Output Of Compression Hearing Aids With Transient And Continuous Input Stimuli, Carol Ann Gregory

Dissertations and Theses

The purpose of this study was to determine whether the compression circuit of a hearing aid could be activated by a high frequency biasing tone such that its output for a transient stimulus could be made to approximate that of a continuous tone alone. Sufficient compression activation by a transient stimulus would mean that this type of hearing aid could be used in obtaining aided ABR measurements, since transient stimuli are commonly used for this procedure. Four hearing aids were used, and transient or continuous stimuli were introduced either alone or in combination with an 8 or 10 kHz biasing …

Internal-External Locus Of Control And The Life Experiences Of Soviet Pentecostal Refugees In Portland, Oregon, Amy Roberts

Dissertations and Theses

The construct internal-external locus of control was utilized to examine the Soviet Pentecostal refugees' perception of life experiences in the United States as defined by three dimensions: social, economical, and political. Unlike the majority of immigration research, which focuses on structural variables, this research further addressed the concept of acculturation as a long term process of resettlement. Subjects completed an anonymous forced choice questionnaire consisting of the Rotter (1966) locus of control instrument scale. Pearson Product moment correlation coefficients were calculated to examine the strength of the relationships between the internal-external locus of control scores and five factor analyzed life …

Written Narrative Texts Of Language Impaired And Normal Adolescents, Kevin Jon Penner

Dissertations and Theses

Classroom teachers frequently refer adolescents to speech language pathologists for language skills evaluations. Many of the traditional evaluation tools of the speech-language pathologist focus on the student's oral language skills. The first indication to the classroom teacher that there may be a language problem, however, is usually from the student's written classwork. Very few written language assessment tools are available which give speech language pathologists information regarding linguistic units which can be viewed as communication acts. This paper focuses on one particular discourse unit - the written narrative. Narratives are a natural form of thought and demonstrate how a person …

Percentage Of Phonological Process Usage In Expressive Language Delayed Children, Sherri Lynn Miller

Dissertations and Theses

Language delay and phonological delay have been shown to coexist. Because they so often co-occur, it is possible that they may interact, sharing a relationship during the child's development. A group of children who were "late talkers" as toddlers, achieved normal development in their syntactic ability by the preschool period. Because their language abilities are known to have increased rapidly, data on their phonological development could provide information on the relationship between phonological and syntactic development.

The purpose of this study was to compare the percentage of phonological process usage of the eight most commonly used simplification processes in four-year-old …

Analysis Of A Coordination Framework For Mapping Coarse-Grain Applications To Distributed Systems, Linda Ruth Schaefer

Dissertations and Theses

A paradigm is presented for the parallelization of coarse-grain engineering and scientific applications. The coordination framework provides structure and an organizational strategy for a parallel solution in a distributed environment. Three categories of primitives which define the coordination framework are presented: structural, transformational. and operational. The prototype of the paradigm presented in this thesis is the first step towards a programming development tool. This tool will allow non-specialist programmers to parallelize existing sequential solutions through the distribution, synchronization and collection of tasks. The distributed control, multidimensional pipeline characteristics of the paradigm provide advantages which include load balancing through the use …

Story Retelling Skills In 4-Year-Olds With Histories Of Normal And Delayed Language Development, Rita Louise Smith

Dissertations and Theses

There is a growing group of researchers who believe that narrative skills are the bridge from oral language to literacy (Culatta, Page, & Ellis, 1983; Roth & Spekman, 1989; Westby, 1989). Narrative production requires higher level language skills to create a cohesive discourse unit using decontextualized language. Narrative ability has also been found to be the best predictor for normal speech and language development for preschoolers with language impairments (Bishop & Edmundson, 1987) and reading comprehension achievement for learning-disabled, school-age children (Feagans & Applebaum, 1986) . These same skills are prerequisites for achievement of literacy and school success.

The purpose …

The Value Of The Spi In Forecasting Chronic Stuttering, Dena Diane Stork

Dissertations and Theses

Speech-language pathologists are in need of useful assessment instruments which differentiate early stuttering behaviors and will enable them to identify preschool children who need immediate intervention for stuttering. Furthermore, useful assessment tools are needed especially due to the variability across studies of normal disfluency and lack of reliability information on more formal measures of differential evaluation of normal disfluency and incipient stuttering.

Reentry Shock In The Corporate Environment, Steven A. Locke

Dissertations and Theses

While much research and attention have focused on sojourn adjustment to a new culture, very little research has addressed readjustment to the home culture. This research studies the problems of repatriation work adjustment experienced by U.S. corporate employees. This study also.suggests that cultural readjustment is situational and a multifaceted process which is influenced by many different variables. Interviews with 25 corporate repatriated employees were conducted using a 22-question survey instrument. Repatriates were asked to rate their readjustment experiences on a seven-item Likert scale. Respondents also had the opportunity to expand on their answers with open-ended questions. Fourteen variables were examined …

The Protagoras: An Explication, Victorya Khary

Anthós Journal (1990-1996)

The paper explores themes of Athenian life, Socratic philosophy, and the theme of Knowledge leading to power in the Protagoras. The setting of the Protagoras is primarily a portico at Callias’s home and Socrates debates Protagoras on numerous subjects. This paper shows that those possessing the most knowledge, Protagoras and Socrates, have the most power by invoking a pyramid structure where both Protagoras and Socrates are at the peak and give the lengthiest speeches. All of the speeches, whether by those at the top of the pyramid or the bottom, provide a glimpse into the unique nature of Athenian intellectual …

Investigations Of Self, Merlin Douglass

Anthós Journal (1990-1996)

While Margery Kempe, fourteenth century English country wife and mystic/pilgrim, and Lady Nijo, thirteenth century Japanese imperial concubine and itinerant Buddhist nun, might at first seem disparate subjects, this paper argues that the themes of pilgrimage and the act of writing an autobiography link them together in interesting ways. By tracing the ways in which both authors form their autobiographies and by using critical theories of autobiography a theme repeatedly appears, that of the welcoming nature of the wilderness of the faith pilgrimage and of the wandering paths both women took in their search for salvation

Late Holocene Paleoseismicity Along The Northern Oregon Coast, Mark Edward Darienzo

Dissertations and Theses

Marsh paleoseismological studies were conducted in four bays (Necanicum, Nestucca, Siletz, and Yaquina) along the northern Oregon coast and compared with completed studies in two other bays (Netarts and Alsea). Coseismically buried peats were identified in all bays, based on 1) abrupt contacts, decreases in organic content, increases in sand content, increases in beach sand, and changes in diatom assemblages, all from the peat to the overlying sediments, 2) distinct sandy layers and key plant macrofossils, such as Triglochin, above the buried peat, and 3) widespread correlation of the buried peats within the bay. The stratigraphy and the ages and …

International Cities In The Dual Systems Model: The Transformation Of Los Angeles And Washington, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

Though both Los Angeles and Washington, D.C., have grown into world cities since the 1940's, there are differences between them that are explained better by the two model system approach than by other approaches. Washington is distinctly and deliberately isolated from its immediate surroundings and is the center of an international information network. Los Angeles is the production and distribution center of an international region - Mexico and the United States. A valuable measure of the difference is the high proportion of professional workers in Washington, in contrast to the employment structure in Los Angeles, which closely reflects the national …

Comparison Of The Modal Frequency Levels Of Nonsmoking And Cigarette Smoking White Females Between The Ages Of Forty And Fifty Years, Janis Mae Kaufman

Dissertations and Theses

Acoustical analyses have been utilized to ascertain the functional status of the laryngeal mechanism for clinical management of communication disorders. In particular, the modal frequency level (MFL), defined as the fundamental frequency most often used by an individual in the act of spontaneous speech, is one measurement used to determine if a person's pitch level is adequate. Two other pitch measurements used in the voice assessment are the maximum frequency range (MFR) and the optimum pitch level (OPL). Information is needed to provide guidelines for pitch levels as part of the voice evaluation for adult females of different ages. It …

High Frequency Acoustic Reflexes In Cochlea-Impaired And Normal Ears, Karen Elizabeth Jones

Dissertations and Theses

The acoustic reflex refers to the contraction of a middle ear muscle in response to sound. The contraction causes a stiffening of the middle ear system and, consequently, the flow of acoustic energy to the cochlea is impeded. By measuring the change in admittance in the auditory system during sound stimulation it is possible to indirectly monitor the middle ear muscle contractions. Such measurements provide useful information regarding the integrity of the auditory system and the location of the auditory pathology.

In subjects with normal hearing sensitivity, the acoustic reflex is typically elicited at a sensation level of between 85 …

A Comparison Of Two Vocabulary Tests Used With Normal And Delayed Preschool Children, Lynn Safadi

Dissertations and Theses

The purpose of this study was to determine if a difference exists between mean standard scores of the Peabody Picture Vocabulary Test - Revised (PPVT-R) (Dunn and Dunn, 1981) and the Expressive One-Word Picture Vocabulary Test (EOWPVT) (Gardner, 1979) for children in several diagnostic categories. The subjects used in this study were 45 preschool children ranging in age from 36 to 47 months. These subjects were divided into groups of normal, expressively language-delayed (ELD) and normal children with a history of expressive language delay (HELD).

Communication Stressors And Coping Strategies Among Chinese Students In The United States, Qiu Lu Liang

Dissertations and Theses

Following China's open door policy in the late 70's and early 80's, there has been a significant increase in the number of Chinese students and scholars attending academic institutions in the U.S. As sojourners in a foreign culture, Chinese students inevitably experience difficulties in their daily life and academic endeavors. The purpose of the thesis is to examine what are the specific situations that are perceived by Chinese students as stressful, how they cope with the situations, and whether there are correlations between the perceived stressors, coping strategies, and the academic, performance of the Chinese students.

Intelligibility Of Spondees Via Bone Conduction At Elevated Presentation Levels, Pamela S. Ritchie

Dissertations and Theses

Speech reception threshold testing by bone conduction is very useful in diagnostic audiometry. However, there are little data regarding the CID W-1 spondee word lists used with the Radioear B-71 and B-72 and Pracitronic KH 70 bone conduction vibrators at higher presentation levels for testing hearing impaired clients. Data are needed in order that results of speech reception thresholds using the CID W-1 word lists via these three bone conduction vibrators at higher intensity levels can be used confidently in the clinic. More data are available for speech reception thresholds using the CID W-1 word lists via earphones.

This study …

Otitis Media And Language Development In Late Talkers, Timothy Forest Lynn

Dissertations and Theses

While there is agreement in the literature that otitis media is an extremely prevalent disorder among young children, there is disagreement as to the effect that otitis media has on language development. The lack of definitive research attests to the complexity of the issue and to the need for continued research.

This study examined the relationship between an early history of otitis media and the language development of a group of "late talkers". The 28 toddlers in this group, while otherwise normal, were late to begin to speak. Each of the subjects was placed into one of two subgroups, depending …

Developmental Sentence Scoring Sample Size Comparison, Peggy Ann Callan

Dissertations and Theses

In 1971, Lee and Canter developed a systematic tool for assessing children's expressive language: Developmental Sentence Scoring (DSS). It provides normative data against which a child's delayed or disordered language development can be compared with the normal language of children the same age. A specific scoring system is used to analyze children's use of standard English grammatical rules from a tape-recorded sample of their spontaneous speech during conversation with a clinician.

The corpus of sentences for the DSS is obtained from a sample of 50 complete, different, consecutive, intelligible, non-echolalic sentences elicited from a child in conversation with an …

Hearing Aid Satisfaction And Rate Of Return For Repairs: A Comparison Of Two Kaiser Dispensing Programs, Lynn L. Behrendsen

Dissertations and Theses

The purpose of this study was to investigate the hypothesis that a dispensing program utilizing rehabilitative follow-up in the form of a post-fitting check appointment would show: (1) less return for repairs for hearing aids; (2) higher patient satisfaction with the aid; and (3) higher patient satisfaction with the service received during the hearing aid dispense than would a clinic with no follow-up. Data for comparison between the two clinics were drawn from medical chart review, frequency of hearing aid repairs, and from a questionnaire which assessed satisfaction levels. Patients were also asked to estimate the amount of use with …

Politics And Education: The Nicaraguan Literacy Crusade, Teresa Squires Osborne

Dissertations and Theses

The Nicaraguan Literacy Crusade of 1980, carried out in the aftermath,of a long and destructive revolution, was able, in five months time, to decrease the nation's illiteracy rate from 50 percent to 13 percent. The newly fonned Nicaraguan government, recognizing the political nature of education, viewed its Literacy Crusade as a major step· in the development of a "new", post-revolutionary Nicaragua.

As a means of comparison, two other literacy campaigns are also examined: the Cuban campaign of 1961, and the UNESCO-sponsored Experimental World Literacy Programme, in place from 1965-1973.

The Cuban campaign served as a precursor to the Nicaraguan effort. …
