Nonlinear responses of ecosystem carbon fluxes to precipitation change in a semiarid grassland
Published 2025-02-01“…In this study, we conducted a three-year field experiment in a semiarid grassland, with six precipitation treatments (precipitation decreased by 70%, 50%, and 30% [P–70%, P–50%, and P–30%], natural precipitation [P+0%], and precipitation increased by 30% and 50% [P+30% and P+50%]) to examine how variations in precipitation influence ecosystem C fluxes, specifically focusing on gross ecosystem productivity (GEP), ecosystem respiration (ER), and net ecosystem CO2 exchange (NEE). We found that both decreased and increased precipitation significantly altered the GEP (from –26% to 14%), but only decreased precipitation significantly reduced the ER and NEE (from 1% to 31%), relative to their values during natural precipitation. …”

Ecstasy’s Alembic: H.D.’s Poetics of Magic and Psychoanalysis in World War Two
Published 2014-01-01“…Celui-ci s’éclaire notamment si l’on explore les liens entre la cure psychanalytique de H.D. avec Sigmund Freud dans la Vienne de 1933-1934 et son engagement spirituel avec le médium Arthur Bhaduri dans le Londres de l’après-Blitz. De ce terreau est née une double figure visionnaire mêlant une Mère-déesse et un Saint-Esprit féminisé qui serait au principe de la force spirituelle de la poésie, du pouvoir des mots en tant que tels, celui d’apporter apaisement et résurrection dans un monde en ruines.…”

Divergence and Convergence in the New Zealand Bicultural Model
Published 2007-05-01“…Lorsque les gouvernements néo-zélandais se sont orientés vers une politique de réconciliation au début des années 1980, ils cherchèrent à se confronter au problème de la dualité d’une nation née en 1840 de l’alliance de deux peuples : les Maoris et les Britanniques.Peut-être le résultat le plus spectaculaire de ce processus fut-il l’adoption graduelle d’un modèle biculturel qui accordait aux maoris le statut officiel de peuple natif tangata whenua, ceci en vue de restaurer l’unité et l’harmonie tout en promouvant la différence culturelle. …”
