Budget visualization tools facilitate the communication of complex technical information. In this paper, we analyse the main technical, individual and organizational factors that affect its implementation and use. Through a questionnaire survey we have collected data from those responsible for the web application "Dónde van mis impuestos" ("Where do my taxes go?") in 23 Spanish regional and local governments. Our findings show that these tools have a small number of users but that their main target are not citizens but specific groups, mainly media and political groups. Its adoption is neither a budgetary nor technological problem, although the free software license gives clear advantages. The impulse for adoption is mainly political with the main focus on financial and budgetary transparency but sometimes also on participatory transparency or microtransparency. Finally, we detect a serious risk of governance generated by the lack of clear transparency and accountability strategies in the administrations, as well as an absence of operational procedures to adapt to the changing budgetary structure.

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. All knowledge's community show several characteristics in common: granularity, hospitality, mediation and an activist component to achieve a goal. Both analyzed communities share similar ethos.

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.

Configuration management in a data networks requires the proper use of procedures and tools to improve administrator efficacy and users satisfaction. This paper presents main problems around that kind of network management and the application of policy based network management concepts to those problems solutions. This work introduces a system for user-level service configuration management based on open source software and one example of its application. [ABSTRACT FROM AUTHOR]
