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

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

    Abstract : 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. READ MORE

  5. 3. Duplicate systems : investigating unintended consequences of information technology in organizations

    Abstract : The organizational consequences of information technology (IT) constitutes a core focus in information systems (IS) research. The relationship between organizations and IT has received considerable attention by IS researchers in order to develop knowledge related to how and why organizations and IT are related. READ MORE

  6. 4. Prediction of Mobile Radio Channels : Modeling and Design

    Author : Torbjörn Ekman; Rodney Vaughan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; mobile radio channel; fading; channel model; channel estimation; channel prediction; power prediction; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Abstract : Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation and fast link adaptation. This thesis deals with linear prediction of the complex impulse response of a channel and unbiased quadratic prediction of the power. READ MORE

  7. 5. A-type Potassium Channels in Dendritic Integration : Role in Epileptogenesis

    Author : Jenny Tigerholm; Erik Fransén; Fredrik Elinder; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; epileptogenesis; fast ripples; synchronicity; dendritic potentials; transient A–type potassium current; KV 4.2; Computer and systems science; Data- och systemvetenskap;

    Abstract : During cognitive tasks, synchronicity of neural activity varies and is correlated with performance. However, there may be an upper limit to normal synchronised activity – specifically, epileptogenic activity is characterized byexcess spiking at high synchronicity. READ MORE
