Revisiting digital technologies: envisioning biodigital bodies
In this paper the contemporary practices of human genomics in the 21st century are placed alongside the digital bodies of the 1990s. The primary aim is to provide a trajectory of the biodigital as follows: First, digital bodies and biodigital bodies were both part of the spectacular imaginaries of early cybercultures. Second, these spectacular digital bodies were supplemented in the mid-1990s by digital bodywork practices that have become an important dimension of everyday communication. Third, the spectacle of biodigital bodies is in the process of being supplemented by biodigital bodywork practices, through personal or direct-to-consumer genomics. This shift moves a form of biodigital communication into the everyday. Finally, what can be learned from putting the trajectories of digital and biodigital bodies together is that the degree of this communicative shift may be obscured through the doubled attachment of personal genomics to everyday digital culture and high-tech spectacle.Keywords: genomics, biodigital, bodies, spectacle, everyda
Quasi-Isometry Invariance of Group Splittings over Coarse Poincar\'e Duality Groups
We show that if is a group of type that is
coarsely separated into three essential, coarse disjoint, coarse complementary
components by a coarse space then is at finite
Hausdorff distance from a subgroup of ; moreover, splits over a
subgroup commensurable to a subgroup of . We use this to deduce that
splittings of the form , where is of type
and is a coarse group such
that both and are greater
than two, are invariant under quasi-isometry.Comment: 46 page
