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 …

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 …

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 …

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 …

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. …

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, …

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 …

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 …

The Game Of Life: How Playing Gamified Interactive Narratives Affects Career Planning In Cambodia, Lauren B. Frank, Paul Sparks, Sheila T. Murphy, Lizzie Goodfriend, Paul Falzone

Communication Faculty Publications and Presentations

To improve economic opportunity in Cambodia, we used social cognitive theory to develop gamified, interactive narratives using mobile phones. Participants guided their chosen character toward their “dream job” goal while encountering a series of barriers along the way. Participants (N = 1,625) were randomly assigned to one of four message frequency experimental conditions: a no-play control condition or playing the interactive narrative one, two, or five times. Compared with not playing the interactive narrative (control), those who played showed higher perceived self-efficacy, response efficacy, and behavioral intentions. Playing more times was associated with less attentional focus and enjoyment, but greater …

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.

Remote Reference Consultations Are Here To Stay, Emily Reed

Communications in Information Literacy

Remote reference consultations have considerably increased due to the need to provide remote services during the COVID-19 pandemic. Conducting reference consultations via videoconferencing not only offers many benefits to student researchers it also presents an opportunity for librarians to embrace a learner-centered teaching mindset when approaching remote consultations by developing consultation learning goals in alignment with the Framework for Information Literacy for Higher Education. Designing consultations to be learner-centered yields benefits for students such as the student actively practicing their own searches as well as more thorough source evaluation. Additionally, videoconferencing technology allows for a more seamless information sharing …

Is More Always Better? A Look At Visitation And Recidivism, Teriin Lee

Dissertations and Theses

The body of literature on prison visitation provides empirical support that visitation may influence the likelihood of recidivism. However, the literature is limited in both size and geographic representation, as more than half of studies originate from samples in Florida or Minnesota. Moreover, inconsistency in the use of measures further complicates generalizability of the findings. The following study utilizes data collected from the Oregon Criminal Justice Commission to examine the relationship between visitation and recidivism in Oregon. Using a sample of 29,312 adults in custody (AICs) who were released between 2011 and 2017, we test the associations of seven distinct …

Do Loneliness And Social Isolation Predict Mortality Because Of Hazardous Drinking?, Jussi Tanskanen, Sarah N. Arpin, Cynthia D. Mohr

Psychology Faculty Publications and Presentations

Introduction: Subjective feelings of loneliness and objective social isolation have been consistently connected with ill-health and mortality, though little work has empirically examined the mechanisms explaining the adverse effects. This study examines whether alcohol consumption explains the connection of loneliness and social isolation on mortality in different age and gender groups.

Methods: The sample comprised a representative 1994 Finnish sample (n = 8,650) matched with 22-year follow-up mortality data. A multigroup path analysis with discrete survival time analyses was conducted.

Results: There were unique differences in the associations between loneliness, social isolation, alcohol consumption, and mortality based on age and …

Reflections On Teaching Against White Supremacy During A Time Of Social Rupture And Transformation, Erica Fonesca, Stéphanie Wahab

School of Social Work Faculty Publications and Presentations

Social Justice and Social Work is a foundational course required for all social work students in the master’s of social work program at Portland State University. Although the course has long focused on interrupting oppressions including White supremacy, teaching the course during the fall of 2020 required a nimble dance between our familiar modes of teaching and the need for spontaneous adaptation and creativity. The unique landscape for this course included teaching the course remotely (Zoom), inside a university embattled around the arming of its security force (that killed a Black man in 2018), in a city targeted by an …

Information Literacy For Global Inclusion: Designing An Annotated Bibliography For Global Search And Selection, Pamela A. Espinosa De Los Monteros, Elizabeth L. Black

Communications in Information Literacy

The COVID-19 pandemic has reinforced the notion that our world is global and interdependent. Despite the ever-increasing connection of global with local, there continues to be formidable barriers in accessing information produced in different international contexts and languages. This Innovative Practices article details the redesign of an annotated bibliography assignment in an international studies course to support the inclusion of global perspectives into the information practices of undergraduate students. The redesign embedded explicit information literacy dispositions and global citizenship education competencies through the search and selection of global information sources. The authors discuss the instructional elements used, student outcomes, and …

Spatial Proximity Matters: A Study On Collaboration, Arianna Salazar Miranda, Matthew Claudel

Geography Faculty Publications and Presentations

As scientific research becomes increasingly cross-disciplinary, many universities seek to support collaborative activity through new buildings and institutions. This study examines the impacts of spatial proximity on collaboration at MIT from 2005 to 2015. By exploiting a shift in the location of researchers due to building renovations, we evaluate how discrete changes in physical proximity affect the likelihood that researchers co-author. The findings suggest that moving researchers into the same building increases their propensity to collaborate, with the effect plateauing five years after the move. The effects are large when compared to the average rate of collaboration among pairs of …

Reducing Transphobic Attitudes: A Cross-National Investigation Of College Students In Japan And The United States, Kazusa Seko

Dissertations and Theses

Transgender people routinely experience discrimination and mistreatment. Although transphobic attitudes vary from country to country, a more in-depth understanding of these attitudes is needed. Using a semi-structured online survey, this study investigates college students' attitudes toward transgender people in Japan and the United States, a cross-national comparison that aims to deepen our understanding of how transphobic attitudes are shaped and what opportunities exist to reduce transphobia amongst college students. Results show that Japanese students express more transphobic attitudes than U.S. students do; and that U.S. students had more experience with gender-based educational content and were more likely to know someone …

How Has Cultural Marxism Been Used As A Political Tactic In Order To Decrease Trust In Higher Education?, Drew Havnaer

University Honors Theses

This thesis will address the rise in popularity of the political notion of the 'Culture War.' It will trace this theory from its origins in the mid-20th century, through the landmark 1993 Buchanan Culture War speech, and to a modern version, often referred to as the theory of Cultural Marxism. The first part of the argument identifies employment of this theory by modern conservatives, and analyzes how many of us encounter it in our daily life, most prominently in reference to higher education. The second part of the argument targets the effect in colleges and universities specifically. It identifies how …

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 …
