The increasing move to citizen participation in policy formulation is being witnessed in European fisheries. The emergence of the Regional Advisory Councils (RACs) and other processes via the reformed Common Fisheries Policy (CFP) is sparking hope and interest in more regionally relevant, holistic, and hopefully workable fisheries management measures. In...
New Zealand manages commercial access and allocation through the market-based Quota Management System (QMS). However, the QMS alone is currently insufficient to address several fisheries issues. New Zealand is now developing Objectives-Based Fisheries Management (OBFM) to complement the QMS along two dimensions. First, to improve fisheries outcomes, such as reduced...
Western juniper has increased in density and distribution in the interior Pacific Northwest since the late 1800s. Management
goals for many juniper woodlands are now focused on reducing tree densities and promoting biodiversity, prompting the use of
fuel reduction treatments. Fuel reduction often involves mechanical cutting and disturbances such as...

Wetland prairies of the Willamette Valley, among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native pest species. Because fire has been important in maintaining Willamette Valley prairies for at least 1000 years, prescribed burning is a top choice of managers for preventing encroachment of...

This thesis examines the nature of evidence in scholarship on peer review in composition studies. I argue that the nature of evidence present in scholarship on peer review over the past three decades is typically anecdotal, theoretical, and based on limited case studies. I argue that peer review research in...
The results of an investigation into carrier dynamics in several novel functionalized and solution-processable pentacene and anthradithiophene derivatives are reported. Measurements were made of real-time photoresponse of polycrystalline thin films of these materials to ultrafast laser pulses, on picosecond to microsecond time-scales, as well as measurements of dark current and...
Restrictions on flows of foreign direct investment (FDI) in most sectors of OECD countries have been significantly reduced in recent years. In contrast, FDI in the fish harvesting sectors of OECD countries is still heavily restricted through a range of measures including outright bans on FDI, maximum allowable levels of...
At the 2001 WTO Ministerial Conference in Doha, World Trade Ministers called for improved disciplines on fisheries subsidies, given the perceived impact of these subsidies in contributing to overfishing, overcapacity and other trade distortions. Subsequent deliberations have sought to determine which fisheries subsidies should be disciplined under the WTO framework....
The concept of the "new father" has been discussed in the literature and popular

The concept of an ecosystem approach to fisheries management (EAF) is reaching a point of general acceptance by those involved in fisheries. There is also growing agreement that fisheries management must incorporate the complicated and often not-well-understood links between human activities and the environment. As a primary goal of an...
Why are fisheries policies so hard to reform? While there are many examples of successful policy reform in the sector, these tend to be restricted to a few countries or individual fisheries. There remains significant scope for further reform to address pressing economic, environmental and social issues in the sector....
The use and management of fish supplies, fish stocks and those who work in fishing and related businesses needs to be governed by good policies and actions, based as far as possible on good research-based advice and other expert information.

We characterized the structure and composition of unmanaged riparian forests in three river basins in Oregon’s coastal mountains. Our objective was to evaluate stand attributes at three spatial scales: streamside (site), drainage network (stream order), and basin (subregion). Data on basal area, species composition, snag density, canopy cover, and tree...
Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles).

Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...
The rate of removal of benzene, toluene, ethylbenzene and the xylene isomers (BTEX) from contaminated groundwater is needed to design remediation processes. Benzylsuccinic acid (BSA) and methyl-benzylsuccinic acid (methyl BSA) are unambiguous metabolites of anaerobic BTEX biodegradation. An analytical method for quantitative determination of BSA in groundwater samples was developed....
Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment.
