Special issue in EHB: The Evolutionary Foundations of Magic, Witchcraft, Myth, and Taboo sciencedirect.com/special-issue/… All-star cast that includes anthropologists, psychologists, economists, philosophers and others. Great Editors: @aiyanakoka @KevinHong1991. Excellent work!

Siamo in una fase sociale gassosa. Ho cercato di portare qualche spunto sociologico sul dibattito su #giovani #proteste #Milano oggi su @La7tv @ignotox_

Si parla di #giovani e #protesta a #Milano. La #politica è più una parte del problema del disagio che non una soluzione. Trascrizione dell'intervista alla Radio della Svizzera Italiana di ieri rsi.ch/info/mondo/Pro…
