In a cell or microorganism the processes that generate mass, energy, information transfer, and cell fate specification are seamlessly integrated through a complex network of various cellular constituents and reactions. However, despite the key role these networks play in sustaining various cellular

Serious concerns have been raised about the ecological effects of industrialized fishing Ecological communities on continental shelves and in the open ocean contribute almost half of the planet's primary production 9 , and sustain three-quarters of global fishery yields 1 . The widespread

The initial investigation has outlined two sets of highlevel factors that may be used when choosing formats: • conceptual factors that may affect the sustainability of any digital format • factors that relate to quality or special functionality that might be desired for certain categories of content

Abstract. The impact of Collaborative Virtual Environments (CVEs) on communities ’ development is a topic still rather unexplored. All the interaction processes mediated by these technological environments are characterised, from both psychosocial and discursive points of view, by absolutely new practices and by the absence of some communication features, typical of face-to face. The “Community of Practice ” model, allows us to analyse the growth of virtual communities along the construction of a shared repertoire, the involvement in a common enterprise and the sharing of a mutual engagement. Communities of practice use technology in social and material contexts, sharing meanings about the technology uses and peculiarities through a continuous negotiating process. The analysis is aimed at describing how a community of practice is established in a virtual world where both textual and graphical interactions are allowed. Conversational and quantitative results show: a) how the community of practice evolves over the time, b) the specificity of the interactions mediated by the virtual environment; c) the role of different participants in the management of discourse in interaction, with a detailed analysis of the on-line tutorship impact on the development of the community.

Abstract: Over a 25 year span, using five year increments, the index of sustainable functionality (ISF) was applied to measure sustainability within the region of South East Queensland (SEQ), Australia. This study uses functionality by relating it to the level of sustainability within the measured

Abstract—Several analytic models describe the steady-state throughput of bulk transfer TCP flows as a function of round trip time and packet loss rate. These models describe flows based on the assumption that they are long enough to sustain many packet losses. However, most TCP transfers across

. In particular, using the theoretical model of Tanaka(2004) I demonstrate that a financial function of SRI can prompt sustainable environmental management effectively.
