1. 1. With Lives on the Line : How Users Respond to a Highly Mandated Information System Implementation - A Longitudinal Study

   Författare :Andreas Hedrén; Pär Ågerfalk; Franck Tétard; James Sallis; Susan A. Brown; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; attitude; mandates; use; longitudinal; healthcare; information systems; Information Systems; Informationssystem;

   Sammanfattning : Some people are forced to use a specific technology in their work. Should they resist, people die. This thesis examines the implementation of a Patient Data Management System for the critical care departments at two Swedish hospitals. The degree of mandate to use a technology varies along a spectrum anchored between none and absolute. LÄS MER

3. 2. Development of a new service-oriented modelling method for information systems analysis and design

   Författare :Prima Gustiené; Anders G Nilsson; Sten Carlsson; William Wei Song; Karlstads universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Information systems analysis and design; conceptual modeling; service orientation; semantic integrity; static and dynamic aspects; goal modeling.; Informatics; Informatik; Information Systems; Informatik;

   Sammanfattning : This thesis presents a new modelling method for information systems analysis and design, where the concept of service and the principles of service orientation are used for integrated modelling and reasoning about information systems architectures across organisational and technical systems boundaries. The concept of service enables cohesion of the intersubjective and objective modelling traditions by using a single type of diagram that facilitates detection of semantic inconsistency, incompleteness, ambiguity and discontinuity between the static and dynamic aspects of information systems specifications.

4. 3. Implementation Methodology in Action : A Study of an Enterprise Systems Implementation Methodology

   Författare :Daniela Mihailescu; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; Enterprise Systems; implementation methodology; AcceleratedSAP; Implementation methodology; Action framework; Software engineering; Programvaruteknik; Economic Information Systems; Ekonomiska informationssystem; iplementation methodology; method in action; Informatics; Informatik;

   Sammanfattning : Enterprise Systems create new opportunities but also new challenges and difficulties for implementers and users. The clear distinction between the development and the implementation of Enterprise Systems Software seems to influence not only the characteristics of methodologies but also how implementers use the Enterprise Systems implementation methodologies.

5. 4. Organization of information pathways in complex networks

   Författare :Atieh Mirshahvalad; Martin Rosvall; Santo Fortunato; Umeå universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Complex systems; Complex Networks; Information; Communication; Community Detection; Significance Analysis; Resampling; Information Spreading.; computer and systems sciences; data- och systemvetenskap;

   Sammanfattning : A shuman beings, we are continuously struggling to comprehend the mechanism of dierent natural systems. Many times, we face a complex system where the emergent properties of the system at a global level can not be explained by a simple aggregation of the system's components at the micro-level. LÄS MER

7. 5. Structural studies of proteins in apoptosis and lipid signaling

   Författare :Maria Dolores Herman Moreno; Pär Nordlund; Markus Gruetter; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; proteins; crystal structure; apoptosis; cancer; CoFi-Blot; kinases; lipid signaling; Structural biology; Strukturbiologi; Structural Biology; strukturbiologi;

   Sammanfattning : Signaling pathways control the fate of the cell. For example, they promote cell survival or commit the cell to death (apoptosis) in response to cell injury or developmental stimuli, decisions, which are vital for the proper development and functioning of metazoan. LÄS MER
