Blixen-Finecke worldwide fame because the novel caused wide public concern among both critics and readers. The story unfolds a poetic picture which reveals the natural peace and harmony in Africa through the narrative angle of the heroine--Karen Blixen. In Out of Africa, the author, from multipoint viepoints, knits the legendary plot to display a picture of a community with the features of spiritual utopia, which is an ideal place for men to escape from the outside disturbance. The present paper, first, gives a brief introduction to the plot of the story. Then, it discusses the characteristics of spiritual utopian community on the African land from the following three perspectives： Karen Blixen is a pursuer to go after self-integrity so as to protect the harmony of spiritual utopian land in Africa; Africans are the paragons of self-integrity to pursue freedom on their homeland; and the western settlers are the dominators who have lost self-integrity in the spiritual utopian community because they have almost destroyed the ecological and social banlance on African land.展开更多

In this experiment twenty healthy male subjects were required to perform a driving simulator task for 3-hours. The physiological variables for evaluating driver mental fatigue were spectral values of blood pressure variability (BPV)including very low frequency (VLF), low frequency (LF),high frequency (HF). As a result, LF, HF and LF/HF showed high correlations with driver mental fatigue but not found in VLF. The findings represent a possible utility of BPV spectral analysis in quantitatively evaluating driver mental fatigue.展开更多
