The opportunity cost model (OCM) aims to explain various phenomena, among which the finding that performance degrades if executive functions are used repeatedly (). We argue that an OCM account of resource depletion requires two unlikely assumptions, and we discuss an alternative that does not require these assumptions. This alternative model describes the interplay between executive function and motivation.

Using telephone interviews among a random sample of 537 Dutch children aged 7–12 years old, we investigated the prevalence of fear reactions to television news among younger and older children and among boys and girls, what types of news items children in different age and gender groups refer to as frightening, and whether children's fear reactions to regular adult television news differed from their fear reactions to a special children's news program. Overall, 48.2 % of the children who reported watching (...) the adult or children's news programs, reported fear reactions to adult news, while 32.6 % reported fear of children's news content. For both types of news programs, younger children and girls more often reported fear than older children and boys did. The most prevalent fear-inducing news content categories were interpersonal violence, fires, accidents, and disasters, and visual depictions of the consequences of violence. (shrink)

Health technology assessment (HTA) is often biased in the sense that it neglects relevant perspectives on the technology in question. To incorporate different perspectives in HTA, we should pursue agreement about what are relevant, plausible, and feasible research questions; interactive technology assessment (iTA) might be suitable for this goal. In this way a kind of procedural ethics is established. Currently, ethics too often is focussed on the application of general principles, which leaves a lot of confusion as to what really (...) is the matter in specific cases; in an iTA clashes of values should not be approached by use of such ethics. Instead, casuistry, as a tool used within the framework of iTA, should help to articulate and clarify what is the matter, as to make room for explication and consensus building. (shrink)

I en række afhandlinger beskrives den hollandske ISAF styrkes indsats i Afghanisatn fra 2001-2010. I en fireårig periode fra 2006-2010 var det hollandske kontingent indsat i den afghanske provins Uruzgan og opnåede bemærkelsesværdige resultater. Sikkerhedssituationen blev forbedret, den økonomiske udvikling blev stabiliseret ligesom den offentlige administration, uddannelsen af børn og sundhedsplejen m.v. blev forbedret. Efter 2010 er provinsen overtaget af amerikanske og australske tropper.

For many physicists quantum theory contains strong conceptual difficulties, while for others the apparent conclusions about the reality of our physical world and the ways in which we discover that reality remain philosophically unacceptable. This book focuses on recent theoretical and experimental developments in the foundations of quantum physics, including topics such as the puzzles and paradoxes which appear when general relativity and quantum mechanics are combined; the emergence of classical properties from quantum mechanics; stochastic electrodynamics; EPR experiments and Bell's (...) Theorem; the consistent histories approach and the problem of datum uniqueness in quantum mechanics; non-local measurements and teleportation of quantum states; quantum non-demolition measurements in optics and matter wave properties observed by neutron, electron and atomic interferometry. Audience: This volume is intended for graduate students of physics and those interested in the foundations of quantum theory. (shrink)

This paper analyses the republican notion of non-domination from the viewpoint of individual dignity. It determines the aspect of individual dignity that republicans are concerned with and scrutinises how it is safeguarded by non-domination. I argue that the notion of non-domination as it is formulated by Pettit contains a number of ambiguities that need to be addressed. I discuss these ambiguities and argue for specific solutions that place great importance on a person’s moral beliefs and his status as a moral (...) being amongst others. Furthermore, I argue that the impunity interpretation is to be favoured over the immunity interpretation of non-domination. I show that whilst these solutions accord well with many important republican tenets, they have other implications that contradict known republican positions. In particular, I show there is both room and a need for retributivism within republicanism. (shrink)

We give a model for iterated belief change in multi-agent systems. The formal tool we use for this is a combination of modal and dynamic logic. Two core notions in our model are the expansion of the knowledge and beliefs of an agent, and the processing of new information. An expansion is defined as the change in the knowledge and beliefs of an agent when it decides to believe an incoming formula while holding on to its current propositional beliefs. To (...) prevent our agents from forming inconsistent beliefs they do not expand with every piece of information they receive. Instead, our agents remember their original beliefs and every piece of information they receive. After every receipt of information they decide which subset of the received information should be incorporated into their original beliefs. This procedure is called the processing of new information. We show that our model of belief update behaves in an intuitive way and that it is not sensitive to criticism on comparable models. (shrink)

Ernest Mandel theorised the capitalist world economy as an articulated system of capitalist, semi-capitalist and precapitalist relations of production, linked to each other by capitalist relations of exchange and domination by the capitalist world market. This seems to be an interesting starting point for an historically well-founded theory, building on and going beyond Marx's work, of the worldwide expansion of the capitalist mode of production from its origins to the present. In his attempt to formulate his theory, Mandel did not (...) succeed in resolving all difficulties, however. His main works – Marxist Economic Theory and Late Capitalism – show a number of dangling loose ends. The central question is whether these loose ends are merely technical difficulties or whether they reveal fatal flaws in the theory as a whole. In order to come a step closer to answering this question, a conference was organised in Amsterdam, November 2003. This introduction formulates the five, closely interrelated issues that were highlighted at this conference. (shrink)

Different methods have been developed to address ethical issues during research. Most of these methods were developed at universities. In this article ethical parallel research within a Research and Technology Organization is described. Within a European project about perceived security, CPSI, the ethical issues were identified by ethicists cooperating in the project. The project CPSI was aimed at developing a research method that can be used by (local) government to monitor or assess perceived and actual security. Together with the researchers (...) a way was sought to address the ethical issues. Several issues could be addressed by choices with regard to the design of the validation study, in this case a survey. The ethical and legal reasons that were relevant for choices in the design of the validation study were made an integral part of these decisions. Some issues were already identified during the writing of the proposal others were only identified during the research. Participating in the research gave the ethicists access to all relevant information. It made it possible to address the ethical issues when they became relevant. Ethical reasons were part of some of the discussions on research method. It proved possible to address most ethical issues satisfactorily during the research project. (shrink)

New and Emerging Science and Technology (NEST) based innovations, e.g. in the field of Life Sciences or Nanotechnology, frequently raise societal and political concerns. To address these concerns NEST researchers are expected to deploy socially responsible R&D practices. This requires researchers to integrate social and ethical aspects (SEAs) in their daily work. Many methods can facilitate such integration. Still, why and how researchers should and could use SEAs remains largely unclear. In this paper we aim to relate motivations for NEST (...) researchers to include SEAs in their work, and the requirements to establish such integration from their perspectives, to existing approaches that can be used to establish integration of SEAs in the daily work of these NEST researchers. Based on our analyses, we argue that for the successful integration of SEAs in R&D practice, collaborative approaches between researchers and scholars from the social sciences and humanities seem the most successful. The only way to explore whether that is in fact the case, is by embarking on collaborative research endeavours. (shrink)

A systematic study of testimony rooted in contemporary continental philosophy and drawing on literary case studies. From analytic epistemology to gender theory, testimony is a major topic in philosophy today. Yet, one distinctive approach to testimony has not been fully appreciated: the recent history of contemporary continental philosophy offers a rich source for another approach to testimony. In this book, Gert-Jan van der Heiden argues that a continental philosophy of testimony can be developed that is guided by those forms of (...) bearing witness that attest to limit experiences of human existence, in which the human is rendered mute, speechless, or robbed of a common understanding. In the first part, Van der Heiden explores this sense of testimony in a reading of several literary texts, ranging from Plato’s literary inventions to those of Kierkegaard, Melville, Soucy, and Mortier. In the second part, based on the orientation offered by the literary experiments, Van der Heiden offers a more systematic account of testimony in which he distinguishes and analyzes four basic elements of testimony. In the third part, he shows what this analysis implies for the question of the truth and the truthfulness of testimony. In his discussion with philosophers such as Heidegger, Derrida, Lyotard, Agamben, Foucault, Ricoeur, and Badiou, Van der Heiden also provides an overview of how the problem of testimony emerges in a number of thinkers pivotal to twentieth- and twenty-first-century thought. “The Voice of Misery is a special book. Van der Heiden has presented an argument that is poised to challenge discourse in analytic philosophy, reshape approaches in continental philosophy, and give new orientation to interdisciplinary research in continental philosophy and literary theory. The book will find a large readership across the discipline of philosophy and in several areas of the humanities.” — Theodore George, author of Tragedies of Spirit: Tracing Finitude in Hegel’s Phenomenology.

Thanks to the exchange of arguments, groups outperform individuals on some tasks, such as solving logical problems. However, these results stem from experiments conducted among Westerners and they could be due to cultural particularities such as tolerance of contradiction and approval of public debate. Other cultures, collectivistic cultures in particular, are said to frown on argumentation. Moreover, some influential intellectual movements, such as Confucianism, disapprove of argumentation. In two experiments, the hypothesis that Easterners might not share the benefits of argumentation (...) was tested. In Experiment 1, Japanese participants had to solve a standard logical problem individually and then in groups. They performed significantly better in groups. In Experiment 2, Japanese participants had to estimate the weight of various animals. They did so individually, then after learning of another participant's estimates, then after discussing these estimates with the other participant, and then indi.. (shrink)

Policy makers call upon researchers from the natural and social sciences to collaborate for the responsible development and deployment of innovations. Collaborations are projected to enhance both the technical quality of innovations, and the extent to which relevant social and ethical considerations are integrated into their development. This could make these innovations more socially robust and responsible, particularly in new and emerging scientific and technological fields, such as synthetic biology and nanotechnology. Some researchers from both fields have embarked on collaborative (...) research activities, using various Technology Assessment approaches and Socio-Technical Integration Research activities such as Midstream Modulation. Still, practical experience of collaborations in industry is limited, while much may be expected from industry in terms of socially responsible innovation development. Experience in and guidelines on how to set up and manage such collaborations are not easily available. Having carried out various collaborative research activities in industry ourselves, we aim to share in this paper our experiences in setting up and working in such collaborations. We highlight the possibilities and boundaries in setting up and managing collaborations, and discuss how we have experienced the emergence of ‘collaborative spaces.’ Hopefully our findings can facilitate and encourage others to set up collaborative research endeavours.

We performed an EEG graph analysis on data from 31 typical readers and 24 dyslexics, recorded while they were engaged in an audiovisual task and during resting-state. The task simulates reading acquisition as participants learned new letter-sound mappings via feedback. EEG data was filtered for the delta, theta, alpha, and beta bands. We computed the Phase Lag Index to provide an estimate of the functional connectivity between all pairs of electrodes per band. Then, networks were constructed using a Minimum Spanning (...) Tree, a unique sub-graph connecting all nodes without loops, aimed at minimizing bias in between groups and conditions comparisons. Both groups showed a comparable accuracy increase during task blocks, indicating that they correctly learned the new associations. The EEG results revealed lower task-specific theta connectivity, and lower theta degree correlation over both rest and task recordings, indicating less network integration in dyslexics compared to typical readers. This pattern suggests a role of theta oscillations in dyslexia and may reflect differences in task engagement between the groups, although robust correlations between MST metrics and performance indices were lacking.

OBJECTIVES: To identify the factors that influence the assessment of reported cases of physician-assisted death by members of the public prosecution. DESIGN/SETTING: At the beginning of 1996, during verbal interviews, 12 short case-descriptions were presented to a representative group of 47 members of the public prosecution in the Netherlands. RESULTS: Assessment varied considerably between respondents. Some respondents made more "lenient" assessments than others. Characteristics of the respondents, such as function, personal-life philosophy and age, were not related to the assessment. Case (...) characteristics, i.e. the presence of an explicit request, life expectancy and the type of suffering, strongly influenced the assessment. Of these characteristics, the presence or absence of an explicit request was the most important determinant of the decision whether or not to hold an inquest. CONCLUSIONS: Although the presence of an explicit request, life expectancy and the type of suffering each influenced the assessment, each individual assessment was dependent on the assessor. The resulting danger of legal inequality and legal uncertainty, particularly in complicated cases, should be kept to a minimum by the introduction of some form of protocol and consultation in doubtful or boundary cases. The notification procedure already promotes a certain degree of uniformity in the prosecution policy. (shrink)

In this paper, we introduce the methodology and techniques of meta-argumentation to model argumentation. The methodology of meta-argumentation instantiates Dung’s abstract argumentation theory with an extended argumentation theory, and is thus based on a combination of the methodology of instantiating abstract arguments, and the methodology of extending Dung’s basic argumentation frameworks with other relations among abstract arguments. The technique of meta-argumentation applies Dung’s theory of abstract argumentation to itself, by instantiating Dung’s abstract arguments with meta-arguments using a technique called flattening. (...) We characterize the domain of instantiation using a representation technique based on soundness and completeness. Finally, we distinguish among various instantiations using the technique of specification languages. (shrink)
