Institut National des Sciences Appliquees de Rennes

EXECUTIVE SUMMARY AND STRATEGIC VISION

Institut National des Sciences Appliquees de Rennes demonstrates a robust scientific integrity profile, reflected in an overall score of -0.345, which indicates performance superior to the global baseline. The institution exhibits remarkable strengths in maintaining very low-risk levels for multiple affiliations, retracted output, and redundant publications, effectively insulating itself from less favorable national trends. This solid foundation is complemented by strong performance in the SCImago Institutions Rankings, particularly in key thematic areas such as Environmental Science (ranked 14th in France), Biochemistry, Genetics and Molecular Biology (16th), and Energy (17th). However, the analysis also highlights three areas requiring strategic attention: a moderate rate of institutional self-citation, a notable gap between overall impact and the impact of institution-led research, and a tendency towards hyperprolific authorship. While the institution's specific mission was not available for this analysis, these risk signals could challenge universal academic values of excellence and social responsibility. An over-reliance on self-citation or external leadership for impact may undermine claims of genuine, internally-driven excellence. A proactive approach to addressing these vulnerabilities will be crucial to ensure that quantitative achievements are fully aligned with a culture of transparent and unimpeachable scientific practice, thereby reinforcing its position as a leading research institution.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -0.923, in stark contrast to the national average of 0.648. This demonstrates a clear operational divergence from the country's general trend, where multiple affiliations are more common. The institution's very low rate suggests it has successfully established a governance framework that prevents the replication of risk dynamics observed in its environment. While multiple affiliations can be a legitimate outcome of collaboration, disproportionately high rates can signal strategic attempts to inflate institutional credit. The institution’s position indicates a preventive isolation from such practices, reinforcing a culture of clear and unambiguous attribution of academic credit.

Rate of Retracted Output

With a Z-score of -0.503, the institution shows an extremely low incidence of retracted publications, a figure that is even more favorable than the country's already low-risk average of -0.189. This low-profile consistency suggests that the institution's quality control mechanisms are not only effective but exemplary within the national context. Retractions can sometimes result from the honest correction of errors, but a near-absence of such events, as seen here, points to a robust system of pre-publication review and a strong integrity culture that minimizes the risk of methodological failure or malpractice, ensuring the reliability of its scientific output.

Rate of Institutional Self-Citation

The institution's Z-score for this indicator is 0.157, a medium-risk value that deviates moderately from the national average of -0.200, which falls within the low-risk category. This suggests the institution is more sensitive to this risk factor than its national peers. A certain level of self-citation is natural, reflecting the continuity of research lines. However, this elevated rate could signal the formation of 'echo chambers' where the institution validates its own work without sufficient external scrutiny. This pattern warns of a potential for endogamous impact inflation and suggests that the institution's academic influence may be disproportionately shaped by internal dynamics rather than broader recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.410 is almost identical to the national average of -0.450, placing both in the very low-risk tier. This demonstrates a perfect integrity synchrony between the institution and its national environment. This shared commitment to avoiding problematic publication venues signifies a high level of due diligence in selecting dissemination channels. A low score here is critical, as it confirms that scientific production is not being channeled through media that fail to meet international ethical or quality standards, thereby protecting the institution from severe reputational risks associated with 'predatory' practices.

Rate of Hyper-Authored Output

With a Z-score of -0.395, the institution maintains a low-risk profile for hyper-authored publications, showing significant resilience against the national trend, where the average Z-score is 0.859 (medium risk). This suggests that the institution's internal control mechanisms are effectively mitigating a systemic risk prevalent in the country. While extensive author lists are legitimate in 'Big Science,' a controlled rate outside these contexts is a positive sign. It indicates that the institution successfully distinguishes between necessary massive collaboration and practices like 'honorary' authorship, thereby preserving individual accountability and transparency in its research contributions.

Gap between Impact of total output and the impact of output with leadership

The institution exhibits a Z-score of 1.037, a medium-risk value that indicates a significant gap. While this reflects a systemic pattern also observed nationally (country Z-score of 0.512), the institution's score is notably higher, suggesting it has a high exposure to this particular vulnerability. A wide positive gap, where overall impact is high but the impact of institution-led research is comparatively low, signals a sustainability risk. This result suggests that a significant portion of the institution's scientific prestige may be dependent and exogenous, stemming from collaborations where it does not exercise primary intellectual leadership rather than from its own structural capacity for high-impact research.

Rate of Hyperprolific Authors

The institution's Z-score of 0.072 places it in the medium-risk category, a moderate deviation from the national standard, which sits at a low-risk -0.654. This indicates a greater sensitivity within the institution to factors driving extreme publication volumes compared to its peers. While high productivity can be a sign of leadership, extreme volumes challenge the limits of meaningful intellectual contribution. This indicator serves as an alert for potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of credit without real participation—dynamics that prioritize metric inflation over the integrity of the scientific record.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution's publication rate in its own journals is very low and closely aligned with the national average of -0.246. This integrity synchrony reflects a shared national preference for external validation. By minimizing reliance on in-house journals, the institution effectively avoids potential conflicts of interest where it would act as both judge and party. This practice prevents academic endogamy, ensures its scientific production undergoes independent external peer review, and maximizes its global visibility by competing in standard, non-internal channels.

Rate of Redundant Output

The institution records a Z-score of -0.811, indicating a very low rate of redundant output. This performance represents a preventive isolation from the national trend, where the average Z-score of 0.387 falls into the medium-risk category. This discrepancy highlights the institution's success in avoiding the practice of 'salami slicing,' where a single study is fragmented into minimal units to artificially inflate productivity. By maintaining such a low rate, the institution demonstrates a commitment to publishing significant, coherent bodies of work, thereby protecting the integrity of scientific evidence and prioritizing new knowledge over volume.
