    Harmonic maps from degenerating Riemann surfaces

    Get PDF
    We study harmonic maps from degenerating Riemann surfaces with uniformly bounded energy and show the so-called generalized energy identity. We find conditions that are both necessary and sufficient for the compactness in W1,2W^{1,2} and C0C^{0} modulo bubbles of sequences of such maps.Comment: 27 page

    Oralism: a sign of the times? The contest for deaf communication in education provision in late nineteenth-century Scotland

    Get PDF
    Disability history is a diverse field. In focussing upon children within deaf education in late nineteenth-century Scotland, this essay reflects some of that diversity. In 1880, the International Congress on the Education of the Deaf in Milan stipulated that speech should have ‘preference’ over signs in the education of deaf children. The mode of achieving this, however, effectively banned sign language. Endeavours to teach deaf children to articulate were not new, but this decision placed pressures on deaf institutions to favour the oral system of deaf communication over other methods. In Scotland efforts were made to adopt oralism, and yet educators were faced with the reality that this was not good educational practice for most pupils. This article will consider responses of Scottish educators of deaf children from the 1870s until the beginning of the twentieth century

    Electron microscopic demonstration of centrifugal nerve fibers in the human optic nerve

    Electron microscopic views of centrifugal nerve fibers in the optic nerve stump of a 56-year-old man are presented. These nerve fibers had survived for 16 days after removal of the corresponding eyeball and exhibited terminal swellings pointing in a distal direction and indicating axoplasmic flow towards the removed eye. The centrifugal nerves in this adult lack any evidence of attempted regeneration that has earlier been observed under similar conditions in the optic nerve stump of a child. Zentrifugale (antidrome, efferente) Nervenfasern sind hier zum ersten Mal mit dem Elektronenmikroskop im menschlichen Sehnerven dargestellt worden. Diese Nervenfasern wurden in dem Sehnervenstumpf eines 56jährigen Mannes 16 Tage nach der Entfernung des dazugehörigen Auges gefunden. Endschwellungen dieser Nervenfasern waren distal ausgerichtet und deuteten damit einen Axoplasmafluß in Richtung des entfernten Auges an. Während deutliche Regenerationsversuche an den distalen Enden unterbrochener zentrifugaler Nervenfasern im Sehnervenstumpf eines Kindes früher beobachtet worden sind, fanden sich im Sehnerven dieses Erwachsenen keinerlei Zeichen von Regeneration der zentrifugalen Fasern.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47369/1/417_2004_Article_BF00414787.pd

    Managing agency for athletic performance: a discursive approach to the zone

    Get PDF
    This paper provides a discursive perspective on a concept used within sport psychology, in both its academic and practical discourse, namely 'the zone.' This extraordinary state is one of exceptional peak performance whereby an athlete claims to perform effortlessly, automatically, and successfully. The focus of this paper is the use of the zone as a discursive resource in accounting for successful performance. Through the examination of two televised accounts of performance by elite athletes, I argue that the zone can be used as a way of managing agency for a performance for diluting or softening accounts of success, or as a way of claiming success was probable when failing due to injury. The paper proposes a number of rhetorical contrasts that are evident in the discursive deployment of the zon
