- Critical infrastructures for fuel, food, transport and the payment system become inceasingly entangled. Disruptions in the payment system can quickly lead to cascading effects and even the responses of actors in the various sectors are interrelated, which can cause escalation if the collaborative responses are not well-aligned. Our contribution to the track of Human Factors and simulation discusses how gaming-simulation can be used as a training environment where groups of practitioners can learn to develop in-depth understanding of system behaviour (i.e. cascading effects of disruptions) and learn how to develop collaborative resilience across many different critical infrastructures. More specifically, our paper focuses on the development and application of a mixed-methods assessment approach in the simulation-game. The assessment method captures qualitative as well as quantitative aspects of resilience and team-work. It can be used to assess the value of our simulation-game and to increase insight in what collective resilience actually implies.

Cognitive work analysis and conceptual designing for unmanned air traffic management in cities

- Cognitive Work Analysis (CWA) is an appropriate approach in high-stakes domains, such as Air Traffic Management (ATM). It provides focus on human expert performance in regular as well as contingency situations. However, CWA is not suitable for the design of a first-of-a-kind system, since there is nothing to analyze before the start of the design process. In 2017, unmanned traffic management (UTM) for intense drone traffic in cities was such a system. Making things worse, the UTM system has to be in place before the traffic, since it provides basic safety. In this paper we present conceptual designing as a bootstrapping approach to CWA for UTM as a first-of-a-kind system.

- Progression bars and spinners have long been the norm when providing feedback during wait times on the web. However, a more recent trend is the use of skeleton screens. This paper aims to evaluate the usefulness of skeleton screens as an alternative to spinners. This is done user testing a fictional news site with two variations, one showing skeleton screens before content is loaded, and another utilizing spinners. Both a questionnaire and measuring timing while finding a specified article when entering a website for the first time was used. The results show that the page using skeleton screens, scored higher on average on both perceived speed and ease of navigation. However, people using the page with spinners were faster at finding the article when entering the site for the first time. The results of this paper cannot show any significant differences in any of the comparisons between the web pages.

The User' Time Perception : The effect of various animation speeds on loading screens

- Loading screens are still important in 2018, and there is a reason for that: they provide a great way to give feedback to the user in the interface during wait times after a user's action. Previous research shows that it is essential for a well designed interface and it is a well established way to increase and maintain a user's satisfaction. This study specifically examine the looped, passive animation screen with regards to how the animation speed affects the user. Results suggests that with faster animation, perceived wait time gets shorter and the user is more satisfied.
