Elsinga, M.G. (author), Hoekstra, J.S.C.M. (author), Sedighi, S.M.A. (author), Taebi, B. (author)A perusal of the literature on housing debates reveals that the term ‘value’ is mostly applied to express the financial value of a house and is dealt with in economic literature. However, an alternative meaning of the word ‘value’ in the housing literature can be found in research into the values underlying housing preferences, applying research...journal article 2020

Sun, Junzi (author), Hoekstra, J.M. (author), Ellerbroek, Joost (author)In air traffic management research, aircraft performance models are often used to generate and analyze aircraft trajectories. Although a crucial part of the aircraft performance model, the aerodynamic property of aircraft is rarely available for public research purposes, as it is protected by aircraft manufacturers for commercial reasons. In...journal article 2020

Schlathölter, Thomas (author), Mostafa, Yahia (author), Kamman, Amber (author), Dongelmans, Arnold (author), Arribard, Yann (author), Cazaux, S.M. (author), Hoekstra, Ronnie (author)Abstract: When exposed to a thermal beam of hydrogen atoms, gas-phase coronene cations C<sub>24</sub>H<sub>12</sub><sup>+</sup> can be sequentially hydrogenated. This process is accompanied by a gradual transition of the electronic structure from aromatic to aliphatic. The planar very stable coronene structure transforms into the...journal article 2020

Hoekstra, J.S.C.M. (author)This paper makes a plea for a new form of international comparative housing research, in which not countries (national housing regimes) but cities or regions (local housing regimes) are the unit of analysis. Why do we need such a new comparative research approach? How can a local housing regime be conceptualised? By answering these questions,...journal article 2020

(author), Friedman, Joshua (author)Coastal management in the Netherlands has the aim to defend coastal zones by preventing flooding and mitigating erosion. To that end, large-scale nourishments are placed in the nearshore, which are supposed to dynamically preserve the coastal zone over a timescale of years. To assess their effectiveness, these nourishments are monitored over...journal article 2020

Sun, Junzi (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Open access to flight data from Automatic Dependent Surveillance-Broadcast (ADS-B) has provided researchers with more insights for air traffic management than aircraft tracking alone. With large quantities of trajectory data collected from a wide range of different aircraft types, it is possible to extract accurate aircraft performance...journal article 2019

Sunil, E. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author), Maas, J.B. (author)This paper presents analytical models that describe the safety of unstructured and layered en route airspace designs. Here, ‘unstructured airspace’ refers to airspace designs that offer operators complete freedom in path planning, whereas ‘layered airspace’ refers to airspace concepts that utilize heading-altitude rules to vertically separate...journal article 2018

Hoekstra, J.S.C.M. (author)The Dutch social rental sector often serves as an example for other countries as a result of its large share and good quality housing. However, many things have changed in the sector in recent years. After 2011, the central government has regained its control over the housing associations. This was needed after the unacceptable amount of...journal article 2017

(author), Hoekstra, Alfons G. (author)The presence of collaterals and high thrombus permeability are associated with good functional outcomes after an acute ischaemic stroke. We aim to understand the combined effect of the collaterals and thrombus permeability on cerebral blood flow during an acute ischaemic stroke. A cerebral blood flow model including the leptomeningeal...journal article 2022

Jansen, S.J.T. (author), Hoekstra, J.S.C.M. (author), Boumeester, H.J.F.M. (author)The extraction of natural gas in the north of The Netherlands has led to soil subsidence and the occurrence of earthquakes. Residents worry about the safety of their families and the saleability of their dwelling and might want to move. The goal is to examine whether the earthquakes are related to the intention to move. A survey among...journal article 2017

Gentili, M. (author), Hoekstra, J.S.C.M. (author)According to basic economics, when vacancy rates rise, house prices should decrease and vice versa, responding to supply and demand mechanisms. However, previous studies have observed that, before the economic crisis, this was not the case in Spain and Malta. It has been questioned whether this paradox is a Mediterranean phenomenon or simply the...journal article 2018

Deng, W. (author), Hoekstra, J.S.C.M. (author), Elsinga, M.G. (author)After three decades of housing reform in China, housing assets constitute a sizable share of family wealth but are distributed unevenly, as registered homeowners are predominantly male. This is partly because males generally have higher incomes than females and can therefore contribute more to the financing, but also because males receive more...journal article 2018

Low carbon heating and cooling by combining various technologies with Aquifer Thermal Energy StoragePellegrini, M. (author), Bloemendal, Martin (author), Hoekstra, N. (author), Spaak, G. (author), Andreu Gallego, A. (author), Rodriguez Comins, J. (author), Grotenhuis, T. (author), Picone, S. (author), Murrell, A. J. (author)A transition to a low carbon energy system is needed to respond to global challenge of climate change mitigation. Aquifer Thermal Energy Storage (ATES) is a technology with worldwide potential to provide sustainable space heating and cooling by (seasonal) storage and recovery of heat in the subsurface. However, adoption of ATES varies strongly...journal article 2019

Marais, Lochner (author), Hoekstra, J.S.C.M. (author), Napier, Mark (author), Cloete, Jan (author), Lenka, Molefi (author)Under apartheid, black African households could not own land or homes in most major urban centres in South Africa. This limited residential mobility and locked many households into state rental accommodation in townships. Homeownership for all South Africans was restored in the mid-1980 s and the Group Areas Act was repealed in 1991.<br/...journal article 2018
