The freesheet Metro reports on a demographic shift. People born in 1948 no longer constitute the largest group in the country. Oh no.

Moreover, more people now leave Finland than arrive, according to figures passed to YLE.

If I understand a report in today’s Guardian correctly (and if Benjamin Haas, the Guardian reporter, has outlined the issue correctly) South Korean law does not take geography as its basis, but rather citizenship.

Every other legal jurisdiction that I have heard of bases itself on geography. This difference has immense implications for what we think about the relationship between citizens, the state, and the legal framework that adjudicates between them.

The idea of representing ideas or thoughts diagrammatically is not a recent one. As early as the third century, Porphyry of Tyros produced map-like images to demonstrate the structure and workings of Aristotle’s philosophical concepts.

However the current usages of the terms “mind mapping” and “concept mapping” are relatively recent. Both terms have known inventors, who have spent many years developing their ideas, and both terms arise from theoretical assumptions or research. Despite the apparent similarity of the terms, and despite the fact that both describe methods of representing ideas diagrammatically, they have completely different aims, and work in very different ways.
