Hydroclimate variability of western Thailand during the last 1400 years
2020
Mainland Southeast Asia is located on the moisture transport route of the Indian summer monsoon (ISM) where hydroclimate records from speleothems have rarely been investigated. Here, we present a new multi-proxy (δ18O and δ13C values, trace element concentrations, and grayscale values) data set of stalagmite KPC1 from Khao Prae cave in western Thailand spanning the last 1400 years (500–1900 CE; the Common Era). These multi-proxy data reveal a high variability between the wet and dry periods during 500–850 CE and 1150–1300 CE, stable climate conditions during 850–1150 CE, and overall dry conditions since 1300 CE. The δ13C values, trace elements concentrations, and grayscale values show cente…
A mysterious dwarf: Suthepiidae nov. fam., a new harvestman family from mountains of northern Thailand (Arachnida: Opiliones: Laniatores)
2020
A new family of laniatorean harvestmen from northern Thailand is proposed, Suthepiidae fam. nov., which comprises one new genus and one new species, Suthepia inermis sp. nov. This family stands out by characters hitherto unknown or rarely recorded for Opiliones, and close relatives of this taxon are presently not discernible. Important characters are a short and compact penis with a massively enlarged distal part with a rich armament of sclerites and membranes which can be moved and everted by hemolymph pressure during mating; the pedipalp of males and females is without raptorial adaptations, i.e. elevated sockets (= apophyses) carrying strong distal spines are completely absent, therefore…
Late Cretaceous-Early Eocene origin of yams (Dioscorea, Dioscoreaceae) in the Laurasian Palaearctic and their subsequent Oligocene-Miocene diversific…
2015
Aim: Dioscorea (Dioscoreaceae) is a predominantly pantropical genus (< 600 species) that includes the third most important tropical tuber crop and species of pharmacological value. Fossil records from both the Northern and Southern Hemispheres were used to test hypotheses about the origin of the genus Dioscorea, and to examine potential macroevolutionary processes that led to its current distribution. Location: Pantropical distribution. Methods: Divergence times were estimated using the most comprehensive phylogeny of the group published to date based on plastid sequences and fossil calibrations, applying a relaxed-clock model approach. Ancestral areas and range shifts were reconstructed us…
2019 revised algorithm for the management of knee osteoarthritis: the Southeast Asian viewpoint
2021
Abstract Background Since 2014, the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) algorithm for the management of knee osteoarthritis (OA) is available worldwide. Aim Based on this document, a Southeast Asia Working Group (SEAWG) wished to see how the new ESCEO algorithm developed in 2019 was perceived by Southeast Asian experts and how it was integrated into their clinical practice. Methods A SEAWG was set up between members of the international ESCEO task force and a group of Southeast Asian experts. Results Non-pharmacological management should always be combined with pharmacological management. In step 1, symptoma…
Molecular phylogenetics of Melastomataceae and Memecylaceae: implications for character evolution
2001
Melastomataceae are among the most abundant and diversified groups of plants throughout the tropics, but their intrafamily relationships and morphological evolution are poorly understood. Here we report the results of parsimony and maximum likelihood (ML) analyses of cpDNA sequences from the rbcL and ndhF genes and the rpl16 intron, generated for eight outgroups (Crypteroniaceae, Alzateaceae, Rhynchocalycaceae, Oliniaceae, Penaeaceae, Myrtaceae, and Onagraceae) and 54 species of melastomes. The sample represents 42 of the family’s currently recognized ~150 genera, the 13 traditional tribes, and the three subfamilies, Astronioideae, Melastomatoideae, and Memecyloideae (= Memecylaceae DC.). P…
Critical factors influencing international sporting success of the Philippines : the athletes' perspective
2017
The aim of this study is to contribute to the understanding of the recent declining performance of the Philippines in international sporting competitions by identifying and evaluating relevant factors that are critical to its international success through the perspective of the national elite athletes. An evaluation of the organizational effectiveness of the national sports governing bodies provides explanation to the poor performance of the country in major international competitions such as the Southeast Asian (SEA)Games. One of the most recent approaches used in measuring organizational effectiveness is the Sport Policy factors Leading to International Sporting Success (SPLISS) model. Th…
Inflectional speaker-role classifiers in Weining Ahmao
2008
Abstract This paper is the first of two (see references) aiming to bring to the attention of pragmaticians an idiosyncratic classifier system that encodes speaker-roles along the lines of gender and age. Isolating (analytic) languages are known for their scarcity of word forms and for their under-specification of grammatical categories. Analytic languages in East and Southeast Asian involve classifiers – a word category without counterpart in most languages of the inflectional type – to attenuate some of the vagueness in the nominal realm. Similar to other parts of speech, the classifier generally constitutes a one-form word category with occasional sandhi-derivations. Weining Ahmao, a Miao…
DIURNAL RAINFALL VARIATION IN MALAYA1
1968
ABSTRACT In low latitudes, where seasonal differences of climate are small and usually limited to factors such as winds and precipitation, the weather is largely controlled by diurnal processes. The diurnal variation of rainfall is the most important result of these processes and it is a characteristic part of the climate. In Malaya, diurnal rainfall regimes show seasonal variations, which are closely related to the system of the southeast Asian monsoons. The seasonal variations differ according to location, and three regional types can be recognized, which are found, respectively, at the west coast, the east coast, and at inland stations. Singapore, because of its extreme location at the s…
Horizontal and elevational phylogeographic patterns of Himalayan and Southeast Asian forest passerines (Aves: Passeriformes)
2011
Aim Zoogeographic patterns in the Himalayas and their neighbouring Southeast Asian mountain ranges include elevational parapatry and ecological segregation, particularly among passerine bird species. We estimate timings of lineage splits among close relatives from the north Palaearctic, the Sino-Himalayan mountain forests and from adjacent Southeast Asia. We also compare phylogeographic affinities and timing of radiation among members of avian communities from different elevational belts. Location East Asia. Methods We reconstructed molecular phylogenies based on a mitochondrial marker (cytochrome b) and multilocus data sets for seven passerine groups: Aegithalidae, Certhiidae (Certhia),…
The Effects of Taxation on Migration: Some Evidence for the ASEAN and APEC Economies
2010
This paper investigates the effects of taxation on migration. It develops a stylized, two-country model to examine the impact of taxes on labor mobility. The theoretical predictions that taxes affect migration decisions and that educated workers are more responsive to taxation are supported by some empirical evidence for the economies of the Association of Southeast Asian Nations and the Asia-Pacific Economic Cooperation. The empirical application also shows that average tax rates have a larger impact on migration choices than marginal rates. Average tax rates are most important for migrants with secondary education, while marginal rates have a greater influence on the decisions of migrants…
