Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang Jan 2019

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are …


Community-Engaged Teaching: Lessons From A Participatory History Project, Amie Thurber, Sarah V. Suiter Jan 2019

Community-Engaged Teaching: Lessons From A Participatory History Project, Amie Thurber, Sarah V. Suiter

School of Social Work Faculty Publications and Presentations

How can we create opportunities for students to gain experience in community-engaged scholarship that truly benefits the community given the constraints of the academic calendar, students’ varied capacity to develop reciprocal and responsive community relationships, and the tendency for community-engaged research to instrumentalize community partners in service to academic deliverables? This paper explores one attempt to meet this challenge: an experimental graduate course in community development that linked course content to a participatory history project. Designed as a Scholarship of Teaching and Learning (SoTL) study, instructors studied the instructional process as well as outcomes for students and community partners. We …

Stigmatization And Mental Illness: The Communication Of Social Identity Prototypes Through Diagnosis Labels, Justin Samuel Leverett Jan 2019

Stigmatization And Mental Illness: The Communication Of Social Identity Prototypes Through Diagnosis Labels, Justin Samuel Leverett

Dissertations and Theses

This study tested whether participants exposed to a vignette describing an individual experiencing symptoms of depression, which included only the specific diagnosis label of "depression," would report significantly less stigmatized responses than participants exposed to an otherwise identical vignette which included only the non-specific diagnosis label "mental illness." The study is grounded in past research on stigmatization of mental illness and is informed by three theoretical frameworks, the social identity perspective, attribution theory, and labeling theory. Participants were randomly assigned to read one of the two alternate vignettes, then respond to a series of measures testing desire for social distance, …


Frequency Of Social Contact In-Person Vs. On Facebook: An Examination Of Associations With Psychiatric Symptoms In Military Veterans, Alan R. Teo, Benjamin K. Chan, Somnath Saha, Christina Nicolaidis Jan 2019

Frequency Of Social Contact In-Person Vs. On Facebook: An Examination Of Associations With Psychiatric Symptoms In Military Veterans, Alan R. Teo, Benjamin K. Chan, Somnath Saha, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

Introduction: Social isolation is closely associated with negative mental health outcomes. Social media platforms may expand opportunities for social contact, but whether online interactions are as effective as face-to-face, or in-person, interactions at protecting against the negative effects of social isolation is unclear.

Methods: Participants consisted of U.S. military veterans who served since September 2001 and used Facebook (n = 587). Our independent variables were frequency of social contact occurring in-person and on Facebook. Dependent variables were probable psychiatric disorders and suicidality, measured using several validated screening tools. The independent effect of each form of social contact was assessed using …


Recognizing And Addressing Risk Ambiguity In Sea Level Rise Adaptation Planning: A Case Study Of Miami-Dade County, Florida, Mary Ann Rozance Jan 2019

Recognizing And Addressing Risk Ambiguity In Sea Level Rise Adaptation Planning: A Case Study Of Miami-Dade County, Florida, Mary Ann Rozance

Dissertations and Theses

As coastal cities around the world identify and implement adaptations to sea level rise, they are faced with competing interests around what should be done and how to prioritize actions. Often, environmental problems--like confronting the challenge of sea level rise--are posed as requiring expert driven, technical solutions to identify and mitigate risks across the landscape. This framing, however, ignores the way in which diverse knowledge can help inform long-term planning horizons that address complex ways that sea level rise affects communities. The failure to integrate diverse knowledge into sea level rise adaptation can result in barriers to implementation and outcomes …


Rapid Serial Visual Presentation Interacts With Ambiguity During Sentence Comprehension, Sarah Key-Delyria, Todd Bodner, Lori J. P. Altmann Jan 2019

Rapid Serial Visual Presentation Interacts With Ambiguity During Sentence Comprehension, Sarah Key-Delyria, Todd Bodner, Lori J. P. Altmann

Psychology Faculty Publications and Presentations

Conventional opinion about using Rapid Serial Visual Presentation (RSVP) for examining sentence comprehension maintains that RSVP taxes working memory (WM), which probably affects sentence processing. However, most RSVP studies only infer the involvement of WM. Other cognitive resources, such as cognitive control or vocabulary may also impact sentence comprehension and interact with RSVP. Further, sentence ambiguity is predicted to interact with RSVP and cognitive resources to impact sentence comprehension. To test these relationships, participants read ambiguous and unambiguous sentences using RSVP and Whole-Sentence presentation, followed by comprehension questions that were targeted to the ambiguous region of the sentences. Presentation type …


Evaluating The Impact And Distribution Of Stormwater Green Infrastructure On Watershed Outflow, Benjamin Fahy Jan 2019

Evaluating The Impact And Distribution Of Stormwater Green Infrastructure On Watershed Outflow, Benjamin Fahy

Dissertations and Theses

Green Stormwater Infrastructure (GSI) has become a popular method for flood mitigation as it can prevent runoff from entering streams during heavy precipitation. In this study, a recently developed neighborhood in Gresham, Oregon hosts a comparison of various GSI projects on runoff dynamics. The study site includes dispersed GSI (rain gardens, retention chambers, green streets) and centralized GSI (bioswales, detention ponds, detention pipes). For the 2017-2018 water year, hourly rainfall and observed discharge data is used to calibrate the EPA's Stormwater Management Model to simulate rainfall-runoff dynamics, achieving a Nash-Sutcliffe efficiency of 0.75 and Probability Bias statistic of 3.3%.

How Much Do Emotional, Behavioral, And Cognitive Factors Actually Impact College Student Attitudes Towards English Language Learning? A Quantitative And Qualitative Study, Xin Zuo, Regina D. Weaver, Julia Macrae, Limin Wang Jan 2019

How Much Do Emotional, Behavioral, And Cognitive Factors Actually Impact College Student Attitudes Towards English Language Learning? A Quantitative And Qualitative Study, Xin Zuo, Regina D. Weaver, Julia Macrae, Limin Wang

Intensive English Language Program Faculty Publications and Presentations

Researchers have proposed many multidimensional frameworks to identify significant and potential factors, e.g., educational background, positive feelings and career aspirations, that impact English learning attitude in second language acquisition. Yet, there is still very little research to graphically describe the interactions between these factors and how these factors directly or indirectly impact learning attitude. To this end, a questionnaire survey was conducted in Changchun University of Technology. Statistical measures and Bayesian network analysis were introduced to quantitatively and qualitatively analyze the collected data. Furthermore, the significant attitudinal differences between students majoring in the Liberal Arts or Sciences were investigated for …

Building The Case For Culturally Specific P-3 Strategies In Oregon: Listening To Voices From The Field, Callie H. Lambarth, Amanda Cross-Hemmer, Lorelei Mitchell, Beth L. Green, Kate Normand

Early Childhood

Oregon’s early learning and K-12 systems require transformative changes to address racial disparities in school readiness and success. Prenatal-through-Grade-3 (P-3) initiatives are an innovative way to align, strengthen and expand supports for this goal.

Culturally specific organizations (CSOs) are uniquely poised and expertly prepared to meet the needs of communities of color while helping Oregon achieve its goals for reducing disparities in kinder­garten readiness and other educational outcomes.

The proposed Early Childhood Equity Fund, which is included in the governor’s recommended 2019 budget, would move Oregon closer to eliminating the opportunity gap in kindergarten readiness and school success by investing …

Social Equity In Transit Service: Toward Social And Environmental Justice In Transportation, Torrey Lyons Jan 2019

Social Equity In Transit Service: Toward Social And Environmental Justice In Transportation, Torrey Lyons

TREC Theses and Dissertations

This dissertation explores social equity as it applies to public transportation. Transit has long been considered a tool to alleviate inequity by limiting the effects of spatial mismatch and providing access to opportunity to disadvantaged populations. This theory, however, has not been adequately proven empirically. The first chapter of this dissertation tests the theory that spatial mismatch is moderated by quality transit service. We do this by taking a cross section of the largest urban areas in the United States and applying structural equation modeling to identify relationships between exogenous and endogenous factors. We find that higher quality transit service …

Making The Connection: Municipal Broadband Meets A Need In The Portland Metropolitan Area, Eavan Moore

Metroscape

Internet access has become critical to participating in modern American society, yet the private market is no closer to serving low-income and rural Americans.

In May 2018, the City of Hillsboro announced it would go ahead with a publicly owned and operated, affordable, gigabit-speed Internet service for the entire city. Multnomah County Commissioners voted for a feasibility study of their own in June. The Port of Ridgefield, Washington, has big hopes for its own fiber optic project. Meanwhile, the city of Sandy, Oregon, has been running its own municipal broadband service for the last six years.

What’s driving this wave? …

Plea Bargaining: The Influence Of Counsel, Kelsey S. Henderson, Lora M. Levett Jan 2019

Plea Bargaining: The Influence Of Counsel, Kelsey S. Henderson, Lora M. Levett

Criminology and Criminal Justice Faculty Publications and Presentations

For the criminal defendant, his attorney acts as his loyal and zealous advocate before the court (American Bar Association, 2015), and due process protections of the U.S. adversarial system have afforded this relationship special privilege. In this chapter, we explore the influence and role of the attorney in plea decision making. We first explore the legal context of the attorney’s role in plea bargaining, reviewing several cases that address a defendant’s right to effective assistance of counsel. We then review the shadow of trial theory and other theoretical perspectives as they relate to the attorney’s role in the plea-bargaining process, …

Harnessing Sustainable Motivation: A Grounded Theory Exploration Of Public Service Motivation In Local Governments Of The State Of Oregon, United States, Sajjad Haider, Guoxian Bao, Gary Larsen, Muhammad Umar Draz

Public Administration Faculty Publications and Presentations

Employee motivation has always been a matter of concern for both public and private sector organizations. Since the industrial revolution in the late 18th century, organizations have struggled to foster workforce motivation and morale to enhance productivity. While a plethora of literature focuses on private sector motivation research, public sector organizations receive only modest scholarly attention. However, a new concept has emerged in public management literature during the late 1980s and 1990s, later known as public service motivation (PSM). The debate about PSM is premised on the notion that the motivation of public sector employees is quite different from their …

Communication Faculty Publications and Presentations

Communication interventions can make valuable contributions to the democratic development of citizens. This article reports on a nongovernmental organization’s (NGO’s) effort to leverage a television rap news program in Uganda to strengthen viewers’ democratic norms. Two different approaches addressing government failures and malfeasance are tested with an experiment conducted in six villages outside of Kampala. Results indicate that soft news segments can influence viewers’ perceived democratic norms and shape downstream behaviors as well. Beneficial effects were strongest when participants were exposed to stories that featured relatable citizens demonstrating desirable democratic attitudes and behaviors. Treatment effects were most pronounced among less …

Environmental Science and Management Faculty Publications and Presentations

The annual trade in exotic vertebrates as pets is a multi-billion- dollar global business. Thousands of species, and tens of millions of individual animals, are shipped both internationally and within countries to satisfy this demand. Most research on the exotic pet trade has focused on its contribution to native biodiversity loss and disease spread. Here, we synthesize information across taxa and research disciplines to document the exotic pet trade’s contribution to vertebrate biological invasions. We show recent and substantial worldwide growth in the number of non-native animal populations introduced via this invasion pathway, which demonstrates a strong potential to increase …


The Use Of Generic Avoidant Coping Scales For Psychosocial Adaptation To Chronic Illness And Disability: A Systematic Review, Hanoch Livneh Jan 2019

The Use Of Generic Avoidant Coping Scales For Psychosocial Adaptation To Chronic Illness And Disability: A Systematic Review, Hanoch Livneh

Counselor Education Faculty Publications and Presentations

This systematic review examined the validity of generic coping-with-stress measures in the relationships between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Major data bases were searched for studies on the association between avoidance-type coping and psychosocial adaptation to chronic illness and disability. Findings indicated that reliance upon avoidance-type coping is linked to reports of poorer psychosocial adaptation. The veracity of these findings must be treated cautiously owing to conceptual, structural, psychometric, and other issues. Users of generic coping measures should consider these concerns prior to empirically investigating the link between generic avoidance-type coping measures and psychosocial adaptation …

Indigenous Housing In Metro-Areas: Leveraging Federal Block Grants For Urban Housing, Homelessness Research & Action Collaborative, Portland State University

Homelessness Research & Action Collaborative Publications and Presentations

The Native American Housing Assistance and Self Determination Act of 1996 (NAHASDA) established a single flexible federal block grant for tribes and Tribally Designated Housing Entity to provide housing assistance to their tribal members. This shift recognized Native rights of tribal self-determination and self-governance, and it reorganized the mechanism by which tribes received compensation for land cessions. The U.S. Department of Housing and Urban Development currently administers the Indian Housing Block Grant (IHBG) annually, with funds typically prioritized to housing on reservation or tribal lands. In Oregon, a majority of funds go to the ongoing operation and maintenance of 1937 …
