It can be used when referring to a particular guideline or path within a broader context, such as a project, discussion, or field of study.
Example: "The team is focusing on a specific direction in their research to ensure they meet the project goals effectively."
Alternatives: "a particular path in" or "a defined course in".
Daniel Kreiss calls it "computational management" -- using technology, specifically webapps, to organize and drive volunteer energy in a specific direction in a sophisticated way.
These act as the brain's internal compass, each of them firing when the animal is facing a specific direction in the horizontal plane, or azimuth.
That's probably because our choices are particularly constrained on the road - in general, all we do is aim to go in a specific direction, in single file, at the speed of our choosing.
For example, traffic flow exhibits a specific direction in space and time.
Note that we confirmed that cell movement was not biased toward a specific direction in all conditions studied (see Figure S1).
Hull et al. (2002) demonstrated that the arrows between the metabolites in glycolysis were interpreted as a stream with a specific direction in the cytosolic solution rather than as a schematic representation of the order of reactions.
Speed, or more to the point, velocity (speed in a specific direction) matters in technology.
Unlike other cytoskeletal motors that produce torque in a specific direction, dynein generates torque in either direction, resulting in bidirectional helical motility.
Latency to enter the periphery (indicative of anxiety) and central zone, angular velocity, which is the animals' ability to turn in a specific direction, general mobility, and time spent in left or right part of the box were measured.
It is easy to derive them by substituting a specific direction for "oriented-direction" in these two definitions, so we omit them here.
