  2. 1. Studies in Local Public Transport Demand

    Author : Johan Holmgren; Jan Owen Jansson; Lars Westin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Demand; Elasticity; Price; Service; Time series; Panel data; Kollektivtrafik; Efterfrågan; Elasticitet; Pris; Trafikutbud; Inkomst; Bilinnehav; Tidsserieanalys; Paneldata; Economics; Nationalekonomi;

    Abstract : This thesis consists of four papers where the overall purpose is to contribute to the understanding of how local public transport demand is affected by different factors. An underlying theme running trough the thesis is the two-way relationship between public transport demand and the service level caused by the fact that capacity and quality are joint products.

  5. 3. Analyzing Vegetation Trends with Sensor Data from Earth Observation Satellites

    Author : Sadegh Jamali; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change detection; Satellite sensor data; Time series analysis; Vegetation dynamics; Vegetation index;

    Abstract : Abstract This thesis aims to advance the analysis of nonlinear trends in time series of vegetation data from Earth observation satellite sensors. This is accomplished by developing fast, efficient methods suitable for large volumes of data. READ MORE

  6. 4. The Development of Parliamentarism in Western Europe

    Author : Simon Davidsson; Statsvetenskapliga institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; parlamentarism; partisystem; västeuropa; institutionell förändring; parliamentarism; party systems; Western Europe; institutional change;

    Abstract : This dissertation describes and explains the development of parliamentarism in Western Europe. Defining parliamentarism as an institutional solution in which the government is politically responsible to parliament only, I use country historiography to map out a tug-of-war between parliament and the head of state over the ability to make governments resign or maintain them in office in 11 West European countries since the establishment of national parliaments.
