Where does movement collide?

In sociology a movement is an organized, sustained effort by a group of people acting together to promote or resist a change in society. Lorenz von Stein's 1850 Geschichte der sozialen Bewegung in Frankreich introduced the term social movement into scholarly writing while describing collective political action in France, and McCarthy and Zald's 1977 Resource Mobilization and Social Movements reframed such movements as the product of organizations that gather people, money, and attention. The referent is a coordinated body of people pressing a shared claim over time, counted by participants and organizations, and it has nothing to do with a division of a musical work or the physical travel of an organism.[1][2]

In movement ecology a movement is the change in an organism's spatial position over time, from a single step to a lifetime of dispersal or migration. Nathan and colleagues' 2008 A movement ecology paradigm for unifying organismal movement research proposed a common framework linking why, how, when, and where organisms move, built from the animal's internal state, its movement and navigation abilities, and the surrounding environment. The referent is the physical displacement of a living thing through space, recorded as tracks and distances, and it bears no relation to a campaign by a group of people or a section of a piece of music.[3]
