Professor Gavin W. Jones dedicated an impressive 58-year career to extensive research on various aspects of population and development in Asia. As a seasoned consultant, he was pivotal in shaping population policies and programs in more than 10 Asian countries, impacting the region’s demographic landscape. Throughout his illustrious career, Gavin has left an indelible mark through his prolific publications, with 30 books, over 180 journal articles, and book chapters. His body of work covered various demographic subjects in the Asia-Pacific region, significantly contributing to our understanding of population dynamics in Southeast, South, and East Asia. His research has been instrumental in informing policy decisions in these regions by providing evidence-based recommendations. In addition to his consultancy and academic achievements, Gavin actively engaged in professional networks, fostering collaborations and facilitating knowledge exchange among fellow demographers and researchers. His commitment to mentorship has been invaluable, nurturing emerging demographers and supporting the next generation of population scholars in population and development. The present paper aims to delve into Professor Gavin W. Jones’s specific contributions to elucidate the intricate relationship between population and development, an area that inevitably intersects with other papers in this festschrift on marriage, fertility, and urbanization.

This paper highlights the highly contingent and constrained possibilities for states concerned with gaining and maintaining economic and, relatedly, strategic advantage in East Asia in a world dominated by global value chains (GVCs) owned and controlled by transnational capital. While the reorganisation of production has given rise to new contender states such as China, challenging the economic and strategic positions of others, the ability for states to engage in non-market conforming behaviour designed to reduce technological dependence, accumulate reserves and embolden national positions against competitors is far more constrained than it once was. Prioritising the relative power and leverage of states operating in various contexts over time, three types of state are identified within contemporary East Asia: former developmental states under persistent competitive pressures compelling very different policy agendas to those that underpinned their respective development stories; a somewhat exceptional constrained "aspirant state", attempting mercantilist strategies to achieve strategic upgrading under the spectre of systemic exclusion and formidable domestic challenges; and, finally, relatively vulnerable "eke-out" competition states, attempting to leverage labour cost, geography and regulation to maintain economic relevance within the context of hyper competitiveness while also engaging in forms of quarantining and patronage. Our overarching argument is that the latitude to both pursue and leverage ES strategies common in the past is all but gone, even for the most powerful of contender states. [ABSTRACT FROM AUTHOR]

Postponement of first births is a key cause of declining fertility rates, especially in East Asia where recovery from delayed childbearing has been weak. This paper investigates achievement of ideal ages at marriage and first birth in Singapore using survey data on 657 married women aged 25–34. Almost 50 per cent marry within one year of their ideal age, but less than 30 per cent have their first child within six months of their ideal interval to first birth, with around 50 per cent waiting longer than ideal. The high proportion of women experiencing a longer-than-ideal first birth interval was observed across all age and educational groups. Regression results show that co-residence with a foreign domestic worker and paid leave entitlements are associated with higher probability of achieving their ideal first birth interval, whereas availability of parents/in-laws, husband's help and unpaid leave do not reduce time to childbearing.

Purpose – The region's universities are “riding a tiger” of university rankings in East Asian higher education, in a race to gain in the list of the world's top 100 universities. While this race impacts universities throughout the world, it takes on particular importance in East Asia due to the stage of university development and the needs of regional societies. The purposes of this paper are to: To examine the emergent global emphasis on world university ranking as a driver of change in higher education, To discuss how the world university rankings are impacting East Asian universities, To assess consequences for higher education in the region, To explore options for leading universities in a more meaningful direction in East Asia. Design/methodology/approach – This paper examines research and commentary on the impact of world university rankings on universities in East Asia. Findings – This paper proposes that the world university rankings have, over a relatively short period of time, had unanticipated but potentially insidious effects on higher education in East Asia. This paper proposes that the “tiger” is carrying most East Asian universities towards goals that may not reflect the aspirations of their societies, or the people that work and study in them. Yet, climbing off the “tiger” often feels just as risky as hanging on to its back. Instead of seeking to lay blame at any one party, the paper suggests that the problem is systemic in nature. Multiple parts of the system need to change in order to achieve effects in the distal parts (e.g. faculty, students, and society). Only leadership can bring about this type of change. The scholarly community must gain some degree of input and monitoring over the rules of the rankings game. Only by joining hands can university leaders in the region change the “Ranking Game” to reflect the reality and needs of university development and social contribution in East Asia. Only by cooperation can the region's university leaders create reciprocal pressure on other parts of the system. In response to systemic problems, “I” may be powerless, but “we” are not. Originality/value – The originality and value of this paper lie in its aim to elevate underlying dissatisfaction with the rankings into a broader and more explicit debate over the direction in which East Asian universities are riding on the back of the tiger.

In the larger context of globalisation and internationalization, navigating business operations in a multicultural environment is no easy task. The Far East has always fascinated the West through the uniqueness of its traditions, while at the same time remaining mysterious and rather difficult to assimilate for those who have not experienced culture shock before. Therefore, this paper strives to emphasise the importance of familiarising business students with the key issues related to cultural awareness and communication, focusing on Asian cultures in contrast to the Western world since, in the light of the latest political and economic developments leading to an ever-increasing Chinese dominance, they will undoubtedly be putting that information to good use.

Purpose The purpose of this paper is to synthesize findings from studies of principal instructional leadership conducted in five East Asian societies. The authors first identify similarities and then differences in approaches to instructional leadership across the societies. Then the findings of the synthesis are compared with broad findings from the global literature on principal instructional leadership.Design/methodology/approach The paper employs a thematic approach to synthesizing findings from the five qualitative studies.Findings The authors identified numerous similarities in practices of instructional leadership across the five societies. These included first, a top-down approach to defining the mission and goals of schools whereby principals worked within a fairly narrow zone of discretion. Second, principals devoted relatively little attention to coordinating the curriculum due to working within strict national curriculum frameworks. Third, principals executed their instructional leadership practices with an ever-present sense of the need to honor hierarchical relations and maintain harmony among staff and other stakeholders. Differences across the five societies centered on the extent to which the instructional leadership role of principals was explicitly defined and the extent to which they received training for the role.Originality/value This synthesis sought to build upon reviews of research published in a special issue of this journal two years ago. The synthesis and this body of research papers have contributed toward moving empirical research on educational leadership broadly, and instructional leadership in particular, forward in East Asia.

Yeung H. W.-C. Regional development and the competitive dynamics of global production networks: an East Asian perspective, Regional Studies. The debate on the nature and dynamics of regional development in both academic and policy circles has now moved on from the earlier focus on endogenous regional assets to analysing the complex relationship between globalization and regional change. This position paper attempts to engage with this debate through the experience of regional development in East Asia. The paper shows that regional development cannot be understood independently of the changing dynamics of global production networks. While the existing literature on East Asia tends to focus on the state as the key driver of economic development at the national and regional levels, it is argued that the developmental state is a necessary but not sufficient condition for regional development to take place. Instead, one needs to study the complex strategic coupling of those economic actors, particularly large business firms, operating in specific regions in Asia with their lead firm counterparts orchestrating production networks on a global basis...

This paper discusses a strategy for accelerating the development of a regionally grounded knowledge base on educational leadership and management in East Asia. The study reviews data on patterns of knowledge production in East Asia, and employs the findings in the development of a strategy for increasing knowledge production. The study concludes that a suitable coordination strategy for the region should incorporate formal and informal strategies, be intermediate in scale and organised around a common research agenda. The authors propose that the substantive findings and the method of strategy analysis may also be relevant for academic leaders in other developing regions of the world. [ABSTRACT FROM PUBLISHER]

The role of school leadership in educational reform has reached the status of a truism, and led to major changes in school leader recruitment, selection, training and appraisal. While similar policy trends are evident in East Asia, the empirical knowledge base underlying these measures is distorted and lacking in validation. This paper begins by offering evidence in support of this assertion. Then it examines the process of knowledge production as it has unfolded in Western academic contexts. Finally, it assesses the context in East Asia and offers recommendations for accelerating the development of a regionally valid knowledge base. [ABSTRACT FROM PUBLISHER]

Business organizations constantly seek creative innovation as a means to differentiate from competitors in the marketplace. Design Thinking (DT) has emerged in recent years as a methodology that promises organizations a means to innovate products and services. Yet, many East Asian organizations have only begun to consider DT as a method towards generating product and service ideas, and scholars cite cultural factors as barriers to DT adoption. This paper examines how East Asian firms implement DT in light of cultural barriers and explicates a framework that identifies four implementation models based on level of commitment and an internal/external orientation. The four models are the baked-in approach, the "special ops" design lab, outsourcing, and the creative retreat. The findings contribute to the design thinking literature, which focuses on why DT works, but has only produced limited insights into how firms implement DT into organizational culture.

Internal and international migration have increased exponentially in scale, complexity and significance in the last two decades. There are often strong relationships between internal and international migration, but they remain little understood because the two types of movement are conceptualised, measured and studied separately. This paper is divided into two parts. The first summarises the areas of both convergence and divergence in the types, patterns, causes and consequences of internal and international migration in the Asian region. These are considered partially in the context of the complex relationship between migration and development. It is shown that there is more convergence than divergence conceptually and theoretically. The second part of the paper addresses the issue of linkages between internal and international migration. This model argues that on the one hand international migrants usually engage in a different pattern of internal migration than the established population at the destination. It also suggests that in some cases international migration itself may influence the internal migration patterns of the resident population. On the other hand there are also linkages in 'origin' countries where particular patterns of internal migration precede international migration. Copyright © 2015 John Wiley & Sons, Ltd.

The objective of this paper is to establish conceptual foundations of analyzing the economic dimensions of Brexit. The International Financial-Trade Exchange Leaking Index (TIFTEL-Index) attempts to analyze and compare pre-Brexit versus post-Brexit international trade and international financial transactions between East and Southeast Asia and Europe. TIFTEL-index is based on three main variables, namely (1) international trade exchange marginal rate (∆Τ′), (2) international financial exchange marginal rate (∆σ′), and (3) GDP in real prices growth marginal rate (∆γ). Simulation findings indicate that Brexit will have only a limited negative effect on the world economy. In addition, Brexit will affect East Asia more than Southeast Asia region.

Hikikomori, which originated in Japan, refers to the condition where youths withdraw into the home and do not participate in society for an extended period of time. Recent updates on hikikomori presentation within the region were exchanged at a Hikikomori Round Table and Regional Symposium (HRTRS) discussion late 2017, leading to this perspective paper. Hikikomori presents as an overall homogeneous construct, while diversity in clinical presentation exists across East Asian countries. We examined the various presentations, risk factors, theoretical frameworks, and classification issues about hikikomori. In particular, specific risk factors have emerged to some degree across the region, while some are more locale specific. We propose that hikikomori youths have differential onset and developmental patterns, potentially resulting in heterogeneous presentation. We briefly summarized existing interventions in the East Asian region. Intervention strategies need to be tailored to different subtypes. A multicomponent approach would address complexity, multifactorial onset, and development of the condition. The HRTRS presented to participating countries the opportunity to collectively work toward a more universal definition of the hikikomori condition and explored innovative ways to shape existing service structures. Opportunities for participating countries described pertain to early detection of cases, adoption of assessment tools, and improved intervention services. [ABSTRACT FROM AUTHOR]

Ancient East Asia is the second oldest "protobeilic area" and pristine state system of international relations within the global international system, after West Asia (ancient Near East). In a previous study Cioffi-Revilla and Lai (1995) reported the first findings on the origins and evolution of war and politics in ancient China (Legendary, Xia [Hsia], Shang, and Western Thou [Chou] periods), Ca. 2700 B.c. to 722 B.C. In this paper we make public an expanded data set (N = 104 cases, 12 variables; version 2.0), explaining our sources, measurements, and data quality control procedures. The new data set will permit investigators to test hypotheses about warfare distributions, ethnic and protracted conflicts, time series, periodicity, system dynamics, and structural relationships (e.g., war-polarity theories). This new long-range data set should also promote a new stage in comparative analyses of the universal and particular properties of warfare and international systems, both cross-polity and longitudinally.

Since the proclamation of a mobility turn in the 2000s, scholars have populated the field with invaluable insights on what it means to move, and what the politics of movement are. One particularly useful thread revolves around the issue of infrastructures, which have generally been taken to mean the manifest forms of moorings and fixities that help order and give shape to mobilities. Yet, while significant inroads have been made in delineating the morphologies of transport infrastructures, mobilities research has been relatively reticent about the organisational structures, orders and arrangements that give rise to another key mobile phenomenon of our time — international migration. In this editorial introduction, we lay down some groundwork on the productive and political nature of infrastructures that likewise affect and inform the way (im)mobilities are contingently created and parsed in migration. Looking through the prism of East and Southeast Asia and its migration infrastructures, we take advantage of the ‘new’ infrastructural configurations in an emerging empirical context to point to some directions by which mobilities researchers can more rigorously interrogate ‘migration’ as another socially meaningful and specific form of mobility that exceeds a mere displacement of people or change in national domicile.

During the 2nd World War, large numbers of allied military personnel in south-east Asia became prisoners-of-war (POWs) of the Japanese. During their internment of three and a half years, they suffered undernutrition, exposure to tropical diseases and frequently overwork. Perhaps the harshest POW experience was the construction of the railway between Thailand and Burma. This paper explores the medical conditions during Far East imprisonment, and in particular on the Thai-Burma Railway, as well as the long-term health effects in post-war decades.

Background: This meta-analysis study summarized the available information on the prevalence of thermotolerant Campylobacter jejuni and Campylobacter coli among poultry products in Asia; Methods: Exhaustive literature search was conducted and 30 studies were included. A number of multilevel random-effect meta-analysis models were used to calculate their pooled prevalence and compare each Asian regions; Results: The pooled prevalence for C.jejuni was 34%. On a separate meta-analysis for East Asia (EA), Middle East (ME) and South Asia (SA) and Southeast Asia (SEA), the pooled prevalences for C. jejuni were 33%, 37% and 33%, respectively. Moreover, results showed that there was significant heterogeneity and no significant publication bias. Conversely, the pooled prevalence for C. coli was 13%. On separate analysis by region, the pooled prevalences for EA, ME, and SEA were 10%, 18% and 12.08%, respectively. Significant heterogeneity was observed and there was no publication bias detected in the EA and the SEA; Conclusions: Overall, the high incidence of both C. jejuni and C. coli infections across Asia highlight the public health importance of these pathogens. Moreover, the meta-analysis of C. jejuni and C. coli prevalence across Asia gives crucial insights into the public health concerns connected with these pathogens. [ABSTRACT FROM AUTHOR]

In this paper the model outputs from the Coupled Model Intercomparison Project (CMIP) phase 5 (CMIP5) are used to examine the climatology and interannual variability of the East Asian winter monsoon (EAWM). The multimodel ensemble (MME) is able to reproduce reasonably well the circulation features of the EAWM. The simulated surface air temperature still suffers from a cold bias over East Asia, but this bias is reduced compared with CMIP phase 3 models. The intermodel spread is relatively small for the large-scale circulations, but is large for the lower-tropospheric meridional wind and precipitation along the East Asian coast. The interannual variability of the EAWM-related circulations can be captured by most of the models. A general bias is that the simulated variability is slightly weaker than in the observations. Based on a selected dynamic EAWM index, the patterns of the EAWM-related anomalies are well reproduced in MME although the simulated anomalies are slightly weaker than the observations. One general bias is that the northeasterly anomalies over East Asia cannot be captured to the south of 30°N. This bias may arise both from the inadequacies of the EAWM index and from the ability of models to capture the EAWM-related tropical-extratropical interactions. The ENSO-EAWM relationship is then evaluated and about half of the models can successfully capture the observed ENSO-EAWM relationship, including the significant negative correlation between Niño-3.4 and EAWM indices and the anomalous anticyclone (or cyclone) over the northwestern Pacific. The success of these models is attributed to the reasonable simulation of both ENSO's spatial structure and its strength of interannual variability. [ABSTRACT FROM AUTHOR]

Based on optimum currency areas (OCA) theory and recent developments in the exchange rate regime literature, this paper evaluates the level of preparedness of East Asia for monetary integration by using the EMU as benchmark. Ten macroeconomic dimensions are explored in which the first five facets are measured relative to a reference country, namely the US, Japan, or China whilst the remaining five facets are measured in absolute terms, over the most recent years. In some ways, the exercise does signify the relative economic dominance of the three largest economies to the region. Results suggest that East Asia might be fairly prepared for a monetary integration especially when the reference country is the US. Another interesting observation is that amongst the eurozone founding members, Ireland has shown the lowest degree of conformity in a number of the criteria. [ABSTRACT FROM AUTHOR]

• 18 new Ancestry informative markers (AIMs) were screened from the 1000 Genomes Project. • A novel panel of 18 AIMs can improve ancestry distinctions among Asian populations. • Our panel could distinguish the GIH (Gujarati Indian in Houston, TX) from other South Asian groups. At present, several mature ancestry informative SNP (AISNP) panels are used to distinguish between continental regions of the world, but a more accurate division within the continent requires a secondary panel to complete. However, many AISNPs for the subgroup ancestry inference are selected from the Kidd Lab panel of 55 AISNPs or other published papers. These panels inevitably lack valuable markers for subgroup ancestry inference. Therefore, instead of choosing from the published panels, we used the 1000 Genomes Project to screen potentially informational markers in Asian populations, including single nucleotide polymorphisms (SNPs) and insertion/deletion polymorphisms (InDels). The allele frequencies of all autosomal SNPs and InDels of the 1000 Genomes Project were compared between 10 populations in Asia to identify markers with the largest pairwise allele frequency differences. Finally, we established a second-tier panel of 18 AIMs in this study, which not only divided the 26 populations of the 1000 Genomes Project into six clusters, but also divided the Asia subgroup into four clusters: Gujarati, East Asia, Southeast Asia and South Asia.

During glacial periods, the East Asian monsoon is typically thought to have been stronger in boreal winters and weaker in boreal summers. It is unclear, however, whether this view is true at larger scales and to what extent the East Asian monsoon responds to glacial conditions as a whole. Using all experiments conducted as part of the Paleoclimate Modeling Intercomparison Project (PMIP), this paper examines East Asian monsoon climatology during the Last Glacial Maximum (LGM), around 21 000 calendar years ago. In contrast to conclusions drawn from sparse proxy data, the intensity of the East Asian winter (December-February) monsoon (EAWM) during the LGM, as measured by regionally averaged meridional wind speed at 850 hPa, was found to vary both in sign and magnitude, with reference to baseline climate, across the PMIP simulations. It strengthened in 10 out of the 21 models but weakened in the remaining 11 models, with an average weakening of 4% for the 21-model ensemble mean (15% for the ensemble mean of the 14 models with computed sea surface temperatures). At the subregional scale, the LGM EAWM strengthened north of about 30°N but weakened south of this region in East Asia, which can be explained by changes in surface temperature. On the other hand, all of the 14 models chosen in this study consistently simulated a weaker than baseline East Asian summer (June-August) monsoon during the LGM, with an average weakening of 25%.

The welfare states in East Asia have been widely considered underdeveloped. Since the definition and measurements of social policy and the welfare state are subject to change depending on the specific historical, political and economic context, the welfare underdevelopment thesis deserves scrutiny. In Japan, Korea and Taiwan, agricultural protection and enterprise welfare, among others, have been surrogates of conventional welfare policies. As a way of critically engaging in the debate over the East Asian welfare model, this paper focuses on these two areas of surrogate social policy and explores their empirical basis with the OECD data on Japan and Korea. The result shows that surrogate social policy measures such as producer support estimates for agricultural protection and mandatory private social spending for enterprise welfare add up to make a difference between the East Asian countries and the other OECD members. This suggests a distinct political-economic model for East Asian social welfare. [ABSTRACT FROM PUBLISHER]

Introduction and Aims. Southeast and East Asia has become a global hub for methamphetamine production and trafficking over the past decade. This paper describes the rise of methamphetamine supply and to what extent use of the drug is occurring in the region. Method and Design. The current review uses data collected through the Drug Abuse Information Network for Asia and the Pacific (DAINAP) and other available sources to analyse retrospectively methamphetamine trends within Southeast and East Asia. Results. Southeast and East Asia has experienced a methamphetamine epidemic in the past decade which began around 1997 and peaked in 2000 - 2001. While the situation has since stabilised in many countries, methamphetamine trafficking and use are still increasing in parts of the Mekong region and there is evidence of large-scale manufacture in Cambodia, Indonesia, Malaysia and the Philippines. Methamphetamine is typically smoked or ingested, but injection of the drug is apparent. Conclusion. While the peak of the methamphetamine epidemic has passed in parts of Southeast and East Asia, attention is needed to minimise the potential consequences of spreading methamphetamine production, trafficking and use in the Mekong region and in the peninsular and archipelago of Southeast Asia.

Population aging is unique in Asia given the speed at which it is occurring and the immense social and economic changes that the region is experiencing at the same time. Compared to their Western counterparts, Asian governments have much less time to prepare for population aging. Asian countries that have traditionally relied on family-based support for older family members are worried that increased numbers of older adults may stress these family systems. At the same time, information concerning the effectiveness of formal programs for older adults is scarce. This paper reviews current research on informal support versus formal support of older adults in Southeast and East Asia, with a larger aim of assessing the current well-being of older Asians and suggesting areas of policy concern. Current research reveals that formal programs in the majority of Southeast and East Asian countries have very low coverage of today's older adults, and the figures for future generations are not that much higher. However, family support of older persons may not be deteriorating as predicted by modernization theory. Asian families continue to play a major role in supporting older members, thus policies should focus on enabling Asian families to provide this support. [ABSTRACT FROM AUTHOR]

This study investigates the impact of boreal winter–peaked La Niña on the following-summer precipitation in East Asia through intermediate sea surface temperature (SST) anomalies playing the role of relay in observation and numerical models. There are widespread dry conditions in both North and South China and wet conditions in coastal areas of central and eastern China. Such a pattern is mainly attributed to an anomalous low pressure over the western tropical Pacific and an anomalous anticyclone over northeast Asia. It is found that the delayed impact of La Niña on the East Asian climate is operated through intermediate SST anomalies—the Z-shape cold SST anomalies in the tropical North Pacific. There might be three ways for the SST anomalies to operate. First, they produce tropical atmospheric perturbations that can penetrate into the subtropical jet through the westerly trough over the northeast subtropical Pacific, the wave train being then excited along the jet. Second, perturbations created through the monsoon trough over the western Pacific can directly stimulate northward-propagating Rossby waves along the East Asian coast, mainly at low level. And third, perturbations over the tropical Atlantic–northwest Africa can also trigger downstream propagating waves along the subtropical jet. The observation effects of the intermediate SST anomalies and their possible impact mechanisms on atmospheric circulation are largely reproduced within numerical simulations performed with the Community Earth System Model.

This study first investigates the interannual variations in spring precipitation intraseasonal variability over southern China (SC). The results show that SC spring precipitation exhibits distinct intraseasonal variations with a period of 7–25 days. The first mode of 7–25-day precipitation intraseasonal variability (PIV) displays a monopole pattern over SC, and the PIV magnitude is largely determined by the upward motion intensity during intraseasonal precipitation events. Further analysis suggests that two atmospheric wave trains are observed during intraseasonal precipitation events, which propagate eastward from the North Atlantic along the northern and southern paths. In strong PIV years, the two wave trains can propagate to East Asia and show coordinated influences. The resultant low pressure to the west of SC causes strong upward motion and PIV over SC by bringing strong zonal vorticity and meridional temperature advection. In weak PIV years, the southern wave train can only propagate to the Bay of Bengal; therefore, the northern wave train plays a major role. The resultant low pressure is now over the upper to middle reaches of the Yangtze River, which causes relatively weak upward motion and PIV over SC by bringing weak meridional vorticity and temperature advection. Further analysis indicates that the sea surface temperature (SST) condition over the tropical Indian Ocean and the South China Sea is essential for southern wave train propagation. The warming SST over the regions can intensify westerlies to its north and consequently favors the propagation of the southern wave train to SC, eventually contributing to strong PIV over SC.

The relationship between the East Asian summer monsoon (EASM) and East Asian winter monsoon (EAWM) across time scales has been an interesting topic for decades. In this study, we quantitatively investigate the EASM–EAWM relationship at the obliquity time scales using a set of accelerated transient simulations. By comparing different indices defined with different variables, we find that the EASM and EAWM intensities are positively correlated under obliquity forcing. High obliquity leads to warmer summertime and cooler wintertime surface temperatures, with a stronger response observed over land than over the oceans. The warmer summertime and cooler wintertime temperature responses are accompanied by a strengthened Asian low in summer and Siberian high in winter, with enhanced southerlies in summer and northerlies in winter, indicating an enhanced EASM and EAWM. Modulated by ice sheet forcing, however, the evolution of the simulated EAWM shifts toward the ice sheet maximum, such that the circulation-based EASM–EAWM relationship in the realistically forced simulation exhibits a phase shift of approximately 11 kyr, closer to the phase between the composite δ18O and loess grain size in observations. Our results may have implications for better understanding the distinct changes in the proxy-based EASM–EAWM relationship before and after the rapid growth of global ice volume at around 3 Ma. Significance Statement: Studying the relationship between the EASM and EAWM can help us understand the characteristics and mechanisms of the regional climate in response to external forcings at different time scales. By investigating the EASM–EAWM relationship over the past 300 000 years, we find that, forced by obliquity variations, the EASM and EAWM are positively correlated at the obliquity time scales. The ice sheet forcing, meanwhile, also influences the circulation over East Asia and modulates the evolutionary phases between the EASM and EAWM. Our results highlight the importance of the combined impacts of orbital parameters and ice sheets on past climate changes over Asia. [ABSTRACT FROM AUTHOR]

With over one-third of East Asia's 1.7 billion people overweight or obese, mounting demographic pressure and burgeoning healthcare costs are forcing public health officials to grapple with the rising morbidity and mortality associated with obesity. However, the presence of metabolically healthy obesity, in which the short-term disease risks of diabetes and heart disease are low, represents a possible buffer for healthcare planning in East Asia. This narrative review analyzes the health risks from obesity through representative Japan- and China-specific analyses that take into account unique cultural, genetic, and other factors that drive obesity; the potential impact of metabolically healthy obesity on public health; and suggested non-surgical/non-pharmacological interventions to relieve pressure on the nationalized healthcare systems prevalent in the region. Such an emphasis on interventions to both delay obesity as well as potentially reverse metabolic syndrome could save millions of lives and billions of USD equivalents in healthcare throughout East Asia.

Both South Asia and East Asia are the most polluted regions of the world. Unlike East Asia, the aerosol optical depth (AOD) over South Asia keeps increasing for all recent years, which calls for more attention. This study investigates the impacts of anthropogenic emissions over South Asia on the downstream regional climate during spring with the Community Earth System Model 2 (CESM2). The model results suggest that South Asian pollutants have significant impacts on East Asian spring climate, and the impacts could be even larger than locally emitted aerosols. Two possible dynamical pathways (i.e., the northern and the southern pathways) bridging South Asian aerosol forcing and East Asian climate are proposed, and both ways are associated with the black carbon (BC)-induced climate feedbacks surrounding the Tibetan Plateau (TP). The northern pathway is mainly due to the TP warming induced by the BC snow darkening effect (SDE), which significantly reduces the surface air temperature (SAT) over northern East Asia. BC-induced TP warming increases the meridional thermal gradient and accelerates the midlatitude jet stream, which favors the cold-air advection over northern East Asia. The southern pathway is associated with the BC "elevated heat pump" hypothesis, which mainly affects the precipitation in southern East Asia. BC from South Asia accumulates near the south slope of TP, inducing an abnormal ascending motion near the Bay of Bengal. A compensating anomalous sinking motion is then forced in South China, which suppresses the precipitation there. A primary observational analysis is also performed to verify both dynamical pathways.

Coupled climate models project robust wintertime wetting trend over midlatitude East Asia under global warming scenarios, but the projected change in precipitation shows large intermodel uncertainty over subtropical East Asia from southern China to southwestern Japan. Based on an ensemble of climate models participating in CMIP6, this study shows that the weakened southern branch westerly jet (SWJ) on the southern side of Tibetan Plateau (TP) plays a key role in suppressing subtropical East Asian precipitation. The SWJ is deflected into southwesterly wind on the southeastern side of TP, bringing ascent and precipitation to subtropical East Asia primarily through isentropic gliding. As a result of the poleward and upward shift of the planetary-scale westerly jet under global warming, the SWJ becomes weaker and it acts to suppress subtropical East Asian precipitation by weakening the southwesterly wind and ascent. The SWJ-precipitation linkage also exists on interannual time scales, but the sensitivity of precipitation to interannual SWJ variability is systematically underestimated by the models compared with observation. The combined effects of the change in SWJ strength and the sensitivity of precipitation to SWJ explain about 40% of the intermodel spread of the projected precipitation changes. Observational constraint on the SWJ--precipitation relationship amplifies the projected drying trend and narrows the intermodel spread. It shows that the regional-averaged precipitation over subtropical East Asia decreases by 3.3% per degree of warming, and the amplitude of precipitation reduction over subtropical East Asia (southern China) is about 1.4 (3.4) times the raw projection.

There has been growing interest in the social-emotional development of children. However, the social-emotional development of children in Asia remains a knowledge gap. This systematic review identifies and summarizes existing studies on children's social-emotional development in Asia. We conducted a systematic review using the Guidelines for Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). We reviewed 45 studies that met the inclusion criteria, and they were from 12 Asian countries, primarily the East Asia region (China and Hong Kong). Most of the studies were cross-sectional in design (n = 28, 62.2%). Six themes emerged, including (a) social-emotional development (overall) (n = 24, 53.3%); (b) social competence (n = 7, 15.6%); (c) emotional development (n = 5, 11.1%); (d) social-emotional learning (n = 3, 6.7%); (e) problem behavior (n = 3, 6.7%); (f) self-regulation (n = 2, 4.4%); and (g) both social-emotional learning and problem behavior (n = 1, 2.2%). The findings highlighted the paucity of studies, the need for examining more diverse variables in a similar population, and the low quality of intervention studies in social-emotional research in Asia. Research gaps indicate the need for more social-emotional and ethnocultural studies in other Asian regions. Parent and teacher knowledge of children's social-emotional functioning should be examined more closely in future research. [ABSTRACT FROM AUTHOR]

To achieve a sustainable society and solve the problems caused by climate change and socioeconomic activities, it is necessary to monitor the spatial and temporal variability of ecosystem functions, services, and biodiversity at both regional and global scales. During the last decade, we have seen rapid and significant improvement in satellite and near‐surface remote‐sensing technologies. In this review, we describe how remote‐sensing observations are being used to effectively evaluate the spatial and temporal variability of land use and cover types and of plant phenology in East Asia. We discuss the current status, uncertainties, problems, and future perspectives for terrestrial ecosystem and biodiversity monitoring, and we address the multidisciplinary research by incorporating in situ and satellite observations for East Asia. Recent satellites with advanced optical sensors, such as MultiSpectral Instrument/Sentinel‐2A/2B, Advanced Himawari Imager/Himawari‐8, and PlanetScope, and satellites with synthetic aperture radar, such as Advanced Land Observing Satellite‐2, allow detailed monitoring of land use and cover type changes and plant phenology. These satellite sensors can provide images with high spatial (3–10 m) and high temporal (10 min to 5 days) resolution, at both large (≥1 km2) and small (<1 km2) scales. In particular, researchers are expected to develop discrimination techniques that will enable these advanced satellite technologies to detect evergreen broadleaf trees and ways to estimate the geographic distribution of leaf traits. We encourage more collaborations among ecologists, engineers, and remote‐sensing scientists to share their abundant knowledge and experience and thereby improve the monitoring capabilities.

During the winter and subsequent spring of an El Niño year, the East Asian marginal sea (EAMS) exhibits positive sea surface temperature anomalies (SSTAs) and fewer low clouds, while the western North Pacific experiences negative SSTAs. In this study, we suggest that the positive SSTAs in EAMS are maintained by a positive low cloud–SST feedback. In neutral winters and springs, the EAMS is covered by low clouds, which have a cooling effect on surface temperatures. During an El Niño year, a western North Pacific anomalous anticyclone is established, and along its northwestern flank, there are favorable conditions for convergence of moisture and weaker surface latent heat flux over the EAMS. Once a positive SSTA has been established, a further reduction of turbulent mixing results in less low cloud and enhanced solar heating of the ocean mixed layer; this reinforces and maintains both the positive SSTA and the lack of low cloud via a positive feedback mechanism. The concurrent increase of low cloud–SST feedback and anticyclone circulation strengths is evident in the coupled-model simulations from phase 6 of the Coupled Model Intercomparison Project. Furthermore, sensitivity experiments, performed with the atmospheric components of Community Earth System Model (CESM2), reveal that a positive SSTA helps to maintain the western North Pacific anomalous anticyclone. Four pacemaker-coupled experiments by CESM2, with sea surface temperature in the equatorial Pacific restored to the observational anomalies plus the model climatology and altered low cloud feedback over EAMS, suggest that the low cloud–SST feedback results in more than the maintenance of a positive SSTA over the EAMS: the positive feedback is also a previously overlooked mechanism for the maintenance of the western North Pacific anomalous anticyclone. Significance Statement: The East Asian marginal sea (EAMS) and western North Pacific are important areas that bridge El Niño and the climate of East Asia. Unlike the cold sea surface temperature anomaly (SSTA) over the western North Pacific during El Niño, the positive SSTA over EAMS, which is covered by winter low cloud, has received less attention. We suggest that a "low cloud–SST" feedback—namely, one in which decreasing low-level clouds allows more sunlight to strike the ocean surface and favors higher SST—maintains the positive SSTA over EAMS. We also configure a widely used atmospheric model with a set of preset SSTA patterns that mimic different climate patterns. Our experiments with different climate patterns and CMIP6 historical runs show that the low cloud–SST feedback (through the positive SSTA) is a possible supplementary mechanism for reinforcing the WNP anomalous anticyclone.

Occult Hepatitis B virus infection (OBI) is of great significance to the transmission of Hepatitis B virus (HBV) and the evolution of the patient's clinical outcome. We conducted a systematic review and meta-analysis to estimate the prevalence of OBI in Asia. Literature search was conducted in PubMed, Cochrane Library database, Web of Science and Embase with the keywords of 'Hepatitis B virus', 'occult infection', 'prevalence'. 70 studies were included in the meta-analysis. Meta-analysis was performed using random-effects models to calculate the pooled prevalence of OBI and 95% confidence interval (CI). The data were analyzed in R 4.1.2. The overall prevalence of OBI was 4% (95%CI: 0.03–0.06) in Asia. Subgroup analysis based on geographic region showed a prevalence of 3% (95%CI 0.02–0.06) in East Asia, 9% (95%CI 0.05–0.15) in West Asia, 3% (95%CI 0.01–0.11) in Southern Asia and 9% (95%CI 0.05–0.15) in Southeast Asia. Subgroup analysis demonstrated a prevalence of 1% (95%CI 0.00–0.02) in general population, 5% (95%CI: 0.03–0.08) in high-risk population, 9% (95%CI: 0.03–0.22) in the human immunodeficiency virus (HIV)-infected patient, 18% (95%CI: 0.09–0.32) in the hepatopathy patients. Based on the meta-analysis of the prevalence of OBI in different populations, we concluded that the prevalence of OBI in the high-risk population, hepatopathy patients, and HIV-infected patients was higher than that in the general population. A systematic review showed that OBI was associated with disease progression and prognosis. Therefore, these populations should be routinely screened for OBI and promptly intervened to avoid promoting disease progression. [ABSTRACT FROM AUTHOR]

Consistent with the 2030 United Nations Sustainable Development Goal 8 (implement policies to promote sustainable tourism), 9 (provide infrastructure for universal and affordable access to the Internet), and 17 (promote international trade), this study interrogates the services trade-ICT nexus on sustainable tourism in Asia. Using an unbalanced panel data on 44 East Asia and Pacific and South Asian countries from 2010 to 2019 it probes the discourse using tourism receipts, trade in services, and four ICT indicators (mobile phones, Internet users, fixed broadband, and secured internet servers). In broader terms, this study addresses two questions: whether ICT usage and services trade individually impact tourism and if the interaction of ICT influences or erodes the impact of services trade on tourism? Deploying the PSCC-LSDV and MM-QR robustness techniques, findings reveal that (1) services trade and ICT individually promote tourism; (2) the negative interaction effect of services trade and ICT is not sufficient to erode the enhancing-impact of services trade; (3) effect of services trade and ICT usage and their interaction significantly differ across the sub-regions; and (4) effect of services trade and ICT usage is heterogeneous across the quantiles. Policy recommendations are discussed. [ABSTRACT FROM AUTHOR]

This study examines the causal relationship between the Internet and economic factors in Asian economies between 1997 and 2017. The economic factors consist of gross domestic product (GDP), foreign direct investment (FDI), imports, and exports. A comparative analysis of East, South, and Western Asia was conducted using a panel vector autoregressive model. The findings show bidirectional causality between FDI and Internet use in South Asia, unidirectional causality from Internet use to FDI in East Asia, and unidirectional causality from FDI to Internet use in Western Asia. Moreover, the findings indicate unidirectional causality from exports to Internet use in East Asia and unidirectional causality from Internet use to exports in South Asia, but no impact in Western Asia. Finally, the results show unidirectional causality from Internet use to GDP in Western Asia. As these results suggest that Internet use has boosted economic performance in Asia, policy makers in the region should improve Internet use with a focus on economic growth, improving transaction efficiency, and facilitating foreign investment.

The why and the how of knowledge production are examined in the case of the transnational cooperation between the directors of observatories in the Far East who drew up unified typhoon-warning codes in the period 1900–1939. The why is prompted by the socioeconomic interests of the local chambers of commerce and international telegraphic companies, although this urge has the favourable wind of Far Eastern meteorologists' ideology of voluntarist internationalism. The how entails the persistent pursuit of consensus (on ends rather than means) in international meetings where non-binding resolutions on codes and procedures are adopted. The outcome is the co-production of standardised knowledge, that is, the development of a series of processes and practices that co-produce both knowledge and ideas about the social order in a force field characterised by negotiations and power struggles.

This paper applies fuzzy clustering techniques to developed and emerging economies in East Asia, in order to arrive at an identification of potential subgroups of economies for monetary union. The statistical criteria employed is the one suggested by the Optimal Currency Areas theory, and the period examined includes the recent global crisis. Three alternative monetary anchor countries are proposed, namely the United States, Japan and China, and hence, to an extent, the analysis does indicate the relative importance of the three world's largest economies to East Asia. Due to the endogeneity of the convergence criteria in the eurozone, founding member states of EMU are used as a point of reference for East Asia to indicate the level of preparedness for monetary union in this region. Findings indicate that Singapore and Hong Kong are relatively prepared for integration. In addition, results do also signify the dominance of Japan despite the prevalence of the dollar standard in the region. [ABSTRACT FROM AUTHOR]

This paper documents the effect of corporate governance mechanisms on the dispersion in analysts' recommendations in Asian emerging markets. Using a large dataset of analyst recommendations, we document a significantly higher dispersion in analysts' recommendations during the pre-crisis period (poor governance regime) relative to the post-crisis period (better governance regime). We argue that higher dispersion in analysts' recommendations was due to ineffective governance mechanisms prevailing during the pre-crisis period. However, as governance mechanisms improved, reduction in information asymmetries resulted in convergence of analysts' information, thereby lowering the dispersion in analysts' recommendations during the post-crisis period. Consistent with our arguments, our results show that corporate governance mechanisms can explain the bulk of difference in dispersion between the two periods. This study adds to the debate on effectiveness of corporate governance reforms in Asian emerging markets. Our results, overwhelmingly, indicate the success of governance reforms initiated after the Asian financial crisis of 1997-1998. [ABSTRACT FROM AUTHOR]

East Asian countries are booming with both technological and demographic advances. They have tradition-ally developed their economies by being licensed foreign Information and Communications Technology (ICT) standards and using them to develop their home market and to export products. This paper proposes that East Asian countries should start to develop a leadership role in global ICT standardizations, even though their focuses are currently still primarily on developments in their own nations.

In recent years international trends towards teacher empowerment and leadership have gained increased attraction in East Asia's education policy and practice. Yet, as scholars have noted, the values underlying these practices often conflict with traditional cultural norms of East Asian societies which stress hierarchical and status differences. This study explored the efficacy of an approach to developing distributed curriculum leadership among school teachers. The research employs discourse analysis of video-taped meetings of teachers in a mathematics curriculum development team in order to explore the leadership and teacher learning. The results provide initial support for strengthening school-level capacity for teacher leadership as a means of fostering teacher learning in East Asian schools. Implications include the need for incorporating programmes that build leadership and team development into more general staff development for teachers. [ABSTRACT FROM PUBLISHER]
