Extensions to Gaussian copula models

Creator:: Fang, Yan
Abstract:: A copula is the representation of a multivariate distribution. Copulas are used to model multivariate data in many fields. Recent developments include copula models for spatial data and for discrete marginals. We will present a new methodological approach for modeling discrete spatial processes and for predicting the process at unobserved...

Assessing the knowledge of county extension agents on geotextile applications for agricultural practices in Oregon and Idaho

Creator:: Brown, Linda Lee
Abstract:: The purpose of the study was to assess county extension agents' knowledge of geotextiles; to determine their current level of information and their location on an adoption-diffusion curve; and to determine the agents' attitudes toward the potential use of geotextiles in agriculture, specifically in soil erosion control. A questionnaire was...

Examining the Contribution of Self-Regulation and Executive Function Skills to School Readiness and Longer-Term Achievement Gaps: A Replication and Extension in Statewide and National Datasets

Creator:: Finders, Jennifer K.
Abstract:: Self-regulation in early childhood encompasses higher-order executive function processes and lower-order emotional responses that enable children to navigate the classroom environment. Although self-regulation and executive functions are overlapping constructs, self-regulation represents a broad assessment of children’s ability to call upon executive function processes in order to meet contextual demands. Prior...

The Deschutes Formation: evidence of extension-enhanced explosivity in the early High Cascades

Creator:: Pitcher, Bradley W.
Abstract:: The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...

Novel Extensions and New Applications for Nonparametric Self-Exciting Point Processes

Creator:: Boyd, Peter C.
Abstract:: In this dissertation I will demonstrate a novel application of self-exciting point process models to mass shooting data. I will also introduce two adaptations to the traditional nonparametric Hawkes process modeling framework. One such modification allows for the estimation of the additional productivity introduced by an event that is not...

Seismicity at the Cascadia plate boundary beneath the Oregon continental shelf

Creator:: Williams, Mark Charles
Abstract:: Since 2003, 39 small earthquakes have been detected offshore central Oregon in the nominally locked part of the Cascadia subduction zone, where very little seis- mic activity has been recorded in spite of a paleo-seismic record of great subduction events. Although the regional earthquake bulletin reports depths of 29 and...

Exploring Advancements in Rural Equity and Prosperity in the Oregon Labor-Intensive Forest Industry: The Practical Application of Transdisciplinarity and Science Communication

Creator:: Alessi, Gianna
Abstract:: Disproportionate exposure to exploitative working conditions, social marginalization, and a lack of equitable living conditions are among the many issues that migrant Latinx populations face daily in the United States. However, such issues cannot be addressed by relying solely on traditional academic research approaches without the participation and direction of...

All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

Creator:: Hamner, Rebecca Marie
Abstract:: The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...

Early Adventures of a Home Economist: Ava B. Milam’s Integration of Science and Home Economics at Oregon Agricultural College, 1911-1921

Creator:: McHugh, Kathleen M.
Abstract:: Across from the Memorial Union on Oregon State University’s campus sits Milam Hall, the former site of the Department of Home Economics. The building is named for Ava Milam Clark, the dean of home economics for thirty-three years, from 1917 to 1950. I aim to understand Ava Milam’s early career...

Case study of the student-to-student interactions in an online course offered by a community college, and how the interactions impact learning community

Creator:: Cvetko, Marlene G.
Abstract:: This study was conducted to investigate the student-to-student interactions that take place in an online community college course, and how the interactions impact an online learning community. The literature review revealed three related themes: (a) the impact of the teaching/learning environment on student interaction, (b) barriers in the online environment,...

Utilizing cooperative fisheries research to monitor and understand harmful algal blooms along the Oregon coast

Creator:: Gilliland, Raquel C.
Abstract:: Harmful algal blooms (HABs) are a problem for coastal communities, the fishing industry, and coastal organisms. Pseudo-nitzschia spp. is a regularly occurring diatom in Oregon’s coastal waters. At times, Pseudo-nitzschia spp. can facultatively produce domoic acid, a neurotoxin that can bioaccumulate in the food chain. While regular shore-based sampling provides...

Extensive Resource Subsidies by Salmon-Supported Bears to Granivores

Creator:: Shakeri, Yasaman N.
Abstract:: In salmon-rich, northern coastal environments brown bears can occur at high densities and exert wide-ranging effects on ecosystem processes. Bear consumption of seasonally available fruit may provide important seed dispersal services to plants, and by extension, influence the ecology of seed consumers such as small mammals. In this study, we...

Journey to the Center of GW170817: Bayesian parameter estimation of outflows from binary neutron star mergers

Creator:: Rodriguez, Isabel J.
Abstract:: The discovery of GW170817 provided the first empirical evidence that merging binary neutron star systems are both progenitors of short gamma-ray bursts, as well as the primary sites of the nucleosynthetic rapid-neutron capture process. Initially detected as gravitational wave (GW) and gamma-ray burst (GRB) triggers, GW170817 was well-localized and follow-up...
