VNU University of Science

EXECUTIVE SUMMARY AND STRATEGIC VISION

VNU University of Science demonstrates a complex scientific integrity profile, with an overall risk score of 0.267 that reflects a combination of commendable strengths and significant vulnerabilities. The institution excels in areas requiring strict internal governance, showing very low risk in the Rate of Hyperprolific Authors and the Rate of Output in Institutional Journals, and effectively mitigates national trends of publishing in discontinued journals. However, these strengths are counterbalanced by notable weaknesses, particularly a significant-risk level in the Rate of Retracted Output, which is a critical concern. Medium-risk signals in Multiple Affiliations, Institutional Self-Citation, and Hyper-Authorship further suggest that institutional practices may be amplifying certain systemic vulnerabilities present in the national research environment. According to SCImago Institutions Rankings data, the university holds strong national positions in key thematic areas, including Medicine (ranked 4th in Viet Nam), Physics and Astronomy (10th), and Environmental Science (11th). While the institution's specific mission was not available for this analysis, the identified risks, especially concerning retractions and authorship, could undermine foundational academic values such as excellence and social responsibility. Addressing these vulnerabilities proactively is essential to safeguard the integrity that underpins its thematic strengths and to ensure its research contributions are both impactful and trustworthy.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 1.067 indicates a moderate deviation from the national standard, which sits at a low-risk -0.035. This suggests that the university is more sensitive than its national peers to factors that drive multiple affiliations. While such affiliations are often a legitimate result of researcher mobility or partnerships, a disproportionately high rate can signal strategic attempts to inflate institutional credit or engage in “affiliation shopping.” The divergence from the national norm warrants a review to ensure that all declared affiliations correspond to substantive collaborative work and do not merely serve to artificially boost institutional metrics.

Rate of Retracted Output

With a Z-score of 0.943, the institution registers a significant risk level for retracted publications, accentuating a vulnerability already present in the national system (Z-score 0.749). This elevated rate suggests that the university is amplifying a concerning national trend. Retractions are complex, but a rate significantly higher than the average alerts to a potential systemic failure in pre-publication quality control mechanisms. This finding moves beyond individual cases to indicate a possible vulnerability in the institution's integrity culture, pointing to recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management to prevent further reputational damage.

Rate of Institutional Self-Citation

Both the institution (Z-score 0.387) and the country (Z-score 0.192) exhibit a medium risk for this indicator, but the university's score is notably higher, indicating greater exposure to this behavior than its environment average. A certain level of self-citation is natural, reflecting the continuity of research lines. However, this disproportionately high rate can signal concerning scientific isolation or 'echo chambers' where work is validated without sufficient external scrutiny. This value warns of a potential for endogamous impact inflation, suggesting that the institution's academic influence may be oversized by internal dynamics rather than by recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution demonstrates notable institutional resilience, with a low-risk Z-score of -0.215 that stands in positive contrast to the country's medium-risk average of 1.127. This suggests that internal control mechanisms are effectively mitigating a systemic risk prevalent at the national level. While the broader environment shows a tendency to publish in channels that may not meet international ethical or quality standards, the university appears to be successfully guiding its researchers toward more reliable and reputable journals. This proactive management helps avoid the severe reputational risks associated with 'predatory' or low-quality publishing practices.

Rate of Hyper-Authored Output

The institution's Z-score of 0.202 (medium risk) represents a moderate deviation from the low-risk national average of -0.822. This indicates a greater institutional sensitivity to factors that encourage hyper-authorship compared to its peers. When this pattern appears outside 'Big Science' contexts where extensive author lists are standard, it can signal author list inflation, which dilutes individual accountability and transparency. This indicator serves as a signal to distinguish between necessary massive collaboration and potentially inappropriate 'honorary' or political authorship practices that may be occurring more frequently at the institution.

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

With a Z-score of 0.281, the institution presents a medium-risk gap, deviating moderately from the low-risk national trend (-0.112). This suggests a greater sensitivity to risks associated with collaborative dependency. A very wide positive gap—where global impact is high but the impact of research led by the institution itself is low—signals a sustainability risk. This value suggests that the institution's scientific prestige may be more dependent and exogenous than is typical for the country, inviting reflection on whether its excellence metrics result from genuine internal capacity or from strategic positioning in collaborations where it does not exercise primary intellectual leadership.

Rate of Hyperprolific Authors

The institution exhibits a very strong profile in this area, with a Z-score of -0.985 that signifies a very low risk, performing even better than the low-risk national average (-0.501). This demonstrates low-profile consistency, where the absence of risk signals aligns with and surpasses the national standard. The data suggests that the institution fosters a research culture that prioritizes quality over sheer volume, effectively avoiding the pressures that can lead to extreme individual publication counts and their associated risks, such as coercive authorship or the assignment of credit without real participation.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is identical to the national average, reflecting a state of integrity synchrony and total alignment with an environment of maximum scientific security on this metric. Both the university and the country operate at a very low risk level. This indicates that the institution avoids excessive dependence on its in-house journals, thus mitigating potential conflicts of interest and academic endogamy. By ensuring its scientific production undergoes independent external peer review, the institution reinforces its commitment to global visibility and competitive validation.

Rate of Redundant Output

While both the institution (Z-score 0.046) and the country (Z-score 0.313) show a medium risk for redundant output, the institution's score is substantially lower, pointing to differentiated management of this issue. This suggests the university is more effectively moderating a risk that appears common at the national level. Although the risk of 'salami slicing'—dividing a study into minimal publishable units to inflate productivity—is present, the institution demonstrates better control. This more measured approach helps preserve the integrity of the scientific evidence base and avoids overburdening the peer review system with fragmented contributions.
