Corporate communications: audiences, funding and crisis management
Who are the key audiences of corporate communications? Is the communication department adequately funded? And how are crisis handled? This paper reports an empirical research conducted in 20 British organisations, with a focus on these three questions. It is found that internal publics, financial PR and opinion formers are viewed as the three most important audiences. Although most organisations now are more conscious of their corporate identity than ever before, the function is generally funded inadequately

Corporate communications in practice: the profile of pr directors in the british companies
In spite of being seen as an increasingly important function of management, public relations (PR) or corporate communications (as is called in this paper) remains a subject which is seriously under-researched. This paper reports an empirical study conducted in 20 British organisations with a focus on the director of corporate communications. It examines the origin and role of corporate communication executives and identifies those essential characteristics that constitute the most successful communication practitioners

Is Corporate Communications A Strategic Function?
Corporate communications, or public relations (PR) as hitherto it has largely been known, has become an increasingly important function in business organisations. Yet little has been published on the role and function of communication executives. This paper reports an empirical study conducted in 20 British organisations with a focus on the director of corporate communications. It examines the role and tasks of corporate communication executives and discusses their status within organisational structure and the impact of corporate communications upon the strategic planning process
Accurate photometry of extended spherically symmetric sources
We present a new method to derive reliable photometry of extended spherically
symmetric sources from {\it HST} images (WFPC2, ACS/WFC and NICMOS/NIC2
cameras), extending existing studies of point sources and marginally resolved
sources. We develop a new approach to accurately determine intrinsic sizes of
extended spherically symmetric sources, such as star clusters in galaxies
beyond the Local Group (at distances <~ 20 Mpc), and provide a detailed
cookbook to perform aperture photometry on such sources, by determining
size-dependent aperture corrections (ACs) and taking sky oversubtraction as a
function of source size into account. In an extensive Appendix, we provide the
parameters of polynomial relations between the FWHM of various input profiles
and those obtained by fitting a Gaussian profile (which we have used for
reasons of computational robustness, although the exact model profile used is
irrelevant), and between the intrinsic and measured FWHM of the cluster and the
derived AC. Both relations are given for a number of physically relevant
cluster light profiles, intrinsic and observational parameters. AC relations
are provided for a wide range of apertures. Depending on the size of the source
and the annuli used for the photometry, the absolute magnitude of such extended
objects can be underestimated by up to 3 mag, corresponding to an error in mass
of a factor of 15. We carefully compare our results to those from the more
widely used DeltaMag method, and find an improvement of a factor of 3--40 in
both the size determination and the AC.Comment: The paper is accepted for publication in A&A, Section 13
(Observational Techniques, published electronically). The published version
contains one example table per appendix. A version of the paper containing
all tables as well as all data in electronical form are available

The use of imaging systems to monitor shoreline dynamics
The development of imaging systems is nowadays established as one of the most powerful and reliable tools for monitoring beach morphodynamics. Two different techniques for shoreline detection are presented here and, in one case, applied to the study of beach width oscillations on a sandy beach (Pauanui Beach, New Zealand). Results indicate that images can provide datasets whose length and sample interval are accurate enough to resolve inter-annual and seasonal oscillations, and long-term trends. Similarly, imaging systems can be extremely useful in determining the statistics of rip current occurrence. Further improvements in accuracy and reliability are expected with the recent introduction of digital systems
First Results From the Large Binocular Telescope: Deep Photometry of New dSphs
This contribution describes photometry for two Galactic dSphs obtained with
the Large Binocular Telescope to a magnitude of ~25.5. Using the Large
Binocular Camera, a purpose-built wide-field imager for the LBT, we have
examined the structure and star formation histories of two newly-discovered
Local Group members, the Hercules dSph and the Leo T dSph/dIrr system. We have
constructed a structural map for the Hercules system using three-filter
photometry to V ~ 25.5. This is the first deep photometry for this system, and
it indicates that Hercules is unusually elongated, possibly indicating
distortion due to the Galactic tidal field. We have also derived the first star
formation history for the Leo T system, and find that its oldest population of
stars (age ~ 13 Gyr) were relatively metal-rich, with [Fe/H] ~ -1.5.Comment: Four pages, two figures. To appear in the proceedings of "Galaxies in

Carbon pricing and the elasticity of CO2 emissions
We study the impact of carbon pricing on CO2emissions across five sectors for a panel of 39 countries over 1990-2016. Using newly constructed sector-level carbon price data, we implement a novel approach to estimate the changes in CO2emissions associated with (i) the introduction of carbon pricing regardless of the price level; (ii) the implementation effect as a function of the price level; and (iii) post-implementation marginal changes in the CO2price.We find that the introduction of carbon pricing has reduced growth in CO2emissions by 1% to 2.5% on average relative to counterfactual emissions, with most abatement occurring in the electricity and heat sector. Exploiting variation in carbon pricing to explain heterogeneity in treatment effects, we find an imprecisely estimated semi-elasticity of a 0.05% reduction in emissions growth per average 1/tCO2 has temporarily lowered the growth rate of CO2emissions by around 0.01%. These are disappointingly small effects. Simulating potential future emissions reductions in response to carbon price paths, we conclude that âin the absence of complementary non-pricing policy interventions â carbon pricing alone, even if implemented globally, is unlikely to be sufficient to achieve emission reductions consistent with the Paris climate agreement
