   Sammanfattning : The world we live in is becoming digitalized by transforming our society and economyin an unpredicted way. Digital technologies are transforming products, manufacturingassets, and entire supply chains. LÄS MER

3. 2. The impact of increased standard flexibility on disclosure practices : a comparison of the introduction of IFRS 8 in the UK, Germany, France and Italy and its impact on companies' segment disclosures

   Författare :Giulia Giunti; Stefan Sundgren; Tobias Svanström; Walter Schuster; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; IFRS; IFRS 8; segment reporting; principles-based standards; standard flexibility; disclosure practices; harmonization; cross-country comparison; företagsekonomi; Business Studies;

   Sammanfattning : Following a series of reporting scandals in the early 2000s, several researchers studied the gradual shift toward more principles-based accounting systems. There seems to be a general belief that the adoption of international principles-based accounting standards will improve financial reporting quality worldwide, although little evidence is provided for this claim.

4. 3. Contributions to the Metamathematics of Arithmetic: Fixed Points, Independence, and Flexibility

   Författare :Rasmus Blanck; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; arithmetic; incompleteness; flexibility; independence; non-standard models; partial conservativity; interpretability;

   Sammanfattning : This thesis concerns the incompleteness phenomenon of first-order arithmetic: no consistent, r.e. theory T can prove every true arithmetical sentence. The first incompleteness result is due to Gödel; classic generalisations are due to Rosser, Feferman, Mostowski, and Kripke. LÄS MER

5. 4. Optimal Energy and Flexibility Dispatch of Grid-Connected Microgrids

   Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; microgrids; Battery energy storage; optimization.; energy scheduling; energy management; distribution network;

   Sammanfattning : This thesis proposes an optimization model to efficiently schedule energy and flexibilities of a grid-connected microgrid (MG) with non-dispatchable renewable energy sources and battery energy storages (BESs). The model can also be used to coordinate the MG operation with the connected upstream distribution grid and to assess the MG flexibility considering economic viability, technical feasibility, and BES degradation.

7. 5. Changes in Workplaces and Careers

   Författare :Christina Håkanson; Per Krusell; Claudia Olivetti; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technical change; skill sorting; cognitive skills; non-cognitive skills; employer-employee matched data; organizational change; female labor supply; fertility; flexibility; family-career trade-off; Economics; nationalekonomi;

   Sammanfattning : Organizational Change and Productivity Growth − Evidence from SwedenThis paper uses two different firm level surveys matched with employer-employee data to investigate both determinants and effects of different types of organizational change. The results support the competition hypothesis for inducing organizational change. LÄS MER
