    Learning from experience: the case study of a primary school

    This thesis is a case study about learning from experience in a primary school. The enquiry applies a psychoanalytic idea in an educational context. The focus arose from Bion’s idea: ‘Container-contained’ (Bion, 1962) which proposes that the capacity to think is emotionally rooted in our first relationship, which informs the qualities of our subsequent ‘learning relationships’ (Youell, 2006). Within a psychosocial, interpretivist framework, research questions ask: How does the learning that children bring to school affect their relationships and learning? How can school provide flexible-enough containment for thinking and learning from experience? What have I learnt about learning from experience? As a researcher/mentor, an interpretation of Bick’s (1964) clinical observational method was deployed to generate data, including written-up observations of four case study children who communicated their stories of everyday events in school during mentoring sessions. An auto/biographical approach complementarily composed part of the methodological bricolage. The inductive method supported evolution of a relational approach to mentoring, permitting reflexive interrogation of the observational texts. Interviews with teachers and parents added a biographical dimension. Mentoring took place during half-hour, weekly, individual mentoring sessions with children over two terms. Findings confirmed that children brought early experiences of learning to school which affected relationships and posed barriers to learning. The research method provided a subjective tool for making unconscious qualities of relationship in the transference and countertransference between researcher, children and adults at an institutional level, explicit. RefIexive interrogation illumined the interrelationship between researcher and children’s learning. Findings showed a need for flexible boundaries for supporting children’s self-efficacy and personal agency, and teacher’s learning about learning, when school is seen as a ‘container’. Findings confirmed the need for time and space for children and adults to reflect on experience in school, towards fostering emotional well-being and the capacity to think and learn

    Investigation of environmental effects on coatings for thermal control

    Accomplishments made during study of coatings are reported. Development of structure/property theory for selecting most appropriate pigments for space vehicle paints is discussed along with improvements made in zinc-oxide pigmented potassium silicate paint

    Development of a space stable thermal control coatings for use in large space vehicles

    The preparation and evaluation of zinc orthotitanate and of several new pigments and the environmental testing and evaluation of these pigments and of coatings made from them constitute the bulk of the work accomplished. New pigments were prepared and EPR spectra of pigments and their precursor compounds studied. Results of extensive testing of commercially-available, strippable, protective coatings are reported; Owens-Illinois 650 glass resin has been stabilized against progressive mechanical failures; and definite improvements have been noted. A zinc oxide pigmented lithium silicate paint has demonstrated very good ultraviolet stability

    The evaluation and environmental testing of zinc orthotitanate pigments for use as space stable thermal control coatings on large space vehicles are discussed. Electron paramagnetic resonance spectra of the pigments and their precursor compounds are examined. A continuing study of the spectral intensity of mercury-argon and mercury-xenon sources in reported. Results of long term environmental testing of commercially available, strippable, protective coatings are discussed

    Clinical Characterization of Alzheimer's Disease: Reliability of 'Age at Onset' and a New Descriptor, 'Age at Shift'

    To determine the interrater reliability of clinical descriptors for Alzheimer's disease (AD), we assessed the degree of agree ment among four clinicians who rated 21 patients during a longitudinal study. Despite variability in response patterns, degree of agreement for determining age at onset of dementia was statistically significant (P < 0.005). We also found significant agreement (P < 0.0001) among three clinicians for the clinical descriptor, "age at shift" from questionable to probable AD, according to the National Institutes of Health Consensus Criteria. These data demonstrate that both retro spective and prospective descriptors can be reliably determined in the clinical assessment of AD.

    Age and Growth of Scotia Sea Icefish, Chaenocephalus aceratus, From the South Shetland Islands

    Get PDF
    Samples of Chaenocephalus aceratus (Lönnberg) were collected during a trawl survey carried out around the South Shetland Islands in January–February 2002. Fish were caught by commercial bottom trawl fishing down to 500 m depth, using a stratified randomized sampling design. As observed in other recent surveys within the same area, C. aceratus represented one of the predominant species. Overall, 357 specimens ranging from 13 and 67 cm (TL) were selected for the present study. Ages were estimated by counting annuli present in the sagittal otoliths, exposed by grinding and polishing along their sagittal plane. To estimate the precision of age data, we compared blind readings by readers from different institutions. The age range was 1–17 years for females and 1–15 years for males. Von Bertalanffy growth curves were fitted to the estimated age-length data for each sex. The estimated values of asymptotic length L∞ (cm) and K (year-1) were respectively 79.8 and 0.07 for females and 60.0 and 0.09 for males. The growth performance index ranged between 2 and 2.5, similar to that reported in other icefish. Sexual maturity was attained by females and males at about 10 and 9 years old respectively, at about 60% of their maximum estimated age. These results are compared with age and growth data available in the literature for C. aceratus, and discussed in the light of recent commercial exploitation
