Ever since it was discovered in hydra, regeneration has remained a stimulating question for developmental biologists. Cellular approaches have revealed that, within the first few hours of apical or basal hydra regeneration, differentiation and determination of nerve cells are the primary cellular events detectable. The head and foot activators (HA, FA), neuropeptides that are released upon injury, are signaling molecules involved in these processes. In conditions where it induces cellular differentiation or determination, HA behaves as an agonist of the cyclic (...) AMP (cAMP) pathway involving the modulation of CREB nuclear transcription factor activity. This cascade would be required for proper regeneration, regardless of whether the polarity involved is apical or basal. Modulations of the protein kinase C pathway, which have been shown to affect apical or basal positional values, might signal to bring about this polarity; however, endogenous ligands responsible for this modulation are as yet unknown.

Le travail avec les familles ayant une histoire en lien avec la migration nécessite une réflexion et une écoute adaptées. Dans ce contexte a été pensé un dispositif thérapeutique au sein d’un centre médico-psychopédagogique pour accueillir et prendre en compte l’origine culturelle ainsi que la situation transculturelle de ces familles. Cet article relate l’expérience clinique d’une mère et de son enfant autour de contes issus de la tradition orale du Maghreb dans le cadre d’un atelier rassemblant des dyades mères-enfants. Le (...) dispositif a pu restaurer le lien symbolique et dyadique, activer une autorisation à apprendre. La remobilisation des représentations culturelles au travers du conte a joué un rôle essentiel dans la renarcissisation à un niveau individuel pour une (re)construction identitaire. (shrink)

After the UN Guiding Principles on Business and Human Rights were adopted in 2011, an international treaty has been being negotiated since 2014. The two instruments reveal similarities and also conflicts regarding the adequate organization of the global economy based on human rights. The focus in this article will be on the processes leading to these instruments, because they themselves mirror different understandings of governance in the field of business and human rights as well as the struggle over the power (...) of definition and legitimacy. The UNGPs were developed on the basis of global multi-stakeholder consultations, underlining legitimacy through broad inclusion. There are varying judgements as to the success of this approach. The process towards the treaty follows the traditional path of negotiations at UN level. These negotiations reveal a struggle for recognition of the legitimacy of the process itself. Both procedures have shortcomings with regard to legitimacy and show the need for a revision concerning the inclusion of stakeholders. The complementarity of a soft and hard law instrument may enhance the creation of a level playing field in the global economy, thereby strengthening human rights. (shrink)

Currently, affect and emotions are a widely discussed political topic. At least since the early 1990s, different disciplines—from the social sciences and humanities to science and technoscience—have increasingly engaged in studying and conceptualizing affect, emotion, feeling, and sensation, evoking yet another turn that is frequently framed as the “affective turn.” Within queer feminist affect theory, two positions have emerged: following Eve Kosofsky Sedgwick's well-known critique, there are either more “paranoid” or more “reparative” approaches toward affect. Whereas the latter emphasize the (...) potentialities of affect, the former argue that one should question the mere idea of affect as liberation and promise. Here, I suggest moving beyond a critique or celebration of affect by embracing the political ambivalence of affect. For this queer feminist theorizing of affective politics, I adapt Jacques Rancière's theory of the political and particularly his understanding of emancipation. Rancière takes emancipation into account without, however, uncritically endorsing or celebrating a politics of liberation. I draw on his famous idea of the “distribution of the sensible” and reframe it as the “distribution of emotions,” by which I develop a multilayered approach toward a nonidentitarian, nondichotomous, and emancipatory queer feminist theory of affective politics.

This article adds to earlier research revealing that the American news media did not discharge their responsibility as a watchdog press in the post-9/11 years by failing to scrutinize extreme and unlawful government policies and actions, most of all the decision to invade Iraq based on false information about Saddam Hussein’s alleged weapons of mass destruction arsenal. The content analyses presented here demonstrate that leading US news organizations, both television and print, did not expressly refer to human rights violations when (...) they reported on the torturing of foreign detainees during “enhanced interrogations” in US-run prison facilities abroad and the killing of civilians, including children, in US drone strikes overseas and outside theaters of war. Moreover, by framing torture and the “collateral damage” caused by drone-launched missile attacks episodically rather than in the context of human rights, the news media failed to alert the American public to the grave humanitarian violations in the so-called war on terrorism during the George W. Bush and Barack Obama administrations. (shrink)

The physics of condensed matter, in contrast to quantum physics or cosmology, is not traditionally associated with deep philosophical questions. However, as science - largely thanks to more powerful computers - becomes capable of analysing and modelling ever more complex many-body systems, basic questions of philosophical relevance arise. Questions about the emergence of structure, the nature of cooperative behaviour, the implications of the second law, the quantum-classical transition and many other issues. This book is a collection of essays by leading (...) physicists and philosophers. Each investigates one or more of these issues, making use of examples from modern condensed matter research. Physicists and philosophers alike will find surprising and stimulating ideas in these pages. (shrink)

Brigitte Bourgeois and Philippe Jockey Gold and Marble: the Gilded Hellenistic Sculptures of Delos p. 331-349 The investigation we are conducting on the polychromy of the Hellenistic sculptures of Delos has enabled us to add to the corpus of gilded marble works and to refine the typology. A visual examination of the sculptures through a video-microscope, combined with an analysis of the remains isolated by this means under X-fluorescence, has revealed the existence of three large types of gold leaf (...) gilding on marble at Delos in around 100 BC: totally gilded statues, works on which the gilding forms only an added colouring to the general polychromy, and works that we propose to call "chrysochromes", which present a singularity not hitherto recognised of a very bright polychromy on the clothed parts associated with gold on the nude parts. Among the number of important results of this enquiry may be counted the revelation of the overall gilding on the Delian copy in the National Museum at Athens of the Polyclitus Diadumenus, carved and gilded in imitation of a gilt bronze or even a gold statue. Such a use of gold leaf gilding on the Delos marbles calls in any case for a reconsideration of the question of the reception in antiquity of such works, as well as of such a success of gold at Delos and no doubt elsewhere in the Greek world in the same period.

Grace de Laguna was a philosopher working in the first part of the twentieth century on analytic and speculative philosophy, as well as on the psychology and philosophy of language, especially the social function of language. Joel Katzav’s lead essay focuses mainly on the former part of her work, while my commentary focuses mostly on the latter. Katzav shows how her work played a role in the development of analytic philosophy, I try to show how her work played a role (...) in the development of pragmatic linguistics, whose development overlapped with some aspects of analytic philosophy. I situate it in the context of an emerging ‘pragmatic Weltanschauung’ that was embraced by many working in linguistics, philology, philosophy, psychology, anthropology and what would later be called linguistic pragmatics.

En envisageant la communication dans une perspective anthropologique, Dell Hathaway Hymes a introduit le langage en acte - verbal et non verbal - au coeur de l'analyse sociolinguistique. L'étude du langage qu'il a développée va évoluer d'une « ethnographie de la parole » vers une ethnographie de la communication, ouvrant la voie à une pragmatique et à une anthropologie communicationnelle.Considering the communication from an anthropological perspective, Dell Hathaway Hymes has introduced the language act - verbal and nonverbal - in the (...) heart of sociolinguistic analysis.

One of the first Swiss performance artists, Manon has fashioned a career for herself out of the identities of others. Whether exploring the limits of gender or the beauty of decay, Manon—through her personas, installations, and performance pieces—continually foregrounds the instability of place and self. Her most recent project, She Was Once MISS RIMINI, is one of her most brutal and touching. Here, she literally depicts imagined futures for an aging beauty queen. Each exquisite image in this pictorial essay teases (...) out the possible paths Miss Rimini—an alter-ego for Manon who “happened” upon a beauty pageant in the early 1970s and walked away with the crown—could have taken. A small-town diva? A hypersensitive viola player? Perhaps even a psychiatric patient? She Was Once MISS RIMINI is a trenchant meditation on the art, or artifice, of growing older. Costume, lipstick, lighting, attitude—all aspects of self-presentation are in concert here with quiet critiques of social and economic systems that limit the options of older women. Accompanied by an enlightening introduction by art theorist Brigitte Ulmer, She Was Once MISS RIMINI is the first and only documentation of Miss Rimini and one of the first books in English on Manon.

Die Arbeit untersucht die auflagenstärkste und international bekannteste deutsche Zeitung des 18. Jahrhunderts, die "Staats- und Gelehrte Zeitung des Hamburgischen unpartheyischen Correspondenten", mit dem Ziel, ihre Rolle als Instrument der Aufklärung zu analysieren. Basis der Studie sind als regelmäßige Stichprobe die Jahrgänge 1731, 1741,..., 1781. Auf einen ersten Teil, der sich mit der Unternehmensgeschichte der Zeitung, ihrer Konzeption sowie den Prinzipien der 'unpartheylichen' Nachrichtenmeldung in der politischen Berichterstattung und der 'unpartheylichen' Kritik in den Rezensionen des "Hamburgischen Correspondenten" beschäftigt, folgt ein (...) zweiter inhaltsanalytischer Teil. Dort liegt das Interesse nicht primär auf der Rezeption bestimmter Ereignisse oder Schriften, die von der Forschung als 'Meilensteine' der Aufklärungsbewegung ausgemacht wurden. Vielmehr werden in fünf zentralen Themenbereichen (Wissenschaftsverständnis, Literaturkritik, Rezeption staatswissenschaftlicher und ökonomischer Theorieelemente, bürgerliches Selbstverständnis, Frauenbild) für die Aufklärung typische Argumentationsmuster und Werte nachgewiesen, die den Zeitungslesern durch wiederholte Lektüre so vertraut werden mußten, daß sie ihre Weltanschauung im Sinne der Aufklärung beeinflussen konnten.

This book, first published in 2000, offers translations of the initial critical reactions to Kant's philosophy. Also included is a selection of writings by Kant's contemporaries who took on the task of defending the critical philosophy against early attacks. The first aim of this collection is to show in detail how Kant was understood and misunderstood by his contemporaries. The second aim is to reveal the sorts of arguments that Kant and his first disciples mounted in their defense of the (...) theoretical philosophy. The third aim of the book is to contribute to an understanding of the development of Kant's critical philosophy after its initial formulation in the Critique of Pure Reason, and in particular why Kant made the changes he did in the second edition of the work in 1787. This collection, which includes a glossary of key terms and biographical sketches of the critics on both sides of the debate, is a major addition to Kant scholarship and should be seen as a companion volume to the Cambridge Edition of the Works of Immanuel Kant.

In recent years, feelings such as melancholia, paranoia, despair and political depression have been deemed distinctive political moods, also within critical theories. This, the author argues, is the affective landscape for understanding and situating new materialist endeavours. As much as new materialist approaches have been praised and even celebrated lately, they have also provoked highly controversial reactions and evoked questions, such as: Why a new materialism, why at this historical moment? And what is so attractive about this material turn? In (...) this article, the author argues that new materialist approaches seek to oppose the contemporary affective condition of political depression, despair and hopelessness by desiring and mobilizing to achieve a different political future, one that ultimately relates to care and commonality as well as to modes and modalities of political agency. However, while new materialist approaches doubtlessly provide engaged and powerful inventions and interventions within contemporary struggles for agency, the author also demonstrates the risk of depoliticization inherent in this longing for something different, which can ultimately even compromise opening up possibilities for agency. This article, thus, aims to discuss new materialist concerns within the context of contemporary political and theoretical landscapes in order to better decipher the new materialist signals of our times, but also to critically push further the possibilities for political agency within feminist theory, at times even against all odds.

Welche Erkenntnisse bietet Michel Foucaults Ansatz der Gouvernementalität für eine politische Theorie, die Geschlecht als zentrale Kategorie setzt? In diesem Band werden Grundbegriffe aus Foucaults Spätwerk aus feministischer Sicht beleuchtet, z.B. Gouvernementalität, Macht, Staat, Subjekt, Sicherheit, Wissen und Kritik. Diese Re-Lektüre möchte zum einen Foucaults Ansatz geschlechtertheoretisch weiterentwickeln und vertiefen, zum anderen Anstöße für eine politische Theoretisierung von Geschlecht geben.

Entrepreneurs who start a business to serve both self-interests and collective interests by addressing unmet social and environmental needs are usually referred to as sustainable entrepreneurs. Compared with regular entrepreneurs, we argue that sustainable entrepreneurs face specific challenges when establishing their businesses owing to the discrepancy between the creation and appropriation of private value and social value. We hypothesize that when starting a business, sustainable entrepreneurs feel more hampered by perceived barriers, such as the institutional environment and have a different (...) risk attitude and perception than regular entrepreneurs. We use two waves of the Flash Eurobarometer survey on entrepreneurship, which contains information on start-up motivations, start-up barriers, and risk perceptions of approximately 3000 business owners across 33 countries. We find that sustainable entrepreneurs indeed perceive more institutional barriers in terms of a lack of financial, administrative, and informational support at business start-up than regular entrepreneurs. Further, no significant differences between sustainable and regular entrepreneurs are found in terms of their risk attitudes or perceived financial risks. However, sustainable entrepreneurs are more likely to fear personal failure than regular entrepreneurs, which is explained by their varied and complex stakeholder relations. These insights may serve as an important signal for both governments and private capital providers in enhancing the institutional climate. (shrink)

This paper deals with some structural properties of the sequent calculus and describes strong symmetries between cut-free derivations and derivations, which do not make use of identity axioms. Both of them are discussed from a semantic and syntactic point of view. Identity axioms and cuts are closely related to the treatment of negation in the sequent calculus, so the results of this article explain some nice symmetries of negation.

Rapprocher Facebook du Kula mélanésien, un système archaïque d’échanges intertribaux décrit par Marcel Mauss, permet de souligner la capacité de la plateforme phare du Web 2.0 à répondre à des besoins socioculturels anthropologiquement attestés. Tous deux obéissent à une contrainte implicite de réciprocité qui, au-delà du contenu matériel des échanges, possède une fonction symbolique : les interactions mises en œuvre et la recherche de partenaires traduisent une quête de prestige, de mana selon le fameux terme chinook. Le Kula et les (...) murs de Facebook offrent une immense vitrine où chacun valorise son mana et scrute celui d’autrui tout en cherchant de nouveaux partenaires. Mobiliser le Kula tel un modèle de Simmel – un schème d’intelligibilité – indique l’ancienneté de ces traits culturels : la combinaison des dimensions matérielle et symbolique dans les échanges entre pairs et, en l’absence d’instance régulatrice, le risque lié à l’emballement de ce processus inévitablement concurrentiel.Our comparison between Facebook and Melanesia’s Kula, an archaic system of inter-tribal exchanges described by Marcel Mauss, has highlighted the ability of the flagship Web 2.0 platform to respond to anthropologically verified socio-cultural needs. Both systems obey an implicit demand for reciprocity, which, over and above the actual content of exchanges, has a symbolic function: the interactions at play and the search for partners reflect a quest for prestige, or mana as it is famously known in Chinook. Kula and Facebook’s walls are a gigantic shop window where anyone can show off their mana and look at other people’s, while also seeking out other partners. The use of the Kula as described by Simmel – as a model of intelligibility – suggests the ancient roots of these cultural traits: the combination of material and symbolic dimensions in exchanges between peers and, if there is no regulating authority, the risk that this inevitably competitive process may run out of control.

Paris a connu au xixe siècle une héroïsation la haussant au rang d’une Babylone ou Babel moderne. Le mur des fermiers généraux, qui enserra Paris jusqu’en 1860, doubla pendant quelques années les fortifications de Thiers, achevées en 1844 et détruites dans les années 1920, contribuant à la perception de la ville comme cocon, puis joyau protégé par son écrin. À l’époque du « Grand Paris », la « reine des cités » balzacienne, aujourd’hui cernée par le boulevard périphérique, restera le (...) cœur incontestable de la capitale future : ne conserve-t-elle pas intactes l’harmonie urbaine et l’aura culturelle façonnées en son siècle d’or?Paris in the 19th century was the theatre of a trend in urban planning that sought to elevate the city to the heroic status of a modern Babylon or Babel. The city wall erected by the “ fermiers généraux” , which enclosed Paris until 1860, was reinforced for a time by the fortifications completed by Thiers in 1844 and pulled down in the 1920s, thus strengthening perceptions of the city as a cocoon, and later a jewel nestling within its protective casket. Balzac’s “queen of cities”, the Grand Paris now encircled by the ring road, was necessarily the heart of the future capital: had it not preserved the essence of the urban harmony and cultural aura that took shape during its golden era?

It is widely believed by historians of linguistics that the 19th-century was largely devoted to historical and comparative studies, with the main emphasis on the discovery of soundlaws. Syntax is typically portrayed as a mere sideline of these studies, while semantics is seldom even mentioned. If it comes into view at all, it is usually assumed to have been confined to diachronic lexical semantics and the construction of some (mostly ill-conceived) typologies of semantic change. This book aims to destroy some (...) of these prejudices and to show that in Europe semantics was an important, although controversial, area at that time. Synchronic mechanisms of semantic change were discovered and increasing attention was paid to the context of the sentence, to the speech situation and the users of the language. From being a semantics of transformations', a child of the biological-geological paradigm of historical linguistics with its close links to etymology and lexicography, the field matured into a semantics of comprehension and communication, set within a general linguistics and closely related to the emerging fields of psychology and sociology.
