Comment On Electron Scattering In The Image Potential Well, Pavel Smejtek, M. Silver

Physics Faculty Publications and Presentations

Comments are made on the model of electron injection into SiO₂ proposed by Berglund and Powell. Their assumptions on electron scattering, disregarding the change of the escape cone with the distance from the emitter, lead to serious underestimation of the injected current. Two alternative models of electron injection, based solely on elastic scattering are discussed and do not predict the experimental results. We suggest that observed field dependence of the injected current into SiO₂ indicates that energy relaxation associated with the injected electrons is responsible for the voltage dependence of the current.

Geophysical And Geological Analysis Of A Fault-Like Linearity In The Lower Clackamas River Area, Clackamas County, Oregon, Ronald Jay Schmela

Dissertations and Theses

A fault-like linearity along the lower Clackamas River is evaluated by analysis of physiographic and structural alignments, geological relationships, and by gravity and magnetic data. The study has resulted in the verification of a structural feature extending along the Clackamas River and the eastern front of the Portland Hills.

Physiographic alignments were examined in twelve 15 minute and two 7-1/2 minute quadrangle maps. A significant northeasterly morphologic trend, N. 20⁰ W. and N. 40° W., and other secondary trends, namely, the N-S, E-W, and N. 50-60° E., has developed in the Portland area. The consistent northwest trend is observed throughout …

Ames Trapezoid Illusion: A New Model, Daniel Robert Kelly

Dissertations and Theses

Current explanations for the Ames Trapezoid Illusion are based upon the the absence of cues: the illusion is said to occur at chance. A review of recent literature showed that: (a) the illusion varies in frequency as a function of target shape (b) that the dominant cue to reduce the frequency of the illusion is the variant in retinal height. Based upon the dominance of this cue a new model was presented. Following this model it was hypothesized that observers viewing partial rotation when the target produces the greatest difference in the retinal height of the ends would determine the …

Vocalizations Of The Townsend Chipmunk (Eutamias Townsendii), Greig Michael Warner

Dissertations and Theses

This study describes and analyzes the vocalizations of the Townsend chipmunk (Eutamias townsendii) in Oregon. Tape recordings of calls were collected primarily from Forest Park in Portland (Oregon) during 1970 and 1971, and sonograms of these recordings were produced. Findings were compared with those of Brand (1970) who investigated E. townsendii vocalizations in California. The prominent calls in the vocal repertoire of townsendii are the quist, the quirt, and the chipper. These calls all appear to be warning calls. The quist note is a a chevron-shaped (A) figure representing a sound which begins at a low frequency (1-2 KC), sharply …

Evidence For The Existence Of Two Stable Sites For Cobalt Impurity Atoms In Aluminum, Arun Venkatachar

Dissertations and Theses

Using Fe⁵⁷Mössbauer spectroscopy, two alternative sites occupied by cobalt (10^-4 at. % ) impurity atoms in aluminum have been isolated. The substitutional site A is the stable position after annealing the sample above 840 K, followed by a rapid quench. The impurity atoms in site A are characterized by a single line Mössbauer spectrum (indicative of a cubic environment), a room-temperature f = 0.502 (r. m. s. displ. 0.071 A) and an I. S. (reI. to Fe) = -0.421 mm/sec. For anneals below 770 K the cobalt atoms migrate to site B, which is characterized by a …

Inter-Bureau Power Relations: A Sociological Analysis Of An Ideal Type Organizational Model, Gerald Wayne Potterf

Dissertations and Theses

The research problem of this thesis is an examination of inter-bureau power relations. A modification of Max Weber's classical ideal type bureaucracy is the conceptual model to which sociological analysis is made. An empirical examination of the variance between the conceptual model and data collected in the field is analyzed in order to illustrate inter-bureau power relations. The analysis of the conceptual model is based upon three assertions. They are: (1) inter-bureau power relations are based upon coercion and not cooperation; (2) normative standards that are established by the administrators of the bureaucracy are differentially enforced; and (3) goals that …

Hipólito Irigoyen's Second Administration: A Study In Administrative Collapse, Herman John Hobi

Dissertations and Theses

In 1928 Hipólito lrigoyen was the most popular President that the Argentine people had elected. Two years later his popularity had evaporated and a few hundred military cadets ousted the government. The reasons go beyond this two-year period. Argentina, contrary to popular belief, did not have a democratic tradition. The nation had been ruled by the dominant economic interests up to 1916.

In 1916, Hipólito Irigoyen was elected to his first term. The people expected him to provide them with a decent and honorable life. But in choosing the legal path of elections instead of revolution Irigoyen pre-empted any revolutionary …

On The Molecular Theory Of Dielectric Polarization In Rigid‐Dipole Fluids, John D. Ramshaw

Physics Faculty Publications and Presentations

A molecular theory is developed for the polarization P(r) produced by a weak position‐dependent external electric field E₀(r) in a finite fluid system, of arbitrary shape, composed of rigid polar molecules. The theory differs from earlier work in that no assumption is made concerning the form of the electrostatic constitutive relation. [The usual assumption in this regard is that P(r) = (ε–1) E(r) / 4π, where E(r) is the total Maxwell electric field. The “dielectric constant” ε is well defined only if the relation between P(r) and E(r) …

The Effectiveness Of Environmental Control In Modifying Problem Behaviors In Mother-Child Interaction, Thomas Whalen Hamilton

Dissertations and Theses

An experiment was designed to test the effectiveness of using standard laboratory environments in producing a broad class of problem behaviors which defined Mother-Child (M-C) interaction difficulties. The effects of four environments, free-time (X), child's game and rules (B), mother's game and rules (C), and clean-up (Z), on the frequency of eight criteria behaviors were tested on 12 M-C pairs over three days of baseline data collection. It was predicted that the frequency of problem behaviors would decrease as a function of environment (X) and increase as a function of environments (B), (C), and (Z). A two factor …

Crystal Structure Determination Of Β-Lactoglobulin From Electron Micrographs, Richard Roeter

Dissertations and Theses

Often electron micrographs exhibit a repeating structure. Sometimes this repeating structure satisfies the definition of a crystal in that it has a three dimensional repeating structure. If the unit cell structure of this repeating structure can be determined it can be used to help categorize different sections of a particular sample. In some cases, the use of optical diffraction analysis of electron micrographs with repeating structure is a method of determining the unit cell structure.

Samples of β-Lactoglobulin were prepared for viewing in the electron microscope using both the crystalline material and carbon replicas of the crystal surface. Because the …

Communicative Abilities: An Analysis Of The Interactions Of Reticent And Non-Reticent Task Groups, Myron W. Lustig

Dissertations and Theses

This study is focused upon an investigation of observable interactive behaviors which might be characteristic of reticence. A reticent individual is defined as one for whom apprehension about participation in oral communication consistently outweighs the projection of gain from the situation.

Previous research in the area of reticence has been focused on an analysis of the reticent student's attitudes toward communication relying primarily upon subject self-reports via journals and the in-depth interview. This in turn has provided possible areas in which observable reticent behaviors might evidence themselves in face-to-face small group communications with other reticents and non-reticents.

An answer to …

Implications Of An Oral-Gestural Training Program In The Acquisition Of Speechreading Skills, Mary Lu Wood

Dissertations and Theses

In order for the hearing handicapped child to derive maximum benefit of language acquisition through maturation, a method of receptive communication is essential at the earliest age possible. It is felt that speechreading is this method. The need for a method of training speechreading cues to prelingual, aurally handicapped children is based on the fact that most visual speechreading methods require the use of language. If speechreading can be regarded as a learning process involving the discrimination of visual cues that maybe disassociated from language expression then training the child to discriminate various facial expressions may actually enhance speech-reading ability. …

Rilke Und ValéRy: Eine Wahlverwandtschaft, Anne Marie Roehr

Dissertations and Theses

The German poet Rainer Maria Rilke was proficient in languages, and his favorite one was French. He had lived in Paris and had many friends in French literary circles. He exchanged letters with some of them before he even met them personally; such was the case with the French poet and writer Paul Valéry. However, before the two poets met, a “meeting of the minds” had taken place in the year 1921.

In the spring of 1921, after a lengthy period of silence, Rilke came across a copy of the Nouvelle Revue Française, a famous literary review, where Valèry had …

The Effects Of Marihuana Extract Distillate On Eating Behavior Of Rats, Terrie Wetle

Dissertations and Theses

Since hunger drive is often used as a motivating factor in animal learning experimentation, it was decided to determine the effects of marihuana extract distillate on the eating behavior of rats. Carlini and Kramer (1965) found marihuana extract injections to have a faciliatory effect upon maze performance. They suggested that facilitation could have resulted from and increase in hunger drive. However, if the dosage level is high, this effect may last for a short time and be followed by a disinterest in food. Scheckel et al. (1968) report that some monkeys, at very high dosage levels of tetrahydrocannabinol starved to …

Age, Emotional Maturity And The Decision To Marry, Patricia Ann Duclos, David F. Thomas, Joanne Zusman

Dissertations and Theses

The decision to marry and choice of mate are two issues contemplated by most individuals during their lifetime. It is our belief that the manner in which an individual makes these decisions is a reflection of that individual’s level of emotional maturity.

In our society, the right to enter into a marriage agreement is largely determined by chronological age. Our research problem began with the hypothesis that there is no direct relationship between chronological age and emotional maturity at the time of marriage.

For our study, marriages were divided into two general categories: 1) teenage marriages in which at least …

An Interactional Approach To Weight Reduction, Carole T. Gygi

Dissertations and Theses

A treatment program was designed to enable subjects to lose weight through the use of self-confrontation as described in Saslow (1969), and the use of the General Relationship Improvement of the Human Development Institute (HDI), Berlin and Wyckoff (1964).

Self-confrontation is a programmed rehearsal of a specific problem by one person alone, for a five-minute period. The rehearsal, or self-confrontation is to be as vivid as possible, intellectually, emotionally, visually and physically.

The General Relationship Improvement Program is a 10-week text, worked in pairs, which is aimed at better intrapsychic and interpersonal communication and understanding.

Four matched groups were used …

Comparative Study Of Lightweight And Normal Weight Concrete In Flexure, Mohammad Zareh

Dissertations and Theses

This investigation represents a comparative study of the flexural behavior of lightweight and normal weight concrete. Both theoretical and experimental moment-curvature characteristics of the tested specimens were used to study the flexural behavior.

A generalized computer program to determine the moment-curvature relationships of a singly reinforced rectangular concrete beam was developed.

For this limited study it was observed that lightweight concrete beams when compared to normal concrete beams achieve comparable moment capacity (about 92% of normal weight concrete) but exhibit higher deflections (about 40% more than normal weight concrete).

An Analysis Of The Ability And Achievement Of Business Education Students Compared To Non-Business Education Students, William B. Warberg

Dissertations and Theses

Since some educators believe the underachiever and the low-ability student are frequently placed in business education classes for the purpose of finding him an easy way through school, this study attempts to determine just where the business education student actually ranks in achievement and ability as compared to students in other academic areas.

The students used in this study come from the graduating classes of 1969 and 1970 of Beaverton and Sunset High Schools in Beaverton, Oregon. A business education student has been defined as one who has successfully completed at least two of the following courses: Shorthand II; Office …

Foster Family Care For The Aged, Donald V. Sekora

Dissertations and Theses

The following was a research practicum instituted as an actual project for the State of Montana Welfare Department between June, 1970, and May, 1971. The project had a two-fold purpose in being conceived: one purpose was to fulfill a graduate school academic requirement; and the second purpose was to fulfill a responsibility to the people of Montana who would eventually gain some benefits from this project. The series of written documents that follow are the description of that project's conception and actualization in six Montana counties. The first part is the project idea and theory; the next two parts consist …

An Attempt To Find Predictor Variables Which Will Discriminate Between Those Patients Who Seek Aftercare Treatment And Those Who Do Not Seek Aftercare Treatment Upon Discharge From A Psychiatric Ward, Nena V. Johnstone, William D. Lynch, Philip M. Baldwin, John C. Kemp

Dissertations and Theses

This is an exploratory follow-up study of the clientele of the Psychiatric Crisis Unit, a short-term, crisis-oriented inpatient psychiatric ward. The main objective of the research was to test the following null hypothesis: there are no significant differences between those individuals who attempt to gain aftercare treatment as opposed to those individuals who do not following discharge from the Crisis Unit.

A sample of fifty-one voluntary patients who consented to participate in the study was used in testing this hypothesis. Each subject completed the Minnesota Multiphasic Personality Inventory (M.M.P.I.) and a sociological questionnaire while in the Crisis Unit, and a …

François Pierre Guillaume Guizot: An Intellectual Approach, Elbert Hardy Cave

Dissertations and Theses

The problem of this study was to present an intellectual picture of a man who is too often written off as a mere politician and a failure at that.

In approaching the problem, his works were used heavily, though availability was a problem. François Guizot, the man studied, wrote profusely, on a large variety of subjects, including philosophy, religion, history, political theory, and education. All of these areas were covered in the study. His private papers and correspondence are, for the most part, unpublished, though the eight volumes of his Mémoires were extremely helpful.

There are many good biographical studies …
