Rethinking Revolutions from 1905 to 1934

Letters 1934..1934

Sir, With interest we read the editorial by Wolf on obesity as a renal risk factor [1]. We fully support the author’s view that overweight and insulin resistance, as mediators of renal risk, deserve attention not only in morbidly obese patients with overt insulin resistance, but also in renal patients with less severe obesity. Recent data from our group suggest that the impact of overweight and...

Site response of the Ganges basin inferred from re-evaluated macroseismic observations from the 1897 Shillong, 1905 Kangra, and 1934 Nepal earthquakes

We analyze previously published geodetic data and intensity values for the Ms = 8.1 Shillong (1897), Ms = 7.8 Kangra (1905), and Ms = 8.2 Nepal/Bihar (1934) earthquakes to investigate the rupture zones of these earthquakes as well as the amplification of ground motions throughout the Punjab, Ganges and Brahmaputra valleys. For each earthquake we subtract the observed MSK intensities from a synt...

Technological Revolutions

In skill-biased (de-skilling) technological revolutions learning investments required by new machines are greater (smaller) than those required by preexisting machines. Skill-biased (de-skilling) revolutions trigger reallocations of capital from slow(fast-) to fast(slow-) learning workers, thereby reducing the relative and absolute wages of the former. The model of skill-biased (de-skilling) re...

Philosophical Revolutions

Analytical approach to model of scientific revolutions

The model of scientific paradigms spreading throughout the community of agents with memory is analyzed using the master equation. The case of two competing ideas is considered for various networks of interactions, including agents placed at Erd˝ os-Rényi graphs or complete graphs. The pace of adopting a new idea by a community is analyzed, along with the distribution of periods after which a ne...
