Climate effects on agriculture are of increasing concern in both the scientific and policy communities because of the growing population and the greater uncertainty in the weather during growing seasons. Changes in production are directly linked to variations in temperature and precipitation during the growing season and often to the offseason changes in weather because of soil water storage to replenish the soil profile. This is not an isolated problem but one of worldwide interest because each country has concerns about their food security. The Agricultural Model Intercomparison and Improvement Project (AgMIP) was developed to evaluate agricultural models and intercompare their ability to predict climate impacts. In sub-Saharan Africa and South Asia, South America and East Asia, AgMIP regional research teams (RRTs) are conducting integrated assessments to improve understanding of agricultural impacts of climate change (including biophysical and economic impacts) at national and regional scales. Other AgMIP initiatives include global gridded modeling, data and information technology (IT) tool development, simulation of crop pests and diseases, site-based crop-climate sensitivity studies, and aggregation and scaling.

L’objectif de ce texte est d’utiliser le concept de ritournelle pour analyser la formation d’un groupe professionnel dans le champ des politiques d’emploi en Belgique : les conseillers emploi du FOREM. L’auteur commence par définir et opérationnaliser le concept, emprunté à Deleuze et Guattari, en suivant les apports des théories de la communication réflexive. Il esquisse brièvement le contexte politique et institutionnel au sein duquel le groupe professionnel apparaît. Ensuite, il analyse trois ritournelles professionnelles, trois procédés de territorialisation des identités professionnelles des conseillers emploi. Il précise, en conclusion, la complémentarité du concept de ritournelle avec celui de rhétorique professionnelle. [less ▲]

We propose a generalization of the Bloch sphere representation for arbitrary spin states. It provides a compact and elegant representation of spin density matrices in terms of tensors that share the most important properties of Bloch vectors. Our representation, based on covariant matrices introduced by Weinberg in the context of quantum field theory, allows for a simple parametrization of coherent spin states, and a straightforward transformation of density matrices under local unitary and partial tracing operations. It enables us to provide a criterion for anticoherence, relevant in a broader context such as quantum polarization of light. [less ▲]

En Belgique, la question de la sexualité des personnes incarcérées a rarement fait l’objet de recherches de la part des chercheurs en sciences humaines, particulièrement des criminologues. A partir d’informations obtenues auprès de 530 hommes incarcérés au sein de dix établissements pénitentiaires belges francophones, nous avons réalisé une étude de la sexualité en milieu carcéral perçue et vécue par les personnes détenues. S’appuyant ainsi sur le modèle de la privation tel que développé par Sykes (1958), notre recherche se fonde sur l’hypothèse principale suivante : « la privation de relations hétérosexuelles en prison engendre chez le détenu un sentiment de frustration et en réponse à ce sentiment, l’individu incarcéré cherche à s’adapter. Cette adaptation suit différentes trajectoires allant de pratiques sexuelles plus solitaires à des pratiques sexuelles de substitution impliquant un rapport à l’autre. Elle porte également sur les discours et les comportements des personnes dans un contexte carcéral particulier et est influencée non seulement par leurs perceptions mais aussi par leur vécu ». Considérant cette hypothèse générale, notre étude entendait ainsi dresser un portrait actualisé de la sexualité incarcérée qui dépasse les apparences et les discours officiels. Grâce à la mise en œuvre d’une méthodologie d’analyse quantitative, six objectifs plus spécifiques ont été investigués. Pour étudier les représentations et le vécu de la sexualité en milieu carcéral de notre échantillon, nous nous sommes d’abord appuyée sur les apports théoriques et scientifiques de la littérature spécifique. Ensuite, au moyen de traitements statistiques appliqués à notre base de données, nous avons cherché pour chaque axe des corrélations entre d’une part, les variables relatives aux représentations et vécus sexuels des détenus et d’autre part, des variables caractéristiques comme par exemple l’âge, la durée d’incarcération, l’existence d’un partenaire affectif extérieur, le bénéfice de visites en prison et la participation aux activités en détention,….

Integrating social and ethical concerns in innovation practice is a well-documented and debated issue in the United States and in Europe (namely through the EU-wide PACITA project). Related developments in other parts of the world are less discernible – at least to Westerns. Yet, as witnessed by the emergence of technology assessment (TA) in countries like Japan, TA and TA-like activities have a unique and long history and continue to play a role in contemporary STI processes (e.g. in the area of citizen engagement with nanotechnologies, or energy policy). Taking these observations as its entry point, this panel asks how STI governance is locally enacted in Asian knowledge-driven economies. Like their Western counterparts, nations like China, Indonesia, Japan, the Republic of Korea, Singapore, Taiwan, etc., have undergone, and continue to undergo, rapid science- and technology-driven industrialization. In these processes, TA and TA-like activities develop with STI policies and programs and typically do so in nation- and region-specific ways. To render these processes, policies, and programs visible, and understand their implications for STI governance, this panel will discuss contributions that: • Describe and conceptualize how TA and TA-like activities have emerged in Asian KBEs, and in what particular forms (e.g. academic and parliamentary TA programs, linked to certain technologies and/or actors, which methods are used and why, etc.). • Reflect how these activities has evolved with, sustained, and/or countered, STI policies on the regional, national, and international level. • Compare and contrast how TA is, or is not, institutionalized in Asian countries and regions, e.g. through initiatives to initiate or abolish various TA forms, such as health TA, early-warning TA, and parliamentary TA; and/or point to prospects for TA capacity building. • Situate the above processes within a broader theory of, and movement towards, new STI governance frameworks, such as anticipatory governance, responsible innovation, public engagement, and/or others. By placing the development in historical, sociological, and comparative perspective, the panel seeks to open a space for critical reflection on the potential, problems, and limitations of initiating TA in Asia and draw connections to STI governance processes in other KBEs across the globe.

In Niger Republic land issue is a concern to all parties acting in the rural area. The drought cycles of the last decades and the rapid increase of the population that doubles every ten years are determinant factors of degradation of the agricultural land of culture with as consequence the land and food insecurity of the households in particular in the region of Tahoua. Despite efforts by the government and its partners through the village land management programs and natural regeneration, land access difficulties persist particularly for women households. The objective being to assess and analyze the impact of land dynamics induced by the recovery of land in order to find some solutions to the problems of land insecurity and access and control of natural resources by households, a survey was conducted in two phases. The first in 2010 for a sample of 420 households in twenty villages selected through a stratified sampling. The second in 2012 for a sample of 84 households with 42 female heads of household from the first sample being associated with a group of 42 male heads of households for a specific gender analysis. It appears from this study that men households have an average land area about twice as large as that of female households .It was also found that the land is usually concentrated in the hands of older householders over 60 years. It is noticed that the inheritance is also one of the most dominant modes of access to land. The fragmentation and the expansion of croplands favor the emergence of fields beyond the northern boundary of crops dedicated to breeding. Finally, the last three years, agricultural production has generally fallen. The results of the analysis also show that unlike men, women household heads have less inputs, on the one hand, and little income, on the other hand. These female households derive their main income from the sale of animal products. This proves that women are the poorest households with limited access to natural resources. To fight against tenure insecurity and poverty of households recommendations and perspectives have been identified for the establishment of good governance of land resources, intensification of anti-erosion works by households with substantial resources and initiation of other additional research for sustainable development of the region.

We numerically and theoretically investigate the behavior of a granular gas driven by asymmetric plates. The injection of energy in the dissipative system differs from one side to the opposite one. We prove that the dynamical clustering which is expected for such a system is affected by the asymmetry. As a consequence, the cluster position can be fully controlled. This property could lead to various applications in the handling of granular materials in low-gravity environment. Moreover, the dynamical cluster is characterized by natural oscillations which are also captured by a model. These oscillations are mainly related to the cluster size, thus providing an original way to probe the clustering behavior. [less ▲]

Lead concentrations and isotope ratios from two speleothems from the Han-sur-Lesse cave in southern Belgium were measured in order to study the ability of speleothems to act as archives of atmospheric pollution. To address this aim we analyzed trace elemental Al and Pb compositions by LA-ICP-MS and ICP-MS as well as Pb isotopes by MC-ICP-MS. The results help to identify three intervals characterized by particularly high enrichment of Pb: from 1880 to 1905 AD, from 1945 to 1965 AD, and from 1975 to 1990 AD. The speleothem record shows similar changes as the known historical atmospheric pollution level in Belgium. Lead isotope ratios discriminate between Pb sources and confirm that coal and gasoline combustion, combined with regional metallurgical activities, were the predominant Pb pollution sources in the stalagmites during the last 250 years. This study opens possibilities to determine anthropogenic versus natural metal sources in well-dated speleothem archives. [less ▲]
