This paper canvasses recent arguments in favor of commercial markets in human transplant kidneys, raising objections to those arguments on grounds of the role of injustice, exploitation, and coercion in compromising the autonomy of those most likely to sell a kidney, namely, the least well off members of society.

There has been an increase in recent years in the use of empirical methods in healthcare ethics. Appeals to empirical data cannot answer moral questions, but insights into the knowledge, attitudes, experience, preferences and practice of interested parties can play an important part in the development of healthcare ethics. In particular, while we may establish a general ethical principle to provide explanatory and normative guidance for healthcare professionals, the interpretation and application of such general principles to actual practice still requires (...) interpretation and judgement. And many situations in healthcare practice are complex and may involve a variety of principles, each of which may conflict with the others. Simple surveys or interview studies may not be sufficient if we wish to develop a nuanced approach to ethical practice that can be set out in guidelines, codes or directives. We do not resolve moral questions by plebiscite. In this paper, the authors argue for the use of consensus methods to develop shared understanding of ethical practice, and they argue further for the combination of the Delphi method with the use of vignettes to illustrate the kind of situations that may occur in practice. They develop their argument in part by reference to their experience of using this approach in their recent research. (shrink)

L’identité juive de Jésus est un fait avéré. Dans le christianisme cependant, l’ignorance de la variété des courants d’idée dans le judaïsme au début de notre ère a conduit certains à placer l’enseignement de Jésus entièrement en marge ou même en dehors du judaïsme et à tirer argument de l’originalité de son message contre son origine juive. De même, certains courants de type monophysite ont sous-estimé, voire nié l’enracinement humain de Jésus et sa « racination » juive . Au sein (...) de milieux « post-chrétiens », à l’antisémitisme latent ou affiché, l’identité juive de Jésus fait scandale. Dans le judaïsme, parler de Jésus reste difficile, et tout messianisme fait peur. Depuis la deuxième moitié du XIXe s., toutefois, des savants juifs ont beaucoup fait pour réintroduire Jésus dans l’histoire du judaïsme. Les autorités de l’Église catholique et d’autres Églises ont rappelé sans détour la judéité de Jésus. L’humanité de Jésus et son enracinement historique ont retrouvé leur place dans la théologie, sans préjudice pour l’intégrité de la foi chrétienne. Il faut mentionner également les recherches sur les origines juives du christianisme. L’affirmation de l’identité juive de Jésus par les chrétiens et par les juifs est l’une des pierres de touche de la vérité des relations et du dialogue entre eux aujourd’hui. (shrink)

The aim of the paper is to show the philosophy of G. Marcel as a personally expe_rienced encounter with the most burning problems of our times. In his view the philosophical reflection is discovering of the meaningful order of the world. Attention is paid also to the influence, of G. Marcel's work on the thinking of Slovak and Czech philosophers.

This paper discusses the utilization of pilots' physiological indications such as electroencephalographic signals, ocular parameters, and pilot performance-based quantitative metrics to estimate cognitive workload. The study aims to derive a non-invasive technique to estimate pilot's cognitive workload and study their correlation with standard physiological parameters. Initially, we conducted a set of user trials using well-established psychometric tests for evaluating the effectiveness of pupil and gaze-based ocular metrics for estimating cognitive workload at different levels of task difficulty and lighting conditions. Later, (...) we conducted user trials with the NALSim flight simulator using a business class Learjet aircraft model. We analyzed participants' ocular parameters, power levels of different EEG frequency bands, and flight parameters for estimating variations in cognitive workload. Results indicate that introduction of secondary task increases pilot's cognitive workload significantly. The beta frequency band of EEG, nearest neighborhood index specifying distribution of gaze fixation, L1 Norm of power spectral density of pupil diameter, and the duty cycle metric indicated variations in cognitive workload.
