Auto apps


Rather than struggle to keep pace with new technology, car manufacturers
are increasingly relying on smartphones to provide tech features….

GPS navigation: A
new $170 portable navigation device is more
accurate and has more features than the built
n $2,000 option the
dealership wants to sell you. That's because it takes years for a car
to make it from the drawing board to the showroom, while new
gadgets and apps appear every day….
automakers like
BMW, Ford,
and GM are changing their tack. Instead of
trying to stuff dashboards
with the latest technology, like gigabytes of memory or dedicated
computer systems, they're designing more streamlined systems that
simply connect to drivers' smartphones…
idea is to rely on those
devices to provide the communicat
ions and computing power to
deliver new services and features. After all, what's more current,

some of the new features, which
include having text messages from an Apple or Android

Ford is
already seen as the leader in automated navigation and
information services in the car, thanks to its Sync system. Sync
is based on a Microsoft service that reads text messages and
recognizes voice co
mmands; with it drivers can ask Sync for
songs from connected MP3 players or request directions to the

Monkey personalities


Most days we want to find a specific monkey or
group of monkeys

wished to do so out of frustration…

their ears or face…As zoologists we don’t like to

research subjects. This is
much easier said than done. Fortunately
anthropomorphizing is not always bad.
gelada has a uni
que personality. An expert
researcher will pick up on these personalities
and use them for identification…
example, one of
unit juveniles is obnoxious

(all females in a
reproductive unit are given names beginning with
the same letter

in this unit al
l of the females
have names beginning with the letter V). She
throws childlike tantrums whenever her mother
doesn’t let her nurse, screaming and yelling until
she gets her way
. This makes
locating her
mother a relatively easy task
. On the other
end of the
spectrum are some absolute
sweethearts. They are calm and don’t antagonize
other monkeys. These monkeys are easy to find in
a unit…


Dung information


colleagues and I are currently studying gelada
reproductive strategies, hormones and genetics.
We can best be described as hunter

But there’s a
We hunt poop…
Gelada society is
complex, with multiple levels of association…One
can obtain all sorts of
information from poop.
What have your research subjects been
eating? Do they have any parasites? How
stressed are they? Is thi
s female cycling,
lactating or pregnant? Does that male have
high or low testosterone? Who is this
baby’s father? Are those two females

To answer each of these questions
requires a different part of the sample

and we
use the entire sample…olleag
ues focus on the
hormonal questions: stress and sex. For this they
collect the homogenized center of the fecal
sample, which contains the relatively stable
hormonal metabolites…I study the genetics. For
this I collect the outer layer of the feces. This
er contains skin cells with valuable genetic
information…Collecting poop is our way of doing
invasive research without being invasive. We
cannot just collect any sample we see. We need to
place the piece of poop into context. For both
genetics and hormones

we need to know the
individual who “gave” us the sample…

Social networks and games


Can your social network make you healthier? It's a question that
health organizations are asking more and more
as part of a wave of
new gaming experiments that aim to persuade players to think an
act differently while having fun…, Vancouver game consulting
company Ayogo launched a Facebook game called HealthSeeker
that awards "life experience" points or virtual gifts when players with
diabetes make small lifestyle changes…hallenge of this kind of

game isn't to convince people of something but to get them to
act…Reinforcing those small actions could turn them into habits that
add up to better health…real power of the game lies in the principle
of reciprocity, the tendency to do something positive f
or someone
who did something positive for you. Game designers take advantage
of reciprocity by making it easy for users to send gifts to friends…In
HealthSeeker, a user can send a "Kudo"
a virtual gift designed to
be interesting or amusing
to reward frie
nds for completing a task
such as going a day without chocolate. When they receive a Kudo,
users feel rewarded and acknowledged for doing something difficult,
Fergusson explains. They will also feel a subtle but powerful
obligation to return the favor…game

also draws on the power of
social networks in other ways. Users can accept challenges from
friends, which Fergusson says make them more likely to take on the
recommended mission (the average player is working on two active
missions; players who have accep
ted a friend's challenge average

psychology is simple but powerful: not only do people like to
win, but they don't like to feel like they've lost something…more and
more industries look to social games to change habits, games can
become a win
situation: the user feels engaged and rewarded
for winning while a company or a society can achieve a critical

that are relations between members of two categories

kind of category or relation with 10 to 15 examples that
are true

“Anger is an emotion.” “Bliss is an emotion.” And about
a dozen more…
NELL gets to work.

Its tools
include programs that extract and classify text phrases
from the Web, programs that look for patterns and
correlations, and programs that learn rules
. For
example, when the computer system reads the phrase
“Pikes Peak,” it studies the structure

two words,
beginning with a capital letter, and the last word is
Peak. That structure alone might make it probable that
Pikes Peak is a mountain. But NELL also reads in
several ways
. It will mine for text phrases that
surround Pikes Peak and similar

noun phrases
repeatedly. For example, “I climbed XXX.”…

“So much
of human language is background knowledge,
knowledge accumulated over time. That’s where
is headed, and the challenge is how to get that

A helping hand from humans,
nally, will be part of the answer. For the first six
months, NELL ran unassisted. But the research team
noticed that while it did well with most categories and
relations, its accuracy on about one
fourth of them
trailed well behind.
Starting in June, the r
began scanning each category and relation for about
five minutes every two weeks. When they find blatant
errors, they label and correct them, putting NELL’s
learning engine back on track…
When Dr. Mitchell
scanned the “baked goods” category recen
tly, he noticed
a clear pattern. NELL was at first quite accurate, easily
identifying all kinds of pies, breads, cakes and cookies
as baked goods.

But things went awry after NELL’s
phrase classifier decided “Internet cookies” was a
baked good….
