S. Ulam asked about the number of nonisomorphic projective algebras with k generators. This paper answers his question for projective algebras of finite dimension at least three and shows that there are the maximum possible number, continuum many, of nonisomorphic one-generated structures of finite dimension n, where n is at least three, of the following kinds: projective set algebras, projective algebras, diagonal-free cylindric set algebras, diagonal-free cylindric algebras, cylindric set algebras, and cylindric algebras. The results of this paper extend earlier (...) results to the collection of cylindric set algebras and provide a uniform proof for all the results. Extensions of these results for dimension two are discussed where some modifications on the hypotheses are needed. Furthermore for α |geq 2, the number of isomorphism classes of regular locally finite cylindric set algebras of dimension α of the following two kinds are computed: ones of power κ for infinite $\kappa \geq|\alpha|$ , and ones with a single generator.

Countable homogeneous relational structures have been studied by many people. One area of focus is the Ramsey theory of such structures. After a review of background material, a partition theorem of Laflamme, Sauer, and Vuksanovic for countable homogeneous binary relational structures is discussed with a focus on the size of the set of unavoidable colors.

Suppose that α = γ + δ where $\gamma \geq \delta > 0$ . Then there is a graph G = (ω ω α ,E) which has no independent set of order type ω ω α and has no pentagram (a pentagram is a set of five points with all pairs joined by edges). In the notation of Erdos and Rado, who generalized Ramsey's Theorem to this setting, $\omega^{\omega^\alpha} \nrightarrow (\omega^{\omega^\alpha},5)^2.$.

The goal of this short note is to interest set theorists in the order type ω*ω1, and to encourage them to work on the question of whether or not the Continuum Hypothesis decides the partition relation τ→2, for τ=ω*ω1 and for τ=ω1ω+2.

Understanding how people comprehend visual narratives (including picture stories, comics, and film) requires the combination of traditionally separate theories that span the initial sensory and perceptual processing of complex visual scenes, the perception of events over time, and comprehension of narratives. Existing piecemeal approaches fail to capture the interplay between these levels of processing. Here, we propose the Scene Perception & Event Comprehension Theory (SPECT), as applied to visual narratives, which distinguishes between front-end and back-end cognitive processes. Front-end processes occur (...) during single eye fixations and are comprised of attentional selection and information extraction. Back-end processes occur across multiple fixations and support the construction of event models, which reflect understanding of what is happening now in a narrative (stored in working memory) and over the course of the entire narrative (stored in long-term episodic memory). We describe relationships between front- and back-end processes, and medium-specific differences that likely produce variation in front-end and back-end processes across media (e.g., picture stories vs. film). We describe several novel research questions derived from SPECT that we have explored. By addressing these questions, we provide greater insight into how attention, information extraction, and event model processes are dynamically coordinated to perceive and understand complex naturalistic visual events in narratives and the real world.

In this interview, Jean-Luc Marion recalls the intellectual world of Paris in 1970s, reflecting on how his engagement with the ubiquitous “death of God” question led to the sketches of God without Being first presented at this 1979 Colloquium, and discusses the criticism it provoked not only from Heideggerians but also from Thomists. He discusses the reception history of phenomenology in France the reasons for the particular power it gained among thinkers of his generation. Finally, he recounts how his (...) work has led from the 1979 Colloquium through the “Theological Turn” and up to his forthcoming D’ ailleurs, la révélation, which he briefly previews here. Marion closes with words on originality, criticism, and the particular challenges of the contemporary world that await philosophical thinking today. (shrink)

La raison pour laquelle il y a inadéquation de notre connaissance à la nature des corps extérieurs, mais aussi à celle de notre corps propre ainsi qu'à celle notre esprit, et donc à la nature de notre ego, c'est que nous sommes des êtres finis. Pour Descartes comme pour Spinoza la finitude de notre entendement rend impossible l'adéquation de la connaissance. À la connaissance adéquate, Descartes substitue la connaissance complète : certaine, mais non-absolue, vérifiée, mais seulement provisoire. La mise au (...) jour de cette première origine cartésienne de la théorie spinoziste de l'idée adéquate conduit l'auteur à l'hypothèse suivante : cette théorie accomplirait au sein de la métaphysique rationnelle développée dans l'Éthique la doctrine de la révélation et de la grâce présente dans la pensée théologique chrétienne. Dès lors il met en évidence la correspondance entre la vision béatifique suarézienne et la connaissance adéquate spinozienne, la première anticipant historiquement la seconde, à cette différence près que pour Thomas d'Aquin comme pour Suarez, « c'est la vision béatifique qui commande la connaissance », alors que c'est l'inverse pour Spinoza. Pour l'auteur, c'est le refus de toute création qui a conduit Spinoza à retrouver le modèle théologique de la vision béatifique comme moyen d'accès à la connaissance adéquates des choses et de Dieu.

Inversion Quelle fonction pouvons-nous reconnaitre à la philosophie de la religion? Devons-nous même lui en reconnaître encore une? On pourrait en douter, ne serait-ce qu’en considérant son origine, en fait moderne. À proprement parler, il ne saurait y avoir de philosophie de la religion, car elle ne peut intervenir sans la constitution, ou plutôt la reconstitution d’un concept de « religion ». Or ce concept a une origine moderne, rendue possible par l’éclatement de la catholicité occidenta...

This study described and analysed the circumstances surrounding a fatal car accident involving personnel of a multinational corporation in a developing country. For some companies, road accidents are the leading cause of work-related fatalities in developing countries. This reality highlights the ethical dilemmas encountered in a global workplace. Questions as to how a company addresses safety concerns outside the standard work environment, the ethics of operating in a risky environment and the requirements for international consistency in compensation standards for loss (...) of life were addressed. The authors argued that multinational companies should localize health and safety practices to address the important asymmetries between different regions of the world regarding social, cultural and infrastructural issues. Furthermore, the authors analysed the leadership role that should be played by multinational companies to help and support national governments to reduce traffic fatalities in developing countries. From this perspective, the article represents a contribution for the body of knowledge dealing with the business–society relations. The authors used an action research approach to address these issues, both in response to the particular incident and to contribute to the body of research in this field. (shrink)

Overdose deaths involving prescription opioids killed more than 17,000 Americans in 2017, marking a five-fold increase since 1999. High prescribing rates of opioid analgesics have been a substantial contributor to prescription opioid misuse, dependence, overdose and heroin use. There was recognition approximately ten years ago that opioid prescribing patterns were contributing to this startling increase in negative opioid-related outcomes, and federal actions, including Medicare reimbursement reform and regulatory actions, were initiated to restrict opioid prescribing. The current manuscript is a description (...) of those actions, the effect of those actions on opioid prescribing and related patient outcomes. We also describe our proposal of methods of expanding these efforts as an important piece to further reduce opioid-related misuse, dependence, and overdose death. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Preface: Virtual Entities in ScienceRobert Harlander, Jean-Philippe Martinez, Friedrich Steinle, and Adrian WüthrichIt is not only since the sudden increase of online communication due to the COVID-19 situation that the concept of the “virtual” has made its way into everyday language. In this context, it mostly denotes a digital substitute for a real object or process. Virtual reality is perhaps the best-known term in this respect. With these (...) digital connotations, “virtuality” has also been used in science and research: Chemists use virtual laboratories, biologists do virtual scanning of molecular structures, and geologists engage in virtual field trips. But the concept of the virtual has a much longer tradition, dating back to long before the dawn of the digital age. Virtual images and virtual displacements were introduced in classical physics already in the late seventeenth and eighteenth centuries, respectively. They represent auxiliary objects or processes without instantiation, with the purpose of efficiently describing specific physical systems. In today’s physics, the term “virtual” is mostly associated with the quantum world, first and foremost with the “virtual particle” of quantum field theory. It has become such an integral part of modern high energy physics that its ontological character may be considered to go beyond the purely auxiliary, which is typically associated with the virtual. [End Page 263]In other disciplines, however, use of the term virtual without a digital connotation is much rarer. While concepts like “virtual adrenaline” show up in physiological research around 1940s, and Charles Darwin, in a private note in January 1840,1 spoke of “virtual change” in the context of embryology, these examples seem to be singular occurrences of entities that were explicitly called “virtual.” The basic idea behind the terminology of the virtual, however, might be much more common, even outside of physics. The “invisible hand” in economics, or the “vital force” in biology, for instance, may carry aspects of a virtual entity, even if they have not been referred to that way.These different observations raise several questions about the status of virtual entities in science. What has led scientists to call one entity “virtual” and not another? Do all virtual entities in science have the same roots and meet the same characteristics? Are they more than auxiliary objects or processes? Why does physics seem to occupy a specific position with respect to the use of the notion of virtuality? These are some points that led us to discuss virtual entities in science during a workshop, out of which grew the present collection. We invited contributions that addressed the historical formation and philosophical interpretation of concepts of virtual entities in physics and other disciplines—in whatever terms they may come. The main goal of the workshop was to bring to the fore similarities and differences in the meanings and functions of these concepts, so as to be able to precisely characterize why certain entities are considered virtual in specific contexts, why a different terminology was often used in each individual case, and in what sense the virtual entities relate to the real world.The organization of the workshop was part of our project “The formation and development of the concept of virtual particles,” a subproject of the Research Unit “The Epistemology of the Large Hadron Collider,” funded by the Deutsche Forschungsgemeinschaft (DFG) and Der Wissenschaftsfonds (FWF). The workshop took place online on four consecutive Fridays in March 2021. It brought together contributors who discussed the role of the concept of the virtual in theoretical as well as experimental activities, and investigated into the origins of the terminology of the virtual as it was applied to the various disciplines of natural science. Dealing with historical, philosophical, but also methodological questions, the presentations covered a wide time range, from the Middle Ages to the present day. While physics naturally emerged as the dominant field, natural philosophy, computer science and biology were also addressed. The papers in this volume were contributed by participants in this workshop and approach the subject from different angles. [End Page 264]First, Friedrich Steinle provides us with an introductory piece that reflects on the specific meaning of the use of the term ‘virtual’ in science. He highlights and... (shrink)

Our language and metaphors about environmental issues reflect and affect how we perceive and manage them. Discourse on invasive species is dominated by aggressive language of aliens and invasion, which contributes to the use of war-like metaphors to promote combative control. This language has been criticised for undermining scientific objectivity, misleading discourse, and restricting how invasive species are perceived and managed. Calls have been made for alternative metaphors that open up new management possibilities and reconnect with a deeper conservation ethic. (...) Here, we turn to Indigenous perspectives because they are increasingly recognised as offering important and novel voices in invasive species discourse. We examine how Australian Aboriginal elders and land managers (rangers) speak about 'environmental weeds' (the term used to describe invasive plants in Australia) and weed management. Based on qualitative research with five Aboriginal groups in the Kimberley region of Western Australia, our findings indicate that Aboriginal elders speak about weeds through passive, neutral language and prefer metaphors for weed management that focus on health, care and creation. We outline the influence that this language has for how rangers practice weed work and discuss its implications for the mainstream paradigm. (shrink)

Culture, livelihoods and political-economic status all influence people's perception of introduced and invasive species, shaping perspectives on what sort of management of them, if any, is warranted. Indigenous voices and values are under-represented in scholarly discourse about introduced and invasive species. This paper examines the relationship between the Xeni Gwet'in First Nation (one of six Tsilhqot'in communities) and wild or free-roaming horses in British Columbia, Canada. We outline how Xeni Gwet'in people value horses and experience management actions, contextualising the controversy (...) over wild horses amidst power imbalances in the expression of environmental values. We suggest that Indigenous voices are vital to include when evaluating impacts of controversial species and developing management strategies. (shrink)

Si l'on reconnaît que la métaphore n'est pas un simple ornement du langage et que l'histoire de la pensée philosophique et scientifique s'est nouée autour de certaines "métaphores directrices" et de leurs changements de sens, il faut réviser notre image habituelle des rapports entre rhétorique et pensée conceptuelle, parcourir à nouveaux frais k cours de notre tradition et envisager autrement la succession des grandes métaphysiques. À cet égard, la pensée de Hans Blumenberg offre des instruments essentiels. Anselm Haverkamp et (...) class='Hi'>Jean-Claude Monod se sont attachés tout à la fois à éditer, situer et commenter les travaux de Blumenberg, tout en leur donnant des prolongements personnels. Ces prolongements et développements ne concernent pas seulement la réflexion sur la "métaphore absolue", telle que la "métaphorologie" de Blumenberg l'a illustrée, mais aussi l'histoire de la rhétorique et de la poétique, les moyens d'expression de la philosophie, les limites de la phénoménologie et les impasses de "l'histoire de l'être" heideggérienne, la portée anthropologique du mythe, les transformations de la mimèsis. Sont ici rassemblées des contributions de deux philosophes qui, l'un et l'autre, ont "pensé avec" Blumenberg."--Page 4 of cover. (shrink)

Résumé Pour parler vulgairement l’alcoolique a un problème avec le monde et avec l’altérité en raison de sa double figure : il est familier et étrange, toujours ailleurs. Autrement dit, c’est son problème d’identité ou le fait de « rester soi-même » (ipséité) qui est ici questionné car on ne doute pas qu’il est mais on ne sait plus ce qu’il est lorsqu’il boit. Le problème du soi chez l’alcoolique est un problème central lorsque nous envisageons le boire ou l’alcoolisme. (...) Il sera abordé ici dans sa dimension anthropologique, philosophique et clinique. Nous verrons en chemin que nous serons confrontés à une forme de limite qui interroge la place du soignant et la notion de thérapeute. C’est de notre place de soignant que nous parlons. (shrink)

Preadolescence is an important period for the consolidation of certain arithmetic facts, and the development of problem-solving strategies. Obese subjects seem to have poorer academic performance in math than their normal-weight peers, suggesting a negative effect of obesity on math skills in critical developmental periods. To test this hypothesis, event-related potentials were collected during a delayed-verification math task using simple addition and subtraction problems in obese [above 95th body mass index percentile] and non-obese preteens with different levels of math skill; (...) thirty-one with low math skills and thirty-one with high math skills. No significant differences between weight groups were observed in task accuracy regardless of their mathematical skill level. For ERPs, electrophysiological differences were found only in the subtraction condition; participants with obesity showed an electrophysiologic pattern associated with a reduced ability to allocate attention resources regardless of their math skill level, these differences were characterized by longer P300 latency than their normal-weight peers. Moreover, the participants with obesity with high math skills displayed hypoactivity in left superior parietal lobule compared with their normal-weight peers. Additionally, obese preteens with low math skills displayed smaller arithmetic N400 amplitude than non-obese participants, reflecting difficulties in retrieving visual, semantic, and lexical information about numbers. We conclude that participants with obesity are less able than their normal-weight peers to deploy their attention regardless of their behavioral performance, which seems to have a greater effect on obese participants with low math skills because they also show problems in the retrieval of solutions from working memory, resulting in a delay in the development of mathematical skills.

En 2007, le philosophe danois Frederik Stjernfelt a donné une nouvelle vigueur aux études sur les diagrammes en publiant son opus majeur Diagrammatology. Ce terme a acquis l’extension d’une sous-discipline à part entière à l’intérieur des études sémiotiques. La diagrammatologie fédère aujourd’hui des recherches venues des sciences cognitives aussi bien que du post-structuralisme, des mathématiques et des études littéraires. Frederik Stjernfelt explique comment la diagrammatologie résulte pour lui d’une redéfinition de certains concepts fondamentaux (ceux de signe, de proposition et de (...) diagramme au premier chef) amorcée par le père du pragmatisme, Charles S. Peirce. (shrink)
