  1. 1. Cluster Initiatives as Intermediaries : A Study of their Management and Stakeholders

    Författare :Inessa Laur; Magnus Klofsten; Dzamila Bienkowska; Peter Van der Sijde; Linköpings universitet; []
    Nyckelord :Cluster; cluster initiatives; intermediary organization; regional development; entrepreneurship; success factors; actors stakeholders and activities;

    Sammanfattning : This dissertation offers a platform to understand the nature of cluster initiatives as a socio-economic phenomenon combining cluster, entrepreneurship and intermediary features. They are particular types of ventures facilitating networks and dialog platforms adjusted to local contexts and offering a way to enhance regional development. LÄS MER

  3. 2. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

    Författare :Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER

  4. 3. Quantum Chemical Cluster Modeling of Enzymatic Reactions

    Författare :Rongzhen Liao; Fahmi Himo; Robert Deeth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cluster approach; density functional theory; B3LYP; enzyme; mechanism; dinuclear; trinuclear; zinc; tungsten; hydrolysis; decarboxylation; formaldehyde oxidation; hydration; methyl transfer; Quantum chemistry; Kvantkemi; organisk kemi; Organic Chemistry;

    Sammanfattning : The Quantum chemical cluster approach has been shown to be quite powerful and efficient in the modeling of enzyme active sites and reaction mechanisms. In this thesis, the reaction mechanisms of several enzymes have been investigated using the hybrid density functional B3LYP. LÄS MER

  5. 4. Metabolomics and proteomics studies of brain tumors : a chemometric bioinformatics approach

    Författare :Lina Mörén; Henrik Antti; Anders Malmendal; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioblastoma; glioma; meningioma; metabolomics; proteomics; mass-spectrometry; biologisk kemi; biological chemistry;

    Sammanfattning : The WHO classification of brain tumors is based on histological features and the aggressiveness of the tumor is classified from grade I to IV, where grade IV is the most aggressive. Today, the correlation between prognosis and tumor grade is the most important component in tumor classification. LÄS MER

  7. 5. Cluster Dynamics and Industrial Policy in Peripheral Regions : a study of cluster formation as a local development process

    Författare :Cali Nuur; Staffan Laestadius; David Jacobson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peripheral regions; Industrial policy; regional development policy; cluster dynamics; call centress; Sweden; Hälsingland; Landsortsregioner; Industriell politik; Regional utvecklingspolitik; Klusterdynamik; Call centers; Sverige; Hälsingland; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Sammanfattning : The rapid growth of the global economy in the last two decades has created a new economic reality in many municipalities in peripheral regions of Sweden. Having earlier relied on traditional industry as the source of employment, today municipalities in peripheral regions are struggling to survive in a completely changed economic landscape, with new conditions for development.
