, however, the Federal Communication Commission created non-commercial television station. From that point in time, educational television has mushroomed.

This study tested the hypothesis: At least 80 percent of a given first grade population will respond accurately to the post-testing of a language concept, after the concept has been presented to them via a video tape playback using puppetry as the teaching method. In essence, the study was designed to determine whether or not an …

The answers to these two questions form the basis for this thesis. Color awareness as part of visual education and environmental sensitivity can be taught and should be taught in every educational institution. The key to BUCcessful instruction is informed, knowledgeable, color sensitive teachers and the exposure of students to workable color systems. Color …

Vibration Damping Characteristics Of Typical Harpsichord Strings, Jack Lee Simmons

Dissertations and Theses

Present-day builders of harpsichords disagree as to the use of iron or carbon-steel wire in their attempt to duplicate the tonal qualities of the early 16th century instruments. The variations in tone produced by vibrating iron and steel wires may be due, at least in part, to differences in their decay characteristics. A wire was set into vibration by placing a section in a magnetic field and passing a variable-frequency alternating current through it. A condition of resonance was established by appropriately selecting frequencies, lengths, and tensions that would simultaneously satisfy the relationship: fr = n/2L(T/p)1/2. Then measurements of decay …

The Politics Of Education -- An Analysis Of Selected Cases And Controversies In American Education, Lawrence Robert Stoffel

Dissertations and Theses

This study compiles a series of cases and controversies in American education, from the popularization of public education in the mid-1800's to the present, and then reviews them to determine scholarly political aspects, common themes, and trends. It then applies the identified themes to a model of “the school as a responsive political system” fashioned after David Easton's "Dynamic Response Model of a Political System” to demonstrate the operative nature of the themes.

The paper reviews the plight of Negro education in Alabama after the Civil War until 1901. It discusses accommodation in the realm of education as the United …

Interaction Patterns In The Campground, Dennis Lee Rockwood

Dissertations and Theses

The purpose of this project was to examine interaction patterns in various campground settings and to elaborate on camping literature which has suggested that the campground is a social event with high rates of interaction. In exploring this phenomenon, this report utilized observational techniques to document the temporal, spatial, familiarity, numerical, and behavioral dimensions of the observed interactions.

The data suggested that young adults and middle-aged persons were observed to be involved in, and initiated the highest proportions of, interactions. In general, males displayed far greater proportions of initiations than females. The highly developed campground exhibited higher proportions and rates …

A Study Of The Physiological Factors Affecting The Biological Conversion Of Arsenite To Arsenate, Shirley E. Phillips

Dissertations and Theses

Although arsenic is ubiquitous in the environment, certain forms of arsenic are added deliberately in ever increasing quantities. The addition of large quantities of the trivalent inorganic form (arsenite) could pose a serious hazard because of the toxicity of this form explicable in terms of its action of sulfhydryl containing enzymes and/or coenzymes. In the environment B.rsenite is rapidly converted to arsenate (the pentavalent inorganic form). Since a biological explanation for the oxidation of arsenite to arsenate was available only for cattle dips (a unique environment), this study was undertaken to examine sewage for the presence of arsenite oxidizing bacteria. …

Oregon And The Blue Eagle: A Study Of The Response Of Oregonians To The National Recovery Administration, John Craig Bledsoe

Dissertations and Theses

The original response of Americans to the National Recovery Administration (NRA) was almost unbounded enthusiasm in mid-1933. But the enthusiasm of the public, business and labor for the NRA noticeably declined by early 1934 and it continued to decline until the NRA was declared unconstitutional in May of 1935. The primary objective of this study is to determine whether the response of Oregon to the NRA followed that of the nation.

Focusing mainly upon the Portland metropolitan area, this study is based on information drawn from newspapers and other primary source materials available for the period during which the NRA …

Hot Electron Injection Into Dense Argon, Nitrogen, And Hydrogen, Pavel Smejtek, M. Silver, K. S. Dy, David G. Onn

Physics Faculty Publications and Presentations

Hot electrons have been injected into very dense argon, nitrogen, and hydrogen gases and liquids. The current‐voltage characteristics are experimentally determined for densities (N) of argon, nitrogen, and hydrogen ranging from about 10²⁰ to 10²² cm⁻³ and applied fields (E) ranging from about 10 to 10⁴ V cm⁻¹. The argon data show a square root E∕N dependence of the current. The nitrogen and hydrogen data show a complicated dependence of the current on E∕N due to the rapid thermalization in the region of the image potential of the injected electrons through inelastic collision processes not present in argon. A hydrodynamic‐two‐fluid …
