    Scenarios of Robot-Assisted Play for Children with Cognitive and Physical Disabilities.Ben Robins, Kerstin Dautenhahn, Ester Ferrari, Gernot Kronreif, Barbara Prazak-Aram, Patrizia Marti, Iolanda Iacono, Gert Jan Gelderblom, Tanja Bernd, Francesca Caprino & Elena Laudanna - 2012 - Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies / Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies 13 (2):189-234.
    This article presents a novel set of ten play scenarios for robot-assisted play for children with special needs. This set of scenarios is one of the key outcomes of the IROMEC project that investigated how robotic toys can become social mediators, encouraging children with special needs to discover a range of play styles, from solitary to collaborative play. The target user groups in the project were children with Mild Mental Retardation,1 children with Severe Motor Impairment and children with Autism. The (...)

    GRASP Agents: Social First, Intelligent Later.Gert Jan Hofstede - 2019 - AI and Society 34 (3):535-543.
    This paper urges that if we wish to give social intelligence to our agents, it pays to look at how we acquired our social intelligence ourselves. We are born with drives and motives that are innate and deeply social. Next, as children we are socialized to acquire norms and values and to understand rituals large and small. These social elements are the core of our being. We capture them in the acronym GRASP: Groups, Rituals, Affiliation, Status, Power. As a consequence, (...)

  4. Computational Meta-Ethics: Towards the Meta-Ethical Robot.Gert-Jan C. Lokhorst - 2011 - Minds and Machines 21 (2):261-274.
    It has been argued that ethically correct robots should be able to reason about right and wrong. In order to do so, they must have a set of do’s and don’ts at their disposal. However, such a list may be inconsistent, incomplete or otherwise unsatisfactory, depending on the reasoning principles that one employs. For this reason, it might be desirable if robots were to some extent able to reason about their own reasoning—in other words, if they had some meta-ethical capacities. (...)

    An Intuitionistic Reformulation of Mally’s Deontic Logic.Gert-Jan C. Lokhorst - 2013 - Journal of Philosophical Logic 42 (4):635-641.
    In 1926, Ernst Mally proposed a number of deontic postulates. He added them as axioms to classical propositional logic. The resulting system was unsatisfactory because it had the consequence that A is the case if and only if it is obligatory that A. We present an intuitionistic reformulation of Mally’s deontic logic. We show that this system does not provide the just-mentioned objectionable theorem while most of the theorems that Mally considered acceptable are still derivable. The resulting system is unacceptable (...)

    Mally’s Deontic Logic.Gert-Jan Lokhorst - 2004 - Grazer Philosophische Studien.
    In 1926, Mally presented the first formal system of deontic logic. His system had several consequences which Mally regarded as surprising but defensible. It also, however, has the consequence that A is obligatory if and only if A is the case, which is unacceptable from the point of view of any reasonable deontic logic. We describe Mally's system and discuss how it might reasonably be repaired.

    On Possibilities for Action: The Past, Present and Future of Affordance Research.Gert-Jan Pepping, Joanne Smith, Frank T. J. M. Zaal & Annemiek D. Barsingerhorn - 2012 - Avant: Trends in Interdisciplinary Studies 3 (2):54-69.
    We give a historical overview of the development of almost 50 years of empirical research on the affordances in the past and in the present. Defined by James Jerome Gibson in the early development of the Ecological Approach to Perception and Action as the prime of perception and action, affordances have become a rich topic of investigation in the fields of human movement science and experimental psychology. The methodological origins of the empirical research performed on affordances can be traced back (...)

    Reasoning About Actions and Obligations in First-Order Logic.Gert-Jan C. Lokhorst - 1996 - Studia Logica 57 (1):221 - 237.
    We describe a new way in which theories about the deontic status of actions can be represented in terms of the standard two-sorted extensional predicate calculus. Some of the resulting formal theories are easy to implement in Prolog; one prototype implementation--R. M. Lee's deontic expert shell DX--is briefly described.

  10. Andersonian Deontic Logic, Propositional Quantification, and Mally.Gert-Jan C. Lokhorst - 2006 - Notre Dame Journal of Formal Logic 47 (3):385-395.
    We present a new axiomatization of the deontic fragment of Anderson's relevant deontic logic, give an Andersonian reduction of a relevant version of Mally's deontic logic previously discussed in this journal, study the effect of adding propositional quantification to Anderson's system, and discuss the meaning of Anderson's propositional constant in a wide range of Andersonian deontic systems.

  11. Ontology, Semantics and Philosophy of Mind in Wittgenstein's Tractatus: A Formal Reconstruction. [REVIEW]Gert Jan Lokhorst - 1988 - Erkenntnis 29 (1):35 - 75.
    The paper presents a formal explication of the early Wittgenstein's views on ontology, the syntax and semantics of an ideal logical language, and the propositional attitudes. It will be shown that Wittgenstein gave a language of thought analysis of propositional attitude ascriptions, and that his ontological views imply that such ascriptions are truth-functions of (and supervenient upon) elementary sentences. Finally, an axiomatization of a quantified doxastic modal logic corresponding to Tractarian semantics will be given.

  13. Ernst Mally's Deontik (1926).Gert-Jan C. Lokhorst - 1999 - Notre Dame Journal of Formal Logic 40 (2):273-282.
    In 1926, Mally proposed the first formal deontic system. As Mally and others soon realized, this system had some rather strange consequences. We show that the strangeness of Mally's system is not so much due to Mally's informal deontic principles as to the fact that he formalized those principles in terms of the propositional calculus. If they are formalized in terms of relevant logic rather than classical logic, one obtains a system which is related to Anderson's relevant deontic logic and (...)

    The Fluid Nature of Water Grabbing: The on-Going Contestation of Water Distribution Between Peasants and Agribusinesses in Nduruma, Tanzania.Chris de Bont, Gert Jan Veldwisch, Hans Charles Komakech & Jeroen Vos - 2016 - Agriculture and Human Values 33 (3):641-654.
    This article contributes to the contemporary debate on land and water grabbing through a detailed, qualitative case study of horticultural agribusinesses which have settled in Tanzania, disrupting patterns of land and water use. In this paper we analyse how capitalist settler farms and their upstream and downstream peasant neighbours along the Nduruma river, Tanzania, expand and defend their water use. The paper is based on 3 months of qualitative field work in Tanzania. We use the echelons of rights analysis framework (...)

    The Dialectics of Paul: On Exception, Grace, and Use in Badiou and Agamben.Gert-Jan van der Heiden - 2016 - International Journal of Philosophy and Theology 77 (3):171-190.
    ABSTRACTThe remarkable philosophical present-day turn to Paul pays a lot of attention to the particular role played by the famous distinctions that structure Paul’s rhetoric such as the distinction between faith and law, life and death, and spirit and flesh. These distinctions lead to the question of whether Paul endorses a dualism or not. In this essay, the author investigates Badiou’s and Agamben’s readings of Paul and asks whether one cannot find a form of dialectics rather than dualism in these (...)

    The Ethics of Assessing Health Technologies.Gert Jan van der Wilt, Rob Reuzel & H. David Banta - 2000 - Theoretical Medicine and Bioethics 21 (1):101-113.
    Health technology assessment consists of thesystematic study of the consequences of theintroduction or continued use of the technology in aparticular context, with the explicit objective toarrive at a judgment of the value or merit of thetechnology. Ideally, it is aimed at assessing allaspects of a given technology or group oftechnologies, including non-technical, e.g.socio-ethical, aspects. However, methods for assessingsocio-ethical implications of health technology arerelatively undeveloped and few mechanisms exist totake action based on the results of such evaluations.Still, the examples of cochlear (...)

    The Status–Power Arena: A Comprehensive Agent-Based Model of Social Status Dynamics and Gender in Groups of Children.Gert Jan Hofstede, Jillian Student & Mark R. Kramer - forthcoming - AI and Society:1-21.
    Despite the urgency of this issue, AI still struggles to represent social life. This article presents a comprehensive agent-based model that investigates status-power dynamics in groups. Kemper’s sociological status–power theory of social relationships, and a literature review on school children in middle youth, is its basis. The model allows us to investigate causation of the near-ubiquitous phenomenon that females have lower social status on average than males. Possible causes included in the model are children’s dispositional traits, schoolyard culture, behavioural strategy (...)

    Engineering and the Problem of Moral Overload.Jeroen Van den Hoven, Gert-Jan Lokhorst & Ibo Van de Poel - 2012 - Science and Engineering Ethics 18 (1):143-155.
    When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint and technological progress can create moral progress rather than just moral problems. We show this by (...)

    De mens is in de afgelopen drie eeuwen vaak vergeleken met allerlei soorten machines. In de achttiende eeuw was de klokmetafoor tamelijk populair; psychologische termen als ‘drijfveer’, ‘van slag raken’ en ‘opgewonden zijn’ herinneren hier nog aan [Vroon and Draaisma, 1985]. In de negentiende eeuw overheerste de stoommachine-metafoor. De psychologie van Freud wordt wel als een uitgewerkte versie van deze metafoor beschouwd [Russelmann, 1983]. Ook uitdrukkingen als ‘uitlaatkleppen’, ‘stoom afblazen’ en ‘iemand opstoken’ zijn eraan te danken. De stoommachine-metafoor wordt nog (...)

    Mally’s Deontic Logic: Reducibility and Semantics.Gert-Jan C. Lokhorst - 2015 - Journal of Philosophical Logic 44 (3):309-319.
    We discuss three aspects of the intuitionistic reformulation of Mally’s deontic logic that was recently proposed ). First, this reformulation is more similar to Standard Deontic Logic than appears at first sight: like Standard Deontic Logic, it is Kanger reducible and Anderson reducible to alethic logic and it has a semantical interpretation that can be read in deontic terms. Second, this reformulation has an extension that provides 100% of the theorems stated by Mally himself. Third, it is interesting to view (...)

    Distantiatie in de Hermeneutiek Van Paul Ricoeur.Gert-jan van der Heiden - 2007 - Bijdragen 68 (3):277-297.
    One of the key concepts of Paul Ricoeur’s hermeneutics is the notion of distanciation. In this article we show that Ricoeur introduces this notion as a correction of Heidegger’s focus on being-in and Gadamer’s emphasis on belonging . Ricoeur argues that distanciation does not lead to the uprooting of our belonging to a tradition. Rather, distanciation is an integral part of the dynamics that constitutes tradition. We discuss the different senses in which Ricoeur understands distanciation as a positive and productive (...)

    Cost-Effectiveness Analysis of Health Care Services, and Concepts of Distributive Justice.Gert Jan van der Wilt - 1994 - Health Care Analysis 2 (4):296-305.
    Two answers to the question ‘how can we allocate health care resources fairly?’ are introduced and discussed. Both utilitarian and egalitarian approaches are found relevant, but both exhibit considerable theoretical and practical difficulties. Neither seems capable of solving the problem on its own. It is suggested that, for practical purposes, a version of Rawls' famous thought experiment might provide at least some enlightenment about which theoretical approach should be used to address the question.

    Health Care and the Principle of Fair Equality of Opportunity.Gert Jan van der Wilt - 1994 - Bioethics 8 (4):329–349.
    ABSTRACTIn The Netherlands, the public funding of a number of health care services is controversial. What can we learn from this about the moral concerns that underlie these judgements? And, if there is anything to learn, can we use this improved understanding to scrutinise the adequacy of particular decisions concerning the public funding of health care services? In the present paper, I will analyse three cases: corrective surgey, In Vitro Fertilisation and liver transplantation. I will summarise the arguments that have (...)
