Social Networks | China Biographical Database Project (CBDB) Social network analysis (SNA) provides an alternative to the factor-based approach in L. Stone's discussion of prosopography. Charles Wetherell writes: “Conceptualizing community as collections of personal relationships … provides historians with a blueprint for evaluating when, how and why people in the past used kin and non-kin in the course of their lives. The findings of social network analysts that people need and seek emotional and economic support of different kinds, from different kinds of people, suggest new analytical imperatives. It is not enough now to look solely at how people used kin in times of crisis. All social network queries in the stand-alone version of CBDB export data for visualization and some analysis to Pajek, freeware for social network analysis for Windows in UTF-8, GBK, or Pinyin romanization. An example of network visualization is a set of 2717 letters by 453 persons sent from and to leading Neo-Confucians of Zhu Xi’s generation

Close to 5000 collections of poetry and other writings by individual women are recorded for the Ming and Qing periods. However, less than a quarter of these materials have survived the ravages of history, and these have mostly ended up in rare book archives in libraries in China that are difficult to access. The Ming Qing Women's Writings digital archive and database project is dedicated to the digitization of collections of writings by women in late imperial China (1368-1911). The Drs.

Sistema de información geográfica En la imagen capas raster y vectoriales en el SIG de código libre QGIS. Un ejemplo de uso de la superposición de capas en una aplicación SIG. En este ejemplo la capa de la cubierta forestal (en verde) ubicada en la parte inferior, se encuentra superpuesta por la capa topográfica conformada por las curvas de nivel y por las capas de la red hidrográfica y los límites político administrativos. En los SIG la superposición topólogica crea nuevas capas de información requeridas para obtener una visualización correcta del mapa final. En el sentido más estricto, es cualquier sistema de información capaz de integrar, almacenar, editar, analizar, compartir y mostrar la información geográficamente referenciada. Por otro lado, un sistema de información geográfica puede ser concebido como un modelo que representa el mundo real. Funcionamiento de un SIG[editar] Un SIG puede mostrar la información en capas temáticas para realizar análisis multicriterio complejos. Historia de su desarrollo[editar] Puntos
