    Sammanfattning : Optimal control theory has a long history and broad applications. Motivated by the goal of obtaining insights through unification and taking advantage of the abundant capability to generate data and perform online simulation, this thesis studies the discrete-time infinite horizon optimal control problems and introduces some approximate solution methods via abstract dynamic programming (DP) models.

  5. 19. Non-conveyed patients : a thesis on epidemiology, and patients' and ambulance clinicians' experiences

    Författare :Jakob Lederman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : BACKGROUND: As a consequence of the increased overall number of ambulance assignments in combination with an increase in patients assessed as having non-urgent complaints, new demands are being placed on the ambulance service and the ambulance clinicians (ACs) regarding patient assessments and decisions. Alternative care pathways – excluding emergency departments (EDs) – such as non-conveyance, have increased over the last decade. LÄS MER

  7. 20. Laws, Attitudes and Public Policy

    Sammanfattning : Paper 1: Do laws affect attitudes? An assessment of the Norwegian prostitution law using longitudinal data The question of whether laws affect attitudes has inspired scholars across many disciplines, but empirical knowledge is sparse. Using longitudinal survey data from Norway and Sweden, collected before and after the implementation of a Norwegian law criminalizing the purchase of sexual services, we assess the short-run effects on attitudes using a difference-indifferences approach.
