This article claims that Santiago Mitre's 2011 film El estudiante stages a confrontation regarding the notions of politics and activism that polarize Argentina in the Kirchner era (and arguably Latin America in the so-called New Left in general). The mixture of documentary and fiction and the filmic images' particular combination of indexical and symbolic components unveil a tension between a practical notion that considers politics to be the result of either gestión or emotions, and an ideal notion that sees politics as a series of principles and concepts and sees activism as a morally subordinate sphere. Thus, on the one hand, the article breaks with a monolithic view of politics and activism during Kirchnerismo, unpacking a confrontation that can resignify these concepts. On the other, it helps to further understand how the mixture of documentary and fiction, which is quite typical in new Argentine cinema, can be read ideologically.  相似文献

This article analyses how neoliberal restructuring encouraged the use of participatory methods in agricultural research in Bolivia and how, at a later stage, participatory development initiatives had to be adapted to prevent conflicts with the post‐neoliberal views of farmer organizations. The article contributes to the debate on the normalization of participatory methods in agrarian development. Engaging with Foucault's work on governmentality and neoliberalism, our analysis goes beyond interpretations of participation which conceptualize it exclusively as a technology of power to discipline subjects. Drawing on a distinction between a liberal and a neoliberal moment in the restructuring of agricultural research, we study the case of PROINPA (Foundation for the Promotion and Research of Andean Products), a national NGO that was once part of the state system for agricultural research but was then privatized. Although PROINPA employed participation mainly to enhance managerial effectiveness, it also facilitated moments of participation from below. We argue that participation designed by this type of NGO is not just ‘technical’ as PROINPA professionals would like to perceive it, nor is it simply ‘political’ as critical views on participation hold. Instead it is malleable in the sense that each actor is involved in finding a new balance between technical, economic and political considerations.  相似文献

In the multidisciplinary project presented here, 12 known monastic grounds in Iceland were surveyed by a group of medievalists from different fields in the summers of 2009, 2010 and 2011. The aim of the survey was to increase knowledge of the Icelandic monastic garden and of the plants that were known and used there; to look for possible medieval cultural relict plants; to observe continental influence on the island; and to vitalize discussion and research. Landscape and plants were surveyed at the 12 monastic sites, and full botanical investigations made. Many of the plants found have a medieval past as medicinal and utility plants, and some of their properties may have been common knowledge to medieval Icelanders. An investigation of written sources and archaeological and archaeobotanical findings from excavated sites added to the investigators’ knowledge. So were there monastic gardens in Iceland in the Middle Ages? The answer is a rather confident yes. With all the evidence combined, the investigators were able to trace the deliberate use of medicinal, food and utility plants in the monastic contexts. Whether they were cultivated, tended in situ, gathered growing wild or imported is another matter. Continental influence was more evident than has previously been observed.  相似文献

The putting-out spinning of flax for merchants and weaving of kersey in house-manufactories for export are examples of new elements in wool production and manufacturing in late 18th-century Iceland. The import of luxuries also increased, and a broader group of inhabitants acquired these items from the monopoly-trade merchants. The article analyses how these elements can be understood in light of Iceland’s pre-industrial society. How did these changes become visible and have an impact on the country? Did changes in wool production and consumption signify new trends in 18th-century society, or should one interpret them as extensions of structures that already existed within what can be called the ‘Old Society’?  相似文献

The shift from the linear to the innovation system-based approach has resulted in the emergence of differentiated regional innovation policy. However, certain common presumptions bind these location-specific policies together. The set of information that is used to design these policies and the set of information excluded are fairly similar. The theoretical sections of this paper provide a critical review on the informational basis of regional innovation policy by contrasting the interpretations of the welfare effects of technological change in the utilitarian tradition and in Sen's capability approach. The empirical sections analyse the correspondence of the innovation capacity and welfare (well-being) situation in a Hungarian micro-regional data set. We conclude that the conventional informational basis of innovation policy is too narrow from a welfare perspective. Not only should the differences in the innovation systems, but also the peculiarities of the region's welfare situation be considered during the design of innovation policy.  相似文献

Fragments of charcoal are present in floodplain alluvium of the San and Strwi?? rivers in the Polish part of the Bieszczady Mountains, Polish East Carpathians. They occur as single clasts or in lenses in the basal part of fine-grained alluvium, together with unburnt wood debris, or in the middle part of the vertical sequence of the floodplain alluvium. 14 samples of charcoal from the upper courses of the San (ca. 50 km) and the Strwi?? (ca. 10 km) were dated with radiocarbon. The obtained dates fall mainly in the 15th through 19th century interval; only one sample is markedly older (9th–10th century). Taxonomic composition of the charcoal source wood was also studied and compared with that of coeval forests. Correlation of the charcoal age with the history of economic development of the studied region indicates that charcoal is of anthropogenic origin: older charcoal from intense slash-and-burn deforestation, while younger charcoal was produced by local industries.  相似文献

The purpose of this article is to explain and discuss the essential operational characteristics of the technology of power (sensu Foucault) perpetrated on the internal frontiers with the Indians in nineteenth-century Argentina. The conquest and colonization of the Pampas took shape in the establishment of military camp structures placed to create a defensive cordon, known as “the Indian frontier line.” These constructions were fortlets defended by gaucho cavalry squadrons (know as Blandengues during the Spanish period, and then Guardias Nacionales after Argentinean Independence). This process is known in Argentinean historiography as “the conquest of the desert.” This particular technology of power existed in this historical context and operated at every social level, impacting strongly on the lower classes that inhabited the incorrectly named “desert.” Its implementation in the military field enabled the existence of an array of micro-powers that surrounded the gaucho, called vago y malentretenido—“a vagrant and lingerer”—and their women's lives. The army as institution was the locus of various forms of coercion and old forms of punishment (such as the stakes, whipping, and public executions) most of which affected peasants, nonresidents, itinerant workers, and the rural youth. This schema was adopted in different areas: in the enrolment and discipline of the gaucho soldiers, in life in the fortlet-prisons, and in the ritualism of power. The alternative chosen by soldiers to evade this technology of power and the fortlet-panopticons was escape through desertion. The utility of those observations is demonstrated, because an important part of the area of research of historical archaeology that has developed with the greatest impetus in Argentina has taken fortlets as its subject of study.  相似文献

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.  相似文献
