Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

Quelle différence y a-t-il entre des règles de droit et des ordres appuyés de menaces? Qu'est-ce qu'une obligation juridique et en quoi se trouve-t-elle apparentée à une obligation morale? Quelle est la nature des règles et dans quelle mesure le droit consiste-t-il en des règles? Qu'est-ce que la justice et en quoi diffère-t-elle du reste de la morale?Au cours d'une discussion approfondie et séparée de ces problèmes récurrents, l'auteur relève une série d'éléments d'une importance essentielle pour la compréhension du droit, (...) et réalise un nouveau départ dans la théorie du droit. L'ouvrage comporte une nouvelle analyse des notions de validité juridique, de souveraineté, et de fondement d'un système juridique, un nouvel examen du droit naturel et du positivisme juridique, une discussion originale des limites du formalisme dans l'élaboration de la décision judiciaire, et un examen de la nature du droit international.Le texte est complété par des notes bibliographiques détaillées et la discussion de thèses émises par des auteurs contemporains et plus anciens. Cette deuxième édition s'accompagne en outre d'une postface posthume, publiée sous la responsabilité de P.A. Bulloch et J. Raz. (shrink)

Current theory-of-mind research faces the challenge of reconciling two sets of seemingly incompatible findings: Whereas children come to solve explicit verbal false belief tasks from around 4years of age, recent studies with various less explicit measures such as looking time, anticipatory looking, and spontaneous behavior suggest that even infants can succeed on some FB tasks. In response to this tension, two-systems theories propose to distinguish between an early-developing system, tracking simple forms of mental states, and a later-developing system, based on (...) fully developed concepts of belief and other propositional attitudes. One prediction of such theories is that the early-developing system has signature limits concerning aspectuality. We tested this prediction in two experiments. The first experiment showed that 2- and 3-year-olds take into account a protagonist's true or false belief about the location of an object in their active helping behavior. In contrast, toddlers' helping behavior did not differentiate between true and false belief conditions when the protagonist's belief essentially involved aspectuality. Experiment 2 replicated these findings with a more stringent method designed to rule out more parsimonious explanations. Taken together, the current findings are compatible with the possibility that early theory-of-mind reasoning is subject to signature limits as predicted by the two-systems account. (shrink)

In this paper we examine to what extent the lengths of the links in an animated articulated figure can be changed without the viewer being aware of the change. This is investigated in terms of a framework that emphasizes the role of attention in visual perception. We conducted a set of five experiments to establish bounds for the sen-sitivity to changes in length as a function of several parameters and the amount of attention available. We found that while length changes (...) of 3% can be perceived when the relevant links are given full attention, changes of over 20% can go unnoticed when attention is not focused in this way. These results provide general guidelines for algorithms that produce or process character motion data and also bring to light some of the potential gains that stand to be achieved with attention-based algorithms.

Organizations such as the EU High-Level Expert Group on AI and the IEEE have recently formulated ethical principles and (moral) values that should be adhered to in the design and deployment of artificial intelligence (AI). These include respect for autonomy, non-maleficence, fairness, transparency, explainability, and accountability. But how can we ensure and verify that an AI system actually respects these values? To help answer this question, I propose an account for determining when an AI system can be said to embody (...) certain values. This account understands embodied values as the result of design activities intended to embed those values in such systems. AI systems are here understood as a special kind of sociotechnical system that, like traditional sociotechnical systems, are composed of technical artifacts, human agents, and institutions but—in addition—contain artificial agents and certain technical norms that regulate interactions between artificial agents and other elements of the system. The specific challenges and opportunities of embedding values in AI systems are discussed, and some lessons for better embedding values in AI systems are drawn. (shrink)

A series of experiments was performed in which subjects indicated whether two four-dot patterns were the same, although possibly viewed from different directions, or different, paired at random. Analyses of responses times and error rates suggest that the subjects' performance in this affine matching task is based on non-accidental properties such as convexity, parallelism, collinearity, and proximity, rather than on real affine invariants such as the ratio of triangular areas.

In Printing Spinoza Jeroen van de Ven systematically examines all seventeenth-century printed editions of Spinoza's writings, published between 1663 and 1694, as well as their variant 'issues'. In focus are Spinoza's 1663 adumbration of René Descartes's 'Principles of Philosophy' with his own 'Metaphysical Thoughts', the 'Theological-Political Treatise' (1670), and the posthumous writings (1677), including the famously-known 'Ethics'. Van de Ven's descriptive bibliography studies, contextualizes, and records all aspects of the publication history of Spinoza's writings from manuscript to print and assesses (...) their immediate reception. It discusses the printed books' codicology, philology, typographical and textual relationships, illustration programmes, as well as their dissemination in early Enlightenment Europe, in view of the physical aspects of 1,246 extant copies and their provenance.

Direct-to-consumer advertising (DTCA) of prescription drugs has been a heavily contested issue over the past decade, touching on several issues of responsibility facing the pharmaceutical industry. Much research has been conducted on DTCA, but hardly any studies have discussed this topic from a corporate social responsibility (CSR) perspective. In this article, we use several elements of CSR, emphasising consumer autonomy and safety, to analyse differences in DTCA practices within two different policy contexts, the United States of America and the European (...) Union (EU). Doing so results in an alternative analysis of the struggle between proponents and opponents of DTCA from a CSR perspective, adding an alternative view on this debate. (shrink)

We assessed how synchronous speech listening and lipreading affects speech recognition in acoustic noise. In simple audiovisual perceptual tasks, inverse effectiveness is often observed, which holds that the weaker the unimodal stimuli, or the poorer their signal-to-noise ratio, the stronger the audiovisual benefit. So far, however, inverse effectiveness has not been demonstrated for complex audiovisual speech stimuli. Here we assess whether this multisensory integration effect can also be observed for the recognizability of spoken words. To that end, we presented audiovisual (...) sentences to 18 native-Dutch normal-hearing participants, who had to identify the spoken words from a finite list. Speech-recognition performance was determined for auditory-only, visual-only (lipreading) and auditory-visual conditions. To modulate acoustic task difficulty, we systematically varied the auditory signal-to-noise ratio. In line with a commonly-observed multisensory enhancement on speech recognition, audiovisual words were more easily recognized than auditory-only words (recognition thresholds of -15 dB and -12 dB, respectively). We here show that the difficulty of recognizing a particular word, either acoustically or visually, determines the occurrence of inverse effectiveness in audiovisual word integration. Thus, words that are better heard or recognized through lipreading, benefit less from bimodal presentation. Audiovisual performance at the lowest acoustic signal-to-noise ratios (45%) fell below the visual recognition rates (60%), reflecting an actual deterioration of lipreading in the presence of excessive acoustic noise. This suggests that the brain may adopt a strategy in which attention has to be divided between listening and lipreading. (shrink)

The authors explore whether the need for ethical reflection on the part of designing engineers is dependent on the type of design process. They use Vincenti's distinction between normal and radical design and different levels of design hierarchy. These two dimensions are coupled with the concept of ill-structured problems, which are problems in which possible solutions cannot be ordered on a scale from better to worse. Design problems are better structured at lower hierarchical levels and in cases of normal design. (...) Better structured design problems require less ethical reflection on the part of designing engineers if such situations are characterized by the existence of generally accepted normative frameworks. Engineers could then deal with moral problems within the bounds of such frameworks and without the need for further reflection. On the basis of a number of empirical cases, the authors explore whether these ideas hold water. They discuss four cases ranging from a high-level radical design process to a low-level normal design process. (shrink)

Background Speech understanding may rely not only on auditory, but also on visual information. Non-invasive functional neuroimaging techniques can expose the neural processes underlying the integration of multisensory processes required for speech understanding in humans. Nevertheless, noise (from fMRI) limits the usefulness in auditory experiments, and electromagnetic artefacts caused by electronic implants worn by subjects can severely distort the scans (EEG, fMRI). Therefore, we assessed audio-visual activation of temporal cortex with a silent, optical neuroimaging technique: functional near-infrared spectroscopy (fNIRS). Methods (...) We studied temporal cortical activation as represented by concentration changes of oxy- and deoxy-hemoglobin in four, easy-to-apply fNIRS optical channels of 33 normal-hearing adult subjects and 5 post-lingually deaf cochlear implant (CI) users in response to supra-threshold unisensory auditory and visual, as well as to congruent auditory-visual speech stimuli. Results Activation effects were not visible from single fNIRS channels. However, by discounting physiological noise through reference channel subtraction, auditory, visual and audiovisual speech stimuli evoked concentration changes for all sensory modalities in both cohorts (p<0.001). Auditory stimulation evoked larger concentration changes than visual stimuli (p<0.001). A saturation effect was observed for the audiovisual condition. Conclusions Physiological, systemic noise can be removed from fNIRS signals by reference channel subtraction. The observed multisensory enhancement of an auditory cortical channel can be plausibly described by a simple addition of the auditory and visual signals with saturation. (shrink)

This paper aims at contributing to a research agenda in engineering ethics by exploring the ethical aspects of engineering design processes. A number of ethically relevant topics with respect to design processes are identified. These topics could be a subject for further research in the field of engineering ethics. In addition, it is argued that the way design processes are now organised and should be organised from a normative point of view is an important topic for research.
