The European response to COVID-19 has revealed an inconvenient truth. Despite having integrated public health concerns across all its policies – be it agriculture, consumer protection, or security –, the Union cannot directly act to save people’s lives. Only member states can do so. Yet when they adopted unilateral measures to counter the spread of the virus, those proved not only ineffective but also disruptive on vital supply chains, by ultimately preventing the flow of essential goods and people across the Union. These fragmented efforts in tackling cross-border health threats have almost immediately prompted political calls for the urgent creation of a European Health Union. Yet this call raises more questions than answers. With the aim to offer a rigorous and timely blueprint to decision-makers and the public at large, this Special Issue of the European Journal of Risk Regulation contextualizes such a new political project within the broader constitutional and institutional framework of EU public health law and policy. By introducing the Special, this paper argues that unless the envisaged Health Union will tackle the root causes of what prevented the Union from effectively responding to COVID-19 – the divergent health capacity across the Union –, it might fall short of its declared objective of strengthening the EU’resilience for cross-border health threats.

Introduction The scholarly monograph has been compared to the Hapsburg monarchy in that it seems to have been in decline forever! It was in 2002 that Stephen Greenblatt, in his role as president of the US Modern Language Association, urged his membership to recognise what he called a ‘crisis in scholarly publication’. It is easy to forget now that this crisis, as he then saw it, had nothing to do with the rise of digital technologies, e-publishing, or open access. Indeed, it puts his words in...

Grasp planning and most specifically the grasp space exploration is still an open issue in robotics. This article presents a data-driven oriented methodology to model the grasp space of a multi-fingered adaptive gripper for known objects. This method relies on a limited dataset of manually specified expert grasps, and uses variational autoencoder to learn grasp intrinsic features in a compact way from a computational point of view. The learnt model can then be used to generate new non-learnt gripper configurations to explore the grasp space. Comment: accepted at SYSID 2021 conference

International audience; It has been 35 years since Igbozurike and Raza (1983), and rural communities in Nigeria continue to face many of the challenges identified in the ARMTI seminar. Poverty and rural-urban migration remain widespread in Nigeria. Further issues of security and terrorism have also made their way into the array of problems facing rural communities in Nigeria. Therefore, the aim of this paper is to review the issues affecting the quality of life in 21st century rural Nigeria, in order to ascertain what has changed or remained the same since 1983. In achieving the study aim, the parameters used by Igbozurike and Raza (1983) will be linked with current literature on the quality of life in rural Nigeria. The paper will look at the following parameters: socioeconomic indicators, social services and infrastructure, nutritional status, population structure and mobility, institutional frameworks and the role of Agricultural Development Projects (ADPs).

SAD CT4 soulard@supagro.inra.fr Partie IV - Comment évaluer ces recherches ?; National audience; Depuis plus de vingt ans, les Régions qui ont été dotées d'une existence institutionnelle avec la loi de 1982, ont commencé à se préoccuper du développement économique des territoires qui relevait de leur responsabilité en misant sur l'enseignement supérieur et la recherche. Accompagnant cette montée des régions, la volonté d'accroître des synergies territorialisées entre acteurs de la recherche et du développement économique (R&D) a été affichée avec plus d'insistance en raison d'un pas supplémentaire franchi dans la conception paradigmatique des liens entre production scientifique et compétitivité économique. Face à cette volonté affichée par les gestionnaires de la recherche, divers dispositifs incitatifs ont été mis en place pour favoriser des coopérations élargies entre recherche et entreprise. Parmi ces programmes figure le programme PSDR Bourgogne qui a été mis en place en 2000 et qui associe un acteur national (INRA) à un acteur régional (Conseil Régional Bourgogne) dans une perspective de coproduction de connaissances scientifiques et opérationnelles. Son évaluation permet d'identifier et discuter des problèmes de méthode d'évaluation car il ne s'agit pas seulement d'apprécier les résultats obtenus par le programme au regard d'objectifs affichés au départ, mais d'évaluer les effets propres du dispositif gestionnaire mis en place pour faire fonctionner un programme partenarial en région. Le programme a t-il réussi à susciter ou renforcer des synergies entre acteurs du développement régional ? Moyennant quelles conditions de mise en œuvre et de validation de la participation des chercheurs et des acteurs socio-économiques ? Avec quels effets sur les acteurs et les territoires investis dans le programme ? Au terme de ses quatre ans de fonctionnement, l'évaluation de PSDR Bourgogne constitue un bon support de réflexion pour d'autres programmes qui voudraient le suivre dans ces finalités. Du point de vue de son fonctionnement le programme est assez exemplaire par le dispositif organisationnel qu'il a su mettre en place et qui agence un fonctionnement interactif entre des acteurs. Cet ensemble de synergies a permis de dynamiser un partenariat avec des acteurs du développement régional, tout en conservant l'exigence de qualité scientifique des recherches entreprises en partenariat. Du point de vue de ses résultats et de ses effets, PSDR Bourgogne a réussi à susciter et conduire des recherches sur les thèmes qui l’intéressent, et il a pu faire faire au milieu de recherche mobilisé des déplacements effectifs de pratiques dans le sens recherché. La mobilisation des acteurs non chercheurs au PSDR Bourgogne a supposé d'inventer des pratiques et des dispositifs ad-hoc. Au final, l'expérience de PSDR Bourgogne illustre bien que créer une dynamique de production des connaissances qui irrigue les milieux de la recherche et du développement régional, repose sur différents niveaux d'intermédiation qui, quand ils trouvent à s'agencer de manière coordonnée, génèrent alors des synergies vertueuses. Toutefois, on peut s'interroger sur le rapport entre les moyens mobilisés, la quantité de recherches réalisées et le niveau de déplacement obtenu. On peut les trouver trop coûteux sauf si on considère le programme comme un investissement gestionnaire destiné a fonctionner comme un incubateur jugé indispensable pour déplacer des normes professionnelles et favoriser le développement d'un milieu de recherche régional sur les thématiques concernées.

The bidirectional photometric properties of the surface of Mars describe how remote measurements of surface reflectance can be linked to hemispherical albedo used for energy balance calculations. A simple Lambert's law is frequently assumed for global data processing, even though several local studies have revealed the complexity of Mars surface phase functions. In this paper, we derive a mean Bidirectional Reflectance Distribution Function (BRDF) representative of widespread typical Martian terrains. OMEGA and CRISM orbital observations are used to provide observational constraints at solar wavelengths over a wide range of viewing conditions all over the planet. Atmospheric contribution is quantified and removed using a radiative transfer model. We observe a common phase behavior consisting of a 5%–10% backscattering peak and, outside the backscattering region, a 10%–20% reflectance increase with emergence angles. Consequently, nadir measurements of surface reflectance typically underestimate hemispherical reflectance, or albedo, by 10%. We provide a parameterization of our mean Mars surface phase function based on Hapke formalism (ω=0.85, θ=17, c=0.6, b=0.12, B0=1 and h=0.05), and quantify the impact of the diffuse illumination conditions which change surface albedo as a function of local time and season. Our average phase function can be used as a refinement compared to the Lambertian surface model in global data processing and climate modeling.

The agricultural sector jointly provides a series of marketed and non-marketed goods, among which environmental benefits play an increasingly important role. This positive characteristic of farming is acknowledged by the European Union's current policy with agri-environmental measures providing public financing of programs under several headings such as extensification, grassland maintenance, landscape, and nature protection. These policies are expected to be continued and even reinforced. They rely on voluntary agreements with farmers: entrants are compensated for complying with a package of prescribed farming practices designed to secure conservation goals. To be effective from an environmental perspective, uptake is a key factor.
