Las investigaciones arqueológicas desarrolladas en el sitio Cueva de Plaza permitieron reconocer el primer contexto funerario indígena datado en momentos históricos para el valle del Genoa (Chubut, Argentina). En este sitio se registraron restos óseos humanos, materiales faunísticos, artefactos líticos, cuentas vítreas, fragmentos de cuero y restos vegetales. Se presenta el sitio y se da a conocer el análisis tafonómico, bioarqueológico y paleopatológico de las muestras humanas, además de otras líneas de evidencia. En la cueva se detectó la acción de diversos agentes que generaron el desplazamiento y la mezcla de los materiales arqueológicos. Se realizaron dos dataciones radiocarbónicas que, sumadas a la presencia de cuentas de vidrio de tipo venecianas, permitieron determinar que al menos algunas de las actividades funerarias se desarrollaron entre los siglos XVIII y XIX. Las características de este contexto se discuten en el marco general de las prácticas mortuorias contemporáneas de los cazadores-recolectores del centro-oeste de Chubut.
Abstract.The new generation of web-based communities, Web. 2.0, represents an innovation in terms of users interaction as it becomes increasingly dependent of it. It empowers users to create and manage content, placing them at the core of its success. This paper will propose a Web 2.0 Critical Success Factors (CSFs) theoretical framework. With the widespread popularity of these applications it becomes important to analyze the source of their success and unveil why some are more successful than others. More importantly, it may help Web 2.0 start-ups to understand what features they need to develop to make their applications succeed in an already very populated network.
Aim/PurposeAs e-Learning 3.0 evolves from a theoretical construct into an actual solution for online learning, it becomes crucial to accompany this progress by scrutinising the elements that are at the origin of its success. Background This paper outlines a framework of e-Learning 3.0's critical success factors and its empirical validation.
MethodologyThe framework is the result of an extensive literature review and its empirical substantiation derives from semi-structured interviews with e-Learning experts.
ContributionThe viewpoints of the experts enable the confirmation and the refinement of the original framework and serve as a foundation for the prospective implementation of e-Learning 3.0.
FindingsThe analysis of the interviews demonstrates that e-Learning 3.0 remains in its early stages with a reticent dissemination. Nonetheless, the interviewees invoked factors related to technology, content and stakeholders as being critical for the success of this new phase of e-Learning.
Recommendations for PractitionersPractitioners can use the framework as a guide for promoting and implementing effective e-Learning 3.0 initiatives.

Recommendation for ResearchersAs a new phenomenon with uncharted potential, e-Learning 3.0 should be placed at the centre of educational research. Impact on Society The understanding of what drives the success of e-Learning 3.0 is fundamental for its implementation and for the progress of online education in this new stage of its evolution.
Future ResearchFuture research ventures can include the design of quantitative and selfadministered data collection instruments that can provide further insight into the elements of the framework.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
