This dissertation consists of a set of three manuscripts exploring features of effective professional development (PD) for science teacher educators. Literature about context-specific PD for science teacher educators is sparse. The first manuscript, a literature review, outlines theoretical lenses through which PD can be understood, the features of effective PD,...
Biological interrelationships between the ambrosia beetle
Xyleborus dispar (F.) (Coleoptera:Scolytidae) with its symbiotic
fungus, Ambrosiella hartigii Batra (Fungi Imperfecti) were investigated
in western Oregon.
Postdiapause adults of X. dispar collected in March through
June with rotary nets, and excised from overwintered and newly
attacked host material, produced a single generation...
This study examines how three measures of child health: overall health status, access to health insurance and dental checkup status, predict the likelihood of a child experiencing higher number of absences in children eligible to attend Head Start, and how that association is influenced by the presence of a depressed...
Understanding the movement behavior and foraging strategies of individuals across multiple spatial and temporal scales is essential not only for understanding the biological requirements of individuals but also for linking individual strategies to population level effects. Glacial fjords scattered throughout south-central and southeastern Alaska host some of the largest seasonal...
Aerosol concentrations and 3-D winds were measured from 9 to 25 September 2007, above a pine forest in California. The measurements were combined using the eddy covariance (EC) technique to determine aerosol eddy fluxes as a function of particle diameter within the accumulation mode size range (0.25 μm≤D[subscript]p≤1 μm here)....
