    Författare :Lotta Dessen Jankell; Inger Eriksson; Patrik Johansson; Elin Sæther; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; systems thinking; geography teaching; system geographical knowing; system modelling; education for sustainable development; connection web models; system changes; learning activity; practice theory; learning models; geography didactics; systemtänkande; sambandsvävar; geografiundervisning; systemgeografiskt kunnande; systemmodeller; klimatförändringar; hållbar utveckling; ämnesdidaktik med inriktning mot de samhällsvetenskapliga ämnenas didaktik; Teaching and Learning with Specialisation in the Social Sciences Education;

    Sammanfattning : This doctoral thesis is concerned with how upper secondary students in Sweden develop system geographical knowing through Geography teaching, where complex issues such as climate change are dealt with. In many countries, these issues are particularly relevant for the school subject of Geography since the subject is responsible for issues that involve system changes. LÄS MER

  5. 4. Dynamic Queries

    Författare :Christopher Ahlberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Dynamic queries is an approach to database querying, information exploration, and information retrieval. Building on principles of direct manipulation, dynamic queries utilizes visualizations and graphical query devices to allow users to visually explore, browse, and query large datasets. LÄS MER

  7. 5. The dynamic microfilament system : cellular organization of actin and profilin and their association with cell signalling

    Författare :Lucie Hájková; Karl-Eric Magnusson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : Active shape changes and movement of whole cells, and translocations within cells are essential to life. For instance, during embryogenesis cell migration is a central theme. Wound healing depends on increased and directed motile activity of several cell types. LÄS MER
