Abstract A search has been made for events containing an energetic jet and an imbalance in transverse momentum using a data sample of pp collisions at a center-of-mass energy of 7 TeV. This signature is common to both dark matter and extra dimensions models. The data were collected by the CMS detector at the LHC and correspond to an integrated luminosity of 5.0 fb−1. The number of observed events is consistent with the standard model expectation. Constraints on the dark matter-nucleon scattering cross sections are determined for both spin-independent and spin-dependent interaction models. For the spin-independent model, these are the most constraining limits for a dark matter particle with mass below 3.5 GeV/c 2, a region unexplored by direct detection experiments. For the spin-dependent model, these are the most stringent constraints over the 0.1–200 GeV/c 2 mass range. The constraints on the Arkani-Hamed, Dimopoulos, and Dvali model parameter M D determined as a function of the number of extra dimensions are also an improvement over the previous results.

Abstract The traditional use of land for food, fuel and wood created cultural landscapes, which are threatened across Europe. The factors which contributed to their endangerment need to be identified to achieve effective preservation of such landscapes. The aim of our study was to identify landscapes with historical persistence in a GIS-based comparative analysis of historical and contemporary maps and the most prominent causes of the past landscape changes, based on stakeholders' perspective. We considered a case study in Romania's Carpathians. Three major land cover types were extracted from maps dating from 1912, 1980 and 2009: built-up, pastures and forests. The historical persistence of all land cover types was poor (

Sustainable energy consumption is a research area of a large interest in the last years. New energy-efficient lighting technologies exist, and can significantly reduce household electricity consumption, but their adoption has been slow. A considerable number of international studies show that sustainable development scenarios will be realistic if they involve the human behavior. The paper provides a solution to integrate consumer behavior with techno-economic energy issues, inside a complex energy model. This approach aims to reduce the systematic error on the demand side of the energy model that stems from the hypotheses of perfect information and of perfect economic rationality. These hypotheses are common to all optimization models based on the concept of economic equilibria. The TIMES energy modeling software tool has been used to integrate the techno-economic energy specific data and consumer behavior. Consumer behavior in energy consumption is described using specific attributes of energy technologies as virtual technologies. Technical coefficients of virtual technologies come from a sociological survey about Romanians’ behavior in energy consumption. This approach, known as “Social MARKAL”, allows the analyst to evaluate the possible contribution of information campaigns in changing lighting consumers’ behavior and effect of technology switch. The model is developed for the period 2010-2026, and is implemented by using TIMES/VEDA software platform. The implementation presented this paper focuses on the household lighting technologies but the approach can be extended to other demand sectors as well.

La promesse d'une coproduction pour relever des défis complexes en matière de durabilité est convaincante. Pourtant, la coproduction, le tissage collaboratif de la recherche et de la pratique, englobe divers objectifs, terminologies et pratiques, avec peu de clarté sur leurs implications. Pour explorer cette diversité, nous avons systématiquement cartographié les différences dans la façon dont 32 initiatives de 6 continents coproduisent divers résultats pour le développement durable des écosystèmes à l'échelle locale et mondiale. Nous avons constaté des variations dans leur objectif d'utilisation de la coproduction, de compréhension du pouvoir, d'approche de la politique et de voies d'impact. Une analyse par grappes a identifié six modes de coproduction : (1) la recherche de solutions ; (2) l'autonomisation des voix ; (3) le pouvoir de courtage ; (4) le pouvoir de recadrage ; (5) la gestion des différences et (6) l'agence de recadrage. Aucun mode n'est idéal ; chacun possède un potentiel unique pour atteindre des résultats particuliers, mais pose également des défis et des risques uniques. Notre analyse fournit un outil heuristique aux chercheurs et aux acteurs de la société pour explorer de manière critique cette diversité et naviguer efficacement dans les compromis lors de la coproduction de la durabilité. La coproduction comprend divers objectifs, terminologies et pratiques. Cette étude explore cette diversité en cartographiant les différences dans la façon dont 32 initiatives de 6 continents coproduisent divers résultats pour le développement durable des écosystèmes à l'échelle locale et mondiale. La promesa de la coproducción para abordar los complejos desafíos de sostenibilidad es convincente. Sin embargo, la coproducción, el tejido colaborativo de la investigación y la práctica, abarca diversos objetivos, terminologías y prácticas, con poca claridad sobre sus implicaciones. Para explorar esta diversidad, mapeamos sistemáticamente las diferencias en cómo 32 iniciativas de 6 continentes coproducen diversos resultados para el desarrollo sostenible de los ecosistemas a escala local y global. Encontramos variaciones en su propósito de utilizar la coproducción, la comprensión del poder, el enfoque de la política y los caminos hacia el impacto. Un análisis de clústeres identificó seis modos de coproducción: (1) investigar soluciones; (2) empoderar las voces; (3) poder de intermediación; (4) poder de replanteamiento; (5) navegar las diferencias y (6) replantear la agencia. Ningún modo es ideal; cada uno tiene un potencial único para lograr resultados particulares, pero también plantea desafíos y riesgos únicos. Nuestro análisis proporciona una herramienta heurística para que los investigadores y los actores sociales exploren críticamente esta diversidad y naveguen eficazmente por las compensaciones al coproducir sostenibilidad. La coproducción incluye diversos objetivos, terminologías y prácticas. Este estudio explora dicha diversidad mediante el mapeo de las diferencias en la forma en que 32 iniciativas de 6 continentes coproducen diversos resultados para el desarrollo sostenible de los ecosistemas a escala local y global. The promise of co-production to address complex sustainability challenges is compelling. Yet, co-production, the collaborative weaving of research and practice, encompasses diverse aims, terminologies and practices, with poor clarity over their implications. To explore this diversity, we systematically mapped differences in how 32 initiatives from 6 continents co-produce diverse outcomes for the sustainable development of ecosystems at local to global scales. We found variation in their purpose for utilizing co-production, understanding of power, approach to politics and pathways to impact. A cluster analysis identified six modes of co-production: (1) researching solutions; (2) empowering voices; (3) brokering power; (4) reframing power; (5) navigating differences and (6) reframing agency. No mode is ideal; each holds unique potential to achieve particular outcomes, but also poses unique challenges and risks. Our analysis provides a heuristic tool for researchers and societal actors to critically explore this diversity and effectively navigate trade-offs when co-producing sustainability. Co-production includes diverse aims, terminologies and practices. This study explores such diversity by mapping differences in how 32 initiatives from 6 continents co-produce diverse outcomes for the sustainable development of ecosystems at local to global scales. إن الوعد بالإنتاج المشترك لمواجهة تحديات الاستدامة المعقدة أمر مقنع. ومع ذلك، فإن الإنتاج المشترك، وهو النسيج التعاوني للبحث والممارسة، يشمل أهدافًا ومصطلحات وممارسات متنوعة، مع ضعف الوضوح بشأن آثارها. لاستكشاف هذا التنوع، قمنا بشكل منهجي بتحديد الاختلافات في كيفية مشاركة 32 مبادرة من 6 قارات في إنتاج نتائج متنوعة للتنمية المستدامة للنظم الإيكولوجية على المستويات المحلية إلى العالمية. وجدنا تباينًا في غرضهم من استخدام الإنتاج المشترك وفهم القوة ونهج السياسة ومسارات التأثير. حدد تحليل عنقودي ستة أنماط للإنتاج المشترك: (1) حلول البحث ؛ (2) تمكين الأصوات ؛ (3) قوة الوساطة ؛ (4) قوة إعادة الصياغة ؛ (5) التنقل في الاختلافات و (6) وكالة إعادة الصياغة. لا يوجد وضع مثالي ؛ يحمل كل منها إمكانات فريدة لتحقيق نتائج معينة، ولكنه يشكل أيضًا تحديات ومخاطر فريدة. يوفر تحليلنا أداة إرشادية للباحثين والجهات الفاعلة المجتمعية لاستكشاف هذا التنوع بشكل نقدي والتنقل بفعالية في المفاضلات عند المشاركة في إنتاج الاستدامة. يتضمن الإنتاج المشترك أهدافًا ومصطلحات وممارسات متنوعة. تستكشف هذه الدراسة هذا التنوع من خلال تحديد الاختلافات في كيفية مشاركة 32 مبادرة من 6 قارات في إنتاج نتائج متنوعة للتنمية المستدامة للنظم الإيكولوجية على المستويات المحلية إلى العالمية.

AbstractOlder adults are generally amongst the most vulnerable to heat and cold. While temperature-related health impacts are projected to increase with global warming, the influence of population aging on these trends remains unclear. Here we show that at 1.5 °C, 2 °C, and 3 °C of global warming, heat-related mortality in 800 locations across 50 countries/areas will increase by 0.5%, 1.0%, and 2.5%, respectively; among which 1 in 5 to 1 in 4 heat-related deaths can be attributed to population aging. Despite a projected decrease in cold-related mortality due to progressive warming alone, population aging will mostly counteract this trend, leading to a net increase in cold-related mortality by 0.1%–0.4% at 1.5–3 °C global warming. Our findings indicate that population aging constitutes a crucial driver for future heat- and cold-related deaths, with increasing mortality burden for both heat and cold due to the aging population.
