Around the mid-nineteenth century, D. F. Sarmiento introduced in Argentine literature the duality of “civilization and barbarism,” assuming that it was, at that time, an inescapable model in the analysis of society. Early in the 1880s, when the “conquest of the desert” came to an end and conflicts between city inhabitants and their urbanistic and “civilizing” urban plannings, vis-à-vis the rural populations that assumedly resisted change, worsened, the model acquired a new meaning. Taking one particular case of analysis, the foundation of the city of La Plata in lands owned by the Estancia Iraola, this paper uses archaeology to explore the limitations and falsehoods of such duality, jointly with the assumption of a simplistic relation of determinism between an environment and a particular human group.  相似文献

This article describes the important discovery of a Late Bronze Age gold torc that was unearthed in a field of Acehúche (Cáceres, Spain). It was buried underneath some rocks at a site near a river crossing over the Tagus river. In its immediate vicinity, archaeological remains dating from the Copper Age to the Late Bronze Age have been found, which indicates the long use of this crossing. Until recently here, there existed a ferry and a chapel; and the place went by the toponym of the Dehesa de San Cristóbal. Legend too has it that the water from the river had curative properties. All of these components have maintained the sacred nature of the spot, otherwise transformed over the course of time, and reflect an earlier sacred landscape with quite ancient roots.  相似文献

Salt crystallization is a major cause of degradation in old buildings. One of the issues that stills need clarification is regarding the influence of the salts on the capillary absorption and subsequent drying of porous building materials. This article presents an experimental study that included capillary absorption and evaporative drying tests on two types of material (lime mortar and ceramic brick) using pure water or saturated solutions of six salts (sodium chloride, sodium sulfate, sodium nitrate, sodium carbonate, potassium nitrate, or potassium carbonate). The results of capillary absorption agree only roughly with the linear relationship, predicted by theory, between sorptivity and the square root of the ratio between viscosity η and surface tension σ of the solution (σ/η)1/2. This poor agreement is probably due to material heterogeneity. The drying dynamics was regular and showed little dispersion between specimens, but only for the uncontaminated materials. Indeed, the drying dynamics of the salt contaminated materials was often irregular or diverged among similar specimens, and the same happened with their salt decay patterns. The main conclusion is that soluble salts can amplify the effects on drying of the small structural heterogeneities that porous building materials normally depict.  相似文献

Sagasti, A.J., García Massini, J., Escapa, I.H., Guido, D.M. & Channing, A., August 2016. Millerocaulis zamunerae sp. nov. (Osmundaceae) from Jurassic geothermally influenced wetland environments of Patagonia, Argentina. Alcheringa 40, xxx–xxx. ISSN 0311-5518

A new species of Millerocaulis Erasmus ex. Tidwell emend. Vera is defined based on several permineralized stems recovered from geothermally influenced chert deposits in the Middle–Late Jurassic La Matilde Formation (Santa Cruz, Argentina). Millerocaulis zamunerae sp. nov. is characterized by the presence of an ectophloic dictyoxylic siphonostele, inner parenchymatic and outer sclerotic cortices, homogeneous sclerotic ring in the petiole bases, two masses of sclerenchyma lining the concavity of the petiolar vascular bundle, petiolar inner cortex with sclerenchyma strands in the outermost petiole cycles and stipular wings having one large and several smaller sclerenchyma bundles. Millerocaulis zamunerae inhabited geothermal wetlands and other hot-spring-related sedimentary facies associated with the La Bajada epithermal deposit. Reference to active geothermal wetlands, analogous living plants and other fossil hot spring ecosystems suggest the plant’s tolerance of physico-chemical stressors including elevated temperature, pH, salinity and phytotoxic metals/metalloids. Millerocaulis zamunerae thrived in wetlands preserved in the Jurassic geothermal systems of Santa Cruz Province, the same kind of environment in which Equisetum thermale Channing et al. was recorded previously.

High-tech development has been broadly accepted as a prominent matter of regional development policies and plans at the global level. Strategies to enhance it have evident implications for spatial planning policies, plans and visions. Consequently, careful attention should be paid to the role that spatial planning policies play in the national and regional efforts to advance high-tech development in a particular place. This study addresses the relationship between the spatial planning system and high-tech development, searching to explain the spatial implications resulting from this relationship. It approaches the topic by comparing high-tech development experiences in the Netherlands and Taiwan from an institutional perspective. Although both countries have used a range of spatial strategies for economic growth through high-tech development, the results show that their different institutional settings, power relations between different levels of government and conceptions of science park have led to the implementation of two very distinct spatial strategies, shaping different spatial patterns of high-tech development clustering in these two regions. The findings demonstrate the potential of the institutional approach to study international planning issues, and contribute to theories of high-tech development and spatial planning.  相似文献

Scholarly literature on interpersonal relationships between tourist women and local men has been largely discussed under the heteronormative framework of love and sexuality. However, the plenitude of ways in which these intimacies manifest themselves requires that we pay attention to the manifold forms of heterosexual relatedness that these intimacies generate. This article considers how intimate liaisons between Western women and Balinese men that commenced as holiday romances in Bali transform into unruly relationality and transnational motherhood. Focusing the analysis on women's narratives, the article explores how subjects engage in the production of sexual, reproductive, social and economic forms of transnational relatedness wherein the mother and child live permanently in the women's country of citizenship while the Balinese father remains in Bali. Rather than aspiring towards a monogamous relationship and cohabitation as heteronormativity prescribes, the article demonstrates how these non-conventional, transnational families perpetually challenge the nuclear family norm, boundaries of normative motherhood and dichotomies of home versus away.  相似文献

Angoche was an important historic trading port on the northern Mozambique coast. A maritime archaeological survey was undertaken of the islands and mainland to study Swahili trade, clarify the sequence of settlement development and record the exploitation of resources during the medieval and post-medieval periods. Previous archaeological investigations have revealed local ceramics from the early second millennium AD and imports from the late fifteenth century. According to oral traditions and ancient sources, Angoche’s growth is associated with the arrival of coastal settlers from Kilwa in 1485. The survey revealed evidence for occupation dating from c. AD 500 and trading evidence from the late first millennium AD. Artefacts from the thirteenth to sixteenth century on the islands are similar to those found at Kilwa and Sofala, which shows a link to Kilwa earlier than the oral traditions and the name of one of the Angoche Islands ‘Quilua’, is Kilwa in Portuguese. The islands are well resourced in terms of rice, mangrove wood, seafood and farmland and offer sheltered inlets and access to the coastal trade route. The name of Angoche relates to a port of call and the presence of ninth-tenth-century- storage vessels from southern Iran supports this theory. Traded glass and ceramic artifacts and beads increase from the late medieval period revealing that Angoche became an important and wealthy entrepôt. The lack of coral limestone and reef coral, on the sandy Angoche Islands, indicates some building materials would have had to have been imported. Although many buildings would have been made of wood, some stone ruins are likely to have been demolished and burnt to make lime. The original stratigraphy of many sites has been destroyed by aeolian and marine processes but the survey has shown that valuable information on settlement location and ethnographic practices can still be recovered.  相似文献

Abstract

Taking into account the course of cultural policy in democratic Portugal, and against the backdrop of the international crisis of 2008 and the sovereign debt crisis of 2011, this article seeks to interpret recent changes in the cultural sector in Portugal. Using both qualitative and quantitative methods it focuses on three main aspects: institutionalisation of democratic cultural policy; government funding; cultural organizations and facilities. The 2008 crisis put an end to a period in which investment tended to grow. We place Portugal in the broader European context, concluding that the Portuguese cultural scene may once again diverge from that of other European countries.  相似文献

This study aims to understand how postcolonial identities were performed in the negotiations that led to the new climate agreement signed in Paris in December 2015. Based on interviews, the analysis of documents and participant observation of the negotiations it was possible to identify the legal, economic and scientific discourses mobilised by both global North and South countries. In all three discourses, it was possible to identify a systematic effort of the Northern parties to unmake the identity of Southern parties as ‘developing countries’ as a way to erase the ontological difference between emerging and established industrialised economies. At the same time, in the context of the convention Southern parties reaffirmed their identities as ‘developing countries’ and demanded from the North a strong commitment to tackle climate change and the transfer of more financial resources to the South. In this process, it was also possible to identify an inversion of the position usually taken by mainstream and critical postcolonial scholars that see the deconstruction of categories such as ‘developing countries’ as key for the emancipation of the global South. Finally, this invites postocolonial scholars to look more closely at how postcolonial identities are being instrumentalised, discursively and politically.  相似文献

Social mobilizations that are devoted to contesting development and creating alternative economic arrangements conducive to the pursuit of a dignified life have recently sprung up. Not only do they criticize the current state of affairs but they actively seek and experience new ways of living, inspired by what Bloch calls the anticipatory consciousness of the ‘not‐yet‐become’, that is, another reality not yet materialized but which can be already experienced. This article argues that these mobilizations are not adequately captured by the term ‘social movements’. The uniqueness of these mobilizations requires a conceptual and epistemological turn that is able to accommodate the post‐development critique of development as well as their emancipatory dimension. We propose to name them ‘hope movements’ to account for the collective action directed to anticipate, imperfectly, alternative realities that arise from the openness of the present one. We conclude by discussing the political relevance of hope movements for the pursuit of the good life as an alternative to development.  相似文献
