Abstract

This paper deals with firearms that were employed by the Argentine army in frontier warfare between 1869 and 1877. Documentary information and archaeological assemblages from two contemporary military facilities — Fort General Paz and Fortín Algarrobos — are combined to characterize the armament in service during those years. This was a crucial period, during which a process of modernisation and standardisation of the army’s armament started, centred on the incorporation of Remington single-shot breech-loading rifles and carbines. However, the archaeological record shows that this process was slow and that an astonishing variety of older firearms (flintlocks, percussion smoothbores and rifles) remained in service, causing logistic and operative problems, and reducing the army’s combat effectiveness. The paper then discusses the impact of the incorporation of the Remington guns on frontier warfare, critiquing commonly held determinist characterisations, and placing the Remington’s effect in a broader political and economic context.  相似文献

A new microdomatid gastropod, Eopagodea sevillana gen. and sp. nov., is described from the Late Ordovician (pre-Hirnantian Ashgill) limestones of Seville, Ossa Morena Zone, Spain. Palaeozoic microdomatids lived in shallow-water environments and were restricted to warm-water regions. Occurrence of microdomatid gastropods in the pre-Hirnantian Ashgill limestones of the Cerrón del Hornillo syncline (Ossa Morena Zone, Spain) is interpreted as an example of an influx of warm-water faunal elements into the otherwise cool to cold climate of the Mediterranean region during a short-termed, pre-Hirnantian increase of palaeotemperatures. The Late Ordovician microdomatid genus Daidia Wilson, 1951, is revised and two new Late Ordovician (Ashgill) subspecies of Daidia cerithioides (Salter, 1859) are described: Daidia cerithioides sewardensis n. subsp. from the Don River area of the York Mountains, Seward Peninsula, western Alaska, and Daidia cerithioides wilsonae n. subsp. from the Little East Lake Formation of northwestern Maine.  相似文献

Archaeological examples of violence in prehistory have increased in recent years. The evidence, methodology employed and interpretation of the data have been diverse, but in each case the myth of the ‘peaceful past’ is questioned. This work provides new data on the issue from the north‐eastern Iberian Peninsula, associated with the Bell Beaker culture (c.2800–2350 cal BC). Material from two megalithic tombs, Can Gol I and Can Gol II (Barcelona Province), in particular a set of flint arrowheads, has been revisited. Use‐wear analysis on the arrowheads confirmed the presence of impact fractures. This indicates that the arrowheads were not funerary offerings, but that they entered the graves lodged in the bodies of the deceased. The data from the only site with evidence of massive death by violence in the neighbouring region (Costa de Can Martorell) reinforce the hypothesis of episodes of conflict and violence during prehistory. However, the interpretation of the nature of such violence remains open to debate: was it an act of warfare or an occasional skirmish? And is the image of the Bell Beaker warrior identified in other European contexts also applicable to this area?  相似文献

Samples of mortars and stone of Portal de ses Taules from the Renaissance city walls of Eivissa (16th century) were characterized using thermal analysis— thermogravimetry and derivative thermogravimetry (DTG)—x-ray diffractometry, and scanning electron microscopy. The granulometric fraction of particle size <63 μm was selected as representative of the binder, while the fraction 0.5–1 mm was taken as representative of the aggregate in order to characterize mortar samples. The results show that local materials were used. Lime was the main component of most of the samples tested. Thermal analysis revealed the hydraulic nature of the lime mortars. High amounts of sodium chloride were found in the samples analysed.  相似文献

This study is focused on the El Milagro mine (Asturias, Spain) and is part of a large‐scale effort on the measurement of the lead isotopic composition of Spanish copper ores from prehistoric mines in the provinces of Asturias and León, from which no data were available until recently. Lead isotopic values are compared to the published lead data from the El Aramo mine in the same region. The results show that both mines have a very similar lead isotopic composition, apart from some highly radiogenic samples in the El Milagro mine, which are clearly different from those previously reported for the Iberian Peninsula.  相似文献

Outright victories against urban elitisation are rare in the current urban revolution. This article highlights how urban elitisation is confronted in Chacao, the most elite and urban part of Venezuela. Initially it reviews how this urban elitisation created the main economic, political and military strongholds of the opposition to the Bolivarian revolution. Then, in contesting it, the urban and Bolivarian revolutions feed each other through women's participation in invited and invented spaces of citizenship. From such spaces, Chacao women in their settler's movement organised struggles of insurgent citizenship to stop elitist urban renewal agendas and develop further forms of insurgent urbanism to conduct an urban renewal from below and establish a New Socialist Community for 600 families. They emerged as a revolutionary class to implement Bolivarian policies addressing the inefficiency and opportunism of the bureaucratic state and contesting urban elitisation with an anti‐capitalist and anti‐imperialist insurgent urbanism.  相似文献

This paper examines the evolution of regional innovation policy in Emilia-Romagna and Valencia, two regions with similar economic features that implemented close innovation policies in the 1970s and 1980s. We investigate whether their similarities have led to parallel targets, policy tools and governance developments. We show that innovation policy in both regions suffered from the effects of privatization, budget constraints and changes to manufacturing during the 1990s and we highlight the consequences. Although Emilia-Romagna experienced deeper changes to its innovation policy, privatizations and/or the replacement of public funds promoted commercial approaches and induced market failures in both regions. The worst effects of these policies were the implementation of less-risky innovation projects, the shift towards extra-regional projects and markets, and the favouring of large firms.  相似文献

Risk communication programs (RCPs) can contribute to the improvement of community health in marginalized settlements by improving health-related information and practices. Yet, there is a need to include young people's concerns in the design and implementation of RCPs. This study analyses young peoples’ risk perceptions in the city of San Luis Potosí, Mexico, using visual methods such as drawings and photography. Research was conducted with 74 students from two deprived urban neighborhoods. Results indicate that the use of visual techniques enabled them to identify environmental health risks such as unhealthy sedentary habits and the exposure to hazardous items. We conclude that visual methods may help young people to critically reflect on everyday elements in their environment that affect their well-being. By giving them a voice in a reflexive way, visual methods may engage young people as key multipliers in the awareness raising process, and promote their sense of everyday agency.  相似文献
