There has been a rapid increase in technological advances in the biological sciences that has contributed to an increase in societal issues that require attention from both scientists and citizens. Consequently, there is a need for the development of biologically literate citizens who have the ability to use their knowledge...
Courtship and copulation behaviors in Drosophila melanogaster males are regulated by sex-specific products from the gene fruitless (fru). Male-specific FRU proteins (FRU[superscript M]) are putative transcription factors of the BTB-ZnF family that likely act by controlling development and maintenance of the neural circuitry used during male sexual behavior. However, which...
This multiple case study explores issues of equity in science education through an examination of how teachers' reasoning patterns compare with students' reasoning patterns during inquiry-based lessons. It also examines the ways in which teachers utilize students' cultural and linguistic resources, or funds of knowledge, during inquiry-based lessons and the...
A steady gas convection model of heat transfer to a horizontal
cylinder immersed in a gas fluidized bed is presented. Contributions due to flow within
attached bubbles as well as the interstitial voids are
included. The interstitial flow is approximated as flow within a series
of double cusped channels and...
An oscillating plasma glow discharge detector for gas
chromatography is used to obtain fingerprint information
about an analyte by combining both the average cell
current and oscillation frequency signals. Five homologs
each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones and
aldehydes are studied. Although triplicate determinations
had some scatter due to...
The Endangered Species Act of 1973 (ESA) is considered by many to be among the most powerful and most contentious environmental laws in the United States. Persistent challenges to the Act’s implementation make reaching conservation goals problematic. Most notably, the very nature of the law—providing protections for species already at...
Estimating the hydraulic conductivity of earth materials is important for many water resource modeling efforts, including predicting the transport of pollutants in ground water, computing surface runoff for flood control, and computing water budgets. This research implicitly used topography, soil, and climate data to estimate plausible continuous hydraulic conductivity values...
This qualitative study investigated the sibling relationship as it was described through the voices of the children. Ten sibling dyads (brother-sister or brother-brother) involved in family treatment following the discovery of sibling incest were interviewed. Participants in this study were participants in an outpatient clinic in the Northwest during the...
The purpose of this case study was to examine a third-grade teacher’s effective use of mathematical discourse in the classroom setting. The study offers insights into the following research questions: 1) How does a teacher’s engagement in mathematical discourse communities influence her practice and self-efficacy as a mathematics educator? 2)...
The distribution of adult Pacific herring (Clupea harengue
pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by
depth and geographic area over 24 successive months during 1973-75.
From June through September, schools concentrated at 5- to 37-m
depths where zooplankton was abundant, and moderate currents were
present in a...
