A bottlenose dolphin, Tursiops sp., stranded on the coast of South Carolina, USA was found to be heavily infected in its intestine by tapeworms, which we identified molecularly. Sequencing of portions of the mitochondrial cytochrome c oxidase I (COI) and nuclear large subunit ribosomal RNA (28S rRNA) genes showed the cestodes to be Diphyllobothrium stemmacephalum, commonly known as a broad tapeworm. Infections of marine mammals by Diphyllobothrium have been previously reported in the Northwestern Atlantic Ocean, but only to genus level. Infection by tapeworms may be rare in dolphins in South Carolina, but because this species is zoonotic, its presence indicates the potential for an emerging public health concern.

When traditional measures for material conditions are scarce or unreliable, body mass, height, and weight are complements to standard income and wealth measures. A persistent question in welfare studies is the 19th century’s 2nd and 3rd quarter’s stature diminution, a pattern known as the antebellum paradox. However, the question may not be well stated nor experienced equally by women and non-white male samples. The late 19th century’s political Granger, Greenback, and Populist movements may have affected farmer and non-farmer’s net nutrition. Despite 19th and early 20th century US political movements, farmers had greater BMIs, taller statures, and heavier weights than non-farmers. From the 1870s through 1890s, women’s body mass, height, and weight increased relative to men. Individuals of African or mixed European-African descent had heavier weights and greater BMIs than their taller, European-white counterparts, indicating that the traditional antebellum paradox needs to include women and non-European males and weight measures.

Moralising language is a powerful rhetorical tool for signaling political identity, persuading audiences, and mobilising voters. The valid and reliable classification of moral language is therefore a critical objective for political scientists. Recent advances in automated text analysis have introduced myriad new strategies for measuring morality in language, but have often produced conflicting, inconclusive findings. We investigate whether this diversity of moral content analyses might partially explain inconclusive findings, using a large corpus of political manifestos in four different languages (N=810 manifestos). Our results show that, despite starting from the same framework of Moral Foundations Theory (MFT), different instruments and underlying methodologies lead to remarkably different results for extracting moral foundations. Reproducing a previous study on political parties’ ideology and their use of moral foundations, we find that different measurements can lead to opposite effect directions. We discuss the relevance of our findings for research at the intersection of politics and moral rhetoric using automated text analysis.

While individuals are expected to perceive similarly identical quantities, regardless of the used units (e.g., 1 ton or 1000 kg), several scholars suggest that consumers over-infer quantities when they are presented in bigger and phonetically longer numbers. In two experimental studies, we examine this numerosity bias in the context of household food waste. Unlike previous scholars, manipulating numerosity revealed no effect: perceptions of food waste volume and likelihood to reduce it are not influenced by the used numeric value (2500 g vs. 2.5 kg; Study 1) nor the number of syllables (two kilos eight hundred seventy-five grams vs. three kilograms; Study 2).

With trade and the environment becoming increasingly interconnected, environmental impact assessments (EIAs) of trade negotiations help to integrate environmental considerations into trade-related treaty making by evaluating potential risks and opportunities, addressing public concerns, and facilitating the introduction of response measures. Despite international efforts, such ‘trade EIAs’ have not yet been universally adopted. At the domestic level, the United States, Canada, and the European Union have pioneered the use of EIAs through their institutionalized procedures for over 20 years. This article examines and compares the relevant practices of these three jurisdictions to identify major patterns and to discuss the pros and cons of existing differences in this area. It argues that the time-tested experience of these jurisdictions could provide benchmarks for consideration in promoting the widespread implementation of trade EIAs through global and regional trade regimes.

We propose and present evidence for a conjectural global-local phenomenon concerning the p-rationality of height-zero characters. Specifically, if $\chi $ is a height-zero character of a finite group G and D is a defect group of the p-block of G containing $\chi $, then the p-rationality of $\chi $ can be captured inside the normalizer ${\mathbf {N}}_G(D)$.

We present and test a model of reciprocity in which people are more likely to repay good treatment to the extent they judge it as motivated by true caring rather than tactical self-interest. The model’s key contributions stem from how it handles ambiguously motivated behavior. It allows people to maintain divergent hypotheses: They can view behavior as driven by caring, self-interest, or a mix thereof. In contrast, previous analyses resolve rather than maintain ambiguity. They treat caring and self-interest as mutually exclusive hypotheses, and require that people commit to one and dismiss the other. By more realistically handling ambiguity, our model yields three benefits. First, it accommodates intuitive patterns of play that existing analyses do not and which we experimentally corroborate. These patterns reflect intermediate inclinations to reciprocate ambiguously motivated positive behavior. Second, it challenges conventional interpretations of long-studied phenomena, including unraveling in finitely iterated prisoners’ dilemmas, substantial offers in ultimatum games, and gift exchange. Third, it highlights how diversity in perceptions – the same action can appear generous to one person and miserly to another – is empirically consequential. Under conventional interpretations and without accounting for diverse perceptions, the aforementioned phenomena have been viewed as inconsistent with a taste for repaying good treatment. Our model shows that they are entirely consistent with a nuanced form of this taste: a desire to repay good treatment that seems to largely reflect genuine caring.

This longitudinal study investigates the changes in bilingual oral language proficiency and home language and literacy practices of young Chinese American and Mexican American dual language learners (DLLs) before and during the COVID-19 pandemic. Given that DLLs represent a significant portion of young children in the U.S., often facing socioeconomic challenges, understanding their language development is crucial. The pandemic’s considerable impact on the educational trajectories of low-income immigrant communities is of particular concern. The sample comprised 132 DLLs (41 Mexican Americans and 91 Chinese Americans) from low-income immigrant families. Data on oral language proficiency in English and the home language and home literacy practices were collected before the pandemic and again 1.5 years later. Despite school closures, both groups showed improved oral language proficiency and shifts in home literacy practices over time. This study reveals distinct relationships between home literacy practices and oral language proficiency in the two immigrant groups.

Let k be a field finitely generated over its prime subfield. We prove that the quotient of the Brauer group of a product of varieties over k by the sum of the images of the Brauer groups of factors has finite exponent. The bulk of the proof concerns p-primary torsion in characteristic p. Our approach gives a more direct proof of the boundedness of the p-primary torsion of the Brauer group of an abelian variety, as recently proved by D’Addezio. We show that the transcendental Brauer group of a Kummer surface over k has finite exponent but can be infinite when k is an infinite field of positive characteristic. This answers a question of Zarhin and the author.

Ireland has a long-standing voluntary private health insurance market (PHI) which is regulated to meet the public policy objective of achieving risk solidarity to promote affordability of PHI. Under the regulations underpinning the market, many features are common to those of universal mandatory health insurance markets, that have wider equity objectives of ensuring universal equitable access to care for everyone. The market acts a complete/partial alternative to the public health system, and has been criticised for leading to a two-tier system with consequent implications for equity. To improve equity, these criticisms led to the adoption of a new public health reform plan, called Sláintecare, which seeks to build towards equal access to services based on patient need and not their ability to pay. Given this context, this paper re-examines how might the current voluntary health insurance system be adapted to meet the central Sláintecare objective of increasing health coverage on an equitable basis. It does so by considering to what extent does Ireland meet the preconditions for equity and efficiency under the Enthoven managed competition model. It provides a roadmap for the use of health insurance as a tool for bring this equity.

The increasing destruction of cultural heritage in conflict zones has exposed the shortcomings of current crisis response frameworks. Traditional, state-led mechanisms have struggled to address the complexities and rapid developments of modern warfare, leading to the emergence of more flexible, decentralized approaches. In this context, civil society organizations (CSOs) have emerged as key actors, stepping in to address the shortcomings of national governments and international heritage institutions. This article explores the evolving role of CSOs in emergency cultural heritage protection, focusing on Heritage for Peace (H4P) and its interventions in Syria, Sudan, and Gaza. Through case study analysis, this research examines the logistical, ethical, and operational challenges faced by H4P, and presents a model of its strategic interventions in emergency contexts. This model illustrates the opportunities and constraints inherent in crisis environments, including mobility and safety risks, alongside structural challenges in cultural heritage protection, such as limited funding and short-term project cycles that hinder sustainability. The research advocates placing the local population at the center of emergency strategies, strengthening local partnerships, implementing proactive preparedness measures, and strengthening international cooperation mechanisms.
