Short cartoon video on the subject of deduction by computers of your friends, habits and messages in order to read your mind
Think you can hide your personal data by choosing not to reveal information online?
Even if you’re a social media prude, advanced software algorithms can glean a surprising amount of detail about your life. For example, even though most people on Facebook choose not to reveal their physical addresses, it’s possible to infer the general location of the majority of users based on the few who do. Similar software can figure out who is likely to be your friend and what kind of personality you might have.
From New Scientist
An interesting article in PLos One on an online networking service that is very popular in The Netherlands. It has a relatively large proportion of the population as members. The author used a dataset obtained from this Dutch service: Hyves.
Some interesting results from this extensive data analyses.
- Young people roughly between 10 and 25 years of age are overrepresented as a share of the population, more demographic facts can be found in the free accessible article published in PLos One
- The structure of the Hyves network follows the regularities found in other large complex networks. This can be summarized as two different kind of distributions. Core densities with the ability to a quick spreading through the whole network. In other words, small network nodes of separate small worlds in which sometimes news spreads very rapid through the whole network. The same principle as in the epidemiological literature, a core-periphery structure that is believed to facilitate the spread of diseases
- A substantial fraction have no Friends at all. Those with friends have on average 106 friends
The short conclusion is that a comparison with other online social networks such as facebook shows that these networks show remarkable similarities.
Empathy, cooperation, fairness and reciprocity — caring about the well-being of others seems like a very human trait. But Frans de Waal shares some surprising videos of behavioral tests, on primates and other mammals, that show how many of these moral traits all of us share.
Excellent lecture by one of the great Dutch scientists.
In a blog post with the title: Harnessing the Collective Intelligence the author of the blog The Amazing World of Psychiatry wrote an extensive review of the blogs written by psychiatrists with links to pages of interest. The most important blogs written by psychiatrists in the Blogosphere are securely reviewed and links to several posts are provided with a short introduction. An excellent review
Throughout this blog, I have reviewed numerous other blogs and in so doing have curated a very small part of the web. The reviews have been my opinions and interpretations of the blogs and have included links to pages I thought were of interest in these blogs. In a sense this is my interpretation of this part of the web. However because I am interpreting other people’s blogs, I am in a sense interpreting other people’s interpretations of the web. In so doing, this is the harnessing of collective intelligence.
During our annual conference of the Dutch Association for Psychiatry we had an interesting discussion about the use of twitter for psychiatrists. Ethical as well as practical aspects of the use of twitter were discussed. The main question from the audience was: Why should we use twitter. We hope we could convince some of them of the advantages of using twitter.
My part of the session was a Twitter for Dummies session. In a short presentation I mentioned the most important rules to obey when starting with twitter as a physician.
In short these rules were:
- Use a short username with as few characters as possible since that name will be used to communicat with you on twitter in replies (@ messages) and direct messages (DM)
- When registering your twitter account make sure to provide a link for more information about yourself. I use a twitter landing page on my blog but most physicians as well as psychiatrists have a LinkedIn account. Use the link to your LikedIn account for more information about yourself
- Use a clear and nice picture of yourself as avatar, spent some money on a professional photographer to make a couple of pictures. They are always useful not only for on the web but also for several different badges and documents. Worth the money
- Never, ever use twitter anonymously as a physician. Patients rely on doctors for trustworthy information so let them be able to check your credentials
- Use your own background. They are easy to make or buy from several designers. If you have a website, logo, blog or any other way of publicly expressing yourself make sure the lay out of all these forms are more or less the same. Use at least the same colors, be recognizable on the web.
- You don’t have to follow those who are following you. In the beginning all the information might be overwhelming so start slow in following your followers
- Get acquainted with the jargon such as @ messages, DM’s and hashtags
- Use excellent software on your desktop such as seesmic or tweetdeck. Use a twitter client on your mobile devices
- Try it for at least three weeks
- A good to excellent book for twitter beginners is The Twitter Book by Tim O’Reilly and Sarah Milstein. I tried them all, this was simply the best
