It is always possible to construct a real function f, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that f(X) and f(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence (...) of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox. (shrink)

. The uniform prior distribution is often seen as a mathematical description of noninformativeness. This paper uses the well-known Three Prisoners Paradox to examine the impossibility of maintaining noninformativeness throughout hierarchization. The Paradox has been solved by Bayesian conditioning over the choice made by the Warder when asked to name a prisoner who will be shot. We generalize the paradox to situations of N prisoners, k executions and m announcements made by the Warder. We then extend the consequences of hierarchically (...) placing uniform and symmetrical priors for the probability p of the Warder naming Prisoner B, say. We prove that breaks of indifference and neutrality caused by assignment of uniform and symmetrical priors in lieu of degenerate indifference probabilities hold in general. Speaking of unknown probabilities or of probability of a probability must be forbidden as meaningless.

An extension of the hypothetical experiment of Szilard, which involved the action of a one-molecule gas in an isolated isothermal system, is developed to illustrate how irreversibility may arise out of Brownian motion. As this development requires a consideration of nonmolecular components such as wheels and pistons, the thought-experiment is remodeled in molecular terms and appears to function as a perpetuum mobile.

A particle of molecular dimensions which can exist in two states is associated with a membrane pore through which molecules of a gas can pass. The gas molecules from two identical phases on either side of the membrane may pass only when the particle is in one particular state. If certain restrictions are imposed on the system, then the particle appears to act like a Maxwell's Demon(1) which “handles” the gas molecules during their passage through the pore.

The discussion among philosophers and experimental scientists on the pages of Problems of Philosophy [Voprosy filosofii] about the substance of and relations between the fundamental and applied sciences [1] persuades me that this remains a topical issue despite the very deep crisis that followed the breakup of the USSR in all spheres of society, including science, throughout the post-Soviet region. Most likely, it is precisely the crisis phenomena in society that impel its thinking part to answer the questions: What has (...) happened to us? Where are we now? Where do we go from here and by which paths? What is the role of science in changing the situation? And inasmuch as science and philosophy are the supreme creations of the human mind, called upon to reflect by specific means what is taking place in society, these questions have been at the center of philosophers' and scientists' attention.

The new thinking is making itself known in the posing and resolution of problems of man as an extremely important philosophical problem. The old philosophical question of the relationship between freedom and necessity in their dialectical interconnection once again occupies center stage.

An attempt to reveal the linguistic and cultural potential of education in the process of learning Russian as a means of communication, of cognition of the linguistic picture of the world and the phenomenon of culture is made in the article. The stages of development of linguocultural concept of teaching Russian language in the Republic of Bashkortostan are presented. New approaches to teaching Russian language are considered. The author shows that in the process of education, elementary literacy of students should (...) be achieved while they are dealing with communicative and socially important tasks contributing to the development and formation of students as linguistic personalities. The author concludes that the actual task of the modern school, which is a successful preparation for the unified state examination, should also be achieved not by increased training before the exam, but provided by the total system of education aimed at the formation of personality with a wide range of language capabilities: a cultural person, well-speaking, correct writing, able to understand and interpret the text, to express their thoughts and feelings in their own texts. Such training involves the ascent of a language personality from basic literacy to formed linguistic, communicative and cultural competences. Theoretical basis and methodological support of the concept are presented in the list of publications. (shrink)

The ethical pre-condition of randomised controlled trials is, at present, the presence of equipoise. This refers to an opinion of the investigator that there is uncertainty as to the merits of the treatments being compared. It is argued that since the decision to enrol is the potential subject’s, the investigator’s opinion is not ethically relevant. It is proposed instead that equipoise be patient-centred, and that a trial is in equipoise for a patient when enrolling gives them the same chance of (...) a good outcome as not enrolling. It is shown that trial enrolment is normally easily the best strategy for achieving a good outcome, and that trials currently thought to be unethical may be in patient-centred equipoise. This is so for three reasons: (1) patients in trials receive superior care, (2) trial enrolment minimises the risk of being a victim of a therapeutic disaster and (3) health professionals make mistakes, and a 50% chance of receiving the worse treatment until a trial reports is always better than any chance of receiving the worse treatment indefinitely. It is concluded that so long as the standard of professional conduct is the furtherance of patients’ objective interests randomised controlled trials are ethical. (shrink)

Sur la toile de fond de la theologie negative, tissee par la discussion des apories que soulevent les notions de l'ineffable et de l'un, Damascius, le dernier diadoque de l'Ecole d'Athenes, elaboreson systeme metaphysique, sans se departir de la rigueur de sa methode aporetique, qui est une critique radicale du langage a l'interieur des coordonnees fixees par le Parmenide de Platon et par les Oracles Chaldaiques. Damascius, dans une enquete unique par son ampleur et son originalite questionne tour a tour (...) Porphyre, Jamblique, Syrianus et Proclus sur les principes; il examine les problemes que pose, en derivation de l'un, la formation de la trinite; de l'un-tout (la limite), du tout-un (l'infini) et de l'unifie (le mixte ou l'etre). Lien a priori entre l'un-tout et le tout-un, l'unifie est le principe de constitution de tout ordre et de toute realite. Damascius etudie sa nature de mixte originaire et autoconstituant, d'etre exemplaire et de premier intelligible. Cette notion lui permet de pas au crible, pour la mieux fonder, la problematique neoplatonicienne de la manence, de la procession et de la conversion. Les divers niveaux d'unification de la pluralite intelligible l'amenent a construire une theorie generale des elements, des parties et des formes Au passage, de nombreux textes, capitaux du point de vue de l'ontologie et de la doctrine de la connaissance, font regretter qu'ils aient ete inconnus du Moyen Age et qu'ils le demeurent pour beaucoup de nos contemporains.

An interdisciplinary course was designed as an introduction to the applications of, and the socio-economic issues associated with, biotechnology. College students enrolled in the course were surveyed prior to the first formal lecture, and again upon completion of the course. Assessment was made of the impact of the educational materials on the attitudes and perceptions of the students toward the applications of biotechnology to agriculture. Data were collected for the first three semesters in which the course was offered. Answers to (...) survey questions were analyzed on a before and after basis. It was found that students were very accepting of biotechnology prior to taking the course, despite a generally low level of exposure to this type of technology. The course was effective in increasing the knowledge base of the students, but not as effective in allaying their perceptions of risks associated with biotechnology. (shrink)
