uncertainty proprietary uncertainty Jie Zheng classification to be confirmed Oliver He http://www.nusap.net/modules.php?op=modload&name=NS-Glossary&file=index Jinjing Guo Proprietary uncertainty occurs due to the fact that information and knowledge about an issue are not uniformly shared among all those who could potentially use it. That is, some people or groups have information that others don't and may assert ownership or control over it. "Proprietary uncertainty becomes most salient when it is necessary to reconcile the general needs for safety, health, and environment protection with more sectorial needs pertaining, for instance, to industrial production and process, or to licensing and control procedures" (De Marchi, 1994). De Marchi notes that 'whistle blowing' is another source of proprietary uncertainty in that there is a need for protection of those who act in sharing information for the public good. Proprietary uncertainty would typically be high when knowledge plays a key role in assessment, but is not widely shared among participants. An example of such would be the case of external safety of military nuclear production facilities. 所有权不确定性
