A new Bayesian analysis of remote work data supports one the oldest theories in social networks, with fresh implications for future environments.

The goal of this lecture is to give an introduction to the state of the art in the theory of network communication. It is a widely accepted fact that algorithmic advances in the area of computer science are only useful to society if they are based on models that truthfully reflect the restrictions and requirements of the corresponding applications. This is certainly also true for network commun...

Actor network theory (ANT), also known as enrolment theory or the sociology of translation, emerged during the mid-1980s, primarily with the work of Bruno Latour, Michel Callon, and John Law. ANT is a conceptual frame for exploring collective sociotechnical processes, whose spokespersons have paid particular attention to science and technologic activity. Stemming from a Science and Technologies...

Actor-Network Theory (ANT) emerged from science and technology studies, though it was inspired by grounded theory and semiotics. In the 1970s, Bruno Latour (a French anthropologist and social scientist) and Steve Woolgar (a British sociologist) undertook ethnographic field work at the Salk Institute in California. This research was inspired by grounded theory and Latour and Woolgar approached t...

We employ concepts from graph theory and cooperative game theory to reconstruct Granovetter’s famous thesis concerning ‘the strength of weak ties’. In contrast to existing formal models related to this thesis, our approach captures the mechanisms Granovetter invokes in the derivation of his thesis. Notably, our model allows for an analytical distinction between the strength of ties and the valu...

This paper introduces a new trade model type. It combines the gravity model, well-known in international economics, with network theory. With this approach, complicated trade networks can be algebraically solved in form of systems of linear (differential) equations. Business cycles and productivity shocks can be represented via complex numbers or the Laplace transformation. With the help of thi...

this chapter I review empirical studies directly testing the hypotheses of m y 1973 paper " T h e Strength of Weak Ties" (hereafter "SWT") and work that elaborates those hypotheses theoretically or uses them to suggest new empirical research not discussed in my original formulation. Along the way, I will reconsider various aspects of the theoretical argument, attempt to plug some holes, and bro...

The high lever goal of the research activities in our groups is to extend the conventional information theory to develop theoretical tools that can be applied to a broader range of problems, including dynamic communications, networks, real-time communications, cooperative communications, etc. and even beyond the realm of communications, to understand the information exchange in algorithms, soci...
