Adaptation Space: Surviving Non-Maskable Failures, Crispin Cowan, Lois Delcambre, Anne-Francoise Le Meur, Ling Liu, David Maier, Dylan Mcnamee, Michael Miller, Calton Pu, Perry Wagle, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Some failures cannot be masked by redundancies, because an unanticipated situation occurred, because fault-tolerance measures were not adequate, or because there was a security breach (which is not amenable to replication). Applications that wish to continue to offer some service despite nonmaskable failure must adapt to the loss of resources. When numerous combinations of non-maskable failure modes are considered, the set of possible adaptations becomes complex. This paper presents adaptation spaces, a formalism for navigating among combinations of adaptations. An adaptation space describes a collection of possible adaptations of a software component or system, and provides a uniform way of …

Development And Validation Of A Work Safety Compliance Measure, Tara L. Smecko

Dissertations and Theses

It is important that organizations manage the safety behavior of employees by the implementation of a safety program including periodic assessment of the safety level (i.e., how frequently employees are complying with safety guidelines) in the organization. The occupational safety literature lacks sufficient assessment tools for measuring employee safety behavior.

The purpose of the present study was to develop and validate a comprehensive measure of compliance with safety behavior guidelines in the form of a questionnaire that can be utilized across industries and occupations. The research objectives for the present study were to: 1) Perform factor analysis on the safety …

Speech Intelligibility Of 4-Year-Old Children, M. Jane Firestone

Dissertations and Theses

While speech-language pathologists routinely measure and report speech intelligibility when assessing young children with speech impairments, normative data have not been available for comparison purposes. When assessing children to determine if their communication abilities are at or below that of peers, one must first know what the normative standards are. Knowing the normal distribution for speech intelligibility at several ages would allow for more precise uses of the intelligibility information than is currently possible. Only a few available studies exist to allow tentative normative comparisons of speech intelligibility data.

The goals of this pilot study were to collect normative data …

The Effectiveness Of Hypermedia Training Vs. Traditional Classroom Instruction In Stuttering, Micheal Dean Baran

Dissertations and Theses

A study by Henri (1994) showed that fluency is one of two areas where speech-language pathology clinicians feel least prepared and Sommers and Caruso (1995) advocated improved training in fluency. The use of computer technology to train students in the field of stuttering has been proven effective in previous studies (Strang, Meyers & Hall, 1989; Tetnowski & Martin, 1996).

The purpose of this study was to further develop a hypermedia training module for stuttering identification and to determine whether this hypermedia training module was as effective as traditional classroom teaching methods.

Subjects in this study were undergraduate students in speech …

Training For Volunteer Teachers In Church-Affiliated English Language Mission Programs, Janet Noreen Blackwood

Dissertations and Theses

There is currently a debate among language educators regarding the training and certification of EFL teachers. Largely ignored in this debate are short-term volunteer teachers in church-affiliated English language mission programs. These teachers fall somewhere on the continuum between untrained language teachers and trained professional language educators. The current study took place in response to the lack of research information available on this aspect of ESL/EFL teacher education.

This study focused on the training that is provided to volunteer ESL/EFL teachers affiliated with the Seventh-day Adventist (SDA) denomination. The four research questions sought to determine how the content and procedures …

Returning Women's Workshop And Retention Of Returning Women Students, Kimberly E. Lamb

Dissertations and Theses

This thesis investigates the retention of returning adult women students by examining: 1) demographic and motivational backgrounds of women who attend a university Returning Women's Workshop and women who do not; 2) retention, bonding, and support measures for the two groups of women; 3) student evaluations of the various Workshop components. The thesis also describes the history of the Workshop and the Women's Study Program.

A telephone survey was conducted of women who either participated in the Returning Women's Workshop or attended the University during the same selected years. All the women surveyed were over the age of 24 and …

The Representation Of Gender In Current Esl Reading Materials, Kyunghee Ma

Dissertations and Theses

This study is a partial replication of E.W. Hoomes' dissertation (1978). The purpose of this study is to investigate whether or not gender bias exists in current ESL reading materials and in cases where gender bias exists, whether it varies by learning levels. Eleven reading books which were used in ESL classes at Portland State University were selected from the textbook lists of Winter, Spring, Summer, and Fall in 1997. Content analysis was employed to examine distribution of males and females in passages and illustrations.

Gender bias was found to be statistically significant in the following categories: the assignment of …

Morphology, Eruption Rates, And Rheology Of Lava Domes: Insights From Laboratory Models, Jonathan H. Fink, Ross W. Griffiths

Geology Faculty Publications and Presentations

The growth of lava domes can be either quiescent or violent, with transitions between styles of behavior commonly occurring with little warning. Here we propose that the behavior depends on the eruption rate, the magma rheology, and the thickness ofthe cooling surface. We present a model, based on laboratory simulations, field measurements, and photographic analysis, that relates the morphology and texture of a dome to the thickness of its cooled carapace, and thence to eruption conditions. A sequence of four main types of dome (spiny, lobate, platy, and axisymmetric) is identified in laboratory analog experiments with a Bingham plastic. These …

The Impact Of Relative Gains On Interstate Cooperation In The Areas Of Security And International Economy, Renato Corbetta

Dissertations and Theses

In the last twenty years, the issue of the impact of relative gains on interstate cooperation has been at the center of the debate between the two major schools of thought in International Relations theory, namely neoliberalism and neorealism. Over time, the relative gains problem has ceased to be a radically divisive issue and has worked as a common research program that has brought the two theoretical perspectives closer together. Both neoliberals and neorealists have set aside major questions regarding the origins of the relative gains problem and of states' preferences, and they have focused on the problem of determining …

The Design Of Cube Calculus Machine Using Sram-Based Fpga Reconfigurable Hardware Dec’S Perle-1 Board, Qihong Chen

Dissertations and Theses

Presented in this thesis are new approaches to column compatibility checking and column-based input/output encoding for Curtis decompositions of switching functions. These approaches can be used in Curtis-type functional decomposition programs for applications in several scientific disciplines. Examples of applications are: minimization of combinational and sequential logic) mapping of logic functions to programmable logic devices such as CPLDs, MPGAs, and FPGAs, data encryption, data compression, pattern recognition) and image refinement. Presently, Curtis-type functional decomposition programs are used primarily for experimental purposes due to performance, quality, and compatibility issues. However) in the past few years a renewal of interest in the …

Reporting The Counterrevolution : The Sed Perception Of “Prague Spring” As Reported In Neues Deutschland January 1-August 21, 1968, Lee Allen Evans

Dissertations and Theses

In 1968, Czechoslovakia attempted to sweep the ashes of Stalinism from its path to socialism. The reform-movement "Prague Spring" united the nation with a goal to achieve a more just form of socialist society. When the Soviet Union and its Warsaw Pact allies invaded Czechoslovakia on August 21, 1968, they destroyed this dream.

The purpose of this thesis is to show how the SED interpreted events in Prague and presented their analysis to the East German public. Although imbedded in events in Czechoslovakia, this is an essay on German history.

The SED presented a public image of complete unity. The …

The Effect Of Diastema Closure On The Remediation Of Lateral /S/: A Case Study, Reta Price

Dissertations and Theses

An important morphological-marker and one of the most frequently occurring speech sounds in English, the /s/ phoneme is also one of the sounds most often in need of remediation. Often, air emission during /s/ production, a particularly stubborn, often residual production error, is not remediated through traditional treatment methods, and yet the negative effect /s/ distortions have on listeners has been well-documented.

The subject of this investigation was a forty-eightyear-old male who received treatment for a lateralized /s/ during grade-school. It was hypothesized that his exerting high anterior pressure to prevent air from escaping from a diastema between his two …

Effect Of Environmental Structure On Evolutionary Adaptation, Jeffrey Alan Fletcher, Mark A. Bedau, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper investigates how environmental structure, given the innate properties of a population, affects the degree to which this population can adapt to the environment. The model we explore involves simple agents in a 2-d world which can sense a local food distribution and, as specified by their genomes, move to a new location and ingest the food there. Adaptation in this model consists of improving the genomic sensorimotor mapping so as to maximally exploit the environmental resources. We vary environmental structure to see its specific effect on adaptive success. In our investigation, two properties of environmental structure, conditioned by …

Expanding And Sustaining Partnerships: Characteristics Of Successful University Community Partnerships, Judith A. Ramaley

Public Administration Faculty Publications and Presentations

The Community Outreach Partnership Centers (COPC) Program requires adaptations in the university environment. We must examine and reinterpret (1) the roles and responsibilities of faculty;(2) the design of the undergraduate curriculum; (3) the structures of the university that create the capacity and support to sustain different working relationships with the community; and (4) our definitions of success and quality.

Assessing Second Language Proficiency In An American University, Suwako Watanabe, Patricia Wetzel

World Languages and Literatures Faculty Publications and Presentations

There are currently two nation-wide trends that impinge significantly on language teaching and assessment at the university level in the U.S. One is the general wave of education reform, the other is the so-called "proficiency" movement in language teaching. That being said, these two categories are much too broad in their definitions and implications to be of any use in discussing what we wish to address here: actual practice in the second language classroom. We will therefore begin by constraining the relevant characteristics of each of these. We will then proceed to discuss their ongoing implications for what actually happens …

Sacagawea : The History Of A Myth, William Jeffrey Patten

Dissertations and Theses

Sacagawea, the Indian woman who accompanied the Lewis and Clark Expedition has been one of the most romanticized figures in Western history. Although Sacagawea received little attention following the Corps of Discovery's return to the United States, she was rediscovered by writers associated with the women's suffrage movement at the end of the nineteenth century. The development of the enduring American legend that formed around Sacagawea was an Anglo-American and twentieth century phenomenon. In myth, she was given credit for the success of the Lewis and Clark Expedition, and over time she became its savior and leader.

It is the …
