Naval Postgraduate School

EXECUTIVE SUMMARY AND STRATEGIC VISION

The Naval Postgraduate School demonstrates a robust and well-managed scientific integrity profile, reflected in an overall risk score of -0.058. The institution exhibits significant strengths in areas of operational integrity, with very low risk signals in the Rate of Multiple Affiliations, Output in Discontinued Journals, Hyperprolific Authorship, and Output in Institutional Journals. These results indicate strong governance and adherence to best practices. However, this solid foundation is contrasted by areas requiring strategic attention, particularly a significant risk in the Rate of Redundant Output (Salami Slicing) and medium-level risks in Retracted Output and Institutional Self-Citation. Thematically, the institution's research strengths are most prominent in Engineering, Physics and Astronomy, and Arts and Humanities, according to SCImago Institutions Rankings data. While these rankings affirm its capacity for high-level research, the identified integrity risks, especially the practice of fragmenting studies, directly challenge the core mission of fostering "academic excellence" and "meritorious research." To fully align its operational reality with its strategic vision, the institution is encouraged to implement targeted review mechanisms and training programs aimed at mitigating these specific vulnerabilities, thereby ensuring its intellectual capital is built upon a foundation of unimpeachable integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution presents a Z-score of -1.194, which is notably lower than the national average of -0.514. This result indicates a state of low-profile consistency, where the complete absence of risk signals surpasses the already low standard observed nationally. This demonstrates that the institution's affiliation practices are exceptionally clear and well-defined. While multiple affiliations can be a legitimate outcome of collaboration, the institution's very low rate confirms it is not exposed to risks associated with strategic attempts to inflate institutional credit or "affiliation shopping," reflecting a highly transparent and focused research environment.

Rate of Retracted Output

With a Z-score of 0.652, the institution shows a moderate deviation from the national average of -0.126. This suggests a greater sensitivity to risk factors than its peers, warranting a closer look at its quality control mechanisms. Retractions are complex; while some signify responsible error correction, a rate significantly higher than the national baseline alerts to a potential vulnerability in the institution's integrity culture. This Z-score suggests that pre-publication quality controls may be failing more frequently than expected, pointing to possible recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management.

Rate of Institutional Self-Citation

The institution's Z-score of 0.650 represents a moderate deviation from the national average of -0.566. This indicates that the center is more sensitive to this risk factor than its national counterparts. A certain level of self-citation is natural, reflecting ongoing research lines. However, this disproportionately high rate signals a potential for concerning scientific isolation or an "echo chamber" where work is validated without sufficient external scrutiny. This value warns of the risk of endogamous impact inflation, suggesting that the institution's academic influence may be oversized by internal dynamics rather than by recognition from the global scientific community.

Rate of Output in Discontinued Journals

The institution's Z-score of -0.489 is slightly below the national average of -0.415, indicating a state of total operational silence in this area. This performance demonstrates an absence of risk signals that is even stronger than the already very low national benchmark. This result points to excellent due diligence in selecting dissemination channels for its research. It confirms that the institution is effectively avoiding channeling its scientific production through media that fail to meet international ethical or quality standards, thereby protecting itself from the severe reputational risks associated with "predatory" or low-quality practices.

Rate of Hyper-Authored Output

With a Z-score of -0.752, the institution shows a low-risk profile that contrasts sharply with the medium-risk national average of 0.594. This demonstrates institutional resilience, as internal control mechanisms appear to be successfully mitigating systemic risks prevalent in the country. This low rate suggests that the institution effectively distinguishes between necessary large-scale collaboration and practices of author list inflation. By maintaining this control, it upholds individual accountability and transparency, acting as a firewall against the national trend toward honorary or political authorship practices.

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

The institution's Z-score of 0.079 is considerably lower than the national average of 0.284, although both fall within the medium-risk category. This reflects a differentiated management approach, where the institution successfully moderates a risk that appears more common across the country. A wide positive gap can signal a sustainability risk where prestige is dependent on external partners. The institution's smaller gap suggests its scientific prestige is more structurally sound and less reliant on collaborations where it does not exercise intellectual leadership, indicating a healthier balance between internal capacity and partnership-driven impact compared to its national peers.

Rate of Hyperprolific Authors

The institution exhibits a Z-score of -1.413, a figure significantly lower than the national average of -0.275. This demonstrates low-profile consistency, as the near-total absence of risk signals aligns with and even improves upon the low-risk national standard. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution. The institution's exceptionally low score in this area is a strong positive indicator, suggesting a culture that prioritizes the quality and integrity of the scientific record over raw productivity metrics, effectively avoiding risks such as coercive authorship or authorship assigned without real participation.

Rate of Output in Institutional Journals

With a Z-score of -0.268, the institution's performance is nearly identical to the national average of -0.220. This reflects a state of integrity synchrony and total alignment with an environment of maximum scientific security. While in-house journals can be valuable, excessive dependence on them raises conflict-of-interest concerns. The institution's very low rate confirms that it is not at risk of academic endogamy and ensures its scientific production consistently undergoes independent external peer review, thereby maximizing its global visibility and avoiding the use of internal channels as "fast tracks" for publication.

Rate of Redundant Output

The institution's Z-score of 2.666 is a significant-risk outlier, indicating a sharp accentuation of a vulnerability that is only moderately present in the national system (Z-score: 0.027). This high value serves as a critical alert for the practice of data fragmentation or "salami slicing," where a coherent study is divided into minimal publishable units to artificially inflate productivity. This practice distorts the available scientific evidence and overburdens the peer-review system. The severity of this indicator suggests an urgent need to review publication policies and author guidelines to ensure that the focus shifts from volume to the generation of significant new knowledge.
