There are different possibilities to intersect when the distances between moving objects and the querying boundary are different.Therefore, moving objects have different influences to the query result. We set different deviation limits for different moving objects according to distances. A great number of unnecessary updates are reduced and the payload of the system is relieved.展开更多

Participants are 35 American undergraduates and 42 Chinese undergraduates respectively with the data eliciting technique--DCT (discourse completion test). Findings show that Chinese undergraduates tend to use different politeness strategies according to different social distance and social power while American undergraduates prefer to use positive politeness strategy most followed by negative politeness strategy, regardless of social distance and social power. The results of the study reveal cultural differences between the U.S. and China that lead to the distribution of diverse politeness strategies and also offer insights into what Chinese EFL learners are struggling with during their development of interlanguage pragmatic competence.展开更多

It is found that Chinese and American university students are significantly different in the choice of complaining strategies produced to professors, intimates, friends and strangers. The Chinese show greater respect to professors than Americans do. Generally, as to interlocutors with equal social status, Americans' complaining degree displays a gradually descending tendency along a social distance continuum, while the Chinese have intimates and strangers at the both ends, with friends in the middle. No significant difference has been revealed in the choice of complaining strategies to parents, but Americans tend to be more polite than the Chinese. This challenges Brown and Levinson's formula, Wx = D (S, H) + P (H, S) +Rx, which implies the same weight for each of these three factors. The study proves that in private conversations, the variable of social distance carries more importance than the variable of social status.展开更多
