New ice core analyses show that the prominent rise in atmospheric methane concentration at Dansgaard-Oeschger event 21 was interrupted by a century-long 20% decline, which was previously unrecognized. The reversal was found in a new ∼100-year resolution study of methane in the GISP2 ice core, encompassing the beginning of D-O...
The global biogeochemical cycle of methane has received wide attention because of methane's role as a greenhouse gas. Measurements of methane in air trapped in Greenland ice cores provide a high-resolution record of methane levels in the atmosphere over the past ~100 ka, providing clues about what controls the methane...
Dual Language Learners (DLLs) represent a substantial subpopulation in United States preschool programs (Aikens, Kinas, Malone, Tarullo, & Harding, 2017). DLLs often come from low socio-economic backgrounds and encounter barriers to academic success (National Academies of Science, 2017; Thomas & Collier, 2002). One consistent predictor of academic success is executive...
In the United States, children from underserved racial/ethnic backgrounds encounter greater environmental risk both in terms of the physical environment (e.g., housing quality, access to resources like health services and jobs, and exposure to environmental toxins) and the social environment (e.g., social support, neighborhood crime, racism, and discrimination), due to...
Retirement is a later life transition that may affect a variety of areas in a person's life. One area is the division of household labor. Historically, women have been responsible for and performed the majority of household labor. Women's responsibility for household labor follows the traditional dual sphere ideology, which...
Oregon's commercial fishery for albacore tuna (Thunnus alalunga)
is large, valuable, and variable. Little is known, however, about the
oceanographic factors which determine abundance and distribution of
albacore.
Primarily using logbook data contributed by fishermen, this study
compares albacore catches with selected ocean conditions. The study
is limited to troll-caught...
Positive teacher-child relationships, characterized by warmth and closeness, are associated with better behavioral and academic outcomes for children in preschool and elementary school (Hamre & Pianta, 2005). Supporting teachers to establish these positive relationships with children is important in all early care and education (ECE) programs. Head Start programs, designed...
Rare plant reintroductions that result in additional or more viable wild populations are important conservation tools for maintaining biodiverse ecosystems. Ideally, such projects are best designed as experiments, to improve biological and ecological knowledge of the selected species and monitoring long-term results. Northern wormwood (Artemisia campestris var. wormskioldii: Asteraceae), a...
Coastal communities throughout the U.S. Pacific Northwest face heightened risk due to sea level rise and increasing storminess resulting in coastal flooding and erosion hazards. Incorporating uncertainty with respect to both climate change and policy decisions is essential to project the evolving probability of coastal inundation and erosion, and the...
Wildland firefighting is environmentally and socially a risky and complex occupation. Although much attention has been given to understanding the physical components in fighting wildland fire, much less time has been devoted to understanding and developing the capacity of wildland firefighters to handle the dynamic pressures of the physical and...
