PART I. Asymmetric syntheses of both natural (+)- and nonnatural (-)-byssochlamic acid via a [2+2] photoaddition-cycloreversion strategy are described. X-ray crystallographic analysis of the cyclohexylamine salt 99 showed that the structure of the monomethyl ester 100 from esterase hydrolysis of 44 was originally misassigned as 56. The enantiomeric relationship of...
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...
