Corporate Social (Ir)Responsibility in Media and Communication Industries
Microsoft is the most socially responsible company in the world, followed by Google on rank 2 and The Walt Disney Company on rank 3 – at least according to the perceptions of 47,000 people from 15 countries that participated in a survey conducted by the consultancy firm Reputation Institute. In this paper I take a critical look at Corporate Social Responsibility in media and communication industries. Within the debate on CSR media are often only discussed in regard to their role of raising awareness and enabling public debate about corporate social responsibility. What is missing are theoretical and empirical studies about the corporate social (ir)responsibility of media and communication companies themselves. This paper contributes to overcoming this blind spot. First I systematically describe four different ways of relating profit goals and social goals of media and communication companies. I argue for a dialectical perspective that considers how profit interests and social responsibilities mutually shape each other. Such a perspective can draw on a critical political economy of media and communication. Based on this approach I take a closer look at Microsoft, Google and The Walt Disney Company and show that their actual practices do not correspond to their reputation. This analysis points at flaws in the concept CSR. I argue that despite these limitations CSR still contains a rational element that can however only be realised by going beyond CSR. I therefore suggest a new concept that turns CSR off its head and places it upon its feet
The Singularities of the Wave Trace of the Basic Laplacian of a Riemannian Foliation
We apply techniques of microlocal analysis to the study of the transverse
geometry of Riemannian foliations in order to analyze spectral invariants of
the basic Laplacian acting on functions on a Riemannian foliation with a
bundle-like metric. In particular, we consider the trace of the basic wave
operator when the mean curvature form is basic. We extend the concept of basic
functions to distributions and demonstrate the existence of the basic wave
kernel. The singularities of the trace of this basic wave kernel occur at the
lengths of certain geodesic arcs which are orthogonal to the closures of the
leaves of the foliation. In cases when the foliation has regular closure, a
complete representation of the trace of the basic wave kernel can be computed
for . Otherwise, a partial trace formula over a certain set of lengths
of well-behaved geodesic arcs is obtained
A Method to Separate Stochastic and Deterministic Information from Electrocardiograms
In this work we present a new idea to develop a method to separate stochastic
and deterministic information contained in an electrocardiogram, ECG, which may
provide new sources of information with diagnostic purposes. We assume that the
ECG has information corresponding to many different processes related with the
cardiac activity as well as contamination from different sources related with
the measurement procedure and the nature of the observed system itself. The
method starts with the application of an improuved archetypal analysis to
separate the mentioned stochastic and deterministic information. From the
stochastic point of view we analyze Renyi entropies, and with respect to the
deterministic perspective we calculate the autocorrelation function and the
corresponding correlation time. We show that healthy and pathologic information
may be stochastic and/or deterministic, can be identified by different measures
and located in different parts of the ECG.Comment: 4 pages, 6 figure
Electron correlations in a C fullerene cluster: A lattice density-functional study of the Hubbard model
The ground-state properties of C fullerene clusters are determined in
the framework of the Hubbard model by using lattice density-functional theory
(LDFT) and scaling approximations to the interaction-energy functional. Results
are given for the ground-state energy, kinetic and Coulomb energies, local
magnetic moments, and charge-excitation gap, as a function of the Coulomb
repulsion and for electron or hole doping close half-band
filling (). The role of electron correlations is analyzed by
comparing the LDFT results with fully unrestricted Hartree-Fock (UHF)
calculations which take into account possible noncollinear arrangements of the
local spin-polarizations. The consequences of the spin-density-wave symmetry
breaking, often found in UHF, and the implications of this study for more
complex fullerene structures are discussed.Comment: 18 pages, 7 figures, Submitted to PR
CNS Control of Glucose Metabolism: Response to Environmental Challenges
Over the last 15 years, considerable work has accumulated to support the role of the CNS in regulating postprandial glucose levels. As discussed in the first section of this review, the CNS receives and integrates information from afferent neurons, circulating hormones, and postprandially generated nutrients to subsequently direct changes in glucose output by the liver and glucose uptake by peripheral tissues. The second major component of this review focuses on the effects of external pressures, including high fat diet and changes to the light:dark cycle on CNS-regulating glucose homeostasis. We also discuss the interaction between these different pressures and how they contribute to the multifaceted mechanisms that we hypothesize contribute to the dysregulation of glucose in type 2 diabetes mellitus (T2DM). We argue that while current peripheral therapies serve to delay the progression of T2DM, generating combined obesity and T2DM therapies targeted at the CNS, the primary site of dysfunction for both diseases, would lead to a more profound impact on the progression of both diseases
