Posted: 17 Apr 2010 03:11 PM PDT I launched the world's first elective course at a medical university focusing on web 2.0 and medicine for medical students in 2008. Now this is the 4th semester and the 8th week was dedicated to new media in medicine and education 2.0. Here is the outline of my presentations. First slideshow: New Media in Medicine
 Take-home message: Make your online work as efficient and time-saving as possible. Second slideshow: Education 2.0

Posted: 17 Apr 2010 01:31 AM PDT  Some have suggested that this has been a big PR disaster for Ning, others that this could mean the end to free social media, whilst many more have focused on the alternatives to Ning. I wrote a blog posting on my Social Media in Learning blog about how I thought Elgg might be a good alternative. However there have been many other suggestions, some of which I actually don't think would provide the same functionality as Ning, so this is the reason for today's blog posting, as I wanted to remind you about the section in the Directory of Learning Tools, that (currently) lists 115 social networking and collaboration space tools and services. In this list you will find
You may find my comparison of Facebook, Ning and Elgg a useful resource when considering all the factors involved - to ensure you don't jump out of the frying pan into the fire! Meanwhile, you should also note that Ning has made the following announcement on its blog: "We recognize that there are many active Ning Networks for teachers, small non-profits, and individuals and it's our goal to have a set of product and pricing options that will make sense for all of them."Decisions, decisons .. | |||||||||||||||||||||||||||||
Posted: 15 Apr 2010 11:25 AM PDT Big news today from Ning: no more free networks (and 40% staff layoffs). Hosted services are great – as long as you can pull your data out (a significant value to Google's data liberation project). Many educators use Ning for creating social networks. But, for Ning, ad revenue has not been able to meet their financial needs. Which is why I'm quite pleased that we're using Elgg for our institutional learning/collaboration network at Athabasca University: the Landing. If you decide not to host your own site, at least make sure you can own and export your own data on your terms. Is this a commentary on "free" as a business model? | |||||||||||||||||||||||||||||
Posted: 15 Apr 2010 08:15 AM PDT  Serum 25-hydroxyvitamin D (25-OHD) levels were measured in 414 (ex)-smokers older than 50 years and the link between vitamin D status and presence of COPD was assessed. The rs7041 and rs4588 variants in the vitamin D-binding gene (GC) were genotyped and their effects on 25-OHD levels were tested.In patients with COPD, 25-OHD levels correlated significantly with forced expiratory volume in 1 s (FEV1). Compared with 31% of the smokers with normal lung function, as many as 60% and 77% of patients with GOLD (Global Initiative for Obstructive Lung Disease) stage 3 and 4 exhibited deficient 25-OHD levels lower than 20 ng/ml. 25-OHD levels were reduced by 25% in homozygous carriers of the rs7041 at-risk allele. 76% and 100% of patients with GOLD stage 3 and 4 homozygous for the rs7041 allele exhibited 25-OHD levels lower than 20 ng/ml. Vitamin D deficiency occurs frequently in COPD and correlates with severity of COPD. The data warrant vitamin D supplementation in patients with severe COPD, especially in those carrying at-risk rs7041 variants.

Gartner (a Swahili term meaning "first we will make you give us a bunch of data to register for our site and then we'll charge you a few thousand dollars for simple research reports") is jumping on the touch mania that will continue to grow as more companies release their tablets/slates stating that "50% of the computers purchased for children will have touchscreens by 2015″. I can certainly understand the value of touch over keyboard and mouse interfaces. Children interact almost intuitively with touch interfaces. I'm reluctant to ascribe far-reaching educational implication to this, however. While pundits shall come a'runnin', learning implications are far from clear.
