16. Development and application of competing risks and multi-state models in cancer epidemiology
Sammanfattning : Competing risks and multi-state models allow us to study complex disease settings and answer composite research questions and should be used more widely in epidemiology. This thesis aims to explore the competing risks and multi-state models areas using flexible parametric survival models (FPSMs), studying several aspects, such as the choice of timescale, choice of multi-state structure, sharing information across transitions by imposing restrictions in the estimation of the parameters, as well as communicating the results of such models to a wider audience and evaluating the use of recurrent multi-state structures in the area of recurrent events when a terminal event is present.

17. Application of the benchmark dose-response modelling approach for risk characterization of chemicals
Sammanfattning : Toxicology is the discipline that investigates the possible adverse effects of chemical exposure on human, animal and environmental health. Chemical risk assessment is the process that aims to identify potentially hazardous substances and describes the probability of adverse outcomes associated with their exposure. LÄS MER
18. A normative application of multi-modal systems thinking to a non-viable social system
Sammanfattning : This research evaluates how multi-modal systems thinking, a normative approach to systems science, answers to the theoretical, practical and ethical demands emerging from research in sustainability and to systems scientists concerned with the norms of life and ethics. The thesis starts with a broad survey of sustainability literature and concludes that this multi-modal systems methodology, which has emerged during the last decade, has a significant contribution to make.

19. Development and characterization of damped cubic response functions with application to two-photon absorption
Sammanfattning : Molecular response to electromagnetic fields - static or optical - within a framework of perturbation theory diverges close to resonance with molecular transitionen energies, and need work-around solutions for real-valued response functions. This licentiate thesis deals with nonlinear response, with focus being on cubic polarizaibilities, and outlines the underlying mathematics for exact-state and approximatestate, complex-valued response functions applicable to quantum chemical computation.

20. Laser Absorption Spectroscopy of Gas in Scattering Media
Sammanfattning : Absorption spectroscopy constitutes a chemical analysis tool which can be applied to various samples and application fields. This thesis focuses on gas absorption spectroscopy with the means of diode lasers - tunable diode laser absorption spectroscopy, TDLAS. LÄS MER
