AbstractThe recent discovery of continuous tree-ring series starting as early as 1030 CE has for the first time made possible the reconstruction of historical climates for much of mainland Southeast Asia. Perhaps the most dramatic finding is that wide cyclic fluctuations in the reach and volume of monsoon rains contributed substantially to both the genesis and the collapse of the charter civilizations of Angkor, Pagan, and Dai Viet. Fromcirca1450–1820 climate continued to influence political and economic development, but its impact appears to have diminished both because the amplitude of hydrological fluctuations decreased markedly, and because new sources of power rendered early modern Southeast Asian states more resilient. A pioneering collaborative effort by a historian and a paleoclimatologist, this paper promises three benefits: It can help to solve a variety of local historiographic puzzles, it can facilitate construction of a synchronized historical narrative for mainland Southeast Asia as a whole, and it can aid comparisons between mainland Southeast Asia and other sectors of Eurasia.

The micropolydesmoid millipede family Haplodesmidae is here recorded from Cambodia for the first time through the discovery of the first, new species of the genus Eutrichodesmus Silvestri, 1910: E. cambodiensissp. nov. This new species is described from two limestone habitats in Kampot Province, based on abundant material. It is easily distinguished from all related congeners by the following combination of characters: body greyish-brown; limbus roundly lobulate; solenomere partially divided from acropodite by a digitiform lobe, but without hairpad. Brief remarks on the previously-proposed “pecularis-group” are provided and a second group, the “demangei-group”, is established and discussed on the basis of morphological evidence, updating the number of recognised species groups of Eutrichodesmus to two. Detailed morphological illustrations, photographs and a distribution map, as well as remarks on its habitat and mating behaviour of the new species are presented. Furthermore, the current distributions of all 55 presently-known species of Eutrichodesmus are provided and a key to all 23 species that occur in mainland Southeast Asia is given.

Purpose This paper aims to explore the relationship between environmental regulation, technological innovation and manufacturing quality competitiveness to provide some references for emission reduction activities and improvements in manufacturing quality competitiveness to achieve environmental protection targets and economic development as part of a win–win situation. Design/methodology/approach Based on the structure-behavior-performance paradigm and Grabowski’s research, a new empirical model was provided. The software, EViews 6.0, was used for econometric analysis. Regression analysis was adopted to explore the three indicators’ relationships. Findings First, environmental regulation can promote technological innovation effectively. Second, compared with wasted gas and wasted solids, investment in wasted water control promotes Chinese technological innovation most. Third, the impact of research and development investment, induced by environmental regulation, on manufacturing quality competitiveness is greater than that induced by non-environmental regulation. Fourth, the impact of lagged two-phase environmental regulation on manufacturing quality competitiveness is similar to that of lagged one-phase regulation. Practical implications The issue that Chinese manufacturing is facing is how to manage the trade-off between pollution control investment and improved quality competitiveness. This study enables managers to understand how to better implement environmental regulation initiatives while achieving environmental protection and quality competitiveness as part of a win–win situation. Originality/value This paper analyzes the relationships between environmental regulation, technological innovation and manufacturing quality competitiveness for the first time and provides the basic argument for integrating Chinese environmental regulation with quality competitiveness to reveal the uniqueness of the circumstances determining China’s economic development.

In spite of high incidence of α-thalassemia as the most common inherited disorder of hemoglobin (Hb) production in Southeast Asia, the role of point mutations in this aspect not still well known. This fact can lead to missing rare variants of α-thalassemia mutations by the routine screening, which they may need to be screened for possibility of causing Hb H disease. In this study we found two insertions in alpha1 gene which cause to Hb H disease. One of the insertions, 108/109, is a new findings and another one, codon 44, is the mutation which has been followed for the first time. These new molecular findings about changes in α-globin production which results in decreased of hemoglobin (Hb) value, have high-impact clinical importance.

Hymenopteran Insects

Besides the unsustainable exploitation, farming activities and economic development activities, forest fire is considered as one of the major threats to biodiversity and deforestation in Vietnam. In forest ecosystems, any changes in insect communities can affect species composition, nutrient cycling and numerous other ecological processes. The impact of forest fires, however, is not equal to different insect groups. In this paper, we study the impact of forest fires to hymenopteran insects at Copia species-use forest, Son La Province. This is the first time this kind of study has been taken place in Vietnam. Bên cạnh việc khai thác không bền vững, tập quán canh tác và các hoạt động phát triển kinh tế, cháy rừng được xem là một trong những mối đe dọa chính ảnh hưởng tiêu cực tới đa dạng sinh học và mất rừng ở Việt Nam. Trong các hệ sinh thái rừng, những thay đổi trong cấu trúc của quần xã côn trùng có ảnh hưởng tới thành phần loài, chu trình dinh dưỡng và rất nhiều quá trình sinh thái khác. Tuy nhiên mức độ ảnh hưởng của cháy rừng tới các nhóm côn trùng khác nhau là khác nhau. Trong bài báo này, chúng tôi nghiên cứu tác động của cháy rừng tới nhóm côn trùng cánh màng tại khu rừng đặc dụng Copia, tỉnh Sơn La. Đây cũng là lần đầu tiên tác động của cháy rừng tới nhóm côn trùng cánh màng được thực hiện ở Việt Nam.

The release of global gridded population datasets, including the Gridded Population of the World (GPW), Global Human Settlement Population Grid (GHS-POP), WorldPop, and LandScan, have greatly facilitated cross-comparison for ongoing research related to anthropogenic impacts. However, little attention is paid to the consistency and discrepancy of these gridded products in the regions with rapid changes in local population, e.g., Mainland Southeast Asia (MSEA), where the countries have experienced fast population growth since the 1950s. This awkward situation is unsurprisingly aggravated because of national scarce demographics and incomplete census counts, which further limits their appropriate usage. Thus, comparative analyses of them become the priority of their better application. Here, the consistency and discrepancy of the four common global gridded population datasets were cross-compared by combing the 2015 provincial population statistics (census and yearbooks) via error-comparison based statistical methods. The results showed that: (1) the LandScan performs the best both in spatial accuracy and estimated errors, then followed by the WorldPop, GHS-POP, and GPW in MSEA. (2) Provincial differences in estimated errors indicated that the LandScan better reveals the spatial pattern of population density in Thailand and Vietnam, while the WorldPop performs slightly better in Myanmar and Laos, and both fit well in Cambodia. (3) Substantial errors among the four gridded datasets normally occur in the provincial units with larger population density (over 610 persons/km2) and a rapid population growth rate (greater than 1.54%), respectively. The new findings in MSEA indicated that future usage of these datasets should pay attention to the estimated population in the areas characterized by high population density and rapid population growth.

This article substantiates for the first time that Tay (Shan) script was written on a Ming dynasty scroll dated 1407. In the past, Tay scholars have assumed that early Tay script exhibited uniquely Tay characteristics from the outset, and only gradually acquired Burmese features after the eighteenth and nineteenth centuries. The data presented here demonstrates beyond doubt that the Tay borrowed heavily from the Burmese script to create their writing system before the fifteenth century. It also shows that the 1407 Tay script resembled the Ahom script more than the lik6 tho3 ngök6 script, and on the basis of this similarity concludes that lik6 tho3 ngök6 was not the progenitor of Tay scripts, as previously thought, and that the Ahom script preceded it.The impact of Burmese script on the Tay writing system from the outset raises the broader issue of borrowing from Burman culture during the Pagan and early Ava periods. The Tay of Mäng2 Maaw2 and surrounding polities turned to Pagan and Ava for a written script, but shunned Theravada Buddhism, the religious apparatus that we assume always accompanied the spread of writing. Their adoption of a writing system stands out as a rare case of script without Buddhism in northern continental Southeast Asia. To the Tay, Pagan and Ava were dominant political powers worthy of emulation, and the adoption of their writing system attests the magnitude of its influence. It is hypothesized that such borrowing arose out of Tay aspirations for self-strengthening their polities, possibly in an endeavour to rival the Burman monarchy. Tay script emerged in an age when the Burman language had just become predominant among the elites of Pagan and early Ava. Two features of this case stand out. First, the Tay borrowed at a time when Burmese script was relatively novel and still the preserve of the Burman elite, a fact which reinforces the notion of borrowing for prestige value as well as practical utility. Second, the Tay gravitated towards the northern parts of Pagan and Ava, rather than the southern areas where Mon language retained predominance in inscriptions.

Abstract Background As the largest group of mammalian species, which are also widely distributed all over the world, rodents are the natural reservoirs for many diverse zoonotic viruses. A comprehensive understanding of the core virome of diverse rodents should therefore assist in efforts to reduce the risk of future emergence or re-emergence of rodent-borne zoonotic pathogens. Results This study aimed to describe the viral range that could be detected in the lungs of rodents from Mainland Southeast Asia. Lung samples were collected from 3284 rodents and insectivores of the orders Rodentia, Scandentia, and Eulipotyphla in eighteen provinces of Thailand, Lao PDR, and Cambodia throughout 2006–2018. Meta-transcriptomic analysis was used to outline the unique spectral characteristics of the mammalian viruses within these lungs and the ecological and genetic imprints of the novel viruses. Many mammalian- or arthropod-related viruses from distinct evolutionary lineages were reported for the first time in these species, and viruses related to known pathogens were characterized for their genomic and evolutionary characteristics, host species, and locations. Conclusions These results expand our understanding of the core viromes of rodents and insectivores from Mainland Southeast Asia and suggest that a high diversity of viruses remains to be found in rodent species of this area. These findings, combined with our previous virome data from China, increase our knowledge of the viral community in wildlife and arthropod vectors in emerging disease hotspots of East and Southeast Asia.
