    Dr. Rita Colwell, microbiologist at the University of Maryland, Paul S. Tabor, microbiologist at the University of Maryland, Dr. Jack Colwell, NBS Heat Division physicist, and Meyer Waxman, NBS Heat Division physicist at University of Maryland Laboratory, with a deep-ocean sampler. From Dimensions, April 1977. This image is part of the Deep Ocean Sampler collection. In the late 1970s the National Bureau of Standards designed an ocean sampling apparatus for use at depths of 10,000 meters, where the pressure was about 1,000 times atmospheric pressure. The deep ocean sampler allowed for pre-pressurizing a sterilized interior sampling chamber, capturing a sample at the required depth, and maintaining the sample at its deep-water pressure while allowing scientists to study the enclosed microorganisms in the laboratory

    Photocopy of a memorandum from Jack Davis, co-director of North Texas Institute for Educators on the Visual Arts to Will May, Ralph Culp, Jan Newcomer, and Rick Sale. In the memo, Davis attached the grant proposal and thanks them for their assistance. In his handwritten note, "P.S. I thought you'd be interested in the untouched letter for Richard Colwell which I received today." Included with the memo is the letter from Richard Colwell, Professor of Music at West California. The letter mentions that the National Center for Research in Arts Education is over and has some ideas for a cooperative plan and would like Davis to share with him their proposal to look over the institution and incorporate similar ideas

    Reflective teaching in early education

    No full text
    About the BookReflective Teaching in Early Education is the definitive textbook for reflective professionals in early education, drawing on the experience of the author team and the latest research, including the Teaching and Learning Research Programme (TLRP) findings. It offers extensive support for both undergraduate and postgraduate students and career-long professionalism for early years practitioners working in pre-schools, child care settings and the first years of primary schools.Written by a collaborative author team of leading early years educationalists and practitioners led by Jennifer Colwell, Reflective Teaching in Early Education offers two levels of support:- comprehensive, practical guidance for practitioner success with a focus on key issues such as building relationships, communication, behaviour, inclusion, curriculum planning and learning, and teaching strategies; and- evidence-informed 'principles' and 'concepts' to aid understanding of the theories informing practice, offering ways to develop deeper understanding of early years practice in early childhood education and care.Reflective activities, case studies, diagrams and figures, end-of-chapter summaries and research briefings are provided throughout.This book, along with the companion reader and associated website, draw upon the work of Andrew Pollard, former Director of the TLRP, and the work of many years of accumulated understanding of generations of early years practitioners, primary school teachers and educationalists.The team includes:Early Years Educationalists: Jennifer Colwell (University of Brighton, UK) | Helen Beaumont (Early Years Advisor, Brighton, UK) | Helen Bradford and Holly Linklater (University of Cambridge, UK) | Julie Canavan, Denise Kingston and Sue Lynch (University of Brighton, UK) | Catriona McDonald and Sheila Nutkins (University of Aberdeen, UK) | Tim Waller (Anglia Ruskin University, UK) Early Years Practitioners: Emma Cook, Sarah Ottwell and Chris Randall (Oneworld Nursery, Brighton, UK) with staff from One World Nursery and Phoenix Nursery (Brighton, UK)Readings for Reflective Teaching in Early Education directly compliments and extends the chapters of this book. It has been designed to provide convenient access to key texts, working as a compact and portable library.The associated website, www.reflectiveteaching.co.uk offers supplementary resources including reflective activities, research briefings and advice on further readings. It also features a glossary of educational terms, links to useful websites and showcases examples of excellent research and practice.This book forms part of the Reflective Teaching series, edited by Andrew Pollard and Amy Pollard, offering support for reflective practice in early, primary, secondary, further, vocational, university and adult sectors of education.

    Waves in Cassini UVIS stellar occultations. 2. The C ring

    International audienceWe performed a complete wavelet analysis of Saturn's C ring on 62 stellar occultation profiles. These profiles were obtained by Cassini's Ultraviolet Imaging Spectrograph High Speed Photometer. We used a WWZ wavelet power transform to analyze them. With a co-adding process, we found evidence of 40 wavelike structures, 18 of which are reported here for the first time. Seventeen of these appear to be propagating waves (wavelength changing systematically with distance from Saturn). The longest new wavetrain in the C ring is a 52-km-long wave in a plateau at 86,397 km. We produced a complete map of resonances with external satellites and possible structures rotating with Saturn's rotation period up to the eighth order, allowing us to associate a previously observed wave with the Atlas 2:1 inner Lindblad resonance (ILR) and newly detected waves with the Mimas 6:2 ILR and the Pandora 4:2 ILR. We derived surface mass densities and mass extinction coefficients, finding r = 0.22(±0.03) g cm À2 for the Atlas 2:1 ILR, r = 1.31(±0.20) g cm À2 for the Mimas 6:2 ILR, and r = 1.42(±0.21) g cm À2 for the Pandora 4:2 ILR. We determined a range of mass extinction coefficients (j = s/r) for the waves associated with resonances with j = 0.13 (±0.03) to 0.28(±0.06) cm 2 g À1 , where s is the optical depth. These values are higher than the reported values for the A ring (0.01-0.02 cm 2 g À1) and the Cassini Division (0.07-0.12 cm 2 g À1 from Colwell et al. (Colwell, J.E., Cooney, J.H., Esposito, L.W., Sremčević , M. [2009]. Icarus 200, 574-580)). We also note that the mass extinction coefficient is probably not constant across the C ring (in contrast to the A ring and the Cassini Division): it is systematically higher in the plateaus than elsewhere, suggesting smaller particles in the plateaus. We present the results of our analysis of these waves in the C ring and estimate the mass of the C ring to be between3.7(±0.9) Â 10 16 kg and 7.9(±2.0) Â 10 16 kg (equivalent to an icy satellite of radius between 28.0(±2.3) km and 36.2(±3.0) km with a density of 400 kg m À3 , close to that of Pan or Atlas). Using the ring viscosity derived from the wave damping length, we also estimate the vertical thickness of the C ring between 1.9(±0.4) m and 5.6(±1.4) m, comparable to the vertical thickness of the Cassini Division
