Research on Improving Artistry of Exhibitions in History Museums in China

Chinese civilization,with its long and continuous history and rich cultural heritage,plays a central role in China’s dialogue with other civilizations.Therefore,it is necessary to collect and refine the defining symbols and best elements of Chinese culture and showcase them to the world;develop discourse and narrative systems with Chinese characteristics,better tell China’s stories,and make China’s voice heard.This effort can help Chinese civilization shine globally,interact with other civilizations,and promote its communication and influence worldwide.In China,history museums,as physical carriers of Chinese civilization,are an important component in developing Chinese discourse and narrative systems and an important channel to better tell China’s stories and make China’s voice heard.Improving the artistry of museum exhibitions caters to the public’s growing demand for a more enriching cultural experience and substantially promotes Chinese culture on a global scale.With the communication of Chinese civilization as the main focal point,this study investigated the current issues related to the artistry of history museum exhibitions in China and defined the artistry of history museum exhibitions and their connotations.Based on an in-depth analysis of the artistry of historical museum exhibitions within China,this paper enumerated the areas where improvements could be made to enhance exhibition artistry,intending to promote the communication of Chinese civilization.

Laboratory culture of the freshwater benthic gastropod Bellamya aeruginosa (Reeve) and its utility as a test species for sediment toxicity

This study aimed to develop original laboratory culture and sediment toxicity testing protocols for the freshwater gastropod Bellamya aeruginosa （Reeve）, a new potential species for sediment toxicity testing. B. aeruginosa was successfully cultured with an effective culture system under proposed laboratory conditions. Optimal ad libitum feeding levels for larvae, juveniles, and adults were 2.0, 6.0, and 16.0 mg fish food/（snall.day）, respectively. Mean survival rates of juveniles were higher than 90%, The snails could be sexed at 9 weeks of age, and their generation time is approximately 4 months. Reproduction continued all year around; the mean fecundity was 0.55 newborn/（female.day）. The utility of this species for bioassays was evaluated in both 10-day and 28-day case studies with artificial sediments. The 10-day LC50 of Cu for larvae was 480 μg/g dry weight （dw）, and the lowest observed effects concentration of Cu for survival and growth of larvae was 195 μg/g dw. Survival and growth are reliable indicators of acute toxicity. Larvae accumulated more Cu than adults. B. aeruginosa exhibited a higher sensitivity to Cu exposure than standard test species （Hyalella azteca and Chironomus tentans）. The 28-day test of sediment toxicity with adults showed that fecundity was a robust endpoint indicator of reproductive toxicity, and the biochemical endpoints of superoxide dismutase, catalase, and glutathione could be used as sensitive biomarkers for Cu-induced oxidative damage. B. aeruginosa can be therefore recommended as a candidate for the standardization of the freshwater sediment toxicity test protocol.

Innovative Design of Sustainable Landscapes Integrating People-oriented,History,and Ecology

Sustainable landscape is the only trend of future landscape development,it is of realistic significance to guide landscape architects to engage in sustainable landscape design.In this study,landscape design experience in recent years was summarized and analyzed by studying relevant design cases,then innovative design of sustainable landscapes integrating people-oriented,history and ecology was proposed to help landscape architects or beginners confused about the complex design techniques to figure out the design orientation.

On the Historical and Cultural Elements Implied in The Last of the Mohicans from the Perspective of Cross-Cultural Communication

The last of the Mohicans was written by American novelist James Fenimore Cooper in 1826,who is considered as the first long novelist of America.The work has no concentrate plots but the white people and the Indians'friendship,communication,and wars.The Last of the Mohicans was set in the mid-18th century when the French colonists and English colonists were fighting for Indian lands.English colonized America and were at loggerheads with France.It belongs to the frontier literature and creates a precedent for the American Frontier Fiction.The American western fiction has the most native feature.With the rise of multiculturalism trend at present,it is the best way for understanding the American local culture and history to study the American western fiction which is bred during the course of the frontier-running and Westward Movement.Cooper is a novelist who depicted the real and pure American life.Based on the frontier theme,he created Leatherstocking Tales,which is a series of five novels,are his masterpieces representing his style.Among them,The Last of the Mohicans prominently reflects the Indian culture.This thesis mainly explores the historical and cultural elements embodied in The Last of the Mohicans from the perspective of cross-cultural communication.
