As part of a larger project promoting the development of historical dendrochronology in the Iberian Peninsula, ship‐timbers from the Arade 1 wreck (mostly planking and framing elements), stored at the DANS/IGESPAR in Lisbon, were examined. Of these, 52 samples were identified as deciduous oak (Quercus subg. quercus) and two as chestnut (Castanea sativa). Of 24 timbers selected for dendrochronological research, 23 could be dated, placing the origin of the wood in western France and the felling of trees between AD 1579 and 1583. Their homogeneity suggests they are part of the original construction, which probably took place shortly after AD 1583. © 2012 The Authors  相似文献

I would hope that the nations of the world might say that we had built a lasting peace, based not on weapons of war but on international policies which reflect our own most precious values. These are not just my goals, and they will not be my accomplishments, but the affirmation of our nation's continuing moral strength and our belief in an undiminished, ever-expanding American dream. 1

This article examines the discourse of two American couples in the China trade regarding fidelity and sacrifice during the period in which the spatial confines of the Canton system gave way to the intensified interactions of the Treaty Port era. Before the Opium War, when the Qing court had mandated that Western husbands conducting business in Canton live apart from their wives, marital tension was accentuated by the separation from absentee husbands. In the subsequent Treaty Port era, enhanced spatial mobility of the couples did not assuage their concerns. Instead, intensified cross-cultural encounters allowed them to project their feelings and expectations on the “foreign other” as racial categories developed and their imperial proclivities began to escalate. Bringing the Western women in contact with elite Chinese and other Western women only aggravated their agitation as they faced their Chinese counterparts, whom they readily construed as competitors. The socio-political and spatial reconfigurations provided new dimensions to the discourse of fidelity and sacrifice. The voices of the American couples recorded here are those of individuals, but the underlying anxiety they articulated represented the growing pains of more intimate Sino-Western encounters.  相似文献

Alongside the burgeoning secular ideas on people and state during the Constitutional Revolution, a movement seeking a modern Islamic state, governed according to the shari'a, also emerged. This article studies the evolution of that movement in Isfahan, first by contrasting the experience of two brothers of very different ages, Aqa Najafi Isfahani and Haj Aqa Nurullah Isfahani, and examining the way the younger became receptive to the Pan-Islamic ideas then current in the Middle East. Second, the article considers in particular the political theory of Aqa Nurullah, which was influenced by his practical experience of institutional innovation in Isfahan. He argued that constitutionalism was implicit to Islam and saw it as generating wealth for Muslims. He also advocated many of the features of later Islamism, including the desire for a strong army.  相似文献

Lost after partial destruction by dredging in 1970, Arade 1 was a priority for the Centro Nacional de Arqueologia Náutica e Subaquática (CNANS). The upper part of the hull, lying over a 7-m-long area of the bed of the Arade river, was fully observed and recorded during the first two seasons (2001 and 2002) and dismantled in a third phase (2003). The 2004 and 2005 seasons aimed at the excavation, full recording and dismantling of the lower hull, briefly observed at the end of 2002. This second, detached, portion of the hull, was buried in the sediment and corresponds to midships.

Segregation measures based upon data gathered at different geographical levels cannot provide consistent results because of the scale effect under the Modifiable Areal Unit Problem (MAUP) umbrella. This paper proposes a framework, which decomposes segregation attributable to different geographical levels, to conceptually link segregation values obtained from multiple geographical levels together such that differences in segregation values among levels are accounted for. Using two different indices, the dissimilarity index D and the diversity index H, this paper illustrates the decomposition methods specific to these indices. When these indices are decomposed, local measures of segregation pertaining to multiple geographical levels are computed. These local segregation measures indicate the levels of segregation contributed by the local units and the regional units to the entire study area.  相似文献

Dimensional analysis, through the application of Buckingham's π-theorem, has been employed to formulate a functional relationship among a set of dimensionless products into an indeterminate homogeneous equation. In showing how dimensional homogeneity can be achieved for a given set of hydrologic variables involving the fundamental dimensions of mass, length, and time, the basic concepts and principles of dimensional theory are first presented; Buckingham's π-theorem is next stated and then applied to the set of hydrologic variables. A great many ways of arranging dimensionless groups were revealed in the course of deciding the most meaningful combination of dimensionless terms for the final equation.  相似文献

In 2017, the Philippine government boosted its campaign on Overseas Filipino Worker (OFW) reintegration, a set of programmes designed to aid returning Filipino labour migrants. In this paper, I examine migrant reintegration through the case of returned migrants to the province of Benguet, Philippines. Rather than use “sustainability of return” as main focus of assessment, I foreground instead the historical geographies undergirding the current reiteration of this migration policy. By doing so, I demonstrate how the “gambling” practices of returned migrants can be read as not an easy acquiescence to the neoliberal imperative for self-entrepreneurship encouraged by the Philippine state. In highlighting gambling as an embodied strategy emerging from and through imperial histories, I argue that migrant reintegration gets revealed as rehearsal of certain colonial logics that have oriented certain peoples to the labour of serial risk taking for survival. Close attention to return migrants’ gambling practices raises urgent questions regarding the relentless push for entrepreneurship as development solution.  相似文献

This paper argues that policing be understood as a creative social force that reproduces important dimensions of earlier iterations of the colour line. The paper advances this argument by integrating findings from two distinct research projects: the first on the household financial losses that follow arrest by immigration officials in Tucson, AZ; and the second focusing on the everyday costs of policing and carceral supervision absorbed by residents of Philadelphia, PA. Together, data from these sites illuminate how exposure to policing exhausts emotional and material resources from expansive family and community networks of care and support. To theorise the connection between financial dispossession and the dispossession of future opportunity, we draw on a heuristic reading of the “thin blue line” symbol. We conclude by suggesting a need for closer attention to how contemporary state interventions drive patterns of dispossession and vulnerability that accumulate across various scales, sites, rhythms, and collectivities.  相似文献

Today pilgrimage is experiencing an increasing interest, although motives are notable changing. Sites along pilgrim routes normally profit in an economically way. But until today regional economic effects of even very small pilgrimage sites are underexplored. Therefore economic impulses of the pilgrimage site in Biberbach (Bavaria) were identified using interviews and calculations. According to that the 10,000 visitors per year generate nearly 30,000 € gross turnover and 0.5 jobs. So even small pilgrimage sites can obviously produce a notable increase of local EVA.  相似文献
