A Comprehensive Examination Of Electronic Wayfinding Technology For Visually Impaired Travelers In An Urban Environment, Martin Swobodzinski, Amy T. Parker

TREC Final Reports

In this project, we distilled an inventory of smartphone-based electronic travel aid technology for the wayfinding of visually impaired travelers in an urban environment based on a thorough review of software marketplaces and the academic literature. Subsequently, we solicited structured input from domain experts and visually impaired individuals on their experiences and evaluations pertaining to personal telecommunication technology for safe and efficient wayfinding. The insights gained from this project are instrumental for the conceptualization and development of integrated route planning and guidance application that address the distinct information needs and expectations of individuals with a vision-related functional impairment. The very …

Factors Influencing The Use Of Cognitive-Behavioral Therapy With Autistic Adults: A Survey Of Community Mental Health Clinicians, Brenna B. Maddox, Samantha Crabbe, Jessica Fishman, Rinad S. Beidas, Lauren Brookman-Frazee, Judith Miller, Christina Nicolaidis, David Mandell

School of Social Work Faculty Publications and Presentations

Cognitive–behavioral therapy (CBT) can improve anxiety and depression in autistic adults, but few autistic adults receive this treatment. We examined factors that may influence clinicians’ use of CBT with autistic adults. One hundred clinicians completed an online survey. Clinicians reported stronger intentions (p = .001), more favorable attitudes (p < .001), greater normative pressure (p < .001), and higher self-efficacy (p < .001) to start CBT with non-autistic adults than with autistic adults. The only significant predictor of intentions to begin CBT with clients with anxiety or depression was clinicians’ attitudes (p < .001), with more favorable attitudes predicting stronger intentions. These findings are valuable for designing effective, tailored implementation strategies to increase clinicians’ adoption of CBT for autistic adults.

Autistic adults have high rates of anxiety and depression (Buck et al. 2014; Croen et al. 2015), and often do not receive quality mental healthcare for these or other co-occurring conditions (Maddox et al. 2019; Roux et al. 2015; Shattuck et al. …

Understanding Factors Affecting Arterial Reliability Performance Metrics, Jason C. Anderson, Rohan Sirupa, Sirisha Kothuri, Avinash Unnikrishnan

TREC Final Reports

In recent years, the importance of travel time reliability has become equally important as average travel time. However, the majority focus of travel time research is average travel time or travel time reliability on freeways. In addition, the identification of specific factors (i.e., peak hours, nighttime hours, etc.) and their effects on average travel time and travel time variability are often unknown. The current study addresses these two issues through a travel time-based study on urban arterials. Using travel times collected via Bluetooth data, a series of analyses are conducted to understand factors affecting reliability metrics on urban arterials. Analyses …

Planning For Multiple Shopping Goals In The Marketplace, Jacob Suher, Szu-Chi Huang, Leonard Lee

Business Faculty Publications and Presentations

Four online grocery‐shopping experiments and one field study using video‐tracking technology at a grocery store document how shoppers’ motivation evolves from the beginning to the end of their shopping trips. We uncover unique motivational patterns as shoppers achieve multiple subgoals (i.e., choose multiple grocery items) to complete their trips: a monotonic decrease in motivation for shoppers with a shopping list versus a curvilinear trend (i.e., decrease then increase) in motivation for shoppers without a list. In addition, we demonstrate how to reverse the observed patterns for shoppers with a list by changing their reference points for tracking progress. The discovery …

Interrogating The Construction And Representations Of Criminalized Women In The Academic Social Work Literature: A Critical Discourse Analysis, Sandra Marie Leotti

Dissertations and Theses

In the United States today, there are 2.3 million people behind bars in jails and prisons. Mass incarceration has swept up the United States to such a degree that we are known globally for holding more people in correctional facilities than any other country in the world. Although women have always, and still do, reflect a smaller proportion of the correctional population, over the last 40 years, their rates of criminalization and imprisonment have far outpaced that of men's. Drastic increases in the criminalization of women are intimately connected to the entrenchment of social disadvantage enabled under neoliberal globalization. Neoliberal …

Enhanced Transit Corridors In Portland's Central City, Gabe Graff, Kelly Betteridge

PSU Transportation Seminars

Over the past two years, the Portland Bureau of Transportation and TriMet have joined forces to identify, design and build capital and operational treatments to help buses move more quickly and reliably through Portland’s increasingly congested Central City. Already the densest concentration of people and jobs in Oregon, Portland’s Central City is growing fast and increasing the speed and reliability of transit is key to achieving our City and region’s transportation, climate and livability goals. Working in partnership on PBOT’s Central City in Motion plan and TriMet and Metro’s Enhanced Transit Corridor program, the two agencies have identified a series …

Webinar: Aging In Place: Improving Mobility For Older Adults, Alan Kenneth Delatorre, Ivis Garcia Zambrana, Ja Young Kim

TREC Webinar Series

Aging in place can simply be defined as staying in your home as you age; aging in place concerns include mobility, social activities, safety, accessibility, and long term supports and services in one’s neighborhood and society. In order to facilitate aging in place, organizations in Salt Lake County, Utah and the City of Portland, Oregon, provided home modifications to income-qualified older adults that intended to enable aging in place. Such modifications alter individuals’ life-space mobility – a concept recently used by gerontologists and that we introduced to planners – from within one’s home to the broader community. A unique methodological …

Situational Context Of Police Use Of Deadly Force: A Comparison Of Black And White Subjects Of Fatal Police Shootings, Shana Lynn Meaney Ruess

Dissertations and Theses

Police use of deadly force is an understudied yet deeply important issue in our society. Recent years have seen a dramatic increase in public concern over use of deadly force, particularly when that force is used against people of color. Due to the relative low frequency of deadly force incidents, little is known about when such force is used, or who it is used on. Recent studies have found a racial disparity between white and black subjects of deadly force, with black subjects significantly over represented as a proportion of the population. This study further expands our understanding of police …

Closure Or Censure? Examining The Determinants Of Disclosure Of Sexual Assault Among College Students, Whitney Head-Burgess

Dissertations and Theses

Sexual assault is an ongoing problem on college campuses, with some projections indicating that one in four college women has experienced some sexual coercion or assault during her time at university. Recent national policy has strove to address the problem through legislation like the 2013 Campus Sexual Violence Elimination Act. Nonetheless, the crime remains the most underreported in the nation despite policy and law which explicitly defines what constitutes sexual assault. However, most victims of sexual assault will disclose what happened to someone else, even if they choose not to report.

This research examines sexual assault disclosure practices on a …

Effects Of Regulation Intensity On Marijuana Black Market After Legalization, Sikang Song

Dissertations and Theses

Since 2012, many states and Canada have legalized the use and sale of recreational marijuana. One of the expected benefits of the legalization is that the establishment of a legal cannabis market would eliminate the black market which has been the main form of marijuana trade for decades. Even though legal options are available for marijuana producers and consumers, the black market is still thriving in states where recreational marijuana has been legalized. The reasons behind the persistence of the marijuana black market are complex. One of the main arguments is that the legalized states have failed to establish a …

An Evaluation Of Clackamas County's Transition Center Using Propensity Score Modeling, Alicia De Jong Mckay

Dissertations and Theses

Part of the purpose of Justice Reinvestment Initiatives (JRIs) involve a focus of funds and effort toward implementing practices that increase the chances of successful reintegration of people recently released from incarceration. Similar to other jurisdictions, Oregon's JRI has taken a number of forms of reintegrative efforts. In 2016, JRI funding opened a services hub and reintegration/reentry center in a rural county. The Center offers a central location for reentry services, such as employment and housing assistance, but is not a requirement of an offender's supervision. Relying on the risk-need-responsivity framework, this program aims to reduce recidivism by mitigating barriers …

Gender And The Voir Dire Process, Tasha Ann Lane

Dissertations and Theses

The jury selection process (also known as voir dire) has been examined previously in many ways, including racial impacts. Previous research suggests the need for more examination of how and if gender impacts the voir dire process. The lack of knowledge about how gender impacts voir dire might also have implications for public respect and trust in the court system. For example, theories of procedural justice suggest that individual experiences with the legal system affect whether they view the entire legal system as being legitimate. This is important because this perception then impacts how the public interact with the system. …

Students Perception Of Open Textbooks, Karen Bjork

Library Faculty and Staff Publications and Presentations

Textbooks have long been an integral learning platform in higher education. As the rising cost of textbooks continues to burden students, many libraries have begun to facilitate the creation and publishing of open textbooks. In 2013, with the support of a Provost-backed initiative, Portland State University (PSU) Library developed an open textbook publishing program that works with faculty to create open textbooks that are designed specifically for the courses that they teach. The publishing initiative, called PDXOpen, has published 21 open textbooks. The program has saved over 2,890 PSU students over $272,000 on the cost of their books.

Leveraging Twitter And Machine Learning For Real-Time Transit Network Evaluation, Xiaoyue Cathy Liu, Qian Zuo, Shenruoyang Na, Ran Wei, Aaron Golub, Liming Wang, Jake Davis

TREC Project Briefs

With today’s profusion of open data sources and real-time feeds, transit agencies have an unparalleled opportunity to leverage large amounts of data to improve transit service. Thanks to NITC researchers, there is now an open-source tool for that.

The new Social-Transportation Analytic Toolbox (STAT) for Transit Networks, developed by researchers at the University of Utah and Portland State University, is a dynamic platform that combines Twitter, general transit feed specification (GTFS), and census transportation planning products (CTPP)—in this case, job density data—to help agencies evaluate overall system performance and identify connectivity gaps. It can also act as a decision support …

Social-Transportation Analytic Toolbox (Stat) For Transit Networks, Xiaoyue Cathy Liu, Qian Zuo, Shenruoyang Na, Ran Wei, Aaron Golub, Liming Wang, Jake Davis

TREC Final Reports

This project builds an open-source, socio-transportation analytic (STAT) toolbox for public transit system planning in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies in evaluating and enhancing the performance of public transit systems. This toolbox is novel and essential to transit agencies in two aspects. First, it enables the integration, analysis and visualization of two major, new open transportation data, social media and GTFS data, to support transit decision-making. Second, it allows transit agencies to evaluate service network efficiency and access equity of transit systems in a cohesive manner, and identify areas …

Fuse: People With Frequent Utilization Of Public Services In Clackamas County, Oregon: Potential Service Enhancements, Karen Cellarius, Marisa Zapata, Eric Einspruch, Cameron Mulder, Thuan Duong, Aliza Tuttle

Homelessness Research & Action Collaborative Publications and Presentations

The goal of this study was to answer five very specific questions about individuals with high service utilization and the systems that serve them. The data for this study comes from administrative system data, informational conversations and meetings with community partners, formal interviews with service providers, and interviews with consumers with frequent service utilization.

Limitations: The rates of mental illness, addiction and homelessness are likely to be higher than they appear in this report due to the way these characteristics were gathered or recorded in system databases. Historically marginalized populations are increasingly underrepresented in datasets.

Differentiation And Diffusion: Shifting Public Opinion Attitudes Toward Foreign Policy In North Africa, Lindsay J. Benstead

Political Science Faculty Publications and Presentations

Drawing on Arab Barometer data, this article provides the backdrop for understanding continuity and change since the Arab Spring in national-level public opinion attitudes toward economic and political foreign policy issues in North Africa, inclusive of Algeria, Egypt, Libya, Morocco, and Tunisia. The article leverages the concepts of differentiation and diffusion to understand how international affairs shape public opinion in North Africa since the Arab Spring. Three findings emerge. First, public opinion about domestic and international issues are linked in the minds of North African citizens and foreign policy issues are more important factors underlying pre- and post-Arab Spring politics …

The Impact Of Framing On Acceptance Of Cultured Meat, Christopher Bryant, Courtney Dillard

University Studies Faculty Publications and Presentations

Cultured meat can be produced from growing animal cells in-vitro rather than as part of a living animal. This technology has the potential to address several of the major ethical, environmental, and public health concerns associated with conventional meat production. However, research has highlighted some consumer uncertainty regarding the concept. Although several studies have examined the media coverage of this new food technology, research linking different frames to differences in consumer attitudes is lacking. In an experimental study, we expose U.S. adults (n = 480) to one of three different frames on cultured meat: “societal benefits,” “high tech,” and “same …

Bicycle Planning Gis Tool, Joseph Broach

TREC Final Reports

Although currently only about one percent of US trips are done by bicycle, there is significant geographic variation. Differences across communities, along with much higher cycling rates observed in other places around the world, indicates large potential bicycling demand for daily travel in the US. In response, many communities are developing and implementing bicycle master plans that include a range of bikeway infrastructure aimed at making riding more appealing, including separated paths, protected (or separated) bike lanes, striped bike lanes, bicycle boulevards, sharrows, route signage, and intersection crossing aids. Given limited resources, planners and engineers need tools to estimate the …

Characterizing The Trip Generation Profiles Of Multifamily Housing, Kelly Clifton, Kristina M. Currans

TREC Final Reports

Cities are increasingly wanting to assess the impacts new development has on all modes in the transportation system. Many communities are requiring site-level transportation impact analysis to examine travel outcomes. The historical focus on developing data and methods exclusively for the automobile, such as the Institute of Transportation Engineers (ITE) Trip Generation Handbook, has left planners with little guidance for these new challenges. This study aims to examine the limitations in the dominant approaches to understand how they may misguide the planning process for multifamily housing development. Specifically, we aim to examine the vehicle and person trip generation rates associated …

National Scan Of Bike Share Equity Programs: Approaches And Best Practices For Promoting Equity In Bike Share, Nathan Mcneil, John Macarthur, Joseph Broach, Austin Cummings, Rae-Leigh Stark, Rebecca Sanders, Adrian Witte

TREC Final Reports

As bike share systems around the United States have grown in number and size in recent years, there has been an increasing effort to ensure that those systems are accessible to all residents, particularly those who have the fewest resources or have been underserved in the past. The mobility landscape in 2019 is rapidly changing, with scooter and e-bike systems along with ride-hailing and ride-sharing companies contributing to a new and uncharted urban transportation scene. Meanwhile, bike share is still relatively new and changing quickly. In order to compete and excel in this changing landscape, particularly with regard to providing …
