   Sammanfattning : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active fire detection; biome; multi-criteria; Sentinel-2; Landsat-8; burned area mapping; deep learning; semantic segmentation; machine learning.; aktiv branddetektering; biom; multikriterietillvägagångssätt; Sentinel-2; Landsat-8; kartläggning av bränt område; djupinlärning; semantisk segmentering; maskininlärningsmetoderna; Geoinformatik; Geoinformatics;

   Sammanfattning : Remote sensing data has great potential for wildfire detection and monitoring with enhanced spatial resolution and temporal coverage. Earth Observation satellites have been employed to systematically monitor fire activity over large regions in two ways: (i) to detect the location of actively burning spots (during the fire event), and (ii) to map the spatial extent of the burned scars (during or after the event).

4. 3. How social influence affects children’s witness reports

   Författare :Emma Roos Af Hjelmsäter; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children’s memory; social influence; omission and commission errors; source of influence; central and peripheral details.;

   Sammanfattning : Eyewitnesses to criminal events often discuss their experiences with each other. This can have serious consequences considering the fact that information received from others can have a detrimental effect on people’s memory reports. LÄS MER

5. 4. Children's memory reports: The effect of co-witness influence

   Författare :Emma Roos Af Hjelmsäter; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children’s memory; social influence; eyewitnesses; omission and commission errors;

   Sammanfattning : Co-witness discussion is relatively frequent, but misinformation in the form of information provided by other witnesses is an under-researched topic. The present thesis investigated how and to what extent children’s witness reports were influenced by information from a co-witness. LÄS MER
