16. Trees and the environment : Possibilities and challenges in tree-ring research across spatial and temporal scales based on case studies in Sweden
Sammanfattning : The need to understand and quantify the magnitude and frequency of past and current environmental changes increased the demand for high-resolution proxy data across spatial and temporal scales. Due to their long lifespan and global distribution, trees provide a unique and continuous record of environmental variability. LÄS MER
17. Topological and Scaling Analysis of Geospatial Big Data
Sammanfattning : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. LÄS MER
18. Natural Hazards as Windows of Opportunity for Change : Character and Time Perspectives on Environmental Opportunities and Preparedness
Sammanfattning : In the aftermath of natural hazards, opportunities often arise for society to make changes that prevent future losses. These changes can also have environmental impacts, increase preparedness, and contribute to sustainable development. LÄS MER
19. Tecken av betydelse : En studie av dialog i ett multimodalt, teckenspråkigt tvåspråkigt NO-klassrum
Sammanfattning : Ett gemensamt meningsskapande i skolans naturvetenskapliga klassrum förutsätter en interaktion som i allt högre grad kommer att präglas av ett naturvetenskapligt språkbruk. Utvecklingen av ett naturvetenskapligt ämnesspråk innebär ofta en stor utmaning för flerspråkiga elever som lär sig naturvetenskap på sitt andraspråk och vars behov av stöttning därför är särskilt stort.

20. Home for future Earth lovers : Foundations of nature-connecting habitats for children
Sammanfattning : Modern childhood is increasingly segregated from nature. Yet, children’s nature experiences are first steps for sustainable futures. In this thesis, I research the foundations of habitats that can connect children to nature. I call them nature-connecting habitats. LÄS MER
