Despite Similar Perceptions And Attitudes, Postbaccalaureate Students Outperform In Introductory Biology And Chemistry Courses, Erin E. Shortlidge, Liz Rain-Griffith, Chloe Shelby, Gwen Shusterman, Jack Barbera

Biology Faculty Publications and Presentations

Embedding active learning is a common mechanism for meeting science, technology, engineering, and mathematics (STEM) education reform goals. Researchers have identified student benefits from such strategies, yet these benefits may not be universal for all students. We sought to identify how students at a nontraditional university perceive introductory biology and chemistry courses, and whether perceptions relate to course type, performance, or student status. We surveyed students (n = 601) using open-ended prompts regarding their perceptions of factors that impact their learning and interest, and about specific learning strategies. Generally, students did not differ in what influenced their learning or …

Equity In Emergency Management, Sabina Roan, Jaye Cromwell

Metroscape

In the decade following Hurricane Katrina, advocates fighting for the rights of people with disabilities changed the field of emergency management. Their pressure on FEMA led to the establishment of legal and planning precedents to include the needs of the whole community in emergency management.(4) There is now a national, legal requirement to plan for people with disabilities and access and functional needs. Despite this important victory for people with disabilities, there have been no direct legal or policy actions that address the disproportionate response along racial and socio-economic lines.

The theory of social equity has its roots in social …

The Context Of Authority And Sociological Knowledge: An Experiential Learning Project, Julia F. Waity, Stephanie Crowe

Communications in Information Literacy

In this innovative project, a social sciences librarian partnered with a sociology professor to embed the “Authority is Constructed and Contextual” frame into an upper-division sociology of poverty course. Students in this course participated in an experiential learning project, collaborating with local children on a participatory photo mapping project to document the children’s neighborhood. By working directly with community members in this field experience, the students gained an understanding of the differences between scholarly authority and community authority and what can be learned about poverty from each type of source. Engagement with a local community provides students with a direct …

Floodplains Provide Important Amphibian Habitat Despite Multiple Ecological Threats, Meredith Holgerson, Adam Duarte, Marc P. Hayes, Michael J. Adams, Julie A. Tyson, Keith A. Douville, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

Floodplain ponds and wetlands are productive and biodiverse ecosystems, yet they face multiple threats including altered hydrology, land use change, and non-native species. Protecting and restoring important floodplain ecosystems requires understanding how organisms use these habitats and respond to altered environmental conditions. We developed Bayesian models to evaluate occupancy of six amphibian species across 103 off-channel aquatic habitats in the Chehalis River floodplain, Washington State, USA. The basin has been altered by changes in land use, reduced river–wetland connections, and the establishment of non-native American bullfrogs (Rana catesbeiana = Lithobates catesbeianus) and centrarchid fishes, all of which we hypothesized could …

Public transit systems in the USA have been faced with mounting pressure to decrease their operating costs while at the same time expected to increase ridership and meeting multiple societal needs. The primary objective of this study is to measure the efficiencies of mass transit agencies based on best practice in the US, identify the influencing factors leading to their efficiencies, and how these strategies and policies can be used improve inefficiency in transit agencies. Using Data Envelopment Analysis (DEA) method, the study analyzed the mass performance of 334 transit agencies across the US using data from the national transit …

Teaching Race, Racism, And Racial Justice: Pedagogical Principles And Classroom Strategies For Course Instructors, M. Brielle Harbin, Amie Thurber, Joe Bandy

School of Social Work Faculty Publications and Presentations

Teaching on topics of race and racism presents unique challenges to leaders in the university classroom setting. Despite an increasing number of instructors bringing a critical analysis of racial in/justice to their curriculum, many report challenges in teaching this content effectively. In this article, we address these challenges. We define common challenges in teaching racial content and articulate four principles for course planning around topics of race, racism, and racial justice. Then, drawing on a systematic review of scholarship examining issues of difference within a diverse range of disciplinary settings, we introduce a set of five pedagogical strategies, and supporting …

A Comparison Of Neighborhood-Scale Interventions To Alleviate Urban Heat In Doha, Qatar, Salim Ferwati, Cynthia Skelhorn, Vivek Shandas, Yasuyo Makido

Urban Studies and Planning Faculty Publications and Presentations

Recent evidence suggests that many densely populated areas of the world will be uninhabitable in the coming century due to the depletion of resources, climate change, and increasing urbanization. This poses serious questions regarding the actions that require immediate attention, and opportunities to stave off massive losses of infrastructure, populations, and financial investments. The present study utilizes microclimate modeling to examine the role of landscape features as they affect ambient temperatures in one of the fastest growing regions of the world: Doha, Qatar. By modeling three study sites around Doha—one highly urbanized, one newly urbanizing, and one coastal low-density urbanized—the …

Integrating Satellite And Ground Measurements For Predicting Locations Of Extreme Urban Heat, Vivek Shandas, Jackson Lee Voelkel, Joseph Williams, Jeremy Hoffman

Urban Studies and Planning Faculty Publications and Presentations

The emergence of urban heat as a climate-induced health stressor is receiving increasing attention among researchers, practitioners, and climate educators. However, the measurement of urban heat poses several challenges with current methods leveraging either ground based, in situ observations, or satellite-derived surface temperatures estimated from land use emissivity. While both techniques contain inherent advantages and biases to predicting temperatures, their integration may offer an opportunity to improve the spatial resolution and global application of urban heat measurements. Using a combination of ground-based measurements, machine learning techniques, and spatial analysis, we addressed three research questions: (1) How much do ambient temperatures …

Adapting An Elementary School Nutrition Context Assessment For High School Settings And Students, Deborah H. John, Beret Halverson, Tia H. Ho

Urban Studies and Planning Faculty Publications and Presentations

The school nutrition context is comprised of supportive environmental features, programs, policies, and social relationships that shape students’ healthy dietary choices and patterns. When engaging students as change agents, advocates, and partners in making healthy nutrition choices easier, environmental assessment tools developed for adults may be too complex or inappropriately tailored for youth. Adolescents need practical, user-tailored tools that reliably measure the food and beverage environments they encounter in school to inform youth-led changes to the school nutrition context. To meet this need, an evidence-based school environmental assessment was adapted for use in high schools by students as evaluators. Cooperative …

Modeling Changes In Public Transit And Private-For-Hire Usage When Implementing A Spatial Tax, Ty Lazarchik

REU Final Reports

Private-for-Hire (PfH) transportation options, such as Uber, Lyft, and taxicabs, are consistently growing in popularity. With this expanded utilization, cities are struggling to maintain usage of their public transit systems. While PfH transportation has been heavily researched, there is a need to further study how its effects on transit usage may be minimized. In this paper, previous work in traffic modeling and analysis of transit and PfH differences are expanded to develop an agent-based decision model in order to simulate and analyze the effectiveness of implementing a location-based tax in and around the city center of Portland, Oregon. The results …

Simultaneity And Solidarity In The Time Of Permanent War, Marie Lo

English Faculty Publications and Presentations

Excerpt in lieu of abstract:

The war that is going on beneath order and peace, the war that undermines our society and divides it in a binary mode is, basically, a race war.
--Michel Foucault, Society Must Be Defended

In their defense of the Muslim travel ban, lawyers for the Trump administration invoked the plenary power doctrine to justify its legality: "The Order was well under the president's authority under Congress' delegation, particularly in an area like immigration, in which the admission to the United States of foreign aliens is subject to plenary control by the political branches."

Mechanics And Historical Evolution Of Sea Level Blowouts In New York Harbor, Praneeth Gurumurthy, Philip Orton, Stefan A. Talke, Nickitas Georgas, James F. Booth

Civil and Environmental Engineering Faculty Publications and Presentations

Wind-induced sea level blowouts, measured as negative storm surge or extreme low water (ELW), produce public safety hazards and impose economic costs (e.g., to shipping). In this paper, we use a regional hydrodynamic numerical model to test the effect of historical environmental change and the time scale, direction, and magnitude of wind forcing on negative and positive surge events in the New York Harbor (NYH). Environmental sensitivity experiments show that dredging of shipping channels is an important factor affecting blowouts while changing ice cover and removal of other roughness elements are unimportant in NYH. Continuously measured water level records since …

Capturing The Built Environment-Travel Interaction For Strategic Planning: Development Of A Multimodal Travel Module For The Regional Strategic Planning Model (Rspm), Liming Wang, Brian Gregor, Huajie Yang, Tara Weidner, Anthony Knudson

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of …

Characterizing Temperature Variability States Across Southern South America And Associated Synoptic-Scale Meteorological Patterns, Judah Adam Detzer

Dissertations and Theses

The aim of this thesis is to understand spatiotemporal temperature variability in southern South America by identifying overarching temperature variability states and their associated synoptic-scale meteorological patterns. Further, the temporal frequency of occurrence of those temperature variability states is investigated as is the role of recurrent low-frequency modes of climate variability (El Niño Southern Oscillation and the Southern Annular Mode) on temperature variability. K-means cluster analysis is used to group all months during the period 1980-2015 into four primary categories for summer and winter separately. Monthly maps of temperature anomalies are provided as input to the k-means algorithm and the …

Lone Wolves And Copycats: Assessing Policy And Infrastructure For Flood Hazard And Floodplain Management, Samantha L. Hamlin

Dissertations and Theses

To mitigate flood hazard, which affects millions of people every year, increasing numbers of communities are developing green infrastructure policies to not only mitigate the hazard, but to meet other community policy objectives, as green infrastructure is often cited for the multiple benefits it confers. To support the implementation of policies that help communities meet their policy objectives, however, it is imperative to understand how policy is innovated and adopted. To do so, I applied the internal determinants and regional diffusion models, what I refer to as the lone wolf and copycat models. In policy, a lone wolf innovates a …

Interdependent Infrastructure As Linked Social, Ecological, And Technological Systems (Setss) To Address Lock-In And Enhance Resilience, Samuel A. Markolf, Mikhail Chester, Daniel A. Eisenberg, David Iwaniec, Cliff I. Davidson, Rae Zimmerman, Thaddeus R. Miller, Benjamin Ruddell, Heejun Chang

Geography Faculty Publications and Presentations

Traditional infrastructure adaptation to extreme weather events (and now climate change) has typically been techno-centric and heavily grounded in robustness—the capacity to prevent or minimize disruptions via a risk-based approach that emphasizes control, armoring, and strengthening (e.g., raising the height of levees). However, climate and nonclimate challenges facing infrastructure are not purely technological. Ecological and social systems also warrant consideration to manage issues of overconfidence, inflexibility, interdependence, and resource utilization—among others. As a result, techno-centric adaptation strategies can result in unwanted tradeoffs, unintended consequences, and underaddressed vulnerabilities. Techno-centric strategies that lock-in today’s infrastructure systems to vulnerable future design, management, and …

Vehicle Sensor Data (Vsd) Based Traffic Control In Connected Automated Vehicle (Cav) Environment, Xianfeng Terry Yang, Zhao Zhang, Zhehao Zhang

TREC Final Reports

Connected automated vehicles (CAVs) are typically equipped with communication devices (e.g., dedicated short range communications (DSRC)) and on-board sensors (e.g., Radar, Lidar, Camera, etc.). Communication devices would enable the exchange of real-time information between vehicles and infrastructures via vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) channels. Sensors equipped in vehicles are providing various vehicle sensor data (VSD) such as the CAV’s GPS location, speed and moving direction (trajectory). Existing studies have shown the effectiveness of using CAV trajectories as input in many traffic control models.

However, it can be expected that CAVs and human-driven vehicles (HVs) will co-exist on the transportation network …

Engaging Youth To Increase Their Transportation System Support, Understanding, And Use, Autumn Shafer, Jared Macary

TREC Final Reports

Little is known from research about how to motivate youth to choose non-car mobility, especially specific Portland-area youth. Understanding the current attitudes, beliefs, and behaviors of youth in relation to non-car mobility contributes to the sustainability of a long-term transportation system. Transportation system-related beliefs and behaviors of youth are likely to influence their willingness to access and support transportation services as adults. Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. Thus, it is important to develop age-appropriate messaging strategies and tactics that promote youth non-car mobility.

This project seeks to build on the sparse national and non-Portland …

Professional Recruitment Experiences Of Community College Transfer Students Pursuing Accounting At Portland State University, Allison J. Davis

University Honors Theses

Accounting students who transfer to Portland State University (PSU) from a community college are inherently disadvantaged by the structure and timing of the professional recruiting process. This systemic disadvantage has been worsened in the past few years due to CPA firms filling the hiring pipeline earlier with sophomore students. Firms extend early internship offers to many sophomores who attend Summer Leadership Programs^[1] and students who choose to take lower-level courses at community colleges are not naturally made aware of this opportunity until they reach PSU and their window of eligibility has passed. This movement towards earlier recruiting diminishes the …

Scenarios For Adoption Of Autonomous Vehicle Technologies In Freight, Sabya Mishra
