Written in the form of a dialogue with Brussels sociologist Dieter Vandebroeck, this article retraces the social and intellectual trajectory of Loïc Wacquant as stepping stone to reviewing and discussing the major concepts coined and theoretical propositions elaborated in the course of his research on comparative urban marginality, racial domination, the ghetto, the penal state, neoliberalism, and carnality. This provides an opportunity to specify the relationships between ethnography, history and theory; the dialectic of domination and resistance; the role of (...) public (dis)honor in social life; the uses of Bourdieu's bureaucratic field; and the social and academic conditions of incubation, diffusion, and death of scholarly myths such as the “underclass.” The article closes on a call to clearly distinguish the rhetorical, metaphorical, and analytical usages of concepts and reaffirms the need for epistemic reflexivity as sine qua non for the articulation of robust scientific problematics.

I use the collection of “carnal ethnographies” of martial arts and combat sports assembled by Raul Sanchez and Dale Spencer under the title Fighting Scholars to spotlight the fruitfulness of deploying habitus as both empirical object (explanandum) and method of inquiry (modus cognitionis). The incarnate study of incarnation supports five propositions that clear up tenacious misconceptions about habitus and bolster Bourdieu’s dispositional theory of action: (1) far from being a “black box,” habitus is fully amenable to empirical inquiry; (2) the (...) distinction between primary (generic) and secondary (specific) habitus enables us to capture the malleability of dispositions; (3) habitus is composed of cognitive, conative and affective elements: categories, skills, and desires; (4) habitus allows us to turn carnality from problem to resource for the production of sociological knowledge; and (5) thus to realize that all social agents are, like martial artists, suffering beings collectively engaged in embodied activities staged inside circles of shared commitments.

Véronique Adam : Les neurosciences ne s’intéressent que depuis très récemment à l’olfaction. Pourriez‑vous expliquer pourquoi ce sens est devenu un objet d’étude plus prégnant? Jean-Louis Millot : En fait, l’olfaction demeure encore peu étudiée comparée à d’autres modalités sensorielles. De manière générale, les neurosciences cognitives actuelles, comme d’autres investigations scientifiques chez l’homme par le passé, se focalisent davantage sur les compétences cognitives complexes, telles qu...

In this response to my critics, I amplify the conceptual clarification and methodological stipulation of habitus begun in ‘Homines in extremis’ to help us move from a sociology of the body as socially construc-ted object to a sociology from the body as socially construc-ting vector of knowledge, power, and practice. The specification of habitus by membership in collectives, attachment to institutions, and analytic purpose makes it a flexible multi-scalar notion with which to construct the epistemic individual and account for both (...) reproduction and change, conformity and creativity, as well as self-revision. For this, we must reject theological interpretations that rigidly lock habitus into Bourdieu’s framework; avoid conflating the formal properties of the notion with its concrete features in specific settings and cases; and distinguish between the rhetorical invocation of his concepts (‘speaking Bourdieuese’) and their effective deployment in the construction of the empirical object. As embodied and embedded capacity, habitus brings temporality, depth, and desire to the analytic epicenter. It reminds us that the social world is not transparent, open-ended, and instantaneous, but endowed with gravity, opacity, and asymmetry. Treating the sentient and skilled organism as fount of both social intelligence and sociological acumen can help historical social science connect with enactive psychology and recover the carnality of action that conventional accounts of social life routinely erase.

The comparative sociology of the structure, dynamics, and experience of urban relegation in the United States and the European Union during the past three decades reveals the emergence of a new regime of marginality. This regime generates forms of poverty that are neither residual, nor cyclical or transitional, but inscribed in the future of contemporary societies insofar as they are fed by the ongoing fragmentation of the wage labour relationship, the functional disconnection of dispossessed neighbourhoods from the national and global (...) economies, and the reconfiguration of the welfare state in the polarizing city. Based on a methodical comparison between the black American ghetto and the French working-class banlieue at century's turn, this article spotlights three distinctive spatial properties of `advanced marginality' — territorial fixation and stigmatization, spatial alienation and the dissolution of `place', and the loss of a hinterland — and draws out their implications for the formation of the `precariat' in postindustrial societies.

We propose that interaction rules derived from polyamine exchange in connected cells may explain the spatio‐temporal organization of gap junctions observed during tissue regeneration and tumorigenesis. We also hypothesize that polyamine exchange can be considered as signal that allows cells to sense the proliferation status of their neighbors. Polyamines (putrescine, spermidine, and spermine) are indeed small aliphatic polycations that serve as fuels to sustain elevated proliferation rates of the order observed in cancer cells. Based on recent reports, we consider here (...) that polyamines can be exchanged through gap junction channels between mammalian cells. Such intercellular exchange of polyamines has critical consequences on the local control of growth. In line with this hypothesis, the complex protein network that keeps polyamine levels finely tuned in mammalian cells can translate polyamine efflux or influx into integrated signals controlling transcription, translation, and cell communications.

This paper reflects on the notion of partial ambiguity. Using a framework decomposing ambiguity into distinct layers of analysis, among which are risk and model uncertainty, and allowing for different attitudes toward these layers, I show that partial ambiguity may prove less desirable than full ambiguity, even under ambiguity aversion. This observation poses difficulties for interpreting the notion of partial ambiguity in relation to the partial information available to determine the potential compositions of an ambiguous urn. Two Ellsberg-style thought experiments (...) are described to challenge the meaning of partial ambiguity further, and an alternative interpretation, based on a more ambiguous relation, is discussed.

Pourquoi les STAPS (Sciences et Techniques des Activités Physiques et Sportives), discipline universitaire et de recherche sont-elles fragmentées en une multitude de programmes et de sous-programmes? Qui est-ce qui assure le succès général des sports comme contenus d'éducation physique scolaire et explique l'accueil extrêmement favorable qui leur est fait dans nos sociétés? Les STAPS peuvent-elles être une science?

In the field of NLP, “noise” is a notion with many different meanings. This is also true in fields of linguistics in which the analysis of ecological data is central.In studies involving corpus linguistic methods, noise management is an essential process for data collection, data structuration and data analysis. Paradoxically, this step is almost never developed, or completely ignored.In this paper, we propose to focus on the management of noise during the various stages classically defined in the processing of an (...) oral corpus: data structuration (including transcription), data enrichment (including annotation) and data analysis.We show that noise management is a cross-cutting issue: it needs to be taken into account during the phases of structuration, data enrichment and analysis of linguistic corpora. More specifically, the creation of corpora of children’s productions leads us to manage a particular type of noise: the variation regarding the so-called “standard” forms. For noise management, we show that there is no ideal methodology: noise management is specific to each project. Moreover, decisions taken at one stage necessarily influence the others: a noise generated during data structuration may cause a silence during automatic processing; a noise “cleaned up” during the processing phase may generate a silence during analysis.

Résumé Cet article présente l’analyse d’une expérience de construction de savoirs mathématiques en rapports avec les machines, dans les années 1950 et 1960, à une époque où le calcul analogique cohabitait avec le calcul digital (c’est-à-dire le futur « ordinateur », terme introduit dans la langue française pour désigner principalement les « digital computers »). Les mathématiques en jeu relèvent des théories des systèmes dynamiques, c’est-à-dire des outils mathématiques construits pour comprendre la dynamique de différents types de systèmes, qu’ils soient (...) mathématiques, physiques, biologiques, mécaniques, etc. L’objet du présent article est à la fois un groupe de chercheurs, leurs pratiques de « mathématiques pour l’ingénieur », leurs efforts pour construire des calculateurs analogiques (mécanique ou électronique) pour étudier la dynamique, le programme baptisé « Dynamique théorique » qu’ils se sont fixés, et l’épistémologie des mathématiques sous-tendant leur pratique.

¿Qué debe a Pascal la gran obra de Bourdieu, las Meditaciones Pascalianas ? ¿Cómo presentar la referencia a Pascal en un sociólogo como Bourdieu?..

This article draws on 35 months of ethnographic fieldwork and apprenticeship in a boxing gym located in Chicago's black ghetto to explicate how prizefighters apperceive and express the fact of being live commodities of flesh and blood, and how they practically reconcile themselves to ruthless exploitation in ways that enable them to maintain a sense of personal integrity and moral purpose. The boxer's experience of corporeal exploitation is expressed in three kindred idioms, those of prostitution, slavery and animal husbandry. The (...) first likens the fighter-manager combo to the prostitute-pimp duo; the second depicts the ring as a plantation and promoters as latter-day slave masters; the third intimates that boxers are used in the manner of livestock. All three tropes simultaneously enounce and denounce the immoral marketing of disquiescent bodies. But this acute consciousness is neutralized by the doxic belief in the normalcy of exploitation, in the `agency' of corporeal entrepreneurship, and in the possibility of individual exceptionalism. This practical belief, inscribed in the bodily dispositions of the fighter, helps produce the collective misrecognition whereby boxers collude in their own commercialization. (shrink)

This article reflects on the international reception of my book Prisons of Poverty as revelator of penal developments in advanced societies over the past decade. I show that the global firestorm of law and order inspired by the United States that the book detected in 1999 has continued to rage far and wide. Indeed, it has extended from First- to Second-World countries and has altered punishment politics and policies around the globe in ways that no one foresaw and would have (...) thought possible two decades ago. I extend the analysis of the role of think tanks (especially the Manhattan Institute) in the diffusion of US-style crime-fighting notions and nostrums in Latin America as one element of the international circulation of pro-market policy packages fostering the punitive management of poverty. I elaborate and revise the original model of the link between neoliberalism and punitive penality, leading to the analysis of state-crafting in the age of social insecurity developed in my book Punishing the Poor.

Drawing on the Begriffsgeschichte of Reinhart Koselleck and the reflexive sociology of Pierre Bourdieu, my book The Invention of the ‘Underclass’ draws a microhistory of the birth, diffusion, and demise of this racialized folk devil at the intersection of the academic field, the journalistic field, and the politics-policy-philanthropic field. This history illuminates the politics of knowledge about dispossessed and dishonored categories in the metropolis and suggests three notions that can help researchers parse the use and abuse of other social science (...) constructs and thus practice better conceptual hygiene: lemming effects (illustrated by the wild rush to deploy ‘diaspora’), conceptual speculative bubble (as with ‘racial capitalism’), and turnkey problematics (such as the ‘resilient city’ and the ‘creative city’). I discuss the factors that foster the development of epistemic bandwagons, speculation, and turnkeys, and specify the criteria that make for a robust concept in terms of semantics (clarity and neutrality), logics (coherence and type-specificity), and heuristics (empirical adequacy and theoretical productivity).

Most decisions concerning insurance and self-protection have to be taken in situations in which the effort exerted precedes the moment uncertainty realizes, and the probabilities of future states of the world are not perfectly known. By integrating these two characteristics in a simple theoretical framework, this paper derives plausible conditions under which ambiguity aversion raises the demand for insurance and self-protection. In particular, it is shown that in most usual situations where the level of ambiguity does not increase with the (...) level of effort, a simple condition of ambiguity prudence known as decreasing absolute ambiguity aversion is sufficient to give a clear and positive answer to the question: Does ambiguity aversion raise the optimal level of effort?

This paper deals with the two notions of aition or aitia and prophasis in the Greek medical texts and asks the question of whether these words are synonymous or not. Therefore, it explores their different meanings in different contexts both in the Hippocratic and in the Galenic corpus. It also investigates how Galen understands these two notions when he reads them in the Hippocratic treatises and how he explains them in his commentaries to Hippocrates, and in particular, if he gives (...) the same meaning to these words in his own treatises or if he uses them in a different way.

En partant des quatre uniques emplois d’ agèrasia recensés dans l’ensemble de la littérature grecque, et en s’attachant à clarifier les liens entretenus entre agèrasia et athanasia (immortalité), mais aussi entre agèrasia et eugèria (belle vieillesse), on s’efforcera de définir quelles représentations exactes de la vieillesse véhicule le recours à ce vocabulaire, à la fois chez un médecin comme Galien et chez des philosophes comme Aristote et Philon d’Alexandrie.

The agronomist who wants to study the nutrient and water uptake of roots needs a quantitative three-dimensional dynamic model of the structure of root systems.The model presented takes into account current knowledge about the morphogenesis of root systems. It describes the root system as a set of root axes, characterised by their orders. The morphogenetic properties of root axes differ according to their order. The axes of order 1 are directly inserted on the stem, the axes of order 2 are (...) inserted on axes of order 1, and so on. They tend to be more plagiotropec and to have less vascular bundles as the order increases. (shrink)

L'articolo, che sintetizza le tesi esposte in Punishing the Poor, tenta di elaborare una teoria dello Stato all'epoca del neoliberismo. Secondo l'autore, le politiche economiche restrittive basate sullo sfruttamento del lavoro dequalificato e sullo sgretolamento delle acquisizioni sociali, da un lato, e la svolta securitaria e penitenziaria nella gestione della criminalitÀ, dall'altro, rappresentano le due facce della stessa medaglia. Quel che ne emerge č una visione sommamente contradditoria dello Stato: decisamente liberale in sede economica e tollerante verso le élite; profondamente (...) attivo e violento in ambito giuridico e nei confronti degli ultimi.

Rastreando los orígenes filosóficos y el uso inicial por Pierre Bourdieu de habitus para dar cuenta de la disyunción histórica producida por la guerra argelina de liberación nacional y por la modernización de posguerra del campo francés, podemos clarificar cuatro errores de comprensión recurrentes sobre el concepto: (1) el habitus no es nunca la réplica de una simple estructura social sino un set de esquemas de muchas capas, multiescalar y dinámico sujeto a “revisión permanente” en la práctica; (2) el habitus (...) no es necesariamente coherente y unificado sino que presenta grados variables de integración y tensión; (3) porque no es siempre congruente con el cosmos en que se desarrolla y despliega, el habitus es tan apropiado para analizar crisis y cambio como cohesión y continuidad; pero (4) no es un mecanismo autosuficiente para la generación de acción: la disección de disposiciones debe proceder siempre en conexión cercana con el mapeo del sistema de posiciones que alternadamente excita, suprime o redirecciona las inclinaciones y capacidades socialmente constituidas del agente. De modo crucial, en manos de Bourdieu, habitus no es un concepto abstracto derivado y orientado a disquisiciones teóricas, sino un modo estenográfico de designar una postura de investigación que pone al modo de pensamiento genético en el corazón del análisis social.

Both the physiological and the pathological morphogenetic processes that we can meet in embryogenesis, neogenesis and degenerative dysgenesis present common features: they are ruled by three different kinds of mechanisms, one related to cell migration, the second to cell differentiation and the third to cell proliferation. We deal here with an application to the cambial growth which essentially involves the third type of mechanism.Woody plants produce secondary tissue (secondary xylem and phloem) from a meristematic tissue called vascular cambium, responsible for (...) the radial growth of a tree. This paper focuses on the formation of secondary xylem, considered in two dimensions in a cross-section framework. A new discrete modelling approach is used, based on the cellular scale, in order to attain a more accurate understanding of how the elementary microscopic behaviour of each cell takes part in the macroscopic morphogenesis. The mathematical model essentially uses an occurrence method simulating the main features of radial growth with simple geometric rules, such as Thom's division rule (Thom,1972)to account for the cell proliferation. The study applies to concrete instances in which the changes made in the geometrical cellular patterns of the vascular cambium clearly affect the shape of the tree, as in Pinus radiata (D. Don.).

Reasonning in naive set theory (with unlimited comprehension), we derive a paradox (a formal contradiction) which can be seen as a variant of the Burali-Forti paradox.

Using as case studies the initiatives developed by two museum curators, the Belgian bibliographer Paul Otlet (1868–1944) and the Austrian social scientist Otto Neurath (1882–1945), and their subsequent collaboration with an extended network of scientists, philanthropists, artists, and social activists, this article provides a portrait of the general movement toward the creation of a new form of museum: the “museum of the future,” as Neurath labeled it. This museum would be able to enlighten the people by showing the nature of (...) modern industrial civilization. The promoters of the “museum of the future” intended to reform museum practices by organizing exhibitions of social facts, but also by integrating several dimensions – architecture, commerce, entertainment, pedagogy, and science and technology – to create a holistic frame to address their audience. However, the effortlessly circulating museum Neurath and Otlet envisioned stood in sharp contrast to the many, often immaterial, boundaries they encountered in their attempt to implement their vision. Ever-growing nationalism, the professionalization of social science, and the increasing commercialization of scientific vulgarization are some of the factors that help explain their failure.

We introduce a notion of syntactical truth predicate (s.t.p.) for the second order arithmetic PA 2 . An s.t.p. is a set T of closed formulas such that: (i) T(t = u) if and only if the closed first order terms t and u are convertible, i.e., have the same value in the standard interpretation (ii) T(A → B) if and only if (T(A) $\Longrightarrow$ T(B)) (iii) T(∀ x A) if and only if (T(A[x ← t]) for any closed first (...) order term t) (iv) T(∀ X A) if and only if (T(A[X ←▵]) for any closed set definition $\triangle = \{x \mid D(x)\}$ ). S.t.p.'s can be seen as a counterpart to Tarski's notion of (model-theoretical) validity and have main model properties. In particular, their existence is equivalent to the existence of an ω-model of PA 2 , this fact being provable in PA 2 with arithmetical comprehension only. (shrink)

L’installation et le développement de la discipline universitaire « Sciences et techniques des activités physiques et sportives » ne peuvent être pleinement compris que si l’on voit qu’ils résultent de l’action conjointe de facteurs cognitifs et sociaux. La perspective sociohistorique montre que ce qui est arrivé récemment a d’abord été préparé par un long processus non linéaire et complexe. Mais il a encore fallu sur le court terme un dynamisme cognitif interne et des effets sociaux multiples, enchevêtrés, voulus et non (...) voulus, afin que s’établissent l’instutionnalisation irréversible de cette nouvelle discipline universitaire, son « académisation », puis son expansion « démographique ».The setting-up and development of the « sport sciences » as an academic discipline can only be fully grasped by acknowledging that it results from the combined action of both cognitive and social factors. Viewed in a social and historical light, what has recently taken place proves to have come at the end of a long, complex and winding process. But, in the short run, internal cognitive dynamics as well as multiple and intertwined social effects – whether intended or not – were also necessary for the non-reversible institutionalization of this new academic discipline, its establishment as part of the academia and eventually its « demographic » expansion.
