Volcanic Glass As A Proxy For Paleotopography Suggests New Features In Late-Miocene Oregon, Julian Cohen, John Bershaw, Richard Hugo May 2024

Volcanic Glass As A Proxy For Paleotopography Suggests New Features In Late-Miocene Oregon, Julian Cohen, John Bershaw, Richard Hugo

Geology Faculty Publications and Presentations

Volcanic glass has been used extensively as a paleoaltimeter. Deuterium (2H) concentrations in glass have been found to be stable over geologic timescales, making δ2H (also known as δD) a reliable proxy for ancient water chemistry. However, continued work revolves around better understanding how different factors affect preserved water in volcanic ash. Here, we analyze δD in the Rattlesnake Tuff (RST), a widespread ca. 7 Ma ash-flow tuff, and create a paleoisoscape to assess variations in δD across Oregon during that time. To this end, 16 ash samples were collected across central and eastern Oregon from …


Wait, You Don’T Have An Open Access Policy?: Passing An Oa Policy In 2021, Miriam Rigby, Franny Gaede, Catherine Flynn-Purvis, David Condon Mar 2022

Wait, You Don’T Have An Open Access Policy?: Passing An Oa Policy In 2021, Miriam Rigby, Franny Gaede, Catherine Flynn-Purvis, David Condon

Online Northwest

Twenty years after passing a resolution supporting open access, the University of Oregon Faculty Senate passed their first comprehensive Open Scholarship Policy. Library personnel and faculty champions collaborated in this enormous effort over two years. This demanded the recognition of new models of scholarship and the development of new workflows leveraging the institutional repository and other tools. Given faculty hesitancy and uncertainty over mandates and enforcement, significant coalition-building was difficult in the time of COVID-19, but necessary to achieve consensus. We will share our strategies for success and suggestions for how they may be replicated.


Does Restoration Of Urban Riparian Zones Impact Stream Water Quality In Portland, Oregon, Ash Ivanov Mar 2022

Does Restoration Of Urban Riparian Zones Impact Stream Water Quality In Portland, Oregon, Ash Ivanov

University Honors Theses

Riparian zones influence urban stream quality through factors such as shading the stream, adding nutrients through leaf litter, stabilizing the stream banks to reduce turbidity, and filtering toxins out of the water. Riparian restoration often involves changing plant assemblage to be more diverse and include primarily native species instead of non-native, improving connection to the stream through changing stream morphology, improving species habitat, and reducing pollution. The goal of this study was to determine if urban riparian restoration projects in the region were successful, and if not, why that may be the case. The study was performed in the Portland, …

Sustaining Institutional Repositories: Breaking The Mold To Add Value, Karen Bjork, Ryan Otto, Rebel Cummings-Sauls

Library Faculty Publications and Presentations

Librarians at Kansas State University and Portland State University recognized a need to document and showcase a more complete view of the digital scholarship from their institution’s faculty, staff, and students; giving each library the ability to elevate the academic research and creative output being produced by their community. The proposed expansion of representation would be accomplished through the addition of metadata only (non full text) records in their institutional repositories (IR), the inclusion of which may run counter to the archetype of open access (OA) IR. The need to provide a more comprehensive view of scholarly activity has been …

A Virtual Lock-In Amplifier, Spectrum Analyzer, Impedance Meter And Semiconductor Analyzer Implemented On An Sr7265 Hardware Target, Jianghua Bai, John L. Freeouf, Andres H. La Rosa

Physics Faculty Publications and Presentations

Lock-in amplifiers are used to detect and measure very small AC signals down to the range of nVs. Accurate measurements may be made even when the small signals are buried by noise sources thousands of times larger. With the digital signal processing (DSP) technology involved in modern instrumentation, a lock-in amplifier is more versatile than sensing and recover small signals. Combining the virtual instrumentation technology, we reorganize the functional blocks of a programmable lock-in amplifier and build it as a virtual spectrum analyzer, virtual impedance meter, virtual network analyzer, virtual semiconductor parameter analyzer, signal generator, etc. A 4 layer model …

Sails, Take 2: An Exploration Of The “Build Your Own Test” Standardized Il Testing Option For Canadian Institutions, Rumi Y. Graham, Nicole Eva, Sandra Cowan

Communications in Information Literacy

Several standardized and validated information literacy (IL) tests have been developed for use in U.S. post-secondary contexts, but fewer choices exist for schools outside of the U.S. In an earlier study (Cowan, Graham, & Eva, 2016) the authors explored IL testing at a Canadian university using the international version of the SAILS Cohort test. This article describes a second study that used the Build Your Own Test (BYOT)—a customizable version of the SAILS Individual Scores test—to evaluate undergraduate students’ IL learning. Pros and cons of using the Cohort and BYOT versions of SAILS are discussed, with the aim of providing …

This is typically at vehicle launch from standstill, at very low speeds, and during energy regeneration at lower speeds and approaching standstill. The KersTech solution is a breakthrough technology allowing supplement of the electric drive with a hydraulic drive, active in lower speeds ranges, dropping out as the electric motor takes over in its higher efficiency range of operation. The report consists of four parts. Part I presents …


Adoption And Child Trafficking: Structural Violence In The International Adoption System, Vanessa Virgiel Jan 2014

Adoption And Child Trafficking: Structural Violence In The International Adoption System, Vanessa Virgiel

University Honors Theses

In the United States there exists as part of the institution of international adoption a hegemony of “saving” orphans from developing or economically devastated nations. This hegemony is a factor contributing to an adoption “market” in orphans, leading to incidences of the trafficking of children as part of the intercountry adoption system. This study's purposes are thus twofold. First it is a preliminary attempt within the academic realm to determine the emergence of this hegemony by delineating the US history of intercountry adoption from its origins in the mid-1940s as a response to humanitarian crises, to its current status as …


The Value Of Well-Being: Advancing Urban Blue Infrastructure With Holistic Metrics, Lisa Marie White Jan 2014

The Value Of Well-Being: Advancing Urban Blue Infrastructure With Holistic Metrics, Lisa Marie White

University Honors Theses

The design of urban infrastructure has emerging, documented impacts on the environment, local economy, and public well-being, yet conventional design and policy goals fail to account for these emergent properties. These impacts also lack consistent quantifiable metrics and classification in the realm of city planning. Without adequately holistic cost-benefit analyses, the true value of infrastructure projects fails to be ascertained, preventing consideration of design that provides additional benefits not yet incorporated into city policy and metrics. With more people living in cities than ever before, the built environment of cities has become an increasingly important area of study, and the …

The Changing Roles Of Repositories: Where We Are And Where We Are Headed, Karen Bjork, David Isaak, Kay Vyhnanek

Library Faculty Publications and Presentations

This presentation examines the past, present, and future role of institutional repositories (IRs). IRs rapidly rose to prominence in libraries, but failed to live up to the promise of transforming scholarly communication. A decade since the debut of DSpace, IRs today look very different in their content and services. We will present the results of an in‐depth survey of repository managers. The role of IRs is now evolving to include support for data curation, e‐research, and scholarly networks. The session concluded with a discussion of how repository managers can better network and share expertise. Files ending in .csv are plain-text, …


Research Guide Technologies, Meredith G. Farkas Jan 2012

Research Guide Technologies, Meredith G. Farkas

Library Faculty Publications and Presentations

Research guides (also known as subject guides, course guides, or pathfinders) provide targeted information on a particular topic to support student or faculty research in that area. Similar instructional tools have been around since before the birth of the web, but are now almost exclusively provided by libraries online as part of the library’s web presence. Research guide software enables librarians without web design skills to quickly and easily create and update web content. The technologies for creating research guides run the gamut from proprietary and open source software specifically designed for creating guides to open source and third-party-hosted applications …
