Partitioning The Fitness Components Of Rna Populations Evolving In Vitro, Carolina Diaz Arenas, Niles Lehman

Chemistry Faculty Publications and Presentations

All individuals in an evolving population compete for resources, and their performance is measured by a fitness metric. The performance of the individuals is relative to their abilities and to the biotic surroundings – the conditions under which they are competing – and involves many components. Molecules evolving in a test tube can also face complex environments and dynamics, and their fitnessmeasurements should reflect the complexity of various contributing factors as well. Here, the fitnesses of a set of ligase ribozymes evolved by the continuous in vitroevolution system were measured. During these evolution cycles there are three different catalytic …

The Uncertain Future Of A 'New Type' Of Us-China Relationship　不透明な「新型」米中関係の未来, Mel Gurtov

Political Science Faculty Publications and Presentations

President Xi Jinping's call for a "new type of great-power relationship" in meetings in 2013 with President Obama raises important questions about the future of US-China relations. On the surface, it appeared that the two leaders were on the same page. At the June summit, Obama agreed with Xi that "working together cooperatively" and bringing US-China relations "to a new level" were sound ideas. When the G-20 countries convened at St. Petersburg in September, Obama said of Xi’s proposed new model: "we agreed to continue to build a new model of great power relations based on practical cooperation and constructively …

Info Lit 2.0 Or Deja Vu?, Patricia Anne Iannuzzi

Communications in Information Literacy

In 1999, ACRL convened a national task force to draft Information Literacy Competency Standards for Higher Education. ACRL has recently launched a revision to those standards. The original standards were influential because they helped advance a national need in higher education at the time: a shift to outcomes based learning. Fourteen years later, information literacy stands alongside oral and written communication, critical thinking and ethical reasoning as learning outcomes broadly acknowledged as needing to be integrated, with disciplinary content, into the curriculum. This author believes that, in contrast to the first process, the current recommendations for revision are focused on …

Minding The Gaps: Exploring The Space Between Vision And Assessment In Information Literacy Work, Heidi L.M. Jacobs

Communications in Information Literacy

The current "ACRL Information Literacy Competency Standard Review Task Force" presents information literacy practitioners with an engaging intellectual endeavor: how might these standards be revised, rethought, re-envisioned? Regardless of what the review yields, the process is an excellent opportunity for us to think broadly and creatively about the Standards and to remember that they are not a fixed set of rules but a malleable and evolving document. Asking questions about the practical, pedagogical, and theoretical implications of the Standards and considering alternative approaches will yield engaging, fruitful, and necessary conversations not only about the teaching of information literacy but about …

The New Acrl Information Literacy Competency Standards: Revising Reception, Benjamin R. Harris

Communications in Information Literacy

The publication of educational standards inspires a variety of responses---from wholesale acceptance and deployment to criticism and blame. The author of this paper contends that the revision of the ACRL's Information Literacy Competency Standards for Higher Education must be accompanied by a critical, conscious, and conscientious reception by librarians and information literacy advocates.

A Reconsideration Of Information Literacy, Stanley J. Wilder

Communications in Information Literacy

This article is a reflection on the author's 2005 Chronicle of Higher Education article "Information Literacy Makes All the Wrong Assumptions." In it, the author argues that while library instruction is properly grounded in disciplinary norms, information literacy serves a vital institutional obligation as a means of assessing student learning. The content of library instruction thus serves the University's "vertical" disciplinary agendas, while information literacy serves its "horizontal" institution-wide agenda.

Proposing A Metaliteracy Model To Redefine Information Literacy, Trudi E. Jacobson, Thomas P. Mackey

Communications in Information Literacy

Metaliteracy is envisioned as a comprehensive model for information literacy to advance critical thinking and reflection in social media, open learning settings, and online communities. At this critical time in higher education, an expansion of the original definition of information literacy is required to include the interactive production and sharing of original and repurposed digital materials. Metaliteracy provides an overarching and unifying framework that builds on the core information literacy competencies while addressing the revolutionary changes in how learners communicate, create, and distribute information in participatory environments. Central to the metaliteracy model is a metacognitive component that encourages learners to …

Rethinking The 2000 Acrl Standards: Some Things To Consider, Carol C. Kuhlthau

Communications in Information Literacy

I propose three "rethinks" to consider in recasting the ACRL Standards for information literacy for the coming decades. First, rethink the concept of information need. Second, rethink the notion that information literacy is composed of a set of abilities for "extracting information." Third, rethink the holistic process of learning from a variety of sources of information that is central to information literacy. The necessity for these "rethinks" are grounded in my extensive studies of students' experience in the information search process that reveal an evolving, dynamic, holistic process incorporating a series of feelings (affective), thoughts (cognitive) and actions (physical) as …

Refreshing Information Literacy: Learning From Recent British Information Literacy Models, Justine Martin

Communications in Information Literacy

Models play an important role in helping practitioners implement and promote information literacy. Over time models can lose relevance with the advances in technology, society, and learning theory. Practitioners and scholars often call for adaptations or transformations of these frameworks to articulate the learning needs in information literacy development. This study analyzes four recently published models from the United Kingdom. The initial findings were presented in a report for an ACRL taskforce reviewing the Information Literacy Competency Standards for Higher Education. This article presents complementary, yet distinct findings from the same dataset that focus on reoccurring themes for information literacy …

Transforming Information Literacy In The Sciences Through The Lens Of E-Science, Elizabeth Berman

Communications in Information Literacy

In 2011, the ACRL Science & Technology Section (STS) completed its five-year review of the Information Literacy Standards for Science and Engineering/Technology. Predicated by the evolving nature of scholarship and research in the sciences, the reviewing task force strongly recommended that the standards be revised. This paper considers the broad recommendations of the task force, using the framework of e-Science – team-based, data-driven science – to address areas of necessary transformation in information literacy: an advanced team-based model that crosses disciplinary boundaries; a recognition that individuals and groups not only consume information, but also produce it; and stronger interplay between …

How Aasl Learning Standards Inform Acrl Information Literacy Standards, Lesley S. J. Farmer

Communications in Information Literacy

ACRL and other academic librarians are currently re-examining the tough questions of learning, literacy, and education -- and the librarians' role in addressing these issues. They can use AASL's learning standards as one springboard for thought, particularly in terms of articulating learning. The result is a developmentally appropriate set of standards that reflects lifelong engagement with, and creation of, recorded information.

Information Literacy And Digital Literacy: Competing Or Complementary?, Rosanne Marie Cordell

Communications in Information Literacy

Digital Literacy is a more recent term than Information Literacy and is used for multiple categories of library users in multiple types of libraries. Determining the relationship between Information Literacy and Digital Literacy is essential before revision of the Information Literacy Standards can proceed.

Time For A Paradigm Shift: The New Acrl Information Literacy Competency Standards For Higher Education, Marcus Banks

Communications in Information Literacy

Academic librarians should expand our understanding of what counts as an authoritative resource, and be unafraid to challenge long-established wisdom in this domain. Wikipedia is far from perfect, but neither is the Encyclopedia Britannica. Wikipedia is updated daily, while the Britannica is no longer printed. If we cling to the Britannica as a symbol of authoritativeness, we will become obsolete ourselves. One way to prevent this fate is to reframe our collective thinking. In 2014 the Association of College and Research Libraries (ACRL) will issue a revised version of the Information Literacy Competency Standards for Higher Education. The task force …

Giving Games The Old College Try, Amy R. Hofer

Library Faculty Publications and Presentations

Based on evidence that games might help students get more engaged in my online class, I decided to overcome my skepticism and road-test two information literacy games. First I tried BiblioBouts, which uses the online citation management tool Zotero to integrate gaming into a research paper assignment that is already part of the course syllabus. Students have to set up Zotero accounts and log into the game’s online platform to play and see their scoreboard; the technology requirements were too much for my class and the experiment didn’t feel successful. The following year I tried a comparatively low-tech game that …

Battery Energy Storage Systems To Mitigate The Variability Of Photovoltaic Power Generation, Heath Alan Gurganus

Dissertations and Theses

Methods of generating renewable energy such as through solar photovoltaic (PV) cells and wind turbines offer great promise in terms of a reduced carbon footprint and overall impact on the environment. However, these methods also share the attribute of being highly stochastic, meaning they are variable in such a way that is difficult to forecast with sufficient accuracy. While solar power currently constitutes a small amount of generating potential in most regions, the cost of photovoltaics continues to decline and a trend has emerged to build larger PV plants than was once feasible. This has brought the matter of increased …

The Dynamics Of Creating Strong Democracy In Portland, Oregon : 1974 To 2013, Paul Roland Leistner

Dissertations and Theses

Communities across the United States are experiencing a "civic revival" that is reconnecting community members with local decision-making and civic life in their communities. Since the 1980s, academic researchers and local governance reformers have advocated for a shift away from the traditional top-down, expert-driven approach to governance and toward a governance model in which government leaders and staff and community members work as partners to shape the community and make local decisions. Portland, Oregon, since the 1970s, has been known nationally and internationally as a city with a tradition of strong community involvement. Portland's successes and failures offer a valuable …

Modeling Fecal Bacteria In Oregon Coastal Streams Using Spatially Explicit Watershed Characteristics, Paul Bryce Pettus

Dissertations and Theses

Pathogens, such as Escherichia coli and fecal coliforms, are causing the majority of water quality impairments in U.S., making up ~87% of this grouping's violations. Predicting and characterizing source, transport processes, and microbial survival rates is extremely challenging, due to the dynamic nature of each of these components. This research built upon current analytical methods that are used as exploratory tools to predict pathogen indicator counts across regional scales. Using a series of non-parametric methodologies, with spatially explicit predictors, 6657 samples from non-estuarine lotic streams were analyzed to make generalized predictions of regional water quality. 532 frequently sampled sites in …

Direct Coupling Of Photonic Modes And Surface Plasmon Polaritons Observed In 2-Photon Peem, Robert Campbell Word, Joseph Fitzgerald, Rolf Könenkamp

Physics Faculty Publications and Presentations

We report the direct microscopic observation of optical energy transfer from guided photonic modes in an indium tin oxide (ITO) thin film to surface plasmon polaritons (SPP) at the surfaces of a single crystalline gold platelet. The photonic and SPP modes appear as an interference pattern in the photoelectron emission yield across the surface of the specimen. We explore the momentum match between the photonic and SPP modes in terms of simple waveguide theory and the three-layer slab model for bound SPP modes of thin metal films. We show that because the gold is thin (30- 40 nm), two SPP …

Working Paper No. 32, Canada And The United States: A Comparison Of Their Philosophical Bases, Lorraine M. Hutton

Working Papers in Economics

Americans and Canadians seem similar in many ways; however, their dissimilar historical experiences have shaped very different attitudes and philosophies that underpin their institutions. Canadians promote equality and collective responsibility under a restrained, parliamentary state, whilst the Americans stress self-reliance, individualism and freedom. Canadians embraced the hierarchical structure of the British and French Empires and Americans revolted against all ties to it. What appear to be minor distinctions between the two countries and cultures are actually fundamental philosophies rooted in the past.

Scenario Development And Analysis Of Freshwater Ecosystem Services Under Land Cover And Climate Change In The Tualatin And Yamhill River Basins, Oregon, Robert Wesley Hoyer

Dissertations and Theses

Humans make decisions within ecosystems to enhance their well-being, but choices can lead to unintended consequences. The ecosystem services (ES) approach supports decision-making that considers all environmental goods and services. Many challenges remain in the implementation of the ES approach like how specific ES vary through space and time. We address this research problem using the Tualatin and Yamhill river basins in northwestern Oregon as a study area. Freshwater ES are quantified and mapped with the spatially-explicit ES modeling tool, Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST). In chapter II, we develop a simple urban land cover change modeling …

An Investigation Into Instructional Support For Data Analysis In High School Science Inquiry, Anika Rae Baker-Lawrence

Dissertations and Theses

The implementation of scientific inquiry in the high school classroom has proven to be not only relevant and exploratory, but challenging and engaging as well. This style of curriculum design has been recognized as a primary means of achieving the goals and objectives set by the National Resource Council (NRC, 1996). While much research has shown that science inquiry helps students to gain understanding of content knowledge, little research has been conducted to assess gains in higher order thinking skills, specifically those related to data analysis (Anderson, 2002; Germann and Aram, 1996; Hofstein, Navon, Kipnis, and Mamlok-Naaman, 2005; Miner, Levy, …

Enhanced Sonar Array Target Localization Using Time-Frequency Interference Phenomena, Jordan Almon Shibley

Dissertations and Theses

The ability of traditional active sonar processing methods to detect targets is often limited by clutter and reverberation from ocean environments. Similarly, multipath arrivals from radiating sources such as ships and submarines are received at sensors in passive sonar systems. Reverberation and multipath signals introduce constructive and destructive interference patterns in received spectrograms in both active and passive sonar applications that vary with target range and frequency. The characterization and use of interference phenomena can provide insights into environmental parameters and target movement in conjunction with standard processing methods including spectrograms and array beamforming.

This thesis focuses on utilizing the …

Identification And Characterization Of Fine Particulate Matter Hot Spots On An Urban Arterial Corridor Integrating Probe Vehicle, Traffic And Land Use Data, Katherine Eleanor Bell

Dissertations and Theses

The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM[subscript 2.5]) hot spot locations on urban arterial corridors. In addition, a preliminary analysis is conducted to consider volatile organic compound (VOC) hot spot locations. A pollutant hot spot is defined as a location on a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when compared to all locations along the corridor. In order to collect data for this study, an electric vehicle was equipped with …

Coordinating Job Release Dates With Workdays: A Job Shop Application To Utilities Field Service Scheduling, Ryan Lawrence Pelkey

Dissertations and Theses

A local utility company processes a variety of jobs each day including meter reading, service shut-offs, emergency response, and customer service work. For the Company, a specific workflow begins with automated meter-reading (AMR) and ends with collections/service shut-offs (CSOs) for accounts with excessively late payments (AMR-CSO workflow). There are considerable and systemic sources of variability in both the workload and resource demands of the AMR-CSO workflow including order arrival, order release schedules, order batch-sizing and maintenance scheduling.

This project draws on theory from the job-shop problem to explore possible means to mitigate this variability. We hypothesized that controlling various forms …

Factors Influencing Youth Self-Perceptions Of Overweight And Obesity, Caitlin Helen Sommers

Dissertations and Theses

This study sought to examine whether participation in physical activity affects the ability to correctly classify body size, based on body mass index classifications. Secondarily, this study determined whether adolescents who incorrectly classified their body size overestimated or underestimated their size. Self-report data from the Youth Risk Behavior Surveillance Survey collected by the Centers for Disease Control and Prevention were analyzed. Logistic regression was performed to examine relationships between self-perception of body size and physical activity, television viewing time, computer/video game use, physical education class time, and extracurricular sports activities. Significance was set to p<0.05. Physical activity was the only statistically significant independent variable (p=0.058, OR = 1.060). Although physical activity was shown to be statistically significant, it did not appear to meaningfully increase the ability of youth to correctly classify body size. Secondary analysis showed that adolescents who incorrectly classified their body size were more likely to underestimate their body size. Females more frequently underestimated their body size (females=673; males=384).
