    Local responses to changed circumstances: Coalmining in the market economy in Upper Silesia, Poland (1999)
    Springer
    GeoJournal 48 (1999), S. 279-290 
    Details
    ISSN: 1572-9893
    Keywords: coalmining ; communism ; local decision-making ; market economy ; Poland ; Upper Silesia

    Topics: Geography
    Notes: Abstract It is argued that the emphasis of much recent research into coalmining has been placed on international and national scale influences which affect coalfields as a whole; change at the intra-coalfield scale has received less attention. After providing a background to events in Poland during communism, attention focuses on developments since 1989, commencing with coalfield-wide influences. There follows an examination of the work of the state body Państwowa Agencja Węgla Kamiennego, which executes government policy at the local level, and whose membership is drawn from the coalfield region. This agency recommends the closure and amalgamation of mines, but otherwise rationalisation measures are left to the seven mining companies and the colliery managers. The restructuring which has been carried out is considered under five heads: organisational change within the collieries, employment, production and technical change, and ecological adjustment. While recognising the importance of the socioeconomic and political environment and geology, there is much evidence to suggest that intra-coalfield patterns are strongly determined by local decision-makers.

    Measurements of the skull and of some of the long bones of the muskrat (Ondatra zibethicus cinnamominus) (1934)
    New York, NY : Wiley-Blackwell
    Journal of Morphology 56 (1934), S. 203-212

    ISSN: 0362-2525

    Topics: Biology , Medicine
    Notes: The skull, mandible, and five pairs of long bones from the skeletons of 125 muskrats were weighed and measured. Each bone of the pairs of long bones was weighed and measured separately. Thirteen dimensions of the skull were determined.The long bones are slightly less variable in length than the skull dimensions. There is a rather wide range of variation in the thirteen dimensions of the skull, with the length and breadth of the skull less variable than the lengths of the long bones.The coefficients of correlation show that the weight of the skull is a good index to the weights of the long bones. The skull length has likewise high correlations with the lengths of the long bones and the longitudinal dimensions of the skull, with the exception of the palatine slits. The transverse diameters are not significantly correlated with the skull length.The long bones are asymmetrical in weight and length. They are longer more frequently on the left side and all except the tibia are heavier more frequently on the left side.
