ABSTRACTFor ten years CIBER has been studying the logs of scholarly publishers, and what was clear from the very beginning was that scholars conducted very brief visits to websites and spent very little time reading when there, yet publishers envisaged they would dwell; and if not dwell, then at least deep read the PDF later. Yet CIBER's research points to the fact that ‘lite’ reading is in fact endemic: younger people prefer it anyway and older people are getting used to it for the speed and convenience it brings. PDFs are largely a means of archiving and collecting and are not the gold standard reading metric people think. User satisfaction comes not from a PDF but from the ability to deep dive into a site and snatch what you are interested as quickly as possible. Publishers are still not comfortable with that and this article helps explain why they have to be.

Complementing macro-only cellular networks with low-powered base stations is a promising deployment solution to improve both network coverage and capacity, and cope with exploding data traffic in the coming years. In Beyond 3G Networks, such as LTE-Advanced, Relay Nodes and micro base stations can transmit on the same spectrum as the overlaying macro layer, and guarantee higher spatial reuse through cell splitting. Differently from previous research studies, this paper specifically aims at evaluating and comparing the potential of LTE relay and micro deployment in a realistic metropolitan scenario. A heuristic deployment algorithm which combines network coverage and realistic spatial user density information is also proposed. The results show that for the downlink, in-band relays can be deployed to improve network coverage, but not substantially the network capacity due to the limitation of the wireless backhaul link. In-band micro deployment, on the other hand, is the best solution to boost downlink network capacity (up to 5 times), while also providing full network coverage.
