  In what ways are human cognitive skills growing faster than Moore's Law?

  Some believe that chip density/speed growth shows rapid development of computers, but human knowledge and skills are also growing rapidly on a global basis.

    First we need to understand "sleep". During REm for instance hypocampus is active, playing the song of the day to the cortical region. Dreaming is associated to this kind of "sleep". In deep sleepFirst we need to understand "sleep". During REm for instance hypocampus is active, playing the song of the day to the cortical region. Dreaming is associated to this kind of "sleep". In deep sleep what happens? When in Meditation (and its several stages) aren´t we simulating day sleeping? Brain tomography can answer these questions?

    a recent post from another egonet group: Some help required analyzing ego-network data in UCINET: I have 88 ego-networks, with a total of 606 alters.

To start with, I am using UCINET to gather some basic measures of the ego-networks to allow me to compare them – measures such as density, geodesic distance etc etc. So far, and this is my first social network data analysis experience, I have been using UCINET point and click method (network->cohesion->blah) – which, as you can imagine, becomes rather tedious after only 10 or so ego networks have been analysed for ONE of the many measures that are possible. So, are there shortcuts? Can I paste all my data into one spreadsheet separated into 88 groups and run one measure at a time using that? Or, can I gather more than one measure at a time for each network ( a bit like: network->centrality->multiple measures)? Or something completely different? Or, should I use something other than UCINET? Thanks in advance of any help, Carl
