Distinguishing the analysis of spatial data from classical analysis is only meaningful if the spatial components bring information. Therefore, testing if the spatial autocorrelation is significant may confirm or deny the need to consider spatial analysis over the classical one. Spatial autocorrelation expresses the dependence between values at neighbouring locations. Several measures of spatial autocorrelation are defined in the literature. Moran’s index, Geary’s ratio and Getis-Ord statistic are the most used statistics. Tests based on these measures have been developed in the literature using asymptotic and permutation results. They are used in practice in many fields, for instance in geography, economics, biogeosciences, medicine, ... However, these tests should be cautiously applied because they are not robust. A single contaminated observation can significantly modify their results. The talk has two main objectives. Firstly, the already available tools for measuring spatial autocorrelation will be reviewed with an emphasis on the study and comparison of their robustness. Secondly, alternative methods will be proposed to robustly estimate the spatial autocorrelation. [less ▲]

Representations are a key factor in the development of a physically active lifestyle. In women, it is fundamental to verify if there are not wrong represnetations about physical activity because that could be an important barrier to any change. This workshop will propose several activities aiming to show how it is possible to increase the awareness of people about what is physical activity and how to accept to reach the international recommendations.

The univariate coefficient of variation (CV) is a widely used measure to compare the relative dispersion of a variable in several populations. When the comparison is based on $p$ characteristics however, side-by-side comparison of marginal CV's may lead to contradictions. Several multivariate coefficients of variation (MCV) have been introduced and used in the literature but, so far, their properties have not been much studied. Based on one of them, i.e. the inverse of the Mahalanobis distance between the mean and the origin, this talk intends to demonstrate the usefulness of MCV's in several domains (finance and analytical chemistry) as well as provide a complete inference toolbox for practitioners. Some exact and approximate confidence intervals are constructed, whose performance is analyzed through simulations. Several bias-correction methods, either parametric or not, are suggested and compared. Finally, since MCV's are used for comparison purposes, some test statistics are proposed for the homogeneity of MCV's in $K$ populations. Throughout the talk, the robustness of the techniques will be discussed. As a by-product, a test statistic allowing to reliably compare $K$ univariate CV's even in presence of outliers will be outlined. [less ▲]

The Sahelian's environment suffered many perturbations increasing the food insecurity risks. Since three decades, the environment suffered a intense and significant land deterioration (Warren A. And al., 2001). A lot of regreening actions have been developped in the Sahelian countries but some actions are most sustainable and the costs are lower than the other. The International Fund for Agricultural Development (IFAD) has developped some actions to strengthen the natural ressources management. The most important actions have been introduced from the mi-term of 1,980 (Sendzimir J. And al., 2011). These actions concerned the main water and soil conservation technics: Zaï; „contour“ stone bund; half-moons; permeable rock dams (Wesel A., Rath T., 2002). The paper attempts to answer about the following question: „what are the indirect and direct socioeconomic impacts of the natural ressources management in the Maradi’s region ?“. Moreover, Maradi is the historical area of the IFAD actions and illustrates some major causes of land degradation. The main causes are the increase of demography and agricultural areas. In fact, the demography and agricultural area of Maradi are seriously worrying: 8 children per women and the agricultural area is less than 1 hectare per household (Andres L., Lebailly Ph., 2013). The paper relates and describes the main anti-erosion technics. It compared also the cost-benefit analysis about the soil and water conservation technics. Finally, the report try to establish a key who links the technics with the context (soil, people, environment, agriculture, livestock) (Moussa Dit Kalamou M., 2015; Jasmien C.J. and al., 2013).

The Palaeolithic deposit of Caours, located in the Somme, is the only Eemian site in Northern Europe in interglacial context. This site show an incredible conservation of faunal remains spread out over a large area and a recurrence Human occupation. That gave us a large amount of data about this period of Neanderthal history. We now questioning about the choice of this locality and the spatial organisation of Neanderthal. Then, spatial analysis using the Geographic Information System (GIS) appear to being a useful tool to answer it. We show the consequent availability of water, prey and tool raw material. Neanderthalians was opportunistic hunters of cervidae. There has also eat a heavier prey as aurochs and rhino by trapping or scavenging. Then Neanderthal of Caours butchering with tool made in-situ eating the meat and the marrow. [less ▲]

Ethane is the most abundant non-methane hydrocarbon in the Earth's atmosphere and an important precursor of tropospheric ozone. Its monitoring is therefore crucial for the characterization of air quality and of the transport of tropospheric pollution. Ethane is also an indirect greenhouse gas, influencing the atmospheric lifetime of methane. The main sources of ethane are located in the northern hemisphere, and the dominating emissions are associated to production and transport of natural gas. A preliminary trend analysis was conducted using measurements performed in the Swiss Alps. Over the last two decades, the trend of ethane showed a decline of around 1% per year, thanks to a reduction of fugitive emissions of fossil fuel sources. However, a recent upturn potentially attributed to the massive exploitation of shale gas and tight oil reservoirs in North America was found. The goal is to investigate the presence and form of changes in trend functions using nonparametric techniques. The possible location of such changes is investigated. In addition, nonparametric estimation techniques are used to allow for nonlinear trend functions. Given the nonstandard nature of the measurements we rely on dependent wild bootstrap techniques to conduct inference on possible breaks in linear trends and on nonparametric trend functions.

Le syndrome psychotique chez l'enfant est un syndrome d'évolution neuro-développementale très fréquent dans l'enfance mais souvent diagnostiqué avec un retard de deux années ou davantage. Une bonne connaissance de ce qu'est « un syndrome psychotique » est indispensable pour les professionnels de l'enfance. D’autres modules antérieurs de formations sont proposés par l'auteur du document présent afin d'en donner connaissance. Le module de formation ici présenté donne des points de repères pour une « Évaluation du cadre des prises en charge » du syndrome psychotique du jeune enfant. On trouvera successivement : 1) une définition générale du syndrome psychotique — 2) le fondement général des prises en charge — 3) les différents niveaux des paramètres déterminant les prises en charge : 3A) l'enfant, 3B) les parents et la fratrie, 3C) l'école et les enseignants — 4) quelques pistes de propositions : 4A) pour les intervenants dans leur relation à l'enfant, 4B) pour les psychothérapeutes, 4C) pour les enseignants, 4D) pour les entretiens avec les parents — 5) des réflexions sur les réévaluations et l'interaction en réseau.
