Technical University in Zvolen

EXECUTIVE SUMMARY AND STRATEGIC VISION

The Technical University in Zvolen (TUZVO) presents a dual profile in scientific integrity, combining areas of exceptional robustness with specific, significant vulnerabilities that require strategic attention. With an overall integrity score of 0.469, the institution demonstrates a solid foundation, particularly in preventing retractions, redundant publications, and the use of discontinued journals. These strengths are a testament to sound internal governance. Thematically, SCImago Institutions Rankings data confirms TUZVO's leadership in areas central to its mission, such as Energy (ranked #2 in Slovakia), Agricultural and Biological Sciences (#6), and Environmental Science (#10). However, the university's commitment to excellence within the European Higher Education Area is challenged by critical risks in its publication practices, most notably an extremely high rate of output in its own institutional journals and elevated levels of self-citation. These patterns suggest a degree of academic insularity that could undermine the external validation and global impact of its specialized research. To fully realize its mission, TUZVO is encouraged to balance its unique focus with practices that ensure broader international peer review and collaboration, thereby strengthening the credibility and reach of its important work in the forest, wood, and ecology sectors.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution exhibits a prudent approach to author affiliations, with a Z-score of -0.602, which is slightly more rigorous than the national standard of -0.546. This indicates that the university's processes for managing and reporting affiliations are well-controlled and less prone to risk than the national average. While multiple affiliations can be a legitimate outcome of collaboration, the university's contained rate suggests a low probability of strategic practices like “affiliation shopping” aimed at artificially inflating institutional credit, reflecting a commendable level of transparency in its collaborative footprint.

Rate of Retracted Output

With a Z-score of -0.475, the university shows a very low incidence of retracted publications, a performance that aligns well with the low-risk national environment (Z-score: -0.222). This near-absence of risk signals demonstrates a strong and consistent integrity culture. It suggests that the institution's quality control mechanisms prior to publication are effective and that its researchers adhere to high standards of methodological rigor, preventing the types of unintentional errors or potential malpractice that can lead to retractions. This result is indicative of a healthy and responsible research supervision system.

Rate of Institutional Self-Citation

The university displays a high exposure to risks associated with self-citation, with a Z-score of 1.380 that is notably higher than the national average of 0.950. This suggests the institution is more prone than its peers to practices that could lead to scientific isolation. While a certain level of self-citation is natural for specialized research lines, this elevated rate warns of a potential 'echo chamber' where work is validated internally without sufficient external scrutiny. This dynamic creates a risk of endogamous impact inflation, where the institution's academic influence may appear larger due to internal citation patterns rather than broad recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution demonstrates an exemplary disconnection from the risks associated with publishing in discontinued journals, with a Z-score of -0.357 in a national context where this is a medium-level risk (Z-score: 0.249). This finding indicates that the university has effectively isolated itself from a problematic dynamic observed elsewhere in the country. The very low rate suggests that its researchers exercise excellent due diligence in selecting publication venues, successfully avoiding channels that fail to meet international ethical or quality standards. This preventive stance protects the institution from severe reputational damage and shows a high degree of information literacy in its research community.

Rate of Hyper-Authored Output

With a Z-score of 0.720, the institution shows a greater propensity for hyper-authored publications compared to the national average of 0.088, indicating a higher exposure to the associated risks. Although both fall within a medium-risk band, the university's rate is significantly more pronounced. This pattern, especially if occurring outside of 'Big Science' fields, can be a signal of author list inflation, which dilutes individual accountability and transparency. It warrants a closer examination to distinguish between necessary large-scale collaborations and potential 'honorary' authorship practices that could compromise the integrity of author contributions.

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

The university effectively manages its scientific leadership impact, showing a Z-score of 0.239, which is considerably lower than the national average of 0.543. This indicates a more balanced and sustainable impact profile. While it is common for institutions to rely on external partners, a wide gap can signal that prestige is dependent and exogenous. TUZVO's moderate score suggests that it successfully moderates this risk, demonstrating that its overall impact is more closely aligned with the research it leads. This reflects a healthy internal capacity for generating high-quality science, rather than relying primarily on a strategic position in collaborations led by others.

Rate of Hyperprolific Authors

The institution maintains a very low-risk profile regarding hyperprolific authors, with a Z-score of -1.157, which is even lower than the already low-risk national context (Z-score: -0.585). This absence of extreme individual publication volumes is a strong positive signal. It suggests that the university's environment does not foster dynamics that prioritize sheer quantity over quality, such as coercive authorship or data fragmentation. The data indicates a healthy balance where researchers' outputs are credible and align with realistic expectations of meaningful intellectual contribution, reinforcing the integrity of the scientific record.

Rate of Output in Institutional Journals

The university's rate of publication in its own journals represents a critical risk, with a Z-score of 7.652. This figure dramatically amplifies a vulnerability that is only moderately present in the national system (Z-score: 0.985). Such an extreme dependence on in-house journals raises significant conflict-of-interest concerns, as the institution is acting as both judge and party in the scientific validation process. This practice points to severe academic endogamy, where research may be bypassing independent external peer review. This not only limits the global visibility and credibility of the university's output but also suggests that internal channels may be used as 'fast tracks' to inflate publication records without standard competitive validation, a practice that requires urgent review.

Rate of Redundant Output

The university shows a strong preventive isolation from the practice of redundant publication, or 'salami slicing,' with a Z-score of -0.463. This is a notable achievement, as it stands in contrast to the national environment, where this indicator presents a medium risk (Z-score: 0.244). This result indicates that the institution does not replicate the risk dynamics seen elsewhere in the country. The low bibliographic overlap between publications suggests that researchers are focused on presenting coherent, significant studies rather than artificially inflating productivity by fragmenting data into minimal publishable units. This commitment to substance over volume strengthens the scientific record and reflects high ethical standards.
