Feedback from friends posted publicly on people's profiles also tend to be overwhelmingly positive, which can further boost self-esteem, said Hancock, who co-authored a paper published Feb. 24 in the journal Cyberpsychology, Behavior and Social Networking."Unlike a mirror, which reminds us of who we really are and may have a negative effect on self-esteem if that image does not match with our ideal, Facebook can show a positive version of ourselves," Hancock said. "We're not saying that it's a deceptive version of self, but it's a positive one."It may be one of the reasons why Facebook has 500 million users, who spend more than 700 billion minutes per month communicating with their friends via photos, links and status updates."For many people, there's an automatic assumption that the Internet is bad. This is one of the first studies to show that there's a psychological benefit of Facebook," Hancock said.

The researchers found that fulfillment of a diversity of needs, as defined by Maslow, do appear to be universal and important to individual happiness. But the order in which "higher" and "lower" needs are met has little bearing on how much they contribute to life satisfaction and enjoyment, Diener said. They also found that the fulfillment of more basic needs - for money, food or shelter, for example - was more closely linked to a positive life evaluation, the way an individual ranked his or her life on a scale from worst to best. The satisfaction of higher needs - for social support, respect, autonomy or mastery - was "more strongly related to enjoying life - having more positive feelings and less negative feelings," Diener said. An important finding, Diener said, is that the research indicated that people have higher life evaluations when others in society also have their needs fulfilled.

"Effective teamwork among an organization's top management makes employees happier and more productive, with positive benefits to the organization."

"The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds-fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself. We apply fight-or-flight reflexes not only to predators, but to data itself. We're not driven only by emotions, of course-we also reason, deliberate. But reasoning comes later, works slower-and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about."

"Why the increasing business use of social media by business? Social media offers immense potential for marketing, image-making, advertising, public relations efforts, customer relations, investor relations and a variety of other positive, beneficial activities.  But it also carries potential risks, a caveat perfectly illustrated by the Hastings case. The risks of social media are in some, but not all respects, similar to those of print media.  But not all libel laws apply-issues of malice and negligence have not been definitively decided in the courts. Insider trading issues, however, are clear.  The transmission via social media of insider information about a publicly traded company is illegal. Using Facebook, Twitter, Pinterest or private blogs to transmit insider information to large numbers of people is a violation of law."

"Australian-based collaboration design specialist Matt Cooperrider has begun to explore an idea that I think the GeekDad readership is more than well positioned to help with. As well as being one of those out-of-the-box thinkers and generally smart guys, Matt is also a role-player and geek at heart. He has begun a new project called Play to Decide which will research how role-playing games can be used to support organizations and communities in democratic decision-making and the collaboration that follows. "

Despite a shaky economy, many web companies are in hypergrowth.  This is reminiscent of the five-year period over a decade ago when companies like Amazon, Netscape, eBay, Yahoo, Google and PayPal were built. One challenge, which isn't new, is the battle for consumer attention.  If you're looking to grow your user base, is there a best way to cost-effectively attract valuable users?  I'm increasingly convinced the best way is by harnessing a concept called social proof, a relatively untapped gold mine in the age of the social web. What is social proof?  Put simply, it's the positive influence created when someone finds out that others are doing something.  It's also known as informational social influence.

Sweden has surrendered its official Twitter account, @sweden, to the hoi polloi. The project, Curators of Sweden, signs up Swedes to tweet a week at a time. It started December 10 with Jack Wermer, a writer and marketing specialist. The second tweeter was Hasan Ramic, a Bosnian immigrant Currently, the position is filled by the moose-hunting, oral tobacco product enthusiast Anders Dalenius.

The New Yorker's Malcolm Gladwell is a very smart writer with a knack for smart, provocative, "contrarian" statements. One such argument that gets digerati in a tizzy is the idea that social media actually doesn't help bring down oppressive regimes, despite all the hype. That debate is back in the news with the protests in Egypt. We'll say right off the bat that we're skeptics that social media can bring down oppressive regimes. We believe Twitter makes a tangible, positive difference in the real world, but probably not quite at the level of regime change. But Gladwell wrote a blog post yesterday on social media and Egypt that just doesn't make any sense.

According to new statistics from analytics firm Flurry, the average mobile user now spends 9% more time using mobile apps than the Internet. That's 81 minutes per day for mobile apps versus 74 minutes per day spent surfing the Web (both desktop and mobile). But mobile apps haven't always been more popular than the Web, says Flurry. Only last year, these positions were reversed, with users spending 43 minutes on apps versus 64 minutes on the Web.

The results of this research project reveal that female directors are willing to tackle tough issues that are often considered unpalatable by all-male boards. Female board participation is also found to lead to more effective board communication with investors. The presence of female directors in monitor positions on audit and corporate governance committees also makes for more transparent reporting and earnings quality. There is evidence that boards with female directors promote greater vigilance over financial reporting, exhibit greater independence of though and ensure a more rigorous monitoring process.

Does your company have a strategy? Freek Vermeulen doubts it. And he posits the five main reasons why, too often, a firm's strategy is nothing more than a pipe dream.

Next time you feel like broadcasting some gloomy tale of woe on Facebook, you might want to think twice. Your friends could catch your feelings. Psychologists have long known that emotions, just like germs, are contagious. People exposed to a person experiencing strong emotions may experience similar feelings, catching them through facial expressions, tones of voice or some other means. But now there is a new means of transmission -- social media. Facebook data scientist Adam D.I. Kramer analyzed postings by about 1 million English speakers and their roughly 150 million friends in multiple countries on the social network to show that the words people use in their status updates drive the emotions of their online friends, even days later. Kramer found people who used emotionally loaded words like "happy," "hug," "sick," and "vile" in their status updates sparked similar emotions in later Facebook postings by their friends.
