Skin, paper, tiles: a cross-cultural history of Kadiwéu art

This article focuses on the global traffic in images relating to Kadiwéu culture in South America, analyzing the extent to which they are entangled in the group’s continuing sense of presence. It begins with Kadiwéu designs as they appeared in the sketchbook of the artist-explorer Guido Boggiani in the late nineteenth century. It then explores the mapping of Kadiwéu territory and the practices and protocols informing a politics of land rights, cultural property and economic survival, looking in particular at the commissioning of Kadiwéu designs for a housing estate and an associated exhibition in Berlin early in the twentieth-first century. By developing a cross-cultural history of Kadiwéu art that considers the transnational networks across different times and spaces, including the case of a transcultural history of copyright, the article seeks to contribute to the ongoing re-thinking of the colonial archive and its afterlife

Reply to ten comments on a paper published in the last issue of this journal. The discussion follows along six main lines: History museums, identity, ideology and the category of nation; the need of material collections and their modalities: patrimonial, operational, virtual; theater versus laboratory; visitors and their ambiguities; Public History: the museum and the academy.Resposta aos comentários de dez especialistas que contribuíram no debate de texto publicado no último número desta revista.

Structural phase transitions of multiferroic Bi0.7La0.3FeO3

Bi0.7La0.3FeO3 has received special attention in the last years, since it exhibits ferroelectricity and ferromagnetism at room temperature. Issues including understanding of the mechanisms related to ferroelectric and magnetic phase transitions and the correlation of structure, magnetism, and ferroelectricity are still under debate. Though, first PND data obtained in ISIS allow for an acceptable discussion of its structure, key information is still missing. The aim of this proposal is to carry out a high-resolution neutron diffraction experiment in HRPD across the phase transition, to ascertain crucial details of its structure, closing in this way the first obtained HRPD data. From this study, we envisage to fully determining symmetry and lattice distortions towards phase transitions, and highlight the main underlying mechanisms, especially the role of spin-lattice couplin
