EXECUTIVE SUMMARY AND STRATEGIC VISION

Ecole Centrale de Nantes demonstrates a robust scientific integrity profile, with an overall score of -0.205 indicating performance that is generally well-aligned with global standards of good practice. The institution's primary strengths lie in its exceptional governance of collaborative affiliations, selection of publication venues, and management of institutional journals, where risks are virtually non-existent. However, this strong foundation is contrasted by two areas of medium risk that require strategic attention: the Rate of Retracted Output and the Rate of Redundant Output. These vulnerabilities in publication quality control could, if unaddressed, detract from the institution's otherwise excellent research standing. According to SCImago Institutions Rankings data, the institution holds a strong national position in key thematic areas, particularly in Social Sciences, Physics and Astronomy, and Earth and Planetary Sciences. While the institution's specific mission statement was not available for this analysis, any mission centered on academic excellence and social responsibility is inherently challenged by integrity risks. Ensuring the rigor and originality of every publication is crucial to upholding these values. Overall, Ecole Centrale de Nantes has a solid integrity framework; a targeted review of pre-publication support and authorship guidelines will help mitigate the identified risks and fully align its operational practices with its evident research strengths.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -1.002, in stark contrast to the national average of 0.648. This result signals a clear case of preventive isolation, where the institution successfully avoids risk dynamics that are more common at the national level. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, disproportionately high rates can signal strategic attempts to inflate institutional credit. The institution's very low score indicates that its collaborative practices are transparent and well-governed, avoiding any suggestion of “affiliation shopping” and reinforcing a culture of clear, accountable research partnerships.

Rate of Retracted Output

The institution's Z-score for retracted output is 0.230, showing a moderate deviation from the national average of -0.189. This suggests a greater sensitivity to risk factors than its national peers. Retractions are complex events: some result from the honest correction of unintentional errors, signifying responsible supervision. However, a rate significantly higher than the global average alerts to a vulnerability in the institution's integrity culture. This score suggests that quality control mechanisms prior to publication may be failing systemically, indicating possible recurring malpractice or a lack of methodological rigor requiring immediate qualitative verification by management.

Rate of Institutional Self-Citation

With a Z-score of -0.108, the institution's rate of self-citation is slightly higher than the national average of -0.200, pointing to an incipient vulnerability. A certain level of self-citation is natural and reflects the continuity of established research lines. Nonetheless, a value that begins to separate from the national baseline can signal the early stages of concerning scientific isolation or 'echo chambers' where the institution validates its own work without sufficient external scrutiny. This signal warrants review to prevent the potential for endogamous impact inflation, ensuring the institution's academic influence is driven by global community recognition rather than internal dynamics.

Rate of Output in Discontinued Journals

The institution shows a Z-score of -0.410, which is in almost perfect alignment with the national average of -0.450. This demonstrates integrity synchrony, reflecting a shared environment of maximum scientific security in the selection of publication venues. A high proportion of output in discontinued journals would constitute a critical alert regarding due diligence. The institution's very low score confirms that its researchers are effectively avoiding channels that do not meet international ethical or quality standards, thereby protecting the institution from reputational risks associated with 'predatory' or low-quality practices.

Rate of Hyper-Authored Output

The institution's Z-score of -0.891 is significantly lower than the national average of 0.859, a medium-risk value. This gap highlights the institution's resilience, as its internal control mechanisms appear to successfully mitigate systemic risks present in the country. While extensive author lists are legitimate in 'Big Science' contexts, a high Z-score outside these fields can indicate author list inflation, diluting individual accountability. The institution's low score suggests its authorship practices are well-regulated, effectively distinguishing between necessary massive collaboration and potentially problematic 'honorary' or political authorship.

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

The institution has a Z-score of -0.477, which is substantially better than the national average of 0.512. This demonstrates strong institutional resilience, suggesting that its control mechanisms are effectively mitigating a risk that is more prevalent at the national level. A wide positive gap signals a sustainability risk where prestige is dependent on external partners rather than internal capacity. The institution's low score indicates that its scientific prestige is structural and endogenous, reflecting a healthy balance where its excellence metrics result from real internal capacity and intellectual leadership in its collaborations.

Rate of Hyperprolific Authors

With a Z-score of -0.851, the institution displays a more prudent profile compared to the national average of -0.654. This indicates that its processes are managed with more rigor than the national standard. While high productivity can evidence leadership, extreme individual publication volumes often challenge the limits of meaningful intellectual contribution. The institution's lower-than-average score suggests it effectively fosters a research environment that avoids potential imbalances between quantity and quality, mitigating risks such as coercive authorship or the assignment of authorship without real participation.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is slightly below the national average of -0.246, indicating total operational silence in this area. This performance, even better than the already low national benchmark, confirms an absence of risk signals. In-house journals can raise conflicts of interest if used excessively, creating a risk of academic endogamy where production bypasses independent peer review. The institution's negligible rate of publication in its own journals demonstrates a firm commitment to external, competitive validation, ensuring its research achieves global visibility and credibility.

Rate of Redundant Output

The institution's Z-score of 1.884 reveals high exposure to this risk, as it is significantly more pronounced than the national average of 0.387. This suggests the center is more prone to showing alert signals in this area than its environment. Citing previous work is necessary for cumulative knowledge, but massive and recurring bibliographic overlap between simultaneous publications usually indicates data fragmentation or 'salami slicing.' This high value alerts to the practice of dividing a coherent study into minimal publishable units to artificially inflate productivity, a behavior that distorts available scientific evidence and prioritizes volume over significant new knowledge.
