More than 95 % of the total housing stock in the Netherlands is connected to central sewerage systems and in most cases the wastewater is treated biologically. As connection to central sewerage systems has reached its economic limits, interest in on-site treatment of the domestic wastewater of the remaining premises is increasing. A large scale research programme into on-site wastewater treatment up to population equivalents of 200 persons has therefore been initiated by the Dutch Ministry of Housing, Physical Planning and Environment. Intensive field-research work did establish that the technological features of most on-site biological treatment systems were satisfactory. A large scale implementation of these systems is however obstructed in different extents by problems of an organisational, financial and/or juridical nature and management difficulties. At present research is carried out to identify these bottlenecks and to analyse possible solutions. Some preliminary results are given which involve the following ‘bottlenecks':-legislation: absence of co-ordination and absence of a definition of ‘surface water';-absence of subsidies;-ownership: divisions in task-setting of Municipalities and Waterboards; divisions involved with cost-sharing;-inspection; operational control and maintenance; organisation of management;-discharge permits;-pollution levy;-sludge disposal. Final decisions and practical elaboration of policies towards on-site treatment will have to be formulated in a broad discussion with all the authorities and interest groups involved.

During the 2015 refugee crisis in Europe, temporary refugee shelters arose in the Netherlands to shelter the large influx of asylum seekers. The largest shelter was located in the eastern part of the country. This shelter, where tents housed nearly 3,000 asylum seekers, was managed with a firm top-down approach. However, many residents of the shelter—mainly Syrians and Eritreans—developed horizontal relations with the local receiving society, using social media to establish contact and exchange services and goods. This case study shows how various types of crisis communication played a role and how the different worlds came together. Connectivity is discussed in relation to inclusion, based on resilient (non-)humanitarian approaches that link society with social media. Moreover, we argue that the refugee crisis can be better understood by looking through the lens of connectivity, practices, and migration infrastructure instead of focusing only on state policies.

<p>Should a bridge always be functional and accessible? Should it always fulfil its purpose? This seemingly self- evident question is a key question in footbridge design that is oriented towards creating experiences.</p><p>Footbridges are able to successfully enriches our experience of a certain context or landscape, it cannot be functional all the time, under all environmental conditions, weather and seasons. A good example is the Zalige bridge designed as part of the Room for the River, a large-scale national program for inland flood- protection in the Netherlands. Build upon the floodplains within a newly created river-park by the city of Nijmegen, the Zalige bridge’s curved shape stands in direct relationship to the fluctuating water levels of the river. When water levels rise, the bridge partially submerges, becoming only accessible through steppingstones. At peak heights, the bridge disappears completely, becoming a metaphor for our relationship to the water.</p><p>“Building a bridge that fails to fulfil its sole purpose of containing the water; this can only be pulled off in the Netherlands.” – jury Dutch Design Awards about the Zalige bridge.</p><p>The loss of functionality is directly related to the creation of an experience. When the water levels rose in January 2018, the bridge became the prime location to experience the changing landscape. It shows that engineering a bridge is not solely focussed on the most efficient engineering, but for the purpose it fulfils as for society. For most pedestrian bridges where the perception of the user is on a different level as for a highway bridge, functionality provides more than just cost driven or efficiency driven parameters. It is more related to the added value for the community. When design not solemnly derives from the sheer taste and predilection of the designer but is based on the user’s experience, it generates a durable relation with a feeling of ownership of its users. The key is to create this experience in an elegant and natural way and not forced or dictated. It should be people's own unique discovery and should not be imposed.</p>

Summary This article deals with the reception of Billy Graham and modern evangelicalism in the fragmented society of the Netherlands in 1954. It takes its departure from the stream of newspaper articles published between February and June in response to the Greater London Crusade and Graham’s first large scale rally in Amsterdam’s Olympic Stadium. The analysis of the reports in different newspapers, which represent the different social groups (catholic, protestant, socialist and liberal) in Dutch society, reveals a significant shift in the way Billy Graham was perceived: from initial scepticism to mild appreciation. This change in press coverage, it is concluded, is mainly due to the different way in which Billy Graham presented himself compared with the large-scale publicity which surrounded his campaign.

Celtic field research has so far been strongly focused on prospection and mapping. As a result of this there is a serious lack of knowledge of formation and land-use processes of these fields. This article describes a methodological case study in The Netherlands that may be applied to other European Celtic fields in the future. By interdisciplinary use of pedological, palynological and micromorphological research methods the authors were able to discern five development stages in the history of the field, dating from the late Bronze Age to the early Roman Period. There are strong indications that the earthen ridges, very typical for Celtic fields in the sandy landscapes of north-west Europe, were only formed in the later stages of Celtic field agriculture (late Iron Age and early Roman period). They were the result of a determined raising of the surface by large-scale transportation of soil material from the surroundings of the fields. Mainly the ridges were intensively cultivated and manured in the later stages of Celtic field cultivation. In the late Iron Age a remarkable shift in Celtic field agriculture took place from an extensive system with long fallow periods, a low level of manuring and extensive soil tillage to a more intensive system with shorter fallow periods, a more intensive soil tillage and a higher manuring intensity. There are also strong indications that rye (Secale cereale) was the main crop in the final stage of Celtic field agriculture.

Memory in journalism has largely been investigated in relation to the commemoration of historical key events. This article sheds light on everyday, less obvious forms of memory in journalism with a focus on non-commemorative memory. We carried out a large-scale content analysis of contemporary newspaper articles (n = 2799) about two historic storm surge disasters in the Netherlands (1953) and Germany (1962) and a subsequent qualitative study based on 10 interviews with Dutch and German journalists. Combining content-based results with actor views enabled us to look below the surface of memory in news reporting and lay bare potential triggers, justifications, and underlying motivations for memory use. We found that journalists frequently use memory to connect past, present, and future, driven by a range of professional, economic, ideological, and cultural motivations that go beyond commemoration. We propose the term “strategic motivations” to better understand the dynamics of memory in journalism.
