   Sammanfattning : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. LÄS MER

   Sammanfattning : The current thesis is based on four individual studies which aim to account for the expression of motion events (ME) in Spanish and Swedish as first languages (L1), in Swedish as a second language (L2), and in Spanish as a heritage language (SHL). The data, resulting from audio-recordings of different sorts of stimuli, have been analyzed with special focus on (1) the most common structures used for referring to various types of ME, (2) the types and amount of information provided by the participants, in particular as regards the semantic components Path, Manner and Ground, and (3) grammatical aspect and types of syntactic structures resorted to, including the correlation between the two latter factors and speakers’ discursive preferences.
