National Central University

EXECUTIVE SUMMARY AND STRATEGIC VISION

National Central University presents a robust scientific integrity profile, with an overall risk score of -0.231 that indicates a performance well-aligned with global standards of good practice. The institution demonstrates significant strengths in its post-publication quality control, evidenced by a very low rate of retracted output, and a clear commitment to external validation, reflected in minimal reliance on institutional journals and a near-absence of redundant publications. These strengths are foundational. However, areas requiring strategic attention include a moderate tendency towards institutional self-citation, hyper-authored publications, and a notable gap between its overall impact and the impact of research where it holds intellectual leadership. According to SCImago Institutions Rankings data, the university's academic prowess is particularly prominent in fields such as Earth and Planetary Sciences, Economics, Econometrics and Finance, Social Sciences, and Business, Management and Accounting, where it ranks among the top institutions in Taiwan. The identified risks, particularly those related to insular validation and impact dependency, could subtly undermine the university's mission to pursue "Academic Excellence" and "Lead Innovation." True leadership requires not just participation but intellectual ownership and broad external validation. By addressing these moderate-risk indicators, National Central University can more fully align its operational practices with its ambitious vision, ensuring its reputation for excellence is built on a foundation of unimpeachable integrity and sustainable, internally-driven innovation.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 0.159 is notably lower than the national average of 1.166. This suggests a pattern of differentiated management, where the university moderates a risk that appears more common across the country. While multiple affiliations can be a legitimate outcome of collaboration, the institution's more controlled rate indicates it is less exposed than its national peers to practices that could be perceived as strategic "affiliation shopping" to inflate institutional credit. This prudent approach helps maintain clarity and transparency in attributing research contributions.

Rate of Retracted Output

With a Z-score of -0.475, the institution demonstrates a near-total absence of this risk signal, in sharp contrast to the national average of 0.051. This positive result points to a state of preventive isolation, where the university does not replicate the risk dynamics observed in its environment. A high rate of retractions can suggest systemic failures in pre-publication quality control. The university's exceptional performance here indicates that its integrity culture and methodological rigor are robust, effectively preventing the types of recurring malpractice or error that can damage institutional reputation and require later correction.

Rate of Institutional Self-Citation

The institution exhibits a Z-score of 0.189, which represents a moderate deviation from the national average of -0.204. This divergence indicates that the university shows a greater sensitivity to this risk factor than its peers. While some self-citation is natural, this elevated rate warns of a potential 'echo chamber' where work is validated internally without sufficient external scrutiny. This dynamic could lead to an endogamous inflation of impact, suggesting that the institution's academic influence may be oversized by internal citation practices rather than by recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.228 is slightly better than the national average of -0.165, reflecting a prudent profile in its publication strategy. This indicates that the university manages its processes with more rigor than the national standard. A high proportion of publications in discontinued journals can be a critical alert regarding due diligence. The institution's low score suggests its researchers are effectively avoiding channels that fail to meet international ethical or quality standards, thereby protecting its resources and reputation from predatory or low-quality practices.

Rate of Hyper-Authored Output

With a Z-score of 0.969, the institution shows a moderate deviation from the national average of -0.671. This discrepancy suggests a greater sensitivity to risk factors related to authorship. A high rate of hyper-authorship can signal an inflation of author lists, which dilutes individual accountability and transparency. The university's score serves as a signal to review authorship practices to distinguish between necessary large-scale collaboration and potential 'honorary' or political authorship, ensuring that credit is assigned appropriately.

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

The institution's Z-score of 0.101 marks a moderate deviation from the national average of -0.559. This gap suggests that the university is more sensitive than its peers to a dependency on external collaborations for its citation impact. A wide positive gap, where overall impact is high but the impact of institution-led research is low, signals a sustainability risk. This value invites reflection on whether the university's prestige is primarily derived from its own structural capacity or from strategic positioning in collaborations where it does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The institution's Z-score of -0.657 is significantly lower than the national average of 0.005, demonstrating strong institutional resilience. This performance indicates that internal control mechanisms are effectively mitigating systemic risks that may be more prevalent in the country. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution. The university's low score in this area suggests a healthy balance between quantity and quality, successfully avoiding risks such as coercive authorship or the assignment of credit without real participation.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution shows a near-absence of this risk signal, a finding consistent with the low-risk national average of -0.075. This low-profile consistency demonstrates a strong alignment with national standards of good practice. Excessive dependence on in-house journals can create conflicts of interest and academic endogamy. The university's very low rate indicates a clear commitment to independent, external peer review, which enhances the global visibility and competitive validation of its research output.

Rate of Redundant Output

The institution's Z-score of -0.592 is exceptionally low, reinforcing the low-risk environment seen in the national average of -0.176. This result demonstrates low-profile consistency, where the absence of risk signals aligns perfectly with the national standard. A high rate of redundant output, or 'salami slicing,' indicates the artificial fragmentation of studies to inflate productivity. The university's excellent score confirms its adherence to ethical publication standards that prioritize significant new knowledge over volume, thereby strengthening the integrity of the scientific record.
