Zinc sulfide thin films on silicon wafers were analyzed for layer thickness, refractive index, and absorption using reflection spectroscopy (RS), spectroscopic ellipsometry (SE), and modeling programs. RS and refractive index values from literature were used to model film thickness based on reflection and the SCOUT modeling program was used to...
Positive teacher-child relationships, characterized by warmth and closeness, are associated with better behavioral and academic outcomes for children in preschool and elementary school (Hamre & Pianta, 2005). Supporting teachers to establish these positive relationships with children is important in all early care and education (ECE) programs. Head Start programs, designed...
Globally, it is estimated that over 2,518,200 tons of hides and skins were exported in the year 2011 alone, with an estimated world production yield of 23 billion square feet of finished leather (FA0, 2011; Mwinyihija, 2011). While some manufacturers have adopted eco-friendly production methods, most tanneries still practice the...
Zebrafish are a powerful model organism to study disease. Like other animal models, Danio rerio colonies are at risk of pathogenic infection. Microsporidia, a group of intracellular fungus-like parasites, are one potential threat. Microsporidian spores germinate and spread causing pathological changes in the central nervous system, skeletal muscle, and other...
Design in secondary mathematics teacher education must prepare teacher candidates to do the work of ambitious and equitable mathematics teaching with skill by situating development in the work of teaching and incorporating opportunities to investigate and enact teaching. Teacher education designs must also be responsive to the work that mathematics...
Manuscript I: The removal of residual casting material from gating has traditionally been performed by abrasive grinding techniques. However, high amounts of belt wear can occur when working with high strength alloys, especially those typically seen in the aerospace industry. An alternative machining process called electrochemical machining (ECM) uses electrolysis...
Nuclear Factor, Erythroid Derived 2, Like 2 (NFE2L2 or Nrf2) is the primary transcription factor in cellular defense against oxidative and xenobiotic stresses in higher eukaryotes. This basic leucine zipper transcription factor regulates over 200 antioxidant, detoxification, and lipid metabolizing genes by binding to the Antioxidant Response Element (ARE; a...
An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...
First Ladies have performed a variety of public and private roles, from presidential escort, hostess, and social advocate to policy maker and presidential advisor. The nature of the position has always been both traditional and gendered, greatly influencing each First Lady's performance. Due to the changing role of women in...
