Transformation Of Tfb2 Overexpression Plasmid Into Hyperthermophile Pyrococcus Furiosus Com1, Brent Marsonette

University Honors Theses

Pyrococcus furiosus is an exceptional model organism for studies of life in extreme environments. Being a hyperthermophile, this archaeal species thrives at temperatures nearing that of boiling water. The underlying machinery for transcription in most archaeal species is poorly studied, and data concerning transcriptional regulation is limited. Transcription Factor B Subunit II (TFB2), a non-standard component of the transcription preinitiation complex in P. furiosus, is poorly understood regarding its function and mechanism. One hypothesis is that TFB2 is important for cellular response to oxidative stress. To test this, a plasmid that over-expresses the TFB2 protein was successfully transformed into …

Pilot Study On The Impact Of Green Roofs On Ozone Levels Near Building Ventilation Air Supply, Pradeep Ramasubramanian, Olyssa Starry, Todd Rosenstiel, Elliott T. Gall

University Honors College Faculty Publication and Presentations

Outdoor air is often introduced into commercial buildings from ventilation intakes sited on rooftops where vegetation (a green roof) is increasingly present. Little is known about the impact of green roofs on the quality of building outdoor ventilation air supply. In this study, we investigated the potential for green roofs to impact ozone (O₃) levels in ventilation air by parameterizing O₃ dry deposition to vegetation and substrate typical of extensive green roofs in field and laboratory studies. Values obtained constrain a 2-D advection-diffusion model of O₃ transport and reaction at the rooftop scale. The 10^{th …}

Webinar: Rethinking Streets For Bikes: An Evidence Based Guide Of Bike-Friendly Street Retrofits, Marc Schlossberg, Roger Lindgren

TREC Webinar Series

There is a growing demand for better infrastructure and fewer barriers to biking and other forms of space-efficient micromobility. Tackling daily trips by bike is easier on the environment, healthier for users and non-users alike, uses precious urbanized public and private land more efficiently, costs taxpayers less to build and maintain infrastructure, and when routes are safe and comfortable, moving by bike is also fun! Complete Streets policies are being adopted across the country, and there is an active conversation around the safety imperative of a Complete Streets approach. Yet, local officials often need both design guidance and the …

Webinar: Words Matter: Recognizing And Addressing Modal Assumptions To Shift Transportation Culture, Barb Chamberlain

TREC Webinar Series

Search #DriverNotCar or #CrashNotAccident on Twitter and you’ll find a vigorous discussion about the power of word choices to shape our understanding of what happens on the street and who’s responsible. When we directly examine and discuss the language we use, we acknowledge its power both to reflect existing attitudes and to shape developing attitudes. This presentation will uncover embedded biases or assumptions in common transportation terminology and provide tips and tools to help us broaden our inclusion of everyone we are supposed to serve as transportation professionals.

Appetite For Growth: Challenges To Scale For Food And Beverage Makers In Three Us Cities, Greg Schrock, Marc Doussard, Laura Wolf-Powers, Steven Marotta, Max Eisenburger

Urban Studies and Planning Faculty Publications and Presentations

Food and beverage (FaB) manufacturing represents a promising opportunity for small-scale “makers” and local economic development. The growth of entrepreneurial maker businesses can be understood in terms of segmentation of market demand, emergence of new intermediaries, and availability of affordable production infrastructure. Yet the ease of starting maker businesses stands in contrast with the challenges of achieving growth and scale as a manufacturer. Through semistructured interviews with 31 FaB makers in Chicago, New York City, and Portland, Oregon, the authors analyze the challenges facing maker–entrepreneurs in this sector. The authors find that the everyday character of food and the relative …

Addressing Changing Demographics In Environmental Justice Analysis, State Of Practice, Aaron Golub, Les Brown, Michael Grant, Nathan Mcneil, Charles Ryerson, Matt Gray, Stephanie Lonsdale, Madison Levy

TREC Final Reports

This report documents how metropolitan planning organizations (MPO), State departments of transportation (DOT), and other transportation agencies are adapting Environmental Justice (EJ) analysis techniques to understand transportation impacts in communities undergoing rapid demographic change. The report also highlights national demographic trends, showing significant change in the size and location of low-income and minority households. These changes are documented in a series of State- and county-level maps demonstrating absolute and percent change in minority populations, low-income populations and limited English proficiency populations between the 1990 – 2010 decennial census periods. Based on the state of practice review, the report also highlights …

Parallelized Particle Swarm Optimization To Estimate The Heat Transfer Coefficients Of Palm Oil, Canola Oil, Conventional, And Accelerated Petroleum Oil Quenchants, Zoltán Fried, Imre Felde, Rosa L. Simencio Otero, Jônatas M. Viscaino, George E. Totten, Lauralice Canale

Mechanical and Materials Engineering Faculty Publications and Presentations

An inverse solver for the estimation of the temporal-spatial heat transfer coefficients (HTC), without using prior information of the thermal boundary conditions, was used for immersion quenching into palm oil, canola oil, and two commercial petroleum oil quenchants. The particle swarm optimization (PSO) method was used on near-surface temperature-time cooling curve data obtained with the so-called Tensi multithermocouple, and a 12.5 by 45 mm Inconel 600 probe. The fitness function to be minimized by a PSO approach is defined by the deviation of the measured and calculated cooling curves. The PSO algorithm was parallelized and implemented on a graphics accelerator …

Inferring And Explaining, Jeffery L. Johnson

PDXOpen: Open Educational Resources

Inferring and Explaining is a book in practical epistemology. It examines the notion of evidence and assumes that good evidence is the essence of rational thinking. Evidence is the cornerstone of the natural, social, and behavioral sciences. But it is equally central to almost all academic pursuits and, perhaps most importantly, to the basic need to live an intelligent and reflective life.

The book further assumes that a particular model of evidence— Inference to the Best Explanation—not only captures the essence of (good) evidence but suggests a very practical, and pedagogically useful, procedure for evidence evaluation. The book is intended …

Stigmatization And Mental Illness: The Communication Of Social Identity Prototypes Through Diagnosis Labels, Justin Samuel Leverett

Dissertations and Theses

This study tested whether participants exposed to a vignette describing an individual experiencing symptoms of depression, which included only the specific diagnosis label of "depression," would report significantly less stigmatized responses than participants exposed to an otherwise identical vignette which included only the non-specific diagnosis label "mental illness." The study is grounded in past research on stigmatization of mental illness and is informed by three theoretical frameworks, the social identity perspective, attribution theory, and labeling theory. Participants were randomly assigned to read one of the two alternate vignettes, then respond to a series of measures testing desire for social distance, …

Frequency Of Social Contact In-Person Vs. On Facebook: An Examination Of Associations With Psychiatric Symptoms In Military Veterans, Alan R. Teo, Benjamin K. Chan, Somnath Saha, Christina Nicolaidis

School of Social Work Faculty Publications and Presentations

Introduction: Social isolation is closely associated with negative mental health outcomes. Social media platforms may expand opportunities for social contact, but whether online interactions are as effective as face-to-face, or in-person, interactions at protecting against the negative effects of social isolation is unclear.

Methods: Participants consisted of U.S. military veterans who served since September 2001 and used Facebook (n = 587). Our independent variables were frequency of social contact occurring in-person and on Facebook. Dependent variables were probable psychiatric disorders and suicidality, measured using several validated screening tools. The independent effect of each form of social contact was assessed using …

Rapid Serial Visual Presentation Interacts With Ambiguity During Sentence Comprehension, Sarah Key-Delyria, Todd Bodner, Lori J. P. Altmann

Psychology Faculty Publications and Presentations

Conventional opinion about using Rapid Serial Visual Presentation (RSVP) for examining sentence comprehension maintains that RSVP taxes working memory (WM), which probably affects sentence processing. However, most RSVP studies only infer the involvement of WM. Other cognitive resources, such as cognitive control or vocabulary may also impact sentence comprehension and interact with RSVP. Further, sentence ambiguity is predicted to interact with RSVP and cognitive resources to impact sentence comprehension. To test these relationships, participants read ambiguous and unambiguous sentences using RSVP and Whole-Sentence presentation, followed by comprehension questions that were targeted to the ambiguous region of the sentences. Presentation type …

Evaluating The Impact And Distribution Of Stormwater Green Infrastructure On Watershed Outflow, Benjamin Fahy

Dissertations and Theses

Green Stormwater Infrastructure (GSI) has become a popular method for flood mitigation as it can prevent runoff from entering streams during heavy precipitation. In this study, a recently developed neighborhood in Gresham, Oregon hosts a comparison of various GSI projects on runoff dynamics. The study site includes dispersed GSI (rain gardens, retention chambers, green streets) and centralized GSI (bioswales, detention ponds, detention pipes). For the 2017-2018 water year, hourly rainfall and observed discharge data is used to calibrate the EPA's Stormwater Management Model to simulate rainfall-runoff dynamics, achieving a Nash-Sutcliffe efficiency of 0.75 and Probability Bias statistic of 3.3%. A …

From The Studio To The Street: Cultivating Democratic Norms In Uganda, Lee Shaker, Paul Falzone, Paul Sparks, Ruth Kugumikiriza

Communication Faculty Publications and Presentations

Communication interventions can make valuable contributions to the democratic development of citizens. This article reports on a nongovernmental organization’s (NGO’s) effort to leverage a television rap news program in Uganda to strengthen viewers’ democratic norms. Two different approaches addressing government failures and malfeasance are tested with an experiment conducted in six villages outside of Kampala. Results indicate that soft news segments can influence viewers’ perceived democratic norms and shape downstream behaviors as well. Beneficial effects were strongest when participants were exposed to stories that featured relatable citizens demonstrating desirable democratic attitudes and behaviors. Treatment effects were most pronounced among less …

Entre las directoras españolas más internacionales se destaca Coixet. Sus largometrajes, spots publicitarios, documentales y cortos evidencian un arte cinematográfico que apuesta por destacar la esencia universal del individuo en un marco deconstructivo sin contextos nacionales ni parámetros temporales. Los títulos y textos de sus obras nos hacen reflexionar en el poder de la imagen como vehículo artístico de compromiso social y visual. Ver sus creaciones es una sinestesia: el discurso fílmico conmueve más allá del plano visual-auditivo, haciendo que la imagen despierte sentidos como el gusto, el tacto y el olfato. Esta ponencia se centrará en decodificar su trayectoria …

To Copy, To Impress, To Distribute: The Start Of European Printing, Bennett Gilbert

University Studies Faculty Publications and Presentations

In order to distribute our thoughts and feelings, we must make intelligible and distributable copies of them. From approximately 1375 to 1450, certain Europeans started fully mechanized replication of texts and images, based on predecessor “smaller” technologies. What they started became the most powerful means for the distribution, storage, and retrieval of knowledge in history, up until the invention of digital means. We have scant information about the initiation of print technologies in the period up to Gutenberg, and the picture of Gutenberg that we have has become a great deal more complicated than hitherto. There has not been, however, …

Raven’S Work In Tlingit Ethno-Geography, Thomas F. Thornton, Douglas Deur, Bert Adams

This is a chapter in Language and Toponymy in Alaska and Beyond: Papers in Honor of James Kari.

Book description:
It is difficult to imagine place names research in Alaska without the work of James Kari. Through his tireless field work and advocacy, Dr. Kari has collaborated with speakers of all of Alaska’s Dene languages to help build a comprehensive record of Dene geographic knowledge. When Jim came to Alaska in 1972, the documentation of Dene languages was fragmentary at best, and the only records of Native place names were those found inaccurately spelled on maps and gazetteers. Now …

Reorientations; Or, An Indigenous Feminist Reflection On The Anthropocene, Kali Simmons

Indigenous Nations Studies Faculty Publications and Presentations

In lieu of an abstract, here is a brief excerpt of the content:

Destruction of homelands. Loss of kinship species. Exposure to deadly contaminants. Mass extinction. Transformed lifeways. In the face of these radical changes, a question lingers: How long will life be possible? Recently the academy has also felt the urgency of these environmental problems and proposed to address them within the framework of the term "the Anthropocene." Indigenous studies has offered various responses to the Anthropocene, some arguing that it has utility in framing the violence of colonialism and others critiquing the limitations and assumptions behind the "anthropos" …

Changes In Farmland Ownership In Oregon, Usa, Megan Horst

Urban Studies and Planning Faculty Publications and Presentations

The ownership of agricultural land has important implications for food systems, the environment, farmer livelihoods, and rural economies, communities, and landscapes. This article examines the changing ownership of agricultural lands in the United States, specifically focusing on Oregon, a state with a history of family farm ownership. I first review historical and recent trends in farmland ownership, including private enclosure, consolidation, investor purchase, development, and rising farmland prices. Next, I examine the county records for all Oregon farm properties that sold between 2010 and 2015. I provide summary statistics about the volume and pace of transactions, price per acre, and …
