Recent evidence indicates profound changes in population mobility in the Amazon frontier. Following the earlier large-scale migration influxes from long-settled regions, the most dramatic forms of population mobility under way are currently within the frontier. In particular, more and more rural households see temporary or permanent mobility of one or more family members to urban areas as a way...

"The aim of this paper is to argue the importance of considering ¿the household' in analyses of gender and rural-urban migration, both in respect of how it shapes the gender selectivity of migrant flows and how, in turn, the latter contributes to household diversity across rural and urban areas.... [It] examines the impacts of gender differentiated demographic mobility on contemporary household...

Abstract Maximizing the functional performance of urban green infrastructure is important to deliver critical ecosystem services that support human well-being. However, ecosystems are impacted by social and ecological filters affect biodiversity, shaping how species’ traits functionally expressed, thus affecting supply. Our Social–Ecological Traits Framework addresses impacts socio-ecological s...

The combined effects of global warming, urbanization, and demographic change influence climate risk for urban populations, particularly in metropolitan areas with developing economies. To inform adaptation spatial planning, it is important to study climatic hazards populations at relation growth trends development patterns. However, this relationship has not been adequately investigated studies...

The complete classification of hexapods — also known as Stewart Gough platforms — of mobility one is still open. To tackle this problem, we can associate to each hexapod of mobility one an algebraic curve, called the configuration curve. In this paper we establish an upper bound for the degree of this curve, assuming the hexapod is general enough. Moreover, we provide a construction of hexapods...

Mechanical linkages are used to transmit and transform motion. In this paper we investigate what it might mean to "understand" a linkage, i.e. how one would explain the functioning of the system. We present a system capable of understanding a variety of relatively simple linkage mechanisms found in standard references. Our system extracts its understanding by analyzing the results of a numerica...
