Leveraging the Power of Institutional Agents for Students of Color : Understanding the Factors Which Influence Engagement at Community Colleges

Creator:: Hernandez Chapar, Judith W.
Abstract:: Student engagement with faculty is positively associated with increases in the retention and graduation rates of students enrolled in institutions of higher education. Although a considerable amount of research has focused on understanding the engagement experiences of students enrolled at four-year colleges and universities, little emphasis has been placed on...

Chemical characterization of asphalt cements using chromatographic techniques : relation to rheological properties and field performance

Creator:: Thenoux, Guillermo
Abstract:: This dissertation presents the findings of a literature review and information regarding selection, implementation and development of a chemical composition procedure for asphalt cements. The chemical composition analysis selected was the Corbett-Swarbrick procedure standarized as ASTM D4124. The procedure is a selective adsorption / desorption (solid / liquid) chromatography which...

Non-viral Vectors for Ocular Gene Delivery

Creator:: Herrera-Barerra, Marco, F.
Abstract:: Nucleic acid therapeutics has cemented itself as one of the most efficacious and robust avenues for treatment of a wide range of diseases from vaccine development to treatment of liver, retina, cancer applications. Non-viral mediated gene delivery using lipid-based nanoparticle (LNP) carriers has proven its compatibility with addressing unexpected, fast...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Nutrient Addition Strategies for the Marine Diatom Cyclotella sp to Control Cell, Lipid, and Chitin Formation.

Creator:: Chiriboga Novillo, Omar Guillermo
Abstract:: Marine diatoms are unicellular photosynthetic organisms that produce unique nanomaterials, energy dense lipid-molecules, and specialty carbohydrate molecules that can be all extracted from a single microorganism. The centric marine diatom Cyclotella sp. was used as a model organism for cultivation in a biorefinery system, where multiple co-products can be harvested...

Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...

Tempo and Mode of Lineage and Morphological Diversification in a Hyperdiverse Freshwater Fish Radiation (Teleostei : Characiformes)

Creator:: Burns, Michael D.
Abstract:: Characiform fishes form one of the most diverse freshwater fish clades in the world. Comprising more than 2000 species and distributed primarily in South America and Africa, characiforms vary dramatically in their ecomorphology. However, the evolutionary processes responsible for the immense ecomorphological diversity remains unknown. Recently, a study postulated that...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Threat assessment in community colleges

Creator:: Bolante, Rebecca
Abstract:: The field of threat assessment and management in higher education is in the early stages of development. In particular, little is noted in the research literature about the practices of threat assessment teams in this environment. To fill this knowledge gap, a random national sample of 15% (n = 148)...
