Implications Of Physical Fault Injections On Single Chip Motes, Sara Faour, Mališa Vučinić, Filip Maksimovic, David Burnett, Paul Muhlethaler, Thomas Watteyne, Kristofer Pister

Electrical and Computer Engineering Faculty Publications and Presentations

Single-chip motes are wireless sensor nodes that integrate computation, communication, power and sensing on a single chip. We consider the security threats these novel devices are subject to when employed in safety-critical applications. Fault injection attacks are a prominent form of physical attacks that pose a threat to the normal and secure functioning of targeted devices, potentially compromising their intended behavior. These attacks have been studied mainly on commercial off-the-shelf devices which rely on external components such as crystal oscillators and passives. Such external components are absent from single-chip motes, resulting in a uniquely different attack surface compared to commercial …

#Blackatcmo: Challenging Charter Schools Through Youth Instagram Counterstories, Madhu Narayanan, Matthew Mccluskey

Educational Leadership and Policy Faculty Publications and Presentations

As protests flared in 2020, Black students took to Instagram to voice their experiences at ‘no-excuses’ Charter Management Organizations (CMOs). Such schools have presented a discourse of high achievement and social justice. Yet, in the span of a few weeks, hundreds of posts on Instagram offered rarely heard counter-narratives of the experience of being a student of Color at such schools. This paper analyzes how social media posts combine online discourse and youth culture to provide insight into the racialized experience of schooling. We show how these posts created distinct visual signatures, co-opted the well-crafted narratives of CMOs, and took …

Extensions Beyond Program Impacts: Conceptual And Methodological Considerations In Studying The Implementation Of A Preschool Social Emotional Learning Program, Jaiya Rae Choles, Robert W. Roeser, Andrew Mashburn

Psychology Faculty Publications and Presentations

Social–emotional learning (SEL) programs are frequently evaluated using randomized controlled trial (RCT) methodology as a means to assess program impacts. What is often missing in RCT studies is a robust parallel investigation of the multi-level implementation of the program. The field of implementation science bridges the gap between the RCT framework and understanding program impacts through the systematic data collection of program implementation components (e.g., adherence, quality, responsiveness). Data collected for these purposes can be used to answer questions regarding program impacts that matter to policy makers and practitioners in the field (e.g., Will the program work in practice? Under …

Incentivizing Information Literacy Integration: A Case Study On Faculty–Librarian Collaboration, Jill K. Becker, Samantha Bishop Simmons, Natalie Fox, Andi Back, Betsaida M. Reyes

Communications in Information Literacy

Frequently, information literacy instruction takes the form of a one-shot library session with minimal collaboration between librarians and teaching faculty. To offer an alternative to this model, librarians implemented the Information Literacy Mini-Grant; an incentivized program inviting teaching faculty to collaborate with librarians to redesign an assignment to integrate information literacy into their course. Following the semester-long collaboration, teaching faculty provided written feedback and participated in a panel discussion to share their experiences with the program. This case study examines teaching faculty’s perceptions of collaborating with librarians in the pilot year of the program. Teaching faculty’s feedback provided insights into …

Working Paper No. 67, Insights Into Project Cybersyn, Leah Herrera

Working Papers in Economics

This inquiry seeks to establish that back in the 1970s Chile’s “Project Cybersyn” offered novel approaches and specific technologies that appeared to have benefitted capitalism as a system. The Spanish name, SYNCO served as an acronym for Sistema de Información y Control. President Salvador Allende expected that the attributes associated with Project Cybersyn could assist his efforts in implementing his variant of socialism. Cybersyn consisted of a network (Cybernet), software (Cyberstride), computers, a economic simulator known as CHECO, and a control room (Opsroom.) Cybersyn reached an advanced prototype stage; however, its fate was also tied to the interests of the …

Scientology's Faq: Sciencing, Tech-Romancing, Simulacra, & Simulation An Estranged Content Analysis, David Scott Morrill

Dissertations and Theses

This thesis examines how the practice of sciencing, tech-romancing, simulacra, and simulation manifests in both the text and symbols used on audiences of the Church of Scientology’s outreach materials. It specifically examines its official FAQ page. Self-framing was observed that satisfied the definition of sciencing and tech-romancing. Under an Estranged approach, Morrill examined selections of the Church’s FAQ pages, coding for instances of sciencing, tech-romancing, simulacra, and simulation. The data indicate that the Church frequently adopts simulacra and engages in simulation. The Church was seen frequently adopting technological and scientific symbols and jargon. The degree of sciencing, tech-romancing, simulacra, and …

Spatial Validation Of Agent-Based Models, Kristoffer Wikstrom, Hal T. Nelson

Public Administration Faculty Publications and Presentations

This paper adapts an existing techno–social agent-based model (ABM) in order to develop a new framework for spatially validating ABMs. The ABM simulates citizen opposition to locally unwanted land uses, using historical data from an energy infrastructure siting process in Southern California. Spatial theory, as well as the model’s design, suggest that adequate validation requires multiple tests rather than relying solely on a single test-statistic. A pattern-oriented modeling approach was employed that first mapped real and simulated citizen comments across the US Census tract. The suite of spatial tests included Global Moran’s I, complemented with bivariate correlations, as well as …

Hydraulic Redistribution Under Saline Conditions, Josh Gottlieb

Civil and Environmental Engineering Undergraduate Honors Theses

Water scarcity and soil salinity are dual stressors for plants in arid, salt-affected ecosystems. Hydraulic redistribution, a hydraulic adaptation which moves water through plant roots into dry or saline soil regions along potential gradients, aids plant survival in stressful environments. Recent theory regarding hydraulic redistribution proposes limitations on the process within saline soils. This study applies a minimalist resistor-capacitor model of the soil-plant-atmosphere system to the experimental conditions of a 2010 study investigating hydraulic redistribution in a salt affected area. The effectiveness of the model is evaluated, and a sensitivity analysis is conducted to identify key dynamics affecting the moisture …

Confederate Statues In University Opinion Newspaper Articles: An Analysis Of Themes And Attachment, Jamie Nicole Knopf

Dissertations and Theses

Many have asked for Confederate monuments' removal while others argue that they should remain or be recontextualized. Knopf analyzed themes found in Southern university student newspapers on the monument issue and how the statues related to community attachment. Using thematic analysis, Knopf identified six themes across the articles, and found that both removal and recontextualization arguments refer to the ideology behind the statues and the impacts this can have on students. Instances of attachment were used in both removal and recontextualization articles.

You Need This: Global Fast Fashion, Environment, And Consumption Culture, Alexandra Lamm

Student Work

In looking at how global production of clothing has increased and shifted, we see the impacts in places like workers rights, environmental issues and cultural consumption. Although vastly different, through examination we will see how all are intrinsically linked. We have reached a truly global economy, and even when threatened with negative consequences of mass consumption in our daily lives, the road to actual change in the fashion industry becomes harder in time due to our dependency on the industry as a whole.

Surveilling Threat: The Roles Of Ideology And Threat Perceptions In Support For Islamophobic Policy, Aeleah M. Granger, Kimberly B. Kahn, Joel S. Steele

Psychology Faculty Publications and Presentations

After the attacks on 9/11, Muslims in the United States were the targets of increased surveillance by law enforcement on the basis of their religious identity, often resulting in mistreatment and unjustified imprisonment. The current study examined ideologies that are associated with Islamophobia and support for police surveillance of Muslims, as well as specific types of intergroup threat perceptions that mediate these relationships. Participants (N = 603) completed a survey measuring Social Dominance Orientation (SDO), Right-wing Authoritarianism (RWA), Nationalism, intergroup threat perceptions, Islamophobia, and support for an anti-Muslim police surveillance policy. Results demonstrated that higher levels of SDO, RWA, and …

The Next Wave Of Abolishing Parking Mandates, Catie Gould, Jeannette Lee

PSU Transportation Seminars

The movement to eliminate parking mandates is having a big moment. This summer, both Oregon and California took statewide action to roll back minimum off-street parking requirements, relegalizing homes and businesses regardless of how many parking spots they have. We’ll take a look at why parking reform is so important, what to expect next in Oregon, and lessons from cities who have already gone all the way to delete this regulation from their zoning code.

Results: We recorded 540 incidents, mostly with mammals (N=479); coyotes (Canis latrans) killed 1 074 animals in 183 attacks at 12 farms. We also recorded conflicts with jaguar, Panthera onca, puma, Puma concolor, ocelot, Leopardus …

A First-Tier Framework For Assessing Toxicological Risk From Vaporized Cannabis Concentrates, Shawna Vreeke, David M. Faulkner, Robert Strongin, Echoleah Rufer

Chemistry Faculty Publications and Presentations

Vaporization is an increasingly prevalent means to consume cannabis, but there is little guidance for manufacturers or regulators to evaluate additive safety. This paper presents a first-tier framework for regulators and cannabis manufacturers without significant toxicological expertise to conduct risk assessments and prioritize additives in cannabis concentrates for acceptance, elimination, or further evaluation. Cannabinoids and contaminants (e.g., solvents, pesticides, etc.) are excluded from this framework because of the complexity involved in their assessment; theirs would not be a first-tier toxicological assessment. Further, several U.S. state regulators have provided guidance for major cannabinoids and contaminants. Toxicological risk assessment of cannabis concentrate …

Micrornas Contribute To The Host Response To Coxiella Burnetii, Madhur Sachan, Katelynn Brann, Daniel E. Voth, Rahul Raghavan

Biology Faculty Publications and Presentations

MicroRNAs (miRNAs), a class of small non-coding RNAs, are critical to gene regulation in eukaryotes. They are involved in modulating a variety of physiological processes, including the host response to intracellular infections. Little is known about miRNA functions during infection by Coxiella burnetii, the causative agent of human Q fever. This bacterial pathogen establishes a large replicative vacuole within macrophages by manipulating host processes such as apoptosis and autophagy. We investigated miRNA expression in C. burnetii-infected macrophages and identified several miRNAs that were down- or up-regulated during infection. We further explored the functions of miR-143-3p, an miRNA whose …

Drawing from primary data collection with small brick-and-mortar businesses within the greater metro area of Portland, Oregon, the value of social media is the ability of an organization to create a sense of value for their consumers while promoting positive relations and enhancing the consumer's ability to interact with an organization on a more personal level. Focusing on the implementation of various strategies and promotional efforts to increase the success of these small businesses and align their organizational …

Intersectionality Pertaining To The Disproportionate Rates Of Black Women In Prisons And Jails, Mackenzie Heller

University Honors Theses

The incarceration rates of Black women in America surpass even all other demographics. Yet, Black women are often not on the news when discussing prison rates in the United States. Rather we see Black men, Hispanic men, and so forth. While these people do make up large portions of the prison system they are seeing a decline in their incarceration rates. Black women are often pushed to the sidelines when discussing matters that can be seen as central to their livelihoods.

This thesis addresses the intersectionality that only Black women experience and how that affects their imprisonment rates and experiences …

Working Outside The Binary: Experiences Of Nonbinary Employees In The Workforce, Mordeky C. Dullum

University Honors Theses

Transgender issues in the workplace have only recently become a focus in research, and it is still new and understudied. Even less studied is the demographic of gender expansive individuals including nonbinary and gender non-conforming individuals. This qualitative study aims to explore and highlight workplace experiences for nonbinary people, with a particular focus on younger nonbinary people who experience less employment stability in more public facing jobs. Thirteen participants engaged in interviews where they were asked to describe their experiences dealing with discrimination, harassment and transphobia in the workplace, in addition to sharing their ideas for practical solutions or changes …

Sequential Frame-Interpolation And Dct-Based Video Compression Framework, Yeganeh Jalalpour, Wu-Chi Feng, Feng Liu

Computer Science Faculty Publications and Presentations

Video data is ubiquitous; capturing, transferring, and storing even compressed video data is challenging because it requires substantial resources. With the large amount of video traffic being transmitted on the internet, any improvement in compressing such data, even small, can drastically impact resource consumption. In this paper, we present a hybrid video compression framework that unites the advantages of both DCT-based and interpolation-based video compression methods in a single framework. We show that our work can deliver the same visual quality or, in some cases, improve visual quality while reducing the bandwidth by 10--20%.

K-12 Racial Equity Work In The Predominantly White Pacific Northwest: Interracial Conversations, Counter-Stories, And Considerations, Bradley Justin Parker

Dissertations and Theses

K-12 public education in the United States, post Brown v. Board of Education (1954), has historically maintained a predominantly White teaching force, and has persistently underserved students of Color in terms of academic, social, and emotional outcomes. Additionally, K-12 school-based racial equity work that strives to address the operation of racism is inconsistent, difficult to measure, and has not demonstrably created more racially equitable experiences or outcomes for students or educators of Color. In this project, I critically explore K-12 school-based efforts towards more racial equity in the predominantly White Pacific Northwest, and I take an intentional and critical look …

Teaching And Learning Social Change, Amie Thurber, Helen Buckingham, Jordenn Martens, Rebecca Lusk, Darrylann Becker, Stacey Spenser

School of Social Work Faculty Publications and Presentations

How can social work courses prepare students to be scholars of social movements, and also to act in solidarity with movements for social justice? How can graduate programs reimagine the professional socialization of social work students from aspiring for expertise toward a stance of life-long learning? How can instructors more deeply leverage our teaching practice to advance justice in our communities? This paper traces one attempt to answer these questions through a three-quarter graduate social work course designed to deepen students’ skills and knowledge in practices for social transformation, while amplifying existing social justice movements. Drawing on reflections from the …

Enlarging The Stokes Shift By Weakening The Π-Conjugation Of Cyanines For High Signal-To-Noise Ratiometric Imaging, Yongkang Yue, Tingting Zhao, Zhou Xu, Weijie Chi, Xiaojun Chai, Jiahong Ai, Jiawei Zhang, Fangjun Huo, Robert M. Strongin, Caixia Yin

Chemistry Faculty Publications and Presentations

The signal-to-noise ratio (SNR) is one of the key features of a fluorescent probe and one that often defines its potential utility for in vivo labeling and analyte detection applications. Here, it is reported that introducing a pyridine group into traditional cyanine-7 dyes in an asymmetric manner provides a series of tunable NIR fluorescent dyes (Cy-Mu-7) characterized by enhanced Stokes shifts (≈230 nm) compared to the parent cyanine 7 dye (nm). The observed Stokes shift increase is ascribed to symmetry breaking of the Cy-Mu-7 core and a reduction in the extent of conjugation. The fluorescence signals of the Cy-Mu-7 dyes …

'It’S Just Filth:’ Banned Books And The Project Of Queer Erasure, Caitlin O'Loughlin, Taylor Schmidt, Jocelyn Glazier

Northwest Journal of Teacher Education

This paper seeks to explore the connection between the banning of queer books, the creation of discourses of controversy, and the erasure of queer knowledges and peoples from schools. Using a queer theory-informed approach to critical discourse analysis, we ask how these proposed bans seek to erase queer peoples, how this impacts teachers, and what teacher preparation programs can do to counter these acts of destruction.
