Rearrangement Of The Rna Polymerase Subunit H And The Lower Jaw In Archaeal Elongation Complexes, Sebastian Grünberg, Christoph Reich, Mirijam E. Zeller, Michael S. Bartlett, Michael Thomm

Biology Faculty Publications and Presentations

The lower jaws of archaeal RNA polymerase and eukaryotic RNA polymerase II include orthologous subunits H and Rpb5, respectively. The tertiary structure of H is very similar to the structure of the C-terminal domain of Rpb5, and both subunits are proximal to downstream DNA in pre-initiation complexes. Analyses of reconstituted euryarchaeal polymerase lacking subunit H revealed that H is important for open complex formation and initial transcription. Eukaryotic Rpb5 rescues activity of the ΔH enzyme indicating a strong conservation of function for this subunit from archaea to eukaryotes. Photochemical cross-linking in elongation complexes revealed a striking structural rearrangement of RNA …

Solid State And Solution Dynamics Of Pyridine Based Tetraaza- Macrocyclic Lanthanide Chelates Possessing Phosphonate Ligating Functionality (Ln-Pctmb): Effect On Relaxometry And Optical Properties, Garry Kiefer, Mark Woods

Chemistry Faculty Publications and Presentations

The macrocyclic ligand 3,6,9-tris(methylenebutyl phosphonic acid)-3,6,9−15-tetraazabicyclo [9.3.1]pentadeca-1(15),11,13-triene (PCTMB) was synthesized and complexes of Eu³⁺, Tb³⁺, and Gd³⁺ studied by X-ray crystallography, luminescence, and relaxometry. In the crystal these complexes are dimeric and possess 8-coordinate Ln³⁺ centers that are linked by bridging phosphonates. The rigidity introduced by the pyridyl nucleus forces the EuPCTMB and TbPCTMB to adopt a twisted snub disphenoid (TSD) coordination geometry. Examination of the ⁵D₀ → ⁷F₀ luminescent transition of EuPCTMB in the solid state confirmed the existence of a single distinct Eu³⁺ coordination environment, whereas two …

Working Paper No. 62, Uses Of Abduction In Economic Science, Daniel Urban

Working Papers in Economics

This inquiry considers the meaning of abduction and its uses in Economic Science. Abductive logic is discussed at some length, in order to clarify how it is used in this inquiry. In addition, abduction is traced from its appearances in the writings of pragmatist philosopher Charles Sanders Peirce and how its meaning is later carried on in Thorstein Veblen’s Institutional Economics. Peirce’s influence proves foundational for Veblen’s contributions, as well as for the writings of John Roger Commons. My research suggests that after Commons, Peirce’s influence in economics wanes. Additionally, the use of retroduction in critical realism provides a contemporary …

Governance In Motion: Service Provision And Child Welfare Outcomes In A Performance-Based, Managed Care Contracting Environment, Bowen Mcbeath, William Meezan

School of Social Work Faculty Publications and Presentations

Examining the linkage between service provision and client outcomes is important in performance-based human service environments. Since most performance initiatives reward agencies for improving client outcomes rather than providing specific services, managers may have incentives to streamline workers’ efforts and reduce resources devoted to services considered nonessential. This article uses data from a performance-based child welfare initiative to examine the relationship between child permanency outcomes, the services provided by caseworkers, and the environment surrounding frontline service provision. Findings indicate that greater service efforts are required to reunify children with parents than to reach other outcomes, including adoption and placement with …

The loss occurred at both the elementary and high school levels, with decreases of 88 students (1.5 percent) in …

How Do You Say No?, Emily Ford

Library Faculty and Staff Publications and Presentations

The article discusses ways on how to say a "no." It states that a person's ability to say "no" to taking a new project at work or another appointment affects the mental wellness and healthy work or life balance. William Ury, author of the book "The Power of a Positive No" argues that positive "no" affirms an individual's values and sends clear communication with others. It also provides various experiences of the other workers of how they approach in saying "no."

The Distribution And Reproductive Success Of The Western Snowy Plover Along The Oregon Coast - 2009, David J. Lauten, Kathleen J. Castelein, J. Daniel Farrar, Hendrik G. Herlyn, Eleanor P. Gaines

Institute for Natural Resources Publications

From 3 April – 23 September 2009 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius alexandrinus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, New River, and Floras Lake. Our objectives for the Oregon coastal population in 2009 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue selective use of mini-exclosures (MEs) to protect nests …

Citizens’ Local Political Knowledge And The Role Of Media Access, Lee Shaker

Communication Faculty Publications and Presentations

Locally based media institutions that have been at the core of citizens' media environments for generations are facing an onslaught of new competition from new media. The twin goals of this article are to expand our understanding of the distribution of local political knowledge in general and to specifically examine the relevance of media access. The article suggests that media access does bear upon levels of local political knowledge and confirms that citizens who are knowledgeable about local politics do not mirror the profile of those who are knowledgeable about national politics.

Gain Guiding In Large-Core Bragg Fibers, Xianyu Ao, Tsing-Hua Her, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

We theoretically analyze gain guiding in large-core Bragg fibers, to be used for large-mode-area laser amplifiers with single-transverse-mode operation. The signal is gain-guided in a low-index core, whereas the pump is guided by the photonic bandgap of the Bragg cladding to achieve good confinement. The high-index layers in the Bragg cladding are half-wave thick at the signal wavelength in order to eliminate Bragg reflection, reducing the Bragg fiber effectively to a step-index fiber for gain guiding.

What Makes Developing Asia Resilient In A Financially Globalized World?, Hiro Ito, Juthathip Jongwanich, Akiko Terada-Hagiwara

Economics Faculty Publications and Presentations

The pullbacks of capital inflows to developing Asia following the onset of the global financial crisis in 2008 have brought renewed attention to the role and benefits of financial globalization. A number of notable distinctions between the current global crisis and the Asian financial crisis have become evident. Solid domestic institutions, especially in the financial sector; swift policy responses; and a sound macroeconomic environment with adequate reserves have helped the region to manage well the adverse impacts of the global crisis. Empirical analysis examining the link between capital account openness and output volatility reveals that a developing country with a …

Development Of A Multi-Class Bicyclist Route Choice Model Using Revealed Preference Data, Joseph Broach, John Gliebe, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Existing regional travel forecasting systems are not typically set up to forecast usage of bicycle infrastructure and are insensitive to bicyclists' route preferences in general. We collected revealed preference, GPS data on 162 bicyclists over the course of several days and coded the resulting trips to a highly detailed bicycle network model. We then use these data to estimate bicyclist route choice models. As part of this research, we developed a sophisticated choice set generation algorithm based on multiple permutations of labeled path attributes, which seems to out-perform comparable implementations of other route choice set generation algorithms. The model was …

Metaphors In Conversational Context: Toward A Connectivity Theory Of Metaphor Interpretation, L. David Ritchie

Communication Faculty Publications and Presentations

The model proposed in this article merges the cognitive and social elements of metaphor use and interpretation in the cognitive representation of mutual cognitive environment (Sperber & Wilson, 1986/1995) or common ground (Clark, 1996). The proposed principle of metaphor interpretation is based on the interaction of both vehicle and topic with the common ground. Because common ground is inherently problematic, it is rarely accurate to discuss "the meaning of" a metaphor, as if metaphors must have a single well-specified meaning. Each metaphor is interpreted in the particular communicative context in which it is encountered, and individual interpretations will not necessarily …

Computer-Aided Assessment Of Diagnostic Images For Epidemiological Research, Alison G. Abraham, Donald D. Duncan, Stephen J. Gange, Sheila West

Electrical and Computer Engineering Faculty Publications and Presentations

Background: Diagnostic images are often assessed for clinical outcomes using subjective methods, which are limited by the skill of the reviewer. Computer-aided diagnosis (CAD) algorithms that assist reviewers in their decisions concerning outcomes have been developed to increase sensitivity and specificity in the clinical setting. However, these systems have not been well utilized in research settings to improve the measurement of clinical endpoints. Reductions in bias through their use could have important implications for etiologic research. Methods: Using the example of cortical cataract detection, we developed an algorithm for assisting a reviewer in evaluating digital images for the presence and …

Co-Evolution Of Transportation And Land Use: Modeling Historical Dependencies In Land Use And Decision-Making, Lei Zhang, Wei Zu, Mingxin Li

TREC Final Reports

The interaction between land use and transportation has long been the central issue in urban and regional planning. Models of such interactions provide vital information to support many public policy decisions, such as land supply, infrastructure provision, and growth management. Both the transportation and land use systems exhibit historical dependencies in policy decisions. For instance, the expansion of a roadway today will change travel demand patterns, and make certain other roads more or less likely to be expanded in the future. A specific land supply decision made at one point in time, by changing the relative attractiveness of other areas …

Probabilistic Tsunami Hazard Assessment At Seaside, Oregon, For Near- And Far-Field Seismic Sources, Frank González, Eric L. Geist, Bruce Jaffe, Utku Kânoğlu, Harold O. Mofjeld, Costas Synolakis, Vasily V. Titov, Diego Rodriguez Arcas, Douglas Bellomo, David Carlton, Thomas Horning, Jeff Johnson, Jean Newman, Thomas Parsons, Robert Peters, Curt D. Peterson, George Priest, Angie Venturato, Joseph Weber, Florence L. Wong, Ahmet Yalçıner

Geology Faculty Publications and Presentations

The first probabilistic tsunami flooding maps have been developed. The methodology, called probabilistic tsunami hazard assessment (PTHA), integrates tsunami inundation modeling with methods of probabilistic seismic hazard assessment (PSHA). Application of the methodology to Seaside, Oregon, has yielded estimates of the spatial distribution of 100- and 500-year maximum tsunami amplitudes, i.e., amplitudes with 1% and 0.2% annual probability of exceedance. The 100-year tsunami is generated most frequently by far-field sources in the Alaska-Aleutian Subduction Zone and is characterized by maximum amplitudes that do not exceed 4 m, with an inland extent of less than 500 m. In contrast, the 500-year …
