  1. 6. Mating system evolution and self-incompatibility in the wild plant species Brassica cretica

    Författare :Kristina Aaltonen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mating system; Brassicaceae; Brassica cretica; recombination; frequency-dependent selection; evolution; population structure; segregation distortion; SCR; self-incompatibility; SRK;

    Sammanfattning : Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). LÄS MER

  3. 7. Insights from combining Action Research and System Dynamics when facilitating change and improvement processes in healthcare

    Författare :Paul Holmström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; healthcare; improvement; change; implementation; action research; system dynamics; simulation;

    Sammanfattning : BACKGROUND Healthcare is a complex system with multi-professional staff and multiple patient care pathways. Time pressure and minimal margins for error makes it challenging to implement new policies or procedures, no matter how desirable. Changes in healthcare also requires the participation of the multi-professional staff. LÄS MER

  4. 8. Unravelling Sustainability : The complex dynamics of emergent environmental governance and management systems at multiple scales

    Författare :Lucas Dawson; Ingrid Stjernquist; Marine Elbakidze; Raimonds Ernsteins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Integrated adaptive environmental governance and management; Social-ecological system dynamics; Complex systems; Sustainability transitions; Sustainability strategies; Multi-level governance; Causal loop diagrams; Green Infrastructure; Landscape restoration; Habitat restoration; Biodiversity conservation; Comprehensive planning; Stakeholder participation; System thinking; Water Framework Directive; Sustainable water governance; Collaborative learning; Communities of practice; Knowledge management; Physical Geography; naturgeografi;

    Sammanfattning : This thesis adopts a complex systems approach to investigate the dynamic emergence of sustainable environmental governance and management systems in multiple contexts in Europe. Accelerating rates of environmental degradation across the world have called the legitimacy of previous environmental governance and management arrangements into question. LÄS MER

  5. 9. Involvement of the Opioid System in High Alcohol Consumption : Environmental and Genetic Influences

    Författare :Karolina Ploj; Jörgen A Engel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Opioids; ethanol; stress; maternal separation; neonatal handling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : It is well accepted that both inherent and environmental factors influence the pathogenesis of alcohol dependence. This thesis investigates the role of the opioid system in the initiation and maintenance of high ethanol intake. LÄS MER

  7. 10. Complex methods of inquiry: structuring uncertainty

    Författare :PETER BEDNAR; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system; Contextual Analysis; Contextual Dependencies; Systems Approaches; Systems Thinking; Organizational change; Complex adaptive systems; Uncertainty management; Organizational Emergence; Change Management; Organizational Learning; Human Activity Systems;

    Sammanfattning : Organizational problem spaces can be viewed as complex, uncertain and ambiguous. They can also be understood as open problem spaces. As such, any engagement with them, and any effort to intervene in order to pursue desirable change, cannot be assumed to be just a matter of ‘complicatedness’. LÄS MER
