Background and aims: Since the 1990s in Argentina, a process of visibility and reemergence of aboriginal groups that were believed extinct by official history has been developing. This is the case of Comechingon people in Córdoba province. Furthermore, it is known that gathering of wild food plants is an ancient practice that contributes to the subsistence of many indigenous communities of the country. Within the framework of Food Sovereignty and Ethnobiology, the aim of this paper was to carry out a first inquiry into the use of wild edible plants by residents self-identified as members of Comechingon people of San Marcos Sierras (Córdoba). M&M: Semi-structured interviews and free listings were conducted to a representative from each of three Comechingon communities from this town. They were accompanied with the discussion of a photographic guide of species. Results: Thirty-four wild ethnotaxa were recognized. They correspond to thirty-two botanical taxa. 85% was native species and the rest was exotic. "Algarrobo trees" (Prosopis spp.) presented the greatest number of parts used and ways of consumption mentioned. Fruits were the most used vegetable parts, followed by flowers, leaves, cladodes, underground organs and resins. The last two, just like trees' leaves, had not been previously reported for the region. Likewise, different ways of gathering, conservation and culinary products were mentioned. Conclusions: Comechingon communities know and consume a wide variety of edible ethnotaxa of plants. We hope to contribute to the visibility of Comechingon culture and the consolidation of sovereign food systems. [ABSTRACT FROM AUTHOR]

This paper is part of a more comprehensive study in which I focus on teaching practice conflicts in Cordoba during the 90's, in the context of state reforms. Within this framework, on one hand I am interested in showing the real nature of official and pedagogic discourse around the educative reform; on the other hand, to discusse and leave open the possibility of thinking that there was a displacement of logical organization of the business sector to the educative area and also that the use of philosophical assumptions of onhism were being applied to other work areas. This factor had also a great influence on educative sphere as a part of global transformation and in consequence, it influenced national and provincial government discourse around that reform. Finally, this paper aims to suggest deeper analysis to follow on how those discourses were received among teachers, and the individual or collective resistance that they might have generated. This article points to answer three questions: Did the national and provincial government discourse about this educative reform point to change the organization of the teaching job and the teacher's profile? In what sense did they do that? And how did the teachers receive those government interpellations? [ABSTRACT FROM AUTHOR]

The archaeological evidence left by the humans who occupied the center of Argentina (com prising the present territory of the provinces of Cordoba and San Luis, Argentina), from the earliest settlements until the moments before the Spanish conquest, shows that these populations developed different strategies and adaptations to the environment over time. One such strategy is the production of lithic artifacts. This contribution specifically addresses the study of sequence of cores and reducing manufacturing bifaces by applying the methodology of the "non-typological" analysis to the study of debitage. These experiments were conducted as a result of the analysis of the lithic technology of archaeological sites located at the archaeological locality of Estancia La Suiza, in San Luis province. The purpose of this paper is to compare the flake debris produced by these experiments to better differentiate types of carving. These results are compared with the archaeological record, in order to better explain how past human groups made their tools, and what comprised the various stages in the process of reduction.

This paper presents and analyzes the archaeological data recovered in Guasapampa Valley (province of Cordoba, Argentina), which consists mainly of engraved and painted rock art panels. The forested mountain landscape has numerous species of trees and shrubs with edible fruits, but it is distinguished by a scarcity of water resources. During the late Prehispanic period (ca. 1400-400 B.P.) the Guasapampa Valley was occupied seasonally by groups established most of the year in the fertile valleys of the east, in agricultural oases up to 20 and 40 km away. The data recovered are significant because they allow us to understand the role of rock art as an active medium for the establishment, negotiation, and reproduction of certain social ties between producers and observers. In this regard, we assume a comparative perspective that allows us to identify particularities of the occupations of southern and northern sections of the valley, especially the features that define the contexts of production and meaning of the art. The differences identified in each section of the valley refer to contrasts and oppositions in the social practices surrounding and produced by this materiality. Thus, we consider the elements that support its definition on the one hand as a means to convey the significance of particular places among minimal affiliational groups who build an open, shared social landscape in the case of the southern section, and on the other hand as territorial markers in the north related to the existence of limits and restrictions on movement and access to resources, including seasonal water wells.

This paper presents the fracture toughness evaluation of the Ferreyra natural-gas pipeline, which has been in service in the city of Córdoba, Argentina, for more than forty years. For the pipeline under analysis, we obtained the critical stress- intensity factors (KIc of the pipe body and its weld seam, in a temperature range that included the lower part of the transition region, the upper shelf and the lower shelf. The determination of KIc was carried out indirectly, through empirical correlations between fracture toughness and standard Charpy V-notch impact test results. Because the wall thickness of the pipe under analysis did not allow the preparation of standard size Charpy V-notch specimens, impact tests were executed using subsize specimens. Impact energy results were converted to standard Charpy energy values using appropriate formulas. We show that the fractomechanical properties of the pipe weld seam are lower than those of the pipe body. [ABSTRACT FROM AUTHOR]

An intense process of state development, which generated social intervention and new capacities to produce public policies, took place since the forties in Argentina. This phenomenon was accompanied by trends towards an increasing centralization of the political power in the Executive branch of the government. Within this context, this paper attempts to explore these processes from a perspective based on a provincial jurisdiction, constructing an account that locates the history of this political entity within the more comprehensive story of the structuring of the Interventionist State. In order to achieve this purpose, the history of one provincial health department and its relationships with the Federal State organizations are analyzed, trying to unravel the reactions that the provincial state elaborated to the process of centralization of social policies, which accompanied the emergence of Peronism.
