Data analysis plays an increasing role in research, scientific expertise and prospective studies. Multiple data sources are often available to estimate a key parameter or to test a hypothesis of scientific or societal interest. These data, obtained under different environmental conditions or based on different experimental protocols, are generally heterogeneous. Sometimes they are not even directly accessible and should be extracted from scientific articles or reports. However, a comprehensive analysis of the available data is essential to increase the accuracy of estimates, assess the validity of research conclusions and understand the origin of the variability of the experimental results. A quantitative synthesis of the data set available allows for a better understanding of the effects of explanatory factors and for evidence-based recommendations. Designed as a methodological guide, this book shows the interests and limitations of different statistical methods to analyze data from experimental networks and to perform meta-analyses. It is intended for engineers, students and researchers involved in data analysis in agronomy and environmental science. Our objective is to present the main statistical methods to analyze data from experimental networks and scientific publications. Each chapter exposes one or more methods and illustrates them with examples processed with the R software. Data and R codes are provided and commented in order to facilitate their adaptation to other situations. The codes can be reused from the KenSyn R package associated with this book.

Comment les acteurs publics, professionnels et citoyens contribuent-ils à reconfigurer l'état social en France ? À partir de nombreuses études de cas, cet ouvrage a pour ambition de mettre à jour les tendances à l'œuvre dans le champ de l'intervention sociale mais aussi les contradictions qui traversent l'action publique, ainsi que les fenêtres démocratiques qui s'ouvrent au cœur de ces contradictions. On constate ainsi que le contrôle social prend aujourd'hui des formes renouvelées, mais qu'il suscite aussi des modalités inédites de résistance de la part des professionnels. Le triomphe de l'éthique se fait au détriment d'un projet politique de grande envergure, tandis que la rationalisation gestionnaire qui caractérise l'évolution du management dans le champ du social, hypothèque la construction de politiques sociales audacieuses et attentives à la subjectivité des personnes. Pourtant, les citoyens disposent aussi, en particulier par le biais des mobilisations associatives et de la publicisation sur Internet, de nouveaux moyens pour se faire entendre, tenter de rééquilibrer les rapports de domination qu'ils subissent et contribuer à faire évoluer les institutions.
