TY - JOUR A1 - Thiele, Lukas A1 - Pruin, Andree T1 - Does large-scale digital collaboration contribute to crisis management? T1 - Digitale Massenkollaboration als Teil von staatlichem Krisenmanagement? BT - an analysis of projects from the #WirVsVirus hackathon implemented in Germany during the COVID-19 pandemic BT - eine Analyse von Projekten aus dem #WirVsVirus-Hackathon in Deutschland JF - der moderne staat – Zeitschrift für Public Policy, Recht und Management N2 - In recent years, collaborative approaches to crisis management involving citizens have gained increasing attention. One example is the #WirVsVirus hackathon, which was conducted in response to the COVID-19 pandemic and had over 28,000 participants. Because research on large-scale, digital collaboration in crisis situations is scarce, consequences of their use in crisis management remain unclear. This article relies on the open governance paradigm as a lens for studying two projects emerging from the hackathon. Based on nine qualitative expert interviews, we ask how digital open governance affects governance capacity and legitimacy in crisis management. Our findings suggest that digital open governance can contribute to governance capacity and legitimacy, as it mobilises large, diverse groups of citizens to quickly develop citizen-centric, ready-to-use solutions for crisisrelated problems. However, we also identified potential problems, including risks regarding legitimacy and accountability, difficulties with scalable solutions, and questionable long-term impacts. N2 - Kollaborative, partizipative Instrumente zur Krisenbekämpfung haben in den letzten Jahren zunehmend an Aufmerksamkeit gewonnen. Ein Beispiel hierfür ist der #WirVsVirus-Hackathon, der als Reaktion auf die COVID-19-Pandemie durchgeführt wurde und über 28.000 Teilnehmer:innen erreichte. Bislang wurden die Auswirkungen solch groß angelegter, kollaborativer Ansätze zur Krisenbewältigung auf staatliches Krisenmanagement nur selten untersucht. Diese Studie analysiert den Hackathon und die daraus entstandenen Projekte aus der Perspektive des Open Governance-Paradigmas. Auf Grundlage von neun Experteninterviews untersuchen wir, wie sich digitale Open Governance auf die Regierungsfähigkeit und Legitimität in Krisenzeiten auswirkt. Unsere Analyse zeigt, dass digitale Open Governance zur Leistungsfähigkeit und Legitimität staatlichen Handelns in Krisenzeiten beitragen kann, da solche Projekte eine breite und diverse Teilnehmerschaft mobilisieren und in kurzer Zeit bürgerzentrierte, nutzbare Lösungen für krisenbezogene Probleme entwickeln können. Dem stehen allerdings Zweifel an der langfristigen Beständigkeit der Projekte, ihrer Skalierbarkeit, sowie Risiken hinsichtlich der Legitimität und Rechenschaftspflicht entgegen.

Interference is assumed to arise from overwriting of features shared by these items. The model was fit to time-accuracy data of memory-updating tasks from four experiments using nonlinear mixed effect (NLME) models as a framework. The model gave a good account of the data from a numerical and a spatial task version. The performance pattern in a combination of numerical and spatial updating could be explained by variations in the interference parameter: assuming less feature overlap between contents from different domains than between contents from the same domain, the model can account for double dissociations of content domains in dual-task experiments. Experiment 3 extended this idea to similarity within the verbal domain. The decline of memory accuracy with increasing memory load was steeper with phonologically similar than with dissimilar material, although processing speed was faster for the similar material. The model captured the similarity effects with a higher estimated interference parameter for the similar than for the dissimilar condition. The results are difficult to explain with alternative models, in particular models incorporating time-based decay and models assuming limited resource pools.

We argue that the pandemic and related policies led to increasing demands on public organisations and their employees. Following the job demands-resources model, we argue that resilience only can arise in the presence of resources for buffering these demands. Survey data were collected from 1,189 German public employees, 380 participants were included for analysis. The results suggest that the public service was resilient against the crisis and that the shift to telework was not as demanding as expected.
