1. 1. Hänsynstagandets paradoxer : Om äldre, närstående och biståndshandläggare vid flytt till särskilt boende

   Författare :Maria Söderberg; Socialhögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; consideration; independence; self-determination; residential home; relocation; care manager; family member; older people; hänsyn; självbestämmande; särskilt boende; självständighet; flyttning; biståndshandläggare; närstående; äldre person;

   Sammanfattning : Many older people express strong preferences to remain in their own housing as long as possible. Due to declining health they may, however, become dependent on others for their daily care, eventually reaching a point where they consider relocation to a residential home. LÄS MER

3. 2. Migration strategies of raptors – spatio-temporal adaptations and constraints in travelling and foraging

   Författare :Roine Strandberg; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; route convergence; loop migration; mortality; spatio-temporal distribution patterns; pre- and post-migratory movements; daily travel routines; satellite tracking; fly-and-forage migration; raptors;

   Sammanfattning : My dissertation is about bird migration and addresses questions about how raptors adapt to the fluctuating environments during the transition seasons between breeding and wintering. The migration is highly affected by local prey abundance, foraging strategies, weather conditions and landscape patterns along the migration routes as well as navigation and orientation mechanisms and cues.

4. 3. Genetic Variation and Migration of Waders

   Författare :Liv Wennerberg; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mtDNA sequencing; microsatellite analysis; Dunlin; Calidris alpina; Curlew Sandpiper; Calidris ferruginea; White-rumped Sandpiper; Calidris fuscicollis; carbon isotope ratios; Zoologi; Zoology; Ecology; bird migration; population genetics; Ekologi; Animal ecology; Djurekologi;

   Sammanfattning : The migratory behaviour of birds has received much scientific interest, though many questions still remain unsolved. One of the reasons for this is the difficulty of following the birds as they move between breeding and wintering localities. Populations may mix on migration and the origin of individual birds is difficult to assess. LÄS MER

5. 4. Leaving Home in a Peasant Society. Economic Fluctuations, Household Dynamics and Youth Migration in Southern Sweden, 1829-1866

   Författare :Martin Dribe; Ekonomisk-historiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; historical demography; economic stress; migration; family strategy; longitudinal analysis; leaving home; event-history analysis; Ekonomisk och social historia;

   Sammanfattning : This study deals with the process of children leaving home and its interactions with the household economy in preindustrial society. A theoretical model of leaving home is outlined and then analyzed multivariately, using a longitudinal micro-level dataset for a sample of parishes in western Scania, Sweden, for the period 1829-1866.

7. 5. Flight Behaviour of Passerines on Nocturnal Migration

   Författare :Cecilia Nilsson; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bird migration; Passerines; Flight Behaviour; Tracking radar; Optimal migration; Flight speed; Airspeed; Wind drift; Nocturnal migration; Coastline effects; Flight directions; Reverse migration;

   Sammanfattning : Many passerines migrate during the night and at high altitudes, making their migration difficult to observe. By using tracking radars we have been able to make exact observations of the flight behaviour of passerines on nocturnal migration, which has enabled us to test several hypotheses about adaptive values and constraints regarding migratory behaviour in different ecological contexts.
