  2. 1. Planetary Timemaking : Paleoclimatology and the Temporalities of Environmental Knowledge, 1945-1990

    Author : Erik Isberg; Sverker Sörlin; Sabine Höhler; Adam Wickberg; Etienne Benson; KTH; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; paleoclimatology; environmental history; temporality; ice core; deep-sea core; North Atlantic; timemaking; theory of history; planetary-scale environmental knowledge; paleoklimatologi; miljöhistoria; temporalitet; iskärna; borrkärna; Nordatlanten; tidsskapande; historieteori; planetär miljökunskap; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

    Abstract : This thesis concerns the history of paleoclimatology in the postwar period. It follows the trajectory of two climate proxy records – ice cores and deep-sea cores – in the North Atlantic region, from their emergence as scientific objects in the 1940s to their incorporation into Earth System Science in the 1980s.

  4. 2. The Global Fashion System : On its social-ecological intertwinedness

    Author : Celinda Palm; Sarah E. Cornell; Tiina Häyhä; Fredrik Moberg; Kate Fletcher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainability; Fashion; Social-ecological system; Transdisciplinarity; Critical realism; Positionality; Hållbarhet; Mode; Social-ekologiska system; Tvärvetenskap; Kritisk realism; Positionalitet; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : The fashion industry contributes to shaping the state of the planet: impacts of production and consumption of textile fast-fashion are rising, and the growing number of sustainability-oriented actions have not slowed current trends. The industry’s (un)sustainability is mainly researched within two epistemic communities: fashion studies concerned with social sustainability, and circular economy focused on material biophysical and technological aspects of material cycles along the value chain.

  5. 3. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

    Author : Hördur Haraldsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

    Abstract : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. READ MORE

  6. 4. Turbulence-Assisted Planetary Growth : Hydrodynamical Simulations of Accretion Disks and Planet Formation

    Author : Wladimir Lyra; Nikolai Piskunov; Thomas Henning; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accretion; accretion disks; hydrodynamics; instabilities; methods: numerical; solar system: formation; planets and satellites: formation; magnetohydrodynamics MHD ; turbulence; diffusion; stars: planetary systems: formation; Astronomy and astrophysics; Astronomi och astrofysik;

    Abstract : The current paradigm in planet formation theory is developed around a hierarquical growth of solid bodies, from interstellar dust grains to rocky planetary cores. A particularly difficult phase in the process is the growth from meter-size boulders to planetary embryos of the size of our Moon or Mars. READ MORE

  7. 5. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications

    Author : Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Planetary boundaries; climate change; land-use change; Earth system interactions; ecosystem modeling; green water; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. READ MORE
