The period of struggle over hydrocarbon sovereignty in the Arab world –the 1950s-1970s– saw a spate of periodicals in Arabic about oil. These included periodicals produced by the public relations departments of Euro-American oil companies, as well as monthlies, weeklies and quarterlies produced by Arab journalists, experts, and former oil revolutionaries in Cairo, Baghdad, Beirut and Kuwait. This essay argues that the trajectory of these latter publications –both their context and content– traces the massive political transformations that saw a shift of power in the region, alongside a radical transformation in the representation of oil from a public good into a private property.

This article contributes to broader discussions of early Latin American nation-making by focusing on the interplay among territory, sovereignty and human movement in nineteenth-century Central America. How did early Central American nations create sovereign spaces? And how did human movement in turn impact the meanings of bordered spaces? Drawing from constitutions, legal codes and archival documents related to the implementation of migration laws, the central argument of this article is that Central American governments typically treated free migration not as a threat to sovereignty but as an opportunity to reinforce sovereignty over the fixed spaces through which people moved.

We report 27 planktonic and 21 benthic radiocarbon ages from the subtropical marine sediment core ODP Site 1063 (Bermuda Rise) for the time range between 30 and 14 ka before present. Despite low abundances of benthic specimens, it was possible to measure radiocarbon ages down to ∼10 µg carbon using a MICADAS and the gas ion source developed at ETH Zurich. Based on a tentative radiocarbon–independent age-model we found that the radiocarbon reservoir of the bottom water varied moderately relative to the analytical and age-model related uncertainties throughout the examined time-period, but larger differences in the radiocarbon reservoir appear to have affected the upper ocean layer. In particular, radiocarbon levels around Heinrich Stadial 2 reveal surface radiocarbon content similar to that of the atmosphere, while during Heinrich Stadial 1 surface waters were significantly depleted in 14C.

The October 2016 train accident on Cameroon’s main railway line remains shrouded in mystery. The announcement of the derailment before it happened, followed by a denial by the Minister of Transport a few hours later, at the very moment of the accident, has given rise to much speculation. According to testimonies collected in Eséka through fieldwork and the media, this tragic event was interpreted as the result of a witchcraft conspiracy. The inhabitants of the Bassa region, who consider the railway crossing their territory as a cultural heritage, had expressed their discontent with attempts to rationalize the line for some time. These accounts reveal that the disaster was triggered by collective action which unfolded through three distinct phases: labelling, whereby words acquire particular power; harbingers of misfortune; and finally, the bewitchment of the train to ‘zombify’ it, leading to its derailment. In response to these witchcraft imaginaries, the president himself addressed the Bassa’s grievances and requested an adjustment of the train stops, thus demonstrating the performativity of witchcraft and its capacity to put grievances on the agenda and to shape public policies. This article puts forward the idea that witchcraft represents a repertoire from which a community draws to express dissent. Bewitching and zombifying the train to make it derail are, for some actors, a way of signalling to the modern African state that it is not always ‘master in its own house’, that it does not have total control over reality and that it must constantly negotiate its authority.

At a time when the Parthenon Sculptures refuse to go away (in every sense of the phrase) and uncatalogued items were allegedly found to have been sold off by a member of staff, The British Museum needs some good news. There must have been sighs of relief all round when their new exhibition in the (itself often controversial: Puffett 2023) BP Gallery, Legion: life in the Roman Army, opened to almost universal press acclaim (e.g. Clark 2024; Jones 2024); it runs from 1 February to 23 June 2024. However, some (perfectly valid) observations in her blog by a scholar qualified in the field triggered a ‘woke alarm’ in some less-qualified quarters (McGrath 2024). It was always likely to be a crowd pleaser, with something for every “exercitologist” (Bishop 2014: 24), whether amateur or professional. For those visitors who had cut their Roman military teeth on Graham Webster's seminal Roman Imperial Army (Webster 1969, 1979, 1985), it was going to have its work cut out to satisfy.

In the mid-nineteenth century—even as many European liberals took a “turn to empire”—Mexican President Benito Juárez and his supporters enunciated an anti-imperial, liberal vision for international politics. In the context of the French intervention, Mexican liberals rejected claims that Europe’s material progress conferred upon the continent a “civilizing mission” vis-à-vis the rest of the world. Reconfiguring liberal and republican scripts, juaristas proposed an order legitimated by popular sovereignty and based on equality among states, non-intervention, and republican fraternity. This article situates juarista liberal internationalism in its historical context and in light of recent debates over liberalism’s longstanding entanglements with empire. By uncovering this overlooked strand of anti-imperial liberalism from the periphery, this article helps to decenter debates on liberal political thought and liberalism’s international implications. The juaristas’ rejoinder, we argue, should be integral to constructing a more pluralist and global understanding of the lineages of liberal internationalism.

For $2 \leq d \leq 5$, we show that the class of the Hurwitz space of smooth degree $d$, genus $g$ covers of $\mathbb {P}^1$ stabilizes in the Grothendieck ring of stacks as $g \to \infty$, and we give a formula for the limit. We also verify this stabilization when one imposes ramification conditions on the covers, and obtain a particularly simple answer for this limit when one restricts to simply branched covers.

Black and indigenous musics continue to evolve and dominate global markets and cultural spheres, notwithstanding a history of intellectual property theft and cultural appropriation. DJs and producers (by way of sampling or extrapolation) have played archival roles outside traditional music archiving. Colonial invasions and the transatlantic slave trade, as well as academic neocolonialism, displaced cultural histories imparted through oral traditions. The Black radical tradition resists global corporate capitalism, even within a music industry that emphasises stereotypical Black tropes for profit. Without regulation, the practices of museums, the education system and the music industry will be exacerbated by the development of recommendation systems and artificial intelligence (AI). Hence, in communities that have already suffered unjust intellectual and cultural property theft, I recognise and re-centre the archiving musico-cultural role that DJs and producers have historically played.

We aimed to determine the efficacy of different post-milking teat dips in the prevention of intramammary infection and teat condition scores in common crossbred cows (Holstein Frisian × Tharparkar) found in Indian sub-tropical conditions. Eighty healthy crossbred cows were selected and randomly divided into four groups: untreated control, 1% w/v iodine, 5% v/v lactic acid and finally essential oil mix (eucalyptus, lavender, peppermint, and tea tree oils). Samples were collected quarter-wise (n = 308). Sampling as well as teat scoring was done simultaneously. 1st sample was collected before starting teat dipping, followed by 15th day in milk (DIM), 45th DIM and 90th DIM, respectively. The study found that post-milking teat dipping significantly reduced the mean California mastitis test score, somatic cell count and electrical conductivity of the milk in the treatment groups compared to the control group, and also improved milk yield in the treatment groups. There were no differences between the individual treatments. The study also found a significant reduction in teat end condition and teat skin condition after 90 d of post-milking teat dipping.

This study aimed to elucidate the effects of various nutritional supplements on the physical, structural and sensory attributes of low-fat yogurt derived from camel milk, with the longer-term objective of enhancing its appeal and suitability for elderly consumers. Fresh camel milk was obtained from an Australian farm. Two yogurt variants were created: plain yogurt (CMY) and yogurt with added fructooligosaccharides, microbial transglutaminase (a ubiquitous food additive with potential health risks), apple pectin and linseed oil (CMYWA). The syneresis index of these yogurts was quantified through centrifugation, colour changes due to additives were assessed via colorimetric methods and both viscosity and granulometry were determined using precise instrumental techniques. After 7 d refrigerated storage, syneresis was 50% in CMY vs. 30% in CMYWA. Viscosity on day 7 was 205 mPa.s for CMYWA vs. 110 mPa.s for CMY. The CMYWA granule size increased from 2.1 μm on day 0 to 2.8 μm on day 14, while CMY granule size remained stable around 1.9 μm. Lactobacilli counts were higher in CMYWA at 2.8 × 107 CFU/g vs. 2.3 × 106 CFU/g in CMY. In a paired preference test with 37 consumers aged 18–65, CMYWA was significantly preferred over CMY. Sensory evaluations further substantiated that the yogurts with added supplements were more appealing to the palate. The results demonstrate the supplements improved camel milk yogurt properties.
