Portland’S Response To The Western North American Heatwave: A Brief Report, Athanasios Burlotos, Caleb Dresser, Vivek Shandas Nov 2023

Portland’S Response To The Western North American Heatwave: A Brief Report, Athanasios Burlotos, Caleb Dresser, Vivek Shandas

Geography Faculty Publications and Presentations

Background:

In June of 2021, a heatwave resulted in high mortality across the Pacific Northwest region. The city of Portland, Oregon, had many advantages: emergency response personnel, science-based policies, political support for climate change adaptation, and collaboration among municipal, county, state, and federal authorities. Though the city’s response likely prevented many deaths, heat-related mortality was high.

Methods:

This study presents a retrospective case analysis of the 2021 Western North American Heatwave in Portland, Oregon. Specifically, the study examines the limitations of current heatwave response paradigms by means of a narrative review of the heatwave response and impacts.

Results:

Most deaths …

Subseasonal Clustering Of Atmospheric Rivers Over The Western United States, Emily Slinskey, Paul Loikith, Naomi Goldenson, Jesse Norris, Jesse Hall Nov 2023

Subseasonal Clustering Of Atmospheric Rivers Over The Western United States, Emily Slinskey, Paul Loikith, Naomi Goldenson, Jesse Norris, Jesse Hall

Geography Faculty Publications and Presentations

The serial occurrence of atmospheric rivers (ARs) along the US West Coast can lead to prolonged and exacerbated hydrologic impacts, threatening flood-control and water-supply infrastructure due to soil saturation and diminished recovery time between storms. Here a statistical approach for quantifying subseasonal temporal clustering among extreme events is applied to a 41-year (1979–2019) wintertime AR catalog across the western United States (US). Observed AR occurrence, compared against a randomly distributed AR timeseries with the same average event density, reveals temporal clustering at a greater-than-random rate across the western US with a distinct geographical pattern. Compared to the Pacific Northwest, significant …


When Communities Face Drinking Water Crises, Bottled Water Is A 'Temporary' Solution That Often Lasts Years--And Worsens Inequality, Daniel Jaffee Oct 2023

When Communities Face Drinking Water Crises, Bottled Water Is A 'Temporary' Solution That Often Lasts Years--And Worsens Inequality, Daniel Jaffee

Sociology Faculty Publications and Presentations

As a sociologist, I study the social and environmental effects of the rapid growth of bottled-water consumption in the U.S. and beyond, and how it is linked to distrust of public tap water. In my new book, “Unbottled,” one chapter examines how these dynamics played out in Flint. As its example shows, communities can end up relying on bottled water – often at great expense – for years after a crisis.


Critical Analysis Of Anti-Asian Hate In The News, Benardo Douglas Relampagos Oct 2023

Critical Analysis Of Anti-Asian Hate In The News, Benardo Douglas Relampagos

Dissertations and Theses

Since 2019, the United States has had an increase in violence against Asian American Pacific Islander (AAPI) communities along with an increase of mainstream anti-Asian racist rhetoric. Between 2021 and 2022, The Center for the Study of Hate & Extremism reported an overall 164% increase in anti-Asian hate crimes (Report to the Nation, 2021). While racism against black, Indigenous, people of color (BIPOC) communities has been the topic of an ever-growing body of critical discourse, prior to 2019 few publications had addressed racism and injustice regarding language choices and discourse in the context of anti-Asian rhetoric in the US, specifically …


The Impetus Of International Security In European Integration: The Nature Of Eu Common Security And Defense Policy, Osman Goktug Tanrikulu Oct 2023

The Impetus Of International Security In European Integration: The Nature Of Eu Common Security And Defense Policy, Osman Goktug Tanrikulu

Dissertations and Theses

This study explores the complicated relationship between security considerations and the European integration process. The research uncovers specific security factors that have shaped the EU integration process. Applying policy alignment and collective efforts for governance, this study offers a methodological improvement to the conventional status quo satisfaction concept within power transition theory.

Findings indicate that external militarized actions targeting European nations only occasionally disrupted integration in the short term. Instead, inner coordination among member states vis-à-vis external actors, promoted integration. During the early stages of integration, alignment with the EU collective was crucial, while aligning with regional leader Germany became …


The House Full Of Otters: Recalling Human–Sea Otter Relationships On An Indigenous Oregon Coast, Douglas Deur, Peter Hatch, Hannah Wellman Oct 2023

The House Full Of Otters: Recalling Human–Sea Otter Relationships On An Indigenous Oregon Coast, Douglas Deur, Peter Hatch, Hannah Wellman

Anthropology Faculty Publications and Presentations

Sea otters have held a special role in the cultural, spiritual, and economic life of Native American communities throughout recorded time. Along the coast of what is now Oregon, Native oral traditions recall a rich history of human encounters with sea otters, and speak of the species’ ubiquity, significance, and sentience. Native people also hunted sea otters, fashioning their uniquely dense fur into chiefly robes and using the pelts in ways central to community life — presaging the species’ later role in the global fur trade. Archaeological evidence of sea otter use can be found in sites of diverse antiquity …


Glimpses Of Oregon’S Sea Otters, Cameron La Follette, Douglas Deur Oct 2023

Glimpses Of Oregon’S Sea Otters, Cameron La Follette, Douglas Deur

Anthropology Faculty Publications and Presentations

Sea otters are an iconic species in the history of what is now known as Oregon. Their pelts brought great wealth in late eighteenth and nineteenth century China, motivating some of Oregon’s earliest exploration, trade, and contact between Native American and Euro-American people. Over time, hunting eliminated the species from Oregon’s coastal waters. This article provides a broad introduction to the history of Oregon’s now-extinct sea otter population, describing the emergence of the Chinese market that created and sustained the hunt, the British discovery of profits to be made by trading for the pelts, and the rise of American traders. …


The Invisible Slaughter: Local Sea Otter Hunters On The Oregon Coast, Cameron La Follette, Richard Ravalli, Peter Hatch, Douglas Deur, Ryan Tucker Jones Oct 2023

The Invisible Slaughter: Local Sea Otter Hunters On The Oregon Coast, Cameron La Follette, Richard Ravalli, Peter Hatch, Douglas Deur, Ryan Tucker Jones

Anthropology Faculty Publications and Presentations

Most accounts of the extirpation of sea otters from the Oregon coast focus on the well-documented international maritime fur trade of the late eighteenth and early nineteenth centuries. The historical record shows, however, that sea otters persisted much later. The final extirpation in Oregon occurred as a result of household-scale hunting by Native Americans and Euro-American settlers, from the mid-nineteenth century until around 1910. Especially on the south coast, a cottage industry of sea otter hunting flourished for decades — a pattern similar to the neighboring states of Washington and California. This article summarizes this long-ignored history, drawing from the …

In this article, the authors describe and illustrate an adapted expressive poetics research method through highlighting the experiences of Two Spirit, lesbian, gay, transgender, or queer (2SLGBTQ) Indigenous youth that participated in a culture-centered HIV prevention curriculum. It is our hope that through creating dialogic poems, we deepen and nuance the …


Transportation Academies As Catalysts For Civic Engagement In Transportation Decision-Making, Nathan W. Mcneil, Keith Bartholomew, Matthew Ryan Oct 2023

Transportation Academies As Catalysts For Civic Engagement In Transportation Decision-Making, Nathan W. Mcneil, Keith Bartholomew, Matthew Ryan

Urban Studies and Planning Faculty Publications and Presentations

Citizen planning academies, which became popular in the 1990s, are increasingly being used in transportation planning and decision-making contexts. By making use of a longer-term, multiweek educational format, transportation academies have the potential to reduce barriers and enhance community capital leading to more meaningful and sustained government community interaction. This paper tracks the rise of transportation academies in North America, and provides a detailed look at two academies: one in Portland, Oregon with a 30-year history, and another recently launched in the Salt Lake City, Utah region. Postacademy surveys of participants provided data that illuminated whether the transportation academy model …

Environmental Science and Management Faculty Publications and Presentations

Given the increasing demand for high-quality food and protein, global food security remains a challenge, particularly in the face of global change. However, since agriculture, food and water security are inextricably linked, they need to be examined via an interdisciplinary lens. Sociohydrology was introduced from a post-positivist perspective to explore and describe the bidirectional feedbacks and dynamics between human and water systems. This review situates sociohydrology in the agricultural domain, highlighting its contributions in explaining the unintended consequences of water management interventions, addressing climate change impacts due to/on agriculture and incorporating human behaviour into the description of agricultural water systems. …

Stress-Reduction From Positive Support: Impacts Of Receiving Partner Capitalization Support On Veteran Stress/Work Stress, Maryann Dona Samson Sep 2023

Stress-Reduction From Positive Support: Impacts Of Receiving Partner Capitalization Support On Veteran Stress/Work Stress, Maryann Dona Samson

Dissertations and Theses

Prolonged stress, a pervasive experience in the United States, has been linked to numerous adverse outcomes (Mayo Clinic, 2019). The workplace commonly operates as a source of chronic stressors (Colligan & Higgins, 2006), in fact 25% of Americans find their job is the most stressful part of life (NIOSH, 2021). This tendency is particularly true for military veterans, who reliably experience elevated stress and burnout (Smith et al., 2017) and low job satisfaction (Teclaw et al., 2016). Inspired by the pervasiveness and seriousness of the chronic stress issue, the current study addresses chronic stress in a veteran sample by examining …


Leed Buildings And Green Gentrification: Portland As A Case Study, Jordan Macintosh Sep 2023

Leed Buildings And Green Gentrification: Portland As A Case Study, Jordan Macintosh

Dissertations and Theses

LEED certification has become highly popular in the United State under the current political climate of addressing climate change, however in the implementation of green initiatives like LEED, social and economic impacts are not being considered. "Green gentrification" through the implementation of green initiatives such as LEED can cause displacement to highly vulnerable groups of people, disproportionately dealing the environmental goods to the wealthy and the environmental bads to the low income groups.

Portland has a fairly large amount of LEED buildings, and the city and state emphasizes its goals for sustainability through the use of green initiatives such as …


Left On "Read" And All Alone: Instigated Cyber Incivility, Shame, And Experienced Ostracism At Work, Alison Lucia Hunt Sep 2023

Left On "Read" And All Alone: Instigated Cyber Incivility, Shame, And Experienced Ostracism At Work, Alison Lucia Hunt

Dissertations and Theses

The mistreatment literature focused on workplace incivility has grown significantly over the past two decades, as it has been recognized as an omnipresent issue in the workplace. Workplace incivility presents itself as low-intensity rudeness in which at least one individual takes counter normative negative actions against another individual, and may take place in both office and remote work settings as well as through a cyber modality. These actions often occur in a spiral where the target of incivility becomes likely to perpetuate incivility later down the line. However, much of the incivility literature lacks a comprehensive understanding of the perpetrator's …


Mitigating Sex Trafficking: Preventative Methods For Reducing Sexual Exploitation, Autumn Rain Monroe Sep 2023

Mitigating Sex Trafficking: Preventative Methods For Reducing Sexual Exploitation, Autumn Rain Monroe

University Honors Theses

In recent years, sex trafficking has become more well-known in the public sphere, generating activism and legislation in an effort to combat this human rights issue. With this increased awareness comes challenges in appropriately understanding sex trafficking. The general public and even lawmakers often do not understand the complete dynamic or complexities of sex trafficking. Definitional inconsistencies make it difficult to provide a universal definition of sex trafficking, contributing to misconceptions involving the methods of entry and the barriers to exiting. Ultimately, this prevents proper identification of victims, hinders the protection of victims, and the implementation of survivor-oriented legislation, meaning …


Not On The Menu: Customer Sexual Harassment In The Restaurant Industry, Fernanda Wolburg Martinez Sep 2023

Not On The Menu: Customer Sexual Harassment In The Restaurant Industry, Fernanda Wolburg Martinez

Dissertations and Theses

Despite the high prevalence of customer sexual harassment (CSH) paired with a high turnover in the restaurant industry, there have been few suggestions on resources that may attenuate the effect that bystander and direct CSH might have on strain--anxiety and depressive symptoms--and turnover intentions among restaurant workers. Based on the stipulations of the job-demands resources theory and the empowerment framework, the current study frames direct and bystander CSH as job demands that may be linked to employee strain and turnover intentions. Moreover, CSH preventive supervisor behaviors and organizational intolerance towards CSH are introduced as job resources that may weaken the …

Similarities, Commonalities And Parallels In The Contributions Of Thorstein Veblen And Friedrich Nietzsche, John Battaile Hall Sep 2023

Similarities, Commonalities And Parallels In The Contributions Of Thorstein Veblen And Friedrich Nietzsche, John Battaile Hall

Economics Faculty Publications and Presentations

This inquiry seeks to establish that similarities, commonalities, and parallels can be identified in selected contributions advanced by Thorstein Veblen and Friedrich Nietzsche. In the main, their commonness is noted to appear in the critical approaches that also includes expressing deep-seated skepticism regarding the course to modernity, singling out institutions ruling society, and especially the economy—in the case of Veblen. Specialized in Philology, as Nietzsche extolls his Dionysian orientation this inquiry introduces the idea that Veblen’s foundation for his distinctly critical approach to ruling institutions also reflects a Dionysian perspective. In Thus Spoke Zarathustra (1883-85) Nietzsche introduces a character whom …


Structure-From-Motion Derived Snow Cover In Burned Forests Of The Western Oregon Cascades, Siobhan Ciafone Sep 2023

Structure-From-Motion Derived Snow Cover In Burned Forests Of The Western Oregon Cascades, Siobhan Ciafone

Dissertations and Theses

Forest fire occurrence in the western US has increased rapidly since the 1980s, and most western US fires occur in the seasonal snow zone. Burned forests influence snow accumulation and melt patterns for years following fire, and understanding drivers of variability in snow cover across a burned landscape at the basin-scale is necessary for accurate hazard prediction and water resource forecasting. Basin-scale surveys of snowpack are possible with remote sensing, but accurate sensing methods such as Light Detection and Ranging (LiDAR) are often cost-prohibitive. In the last decade, structure-from-motion (SfM), an optical remote sensing technique, has emerged as an affordable …

Adults’ Reading Engagement And Wellbeing In Aotearoa New Zealand, Stephen Reder Sep 2023

Adults’ Reading Engagement And Wellbeing In Aotearoa New Zealand, Stephen Reder

Applied Linguistics Faculty Publications and Presentations

Education and literacy have long been associated with a range of economic and social outcomes in industrialized societies. Recent research based on large-scale national and international surveys has examined effects of education and literacy on individuals’ social and economic outcomes. This paper takes a further step in understanding the importance of literacy for individuals’ economic and social outcomes by disentangling the effects of two different aspects of literacy, literacy proficiency as measured by standardized tests and reading engagement as measured by self-reports of everyday reading activities. Using recent nationally representative survey data from New Zealand, multivariate regression models estimate the …

This study aimed to: i. systematically review population-based studies of prevalence of ICD/DSM depressive disorder in Latin America, ii. report pooled regional, country, and sex-specific prevalence estimates, and iii. test its association with four country-level development indicators: human development (HDI), income (Gini) and gender inequality (GII), and intentional homicide rate (IHR).

Methods: We conducted a systematic review and meta-analysis of population-based studies reporting primary data on the prevalence of ICD/DSM depressive disorder in …


Lightning-Ignited Wildfires In The Western United States: Ignition Precipitation And Associated Environmental Conditions, Dmitri Alexander Kalashnikov, John T. Abatzoglou, Paul Loikith, Nicholas J. Nauslar, Yianna Sotirios Bekris, Deepti Singh Sep 2023

Lightning-Ignited Wildfires In The Western United States: Ignition Precipitation And Associated Environmental Conditions, Dmitri Alexander Kalashnikov, John T. Abatzoglou, Paul Loikith, Nicholas J. Nauslar, Yianna Sotirios Bekris, Deepti Singh

Geography Faculty Publications and Presentations

Cloud-to-ground lightning with minimal rainfall (“dry” lightning) is a major wildfire ignition source in the western United States (WUS). Although dry lightning is commonly defined as occurring with <2.5 mm of daily-accumulated precipitation, a rigorous quantification of precipitation amounts concurrent with lightning-ignited wildfires (LIWs) is lacking. We combine wildfire, lightning and precipitation data sets to quantify these ignition precipitation amounts across ecoprovinces of the WUS. The median precipitation for all LIWs is 2.8 mm but varies with vegetation and fire characteristics. “Holdover” fires not detected until 2–5 days following ignition occur with significantly higher precipitation (5.1 mm) compared to fires detected promptly after ignition (2.5 mm), and with cooler and wetter environmental conditions. Further, there is substantial variation in precipitation associated with promptly-detected (1.7–4.6 mm) and holdover (3.0–7.7 mm) fires across ecoprovinces. Consequently, the widely-used 2.5 mm threshold does not fully capture lightning ignition risk and incorporating ecoprovince-specific precipitation amounts would better inform WUS wildfire prediction and management.
