The Shape Of The 21st Century Corporation, WEF
We know what the new corporation design will be.
Principles of complexity including biological metaphors,
feedback loops, emphasis on networks and temporary teams are
all part of the new construction. I have called it the Next
Economy.
But implementation is going to be critical and difficult.
It is true with most management theories in their early days
that general explanations are cheap but operations are dear.
And so it is in Davos where executives readily espouse
complexity principles for organization but are weak on how
to put them in place and how to keep them there once they
are installed.

Protests against WEF have been on the news but usually
there is little information about what the protests are about.
Noam Chomsky summarizes some of the problems of globalization:
Excerpt: After World War II, integration of the
international economy ("globalization") has been increasing. By
late 20th century, it had reversed the decline of the interwar
period, reaching the level prior to World War I by gross
measures - for example, volume of trade relative to the size of
the global economy. But the picture is considerably more
complex.
Postwar integration passed through two phases: (1) the
Bretton Woods period until the early 1970s; (2) the period
since, after the dismantling of the Bretton Woods system of
regulated exchange rates and controls on movement of capital.
It is phase (2) that is usually called "globalization." Phase
(2) is associated with so-called "neoliberal policies":
structural adjustment and "reform" along the lines of the
"Washington consensus" for much of the Third World, and since
1990, others, such as India and the "transition economies" of
Eastern Europe; and a version of the same policies in the more
advanced industrial societies themselves, most notably the US
and UK. The two phases have been strikingly different. For good
reasons, many economists refer to phase (1) as the "golden age"
of industrial state capitalism, and phase (2) - the
"globalization period" - as the "leaden age," with significant
deterioriation of standard macroeconomic measures worldwide
(rate of growth, productivity, capital investment, etc.), and
increasing inequality. In the world's richest country, for most
of the workforce wages have stagnated or declined, working
hours have dramatically increased, and benefits and support
systems have been reduced. Through the "golden age," social
indicators closely tracked GDP; since the mid-1970s, they have
steadily declined, to the level of 40 years ago according to
the most recent detailed academic study.
Contemporary globalization is described as expansion of
"free trade," but that is misleading. A large part of "trade"
is in fact centrally-managed, through intrafirm transfers,
outsourcing, and other means. Furthermore, there is a strong
tendency towards oligopoly and strategic alliances among firms
throughout the economy, along with extensive reliance on the
state sector to socialize risk and cost, a key feature of the
US economy throughout this period. The international "free
trade" agreements involve an intricate combination of
liberalization and protectionism, in many crucial cases
(particularly pharmaceuticals) allowing megacorporations to
gain huge profits by monopolistic pricing of drugs that were
developed with substantial contribution of the public sector.
The enormous explosion of short-term speculative capital
transfers in phase (2) sharply restricts planning options for
governments, hence restricts popular sovereignty insofar as the
political system is democratic. The constitution of "trade" is
far different from the pre-World War I period. A large part now
consists of manufacturing flows to the rich countries, much of
it intrafirm. These options, along with the mere threat to
transfer production, are another powerful weapon against
working people and functioning democracy. The emerging system
is one of "corporate mercantilism," with decisions over social,
economic, and political life increasingly in the hands of
unaccountable private concentrations of power, which are "the
tools and tyrants of government," in James Madison's memorable
phrase, warning of the threats to democracy he perceived two
centuries ago.
Not surprisingly, the phase (2) effects have led to
substantial protest and public opposition, which has taken many
forms throughout the world. The World Social Forum offers
opportunities of unparalleled importance to bring together
popular forces from many and varied constituencies from the
richer and poor countries alike, to develop constructive
alternatives that will defend the overwhelming majority of the
world's population from the attack on fundamental human rights,
and to move on to break down illegitimate power concentrations
and extend the domains of justice and freedom.

Methods from chaos theory have been applied to analyze
brain waves for a number of years. The idea to do the inverse
"control of chaos" to convert unwanted brainwave patterns like
those from epileptic seizures has also been applied but not to
real human brains. The problem is the vast complexity of brain
dynamics and its most characteristic feature that it learns.
Besides changing chaotic seizure patterns to periodic ones in
rat brains not much progress has been made. One can also be
skeptical about rat brain results by Gluckman et al. who treat
the brainwaves like noise that can be canceled out by a method
that is successfully applied to cancel out e.g. engine noise in
airplanes:
"We describe a novel method of adaptively controlling
epileptic seizure-like events in hippocampal brain slices using
electric fields. Extracellular neuronal activity is
continuously recorded during field application through
differential extracellular recording techniques, and the
applied electric field strength is continuously updated using a
computer-controlled proportional feedback algorithm. This
approach appears capable of sustained amelioration of seizure
events in this preparation when used with negative feedback.
Seizures can be induced or enhanced by using fields of opposite
polarity through positive feedback. In negative feedback mode,
such findings may offer a novel technology for seizure control.
In positive feedback mode, adaptively applied electric fields
may offer a more physiological means of neural modulation for
prosthetic purposes than previously possible. " (1)
Another problem is to find a good location for placing the
electrodes in the brain. This and other problems have been
solved a number of years ago by Niels Birbaumer and his group.
Instead of placing electrodes in the brain they take advantage
of the brain's capability to learn where to modify its
self-generated electrical fields to suppress epileptic
seizures:
Adaptive Electric Field Control of Epileptic Seizures, J. Neurosci.
"In two controlled studies epileptic
patients with secondary generalized seizures were treated with
biofeedback of slow cortical potentials. Most of these patients
suffered from temporal lobe epilepsy which is known to be
resistant to drug management. In 35 sessions subjects learned
to regulate their cortical potentials with the help of a
biofeedback device. They were also taught how to recognize the
first subjective signs of an upcoming seizure before the
cortical EEG showed pathological epileptic activity. At the end
of training subjects had to perform the self-regulation task in
a distracting, realistic environment and to perceive their own
cerebral negativity before it reached the threshold for the
seizure. During the 18-month follow-up more than one half of
the patients showed substantial improvement in terms of the
decrement of seizure frequency. "Booster" sessions six and
twelve months after the end of training demonstrated that the
acquired self-regulation skill was not forgotten, but remained
the same over the time. Patients who displayed large negative
slow waves in all conditions at the beginning of training, did
not improve their clinical status even if they were able to
influence their EEG. Thus a psycho-physiological examination at
the beginning of training can help to select patients who will
profit from this technique. These data constitute an impressive
confirmation that a medical disease can be substantially
improved by a behavioral strategy. Moreover, a
psycho-physiological examination at the beginning of training
can help to select patients who will profit from this
technique. This behavioral strategy must, therefore, be
tailored to the patho-physiological condition. " (2)

Excerpts: The researchers hope to test prototype
devices on human patients within a year, having shown that the
system can reduce the severity of simulated seizures in the brain
tissue of rats. (...)
"The device senses what the brain network is doing and sends
in an electrical field to disrupt the seizure event," says
neurosurgeon Steven Schiff, a member of the team. He compares the
implants to 'noise-cancellation' headphones, like those used by
pilots to cancel out unwanted noise by creating reverse-phase
'anti-noise'.

Control of Synapse Number by Glia, Science
Glia are brain cells often described as providing
"support" for the less numerous, but more famous, neuronal
brain cells. Now, Ullian et al. (p.
657; see the news story by Helmuth)
show that glia in culture control the number of synapses on
neurons and that they are necessary for the maintenance of
proper synaptic electrophysiological responses. In the newborn
rat, synapses are formed in the superior colliculus at the end
of the first week after birth, at precisely the same time that
atrocytic glia appear and proliferate. The authors suggest that
glia may trigger immature and highly plastic synapses in the
developing brain to increase and stabilize in order to lock
synaptic circuitry in place.
Abstract: Although astrocytes constitute nearly half
of the cells in our brain, their function is a long-standing
neurobiological mystery. Here we show by quantal analyses,
FM1-43 imaging, immunostaining, and electron microscopy that
few synapses form in the absence of glial cells and that the
few synapses that do form are functionally immature. Astrocytes
increase the number of mature, functional synapses on central
nervous system (CNS) neurons by sevenfold and are required for
synaptic maintenance in vitro. We also show that most synapses
are generated concurrently with the development of glia in
vivo. These data demonstrate a previously unknown function for
glia in inducing and stabilizing CNS synapses, show that CNS
synapse number can be profoundly regulated by nonneuronal
signals, and raise the possibility that glia may actively
participate in synaptic plasticity.
Glia Tell Neurons to Build Synapses, Science
Although glia account for 90% of the cells in the adult
human brain, they've been written off as simple scaffolding
that supports neurons, as sources of nutrition, or as a
waste-disposal mechanism for sopping up extra ions and
neurotransmitter molecules. But a new study on page
657
shows that glia play a more important role in neuron-to-neuron
communication: They tell neurons to start talking to one
another.
More than a Supporting Role, Science
The United Nations-sponsored Intergovernmental Panel on
Climate Change officially declared early this week that "most of
the observed warming over the last 50 years is likely to have been
due to the increase in greenhouse gas concentrations." The panel
was vaguer than ever, though, about how bad things could get by
the end of the century. At a minimum, the world will warm more
than twice as much in the coming century as it did in the past
one, the panel concluded, but it could warm 10 times as
much.
It's Official: Humans Are Behind Most of Global Warming, Science
Excerpt: Global warming is liable to become an even
more acute problem than anticipated, according to the new
assessment of the Intergovernmental Panel on Climate Change
(IPCC).
Whereas global average-surface temperature has increased by
0.6 °C during the past century, it is set to rise by between
1.4 °C and 5.8 °C by 2100, according to the report.
There is "new and stronger evidence" that global warming is caused
by human activities, it adds.
Assessment Ups The Ante On Climate Change, Nature
Excerpts: When 9000 geophysicists gathered here last
month for the annual fall meeting of the American Geophysical
Union, they heard the usual potpourri of earth and planetary
sciences, from A (for atmospheric sciences) to V (for
volcanology). Subjects included predicting eruptions and
earthquakes in Iceland, piggyback monitoring of atmospheric
electrical circuits, and odd annual pulsations of the solid
earth.(…)
Now, some suspect that Earth is also "breathing,"
compressing its crust and extending it once each year. This cycle
is most evident in Japan, geophysicists told the meeting, where it
may be responsible for that country's "earthquake season."
Elsewhere, it may lead some volcanoes to erupt almost solely
between September and December.
Earth's Breathing Lessons, Science
Abstract: Cultured human and rodent cells divide a set
number of times before they cease dividing, a process called
replicative senescence. But how do they know when to stop
dividing? It appears that human cells have a way to count the
number of divisions they have undergone: they monitor the
progressive shortening of the ends of their chromosomes with each
division. However, rodent cells do not appear to have any
intrinsic counting method. In their Perspective, Shay and Wright
now reveal that rodent cells, when grown under the correct culture
conditions, can divide continuously (Mathon et al., Tang et al.).
They propose that cells from long-lived humans and short-lived
rodents have adopted different methods to respond to the insults
that they accumulate through their lifetimes.
When Do Telomeres Matter?, Science
Abstract: Replicative senescence is thought to be an
intrinsic mechanism for limiting the proliferative lifespan of
normal somatic cells. We show here that rat Schwann cells can be
expanded indefinitely in culture, whilst maintaining checkpoints
normally lost during the immortalization process. These findings
demonstrate that senescence is not an inevitable consequence of
extended proliferation in culture.
Lack of Replicative Senescence in Normal Rodent Glia, Science
Abstract: Most mammalian somatic cells are thought to
have a limited proliferative capacity, as they permanently stop
dividing after a finite number of divisions in culture, a state
termed replicative cell senescence. Here we show that most
oligodendrocyte precursor cells purified from postnatal rat optic
nerve can proliferate indefinitely in serum-free culture if
prevented from differentiating; various cell-cycle inhibitory
proteins increase, but the cells do not stop dividing. The cells
maintain high telomerase activity and p53- and Rb-dependent
cell-cycle checkpoint response, and serum or genotoxic drugs
induce them to acquire a senescence-like phenotype. Our findings
suggest that some normal rodent precursor cells have an unlimited
proliferative capacity if cultured in conditions that avoid both
differentiation and the activation of checkpoint responses that
arrest the cell cycle.
Lack of Replicative Senescence in Cultured Rat Oligodendrocyte Precursor Cells, Science
Excerpts: Despite an apparent lack of determinants that
specify cell fate, spatial patterning of the mouse embryo is
evident early in development. (..). In many animal eggs, the sperm
entry position provides a cue for embryonic patterning, but until
now no such role has been found in mammals. Here we show that the
sperm entry position predicts the plane of initial cleavage of the
mouse egg. (…) We present a model for axial development that
accommodates these findings with the regulative nature of mouse
embryos.
Role For Sperm In Spatial Patterning Of The Early Mouse Embryo, Nature
- Abstract: The protein folding problem has attracted an
increasing attention from physicists. The problem has a flavor
of statistical mechanics, but possesses the most common feature
of most biological problems - the profound effects of
evolution. I will give an introduction to the problem, and then
focus on some recent work concerning the so-called
"designability principle". The designability of a structure is
measured by the number of sequences that have that structure as
their unique ground state. Structures differ drastically in
terms of their designability; highly designable structures
emerge with a number of associated sequences much larger than
the average. These highly designable structures (1) possess
"protein-like" secondary structures and motifs, (2) are
thermodynamically more stable, (3) fold faster than other
structures. These results suggest that protein structures are
selected in nature because they are readily designed and stable
against mutations, and that such selection simultaneously leads
to thermodynamic stability and foldability. According to this
picture, a key to the protein folding problem is to understand
the emergence and the properties of the highly desginable
structures.
Simple Models Of The Protein Folding Problem, Physica A
Abstract: We represent a protein's structure by its contact
map. Our aim is to identify the unknown fold of a known sequence
by minimizing a (free) energy de ned in the space of contact maps.
To this end, we developed an efficient method to search this space
and to generate low energy maps that are also physical. We proved
that the standard pairwise approximation to the free energy is
unable to stabilize the native fold of a single protein against a
set of carefully generated decoys.
Protein Folding In Contact Map Space, Physica A
Abstract: Traders in a market typically have widely
different, private information on the return of an asset. The
equilibrium price of the asset may reflect this information more
accurately if the number of traders is large enough compared to
the number of the states of the world that determine the return of
the asset. We study the transition from markets where prices do
not reflect the information accurately into markets where it does.
In competitive markets, this transition takes place suddenly, at a
critical value of the ratio between number of states and number of
traders. The Nash equilibrium market behaves quite differently
from a competitive market even in the limit of large economies.
Statistical Mechanics Of Asset Markets With Private Information, arXiv
Abstract: We extend the model of rational bubbles of
Blanchard and of Blanchard and Watson to arbitrary dimensions d: a
number d of market time series are made linearly interdependent
via d times d stochastic coupling coefficients. We first show that
the no-arbitrage condition imposes that the non-diagonal impacts
of any asset i on any other asset j different from i has to vanish
on average, i.e., must exhibit random alternative regimes of
reinforcement and contrarian feedbacks. In contrast, the diagonal
terms must be positive and equal on average to the inverse of the
discount factor. Applying the results of renewal theory for
products of random matrices to stochastic recurrence equations
(SRE), we extend the theorem of Lux and Sornette
(cond-mat/9910141) and demonstrate that the tails of the
unconditional distributions associated with such d-dimensional
bubble processes follow power laws (i.e., exhibit hyperbolic
decline), with the same asymptotic tail exponent mu<1 for all
assets. The distribution of price differences and of returns is
dominated by the same power-law over an extended range of large
returns. This small value mu<1 of the tail exponent has
far-reaching consequences in the non-existence of the means and
variances. Although power-law tails are a pervasive feature of
empirical data, the numerical value mu<1 is in disagreement
with the usual empirical estimates mu approximately equal to 3.
It, therefore, appears that generalizing the model of rational
bubbles to arbitrary dimensions does not allow us to reconcile the
model with these stylized facts of financial data. The
non-stationary growth rational bubble model seems at present the
only viable solution (see cond-mat/0010112).
Application Of Stochastic Regression Equations To Financial Speculation, arXiv
Abstract: We introduce the concept of efficiency of a
network, measuring how efficiently it exchanges information. Using
this simple measure, we give a new unifying definition of
small-world networks, as systems that are both globally and
locally efficient. This allows to give a clear physical meaning to
the concept of small-world, and also to perform a precise
quantitative analysis of the system. We analyze different neural
networks and man-made transportation systems: besides showing the
subtle quantitative differences we show that the underlying
general principle of their construction is in fact a small-world
principle of high efficiency.
Efficient Behavior of Small-World Networks, arXiv
Abstract: We define predictive information
Ipred (T) as the mutual information between the past
and the future of a time series. Three qualitatively different
behaviors are found in the limit of large observation times T:
Ipred(T) can remain finite, grow logarithmically, or
grow as a fractional power law. If the time series allows us to
learn a model with a finite number of parameters, then
Ipred(T) grows logarithmically with a coefficient that
counts the dimensionality of the model space. In contrast,
power--law growth is associated, for example, with the learning of
infinite parameter (or nonparametric) models such as continuous
functions with smoothness constraints. There are connections
between the predictive information and measures of complexity that
have been defined both in learning theory and in the analysis of
physical systems through statistical mechanics and dynamical
systems theory. Further, in the same way that entropy provides the
unique measure of available information consistent with some
simple and plausible conditions, we argue that the divergent part
of Ipred(T) provides the unique measure for the
complexity of dynamics underlying a time series. Finally, we
discuss how these ideas may be useful in different problems in
physics, statistics, and biology.

Abstract: The scope of mental development includes
cognitive, behavioral, emotional, and all other mental
capabilities that are exhibited by humans, higher animals, and
artificial systems. Computational principles of autonomous mental
development in humans and the synthesis of developmental programs
for robots and other artificial systems are beginning to be
actively studied. Robots that develop their mental skills
autonomously represent a fundamental change from the traditional
paradigm for constructing intelligent machines. Support for this
new field should lead to advances in science, engineering,
economy, and understanding of the mind.
Autonomous Mental Development By Robots And Animals, Science
It is time to start building machines which can learn and be
raised in the same way as humans, the authors of an article in the
journal Science say. Building an intelligent machine is no small
feat and so previous efforts have centred on designing a machine
to carry out specific tasks. (…)
"According to this paradigm, robots should be designed to go
through a long period of autonomous mental development, from
'infancy' to 'adulthood'.
Time For Real Intelligence?, BBC
Excerpt: They monitored the rats' brain activity while
they ran the maze, and then monitored what the brains did when the
animals slept. Like all mammals, including humans, rats go through
phases of rapid eye movement (REM) sleep, which in humans
correlates with dreaming.
The patterns were so similar that the researchers could tell
where on the maze the rats were in their dreams and how fast they
were dreaming they were running.
``We could identify what segment and what the pattern of the
running activity was during this REM sleep -- literally what they
were doing -- how they were running, where they were running,''
Wilson said.

Excerpt: Electromagnetically induced transparency is a
quantum interference effect that permits the propagation of light
through an otherwise opaque atomic medium (…) Here we use
electromagnetically induced transparency to bring laser pulses to
a complete stop in a magnetically trapped, cold cloud of sodium
atoms. Within the spatially localized pulse region, the atoms are
in a superposition state determined by the amplitudes and phases
of the coupling and probe laser fields.
Observation Of Coherent Optical Information Storage In An Atomic Medium Using Halted Light Pulses, Nature
Excerpt: Hau and her group then figured out a way to
make it work. Using sodium atoms and two laser beams, they made a
new kind of medium that entangles light and slows it down. The
laser beams glow yellow-orange like sodium streetlights, and the
cigar-shaped cloud of atoms is about eight-thousandths of an inch
long and about a third as wide.
Working with Chien Liu, a postdoctoral fellow at Rowland,
and Harvard graduate students Zachary Dutton and Cyrus Behroozi,
Hau kept tweaking the atoms until they completely stopped laser
light. This happens when a second laser beam directed at right
angles to the cloud of atoms is cut off. When that laser is
switched on again, it abruptly frees the light from the trap and
it goes on its way.
Hau explains that light entering the atomic entanglement
transfers its energy to the atoms. Light energy raises the atoms
to higher energy levels in ways that depend on the frequency and
intensity of the light. The laser illuminating the cloud at right
angles to the incoming beam acts like a parking brake, stopping
the beam inside the cloud when it is shut off. When it is turned
on again, the brake is released, the atoms transfer their energy
back to the light, and it leaves the end of the cloud at full
speed and intensity.
Hau's team stopped light for one-thousandth of a second.
Atomically speaking, "this is an amazingly long time," Hau notes.
"But we think it can be stopped for much longer."
