Technical infrastructures of the society are becoming more and more interconnected and interdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Disturbances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important
We derive process limit distribution results for the Nelson–Aalen estimator of a hazard function and for the Kaplan–Meier estimator of a distribution function, under different dependence assumptions. The data are assumed to be right censored observations of a stationary time series. We treat weakly dependent as well as long range dependent data, and allow for qualitative differences in the depende
De riskreducerande åtgärder som ska införas när byggnader placeras nära farliga riskkällor verkar ibland kunna förändras eller till och med försvinna innan byggprojektet är färdigt. Detta kan bero på svårigheter med kommunikation, men det finns även andra orsaker. I ett samhälle kan det finnas industrier som sysslar med giftiga kemikalier eller godståg som fraktar farliga ämnen. Detta kan medfBuildings are sometimes raised in the vicinity of risk objects such as hazardous industries and routes used for transportation of hazardous goods. To compensate for the increased risk level risk reducing measures can be implemented. However, the planning and construction process is long and complex, and for these measures to be implemented they must somehow be conveyed through this process. The pu
Snö, glaciärer och regn över bergsområden möjliggör dricksvatten för miljoner av människor och fungerar som vattenreservoar för hela ekosystem. Under rådande klimatförändringar har smältande glaciärer i Himalaya blivit ett känt hot mot framtida dricksvattenförsörjning, men glaciärerna är inte de enda processer som påverkar tillgången på vatten. För att ta beslut som säkrar framtida vattentillgänglIn the central Himalayas, water dynamics are expected to change due to multiple factors like climate change, hydro power development and shifting land use practices. This thesis looks at possible changes in water dynamics in Marsyandi river basin, Nepal, as well as causes to those changes and how they are perceived locally. Grounded in critical physical geography, the study uses mixed methods an
Yoga can reduce blood pressure and has also been suggested to reduce inflammatory biomarkers and metabolic risk factors for cardiovascular diseases (CVDs). We aimed to assess the benefit of two yoga interventions on inflammatory biomarkers and metabolic risk factors in a high risk population in primary care.
This paper deals with the implementation of model selection criteria to data generated by ARMA processes. The recently introduced modified divergence information criterion is used and compared with traditional selection criteria like the Akaike information criterion (AIC) and the Schwarz information criterion (SIC). The appropriateness of the selected model is tested for one- and five-step ahead p
The main interest of designers is not only to determine the amplitudes of tillage forces but also the type of their distributions under different soil mechanical properties with object of achieving reliable designs. Whereas, the deterministic design approach consists in achieving designs without considering the randomness of the design parameters that may lead to non reliable designs. In this work
Alcohol consumption contributes to many negative health consequences and is a risk factor for death. Some previous studies however suggest a J-shaped relationship between the level of alcohol consumption and all-cause mortality. These findings have in part been suggested to be due to confounders. The aim of our study was to analyze the relationship between self-reported alcohol intake and all-caus
Crisis management exercises sometimes produce weak or vague learning results with very limited applicability. This paper addresses these problems by developing a theoretical framework on learning from crisis management exercises. The framework focuses on necessary requirements and beneficial factors for the conceptual learning of individuals from discussion-based exercises. The variation theory of
Popular Abstract in Swedish Bröstcancer är den vanligaste cancerdiagnosen hos kvinnor, och under år 2011 fick över 8000 svenska kvinnor denna diagnos. Termen bröstcancer är egentligen ett samlingsnamn för alla de olika typer av cancer som kan uppstå i bröstet. En del typer av bröstcancer har en bra prognos medan andra trots aggressiv behandling alltjämt har en dålig prognos. Cancer är en sjukdom dBreast cancer is a heterogenous disease which can be divided in subgroups of distinct biology with disparate prognosis and response to treatment. The overall aim of this thesis was to delineate subgroup specific behaviour in breast cancer cells with focus on proliferation, migration and stem-like cell activity. In addition, we have studied the functional retinoblastoma tumour suppressor (RB) prote
Background: Many older adults are physically inactive and inactivity increases with age. This knowledge comes from cross-sectional studies. Cross-sectional studies may miss important trajectories within the older adults as a result of retirements, and poor health impact of promotional efforts. The aim of this study was to analyse, longitudinally, the annual effects of age group and birth cohort on
Background: The aim of this study is to analyze longitudinally, based on four measurements at intervals of eight years, the annual effect of age group and birth cohort on regular exercise in the Swedish population from 1980-1981 to 2004-2005. Methods: We followed a randomly drawn subsample of individuals aged 16-63 years, interviewed by professional interviewers, from the Swedish Annual Level of L
Background: The aim of this longitudinal study was to analyze whether mean Body Mass Index (BMI), assessed at four occasions, changed within different age groups and birth cohorts over time, i.e., between 1980/81 and 2004/05, after adjustment for possible confounders. Methods: A sample of 2728 men and 2770 women aged 16-71 years at study start were randomly drawn from the Swedish Total Population
Background: Leptin resistance is considered a primary risk factor for obesity. It has been hypothesized that dietary cereal grain protein could cause leptin resistance by preventing leptin from binding to its receptor. Non-degraded dietary wheat protein has been found in human serum at a mean level of 41 ng/mL. Here, we report our findings from testing whether enzymatically digested gluten from wh
P>Aims Type 1 diabetes mellitus (T1DM) is an autoimmune disease with potential mechanistic links to immune-related cancers. We aimed at examining the overall and specific cancer risks among hospitalized T1DM patients from the national registers in Sweden. Methods A T1DM research cohort was created by identifying T1DM patients from the Hospital Discharge Register and linking them with the Cancer Re

This study analyses the importance of timing reconciliation in a conflict/peace process in order to reach a sustainable peace. There is a main divide in how the different scholars in the conflict resolution field define reconciliation in being a goal or a process, or both. Mostly reconciliation initiatives are worked with during the post-settlement period but in the protracted conflicts of today t
Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in
Background: More knowledge is needed on potential associations between individual-, family-, and neighborhood-level factors and psychiatric disorders in children and adolescents. Aims: To examine associations between, individual-, family-, and neighborhood-level factors and incident internalizing (anxiety and mood) disorders and externalizing (ADHD and conduct) disorders in children and adolesc
