1. Alternative Stable States in Size-Structured Communities : Patterns, Processes, and Mechanisms
Sammanfattning : Alternative stable states have been, based on theoretical findings, predicted to be common in ecological systems. Empirical data from a number of laboratory and natural studies strongly suggest that alternative stable states also occur in real populations, communities and ecosystems. LÄS MER
2. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes
Sammanfattning : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. LÄS MER
3. Earning, caring, and the quest for sustainable societies : Toward stable evolution?
Sammanfattning : This thesis studies changing conditions for earning and caring in Italy and Sweden, two cases out of a population of European welfare states facing similar challenges and processes of labor market liberalization affecting conditions for earning, but also for caring. Focus is on how such processes of change affect individual living conditions for earning and caring, as well as on how societies change as a result of changing individual living conditions. LÄS MER
4. Noise sensitivity and FK-type representations for Gaussian and stable processes
Sammanfattning : This thesis contains four papers on probability theory. Paper A concerns the question of whether the exclusion sensitivity and exclusion stability of a sequence of Boolean functions are monotone with respect to adding edges to the underlying sequence of graphs. LÄS MER
5. Nelson-type Limits for α-Stable Lévy Processes
Sammanfattning : Brownian motion has met growing interest in mathematics, physics and particularly in finance since it was introduced in the beginning of the twentieth century. Stochastic processes generalizing Brownian motion have influenced many research fields theoretically and practically. LÄS MER
