Endogenous and antiviral RNA silencing pathways in Arabidopsis

Creator:: Chapman, Elisabeth J.
Abstract:: RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

The Graham Model of bibliosupervision : A multiple-baseline analysis

Creator:: Gauntz, Mary
Abstract:: This dissertation presents the Graham Model of Bibliosupervision (GMB). The purpose of this study is to examine the efficacy of the GMB and its influence on the supervisory working alliance. Specifically this study examines the effectiveness of a non-linear approach to counselor supervision that employs children’s literature as part of...

Comparing lifespan and life course perspectives on combat exposure and PTSD symptoms in later life : findings from the normative aging study

Creator:: Kang, Sungrok
Abstract:: We examined how the experiences of World War II and Korean War veterans, including prewar, warzone, and postwar factors, affected PTSD symptoms in later life. This dissertation consists of two studies. In Study 1, four different hypotheses from a lifespan approach were examined (King et al., 1996): stress evaporation (only...

Passive sampling devices as biological surrogates for evaluating seasonal bioavailability of hydrophobic organic contaminants in surface water

Creator:: Sethajintanin, Doolalai
Abstract:: The seasonal distribution of bioavailable organochiorine contaminants in surface water and the potential environmental factors influencing their bioavailability were evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon where surface water runoff varied according to season. Bioavailable water concentrations of DDTs and PCBs were determined...

Processing and functional diversity of plant microRNA

Creator:: Cuperus, Josh
Abstract:: RNA interference pathways can involve amplification of secondary siRNAs by RNA-dependent RNA polymerases. In plants, RDR6-dependent secondary siRNAs, including transacting siRNAs (tasiRNAs), arise from transcripts targeted by some microRNAs (miRNAs). In the case of TAS3 tasiRNA formation, ARGONAUTE7 (AGO7)-miR390 complexes interact with primary transcripts at two sites, resulting in recruitment...

Quantification of vegetation diversity and variation on intact and degraded rangelands

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...

Education of American research astronomers, 1876-1941

Creator:: Hall, Robert Dale, 1947-
Abstract:: The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration

Creator:: Clemens, Benjamin J.
Abstract:: Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...

Is family beyond justice? : exploring determinants of wives' perceived fairness about the division of household labor and child care in Thailand

Creator:: Surinya, Tippavan
Abstract:: The researcher 1) explored Thai employed wives' perceived fairness in the division of household labor and child care, 2) investigated factors determining Thai's working wives' perception of fairness in the division of household labor and child care, and 3) developed a model of the determinants of wives' perceived fairness in...

Structural oppression of African Americans in higher education

Creator:: Powell, William N.
Abstract:: Researching what I believe to be exclusionary practices in higher education against African Americans has compelled me to approach this subject, in part, historically. Although I realize that a historical chronology of any subject is often deceptive, as with any writer, I am tempted to interpret events to fit my...
