Psychology Faculty Publications and Presentations

Credibility and trustworthiness are the bedrock upon which any science is built. The strength of these foundations has been increasingly questioned across the sciences as instances of research misconduct and mounting concerns over the prevalence of detrimental research practices have been identified. Consequently, the purpose of this paper is to encourage our scientific community to positively and proactively engage in efforts that foster a healthy and robust I-O psychology. We begin by advancing six defining principles that we believe reflect the values of robust science and offer criteria for evaluating proposed efforts to change scientific practices. Recognizing that the contemporary …


A Portable Toolkit For Testing Bridge Structural Integrity, Charles Riley Mar 2018

A Portable Toolkit For Testing Bridge Structural Integrity, Charles Riley

TREC Project Briefs

The goal of this study was to develop a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology (specifically iPods) to measure the dynamic structural response of a bridge subjected to harmonic forcing. Researchers leveraged principles of structural mechanics, dynamics, and vibrations, as well as a significant body of literature, to conceive a system that could complement existing visual inspection methods to support bridge condition evaluation and rating. The outcome of the project is the Rapidly Deployable Structural Evaluation Toolkit for Global Observation, or RDSETGO.

State Medicaid Fees And Access To Primary Care Physicians, Rajiv Sharma, Sarah E. Tinkler, Arnab Mitra, Sudeshna Pal, Raven Susu-Mago

Economics Faculty Publications and Presentations

Medicaid and uninsured patients are disadvantaged in access to care and are disproportionately Black and Hispanic. Using a national audit of primary care physicians, we examine the relationship between state Medicaid fees for primary care services and access for Medicaid, Medicare, uninsured, and privately insured patients who differ by race/ethnicity and sex. We found that states with higher Medicaid fees had higher probabilities of appointment offers and shorter wait times for Medicaid patients, and lower probabilities of appointment offers and longer wait times for uninsured patients. Appointment offers and wait times for Medicare and privately insured patients were unaffected by …


Defining Extreme Events: A Cross-Disciplinary Review, Lauren E. Mcphillips, Heejun Chang, Mikhail Chester, Yaella Dipletri, Erin Friedman, Nancy B. Grimm, John S. Kominoski, Timon Mcphearson, Pablo Méndez-Lázaro, Emma J. Rosi, Javad Shafiei Shiva Mar 2018

Defining Extreme Events: A Cross-Disciplinary Review, Lauren E. Mcphillips, Heejun Chang, Mikhail Chester, Yaella Dipletri, Erin Friedman, Nancy B. Grimm, John S. Kominoski, Timon Mcphearson, Pablo Méndez-Lázaro, Emma J. Rosi, Javad Shafiei Shiva

Geography Faculty Publications and Presentations

Extreme events are of interest worldwide given their potential for substantial impacts on social, ecological, and technical systems. Many climate-related extreme events are increasing in frequency and/or magnitude due to anthropogenic climate change, and there is increased potential for impacts due to the location of urbanization and the expansion of urban centers and infrastructures. Many disciplines are engaged in research and management of these events. However, a lack of coherence exists in what constitutes and defines an extreme event across these fields, which impedes our ability to holistically understand and manage these events. Here, we review 10 years of academic …


Webinar: Pooled Fund Grant 2018 - Tackling Transportation Together, Eva-Maria Muecke Feb 2018

Webinar: Pooled Fund Grant 2018 - Tackling Transportation Together, Eva-Maria Muecke

TREC Webinar Series

Information session on the Pooled Fund Research Grant

One champion identifies a problem that is common to other agencies, cities, or MPOs and then recruits other partners who are willing to collaborate and contribute financially to the project. At this point, NITC steps in and matches the funds that the partners pooled – making it possible to pursue a question that is greater in scope than any one agency or city could pursue on its own. Simple process, right? Maybe not! Yet, this process can be exciting, empowering and, most importantly, lead to the implementation of a project that produces …


College Student Rankings Of Multiple Speakers In A Public Speaking Context: A Language Attitudes Study On Japanese-Accented English With A World Englishes Perspective, John James Ahlbrecht Feb 2018

College Student Rankings Of Multiple Speakers In A Public Speaking Context: A Language Attitudes Study On Japanese-Accented English With A World Englishes Perspective, John James Ahlbrecht

Dissertations and Theses

This language attitudes study used a matched guise technique to compare participant reactions of American-accented English to Japanese-accented English. Participants (n = 40) were college educated adults living in the Portland area who completed an online survey which measured characteristics related to Status, Solidarity, and Dynamism using semantic differential Likert scales. Results showed that while Japanese-accented English received less favorable ratings on the Status and Solidarity dimensions on a statistically significant level, the small effect size may have indicated that the differences were negligible. Interpreting the results from the data through the World Englishes Kachruvian paradigm, it is argued that …

Organizational Calling And Safety: The Role Of Workload And Supervisor Support, Layla Rhiannon Mansfield Feb 2018

Organizational Calling And Safety: The Role Of Workload And Supervisor Support, Layla Rhiannon Mansfield

Dissertations and Theses

Research suggests that individuals who perceive their work as a calling (a deep passion and meaningfulness associated with a certain domain) experience a variety of positive outcomes such as occupational identification, career decidedness, and job satisfaction. Utilizing the tenets of Social Exchange Theory and the Job Demands Resources Model, I proposed that individuals with greater calling toward their occupation will report higher safety motivation and safety compliance. However, under conditions of high workload this relationship would be attenuated. Further, by the same rationale, individuals with lower calling will report lower safety outcomes, yet I proposed that this relationship is mitigated …


Recent Advances In Activity-Based Travel Demand Models For Greater Flexibility, Kihong Kim Feb 2018

Recent Advances In Activity-Based Travel Demand Models For Greater Flexibility, Kihong Kim

Dissertations and Theses

Most existing activity-based travel demand models are implemented in a tour-based microsimulation framework. Due to the significant computational and data storage benefits, the demand microsimulation allows a greater amount of flexibility in terms of demographic market segmentation, temporal scale, and spatial resolution, and thus the models can represent a wider range of travel behavior aspects associated with various policies and scenarios. This dissertation proposes three innovative methodologies, one for each of the three key dimensions, to fulfill the greater level of details toward a more mature state of activity-based travel demand models.


Road Diet V2.0 - Road Diet With Roundabouts, Michael Williams Feb 2018

Road Diet V2.0 - Road Diet With Roundabouts, Michael Williams

PSU Transportation Seminars

How can we go one step, or one lane, further than the standard road diet? Roundabouts allow a road diet to reduce the final number of lanes from three to two.

Questions arise when roundabouts are used with a road diet. What traffic volumes are supportable? Will the roundabouts fit within existing intersections? What does current guidance tell us about this approach?

Michael Williams will present his work on creating a sequel to FHWA’s Road Diet Informational Guide. This work is intended to provide a feasibility determination tool for the application of this approach to existing corridors. Data from Bird …

Goodbye To The National Endowment For The Arts?, Naomi Adiv Feb 2018

Goodbye To The National Endowment For The Arts?, Naomi Adiv

Urban Studies and Planning Faculty Publications and Presentations

In the shadow of the truly egregious policies rolled out by the Trump administration in their first year in office (anti-Muslim and anti-immigrant policies, de-staffing the State Department into paralysis, shrinking national monuments, strangling the ACA), and a general tone of chaos surrounding the office of the presidency, a standing threat remains. That is: among other cuts, freezes and gag orders, the administration has vowed to defund the National Endowment for the Arts (NEA), National Endowment for the Humanities (NEH) and the Corporation for Public Broadcasting (CPB). Here, I demonstrate how current political arguments around defunding the NEA are derived …


Financial Strain And The Work-Home Interface: A Test Of The Work-Home Resources Model From The Study For Employment Retention Of Veterans (Serve), Mackenna Laine Perry Feb 2018

Financial Strain And The Work-Home Interface: A Test Of The Work-Home Resources Model From The Study For Employment Retention Of Veterans (Serve), Mackenna Laine Perry

Dissertations and Theses

Money is consistently one of the most common and significant sources of stress in America. The American Psychological Association's annual Stress in America survey has found that money and work have been two of the top sources of "very" or "somewhat" significant stress for Americans since 2007, when the first report was released. Drawing upon the work-home resources model, this study examined the longitudinal effects of financial strain as a component of the work-home interface on a sample of 512 employed veterans from the post-9/11 era. The work-home resources model posits that contextual demands and contextual resources in one domain …


Evaluation Of Route Changes Utilizing High-Resolution Gps Bus Transit Data, Travis Bradley Glick Feb 2018

Evaluation Of Route Changes Utilizing High-Resolution Gps Bus Transit Data, Travis Bradley Glick

PSU Transportation Seminars

Congestion and travel delay on urban roadways can influence operating costs and service attractiveness. This research uses high resolution bus data to examine sources of delay on urban arterials. A set of tools was created to help visualize trends in bus behavior and movement; this allowed larger traffic trends to be visualized along urban corridors and urban streets. By using buses as probes and examining aggregated bus behavior, contoured speed plots can be used to understand the behavior of roadways outside the zone of influence of bus stops. Speed plots can be utilized to discover trends and travel patterns with …


Valuing Bicycle Infrastructure In Portland, Oregon, Wei Shi Feb 2018

Valuing Bicycle Infrastructure In Portland, Oregon, Wei Shi

PSU Transportation Seminars

Investments into active transportation infrastructure are often promoted as a strategy for sustainable transportation, better public health, environmental quality, and economic development. Although empirical evidence generally points toward positive property value impacts of off-street greenways and trails, few focus on whether households might have different willingness-to-pay for different types and levels of bicycle infrastructure. This paper aims to fill research gaps in understanding consumer preferences for different types of bicycle facilities by examining property value impacts of four bicycle facility types: on-street advanced bike facilities and bike lanes; and off-street regional multi-use paths and local multi-use paths. Using Portland, Oregon …

Benefit Relevant Indicators: Ecosystem Services Measures That Link Ecological And Social Outcomes, Lydia Olander, Robert J. Johnston, Heather Tallis, James S. Kagan, Lynn A. Maguire, Stephen Polasky, Dean Urban, James Boyd, Lisa Wainger, Margaret A. Palmer

Institute for Natural Resources Publications

There is a growing movement in government, environmental non-governmental organizations and the private sector to include ecosystem services in decision making. Adding ecosystem services into assessments implies measuring how much a change in ecological conditions affects people, social benefit, or value to society. Despite consensus around the general merit of accounting for ecosystem services, systematic guidance on what to measure and how is lacking. Current ecosystem services assessments often resort to biophysical proxies (e.g., area of wetland in a floodplain) or even disregard services that seem difficult to measure. Valuation, an important tool for assessing trade-offs and comparing outcomes, is …


Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub Feb 2018

Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

This study investigates the impacts of positive and negative externalities of highways and light rail on commercial property values in Phoenix, Arizona. We hypothesize that the positive externality (i.e., accessibility) of highway and light rail accrues at exits and stations, whereas nodes and links of highways and light rail emanate negative effects. Positive and negative effects decay with increasing distance and are captured by multiple distance bands. Hypotheses are tested using a spatial error regression model. Results show that commercial property values are positively and significantly associated with the accessibility benefits of transport nodes. The distance-band coefficients form a typical …

Oregon City School District Enrollment Forecasts 2018-19 To 2027-28, Portland State University. Population Research Center, Charles Rynerson, Scott Stewart

School District Enrollment Forecast Reports

This report presents a range of three scenarios of district‐wide enrollment forecasts by grade level for the Oregon City School District (OCSD) for the 10 year period between 2018‐19 and 2027‐28. Each enrollment forecast scenario is related to population forecasts that incorporate different assumptions about growth within the District, with the primary differences being the contribution of net migration to the District’s population and age distribution. Individual school forecasts consistent with the middle range scenario are also presented for the 10 year period.


Shifted Baselines Reduce Willingness To Pay For Conservation, Loren Mcclenachan, Ryunosuke Matsuura, Payal Shah, Sahan T.M. Dissanayake Feb 2018

Shifted Baselines Reduce Willingness To Pay For Conservation, Loren Mcclenachan, Ryunosuke Matsuura, Payal Shah, Sahan T.M. Dissanayake

Economics Faculty Publications and Presentations

A loss of memory of past environmental degradation has resulted in shifted baselines, which may result in conservation and restoration goals that are less ambitious than if stakeholders had a full knowledge of ecosystem potential. However, the link between perception of baseline states and support for conservation planning has not been tested empirically. Here, we investigate how perceptions of change in coral reef ecosystems affect stakeholders' willingness to pay (WTP) for the establishment of protected areas. Coral reefs are experiencing rapid, global change that is observable by the public, and therefore provide an ideal ecosystem to test links between beliefs …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Academic health centers (AHCs) are under increased pressure to demonstrate the effectiveness of their community-engaged activities, but there are no common metrics for evaluating community engagement in AHCs. Eight AHCs piloted the Institutional Community Engagement Self-Assessment (ICESA), a two-phase project to assess community-engagement efforts. The first phase uses a framework developed by the University of Rochester Medical Center, which utilizes structure, process, and outcome criteria to map CE activities. The second phase uses the Community-Campus Partnerships for Health (CCPH) Self-Assessment to identify institutional resources for community engagement, and potential gaps, to inform community engagement goal-setting. The authors conducted a structured, …

Fisheries’ Property Regimes And Environmental Outcomes: A Realist Synthesis Review, Rebecca J. Mclain, Steven Lawry, Maria Ojanen Feb 2018

Fisheries’ Property Regimes And Environmental Outcomes: A Realist Synthesis Review, Rebecca J. Mclain, Steven Lawry, Maria Ojanen

Geography Faculty Publications and Presentations

Our paper describes the application of a realist approach to synthesizing evidence from 31 articles examining the environmental outcomes of marine protected areas governed under different types of property regimes. The development of resource tenure interventions that promote sustainable management practices has been challenged by the difficulties of determining how contextual factors affect environmental outcomes given the complexity of socio-ecological systems. Realist synthesis is a promising evidence review technique for identifying the mechanisms that influence policy intervention outcomes in complex systems. Through a combination of inductive and deductive analysis of the links between context, mechanisms, and outcomes, realist synthesis can …


Student Motivation Profiles As A Diagnostic Tool To Help Teachers Provide Targeted Support, Cailin Tricia Currie Jan 2018

Student Motivation Profiles As A Diagnostic Tool To Help Teachers Provide Targeted Support, Cailin Tricia Currie

Dissertations and Theses

Research has demonstrated that academic engagement is an important resource for students, promoting their learning and achievement. Less well documented is the possibility that students' classroom engagement may also be a valuable resource for their teachers, capable of influencing how teachers treat their students over time. The current study sought to examine the relationship between student motivation and teacher behavior to better understand how teachers perceive and respond to their students' classroom motivation and whether these motivational states contain diagnostic information about the types of supports students may need in order to be engaged, enthusiastic learners. The observable manifestations of …


Modeling The Co-Production Of Public Sector Innovation: Strategic Dimensions Of Organizational Innovation Within The Public Maritime Ports Of The Pacific Northwest, Christopher R. Davis Jan 2018

Modeling The Co-Production Of Public Sector Innovation: Strategic Dimensions Of Organizational Innovation Within The Public Maritime Ports Of The Pacific Northwest, Christopher R. Davis

Dissertations and Theses

Innovation is vital to employing resources in times when the complexity and the demand for public goods and services strain organizational capacities. While innovation in the private sector is the subject of intense academic interest, the study of this phenomenon in the public sector pales in comparison. This is troubling because innovation is an important tool for overcoming resource limitations that plague the public sector. This dissertation's unique contribution to the field is the creation and empirical validation of a model that explains and predicts the co-production of public sector innovation. The model explains the causal mechanism of innovation and …


Defining Place: A Review Of How Place Type Is Measured And Constructed, Kelly Rodgers Jan 2018

Defining Place: A Review Of How Place Type Is Measured And Constructed, Kelly Rodgers

PSU Transportation Seminars

Part of the Student Presentations from TRB

Researchers have been parsing which components of the built environment contribute to outcomes of interest and to what degree, particularly the effects on vehicle use and walking. Increasingly, researchers and practitioners recognize that the type of neighborhood may affect individual travel behaviors. These bundle of various land use and transportation system characteristics can be constructed as different neighborhood or place types. But not all place types are constructed with the same use, purpose, or methods. This presentation will review three classifications of place typologies to better understand their purpose and appropriate application as …


Holocene Dynamics Of Temperate Rainforests In West-Central Patagonia, Virginia Iglesias, Simon G. Haberle, Andrés Holz, Cathy Whitlock Jan 2018

Holocene Dynamics Of Temperate Rainforests In West-Central Patagonia, Virginia Iglesias, Simon G. Haberle, Andrés Holz, Cathy Whitlock

Geography Faculty Publications and Presentations

Analyses of long-term ecosystem dynamics offer insights into the conditions that have led to stability vs. rapid change in the past and the importance of disturbance in regulating community composition. In this study, we (1) used lithology, pollen, and charcoal data from Mallín Casanova (47°S) to reconstruct the wetland, vegetation, and fire history of west-central Patagonia; and (2) compared the records with independent paleoenvironmental and archeological information to assess the effects of past climate and human activity on ecosystem dynamics. Pollen data indicate that Nothofagus-Pilgerodendronforests were established by 9,000 cal yr BP. Although the biodiversity of the understory increased …


Density Differences: Exploring Built Environment Relationships With Walking Between And Within Metropolitan Areas, Jamie Orrego Jan 2018

Density Differences: Exploring Built Environment Relationships With Walking Between And Within Metropolitan Areas, Jamie Orrego

PSU Transportation Seminars

Part of the Student Presentations from TRB

To explore the relationships between measures of density and walking within and between urban areas, we present an analysis of the travel survey data from six different cities from the US and Santiago, Chile. The analysis of aggregate and disaggregate pedestrian trips presented here examine the potential consistency of relationships between walking and density within and across different regions, with a specific focus on population density. Our findings illustrate a relationship between population density and walk mode shares that is roughly linear and of nearly equal magnitude across US regions in densities below …
