Continuous Deflection Separation Of Stormwater Particulates, Tracy S. Schwarz, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

Capture of stormwater particulate matter is of concern to watershed managers trying to meet water quality guidelines by removing toxics associated with particulates from natural water bodies. A laboratory investigation into particle removal efficiency of a prototype Continuous Deflective Separation (CDS) device was made in the laboratory. Particle size distributions were obtained for roadway drainage surfaces. These distributions were used to assess the predicted performance of a CDS unit in the field.

Flow rates in the laboratory tests ranged from 125 GPM (7.9 l/s) to 270 GPM (17.0 l/s). Screen sizes used for testing were 1200 m and 2400 m. …

Aquatic Vegetation In Irrigation Canals, Mark Sytsma, Michael Parker

Center for Lakes and Reservoirs Publications and Presentations

Preparation of this guidance manual for integrated aquatic vegetation management in irrigation canals was stimulated, in large part, by the accidental release of acrolein-treated irrigation water into Bear Creek in southern Oregon. The resulting fish kill brought into focus the need to examine the methods available for managing aquatic vegetation in flowing water. Furthermore, it demonstrated the need for technical assistance on aquatic vegetation management in Oregon. Vegetation management in flowing water is a difficult undertaking. The interconnectedness of natural and manmade water conveyance systems, the tenuous status of many aquatic species, and the necessity of water delivery for profitable …

Finding A Fit Between Work And Family Life: Support For Working Caregivers, Eileen M. Brennan, Julie M. Rosenzweig, Alice Myrth Ogilvie

School of Social Work Faculty Publications and Presentations

This article examines the ways in which families with employed caregivers and children with emotional and behavioral disorders manage to meet the demands of employment and family responsibilities. Finding a fit between the demands of work and family life is a struggle for every employed mother and father. For parents whose children have emotional, behavioral, or mental disorders, meeting this challenge can prove extremely stressful, particularly since supportive services are notably lacking. There has been little research on the perceptions of employed parents of children with mental health concerns about the ways in which work and family responsibilities can fit …

Archaeological Investigations At 45cl1 Cathlapotle (1991-1996) , Ridgefield National Wildlife Refuge Clark County, Washington: A Preliminary Report, Kenneth M. Ames, Cameron M. Smith, William L. Cornett, Elizabeth A. Sobel, Stephen C. Hamilton, John Wolf, Doria Raetz, United States. Department Of The Interior, U.S. Fish And Wildlife Service, Region 1, Portland State University. Department Of Anthropology

Anthropology Faculty Publications and Presentations

This is the preliminary report, one in a series on the archaeology of the Wapato Valley region of the Lower Columbia River. Most of the reports discuss aspects of the excavations and archaeology of two sites, the Meier site (35CO5) and Cathlapotle site (45CL1). Other related topics are also treated.

Archaeological investigations at site 45CL1, Clark County, Washington, demonstrate that the locality is a very large (c 1.5ha), deeply stratified (2-4m) town site with an occupation spanning at least 1000 years (c. AD 1000 to 1840). Six large, complex depressions have been mapped. Test excavations show that these depressions represent …

Identification Of Stuttering Moments: Is Hypermedia Training As Effective As Traditional Classroom Instruction?, Johna Delene Wakem

Dissertations and Theses

Significant deficits in clinical preparedness for fluency disorders and computer literacy have been identified through research. A hypermedia program that teaches students how to identify moments of stuttering could address both clinical preparedness issues and computer literacy. It is the purpose of this study to investigate the validity of a hypermedia program as a training tool. Twenty-one college students were divided into 2 groups based on scores from a pre-training assessment task. Group A attended traditional classroom lectures to learn the skill of stuttering identification, whereas Group B used the hypermedia program. All participants were given a post-training video assessment …

Cost-Benefit Analysis Of Physician Assistants, Roderick Stanton Hooker

Dissertations and Theses

This study examined if physician assistants (PAs) are cost-beneficial to employers. In an era of cost accountability, questions arise about whether a visit to a PA for an episode of care differs from a visit to a physician, and if PAs erode their cost-effectiveness by the manner in which they manage patients.

Four common acute medical conditions seen by PAs and physicians within a large health maintenance organization were identified to study. An episode approach was undertaken to identify all laboratory, imaging, medication and provider costs for these diagnoses. Over 12,700 medical office visits were analyzed and assigned to each …

Class Identity And The International Division Of Labor: Sri Lanka's Migrant Housemaids, Michele Ruth Gamburd

Anthropology Faculty Publications and Presentations

In 1996, 408,000 Sri Lankan women, nearly 10% of the country’s working-age women, worked abroad, many of them in the oil producing countries of the Persian Gulf. In this paper I compare the influence of international migration on local hierarchies of class and gender in two villages in southern Sri Lanka: a Sinhala-speaking Buddhist village where I did my doctoral dissertation research in 1992-4, and a Tamil-speaking Muslim village where I spent some time during the summer of 1997. I discuss the challenges of using ‘class’ as a unit of analysis in a non-Western setting where gender identities, family ties, …

Kennedy, 60 Minutes, And Roger Rabbit: Understanding Conspiracy-Theory Explanations Of The Decline Of Urban Mass Transit, Martha J. Bianco

Center for Urban Studies Publications and Reports

This paper will review the history of the GM Conspiracy Myth, as well as what legal theorists refer to as "the facts in the case." The legal explanation of what really happened goes only so far, though. The whole story about the decline of mass transit in the U.S. is a story about the failure of public policy and about conflict among competing constituencies in the transportation policy process. This paper will very briefly discuss this failure and this conflict and will then conclude with a consideration of - or at least a hypothesis for - the endurance of the …

Simple Model For Linear And Nonlinear Mixing At Unstable Fluid Interfaces With Variable Acceleration, John D. Ramshaw

Physics Faculty Publications and Presentations

A simple model is described for predicting the time evolution of the half-width h of a mixing layer between two initially separated immiscible fluids of different density subjected to an arbitrary time-dependent variable acceleration history a(t). The model is based on a heuristic expression for the kinetic energy per unit area of the mixing layer. This expression is based on that for the kinetic energy of a linearly perturbed interface, but with a dynamically renormalized wavelength which becomes proportional to h in the nonlinear regime. An equation of motion for h is then derived from Lagrange's equations. This model reproduces …

The Impact Of Congestion Pricing And Parking Taxes On Spatial Competition, Anthony M. Rufolo, Martha J. Bianco

Center for Urban Studies Publications and Reports

Policymakers seeking to reduce reliance on single-occupant automobiles are giving serious consideration to methods to price roads during periods of congest ion and to increase the cost of parking. Such policies are intended to induce increases in carpooling and in the use of mass transit; however, they may have unintended consequences that counteract these goals in the long run. In particular, actual implementation of such policies may create differential price increases that affect the spatial competition for markets between firms located in the central city and those in the suburbs. Analyzing such policies using the spatial competition models of location …

Marketing Central City Residence To An Aging Baby Boom: The Transportation Angle, Daphne Spain, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This paper proposes that the aging baby boom will contribute significantly to transportation problems in the future because 1) current land use patterns necessitate dependence on cars; and 2) aging baby boom women will drive more than elderly women do now. Policies that promote central city residence by stressing the transportation advantages of high-density living, therefore, should have particular appeal to baby boom women seeking prolonged independence. Such policies would also serve the interests of localities by reducing traffic congestion, pollution, and further sprawl. We suggest that a combination of direct and indirect housing policies comparable to those that financed …

The Politics Of Implementation: Oregon's Statewide Transportation Planning Rule - What's Been Accomplished, Martha J. Bianco, Sy Adler

Center for Urban Studies Publications and Reports

This paper is a case study of the evolution of Oregon’s groundbreaking Transportation Planning Rule, from its adoption in 1991, up through present amendments. Our analysis is an assessment of how private- and public-sector investors grapple with the coproduction of the built environment under the constraints of a value system that emanates from the state, shepherded by litigious public interest groups. In this case, this value system is articulated in the Oregon administrative rule known as the Transportation Planning Rule. This Rule emphasizes a reduction in the reliance on automobiles and, among other things, requires a decrease in vehicle miles …

The Connection Between Public Transit And Employment, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

Even with a considerable amount of attention being paid to the role of public transportation in addressing inner-city mobility problems, there is very little evidence of the degree to which one affects the other. In other words, little research has specifically focused on how labor participation is impacted by increases in public transportation availability. Research on the spatial mismatch hypothesis has dealt with the relationship between labor participation and the spatial separation of jobs and houses; however, most analyses concentrate on commuting time or distance as a function of auto accessibility. Few, if any, studies have considered the relative impacts …
