Within the last decade, several approaches using quaternion numbers to handle and model multiband images in a holistic manner were introduced. The quaternion Fourier transform can be efficiently used to model texture in multidimensional data such as color images. For practical application, multispectral satellite data appear as a primary source for measuring past trends and monitoring changes in forest carbon stocks. In this work, we propose a texture-color descriptor based on the quaternion Fourier transform to extract relevant information from multiband (...) satellite images. We propose a new multiband image texture model extraction, called FOTO++, in order to address biomass estimation issues. The first stage consists in removing noise from the multispectral data while preserving the edges of canopies. Afterward, color texture descriptors are extracted thanks to a discrete form of the quaternion Fourier transform, and finally the support vector regression method is used to deduce biomass estimation from texture indices. Our texture features are modeled using a vector composed with the radial spectrum coming from the amplitude of the quaternion Fourier transform. We conduct several experiments in order to study the sensitivity of our model to acquisition parameters. We also assess its performance both on synthetic images and on real multispectral images of Cameroonian forest. The results show that our model is more robust to acquisition parameters than the classical Fourier Texture Ordination model. Our scheme is also more accurate for aboveground biomass estimation. We stress that a similar methodology could be implemented using quaternion wavelets. These results highlight the potential of the quaternion-based approach to study multispectral satellite images.

Intelligibility and interpretability related to artificial intelligence (AI) are crucial for enabling explicability, which is vital for establishing constructive communication and agreement among various stakeholders, including users and designers of AI. It is essential to overcome the challenges of sharing an understanding of the details of the various structures of diverse AI systems, to facilitate effective communication and collaboration. In this paper, we propose four fundamental terms: “I/O,” “Constraints,” “Objectives,” and “Architecture.” These terms help mitigate the challenges associated with intelligibility (...) and interpretability in AI by providing appropriate levels of abstraction to describe structure of AI systems generally, thereby facilitating the sharing of understanding among various stakeholders. The relationship between the Objective of AI designers and the Purpose of AI users is linked to the issues of AI alignment. (shrink)

Various four- and three-valued modal propositional logics are studied. The basic systems are modal extensions BK and BS4 of Belnap and Dunn's four-valued logic of firstdegree entailment. Three-valued extensions of BK and BS4 are considered as well. These logics are introduced semantically by means of relational models with two distinct evaluation relations, one for verification and the other for falsification. Axiom systems are defined and shown to be sound and complete with respect to the relational semantics and with respect to (...) twist structures over modal algebras. Sound and complete tableau calculi are presented as well. Moreover, a number of constructive non-modal logics with strong negation are faithfully embedded into BS4, into its three-valued extension B3S4, or into temporal BS4, BtS4. These logics include David Nelson's three-valued logic N3, the four-valued logic N4 bottom, the connexive logic C, and several extensions of bi-intuitionistic logic by strong negation. (shrink)

Qui étaient les gnostiques? Simplement des hérétiques? Ou bien ont-ils, par leurs questionnements, contribué à la redéfinition de la religion monothéiste? Relevaient-ils du judaïsme, du christianisme, du mandéisme, du sabéisme, du manichéisme? Comment le mouvement gnostique a-t-il influencé le développement du christianisme dans l’Antiquité? L’Église a-t-elle rejeté ce mouvement? L’ouvrage de Serge Hutin répond à ces questions essentielles.

L’accueil familial de la protection de l’enfant traverse une crise importante. Comprendre cette crise passe par l’analyse critique du dispositif d’Aide sociale à l’enfance dans lequel s’inscrit l’accueil familial. Les évolutions du métier d’assistant familial ont déstabilisé le dispositif lorsqu’elles n’ont pas été accompagnées par des transformations des organisations et des pratiques. La loi de 2016 qui réoriente la protection de l’enfance sur les besoins de l’enfant est une opportunité pour l’accueil familial. À partir de l’analyse critique des pratiques en (...) protection de l’enfance, cet article propose les concepts de pourvoyance des besoins de l’enfant, de parentalité empêchée et de développement du pouvoir être parent pour penser les pratiques de l’accueil familial d’enfant.

It is sometimes suggested that Collingwood’s philosophy of history is decidedly anti-naturalist and argues for a complete separation between history and the natural sciences. The purpose of this paper is to examine this suggestion and to argue that Collingwood’s conception of the relationship between history and natural sciences is much more subtle and nuanced than such a view would allow for. In fact, there is little in Collingwood to offend contemporary naturalistic sensibilities reasonably construed. The impression that Collingwood’s views are (...) incompatible with naturalism stems, in part, from an overly Kantian interpretation of the idea of rationality, as applied to historical agents, in terms of transcendentally fixed norms. This difficulty, however, does not arise if we opt for a more Hegelian interpretation of rationality in terms of continuity in thought, which Collingwood himself seemed to favor. Examining Collingwood’s pronouncements on these topics leads one to the conclusion that, while objecting to the excesses of early naturalism, Collingwood saw no insurmountable obstacles to the reconciliation of science and history and their potential collaboration in some areas.

While philosophers have, for centuries, pondered upon the relation between mind and brain, neuroscientists have only recently been able to explore the connection analytically — to peer inside the black box. This ability stems from recent advances in technology and emerging neuroimaging modalities. It is now possible not only to produce remarkably detailed images of the brain’s structure (i.e. anatomical imaging) but also to capture images of the physiology associated with mental processes (i.e. functional imaging). We are able to see (...) how specific regions of the brain ‘light up’ when activities such as reading this book are performed, and how our neurons and their elaborate cast of supporting cells organize and coordinate their tasks. As demonstrated in the other chapters of this book, the mapping of the human mind (mostly by measuring regional changes in blood flow, initially by positron emission tomography (PET) and recently by functional magnetic resonance imaging or (fMRI)) has provided insight into the functional neuroanatomy of neuropsychiatric diseases. Amazingly, the idea that regional cerebral blood flow (rCBF) is related intimately to brain function goes back more than a century. As is often the case in science, this idea was initially the result of unexpected observations. The Italian physiologist Angelo Mosso first expressed the idea while studying pulsations of the living human brain that keep pace with the heartbeat (Mosso, 1881). These brain pulsations can be observed on the surface of the fontanelles in newborn children. Mosso believed that they reflected blood flow to the brain. He observed similar pulsations in an adult with a post-traumatic skull defect over the frontal lobes. While studying this subject, a peasant named Bertino, Mosso observed a sudden increase in the magnitude of the ‘brain’s heart-beats’ when the church bells signalled 12 o’clock, the time for a required prayer. The changes in brain pulsations occurred independently of any change in pulsations in the forearm.. (shrink)

In the monograph [1] of Chang and Keisler, a considerable extent of model theory of the first order continuous logic is ingeniously developed without using any notion of provability.In this paper we shall define the notion of provability in continuous logic as well as the notion of matrix, which is a natural extension of one in finite-valued logic in [2], and develop the syntax and semantics of it mostly along the line in the preceding paper [2]. Fundamental theorems of model (...) theory in continuous logic, which have been proved with purely model-theoretic proofs in [1], will be proved with proofs which are natural extensions of those in two-valued logic.

While attention to research integrity has been growing over the past decades, the processes of signalling and denouncing cases of research misconduct remain largely unstudied. In this article, we develop a theoretically and empirically informed understanding of the causes and consequences of reporting research misconduct in terms of power relations. We study the reporting process based on a multinational survey at eight European universities. Using qualitative data that witnesses of research misconduct or of questionable research practices provided, we aim to (...) examine actors’ rationales for reporting and not reporting misconduct, how they report it and the perceived consequences of reporting. In particular we study how research seniority, the temporality of work appointments, and gender could impact the likelihood of cases being reported and of reporting leading to constructive organisational changes. Our findings suggest that these aspects of power relations play a role in the reporting of research misconduct. Our analysis contributes to a better understanding of research misconduct in an academic context. Specifically, we elucidate the processes that affect researchers’ ability and willingness to report research misconduct, and the likelihood of universities taking action. Based on our findings, we outline specific propositions that future research can test as well as provide recommendations for policy improvement. (shrink)

En partant de l’observation de patients ayant subi une transplantation hépatique, nous constatons que la réhabilitation est souvent très laborieuse. Le malade se trouve transformé par l’intervention des autres sur lui-même. Pour se réapproprier ce corps, il est nécessaire de redonner un sens propre à ce qui s’est passé, loin des explications techniques qui ont permis aux soignants d’agir. Ces explications ne lui permettent pas de comprendre. La dialectique du comprendre et de l’expliquer est difficile à saisir pour le soignant (...) qui privilégie les explications, alors qu’à cette phase du soin elles sont étranges pour le malade. Pour comprendre il lui est plus simple de recréer sa propre tragédie, avec ses propres rôles, un début et une fin. Ses particularités, son ipséité réapparaissent et il peut dresser le bilan de ce qu’il a subi. Il s’agit de sa première action, un « agir narratif ». S’acceptant tel qu’il est devenu, il peut dès lors se considérer comme un nouvel individu, un être guéri non par décret médical, mais par sa propre action. Pour que ce récit soit accueilli, il est nécessaire que le soignant lui face hospitalité et acte de reconnaissance. C’est l’enjeu éthique de cette réflexion : le soignant qui permet, par l’écoute, une autre écriture. (shrink)

The recent trend in cognitive robotics experiments on language learning, symbol grounding, and related issues necessarily entails a reduction of sensorimotor aspects from those provided by a human body to those that can be realized in machines, limiting robotic models of symbol grounding in this respect. Here, we argue that there is a need for modeling work in this domain to explicitly take into account the richer human embodiment even for concrete concepts that prima facie relate merely to simple actions, (...) and illustrate this using distributional methods from computational linguistics which allow us to investigate grounding of concepts based on their actual usage. We also argue that these techniques have applications in theories and models of grounding, particularly in machine implementations thereof. Similarly, considering the grounding of concepts in human terms may be of benefit to future work in computational linguistics, in particular in going beyond “grounding” concepts in the textual modality alone. Overall, we highlight the overall potential for a mutually beneficial relationship between the two fields. (shrink)

Peer review of journal submissions has become one of the most important pillars of quality management in academic publishing. Because of growing concerns with the quality and effectiveness of the system, a host of enthusiastic innovators has proposed and experimented with new procedures and technologies. However, little is known about whether these innovations manage to convince other journal editors. This paper will address open questions regarding the implementation of new review procedures, the occurrence rate of various peer review procedures and (...) their distribution over scientific disciplines or academic publishers, as well as the motivations for editors or publishers to engage in novel review procedures. It shows that in spite of enthusiastic innovation, the adoption of new peer review procedures is in fact very slow, with the exception of text similarity scanners. For now, peer review innovations appear to be restricted to specific niches in academic publishing. Analysing these niches, the article concludes with a reflection on the circumstances in which innovations might be more widely implemented. (shrink)

Dans une première partie, nous citerons les écrits qui racontent les « premiers contacts » entre Français et Polynésiens (1768, 1787). On y voit de fortes contradictions entre les conclusions généralisantes publiées, portant sur la liberté sexuelle pré maritale, dans un culte constant de l’amour pratiqué en public, et certains faits pourtant évoqués dans les journaux de bord : des présentations sexuelles forcées de très jeunes filles apeurées. Dans la deuxième partie, nous tenterons de comprendre cet aveuglement : il est (...) dû à la vision européenne masculine d’alors sur la nature des femmes, et à un schéma racial déjà installé qui octroya par avance aux Polynésiennes la beauté de femmes « presque blanches ».

A far-reaching reinterpretation of Plato’s Timaeus and its engagement with time, eternity, body, and soul that in its original French edition profoundly influenced Derrida The Tomb of the Artisan God provides a radical rereading of Timaeus, Plato’s metaphysical text on time, eternity, and the relationship between soul and body. First published in French in 1995, the original edition of Serge Margel’s book included an extensive introductory essay by Jacques Derrida, who drew on Margel’s insights in developing his own concepts (...) of time, the promise, the world, and khōra. Now available in English with a new preface by Margel, this engagement with Platonic thought proceeds from two questions that span the history of philosophy: What is time? What is the body? Margel’s twinned interrogation centers around Plato’s concept of the demiurge (divine artisan or craftsman): its body, its anthropomorphic attributes, its productive capacities and regulatory functions in the ordering/organization/assembling of the world. He posits that this paradoxical figure is not merely a cosmological metaphor for the living body but also the site of its destruction, dissolution, and disappearance. Torn between the finite and the infinite, being and becoming, the concept of demiurge also poses metaphysical questions about time, time before time, and the end of time. The ontological status of the demiurge’s body, Margel argues, would become increasingly decisive in the history of philosophy, particularly in Christianity and the dogma of incarnation. (shrink)
