1. 1. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

   Författare :Hördur Haraldsson; Avdelningen för kemiteknik; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Essays on structural equation modelling with applications of the basic univariate twin model

   Författare :Stefan Mattson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; statistik; Statistics;

   Sammanfattning : Structural equation models have proven useful for studies of genetic and environmental effects forvarious traits end the classical twin study has been considered as a powerful design for such studies. This thesis consist of five papers dealing with the analysis of structural equation models with applications of the basic univariate twin model. LÄS MER

4. 3. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities

   Författare :Angelica Chirico; Johan Eklöf; Nils Kautsky; Even Moland; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; conservation; marine spatial planning; locally managed; fisheries closure; benthic communities; fish; foundation species; macroalgae; secondary succession; life-history; trait variability; plasticity; tourism; human disturbance; fishing; experimental research; Western Indian Ocean; causal modelling; structural equation model; permanova; multivariate data; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Tropical seagrass beds and coral reefs are among the most productive and diverse ecosystems on Earth and provide ecosystem services, such as fish production and coastal protection, and support livelihoods of millions of people. At the same time, these ecosystems are threatened globally by anthropogenic disturbances, such as overfishing, pollution and global warming. LÄS MER

5. 4. A Value Co-Creation Perspective on Customer-Based Brand Equity Modelling for Tourism Destinations : A case from Sweden

   Författare :Tatiana Chekalina; Matthias Fuchs; Maria Lexhagen; William C. Gartner; Mittuniversitetet; []
   Nyckelord :Destination branding; customer-based brand equity; value co-creation; value-in-use; Åre; linear structural equation modelling;

   Sammanfattning : Tourism destinations all over the world increasingly embrace marketing and branding practices traditionally utilized by businesses. However, the literature on customer-based brand equity modelling and measurement for tourism destinations lacks the conceptual understanding of the complex relationships between tourists and the destination brand.

7. 5. Kamrateffekter i skolundervisning – En ramfaktorteoretisk analys

   Författare :Pontus Bäckström; Sangeeta Bagga-Gupta; Rebecka Florin Sädbom; Vezir Aktaş; Ulf P. Lundgren; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; compositional effects; peer effects; frame factor theory; structural equation modelling;

   Sammanfattning : In the educational literature on peer effects, attention has been brought to the fact that the mechanisms creating peer effects are still to a large extent hidden in obscurity. The hypothesis in this study is that the Frame Factor Theory can be used to explain these mechanisms. LÄS MER
