Visitor behaviour and public health implications associated with exotic pet markets: an observational study
OBJECTIVES To conduct on-site assessments of public health implications at key European pet markets. DESIGN Observational study of visitor behaviour at stalls that displayed and sold animals, mainly amphibians and reptiles, to assess potential contamination risk from zoonotic pathogens. We noted initial modes of contact as 'direct' (handling animals) as well as 'indirect' (touching presumed c...
متن کاملAn Analysis of Visitor Circulation:
How visitors circulate through museums determines what they will see, where they will focus their attention, and, ultimately, what they will learn and experience.

This article reviews the literature on visitor circulation in light of the general value principle which predicts choice behavior as a ratio of perceiv...

Here, we (1) describe the dispersal of this blood-feeding nematode, endemic to the Japanese eel (A. japonica), in Europe and North America...
متن کاملAn Exotic 4-manifold
In [1] we have constructed a fake smooth structure on a contractible 4-manifold W relative to boundary. This is a smooth manifold V with d V = d W such that the identity map d V —• d W extends to a homeomorphism but not to a difFeomorphism V -+ W. This is a relative result in the sense that V itself is diffeomorphic to W, even though no such diffeomorphism can extend the identity map on the bou...
