Tech. & Deci. Making

Excerpts: This paper shows that underlying parameters of perceived complexity
in the development of a technical platform in the mobile telecommunications
industry can be presented in a model consisting of four parameters, divided
into three levels. The parameters refer to the number of interrelated parts,
type of dependency among these parts, uncertainty in goals, and uncertainty in
methods. These complexity parameters can further be found on different levels -
external organization, internal organization, and product. The study also shows
that these underlying parameters come into play differently in different
settings, e.g. how these parameters are perceived is highly dependent on the
specific situation. (...)

pattern. (...) the paper estimates the direct and the indirect effect of
corruption on pollution. The indirect effect via income is positive or negative
depending on the income level. If negative, the indirect effect is dominated by
the positive direct effect. Overall, our measures of pollution are
monotonically increasing in corruption. Because this relationship is
particularly strong at low income levels, developing countries can considerably
improve both their economic and environmental performance by reducing

02. Modelling Strategies For Controlling SARS Outbreaks , Alphagalileo & Proc.

Excerpt: A new study by Canadian researchers shows that rapid isolation of
people with symptoms of SARS under strict hygiene is sufficient to contain the
disease, without requiring the quarantine of those without symptoms. By
analyzing 2003 outbreaks in Toronto, Hong-Kong, Singapore and Beijing, the
researchers found that once an outbreak is underway, screening for infected
people at ports of entry yields little benefit, and now requires quarantine of
those without symptoms (but feared exposed to the virus) to control the
outbreak. Investment of public health resources to develop rapid and adequate
isolation programs is crucial to efficiently control future outbreaks (...).

03.01. Pleiotropy As A Mechanism To Stabilize Cooperation , Nature

Excerpt: Most genes affect many traits. This phenomenon, known as pleiotropy,
is a major constraint on evolution because adaptive change in one trait may be
prevented because it would compromise other traits affected by the same genes.
Here we show that pleiotropy can have an unexpected effect and benefit one of
the most enigmatic of adaptations-cooperation. A spectacular act of cooperation
occurs in the social amoeba Dictyostelium discoideum, in which some cells die
to form a stalk that holds the other cells aloft as reproductive spores.

Excerpt: Synchronous arrival of pairs of migratory birds at their breeding
grounds is important for maintaining pair bonds (...). Here we show that
arrival is also synchronized in paired individuals of a migratory shorebird,
the black-tailed godwit (Limosa limosa islandica), even though they winter
hundreds of kilometres apart and do not migrate together. The mechanisms
required to achieve this synchrony and prevent 'divorce' illustrate the
complexity of migratory systems.

Breeding godwits arrived over a one-month period (...). Previously paired males
and females arrived within 3.1 (...) days of one another

Evolution , Science

Excerpt: Almost a third of insect pest populations worldwide are naturally
controlled by parasitoid wasps. One of the most astonishing strategies used by
some of these wasps to modulate the prey caterpillars' physiology is the
injection of a "symbiotic" polydnavirus along with the wasp's eggs. (...). The
viruses are not transmitted by infection, but are "inherited" as an endogenous
provirus integrated in the wasp's genome. The virus genome seems to have
evolved in partnership with the wasp's to play the role of a natural biological
insecticide, to both partners' ultimate benefit.

emerging technologies. (...)

He and Grossman recommend simple starches and foods low in sugar and high in
anti-inflammatory agents such as fish and nuts. They advise taking all sorts of

Proteins from embryonic stem cells saved embryos that would otherwise have died
from a heart defect.


The cells must have pumped some kind of heart-repairing substance into the
mother's bloodstream, which travelled across the placenta into the babies and
directed their heart cells to grow normally.


The team showed that both of these molecules together have the potential to
entirely reverse the growing animal's heart problem. They injected just 15
healthy embryonic stem cells, which were making both IGF-1 and WNT5a, into
mutant embryos. The babies that developed from the embryos were close to

Gas belched out from prehistoric volcanoes could have helped the first life to

The evolutionary history of head lice is tied very closely to that of their

Some head lice infesting people today were probably spread to us thousands of
years ago by an extinct species of early human, a genetics study reveals.

It shows that when our ancestors left Africa after 100,000 years ago, they made
direct contact with tribes of "archaic" peoples, probably in Asia.

One explanation is that the human population was reduced in size before it
expanded again after 100,000 years ago, as small bands of hunters left Africa.
As human populations mushroomed, so did those of head lice that lived on them.

Excerpt: Modern humans-Homo sapiens-are generally thought to have passed

by unravelling their evolutionary history it's possible to see past the
bottleneck, according to the Florida Museum of Natural History's David Reed,
lead author of the paper.

history is similar to having multiple camera angles recording an event," (...).

Excerpt: Space used by animals increases with increasing body size. Energy
requirements alone can explain how population density decreases, but not the
steep rate at which home range area increases. We present a general mechanistic
model that predicts the frequency of interaction, spatial overlap, and loss of
resources to neighbors. Extensive empirical evidence supports the model,
demonstrating that spatial constraints on defense cause exclusivity of home
range use to decrease with increasing body size. In large mammals, over 90% of
available resources may be lost to neighbors. Our model offers a general
framework to understand animal space use and sociality.

Abstract: Simple memorizing tasks have been chosen such as a binary code on a
matrix. After the establishment of an appropriate protocol, the codified
matrices were individually presented to 150 university students who had to
memorize them. A computer simulation for a similar task is available which uses
a perceptron on which an algorithm was implemented allowing for some degree of
globality (technically referred to as entropic nonextensivity within a current
generalization of the usual, Boltzmann-Gibbs, statistical mechanics). Our main
observation is that, for the very specific learning task on which we focus

Researchers have learned how to commandeer the complex machinery that cells use
to recognize and respond to such important molecules as steroid hormones,
thyroid hormones and vitamin D.

The development could provide a foundation for a new family of
biologically-based mechanisms able to detect common drugs, chemical weapons and
other small molecules. By allowing manipulation of this cellular protein
machinery ?known as nuclear receptors ?the technique could also lead to new
methods for producing enzymes and important pharmaceutical compounds.

14. Visionaries Outline Web's Future , BBC News

Excerpt: Universal access to all human knowledge could be had for around $260m,
a conference about the web's future has been told.

The idea of access for all was put forward by visionary Brewster Kahle, who
suggested starting by digitally scanning all 26 million books in the US Library
of Congress. (...)

Experts at the event said the next generation of the web will come out of the
creative and programming communities starting to tinker with the vast pool of
data the net has become.

14.01. Dynamical Networks for Information Processing , Information Sciences

Abstract: Coupled evolution of state and topology of dynamical networks is
introduced. Due to a well organized tensor structure, the governing equations
are presented in a canonical form, and required attractors as well as their
basins can be easily placed and controlled. This new class of dynamical
networks can represent phenomenological models for self-organization in physics
and biology. Applications of these networks to pattern recognition, associative
memory, synthesis of models based upon observation data, detection of
abnormalities and data compression are discussed. The difference between the
proposed dynamical networks and neural networks is emphasized.

15. The Active Site in Nanoparticle Gold Catalysis , Science

Excerpt: Most pollution from U.S. automobiles is emitted in the first 5 min
after startup. This is because Pt- or Pd-based catalysts currently used in
automobile exhaust cleanup are inactive below about 200ºC. (...) Gold
nanoparticles (...) have been shown to be amazingly active and selective as
catalysts (...). There is intense interest in these catalysts for carbon
monoxide oxidation, because they are active at room temperature. Interestingly,
the low-temperature gold catalysts are totally inactive unless the gold is in
the form of particles smaller than ~8 nm in diameter.

16. Pit Stop on the Cocaine Highway , Washington Post

Excerpts: Guatemala Becomes Favored Link for U.S.-Bound Drugs
He said that if Guatemalan anti-drug police happen to spot a drug plane now,
they have to ask the army for a helicopter to chase it. There is only one army
helicopter available to the police, (...).

Florido said it has been nearly impossible to catch the traffickers, who unload
their cocaine in minutes and then burn or abandon their planes. He said
traffickers with sophisticated boats also usually outrun Guatemalan naval
forces, which have limited navigation and communications equipment.

17. Ignorance Isn't Strength , NY Times

Excerpt: President Bush and Vice President Dick Cheney have an unparalleled
ability to insulate themselves from inconvenient facts. They lead a party that
controls all three branches of government, and face news media that in some
cases are partisan supporters, and in other cases are reluctant to state
plainly that officials aren't telling the truth. They also still enjoy the
residue of the faith placed in them after 9/11.

This has allowed them to engage in what Orwell called "reality control."

* Ignorance Isn't Strength, Paul Krugman  , 04/10/08, NYTimes


17.01. Campaign Security Screening Crowds for Doubters , NPR ME

Excerpt: Some would-be attendees at President Bush's campaign events say
they're being asked to leave for wearing clothes or stickers that support the
president's opponent. At Sen. Kerry's rallies, the presidential hopeful
ruefully acknowledges the presence of the opposition. NPR's Nina Totenberg
examines the rights of campaign event planners and attendees.

17.02. Bush's Isolation From Reporters Could Be a Hindrance , Washington Post

Excerpt: "If you don't talk to the press and deal with audiences with some
degree of skepticism, you can't build understanding so people have confidence
in you in hard times," Fields said. "His handlers think they're doing him a
favor, but they're not." (...).

The tradition of the White House news corps shouting questions at the president
has largely faded during this term because Bush reacts testily and does not
answer, and his staff typically sets up events so he does not have to walk near

18. The Battle of the Pump , NY Times

Excerpts: If we had imposed a new gasoline tax after 9/11, demand would have
been dampened and gas today would probably still be $2 a gallon. But instead of
the extra dollar going to Saudi Arabia - where it ends up with mullahs who
build madrasas that preach intolerance - that dollar would have gone to our own
Treasury to pay down our own deficit and finance our own schools. In fact, the
Bush energy policy should be called No Mullah Left Behind.
Editor's Note: Problems related to oil supplies seem to emerge as a global
pattern of conflict.
The impact of a focus on hydrogen technology in combination with a lack of
support of energy conservation measures also appears to contribute to this

18.01. Nigeria Fuel Price Strike Starts , BBC News

Excerpt: Many Nigerian shops and offices are closed at the start of a four-day
general strike over fuel price rises in Africa's largest oil producer.

The strike call has been followed in the main cities of Abuja and Lagos but oil
production has not been affected.

The strike is one reason why world oil prices have reached a new record high.
On Monday morning, prices of Brent crude oil passed the $50 a barrel mark for
the first time.

18.02. Venezuela Raises Oil Drilling Tax , BBC News

Excerpt: Venezuela has announced that it is increasing the royalties paid by
foreign oil companies from 1% to 16.6%.

President Hugo Chavez said it marked the second and true phase of the
nationalisation of the country's oil. (...)

The surprise measure will affect all foreign companies offering joint ventures
in Venezuela's Orinoco heavy crude belt.

During his address on Sunday, Mr Chavez said: "We are no longer going to give
our oil away for reasons that no longer exist, if they ever did."

18.03. Hydrogen Economy Looks Out Of Reach , Nature News

Excerpt: US vehicles would require a million wind turbines, economists claim.
"Today, hydrogen is not a clean, green fuel," says Oswald's brother Jim, an
energy consultant who assisted with the calculation. "You've got to ask: where
did the hydrogen come from?"

The only technology that can currently make large amounts of hydrogen without
using fossil fuels relies on renewable power sources or nuclear energy, the
Oswalds argue. Hydrogen will only mitigate global warming when a clean source
of the gas becomes available, they say.

19. Complex Challenges: Global Terroist Networks


19.01. Mathematicians Offer Help in Terror Fight , China Daily/AP

Excerpt: A small group of thinking men and women convened at Rutgers University
last month to consider how order theory ?a branch of abstract mathematics that
deals with hierarchical relationships ?could be applied to the war on

Theoretically, Farley said, abstract math could help intelligence officers
figure out the most efficient way to disable a terrorist network.

Say it's cheaper or more practical to go after a terrorist cell's "middle
management" rather than its leadership. How many of those lieutenants would you
have to remove in order to disrupt communication (...).

19.02. A Web Wise Terror Network , BBC

Excerpt: Communications have always been an essential part of al-Qaeda's
strategy, but the internet and email have become even more important in recent

They have provided the terror network with new possibilities - but, as the Khan
case illustrates, fresh vulnerabilities too.(...)

"The al-Qaeda ideology can be very well served on the internet. It is able to
purport its agenda, goals and ideology probably better on the internet than any
other means."

(...) the organisation has been forced to evolve and become more decentralised

19.03. After Convictions, the Undoing of a U.S. Terror Prosecution , NY Times

Excerpt: Publicly, federal prosecutors declared in the summer of 2002 that they
had thwarted a "sleeper operational combat cell" based in a dilapidated
apartment here.

Privately, senior Justice Department officials had doubts about the strength of
the case even as they were moving to indict four Middle Eastern immigrants on
terrorism charges. The evidence was "somewhat weak," an internal Justice
Department memorandum obtained by The New York Times acknowledged. (...) But
charging the men with terrorism, the memorandum said, might pressure them to
give up information.

19.04. A New C.I.A. Report Casts Doubt on a Key Terrorist's Tie to Iraq , NY

Excerpt: The new C.I.A. assessment, based largely on information gathered after
the American-led invasion of Iraq in March 2003, is the latest to revise a
prewar intelligence report used by the administration as a central rationale
for war.

Other reports have cast doubt on the idea that Iraq provided chemical and
biological weapons training to Al Qaeda, and the report of the Sept. 11
commission found no "collaborative relationship" between the former Iraqi
government and Al Qaeda.

19.05. Most at Guantanamo to Be Freed or Sent Home, Officer Says , Washington

Excerpt: Most of the alleged al Qaeda and Taliban inmates at the U.S. military
prison at Guantanamo Bay, Cuba, are likely to be freed or sent to their home
countries for further investigation because many pose little threat and are not
providing much valuable intelligence, the facility's deputy commander has said.

The remarks (...) appeared to conflict with past comments by U.S. military
commanders who have stressed the value of the information obtained from the
detainees and the danger many would pose if released.
