The first half of the twentieth century was marked by the simultaneous development of logic and mathematics. Logic offered the necessary means to justify the foundations of mathematics and to solve the crisis that arose in mathematics in the early twentieth century. In European science in the late nineteenth century, the ideas of symbolic logic, based on the works of J. Bull, S. Jevons and continued by C. Pierce in the United States and E. Schroeder in Germany were getting popular. (...) The works by G. Frege and B. Russell should be considered more progressive towards the development of mathematical logic. The perspective of mathematical logic in solving the crisis of mathematics in Ukraine was noticed by Professor of Mathematics of Novorossiysk University Ivan Vladislavovich Sleshynsky. Sleshynsky is a Doctor of Mathematical Sciences, Professor of Novorossiysk University. After studying at the University for two years he was a Fellow at the Department of Mathematics of Novorossiysk University, defended his master’s thesis and was sent to a scientific internship in Berlin, where he listened to the lectures by K. Weierstrass, L. Kronecker, E. Kummer, G. Bruns. Under the direction of K. Weierstrass he prepared a doctoral dissertation for defense. He returned to his native university in 1882, and at the same time he was a teacher of mathematics in the seminary, Odesa high schools, and taught mathematics at the Odesa Higher Women’s Courses. Having considerable achievements in the field of mathematics, in particular, Pringsheim’s Theorem proved by Sleshinsky on the conditions of convergence of continuous fractions, I. Sleshynsky drew attention to a new direction of logical science. The most significant work for the development of national mathematical logic is the translation by I. Sleshynsky from the French language “Algebra of Logic” by L. Couturat. Among the most famous students of I. Sleshynsky, who studied and worked at Novorossiysk University and influenced the development of mathematical logic, one should mention E. Bunitsky and S. Shatunovsky. The second period of scientific work of I. Sleshynsky is connected with Poland. In 1911 he was invited to teach mathematical disciplines at Jagiellonian University and focused on mathematical logic. I. Sleshynsky’s report “On Traditional Logic”, delivered at the meeting of the Philosophical Society in Krakow. He developed the common belief among mathematicians that logic was not necessary for mathematics. His own experience of teaching one of the most difficult topics in higher mathematics – differential calculus, pushed him to explore logic, since the requirement of perfect mathematical proof required this. In one of his further works of this period, he noted the promising development of mathematical logic and its importance for mathematics. He claimed that for the mathematics of future he needed a new logic, which he saw in the “Principles of Mathematics” by A. Whitehead and B. Russell. Works on mathematical logic by I. Sleszynski prompted many of his students in Poland to undertake in-depth studies in this field, including T. Kotarbiński, S. Jaśkowski, V. Boreyko, and S. Zaremba. Thanks to S. Zaremba, I. Sleshynsky managed to complete the long-planned concept, a two-volume work “Theory of Proof”, the basis of which were lectures of Professor. The crisis period in mathematics of the early twentieth century, marked by the search for greater clarity in the very foundations of mathematical reasoning, led to the transition from the study of mathematical objects to the study of structures. The most successful means of doing this were proposed by mathematical logic. Thanks to Professor I. Sleshynsky, who succeeded in making Novorossiysk University a center of popularization of mathematical logic in the beginning of the twentieth century the ideas of mathematical logic in scientific environment became more popular. However, historical events prevented the ideas of mathematical logic in the domestic scientific space from the further development. (shrink)

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

One main argument that has been offered in support of the Knowledge Account of Assertion is that it successfully makes sense of a variety of Moorean-paradoxical claims. David Sosa has objected to the Knowledge Account by arguing that it does not generalize satisfactorily to make sense of the oddity of iterated conjunctions of the form “p but I don’t know whether I know that p”. Recently, Martin Montminy has offered a defense of the Knowledge Account. In this paper, I show (...) that both Montminy’s and Sosa’s arguments fail. First, I argue that Montminy does not offer a good reply to Sosa; then I show that Sosa’s objection actually does not constitute a real threat to the Knowledge Account. (shrink)

Outdoor Education (OE) refers to organized experiential education that takes place in the outdoor, characterized by action-centered and thematic learning processes. Literature shows how OE may have beneficial effects on different areas of child development, including cognitive abilities, social skills and motor development. This relationship is not necessarily linear, but moderated by different variables. Until now, few studies have examined, using rigorous methods, the role of OE in children’s development and studies of preschool aged children remain lacking. The current study (...) aimed to explore teachers’ perceptions of children’s developmental trajectories over 2 school years, investigating whether teachers’ perceptions differed between two kindergartens, one characterized by a consolidated OE approach and the other one characterized by a more traditional method of education. The sample was composed of 20 teachers, evaluating 93 children aged 3-5 (M= 46.95 months, SD= 6.73; 42 males): 13 teachers were from a traditional kindergarten (Traditional Group- TG) and evaluated 52 children; 7 teachers were from an OE kindergarten (Outdoor Group – OE) and observed 41 children. All the teachers completed the Kuno Beller Developmental Tables (Beller, 1995), in order to describe specific child developmental areas in 4 consecutive moments during 2 school years (T1-T2: January-May 2014; T3-T4: October 2014-May 2015). The 20 teachers also completed the “Outdoor Activities/Trips Diary”, an instrument created for this study to collect qualitative data on the characteristics of outdoor activities. Results showed that, in all the developmental areas, OE teachers perceived higher scores over time were found for the Outdoor Group compared to the Traditional one. Specifically, GLM ANOVAs Repeated Measures revealed a significant interaction of the 2 variables Time and Groups (p<0.001): contrast analyses showed that OE children, compared to the TG children, were perceived by their teachers with higher levels in all developmental areas at T1 and T2, but not at T3 and T4. The findings suggest that the OE activites, compared to indoor ones and according to teachers' perceptions, offer greater opportunities to promote the child’s development at different levels. especially when children are younger. Future studies are recommended analyzing possible moderating variables and long term effects of OE. (shrink)

This text has already been published in Studies in Philosophy and Education, Feb. 2018, n° 37, p.103–107. As we all know it, writing and reading takes time. In the contemporary social and academic context, often shaped by a destabilizing sense of acceleration and urgency, protecting the moments required for such ‘time-consuming' activities is not something that can be taken for granted anymore. The way we commit to a specific task expresses as much about the meaning it may carry that what (...) we - Débats. (shrink)

This work considers the future of driving in terms of both its short- and long-term horizons. It conjectures that human-controlled driving will follow in the footsteps of a wide swath of other, now either residual or abandoned human occupations. Pursuits that have preceded it into oblivion. In this way, driving will dwindle down into only a few niche locales wherein enthusiasts will still persist, much in the way that steam train hobbyists now continue their own aspirational inclinations. Of course, the (...) value of any such prognostication is in direct proportion to the degree that information is conveyed, and prospective uncertainty reduced. In more colloquial terms: the devil is in the details of these coming transitions. It is anticipated that we will see a progressive transformation of the composition of on-road traffic that will be registered most immediately in the realm of professional transportation in which the imperative for optimization exceeds that in virtually all other user segments. The transition from manual control to full automation will be more punctate than gradualist in is evolutionary development. As performance optimization slowly exhausts the commercial sector, it will progressively transition more into the discretionary realm by dint of simple technology transfer alone. The hedonic dimension of everyday driving will be dispersed and pursued by progressively fewer individuals. The traveling window of generational expectation will soon mean that human driving will be largely ‘forgotten,’ as each sequential generation matures without this, still presently common, experience. Indications of this stage of progress are beginning to... (shrink)

We look at various notions of a class of definability operations that generalise inductive operations, and are characterised as “revision operations”. More particularly we: (i) characterise the revision theoretically definable subsets of a countable acceptable structure; (ii) show that the categorical truth set of Belnap and Gupta’s theory of truth over arithmetic using \emph{fully varied revision} sequences yields a complete \Pi13 set of integers; (iii) the set of \emph{stably categorical} sentences using their revision operator ψ is similarly \Pi13 and which (...) is complete in Gödel’s universe of constructible sets L; (iv) give an alternative account of a theory of truth—realistic variance that simplifies full variance, whilst at the same time arriving at Kripkean fixed points.

Objective: The objectives of this study are to understand the current functions, structure and operation of hospital ethics committees (HECs) in Shanghai and to facilitate their improvement. Methods: (1) A questionnaire survey, (2) interviews with secretaries and (3) on-site document reviews of HECs in Shanghai were used in the study, which surveyed 33 hospitals. Results: In Shanghai, 57.56% of the surveyed hospitals established HECs from 1998 to 2005. Most HECs used bioethical review of research involving human subjects as well as (...) bioethical review or consultation regarding medical care services and administrative decision- making. Of the surveyed HECs, 14.3% did not provide any formal bioethical training to the HECs’ members and many HECs had no standard operating procedures. Some HECs had no clear definition of what was “conflict of interest” that should be considered by the HECs, while 44.4% of the HECs did not perform continuing review. Discussion: After the issues of related national regulations, more and more hospitals established HECs in Shanghai, but the functions of HECs need to be further developed and formal training on bioethics should be provided to HEC members. To assure the independence and good performance of HECs, the conflict of interest procedure, the standard operating procedures and bioethical review should be improved. Conclusion: HECs in Shanghai had developed in the preceding 10 years and they played great roles in protecting the rights and welfare of human subjects and patients; some areas need improvement.

This paper situates the moral domain of practice within the context of a particular description of nursing practice – one that sees human interaction at the heart of that practice. Such a description fits not only with professional rhetoric but also with literature from patients and recent empirical work exploring the nature of nursing practice.Martha Levine in her 1977 description of ethics, within the context of nursing practice, indicated that what was important from an ethical perspective was how we interact (...) with each other, with patients and colleagues, on a daily basis. What enables such interaction to display moral sensitivity, insight into patient need, and a focus on the good for the patient? Of relevance when answering this question is the empirical evidence indicating that professional socialization, as a nurse or a doctor, may dull the individual’s moral sense. If this is the case, cognizance needs to be taken of such evidence when identifying theoretical approaches from mainstream ethics that may provide insight and value for nurse education. It is suggested that such insight and value can be gained from a consideration of the work of Aristotle, Murdoch, and Vetlesen. (shrink)

The role of emotions in ethics is often taken by philosophers and others as antithetical to rationality. On the most basic level (in undergraduate philosophy exams and elsewhere), stating an opinion in the form "I feel that p" can be a way of sidestepping the demand for reasons. But emotions can sometimes also be seen as supplying reasons for moral judgment to the extent that they involve evaluations--and a way of communicating them across different moral perspectives.

SummaryThe Gricean maxims of conversation are regulated by a supermaxim which determines what is relevant or not for a particular conversation. This maxim, involving a pragmatical knowledge, imposes specific restrictions on conversational strategy. It is called the “maxim of conversation topology” because it fixes the topos of a conversation.RésuméDans cet article nous démontrons que les maximes de la conversation, établies par H.P. Grice, sont dominées par une supermaxime qui détermine ce qui est pertinent et ce qui n'est pas pertinent pour (...) une certaine conversation. Cette maxime, qui implique une connaissance ?on;ordre pragmatique, impose des restrictions spécifiques sur la stratégie de conversation. Cette supermaxime, axiomatiquement premiére, est appelée ici la maxime de la topologie de la conversation, puisque c'est elle qui fixe le topos?on;une conversation.ZusammenfassungDie Maximen, die Grice für die Durchführung einer Konversation aufstellt, werden ihrerseits durch eine Obermaxime geregelt, die bestimmt, was für eine gegebene Konversation relevant ist oder nicht.

Sie wird die Maxime der Konversationstopologie genannt, weil sie den Topos einer Konversation festlegt. (shrink)

The figure of Peter the Tomb, various aspects of his life and activity, as well as the era called by his name, have long been the subject of study by numerous scholars, comprehensive and meticulous research. It is enough to mention the works of M.Grushevsky, A.Zhukovsky, V.Klimov, A.Kolodny, V.Nichik, O.Sarapin, L.Filipovich and V.Shevchenko, in which the phenomenon of the metropolitan, his spiritual and religious dominant, is thoroughly and thoroughly explained, the influence of P. Mogila's heritage on the past and present. (...) And yet it is impossible to talk about the exhaustiveness of this topic, because such inexhaustibility is dictated by the very universe of its multidimensional activity. This is what determines the relevance of the proposed article. And this, in turn, gives rise to reflections on the need for scientific innovative understanding of religious philosophy as a constant basis of thinking of Petro Mohyla, which, in particular, was reflected in his "Notebook", which is still a little-studied phenomenon of Ukrainian spiritual culture, for the first time it saw the world only in 1995, more than 60 years after its invention by M. Grushevsky. This work, like all narratives on the spiritual and religious themes that make up it, is an integral part of the metropolitan's religious and philosophical heritage. (shrink)

It has been argued that the fundamental laws of physics are deceitful in that they give the impression of greater unity and coherence in our theories than is actually found to be the case. Causal stories and phenomenological relationships are claimed to provide a more acceptable account of the world, and only theoretical entities — not laws — are considered as perhaps corresponding to real features of the world.This paper examines these claims in the light of the author's own field (...) of research: high energy physics. Some of the distinctions upon which the above conclusions are based are found not to be tenable in practice. Examples from experimental particle physics are presented which suggest an important role of the underlying theoretical structure which cannot be overlooked. It is argued that the fundamental theories must, in fact, be treated as being as worthy or unworthy of ontological commitment as the entities they postulate or the phenomenological relationships they inspire. Whilst it is conceded that aspects of the current theoretical formalism belie literal interpretation, it is maintained that revision in these particular areas need not affect the symmetry principles, particle spectra, or coupling strengths that largely determine the empirical content of the theory.

Bioethics has become a field of new challenges for Ibero-America and the Caribbean. A seeming uniformity in the region hides a rich heterogeneous society. A brief survey of bioethical developments in different Ibero- American countries is provided as well as the bioethical problems and approaches peculiar to the region. Some of the unique features of bioethics in this region, it is suggested, could infuse new life into the U.S. and European bioethics discussion. Finally, a bibliography of Ibero-American bioethics literature is (...) provided for North American and European readers. (shrink)

Psychoanalysis had a profound influence on formation of Merleau-Ponty’s thought. However, at the same time, he rejects Freud’s idea that the unconscious consists of latent mental contents that cause a certain type of behavior. Instead of a hidden experience, Merleau-Ponty argues that the unconscious is an ambiguous consciousness. In The Structure of Behavior and The Phenomenology of Perception, he specifies this ambiguity by means of the concepts of habit, bad faith, bodily expression, affective intentionality and body schema. In this paper, (...) I will present the interconnection of these aspects of the human existence, following Merleau-Ponty’s two early major works. Further, I will show the difference of Merleau-Ponty’s notion of bad faith from that of Sartre, and, finally, I will suggest a limitation of Merleau-Ponty’s approach to the unconscious. (shrink)

Three experiments explore the role of working memory in motor skill acquisition and performance. Traditional theories postulate that skill acquisition proceeds through stages of knowing, which are initially declarative but later procedural. The reported experiments challenge that view and support an independent, parallel processing model, which predicts that procedural and declarative knowledge can be acquired separately and that the former does not depend on the availability of working memory, whereas, the latter does. The behaviour of these two processes was manipulated (...) by providing or withholding visual (and auditory) appraisal of outcome feedback. Withholding feedback was predicted to inhibit the use of working memory to appraise success and, thus, prevent the formation of declarative knowledge without affecting the accumulation of procedural knowledge. While the first experiment failed to support these predictions, the second and third experiments demonstrated that procedural and declarative knowledge can be acquired independently. It is suggested that the availability of working memory is crucial to motor performance only when the learner has come to rely on its use. (shrink)

The present work investigates whether the hemispheric processing of both verbal and emotional stimuli, studied by means of a dichotic listening task, differs between normal high and low dissociators as assessed by the Dissociative Experiences Scale . Development, reliability and validity of a dissociation scale. Journal of Nervous and Mental Disease, 174, 727–735). Two groups of subjects , participated in the experiment. The task consisted in identifying both verbal and emotional stimulus-targets, respectively, on successive sessions. Reaction time and response accuracy (...) were registered and analysed using ANOVA . The interaction between stimuli , channel , and dissociation level reached statistical significance in terms of accuracy measures = 4.75; p < .05). Both high and low dissociators exhibited the expected right ear advantage on verbal targets. On the other hand, whereas low dissociators exhibited the expected left ear advantage on emotional targets, high dissociators failed to follow this typical pattern of hemispheric asymmetry: both hemispheres exhibited similar performances. These results confirm the hypothesis that dissociation is related to changes in hemispheric processing, specifically of emotional information. (shrink)
