Formally, state parties are equal in all United Nations negotiations. In theory, every state, regardless of its size, economic or political power, has the same opportunities and rights to participate. Nevertheless, United Nations negotiations, such as those on climate, are often considered highly unequal in practice. Many states struggle to meaningfully engage in complex and highly technical multilateral negotiations, including because their delegations are smaller. Here we examine delegation size in United Nations climate negotiations through a procedural justice lens. Starting from normative principles of procedural justice, we argue that equitable negotiations demand the capability of all parties to send a sufficient number of delegates – around 15. Using descriptive analysis of data on delegation sizes of recent Conferences of the Parties, we then highlight that many parties in practice send smaller delegations. Based on these results, we suggest two routes for making climate negotiations more equitable: (i) providing additional resources to poor states to increase their delegation size; and (ii) trimming the overall negotiation agenda to lower the sufficiency threshold.

What is the point of a nuclear umbrella? Conventional wisdom suggests that explicit nuclear security guarantees provide junior allies with credible security, facilitating regional stability and nuclear non-proliferation. Yet this is not the only possible reason to maintain a nuclear umbrella. Reassessing the history and politics of nuclear alignment through a case study of the US–Norway alliance, I find that nuclear umbrellas have endured, and can do so, in cases where both the security patron and client believe the arrangement to lack military credibility.

France and Central European states have long been incarnating opposite sides of the European debates on how, where, and with (or against) whom to build the continent’s security. As this forum contribution will show, however, the major exogenous shock of the 2022 Russia-Ukraine war has altered this state of affairs. Deep-seated changes in France’s policies towards Russia and the Eastern neighbourhood, and Central European states’ greater (though relative) opening towards self-standing European security initiatives, have made their strategic outlooks more convergent than ever. Studying their variegated geopolitical visions, their evolutions, and the imaginaries that underpin them, reveal particularly fruitful to explore the realm of the possible when it comes to re-organising European security.

How old is war? Is it a deep-seated propensity in the human species or is it a recent cultural invention? This article investigates the archaeological evidence for prehistoric war across world regions by probing two competing hypotheses. The “deep roots” thesis asserts that war is an evolved adaptation that humans inherited from their common ancestor with chimpanzees, from which they split around seven million years ago, and that persisted throughout prehistory, encompassing both nomadic and sedentary hunter-gatherer societies. In contrast, the “shallow roots” viewpoint posits that peaceful intergroup relations are ancestral in humans, suggesting that war emerged only recently with the development of sedentary, hierarchical, and densely populated societies, prompted by the agricultural revolution ~ 12,000–10,000 years ago. To ascertain which position is best supported by the available empirical evidence, this article reviews the prehistoric archaeological record for both interpersonal and intergroup conflict across world regions, following an approximate chronological sequence from the emergence of humans in Africa to their dispersal out of Africa in the Near East, Europe, Australia, Northeast Asia, and the Americas. This worldwide analysis of the archaeological record lends partial support to both positions, but neither the “deep roots” nor the “shallow roots” argument is fully vindicated. Intergroup relations among prehistoric hunter-gatherers were marked neither by relentless war nor by unceasingly peaceful interactions. What emerges from the archaeological record is that, while lethal violence has deep roots in the Homo lineage, prehistoric group interactions—ranging from peaceful cooperation to conflict—exhibited considerable plasticity and variability, both over time and across world regions, which constitutes the true evolutionary puzzle.

This study examines the health and care itineraries in the Yvopey Renda indigenous community of the Western Guaraní people, within the framework of the Mutual Hospital Aid (AMH) system in Filadelfia, Paraguay. The research focuses on the care experience at the Filadelfia Indigenous Clinic and explores how the AMH insurance is implemented, its impacts on indigenous medical care, and how the lack of this insurance affects those without access. Through a qualitative methodological approach with an ethnographic perspective, participant observations and semi-structured interviews were conducted. The results reveal that self-care is the first option for ailments, followed by the AMH system for those with insurance. Limitations in access and care were identified, including lack of coverage for most community members, limited attention at the clinic, and restricted hours. The study also highlights the tension between the AMH's biomedical approach and traditional indigenous health practices, evidencing an asymmetrical relationship that affects the cultural identity and autonomy of indigenous people. It concludes that, despite criticisms, the AMH system represents a privileged service compared to the lack of access to quality public health services. The work underscores the need for a public health system specific to each indigenous community, with a comprehensive approach that respects and adapts to their traditional cultures.

Despite being the most susceptible to psychopathological consequences, bereaved cancer spouses remain a vastly understudied group. Addressing this gap, a dedicated French research team comprising clinical psychologists, philosophers, and physicians is conducting an ongoing study focused on the emotional and affective complexities experienced by bereaved spouses after the loss of a loved one due to oncological diseases within the realm of palliative care and Continuous Deep Sedation until Death (CDSD). The preliminary data presented below concern the analysis of nine semi-directed interviews analyzed using ALCESTE software, a tool for statistical analysis of textual data based on word co-occurrences. Analysis and comparison of the thematic categories that emerged showed that social support, deep loneliness, and the preservation of memories emerged as central elements of the marital bereavement experience. In addition, the study highlights the critical role of comprehensive palliative care in France and the delicate nature of sedation experiences, revealing intense emotions such as helplessness and anger. Clear communication and active family participation in end-of-life decisions emerged as crucial factors in alleviating the grieving process in spouses. These findings provide valuable insights for healthcare professionals and counselors and underscore the critical need for further research focused on sedation.

Background Hospital falls continue to be a persistent global issue with serious harmful consequences for patients and health services. Many clinical practice guidelines now exist for hospital falls, and there is a need to appraise recommendations. Method A systematic review and critical appraisal of the global literature was conducted, compliant with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Web of Science, Embase, CINAHL, MEDLINE, Epistemonikos, Infobase of Clinical Practice Guidelines, Cochrane CENTRAL and PEDro databases were searched from 1 January 1993 to 1 February 2024. The quality of guidelines was assessed by two independent reviewers using Appraisal of Guidelines for Research and Evaluation Global Rating Scale and Appraisal of Guidelines of Research and Evaluation Recommendation Excellence (AGREE-REX). Certainty of findings was rated using Grading of Recommendations Assessment, Development and Evaluation Confidence in Evidence from Reviews of Qualitative Research. Data were analysed using thematic synthesis. Results 2404 records were screened, 77 assessed for eligibility, and 20 hospital falls guidelines were included. Ten had high AGREE-REX quality scores. Key analytic themes were as follows: (i) there was mixed support for falls risk screening at hospital admission, but scored screening tools were no longer recommended; (ii) comprehensive falls assessment was recommended for older or frail patients; (iii) single and multifactorial falls interventions were consistently recommended; (iv) a large gap existed in patient engagement in guideline development and implementation; (v) barriers to implementation included ambiguities in how staff and patient falls education should be conducted, how delirium and dementia are managed to prevent falls, and documentation of hospital falls. Conclusion Evidence-based hospital falls guidelines are now available, yet systematic implementation across the hospital sector is more limited. There is a need to ensure an integrated and consistent approach to evidence-based falls prevention for a diverse range of hospital patients.

Doryopteris raddiana (Presl) Fée, a traditional contraceptive in Mbya culture, lacks scientific scrutiny regarding its chemical composition and contraceptive efficacy. Employing X-ray fluorescence, Fourier-transform infrared spectroscopy, and thermal analysis, we explored the plant's organs. Multielemental analysis excluded toxic elements. Key phytoconstituents identified by gas chromatography-mass spectrometry in the extracts obtained through infusion were glycerine, 1,3-dimethyl propane, and catechol in leaves; glycerine, cis-13-octadecenoic acid methyl ester, and 2-deoxy-D-erythro-pen-tose in stems and roots. Among these chemicals, glycerine emerged as the sole constituent with contraceptive potential, particularly intravaginally. Extract activity tests conducted on ram spermatozoa exhibited a reduction in the percentage of rapid spermatozoa but no significant impact on total motility, progressive motility, or viability. The reported data would only weakly support the advocated contraceptive action of this fern upon vaginal application, not through the oral administration of its decoction.

In 1946, one year after the atomic bombings of Japan, Palestinian thinker ʿAli Rashid Shaʿath (1908–1967) published a book entitled Min al-binsilin ila al-qunbula al-zarriya (From Penicillin to the Atomic Bomb). An accessible work of popular science, it contains highly optimistic reflections on the future and predicts the following two events as a result of nuclear technology and energy: a workers’ utopia and world peace. This article situates Shaʿath’s voice within a global conversation about the atomic age, which led to new forms of futuristic and utopian thinking. Analyzing broader Arab articulations of the future through Shaʿath’s writing, we critically engage his embrace of atomic technology as a mode of emancipation.

This study explores the phytochemical composition of leaf extracts from Handroanthus impetiginosus (Mart.) Mattos and Luehea divaricata Mart., used in a contraceptive decoction by Mbya-Guarani women. The phytocompounds were identified by gas chro­matography-mass spectrometry, while Fourier-transform infrared spectroscopy, multi-elemental, and thermal analyses were used to characterise plant biomass. Notably, no phytoconstituent supporting the efficacy of these extracts as female contraceptives was found, except for a small amount (0.3%) of sitosterol. Conversely, L. divaricata leaves contained compounds like 1,3-dihydroxyacetone dimer, N-methyl-N-nitroso-2-propanamine, 2-methoxy-N-(2-methoxyethyl)-N-methyl-ethanamine, and 1,3,5-triazine-2,4,6-triamine, potentially exerting cytotoxic, genotoxic, and toxicogenomic effects. Due to the absence of scientific support for the claimed contraceptive efficacy and the presence of safety concerns, we propose an alternative valorisation pathway centred on the presence of phytochemicals exhibiting antimicrobial activity. This proposition is substantiated by their considerable in vitro efficacy against Botrytis cinerea.

In 1990, three years after Andy Warhol’s death and one year after the fall of the Berlin Wall, the Museum of Modern Art (MoMA) organized the first one-man show of this pop artist in Eastern Europe. The Prints of Andy Warhol, although never shown at the MoMA in New York, traveled to the Fondation Cartier pour l’Art Contemporain in Jouy-en-Josas, France, the Národní Galerie in Prague, Czechoslovakia, the Staatliche Kunstsammlung in Dresden, the GDR, the Mücsarnok in Budapest, Hungary, and the Muzeum Narodowe in Warsaw, Poland. The current paper analyzes the cultural–political context of The Prints of Andy Warhol. It first discusses the place of both American pop art and Eastern Europe in MoMA’s International Program (IP) and then explores the organizational challenges, art historical contents, and public reception of the exhibition. The paper concludes by examining the broader impact of The Prints of Andy Warhol on both the growing awareness of American pop art in Eastern Europe and MoMA’s cultural diplomacy in this region after the fall of the Iron Curtain.

The value co-destruction process has been heavily studied in recent years. However, most studies have focused on the value of co-destruction's emotional and behavioral consequences without considering its psychological impact on consumer behavior. This study bridges this research gap by examining consumer alienation as a fundamental psychological state that underpins the value co-destruction process. Its primary objective is to delve into the significance of alienation within retail banking, uncovering its underlying causes and consequences. Furthermore, the study examines how the external locus of control affects the behavior of alienated consumers. The data were collected from 211 French retail bank users. Structural Equation Modeling was used to test the hypotheses. The study showed that consumers’ discontent, perceived differential treatment, and financial distress lead to value destruction and influence consumer alienation toward retail banking service providers. A high level of alienation leads to payment delinquency, negative WOM, and switching intentions to internet-only banks. The external locus of control moderates these relationships. By identifying the antecedents and consequences of consumer alienation in retail banking, this study provides practical advice to retail banking providers on retroactively identifying alienated consumers. This study provides ideas on restoring lost value, retaining customers, and preventing them from switching to internet-only banks. Our research enriches the Service-Dominant Logic theory by exploring the role of consumer alienation on the value co-destruction process. It enhances the understanding of consumer alienation in retail banking.

Sudden rises in migration across the borders of the Global North have persistently attracted substantial media attention and fueled hostility toward “irregular migrants” and “bogus refugees.” While existing qualitative studies have extensively criticized the migrant-refugee distinction, we offer unique quantitative evidence of how migration numbers and labels construct impressions of increased irregular migration while in fact creating “fake illegals.” We conduct a two-stage mixed-method analysis, demonstrating first that data on “irregular/illegal border crossings” (IBCs) published by Frontex have become an authoritative source of information on migration flows cited in a corpus of mainstream news media articles. We then posit that, while persecutions and violence in countries of origin may trigger migration, it is policies in destination states that determine who “is” and “isn’t” a refugee. In turn, we develop a novel method to divide IBCs into those who would likely obtain asylum in 31 European destination states (“likely refugees”) and those who would not (“likely irregular migrants”) across time given asylum acceptance rates by nationality. We estimate that between 2009 and 2021 most border crossers labeled as “irregular/illegal” (55.4%) were actually “likely refugees,” a proportion we estimate to be 75.5% at the peak of arrivals in 2015. Thus, we find that sudden and large increases in border crossings concentrated in space likely concern forced rather than irregular migrants. Altogether, our constructivist approach reveals how migration data and categories both influence and are influenced by securitized border policies and that, in this respect, borders start with numbers.

What if the Taliban, with military and technological capabilities far inferior to those of Western armies, had won the war through law? While the international coalition set up an inadequate and corrupt legal system, the Taliban set up hundreds of courts in the countryside: by insisting on due process, impartiality from the judges, and the enforcement of verdicts, this system of justice has established itself as one of the few sources of predictability in the daily lives of Afghans. ‘The Taliban court is for all people of Afghanistan but the government’s court is only for rich people’, said one resident of Wardak province. How did the Taliban gain the trust of the population? How did they manage to put themselves in a position to regulate social relations? And with what consequences for Afghan society? Based on long-term fieldwork in various provinces in Afghanistan, this investigation offers new perspectives on a country that was at war for over four decades and proposes an innovative reflection on the place of law in civil wars.

In recent years, there has been a growing interest in the international dimensions of populism, by now a major political phenomenon around the world. This interest, however, has been confined largely to the state level, especially the influence of populism on foreign policy. In this Forum, we argue that it is important for analysis to move beyond the state level and view populism as a concept and phenomenon of international relations (IR) rather than simply a factor of foreign policy. The Forum discusses implications of the rise of populism for IR theory, the role of international systemic change in the emergence of populism in national arenas, and the ways that regime type, state structure and institutions, ideational content, and the political strategies of populists condition the impact of populism on world politics. In this way, the Forum identifies specific directions for the study of populism in IR that scholars can follow in the future.

The United States, its Allies, and its partners can adapt to the demands of the emerging strategic context by learning lessons from the tumultuous past five years, i.e. the COVID pandemic and related challenges across Western society, deterioration of relations between China and the West, and Russia’s illegal annexation and (re)-invasion of Ukraine. On the one hand, the bridging of alliances should reinforce existing frameworks by widening areas of cooperation across sectors, deepening collaboration in areas like technology transfer and industry

In an age of innovation and digitalisation, critical thinking has become one of the most valued skills in the labour market. This paper shows how teachers can empower students to develop their students' critical thinking. After recalling why critical thinking matters for democracy and the economy, a definition of critical thinking is outlined. Next, a demonstration is given of how the concept critical thinking can be translated and simplified using teacher‐friendly rubrics that can support the design or redesign of lesson plans, teacher observations and formative assessment—as well as standardised assessments. In conclusion, the paper argues that critical thinking should be mainstreamed in all subjects in school curricula, and that it leads to deeper understanding of subject matter content.
