Can We Do Better Next Time? Italians’ Response To The Covid-19 Emergency Through A Heuristics And Biases Lens, Raffaella Misuraca, Ursina Teuscher, Costanza Scaffidi Abbate, Francesco Ceresia, Michelle Roccella, Lucia Parisi, Luigi Vetri, Silvana Miceli

Psychology Faculty Publications and Presentations

During the outbreak of COVID-19 in Italy, people often failed to adopt behaviors that could have stopped, or at least slowed down, the spread of this deadly disease. We offer cognitive explanations for these decisions, based on some of the most common heuristics and biases that are known to influence human judgment and decision-making, especially under conditions of high uncertainty. Our analysis concludes with the following recommendations: policymakers can and should take advantage of this established science, in order to communicate more effectively and increase the likelihood that people choose responsible actions in a public health crisis.

A New Agent-Based Model Offers Insight Into Population-Wide Adoption Of Prosocial Common-Pool Behavior, Garry Sotnik, Thaddeus Shannon, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

New theoretical agent-based model of population-wide adoption of prosocial common-pool behavior with four parameters (initial percent of adopters, pressure to change behavior, synergy from behavior, and population density); dynamics in behavior, movement, freeriding, and group composition and size; and emergence of multilevel group selection. Theoretical analysis of model’s dynamics identified six regions in model’s parameter space, in which pressure-synergy combinations lead to different outcomes: extinction, persistence, and full adoption. Simulation results verified the theoretical analysis and demonstrated that increases in density reduce number of pressure-synergy combinations leading to population-wide adoption; initial percent of contributors affects underlying behavior and final outcomes, …

For Better And Worse: How Proactive Personality Alters The Strain Responses To Challenge And Hindrance Stressors, Jordan Nielsen, Brady M. Firth, Eean Crawford

Business Faculty Publications and Presentations

Employees with a proactive personality tend to show exceptional initiative and perseverance, suggesting that they are relatively impervious to stressors. Yet some evidence suggests that proactive personality may exacerbate the effect of stressors on strain. In this study, we clarify these conflicting ideas by systematically distinguishing between different types of chronic work stressors. Integrating the conservation-of-resources model and the challenge–hindrance stressor framework, we suggest that employees with more proactive personalities are especially sensitive to the extent to which chronic work stressors are amenable to their resource investments. Specifically, we hypothesize that, for more proactive employees, challenge stressors (opportunities more amenable …

Reckoning With Induced Vehicle Travel, Jamey Volker

PSU Transportation Seminars

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or misestimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, …

New Opportunities And Untapped Scientific Potential In The Abyssal Ocean, Jeffrey J. Marlowe, Rika E. Anderson, Anna-Louise Reysenbach, Jeffrey S. Seewald, Timothy M. Shank, Andreas P. Teske, V. Dorsey Wanless, S. Adam Soule

Biology Faculty Publications and Presentations

The abyssal ocean covers more than half of the Earth’s surface, yet remains understudied and underappreciated. In this Perspectives article, we mark the occasion of the Deep Submergence Vehicle Alvin’s increased depth range (from 4500 to 6500 m) to highlight the scientific potential of the abyssal seafloor. From a geologic perspective, ultra-slow spreading mid-ocean ridges, Petit Spot volcanism, transform faults, and subduction zones put the full life cycle of oceanic crust on display in the abyss, revealing constructive and destructive forces over wide ranges in time and space. Geochemically, the abyssal pressure regime influences the solubility of constituents such as …

An Automated Zoom Class Session Analysis Tool To Improve Education, Jack Arlo Cannon Ii

Dissertations and Theses

The recent shift towards remote education has presented new challenges for instructors with respect to teaching evaluation. Students in traditional classrooms send signals to instructors which provide feedback for the effectiveness of a given lecture. Virtual learning environments lack some of these communication channels and require new ways of collecting feedback. This work presents a suite of analysis tools for the virtual instructor. Given the transcript and video files for a Zoom meeting, this tool summarizes student sentiment and speaking characteristics. Sentiment scores are derived using state of the art Natural Language Processing (NLP) models. The video file is used …

Space And Identity In J.M. Coetzee's Life & Times Of Michael K, Joshua Baker

University Honors Theses

Occupying colonial governments establish and maintain power through the demarcation and control of space, a process Sara Upstone terms "overwriting". In Life & Times of Michael K, Coetzee imagines the complication of establishing and maintaining a self-identity amid the strict control of space in post-apartheid, wartime South Africa, and it is this conflict of identity which comprises the novel’s subplot. The reader follows Michael K's odyssey over hundreds of miles in his quest to find the farm on which his mother was born and raised. His journey is repeatedly thwarted by state actors who enforce a strict control of movement …

Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Sadegh Sabouri, Justyna Kaniewska, Hassan Ameli, Wookjae Yang, Fatemeh Kiani, Junsik Kim, Douty Chibamba

TREC Final Reports

The transportation and land use planning paradigm is shifting away from segregated uses connected by highways and roads to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought transit-oriented development (TOD) to the fore, and researchers continue to highlight advantages of this style of well-integrated land use and transportation planning. When it comes to affordability, what counts isn’t housing costs alone but the combination of housing plus transportation costs (H+T). If TODs do, in fact, command higher rents due to increased transit accessibility, this creates an issue of social equity, especially if higher housing costs are …

Understanding The Impact Of Decentralizing Homeless Services On Transportation And Mobility In Salt Lake County, Sarah L. Canham, Jeff Rose, Ivis Garcia Zambrana, Shannon O. Jones

TREC Final Reports

In 2019, the delivery of homeless sheltering services in Salt Lake County transitioned from a centralized emergency shelter—The Road Home Salt Lake Community Shelter and Resource Center (TRHSLC)—operated by The Road Home to a decentralized, scattered site model with multiple “Homeless Resource Center” (HRC) locations operated by multiple service providers. To understand to what degree and to which “proximity” to public transportation and other needed services was achieved, this study examined: 1) how the decentralization of homeless services influenced transportation demand and mobility patterns for persons experiencing homelessness (PEH); and 2) how transportation and mobility changes affected access to services …

Scooting To A New Era In Active Transportation:Examining The Use And Safety Of E-Scooters, Kristina M. Currans, Nicole Iroz-Elardo, Reid Ewing, Dong-Ah Choi, Brandon Siracuse, Torrey Lyons, Quinton Fitzpatrick, Julian Griffee

TREC Final Reports

The modern transportation paradigm is an ever-shifting target and, most recently, micro-mobility options such as electric shared scooter systems (e-scooters) have been contributing to local municipalities’ ability to adapt. Although several agencies have moved towards a “regulate-pilot-evaluate-revise” approach to addressing the transformative technologies of e-scooters, the seemingly overnight proliferation of this new mode in urban areas has brought a great deal of discussion about how this technology is (and should be) used by the consumer. Safety considerations for both e-scooter and conventional transportation mode users is of great concern to planners and decision makers. It is important to understand the …

How Affordable Is Housing In Transit-Oriented Developments?, Reid Ewing, Nicole Iroz-Elardo, Arlie Adkins

TREC Project Briefs

Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change?

Is Transit-Oriented Development Affordable for Low and Moderate Income Households?, a study funded by the National Institute of Transportation and Communities (NITC), examines housing costs for households living in TODs. Led by Reid Ewing …

Optimizing Housing And Service Locations To Provide Mobility To Meet The Mandated Obligations For Former Offenders To Improve Community Health And Safety, Anne Nordberg, Jaya Davis, Stephen Mattingly, Sarah R. Leat, Mansi Patel, Michael Mitchell, Santhosh Medeti, Craig Keaton, Jobaidul Boni, Jhanvi Manishkum, Alireza Fallahi, Sheida Khademi

TREC Final Reports

Roughly 2,000 inmates return to communities each day in the U.S. Unsuccessful reentry jeopardizes community safety, promotes re-incarceration, and increases costs to taxpayers to support the criminal justice apparatus. Research indicates that strong networks of support reduce recidivism, but most communities remain ill-equipped to successfully support former offenders. Our community partner, Unlocking DOORS in Dallas, TX, is a reentry brokerage firm that coordinates services including housing, mental and physical health services, job retraining, transportation, and parole or probation obligations. This, like most reentry service providers, assists former offenders navigating a patchwork of logistical hurdles including individual offender obligations, scarce offender …

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience and to develop forms of assistance or educational strategies to fill the varying mobility gaps and meet the mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys and interviews collected from community-dwelling older adults in Dallas, Texas. Through the interview during the pandemic, the research team found that perceptual and knowledge barriers appear to be reduced among older adults …

Temperature And Predator Effects On Green Crabs (Carcinus Maenas) And Their Distribution In South Slough National Estuarine Research Reserve, Elissa Connolly-Randazzo

Dissertations and Theses

The invasive green crab (Carcinus maenas) has increased in abundance and distribution among Oregon's estuaries. Its global success in establishing in new environments and tolerance for abiotic stressors, such as temperature, raises concern for C. maenas to negatively influence native crab species, especially given global climate change. To improve in predicting invasion impacts, this work analyzed the results from a controlled tank experiment at Portland State University and the field data on a population of C. maenas in South Slough National Estuarine Research Reserve (SSNERR). The aquarium experiment documented predation pressure on C. maenas across a range of …

Psu Student Research From The Trb 2022 Annual Meeting: Effect Of Covid-19 On Property Value Premium Of Light Rail Transit, Sangwan Lee

PSU Transportation Seminars

The COVID-19 pandemic has impacted health and transformed many aspects of our lives, such as travel behavior and residential location preference. For instance, since the outbreak, there was a sharp decline in the ridership of public transportation. Moreover, since the pandemic, a shifting preference toward suburban and exurban areas from denser urban areas like Central Business Districts has been reported. Accordingly, a question arises whether the plummeted transit ridership, alongside the anecdotal and empirical evidence that some households prefer to disperse away from the cities, could combine to transform the long-standing housing price mechanism related to transit proximity. Thus, we …

Psu Student Research From The Trb 2022 Annual Meeting: Drone Facility Location Considering Coverage Reliability: Application To Emergency Medical Scenarios, Darshan Chauhan

PSU Transportation Seminars

Public service agencies like hospitals, fire, rescue, and police departments are required to maintain a high level of service. These service standards often come as reliability constraints. For example, fire-related incidents require a 90% response rate in 4 minutes. We consider a case study of tackling out-of-hospital cardiac events using AED-enabled drones in Portland, OR. Environmental factors, majorly wind speed and direction, significantly impact drone performance. We formulate the drone location problem as a robust multi-period maximum coverage facility location problem. We model the coverage reliability constraint as a chance constraint on failure probabilities. For our context, multiple periods translate …

The Impact Of New Light Rail Service On Employment Growth In Portland, Oregon, Lahar Santra

Dissertations and Theses

This study quantitatively examines the impact of the new Light Rail Transit (LRT) service on employment growth in retail, knowledge, and service sectors before and after opening the LRT. At the corridor level, this study conducts a case study of Greenline in Southeast Portland, Oregon. The results of the corridor level study suggest that the new LRT service increased employment along the Greenline corridor among all the three sectors of interest- retail, knowledge, service in the long-term (ten years) while having slightly different results for the short-term (five years), likely due to the slow growth of LRT benefits. This study …

Spatial And Seasonal Variations Of Microplastic Concentrations In Portland's Freshwater Ecosystems, Rebecca Talbot

Dissertations and Theses

Microplastics are a pollutant of growing concern and are ubiquitous in a variety of environmental compartments. The majority of microplastics research to date has been conducted in marine waters, and less is known regarding the sources and delivery pathways of microplastics in urban rivers. The first chapter is comprised of a review of the scientific literature regarding the spatial and temporal factors affecting global freshwater microplastic distributions and abundances. Microplastic spatial distributions are heavily influenced by anthropogenic factors, with higher concentrations reported in regions characterized by urban land cover, high population density, and wastewater treatment plant effluent. Temporal variables of …

The New Shiny Penny? Regenerative Agriculture Beliefs And Practices Among Portland's Urban Agriculturalists, Melia Ann Chase

Dissertations and Theses

Regenerative agriculture (RA) is a set of farming and land management practices intended to support or enhance soil health and carbon sequestration potential of soils while producing food, fiber, or other agricultural products. It has received broad acclaim from scholars, corporations, and governmental bodies as a potential means of sequestering carbon and mitigating climate change impacts. It has also received critique and pushback for its vague definition, shifting metrics, and lack of acknowledgement of the Indigenous practices underlying the modern suite of regenerative practices. The purpose of this research is to investigate the beliefs Portland, Oregon urban agricultural practitioners hold …
