   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subjective well-being; Depression; Life circumstances; Follow-up; Population-based; Caring sciences; Vårdvetenskap; Subjective well-being; depression; life circumstances; follow-up; population-based;

   Sammanfattning : This doctoral thesis examines various factors associated with subjective well-being (SWB) in an adult Swedish population, aged 20-64 years, using cross-sectional and longitudinal data. The thesis includes four studies based on the PART study, a current population-based study on mental health, work, and relations in Stockholm County, Sweden. LÄS MER

3. 2. Changing population distribution in Sweden : long term trends and contemporary tendencies

   Författare :Johan Håkansson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition;

   Sammanfattning : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). LÄS MER

4. 3. Population size, viability and genetic diversity in the orchid Gymnadenia conopsea

   Författare :Linus Söderquist; Nina Sletvold; Sophie Karrenberg; Hans Jacquemyn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; demography; extinction probability; genetic diversity; genetic rescue; genetic structure; Gymnadenia conopsea; orchid conservation; population viability; population size; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

   Sammanfattning : In this thesis, I combined controlled crosses with genetic and demographic data to examine how a main conservation value indicator, population size, was associated with estimates of population viability. I focused on the still common, but decreasing, perennial orchid Gymnadenia conopsea at two spatial scales—locally on the island Öland, in SE Sweden, and regionally across Scandinavia. LÄS MER

5. 4. Land use dynamics in the face of population increase. A study in the districts of Gatsibo and Nyagatare, Eastern Province, Rwanda

   Författare :Theophile NIYONZIMA; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; land use dynamics; land cover changes; population increase; cropping; livestock; political ecology; Rwanda;

   Sammanfattning : This thesis is about land use dynamics in areas undergoing population increase. The study was undertaken to clarify how the increasing population interacted with their physical environment through farming in Eastern Province, Rwanda. LÄS MER

7. 5. Risk factors for atrial fibrillation in population-based studies : Epidemiological perspectives

   Författare :Linda Johnson; Internmedicin - epidemiologi; []
   Nyckelord :Atrial fibrillation; Fasting plasma insulin; forced expiratory volume; glucose; hypertension; lung volumes; population; premature atrial contractions; risk factors; spirometry; supraventricular extrasystoles; supraventricular tachycardias systolic blood pressure; weight;

   Sammanfattning : Atrial fibrillation (AF) is common among the elderly, and has serious consequences such as stroke and increased mortality. Not all of the population attributable risk for AF is explained by known risk factors. LÄS MER
