Cities of Knowledge and Big Science in Developing Countries: Luxury or Investment? The GCLSI Case

Claudio Pellegrini, Galileo Violini, Giorgio Margaritondo, Leonardo Lomel\'i-Vanegas, Vanessa Mej\'ia-Casco, V\'ictor M. Casta\~no

A Caribbean synchrotron is economically feasible for Latin America and would seed knowledge cities across the region.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

It is shown that an initiative of this sort is compatible with the economies of the region and would require a marginal increase of the current regional investment in science... the return of the investment would have its break-even point long before the end of the expected lifetime of the infrastructure, and that through a system of smaller accelerators... the benefit would not concentrate on the country hosting the facility.

C2weakest assumption

That the unstated economic models and development-impact projections used to reach the break-even and knowledge-city conclusions are accurate and that political and implementation barriers will not prevent the marginal increase in science spending.

C3one line summary

A regional synchrotron in Latin America is claimed to be affordable, to recover its costs before the end of its life, and to spread development benefits via distributed smaller facilities that nucleate knowledge cities.
