Since the 1970s, a continuous exchange of information about conservation between Europe and East Asia has greatly influenced approaches to the treatment of paper objects as well as the tools and materials used. This knowledge is often disseminated and absorbed in a purely practical manner, stripped out of its wider cultural context. However, what is considered 'appropriate' treatment is closely linked to how a particular culture has historically interacted with artworks and arguably the lack of broader cultural perspectives can lead to misguided assumptions in the evaluation of those practices. This article reflects on the differences between European and East Asian cultures of paper conservation. By taking into consideration the relevant cultural, philosophical and historical contexts, the article aims to explore how approaches to conservation, as well as to the profession itself, have developed in these two different parts of the world. It further encourages paper conservators to reflect on their own training and practices while offering an understanding of how these approaches can sometimes be mutually exclusive.

Paper City (2021), directed by Adrian Francis, is a documentary film that highlights the 70th anniversary of the firebombing of Tokyo on March 10, 1945. The film presents three elderly survivors' oral accounts of the firebombing and observes their work as memory activists in a long campaign to compel the Japanese government to publicly memorialize the event in a way commensurate with its enormous devastation. Reflecting on issues of memory and forgetting, Francis intends the film as a way of passing survivors' experiences to audiences, who can help to transfer memory to others and to generations beyond.

This paper examines how geography matters for the location of industries in East Asia, employing regression analyses on a novel and comprehensive regional GDP dataset. This study examines how geography affects industrial location patterns, particularly the role of infrastructure, such as ports and airports. This paper analyzes the current economic geography of East Asia using the novel dataset. The regression analyses utilize location quotients as the dependent variable and incorporate explanatory variables, such as domestic/foreign market access, per capita income, population density, and distance-based dummies for ports and airports. The findings reveal that the determinants of industrial location differ significantly across industries. The relative importance of domestic versus foreign market access and proximity to ports and airports varies across sectors. The results imply that countries/regions cannot easily host industries of their choice, as different industries require distinct locational characteristics. [ABSTRACT FROM AUTHOR]

Just as they are to the events themselves, the Opening Ceremonies of the Olympics have become central to academic research on the Games and their political, social, and cultural roles. And so the recent string of Olympic Games held in East Asia – two of them under the shadow of the COVID-19 pandemic – offer the opportunity to think both about region-specific meanings associated with these highly scripted affairs and about the ways they might destabilize broader judgments about the Olympics and their implications. This paper introduces the contributions to this special volume on the Opening Ceremonies at Asia's recent Olympic Games, aiming to draw attention not only to the specific contributions of each paper but also to the themes that they collectively engage.

The height of the F2 peak electron density (hmF2) is an essential parameter in studying ionospheric electrodynamics and high-frequency wireless communication. Based on ionosphere ray propagation theory, the physical relationship between M3000F2 and hmF2 is derived and visualized. Furthermore, based on the above physical theory and the machine learning method, this paper proposes a new model for determining hmF2 using propagation factor at a distance of 3000 km from the ionospheric F2 layer, time, and season. This proposed model is easy to understand and has the characteristics of clear principles, simple structure, and easy application. Furthermore, we used six stations in east Asia to verify this model and compare it with the other three models of the International Reference Ionosphere (IRI) model. The results show that the proposed model (PRO) has minor error and higher accuracy. Specifically the RMSE of the BSE, AMTB, SHU, and the PRO models were 20.35 km, 31.51 km, 13.59 km, and 5.68 km, respectively, and the RRMSE of the BSE, AMTB, SHU, and PRO models were 8.17%, 11.88%, 4.96%, and 2.12%, respectively. In addition, the experimental results show that the PRO model can better predict the trend of the hmF2 inflection point. This method can be further extended to add data sources and provide new ideas for studying the hmF2 over global regions. [ABSTRACT FROM AUTHOR]

In the latest issue's "Editor's Note" of EASTS, Wen-hua Kuo made a call to East Asian science studies scholars to commit to an archeology of the social and technical infrastructure of epidemics. Coincidently, ten historians and sociologists working on science, technology, medicine, and environment with a focus on China, Japan, Taiwan, Singapore, and South Korea had just begun a collective effort to understand how face masks had become the most important part of the current pandemic governance in East Asia. As its first step, a virtual workshop, "The Socio-Material History of Masked Societies in East Asia," was held at the Max-Planck Institute for the History of Science on 26 October 2020. This forum aims to introduce the virtual meeting's outcome to the wider EASTS community and encourages them to engage with the collaborative enterprise to investigate the history of masks. All papers focus on the socio-material dimension of masks while problematizing current culturalist explanatory narratives about "masked societies" in East Asia. By doing so, the papers show how mask use is closely linked to heterogenous but interconnected entanglements of environmental governance, political movements, and risk cultures in East Asian polities. It interrogates these relationships in the context of scientific controversies and quarantine regimes. [ABSTRACT FROM AUTHOR]

The issue of Western, Educated, Industrialized, Rich, and Democratic (WEIRD) samples dominating research has been ongoing for decades, and now the emerging trend is to turn to theoretical perspectives from the Majority World. Adopting Western-centric methods based on reductionism can overlook important details and differences between similar cultures, particularly in East Asian cultures, where the Confucian values of relational harmony take many forms. We discuss a novel theoretical perspective on moral constitutions in Confucian heritage cultures. Our central tenet is that divergent moral concepts and ideals are present in Confucian cultures because each culture emphasizes a specific pillar and the self is situated differently in the social relationships that define the scope of interpersonal moral obligations. We consider three Confucian countries: China, Japan, and South Korea as examples. Despite geographical proximity and conventional categorization in cultural psychology, each Confucian country manifests distinct patterns of the self, moral ideals, and behavior in socio-moral contexts. To understand how and why moral worldviews vary within a region, we need to examine how the self in socio-cultural contexts differs and guides interpersonal norms and behaviors across sociocultural contexts. We conclude this paper by offering methodological recommendations for including indigenous moral concepts outside the WEIRD context. [ABSTRACT FROM AUTHOR]

Introduction: Although there have been qualitative meta-syntheses on experiences of eating disorders treatments, there is a paucity of syntheses specifically examining the perspectives and experiences of eating disorders treatments (ED) in East Asia (EA). Such synthesis could facilitate a better understanding of culture-specific perspectives and experiences. This review complements a quantitative scoping review published on ED treatments in EA (Yim & Schmidt, 2023), where most interventions reviewed focused on cognitive behavioural therapy (CBT) and internet interventions. The present meta-synthesis summarises stakeholders' views on treatments and to synthesise clinical and research recommendations. Method: A systematic search of five databases and a citation search were conducted to identify relevant studies and data were analysed using thematic synthesis. Out of the 301 studies found, a total of 12 papers were included in the analysis. Results: A diverse range of treatments, such as family therapy, paediatric/psychiatric inpatient care, CBT, and counselling, were discussed. Three overarching themes were identified: Delineating Physical and Psychological Recovery; 'I am not alone in this battle'; and Barriers to Change. The themes further delve into the various obstacles to recovery, including financial concerns and limited access to professionals and services. Culture-specific factors include family obligations and promoting family harmony. Balancing interdependence and independence from one's family, as well as understanding family body ideals versus broader societal body ideals, are important considerations in ED interventions. Discussion: Some themes paralleled other qualitative syntheses, highlighting improved family relationships, perceived authoritarianism in treatments, and financial barriers. The review extends beyond the previous findings, revealing nuanced factors like family roles, cultural values, and norms. Clinical recommendations include incorporating family context in treatment and considering cultural influences on body image ideals. Capacity building through telemedicine and increased training is essential for advancing ED treatment in East Asia. Continued research is needed to better understand and treat people affected by ED in EA. Plain English Summary: Research on eating disorders (EDs) treatment mainly focuses on Western countries, with little exploration of experiences in East Asia. To fill this gap, we reviewed 12 studies on the perspectives of individuals, families and clinicians regarding EDs treatments in East Asia. Our synthesis identified three main themes: Physical and Psychological Recovery: Effective treatment needs to address both physical and mental aspects of recovery. Finding Support – 'I am not alone in this battle': Many individuals find strength in knowing they are not alone. Barriers to Change: Obstacles like financial difficulties, limited EDs knowledge from professionals, and cultural factors can hinder recovery. Cultural-specific factors such as family obligations and maintaining family harmony can impact on treatment motivation and effectiveness. Balancing family's wishes/ interdependence and personal aspirations/ independence can also be a challenge. Our findings highlight the need for culturally sensitive treatments. Expanding telemedicine and increasing provider training can also help overcome treatment barriers. In conclusion, understanding cultural and contextual factors is essential for developing effective support systems and improving ED treatment outcomes in East Asia. [ABSTRACT FROM AUTHOR]

This paper offers a Bourdieusian field analysis to unpack the intersection among sexuality, place, and mobility through an ethnographic study of Taiwanese gay men's trips to Bangkok. It unveils that how the societal cause of 'Eastern orientation'— a racialised sexual desire for 'white Asians' among Thai gay men — and other material circumstances have transformed distinct scales of territory, including nation-states and gay establishments, into nuanced yet not thoroughly disparate sexual fields. Such nuances are closely associated with gay men's intra-Asian mobility between Thailand and Taiwan that I elucidate through the concept of 'sexuality on the move.' This concept suggests that individuals' geographical movements may diversify their sexual habitus as well as fluctuate their tiers of desirability and vice versa, delineating how different aspects of human sexuality are reshaping and reshaped during or after their embodied mobility. At the same time, their yearning for sexuality alterations also shapes the pattern of individuals' trans-national and intra-urban movements. Moreover, the paper underscores that these alterations are not just objective reality but these gay men's subjective belief which, along with their sexual desire, embodied practices and personal experiences composing a conceptual 'circuit of sex and tourism', attracting and captivating gay men to participate in and then be obsessed with this form of sexual/touristic practice.

In current times that emphasize active aging, older adults are often encouraged to participate in interest classes at community centers. Adopting an ethnographic research approach to understand the subjectivities of older mothers, this paper not only sees community centers as a space for older adults for taking interest classes, but also as an infrastructure that defines relationship values. This paper examines the motivations of older mothers in urban Taiwan who have established a routine at a community center. By emphasizing the public space, that is, the values indoctrinated at the community centers, this paper investigates how community center activities offer self-care practices for older women, and how these women embody motherhood by taking care of themselves. This paper expands the notion of motherhood by investigating the subjectivities of older mothers as well as the effects of the global aging discourse on them. This study of urban Taiwan sheds light on understanding the subjectivity of aging mothers in other East Asian cities. The data of this paper were collected through participant observations at community centers, in-depth interviews, and analysis of newspaper archives. [ABSTRACT FROM AUTHOR]

The ratio of the total electron content (TEC) to the F2-layer peak electron density (NmF2) is known as the ionospheric equivalent slab thickness (EST, also known as τ), and it is a crucial indicator of the ionosphere. Using TEC and NmF2 data from the years 2010 to 2017, this work conducts a comprehensive statistical analysis of the ionospheric slab thickness in Beijing, which is in the midlatitude of East Asia. The outcomes show that the τ have different diurnal variations at different seasons for high/low-solar-activity years. On the whole, daytime τ significantly greater than nighttime τ in summer, and it is the opposite for the τ in winter regardless of the solar cycle, whereas the τ during equinox shows different morphology for high/low-solar-activity years. Specifically, daytime τ is larger than nighttime τ during equinox in years of high-solar activity, while the opposite situation applies for the τ during equinox in years of low-solar activity. Moreover, the pre-sunrise and post-sunset peaks are most pronounced during winter for low-solar-activity years. In summer, there is a great increase in τ during the morning hours when compared with other seasons. Furthermore, the τ decreases with the solar activity during nighttime, whereas it seems there is no correlation between daytime τ and solar activity. This paper explained the primary diurnal variations in τ across different seasons during high-/low-solar-activity years by analyzing relative fluctuations of TEC and NmF2 throughout the corresponding period. In addition, based on the disturbance index (DI), which is calculated by instantaneous τ and its corresponding median, this paper found that the storm-time τ might increase when compared with its median value during the daytime, while it may both increase and decrease during the nighttime, especially around dawn and dusk hours. To further analyze the physical mechanism, an example on 2 October 2013 is also presented. The results indicate that the positive disturbance of τ during the main phase of a geomagnetic storm might be caused by the prompt penetration electric field and neutral wind during the storm, and the τ increases during the early recovery phase might be due to the disturbance dynamo electric field as well as the neutral wind during the storm. Moreover, there is a negative disturbance of τ in the recovery phase during the most disturbed sunrise hours, and it might be due to the electric field reversal, neutral wind or other factors during this period. This paper notes the differences of τ in midlatitude between different longitudinal sectors from the related climatology and storm-time behavior, as it would be helpful to improve the current understanding of τ at midlatitudes in East Asia.

This paper compares the exchange of Ming porcelain between Ming China and Joseon in comparison with those exchanges between Ming and other countries in East Asia in order to bring out similarities and differences and highlight the complexity and dynamics of East Asian cultural exchanges. First, the similarities are that the times when the Ming court bestowed porcelain on other countries were concentrated in the first half of the fifteenth century in most of the Asian region. Within the framework of tribute trade, porcelain with a three-clawed dragon design was found in large quantities. During similar periods of time, Longquan celadon and Jingdezhen blue and white porcelain as well as private kiln porcelain wares increased and had common features. Second, what makes the exchange with Joseon distinctive is the introduction of porcelain overland by Ming envoys whose country of origin was Joseon and the shipment of table ware sets manufactured by Ming imperial kilns. Also, most of the Ming porcelain discovered in Joseon has been Jingdezhen blue and white porcelain which was common with other East Asian countries, but only a few discoveries of Longquan or Zhangzhou wares, nor was there much Kraak ware from Jingdezhen kilns or Southeast Asian celadons. These differences put Joseon in a unique position. This analysis provides an implication that diplomatic interactions and the changes in distribution brought about by the main trading forces should be considered in order to have a deep understanding of porcelain exchange between Ming China and Joseon and throughout East Asia.

Using multiple observational and reanalysis data, this paper investigates the impact of the interdecadal shift in summer Arctic Oscillation (AO) on precipitation in East Asia, by removing ENSO influences. The results indicate that the lower-layer activity center of summer AO in Atlantic shifted eastward after the mid-1980s. This regime shift of summer AO has a significant impact on precipitation in East Asia. Before the mid-1980s, the key regions in which precipitation was affected by AO in East Asia were northern East Asia and Northeastern China and adjacent regions. After the mid-1980s, the key regions in which precipitation was affected by AO in East Asia were central Inner Mongolia and Southern China. The mechanism of precipitation changes can be attributed to changes in atmospheric circulation and water vapor transport related to AO changes. After the mid-1980s, the influence of AO on geopotential height over northern East Asia weakened; meanwhile, the impact of AO on geopotential height over China increased. Consistent with the changes in atmospheric circulation, water vapor transport in East Asia also underwent interdecadal changes before and after the mid-1980s. The differences in atmospheric circulation and water vapor transport in East Asia can be traced back to the North Atlantic. Before the mid-1980s, wave activity flux related to summer AO tended to propagate in high latitudes and subtropics; after the mid-1980s, the wave activity flux changed in its subtropical path and propagated eastward from the North Atlantic through the Middle East to China, significantly affecting the summer precipitation in China.

Using a sample of East Asian banks covering the period 1999–2014, this paper analyses the impact of natural disasters on commercial bank performance and how financial integration moderates this relationship. A dynamic GMM model reveals that natural disasters significantly lower deposit ratios but have no contemporaneous relationship with liquidity, credit risk, profitability and default risk. There is also evidence of a lagged effect of disasters, increasing deposits and lowering liquidity one year after the event. Furthermore, foreign banking claims, specifically those extended by regional Asian lenders, help to alleviate the deposits decline in the aftermath of natural disasters. These baseline findings are mainly driven by severely affected countries. Overall, the paper highlights the role of commercial bank deposits and foreign banking claims as sources of finance for post-disaster recovery. In particular, the resilience of Asian foreign claims in the event of natural disasters provides evidence to support intra-regional financial integration in East Asia. [ABSTRACT FROM AUTHOR]

In this paper, we explore the relationship between regional powers and security norms by examining the influence of the liberal international order (LIO) on regional security dynamics in East Asia. In examining the influence of the LIO on East Asian nonproliferation norms, the USA and its partner nations have displayed a great deal of inconsistency regarding nuclear nonproliferation. We contend that this inconsistency offers opportunities for regional powers like China to reinforce or contest expectations associated with international nuclear norms. Often perceived as a stable pillar of the international order, variations in nuclear nonproliferation norms from the global to those in East Asia suggest a need to reconsider the influence and nature of the ILO on regional orders more broadly. Due to the role regional powers play in this relationship between the global and regional levels, this research also reinforces the continued importance of the Regional Powers Research Program.

This special issue, entitled "Paleolimnology and Paleoecology in a Rapidly Changing Asia," was initiated during the third China Workshop on Lake Paleoecology that was held in Kunming, China, in December, 2019. Here, we summarize some of the key findings from the 10 papers that are included in this issue. The papers present sediment surveys of lakes from different parts of East Asia, and studies that spanned a variety of timescales, through multi-proxy analyses of modern samples, short cores and Holocene records. Overall, this special issue provides an up-to-date research snapshot in the fields of paleolimnology and paleoecology from rapidly changing regions of Asia, with a focus on the sediment signals of lake development, ecological shifts and anthropogenic forcing in the context of continuing climatic and societal changes.

Most Asian countries are regarded as Confucian countries although each has its own historical and cultural background. Little is known about how people in different Asian countries perceive their family boundaries. This study is an attempt to compare the perception of the family in China, Japan, and Korea. We examined the family perception and found substantial differences among the three. Chinese people showed the widest and paternally extended perception of family. Data from people in Korea nearly matched data from China, but family perception developed bilaterally. People in Japan, however, perceived only blood‐tied, intimate relations as family members. In addition, the perception of the family was not substantially different between the genders in Japan and China, but in South Korea, men perceived family boundaries more widely than women, implying that women have a greater family burden than men in Korea. Considering the heterogeneity in family perceptions in these countries, this paper tries to explain how social institutions interact with individuals and impact the perception of family. Finally, this paper concludes that it is inappropriate to tie the three East Asian countries as 'Confucian civilizations' in terms of family perception. [ABSTRACT FROM AUTHOR]

This paper introduces a relatively novel theoretical approach to investigate cross border student mobilities in East Asia, a region growing in importance as a provider of international education. It does so by bringing Sara Ahmad's writings on the sociality of emotions, with Jacques Derrida's analyses of hospitality, We draw on empirical data from a cross national study to explore the emotions that shape student decisions to choose East Asian study destinations. By problematising the gift of the scholarship, using Derridean understandings of hospitality, we reveal the limits of contemporary forms of international education. Reflecting on histories of Asia-focused student mobilities, the paper highlights the entanglements of hostility and hospitality, and the inseparability of hosts and guests. It is this realisation that will enable ethical, non-exploitative forms of education. [ABSTRACT FROM AUTHOR]

This paper aims to bridge part of the gap that exists between the resource curse literature and economic historical research on natural resources by analysing four resource-abundant countries. The study proposes that at the sectoral level, the determinants of growth in resource-based industries were mostly similar in the late 19th and late 20th centuries. However, we also argue that the relative contribution of natural resources to economic growth might have been declining during the late twentieth century. The evidence comes from an analysis of the forestry sector in Finland and Sweden between 1860 and 1910 and the palm oil industry in Indonesia and Malaysia between 1970 and 2016.

Outgoing longwave radiation (OLR) data are one of the key factors in studying the radiation balance of the earth–atmosphere system in East Asia. It is of great significance to explore the influence factors on OLR. This paper processes the data of nearly 19 years, from September 2002 to February 2022, and conducts in-depth research using the exponential smoothing method, empirical orthogonal decomposition (EOF), correlation analysis, and other methods. We found that the spatial distribution of OLR is zonal symmetry and gradually decreases with the increase of latitude. Using EOF analysis, it is found that the total variance contribution of the first four decomposed spatial features exceeds 70%, and the overall change trend of the four-time coefficients in the past 19 years all show a downward trend. OLR is positively correlated with total column water vapor (TCWV), air temperature (AT), and cloud top temperature (CTT), but negatively correlated with cloud top pressure (CTP). OLR has a similar spatial correlation distribution with TCWV and AT, while the spatial correlation between OLR and CTP is opposite to the first two parameters. In most parts of East Asia, the spatial correlation with CTT exceeds 0.8. The change in OLR value is affected by various meteorological parameters. In East Asia, the positive correlation between 30° N and 60° N is significantly affected by TCWV, AT, and CTT; and the negative correlation is more significantly affected by CTP. At 0–25° N, the positive correlation is significantly affected by CTP and CTT, while the negative correlation is significantly affected by TCWV and AT. [ABSTRACT FROM AUTHOR]

Spread-F (SF) is one of the most important types of the ionospheric irregularities as it causes ionospheric scintillation which can severely affect the performance and reliability of communication, navigation, and radar systems. The ionosonde provides the most effective and economical way to study the ionosphere and SF. However, the manual identification of SF from an ionogram is boring and hard work. To automatically identify SF on the ionogram and extend the study of SF into the middle and low latitudes of East Asia, this paper presents a statistical analysis of SF in this region, based on the naïve Bayesian classifier. The results showed that the accuracy of automatic identification reached up to 97% on both the validation datasets and test datasets composed of Mohe, I-Cheon, Jeju, Wuhan, and Sanya ionograms, suggesting that it is a promising way to automatically identify SF on ionograms. Based on the classification results, the statistical analysis shows that SF has a complicated morphology in the middle and low latitudes of East Asia. Specifically, there is a peak of occurrence of SF in the summer in I-Cheon, Jeju, Sanya, and Wuhan; however, the Mohe station has the highest occurrence rate of SF in December. The different seasonal variations of SF might be due to the different geographic local conditions, such as the inland-coastal differences and formation mechanism differences at these latitudes. Moreover, SF occurs more easily in the post-midnight hours when compared with the pre-midnight period in these stations, which is consistent with the previous results. Furthermore, this paper extracts the frequency SF (FSF) index and range SF (RSF) index to characterize the features of SF. The results shows that the most intense FSF/RSF appeared in the height range of 220–300 km/1–7 MHz in these stations, although there are different magnitude extensions on different season in these regions. In particular, strong spread-F (SSF) reached its maximum at the equinox at Sanya, confirming the frequent SSF occurrence at the equinox at the equator and low latitudes. These results would be helpful for understanding the characteristics of SF in East Asia. [ABSTRACT FROM AUTHOR]

The narrative of 'imposition', whereby 'international law' is said to have been imposed by Western powers on China, was shared by both English and Chinese literatures, albeit each holding contrasting views on the meaning and consequences of such 'imposition'. This paper seeks to highlight the nuances in the shared 'imposition' narratives and challenge many of its presumptions through a chronological re-examination. First, by tracing the 'encounter' back to the 16th century, the unity and diversity between the Sinocentric and Eurocentric orders were re-examined. Second, by comparing the Chinese and English text of the Opium War Treaties, this paper reveals how the Qing Empire also sought to accommodate the Eurocentric order in its own term from 1842 to 1860. Third, by seeing the 'encounter' as an evolutionary rather than a revolutionary process, this paper demonstrates how the concept of 'China as a state' evolved from the Celestial Empire's 'encounter' with 'international law'.

The issue of biological invasions in aquatic ecosystems is becoming increasingly severe in the contemporary world. Due to the lack of monitoring and management systems for aquatic invasive species, the difficulty in identifying aquatic invasive species, and the limited effectiveness of conventional control methods in aquatic environments, biological control in water bodies is comparatively more challenging than other types of interventions. In recent years, environmental DNA (eDNA) survey methods have rapidly developed in various fields, such as biological monitoring, community ecology, paleoenvironmental research, conservation biology, and invasion ecology, due to their unique advantages of being rapid, sensitive, efficient, and non-invasive. Because of these characteristics, this innovative molecular approach has gained wider acceptance and is being increasingly utilized for the detection of biological diversity in aquatic environments. Furthermore, it has emerged as a novel technology to address the pressing and significant issue of aquatic invasive species in the vast freshwater and marine resources of the East Asian region. This paper summarizes a variety of literature sources to summarize the major aquatic invasive species in East Asian countries and the current application status of eDNA technology in their survey processes. Using China as a case study, it expounds on the prospective incorporation of the 4E strategy with eDNA technology for the surveillance of biological invasions. Furthermore, it explores the potential prospects of eDNA technology in species diversity management and policy formulation, offering theoretical guidance for establishing aquatic invasive species monitoring systems. From a technological standpoint, the integration of eDNA technology with the 4E strategy holds significant potential for application, thereby offering a promising reference for the formulation of policies related to the management of aquatic biological invasions and biodiversity.

The People's Republic of China (PRC), the Special Administrative Region of Hong Kong, the Republic of China (Taiwan) and the Republic of Singapore represent different types of political regimes and provide a fascinating contrast concerning their performance with regard to the global conflict between liberal democracies and autocracies. This paper examines briefly their common historical backgrounds and provides a detailed analysis of common 'Asian' cultural features and popular support for democracy on the micro-level. It then systematically assesses their performance concerning liberal democracy and quality, governance scores, and socio-economic development. Finally, the reactions to the Covid-19 pandemic are documented showing again specific regime characteristics. We use most recent V-Dem, World Bank, United Nations Development Programme, World Values Surveys and similar data. The conclusions point to possible international consequences and the crucial position of Taiwan. [ABSTRACT FROM AUTHOR]

This is an extended editors’ commentary on the topical collection “Historical and recent change in extreme climate over East Asia”, which collects a total of 15 papers related to the change and variability of extreme climate events in East Asia over the last few hundreds years. The extreme climate events are broadly classified into three categories: temperature and extreme warmth/coldness, precipitation and floods/droughts and western North Pacific typhoons. This commentary briefly summarizes the main findings presented in each paper in this topical collection, and outlines the implications of these findings for monitoring, detecting and modeling of regional climate change and for studying climate change impacts and adaptability. It also assesses the uncertainties of these studies, as well as the remaining knowledge gaps that should be filled in the future. One solid conclusion we can draw from these studies is that there was a marked decadal to multi-decadal variability of extreme climate events in East Asia in recent history, and the extreme events as observed during the last decades of the instrumental era were still within the range of natural variability except for some of those related to temperature. More severe and enduring droughts occurred in the early 20 th century or the earlier periods of history, frequently leading to great famines in northern China. Uncertainties remain in reconstructing historical extreme climate events and analyzing the early instrumental records. Further research could focus on the improvement of methodology in proxy based reconstruction of multi-decadal variations of surface air temperature and precipitation/drought, the recovery, digitization, calibration and verification of the early instrumental records, and the mechanisms of the observed multi-decadal variability of extreme climate in the region.

While research on new venture entrepreneurship has been predominantly conducted in Western countries, East Asian start-ups have gained global relevance in recent years. In this article, we systematically review studies on new venture entrepreneurship in East Asia published in Social Science Citation Index (SSCI)-listed journals between 2000 and 2020 and find that the number of papers annually published has been rapidly increasing. However, the research body is highly unbalanced, as most articles are single-country studies focused on China, apply a quantitative methodology, and concentrate on topics such as entrepreneurial strategies and new venture entrepreneurs' personal attributes and networks. Moreover, a majority of studies provides no or only a weak consideration of the national or subnational context. More strongly contextualized research on countries such as Japan and South Korea and on less studied themes such as culture, entrepreneurial financing, entrepreneurial teams, new venture internationalization and new venture entrepreneurial intention is desirable.

In this paper, a statistical analysis of the diurnal, seasonal and solar cycle variation in the TEC longitudinal difference in midlatitudes of East Asia is presented using CODE GIMs data in 2015–2019. Moreover, the empirical neutral wind model HWM-14 and geomagnetic field model IGRF-2020 were employed to analyze the influence of geomagnetic configuration-neutral wind mechanism on the TEC longitudinal difference, and the F2 layer peak electron density (NmF2) data from the Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) were also used to study the role of local electron density in the TEC longitudinal difference. For the high solar activity year, the results show that east-west TEC longitudinal difference index Re/w is negative in the noon and positive at evening-night. Moreover, the longitudinal difference of daytime TEC is most evident in summer, less in autumn and least in spring and winter, while the nighttime difference is most obvious in equinox, followed by summer and winter during nighttime. The model simulation shows that the TEC longitude difference around noon is mainly caused by the zonal wind-declination mechanism, and a 4-h time delay seems to be an optimal result for the vertical drift velocity to cause the longitudinal TEC difference during pre-noon hours. At night, the uplifting electron flux, which is a product of local electron density and vertical drift velocity, shows a good correlation with Re/w, indicating that the local electron density is also an important factor affecting the TEC longitudinal difference during the nighttime. Moreover, there was about a 3-h time delay between the TEC longitudinal variations and the uplifting electron flux at night. For the low solar activity years, the western TEC is greater than eastern TEC during most of the year except in the summer nighttime. The TEC diurnal variation in the east and west suggested that the nighttime Re/w should be related to other physical process, such as the midlatitude summer nighttime anomaly (MSNA) in the east and the ionospheric nighttime enhancement (INE). The current study provides evidence for the longitudinal difference of NmF2 in East Asian midlatitudes and geomagnetic configuration-neutral wind mechanism proposed in previous studies and finds some new features which need further studying to improve our current understanding of ionospheric longitudinal difference in the low solar activity years. The results provide new insight into TEC longitudinal variations at midlatitudes, and they can contribute to understanding the ionosphere-thermosphere coupling system. [ABSTRACT FROM AUTHOR]

The ionospheric equivalent slab thickness (EST, also named τ) is defined as the ratio of the total electron content (TEC) to the F2-layer peak electron density (NmF2), and it is a significant parameter representative of the ionosphere. This paper presents a comprehensive statistical study of the ionospheric slab thickness at Yakutsk, located at the high latitude of East Asia, using the GPS-TEC and ionosonde NmF2 data for the years 2010–2017. The results show that the τ has different diurnal and seasonal variations in high- and low-solar-activity years, and the τ is greatest in the winter, followed by the equinox, and it is smallest in the summer in both high- and low-solar-activity years, except during the noontime of low-solar-activity years. Specifically, the τ in inter of high-solar-activity year shows an approximate single peak pattern with the peak around noon, while it displays a double-peak pattern with the pre-sunrise and sunset peaks in winter of the low-solar-activity years. Moreover, the τ in the summer and equinox have smaller diurnal variations, and there are peaks with different magnitudes during the sunrise and post-sunset periods. The mainly diurnal variation of τ in different seasons of high- and low-solar-activity years can be explained within the framework of relative variation of TEC and NmF2 during the corresponding period. By defining the disturbance index (DI), which can visually assess the relationship between instantaneous values and the median, we found that the geomagnetic storm would enhance the τ at Yakutsk. An example on 7 June 2013 is also presented to analyze the physical mechanism. It should be due to the intense particle precipitation and expanded plasma convection electric field during the storm at high-latitude Yakutsk station. The results would improve the current understanding of climatological and storm-time behavior of τ at high latitudes in East Asia. [ABSTRACT FROM AUTHOR]

This paper aims to investigate how selected regional trade agreements (RTAs) affect trade efficiency in East Asia, which is measured by the ratio of actual exports to their maximum potential export value. To achieve this, we use a stochastic frontier gravity model and bilateral trade data of 16 countries from 1990 to 2018. Our results indicate that RTAs generally improve trade efficiency between member countries. Moreover, we distinguish between intra-bloc and extra-bloc trade, and found that export diversion due to RTAs is rare in East Asia. On the other hand, our result shows that the imports of ASEAN countries tend to divert away from non-members. [ABSTRACT FROM AUTHOR]

Traditional sending countries of international students in East Asia have emerged as increasingly desirable higher education destinations. Yet little is known about the experiences of international students in East Asia as most research focuses on those in the Anglophone West. In this study, we explored the trajectory and interactions between intercultural communication, acculturation strategies, and adaptation outcomes of international students in Hong Kong. We conducted in-depth interviews with international students from other Asian countries (n = 14) and Western countries (n = 10). Our research reveals a paradox where international students’ eagerness to engage with diverse peers is overshadowed by limited interaction with local students. Cultural and language differences were perceived to create a wall separating them from the local students, inhibiting a cosmopolitan learning environment. Additionally, international students often gravitate towards familiar national or cultural groups, which can hinder broader integration. Sociocultural challenges and outsider feelings were also reported, potentially leading to psychological issues. We propose an interactive framework that connects intercultural communication, acculturation strategies, and adaptation outcomes. The paper offers theoretical and practical insights for policymakers, administrators, educators, and students, aiming to foster effective communication and successful acculturation in a multilingual and multicultural educational setting.

This introductory article aims to present an overview of the contribution that East Asian scholars have made to Translation Studies as a field of enquiry. Apart from some contributions from countries such as Thailand and Vietnam, most of the publications of the last four decades involve Chinese, Korean, and Japanese themes and are authored by scholars from these areas or focused on the languages and cultures of China, Korea and Japan. The article considers the publications on audiovisual as well as literary and news translation, highlighting articles, book chapters and monographs that have delved into translations involving East Asian languages, notably Chinese, Korean and Japanese. The final section introduces the selection of papers that conform this thematic issue. [ABSTRACT FROM AUTHOR]

Although the Chinese, Japanese, and Korean academy gardens in East Asia are of the same origin, they have gradually followed different paths owing to the influence of natural and cultural environments. This paper introduces in detail the site selection, enclosure, architecture, plants, water system, and stone building of the Yuelu Academy in China, Katsura Imperial Villa in Japan, and Pingshan Academy in Korea and compares and analyzes the differences between the three countries' academy gardens, thus helping us to better understand and appreciate East Asian academy gardens.

As countries scramble for cleaner energy production and to meet carbon reduction targets, natural gas seems to become an increasingly attractive option with liquified natural gas (LNG) as a popular transportation choice. In this paper, we first conduct a literature review and discuss the various factors affecting the global natural gas market, its recent history, current state, and future. Then we look at the possibility of East Asia becoming an alternative market to Europe for Russian LNG. We also bring in the US both as a political force that employs economic sanctions and as a potential LNG supplier. As a case study, we define a 3-player game between Russia, The United States, and Japan which results in relative market stability. In the case of sanctions against Russia, we conclude that it will lose its foothold in the Japanese market in the long term. Finally, we discuss the potential of LNG trading as the first step for East Asia's energy transition to a low-carbon economy. [ABSTRACT FROM AUTHOR]

Since the 1980s, East Asian regions have gradually grown into the biggest importers and producers of animal products in the world. Among them, Taiwan has become the world's biggest pork exporter since 1990 but the export market suddenly crashed owing to the outbreak of Foot and Mouth Disease in 1997. Since then, biosecurity has been increasingly deemed necessary to manage animal lives. While food regime theory has been steadily employed by critical scholars to examine this rapid 'meatification' process in East Asia, it has suffered from 'inclusionary bias', paying less attention to the consequences of market failure. Informed by social studies of economisation and marketisation and work on multispecies, I contend that the studies of global agri-food production need to be more attentive to the issue of disarticulations: the 'dark sides' of network incorporation. With a specific focus on the Taiwanese pork sector after 1997, this paper argues that 'politics of domestication' emerged as markets broke down. I outline three characteristics which have shaped the politics of domestication: disentanglement, marginalisation, and co-becoming. While biosecurity seeks to manage life by separating hog bodies from other species, this paper points out that this enclosure strategy is always subject to threats from within.

Societal Impact Statement Summary The discovery of a new genus within the family Thismiaceae, known as fairy lanterns, marks a significant scientific milestone in Japan, a country renowned for its botanical research. The unearthing of a new genus, especially in a well‐documented flora like Japan, is both rare and monumental. Unlike other fairy lanterns that bloom under leaf litter and can be easily overlooked, the new genus and species, Relictithismia kimotsukiensis, often does not even emerge above the surface of the soil when flowering. This captivating characteristic not only enriches our knowledge of botanical diversity but also emphasizes the importance of preserving natural habitats that harbor such rare species.The family Thismiaceae, known as “fairy lanterns”, is distinguished by its urn‐ or bell‐shaped, glasswork‐like flowers with basally fused tepals and its dependence on specific fungi for carbon. A new genus and species, Relictithismia kimotsukiensis, has been discovered in southern Japan. This species is notable for its unique anther‐stigma contact, hitherto unreported in the other Thismiaceae. Unlike typical fairy lanterns that bloom just above the leaf litter, Relictithismia often flowers beneath it. The underground habit is potentially associated with self‐pollination. The discovery of Relictithismia enhances our understanding of evolutionary pathways within the Thismiaceae, as it possesses characteristics previously thought to be unique to Thismia (the annulus with drooping stamens) as well as traits found in other genera (free stamens without expanded connectives). This paper reviews the morphology, ecology, and evolutionary history of Relictithismia, offering insights into the peculiarities of these enigmatic plants. [ABSTRACT FROM AUTHOR]

This paper aims to contribute to global social theory by contextualizing modernity/coloniality in East Asia. It begins with a reconstruction and evaluation of three sociological accounts of East Asian modernity, namely Kazuko Tsurumi's theory of endogenous development, Sun Liping's theory of communist civilization, and Chang Kyung Sup's theory of compressed modernity. Despite their insights, these theorists fail to transcend the Eurocentrism and methodological nationalism implicit in the paradigm of latecomer modernization. These problems can be better addressed by anti‐colonial perspectives, including Tani Barlow's colonial modernity, Chen Kuan‐Hsing's inter‐Asia, Xie Lizhong's post‐Western sociology, and Wang Mingming's civilizational anthropology. Yet European hegemony continues to define the spatiotemporal frame of these perspectives. To overcome the lingering problem of Eurocentrism, Laura Doyle's notion of inter‐imperiality is employed to highlight the power‐laden interaction and interdependence among imperial powers in the global and regional history of East Asia. This alternative approach, I argue, can shed new light on East Asian modernity and delineate its dialectical formation. [ABSTRACT FROM AUTHOR]

Like much of the rest of the world, East Asia (Northeast and Southeast Asia) has recently experienced a democratic "fall" in which several electoral democracies have undergone autocratization. This synchronized with China's rise through what can be called illiberal realignment as autocratizing regimes in the region have sought increasing material and ideological support from Beijing in the face of Western human rights criticism and occasional (although usually only the threat of) sanctions. China has viewed this regress as a rejection of "Western-style democracy." Yet a democratic "spring" which preceded the fall left a legacy of democratic normativity in the region as backsliding regimes continued to seek legitimacy through (however unfair and unfree) elections and (partial) liberalization. Residual democratic normativity combined with geopolitical insecurities have limited the region's illiberal realignment toward China during this democratic fall. [ABSTRACT FROM AUTHOR]

The family Thismiaceae, known as "fairy lanterns" for their urn- or bell-shaped flowers with basally fused tepals, consists of non-photosynthetic flowering monocots mainly in tropical regions, extending into subtropical and temperate areas. Here, we propose a new mycoheterotrophic genus, Relictithismia Suetsugu & Tagane (Thismiaceae), with its monotypic species Relictithismia kimotsukiensis Suetsugu, Yas.Nakam. & Tagane from Kimotsuki Mountains in the Osumi Peninsula, Kagoshima Prefecture, Kyushu Island, southern Japan. Relictithismia resembles Haplothismia Airy Shaw in having a cluster of tuberous roots, a feature previously observed only in this genus within the family Thismiaceae. However, it differs in having solitary flowers (vs. 2–6-flowered pseudo-raceme in Haplothismia), anther thecae largely separated (vs. connate), and the presence of an annulus (vs. absent). Additionally, Relictithismia differs from the geographically overlapping genus Thismia Griff. in its stamen structure and the position of the annulus. In Relictithismia, the stamens lack connectives, and its free filaments arise from the annulus located inside the perianth mouth, while in Thismia, the stamens typically have connate connectives, forming a staminal tube pendulous from the annulus located at the mouth of the floral tube. Our morphological and phylogenetic data indicated that R. kimotsukiensis holds an early-diverging position within the family, situated outside the Old World Thismia clade. This paper offers an extensive description and color photographs of R. kimotsukiensis, complemented by notes on its phylogenetic relationship and evolutionary history. [ABSTRACT FROM AUTHOR]
