In this paper, we consider choice functions that are unanimous, anonymous, symmetric, and group strategy-proof and consider domains that are single-peaked on some tree. We prove the following three results in this setting. First, there exists a unanimous, anonymous, symmetric, and group strategy-proof choice function on a path-connected domain if and only if the domain is single-peaked on a tree and the number of agents is odd. Second, a choice function is unanimous, anonymous, symmetric, and group strategy-proof on a single-peaked (...) domain on a tree if and only if it is the pairwise majority rule and the number of agents is odd. Third, there exists a unanimous, anonymous, symmetric, and strategy-proof choice function on a strongly path-connected domain if and only if the domain is single-peaked on a tree and the number of agents is odd. As a corollary of these results, we obtain that there exists no unanimous, anonymous, symmetric, and group strategy-proof choice function on a path-connected domain if the number of agents is even.

Kritische bijdragen over ideologisch gekleurde vormen van westerse culturele antropologie.

My main purpose in this article is to establish the meaning of a ‘good death’ when death is self-chosen. I will take as my point of departure the new notion of ‘self-euthanasia’ and the corresponding practice that has evolved in the Netherlands in recent years. Both physician-euthanasia and self-euthanasia refer to an ideal process of a good death, the first being ultimately the physician's responsibility, while the second is definitely the responsibility of the individual choosing to die. However, if we (...) also accept the existence of a fundamental moral difference between ending another person's life and ending your own life, and if we accept this moral difference to be also relevant to the normatively laden good death, then this difference represents a strong reason for preferring self-euthanasia to physician-euthanasia.

Theorie en de praktijk, geënt op filosofieën en mediatatie-methoden uit Zen-kloosters en Hindoe-ashrams.

Social rights were to be the completion of the citizenship status of all members within a political community. Through a variety of causes the development of these rights has been arrested. The article sketches some of the origins of the present predicament of rights and citizenship. The article is informed by the hope that the arguments it puts forward may contribute to a renewed discussion on the necessity and promises of an EU form of citizenship that is worth instituting and (...) emulating.

The conducive economy challenges both the conceptual foundations and the practices of present-day economies. In the Netherlands, a few initiatives during the 1980s and early 1990s looked promising, in particular, as these initiatives focused on work quality as one major precondition for reducing disability and enhancing labor participation. Prospects are less bright today. Ever larger slices of governmental monetary, financial, economic, and social policies become market oriented, as distinct from conducivity oriented. The instrument of the covenant, nonetheless, may prove worthwhile (...) in further promoting the banner of work quality. (shrink)

ABSTRACT Amartya Sen’s capability approach is often used in disability research as a normative framework for describing and evaluating the well-being of people with disabilities. Nevertheless, recently, the possibility of going beyond description to the use of the capability approach as an explanatory tool has been raised. However, to allow the use of the capability approach in this way requires grounding it in an appropriate research paradigm. In this paper, critical realism is adopted for this purpose. It is argued that (...) critical realism can provide the ontology needed to justify finding explanations for the way that people with disabilities achieve their valued capabilities. The assumption here is that there are real, emergent structures and mechanisms that underlie empirical capabilities; and that these structures and mechanisms are related to people’s agency, as described by critical realism’s conception of the relationship between structure and agency.

Miracle narratives are an essential part of nearly all religious traditions. The importance of miracles also applies to Christianity. The Gospels record thirty-five miracles that Jesus is said to have performed, including twenty-three miraculous healings and nine nature miracles (for example, stilling a storm and turning water into wine). At the heart of Christian faith lies the story of Jesus' resurrection from the dead. However, the factuality of these events has been increasingly problematised, especially since the period of the Enlightenment. (...) In this study, it is argued that the current debate between science-oriented critics of miracles and their religious opponents focuses predominantly on the question of factuality and evidence at the loss of the religious meaning of miracles. The suggestion that science and religion would be opposite approaches is denied in a proposal of a balanced hermeneutical approach of miracles that does justice to scientific findings, religious texts and experience.

Logicians treat assertions as true, believed or merely hypothesized sentences. The reasoner who uses them, however, is the sole referee who can validate their truth, their aptness to describe an actual situation, their strength (as beliefs) or the relevance of their use in the current logical context. Moreover, the reasoner actively counts on these factors, as part of the reasoning process itself, and should normally be capable, when asked to do so, to assign consistently relative strengths to the assertions used. (...) The paper assumes, first, that assertions have -each- an associated, measurable strength, and that, second, this strength has significant -and measurable- effects on the truth of the sentences, the validity of the conclusion and the soundness of the reasoning. The concepts and formulas required for this are explored, and a semantics and proof theory for a sentential calculus of assertions are proposed as a natural extension of ordinary two-valued reasoning. The resulting theory, though reminiscent of Probability,is autonomous, self-contained and of a purely logical nature. (shrink)

For further development of organic agriculture, it will become increasingly essential to integrate experienced innovative practitioners in research projects. The characteristics of this process of co-learning have been transformed into a research approach, theoretically conceptualized as “experiential science” (Baars 2007 , Baars and Baars 2007 ). The approach integrates social sciences, natural sciences, and human sciences. It is derived from action research and belongs to the wider field of transdiscliplinary research. In a dialogue-based culture of equality and mutual exchange the (...) principal of a “bottom-up” experiential learning process can be stimulated and fully reflective. It provides an opportunity to develop organic agriculture as multiple best-practices based on transdisciplinary projects, cases studies, and case series. The aim of the article is to describe the methodological characteristics and the theoretical and practical potential of experiential science for research in and development of organic farming. Three characteristic projects are outlined to illustrate the main elements of the methodology: the retrospective reflection on intuitive and experiential knowledge held by farmers; the knowledge derived from on-farm experimentation; the exchange of knowledge and experiences between farming pioneers within a “masterclass” setting. The study concludes that experiential science offers an important philosophical reconciliation process whereby a synthesis of different approaches to research becomes possible in solving real-life problems: quantitative and qualitative, subjective and objective, reductionistic and holistic, practice and science. Recognizing that there are multiple elements contributing to the process of acquiring knowledge, experiential science draws on a broad field of scientific methods thereby integrating the hermeneutic approach of social sciences and the Humanities with the established methods of contemporary natural science.

Inleiding tot de fenomenologische methode van werkelijkheidsbenadering.

The article is focused on the profession of faith and the oath of fidelity, as has been formulated in 1989 by the Congregation of Faith. Catholic clergy as well as Catholic theologians are obliged to profess the Catholic faith and to take the oath before assuming an ecclesiastical office or function. The analyses and reflections are from the point of view of canon law. A retro prospective view makes clear that the profession and oath belong to the disciplinary tradition of (...) the Church. The Council of Trent offered the first more or less systematic regulation. The profession and the oath intend to guarantee that ecclesiastical ministers and Catholic theologians are in full communion with the Catholic Church. The three additional paragraphs of the profession and the text of the oath are condensed formulations of canons of the Code of Canon Law. In that way the profession and the oath are indirectly a part of the disciplinary corps of the Code. Their canonical disciplinairy significance has been investigated. The article ends with some general conclusions and considerations. (shrink)
