The written word has long been a revolutionary agent: manifestos can change the course of history and topple governments. When the rebels take to the streets, they head first to the newspapers and the radio stations, only later to the presidential palace. Once, dissidents cranked out their discontent on basement mimeograph machines. Today they use Twitter.

As meandering rivers migrate laterally through their floodplains, the growth of individual bends increases the overall length and sinuosity of the channel. Intermittently, meander limbs from different bends migrate into one another causing the river pathway to shorten, in a process termed neck cutoff.

As vacancy in Rust Belt cities becomes a focal point of urban planning and policy, Chicago planners attribute vacancy to abandonment by capital and pursue a two-pronged development strategy that, on one front, seeks ways to efficiently revalorize land and, on another, casts vacancy as an opportunity to promote equitable redevelopment through resident-led revitalization.
-
Today, center-east areas in the city of Buenos Aires, especially the highly stigmatized villas (slums), seem ripe for a new phase of urban restructuring. Long-time residents of the villas, neglected for decades by public funds, now face “urbanization” processes, a euphemism neoliberal governance uses when transferring public urban land to the private market.

Confluences are recognized as locations within rivers where interaction between incoming flows produces complex hydrodynamic conditions characterized by distinct spatial patterns of mean or turbulent flow. Despite recognition of this hydrodynamic complexity, few studies have mapped in detail spatial patterns of flow at confluences and variation in these patterns over time.

As with cryosphere-dominated streams the world over, Alpine glaciers are retreating rapidly. As a glacier retreats progressively, it effectively switches on phototrophic activity. It is therefore not surprising that, for almost 100 years, the process has been construed as a chronosequence; one that, if vaguely, is even referred to in Charles Darwin’s Origin of the Species.
