A continuoxis t- norm is a continuous map * from [0, 1]² into [0,1] such that is a commutative totally ordered monoid. Since the natural ordering on [0,1] is a complete lattice ordering, each continuous t-norm induces naturally a residuation → and becomes a commutative naturally ordered residuated monoid, also called a hoop. The variety of basic hoops is precisely the variety generated by all algebras, where * is a continuous t-norm. In this paper we investigate the structure of the (...) variety of basic hoops and some of its subvarieties. In particular we provide a complete description of the finite subdirectly irreducible basic hoops, and we show that the variety of basic hoops is generated as a quasivariety by its finite algebras. We extend these results to Hájek's BL-algebras, and we give an alternative proof of the fact that the variety of BL-algebras is generated by all algebras arising from continuous t-norms on [ 0,1] and their residua. The last part of the paper is devoted to the investigation of the subreducts of BL- algebras, of Gödel algebras and of product algebras. (shrink)

A simplified definition of point local clocks and the relationship between an inertial reference frame and a class of such clocks, at rest with respect to each other, are used for an algebraic determination of the geometry of Minkowski's space-time on the set of point events. The group of all automorphisms that preserve the time ordering induced by the set of all equivalent local clocks is shown to be generated by the inhomogeneous orthochronous Lorentz group and dilatations, consistently with a (...) well-known result of E. C. Zeeman. The existence of a universal limit velocity and of an invariant clock cone through any event is among the implications of our proof, thus effectively exploiting a suggestion due to F. Severi. (shrink)

Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as “automatic writing” whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant (...) reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.

This paper explores the possibilities for strategic maneuvering of the argumentative technique that Perelman and Olbrechts-Tyteca (The New Rhetoric. A Treatise on Argumentation, University of Notre Dame Press, Notre Dame/London, 1969) called dissociation. After an exploration of the general possibilities that dissociation may have for enhancing critical reasonableness and rhetorical effectiveness, the use of dissociation in the successive stages of a critical discussion is examined. For each stage, first, the dialectical moves that dissociation can be employed in are specified, then, (...) the specific ways in which dissociation contributes to fulfilling the dialectical tasks that are associated with these moves are delineated, and, finally, the rhetorical gain that␣dissociation can bring in the fulfillment of these tasks is discussed. Some general conclusions are drawn for research that aims at understanding the potential of an argumentative technique for strategic maneuvering. (shrink)

In this article, the pragma-dialectical model of a critical discussion is demonstrated to provide a useful instrument for discovering causes of an unsatisfactory development of problem-solving discussions. First a sketch is given of the development of a problem-solving discussion which, in the opinion of the participants themselves, developed in an unsatisfactory fashion. Then it is argued that this development can be traced back to flaws in the execution of the stages of a critical discussion.

Background: Discussing treatment risks has become increasingly important in medical communication. Still, despite regulations, physicians must decide how much and what kind of information to present. Objective: To investigate patients’ preference for information about a small risk of a complication of colonoscopy, and whether medical and personal factors contribute to such preference. To propose a disclosure policy related to our results. Design: Vignettes study. Setting: Department of Gastroenterology, Academic Medical Centre, the Netherlands. Patients: 810 consecutive colonoscopy patients. Intervention: A home-sent (...) questionnaire containing three vignettes. Vignettes varied in the indication for colonoscopy, complication severity and level of risk. Patients were invited to indicate their wish to be informed and the importance of such information. In addition, sociodemograhic, illness-related and psychological characteristics were assessed. Main outcome measurements: Wish to be informed and importance of information. Results: Of 810 questionnaires, 68% were returned. Patients generally wished to be informed about low-risk complications, regardless of the indication for colonoscopy or the severity of the complication. The level of risk did matter, though (OR = 2.48, SE = 0.28, p = 0.001). The information was considered less important if done for population screening purposes or diagnosis of colon cancer, if the complication was less severe (bleeding) and if the risk was smaller (0.01% and 0.1%). Patients’ information preference was also related to age, mood and coping style. Limitations: Difficulty of vignettes. Conclusions: Patients generally wish to be informed about all possible risks. However, this might become uninformative. A stepwise approach is suggested. (shrink)

Objectives: Efficient procedures for obtaining informed (proxy) consent may contribute to high influenza vaccination rates in nursing homes. Yet are such procedures justified? This study’s objective was to gain insight in informed consent policies in Dutch nursing homes; to assess how these may affect influenza vaccination rates and to answer the question whether deviating from standard informed consent procedures could be morally justified. Design: A survey among nursing home physicians. Setting & Participants: We sent a questionnaire to all (356) nursing (...) homes in the Netherlands, to be completed by one of the physicians. Results: We received 245 completed questionnaires. As 21 institutions appeared to be closed or merged into other institutions, the response was 73.1% (245/335). Of all respondents 81.9% reported a vaccination rate above 80%. Almost 50% reported a vaccination rate above 90%. Most respondents considered herd immunity to be an important consideration for institutional policy. Freedom of choice for residents was considered important by almost all. Nevertheless, 106 out of 245 respondents follow a tacit consent procedure, according to which vaccination will be administered unless the resident or her proxy refuses. These institutions show significantly higher vaccination rates (p < 0.03). Conclusions: In our discussion we focus on the question whether tacit consent procedures can be morally justifiable. Such procedures assume that vaccination is good for residents either as individuals or as a group. Even though this assumption may be true for most residents, there are good reasons for preferring express consent procedures. (shrink)

DNA double‐strand breaks (DSBs) are extremely hazardous lesions for all DNA‐bearing organisms and the mechanisms of DSB repair are highly conserved. In the eukaryotic mitotic cell cycle, DSBs are often present following DNA replication while, in meiosis, hundreds of DSBs are generated as a prelude to the reshuffling of the maternally and paternally derived genomes. In both cases, the DSBs are repaired by a process called homologous recombinational repair (HRR), which utilises an intact DNA molecule as the repair template. Mitotic (...) and meiotic HRR are managed by ‘checkpoints’ that inhibit cell division until DSB repair is complete. Here we attempt to summarise the substantial recent progress in understanding the checkpoint management of HRR in mitosis (focussing mainly on mammals) and then go on to use this information as a framework for understanding the presumed checkpoint management of HRR in mammalian meiosis.

In this article, after arguing that present approaches to improving problem-solving discussions for various reasons are not satisfactory, I turn to the pragma-dialectic approach to argumentative discourse to derive a normative framework that can serve as a point of departure to enhance the quality of problem-solving discussions. I then show how this approach can be used as analytical and evaluative instrument that can help the analyst to establish whether participants in actual practice act in a fashion that is in accord (...) with the norms posited. Two real-life problem-solving discussions provide the material for this demonstration. (shrink)

If self-interested behavior conflicts with the collective welfare, rules of cooperation are often installed to prevent egoistic behavior. We hypothesized that installing such rules may instigate personal moral norms of cooperation, but that they fail in doing so when installed by a leader who is self-interested rather than self-sacrificing. Three studies confirmed this and also showed that, consequently, only self-sacrificing leaders were able to install rules that increase cooperation without the need for a perfectly operating monitoring system.

In Computer Science stepwise refinement of algebraic specifications is a well-known formal methodology for rigorous program development. This paper illustrates how techniques from Algebraic Logic, in particular that of interpretation, understood as a multifunction that preserves and reflects logical consequence, capture a number of relevant transformations in the context of software design, reuse, and adaptation, difficult to deal with in classical approaches. Examples include data encapsulation and the decomposition of operations into atomic transactions. But if interpretations open such a new (...) research avenue in program refinement, (conceptual) tools are needed to reason about them. In this line, the paper’s main contribution is a study of the correspondence between logical interpretations and morphisms of a particular kind of coalgebras. This opens way to the use of coalgebraic constructions, such as simulation and bisimulation, in the study of interpretations between (abstract) logics. (shrink)

The vast majority of contributions to the literature on spirituality in nursing make extravagant claims about transcendence, eternity, the numinous, higher powers, higher levels of existence, invisible forces, cosmic unity, the essence of humanity, or other supernatural concepts. Typically, these assertions are made without the support of argument or evidence; and, as a consequence, alternative ways of theorizing ‘spirituality’ have been closed off, while the lack of consistent scholarship has turned the topic into a metaphysical backwater. In this paper, I (...) adopt a different premise, rejecting unsupported claims, and surveying the ‘spirituality’ terrain from a naturalistic and reductionist perspective. I argue that, if we rid ourselves of non‐naturalistic assumptions, we will discover theoretical and clinical resources in health psychology, social psychology, neuropsychology, and pharmacopsychology – resources which confirm that it is possible to conceptualize the study of existential concerns, and how health professionals might respond to them, in a properly scientific manner. In order to illustrate the potential usefulness of these resources, I will take palliative care as an example. (shrink)

GEORGE BOOLE died one hundred years ago. This essay from Cork is intended as commemorative of a great man, for too long forgotten in the College he served so well.

David Hume was a highly original thinker. Nevertheless, he was a writer of his time and place in the history of philosophy. In this book, M. A. Stewart puts Hume’s writing in context, particularly that of his native Scotland, but also that of British and European philosophy more generally. Through meticulous research Stewart brings to life the circumstances by means of which we can get a deeper understanding of Hume’s writings on the nature and reach of human reason, the foundation (...) of morals, and, especially, on the philosophy of religion. Stewart pays particular attention to Hume’s intellectual development, beginning with his education at the College of Edinburgh, the writing of his Treatise of Human Nature, and his subsequent philosophical responses to criticisms of that book. He argues that Hume’s scepticism set him at odds with the Christian Stoicism of Scottish contemporaries including that of Francis Hutcheson - and shows that this conflict played a major role in his failure to obtain the Edinburgh Moral Philosophy Chair in 1745. Stewart’s detailed study of the physical character of Hume’s surviving manuscripts in Chapters 8 and 9 provides the best available dating of his early ‘Essay on Modern Chivalry’, his ‘Early Fragment on Evil’ and the periods of composition of his Dialogues Concerning Natural Religion. Other chapters compare Hume’s theory of abstraction with that of Locke and Berkeley, provide the 17th and 18th century philosophical context of the central argument of his essay ‘Of miracles’, and consider the 18th and 19th century reception of his writings in England and Ireland.

"The availability of a paperback version of Boyle's philosophical writings selected by M. A. Stewart will be a real service to teachers, students, and scholars with seventeenth-century interests. The editor has shown excellent judgment in bringing together many of the most important works and printing them, for the most part, in unabridged form. The texts have been edited responsibly with emphasis on readability.... Of special interest in connection with Locke and with the reception of Descarte's Corpuscularianism, to students of the (...) Scientific Revolution and of the history of mechanical philosophy, and to those interested in the relations among science, philosophy, and religion. In fact, given the imperfections in and unavailability of the eighteenth-century editions of Boyle’s works, this collection will benefit a wide variety of seventeenth-century scholars." --Gary Hatfield, University of Pennsylvania.

For 150 years after Galileo's condemnation in 1633, there were many references to the trial, but no sustained, heated or polarized discussions. Then came the thesis that Galileo was condemned not for being a good astronomer but for being a bad theologian (using Scripture to support astronomical hypotheses); it began in 1784-1785 with an apology of the Inquisition by Mallet du Pan in the Mercure de France and the printing in Tiraboschi's Storia della letteratura italiana of an apocryphal letter attributed (...) to Galileo but forged by Onorato Gaetani. This thesis is not only untenable and false but inverts and subverts the truth; it proved to be long-lasting and widely accepted; so it may be labeled a myth. It was held by such writers as . Afterwards, it was generally abandoned, its death knell being pope John Paul II's speeches in 1979-1992. The myth seems to have acted as a catalyst insofar as its creation encouraged the proliferation of pro-clerical accounts and the articulation of pro-Galilean ones, thus making the discussion of Galileo's trial the cause celebre it is today.
