Performance study of Internet traffic on high speed railways
2013 IEEE 14th International Symposium on "A World of Wireless, Mobile and Multimedia Networks" (WoWMoM), 2013 Railway transportation uses specific technologies such as GSM-R for traffic signaling purposes, but commercial networks could also provide added value services to passengers and transport companies such as CCTV or telemetry. Furthermore mobile users increasingly want to be always connected even when they are traveling.

Membership‐Making in Diverse Societies: Revisiting the Idea of Society as a Common Possession
Journal of Applied Philosophy, EarlyView.ABSTRACT The traditional aim of Western social democracy has been to create a society that is a ‘common possession’ of its members (in T.H. Marshall's words). Social democratic politics has therefore been both society‐making and membership‐making, orienting people to a shared society as an object of attachment and loyalty, and nurturing membership ...

People and Nature, EarlyView.Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
