This article examines Rokeya Hossain's “Sultana's Dream” (1905), a short story that pictures a solar-powered utopia governed by women, as a key site for thinking through the entanglements of sovereignty, gender, colonization, and environmental relations as they are articulated through infrastructure. To read infrastructurally in this way, we attend to socio-historical contexts of nineteenth-century Bengali society and to the Victorian imperial roots of early solar inventions, alongside the more modular aesthetics and meaning-making affordances of solar energy. Such a mode of reading makes infrastructure legible as an essential political ground for the maintenance or transformation of socio-ecological relations and reveals the irreducible political, material, and poetic qualities of infrastructures themselves. Texts like “Sultana's Dream” make such configurations visible and open to interrogation, and demonstrate the ways that solar, as infrastructure, energizes new social and political forms—even those yet undreamed.

We present the Sydney Radio Star Catalogue, a new catalogue of stars detected at megahertz to gigahertz radio frequencies. It consists of 839 unique stars with 3 405 radio detections, more than doubling the previously known number of radio stars. We have included stars from large area searches for radio stars found using circular polarisation searches, cross-matching, variability searches, and proper motion searches as well as presenting hundreds of newly detected stars from our search of Australian SKA Pathfinder observations. The focus of this first version of the catalogue is on objects detected in surveys using SKA precursor and pathfinder instruments; however, we will expand this scope in future versions. The 839 objects in the Sydney Radio Star Catalogue are distributed across the whole sky and range from ultracool dwarfs to Wolf-Rayet stars. We demonstrate that the radio luminosities of cool dwarfs are lower than the radio luminosities of more evolved sub-giant and giant stars. We use X-ray detections of 530 radio stars by the eROSITA soft X-ray instrument onboard the Spectrum Roentgen Gamma spacecraft to show that almost all of the radio stars in the catalogue are over-luminous in the radio, indicating that the majority of stars at these radio frequencies are coherent radio emitters. The Sydney Radio Star Catalogue can be found in Vizier or at https://radiostars.org.

This review looks back on our experience with acute middle cerebral artery embolectomies in the 1990s, frowned upon by stroke experts at the time, and no match for the newly introduced and proven treatment of acute ischemic stroke with intravenous recombinant tissue plasminogen activator (alteplase). The past several decades have seen dramatic developments in acute cerebral revascularization, the major paradigm shift being in the form of endovascular thrombectomy. Mechanical thrombectomy has moved from the operating room, where we performed it, to the interventional angiography suite armed with ever-improving clot aspiration and retrieval technologies.

Pensions were a means of social provisioning long before they became a cornerstone of state welfare policies in the early twentieth century. The multifarious pension forms that persisted and were reshaped during the Victorian period offer occasions to glimpse how social bonds and obligations across time were imagined and contested. The pensions of Charles Dickens's Bleak House (1852–53) suggest how the infrastructural potential of a form might flicker within the literary text, even as it is unacknowledged and left behind.

People are often assumed to expand existing mechanisms—kinship in particular—to include others when they form communities. These models (con)fuse similarity with sameness, as we argue based on Husserl's concept of empathy. People recognize others without overlooking differences. They form community by negotiating belonging. We ask how individuals materialize community, how they create unity in a political process, and how they employ bordering and bonding social interactions. Our case study is Dos Ceibas, a Late Preclassic (350 b.c. to a.d. 250) Maya hamlet in the Petexbatun region. The North Plaza originated as a residential group—possibly of the hamlet's founder—and was transformed over multiple construction episodes into a public and ceremonial place. By a.d. 250, Dos Ceibas consisted of a small pyramid overlooking a plaza and two likely residential buildings. Its growth pattern sets the North Plaza apart from nearby Group MP16 and magnified internal differences. At the same time, Dos Ceibas's pyramid and plaza were likely communal constructions that project a shared community identity. The comparison with contemporary settlements nearby identifies distinct settlement layouts and suggests localized community identities.

In many countries, the economics domain forms a routine part of health technology assessments (HTA) next to analyzing the comparative effectiveness and safety of a technology. The method applied most often is economic evaluation, such as cost-effectiveness analysis, which is supposed to support the efficient use of resources. In Austria, economic evaluation has played a negligible role in HTA and reimbursement decisions, even though the country faces the same public healthcare sustainability challenges as others. In this commentary, we argue that while health economics will need to play a more active role in HTA-related decision support to deal with those challenges, current approaches in other countries may have to be broadened to fit the Austrian context. We are outlining four arguments to underpin this perspective: First, economic evaluations (in their current form) are of limited benefit for supporting reimbursement decisions of new high-priced technologies. Second, a broader variety of health economic methods is needed to address the scope of technologies. Third, applying health economic methods requires a reflection on their underlying values. Finally, health economics within HTA needs to go beyond microeconomic analysis of interventions. We are suggesting several alternative methods and approaches, encouraging out-of-the-box thinking and experimenting with methods developed in the academic context but rarely applied in routine HTA. Although some of our topics are unique to Austria, others may equally apply to other healthcare systems. With our thoughts, we aim to stimulate discussions for further developing health economics within HTA in Austria and internationally.

Business actors play increasingly important roles in global governance and international regulation. This paper considers how regime complexity influences the roles of businesses and impacts opportunities for business influence on international regulatory regimes. We conducted a scoping literature review of 243 articles from the International Regime Complexity (IRC) theory literature to explore if and how complexity affects the roles of businesses and their influence on international regulation. We found that complexity presents opportunities for businesses to regime shift and exploit knowledge asymmetry in order to influence international regulation. Further, IRC theory illustrates how the roles of businesses interact and leverage one another in order to create better opportunities for influence in specific international regulatory regimes. This paper contributes to IRC theory by building on the existing non-state actor discussions and offering specific theorization of business behavior, thus starting to bridge the gap between the empirical and theoretical understanding. Second, it contributes to existing discussions in business and politics literature by developing existing knowledge on the roles of businesses in global governance to better reflect the added dimension of complexity.

Synthetic controls (SCs) are widely used to estimate the causal effect of a treatment. However, they do not account for the different speeds at which units respond to changes. Reactions may be inelastic or “sticky” and thus slower due to varying regulatory, institutional, or political environments. We show that these different reaction speeds can lead to biased estimates of causal effects. We therefore introduce a dynamic SC approach that accommodates varying speeds in time series, resulting in improved SC estimates. We apply our method to re-estimate the effects of terrorism on income (Abadie and Gardeazabal [2003, American Economic Review 93, 113–132]), tobacco laws on consumption (Abadie, Diamond, and Hainmueller [2010, Journal of the American Statistical Association 105, 493–505]), and German reunification on GDP (Abadie, Diamond, and Hainmueller [2015, American Journal of Political Science 59, 495–510]). We also assess the method’s performance using Monte Carlo simulations. We find that it reduces errors in the estimates of true treatment effects by up to 70% compared to traditional SCs, improving our ability to make robust inferences. An open-source R package, dsc, is made available for easy implementation.

Despite crowdfunding platforms’ growing involvement in financing welfare, related ethical issues have received little scholarly attention. To address this gap, we focus on GoFundMe, the leading welfare crowdfunding platform in the US, to examine whether it facilitates the establishment of a just society that democratizes access to funding. Informed by Rawls’s ethics, we conduct a comprehensive analysis, arguing that GoFundMe’s modus operandi merits criticism. We advance three interrelated arguments for why GoFundMe is morally problematic. First, it distributes information and primary goods unfairly, perpetuating inequalities that disadvantage the most vulnerable. Second, it uses narratives that may distract public attention from systemic flaws in welfare provision, potentially reducing social pressure for institutional reform. Third, its emphasis on individual choice and responsibility may contribute to momentum for neoliberal policymaking. We show why scholars, policymakers, and platforms should engage in debate about regulating welfare crowdfunding activities to improve their ethicality.

The emotional valence hypothesis suggests an increased left-brain hemisphere activation during positive situations and vice versa during negative situations. Since facial thermal asymmetries may reflect lateralised brain activity, we investigated this in dairy calves subjected to hot-iron disbudding (Disbudded; n = 12) as a model of negative affective states. As affective responses can vary due to previous experiences, we examined whether calves that had (ExpObs; n = 12) and had not (InexObs; n = 12) experienced disbudding differed in their thermal response to a conspecific being disbudded, and whether calf response to the researcher (approaching, moving away, not moving) was associated with thermal asymmetries. We made thermographic recordings of each calf on three days: Day before disbudding (D1); Disbudding day (D2); and Day after disbudding (D3), and at two different times: Disbudding time/1400(T1) and Afternoon/1700(T2). Data were analysed using multilevel models. Calves had warmer left ears on D2 compared to higher temperatures on the right ear on D1, suggesting higher right-hemisphere activity on D2. ExpObs calves had higher left-eye temperatures when observing a conspecific being disbudded (D2×T1) than InexObs calves that had warmer right eyes, but this reversed on the following day (D3×T1). Calves avoiding the researcher had warmer left eyes whereas those approaching him had warmer right eyes, suggesting greater activation of the right hemisphere in the former. This study provides initial evidence of temperature asymmetries when observing or experiencing a negative event. Further work is required to confirm and build upon these early findings. The study highlights the potential for future development of methods using infrared thermography as a proxy measure of affective valence.

This paper examines the dependence structure and risk spillovers between oil prices and exchange rates in both oil-exporting and oil-importing countries. Using a flexible dependence switching copula model, we analyze both positive and negative dependence and transitions between the dependence regimes. Additionally, we investigate the directional risk spillovers between oil and currency markets in both their downsides and upsides. Based on empirical data from 1999 to 2024 for major oil-exporting and oil-importing countries, we find that oil price-currency dependence is predominantly positive for oil-exporting countries, with infrequent transitions, but mainly negative for oil-importing countries, with frequent transitions between the two dependence regimes. These transitions often occur around crisis or war times. Furthermore, we observe that during downturns in the oil market, tail dependence between oil prices and currencies becomes more pronounced than during upturns. Our results indicate the presence of risk spillovers between oil and currency markets, with the downside spillover effects outweighing the upside ones. Moreover, we find that risk spillover is stronger from oil markets to currency markets than the reverse direction. These insights substantially enrich the existing literature and would offer valuable implications for effective risk management strategies and policymaking.

As part of the effort to secure the release of the Dorchester Labourers, a group of agricultural workers sentenced in 1834 to penal transportation, London theaters hosted four fundraising evenings for the prisoners and their families. A turning point in the popular stage, these evenings marked a moment when commercial venues became willing to ally with working-class protest movements. At three of the four events, the theaters mounted nautical melodramas. Using Judith Butler's theories of the political possibilities of mourning, this article argues that melodrama effectively explored the twinned crises of social austerity and political repression while imagining radical transformation emerging from loss.

In this article I issue a challenge to what I call the Independence Thesis of Theory Assessment (ITTA). According to ITTA, the evidence for (or against) a theory must be assessed independently from the theory explaining the evidence. I argue that ITTA is undermined by cases of evidential uncertainty, in which scientists have been guided by the explanatory power of their theories in the assessment of the evidence. Instead, I argue, these cases speak in favor of a model of theory assessment in which explanatory power may indeed contribute to the stabilization of the evidential basis.

The paper analyzes family-level wealth inequality and social mobility in Dudelange (Luxembourg) over five generations between 1766 and 1872, a period that saw the end of feudal social relations. While the integration of Luxembourg into the French revolutionary regime produced a reduction in the Gini coefficient for the ownership of land, the social mobility analysis reveals a relative stability of family positions within the land-wealth distribution throughout the period. This shows that family-level transmission mechanisms limit social mobility and strongly advantage those with ancestors owning property wealth, even when there are significant changes in the organization of property relations.
