Maastricht University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Maastricht University presents a robust scientific integrity profile, characterized by an overall low-risk score of -0.059. The institution demonstrates exceptional strengths in maintaining very low rates of redundant output, publication in discontinued journals, and use of institutional journals, indicating a strong culture of quality and ethical dissemination. This solid foundation is complemented by a prudent approach to institutional self-citation, which is managed with greater rigor than the national average. However, areas requiring strategic attention emerge in indicators related to authorship and collaboration, such as the Rate of Multiple Affiliations, which shows a moderate deviation from the national standard. These observations are contextualized by the university's outstanding performance in the SCImago Institutions Rankings, where it holds top-tier national positions in key fields like Medicine (7th in the Netherlands), Economics, Econometrics and Finance (7th), and Psychology (8th). While the identified vulnerabilities do not currently represent a critical threat, they warrant proactive management to ensure they do not undermine the core institutional mission. A commitment to social responsibility and sustainability requires unimpeachable transparency in authorship and affiliation practices; addressing these moderate risks will reinforce the university's reputation as an innovator in education and research, ensuring its excellence is built upon a foundation of unquestionable integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 1.351 contrasts with the national average of -0.033. This moderate deviation suggests that the university exhibits a greater sensitivity to risk factors associated with affiliation practices than its national peers. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, this elevated rate warrants a review of internal patterns. The discrepancy with the low-risk national context could signal strategic attempts to inflate institutional credit or instances of “affiliation shopping” that, if unmonitored, could compromise the transparency of institutional contributions.

Rate of Retracted Output

With a Z-score of -0.324, which is slightly higher than the national average of -0.277, the institution shows an incipient vulnerability in this area. Although the overall risk remains low, this subtle increase compared to the national baseline suggests that pre-publication quality control mechanisms may warrant a preventative review. Retractions are complex events, and a rate significantly higher than the average can alert to a systemic vulnerability in the institution's integrity culture. Monitoring this indicator is crucial to ensure that potential issues related to recurring malpractice or a lack of methodological rigor are addressed before they escalate.

Rate of Institutional Self-Citation

The institution demonstrates a prudent profile with a Z-score of -0.584, which is notably lower than the national average of -0.383. This indicates that the university manages its citation practices with more rigor than the national standard, effectively mitigating the risks of scientific isolation. A certain level of self-citation is natural, reflecting the continuity of research lines. However, the university's lower rate confirms that its academic influence is validated by the global community rather than being oversized by internal dynamics, successfully avoiding the 'echo chambers' that can lead to endogamous impact inflation.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.470 is almost identical to the national average of -0.494, placing both in a very low-risk category. However, the university's score is marginally higher, representing a form of residual noise in an otherwise inert environment. While the risk is minimal, this faint signal serves as a reminder of the importance of due diligence in selecting dissemination channels. Even a sporadic presence in discontinued journals can expose the institution to reputational risks, highlighting the ongoing need for information literacy to avoid channeling resources toward low-quality or predatory media.

Rate of Hyper-Authored Output

With a Z-score of 0.752, the institution shows a more controlled approach to a risk that is common nationally, where the average is 0.843. This reflects a differentiated management strategy that moderates the trend toward hyper-authorship. Outside of 'Big Science' contexts, extensive author lists can indicate inflation, diluting individual accountability. The university's ability to maintain a lower rate than its peers suggests that its governance mechanisms are more effective at distinguishing between necessary massive collaboration and potentially problematic 'honorary' authorship practices.

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

The institution's Z-score of 0.289 indicates a higher exposure to this risk compared to the national average of 0.085. This suggests that the university is more prone to showing a dependency on external partners for its citation impact. A wide positive gap, where global impact is high but the impact of institution-led research is lower, signals a potential sustainability risk. This disparity invites reflection on whether the university's excellence metrics result from its own structural capacity or from strategic positioning in collaborations where it does not exercise primary intellectual leadership, making its scientific prestige potentially dependent and exogenous.

Rate of Hyperprolific Authors

The institution demonstrates effective management in this area, with a Z-score of 0.262 that is significantly lower than the national average of 0.444. This indicates that the university successfully moderates a risk that appears more common across the country. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution and may point to risks such as coercive authorship or 'salami slicing'. By maintaining a lower rate, the institution signals a healthier balance between quantity and quality, prioritizing the integrity of the scientific record over the simple inflation of metrics.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is slightly higher than the national average of -0.245, though both are in the very low-risk category. This minimal signal can be interpreted as residual noise in a secure environment. While the current level is not alarming, it serves as a reminder of the potential conflicts of interest that arise when an institution acts as both judge and party in the publication process. Maintaining this low rate is crucial to avoid any perception of academic endogamy or the use of internal channels as 'fast tracks' that bypass independent external peer review.

Rate of Redundant Output

The institution exhibits low-profile consistency and exemplary practice with a Z-score of -0.498, placing it in the very low-risk category and well below the national low-risk average of -0.302. This absence of risk signals aligns with and improves upon the national standard. A high rate of bibliographic overlap often indicates data fragmentation or 'salami slicing' to artificially inflate productivity. The university's excellent performance in this indicator demonstrates a strong commitment to publishing significant new knowledge over volume, thereby protecting the integrity of the scientific evidence base.
