Nailed connections have nonlinear load-displacement
relations. Modeling these connections in an assembled
structure would require a great amount of computational time
because of the large number of degrees of freedom.
Replacing these connections with energetically-equivalent
nonlinear springs reduces the number of degrees of freedom,
and leads to computational efficiency in...
Timber harvesting practices can increase fine sediment inputs to streams due to increased hillslope soil erosion and mass wasting of roads, hillslopes, and stream channels. Excessive fine sediment depositions have been shown to impact aquatic ecosystems, fish habitat, and downstream community water supply. Despite these deleterious impacts, the influence of...
Mountainous headwater streams make up ~80 % of stream length globally and are strongly connected with catchment hillslopes and riparian areas, which can influence water quantity, quality, and availability for downstream uses. Accordingly, effective management of headwater streams and riparian zones to maintain desired ecosystem services downstream is critical, particularly...
This study explores how environmental governance mechanisms affect state management of forest roads to address the chronic delivery of sediment to streams in Oregon, Washington, and California on private and state forestlands. Forest roads can degrade water quality and harm aquatic life when runoff mobilizes fine sediments from the road...
Author Nella Larsen and photographer James VanDerZee are two of the most canonical figures of Harlem Renaissance studies, whose respective novels and portraits have been explored extensively, if separately, by scholars. Both Larsen's 1929 novel Passing and VanDerZee's studio portraiture of the 1920s and 1930s have been read in terms...
Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...
This is a collection of eight short stories, all of which deal on some level with
alienation and the struggle to find meaning in one's life. Although most of the stories deal
with issues related to women or feature female protagonists, I did not set out to create a
political...
Land management policies are ideas about nature projected onto the landscape. Culminations of social, economic, and scientific influences, these policies create standards affecting the function of ecological systems. In the case of riparian lands in the Oregon Coast Range, policy requirements vary considerably across federal, state, and private land ownerships....
My mother named me after Hollywood icon Katharine Hepburn, but what made a working-class girl grow to love this posh celebrity so much? The obvious answer is that my mother aspired to be posh herself; but lack of money or sophistication were not the only things impacting her potential— there...
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...
