Consensus of Official Position of IOF/ISCD FRAX Initiatives in Asia-Pacific Region.

The fracture risk assessment tool (FRAX(®)) has been developed for the identification of individuals with high risk of fracture in whom treatment to prevent fractures would be appropriate. FRAX models are not yet available for all countries or ethnicities, but surrogate models can be used within regions with similar fracture risk. The International Society for Clinical Densitometry (ISCD) and International Osteoporosis Foundation (IOF) are nonprofit multidisciplinary international professional organizations. Their visions are to advance the awareness, education, prevention, and treatment of osteoporosis. In November 2010, the IOF/ISCD FRAX initiative was held in Bucharest, bringing together international experts to review and create evidence-based official positions guiding clinicians for the practical use of FRAX. A consensus meeting of the Asia-Pacific (AP) Panel of the ISCD recently reviewed the most current Official Positions of the Joint Official Positions of ISCD and IOF on FRAX in view of the different population characteristics and health standards in the AP regions. The reviewed position statements included not only the key spectrum of positions but also unique concerns in AP regions.

Late mesozoic to neogene radiolarian biostratigraphy and palaeoceanography in the Caribbean and East pacific region

^Raduolarians constitute a good tool for contributing to the biostratigraphy of accreted terranes and in deep-sea sediment sequences. The use of radiolarians is also proven to be valuable as a palaeoceanographic indicator. The present study evaluates radiolarians in three different geological settings, in order to better constrain the age of the sites and to try to understand their palaeoenvironmental situation at different periods, particularly in the Caribbean-Central America area. On the Jarabacoa Block, in Central Dominican Republic, a hundred meters of siliceous mudstones (Pedro Brand section in the Tireo Group) was dated as Turonian- Coniancian in age using radiolarians. A 40Ar-39Ar whole rock age of 75.1±1.1 Ma (Campanian), obtained in a basalt dyke crosscutting the radiolarian bearing rocks, a consistent minimum age for the pelagic-hemipelagic Pedro Brand section. The Jarabacoa Block is considered as the most complete outcrop section of Pacific ocean crust overlain by a first Aptian-Albian phase of Caribbean Large Igneous Province-type activity (CLIP), followed by the development of a Cenomanian-Santonian intraoceanic arc, which is in turn overlain by a late Campanian-Maastrichtian CLIP-phase. The Tireo Group records an episode of pelagic to hemi-pelagic and intermediate to acidic arc-derived sedimentation, previous to the youngest magmatic phase of the CLIP. Thus, the section of Pedro Brand has been interpreted in this study as being part of the intraoceanic arc. In northern Venezuela, a greenish radiolarite section from Siquisique Ophiolite (basalts, gabbros and some associated cherts) in Guaparo Creek has been studied. In previous studies, the Ophiolite unit (Petacas Creek section) has been dated as Bajocian-Bathonian, based on ammonites present in interpillow sediments from basalt blocks. New dating of the present study concluded in an Aptian?-Albian-Cenomanian age for the Guaparo creek section (middle Cretaceous), based on radiolarian assemblage associated to basalts-gabbros rocks of the unit. Previous plagioclase 40Ar-39Ar ages from the Siquisuique Ophiolite may be slightly younger (94-90 Ma.) and may, therefore, represent younger dykes that intruded onto a well-developed sheeted dyke complex of the Siquisique. The geochemistry of these rocks and the palaeotectonic reconstruction of the Caribbean area during this period suggest that these rocks were derived from a mid-ocean ridge with an influence of deep mantle plume. The Siquisique Ophiolite most probably represents a fragment of the proto-Caribbean basin. The Integrated Ocean Drilling Program Expedition 344 drilled a transect across the convergent margin off Costa Rica. Two sites of this expedition were chosen for radiolarian biostratigraphy and palaeoceanographic studies. Both sites (U1381C and U1414A) are located in the incoming Cocos plate, in the eastern Equatorial Pacific. The succession of U1381C yields a Middle Miocene to Pleistocene age, and presents an important hiatus of approximately 10 Ma. The core of U1414A exposes a continuous sequence that deposited during Late Miocene to Pleistocene (radiolarian zones RN6-RN16). The ages were assigned based on radiolarians and correlated with nannofossil zonation and tephra 40Ar-39Ar datation. With those results, and considering the northward movement of the Cocos plate motion (about 7 cm/year), deduction is made that the sites U1381C and U1414A were initially deposited during the Miocene, several hundreds of kilometres from the current location, slightly south of the Equator. This suggests that the faunas of these sites have been subjected to different currents, first influenced by the cold tongue of the South Equatorial Current and followed by the warm Equatorial Countercurrent. At last, coastal upwelling influenced faunas of the Pleistocene. -- Les radiolaires sont considérés comme un outil utile à la biostratigraphie des terrains accrétés et des sédiments profonds. Leur utilité est aussi prouvée comme étant remarquable au niveau des reconstructions paléocéanographiques. La présente étude évalue l'importance et la présence des radiolaires de trois localités géologiquement différentes d'Amérique Centrale-Caraïbes, dans le but d'améliorer les model d'âges et de mieux comprendre la situation paléoenvironnementale à travers le temps. Dans le Bloque de Jarabacoa, au centre de la République Dominicaine, une section de cent mètres (section de Pedro Brand, Groupe de Tireo) a été datée comme faisant partie du Turonien-Santonien, en utilisant les radiolaires. Une datation 40Ar-39Ar sur roche totale de 75±1.1 Ma (Campanien) a été obtenu pour vin dyke traversant les sédiments riches en radiolaires, en cohérence avec l'âge minimum accordé à la section de Pedro Brand. Aux Caraïbes, le Bloque de Jarabacoa est considéré comme l'affleurement le plus complet présentant une succession de croûte océanique d'origine Pacifique recouverte d'une première phase d'activité volcanique de type CLIP (Caribbean Large Igneous Province) d'âge Aptien- Albien, de dépôts d'arc volcanique intra-océanique d'âge Cénomanien-Santonien, puis d'une seconde phase de type CLIP d'âge Campanien-Maastrichtien. Le Groupe de Tireo enregistre un épisode de dépôt pélagiques-hémipélagiques et d'arc volcanique, antérieur à la plus jeune phase de type CLIP. Cette étude place donc la formation de la section de Pedro Brand au moment du développement de l'arc intra-océanique. A Guaparo Creek (nord du Vénézuela), une section de radiolarite verdâtre faisant partie des ophiolites de Siquisique (basaltes, gabbros, cherts) a été étudiée. Dans des études précédentes, sur la localité de Petacas Creek, l'unité ophiolitique a été daté d'âge Bajocien- Bathonien (Jurassique) sur la base d'ammonites trouvées dans des sédiments intercalés entre des laves en coussins. Les nouvelles datations de notre étude, basées sur des assemblages à radiolaires de l'unité à basaltes-gabbros, donnent un âge Aptien?-Albien-Cénomanien (Crétacé moyen). Les âges de l'Ophiolite de Siquisique, précédement calculés par la méthode sur plagioclases, pourraient être légèrement plus jeune (94-90 Ma) et donc représenter des intrusions plus récentes de dykes dans le complexe filonien déjà bien dévelopé. La géochimie de ces roches magmatiques, ainsi que les reconstructions paléotectoniques de la zone Caraïbes durant cette période, suggèrent que ces formations sont dérivées d'une ride médio-océanique associée à l'influence d'un panache mantellique. L'ophiolite de Siquisique représente très probablement un fragment du bassin de proto¬Caraïbe. L'expédition 344 du programme IODP (Integrated Ocean Drilling Program) a eu lieu dans l'optique de forer et dresser une coupe de la marge convergente au large du Costa Rica. Deux sites de cette expédition ont été choisis pour les besoins des études de biostratigraphie et de reconstruction paléocéanographique. Ces deux sites (U1381C et U1414A) sont situés sur la plaque subductante de Cocos, dans la zone Pacifique est-équatoriale. La carotte U1381C expose une séquence s'étalant du Miocène moyen au Pléistocène, et présente un important hiatus d'environ 10 Ma. La carotte U1414A expose une séquence continue s'étalant du Miocène tardif au Pléistocène (zone à radiolaires RN6-RN16). Les âges ont été assignés sur la base des radiolaires et corrélés avec les zones à nanofossiles et les datations 40Ar-39Ar sur téphras. Avec ces résultats, et en considérant le mouvement nord de la plaque de Cocos (environ 7 cm/an), déduction est faite que les deux sites étaient initialement situés, au cours du Miocène, à plusieurs centaines de kilomètres de leur location actuelle, au sud de l'équateur. Cela suggère que les faunes de ces sites ont été sujettes à différents courants; premièrement influencées par la langue froide du SEC (South Equatorial Current), puis par les eaux chaudes du ECC (Equatorial Countercurrent). Pour terminer, les remontées d'eau côtières ont influencées les faunes Pléistocène.

Les symbioses industrielles : une nouvelle stratégie pour l'amélioration de l'utilisation des ressources matérielles et énergétiques par les activités économiques

RésuméCette thèse traite d'un domaine d'application de l'écologie industrielle, les symbioses industrielles, comme stratégie d'amélioration de la consommation des ressources matérielles et énergétiques et de la gestion des déchets par les activités économiques. Les symbioses industrielles cherchent à créer de nouvelles collaborations directement entre les acteurs économiques d'un territoire dans le but d'échanger de l'information, des matières premières et des déchets, et d'intensifier les mutualisations de services et d'infrastructures possibles entre entreprises voisines. Ces quatre types de collaboration sont représentés schématiquement dans la figure ci-dessous.Dans ce travail, la détection et la mise en oeuvre de symbioses industrielles sont abordées sous plusieurs angles. Les recherches réalisées concernent le développement de procédures de mise en oeuvre s'adressant aux collectivités publiques, aux institutions académiques et aux bureaux de conseil dans le domaine de l'environnement. Les objectifs des procédures sont de créer une dynamique de collaboration et de confiance entre les acteurs économiques et l'administration publique d'un territoire afin de détecter des symbioses industrielles potentielles. Ces procédures requièrent la gestion de grandes quantités d'informations relatives aux flux de matière et d'énergie.Un travail de terrain, réalisé sur les territoires du canton de Genève et de Lausanne Région et utilisé comme études de cas, a permis de mettre en évidence un grand nombre de symbioses industrielles qui existent déjà en Suisse romande. Plusieurs dizaines d'exemples ont été identifiés principalement dans lesdomaines de la gestion de l'eau, de l'énergie, des produits chimiques et des matériaux de construction. La législation suisse autoriserait cependant la concrétisation de nombreuses autres opportunités. Dans cette recherche, celles-ci sont évaluées techniquement, légalement, économiquement et environnementalement. La création d'un référentiel d'évaluation des opportunités permet de déterminer quelles sont les symbioses industrielles techniquement réalisables et pertinentes dans le contexte suisse et dans quels cas celles-ci représenteraient une réelle plus-value par rapport à l'utilisation actuelle de la ressource et aux filières existantes de collecte et de valorisation des déchets.Finalement, un logiciel, SymbioGIS, destiné à soutenir la détection et l'évaluation de symbioses industrielles potentielles a été développé. Il s'agit d'une interface web accessible pour de nombreux utilisateurs, couplée à une interface de systèmes d'information géographique. En plus de la détection de symbioses industrielles, plusieurs fonctionnalités sont proposées pour faciliter la prise en compte des flux de matière et d'énergie dans les problématiques liées à l'aménagement du territoire et au positionnement des activités économiques.En conclusion, cette recherche met en évidence la nécessité de rapprocher les institutions publiques en charge de la protection de l'environnement, de la promotion économique et de l'aménagement du territoire pour favoriser l'essor des symbioses industrielles comme stratégie pour la gestion des ressources matérielles et énergétiques. Elle propose des pistes pour intensifier les collaborations entre ces domaines et accélérer le partage des connaissances liées aux flux de matière et d'énergie et à leur cheminement au sein des activités économiques afin de rendre le système industriel existant en Suisse romande viable à long terme. Parallèlement, elle étudie les possibilités de transposer ces considérations et les procédures et outils développés dans le contexte économique et social de la région Asie-Pacifique, où se trouvent aujourd'hui de nombreuses activités de production.SummaryIndustrial symbioses: A new strategy for improving how economic activities use material and energy resourcesThis thesis focuses on one application of industrial ecology, industrial symbioses, as a strategy for improving how economic activities consume material and energy resources. Industrial symbioses seek to create new collaborations among economic players with the goal of exchanging information, raw materials, and waste directly among area businesses, and to step up the potential pooling of services and infrastructure among neighboring companies.The identification and implementation of industrial symbioses are studied from several angles. The research first examines the development of implementation procedures for government bodies, academic institutions, and environmental consulting services. The purpose of the procedures is to create a dynamic of collaboration and trust between the economic players and the public officials in a region in order to identify potential industrial symbioses. The procedures necessitate managing large amounts of information about material and energy flows.Fieldwork conducted in the canton of Geneva and the Lausanne region, and used as case studies for the research, highlights a great number of industrial symbioses that already exist in French-speaking Switzerland. Several dozen examples are identified, primarily in the areas of water management, energy, chemical products, and building materials; however, Swiss law would permit many others. The research evaluates these opportunities from a technical, legal, economic, and environmental standpoint. By developing an assessment framework it is possible to determine which industrial symbioses are technically feasible and pertinent in Switzerland, and under what circumstances they would represent real added value compared to the current use of the resource and to existing systems for collecting and reusing waste.Lastly, SymbioGIS software was developed to help identify and assess potential industrial symbioses. The program's Web-based interface can be accessed by multiple users and is coupled with an interface that provides geographic information. In addition to identifying industrial symbioses, several program functionalities make it easier to consider material and energy flows with regard to local development issues and siting economic activities.In conclusion, the research highlights the need to bring together public institutions charged with protecting the environment, promoting economic activity, and overseeing development in order to foster the expansion of industrial symbioses as a strategy for managing material and energy resources. It proposes solutions for stepping up collaboration among these players and accelerating the sharing of knowledge about material and energy flows and their paths within economic activities with the goal of making theexisting industrial system in French-speaking Switzerland viable long-term. Also examined were thepossibilities of transposing these considerations and the study's findings about Switzerland to the economic and social context of the Asia-Pacific region, where much production is now located.

Geographic variation in the frequency of isolation and fluconazole and voriconazole susceptibilities of Candida glabrata: an assessment from the ARTEMIS DISK Global Antifungal Surveillance Program.

Geographic differences in frequency and azole resistance among Candida glabrata may impact empiric antifungal therapy choice. We examined geographic variation in isolation and azole susceptibility of C. glabrata. We examined 23 305 clinical isolates of C. glabrata during ARTEMIS DISK global surveillance. Susceptibility testing to fluconazole and voriconazole was assessed by disk diffusion, and the results were grouped by geographic location: North America (NA) (2470 isolates), Latin America (LA) (2039), Europe (EU) (12 439), Africa and the Middle East (AME) (728), and Asia-Pacific (AP) (5629). Overall, C. glabrata accounted for 11.6% of 201 653 isolates of Candida and varied as a proportion of all Candida isolated from 7.4% in LA to 21.1% in NA. Decreased susceptibility (S) to fluconazole was observed in all geographic regions and ranged from 62.8% in AME to 76.7% in LA. Variation in fluconazole susceptibility was observed within each region: AP (range, 50-100% S), AME (48-86.9%), EU (44.8-88%), LA (43-92%), and NA (74.5-91.6%). Voriconazole was more active than fluconazole (range, 82.3-84.2% S) with similar regional variation. Among 22 sentinel sites participating in ARTEMIS from 2001 through 2007 (84 140 total isolates, 8163 C. glabrata), the frequency of C. glabrata isolation increased in 14 sites and the frequency of fluconazole resistance (R) increased in 11 sites over the 7-year period of study. The sites with the highest cumulative rates of fluconazole R were in Poland (22% R), the Czech Republic (27% R), Venezuela (27% R), and Greece (33% R). C. glabrata was most often isolated from blood, normally sterile body fluids and urine. There is substantial geographic and institutional variation in both frequency of isolation and azole resistance among C. glabrata. Prompt species identification and fluconazole susceptibility testing are necessary to optimize therapy for invasive candidiasis.

National, regional, and global trends in fasting plasma glucose and diabetes prevalence since 1980: systematic analysis of health examination surveys and epidemiological studies with 370 country-years and 2·7 million participants.

BACKGROUND: Data for trends in glycaemia and diabetes prevalence are needed to understand the effects of diet and lifestyle within populations, assess the performance of interventions, and plan health services. No consistent and comparable global analysis of trends has been done. We estimated trends and their uncertainties in mean fasting plasma glucose (FPG) and diabetes prevalence for adults aged 25 years and older in 199 countries and territories. METHODS: We obtained data from health examination surveys and epidemiological studies (370 country-years and 2·7 million participants). We converted systematically between different glycaemic metrics. For each sex, we used a Bayesian hierarchical model to estimate mean FPG and its uncertainty by age, country, and year, accounting for whether a study was nationally, subnationally, or community representative. FINDINGS: In 2008, global age-standardised mean FPG was 5·50 mmol/L (95% uncertainty interval 5·37-5·63) for men and 5·42 mmol/L (5·29-5·54) for women, having risen by 0·07 mmol/L and 0·09 mmol/L per decade, respectively. Age-standardised adult diabetes prevalence was 9·8% (8·6-11·2) in men and 9·2% (8·0-10·5) in women in 2008, up from 8·3% (6·5-10·4) and 7·5% (5·8-9·6) in 1980. The number of people with diabetes increased from 153 (127-182) million in 1980, to 347 (314-382) million in 2008. We recorded almost no change in mean FPG in east and southeast Asia and central and eastern Europe. Oceania had the largest rise, and the highest mean FPG (6·09 mmol/L, 5·73-6·49 for men; 6·08 mmol/L, 5·72-6·46 for women) and diabetes prevalence (15·5%, 11·6-20·1 for men; and 15·9%, 12·1-20·5 for women) in 2008. Mean FPG and diabetes prevalence in 2008 were also high in south Asia, Latin America and the Caribbean, and central Asia, north Africa, and the Middle East. Mean FPG in 2008 was lowest in sub-Saharan Africa, east and southeast Asia, and high-income Asia-Pacific. In high-income subregions, western Europe had the smallest rise, 0·07 mmol/L per decade for men and 0·03 mmol/L per decade for women; North America had the largest rise, 0·18 mmol/L per decade for men and 0·14 mmol/L per decade for women. INTERPRETATION: Glycaemia and diabetes are rising globally, driven both by population growth and ageing and by increasing age-specific prevalences. Effective preventive interventions are needed, and health systems should prepare to detect and manage diabetes and its sequelae. FUNDING: Bill & Melinda Gates Foundation and WHO.

Freedom Trial First-Year Extension: Results from 4 Years of Denosumab Exposure in Women with Postmenopausal Osteoporosis

Aims: To investigate the long-term efficacy and safety of denosumab (DMAb) for the treatment of postmenopausal women with osteoporosis in an open-label extension to the 3-year FREEDOM study.1Methods: All women who completed the FREEDOM study were eligible to enter a long-term open-label extension (up to 10 years). After providing informed consent, participants received 6-monthly subcutaneous injections of DMAb (60 mg). Here we report data from the first year of followup. For women randomized to DMAb in the FREEDOM study ('long-term group'), this represents up to 48 months of DMAb exposure (eight 6-monthly injections). For those randomized to placebo ('de novo group') the data are from up to 12 months of exposure (two injections). All participants continued to take calcium (1 g) and vitamin D (≥400 IU) supplements daily. Changes in bone mineral density (BMD) and bone turnover markers (BTM) are reported for subjects enrolled in the extension. No formal statistical testing was planned for this interim report. P-values are descriptive.Results: Overall, 4,550 eligible women (70.2%) who completed the FREEDOM study entered the open-label extension study (long-term, n=2,343; de novo, n=2,207). During the first year of the extension, lumbar spine (LS) BMD in the long-term group further increased by 2.0% (12.1% increase vs. FREEDOM baseline at 48 months), and total hip (TH) BMD further increased by 0.8% (6.5% increase at 48 months) (p<0.0001 for both BMD gains during year 4; Fig. 1). During the first year of the extension, LS and TH BMD increased by 5.4% and 3.0%, respectively in the de novo group (both p<0.0001). After DMAb initiation, serum C-telopeptide (CTX) in the de novo group decreased rapidly and similarly to the long-term group (Fig. 2). Reductions in BTMs continue to attenuate at the end of the dosing interval as previously reported. Adverse event (AE) rates were similar (70.4% of women in the longterm group and 67.9% in the de novo group). Serious Aes were also similar (9.8% and 11.2% of women, respectively). During year 4, osteoporotic nonvertebral fractures were reported in 31 women in the long-term group and 51 in the denovo group.Fig. 1. Percentage change in BMD with denosumab for4 years (long-term) or 1 year (de novo)Fig. 2. Percentage change in sCTX over timeConclusions: These interim results suggest that continuation of DMAb treatment through 48 months is associated with further significant increases in spine and hip BMD with sustained reduction of bone turnover. The de-novo treatment group results confirm the first year active treatment findings previously reported1.Acknowledgements: Amgen Inc. sponsored this study.

Effect of a whey-predominant starter formula containing LCPUFAs and oligosaccharides (FOS/GOS) on gastrointestinal comfort in infants.

Development of new infant formulas aims to replicate the benefits of breast milk. One benefit of breast milk over infant formulas is greater gastrointestinal comfort. We compared indicators of gastrointestinal comfort in infants fed a whey-predominant formula containing long-chain polyunsaturated fatty acids, galacto-oligo-saccharides and fructo-oligosaccharides, and infants fed a control casein-predominant formula without additional ingredients. The single-centre, prospective, double-blind, controlled trial randomly assigned healthy, full-term infants (n=144) to receive exclusively either experimental or control formula from 30 days to 4 months of age. A group of exclusively breast-fed infants served as reference (n=80). At 1, 2, 3, and 4 months, infants' growth parameters were measured and their health assessed. Parents recorded frequency and physical characteristics of infants' stool, frequency of regurgitation, vomiting, crying and colic. At 2-months, gastric emptying (ultrasound) and intestinal transit time (H2 breath test) were measured, and stool samples collected for bacterial analysis. Compared to the control (n=69), fewer of the experimental group (n=67) had hard stools (0.7 vs 7.5%, p<0.001) and more had soft stools (90.8 vs 82.3%, p<0.05). Also compared to the control, the experimental group's stool microbiota composition (mean % bifidobacteria: 78.1 (experimental, n=17), 63.7 (control, n=16), 74.3 (breast-fed, n=20), gastric transit times (59.6 (experimental, n=53), 61.4 (control, n=62), 55.9 (breast-fed, n=67) minutes) and intestinal transit times (data not shown) were closer to that of the breast-fed group. Growth parameter values were similar for all groups. The data suggest that, in infants, the prebiotic-containing whey-based formula provides superior gastrointestinal comfort than a control formula.

New approach for weight reduction by a combination of diet, light resistance exercise and the timing of ingesting a protein supplement.

We have reported that ingesting a meal immediately after exercise increased skeletal muscle accretion and less adipose tissue accumulation in rats employed in a 10 week resistance exercise program. We hypothesized that a possible increase in the resting metabolic rate (RMR) as a result of the larger skeletal muscle mass might be responsible for the less adipose deposition. Therefore, the effect of the timing of a protein supplement after resistance exercise on body composition and the RMR was investigated in 17 slightly overweight men. The subjects participated in a 12-week weight reduction program consisting of mild energy restriction (17% energy intake reduction) and a light resistance exercise using a pair of dumbbells (3-5 kg). The subjects were assigned to two groups. Group S ingested a protein supplement (10 g protein, 7 g carbohydrate, 3.3 g fat and one-third of recommended daily allowance (RDA) of vitamins and minerals) immediately after exercise. Group C did not ingest the supplement. Daily intake of both energy and protein was equal between the two groups and the protein intake met the RDA. After 12 weeks, the bodyweight, skinfold thickness, girth of waist and hip and percentage bodyfat significantly decreased in the both groups, however, no significant differences were observed between the groups. The fat-free mass significantly decreased in C, whereas its decrease in S was not significant. The RMR and post-meal total energy output significantly increased in S, while these variables did not change in C. In addition, the urinary nitrogen excretion tended to increase in C but not in S. These results suggest that the RMR increase observed in S might be associated with an increase in body protein synthesis.

Peatlands and plantations in Sumatra, Indonesia : Complex realities for resource governance, rural development and climate change mitigation

Peatlands play a crucial role in Indonesia's economic development, and in its stated goal of reducing greenhouse gas emissions. Improved peatland management - including a national moratorium on the granting of any new conversion licenses - forms a cornerstone of Indonesia's climate change mitigation commitment. At the same time, rapid expansion of the plantation sector is driving wide-scale drainage and conversion of peat swamp ecosystems. The province of Riau, in central Sumatra, finds itself at the crossroads of these conflicting agendas. This essay presents a case study of three islands on Riau's east coast affected by industrial timber plantation concessions. It examines the divergent experiences, perceptions and responses of communities on the islands. A mix of dramatic protests, localised everyday actions and constructive dialogue has succeeded in delaying or perhaps halting one of the concessions, while negotiations and contestation with the other two continue. With the support of regional and national non-governmental organisations and local government, communities are pursuing alternative development strategies, including the cultivation of sago, which requires no peat drainage. While a powerful political economy of state and corporate actors shapes the contours of socio-environmental change, local social movements can alter trajectories of change, promoting incremental improvements and alternative pathways.

Genetic structure of Gymnures (genus Hylomys; Erinaceidae) on continental islands of Southeast Asia: Historical effects of fragmentation

Eustatic sea level changes during Pleistocene climatic fluctuations produced several cycles of connection-isolation among continental islands of the Sunda shelf. To explore the potential effects of these fluctuations, we reconstructed a model of the vicariant events that separated these islands, based on bathymetric information. Among many possible scenarios, two opposite phylogenetic patterns of evolution were predicted for terrestrial organisms living in this region: one is based on the classical allopatric speciation mode of evolution, while the other is the outcome of a sequential dispersal colonization of the archipelago. We tested the applicability of these predictions with an analysis of sequence variation of the cytochrome b gene from several taxa of Hylomys. They were sampled throughout SE-Asia and the Sunda islands. High levels of haplotype differentiation characterize the different island taxa. Such levels of differentiation support the existence of several allopatric species, as was suggested by previous allozyme and morphological data. Also in accordance with previous results, the occurrence of two sympatric species from Sumatra is suggested by their strongly divergent haplotypes. One species, Hylomys suillus maxi, is found both on Sumatra and in Peninsular Malaysia, while the other, H. parvus, is endemic to Sumatra. Its closest relative is H. suillus dorsalis from Borneo. Phylogenetic reconstructions also demonstrate the existence of a Sundaic clade composed of all island taxa, as opposed to those from the continent. Although there is no statistical support for either proposed biogeographic model of evolution, we argue that the sequential dispersal scenario is more appropriate to describe the genetic variation found among the Hylomys taxa. However, despite strong differentiation among island haplotypes, the cladistic relationships between some island taxa could not be resolved. We argue that this is evidence of a rapid radiation, suggesting that the separation of the islands may have been perceived as a simultaneous event rather than as a succession of vicariant events. Furthermore, the estimates of divergence times between the haplotypes of these taxa suggest that this radiation may actually have predated the climatic fluctuations of the Pleistocene. Further refinement of the initial palaeogeographic models of evolution are therefore needed to account for these results.

Global alcohol exposure estimates by country, territory and region for 2005--a contribution to the Comparative Risk Assessment for the 2010 Global Burden of Disease Study.

AIMS: This study aimed to estimate the prevalence of life-time abstainers, former drinkers and current drinkers, adult per-capita consumption of alcohol and pattern of drinking scores, by country and Global Burden of Disease region for 2005, and to forecast these indicators for 2010. DESIGN: Statistical modelling based on survey data and routine statistics. SETTING AND PARTICIPANTS: A total of 241 countries and territories. MEASUREMENTS: Per-capita consumption data were obtained with the help of the World Health Organization's Global Information System on Alcohol and Health. Drinking status data were obtained from Gender, Alcohol and Culture: An International Study, the STEPwise approach to Surveillance study, the World Health Survey/Multi-Country Study and other surveys. Consumption and drinking status data were triangulated to estimate alcohol consumption across multiple categories. FINDINGS: In 2005 adult per-capita annual consumption of alcohol was 6.1 litres, with 1.7 litres stemming from unrecorded consumption; 17.1 litres of alcohol were consumed per drinker, 45.8% of all adults were life-time abstainers, 13.6% were former drinkers and 40.6% were current drinkers. Life-time abstention was most prevalent in North Africa/Middle East and South Asia. Eastern Europe and Southern sub-Saharan Africa had the most detrimental pattern of drinking scores, while drinkers in Europe (Eastern and Central) and sub-Saharan Africa (Southern and West) consumed the most alcohol. CONCLUSIONS: Just over 40% of the world's adult population consumes alcohol and the average consumption per drinker is 17.1 litres per year. However, the prevalence of abstention, level of alcohol consumption and patterns of drinking vary widely across regions of the world.

Proto-South-East Asia as a trigger of early angiosperm diversification

Darwin described as an 'abominable mystery' the abrupt origin of angiosperms in the mid-Cretaceous and the high diversification rates in their early history. The father of evolutionary theory could not fathom this rapid diversification and rather invoked that 'there was during long ages a small isolated continent in the S. hemisphere, which served as the birthplace of the higher plants'. In this essay, we comment on the spatial origin of angiosperms, but focus primarily on understanding the abiotic factors that promoted the early diversification of angiosperms by reviewing palaeobotanical, palaeogeographical, phylogenetics and biogeographical evidence. We argue that islands located in the region today occupied by South-East Asia played a major role in angiosperm diversification during the Late Jurassic and Early Cretaceous.

Note on seismic hazard assessment using gradient of uplift velocities on the Turan Block (Central Asia)

Uplift gradients can provide the location of highly strained zones, which can be considered to be seismic. The Turan block (Central Asia) contains zones with high gradient of uplift velocities, above the threshold 0.04mm km-1year-1. Some of these zones are associated with important seismic activity and others are not correlated with any recent important recorded earthquakes, however, recent faults scarps as well as diverted rivers may indicate a recent tectonic activity. This threshold of gradient is probably a significant rheologic property of the upper crust. On the basis of these considerations the Uzboy river area is proposed as a potential high seismic hazard zone.
