Show moreThis paper empirically explores the contribution and collaborative networks of public and private actors to cybersecurity provision in Spain. The article draws on data from three sources: policy and legal documents, a Delphi study with cybersecurity experts, and 34 interviews. Rooted in the theoretical underpinnings of nodal governance and anchored pluralism, the paper argues that the position of actors and public-private collaboration dynamics involved in cybersecurity governance can be understood through the analysis of capital exchange. Therefore, the study provides a list of the most relevant nodes for cybersecurity in Spain, assesses the capital they possess and how they exchange it through collaborative networks and explores the characteristics and barriers of these collaborative relationships. Analyses reveal that public organisations hold a preeminent position in cybersecurity governance despite large technology corporations’ greater economic and cultural capital. Remarkably, the paper identifies the central position of new public bodies in the network of cybersecurity nodes. Moreover, cultural barriers that are hindering public-private collaboration in Spain are identified. These results indicate that, despite the state’s difficulties in providing public solutions to cybersecurity challenges, Spain is an example of how governance can be anchored in public bodies through symbolic and social capital.

Show moreHow do we make sure that all citizens in a city have access to enough green space? An increasing part of the world’s population lives in urban areas, where contact with nature is largely reduced to street trees and parks. As optional tree planting sites and financial resources are limited, determining the best planting site can be formulated as an optimization problem with constraints. Can we locate these sites based on the popularity of nearby venues? How can we ensure that we include groups of people who tend to spend time in tree deprived areas?Currently, tree location sites are chosen based on criteria from spatial-visual, physical and biological, and functional categories. As these criteria do not give any insights into which citizens are benefiting from the tree placement, we propose new data-driven tree planting policies that take socio-cultural aspects as represented by the citizens’ behavior into account. We combine a Location Based Social Network (LBSN) mobility data set with tree location data sets, both of New York City and Paris, as a case study. The effect of four different policies is evaluated on simulated movement data and assessed on the average, overall exposure to trees as well as on how much inequality in tree exposure is mitigated.

Show moreThis article, written for a wide audience in Dutch, provides a summary of the author's PhD dissertation, Episcopal Networks and Authority in Late Antique Egypt (defended in November 2017, published by Peeters in Leuven in 2018), on seventh-century bishops who represented a new church hierarchy and were organizing it on a local level. This hierarchy is the forerunner of the present-day Coptic Orthodox Church. Show less

Previously, it was assumed that the bishop died between ca. 610 and 620, but the author argues that he passed away in 621. Show less
