Les médiations de la parole publique par les dispositifs numériques questionnent le renouvellement possible des formes de délibérations collectives au sein des groupes associatifs. Nous examinerons comment, dans un contexte d'émergence de nouveaux collectifs technophiles orientés vers des pratiques d'usage et de politisation des technologies de communication, le mouvement « communautaire » québécois redéfinit son identité, ses aspirations et ses pratiques dans la sphère publique, au prix de vives tensions. Plusieurs éléments semblent structurer les différences et controverses: l'enracinement local du (...) mouvement communautaire, sa structure hiérarchique, son mode de financement et les représentations de la technique.Mediations of public speaking by digital devices can question the renewal of collective forms of deliberation within voluntary groups. We will examine how, in the context of the emergence of new collective-oriented technophiles use practices and politicization of communication technologies, the movement "community" Quebec redefines its identity, its aspirations and practices in the public sphere, the price tensions. Several factors seem to structure differences and controversies: local roots community movement, its hierarchical structure, its funding and representations of the art. (shrink)

The fundamental tenet of modern empiricism is the view that all non-analytic knowledge is based on experience. Let us call this thesis the principle of empiricism. [1] Contemporary logical empiricism has added [2] to it the maxim that a sentence makes a cognitively meaningful assertion, and thus can be said to be either true or false, only if it is either (1) analytic or self-contradictory or (2) capable, at least in principle, of experiential test. According to this so-called empiricist criterion (...) of cognitive meaning, or of cognitive significance, many of the formulations of traditional metaphysics and large parts of epistemology are devoid of cognitive significance--however rich some of them may be in non-cognitive import by virtue of their emotive appeal or the moral inspiration they offer. Similarly certain doctrines which have been, at one time or another, formulated within empirical science or its border disciplines are so contrived as to be incapable of test by any conceivable evidence; they are therefore qualified as pseudo- [p. 42:] hypotheses, which assert nothing, and which therefore have no explanatory or predictive force whatever. This verdict applies, for example, to the neo-vitalist speculations about entelechies or vital forces, and to the "telefinalist hypothesis" propounded by Lecomte du Noüy. (shrink)

The military conquest of the Magarant, the Magar land, took place during the sixteenth and seventeenth centuries, when the Thakuri petty kings and their dependents (priests, artisans, soldiers) fled India to settle there. The Magar resistance appears to have been weak, due to their lack of unity and the alliances the conquerors formed with some of them. The Magar people quickly opted for assimilation into the royal caste of the Thakuri, adopting most of their cultural traits, notably their language and (...) religion. Nevertheless they retained or developed particularisms in their relationship to the earth, as we can see in the rites they devote to Bhume. We should emphasize first and foremost that the name Bhume is itself Nepalese, derived from the sanskrit bhû, bhûmî. This goddess is neglected by the Hindi of high caste, whereas she is central to the Magar. This paradox has two possible sources: the Magar might have identified one of their principal goddesses with a minor Hindu deity by virtue of a common relation to the earth, conferring an unusual importance on the latter. Or they might have constructed a divine being on the basis of Hindu concepts, as the result of a new-found need to defend their rights to the earth in the face of the Hindu invaders. The second hypothesis seems more likely, since there is no trace of a Magar earth goddess before Bhume. Even in the regions where the Magar retained the use of their original language (such as in Palpa, Syangja, or in the Kham country) and where, consequently, some of the gods have Magar names, the earth goddess is called by Nepalese terms, such as Bhume, Bhuyar, or Bhayar. Furthermore, even if the Magar themselves once had an earth goddess of their own, the renaming of this deity would indicate a change of identity, given the importance of a divinity's name. (shrink)

We study the sets of the infinite sentences constructible with a dictionary over a finite alphabet, from the viewpoint of descriptive set theory. Among others, this gives some true co-analytic sets. The case where the dictionary is finite is studied and gives a natural example of a set at level ω of the Wadge hierarchy.

We show that there is an antichain basis for neither the class of non-potentially closed Borel subsets of the plane under Borel rectangular reducibility nor the class of analytic graphs of uncountable Borel chromatic number under Borel reducibility.

In this paper, we study dialogue as a game, but not only in the sense in which there would exist winning strategies and a priori rules. Dialogue is not governed by game rules like for chess or other games, since even if we start from a priori rules, it is always possible to play with them, provided that some invariant properties are preserved. An important discovery of Ludics is that such properties may be expressed in geometrical terms. The main feature (...) of a dialogue is “convergence”. Intuitively, a dialogue “diverges” when it stops prematurely by some disruption, or a violation of the tacit agreed upon conditions of the discourse. It converges when the two speakers go together towards a situation where they agree at least on some points. As we shall see, convergence may be thought of through the geometrical concept of orthogonality . Utterances in a dialogue have as their content, not only the processes (similar to proofs) which lead to them from a monologic view, but also their interactions with other utterances. Finally, any utterance must be seen as co-constructed in an interaction between two processes. That is to say that it not only contains one speaker’s intentions but also his or her expectations from the other interlocutor. From our viewpoint, discursive strategies like narration , elaboration , topicalization may derive from such interactions, as well as speech acts like assertion, question and denegation. (shrink)

We prove that, for each countable ordinal ξ≥1, there exist some -complete ω-powers, and some -complete ω-powers, extending previous works on the topological complexity of ω-powers [O. Finkel, Topological properties of omega context free languages, Theoretical Computer Science 262 669–697; O. Finkel, Borel hierarchy and omega context free languages, Theoretical Computer Science 290 1385–1405; O.

Lecomte, Sur les ensembles de (...) phrases infinies constructibles a partir d’un dictionnaire sur un alphabet fini, Séminaire d’Initiation a l’Analyse, 1, année 2001–2002; D. Lecomte, Omega-powers and descriptive set theory, Journal of Symbolic Logic 70 1210–1232; J. Duparc, O. Finkel, An ω-Power of a Context-Free Language Which Is Borel Above , in: S. Bold, B. Löwe, T. Räsch, J. van Benthem , in the Proceedings of the international conference foundations of the formal sciences V : Infinite Games, November 26th to 29th, 2004, Bonn, Germany, in: Studies in Logic, vol. 11, College Publications at King’s College, 2007, pp. 109–122]. We prove effective versions of these results; in particular, for each recursive ordinal there exist some recursive sets A2<ω such that , where and denote classes of the hyperarithmetical hierarchy. To do this, we prove effective versions of a result by Kuratowski, describing a set as the range of a closed subset of the Baire space ωω by a continuous bijection. This leads us to prove closure properties for the pointclasses in arbitrary recursively presented Polish spaces. We apply our existence results to get better computations of the topological complexity of some sets of dictionaries considered in [D. Lecomte, Omega-powers and descriptive set theory, Journal of Symbolic Logic 70 1210–1232]. (shrink)

Developing earlier studies of the system of numbers in Mundurucu, this paper argues that the Mundurucu numeral system is far more complex than usually assumed. The Mundurucu numeral system provides indirect but insightful arguments for a modular approach to numbers and numerals. It is argued that distinct components must be distinguished, such as a system of representation of numbers in the format of internal magnitudes, a system of representation for individuals and sets, and one-to-one correspondences between the numerosity expressed by (...) the number and its metrics. It is shown that while many-number systems involve a compositionality of units, sets and sets composed of units, few-number languages, such as Mundurucu, do not have access to sets composed of units in the usual way. The nonconfigurational character of the Mundurucu language, which is related to a property for which we coin the term 'low compositionality power', accounts for this and explains the curious fact that Mundurucus make use of marked one-to-one correspondence strategies in order to overcome the limitations of the core system at the perceptual/motor interface of the language faculty. We develop an analysis of a particular construction, parallel numbers, which has not been studied before, elucidating the whole system. This analysis, we argue, sheds new light on classical philosophical, psychological and linguistic debates about numbers and numerals and their relation to language, and more particularly, sheds light on few-number languages.

Let ξ ≥ 1 be a countable ordinal. We study the Borel subsets of the plane that can be made [Formula: see text] by refining the Polish topology on the real line. These sets are called potentially [Formula: see text]. We give a Hurewicz-like test to recognize potentially [Formula: see text] sets.

The contribution of inherited non‐genetic factors to complex diseases is of great current interest. The ways in which mothers and fathers can affect their offspring's health clearly differ as a result of the intimate interactions between mother and offspring during pre‐ and postnatal life. There is, however, potential for some overlap in mechanisms, particularly epigenetic mechanisms. A small number of epidemiological studies and animal models have investigated the non‐genetic contribution of the parents to offspring health. Discovering new mechanisms of disease (...) inheritance is technically difficult, especially in genetically, socially and environmentally heterogeneous human populations. Therefore, rigorous experimental design, appropriate sample numbers and the use of high‐throughput technologies are necessary to provide convincing evidence. Based on recent examples from the literature, here we propose several ways to improve human studies that aim to identify the underlying mechanisms of transgenerational inheritance of metabolic disease.

We prove that, for any natural number \, we can find a finite alphabet \ and a finitary language L over \ accepted by a one-counter automaton, such that the \-power $$\begin{aligned} L^\infty :=\{ w_0w_1\ldots \in \Sigma ^\omega \mid \forall i\in \omega ~~w_i\in L\} \end{aligned}$$is \-complete. We prove a similar result for the class \.

The concept of modernity, according to Michel Foucault and Marcel Gauchet, is closely related to the idea of a new form of power. While Foucault analyzes power from within, Gauchet develops a theory of power based on a relation to externality. Both perceive the asylum as one of the most representative settings of this modern form of power. I show that Gauchet’s model preserves Foucault’s contribution, while giving it a new significance.

We present a formalization of some ideas from Chomsky [9] in the framework of multimodal type logical grammar.

En retraçant le parcours du Père Samaan, figure centrale de la scène chrétienne égyptienne, cet article analyse les trajectoires mouvantes de la politisation des coptes charismatiques et chrétiens évangéliques en Égypte dans les dernières années – les deux mouvances étant étroitement liées l’une à l’autre. Outre des orientations relatives à des positions de classe, des manœuvres et tactiques vis-à-vis des institutions ecclésiales, des arènes politiques locale et nationale, comme des ONG internationales, le rapport au politique des chrétiens charismatiques et évangéliques (...) d’Égypte est également conditionné par leur perception du religieux majoritaire dans le pays, à savoir l’Islam. Loin de refléter une tendance théologico-politique globale et homogène en tous lieux, partir de ce cas donne à penser la manière dont, à travers l’œuvre d’acteurs situés comme celle du Père Samaan, le christianisme charismatique s’ancre toujours dans des logiques territorialisées et des enjeux locaux.

'The problem of the twentieth-century is the problem of the color-line.' Originally published in 1903, The Souls of Black Folk is a classic study of race, culture, and education at the turn of the twentieth century. With its singular combination of essays, memoir, and fiction, this book vaulted W. E. B. Du Bois to the forefront of American political commentary and civil rights activism. The Souls of Black Folk is an impassioned, at times searing account of the situation of African (...) Americans in the United States. Du Bois makes a forceful case for the access of African Americans to higher education, memorably extols the achievements of black culture (above all the spirituals or 'sorrow songs'), and advances the provocative and influential argument that due to the inequalities and pressures of the 'race problem', African American identity is characterized by 'double consciousness'. This edition includes a valuable appendix of other writing by Du Bois, which sheds light on his attitudes and intentions. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford's commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.
