    Lifelong learning and partnerships: rethinking the boundaries of the university in the digital age

    Get PDF
    Higher education (HE) in Scotland has some very specific characteristics: a relatively small number of HE institutions (HEIs), nineteen at the time of writing; a strong college sector, which makes a significant contribution to the provision of HE; an all through credit and qualifications framework, designed to support transitions between different parts of the education system and through the lifecourse; no fees for full-time HE and more than fifteen years of policy initiatives aimed at (WP). Despite all this, unequal access between different socio-economic groups has remained stubbornly persistent. Moreover, the numbers of mature and part-time students in both the university and college sectors have declined. This paper looks at some of the evidence from the Opening Educational Practices in Scotland project, which is exploring the interface between open education and WP. In the context of the widespread availability of digital devices and the rapid increase in free, open online resources, are there new strategies to promote WP and lifelong learning

    Competition between Spiral-Defect Chaos and Rolls in Rayleigh-Benard Convection

    Full text link
    We present experimental results for pattern formation in Rayleigh-Benard convection of a fluid with a Prandtl number, Pr~ 4. We find that the spiral-defect-chaos (SDC) attractor which exists for Pr~1 has become unstable. Gradually increasing the temperature difference from below to well above its critical value no longer leads to SDC. A sudden jump of temperature difference from below to above onset causes convection to grow from thermal fluctuations and does yield SDC. However, the SDC is a transient; it coarsens and forms a single cell-filling spiral which then drifts toward the cell wall and disappears.Comment: 9 pages(RevTeX), 5 jpg figures, To appear as Rapid Communication in PR
