Black vine weevil (BVW), Otiorhynchus sulcatus Fabricius, is a serious pest in cranberry, Vaccinium macrocarpon. Larvae feeding below the soil surface cause damage to the roots and underground stems. Knowledge is sparse in regard to the damage potential of BVW in Pacific Northwest cranberry beds. Control with insecticides is limited...
Networks are a structure common to many disciplines. Research on
networks has taken different forms in domains such as graph theory, sociology,
vascular networks, small-world networks, geomorphology, ecology, evolution and
engineering. Networks may be modeled as non-spatial networks (unvalued
graphs), which contain only topological information, or as spatial networks (valued...
Within the United States, international student enrollment in institutions of higher education has been climbing sharply over the past decade. However, despite this increase, colleges and universities largely do not adequately support these student and their unique needs within higher education. International students who identify as lesbian, gay, bisexual, trans,...
In cranberry (Vaccinium macrocarpon Aiton) cultivation, farmers typically rent colonies of honey bee (Apis mellifera) for pollination. However, the efficiency of this bee at pollinating cranberries in Oregon, as in other regions, is questionable. Bumble bees (Bombus sp.) are reportedly effective in other regions, but their impact in Oregon is...
The objective of this research is to examine capital market determinants and implications associated with voluntary sustainability disclosures and the extent to which the informativeness of disclosure innovations differs based on given attributes of the financial disclosure and overall information environment.
In determining the quantity of financial information to disclose,...
Society uses massive quantities of wood fiber in production of paper, and demand for fiber is projected to increase further as production of biofuels from fermentation of plant cellulosic materials increases. Because these end uses generally require the costly step of removing of lignin, wood with reduced or more easily...
Latina/o student enrollments in community colleges in the United States are rapidly growing, yet Latina/o student success rates have not matched this growth. There is a need for community college programs that serve Latina/o student populations more effectively and that incorporate multicultural educational practices into college programs. The purpose of...
The fishing industry in the Pacific Northwest is a dynamic and highly competitive industry that must constantly respond to rapidly changing resource, regulatory and market forces. These forces have already had a significant impact on our fisheries and will continue to do so as we learn more about the biology...
Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency.
This study will examine driver behavior in standing queues...
In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of
grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...
