L’œuvre scientifique de Cyprien Ayer (1825-1884). Grammaire, Pédagogie et Dialectologie

Cyprien Ayer (1825–1888), figure marquante de la vie intellectuelle en Suisse au XIXe siècle, est l'auteur d’une vaste œuvre scientifique, journalistique et littéraire. Parmi ses travaux linguistiques les plus importants il faut mentionner sa Grammaire comparée de la langue française (1876; nombreuses rééditions), sa Phonologie de la langue française (1875), et son Introduction à l’étude des dialectes du pays (1878). Ce dernier texte, ouvrage pionnier dans le domaine des études francoprovençales, est réimprimé ici, précédé d'une introduction. Le présent recueil regroupe des contributions qui concernent l’œuvre linguistique et littéraire d’Ayer et ses rapports avec une autre figure-clef de la vie littéraire et intellectuelle en Suisse, Henri-Frédéric Amiel. Le recueil s’ouvre par une étude de la carrière d’Ayer et par une bibliographie de ses travaux scientifiques (grammaire, dialectologie, pédagogie, économie, géographie, statistique, politique, ethnographie).

Periodising globalisation: Mauritian integration into the sugar commodity chain (1825-2005)

Using the case study of Mauritius, and its integration into the international sugar commodity chain, this paper shows that the analysis of commodity chains can be fruitfully employed to respond to recent calls in the field of global/world history for a periodisation of globalisation. The entry of Mauritius into the British Empire brought about a particular kind of integration of the island into the capitalist world system. Central to this integration was the production of sugar under the West Indian Sugar Protocol, with this ultimately turning Mauritius from a free port into a plantation economy. This shaped the island's economic and political practice, and brought the formation of a range of institutions that sustained a high degree of inequality among Mauritians by finding ever newer ways of conciliating socio-economic mobility with exploitation. The paper discusses Mauritian history through the framework of bilateral and multilateral trading agreements that had a significant impact on the sugar industry, and kept the island economically dependent on this single crop. This only changed when the postcolonial state succeeded in diversifying the Mauritian economy during the 1970s and 1980s.

Climate-pollen relationships AD 1901-1996 in two small mires near the forest limit in the northern and central Swiss Alps

Climatic relationships were established in two 210Pb dated pollen sequences from small mires closely surrounded by forest just below actual forest limits (but about 300 m below potential climatic forest limits) in the northern Swiss Alps (suboceanic in climate; mainly with Picea) and the central Swiss Alps (subcontinental; mainly Pinus cembra and Larix) at annual or near-annual resolution from ad 1901 to 1996. Effects of vegetational succession were removed by splitting the time series into early and late periods and by linear detrending. Both pollen concentrations detrended by the depth-age model and modified percentages (in which counts of dominant pollen types are down-weighted) are correlated by simple linear regression with smoothed climatic parameters with one-and two-year timelags, including average monthly and April/September daylight air temperatures and with seasonal and annual precipitation sums. Results from detrended pollen concentrations suggest that peat accumulation is favoured in the northern-Alpine mire either by early snowmelt or by summer precipitation, but in the central-Alpine mire by increased precipitation and cooler summers, suggesting a position of the northern-Alpine mire near the upper altitudinal limit of peat formation, but of the central-Alpine mire near the lower limit. Results from modified pollen percentages indicate that pollen pro duction by plants growing near their upper altitudinal limit is limited by insufficient warmth in summer, and pollen production by plants growing near their lower altitudinal limit is limited by too-high temperatures. Only weakly significant pollen/climate relationships were found for Pinus cembra and Larix, probably because they experience little climatic stress growing 300 m below the potential climatic forest limit.
