Industrialized agriculture currently substitutes many of the ecological functions of soil micro-organisms, macroinvertebrates, wild plants, and vertebrate animals with high cost inputs of pesticides and fertilizers. Enhanced biological diversity potentially offers agricultural producers a means of reducing the cost of their production. Conservation of biodiversity in agricultural landscapes may be greatly enhanced by the adoption of certain crop management practices, such as reduced pesticide usage or measures to prevent soil erosion. Still, the vast monocultures comprising the crop area in many (...) Canadian agricultural landscapes are often of limited conservation value, thus the inclusion of appropriate wildlife habitat in and around arable lands is a fundamental prerequisite for the integration of wild species within agricultural landscapes. This review of current literature considers the potential for non-crop areas within agricultural landscapes to be reservoirs of agronomically beneficial organisms including plants, invertebrates, and vertebrate species. Non-crop habitats adjacent to crop land have been identified as significant for the maintenance of plant species diversity, for the conservation of beneficial pollinating and predatory insects, and as essential habitat for birds. A key component for enhancement of biodiversity is the reintroduction of landscape heterogeneity by (1) protection and enhancement of key non-crop areas, (2) smaller fields and farms, and (3) a greater mixture of crops, through rotation, intercropping and regional diversification. The benefits of increased biodiversity within arable lands are reviewed for various species groups. In the Canadian context, any serious attempt to derive significant agronomic benefit from increased biodiversity will require considerable changes in the agricultural programs and policies which shape mainstream industrialized agriculture. The problems of crop depredation by vertebrate species, weed and insect competition, which still represent significant impediments to the creation and proper management of wildlife habitat, are also discussed.

La theorie physique? Ce titre, qui fut au debut de notre siecle celui d'un ouvrage controverse, suggere bien une question, celle de savoir si en matiere de science la theorie doit se qualifier en fonction d'un domaine plus particulier d'application. L'auteur, Pierre Duhem, n'aurait pas hesite, semble-t-il, a repondre par l'affirmative en ce qui concerne le vaste champ de la recherche que l'on peut signifier sous le nom de physique. Son ouvrage est en fait construit comme une preparation rigoureuse (...) a une telle reponse et bien que les annees aient modifie considerablement le contexte du champ sus-dit, les analyses proposees ont ete jugees suggestives par de nombreux epistemologues d'aujourd'hui.

Carnap's ideal of explication has become a key concept in analytic philosophy and the basis of a method of analysis which may be considered as an alternative to various forms of naturalism, including Quine's conception of a naturalized epistemology. More recently, new light has been shed on this aspect of the classical Carnap-Quine debate by contemporary philosophers. Whereas Michael Friedman articulated a notion of relativized a priori which owes much to Carnap's internal/external distinction, André Carus attempted to restate Carnap's ideal (...) of explication in a way that bridges the gap between conceptual engineering and naturalism. On the other hand, Mark Wilson argued that concepts develop in unpredictable ways and cannot be planned in the way classical analytic philosophy has assumed from Frege and Russell onwards. This book consists of a series of defences as well as critiques of Carnap's programme, setting it in its historical context, discussing specific cases of explications, and enriching the on-going debate on conceptual engineering and naturalism in analytic philosophy.Carnap's ideal of explication has become a key concept in analytic philosophy and the basis of a method of analysis which may be considered as an alternative to various forms of naturalism, including Quine's conception of a naturalized epistemology.

In multicellular organisms, cells are frequently programmed to die. This makes good sense: cells that fail to, or are no longer playing important roles are eliminated. From the cell’s perspective, this also makes sense, since somatic cells in multicellular organisms require the cooperation of clonal relatives. In unicellular organisms, however, programmed cell death poses a difficult and unresolved evolutionary problem. The empirical evidence for PCD in diverse microbial taxa has spurred debates about what precisely PCD means in the case of (...) unicellular organisms. In this article, we survey the concepts of PCD in the literature and the selective pressures associated with its evolution. We show that definitions of PCD have been almost entirely mechanistic and fail to separate questions concerning what PCD fundamentally is from questions about the kinds of mechanisms that realize PCD. We conclude that an evolutionary definition is best able to distinguish PCD from closely related phenomena. Specifically, we define “true” PCD as an adaptation for death triggered by abiotic or biotic environmental stresses. True PCD is thus not only an evolutionary product but must also have been a target of selection. Apparent PCD resulting from pleiotropy, genetic drift, or trade-offs is not true PCD. We call this “ersatz PCD.”. (shrink)

This introduction specifies the context in which the texts that make up the dossier were written, presents them and outlines their respective main axes. In a second, more distant phase, it opens up three critical questions, linked to what Joas proposes and aiming to continue the discussion on what is at stake at the social, political and religious levels. It welcomes the aim of a 'self-reflection of social and cultural sciences on their biological bases and normative contents' in relation to (...) historically determined social and political problems. It underlines the anthropological substratum explored by the Joassian approach, which aims to highlight what is at stake between the individual and social bodies, the singular creativities of human action, and the social structures and dynamics. It is under this horizon that the three questions that mark a gap with Joas' work emerge. The first one focuses on the games between body and overcoming, and what is mobilised there, where collective organisation that is not reducible to politics alone and to what would be proper to it, takes shape. The second returns to the question of rite, to evoke its importance at the heart of our worldly activities, in a secular and non-religious mode. The third part takes up the strictly religious question, questioning how Joas deals with the modern differentiation of social spheres, as well as the absence, in his work, of a critical analysis of religions in their traditions, with all the pathologies that may run through them.

Non-cognitive gadgets are fancy tools shaped to meet specific, local needs. Cecilia Heyes defines cognitive gadgets as dedicated psychological mechanisms created through social interactions and culturally, not genetically, inherited by humans. She has boldly proposed that many human cognitive mechanisms are gadgets. If true, these claims would have far-reaching implications for our scientific understanding of human social cognition. Here we assess Heyes’s cognitive gadget approach as it applies to mindreading. We do not think that the evidence supports Heyes’s thought-provoking thesis (...) that human children are taught to read minds the way they are taught to read words. We highlight a potential circularity lurking behind this analogy, and we explain why we are unpersuaded by Heyes’s anti-mentalistic proposal for handling data inconsistent with the gadget view, which others take to be evidence for mindreading in human infancy. We conclude that while human minds may well be filled with gadgets, mindreading is unlikely to be one of them. (shrink)

L'épistémologie s'intéresse à la connaissance scientifique aux points de vue logique et méthodologique. Soit elle cherche les fondements du savoir qui précèdent la science elle-même, soit elle pose ses problèmes à l'intérieur de la science. Or, depuis que la science mathématique de la nature tend à une forme de mathématique pure, cette distinction classique n'est plus vraiment pertinente. Au-delà des questions épistémologiques habituelles, cet ouvrage propose une lecture critique de la science moderne, où la notion de "fondement" est élargie aux (...) "premiers gestes". Lorsque Galilée a formulé la loi de la chute des corps sous une forme mathématique, il a considéré que les corps du monde physique réel se déplacent dans un espace vide, qui est un milieu idéal. Il a ainsi violé l'interdit posé par Aristote sur le mouvement dans le vide, et depuis lors la question du rapport de la pensée à l'intuition a été soulevée dans le cadre d'une interrogation inédite sur la Nature. La science de la nature a poursuivi son chemin vers sa mathématisation à outrance, et les grandes étapes de ce chemin que sont les théories de la relativité et de la mécanique quantique ont fini par faire resurgir les fantômes de l'intuition qui sont comme des piqûres de rappel du sens de ce qui a été ouvert pour commencer. Il fallait donc poser la question qui fut celle de Husserl : avant de tomber dans le vide, les corps ne sont-ils pas tombés énigmatiquement du vide pour susciter les premiers gestes du savoir? La loi de Galilée ainsi questionnée devient l'emblème d'une interrogation philosophique inédite. Le vide d'où surgissent les phénomènes naturels renvoie en amont de la nature, vers le monde de la vie sur lequel la science n'a pas de prise bien qu'elle en émane. Qu'est-ce qui s'effectue dans ce monde? En essayant d'approfondir cette question, la phénoménologie retrouve dans la science cette dimension intuitive de l'expérience que la science met en question. Dans une métaphysique de la nature tirée de la philosophie transcendantale, Kant l'avait déjà esquissée sous la forme d'une équivoque de l'intuition. Equivoque aussi riche de sens que porteuse d'une énigme à l'horizon de ces premiers gestes du savoir qu'aucun savoir constitué ne peut épuiser. (shrink)

Le mal est une notion qui s’étend au moins sur trois champs disciplinaires : la théologie, la philosophie et l’art. Il connaît un même traitement dans chacun de ces trois champs, motivé par des systèmes différents : le mal n’est jamais pris comme objet causa sui mais toujours considéré dans sa relativité à un objet premier dont il contribue à définir la limite. Nous proposons un rapide tour d’horizon de cette situation afin d’ouvrir les pistes de réflexion d’une intelligibilité du (...) comportement de cette notion dans l’histoire des idées. Nous suivons un ouvrage de Paul Ricœur et saisissons certains textes clefs de l’histoire de la pensée au travers de l’objet problématique qu’est le mal, évoquant notamment les travaux plus récits avec la méthode herméneutique proposée par Hans Blumenberg afin de percevoir la figure du diable comme l’objet pratique d’une telle observation dans le fil de l’histoire des idées.

We study the role of meeting numbers in pcf theory. In particular, Shelah's Strong Hypothesis is shown to be equivalent to the assertion that for any singular cardinal σ of cofinality ω, there is a size collection Q of countable subsets of σ with the property that for any infinite subset a of σ, there is a member of Q meeting a in an infinite set.

This paper assesses the scope and limits of a widely influential model of goal-ascription by human infants: the shared-intentionality model. It derives much of its appeal from its ability to integrate behavioral evidence from developmental psychology with cognitive neuroscientific evidence about the role of mirror neuron activity in non-human primates. The central question raised by this model is whether sharing a goal with an agent is necessary and sufficient for ascribing it to that agent. I argue that advocates of the (...) shared-intentionality model underestimate both the distinction between the target and the goal of a goal-directed action and the gap between sharing and ascribing a goal.

Abstract This paper compares Heidegger's conception of time with more prevalent physical and broadly psychological analyses of time. The ?vulgar? notion of time, as Heidegger understands it, is based on the assumption that time, regardless of whether it is identified with tense or not, is something that is essentially measurable by clocks. Heidegger maintains that the vulgar notion of time is a distortion of his own preferred conception of temporality. I show how temporality may be understood as the non?sequential tensed (...) structure underlying tensed discourse. I argue against any straightforward reduction of this tensed structure and the direction of time to physical occurrences. Nevertheless I argue that temporality can be distinguished from purely psychological analyses of temporal experience and from traditional conceptions of time as tensed experience. The selectiveness of demonstrative discourse provides the basis for Heidegger's critique and reconstruction of time understood as tensed discourse about things. Heidegger's scepticism about the interpretation of time as a sequence of nows that underlies the dominant interpretation of tense is due to his appropriation of the relativity of simultaneity from special relativity. But his interpretation of physical theory leads him to the thesis that time is pre?supposed but not completely analysed in physical theory. The meta?language of physical theory makes covert use of temporal notions, for entities can themselves only be understood in covertly temporal ways. I show how this claim may be understood and defended in the light of current physical theory. Heidegger's analysis gives us some basis for thinking that his own notion of temporality is built into an understanding of temporal experience. But I argue that Heidegger fails to make the case that physical time is ontologically dependent on human existence. (shrink)

Attributing the creation of new features to categorization requirements implies that the exemplars displayed are correctly assigned to their category. This constraint limits the scope of Schyns et al.'s proposal to supervised learning. We present data suggesting that this constraint is unwarranted and we argue that feature creation is better thought of as a byproduct of the attentional, on-line processing of incoming information.

This paper draws from critical data studies and related fields to investigate police officer-involved homicide data for Los Angeles County. We frame police officer-involved homicide data as a rhetorical tool that can reify certain assumptions about the world and extend regimes of power. We highlight the possibility that this type of sensitive civic data can be investigated and employed within local communities through creative practice. Community involvement with data can create a countervailing force to powerful dominant narratives and supplement activist (...) projects that hold local officials accountable for their actions. Our analysis examines four Los Angeles County police officer-involved homicide data sets. First, we provide accounts of the semantics, granularity, scale and transparency of this local data. Then, we describe a “counter data action,” an event that invited members of the community to identify the limits and challenges present in police officer-involved homicide data and to propose new methods for deriving meaning from these indicators and statistics.

Versé autant dans les arts libéraux que dans les arts mécaniques, Spinoza fut aussi tailleur de verre à Amsterdam, sans doute acteur de théâtre, probablement dessinateur. Il fréquenta la boutique d'antiquaire de Franciscus Van den Enden et fut proche de la société des arts Nil volentibus arduum ; il habitait non loin de Rembrandt et Potter et appréciait la compagnie de peintres et de décorateurs. Élaborée au coeur du siècle d'or de la peinture hollandaise, cette philosophie a souvent inspiré les (...) artistes.

L'altérité est l'un des phénomènes les plus étudiés et l'un des concepts les plus utilisés au cours des trente dernières années, mais c'est aussi une notion des plus polysémiques et des plus controversées, jusque dans les usages idéologiques qu'on peut en faire aujourd'hui. Ce livre interroge les bases philosophiques, le contexte sociohistorique et la portée éthique et esthétique de ce phénomène ou de cette notion à la lumière de ses différentes valeurs. L'autre est à la fois l'étranger, exclu ou minorisé, (...) pour les études culturelles, l'un des pôles de la construction identitaire pour certaines théories du sujet, l'expression même de la Loi et du Symbolique pour d'autres, la figure emblématique de la responsabilité pour une certaine pensée éthique, le fondement de toute relation intersubjective et de tout dialogisme ou, plus radicalement encore, la manifestation de la nature essentiellement hétérogène de l'existence. Chaque fois, ce qui est en jeu concerne nos manières de vivre-ensemble et nos façons de faire et de créer. Les auteurs réunis dans cet ouvrage analysent les "politiques de l'altérité" que notre histoire impose ou propose comme choix de société et " les poétiques de l'autre" que les différentes pratiques artistiques, ancrées dans la mémoire et l'imaginaire collectifs, déploient comme possible ou comme alternative face à notre situation historique.

In mass democracies, voting—in elections or referendums—is the main way in which most citizens can publicly express their political preferences. And yet this means of expression is sometimes perceived by them as highly frustrating, partly because it does not allow for much expression. Dominant voting methods lead to a reduction of options, pressure citizens to vote tactically at the cost of expressing their genuine preferences, and fail to convey what they really think about different candidates, parties, or options. Yet citizens (...) do not merely have a right to vote; they have a more fundamental right to political expression from which one can derive a right to a voting method that offers the most opportunities for expression among those satisfying other important requirements. The aim of this article is therefore to add this consideration about the importance of political expression to debates about voting methods that have mainly been conducted from the perspective of social choice theory. To illustrate what is at stake, it introduces evaluative voting methods (allowing voters to grade all of the candidates, parties, or options) as a promising way of honoring the right to political expression without jeopardizing other important properties of voting methods.

Dans le traité De la divination dans le sommeil, Aristote entend réfuter la thèse d’une origine divine des rêves qui semblent annoncer les événements futurs. Pour cela, il ne se contente pas de soutenir une thèse différente. Il dénonce également la faiblesse épistémologique de la pratique divinatoire, en proposant un modèle scientifique alternatif : une méthode de classification des rêves et de division par épuisement, qui exclut les rêves inspirés. Cette méthode conduit à souligner le caractère irréductible des faits de (...) hasard et à admettre le caractère inexplicable d’un grand nombre de rêves « véridiques ». La notion de coïncidence ( sumptôma ) joue sur ce point un rôle essentiel. Ce rôle est à la fois descriptif et critique : il permet de définir la classe des rêves dont la dimension véridique est absolument fortuite, et il dénonce l’illusion commune qui les relie à des événements réels. De ce point de vue, le chapitre 1 du De divinatione apporte une contribution, modeste mais spécifique, à la théorie des modalités physiques. (shrink)

At the heart of the controversy, the hijab or headscarf has stirred passions that have led to heated social tensions.
