    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Monetary Exchange Rate Model; Homogeneity Testing; Panel Cointegration; Pooling; Duration of Trade; Unemployment Duration; Proportional Hazards; Unobserved Heterogeneity; Hazard Rate; Discrete-Time Duration Model; Threshold Excess Model;

    Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. LÄS MER

  3. 2. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

    Författare :Andreas Lindhe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

    Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER

  4. 3. Essays on Shocks, Welfare, and Poverty Dynamics: Microeconometric Evidence from Ethiopia

    Författare :Yonas Alem; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban Ethiopia; poverty dynamics; dynamic probit; hazard rate; labor market status; subjective well-being; policymakers; life satisfaction; environment; Ethiopia; food price; consumer demand; fertilizer use; rainfall; highlands of Ethiopia; panel data; consumption; welfare; food price shock; Africa;

    Sammanfattning : Five self-contained papers constitute this thesis. Paper 1: Does fertilizer use respond to rainfall variability? Panel data evidence from urban Ethiopia In this article, we use farmers’ actual experiences with changes in rainfall levels and their responses to these changes to assess whether patterns of fertilizer use are responsive to changes in rainfall patterns.

  5. 4. Risk factors for incident heart failure and atrial fibrillation in an elderly population : The role of cardiac conduction and heart rate variability

    Författare :Bozena Ostrowska; Carina Blomström Lundqvist; Lars Lind; Mikael Dellborg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; incident heart failure; incident atrial fibrillation; prediction of heart failure; short P-wave duration; heart rate variability.; Cardiology; Kardiologi;

    Sammanfattning : Heart failure (HF) and atrial fibrillation (AF) are epidemic diseases, frequently coexisting, sharing risk factors and conferring poor prognosis. Identification of individuals at high risk of HF and AF may enable early treatment and improve the prognosis. Reliable prediction models for daily clinical practice are lacking. LÄS MER

  7. 5. Towards reliable seismic hazard assessment in underground mines

    Författare :Wille Törnman; Savka Dineva; Jesper Martinsson; Adam Jonsson; Björn Lund; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to  design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.
