AbstractEcho chambers in online social networks, in which users prefer to interact only with ideologically-aligned peers, are believed to facilitate misinformation spreading and contribute to radicalize political discourse. In this paper, we gauge the effects of echo chambers in information spreading phenomena over political communication networks. Mining 12 million Twitter messages, we reconstruct a network in which users interchange opinions related to the impeachment of the former Brazilian President Dilma Rousseff. We define a continuous political leaning parameter, independent of the network’s structure, that allows to quantify the presence of echo chambers in the strongly connected component of the network. These are reflected in two well-separated communities of similar sizes with opposite views of the impeachment process. By means of simple spreading models, we show that the capability of users in propagating the content they produce, measured by the associated spreading capacity, strongly depends on their attitude. Users expressing pro-impeachment leanings are capable to transmit information, on average, to a larger audience than users expressing anti-impeachment leanings. Furthermore, the users’ spreading capacity is correlated to the diversity, in terms of political position, of the audience reached. Our method can be exploited to identify the presence of echo chambers and their effects across different contexts and shed light upon the mechanisms allowing to break echo chambers.

The Village

Bumdes is a village business unit whose capital comes from village-owned funds . The goal is to float the village potential into an independent village. Thus it takes effort and strategic and appropriate tips to achieve that goal. The first tip is to establish a forum for the development of economic networks in this case is the establishment of BUMDES. Some of the things that can be done are: (i) development of human resources capability so as to provide added value in the management of village economic assets, (ii) integrating rural economic products so as to have good bargaining position in market network, (iii) (iv) strengthening village economic institutions, (v) developing supporting elements such as micro-credit, market information, technological and management support, economic infrastructure and communication networks as well as support for guidance and regulation.
