Technological Uncertainty and Standardization Strategies: A Coopetition Framework [PDF]

IEEE Transactions on Engineering Management
Standards may be arrived at through various coordination mechanisms, including cooperation, coopetition, or competition. This article explores how technological uncertainty affects the coordination mechanism for standardization. The article is based on the Community Innovation Survey, a sizeable firm-level survey representative of the Luxembourgish ...

The Uncertainty of Reference Standards--A Guide to Understanding Factors Impacting Uncertainty, Uncertainty Calculations, and Vendor Certifications [PDF]

Journal of Analytical Toxicology, 2009
Certified solution standards are widely used in forensic toxicological, clinical/diagnostic, and environmental testing. Typically, these standards are purchased as ampouled solutions with a certified concentration. Vendors present concentration and uncertainty differently on their Certificates of Analysis.

Normative uncertainty and societal preferences: the problem with evaluative standards

Frontiers in Neuroergonomics, 2023
Many technological systems these days interact with their environment with increasingly little human intervention. This situation comes with higher stakes and consequences that society needs to manage. No longer are we dealing with 404 pages: AI systems today may cause serious harm. To address this, we wish to exert a kind of control over these systems,
