I have added a simple DCM model renderer script called
dcm2dot to my
With this function DCM model files (DCMxxx.mat) will
be analysed and their network written out as
.dot files. You then can use graphviz small programs
like dot to render the network to PNG, PDF, SVG, etc.
Here a simple example of a V1-MT+ DCM:
I have added a short script that will estimate all available DCM models within a directory to my SPM Hacks page. This is a simple way to get parallel DCM Model estimation without a dedicated PC cluster and works also with multiple PCs if you put the files on a network file system. Note however that matlab uses one licence per user per PC, so you may run out of licences fast. But if you have a 8 core Linux PC you may be able to estimate 8 models at the same time in 8 matlab sessions using just one licence.
There was a time when
was the fastest and the best webbrowser on the mac. It
was my default browser for more than 3 years. But one
thing has changed it all:
It started small, like only one annoying flash applet on webpages that I used to read. It wasn't doing much that could not be achieved with animated gif or png. Apart from eating like 100 times the CPU power.
It did not worry me that much, I could set most of them to "hidden" with my user stylesheet in Safari. I did not notice that people all around me started cutting down the number of open pages in their browsers to only one, so that their computer did not slow down to a crawl.
Switch to Firefox. Install the Flashblock-addon. And there is no step three.
The german newspaper "Spiegel" writes in
Deutsche Manager fallen
bei Finanzinvestoren durch (losly
translate-able as "german managers having a hard time
with their investors"):
"Mit Praxiserfahrung meinen die Investoren jedoch nicht die Kenntnis der Branche, sondern ein generelles Verständnis der Abläufe in Unternehmen. Sie verstehen darunter auch nicht Expertenwissen, denn das, so argumentieren die Befragten, könne man im Markt 'billig einkaufen'."
("By practical knowledge the investors do not mean the knowledge of the field of the company but a general understanding of the operations within companies. Also they do not mean expertise, because that can be bought cheaply on the market")
Ignoring the fact that it is almost best not to believe anything written in the german press (speaking of this, where are the articles about companies moules in german ministeries?) this is still very interesting.
If I do not have expertise on the field of the company, how can I decide wether the cheap expert has sound knowledge of the field or wether he is just giving the impression that he has it?
It is difficult and time-consuming to gain expertise. If the expert is really cheap he simply can not be very good (or the market has gone insane). But the price alone is no good indicator either. A expensive fraudster will appear better than a expensive expert because he will gain more money and can put the saved work in better advertising.
Web-Designer: Since the web has gone mainstream, self called experts keep on telling that the consumers like hugh colourful websites full of flash. The reality is quite different: of all search engines only the most minimalistic Google prevailed. And thinking about auction websites, today there is only the in comparison more minimalistic left: Ebay.
Apple: Since Steve Jobs returned to the company the tide has changed and Apple gains more and more money. The company is known for the ease-of-use of their products and people in marketing all around the world are wondering how a product that has less features and a higher price can gain the highest market share in a consumer market. Obviously Jobs has the expertise to "buy" the best expert. Speaking of buy - the experts are not bought at Apple. They are contracted workers.
If you life in Barcelona you quickly notice that
Barcelona is a very special city. In Barcelona
everything is special.
The aquarium for example. 15.50 EUR for a, well ok, it is big, shark basin, some very small fish tanks and a big gift shop (that you can enter without paying). In caixa's science museum you can see much more and the basic entrance of 3 EUR is surprisingly cheap (but you have to pay extra for almost everything you want to see).
Or the poble español (spanish village). 7.50 EUR to enter a shopping mall that is built like some houses in spanish cities. Don't expect something like a museum.
Finally, Night Life! Want to spend some hundreds of euros in one night? No problem in the center or on the beach, in the clubs and the discotheques. But yet close to the centre, in the Eixample, you may run into problems because the bars there close at 10 o' clock and thats it. Well, Barcelona is not Spain. Try not to forget it.
All in all, everything in Barcelona is special. Because it is in Barcelona.
PS: And don't get me started on the things they call "Tapas" here.
