  3. 17. Subject retrieval in web-based library catalogs

    Författare :Koraljka Golub; Jadranka Lasić-Lazić; Department of Information Science Filozofski fakultet u Zagrebu; []

    Sammanfattning : This thesis has been motivated by past research, problems and realizations that online library catalog users frequently perform subject searches – using keywords, subject headings and descriptors – and these searches have yielded unsatisfactory results. Web-based catalogs or WebPACs (Web-based Online Public Access Catalogs), belonging to the so-called third generation of online catalogs and providing a wide variety of search options, remain largely underutilized despite the continuous advancement of information retrieval systems.

  4. 18. Assessment of physical activity and energy expenditure in adolescents

    Författare :Ulf Ekelund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Accelerometry; Activity diary; Doubly labelled water; Heart rate monitoring; FLEX HR; Oxygen uptake; Physical activity level; Total energy expenditure; ;

    Sammanfattning : Physical activity (PA) is a complex, multidimensional human behaviour that includes all bodily movement from fidgeting to participation in marathon running. The detailed relationship (i.e. dose - response) between the type and degree of PA and its effects on various aspects of health remains to be elucidated, not least in young people. LÄS MER

  7. 20. Gösta Werner och filmen som konst och propaganda

    Författare :Emil Stjernholm; Filmvetenskap; []
    Nyckelord :propaganda; beställningsfilm; journalfilm; experimentfilm;

    Sammanfattning : Gösta Werner (1908–2009) var en svensk filmpionjär som i rollen som redaktör, regissör och forskare gjorde starkt avtryck på den offentliga debatten om filmen som konstform. Genom att studera denna framträdande filmpersonlighets texter och filmer belyser avhandlingen ett antal viktiga kulturpolitiska strider inom den framväxande svenska konstfilmsinstitutionen, däribland om filmstudiets formering, filmens status som konstform och mediets verkan som propaganda.
