   Sammanfattning : The rapid advances in information and communication technology enable a shift from diverse systems empowered mainly by either hardware or software to cyber-physical systems (CPSs) that are driving Critical infrastructures (CIs), such as energy and manufacturing systems. However, alongside the expected enhancements in efficiency and reliability, the induced connectivity exposes these CIs to cyberattacks exemplified by Stuxnet and WannaCry ransomware cyber incidents.

3. 32. Public computer systems, the client-organization encounter, and the societal dialogue

   Författare :Åke Grönlund; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Public computer systems; societal information systems; participation; societal dialogue; communication; information systems; Internet;

   Sammanfattning : Public computer systems (PCS) are systems designed for use at the interface between organizations and their clients. PCS intervene in client-organization relations; the questions discussed in this thesis are what role they play in the client-organization encounter, what role they could and should play, and what theories might be available to guide the development of such systems.

4. 33. Beställarkompetens vid upphandling och utveckling av IT : Om kompetensframväxt i skuggan av kunskapsfragmentering

   Författare :Michel Thomsen; Sven Carlsson; Thomas Kalling; Karin Axelsson; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; knowledge; fragmentation; systems development; competence; systems acquisition; beställarkompetens; Informatics; Informatik; fragmentation; knowledge; systems development; competence; systems acquisition; beställarkompetens;

   Sammanfattning : Ever since IT started to become important and strategic assets in organizational practices, systems acquisitions have been a challenging and complex endeavor. There are seemingly never ending reports of unsuccessful IT acquisitions and lack of systems acquisition competence (beställarkompetens in Swedish). LÄS MER

5. 34. New Forms of Collaboration in Emergency Response Systems : A framework for participatory design of information systems

   Författare :Kayvan Yousefi Mojir; Sofie P Pilemalm; Stefan Holgersson; Björn JE Johansson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : An emergency response systems (ERS) is usually responsible for delivering essential services to save lives and minimise environmental damage in case of small, frequent or large-scale emergencies. The ongoing global financial crisis, lack of professional resources, public sector cuts and rising public expectations are some of the challenges ERSs currently are facing. LÄS MER
