Recent research suggests that local exposure to refugees does not increase support for far-right parties. We challenge this null result by drawing on granular data from Berlin in the wake of the Syrian refugee crisis. While prior work in the German context has generally assumed that refugee exposure is exogenous at the local level, we demonstrate that refugee housing was disproportionately concentrated in neighborhoods with young, non-citizen residents. To address this selection bias, we harmonize in-person and mail-in precinct boundaries across elections and implement a difference-in-differences design with synthetic precincts. We find that localized exposure to refugee housing did increase support for the far-right in the 2017 federal elections. However, this backlash is geographically narrow in scope. Our findings nuance prior research by demonstrating that even if sociotropic concerns dominate electoral responses to the refugee crisis, voters’ responses are consistent with group threat theory at the local level.

Many countries have implemented a variety of pension reforms in response to the challenges posed by an aging population. These reforms typically involve a trade-off between ‘refinancing’ (i.e., increasing contributions) and ‘retrenchment’ (i.e., reducing benefits). The primary question addressed in this study is whether policymakers in the European Union (EU) possess the necessary capacity to sustain legislated pension reforms, particularly given the growing political influence of the elderly. To examine this issue, we develop a bargaining model designed to optimally allocate the economic burden of aging between successive cohorts of workers and retirees, incorporating retirement incentives. In a scenario where bargaining power remains constant, the optimal allocation rule dictates a fixed-contribution system, effectively shifting the full burden of aging onto the elderly. However, when bargaining power is allowed to fluctuate in response to changes in the relative size of the retiree population (i.e., the dependency rate), the optimal allocation rule involves a compromise between increasing contributions and reducing benefits. In the empirical analysis, we compare these theoretical optimal allocation rules with projections of pension benefit rates and dependency ratios from the 2021 Economic Policy Committee. By calculating the implicit bargaining power required to align projected pension benefits with the optimal sharing rule for each year, we demonstrate a growing divergence between projected pension benefits and the optimal levels in many EU countries, as demographic shifts progress. Furthermore, our findings indicate that for most countries, projected pension benefits are increasingly falling below optimal levels when bargaining power adjusts in accordance with population aging.

To anticipate relationships between future climate change and societal violence, we need theory to establish causal links and case studies to estimate interactions between driving forces. Here, we couple evolutionary ecology with a machine-learning statistical approach to investigate the long-term effects of climate change, population growth, and inequality on intergroup conflict among farmers in the North American Southwest. Through field investigations, we generate a new archaeological dataset of farming settlements in the Bears Ears National Monument spanning 1,300 years (0 to AD 1300) to evaluate the direct and interactive effects of precipitation, temperature, climate shocks, demography, and wealth inequality on habitation site defensibility—our proxy for intergroup conflict. We find that conflict peaked during dry, warm intervals when population density and inequality were highest. Results support our theoretical predictions and suggest cascading effects, whereby xeric conditions favored population aggregation into an increasingly small, heterogenous area, which increased resource stress and inequality and promoted intergroup conflict over limited productive patches. This dynamic likely initiated feedback loops, whereby conflict exacerbated shortfalls and fostered mistrust, which drove further aggregation and competition. Results reveal complex interactions among socioclimatological conditions, all of which may have contributed to regional depopulation during the thirteenth century AD.

Teaching introductory courses on the ancient world is a study in reviewing a vast field of material without compromising on nuance. It is a tightrope walk, especially when beginning a teaching career. Comedy and economics are topics often parsed in more advanced courses to engage the primary source materials and modern debates with appropriate depth of analysis. However, their place in the introductory classroom is an essential aspect of understanding the ancient Greek world fully. Especially as students often struggle to find ancient comedy amusing upon first interaction, teaching these topics is a process of trial and error for the professor, who is often constrained by their own exposure to these topics. This article shares a classroom activity on comedy and economic institutions designed for the introductory class, engaging students by activating prior knowledge and practicing close reading of a selection from an ancient text.

We define a natural notion of standard translation for the formulas of conditional logic which is analogous to the standard translation of modal formulas into the first-order logic. We briefly show that this translation works (modulo a lightweight first-order encoding of the conditional models) for the minimal classical conditional logic $\mathsf {CK}$ introduced by Brian Chellas in [3]; however, the main result of the article is that a classically equivalent reformulation of these notions (i.e., of standard translation plus theory of conditional models) also faithfully embeds the basic Nelsonian conditional logic $\mathsf {N4CK}$, introduced in [11] into $\mathsf {QN4}$, the paraconsistent variant of Nelson’s first-order logic of strong negation. Thus $\mathsf {N4CK}$ is the logic induced by the Nelsonian reading of the classical Chellas semantics of conditionals and can, therefore, be considered a faithful analogue of $\mathsf {CK}$ on the non-classical basis provided by the propositional fragment of $\mathsf {QN4}$. Moreover, the methods used to prove our main result can be easily adapted to the case of modal logic, which makes it possible to improve an older result [10, Proposition 7] by S. Odintsov and H. Wansing about the standard translation embedding of the Nelsonian modal logic $\mathsf {FSK}^d$ into $\mathsf {QN4}$.

Vowel deletion is frequent in the Chichicastenango dialect of K’iche’ (Maya). Whereas deletion in content words is reportedly predictable based on vowel quality, syllable structure and stress, deletion in function words is much more variable. This article investigates vowel deletion in a corpus of spontaneous, monologic speech. The results show that deletion in content words is highly regular, occurring to lax vowels in unstressed, CV syllables adjacent to the stressed syllable. A difference can be observed between vowels belonging to stress domain internal morphemes and extrametrical morphemes. Deletion in extrametrical morphemes is somewhat less regular, and does not occur in word-final syllables. In function words, vowel deletion is sensitive to similar conditions to those that affect content words, but is highly variable and is influenced by the phrase-level context.

Wide diversity in plant adaptive traits, such as seed size and dormancy, is generally linked to the rapid spread, invasiveness, and adaptative potential of a weed species. Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husnot] is a significant weed species in winter crops such as wheat (Triticum aestivum L.) and summer crops such as corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and peanut (Arachis hypogaea L.) in Alabama. In this study, diversity in seed morpho-physiological traits—such as seed length, awn length, seedling length, 100-seed weight, and seed dormancy—was assessed in 65 L. perenne ssp. multiflorum populations collected from Alabama in 2023. Significant diversity was observed among the populations for 100-seed weight (61.8 to 295.8 mg), seed length (3.5 to 6.43 mm), awn length (0 to 7 mm), and seedling length (0.5 to 38.6 cm). Germination speed was significantly lower in the populations with high initial seed dormancy (>30%) compared with medium (15% to 30%) and low dormancy groups (<15%) at 0 and 3 mo after harvesting. Additionally, the relationship between herbicide-resistance status and seed morpho-physiological traits in these populations was explored. A significant positive association was observed between seed dormancy and the number of survivors following glyphosate (P < 0.01) and clethodim (P < 0.01) treatments. The observed diversity in morpho-physiological traits could be the reason for enhanced adaptability of L. perenne ssp. multiflorum, and its correlation with herbicide resistance indicates directional selection or coexistence of specific seed morpho-physiological traits with herbicide resistance under the repeated use of similar modes of action.

Extant work shows that generative AI such as GPT-3.5 and perpetuate social stereotypes and biases. A less explored source of bias is ideology: do GPT models take ideological stances on politically sensitive topics? We develop a novel approach to identify ideological bias and show that it can originate in both the training data and the filtering algorithm. Using linguistic variation across countries with contrasting political attitudes, we evaluate average GPT responses in those languages. GPT output is more conservative in languages conservative societies (polish) and more liberal in languages used in liberal ones (Swedish). These differences persist from GPT-3.5 to GPT-4. We conclude that high-quality, curated training data are essential for reducing bias.

Michael Blake, Yuna Blajer de la Garza, and Alex Zakaras offer insightful critiques of several arguments central to my book Beyond the Law’s Reach? In the process, they raise large questions in political philosophy more generally, especially as it pertains to global affairs. Blake is skeptical about the distinction, driving much of the book, between consolidated liberal democracies and jurisdictions where the “shadow of violence” prevails. Blajer de la Garza worries that the international reparative duties that the book highlights may linger indefinitely, and, consequently, be exploited by cynical political actors. Finally, whereas Beyond the Law’s Reach? argues that liberal democracies’ collective integrity is affected by their entanglement in violence and corruption abroad, Zakaras doubts whether this collective moral problem carries over into the individual level, given individual citizens’ reasonable ignorance of policy details. I offer responses to each of these critiques in turn. I conclude by highlighting the picture of democratic civic responsibility that emerges from these responses.

Public communication about antimicrobial resistance (AMR) is widely acknowledged as a cornerstone of global, national, and regional strategies to tackle this urgent health threat. However, much like AMR itself, efforts to communicate about it are hindered by complex and intersecting challenges. This scoping review synthesises insights from 88 scholarly manuscripts published between 2015 and 2024 to explore critical issues in AMR communication and identify potential options to address them. We distil nine overarching themes that underpin effective public communication and engagement, with particular significance for engaging with disadvantaged and vulnerable communities. These themes encompass (1) social science theoretical frameworks, (2) varied sociocultural contexts, (3) public engagement and dialogue, (4) linguistic considerations, (5) messaging strategies, (6) media use and its impacts, (7) large-scale public campaigns, (8) creative communication approaches, and (9) evaluation. We discuss each theme and outline related recommendations, collectively advocating a re-imagining of AMR communication as a civic, cultural, and reflexive practice that is attuned to the complexities of diverse contexts and cultures, and designed to enhance societal relevance and impact.

Sri Lanka is immersed in the ideology of Buddhist primacy: “the island belongs to its Sinhala Buddhists, and Buddhism should dominate the state.” Why does this ideology attract? The standard answer is that it justifies the power of the Sinhala Buddhist ethnic group. This article offers a different take through two contestations of modernity. It draws from Sabhyatva Rajya Kara or Towards a Civilisation-State by the Sinhala public intellectual Gunadasa Amarasekara, and the work of post-secular thinkers such as Jurgen Habermas, Charles Taylor, and Nicholas Wolterstorff, and argues that, along with power, Buddhist primacy attracts because it offers an invitation to join a dignifying, heroic narrative, and a vision of “fullness.” That is, there is more to Buddhist primacy than power. This points to the need for a richer human anthropology, and a fuller account of religion, in studies of religion and constitutions.

What is the value of public philosophy? “Philosopher-first” accounts suggest that the ideas that academic philosophers produce can, when disseminated, be useful to the wider public. However, such accounts assume that there is a gap between the interests and activities of professional philosophers and those of the wider public, which must be overcome by translating philosophy into more accessible terms. This article offers an alternative account—the “public-first” account. On this account, philosophy is a necessary part of everyday life. Each of us relies upon a background of conceptual resources that shape our interpretations, expectations, and behaviours in the world. Professional philosophers might be useful in analysing, maintaining, and fixing our conceptual infrastructure. However, there is no gap between philosophy and everyday life, which must be overcome. Whilst most defences of public philosophy argue that it is beneficial to the public, on the “public-first” account, public philosophy is also vital for the discipline of philosophy itself. If philosophers want to adequately evaluate their philosophical theories, they must appeal to a much wider and more diverse range of human experience than that of professional philosophers themselves. As such, public philosophy is necessary for properly conducted philosophical inquiry.
