Pandi (littéralement : « en espérant un fils »), Laidi (« un garçon va suivre »), ou Yehao (« ça va aussi »), c’est ainsi que sont nommées, dans les campagnes chinoises, les fillettes qui ont eu la malchance de naître en lieu et place du fils tant attendu… Car en Chine, en dépit de la modernisation économique des dernières décennies, une fille reste investie d’une bien moindre valeur qu’un fils. Dans les représentations sociales, un garçon présente divers atouts inhérents à son sexe, dont les filles sont globalement dépourvues. Victimes de leur statut dévalorisé, les filles naissent moins nombreuses qu’elles ne le devraient et meurent dans des proportions anormalement élevées. Ainsi, contrairement aux évolutions démographiques observées dans le reste du monde s’ensuit une masculinisation de la population chinoise, sa part masculine augmentant plus vite que sa part féminine. D’un point de vue strictement démographique, la situation des Chinoises est donc, relativement à celle des hommes, l’une des plus mauvaises qui soient. Là est l’immense paradoxe de cette société en marche vers la |

modernisation. Alors que les Chinoises se sont largement émancipées depuis les années 1950, de graves atteintes sont maintenant portées à leur existence. La législation chinoise, pourtant explicite sur la question de la protection des droits et des intérêts des femmes, ne permet pas de garantir leur droit le plus élémentaire : celui de vivre. |

Sommario/riassunto |
|
The focus of this book is the large-scale statistical behavior of solutions of divergence-form elliptic equations with random coefficients, which is closely related to the long-time asymptotics of reversible diffusions in random media and other basic models of statistical physics. Of particular interest is the quantification of the rate at which solutions converge to those of the limiting, homogenized equation in the regime of large scale separation, and the description of their fluctuations around this limit. This self-contained presentation gives a complete account of the essential ideas and fundamental results of this new theory of quantitative stochastic homogenization, including the latest research on the topic, and is supplemented with many new results. The book serves as an introduction to the subject for advanced graduate students and researchers working in partial differential equations, statistical physics, probability and related fields, as well as a comprehensive reference for experts in homogenization. Being the first text concerned primarily with stochastic (as opposed to periodic) homogenization and which focuses on quantitative results, its perspective and approach are entirely different from other books in the literature. . |
