Politecnico di Milano

EXECUTIVE SUMMARY AND STRATEGIC VISION

Politecnico di Milano demonstrates a robust and commendable scientific integrity profile, reflected in an overall risk score of -0.074. The institution's primary strengths lie in its capacity for generating high-impact research with strong internal leadership, its exemplary selection of publication venues, and its effective resistance to national trends of authorship inflation. These positive indicators are further validated by its outstanding international leadership, holding the #1 national rank in the SCImago Institutions Rankings in critical areas such as Business, Management and Accounting; Computer Science; Energy; Engineering; Mathematics; and Physics and Astronomy. However, areas of moderate risk have been identified, particularly a high exposure to institutional self-citation and redundant publications, which are more pronounced than the national average. These vulnerabilities, if unaddressed, could subtly undermine the institution's mission to foster "social, economic and cultural development," as this objective relies on research that is not only excellent but also transparent, credible, and globally validated. To fully align its operational practices with its strategic vision, it is recommended that the institution leverage its significant strengths to address these specific integrity challenges, thereby solidifying its position as a beacon of both scientific excellence and responsible research conduct.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score for this indicator is -0.284, slightly higher than the national average of -0.497. This suggests an incipient vulnerability, as the center shows low-level signals of this activity that are somewhat more frequent than the national standard. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, this slight elevation warrants a review to ensure that all affiliations are substantive and not strategic attempts to inflate institutional credit through practices like “affiliation shopping.”

Rate of Retracted Output

With a Z-score of -0.024, the institution's rate of retractions is marginally higher than the country's baseline of -0.244. Although the overall risk remains low, this subtle difference points to an incipient vulnerability. Retractions can signify responsible supervision when correcting honest errors. However, a rate that edges above the national norm, even slightly, suggests that quality control mechanisms prior to publication could be reinforced to prevent potential systemic failures and protect the institution's integrity culture from recurring malpractice or a lack of methodological rigor.

Rate of Institutional Self-Citation

The institution presents a Z-score of 1.239 in this area, which is notably higher than the national average of 0.340. This indicates a high exposure to this particular risk factor, suggesting the institution is more prone to these dynamics than its national peers. A certain level of self-citation is natural, reflecting the continuity of established research lines. However, this disproportionately high rate signals a potential concern regarding scientific isolation or 'echo chambers' where the institution validates its own work without sufficient external scrutiny. This value warns of the risk of endogamous impact inflation, suggesting that the institution's academic influence may be oversized by internal dynamics rather than global community recognition.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.373 is well below the national average of -0.290, demonstrating low-profile consistency in a very low-risk area. This excellent result indicates that the institution's researchers exercise strong due diligence in selecting dissemination channels, effectively avoiding a risk that, while low, is more present at the national level. This performance highlights a robust information literacy culture that protects the institution from the reputational and resource risks associated with 'predatory' or low-quality publishing practices.

Rate of Hyper-Authored Output

With a Z-score of -0.219, the institution operates at a low-risk level, in stark contrast to the significant risk level seen in the national average of 1.457. This demonstrates that the institution acts as an effective filter, successfully functioning as a firewall against national risk practices related to author list inflation. This strong governance suggests a clear understanding of when extensive author lists are legitimate, as in 'Big Science,' versus when they might indicate 'honorary' authorship, thereby preserving individual accountability and transparency.

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

The institution shows an exceptionally strong Z-score of -1.187, indicating a very low-risk profile, while the country as a whole operates at a medium-risk level (0.283). This signifies a state of preventive isolation, where the center does not replicate the risk dynamics observed in its environment. The result suggests that the institution's scientific prestige is structural and sustainable, built upon real internal capacity and intellectual leadership, rather than being dependent on the impact generated by external collaborators. This is a hallmark of a mature and self-sufficient research ecosystem.

Rate of Hyperprolific Authors

The institution's Z-score of 0.224 places it at a medium-risk level, yet it is significantly lower than the national average of 0.625. This reflects a differentiated management approach, where the center successfully moderates a risk that appears more common across the country. While the presence of hyperprolific authors warrants attention due to potential imbalances between quantity and quality, the institution shows more control over this dynamic than its peers. This suggests a healthier balance and a lower risk of practices like coercive authorship or assigning credit without real participation.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution's activity in this area is even lower than the country's already minimal score of -0.177. This signals a state of total operational silence, with an absence of risk signals that is exemplary even when compared to a low-risk national environment. This performance underscores a strong commitment to independent, external peer review and global visibility, effectively mitigating any risks of academic endogamy or conflicts of interest that can arise from excessive dependence on in-house publication channels.

Rate of Redundant Output

The institution's Z-score of 0.975 is considerably higher than the national average of 0.224, indicating high exposure to this risk. This suggests the institution is more prone than its environment to practices where a coherent study is fragmented into minimal publishable units to artificially inflate productivity. This high value serves as an alert for 'salami slicing,' a practice that can distort the available scientific evidence and overburden the review system by prioritizing volume over the generation of significant new knowledge. This area requires careful review to ensure research outputs are substantive.
