National University of Tainan

EXECUTIVE SUMMARY AND STRATEGIC VISION

The National University of Tainan demonstrates an exceptionally strong scientific integrity profile, with an overall risk score of -0.652 that indicates robust governance and a culture of responsible research. The institution exhibits very low risk in seven of the nine indicators analyzed, particularly in areas such as Rate of Retracted Output, Rate of Hyperprolific Authors, and Rate of Multiple Affiliations, where it significantly outperforms national averages. This performance suggests a successful isolation from systemic risks present in the wider environment. The primary areas for continued monitoring, though still classified as low risk, are the Rate of Output in Discontinued Journals and the Rate of Redundant Output. According to SCImago Institutions Rankings data, the university's thematic strengths are most prominent in Energy, where it holds a Top 10 national ranking. This commitment to high-integrity research directly underpins the university's mission "to cultivate talents with... life literacy, and professional employability," as it ensures that its academic contributions are credible, ethical, and built on a foundation of excellence. By maintaining these high standards, the National University of Tainan not only safeguards its reputation but also guarantees that the skills and knowledge it imparts are of the highest and most responsible caliber.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -1.042, a figure that signals a near-total absence of risk in this area, especially when contrasted with the national average of 1.166. This marked difference indicates a case of preventive isolation, where the university does not replicate the risk dynamics observed in its national environment. While multiple affiliations can be legitimate, disproportionately high rates can suggest strategic "affiliation shopping" to inflate institutional credit. The university’s extremely low score demonstrates strong internal governance and clear affiliation policies, effectively preventing practices that could artificially boost its metrics and ensuring that institutional credit is earned transparently.

Rate of Retracted Output

With a Z-score of -0.569 against a national average of 0.051, the institution shows a commendable and very low rate of retractions. This performance suggests a successful disconnection from the moderate risk levels seen across the country, pointing to effective internal controls. A high rate of retractions can alert to a systemic failure in quality control or a vulnerability in the institution's integrity culture. The university's low score, however, is a positive sign of methodological rigor and responsible supervision, indicating that its pre-publication validation processes are robust and serve as a firewall against the integrity risks present in the broader scientific landscape.

Rate of Institutional Self-Citation

The institution's Z-score of -1.252 is significantly lower than the national average of -0.204, demonstrating an exemplary profile of external engagement. This low-profile consistency, well below the already low national standard, confirms that the university's research is well-integrated into the global scientific conversation. A high rate of self-citation can signal scientific isolation or "echo chambers" that inflate impact through endogamous dynamics. The university's very low rate, in contrast, is a strong indicator that its academic influence is validated by the wider international community, not just by internal validation, reflecting a healthy and outward-looking research culture.

Rate of Output in Discontinued Journals

The institution's Z-score in this area is -0.101, which, while low, is slightly higher than the national average of -0.165. This subtle difference points to an incipient vulnerability that warrants review before it escalates. A high proportion of publications in discontinued journals can be a critical alert regarding due diligence in selecting dissemination channels, exposing the institution to reputational risks associated with "predatory" or low-quality practices. Although the current level is not alarming, this signal suggests a need to reinforce information literacy among researchers to ensure institutional resources are consistently channeled toward high-quality, reputable journals.

Rate of Hyper-Authored Output

With a Z-score of -1.195, the institution demonstrates a very low incidence of hyper-authorship, a rate notably better than the national average of -0.671. This reflects a low-profile consistency and a healthy alignment with national standards of good practice. Outside of "Big Science" contexts, a high rate of hyper-authorship can indicate author list inflation or the inclusion of "honorary" authors, which dilutes individual accountability. The university's excellent score suggests a transparent and merit-based authorship culture where credit is assigned appropriately, reinforcing the integrity of its collaborative research.

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

The institution's Z-score of -0.996 is substantially lower than the national average of -0.559, indicating a very healthy and sustainable research ecosystem. This low-profile consistency shows that the impact of research led directly by the institution is commensurate with the impact of its collaborative work. A wide positive gap can signal that an institution's prestige is overly dependent on external partners rather than its own structural capacity. The university's minimal gap is a strong sign of its intellectual leadership and robust internal capabilities, demonstrating that its scientific excellence is homegrown and sustainable.

Rate of Hyperprolific Authors

The institution records an exceptionally low Z-score of -1.413, starkly contrasting with the national average of 0.005, which falls into the medium-risk category. This demonstrates a clear case of preventive isolation, where the university's internal culture actively resists national trends toward metric-driven productivity. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution and may signal risks such as coercive authorship or a focus on quantity over quality. The university’s near-absence of this phenomenon is a powerful indicator of a research environment that values substantive scientific advancement over the artificial inflation of publication counts.

Rate of Output in Institutional Journals

With a Z-score of -0.268, which is well below the national average of -0.075, the institution shows a very low reliance on its own journals for dissemination. This reflects a low-profile consistency with a national environment that also favors external publication, but the university's position is even more robust. Excessive dependence on in-house journals can create conflicts of interest and academic endogamy, potentially bypassing rigorous external peer review. The university’s minimal use of such channels underscores its commitment to global visibility and competitive validation, ensuring its research is vetted by independent international experts.

Rate of Redundant Output

The institution's Z-score of -0.332 is lower than the national average of -0.176, indicating a prudent profile in managing publication strategy. Both scores are in the low-risk category, but the university demonstrates more rigor than the national standard. A high rate of redundant output, or "salami slicing," points to the practice of fragmenting a single study into multiple minimal publications to inflate productivity, which distorts the scientific record. The university's lower rate suggests a culture that encourages the publication of coherent, significant studies, prioritizing the advancement of knowledge over the maximization of publication metrics.
