This article reports on the development and teaching of compulsory courses on ethics and engineering at Delft University of Technology (DUT). Attention is paid to the teaching goals, the educational setup and methods, the contents of the courses, involvement of staff from engineering schools, experiences to date, and challenges for the future. The choices made with respect to the development and teaching of the courses are placed within the European and Dutch context and are compared and contrasted with the American (...) situation and experiences.

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)

Two points are made on the basis of (mainly) the cross-cultural psychological record. The first is that cross-cultural data indicate at least weak, nontrivial constraints on colour classification. The second is that exceptions to cross-cultural regularities as described by Saunders & van Brakel are compatible with the view that constraints on colour categories are probabilistic rather than deterministic.

A guide for organizational and social research in business studies and the social sciences, providing a clear framework for research design and methodology. It will be an invaluable tool for academics, researchers, and graduate students across the social sciences concerned with rigorous and relevant research in the contemporary world.

A meta-analysis of 190 cross-cultural emotion studies, published between 1967 and 2000, was performed to examine (1) to what extent reported cross-cultural differences in emotion variables could be regarded as valid (substantive factors) or as method-related (statistical artefacts, cultural bias), and (2) which country characteristics could explain valid cross-cultural differences in emotion. The relative contribution of substantive and method-related factors at sample, study, and country level was investigated and country-level explanations for differences in emotions were tested. Results indicate that a (...) correction for statistical artefacts and method-related factors reduced the observed cross-cultural effect sizes considerably. After controlling for valence (positive vs. negative emotions) and kind of study (self-report vs. recognition studies), the remaining cross-cultural variance was associated with subsistence mode, political system, values, and religiosity. Values explained more variance than did ecological or sociopolitical variables. It was concluded that both method-related factors (13.8% of variance explained) and culture-level factors (27.9% of variance explained) underlie observed cross-cultural differences. (shrink)

Previous research has yielded inconsistent findings concerning the relationship between envy and schadenfreude. Three studies examined whether the distinction between benign and malicious envy can resolve this inconsistency. We found that malicious envy is related to schadenfreude, while benign envy is not. This result held both in the Netherlands where benign and malicious envy are indicated by separate words (Study 1: Sample A, N = 139; Sample B, N = 150), and in the USA where a single word is used (...) to denote both types (Study 2, N = 180; Study 3, N = 349). Moreover, the effect of malicious envy on schadenfreude was independent of other antecedents of schadenfreude (such as feelings of inferiority, disliking the target person, anger, and perceived deservedness). These findings improve our understanding of the antecedents of schadenfreude and help reconcile seemingly contradictory findings on the relationship between envy and schadenfreude. (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 systematic review aimed to provide an overview of earlier research on the relationships between age conceptualizations and indicators of employability. We have conducted a systematic literature search using PsycINFO, Academic Search Premier, Business Source Complete, CINAHL, ERIC, MEDLINE, and Science Direct. Two raters evaluated the articles and subsequently distinguished k = 41 studies that met the inclusion criteria for this systematic review. Our review revealed that many researchers adopted different operationalizations to measure employability. Moreover, most studies included calendar age (...) as indicator of aging at work, and were based on a cross-sectional design. Based on the Standardized Index of Convergence method, different types of evidence were found for the relationships between age and the employability measures. For relationships between psychosocial age and lifespan age, on the one hand, and employability measures, on the other hand, too few studies were found to draw conclusions. Yet, for relationships between calendar age and labor market-based measures strong consistent negative relationships were found across the studies, and moderately strong positive relationships were found for functional age and labor market- based measures. For organizational age and both competence-based as well as labor market-based measures moderately strong negative relationships were found. We discuss the implications of these results and propose a research agenda for future studies. (shrink)

This article examines the effects of strategic and substantive news on political cynicism, turnout intention and voter uncertainty, drawing on two experiments. We found that among less politically knowledgeable citizens, all news mobilizes, but strategic news also induces cynicism. For the more knowledgeable citizens, we found that the combination of strategic and substantive news yields slightly less cynicism and that substantive news makes these citizens reconsider their voting choice. Overall, we only found favorable or neutral effects among the more knowledgeable, (...) while we found both favorable and unfavorable effects among the less knowledgeable. The implications for news effects research are discussed. (shrink)

It often appears that leading politicians in Belgium consider the results of the municipal elections in the light of national polities. They stick to the thesis that the municipal poll-results, at least in the bigger towns, are more and more influenced by the constellation of the nation's politics.Is it really so that the municipal elections indicate the hearings of the national political situation? Can one draw conclusions from the results of these elections as if they were national ones? And can (...) one,any how, compare municipal to parliamentary elections? By comparison of the results of municipal elections 1964 and of parliamentary elections 1965 it was checked which shifts in party-choice havehappened during this short period of eight months. If no oscillations, or only a few, were detected between both elections, one could conclude that the municipal elections 1964 indicated indeed the hearings of the parliamentary elections 1965.Successively, the national and provincial results of these elections were compared and the party-shifts on national and provincial level were calculated.To make a relevant comparison between the election-results on a lower level, a comparable basic unity had to be found. As there were no municipal data available at parliamentary elections on one side, andonly municipal results at the municipal elections on the other side, the least possible unity for which parliamentary election-results are known, the electoral canton namely, was chosen as a comparison-basis. For that purpose however the results per party had to be additioned in all municipalities belonging to one canton.Part of the electoral cantons was unfit for use as comparison-material for two reasons : the highly varied and often strongly local-coloured political party-structure on one hand, the big number of municipalitieswithout elections on the other hand. So we were bound to make a choice out of 212 electoral cantons. Finally the cantons with a maximum of 4 municipalities were chosen, which limited the number of cantons to 28. These cantons were classified by degree of urbanisation according to the typology of W. Van Waelvelde and H. Van der Haegen.In that classification the percentages of votes in favour of the political parties, at the occasion of these elections, were tabulated and compared.The participating parties and lists were grouped as much as possible around the traditional parties to which they were most related. So we distinguish in Flanders : CVP, BSP, PVV, VU, CPB and other parties ;in the Walloon region: PSC, PSB, PLP PCB, French-speaking lists and other parties.For this analysis we also thought it was relevant to control separately the shifts of the electoral corps in the Flemish, the Walloon and the Brussels cantons. These shifts were then specified according to thedegree of urbanisation.To measure the size of the party-shifts for these elections, the external election-shift standard was calculated for the chosen Flemish, Walloon and Brussels cantons, with a special attention for the degree of urbanisation. Finally we examined which attitude was assumed by the government, the governmental and the opposition parties, in relation to the results of the municipal 1964 elections.It appeared that some notable party-shifts had been realized during the short period between the municipal elections of 1964 and the legislative elections of 1965. In general, a certain polarization has taken place due to a centrifugal vote-shift to the left and still more to the right. The direction of vote-shifts, which had shown at the municipal elections of 1964, was affirmed at the legislative elections of 1965 and for some parties, CVP and PVV namely, it was even accentuated. The parallelism between both elections in relation to the direction of the vote-shifts did not mean however that the size of these shifts was the same everywhere. The image of the shifts was different according to linguistic region and degree of urbanisation.The analysis of the urbanisation-degree showed that the level of oscillations grew higher as the urbanisation-degree grew lower. Seen per linguistic region, the largest shifts had taken place in the Walloon cantons. According to the calculations of the electoral shift standards during the period 1964-1965, the lowest oscillations were noted in the Flemish and Brussels cantons, i.e. the voting-behaviour of the big agglomerations during the municipal elections of 1964 were the closest to the national electoral pattern. Seen that way they were, up to a certain degree, a value-measure for the general policy.Finally the remark should be made that the limitation to the two above-mentioned elections does not allow any generalization of the obtained conclusions. The short period between those elections was itself an exceptional situation which may have been of influence on the results of the comparisons. (shrink)

Background: Issues concerning legislation and regulation with respect to the role of nurses in euthanasia and physician-assisted suicide gave the Minister for Health reason to commission a study of the role of nurses in medical end-of-life decisions in hospitals, home care and nursing homes.Aim: This paper reports the findings of a study of the role of nurses in euthanasia and physician-assisted suicide, conducted as part of a study of the role of nurses in medical end-of-life decisions. The findings for hospitals, (...) home care and nursing homes are described and compared.Method: A questionnaire was sent to 1509 nurses, employed in 73 hospitals, 55 home care organisations and 63 nursing homes. 1179 responses were suitable for analysis. The questionnaire was pilot-tested among 106 nurses, with a response rate of 85%.Results: In 37.0% of cases, the nurse was the first person with whom patients discussed their request for euthanasia or physician-assisted suicide. Consultation between physicians and nurses during the decision-making process took place quite often in hospitals and nursing homes and less frequently in home care situations . In some cases , nurses administered the euthanatics.Conclusions: The results show substantial differences between the intramural sector and the extramural sector , which are probably linked to the organisational structure of the institutions. Consultation between physicians and nurses during the decision-making process needs improvement, particularly in home care. Some nurses had administered euthanatics, although this task is by law exclusively reserved to physicians. (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)

This article reports the findings of a study into the role of Dutch nurses in the alleviation of pain and symptoms with a life-shortening intention, conducted as part of a study into the role of nurses in medical end-of-life decisions. A questionnaire survey was carried out using a population of 1509 nurses who were employed in hospitals, home care organizations and nursing homes. The response rate was 82.0%; 78.1% (1179) were suitable for analysis. The results show that in about half (...) of the cases (55.8%) nurses were involved in the decision making by the physician and that nurses were frequently (81.5%) involved in administering the medication. The authors' conclusion is that alleviation of pain and symptoms with a life-shortening intention represents a `grey' area, in which physicians and nurses act on the basis of personal ethical norms rather than legal rules, professional guidelines or shared moral values.
