The mutations of the Liberal-Liberal-Democrat Party to (re)conquer power.

2019

This research work is devoted to the study of the Liberal/Liberal-Democrat Party and the organizational changes that its successive leaders implemented between 1976 and 2015 to (re)conquer power. David Steel, Paddy Ashdown, Charles Kennedy and Nick Clegg somehow reclaimed the legacy of Jo Grimond, who had devised the strategy of the realignment of the left in the 1950s to manage its relationships with the Conservative and Labour Parties and become a government party.Each of them gave their own version of this strategy to adapt to a changing environment with a party system that was no longer a solid two-party system. The successive organizational mutations (professionalization, a change in t…

Reproduction behaviors : permanencies and changes : for a contextual and dynamic approach of the fertility

2015

Current levels of African fertility are, for most observers, the expression of a continuation of traditional values of ancestral essence. For those observers, the traditional values continue to determine reproductive behavior, despite the economic, political and social changes. Based on the case of the Republic of Congo, dynamic and contextual analysis of these behaviors, reveal that these are rather clear break from the current level of fertility; they suggest significant unmet need for birth control. It is possible that a Malthusian reflex develops gradually, which does not exclude the need for children, contrary to some theories. These behaviors are characterized by profound changes resu…

Détection automatique de chutes de personnes basée sur des descripteurs spatio-temporels : définition de la méthode, évaluation des performances et i…

2013

We propose a supervised approach to detect falls in home environment adapted to location andpoint of view changes. First, we maid publicly available a realistic dataset, acquired in four differentlocations, containing a large number of manual annotation suitable for methods comparison. We alsodefined a new metric, adapted to real-time tasks, allowing to evaluate fall detection performance ina continuous video stream. Then, we build the initial spatio-temporal descriptor named STHF usingseveral combinations of transformations of geometrical features and an automatically optimised setof spatio-temporal descriptors thanks to an automatic feature selection step. We propose a realisticand pragma…

Variabilité de la température entre 1951 et 2014 en Allemagne associée à l’évolution de la floraison des pommiers.

2018

Apple tree bloom onset in Germany has advanced by 2 days/decade in 1951-2014 and by 3 days/decade in 1988-2014, behaving similarly in respect to its evolution since 1951 and its sensitivity to temperature to other species’ phenological spring phases. The evolution however was not linear; by conducting a split moving-window dissimilarity analysis (SMWDA) we were able to detect the “break-period” 1987-1989 which coincides with a breakpoint that has been identified in the phases of the North Atlantic Oscillation (NAO). We observed distinct spatial patterns with apple bloom advancing from southwest to northeast and, most interestingly, a longitudinal gradient in the trend of apple bloom onset r…

Evaluation des simulations spatiales

2006

The general topic is the evaluation of prospective scenarios for urban planning, especially for the management of urban built up areas. Several models of land-use and land-cover change (LUCC), based on different assumptions, allow producing realistic simulations of urban growth. Three ways can be distinguished for measuring the quality of modelings: 1. The choice of a model and its calibration; 2. The validation (showing if results are realistic); 3. The evaluation (showing if results respect defined planning goals). Measurement methods must be associated to these three steps.

Évolution des structures spatiales récurrentes des températures quotidiennes en Bourgogne.

2011

6 pages; International audience; L’objectif est de définir, à partir de 24 stations météorologiques, différentes structures spatiales récurrentes de larépartition des températures minimales (Tn) et maximales (Tx) en Bourgogne. Après avoir désaisonnalisé les séries detempératures, une Classification Hiérarchique Ascendante (CHA) est utilisée pour regrouper les jours ayant des structuresspatiales similaires. Huit classes ont été définies, quatre pour les Tn et quatre pour les Tx. Pour les deux variables, ellesidentifient les cas de gradient thermique (i) Nord-Ouest/Sud-Est, (ii) Sud-Est/Nord-Ouest, (iii) altitudinal positif et (iv)altitudinal négatif. Les fréquences d’occurrences de ces struc…
