Studies on the mobility of past populations are useful in the interpretation of trade and lifestyle. Preservation of ancient paths is uncommon. In Tenerife, a volcanic island of the Canary Archipelago, ancient paths are still preserved, due to the dry climatic conditions and the presence of extensive lava fields in inhospitable areas of the Island. The Guanches who inhabited this island before the Spanish conquest, those surviving in the highlands after the conquest, and modern goatherders, utilised a still identifiable net of paths to access the central mountains. Clasts in the beds of these paths have suffered variable abrasion, depending on the time during which the path was used and on the number of people and/or animals that have walked on it. We estimated roundness of 1819 clasts collected at different parts of the net of paths crossing different lava fields of known antiquity. Significant differences in roundness of clasts among different parts of the paths allowed an inference about the relative importance of each of the paths constituting the net. Therefore, assessment of roundness of the clasts of the beds of paths may aid in the understanding of the migrations of people. 相似文献

This article proposes to analyse the relationships betweenanthropology andindigenism in Brazil. To do so it considers the migration process of indigenism as a form of knowledge from the Mexican political field to the Brazilian. It affirms that this kind of knowledge had its reception considerably inflected by «traditions of knowledge» for governing populations which developed from colonial sources through time. This analytical perspective is part of an anthropology of colonialism, since it takes as its object Brazilian public administration considering some of its aspects as technologies for the government of multicultural populations. 相似文献

Abstract
This paper primarily presents analyses from geophysical data and archaeological remains collected at one of a few known sites to the west of Lake Chad associated with fired-brick structures. It reports on previous fieldwork at the location, considers its alleged relationship with the early history of the Borno kingdom and then turns to present new data that provide fresh insights into the physical appearance, dating, material remains, economy and environment of the site. A brief discussion of the historical purpose of the fired-brick structures and the site itself concludes the paper. 相似文献96.

This paper examines skeletal and ancient DNA evidence in the study of suspected tuberculosis infection in the late pre-Hispanic and Colonial-era Lambayeque Valley Complex, north coast Peru (A.D. 900–1750). We integrate information on macroscopic lesion characteristics and distribution, radiographic and CT scan imagery, and analysis of Mycobacterium tuberculosis complex rpoB and IS6110 ancient DNA (aDNA) sequences. Destructive lesions were observed in the vertebral bodies of three precontact indigenous adult males, one colonial adolescent female, and in the cranium of a Colonial-period subadult. Assessment of lesion morphology and distribution led us to consider multiple diseases, but tuberculosis represents the most likely diagnostic option in all individuals. DNA was poorly preserved in all samples, but an IS6110 sequence was amplified in one precontact individual consistent with macroscopic diagnosis. These findings expand the geographic and temporal extent of tuberculosis to the late pre-Hispanic and Colonial north coast of Peru to highlight potential synergisms between diet, settlement patterns, and the evolution of Andean tuberculosis before and after European conquest. Moreover, this study helps focus several key questions in Andean tuberculosis research, including possible reassessment of the presence of the IS6110 sequence in the pre-Columbian Americas. Methodological considerations include differential diagnosis – especially with incomplete skeletons – and limitations of aDNA studies underscoring an approach integrating macroscopic, radiographic, and molecular lines of evidence in the paleopathological investigation of one of humankind’s most devastating and destabilizing diseases. 相似文献

The p‐regions is a mixed integer programming (MIP) model for the exhaustive clustering of a set of n geographic areas into p spatially contiguous regions while minimizing measures of intraregional heterogeneity. This is an NP‐hard problem that requires a constant research of strategies to increase the size of instances that can be solved using exact optimization techniques. In this article, we explore the benefits of an iterative process that begins by solving the relaxed version of the p‐regions that removes the constraints that guarantee the spatial contiguity of the regions. Then, additional constraints are incorporated iteratively to solve spatial discontinuities in the regions. In particular we explore the relationship between the level of spatial autocorrelation of the aggregation variable and the benefits obtained from this iterative process. The results show that high levels of spatial autocorrelation reduce computational times because the spatial patterns tend to create spatially contiguous regions. However, we found that the greatest benefits are obtained in two situations: (1) when ; and (2) when the parameter p is close to the number of clusters in the spatial pattern of the aggregation variable. 相似文献

If, deluded by general literary history, we only value what is ethical and responsible in classical Portuguese satire, forgetting that it can also contain individual arbitrariness aimed at the destruction of an object, we will miss the moments when, as in medieval satire, the factor of constitution seems to be the ruthless and immoral personalization of criticism of persons, institutions, or entities. The aesthetics of moderation ends up promoting a subtly saturated and concrete language that seems to pursue the annulment of the other rather than a corrective social function. In Mannerism we find the most aesthetically elaborate examples of satire that challenges destiny or God in relation to the evils that fall upon an impotent but insubstantial self before such sensitive questions of metaphysical morality, a satire whose classic style gives it an aesthetic dignity and textual model without exception. In this article, we will see the different paths of classic and Mannerist satire, using the works of poets such as Sá de Miranda, António Ferreira, Pêro de Andrade Caminha, André Falcão de Resende, and Fernão Rodrigues Lobo Soropita. 相似文献
