网站Web日志数据预处理模型的建立

文章对Web日志数据的预处理进行研究,建立了一个通用的基于Web日志数据预处理的模型.此模型主要包含数据清理、用户识别、会话识别、路径补充、格式化5个基本步骤.研究中,在用户识别步骤加入了时闻维度,基于此实现的算法在一定程度上提高了Web日志中用户识别的准确度.经过预处理之后,Web日志数据由原来的半结构化被转换成结构化,并存储在数据库中,以便后期Web挖掘的开展.实践证明,该模型是可行的,并具有良好的可扩展性.     

Business Incubators in China: A Financial Services Perspective

The business incubation industry in China has been booming since the mid-1990s. However, the lack of a well-developed financial services sector has become a major bottleneck to the growth of the industry. Based on our visits to 12 Chinese business incubators around the country and interviews with their executives, we present our perspective on the state of the incubator industry in China with special emphasis on incubators' financial services for their incubatees.     

Firm Resources and Corporate Venturing Investment

Corporate venturing (CV) in which established firms invest in new entrepreneurial businesses involves identifying opportunities and creating new combinations of resources to seize opportunities. Moving beyond literature that has focused predominantly on the consequences of CV, we adopt a resource‐based view to examine how knowledge‐based and organizational‐slack resources relate to the level of firm CV. The implications of the findings for future research are discussed. Copyright © 2011 ASAC. Published by John Wiley & Sons, Ltd.     

Individual Preferences for Trade Partners in Taiwan

This article investigates economic factors and non‐economic factors of individual attitudes toward free‐trade agreements with different countries. Based on the Stolper–Samuelson theorem, highly skilled workers in Taiwan should be more supportive of free trade with China and less supportive of free trade with the United States than should unskilled workers in Taiwan. Using survey data from Taiwan, we find that highly educated people in Taiwan are more supportive of free trade with both the United States and China, and the effects of education are much stronger with respect to free trade with China. We also find that individual risk attitudes, national identity, and ethnicity play important roles in explaining trade preferences.

固体颗粒稳定Pickering乳液的研究进展

固体颗粒代替乳化剂制备的乳液称为Pickering乳液。由于不含乳化剂且稳定性好,Pickering乳液可广泛应用于医药、农业、食品和化妆品等领域。现有研究表明,Pickering乳液的稳定性很大程度上取决于固体颗粒的性质,一般要求颗粒具有合适的尺度、几何形状和部分润湿性。因此,归纳总结了用于稳定Pickering乳液的固体颗粒的种类,包括无机颗粒、合成颗粒和天然有机化合物颗粒,重点描述了淀粉颗粒、蛋白颗粒和黄酮化合物颗粒在稳定Pickering乳液方面的研究。
