  1. 16. Trees and the environment : Possibilities and challenges in tree-ring research across spatial and temporal scales based on case studies in Sweden

    Författare :Eva Rocha; Steffen Holzkämper; Björn Gunnarson; Anders Moberg; Martin De Luis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree rings; Sweden; climate variability; environmental monitoring; ring width; maximum latewood density; stem radial increment; ED-XRF; light rings; Physical Geography; naturgeografi;

    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

  2. 17. Topological and Scaling Analysis of Geospatial Big Data

    Författare :Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

    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

  3. 18. Natural Hazards as Windows of Opportunity for Change : Character and Time Perspectives on Environmental Opportunities and Preparedness

    Författare :Åsa Davidsson; Magnus Johansson; Carl Bonander; Yvonne Andersson Sköld; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; window of opportunity; change; environment; natural hazard; preparedness; Risk and Environmental Studies; Risk- och miljöstudier;

    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

  4. 19. Tecken av betydelse : En studie av dialog i ett multimodalt, teckenspråkigt tvåspråkigt NO-klassrum

    Författare :Camilla Lindahl; Bengt-Olov Molander; Inger Lindberg; Anders Jakobsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Science education; multilingualism; sign language; multimodality; social semiotics; dialogic teaching; translanguaging; scaffolding; Naturvetenskapsämnenas didaktik; flerspråkighet; teckenspråk; multimodalitet; socialsemiotik; dialogisk undervisning; translanguaging; stöttning; Didactics; didaktik;

    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.

  5. 20. Home for future Earth lovers : Foundations of nature-connecting habitats for children

    Författare :Matteo Giusti; Stephan Barthel; Lars Marcus; Louise Chawla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human-nature connection; nature-connecting habitat; children; sustainability; human-nature relationship; Sustainability Science; vetenskap om hållbar utveckling;

    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
