  1. 6. Den delade skolan : segregationsprocesser i det svenska skolsystemet

    Författare :Anders Trumberg; Mats Lundmark; Roger Andersson; Bo Malmberg; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Segregation; Integration; School choice; Pupil; GIS; Voroni; Bourdieu; Socioeconomic; Ethnic; Time geography; Spatial capital; Örebro; Networks; Family; Middle sized cities; Arena; School reforms.; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Human geography; Kulturgeografi; Sociology; Sociologi; Social and Economic Geography; Kulturgeografi;

    Sammanfattning : In the beginning of the 1990s the responsibility for the compulsory schools shifted from the government to the local authorities, a freedom of choice was introduced, and several municipalities brought in a school voucher system. With these changes, the educational system in Sweden went from being one of the world’s most government dominated and unified, to one with a high level of freedom of choice. LÄS MER

  3. 7. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

    Författare :Kristina Blennow; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. LÄS MER

  4. 8. Estimating source area of pollen and pollen productivity in the cultural landscapes of southern Sweden - developing a palynological tool for quantifying past plant cover

    Författare :Anna Broström; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerial photographs; pollen productivity estimates; relevant source area of pollen; southern Sweden; quantitative landscape reconstruction; GIS; pollen dispersal; simulation model; Geology; physical geography; Geologi; fysisk geografi;

    Sammanfattning : Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. LÄS MER

  5. 9. Remote Sensing of Forest Decline in the Czech Republic

    Författare :Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Sammanfattning : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. LÄS MER

  7. 10. Planning for equitable emergency health care : Assessing the geography of ambulance supply and demand in Sweden

    Författare :Jacob Hassler; Vania Ceccato; Charles Branas; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emergency health care; spatial analysis; equity; policy; akutvård; rumslig analys; jämlikhet; policy; Urbana och regionala studier; Urban and Regional Studies;

    Sammanfattning : Providing high-quality health care to everyone who needs it is a central objective for theSwedish health care system. One way in which this goal is broadly pursued is by allocatingresources that maximize the geographical coverage of ambulances, aiming at reducingambulance response times as much as possible, for as many as possible.
