The present study applies "Textual Patterns" like "general-specific" and "claim-counterclaim" to explore discourse coherence in Chinese students' English writing. The study confirms the function of the textual patterns as macro-structures for discourse interpretation and production, and proves textual patterns as effective tools in identifying and solving problems with discourse coherence in Chinese EFL (English as a Foreign Language) learners' writing. 展开更多

Multinational firms such as Apple Inc. have accomplished environmental colonialism in China through the transfer of ecological costs to the local environment. This paper discusses ambiguities in China's environmental legislation and supervision, Apple's business model, and "green washing. " Further, we have identified countermeasures such as the encouraging Environmental Non-Governmental Organizations (ENGOs), streamlining litigation procedures, increasing fines, and the development of nonprofit media organizations. 展开更多

The purpose of this research was to study learning retention in undergraduate biology students on the topic of enzyme properties by using simple enzyme activity from vegetables and fruits. A hands-on practical was developed to simplify detection of enzyme activity of amylase, protease and lipase on starch agar, dry whole milk agar, and trihutyrin agar, respectively. The subjects of the study were 24 senior undergraduates who studied in the Program of General Science, Faculty of Science, Srinakharinwirot University, Bangkok, in three semesters during 2007 - 2008. The basic concepts of enzymes, e.g., substrate specificity, how to detect enzymes and optimal enzyme conditions, were taught before the practical. The first enzyme, protease, was used in the second semester of 2007, and then changed to be lipase and protease in the first and second semesters of 2008, respectively. Ten open-ended questions were used to assess students in all semesters. In agreement with the constructivist learning model, it was demonstrated that students had learning retention and applied their prior knowledge to other enzyme experiments. 展开更多

In this paper,we consider unusual event detection problem in a novel viewpoint and provide an algorithm to solve the problem.The actions or events in the scene is usual or not will eventually be reflected on the changes of some basic features.We summarize these basic event features and propose special representation for each of them.Thus we can model these features in a uniform mode using adaptive Gaussian mixture model.Supervised and unsupervised unusual event detection algorithm can be designed to fit various situations based on this model.The superiority of our model is that it can detect unusual event automatically without to know the determinate model of unusual events.In conclusion,we provide two applications to verify the effectiveness of our model. 展开更多
