The Agote Map of Hainan Island,China: A Case Study for Cultural Dialogue in Eighteenth-Century Cartography

The idea of cartography as an example of Western imposition or process of cultural transfer is one that has long fascinated scholars interested in the margins of empires. This article analyses the maps in the possession of Manuel Agote, a Spanish factor in Canton at the end of the eighteenth century. The focus is on the use made by Agote of a Chinese map of Hainan, together with the European maps available already in China for commercial interests, and the way this reflects the cultural dialogue that was operating among local and foreign cartographers engaged in similar European mapping activities in the region.

一个自由主义者的痛苦抉择——1946年张君劢同意民社党出席"国大"动因探微

对于自由主义者张君劢来说,他同意民社党出席1946年由国民党一手包办的“国大”,是一个极其痛苦的抉择。他之所以这样做,客观原因．一是民社党生态的困窘．二是国民党投其所好．百般拉拢;主观原因．一是他的充满矛盾的自由主义理念。二是他的“宪法之父”的“宪政情结”．三是他的人格的分裂与异化。     

The China factor in US alliances in East Asia and the Asia Pacific 1

Any discussion of the United States' alliances in East Asia and the Pacific should include an understanding of the role that China plays in regional security in general, and the influence of such a role on the alliance system in particular. The 'China factor' in the contemporary US alliance system can be understood by asking the following questions: (1) what are China's perceptions of and concerns regarding the US alliance system as a whole and regarding specific bilateral military alliances of the US?; (2) where does China figure in the American post-Cold War worldview, and what role does the United States itself see its alliances playing in relation to China?; (3) to what extent are the current bilateral alliances of the US directed against China, in the view of US allies; and (4) how might the reshaping of the international security environ ment following the 11 September 2001 terrorist attacks in the United States affect China's perceptions and attitudes towards future alliance developments?     

Boiled versus unboiled: a study on Neolithic and contemporary human bones

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours.     

The origin of black pigmentation in a sample of Mexican prehispanic human bones

The study of black patches and spots in prehispanic bones of Tlatelolco and Tlapacoya is presented. The chosen characterization techniques, X-ray Fluorescence, X-ray Diffraction, Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, Infrared Spectroscopy and Gas Chromatography are complementary and they all conclude that the bone black pigment is constituted, mainly, by amorphous carbon and some mineral inclusions. Gas Chromatography and Infrared Spectroscopy show that the pigment is constituted by organic compounds as aromatic hydrocarbons, mainly bitumen. An explanation on how the spots were formed is proposed.     

Urban Centrality: A Simple Index

This study introduces a new measure of urban centrality. The proposed urban centrality index (UCI) constitutes an extension to the spatial separation index. Urban structure should be more accurately analyzed when considering a centrality scale (varying from extreme monocentricity to extreme polycentricity) than when considering a binary variable (monocentric or polycentric). The proposed index controls for differences in size and shape of the geographic areas for which data are available, and can be calculated using different variables such as employment and population densities, or trip generation rates. The properties of the index are illustrated with simulated artificial data sets and are compared with other similar measures proposed in the existing literature. The index is then applied to the urban structure of four metropolitan areas: Pittsburgh and Los Angeles in the United States; São Paulo, Brazil; and Paris, France. The index is compared with other traditional spatial agglomeration measures, such as global and local Moran's I, and density gradient estimations. El presente estudio introduce una nueva medida de centralidad. El índice de centralidad urbana propuesto (UCI, por sus siglas en inglés) es una extensión al índice de separación espacial (spatial separation index)(Midelfart‐Knarvik et al. 2000). El análisis de la estructura urbana resulta más preciso al usar el índice cuando se toma en cuenta una escala de continua de centralidad (que puede variar de un monocentrismo extremo a un policentrismo extremo) que cuando se considera una variable binaria (monocéntrica o policéntrica). El índex propuesto controla las diferencias de tamaño y forma de las áreas geográficas de las que se tienen datos, y puede ser calculada utilizando diferentes variables, como empleo y densidad poblacional, o tasas de generación de viajes. Las propiedades del índice se ilustran con conjuntos de datos artificiales simulados, y se comparan con otras mediciones similares en la literatura ya existente. Posteriormente, el índice es aplicado a la estructura urbana de cuatro áreas metropolitanas: Pittsburgh y Los Ángeles, en EEUU; San Pablo, en Brasil; y París, Francia. Finalmente, se compara el índice con otras mediciones tradicionales de aglomeración espacial, como el índice de Moran local y global, y estimaciones de gradiente de densidad. 本文介绍了一种度量城市中心性的新方法,提出的城市中心性指数（UCI）是对空间分离指数的扩展。当涉及到中心性规模（从极单中心到极多中心）,不仅仅是二元变量（单中心或多中心）,城市结构则需更加精确的测度。本文构建的指数可以通过数据可获取的不同大小和形状的地理单元控制,并通过不同变量（如就业与人口密度或者旅次产生率）测算得到。该指数的属性可以通过人工数据集的模拟示例说明,或者通过对比已有文献对相似指数的阐述加以说明。然后,通过将该指数应用于全球四个大都市区（美国匹兹堡和洛杉矶、巴西圣保罗和法国巴黎）的城市结构中进行检验。最后,将该指数与其他测度传统空间集聚指数如全局和局部Moran指数及密度梯度估计进行对比.     

Roman agriculture in the conventus Bracaraugustanus (NW Iberia)

A review of archaeobotanical data, together with new, still unpublished data, from Roman sites in conventus Bracaraugustanus suggests the Romanization of the northwest Iberia brought little changes to the agricultural strategies of local communities in indigenous-type settlements. The main crops remain the same as in the Iron Age: Triticum aestivum/durum, Panicum miliaceum, Hordeum vulgare subsp. vulgare, Triticum turgidum subsp. dicoccum and T. aestivum subsp. spelta, Avena and Vicia faba. The first secure reference for the cultivation of Secale cereale in the region comes from a Roman context, suggesting that it was introduced in this period, although it probably remained a minor crop.
