Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

Turning the carbon supertanker: Sectoral feasibility of climate change mitigation in China

Whether China can slow the growth of emissions of greenhouse gases and ultimately reduce them has become a central question for climate mitigation. In previous research on India, we developed a theoretical framework to assess the structural characteristics of different sectors and identify which ones were most amenable to mitigation. In this article, we extend that approach to China and review the nine sectors responsible for most of the country's emissions. These include electricity (disaggregating renewables, nuclear, and coal), road transportation, four disaggregated industry sub-sectors (steel, cement, fertilizers, and oil refining), and buildings. We identify two sets of attributes, what we called political/organizational feasibility and techno-economic feasibility, that together shape the possibilities for emissions mitigation. Our central intuition is that fragmentation - on the government or market side or both - makes collective action more difficult. Cement, steel, and oil refining possess favorable characteristics on both political/organizational feasibility and techno-economic feasibility, while fertilizers and renewables pose the most difficult challenges on both dimensions. Buildings and road transport are mixed cases, where techno-economic feasibility is high while political/organizational dynamics are more challenging. Finally, coal and nuclear are mixed cases where political/organizational feasibility is high but techno-economic aspects are more challenging

Tourists’ perspectives on hard and soft services toward rural tourism destination competitiveness: Community support as a moderator

Rural tourism is an integrated part in the services field, and this industry has long been recognized as a valuable tool for economic development in rural destinations. However, the multiplying growth of rural tourism destinations has led to a stiff competition among the industry. Thus, the identification of tourists’ perspective on the hard and soft services components toward the development of rural tourism is a key element in surviving into the rapid tourism competition. The pivotal role of community support as an integral part of tourism product in ensuring sustainable development of rural tourism destination would also being the key indicator for the development of rural tourism. Hence, this study highlighted the importance of tourists’ perspective on hard services (tourism infrastructure and accommodation) and soft services (range of activities and special events) toward the competitiveness of rural tourism destination’s development with community support who act as a moderator. A total of 314 respondents comprising tourists who visited Kampung Semadang, Kampung Telaga Air, and Kubah National Park (Kampung Matang), Kuching, Sarawak has voluntarily participated in this study. To assess the developed model, SmartPLS 2.0 (M3) is applied based on path modeling and bootstrapping. Interestingly, the findings revealed that tourists are more concerned about the quality of accommodation, infrastructure, range of activities, and special events for the development of tourism destination competitiveness in rural tourism destination. In addition, tourists also believed that the existence of community support is crucial in moderating the relationship between accommodation quality and tourism destination competitiveness. This study further discussed on the implications of the findings, limitations, and directions for future research

The ICD-11 developmental field study of reliability of diagnoses of high-burden mental disorders: results among adult patients in mental health settings of 13 countries

Reliable, clinically useful, and globally applicable diagnostic classification of mental disorders is an essential foundation for global mental health. The World Health Organization (WHO) is nearing completion of the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11). The present study assessed inter-diagnostician reliability of mental disorders accounting for the greatest proportion of global disease burden and the highest levels of service utilization – schizophrenia and other primary psychotic disorders, mood disorders, anxiety and fear-related disorders, and disorders specifically associated with stress – among adult patients presenting for treatment at 28 participating centers in 13 countries. A concurrent joint-rater design was used, focusing specifically on whether two clinicians, relying on the same clinical information, agreed on the diagnosis when separately applying the ICD-11 diagnostic guidelines. A total of 1,806 patients were assessed by 339 clinicians in the local language. Intraclass kappa coefficients for diagnoses weighted by site and study prevalence ranged from 0.45 (dysthymic disorder) to 0.88 (social anxiety disorder) and would be considered moderate to almost perfect for all diagnoses. Overall, the reliability of the ICD-11 diagnostic guidelines was superior to that previously reported for equivalent ICD-10 guidelines. These data provide support for the suitability of the ICD-11 diagnostic guidelines for implementation at a global level. The findings will inform further revision of the ICD-11 diagnostic guidelines prior to their publication and the development of programs to support professional training and implementation of the ICD-11 by WHO member states

Family burden related to mental and physical disorders in the world:results from the WHO World Mental Health (WMH) surveys

<p>Objective: To assess prevalence and correlates of family caregiver burdens associated with mental and physical conditions worldwide.</p><p>Methods: Cross-sectional community surveys asked 43,732 adults residing in 19 countries of the WHO World Mental Health (WMH) Surveys about chronic physical and mental health conditions of first-degree relatives and associated objective (time, financial) and subjective (distress, embarrassment) burdens. Magnitudes and associations of burden are examined by kinship status and family health problem; population-level estimates are provided.</p><p>Results: Among the 18.9-40.3% of respondents in high, upper-middle, and low/lower-middle income countries with first-degree relatives having serious health problems, 39.0-39.6% reported burden. Among those, 22.9-31.1% devoted time, 10.6-18.8% had financial burden, 23.3-27.1% reported psychological distress, and 6.0-17.2% embarrassment. Mean caregiving hours/week was 12.9-16.5 (83.7-147.9 hours/week/100 people aged 18+). Mean financial burden was 15.1% of median family income in high, 32.2% in upper-middle, and 44.1% in low/lower-middle income countries. A higher burden was reported by women than men, and for care of parents, spouses, and children than siblings.</p><p>Conclusions: The uncompensated labor of family caregivers is associated with substantial objective and subjective burden worldwide. Given the growing public health importance of the family caregiving system, it is vital to develop effective interventions that support family caregivers.</p>
