The theoretical premise of this paper is that place is an unbounded material, social and cultural agent within and through which practices of colonialism were enacted in British Columbia. Specifically, the places of British Columbia's 'Indian' residential schools, and the subjects who occupied them, are conceptualized as intimate sites nested within Canadian colonial and nation-building agendas that were predicated on policies of assimilation, enculturation or annihilation of indigenous people. Such conceptualizations allow for an understanding of both how colonialism was actualized against First Nations' peoples and how First Nations' peoples actively navigated and resisted that colonial project. In order to access experiences of residential school places, the article draws from published First Nations' testimonial literatures. It also draws from creative materials produced by students within the schools in order to understand how First Nations' students articulated against assimilative educational processes. The article concludes with a consideration of how nested place, First Nations' resistances, and Euro-colonial concepts of gender are circulating today with reference to a Dakelh woman (and former residential school student) under consideration for beatification in northern British Columbia.  相似文献

Excavations carried out in Cuma by the Centre Jean Bérard archaeologists have uncovered a large quantity of pottery. This study is focused on cooking ware and on internal red‐slip cookware, also known as Pompeian Red Ware (Rosso Pompeiano), dated from the first century bc to the first century ad . A comparison with the minero‐petrographic composition of beach sands collected along the Bay of Naples coastline highlights the provenance of the temper from the Somma‐Vesuvius area, marked by leucite‐bearing scoriae and garnet. Petrochemical analyses allow us to distinguish two main groups of pottery characterized by different technological options based on the amount of temper and on the type of clay. X‐ray diffraction and scanning electron microscope data demonstrate improved accuracy in the production of Rosso Pompeiano, especially with regard to firing control, which was in a prevailing oxidizing atmosphere and in a narrow thermal range, between about 800 and 900°C.  相似文献

Torres et al. (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA‐21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre‐treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.  相似文献

Although characterized by low seismicity, the Monferrato area of north‐western Italy was affected by earthquakes, of magnitude M5.1 and M4.8, in 2000 and 2001. At the same time, marked changes were recorded in water temperature and chemistry in several wells within the epicentral area. In May 2004, an automatic network for the continuous monitoring of groundwater was installed in selected wells to study the phenomenon. Here, we report on data collected during a 3‐year period of groundwater monitoring. During the first year, episodes of water heating (by up to 20°C) were observed in one monitored well. The temporal analysis of the seismic activity recorded in the area revealed as almost all seismic events occurred during the period of elevated water temperatures. The similar timing of earthquakes and groundwater‐temperature anomalies suggests that both may be triggered by the same processes acting in the crust.  相似文献

Lead isotope ratios in ore bodies and magmatic rocks depend in a complex way on several a priori independent parameters, including the geological age of the tectonic province in which the ores and magmas formed and its U/Pb (μ) and Th/U (κ) ratios, two very sensitive parameters characteristic of metal sources. All these parameters are entangled in hard‐to‐read Pb isotopic ratios. With respect to the commonly used fingerprinting techniques, which rely on the comparison of raw isotope ratios, the main motivation for the present work is to provide a method for making geologically and geochemically educated guesses about metal provenance even in the absence of isotopic data on reference ores. It shows how to unscramble a geological model age and μ and κ information from isotopic measurements. This approach brings to light a new organization of the Pb isotope database and an untapped wealth of information that can be used for provenance studies and other archaeometric purposes. We provide expressions with which to calculate these parameters and, using literature data, demonstrate how Pb isotopes in ores and magmas define clear zones in the silver‐rich provinces of the Central Andes. We further show how the geological model age and μ and κ values fingerprint production areas in 16th–18th century silver coins minted in Mexico and South America. Finally, we use Pb isotopes to illustrate how the Reconquista of the Emirate of Granada (1482–91) and the seizure of the Betic silver mines are reflected in the silver coins of the Catholic Monarchs.  相似文献

Seismic vulnerability of unreinforced masonry buildings is studied by means of simplified out-of-plane collapse mechanisms that take into account connections with transversal walls. According to experimental evidence, the analysis assumes that failure is reached with a rigid body motion of a part of the facade that falls down. Two classes of mechanism are examined: the overturning of the facade due either to a vertical crack at the connection or a diagonal crack on the transversal wall, both defined resorting to a simple model of masonry fabric, viewed as a regular assembly of rigid blocks and elastic plastic joints with friction but no cohesion. The use of simplified mechanisms give rise to an explicit evaluation of the seismic resistance to changes in the geometry and in the masonry fabrics, that could be used by practising engineers. This formulation is developed for both static horizontal actions and ground velocity peak, in the belief that the latter probably gives a better approximation of seismic action, while also providing, by comparison with the results of static forces, an estimate of the behaviour factor for unreinforced masonry. Eventually, the analytical forecasts are compared with numerical results obtained by means of the distinct element method.  相似文献

Since the mid-1990s the UN, in tandem with major western powers, has embarked upon an ambitious effort of peace support operations in Africa. The results of what we may call the 'Annan experiment' are not yet in. But there are good reasons to fear that, in many African countries, such peace operations have defend normative outcomes that are beyond realistic expectation, so that they can never hope to 'succeed'. This article examines the political and economic functioning of fragile African states using the lens of a 'political marketplace' in which local elites seek to obtain the highest reward for their loyalty, over short time horizons, within patrimonial systems. In such systems, political institutions are incapable of managing confect, which means that standard peacemaking efforts and peacekeeping operations do not align with domestic possibilities for settlement. To the contrary, external engagements can so distort domestic political markets that they obstruct national political bargaining and result in an open-ended commitment to peacekeeping in countries such as the Democratic Republic of Congo and Sudan.  相似文献

An interpretation of the features surrounding the complex and deliberate closure ritual in several collective Middle Neolithic tombs of the Ambrona Valley (Soria) is offered, where fire and quicklime played a major role in the rituals. The problems involved in the excavation and the understanding of this complex burial evidence are examined. The roles they might have played in the context of the important social and economic transformations of the local Neolithic groups around the end of the fourth millennium cal BC are also analysed. It is argued that the burial rituals tried to reinforce group solidarity at a time when the community was beginning to fragment, as the economic systems began to yield a surplus production whose management would have altered political structures.  相似文献

A late pre-Islamic burial at al-Khatt, U.A.E.   总被引:1,自引:1,他引:0  
Gravegoods comprising local and imported pottery together with iron arrowheads were 'rescued'from a burial at al-Khatt, U.A.E., in 1993. Their relation to the chronology established at Mleiha suggests that they date from the late 3rd to early 2nd centuries BC, a period as yet little known in the Emirate of Ras al-Khaimah.  相似文献
