This study adopts the concept of ‘critical growth pathway’ to conduct a comparative analysis of academicians’ educational trajectories in China and Japan from the perspectives of educational continuity, educational institution diversity, and study abroad experience. Chinese academicians typically follow one of three education trajectories: (1) bachelor’s, (2) bachelor’s-master’s-doctorate, or (3) bachelor’s-work-master’s-work-doctorate, while Japanese academicians commonly follow: (1) bachelor’s-direct doctorate, (2) bachelor’s-master’s-doctorate, and (3) bachelor’s-work-doctorate. China tends to emphasise bachelor’s-master’s continuity and master’s-doctorate continuity, whereas Japan shows a stronger preference for direct doctoral continuity. Chinese academicians demonstrate greater diversity in their educational institutions compared to their Japanese counterparts. Most Chinese and Japanese academicians have no overseas study experience, although such experience is more common in Japan than China. Consistent and continuous scientific research training is a critical pathway for cultivating elite scientists, while maintaining coherence across educational stages supports their development. The role of overseas education in cultivating high-level domestic talent is important to reassess, attention should be placed on strengthening local talent development by enhancing mentorship, improving the effectiveness of domestic training systems, and addressing country-specific challenges, particularly as national research and education systems reach more advanced stages. The analytical model developed in this study provides valuable insights for institutional design in policy-driven latecomers and other developing countries.</div></div>","PeriodicalId":48662,"journal":{"name":"Journal of Informetrics","volume":"19 3","pages":"Article 101689"},"PeriodicalIF":3.4,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its importance, most studies have focused on delayed recognition at the paper level, leaving a gap in understanding how this phenomenon unfolds at the level of individual scientists. This paper presents a novel framework for quantifying delayed recognition in scientists by analyzing their career-level citation trajectories. The framework utilizes two key metrics—the author beauty coefficient (<span><math><mi>AB</mi></math></span>) and author career awakening time (<span><math><msub><mi>A</mi><mrow><mi>t</mi><mi>α</mi></mrow></msub></math></span>)—to capture the temporal dynamics of a scientist’s citation impact over the course of their career. Our analysis demonstrates that these metrics reveal patterns distinct from paper-level measures, with no significant correlation to averaged paper delayed recognition scores. Fixed-effect regression analyses indicate that female scientists and those pursuing novel or disruptive research experience greater delays in recognition. Additionally, through Coarsened Exact Matching (CEM) analysis, we find that scientists in smaller groups exhibit higher survival rates in academia but also face more significant delayed recognition. This paper delivers a fresh methodological approach and critical insights into the demographic and research factors driving delayed recognition, enhancing our understanding of scientific impact at the individual level.</div></div>","PeriodicalId":48662,"journal":{"name":"Journal of Informetrics","volume":"19 3","pages":"Article 101688"},"PeriodicalIF":3.4,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144255149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focusing on Nobel laureates in the natural sciences from 1901 to 2023 and their Nobel Prize-winning research (NPw), we construct negative binomial regression models to analyze these variables. Our findings reveal that interdisciplinarity has no significant effect on HSt, but it significantly and positively affects SNt and HNt. This suggests that while interdisciplinary approaches do not delay the initial discovery process, they substantially extend the time required for scientific recognition and award.

No significant gender differences were found in retractions attributed to mistakes. Furthermore, male first authors experience significantly higher retraction rates in biomedical and health sciences, as well as in life and earth sciences, whereas female first authors have higher retraction rates in mathematics and computer science.

The empirical examination is conducted using two datasets related to CRISPR and fullerene, derived from the Web of Science. Our findings highlight a markedly higher level of involvement within universities compared to industries and governments, attributed to the dominant proportion of universities.

We further contrast <em>IV</em> and <em>IA</em> with the triple helix and transmission efficiency metrics, observing distinct differences among them. Consequently, we suggest that through the synthesis of the triple helix and diversity, <em>IV</em> and <em>IA</em> provide a more thorough understanding of involvement and interaction within U-I-G relations, and can inform strategies for their enhancement.
