Hellenic Open University

EXECUTIVE SUMMARY AND STRATEGIC VISION

The Hellenic Open University presents a complex integrity profile, marked by a commendable overall score of 0.647 that reflects both significant strengths and critical areas for strategic intervention. The institution demonstrates robust internal governance in key areas, showing exceptional control over retracted output, redundant publications, and the use of institutional journals, positioning it as a resilient entity within the national context. However, this is contrasted by significant-risk alerts in the rates of multiple affiliations and hyper-authored output, which are severe discrepancies from the national standard and require immediate attention. According to SCImago Institutions Rankings data, the university's strongest thematic areas nationally include Arts and Humanities, Physics and Astronomy, Psychology, and Earth and Planetary Sciences. To fully align with its mission of providing "high-quality university education" and promoting "scientific research," it is imperative to address the identified vulnerabilities. Practices that suggest a focus on metric inflation over genuine contribution could undermine the very quality the institution pledges to uphold, creating a tension between its stated objectives and its operational outputs. A proactive review of authorship and affiliation policies will be crucial to safeguard its academic reputation and ensure its research excellence is both authentic and sustainable.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution exhibits a Z-score of 4.067, a figure that represents a severe discrepancy when compared to the country's low-risk Z-score of -0.253. This atypical level of risk activity, in a national context where it is not prevalent, demands a deep integrity assessment. While multiple affiliations can be legitimate, such a disproportionately high rate signals a potential systemic issue. It suggests that the institution may be vulnerable to strategic attempts to inflate institutional credit or "affiliation shopping," where researchers leverage multiple affiliations to maximize visibility and metrics. This practice can obscure the true origin of research contributions and requires a thorough review of institutional policies to ensure transparency and ethical conduct.

Rate of Retracted Output

With a Z-score of -0.334, the institution maintains a low-risk profile, demonstrating notable resilience against the medium-risk trend observed at the national level (Z-score of 0.054). This suggests that the university's internal control mechanisms are effectively mitigating systemic risks present in its environment. A low rate of retractions is a positive indicator, suggesting that quality control mechanisms prior to publication are functioning effectively. This performance points to a culture of responsible supervision and methodological rigor that prevents the kind of recurring errors or malpractice that might be affecting other institutions in the country.

Rate of Institutional Self-Citation

The institution's Z-score of 1.045 places it in the medium-risk category, similar to the national average of 0.155. However, the university's score is markedly higher, indicating a greater exposure to this risk factor compared to its national peers. A certain level of self-citation is natural, but this elevated rate could signal the formation of 'echo chambers' where work is validated internally without sufficient external scrutiny. This dynamic warns of a potential for endogamous impact inflation, suggesting that the institution's academic influence may be disproportionately shaped by internal citation practices rather than broader recognition from the global scientific community.

Rate of Output in Discontinued Journals

The university shows a moderate deviation from the national standard, with a medium-risk Z-score of 0.375, while the country maintains a low-risk profile (Z-score of -0.195). This indicates a greater sensitivity to this particular risk factor within the institution. A high proportion of publications in discontinued journals is a critical alert regarding the due diligence applied in selecting dissemination channels. It suggests that a portion of the university's scientific output is being channeled through media that may not meet international ethical or quality standards, exposing the institution to severe reputational risks and highlighting a need to reinforce information literacy to avoid 'predatory' publishing practices.

Rate of Hyper-Authored Output

With a Z-score of 2.239, the institution reaches a significant risk level, amplifying a vulnerability already present in the national system, which sits at a medium-risk Z-score of 0.622. This accentuation of a national trend is a serious concern. While extensive author lists are legitimate in 'Big Science' fields, a high rate outside these contexts can indicate author list inflation, a practice that dilutes individual accountability and transparency. This signal warrants an internal review to distinguish between necessary massive collaborations and the potential prevalence of 'honorary' or political authorship practices that compromise research integrity.

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

The institution's Z-score of 0.496 is in the medium-risk range, reflecting a similar trend to the national average of 0.371, but its higher value indicates a greater exposure to this risk. A wide positive gap, where overall impact is high but the impact of institution-led research is low, signals a potential risk to sustainability. This suggests that the university's scientific prestige may be dependent and exogenous, rather than built on its own structural capacity. This finding invites a strategic reflection on whether its excellence metrics are the result of genuine internal capabilities or a consequence of strategic positioning in collaborations where the institution does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The university's Z-score of 1.149, while within the medium-risk category, is significantly higher than the national average of 0.402, indicating a high exposure to the associated risks. Extreme individual publication volumes challenge the perceived limits of meaningful intellectual contribution. This elevated indicator serves as an alert for potential imbalances between quantity and quality. It points to risks such as coercive authorship, data fragmentation, or the assignment of authorship without real participation—dynamics that prioritize the accumulation of metrics over the integrity and substance of the scientific record.

Rate of Output in Institutional Journals

The institution demonstrates integrity synchrony with the national environment, with its Z-score of -0.268 being almost identical to the country's Z-score of -0.260. This total alignment in a very low-risk area signifies maximum scientific security in this regard. By avoiding excessive dependence on its own journals, the university mitigates potential conflicts of interest and the risk of academic endogamy. This practice ensures that its scientific production undergoes independent external peer review, which is essential for limiting bias, enhancing global visibility, and validating research through standard competitive processes.

Rate of Redundant Output

The institution displays strong institutional resilience, with a low-risk Z-score of -0.230 in stark contrast to the country's medium-risk Z-score of 0.506. This indicates that its internal control mechanisms are successfully mitigating a risk that is more prevalent at the national level. A low rate of redundant output suggests that the university's researchers are not engaging in 'salami slicing'—the practice of dividing a single study into minimal publishable units to artificially inflate productivity. This commitment to publishing complete, significant work protects the integrity of scientific evidence and avoids overburdening the peer-review system.
