    This paper and its findings suggest there is little organised life-long learning in public relations and communication management in Europe. Consequently senior communication practitioners believe there are major failings in the capabilities related to our profession which if not addressed will serve as significant challenges for European organisations over the next 10 years. Longitudinal research further suggests the role of practitioners is changing and they require many more competencies to be successful in their communication roles (Zerfass et al., 2007- 2013). These are some of the observations and conclusions drawn from and supported by an extensive review of theory and practice emerging from the ECOPSI Programme (European Communication Professional Skills and Innovation), which is the largest European Union funded project of its kind to report into strategic communication until now (Tench et al 2012, 2013a, 2013b). There are on-going gaps and deficiencies in the development of the individuals as well as broad variation in how practitioners identify needs and access appropriate interventions. This presents numerous opportunities for deeper and on-going professional training and development to build consistency and support good practice in moving away from a hands-on, learning on-the-job approach to more focused knowledge acquisition and development. The ECOPSI programme is a two-year research project exploring the competencies required by communication professionals in Europe. This innovative programme is a partnership of six leading European universities in communication research and education located in Germany, Netherlands, Slovenia, Spain, Turkey and the UK as well as the European Association of Communication Directors (EACD). The two-year programme is led by Leeds Metropolitan University and is the first and largest to be funded by the European Union. The study provides in-depth insights into the competencies needed for four communication roles through the Communication Role Matrix: internal communication, crisis communication, social media and chief communication officer (CCO). The Communication Role Matrix captures what it is a communication professional does and the requirement necessary to perform the role successfully by identifying the knowledge, skills (hard and soft) and personal attributes for each role (Tench et al 2013a). This paper: (1) analyses the construction and perceptions about the Communication Role Matrix; (2) highlights current contemporary issues faced by the industry; and (3) presents the transference of knowledge from ECOPSI to the professional field through the Portal (for) Advancing Communication Expertise (p4ace) along with a self-diagnostic tool aimed to engage practitioners in continued professional development

    First Disk-Resolved Millimeter Observations Of Io's Surface And SO2 Atmosphere

    Aims. In spite of considerable progress in the last two decades, Io's atmosphere remains poorly understood. The goal of this work is to improve our understanding of its spatial distribution, temperature and dynamics. Methods. We present millimeter observations of Io's surface and SO2 atmosphere at 1.4 mm obtained with the IRAM Plateau de Bure Interferometer in January-February 2005. With a synthesized beam of 0.5 x 1.5 '', these observations resolve Io's similar to 1.0 '' disk in the longitudinal/local time direction, and sample the leading and trailing hemispheres of Io. Results. The measured continuum total flux and visibilities show that continuum radiation originates from a depth of at least 1 cm in Io's subsurface. On both the leading and trailing sides, emission in the SO2 216.643 GHz line appears spatially narrower than the continuum, and suggests that the atmosphere covers similar to 80% of the surface on the leading side and similar to 60% on the trailing. On the leading side, disk-resolved spectra yield Doppler shift measurements, indicating a beam-integrated limb-to-limb velocity difference of 330 +/-3 100 m/s in the prograde direction. Such a flow allows an improved fit of disk-averaged SO2 spectra, but its origin remains to be understood. Mean gas temperatures are in the range 130-180 K, in agreement with estimates from IR measurements, and with a tendency for higher trailing vs leading side gas temperatures. On the basis of realistic plume models, we find that the contribution of isolated volcanic plumes to the SO2 emission is small.Astronom

    The 750 GeV Diphoton Excess as a First Light on Supersymmetry Breaking

    Full text link
    One of the most exciting explanations advanced for the recent diphoton excess found by ATLAS and CMS is in terms of sgoldstino decays: a signal of low-energy supersymmetry-breaking scenarios. The sgoldstino, a scalar, couples directly to gluons and photons, with strength related to gaugino masses, that can be of the right magnitude to explain the excess. However, fitting the suggested resonance width, Gamma ~ 45 GeV, is not so easy. In this paper we explore efficient possibilities to enhance the sgoldstino width, via the decay into two Higgses, two Higgsinos and through mixing between the sgoldstino and the Higgs boson. In addition, we present an alternative and more efficient mechanism to generate a mass splitting between the scalar and pseudoscalar components of the sgoldstino, which has been suggested as an interesting alternative explanation to the apparent width of the resonance.Comment: 14 pages, 3 figure

    The Bak-Sneppen Model on Scale-Free Networks

    Full text link
    We investigate by numerical simulations and analytical calculations the Bak-Sneppen model for biological evolution in scale-free networks. By using large scale numerical simulations, we study the avalanche size distribution and the activity time behavior at nodes with different connectivities. We argue the absence of a critical barrier and its associated critical behavior for infinite size systems. These findings are supported by a single site mean-field analytic treatment of the model.Comment: 5 pages and 3 eps figures. Final version appeared in Europhys. Let

    Bragg spectroscopy for measuring Casimir-Polder interactions with Bose-Einstein condensates above corrugated surfaces

    Get PDF
    We propose a method to probe dispersive atom-surface interactions by measuring via two-photon Bragg spectroscopy the dynamic structure factor of a Bose-Einstein condensate above corrugated surfaces. This method takes advantage of the condensate coherence to reveal the spatial Fourier components of the lateral Casimir-Polder interaction energy.Fil: Moreno, Gustavo Ariel.
