Polana amapaensis Coelho, 1991 has its ovipositor described and illustrated, based on the examination of the female paratype, from Amapá State, Brazil. This is the first detailed description of the female genitalia of a Polana DeLong, 1942 species. We compared the female genitalia of P. amapaensis with those of other Gyponini genera. Our results confirm that the female genitalia in this tribe c...

What do the rst concepts look like? I propose that the earliest concepts learned by infants are abstractions of activities. The semantics of these concepts are predictive|a good abstraction is one that will help the infant predict reward. This idea has been implemented in several programs, in particular, as uents in the Baby simulator and preimages in Coelho and Grupen's robotics work. Addition...

Extending the work of Fröhlich, Lue and Furtado-Coelho, we consider the theory of Baer invariants in the context of semi-abelian categories. Several exact sequences, relative to a subfunctor of the identity functor, are obtained. We consider a notion of commutator which, in the case of abelianization, corresponds to Smith’s. The resulting notion of centrality fits into Janelidze and Kelly’s the...
