Identifying Models Of Obsidian Distribution In Preclassic Maya Lowlands Contexts, Sabine Tischler

University Honors Theses

Obsidian was an important resource throughout Mesoamerica, and found at nearly all sites. Sources of obsidian were located in the Mexican Highlands and Guatemalan Highlands, often being transported over hundreds of kilometers for distribution. In this paper I chose four Maya sites--El Ceibal, Tikal, Xtobo, and Actun Uayazba Kab--and used three obsidian distribution models previously published by De León et al. in 2009, to infer possible distribution methods used in the Maya Lowlands. Though limitations existed the results from this proof-of-concept analysis indicate that distribution models derived for central Mexican contexts are suitable for Maya regions, and that the Maya …

Get Connected: Lessons Shared From The Pnw-Garlic Mustard Working Group, Michelle Delepine

Urban Ecosystem Research Consortium of Portland/Vancouver

Garlic mustard (Alliaria petiolata) is an ODA-listed class B noxious weed and threatens many types of ecosystems west of the Cascade Range, as well as riparian corridors east of the Cascades. Starting in 2014, a self-organized collaboration called the Pacific Northwest Garlic Mustard Working Group has brought together invasive plant managers from across Oregon, Washington, and British Columbia to share observations, best management practices, prevention techniques, survey methodologies and outreach strategies across the region. This has resulted in developing shared outreach and prevention products, a cross-jurisdictional Integrated Pest Management (IPM) strategy, regional maps, and a collaborative understanding of management practices …

California Groundwater Management, Science-Policy Interfaces, And The Legacies Of Artificial Legal Distinctions, David Owen, Alida Cantor, Nell Green Nylen, Thomas Harter, Michael Kiparsky

Geography Faculty Publications and Presentations

California water law has traditionally treated groundwater and surface water as separate resources. The 2014 Sustainable Groundwater Management Act (SGMA) broke with this tradition by requiring groundwater managers to avoid significant and unreasonable adverse impacts to beneficial uses of surface water. This paper considers the trajectory of this partial integration of science, law, and resource management policy. Drawing on legal analysis and participatory workshops with subject area experts, we describe the challenges of reconciling the separate legal systems that grew out of an artificial legal distinction between different aspects of the same resource.

Our analysis offers two main contributions. First, …

Healthcare Spending Mandate Modeling Report, Northwest Economic Research Center, Peter Hulseman, Adam Rovang, Devin Bales, Nicholas Chun

Northwest Economic Research Center Publications and Reports

Governor Brown’s health care financing package, which was released with the 2019-21 recommended budget included several revenue components which provide broad-based, sustainable revenue for health care coverage in Oregon for the next six years. One component of that package is the Subsidized Employer Participation Program, which would be similar to the San Francisco Health Care Security Ordinance (HCSO). The new requirement would compel employers of a certain size who otherwise do not qualify for any exemption to contribute to their employees’ health care costs. An employer’s contribution could be in one of three ways: (1) in the form of directly …

Addressing Changing Demographics In Environmental Justice Analysis, State Of Practice, Aaron Golub, Les Brown, Michael Grant, Nathan Mcneil, Charles Ryerson, Matt Gray, Stephanie Lonsdale, Madison Levy

TREC Final Reports

This report documents how metropolitan planning organizations (MPO), State departments of transportation (DOT), and other transportation agencies are adapting Environmental Justice (EJ) analysis techniques to understand transportation impacts in communities undergoing rapid demographic change. The report also highlights national demographic trends, showing significant change in the size and location of low-income and minority households. These changes are documented in a series of State- and county-level maps demonstrating absolute and percent change in minority populations, low-income populations and limited English proficiency populations between the 1990 – 2010 decennial census periods. Based on the state of practice review, the report also highlights …

Appetite For Growth: Challenges To Scale For Food And Beverage Makers In Three Us Cities, Greg Schrock, Marc Doussard, Laura Wolf-Powers, Steven Marotta, Max Eisenburger

Urban Studies and Planning Faculty Publications and Presentations

Food and beverage (FaB) manufacturing represents a promising opportunity for small-scale “makers” and local economic development. The growth of entrepreneurial maker businesses can be understood in terms of segmentation of market demand, emergence of new intermediaries, and availability of affordable production infrastructure. Yet the ease of starting maker businesses stands in contrast with the challenges of achieving growth and scale as a manufacturer. Through semistructured interviews with 31 FaB makers in Chicago, New York City, and Portland, Oregon, the authors analyze the challenges facing maker–entrepreneurs in this sector. The authors find that the everyday character of food and the relative …

Spatial Analysis Of Landscape And Sociodemographic Factors Associated With Green Stormwater Infrastructure Distribution In Baltimore, Maryland And Portland, Oregon, Ashley Baker, Emma Brenneman, Heejun Chang, Lauren Mcphillips, Marissa Matsler

Geography Faculty Publications and Presentations

This study explores the spatial distribution of green stormwater infrastructure (GSI) relative to sociodemographic and landscape characteristics in Portland, OR, and Baltimore, MD, USA at census block group (CBG) and census tract scales. GSI density is clustered in Portland, while it is randomly distributed over space in Baltimore. Variables that exhibit relationships with GSI density are varied over space, as well as between cities. In Baltimore, GSI density is significantly associated with presence of green space (+), impervious surface coverage (+), and population density (−) at the CBG scale; though these relationships vary over space. At the census tract scale …

Community-Engaged Teaching: Lessons From A Participatory History Project, Amie Thurber, Sarah V. Suiter

School of Social Work Faculty Publications and Presentations

How can we create opportunities for students to gain experience in community-engaged scholarship that truly benefits the community given the constraints of the academic calendar, students’ varied capacity to develop reciprocal and responsive community relationships, and the tendency for community-engaged research to instrumentalize community partners in service to academic deliverables? This paper explores one attempt to meet this challenge: an experimental graduate course in community development that linked course content to a participatory history project. Designed as a Scholarship of Teaching and Learning (SoTL) study, instructors studied the instructional process as well as outcomes for students and community partners. We …

Latent Space Models For Temporal Networks, Jasper Alt

Systems Science Friday Noon Seminar Series

In many contexts we may expect the structure of networks to be derived from some kind of abstract distance between actors. We refer to this phenomenon as homophily: like nodes connect to like. For example, people with similar beliefs may be more likely to form social relations.

We formalize this notion by positioning the nodes in a latent space representing the possible values of the homophilous attributes. Realistically, we should expect latent attributes like beliefs to change over time in some nontrivial way, and the structures of temporal networks to evolve accordingly. We introduce a model of latent space dynamics …

Recognizing And Addressing Risk Ambiguity In Sea Level Rise Adaptation Planning: A Case Study Of Miami-Dade County, Florida, Mary Ann Rozance

Dissertations and Theses

As coastal cities around the world identify and implement adaptations to sea level rise, they are faced with competing interests around what should be done and how to prioritize actions. Often, environmental problems--like confronting the challenge of sea level rise--are posed as requiring expert driven, technical solutions to identify and mitigate risks across the landscape. This framing, however, ignores the way in which diverse knowledge can help inform long-term planning horizons that address complex ways that sea level rise affects communities. The failure to integrate diverse knowledge into sea level rise adaptation can result in barriers to implementation and outcomes …

Evaluating The Impact And Distribution Of Stormwater Green Infrastructure On Watershed Outflow, Benjamin Fahy

Dissertations and Theses

Green Stormwater Infrastructure (GSI) has become a popular method for flood mitigation as it can prevent runoff from entering streams during heavy precipitation. In this study, a recently developed neighborhood in Gresham, Oregon hosts a comparison of various GSI projects on runoff dynamics. The study site includes dispersed GSI (rain gardens, retention chambers, green streets) and centralized GSI (bioswales, detention ponds, detention pipes). For the 2017-2018 water year, hourly rainfall and observed discharge data is used to calibrate the EPA's Stormwater Management Model to simulate rainfall-runoff dynamics, achieving a Nash-Sutcliffe efficiency of 0.75 and Probability Bias statistic of 3.3%. A …

Social Equity In Transit Service: Toward Social And Environmental Justice In Transportation, Torrey Lyons

TREC Theses and Dissertations

This dissertation explores social equity as it applies to public transportation. Transit has long been considered a tool to alleviate inequity by limiting the effects of spatial mismatch and providing access to opportunity to disadvantaged populations. This theory, however, has not been adequately proven empirically. The first chapter of this dissertation tests the theory that spatial mismatch is moderated by quality transit service. We do this by taking a cross section of the largest urban areas in the United States and applying structural equation modeling to identify relationships between exogenous and endogenous factors. We find that higher quality transit service …

Plea Bargaining: The Influence Of Counsel, Kelsey S. Henderson, Lora M. Levett

Criminology and Criminal Justice Faculty Publications and Presentations

For the criminal defendant, his attorney acts as his loyal and zealous advocate before the court (American Bar Association, 2015), and due process protections of the U.S. adversarial system have afforded this relationship special privilege. In this chapter, we explore the influence and role of the attorney in plea decision making. We first explore the legal context of the attorney’s role in plea bargaining, reviewing several cases that address a defendant’s right to effective assistance of counsel. We then review the shadow of trial theory and other theoretical perspectives as they relate to the attorney’s role in the plea-bargaining process, …

Changes In Farmland Ownership In Oregon, Usa, Megan Horst

Urban Studies and Planning Faculty Publications and Presentations

The ownership of agricultural land has important implications for food systems, the environment, farmer livelihoods, and rural economies, communities, and landscapes. This article examines the changing ownership of agricultural lands in the United States, specifically focusing on Oregon, a state with a history of family farm ownership. I first review historical and recent trends in farmland ownership, including private enclosure, consolidation, investor purchase, development, and rising farmland prices. Next, I examine the county records for all Oregon farm properties that sold between 2010 and 2015. I provide summary statistics about the volume and pace of transactions, price per acre, and …

Raven’S Work In Tlingit Ethno-Geography, Thomas F. Thornton, Douglas Deur, Bert Adams

Anthropology Faculty Publications and Presentations

This is a chapter in Language and Toponymy in Alaska and Beyond: Papers in Honor of James Kari.

Book description:
It is difficult to imagine place names research in Alaska without the work of James Kari. Through his tireless field work and advocacy, Dr. Kari has collaborated with speakers of all of Alaska’s Dene languages to help build a comprehensive record of Dene geographic knowledge. When Jim came to Alaska in 1972, the documentation of Dene languages was fragmentary at best, and the only records of Native place names were those found inaccurately spelled on maps and gazetteers. Now …

Reorientations; Or, An Indigenous Feminist Reflection On The Anthropocene, Kali Simmons

Indigenous Nations Studies Faculty Publications and Presentations

In lieu of an abstract, here is a brief excerpt of the content:

Destruction of homelands. Loss of kinship species. Exposure to deadly contaminants. Mass extinction. Transformed lifeways. In the face of these radical changes, a question lingers: How long will life be possible? Recently the academy has also felt the urgency of these environmental problems and proposed to address them within the framework of the term "the Anthropocene." Indigenous studies has offered various responses to the Anthropocene, some arguing that it has utility in framing the violence of colonialism and others critiquing the limitations and assumptions behind the "anthropos" …

Defining Boundaries: How A City And County Addressed Legalized Recreational Marijuana, Tera Kathleen Hinkley-Bressi

Geography Masters Research Papers

In 2012 Washington state voters legalized recreational marijuana; local jurisdictions retained the option to ban recreational marijuana production, processing, and/or retail sales. Licenses for marijuana business could be distributed by the state to licensees in areas where local laws prohibited the business. This disconnect prompted legal battles between local governments and would-be business owners, as exemplified in the central Washington county of Yakima and the county seat, the city of Yakima. After a series of state policy changes and local community outcry, the city of Yakima reversed its initial ban, while the county continued prohibition. This paper explores issues underlying …

The Impact Of Attending An Equity-Based Conference On One Teacher Educator: Five Pedagogical Changes Of Practice, Rebecca Smith

Northwest Journal of Teacher Education

This article is a reflective overview of five pedagogical practice changes that one teacher educator made after attending a multicultural education conference. The article integrates current research to highlight the educational benefits of innovative, equity-based instructional strategies. The pedagogical changes are explored through the theoretical lens of culturally relevant pedagogy (Ladson-Billings, 1995; Gay, 2010) and culturally sustaining pedagogy (Paris & Alim, 2017) and include: diversifying curriculum, engaging with community partners, collaborating with K-12 practitioners, innovative technology, and self-reflection.

Perceptions Of Teacher-Writers: Initial Influences To Write, Shari L. Daniels, Pamela Beck

Northwest Journal of Teacher Education

This qualitative case study explores perceptions of teacher-writers’ early writing histories and examines their initial influences to write. Interviews and writing artifacts of ten K-12 teacher-writers serve as the primary data source. Findings indicate that teachers with strong identities as readers and/or writers in their K-12 experiences often received positive feedback which encouraged them to develop as writers, while teachers challenged with mechanics often received negative feedback which discouraged them from writing. Revisiting negative writing histories reshaped writing beliefs to influence a positive writing identities. The authors suggest practices for pre-service literacy courses to examine writing histories and to develop …

"We Were At Our Journey's End" : Settler Sovereignty Formation In Oregon, Katrine Barber

History Faculty Publications and Presentations

For too long, Oregon history has been captive to the mid-nineteenth-century’s rambling wagon trains. Settler stories of motivations, hardships, and achievements, preserved in diaries, letters, and memoirs, are compelling and deserving of the attention lavished on them. But more is necessary. Oregon’s Euro-Americans were intimately tied to national and international events that saw the rise of White, European colonial expansion into the colored word. Alongside that expansion was the development of a framework of domination, justified by claims of superiority and destiny, that conflated the ability to control with the right to do so. Placing Oregon history in this larger …

Classification Of Aerosol Population Type And Cloud Condensation Nuclei Properties In A Coastal California Littoral Environment Using An Unsupervised Cluster Model, Samuel A. Atwood, Sonia M. Kreidenweis, Paul J. Demott, Markus D. Petters, Gavin Cornwell, Andrew C. Martin, Kathryn A. Moore

Geography Faculty Publications and Presentations

Aerosol particle and cloud condensation nuclei (CCN) measurements from a littoral location on the northern coast of California at Bodega Bay Marine Laboratory (BML) are presented for approximately six weeks of observations during the boreal winter–spring as part of the CalWater-2015 field campaign. The nature and variability of surface (marine boundary layer, MBL) aerosol populations were evaluated by classifying observations into periods of similar aerosol and meteorological characteristics using an unsupervised cluster model to derive distinct littoral aerosol population types and link them to source regions. Such classifications support efforts to understand the impact of changing aerosol properties on precipitation …

From Nativism To White Power: Mid-Twentieth-Century White Supremacist Movements In Oregon, Shane Burley, Alexander Ross

Geography Faculty Publications and Presentations

Two document cases in the Oregon Historical Society (OHS) Research Library's George Rennar papers contain significant documentation of White supremacist organizations that developed in Oregon during the period between World War I and World War II. In this Research Files article, Shane Burley and Alexander Reid Ross highlight connections found within the collection between the variety of interlinked, racist, and nationalist organizations during that time period. Burley and Ross argue that while “membership numbers remained relatively small, these organizations provided a crucial link to the development of radical right-wing groups during the postwar era.”

Homelessness Count Methodologies Literature Review, Jennifer Lee-Anderson

Homelessness Research & Action Collaborative Publications and Presentations

This literature review on homeless count methods provides a brief history of homelessness in the U.S., an account of count efforts, and an overview of methods used. It illustrates that no method is capable of providing a comprehensive count of the homeless, and all methods have inherent disadvantages that often rely upon flawed assumptions. The practical impact of these counts on policy is substantial. Therefore, this review should encourage discussion as to what data communities need for policy and program development and implementation, and whether homeless counts actually fulfill this need.

Life Expectancy, Institute Of Portland Metropolitan Studies

Metroscape

Using Center for Disease Control data, we can visualize the spatial distribution of life expectancy estimates. For reference, the life expectancy of an average adult within the United States born in 2016 is 78.6 years. In the Portland Metropolitan region, 34 percent of the population lives in tracts with an average life expectancy below the United States average. These tracts are clustered largely in east Portland and Gresham. Future research should consider exploring other factors related to life expectancy such as race, income, and education.

Forms part of the continuing series Indicators of the Metroscape.
