   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex activity; Argumentation Theory; Activity Theory; Logic programming; Knowledge representation; Common-sense reasoning; Artificial Intelligence; business data processing; administrativ databehandling;

   Abstract : The aim of this thesis is to develop theories and formal methods to endow a computing machinery with capabilities to identify, represent, reason and evaluate complex activities that are directed by an individual’s needs, goals, motives, preferences and environment, information which can be inconsistent and incomplete.Current methods for formalising and reasoning about human activity are typically limited to basic actions, e.

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; economies; emerging country sourcing; supply network; interdependencies; involvement; China sourcing.; global sourcing; collaboration; supplier base development; Supplier base;

   Abstract : The aim of this thesis is to explore the initiation and development of a supplier base in a new context from the perspective of a firm. An abductive approach was used to make a case study of the development of a supplier base in China by a Swedish firm, FlexLink. READ MORE

5. 3. Enterprise Social Media in Project-based Knowledge Work : A contextualized view through the lens of activity theory

   Author : Emma Forsgren; Pam McKenzie; Högskolan i Borås; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; enterprise social media; information sharing; activity theory; case study; Library and Information Science; Biblioteks- och informationsvetenskap;

   Abstract : Project-based knowledge work is characterised by decentralised and dynamic team-based structures, different from the tradi­tional, bureaucratic organisation. Arguably, this flexible and collaborative work setting could benefit from enterprise social media, which helps facilitate how people connect, collaborate and share information across organisational boundaries.

   Abstract : Two putative cyclodextrinases (CDases) were amplified from two moderate thermophiles isolated in Iceland: Anoxybacillus flavithermus and Laceyella sacchari. They were cloned, expressed and characterized. The expression of the former was optimized in E. READ MORE

7. 5. Stroke recovery activity-dependent mechanisms

   Author : Miriana Quattromani; Neurokirurgi; []
   Keywords : Stroke recovery; Photothrombosis; Enriched environment; Bioluminescence imaging; Toll-like receptor 2; Microglia; Neurons; Extracellular matrix; Perineuronal nets; Aggrecan; Proteases; Parvalbumin; Resting-state functional connectivity;

   Abstract : Stroke is the leading cause of disability in developed countries and among the major causes of death worldwide. During a stroke, neurons deprived of their normal metabolic substrates cease to function in seconds and show signs of structural damage after only a few minutes which result in the impairment of sensory and motor function.
