***** To join INSNA, visit http://www.insna.org ***** Dear Socnetters, Ever since I started Connections in 1977, I've been putting germane abstracts into it. Altho hard work (especially in the old days, when we had to retype everything), surveys showed it was our most popular feature. I've been sending abstracts to the editors of Connections weekly, but alas Connections seems to have disappeared. (Am I the only one who misses it?) So, starting NOW, I am going to put the abstracts online on Socnet, as well as sending them to the editors for (what I hope) will be their eventual appearance. I rely heavily on Complexity Digest, btw. Here's the first one: The Product Space Conditions the Development of Nations , Science Excerpts: Network analysis of the products made by rich and poor countries show that movement toward higher-profit products may be restricted for much of the developing world. Economies grow by upgrading the products they produce and export. The technology, capital, institutions, and skills needed to make newer products are more easily adapted from some products than from others. Here, we study this network of relatedness between products, or "product space," finding that more-sophisticated products are located in a densely connected core whereas less-sophisticated products occupy a less-connected periphery. *  The Product Space Conditions the Development of Nations, C. A. Hidalgo, B. Klinger, A.-L. Barab?si, R.
