Spontaneous Mode Locking In Mixed-Broadened Laser Oscillators, Pitak Chenkosol, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A theoretical model is reported for spontaneous mode locking in mixed-broadened laser oscillators. Experimental observations of this effect have been available for many years, but no rigorous interpretation has been given. Numerical calculations emphasize the case of a high-gain xenon laser, for which extensive experimental data have been published. Complex pulsation characteristics are observed as the cavity length and pumping rate are varied, and the theoretical results are in good agreement with the experimental data.

A Bridge To Coordination Isomer Selection In Lanthanide(Iii) Dota-Tetraamide Complexes, Jeff Vipond, Mark Woods, Piyu Zhao, Gyula Tircsó, Jimin Ren, Simon G. Bott, Doug Ogrin, Garry Kiefer, Zoltan Kovacs, A. Dean Sherry

Chemistry Faculty Publications and Presentations

Interest in macrocyclic lanthanide complexes such as DOTA is driven largely through interest in their use as contrast agents for MRI. The lanthanide tetraamide derivatives of DOTA have shown considerable promise as PARACEST agents, taking advantage of the slow water exchange kinetics of this class of complex. We postulated that water exchange in these tetraamide complexes could be slowed even further by introducing a group to sterically encumber the space above the water coordination site, thereby hindering the departure and approach of water molecules to the complex. The ligand 8O₂-bridged-DOTAM was synthesized in a 34% yield from cyclen. …

Culture War: The Battle For Portland's Lair Hill Neighborhood, 1968, James Tucker Jackson

Dissertations and Theses

The youth explosion of the mid-1960s that spawned the hippie counterculture also bred fear among older Americans, many of whom viewed the cultural dissenters as immoral, deviant, and criminal. Some in the ranks of government shared this view and felt duty-bound to oppose the counterculture. This thesis examines one example of a municipal government and the series of policies it pursued to address the threat of a "hippie invasion" into the Lair Hill neighborhood in Portland, Oregon in 1968. The central question will be to determine whether these policies were enacted in pursuit of the stated goals of improved public …

An Examination Of Faculty Experiences With Hybrid Formats, Jo Elsa Meyertons

Dissertations and Theses

This phenomenological study investigated the experiences of a set of faculty who taught classes in hybrid format at a small liberal arts university in Salem, Oregon. For this study, a "hybrid format" course was defined as a course that includes elements of both traditional face-to-face and technology-enhanced (often Internet) course components. The study consisted of a set of heuristic interviews with faculty members identified through an empirical survey I conducted in Fall 2002 as part of my duties as Director of Instructional Design and Development for the university's technical services department.

A Preliminary Proposal For The Development Of A Distance Education Lubrary Media Endorsement Program At Central Washington University, Marwin Britto

Northwest Journal of Teacher Education

In Washington State, there are currently six higher education institutions which offer state-approved library media endorsement programs for certified K-12 teachers. Due to population and geo graphical factors, our institution, Central Washington University, finds it difficult to attract K-12 teachers during non-summer months. Currently, our library media program is only offered during the summer months. Consequently, we lose a lot of the potential market of those unavailable during the summers. With the growing demand for library media specialists throughout Washington K-12 school districts, the timing may not be better in developing and implementing a fully distance education (DE) model for …

Out Of The Cabbage Patch, Gary R. Brown

Office of Academic Innovation Publications

It is not a secret to readers of EDUCAUSE Review that the challenge of curricular relevance and student engagement in higher education is a national concern. One aspect of this challenge is that students' social networking and technology proclivities are rarely met by conventional curricula and pedagogies. Educators have much to lose if we fail to transform current practice. Just how much we have to lose was profoundly illustrated to me on a recent trip I took to Malawi, Africa, where a group of educators and an affiliate non-governmental organization (NGO) have been working to expand opportunities for Washington State …

Advancing Transdisciplinary And Translational Research Practice: Issues And Models Of Doctoral Education In Public Health, Linda Neuhauser, Dawn M. Richardson, Sonja Mackenzie, Meredith Minkler

Community Health Faculty Publications and Presentations

Finding solutions to complex health problems, such as obesity, violence, and climate change, will require radical changes in cross-disciplinary education, research, and practice. The fundamental determinants of health include many interrelated factors such as poverty, culture, education, environment, and government policies. However, traditional public health training has tended to focus more narrowly on diseases and risk factors, and has not adequately leveraged the rich contributions of sociology, anthropology, economics, geography, communication, political science, and other disciplines. Further, students are often not sufficiently trained to work across sectors to translate research findings into effective, large-scale sustainable actions. During the past 2 …

Making Connections Beyond The Choir, David Johns

Political Science Faculty Publications and Presentations

Conservationists rely heavily on support from sectors of the population that want wildlife and wild places protected, but for whom it is not a priority. Support for conservation is widespread but not deep and seems to be weakening. This must be changed. Some of the obstacles are material—such as, fewer people have spent any part of their childhood immersed in nature. But many of the obstacles to deepening support among various constituencies rests with conservationists' prejudices: a belief that if people know the facts they will do the right thing; that truth by itself can overcome propaganda; that people are …

Using Simulation To Evaluate Global Software Development Task Allocation Strategies, Siri-On Setamanit, Wayne Wakeland, David Raffo

Complex Systems Faculty Publications and Presentations

We describe a hybrid computer simulation model of the software development process that is specifically architected to study alternative ways to configure global software development (GSD) projects, including phase-based, module-based, and follow-the-sun allocation strategies. The model is a hybrid system dynamics and discrete-event model. In this paper, test cases have been developed for each allocation strategy, and project duration is computed for each configuration under a range of plausible assumptions for key parameters. The primary finding is that although under ideal assumptions follow-the-sun is able to produce impressive reductions in time-to-market, under more realistic assumptions the reverse is true, thus …

Estimating Nutrient Uptake By Mature Tree Roots Under Field Conditions: Challenges And Opportunities, Melissa S. Lucash, Dave M. Eissenstat, J. Devereux Joslin, Karis J. Mcfarlane, Ruth D. Yanai

Environmental Science and Management Faculty Publications and Presentations

Nutrient uptake by roots of mature trees is difficult to measure accurately under field conditions using existing methods. In this review, we discuss current techniques for measuring uptake at the root surface including excised roots, isotopic tracers, autoradiography, depletion, and lysimeters. Although these methods have provided many insights, each has drawbacks. Estimates of uptake are affected by the sampling scheme, experimental conditions, whether roots are excised or not, concentrations of ions, and the rate of efflux of ions. Microbes and mycorrhizas can also affect estimates of uptake. A greater focus on methods development is critical to advancing our understanding of …

Indigenous Scientific Literacies In Nalo Hopkinson’S Ceremonial Worlds, Grace L. Dillon

Indigenous Nations Studies Faculty Publications and Presentations

Increasingly our critical tradition is recognizing the prevalence of issues of indigeneity in sf. Whether this emerging emphasis reflects keener powers of observation on the part of readers or shifting preferences on the part of writers, it is clear that, as the idealism of a Golden Age melts into the dross of colonial aftermath, sf is beginning to reflect the West's rising awareness that manifest destinies, whatever fashion they wear, wield a violent science in pursuing control and care little for the cultures they displace and erase. Nor is it surprising that a genre noted for its pioneering exploration of …

Educational Achievement: Shaping The Region's Reputation And Driving Its Economy, John Tapogna

Institute of Metropolitan Studies Publications

Any region’s reputation in education is a key to its economic vitality. Businesses look for signals of a quality workforce. Families want good schools for their children. The Portland-Vancouver region is making progress in education, but the news is not uniformly good. On the positive side, Portland is rising in the ranks of so-called “well educated” cities—a reputation that benefits the region as a whole. Portland’s attractiveness to young, recent college graduates is well documented and has played an important role in the trend. The influx of young professionals is a plus for the regional economy. However, instability of K-12 …

Tienen Ventajas Cognitivas Los Bilingües Sobre Los Monolingües?, Eva NúÑEz-MéNdez

World Languages and Literatures Faculty Publications and Presentations

Desde comienzos del s. XIX hasta aproximadamente los años 60, se creía entre los investigadores que el bilingiüsmo resultaba perjudicial para el pensamiento, ya que provocaba la reducción por la mitad no sólo del desarrollo intelectual sino también del espiritual. Esta ideología se ha extendido ampliamente en los EEUU en el s. XX: el bilingüismo trae consigo más desventajas que beneficios en términos de cognición. El bilingüismo se presenta como una carga sobre el cerebro, provocando confusión mental, inhibición de la lengua mayoritaria, e incluso división de la personalidad.

Bleeding Albina: A History Of Community Disinvestment, 1940‐2000, Karen J. Gibson

Urban Studies and Planning Faculty Publications and Presentations

Portland, Oregon, is celebrated in the planning literature as one of the nation’s most livable cities, yet there is very little scholarship on its small Black community. Using census data, oral histories, archival documents, and newspaper accounts, this study analyzes residential segregation and neighborhood disinvestment over a 60-year period. Without access to capital, housing conditions worsened to the point that abandonment became a major problem. By 1980, many of the conditions typically associated with large cities were present: high unemployment, poor schooling, and an underground economy that evolved into crack cocaine, gangs, and crime. Yet some neighborhood activists argued that …

The Preservation Perplex: Finding The Balance Between Our Past And Future, Elizabeth Mylott

Institute of Metropolitan Studies Publications

James Conway’s September 2005 description of Portland in Preservation typifies the city’s image as a place where innovative planning has created an exceptional and impressive urban landscape. Portland prides itself on being uniquely livable. Known for clean streets, urban parks and a laid back lifestyle, for many it’s the very model of a successful city. Public transportation is widely used, the city’s downtown remains vibrant, and smaller neighborhood commercial centers provide big draws for shopping and entertainment. Local natural amenities are widely enjoyed, as residents fl ock to urban parks and natural areas outside the city. As a result, the …

Locally Conservative Fluxes For The Continuous Galerkin Method, Bernardo Cockburn, Jay Gopalakrishnan, Haiying Wang

Mathematics and Statistics Faculty Publications and Presentations

The standard continuous Galerkin (CG) finite element method for second order elliptic problems suffers from its inability to provide conservative flux approximations, a much needed quantity in many applications. We show how to overcome this shortcoming by using a two step postprocessing. The first step is the computation of a numerical flux trace defined on element inter- faces and is motivated by the structure of the numerical traces of discontinuous Galerkin methods. This computation is non-local in that it requires the solution of a symmetric positive definite system, but the system is well conditioned independently of mesh size, so it …

No Law: Deadwood And The State, Mark L. Berrettini

School of Film Faculty Publications and Presentations

Deadwood's final episode of season 3 opens with a monologue from theater operator Jack Langrishe (Brian Cox), a relative newcomer to the camp of Deadwood. Shown in a wide shot that spotlights him on the dark stage of his nascent theater, Langrishe ostensibly speaks to one of his companions, the actress Claudia (Cynthia Ettinger), shown in one medium reverse-shot. Yet Langrishe also speaks and performs beyond the theater to the residents of Deadwood and to the program's viewers extradiagetically as he sums up the tense state of affairs within the camp: This camp is in mortal danger. The man Hearst …
