A reference sample of dental and oral nonmetric traits should represent its biological population from which it stems. The presence of individuals born at different times, different regions, and separate countries in the Coimbra-identified cranial collections provides the test of whether this sample reflects the biological continuity of this Portuguese sample among the late modern (early industrialization, nineteenth century) to early contemporary (early demographic transition, first half of the twentieth century) population of this region of central Portugal. The Coimbra collections were scored for 61 traits using methodology by Hauser and De Stefano (1989), Turner et al. (1991), Scott and Turner (1997), Irish (1998), and Marado and Silva (2016). The 600 individuals in the sample were divided by generation, region, and nationality. Their phenetic diversity was tested with principal component analysis and with the mean measure of divergence statistic. The proximity between the subsamples was generalized, and it mimicked previous genetic marker results. Some small subsamples hindered conclusions; nevertheless, this Coimbra sample is considered a reliable dental reference sample for the Portuguese late modern/early contemporary population.  相似文献

The aim of this work is to characterize the original concrete from Roman buildings for public spectacles, theatre and amphitheatre, from Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required for a reliable restoration and preservation of these ancient monuments. The concrete was studied through mineralogical (optical polarized microscopy and X-ray diffraction) and petrophysical (bulk and real density, open porosity to water and Hg, mechanical strength and ultrasonic velocity) analyses. With this work, it is possible to fill the gap that exists in this field and the characterization of the materials used in the Roman concrete from these two buildings, never previously studied, despite the significance of this archaeological ensemble, declared a World Heritage Site by UNESCO in 1993. The results allowed us to determine the composition of the Roman concrete and to infer the provenance of the aggregates used in these monuments.  相似文献

This article aims at presenting and discussing the strategies for updating the finite element numerical modeling of stone masonry arch bridges using operational modal analysis. The study comprehended three bridges: two old ones, the St. Lázaro and the Lagoncinha bridges, and a recently constructed bridge in Vila Fria, Portugal. Updating of the bridge models is performed by comparing the numerical and experimental modal parameters. Three-dimensional detailed numerical models are used to perform modal analysis of the bridges. Experimental modal identification of the bridges is based on the measurement of their acceleration responses during normal operation. The assigned material properties are also based on available results obtained from in situ and laboratory tests and on the results of visual inspection and historical research carried out for both old bridges.  相似文献

In this article, I explore the parallel responses of two groups of colonial subjects who were confronted with the institutional changes that occurred in the context of Enlightenment ideas in eighteenth-century Mexico: creole clerics headed by the Jesuit Francisco Javier Clavijero; and native religious men who petitioned to colonial authorities and the Crown for additional spaces for the education of indigenous men. I explore some of the interactions between creole clerics—often referred to as creole patriots—and native elites in the schools of central Mexico, and efforts by indigenous noble men to broaden the opportunities for natives to join the ranks of the Church and to receive a higher education. To this end, I build on the scholarship that has made evident how the hegemonic program of Bourbon reforms, which was inspired by the Enlightenment, was not a top-down plan implemented successfully and equally across the continent but rather a series of contested interpretations. This article contributes to the recent shift in the scholarship on the Enlightenment that acknowledges cross-cultural global exchanges by arguing that certain groups of natives in central Mexico, and a particular group of American-born clerics, participated actively in building a pragmatic version of the Enlightenment that responded to their local realities and contributed to a globalized understanding of enlightened ideas.  相似文献

This article breaks new ground in examining how “new Irish” immigrant women have responded to the collapse of Ireland’s Celtic Tiger economy and the different forms of gender discrimination and marginalisation they face both within their minority ethnic communities and the Irish host society. It approaches Ebun Akpoveta’s Trapped: Prison Without Walls (2013) as an exemplary work of fiction which exposes unresolved injustices and inequalities suffered by immigrant women. Akpoveta creates a narrative that complicates previous representations of cultural encounters between newcomers and long-established members of Ireland’s host society, not least because her Nigerian female protagonist arrives as a postgraduate student rather than an asylum seeker or refugee. She fictionalises female experiences of marginalisation, gender-based violence and family dysfunction within an all-Nigerian family that outwardly appears to be a model of integration and social inclusion in an open and welcoming Irish multicultural society.  相似文献

A new, refined chronology for graves and grave‐goods in Anglo‐Saxon England has revealed a marked increase in well‐furnished female burials beginning in the second quarter of the seventh century. The present study considers what gave rise to this phenomenon and concludes that the small number of royal nuns and abbesses who figure so prominently in written accounts of the Conversion were part of a wider, undocumented change in the role of women that began several decades before the founding of the first female houses. It is argued that these well‐furnished graves reflect a new investment in the commemoration of females who came to represent their family's interests in newly acquired estates and whose importance was enhanced by their ability to confer supernatural legitimacy onto dynastic claims.  相似文献

ABSTRACT

Teresa de Jesús (1515–1582) lives in a patriarchal society opposed to the intellectual and spiritual development of women, something that she will not only not accept but also fight against, claiming a series of rights (the right to life, to expression, to autonomy, to the free development of her abilities, to have an active role in the Church, to relate to God through prayer, etc.) in spite of the restrictions of censorship and the cloud of suspicion that hung over her for being a mystic, the founder of convents, and the daughter and granddaughter of a converso. Furthermore, Teresa, with her reforms, would present an alternative life for women, as her convents would be spaces for freedom and women's solidarity.  相似文献
