Burns'eko Etxekoandreak: Basque Women Boarding House Keepers Of Burns, Oregon, Paquita Lucia Garatea

Dissertations and Theses

The migration of the Basques to the Pacific Northwest at the turn of the century was due to a number of factors including economic, cultural and political. The Basques constitute a distinct ethnic group from northern Spain and southern France, whose origins have not yet been determined by historical, linguistic, or archaeological studies. From ancient times, the Basques have fought to maintain their cultural identity and political freedom against invaders, developing in this struggle a strong sense of racial group solidarity. The lack of opportunity for advancement and the obligation to serve in the military were added reasons for the …

Determinants Of 2000 Meter Rowing Ergometer Performance, Jeff C. Young

Dissertations and Theses

Lean body weight and aerobic and anaerobic factors have long been recognized as important determinants of performance in the 2000 meter (M) race distance for rowing. Current research with noninvasive techniques has important implications for training and performance but is inconclusive. The purpose of this study was to investigate the relationship between a 2000 M rowing ergometer performance test (PT) and lean body weight (LBW), velocity at heart rate deflection (Vd), and anaerobic capacity (AC) in experienced rowers. Vd was used as an estimate of aerobic function. Thirteen trained male rowers (mean age 38.5 ± 8 years) were studied. Hydrostatic …

Differentially Diagnosing Stuttering In Young Children Using The Stuttering Severity Instrument, Brenda Pekkola Teich

Dissertations and Theses

Young children between the ages of two and six years often exhibit partword, whole word. and phrases repetitions as their language develops. This is also the age range when stuttering most frequently appears. Consequently. speech-language pathologists need diagnostic criteria and evaluation tools to distinguish between the incipient stutterer and the normally disfluent child.

Today a widely used evaluation tool is the Stuttering Severity Instrument (SSI) (Riley, 1972, 1980). The SSI is designed to provide a severity level based upon the parameters of frequency. duration. and physical concomitants. Riley (1972) first designed the SSI to not include monosyllabic word repetitions in …

The Effect Of Plant Growth Regulators On The Growth Of Closterium Moniliferum, Cynthia Lehua Warnock Christensen

Dissertations and Theses

Physiologic responses to Gibberellic Acid (GA), 1-Naphthalene Acetic Acid (NAA), Benzylaminopurine (BAP), and Abscisic Acid (ABA), suggest that Closterium moniliferum has the ability to utilize these plant growth factors. The growth promoters NAA and GA both increased growth when added to the media. The cell division regulator BAP (a synthetic cytokinin). also had a promotive effect on growth. Abscisic acid was found to be inhibitive to growth.

A Comparison Of Two Methods For Measuring The Attenuation Provided By Insert-Type Hearing Protection Devices, Brenda Barrett Kabat

Dissertations and Theses

The need for hearing protection in industry has evolved from the growing awareness of the detrimental effects of noise on hearing and recent legislation enacted to protect the hearing of noise-exposed employees through the use of hearing conservation programs.

Hplc Analysis Of Myoglobin Tryptic Peptides From Selected Species Of Cetaceans, David Lawrence Hayteas

Dissertations and Theses

Due to the large gaps in the fossil record, the evolutionary history of the mammalian order Cetacea is incomplete and controversial. Increasingly researchers are utilizing molecular and biochemical procedures to supplement cetacean paleontology. One of these methods is the comparison of amino acid sequences of myoglobin among species of this order. since this method is time-consuming and expensive, an alternative procedure is desirable.

As a candidate for such an alternative, peptide mapping was performed on selected species of cetaceans. This mapping was done utilizing High Performance Liquid Chromatography (HPLC). Myoglobin was extracted from skeletal muscle, purified, digested with trypsin, the …

Investigation Of Techniques For High Speed Cmos Arbitrary Waveform Generation, Albert Henry Nehl

Dissertations and Theses

Today a growing number of applications in design engineering, production and environmental testing, and system service require specific analog waveforms and digital patterns. Such requirements are neither satisfactorily nor easily met by the use of standard function or single purpose, custom generators.

Traditional methods of waveform generation suffer from undesirable complexity or mediocre performance and are otherwise limited. For the majority of arbitrary waveform generation applications, including medical engineering, modal analysis and electronic engineering, direct digital synthesis techniques are satisfactory. Direct digital synthesis, based generally on periodic retrieval of predetermined amplitude values, may be used to generate such waveforms. Within …

Performance Analysis Of A Distributed File System, Meenakshi Mukhopadhyay

Dissertations and Theses

An important design goal of a distributed file system, a component of many distributed systems, is to provide UNIX file access semantics, e.g., the result of any write system call is visible by all processes as soon as the call completes. In a distributed environment, these semantics are difficult to implement because processes on different machines do not share kernel cache and data structures. Strong data consistency guarantees may be provided only at the expense of performance.

This work investigates the time costs paid by AFS 3.0, which uses a callback mechanism to provide consistency guarantees, and those paid by …

Study Of Referential And Display Questions And Their Responses In Adult Esl Reading Classes, Susan Lindenmeyer

Dissertations and Theses

The technique of asking questions in the classroom has prevailed in first language classes for many years. This teaching technique has also been widely used in ESL reading classes. Though there has been extensive research about teachers' questions and students' responses in first language classrooms, there is a paucity of studies in second language classrooms.

This is a descriptive study of six experienced college level English as a Second Language (ESL) teachers and their discussions of the same reading selection with ninety-eight non-native speakers in each of their classes. Teacher-led discussions were audiotaped and twenty minutes of each class were …

Dissertations and Theses

The present study explores the knowledge, attitudes, and opinions about dreams held by 394 high school, community college, and university students, and examines the interrelations among these students' responses to questions concerning such knowledge, attitudes, and opinions. A modified and extended form of George Domino's Questionnaire About Dreams (QAD) was used for obtaining a descriptive account of students' orientations toward dreams. Scales were developed for summarizing respondents' orientations toward dreams, and the reliability and validity of these scales was investigated. The reliability of scales for assessing respondents' attitudes, psychodynamic orientation, and to a lesser degree paranormal orientation was demonstrated. A …

Nietzsche's "Woman" : A Metaphor Without Brakes, Kathleen Merrow

Dissertations and Theses

This thesis reconsiders the generally held view that Friedrich Nietzsche's works are misogynist. In doing so it provides an interpretation of Nietzsche's texts with respect to the metaphor "woman," sets this interpretation into an historical context of Nietzsche reception and follows the extension of Nietzsche's metaphor "woman" into French feminist theory. It provides an interpretation that shows that a misogynist reading of Nietzsche is in error because such a reading fails to consider the multiple perspectives that operate in Nietzsche's texts.

Spatial Manipulation As A Covariant Of Mental Practice, Vincent James Wolff

Dissertations and Theses

This experiment examined the relationship between a subject's ability to manipulate spatial relationships and utilize mental practice in the mirror drawing ability of 45 naive volunteer college students, using a six-pointed star track. The spatial manipulation abilities of all subjects were assessed with the Minnesota Paper Form Board Test, after which the subjects were divided into three treatment groups (no practice, mental practice, and physical practice) of 15 subjects using a blocked random design based upon their MPFBT scores. All three groups were trained in the mirror drawing task and given three physical practice pre-trials for familiarization. The physical practice …

The Unified Speech Period Of A Bilingual Child, Gary Frank Wood

Dissertations and Theses

Previous studies of bilingual infants learning their languages simultaneously have suggested that such children go through what is known as a unified speech period in which they make no differentation between the languages in question and in which they frequently use mixed utterances (Arnberg, 1987; Grosjen, 1982; Leopold, 1939; & Skutnabb-Kangas, 1981). To test the validity of the claim that there is such a period, an English-Japanese bilingual child from one year and six months of age (1;6) through two years and six months of age (2;6) was observed and his speech recorded.
