The Evolution of Clinical Practice and Supervision in the United States

Clinical practice in teacher education has evolved from an apprenticeship model to one that finds it more intertwined with collaborative arrangements with partnering public schools. We look at how this evolution has had a major impact on the effectiveness of how teachers are prepared in an ever more complex society. We also describe how instructional supervision has been intertwined with clinical practice throughout the decades

A New Pathway for the Preparation of Highly Qualified Teachers: The Master of Arts in Teaching (MAT)

This article reports on the development and initial implementation of a Master of Arts in Teaching (MAT) degree, an accelerated graduate program that encourages and scaffolds individuals with existing disciplinary expertise in entering the teaching profession. First, the context for developing the program is outlined. Next, the unique structure of the 15-month program, which consists of three blocks, is described. Expectations about students are then shared, quality control features of the program are highlighted, and the lessons we learned about program development and implementation are detailed. Finally, thoughts about the future of this program and others of its type are shared based upon our experience

Managing Grassy Woodlands: Balancing Production and Conservation of Resources

Eastern Australian eucalypt woodlands are important agricultural areas that have been widely modified during two centuries of European-style use. Despite this they contain important natural resources including significant biodiversity. Long term sustainability of production depends on maintaining resources and management must be for both production and conservation. A research program on four properties in south east Queensland showed the properties were in generally good condition although all had some problems, and has highlighted a number of significant costs and barriers to adopting a more balanced approach to production and conservation

Food relations and production of cutthroat trout, Salmo clarki clarki Richardson, in an experimental stream

Production, food consumption and food habits by groups of small, mixed and large sizes of cutthroat trout were studied in enriched and unenriched sections of the Berry Creek Experimental Stream, Oregon State University. Continuous introduction of sucrose and urea to portions of the stream resulted in heavy growth of Sphaerotilus natans which supported large biomasses of benthic insects. Production was estimated from monthly changes of biomass. Measurements of growth rates of experimental fish and the relationship between rates of growth and rates of food consumption of fish held in aquaria made estimates of food consumption by the stream fish possible. Analyses were made of the stomach contents of trout removed monthly from the experimental sections. The seasonal contribution to trout food consumption by the important food groups was estimated. Measurements of benthic biomass showed that insects especially midge larvae, benefited greatly from the Sphaerotilus in the enriched sections but organic drift did not increase markedly as a result of enrichment. In both enriched and unenriched sections trout production and food consumption values were highest for small trout, intermediate for mixed sizes and lowest for large trout. Production and food consumption by all size groups of trout increased greatly as a result of enrichment

Production and behavioral interactions of salmonids in an experimental stream

The behavior of two species of stream salmonids, juvenile coho salmon, Oncorhynchus kisutch (Walbaurn) and cutthroat trout, Salmo clarki clarki Richardson, was studied in terms of the time spent by individual fish in carrying out various activities. Studies were conducted from June 1968, through May 1969, at Berry Creek, a small woodland stream located approximately ten miles north of Corvallis, Oregon. A 1500 foot section of the stream was brought under complete flow control for experimental purposes by a concrete diversion dam and a bypass channel. Water flow into the experimental section was controlled by a large gate valve at the dam. The lower part of the controlled section was divided into experimental sections that were separated by inclined-screen fish traps. The Berry Creek Experimental Stream Laboratory is maintained as a field research station by the Department of Fisheries and Wildlife, Oregon State University. Behavioral observations were made from an observation booth located in an experimental section of Berry Creek. Time-budget analyses derived from observational data were used to evaluate the effects on production of the interaction between individual salmon stocked at different densities in separate stream sections and the interaction among populations comprising both species stocked separately and together at similar densities in different sections of the stream. The growth rates of juvenile coho salmon stocked during June and July 1968, at different biomasses in five of the experimental sections generally declined with increases of salmon biomass. Downstream movement and mean percentages of time spent in agonistic behavior by individual salmon increased with increases in biomass. Higher values of production and mean biomass were generally recorded for an experimental group comprising salmon and trout than for single species groups. Several of the trout on occasion occupied the riffle area of the observation section, whereas, coho salmon remained in the pool throughout the experiment. The use of the riffle area by the trout may have resulted in more efficient utilization of space and food and may explain, in part, the differences in production between the trout-salmon group and the single species group. The growth and location in the stream section of an individual trout or salmon appeared to depend on the fish's position in the integrated social structure. Fish of high social position benefitted in terms of increased amounts of feeding time, decreased activity and decreased agonistic behavior as compared with fish of lower social position. The effect of intraspecific interaction among salmon appeared to be greatest at those stocking densities which resulted in a decline of growth rate from the growth rates that were associated with the highest values of production. This interaction appeared to lead to a compromise between energy expenditures for agonistic behavior and efficient metabolism that resulted in stock densities between two and three grams/meter2 of section area

Evidence for an evolutionarily conserved interaction between cell wall biosynthesis and flowering in maize and sorghum

BACKGROUND: Factors that affect flowering vary among different plant species, and in the grasses in particular the exact mechanism behind this transition is not fully understood. The brown midrib (bm) mutants of maize (Zea mays L.), which have altered cell wall composition, have different flowering dynamics compared to their wild-type counterparts. This is indicative of a link between cell wall biogenesis and flowering. In order to test whether this relationship also exists in other grasses, the flowering dynamics in sorghum (Sorghum bicolor (L.) Moench) were investigated. Sorghum is evolutionarily closely related to maize, and a set of brown midrib (bmr) mutants similar to the maize bm mutants is available, making sorghum a suitable choice for study in this context. RESULTS: We compared the flowering time (time to half-bloom) of several different bmr sorghum lines and their wild-type counterparts. This revealed that the relationship between cell wall composition and flowering was conserved in sorghum. Specifically, the mutant bmr7 flowered significantly earlier than the corresponding wild-type control, whereas the mutants bmr2, bmr4, bmr6, bmr12, and bmr19 flowered later than their wild-type controls. CONCLUSION: The change in flowering dynamics in several of the brown midrib sorghum lines provides evidence for an evolutionarily conserved mechanism that links cell wall biosynthesis to flowering dynamics. The availability of the sorghum bmr mutants expands the germplasm available to investigate this relationship in further detail

Does a neutral thermal sensation determine thermal comfort?

The neutral thermal sensation (neither cold, nor hot) is widely used through the application of the ASHRAE seven-point thermal sensation scale to assess thermal comfort. This study investigated the application of the neutral thermal sensation and it questions the reliability of any study that solely relies on neutral thermal sensation. Although thermal-neutrality has already been questioned, still most thermal comfort studies only use this measure to assess thermal comfort of the occupants. In this study, the connection of the occupant’s thermal comfort with thermal-neutrality was investigated in two separate contexts of Norwegian and British offices. Overall, the thermal environment of four office buildings was evaluated and 313 responses (three times a day) to thermal sensation, thermal preference, comfort, and satisfaction were recorded. The results suggested that 36% of the occupants did not want to feel neutral and they considered thermal sensations other than neutral as their comfort condition. Also, in order to feel comfortable, respondents reported wanting to feel different thermal sensations at different times of the day suggesting that occupant desire for thermal comfort conditions may not be as steady as anticipated. This study recommends that other measures are required to assess human thermal comfort, such as thermal preference

A 4.8- and 8.6-GHz Survey of the Large Magellanic Cloud: I The Images

Detailed 4.8- and 8.6-GHz radio images of the entire Large Magellanic Cloud with half-power beamwidths of 33" at 4.8 GHz and 20" at 8.6 GHz have been obtained using the Australia Telescope Compact Array. A total of 7085 mosaic positions were used to cover an area of 6 degrees on a side. Full polarimetric observations were made. These images have sufficient spatial resolution (~8 and 5 pc, respectively) and sensitivity (3-sigma of 1 mJy/beam) to identify most of the individual SNRs and H II regions and also, in combination with available data from the Parkes 64-m telescope, the structure of the smooth emission in that galaxy. In addition, limited data using the sixth antenna at 4.5 to 6-km baselines are available to distinguish bright point sources (<3 and 2 arcsec, respectively) and to help estimate sizes of individual sources smaller than the resolution of the full survey. The resultant database will be valuable for statistical studies and comparisons with x-ray, optical and infrared surveys of the LMC with similar resolution.Comment: 28 pages, 10 figures, 2 tables, accepted for publication in the Feb 2005 A

Efficacy of compost amended biofiltration swales as green stormwater infrastructure for treatment of toxicants in Salish Sea road run-off

Biofiltration swales, or bioswales, use vegetated soil substrates to filter contaminants from stormwater, decrease sediment load, and reduce erosion. Following a storm, runoff moves slowly through the swale at a shallow depth. While stormwater is retained in the bioswales, pollutants are removed by the combined effects of filtration, infiltration, settling, and biotransformation. The system currently being evaluated at the Washington State University (WSU) Puyallup Research and Extension Center (PREC) uses compost to further enhance the ability of bioswales to remove toxicants. WSDOT has created guidelines for constructing compost amended biofiltration swales (CABS) and implemented a field test for CABS along Washington State Route (SR) 518 in 2009. As part of an ongoing study, influent and effluent samples are currently being collected at the field site during storm events and tested for metals, PAHs, pesticides, phthalates, and unknowns (LC-QTOF). Acute toxicity and sub-lethal effects of stormwater were also measured using zebrafish (Danio rerio) bioassays. Along with researchers from University of Washington (UW) we created a laboratory model for CABS at the WSU PREC to verify field test results in a controlled setting and identify ways that the WSDOT design could be improved. This system is exposed to highway runoff from a previously studied high volume source off SR 520 and tested at different flow rates, swale lengths, and slope gradients. Paired chemistry and toxicology data show how stormwater treatment by CABS differ from traditional soil biofiltration methods. Results presented at Salish Sea show how zebrafish developmental biology is affected by stormwater treatments and how CABS design impacts toxicant treatment efficacy
