Seagrass ecosystems are considered some of the most productive coastal habitats in the world. One such seagrass within estuaries of the Pacific Northwest, Zostera marina (eelgrass), is recognized to be an ecosystem engineering species that provides many important ecosystem functions and services. In 2010, construction of the National Oceanic and...
For at least 30 years American culture has failed to provide empowering myths and symbols to its adolescents as they come of age and try to make sense of their selves, sexuality and the culture that surrounds them. This lack of myths and symbols is especially harmful to girls and...
Since the 1980s, NGOs have created a necessary niche for themselves within developing nations addressing poverty “traps” such as: lack of infrastructure, corruption, environmental degradation, conflict, disease, educational paucity, and gender inequality. Due to increasing issues of dependency and failed development projects resulting from a top-down, organizational structure, international nongovernmental...
MSME development has emerged at the forefront of economic policy, with the majority of policy mechanisms aimed at creating the regulatory and institutional environments, which have historically proven to augment entrepreneurial activity. In the case of Europe a large portion of entrepreneurial policy resides within the European Community framework, however...
The purpose of this essay is to explore the dynamics of social movements, and better understand why some populations succeed when others fail. This topic was motivated by travels across the United States and Europe. In these journeys, minority groups and their unequal treatment by society were a constant feature,...
Aromatic hydrocarbons represent a large class of environmental contaminants that have a broad range of structures, physicochemical properties, and toxicities. Arising from the burning of organic matter, particularly fossil fuels, they are both widespread and abundant in all environmental compartments. Both monoaromatic hydrocarbons (BTEX) and polycyclic aromatic hydrocarbons (PAHs) are...
Schools are continually faced with the challenge of providing students with a comprehensive system of support. Previous research based on the practices and systems of Positive Behavior Intervention and Supports (PBIS) suggests that having effective primary prevention measures in place can help to reduce problem behavior before it occurs (Ingram,...
A feature of large continental magmatic systems is voluminous dacite ignimbrites erupted from upper crustal magma reservoirs. In the Altiplano Puna Volcanic Complex (APVC) of the Central Andes, a major ignimbrite and caldera plateau, magma systems are found to be long-lived and remarkably homogeneous requiring that they be maintained by...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
Sexual and gender minority (SGM) samples report elevated rates of substance use and substance use disorder compared to their heterosexual and cisgender counterparts across a wide variety of substances (Connolly & Gilchrist, 2020; Krueger et al., 2020; Rice et al., 2019), in part due to the experience of minority stress....
Diverse scientific fields collect multiple time series data to investigate the dynamical behavior of complex systems: atmospheric and climate science, geophysics, neuroscience, epidemiology, ecology, and environmental science. Identifying patterns of mutual dependence among such data generates valuable knowledge that can be applied either for inferential or forecasting purposes. Vector autoregressive...
This study investigated the use of radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface. Laboratory physical aquifer models (PAMs), field experiments, and numerical simulations were used to investigate radon partitioning in static (no-flow) experiments and in single-well, 'push-pull' tests conducted in...
In the current global economy, higher education is critical for gaining and keeping living-wage jobs. The need for a college-educated labor force has increased interest among youth in pursuing higher education (National Center for Education Statistics, 2013). Despite these demands, the United States has struggled to effectively increase college completion...
A study to review the status and distribution of vascular plants at Lewis and Clark National Historical Park was initiated in 2009 and completed in 2010 by the Oregon Natural Heritage Information Center at Oregon State University. This study built on previous inventories conducted under the National Park Service‘s Inventory...
The 4.59-4.18 Ma Caspana ignimbrite, found within the Altiplano-Puna Volcanic Complex (APVC), is the result of an ~8km3 eruption that took place during the Neogene Ignimbrite Flare-up in the N. Chilean Andes. While most of the eruptions during this flare up are large, monogenetic eruptions, the Caspana that is characterized...
Grazing experiments were conducted in summer, autumn and winter
to assess the effects of stock density, grazing duration, pre-grazing
pasture mass and stock type on forage intake by sheep grazing at high
stock densities for short durations. In summer and winter, sheep were
stocked at 200 sheep/ha on 0.1 ha...
This dissertation investigates the context-dependency of species interactions between seagrass and macroalgae in upwelling-influenced estuaries. In all coastal systems, nutrient loading is multidirectional, resulting from mostly freshwater and marine inputs. The directionality of nutrient inputs may affect the rate of supply of organic matter to the system. In systems where...
The spatio-temporal overlap of morphologically undistinguishable weak and healthy stocks is a major concern for the Pacific Northwest troll Chinook salmon fishery. Regular fishery closures have led to major financial losses calling for alternative regulatory measures. One approach for such complex and pressing socio-ecological challenges is the transition towards transdisciplinary...
