Modelling cholera epidemics: the role of waterways, human mobility and sanitation

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, Marino Gatto

We investigate the role of human mobility as a driver for long-range spreading of cholera infections, which primarily propagate through hydrologically controlled ecological corridors. Our aim is to build a spatially explicit model of a disease epidemic, wh ...

Implications of in situ calcification for photosynthesis in a similar to 3.3 Ga-old microbial biofilm from the Barberton greenstone belt, South Africa

Anders Meibom, François Robert

Timing the appearance of photosynthetic microorganisms is crucial to understanding the evolution of life on Earth. The ability of the biosphere to use sunlight as a source of energy (photoautotrophy) would have been essential for increasing biomass and for ...

Stochastic dynamics of cholera epidemics

Andrea Rinaldo, Enrico Bertuzzo, Amos Maritan

We describe the predictions of an analytically tractable stochastic model for cholera epidemics following a single initial outbreak. The exact model relies on a set of assumptions that may restrict the generality of the approach and yet provides a realm of ...

Scientific diasporas from developing countries in Switzerland: empirical evidence and policy responses. Skilled migrants from Colombia, India and South Africa in Switzerland as partners in development

Jean-Claude Bolay, Gabriela Tejada Guerrero

Over the last two decades, globalisation has accelerated international migration flows, particularly of skilled labour. Yet increasing migration by skilled workers from developing countries («brain drain») has raised serious concerns internationally about ...

Ségrégation de l'espace. Quel avenir pour le township sud-africain: bidonville ou ville bidon (Mamelodi, Pretoria, Afrique du Sud)?

Sophie Greiller

Aujourd'hui, l'Afrique du Sud est à un tournant de son histoire car si la politique de ségrégation de l'espace a enfanté un urbanisme planifié, la réalité des quartiers informels qui prolifèrent en périphérie ( et désormais à l'intérieur même de la ville) ...

Sustainable Liquid Biofuels for Transport: The Context of the Southern Africa Development Community (SADC)

Edgard Gnansounou, Luis Alberto Panichelli, Juan David Villegas Gomez

The Southern African Development Community (SADC) has evolved in 1992 from the former Southern African Development Coordination Conference (SADCC) existing since 1980. The SADC aims at regional integration, sustainable growth and alleviation of poverty in ...

Multimodel ensemble simulations of tropospheric NO2 compared with GOME retrievals for the year 2000

Isabelle Bey, Jérôme Drevet

We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment (GOME) for the year 2000. The models used constant anthropogenic emissions ...
