This paper brings together the perceptions of three youths from Barrio San Jorge, a low-income settlement located in the municipality of San Fernando in the Buenos Aires Metropolitan Area, and the more technical views of three adult researchers working in the same barrio with the Instituto Internacional de Medio Ambiente y Desarrollo—América Latina (IIED—AL). It highlights youth’s perceptions and aspirations within a context of neighbourhood upgrading and transformation, and discusses some ideas on how best to approach and work with youth, addressing the challenges of integration, participation and commitment.

Abstract. This paper describes a tissue P system for solving the Shortest Common Superstring Problem in linear time. This tissue P system is well suited for parallel and distributed implementation using a microfluidic device working with DNA strands. The tP system is not based on the usual brute force generate/test technique applied in DNA computing, but builds the space solution gradually. The possible solutions/superstrings are build step by step through the parallel distributed combination of strings using the overlapping concatenation operation. Moreover, the DNA microfluidic device solves the problem autonomously, without the need of external control or manipulation.
