- Abstract
In the past decade, hundreds of impact evaluation studies have measured the learning outcomes of education interventions in developing countries. The impact magnitudes are often reported in terms of "standard deviations," making them difficult to communicate to policy makers beyond education specialists. This paper proposes two approaches to demonstrate the effectiveness of learning interventions, one in "equivalent years of schooling" and another in the net present value of potential increased lifetime earnings. The results show that in a sample of low- and middle-income countries, one standard deviation gain in literacy skill is associated with between 4.7 and 6.8 additional years of schooling, depending on the estimation method. In other words, over the course of a business-as-usual school year, students learn between 0.15 and 0.21 standard deviation of literacy ability. Using that metric to translate the impact of interventions, a median structured pedagogy intervention increases learning by the equivalent of between 0.6 and 0.9 year of business-as-usual schooling. The results further show that even modest gains in standard deviations of learning--if sustained over time--may have sizeable impacts on individual earnings and poverty reduction, and that conversion into a non-education metric should help policy makers and non-specialists better understand the potential benefits of increased learning.

Under economic globalization, countries are linked through trade and investments. This economic interdependence creates vulnerabilities. The indirect vulnerability induced by interdependent networks of trade and investments can put a country's economy at risk, but this risk has yet to be systematically quantified and investigated. In this paper, we developed the novel Potential Indirect Vulnerability Index (PIVI) to capture how interdependencies between networks of trade and foreign direct investment (FDI) may induce economic vulnerabilities. The model consisted of three main components: a target country (the importer of goods), an investing country (the exporter of FDI), and the intermediary countries that export commodities to the target country and receive FDI from the investing country, serving as conduits of the vulnerabilities caused indirectly by the investing country. The PIVI quantifies the indirect vulnerabilities based on the product of two fractions: 1) the dependency of the target country on commodities from each intermediary country; and 2) the dependency of each intermediary country on FDI from the investing country. We demonstrated the utility of PIVI by examining the US economy's vulnerability to China using 2019 trade and FDI data. Several Asian countries and a mix of agricultural products and raw materials were identified as conduits through which China could potentially influence the US economy. Vietnam was a sizeable risk because, while it has been a primary source of many US imports, it also received about 30% of its FDI from China. The US policy makers might opt to increase diversity in trade partners or to promote investment in countries such as Vietnam. We also applied the PIVI analysis to critical minerals, identifying cobalt, tungsten, and copper as the most vulnerability-inducing among them. PIVI is a flexible metric than can be aggregated and modified to provide a more nuanced and focused assessment of an economy's vulnerability. [ABSTRACT FROM AUTHOR]

Vietnam's agricultural exports to China have remained strong, with the country maintaining its position as the top destination for Agri-products. This article primarily utilizes the Revealed Comparative Advantage (RCA) Index, and Trade Complementarity (TC) index to examine the trade comparative advantage, and the complementary of twenty major agricultural products between China and Vietnam from 2012 to 2021. The study results showed that Vietnam and China frequently exchange agricultural products. Vietnam has more stronger competitiveness than China in terms of agricultural products. China's exports to Vietnam were highly complementary to Vietnam's imports in category 0 whiles Vietnam's exports to China showed strong complementarity with China's imports in category 2. This paper analyzes the complementarity and comparative advantages of agricultural trade between China and Vietnam, and proposes informed suggestions for policy-making to promote agricultural trade between the countries. The proposed suggestions aim to expand agricultural trade between the two countries, reduce the trade imbalance, and achieve mutual benefit and win-win results. [ABSTRACT FROM AUTHOR]

Simple Summary: In response to the quantitative demand for the practical deployment of applications and the need to enhance the detection accuracy of wildlife in complex field environments in southwest China and neighboring regions, we have refined the wildlife detection algorithm based on re-parameterized convolution. This refinement is specifically targeted at addressing the challenges posed by the low quality of wildlife images captured by camera traps and the limitations of traditional object detection algorithms in feature extraction capability. To address these issues, we have introduced a series of improvement schemes. As a result of these enhancements, there has been a noteworthy improvement in both the accuracy of wildlife detection and the speed of model inference. This advancement offers a convenient and efficient method for the preliminary detection in the context of automated wildlife monitoring. To autonomously detect wildlife images captured by camera traps on a platform with limited resources and address challenges such as filtering out photos without optimal objects, as well as classifying and localizing species in photos with objects, we introduce a specialized wildlife object detector tailored for camera traps. This detector is developed using a dataset acquired by the Saola Working Group (SWG) through camera traps deployed in Vietnam and Laos. Utilizing the YOLOv6-N object detection algorithm as its foundation, the detector is enhanced by a tailored optimizer for improved model performance. We deliberately introduce asymmetric convolutional branches to enhance the feature characterization capability of the Backbone network. Additionally, we streamline the Neck and use CIoU loss to improve detection performance. For quantitative deployment, we refine the RepOptimizer to train a pure VGG-style network. Experimental results demonstrate that our proposed method empowers the model to achieve an 88.3% detection accuracy on the wildlife dataset in this paper. This accuracy is 3.1% higher than YOLOv6-N, and surpasses YOLOv7-T and YOLOv8-N by 5.5% and 2.8%, respectively. The model consistently maintains its detection performance even after quantization to the INT8 precision, achieving an inference speed of only 6.15 ms for a single image on the NVIDIA Jetson Xavier NX device. The improvements we introduce excel in tasks related to wildlife image recognition and object localization captured by camera traps, providing practical solutions to enhance wildlife monitoring and facilitate efficient data acquisition. Our current work represents a significant stride toward a fully automated animal observation system in real-time in-field applications. [ABSTRACT FROM AUTHOR]

The surprising resilience of current communist states towards democratic opening and a mainstream neoliberal economic 'way-of-life' in the past did not hamper their economic performances and development perspectives as much as we would expect. In the countries that are one-party states, in which the institutions of the ruling party and the state have become intertwined, ostensibly arguing for political and economic equality, still maintaining a firm control over the economic resources, we could expect economic relationships that are au contraire modern economic trends. However, China for example, a supposedly communist economy, with its breathtaking socio-economic progress, elusively ignores mainstream economic vocation, progressively advancing towards establishing itself as a sacrosanct economic force. In that manner, the goal of this paper is to (1) evaluate the dynamics of relevant macroeconomic variables in three current communist states (China, Laos and Vietnam) in order to (2) expose possible deviations to modern capitalist trends as well as to (3) provide relevant information that can serve as a guideline for macro policies. For that purpose, we analyzed the relationship between the GDP, price, money and the exchange rate by using VAR modeling. Results revealed coherent macroeconomic dynamics with a causality that is in accordance to a common capitalist economic framework. [ABSTRACT FROM AUTHOR]

Background: The situation of the COVID-19 outbreak in the border areas of China and Vietnam is complex, and its progress may affect the willingness of urban and rural residents to receive the vaccine. Objective: This study aims to understand the influence of the COVID-19 epidemic situation on the willingness of urban and rural residents in China-Vietnam border areas to get vaccinated and the factors that affect the vaccinations. Methods: A cross-sectional survey was conducted in Hani-Yi Autonomous Prefecture of Honghe, a border area between China and Vietnam, using online and paper questionnaires from April 1 to June 4, 2021. A total of 8849 valid questionnaires were surveyed to compare the differences in the willingness of urban and rural residents to receive the COVID-19 vaccine. Single factor analysis and multivariate logistic regression analysis were used to explore the influence of the epidemic situation on the willingness to be vaccinated. Results: In the border areas between China and Vietnam in Yunnan Province, both urban and rural residents had a high willingness (> 90%) to receive the COVID-19 vaccination, with a higher level of willingness in urban than in rural areas and a higher willingness among residents aged ≥ 56 years. Rural residents mainly concerned about the vaccination were different from urban residents (p< 0.05). About 54.8% of urban respondents and 59.2% of rural respondents indicated that their willingness to get COVID-19 vaccine would be affected by new COVID-19 cases. Respondents who were divorced, had an occupation other than farming, had contraindications to vaccination, were concerned about the safety of vaccines and worried about virus mutation, thought that the epidemic situation would not affect their willingness to get vaccinated (p< 0.05). Conclusion: The prevention and control of epidemics in border areas is of considerable importance. It is necessary to conduct targeted health education and vaccine knowledge popularization among urban and rural residents to increase the vaccination rate and consolidate the epidemic prevention and control at the border.

The changing population age structure has a significant influence on the economy, society, and numerous other aspects of a country. This paper has innovatively applied the method of compositional data forecasting for the prediction of population age changes of the young (aged 0–14), the middle-aged (aged 15–64), and the elderly (aged older than 65) in China, India, and Vietnam by 2030 based on data from 1960 to 2016. To select the best-suited forecasting model, an array of data transformation approaches and forecasting models have been extensively employed, and a large number of comparisons have been made between the aforementioned methods. The best-suited model for each country is identified considering the root mean squared error and mean absolute percent error values from the compositional data. As noted in this study, first and foremost, it is predicted that by the year 2030, China will witness the disappearance of population dividend and get mired in an aging problem far more severe than that of India or Vietnam. Second, Vietnam’s trend of change in population age structure resembles that of China, but the country will sustain its good health as a whole. Finally, the working population of India demonstrates a strong rising trend, indicating that the age structure of the Indian population still remains relatively “young”. Meanwhile, the continuous rise in the proportion of elderly population and the gradual leveling off growth of the young population have nevertheless become serious problems in the world. The present paper attempts to offer crucial insights into the Asian population size, labor market and urbanization, and, moreover, provides suggestions for a sustainable global demographic development.

- Abstract
The various possibilities that social media offers to language learners and teachers have long been recognized by researchers within the field of language instruction, and many studies have been carried out in an attempt to address and unpack its potential contributions. This paper aims to review such research on the use of mainstream social media in language teaching and learning published in "Computer Assisted Language Learning," a top tier (i.e., Q1) journal indexed in major citation index systems (e.g., Arts & Humanities Citation Index, the Social Sciences Citation Index and Scopus), between the years 2016-2020 inclusive. For the purposes of the study, a total of 23 articles that meet the selection criteria is reviewed and presented in five sections. The first section deals with the majority of the articles, which are found to be on the use of social networking in language teaching and learning. In the following sections, studies on the use of videoconferencing, wikis, blogging and forums are discussed. Collectively, the studies reviewed in this paper outline a critical role for the use of social media in language instruction and the study aims to provide valuable insights for researchers, teachers and learners.

Artieda, Gemma and Clements, Bindi
- Abstract
Wall Street English has built online activities that allow students to record phrases and receive word-level Automatic Speech Recognition (ASR) driven pronunciation feedback. Students in language centres in China, Vietnam, Saudi Arabia, and Italy (N=2,867) used ASR-Computer Assisted Language Learning (CALL) activities, and some (N=482) completed a questionnaire. A high number of students reported that ASR-CALL activities helped them to improve their pronunciation. However, the study found remarkable differences in usage of product features across countries, with students from Vietnam and China using more retries than Saudi Arabia, and students from Italy using the fewest retries. Students from China, Vietnam, and Saudi Arabia more frequently listened to model audios than students from Italy. A series of Kruskal-Wallis tests revealed significant group differences between dominant L1 and students' beliefs and perceptions using ASR, and between age groups and students' beliefs and perceptions using ASR. This study points to the importance of considering regional differences, and suggests that learner engagement may depend not only on the effectiveness of the technology, but also on learner beliefs and perceptions.

The Socialist Republic of Vietnam (SRV) and the People's Republic of China (PRC) had been close-knit allies since the the formation of the two states. However, they gradually moved apart in approaches towards regional and international affairs in the late 1960s and 1970s. This paper offers an account for the deterioration of Sino-Vietnamese relations in the 1970s. It is original in the sense that it focuses on exploring the perceptions of Vietnam and China that led to the competition for alliances, which has not been fully addressed in existing literature. This research employs the balance of threat theory in international relations - which argues that states commonly pursue an alliance strategy to balance against perceived threats - as the primary analytical framework to analyse primary and secondary sources and historical documents in Sino-Vietnamese relations. This study's main finding is that the different perceptions of threats in China and Vietnam has led the two countries to pursue balancing strategies to counter these threats. Such balancing acts led to a situation of security dilemma and it eventually ended up with a period of turbulent bilateral relations. [ABSTRACT FROM AUTHOR]

China and Vietnam have achieved remarkable economic growth since the reforms and opening of their economies (China with its economic reform and opening in 1978 and Vietnam with its economic renovation in 1986). Through the reform process, until now, the two countries have achieved remarkable achievements in economic growth. It is thus necessary to mention the role and contribution of the private sector in each economy. This article aims to analyze and compare the Chinese and Vietnamese policies toward the private sector and roles played by this sector in each economy since these two countries conducted reform and opened their economy until the present. From this comparison, we hope to find out the implications for Vietnam in developing the private sector. The findings of this paper are: (1) in general, China and Vietnam were similar in directions and policy toward private sector development since their launching of economic reform and renovation, respectively, (2) the private sector has contributed to the development of each economy, (3) the contribution of the private sector to the economy in China is much more than the case of Vietnam, especially in export, R&D and transformation of industrial structure.

Background The rising incidence of thyroid cancer (TC) has generated growing concern globally; yet there are no studies examining whether this incidence was followed by a rise in related mortality. We aimed to comprehensively quantify current trends and future projections of TC incidence and mortality, and to explore the association between the TC burden and socioeconomic inequality in different income strata. Methods We obtained incidence and mortality data on TC and population from the 2019 Global Burden of Disease (GBD) study and the United Nations' World Population Prospects 2022. We applied an age-period-cohort (APC) model to estimate the overall annual percentage change (net drift) and age, period, and cohort effects from 1990 to 2019, and also constructed a Bayesian APC model to predict the TC burden through 2030. Results Over a third of global TC cases belonged to the high-income group. From 1990 to 2019, net drifts of TC incidence were >0 in all income groups, while a modest reduction (net drift <0) in mortality was observed in most income groups, except for the lower-middle-income group. Unfavourable age, period, and cohort effects were most notable in Vietnam, China, and Korea. The age-standardised incidence rate (ASIR) is predicted to increase whereas the age-standardized mortality rate (ASMR) is expected to decrease globally between 2020 and 2030, with geographic heterogeneity being detected across income groups. We observed a positive correlation between ASIR and universal health coverage index and health worker density, but a negative one between ASMR and the two indicators, primarily in upper-middle-income and high-income countries. Conclusions Opposite patterns in incidence and mortality of TC raise concerns about overdiagnosis, particularly in upper-middle-income and high-income countries. Discrepancies in the distribution of health service accessibility, including diagnostic techniques and therapeutic care, should be addressed by narrowing health inequalities in the TC burden across countries.

- Abstract
Emotional and cultural intelligence are very important for foreign students during cross-cultural adjustment. Asian students from China, Vietnam, South Korea and Mongolia face different problems during their stay in People's Friendship University of Russia (RUDN University). In this intercultural context of living and studying they learn to communicate and interpret facial expressions not only of Russian people, but also students from all over the world. The main purpose of this study was to investigate differences in Emotional and cultural intelligence among Asian students from China, Vietnam, South Korea and Mongolia, who study in Russia. We used two questionnaires: Emotional Intelligence Test developed by D.V. Lusin and Cultural Intelligence Scale developed by S.Ang et al. We conducted Kruskal-Wallis H-test, Mann-Whitney U-test and Spearman's rho test. Results indicate the following. Vietnamese students have the highest level of cultural intelligence and its metacognitive, cognitive and behavioral dimensions and lowest level of emotional intelligence namely expression and emotion control, managing their own emotions and intrapersonal emotional intelligence. Chinese students have the highest level of emotional intelligence and all its aspects. Mongolian and Chinese students have the highest level of emotion control. Mongolian students have lowest level of cultural intelligence namely in its metacognitive, and behavioral dimensions. South Korean students have the lowest level of cultural intelligence motivation dimension. Emotional intelligence has negative weak correlation with cognitive dimension of cultural intelligence. Cultural intelligence correlates positively with understanding others emotions, emotion control, interpersonal emotional intelligence and negatively with expression control, intrapersonal emotional intelligence, emotion control.

Ecologists have generally concluded that species distributions are not random (e.g. aggregate), based on single‐species studies that applied single‐species–based statistical methods, like the negative binomial model. Although it is common knowledge that some specific species in an ecological community present aggregate distributions, this does not necessarily imply that the entire community presents an aggregate distribution. Studying community‐level distributional aggregation patterns requires different statistical methods.Herein, by utilizing a novel conspecific‐encounter index derived from a multiple species Markov transition model that accounts for the non‐independent sampling of consecutive individuals along line transects, we were able to show that tree assemblages in tropical forest ecosystems can present a strong signal of extensive distributional interspersion.This interesting result is not unexpected, given the fact that neighbouring tree individuals in highly diverse tropical forests are usually of different species, resulting in strong niche packing or interspersed patterns. In contrast, for the amphibian assemblages surveyed from southwestern China and central‐south Vietnam, the conspecific‐encounter index was found to be consistently high, implying that amphibian communities tend to be highly aggregate in space.Conclusively, using the conspecific‐encounter index derived from the Markov non‐independent sampling model, we provide a legible definition of community‐level distributional aggregation as an interspersed or cluster‐like distribution of different species. This definition is not idiosyncratic, as it is coincident with the definition of the contagion index used in landscape ecology. To this end, the model used in this paper establishes a framework explicitly linking community ecology and landscape ecology from a multi‐object perspective. [ABSTRACT FROM AUTHOR]

In this paper, the complete chloroplast genome (cpDNA) and basic annotated information were reported and its phylogenetic relationship with other species in Magnoliaceae was analyzed. The size of chloroplast genome of M. balansae var. balansae is 160,134 bp, which exhibited a typical quadripartite structure comprising a large single-copy (LSC) region of 88,161 bp and a small single-copy (SSC) region of 18,845 bp separated by a pair identical inverted repeat regions (IRs) of 26,564 bp each. The chloroplast genome contains 131 genes, including 86 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes and 8 ribosomal RNA (rRNA) genes. The phylogenetic analysis indicated that M. balansae var. balansae is most affinal to M. montana and they form a nomophyletic group with other 14 Michelia species. This Michelia clade is sister to the Aromadendron clade with high support. All genera mentioned in this analysis are nomophyletic under the system of Magnoliaceae by Sima and Lu.

Background: Research capacity is scarce in low- and middle-income country (LMIC) settings. Social determinants of health research (SDH) is an area in which research capacity is lacking, particularly in Asian countries. SDH research can support health decision-makers, inform policy and thereby improve the overall health and wellbeing of the population. In order to continue building this capacity, we need to know to what extent training exists and how challenges could be addressed from the perspective of students and staff. This paper aims to describe the challenges involved in training scholars to undertake research on the SDH in four Asian countries - China, India, Oman and Vietnam.Methods: In-depth interviews were conducted with research scholars, research supervisors and principal investigators (n = 13) at ARCADE partner institutions, which included eight universities and research institutes. In addition, structured questionnaires (n = 70) were used to collect quantitative data relating to the courses available, teaching and supervisory capacity, and related issues for students being trained in research on SDH. Simple descriptive statistics were calculated from the quantitative data and thematic analysis applied to the qualitative data.Results: We identified a general lack of training courses focusing on SDH. Added to this, PhD students studying related areas reported inadequate supervision, with limited time allocated to meetings and poor interpersonal communication. Supervisors cited interpersonal communication problems and student lack of skills to perform high quality research as challenges to research training. Further challenges reported included a lack of research funding to include SDH-related topics. Finally, it was suggested that there was a need for institutions to define clear and appropriate standards regarding admission and supervision of students to higher education programs awarding doctoral degrees.Conclusions: There are gaps in training for research on the SDH at the surveyed universities and research institutes, which are likely to also be present in other Asian countries and their higher education institutions. Some of the barriers to high quality research and research training can be addressed by improved training for supervisors, clearly defined standards of supervision, finances for student stipends, and increased use of information and communication technology to increase access to teaching materials. Increased opportunities for online learning could be provided. [ABSTRACT FROM AUTHOR]- Published

As a less-powerful state threatened by a rising China in both security and economic domains irrespective of increasing economic cooperation and sharing a border and political affinity with China, Vietnam is expected to warmly welcome the United States (US) -led Indo-Pacific Strategy (IPS) The country, nonetheless, has remained low-key in responding to the IPS. The article argues that Hanoi is truly interested in a regional rules-based order promoted in the IPS, but it has proposed a hedging response to this strategy through cautious statements and limited engagement in into this strategy. Vietnam’s hedging response to the IPS is framed by its post-Doi Moi foreign policy of independence, self-reliance, multilateralisation, and diversification. The year 2023 marks a milestone in bilateral relations between the US and Vietnam as both states upgraded their diplomatic relations to comprehensive strategic partnership which is the highest level in Vietnamese diplomatic ranking. This may become a favourable catalyst for further cooperation between Washington and Hanoi under the IPS within the context of a rising China. [ABSTRACT FROM AUTHOR]

We examined the effects of the trade war on US wooden furniture imports by product category (kitchen, bedroom, other) and exporting source (e.g., China, European Union, Vietnam) using a two‐stage demand procedure and general nested demand framework. There were significant competitive relationships across exporting countries. However, when both trade creation and diversion were considered, competitive relationships either diminished or became complementary. Consequently, elimination of the trade‐war tariffs would increase imports from China but would also benefit countries like Vietnam. However, results indicate that imports from China would still be significantly less than pretrade war levels if the tariffs are eliminated. [ABSTRACT FROM AUTHOR]

Background: Geological movements and climatic fluctuations stand as pivotal catalysts driving speciation and phylogenetic evolution. The genus Polyspora Sweet (Theaceae), prominently found across the Malay Archipelagos and Indochina Peninsula in tropical Asia, exhibits its northernmost distribution in China. In this study, we investigated the evolutionary and biogeographical history of the genus Polyspora in China, shedding light on the mechanisms by which these species respond to ancient geological and climatic fluctuations. Methods: Phylogenetic relationships of 32 representative species of Theaceae were reconstructed based on the chloroplast genome and ribosome 18-26 S rRNA datasets. Species divergence time was estimated using molecular clock and five fossil calibration. The phylogeography and population genetics in 379 individuals from 32 populations of eight species were analyzed using chloroplast gene sequences (trnH-psbA, rpoB-trnC and petN-psbM), revealing the glacial refugia of each species, and exploring the causes of the phylogeographic patterns. Results: We found that Chinese Polyspora species diverged in the middle Miocene, showing a tropical-subtropical divergence order. A total of 52 haplotypes were identified by the combined chloroplast sequences. Chinese Polyspora exhibited a distinct phylogeographical structure, which could be divided into two clades and eight genealogical subdivisions. The divergence between the two clades occurred approximately 20.67 Ma. Analysis of molecular variance revealed that the genetic variation mainly occurred between species (77.91%). At the species level, Polyspora axillaris consists of three lineages, while P. speciosa had two lineages. The major lineages of Chinese Polyspora diverged between 12 and 15 Ma during the middle to late Miocene. The peak period of haplotype differentiation in each species occurred around the transition from the last interglacial to the last glacial period, approximately 6 Ma ago. Conclusion: The primary geographical distribution pattern of Chinese Polyspora was established prior to the last glacial maximum, and the population historical dynamics were relatively stable. The geological and climatic turbulence during the Quaternary glacial period had minimal impact on the distribution pattern of the genus. The genus coped with Quaternary climate turbulence by glacial in situ survival in multiple refuges. The Sino-Vietnam border and Nanling corridor might be the genetic mixing center of Polyspora.

[Display omitted] • Nam Xe REE deposit is of hydrothermal origin. • Nam Xe REE deposit has two episodes of REE mineralization at 45–44 Ma and 35–31 Ma. • Two episodes of REE mineralization coincide with the main- and late-collisional periods of the India-Asia convergence, respectively. Carbonatite-related rare-earth element (REE) deposits are developed in large areas of southwestern China and northwestern Vietnam on the SW margin of the South China block. The ages of REE deposits and their host carbonatite-alkaline rocks in southwestern China have been tightly constrained in the 35–10 Ma interval, but those in northwestern Vietnam remain poorly understood. In this paper, we present new Th–Pb dating results to constrain the timing of mineralization of the Nam Xe REE deposit in northwestern Vietnam, and to reveal its possible relationship to the well-studied REE deposits in southwestern China. The Nam Xe deposit consists of three types of REE ores: Type 1, fine-grained disseminated ores; Type 2, coarse-grained, taxitic ores; and Type 3, REE veinlets. The mineral assemblages and their close relations to hydrothermal alteration, combined with the trace element patterns of the ore minerals, indicate a hydrothermal origin for all the three ore types. Laser ablation-inductively coupled plasma-mass spectrometry Th–Pb dating of monazite yielded weighted-mean Th–Pb ages of 45–44 Ma for type 1 ores and 35–32 Ma for type 2 and 3 varieties, whereas the LA-ICPMS dating of bastnäsite has ages of 35–31 Ma for types 2 and 3, revealing two REE mineralization events at 45–44 and 35–31 Ma in the Nam Xe deposit. The age of type 1 ores overlaps the main-collision period of India-Asia collisional orogeny (65–41 Ma) which confirms carbonatite-related REE mineralization could form in the main-collisional geological setting. The ages of types 2 and 3 ores are consistent with those of the Mianning–Dechang REE metallogenic belt in southwestern China that formed under a late-collision extensional setting (40–26 Ma). Combined with existing geochronological data, results presented here suggest that the Nam Xe REE deposit formed both in the main- and late-collisional settings and represents the southern extension of the Mianning–Dechang REE metallogenic belt.

The cao vit gibbon (Nomascus nasutus) is one of the rarest primates on Earth and now only survives in a single forest patch of less than 5000 ha on the Vietnam–China border. Accurate monitoring of the last remaining population is critical to inform ongoing conservation interventions and track conservation success over time. However, traditional methods for monitoring gibbons, involving triangulation of groups from their songs, are inherently subjective and likely subject to considerable measurement errors. To overcome this, we aimed to use 'vocal fingerprinting' to distinguish the different singing males in the population. During the 2021 population survey, we complemented the traditional observations made by survey teams with a concurrent passive acoustic monitoring array. Counts of gibbon group sizes were also assisted with a UAV-mounted thermal camera. After identifying eight family groups in the acoustic data and incorporating long-term data, we estimate that the population was comprised of 74 individuals in 11 family groups, which is 38% smaller than previously thought. We have no evidence that the population has declined—indeed it appears to be growing, with new groups having formed in recent years—and the difference is instead due to double-counting of groups in previous surveys employing the triangulation method. Indeed, using spatially explicit capture-recapture modelling, we uncovered substantial measurement error in the bearings and distances from field teams. We also applied semi- and fully-automatic approaches to clustering the male calls into groups, finding no evidence that we had missed any males with the manual approach. Given the very small size of the population, conservation actions are now even more urgent, in particular habitat restoration to allow the population to expand. Our new population estimate now serves as a more robust basis for informing management actions and tracking conservation success over time. [ABSTRACT FROM AUTHOR]

In the past few decades, with the rapid economic development of China and Vietnam, the marine ecological environment of Beibu Gulf is facing increasing pressure. To understand the impact of anthropogenic inputs on marine ecology, high-performance liquid chromatography (HPLC) was used to study phytoplankton in this paper. We examined the influence of anthropogenic inputs on phytoplankton biomass and community structure in a subtropical estuary. Anthropogenic inputs had significantly increased the nutrient concentration in the estuary between 2010 and 2015. We observed that phosphorus limitation has been greatly relieved in 2015. However, the biomass of dominant phytoplankton was lower in 2015 than in 2010, possibly due to the expansion of oyster farming in the estuary. The coverage of oyster rafts was estimated to be 26.3 km
2 . The presence of dense oysters may significantly reduce the phytoplankton biomass. The proportion of Diatoms decreased while some nano- and pico-phytoplankton (like Cryptophytes and Prasinophytes) increased, which indicated that oysters changed not only the biomass but also the size of phytoplankton communities. This study improved our understanding of anthropogenic inputs on phytoplankton communities in subtropical estuary. [ABSTRACT FROM AUTHOR]- Published

Purpose: This study aims to investigate the supplier selection criteria, relationship quality and level of collaboration in Asian food businesses, while also examining the link between these practices and business performance. The research focusses on food manufacturing and exporting companies in two emerging economies, China and Vietnam. Design/methodology/approach: Food manufacturing and exporting companies in two emerging economies – China and Vietnam were surveyed and analysed to extract factors that reflect supplier management and business performance along with their relationship by factor analysis and hierarchical regression. Then, a two-step cluster analysis was applied to identify clusters based on supplier management and explore how different business performance groups manage their suppliers. Findings: Four clusters that are distinct sets of food firms with detailed references about their typical characteristics revealing their business performance and supplier management practices. Also, the study confirms that certificates, reliability and inspection results constitute the factor of quality-related criteria for food firms. It is an interesting insight into what firms prioritise in selecting and maintaining collaboration and relationships with suppliers that reflect actual demanding specifications for supplier conformity. Research limitations/implications: The study reveals the business status of the studied companies and each group's specific references, such as the criteria they prefer to select suppliers, the relationship quality and the level of collaboration. Originality/value: The study is a useful reference for both researchers and practitioners to have a comprehensive view of supplier management in the food industry based on the viewpoint of Asian food manufacturers.

Background: Data on recent human immunodeficiency virus (HIV), hepatitis C virus (HCV) and syphilis prevalence among drug users in the Southwest China are sparse despite the high burden of drug use. This study aims at assessing the prevalence trends and related factors of HIV, HCV and syphilis infection among different drug users in the China–Vietnam border area. Methods: A continuous cross-sectional survey was conducted among drug users from 2010 to 2020 in the China–Vietnam border area. Chi-square trend tests were used to assess the trend of HIV, HCV and syphilis prevalence and the proportion for drug type used by drug users. Multivariate logistic regression was used to identify associated factors of HIV, HCV and syphilis infection in different drug users. Results: In this study, a total of 28,951 drug users were included, of which 27,893 (96.45%) male, 15,660 (54.09%) aged 13–34 years, 24,543 (84.77%) heroin-only users, 2062 (7.12%) synthetic drug-only (SD-only) users and 2346 (8.10%) poly-drug users. From 2010 to 2020, the proportion of heroin-only users decreased from 87.79% to 75.46%, whereas SD-only users and poly-drug users increased from 5.16% to 16.03%, and from 7.05% to 8.52%, respectively. The prevalence of HIV, HCV, and syphilis during the study period declined from 12.76%, 60.37% and 5.72% to 4.35%, 53.29% and 4.53%, respectively, among heroin-only users and declined from 18.30%, 66.67% and 15.69% to 6.95%, 27.81% and 5.35%, respectively, among poly-drug users; however, the prevalence of HIV and HCV among SD-only users increased from 0.89% and 8.93% to 2.84% and 18.75%, respectively. Having ever injected drugs and needle sharing were common associated factors for both HIV and HCV infection among poly-drug users and heroin-only users. Aged ≥ 35 years old was an associated factor for HIV, HCV and syphilis infection among the SD-only users. Female drug users were at high risk of contracting syphilis among three different drug users. Conclusions: The prevalence of HIV, HCV and syphilis among heroin-only users and poly-drug users decreased during the study period. However, the prevalence of HIV and HCV among SD-only users increased. Comprehensive intervention strategies, particularly focusing on the SD-only users are needed in order to bring down the disease burden in this population in the China–Vietnam border areas.

- Abstract
COVID-19 school closures in East Asia and the Pacific threaten to widen existing learning inequities and increase the number of children out of school. During the pandemic, governments rapidly deployed remote learning strategies, ranging from paper-based take-home materials to digital platforms. However, lack of electricity -- critical to connectivity -- remains a key obstacle for the region, particularly in rural areas. Therefore, while digital learning platforms were offered by most Southeast Asian countries, take-up was low. A combination of modalities -- including mobile phone-based learning strategies -- and collaboration with a range of non-governmental education stakeholders have the potential to enhance the reach of remote learning and to make it more engaging for students. Lessons from the regional implementation of these strategies emphasize the importance of research to understand the needs of students, educators and parents and the impact of remote learning, especially in low-resource contexts.

SPECIES ,TAXONOMISTS ,BASIDIOMYCOTA - Abstract
The genus is a special and crucial taxonomic rank compared with others above the species level, because a species has to be placed in a certain genus instead of any other higher ranks. With more and more new species being described, the placements of their generic position are sometimes incorrect due to the simple phylogenies resulting from inappropriate sampling. Here, we focus on the taxonomy of a small wood-inhabiting fungal genus Hyphodermella. With the most comprehensive sampling to date, the phylogenetic position of Hyphodermella within Phanerochaetaceae is rearranged by employing the same ITS and nLSU regions as in previous studies and also the ITS, nLSU, rpb1, rpb2 and tef1α regions. Three species are excluded from Hyphodermella: H. poroides is placed in a newly introduced monotypic genus Pseudohyphodermella, while H. aurantiaca and H. zixishanensis are transferred to Roseograndinia. Hyphodermella suiae is described as a new species from South China and Vietnam. Keys to eight species in Hyphodermella and five in Roseograndinia are provided. Beyond solving the taxonomic issue of Hyphodermella itself, the current study also aims to suggest that all fungal taxonomists especially beginners should keep in mind to sample as many comprehensive taxa as possible in phylogenetic analyses.

Simple Summary: The assassin bugs (Heteroptera: Reduviidae) are one of the largest and morphologically most diverse families of true bug, having essential impacts on forest ecosystems as predators. The spinous reduviid genus Sclomina exhibits shape mimicry and protective coloration adapted to the spinous Rubus plant that they inhabit. The genus Sclomina shows gradual morphological variability, so its morphological classification is still unresolved, and its biology is almost unknown. In this study, DNA barcodes and morphological evidence were combined to accurately divide the species of a comprehensive collection sampled in South China and North Vietnam. We found three cryptic species. The biological information and mimicry behavior uncover their successive evolutionary survival strategies. Sclomina Stål, 1861 (Heteroptera: Reduviidae: Harpactorinae) is endemic to China and Vietnam, with only two species, Sclomina erinacea Stål, 1861 and Sclomina guangxiensis Ren, 2001, characterized by spinous body and dentate abdominal connexivum. However, due to variable morphological characteristics, Sclomina erinacea, which is widely distributed in South China, is possibly a complex of cryptic species, and Sclomina guangxiensis was suspected to be an extreme group of the S. erinacea cline. In the present study, we conducted species delimitation and phylogenetic analyses based on the mitochondrial cytochrome c oxidase subunit I (COI) gene sequences of 307 Sclomina specimens collected from 30 sampling localities combined with morphological evidence. The result showed that all samples used in this study were identified as five species: Sclomina guangxiensis is a valid species, and Sclomina erinacea actually includes three cryptic species: Sclomina xingrensis P. Zhao and Cai sp. nov., Sclomina pallens P. Zhao and Cai sp. nov., and Sclomina parva P. Zhao and Cai sp. nov. In this paper, the genus Sclomina is systematically revised, and the morphological characteristics of the five species are compared, described, and photographed in detail. We elucidate the evolutionary history of Sclomina based on results of estimated divergence time. The body shape and coloration (green in nymph and brown in adult) of Sclomina match their environment and mimic the Rubus plants on which they live. The symbiotic relationship between Sclomina and spinous Rubus plants is presented and discussed. [ABSTRACT FROM AUTHOR]

Background: Porcine circovirus type 2 (PCV2) has caused great economic losses in the global pig industry. There have been published records of wild rats acting as the reservoirs of PCV2 (only PCV2a and PCV2b), but almost all of which were related to the PCV2-infected swine herds. Results: In this study, we carried out the detection, amplification, and characterization of novel PCV2 strains in wild rats that were captured far from pig farms. Nested PCR assay demonstrated that the kidney, heart, lung, liver, pancreas, and large and small intestines of rats were screened positive for PCV2. We subsequently sequenced two full genomes of PCV2 in positive sample pools, designated as js2021-Rt001 and js2021-Rt002. Genome sequence analysis indicated that they had the highest similarity to nucleotide sequences of porcine-origin PCV2 isolates in Vietnam. Phylogenetically, js2021-Rt001 and js2021-Rt002 were a part of the PCV2d genotype cluster, which is a predominant genotype circulating worldwide in recent years. The antibody recognition regions, immunodominant decoy epitope, and heparin sulfate binding motif of the two complete genome sequences coincided with those previously reported. Conclusions: Our research reported the genomic characterization of two novel PCV2 strains (js2021-Rt001 and js2021-Rt002) and provided the first supported evidence that PCV2d could naturally infect wild rats in China. However, whether the newly identified strains have potential for circulating in nature in vertical and horizontal transmission or inter-species jumping between rats and pigs needs further research.

Climate change is an important driver of species distribution and biodiversity. Understanding the response of plants to climate change is helpful to understand species differentiation and formulate conservation strategies. The genus Polyspora (Theaceae) has an ancient origin and is widely distributed in subtropical evergreen broad‐leaved forests. Studies on the impacts of climate change on species geographical distribution of Chinese Polyspora can provide an important reference for exploring the responses of plant groups in subtropical evergreen broad‐leaved forests with geological events and climate change in China. Based on the environmental variables, distribution records, and chloroplast genomes, we modeled the potential distribution of Chinese Polyspora in the Last Glacial Maximum, middle Holocene, current, and future by using MaxEnt‐ArcGIS model and molecular phylogenetic method. The changes in the species distribution area, centroid shift, and ecological niche in each periods were analyzed to speculate the response modes of Chinese Polyspora to climate change in different periods. The most important environmental factor affecting the distribution of Polyspora was the precipitation of the driest month, ranging from 13 to 25 mm for the highly suitable habitats. At present, highly suitable distribution areas of Polyspora were mainly located in the south of 25°N, and had species‐specificity. The main glacial refugia of the Chinese Polyspora might be located in the Ailao, Gaoligong, and Dawei Mountains of Yunnan Province. Jinping County, Pingbian County, and the Maguan County at the border of China and Vietnam might be the species differentiation center of the Chinese Polyspora. Moderate climate warming in the future would be beneficial to the survival of P. axillaris, P. chrysandra, and P. speciosa. However, climate warming under different shared socio‐economic pathways would reduce the suitable habitats of P. hainanensis and P. longicarpa. [ABSTRACT FROM AUTHOR]

Manglietia conifera Dandy is a fast-growing tree species that has been introduced to China from Vietnam, which has great potential for commercial planting. However, plantation development is hindered by a lack of seed material, due to low natural seed-set in locally grown trees. Thus, we investigated the morphological characteristics of male and female flower organs, and conducted controlled pollination to understand the breeding systems of the species. The individual flower of M. conifera is bisexual, and the stamen group is polymerized at the base of the receptacle. Pollen is symmetrically distributed on both sides. Controlled pollination suggests that apomixis does not occur in M. conifera. Results from the flower structure, pollen–ovule ratio, outcrossing index, and controlled pollination indicated that the breeding system in M. conifera was outcrossing (partially self-compatible, pollinators required), and self-incompatibility occurred in a later stage of embryonic development. Moreover, the self-incompatibility phenomenon was revealed by the abnormal germination of pollen on the stigma. This paper provides a basis for controlled pollination programs of M. conifera.

Globally, populations are ageing and the estimated number of hip fractures will increase from 1.7 million in 1990 to more than 6 million in 2050. The greatest increase in hip fractures is predicted in Low- and Middle-Income Countries (LMICs), largely in the Asia-Pacific region where direct costs are expected to exceed $US15 billion by 2050. The aims of this qualitative study are to identify barriers to, and enablers of, evidence-informed hip fracture care in LMICs, and to determine if the Blue Book standards, developed by the British Orthopaedic Association and British Geriatrics Society to facilitate evidence-informed care of patients with fragility fractures, are applicable to these settings. This study utilized semi-structured interviews with clinical and administrative hospital staff to explore current hip fracture care in LMICs. Transcribed interviews were imported into NVivo 12 and analysed thematically. Interviews were conducted with 35 participants from 11 hospitals in 5 countries. We identified five themes-costs of care and the capacity of patients to pay, timely hospital presentation, competing demands on limited resources, delegation and defined responsibility and utilization of available data-and within each theme, barriers and enablers were distinguished. We found a mismatch between patient needs and provision of recommended hip fracture care, which in LMICs must commence at the time of injury. This study describes clinician and administrator perspectives of the barriers to, and enablers of, high-quality hip fracture care in LMICs; results indicate that initiatives to overcome barriers (in particular, delays to definitive treatment) are required. While the Blue Book offers a starting point for clinicians and administrators looking to provide high-quality hip fracture care to older people in LMICs, locally developed interventions are likely to provide the most successful solutions to improving hip fracture care.

Simple Summary: This study examines colour variation in the highly endangered crocodile lizard, Shinisaurus crocodilurus. Both males and females vary in the extent to which their throats and venters are red. Their colouration is easily visible to a lizard receiver, and we found evidence that colour signals individual quality. Females with red venters had larger heads while females with red throats had greater bite force. In males, redder individuals were older. Finally, we found links between colour and fitness in males but not females. Aspects of male colouration were linked to reproductive output such that they sired offspring from heavier litters. The potential fitness consequences of colour should be considered in captive breeding and release programs. Colour plays a key role in animal social communication including as an indicator of individual quality. Using spectrophotometry, we examined colour variation in the throat and venter of the crocodile lizard (Shinisaurus crocodilurus), an endangered species native to southern China and northern Vietnam. We detected two broad colour variants, individuals with and without red, for each body region and each sex. A cluster analysis of spectral colour measurements (hue, chroma, luminance) revealed discrete throat and ventral morphs when measured in a single snapshot in time. However, photographic evidence revealed that the amount of red relative to body size increased as they got older. Individuals with red were equally likely to be male or female and throat colour was unrelated to ventral colour. Therefore, it is premature to claim that crocodile lizards have discrete colour morphs. We used visual modelling to show that the throat and venter were easily discriminable to a lizard visual system, suggesting they function in social communication. We also asked whether colour variation signalled individual quality. Females with red throats had greater bite force while males with red throats were older. In addition, females with red venters had larger heads. We also detected differences in morphology linked to colour. Females with red throats had slender bodies and longer tails, while individuals lacking red on their throats were stouter and had shorter tails. Finally, throat and ventral colour were unrelated to reproductive output (litter size and mass) in females. Males with greater ventral luminance contrast sired offspring from litters with greater litter mass (including stillborns), while males with greater ventral chromatic contrast sired offspring whose collective live mass (excluding stillborns) was greater. Males with greater luminance contrast also sired more live offspring (excluding stillborns). Collectively, these results suggest that male ventral colour signals individual quality in males. Conservation initiatives should take colour variation into account when planning future captive breeding and release programs for this endangered species. [ABSTRACT FROM AUTHOR]

This article attempts to explain why China-Vietnam relations, which were based on tributary ties, broke down when France conquered Vietnam in the 19th century. As such, it traces the history of China- Vietnam-France relations, particularly on the eve of the French invasion of Vietnam, and explores China’s efforts to defend the country. This study is significant because it sheds light on the history of the French conquest of Vietnam while it was under the Chinese tributary system. For almost a century, China claimed to have power as a presidential state over Vietnam. However, the French did not acknowledge China’s power. Moreover, one by one, the territories of Vietnam were seized and eventually conquered by France. In this study, qualitative content analysis was applied to primary and secondary sources to evaluate the extent to which the tributary system affected and influenced the international external relations between the three countries of the three countries. The study’s findings showed that Vietnam had autonomy in theory but was submissive and willingly under China’s protection regarding its foreign affairs. However, the French did not recognize the tributary system as a foreign relationship, and they continued to mobilise colonial efforts in Vietnam in the mid-late 19th century. [ABSTRACT FROM AUTHOR]

There is limited information on the feeding practices of 9.42 million children living within institution‐based care (IBC) worldwide. Poor feeding practices can predispose or exacerbate malnutrition, illness and disability. Here we describe the feeding practices of children living within IBC based on a retrospective analysis of records from 3335 children, 0–18 years old, participating in Holt International's Child Nutrition Program (CNP), from 36 sites in six countries. Data analysed included demographic information on age, sex, feeding practices, disabilities and feeding difficulties. Descriptive statistics were produced. A generalised linear model explored associations between feeding difficulties and disability and 2 × 2 tables examined feeding difficulties over time. An additional set of feeding observations with qualitative and quantitative data was analysed. At baseline, the median age of children was 16 months (0.66–68 months) with 1650/3335 (49.5%) females. There were 757/3335 (22.7%) children with disabilities; 550/984 (55.9%) were low birth weight; 311/784 (39.7%) were premature; 447/3113 (14.4%) had low body mass index and 378/3335 (11.3%) had feeding difficulties. The adjusted risk of having a feeding difficulty was 5.08 ([95% confidence interval: 2.65–9.7], p ≤ 0.001) times greater in children with disabilities than those without. Many children saw their feeding difficulties resolve after 1‐year in CNP, 54/163 (33.1%) for children with disabilities and 57/106 (53.8%) for those without disabilities. Suboptimal hygiene, dietary and feeding practices were reported. In conclusion, feeding difficulties were common in IBC, especially among children with disabilities. Supporting safe interactive mealtimes for children living within IBC should be prioritised, to ensure overall health and development. Key points: Feeding difficulties are common among children living in institution‐based care (IBC), particularly but not exclusively among those children with disabilities.Suboptimal feeding practices were common in IBC and encompassed inadequate hygiene, limited support for self‐feeding, reading children's feeding cues (especially around pacing and satiety), addressing feeding difficulties, such as difficulty chewing or swallowing. These should be prioritised in training and supervision for caregivers.Addressing the needs of this vulnerable group should include support for safe feeding techniques. These should be prioritised to help ease the transition into eventual family‐based care if we are to move towards deinstitutionalizing children and strengthening families. [ABSTRACT FROM AUTHOR]

Cynomolgus macaques, the most commonly utilized nonhuman primate in nonclinical toxicology studies, are acquired from purpose-bred colonies across various geographic locations, including China, Cambodia, and Vietnam. Importation challenges and limited availability have restricted animals suitable for inclusion in nonclinical studies. The coronavirus disease 2019 (COVID-19) outbreak further stressed supply chains, reducing the ability to source animals from a singular location to complete a drug development program. These challenges raised concerns of increased variability in study endpoints due to heterogeneity of animals and that this could subsequently impact historical control data and toxicology study interpretation. To investigate the impact of Chinese, Vietnamese, or Cambodian geographic origin on standard nonclinical toxicology study endpoints, historical control data from studies conducted at a single facility from 2005 to 2020 were compiled and evaluated for the following: clinical observations, body weight, ophthalmoscopic examinations, and clinical and anatomic pathology data. Study populations consisted of 2- to 5-year-old cynomolgus macaques sourced from China (n = 750 males/741 females), Cambodia (n = 282 males/271 females), and Vietnam (n = 122 males/120 females). Interpretation of the various data demonstrated no notable differences in standard toxicology study endpoints or background findings among cynomolgus macaques originating from China, Cambodia, or Vietnam.
