Nationally, a large majority of students still attend government schools, but the expansion of private institutions has created parallel educational systems — systems that are now colliding.
"Countries like Germany, where they are implementing new systems, systems that are meant to improve air traffic control, are having tremendous delays," Mr. Dick said.
If there eventually is a true, integrated social science, it will still be a science of complex, nonlinear systems – systems that are chaotic in the technical sense, and hence not susceptible to detailed long-run forecasts.
When troubleshooting complex systems—systems that encompass not just science and technology but also people and relationships there may be many culprits.
This, by the way, opens the question of the role of technology in shaping transport systems, systems that rely also on societal attitudes, behaviours and beliefs.
To manage this new complexity, we propose an approach based on self-managing systems: systems that can maintain useful functionality despite changes in their environment.
Edits were made to reflect installations of new water systems, systems that had stopped fluoridation, and changes in population.
Two systematic reviews found that active computerised decision support systems (systems that automatically provide individual professionals with advice) are more effective than passive systems, which require professionals to request advice.
She has also studied certain dynamical systems (meaning systems that evolve with time) on moduli space, proving in particular that the system known as the "earthquake flow", whichwas introduced by William Thurston (a 1982 Fields Medalist), is chaotic.
The Saudis do not have a bank supervisory system or auditing systems that would provide a base of information, Mr. Wechsler said.
