Independent Acoustic Stimulation Of The Amphibian And Basilar Papillae Of Rana Pipiens, Mark Parker

Dissertations and Theses

This study attempted to selectively stimulate and record from either the amphibian or basilar papillae of Rana pipiens. Computer-generated, frequency-specific clicks were used to elicit BSER's from either amphibian or basilar papillae. Narrow-band noise fatiguers were presented in the frequency region of which each papillae are tuned. It was expected that a threshold shift would be elicited in the papillae that received the acoustic trauma, and that no threshold shift would be observed from the collateral papilla.

The results of this experiment indicated that there was no overall difference between the threshold shift of either papilla. Furthermore, the amount …

Dialogue And Critical Thinking In Personal Action, Amanda Elizabeth Feller

Dissertations and Theses

A common criticism of U.S. citizens today, whether as voters or students or workers, is that they are "lazy and apathetic". It is important to explore the validity of this criticism. This thesis begins with the premise that there are two prerequisites for citizenship in a democracy: (1) that citizens be willing to participate and (2) that citizens are able to participate.

The purpose of this research is to examine a particular set of perspectives regarding social conditions which consistently impact the two aforementioned prerequisites. This examination addresses social conditions that undermine a person's ability to participate meaningfully and it …

An Exploration Of Theoretical Issues Related To Mediation Found In The Social Science Literature, Cheryl E. Nally

Dissertations and Theses

Mediation is a problem-solving approach to conflict management that is used more and more in virtually every context in which conflicts arise. This paper explores the wide range of meaning for the term 'mediation' as found in the social science literature and examines the question of what processes can properly be called mediation. It surveys the literature related to numerous theories of mediation and examines the meaning of the term as established in its various contexts.

The mediation literature can be divided into the following contexts: public sector or court connected mediation, divorce mediation, international mediation, environmental mediation, community mediation, …

A Correlational Study: The 1-Minute Measure Of Homonymy And Intelligibility, Tamra Leanne Day

Dissertations and Theses

Identifying the severity level of unintelligibility objectively and efficiently holds critical clinical implications for speech assessment and intervention needs. The speech of children who demonstrate phonological deviations is frequently unintelligible. The use of an accurate and time-efficient measurement of intelligibility is necessary to screen children who may be producing phonological patterns that contribute to significantly reduced intelligibility in connected speech.

The purpose of this study was to investigate the degree of concurrent validity between scores received on the 1-Minute Measure of Homonymy and Intelligibility (Hodson, 1992) and speech intelligibility as measured by the percent of words understood in connected speech. …

Clinical Application Of Two Phonological-Based Treatment Approaches, Holly Kiesz Royer

Dissertations and Theses

This single-subject study was designed to compare the effectiveness of two phonological-based treatment approaches with a preschool male with unintelligible speech characterized by multiple deficient phonological patterns. Four phonological patterns were chosen as targets based on results of the Assessment of Phonological ProcessesRevised (APP-R), as analyzed by the Computer Analysis of Phonological Deviation (CAPO). The subject participated in 60-minute intervention sessions three times a week over an 8-week period. The phonological cycling approach was the focus of 4 weeks of intervention, and the minimal pairs approach was the focus of 4 weeks of intervention. Remediation programs were alternated every 2 …

Fast Byte Copying: A Re-Evaluation Of The Opportunities For Optimization, Jon Inouye, Jonathan Walpole, Ke Zhang

Computer Science Faculty Publications and Presentations

High-performance byte copying is important for many operating systems because it is the principle method used for transferring data between kernel and user protection domains. For example, byte copying is commonly used for transferring data from kernel buffers to user buffers during file system read and IPC recv calls and to kernel buffers from user buffers during 'Write and-send calls. Because of its impact on overall system performance, commercial operating systems tend to employ many specialized byte copy routines, each one optimized for a different circumstance.

This paper revisits the opportunities for optimizing byte copy performance by discussing a series …

Functional Uses Of Language In The Conversational Discourse Of A Person With Alzheimer's Disease, Julie Anne Haun

Dissertations and Theses

Alzheimer's disease, the most common form of dementia, is estimated to occur in up to sixteen percent of people between the ages of 75 and 84. Deficits in linguistic skills that effect communication are a hallmark of the disease and have been the primary focus of past Alzheimer's research. Among other deficits, researchers have found that people with Alzheimer's often use indexical expressions without clear referents and convey less information that is relevant to the task they have been asked to perform than healthy subjects. Relatively little research has examined how Alzheimer's subjects use their linguistic knowledge to communicate with …

The Effectiveness Of The Phonological Cycling Approach In Treating An Unintelligible Child In The First Two Cycles Of Intervention, Anne Cole

Dissertations and Theses

One preschool male who was highly unintelligible was enrolled in two cycles of direct intervention utilizing the phonological cycling approach (Hodson & Paden, 1991). Prior to treatment in cycles 1 and 2, the Assessment of Phonological Processes-Revised (APP-R) (Hodson, 1986) was administered to the subject to assess phonological deficiencies and to determine the target phonological patterns. A continuous speech sample was collected prior to cycle 1 to rate speech intelligibility. Based on the results obtained from the APP-R, target patterns, target words, and an individualized treatment plan were developed for each cycle.

For the first cycle of intervention, the subject …

Validity And Efficiency Of The Check-Slash Transcription Method For Measuring Intelligibility, Vicky Jo Bacon

Dissertations and Theses

Speech-language pathologists are routinely called upon to make professional assessments concerning a speaker's level of intelligibility. The use of subjective judgement procedures for estimating a percentage of intelligibility is the general practice of many speech-language pathologists because they require minimal time. Although efficient, these methods lack any form of numerical support, and their validity and reliability is questionable. The standard within the field that provides data support is the orthographic transcription method, but it is considered to be too time-consuming for practical application (Samar & Metz, 1988). Researchers continue to seek a measure that is both valid and efficient to …

Empowering Esl Students For Out Of Classroom Learning, Jay Stanley Neuharth

Dissertations and Theses

ESL students virtually swim in an environment rich in opportunities to learn English. Every billboard, newspaper, TV show, and person on the street provides new language. However, many ESL students do not take full advantage of this English environment. Often, English learning is viewed primarily as a classroom experience, when much more could be gained if students were learners outside the classroom, as well. That is the problem addressed in this thesis.

This problem was investigated through action research with the teacher/researcher's high intermediate level writing class at PSU. The teacher/researcher implemented a strategy to motivate students to learn outside …

A Study Of The Duration Of Words Surrounding A Moment Of Stuttering, Jennifer Dawn Peterson

Dissertations and Theses

Until this point, not much research has examined the difference in temporal characteristics for untreated stutterers in words surrounding a moment of stuttering. It is important to determine whether or not stutterers who have not been in treatment alter the duration of their speech when they stutter versus when they are fluent to determine what aids in the increase of fluency. The purpose of the present study was to examine the duration of the word prior to and following a stuttered word and the duration of the corresponding word in a nonstuttered episode. The following questions were to be addressed: …

Comparison Of Prescribed Versus Actual Gain For Children With Profound Hearing Impairments, Kristin Rashelle Gilmer

Dissertations and Theses

The early selection and use of an appropriate amplification system may be the most important aspect in the aural! rehabilitation of children who are hearing impaired. The main goal guiding the selection of hearing aids for children is to maximize their residual hearing through amplification in order to facilitate speech and language development.

Seewald, Ross, and Stelmachciwicz (1987) have developed a speech-spectrum based procedure for selecting hearing aid characteristics for children referred to as the Desired Sensation Level Procedure (DSL) approach. This is an objective method which has been developed specifically for use with young pre-verbal children.

The purpose of …

The Effect Of A Physician's Pronunciation On Nurses' Perceptions Of The Physician's Medical Competency, Laura Anne Horani

Dissertations and Theses

Although many researchers have studied language attitudes in the last three decades, none of the studies have been conducted in the hospital setting, where there are more serious consequences for those working with patients being labeled linguistically "incompetent," as charges of incompetence in language are apt to lead to charges of incompetence in other areas of mastery as well (e.g., Ryan, 1983). This study examines the attitudes of a sample of nurses from three Portland-area hospitals towards nonnative English speaking physicians. The subjects, 156 medical-surgical nurses, listened to three anonymous audiotaped physicians who were from three different ethnic backgrounds: American, …

Differentiable Circle Maps With A Flat Interval, J. Graczyk, L. B. Jonker, G. Swiatek, F. M. Tangerman, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

We study weakly order preserving circle maps with a flat interval, which are differentiable even on the boundary of the flat interval. We obtain estimates on the Lebesgue measure and the Hausdorff dimension of the non-wandering set. Also, a sharp transition is found from degenerate geometry to bounded geometry, depending on the degree of the singularities at the boundary of the flat interval.

Mist: Pvm With Transparent Migration And Checkpointing, Jeremy Casas, Dan Clark, Phil Galbiati, Ravi Konuru, Steve Otto, Robert Prouty, Jonathan Walpole

Computer Science Faculty Publications and Presentations

We are currently involved in research to enable PVM to take advantage of shared networks of workstations (NOWs) more effectively. In such a computing environment, it is important to utilize workstations unobtrusively and recover from machine failures. Towards this goal, we have enhanced PVM with transparent task migration, checkpointing, and global scheduling. These enhancements are part of the MIST project which takes an open systems approach in developing a cohesive, distributed parallel computing environment. This open systems approach promotes plug-and-play integration of independently developed modules, such as Condor, DQS, A VS, Prospero, XPVM, PIOUS, Ptools, etc. Transparent task migration, in …

The Effects Of Ear Canal Pressure Variation On Distortion Product Otoacoustic Emissions, Jodi L. Head

Dissertations and Theses

The middle ear system is a vital component in the propagation mechanism of otoacoustic emissions. As such, investigation of the effect of variation in middle ear impedance on the measurement of emissions is warranted.

Distortion product otoacoustic emissions (DPOAEs) have gained recognition as a means of gaining frequency specific information on auditory function. As the effects of changes in middle ear impedance will vary as a function of frequency, a clear definition of the relationship between middle ear impedance and DPOAE amplitude across the frequency spectrum is needed.

Twenty adults (ages 20-37) with normal hearing and normal middle ear function …

Evolving Globally Synchronized Cellular Automata, Rajarshi Das, James P. Crutchfield, Melanie Mitchell, James M. Hanson

Computer Science Faculty Publications and Presentations

How does an evolutionary process interact with a decentralized, distributed system in order to produce globally coordinated behavior? Using a genetic algorithm (GA) to evolve cellular automata (CAs), we show that the evolution of spontaneous synchronization, one type of emergent coordination, takes advantage of the underlying medium's potential to form embedded particles. The particles, typically phase defects between synchronous regions, are designed by the evolutionary process to resolve frustrations in the global phase. We describe in detail one typical solution discovered by the GA, delineating the discovered synchronization algorithm in terms of embedded particles and their interactions. We also use …
