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...
This study examined children’s self-regulation, demographic risks [English Language Learner (ELL) status, being from a low-income family], and academic achievement longitudinally across four time points (fall and spring of the prekindergarten and kindergarten years). Findings suggested that assets such as high self-regulation in the fall of prekindergarten were significantly related...
A growing body of research suggests that behavioral self-regulation skills are critical for early
school success. However, few studies have explored the links between self-regulation and
academic achievement among young children in Europe. This study examined the contribution of
behavioral self-regulation to academic achievement gains among young children in France,...
The present study investigated a direct assessment of behavioral self-regulation (the Head-Toes-Knees- Shoulders; HTKS) and its contribution to early academic achievement among young children in Germany and Iceland. The authors examined the psychometric properties and construct validity of the HTKS, investigated gender differences in young children’s behavioral self-regulation, and explored...
The current study investigates gender differences in behavioral regulation in four societies: the United States, Taiwan, South Korea, and China. Directly assessed individual behavioral regulation(Head–Toes–Knees–Shoulders, HTKS), teacher-rated classroom behavioral regulation (Child Behavior Rating Scale, CBRS) and a battery of school readiness assessments (mathematics, vocabulary, and early literacy) were used with...
Algae can be used in a variety of wastewater systems to capture nutrients while fixing carbon dioxide from the atmosphere. I conducted field trials at three locations in Oregon with both corn and potato crops to assess the agronomic value and environmental impact of using the resulting algal biomass as...
Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...
Worldwide, in recent years capture fisheries targeting lower-trophic level forage fish and euphausiid crustaceans have been substantial (∼20 million metric tons [MT] annually). Landings of forage species are projected to increase in the future, and this harvest may affect marine ecosystems and predator-prey interactions by removal or redistribution of biomass...
We examined 480 dissertations on the use of technology in mathematics education and developed a Quality Framework (QF) that provided structure to consistently define and measure quality. Dissertation studies earned an average of 64.4% of the possible quality points across all methodology types compared to studies in journals that averaged...
What is the nature of evolutionary divergence of the jaw skeleton within the genus Oncorhynchus? How can two associated bones evolve new shapes and still maintain functional integration? Here, we introduce and test a ‘concordance’ hypothesis, in which an extraordinary matching of the evolutionary shape changes of the dentary and...
