We study the space of traces associated with arbitrary full free products of unital, separable $C^*$-algebras. We show that, unless certain basic obstructions (which we fully characterize) occur, the space of traces always results in the same object: the Poulsen simplex, that is, the unique infinite-dimensional metrizable Choquet simplex whose extreme points are dense. Moreover, we show that whenever such a trace space is the Poulsen simplex, the extreme points are dense in the Wasserstein topology. Concretely for the case of groups, we find that, unless the trivial character is isolated in the space of characters, the space of traces of any free product of non-trivial countable groups is the Poulsen simplex. Our main technical contribution is a new perturbation result for pairs of von Neumann subalgebras $(M_{1},M_{2})$ of a tracial von Neumann algebra M, providing necessary conditions under which $M_{1}$ and a small unitary perturbation of $M_{2}$ generate a II$_{1}$ factor.

This study evaluated the effect of sweet whey fermented by Lactobacillus delbrueckii subsp. bulgaricus NCFB 2772, an exopolysaccharide (EPS)-producing lactic acid bacterium (LAB), on the yield and quality of Requeson, a traditional Mexican fresh cheese, further supplemented with the probiotic strain Lactobacillus casei 431. Fermentation of the whey at 42°C for 48 hours resulted in the production of 1.126 ± 0.12 mgeq dextran/mL of EPS. The incorporation of this EPS-rich whey led to a marked (∼230%) increase in cheese yield and significantly enhanced textural properties, including greater hardness, cohesiveness and elasticity. Furthermore, L. casei 431 maintained viability above 107 cfu/g throughout 21 days of refrigerated storage (4°C), with no detectable microbial contamination. Although formulations containing EPS were slightly preferred in sensory evaluations, they exhibited improved stability and retained overall acceptable sensory quality. These results highlight the potential of EPS-producing LAB and probiotics to improve the technological, nutritional and functional attributes of fresh cheese, while contributing to the valorisation of dairy by-products.

It is widely assumed that English law adopts a restrictive approach towards tort actions for “wrongful life”. This article reveals the true legal position to be much more complex. A broad distinction exists between cases where the wrong occurred before or at conception and those where it occurred during pregnancy, with claims usually being permitted in the former scenario but not in the latter. In this article, I expose this bifurcation as arbitrary before examining potential solutions for remedying it.

Key to the success of international peace-building efforts is the cooperation and support of civilian populations. Studies show that economic considerations shape combatants’ willingness to lay down their arms. We study a related but under-studied question: does economic hardship impact civilian support for conflict cessation? If reintegration of former combatants into productive economic sectors threatens civilians’ own incomes, then support for peace-building may diminish. We investigate localized effects of the 2015 Hindu Kush earthquake using individual-level survey data on support for Taliban reintegration. The earthquake reduced support for reintegration into disproportionately impacted economic sectors. We observe no effect for less impacted sectors. Results are robust to a battery of tests, including a novel spatial randomization leveraging geocoded fault lines corresponding to the universe of counterfactual earthquakes. Our findings provide new insight into the resolution of violent conflict: economic hardship may undermine civilian support for rebel reintegration.

This paper examines what Seneca, Controuersiae 9.2 can contribute to understanding of the maiestas laws under Augustus and Tiberius. In this period, two distinct judicial spaces are known to have hosted cases tried under these laws: the traditional Republican standing court and the new senatorial court, which supplanted its predecessor at the latest from the years immediately following the accession of Tiberius. Yet in the same period a third judicial space acquired new prominence: the schoolrooms of the declaimers, in which teachers of rhetoric, their pupils and sundry adult performers gathered to participate in the fictional trial fοr maiestas laesa of L. Quinctius Flamininus. Moving between these spaces and considering the interrelationship of the different statutes that they employed, this paper shows how the superficially escapist practice of trying Flamininus could also offer a vehicle for reflection on the drastic legal and political changes taking place in the world outside. Building on close analysis of the contribution of Votienus Montanus, the paper seeks to reconstruct key provisions of the hypothetical late Augustan lex Iulia maiestatis. It finally details how many of those quoted in the exercise risked or actually underwent prosecution for maiestas or themselves launched such prosecutions.

The preservation of vernacular architecture in Təgray, Ethiopia, faces significant challenges due to factors such as conflict, ‘modernization’, socio-economic pressures, and environmental degradation. These issues have accelerated the transformation of this architectural heritage landscape, underscoring the need for innovative conservation strategies. This field study, conducted between January and August 2024, combines archival research with advanced 3D documentation technologies to propose a preservation framework. It highlights the limited access to archives from previous studies and expeditions, which are often stored in European and North American institutions. While increased digitization has improved this situation, it still hinders local scholars, authorities, and communities from effectively contributing to science-based conservation efforts in the region. Greater access to these archives would significantly benefit the growing movement of community-driven conservation activities. By integrating archival data with 3D documentation techniques, a comprehensive understanding of vernacular architecture can be achieved, encompassing its historical development and enabling the formulation of effective preservation strategies. This approach allows for detailed insights into construction methods, spatial organization, and the cultural significance of buildings, enhancing conservation efforts and ensuring the preservation of architectural heritage for future generations. The research demonstrates that sustained access to archival information, combined with advanced 3D technologies, significantly enhances the accuracy of documentation, spatial analysis, and restoration planning for Təgray’s architectural heritage. Moreover, these advanced documentation technologies function as dynamic archives, refining the precision of earlier architectural records and facilitating more effective community outreach and application. The study also underscores the importance of collaboration among heritage professionals, archivists, technology developers, and local communities to ensure sustainable and comprehensive preservation initiatives.

Recent commentaries on Iran have stressed attacks on workers and wages by a neoliberal regime bent on slashing costs in response to sanctions, stagnation, and inflation. At the same time, Iranian political elites and government experts uniformly advocate for higher minimum pay. Underneath this paradox lies a complex shift of class inequality away from salary scales determined by firms and government agencies toward a single minimum wage set every year by the Supreme Labor Council, the central body responsible for employment policy. The result is not labor discipline or wage repression but an unruly wage containment state. Integrating archival sources, interviews, and statistical data, the article examines how elite conflicts, societal interests, and economic forces have structured the politics of pay in Iran. Framed comparatively, Iran’s wage containment state is a product of the way in which politics, development, and international relations have shaped Iranian capitalism.

Ireland’s historical coordinates are shifting, prompting a re-examination of national narratives and of the assumptions and anxieties that have kept them in place. Increasingly, stories that disturb rather than coalesce with grand narratives are the focus of historical study, revealing the structural violence used to maintain societal order. This article argues that tending to bigger questions about power and smaller ones about human experience creates space for new and diverse histories. It explores the dynamics that shaped the grand narratives central to Irish history and proposes the idea of imagined and lived encounters as a way of thinking about differentiation, the relational nature of power and its impact on experience and everyday life. An analysis of the concept of respectability is used to probe how power functions. The article concludes with a consideration of the historical archive broadly defined, highlighting the benefits of embracing the ‘unreliable’ witness, listening and accounting for silences, touching the material, and considering imagination as a force constantly at play in the encounters that shape history. The acceptance of this dynamic instability in historical research creates possibilities for new voices and perspectives to emerge.

The integration of Generative Artificial Intelligence (GAI) is reshaping traditional legal pedagogy by introducing new dimensions to research, drafting, and personalized learning. Despite its transformative potential, the application of GAI in legal education remains promising and is accompanied by such challenges as algorithmic bias, privacy concerns, and the generation of fabricated or inaccurate content—issues that continue to divide scholarly opinion on its adoption. With this in mind, the University of Kansas School of Law offered a one-credit, one-hour course on “AI for Lawyers” during the summer of 2025. Along with reproducing the syllabus of the course and some of the professor’s observations, the paper includes an overview of AI and legal pedagogy and some recommendations going forward for integrating AI into law school curricula.

The proliferation of fortification in north-western Europe during Late Antiquity marks an important shift from the first to early third centuries. The fortified cities and military installations were joined by new fortified towns and rural and hilltop defences. While these defences have been extensively studied, there has been little engagement with this transformation at a statistical level. This article provides an overview of defence in the region using data collected across northeastern Gaul and the provinces of Germania Secunda and Germania Prima. It will highlight biases, distributions and key variations in the dataset and demonstrate regional variations in defence on a large scale.

The Ketton Mosaic depicts the duel between Achilles and Hector, the dragging of Hector’s body and its ransom. Despite initial associations with the Iliad in the press, this article demonstrates that the Ketton mosaic does not illustrate scenes from Homer but an alternative variant of the narrative which originated with Aeschylus and remained popular in Late Antiquity. The composition also reveals its debt to a pattern repertoire shared by artists working in media such as painted pottery, coin dies and silverware, which had been circulating in the ancient Mediterranean for many centuries. Through its textual and visual allusions, the Ketton mosaic makes a strong case for the engagement of fourth-century Roman Britain with the cultural currency of the wider empire.

Dairy cow longevity affects production economy, climate footprint, and cow welfare. Based on data from the Danish Cattle Database, this research paper evaluates the relationship between early-life risk factors associated with the period before first calving and cow longevity, including data from all Danish dairy cows culled in 2019–2023. Explanatory variables for linear mixed models included calf size, twinning, and age at first calving. Information about the length of productive life (LPL) (mean: 1,074 days) and lifetime milk yield (mean: 32,088 kg energy-corrected milk) was available for 767,305 and 716,120 cows, respectively. Milk yield per day of life increased from 7 kg in cows culled during the first lactation to more than 20 kg in cows culled in their fifth or later lactations. For cows born as singletons, LPL was one month longer for cows born as large calves than for medium-sized calves, and 2 months longer than for small calves. Cows born as twins had 2 to 3 months shorter productive lives compared to cows born as singletons. For singletons, lifetime milk yield was 1,200 kg higher for large calves than for medium-sized calves, and 2,100 kg higher than for small calves. Lifetime milk yield was 1,500 to 3,500 kg lower in cows born as twins. Cows being among the third quartile of age at first calving had an estimated productive life 2.5 months longer, and a lifetime milk yield more than 2,600 kg higher than cows calving among the first quartile of age. The results from this study clearly demonstrate the importance of ‘a good start’.

In this article I endorse the contention that humour presents a window onto the complicated social relationships and consciousness of speakers and listeners. Drawing on long-term ethnographic research in Bushbuckridge, South Africa, I observe that improvised joking and the telling of standard jokes have proliferated over the past three decades. I suggest that we can understand both forms of humour as bids to construct intimate interpersonal relations, based on mutuality, in times of increased precarity. There are, nonetheless, important differences between these forms of humour. In Bushbuckridge, a long tradition of spontaneous and improvised joking between certain categories of persons stood at the very heart of kinship. The association of such joking with intimacy was evident in the general rule that one was only allowed to joke, particularly about sexual matters, with persons one was allowed to see naked. By engaging in such joking, villagers reinforced mutuality with kin, upon whom they relied for social security. By contrast, the (re)telling of standard jokes is a fairly recent practice. Unlike in joking between kin, the original composers of the jokes are anonymous and the butt of the jokes are fictitious third persons. This insulates listeners from direct embarrassment and the teller from retaliation. These jokes were told between male peers, and commented on the diminished status of men in contemporary times. By telling standard jokes, men provoked ‘laugher out of place’, in a bid to re-establish sociality in moments of distress and extend mutuality beyond the domains of kinship networks.

The notion of ‘concrete Sape’ constitutes the central heuristic tool of this study. Inspired by the Congolese elegant art of dressing (La Sape) – a form of ostentatious elegance in contexts of precarity – it refers here to strategies of urban display and the simulation of state order through spectacular constructions in contexts marked by war or post-crisis. Much like the body of the sapeur, which masks social fragility under the guise of appearance, the concrete-clad city showcases an image of an urban modernity that hides inequalities, political instability and the structural weaknesses of the state. This metaphor enables a joint analysis of the logics of simulacra, extraversion, violence and legitimation at play in the political economy of concrete. This study is rooted in a comparative ethnography of the post-crisis real-estate boom observed in Kinshasa and Brazzaville since the 2010s. It combines direct observations, a photographic corpus of public and private buildings, participation in real-estate fairs, and over thirty semi-structured interviews and informal conversations. By bridging urban studies and the socio-anthropology of politics, it sheds light on the mechanisms of simulacra, violence and political legitimation embedded in the economy of concrete and construction in Central Africa, both within and beyond post-conflict contexts.
