An inducible, mutant virus, designated vvtetO:I7L/G1L, was used to study the morphogenic proteolysis step of the vaccinia virus life cycle. The vvtetO:I7L/G1L controlled the expression of two genes, I7L, a cysteine proteinase, and G1L, a putative metalloproteinase. These proteins are involved in the maturation of viral core proteins, p4a, p4b,...
The mechanisms of mortality during critical life stages of fish are not well-understood and, for many species, it is not clear if the mechanisms are similar for naturally and artificially propagated individuals. For Chinook salmon (Oncorhynchus tshawytscha), natural fish potentially face negative interactions, such as competition, and survival disadvantages, such...
Early life stages of many marine and diadromous fish species use sandy beach surf zones, which occur along >50% of the world's marine coastlines. This extensive habitat can provide juvenile fishes with an abundant supply of potential prey and the ability to hide from predators in its shallow turbid waters....
Olympia oysters, “Ostrea conchaphila,” were once common along the west coast of North America. A popular delicacy, native oyster populations began to decline in the late 1800’s due to over‐harvest, degraded water quality, and habitat loss. Interest in re‐establishing the native oyster in a small Oregon estuary, Netarts Bay, culminated...
Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...
The graduate student population has been traditionally overlooked within higher education. However, within recent decades, much research has been devoted to addressing the multiple facets of the graduate student experience, including that of the graduate teaching assistant (GTA) position. This thesis seeks to explore in depth the experiences of GTAs...
In recent decades, there has been a tremendous change in the college student
experience. In many ways this change has been driven by developments in
technology, which have in turn changed the way students conduct research,
socialize, and recreate. This thesis seeks to gain an understanding as to how
Internet...
The purpose of this study is to identify factors that support the likelihood of persistence of academically underprepared community college students to 45 college level credits. Factors considered in this research include: (a) race/ethnicity, (b) age, (c) enrollment status, (d) socio-economic status (SES), (e) first quarter GPA, (f) developmental need,...
Involvement in student leadership provides opportunities for student development (Foubert and Grainger, 2006) and is linked with higher rates of persistence (Astin, 1984), making leadership programs an important tool for increasing the retention and success of students of color. Unfortunately, traditional leadership paradigms often used in student leadership programs are...
This thesis examined the identity transitions that occurred prior to enrollment at a predominantly, White, large, public research university and after completing at least one year of college for students who identify as multiracial. As a secondary purpose, this thesis also examined whether these students sought support through groups that...
