Aristotle University of Thessaloniki

EXECUTIVE SUMMARY AND STRATEGIC VISION

Aristotle University of Thessaloniki presents a balanced integrity profile, with an overall risk score of -0.034 that indicates a general alignment with expected international standards. The institution demonstrates significant strengths in foundational research practices, showing very low risk in publishing within its own journals and low risk concerning retracted output, multiple affiliations, and publication in discontinued journals. However, a cluster of medium-risk indicators emerges around authorship, citation, and impact patterns, including institutional self-citation, hyperprolific authors, a notable gap in impact leadership, and redundant publications. These areas warrant strategic attention. According to SCImago Institutions Rankings data, this operational profile underpins a position of national leadership in research, with the university ranking first in Greece in diverse and critical fields such as Computer Science, Environmental Science, Social Sciences, and Veterinary. This thematic excellence is a core asset, but the identified risks could challenge the institution's mission to enhance "excellence in research" and its "international presence." Practices that may lead to endogamous impact or prioritize publication volume over substance could be perceived as misaligned with a commitment to genuine excellence and global recognition. By proactively addressing these moderate vulnerabilities, the university can ensure its operational integrity fully supports its academic prestige, solidifying its role as a benchmark for quality and social responsibility.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution exhibits a Z-score of -0.531, which is notably lower than the national average of -0.253. This indicates a prudent and rigorous approach to managing author affiliations, surpassing the standard practice within the country. While multiple affiliations can be a legitimate outcome of collaboration, the university's controlled rate suggests its researchers are not engaging in strategic "affiliation shopping" to inflate institutional credit. This disciplined profile reinforces transparency and clear attribution of research output, reflecting sound governance that is more stringent than the national norm.

Rate of Retracted Output

With a Z-score of -0.277, the institution demonstrates a very low rate of retractions, contrasting sharply with the medium-risk national average of 0.054. This divergence highlights a notable institutional resilience, suggesting that the university's quality control and supervision mechanisms are effectively mitigating a systemic risk present elsewhere in the country. A low retraction rate is a sign of a healthy integrity culture, where pre-publication methodological rigor and ethical oversight successfully prevent the kind of recurring errors or malpractice that might be affecting peer institutions at a national level.

Rate of Institutional Self-Citation

The institution's Z-score for self-citation is 0.288, placing it in the medium-risk category and notably above the national average of 0.155. This reveals a higher exposure to this particular risk compared to its national peers. While a degree of self-citation reflects focused research lines, this elevated rate could signal the formation of scientific "echo chambers." It warns of a potential for endogamous impact inflation, where the institution's academic influence might be disproportionately validated by internal dynamics rather than by broader recognition from the global scientific community, a trend that requires closer examination.

Rate of Output in Discontinued Journals

The university's Z-score of -0.200 is statistically normal and almost identical to the national average of -0.195. This alignment indicates that the institution's risk level for publishing in journals that fail to meet international standards is as expected for its context. The data suggests that the university's researchers exercise a standard level of due diligence in selecting publication venues, effectively avoiding the reputational damage and wasted resources associated with predatory or low-quality publishing practices at a rate consistent with their national counterparts.

Rate of Hyper-Authored Output

With a Z-score of 0.576, the institution's rate of hyper-authored publications is in the medium-risk range, closely mirroring the national average of 0.622. This similarity suggests that the university's authorship patterns are not an institutional anomaly but rather reflect a systemic practice shared at the national level. This indicator serves as a signal to distinguish between necessary massive collaboration, common in "Big Science," and potential author list inflation. The alignment with the national trend points towards shared disciplinary norms or academic incentives in the country rather than a specific institutional vulnerability.

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

The institution shows a Z-score of 0.586 in this indicator, a medium-risk value that is significantly higher than the national average of 0.371. This high exposure indicates a greater-than-average gap between the impact of its overall output and the impact of research where it holds a leadership role. This wide positive gap signals a potential sustainability risk, suggesting that the university's scientific prestige may be heavily dependent on external partners rather than being structurally generated from within. It invites strategic reflection on whether its high-impact metrics stem from genuine internal capacity or from positioning in collaborations where it does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The university's Z-score of 0.661 is in the medium-risk category and is considerably higher than the national average of 0.402. This indicates that the institution has a greater concentration of authors with extreme publication volumes than its national peers. Such a high rate alerts to potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of credit without meaningful intellectual contribution. This pattern warrants a review to ensure that institutional incentives are not inadvertently prioritizing raw metrics over the integrity of the scientific record.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution demonstrates a very low risk in this area, showing perfect synchrony with the national average of -0.260. This total alignment with a secure environment indicates that the university is not dependent on its in-house journals for publication. This practice reinforces its commitment to external validation and global visibility, effectively avoiding potential conflicts of interest or academic endogamy where production might bypass independent peer review. The institution's behavior is a model of integrity in this regard, fully consistent with the best practices observed nationally.

Rate of Redundant Output (Salami Slicing)

The institution's Z-score of 0.610 places it in the medium-risk category, showing a higher exposure to this practice than the national average of 0.506. This elevated rate of massive bibliographic overlap between publications is an alert for "salami slicing," where a single body of research may be fragmented into multiple minimal units to artificially inflate productivity metrics. This practice not only overburdens the peer-review system but also distorts the scientific record by prioritizing publication volume over the communication of significant, coherent new knowledge. The university's higher propensity for this behavior compared to its peers suggests a need to reinforce policies that encourage comprehensive research reporting.
