An abundance and diverse range of prehistoric fishing practices was revealed during excavations between 2012 and 2022 at the construction site of the Femern Belt Tunnel, linking the islands of Lolland (Denmark) and Femern (Germany). The waterlogged parts of the prehistoric Syltholm Fjord yielded well preserved organic materials, including the remains of wooden fish traps and weirs, and numerous vertical stakes and posts driven into the former seabed – evidence of long term fishing practices using stationary wooden structures from the Mesolithic to the Bronze Age (c. 4700–900 cal BC). Here, we present the results of a detailed study on these stationary wooden fishing structures, making this the most comprehensive and detailed description of prehistoric passive fishing practices in Syltholm Fjord to date. The exceptional scale of the excavated area (57 ha) and abundance of organic materials encountered during excavations provides us with a rare opportunity to identify individual weir systems and information on their construction, maintenance, and use. To contextualise further, we provide an up-to-date compilation of comparable finds in the Danish archaeological record, including a dataset of directly dated specimens, based on both published and unpublished sources. Our results show that stationary wooden fishing structures are an invaluable archaeological resource, and their study, combining landscape reconstruction, ethnographic analogy, and fishing technology, together with artefactual evidence and radiocarbon dating, allows us to reconstruct prehistoric fishing strategies in depth. Due to the long chronology and diversity of the study materials, our results complement previous research on the many nuances and regional specificities of the persistence of fishing practices in the western Baltic Sea over time, despite introductions of new cultures, populations, and livelihoods. Finally, we emphasise that the Neolithisation process in Northern Europe was not as straightforward and uniform in terms of subsistence as commonly assumed.

Much of the existing philosophical literature on BDSM focuses on questions about the ethics of BDSM. But there is an underlying question here regarding the nature of BDSM, one which remains largely unaddressed. In this paper, I take that metaphysical question to be prior to the normative one. In other words: it will be important to have a clear view of what BDSM is before we go on to evaluate it. Accordingly, this is a paper about the nature of BDSM and BDSM activities: what they are like, what makes them unique, and the ways in which these activities might be valuable. Here, I work from the philosophical literature on games to analyze structured erotic encounters (or “scenes”) in BDSM. In the first half of the paper, I argue that BDSM scenes are games, and that understanding them in this way yields important insights into the roles of agency, autonomy, and value in BDSM. In the second half of the paper, I map points of connection between this view of scenes-as-games and the existing literature on BDSM in sexual ethics, in order to illuminate the ways in which a moral evaluation of BDSM scenes might proceed from this analysis.

One of the main features of Gilles Deleuze’s lectures of 1981 concerns the importance accorded to the notion of modulation as a philosophical definition of painting. The novelty of such a framework lies in the correspondences established between analogical operations and artistic spaces of Western art. This article establishes the main moments of this analysis and thus point out its main technical, historical, and aesthetic implications. Ultimately, the notion of modulation is considered as the conceptual operator of a “heterogenetic” history of art within the framework of Deleuze’s philosophy.

We are all capable of arriving at views that are driven by corrupting non-epistemic interests. But we are nonetheless very skilled at performing a commitment to epistemic goods in such cases. I call this the “Problem of Mere Epistemic Performance,” and it generates a need to determine when these commitments are illusory and when they are in fact genuine. I argue that changing one’s mind, when done in response to the evidence and at a likely cost to oneself, is the best indication that an agent is committed to epistemic goods and that they are genuinely in the game of giving and asking for reasons. This is because changing one’s mind in this way goes as far as we can in eliminating the possibility that the agent has an ulterior motivation for their epistemic practices. Moreover, this account shows that the consensus view of the ideal epistemic agent is mistaken. The ideal agent must have false beliefs or deficient epistemic practices because only then do they have the opportunity to change their mind and establish a commitment to epistemic goods – a commitment that even an agent with only true beliefs and maximal justification or understanding may lack.

Motivated by the study of algebraic classes in mixed characteristic, we define a countable subalgebra of ${\overline {\mathbb {Q}}}_p$ which we call the algebra of André’s p-adic periods. The classical Tannakian formalism cannot be used to study these new periods. Instead, inspired by ideas of Drinfel’d on the Plücker embedding and further developed by Haines, we produce an adapted Tannakian setting which allows us to bound the transcendence degree of André’s p-adic periods and to formulate the p-adic analog of the Grothendieck period conjecture. We exhibit several examples where special values of classical p-adic functions appear as André’s p-adic periods, and we relate these new conjectures to some classical problems on algebraic classes.

The secessionist state of Biafra enacted a propaganda campaign that simultaneously built support for its war of independence (the Nigerian Civil War, 1967–1970) and fostered nationalism. Integral to this effort, although understudied, were the currency, stamps, posters, and cartoons artists produced while working for the government. Putting these materials in dialogue with print and radio propaganda, and the Ahiara Declaration (the culminating treatise of Biafran nationalism), this article demonstrates how visual propaganda actualized a nation, constructed national identity, positioned Biafra as a foil to an irredeemable Nigeria, and defined a citizenry. Through the materials they created, artists shaped Biafra’s national consciousness.

Impact dynamics have long fascinated due to their ubiquity in everyday phenomena, from rain droplets splashing on windscreens to stone-skimming on the surface of the ocean. Impacts are characterized by rapid changes over disparate length scales, which make them expensive or sensitive to capture experimentally and computationally. Here, reduced mathematical models come to the fore, offering a way to get significant physical insight at reduced cost. In this volume, Phillips & Milewski (J. Fluid Mech., 2024) develop a mathematical model allowing for air–water interactions in the low-impact speed regime, in which an impactor bounces or rebounds rather than splashes. Their model offers a reliable way to capture air effects in bouncing, with a range of potential applications including hydrodynamic-quantum analogues and biomimetic water walkers.

Physician databases constitute an essential component of health workforce planning. However, while some countries have established functioning national physician databases, others have failed to do so. We compared the healthcare systems of two technologically and economically developed countries, Canada and Israel, which represent cases of respective success and failure in establishing physician databases. A comparative analysis was conducted using a historical-institutionalist approach to examine contemporary health policy outcomes. White papers, studies on healthcare human resources, and reports by professional committees were examined to explore the aims, interests, positions, and actions of stakeholders. In Canada, state–medical profession cooperation, deep-rooted in a longstanding regulatory bargain between the two parties, has facilitated the creation and management of physician databases, albeit limited and in need of urgent improvement, on national and jurisdictional levels. The lack of such regulatory arrangement coupled with enduring conflicted relations between stakeholders due to particular historical developments have hindered the development of an Israeli equivalent database so far. Finally, health policy outcomes may be explained against the backdrop of broader political, governance, and organisational contexts. How medical organisations respond to governmental healthcare initiatives is heavily influenced by their institutional position vis-à-vis the state, shaped by historical processes and regulatory arrangements.

By adopting a pre- and post-test design, the current study longitudinally examined the complex relationship between two different dimensions of phonological vocabulary knowledge (declarative vs. automatized) and their ultimate impacts on global L2 listening proficiency among 133 Japanese EFL students. The declarative group focused solely on what target words sound like and mean via meaning recognition tasks. The automatization group worked not only on such form-meaning mappings but also on prompt access to the target words in a semantically, collocationally, and grammatically appropriate manner via lexicosemantic judgment tasks. Compared to the declarative group, the automatization group showed relatively robust learning in both declarative and automatized dimensions of target words. Although neither training approach showed clear superiority, the results suggest that relative gains in automatized, rather than declarative, dimensions are associated with enhanced L2 listening proficiency. The distinction between declarative and automatized dimensions of phonological vocabulary knowledge, along with the absence of a direct link between training type and improved listening proficiency, offers valuable insights for future extension studies.

The spotted hyaena Crocuta crocuta is relatively understudied across its range despite evidence of widespread declines. It is therefore essential that robust baseline population density assessments are conducted to inform current management and future conservation policy. In Mozambique this is urgent as decades of armed conflict followed by unchecked poaching have resulted in large-scale wildlife declines and extirpations. We conducted the first robust population density estimate for a spotted hyaena population in Mozambique using spatially explicit capture–recapture methodologies. We recorded a relatively low population density of 0.8–2.1 hyaenas/100 km2 in the wildlife management area Coutada 11 in the Zambezi Delta of central Mozambique in 2021. These densities are well below the estimated carrying capacity for the landscape and are comparable to published densities in high human-impact, miombo woodland-dominated and arid environments. The combination of historical armed conflict, marginal trophy hunting and bushmeat poaching using wire snares and gin traps (with physical injuries evident in 9% of identified individuals) presents persistent anthropogenic pressure, limiting the post-war recovery of this resident hyaena population. We provide insights into the dynamics of hyaena population status and recovery in such post-war landscapes, adding to mounting evidence that the species is less resilient to severe anthropogenic disturbances than previously believed. We recommend long-term monitoring of this and other carnivore populations in post-war landscapes to ascertain demographic trends and implement effective conservation interventions for population recovery.

Legislative term limits garnered public support because they promised to drain the swamp, removing entrenched incumbents from office. There is often a partisan dimension to this appeal since “the swamp” that is to be “drained” has often been controlled by one party for a lengthy period. However, it remains unclear to what extent term limits realign partisanship within US state legislatures. Using newly available turnover data, this research evaluates how legislative partisanship shifted after the implementation of term limits in state legislatures and continued over 20 years. The initial surge effects of term limits did appear to level the playing field between parties. The passage of term limits reversed party majorities in state legislatures, primarily benefiting newfound Republican majorities. These findings have important implications for current understandings of legislative term limits, as more states revisit these proposals, and provide insight into party trends at the state legislative level.

Discussions of term limits are happening in the United States and abroad. In July 2024, President Biden announced his support for limiting the number of years that federal judges may serve. Surveys suggest that limits for judges are popular with Americans.1 Relatedly, voters have historically supported term limits for members of Congress, with the most recent survey (from July 2023) finding support among 87%.2 For now, limits are unlikely to be imposed on federal judges or members of Congress, but there are recent changes in the states. Voters in North Dakota imposed limits on their state legislators in 2022, and those limits will take effect in 2028. In Michigan, also in 2022, voters shortened the long-standing lifetime limits for their legislators from 14 to 12 years. Discussions or reforms, including the elimination of limits, have also occurred outside of the United States. In Russia, voters seemingly reset the term limits that applied previously to President Vladimir Putin, thereby allowing him to serve in office until 2036. In China, where limits for various leaders including the president were first added to the country’s constitution in 1982, limits were abolished in 2018. Although these are prominent examples of limits being lifted, a remarkable number of new limits have been enacted elsewhere, with limits on executives being imposed in 17 countries within the past decade alone. To date, only a handful of countries, most of which are in the Americas, have legislative limits.3 Conversely, nearly every country limits the service of judges.4

Flavonoids are a key class of polyphenols, i.e., phytochemical compounds present in foods and beverages, which have been described as having health benefits in preventing several chronic diseases. Estimating flavonoid intake has already been conducted in several countries but has yet to be performed in Portugal. This study included 5,005 participants aged 3-84 years and aimed to estimate dietary flavonoid intake in the Portuguese population, using data from the National Food and Physical Activity Survey 2015-2016, providing information on intake, main food contributors, and the socio-demographic factors associated with the intake. Food intake data from the Survey was converted to flavonoid intake using a database built to include the most updated USDA databases on flavonoids, isoflavones and proanthocyanidins, and the Phenol-Explorer database. The rationale for combining food consumption data and different flavonoid databases using the FoodEx2 classification system was established. Linear regressions assessed the associations between socio-demographic factors and dietary flavonoid intake. The total flavonoid intake of the Portuguese population was estimated to be 107.3 mg/day. Flavanols were the most representative subclass, followed by flavonols, anthocyanidins, flavanones, flavones and isoflavones. Fruits and vegetables were the primary food contributors, providing 31.5% and 12.4% of the total flavonoid intake. Adolescents had the lowest total flavonoid intake, and older adults had the highest. This study provides information on the Portuguese population’s dietary flavonoids, allowing for international comparisons. It can also streamline forthcoming investigations into the link between flavonoid consumption and its impact on health, contributing to the future establishment of dietary reference values.

This article traces the conceptual history of key terms used to describe and criticize bad political regimes, focusing on the displacement of “tyranny” by “dictatorship” and “authoritarianism.” Classical Greek thought understood tyranny primarily in terms of the character of rulers, whereas the modern idea of dictatorship emerged from a Roman conceptual framework that focused on authority and its legitimation. New problems of legitimation in the eighteenth and nineteenth centuries diminished the utility of the character-centric concept of tyranny and increased the fruitfulness of dictatorship for political analysis. The emergence of the modern state in the nineteenth century shaped the conceptual field by increasing the salience of problems concerning the appropriation or usurpation of sovereignty, the distortion of popular legitimation and accountability, and the incentives for submission to illegitimate orders. I conclude that the use of “authoritarianism” is likely to increase in prominence, but that retaining multiple regime concepts enriches analysis.

As the Arctic warms and growing seasons start to lengthen, governments and producers are speculating about northern “climate-driven agricultural frontiers” as a potential solution to food insecurity. One of the central ecological factors in northern spaces, however, is permafrost (perennial frozen ground), which can drive cascading environmental changes upon thaw. Considering the land requirements for expanded agriculture and the unique challenges of northern farming, national and subnational governments are grappling with and facilitating this speculative boom in different ways. Analysing agricultural land use policy instruments from the US State of Alaska and the Republic of Sakha (Yakutia) in Russia, this paper investigates if and how permafrost factors into their legal frameworks and what impacts this has on agricultural development, conservation, and food security. Alaska and the Republic of Sakha were chosen for reasons including both having at least 100 years of agricultural history on permafrost soils, both containing extensive amounts of permafrost within their landmasses and both containing permafrost that is ice-rich. Comparing legal texts as indicative of state capacities and strategies to govern, the paper finds that the two regions diverge in how they understand and regulate permafrost, and suggests that these approaches could benefit from one another. Bringing together geoclimatic and sociocultural concerns to problematise static policy divisions, this paper gestures to a path forward wherein subnational policy can balance needs for food, environmental, and cultural security in the North.

Although it is largely overlooked, Thomas Hobbes spent the final years of his life translating Homer’s epic poetry. Despite an overwhelmingly popular extant English edition of the Iliad by George Chapman, Hobbes chose to proffer his own account, often taking great liberties with the source material. Juxtaposed against Chapman’s translation, we see that Hobbes implicitly critiques the political philosophy it commends—a philosophy which disrespects kingly power, misunderstands sovereign authority, and abdicates human virtue. Hobbes sees these elements as corrupting the poetic imagination of England, precipitating much of the unrest we see in the seventeenth century. In correcting and reframing these tales for a new world, Hobbes provides a moral scaffolding for his political philosophy through one of the most widely read classical texts of his time.

An existing approach for deriving analytical expressions for slip-flow properties of Stokes flow is generalised and applied to a range of micro and nanoscale applications. The technique, which exploits the reciprocal theorem, can generate first-order predictions of the impact of Navier or Maxwell slip boundary conditions on surface moments of the traction force (e.g. on drag and torque). This article brings dedicated focus to the technique, generalises it to predict first-order slip effects on arbitrary moments of the surface traction, numerically verifies the technique on a number of cases and applies the method to a range of micro and nano-scale applications. Applications include predicting: the drag on translating spheres with varying slip length; the efficiency of a micro journal bearing; the speed of a self-propelled particle (a ‘squirmer’); and the pressure drop required to drive flow through long, straight micro/nano channels. Certain general results are also obtained. For example, for low-slip Stokes flow: any surface distribution of positive slip length will reduce the drag on any translating particle; and any perimetric distribution of positive slip length will reduce the pressure loss through a straight channel flow of arbitrary cross-section.
