We discuss the relative log minimal model theory for log surfaces in the analytic setting. More precisely, we show that the minimal model program, the abundance theorem, and the finite generation of log canonical rings hold for log pairs of complex surfaces which are projective over complex analytic varieties.

For a finite extension F of ${\mathbb Q}_p$ and $n \geq 1$, we show that the category of Lubin-Tate bundles on the $(n-1)$-dimensional Drinfeld symmetric space is equivalent to the category of finite-dimensional smooth representations of the group of units of the division algebra of invariant $1/n$ over F.

This article invites readers to examine water as an active force in U.S. history rather than a backdrop to national development. Complementing traditional historiographies and drawing on blue humanities, we reframe national narratives by linking the country’s oceanic reach to domestic hydrology and imperial expansion, positioning the United States as a key driver and emblematic case of the “blue acceleration.” A water-centered lens reveals how water availability and management extended state power, created sacrifice zones, fostered uneven development, and continue to test American democracy. The essay offers a conceptual map for reimagining the U.S. past and human–water relations in a warming world.

Distributive justice preferences are important because they can influence the policy orientations of political actors and can help create conditions conducive to policy change. Yet, these preferences have received relatively little scholarly attention in countries that are not included in major cross-country surveys such as Turkey. This article examines Turkish distributive justice preferences across four key social policy sectors: education; healthcare; old-age pensions; and unemployment insurance. The analysis draws on 2019 data from an original nationwide survey (n = 2,272), designed by a research team including the authors and implemented by a professional survey firm using multistage stratified random sampling. Our findings confirm that, as in mature welfare states, distributive justice preferences vary across social policy sectors in the Turkish case. However, the equality principle is strongly favored in three of the four areas, while equity is preferred only in old-age pensions, possibly reflecting policy feedback effects. In the context of high inequality and low social and institutional trust, we introduce distrustful egalitarianism as a concept to capture egalitarian preferences driven more by distrust of official allocation mechanisms than by purely ideological commitments to equality. These findings highlight the need for further research in middle-income countries with less mature welfare systems.

A disrupting plasma in a high-performance tokamak such as ITER or SPARC may generate large runaway electron currents that, upon impact with the tokamak wall, can cause serious damage to the device. To quickly identify regions of safe operation in parameter space, it is useful to develop reduced models and analytical criteria that predict when a significant fraction of the Ohmic current is converted into a current of runaway electrons. In deuterium–tritium plasmas, the seed runaway current may have a significant contribution from – or may even be dominated by – tritium beta decay and Compton scattering. In this work, a criterion for significant runaway electron generation that includes tritium beta decay and Compton scattering sources is developed. The avalanche gain factor includes the effects of partial screening of injected noble gases. The result is an analytical model that can predict significant runaway electron generation in the next generation of activated tokamak devices. The model is validated by fluid simulations using Dream (Hoppe et al. 2021 Comput. Phys. Commun., vol. 268, p. 108098) and is shown to delineate regions in parameter space where significant runaway electron generation may occur.

Mexico ranks third globally in seabird diversity and second in the number of endemic species that breed within its territory, yet 16% of seabird species in the country are categorized as threatened on the IUCN Red List, including the Critically Endangered Townsend’s shearwater Puffinus auricularis. Nearly 20 years ago, the breeding population of Townsend’s shearwater, which is endemic to the Revillagigedo Archipelago of Mexico, was inferred to comprise < 100 breeding pairs. Since then, conservation initiatives have been implemented in the archipelago. We assessed the current status of Townsend’s shearwater by mapping the distribution of breeding colonies, estimating breeding population size, evaluating reproductive success, describing ongoing threats and modelling population trends under three conservation scenarios. During 2016–2024, we conducted field surveys on the islands of Socorro and Clarión using acoustic monitoring techniques in historical nesting areas. We estimated that the breeding population on Socorro comprises < 200 pairs and documented the return of a small breeding population to Clarión after a 30-year absence. However, reproductive failure persists because of the effects of native predators such as land crabs, snakes and ravens. The population has exhibited a slow decline driven by interactions between native and invasive species. Without ongoing restoration efforts and management actions, including the removal of feral cats, the population could face extinction.

The COVID-19 pandemic brought about changes to almost every aspect of life. Courts were no exception, with the pandemic dramatically increasing the use of virtual court hearings. This paper explores virtual hearings and their impact on therapeutic approaches to judging, which prioritise connection and engagement between judicial officers and participants. While particularly drawing on the experience in Australia and the United Kingdom, the paper draws on broader international research to identify the potential challenges of seeking to conduct therapeutic judging online, but also areas where the virtual environment might improve participants’ therapeutic experience. Further research on this topic is likely to be fruitful, as virtual court hearings become a more entrenched part of court practice. We therefore canvass areas for future research, to enhance the therapeutic potential of the judicial role in a virtual environment.

The two-boost problem in space mission design asks whether two points of phase space can be connected with the help of two boosts of given energy. We provide a positive answer for a class of systems having a similar behaviour at infinity as the restricted three-body problem by defining and computing its Lagrangian Rabinowitz Floer homology. The principal technical challenge is dealing with the non-compactness of the associated energy hypersurfaces.

Widely found at archaeological sites across the Roman Empire, the appearance in the late 1st c. BCE onward of the red gloss ceramic referred to as terra sigillata signals important transformations in the socio-economic organization of production and consumption for provincial societies. Nonetheless, relatively few studies have explored diachronically the ways in which the appearance of terra sigillata may have impacted local lifeways compared with the uses of earlier ceramics. This article explores these issues in the context of Roman Mediterranean Gaul, focusing in particular on the region of eastern Languedoc, by comparing, in both discard and funerary contexts, the differential uses of black gloss ceramics from the 3rd to the 1st c. BCE with later terra sigillata vessels. The evidence discussed here suggests that the appearance of terra sigillata was important in reifying more individual-centered social relationships in dining and other aspects of daily life.

This article investigates how autocratizing regimes instrumentalize the cultural domain to manufacture consent, assert societal dominance, and socialize oppositional actors into authoritarian logics. In contexts of competitive authoritarianism, memory politics becomes central not only to the incumbent’s efforts to legitimize power and construct hegemonic narratives of citizenship, identity, and history, but also to the opposition’s attempts to propose alternatives. Drawing on fieldwork, curator interviews, and audience responses, the article analyzes two large-scale centennial exhibitions held in İstanbul in 2023 and 2024 that offer contrasting portrayals of the Turkish Republic – one Islamist–authoritarian, the other liberal–Kemalist. Despite clear ideological differences, divergent aesthetic approaches, and distinct target audiences, both exhibitions rely on exclusionary, state-centric framings that inhibit critical or pluralist engagements with the past. The article argues that this convergence signals a deeper transformation: the autocratization of the cultural field, wherein even oppositional institutions internalize authoritarian norms and practices. In this context, history is staged as spectacle – either triumphant or nostalgic – narrowing the cultural imagination, consolidating incumbent power, and diminishing spaces for meaningful contestation.

Recent research highlights the crisis-driven approach for regional institution-building, suggesting that crises enhance the utility of regionalism. This study questions the applicability of crisis-driven regionalism in Northeast Asia, emphasising why certain crises catalyse regionalist efforts while others do not. We clarify the working mechanisms of critical juncture approaches and identify three variables influencing the effectiveness of crisis-driven regionalism, each operating at different stages – pre-crisis, in-crisis, and post-crisis. First, exogenous crises are more likely to trigger cooperation than endogenous ones, as the latter provoke disputes over the origins and responsibilities of the crisis. Second, crises should foster collective action and shared agendas among states, rather than being confined to respective domestic efforts of individual states. Lastly, we focus on the continuity of cooperative policies in the post-crisis period. This study examines the global financial crisis, environmental pollution, and COVID-19 as three illustrative cases – including both positive and negative instances – of crisis-driven regionalism, analysing why these crises have generated, or failed to generate, substantive cooperative outcomes.

Children associated with armed forces or armed groups (‘child soldiers’) experience conflict in highly differentiated ways, including in their exposure to gender-based violence. Cognisant of that reality, this article seeks to enrich current understandings of gender-based violence against female child soldiers by focussing on one relatively under-examined type: reproductive violence against female child soldiers. It revisits relevant cases from three jurisdictions which have most engaged with female child soldiers: the International Criminal Court, Special Court for Sierra Leone, and Colombian national courts. In each jurisdiction, the author closely examined publicly available court records, in order to detect references to (mostly uncharged) acts of reproductive violence against girls in armed groups. Forms of reproductive violence against child soldiers identified through this method include forcible impregnation and/or forced pregnancy, forced maternity, forced contraception and forced abortion, being forced to bear children before being sufficiently developed themselves, and the denial of reproductive health care. The article then explores how such reproductive violence might be charged as war crimes and crimes against humanity in future cases. This lens on child soldiers is especially timely, given the recent ‘reproductive violence’ turn in the field of international criminal law.

Predictions of the pedestal temperature profile calculated using a model for electron-temperature-gradient (ETG) turbulent electron heat transport Field et al. (2023 Philos. Trans. R. Soc. A, vol. 381, p. 20210228) are compared with the pedestal structure of H-mode plasmas in JET-Be/W (with Be wall and W divertor) over scans of the deuterium–tritium (D:T) isotope mix and hydrogenic gas fuelling rate Frassinetti et al. (2023 Nucl. Fusion, vol. 63, p. 112009). Predictions for the electron temperature at the location of the density pedestal top $T_e(\psi _N^{n_{e,top}})$ (where $\psi_N$, is the normalised poloidal flux) are found to agree well with measured values over both scans across the full range of D:T ratio. However, the pedestal top temperature $T_{e,ped}$, typically located somewhat inside the density pedestal top, is under-predicted by as much as a factor ${\sim} 2$. This implies that the ETG heat flux scaling appropriate for the steep-density gradient region, on which the model is based, is not applicable where the density gradient is weak. This difference might be attributed to a difference between the physics of the ETG turbulence in regimes where the density gradient is either strong or weak, which are thought to be dominated by either the ‘slab’ or ‘toroidal’ branches of ETG turbulence. Other branches of turbulence might also play a role in the electron heat transport, particularly in regions of weak-density gradient. As in the experiment, the predicted $T_e$ across the pedestal decreases with the ratio of separatrix to pedestal density $n_{e,sep}/n_{e,ped}$, which increases with the gas fuelling rate. Results from three models combining the ETG heat flux model with the EPED1 pedestal (EPED) model (Snyder et al., Phys. Plasmas, 2009, vol. 16, p. 056118) are also presented, including one which also incorporates the density pedestal prediction mode of Saarelma et al. (Nucl. Fusion, 2023, vol. 63, p. 052002), this model providing a complete prediction of the pedestal profiles.

Human genetic data are simultaneously deeply personal, familial, and strategically valuable, raising regulatory challenges that individual-centered privacy frameworks only partially address. This is highlighted by the recent high-profile bankruptcy filing by 23andMe, which triggered widespread public concerns extending beyond consumer privacy interests to potential national security risks. To address this, this paper proposes a three-layer diagnostic model for more comprehensive analysis of genetic data governance: (1) individual privacy as sensitive personal data; (2) relational and group (privacy) interests reflecting genetic data’s shared nature; and (3) the state or strategic layer treating genetic information as a national asset relevant to public health and security. Drawing on comparative examination of select jurisdictions and critical review of scholarship, this integrated framework offers researchers, policymakers, and private actors a practicable pathway to navigate the complex governance challenges posed by genetic data.

This article describes the nineteenth-century landscape of surface water distribution in cities of the U.S. West, focusing on its persistence after the advent of modern water mains, based on studies of San Antonio, Texas; Los Angeles, California; Salt Lake City, Utah; and Phoenix, Arizona. These systems of ditches, acequias, zanjas, and canals began as the primary urban water supply, then later comprised a secondary system complementing the mains. Ditch networks shrank in the twentieth century, but this ostensibly obsolete waterscape survived for decades and in many places to the present. Ditches persisted because they continued to serve the purposes of their users, because sanitary reforms abated their former pollution, and because new categories of utility emerged in amenity, heritage, and ecosystem services. The study takes the perspective of users as well as providers and finds, in contrast to conventional stories of hydraulic modernity, a continuing example of “water plurality.”
