Further, the international community offers development aid to weak states, which helps maintain the facade of a functioning modern state by giving the appearance that the state is capable of fulfilling its implied responsibilities of control and order.

While many of these systems involve cars permanently attached to the cable, the system developed by Poma-Otis, a company formed by the merger of the cable car interests of the Pomagalski ski lift company and the Otis Elevator Company, allows the car to be decoupled from the cable under computer control, and can thus be considered a modern interpretation of the cable car.

The use of D. purpurea extract containing cardiac glycosides for the treatment of heart conditions was first described in the English-speaking medical literature by William Withering, in 1785, which is considered the beginning of modern therapeutics. It is used to increase cardiac contractility ( it is a positive inotrope ) and as an antiarrhythmic agent to control the heart rate, particularly in the irregular ( and often fast ) atrial fibrillation.
