Universite de Guyane

EXECUTIVE SUMMARY AND STRATEGIC VISION

The Université de Guyane demonstrates a robust scientific integrity profile, with an overall risk score of -0.247 indicating a general alignment with best practices. The institution exhibits significant strengths, particularly in its minimal rates of retracted output, publication in discontinued journals, hyperprolific authorship, and use of institutional journals, all of which signal strong internal quality controls. However, this solid foundation is contrasted by two key vulnerabilities: a significant rate of hyper-authored output and a medium-level gap between its total scientific impact and the impact of research where it holds a leadership role. According to SCImago Institutions Rankings data, the university holds a leadership position in French Guiana, ranking first in critical areas such as Agricultural and Biological Sciences, Biochemistry, Genetics and Molecular Biology, and Environmental Science. These thematic strengths are central to its mission to advance knowledge for societal development. Yet, the identified risks of potential authorship inflation and dependency on external partners for impact could challenge its commitment to a "culture of high standards." Addressing these specific vulnerabilities is crucial to ensure that the university's recognized thematic excellence is built on a sustainable and fully autonomous foundation, thereby reinforcing its role as a key driver of research and creation in the region.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of -0.267 is identical to the national average, reflecting a risk level that is low and perfectly aligned with its operational context. This alignment suggests that the university's collaborative practices are in step with national norms, exhibiting a standard and expected level of engagement. While multiple affiliations can sometimes signal attempts to inflate institutional credit, the low score here indicates that the observed rate is more likely a legitimate result of researcher mobility and healthy partnerships, posing no immediate risk to scientific integrity.

Rate of Retracted Output

With a Z-score of -0.493, which is perfectly in sync with the national average, the institution demonstrates a complete alignment with an environment of maximum scientific security. This very low rate of retractions is a strong positive signal. Retractions can stem from honest errors or systemic failures, but such a minimal score suggests that the university's quality control and supervision mechanisms prior to publication are highly effective, contributing to a national culture of methodological rigor and research integrity.

Rate of Institutional Self-Citation

The institution's Z-score of -0.421 matches the national average, indicating a low and statistically normal level of risk. This suggests that the university's citation practices are consistent with those of its national peers. A certain degree of self-citation is natural as it reflects the progression of established research lines. The low value observed here confirms that the institution is not operating in a scientific 'echo chamber' and that its academic influence is not being artificially inflated by endogamous dynamics, but rather is validated by the broader scientific community.

Rate of Output in Discontinued Journals

The institution shows a Z-score of -0.397, identical to the national figure, which represents a total alignment with a secure research environment. This very low rate indicates that the university's researchers exercise excellent due diligence in selecting publication venues. A high proportion of output in discontinued journals can be a critical alert for engagement with predatory or low-quality media. The university's performance in this area demonstrates a strong commitment to channeling its scientific production through reputable outlets that meet international ethical and quality standards, thus protecting its reputation and resources.

Rate of Hyper-Authored Output

The institution's Z-score of 1.875 is identical to the national average, placing it in a state of standard crisis where it is immersed in a generalized and critical risk dynamic. This significant score is a major red flag. While extensive author lists are legitimate in 'Big Science' fields, a high rate outside these contexts can indicate systemic author list inflation, which dilutes individual accountability and transparency. This shared high-risk level suggests an urgent, system-wide need to differentiate between necessary massive collaboration and the prevalence of 'honorary' or political authorship practices that compromise research integrity.

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

With a Z-score of 1.537, identical to the national average, the institution's performance reflects a systemic pattern of risk shared at the national level. This medium-risk score points to a notable dependency on external partners for achieving high-impact research. A wide positive gap, where overall impact is high but the impact of institution-led research is low, signals a significant sustainability risk. It suggests that the university's scientific prestige may be largely exogenous and dependent on its strategic positioning in collaborations where it does not exercise primary intellectual leadership, prompting a strategic reflection on building greater internal capacity for high-impact innovation.

Rate of Hyperprolific Authors

The institution's Z-score of -0.929 is perfectly aligned with the national average, indicating a shared environment of maximum scientific security in this regard. This very low score is a positive indicator of a healthy research culture. Extreme individual publication volumes can challenge the credibility of meaningful intellectual contribution and may point to risks like coercive authorship or other malpractices. The absence of such signals at both the institutional and national levels suggests a research ecosystem that prioritizes the quality and integrity of the scientific record over the sheer volume of output.

Rate of Output in Institutional Journals

With a Z-score of -0.268, identical to the national average, the institution demonstrates complete synchrony with a national environment that maintains high standards of publication ethics. This very low score indicates that the university is not overly reliant on its own journals for dissemination. Excessive use of in-house journals can create conflicts of interest and academic endogamy by bypassing independent external peer review. The university's strong performance here shows a commitment to global visibility and competitive validation, avoiding the use of internal channels as 'fast tracks' to inflate productivity.

Rate of Redundant Output

The institution's Z-score of -0.456, which matches the national average, points to a statistically normal and low-risk situation. This indicates that the university's publication practices are typical for its context and do not raise concerns about data fragmentation. While citing previous work is essential, massive bibliographic overlap can signal 'salami slicing'—the practice of dividing a study into minimal units to inflate publication counts. The low score suggests that the institution fosters a culture where researchers prioritize the communication of significant new knowledge over artificially maximizing publication volume.
