1. 1. Open the door to complexity : Safety climate and work processes in the operating room

   Författare :Camilla Göras; Anna Ehrenberg; Ulrica Nilsson; Maria Unbeck; Mirjam Ekstedt; Anna Forsberg; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient safety; operating room; complexity; safety climate; psychometrics; cross-sectional; observations and qualitative;

   Sammanfattning : A complex adaptive system such as the operating room (OR), consists of different safety cultures, sub-cultures and ways of working. When measuring, a strong safety climate has been associated with lower rates of surgical complications. Teamwork is an important factor of safety climate. LÄS MER

3. 2. To be or not to be: On system dynamics and the viability of mini-grids in rural electrification

   Författare :Elias Hartvigsson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system dynamics; rural electrification; reliability; mini-grids; complexity; load assessment;

   Sammanfattning : One to two billion people are expected to receive electricity access in developing countries in the coming decades. Many of these people will live in rural areas in developing countries where the existing grid will not be able to reach. These people will therefore rely on off-grid technologies to gain electricity access. LÄS MER

4. 3. Multi-level Interactions between Fisheries and Trade : Modeling intertwined social-ecological systems

   Författare :Laura G. Elsler; Schlüter Maja; Florian Diekert; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-level interactions; social-ecological model; trade relationships; complexity; inequality in fisheries; fisheries sustainability; seafood trade; international markets; fisheries collapse; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Sustainable and equitable fisheries are central for addressing the challenges of the UN Sustainable Development Goal 14: Life Below Water. International trade, once presented by Walrasian economists as a panacea for fisheries development, has not markedly decreased poverty and has been related to the overexploitation of marine species.

5. 4. Otrygghetens landskap. En kartläggning av otryggheten i stadsrummet och en analys av bakomliggande orsaker, med fokus på mediernas roll

   Författare :Gabriella Sandstig; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; risk society; late modernity; risk perception; mass communication; urban public space; sensations of fear and insecurity; threats; violence; fear of crime; social disorder; personal experience; social experience; media experience; personal predisposition; anxiety; social control; complexity; sex; gender; age; generalised trust; social capital; West Sweden; SOM-data; regression analysis; third-person-effect; third-person-effect-hypothesis; culivation effects; agenda setting;

   Sammanfattning : The aims of the dissertation are to explore and map the fear and insecurity in urban public spaces and to analyse the underlying causes behind the sensations of fear and insecurity in these spaces, with focus on the role of the media. The study is mainly based on survey data collected through regional samples of the population of West Sweden between the years of 2001–2007. LÄS MER

7. 5. On the optimization of opportunistic maintenance activities

   Författare :Adam Wojciechowski; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed integer linear programming; stochastic programming; complexity theory; mixed integer linear programming; complexity theory; stochastic programming;

   Sammanfattning : Maintenance is a source of large costs; in the EU the maintenance costs amountto between 4% and 8% of the total sales turnover. Opportunistic maintenance is anattempt to lower the maintenance cost by considering the failure of onecomponent as an opportunity to replace yet non-failed components in order toprevent future failures.
