  2. 6. Dynamics in meetings : on leadership and followership in ordinary meetings in different organizations

    Author : Kjell Granström; Karin Aronsson-Ottosson; Per Linell; Linköpings universitet; []
    Keywords : group processes; leadership; followership; decision-making; the school as an organization; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : A method for analyzing interactional dynamics in regular meetings and sessions was developed on the basis of Bion's (1961) basic-assumption model. This model postulates that members in groups frequently take part in collective defence activities which prevent the group from carrying out the tasks assigned to them. READ MORE

  4. 7. Collective Excitation Dynamics in Molecular Aggregates

    Author : Mats Dahlbom; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Fysik; Physics; computational methods; photosynthesis; femtosecond spectroscopy; Exciton; Polaron;

    Abstract : The aim of this thesis is to study collective excitation dynamics in molecular aggregates. Half of the work presented here is method development and the remainder is application of these methods to several di.erent molecular aggregates. READ MORE

  5. 8. Protein-water interactions studied by molecular dynamics simulations

    Author : Filip Persson; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Abstract : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. READ MORE

  6. 9. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics

    Author : David Andersson; Astrid de WIjn; Supriya Krishnamurthy; Nicola Manini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tribology; nanofriction; 2d materials; graphene; image reconstruction; social dynamics; common-pool resource; collective action; simple models; teoretisk fysik; Theoretical Physics;

    Abstract : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. READ MORE

  7. 10. Modelling collective movement and transport network formation in living systems

    Author : Arianna Bottinelli; David Sumpter; Renaud Lambiotte; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal collective behaviour; transport networks; crowd dynamics; complex systems; ants; fish; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : The emergence of collective patterns from repeated local interactions between individuals is a common feature to most living systems, spanning a variety of scales from cells to animals and humans. Subjects of this thesis are two aspects of emergent complexity in living systems: collective movement and transport network formation. READ MORE
