Microplastics In Freshwater: A Global Review Of Factors Affecting Spatial And Temporal Variations, Rebecca Talbot, Heejun Chang

Geography Faculty Publications and Presentations

Microplastics are a pollutant of growing concern, capable of harming aquatic organisms and entering the food web. While freshwater microplastic research has expanded in recent years, much remains unknown regarding the sources and delivery pathways of microplastics in these environments. This review aims to address the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. A total of 75 papers, published through June 2021 and containing an earliest publication date of October 2014, was identified by a Web of Science database search. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations …

Tools For Addressing Intimate Partner Violence And Suicide Risk: Lessons Learned From Oha’S Covid-19 Emergency Response For Suicide Prevention Grant, Karen Cellarius, Aliza Tuttle, Lea Sevey

Regional Research Institute for Human Services

In August 2020, the Oregon Coalition Against Domestic and Sexual Violence (OCADSV), the Oregon Health Authority (OHA), and Portland State University’s Regional Research Institute for Human Services (PSU RRI) began an 18-month collaboration to strengthen support for domestic violence and mental health agencies during COVID-19. As part of this grant, six domestic violence advocacy organizations around Oregon were able to place co-located advocates with their mental health partner agencies for services and cross-training. The content of this booklet is another product of this collaboration.

Introduction: Climate Change And Planned Retreat, Idowu Jola Ajibade, A. R. Siders

Geography Faculty Publications and Presentations

Chapter 1.

This edited volume advances our understanding of climate relocation (or planned retreat), an emerging topic in the fields of climate adaptation and hazard risk, and provides a platform for alternative voices and views on the subject. As the effects of climate change become more severe and widespread, there is a growing conversation about when, where and how people will move. Climate relocation is a controversial adaptation strategy, yet the process can also offer opportunity and hope. This collection grapples with the environmental and social justice dimensions from multiple perspectives, with cases drawn from Africa, Asia, Australia, Oceania, South …

Changes To California Alfalfa Production And Perceptions During The 2011-2017 Drought, Alida A. Cantor, Bethani Turley, Charles Cody Ross, Mathern Glass

Geography Faculty Publications and Presentations

California experienced a severe multiyear drought stretching from 2011 through 2017, significantly reducing surface water supply for ecosystems, agriculture, and humans and prompting coordinated conservation efforts. Given that agriculture is the largest consumptive use of water in the state, one anticipated response to a severe drought would be to decrease production of low-value, high-water-use crops such as alfalfa. In this article we use a multimethod approach to examine both spatial distribution and public perceptions of alfalfa production in California over the course of the 2011 through 2017 drought. We find that although California alfalfa production did decline at the state …

Oregon Statewide Homelessness Estimates 2021, Timothy Green, Marisa Zapata, Jacen Greene

Homelessness Research & Action Collaborative Publications and Presentations

Executive Summary This report, prepared by Portland State University’s Homelessness Research and Action Collaborative (PSU-HRAC) at the request of Oregon Housing and Community Services, provides estimates of people experiencing sheltered and unsheltered homelessness in 2021 at the state, county, and Continuum of Care (CoC) levels. Trends and demographics are also analyzed at those levels to the extent possible given the limitations of available data.

In 2021, Oregon Continuums of Care (CoCs) in charge of administering Point-in-Time (PIT) counts of people experiencing literal homelessness1 faced the unprecedented challenge of doing so in the midst of a major global pandemic. Some CoCs …

Oregon's Safe Harbor For Tenants: Rocky Shoals In Eviction Diversion, Lisa K. Bates

Homelessness Research & Action Collaborative Publications and Presentations

In an effort to mitigate the impacts of the Covid-19 public health emergency, throughout 2020 and into 2021 novel public health emergency programs were initiated, including a variety of federal, state, and local ‘moratoriums’ on residential evictions for nonpayment of rent. As the moratoria began to sunset, additional ‘post-pandemic’ eviction diversion and tenant protection programs were created to buffer the ‘tsunami’ of evictions that were expected.

Oregon’s eviction diversion program, the so-called ‘safe harbor period’ for nonpayment eviction cases, was put into place in July 2021 to maintain some protections for tenants after the state moratorium on nonpayment evictions ended. …

Village Research & How-To Guide, Todd Ferry, Greg Townley, Marisa Zapata

Homelessness Research & Action Collaborative Publications and Presentations

The village model is an increasingly popular form of alternative shelter being explored by organizations, activists, and municipalities around the country. Portland’s Dignity Village is the country’s first and longest running village, serving as a touchstone for community dialogue in Oregon around the subject of supporting people experiencing homelessness since 2000. More recently, the region has seen the rapid increase in alternative shelters informed by or following the village model, sparked by a state of emergency declaration on housing and homelessness in Portland in 2015, and further accelerated by the COVID-19 pandemic. As the model continues to grow and morph …

Working With Others In The Mentoring Relationship System, Thomas E. Keller

School of Social Work Faculty Publications and Presentations

A mentoring relationship typically doesn’t operate in isolation. Even youth who want or need additional support from a mentor are bound to have many other important people in their lives, such as parents and other caregivers, siblings, teachers, and peers. Consequently, a mentor already may have or may need to establish relationships with other people in the mentee’s network of support. Because these other individuals, and a mentor’s interactions with them, have the potential to enhance or detract from the mentoring experience, they are all important parts of the “mentoring relationship system.”

This chapter outlines important considerations for how to …

Getting Proactive With Police Proactivity: The Benefits Of Computer-Aided Dispatch For Directing Police Resources To Areas Of Need, Kris Henning, Christian Peterson, Greg Stewart, Kimberly Kahn, Yves Labissiere, Brian Renauer, Renee Mitchell, Sean Sothern

Criminology and Criminal Justice Faculty Publications and Presentations

Sherman and colleagues (2014) argue that crime reductions associated with hot spot policing can be maximized by carefully managing the dosage of supplemental resources delivered. Fully achieving this goal in prior studies has been difficult due to resistance by officers, the use of atypical strategies for directing patrols to target locations, and insufficient attention to the measurement of treatment dosages. This has led to calls for process research examining the implementation of hot spot policing in law enforcement agencies. The current study represents one such effort. The computer-aided dispatch (CAD) system for a large U.S. police department was pre-programmed with …

Patterns Of Interdisciplinary Collaboration Resemble Biogeochemical Relationships In The Mcmurdo Dry Valleys, Antarctica: A Historical Social Network Analysis Of Science, 1907–2016, Stephen M. Chignell, Adrian Howkins, Poppie Gullett, Andrew G. Fountain

Geology Faculty Publications and Presentations

Co-authorship networks can provide key insights into the production of scientific knowledge. This is particularly interesting in Antarctica, where most human activity relates to scientific research. Bibliometric studies of Antarctic science have provided a useful understanding of international and interdisciplinary collaboration, yet most research has focused on broad-scale analyses over recent time periods. Here, we take advantage of a ‘Goldilocks’ opportunity in the McMurdo Dry Valleys, an internationally important region of Antarctica and the largest ice-free region on the continent. The McMurdo Dry Valleys have attracted continuous and diverse scientific activity since 1958. It is a geographically confined region with …

Assessment Of Vertical Accuracy From Uav-Lidar And Structure From Motion Point Clouds In Floodplain Terrain Mapping, Andrew Muller

Dissertations and Theses

Remote sensing technologies are being applied to a variety of uses because of the increase in access to various products (digital sensors, UAVs, software) and its ability to model relatively large areas in a short amount of time. While these new technologies are beginning to be adopted, validation of their merit in floodplain terrain mapping is lacking. The main goal of this study is to evaluate the vertical accuracy of digital elevation models (DEMs) generated with UAV-based LiDAR and Structure from Motion (SfM), also known as photographic LiDAR or PhoDAR. Airborne (manned aircraft) LiDAR has been applied to river research …

Colonial Necrocapitalism, State Secrecy, And The Palestinian Freedom Tunnel, Nadera Shalhoub-Kevorkian, Stephanie Wahab

School of Social Work Faculty Publications and Presentations

Secrecy and the use of “secret information” as capital in the hands of the state is mobilised by affective racialised machineries, cultivated on “security” grounds. Securitised secrecy is an assemblage of concealed operations juxtaposing various forms of invasions and dispossessions. It is a central strategy in the politico-economic life of the state to increase its scope of domination. Secrecy is used and abused to entrap and penetrate political subjects and entities. This article explores the necrocapitalist utilisation of secrecy embedded in the coloniser’s attempt to distort the mind of the colonised. Built from the voices of those affected by secrecy’s …

Mass Timber Building Life Cycle Assessment Methodology For The U.S. Regional Case Studies, Hongmei Gu, Shaobo Liang, Francesca Pierobon, Maureen Puettmann, Indroneil Ganguly, Cindy Chen, Rachel Pasternack, Mark Wishnie, Susan Jones, Ian Maples

Publications, Reports and Presentations

The building industry currently consumes over a third of energy produced and emits 39% of greenhouse gases globally produced by human activities. The manufacturing of building materials and the construction of buildings make up 11% of those emissions within the sector. Whole-building life-cycle assessment is a holistic and scientific tool to assess multiple environmental impacts with internationally accepted inventory databases. A comparison of the building lifecycle assessment results would help to select materials and designs to reduce total environmental impacts at the early planning stage for architects and developers, and to revise the building code to improve environmental performance. The …

Comparative Lcas Of Conventional And Mass Timber Buildings In Regions With Potential For Mass Timber Penetration, Maureen Puettmann, Francesca Pierobon, Indroneil Ganguly, Hongmei Gu, Cindy Chen, Shaobo Liang, Susan Jones, Ian Maples, Mark Wishnie

Publications, Reports and Presentations

Manufacturing of building materials and construction of buildings make up 11% of the global greenhouse gas emission by sector. Mass timber construction has the potential to reduce greenhouse gas emissions by moving wood into buildings with designs that have traditionally been dominated by steel and concrete. The environmental impacts of mass timber buildings were compared against those of functionally equivalent conventional buildings. Three pairs of buildings were designed for the Pacific Northwest, Northeast and Southeast regions in the United States to conform to mass timber building types with 8, 12, or 18 stories. Conventional buildings constructed with concrete and steel …

Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys

Dissertations and Theses

Antipsychotic medication use (APU) in assisted living and residential care (AL/RC) settings is an under-studied and controversial health policy issue. APU in older adults with dementia is associated with an increased risk of falls, hospitalizations, and early mortality. I operationalize the Institutional Analysis and Development Framework using a situational analysis approach, an extension of grounded theory methods, to explore the APU in Oregon AL/RC settings. Regulatory deficiency citations, Oregon AL/RC population data, and semi-structured interviews suggest that staff role clarity, organizational characteristics, and perceived agency influence decision-making around APU. AL/RC providers and caregivers are forced to simultaneously balance and prioritize …

An Examination Of Nurses' Schedule Characteristics, Recovery From Work, And Well-Being, Sarah Elizabeth Van Dyck

Dissertations and Theses

Recovery from work refers to the replenishment of energetic and affective resources depleted while meeting job demands, predominately conceptualized as a process that unfolds throughout the day. This study examined the shift work schedule demands presented by round-the-clock patient care needs on health care providers, and potential recovery opportunities during mid-shift meal and rest breaks. The cross-sectional data were collected via electronic questionnaire among registered nurses (N = 134) working in direct patient care roles in 24-hour healthcare organizations in the Northwestern United States (91.0% female-identified; mean age = 45.3 years). The main effects of adverse scheduling characteristics common …

Nature-Based Solutions In Environmental Planning: Ecosystem-Based Adaptations, Green Infrastructures, And Ecosystem Services To Promote Diversity In Urban Landscapes, Lorena Alves Carvalho Nascimento

Dissertations and Theses

Nature-based solutions encompass strategies that explore ecosystem-based adaptations, green infrastructures, and ecosystem services in environmental planning and landscape management. However, nature-based solutions do not always consider ecological values and perspectives from Black, Indigenous, and Global South population. This dissertation has three independent papers that explore the application of ecosystem-based adaptations, green infrastructures, and ecosystem services in communities unheard by environmental planning agencies. The first paper is a conceptual framework that used literature review and observations of current human-nature interactions to reflect how the criminalization, acculturation, and cultural appropriation of cultural ecosystem services have burdened Black and Indigenous identities. Recommendations for …

Working Paper No. 53, Mexico Under Neoliberalism, Daniela M. Ávila Arévalo

Working Papers in Economics

This inquiry seeks to establish that a set of policies that can be identified as ‘neoliberalism’ has generated observable effects on the economy and society of Mexico. Initiated during the last decades of the twentieth century, a combination of external and internal interests led to the implementation of neoliberal policies. The marketization of Mexico’s economy during the 1980s and 90s consolidated ‘structural adjustments.’ Through extensive privatization of what were statist assets, combined with the deregulation of trade as well as numerous aspects of private sector activity, the Mexican economy came to rely upon a low-wage labor export-model that also undermined …

Working Paper No. 60, The Importance Of Industrial Hemp In The Early United States, Olivia Carrillo

Working Papers in Economics

This inquiry seeks to establish that in the early United States industrial hemp emerged as an important crop. In Colonial America, hemp was a desirable commodity that attracted capital investments into its cultivation and processing. Because of its durability and strength, hemp fibers had substantial worth in the production of thread, rope, and heavy canvas. Not only was the cultivation of hemp important for the development of a variety of household products, but hemp also played a military role, as the hemp fibers were spun, woven, and fashioned into sails that provided wind power for commercial and military navies. However, …

Working Paper No. 57, The Plight Of The Indigenous In British North America, Maria Nicolas-Reyes

Working Papers in Economics

This inquiry seeks to establish that the Indigenous population of North America experienced a tragic fate as a result of British colonization and American dominance. Upon the arrival of the English colonists, infectious diseases spread rapidly, disrupting Native American’s way of life and also decimating their populations. This inquiry examines two geographic areas—Virginia’s Eastern Shore and the Midcontinent—in order to demonstrate how these diseases affected Native Americans differently. Aside from the negative effects of the introduction of new infectious diseases, Indigenous peoples endured genocide perpetrated by English settlers as a means to gain greater control of their lands. Lastly, Indigenous …

Counselor Education Faculty Publications and Presentations

Objective: Patients with rheumatoid arthritis (RA) often suffer from bone complications due to persistent joint inflammation, especially incident fracture. Nowadays, Chinese herbal medicines (CHMs) have provided safe and effective therapy for treating skeletal conditions, but it is unclear whether CHMs can prevent fracture onset among RA individuals. This study aimed to determine the association between the use of CHMs and the risk of fracture among them.

Methods: This retrospective, population-based study retrieved administrative health data from the Taiwan National Health Insurance (NHI) database to identify patients with newly diagnosed RA between 2000 and 2009. Of the 6178 incident …

Practice Research Methods In Social Work: Processes, Applications And Implications For Social Service Organisations, Bowen Mcbeath, Michael J. Austin, Sarah Carnochan, Emmeline Chuang

School of Social Work Faculty Publications and Presentations

Although social work research is commonly rooted within social service settings, it can be difficult for social work researchers and practitioners to develop and sustain participatory studies that specifically promote knowledge sharing and service improvement involving organisational practice. One participatory approach is practice research (PR), which involves social work researchers and practitioners collaborating to define, understand and try to improve the delivery of health and social care services and organisational structures and processes. The two goals of this commentary are to introduce essential methods and approaches to PR and to identify points of connection involving PR and social service organisational …

Collaborative Digital Problem-Solving: Power, Relationships, And Participation, Gloria E. Jacobs, Jill Castek

Applied Linguistics Faculty Publications and Presentations

The study examines the collaborative nature of problem solving as dyads and triads of adults were grouped to solve digital problems using online resources. Digital problem solving involves the nimble use of skills, strategies, and mindsets to navigate online in everyday contexts using novel resources, tools, and interfaces, in efficient and flexible ways, to accomplish personal and professional goals. Findings address the nature of collaborative talk during digital problem solving through three interrelated categories of themes gleaned from discourse analysis: (a) power, (b) relationships, and (c) participation. These themes offer a nuanced understanding of collaborative interactions during digital problem solving. …

Parenting And Children's Academic Coping As A Dynamic System: Feedforward, Feedback, And Mediators Of Changes Across The School Year, Kristen Elizabeth Raine

Dissertations and Theses

Using a motivational framework based in self-determination theory, the present study investigated the dynamic system between parenting and children's coping, defined as the ways they handle the everyday difficulties they encounter in school, using a sample of 1,020 students in grades three through six drawn from a larger cohort-sequential study. Three overarching research questions were examined using multiple regression that concerned 1) feedforward effects from parents' initial provision of motivational support (i.e., involvement, structure, and autonomy support) to changes in children's academic coping across the school year, 2) feedback effects from children's initial coping to changes in the same parenting …

Sustaining Boys' Motivation Over The Transition To Middle School: Can Interpersonal Resources Protect Boys From Engagement Declines Across Sixth Grade?, Brandy Anne Brennan

Dissertations and Theses

Recent research has highlighted the challenges boys face in school. Boys are overrepresented on indicators of negative academic outcomes, such as detention, suspension, and dropout, as well as underperformance on state and national tests. Moreover, these effects may be long lasting: Compared to females, male students are less likely to graduate high school, enroll in college, and complete a college degree, and they may be particularly vulnerable in middle school. As students enter middle school, their motivation and engagement normatively decline, and these losses may be especially problematic for boys. Nevertheless, research documents the importance of close relationships with parents, …

A New Approach To Transportation Pricing: Lessons From The Poem Project, Shoshana Cohen, Emma Sagor

PSU Transportation Seminars

In October 2021, Portland City Council accepted the Pricing Options for Equitable Mobility (POEM) report. This was the culmination of 18 months of work by the POEM Task Force, a group of 19 volunteer community members who explored whether pricing tools—or charges related to driving or using road space—could be used to improve mobility, reduce climate impact, and make our transportation system more equitable. More information is available at Portland.gov/POEM.

At this seminar, POEM Project Managers Shoshana Cohen and Emma Sagor from the Portland Bureau of Transportation (PBOT) will share how this project took on the topic of …

How Peer Mentoring Can Help Universities Promote Student Success In A Post-Covid-19 Pandemic World, Peter J. Collier

Sociology Faculty Publications and Presentations

The COVID -19 pandemic and fallout from universities’ pandemic response efforts has made the adjustment to college more complex for new students. This is particularly true for students who lack familiarity with how college works. In addition to student adjustment issues, new pandemic -related issues include a greater risk for information overload, problematic access to technology and the Internet, more complicated decision making, greater difficulty in recognizing relevant resources and effective strategies for addressing specific issues, and difficulties in responding to issues that take different forms in remote or hybrid learning contexts. Peer mentoring can help. Informed by interviews with …

Beam Me Up: Teaching Rhetorical Methods For Source Use And Synthesis, Ashley Roach-Freiman

Communications in Information Literacy

BEAM is a schema for categorizing the rhetorical positions of authors according to the author’s intention or purpose of the information. The author critiques common methods of teaching source evaluation and proposes that instruction librarians teach BEAM to students who may struggle using a source once they have located it. A lesson plan is included as supplemental materials.

Can A Large-Landscape Conservation Vision Contribute To Achieving Biodiversity Targets?, Mark Hebblewhite, Jodi A. Hilty, Sara Williams, Harvey Locke, Charles Chester, David Johns, Gregory Kehm, Wendy L. Francis

Political Science Faculty Publications and Presentations

Founded in 1993, the Yellowstone to Yukon (Y2Y) vision was one of the earliest large-landscape conservation visions. Despite growing recognition of large-landscape conservation strategies, there have been few tests to date of conservation gains achieved through such approaches. We tested for conservation gains in the Y2Y region of North America following initiation of the Y2Y conservation vision in 1993 using a counterfactual spatiotemporal comparison and tracking change in five different conservation metrics. First, we enumerated the area of land within Y2Y in designated protected areas. We then compared the rate of change of protected area growth before- and after-initiation of …
