However, the two heroines in these two plays, Nora Helmer and Lady Macbeth, demonstrate similar feminist qualities. By staging an overall contrastive analysis on the personality and tragic life of two protagonists from the perspective of feminism, it is founded that both of them are victims oppressed by the patriarchal system and they all have feminine consciousness against this system. Nevertheless, their distinctive complex personalities and different story settings make the reasons for their rebellion differ in many ways and they end up with different endings.展开更多

With abundant goods of sign values, conspicuous consumption, swelling-desire-stimulating power and the individuals' efforts to construct their identities through consumption as dominant features, consumer culture exerts negative and even devastating effects on the characters in the novel. Theories of ecocriticism shed new lights on the interpretation of consumerism reflected in the novel, especially on analyzing how the consumer culture makes the characters suffer from split personality, alienation from nature, society, and even from themselves and their spiritual ecology.展开更多

However, by using two narrative voic?es simultaneously in the novel, an intradiegeitic one and an extradeigetic one, Hawthorne actually reveals his equal disapproval of both the Pycheon siblings and Holgrave. In the intradiegetic narrative, the narrative voice as a whole takes its side with Holgrave and reveals Pycheon siblings'isolation from the united struggle of mankind. In the extradiegetic narrative where the narrator ad?dresses directly to his readers, the narrator expresses a similar disapproval of Holgrave, who is equally isolated from the chain of hu?manity for lacking sympathy for his fellow beings. With the co-existence of two narrative voices, Hawthorne's true concern lies in calling attention to the equally dangerous situations of isolation from the chain of humanity:an isolation from the chain of progress and that of human sympathy.展开更多

The study calculated the value of forest carbon stocks at a total of RMB 817.13 × 10^9 yuan in 2003 and RMB 839.93×10^9 yuan in 2008, with an average annual increase of 0.55 % from an increase in physical carbon sinks. The total value of forest carbon sinks in 2003 and 2008 was RMB 26.73×10^9 yuan and RMB 29.77×10^9 yuan, respectively, with an average annual growth of 2.18 %. From 2003 to 2008, both stock and flow value of forest carbon sinks increased, but the total net flow value of carbon sinks decreased. The growth rate for the environmentally adjusted Gross Domestic Product （eaGDP） for China＇s forest carbon sinks was 17.23 %, outstripping the average growth rate of 9.5 % for the GDP during the same period. The study alsoindicates that China＇s forest carbon sinks affects the GDP in the range of 0.25-0.26 %, and its economic potential is not relatively huge.展开更多

Research on carbon storage estimation of forest ecosystems has become a major research topic. However, carbon budgets of subtropical forest ecosystems have received little attention. Reports of soil carbon storage and topographic heterogeneity of carbon storage are limited. This study focused on the Jinggang Mountain National Nature Reserve as an example of a mid-subtropical forest and evaluated soil and vegetation carbon storage by field sampling combined with GIS, RS and GPS technology. We classified the forest into nine forest types using ALOS high-resolution remote sensing images. The evergreen broad-leaved forest has the largest area, occupying 26.5% of the total area, followed by coniferous and broad-leaved mixed forests and warm temperate coniferous forest, occupying 24.2 and 22.9%, respectively. The vegetation and soil carbon storage of the whole forest ecosystem were 1,692,344 and 5,514,707 t, with a carbon density of 7.4 and 24.2 kg/m^2, respectively, which suggests that the ecosystem has great carbon storage capacity. The topographic heterogeneity of the carbon storage was also analysed. The largest vegetation storage and soil storage is at 700–800 and 1000–1100 m, respectively. The vegetation carbon storage is highest in the southeast, south and southwest.展开更多

The study aimed at investigating and documenting indigenous knowledge （IK） on forage/fodder plant species and threats to their survival. Ninety-six in= formants between 20 and 80 years old were selected using prior informa- tion. Data were collected using semi-structured interview, guided field wail discussion and field observation. Preference ranking, Jaccard＇s coefficient of similarity and priority ranking were used for data analysis. One hundred twenty-six forage/fodder species of 90 genera and 43 fami- lies were collected in the study area. More than 88% of the species were reported with their vernacular names, where 68% were reported by the Afar Nation and 70% by the Oromo Nation. Family Poaceae was repre- sented by 25 species （20%）, followed by Fabaceae 18 （14%）. Preference ranking for the most preferred forage grasses as perceived by key informants revealed that Chrysopogon plumulosus was the most important forage/fodder species. Overgrazing was the major threat in the study area, scoring 22%.展开更多

Results show that mean seasonal survival was highest in green house （95.53%±2.33）, followed by homegardens （89.3%±1.89） and different canopy conditions （77.62%±6.73）; the highest values were found during February to April for both the homegardens （96%±1.68） and green house （98% ± 0.88） and lowest during November to January （78%±2.99） in homegardens and May to July （90%：t：4.53） in green house. In case of transplanted seedlings in different canopy conditions, mean seasonal survival was highest during May to July （98%±1.92） and lowest during August to October （66%±12.81）. However, mean seasonal growth of collar diameter was highest in different canopy conditions （23.99%±1.76） compared to green house （21.52%±2.70） and homegardens （12.44%±1.33） and it was highest during rainy season （May to July） and lowest during dry winter （November to January） in all the three experi- mental sites. These variations may be due to the different microclimatic conditions as well as nutrient status of the soil in all the three experimen- tal sites. Although, seedling quality plays a great role in their survival and growth, based on the result of green house experiment, it can be concluded that maintenance of seedlings in green house conditions during their early growth period may improve both the survival and growth for large scale plantation of the species. Thus, the species can be reintroduced in its natural forest range to compensate the loss of natural population of this precious species in northeast India.展开更多

They tend to pay more attention to the attractiveness of their "soft power",which includes values,life style , ideology and so forth. Just as Joseph S. Ny , the famous professor of Harvard who puts forward the concept of soft power, says ,"only by widespread communication and diffusion can a country reinforces its soft power". This is mass media's function. Since the 1990s, tens of thousands cultural products brought in from America are exported to foreign countries, including popular music, films ,TV programs, magazines, books and so forth. By making advantage of its monopoly position in media circle, the United States pursues cultural hegemonism and expands its popular culture all over the world. This thesis takes a general view of the great advantages of America multi-national media groups and how they push forward the American popular culture all over the world.展开更多

The proportion of respondents willing to pay （WTP） for protection of HNNR was 63 %. The WTP ratio was affected by geographical area, contact nature, personal preferences, and familiar degree of the respondents. The WTP value was affected by age, education level and career of the respondents. The mainly reasons for people rejecting to pay for protecting HNNR were ＂I am not familiar to HNNR＂ and ＂I had no capacity for additional spending because of low income＂. Weighted average individual WTP value was CNY 59.26 Yuan ind.^-1 year^-1 for all the respondents with WTP. The total non-use ecosystem service value of HNNR was CNY 1430 million Yuan in 2013. The heritage value was highest followed by existence value and option value. From the high ecosystem service value in HNNR, it is very important to construct nature reserve for protecting natural ecosystems and human sustainable use of natural resources.展开更多

The proportion of respondents willing to pay （WTP） for protection of HNNR was 63 %. The WTP ratio was affected by geographical area, contact nature, personal preferences, and familiar degree of the respondents.
