Large-scale variations of the dust optical properties in the Galaxy
We present an analysis of the dust optical properties at large scale, for the
whole galactic anticenter hemisphere. We used the 2MASS Extended Source Catalog
to obtain the total reddening on each galaxy line of sight and we compared this
value to the IRAS 100 microns surface brightness converted to extinction by
Schlegel et al (1998). We performed a careful examination and correction of the
possible systematic effects resulting from foreground star contamination,
redshift contribution and galaxy selection bias. We also evaluated the
contribution of dust temperature variations and interstellar clumpiness to our
method. The correlation of the near-infrared extinction to the far-infrared
optical depth shows a discrepancy for visual extinction greater than 1 mag with
a ratio A_V(FIR) / A_V(gal) = 1.31 +- 0.06. We attribute this result to the
presence of fluffy/composite grains characterized by an enhanced far--infrared
emissivity. Our analysis, applied to half of the sky, provides new insights on
the dust grains nature suggesting fluffy grains are found not only in some very
specific regions but in all directions for which the visual extinction reaches
about 1 mag.Comment: 10 pages, 11 figures, accepted for publication in A&
Moving Beyond Brands: Integrating Approaches to Mediation
A briefer version of this article was published in the Alaska Justice Forum:
"Moving Beyond Brands: Integrating Approaches to Mediation" by Brian Jarrett. Alaska Justice Forum 29(3â4): 1, 9â12 (Fall 2012/Winter 2013). (https://www.uaa.alaska.edu/academics/college-of-health/departments/justice-center/alaska-justice-forum/29/3-4fall2012winter2013/a_mediation.cshtml).Mediation has become a competition among brands vying for distinction based more on market concerns than genuine difference. This is not a positive development for a professional field of endeavor. Mediation has much more to offer than competing claims of superiority that attempt to deride and disparage the competition. This article, which is written from a sociological viewpoint, challenges these claims and suggests that the mediation community should develop instead a broader integrated approach to mediation that is pragmatic, flexible, open-source, and based on a robust theoretical foundation.Introduction /

The chemical signature of surviving Population III stars in the Milky Way
Cosmological simulations of Population (Pop) III star formation suggest that
the primordial initial mass function may have extended to sub-solar masses. If
Pop III stars with masses < 0.8 M_Sun did form, then they should still be
present in the Galaxy today as either main sequence or red giant stars. Despite
broad searches, however, no primordial stars have yet been identified. It has
long been recognized that the initial metal-free nature of primordial stars
could be masked due to accretion of metal-enriched material from the
interstellar medium (ISM). Here we point out that while gas accretion from the
ISM may readily occur, the accretion of dust from the ISM can be prevented due
to the pressure of the radiation emitted from low-mass stars. This implies a
possible unique chemical signature for stars polluted only via accretion,
namely an enhancement in gas phase elements relative to those in the dust
phase. Using Pop III stellar models, we outline the conditions in which this
signature could be exhibited, and we derive the expected signature for the case
of accretion from the local ISM. Intriguingly, due to the large fraction of
iron depleted into dust relative to that of carbon and other elements, this
signature is similar to that observed in many of the so-called carbon-enhanced
metal-poor (CEMP) stars. We therefore suggest that some fraction of the
observed CEMP stars may, in fact, be accretion-polluted Pop III stars.Comment: 9 pages, 9 figures, 1 table; accepted for publication in MNRA
The Effect of Dust Extinction on the Observed Properties of Galaxies in the Near-Infrared
Galaxies behind the Milky Way suffer size reduction and dimming due to their
obscuration by dust in the disk of our Galaxy. The degree of obscuration is
wavelength dependent. It decreases towards longer wavelengths. Compared to the
optical, the Near InfraRed (NIR) band extinction is only
that of the band. This makes NIR surveys well suited for galaxy surveys
close to the Galactic Plane where extinction is severe.
While Galactic obscuration is less prominent in the NIR it is not negligible.
In this paper we derive empirical relations to correct isophotal radii and
magnitudes of galaxies observed in the NIR for foreground absorption. We
simulate extinction in the , and bands on 64 (unobscured) galaxies
from the 2MASS Large Galaxy Atlas \citep{jarrett}. We propose two methods for
the extinction correction, the first is optimized to provide the most accurate
correction and the second provides a convenient statistical correction that
works adequately in lower extinction regions. The optimized correction utilizes
the galaxy surface brightness, either the disk central surface brightness,
, or the combined disk plus bulge central surface brightness, elliptical
and disk/spiral Hubble types. A detailed comparison between the different
methods and their accuracy is provided.Comment: 9 pages, 8 figures and 8 tables. Accepted by the MNRAS: Accepted 2009

Pension Reforms in Poland and Elsewhere: the View from Paris
Recently several countries, including Estonia, Latvia, Lithuania, Hungary, Poland, Romania and Slovakia, have at least partially reversed their earlier moves towards compulsory defined-contribution schemes. This paper concentrates on Poland, which just reduced contributions going to the mandatory second pillar from 7.3 to 2.3% of earnings with that amount diverted to the public pension regime (ZUS). Trying to solve the problem of public finance sustainability by radically shrinking the second tier of the pension system has obvious costs in terms of poverty among old-age pensioners. Their incomes will fall sharply relative to those of working-age population. Partially reversing pension reform will also cost Poland in terms of risk spreading and capital market development. It will also undermine the populationâs trust in the system. There is no alternative for achieving public finance sustainability but to restrain current spending and/or raise taxes. The pensionable age should be raised further (probably to 70 by mid-century), even in the general scheme, to deal with the long-run demographic challenge and be equalized across the two sexes. The authorities should move to unify pension provision systems, in particular by phasing out the farmersâ regime (KRUS) and making pensions for miners and others with special regimes closer to actuarially neutral.pension system, pension reform, pension adequacy, pension funds, retirement age, replacement age, Poland
