Dynamical systems theory and chaos theory deal with the long-term qualitative behavior of dynamical systems.Here, the focus is not on finding precise solutions to the equations defining the dynamical system (which is often hopeless), but rather to answer questions like "Will the system settle down to a steady state in the long term, and if so, what are the possible steady states?", or "Does ...
A shift-share analysis, used in regional science, political economy, and urban studies, determines what portions of regional economic growth or decline can be attributed to national, economic industry, and regional factors.
The size and profit-seeking imperative of dominant media corporations create a bias.The authors point to how in the early nineteenth century, a radical British press had emerged that addressed the concerns of workers, but excessive stamp duties, designed to restrict newspaper ownership to the 'respectable' wealthy, began to change the face of the press.
