Marcan priority is the hypothesis that the Gospel of Mark was the first of the three synoptic gospels to be written, and was used as a source by the other two (Matthew and Luke). It is a central element in discussion of the synoptic problem; the question of the documentary relationship among these three gospels.

Priority traffic signs indicate the order in which vehicles should pass intersection points. Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes.

In patent, industrial design rights and trademark laws, a priority right or right of priority is a time-limited right, triggered by the first filing of an application for a patent, an industrial design or a trademark respectively. The priority right allows the claimant to file a subsequent application in another country for the same invention, design, or trademark effective as of the date of filing the first application.

<parallel> A technique for avoiding priority inversion by temporarily raising the prioriry of all processes that want to access a shared resource to the highest priority level of any of them. Priority inversion occurs where a low priority process, L is holding a resource required by a high priority process, H, but L is not running because a medium priority process, M is running. Under priority inheritance, L temporarily inherits H's priority, allowing L to run and release the resource H is waiting for. For example, an ambulance (H) is stuck behind a lorry (L) waiting at a junction (the shared resource) for a gap in a line of cars (M) using the junction. Applying priority inheritance, the cars give way to the lorry as they would to the ambulance, thus allowing the lorry and then the ambulance to use the junction. (2005-02-11)

In real-time computing, priority inheritance is a method for eliminating unbounded priority inversion. Using this programming method, a process scheduling algorithm increases the priority of a process (A) to the maximum priority of any other process waiting for any resource on which A has a resource lock (if it is higher than the original priority of A).

Jacob Two-Two is a series of children's books written by Canadian author Mordecai Richler: Jacob Two-Two Meets the Hooded Fang (1975), Jacob Two-Two and the Dinosaur (1987) and Jacob Two-Two's First Spy Case (1995) written by Mordecai Richler, and Jacob Two-Two on the High Seas (2009) written by Cary Fagan.

The Medical Priority Dispatch System (MPDS), sometimes referred to as the Advanced Medical Priority Dispatch System (AMPDS) is a unified system used to dispatch appropriate aid to medical emergencies including systematized caller interrogation and pre-arrival instructions. Priority Dispatch Corporation is licensed to design and publish MPDS and its various products, with research supported by the International Academy of Emergency Medical Dispatch (IAEMD).

The Dual Sector model, or the Lewis model, is a model in Developmental economics that explains the growth of a developing economy in terms of a labour transition between two sectors, a traditional agricultural sector and a modern industrial sector.

Two-fluid model is a macroscopic traffic flow model to represent traffic in a town/city or metropolitan area, put forward in the 1970s by Ilya Prigogine and Robert Herman.
