Operating Strategy For Semiconductor Industry During Covid 19: Pandemic Working Model, Anurag Yaddanapudi, Evan Ide, John Matthew, Breault Plummer, Kaushik Chaudhary, Liliana Fitzpatrick, Nader Morgan, Nisha Hemantha Raju, Preston Khiev

Engineering and Technology Management Student Projects

The impacts of the COVID-19 pandemic have been felt across various industries around the world, including the semiconductor industry. The semiconductor industry was boosted by pandemic restrictions as changing consumer habits—driven by the rise in remote work, distance learning, gaming, entertainment, and internet shopping—significantly increased demand for consumer electronic devices to the point that demand for semiconductors far outpaced production. Given the globality and complexity of the semiconductor supply chain, many companies are exploring ways to permanently change workplace collaboration for their employees. In this paper, the Hierarchical Decision Modeling (HDM) method is used to evaluate four possible pandemic semiconductor …

Changes To California Alfalfa Production And Perceptions During The 2011-2017 Drought, Alida A. Cantor, Bethani Turley, Charles Cody Ross, Mathern Glass

Geography Faculty Publications and Presentations

California experienced a severe multiyear drought stretching from 2011 through 2017, significantly reducing surface water supply for ecosystems, agriculture, and humans and prompting coordinated conservation efforts. Given that agriculture is the largest consumptive use of water in the state, one anticipated response to a severe drought would be to decrease production of low-value, high-water-use crops such as alfalfa. In this article we use a multimethod approach to examine both spatial distribution and public perceptions of alfalfa production in California over the course of the 2011 through 2017 drought. We find that although California alfalfa production did decline at the state …

Carli Creek Regional Water Quality Project: Assessing Water Quality Improvement At An Urban Stormwater Constructed Wetland, Christopher L. Desiderati

Environmental Science and Management Professional Master's Project Reports

Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physicochemical, and biological principles such as settling, adsorption, or plant and algae uptake. The efficacy of constructed wetlands for pollutant …

Tools For Addressing Intimate Partner Violence And Suicide Risk: Lessons Learned From Oha’S Covid-19 Emergency Response For Suicide Prevention Grant, Karen Cellarius, Aliza Tuttle, Lea Sevey

Regional Research Institute for Human Services

In August 2020, the Oregon Coalition Against Domestic and Sexual Violence (OCADSV), the Oregon Health Authority (OHA), and Portland State University’s Regional Research Institute for Human Services (PSU RRI) began an 18-month collaboration to strengthen support for domestic violence and mental health agencies during COVID-19. As part of this grant, six domestic violence advocacy organizations around Oregon were able to place co-located advocates with their mental health partner agencies for services and cross-training. The content of this booklet is another product of this collaboration.

Music: Modernist Remediation And Technologies Of Listening, Josh Epstein

English Faculty Publications and Presentations

Excerpt:
Ludwig van Beethoven, if not exactly a modernist, offers ample fodder for modern artists looking to defend – or expand – their turf. While producing City Lights (1928), Charlie Chaplin responded to the newly popular ‘talkies’ by proclaiming that ‘Moving pictures need sound as much as Beethoven symphonies need lyrics’ (qtd. in Crafton 1999: 296).

Patterns Of Interdisciplinary Collaboration Resemble Biogeochemical Relationships In The Mcmurdo Dry Valleys, Antarctica: A Historical Social Network Analysis Of Science, 1907–2016, Stephen M. Chignell, Adrian Howkins, Poppie Gullett, Andrew G. Fountain

Geology Faculty Publications and Presentations

Co-authorship networks can provide key insights into the production of scientific knowledge. This is particularly interesting in Antarctica, where most human activity relates to scientific research. Bibliometric studies of Antarctic science have provided a useful understanding of international and interdisciplinary collaboration, yet most research has focused on broad-scale analyses over recent time periods. Here, we take advantage of a ‘Goldilocks’ opportunity in the McMurdo Dry Valleys, an internationally important region of Antarctica and the largest ice-free region on the continent. The McMurdo Dry Valleys have attracted continuous and diverse scientific activity since 1958. It is a geographically confined region with …

Species-Specific Interactions In Avian–Bryophyte Dispersal Networks, Matthew Chmielewski, Sarah Eppley

Biology Faculty Publications and Presentations

Studies from seed plants have shown that animal dispersal fundamentally alters the success of plant dispersal, shaping community composition through time. Our understanding of this phenomenon in spore plants is comparatively limited. Though little is known about species-specific dispersal relationships between passerine birds and bryophytes, birds are particularly attractive as a potential bryophyte dispersal vector given their highly vagile nature as well as their association with bryophytes when foraging and building nests. We captured birds in Gifford Pinchot National Forest to sample their legs and tails for bryophyte propagules. We found 24 bryophyte species across 34 bird species. We examined …

Mass Timber Building Life Cycle Assessment Methodology For The U.S. Regional Case Studies, Hongmei Gu, Shaobo Liang, Francesca Pierobon, Maureen Puettmann, Indroneil Ganguly, Cindy Chen, Rachel Pasternack, Mark Wishnie, Susan Jones, Ian Maples

Publications, Reports and Presentations

The building industry currently consumes over a third of energy produced and emits 39% of greenhouse gases globally produced by human activities. The manufacturing of building materials and the construction of buildings make up 11% of those emissions within the sector. Whole-building life-cycle assessment is a holistic and scientific tool to assess multiple environmental impacts with internationally accepted inventory databases. A comparison of the building lifecycle assessment results would help to select materials and designs to reduce total environmental impacts at the early planning stage for architects and developers, and to revise the building code to improve environmental performance. The …

Comparative Lcas Of Conventional And Mass Timber Buildings In Regions With Potential For Mass Timber Penetration, Maureen Puettmann, Francesca Pierobon, Indroneil Ganguly, Hongmei Gu, Cindy Chen, Shaobo Liang, Susan Jones, Ian Maples, Mark Wishnie

Publications, Reports and Presentations

Manufacturing of building materials and construction of buildings make up 11% of the global greenhouse gas emission by sector. Mass timber construction has the potential to reduce greenhouse gas emissions by moving wood into buildings with designs that have traditionally been dominated by steel and concrete. The environmental impacts of mass timber buildings were compared against those of functionally equivalent conventional buildings. Three pairs of buildings were designed for the Pacific Northwest, Northeast and Southeast regions in the United States to conform to mass timber building types with 8, 12, or 18 stories. Conventional buildings constructed with concrete and steel …

Working Paper No. 53, Mexico Under Neoliberalism, Daniela M. Ávila Arévalo

Working Papers in Economics

This inquiry seeks to establish that a set of policies that can be identified as ‘neoliberalism’ has generated observable effects on the economy and society of Mexico. Initiated during the last decades of the twentieth century, a combination of external and internal interests led to the implementation of neoliberal policies. The marketization of Mexico’s economy during the 1980s and 90s consolidated ‘structural adjustments.’ Through extensive privatization of what were statist assets, combined with the deregulation of trade as well as numerous aspects of private sector activity, the Mexican economy came to rely upon a low-wage labor export-model that also undermined …

Virology: Mutagenizing The Proteolytic Cleavage Site In The Major Capsid Protein In Ssv1, Thejanee Liyanaarachchi

University Honors Theses

SSV1, spindle-shaped virus 1, is an archaeal virus with a unique shape that belongs to the family of fuselloviruses and infects hyperthermophilic archaea that thrive at 80°C and pH 3. SSV1 has two capsid proteins, VP1 and VP3, that presumably produce the lemon-shaped virion structure characteristic of fuselloviruses. The VP1 amino acid sequence is highly conserved among SSVs. Here, we investigate the importance of the proteolytic cleavage site in position E66 in VP1 by changing its glutamic acid to the other 19 amino acids. We have developed a new protocol for creating SSV1 mutants through HiFi Assembly (NEB) to increase …

An Investigation Into The Relationship Between Obstetric Racism And Postpartum Depression In Black Women, Miguel A. Claxton Iii

University Honors Theses

Postpartum depression is the most common postpartum mood disorder, with 13% of new mothers reporting symptoms within the first year. Adverse birth outcomes, such as low birth weight and preterm birth co-index with the development of postpartum depression. This correlation is particularly alarming considering that Black women have about a 60% higher rate of preterm birth and an 88% higher rate of low birth weight infants than Caucasian women. By utilizing theories of stratified reproduction, necropolitics, and obstetric racism, this paper aims to situate postpartum depression in Black women as a psychological response to systems of medicolegal control and domination. …

Collaborative Digital Problem-Solving: Power, Relationships, And Participation, Gloria E. Jacobs, Jill Castek

Applied Linguistics Faculty Publications and Presentations

The study examines the collaborative nature of problem solving as dyads and triads of adults were grouped to solve digital problems using online resources. Digital problem solving involves the nimble use of skills, strategies, and mindsets to navigate online in everyday contexts using novel resources, tools, and interfaces, in efficient and flexible ways, to accomplish personal and professional goals. Findings address the nature of collaborative talk during digital problem solving through three interrelated categories of themes gleaned from discourse analysis: (a) power, (b) relationships, and (c) participation. These themes offer a nuanced understanding of collaborative interactions during digital problem solving. …

Methods Of Memorialization: Holocaust Commemoration In The United States Holocaust Memorial Museum, Kylee Bolinger

University Honors Theses

Memorials, both formal and informal, both private and public, have long participated in the pursuit to honor the victims of tragedy, disaster, or genocide. Memorial museums serve both to memorialize victims and to foster an environment conducive to reflection and education about these stories. Such memorial museums have especially made their mark after one of the most notable and devastating genocide events in history: the Holocaust in twentieth-century Europe. This thesis examines how memorialization methods utilized by the United States Holocaust Memorial Museum (USHMM) make up the American interpretation of Vergangenheitsbewältigung, the concept typically applied to how Germans deal …

Understanding The Effect Of Dietary Palmitic Acid On Glycolysis During Innate Immune Memory In Macrophages, Khaleda A. Aqaei

PSU McNair Scholars Online Journal

Trained immunity is long-term innate immune memory induced by a primary stimulus, which leads to hyper-inflammation upon secondary stimulation with a homologous or heterologous ligand. Trained immunity is mediated by epigenetic and metabolic reprogramming of the target cell and leads to modification of gene expression and cellular function. Classically, trained immunity is initiated by b-glucans, an inflammatory molecule found on the exterior of fungal species. Interestingly, our lab has recently described that dietary fatty acids can initiate trained immunity, working through similar pathways as b-glucans. Specifically, our data show that a pre-treatment with a specific dietary saturated fatty acid (SFA), …

When A Ban Is Not A Ban: Institutional Work And The Russian Doping Scandal, Mathew Dowling, Spencer Harris, Marvin Washington

Business Faculty Publications and Presentations

There are fewer cases of such blatant acts to defy and subsequent heroic efforts to rearrange institutional norms than the Russian doping scandal. In adopting a neo-institutional perspective, the authors theorize the scandal as a case of attempted but failed institutional disruption. More specifically, the authors draw upon the institutional change literature and the institutional work perspective to explain the key events surrounding actors’ response to the scandal. The analysis utilized Gioia’s methodological approach to examine secondary empirical data. Findings reveal how stakeholders circumvented traditional governance structures in an attempt to disrupt institutional arrangements, but despite this, much of the …

The Game Of Life: How Playing Gamified Interactive Narratives Affects Career Planning In Cambodia, Lauren B. Frank, Paul Sparks, Sheila T. Murphy, Lizzie Goodfriend, Paul Falzone

Communication Faculty Publications and Presentations

To improve economic opportunity in Cambodia, we used social cognitive theory to develop gamified, interactive narratives using mobile phones. Participants guided their chosen character toward their “dream job” goal while encountering a series of barriers along the way. Participants (N = 1,625) were randomly assigned to one of four message frequency experimental conditions: a no-play control condition or playing the interactive narrative one, two, or five times. Compared with not playing the interactive narrative (control), those who played showed higher perceived self-efficacy, response efficacy, and behavioral intentions. Playing more times was associated with less attentional focus and enjoyment, but greater …

2d Vs 3d Tracking In Bacterial Motility Analysis, Jacqueline Acres, Jay Nadeau

Physics Faculty Publications and Presentations

Digital holographic microscopy provides the ability to observe throughout a large volume without refocusing. This capability enables simultaneous observations of large numbers of microorganisms swimming in an essentially unconstrained fashion. However, computational tools for tracking large 4D datasets remain lacking. In this paper, we examine the errors introduced by tracking bacterial motion as 2D projections vs. 3D volumes under different circumstances: bacteria free in liquid media and bacteria near a glass surface. We find that while XYZ speeds are generally equal to or larger than XY speeds, they are still within empirical uncertainties. Additionally, when studying dynamic surface behavior, the …

Reducing Transphobic Attitudes: A Cross-National Investigation Of College Students In Japan And The United States, Kazusa Seko

Dissertations and Theses

Transgender people routinely experience discrimination and mistreatment. Although transphobic attitudes vary from country to country, a more in-depth understanding of these attitudes is needed. Using a semi-structured online survey, this study investigates college students' attitudes toward transgender people in Japan and the United States, a cross-national comparison that aims to deepen our understanding of how transphobic attitudes are shaped and what opportunities exist to reduce transphobia amongst college students. Results show that Japanese students express more transphobic attitudes than U.S. students do; and that U.S. students had more experience with gender-based educational content and were more likely to know someone …

For Fall 2021 Art & Social Practice History at Portland State University, I explored the social simulation game Animal Crossing: New Horizons (ACNH) as a digital altar. I asked How do social simulation games provide a dream space, a neighborhood btwn IRL and URL relationships? How is online gardening similar to sanctuary making, altar making? My co-conspirators offered me Fuck Tom Nook. In other words, should we build an altar in a capitalist, escapist, and colonialist dystopia? This project …

Timber Constructed: Towards An Alternative Material History, Laila Seewang, Irina Davidovici

School of Architecture Faculty Publication and Presentations

Editorial:

This issue of Architectural Theory Review proposes an alternative intellectual history of timber architecture. It foregrounds the relationships that tie the natural resource to the cultural artefact, its processing into construction material and, with it, the production of associated disciplinary expertise. The essays explore the spatial and symbolic possibilities of timber in historical and contemporary discourse by highlighting its simultaneity as cultural artefact, material commodity, environmental resource, and structural element. Thus, the material’s appearance and representation are positioned within perennial oscillations between globalism and locality, natural and man-made, industry and craft, innovation and tradition, material and ideology, modernity and …

Information Literacy For Global Inclusion: Designing An Annotated Bibliography For Global Search And Selection, Pamela A. Espinosa De Los Monteros, Elizabeth L. Black

Can A Large-Landscape Conservation Vision Contribute To Achieving Biodiversity Targets?, Mark Hebblewhite, Jodi A. Hilty, Sara Williams, Harvey Locke, Charles Chester, David Johns, Gregory Kehm, Wendy L. Francis

Political Science Faculty Publications and Presentations

Founded in 1993, the Yellowstone to Yukon (Y2Y) vision was one of the earliest large-landscape conservation visions. Despite growing recognition of large-landscape conservation strategies, there have been few tests to date of conservation gains achieved through such approaches. We tested for conservation gains in the Y2Y region of North America following initiation of the Y2Y conservation vision in 1993 using a counterfactual spatiotemporal comparison and tracking change in five different conservation metrics. First, we enumerated the area of land within Y2Y in designated protected areas. We then compared the rate of change of protected area growth before- and after-initiation of …

Reflections On Teaching Against White Supremacy During A Time Of Social Rupture And Transformation, Erica Fonesca, Stéphanie Wahab

School of Social Work Faculty Publications and Presentations

Social Justice and Social Work is a foundational course required for all social work students in the master’s of social work program at Portland State University. Although the course has long focused on interrupting oppressions including White supremacy, teaching the course during the fall of 2020 required a nimble dance between our familiar modes of teaching and the need for spontaneous adaptation and creativity. The unique landscape for this course included teaching the course remotely (Zoom), inside a university embattled around the arming of its security force (that killed a Black man in 2018), in a city targeted by an …

Tactile Materials In Practice: Understanding The Experiences Of Teachers Of The Visually Impaired, Mahika Phutane, Julie Wright, Brenda Veronica Castro, Lei Shi, Simone R. Stern, Holly Lawson, Shiri Azenkot

Special Education Faculty Publications and Presentations

Teachers of the visually impaired (TVIs) regularly present tactile materials (tactile graphics, 3D models, and real objects) to students with vision impairments. Researchers have been increasingly interested in designing tools to support the use of tactile materials, but we still lack an in-depth understanding of how tactile materials are created and used in practice today. To address this gap, we conducted interviews with 21 TVIs and a 3-week diary study with eight of them. We found that tactile materials were regularly used for academic as well as non-academic concepts like tactile literacy, motor ability, and spatial awareness. Real objects and …
