Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...
In explaining why service prices differ across countries
(both developed and developing countries), most studies have
paid attention to the role of structural variables such as
population, trade balance, resource abundance etc., by using
a full employment assumption. Due to the existence of high
urban unemployment in developing countries, the...
Self-regulation skills lay the foundation for short- and long-term school success, and strengthening these skills in early childhood can have significant implications for immediate and future life outcomes (e.g., Blair & Diamond, 2008; McClelland, Acock, Piccinin, Rhea, & Stallings, 2013). A large body of literature has investigated how characteristics of...
Most marine fishes experience high rates of mortality during their early life history stages with far reaching consequences for adult population dynamics. Within a few weeks of hatching, relatively small changes in larval growth and mortality rates can lead to orders of magnitude variability in year-class strength. Growth and survival...
Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...
The primary purpose of this study was to determine which factors related to adult 4-H volunteer empowerment in 4-H youth development settings. This study examined the relationship of adult 4-H volunteers’ perceived leadership styles of Oregon 4-H Youth Development Educators (YDE) to the adult 4-H volunteer sense of empowerment. In...
Irrigated agricultural production in sandy soils presents several unique challenges to growers, including naturally high permeability, low native water retention, as well as high rates of water drainage losses and leaching of chemicals to the shallow aquifers. This study is an initial investigation into water motion in the sandy agricultural...
In recent years, depletion of sands in the nearshore environment along the northern Oregon and southwest Washington coasts has been documented. This erosion raises concerns about protection of economic and ecological resources in the area. The Columbia River Nearshore Beneficial Use Project was initiated to engage public and private sector...

Campus administrators are partially responsible for how a campus responds to a critical incident and how the students and outside community are impacted. It is important for administrators responding to critical incidents to take an objective look at their plans and preparations to determine if they will truly be effective...
