01. Inside the Idea Factory , Santa Fe New Mexican

Excerpts: The article traces the history of SFI from its 1984 beginnings
through today, with a
focus on new
scientific research directions and as well as our innovative Business
Network Program. (...)
Researchers say they have found striking similarities between the two
brands of virus, so having
the biological side of the sciences working with the computer side provides
data for both.

"Perhaps one of the big values is as a network," Bell said. "The people
they (SFI) attract and the
problems they go after are just very useful. I think when you bring that
collection of people
together, you really redirect. Everybody goes away thinking quite
differently about what they're
doing.

01.01. Analyzing The Analysts , Darwin Magazine

Excerpts: The
StarMine service, free on Yahoo, measures "analyst recommendation
performance."(...)

StarMine measures analyst recommendation performance on a 1-to-5 scale,
representing the return
performance of an analyst's recommendations relative to his or her peers.
To reach the scocres,
StarMine analyzes every recommendation, upgrade and downgrade published by
thousands of sell-side
analysts around the world. Analysts are measured in two ways: on an
absolute scale (used in the
industry rankings) and on a coverage-relative scale (used for an analyst's
overall score). Only
analysts scoring 4 or 5 stars are displayed.

02. The Origin Of Speech , Science

Excerpts: Archaeologists have identified various milestones in human
behavior in the 5-million-year
evolutionary void between animal communication and human speech, but there
is no consensus on which
achievements imply the capacity for language. For example, the first stone
tools date to 2.4
million years ago; some researchers think this may indicate linguistic
facility, but others argue
that toolmaking is far removed from speech. (...) 2 million years ago, when
the hominid brain began
a period of rapid expansion, including in the primary brain areas
associated with producing or
processing language (...).

02.01. Evolution of Language , Science

Excerpts: Complex language is clearly among the key traits that separate
humans from our ape
ancestors. A special section of the 27 Feb 2004 Science investigated how
this powerful ability to
communicate evolved and how language, (...), has changed over time. Five
News stories delved into
the history and prehistory of language evolution, from the origin of speech
to modern efforts to
organize the world's thousands of languages. Three Viewpoints explored the
rapid changes occurring
in our language systems as new technologies and international communication
strive to keep pace
with global population expansion.

02.02. The First Language? , Science

Excerpts: Genetic and linguistic data indicate--but can't quite prove--that
our ancient ancestors
spoke with strange clicking noises

(...) suggest that our early ancestors depended on such clicks to
communicate. The latest
linguistic work points to clicks as having deep roots, originating at the
limits of linguistic
analysis sometime earlier than 10,000 years ago, and genetic data suggest
that click-speaking
populations go back to a common ancestor perhaps 50,000 or more years ago.

(...) "population that was ancestral to all living humans lived in the
savanna and used clicks,"
(...).

02.03. Why Anatolia? , Science

Excerpts: (...) both the seeds of the Indo-European language and the
gateway for the spread of
agriculture into Europe some 8000 years ago. Recent research at a number of
Anatolian sites has
shown that this huge plateau was teeming with human populations, rich with
art and culture, and
home to the grains, cereals, and legumes key to the expansion of farming.
"Everybody agrees that
farming came to Europe from Anatolia," says (...) Colin Renfrew, chief
partisan of the
farming-dispersal model of Indo-European origins. "So Anatolia must be the
point of departure [for
languages too]."

02.04. Continuing The Debate On Words And Seeds , Science

Excerpts: What we find is not unexpected: the history of the world is more
complex than the
farming-language dispersal hypothesis suggests. Scratch the archaeology of
any one continent and
what had once been argued as a simple case of Neolithic dispersal becomes a
mosaic of multiple
processes that may have produced quite independent patterns of economic,
linguistic, and biological
change within the populations concerned.

Similarly, scratching the surface of any one discipline exposes
methodological difficulties. (...)
cultural change originates in the spread of people or of new ideas and
technologies.

02.05. The Future Of Language , Science

Excerpts: The world's language system is undergoing rapid change because of
demographic trends, new
technology, and international communication. (...) English may not be the
dominant language of the
future, and the need to be multilingual will be enhanced. Although many
languages are going
extinct, new ones are emerging in cities and extended social groups (...).
In the mid-20th century, nearly 9% of the global population grew up
speaking English as their first
language, but that proportion is declining oward nearer 5% by 2050.

02.06. Towards a New Functional Anatomy of Language , Cognition

Abstract: The classical brain-language model derived from the work of
Broca, Wernicke, Lichtheim,
Geschwind, and others has been useful as a heuristic model that stimulates
research and as a
clinical model that guides diagnosis. However, it is now uncontroversial
that the classical model
is (i) empirically wrong in that it cannot account for the range of aphasic
syndromes, (ii)
linguistically underspecified to an extent that prohibits contact with the
language sciences, and
(iii) anatomically underspecified. We briefly summarize some of the central
issues that motivate
why a new functional anatomy of language is necessary, in the context of
introducing a collection
of articles that describe systematic new attempts at specifying the new
functional anatomy. The
major convergent observations are highlighted and the emergent conceptual
and empirical trends are
identified.

03. Emergent Properties Of CNS Neuronal Networks As Targets For
Pharmacology , Progress in
Neurobiology

Abstract: CNS [Central Nervous System, Ed.] drugs may act by modifying the
emergent properties of
complex
CNS neuronal networks. Emergent properties are network characteristics that
are not predictably
based on properties of individual member neurons.
Neuronal membership within networks is controlled by several mechanisms,
including burst firing,
gap junctions, endogenous and exogenous neuroactive substances,
extracellular ions, temperature,
interneuron activity, astrocytic integration and external stimuli. The
effects of many CNS drugs in
vivo may critically involve actions on specific brain loci, but this
selectivity may be absent when
the same neurons are isolated from the network in vitro where emergent
properties are lost.

03.01. Cortical processing of complex sound: a way forward? , Trends in
Neurosciences

Abstract: The organization of the cortical auditory system remains
controversial. In
particular, the extent to which there is regional specialization in the
cortical
processing of complex sound is unclear. Here, we ask whether we are
currently asking the right questions of auditory cortex, or using the
appropriate
techniques to do so. A key factor that will promote such understanding in the
future will be increasing dialogue between workers using electrophysiological
recording methods to assess the response properties of single neurons and
those using imaging techniques to map regional organization. In the future,
further insights will be obtained by efforts to test hypotheses developed
on the
basis of one approach by the use of the other. Imaging can tell the
neurophysiologists where to look, and work on single neurons can constrain
network models based on imaging. There is a crucial need for better
understanding of the anatomy of the auditory cortex in different species
and for
comparative studies that will underpin both approaches.

03.02. Memories Light Up The Corners Of Our Minds , ScienceDaily

Excerpts: Memories do indeed light up the corners of our mind, just as the
songwriter said.
Scientific evidence for this notion comes from studies using magnetic
resonance imaging to examine
the living human brain. These studies show that certain brain areas "light
up" as an individual is
learning information. Scientists had previously established that people
remember emotionally
charged events and facts better than neutral ones. Now researchers at MIT
have discovered that
memories with an element of arousal or excitement are remembered by a
different area of the
brain-the amygdala-from memories of a calmer nature, which are remembered
by the prefrontal cortex

04. Understanding Environmental Complexity Through A Distributed Knowledge
Network , BioScience

Abstract: Understanding environmental complexity and other dimensions of
ecological systems
necessitates a holistic approach that can be achieved only by identifying,
retrieving, and
synthesizing diverse data from distributed sources; by collaborating with
other scientists from a
broad range of disciplines; and by investigating many different systems.
Knowledge Network for
Biocomplexity is developing new software tools to advance ecological
understanding through
discovery, access, retrieval, and management of distributed and
heterogeneous ecological and
environmental data. To address the need for cultural change in ecologists
and other environmental
scientists (...) training a cadre of young investigators (...) with
emphasis on multiscale
integration and synthesis.

04.01. Evolving a Stigmergic Self-Organized Data-Mining , arXiv

Abstract: Self-organizing complex systems typically are comprised of a
large number of frequently
similar components or events. Through their process, a pattern at the
global-level of a system
emerges solely from numerous interactions among the lower-level components
of the system. Moreover,
the rules specifying interactions among the system's components are
executed using only local
information, without reference to the global pattern, which, as in many
real-world problems is not
easily accessible or possible to be found. Stigmergy, a kind of indirect
communication and learning
by the environment found in social insects is a well know example of
self-organization, providing
not only vital clues in order to understand how the components can interact
to produce a complex
pattern, as can pinpoint simple biological non-linear rules and methods to
achieve improved
artificial intelligent adaptive categorization systems, critical for
Data-Mining. On the present
work it is our intention to show that a new type of Data-Mining can be
designed based on Stigmergic
paradigms, taking profit of several natural features of this phenomenon. By
hybridizing
bio-inspired Swarm Intelligence with Evolutionary Computation we seek for
an entire distributed,
adaptive, collective and cooperative self-organized Data-Mining. As a
real-world, real-time test
bed for our proposal, World-Wide-Web Mining will be used. Having that
purpose in mind, Web usage
Data was collected from the Monash University's Web site (Australia), with
over 7 million hits
every week. Results are compared to other recent systems, showing that the
system presented is by
far promising.

provide personalized product recommendations to their users have gained a
lot of interest in recent

09. The Complex Interaction Of Aerosols And Clouds , Science

Excerpts: Aerosols have an important effect on atmospheric chemistry
throughout the troposphere and
lower stratosphere. They influence the radiative budget of Earth directly
and indirectly by the
modification of the cloud droplet size spectrum and precipitation at the
surface. Researchers are
beginning to incorporate these effects into the most sophisticated climate
models for shallow
clouds. This is because aerosol-cloud interactions are seen as one of the
most important single
forces that drive climate change, but there are big uncertainties in the
current understanding of
these processes.

while waiting in a bus station or travelling on a train. Half of the
conversations were by mobile
phone, so that only one end of the conversation was heard, and half were co
present face-to-face
conversations. Analysis of variance showed that mobile phone conversations
were significantly more
noticeable and annoying than face-to-face conversations at the same volume
when the content of the
conversation is controlled. Indeed this effect of medium was as large as
the effect of loudness.
Various explanations of this effect are explored, (...).

11.01. Comparative Usability Evaluation , Behav. & Info. Tech.

Abstract: This paper reports on a study assessing the consistency of
usability testing across
organisations. Nine independent organisations evaluated the usability of
the same website,
Microsoft Hotmail. (...) no two teams reported the same problem. Some of
the unique findings were
classified as serious. Even the tasks used by most or all teams produced
very different results -
around 70% of the findings for each of these tasks were unique. Our main
conclusion is that our
simple assumption that we are all doing the same and getting the same
results in a usability test
is plainly wrong.

12. Long-Term Working Memory And Interrupting Messages In Human - Computer
Interaction , Behav. &
Info. Tech.

Abstract: The extent to which memory for information content is reliable,
trustworthy, and accurate
is crucial in the information age. Being forced to divert attention to
interrupting messages is
common, however, and can cause memory loss. The memory effects of
interrupting messages were
investigated in three experiments. In Experiment 1, attending to an
interrupting message decreased
memory accuracy. In Experiment 3, an interrupting message was shown to be
most disturbing when it
was semantically very close to the main message. (...) it is argued that
interrupting messages can
both disrupt the active semantic elaboration (...) and cause semantic
interference upon retrieval.

13. The Minority Game: An Introductory Guide , arXiv

Abstract: The Minority Game is a simple model for the collective behavior
of agents in an idealized
situation where they have to compete through adaptation for a finite
resource. This review
summarizes the statistical mechanics community efforts to clear up and
understand the behavior of
this model. Our emphasis is on trying to derive the underlying effective
equations which govern the
dynamics of the original Minority Game, and on making an interpretation of
the results from the
point of view of the statistical mechanics of disordered systems.

14. Tragedy Of The Commons In Melipona Bees , Alphagalileo & Biol. Lett.

Abstract: Inequality among social classes or castes is a frequent cause of
conflict in human
society. In social insects such as ants, bees and wasps, individuals can
develop as one of two
castes, queen or worker. (...) studied Melipona stingless bees native in
tropical America where
each individual bee can determine its own caste development. If each bee
chose its caste only for
the good of the colony, almost all should be workers. But this is not what
happens. Up to 15% were
selfish, developing as queens even if they carried out no work in the colony.

14.01. Patterns And Coevolutionary Consequences Of Repeated Brood
Parasitism , Alphagalileo & Biol.
Lett.

Abstract: While many parasitic cuckoos lay eggs mimicking host eggs, other
brood parasites,
including cowbirds, lay distinct eggs. Yet cowbird hosts do not typically
eject odd-looking eggs.
During our colourbanding studies of two species of cowbird hosts, many
females were parasitised
multiple times during their lifespan. We then examined mathematically the
role of such repeated
experience with parasitism in the evolution of egg-ejection by would-be
foster parents. Increasing
repeated parasitism delayed the evolution of rejection, especially in
species that paid higher
costs when raising cowbird chicks. These observations help us understand
the counterintuitive
patterns of non-rejection by vulnerable hosts of parasites.

Excerpts: Ceramic materials are generally thought to be much more brittle
than metals or
polymers. (...) ceramics can exhibit surprising flexibility. (...) can be
induced to grow by a
spontaneous self-coiling process and fuse to form a
single crystal ring tens of nanometers thick and several micrometers across.
(...) Compared to the macromolecular building blocks of living systems like

Excerpts: The best way to combat casual crime is not to search for
persistent offenders but to
deter people from committing their first crime.

(...) people who do and don't commit crimes appear to be governed by
slightly different statistical
rules. The two types live in different mathematical worlds, the researchers
say. A switch in
statistical behaviour occurs just once, when a young person crosses the
divide. Once having
committed a single crime, a youth is statistically likely to go on to
commit any number of further
crimes, (...).

Excerpts: Mathematical models incorporating ecological data are starting to

During Britain's epidemic of foot-and-mouth disease in 2001, the government
culled some 4 million
cattle, pigs and sheep. These drastic measures were introduced following
the advice of a new breed
of epidemiologist ?those who deploy mathematical models of disease ecology
to predict the progress
of an outbreak and the probable effectiveness of different control
strategies. In this case, the
modellers crunched data on the distribution of farms, the size of herds,
wind patterns and records
of recent animal transport.

off to an international
force under the United Nations. Planning for that force has barely begun,

Excerpts: If you want to decide which football team takes the ball first or
who gets the larger
piece of cake, the fairest thing is to toss a coin, right? Not necessarily.

A new mathematical analysis suggests that coin tossing is inherently
biased: A coin is more likely
to land on the same face it started out on. (...)

This slight bias pales when compared with that of spinning a coin on its
edge. A spinning penny
will land as tails about 80 percent of the time.

Before the Iowa caucuses kicked off the US presidential primary elections
on (...), most polling
organizations were predicting a virtual tie between the top (...)
candidates. (...)

What looked like a serious polling blunder was more likely due to a
last-minute surge of support
for Kerry, and the quirky rules of the Iowa caucuses, which allow voters to
switch their support
after the voting begins.

issues told me last month, ne thing we do know is that this was not a rogue
operation. Suppose
Edward Teller had suddenly decided to spread nuclear technology and
equipment around the world. Do
you really think he could do that without the government knowing? How do
you get missiles from
North Korea to Pakistan? Do you think A.Q. shipped all the centrifuges by
Federal Express? The
military has to be involved, at high levels.?

the main hub through which traffickers have routed their illegal commerce
to hide their trails. Yet
the United States, which has depended on the emirates as a pillar of

Middle East and, since 1991, as a host to American troops, has done little
to pressure it to crack
down on illicit arms trade.

19.02. German Judges Order A Retrial For 9/11 Figure , NY Times

Excerpts: Complaining that crucial evidence had been withheld by the German
and American
authorities, a five-judge panel threw out the year-old conviction of Mr.
Motassadeq and sent the
case back to the lower court in Hamburg, which had sentenced him to 15
years in prison on more than
3,000 counts of accessory to murder.

(...) was denied a fair trial because the United States refused to allow
testimony by Ramzi bin
al-Shibh, a suspect in American captivity who is believed to have played a
central role in the
Sept. 11 plot.
Editor's Note: This example seems to suggest that the fight against global
terrorist networks is
made less effective by weakening the global network of legal prosecution.

Sylvain Savolainen for The New York Times

making its cards a favorite with criminals. But investigators were able to
match
the numbers with terror suspects and track some down in Pakistan, Saudi
Arabia, Indonesia and several countries in Europe. Switzerland is ending
anonymous card sales on July 1.

Excerpts: Part of the reason so many are being held is that soldiers' work
is not police work. Tips
are not as reliable. Artillerymen are not detectives. The troops cast a
wide net and then sort
through the catch, with much of the investigation coming after the arrest,
not before. (...)

Under international law, the American authorities have the right as
occupiers to detain anyone who
poses a security threat, even without enough evidence to prosecute. But in
Iraq, unlike in postwar
Japan or Germany, occupation has come without pacification.
