    Kulczycki, Emanuel; Gamboa, José Octavio Alonso; Beigel, Fernanda; Digiampietri, Luciano A.; Laakso, Mikael; Pölönen, Janne; Taşkın, Zehra; Cuartas, Gabriel Vélez

    Purpose This study investigates the diversity of national scholarly journal publishing ecosystems in seven countries across Europe and Latin America: Argentina, Brazil, Colombia, Finland, Mexico, Poland, and Türkiye. It challenges the common perception that global scholarly publishing is dominated by international commercial publishers by examining national publishing structures beyond English speaking contexts. Design/methodology/approach Using ISSN Centre data and national sources, we analyse journal-level publishing structures rather than article- or citation-level outputs. Publishers were categorized according to their institutional and organizational characteristics. The analysis focuses on active journals, defined as those with a recorded start year and no identified termination date. Journal coverage in Web of Science, Scopus, and OpenAlex was examined to assess how national publishing landscapes are represented in major bibliometric databases. Findings Educational institutions emerge as the primary publishers in most countries, representing more than 75 % of journals in Colombia and Brazil and more than 50 % in Mexico, Argentina, and Poland. Finland stands out, with scientific and professional associations leading journal publication at 62 %. Commercial publishers hold comparatively small shares, reaching their highest levels in Türkiye at 12.1 % and Poland at 8.2 %. In terms of database representation, OpenAlex indexes over half of the journals in most countries, whereas Web of Science (WoS) and Scopus cover only a small portion. Research limitations The study relies on ISSN and national datasets, which differ in completeness and standardization. Variations in national reporting practices and database indexing policies may influence coverage comparisons. As the analysis is based on currently active journals, historical trends reflect surviving journals only. Practical implications The results provide evidence for policymakers, database providers, and research evaluators to recognize the diversity of national publishing systems. They highlight the importance of improving data sources and analytical approaches to ensure more accurate assessment of scholarly communication outside heavily commercialized environments. Originality/value The study offers a comparative analysis of national journal publishing ecosystems across seven countries, revealing structural differences that challenge the assumption of a globally uniform publishing model. It underscores the need for bibliometric research frameworks that include and accurately represent national and regional publishing structures.

    Entrepreneurial ecosystems (EEs) are systems shaping innovation and sustainable development, yet limited evidence exists on the relative predictive contribution of their components to sustainable value creation. This study examines associations between six EE dimensions and environmental, social and economic value creation among 245 knowledge‐intensive ventures supported by the PIPE programme of the São Paulo Research Foundation (FAPESP), Brazil. Using cross‐sectional, self‐reported survey data, composite indices were constructed through the CRITIC method and analysed with machine‐learning models, Monte Carlo repeated holdout validation and SHapley Additive exPlanations (SHAP). Regression performance was modest, and classification performance was moderate. Within the selected predictors and this sample, cultural conditions showed the highest mean absolute SHAP importance across all outcomes, whereas the remaining dimensions varied. These results provide context‐bound predictive evidence, not causal inference or a universal hierarchy. The study contributes an interpretable framework for comparing ecosystem dimensions in a specific Brazilian regional and institutional setting.

    Between linkage and return: the engagement strategies of the Knowledge Brazil Program for the scientific diaspora(opens in a new tab)

    Cavasin, Mariana Luiza Castilho; Carneiro, Ana Maria

    Funded by CAPES

    In recent decades, countries of origin have increasingly sought to develop policies to engage with their scientific diaspora. These policy designs typically vary across models of repatriation, linkage, and circulation, aiming to strengthen national science, technology and innovation (STI) systems. This article analyses the design and early implementation of the Knowledge Brazil Program to identify the strategies prioritized by the Brazilian state in engaging with its scientific diaspora. The study is based on document analysis, program microdata, and media sources, including news reports and opinion articles from widely circulated outlets. The findings are synthesized through a SWOT analysis, identifying strengths in the program's design, which incorporates the three core components of diaspora engagement—repatriation, linkage, and circulation; weaknesses in the asymmetry between the program's axes, with a clear emphasis on repatriation; opportunities in the diaspora's willingness to contribute to the national STI system; and threats related to concerns regarding the absorption of researchers into academia after the program's completion.

    Disambiguating research entities remains a long-standing methodological problem in scientometric analyses, as inconsistencies and ambiguous metadata limit the interoperability of major bibliographic databases. While global systems such as OpenAlex provide extensive coverage, they often lack the granularity and accuracy provided by national-level research databases. This study proposes a large-scale methodology to enhance author and institutional disambiguation by integrating local (Lattes and CAPES) and global (OpenAlex) databases. The method combines shared Digital Object Identifiers with an adapted Levenshtein distance algorithm to handle variations in author and institutional names across multilingual research databases, achieving over 97% accuracy for authors and 64% for institutions. The proposed framework provides a scalable and replicable approach for entity disambiguation in tabular research databases. Beyond the Brazilian context, this integration strategy offers a globally applicable approach for harmonizing national research information systems with open scientometric infrastructures.

    The expansion of arid and dry ecosystems during the Miocene played a key role in the diversification of succulent plants; however, the relative contributions of biotic traits and environmental factors linked to aridity remain unclear. We investigate diversification in the cactus tribe Cereeae by integrating phylogenomic, biogeographic, and trait-based diversification analyses. We reconstructed a time-calibrated phylogeny and inferred ancestral ranges through biogeographic process-based modeling. We assessed diversification rate heterogeneity and evaluated the impacts of biotic traits and environmental variables using machine learning and trait-dependent diversification analyses. Our results indicate that Cereeae diverged in the late Miocene (∼9 Ma), with ancestral range spanning from the Central and Southern Andes to Espinhaço Mountain Range in Southeastern Brazil. Vicariance events, likely driven by marine transgressions and the assembly of the Cerrado savanna, promoted isolation of taxa across the Andes and Southeastern Brazil. Eastern Brazil was recolonized via jump dispersal during the Miocene-Pliocene transition. Diversification rates were strongly associated with rupicolous substrate preference and globose growth form, while environmental variables showed a negligible correlation with diversification. Our findings underscore the Southern Andes as a likely source of xerophytic lineages and highlight ecological specialization as the dominant driver of Cereeae radiation. This study demonstrates how integrative approaches can disentangle complex evolutionary processes, revealing that morphological innovation prevailed over environmental filtering in shaping the diversification of Cereeae in dry habitats.

    This study explores the funding, authorship patterns, and citation impact of articles funded by the Ministry of Education and Science of Ukraine (MESU), the National Academy of Sciences of Ukraine (NASU), and the National Research Foundation of Ukraine (NRFU). The analysis focuses on articles published in Scopus-indexed journals in 2020–2023. The study findings revealed that the share of articles funded by these agencies increased from 8.6% in 2020–2021 to 11.9% in 2022–2023. Foreign cofunding, international coauthorship, and foreign coaffiliations were consistently associated with higher citation impact. In 2022–2023, foreign coaffiliations had a positive effect on the citation impact of MESU-funded articles, with FNCI exceeding that of articles cofunded by MESU and foreign agencies. In 2020–2021, NASU-funded articles had only a modest advantage in citation impact over unfunded articles. In 2022–2023, this pattern changed, with unfunded articles slightly exceeding NASU-funded articles in overall citation impact. Among articles with foreign coaffiliations and international coauthorship, unfunded articles exhibited a citation advantage over NASU-funded articles, while the citation impact of articles with Ukrainian affiliations was broadly similar. These findings raise questions about the effectiveness of current research evaluation criteria and funding allocation mechanisms and underscore the need for evidence-based reform of Ukraine’s research funding system.

    Funded by FAPESP, UNICAMP

    The international mobility of highly qualified scientists has drawn increasing attention from researchers and policymakers, especially regarding scientific diaspora networks. These networks enable exchange of knowledge and technology and academic collaboration, benefiting sending and receiving countries. Bibliometric methods have been widely used to track academic mobility flows, analyzing institutional affiliations and collaboration patterns. However, such methods have limitations for investigating the scientific diaspora, as they do not allow the identification of researchers’ nationality or birthplace. The aim of this article is to propose a multi-method approach to overcome these limitations, combining bibliometric techniques with supplemental sources, such as academic CV, institutional databases, and qualitative information. We applied this methodology to study scientific collaborations on COVID-19 involving the Brazilian scientific diaspora from 2020 to 2022, a period characterized by intense international cooperation. This analysis included variables such as gender, academic background, professional activity, and co-authorship patterns. Results show that the proposed approach enables more robust identification of diaspora researchers and their interactions with Brazil, which can provide relevant insights for science policies and engagement strategies of the diaspora. We conclude that the combination of bibliometric and qualitative data is essential for a better understanding of academic mobility and scientific diaspora dynamics, thereby contributing to the development of more effective policies for managing highly qualified human capital.

    Universities contribute to innovation systems through scientific production, intellectual property protection, technology transfer, and academic–corporate collaboration. Innovation-related outputs depend on combinations of organizational, institutional, and research-related conditions rather than isolated variables. This article examines innovation-related performance in Brazilian federal universities using data from 69 institutions collected by the Brazilian Office of the Comptroller General. The study analyzes intellectual property assets, technology transfer rate, and patent-cited scholarly output through descriptive statistics, correlation analyses, and fuzzy-set Qualitative Comparative Analysis (fsQCA). The findings show that academic–corporate collaboration is the most consistent condition associated with stronger innovation-related performance. Internal regulation enables intellectual property generation and technology transfer, while field-weighted citation impact is particularly relevant for patent-cited scholarly output. Institutional age is not a linear predictor of innovation-related performance, as younger universities appear prominently in normalized indicators. The article provides configurational evidence from a public higher education system in an emerging economy.

    Academic mobility is a central issue in the study of academic professions, shaping career trajectories, institutional dynamics, and the distribution of knowledge production. While international research has explored its determinants and implications, evidence from Global South contexts remains scarce. Brazil, with one of the largest higher education systems in the world, provides a valuable case to examine how institutional, sociodemographic, and policy factors shape academic mobility. This study investigates the employment trajectories of professors affiliated with Brazilian higher education institutions between 2003 and 2021, based on microdata from the Annual Social Information Report (RAIS). The analysis accounts for gender, age, degree, institutional type, distance, and remuneration. Nearly half of faculty (46.9%) experienced at least one mobility event, but mobility is highly segmented: it is concentrated in teaching-intensive private institutions, while research-intensive and graduate-oriented public universities exhibit markedly lower mobility and stronger retention. Most moves occur within the same institutional segment, suggesting barriers to entry and circular mobility within less prestigious tiers. Spatial mobility is likewise concentrated: 62.6% of moves occur within 0–50 km and 28.1% within 50–500 km, with evidence of greater geographic anchoring later in the career. Salary effects are asymmetric by direction: transitions from public to private institutions are associated with short-term wage losses, whereas moves from private to public institutions show sizable gains that materialize more gradually. The study contributes original evidence to the international literature on academic mobility, while also highlighting data limitations in Brazil. It calls for complementary qualitative research and deeper exploration of labor precarization in the private sector.

    BACKGROUND AND AIMS: Understanding how plant traits mediate adaptation and diversification across contrasting environments remains a major challenge in evolutionary ecology. This gap is especially evident in the Neotropics, where Savannas and Seasonally Dry Tropical Forests (SDTFs), represented here by the Cerrado and Caatinga phytogeographic domains, differ markedly in climate and ecological filters, yet remain underrepresented in trait-based evolutionary studies. Here, we investigated the evolutionary history of Discocactus (Cactaceae) to identify which morphological characters are associated with species occurrence across these contrasting biomes and to place these patterns within a phylogenetic and temporal framework. METHODS: We generated a time-calibrated phylogenomic hypothesis for Discocactus using the Cactaceae591 probe set and integrated predictive machine learning, ancestral state reconstruction, and phylogenetic comparative analyses to identify morphological characters associated with species occurrence in the Savanna and SDTF biomes. KEY RESULTS: We recovered the first dated phylogeny for Discocactus, providing evidence for the recognition of 16 distinct species, including the reinstatement of D. boomianus. Divergence-time analyses indicate that the genus originated in the Pliocene and diversified rapidly during the Plio-Pleistocene transition, particularly within a major Savanna-associated clade. Across analyses, flower length and stem diameter emerged as the main morphological characters associated with biome occupancy. Both characters also showed significant associations with climatic variation in phylogenetically informed regression analyses, with SDTF species tending to have shorter flowers and smaller stems than Savanna species. CONCLUSIONS: Our results provide a robust phylogenomic framework for interpreting diversification in Discocactus and show that morphological differentiation within the genus is associated with ecological contrasts between Neotropical SDTF and Savanna biomes. By integrating phylogenomics, predictive modeling, and phylogenetic comparative methods, this study highlights how genomic and trait-based approaches can help explain character evolution and diversification across contrasting environments.
