A Geohistorical Study of ‘The Rise of Modern Science’: Mapping Scientific Practice Through Urban Networks, 1500–1900

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the ‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of knowledge that relate to, but do not mirror, material changes in the system.

基于机器学习的Web链接的抽取

互联网网页是通过超链接连接起来的,为人们的日常生活和商务用途提供了非常丰富的信息资源。链接结构分析在万维网的很多研究领域发挥着越来越重要的作用。然而存在着许多与主题无关的链接,造成了主题漂移。本文分析了链接本身的特点,介绍了一种有监督机器学习方法自动地抽取网页中的相关链接。试验结果表明该算法具有实用的价值。

Intercultural contacts and acculturation resources among International students in Australia: A mixed-methods study

This paper explores the impact of acculturation conditions, orientations and outcomes on international students in Australia’s tertiary education sector. Specifically, we investigate the factors that facilitate or hinder acculturation of international students within a multidimensional acculturation context (Arends-Tóth & van de Vijver, 2006). We used a sequential exploratory mixed-methods design in two studies to investigate acculturation of international students at an Australian university and test how these factors are related to psychological and sociocultural outcomes. In Study 1, we conducted a generic qualitative study using semi-structured interviews with a conventional content analyses approach,which compared the experiences of international students who on average had high numbers of positive experiences versus those who had high numbers of negative experiences. We found that a support network of mixed-nationals, and especially host locals, facilitates positive psychological and sociocultural adjustment, and buffers acculturative stress. Study 2 quantitatively tested the association of factors found in Study 1 (perceived stereotypes, intercultural and ethnic network/resources) with psychological and sociocultural acculturation outcomes. Study 2, shows that perceived negative stereotypes loosen ties with the dominant (host) culture and reinforces ties with the ethnic (non-host) culture. The social resources associated with either culture was found to be useful for acculturation, with both independently contributing to participant well-being. Contact with host locals played a particularly crucial role in developing these resources. Our findings provide foundations for pragmatic policy implications, suggesting value in the development of formally organized contact programs in the early sojourn experience of international students.

Android平台下恶意软件分析与检测

针对Android平台下恶意软件侵扰问题,提出一种基于权限—敏感API特征的加权朴素贝叶斯分类算法的检测方案。首先对Android应用程序中的配置文件进行解析,然后利用Apktool工具对APK文件进行反编译,提取出权限—敏感API特征集,并通过信息增益算法和卡方检验算法过滤冗余数据,最后利用加权朴素贝叶斯分类算法的恶意软件检测模型进行分类判断。实验结果证明,该系统能有效提高分类器的效率和恶意软件的检测率。
