Results: Of the 105 delirious medical inpatients, 48 (45.7%) had severe delirium, 41 (39.1%) developed less severe delirium while 16 (15.2) presented with no severe delirium. Sociodemographic characteristics found to be significantly associated with less to more severe delirium include male gender (P = 0.001), nonprofessionals (P = 0.003), income range of N20,000 - N49,000 (P Conclusion: This study demonstrates that delirium is often associated with higher severity in Accident and Emergency unit admission and there are strongly associated clinical characteristics to watch out for in high risk medical inpatients.

A Study of Chinese Students in the United States and Its Implication for English Teaching in China

Language acquisition is a system with four components： language development, academic development, cognitive development and sociocultural development. Based on this theory, Chinese students in the United States are studied from three perspectives： linguistically, culturally, and social psychologically. It indicated that, to help Chinese students develop their English performance and cultural appreciation in this diverse world, the profession of English teaching in China should cover a variety of domains, including linguistic, cultural and psychological input. Both American and Chinese education can benefit from this special group of Chinese students if they can be better understood, and used as a bridge between China and U. S. cultural and academic exchange. In the meantime, the mirror held up to the Chinese students in these perspectives reflects not only who they are but also who they can become.
