The purpose of this dissertation is to investigate Oregon public high school history teacher perspectives concerning standards-based reform initiatives springing from the No Child Left Behind legislation. The central question addressed in this study is: At what level has Standards-Based Education reform initiatives impacted Oregon high school history instruction and...
Polynuclear aromatic hydrocarbons (PNAH) classified as noncarcinogens
may be photooxidized to mutagenic or toxic products by
near-ultraviolet (NUV) wavelengths of sunlight (290-320 nm). The
possibility that this represents a major degredation pathway in the
aquatic environment is of increasing concern. Large quantities of
PNAH from accidental oil spills, anthropogenic and...
Spotted knapweed, Centaurea maculosa Lam. (Compositae) is an extremely
successful introduced weed species in the northwestern United States. Multiple factors
may be responsible for its success, including chemical defense. Two different types of
putative chemical defense agents are the focus of this thesis. The first is a bitter-tasting
sesquiterpene lactone,...
This thesis focuses on two aspects of transparent electronics, SnO₂ transparent thin-film transistors (TTFTs) and transparent circuits. Both depletion- and enhancement-mode SnO₂ TTFTs are realized. The maximum effective mobility for the depletion- and enhancement-mode devices are 2 cm²V⁻¹s⁻¹ and 0.8 cm²V⁻¹s⁻¹, respectively. A variety of techniques to decrease the carrier...
This thesis examines the application of findings from the social psychological field of
procedural justice to public involvement in natural resource decision making. The
methodological approach involves examining the literature of each of the fields and
developing a synthesis applicable to public involvement. The review of public involvement
literature reveals...
We hypothesized that calpain activity is elevated in response to muscle damage. To test this hypothesis, we examined the degradation of α-fodrin into its 150 and 145 kDa fragments following either 20 eccentric or isometric contractions. In addition, experiments were performed in the presence or absence of E-64-d, a calpain...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
In two twelfth grade Homemaking classes a home furnishings
unit was taught to develop creativity in the students in the classes in
order to:
1. Attempt to give students creative experiences in the home
furnishings unit which would in turn motivate them to be creative.
2. Develop learning experiences in...
