The University of Nis demonstrates a solid overall performance with a score of 0.938, reflecting a profile with significant strengths in research integrity alongside specific, critical areas requiring immediate attention. The institution exhibits exemplary control over authorship practices, as evidenced by very low risks in multiple affiliations and hyperprolific authors, and shows notable resilience by maintaining low-risk levels in hyper-authorship and impact dependency, contrasting with higher national averages. According to SCImago Institutions Rankings data, the university's strongest thematic areas nationally include Environmental Science, Pharmacology, Toxicology and Pharmaceutics, and Psychology. However, this profile of excellence is challenged by a significant risk in retracted output and elevated exposure to questionable publication practices, including high rates of output in institutional journals and discontinued journals. These vulnerabilities directly contradict the institutional mission of achieving the "highest quality standards," as they suggest systemic weaknesses in quality assurance and peer review that could undermine its integration into the European higher education area. To secure its strategic vision, the University of Nis should leverage its robust governance in authorship to implement stringent quality control mechanisms and promote a culture of transparency that addresses these publication-related risks head-on.
The institution presents a Z-score of -1.026, a value indicating an even lower risk profile than the national average of -0.865. This demonstrates a state of total operational silence regarding this indicator, with an absence of risk signals that is even more pronounced than in the already secure national context. While multiple affiliations can be a legitimate outcome of academic collaboration, the university's exceptionally low rate suggests its affiliation policies are remarkably clear and transparent, effectively preventing any strategic misuse aimed at artificially inflating institutional credit or engaging in “affiliation shopping.” This reflects a robust and unambiguous administrative framework governing researcher affiliations.
With a Z-score of 2.606, the institution displays a significant risk level that starkly contrasts with the national average of 0.016. This finding suggests that the university is not only participating in but amplifying a vulnerability present in the national system. Retractions are complex events, but a rate this far above the norm is a critical alert that pre-publication quality control mechanisms may be failing systemically. This high Z-score points to a potential vulnerability in the institution's integrity culture, indicating possible recurring malpractice or a lack of methodological rigor that requires an immediate and thorough qualitative verification by the administration to safeguard its scientific reputation.
The university's Z-score of 0.841 is notably higher than the national average of 0.426, indicating a high level of exposure to this risk factor. Although a certain degree of self-citation is natural, this heightened rate suggests the institution is more prone than its national peers to operating within scientific 'echo chambers.' This pattern signals a potential for endogamous impact inflation, where the institution's academic influence might be disproportionately validated by internal dynamics rather than broader recognition from the global scientific community, potentially creating a risk of scientific isolation.
The institution's Z-score of 0.179 is higher than the national average of 0.056, revealing that it is more exposed to this risk than its peers. This elevated rate is a critical alert regarding the due diligence applied in selecting dissemination channels. It indicates that a portion of the university's scientific production is being channeled through media that may not meet international ethical or quality standards. This practice exposes the institution to severe reputational risks and suggests an urgent need to enhance information literacy among researchers to avoid channeling valuable resources and research into 'predatory' or low-quality publications.
The institution maintains a low-risk Z-score of -0.867, which is significantly better than the national average of 0.135. This demonstrates strong institutional resilience, as internal control mechanisms appear to be successfully mitigating the systemic risks observed at the country level. While extensive author lists are legitimate in 'Big Science,' their appearance in other fields can signal author list inflation. The university's favorable score indicates that it effectively distinguishes between necessary massive collaboration and questionable 'honorary' authorship, thereby upholding standards of individual accountability and transparency.
With a Z-score of -0.690, the institution shows a healthy, low-risk profile, contrasting sharply with the national average of 1.204, which signals a systemic risk. This result demonstrates exceptional institutional resilience, acting as a safeguard against the national trend of impact dependency. A wide positive gap can suggest that prestige is reliant on external partners rather than internal capacity. The university's negative score, however, indicates that its scientific prestige is structurally sound and driven by its own intellectual leadership, reflecting a sustainable and autonomous research ecosystem.
The institution's Z-score of -1.010 is well within the very low-risk category, aligning with and even improving upon the low-risk national standard of -0.382. This low-profile consistency signals a healthy research environment where the focus remains on quality over sheer quantity. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution and point to risks like coercive authorship. The absence of such signals at the university indicates a well-balanced academic culture that prioritizes the integrity of the scientific record over the inflation of productivity metrics.
The university's Z-score of 3.518 is exceptionally high, far exceeding the national average of 0.912 and indicating a significant exposure to this risk. This result warns of a pronounced tendency towards academic endogamy, where scientific production may be bypassing independent external peer review. Such a heavy reliance on in-house journals raises potential conflicts of interest, as the institution acts as both judge and party. This practice limits the global visibility and competitive validation of its research and may suggest the use of internal channels as 'fast tracks' to inflate publication records without undergoing standard, rigorous scrutiny.
The institution presents a Z-score of 0.160, indicating a moderate deviation from the national context, which has a low-risk score of -0.120. This difference suggests that the university shows a greater sensitivity to risk factors that encourage data fragmentation compared to its national peers. A high value in this indicator alerts to the practice of 'salami slicing,' where a single study is divided into minimal publishable units to artificially inflate an author's or institution's productivity. This behavior not only overburdens the peer-review system but also distorts the scientific evidence base by prioritizing publication volume over the generation of significant new knowledge.
