The Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6) resulted in many ice-sheet simulations from multiple ice-sheet models. To date, no model weighting studies have analyzed or quantified the model performance, possible duplication of the ISMIP6 ice-sheet models and the effect on mass loss projections. In this study, we adopt a model weighting scheme for the ISMIP6-Greenland that accounts for both model performance compared to observation and model similarity due to possible duplication. We choose ice velocity and thickness for the measurement of model performance, and we use all suitable variables to compute similarity indexes. We update the sea level rise contribution from ISMIP6-Greenland by the end of this century with the weights, and we find that, although the multi-model mean is not considerably shifted (mostly within $ \pm 1{\text{cm}}$), the model spreads are reduced by 10–30% after applying the model weights. The magnitude of reduction varies largely among experiments and types of model weights applied. In general, we find that the model weighting scheme is skillful in producing model weights that effectively and reasonably quantify the model performance and inter-dependency, which can potentially benefit the future phase of the Ice Sheet Model Intercomparison Project, i.e. ISMIP7.
Conceptualizations of surge capacity are gaining traction in disaster preparedness and response, particularly in the context of critical and acute care during the pandemic as well as other disaster contexts. In most applications, the surge capacity domains describe the four types of assets required to ensure that surges in demand are addressed. Despite increasing interest and conceptual application, these constructs are yet to be considered or explored in relation to the profound resource scarcity and complex contexts of humanitarian health responses.
Objectives:
The aim of this research is to explore surge capacity domain constructs in the novel context of scarce health resource allocation in humanitarian health care response settings.
Methods:
This research was conducted according to an exploratory qualitative design. Clinicians and managers with relevant experiences were purposively recruited to include broad perspectives across humanitarian responses and clinical specialties. Interview transcripts were analyzed using a latent deductive pattern approach, using a deductive code book consisting of existing surge capacity domains to explore surge capacity constructs. Analysis of coded data for cross-cutting themes drove identification of new findings regarding surge capacity in the context of humanitarian health responses.
Results:
Seventeen participants completed semi-structured interviews. In addition to demonstrating the relevance of existing surge capacity domains (staff, stuff, space, and systems; 4Ss), four new themes emerged: (1) sponsorship; (2) suitability; (3) security; and (4) supply. These four themes informed the conceptualization of surge capacity dimensions which must be satisfied for an asset to render a positive impact with relevance to all four surge capacity domains (4S2 - cumulative 4S domains and the new dimensions).
Conclusions:
Although existing surge capacity domains have proven relevant to humanitarian health care response settings, this research produced a revised conceptualization of surge capacity constructs specific to this context. The identification of four surge capacity dimensions supported the conception and development of the Scarce Health Resource Allocation in Humanitarian Response Settings (SHARE-HRS) 4S2 model of surge capacity, thus offering a potential new tool to support humanitarian health response planning and evaluation.

Advancing the emerging field of comparative climate governance and policymaking, this book explores national loss and damage policymaking through seven empirically grounded studies of loss and damage governance across vulnerable countries in the Global South. The introductory chapter sets the scene by presenting the key themes, research questions, and contributions of the book. Following an introduction to the concept of loss and damage from climate change impacts and its emergence at the international level, the chapter argues for a political science of loss and damage that is sensitive to the “national turn” in research on loss and damage governance. The chapter then presents the seven country case studies featured in the book including Small Island Developing States, least developed countries, and emerging economies: Tuvalu, Antigua and Barbuda, The Bahamas, Ethiopia, Bangladesh, Peru, and Chile. The case studies show variation in the way countries engage with loss and damage, highlighting the importance of national contexts in understanding the success and/or failure of policymaking. The chapter concludes with a summary of key themes and findings emerging from the case studies and discusses ways in which they advance our understanding of climate policy.
Digital and environmental policies are increasingly seen as complementary, both domestically and internationally. In international trade policy, digital and environmental issues have been and continue to be discussed in multilateral negotiations at the World Trade Organisation and in plurilateral negotiations on preferential trade agreements (PTAs). This chapter takes a closer look at the design and impact of digital and environmental provisions in Latin American PTAs. It begins with a brief comparative overview of domestic digital and environmental policies in Latin America, followed by a discussion of the design features of Latin American PTAs. The final section provides an empirical analysis of the impact of these design features on trade. While there is considerable heterogeneity across Latin American countries and PTAs, the analysis suggests a positive relationship between digital and environmental policies. Latin American countries with more ambitious domestic digital policies tend to have more ambitious domestic environmental policies, and vice versa. Similarly, Latin American countries with a broader coverage of digital issues in their PTAs also tend to cover a broader range of environmental issues in their PTAs, and vice versa. The empirical results suggest that the presence and design of digital and environmental provisions in Latin American PTAs have no statistically significant impact on the volume and composition of imports. For exports, the analysis suggests that digital provisions in PTAs tend to increase flows, while the opposite is true for environmental provisions.
By way of recognizing the considerable scholarship that makes the Balkans the best-studied and best-understood sprachbund (contact area), and by way of establishing a baseline of knowledge about the Balkans from a linguistic perspective, Balkan linguistics as a field is surveyed here from an historical perspective, with key scholars and their important works highlighted. Attention is given to pre-modern treatments and to the early modern era of Balkan linguistics, with a particular focus on a watershed moment for the field, the publication of Kristian Sandfeld’s Linguistique Balkanique (1930) and the very rich work done in the modern era after Sandfeld. Meta-questions such as which groups to include in discussions of Balkan linguistics and the relation of the Balkans to (Western) Europe are addressed as well.
Important developments are currently affecting the global trading system. We witness increasing calls for protectionism and a surge in populism in some major economies, while other trading nations continue to liberalise trade, driven by the dynamics of global value chains (GVCs). Even committed trading nations have shown an increased willingness to use industrial policies and have elevated the pursuit of geopolitical concerns through trade. On top of this, calls have increased to tackle the climate crisis through trade policy instruments. In short, important shifts induced by politics and economics shape today’s trade policies.
This article describes the Implementation Science (IS) Scholars Program at the University of Arkansas for Medical Sciences (UAMS). The program’s goal is to translate knowledge, approaches, and methods from IS to front-line clinicians in an academic medical center, thereby supporting its goals as a learning health system and promoting a dynamic workforce of IS-informed change leaders. Initiated in 2020, the program is relatively unique in that it attempts to translate concepts and knowledge from IS to clinicians to improve their skills as implementers and change agents. The program is supported by the Translational Research Institute, the UAMS’ awardee of the Clinical and Translational Science Award Program. The two-year program provides 20% salary coverage, bespoke didactics, and close mentoring on a Scholar-initiated project to improve care in their clinical context. The program has trained four cohorts of Scholars over the program’s initial five years. We describe the program, our evaluation of it thus far, and future plans. The program has contributed to numerous healthcare improvements and served as a gateway to future implementation and other research activities among some Scholars.
This article reappraises the early intellectual formation of the medieval “lex mercatoria” thesis: the idea that the international merchants of medieval Europe (or perhaps beyond) enjoyed a universal, autonomous, and customary body of commercial law created and administered by themselves. The debate over its existence, raging for at least 120 years, shows no signs of slowing, in part because the idea is of undoubted usefulness to both proponents (so-called “mercatorists”) and critics. The article offers a new account of the origins of this idea and looks to disaggregate different mercatorist conceptions. Revising the conventional genealogy that traces the theory through the work of Berthold Goldman to the nineteenth-century German scholar Levin Goldschmidt, who is much misunderstood in Anglophone scholarship, it argues that the idea’s powerful re-emergence in the second half of the twentieth century was mediated through two distinct channels, one centred around the British-German jurist Clive Schmitthoff and the other around the British historian William Mitchell. The latter yoked Goldschmidt’s emphasis on the medieval merchant class as a source of legal innovation to a thoroughly Anglophone concept: the “law merchant”. Critics, however, have engaged primarily with Schmitthoff’s conception, whose “strong” mercatorist argument was not only unusually forthright but reoriented the debate to focus on commercial law’s supposed autonomy from the law of territorial states, an even less plausible proposition in historical terms.
Chapter 6 treats Balkan convergence involving morphology and morphosyntax more generally, focusing particularly on inflectional morphology. Attention is given to categories and to forms, as well as the special, and often nuanced, functions and semantic range of particular items. Convergence involving nouns and noun phrases is documented, with regard to case, deixis, definiteness, gender, number, and adjectival modification. Particular attention is given to the development of analytic structures. Regarding verbs and verb phrases, convergence is discussed in the categories of tense, aspect, mood, evidential marking, voice, and valency.
In this first full chapter readers will find a general survey of those aspects of Balkan geopolitical, cultural, and linguistic history that are most relevant for the present study, including the Balkans in relation to the Ottoman Empire. We locate the Balkans geographically, describing its physical characteristics and discussing the controversy over where its northern limits are to be located. Various other extralinguistic factors are discussed that are relevant for the linguistic situation. Most importantly, the languages of the Balkans are introduced as to their genealogical affiliation, their historical attestation, their documentation, their pertinent representation in scholarly literature, their dialectology, their social setting, and related matters, including associated writing systems. For the sake of completeness, all languages found in the Balkans, from ancient to early modern, are given some attention, creating a comprehensive account of the geographically determined languages of the Balkans; ultimately, though, the focus is narrowed to the Balkan languages, i.e. those languages in the region that significantly (or in any attested fashion) display the morphosyntactic and other convergence phenomena that are central to the concept of a contact area, i.e. to a sprachbund.
This final chapter, Chapter 8, offers a summation of the major trends of development seen in the preceding chapters, and addresses the key question of causation, looking at the forces that led to the convergence seen across the Balkan languages. Multilateral, multigenerational, mutual, multilingualism (our “four-M” model) is argued to be the leading element in the convergence, with particular focus on the speaker-plus-dialect approach. An assessment of the construct of “sprachbund” is offered, and it is argued that the Balkan sprachbund is not a remnant of an historical state that no longer exists, but rather is very much alive, albeit in more limited contexts than in the past.
Peripartum depression (PPD) is a prevalent mental health disorder in the peripartum period. However, a recent systematic review of clinical guidelines relating to PPD has revealed a significant inconsistency in recommendations.
Aims
This study aimed to collect up-to-date evidence on the effectiveness of interventions and provide recommendations for prevention, screening and treating PPD.
Method
A series of umbrella reviews on the effectiveness of PPD prevention, screening and treatment interventions was conducted. A search was performed in five databases from 2010 until 2023. The guidelines were developed according to the GRADE framework and AGREE II Checklist recommendations. Public stakeholder review was included.
Results
One hundred and forty-five systematic reviews were included in the final analysis and used to form the guidelines. Forty-four recommendations were developed, including recommendations for prevention, screening and treatment. Psychological and psychosocial interventions are strongly recommended for preventing PPD in women with no symptoms and women at risk. Screening programmes for depression are strongly recommended during pregnancy and postpartum. Cognitive–behavioural therapy is strongly recommended for PPD treatment for mild to severe depression. Antidepressant medication is strongly recommended for treating severe depression in pregnancy. Electroconvulsive therapy is strongly recommended for therapy-resistant and life-threatening severe depression during pregnancy. Other recommendations are offered to healthcare professionals, stakeholders and researchers in managing PPD in different contexts.
Conclusion
Treatment recommendations should be implemented after carefully considering clinical severity, previous history, risk–benefit for mother and foetus/infant and women’s values and preferences. Implementation of evidence-based clinical practice guidelines within country-specific contexts should be facilitated.
