    Dehmamy, Nima; Buldyrev, Sergey; Havlin, Shlomo; Stanley, Harry Eugene; Vodenska, Irena (2016-09-19)
    We analyze the linear response of a market network to shocks based on the bipartite market model we introduced in an earlier paper, which we claimed to be able to identify the time-line of the 2009-2011 Eurozone crisis ...
  • Learning to improvise, or improvising to learn: knowledge generation and ‘innovative practice’ in project environments 

    Leybourne, Stephen; Kennedy, Monica (Wiley, 2015-01)
    This paper considers the links between knowledge management, improvisational working and project management, highlighting their confluence in a number of key dimensions and focusing on the way new knowledge is generated, shared, ...
  • Project knowledge into project practice: generational issues in the knowledge management process 

    Leybourne, Stephen; Bernardin, Emmanuelle
    This paper considers Learning and Knowledge Transfer within the project domain. Knowledge can be a tenuous and elusive concept, and is challenging to transfer within organizations and projects. This challenge is compounded ...

    Piskorec, Matija; Antulov-Fantulin, Nino; Novak, Petra Kralj; Mozetic, Igor; Grcar, Miha; Vodenska, Irena; Smuc, Tomislav (NATURE PUBLISHING GROUP, 2014-05-22)
    Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news ...
  • Cascading failures in bi-partite graphs: model for systemic risk propagation 

    Huang, Xuqing; Vodenska, Irena; Havlin, Shlomo; Stanley, H. Eugene (NATURE PUBLISHING GROUP, 2013-02-05)
    As economic entities become increasingly interconnected, a shock in a financial network can provoke significant cascading failures throughout the system. To study the systemic risk of financial systems, we create a bi-partite ...
  • Geographically weighted regression in the analysis of the development of information and communication technology in Indonesia

    Vodenska, Irena; Aoyama, Hideaki; Fujiwara, Yoshi; Iyetomi, Hiroshi; Arai, Yuta (PUBLIC LIBRARY SCIENCE, 2016-03-15)
    We explore the foreign exchange and stock market networks for 48 countries from 1999 to 2012 and propose a model, based on complex Hilbert principal component analysis, for extracting significant lead-lag relationships ...
