Abstract

L’analyse des dépenses que les ménages français consacrent aux biens et aux services culturels et de communication permet de prendre la mesure des évolutions au cours des années 2000. Si elles ont diminué en 2006 par rapport à 2001 et ne représentent plus que 4 % du budget disponible contre 4,5 % cinq ans plus tôt, la structure des dépenses culture-médias s’est considérablement transformée. La numérisation des biens culturels a amplifié la transition vers une industrie de services. L’analyse confirme l’influence de l’âge, du niveau d’études, de la catégorie socioprofessionnelle et de la taille de la commune de résidence dans la part des dépenses qu’un ménage français consacre aux dépenses culturelles. Une approche typologique des dépenses identifie trois univers de consommation culturelle : la culture « traditionnelle », la culture de l’écran et la culture « jeune ».

Abstract

On retiendra que les publics de la culture, s’ils sont plus fréquemment que la moyenne des internautes avertis, ne privilégient pas particulièrement les usages culturels en ligne. La plupart d’entre eux étaient déjà adultes quand internet a conquis les foyers, si bien que leurs pratiques numériques se sont glissées dans leurs habitudes culturelles plus sur le mode de la complémentarité que de la substitution. Mais qu’en sera-t-il des générations qui font aujourd’hui vivre l’« internet juvénile » et qui construisent leur univers culturel largement à partir de la culture numérique ?

Abstract

Depuis cinquante ans, la structure des dépenses des ménages a considérablement évolué. La culture, les loisirs et les télécommunications font partie des postes dont la part relative au sein du budget des 27,4 millions de ménages français a progressé. Les données de la comptabilité nationale pour 2007 ont permis une analyse détaillée de l’évolution des dépenses culturelles et de la part des différents postes : biens et services culturels, matériels et biens et services liés aux équipements, télécommunications.

Abstract

L’exploitation par le DEPS des enquêtes communautaires sur l’utilisation des TIC par les ménages et les particuliers, coordonnées, harmonisées et publiées par Eurostat, permet de dresser un portrait comparatif et en tendances de l’équipement en TIC, des modes d’accès à l’internet des ménages dans l’UE- 27 selon leurs caractéristiques socio-démographiques. Elle met en lumière l’intensification des usages numériques des particuliers, élucide les facteurs de développement des TIC que sont les usages culturels et le commerce électronique de produits culturels, mais aussi la forte liaison entre accès aux TIC et commerce électronique dans l’Union européenne. Enfin, sont établis des tendances et facteurs d’usages convergents sur l’internet, la télévision et la téléphonie: disponibilité, temps d’usages, générations, praticité, etc. Dans cette cartographie de l’accès et de l’utilisation des TIC dans l’UE, la France occupe une position intermédiaire: plutôt en dessous de la moyenne de l’UE en termes d’accès ou de téléphonie mobile, elle est plutôt au-dessus de cette moyenne en termes d’usages et de commerce électronique.

Abstract

This book brings together eleven works by scholars within and beyond geography, to argue the case for a continued engagement with smallholder agricultural studies. The research detailed is largely empirical and draws on a wide spectrum of mixed qualitative and quantitative methodologies. The case studies cover a range of geographic locations, including Brazil, Burkina Faso, South Africa, Botswana, Malawi, Madagascar, Vietnam, and the USA, with greatest emphasis in sub-Saharan Africa. Key themes that emerge include the structural and relative nature of "smallholder" as a category, the dynamic reality of smallholder livelihoods, the importance of smallholder farming and land-use practices to questions of environmental sustainability, and the challenges of vulnerability and adaptation in contemporary human–environment systems. Overall these studies show that smallholder studies are more pertinent than ever, especially in the face of finite resources and global environmental change.

Abstract

In China, inequality in social welfare is of rising political concern. This case study analyzes the determinants of well-being of rural households in Hebei using a secondary panel data set (1986 to 2006). One key question is how well-being was affected by institutional changes in times of societal transition. Based on population grouping, the author analyzes poverty and income development. The study reveals impacts of new possibilities to provide labor outside the own farm on the allocation of households’ labor time and the stability of full- and part-time farming over time. The assessments ground on agricultural household models, microeconomic concepts of labor allocation, and welfare theories. Different methodologies, e.g. inequality decomposition or hazard analysis, are applied.

Abstract

Future buildings require not only energy efficiency but also proper building automation and control system functionalities in order to respond to the needs of occupants and energy grids. These development paths require a focus on occupant needs such as good indoor climate, easy operability, and monitoring. Another area to be tackled is energy flexibility, which is needed to make buildings responsive to the price signals of electricity grids with increasing amounts of fluctuating renewable energy generation installed both in central grids and at building sites. This Special Issue is dedicated to HVAC systems, load shifting, indoor climate, and energy and ventilation performance analyses in buildings. All these topics are important for improving the energy performance of new and renovated buildings within the roadmap of low energy and nearly zero energy buildings. To improve energy performance and, at the same time, occupant comfort and wellbeing, new technical solutions are required. Occupancy patterns and recognition, intelligent building management, demand response and performance of heating, cooling and ventilation systems are some common keywords in the articles of this Special Issue contributing to future highly performing buildings with reliable operation.

Abstract

This book on the sustainable use of soils and water addressed a variety of issues related to the utopian desire for environmental sustainability and the deviations from this scene observed in the real world. Competing interests for land are frequently a factor in land degradation, especially where the adopted land uses do not conform with the land capability (the natural use of soil). The concerns of researchers about these matters are presented in the articles comprising this Special Issue book. Various approaches were used to assess the (im)balance between economic profit and environmental conservation in various regions, in addition to potential routes to bring landscapes back to a sustainable status being disclosed.
