La presente investigación consiste en el análisis de la obra del escritor y filósofo Fabrice Hadjadj, desde la perspectiva de uno de los conceptos clave en ella: la «carne». La importancia de la carne para entender al hombre es una intuición desarrollada por Hadjadj en contraposición al espiritualismo dominante de la nueva era tecnológica. Nos encontramos en una era post-ideológica que se caracteriza por el dominio de lo tecnológico. Además, otra de las grandes novedades de nuestro tiempo es la conciencia (...) mayoritaria de la posibilidad de extinción de la especie humana. La crisis actual es profunda, antropológica: se trata de la pérdida de sentido de lo «humano». Esta crisis se ve agravada por una visión cada vez más desencarnada del hombre o espiritualista, lo que supone una ruptura antropológica que es promovida por el impacto de las tecnologías en nuestra lógica. Según Hadjadj, es este espiritualismo lo que contribuye más profundamente a diluir lo humano y acelerar la deriva poshumana de los nuevos tiempos. Nuestro trabajo, además de despejar cuál es el sentido de la carne para Hadjadj, así como el porqué de su particular relevancia para la nueva era, muestra algunas de las principales consecuencias de esa ruptura antropológica que promueve el uso de las tecnologías. La finalidad de esta investigación es mostrar cómo una visión antropológica centrada en la carne como la que propone Hadjadj, constituye una poderosa alternativa (si no la única) para resistir a la tentativa de que el espiritualismo tecnológico acabe devorando lo humano.

Este artículo se centra en la música en el entorno Fluxus entendida como creación artística de aproximación a la conquista del espacio y de superación de los límites sonoros, en aras a potenciar su expresión a través de la acción del intérprete y la utilización de artefactos. El resultado de todo ello fue un repertorio de imágenes de una gran potencia connotativa en el panorama artístico de los años sesenta.

BackgroundThe Catalan Institute of Health is the largest health services public provider in Catalonia. “CIH Code of Ethics Virtual Forum”, was created within the Intranet of the CIH to facilitate participation among their employees. The current study aims to: a) Analyse the CIH workers’ assessment of their own, their colleagues’ and the organization’s observance of ethical values; b) Identify the opinions, attitudes, experiences and practices related to the ethical values from the discourse of the workers that contributed voluntarily to the (...) CEVF.MethodsMixed methods study with convergent parallel design:1.Cross sectional study by means of a self-administered, ad hoc, anonymous questionnaire to assess the observance of the ethical values of the CIH according to the participants. A total of 712 workers responded to the questionnaire. A descriptive, bivariate analysis of the results was carried out. 2.Qualitative study to determine the meaning for the workers of the ethical values put forward by the organization. Their individual opinions and experiences were explored by means of a thematic contents analysis of 225 comments posted in the CEVF. The study was conducted between May and December 2008.ResultsThe average score for observance of the CE by the respondents themselves was high, between 3.5-4/5 for the observance by their colleagues and close to 3/5 for the CIH management. These results do not change when we compare by gender, age group and professional discipline. The comments on the values are information-rich, they mirror the ethical environment of the institution and show various ethical dilemmas and suggestions.ConclusionsResults show that it is feasible for a publicly funded health care organization to develop a CE with the participation of employees and the support of the management. Results underscore the relevance of this strategy for the implementation, improvement and update of the CE as a responsibility shared by all workers. Practices consistent with ethical values are rewarded by social approval, enhance employee’s confidence and coherence in decision-making and improve public engagement and institutional policies.

The great object of Augustus in celebrating Ludi saeculares in 17 b.c. was to encourage the belief in himself and the consequent active loyalty to himself, as the restorer of the pax deorum,—the good relation between the divine and human inhabitants of Rome. So far he had tried to attain this end by the ancient usual and proper means, i.e. by carrying out the various regulations of the ius diuinum, so many of which had long been neglected. But in that (...) year he determined to undertake a special celebration, with the design of more effectually stamping the impression already made on the minds of the people; and it so happens that we have more detailed knowledge of this celebration than of any other Roman rite of any period. This is fortunate, for it stands on the margin between an old and a new régime, like the Aeneid of Virgil, who had died two years earlier: that great religious poem was just becoming known, and there is an allusion to it in the hymn of which I am going to speak. The Ludi were the outward or ritualistic expression of the idea immortalized by the poet, that a regeneration is at hand of Rome and Italy, in religion, morals, agriculture, government: old things are now to be put away, a new and glorious era is to open. Henceforward the Roman was to look ahead of him in hope and confidence, trusting in Augustus, the Aeneas of the actual State. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 127.4 (2006) 607-611MuseSearchJournalsThis JournalContents[Access article in PDF]Reviewed byPaul Allen Miller University of South Carolina e-mail: [email protected] Habinek. The World of Roman Song: From Ritualized Speech to Social Order. Baltimore: Johns Hopkins University Press, 2005. x + 329 pp. Cloth, $52.It has become increasingly evident that the texts we study from ancient Rome are embedded objects, implicated in a rich field of symbolic systems and corporeal (...) practices. The image of the poem as an isolated aesthetic object has become untenable as the field has become dominated by concepts of intertextuality, performativity, social construction, and self-fashioning. The text in books like Tony Corbeill's Controlling Laughter (Princeton 1996) is less an object than an action. Thomas Habinek's The World of Roman Song represents an attempt to make good on the promise of these developments by rethinking the entirety of Roman literature as an embedded social process of "song," of marked speech, that stands at the origins of the Roman social order. Ritual hymns, funereal laudations, convivial play, and comedic performances become so many moments in the constitution of what it means to be Roman, even as conflicts between center and periphery, masculine and feminine, vir and cinaedus are both played out and resisted in the various genres that constitute the world of ritualized speech and its formal derivatives.Any such sweeping endeavor brings with it both a necessary boldness—asking us to rethink the history of Roman culture from a new perspective—and the danger of reductiveness. For the most part, these are dangers that Habinek manages skillfully to skirt through a combination of fine-grained philological analysis and a sophisticated, but never overbearing, theoretical apparatus. The World of Roman Song features close readings of the usage of words such as cano, carmen, dico, ludus, convivia, and sodalis, from their earliest attestations through their appearance in later imperial literature. It also deploys an intellectual armature that draws upon contemporary anthropology, Frankfurt-school Marxism, object-relations psychoanalysis, and the theories of Bourdieu, Bakhtin, and Bataille. Yet, as we shall see, the very methodology that makes this sweeping [End Page 607] and important survey possible—the examination not of texts but of lemmata to trace the memes of Roman self-constitution through formalized language—leads to certain unavoidable distortions. Complex textual systems become reduced to exemplary moments of embeddedness. This reduction is an enabling gesture that like any mode of analysis, however, ultimately produces its own limit.For this reader, the heart of the book is to be found in chapter 4, "Song and Play." Here Habinek traces the relation between three primary sets of terms: dico, dictum, and implicitly dictator, meaning to make an authoritative statement; cano, canto, and carmen, meaning to perform a song (carmen) of one's own (cano), or to repeat that of another (canto), so as to establish a relation between the singer and the constituted social, and ultimately cosmic, whole, via ritualized speech; and ludo, ludus, and lusus, referring to scripted or formalized movements of the body. Thus a poetic ludus, such as that described in Catullus 50 between the poet and Licinius Calvus, would refer not so much to the acts of song (carmina) to which the game of composition gave rise as to the formalized interchange and embodied practice of writing capping verses in different meters in a convivial setting. The previous chapter, "Song and Speech," had established the difference between loquor and dico, with the former referring to unmarked speech and the latter to the making of statements that the speaker asserts as authoritative and hence true. It is thus possible for the terms cano and dico to overlap and those of ludo and cano as well. Nevertheless, the ultimate dream of aristocratic Roman manhood (and, as any number of feminists would point out, of patriarchy as a whole) is for carmen—the ritualized speech that constitutes the community as a living unity—to assume the status of dictum, authoritative speech freed from the...

The shadowy Roman god Sēmō and the plural group Sēmōnēs have long been associated with sēmen ‘seed.’ But the evidence that Sēmō or the Sēmōnēs have anything to do with seeds is lacking. The Sēmōnēs first appear in the Carmen Arvale: here they constitute Mars's retinue. The Sabellic evidence also puts Semo firmly in the Martial sphere. The form Semo appears, in addition, as part of the Semo Sancus Dius Fidius complex. These divinities are connected with the sanctity of (...) treaties and oaths. In “Dumézilian” terms Semo is a god of the first and second function, but not a god of the third function, precisely the opposite of what the standard etymology predicts. New evidence from Oscan allows us to reject conclusively the connection between sēmen and Sēmō. In an inscription from Pietrabbondante the god's name is spelled seemuneí and this spelling with ee is not the expected one. If the Oscan form were a derivative of the root seen in sēmen, the spelling would have to have been †síímuneí. The spelling ee shows that the Oscan form, and its Latin cognate, must have a different origin. The only plausible source is *seγVmōn-. A form that matches reconstructed *seγVmōn- exactly is Gaulish Segomoni and Ogham Irish SEGAMANAS. The Gaulish god is identified with Mars. The Celtic and Italic forms continue a Proto-Italo-Celtic *seĝhomōn- ‘strong one,’ ‘strongman,’ which is a derivative of a noun *seĝhom ‘strength.’ The root *seĝh- had the original meaning ‘hold firmly’ and this developed to ‘be strong,’ ‘conquer’ in Indo-Iranian and Western Indo-European. The god *seĝhomōn- is the sole example of a divine name that perhaps can be considered a unique and innovative feature of the ancient Proto-Italo-Celtic speech community. (shrink)

One day towards the end of the eighth century the scribe of cod. Paris. Lat. 7530, a miscellany to which we owe the carmen de figuris , began to copy out for us, on the 28th leaf of the MS, the Thyestes of Varius. He transcribed the title and the prefatory note, which run thus: INCIPIT THVESTA VARII. Lucius Varius cognomento Rufus Thyesten tragoediam magna cura absolutam post Actiacam uictoriam Augusti ludis eius in scaena edidit, pro qua fabula sestertium (...) deciens accepit. Then he changed his mind: he proceeded with a list of the notae employed by Probus and Aristarchus, and the masterpiece of Roman tragedy has rejoined its author in the shades. (shrink)

An important contemporary version of Boltzmannian statistical mechanics explains the approach to equilibrium in terms of typicality. The problem with this approach is that it comes in different versions, which are, however, not recognized as such and not clearly distinguished. This article identifies three different versions of typicality‐based explanations of thermodynamic‐like behavior and evaluates their respective successes. The conclusion is that the first two are unsuccessful because they fail to take the system's dynamics into account. The third, however, is promising. (...) I give a precise formulation of the proposal and present an argument in support of its central contention. †To contact the author, please write to: Department of Philosophy, Logic, and Scientific Method, London School of Economics, Houghton Street, London WC2A 2AE, England; e‐mail: [email protected].

The United Kingdom Climate Impacts Programme’s UKCP09 project makes high-resolution projections of the climate out to 2100 by post-processing the outputs of a large-scale global climate model. The aim of this paper is to describe and analyse the methodology used and then urge some caution. Given the acknowledged systematic, shared errors of all current climate models, treating model outputs as decision-relevant projections can be significantly misleading. In extrapolatory situations, such as projections of future climate change, there is little reason to (...) expect that post-processing of model outputs can correct for the consequences of such errors. This casts doubt on our ability, today, to make trustworthy probabilistic projections at high resolution out to the end of the century. (shrink)

On an influential account, chaos is explained in terms of random behaviour; and random behaviour in turn is explained in terms of having positive Kolmogorov-Sinai entropy (KSE). Though intuitively plausible, the association of the KSE with random behaviour needs justification since the definition of the KSE does not make reference to any notion that is connected to randomness. I provide this justification for the case of Hamiltonian systems by proving that the KSE is equivalent to a generalized version of Shannon's (...) communication-theoretic entropy under certain plausible assumptions. I then discuss consequences of this equivalence for randomness in chaotic dynamical systems.

John Fischer has recently argued that the value of acting freely is the value of self-expression. Drawing on David Velleman’s earlier work, Fischer holds that the value of a life is a narrative value and free will is valuable insofar as it allows us to shape the narrative structure of our lives. This account rests on Fischer’s distinction between regulative control and guidance control. While we lack the former kind of control, on Fischer’s view, the latter is all that is (...) needed for self-expression. I first develop Fischer’s narrative account, focusing on his reliance on temporal loops as giving us control over the value of our lives. Second, I argue that the narrative account grants us greater power over the past than Fischer would allow: since narrative allows not only for changes in how we feel about episodes in our past but what those episodes in fact were, it allows for a kind of retroactive self-constitution. Finally, I suggest that this modification of the narrative view opens the possibility of a conception of freedom far stronger than guidance control. It does not give us the libertarian control over whether to choose A or B in the present, but it does provide a measure of control over the sort of person an agent has been, and thus whether she is the sort of person who will choose A or B in the future.

In two recent papers Barry Loewer (2001, 2004) has suggested to interpret probabilities in statistical mechanics as Humean chances in David Lewis’ (1994) sense. I first give a precise formulation of this proposal, then raise two fundamental objections, and finally conclude that these can be overcome only at the price of interpreting these probabilities epistemically.

The last decade and a half has seen an ardent development of self-organised criticality, a new approach to complex systems, which has become important in many domains of natural as well as social science, such as geology, biology, astronomy, and economics, to mention just a few. This has led many to adopt a generalist stance towards SOC, which is now repeatedly claimed to be a universal theory of complex behaviour. The aim of this paper is twofold. First, I provide a (...) brief and non-technical introduction to SOC. Second, I critically discuss the various bold claims that have been made in connection with it. Throughout, I will adopt a rather sober attitude and argue that some people have been too readily carried away by fancy contentions. My overall conclusion will be that none of these bold claims can be maintained. Nevertheless, stripped of exaggerated expectations and daring assertions, many SOC models are interesting vehicles for promising scientific research.Author Keywords: Self-organised criticality; Scaling law; Models; Formal analogy.

Sustainable investment, which integrates social, environmental and ethical issues, has grown from a niche market of individual ethical investors to embrace institutional investors resulting in £764 billion in assets under management in the UK alone [Eurosif, 2008: ‘European SRI Study 2008’ ]. Explaining this growth is complex, involving shifts in personal and collective values, reactions to corporate scandals, scientific and media pronouncements about climate change, Government initiatives, responses from financial markets and the influence of SI innovators in The City of (...) London. The article examines the influence of human agency through interviews with 14 SI champions who have variously been responsible for launching SI funds and changing investment processes and organisational structures in order to enhance SI. Interviewees were asked about their motivations and persuasive strategies, the obstacles they faced and how they overcame them as well as broader implications of SI for financial markets. The following key categories inform the results and the discussion: Values; Conservatism, Antipathy and Incredulity; Optimism and Sympathy from Insiders; The Social and Political Context; The Business Case; Organisational Constraints; Inappropriate forms of Remuneration; Short-termism; The Nature of Capitalism. Three discourses were also identified. The first is the necessity to make a business case for SI; the second is the benefits that SI can bring to the quest of overcoming short-termism; the third is a belief that for SI to have a significant influence, greater government intervention is required.

In lieu of an abstract, here is a brief excerpt of the content:Big Women:Mark Adamo's Lysistrata, or the Nude Goddess Between Monteverdi and Musical ComedyRalph HexterWe live in an age when opera companies across America are regularly presenting new operas, and some of them are even making hesitant first steps into repertory status, though it is too soon to tell how long- or short-lived their performance history will be. Opera itself began—Peri's Dafne (1597) is commonly regarded as the starting point—as (...) an attempt to recreate Greek tragedy on the stage, and for at least its first two hundred years, plots drawing on classical material, if not always classical literary texts, were staples. Nineteenth-century opera composers were relatively less inclined to turn to the classics for plots and characters, but the twentieth century witnessed renewed activity in classically based operas, from Strauss' Elektra (1909) and Stravinsky's Oedipus Rex (1927) to Hans Werner Henze's Venus und Adonis (1997) and Randolph Peters' The Golden Ass (1999), to name but a few significant examples. Mark Adamo's Lysistrata, or the Nude Goddess, which premiered in Houston in 2005, is among the first operas in our new century to continue the tradition.Accompanied by a trio of distinguished distaff classicists, I attended the 2006 revival of Lysistrata, or the Nude Goddess at the New York City Opera. Some months later, as word of the outing—any resemblance to this or any other Aristophanic comedy is purely accidental—trickled out, AJP's editor asked me to write this "Brief Mention." The reader will infer, then, that I neither watched nor listened with the idea of writing such a notice. What follows are reflections based partially on recollection of my immediate impressions (especially of the music) but also on subsequent study of the published libretto,1 Adamo's earlier and quite popular Little Women (1998), and stray remarks of the composer in published or online [End Page 119] interviews. In no sense is it a review of the particular April 2nd matinee performance that I saw. Of that let me say that my impression was almost uniformly positive. The principals, who have very demanding parts (and not only vocally), were strong; several were reprising roles they had taken in the Houston world premiere.Adamo states on the title page of the libretto that the opera is "[f]reely adapted from the play by Aristophanes," and this is both true and to the good. Before I turn to the adaptation itself, it might be worth observing that within the reception history of ancient stageworks in opera, the tradition of classical comedies turned into operas is relatively slight. I put it that way because, of course, one might well argue that New Comedy in its Roman form is the ultimate source of all opera buffa. I say nothing new when I place Figaro directly in the line of servi callidi.2Greek Old Comedy (i.e., given the state of preservation, Aristophanes) has only infrequently provided fodder for opera. One of the most interesting cases is Walter Braunfels' setting of Aristophanes Birds—Die Vögel—premiered in 1920. Braunfels (1882–1954) was fired from his teaching post by the Nazis in 1933—he was half Jewish—and his works were banished from the repertory. Die Vögel, his most successful stagework, has been recently revived, and a recording is available in Decca's "Entartete ["degenerate"] Musik" series. One must also recall the famous Frogs performed in the pool of Yale's Payne Whitney Gymnasium in 1941, since, a generation later, in 1975, the piece was revived, provided with music and lyrics by Stephen Sondheim and, like so many other shows, transferred from New Haven (if not the Shubert) to Broadway.3Aristophanes is more at home, I would argue, in American musical comedy than in opera, at least opera as it has come to be received by modern audiences treated almost without exception to post-Gluckian opera, with major houses, until recently, shunning the more interesting hybrids. (Think even of Carmen and how long it took for it to lose the recitatives by Guiraud that replaced the original opéra comique spoken dialogue.) To modern spectators or readers, Aristophanes, with...

Strictly speaking, Aristotle did not formulate a theory of the emotions, but we find indications of one in several of his treatise. Many studies about his conception of the emotions lose sight of the fact that the Aristotelian analysis of the passions or emotions in every theoretical context respond..

The time honoured philosophical issue of how to resolve the mind/body problem has taken a more scientific turn of late. Instead of discussing issues of the soul and emotion and person and their reduction to a physical form, we now ask ourselves how well-understood cognitive and social concepts fit into the growing and changing field of neuropsychology. One of the many projects that have come out of this new scientific endeavour is Zaidel’s (2005) inquiry into the neuropsychological bases of art.

Ennius began his Annals with a prayer to the Muses: Musae quae pedibus magnum pulsatis Olympum. In this he differs from his predecessors. Livius in his Odusia had substituted Camena for Homer's Μοσα, and the ‘novem Iovis concordes sorores’ to whom Naevius addresses himself in the Carmen Belli Punici also bore the name of Camenae, as we may infer with some confidence from Naevius' epitaph: ‘Immortales mortales si foret fas flere Flerent divae Camenae Naevium poetam.’ The mysterious Carmen (...) Priami likewise speaks of the Camenae: ‘Veteres Casmenas cascam rem volo profari.’ For general reasons it seems unlikely that before Ennius' time the Romans were altogether unfamiliar with the name of Musae. Evidence, however, to show that they knew it is not available. Nevertheless, even if the name Musae was known, in invoking their patronage for his poem Ennius is making a departure from the habits of earlier poetry, of which he is both conscious and proud. In the beginning of the seventh book he speaks with scorn of his predecessor Naevius: ‘scripsere alii rem Versibus quos olim Fauni vatesque canebant Cum neque Musarum scopulos…’ Now the reign of the Muses begins, and the grave virus of the Saturnian line is driven out by the munditiae of the hexameter.

Using Leventhal’s (Social exchange: Advances in theory and research, Plenum Press, New York, 1980 ) rules of procedural justice as well as deontic justice (Folger in Research in social issues in management, Information Age, Greenwich, CT, 2001 ), we examine how personal value for diversity moderates the negative relationship between perceived discrimination against minorities (i.e., racial minorities and females) at work and the perceived procedural justice of minorities’ treatment by the organization. Through a field survey of 190 employees, we found (...) that observers high in personal value for diversity have stronger negative reactions to the mistreatment of women and racial minorities than observers low in personal value for diversity. These findings support and extend the deontic justice perspective because those who personally value diversity had the strongest negative reactions toward the discriminatory treatment of minorities.

The formalism of quantum mechanics provides us with the probabilities for certain events to occur—this much is uncontroversial. But how are we to understand these probabilities? The essays in this special issue approach this question from different angles. The first three contributions take as their point of departure the philosophy of probability and discuss what the two main outlooks—objective and subjective interpretations of probability—have to offer in the context of quantum mechanics. The following five papers explore the question of how (...) probabilities in particular interpretations of quantum mechanics—modal interpretations, relative state interpretations, Bohmian mechanics, and GRW theory—can be interpreted. The last three essays address specific issues: non-standard probability and algebraic quantum field theory, quantum propensities, and the relation between decoherence and the interpretation of probability.

The roles models play in science have long been recognised and sparked rich and varied philosophical debates. In recent years attention has also been paid to the computational techniques used in the sciences, and the question arose what the implications were of the use of computer simulations for our understanding of scientific modelling, and science more generally. This was the subject of the conference “Models and Simulations”, which took place at the IHPST in Paris in June 2006. Selected papers of (...) that conference appeared in a special issue of this journal (Synthese 169(3) (2009)). After the conference there was a general feeling that there still was much ground to cover, and so we decided to organize a follow up a year later. “Models and Simulations 2” took place in October 2007 at the Tilburg Center for Logic and Philosophy of Science (TiLPS) in the Netherlands. The conference was made possible due to generous financial support from IHPST (Paris, CNRS), Universitat de Barcelona, TiLPS (Tilburg Center for Logic and Philosophy of Science) and the Evert Willem Beth Foundation. The papers in this special issue were presented at the conference and selected after a double-blind review process. We would like to thank the authors and referees of the papers for their work, and Vincent Hendricks and John Symons for their support of the project of another special issue on models and simulations.

Zusammenfassung Dem deutschen Fußball scheint es geradezu mühelos zu gelingen, Spielerinnen und Spieler mit Migrationshintergrund zu integrieren, was sich deutlich in der Zahl betreffender Spielerinnen und Spieler in den Auswahlmannschaften des Deutschen Fußball Bundes zeigt. Die Mannschaften des Deutschen Handball Bundes dagegen rekrutieren sich bislang ausschließlich aus rein deutschstämmigen Spielerinnen und Spielern. Beim Handballsport scheint es sich hierzulande bislang um etwas ausgesprochen „Deutsches“ zu handeln, mithin um eine Sportart, die fast 20 % der Bevölkerung kaum erreicht und dabei offenkundig sogar (...) die größte Migrantengruppe, nämlich diejenige mit muslimischem Hintergrund, so gut wie vollständig ausschließt. Der Aufsatz steckt sich das Ziel, all jene Mechanismen der Exklusion von Migranten im Handball zu identifizieren und in einem theoretischen Modell zusammenzufassen, die in Deutschland zur Unter- bzw. Nichtrepräsentanz von Spielerinnen und Spielern mit unterschiedlichem Migrationshintergrund im Handballsport beitragen. Aufbauend darauf werden Leitfragen für eine empirische Untersuchung der Exklusionsmechanismen abgeleitet. (shrink)

We present a proof of the equivalence between two deductive systems for constructive necessity, namely an axiomatic characterisation inspired by Hakli and Negri's system of derivations from assumptions for modal logic , a Hilbert-style formalism designed to ensure the validity of the deduction theorem, and the judgmental reconstruction given by Pfenning and Davies by means of a natural deduction approach that makes a distinction between valid and true formulae, constructively. Both systems and the proof of their equivalence are formally verified (...) using the state-of-the-art proof assistant Coq. The proof approach taken throughout the paper unveils the use of some alternative proof methods that allow for a smooth transition from the high-level mathematical proofs to their mechanised counterparts.

As concerns heighten over links between biomass production and land grabs in the global south, attention is turning to understanding the role of governance of biofuels systems, whereby decision-making and conduct are not solely determined through government regulations but increasingly shaped by non-state actors, including multi-stakeholder initiatives. Launched in 2005, Bonsucro is the principal MSI that focuses on sustainability standards for sugar and sugarcane ethanol production. Bonsucro claims that because it is free from government interference and draws on scientific metrics, (...) their standards transcend localized, political–economic contexts. In this paper, we illustrate how the local context shapes the prospects for Bonsucro sustainably certified biofuel production in relation to land and water grabs. To accomplish this, our case focuses on Colombia, which has used a range of national policy mandates to establish itself as one of the larger producers of agrofuels in Latin America. We draw on interviews with stakeholders in the sugar and ethanol industries, paired with an examination of Bonsucro principles on land rights and water use, to illustrate how the sugar industry is framing their participation in Bonsucro, and the effects of the increasing intensification of sugarcane for ethanol production on land and water access for communities. We find that within the context of Colombia, efforts such as Bonsucro provide a veil of legitimacy and authority to a system that is premised on deeply entrenched historical patterns of inequitable land ownership patterns and access to natural resources.

Philosophe polonais et disciple d'Edmund Husserl, Ingarden envisage la relation a l'oeuvre d'art comme une experience menee dans un echange reciproque et continu avec l'objet. Il defend ainsi une esthetique qui n'est ni purement subjectiviste en ce qu'elle n'est en rien reductible aux sentiments emotionnels d'un sujet, ni purement objectiviste en ce que les determinations reelles et materielles de l'oeuvre donnee exigent la participation intentionnelle du spectateur pour s'accomplir en manifestation intuitive concrete. Objet intentionnel par excellence, l'oeuvre d'art se tient (...) entre monde reel et monde spirituel, entre realite et jeu imaginaire. Elle se donne au spectateur comme une invitation a deployer son activite intentionnelle et, ce faisant, a participer a la vie de l'oeuvre a travers l'histoire de ses receptions. Les textes reunis ici offrent un large panorama des preoccupations esthetiques d'Ingarden. Ils presentent les principaux resultats de ses recherches theoriques concernant la nature des vecus et des objets esthetiques, ainsi que des applications concretes des analyses ontologiques menees sur differents types d'oeuvres d'art (litterature, peinture, architecture et film). L'ensemble des analyses ontologiques et phenomenologiques y est egalement toujours adosse a la question des valeurs, et de l'evaluation artistique ainsi qu'a la recherche d'un fondement objectif des valeurs.
