Committees In The Oregon State Legislature: Partisan, Distributive, Or Informational, Woodrow C. Moore

Dissertations and Theses

The study of legislative committees has overwhelmingly been focused on the Congressional level. This has left legislative committees at the state level largely unstudied. Committees in the Oregon State Legislature are an essential and powerful part of the policy making process and Oregon is unlike most other states in that bills cannot be amended on the floor. Using three theories regarding legislative committees -- the informational theory, distributive theory, and the partisan theory -- that were put forth by Krehbiel, Cox and McCubbins, and Weingast and Marshall, this paper will examine the Oregon State Legislature's committee system through a series …

Evaluating Militant Decision-Making With Information Science: The Irish Republican Movement During The "Troubles", Joshua C. Eastin, Emily Kalah Gade, Michael Gabbay

Political Science Faculty Publications and Presentations

Why do militant groups decide to escalate or deescalate their use of violence in conflict? Examining the case of the “Troubles” in Northern Ireland, we analyze groups that adopt violence as a political strategy and evaluate factors that influence its application. To do so, we adopt a novel empirical approach to the study of militant groups. Drawn from information science, this approach enables estimation of variable influence and uncertainty within structured case studies, and is thus ideal for topics such as militant decision-making where systematic data collection is difficult.

Tiny Drifters Amidst Global Change: Examining Environmental Drivers, Trophic Impacts, And Management Strategies Of Estuarine Plankton Communities In The Anthropocene, Taylor Nicole Dodrill

Dissertations and Theses

Plankton productivity supports estuarine food webs, and has been tied to the success of fisheries, macroinvertebrates, and cultured shellfish yields. Climate change and alterations to nutrient loads are thought to be influencing plankton assemblages, with toxin-producing harmful algal blooms (HABs) on the rise and nutritional quality of plankton declining globally. These shifts in plankton communities may contribute to low biomass yields and toxin-based closures of important fisheries. The objectives of this dissertation are to identify environmental drivers, trophic impacts, and management strategies to understand and respond to changing estuarine plankton communities. To address these objectives, I used a combination of …

Autonomy In The Spaces: Teacher Autonomy, Scripted Lessons, And The Changing Role Of Teachers, Madhu Narayanan, A. L. Shields, T. J. Delhagen

Educational Leadership and Policy Faculty Publications and Presentations

The work of teachers has historically been highly controlled, but one area teachers have been granted considerable autonomy is in instruction and planning. Teacher autonomy is a complex concept with important implications for both the quality of instruction and teacher persistence in the field. The rise of charter management organizations (CMOs) and the increasing use of scripted lesson plans (SLPs) have introduced new institutional arrangements with unknown impacts on teachers’ perceptions of autonomy. This mixed method study surveyed 155 teachers across all grade levels from CMOs, independent charter, and district schools, on their perceptions of autonomy related to lesson planning. …

The Discovery Of Diverse Picophytoplankton Populations In The Columbia And Willamette Rivers Using Flow Cytometry, Kylee M. Lamberson

Chemistry Undergraduate Departmental Honors Theses

As important primary producers, picophytoplankton determine the flow of carbon and energy in aquatic ecosystems. Picocyanobacteria are one picophytoplankton group known to be dominant in oceans and lakes, but they are still poorly understood in river systems. This project examined picophytoplankton communities in two distinct river systems: the Columbia and Willamette Rivers in Portland, Oregon. I aimed to characterize and quantify the picophytoplankton populations in the context of the environmental conditions of the two rivers. I used flow cytometry to detect cells based on their relative size and pigment fluorescence. I sampled nearly weekly for ten months to capture population …

Feasibility was mainly verified by the technical function of the intervention at Month 6. The …

Antibody Banding Patterns On The Enzyme-Linked Immunoelectrotransfer Blot (Eitb) Assay Clearly Discriminate Viable Cysticercosis In Naturally Infected Pigs, Gianfranco Arroyo, Andrés G. Lescano, Cesar M. Gavidia, Maria Teresa Lopez-Urbina, Miguel Ara-Gomez, Lucho Gomez-Puerta, Seth E. O’Neal, Multiple Additional Authors

OHSU-PSU School of Public Health Faculty Publications and Presentations

Enzyme-linked immunoelectrotransfer blot (EITB) detects antibodies against seven Taenia solium larvae antigens in three protein families (GP50, T24/42, and 8-kDa) with different structures and functions. EITB banding patterns against these antigens in pigs provide information about the course of infection and may discriminate viable cysticercosis. We analyzed the banding patterns and infection outcomes (presence of viable cysts, degenerated cysts, and any cysts) of 512 rural pigs. Banding patterns were grouped into homogenous classes using latent class analysis, and relationships with infection outcomes were assessed. Four classes were identified: 1 (n = 308, EITB-negative or positive for the GP50 family), 2 …

An Exploration Of Two Information Literacy Open Learning Object Repositories: Value, Content, And Engagement, Tiffanie Lynn Ford-Baxter

Communications in Information Literacy

Information literacy (IL) open learning object repositories (LORs) provide a space for librarians to find and exchange instruction resources and lessons. Given many librarians enter the workforce with little or no formal training or educational opportunities to learn about pedagogy, these repositories are indispensable resources to the Library and Information Science field. This study explored the contents of two popular IL LORs, Project Cora and the Association of College and Research Libraries Framework for Information Literacy Sandbox, to uncover how users engage with the resources and how the repositories differ. This study's findings suggest that while resources within the LORs …

Coastal Wetland Restoration Through The Lens Of Odum's Theory Of Ecosystem Development, Friedrich W. Keppeler, Annette S. Engel, Linda M. Hooper-Bùi, Paola C. López-Duarte, Charles W. Martin, Jill A. Olin, Katelyn J. Lamb, Michael J. Polito, Nancy N. Rabalais, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Advancing ecological restoration assessments requires a more detailed consideration of species interactions and ecosystem processes. Most restoration projects rely on a few metrics not always directly linked with ecological theory. Here, we used Odum's theory of ecosystem development to assess and compare the ecosystem structure and services of created marshes (4–6 years old) with preexisting, reference marshes in a brackish water region of the Mississippi River Delta. We built ecosystem models for created and reference marshes that integrated large datasets of stomach contents, stable isotopes, and taxa abundances. Despite strong resemblance in community structure, created marshes were at an earlier …

Teachers’ Voices On Multimodal Input For Second Or Foreign Language Learning, Mónica Stella Cárdenas-Claros, Tetyana Sydorenko, Elizabeth Huntley, Maribel Montero Perez

Applied Linguistics Faculty Publications and Presentations

Multimodal input – which combines written, auditory, and/or visual modalities – is pervasive in everyday life and could serve as a source of rich input in language teaching. In recent years, research has determined that vocabulary learning is one of the clear benefits of being exposed to such input. Regrettably, only a handful of studies have investigated whether and how second language (L2) teachers approach multimodal input in teaching. To further contribute to the research–practice dialogue, we examined factors that influence L2 teachers’ use of multimodal input in L2 teaching. This qualitative case study presents an in-depth analysis of interview …
