Chemical Interactions And Cytotoxicity Of Terpene And Diluent Vaping Ingredients, Yanira Baldovinos, Alexandra Archer, James C. Salamanca, Robert M. Strongin, Christie Sayes

Chemistry Faculty Publications and Presentations

Vaping devices have risen in popularity since their inception in 2007. The practice involves using a variety of commercially available devices. Internal heating systems in devices aerosolize e-liquid formulations of complex mixtures including an active ingredient (e.g., THC, CBD, and nicotine), diluents (or cutting agents), solvents, and flavoring agents (e.g., terpenes and aldehydes). The vaping toxicology literature consists of cytotoxicity studies of individual chemicals and commercial formulas. Because of the variation of e-liquid composition, there is a limited understanding of the toxicity of ingredient combinations. This study analyzed the cytotoxic effects after exposure to individual and binary mixtures of a …

Stable Coexistence Or Competitive Exclusion? Fern Endophytes Demonstrate Rapid Turnover Favoring A Dominant Fungus, Brett Steven Younginger, Nathan U. Stewart, Mehmet Ali Balkan, Daniel J. Ballhorn

Biology Faculty Publications and Presentations

Fungal endophytes are critical members of the plant microbiome, but their community dynamics throughout an entire growing season are underexplored. Additionally, most fungal endophyte research has centred on seed-reproducing hosts, while spore-reproducing plants also host endophytes and may be colonized by unique community members. In order to examine annual fungal endophyte community dynamics in a spore-reproducing host, we explored endophytes in a single population of ferns, Polystichum munitum, in the Pacific Northwest. Through metabarcoding, we characterized the community assembly and temporal turnover of foliar endophytes throughout a growing season. From these results, we selected endophytes with outsized representations in …

Respawning Jihadist: Isis Recruiting Through Online Gaming Communities, Alexander J. Ham-Kucharski

Student Work

The purpose of my research is to educate and bring awareness of ISIS’s (Islamic State of Iraq and Syria) recruiting programs through social media and video games. As stated by Lakomy (2019): “Cyber jihadis nowadays rightly perceived as a rising threat to international security” (2019, p. 383). ISIS targets individuals as young as teenagers through games such as Call of Duty, Far Cry, Halo, ARMA3, and Grand Theft Auto as to recruit those from the Western world for their Jihad. ISIS Recruiters use these platforms to attract initiates via the gaming world through imagery that …

Arts For Whose Sake? Arts Course-Taking And Math Achievement In Us High Schools, Daniel Mackin Freeman, Dara Shifrer

Sociology Faculty Publications and Presentations

Math achievement in U.S. high schools is a consistent predictor of educational attainment. While emphasis on raising math achievement continues, school-level interventions often come at the expense of other subjects. Arts courses are particularly at risk of being cut, especially in schools serving lower socioeconomic status youth. Evidence suggests, however, that arts coursework is beneficial to many educational outcomes. We use data on 20,590 adolescents from the High School Longitudinal Study of 2009 to answer two research questions: (1) Does student accumulation of fine arts courses across different topic areas relate positively to math test scores in high school? (2) …

This presentation focuses on getting past political and social divisiveness. Professor Horowitz has taught at Portland State since 1968, where he won a prize for outstanding achievement in 2007. He is co-author of a U.S. history textbook and has a number of publications to his credit. He is the author of a personal, professional, and political memoir with the title “Getting There: An American Cultural Odyssey.”

Topological Anomaly Detection In Dynamic Multilayer Blockchain Networks, Dorcas Ofori-Boateng, I. Segovia Dominguez, C. Akcora, M. Kantarcioglu, Y. R. Gel

Mathematics and Statistics Faculty Publications and Presentations

Motivated by the recent surge of criminal activities with cross-cryptocurrency trades, we introduce a new topological perspective to structural anomaly detection in dynamic multilayer networks. We postulate that anomalies in the underlying blockchain transaction graph that are composed of multiple layers are likely to also be manifested in anomalous patterns of the network shape properties. As such, we invoke the machinery of clique persistent homology on graphs to systematically and efficiently track evolution of the network shape and, as a result, to detect changes in the underlying network topology and geometry. We develop a new persistence summary for multilayer networks, …

How Local Stakeholder Stereotypes Impact Liability Of Foreignness And Asset Of Foreignness, Abiodun Ige, Marvin Washington

Business Faculty Publications and Presentations

While it is well known that there are liabilities of foreignness (LOFs) that impact firms as they enter foreign markets, it is less well known how stereotypes held by local stakeholders impact LOFs of foreign firms. Recent research has demonstrated that foreignness can offer benefits, or assets of foreignness (AOFs), for firms as they enter foreign markets. While research is growing in this area, there remains a gap in our understanding of how local stakeholders evaluate foreign firms. We leverage the stereotype content model, which measures dimensions of warmth and competence, to demonstrate that a foreign firm can enjoy an …

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 …

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 …

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 …

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 …

Avatar: The New Employee? Creating Online Employment Personas May Benefit Stigmatized Employees, Esenaman Batirov, Larry R. Martinez

Psychology Faculty Publications and Presentations

Although we appreciate and agree with the conclusions that (Wilcox et al., 2022) come to in their review of the literature related to cybervetting, our intention in this response is to discuss the potential utility of cybervetting in a post-COVID world in which fully remote employment is much more prevalent. Specifically, we draw parallels to other contexts in which individuals interact completely remotely successfully and highlight how such arrangements can actually be beneficial —rather than detrimental—to employees with stigmatized identities or characteristics.

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 …

An Analysis Of The Strengths And Weaknesses Of The Tulsa Remote Program, As An Effective Economic Development Strategy, Kristen J. Padilla

Dissertations and Theses

Cities do not exist in a vacuum. They are in constant competition for talented, educated individuals and growing, innovative businesses -even if that competition is not explicit or specific. Traditionally cities have been left with two economic development paths to help diversify their economies: attract talent but without jobs, or attract business but without a strong talent pool. However, due to technological advancements, exacerbated by the pandemic, a new and growing workforce that can work from anywhere has emerged, remote workers. This talent pool shifts traditional economic development attraction strategies from city to industry to city to talent.

Many remote …

A Look At The Missing And Murdered Indigenous Women Crisis: Investigation Of Potential Causes And Effects, Verity Saige Vogel

University Honors Theses

In North America, Indigenous women go missing and are murdered at a rate higher than any other demographic. Scholars and governmental agencies agree that the Missing and Murdered Indigenous Women (MMIW) crisis is a pressing issue; it was not until a series of successful social media campaigns (using the hashtag #MMIW) and other grassroots activism took root across First Nations and Native communities in North America that the gravity of the situation became widely reported. Although many agree that the MMIW crisis is a wicked problem (in that it has many contributing factors that amplify its effect and contribute to …

Post-Fire Erosional And Hydrological Processes Promoting Debris Flow Initiation In A Douglas Fir And Western Hemlock Forest In The Riverside Burn Area, Oregon, Morena Nicole Hammer

Dissertations and Theses

Post-fire debris flows initiated by overland flow in the Pacific Northwest (PNW) are largely undocumented. Instead, debris flows are typically initiated by shallow landslides that result in a mud slurry of water and sediments traveling downhill under the force of gravity. However, because of the Fall 2020 fires in Oregon, the typical initiation style and erosional patterns in burned catchments may have changed because of unusually high burn severity. Due to the intensity of these fires, we set out to determine how hydrologic processes and erosion occurred, when they occurred, and what process was primarily responsible for the erosion that …

Examining Emergency Citizen Response To The Covid-19 Pandemic: Emergent Groups Addressing Food Insecurity In Portland, Oregon, Aliza Ruth Tuttle

Dissertations and Theses

Emergency response agencies commonly focus on how hard infrastructure will interact with extreme climatic and geologic events: bridges during an earthquake and buildings following a tornado, for example. Peoples' actual experience of these extreme events vary, however, based on socially constructed consequences of natural hazard events and their interaction with a depleted or robust social safety net.

Previous research shows people living with depleted social safety nets and who experience a natural hazard event are likely to help where they see disaster. Individuals consistently form groups, called emergent groups, to organize their efforts. This research explored emergent groups that formed …

A Typology Of Foster Home Quality Elements In Relation To Foster Youth Mental Health, Paul Sorenson

Dissertations and Theses

Foster care has been one of the primary interventions in society's efforts to address child maltreatment. The foster parents and foster homes follow a process of certification intended to ensure that maltreated children be placed in substitute care that supports and encourages positive outcomes. One of the outcomes of principle concern is mental health. Few studies have been conducted that explore the makeup of certified foster homes with respect to the cumulative impact of multiple indicators of quality on mental health outcomes of foster youth.

This study sought to identify a typology of foster homes based on theorized indicators of …

Monetizing Attention And Branding Strategy: Assessing The Effects Of Personal Branding On Amateur Athletic Compensation, Abby Christiansen

University Honors Theses

What role does branding play in the compensation issues faced by amateur athletes? How has the rise of influential online social personas legally impacted their case? This thesis explores the long-standing compensation issues that many amateur athletes have faced while under the control of the NCAA. It connects the social impact of online personal branding to some of the legal victories won by student athletes as they gain more freedom over their NIL (name, image, likeness) by detailing the importance of branding and its evolution into personal branding in a 21^st century economy. Many of the rules and regulations …
