Categories And Similarities: A Note On Circularity, L. David Ritchie

Communication Faculty Publications and Presentations

Theories of metaphor comprehension that rely on category assignment based on common characteristics (Keysar & Glucksberg, 1992), a comparison between characteristics or relationships of source and target (Chiappe & Kennedy, 2001), or a mapping of characteristics or relationships from source to target (Gentner & Bowdle, 2001) are inherently circular, since these comparisons, mappings, or categories usually make sense only after the underlying metaphor has already been understood. This inherent circularity is avoided by approaches such as conceptual metaphor theory (Lakoff & Johnson, 1980) and conceptual blending theory (Fauconnier & Turner, 1998) that seek to explain metaphors in terms of underlying …

Statistical Probability As A Metaphor For Epistemological Probability, L. David Ritchie

Communication Faculty Publications and Presentations

The metaphor, "epistemological probability is statistical probability" is traced to the origins of probability theory. Related metaphors appear both in everyday discourse about social processes, and in social scientific argumentation, often disguised as literal claims. Gambling provides a familiar vehicle for expressing the uncertainties associated with social interactions, and with social science research. Examples are drawn from reports of research on media effects, from everyday conversations, and from political communication.

Subglacial Thermal Balance Permits Ongoing Grounding Line Retreat Along The Siple Coast Of West Antarctica, Byron R. Parizek, Richard B. Alley, Christina L. Hulbe

Geology Faculty Publications and Presentations

Changes in the discharge of West Antarctic ice streams are of potential concern with respect to global sea level. The six relatively thin, fast-flowing Ross ice streams are of interest as low-slope end-members among Antarctic ice streams. Extensive research has demonstrated that these "rivers of ice" have a history of relatively high-frequency (óO(100) years), asynchronous discharge variations with evolving lateral boundaries. Amidst this variability, a ~1300 km grounding-line retreat has occurred since the Last GlacialMaximum. Numerical studies of Ice Stream D (Parizek and others, 2002) indicate that a proposed thermal-regulation mechanism(Clarke and Marshall, 1998; Hulbe and MacAyeal,1999; Tulaczyk and others, …

Transportation And Land Use Patterns: Monitoring Urban Change Using Aerial Photography, Portland, Oregon 1925-1945, Paul Hagen Fyfield

Dissertations and Theses

American urban neighborhoods are a patchwork; the spatial arrangement of types is a reflection of the dominant transportation technology at the time of their development. The earliest suburban areas were made accessible by fixed route systems such as the electric streetcar, followed by the widespread adoption of the automobile; each transportation epoch resulted in characteristic patterns of land use. This study uses aerial photographic coverage of Portland, Oregon from the years 1925, 1936, and 1945, a time of decline for the once popular trolley lines and dramatic increase in automobile usage, to monitor change within the residential areas of Portland's …

Multicultural Assessment: Research, Training, And Practice, Richard H. Dana

Regional Research Institute for Human Services

The credibility of standard assessment has been questioned by intra-professional debate, diminished by training deficits, redefined as semi-skilled technology by managed care, and compromised for multicultural populations by research bias. Scientific psychology has been responsible for perpetuation of bias and the limited generality of published ethnic minority research. A constructive response to these issues includes more coherent scientific preparation for assessment practice, particularly with ethnic minority populations. Adequate preparation entails careful reformulation of assumptions, redefinition of variables, informed selection of research methodologies, understanding deficiencies in normative data, and using culturally responsible interpretive strategies with standard test data in addition to …

Educating The Guess: Strategies, Concepts And Tools For The Fuzzy Front End Of Product Development, Antonie J. Jetter

Engineering and Technology Management Faculty Publications and Presentations

Many companies lack efficient management of the early phases of new product development (NPD) - the socalled fuzzy front end (FFE). Rather than on structured methods, decision makers rely on ?gut ?feel? or ?guessing?. In an attempt to ?educate the guess? this paper discusses the activities and challenges of the FFE, as well as strategies to manage them successfully. It then briefly presents traditional and recent approaches to front-end management support. Based on the identified strengths and weaknesses of existing front-end solutions, the framework of a new management support system for the FFE is presented. Conceptually, the system is based …

A Tale Of Two Conferences – Cuba Style, Gretta E. Siegel

Library Faculty and Staff Publications and Presentations

The past few years have seen a marked increase in the level of interest about libraries in Cuba. Twelve years ago, a rare glimpse was given in an American Libraries article which piqued some peoples interest, but travel restrictions at that time left many interested in visiting but having no way to do so. However, a relaxing of travel restrictions under the Clinton administration permitted "people to people" and cultural exchanges, thus allowing more people to get a look at this country through formal tours. Several successful library tours were organized and led by people such as Rhonda Neugebauer from …

Self-Management And Social Skills Training For Persons With Developmental Disabilities: Tools For The Rehabilitation Counselor To Facilitate Success In Community Settings: A Literature Review, Tina M. Anctil Peterman, Charles Edmund Degeneffe

Counselor Education Faculty Publications and Presentations

People with developmental disabilities often display deficiencies in self-management and social skills in community based settings. Difficulties with self-management and social skills tend to pose particular difficulties for performing valued adult roles. Tools from behavior therapy have the potential to assist rehabilitation counselors in their work with consumers with developmental disabilities to overcome the negative impacts of functional limitations on expressing behaviors needed for success in community-based settings. This article presents a review of the behavior therapy literature regarding self-management and social skills training techniques rehabilitation counselors can use in their work with consumers with developmental disabilities in areas including …

"Argument Is War"-Or Is It A Game Of Chess? : Multiple Meanings In The Analysis Of Implicit Metaphors, L. David Ritchie

Communication Faculty Publications and Presentations

Both Lakoff and Johnson (1980) and Vervaeke and Kennedy (1996), in their critique of Lakoff and Johnson, drew narrowly from a broad range of reasonable interpretations of the metaphors they analyzed. Expanding the interpretations vitiates many of Vervaeke and Kennedy's criticisms, but it supports their call for an open interpretation of groups of metaphors and points toward a more complex elaboration of the theories put forth by Lakoff and Johnson. The results of applying this approach to "ARGUMENT IS WAR" suggest that war is not necessarily the primary conceptual metaphor for contentious argument, as Lakoff and Johnson claimed. Rather, there …

Beavers, Firs, Salmon, And Falling Water: Pacific Northwest Regionalism And The Environment, William L. Lang

History Faculty Publications and Presentations

Discusses the importance of salmon in defining environmental understanding in the Pacific Northwest. Dam construction, population influx, economic development, and politics have dramatically changed the geography of Oregon Country since 1850. The technological alterations and population growth redefined the sense of place. However, salmon has remained the most important icon of the Pacific Northwest, both for Native Americans and for nonnatives have who worked to save the salmon from extinction. Salmon have become a "living metaphor" for the region, and their fate reflects an understanding of historical context and the role of people in their relationship to the environment in …

Fergie's Prescience: The Changing Nature Of Diglossia In Tunisia, Keith Walters

Applied Linguistics Faculty Publications and Presentations

Despite criticisms it has received, Ferguson's (1959b) account of diglossia should be recognized for its prescience. It offered not only an admittedly idealized characterization of diglossia in Arabic, but also pointed out how and why it might change. Focusing on Tunisia, this article demonstrates the many ways in which Fergie was right. It examines the changing demographics of Tunisians' access to the high variety of Arabic; the complex ways in which Tunisians, and Arabs more generally, deal with the "communicative tensions" diglossia creates; and considers the changing nature of Arabic in what is, in many ways, a postdiglossic Tunisia.

The Interactive Work Of Prosody In The Irf Exchange: Teacher Repetition In Feedback Moves, John Hellermann

Applied Linguistics Faculty Publications and Presentations

This article examines the interactive import of prosody from a perspective of participants' orientation to talk in interaction, taking advantage of data from institutional discourse to focus on the prosodic packaging of recurring turn sequences of the same discourse activity. The analysis focuses on the third slot of a ubiquitous three-part classroom discourse sequence, the IRF exchange (Sinclair & Coulthard 1975), a site in which teachers make repetitive feedback moves following student responses. Examination of more than 25 hours of classroom discourse and more than 300 third-turn teacher feedback types uncovered a systematic use of prosody for these teacher repetitions …

Headway Deviation Effects On Bus Passenger Loads: Analysis Of Tri-Met’S Archived Avl-Apc Data, James G. Strathman, Thomas J. Kimpel, Steve Callas

Center for Urban Studies Publications and Reports

In this paper we empirically analyze the relationship between transit service headway deviations and passenger loads, using archived data from Tri-Met’s automatic vehicle location and automatic passenger counter systems. The analysis employs two-stage least squares estimation to account for the simultaneous relationship between headway deviations and loads. Controlling for the effects of passenger activity on delay, the results indicate that the observed incidence of excess passenger loads is systematically attributable to deviations from scheduled headways. In turn, analysis of the causes of headway deviations served to identify possible operations control actions that would improve service regularity and, consequently, reduce incidences …

Investigating The Urban Heat Island Effect With A Collaborative Inquiry Project, Linda Acha George, William G. Becker

Environmental Science and Management Faculty Publications and Presentations

Modification of the earth's surface through urbanization can have a dramatic impact on local climate. A phenomenon known as the Urban Heat Island (UHI) effect, which is a measure of the near-surface air temperature contrast between urbanized and adjoining rural areas, can be evaluated with readily available instruments. Students in an undergraduate general education science course study this phenomenon in the Portland, Oregon area through a collaborative research project. This inquiry project includes background content and literature review, preliminary studies, development of research questions, experimental design and implementation, data analysis and report writing. This project successfully enables students to collaboratively …

Evolution As Learning Yields Hyperbolic Discounting, James Woods

Economics Faculty Publications and Presentations

Learning is modeled as an infection, which jumps from person to person. The rate of infection mimics individual discount rates and induces savings behavior on its own. It is shown that the apparent discount rate, the combination of the agents’ true discount rate and the infection rate, decreases over time and approaches the agents’ true discount rate. This decrease, known as hyperbolic discounting, is consistent with what is observed in psychology studies, while the limiting case, exponential discounting, is consistent with market level observations. This model closes the gap between individual and market level observations of discounting behavior without explicitly …

Hosford-Abernethy Bicycle And Pedestrian Connections: An Alternative Routes Analysis Linking Se Clinton Street And The Eastbank Esplanade, Shannon Axtell, Evan Mackenzie, Brady Smith, Allison Wildman

Master of Urban and Regional Planning Workshop Projects

SE Clinton is a popular bicycle route for commuter, utilitarian and recreational bicyclists that fails to provide a safe and direct connection to the Eastbank Esplanade and downtown Portland. Furthermore, residents in the Hosford-Abernethy and Brooklyn neighborhoods do not have a safe bicycle and pedestrian connection to access the Eastbank Esplanade. This gap in the bicycle and pedestrian network must be removed to serve the needs of bicyclists and pedestrians.

This project presents four alternative bicycle and pedestrian routes that connect the Eastbank Esplanade and the SE Clinton bikeway through the Central Eastside Industrial District. Each alternative, with improvements, is …

High Frequency Pure Tone Audiometry And High Frequency Distortion Product Otoacoustic Emissions: A Correlational Analysis, Kimberly J. Lavoie

Dissertations and Theses

Previous studies show that pure tone thresholds are strongly correlated with distortion product otoacoustic emission amplitudes when evaluating the frequency range from 1 to 8 kHz (Avan & Bonfils, 1993). Little is known about correlations between these two measures at higher frequencies from 9-16 kHz. This study compared pure tone thresholds and distortion product otoacoustic emissions (DPOAEs) in this high frequency range for 29 normal hearing subjects ages 18-30. Pure tone thresholds were obtained at 250-16 kHz and distortion product otoacoustic emissions (DPOAE) 2,211-17,675 were measured in the same ears. DPOAE amplitudes were measured using a constant F1/F2 ratio of …

Setting The Pace: Model Inclusive Child Care Centers Serving Families Of Children With Emotional Or Behavioral Challenges, Eileen M. Brennan, Jennifer R. Bradley, Shane Ama, Natalie Diane Cawood

School of Social Work Faculty Publications and Presentations

Approximately 10% of American children experience an emotional or behavioral disorder that causes some level of impairment in their development, learning, or functioning in daily life, and the numbers of those affected appear to be growing (U.S. Public Health Service, 2000). With the entry of many family caregivers into the workforce, increasing numbers of children with these challenges are enrolling in child care settings that offer services to infants, toddlers, young children, or school aged youth (Shonkoff & Phillips, 2000). Child care settings can provide a unique opportunity to address the needs of children with emotional or behavioral challenges and …

The Strategy Of Sustainability: A Systems Perspective On Environmental Initiatives, Scott Marshall, Darrell Brown

Business Faculty Publications and Presentations

The article presents a systems perspective on environmental initiatives as they relate to the efforts of firms looking to become environmentally sustainable. To achieve environmental sustainability, firms need to implement principles, policies, and practices (such as budgeting systems, job design, recruitment and selection, and organizational structures) from the standpoint of long-term ecosystem viability. Because this process requires firms to establish challenging goals, managers are often confronted with significant conflicts between the financial and the environmental and social considerations when introducing socially or environmentally oriented decision making. The author recommends the adoption of a commonly shared corporate vision to allow for …
