1. 16. Reluctantly Virtual : Modelling Copyright Industry Dynamics

   Författare :Patrik Wikström; Robert Burnett; Will Straw; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Music industry dynamics; Internet; Media; Production of culture; Qualitative system dynamics modelling; Organisational adaptation; Copyright; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap; Business studies;

   Sammanfattning : During the evolution of the music industry, developments in the media environment have required music firms to adapt in order to survive. Changes in broadcast radio programming during the 1950s; the Compact Cassette during the 1970s; and the deregulation of media ownership during the 1990s are all examples of changes which have heavily affected the music industry.

3. 17. On multilayered system dynamics and waves in anisotropic poroelastic media

   Författare :Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Wennhage Wennhage; Camille Perrot; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poroelastic media; anisotropy; plane waves; multilayered systems; dynamics; acoustics; optimisation; matériaux poro-visco-élastique; anisotropie; ondes planes; panneaux multicouches; dynamique; acoustique; optimisation; Poroelastiska material; anisotropi; planvågor; flerskiktssystem; dynamik; akustik; optimering; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. LÄS MER

4. 18. On the dynamics of footbridges : A theoretical approach and a comparison between running and walking loads

   Författare :Daniel Colmenares; Raid Karoumi; Andreas Andersson; Mahir Ülker Kaustell; Pedro Museros Romero; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; footbridges; dynamics; human induced loads; human structure interaction; harmonic load; continuous beam; gångbroar; dynamik; fotgängarlast; samverkan mellan fotgängare och bro; harmonisk last; kontinuerlig balk.; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : The dynamic behaviour of lightweight footbridges is often susceptible to HumanInduced Loads (HILs). Generally HILs are taken into account as moving harmonicfunctions in which the loading frequency represents the step frequency of the pedestrians. LÄS MER

7. 20. The Global Fashion System : On its social-ecological intertwinedness

   Författare :Celinda Palm; Sarah E. Cornell; Tiina Häyhä; Fredrik Moberg; Kate Fletcher; Stockholms universitet; []
   Nyckelord :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;

   Sammanfattning : 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.
