A Study Comparing Musical Abilities Of Stutterers And Nonstutterers, Megan Creswell

Dissertations and Theses

Rhythm is a feature of both music and speech that has been successfully used in the treatment of speech disorders, particularly stuttering, for many years. The successful use of rhythm in the treatment of dysf luencies of speech may be due to stutterers' perceptual deficiencies in music and rhythm abilities. Research supports the view that there are differences between stutterers and nonstutterers in timing and rhythmic capabilities. This study, therefore, sought to determine whether there was a difference between the perceptual musical abilities of stutterers versus nonstutterers as measured by the Seashore Measures of Musical Talents, Revised (1960). Data collected …

Sri Lanka's "Army Of Housemaids": Control Of Remittances And Gender Transformations, Michele Ruth Gamburd

Anthropology Faculty Publications and Presentations

When the mass labor migration of women to the Middle East began in the early 1980's, many Sri Lankan social scientists predicted a revolution in gender equality and a greater participation by women in political and economic decision-making as a result of employment abroad. Noting that gender rarely correlates in predictable ways with social change, and questioning the dominant teleological ideology that change always happens for the better, this paper looks at relations between female migrants in a coastal village in the Southwest and the people responsible for spending and saving the money they remit to the village. Several case …

Limiting Noise Exposure Associated With Hearing Aid Use, Alison Mary Gilbert

Dissertations and Theses

Industrial workers who have sustained hearing losses often wear hearing aids on the job in order to hear their co-worker's speech. However they risk damaging their hearing further by amplifying the high levels of background noise typical of such environments. The Occupational Safety and Health Administration (OSHA) has established guidelines to protect workers' hearing. A maximum allowable level of 90 dBA averaged over a period of eight hours is considered safe. Wearing hearing aids on the job may expose an individual to considerably higher levels, however no guidelines as to maximum allowable levels of amplified noise exist at this time. …

Adaptive Methods For Distributed Video Presentation, Crispin Cowan, Shanwei Cen, Jonathan Walpole, Carlton Pu

Computer Science Faculty Publications and Presentations

This paper describes problems and solutions for delivering real-time, multi-media presentations across the Internet. A key characteristic of presentations of continuous media datatypes, such as digital video and audio, is their need for predictable real-time data delivery. For example, an NTSC quality video presentation requires video frames to be displayed every 1/30th of a second. Variations in this display rate can be observable as stalls or glitches in the video stream and reduce the quality of the presentation [6]. Delivering such presentations across the Internet is difficult because highly variable band- width and latency make it difficult to predict the …

Effects Of Receptive Language Deficits On Persisting Expressive Language Delays, Traci Lee Giacherro

Dissertations and Theses

Predicting language outcomes in children who at age two are "late talkers" is a concern of Speech Language Pathologists. Currently, there is no conclusive data allowing specialists to predict which children will outgrow their delays and which children will not. The purpose of the present study is to analyze the effect of a receptive language delay on the outcome of the slow expressive language delayed child, and determine whether or not it is a viable predictor of poor outcomes.

The subject information used in this project was compiled from the data collected and reported by Paul (1991) during the Portland …

Customizable Operating Systems, Jonathan Walpole, Crispin Cowan, Andrew P. Black, Jon Inouye, Calton Pu, Shanwei Cen

Computer Science Faculty Publications and Presentations

A customizable operating system is one that can adapt to improve its functionality or performance. The need for customizable and application-specific operating systems has been recognized for many years, but they have yet to appear in the commercial market. This paper explores the notion of operating system customizability and examines the limits of existing approaches. The paper begins by surveying system structuring approaches for the safe and efficient execution of customizable operating systems. Then it discusses the burden that existing approaches impose on application software, and explores techniques for reducing this burden. Finally, support for customizability in the Synthetix project …

Device And Physical Data Independence For Multimedia Presentations, Richard Staehli, Jonathan Walpole, David Maier

Computer Science Faculty Publications and Presentations

Multimedia computing promises access to any type of visual or aural medium on the desktop. But in this networked future, will every type of media be accessible from every terminal device? Current multimedia standards do not allow content that is authored for high-bandwidth workstations to scale down for low-bandwidth applications. The problem is that application requests are commonly interpreted as requests for the highest possible quality and resource overloads are handled by ad hoc methods. We can begin to solve this problem by specifying Quality of Service (QOS) requirements based on functionality rather than on content encoding and device capabilities.

Quality Of Service Specification For Multimedia Presentations, Richard Staehli, Jonathan Walpole, David Maier

Computer Science Faculty Publications and Presentations

The bandwidth limitations of multimedia systems force tradeoffs between presentation data fidelity and real-time performance. For example, digital video is commonly encoded with lossy compression to reduce bandwidth and frames may be skipped during playback to maintain synchronization. These tradeoffs depend on device performance and physical data representations that are hidden by a database system. If a multimedia database is to support digital video and other continuous media data types, we argue that the database should provide a Quality of Service (QOS) interface to allow application control of presentation timing and information loss tradeoffs.

This paper proposes a data model …

Performance Evaluation Of Specialized Hardware For Fast Global Operations On Distributed Memory Multicomputers, Rajesh Madukkarumukumana Sankaran

Dissertations and Theses

Workstation cluster multicomputers are increasingly being applied for solving scientific problems that require massive computing power. Parallel Virtual Machine (PVM) is a popular message-passing model used to program these clusters. One of the major performance limiting factors for cluster multicomputers is their inefficiency in performing parallel program operations involving collective communications. These operations include synchronization, global reduction, broadcast/multicast operations and orderly access to shared global variables. Hall has demonstrated that a .secondary network with wide tree topology and centralized coordination processors (COP) could improve the performance of global operations on a variety of distributed architectures [Hall94a]. My hypothesis was that …

Communicative Action As Feminist Epistemology, Todd Nathaniel Gilman

Dissertations and Theses

This thesis proposes that feminist social and political theory adopt the epistemology inherent in Jurgen Habermas's communicative ethics in order to more coherently work toward the goal of freeing individuals from social oppression. This thesis first examines the fundamental differences that exist between the particular claims for knowledge made by the three major schools of feminist theory; the empirical feminists, the standpoint feminists, and those allied with postmodernism. After illuminating the specifics of these feminist claims, the conception of knowledge central to Habermas's thought is explored and shown to be split into three distinct realms; the objective, the social, and …

Performance Analysis Of A Banyan Based Atm Switching Fabric With Packet Priority, Zhaohui Yan

Dissertations and Theses

Since the emergence of the Asynchronous Transfer Mode ( A TM ) concept, various switching architectures have been proposed. The multistage interconnection networks have been proposed for the switching architecture under the A TM environment. In this thesis, we propose a new model for the performance analysis of an A TM switching fabric based on single-buffered Banyan network. In this model, we use a three-state, i.e., "empty", "new" and "blocked" Markov chain model to describe the behavior of the buffer within a switching element. In addition to traditional statistical analysis including throughput and delay, we also examine the delay variation. …

The project that team quintuple was assigned is the self-diagnosis or analysis of factors that impacted our team's performance throughout the course.

We were assigned a number of team tasks for the class that required interacting and discussing those tasks with other members, and of course performing those tasks. Those activities were the vehicles used by our team to access how well we had worked together. We noted our observations in individual journals to help us in analyzing factors at the end of the project life cycle. Several tracking tools were used in addition to journals, such as our weekly …

Doubled Co2 Experiments With The Global Change Research Center Two-Dimensional Statistical Dynamical Climate Model, R. M. Mackay, M. A. K. Khalil

Physics Faculty Publications and Presentations

The zonally averaged response of the Global Change Research Center two-dimensional statistical dynamical climate model (GCRC 2-D SDCM) to a doubling of atmospheric carbon dioxide (350 parts per million by volume (ppmv) to 700 ppmv) is reported. The model solves the two-dimensional primitive equations in finite difference form (mass continuity, Newton's second law, and the first law of thermodynamics) for the prognostic variables: zonal mean density, zonal mean zonal velocity, zonal mean meridional velocity, and zonal mean temperature on a grid that has 18 nodes in latitude and 9 vertical nodes (plus the surface). The equation of state, p=rhoRT, and …

Research and Training Center - Focal Point

Men are increasingly discovering the many joys of active involvement in their children's lives. The special bond between father and child produces measurable, positive effects in regards to a child's self-esteem, gender identity, intellectual growth, curiosity and social skills. Current literature increasingly portrays dads as caretakers, supportive, sensitive and caring. However, this enhanced involvement can be sorely tested when a child has a disability or chronic illness. The dreams fathers have for their child's life, educational, athletic and vocational achievements are threatened.

Fluttering Fountains: Annular Geometry, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

Under certain conditions of flow rate, height, and feedback, periodic or chaotic fluttering oscillations can be observed as the sheet of water from a dam or waterfall fountain descends through the air. Numerical and analytical interpretations of this phenomenon have recently been reported. The extension of these results to other fountain geometries is discussed here together with experimental observations on an annular waterfall fountain.

The Affects Of Vocal Fatigue On Fundamental Frequency And Frequency Range In Actresses As Opposed To Non-Actresses, Ruth Ann Jenkins

Dissertations and Theses

Differences may exist between the voice qualities of those who professionally use and train their voices and those who do not. The examination of fundamental frequency and frequency range m actresses and non-actresses is integral to determining voice quality differences in these populations. These differences, whether the result of frequent use or training of the voice, may exist relative to fatiguing conditions such as may be experienced by actresses in the course of their work. Fatigue has been shown to produce greater effects in normals than in performers, particularly in singers (Gelfer, Andrews, and Schmidt, 1991). Little research has been …

Data Allocation For Distributed Programs, Liono Setiowijoso

Dissertations and Theses

This thesis shows that both data and code must be efficiently distributed to achieve good performance in a distributed system. Most previous research has either tried to distribute code structures to improve parallelism or to distribute data to reduce communication costs. Code distribution (exploiting functional parallelism) is an effort to distribute or to duplicate function codes to optimize parallel performance. On the other hand, data distribution tries to place data structures as close as possible to the function codes that use it, so that communication cost can be reduced.

In particular, dataflow researchers have primarily focused on code partitioning and …

Behavioral Differences In The Classroom: U.S. University Teachers And Chinese University Teachers, Xiaocheih Sun

Dissertations and Theses

Although intercultural scholars examine the differences in cultural values, beliefs, and attitudes between the U.S. and China, few specifically have studied cultural differences between U.S. and Chinese university classrooms. This study examines behavioral differences exhibited by U.S. teachers in U.S. university classrooms and Chinese teachers in Chinese university classrooms.

This research addresses three areas of significance. First, Chinese students studying in the U.S. who read this thesis may be better able to cope with the U.S. educational system and communicate more effectively with both U.S. students and teachers. Second, this research may help U.S. university teachers to better understand the …
