Aphrodite's faces: Toni Morrison's Love and Ethics
This study seeks to examine the ethical import of Morrison's eighth novel, Love (2003), through analysis of its narrative forms. With a complex weaving of narrative voices that offer oppositional points of views, Love demands that readers reconsider what they have been told. By foregrounding narrative ethics as the figurative, as showing rather than telling and signifying, this paper closely examines Love's narrative voices
IceCube Neutrinos from Hadronically Powered Gamma-Ray Galaxies
In this work we use a multi-messenger approach to determine if the high
energy diffuse neutrino flux observed by the IceCube Observatory can originate
from -ray sources powered by Cosmic Rays interactions with gas. Typical
representatives of such sources are Starburst and Ultra-Luminous Infrared
Galaxies. Using the three most recent calculations of the non-blazar
contribution to the extragalactic -ray background measured by the
Fermi-LAT collaboration, we find that a hard power-law spectrum with spectral
index is compatible with all the estimations for the allowed
contribution from non-blazar sources, within 1. Using such a spectrum
we are able to interpret the IceCube results, showing that various classes of
hadronically powered -ray galaxies can provide the dominant
contribution to the astrophysical signal above 100 TeV and about half of the
contribution to the energy flux between 10-100 TeV. With the addition of
neutrinos from the Galactic plane, it is possible to saturate the IceCube
signal at high energy. Our result shows that these sources are still well
motivated candidates.Comment: Accepted for publication on JCA
Corrigendum. Maars to calderas: end-members on a spectrum of explosive volcanic depressions
A corrigendum on
Maars to calderas: end-members on a spectrum of explosive volcanic depressions
by Palladino, D. M., Valentine, G. A., Sottili, G., and Taddeucci, J. (2015). Front. Earth Sci. 3:36.
doi: 10.3389/feart.2015.00036
Reason for Corrigendum:
In the original article (Palladino et al., 2015), there was an error in Figure 1. The vertical axis
of the qualitative plot reported erroneously “ratio of juvenile to lithic materials in deposits outside
of depression”. The correct wording is as follows: “ratio of juvenile to total (i.e., juvenile+lithic)
materials in deposits outside of depression”. In fact, as it was reported correctly in the text, the
amount of juvenilematerial (i.e., scoria or pumice) deposited ouside the different types of explosive
volcanic depressions increases from zero (i.e., no juvenile, all lithic products), as is the case of
hydrothermal (phreatic) explosion craters, to become largely dominant over the lithic component
in the case of ash flow deposits associated with large overpressure collapse calderas. The corrected Figure 1 appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way
Review of The Southwest Airlines Way: Using the Power of relationships to Achieve High Performance by J. H. Gittell.
In The Southwest Airlines Way: Using the Power of Relations to Achieve High Performance, Gittell, an assistant professor of management at Brandeis University and a member of Massachusetts Institute of Technology\u27s Global Airline Industry Program, provides a template of female leadership. Gittell described Southwest Airlines as a gemstone in the industry. After the tragedy of September 11, 2001, Southwest did not layoff employees; yet, the airline showed profit each year. Southwest\u27s 2002 $9 billion total market value was greater than all other major airlines combined (Gittell, 2003, p. 3). Fortune magazine called Southwest the most successful airline in history, praise that coincided with the magazine\u27s affirmation that Southwest is one of 100 best companies to work for in America (p. 3)
