Cul3 Ubiquitin Ligase And Ctb73 Protein Interactions, Lacey Royer

University Honors Theses

Ubiquitination is a fundamental biochemical process, which controls numerous aspects of protein function, such as degradation, protein-protein interaction and sub cellular localization. Cullin 3 (Cul3) is a ubiquitin ligase that is fundamentally responsible for ubiquitination of proteins and plays a critical role in normal cellular processes. Cul3 has been shown to use substrate adaptors to facilitate the ubiquitination process and many of these substrate adaptors contain BTB domains among other protein-protein interacting domains. A novel BTB domain containing protein is Ctb73. Ctb73 has a BACK and Kelch domain along with a BTB domain. It has not been shown whether Ctb73 …

The Media’S Presentation Of The Second Chance Act: Funding For Reentry Following Prison, A Content Analysis, Ailene Joyce Farkac

University Honors Theses

The US prison system has multiplied by four since 1980; each year about 730,000 people enter state and federal prisons and 700,000 people exit. As a result of this expansion, there is a massive increase of formerly incarcerated people reentering local communities every year. Budget cuts in prison programs and in local government’s social services are causing these individuals to be less educated and less prepared for reintegration; communities are also ill prepared to absorb them. The Second Chance Act was signed into law by President Bush on April 9, 2008. It authorized a pool of about $393m (renewed in …

Endogenous Ros Levels In C. Elegans Under Exogenous Stress Support Revision Of Oxidative Stress Theory Of Life-History Tradeoffs, Samson W. Smith, Leigh C. Latta Iv, Dee R. Denver, Suzanne Estes

Biology Faculty Publications and Presentations

Background: The oxidative stress theory of life-history tradeoffs states that oxidative stress caused by damaging free radicals directly underpins tradeoffs between reproduction and longevity by altering the allocation of energetic resources between these tasks. We test this theory by characterizing the effects of exogenous oxidative insult and its interaction with thermal stress and diet quality on a suite of life-history traits and correlations in Caenorhabditis elegans nematodes. We also quantify demographic aging rates and endogenous reactive oxygen species (ROS) levels in live animals.

Results: Our findings indicate a tradeoff between investment in reproduction and antioxidant defense (somatic maintenance) consistent with …

Clean Water Grow: Go Or No Go?, Simon Ngawhika, Scott Marshall

Business Faculty Publications and Presentations

The $43 billion US wastewater treatment industry is a landscape in which the high costs of capital construction and the need for economies of scale feature prominently. The US Environmental Protection Agency estimates that between 2004 and 2024, over $200 billion will need to be spent upgrading and expanding America’s wastewater infrastructure.

One significant challenge in maintaining treatment infrastructure is the build-up of struvite. Struvite accumulates inside treatment facility pipe networks, reducing capacity and increasing operating and maintenance costs. But discharging the components of struvite – the nutrients nitrogen and phosphorous – into the environment also has negative consequences. Concentrated …

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 …

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 …

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 …

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.

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 …

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.

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 …

Giving Games The Old College Try, Amy R. Hofer

Library Faculty and Staff 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 …

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 …

This study looks at how place and local identity of Portland are described within music lyrics from Portland, Oregon popular indie-rock artists. Employing a constant comparative analysis on a set of 1,201 songs from 21 different popular Portland indie-rock artists, the themes of landscapes and climate were found to represent place, and themes of lifestyles and attitudes represented local identity. Reviewing the uncovered themes showed a strong connection between representations of place and local identity within lyrics and common stereotypes or understandings of the city of Portland and its indie-rock music scene. The results of this study illustrate how place …

Sexting Unleashed: The Social Phenomenon According To Youth Sexters, Jessica Marie Mcgraw

Dissertations and Theses

What is missing from academia and society at large is a more holistic picture of youth sexting. Not adequately understanding youth sexting has stunted previous attempts to effectively educate young people on its potential consequences. As such, the social and legal consequences of sexting gone viral have negatively impacted countless individuals. This study offers a preliminary glimpse of the sexting phenomenon by highlighting the experiences of 20 young people. I explore emergent themes regarding the nature of youth sexting as well as the interrelations amongst privacy, relationships, and sexting. Two distinct forms of sexting emerged from participant narratives, opening the …

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).

Novel Thermophilic Bacteria Isolated From Marine Hydrothermal Vents, Christine Demko Sislak

As part of a large study aimed at searching for patterns of diversity in the genus Persephonella along the north to south geochemical gradient of the ELSC, ten novel strains of Alphaproteobacteria were isolated unexpectedly. Using defined media under microaerophilic conditions to enrich for Persephonella from chimney samples collected at the seven vent fields on the ELSC and the dilution to extinction by serial dilution method to purify cultures, a total of ten strains belonging to the Alphaproteobacteria were isolated. Two of these isolates, designate MN-5 and TC-2 were chosen for further characterization and are proposed as two new species …

Who Owns This Body? Enslaved Women's Claim On Themselves, Loucynda Elayne Sandeen

Dissertations and Theses

During the antebellum period of U.S. slavery (1830-1861), many people claimed ownership of the enslaved woman's body, both legally and figuratively. The assumption that they were merely property, however, belies the unstable, shifting truths about bodily ownership. This thesis inquires into the gendered specifics and ambiguities of the law, the body, and women under slavery. By examining the particular bodily regulation and exploitation of enslaved women, especially around their reproductive labor, I suggest that new operations of oppression and also of resistance come into focus.

The legal structure recognized enslaved women in the interest of owners, and this limitation was …
