DOWNLOAD EBOOKThe French mathematician René Thom (Fields medal 1958) died in 2002. In this volume his contributions to biology, semiotics and linguistics are discussed by a group of scholars who have continued his work and have shaped the new paradigm of dynamic semiotics and linguistics. Thom's heritage is full of revolutionary ideas and deep insights which stem from a rich intuition and a sharp awareness of the current state of the sciences, including their potentials and risks. The contributions to this volume are elaborations of papers given at a colloquium at the International Center for Semiotics and Linguistics of the University of Urbino (Italy), in 2005. The central concern of this volume is semiogenesis, i.e. the evolution and differentiation of meaningful («pregnant») forms in the field of symbolic systems - from bio-communication to language and cultural forms like music, art, architecture or urban forms. The basic questions are: How are meanings created and further differentiated? Where do they come from? What kind of forces drive their unfolding? How can complex cultural forms be understood based on simple morphodynamic principles? Applications concern the perception of forms by animals and humans, the categorization of forms e.g. in a lexicon, and predication or other complex symbolic behaviors which show up in grammar or in cultural artifacts like the unfolding of urban centers.

DOWNLOAD EBOOKThis book describes several mathematical models of the primary visual cortex, referring them to a vast ensemble of experimental data and putting forward an original geometrical model for its functional architecture, that is, the highly specific organization of its neural connections. The book spells out the geometrical algorithms implemented by this functional architecture, or put another way, the “neurogeometry” immanent in visual perception. Focusing on the neural origins of our spatial representations, it demonstrates three things: firstly, the way the visual neurons filter the optical signal is closely related to a wavelet analysis; secondly, the contact structure of the 1-jets of the curves in the plane (the retinal plane here) is implemented by the cortical functional architecture; and lastly, the visual algorithms for integrating contours from what may be rather incomplete sensory data can be modelled by the sub-Riemannian geometry associated with this contact structure. As such, it provides readers with the first systematic interpretation of a number of important neurophysiological observations in a well-defined mathematical framework. The book’s neuromathematical exploration appeals to graduate students and researchers in integrative-functional-cognitive neuroscience with a good mathematical background, as well as those in applied mathematics with an interest in neurophysiology.

DOWNLOAD EBOOKThis volume serves as a reference on the field of cognitive semantics. It offers a systematic and original discussion of the issues at the core of the debate in semiotics and the cognitive sciences. It takes into account the problems of representation, the nature of mind, the structure of perception, beliefs associated with habits, social cognition, autism, intersubjectivity and subjectivity. The chapters in this volume present the foundation of semiotics as a theory of cognition, offer a semiotic model of cognitive integration that combines Enactivism and the Extended Mind Theory, and investigate the role of imagination as the origin of perception. The author develops an account of beliefs that are associated with habits and meaning, grounded in Pragmatism, testing his Narrative Practice Semiotic Hypothesis on persons with autism spectrum disorders. He also integrates his ideas about the formation of the theory of mind with a theory of subjectivity, understood as self-consciousness which derives from semiotic cognitive abilities. This text appeals to students, professors and researchers in the field.

DOWNLOAD EBOOKThis contributed volume gives access to semiotic researches adopting a quantitative stance. European semiotics is traditionally based on immanent methodologies: meaning is seen as an autonomous dimension of human existence, whose laws can be investigated via purely qualitative analytical and reflexive analysis. Today, researches crossing disciplinary boundaries reveal the limitations of such an homogeneous practice. In particular, two families of quantitative research strategies can be identified. On the one hand, researchers wish to naturalize meaning, by making semiotic results interact with those coming from Neurophysiological and psychological sciences. On the other hand, statistical and computational tools are adopted to work on linguistic and multimedia corpora. The book acts to put the two approaches into dialogue.

DOWNLOAD EBOOKRené Thom, the famous French mathematician and founder of catastrophe theory, considered linguistics an exemplary field for the application of his general morphology. It is surprising that physicists, chemists, biologists, psychologists and sociologists are all engaged in the field of catastrophe theory, but that there has been almost no echo from linguistics. Meanwhile linguistics has evolved in the direction of René Thom’s intuitions about an integrated science of language and it has become a necessary task to review, update and elaborate the proposals made by Thom and to embed them in the framework of modern semantic theory.

DOWNLOAD EBOOKThe prison is a recent invention, hardly more than two centuries old, yet it has become the universal system of punishment. How can we understand the place that the correctional system occupies in contemporary societies? What are the experiences of those who are incarcerated as well as those who work there? To answer these questions, Didier Fassin conducted a four-year-long study in a French short-stay prison, following inmates from their trial to their release. He shows how the widespread use of imprisonment has reinforced social and racial inequalities and how advances in civil rights clash with the rationales and practices used to maintain security and order. He also analyzes the concerns and compromises of the correctional staff, the hardships and resistance of the inmates, and the ways in which life on the inside intersects with life on the outside. In the end, the carceral condition appears to be irreducible to other forms of penalty both because of the chain of privations it entails and because of the experience of meaninglessness it comprises. Examined through ethnographic lenses, prison worlds are thus both a reflection of society and its mirror. At a time when many countries have begun to realize the impasse of mass incarceration and question the consequences of the punitive turn, this book will provide empirical and theoretical tools to reflect on the meaning of punishment in contemporary societies.

DOWNLOAD EBOOKIn 1767, two “princes” of a ruling family in the port of Old Calabar, on the slave coast of Africa, were ambushed and captured by English slavers. The princes, Little Ephraim Robin John and Ancona Robin Robin John, were themselves slave traders who were betrayed by African competitors—and so began their own extraordinary odyssey of enslavement. Their story, written in their own hand, survives as a rare firsthand account of the Atlantic slave experience. Randy J. Sparks made the remarkable discovery of the princes’ correspondence and has managed to reconstruct their adventures from it. They were transported from the coast of Africa to Dominica, where they were sold to a French physician. By employing their considerable language and interpersonal skills, they cleverly negotiated several escapes that took them from the Caribbean to Virginia, and to England, but always ended in their being enslaved again. Finally, in England, they sued for, and remarkably won, their freedom. Eventually, they found their way back to Old Calabar and, evidence suggests, resumed their business of slave trading. The Two Princes of Calabar offers a rare glimpse into the eighteenth-century Atlantic World and slave trade from an African perspective. It brings us into the trading communities along the coast of Africa and follows the regular movement of goods, people, and ideas across and around the Atlantic. It is an extraordinary tale of slaves’ relentless quest for freedom and their important role in the creation of the modern Atlantic World.
