This issue of the PMFC bulletin centers on sablefish along the Pacific Coast, describing the fisheries of California, Oregon, and Washington. It also has the results of a racial study of Pacific Coast sablefish, and has the results of sablefish tagging experiments in California, Oregon, and Washington.
Policy and research have increased attention in K12 mathematics education on core mathematical practices such as argumentation, justification, and proof, that are central to students learning and doing mathematics. One reason for this increased focus is the empirical evidence that engaging students in mathematical practices provide more equitable opportunities for...
The Phase 1 report is an overview of the complex water quantity and quality information and issues specific to Benton County. It is a first step toward assessing and planning for future water quantity and quality within Benton County and provides a template for regional water planning. The report details...
Federally designated wilderness areas in the United States are uniquely required to provide opportunities for particular types of recreational experiences. According to the Wilderness Act of 1964, the law that governs the management of designated wilderness in the U.S., wilderness areas are to provide “outstanding opportunities for solitude or a...

As climate change contributes to larger and more severe wildfires in California, areas of fire refugia – considered unburned and low-severity burn patches – are playing an increasingly important role in sustaining ecosystem resilience, maintaining biodiversity, and supporting post-disturbance recovery. At the same time, climate refugia – which are areas...
Ixodes scapularis (e.g. blacklegged tick) is a hard-bodied tick considered endemic to certain regions within the United States. This species is considered a primary vector of Lyme disease (Borrelia burgdorferi), anaplasmosis (Anaplasma phagocytophilum) and babesiosis (Babesia microti). Each of these tick-borne diseases represent a growing health concern within the nation...
This study was concerned with the estimation of transition probabilities
in a finite state Markov-type student flow model. Goals
setting for this study were three in number: (1) Study of the methods
which will provide conclusions that (a) the transition probabilities
are stationary or nonstationary and (b) the process is...
Reactor refueling is a computationally intensive
problem solving process that requires automation since
significant resources are expended upon the search for
an optimal core loading. Without imposing some
constraints upon the configurations investigated, an
extremely large number of prototype loadings may be
generated without discovery of an improved loading. As...
