Matheus, R. (author), Faber, R.M. (author), Ismagilova, Elvira (author), Janssen, M.F.W.H.A. (author)Open Government efforts are criticized for providing limited value. Instead of looking at a value, we investigate the usefulness of web-based open government portals and apps. Specifically, we investigated the relationship between digital transparency and usefulness. We analyzed perceived digital transparency and usefulness in a survey of 112...journal article 2023

(author), Kemps, Hareld M.C. (author), Evers, A.W.M. (author)The authors regret that the Standard Deviation (SD) for those who failed their challenge (n = 19,693) was erroneously reported in the Abstract (page 1) and Table 2 of the Results section (page 6) as 3013 steps. The correct Standard Deviation that should have been reported there is 2993 steps. Furthermore, in the Results section under header 3...journal article 2023

Ramadhan, M.G. (author), Janssen, M.F.W.H.A. (author), van der Voort, H.G. (author)Internal audit function (IAF) effectiveness can be improved by embracing Audit Analytics (AA). However, despite its promises, AA implementation remains limited. Although there is research on AA implementation in general, there needs to be an overview of insight into inhibiting and driving factors for internal auditing. This paper examines those...journal article 2023

Governance impacts of blockchain-based decentralized autonomous organizations: An empirical analysisRikken, O.K. (author), Janssen, M.F.W.H.A. (author), Roosenboom-Kwee, Z. (author)The rapid rise in blockchain-based Decentralized Autonomous Organizations (DAOs) offers policy-makers and decision-makers new opportunities to automatically execute decisions and processes that help enhance transparency, accountability, participation and trust. Yet, many DAOs have a limited lifespan. There is little empirical evidence of the...journal article 2023

Paulus, D. (author), de Vries, G. (author), Janssen, M.F.W.H.A. (author), Van de Walle, Bartel (author)A crisis requires the affected population, governments or non-profit organizations, as well as crisis experts, to make urgent and sometimes life-critical decisions. With the urgency and uncertainty they create, crises are particularly amenable to inducing cognitive biases that influence decisionmaking. However, there is limited empirical...journal article 2022

van Iersel, L.J.J. (author), Janssen, R. (author), Jones, M.E.L. (author), Murakami, Yukihiro (author), Zeh, Norbert (author)We present the first fixed-parameter algorithm for constructing a tree-child phylogenetic network that displays an arbitrary number of binary input trees and has the minimum number of reticulations among all such networks. The algorithm uses the recently introduced framework of cherry picking sequences and runs in O((8 k) <sup>k</sup>poly (n,...journal article 2022

van Iersel, L.J.J. (author), Janssen, R. (author), Jones, M.E.L. (author), Murakami, Yukihiro (author)Phylogenetic networks are used in biology to represent evolutionary histories. The class of orchard phylogenetic networks was recently introduced for their computational benefits, without any biological justification. Here, we show that orchard networks can be interpreted as trees with additional horizontal arcs. Therefore, they are closely...journal article 2022

Janssen, C. (author), Basta, Claudia (author)Social sustainability is a multidimensional concept sensitive to the contexts of its application. This study explores how it is interpreted and applied in urban planning practices in which general social sustainability goals are translated into specific urban design interventions. Building upon Sen’s Capability Approach (CA), we analyse the gap...journal article 2022

(author)Fraud analytics refers to the use of advanced analytics (data mining, big data analysis, or artificial intelligence) to detect fraud. While fraud analytics offers the promise of more efficiency in fighting fraud, it also raises legal challenges related to data protection and administrative law. These legal requirements are well documented but...journal article 2022

Kazaz, T. (author), Janssen, G.J.M. (author), Romme, J.P.A. (author), van der Veen, A.J. (author)In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have...journal article 2022

Although XAI is appealing as a solution for automated decisions, the wicked nature of the challenges governments face complicates the use of XAI. Wickedness means that the facts that define...journal article 2022
