Set in the New York upper class be-tween 1870 s and 1880 s, the novel depicts a touching love story. This paper analyzes the character traits of Newland Archer from afeminist perspective, and analyzes how his free love is suffocated by deep-rooted conventions, so as to illustrate the deadly influ-ence of patriarchy on people at that time. The New York upper class at that time dreaded scandal more than disease, and therefore,the true love between Newland Archer and Ellen Olenska fell victim to the patriarchal society. Archer is both the supporter and vic-tim of patriarchy. Ellen is a courageous new woman who longs for freedom and equality with men and thus is rejected by the NewYork upper class and makes great sacrifices. From the analysis, this thesis maintains that the oppressive patriarchy is exactly thedeep root of his unfortunate fate. This novel shows that women-consciousness of the West was burgeoning in the 20 thcentury, andconveys the author's wish of gender equality.展开更多
Population growth, trophic level, and some aspects of reproductive biology of two congeneric archer fish species, Toxotes chatareus and Toxotes jaculatrix, collected from Johor coastal waters, Malaysia, were studied. ...Population growth, trophic level, and some aspects of reproductive biology of two congeneric archer fish species, Toxotes chatareus and Toxotes jaculatrix, collected from Johor coastal waters, Malaysia, were studied. Growth pattern by length-weight relationship (W=aLb) for the sexes differed, and exhibited positive allometric growth (male, female and combined sexes of T. chatareus; female and combined sexes of T. jaculatrix) and isometric growth (male samples of T. jaculatrix only). Trophic levels of both species were analyzed based on 128 specimens. The results show that, in both species, crustaceans and insects were the most abundant prey items, and among crustaceans the red clawed crab Sesarma bidens and Formicidae family insects were the most represented taxa. The estimated mean trophic levels for T. chatareus and T. jaculatrix were 3.422±0.009 and 3.420±0.020, respectively, indicating that they are largely carnivores. Fecundity of T. chatareus ranged from 38 354 to 147 185 eggs for females with total length ranging from 14.5 to 22.5 cm and total body weight from 48.7 to 270.2 g, and T. jaculatrix 25 251 to 150 456 eggs for females with total length ranging from 12.2 to 23.0 cm and total body weight from 25.7 to 275.0 g. Differences in values of gonadosomatic and hepatosomatic indexes calculated for both species in this study may have resulted from uneven sample size ranges.展开更多

These myths were presented by the missionary and Sinologist William Frederick Mayers in The Chinese Reader＇s Manual： A Handbook of Biographical, Historical, Mythological and General Literary References （1874）, and other Chinese sources. Zeyer highlighted the first myth, which was connected with the Emperor Yao and showed Hou Yi shooting arrows at the nine suns appearing together in the heavens, and Lu Xun preferred the second myth, where the Archer Yi rebelled against the Emperor Tai Kang, whom he drove from the Capital, and later was killed by Han Zhuo. The myth of Chang E who flew to the moon is described only by Lu Xun.展开更多
