5. 34. Anchoring symbols to sensory data

   Författare :Silvia Coradeschi; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : Intelligent agents embedded in physical environments need the ability to connect, or anchor, the symbols used to perform abstract reasoning to the physical entities which these symbols refer to. Anchoring must deal with indexical and objective references, definite and indefinite identifiers, and a temporary impossibility to perceive physical entities. LÄS MER

7. 35. Management accounting as constructing and opposing customer focus : three case studies on management accounting and customer relations

   Författare :Mikael Cäker; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Computer science; Datavetenskap; Economic Information Systems; Ekonomiska informationssystem; Business and economics; Humanities and Social sciences;

   Sammanfattning : This thesis is on the relation between management accounting and customer focus and relates to discussions about how internal managing processes in organizations are interrelated with interorganizational relations, specifically constructions of customers. Both a normative and a descriptive perspective on the relation are taken within the different parts of the thesis, which consists of a licentiate thesis, three articles and a synthesizing text.
