Almost 50 years have passed since Sartori introduced to the world one of the most famous innovations in the history of political science: a new party systems typology. Despite many criticisms and refinements since then, Sartori's typology still constitutes, as stated by Peter Mair in 1990, “the most effective and exhaustive framework within which to contrast the properties of different party systems”. In the current research note, and taking into consideration that previous typologies have not yet been that successful, we propose a new classification of party systems – which not only embeds the notion of polarization into the typology, but also allows us to populate the “polarized pluralist” type beyond Sartori’s “centre-based” (Italian) model – in Asia, a continent almost completely ignored by Sartori in his seminal work. Using an original dataset that includes the most important characteristics of party systems in the region and building on Sartori's original conceptualization, we examine to what extent party systems in Asian democracies, both contemporary (Bhutan, East Timor, India, Indonesia, Japan, Malaysia, Mongolia, Nepal, Pakistan, Philippines, South Korea, Sri Lanka and Taiwan) and historical (Bangladesh 1991–2006, Kyrgyzstan 2010–2020, Myanmar 2015–2020 and Thailand 1992–2013), have changed. Our discussion of a new party system typology is particularly relevant and important to Asia, as its many new democracies still need to shift from plurality electoral rules adopted during the early post-independence periods to more mature, power-dispersing political institutions that accommodate their rich ethnic and religious diversity, as it happened in Europe after the World Wars.

Large-scale field investigation in the Eastern Tianshan Mountains of Xinjiang identified 108 Palaeolithic/microlithic surface findspots. Pulei Cave reveals the first well-preserved spelean sediment record containing Upper Palaeolithic cultural remains in eastern Xinjiang, dating from c. 45–43 ka BP.

This article challenges the OECD’s dominant downstream-centric framework on plastic pollution by drawing on long-term ethnographic fieldwork in India, Indonesia and the Philippines. While OECD policies emphasize mismanaged waste and littering in low- and middle-income countries as primary causes of plastic leakage, the authors argue this perspective obscures the structural role of upstream plastic production, driven largely by petrochemical interests in the Global North. Through field data, the article reveals how “leaky” infrastructures – such as incineration plants in India, public–private waste partnerships in Indonesia and grassroots upcycling in the Philippines – fail to contain plastic waste, often exacerbating pollution and exposing communities to toxic emissions and microplastics. The study introduces a conceptual framework of “material and structural leakiness,” emphasizing how plastics and the infrastructures designed to manage them are inherently porous. It critiques the notion of shared responsibility, highlighting how it disproportionately burdens marginalized communities. The authors call for a paradigm shift away from recycling and clean-up as core solutions, advocating instead for upstream interventions like production caps and chemical regulation. The article underscores that without legally binding global commitments to reduce virgin plastic production, the toxic burden of plastic pollution will continue to fall on the most vulnerable populations.

Collaboration is both a process and an outcome. Collaboration is based on the idea that interactions between participants with a common goal, working together as partnerships and sharing resources, can solve complex or “wicked” problems that are not possible to solve in isolation. Collaboration may be simple, occurring between individuals, or more complex interorganizational arrangements across sectors, with the life cycle and size of the collaboration determined by the issue at hand. HTA collaborations may involve a wide range of stakeholders, including HTA agencies at the national, regional, or global level, academia, government (including regulatory authorities), industry, clinicians, providers, and patient organizations. Regardless of the number or type of participants, collaborations need a shared understanding of the common goal, an agreement on aims, and a commitment to shared solutions.

Industry and agency members of the Health Technology Assessment International (HTAi) Asia Policy Forum (APF) met in Seoul, South Korea, in November 2024 for open discussions on how to facilitate and improve the collaborative process between all stakeholders in the health system, including government, HTA agencies, industry, academia, clinicians, as well as patients. Over the three days, these discussions identified some of the risks and obstacles to collaboration in the region, how to develop and use collaboration better, as well as articulating the value and benefits of collaboration both in the region and globally.

Following the recent report of strongyloidiasis caused by Strongyloides fuelleborni within a semi-captive colony of baboons in a UK safari park, we investigated the genetic relationships of this isolate with other Strongyloides isolates across the world. Whole-genome sequencing data were generated with later phylogenetic analysis of mitochondrial (mt) cytochrome oxidase subunit 1 (cox1) and nuclear ribosomal 18S sequences against 300 published Strongyloides reference genotypes. The putative African origin of the UK S. fuelleborni was confirmed and full-length mt genome sequences were assembled to facilitate a more detailed phylogenetic analysis of 14 mt coding regions against all available Strongyloides species. Our analyses demonstrated that the UK isolate represented a novel African lineage not previously described. Additional complete mt genomes were assembled for several individual UK safari park worms to reveal a slightly altered mt genome gene arrangement, allowing clear separation from Asian S. fuelleborni. Furthermore, these UK worms possessed expanded intergenic regions of unknown function that increase their mt genome size to approximately 24 kilobases (kb) as compared with some 16 kb for Asian S. fuelleborni; this may have arisen from unique populational founder and genetic drift effects set within the peculiar mixed species baboon and drill ancestry of this semi-captive primate colony. A maximum likelihood phylogeny constructed from 14 mt coding regions also supported an evolutionary distinction between Asian and African S. fuelleborni.

Although there is a clear rise in academic interest in region formation, theoretical approaches to the topic vary greatly, stemming from geopolitical identifications of objective regional boundaries, through functionalist ideas of regional linkages, to post-structuralist ideas about fluid regional belonging. This article provides a typology of region formation approaches, based on the ontological assumptions of its authors. The typology is based on two main debates within contemporary international relations ontology: regarding the basic components of reality (material vs. ideational) and regarding the status of theories (transfactual vs. phenomenalist). The presented matrix provides an ideal-typical position for each of these four iterations and illustrates its viability in the case of region formation literature on the Asia-Pacific. Doing so, the text contributes to (meta) theoretical discussions of how regions are formed while at the same time illustrating the often-overlooked stories of region formation.

In 2022, the Centre for Global South Asia (CGSA) at Royal Holloway University of London developed a small research project entitled ‘Exhibit Asia’. The aim was to explore the use of exhibitions in nation-making in postcolonial South and East Asia in contrast to the scholarly preoccupation with investigating the region’s history of museums and exhibitions primarily in a colonial context. Its academic outcomes were to be a conference and related publication; but we also wanted our research to be relevant to our students. The resulting intervention in the teaching and learning of history took the form of a curatorial fellowship for an international cohort of ten students from Taiwan, Japan, India, Pakistan and the UK, leading to a co-curated online exhibition. The first section of this article sets out the development, design and delivery of the fellowship and discusses the viability and relevance of such projects. The subsequent three sections are co-authored by several of the participating students. They outline their methods, reflections and learnings; share their insights on the role of exhibitions in perceptions of Asia in the UK today; and analyse responses to ‘Tea and Tigers’, the online exhibition that was the outcome of the fellowship.

Eight Acheulean sites are located in an under-researched ecological setting within the hilly terrain of the Upper Son Valley, India. A total of 1348 Acheulean artefacts have been identified across these sites, primarily preserved in high-energy depositional contexts, providing insights into the Pleistocene environment of hominin occupation and available lithic technology.
