Models for Cognition: Belief vs Connectionism; links on writing style

There's an interesting article about the consequences of connectionist models for the theory of beliefs. I think it's interesting that one counterexample is taken as a proof for the non-existence of beliefs, whereas a lot of further contraints (for biological and evolutionary reasons) might apply to require the construction to be more uniform/unique.

Search engines and market forces

Friedman claimed that if there's demand for some sort of goods or goods with special attributes (like being produced in an environtment-friedly process, by high paid workers, ...) the market will create adequate products - as long as demand means the willingness of the consumers to pay for that special property they request.

Some rather unknown examples or at least rarely used examples for this are "green" or CO2-neutral servers and online services. For search engines, there are several alternatives:

• Forestle promises to enable its partner, the US based organisation "The Nature Conservancy" to reforest 0.1 m^2 of rain forest for every search.
  
• Ecosia supports the WWF in protecting rain forest in Brasil, on average about 2 m^2 per search
  
  The backend of forestle and ecosia is provided by Bing and Yahoo. The operator for both is a for-profit organisation located in Berlin, Germany, which is bound by contract to invest at least 80% of its earnings in these rain forest projects.
  
  
• znout doesn't support anyone, but buys enough CO2-certificates to green-ify the power used by the servers in the search process. Its also the only search engine that uses google (the custom search provided by google)
  
• GoodSearch offers you to choose a US-based charity to give the money to - on average 0.01 USD per search. It features, among many others, amnesty international and the Richard Dawkins Foundation for Reason and Science. Its again a front-end to Yahoo search technology.
  

All search engine providers generate their money via advertisment on the search pages.

Writing systems and non-linearity

Some time ago I posted some links, one of them pointing to a non-linear, graph like writing system called Ouwi; meanwhile I spent some time reading up on the topic of writing systems and have some more pointers:

Pinuyo is a pictorial language which indicates grammatical function of the ideograms by placement and surrounding symbols.

I also found a long, but sometimes deviating thread on 2-dimensional writing systems on the conlang mailing list archive. Unfortunatelly many of the links are now dead, the thread is from 2005.

Omniglot is a nice website about alphabets, writing systems and languages. It contains some constructed systems, like block script, a sylabic alphabet for the english language which combines letters to blocks (like the korean script for example). Most of them are linear ones.

I'm still wondering if there are some languages/alphabets optimized for reading speed. Most are either evolved, natural languages, which certainly are a compromise between reading and writing and the constructed ones optimized for speed like the morse code or shorthand.

In an edit, let me just add a few more links, somewhat related:

Láadan, a feminist language designed for countering male-centering of natural languages.

(dual) n back

I just learnt about the concept of n back tests. Basically, you are presented tokens from a sequence and your task is to determine whether the current token matches the token N steps back.
This can of course be done in parallel with multiple sequences, called "dual", "triple" (..) N-Back, although I haven't seen any implementation of a triple (k, m, n)-Back with different periods in each sequence.

There is a paper which claims to establish a connection between playing dual n back and fluid intelligence. There is also a wired article summarizing the paper.
