Correlated event-by-event fluctuations of flow harmonics in Pb-Pb Collisions at √sNN = 2.76 TeVALICE Collaboration; Barnby, Lee; European Organization for Nuclear Research (CERN); University of Birmingham (American Physical Society, 2016-10-28)We report the measurements of correlations between event-by-event fluctuations of amplitudes of anisotropic flow harmonics in nucleus-nucleus collisions, obtained for the first time using a new analysis method based on multiparticle cumulants in mixed harmonics. This novel method is robust against systematic biases originating from nonflow effects and by construction any dependence on symmetry planes is eliminated. We demonstrate that correlations of flow harmonics exhibit a better sensitivity to medium properties than the individual flow harmonics. The new measurements are performed in Pb-Pb collisions at the center-of-mass energy per nucleon pair of √sNN=2.76 TeV by the ALICE experiment at the Large Hadron Collider. The centrality dependence of correlation between event-by-event fluctuations of the elliptic v2 and quadrangular v4 flow harmonics, as well as of anticorrelation between v2 and triangular v3 flow harmonics are presented. The results cover two different regimes of the initial state configurations: geometry dominated (in midcentral collisions) and fluctuation dominated (in the most central collisions). Comparisons are made to predictions from Monte Carlo Glauber, viscous hydrodynamics, ampt, and hijing models. Together with the existing measurements of the individual flow harmonics the presented results provide further constraints on the initial conditions and the transport properties of the system produced in heavy-ion collisions.
Event portfolio management: theory and methods for event management and tourismAntchak, Vladimir; Ziakas, Vassilios; Getz, Donald; University of Derby; Plymouth Marjon University; University of Calgary (Goodfellow, 2019-09-05)Event Portfolio Management' explores the phenomenon of the event portfolio as a policy tool for cities and destinations. Divided into two parts – ‘Theory’ and ‘Practice’ – the book critically analyses and summarises key underpinnings behind portfolio theory development and identifies key trends and issues in the event portfolio approach. It examines the processes of event portfolio development and management, leveraging, stakeholder networking and collaboration, portfolio design, risk assessment and evaluation. With a wide geographical reach, the book introduces the results of empirical research from different international case studies, including Auckland, Wellington and Dunedin in New Zealand, Canberra and Melbourne in Australia, and Manchester and Edinburgh in the UK.
