Energy internet zones (EIZ) supply multiple energy carriers to customers in certain regions. They can achieve high energy efficiency by energy cascade utilization. In mid‐term, they participate in the wholesale market and retail market simultaneously. Customers can shift their energy use among different hours and energy carriers to satisfy demand according to the retail prices. Unfortunately, multiple energy systems and markets bring various uncertainties on demand and prices. In this paper, the weekly bidding strategy for the EIZ is proposed to determine the optimal bilateral contracts to sign and the optimal energy retail prices. In retail market, the satisfaction degree and elasticity matrix describe customers' response. Distributionally robust optimization is adopted to consider the distributional uncertainties of random variables and Worst‐case Conditional Value‐at‐Risk is employed for risk management. The distributional uncertainties of pool prices and elasticity matrix are discussed in this paper. An EIZ in Shanghai, China is adopted to illustrate the proposed strategy. The results have great resistance to distributional uncertainties. The risk aversion and satisfaction degree affect the EIZ's strategy in wholesale market and retail market, respectively. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

Using real-time correction technology for typhoons, this paper discusses real-time correction for forecasting the track of four typhoons during 2009 and 2010 in Japan, Beijing, Guangzhou, and Shanghai. It was determined that the short-time forecast effect was better than the original objective mode. By selecting four types of integration schemes after multiple mode path integration for those four objective modes, the forecast effect of the multi-mode path integration is better, on average, than any single model. Moreover, multi-mode ensemble forecasting has obvious advantages during the initial 36h. [ABSTRACT FROM AUTHOR]

Accidental dispersal of Micronesian voyaging canoes is well known. While most of this occurred within the archipelagos, some was further afield. A twelfth century Japanese report narrates the arrival of a boat of castaways to the Izu Islands (off Tokyo). This paper examines this narrative against the background of other documented long distance dispersal from Micronesia, such as vagrant saltwater crocodiles and a canoe drifting from Lamotrek to Shanghai (China).

This paper examines a remarkable artifact of international business education, a four-book business Chinese language series published in Shanghai from 1916 to 1933 by a Japanese business school. Language-centered business education, they concluded, could break Japanese dependence on intermediaries and provide a significant competitive advantage over their western competitors. We carefully tabulate the main content of each chapter in this textbook series and draw on the theory of Situated Learning for our analysis. We find specific lessons in this historical content for teachers, business faculties, and government agencies currently tasked with improving today's international business programming with respect to the dynamic Chinese business environment.

This article investigates the thought on literary language that arose from the circulation of the New Sensationalist School in Japan, Shanghai, and Taiwan. Divided into three sections, it first examines Yokomitsu Riichi's modernist formal renovation, which was based on a rediscovery of the Chinese ideogram's physical and visual features. Situating this formal renovation in the literary Sinitic context (Kanbunmyaku 漢文脈) sheds light on Yokomitsu's ambition to build a modernist nationalist literary language. Second, this article analyzes the characteristics of the multilingual fragments in Liu Na'ou's works and suggests three possible explanations for his linguistic style. This article also points out that Liu's linguistic diversity might be criticized for being a kind of comprador literature, which, consciously or not, imported the colonial or orientalist gaze inherent in foreign literary texts. Third, this article focuses on Weng Nao, a Taiwanese New Sensationalist writer working in Japanese, and highlights how his eclecticist writing strategy championed archetypically Taiwanese subjects while allowing the form to parallel those of his Japanese counterparts. In the conclusion, we discuss the hybridity of the literary languages of Yokomitsu, Liu Na'ou, and Weng Nao, and some possible ways to reflect upon written language (bun/wen) in the Sinosphere (Kanjibunkaken/Hanjiwenhuaquan).

The 1932 Sino-Japanese conflict in Shanghai was the first example of a modern war waged in a large city between two heavily equipped armies. It was also the first urban conflict during which massive destruction, especially aerial bombing, ensued with utmost disregard for the consequences to civilians. This paper looks at the damage and losses the two contending armies suffered. The group of Chinese armies involved in the conflict was not prepared either to handle the consequences of using highly lethal weapons or to provide the appropriate level of medical assistance to their soldiers involved. The result was a catastrophic level of casualties. The battle for Shanghai announced the frightening massive waves of destruction that World War II would unleash on European and Japanese cities.

It is widely acknowledged that discursive practice in classrooms plays a key role in student learning of mathematics. This study extends a previous study on spoken mathematics (Clarke and Xu in ZDM Int J Math Educ 40(6):963-981, ) and seeks to compare the discursive practices in classrooms from Seoul, Shanghai and Tokyo with a particular focus on meta-discursive rules (Sfard in Educ Stud Math 46:13-57, ; Sfard in Thinking as communicating: human development, the growth of discourses, and mathematizing, Cambridge University Press, Cambridge, ) that regulate exchanges between the teacher and students. The analysis centres on the events when the topic of 'linear equations' was introduced. The similarities and differences of the three classrooms suggest that while the shared macrocultural values and beliefs may frame the social activity of the classrooms in similar ways, the meta-discursive rules of classroom microculture determine the opportunities for student learning in mathematics.

The impact of the recession on global markets motivates us to explore the effect of the stock market on the economic stability of a country. The growth of a stock market depends on various factors such as inter-dependency, globalization, economic policies etc. In this paper, we apply the recently developed multifractal detrended partial cross-correlation analysis method on some Asian markets by assuming NASDAQ composite index commonly influences these markets. For this purpose, we analyze the daily returns of three Asian markets such as China's Shanghai composite index (SHCOMP), Japan's Nikkei stock average index (NIKKEI 225), and India's Bombay stock exchange (BSE) sensex index over a period of 18 years (2000–2018). The analysis was performed between all bivariate time series after removing the external influence factor and the results indicate that there exists long-range partial cross-correlation behavior and multifractal nature. For comparison, we also performed analysis without removal of external influence factor i.e. multifractal detrended cross-correlation analysis. From the calculated Hurst scaling exponents, we found that the NASDAQ composite index shows significant influence on these analyzed Asian stock markets. • We have studied the partial cross-correlation on some Asian stock markets. • The MF-DPXA method was used to identify the influence of common external factor. • The partial cross-correlation coefficient quantifies the intrinsic cross-correlation. • We found the existence of multifractal nature in all bivariate time series analysis.

Understanding the work values of the current and future workforce is essential for designing a human resource management system that attracts, motivates, and retains talent. This study provides an updated, in-depth analysis of the work values of the next generation of business leaders in the commercial centers of China, Japan, and Korea. Although previous research has often clustered these countries together and labeled them Confucian Asia, survey results from more than 700 respondents reveal striking differences in work values across countries. The Chinese are more individualistic and career oriented, whereas the Japanese are more risk averse and work oriented, and the Koreans are often somewhere in-between. We argue that the value differences can be largely explained by different economic influences in these three countries. This study enhances our understanding of crossvergence theory by distinguishing economic influence in the economic development stage, economic growth, and inward foreign direct investments. While these economic indicators might be related, their influences on work values could be conflicting. The findings suggest that that each economic indicator has a unique effect on the development of work values. [ABSTRACT FROM AUTHOR]

On the basis of a generalized interdisciplinary method that consists of a modification of Hamilton–Ostrogradski principle by expanding the Lagrange function with two components that address the functions of dissipation energy and the energy of external conservative forces, a mathematical model is presented of an electromechanical system that consists of the force section of a magneto-levitation non-contact maglev suspension in a prototype traction vehicle. The assumption that magnetic potential hole, generated naturally by means of cryogenic equipment, is present in the levitation suspension, serving to develop the model system. Contrary to other types of magnetic cushion train suspensions, for instance, maglev–Shanghai or Japan–maglev, this suspension does not need a complicated control system, and levitation is possible starting from zero train velocity. As high-temperature superconductivity can be generated, the analysis of levitation systems, including the effect of magnetic potential holes, has become topical. On the basis of the model of a prototype maglev train, dynamic processes are analyzed in the levitation system, including the effect of the magnetic potential hole. A system of ordinary differential equations of the dynamic state is presented in the normal Cauchy form, which allows for their direct integration by both explicit and implicit numerical methods. Here, the results of the computer simulations are shown as figures, which are analyzed. [ABSTRACT FROM AUTHOR]
