01. The Impact of Political Advertising on Knowledge, Internet Information
Seeking, and Candidate Preference , J. Communication

Excerpts: Previous research has suggested that exposure to political
advertising is generally informative and may even reduce information gaps
between the most and least aware in society, but does not produce large shifts
in candidate preference. Drawing on extant models of opinion change, we
predicted that the informational benefits of political ads would vary by level
of awareness, such that the most aware would experience the largest gains,
especially when they are asked to make inferences about issues not explicitly
discussed in the ad. Further, (...) most aware would use information in
advertisements as a substitute for other kinds of information seeking, (...).

01.01. Social Structure and Opinion Formation , arXiv

Excerpt: We present a dynamical theory of opinion formation that takes
explicitly into account the structure of the social network in which
individuals are embedded. The theory predicts the evolution of a set of
opinions through the social network and establishes the existence of a
martingale property, i.e. that the expected weighted fraction of the population
that holds a given opinion is constant in time. Most importantly, this weighted
fraction is not either zero or one, but corresponds to a non-trivial
distribution of opinions in the long time limit. This co-existence of opinions
within a social network is in agreement with the often observed locality effect

01.02. Phase Transitions for Rock-Scissors-Paper Game on Different Networks ,

Abstract: Monte Carlo simulations and dynamical mean-field approximations are
performed to study the phase transitions in rock-scissors-paper game on
different host networks. These graphs are originated from lattices by
introducing quenched and annealed randomness simultaneously. In the resulting
phase diagrams three different stationary states are identified for all
structures. The comparison of results on different networks suggests that the
value of clustering coefficient plays an irrelevant role in the emergence of a
global oscillating phase. The critical behavior of phase transitions seems to
be universal and can be described by the same exponents.

02. How Love Evolved From Sex And Gave Birth To Intelligence And Human Nature ,
J. Bioecon.

Excerpts: This article argues that emotional attachment drive has shaped the
evolution of human intelligence, interpersonal relationships and culture. The
first section is about the evolution of social bonds and their role in the rise
of intelligence. At the outset, I present evidence that desire for emotional
closeness to others is a primary human instinct. Recent discoveries in
neurobiology are then incorporated into a summary of the evolution of brain
systems that activate emotional attachments (...). The evolution of maternal
behavior is discussed as a particularly important event enabling expansion of
brain size and complexity (...) leading ultimately to the modern human brain.

02.01. From Nosy Neighbors to Cultural Evolution , Science

Excerpts: Psychologists, economists, and advertising moguls have long known
that human decision-making is strongly influenced by the behavior of others. A
rapidly accumulating body of evidence suggests that the same is true in
animals. Individuals can use information arising from cues inadvertently
produced by the behavior of other individuals with similar requirements. Many
of these cues provide public information about the quality of alternatives. The
use of public information is taxonomically widespread and can enhance fitness.
Public information can lead to cultural evolution, which we suggest may then
affect biological evolution.

03. Here Comes The MP3 Revolution , Contra Costa Times

Excerpts: While the record companies battled Napster and so-called music piracy
in court, tech companies saw a different future in other statistics: namely,
that at least 33 percent of obtainable music will be delivered digitally within
five years. Voila -- along comes the MP3 player and the current benchmark, the
iPod, bypassing CD burning and eliminating the CD. Users instead download music
onto a handheld computer that, essentially, acts like a mini jukebox without
the physical records.

Only this jukebox costs about $400 and holds up to 15,000 songs, (...).

04. Traffic Forecast In Large Scale Freeway Networks , Int. J. Bifur. & Chaos

Excerpts: Traffic flow in large and complex freeway networks is a highly
nonlinear phenomenon, which makes traffic forecast a difficult task. In this
article an approach to traffic forecast is presented, which uses a
micro-simulator for traffic flow combined with current and historical traffic
data. The micro-simulator and locally measured current traffic data are used to
reconstruct the current network-wide traffic state. (...) The micro-simulator
uses an advanced cellular-automaton model for traffic flow, and the data are
supplied from more than 4,000 locally installed loop-detectors, which deliver
information on the (local) traffic state online minute by minute.

04.01. The Value Of Snowfall To Skiers And Boarders , Env. & Resource Econ.

Abstract: An interesting winter sport phenomenon in recent years has been the
growth of snowboarding. Snowboarding has outpaced skiing at many resorts and
has become the snow riding activity of choice for many young people. This study
develops an empirical demand model for winter sport trips amongst college
students from both camps and estimates economic welfare associated with the two
different activities. The results show that both trip demand and surplus values
are strongly affected by snow conditions. These effects are distinctly
different for the two consumer groups.

05. Technological Networks and the Spread of Computer Viruses , arXiv

Abstract: Computer infections such as viruses and worms spread over networks of
contacts between computers, with different types of networks being exploited by
different types of infections. Here we analyze the structures of several of
these networks, exploring their implications for modes of spread and the
control of infection. We argue that vaccination strategies that focus on a
limited number of network nodes, whether targeted or randomly chosen, are in
many cases unlikely to be effective. An alternative dynamic mechanism for the
control of contagion, called throttling, is introduced and argued to be
effective under a range of conditions.

06. Biodiversity: A Tragedy With Many Players , Nature

Excerpts: Peter Ng is a man with a mission: to catalogue the huge diversity of
life dwelling in habitats long dismissed as uninteresting. (...)

The peat swamps, in particular, are being drained as fast as he can sample
them, sometimes for urban or agricultural development, at other times ?in a
bitter irony ?under the guise of 'environmental improvement'.

The rich faunas found in such neglected habitats underline a growing
realization that conservation biologists really know very little about our
planet's biodiversity (...).

06.01. Population Variation In Lateralised Eye Use , Alphagalileo & Biol. Lett.

Excerpts: It is well known that humans, and virtually all other vertebrates,
use one side of their brain for some tasks and the other side for other tasks
(lateralisation). Evolutionary biologists have struggled to explain why
lateralisation initially arose and why it persists. (...) shown that the
pattern of lateralisation within a species varies depending on the level of
predation pressure present in the environment, suggesting that various
ecological pressures shape the relative costs and benefits associated with the
development of lateralised brains. Their discovery has considerable
implications for the understanding of the evolution of brain lateralization in
all animals including humans.

07. Human Intelligence Determined By Volume And Location Of Gray Matter Tissue
In Brain , Today@UCI


Areas in brain activated by IQ testing

General human intelligence appears to be based on the volume of gray matter
tissue in certain regions of the brain, (...).

(...) because these regions related to intelligence are located throughout the
brain, a single ntelligence center,?such as the frontal lobe, is unlikely.
Previous research had shown that larger brains are weakly related to higher IQ,
but this study is the first to demonstrate that gray matter in specific regions
in the brain is more related to IQ than is overall size. Multiple brain areas
are related to IQ,

07.01. Epileptic Neurons Go Wireless , Science

Excerpts: The idea that "neurons that fire together, wire together" is well
established in developmental neuroscience. (...) neurons that fire action
potentials at the same time are more likely to develop synaptic connections
with each other. In epilepsy, this process is taken to an unhealthy extreme:
Neurons that fire together during seizures wire together through a process
called axonal sprouting. (...) some of the positive feedback that underlies the
epileptic condition may be formed "wirelessly"--that is, using a mechanism that
does not involve growth of new axons or synaptic connections.

08. Children Think Before They Speak , Nature

Excerpts: A linguistic contrast between English and Korean provides a telling
test of different ideas about whether thought precedes the acquisition of
language, or whether certain concepts are language-specific.

For Augustine, thought precedes language: language is a tool with which to
express one's ideas and to understand the ideas of others. (...) Many scholars
would instead endorse the theory of linguistic relativity, and maintain that
learning a language has a profound influence on a child's mental life. If so,
then speakers of different languages might think in very different ways.

08.01. Conceptual Precursors To Language , Nature

Excerpts: Because human languages vary in sound and meaning, children must
learn which distinctions their language uses. For speech perception, this
learning is selective: (...); however, infants' sensitivity to non-native sound
distinctions declines over the course of the first year. Here we ask whether a
similar process governs learning of word meanings. We investigated the
sensitivity of 5-month-old infants in an English-speaking environment to a
conceptual distinction that is marked in Korean but not English; (...).
Language learning therefore seems to develop by linking linguistic forms to
universal, pre-existing representations of sound and meaning.

08.02. Stuttering More Than Talk - Research Shows Brain's Role In Disorder ,

Excerpts: New research from Purdue University shows that even when people who
stutter are not speaking, their brains process language differently.
"Traditionally, stuttering is thought of as a problem with how someone speaks,
and little attention has been given to the complex interactions between
neurological systems that underlie speaking, (...) We have found differences in
adults who stutter, compared to those who don't, in how the brain processes
information when people are thinking about language but not speaking. For
example, there was a significant delay in response time when subjects were
given a complex language task. (...)"

09. Audience Drives Male Songbird Response To Partner's Voice , Nature

Excerpts: (...), avian communication generally takes place in a network of
signallers and receivers, which represents an audience altering individual
signalling behaviours. (...). This 'audience effect' provides support for the
reality of social awareness in some bird species. However no evidence has yet
been found to suggest that birds are able to estimate the characteristics of
the social relationships between group-mates. Here we show that the male of
(...) the zebra finch (...) ays attention to the mating status of conspecific
pairs, and uses this information to control its behaviour towards its female

Excerpts: An indicator of animal intelligence is thought to be the ability to

(...) female zebra finches can recognize their mate, with whom they form
lasting pair bonds, by his 'distance call', (...). But (...) male zebra finches
did not recognize their mate through female distance calls. (...)
One overlooked factor was the context in which these recognition tests were
conducted. The birds, normally members of large flocks in the wild or large
groups in captivity, had been tested while alone.

09.02. Coalition Among Male Fiddler Crabs , Nature

Excerpts: Seeing off a neighbour's intruder may be easier than negotiating with
a larger usurper.

Until now, no compelling evidence has emerged from studies of animal
territoriality to indicate that a resident will strategically help a neighbour
to defend its territory against an intruder. We show here that territory-owning
Australian fiddler crabs will judiciously assist other crabs in defending their
neighbouring territories. This cooperation supports the prediction that it is
sometimes less costly to assist a familiar neighbour than to renegotiate
boundaries with a new, and possibly stronger, neighbour.

10. Toward A 0th Law Of Thermodynamics: Order-Creation Complexity Dynamics , J.

Excerpts: (...) A more recent view is that the most significant dynamics in
bio- and econospheres are not variances around equilibria. Instead order is now
seen to be due to the interactions of autonomous, heterogeneous agents
energized by contextually imposed tensions (...) also calls for a change away
from the definition of science rooted in the equilibrium mathematics of
Newton's orbital mechanics. This new message from natural science is about
rapid-fire dynamics calling for a fast-motion science of order-creation before
the equilibria of the 1st Law (...). The possibility of a 0th law - of agents'
self-organization toward order creation - is considered. (...)

The basic argument for parallel universes goes like this: Space is infinite.
Within any finite volume of space, however, matter and energy can be arranged
in only a finite number of ways. So if you carve space into enough same-sized
regions, sooner or later they will start repeating themselves.

Excerpts: Scientists believe they can beat cancer by taking advantage of its

Bart's and Queen Mary's School of Medicine and Dentistry have created a
modified virus that will do just that. The virus lacks a gene viruses normally
use to disguise themselves so they can sneak into the cell unnoticed. Normal
cells can recognise they are under attack by the modified virus and commit
suicide to prevent it from replicating and infecting other cells. Cancer cells
are programmed differently and resist suicide at all costs. This "selfishness"
on the cancer's behalf allows the engineered virus to replicate within the
cancer cells and spread through the tumour tissue.

process. Many different cell types and proteins have been linked to the repair
process, but the complexity of the mammalian wound response has challenged
efforts to determine their individual roles. (...) After stabbing fruitfly
larvae with a needle to create a nonfatal puncture wound, the researchers

promote healing. (...)

Excerpts: It is a quirk of the F.D.A.'s labeling rules. For a drug's
government-approved uses, the label gives doctors important data from clinical
tests involving those treatments while spelling out the drug's risks and
providing directions for administering it to patients.

But labels are often allowed to remain silent about a test when the F.D.A.

to combat terrorist financiers
