Portland State University

EXECUTIVE SUMMARY AND STRATEGIC VISION

Portland State University presents a robust and well-balanced scientific integrity profile, reflected in an overall risk score of -0.129. The institution demonstrates exceptional strengths in maintaining intellectual leadership, with a minimal gap between its overall research impact and the impact of its self-led output. Further areas of excellence include a very low incidence of hyperprolific authorship and publication in discontinued journals, indicating a culture that prioritizes quality and due diligence. Thematic strengths, as evidenced by SCImago Institutions Rankings data, are concentrated in areas such as Business, Management and Accounting; Social Sciences; and Economics, Econometrics and Finance. However, moderate risk signals in the Rate of Multiple Affiliations and Rate of Retracted Output require strategic attention. These specific vulnerabilities could potentially undermine the institution's mission to deliver "innovative research" with "global impact," as they touch upon the transparency of collaboration and the rigor of pre-publication quality control. To fully align its operational practices with its stated values of excellence and community engagement, it is recommended that the University undertake a targeted review of its authorship affiliation policies and post-publication review processes, thereby reinforcing its already strong foundation of scientific integrity.

ANALYSIS BY INDICATOR

Rate of Multiple Affiliations

The institution's Z-score of 1.066 is notably higher than the national average of -0.514, indicating a greater sensitivity to this risk factor compared to its national peers. This moderate deviation warrants a review of affiliation policies. While multiple affiliations are often a legitimate result of researcher mobility or partnerships, disproportionately high rates can signal strategic attempts to inflate institutional credit or “affiliation shopping.” This practice, if not carefully managed, could dilute the institution's unique contribution and misrepresent its collaborative efforts, potentially impacting the perceived integrity of its research output.

Rate of Retracted Output

With a Z-score of 0.418, the institution shows a higher rate of retracted publications than the national average of -0.126. This suggests a moderate deviation from the national standard and highlights a potential vulnerability. Retractions are complex events, but a rate significantly higher than the average suggests that quality control mechanisms prior to publication may be failing systemically. This indicator alerts to a potential weakness in the institution's integrity culture, indicating possible recurring malpractice or a lack of methodological rigor that requires immediate qualitative verification by management to safeguard its scientific reputation.

Rate of Institutional Self-Citation

The institution demonstrates a prudent profile in its citation practices, with a Z-score of -0.673, which is more rigorous than the national standard of -0.566. This indicates a healthy level of external engagement and validation. A certain level of self-citation is natural and reflects the continuity of established research lines. By maintaining a low rate, the institution successfully avoids signals of scientific isolation or 'echo chambers,' ensuring its academic influence is driven by broad community recognition rather than being inflated by internal dynamics.

Rate of Output in Discontinued Journals

The institution exhibits total operational silence in this area, with a Z-score of -0.473, indicating an absence of risk signals that is even more pronounced than the already low national average of -0.415. This exceptional performance demonstrates strong due diligence in selecting dissemination channels. It confirms that the institution's researchers are effectively avoiding media that do not meet international ethical or quality standards, thereby protecting its resources and reputation from the risks associated with 'predatory' or low-quality publishing practices.

Rate of Hyper-Authored Output

The institution shows significant resilience against national trends, with a Z-score of -0.657 in contrast to the country's medium-risk score of 0.594. This suggests that internal control mechanisms are effectively mitigating systemic risks related to authorship. While extensive author lists can be legitimate in 'Big Science,' a low score outside these contexts is a positive sign. It indicates that the institution is successfully promoting transparency and individual accountability, avoiding practices like author list inflation or 'honorary' authorships that can dilute the value of scientific contributions.

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

The institution demonstrates a strong degree of preventive isolation from national risk dynamics, with a very low Z-score of -0.919 compared to the country's medium-risk average of 0.284. This negative gap indicates that the impact of research led by the institution is robust and does not depend on external partners to achieve visibility. This is a key indicator of sustainability and internal capacity, confirming that the institution's scientific prestige is structural and endogenous, stemming from genuine intellectual leadership rather than strategic positioning in collaborations.

Rate of Hyperprolific Authors

With a Z-score of -1.045, the institution maintains a very low-risk profile that is consistent with, and even stronger than, the national standard of -0.275. This absence of signals related to hyperprolificacy is a positive indicator of a balanced research environment. Extreme individual publication volumes can challenge the limits of meaningful intellectual contribution. The institution's low score suggests a culture that prioritizes the quality and integrity of the scientific record over sheer quantity, effectively avoiding risks such as coercive authorship or the assignment of authorship without real participation.

Rate of Output in Institutional Journals

The institution's Z-score of -0.268 is in near-perfect alignment with the national average of -0.220, demonstrating integrity synchrony with an environment of maximum scientific security. This indicates that the institution is not overly reliant on its own journals for dissemination. This alignment confirms that the institution's scientific production is predominantly validated through independent external peer review, thus avoiding potential conflicts of interest or academic endogamy and ensuring its research competes on a global stage.

Rate of Redundant Output

The institution displays strong institutional resilience, with a low-risk Z-score of -0.458 that stands in stark contrast to the medium-risk national average of 0.027. This suggests that internal policies or academic culture effectively discourage the practice of data fragmentation. The institution's low score indicates that its researchers are focused on publishing significant new knowledge rather than artificially inflating productivity by dividing studies into 'minimal publishable units.' This commitment to substance over volume strengthens the integrity of the scientific evidence it produces.
