In this contribution, we investigate how results from the ongoing discussion about e-Infrastructures can be used to improve design of IT infrastructures in organizations. We first establish a perspective on organizational as work infrastructure that focuses infrastructural nature Information Systems and describe challenges for designing within type infrastructure. Then elaborate possible use concepts e-infrastructure discussion, particular concept infrastructuring it was developed by Star...
Information and communications technology (ICT) pervades most aspects of our lives changes everyday's practices in work leisure time. When designing innovative ICTs, we need to engage with given practices, institutional arrangements, technological infrastructures. We describe the research framework used at University Siegen. It is based on a collection design case studies particular fields practice identifies cross-cutting issues compare aggregate insights between these cases. To illustrate...
In this paper, the authors propose a systematization of social software use in crisis situations, examining different types cooperation and challenges. The discuss how organizational actors involved management (police, fire-fighters, organizations, etc.) affected citizens are communicating can communicate collaborate through software. After defining term ‘social software,’ outline its management. They present two case studies where they have examined 2010: first during disruption air travel...
Emergencies such as the 2013 Central European flood or typhoon Haiyan in Philippines have shown how citizens can organize themselves and coordinate private relief activities. These activities be found (physical) groups of affected people, but also within (digital) social media communities. There is an evident need, however, for a clearer picture what exactly going on to available use by official emergency services: enlist them, keep them safe, support their efforts avoid needless...
Recent disasters have shown an increase in the significance of social media for both affected citizens and volunteers alike coordination information organization relief activities, often independently addition to official emergency response. Existing research mainly focuses on way which individual platforms are used by response disasters. This paper examines use during European Floods 2013 proposes a novel cross-social-media application volunteers. Besides comprehensive analysis volunteer...
Most participation processes in urban planning offer poor incentives, especially for young citizens, hence important citizen's needs are excluded. Our work aims at identifying the degree to which Augmented Reality (AR) might motivate people. We developed an AR-app with Unity3D create new interaction concepts use cases planning. Building projects and environment changes visualized, so citizens can contribute design ideas process. Using a human-centered approach, we invited different...
Improvisation is necessary when planned decision-making as the main managerial activity does not fit conditions practice provides. In these cases, information technology should just automate and structured decisions, but support improvisational practice. this contribution we present an empirical study about improvisation work in scenarios of medium to large power outages Germany. Our focus on inter-organizational cooperation practices, thus examined fire departments, police, public...
Over the last years, digital fabrication technologies such as 3D printers have become more and common at universities small businesses well in communities of hobbyist makers. The high complexity technologies, rapid technological progress close link between hardware software this field poses challenges for users communites learning how to operate these machines, especially contexts existing (and changing) practices. We present an empirical study on appropriation two different derive design...
People all over the world are regularly affected by disasters and emergencies. Besides official emergency services, ordinary citizens getting increasingly involved in crisis response work. They usually present on-site at place of incident use social media to share information about event. For large amount citizen-generated content media, however, means that finding high-quality is similar “finding a needle haystack”. This article presents an approach how dynamic subjective quality assessment...
Emergencies are characterized by high complexity and unpredictability. In order to assess manage them successfully, improvisation work informal communication, even beyond local organizational boundaries, is needed. Such practices can facilitate ad hoc participation of units in situation assessment, but this may lack overall awareness. This article presents a study on how emergent “collaboration needs” current response teams located on-site the control center could be supported mobile...
