Desde la perspectiva sociológica, el concepto de tecnología no puede referirse únicamente a los objetos técnicos, sino también a los procesos sociales y culturales que involucra. La sociocibernética y la teoría de sistemas plantean un marco conceptual esencial para el necesario debate sobre el papel de la tecnología en la configuración de la complejidad social. La tecnología permite al sistema social gestionar la complejidad social. La tecnología permite al sistema social gestionar la complejidad de su entorno a la vez que, por otra parte, contribuye a incrementar y diversificar la naturaleza compleja de las interdependencias entre la sociedad y los actores individuales. Simultáneamente, la creciente complejidad social demanda nuevas formas tecnológicas que permitan gestionarla. En suma, la tecnología se halla en la base de cualquier discusión relevante sobre la naturaleza contemporánea de la sociedad, ya sea del lado de los problemas (riesgo, control, y vigilancia global, bioética y bioingeniería, manipulación mediática, ecológica etc.) o del lado de las soluciones (comunicaciones instantáneas, ubicuidad y movilidad, accesibilidad, disponibilidad de conocimiento, etc.).

Les espècies evolucionen, canvien amb el pas del temps i així ho va constatar i argumentar Charles Darwin. El que té entre les mans és una obra que intenta integrar dues grans visions de l?evolució que sovint es presenten enfrontades. D?una banda, la visió que emfatitza la contingència, els accidents congelats i la irreversibilitat, i determina una ciència eminentment històrica. De l?altra, la visió més racio¬nal, basada en la comprensió dels processos d?auto¬organització semblants als d?altres sistemes físics allunyats de l?equilibri termodinàmic, i que determina una ciència estructuralista. El resultat és una visió més rica i plural del fenomen evolutiu, en la qual es posen en evidència els paradigmes clàssics. Una revisió acurada de la visió més ortodoxa de l?evolució a la recerca d?explicacions teòriques que van més enllà dels límits de la biologia.

Over this last decade, the concept of Social Metabolism has gained prestige as a theoretical instrument for the required analysis, to such an extent that there are now dozens of researchers, hundreds of articles and several books that have adopted and use this concept. However, there is a great deal of variety in terms of definitions and interpretations, as well as different methodologies around this concept, which prevents the consolidation of a unified field of new knowledge. The fundamental aim of the book is to conduct a review of the past and present usage of the concept of social metabolism, its origins and history, as well as the main currents or schools that exist around this concept. At the same time, the reviews and discussions included are used by the authors as starting points to draw conclusions and propose a theory of socio-ecological transformations. The theoretical and methodological innovations of this book include a distinction of two types of metabolic processes: tangible and intangible; the analysis of the social metabolism at different scales (in space and time) and a theory of socio-ecological change overcoming the merely “systemic” or “cybernetic” nature of conventional approaches, giving special protagonism to collective action.

This book is about dynamical, social-interactional aspects of the emergence of complexity in language, explained by linguists, cognitivists, and modelers.

This book offers insights on the study of natural language as a complex adaptive system. It discusses a new way to tackle the problem of language modeling, and provides clues on how the close relation between natural language and some biological structures can be very fruitful for science. The book examines the theoretical framework and then applies its main principles to various areas of linguistics. It discusses applications in language contact, language change, diachronic linguistics, and the potential enhancement of classical approaches to historical linguistics by means of new methodologies used in physics, biology, and agent systems theory. It shows how studying language evolution and change using computational simulations enables to integrate social structures in the evolution of language, and how this can give rise to a new way to approach sociolinguistics. Finally, it explores applications for discourse analysis, semantics and cognition.

This book aims to contribute to the overall, integrated understanding of the processes of language contact and their evolution, be they the result of political or economic (dis)integrations or migrations or for technological reasons. Via an interdisciplinary, holistic approach, it also aims to support the theoretical grounding of a unified, common sociolinguistic paradigm, based on an ecological and complexity perspective. This approach built on the fact that linguistic structures do not live in isolation from their social functions and must be situated in relation to the sub-and supra-systems that determine their existence if we are to understand their fortunes. It is a useful contribution to understanding and promoting the processes of linguistic revitalization in the world, combining at the same time the maintenance and development of diversity while ensuring the intercommunication of human species.
