3. 17. On Strategy and Manufacturing Flexibility

   Författare :Carl-Henric Nilsson; Företagsekonomiska institutionen; []
   Nyckelord :Multi-methodology.; Strategic alliance; Capital-back; Uncertainty; Strategic flexibility; Manufacturing strategy; Manufacturing flexibility; Strategy;

   Sammanfattning : The era when customers bought what companies produced is long gone. The situation is now reversed and companies must produce what customers want; while the customers' preferences are, furthermore, becoming increasingly diverse. This has forced companies to adopt a new mode of thinking in order to survive. LÄS MER

   Nyckelord :advantage-seeking; decision-making; entrepreneurial action; internal organizational factors; networks; new ventures; opportunity-seeking; strategic action; strategic entrepreneurship; Business Studies; Företagsekonomi;

   Sammanfattning : This thesis investigates how firms act entrepreneurially and strategically in heavily regulated sectors. Over four studies, the thesis develops a deeper and more empirically grounded understanding of how entrepreneurial and strategic actions are developed and combined. LÄS MER

5. 19. Productivity and carbon transfer in pelagic food webs in response to carbon, nutrients and light

   Författare :Carolyn Faithfull; Ann-Kristin Bergström; Tobias Vrede; Kathryn Cottingham; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial production; phytoplankton production; mesocosms; food webs; carbon; nutrients; light; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; limnologi; Limnology;

   Sammanfattning : Some of the major problems we face today are human induced changes to the nitrogen (N), phosphorus (P) and carbon (C) cycles. Predicted increases in rainfall and temperature due to climate change, may also increase dissolved organic matter (DOM) inflows to freshwater ecosystems in the boreal zone. LÄS MER

7. 20. Semantic Framing of Speech : Emotional and Topical Cues in Perception of Poorly Specified Speech

   Författare :Björn Lidestam; Björn Lyxell; Staffan Hygge; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech perception; speechreading; facial expressions; priming; phonemes; semantics; lipreading; auditory perception; cognition; paralinguistics; emotional content; Läppavläsning; Psychology; Psykologi;

   Sammanfattning : The general aim of this thesis was to test the effects of paralinguistic (emotional) and prior contextual (topical) cues on perception of poorly specified visual, auditory, and audiovisual speech. The specific purposes were to (1) examine if facially displayed emotions can facilitate speechreading performance; (2) to study the mechanism for such facilitation; (3) to map information-processing factors that are involved in processing of poorly specified speech; and (4) to present a comprehensive conceptual framework for speech perception, with specification of the signal being considered.
