Introduction: The paper "Moluscos de la Isla del Coco" (Mollusks of Cocos Island) published in the Revista del Colegio Superior de Señoritas (1935) is the translation to Spanish of one of the last works of Paul Biolley Matthey (1862-1908), Swiss naturalist that lived in Costa Rica. This article was one product of a malacological research carried out during a scientific expedition organized by the 'Instituto Físico- Geográfico Nacional de Costa Rica' (IFGN) in 1902 to Cocos Island, at a time when the country claimed its sovereignty both in this territory. Objective: To analyze the contributions of the article "Moluscos de la Isla del Coco" from the Social History of Science approach. Methods: Most of the researches that have applied this approach in Costa Rica analyze processes of institutionalization of scientific disciplines. The methodology used in these works was very useful for the analysis of the Biolley article, together with the information of historical data provided by other texts about Cocos Island and the development of scientific research in Costa Rica from a temporal perspective. In addition, tables were made to synthesize the classification of the species and genera studied by Biolley in Cocos Island to identify their provenance and the habitat in which they lived. Results: This study of Biolley constitutes a text of interest from the point of view of the Social History of Science, due to the descriptions it offers of the physical conditions of the territory of Cocos Island, of the different species of mollusks located in them and to the exchange of information with national and foreign scientists that show the participation of Biolley in scientific networks. Conclusions: The analysis of the information with the Social History of Science approach, concludes that the compilation of the flora and fauna permits a greater knowledge of the natural resources of the explored territories, in order to colonize them and integrate them into the economic dynamics of the Central Valley of Costa Rica. However, attempts colonize Cocos Island failed given the distance between this and the continent, in addition to the topographic conditions that prevent the permanent establishment of human populations and their productive activities.

The topic which deals with this paper is the construction of subjectivities through a dialogic reason in the elaboration of public policies by Chile, in the field of interculturality and the expression that it has in the teaching of history, specifically on basic education in the areas of high concentration of students from Aymará ethnic groups. Methodologically a structural analysis is applied in order to give an account of the perceptions of the main actors in a school, and thus investigate the inconsistency that can be generated with the International Labor Organization (ILO) Convention N°169.

Current paper analyzes the life and works of the cultural agent Cornélio Pires whose activities involved the conservation of the caipira culture, disseminating it through publications, recordings, sound tracks, spectacles (scenes, music, guitar and musical groups) and propagating it on the radio. Contrastingly to the intense transformations in São Paulo, representations of plantations and life in the hinterland were emerging. They are actually different scenes in which the people of the Brazilian interior are sometimes praised and at other times criticized. Within this context, the life, works and artistic productions of Cornélia Pires are discussed. [ABSTRACT FROM AUTHOR]

This paper is about the representations, practices and cultural expressions carried out by groups of Bolivian immigrants and their descendants in the cities of Olavarria, Tandil and Azul in the province of Buenos Aires, Argentina. For this purpose, the three case studies presented are analyzed based on the theoretical notions of identities and ethnic groups proper to the field of social anthropology. It thus seeks to contribute to knowledge about the construction of the identities of Bolivian immigrants in Argentina and, especially, to the discussion of those perspectives that propose the cultural assimilation of these groups into the host society.
