National Cheng Kung University

EXECUTIVE SUMMARY AND STRATEGIC VISION

National Cheng Kung University demonstrates a solid overall performance in scientific integrity, with a global Z-score of -0.104 indicating a risk profile that is generally well-managed and favorable. The institution's primary strengths lie in its exceptionally low rates of publication in institutional journals and its prudent avoidance of discontinued or predatory venues, showcasing a strong commitment to external validation and quality control. However, areas requiring strategic attention include the rates of multiple affiliations and retracted output, which register at a medium risk level. While the institution's performance on multiple affiliations is better than the national average, its retraction rate is slightly elevated, suggesting a need for a qualitative review of pre-publication oversight. These findings are particularly relevant given the university's prominent standing in key thematic areas, as evidenced by SCImago Institutions Rankings data placing it among the top institutions in Taiwan for Energy, Mathematics, Psychology, and Computer Science. To fully align with a mission of academic excellence and social responsibility, it is crucial to address these integrity vulnerabilities, as any perception of systemic failure in quality control or strategic inflation of credit could undermine the credibility of its otherwise outstanding research. A proactive approach to monitoring these specific indicators will reinforce the university's reputation and ensure its leadership is built on a foundation of unimpeachable scientific practice.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

With a Z-score of 0.304, the institution presents a medium risk level for this indicator, which is notably lower than the national average of 1.166. This suggests a differentiated management approach, where the university successfully moderates a risk that appears to be more common and pronounced across the country. While multiple affiliations are often a legitimate result of collaboration, disproportionately high rates can signal strategic attempts to inflate institutional credit. National Cheng Kung University's ability to maintain a lower rate than its national peers, despite both being in the medium-risk category, indicates more effective governance or clearer policies regarding how affiliations are reported, thereby mitigating the risk of "affiliation shopping" more successfully than its environment.

Rate of Retracted Output

The institution's Z-score of 0.136 places it in the medium risk category, a level it shares with the national context (0.051). However, the university's score is higher than the national average, indicating a greater exposure to this particular risk. Retractions are complex events, but a rate significantly higher than the norm suggests that quality control mechanisms prior to publication may be failing systemically. This elevated signal warns of a potential vulnerability in the institution's integrity culture, pointing to possible recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management to protect its scientific reputation.

Rate of Institutional Self-Citation

The university's Z-score of -0.112 is in the low-risk range, slightly higher than the national average of -0.204. This minor difference points to an incipient vulnerability that warrants review before it escalates. A certain level of self-citation is natural and reflects the continuity of research lines. However, the university's slightly more pronounced signal, though still low, suggests a need to ensure its academic influence is consistently validated by the global community rather than by internal dynamics. Monitoring this trend is important to prevent the formation of 'echo chambers' where the institution's work might risk being validated without sufficient external scrutiny.

Rate of Output in Discontinued Journals

National Cheng Kung University demonstrates a prudent profile in its selection of publication venues, with a low-risk Z-score of -0.285 that is significantly better than the national average of -0.165. This indicates that the institution manages its processes with more rigor than the national standard. A high proportion of publications in discontinued journals constitutes a critical alert regarding due diligence, often exposing an institution to reputational risks associated with 'predatory' practices. The university's strong performance here shows it has effective mechanisms for information literacy, successfully guiding its researchers away from low-quality channels and protecting its scientific output.

Rate of Hyper-Authored Output

The institution's risk level for hyper-authored output is low (Z-score: -0.648) and aligns almost perfectly with the national standard (Z-score: -0.671), indicating a state of statistical normality. The rate of extensive author lists is as expected for its context and size. In many scientific fields, large author lists are a legitimate reflection of massive, necessary collaboration. The university's alignment with the national norm suggests that its practices are consistent with established disciplinary conventions rather than signaling potential issues like author list inflation or the dilution of individual accountability through 'honorary' authorships.

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

With a Z-score of -0.379, the university's risk in this area is low but slightly higher than the national average of -0.559, signaling an incipient vulnerability. This indicator measures the dependency on external partners for impact; a large positive gap suggests that scientific prestige may be more exogenous than structural. While the university's score is well within the low-risk range, the slight elevation compared to its national peers invites reflection on strengthening internal capacity. It serves as a forward-looking signal to ensure that its growing reputation for excellence is increasingly driven by research where the institution exercises direct intellectual leadership.

Rate of Hyperprolific Authors

The university displays significant institutional resilience in this area, maintaining a low-risk Z-score of -0.293 while the national context shows a medium-level risk (0.005). This demonstrates that the university's internal control mechanisms appear to be successfully mitigating a systemic risk present in 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.' The university's ability to maintain a low rate in a higher-risk environment suggests a culture that effectively promotes a healthy balance between productivity and the integrity of the scientific record.

Rate of Output in Institutional Journals

The university's performance on this indicator is exemplary, with a very low-risk Z-score of -0.145, which is superior to the already low national standard (-0.075). This low-profile consistency, where the absence of risk signals aligns with and improves upon the national norm, is a strong positive sign. Excessive dependence on in-house journals can raise conflicts of interest and lead to academic endogamy by bypassing independent external peer review. The university's near-total avoidance of this practice confirms its commitment to global standards of validation, enhancing the credibility and visibility of its research output.

Rate of Redundant Output

With a low-risk Z-score of -0.359, the university exhibits a prudent profile that is notably more rigorous than the national standard (-0.176). This indicates a stronger institutional commitment to preventing data fragmentation. A high rate of bibliographic overlap between publications can be a sign of 'salami slicing,' a practice used to artificially inflate productivity by dividing a single study into minimal publishable units. The university's superior performance suggests that its authors and oversight bodies prioritize the publication of significant, coherent new knowledge over sheer volume, thereby strengthening the quality and integrity of its scientific contributions.
