This study presents a revised estimation of the prevalence of female genital mutilation/cutting (FGM/C) among migrant women and second-generation girls in Italy as of 1 January 2023. The study is based on an enhanced indirect estimation of the prevalence among migrants and data on first- and second-generation women legally residing in Italy as of 1 January 2023. The study estimates that approximately 88,600 women aged 15 and over have undergone FGM/C in Italy, representing 46% of migrant women from practising countries. Notably, around one-third of these women are over 50 years old, indicating that FGM/C remains a significant health concern beyond childbearing age. Among foreign-born women, 46.5% are estimated to be affected, compared to 22.5% of Italian-born women. The research also identifies approximately 16,000 girls under 15 at potential risk, with the highest numbers among those of Egyptian, Nigerian, and Senegalese descent. Methodologically, the study underscores the importance of refining indirect estimation techniques to account for the socio-demographic selectivity of migration. While the overall prevalence of FGM/C is decreasing, the persistence of the practice among specific communities calls for targeted interventions. The findings emphasise the need for culturally sensitive awareness campaigns, strengthened legal frameworks, and accessible healthcare services. Furthermore, this research contributes to the European discourse on FGM/C by providing a replicable estimation model adaptable to other non-practising countries receiving migrants from FGM/C-prevalent regions. Periodic replication of such estimates can provide valuable insights into evolving FGM/C trends, aiding policymakers in resource allocation and intervention strategies to eradicate the practice.

Let $M^{({k})}_{d}(n)$ be the manifold of n-tuples $(x_1,\ldots,x_n)\in(\mathbb{R}^d)^n$ having non-k-equal coordinates. We show that, for $d\geq2$, $M^{({3})}_{d}(n)$ is rationally formal if and only if $n\leq6$. This stands in sharp contrast with the fact that all classical configuration spaces $M^{({2})}_d(n)=\text{Conf}(\mathbb{R}^d,n)$ are rationally formal, just as are all complements of arrangements of arbitrary complex subspaces with geometric lattice of intersections. The rational non-formality of $M^{({3})}_{d}(n)$ for $n \gt 6$ is established via detection of non-trivial triple Massey products, which are assessed geometrically through Poincaré duality.

A 9200-year-long Holocene record of pollen, magnetic susceptibility (MS), and sedimentation rates from Pup Lake, northern Lower Michigan, USA, along with comparative pollen data from regional paleoecological sites and optically stimulated luminescence dates from inland sand dunes across the Great Lakes region, reveals emerging relationships among climate, vegetation, and erosion. Tsuga (hemlock) pollen was used to track local- and regional-scale hydroclimate variability owing to the taxon’s moisture sensitivity and close association with modern lake-effect snowfall gradients. Two periods of elevated MS and Tsuga values, 6800–5200 cal yr BP and 3200–800 cal yr BP, are interpreted as millennial-scale phases of greater effective moisture that drove key changes in forest composition and resulted in accelerated erosion. Overall, the lake’s MS record broadly tracks changes in Tsuga pollen frequencies and sedimentation rates, particularly during the Late Holocene, suggesting the emergence of a well-defined lake-effect climate system between 5200 and 1000 cal yr BP. Additionally, Pup Lake’s MS record exhibits notable connections with widely recognized hemispheric-scale climate deterioration episodes, including the 9.2, 8.2, and 5.2 ka BP events.

We obtain polylogarithmic bounds in the polynomial Szemerédi theorem when the polynomials have distinct degrees and zero constant terms. Specifically, let $P_1, \dots, P_m \in \mathbb Z[y]$ be polynomials with distinct degrees, each having zero constant term. Then there exists a constant $c = c(P_1,\dots,P_m) \gt 0$ such that any subset $A \subset \{1,2,\dots,N\}$ of density at least $(\log N)^{-c}$ contains a nontrivial polynomial progression of the form $x, x+P_1(y), \dots, x+P_m(y)$. In addition, we prove an effective “popular” version, showing that every dense subset $A$ has some non-zero $y$ such that the number of polynomial progressions in $A$ with this difference $y$ is asymptotically at least as large as in a random set of the same density as $A$.

In this article, I analyse the word-prosodic system of Drubea and Numèè, two of the rare tonal Oceanic languages. Building on Rivierre’s (1973) seminal work, I show that the word-prosodic system of these two languages can be analysed as involving only register features: an underlying downstep and a postlexical epenthetic upstep. Drubea and Numèè are thus tonal languages without tones stricto sensu. This new type of word-prosodic system has both theoretical and typological implications: (i) register features, defined as in Snider’s (1999) Register Tier Theory, need not be subordinate to or associated with tones, and may exist in the absence of tone, including in underlying representation; (ii) tonal systems come in two types: tone-based systems in which the tonal contrasts are defined paradigmatically, as in most tone languages, and register-based systems where tonal contrasts are defined syntagmatically, as in Drubea and Numèè.

The best known historical narrative of the international mental hygiene movement among English-speaking audiences locates its origins in the publication of A Mind That Found Itself, the autobiographical account of Clifford Beers (1876–1943), a Yale graduate and former psychiatric patient. The success of the book is thought to have prompted the creation of the first Society for Mental Hygiene in Connecticut in 1908. Beers’ biography, published as Advocate for the Insane in 1980, contends that mental hygiene abroad developed from seeds first sown in the USA and subsequently in Canada.

This article offers a critical reappraisal of that narrative and advances an alternative framework for understanding the history of the international mental hygiene movement during the first half of the twentieth century. It draws on a body of scholarship, emerging since the 1980s, that has sought to decentre the prevailing account, exposing the multiplicity of forces at work in a history that diverges from any straightforward, linear trajectory radiating from a single point of origin.

By tracing this decentred history, the article highlights the contested nature of the ‘international’ in the context of the mental hygiene movement. Case studies from the USA, France, Brazil, and Argentina reveal both the conflicts it engendered and the diverse meanings and significance it assumed within distinct national settings.

Do initiative and referendum campaigns enable voters to make coherent decisions? Do the dynamics of opinion formation differ across ballot measures? Despite extensive research on direct democratic processes, these questions remain underexplored. Using rolling cross-section data on two citizen-sponsored initiatives in California and two referendums in Switzerland, we examine the dynamics of voters’ knowledge about party cues and arguments for and against ballot measures in the run-up to direct democratic votes. Moreover, we assess the extent to which these dynamics help voters to cast votes that are in line with their party cue and consistent with their position on arguments. The results present a nuanced picture: while campaigns increase voters’ knowledge and help them to make more coherent choices, there is significant variation across ballots in knowledge acquisition and resulting degree of in-line and consistent voting.

This study examined data from 20 national genebanks in Latin America and the Caribbean, Africa, the Near East and Asia to identify similarities and differences in genebank operations and processes, funding and facilities, as well as opportunities to strengthen their contributions to the global system of crop conservation and use. Data on genebank performance metrics were collected and used to assess compliance with FAO Genebank Standards. This enabled the analysis of trends in ex situ conservation of major food crops, locally important crops and crop wild relatives across national genebanks and the identification of shared challenges and opportunities to improve genebank operations and address funding gaps. All genebanks in the study failed to meet quality management standards and performance goals for the effective management of crop collections. The most pressing challenge for all national genebanks was the management and safety duplication of highly diverse collections in both seed and field genebanks, often with limited information available to guide best conservation practices. A further critical constraint was the fluctuating and often insufficient funding to support the wide range of tasks needed to secure and use this valuable national crop germplasm.

Production of seafood has received relatively little attention in agri-food debates despite the fact that, since the 1960s, seafood production has been transformed through the industrialization of fisheries and globalization of seafood commodity chains. Intensive aquaculture emerged as a new industry in response to declining fish catches. Global commodity chains of seafood and capital accumulation processes changed tremendously, leading to complex international trade dynamics and rising inequalities. The Turkish aquaculture sector has also been transformed via government subsidies, and a few vertically integrated aquaculture companies started to produce farmed sea bass and sea bream (SBSB) in Turkish waters, while organizing their operations both upstream (processing of fish feed in Africa) and downstream (sales and distribution in Europe) in the global SBSB value chain. We adopted a single commodity approach to uncover how seafood production has been transformed via expanding commodity frontiers of capital-intensive SBSB production by focusing on the strategies of Turkish aquaculture enterprises, trade dynamics, and socio-ecological implications of SBSB production via in-depth interviews with key stakeholders and a review of legislative documents and trade data. Our analysis offers critical insights into the agrarian-change debate in Turkey by analyzing the global and regional socio-ecological inequalities created by Turkish SBSB production.

Compliance with court decisions is essential for the rule of law. Generally, regimes comply with decisions that serve their interests; however, compliance with decisions against government interests is less certain. In 1947–2005 and 2014–2023, the Supreme Court of Pakistan (SCP) decided many politically important cases in favour of the prevailing authoritarian and hybrid regimes. However, between 2005 and 2013, although the SCP reached decisions against the government’s interests in politically important cases, the government still complied. Why would authoritarian and hybrid regimes, such as those in Pakistan between 2005 and 2013, comply with decisions in politically important cases that were against their interests instead of disobeying or ignoring them? Very few studies have addressed this puzzling phenomenon. This article argues that increasing public support for courts coupled with reinforcement mechanisms—supported by both the judiciary and external actors—contributes to such compliance. The article concludes that a combination of social, political, and legal factors is essential for compliance by authoritarian and hybrid regimes in politically important cases.

A classical theorem of Jordan asserts that if a group G acts transitively on a finite set of size at least $2$, then G contains a derangement (a fixed-point free element). Generalisations of Jordan’s theorem have been studied extensively, due in part to their applications in graph theory, number theory and topology. We address a generalisation conjectured recently by Ellis and Harper [‘Orbits of permutation groups with no derangements’, Preprint, 2024, arXiv:2408.16064], which says that if G has exactly two orbits and those orbits have equal length $n \geq 2$, then G contains a derangement. We prove this conjecture in the case where n is a product of two primes, and in the case where $n=bp$ with p a prime and $2b\leq p$. We also verify the conjecture computationally for $n \leq 30$.

Bibliometric analysis reveals significant research trends and highlights collaborations among institutions and countries within extremophiles and astrobiology. A bibliometric analysis of 309 papers reveals key research trends and collaborations in extremophiles and astrobiology in this research and provides a strategic overview of scientific interest, identifying research gaps and guiding future exploration of life adaptability and extraterrestrial biosignatures. Thus, analysis has systematically assessed trends, research collaborations and emerging topics guiding future research on the adaptability of life and the search for extraterrestrial biosignatures. According to trends, omics technologies, particularly genomics and multi-omics approaches, are emerging as pivotal tools for understanding the genetic and metabolic adaptations that enable extremophiles to thrive in harsh conditions. Also, multi-omics approaches will provide a better understanding of the genetic and metabolic adaptations that allow extremophiles to survive in harsh environments, such as extreme temperatures, high salinity, or acidic and alkaline conditions. These insights deepen our understanding of extremophile biology and support the identification of molecular biosignatures indicative of extraterrestrial life.

A growing body of evidence shows an association between in utero Ramadan exposure and negative long-term consequences. Nonetheless, there is a scarcity of studies utilizing clinical measures in adults. This study investigates a possible association between in utero Ramadan exposure and mean arterial pressure (MAP) as well as random blood glucose (RBG) measures in the adult offspring. Using cross-sectional data from the Southeast Asia community observatory health and demographic surveillance system (SEACO) in Malaysia for two survey rounds (year 2013 and 2018), we compared MAP and RBG of in utero Ramadan-exposed Muslims with unexposed Muslims and non-Muslims. In utero Ramadan exposure was estimated based on the overlap between pregnancy (estimated from birth dates) and Ramadan periods. We conducted difference-in-differences analyses adjusted for age and birth months (seasonal effects). A total of 20,575 participants aged 35 or older were included in the analysis, comprising 12,696 Muslims and 7,879 non-Muslims. Difference-in-differences analyses revealed no statistically significant association between in utero Ramadan exposure and MAP, or between in utero Ramadan and RBG. These findings persisted in additional analyses examining the timing of Ramadan exposure during pregnancy.
