Forecasting inflation using economic indicators: the case of France

In order to provide short‐run forecasts of headline and core HICP inflation for France, we assess the forecasting performance of a large set of economic indicators, individually and jointly, as well as using dynamic factor models. We run out‐of‐sample forecasts implementing the Stock and Watson (1999) methodology. We find that, according to usual statistical criteria, the combination of several indicators—in particular those derived from surveys—provides better results than factor models, even after pre‐selection of the variables included in the panel. However, factors included in VAR models exhibit more stable forecasting performance over time. Results for the HICP excluding unprocessed food and energy are very encouraging. Moreover, we show that the aggregation of forecasts on subcomponents exhibits the best performance for projecting total inflation and that it is robust to data snooping.

Integral equations between theory and practice: the cases of Italy and France to 1920

In 1899, Ivar Fredholm discovered how to treat an integral equation using conceptual methods from linear algebra and use these ideas to solve certain classes of boundary value problems. He formulated a theory allowing him both to unify large classes of problems and to attack several problems fruitfully. The historical literature on the theory of integral equations has concentrated largely on the unification that was afforded by Hilbert and his school, but has not throughly investigated the roots of the subject in the older theory of partial differential equations, as developed for instance by Fredholm himself but also by Volterra and Levi-Civita. By concentrating on work issuing from this older tradition, in particular on French and Italian work, the paper shows how the new theory of integral equations was enthusiastically received, especially for its fruitful applications to areas of mathematical physics such as hydrodynamics, elasticity, and heat theory.

The stage-dependent resistance of the chorion to external chemical damage and its relationship to embryonic diapause in the annual fish, Nothobranchius guentheri

The resistance of the embryonic chorion of the annual fish Nothobranchius guentheri to chemical damage in vivo was investigated by the exposure of the embryos to protease. Embryos at stages 20, 33, and 43 were the most resistant to enzymatic action. These stages of development correspond respectively to the stages at which diapause I, diapause II, and 'delayed hatching' may occur. The magnitude of the resistance was further enhanced when diapause was induced prior to the treatment.

遥感技术在全国第一次河流湖泊普查中的应用

河流湖泊是水体环境的主要形式,是生活用水、生产用水、生态用水的重要来源,对社会经济的发展起着至关重要的作用.遥感技术为全国第一次河湖普查提供了重要的技术支撑,本次河流湖泊普查涉及到的遥感影像数据为中巴地球资源卫星(CBERS)数据及2.5m高空间分辨率影像.为全面查清我国湖泊数量、分布等基本情况,本文对全国第一次河湖清查阶段中利用CBERS数据进行湖泊对象清查进行了介绍;并着重讨论了ENVI\IDL环境下CBERS数据批处理模式的建立及应用,为同类CBERS数据的大范围、大批量数据应用提供一定的参考和依据;同时,全国1:5万分幅2.5m高空间分辨率影像作为重要的河流水系现势性检查数据,本文对利用此数据进行1:5万DLG数字水系的合理性检查进行了探讨,并利用ENVI\IDL实现了全国水系的自动化检查;作为水系复核工作中的有效工具,增强了河流水系提取的现势性,提高了河流水系的精度,实现了水系提取数据精度源于并高于1:5万DLG数字水系的目的.
