Book Description
L'objectif de cette thèse est d'analyser la demande de trafic aérien afin de fournir des modèles de prévisions à moyen terme (cinq ans) du trafic de la France et des principaux aéroports français, modèles pouvant s'interpréter en terme de comportement économique structurel. Le premier chapitre présente la demande et l'offre de transport aérien. Les différentes variables influençant la demande sont définies dans le chapitre 2. Afin d'analyser la demande, nous utilisons des modèles log linéaires dynamiques de type autorégressifs, non stationnaires, admettant une relation de cointégration et conditionnels à un ensemble de variables exogènes (chapitre 3). Les estimations permettent d'identifier les effets des principaux déterminants de la demande de transport (chapitre 4). Le chapitre 5 présente quelques résultats de prévisions ainsi que la pertinence de ces prévisions pour l'année 2002. Pour finir, le chapitre 6 analyse les conséquences des attentats du 11-09-2001 sur le trafic français.

Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention
Author: Clive L. N. RugglesPublisher:
ISBN: 9780954086770
Category : Archaeoastronomy
Languages : en
Pages : 304
Book Description
This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.
Multi-party Elections in Africa
Author: Michael CowenPublisher:
ISBN:
Category : Literary Collections
Languages : en
Pages : 404
Book Description
This volume contains electoral studies of multiparty politics in 14 African countries during the 1990s. Most are about national elections in Anglophone Africa. There are also less well-known examples from Sudan, Ethiopia and Guinea Bissau. The collection also features studies of the local elections in Namibia and of a significant by-election in Malawi. The multiparty period had been put, wherever possible, within the historical context of earlier elections in Africa. Questions addressed include: how did incumbent governing regimes learn to live with multiparty politics? Why have some elections been so closely fought and others have suffered from apathy? Why has there been relatively open political expression and activity when the elections have increased the political and economic manipulation by incumbent governments? Why have the elections of the 1990s been so marked by local and ethnic variations? To what extent did this wave of democracy result from pressure from donor countries?
