The Danish Research Council has provided funding for a new international network, Research network for curatorial studies, (ca. 1 million dkr.) for a two-year period. The network is based at University of Copenhagen with principal leaders Malene Vest Hansen, Ph.D. in Art History, Department of Arts and Cultural Studies, and Anne Folke Henningsen, Ph.D. in History, the Saxo Institute. The following is a short introduction to the background for and the objectives of the network.

This chapter introduces the field of historical network research. Many historical outcomes of interest to social scientists are greatly affected by network processes. These include revolutions, segregation, increasing inequality, party polarization, market development, state centralization, and the rise and fall of institutions. The chapter considers the current state of historical network research across these and other outcomes by focusing on six different network phenomena: cross-cutting ties, informal social ties, associational and organizational networks, narrative networks, cohesion, and brokerage and centrality. Extant research has presented some contradictory findings about the relationoship of these findings to major social outomes, suggesting further specification is necessary. The goal of this chapter is to provide a synthesis that illuminates a pathway to maximize future contributions.

With the growing popularity of robots, the development of robot applications is subject to an ever increasing number of additional requirements from e.g., safety, legal and ethical sides. The certification of an application for compliance to such requirements is an essential step in the development of a robot program. However, at this point in time it must be ensured that the integrity of this program is preserved meaning that no intentional or unintentional modifications happen to the program until the robot executes it. Based on the abstraction of robot programs as workflows we present in this work a cryptography-powered distributed infrastructure for the preservation of robot workflows. A client composes a robot program and once it is accepted a separate entity provides a digital signature for the workflow and its parameters which can be verified by the robot before executing it. We demonstrate a real-world implementation of this infrastructure using a mobile manipulator and its software stack. We also provide an outlook on the integration of this work into our larger undertaking to provide a distributed ledger-based compliant robot application development environment.
