   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Educational attainment; Educational enrollment; Trajectories; Socioeconomic integration; Migrants; Refugees; Sweden; Longitudinal data analyses; Register data; Educational registers; geografi med kulturgeografisk inriktning; Geography with Emphasis on Human Geography;

   Sammanfattning : Following the substantial influx of migrants to Sweden in recent decades, the socioeconomic integration processes of migrants have become a key focus for scholars and policymakers. In this thesis, I acknowledge the multifaceted role of education for both individuals and society, and aim to describe, explain, and examine the determinants and geographical manifestation of educational attainment and educational enrollment trajectories of adult migrants in Sweden, employing quantitative analyses and longitudinal register data.

3. 17. On Speciation in Birds – Genomic Signatures across Space and Time

   Författare :Martin Stervander; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colonization; islands; isolation; introgressive hybridization; sympatry; natural selection; bill morphology; coalescence-based analyses; DNA sequencing; birds; divergence; Speciation;

   Sammanfattning : The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. LÄS MER

4. 18. Integration of remote sensing and ancillary data for geographical analysis and risk assessment of forest regeneration failures

   Författare :Maj-Liz Nordberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The spatial distribution and size of forest regeneration areas are the basis for an analysis of where climatically unfavourable sites for forest regeneration are likely to occur if the area is clear felled. Knowledge about thermal variations is of interest in forestry, as avoidance of surface temperature extremes is important to regeneration success. LÄS MER

5. 19. Analyses of genetic diversity and desirable traits in sesame (Sesamum indicum L., Pedaliaceae) : implication for breeding and conservation

   Författare :Toan Duc Pham; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Sesame (Sesamum indicum L., Pedaliaceae) is a traditional oil crop cultivated in Vietnam and Cambodia. It is known as the king of oil seeds in Vietnam due to the high oil content (50-60%) in its seed. LÄS MER

7. 20. School choice, space and the geography of marketization- Analyses of educational restructuring in upper secondary education in Sweden

   Författare :Anna Maria Fjellman; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school choice; school market; marketization; space; equity; quasi-market; differentiation; spatial justice;

   Sammanfattning : The main aim of the dissertation is to investigate, analyze and create a research-based understanding of the spatialities of the Swedish school choice in upper secondary education using a socio-spatial framework. The dissertation is comprised of three empirical studies based on six cohorts of register data from The Gothenburg Longitudinal Database. LÄS MER
