    Beyond counting tweets: An exploration of scholarly conversations on Twitter(opens in a new tab)

    Shen, Yan; Dudek, Jonathan; Costas, Rodrigo

    Funded by China Scholarship Council

    Academic discussions on Twitter have increased over the past decade. This study analyzes ca. 1.3 million scholarly conversations on Twitter, examining their temporal evolution, topical distribution, and associated publications. The results show a steady growth in the number of scholarly conversations, accompanied by rising proportions of longer and multi‐topic conversations. The visibility of different disciplines and topics varies significantly, with popular themes often closely related to societal events. By comparing topic co‐occurrence networks in Twitter conversations with co‐citation networks in scholarly literature, the study reveals both commonalities and differences in topic structures across academic and non‐academic communication contexts. Moreover, publications that appear in multiple conversations are associated with higher citation counts, suggesting a potential link between conversational engagement and scholarly impact. These findings highlight that the feature of conversations on social media has value not only for refining indicators of scholarly attention and influence beyond simple mention counts, but also to capture more broadly how research is disseminated online.

    This study investigates the perceptions of Brazilian researchers in agronomy regarding the order of authorship and the role of the corresponding author in scientific publications utilizing a survey of 380 responses. Key findings reveal that most researchers see the first author as the primary executor of the research, and the last author as the leader. The study also highlights a significant association between authorship order, research credibility, and citation impact, with differing views based on the type of institutional affiliation. In addition, the survey shows a preference for the corresponding author to be either the first or the last author, emphasizing their role in communication with journals. The results suggest that while the authorship order is crucial for recognizing contributions, the corresponding author’s role is primarily seen as a formality. The study calls for more precise guidelines on authorship practices and further research into authorship dynamics in different scientific fields.

    Operationalising journals' communication functions through citation patterns and local dimensions(opens in a new tab)

    Di Césare, Victoria; Robinson-García, Nicolás; Costas, Rodrigo

    This preliminary study operationalises the knowledge bridging and gap-filling communication functions of scientific journals, originally proposed by Chavarro et al. (2017). Considering their theoretical definitions, we link these functions to our local research framework (Di Césare & Robinson-Garcia, 2026) through the producers and recipients dimensions, and measure them using local or global references and citations drawn from OpenAlex articles. We aim to empirically identify knowledge bridging and gap-filling journals, both within and outside the mainstream. The results suggest that the vast majority of these journals are non-mainstream. The thematic profiles of their references and citations validate our geographical operationalisations. Gap-filling journals belong predominantly to the non-mainstream local Social Sciences, whereas in the non-mainstream knowledge bridging journals, the Health Sciences emerge. These domain-level findings support the journals' theoretical functions of serving, respectively, as venues for the publication of knowledge overlooked by the mainstream, and as bridges between mainstream knowledge and local communities.

    Exclusive Bibliographic Coupling: identifying the influence of co-authorship on the identification of scientific domains(opens in a new tab)

    Moutinho, Sônia Oliveira Matos; Grácio, Maria Cláudia Cabrini; Perianes-Rodriguez, Antonio

    This study proposes Exclusive Bibliographic Coupling (EBC) as a methodological alternative to mitigate the influence of co-authorship in bibliographic coupling networks. The method excludes co-author relationships while preserving organic links between non-collaborators. The comparison between the traditional model and EBC includes analyses of author networks to demonstrate that the exclusive method reduces the appearance of links resulting from collaboration, preserving connections based on the theoretical convergence of authors' citation identities. It has been determined that EBC increases the accuracy of identifying cognitive structures and scientific domains, contributing to more consistent and reliable bibliometric analyses.

    La dinámica local-global de la circulación del conocimiento en una facultad de ciencias bioquímicas de una universidad pública argentina: aportes para repensar los sistemas de evaluación científica en América Latina(opens in a new tab)

    Cybulski, Larisa E.; Isuani, Gabriela; Sciara, Andrés A.; Pacífico, Fernando Díaz; Pallitto, Nahuel; Beigel, Fernanda

    Since the establishment of the Science Citation Index in the 1960s, scientific evaluation systems have favored metrics like the impact factor (IF), creating a hierarchy that privileges “mainstream” journals while marginalizing local publications. This model has driven Latin American researchers to publish in international journals, often in English and with high article processing charges (APCs), to gain academic recognition and funding. However, this dynamic has undervalued regional journals, despite initiatives like SciELO, RedALyC, and Latindex demonstrating high standards of quality, open access, and increasing internationalization. In response, an interdisciplinary team proposed the creation of a local scientific journal at the Faculty of Biochemical and Pharmaceutical Sciences of the National University of Rosario (FBIOyF, by its Spanish acronym), aiming to engage globally without neglecting local values and criteria. To assess this initiative, we conducted a survey among faculty researchers. The results reveal significant interest in a publication that promotes the dissemination of locally generated knowledge, facilitates access for non-English-speaking communities, and fosters interdisciplinary collaborations, making science more equitable and more sensitive to social context.

    Different operationalizations of local research and their associated citation patterns: A study of African publications(opens in a new tab)

    Alonso-Álvarez, Patricia; Boshoff, Nelius

    Local research has gained increasing attention in recent years, with a growing body of literature emphasizing its significance—especially for peripheral communities underrepresented in mainstream scientific discourse. However, despite this growing interest, there remains no clear consensus on how to define local research. Conceptual clarity is essential for conducting consistent and replicable analyses that capture the specific characteristics, contexts, and societal relevance of local research. This need is particularly acute in the Global South, where structural inequalities in visibility and recognition often marginalize regionally focused scholarship. In Africa, for instance, a substantial share of research is published in local or regional journals that are poorly represented in global indexing databases. As bibliometric analyses typically rely on these databases, this exclusion diminishes their perceived relevance. To address this gap, the present study incorporates data from regional and open-access sources to examine citation patterns associated with African local research. It uses multiple conceptualizations of local research to classify publications as either local or non-local depending on the definition used. These classifications are correlated with three citation-based indicators: average citations per publication, time to first citation, and the proportion of uncited publications. Additionally, the study explores the characteristics of citing publications, distinguishing between local and non-local sources as well as domestic and international citations. The findings reveal that citation patterns differ significantly across locality definitions, underscoring the importance of adopting nuanced, context-sensitive approaches to assess and support local research.

    A global map of science according to a topic model of EU grants(opens in a new tab)

    Vidal, Adrià Plazas; Bovenzi, Nicandro; Durán-Silva, Nicolau; Martí, Enric Fuster; Ràfols, Ismael

    Since their appearance in the 1980s, global maps of science have proved useful to locate the relative position of topics and organisations in large scientific landscapes, providing strategic information for portfolio analyses in science policy. At this global level (global meaning here ‘all disciplines’), these maps have been based on publications and have mostly used citations to build the relationship between scientific fields. Here, we present a comprehensive scientific map based on grant data that uses semantic analyses (BERT-based topic modelling) to provide the overall landscape of science based on grant data from the European Union since 2003 (since the 6th framework programme). We find a disciplinary structure which is consistent with the circular shape of publication and citation based global science maps. However, this grant map shows a much larger presence of applied science and mission-oriented research, such as engineering and sustainability sciences. We provide examples of how this landscape can be used as a baseline to explore the specialisation of territories (regions), organisations (universities) and funding programmes.

    Funding, authorship patterns, and citation impact of articles funded by Ukrainian agencies before and during Russia’s full-scale war (2020–2023)(opens in a new tab)

    Hladchenko, Myroslava; Costas, Rodrigo

    Funded by European Commission

    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.

    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.
