Pricing and quality investments in a mixed brown-green product market
Sustainable Supply Chain Management (SSCM) has assumed
a position of prominence for academics and industry over the last two
decades. The sustainability literature shows that typically manufacturers aim to optimize their pricing and greening level decisions in a mixed
(green and brown) consumer market. In this work, we capture a manufacturer’s classic dilemma on the pricing of green and brown products,
and greening investments, while subject to budget constraint. We compute and analyze the variations of optimal decisions over time. Our findings underscore the importance of investing in greening technologies and
learning for the survival of green products. Furthermore, we show that
a manufacturer’s optimal pricing strategy is to enter the market with
a lower price for the green product and to increase it over time, eventually, surpassing the price for the brown product. Our analysis reveals
that the greening level attraction can nullify the effect of a high price on
the green product, resulting in higher green demand than brown. Higher
green product demand is a win-win situation for both the manufacturer
and the environment

Update on the correlation of the highest energy cosmic rays with nearby extragalactic matter
Data collected by the Pierre Auger Observatory through 31 August 2007 showed
evidence for anisotropy in the arrival directions of cosmic rays above the
Greisen-Zatsepin-Kuz'min energy threshold, \nobreak{eV}. The
anisotropy was measured by the fraction of arrival directions that are less
than from the position of an active galactic nucleus within 75 Mpc
(using the V\'eron-Cetty and V\'eron catalog). An updated
measurement of this fraction is reported here using the arrival directions of
cosmic rays recorded above the same energy threshold through 31 December 2009.
The number of arrival directions has increased from 27 to 69, allowing a more
precise measurement. The correlating fraction is , compared
with expected for isotropic cosmic rays. This is down from the early
estimate of . The enlarged set of arrival directions is
examined also in relation to other populations of nearby extragalactic objects:
galaxies in the 2 Microns All Sky Survey and active galactic nuclei detected in
hard X-rays by the Swift Burst Alert Telescope. A celestial region around the
position of the radiogalaxy Cen A has the largest excess of arrival directions
relative to isotropic expectations. The 2-point autocorrelation function is
shown for the enlarged set of arrival directions and compared to the isotropic
expectation.Comment: Accepted for publication in Astroparticle Physics on 31 August 201
