Kopenawa Davi et Bruce Albert, La chute du ciel. Paroles d’un chaman yanomami

Depuis plus d’une dizaine d’années, le bruit courait dans les milieux de l’ethnologie que le tandem Kopenawa-Albert concoctait quelque chose de réellement exceptionnel. Certaines prémices avaient même déjà circulé (Albert 1993 ; Albert et Kopenawa 2003 ; Viveiros de Castro 2007). L’attente en aura valu la peine ! car voici un opus magnum sans équivalent dans l’anthropologie amazoniste. Nul doute que La chute du ciel… entrera dans le panthéon des grands textes de l’anthropologie et laissera un..

On Yanomami ceremonial dialogues: a political aesthetic of metaphorical agency

The Yanomami ceremonial dialogues (wayamou) are a ritualized form of verbal exchange aimed at inter-community conflict resolution. This paper is devoted to describing and analyzing these ceremonial dialogues, taking a closer look at a. the significance of their tropic nature; b. the role played by knowledge acquired in dreams; and c. the manner in which « naming » the forest socializes space, peopling it not only with communities, but also with resources and exchange possibilities. I shall demonstrate that this combination of features delineates a political aesthetics reminiscent of shamanic form and efficacy. Such proximity suggests lines of continuity between political and religious agency, helping to bridge the gap Amazonianist anthropology has carved between the analysis of intra-human politics and that between humans and non-humans.Los diálogos ceremoniales yanomami (wayamou) son una forma ritualizada de intercambio verbal orientada a la resolución de conflictos intercomunitarios. Este trabajo describe y analiza estos diálogos enfocándose en a. el significado de su carácter metafórico; b. el papel del conocimiento adquirido en sueños; y c. la forma en que el nombramiento del territorio socializa el espacio, poblándolo no solo de comunidades, sino también con sus recursos y posibilidades de intercambio. Trataré de demostrar que esta combinación de características nos coloca frente una estética política propia del chamanismo. Esta proximidad sugiere una continuidad entre tipos de agencia politíca y religiosa que puede ayudar a acortar la distancia que la antropología amazonista ha creado entre el análisis de la politica intra-humana y aquella que se lleva a cabo entre humanos y no-humanos.Les dialogues cérémoniaux yanomami (wayamou) sont une forme ritualisée d’échange verbal destinée à la résolution des conflits entre les communautés. Ce travail décrit et analyse ces dialogues en tenant compte : a. du sens de son caractère métaphorique ; b. du rôle des connaissances acquises lors des rêves ; et c. de la façon dont les dénominations données au territoire socialisent l’espace, tout en le peuplant non pas seulement de communautés mais aussi de ressources et de possibilités d’échanges. J’essaierai de montrer que cette combinaison de caractéristiques relève d’une esthétique politique propre au chamanisme. Cette proximité suggère une continuité entre différents types d’agence politique et religieuse. On pourra ainsi tenter de réduire les distances que l’anthropologie amazonienne a crée entre l’analyse de la politique entre les humains et celle qui se tient entre les humains et les non-humains

Articulação de sistemas médicos, diálogos cerimoniais e reuniões políticas: comentários sobre a antimestiçagem cosmopolítica para além do interétnico

Este texto visa ilustrar, por meio da etnografia de dois contextos, o primeiro do campo médico e o segundo do campo político, como os Yanomami da região do Alto Orinoco, na Venezuela, fazem combinações de práticas, objetos e ideias provenientes de seu mundo e o mundo dos brancos que mantém a diferença yanomami/brancos, apesar da sua mistura. Ofereço estes exemplos como um exercício de exploração em torno da ideia de antimestiçagem, como uma forma indígena de mistura sem fusão, isto é, de mistura que mantém explícita a origem diversa dos elementos de um composto

Records of the Crowned Eagle (Urubitinga coronata) in Moxos plains of Bolivia and observations about breeding behavior

The Crowned Eagle (Urubitinga coronata, Accipitridae) is a globally endangered raptor, endemic to central and southern South America. Little is known about this species in Bolivia and no nesting or prey data have been reported for the country until now. Between 2007 and 2011, we detected Crowned Eagles in four different locations in Moxos Savannahs of Beni Department, Bolivia. We observed an active nest of Crowned Eagle on 23 November 2007. The nest contained a nestling and it was placed on a living tree approximately 13 m in height and approximately 8 m above the ground. This nest was empty during September and October 2008, but contained another nestling on 15 November 2009. These represent the first breeding records for the Crowned Eagle in Bolivia. Prey remains at the nest observed included two nine-banded armadillos (Dasypus novemcinctus) and two six-banded armadillos (Euphractus sexcinctus). The minimum number of individual Crowned Eagles in the surveyed area was seven. Our observations of family groups, juveniles and two nestlings confirm the breeding of Crowned Eagles in the Moxos plains. Ectoparasites and uncontrolled burns may threaten the northwestern Bolivian population of the endangered Crowned Eagle.Fil: Berkunsky, Igor.

Passivation of Co/Al2O3 Catalyst by Atomic Layer Deposition to Reduce Deactivation in the Fischer-Tropsch Synthesis

The present work explores the technical feasibility of passivating a Co/γ-Al2O3catalyst byatomic layer deposition (ALD) to reduce deactivation rate during Fischer-Tropsch synthesis (FTS).Three samples of the reference catalyst were passivated using different numbers of ALD cycles (3, 6and 10). Characterization results revealed that a shell of the passivating agent (Al2O3) grew aroundcatalyst particles. This shell did not affect the properties of passivated samples below 10 cycles, inwhich catalyst reduction was hindered. Catalytic tests at 50% CO conversion evidenced that 3 and6 ALD cycles increased catalyst stability without significantly affecting the catalytic performance,whereas 10 cycles caused blockage of the active phase that led to a strong decrease of catalytic activity.Catalyst deactivation modelling and tests at 60% CO conversion served to conclude that 3 to 6 ALDcycles reduced Co/γ-Al2O3deactivation, so that the technical feasibility of this technique was provenin FTS
