Based on our previously pulse-coupled integrate-and-fire neuron model in small world networks, we investigate the complex behavior of electroencephalographic (EEG)-like activities produced by such a model. We find EEG-like activities have obvious chaotic characteristics. We also analyze the complex behaviors of EEG-like signals,such as spectral analysis, reconstruction of the phase space, the correlation dimension, and so on. 展开更多

CR theory focuses on the study of academic or professional writing across different cultural settings. One recurring question of CR theory in the Chinese ESL context is whether the rhetorical differences in organization, modeling, and syntax between Chinese and English writing indeed exist, and if so how they affect ESL writing. Through examining the controversies surrounding these rhetorical differences along with a brief review of the development of CR theory and pedagogical implications, this paper contends that the study of CR theory has exerted beneficial influences on L2 writing. 展开更多
