    We present the first results of our search for transiting exoplanet candidates as part of the Kourovka Planet Search (KPS) project. The primary objective of the project is to search for new hot Jupiters which transit their host stars, mainly in the Galactic plane, in the RcR_c magnitude range of 11 to 14 mag. Our observations were performed with the telescope of the MASTER robotic network, installed at the Kourovka astronomical observatory of the Ural Federal University (Russia), and the Rowe-Ackermann Schmidt Astrograph, installed at the private Acton Sky Portal Observatory (USA). As test observations, we observed three celestial fields of size 2×22\times2 deg2^2 during the period from 2012 to 2015. As a result, we discovered four transiting exoplanet candidates among the 39000 stars of the input catalogue. In this paper, we provide the description of the project and analyse additional photometric, spectral, and speckle interferometric observations of the discovered transiting exoplanet candidates. Three of the four transiting exoplanet candidates are most likely astrophysical false positives, while the nature of the fourth (most promising) candidate remains to be ascertained. Also, we propose an alternative observing strategy that could increase the project's exoplanet haul.Comment: 11 pages, 16 figures; Accepted for publication in Monthly Notices of the Royal Astronomical Society 201

    Consolidated taxonomy and research roadmap for cybercrime and cyberterrorism

    No full text
    In this concluding chapter, we consolidate the broad spectrum of challenges discussed throughout this book towards the formulation of a number key priority topics to be addressed by future research related to cybercrime and cyberterrorism. During this process many of the specific areas that need to be addressed are defined across four interlinked dimensions; technological, regulatory, organisational and human. In the process of identifying the nature of the challenges posed, the scope of the research and initiatives needed in order to progress measures targeting them, as well as the required impacts needed in order to ensure the significance of those initiatives. Initial sections of the chapter recapture, from a definitional perspective, the definitions of cybercrime and its constituent elements towards establishing a harmonised taxonomy of terms that we can use to inform the future work being proposed
