A milestone in description of complex processes - measuring the distance of processes - #stationarity #mathematics #stats
A milestone in the description of complex processes -- for example the ups and downs of share prices -- has been reached by mathematicians at the Ruhr-Universität Bochum. Researchers led by Prof. Dr. Holger Dette (stochastics) have developed a new method in spectral analysis, which allows a classical mathematical model assumption, so-called stationarity, to be precisely measured and determined for the first time.
The approach also makes it possible to construct statistical tests that are considerably better and more accurate than previous methods.

#Psychopathic killers: Computerized text analysis uncovers the #word #patterns of a #predator - #criminal #behaviour unmasked
Fascinating. Pay attention.
As words can be the soul's window, scientists are learning to peer through it: Computerized text analysis shows that psychopathic killers make identifiable word choices – beyond conscious control – when talking about their crimes.
This research could lead to new tools for diagnosis and treatment, and have implications law enforcement and social media.
The words of psychopathic murderers match their personalities, which reflect selfishness, detachment from their crimes and emotional flatness, says Jeff Hancock, Cornell professor of computing and information science, and colleagues at the University of British Columbia in the journal Legal and Criminological Psychology.
Hancock and his colleagues analyzed stories told by 14 psychopathic male murderers held in Canadian prisons and compared them with 38 convicted murderers who were not diagnosed as psychopathic. Each subject was asked to describe his crime in detail. Their stories were taped, transcribed and subjected to computer analysis.
Psychopaths used more conjunctions like "because," "since" or "so that," implying that the crime "had to be done" to obtain a particular goal. They used twice as many words relating to physical needs, such as food, sex or money, while non-psychopaths used more words about social needs, including family, religion and spirituality. Unveiling their predatory nature in their own description, the psychopaths often included details of what they had to eat on the day of their crime.
Past as prologue: Psychopaths were more likely to use the past tense, suggesting a detachment from their crimes, say the researchers. They tended to be less fluent in their speech, using more "ums" and "uhs." The exact reason for this is not clear, but the researchers speculate that the psychopath is trying harder to make a positive impression, needing to use more mental effort to frame the story.
"Previous work has looked at how psychopaths use language," Hancock said. "Our paper is the first to show that you can use automated tools to detect the distinct speech patterns of psychopaths." This can be valuable to clinical psychologists, he said, because the approach to treatment of psychopaths can be very different.

Scientists Reconstruct Brains' Visions Into Digital Video In Historic Experiment
An 18-million-second picture paletteIn this other video you can see how this process worked in the three experimental targets. On the top left square you can see the movie the subjects were watching while they were in the fMRI machine. Right below you can see the movie "extracted" from their brain activity. It shows that this technique gives consistent results independent of what's being watched—or who's watching. The three lines of clips next to the left column show the random movies that the computer program used to reconstruct the visual information.

When we take and take and feel entitled, we have lost our purpose. We are then no longer contributing members of society.
If companies build their shareholder value based on community and government support and protection, don't you think they should do the socially responsible thing and pay taxes to share in the collective wellness of the country and its people?
Elizabeth Warren captured the situation in a beautiful statement of facts and truth.
The reason for Warren's newfound Internet stardom is simple. She was able to articulate -- in a few words -- what the Democratic Party has been unable to communicate for years:
"There is nobody in this country who got rich on his own. Nobody.
You built a factory out there? Good for you.
But I want to be clear: you moved your goods to market on the roads the rest of us paid for; you hired workers the rest of us paid to educate; you were safe in your factory because of police forces and fire forces that the rest of us paid for.
You didn't have to worry that marauding bands would come and seize everything at your factory, and hire someone to protect against this, because of the work the rest of us did.
Now look, you built a factory and it turned into something terrific, or a great idea? God bless. Keep a big hunk of it.
But part of the underlying social contract is you take a hunk of that and pay forward for the next kid who comes along."Read the rest of the statement & the story: http://goo.gl/dLuxS

"The components of DNA have now been confirmed to exist in extraterrestrial meteorites. Meteorites hold a record of the chemicals that existed in the early Solar System and that may have been a crucial source of the organic compounds that gave rise to life on Earth. Since the 1960s, scientists have been trying to find proof that nucleobases, the building blocks of our genetic material, came to Earth on meteorites.

Is meditation "push-ups" for the brain?

(Medical Xpress) -- People often share stories, news, and information with the people around them. We forward online articles to our friends, share stories with our co-workers at the water cooler, and pass along rumors to our neighbors. Such social transmission has been going on for thousands of years, and the advent of social technologies like texting, Facebook, and other social media sites has only made it faster and easier to share content with others. But why is certain content shared more than others and what drives people to share?
Well, according to Jonah Berger, the author of a new study published in Psychological Science, a journal of the Association for Psychological Science, the sharing of stories or information may be driven in part by arousal. When people are physiologically aroused, whether due to emotional stimuli or otherwise, the autonomic nervous is activated, which then boosts social transmission. Simply put, evoking certain emotions can help increase the chance a message is shared.
“In a prior paper, we found that emotion plays a big role in which New York Times articles make the most emailed list. But interestingly, we found that while articles evoking more positive emotions were generally more viral, some negative emotions like anxiety and anger actually increased transmission while others like sadness decreased it. In trying to understand why, it seemed like arousal might be a key factor,” says Berger, the Joseph G. Campbell Jr. Assistant Professor of Marketing at the University of Pennsylvania.

I wanted to reference this again after speaking at the Global Innovation Forum Silicon Valley a couple of weeks ago about Innovation & The Millennials. There are so many opportunities to create situations for older and younger to work together to shape the future, starting immediately. This cross-generational sharing could transform our communities and work places. Visiting the USA, I notice more and more older people working in stores - we never see that in The Netherlands.
My mother just started her 89th year on this planet. She has also just started a new career - sharing her experience on suffering, loss and grief with others who are struggling with those issues. This makes her feel valuable, worthy and keeps her feeling vital. Inspiration for others.

As Populations Age, a Chance for Younger Nations
By TED C. FISHMAN
Published: October 14, 2010
" YOU MAY KNOW that the world’s population is aging — that the number of older people is expanding faster than the number of young — but you probably don’t realize how fast this is happening. Right now, the world is evenly divided between those under 28 and those over 28. By midcentury, the median age will have risen to 40. Demographers also use another measure, in addition to median age, to determine whether populations are aging: “elder share.” If the share, or proportion, of people over 60 (or sometimes 65) is growing, the population is aging. By that yardstick too, the world is quickly becoming older.
Pick any age cohort above the median age of 28 and you’ll find its share of the global population rising faster than that of any segment below the median. By 2018, 65-year-olds, for example, will outnumber those under 5 — a historic first. In 2050, developed countries are on track to have half as many people under 15 as they do over 60. In short, the age mix of the world is turning upside down and at unprecedented rates. "
