    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dental students; Swedish dental education; work and organisational theories; gender power relations; ambiguity; perceived stress; satisfaction; grounded theory; content analysis; SEM; cluster analysis; tandläkarstudenter; svensk tandläkarutbildning; arbets- och organisations teorier; genus och makt relationer; ambiguitet; upplevd stress; nöjdhet; grundad teori; innehållsanalys; SEM; kluster analys; Applied psychology; Tillämpad psykologi; Psychology; psykologi;

    Sammanfattning : This thesis explores how dental students experience their education. We aim to generate ways to understand which elements relate to the students’ experience based on current theories and models regarding the quality of working life and gender (and) power relations. LÄS MER

  5. 4. Cost of searching : probabilistic analysis of the self-organizing move-to-front and move -to-root sorting rules

    Författare :Josefin Bodell; KTH; []
    Nyckelord :;

    Sammanfattning : Consider two (or more) users who request records in adatabase independently and with different frequencies. On arequest, the user's probability of calling a certain record iseither constant or changes deterministically in time. One userhas priority over the other(s) and rearranges the recordsaccording to seff-organizing rules. LÄS MER
