Just as the exploration of geographic areas such as the Amazon is economically extractive, an extractive logic has informed ethnographic image production from its inception. Travelers collect valuable records to fulfill the interests and needs of metropolitan publics, as well as to furnish their museums, libraries, and archives—often leaving indigenous subjects diminished by the experience of contact. The cooperative Video in the Villages (VNA) attempts to invert this extractive pattern through the repatriation of archival images to indigenous communities and the introduction of video technology for indigenous use. Focusing on the group’s inaugural video and several recent works made in collaboration between indigenous and non-indigenous filmmakers, this chapter traces the group’s attempt to rework the contact imaginary and re-orient the ethnographic archive to serve indigenous needs.

This research analyses the discursive characteristic of social binding wheels discourse made in the framework of educational and communicative processes with different social and educational agents from different indigenous communities, from Pastaza (Ecuador). This discursive analysis consists of a qualitative inquiry of quantitative data regarding the potential of integrative community therapy (ICT) and the binding wheels. It aims to assess their impacts, their achievements, their difficulties through a methodology of mixed quanti-qualitative cutting. The obtained results demonstrate that binding wheels allow self-reflection and communicative exchange, promote resilience, and evidence community empowerment. Finally, we consider (that) this analysis may be of special interest to improve educational and communicative strategies in intercultural educational context of the Ecuadorian Amazon, allowing social value analysis and promoting personal development.

Abstract Even as progress has been made in extending access to safe water and sanitation under the Sustainable Development Goals (SDGs), substantial disparities in water, sanitation, and hygiene (WASH) services persist in high-income countries around the world. These gaps in service occur disproportionately among historically marginalized, rural, informal, and Indigenous communities. This paper synthesizes results from a side session convened at the 2020 University of North Carolina, Chapel Hill, Water and Health conference focused on knowledge gaps, challenges, and approaches to achieve SDG 6 among marginalized communities in high-income countries. We provide approaches and next steps to advance sustainable WASH services in communities that have often been overlooked.

Constitutional recognition of Indigenous Australians has been a longstanding national movement reflective of the international struggle of Indigenous communities within a colonial framework. The Uluru Statement from the Heart, delivered at the 2017 National Constitutional Convention, addressed to the Australian public, called for support in the creation of constitutional reforms to build on changes made in the 1967 Referendum. Glen Sean Coulthard’s Red Skin, White Masks takes a difference stance on recognition for Indigenous peoples, specifically citing First Nations peoples in North America. In understanding the goals of the Uluru Statement and the arguments raised in Red Skin, White Masks, constitutional recognition may begin to address vital problems such as the dispossession of Indigenous land and lack of inclusion in state politics, but its existence as part of the settler-colonial governance will always act as a deterrent for true decolonization.

This essay aims to critically reassess and, ultimately, rehabilitate exoticism, understood as a particular mode of cultural representation and a highly contested discourse on cultural difference, by bringing it into dialogue with cosmopolitanism. It offers a theoretical exploration of exoticism and cosmopolitanism alongside associated critical frameworks, such as the contact zone, autoethnography, authenticity and cultural translation, and brings them to bear on two awardwinning films that aptly illustrate a new type of exoticism in contemporary world cinema. Using Tanna (Martin Butler and Bentley Dean, 2015) and Embrace of the Serpent (Ciro Guerra, 2015), both made in collaboration with Indigenous communities, as case studies, this essay proposes that exoticism is inflected by cosmopolitan, rather than colonial and imperialist, sensibilities. It therefore differs profoundly from its precursors, which are premised on white supremacist assumptions about the Other which legitimised colonial expansion and the subjugation of the subaltern. By contrast, the new type of exoticism challenges and decentres Western values and systems of knowledge and aligns itself with the ethico-political agendas of cosmopolitanism, notably the promotion of crosscultural dialogue, an ecological awareness and the empowerment of hitherto marginalised communities.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Ultramicrotomy produces plastic deformation in the surfaces of microtomed TEM specimens which can not generally be observed unless special preparations are made. In this study, a typical biological composite of tissue (infundibular thoracic attachment) infiltrated in the normal manner with an embedding epoxy resin (Epon 812 in a 60/40 mixture) was microtomed with glass and diamond knives, both with 45 degree body angle. Sectioning was done in Portor Blum Mt-2 and Mt-1 microtomes. Sections were collected on formvar coated grids so that both the top side and the bottom side of the sections could be examined. Sections were then placed in a vacuum evaporator and self-shadowed with carbon. Some were chromium shadowed at a 30 degree angle. The sections were then examined in a Phillips 300 TEM at 60kv.Carbon coating (C) or carbon coating with chrom shadowing (C-Ch) makes in effect, single stage replicas of the surfaces of the sections and thus allows the damage in the surfaces to be observable in the TEM. Figure 1 (see key to figures) shows the bottom side of a diamond knife section, carbon self-shadowed and chrom shadowed perpendicular to the cutting direction. Very fine knife marks and surface damage can be observed.

Iron is believed to play an important role in the pathogenesis of ischemic injury. However, the sources of intracellular iron in myocytes are not yet defined. In this study we have attempted to localize iron at various cellular sites of the cardiac tissue with the ferrocyanide technique.Rat hearts were excised under ether anesthesia. They were fixed with coronary perfusion with 3% buffered glutaraldehyde made in 0.1 M cacodylate buffer pH 7.3. Sections, 60 μm in thickness, were cut on a vibratome and were incubated in the medium containing 500 mg of potassium ferrocyanide in 49.5 ml H2O and 0.5 ml concentrated HC1 for 30 minutes at room temperature. Following rinses in the buffer, tissues were dehydrated in ethanol and embedded in Spurr medium.The examination of thin sections revealed intense staining or reaction product in peroxisomes (Fig. 1).

The advances in recent years in the microanalytical capabilities of conventional TEM's fitted with probe forming lenses allow much more detailed investigations to be made of the microstructures of complex alloys, such as ferritic steels, than have been possible previously. In particular, the identification of individual precipitate particles with dimensions of a few tens of nanometers in alloys containing high densities of several chemically and crystallographically different precipitate types is feasible. The aim of the investigation described in this paper was to establish a method which allowed individual particle identification to be made in a few seconds so that large numbers of particles could be examined in a few hours.A Philips EM400 microscope, fitted with the scanning transmission (STEM) objective lens pole-pieces and an EDAX energy dispersive X-ray analyser, was used at 120 kV with a thermal W hairpin filament. The precipitates examined were extracted using a standard C replica technique from specimens of a 2¼Cr-lMo ferritic steel in a quenched and tempered condition.

Zirconia (ZrO2) is often added to ceramic compacts to increase their toughness. The mechanisms by which this toughness increase occurs are generally accepted to be those of transformation toughening and microcracking. The mechanism of transformation toughening is based on the presence of metastable tetragonal ZrO2 which transforms to the monoclinic allotrope when stressed by a propagating crack. The decrease in volume which accompanies this transformation effectively relieves the applied stress at the crack tip and toughens the material; microcrack toughening arises from the deflection of a propagating crack around sharply angular inclusions.These mechanisms, however, do not explain the toughness increases associated with the class of composites investigated here. Analytical electron microscopy (AEM) has been used to determine whether solid solution effects could be the cause of this increased toughness. Specimens of a mullite (3Al2O3·2SiO2) + 15 vol. % ZrO2 were prepared by the usual technique of mechanical thinning followed by ion beam milling. All observations were made in a Philips EM400 TEM/STEM microscope fitted with EDXS and EELS spectrometers.

Interphase sliding is an important phenomenon of high temperature plasticity. In order to study the microstructural changes associated with it, as well as its influence on the strain rate dependence on stress and temperature, plane boundaries were obtained by welding together two polycrystals of Cu-Zn alloys having the face centered cubic and body centered cubic structures respectively following the procedure described in (1). These specimens were then deformed in shear along the interface on a creep machine (2) at the same temperature as that of the diffusion treatment so as to avoid any precipitation. The present paper reports observations by conventional and high voltage electron microscopy of the microstructure of both phases, in the vicinity of the phase boundary, after different creep tests corresponding to various deformation conditions.Foils were cut by spark machining out of the bulk samples, 0.2 mm thick. They were then electropolished down to 0.1 mm, after which a hole with thin edges was made in an area including the boundary
