Two research branches in evolutionary psychology can make similar predictions about treatment expectations in contexts of conflict of interest, where, for those involved, costs and benefits are at stake. Recalibrational Theory of Anger suggests that evolved psychological mechanisms operate at the cognitive level and regulate human behavior. The Dark Triad Personality posits that traits of Machiavellianism, Narcissism, and Psychopathy confer adaptive advantages, leading individuals to prioritize their interests over those of others. This study aimed to replicate the results of Sell et al. (2017) in a Brazilian sample (Replication Analysis) and investigated whether dark triad traits predict the magnitude of anger in conflict-of-interest situations (Extension Analysis). Replication Analysis consistently replicated previous findings, with effect sizes from moderate to large magnitudes. Extension Analysis revealed that only Narcissism was a significant predictor when victims were intentionally targeted by offenders. While the Recalibrational Theory of Anger predictions were largely confirmed, the dark triad personality traits, except for Narcissism, were generally poor predictors of anger magnitude. The results suggest that the universality of the information processing is robust and is little influenced by antisocial personality characteristics.

This introduction presents a novel framework that distinguishes three activities of organized crime (OC): production (creating goods and services), trade (moving products and people), and governance (regulating markets and controlling communities). These activities require different skills and give rise to three different types of OC groups. To illustrate some of the points, I make references to the papers published in this Special Issue, on erotic fiction in China by Wang and Evelyn; on falsified medicines production and trade between Asia and Europe by Hamill; on drugs retail and gang control of a neighbourhood in Marseilles by Rodgers and Jensen; and the cocaine international distribution chain by Feltran.

In the Roman imperial worldview, masculine, civilized Rome saw a duty to control and care for uncivilized, feminine foreigners—a gendered power dynamic shared by more recent colonizing states as well. However, it is a methodological challenge to catch sight of the way such a worldview may have impacted colonial subjects. I examine the impact in Roman Britain and Gaul by applying a symbolic anthropological approach to a well-suited body of evidence, votive offerings: widely accessible and highly individual, each represents a single symbolic act. Taking up archaeological questions of material symbolism, I analyse the confluence of gender and offering material categories. Analysis of objects men and women offered at 10 sanctuaries in Britain and Gaul, and of the materials in which men and women were portrayed, reveals a permeability–impermeability binary: women are associated with breakable clay, porous bone and translucent glass, and men with strong, durable metal. This binary reflects Roman understandings of femininity and masculinity, shedding light on the fraught relationship between colonial rule and gendered understandings of the world.

This introductory article situates the study of gratitude within the historiography on emotions and transatlantic relations, particularly in relation to the affective turn in the humanities and social sciences. It also sets out the common goals of the articles: inviting historians to take gratitude seriously by defining its relationship to ongoing work in memory, humanitarian and international studies. By identifying a diplomacy of gratitude, it centres on emotional practices and performances and illustrates how this draws in new actors, behaviours and processes to our overall understanding of European–United States relations. Finally, it argues how the contributions to this special issue collectively reveal the historical development of repertoires and processes of gratitude throughout the ‘Transatlantic Century’.1

This study concerns how the Online Coins of the Roman Empire (OCRE) database of imperial coins can support Year 12 students to learn about Roman imperial image on coins for their Classical Civilisation Imperial Image paper. In observations of lessons, the author noted that pupils struggled to remember and identify coins which were prescribed sources for their examinations and appeared disengaged in other teaching methods. The author taught pupils how to use the OCRE database. When using the database, all pupils seemed more interested and engaged in the study of coins. Indeed, pupils’ classwork and written essays showed that, after using the database, their use of coin-related terminology and metalanguage increased, they wrote more detailed descriptions of coins, and considered how coins contributed to Augustus’ imperial image. The author recommends that teachers allow an extended period for students to become familiar with the software before formal activities. He suggests engaging activities for students such as finding and presenting coins to the class, curating displays of coins, or finding coins depicting various animals in the quickest time. Teachers could vary the time on each activity depending on the lesson time available.

This article suggests that the economically activist tendencies of the European Union are not just a temporary response to exogenous crises, but part of a long-term transformation of the EU into a governance structure that is increasingly equipped for forms of more direct rule over its territory, economy, and citizens, albeit still in an incomplete and contested manner. This transformation hinges on three interlocking processes that feed into each other and accelerate: (i) the rise of EU-level material, financial, and institutional infrastructure; (ii) the significant centralisation of EU power; and (iii) novel narrations about the ‘point’ of the EU that stabilise its authority. This transformation of the EU brings with it new challenges for its authority. Using the work by Charles Tilly, who focuses on the way in which trust networks are integrated in rule, this article distinguishes between the EU’s ability to rule by way of coercion, by way of capital and by way of commitment. It is suggested that while the EU’s ability to rule by way of coercion and capital have grown, it remains difficult to envisage how the EU may stably reproduce commitments structures that would allow it to transition into a stable and democratic structure of governance.

Avian schistosomatids are blood flukes parasitizing a wide spectrum of aquatic birds. However, its research in the Neotropics is ongoing with several putative new taxa pending description. Although waterfowl represent the most important avian hosts for these flukes, only a small proportion of these birds have been assessed for schistosomatids. This study aimed to describe avian schistosomatids from two native ducks from the Southern Cone of South America. A total of 24 Chiloe wigeon (Mareca sibilatrix) and three Cinnamon teals (Spatula cyanoptera) from different localities in Chile and Argentina were dissected to retrieve schistosomatids. The retrieved worms were described through an integrative approach considering morphology (staining and SEM) and molecular tools (PCR: COI, 28S rRNA genes). The new schistosomatid: Trichobilharzia kulfu sp. nov. was recovered from the viscera of Chiloe wigeon. It was closely related to other undescribed Trichobilharzia taxa from the United States, also from Mareca ducks. The new species was morphologically and molecularly different from other Trichobilharzia species, and it was included in the clade Q. In addition, SEM imaging proved to be an important tool to describe unnoticed traits on the tegument of worms. This new species represents the second Trichobilharzia taxon from the Neotropics described through an integrative approach. Furthermore, the Cinnamon teals harboured Trichobilharzia querquedulae. Considering there are several avian schistosomatids described only through morphological or molecular tools, there is a clear need to include a comprehensive approach in the description of avian schistosomatids, considering the remarkable richness of schistosomatids in Neotropics.

Democracy faces growing threats from authoritarian ideologies, especially in terrorism-affected regions. We test whether citizen-targeted democracy-promotion intervention can bolster democratic support and resist authoritarian appeals. A randomized online experiment in Burkina Faso exposed participants to educational videos focusing on: (1) introduction of civic rights democracies offer, (2) general discussion of democracy’s advantages in combating terrorism, (3) Burkina Faso–specific discussion of democracy’s advantages in combating terrorism, (4) space exploration (placebo). Democracy-promotion videos increased democratic support. The general terrorism-advantage message produced the largest gains, whereas the country-specific message had little effect. Effects are not contingent on respondents’ proximity to attacks or direct experience. These findings highlight how democratic resilience can be strengthened in conflict-affected societies and inform future efforts to promote democracy.

This reflective essay responds to current redundancies in the sector of Classics teaching. tristia ex Dorcestria recounts the author’s near-miss experience of redundancy and considers the place of Classical subjects in the twenty-first-century curriculum. Written from the intersectional perspective of a Classics teacher, researcher and poet, the piece discusses the composition of the award-winning poem Manifesto, recipient of the Classical Association’s 2025 Write–Speak–Design Prize, and explores how creative practice became a means of transforming professional loss into pedagogical insight. Drawing on the metaphor of Ovidian exile, the essay situates one teacher’s story within a broader context of national uncertainty about the value and future of Classics. The essay demonstrates that creative practice can function both as personal catharsis and as a mode of critical reflection, enabling educators to reimagine their role and reconnect with the emotional and ethical dimensions of ancient study. The accompanying poem models how teachers might use creative responses to engage students with questions of power, justice, and identity, and to affirm the continuing relevance of the ancient world in addressing modern crises, not least those relating to war and violence, marginalisation, and democracy.

The bulk organic-matter content of near-surface sediment is widely used for radiocarbon (14C) dating, despite often containing organic carbon (OC) older than the depositional age. Low-temperature combustion can mitigate the influence of old OC, producing ages closer to the depositional age. We developed a simple method to determine the 14C age of the low-temperature (<250°C) component of bulk sediment. Sediment samples from five Arctic lakes were heated up to 400°C, revealing that at 250°C, about half of the OC combusts, leaving behind the more recalcitrant fraction. We applied this method to 64 samples from late glacial and Holocene sediment cores, analyzing 14C and % OC in two aliquots: one heated at 250°C and one unheated. The low-temperature 14C age was calculated by difference using a two-component mixing model. Accuracy was assessed by comparing ages with macrofossils from 48 samples, and reproducibility was tested using a standard reference material. Results show that low-temperature combustion yields 14C ages with an interquartile range of 115 years, and with reproducibility on par with that of macrofossil dating. On average, the ages differ by 932 years from macrofossils, compared to a 2425-year difference for conventional bulk-sediment ages analyzed in this study. Accuracy improves for samples where the proportion of residual OC after heating is low. This practical and efficient method complements macrofossil dating, supports analysis of a large number of samples, and provides insights into sedimentary carbon cycling.

In these replies, I respond to critical comments on my book (Radical Skepticism and Epistemic Intuition, Oxford 2021) from Julia Smith, Louis Doulas, Bill Lycan, and Matthias Steup, who (along with me) contributed to a symposium on that book for this journal. I discuss the following topics (among others), all in the context of my commonsense response to radical skepticism: epistemic intuitions, evidence, disagreement, philosophical pessimism, epistemic modesty, inference to the best explanation, theoretical virtues, particularism, methodism, epistemic circularity, and higher-level requirements on epistemic justification.

Asymptotic giant branch (AGB) stars are important to chemical evolution at metallicity $Z \sim 0.0001$ ($\text{[Fe/H]} \approx -2.2$) as they contribute significantly to the production of nitrogen, lead, and dust in the early Universe. The contribution of AGB stars to the chemical evolution of the Universe is often quantified using the chemical yields from single AGB stars. Binary evolution challenges our understanding of chemical evolution as binary phenomena such as mergers and mass transfer episodes can significantly alter the stellar evolution pathways and yields. In this work, we use binary population synthesis code binary_c to model populations of low and intermediate-mass ($\sim 0.7$–$7\,\mathrm{M}_{\odot}$) stars at metallicity $Z = 0.0001$. Our binary star populations predict $\sim 37\%$ fewer thermally pulsing AGB stars than our single star populations, leading to a $\sim 40\%$ decrease in the amount of ejected C and a $\sim 35$–40% reduction in elements synthesised through the slow neutron capture process. The uncertainty introduced by the mass-loss from stellar winds on the AGB makes the impact of binary evolution on the total amount of ejected N uncertain. The total N yield ejected by our binary star populations ranges from a 17% to a 36% decrease compared to our single star populations. However, our binary populations overproduce N by over an order of magnitude during the period $300\text{--}700\, {\rm Myr}$ after formation.

Antiquities in the Middle East region face various threats, including illicit trade, theft, and forgery. This research examines a leather manuscript obtained by the Palestinian Tourist Police following the arrest of an antiquities smuggler. The manuscript contains Phoenician inscriptions along with symbols such as the Menorah, Shofar, and a plant branch. Radiocarbon dating using accelerator mass spectrometry (AMS) techniques determined the manuscript’s date to be post-1950 CE. Therefore, the results indicate that the manuscript is a modern forgery, likely created for commercial purposes. Additionally, the text contains several grammatical errors, further supporting the conclusion that it is not an authentic historical artifact.
