Summary Information Access & Knowledge Equity Undermines
The URL is inaccessible due to HTTP 403 Forbidden error and subscription paywall restrictions. No editorial content can be assessed, but structural access barriers demonstrably undermine Articles 19, 26, and 27 by restricting public access to scientific information and limiting participation in the benefits of research. The paywall model creates de facto discrimination based on economic status and prevents equitable information dissemination.
