Tshwane University of Technology

EXECUTIVE SUMMARY AND STRATEGIC VISION

Tshwane University of Technology demonstrates a robust scientific profile, marked by a commendable overall integrity score of 0.187. The institution exhibits significant strengths in maintaining very low-risk levels for hyper-authored output and publications in its own journals, alongside prudent management of self-citation, impact dependency, and redundant publications. However, areas requiring strategic attention include a high exposure to retractions and hyperprolific authorship, and a moderate deviation in publishing in discontinued journals. These findings are contextualized by the university's outstanding performance in several key research areas, as evidenced by SCImago Institutions Rankings data, where it ranks among the top 10 nationally in fields such as Chemistry, Earth and Planetary Sciences, Pharmacology, and Biochemistry, Genetics and Molecular Biology. The identified integrity risks, particularly those related to publication quality and authorship practices, could potentially undermine the institution's mission to "advance social and economic transformation through impactful research and quality learning experiences." Upholding the highest standards of scientific integrity is fundamental to ensuring that research is truly "impactful" and that the university's reputation for "quality" remains unblemished. We recommend a proactive review of authorship guidelines and publication vetting processes to fortify these areas, thereby ensuring that operational practices fully align with the institution's core mission of excellence and social responsibility.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of 0.222, which is considerably lower than the national average of 1.402. This indicates a differentiated management approach, where the university successfully moderates the risk of excessive multiple affiliations, a practice more common at the national level. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, the institution's controlled rate suggests it is effectively avoiding strategic attempts to inflate institutional credit or "affiliation shopping." This reflects a stable and well-defined collaborative framework that prioritizes genuine partnership over metric augmentation.

Rate of Retracted Output

With a Z-score of 0.474, the institution shows a higher rate of retracted publications compared to the national average of 0.050. This suggests a high exposure to the underlying causes of retractions. Retractions are complex events, but a rate significantly higher than the national norm serves as an alert that pre-publication quality control mechanisms may be failing systemically. This vulnerability in the institution's integrity culture could point to recurring malpractice or a lack of methodological rigor, warranting immediate qualitative verification by management to safeguard its scientific reputation.

Rate of Institutional Self-Citation

The institution's Z-score of -0.239 is well below the national average of 0.048, which sits in the medium-risk category. This demonstrates strong institutional resilience, as control mechanisms appear to successfully mitigate the systemic risks of academic insularity observed in the country. A certain level of self-citation is natural, but the university's low rate confirms that its research is not confined to an 'echo chamber' and is receiving sufficient external scrutiny. This practice prevents endogamous impact inflation, ensuring that the institution's academic influence is genuinely recognized by the global community.

Rate of Output in Discontinued Journals

The institution's Z-score of 0.084 for publications in discontinued journals represents a moderate deviation from the national average of -0.151. This suggests the university shows a greater sensitivity to this risk factor than its national peers. A high proportion of output in such journals is a critical alert regarding due diligence in selecting dissemination channels. The current score indicates that a portion of scientific production is being channeled through media that may not meet international ethical or quality standards, exposing the institution to reputational risks and highlighting a need to improve information literacy to avoid 'predatory' practices.

Rate of Hyper-Authored Output

With a Z-score of -1.224, far below the national average of -0.079, the institution shows a near-total absence of risk signals related to hyper-authorship. This low-profile consistency aligns with the national standard, which is also low-risk, but the university's performance is even stronger. This result indicates that authorship practices are well-governed, effectively preventing author list inflation and ensuring that individual accountability and transparency are maintained. It reflects a culture that values genuine contribution over the dilution of responsibility often seen in honorary or political authorship.

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

The institution records a Z-score of -0.654, contrasting sharply with the national average of 0.624. This result signals strong institutional resilience, as the university avoids the dependency on external partners for impact that is more prevalent nationally. A wide positive gap can suggest that scientific prestige is exogenous and not structural. The institution's negative score, however, indicates that the impact of research it leads is robust, reflecting a high degree of internal capacity and intellectual leadership rather than a strategic reliance on collaborations where it plays a secondary role.

Rate of Hyperprolific Authors

The institution's Z-score of 1.570 is significantly higher than the national average of 0.086, indicating high exposure to risks associated with hyperprolific authors. While high productivity can reflect leadership, extreme individual publication volumes challenge the limits of meaningful intellectual contribution. This elevated indicator alerts to potential imbalances between quantity and quality, pointing to risks such as coercive authorship or the assignment of authorship without real participation. These are dynamics that prioritize metrics over the integrity of the scientific record and require careful review.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution demonstrates an absence of risk signals for this indicator, performing even better than the already low national average of -0.153. This state of total operational silence shows that the university is not reliant on its own journals for publication. While in-house journals can be valuable, excessive use raises conflict-of-interest concerns. The institution's extremely low rate confirms that its scientific production is consistently subjected to independent external peer review, thereby maximizing global visibility and avoiding the use of internal channels as 'fast tracks' to inflate productivity without standard competitive validation.

Rate of Redundant Output

The institution has a Z-score of -0.361, which is notably lower than the national average of -0.012. This prudent profile suggests that the university manages its publication processes with more rigor than the national standard. Massive bibliographic overlap between publications often indicates data fragmentation or 'salami slicing' to artificially inflate productivity. The institution's low score indicates that its researchers are largely avoiding this practice, instead prioritizing the publication of significant new knowledge over the distortion of scientific evidence for metric gain.
