   Författare :Camilla Amft; Stefan Mähl; Elvira Glaser; Mechthild Habermann; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Präteritumschwund; tense; present perfect; preterite; present perfect readings; tense change; tense variation; Early High German; pamphlets; Präteritumschwund; Perfektausweitung; Perfekt; Präteritum; Perfektlesarten; Tempus; Frühneuhochdeutsch; Flugschriften; German; Tyska;

   Sammanfattning : This thesis addresses the decline of the preterite tense, referred to as der Oberdeutsche Präteritumschwund (Upper German Preterite Loss), in favour of the present perfect tense. Its main focus is to examine and compare the distribution of the two tenses. LÄS MER

3. 2. El Pretérito Perfecto Compuesto del español de Chile, Paraguay y Uruguay : Aspectos semánticos y discursivos

   Författare :Carlos Henderson; Johan Falk; Chadwick Howe; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Spanish Present Perfect; basic meaning; type and token reference; temporal indeterminacy; detemporalized ascertainment; aspectual complicity.; Spanish language; Spanska språket; Spanish; spanska;

   Sammanfattning : The aim of the present work is to describe the semantics and the discursive functions from a general cognitivist point of view of the usage of the Present Perfect in the spoken Spanish of Chile, Paraguay and Uruguay. It is argued that cross-linguistic values often ascribed to perfect, such as continuity, current relevance and recency to the speech time –ST– do not offer a consistent view of the actual usage.

4. 3. Participles in Time. The Development of the Perfect Tense in Swedish

   Författare :Ida Larsson; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Scandinavian syntax; Swedish; language change; tense; aspect; perfect; participle; supine; resultative; unaccusativity; auxiliary selection;

   Sammanfattning : This thesis concerns the syntactic-semantic development of the perfect tense from a construction with possessive HAVE and a tenseless participial complement. Both participles and auxiliary are assumed to have internal syntactic structure, and the different perfect-type constructions can thus be related synchronically and diachronically to each other.

5. 4. On perfect simulation and EM estimation

   Författare :Kajsa Larson; Sara Sjöstedt de Luna; Mats Rudemo; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perfect simulation; coupling from the past; Markov chain Monte Carlo; point process; Widom-Rowlinson model; EM algorithm; dispersal distribution; fecundity; first-passage percolation; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

   Sammanfattning : Perfect simulation  and the EM algorithm are the main topics in this thesis. In paper I, we present coupling from the past (CFTP) algorithms that generate perfectly distributed samples from the multi-type Widom--Rowlin-son (W--R) model and some generalizations of it. LÄS MER

7. 5. La Référence au passé dans le dialogue : Étude de l’acquisition de la temporalité chez des apprenants dits avancés de français

   Nyckelord :HUMANIORA; HUMANITIES; language learning; qualified learners; advanced stages of acquisition; individual variation; spoken French; interaction scaffolding; tense and aspect; past time reference; imparfait; perfect; aoriste; Aktionsart; aspectual values; temporal movement; discourse cohesion; French language; Franska språket; French; franska;

   Sammanfattning : The present thesis is a study of past time reference by Swedish university students in interaction with a native speaker of French. Most previous studies in the field of language acquisition have focussed on learners at early stages of acquisition. It is less known how adult, qualified learners use a second language. LÄS MER
