1. Meta-Languages and Semantics for Equation-Based Modeling and Simulation
Sammanfattning : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. LÄS MER
2. On the relation between psychosocial work environment and musculoskeletal symptoms : a structural equation modeling approach
Sammanfattning : The aim of the present thesis was to investigate the relation between aspects of the psychosocial work environment and musculoskeletal symptoms including the testing of process models of the potential mediating mechanisms of felt stress and perceived fatigue, and the potential moderating mechanism of physical workload. This thesis is based on four empirical studies. LÄS MER
3. Safety, Security, and Semantic Aspects of Equation-Based Object-Oriented Languages and Environments
Sammanfattning : During the last two decades, the interest for computer aided modeling and simulation of complex physical systems has witnessed a significant growth. The recent possibility to create acausal models, using components from different domains (e.g., electrical, mechanical, and hydraulic) enables new opportunities. LÄS MER
4. Effective schools in a segregated landscape : Studies of academic achievement and psychological well-being among adolescents in Sweden
Sammanfattning : Equitable educational opportunities necessitate equitable access to a favourable academic and social school environment. This thesis aims to explore the role of the school as an educational and social arena for the academic achievement and psychological well-being of lower secondary school students in Sweden. LÄS MER
5. Job characteristics, motivation and stress among information technology (IT) consultants
Sammanfattning : The general aim of the present thesis was to examine the relationship between job characteristics and perceived stress with motivators as the mediating variable in the information technology (IT) sector. This thesis is based on two empirical studies. LÄS MER
