Review of Dactylosternum Wollaston, 1854 from China and Japan (Coleoptera, Hydrophilidae, Sphaeridiinae)

The species of the genus Dactylosternum Wollaston, 1854 occurring in China and Japan are reviewed. Ten species are recognized to occur in China, two of which were also recorded from Japan. Four new species are described from China: Dactylosternum nanlingensis Mai et Jia, sp. nov. (Guangdong, Jiangxi) from fungal hyphae on fallen wood, D. songxiaobini Mai et Jia, sp. nov. (Guangxi) from fallen wood with termites, D. pseudolatum Mai et Jia, sp. nov. (Guangdong, Hubei, Hunan, Jiangxi, Fujian, Hainan, Yunnan) and D. frater Mai et Jia, sp. nov. (Yunnan) from banana trees. Dactylosternum latum (Sharp, 1873) and D. salvazai Orchymont, 1925 are reported for the first time from China, and species recorded previously (D. abdominale (Fabricius, 1792), D. corbetti Balfour-Browne, 1942, D. hydrophiloides (MacLeay, 1825) and D. pui Jia, 2002) are redescribed or diagnosed. Dactylosternum abdominale (Fabricius, 1792) is confirmed to occur in Japan. Dactylosternum latum is only known from Japan based on type specimens believed to be collected in Nagasaki by G. Lewis in late 19th century; since the species was never re-collected in Japan later, its distribution in Japan seems doubtful. Dactylosternum vitalisi Orchymont, 1925 is synonymized with D. latum (Sharp, 1873), the variability of the latter species is discussed. We moreover found that the type series of D. vitalisi contains two species, with some paratypes actually belonging to D. pseudolatum Mai et Jia, sp. nov. All species of Dactylosternum living in China and Japan are diagnosed and illustrated and a key allowing their identification is provided. We infer that the compact antennal club and paralleled body form are characters related to the life inside of plant tissues, while loose antennal club and rounded body form is present in free living Dactylosternum species. The combination of characters for distinguishing Dactylosternum from other genera of Coelostomatini is also provided.

Does Economic Policy Uncertainty Affect Exchange Rate in China and Japan? Evidence from Threshold Cointegration with Asymmetric Adjustment

In this article, we estimate the links between nominal exchange rates (JPY/USD and CNY/USD) and economic policy uncertainty (EPU) in China and Japan by employing monthly data during the period span from January 1997 to September 2020. The threshold cointegration approach focus in TAR, M-TAR, C-TAR and C-MTAR is used. Results indicate the evidence of asymmetric effect in the adjustment process to equilibrium and the M-TAR is the best model to detect threshold effect for the (CNY/USD-CNYEPU) pair and the C-TAR is the best model to detect threshold effect for the (JPY/USD-JPYEPU) pair.

Media discourse in China and Japan on the COVID-19 pandemic: comparative analysis of the first three months

Purpose This study aims to analyze how English-language versions of e-newspapers in the first two countries affected, China and Japan, which are non-English-speaking countries and have different socio-economic and political settings, have highlighted Coronavirus disease 2019 (COVID-19) pandemic news and informed the global community. Design/methodology/approach A text-mining approach was used to explore experts’ thoughts as published by the two leading English-language newspapers in China and Japan from January to March 2020. This study analyzes the Opinion section, which mainly comprises editorial and the op-ed section. The current study groups all editorial discussions and highlights into ten major aspects, which cover health, economy, politics, culture and others. Findings Within the first three months, the media in both China and Japan shifted their focus from health and preparedness to the economy, politics and social welfare. Governance and social welfare were key concerns in China’s news media, while, in contrast, global politics received the highest level of attention from experts in Japan’s news media. Environment and technologies aspects did not receive much attention by the expert’s columns. Originality/value At the initial stage of a world crisis, how leading nations and initially affected nations deal with the problem, how media play their role and guide mass population with experts’ thoughts are highlighted here. The understanding developed in this study can provide guidance to news media in other countries in playing effective roles in the management of this health crisis and catastrophes.

Motif dan Kepentingan China dalam Pembentukan Regional Comprehensive Economic Partnership (RCEP)

The establishment of the Regional Comprehensive Economic Partnership (RCEP) began because of the conflict between China and Japan. The establishment of RCEP is to create the largest trade agreement in the world because this cooperation unites regional countries with large economies. China as a country that has the largest economic level among RCEP member countries makes China control most of the market in the region. This RCEP helps China in dealing with the trade war between China and the United States, although it has not yet had a big impact. This paper uses a qualitative method and focuses on China's motives in determining the RCEP. The results of this study confirm that China's motive in determining the RCEP is to counter-balance with the TPP and China's good image to Southeast Asian countries. In addition, RCEP has a significant impact on the Chinese economy.

Becoming Citizens in the Age of Online Social Networks

New media studies have attracted increasing scholarly attention as communication technologies become integrated into our everyday lives. New media provide unique contexts to share, record, and extend civic life and motivate civic commitment in the digital era. This chapter addresses the intersection of new media, culture, and political communication by exploring youths' civic engagement in China and Japan through individual voluntarism, civic participation, and political activism. It interrogates the civic use of social network sites in the digital age so as to increase our understanding of intercultural online interactions. Through the case studies of China and Japan, this research adds to the knowledge of intercultural communication in the networked society, with its potential to promote more democratic forms of engagement between citizens and states in the contexts of new media.

IoT Impact and Challenges on Robotic Waiters in Automation of Restaurants and Hotels

In China and Japan robots are used to serve in restaurants to serve or to just greet the customer. In restaurants robots need to understand the environment and make decisions accordingly, like changing the route if it finds any obstacle in between. To have this capability of making decisions and behaving like humans, robots need information from different sources from which they can understand the change in environment, position of other robots, and also the path to the destination. This can be done by integrating robots with IoT technology that allow the enhancement in the capabilities in robotic waiter. IoT also helps in monitoring the working parts of robots and movements. This chapter aims to discuss the real-time challenges and impact of IoT on robotics services in restaurants and hotels.
