Institute on Aging Publications

Background: Brain health diplomacy aims to influence the global policy environment for brain health (i.e. dementia, depression, and other mind/brain disorders) and bridges the disciplines of global brain health, international affairs, management, law, and economics. Determinants of brain health include educational attainment, diet, access to health care, physical activity, social support, and environmental exposures, as well as chronic brain disorders and treatment. Global challenges associated with these determinants include large-scale conflicts and consequent mass migration, chemical contaminants, air quality, socioeconomic status, climate change, and global population aging. Given the rapidly advancing technological innovations impacting brain health, it is paramount to …

Centering Equity In Oregon’S 100 Year Water Vision: A Student-Led Policy Paper Prepared By The Oregon Water Stories Team At Portland State University, Clare T. Mcclellan, Sadie Boyers, Victoria Cali De Leon, Tony Cole, Laura Cowley-Martinson, Shersten Finley, Dustin Lanker, Julia Seydel, Aakash Nath Upraity, Janet Cowal, Melissa Haeffner

Environmental Science and Management Faculty Publications and Presentations

The purpose of this report is to provide evidence for the need to further intentionally incorporate equity into Oregon’s 100 Year Water Vision. Four case studies contextualize this need and highlight the variety of water issues throughout the state, supported by linguistic analyses of local newspapers. As Oregon policy-makers are responsible for ensuring working water systems for all Oregonians, we also suggest implementable criteria for the evaluation of equity in water issues and decision-making. This student-led and interdisciplinary report comes from the Haeffner-Cowal Oregon Water Stories research lab at Portland State University.

These topics include issues related to safety, social equity, active transportation, …

Rebranding Empire: Consumers, Commodities, And The Empire Marketing Board, 1926-1933, Ashley Kristen Bower

Dissertations and Theses

The Empire Marketing Board (EMB) was a British government organization established in 1926 by the Conservative Party, under the authority of Colonial Secretary Leopold Amery. Its goal was to encourage Britons to "Buy Empire," namely, to buy products from the Dominions and colonies of the British Empire. To encourage consumption, the EMB funded scientific research and economic analyses, as well as publicity for Empire trade in the form of posters, films, educational materials, and government-sponsored events. The Empire Marketing Board attempted to sell the concept of "Empire" to the masses as a new cooperative project which stressed the value of …

Crania Japonica: Ethnographic Portraiture, Scientific Discourse, And The Fashioning Of Ainu/Japanese Colonial Identities, Jeffrey Braytenbah

Dissertations and Theses

Japan's colonial activities on the island of Hokkaido were instrumental to the creation of modern Japanese national identity. Within this construction, the indigenous Ainu people came to be seen in dialectical opposition to the 'modern' and 'civilized' identity that Japanese colonial actors fashioned for themselves. This process was articulated through travel literature, ethnographic portraiture, and discourse in scientific racism which racialized perceived divisions between the Ainu and Japanese and contributed to the unmaking of the Ainu homeland: Ainu Mosir. The resulting narrative was used to legitimize Japanese imperialism, transforming the Empire of Japan into the only non-Western member state …

Glacial Meltwater Modeling To Simulate Lake Water Budget (1996-2013) In Taylor Valley, Antarctica, Julian Michael Cross

Dissertations and Theses

The McMurdo Dry Valleys (MDV), the largest ice-free region (4,500 km²) in Antarctica, are a polar desert with an average annual temperature of -18ºC. In Taylor Valley, one of the MDV, closed-basin, perennially ice-covered lakes occupy the valley floor. Their water balance is controlled by inflow from glacial meltwater runoff and loss due to sublimation, making them sensitive indicators of climate. In this study, a physically-based model of glacier meltwater and lake ice sublimation is adapted to explain modern (1996 to 2013) lake-level variations. Meltwater model results were improved by the inclusion of MODIS remotely-sensed albedo measurements (E …

Computer Science For Equity: Teacher Education, Agency, And Statewide Reform, Joanna Goode, Max Skorodinsky, Jill Hubbard, James Hook

Computer Science Faculty Publications and Presentations

This paper reports on a statewide “Computer Science for All” initiative in Oregon that aims to democratize high school computer science and broaden participation in an academic subject that is one of the most segregated disciplines nationwide, in terms of both race and gender. With no statewide policies to support computing instruction, Oregon's legacy of computer science education has been marked by both low participation and by rates of underrepresented students falling well-below the already dismal national rates. The study outlined in this paper focuses on how teacher education can support educators in developing knowledge and agency, and impacting policies …

Space And Colonial Alterity: Interrogating British Residential Segregation In Nigeria, 1899-1919, Bright Alozie

Black Studies Faculty Publications and Presentations

The policy of segregation is undoubtedly a resented feature of colonial rule in Africa. However, discussions of the residential racial segregation policy of the British colonial administration in Africa invariably focus on “settler colonies” of South, Central, and East Africa. British colonial West Africa hardly features in such discussions since it is widely believed that these areas, which had no large-scale European settler populations, had no experience relevant to any meaningful discussion of multi-racial colonial relationships. Some studies even deny the existence of racially segregated areas in places other than the settler colonies. Despite evidence that residential racial segregation formed …

A Case Study Of Drone Delivery Reliability For Time-Sensitive Medical Supplies With Stochastic Demand And Meteorological Conditions, Travis B. Glick, Miguel Figliozzi, Avinash Unnikrishnan

Civil and Environmental Engineering Faculty Publications and Presentations

Drones are increasingly being utilized to deliver medical supplies, and the COVID-19 pandemic has accelerated this trend. Drones arrive quickly by taking more direct paths and avoiding ground-based obstructions. However, drones are not completely reliable and may also experience failures and delays. For consumer products, delivery delays are an inconvenience, but for some medical supplies, delays may be fatal. This research focuses on the drone reliability of one particular type of supply and event: automatic defibrillators for out-of-hospital cardiac arrests (OHCA). A modeling framework is developed to analyze drone delivery reliability with stochastic demands and meteorological conditions. Using probability distributions …

Predicted Responses Of Beaches, Bays, And Inner-Shelf Sand Supplies To Potential Sea Level Rise (0.5-1.0 M) In Three Small Littoral Subcells In The High-Wave-Energy Northern Oregon Coast, Usa, Curt D. Peterson, Debra Lee Doyle, Charles L. Rosenfeld, Kara E. P. Kingen

Geology Faculty Publications and Presentations

Three small subcells (Nehalem, Tillamook, and Netarts) totaling ~55 km shoreline length in the high-wave energy northern Oregon coast are evaluated for potential beach sand loss from sea level rise (SLR) of 0.5–1.0 m during the next century. The predicted erosion is based on beach sand displacement from the narrow beaches (average ~120 m width) to increased submarine accommodation spaces in the innermost-shelf (to 30 m water depth) and in the subcell estuaries (Tillamook Bay, Netarts Bay, and Nehalem Bay), following predicted near-future SLR. Beach sand sources from local rivers, paleo-shelf deposits, and/or sea cliff retreat are discriminated by distinctive …

A New Innovation Paradigm: European Cohesion Policy And The Retreat Of Public Science In Countries In Europe's Scientific Periphery, Jadranka Švarc, Marina Dabic, Tugrul Daim

Engineering and Technology Management Faculty Publications and Presentations

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the …

Examining The Complex Relationship Between Innovation And Regulation Through A Survey Of Wastewater Utility Managers, Luke Sherman, Alida Cantor, Anita Milman, Michael Kiparsky

Geography Faculty Publications and Presentations

Despite pressures to increase performance and decrease costs, innovation has been slow to emerge in the municipal wastewater sector. The relationship between regulation and innovation in this sector is a particularly interesting aspect of this conundrum, given the degree to which public utility decision-making is influenced by regulation. Using a national survey, this paper examines US wastewater utility managers’ perceptions of how regulation influences the adoption of new technologies. Recognizing that the relationship between innovation and regulation is complex, we develop the concept of regulation as multifaceted and examine three interrelated aspects of regulation: (1) regulatory requirements, (2) regulators and …

Associations Of Neighborhood Socioeconomic Conditions With Self-Rated Health, Mental Distress, And Health Behaviors: A Nationwide Cross-Sectional Study In Japan, Tomoya Hanibuchi, Tomoki Nakaya

Geography Faculty Publications and Presentations

Although associations between neighborhood socioeconomic conditions and health have been well established, their geographical scope is mostly limited to Western societies, while multilevel studies in the non-Western context (e.g., Japan) are limited to specific cities/regions within countries. This consequently limits the external validity of the findings. To fill the gap, this study examined the associations between neighborhood socioeconomic conditions and health-related indicators by using nationwide cross-sectional data in Japan. Individual data was collected from a nationwide online survey conducted in 2015 (n = 4593). Self-rated health, mental distress (Kessler Psychological Distress Scale: K6), smoking, and physical activity were analyzed in …

A Digital Archive Of Human Activity In The Mcmurdo Dry Valleys, Antarctica, Adrian Howkins, Stephen M. Chignell, Poppie Gullett, Andrew G. Fountain, Melissa Carrie Brett, Evelin Preciado

Geography Faculty Publications and Presentations

Over the last half century, the McMurdo Dry Valleys (MDV) of East Antarctica have become a globally important site for scientific research and environmental monitoring. Historical data can make important contributions to current research activities and environmental management in Antarctica but tend to be widely scattered and difficult to access. We address this need in the MDV by compiling over 5000 historical photographs, sketches, maps, oral interviews, publications, and other archival resources into an online digital archive. The data have been digitized and georeferenced using a standardized metadata structure, which enables intuitive searches and data discovery via an online interface. …

Evaluating Cmip6 Model Fidelity At Simulating Non-Gaussian Temperature Distribution Tails, Arielle J. Catalano, Paul Loikith, J. David Neelin

Geography Faculty Publications and Presentations

Under global warming, changes in extreme temperatures will manifest in more complex ways in locations where temperature distribution tails deviate from Gaussian. Confidence in global climate model (GCM) projections of temperature extremes and associated impacts therefore relies on the realism of simulated temperature distribution tail behavior under current climate conditions. This study evaluates the ability of the latest state-of-the-art ensemble of GCMs from the Coupled Model Intercomparison Project phase six (CMIP6), to capture historical global surface temperature distribution tail shape in hemispheric winter and summer seasons. Comparisons with a global reanalysis product reveal strong agreement on coherent spatial patterns of …

Socio-Hydrology: An Interplay Of Design And Self-Organization In A Multilevel World, David J. Yu, Heejun Chang, Taylor T. Davis, Vicken Hillis, Landon T. Marston, Woi Sok Oh, Murugesu Sivapalan, Timothy M. Waring

Geography Faculty Publications and Presentations

The emerging field of socio-hydrology is a special case of social-ecological systems research that focuses on coupled human-water systems, exploring how the hydrologic cycle and human cultural traits coevolve and how such coevolutions lead to phenomena of relevance to water security and sustainability. As such, most problems tackled by socio-hydrology involve some aspects of engineering design, such as large-scale water infrastructure, and self-organization in a broad context, such as cultural change at the population level and the hydrologic shift at the river basin or aquifer level. However, within the field of socio-hydrology, it has been difficult to find general theories …

Central Tokyo’S Low Response Rate To The 2015 Population Census And Its Related Factors, Tomoya Hanibuchi, Masakazu Yamauchi

Geography Faculty Publications and Presentations

Recently, there has been an increase in the number of “unreported” cases in the Population Census of Japan caused by nonresponses to the survey. Subsequently, this has led to data reliability challenges. In light of this problem, the factors related to the low response rate of the 2015 Population Census in the central Tokyo area are examined in the present study. An online survey was conducted among individuals residing in the three Special Wards of Tokyo to inquire about their responses (submitted or not submitted) to the previous census. The statistical analyses demonstrated that particularly in central Tokyo, middle-aged (35–49 …

Crossing Boundaries: Steps Toward Measuring Undergraduates' Interdisciplinary Science Understanding, Brie Tripp, Sophia A. Voronoff, Erin Shortlidge

Biology Faculty Publications and Presentations

A desired outcome of education reform efforts is for undergraduates to effectively integrate knowledge across disciplines in order to evaluate and address real-world issues. Yet there are few assessments designed to measure if and how students think interdisciplinarily. Here, a sample of science faculty were surveyed to understand how they currently assess students’ interdisciplinary science understanding. Results indicate that individual writing-intensive activities are the most frequently used assessment type (69%). To understand how writing assignments can accurately assess students’ ability to think interdisciplinarily, we used a preexisting rubric, designed to measure social science students’ interdisciplinary understanding, to assess writing assignments …

Walking Dena’Ina: A Cultural Landscape Report For The Telaquana Trail, Douglas Deur, Jamie Hebert, John Branson, Tricia Brown

Anthropology Faculty Publications and Presentations

The Telaquana Trail is an ancient pathway ascending from the shores of Qizhjeh Vena, Lake Clark, through tundra and timbered valleys, into a high-elevation expanse of rolling tundra and smaller interior lakes nearly 50 miles north of Lake Clark. The pathway is an ancestral corridor used by Native peoples since the beginning of remembered time. Though the archaeological record of the trail is still coming into focus, it lends us important clues about the trail and how it was used. For example, archaeological evidence at places like Twin Lakes and Snipe Lake suggests that ancestral Native communities occupied and traveled …

This research focuses on the efficiency of autonomous (driverless) delivery vehicles in terms of vehicle-miles, energy consumption, and carbon emissions. Drones or UAVs, sidewalk autonomous delivery robots (SADRs), and road autonomous delivery robots (RADRs) vehicles carbon emissions are compared against emissions from an electric van (e-van), a conventional internal combustion engine van, and driving to a store utilizing electric and conventional vehicles. The impacts of vehicle capacity, range, and time constraints are analyzed as well as …

First Report Of Molecular Characterization And Phylogeny Of Trichuris Fossor Hall, 1916 (Nematoda: Trichuridae), Malorri R. Hughes, Deborah A. Duffield, Dana K. Howe, Dee Denver

Biology Faculty Publications and Presentations

Because species of Trichuris are morphologically similar and ranges of host preference are variable, using molecular data to evaluate species delineations is essential for properly quantifying biodiversity of and relationships within Trichuridae. Trichuris fossor has been reported from Thomomys spp. (Rodentia: Geomyidae, ‘pocket gophers’) hosts based on morphological features alone. Partial 18S rRNA sequences for specimens identified as T. fossor based on morphology, along with sequences from 26 additional taxa, were used for a phylogenetic analysis. Evolutionary histories were constructed using maximum likelihood and Bayesian inference. In both analyses, the specimens fell within the Trichuris clade with 100% support and …

Disturbance Refugia Within Mosaics Of Forest Fire, Drought, And Insect Outbreaks, Meg A. Krawchuk, Garrett W. Meigs, Jennifer M. Cartwright, Jonathan D. Coop, Raymond Davis, Andres Holz, Crystal Kolden, Arjan Jh Meddens

Geography Faculty Publications and Presentations

Disturbance refugia – locations that experience less severe or frequent disturbances than the surrounding landscape – provide a framework to highlight not only where and why these biological legacies persist as adjacent areas change but also the value of those legacies in sustaining biodiversity. Recent studies of disturbance refugia in forest ecosystems have focused primarily on fire, with a growing recognition of important applications to land management. Given the wide range of disturbance processes in forests, developing a broader understanding of disturbance refugia is important for scientists and land managers, particularly in the context of anthropogenic climate change. We illustrate …

Dropsonde Observations Of The Ageostrophy Within The Pre-Cold-Frontal Low-Level Jet Associated With Atmospheric Rivers, Rueben Demirdgian, Joel R. Norris, Andrew Martin, F. Martin Ralph

Geography Faculty Publications and Presentations

The pre-cold-frontal low-level jet (LLJ) is an important contributor for water vapor transport within atmospheric rivers, though its dynamics are not completely understood. The present study investigates the LLJ using dropsonde observations from 24 cross-atmospheric river transects taken during the CalWater-2014, 2015 and the AR-Recon 2016, 2018 field campaigns. It is found that the LLJ, located at ;1-km elevation ahead of the cold front, has an average maximum wind speed of 30ms21 and is strongly supergeostrophic with an average ageostrophic component of 6ms21. The alongfront ageostrophy occurs within the atmospheric layer (750–1250 m) known to strongly control orographic precipitation associated …

Counting Everyone Because Everyone Counts: The Value Of Census Data For Local Decision Making, Uma Krishnan

Metroscape

Once every ten years the US Census Bureau conducts the decennial United States census, and 2020 is the year. The census is a national effort to count everyone in the United States. Unfortunately, this year the COVID-19 pandemic has captured the nation’s attention even as the 2020 census struggles to claim relevance and broaden its reach. At the same time, census data has emerged as a critical tool for examining stark inequities in the demographics of who is contracting and dying of COVID-19. This year, counting everyone is more important than ever.

Potential Greenhouse Gas Reductions From Natural Climate Solutions In Oregon, Usa, Rose A. Graves, Ryan D. Haugo, Andres Holz, Max Nielsen-Pincus, Aaron Jones, Bryce Kellogg, Cathy Macdonald, Kenneth Popper, Micheal Schindel

Environmental Science and Management Faculty Publications and Presentations

Increasing concentrations of greenhouse gases (GHGs) are causing global climate change and decreasing the stability of the climate system. Long-term solutions to climate change will require reduction in GHG emissions as well as the removal of large quantities of GHGs from the atmosphere. Natural climate solutions (NCS), i.e., changes in land management, ecosystem restoration, and avoided conversion of habitats, have substantial potential to meet global and national greenhouse gas (GHG) reduction targets and contribute to the global drawdown of GHGs. However, the relative role of NCS to contribute to GHG reduction at subnational scales is not well known. We examined …

Environmental Science and Management Faculty Publications and Presentations

Microplastics (MPs) are anthropogenic contaminants found in coastal and marine environments worldwide. Pacific razor clams (Siliqua patula), important for local indigenous culture, economy, gastronomy and food security along the United States West Coast, are subjected to myriad environmental stressors including predation, storm events, disease, toxins, and MPs. This study aimed to determine MP burdens in Olympic Coast, Washington Pacific razor clams and estimate annual MP exposure of recreational razor clam harvester-consumers from eating this species. We quantified suspected MP burdens in Pacific razor clams collected from eight tribal, recreational, and commercial harvest areas on the Olympic Coast in April 2018. …

The Impact Of Paying For Forest Conservation On Perceived Tenure Security In Ecuador, Kelly W. Jones, Nicolle Etchart, Margaret Holland, Lisa Naughton-Treves, Rodrigo A. Arriagada

Forest Collaborative Research

We study the impact of Ecuador’s national forest conservation incentives program on reported land conflicts. Data come from a survey of > 900 households located within 49 indigenous and Afro-Ecuadorian communities holding communal conservation contracts.We use quasi-experimental methods to test for relationships between program participation and changes in land conflicts. Respondents reported that the program reduced land conflicts when households resided in communities with de facto communal tenure arrangements (vs. de facto semiprivate arrangements).We find no evidence that the conservation incentive program increased land conflicts. These results counter concerns that conservation payments undermine land tenure security; in some cases perceived tenure …
