Life Is Strange and ‘‘Games Are Made’’: A Philosophical Interpretation of a Multiple-Choice Existential Simulator With Copilot Sartre
The multiple-choice video game Life is Strange was described by its French developers
as a metaphor for the inner conflicts experienced by a teenager in trying to become an
adult. In psychological work with adolescents, there is a stark similarity between what
they experience and some concepts of existentialist philosophy. Sartre’s script for the
movie Les Jeux Sont Faits (literally ‘‘games are made’’) uses the same narrative strategy
as Life is Strange—the capacity for the main characters to travel back in time to change
their own existence—in order to stimulate philosophical, ethical, and political thinking
and also to effectively simulate existential ‘‘limit situations.’’ This article is a dialogue
between Sartre’s views and Life is Strange in order to examine to what extent questions
such as what is freedom? what is choice? what is autonomy and responsibility?
can be interpreted anew in hybrid digital–human—‘‘anthrobotic’’—environments
On the Concept of Creal: The Politico-Ethical Horizon of a Creative Absolute
Process philosophies tend to emphasise the value of continuous creation as the
core of their discourse. For Bergson, Whitehead, Deleuze, and others the real is
ultimately a creative becoming. Critics have argued that there is an irreducible
element of (almost religious) belief in this re-evaluation of immanent creation.
While I don’t think belief is necessarily a sign of philosophical and existential
weakness, in this paper I will examine the possibility for the concept of universal
creation to be a political and ethical axiom, the result of a global social
contract rather than of a new spirituality. I argue here that a coherent way to
fight against potentially totalitarian absolutes is to replace them with a virtual
absolute that cannot territorialise without deterritorialising at the same time:

CFD applications: The Lockheed perspective
The Numerical Aerodynamic Simulator (NAS) epitomizes the coming of age of supercomputing and opens exciting horizons in the world of numerical simulation. An overview of supercomputing at Lockheed Corporation in the area of Computational Fluid Dynamics (CFD) is presented. This overview will focus on developments and applications of CFD as an aircraft design tool and will attempt to present an assessment, withing this context, of the state-of-the-art in CFD methodology
Transonics and fighter aircraft: Challenges and opportunities for CFD
The application of computational fluid dynamics (CFD) to fighter aircraft design and development is discussed. Methodology requirements for the aerodynamic design of fighter aircraft are briefly reviewed. The state-of-the-art of computational methods for transonic flows in the light of these requirements is assessed and the techniques found most adequate for the subject application are identified. Highlights from some proof-of-feasibility Euler and Navier-Stokes computations about a complete fighter aircraft configuration are presented. Finally, critical issues and opportunities for design application of CFD are discussed
Some possible sources of IceCube TeV-PeV neutrino events
The IceCube Collaboration has observed 37 neutrino events in the energy range
PeV and the sources of these neutrinos are
unknown. Here we have shown that positions of 12 high energy blazars and the
position of the FR-I galaxy Centaurus A, coincide within the error circles of
ten IceCube events, the later being in the error circle of the highest energy
event so far observed by IceCube. Two of the above blazars are simultaneously
within the error circles of the Telescope Array hotspot and one IceCube event.
We found that the blazar H2356-309 is within the error circles of three IceCube
events. We propose that photohadronic interaction of the Fermi accelerated high
energy protons with the synchrotron/SSC background photons in the nuclear
region of these high energy blazars and AGN are probably responsible for some
of the observed IceCube events.Comment: 14 pages, 3 figure, references adde
Risk and Efficiency in Credit Concession: A Case Study in Portugal
The relationship between banks and customers has contributed to several theories in banking economics. The quality of the credit is crucial for banks. Banks classify the risk through quantitative and qualitative indicators. Quantitative indicators are much used by banks, but qualitative indicators are also considered in credit risk evaluation. Taken together, they contribute to increase efficiency and decrease doubtful credit. Several issues arise in order to understand if risk evaluation affects the efficiency of the banking sector or if it affects the bank customer relationship. We wish to analyse some quantitative and qualitative indicators used by the Portuguese banking system. Despite the reputation of a client being a very important qualitative indicator, it is not enough to determine a classification of low risk.credit, banks, bankruptcy, risk
Multi-TeV flaring from blazars: Markarian 421 a case study
The TeV blazar Markarian 421 underwent multi-TeV flaring during April 2004
and simultaneously observed in x-ray and TeV energies. It was observed that the
TeV outbursts had no counterparts in the lower energies, which implies that
this might be an orphan flare. In the context of hadronic model, we have shown
that this multi-TeV flaring can be produced due to the interaction of
Fermi-accelerated protons of energy TeV with the background
photons in the low energy tail of the synchrotron self-Compton spectrum of the
blazar jet. We fit very well the flaring spectrum with this model. Based on
this study, we speculate that Mrk 501 and PG 1553+113 are possible candidates
for orphan flaring in the future.Comment: 8 pages, two columns, 3 figure
Photohadronic scenario in interpreting the February-March 2014 flare of 1ES 1011+496
The extraordinary multi-TeV flare from 1ES 1011 +496 during February-March
2014 was observed by MAGIC telescopes for 17 nights and the average spectrum of
the whole period has a non-trivial shape. We have used the photohadronic model
and a template EBL model to explain the average spectrum which fits well to the
flare data. The spectral index is the only free parameter in our
model. We have also shown that the non-trivial nature of the spectrum is due to
the change in the behavior of the optical depth above GeV
-ray energy accompanied with the high SSC flux.Comment: 11 pages, 3 figures, LaTe
