The aim of this work is to introduce a new method for forecasting major El Niño/ La Niña events with the use of a wavelet-based mode decomposition. These major events are related to sea surface temperature anomalies in the tropical Pacific Ocean: anomalous warmings are known as El Niño events, while excessive coolings are referred as La Niña episodes. These climatological phenomena are of primary importance since they are involved in many teleconnections ; predicting them long before they occur is therefore a crucial concern. First, we perform a wavelet transform (WT) of the monthly sampled El Niño Southern Oscillation 3.4 index (from 1950 to present) and compute the associated scale spectrum, which can be seen as the energy carried in the WT as a function of the scale. It can be observed that the spectrum reaches five peaks, corresponding to time scales of about 7, 20, 31, 43 and 61 months respectively. Therefore, the Niño 3.4 signal can be decomposed into five dominant oscillating components with time-varying amplitudes, these latter being given by the modulus of the WT at the associated pseudo-periods. The reconstruction of the index based on these five components is accurate since more than 93% of the El Niño/ La Niña events of the last 60 years are recovered and no major event is erroneously predicted. Then, the components are smoothly extrapolated using polynomials and added together, giving so several years forecasts of the Niño 3.4 index. In order to increase the reliability of the forecasts, we perform several months hindcasts (i.e. retroactive probing forecasts) which can be validated with the existing data. It turns out that most of the major events can be accurately predicted up to three years in advance, which makes our methodology competitive for such forecasts. Finally, we discuss the El Niño conditions currently undergone and give indications about the next La Niña event. [less ▲]

Il y a environ 20 à 60 millions d’années, l’autruche se retrouvait autour de la Méditerranée à l’Ouest, en Chine à l’Est et en Mongolie au nord. Une polémique anime les milieux scientifiques, surtout les paléontologues : les autruches ont-elles migrés d’Afrique vers l’Eurasie ou l’inverse ? Cependant, se référant aux autres espèces, il est unanimement admis qu’ il y a 1 million d’année seulement que plusieurs grands mammifères terrestres ont migré vers le sud en Afrique, les autruches aussi(voir Carte 1). En chine, on a retrouvé dans des caves occupées il y a 2500 ans avant l’ère actuelle, des coquilles d’œufs d’autruche (Anita Holtzhausen & Marlene Kotzé, 1990) La domestication de l’autruche remonte à la plus haute antiquité, et c’est tout naturellement dans le nord de l’Afrique que se rencontrent les témoignages des plus anciennes relations entre l’homme et l’autruche (Njikam N.I., 1997 ; Bruno Cornette et Lebailly, 1998). L’autruche, bien connu des Egyptiens, figure parmi les pictogrammes de l’écriture hiéroglyphique. [less ▲]

Étant donné la place exceptionnelle dont elle jouit dans l'imaginaire collectif occidental depuis près de 4.000 ans, l'Égypte pharaonique est de nos jours l'objet de nombreuses idées reçues, qui, pour la plupart, remontent à l'Antiquité. L'examen que l'ouvrage propose des principales idées reçues générées par notre société à propos de l'Égypte antique vise à constituer un éveil autant à l'Égyptologie, à l'étude de ce que fut réellement la civilisation pharaonique, qu'à la manière dont celle-ci fut récupérée, exploitée et parfois déformée par notre système culturel, à ce que l'on appelle en Histoire la réception culturelle de l'Égypte.

The notion of ‘basic vocabulary’ is associated with the linguist and anthropologist Morris Swadesh, who proposed a list of 200 (and later 100) items. These lists, while widely used in historical and comparative linguistics, are based on Swadesh’s intuitions rather than on empirical research. More recently, however, the Leipzig Loanword Typology Project conducted a cross-linguistic survey of loanwords (Haspelmath & Tadmor 2009). One of the results is a 100-item list of basic vocabulary entries — the ‘Leipzig-Jakarta list of basic vocabulary.’ This list is the product of four factors, computed for a database of 1440 meanings in 41 languages: borrowability, representation in the database, analyzability / simplicity, and age. As Tadmor (2009) points out, this is the first list of basic vocabulary items based on extensive cross-linguistic comparison, and it constitutes a ‘full-fledged basic vocabulary’ that ‘comprises the notions normally associated with this concept: stability (our age score), universality (our representation score) and simplicity (our analyzability score), as well as resistance to borrowing (our unborrowed score)’ (2009: 68). In this talk, we examine this list of 100 meanings in order to evaluate the influence of Greek on the Coptic basic vocabulary, or — to put it the other way around — the ‘Egyptian¬ness’ of the Coptic lexicon, which seems to reflect an intense language contact situation. As a first step, Coptic data were collected from Crum (1939), the most extensive Coptic dictionary, for four dialects: Sahidic, Bohairic, Fayyumic, and Akhmimic. All Coptic lexemes associated with a meaning on the list were collected, even if poorly attested. Additionally, a questionnaire was been submitted to Copticists in order to detect Greek loanwords that would also be used for expressing these 100 meanings. Furthermore, we used etymological tools (Černý 1976; Westendorf 1977; Vycichl 1983) in order to attribute an age score (from 0 = Greek loanword to 4 = Old Egyptian) to the lexemes at two levels: the formal level (when is the word first attested in Ancient Egyptian) and the semantic level (when is the Coptic meaning first associated with this word). The vast majority of meanings (ca. 85%) have at least one pre-Coptic Egyptian cognate, most of which are already attested in Old Kingdom texts. As a result of this study, we are able (1) to evaluate the influence of Greek on the basic vocabulary of the main Coptic dialects, (2) to describe the basic vocabulary of Coptic dialects independently and to observe how they differ from one another, (3) to produce a first estimate of the rate of change in basic vocabularies over the course of Egyptian as a whole.
