Community Transportation Academy: Course Curriculum And Implementation Handbook, Nathan Mcneil, Keith Bartholomew

TREC Final Reports

A Community Transportation Academy (CTA) is a course that harnesses the knowledge, technical expertise and passions of practicing transportation professionals in a city to immerse a cohort of interested and dedicated community members in transportation issues over a two to three month curriculum.

The CTA curriculum was developed by drawing from the Portland Traffic and Transportation (PTT or Portland CTA) course, along with the Wasatch Transportation Academy (WTA or Wasatch CTA, which was inspired by the Portland course). Planning academy courses in cities around the country are also good models to look to for how to structure and operate such …

The National Bioengineered Food Disclosure Standard Of 2016: Intersection Of Technology And Public Understanding Of Science In The United States, Brianne Suldovsky, William K. Hallman

Communication Faculty Publications and Presentations

Genetically modified (GM) foods have been commercially available in the US for more than two decades, yet Americans know very little about them. With the implementation of the National Bioengineered Food Disclosure Standard of 2016, food manufacturers will be required to disclose the presence of GM ingredients in their food products. How food manufacturers communicate with consumers about GM ingredients may have consequences for public understanding of GM technology. In Study 1, we explore how food manufacturers characterize GM ingredients within their food products on SmartLabel, a digital disclosure website established by the Grocery Manufacturers Association. In Study 2, we …

A Systematic Comparison Of In-Person And Video-Based Online Interviewing, Bojana Lobe, David L. Morgan, Kim Hoffman

Sociology Faculty Publications and Presentations

Due to the increasing popularity of online qualitative interviewing methods, we provide a systematically organized evaluation of their advantages and disadvantages in comparison to traditional in-person interviews. In particular, we describe how individual interviews, dyadic interviews, and focus groups operate in both face-to-face and videoconferencing modes. This produces five different areas for comparison: logistics and budget, ethics, recruitment, research design, and interviewing and moderating. We conclude each section with set of recommendations, and conclude with directions for future research in online interviewing.

The Role Of Interdependencies In Blockchain Adoption: The Case Of Maritime Trade, Melissa M. Appleyard, Kristi Yuthas

Business Faculty Publications and Presentations

Despite its many potential economic and organisational benefits, enterprise blockchain (distributed ledger) technology has still not been widely adopted. From the viewpoint of the participants, the deployment of a blockchain that links collaborating enterprises requires value creation that will exceed investment, including investment in operational and strategic change. The theory behind and practice of cross-enterprise open innovation can inform blockchain adoption. Blockchain implementation requires and creates interdependencies across collaborators, both among enterprise consortium partners and with stakeholders in the broader ecosystem. Distinguished from arm’s-length forms of collaboration, interdependencies occur when organisations intentionally collaborate to become reliant upon one another. In …

A New Classification Network For Diagnosing Alzheimer’S Disease In Class-Imbalance Mri Datasets, Ziyang Chen, Zhuowei Wang, Meng Zhao, Qin Zhao, Xuehu Liang, Jiajian Li, Xiaoyu Song

Electrical and Computer Engineering Faculty Publications and Presentations

Automatic identification of Alzheimer’s Disease (AD) through magnetic resonance imaging (MRI) data can eectively assist to doctors diagnose and treat Alzheimer’s. Current methods improve the accuracy of AD recognition, but they are insufficient to address the challenge of small interclass and large intraclass dierences. Some studies attempt to embed patch-level structure in neural networks which enhance pathologic details, but the enormous size and time complexity render these methods unfavorable. Furthermore, several self-attention mechanisms fail to provide contextual information to represent discriminative regions, which limits the performance of these classifiers. In addition, the current loss function is adversely aected by outliers …

Can Fiscal Recentralization Strengthen Local Government? The Case Of Thailand, Bruce Gilley, Sirisak Laochankham

Political Science Faculty Publications and Presentations

Thailand in 2018 became the latest developing country to impose mandatory rules on its fiscal policy that included a national limit on the accumulation of public debt and direct control of local government budgets. Such fiscal recentralization is generally assumed in the literature on multi-level finance to weaken local economic, fiscal, and policy conditions. Yet a newer emphasis in this literature asserts the potential value of central governments in steering and constraining local governments through public finance. Such central steering may strengthen rather than weaken local governments via fiscal, economic, and policy conditions. In this paper, we use the emergent …

Shaheen Bagh: Muslim Women Contesting And Theorizing Citizenship And Belonging During Covid-19, Priya Kapoor

International & Global Studies Faculty Publications and Presentations

This paper documents an important slice of global South COVID-19 history, of primarily Muslim women's protests against the Indian Government and Legislature for taking away their constitutional rights as citizens. The Shaheen Bagh mobilization has already become an important disruption in contemporary Indian history stirring public intellectuals to probe the question: “who is a citizen of India?” in their scholarship and public-community work. By virtue of the disruption the event has caused in the enactment of the citizenship law, including other biometric directives, CAA-NRC-NPR, it has ceased to be regarded a minority or marginalized occurrence. This paper examines the writings …

Do Parents Matter For Student Loan Repayment After Graduation?, Byeongdon Oh

Sociology Faculty Publications and Presentations

Previous studies suggest that a college degree is the great equalizer leveling the playing field. However, the rapidly growing educational debt of college graduates might restrict their life chances throughout adulthood, particularly for those raised in socioeconomically disadvantaged families. This study uses data from the National Survey of College Graduates to examine whether parents’ socioeconomic status is related to their children’s student loan repayment after graduation. Holding the amount borrowed for completing higher education constant, college graduates with less educated parents hold a larger amount of educational debt in adulthood compared with their counterparts with more educated parents. The association …

Equity And Exclusion Issues In Cashless Fare Payment Systems For Public Transportation, Aaron Golub, Anne Brown, Candace Brakewood, John Macarthur, Sangwan Lee, Abubakr Ziedan

Urban Studies and Planning Faculty Publications and Presentations

Many transit agencies in the United States plan to automate their fare collection and limit–or even eliminate–the use of cash fares, with the goals of expediting boarding, collecting data, and lowering costs. Yet about 10% of US adults lack a bank account or credit card, and many rely on restrictive cellphone data plans or do not have access to the internet or a smartphone. These riders will find it difficult to access transit in the future. This paper examines transit users’ experiences with fare technologies using a survey of riders in three cities. Our analysis reveals which riders are most …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background:The adverse impact of COVID-19 on marginalized and under-resourced communities of color has highlighted the need for accurate, comprehensive race and ethnicity data. However, a significant technical challenge related to integrating race and ethnicity data in large, consolidated databases is the lack of consistency in how data about race and ethnicity are collected and structured by health care organizations.

Objective:This study aims to evaluate and describe variations in how health care systems collect and report information about the race and ethnicity of their patients and to assess how well these data are integrated when aggregated into a large clinical database. …

Evaluating The Effect Of San Francisco’S Paid Parental Leave Ordinance On Birth Outcomesf, Deborah Karasek, Sarah Raifman, Rita Hamad, William H. Dow, Julia M. Goodman

OHSU-PSU School of Public Health Faculty Publications and Presentations

Since 2017, San Francisco’s Paid Parental Leave Ordinance (PPLO) has allowed parents who work for private-sector employers to take 6 weeks of fully paid postnatal parental leave. Previous studies have linked paid parental leave with health improvements for birthing people and babies, although evidence for birth outcomes is limited. We hypothesized that the PPLO may have improved birth outcomes via reduced stress during pregnancy due to anticipation of increased financial security and postnatal leave. We used linked California birth certificate and hospital discharge records from January 2013 to December 2018 (n = 1,420,781). We used quasi-experimental difference-in-difference (DD) models to …

Adding Chinese Herbal Medicine To Routine Care Is Associated With A Lower Risk Of Rheumatoid Arthritis Among Patients With Asthma: A Population-Based Retrospective Cohort Study, Wei-Chiao Chang, Hanoch Livneh, Wei-Jen Chen, Chang-Cheng Hsieh, Yu-Han Wang, Ming-Chi Lu, How-Ran Guo, Tzung-Yi Tsai

Counselor Education Faculty Publications and Presentations

Objective: Due to the shared pathogenesis of asthma and rheumatoid arthritis (RA), patients with asthma were found to have a higher risk of RA. While the benefits and safety of Chinese herbal medicine (CHM) for asthma have been reported, the scientific evidence regarding its effect on RA is limited. This longitudinal cohort study aimed to determine the relation between CHM use and RA risk in patients with asthma.

Methods: Using the nationwide claims data, we enrolled 33,963 patients 20–80 years of age who were newly diagnosed with asthma and simultaneously free of RA between 2000 and 2007. From this sample, …

E-Cigarette Addiction And Harm Perception: Does Initiation Flavor Choice Matter?, Man Hung, Andrew Spencer, Eric S. Hon, Val Joseph Cheever, Frank W. Licari, Ryan Moffat, Clarissa Goh, Ben Raymond, Martin S. Lipsky

Institute on Aging Publications

Introduction

The 21st century was marked by a dramatic increase in adolescent e-cigarette use in the United States (US). The popularity of non-traditional flavor types, including fruit and pastry, is thought to contribute toward growing product use nationally, leading to a variety of federal and state regulations limiting the use of non-traditional flavors in the US. The relationship between flavor type and increased adolescent use suggests a possible link between flavor use and addiction and harm perception. This study assessed if the flavor type used when initiating e-cigarette use predicted addiction and harm perceptions.

Methods

The study utilized data from …

Seqcode: A Nomenclatural Code For Prokaryotes Described From Sequence Data, Brian P. Hedlund, Maria Chuvochina, Philip Hugenholtz, Konstantinos T. Konstantinidis, Alison E. Murray, Marike Palmer, Donovan H. Parks, Alexander J. Probst, Anna-Louise Reysenbach, Multiple Additional Authors

Biology Faculty Publications and Presentations

Most prokaryotes are not available as pure cultures and therefore ineligible for naming under the rules and recommendations of the International Code of Nomenclature of Prokaryotes (ICNP). Here we summarize the development of the SeqCode, a code of nomenclature under which genome sequences serve as nomenclatural types. This code enables valid publication of names of prokaryotes based upon isolate genome, metagenome-assembled genome or single-amplified genome sequences. Otherwise, it is similar to the ICNP with regard to the formation of names and rules of priority. It operates through the SeqCode Registry (https://seqco.de/), a registration portal through which names and …

“The Broker Of Reality”: A Scoping Review Of Moral Reconation Therapy, Sam Harrell, Constance Johnson, Chandler Boys, Brianna Suslovic, Ben Anderson-Nathe, Kassandra Botts

School of Social Work Faculty Publications and Presentations

Purpose: This scoping review aims to identify the evidence-based literature supporting Moral Reconation Therapy (MRT), a cognitive-behavioral treatment program created in 1987 and implemented in correctional-treatment settings across the US. Social work students and practitioners are among MRT’s facilitators.

Method: We analyze the reliability and validity of the most recent meta-analysis of MRT, covering studies published between 1988 and 2010. We then identify 669 potential publications on MRT published between 2011 and 2021.

Results: Our search across Google Scholar and eleven academic databases yielded zero peer-reviewed studies on MRT’s effectiveness or outcomes.

Identifying Population Hollowing Out Regions And Their Dynamic Characteristics Across Central China, Bin Guo, Yi Bian, Lin Pei, Xiaowei Zhu, Dingming Zhang, Wencai Zhang, Xianan Guo, Qiuji Chen

Mechanical and Materials Engineering Faculty Publications and Presentations

Continuous urbanization and industrialization lead to plenty of rural residents migrating to cities for a living, which seriously accelerated the population hollowing issues. This generated series of social issues, including residential estate idle and numerous vigorous laborers migrating from undeveloped rural areas to wealthy cities and towns. Quantitatively determining the population hollowing characteristic is the priority task of realizing rural revitalization. However, the traditional field investigation methods have obvious deficiencies in describing socio-economic phenomena, especially population hollowing, due to weak efficiency and low accuracy. Here, this paper conceives a novel scheme for representing population hollowing levels and exploring the spatiotemporal …

Dress And Identity: Using Sartorial Artifacts To Explore Identity At Fort Vancouver, Dana Marie Sukau

Dissertations and Theses

How an individual dresses is an outward expression of their identity, which impacts how they are perceived by others and their daily interactions. By modifying their dress an individual can better adapt to changing social situations. The Pacific Northwest fur trade brought people of varied backgrounds together at frontier forts like the Hudson's Bay Company owned Fort Vancouver, located in modern day Vancouver, Washington. In these areas of culture contact social relations were frequently changing, and by adapting their dress an individual could put on various "social skins" differentially influencing their daily interactions (Loren 2001). Through the perspective of practice …

System Design For The Quantification Of Microbial Motility In Extreme Environments, Megan Marie Dubay

Dissertations and Theses

Motility of microorganisms is understudied but provides useful insights into their behavior. Organisms' ability to move autonomously changes how they interact with their environment--finding nutrients, interacting with other organisms, and avoiding unfavorable conditions. Understanding motility features can also be used to identify specific species, such as the identification of Vibrio cholerae in human samples. Motility might also be used as evidence of life existing in even the most extreme environments on Earth, and possibly beyond. Specialized microscopy systems can be required to examine the motility of microorganisms due to the nature of the environments to which the instruments are exposed. …

Multimodal Imaging Of Structural Concrete Using Image Fusion And Deep Learning, Sina Mehdinia

Dissertations and Theses

Concrete structures may be exposed to a variety of loads and environments during their service life. Non-destructive testing (NDT) techniques can be helpful in evaluating the condition of a structure. Imaging provides a visual representation of the interior of concrete and its condition non-destructively. Ground penetrating radar (GPR) and ultrasonic echo array (UEA) using electromagnetic and stress waves, respectively, provide the data that can be used to reconstruct an image. In this PhD dissertation, image reconstruction and fusion algorithms, simulation, and a deep learning model were investigated with the goal to lay the foundation for enhanced imaging applications for concrete. …

Model.Disclose(): Examination Of Obsessive-Compulsive Disorder Disclosure At Work, Timothy Allen Carsey

Dissertations and Theses

Research focused on Identity Management (IDM) in the workplace has explored the experiences of people with many different stigmatized identities (e.g., sexual orientation, gender identity, race/ethnicity, religiosity); however, research has only recently begun to explore IDM of mental illness in the workplace. One such identity, Obsessive-Compulsive Disorder (OCD), has remained particularly unexplored. Individuals with mental illnesses, such as OCD, experience unique consequences with their concealment and disclosure process. Specifically, OCD has both cognitive and behavioral components, and, the behavioral component of OCD can demonstrate to coworkers visible actions that are seen as "not normal" or "awkward," potentially unintentionally signaling the …

Curating Conflict: The Material Record Of The Philippine-American War At The Oregon Historical Society, Silvie M. Andrews

Dissertations and Theses

1898 marked the beginning of U.S. colonialism in the Philippines and the formation of the Oregon Historical Society (OHS), an organization that would later inherit a vast collection of Philippine and Spanish war booty from the defunct Battleship Oregon Museum. This thesis will explore the meaning of this war booty by recreating the context around its collection, accession, interpretation, and later descent into obscurity, drawing on the Battleship Oregon Collection of the OHS Research Library and institutional records of the OHS Museum as well as secondary sources that explore the colonial context around museum collecting. The first chapter will show …
