ActivityPub is a technical specification towards decentralized more precisely, federated social networking termed the Fediverse based upon the exchange of ActivityStreams messages that follow the Activity Vocabulary.
The ActivityPub proposal has been standardized and published by the W3C and has motivated the design of several federated social networking systems. Economic networks are the primary abstractions though which we can conceptualize the state condition and evolution of economic interactions. This simply reflects the fact that human economies are quite fundamentally systems of interacting actors or nodes in a network with transient or more permanent relations between them.

In this second Open Risk White Paper on Connecting the Dots we examine measures of concentration, diversity, inequality and sparsity in the context of economic systems represented as network graph structures. We adopt a stylized description of economies as property graphs and illustrate how relevant concepts can be represented in this language.
We explore in some detail data types representing economic network data and their statistical nature which is critical in their use in concentration analysis. We proceed to recast various known indexes drawn from distinct disciplines in a unified computational context. We adopt a stylized description of economies as property graphs and illustrate how relevant concepts can represent in this language.
As we move into February the world will be experiencing almost a year under pandemic conditions. This has markedly changed behavioral patterns of human mobility across the board. One major difference with previous pandemics is that through the use of a variety of digital technologies and new data collection channels we know have an unprecedented view of those changing mobility patterns. In previous posts here , and here we introduced new Open Risk Dashboard functionalities that integrate COVID community mobility data currently focusing on the datasets provided by Google.
