The purpose of this qualitative research study was to describe the experiences of secondary teachers who were actively involved in positions of teacher leadership in their schools and to discover the meaning that leadership activities had for them in their work. The informal teacher leaders performed their leadership functions in...
Genetic differences between early and late forms of
Alaskan chinook salmon (Oncorhynchus tshawytscha) were
identified using two genetic approaches: mitochondrial
DNA (mtDNA) analysis and protein electrophoresis. The
study populations consisted of early- and late-run chinook
salmon in each of the Kenai and Kasilof rivers in Alaska,
and a single population...
Enumerative combinatorics is an area of mathematics that is both highly accessible for students and widely applicable to other sciences and areas of mathematics (Kapur, 1970; Lockwood, Wasserman, & Tillema, 2020). One important class of problems in combinatorics is combinatorial proofs of binomial identities, which is a type of proof...
Accumulating human impacts on freshwater ecosystems have created a biodiversity crisis for freshwater fishes while conservation efficacy remains hampered by the Linnaean shortfall, the ignorance of many species that have yet to be discovered and described. The past discovery of most freshwater fish species was simply a matter of collecting...
The purpose of this study was to: (a) determine the design features of the physical learning environment that support and enhance collaborative, project-based learning at the community college level; and (b) to gain an understanding of the rationale for the selection of the features. The characteristics of the physical environment...
This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...
