01. Effective Complexity , SFI Working Papers

Abstract: It would take a great many different concepts - or quantities -
to capture all of our
notions of what is meant by complexity (or its opposite, simplicity.)
However, the notion that
corresponds most closely to what we mean by complexity in ordinary
conversation and in most
scientific discourse is "effective complexity.?In nontechnical language, we
can define the
effective complexity (EC) of an entity as the length of a highly compressed
description of its
regularities [6,7,11].
  For a more technical definition, we need a formal approach both to the
notion of minimum
description length and to the distinction between regularities and those
features that are treated
as random or incidental.

01.01. External and Internal Complexity of Complex Adaptive Systems , SFI
Working Papers

Abstract: We introduce concepts of external and internal complexity to
analyze the relationship
between an adaptive system and its environment. We apply this theoretical
framework to the
construction of models in a cognitive system and the selection between
hypotheses through selective
observations performed on a data set in a recurrent process and propose a
corresponding neural
network architecture.

02. The Waterwheel in the Waterfall , arXiv

Abstract: A fundamental problem in evolutionary ecology research is to
explain how different
species coexist in natural ecosystems. This question is directly related
with species trophic
competition. However, competition theory, based on the classical logistic
Lotka-Volterra equations,
leads to erroneous conclusions about species coexistence. The reason for
this is incorrectly
interpreted interspecific interactions, expressed in the form of the
competition coefficients. Here
I use the logistic Lotka-Volterra type competition equations derived from
the so called resource
competition models to obtain the necessary conditions for species
coexistence. These models show
that only species with identical competitive abilities may coexist. Due to
such relations between
competing species ecosystems biodiversity decreases in the course of evolution.

03. Complex Systems In Language Evolution: The Cultural Emergence , Adv. in
Complex Sys.

Abstract: Language arises from the interaction of three complex adaptive
systems - biological
evolution, learning, and culture. We focus here on cultural evolution, and
present an Iterated
Learning Model of the emergence of compositionality, a fundamental
structural property of language.
Our main result is to show that the poverty of the stimulus available to
language learners leads to
a pressure for linguistic structure. When there is a bottleneck on cultural
transmission, only a
language which is generalizable from sparse input data is stable. Language
itself evolves on a
cultural time-scale, and compositionality is language's adaptation to
stimulus poverty.

special case of the
mechanisms that build the rest of our body. (...)

His goal is twofold: (a) "to track closely the progress in genetics, and
try to think about the
question of how a tiny number of genes can lead you from an ancestral
chimpanzee view of the world
to a human view of the world"; and (b) "to rethink linguistics as a

04. Decision Spread In The Corporate Board Network , Adv. in Complex Sys.

Abstract: The boards of large corporations sharing some of their directors
are connected in complex
networks. Boards are responsible for corporations' long-term strategy and
are often involved in
decisions about a common topic related to the belief in economical growth
or recession. We are
interested in understanding under which conditions a large majority of
boards making the same
decision can emerge in the network. We present a model (...) to explain the
fact that boards of the
largest corporations of a country can, in the span of a few months, make
the same decisions about
general topics.

Excerpts: Teachers shouldn't just assume a child is not paying attention if
they are seen "staring
into the distance" when asked a question. (...) adults can switch off from
stimulation (both live faces and other sorts of visual displays) in order
to concentrate better, a
technique called gaze aversion. When remembering information, thinking of
an answer to a question,
planning what we are going to say or speaking, we often close our eyes
(...) especially when the
task in hand is difficult. However, the new research has found that
children also use gaze aversion
to help them concentrate on difficult material.

06. Rare Ant May Help Solve Some Mysteries Of Social Evolution , ScienceDaily

Excerpts: L. minutissimus is a unique social parasite in that it lives
entirely within the colonies
of other ant species. But unlike parasitic slave-maker ants, which raid and
virtually destroy the
colonies of unsuspecting hosts, L. minutissimus appears to move in and live
amiably with its host.
(...) it doesn't appear to stage the bloodthirsty coups common to its
slave-maker ant relatives.
Rather, it behaves much like the unwelcome in-laws who come to visit for an
undetermined length of
time. Slave-makers therefore rely on overt aggression to make a living, but
L. minutissimus is
apparently accepted into host colonies without any violence.

07. Economic Development By The Creation Of New Sectors , J. Evol. Econ.

Abstract: (...) first entrepreneur entering a market enjoys a temporary
monopoly. This temporary
monopoly is eroded by the entry of imitators, that gradually increases the
intensity of
competition. The saturation is reinforced as the demand for what was a new
product comes to be
satisfied. In this way the adjustment gap initially created by the
innovation is eliminated
transforming a niche into a mature market, which becomes one of the
routines of the economic
system. (...) economic development is a process in which new activities
emerge, old ones disappear,
the weight of all economic activities and their patterns of interaction change.

internal characteristics. We
argue that they need to revisit the (...). Some associate information with
data, and others
associate information with knowledge. But since none of them readily
conflates data with knowledge,

information provide us with useful insights with which to build an

10. Agent Models And Different User Ontologies For An Electronic Market
Place , Knowl. & Info. Sys.

Abstract: In this paper the agent-based electronic market architecture GEMS
is described. The
market incorporates different user perspectives: consumers, retailers, and
producers. Ontologies
for the different user perspectives are included. Knowledge is included to
relate information from
the different perspectives; for example, evaluation knowledge that can be
used to derive product
evaluations in terms of user ontology from product information based on
producer ontology. Agent
models are used as a high-level design structure for the architecture. It
is shown how this
combination of agent models, ontologies and knowledge provides an adequate
approach to the
distributed and knowledge-intensive character of the application.

11. The Role Of Increasing Temperature Variability In European Summer
Heatwaves , Nature

Excerpts: We find that an event like that of summer 2003 is statistically
extremely unlikely, even
when the observed warming is taken into account. We propose that a regime
with an increased
variability of temperatures (in addition to increases in mean temperature)
may be able to account
for summer 2003. To test this proposal, we simulate possible future
European climate with a
regional climate model in a scenario with increased atmospheric
greenhouse-gas concentrations, and
find that temperature variability increases by up to 100%, with maximum
changes in central and
eastern Europe.

New Yorkers may be able to blame the city's current cold spell ?the most
severe in nearly a decade
?on global warming.

Global warming doesn't mean that every place on the globe gets warmer. The
weather history that can
be read in polar ice-core samples indicates that previous periods of
warming affected North America
and Europe far differently than they did the tropics ?the Northern
Hemisphere got a lot colder.

11.02. Nitric Acid Increases Relative Humidity in Low-Temperature Cirrus
Clouds , Science

Excerpts: In situ measurements of the relative humidity with respect to ice
(RHi) and of nitric
acid (HNO3) were made in both natural and contrail cirrus clouds in the
upper troposphere. (...) We
propose that surface HNO3 molecules prevent the ice/vapor system from
reaching equilibrium by a
mechanism similar to that of freezing point depression by antifreeze
proteins. {Delta}-ice
represents a new link between global climate and natural and anthropogenic
nitrogen oxide
emissions. Including {Delta} -ice in climate models will alter simulated
cirrus properties and the
distribution of upper tropospheric water vapor.
Editor's Note: We know that clouds are extremely sensitive parameters for
climate change dynamics.
The role of nitric acid as a cloud "anti freeze?could possible create a
significant shift in that
parameter with unforeseen consequences.

A reprise of waking neural activity during slow-wave sleep-the longest
sleep stage in rats and
people-promotes recall of novel experiences, the scientists propose. Then,
neural changes crucial
for memory storage occur during rapid eye movement (REM) sleep, in their view.
