  1. 1. Stewardship in an urban world : Civic engagement and human–nature relations in the Anthropocene

    Författare :Johan Enqvist; Maria Tengö; Örjan Bodin; Bengt G. Karlsson; Richard C. Stedman; Morgan Grove; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agency; Bengaluru; boundary object; care; civil society; community; environmental ethics; knowledge; natural resource management; New York City; problem of fit; rigidity trap; sense of place; social–ecological system; urbanization; water governance; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Never before have humans wielded a greater ability to alter and disrupt planetary processes. Our impact is becoming so noticeable that a new geological epoch has been proposed – the Anthropocene – in which Earth systems might no longer maintain the stable and predictable conditions of the past 12 millennia.

  3. 2. Urban environmental stewardship : Roles and reasons for civic engagements in governance of social-ecological systems

    Författare :Johan Enqvist; Maria Tengö; Örjan Bodin; Bengt Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental governance; urbanization; social-ecological systems; Bangalore; India; collective action; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Stewardship as a concept is increasingly brought forward as a goal to reach sustainability goals of ensuring human wellbeing within the limits of Earth’s life support systems. Scholarship on the required capacities for planetary stewardship is growing rapidly, as are the insights. LÄS MER

  4. 3. Graybox Modelling of Ships Using Indirect Input Measurements

    Författare :Jonas Linder; Martin Enqvist; Fredrik Gustafsson; Johan Sjöberg; Magnus Mossberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A ship's roll dynamics is very sensitive to changes in the loading conditions and a worst-case scenario is that the ship will capsize. Actually, the mass and center of mass are two of the most influential parameters in most mechanical systems. LÄS MER

    Sammanfattning : Linear matrix equations and nonlinear eigenvalue problems (NEP) appear in a wide variety of applications in science and engineering. Important special cases of the former are the Lyapunov equation, the Sylvester equation, and their respective generalizations. These appear, e.g. LÄS MER
