   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Djurekologi; Animal ecology; Ekologi; Ecology; weather; personality; partial migration; metabolic rate; evolution of migration; dominance; Cyanistes caeruleus; climate change; blue tit; behavioural strategies; bird migration;

   Sammanfattning : In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. LÄS MER

4. 3. Conifer Evolution, from Demography and Local Adaptation to Evolutionary Rates : Examples from the Picea genus

   Författare :Jun Chen; Martin Lascoux; Ulf Lagercrantz; Matt Olson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Speciation; Demographics; clinal variation; convergent evolution; transcriptome; small regulatory RNA; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Evolutionary process can be inferred at three different levels: the species level, the population level and the molecular level. In this thesis, I applied approaches at these three levels and aimed to get a comprehensive picture of conifer evolution, from speciation and demography to geographic variation and local adaptation, and then to the molecular evolution of proteins and small regulatory RNAs.

   Nyckelord :Bangladesh; disadvantaged populations; health-seeking behaviour; health-system; self-care;

   Sammanfattning : Background: Improving ability of the health system to reach the poor/disadvantaged populations is important for health and essential to mitigate the income-erosion consequences of ill- health in Bangladesh. This study examined the health-seeking behaviour of some identified disadvantaged population groups, including the effect of poverty focused non-governmental development interventions. LÄS MER

7. 5. Healthcare Priority Setting and Rare Diseases : What Matters When Reimbursing Orphan Drugs

   Författare :Johanna Wiss; Gustav Tinghög; Per Carlsson; Lars-Åke Levin; Ann-Charlotte Nedlund; Joanna Coast; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The rarity of a disease can give rise to challenges that differ from conventional diseases. For example, rarity hampers research and development of new drugs, and patients with severe, rare diseases have limited access to qualified treatments. When drugs are available, clinical evidence has higher uncertainty and the drugs can be very expensive. LÄS MER
