    • Soil water chemistry in forest soils over 20years was studied at nine sites in southern Sweden. The aim was to investigate the recovery from acidification and the influence of strong sea salt episodes that occur in the region. All sites but one showed signs of recovery from acidification along with the reduced sulphur deposition, but the recovery progress was slow and the soil water was in most cases still highly acidic at the end of the period. In several cases the recovery was delayed by episodes of sea salt deposition, leading to transient acidification. The less marked decrease of sulphur concentrations in soil water than of sulphur deposition, highlighted the importance of sulphur adsorption/desorption in the acidification and recovery process. Nitrogen retention capacity was exceeded on one site, leading to nitrate leaching and extremely low pH. Storm fellings on two sites in the end of the period led to effects similar to those of regeneration fellings. It was concluded that the soils in the region are in an early stage of recovery. The future progress of recovery strongly depends on future nitrogen retention of forest soils and the frequency of sea salt episodes.

  • Behind the very notes: Playful creativity in coping with notation

    • This study explores musicians' ways of taking and giving meaning to notation in Western tonal music. From a socio-cultural theoretical perspective relations between traditions and individuals were especially accounted for. Linked to this perspective the method for the study was developed. Experienced pianists commented on well-prepared performances of one freely chosen work, and prescribed pieces written without markings on expression. In the interpretations of the prescribed pieces a great variety of alternate implicit musical meaning was explored, even by musicians who mainly aimed at reproducing edited expression in their freely chose works. The conclusions was drawn that simple pieces written without markings on expression might serve as pedagogical tools in instrumental training. In a playful way students might develop their musical judgment and understanding of musical practice.
