What makes Australians happy?

Lately I’ve been exploring demographic and social data, including looking at the Australian data in the World Values Survey. Of particular interest are data on self-reported happiness. Among women, financial stress and poor health contribute to unhappiness, as might be expected. Socially conservative women report being happier, and single women report being less happy. Finally, women who attend religious services once per week or once per month are happier than those who do not attend religious services, or those who attend religious services more than once per week. This is broadly consistent with literature on the effects of religion on mental health.

Among men, financial stress and poor health act in the same way as for women. In terms of marital status, however, it is separated men who are the least happy. Male happiness is also closely tied to employment status, with unemployed (and, to a lesser extent, self-employed) men reporting more unhappiness.


Gender and Health

Lately I’ve been exploring demographic data related to women’s health. Among other things, this involved looking at the Australian data in the World Values Survey, which includes a self-reported measure of health. For women, this depends on a number of other variables, including age:

For men, the age effect is weaker:

Presumably, this is because male health problems are more likely to be fatal, which is why there is an excess of women amongst the elderly, as indicated by Australian census data:


Preferred public female dress in Muslim countries

A recent University of Michigan study of preferred public female dress in Muslim countries has some fascinating findings. Men and women from seven countries were asked to identify the most appropriate female dress, from six options. The mosaic plot above is my visualisation of the results. The images are the ones used in the study, scaled so that areas reflect percentages of responses.

A more detailed breakdown of the results shows that men and women gave similar rankings. In Pakistan, college-educated people tended to be less conservative. In Lebanon, the least conservative option (#6) was associated with Christianity, while in Turkey, it was associated with Shia Islam. Of the seven countries studied, Saudi Arabia was the most conservative.

The Cavendish

The Cavendish Laboratory at Cambridge has had more than its fair share of major scientific discoveries. In this old building (which the Laboratory no longer occupies) worked James Clerk Maxwell, Lord Rayleigh, J. J. Thomson, Ernest Rutherford, Lawrence Bragg, James Watson, and Francis Crick, among others. Their discoveries included the electron, the neutron, and the structure of DNA. I’ve always wondered: did the genius ooze into the walls? Would I become a better scientist if I could sleep a night inside the old Cavendish building? Or would I see ghosts performing experiments?

The Cavendish opened on 16th June 1874, receiving a write-up in the (then new) journal Nature (10: 139–142, 25 June). A description by William Garnett is also available here. The inscription “Magna opera Domini exquisita in omnes voluntates ejus” was placed over the doors. This is taken from Psalm 110:2 in the Clementine Vulgate (Psalm 111:2 in Protestant Bibles). The English version, “The works of the Lord are great, sought out of all them that have pleasure therein,” was placed over the doors of the Laboratory’s new building.

In 1882 the Cavendish accepted women on equal terms with men, although the University itself did not award degrees to women until 1948. Eleanor Sidgwick was the first woman to work at the Cavendish (1880–1882). Elsa Neumann joined in 1899, and Katharine Burr Blodgett in 1924.

Theatres of Glass: a book review


Theatres of Glass by Rebecca Stott (2003)

I recently read Theatres of Glass: The Woman who Brought the Sea to the City by Rebecca Stott. The book tells the story of Anna Thynne, wife of the Reverend Lord John Thynne, who was Sub-Dean of Westminster Abbey from 1831 to 1881.


Anna with her daughters Selina and Emily

Beginning in 1846, when she took her children on a holiday to Devonshire, Anna Thynne developed the marine aquarium (realising that constant aeration of the water was required) and studied stony corals such as Caryophyllia smithii, publishing an article with the deeply religious zoologist Philip Gosse.

Stott quotes Tennyson’s The Princess as an indication of the Victorian mania for collection:

And me that morning Walter showed the house,
Greek, set with busts: from vases in the hall
Flowers of all heavens, and lovelier than their names,
Grew side by side; and on the pavement lay
Carved stones of the Abbey-ruin in the park,
Huge Ammonites, and the first bones of Time;
And on the tables every clime and age
Jumbled together; celts and calumets,
Claymore and snowshoe, toys in lava, fans
Of sandal, amber, ancient rosaries,
Laborious orient ivory sphere in sphere,
The cursed Malayan crease, and battle-clubs
From the isles of palm: and higher on the walls,
Betwixt the monstrous horns of elk and deer,
His own forefathers’ arms and armour hung.

Indeed, as Stott explains, Anna Thynne’s work (together with the book The Aquarium: an unveiling of the wonders of the deep sea by Gosse) helped extend that mania to aquaria as well. My understanding of the chronology is this:

1806: Anna born (April 1)
1824: Anna marries Lord John Thynne (age 17, almost 18)
1841: Ward experiments with freshwater aquaria
1846: Anna begins her marine aquarium (age 40)
1849: Anna moves to Tenby in Pembrokeshire
1850: Anna conducts detailed investigations of the “Madrepores” in her aquarium
1850: Warrington experiments with freshwater aquaria
1852: Anna abandons her aquarium and moves to Hawnes Park, Bedfordshire
1852: Warrington experiments with marine aquaria; the London Zoo establishes an aquarium
1854: Gosse publishes The Aquarium
1856: Second edition of The Aquarium
1859: Anna (age 53) and Gosse publish “On the increase of Madrepores” in The Annals and Magazine of Natural History
1866: Anna dies (age 60)

Overall, a very enjoyable book, about a forgotten heroine of science. I didn’t quite feel I’d gotten inside Anna’s head, but that is probably because the limited range of source material often forces Stott to speculate. Anna’s role is weakened a little by the fact that Gosse was unaware of her when he wrote his book in 1854, although he lists her as one of three pioneers in the second edition (and quotes the sentence “The individual to whom is due the merit of having introduced marine vivaria into London is Mrs. Thynne,” which justifies the carefully chosen subtitle of Stott’s book).

Also, I was perhaps subconsciously expecting some of the flavour of Barchester Towers, in a book about the wife of a Sub-Dean. No doubt that is the wrong way to think about Anna Thynne, but Stott does not give a strong alternative. I can’t help wish that more source material existed. I would have liked some colour plates in the book too.
