01. Trade Liberalization, Corruption, And Environmental Policy Formation:
Theory And Evidence , J.
Env. Econ. & Management

Abstract: This study explores the linkages between trade policy,
corruption, and environmental
policy. We begin by presenting a theoretical model that produces several
testable predictions,
including: (i) the effect of trade liberalization on the stringency of
environmental policy depends
on the level of corruption; and (ii) corruption reduces environmental
policy stringency. Using
panel data from a mix of developed and developing countries from 1982 to
1992, we find evidence
that supports these conjectures. We view these results as representing an
attempt at understanding
the myriad of complex relationships that exist in an open economy.

01.01. Viscous Demand , J. Econ. Theory

Abstract: In many markets, demand adjusts slowly to changes in prices,
i.e., demand is "viscous".
This viscosity gives each firm some monopoly power, since it can raise its
price above that of its
competitors without immediately losing all of its customers. The resulting
equilibrium pricing
behavior and market outcomes can differ significantly from what one would
predict in the absence of
demand viscosity. In particular, the model explains the importance of
market share as an
investment, as well as "kinked demand curves". It also explains how
apparently "competitive"
pricing behavior can lead to outcomes that mimic those of collusion.

03. Pattern Excitation-Based Processing: The Music of The Brain , arXiv

Abstract: An approach to information processing based on the excitation of
patterns of activity by
non-linear active resonators in response to their input patterns is
proposed. Arguments are
presented to show that any computation performed by a conventional Turing
machine-based computer,
called T-machine in this paper, could also be performed by the pattern
excitation-based machine,
which will be called P-machine. A realization of this processing scheme by
neural networks is
discussed. In this realization, the role of the resonators is played by
neural pattern excitation
networks, which are the neural circuits capable of exciting different
spatio-temporal patterns of
activity in response to different inputs. Learning in the neural pattern
excitation networks is
also considered. It is shown that there is a duality between pattern
excitation and pattern
recognition neural networks, which allows to create new pattern excitation
modes corresponding to
recognizable input patterns, based on Hebbian learning rules.
Hierarchically organized, such
networks can produce complex behavior. Animal behavior, human language and
thought are treated as
examples produced by such networks.
Contributing Editor's Note: This paper shows that theoretical "brain like"
machines can perform the
same computations than a Turing machine. Could a Turing machine perform all
the computations a
"brain-like" machine can do? If so, can this be achieved only in theory, or
also in practice?

03.01. Neural Correlates of the Complexity of Rhythmic Finger Tapping ,

Abstract: Using functional magnetic resonance imaging (fMRI), we studied
the neural correlates of
the complexity of rhythmic finger tapping. Our experiments measured the
brain activity of 13
subjects performing rhythmic tapping on a response box with multistable
rhythms of 1 to 5 different
interresponse intervals. From the button press response times, we
constructed phase portraits where
we identified the number of clusters of periodic points in a rhythm that
corresponded to the number
of different beats of the rhythm performed. We then constructed a
statistical model for correlation
analysis involving the following behavioral parameters: rate of tapping and
number of beats in a
rhythm. The tapping rate correlated with the brain activity in the
ipsilateral pre/postcentral
gyrus, and the number of beats (complexity) was correlated with activations
in the primary motor
cortex, supplementary motor area, basal ganglia, thalamus, and cerebellum.
A region of interest
(ROI) average analysis showed that the complexity of a rhythm had a
differential correlation with
the activity in these regions. The cerebellum and the thalamus showed
increasing activity, and the
basal ganglia showed decreasing activity with complexity of a rhythm. These
results identify the
areas involved in a rhythm generation and the modulation of brain activity
with the complexity.

Summary: Semiconductor quantum dots (QDs) have recently emerged as probes
with the potential to
revolutionize fluorescence imaging. Dahan et al. (A HREF="

) have now detected single QD-tagged glycine receptors in living cultured
spinal neurons. By
combining in vivo monitoring and post hoc electron microscopic analysis,
the dynamics of receptors
was monitored over time and the entry of a receptor into the synapse was
directly observed.

06. Hierarchical Organization In Complex Networks , Phys. Rev. E

Abstract: Many real networks in nature and society share two generic
properties: they are
scale-free and they display a high degree of clustering. We show that these
two features are the
consequence of a hierarchical organization, implying that small groups of
nodes organize in a
hierarchical manner into increasingly large groups, while maintaining a
scale-free topology. We
find that several real networks, such as the World wide web, actor network,
the Internet at the
domain level, and the semantic web obey this scaling law, indicating that
hierarchy is a
fundamental characteristic of many complex systems. #level

06.01. How to Search a Social Network , arXiv

Abstract: We address the question of how participants in a small world
experiment are able to find
short paths in a social network using only local information about their
immediate contacts. We
simulate such experiments on a network of actual email contacts within an
organization as well as
on a student social networking website. On the e-mail network we find that
small world search
strategies using a contact's position in physical space or in an
organizational hierarchy relative
to the target can effectively be used to locate most individuals. However,
we find that in the
online student network, where the data is incomplete and hierarchical
structures are not well
defined, local search strategies are less effective. We compare our
findings to recent theoretical
hypotheses about underlying social structure that would enable these simple
search strategies to
succeed and discuss the implications to social software design.

07. Analysis of Norms Game in networked societies , arXiv

Abstract: Norms, defined as generally accepted behaviour in societies
without central authority
(and thus distinguished from laws), are very powerful mechanism leading to
coherent behaviour of
the society members. This paper examines, within a simple numerical
simulation, the various effects
that may lead to norm formation and stability. The approach has been first
used by Axelrod, who
proposed two step model of norm and meta-norm enforcement. We present here
an extension and
detailed analysis of the original work, as well as several new ideas that
may bear on the norm
establishment mechanisms in societies. It turns out that a relatively
simple model for simulated
norm enforcement predicts persistent norm breaking even when it is
associated with high punishment
levels. The key factors appear to be the combination of the level of
penalty for breaking the norm
and proximity of norm enforcers. We also study a totally different
mechanism of norm establishment,
without meta-norms but using instead the direct bonus mechanism to

century. He started from an intuitive statement about functional
complexity: 'An object is of the
highest degree of complexity if it can do very difficult and involved
things'. He nevertheless

a network of thousands
of chemical reactions (...). All the structural and functional patterns are
not determined in a

09.01. Does Tumor Growth Follow A "Universal Law"? , J. Theor. Biol.

Abstract: A general model for the ontogenetic growth of living organisms
has been recently
proposed. Here we investigate the extension of this model to the growth of
solid malignant tumors.
A variety of in vitro and in vivo data are analysed and compared with the
prediction of a
"universal" law, relating properly rescaled tumor masses and tumor growth
times. The results
support the notion that tumor growth follows such a universal law. Several
important implications
of this finding are discussed, including its relevance for tumor metastasis
and recurrence, cell
turnover rates, angiogenesis and invasion.

genital mismatch. Here we (? demonstrate the parallel evolution of reversal
between left and right
lineages of the Japanese land snail Euhadra. We find that the different
mirror-image forms have
evolved in favour of the genetically dominant handedness as a result of
single-gene speciation.

around 17 gigapascals,
half of the weak bonds between the graphite layers convert to diamondlike
