India needs to balance carbon mitigation with its developmental priorities. The Indian district acts as an important administrative site where national- and state-level developmental and environmental policies are translated into ground-level implementation. In this work, we provide a replicable approach to analyze the evolution of district-level carbon emissions in near real-time. Our work shows that emissions are concentrated in a small number of districts, with this concentration increasing over time. We also find significant inter-district variation in the growth of emissions. We demonstrate the utility of high-resolution emissions data through three examples.
Technical summary.
With India accounting for a growing share of world emissions, the country's carbon emissions trajectory is important from a global mitigation perspective. At the same time, India is simultaneously attempting to achieve both environmental and developmental goals. The district acts as an administrative site that is important for India's future trajectory, as developmental and environmental policies at the national and state levels get translated to actual implementation at the district level. In this work, we study the evolution of carbon emissions at the district level in India. We rely on the GRACED dataset that provides daily emissions information for various sectors at a spatial resolution of 0.1°. We find that 7% of districts account for ∼50% of total emissions, while the bottom 50% contribute less than 9%. This spatial concentration is intensifying over time. We also document variations in the contribution of different sectors to total emissions over the year. We demonstrate the utility of high-resolution emissions data through three examples. Our approach can aid researchers and policymakers in developing targeted interventions as it is easily replicable, goes beyond existing work in its spatial and temporal resolution, and can be adapted to study district emissions in near-real time.

This article argues that public interests fundamentally underpin the decision-making processes of the European supervisory authorities in the banking system and, through their extraordinary regulatory influence, contribute to shaping the discretionary powers, orienting them towards an adequate and effective legal protection of the individual and collective subjective spheres, whose interests are embodied in the legal sources and principles of the European legal order. The case of the European Banking Authority reflects this conceptual framework and could serve as a benchmark for European banking law.
For a certain class of real analytic varieties with Lie group actions, we develop a theory of (free-monodromic) tilting sheaves, and apply it to flag varieties stratified by real group orbits. For quasi-split real groups, we construct a fully faithful embedding of the category of tilting sheaves to a real analog of the category of Soergel bimodules, establishing real group analogs of Soergel’s structure theorem and the endomorphism theorem. We apply these results to give a purely geometric proof of the main result of Bezrukavnikov and Vilonen [Koszul duality for quasi-split real groups, Invent. Math. 226 (2021), 139–193], which proves Soergel’s conjecture [Langlands’ philosophy and Koszul duality, in Algebra – representation theory (Constanta, 2000), NATO Science Series II: Mathematics, Physics and Chemistry, vol. 28 (Kluwer Academic Publishers, Dordrecht, 2001), 379–414] for quasi-split groups.
Scholars almost universally identify “the great multitude that no one could count from every nation, from all tribes and peoples and languages” (Rev 7:9) as a multi-ethnic gathering of the nations. However, this language could also describe a regathered twelve tribes of Israel taken out from the places where they had been scattered among the nations. Such a referent is plausible because of the widespread belief in the continued existence of the twelve tribes and the persistent hope of their regathering. It can also better account for the vision’s pervasive echoes of the repatriation theme from Israel’s ancestral writings (7:9–17) and the preceding vision’s enumeration of the 144,000 from all the tribes of Israel (7:4–8)—widely understood to be the same group as the innumerable multitude. If this referent is correct, it suggests that the New Jerusalem (21:1–22:5) is also populated by a restored Israel.
This forum engages an emerging discourse around historical reckoning, truth, and reconciliation, asking how these frameworks inform American archaeology and its future. A growing number of archaeologists are now demanding systemic disciplinary transformations that directly address how white supremacy and settler colonialism enact Indigenous dispossession and erasure as well as anti-Blackness, gender discrimination, and ableism. This forum, featuring 10 archaeologists—including a mixture of junior- and senior-level scholars—is organized into thematic dialogues that highlight their different perspectives and experiences within North American cultural heritage management. First, the dialogue interrogates American archaeology’s embeddedness in ethnocentrism and racism. It then looks at different forms of collaboration that actualize anti-colonial critiques and corrections. Next, it compares collaborative methods with broader calls for “un-disciplining” through incorporating non-Western expertise, sensibilities, needs, and interests. In response to systemic forms of racism, colonialism, and neoliberalism within archaeology, the authors discuss how individuals and institutions can work for and with Indigenous and descendant communities to achieve “reclamation,” defined as the assertion of community control over their significant places, ancestors, belongings, and historical narratives. The article concludes with a consideration of how archaeology can be used by communities to ensure their collective futures.
Biological invasions can impact the dynamics of ecological processes. For primates of the genus Callithrix, congeneric introductions and hybridization are one of the greatest threats to native species. Three species of Callithrix have been recorded in Rio Doce State Park in south-east Brazil: the Endangered native buffy-tufted-ear marmoset Callithrix aurita and two introduced marmosets, the Geoffroy’s tufted-ear marmoset Callithrix geoffroyi and the black-pencilled marmoset Callithrix penicillata, but their relative abundance was unknown. We used the call playback method and adapted N-mixture models to estimate the abundance and of these marmosets in relation to canopy cover, tree circumference, tree density, number of lianas and epiphytes per tree, distances to nearest forest edge, road, tourist area and urban area, and detection probability in relation to survey effort, mean daily precipitation and temperature. We recorded 139 individuals (0.12 individuals/ha), all hybrids except for one C. aurita. Marmoset abundance was higher close to the forest edge, possibly as a result of the greater availability of food and shelter there. Detection probability was positively correlated with daily precipitation, most probably because marmosets foraged more actively when humidity was high. The situation in Rio Doce State Park is critical, with high hybridization levels and potential local extinction of C. aurita. We recommend that a management plan to conserve the remaining C. aurita is implemented urgently.
The transition in welfare states from compensatory to service-oriented models also implies a shift of the locus of action from the state to local administrations. Cities in particular seek space within national bounds to devise their own policy solutions targeted to city-specific needs as a more responsive government layer, with the prospect of providing more targeted service provision on the basis of locality and proximity principles. Whether such social innovation potential is met depends on scope conditions, such as the learning environment, the design of the decentralisation and the capacity of cities to scale up smaller projects. In this paper, we trace the policy process around local social investment innovations in Amsterdam across three domains: addressing teacher shortages, combatting energy poverty and integrating the long-term unemployed into the labour market. In each of the domains, Amsterdam emerged as a frontrunner and innovator, instigating broader change. The city is at the frontier of societal change and acts as ‘a stopgap’, filling gaps left by national policy default. Overall, the case of Amsterdam shows the importance in adopting a multi-level perspective in studying new dynamics in welfare state transitions.
We report the rediscovery of two endemic tree species of the genus Myrcia (Myrtaceae) in the Brazilian Atlantic Forest in 2021–2022. Both Myrcia colpodes and Myrcia rubiginosa were previously known from a small number of specimens collected mostly in the 19th century in the Metropolitan Region of Rio de Janeiro state in Brazil. Living specimens had not been recorded since 1958 and 2005, respectively. We provide here photographic documentation and updated risk assessments for both species, which will be submitted to IUCN for a formal assessment. Our findings illustrate that rare species that have not been collected for long periods can sometimes be found in plain sight in urban forest fragments. We also highlight the importance of protected areas for the conservation of forest trees, in particular rediscovered species. We recommend a number of conservation actions and encourage the Brazilian government, scientific institutions and civil society to acknowledge the importance of these species and to act to safeguard their future.
A Pell–Abel equation is a functional equation of the form $P^{2}-DQ^{2} = 1$, with a given polynomial $D$ free of squares and unknown polynomials $P$ and $Q$. We show that the space of Pell–Abel equations with the degrees of $D$ and of the primitive solution $P$ fixed is a complex manifold. We describe its connected components by an efficiently computable invariant. Moreover, we give various applications of this result, including to torsion pairs on hyperelliptic curves and to Hurwitz spaces, and a description of the connected components of the space of primitive $k$-differentials with a unique zero on genus $2$ Riemann surfaces.
Although manuscripts are, literally, old media, they are also breaking news. This article reports from a study of scholars of ancient religions’ experiences with media engagement concerning manuscript finds and forgeries. Inspired by a mediatization-of-science perspective, the study explores the motivations for and involvement in public-facing scholarship, as well as the experienced effects of and reactions to their media exposure. Focusing on the challenges of media publicity in particular, the study discusses how the current impact and publicity agenda of contemporary universities affects individual academics.
The findings of this article are based on interviews with a sample of experts who, during the last twenty-five years, have shared their expertise in public-facing media outlets about the Gospel of Judas, the Hazon Gabriel tablet, the Jehoash inscription, the post-2002 Dead Sea Scrolls-like fragments, the so-called Gospel of Jesus’s Wife, the Sappho papyri, and the manuscript purchases of the Museum of the Bible in Washington, D.C.
Guaman Poma does not need to be presented as a superhero to highlight his place in history as the author of a codex containing a protest, a proposal, and a history of the Andes. Indeed, the case of Guaman Poma must be understood in its historical context, as it has been studied since its publication in Paris almost a century ago, in 1936. Thanks to rigorous studies by scholars from many countries, we are increasingly learning more about the author and his work, concluding that this is a completely plausible case—a product of the circumstances in which he lived, was formed, and developed over several decades during the consolidation of the colonial regime in the Andes.
