    Abstract : The objective of the thesis was to explore the potential of diatoms (Bacillariophyceae) as indicators of Holocene climate and environmental change in northern Sweden (Abisko region, 68°21'N, 18°49'E). A modern surface-sediment calibration set including 100 lakes was developed and lake-water pH, sedimentary organic content (assessed by loss-on-ignition) and temperature were identified as most powerful environmental variables explaining the variance within the diatom assemblages.

  4. 2. Constructing Workers of Migrant Background : A study of class and nation myths in trade union practice

    Abstract : How do trade unions represent workers of migrant background? How are factors that affect the quality of life of workers of migrant background, made sense of and responded to by trade unions trying to reverse declining trade union membership numbers? This thesis takes a qualitative approach and utilises discursive constructions as a semiotic entry point into the social practices of trade unions and their responses to workers of migrant background. Combining semiotic theory of Roland Barthes and Stuart Hall with critical discourse theory of Norman Fairclough, trade union work is conceptualised as a social practice that comprises both semiotic and non-semiotic elements.
