University of Macau

EXECUTIVE SUMMARY AND STRATEGIC VISION

The University of Macau demonstrates a robust and well-managed scientific integrity profile, reflected in its overall risk score of -0.103. This indicates a strong alignment with international best practices and a low overall exposure to research integrity risks. The institution's primary strengths lie in its exceptional control over practices such as institutional self-citation, publication in discontinued journals, and redundant publication, where it outperforms even the low-risk national averages. These results are consistent with the university's high academic standing, as evidenced by its leadership positions within Macao and strong regional rankings in key thematic areas like Pharmacology, Toxicology and Pharmaceutics; Agricultural and Biological Sciences; Computer Science; and Engineering, according to SCImago Institutions Rankings data. However, areas requiring strategic attention include the rate of hyperprolific authors and multiple affiliations, which present a medium level of risk. These vulnerabilities, if unaddressed, could subtly undermine the institution's mission to foster the "advancement of scholarship," as a focus on publication volume or affiliation metrics can conflict with the pursuit of genuine excellence and intellectual leadership. To further solidify its reputation as a leading institution, it is recommended that the University of Macau maintain its excellent control mechanisms while developing targeted policies to address authorship and affiliation practices, ensuring that its impressive growth is built upon a foundation of unimpeachable scientific integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 0.379 is notably lower than the national average of 0.994, indicating a more controlled approach to a practice that is common within its national context. This suggests that the University of Macau has implemented differentiated management strategies that effectively moderate the risks associated with multiple affiliations. While such affiliations are often a legitimate result of collaboration or researcher mobility, disproportionately high rates can signal strategic attempts to inflate institutional credit or "affiliation shopping." The university's ability to maintain a lower rate than its peers demonstrates a capacity to manage collaborative engagement without falling into the potential pitfall of over-attributing credit, a risk more prevalent at the national level.

Rate of Retracted Output

With a Z-score of -0.230, which is below the national average of -0.149, the institution exhibits a prudent profile regarding retracted publications. This performance suggests that its internal quality control and supervision mechanisms are managed with more rigor than the national standard. Retractions are complex events, and while some signify responsible error correction, a consistently low rate points to a healthy integrity culture. The university's score indicates that its pre-publication processes are effective in minimizing the systemic failures, potential recurring malpractice, or lack of methodological rigor that can lead to a higher incidence of retractions, thereby safeguarding its scientific record.

Rate of Institutional Self-Citation

The university's Z-score of -0.848 is significantly below the national Z-score of -0.588, demonstrating an exceptionally low rate of institutional self-citation. This absence of risk signals aligns with the low-risk national environment, but the university's performance is even stronger, reflecting a low-profile consistency. While a certain level of self-citation is natural, the university's very low rate confirms that its academic influence is validated by broad external scrutiny rather than through internal 'echo chambers.' This effectively mitigates any risk of endogamous impact inflation and shows that its scholarly recognition is driven by the wider global community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.381 is markedly lower than the national Z-score of -0.053, showcasing a very low and well-managed risk profile in this area. This performance is consistent with the low-risk national standard but highlights the university's superior due diligence in selecting publication venues. A high proportion of output in discontinued journals can be a critical alert, exposing an institution to severe reputational risks and suggesting a failure to avoid 'predatory' or low-quality practices. The university's excellent score demonstrates a strong commitment to information literacy and a policy of channeling its scientific production through reputable media that meet international ethical and quality standards.

Rate of Hyper-Authored Output

At -0.653, the institution's Z-score is slightly higher than the national average of -0.732, signaling an incipient vulnerability that warrants review before it escalates. Although the overall risk level is low, this subtle deviation from the national norm suggests the university is beginning to show signals in this area. While extensive author lists are legitimate in 'Big Science,' a rising trend outside these contexts can indicate author list inflation, which dilutes individual accountability and transparency. This minor signal serves as a prompt to proactively ensure that authorship practices remain rigorous and clearly distinguish between necessary massive collaboration and potentially 'honorary' attributions.

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

The university's Z-score of -0.954 indicates a minimal risk, yet it is slightly higher than the national average of -1.058. In a national environment that is virtually inert in this regard, this small deviation represents residual noise, suggesting the university is the first to show any signal, however small. A wide positive gap can signal a sustainability risk where prestige is dependent on external partners rather than internal capacity. While the university's score is excellent and confirms strong intellectual leadership, this minor difference from the national baseline is a data point for monitoring the long-term development of endogenous research capacity to ensure its scientific prestige remains structural.

Rate of Hyperprolific Authors

With a Z-score of 1.936, the university demonstrates a higher exposure to this risk indicator compared to the national average of 1.302. This suggests the institution is more prone than its peers to hosting authors with extreme publication volumes. While high productivity can evidence leadership, publication rates exceeding 50 articles a year often challenge the limits of meaningful intellectual contribution. This elevated indicator serves as an alert for potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of authorship without real participation. It highlights a need to review internal incentive structures to ensure they prioritize the integrity of the scientific record over raw metrics.

Rate of Output in Institutional Journals

The university's Z-score of -0.268 is identical to the national average, demonstrating perfect integrity synchrony and total alignment with an environment of maximum scientific security. This score confirms a complete absence of risk related to academic endogamy. While in-house journals can be valuable for local dissemination, excessive dependence on them raises conflicts of interest. The university's very low and synchronized score affirms that its scientific production consistently undergoes independent external peer review, ensuring global visibility and avoiding the use of internal channels as 'fast tracks' to inflate CVs without standard competitive validation.

Rate of Redundant Output

The university's Z-score of -0.796 is significantly lower than the already low national average of -0.614, indicating a state of total operational silence for this risk. This exceptional performance demonstrates a complete absence of signals related to data fragmentation, even when compared to a low-risk national context. Massive and recurring bibliographic overlap between publications can indicate 'salami slicing'—the practice of dividing a study into minimal units to artificially inflate productivity. The university's score reflects a strong institutional culture that prioritizes the publication of significant new knowledge over the inflation of output volume, thereby upholding the integrity of the scientific evidence base.
