Matheus, R. (author), Janssen, M.F.W.H.A. (author)The opening of data has been credited for improving transparency and for providing a window on government functioning. Although this relationship is intuitively apparent, it is in fact complex and the mere opening of data might not actually yield transparency. In this paper, a comprehensive model of determinants that enable or impede...journal article 2019

Pirannejad, A. (author), Janssen, M.F.W.H.A. (author), Rezaei, J. (author)Since 2003, the United Nations has introduced the E-Participation Index (EPI), the first index to evaluate e-participation initiatives worldwide. This index has been subject to criticism for not representing the society side of e-participation initiatives. The EPI assesses e-participation initiatives on the government side only and neglects...journal article 2019

Hichert, M. (author), Abbink, D.A. (author), Vardy, A.N. (author), van der Sluis, Corry K. (author), Janssen, Wim G.M. (author), Brouwers, Michael A.H. (author), Plettenburg, D.H. (author)Operating a body-powered prosthesis can be painful and tiring due to high cable operation forces, illustrating that low cable operation forces are a desirable design property for body-powered prostheses. However, lower operation forces might negatively affect controllability and force perception, which is plausible but not known. This study...journal article 2019

Janssen, R. (author), Jones, M.E.L. (author), Kelk, Steven (author), Stamoulis, Georgios (author), Wu, Taoyang (author)Phylogenetic trees and networks are leaf-labelled graphs used to model evolution. Display graphs are created by identifying common leaf labels in two or more phylogenetic trees or networks. The treewidth of such graphs is bounded as a function of many common dissimilarity measures between phylogenetic trees and this has been leveraged in fixed...journal article 2019

Janssen, H.J. (author), Oberwittler, Dietrich (author), Gerstner, Dominik (author)Although urban disorder has played a central role in neighborhood research, its impact may have been overstated in studies relying on the subjective perception of survey respondents only. Research on the “perception bias”—defined as the divergence between respondents’ subjective assessments and systematic observations of disorder—has revealed...journal article 2019

Knol, Arthur (author), Sharpanskykh, Alexei (author), Janssen, S.A.M. (author)Modern airports operate under high demands and pressures, and strive to satisfy many diverse, interrelated, sometimes conflicting performance goals. Airport performance areas, such as security, safety, and efficiency are usually studied separately from each other. However, operational decisions made by airport managers often impact several...journal article 2019

Gong, Y. (author), Janssen, M.F.W.H.A. (author)Enterprise Architecture (EA) has been embraced by many organizations to improve the value of their IT. Our systematic literature review (SLR) reveals that EA is a broad concept that is interpreted and used in many different ways. This breadth can be explained by the various starting points taken, and by the content-dependent nature of many EA...journal article 2019

Janssen, Mariska M.H.P. (author), Harlaar, J. (author), Koopman, Bart (author), de Groot, Imelda J.M. (author)This study aimed to identify critical physiological outcome variables underlying reduced upper extremity task performance in Duchenne muscular dystrophy (DMD). These critical variables were used to propose an explanatory biophysical model of the upper extremity working mechanisms in DMD. Twenty-three DMD patients (8–21 years) participated in...journal article 2019

Janssen, H.J. (author), van Ham, M. (author), Kleinepier, T. (author), Nieuwenhuis, J.G. (author)Existing empirical research on the link between ethnic minority concentration in residential environments and voting for the radical right is inconclusive, mainly due to major differences between studies in the spatial scale at which minority concentration is measured. We examined whether the presence of non-western ethnic minorities in the...journal article 2019

Bronkhorst, Jeroen (author), Schaveling, Jaap (author), Janssen, M.F.W.H.A. (author)Based on a survey (N = 248 business managers) this study confirms that different types of innovation in IT products have a direct positive impact on IT firms’ business performance. The commoditization level of IT markets acts as a moderator dampening this positive relationship. This implies that IT firms should take existing commoditization...journal article 2019

Grover, Purva (author), Kar, Arpan Kumar (author), Janssen, M.F.W.H.A. (author), Ilavarasan, P. Vigneswara (author)Although blockchain has attracted a great deal of attention from academia and industry there is a lack of studies on acceptance drivers. This study explores blockchain acceptance by mining the collective intelligence of users on Twitter. It maps blockchain user acceptance drivers to technology acceptance constructs. The analysis shows that...journal article 2019

Janssen, M.T.G. (author), Pilus, Rashidah M. (author), Zitha, P.L.J. (author)A laboratory study of principal immiscible gas flooding schemes is reported. Very well-controlled experiments on continuous gas injection, water-alternating-gas (WAG) and alkaline–surfactant–foam (ASF) flooding were conducted. The merits of WAG and ASF compared to continuous gas injection were examined. The impact of ultra-low oil–water (o/w)...journal article 2019

Luthfi, A. (author), Janssen, M.F.W.H.A. (author)Over the last decade, more and more data are collected and opened. Governments actively stimulate the opening of data to increase citizen engagement to support policy-making processes. Evidence-based policy-making is the situation whereby decisions made are based on factual data. The common expectation is that releasing data will result in...journal article 2019

Olivares-Pulido, G. (author), Terkildsen, M. (author), Arsov, K. (author), Teunissen, P.J.G. (author), Khodabandeh, A. (author), Janssen, V. (author)Successful implementation of integer ambiguity resolution enabled precise point positioning (aka PPP-RTK) algorithms is inextricably linked to the ability of a user to perform near real-time positioning by quickly and reliably resolving the integer carrier-phase ambiguities. In the PPP-RTK technique, a major barrier to successful ambiguity...journal article 2019

(author)Graphene's maximized surface-to-volume ratio, high conductance, mechanical strength, and flexibility make it a promising nanomaterial. However, large-scale graphene production is typically cost-intensive. This manuscript describes a microbial reduction approach for producing graphene that utilizes the bacterium Shewanella oneidensis in...journal article 2019

Murakami, Yukihiro (author), van Iersel, L.J.J. (author), Janssen, R. (author), Jones, M.E.L. (author), Moulton, V.L. (author)Network reconstruction lies at the heart of phylogenetic research. Two well-studied classes of phylogenetic networks include tree-child networks and level-k networks. In a tree-child network, every non-leaf node has a child that is a tree node or a leaf. In a level-k network, the maximum number of reticulations contained in a biconnected...journal article 2019

(author)We developed an impedance bridge that operates at cryogenic temperatures (down to 60 mK) and in perpendicular magnetic fields up to at least 12 T. This is achieved by mounting a GaAs HEMT amplifier perpendicular to a printed circuit board containing the device under test and thereby parallel to the magnetic field. The measured amplitude and...journal article 2019
