The transformation over time of level sets—the sets of states for which a given function takes a given value—has no reason to be regular, especially in social science, where the structure of these level sets of a given variable may be altered by a fluctuating demography or disrupted by unexpected events, and where the actors contribute to shaping their space through investment policies. The pioneering construction of graphic derivatives of set-valued maps renews the understanding of dynamic level sets in social science. The exemplary case of schooling in 19th-century France shows the set derivatives of level sets and illustrates how the Franco-Prussian War of 1870–1871 disturbed the directions taken in 1867. A comparison of the observed changes of level sets with those observed under rational theoretical policies leads to the conclusion that the actors behaved with the ambition of optimizing the overall schooling incidence while reducing the gap between boys and girls. 相似文献

Here we report a novel amide bond formation strategy from simple thioacid and amine starting materials. The reaction is mediated by unstable but very reactive S-nitrosothioacid intermediates. This fast reaction under mild conditions should be useful in synthesis. 相似文献

An effective "one-pot" synthesis of disubstituted thiophene derivatives employing 3-bromo-2-silyl thiophenes has been developed. A solvent-controlled [1,4] Csp2-->O silyl migration was involved as the key step in this process. 相似文献

Protein S-nitrosation is an important post-translational modification. However, the detection of S-nitrosation is still problematic because S-nitrosation products, that is, S-nitrosothiols, are unstable species. Here a new reaction which can selectively convert unstable S-nitrosothiols to stable thioethers in one-pot under very mild conditions is reported. This reaction has the potential to be applied in the detection of protein S-nitrosation. 相似文献
