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...
Compassion fatigue is a common struggle that helping professionals face; however, it is not yet well understood in early childhood teachers. Compassion fatigue results from caring for individuals who have had traumatic experiences, which can cause physical and emotional exhaustion, leading to a diminished ability to empathize with individuals in...
Early behavioral regulation has been identified as an important component of school readiness, yet few easy-to-administer measures exist that directly assess this skill in young children outside of the United States (U.S.). In this dissertation, two studies were conducted to examine the reliability and validity of a direct measure of...

The purpose of this study was to understand the influence of organic material and nutrients from spawning salmon and supplemented salmon carcasses on stream food webs. My study objectives were to examine 1) assimilation of salmon-derived nutrients (SDN) by producers and consumers in the food web, 2) epilithic biofilm productivity,...
Celiac disease, an autoimmune response triggered by the consumption of seed storage proteins of cereals, affects an estimated 1% of the human population. In the case of wheat (Triticum aestivum L.), one of the world’s most consumed cereals, alcohol-soluble proteins, the gliadins, have been identified as the allergy-eliciting agents. Previous...
Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...
Immune-mediated diseases are a frequent cause of morbidity and mortality in canine patients. Treatments currently involve generalized suppression of the immune system, and corticosteroids are often used as a first-line agent. While often effective, corticosteroids are unlikely to induce remission without substantial side effects. Second-line immunosuppressive agents may be effective...
The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...
The undisputed cost-effectiveness of the anti-homelessness program “Housing First” is well established in the empirical literature, but fewer studies have considered the impact of the program on individual residents. This mixed-methods study examines the lives of a cohort of residents in a Portland-based Housing First project, seeking to determine whether...
