Sandra Fisher-Martins: O direito a perceber - Video TED
Sandra Fisher-Martins: The right to understand | Video on TED.com
Não sabia que as conferências TED estavam já a ocorrer em Portugal - a intervenção é em português. Vejam os comentários, que alguns são mesmo interessantes.
Medical, legal, and financial documents should be easy to read, but too often they aren’t. With spot-on (and funny) examples, Sandra Fisher Martins shows how overly complex language separates us from the information we need -- and three steps to change that. In Portuguese with English subtitles.

Também tem a ver com desigualdade ... | Video on TED.com
What was the greatest invention of the industrial revolution? Hans Rosling makes the case for the washing machine. With newly designed graphics from Gapminder, Rosling shows us the magic that pops up when economic growth and electricity turn a boring wash day into an intellectual day of reading.
De como a desigualdade prejudica as sociedades (nomeadamente, a nossa)| Video on TED.com
We feel instinctively that societies with huge income gaps are somehow going wrong. Richard Wilkinson charts the hard data on economic inequality, and shows what gets worse when rich and poor are too far apart: real effects on health, lifespan, even such basic values as trust.
Um dos factores que devem ser tidos em linha de conta para perceber o que se passa tem a ver com as consequências, não só sociais, mas também económicas e psicológicas, da desigualdade. O que se diz nesta intervenção a esse propósito é exemplar. A demonstração gráfica é-o igualmente. Ter em atenção o posicionamento de Portugal. Uma dica (no caso de não se lembrarem): a melhor forma de inspecionar os gráficos é suspender a passagem do vídeo.

Os algoritmos como força coevolutiva, ou um sinal dos tempos, ou é necessário ter cuidado, ou não se pode ser complacente ...
Kevin Slavin argues that we're living in a world designed for -- and increasingly controlled by -- algorithms. In this riveting talk from TEDGlobal, he shows how these complex computer programs determine: espionage tactics, stock prices, movie scripts, and architecture. And he warns that we are writing code we can't understand, with implications we can't control.
Isto é sobre intervenções, nomeadamente, a intervenção no Afeganistão, mas a lição a retirar é de dominio de aplicação muito mais lato.
British MP Rory Stewart walked across Afghanistan after 9/11, talking with citizens and warlords alike. Now, a decade later, he asks: Why are Western and coalition forces still fighting there? He shares lessons from past military interventions that worked -- Bosnia, for instance -- and shows that humility and local expertise are the keys to success.

Porque razão os movimentos sociais com mais sucesso são extremistas? ou, nesta narrativa existem ensinamentos a retirar para nós outros?
Why do transnational extremist organizations succeed where democratic movements have a harder time taking hold? Maajid Nawaz, a former Islamist extremist, asks for new grassroots stories and global social activism to spread democracy in the face of nationalism and xenophobia. A powerful talk from TEDGlobal 2011.
Interessante, mas, para mim, ainda mais interessante é o que nos pode ensinar sobre o que deveria ser feito nas nossas próprias sociedades onde democracia é, efectivamente, um estado civilizacional, ainda que não tão enraizada, forte, eficaz, como isso - o carácter de um estado civilizacional, a sua resiliência, depende de como responde às grandes crises, e as grandes crises: políticas, económicas, sociais, por vezes transformam-se em crises civilizacionais.

Apatia e participação
"About this talk
Local politics -- schools, zoning, council elections -- hit us where we live. So why don't more of us actually get involved? Is it apathy? Dave Meslin says no. He identifies 7 barriers that keep us from taking part in our communities, even when we truly care."
Vejam: tem a ver com o que se passa. Não é tudo, mas é uma parte.
