OBJECTIVES: This is the first nationwide study with the aim to analyze whether there is an association between country of birth in first-generation immigrants and hospitalization for type 2 diabetes (T2D), and to study whether any such association remains in second-generation immigrants. DESIGN: In this follow-up study, the Swedish Hospital Discharge Register was used to identify all hospital

In epidemiological and twin populations, prior interview studies have identified an externalizing spectrum of disorders. Could this be detected utilizing objective registry data? In 20,603 twin pairs from the Swedish Twin Registry, we obtained information from national medical, criminal and pharmacy records on drug abuse (DA), criminal behavior (CB) and alcohol use disorders (AUD). Multivariate tw

Risk and vulnerability analyses can play important roles in the society’s proactive emergency management. This thesis addresses two ways of improving the analysis of risk and vulnerability analysis in this context. First, by developing methods for risk and vulnerability analysis of technical infrastructure networks and emergency response systems. Secondly, by aiming to improve practises related to

In the developed countries the public expect society to be prepared for, and step in, if something out of the ordinary happens. This public pressure appears to have increased the demand for crisis preparedness planning. In crisis management the local authority serves as the first line of defence and will more or less always be involved in responding to crises. It is therefore important to study ho

Popular Abstract in Swedish Evolusjon og energikonservering i en katalysator i cellens kraftverk Alle levende organismer må omforme energien i mat eller sollys til en form som cellen kan bruke som energi. Energien brukes både til prosesser som bryter ned og bygger opp komponenter i cellen. Den brukes også til prosesser som muskelsammentrekninger, celledelinger og bevegelser. Uansett hva slags celComplex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. In mammals, about 50% of the mitochondrial DNA is encoding protei

This paper presents a case study of decision-making at the design stage of a socio-technical system where resilience at the global level of the system was constrained by the local perspectives adopted by the different stakeholders. The study is based on interviews with key decision-makers involved in the design stage of six railway tunnel projects in Sweden. The results show that differences in ro

This study considers detection of polyproline type II secondary structures from protein sequences. This difficult problem was handled with multilayer perceptron neural networks, which were found to be useful for such bioinformatics studies. Polyproline II secondary structures have not previously been tried to be predicted from sequences.

BACKGROUND: Spousal caregivers of cancer patients suffer psychological and physical burdens, which may affect their risk of subsequently developing coronary heart disease (CHD) and stroke. METHODS AND RESULTS: Cancer patients were identified in the Swedish Cancer Registry, and information on their spouses was retrieved from the Swedish Multi-Generation Register. Follow-up of caregivers was carri

This report presents the research concerned with vulnerability analysis of technical infrastructure networks conducted in the research framework programme called FRIVA. The report reviews how network analysis has been used to analyse the vulnerability of systems that are possible to model as networks, such as technical infrastructure systems. In addition, it proposes how these methods can be devel

The fundamental problems related to uncertainty in quantitative risk analyses, used in decision making in safety-related issues (for instance, in land use planning and licensing procedures for hazardous establishments and activities) are presented and discussed, together with the different types of uncertainty that are introduced in the various stages of an analysis. A survey of methods for the pr

The present thesis concerns methods and knowledge that are useful when analysing the risks and vulnerabilities of complex systems in a societal emergency management context. Operational definitions of vulnerability and emergency response capabilities are suggested and two methods for analysing the vulnerability of critical infrastructure networks, based on the suggested definition, are presented.

An operational definition of vulnerability is proposed. The definition is used to describe and analyse different methods for risk and vulnerability analysis. Several problems related to analysing the vulnerability of a complex sociotechnical system to a specific perturbation are identified and discussed. Suggestions of how risk- and vulnerability analyses can be performed for such systems are pres
