This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...
Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...
Disturbance processes of various types substantially modify ecosystem carbon dynamics both temporally and spatially, and constitute a fundamental part of larger landscape-level dynamics. Forests typically lose carbon for several years to several decades following severe disturbance, but our understanding of the duration and dynamics of post-disturbance forest carbon fluxes remains...
Two striking characteristics of human beings are the diversity of resources that we use to sustain our lives and the extent to which we engage in coordinated, collective efforts to obtain and consume these resources. Together, these two characteristics are the foundation of human subsistence patterns. In many remote Alaskan...
This annotated bibliography contains 392 published and unpublished
references that pertain to the natural resources in the Lake Washington
watershed, with particular emphasis on the aquatic environment. All
references are indexed by keywords.
This research seeks to understand the influences of perception on land use around
the Mount Hood area of Oregon and evaluate how it has evolved over the past 4,000
years. The study addresses three specific questions:
1) How has the study area evolved over time into the modern landscape?
2)...
This thesis employs the study of gender to demonstrate how recent Hollywood
western films have constructed a hero that is reflective of contemporary beliefs
regarding masculinity. Beginning with a New Historicist approach at studying gender,
this work first considers the construction of masculinity in post World War II America
and...
The purposes of this investigation are twofold: (1) to identify the functions necessary for an adequate student personnel program in the two-year community college and (2) to develop guidelines based on the functions identified. Securing And Treating Of Data: The data for this study were obtained by using a questionnaire...
The greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) is a ground nesting gallinaceous bird that requires large contiguous patches of sagebrush. Sage-grouse populations have declined, especially in the Great Basin where changes in wildfire regimes and the invasion of annual grasses have contributed to habitat loss and fragmentation. During the last...
The longshore variability of the coastal response to hurricanes may be examined within the framework of a storm-impact scaling model that compares spatially-variable beach morphology and fluid forcing. The relative elevations of dune height and storm-induced water levels are used to define three impact regimes (swash, collision, and overwash), within...

Purpose: Increasing enrollment numbers of multicultural students, and growing research between the relationship between student engagement and student success and retention heighten the importance of addressing student engagement in campus recreation. This study was conducted to explore the facilitators and barriers to underserved students participating in physical activity through campus...
A major challenge to the study of the peopling of the Americas is that much of the Bering Land Bridge (Beringia), the geographic area that people migrating from Northeast Asia into North America would presumably have passed through, is now submerged due to sea-level rise since the last glacial maximum....
This index provides access to infonnation about women in 102 books and journals. The information contained in each entry is only as good as the original and the quality varies considerably. Much of this infonnation has not before been easily accesible in this form. My hope is that this index...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
The purpose of this study is to determine if the problem of
scheduling instructors to classes can be formulated as a linear
program involving integer variables limited to values of zero and
one. Once such a formulation is accomplished, attempts at electronic computer solution of the problem are considered.
Specifically,...
Oakland is a quiet, peaceful little town on the Calapooya Creek surrounded by rolling hills and little valleys. This little booklet is written with the intention of preserving the history of our pioneers and contains a number of the names of the people who took doriation Land Claims and is...

Microorganisms can be a valuable tool in assessing the toxicity of heavy metals. The soil respiration rate is a commonly explored endpoint. I utilized a fully automated respirometer incorporating an infrared gas analyzer (IRGA) and developed a method for measuring the effect of Zn on soil microbial populations. Zinc, in...
One hypothesis proposed to explain how the endocrine
system controls reproductive cycles in seasonally breeding
animals is that the hypothalamus undergoes seasonal
changes in sensitivity to negative feedback by gonadal
steroids. The result is seasonal changes in the secretion
of luteinizing hormone-releasing hormone (LHRH) and
gonadotropin secretion. The present experiments...
The purpose of this study was to provide a history of the Business
Education and Secretarial Science departments at Oregon State
University. The historical-documentary method of research was
used. Extensive use was made of interviews with those involved in
the school's history. The chronology of history was divided into segments...
The purpose of this research was to determine if there were any relationships between measured personality traits and vocational interests between the Adult Learner with Learning Disabilities (ALLD) and without Learning Disabilities (ALNLD). Instruments utilized to measure personality traits and vocational interests included the Myers Briggs Type Indicator (MBTI) and...
The Lakes Basin Bibliography consists of over 600 references relating to the natural resources of Oregon’s Lakes Basin. Forty percent of the items listed are available to anyone online though not all links are persistent. The remaining sixty percent are held in at least one library either in print or...
Dysregulation of Sonic hedgehog (Shh) signaling has been implicated in glioma pathogenesis. Yet, the role of this pathway
in gliomagenesis remains controversial because of the lack of relevant animal models. Using the cytokeratin 5 promoter, we
ectopically expressed a constitutively active zebrafish Smoothened (Smoa1) in neural progenitor cells and analyzed...

Sedoheptulose 7-phosphate cyclases (SH7PCs) encompass three enzymes involved in producing the core cyclitol structures of pseudoglycosides and similar bioactive natural products. One such enzyme is ValA from Streptomyces hygroscopicus subsp. jinggangensis 5008 which makes 2-epi-5-epi-valiolone as part of the biosynthesis of the agricultural antifungal agent validamycin A. We present, as...

Some export fisheries in Australia have opted for third party certification to gain or maintain access to export markets. For domestic fisheries, the economic and management benefits of third party certification have yet to be fully demonstrated. However, as a response to community perceptions, competition with other users of the...
