The purpose of this paper is to identify trends in research at a global level in the supply chain of the Integral and Sustainable Management of Solid Waste (ISMSW), in terms of management and treatment of Municipal Solid Waste (MSW). For this purpose, an exhaustive search of articles in specialized databases was carried out, information that was processed using the free software applications Bibexcel, Pajek, VoSviewer © and Tagxedo for bibliometric analysis. As a result, it was found a predominant use of technologies to treat MSW for the purpose of energy recovery. On the other hand, the ISMSW analyzed as a supply chain, involves SWM treatment decisions, actors involved and environmental, technical, social and economic aspects. Finally, four major research gaps or opportunities were identified that can be addressed with engineering tools to support decisions that involve resources, money and energy flows.

This paper tries to analyze communities of knowldege such as the communities of public domain software and the open knowledge.

Final claim asserts that this new actors generate a kidnapping of the activist objectives of this communities. [ABSTRACT FROM AUTHOR]

This paper describes a systemic analysis from the standpoint of activity theory of the cultural emergence of a virtual learning community as a complex system. Three levels of analysis were employed: data mining, visualization of complex systems and analysis of discursive interactions, with the aim of understanding the emerging phenomena of online learning and in order to have the necessary elements to assist in planning the formation of virtual communities in formal settings. This was carried out using six years of activity from 3,324 people from different documentary sources: 9,871,531 CMS records; 1,371,907 from LMS; 67,828 IRC statements; and 27,798 online forum comments. In the process, we observed how action aimed at socialization and discussion of its object evolve into historical-cultural milestones such as the culture of merit as opposed to certification, the division of labor and the process of transition from free software to free culture.
