A world of R&D: what changed since the 80s?

Read time: 2 mins

In three decades the world can change of a lot. And it did: Cold War ended and several others started; new nations were born while globalisation kicked in. Yet one thing didn't seem to stop: growth of research. In the history of mankind there has never been as much scientific research as there is now, with millions of scientists and several thousands of institutions working every day. But if growth of science never stopped, it sure changed how science is done and – as important – how it is funded. OECD, in its “Science and Technology Indicators”, gathered data that goes back to 1981; they allow us to see, country by country, how much governments and industry invested in science. We present them in an interactive map.

 

 

Historically most countries have been pretty clear about science: either they like it or they don't very much. Expenditures in research rarely changed dramatically. One notable exception is South Korea, that from 2003 started to invest massively in this field. Today 4% of its GDP is directed towards scientific resarch: only Israel – a much smaller nation – devolves so many of its resources to science. Germany experience the opposite phenomenon: funds growth slowed from 1988. Yet today they are their peak, at 2,88% of GDP.

 

 

At the same time not all investments are created equal. There are countries like Argentina in which most of the funding comes from governmental sources and others where it's industry that pushes for science. Since 1981 the latter has become more common: industry-funded research grew generally at a much faster pace pretty in several countries. That is not the case for Italy and Spain, in which there is not much difference, in quantity, between the two funding sources.

Proteste e salute mentale: il caso di Hong Kong

Secondo un'indagine pubblicata su The Lancet, l’11,2% degli adulti di Hong Kong soffre di sintomi depressivi e il 31,6% manifesta i sintomi del disturbo da stress post-traumatico. L’analisi prende in esame il decennio 2009-19, evidenziando la diversa prevalenza di sintomi depressivi e di PTSD in periodo di pace e durante due ondate di proteste (2014 e 2019) e combinando i risultati con i dati sull’età, l’istruzione e il livello socio-economico del campione.

Un’indagine sulla salute mentale della popolazione di Hong Kong nel decennio 2009-2019, pubblicata su The Lancet, ha analizzato la salute mentale dei cittadini e i fattori di rischio associati allo sviluppo di sintomi depressivi e di disturbo da stress post-traumatico (PTSD). Il quadro che emerge è che a oggi, nell’isola cinese, l’11,2% degli adulti soffre di sintomi depressivi e il 31,6% manifesta i sintomi del disturbo da stress post-traumatico.
