But a new report says females are catching up

MARCH 8th was International Women’s Day. That seemed to Elsevier, an academic publisher, a good occasion to publish a report looking at the numbers and performance of female scientists around the world. The report, “Gender in the Global Research Landscape”, analysed the authorship of more than 62m peer-reviewed papers published in 27 subject areas over the past 20 years, in 11 mostly rich countries and in the European Union as a whole. The papers and their citations are indexed in Scopus, a database that is run by Elsevier.

In the EU, and in eight of the 11 countries considered, the share of women authors grew from about 30% in the late 1990s to about 40% two decades later. Brazil and Portugal are closest to equality, each just a percentage point shy of it. In Japan, by contrast, barely a fifth of researchers are female—a fact that may reflect the particularly uncool image science has among Japanese schoolgirls.

Women are best represented in subjects related to health care. In nursing and psychology, for example, they outnumber men in several countries, including America and Britain. Less than a quarter of researchers who publish papers in the physical sciences are women. Perhaps as a consequence of this, inventors who register patents are still almost all men. In the places covered by the report the share of patent applications by women ranges from 8% of those filed in Japan to 26% in Portugal. Women are, however, making progress, even in the still-male-heavy world of engineering. Though they constitute only between 10% and 32% of authors of papers in that field in the places the report looks at, the share of those papers in which a woman is the lead author is between 35% and 52%.

All of this is qualified good news. Women do, nevertheless, still suffer from a “leaky pipeline” phenomenon that sees them drop out of scientific careers at a higher rate than men do. At Imperial College, London, regarded by many as Britain’s leading technological university, about 35% of undergraduates are women. But that percentage falls with each step up the career ladder. At the moment, only 15% of Imperial’s professors are women.

Partly, this stems from the fact that when those professors were undergraduates the sex ratio was even worse. But it also reflects the problem of career-building which women face in all areas, not just science. Even in the most progressive countries, they still shoulder the lion’s share of child care and housework. Boosting their numbers in the laboratory will take more than merely convincing girls that science is cool.

The minimum age of criminal responsibility continues to divide opinion | The Economist

Read The minimum age of criminal responsibility continues to divide opinion by The Data Team (The Economist)

A proposal to let Philippine criminal courts try nine-year-olds has drawn sharp criticism. But in 35 American states, children of any age can be convicted and sentenced

COMMON law has long held that committing a crime requires both a prohibited act and a “mens rea”, or “guilty mind”—the criminal knowing that the act was wrong. There is no global consensus regarding the youngest age at which a child can be deemed to have such intent, and thus can be tried and convicted of a criminal offence. Ten years ago the United Nations Committee on the Rights of the Child recommended an “absolute minimum” age of 12 for criminal responsibility, and urged countries “to continue to increase it to a higher age level”. The Philippines appears poised to move in the opposite direction: lawmakers there have proposed reducing the cut-off from 15 years old to nine. The bill has prompted sharp criticism both at home and abroad, and legislators are still arguing over its text.

Not long ago the Philippines earned a reputation for a relatively progressive stance on this issue. It introduced its current minimum age of criminal responsibility (MACR) in 2006, making it one of just 19 countries whose MACR is 15 or older. However, Rodrigo Duterte, the president, has adopted a harsh “tough-on-crime” agenda. The bill’s supporters say it would stop adult criminals from recruiting children under the age of criminal responsibility for drug-trafficking. Human-rights advocates counter that there is no evidence that this would reduce crime. Instead, says Leo Ratledge of Child Rights International Network, a British charity, it would punish victims of exploitation rather than those who exploit them.

The other members of the MACR-above-14 club are an incongruous bunch. Predictably, they include places like Norway and Sweden, which take a generally liberal approach to criminal justice. However, the top of the table is occupied by less developed countries that happen to have revised their juvenile-justice laws in recent years: in Timor-Leste and Mozambique, the MACR is now 16. Although most European states sit comfortably above the UN recommendation, there are notable exceptions. Scotland can hand out criminal records to eight-year-olds, though legislation is being mooted that will raise the minimum age limit to 12. In the rest of Britain, ten-year-olds can be tried for a crime. This British colonial legacy is reflected in the relatively low MACRs seen in South Africa, Australia and New Zealand. Similarly, Nigeria, India, Pakistan and Bangladesh are among the 21 countries that set a MACR of seven, the lowest national age globally.

In some cases the law is not clear-cut. The MACR in Comoros is based on puberty. It can differ by sex (as in Iran) or type of offence (Malaysia), while Poland and France entrust the issue to judges’ discretion. Nonetheless, even a vague minimum of “puberty” provides more protection than simply having no MACR at all. Just a handful of countries have no national MACR. The most striking is the United States. Although America sets a threshold of 11 years old for federal offences, the overwhelming share of crimes are policed at the state level. And 35 out of the 50 states have not set a MACR, putting them in a club with Cuba, Malaysia (exclusively for terrorism) and Sudan (for drug offences).

Study debunks old concept of how anesthesia works | Phys.Org

Read Study debunks old concept of how anesthesia works (phys.org)

Anesthesia induces unconsciousness by changing the function of proteins that reside on the surface of a thin membrane that forms a barrier around all cells, according to new research from Weill Cornell Medicine scientists. The findings challenge a century-old concept of how anesthetics work and may help guide the development of new agents associated with fewer side effects.

Georg Cantor showed that some infinities are bigger than others. Did he assault mathematical wisdom or corroborate it?

Lofty goals here, but I’m not quite sure he’s really make the case he set out to in these few words. The comments on the article are somewhat interesting, but seem to devolve into the usual pablum seen on such posts. Nothing stuck out to me as a comment by a solid mathematician, which might have been interesting.
