Este artículo expone algunos datos y reflexiones que se plantean como una contribución para explicar y comprender prácticas y procesos -de comunicación, inserción, organización- desplegados por migrantes africanos en Argentina. Lo anterior, prestando especial atención a la experiencia de la circulación, la inserción en redes sociales y la producción y puesta en juego de saberes específicos por parte de tales actores en territorios diversos interconectados a partir de las trayectorias migratorias. Tales aportes se desprenden de poner en diálogo resultados del (...) trabajo realizado en dos proyectos de investigación en curso -con inserción en la Université Lumière de Lyon 2 y en la Universidad Nacional de La Plata (UNLP), respectivamente-, que indagan, a través de aproximaciones etnográficas con objetivos diferentes, el fenómeno de una nueva corriente migratoria desde diversos países de África en Argentina (América del Sur). El relevamiento de campo es desarrollado a partir de entrevistas, conversaciones informales y observación participante en espacios de la vida cotidiana de migrantes africanos, en su mayoría de nacionalidad senegalesa, arribados al país en la última década y con residencia en las ciudades de Buenos Aires y La Plata.

We extend some of the classical connections between automata and logic due to Büchi  and McNaughton and Papert  to languages of finitely varying functions or “signals”. In particular, we introduce a natural class of automata for generating finitely varying functions called ’s, and show that it coincides in terms of language definability with a natural monadic second-order logic interpreted over finitely varying functions Rabinovich . We also identify a “counter-free” subclass of ’s which characterise the first-order definable languages (...) of finitely varying functions. Our proofs mainly factor through the classical results for word languages. These results have applications in automata characterisations for continuously interpreted real-time logics like Metric Temporal Logic Chevalier et al.  and . (shrink)
The present research isolates the fairness assessment of the process used by the retailer to set a price, as well as the distributive fairness of the price compared to the price that others are offered, and examines the combined effect of procedural fairness and distributive fairness on overall price fairness. Two experimental studies examine procedural and distributive fairness effects on overall price fairness. In study 1, procedural fairness and distributive fairness are manipulated and found to interact to bring about overall (...) price fairness. In study 2, suspicion toward the seller is found to mediate the relationship between procedural fairness and overall price fairness when the price is disadvantageous. (shrink)
Times of crisis bring about increased demands on businesses as shortages, or unexpected but significant, business costs are encountered. Passing on such costs to consumers is a challenge. When faced with a retail price increase, consumers may rely on cues as to the motive behind the increase. Such cues can raise suspicion of alternative motive (e. g., taking advantage of the consumer) affecting consumers' judgments of price fairness. This research investigates two triggers of suspicion: salience of alternative motives, and behavior (...) judged to be out-of-character for the business. Results of the two studies within crisis contexts indicate that suspicion is created when alternative motives are salient and when a retailer acts out-of-character. Multiple group analyses revealed that suspicion induced negative affect and subsequent perceptions of price fairness. When suspicion was present, more negative feelings toward the retailer and judgments of price unfairness resulted. (shrink)
Le philosophe américain Charles S. Peirce ne trouva, malgré ses efforts, guère d'interlocuteurs en France. On le considéra comme un mathématicien et logicien, un physicien et un psychologue fiable, mais son œuvre philosophique fut systématiquement distordue au gré des controverses franco-françaises. Nous mettons l'accent sur les lectures d'André Lalande et de Louis Couturat qui contribuèrent néanmoins à faire reconnaître en France l'originalité du père du pragmaticisme. Despite his efforts, the American philosopher Charles S. Peirce found hardly any interlocutors in France. (...) He was considered mostly as a mathematician and logician, a physicist and a reliable psychologist, but his philosophical work was systematically distorted in consequence of "Franco-French" disputes. We emphasize here the readings of André Lalande and Louis Couturat who made significant contributions towards the recognition in France of the originality of the founding father of Pragmaticism.

We study the idea of implantation of Piron's and Bell's geometrical lemmas for proving some results concerning measures on finite as well as infinite-dimensional Hilbert spaces, including also measures with infinite values. In addition, we present parabola based proofs of weak Piron's geometrical and Bell's lemmas. These approaches will not used directly Gleason's theorem, which is a highly non-trivial result.
- How can anthropology improve our understanding of the interrelationship between nature and culture? - What can anthropology contribute to practical debates which depend on particular definitions of nature, such as that concerning sustainable development? Humankind has evolved over several million years by living in and utilizing 'nature' and by assimilating it into 'culture'. Indeed, the technological and cultural advancement of the species has been widely acknowledged to rest upon human domination and control of nature. Yet, by the 1960s, the (...) idea of culture in confrontation with nature was being challenged by science, philosophy and the environmental movement. Anthropology is increasingly concerned with such issues as they become more urgent for humankind as a whole. This important book reviews the current state of the concepts of 'nature' we use, both as scientific devices and ideological constructs, and is organised around three themes: - nature as a cultural construction; - the cultural management of the environment; and - relations between plants, animals and humans.

We consider weighted o-minimal hybrid systems, which extend classical o-minimal hybrid systems with cost functions. These cost functions are “observer variables” which increase while the system evolves but do not constrain the behaviour of the system. In this paper, we prove two main results: optimal o-minimal hybrid games are decidable; the model-checking of WCTL, an extension of CTL which can constrain the cost variables, is decidable over that model. This has to be compared with the same problems in the framework (...) of timed automata where both problems are undecidable in general, while they are decidable for the restricted class of one-clock timed automata.

ABSTRACT : Alfred Fouillee's doctrine of ideas-forces approximates historically and intellectually William James’s theory of will. But Fouillee's criticism of pragmatism also has connections with Pierce's emphasis on the real and the analysis of concepts, and shows an influence of tychism approaching mysticism. -/- .
The evidence for a panhuman, cognitively rooted, essence-based concept of basic natural kind and for certain prototypical phenomenal forms is increasingly compelling, but there remain doubts as to whether these two elements combine with a principle of taxonomy to form a unified, domain-specific theory in the way Atran claims. The appropriateness of the notion of meme can also be questioned, as can the assertion that humans are always grouped in ethnobiological classifications in unambiguous contrast to other animals.
Rosenberg claims that economics must use the 'intentional idiom' for its explanatory strategies. We examine whether scientific articles in financial economics do in fact ascribe propositional attitudes to economic agents. We look at articles in the Journal of Finance , volume 54 (1999), where we find a total of 250 502 words in 29 articles. The total number of ascriptions of the intentional states of belief, desire, expectation or preference to economic agents is 137, with 26 of 29 articles making (...) 10 or fewer ascriptions. We propose other areas where intentionality might be found in these articles. (shrink)
Parés de leur évidence technologique, les dispositifs de communication en ligne des plate-formes d'EAD et de travail collaboratif proposés dans le cadre de la coopération Nord-Sud constituent un environnement non questionné. Le rôle qui leur est dévolu dans la co-construction et le partage des savoirs ne doit pas faire oublier leur nature très souvent idéologique : une approche néo-libérale de la formation, du travail collaboratif, qui est caractérisée par l'indistinction des valeurs, une naturalisation des lois du marché appliquées aux biens (...) culturels. C'est une grande prudence qui doit accompagner ces transferts de compétences.Online mechanisms of e-learning devices and collaborative work proposed in the frame of North-South cooperation possess clear technological value and constitute an unquestioned environment. The important role that has been attributed to them in the co-construction and the sharing of knowledge must not lead us to forget their very nature. This nature is is very often ideological: a neoliberal approach to training and to cooperative work which is distinguished by the confusion of values and the naturalization of the laws of the market applied to cultural property. Great care must therefore be taken with these skill transfers. (shrink)
Zusammenfassung Ellen M. Wood hat mit ihrer Studie „Retreat from Class. A ‚new true socialism“ bereits 1986 eine überzeugende Kritik des Postmarxismus vorgelegt. Der Artikel zeichnet deren zentrale Punkte nach und zeigt, dass diese auf einer innovativen Interpretation des historischen Materialismus beruhen, die als ‚politischer Marxismus‘ bezeichnet wird. Gleichwohl bleibt zu fragen, ob Woods Kritik nicht zugleich Annahmen des klassischen Marxismus reproduziert, die historisch wie systematisch zweifelhaft sind.
Cet article montre que le Livre du Chevalier errant de Thomas iii de Saluces est un miroir familial visant, à travers la combinaison du souvenir historique et de la fiction légendaire, à sublimer le souvenir des aïeux. Dans cette stratégie d’exaltation généalogique, le rôle des femmes est loin d’être négligeable. Deux cas remarquables d’héroïsme féminin sont analysés, ceux de Richarde de Saluces, la guerrière, et de Grisilidis, l’épouse vertueuse.
Much work has recently been done on Jane Addams, her writings, and the general atmosphere and thought associated with Hull House and other settlement places in American cities.1 But although we might think of Addams and her work as the center of the Hull House effort, many other women (and a few men) were involved in the efforts, and the strengths that they brought to bear on the activities in Chicago in the early part of the twentieth century need to (...) be delineated and, to some extent, given pride of place. Two women whose work was applauded by Addams at the time, but whose thought remains somewhat under investigated are Ellen Gates Starr and Julia Lathrop. Indeed, Addams wrote a book about her partnership with .. (shrink)
Imagine a citizen (call her Ellen) engages in conduct the state says is a crime, for example, money laundering. Imagine too that the state of which Ellen is a citizen has decided to make money laundering a crime. Does the state wrong Ellen when it punishes her for money laundering? It depends on what you think about the authority of the criminal law. Most criminal law scholars would probably say that the criminal law as such has no (...) authority. Whatever authority is has depends on how well it adheres to the demands of morality inasmuch as morality is the only authority we have. Thus if morality says that money laundering should not be a crime then the state wrongs Ellen when it punishes her. But if the criminal law as such does have authority, and if in the exercise of its authority the state has decided to make money laundering a crime, then the state does Ellen no wrong when it punishes her.

The field of narrative medicine holds that personal narratives about illness have the potential to give illness meaning and to create order out of disparate facets of experience, thereby aiding a patient’s treatment and resisting universalizing medical discourse. Two narratives of bipolar disorder, Kay Redfield Jamison’s prose memoir An Unquiet Mind and Ellen Forney’s graphic memoir Marbles challenge these ideas. These writers demonstrate that one result of bipolar disorder is a rupture to their sense of identity, making straightforward and (...) verbal forms of narrative impossible. During periods of relative mood stability, reliable memories of mania or depression are equally impossible. As a result, these memoirists seek to develop sources of self-knowledge other than memory and introspection, long the foundations of personal narrative. Finally, An Unquiet Mind and Marbles return attention to questions of selfhood at a time when scholarship on memoir rejects interpretations of life stories as clear and reliable expressions of identity.
