ABSTRACT Increasing strains on self-sufficiency within the block of East European command economies resulted in the dramatic decision to change over to an economic system largely based on market forces. The painfulness of the ensuing transformation process will be mitigated somewhat by supportive economic policies of the West, including the European Community which is itself aiming at complete economic integration by the end of 1992. The consequences for the developing countries of these far-reaching policy changes in East and West are likely to be negative, at least in the immediate future. This is true for the volume of development assistance given by East and West, as well as for the export prospects of developing countries. Favourable effects might at best be expected in the longer run.  相似文献

The records of fabulous stones associated with birds are here examined systematically for the first time. Some were purported to be obtained from within the bird and others obtained from the nest. Zahir mora, the Adjutant Bird Stone, was used against snake bite, whilst Alectorius (the Cock Stone), Aetites (the Eagle Stone) and Vulturis (the Vulture Stone) shared a multiplicity of medicinal applications. Quirin (the Hoopoe Stone), Chloritis (the Wagtail Stone) and Corvina (the Crow Stone) supposedly possessed occult powers. The Penguin Stone, Ostrich Stone and Pigeon Stone were probably gastroliths.  相似文献
