Norbert Wiener and the growth of negative feedback in scientific explanation : with a proposed research program of "cybernetic analysis"

Creator:: Hellman, Walter Daniel
Abstract:: Negative feedback has become ubiquitous in science both as a technique and as a conceptual tool. As a technique, negative feedback has a long history; devices based in its use were made in antiquity. It has only been during the last century, however, that rigorous quantitiative methods have become associated...

The fluvial response to glacial-interglacial climate change in the Pacific Northwest, USA

Creator:: VanLaningham, Sam J.
Abstract:: This research focuses on the development of new techniques to explore terrestrial-ocean climate linkages along the Pacific Northwest-northeast Pacific Ocean margin. This is done by investigating river response to climate change and by unraveling this history preserved in continental margin sediments. A significant component of this work centers on developing...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...

Systems tableau : an integrated approach to systems theory

Creator:: Inoue, Michael Shigeru
Abstract:: Systems Tableau is suggested as a convenient tool for the integration of the three phases of systems theory: the synthesis of a model from the analysis of a system; the evaluation of the model; and the decision-making process for the design and control of the resulting system. From a basic...

Zooplankton of the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The marine climate of the Galapagos is spatially and seasonally heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has never been done. This study is an initial effort to establish the distribution and community structure of zooplankton in the Archipelago. I collected zooplankton samples by vertical tows over the Galapagos...

Characterization of Mycobacterium avium subsp. hominissuis Interactions with Host Macrophages and Multinucleated Giant Cells

Creator:: Joseph, Jayanthi J.
Abstract:: To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

New Applications for Passive Samplers : In-situ Flux and Risk Assessment of Legacy and Emerging Contaminants

Creator:: Tidwell, Lane G.
Abstract:: Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...

Ecosystem Functions of Pacific Northwest Estuaries: The Role of Ocean and Watershed Drivers in Eelgrass and Coho Salmon Dynamics

Creator:: Magel, Caitlin L.
Abstract:: Interest is expanding for the potential role of estuaries, particularly seagrass and salt marsh habitats, to sequester carbon, mitigate ocean acidification, and support abundant fisheries. The important functions of estuaries are part of a broader set of ecosystem services, or benefits to humans, which are regulated by ocean and watershed...

Functional Characterization and Classification of Genes Essential to Flower Induction, Flower Development, and Seed Development in Populus and Eucalyptus

Creator:: Elorriaga, Estefania
Abstract:: This dissertation consists of four studies of Populus and Eucalyptus biotechnology and genomic science: 1) induction of floral sterility by tapetal expression of the ribonuclease Barnase in Populus; 2) CRISPR Cas9-mediated gene editing targeting LEAFY (LFY) and AGAMOUS (AG) homologs in Populus; 3) induction of floral sterility by CRISPR Cas9...
