We describe the story of the railway missing links, particularly of the crossborder railway bridge in the Mura-Drava-Rails network. Eight railway lines formed this railway network from 1857 to 1924. We introduce our research with the historical case of design and innovation development of the semi- parabolic railway bridges. The central time frame of this paper is delimited to the post-second world war years to the present. With actor-network analysis, we describe the non-development and nonaction in the two cross-border railway regional lines, each with its missing link. These two missing links in an estimated length of twelve railway kilometres prevent the network from being reformed. Additionally, we draw insights from urban studies, development studies, and machine theory. We followed the logic of the nonreconstruction of the railway bridge on the border of the former Yugoslavia with the Republic of Austria and the rationalisation of the passenger railway transport in the former country in 1968 on the one side. That is how we tried to understand also the commissioning of the cross-border road bridge between the two countries over the Mura river only a year later, in 1969, on the other side. We had to broaden our research perspective to all the railway border crossing od today’s Slovenia with Austria, Hungary, and Italy. By mapping these railway border crossings, we were able to describe the strategic intent of the former country, which was to close the majority of the railway borders crossing— seven out of ten railway border crossings existing before the second world war—on its northern borders.

Post-war social housing estates are commonly problematised as socially and spatially segregated places in European cities. Physical transformations – often framed as ‘upgrading’ – are considered to stimulate better social and spatial integration: many estates are being ‘opened up’ by converting open spaces into public spaces, other estates are being densified to achieve a better social mix. In these transformations, social housing’s designed landscapes play a central role, but often with no awareness of their inherited socio-material qualities. This paper makes a case for reappraising the heritage of open spaces in post-war social housing as welfare landscapes to inform current debates, policies and practices regarding social housing and future heritage making in its renewal. We look back at the development processes of three paradigmatic Danish estates which literally materialised the emerging welfare state by concrete, asphalt, plantings and earthworks. Guided by actor-network theory we recount how their welfare landscapes materialised as socio-material assemblages. We show that non-human things played a crucial role in the development of welfare landscapes which focused on child welfare and community development, offered architectural and ecological diversity, and co-shaped the urban landscape beyond the individual estates. Understanding welfare landscapes as socio-material assemblages does not only acknowledge the role of non-human things in their historical production. Ultimately it also calls for the inclusion of the welfare of non-human species and may offer inspiration for developing future welfare landscapes for more than humans.

Social media occupies increasingly important roles in disaster response management. However, there are still doubts regarding the effectiveness of social media-based disaster communication. This paper aims to understand the discourse that emerge in Twitter containing facts or opinion regarding the flood disaster communication in DKI Jakarta under the different leadership of Basuki Tjahaja Purnama (2014- 2017) and Anies Rasyid Baswedan (2017-2020). This research used the methods of Corpus Assisted Discourse Study (CADS) and Actor Network Theory (ANT). These methods collected data on the discourse that is happening on Twitter and analyzes the network of actors who are active in discussions about floods in DKI Jakarta at different periods of leadership. This research found that the discourse that has developed on Twitter about floods in DKI Jakarta covers the personal problems of the leaders, the personality of the leaders, and the political position of the leaders, offered little messages that leads to solving the problem of flooding in DKI Jakarta. The active actor network is dominated by the local government of Jakarta as the responsibility holder or the main actor in delivering in information is only played by BPBD Jakarta.
