Maranhão has the best documented slave trade in all Portuguese America. However, it is one of the least studied branches of the Atlantic slave trade. This article provides an assessment of the volume, routes and organisation of the slave trade to Maranhão, in northern Brazil. It shows that, although small in scale, the slave trade to Maranhão displayed important features concerning the routes and organisation of the Atlantic slave trade. Finally, because of the late European occupation and relative isolation, the slave trade to Maranhão offers ideal conditions for observing the rise and fall of African slavery in the New World.  相似文献

Abstract

In the face of enduring systemic racial disparities between Māori and non-Māori, we invite Pākehā health, education and social service professionals to review their ethical conduct and to enhance their political competencies to help transform racism. This paper examines how Pākehā became beneficiaries of racism and how libertarian discourses are used to distract attention away from the associated privileges. Based on experience in the anti-racism movement, we (the Pākehā authors) advocate for the grounding of Pākehā practitioners in a deeper understanding of colonial history. We invite closer attention to structural analysis as a means of gaining the understanding needed to strengthen political competence in order to avoid collusion with institutional racism. We make a case to develop co-intentional relationships with Māori through active whanaungatanga and the applications of the teachings of Freire as pathways for strengthened practice.  相似文献

This paper describes a comparative analysis of the official forms used for reporting occupational accidents within the EU-27 member states. The comparison is based on two analysis grids (coding schedule) created to that effect, which incorporate a set of evaluation criteria and an interpretation key. The results obtained in the analysis allowed for attention to be drawn to the relevant attributes of such forms in terms of their content and format/structure. It also revealed the main similarities and differences between each country, providing a complete assessment of the 27 member states. The discussion gives account of the level of implementation of the "new" Eurostat variables within the European Statistics of Accidents at Work (ESAW). Furthermore, the study shows that certain formats (structure of information fields) appear to facilitate completeness of the information collected. It has also demonstrated that the European harmonisation process is still far from completion, although the newcomer states seem to be adjusting quickly to the process. The findings of this study may bring useful insights to national authorities and European policy-makers, or to employers/enterprises wishing to implement their internal procedures aligned with the ESAW methodology. The scientific community is another interest group, whose research relies on official statistics, preferably comparable across all countries.  相似文献

The conversations surrounding an ephemeral home – left behind decades ago or perhaps never even visited – always and continually begs the question: why? Why do we constantly talk about geographies to which we have little or no connection with such nostalgia and fervor? Why do immigrants pick a distant space and mark that territory as home, even as we settle into the spaces we presently occupy and slowly begin the journey toward some form of assimilation? Framed by these questions, this essay attempts to articulate – through a multi-site analysis including interviews, literary and media texts – how identities are shaped through – and in relation – to the nostalgic longings of non-white immigrant experiences. The essay contends that this nostalgic longing is constructed as a response to racial relationships in the United States that identifies non-white, in this instance South Asian Americans, as aliens and others who should go back home.  相似文献

Objective. Our objective is to explain how scientists interpret less‐than‐certain scientific findings to inform policymakers' choices on controversial science policy issues. We focus on two particularly difficult policy cases concerning global climate change and low‐dose radiation protection. Methods. Our method is to analyze data from a unique multination survey of scientists to analyze the ways their views about what is scientifically correct are translated into judgments about appropriate policy. The surveys asked scientists, randomly drawn from U.S. and E.U. subscribers to the journal Science, to indicate the “most likely” relationships between greenhouse gas emissions and average global temperatures and between radiation dose and incidence of cancer in humans. Follow‐up questions asked for their judgments about appropriate policy targets for reductions in greenhouse gas emission and safety standards for radiation exposure. The data permit analysis of the relationships between scientific certainty and policy judgments in these two cases. Results. Our results shed light on when and how scientists reach precautionary policy conclusions, demonstrating that scientists' application of precaution is dependent on context. In the case of radiation protection, greater certainty is associated with less precaution. But with respect climate change, we found the opposite relationship. Conclusions. We conclude with a discussion of the implications for the role of scientists, and scientific advice, in the policy process.  相似文献

The use of weighted rankings to analyze complete blocks designs (Quade, 1979) is a practical way of recovering between-block information. A family of old and new test statistics can be generated by this procedure. Selection among these statistics and comparison with parametric and nonparametric competitors are based on expected significance level [ESL] in small designs (3 to 6 blocks, 3 to 5 treatments).  相似文献

In this study, we aim to develop a demand classification methodology for classifying and controlling inventory spare parts subject to stochastic demand and lead time. Using real data, the developed models were tested and their performances were evaluated and compared. The results show that the Laplace model provided superior performance in terms of service level, fill rate (FR) and inventory cost. Compared with the current system based on normal distribution, the proposed Laplace model yielded significant savings and good results in terms of the service level and the FR. The Laplace and Gamma optimisation models resulted in savings of 82 and 81%, respectively.  相似文献
