Open Crime Maps: How Are Police Departments Doing So Far?, Khaing Sandee Lynn

Dissertations and Theses

In recent years, some police departments have started providing open crime maps depicting select crime-related data. However, there has been no studies so far evaluating map delivery sources, the type of maps delivered, and why agencies might be doing so. Using a random, stratified sample of 1,677 police departments from the 2013 Law Enforcement Management and Administrative Statistics (LEMAS) survey, the current study examines how many police departments provide access to online crime maps as well as how they are delivered (externally or internally) and prevalent map types (dot, density, choropleth, etc.). Furthermore, whether or not agencies provided a justification(s) …

Webinar: Electric Bus Deployment: Cost And Environmental Equity, Cathy Liu

TREC Webinar Series

This presentation introduces an innovative spatiotemporal analytical framework and web-based visualization platform developed by researchers at the University of Utah to assist transit agencies in identifying optimal deployment strategies for a battery-electric bus (BEB) system by using a combination of mathematical programming methods, GIS-based analysis, and multi-objective optimization techniques. The framework allows transit agencies to optimally phase in BEB infrastructure and deploy the BEB system in a way that can minimize the capital and operational cost of the BEB system while maximizing its environmental benefits (i.e., emission reduction).

A Community Of Fear: Emotion And The Hydro-Social Cycle In East Porterville, Michael Egge

Geography Masters Research Papers

Broader governance challenges driving water insecurity globally are well documented in the literature, however the power-laden relationships and emotions that shape water access at the household and community levels are yet to be fully investigated, especially in the context of water consolidation projects. In this article, we examine the role of emotions in mediating access to water and in the production of resource struggles among marginalized communities existing outside of conventional regulatory frameworks. We bring together two relational approaches – the hydro-social cycle and emotional political ecology – to examine water insecurity and how it manifests in the historically disadvantaged …

Understanding Financial And Human Resource Capacity Challenges Among Small Nonprofits In Oregon: How To Overcome Challenges Unique To Size And Urban-Rural Divide, Anindita Mukerjee

Dissertations and Theses

Nonprofit and voluntary organizations are part of the political economy that add to the services of public and private sectors by addressing civic interests, participation in democracy and providing social programs that improve quality of life. This sector is mostly comprised of small organizations whose impact is more than their budget size. At the advent of this study, information existed about the needs and capacity challenges of Oregon nonprofits in general but lacked specifics on smaller organizations, especially differentiating the urban rural distinction. The aim of this research was to explore the financial and human resource capacity of small nonprofit …

State Of Aging In Portland, Alan Kenneth Delatorre, Richard Lycan, Margaret Neal

Institute on Aging Publications

Introduction

From 2006-2019, the Age-Friendly Portland Initiative operated as a city-university- community partnership that began in 2006, resulting from a global World Health Organization (WHO) research project. In 2010, the City of Portland joined the WHO Global Network of Age-Friendly Cities and Communities and in 2012, it also joined the AARP Network of Age-Friendly States and Communities. The Action Plan for an Age- friendly Portland was passed by Resolution by Portland City Council in 2013 (Resolution No. 37039) and contains 10 domains: (1) housing; (2) transportation; (3) outdoor spaces and buildings; (4) employment and the economy; (5) civic participation and …

Parking Spaces To People Places, Shawn Canny, Natalie Knowles, Arva Hussain, Ann Le, Megan Doherty, Elizabeth Cox

Master of Urban and Regional Planning Workshop Projects

In partnership with the Portland Bureau of Planning and Sustainability (BPS), we sought to better understand how off-street parking space could accommodate economic activity in East Portland, the city’s most economically and racially diverse neighborhood. We focused on two different neighborhoods based on equity considerations and interest: the Rosewood and the Jade Districts. The goal was to better understand these areas with granularity but also to juxtapose them looking for similarities and differences that could guide our recommendations for using parking spaces and serving the community. This project was exploratory in nature. Our research questions and resulting deliverables were dynamic. …

Broad-Scale Surface And Atmospheric Conditions During Large Fires In South-Central Chile, David B. Mcwethy, René D. Garreaud, Andres Holz, Gregory T. Pederson

Geography Faculty Publications and Presentations

The unprecedented size of the 2017 wildfires that burned nearly 600,000 hectares of central Chile highlight a need to better understand the climatic conditions under which large fires develop. Here we evaluate synoptic atmospheric conditions at the surface and free troposphere associated with anomalously high (active) versus low (inactive) months of area burned in south-central Chile (ca. 32–41° S) from the Chilean Forest Service (CONAF) record of area burned from 1984–2018. Active fire months are correlated with warm surface temperatures, dry conditions, and the presence of a circumpolar assemblage of high-pressure systems located ca. 40°–60° S. Additionally, warm surface temperatures …

Detecting Change In Precipitation Indices Using Observed (1977-2016) And Modeled Future Climate Data In Portland, Oregon, Usa, Alexis Kirsten Cooley, Heejun Chang

Geography Faculty Publications and Presentations

This study addresses how regional changes to precipitation may be identified by exploring the effect of temporal resolution on trend detection. Climate indices that summarize precipitation characteristics are used with Mann–Kendall monotonic testing to investigate precipitation trends in Portland, Oregon (OR) from 1977 to 2016. Observational records from rain gages are compared with downscaled global climate models to determine trends for the historic (1977–2005) and future (2006–2100) periods. Standard indices created by the Expert Team on Climate Change Detection and Indices (ETCCDI) are deployed. ETCCDI indices that summarize conditions at the annual level are generated alongside a limited number of …

Agency, Sense Of Place, And Knowledge On The Zumwalt Prairie: A Social Study Of Place-Based Conservation And Resilience, Dana Elyse Hellman

Dissertations and Theses

Shifting and often diminishing environmental conditions, due to climate change, resource loss, and ecosystem degradation, pose a significant concern to both social and ecological systems. The field of conservation science has attempted to address environmental threats through varying approaches, transitioning from fortress conservation and complete human exclusion to community-based and co-managed models which incorporate human actors and social dimensions in the conservation process. The latest iteration of conservation scholarship, place-based conservation, is deeply rooted in interdisciplinary, social scientific thinking, and calls for significant practitioner engagement with local knowledge, practices, social constructions, and place meanings. It is an approach which emphasizes …

Session 2: Panel 2: Presenter 1 (Paper) -- A Brief History Of Footwear, Tobias B. Boudreau

Young Historians Conference

The use of footwear as a unit of analysis will help historians re-evaluate the relationship between technological diffusion and culture. Shoes are a common item across the globe, regardless of geographical, cultural, and economic divisions, and have been for a long time. Footwear reflects the sociopolitical, economic, and cultural environment of its owner, as well as characteristics of the owner themself. Shoes have taken on significant symbolic roles in art, literature, and everyday life. Essay is divided into four sections; Prehistory, Ancient, Middle Ages, Modern. Various examples from each time period are explained, compared with one another, and connected together …

Session 1: Panel 1: Presenter 2 (Paper) -- The Rogue River War 1855-1856, Sara E. Shallenberger

Young Historians Conference

The Rogue River War of 1855 to 1856 was a series of armed conflicts fought between U.S. Army regulars, local militia, and a conglomerate of indigenous groups in the Rogue River watershed. The main cause of the conflict was the intrusion of white settlers and miners into the territory of the indigenous people of the Rogue River. These white immigrants misused resources upon which the local indigenous people relied and violently retaliated against local indigenous people for misdeeds they often did not commit. The Lupton Massacre, Battle of Hungry Hill, and the Battle of Big Bend serve as critical points …

Session 1: Panel 1: Presenter 3 (Paper) -- The Alaska Native Claim Settlement Act: The Impact On Alaskan Natives, Madeleine G. Stewart

Young Historians Conference

Alaska Natives have been living on the land that is now known as Alaska since time immemorial. Although that is the case, legally that does not give them immediate rights to the land in the colonial world. The Alaska Native Claims Settlement Act of 1971 (ANSCA) was put in place to resolve the aboriginal land claims that were ignored when Alaska became a state in 1959. This forced Alaskan Natives to come together and make an agreement with the United States government. In the end, ANCSA made it possible to exploit the land for natural resources, which greatly impacted and …

Economic Primer & Policy Analysis: Rent Control Policies & Oregon Sb-608, Gabrielle A. Brown

Hatfield Graduate Journal of Public Affairs

Rent control policies are controversial. They create significant winners and losers and raise serious questions about the prioritization of certain segments of society with others and economic concerns with moral ones. With such dynamics, it is a given that there are no easy answers, at least not to those not given to ideological posturing. The fact is that housing is both an economic system and a human one, with very real ramifications for those involved, which just happens to be everyone.

In 2019, the State of Oregon passed SB-608, a bill intended to address two primary concerns: rental cost growth …

Introduction: Managed Retreat And Environmental Justice In A Changing Climate, A. R. Siders, Idowu Ajibade

Geography Faculty Publications and Presentations

In response to global climate change, managed retreat has emerged as a controversial adaptation strategy. The purposeful movement of people and communities away from hazardous places raises numerous social and environmental justice concerns that will become even more pressing as retreat occurs more frequently and at larger scales. This special issue contributes to an emerging body of literature on managed retreat by providing a range of perspectives and approaches to considering justice in managed retreat. The assembled papers represent diverse voices(including perspectives from individuals whose communities are currently relocating or considering relocation), disciplines (including oral histories, legal analyses, and cultural …

Chemical Characterization Of Toxicologically Relevant Molecules In Cannabis Concentrates And Vaporizer Aerosols, Jiries Meehan-Atrash

Dissertations and Theses

Consumption of cannabis concentrates using the relatively novel non-combustion methods dabbing and vaping has steadily grown in popularity as cannabis legalization in North America has allowed increased access to sophisticated cannabis products and technology. In order to assess the safety of these products, it is necessary to gain a chemical understanding of the decomposition reactions that occur when the active ingredients are heated in the conditions seen when dabbing or vaping. This dissertation contains a manuscript that details efforts to structurally characterize a toxic cannabis concentrate adulterant, and three manuscripts that studied the chemical decomposition of the two primary cannabis …

Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub

TREC Webinar Series

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the …

Joint Effects Of Ethnic Enclave Residence And Ambient Volatile Organic Compounds Exposure On Risk Of Gestational Diabetes Mellitus Among Asian/Pacific Islander Women In The United States, Andrew D. Williams, Sandie Ha, Edmond Shenassa, Lynne C. Messer, Jenna Kanner, Pauline Mendola

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Asian/Pacific Islander (API) communities in the United States often reside in metropolitan areas with distinct social and environmental attributes. Residence in an ethnic enclave, a socially distinct area, is associated with lower gestational diabetes mellitus (GDM) risk, yet exposure to high levels of air pollution, including volatile organic compounds (VOCS), is associated with increased GDM risk. We examined the joint effects of ethnic enclaves and VOCs to better understand GDM risk among API women, the group with the highest prevalence of GDM.

Methods:

We examined 9069 API births in the Consortium on Safe Labor (19 hospitals, 2002–2008). API ethnic …

Assessment Of Urban Flood Vulnerability Using The Social-Ecological-Technological Systems Framework In Six Us Cities, Heejun Chang, Arun Pallathadka, Jason Sauer, Nancy B. Grimm, Rae Zimmerman, Chingwen Cheng, David Iwaniec, Yeowon Kim, Multiple Additional Authors

Geography Faculty Publications and Presentations

As urban populations continue to grow through the 21st century, more people are projected to be at risk of exposure to climate change-induced extreme events. To investigate the complexity of urban floods, this study applied an interlinked social-ecological-technological systems (SETS) vulnerability framework by developing an urban flood vulnerability index for six US cities. Indicators were selected to reflect and illustrate exposure, sensitivity, and adaptive capacity to flooding for each of the three domains of SETS. We quantified 18 indicators and normalized them by the cities’ 500-yr floodplain area at the census block group level. Clusters of flood vulnerable areas were …

Feedback Timing: Relationship To Student Success In Online Education, Emaleia J. Anton, Nicholas A. Smith

It’s important that researchers identify factors that support student success in online education because utilization of remote learning has increased over the years. Feedback timing is a vital factor contributing to student success in online educational environments. The purpose of this research is to experimentally examine effects of feedback timing on online student success, which this study operationalizes as student perception of self-efficacy. Conducting a between-subjects experimental design, 100 undergraduate students will participate in an online synchronous crash course and will be randomly assigned to different conditions of the independent variable where they will receive either prompt or delayed feedback …

Exploring A Possible New Mechanism Of The Predictive Coding Theory Of Consciousness With A Binocular Rivalry Experiment, Sai Kiersarsky, Madison Cho-Richmond

Student Research Symposium

Predictive Coding is a theory of brain function in which consciousness is a predictive model generated by higher brain regions that constantly updates its predictions about the cause of upwards flowing data – often sensory perception data. Binocular Rivalry is a phenomenon where, when each eye is presented with a completely different image, consciousness alternates between the images rather than attempting to fuse both images into one.

Here we present the same image to both eyes, but with each image partially blurred in differing areas to test if consciousness weaves together the clear areas to synthesize a single crisp image. …

Portland Urban Coyote Project: A Review Of Citizen Science's Utility For Researching Urban Canids And The Human Environment, Keith David Vanderbrooke

Dissertations and Theses

The Portland Urban Coyote Project (PUCP) is a citizen science project that allows community members to upload coyote (Canis latrans) sighting data to a database that is used to create a public web map; contributors often add observations as well. I analyzed one year of PUCP comment data in order to assess the utility of the citizen science methods used by PUCP for urban carnivore research. I code and summarize findings from PUCP's data, compare the extracted data to other research studies of urban coyote from other regions, and find that results from this analysis supports conclusions made …

Exploring The Correlational Relationship Of Interpersonal Discrimination And Leader-Member Exchange, Bryan Wesley T. Hamilton

Student Research Symposium

Stigmatized individuals use several compensatory strategies to offset the negative impact of interpersonal discrimination in the job application process, including increased positivity, providing individuating information, or identity disclosures. Using interviews and surveys, we aim to expand this literature by examining how these processes unfold after stigmatized individuals have gained employment and are interacting with coworkers. These compensatory strategies can have varying impacts on targets’ workplace relationships, job satisfaction, overall performance, and psychological and physical health outcomes. Leaders and other powerful organizational members can mitigate these negative outcomes and improve employee well being through leader member exchange and perceived supervisor support. …

Does Reading Violent Books Increase Aggression? Perceptions Of An Overlooked Medium, Cassandra H. Muniz

Student Research Symposium

In the ongoing media violence debate, video games, movies, and television are regular targets of scrutiny. Yet, largely absent from the discussion is a popular, age-old medium: the book. Do people think that reading violent subject matter can increase aggression? How do first- and third-person perceptions differ? Using an online survey, the author collected quantitative data on adults’ (N = 160) perceptions of how much violent books affect aggression in themselves, the average adult, and the average child. The author hypothesized that participants would perceive the medium to have stronger effects on other adults' aggression than on their own. …

Boredom And Risk-Taking In Mania, Rose M. Jardine, Nicholas A. Smith

Student Research Symposium

The purpose of this proposal is to examine perceived boredom and risk-taking exhibited during manic episodes in atypical bipolar 1 disorder. I propose to recruit at least 100 participants, ages 18-25, from Intensive Outpatient Programs, Community Programs, and Inpatient Programs who will be verified to be in a manic episode and asymptomatic for psychosis by the on-site providers. A pilot study of two videos will be performed. Participants will be randomly assigned to view one of two videos: “calm” or “exciting”. They will respond to the Boredom Proneness Scale questionnaire at both pre- and post-test as well as the revised …

The Influence Of Surrealist Art On Popular Ads, Sydney G. Thomas Ms.

Student Research Symposium

All ads draw influence from something, most of the time it is from an art movement that will mirror the mental state of the current population. The art influence used for today’s media is surrealist art, due to its chaotic representation of life that mirrors the tumultuous events gen Z and millennials have grown up with. In the surrealist art movement, the general population experienced great anxiety and grappled with the idea of the inner, subconscious self and the represented conscious self. Today, the issue of social media, what is presented compared to what is real, creates an atmosphere where …

Oregon's Racial Purity Regime: The Influence Of International Scientific Racism On Law Enforcement, Legislation, Public Health, And Incarceration In Portland, Oregon During The Victorian And Progressive Eras (1851-1917), Katherine N. Bush

Dissertations and Theses

In 1983, the Oregon State legislature repealed the eugenic sterilization law that had been in use for 60 years. Initially passed during the Progressive era, this law epitomized the State's legacy of surveilling, policing, caging, and inflicting brutality on marginalized and racialized communities who were deemed dangerous, threatening, or contagious. Public health leaders, political officials, law enforcement authorities, and private charities worked together as a multivalent system to maintain racial purity in the State. This racial purity regime drew upon a legacy of international pseudo-scientific racism to justify and bolster policies, legislation, and practices that targeted impoverished communities, people of …

Climatic Controls On The Kinematics Of The Hooskanaden Landslide, Curry County, Oregon, Kara Kingen

Dissertations and Theses

Slow-moving earthflows represent major sources of sediment transport and erosion and are problematic for the management of critical infrastructure. The Hooskanaden Landslide -- a slow-moving earthflow on the southwest coast of Oregon -- crosses US Highway 101 and has been a site of continued interest to the Oregon Department of Transportation (ODOT) due to the weak lithology, erosive environment, and recurrent surge behavior (every ~15 years). Past surges, including the most recent (2019), have occurred during the winter, suggesting that velocity changes are predominantly controlled by climatic inputs. To examine the response of the Hooskanaden Landslide to seasonal and other …

After Aidan: Irish Peregrini And English Ethnogenesis From Aldhelm To Boniface, Jonathan R. Hayes

Phi Alpha Theta Pacific Northwest Regional Conference

The last several decades have seen tremendous interest among Anglo-Saxonists in the points of contact and influence between Irish and Anglo-Saxon clergymen in the seventh and eighth centuries. Yet there has not been a comprehensive synthesis to capture this phenomenon. The present study seeks to consolidate and extend knowledge of Irish-English interactions from Aldhelm to the time of Boniface. Particular attention is given to the Irish practice of peregrinatio pro Christo as a nexus of English fascination. The lasting consequences of these contacts are evaluated, and it is proposed that the concept of the “Angli” as an ecclesiastical and transregional …

The Klondike Gold Rush And The Dead Horse Trail, Brian O'Riley

Phi Alpha Theta Pacific Northwest Regional Conference

Abstract: The Klondike Gold Rush is known in part for the hardships that men and women faced as they travelled the trails to Dawson City in the Yukon. One of the lesser-known aspects of this event is the tragedy that befell thousands of horses that were killed on the Chilkoot and White Pass Trails. The White pass trail would be given the moniker “The Dead Horse Trail.” With so many men trying to get thousands of pounds of goods over the mountain passes from the Alaskan seacoast towns of Skagway and Dyea, pack animals were crucial for the task. However, …
