Visual media have dominated sensory communications for decades,and the resulting“visual hegemony”leads to the call for the“auditory return”in order to achieve a holistic balance in cultural acceptance.Romance of the Three Kingdoms,a classic literary work in China,has received significant attention and promotion from leading audio platforms.However,the commercialization of digital audio publishing faces unprecedented challenges due to the mismatch between the dissemination of long-form content on digital audio platforms and the current trend of short and fast information reception.Drawing on the Business Model Canvas Theory and taking Romance of the Three Kingdoms as the main focus of analysis,this paper argues that the construction of a business model for the audio publishing of classical books should start from three aspects:the user evaluation of digital audio platforms,the establishment of value propositions based on the“creative transformation and innovative development”principle,and the improvement of the audio publishing infrastructure to ensure the healthy operation and development of the digital audio platforms and consequently improve their current state of development and expand the boundaries of cultural heritage. 展开更多

As one of the Four Great Masterpieces of China,The Romance of the Three Kingdoms has become a landmark of ancient Chinese literature with vivid and profound character images,ups and downs of politics and war descriptions,and appealing historical plots.After being introduced to Japan in the second half of the 17th century,it was spread in Japanese society and was accepted for literary value,social needs and other reasons,then a series of evolutions were produced by combining with local culture,eventually becoming a national culture in Japan.This paper selects the most popular text of The Romance of the Three Kingdoms with 24 chapters and 120 verses in the Wanli period of the Ming Dynasty,and the Japanese translation of The Popular Romance of the Three Kingdoms published by Hunan Wenshan in 1689 as the objects,guided by Ralph Linton’s“Manifestation,Selection,Integration”cultural communication research method,to analyze the dissemination,acceptance and evolution of The Romance of the Three Kingdoms in 17-20 centuries’Japan,which started from the field of literature,then combined with various cultural forms and spread to the civic class,and finally entered politics area and produced a series of evolutions under the influence of Japanese values to become the representative culture of Japan.This paper suggests that in today’s world of frequent cultural exchanges,China should,based on strengthening cultural self-confidence,actively and appropriately select and accept foreign cultures with the attitude of prioritizing our own culture and utilizing foreign culture for our own purposes.The research outcome can provide experience for the current Chinese culture to go to the world with high quality. 展开更多

Here I present that organisms have two impor- tant properties, definite structure and self-reproduction. Based on the number and connection of the structural units, organisms can be di- vided into three groups, unicellular, particellular and polycellular organisms. It can be called polycellular evolution that organisms evolve from unicellular, particellular to polycellular. Also it can be called diploid evolution that organisms evolve from haplobes to diplobes, two groups based on the reproductive differences. Some concepts like spore, zygote and embryos are redefined in the paper. Moreover, I present that embryos are the most important boundary of bioevolution and organisms can be divided into two evolutionary phases, the lower and the higher. The lower organisms, Kingdom Microbia (kingd. nov.), are inembryonate, which include Acytophyla (phyl. nov.), bacteria, protozoa, fungi and inembryonate algae. The higher organisms are embryonate and have two branches, Kingdom Plantae and Kingdom Animalia. Plantae are sessile and, autotrophic or sporogenic, which include higher plants and Nudembryophyta (phyl. nov.). Animalia are heterotrophic and, motile or gametogenic, which include all multicellular animals. The new system, which reflects the two important phases of bioevolu- tion and two branches of higher organisms, can really correct the problem of different kingdoms in different researches or by different re- searchers. 展开更多

According to the research of Wen Jun and Li Peijia, this paper examins the articles and treatises regarding the English translations of Romance of the Three Kingdoms in China in the past five years. It is divided into four sections: Summary, Language, Literature and Culture. We point out the existing problems of the current studies;limited in traditional linguistic levels, leaning to the translation of Moss Roberts, neglecting the study of non-cover-to-cover translations, revelry at home and coldness abroad. Besides, we put forward the translation studies of Romance of the Three Kingdoms based on comparative literature to fill the gaps in the current research. The translation study of comparative literature pays attention to four aspects;literary translations and translated literature, cover-to-cover translations and non-cover-to-cover translations, C.H.

The research of General History of Chinese Science and Technology(GHCST) has so far failed to transcend the"positivist history", a program of historiography initiated by Joseph Needham. The historians after Needham have made important explorations on the historiographical reform of GHCST. However, nearly all of these explorations are still the methodological reflections of the positivist history perspective, failing to reflect metaphysically on such historiographical presuppositions as views of science, technology and history, which means they have failed to break away from the positivist history perspective. To go beyond the limitations of positivist history calls for the introduction of the perspective of phenomenology of body and reflecting on and criticizing the historiographical presuppositions of positivist history on a metaphysical level. Such reflection will lead us to a new program of historiography in the post-Needham era, that is"phenomenal history"or the GHCST from the perspective of the phenomenology of body. 展开更多

Since the end of the 20th century, Mo Yan has made an attempt to reflect on China's historical changes throughout the 20th century as a whole. Centered on such several novels as Big Breasts and Wide Hips, Life and Death Are Wearing Me Out and Frog, this paper explores the author's thinking of the interruption and repetition phenomena in China's 20th century history. Differing from viewing the history in a modem linear progressive perspective, Mo Yan regards the interruption of history as a sign of human degradation, which derives from the loss of folk history subjectivity. When history is treated rudely, its repetition will occur, and the one who treats history as laughingstocks will be written into history as part of a "farce". 展开更多

The Virginian: A Horseman of the Plains (1902) has been considered as one of the masterpieces of American western novels for its successful depiction of cowboys and local customs, which earns Owen Wister the Father of Western fiction. The paper aims to reveal the relationship between The Virginian and its historical context by applying the doctrines of New Historicism: historicity of texts and textuality of history. By historicity of texts, it points out that the work is the emblem of disappearance of western frontier, and it symbolizes the union of the Wild West and the civilized east. By textuality of history, it detects the change of social class, the development of livestock industry and railway, and their influence on the work at the later part of 19th century. 展开更多

Recent historiographic studies of cultural exchanges between Germany and Greece in the 19th and 20th centuries have tended to neglect the mutual influence of the two countries' intellectuals; as a result, there is insufficient appreciation of the extent to which historiography and philosophy were appropriated by the politics of the Interwar period. This article focuses on attempts by neo-Kantian philosophers to overcome the crisis of historicism, and on the impact of this crisis on Greek intellectuals' perceptions of historicism. The study shows that at the time historicism invoked the past to solve the problems of the present. My purpose is to show that in a time of crisis, Germany's pursuit of its Greekness in conformity with the Bildung tradition, and Greece's cultural dependence on Germany in the meaning-making of its own Greekness, shared common ground in the ideological uses of philosophy and history in the service of politics and the politics of culture. In the aftermath of WWI, German scholars raised the issue of the crisis of historicism. Neo-Kantian philosophers such as Heinrich Rickert, whose theory had a major impact on Greek intellectuals, became involved in this debate, posing the question of historical objectivity. Yet Rickert's philosophy of history soon fell into an impasse, leading to the rise of an idealist philosophy of history in the 1930s that committed itself anew to the dominant politics. In the 1930s, under the guise of idealism, Greek neo-Kantian intellectuals were claiming an objective historical narrative of the traumatic experience from 1922 onwards, which fit into the structure of an idealized ahistorical and mythic past, and which, as a hegemonic discourse, excluded its political enemies and propagandized the political struggle towards the fulfillment of the nation's historical and spiritual mission. 展开更多

Problems with clean water in coastal areas alongside an increase in population and community economic activities have diversified community activities.Coastal settlements bordering the high seas are characterized as arid areas with a lack of clean water.Here,the use of the range groundwater supply against seawater intrusion means that the water consumed by the community tastes salty and brackish.The availability of abundant seawater,processed through desalination technology,can be used to meet the daily clean water needs of coastal communities.Sustainable development goal(SDG)6 Water and Sanitation is concerned with ensuring that everyone has access to clean water and sanitation.In this regard,desalination technology is considered viable to achieve the SDGs in the environmental sector.Some countries have focused on using desalination technology to achieve target 6.4 by 2030.This goal aims to improve the efficiency of water use to reduce the number of people experiencing clean water scarcity by ensuring a sustainable supply of fresh water.The objective of this study is to examine the application of seawater desalination technology for clean water in the Kingdom of Saudi Arabia(KSA)and Indonesia,and identify the implications of desalination policies in these countries.Comparative studies were conducted using secondary data and literature studies on transforming seawater into clean water with technology.KSA applies seawater desalination technology to meet water needs.However,in Indonesia,policymaking has not holistically examined the potential of using seawater desalination technology for clean water.Until now,unlike in the KSA,Indonesia has not addressed the importance of the use of desalination technology in state policy. 展开更多

Two questions in the research of animal personality—whether there is a correlation between a personality trait and individual reproductive success,and what is the genetic basis underlying a personality trait—remain unresolved.We addressed these two questions in three shrub-nesting birds,the Azure-winged Magpie(Cyanopica cyanus,AM),White-collared Blackbird(Turdus albocinctus,WB),and Brown-cheeked Laughingthrush(Trochalopteron henrici,BL).The personality type of an individual was first identified according to its response to a territorial intruder.Then,we compared the fleeing distance,breeding parameters,and differential expressed genes(DEGs) in the brain transcriptome between bold and shy breeders.In the three species,bold breeders exhibited more aggressiveness towards an intruder of their territory than did shy breeders.The reproductive success of bold breeders was significantly higher than that of shy breeders in AM but not in WB and BL.The three species shared one DEG,crabp1,which was up-regulated in bold relative to in shy individuals.By regulating the expression of corticotropin-releasing hormone,higher crabp1 gene expression can decrease cellular response to retinoic acid.Therefore,bold individuals are insensitive to external stresses and able to exhibit more aggressiveness to intruders than their shier counterparts.Aggressiveness is beneficial to bold individuals in AM but not in WB and BL because the former could evoke neighbors to make the same response of defending against intruders but the latter could not.Although a personality trait may have the same genetic basis across species,its correlation with reproductive success depends largely on the life history style of a species. 展开更多

Biogeographical barriers to gene flow are central to plant phylogeography.In East Asia,plant distribution is greatly influenced by two phylogeographic breaks,the Mekong-Salween Divide and Tanaka-Kaiyong Line,however,few studies have investigated how these barriers affect the genetic diversity of species that are distributed across both.Here we used 14 microsatellite loci and four chloroplast DNA fragments to examine genetic diversity and distribution patterns of 49 populations of Populus rotundifolia,a species that spans both the Mekong-Salween Divide and the Tanaka-Kaiyong Line in southwestern China.Demographic and migration hypotheses were tested using coalescent-based approaches.Limited historical gene flow was observed between the western and eastern groups of P.rotundifolia,but substantial flow occurred across both the Mekong-Salween Divide and Tanaka-Kaiyong Line,manifesting in clear admixture and high genetic diversity in the central group.Wind-borne pollen and seeds may have facilitated the dispersal of P.rotundifolia following prevalent northwest winds in the spring.We also found that the Hengduan Mountains,where multiple genetic barriers were detected,acted on the whole as a barrier between the western and eastern groups of P.rotundifolia.Ecological niche modeling suggested that P.rotundifolia has undergone range expansion since the last glacial maximum,and demographic reconstruction indicated an earlier population expansion around 600 Ka.The phylogeographic pattern of P.rotundifolia reflects the interplay of biological traits,wind patterns,barriers,niche differentiation,and Quaternary climate history.This study emphasizes the need for multiple lines of evidence in understanding the Quaternary evolution of plants in topographically complex areas. 展开更多
