Life Drawing In The Secondary Classroom, Marilyn Jean Anderson

Dissertations and Theses

Life drawing presents some of the most difficult problems in the school art program: the difficulty of securing models, the necessity of using only the clothed model, and the resistance of many students to this particular discipline. The students' confidence in their own drawing abilities is at its nadir during early adolescence, and they become easily discouraged when faced with a live model as a subject. This thesis represents an effort to deal with these problems in a manner suited to the age and maturity level of the students. In order to build their self confidence, basic drawing skills and …

An Electromyographic Comparison Of Muscle Action Potentials Of Listeners Presented Time-Compressed And Normal Speech Stimuli, Barbara S. Moon

Dissertations and Theses

Speech compression is a method of electromyographically reducing the speech signal, resulting in a decrease in the time required for presentation of a message by increasing the number of words per minute. Research in the area of speech compression has to this time been focused on determining the listener response by means of comprehension testing. While comprehension testing uncovers the individual's ability to resolve, organize, and recall a message at accelerated rates, it gives no information about the listener's psychophysical response to compression. Does the individual find listening to compression to be tension-provoking or stressful? Or can a listener accommodate …

The Correlation Of Factors Relating To The Selection And Retention Of Student Teachers At Portland State University, Michael E. Carl

Automated Information Retrieval Systems For Legal Research, Robert G. Baylor

Dissertations and Theses

Purpose. This study of automated information retrieval systems was undertaken to attempt to ascertain the extent and development of a total legal information system.

Overview. Historically, lawyers have searched the statutes and case law in the traditionally manual method. Given consistent high standards of editing, not too complex materials, and a collection of manageable size, this manual method will work to reasonable satisfaction, so long as a document never changes in meaning or significance. Lawyers point out that the present manual system is inadequate because with 30,000 new judicial decisions and 15,000 new statutes being promulgated each year …

Post-Divorce Visitation Of Minor Children: An Exploratory Study, Barbara Griffith

Dissertations and Theses

ORS 107.100 gives the court broad powers to secure the "best interests" of minor children as third parties to a divorce. Further, the Oregon Supreme Court has ruled in Tingen vs. Tingen that the best interests of a minor child involve a complex constellation of factors pertaining to the parents, the environment, and the adjustment of the child. It has been assumed in case law that "reasonable visitation" of the minor child by the non-custodial parent is usually in the best interests of the child and is a right" of the non-custodial parent.

Most judges order reasonable visitation as part …

Non-Linearities In Galvanomagnetic Effects In Bismuth At Low Temperatures, David Lawrence Luce

Dissertations and Theses

The magnetoresistance and Hall coefficient of two single crystals of bismuth have been measured at liquid helium temperatures. The purpose of the work was to investigate the non-linearities which had previously been observed in the longitudinal and Hall voltages as a function of current. In addition to continuous current measurements, a pulsed DC technique was used in an attempt to discriminate between the non-linear effects due to heating and a possible intrinsic current dependence of the magnetoresistance and Hall coefficient. The time dependence of both of these galvanomagnetic effects indicates that the rate of heat dissipation from the crystal into …

The two professions selected were that of a physician and a social worker. It was expected that the physician, by virtue of his …

Pear Polyphenolase, Mary Ellen Tracy

Dissertations and Theses

Polyphenolases (O-diphenol: O₂ oxidoreductase E.C. 1.10.3.1) have been isolated from a wide variety of plant and animal sources. This work deals with the isolation and characterization of polyphenolase from a previously unreported source, Pyrus communis, the common pear, horticultural variety D'Anjou. The chronometric method of assay was used, in which the enzymic oxidation of the substrate, usually catechol, is coupled to the oxidation of ascorbic acid and the time required to oxidize a specific amount of substrate is noted as the time required to colorize an external startch-iodide indicator. Various methods of isolation and purification were attempted. After a suitable …

The Sex Offender In Oregon : Fact And Fallacy, Richard G. Storch, Virginia T. Peterson

Dissertations and Theses

The principal objective of this study was to examine the proposition, advanced by several authorities, that the views, attitudes and beliefs of the public concerning the sex offender and his offense are characterized by fallacy, stereotype and misconception. That the approach to the problem of the sex offense has been and continues to be primarily legislative is a fact that can be demonstrated; and that legislation reflects and is influenced by public attitudes and beliefs is a premise that can be supported. Hence the accuracy or inaccuracy of these public attitudes and beliefs will have a bearing on the legislation …

Physical And Kinetic Properties Of Dihydroorotate Dehydrogenase From Lactobacillus Bulgaricus, Craig David Taylor

Dissertations and Theses

Dihydroorotate (DRO) dehydrogenase catalyzes the oxidation of DHO to orotate in the pyrimidine biosynthetic pathway. This enzyme was originally isolated from a bacterium, Zymobacterium oroticum, which would ferment orotate as a sole source of energy. This adaptive catabolic enzyme, which catalyzes the reduction of orotate to DRO in an efficient pyridine nucleotide-linked reaction, has been extensively studied by several workers. Until recently, no study has been carried out on the enzyme which catalyzes the reaction in the biosynthetic direction. Preliminary studies have shown that the biosynthetic enzyme in Esherichia coli and a pseudomonad is not capable of reducing orotate to …

Figure Painting In The High School: Experiments And Recommendations, E. Leonora Perron

Dissertations and Theses

My research problem was to experiment with four high school art classes in drawing and painting the figure, to draw conclusions about how they relate to working with the figure, and to recommend methods that appeared to be most successful in broadening viewpoints, developing skills and increasing interest and involvement in art. This problem was selected because teenage students, in the vast majority of cases, have great difficulty in drawing or painting figures and, therefore, strenuously avoid it.

I discovered that a subjective approach that recognizes personal feelings, along with one that requires close looking, seemed to get the most …
