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(3–4): 1, 9–12 (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 / I.

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

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 population’s 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 farmers’ 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

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) $K_s$ band extinction is only $\approx10$ that of the $B$ 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 $J$, $H$ and $K_s$ 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, $\mu_0$, 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 September 18.

Engagement in Authentic Geoscience Research: Evaluation of Research Experiences of Undergraduates and Secondary Teachers

This article examines the effects of a program involving authentic research on the participants' interest in research, career plans, and attitudes on science. The findings are from the first year of a three-year program funded by the National Science Foundation Research Experiences for Undergraduates program. In three out of four projects, participants increased their interest in research, with two-thirds planning to change career plans to become more research-oriented. The implications of these findings for providing authentic research opportunities are discussed. Educational levels: Graduate or professional

Administrative automation in a scientific environment

Although the scientific personnel at GSFC were advanced in the development and use of hardware and software for scientific applications, resistance to the use of automation or purchase of terminals, software and services, specifically for administrative functions was widespread. The approach used to address problems and constraints and plans for administrative automation within the Space and Earth Sciences Directorate are delineated. Accomplishments thus far include reduction of paperwork and manual efforts; improved communications through telemail and committees; additional support staff; increased awareness at all levels on ergonomic concerns and the need for training; better equipment; improved ADP skills through experience; management commitment; and an overall strategy for automating

The Early Growth of the First Black Holes

With detections of quasars powered by increasingly massive black holes (BHs) at increasingly early times in cosmic history over the past decade, there has been correspondingly rapid progress made on the theory of early BH formation and growth. Here we review the emerging picture of how the first massive BHs formed from the primordial gas and then grew to supermassive scales. We discuss the initial conditions for the formation of the progenitors of these seed BHs, the factors dictating the initial masses with which they form, and their initial stages of growth via accretion, which may occur at super-Eddington rates. Finally, we briefly discuss how these results connect to large-scale simulations of the growth of supermassive BHs over the course of the first billion years following the Big Bang.Comment: 13 pages, 9 figures, invited review accepted for publication in PAS
