In this thesis, we present semantic equivalence rules for an extension of the choice calculus and sound operations for an implementation of variational lists. The choice calculus is a calculus for describing variation and the formula choice calculus is an extension with formulas. We prove semantic equivalence rules for the...
Granting catch shares to cooperatives is a fisheries management option that has been widely applied. Although fishery cooperatives systems around the world are structured in various ways, it appears that most share the characteristic that members of the same cooperative are jointly and severally liable for not exceeding collectively assigned...
This research examines the gendered livelihood implications of fisheries management decisions through an exploration of a seasonal ban on fishing. The 45 day closed fishing season on the Eastern coast of India began in 2001 and applies to mechanized boats. While there is existing research on the impact of the...
Wildfires are keystone components of natural disturbance regimes that maintain ecosystem structure and functions, such as the hydrological cycle, in many parts of the world. Consequently, critical surface freshwater resources can be exposed to post-fire effects disrupting their quantity, quality and regularity. Although well studied at the local scale, the...
A new Fe-based metallic glass with composition Fe₇₆B₁₂Si₉Y₃ (at. %) is found to have extraordinary degradation efficiency towards methyl orange (MO, C₁₄H₁4N₃SO₃) in strong acidic and near neutral environments compared to crystalline zero-valent iron (ZVI) powders and other Fe-based metallic glasses. The influence of temperature (294–328 K) on the degradation...
In 2014, the Washington State Legislature directed the creation of the Fish Barrier Removal Board (FBRB), a multi-entity committee tasked with the development of a statewide strategy for removing anadromous fish barriers. The strategy shall identify watersheds with the greatest potential for salmon and steelhead recovery and implement the removal...
Purpose of the Study: We tested a life-span model of combat exposure on posttraumatic stress disorder (PTSD) symptoms in later life, examining the direct and indirect effects of prewar, warzone, and postwar factors.
Design and Methods: The sample included 947 male World War II and Korean War veterans from the...
Two faculty-librarians in the US led a small group of undergraduate students from Oregon State University on a short-term study abroad to Barcelona in the summer of 2016. While in Barcelona the librarians and one of their students delivered a presentation to librarians in Catalonia. The paper presentation detailed the...
Capturing breeding adults of colonially nesting species can entail risks of nest failure and even colony abandonment, especially in species that react strongly to human disturbance. A low-disturbance technique for capturing specific adult Double-crested Cormorants (Phalacrocorax auritus) at a ground-nesting colony was developed to reduce these risks and is described...
The recent history of fisheries management in New England has seen substantial interannual variability in total allowable catches (TACs), with stocks deemed healthy in one year retroactively identified as overfished soon thereafter. Concurrently, avenues for and examples of coordination between fishermen are increasing in the region, as exemplified by the...
A new matrix operator framework is developed to analyze results from climate modeling studies that employ numerical water tracers (WTs), which track the movement of water in the aerial hydrological cycle from evaporation to precipitation. Model WT output is related to the fundamental equation of hydrology, and the moisture flux...
The emergence of altmetrics has drawn the attention of academic libraries as a new and effective approach for capturing the types of impact often ignored by traditional citation-based metrics. At Oregon State University Libraries, before investing in a full-scale implementation of altmetrics services, we conducted an assessment survey of faculty...
The Community Engagement Core of OSU's Superfund Research Program aims to increase cultural capacity among university scientists while simultaneously supporting research focused on reducing health disparities for Pacific Northwest Tribes originating from harmful chemical exposures in the environment.
Conflicts over the use of coastal areas are expected to increase in Norway in the future. In Northern Norway, salmon aquaculture and marine fishing tourism are expected to expand, affecting both the space available for other uses and ecosystems, including traditionally harvested fish stocks. While data is available to managers...
This paper addresses adverse incentives built into the process of TAC setting as an instrument to prevent overfishing in multispecies fisheries. Under the Magnuson Stevens Act (MSA), the primary law governing marine fisheries management in U.S. federal waters, regional Fishery Management Councils must develop a rebuilding plan for every overfished...
A quarter of biomass losses in Scottish marine Atlantic salmon aquaculture are attributable to infectious disease. Interventions to reduce the consequences of disease include the use of disease-resistant stock, vaccines and other authorised medicines, functional feeds, and modified farm management strategies. There are, however, only a few evaluations of the...
The objective of this paper is to look at past assessments and available data to examine the match (or mismatch) between university curricula and programs available to graduate students in the ocean sciences and the career possibilities available to those students. We conclude there is a need for fundamental change...
Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...
