By combining different perspectives and methods of empirical research, this PhD thesis<br/>generates multi-disciplinary insights into the rise of the logistics complex and its planning<br/>discourse whilst focusing specifically on XXL distribution centres (DCs) in the Netherlands.<br/>Since the 1980s, the building footprint of this complex has...

Nefs, Merten (author)
The spatial planning of logistics is an emerging topic due to scarcity of land, environmental impacts and the transition to a circular economy. This paper proposes a policy information tool for these issues, including a new logistics cluster typology applied in suitability maps. The validity and applicability of this tool are tested in a Dutch...

In the Netherlands, a shift occurred over the last two decades from positively framed spatial-economic policies promoting the development of extra-large distribution centres (DCs) and their claimed positive employment benefits towards a critical stance questioning the benefits of such policies, fuelled by the connected debate regarding the...

This chapter revisits the most significant international definitions of the metropolitan landscape. It shows methods of mapping and measuring the metropolitan landscape, most of them developed at TU Delft. Additionally, it discusses one of the tools that can be used to develop the metropolitan landscape and reflect on its qualities and...

Trade infrastructure and logistical activities have long been a source of prosperity as well as nuisance. The gains and pains of logistics, however, are not distributed equally across regions and cities. Important trade hubs such as Rotterdam or Chicago have built strong trade institutions and accumulated urban wealth, hereby making a successful...

Like other countries with large ports, the Netherlands developed a policy narrative to acquire a key position in global value chains starting in the 1980s, through the spatial development of its hinterland logistics complex. The negative environmental effects of logistics, such as landscape transformation and congestion, have increasingly come...

In Europe, very large distribution centres (XXL DCs) are increasingly appearing on planning agendas due to their growing spatial footprint and environmental impacts. Although the emergence of XXL DCs has gained traction in academic research, empirical knowledge about the process that leads to their oft-debated location choice, geometry and...

Previous research has shown that the material properties of a three-dimensional printed strain hardening cementitious composite (3DP-SHCC) can significantly vary, depending on the printing system with which it is produced. However, limited research has been performed on the reproducibility of hardened mechanical properties under identical...

Over the past few years, several studies have shown the potential of three-dimensional concrete printing (3DCP) for applications in building and civil engineering. However, only a few studies have compared the properties of the fresh printing material and the quality of the printed elements from different printing facilities. Variations in the...

This paper investigates the influence of depth of field on change detection in both pictorial and solid scenes. In this work, a within-subjects experiment is conducted using a flicker paradigm, with which the hit rate and response time for change detection are obtained. The results show that depth of field has effects on change detection: the...

Depth of field (DOF) is defined as the distance range within which objects are perceived as sharp. Previous research has focused on blur discrimination in artificial stimuli and natural photographs. The discrimination of DOF, however, has received less attention. Since DOF introduces blur which is related to distance in depth, many levels of...

In virtual reality exposure therapy (VRET) for anxiety disorders, sense of presence in the virtual environment is considered the principal mechanism that enables anxiety to be felt. Existing studies on the relation between sense of presence and level of anxiety, however, have yielded mixed results on the correlation between the two. In this meta...

In this paper we report two experiments in which the effect of perspective projection on presence and space perception was investigated. In Experiment 1, participants were asked to score a presence questionnaire when looking at a virtual classroom. We manipulated the vantage point, the viewing mode (binocular versus monocular viewing), the...

Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation and convergence cues that may specify different distances in depth. Earlier research has shown that depth-of-field,...

In this paper, we focus on how people perceive the aspect ratio of city squares. Earlier research has focused on distance perception but not so much on the perceived aspect ratio of the surrounding space. Furthermore, those studies have focused on “open” spaces rather than urban areas enclosed by walls, houses and filled with people, cars, etc....

The question whether feelings of anxiety are confounded with cybersickness in studies on virtual reality exposure therapy (VRET) was raised since the questionnaires used to measure them contain overlapping items. In the experiment, 88 participants were asked to talk in front of a virtual audience. Previous research has shown that this task may...
