Let M be an o-minimal expansion of a real closed field. Let G be a definably compact definably connected abelian n-dimensional group definable in M. We show the following: the o-minimal fundamental group of G is isomorphic to ℤn; for each k>0, the k-torsion subgroup of G is isomorphic to n, and the o-minimal cohomology algebra over ℚ of G is isomorphic to the exterior algebra over ℚ with n generators of degree one.

Here we prove the existence of sheaf cohomology theory in arbitrary o-minimal structures.

Let R be an o-minimal expansion of an ordered group R has no poles, R cannot define a real closed field with domain R and order R is eventually linear and every R -definable set is a finite union of cones. As a corollary we get that Th has quantifier elimination and universal axiomatization in the language with symbols for the ordered group operations, bounded R -definable sets and a symbol for each definable endomorphism of the group.

Suppose G is a definably connected, definable group in an o-minimal expansion of an ordered group. We show that the o-minimal universal covering homomorphism equation image: equation image→ G is a locally definable covering homomorphism and π1 is isomorphic to the o-minimal fundamental group π of G defined using locally definable covering homomorphisms.

We show that if G is a definably compact, definably connected definable group defined in an arbitrary o-minimal structure, then G is divisible. Furthermore, if G is defined in an o-minimal expansion of a field, k ∈ ℕ and pk : G → G is the definable map given by pk = xk for all x ∈ G , then we have |–1| ≥ kr for all x ∈ G , where r > 0 is the maximal dimension of abelian (...) definable subgroups of G.

We prove that in a semi-bounded o-minimal expansion of an ordered group every non-empty open definable set is a finite union of open cells.

In this note we show: Let R = 〈R, <, +, 0, …〉 be a semi-bounded o-minimal expansion of an ordered group, and G a group definable in R of linear dimension m . Then G is a definable extension of a bounded definable group B by 〈Rm, +〉.

We show that in an o-minimal expansion of an ordered group finite definable extensions of a definable group which is defined in a reduct are already defined in the reduct. A similar result is proved for finite topological extensions of definable groups defined in o-minimal expansions of the ordered set of real numbers.

We show that in an arbitrary o-minimal structure the following are equivalent: conjugates of a definable subgroup of a definably connected, definably compact definable group cover the group if the o-minimal Euler characteristic of the quotient is non zero; every infinite, definably connected, definably compact definable group has a non trivial torsion point.

In this paper we work in an arbitrary o-minimal structure with definable Skolem functions and prove that definably connected, locally definable manifolds are uniformly definably path connected, have an admissible cover by definably simply connected, open definable subsets and, definable paths and definable homotopies on such locally definable manifolds can be lifted to locally definable covering maps. These properties allow us to obtain the main properties of the general o-minimal fundamental group, including: invariance and comparison results; existence of universal locally (...) definable covering maps; monodromy equivalence for locally constant o-minimal sheaves – from which one obtains, as in algebraic topology, classification results for locally definable covering maps, o-minimal Hurewicz and Seifert–van Kampen theorems.

Within siting literature there is strong agreement that compensation for environmental risks is a necessary condition for local acceptance of waste treatment facilities. In-kind compensation is commonly pushed forward as being more effective than financial benefits in reducing local opposition. By forcusing on the siting of a sanitary landfill in Santiago, Chile, this paper explores the performance of both types of compensation and relates the analysis to the notion of social norms of exchange. These are understood as being based on (...) three main types of social relations: care, justice and freedom. Whereas monetary compensation is associated with market relations based on freedom and the offer of in-kind compensation to egalitarian relations based on justice, the absence of compensation is linked to fraternal relations based on care. It is argued that in-kind compensation is more acceptable than monetary payments or not compensation because people tend to understand siting conflicts more as matters of justice rather than as matters of freedom or care.

To reduce ambiguity across a conversation, interlocutors reach temporary conventions or referential precedents on how to refer to an entity. Despite their central role in communication, the cognitive underpinnings of the interpretation of precedents remain unclear, specifically the role and mechanisms by which information related to the speaker is integrated. We contrast predictions of one-stage, original two-stage, and extended two-stage models for the processing of speaker information and provide evidence favoring the latter: we show that both stages are sensitive to (...) speaker-specific information. Using an experimental paradigm based on visual-world eye tracking in the context of a referential communication task, we look at the moment-by-moment interpretation of precedents and focus on the temporal profile of the influence of the speaker and linguistic information when facing ambiguity. We find two clearly identifiable moments where speaker-specific information has its effects on reference resolution. We conclude that these two stages reflect two distinct cognitive mechanisms, with different timings, and rely on different representational formats for encoding and accessing information about the speaker: a cue-driven memory retrieval process that mediates language processing and an inferential mechanism based on perspective-taking abilities.

O presente trabalho pretende responder aos diferentes problemas referentes ao conceito de temporalidade que se colocam nas obras de Levinas. O artigo faz uma perspectivação das diferentes dimensões da alteridade pessoal, em correlação com diferentes contetidos do tempo. O trabalho pretende demonstrar a novidade da articulação entre tempo e alteridade pessoal em Levinas, face a conceitos de tempo que reduzem a "dia-cronia" ao plano existentitativo, quer dizer frente a perspectivas que vivem de um conceito ontológico de tempo. /// Ce travail (...) prétend répondre à quelques problèmes qui se posent à propos du concept de temporalité chez Levinas. L'article fait une perspectivation des différentes dimensions de l'altérité personnelle en face des différents contenus du temps. Le travail prétend démontrer la nouveauté de l'articulation entre temps et altérité chez Levinas. Les positions de Levinas sur la temporalité semblent s'opposer à une vision ontologique traditionnel. /// This paper intends to answer to the problems connected with the concept of temporality, present in the work of Levinas.

It is estimated that typhoid fever (TF) annually affects more than 12 million persons, worldwide. TF is the result of a generalized infection by the enterobacterium Salmonella typhi. Patients with TF, most of whom live in developing countries have impaired activity for several weeks resulting in an important loss in productivity and welfare. Death may occur, with the single most frequent cause being intestinal perforation. While the first priority must be to develop better methods of disease prevention, there is also (...) an urgent need to devise easy, accurate, and inexpensive diagnostic assays that will allow early routine distinction of TF from other febrile illnesses. Research on TF offers the opportunity to explore many aspects of pathogenesis and the host immune response, as well as to contribute toward the development of new vaccines and diagnostic laboratory tests.

Las presentes discusiones intentarán acceder a aquel campo inmediato de la existencia en dónde nuestro cuerpo efectivamente se presenta como nuestro en una íntima relación con nuestra vida. Así, el objetivo del presente trabajo será delimitar los rasgos centrales de la cotidianeidad a partir del pensamiento de Martin Heidegger, de modo que el ámbito del despliegue concreto del fenómeno de la corporalidad pueda ser esbozado de modo existencial. En este contexto, y a partir del fenómeno de la caída, el presente (...) escrito se propondrá bosquejar cómo es que el fenómeno del cuerpo humano se manifiesta enraizado en la inmediatez de la vida fáctica.

El objetivo del presente artículo es realizar una reflexión acerca de la relación entre filosofía y ciencia a partir de los planteamientos de Martin Heidegger en los años 20. Atendiendo a las Frühe(n) Freiburger Vorlesungen, se indicará cómo es que filosofía y ciencia pueden ser entendidas como posibilidades concretas de la vida fáctica que, en última instancia, se refieren a dos tendencias existenciales particulares: la des-vivificación, por parte de la actitud teórica, perteneciente al ejercicio científico, y el intento de aprehensión (...) de la vitalidad misma de la existencia, correspondiente al ejercicio filosófico. A partir de una aclaración de ambas tendencias, el presente artículo intentará esbozar el modo cómo se podría comprender la relación entre ambas desde una perspectiva existencial. (shrink)

It is generally argued that if the wave-function in the de Broglie–Bohm theory is a physical field, it must be a field in configuration space. Nevertheless, it is possible to interpret the wave-function as a multi-field in three-dimensional space. This approach hasn’t received the attention yet it really deserves. The aim of this paper is threefold: first, we show that the wave-function is naturally and straightforwardly construed as a multi-field; second, we show why this interpretation is superior to other interpretations (...) discussed in the literature; third, we clarify common misconceptions.

Predictivists use the no miracle argument to argue that “novel” predictions are decisive evidence for theories, while mere accommodation of “old” data cannot confirm to a significant degree. But deductivists claim that since confirmation is a logical theory-data relationship, predicted data cannot confirm more than merely deduced data, and cite historical cases in which known data confirmed theories quite strongly. On the other hand, the advantage of prediction over accommodation is needed by scientific realists to resist Laudan’s criticisms of the (...) no miracle argument. So, if the deductivists are right, the most powerful argument for realism collapses. There seems to be an inescapable contradiction between these prima facie plausible arguments of predictivists and deductivists; but this puzzle can be solved by understanding what exactly counts as novelty, if novel predictions must support the no miracle argument, i.e., if they must be explainable only by the truth of theories. Taking my cues from the use-novelty tradition, I argue that (1) the predicted data must not be used essentially in building the theory or choosing the auxiliary assumptions. This is possible if the theory and its auxiliary assumptions are plausible independently of the predicted data, and I analyze the consequences of this requirement in terms of best explanation of diverse bodies of data. Moreover, the predicted data must be (2) a priori improbable, and (3) heterogeneous to the essentially used data. My proposed notion of novelty, therefore, is not historical, but functional. Hence, deductivists are right that confirmation is independent of time and of historical contingencies such as if the theorist knew a datum, used it, or intended to accommodate it. Predictivists, however, are right that not all consequences confirm equally, and confirmation is not purely a logical theory-data relation, as it crucially involves background epistemic conditions and the notion of best explanation. Conditions (1)–(3) make the difference between prediction and accommodation, and account for the confirming power of theoretical virtues such as non ad-hocness, non-fudging, non-overfitting, independence and consilience. I thus show that functional novelty (a) avoids the deductivist objections to predictivism, (b) is a gradual notion, in accordance with the common intuition that confirmation comes in degrees, and (c) supports the no miracle argument, so vindicating scientific realism.

There are two possible realist defense strategies against the pessimistic meta-induction and Laudan’s meta-modus tollens: the selective strategy, claiming that discarded theories are partially true, and the discontinuity strategy, denying that pessimism about past theories can be extended to current ones. A radical version of discontinuity realism is proposed by Gerald Doppelt: rather than discriminating between true and false components within theories, he holds that superseded theories cannot be shown to be even partially true, while present best theories are demonstrably (...) completely true. I argue that this position, running counter both the cumulativity of science and fallibilism, is untenable; it cannot account for the success of past theories, nor for the failures of current theories, and rather than shutting the door to the pessimistic historical objections it opens it wide. The best strategy, instead, joins the selective idea there was both some truth and some falsity in discarded theories, like in current ones, with the moderate discontinuity idea that the truth rate in present best theories is much greater than in past ones.

A definition of virtual or virtuality is not an easy task. Both words are of recent application in Philosophy, even if the concept of virtual comes from a respectable Latin tradition. Today’s meaning brings together the notions of potentiality, latency, imaginary representations, VR, and the forms of communication in digital media. This contagious, and spontaneous synonymy fails to identify a common vein and erases memory as a central notion. In the present essay, I’ll try to explain essential features of the (...) concept of virtual, taking the investigation of memory troubles in Pierre Janet’s work as an exemplification. Pierre Janet’s work represents a rare combination of medical observation and description of symptoms of mental illnesses, therapeutic guidance in hypnosis and philosophical writing about the main psychological themes of an epoch in transition from a Metaphysics of the Soul to the modern Experimental Psychology. Pierre Janet’s intellectual evolution since the 1880s until the end of his life is dominated by the philosophical project of a theory of the psychic system supported by three basic pillars: a concept of personality, a theory of memory and a sketch of a general theory of conduct. Such complex endeavour cannot be abstracted from the initial connections with Jean-Martin Charcot’s school at La Salpêtrière which meant a turning point in the tradition of the “animal magnetism” concerning the treatment of epileptic-hysterical symptoms along with the contributions of Hyppolite Bernheim’s “Nancy School” of hypnotism. J.-M. Charcot’s or H. Bernheim’s theorising about the organic and psychological aspects of the hypnotic treatment of the hysterical symptoms was already aware of the difficulty in dealing with the extent of the dissimulation of the patients regarding the symptoms of the illness, under hypnotic suggestion, even if Charcot insisted in the identification and cataloguing of the organic expressions, such as contractures or the posture of the body in arc during the attacks. The precise location of the “great hysteria” in the organic-psychic corridor was itself a riddle. If a symptom is a special type of sign, in the case of the “great hysteria” nobody knew for sure what it stood for. The clinical symptom of the attack stood for an organic trouble with cerebral causes, a psychological interruption of the normal sensorial and muscular movements or a disguise of the female desire? Pierre Janet described many hysterical patients, somnambulism and multiple personality since his articles in La Revue Philosophique de la France et l’ Étranger, a Journal founded by the philosopher, experimental psychologist and his intellectual predecessor Théodule-Armand Ribot. The description of the case of the “great hysterical” Lucie, treated by him, is an example of a theoretical hypothesising on multiple personality and discontinuity of memories fragments. There are more cases revealing the same relation between hysteria, somnambulism, personality dissociation and “alternating memory”. Decisively inspired by and corroborating P. Janet’s ideas, S. Freud conceived also the essential of the hysterical sicknesses as disorders of memory. The theme of memory came even more to the foreground in the dissertation L’Automatisme Psychologique. Here, the strange world of somnambulism was scrutinised along with hysterical contractures and convulsions, anaesthesia, the compulsion to repetition, obsessions, “automatic writing” in hysterical patients, multiple personality and “alternating memories”. In the depicted cases memory could not be taken as a homogenous series of remembrances or as a stock of disposable information but as a variable of the depth of the personalities’ inner formation. The so-called “seconde existence” of some somnambulists referred not only unconscious representations and unconscious thoughts but complete or inceptive latent personalities provided with multiple virtual existences and multiple memories. Hypnosis was the privileged technique to access to such multiple memories ignored by the official personality. Later and after the writing of his M.D. Dissertation, Contribution à l’ Étude des Accidents Mentaux chez les Hystériques, P. Janet addressed again the themes of memory and alternating memories in a series of lectures at the Collège de France but now according to the larger framework of a general theory of conduct which included a description of the social actions participating in the narrative construction of personal memories, and the role of social memory.

This book integrates studies on the thought of Bernard de Mandeville and other philosophers and historians of Modern Thought. The chapters reflect a rethinking of Mandeville’s legacy and, together, present a comprehensive approach to Mandeville’s work. The book is published on the occasion of the 300 years that have passed since the publication of the Fable of the Bees. Bernard de Mandeville disassembled the dichotomies of traditional moral thinking to show that the outcomes of the social action emerge as new, (...) non-intentional effects from the combination of moral opposites, vice and virtue, in such a form that they lose their moral significance. The work of this great writer, philosopher and physician is interwoven with an awareness of the paradoxical nature of modern society and the challenges that this recognition brings to an adequate perspective on the historical world of modernity.

I want to combine two hitherto largely independent research projects, scientific understanding and mechanistic explanations. Understanding is not only achieved by answering why-questions, that is, by providing scientific explanations, but also by answering what-questions, that is, by providing what I call scientific descriptions. Based on this distinction, I develop three forms of understanding: understanding-what, understanding-why, and understanding-how. I argue that understanding-how is a particularly deep form of understanding, because it is based on mechanistic explanations, which answer why something happens in (...) virtue of what it is made of. I apply the three forms of understanding to two case studies: first, to the historical development of thermodynamics and, second, to the differences between the Clausius and the Boltzmann entropy in explaining thermodynamic processes.

Deployment Realism resists Laudan’s and Lyons’ objections to the “No Miracle Argument” by arguing that a hypothesis is most probably true when it is deployed essentially in a novel prediction. However, Lyons criticized Psillos’ criterion of essentiality, maintaining that Deployment Realism should be committed to all the actually deployed assumptions. But since many actually deployed assumptions proved false, he concludes that the No Miracle Argument and Deployment Realism fail. I reply that the essentiality condition is required by Occam’s razor. In (...) fact, there is a simpler formulation of essentiality which escapes Lyons’ criticisms and rescues the No Miracle Argument and Deployment Realism from their purported historical counterexamples: a hypothesis is essential when it has no proper parts (in Yablo’s sense) sufficient to derive the same prediction. Although essentiality so conceived cannot be detected prospectively, this is just natural, and it is not a problem but an advantage for Deployment Realism. (shrink)

The ontological models framework distinguishes ψ-ontic from ψ-epistemic wave- functions. It is, in general, quite straightforward to categorize the wave-function of a certain quantum theory. Nevertheless, there has been a debate about the ontological status of the wave-function in the statistical interpretation of quantum mechanics: is it ψ-epistemic and incomplete or ψ-ontic and complete? I will argue that the wave- function in this interpretation is best regarded as ψ-ontic and incomplete.

What does it take to understand a phenomenon ideally, or to the highest conceivable extent? In this paper, we answer this question by arguing for five necessary conditions for ideal understanding: (i) representational accuracy, (ii) intelligibility, (iii) truth, (iv) reasonable endorsement, and (v) fitting. Even if one disagrees that there is some form of ideal understanding, these five conditions can be regarded as sufficient conditions for a particularly deep level of understanding. We then argue that grasping, novel predictions, and transparency (...) are not reasonable conditions for ideal understanding. (shrink)

Chasing Reality deals with the controversies over the reality of the external world. Distinguished philosopher Mario Bunge offers an extended defence of realism, a critique of various forms of contemporary anti-realism, and a sketch of his own version of realism, namely hylorealism. Bunge examines the main varieties of antirealism - Berkeley's, Hume's, and Kant's; positivism, phenomenology, and constructivism - and argues that all of these in fact hinder scientific research. Bunge's realist contention is that genuine explanations in the sciences (...) appeal to causal laws and mechanisms that are not directly observable, rather than simply to empirical generalisations. Genuine science, in his view, is objective even when it deals with subjective phenomena such as feelings of fear. This work defends a realist view of universals, kinds, possibilities, and dispositions, while rejecting contemporary accounts of these that are couched in terms of modal logic and 'possible worlds.'.

Philosophers now seem to agree that frequentism is an untenable strategy to explain the meaning of probabilities. Nevertheless, I want to revive frequentism, and I will do so by grounding probabilities on typicality in the same way as the thermodynamic arrow of time can be grounded on typicality within statistical mechanics. This account, which I will call typicality frequentism, will evade the major criticisms raised against previous forms of frequentism. In this theory, probabilities arise within a physical theory from statistical (...) behavior of almost all initial conditions. The main advantage of typicality frequentism is that it shows which kinds of probabilities (that also have empirical relevance) can be derived from physics. Although one cannot recover all probability talk in this account, this is rather a virtue than a vice, because it shows which types of probabilities can in fact arise from physics and which types need to be explained in different ways, thereby opening the path for a pluralistic account of probabilities.
