Mercuur, R.A. (author), Dignum, M.V. (author), Jonker, C.M. (author)Inducing behavioural change requires a good understanding of how habits break. We identified two theories in the psychological literature on this process: the decrease theory and persist theory. Both theories are used to explain behavioural change, but one states the original habit fades out, while the other theory states the habit persists. We...conference paper 2021

Cavalcante Siebert, L. (author), Mercuur, R.A. (author), Dignum, M.V. (author), van den Hoven, M.J. (author), Jonker, C.M. (author)Autonomous agents (AA) will increasingly be interacting with us in our daily lives. While we want the benefits attached to AAs, it is essential that their behavior is aligned with our values and norms. Hence, an AA will need to estimate the values and norms of the humans it interacts with, which is not a straightforward task when solely...conference paper 2020

Ebrahimi Fard, A. (author), Mercuur, R.A. (author), Dignum, M.V. (author), Jonker, C.M. (author), van de Walle, B.A. (author)Rumour is a collective emergent phenomenon with a potential for provoking a crisis. Modelling approaches have been deployed since five decades ago; however, the focus was mostly on epidemic behaviour of the rumours which does not take into account the differences between agents. We use social practice theory to model agent decision-making in...conference paper 2020

LeRon Shults, F. (author), Wildman, Wesley J. (author), Dignum, M.V. (author)This paper describes a framework for ethical analysis of the practice of computer Modeling & Simulation (M&S). Each of the authors presents a computational model as a case study and offers an ethical analysis by applying the philosophical, scientific, and practical components of the framework. Each author also provides a constructive...conference paper 2019

Larsen, John Bruntse (author), Dignum, M.V. (author), Villadsen, Jørgen (author), Dignum, Frank (author)Understanding the social contexts in which actions and interactions take place is of utmost importance for planning one’s goals and activities. People use social practices as means to make sense of their environment, assessing how that context relates to past, common experiences, culture and capabilities. Social practices can therefore...conference paper 2018

(author), de Wildt, T.E. (author)Ethics by Design concerns the methods, algorithms and tools needed to endow autonomous agents with the capability to reason about the ethical aspects of their decisions, and the methods, tools and formalisms to guarantee that an agent's behavior remains within given moral bounds. In this context some questions arise: How and to what extent...conference paper 2018

Pigmans, K.A.M. (author), Aldewereld, Huib (author), Dignum, V (author), Doorn, N. (author)Decision-making processes involving multiple stakeholders can be rather cumbersome, turbulent and lengthy. The stance of some stakeholders, upholding their individual interests, can slowdown or even block such processes. Recent research suggests that a focus on the values of the stakeholders could benefit those decision-making processes. However...conference paper 2017

Pigmans, K.A.M. (author), Aldewereld, Huib (author), Doorn, N. (author), Dignum, V (author)Decision-making processes in policy making with multiple-stakeholders can be complex because of the technically advanced systems that are decided upon, e.g. water management systems. But the complexity is often also caused by social dependencies and interests at stake. This can lead to processes in which stakeholders firmly defend their...conference paper 2016

King, T.W. (author), Dignum, M.V. (author), Jonker, C.M. (author)Institutions regulate societies. Comprising Searle's constitutive counts-as rules, "A counts-as B in context C", an institution ascribes from brute and institutional facts (As), a social reality comprising institutional facts (Bs) conditional on the social reality (contexts Cs). When brute facts change an institution evolves from one social...conference paper 2016

(author), Cligge, Martijn (author), Timmermans, Jan (author), Segers, Lennard (author)Nowadays, public debates often take place on social media platforms like Facebook or Twitter and can be characterized as asynchronous, protracted and ill-structured. The Massive Open Online Deliberation (MOOD) platform aims to structure these debates. Essential is that the platform can differentiate between the moral acceptability and the social...conference paper 2016

Dignum, V. (author), Aldewereld, H.M. (author), Vasconcelos, W. (author)Norms have been used to represent desirable behaviours that software agents should exhibit in sophisticated multi-agent solutions. An important open research issue refers to group norms, i.e. norms that govern groups of agents. Depending on the interpretation, group norms may be intended to affect the group as a whole, each member of a group, or...conference paper 2015

Van Bueren, E.M. (author), Dignum, M. (author), Steenhuisen, B.M.

How are SEAPs aiming to contribute to the process of local energy transition and how can their performance be improved? The text of thirty...conference paper 2015

Hesan, R. (author), Ghorbani, A. (author), Dignum, M.V. (author)In system dynamics modeling, differential equations have been used as the basic mathematical operator. Using difference equation to build system dynamics models instead of differential equation, can be insightful for studying small organizations or systems with micro behavior. In this paper we explain how we can use difference equations to build...conference paper 2014

Dignum, V. (author), Jonker, C.M. (author), Prada, R. (author), Dignum, F.

We claim that a fundamental new approach based on social concepts is needed to build these socially intelligent systems. In this paper, we explore how the concepts of social practices and social identities can be...conference paper 2014

They can be regulated through organizations similar to human organizations, which regulate the agents’ behavior space and describe the expected behavior of the agents. Agents need...conference paper 2014
