  1. 1. Occupying Time Design, Time, and the Form of Interaction

    Författare :Ramia Mazé; Blekinge Tekniska Högskola.; Blekinge Institute of Technology.; [2007]
    Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY;

    Sammanfattning : As technology pervades our everyday life and material culture, new possibilities and problematics are raised for design. Attention in contemporary design discourse is shifting ‘beyond the object’, to the qualities of processes and experiences. LÄS MER

  3. 2. Commuting Time Choice and the Value of Travel Time

    Detta är en avhandling från Örebro : Örebro University

    Författare :Jan-Erik Swärdh; Örebro universitet.; [2009]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value of time; Value of travel time; Commuting; Commuting time changes; Value of commuting time; Register data; On-the-job search; Revealed preferences; Stated preferences; Hypothetical bias; Scheduling constraints; Relocations; Certainty calibration; Quantile regression; Mixed logit; Gender differences; nationalekonomi; Economics;

    Sammanfattning : In the modern industrialized society, a long commuting time is becoming more and more common. However, commuting results in a number of different costs, for example, external costs such as congestion and pollution as well as internal costs such as individual time consumption. LÄS MER

  4. 3. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

    Detta är en avhandling från Umeå : Statistik

    Författare :Danardono; Umeå universitet.; [2005]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; statistik;

    Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.
