Social Media: the Wild West of CSR Communications

Purpose - The central argument that this paper posits is that traditional media of old presented a clear, ordered world of communication management for organisations to extol their CSR credentials. In contrast to this, new Web 2.0 social media is increasingly being used by activists and hactivists to challenge corporate communication CSR messages and does so by highlighting instances and examples of Corporate Social Irresponsibility (CSI) (Jones, Bowd and Tench, 2009; Tench, Sun and Jones, 2012). Design/methodology/approach - The paper reports on research data from the European Communication Monitor 2010, 2011 and 2012 (http://www.communicationmonitor.eu/) and draws on work already published in this area (Tench, Verhoeven and Zerfass, 2009; Verhoeven et al, 2012; and Zerfass et al, 2010, 2011) to illustrate the unruly unregulated Web 2.0 social media communication landscape in Europe. A range of literature is drawn on to provide the theoretical context for an exploration of issues that surround social media. Findings - In late modernity (Giddens, 1990) communication comes in many guises. Social media is one guise and it has re-shaped as well as transformed the nature of communications and the relationship between organisations and their stakeholders. Originality/value - Communicating CSR in the Wild West of social media requires diplomatic and political nous, as well as awareness and knowledge of the dangers and pitfalls of CSI. The data reported on in this paper illustrates well the above points and sets out scenarios for future development of corporate communication of CSR through, and with social media

Swimming of a sphere in a viscous incompressible fluid with inertia

The swimming of a sphere immersed in a viscous incompressible fluid with inertia is studied for surface modulations of small amplitude on the basis of the Navier-Stokes equations. The mean swimming velocity and the mean rate of dissipation are expressed as quadratic forms in term of the surface displacements. With a choice of a basis set of modes the quadratic forms correspond to two hermitian matrices. Optimization of the mean swimming velocity for given rate of dissipation requires the solution of a generalized eigenvalue problem involving the two matrices. It is found for surface modulations of low multipole order that the optimal swimming efficiency depends in intricate fashion on a dimensionless scale number involving the radius of the sphere, the period of the cycle, and the kinematic viscosity of the fluid.Comment: 19 pages, 4 figure

Optimal translational swimming of a sphere at low Reynolds number

Swimming velocity and rate of dissipation of a sphere with surface distortions are discussed on the basis of the Stokes equations of low Reynolds number hydrodynamics. At first the surface distortions are assumed to cause an irrotational axisymmetric flow pattern. The efficiency of swimming is optimized within this class of flows. Subsequently more general axisymmetric polar flows with vorticity are considered. This leads to a considerably higher maximum efficiency. An additional measure of swimming performance is proposed based on the energy consumption for given amplitude of stroke.Comment: 34 pages, 12 figure

Third Harmonic Cavity Modal Analysis

Third harmonic cavities have been designed and fabricated by FNAL to be used at the FLASH/XFEL facility at DESY to minimise the energy spread along the bunches. Modes in these cavities are analysed and the sensitivity to frequency errors are assessed. A circuit model is employed to model the monopole bands. The monopole circuit model is enhanced to include successive cell coupling, in addition to the usual nearest neighbour coupling. A mode matching code is used to facilitate rapid simulations, incorporating fabrication errors. Curves surfaces are approximated by a series of abrupt transitions and the validity of this approach is examinedComment: Proceedings of 14th International Conference on RF Superconductivity (SRF 2009), 2009, Berlin, German

Induced Gravity II: Grand Unification

As an illustration of a renormalizable, asymptotically-free model of induced gravity, we consider an $SO(10)$ gauge theory interacting with a real scalar multiplet in the adjoint representation. We show that dimensional transmutation can occur, spontaneously breaking $SO(10)$ to $SU(5){\otimes}U(1),$ while inducing the Planck mass and a positive cosmological constant, all proportional to the same scale $v$. All mass ratios are functions of the values of coupling constants at that scale. Below this scale (at which the Big Bang may occur), the model takes the usual form of Einstein-Hilbert gravity in de Sitter space plus calculable corrections. We show that there exist regions of parameter space in which the breaking results in a local minimum of the effective action, and a {\bf positive} dilaton $(\hbox{mass})^2$ from two-loop corrections associated with the conformal anomaly. Furthermore, unlike the singlet case we considered previously, some minima lie within the basin of attraction of the ultraviolet fixed point. Moreover, the asymptotic behavior of the coupling constants also lie within the range of convergence of the Euclidean path integral, so there is hope that there will be candidates for sensible vacua. Although open questions remain concerning unitarity of all such renormalizable models of gravity, it is not obvious that, in curved backgrounds such as those considered here, unitarity is violated. In any case, any violation that may remain will be suppressed by inverse powers of the reduced Planck mass.Comment: 44 pages, 5 figures, 2 tables. v2 has new discussion concerning stability of SSB plus related appendix.
