van Calcar, C.J. (author), van de Wal, Roderik S W (author), Blank, B. (author), de Boer, Bas (author), van der Wal, W. (author)Glacial isostatic adjustment (GIA) has a stabilizing effect on the evolution of the Antarctic ice sheet by reducing the grounding line migration following ice melt. The timescale and strength of this feedback depends on the spatially varying viscosity of the Earth's mantle. Most studies assume a relatively long and laterally homogenous...journal article 2023

Nield, Grace A. (author), King, A. Matt (author), Steffen, Rebekka (author), Blank, B. (author)We present a finite-element model of post-seismic solid Earth deformation built in the software package Abaqus (version 2018). The model is global and spherical, includes self-gravitation and is built for the purpose of calculating post-seismic deformation in the far field (1/4300gkm) of major earthquakes. An earthquake is simulated by...journal article 2022

van Calcar, C.J. (author), de Boer, Bas (author), Blank, B. (author), van de Wal, Roderik S W (author), van der Wal, W. (author)The Earth’s surface and interior deform due to a changing load of the Antarctic Ice Sheet (AIS) during the last glacial cycle, called Glacial Isostatic Adjustment (GIA). This deformation changes the surface height of the ice sheet and indirectly the groundling line position. These changes in surface height and grounding line position influence...abstract 2021

Blank, J.L.T. (author)Building operations and construction are responsible for a large part of global energy use and carbon dioxide emissions. In this paper, we present an analysis of the efficiency and productivity of the provision of school buildings by Dutch municipalities. A cost function is estimated for the years 2005–2016 using stochastic frontier methods...journal article 2021

Blank, J.L.T. (author), Niaounakis, T.K. (author)Local governments may seek efficient public service delivery through scaling up production, and the quest for the optimal local government size has attracted extensive attention of scholars and policy makers. Indeed, if scale matters for local government efficiency, increasing size may be a key factor in achieving more value for money for...journal article 2021

Blank, B. (author), Barletta, V. (author), Hu, H. (author), Pappa, F. (author), van der Wal, W. (author)Accurate glacial isostatic adjustment (GIA) models are required for correcting measurements of mass change in Antarctica and for improving knowledge of the sub-surface, especially in areas of large current ice loss such as the Amundsen Sea Embayment (ASE). Regionally, seismic and gravity data suggests lateral differences in viscosity (3D)....journal article 2021

van der Wal, W. (author), van Calcar, C.J. (author), de Boer, Bas (author), Blank, B. (author)</p><p class="MsoNormal">Over glacial-interglacial cycles, the evolution of an ice sheet is influenced by Glacial isostatic adjustment (GIA) via two negative feedback loops. Firstly, vertical bedrock deformation due to a changing ice load alters ice-sheet surface elevation. For example, an increasing ice load leads to a lower bedrock...abstract 2020

Blank, J.L.T. (author)This article presents a one-stage efficiency frontier analysis based on the scaling property. This type of analysis is a not very often applied in empirical work in spite of its nice features. Due to the scaling property the influence of exogenous (managerial) variables on efficiency can be modelled and estimated in one stage. It also opens...journal article 2020

Blank, J.L.T. (author), Niaounakis, T.K. (author), Valdmanis, Vivian G. (author)BACKGROUND: The development of labour productivity is relevant for accurately planning future staffing requirements, especially in sectors where technological developments may drive labour substitution. The present study investigates how labour productivity has developed across Dutch medical specialists (2007-2017) and discusses its...journal article 2020

Blank, J.L.T. (author), Niaounakis, T.K. (author)In many countries, the provision of primary education is among the core responsibilities of local governments. One of the main questions local governments face concerns the optimal configuration of school boards and size of schools. In this paper we analyse the relation between cost and scale in school boards and in schools. The influence of...journal article 2019

Blank, J.L.T. (author), Enserink, B. (author), van Heezik, A.A.S. (author)In the last four decades, the Dutch drinking water industry has undergone two major policy reforms, namely the consolidation of the industry by stimulating mergers and the introduction of yardstick competition by applying benchmarks. This paper addresses the question of whether these two instruments have improved productivity. Productivity...journal article 2019

Blank, J.L.T. (author), van Heezik, A.A.S. (author)The judiciary is constantly undergoing change in order to respond to a wide range of social developments that have brought the sector under increasing pressure. In order to deal with the constant call for enhancing budgets, different policy measures have been taken to downsize the appeal to the judiciary and to improve productivity. One of...journal article 2019

(author)Differences in predictions of Glacial Isostatic Adjustment (GIA) for Antarctica persist due to uncertainties in deglacial history and Earth rheology. The Earth models adopted in many GIA studies are defined by parameters that vary in the radial direction only and represent a global average Earth structure (referred to as 1-D Earth models)....journal article 2018

Blank, J.L.T. (author)The academic literature provides excellent methodologies to identify best practices and to calculate inefficiencies by stochastic frontier analysis. However, these methodologies are regarded as a black box by policy makers and managers and therefore results are hard to accept. This paper proposes an alternative class of stochastic frontier...journal article 2018

van Hulst, B.L. (author), Blank, J.L.T. (author)Door fusies zijn Nederlandse ziekenhuizen in de laatste decennia steeds groter geworden. Uit een meta-analyse van internationale studies blijkt dat de zorgkosten juist het laagst zijn in ziekenhuizen die kleiner zijn dan de meeste Nederlandse ziekenhuizen. Het is daarom onwaarschijnlijk dat verdere schaalvergroting de zorgkosten zal drukken.journal article 2017

Blank, J.L.T. (author), van Hulst, B.L. (author)Voor de Spoedeisende Hulp gelden economische schaalvoordelen. Anders gezegd: bij een grotere SEH zijn de gemiddelde kosten per patiënt lager. Toch is dit geen reden om concentratie van de SEH ’s na te streven. Besparingen op kosten bij de SEH worden namelijk tenietgedaan door oplopende kosten in het vervolgtraject.journal article 2017
