Reply to Stein and Susser

Commentary: peptic ulcer, Susser and Stein and the cohort phenomenon.

Forty years have elapsed since Susser and Stein used mortality data to examine trends in the impact of peptic ulcer disease. 1 They pointed to evidence that morbidity and mortality attributable to peptic ulcer had increased in frequency from the latter part of the 19th century, with gastric ulcer being the first to rise, and that there was evidence from various sources to suggest an abatement m...

Zena Stein, Mervyn Susser and epidemiology: observation, causation and action.

highlight the contributions of two pioneering self-taught epidemiologists, Zena Stein and Mervyn Susser. Their joint paper ‘Civilization and Peptic Ulcer‘, originally published in the Lancet in 1962, appears as one of our series of reprints of important epidemiological papers, along with several commentaries. These include a reflection, 40 years on, by the original authors. A companion series o...

Two lives, three legs, one journey: a retrospective appreciation of Zena Stein and Mervyn Susser.

‘The proponents of a genetic cause of the unequal distribution of intelligence in the social classes have long argued their case with the proponents of the environmental cause ... But whatever effects innate intelligence may have on the social mobility of individuals, current theories in genetics cannot by themselves account satisfactorily for the observed class distribution of low intelligence.’

Holomorphic fiber bundle with Stein base and Stein fibers

A surjective holomorphic map Π : X → Y between complex spaces is said to be a Stein morphism, if for every point y ∈ Y , there exists an open neighborhood U of y such that Π(U) is Stein. In 1977, Skoda [12] showed that a locally trivial analytic fiber bundle Π : X → Ω with Stein base and Stein fibers is not necessarily a Stein manifold. Thus giving a negative answer to a conjecture proposed in ...
