Connected Vehicle System Design For Signalized Arterials, Xianfeng Terry Yang, Mingyue Ji, Qinzheng Wang

TREC Final Reports

It can be expected that connected vehicles (CVs) systems will soon go beyond testbed and appear in real-world applications. To accommodate a large number of connected vehicles on the roads, traffic signal control systems on signalized arterials would require supports of various components such as roadside infrastructure, vehicle on-board devices, an effective communication network, and optimal control algorithms. In this project, we aim to establish a real-time and adaptive system for supporting the operations of CV-based traffic signal control functions. The proposed system will prioritize the communication needs of different types of CVs and best utilize the capacity of the …

Shortening The Age Of Information: Connecting Vehicles To Infrastructure In Real Time, Xianfeng Terry Yang, Mingyue Ji

TREC Project Briefs

Now that we are decades into the Age of Information, it’s increasingly important to minimize the age of information: that is, to make sure the information we have is the very latest. In the world of connected vehicle technology, Age of Information (AoI) is a concept that was introduced in 2012 to quantify the “freshness” of knowledge about the status of remote systems.

The Moderating Effect Of Buying Impulsivity On The Dynamics Of Unplanned Purchasing Motivations, Jacob Suher, Wayne D. Hoyer

Business Faculty Publications and Presentations

Previous studies of in-store decision making have assumed that motivations for unplanned purchases are homogeneous throughout a shopping trip. In response to this assumption, the authors develop a conceptual framework to explain how consumers’ internal (i.e., intrinsic) and external (i.e., extrinsic) motivations for unplanned purchases actually vary during a shopping trip. Two field studies and five online experiments provide evidence that the personality trait of buying impulsivity predicts differences in whether a shopper initially focuses on internal motivations (e.g., “because I love it”) or external motivations (e.g., “because it is on sale”) for unplanned purchases at the beginning of a …

Having All Of Your Internal Resources Exhausted Beyond Measure And Being Left With No Clean-Up Crew’’: Defining Autistic Burnout, Dora Raymaker, Alan R. Teo, Nicole A. Steckler, Brandy Lentz, Mirah L. Scharer, Austin Delos Santos, Steven K. Kapp, Morrigan Hunter, Andee Joyce, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

Background: Although autistic adults often discuss experiencing ‘‘autistic burnout’’ and attribute serious negative outcomes to it, the concept is almost completely absent from the academic and clinical literature.

Methods: We used a community-based participatory research approach to conduct a thematic analysis of 19 interviews and 19 public Internet sources to understand and characterize autistic burnout. Interview participants were autistic adults who identified as having been professionally diagnosed with an autism spectrum condition. We conducted a thematic analysis, using a hybrid inductive–deductive approach, at semantic and latent levels, through a critical paradigm. We addressed trustworthiness through multiple coders, peer debriefing, …

Impact Of The Covid-19 Outbreak On Long-Term Care In The United States, Courtney H. Van Houtven, Nathan A. Boucher, Walter D. Dawson

Institute on Aging Publications

The United States (US) currently has the most confirmed cases of COVID-19 of any country. Yet, adequate testing for the virus remains a major issue. Approximately 51.6 million Americans are over the age of 65 and 56 percent of adults over 65 are living with two or more chronic conditions (23 percent have 3 or more). Given the higher risk of death and complications associated with advanced age and underlying health conditions, COVID-19 has had an immense impact upon LTC in the United States. Yet, the level and intensity of impact has been sporadic in application. This is due in …

Workflow Critical Path: A Data-Oriented Path Metric For Holistic Hpc Workflows, Daniel D. Nguyen

Dissertations and Theses

Optimizing scientific application performance in HPC environments is a complicated task which has motivated the development of many performance analysis tools over the past decades. These tools were designed to analyze the performance of a single parallel code using common approaches such as message passing (MPI), multithreading (OpenMP), acceleration (CUDA), or a hybrid approach. However, current trends in HPC such as the push to exascale, convergence with Big Data, and growing complexity of HPC applications and scientific workflows, have created gaps that these performance tools do not cover, particularly involving end-to-end data movement through an end-to-end HPC workflow comprising multiple …

Extensible Performance-Aware Runtime Integrity Measurement, Brian G. Delgado

Dissertations and Theses

Today's interconnected world consists of a broad set of online activities including banking, shopping, managing health records, and social media while relying heavily on servers to manage extensive sets of data. However, stealthy rootkit attacks on this infrastructure have placed these servers at risk. Security researchers have proposed using an existing x86 CPU mode called System Management Mode (SMM) to search for rootkits from a hardware-protected, isolated, and privileged location. SMM has broad visibility into operating system resources including memory regions and CPU registers. However, the use of SMM for runtime integrity measurement mechanisms (SMM-RIMMs) would significantly expand the amount …

Pro-Life Ends At Birth: Race As A Primary Driver Of State Abortion And Concurrent Natalist Policy, Tasha Danner

University Honors Theses

The year 2019 saw the most restrictive state abortion policies introduced and passed since Roe v Wade. The same states passing this legislation are often states also cutting funding for policies that improve the health and socio-economic mobility of mothers and children, which disproportionately affects African-American residents of those states. Outside of reproductive justice advocacy, there is not much research on the role that race plays in the introduction and passing of state abortion policy. I examine and analyze the role of racial prejudice in passing restrictive abortion policy in southern states. Using historical context in southern states, a survey …

Balancing Security, Performance And Deployability In Encrypted Search, David Joel Pouliot

Dissertations and Theses

Encryption is an important tool for protecting data, especially data stored in the cloud. However, standard encryption techniques prevent efficient search. Searchable encryption attempts to solve this issue, protecting the data while still providing search functionality. Retaining the ability to search comes at a cost of security, performance and/or utility.

An important practical aspect of utility is compatibility with legacy systems. Unfortunately, the efficient searchable encryption constructions that are compatible with these systems have been proven vulnerable to attack, even against weaker adversary models.

The goal of this work is to address this security problem inherent with efficient, legacy compatible …

Minimum Complexity Echo State Networks For Genome And Sequence Analysis, Christopher John Neighbor

Dissertations and Theses

Increasing viral illnesses threatens global human health and welfare. Due to the distribution of disease and the expense of diagnosis, it is of value to develop portable assays that can detect viral infections early. DNA molecular logic technology offers a portable detection method due to the versatility and stability of DNA and the potential of in situ computation.

Top-down engineering of these chemical logic networks can be difficult due to the difficulties of their implementation using DNA as a substrate. In this work echo state networks, a form of recurrent neural networks, were explored with the motivation that their implementation …

Power Efficiency Enhancement And Linearization Techniques For Power Amplifiers In Wireless Communications, Haider Al-Kanan

Dissertations and Theses

Wireless communication systems require Power Amplifiers (PAs) for signal transmissions. The trade-off between power efficiency and nonlinear distortion in PAs degrades the communication performance. Thus, power efficiency and nonlinearity are two main concerns of operating PAs in communication systems. Nonlinear behavioral models are typically used to quantify and mitigate the distortion effects of PAs on communication systems. This dissertation presents an estimation approach for modeling and linearizing the PA Amplitude-to-Amplitude (AM/AM) nonlinearity using the design specifications of PAs, such as gain, the third-order intercept point, and 1dB compression point. Furthermore, an enhanced approach for modeling solid-state power amplifiers is developed …

Tell Me Your Story: Narrative Inquiry In Lis Research, Emily Ford

Library Faculty and Staff Publications and Presentations

Narrative inquiry, a phenomenological qualitative research methodology, examines individual human experiences—stories. Yet, researchers in Library and information science (LIS)—a human-focused profession—have infrequently used it. This article introduces narrative inquiry and provides a literature review of the few LIS studies utilizing it. Next, it extrapolates on Coralie McCormack’s "storying stories," a multi-faceted approach used to analyze narrative inquiry research data. Finally, the article outlines potential uses for narrative inquiry in LIS research.

Legal Geographies And Political Ecologies Of Water Allocation In Maui, Hawai'i, Alida Cantor, Kelly Kay, Chris Knudson

Geography Faculty Publications and Presentations

Throughout the Hawaiian Islands, sugar plantations have controlled a large proportion of water resources for over a century, often leaving little water in streams to support ecosystems or Native Hawaiian cultural and agricultural practices. Recently, in Maui, Hawai‘i, community activists and lawyers representing Native Hawaiian and environmental interests have successfully reclaimed water resources for instream flow utilizing legal processes and tools such as Hawai‘i’s public trust doctrine, which has plural roots in both Hawaiian and Western legal traditions. In this paper, we use qualitative fieldwork, including interviews, participant observation, and archival data collection, to explore two recent and ongoing legal …

Are The Goals Of Sustainability Interconnected? A Sociological Analysis Of The Three E’S Of Sustainable Development Using Cross-Lagged Models With Reciprocal Effects, Matthew Thomas Clement, Nathan Pino, Patrick Greiner, Julius A. Mcgee

Sociology Faculty Publications and Presentations

Conceptual discussions of sustainability emphasize the interdependent relationship between relevant social and environmental factors. Yet, traditional quantitative analyses of the topic have tended to estimate the exogenous or direct/indirect effects a predictor variable has on a particular measure of sustainability. We examine the endogenous, interdependent relationship between the three E’s of sustainability (economy, equity, and ecology), incorporating country-level data for 1990 through 2015 into cross-lagged structural equation models with reciprocal and fixed effects. Results from these longitudinal models suggest that over time, at the country level, increasing economic inequality reduces renewable energy consumption, with no evidence of reciprocal feedback. Keeping …

Portland Parks & Recreation: Funding And Financial Impact Analysis, Peter Hulseman, Katelyn Kelley, Hoang Nguyen, Emma Brophy, Northwest Economic Research Center

Northwest Economic Research Center Publications and Reports

For this report, the Northwest Economic Research Center (NERC) investigated six potential revenue generating measures, as requested by Portland Parks and Recreation (PP&R). This research includes an analysis of the revenue potential for each tax, the impacts of compression in property taxes, and an assessment of tax incidence.

Three of the funding options investigated are forms of property tax: a temporary local option tax, a permanent special district tax, and a general bond obligation. Using 2017 property tax data, NERC built a model that simulates these tax increases for each tax lot in Portland. The growth of Assessed Value (AV) …

Understanding Individual And Family Experiences Associated With Dup: Lessons From The Early Assessment And Support Alliance (Easa) Program In Oregon, Usa, Ryan P. Melton, Shannon Blajeski, Diana Glasser

Regional Research Institute for Human Services

Research shows that a longer duration of untreated psychosis (DUP) is associated with worse psychiatric outcomes, with average length of DUP of 73 weeks in the U.S. The aim was to examine the DUP period for first episode psychosis in Oregon, with a focus on the processes between the first positive symptoms and first treatment. To investigate DUP, researchers used methods consistent with grounded theory to collect data from 9 participants and their families about the process between onset of psychotic symptoms and entrance into treatment. Results suggest that recognition of symptoms was the primary driver of help-seeking in this …

“Le Soleil De France”: Warm Translations Of Guy De Maupassant In Works By Isaak Babel’ And Ivan Bunin, Cassio De Oliveira

World Languages and Literatures Faculty Publications and Presentations

In the wake of Lev Tolstoi’s appraisals of his work, Guy de Maupassant was embraced by Russian twentieth-century authors who admired his mastery of the short story. The Soviet writer Isaak Babel’ and the émigré writer Ivan Bunin reference stories and other texts by Maupassant in their stories ‘Guy de Maupassant’ and ‘Bernard’. To these authors, Maupassant constitutes a means of expressing their own outlook on the craft of literature. Mediated by the act of translation from French into Russian, Maupassant’s writing enables the Russian authors to articulate distinct identities regarding their national literature: as Soviet and émigré.

Improved Denoising Of Structural Vibration Data Employing Bilateral Filtering, Ning Liu, Thomas Schumacher

Civil and Environmental Engineering Faculty Publications and Presentations

With the continuous advancement of data acquisition and signal processing, sensors, and wireless communication, copious research work has been done using vibration response signals for structural damage detection. However, in actual projects, vibration signals are often subject to noise interference during acquisition and transmission, thereby reducing the accuracy of damage identification. In order to effectively remove the noise interference, bilateral filtering, a filtering method commonly used in the field of image processing for improving data signal-to-noise ratio was introduced. Based on the Gaussian filter, the method constructs a bilateral filtering kernel function by multiplying the spatial proximity Gaussian kernel function …

Asian American Women In Leadership And Abusive Supervision, Mari A. Wu

University Honors Theses

Drawing on the shifting standards theory, intersectionality theory, double jeopardy theory, the lack of fit model and role congruity theory, I investigate whether there are differences in perceptions of abuse as a function of leader race (i.e., Asian and White) among women. Participants completed a Qualtrics survey in which they evaluated photos of Asian and White women supervisors and indicated the extent to which they believed the person in the photo would be abusive. Results did not reveal a significant difference in perceptions of abuse, but did reveal a significant difference in favor of Asian leaders in perceptions of friendliness …

Dynamic Assessment For Evaluating Bilingual Children's Potential For Language Development Over Time: A Pilot Study, Camryn R. Perez

University Honors Theses

Dynamic assessment for children of diverse cultural or linguistic backgrounds has been developed within multiple language domains and found as a valid measure for diagnosing a developmental language disorder. However, there remains a need to research its efficacy and stability over time. This study examined the predictive validity of dynamic assessment through a comparison of changes in performance over time as well as the relationship between dynamic assessment scores with grammaticality and mean length of utterance. Using pilot data from a larger project, seven Spanish-English bilingual children’s performance on dynamic assessment tasks of word and rule learning was examined over …
