This collection translates some of the work of the influential Black Brazilian thinker and activist Beatriz Nascimento (1942–1995) for the first time into English, in collaboration with her only daughter, Bethânia Gomes. Historian, poet, theorist and organiser, Beatriz Nascimento was a key figure in Brazil’s Black Movement until her untimely death in 1995. She dangerously wrote at the height of Brazil’s Military Dictatorship (1964–1985), and theorised extensively on the Black condition in Brazil; the unique experience of Black women; and quilombos—Brazilian maroon societies that she imagined as spaces of both historical and contemporary fugitivity. Following Alex Ratts, this introduction outlines her contribution to radical geography, in particular Black geographies, territoriality and embodiment. It also positions Nascimento within the trans‐Atlantic Black radical tradition. We present two of Nascimento’s essays in translation here. The first, “The Concept of Quilombo and Black Cultural Resistance”, introduces a crucial strand of her scholarly work, on the history and socio‐political significance of quilombos (maroon communities). The second, “For a (New) Existential and Physical Territory”, shows Nascimento in a different mood: philosophical, reflective and iconoclastic. In addition, two of her poems—“Dream” and “Sun and Blue”—are also translated here for the first time.  相似文献

The full release and circulation of excavation results often takes decades, thus slowing down progress in archaeology to a degree not in keeping with other scientific fields. The nonconformity of released data for digital processing also requires vast and costly data input and adaptation. Archaeology should face the cognitive challenges posed by digital environments, changing in scope and rhythm. We advocate the adoption of a synergy between recording techniques, field analytics, and a collaborative approach to create a new epistemological perspective, one in which research questions are constantly redefined through real-time, collaborative analysis of data as they are collected and/or searched for in an excavation. Since new questions are defined in science discourse after previous results have been disseminated and discussed within the scientific community, sharing evidence in remote with colleagues, both in the process of field collection and subsequent study, will be a key innovative feature, allowing a complex and real-time distant interaction with the scholarly community and leading to more rapid improvements in research agendas and queries.  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 recent decades in Europe, municipalities have promoted many poorly qualified and widespread industrial parks. These policies have caused various problems such as oversupply of industrial land, obsolescence and high vacancy rates. The future of these sites is uncertain and has become a key issue in planning. Nowadays, policies are focused on upgrading these sites and on implementing regional coordinated practices. This paper describes a methodological approach to identifying a subregional network of industrial parks in the Ave valley, Portugal. The network is based on the parks’ attractiveness and has the purpose of supporting planning policies in terms of upgrading and providing new sites. The approach was based on a multi-criteria analysis whereby the parks were ranked according to their attractiveness considering their coverage in terms of infrastructures, services and accessibility. Results show that the majority of the existing and planned parks, even if upgraded, will not be very attractive and will be limited to a municipal scale due to structural problems related to their location and poor coverage. Moreover, the paper also discusses the challenges in implementing this planning approach at a subregional level. Despite the specificities of the case study, this methodology could be adopted in similar studies.  相似文献

The publication of the Confucius Sinarum Philosophus in Paris in 1687 represented the apex of the syncretic effort between Confucianism and Catholicism started by Matteo Ricci more than one century before. The present study draws attention to the heart of the text, which is the translation of three Confucian Classics: Daxue (The Great Learning), Lunyu (The Analects) and Zhongyong (The Doctrine of the Mean), where the contribution of Prospero Intorcetta (1625–1696) appears to be predominant.

This article will firstly offer an updated biography of Intorcetta and his mission to Europe. Secondly, it will summarize the long process that led to the publication of the Confucius Sinarum Philosophus. Finally, through a comparative analysis between the former translations and those published in the Confucius Sinarum Philosophus, this study will attempt to extrapolate and determine the contribution of Intorcetta, focusing especially on the way some key concepts of the Confucian philosophy and of the traditional Chinese thinking in general were rendered.  相似文献

This study uses data of about 9,000 apartment sales in Stockholm, Sweden, to assess the impact of crime on property prices. The study employs hedonic pricing modelling to estimate the impact of crime controlling for other factors (property and neighbourhood characteristics). Geographic Information System (GIS) is used to combine apartment sales by coordinates with offences, land use characteristics and demographic data of the population. The novelty of this research is threefold. First, it explores a set of land use attributes created by spatial techniques in GIS in combination with detailed geographical data in hedonic pricing modelling. Second, the effect of crime in neighbouring zones at one place can be measured by incorporating spatial lagged variables of offence rates into the model. Third, the study provides evidence of the impact of crime on housing prices in a capital city of a traditional welfare state, information otherwise lacking in the international literature. Our results indicate that apartment prices in a specific area are strongly affected by crime in its neighbouring zones, regardless of crime type. When offences were broken down by types, residential burglary, theft, vandalism, assault and robbery individually had a significant negative effect on property values. However, for residential burglary such an effect is not homogenous across space, and apartment prices in central areas are often less discounted by being exposed to crime than those in the city's outskirts.  相似文献

This study presents a method for predicting meagre (Argyrosomus regius) body size (total length) from otoliths and vertebrae recovered from archaeological sites. The method involves regression equations calculated from a reference collection of 36 meagre skeletons and 113 meagre otoliths (sagitta) and allows the simultaneous estimation of original body size and minimum number of individuals (MNI) from archaeological bone structures. We selected the following measurements to predict meagre body size: greatest dorso-ventral height, greatest mediolateral breadth, and greatest anteroposterior length of the vertebrae centra; maximum anteroposterior length, medial anteroposterior length, and dorso-ventral height of the sagitta. Our results show that the original body size of meagre can be accurately predicted from many bone measurements (r2 range: 0.921–0.992). We exemplify the use of the regressions in the assessment of size variation and MNI of meagre from four Portuguese Mesolithic sites. We show that regression results provide additional insight into the significant role that this fish played in the subsistence of coastal fisher-hunter-gatherers, who targeted medium-sized animals but were also capable of acquiring rather larger specimens.  相似文献

The paleopathological record of neoplastic conditions in the past is considered scarce. The detection of tumours in ancient populations is hindered by the quality and quantity of signs visible on the skeleton, the methodological approach, the preservation of remains, and by difficulties of differential diagnosis. The aims of this paper are to report the extensive and multiple osteolytic lesions observed in an adult male and to discuss the possible etiology of these lesions. The individual, a 71‐year‐old male who died in 1932, is part of the Coimbra Identified Skeletal Collection. Records indicate that he died of a ‘heart lesion’. The present study used macroscopic, radiological, and computerized tomography examinations to analyse the skeletal remains of the individual number 439. The type and pattern of the lesions detected, which were most prominent on the skull, were compared with both clinical and paleopathological diagnostic criteria for different nosologic groups. The differential diagnosis addresses problems expressed both in clinical and in paleopathological literature with regard to the difficulties in distinguishing metastatic tumours from multiple myeloma. The nature of the lesions represented by this individual precludes an exact diagnosis. Therefore, we employed a broader category, neoplastic condition, instead of choosing a more specific diagnosis that would likely have resulted in a misdiagnosis due to overlapping features on this individual's condition. Further investigations are necessary to establish more replicable indicators and to improve confidence in retrospective diagnosis of these types of conditions.
