Penser l’hégémonie dans le monde contemporain
No full textIs There a Possible Dialogue Between Hegemony and Cosmopolitanism? Interview with Frédéric Ramel -- What do the two concepts of hegemony and cosmopolitanism imply? Are they opposed or is there a possible dialogue between them? In a recently published chapter (“Competition for Hegemony ” in the edited volume Cosmopolitanism in Hard Times), Professor of political science at Sciences Po CERI Frédéric Ramel questions these concepts and explores their scope. The following is an interview with the author. Interview by Miriam Perier, CERI
Caught in the nuclear trap(s)? The responsibility and findings of independent scholarship
No full textBenoit Pelopidas is the author of Repenser les choix nucléaires. La séduction de l'impossible, published last January by Presses de Sciences Po and currently being translated into English. Through systematic research conducted over more than a decade, at the crossroads of nuclear history and international relations, the author addresses essential notions such as proliferation, the security dilemma, vulnerability, and chance to name but a few. He answers our questions about his work, his approach, and his firm stance on the independence of research. This interview was conducted with Benoît Pélopidas on the occasion of the fifth anniversary of the Nuclear Knowledges programme
Spatial and temporal variability of hard-bottom macrofauna in a disturbed coastal lagoon (Sacca di Goro, Po River Delta, Northwestern Adriatic Sea)
No full textThe sessile and mobile macrobenthos on artificial hard bottoms was studied in 12 stations of the Sacca di Goro lagoon, a brackish, highly stressed water basin in the delta of the river Po, open to the Northwestern Adriatic Sea. Three sampling surveys were carried out in June and September 2000 and June 2001 in order to make three types of temporal comparisons: (i) on a seasonal scale, before and after a summer dystrophic event; (ii) on an annual basis, before and after the works of excavation of a canal through the outer sand bank; (iii) on a multiannual scale, comparing the data with those of a survey carried out in 1988. The biocoenoses did not show large fluctuations after a moderately severe summer dystrophic crisis, while the digging of the canal caused clear changes in the macrobenthos community structure after one year. The long-term comparison showed a shift in the community patterns after a decade
Reconstructing Last Glacial Maximum and Younger Dryas paleolandscapes through subsurface paleosol stratigraphy: An example from the Po coastal plain, Italy
No full textPaleosols are commonly used to reconstruct ancient landscapes and past environmental conditions. Through identification and subsurface mapping of two pedogenically modified surfaces formed at the onset of the Last Glacial Maximum (LGM) and during the Younger Dryas (YD) cold event, respectively, and based on their lateral correlation with coeval channel-belt sand bodies, we assessed the geomorphic processes affecting the Po coastal plain during the Late Pleistocene (30â11.5 cal ky BP). The 3D-reconstruction of the LGM and YD paleosurfaces provides insight into the paleolandscapes that developed in the Po alluvial plain at the transitions between warm and cold climate periods. The LGM paleosol records a stratigraphic hiatus of approximately 5 kyr (29â24 cal ky BP), whereas the development of the YD paleosol was associated with a climatic episode of significantly shorter duration. Both paleosols, dissected by Apennine rivers flowing from the south, dip towards the north-east, where they are replaced by fluvial channel belts fed by the Po River. The LGM channel-belt sand body reflects the protracted lateral migration of the Po River at the onset of the glacial maximum. It is wider (> 24 km) and thicker (~ 15 m) of the fluvial sand body formed during the YD. The northern margin of LGM Po channel-belt deposits was not encountered in the study area. In contrast, a spatially restricted paleosol, identified in the north at the same elevation as the southern plateau, may represent local expression of the Alpine interfluve during the YD event. This study highlights how 3D-mapping of regionally extensive, weakly developed paleosols can be used to assess the geomorphic response of an alluvial system to rapid climate change
La Chose nue : parité, restitution, spectre
No full text“Disappearance” is at the heart of the studies and novels of Hadrien Laroche, who reexamines for us “the thing” in the work of Martin Heidegger, Jacques Derrida, and Meyer Shapiro. We are familiar with the discussion around Van Gogh’s shoes, a still life lively enough to give rise to some very keen, contradictory interpretations. In introducing the Marquis de Sade into the game, the author allows us to broach the delicate question of the human being’s treatment as a thing by both artists and philosophers.La disparition est au cœur des études et des romans de Hadrien Laroche qui revient pour nous sur « la chose » chez Heidegger, Derrida et Schapiro. Nous connaissons la discussion autour des Souliers de Van Gogh, nature morte suffisamment vivante pour susciter des interprétations contradictoires d’une grande vivacité. En introduisant Sade dans le jeu, l’auteur nous permet d’aborder la question délicate du traitement de l’humain comme chose par l’artiste et le philosophe
L’utilizzo delle acque superficiali nelle pompe di calore: un caso di studio
No full textSi discute il progetto di un impianto a pompa di calore al servizio di un nuovo complesso residenziale. La pompa di calore sfrutta come sorgente di calore l’acqua del Po di Volano, che scorre adiacente al terreno. Essendo disponibili i valori orari misurati di temperatura dell’acqua, sono stati ricavati i bin mensili sulla base dei quali sono state effettuate le valutazioni energetiche secondo UNI TS 11300-4, confrontate poi con quanto ricavato per valori medi mensili di temperatura. I risultati ottenuti in termini di riduzione dei consumi energetici e massimizzazione dello fruttamento di fonti rinnovabili mettono chiaramente in luce l’elevato potenziale dello sfruttamento delle risorse idriche come il Po di Volano, come sorgente per pompe di calore. Per questo motivo si ritiene che abbia senso continuare nell’approfondimento di tale tematica anche in aree in cui storicamente tali impianti non hanno avuto diffusione nonostante le acque superficiali siano abbondanti, alla ricerca di soluzioni dalle elevate prestazioni energetiche, compatibilmente con elevate prestazioni ambientali
À propos du populisme
No full textcontribution à un site webOn the basis of a reading of seven books devoted to populism, the author discusses the various ways in which philosophers, political scientists and historians have approached the phenomenon. He addresses the thorny question of how populism is to be defined and the relationship between populists and democracy. He also examines how social scientists position themselves with regard to populism and argues for respecting value neutrality when addressing the topic.À partir d’une lecture de sept ouvrages consacrés au populisme, l’auteur discute différentes approches de ceux-ci proposées par des philosophes, des politistes et des historiens. Il s’intéresse à la question épineuse de la notion de populisme et aux rapports qui s’établissent entre les populistes et la démocratie. Il examine le positionnement qu’adoptent les chercheurs en sciences sociales par rapport au populisme et plaide en faveur du respect de la neutralité axiologique
La comunità dei Peracaridi come indicatore di eterogeneità spaziale in ambienti lagunari adriatici.
No full textThe community of Peracarids from hard bottoms was studied in 2004 in two lagoons at different climatic and hydromorphologic regimes: the Sacca di Goro in the Po river delta, of about 26 km2 and depth between a few centimetres and over 2 metres, and the Lesina lagoon, in the Gargano promontory, of about 53 km2, almost uniform depth of about 80 cm and two narrow lagoon mouths. The differences between the two basins, outlined by the multivariate analysis, were mainly due to
the different abundance of the 30 identified species rather than to their mere presence. Peculiar elements were not lacking, and were particularly related to seawater exchange at Goro, and to a moderate desalination, that involved almost the entire basin, at Lesina. This condition resulted in a strong biocenotic homogeneity, with dominance of the isopod Sphaeroma serratum and presence of other eurihaline species such as Gammarus sp. pl., Echinogammarus pungens and Melita palmata. At Goro, instead, a more marked spatial heterogeneity could be noticed, related to an active harbour and to the noteworthy freshwater supply from the Po river, that also generated some localized estuarine communities. Globally, the lagoon was characterized by Corophium sp. pl. and Melita palmata. The comparison with data from previous years in the Sacca di Goro allowed to investigate the response of the Peracarid community to variations of the seawater exchange
