    Nyckelord :HUMANIORA; HUMANITIES; national identity; societal security; language policy; ethnolinguistic conflict; human rights; language rights; ethnicity; multilingualism; immigration; critical discourse analysis; language attitudes; English language; Spanish language; United States;

    Sammanfattning : The narrative of the United States is of a "nation of immigrants" in which the language shift patterns of earlier ethnolinguistic groups have tended towards linguistic assimilation through English. In recent years, however, changes in the demographic landscape and language maintenance by non-English speaking immigrants, particularly Hispanics, have been perceived as threats and have led to calls for an official English language policy.

  3. 12. Om organiserad komplexitet : integration av organisering, lärande och kunnande

    Författare :Sören Augustinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : The overall purpose of the thesis is how organisations can be understood according their own conditions instead of trying to make them more rational and structured than they actually are in practice. In order to accomplish this, the thesis includes theoretical discussions with support in the following central concepts: organisation, learning and knowing. LÄS MER

  4. 13. Microwave sensors for scanning of sawn timber

    Författare :Nils Lundgren; Olle Hagman; Gary Schajer; Luleå tekniska universitet; []
