This article examines anti-colonialism and Third World solidarities in Britain during the 1970s and 1980s. It does so through a study of the Black Liberation Front (BLF), a Black Power group formed in London in 1971. The BLF saw themselves as part of a global Third World solidarity, and, as activists in Britain, identified their location as ‘inside the belly of the monster’. They understood racism and colonialism as global phenomena, and offered material support to anti-colonial movements across the world, especially in Africa. The prevailing historiography of Black activism in post-war Britain foregrounds domestic anti-racism. Based on a reading of the BLF’s publications, alongside subsequent memoirs by and interviews with former BLF members, this article argues for Black activism in Britain to be viewed through a more global lens. Moreover, it shows how a deeper understanding of transnational anti-colonialism reconfigures our understanding of the domestic politics of race. Historians of decolonization must attend to how twentieth-century geographies of race and migration created the conditions for solidarities that do not fit within a metropole–colony binary.

The set of sums of two squares plays a significant role in number theory. We establish the existence of several rich monochromatic configurations in the natural numbers by exploiting algebraic structures induced by the set of sums of two squares. The proofs rely on algebraic properties arising from the induced structures on the Stone–Čech compactification of the natural numbers.

The widespread use of atrazine in corn since the 1960s has raised environmental concerns, such as ground and surface water contamination. The U.S. Environmental Protection Agency has proposed label restrictions on atrazine to address these concerns and requires applicators to achieve herbicide mitigation points before applying herbicides. One way to achieve mitigation points is to reduce the proportion of the field that is treated. Therefore, research was conducted in 2023 in Arkansas, Mississippi, Tennessee, North Carolina, Indiana, and Virginia, and in 2024 in Arkansas, Tennessee, and Indiana, to determine whether targeted applications can mitigate atrazine use in corn while maintaining weed control levels comparable to those achieved with broadcast applications. All plots, except the nontreated control, received paraquat and S-metolachlor immediately after planting in 2023, with amicarbazone and metribuzin added in 2024. Combinations of atrazine, glyphosate, and mesotrione were applied postemergence either broadcast, target-applied to emerged weeds, or a combination of broadcast and target-applied. Targeted applications of herbicides did not differ in weed control, including Palmer amaranth and morningglory species, compared to broadcast applications of the same active ingredients. No injury or differences in corn grain yield were observed. Targeted applications in 2023 covered 86% of the area, on average, while 52% of the area was sprayed on average in 2024. Differences in the area sprayed during the targeted application between years can be attributed to the reduced area of weed emergence from a more robust residual herbicide combination in 2024. Based on this research, targeted spray technology can reduce atrazine use in corn while providing weed control comparable to that achieved with broadcast applications.

We report an exceptionally early diagnosis of a Kommerell diverticulum on the first day of life, distinguished by unusual mid-ductal aneurysmal dilatation of the patent ductus arteriosus. Serial echocardiography documented the serial evolution of spontaneous ductal closure and thrombosis formation. CT confirmed a right aortic arch with a retroesophageal Kommerell diverticulum. The infant remains asymptomatic under close surveillance. This case represents one of the youngest reported cases with serial imaging documentation, providing unique insights into the early natural history and highlighting management challenges in asymptomatic neonatal patients.

This study examines whether behaviourally informed training can improve the effectiveness of phone-based tax debt collection in a public-sector setting. In collaboration with the Bulgarian National Revenue Agency, we implemented a two-day training programme for call centre agents focused on persuasion, negotiation and behavioural influence techniques derived from behavioural science and nudge theory. The impact of the intervention is assessed using descriptive comparisons of monthly aggregated debt-collection performance indicators before and after the training. We find that, following the intervention, trained agents achieved markedly better outcomes relative to pre-intervention periods, including an increase of approximately 20% in the total amount of debt collected over the subsequent three months and a higher rate of secured payment agreements. Notably, these improvements contrast with historical seasonal patterns that typically show a decline in collections during the same period. While the analysis is descriptive and does not permit definitive causal inference, the results provide strong indicative evidence that targeted behavioural training can enhance compliance outcomes in live, interpersonal interactions. The study contributes to the behavioural public policy and persuasion literatures by extending behavioural insights beyond written or digital nudges to real-time, conversational settings. From a practical perspective, the findings highlight the potential value of soft-skills and behavioural training for frontline public servants as a scalable and cost-effective tool for improving tax administration performance.

Authoritarian regimes have increasingly leveraged foreign media to project influence within democracies, yet evidence of these co-opted outlets’ actual effects remains scarce. This study presents findings from a field experiment conducted during Taiwan’s 2020 general election, assessing the impact of The China Times, a Beijing-backed media conglomerate, on voter behavior and attitudes. The experiment incentivized participants to engage in sustained consumption of real-time news from this outlet in the weeks leading up to the election. Results from a panel survey linked to individual-level web-tracking data reveal that exposure to The China Times sways voters in favor of the People’s Republic of China (PRC). These effects, however, are primarily driven by nonpartisan and PRC-friendly voters. To the extent that I find effects among PRC-skeptics, they show evidence of backfiring. As Beijing’s media co-optation extends beyond Taiwan, my findings have broader implications for understanding the effectiveness and limitations of authoritarian influence operations.

The influence of one of a bilingual’s languages on the other is known as cross-linguistic influence (CLI). In grammatical gender acquisition, CLI can occur during gender discovery, assignment and agreement. The present study investigates CLI in Dutch as a heritage language, a language with a non-transparent gender system, in two groups of bilingual children. One (i.e., Dutch-German bilingual children) is acquiring languages with similar gender systems and the other (i.e., Dutch-French bilingual children) is acquiring languages with more distant gender systems. We found CLI in gender discovery, gender assignment and gender agreement for the Dutch-German group but not for the Dutch-French group. Moreover, CLI simultaneously facilitated and hindered gender acquisition within the children, depending on the gender congruency of the nouns. This suggests co-activation of grammatical gender values in bilingual children. The findings help us better understand when cross-linguistic influence takes place and how it affects acquisition in bilingual children.

Dilute Temperley–Lieb algebras are variants of Temperley–Lieb algebras arising in statistical mechanics in the study of solvable lattice models. In this article, we prove that the (co)homology of dilute Temperley–Lieb algebras vanishes in all positive degrees.

Though critic Paul Scudo predicted in 1850 that the French romance would be ‘more respected by posterity than many weighty scores’, the once-ubiquitous song genre has all but disappeared from modern recitals and musicological histories. While the reasons for this erasure are undoubtedly multifaceted, I argue that the loss of the vocal performance practices that animated the genre played a significant role. Specifically, French singers in the domestic sphere – commonly labelled ‘romance singers’ and exemplified by figures like the tenor Richelmi – cultivated an entirely different vocal production than the one popularzied by Gilbert Duprez and typically heard in classical singing today. This technique, known as the timbre clair (clear timbre), was produced using a rising larynx and a lowering soft palate, resulting in a bright, thin, delicate, and even slightly nasal sound that became a hallmark of early and mid-nineteenth-century French singing. Moreover, composers and audiences expected singers to adopt a declamatory approach when performing romances, to constantly vary the colour of their voices for expressive effect. By so doing, performers imbued these seemingly simple songs with a sophistication and nuanced meaning not readily apparent in the scores themselves. This study of timbral aesthetics – which, I suggest, ought to be more seriously explored in modern performance contexts – undercuts conceptions of the genre as vacuous or meaningless and sheds light on an essential aspect of the nineteenth-century French sound world.

To date, there has been a long-term debate between the monetarists and Keynesian schools on the elements of inflation in countries, whether monetary or fiscal. Over the years, with the advent of the political economics and the governments’ active participations to the economic and social activities, a new factor, among others, in the name of good governance – say, controlling the corruption level – has arisen as the decider of inflation in countries. This study aims to examine empirically whether money supply, government expenditure (both capital and revenue) and corruption do maintain any long-run associations and short-run dynamics with inflation for the panel of the world’s 20 leading countries. The results reveal a long-run association between the fiscal, monetary, and governance variables, and inflation; and in the short run, there are causal influences from total government expenditure, money supply and corruption to inflation in developed countries, but capital and revenue expenditures, money supply and corruption cause inflation in developing countries.

The ethics of the international monetary system (IMS) can be framed either as a case of background injustice or of structural injustice. Both ideas suggest that due to the background conditions, the interaction of agents, in a context of no rules, can lead to domination and unfairness. Moreover, both ideas emphasise the need to create regulation, or a structure, that prevents domination and unfairness. This article asks how (if at all) do monetary regimes, or each of the three scenarios that stem from the Mundell-Fleming trilemma, raise domination and unfairness. This article identifies domination and unfairness in both regimes with open capital markets: the one with floating exchange rates and the one with fixed exchange rates. Moreover, it offers a principle of non-domination, according to which institutions of the IMS ought to guarantee effective sovereignty of participant states or offer an equal distribution of this value when securing full effective sovereignty for all is not possible. For the last regime, of closed capital markets, this article identifies unfairness but no domination. By identifying domination and unfairness in each regime, this article proposes policies and regulation, or a structure, to prevent and mitigate these issues.

Mental health literacy (MHL) strategies are crucial for mental health promotion and prevention. This study aimed to determine the acceptability, feasibility, appropriateness and initial efficacy of an adapted MHL program in a community sample of adults in Kenya. This was a quasi-experimental pre-post study conducted from July 2023 through July 2024. The MHL program contained nine modules delivered over 3 days. Participants were assessed at baseline and immediately after the program. The primary outcomes were mental health knowledge and participants’ attitudes on mental health/illness. Secondary outcomes included depressive symptoms, anxiety symptoms, self-perceived social support, self-perceived wellbeing, MHL program acceptability, feasibility and appropriateness. Relative to baseline, we observed statistically significant improvement in mental health knowledge and attitude on mental health/illness postintervention. We also observed significant improvements in all secondary outcomes. The MHL program also emerged as contextually appropriate, acceptable and feasible. The adapted MHL program is acceptable and appropriate and can feasibly be delivered by trained non-specialist facilitators. Also, the MHL program has the potential to increase participants’ MHL and attitudes and reduce symptoms of common mental disorders and promote self-perceived wellbeing. Future research should explore how improvements can be sustained over the long term.
