Ho Chi Minh City University of Transport

EXECUTIVE SUMMARY AND STRATEGIC VISION

Ho Chi Minh City University of Transport presents a profile of notable strengths in scientific integrity, with an overall risk score of 2.027 reflecting a generally controlled environment. The institution demonstrates exemplary practices in several key areas, particularly in managing authorship norms, ensuring intellectual leadership in its collaborations, and avoiding conflicts of interest with institutional journals. These strengths provide a solid foundation for its research activities. However, this positive outlook is contrasted by significant vulnerabilities, most critically a high rate of retracted publications, alongside concerning levels of institutional self-citation and output in discontinued journals. These risks directly challenge the university's mission to serve national modernization and international integration through credible scientific research and technology transfer. The institution's strong national standing, with SCImago Institutions Rankings placing it in the top 5 for Energy and top 10 for Engineering, Computer Science, and Environmental Science, underscores the importance of addressing these integrity gaps to protect its reputation and ensure its research excellence translates into reliable societal impact. By focusing on strengthening pre-publication quality controls and enhancing author education on publication ethics, the university can leverage its core strengths to mitigate these risks and fully align its practices with its ambitious mission.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution demonstrates a prudent profile with a Z-score of -0.671, which is significantly lower than the national average of -0.035. This indicates that the university manages its affiliation processes with more rigor than the national standard. While multiple affiliations can be a legitimate outcome of collaboration, the institution’s controlled rate suggests a healthy and transparent approach, effectively avoiding strategic attempts to inflate institutional credit or engage in “affiliation shopping,” thereby ensuring that credit for research output is assigned appropriately.

Rate of Retracted Output

With a Z-score of 6.588, the institution shows a critical level of risk that significantly amplifies the vulnerabilities already present in the national system, where the average score is 0.749. This severe discrepancy suggests that the institution's pre-publication quality control mechanisms may be failing systemically. A rate this far above the global average is a major alert to a vulnerability in the institution's integrity culture. It points towards possible recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management to prevent further damage to its scientific reputation.

Rate of Institutional Self-Citation

The institution’s Z-score of 1.976 indicates a higher exposure to this risk compared to the national average of 0.192. This suggests the center is more prone to developing concerning citation patterns than its peers. While a certain level of self-citation is natural, this disproportionately high rate can signal the formation of scientific 'echo chambers' where work is validated internally without sufficient external scrutiny. This value warns of a potential for endogamous impact inflation, where the institution's academic influence might be oversized by internal dynamics rather than by recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution shows high exposure in this area with a Z-score of 1.458, exceeding the national average of 1.127. This indicates a greater tendency than its peers to publish in channels that do not meet international standards. A high proportion of output in such journals is a critical alert regarding the due diligence applied in selecting dissemination venues. It suggests that a significant portion of scientific production is being channeled through media of questionable quality, exposing the institution to severe reputational risks and signaling an urgent need for information literacy to avoid wasting resources on 'predatory' or low-quality practices.

Rate of Hyper-Authored Output

The institution's Z-score of -1.246 is well below the national average of -0.822, demonstrating a low-profile consistency where the absence of risk signals aligns perfectly with the national standard. This excellent result indicates a healthy authorship culture that avoids the inflation of author lists. The data suggests that the institution successfully maintains transparency and individual accountability in its publications, steering clear of 'honorary' or political authorship practices and ensuring that credit is awarded based on meaningful contributions.

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

With a Z-score of -1.599, significantly lower than the national average of -0.112, the institution shows an absence of risk signals that is consistent with the national environment. This very low score is a positive indicator of scientific autonomy and sustainability. It demonstrates that the institution's scientific prestige is structural and derived from its own internal capacity. The impact of its research is driven by projects where it exercises intellectual leadership, rather than being dependent on external partners, reflecting a robust and self-sufficient research ecosystem.

Rate of Hyperprolific Authors

The institution maintains a prudent profile with a Z-score of -0.847, which is lower than the national average of -0.501. This suggests that the university manages research productivity with more rigor than the national standard. The controlled rate of hyperprolific authors indicates a healthy balance between quantity and quality of publications. It suggests the institution fosters an environment that discourages practices like coercive authorship or 'salami slicing,' prioritizing the integrity of the scientific record over the simple inflation of publication metrics.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is identical to the national average, indicating perfect integrity synchrony and total alignment with an environment of maximum scientific security. This result confirms the absence of any risk of academic endogamy. It shows that the university does not depend on its own journals for publication, ensuring its research undergoes independent external peer review. This practice enhances the global visibility and credibility of its scientific output, demonstrating a commitment to competitive, international standards of validation.

Rate of Redundant Output

With a Z-score of -0.386, the institution demonstrates notable resilience, as it effectively mitigates a risk that is present at a medium level in the national context (country score of 0.313). This suggests that the institution's internal control mechanisms are working well to prevent data fragmentation. By maintaining a low rate of redundant output, the university discourages the practice of 'salami slicing'—dividing a single study into minimal units to inflate productivity—thereby promoting the publication of significant, coherent knowledge and upholding the integrity of the scientific evidence base.
