    The present document defines properties and usage of IoT and M2M technology in Contact Tracing.It introduces the method of Asynchronous Contact Tracing (ACT). ACT registers the presence of SARS-CoV-2 virus on IoT connected objects (waste water, or air conditioning filters, or dirty objects, or dirty cleaning tools, etc.) or connected locations (such as a shops, restaurants, corridors in a supermarket, sanitary facilities in a shopping mall, railway stations, airports terminals and gates, etc.) using Group Test (sometime called in the literature Pooling Test).ACT identifies contacts with IoT connected objects that have been contaminated by the SARS-CoV-2 virus and works in synergy with solutions designed for manual and digital contact tracing to identify and alert people who may have been infected by the virus. In case the object is suspected to host or have hosted the SARS-CoV-2 virus, ACT allows users that have been in contact with the object or visited the connected location to be informed.This shifts the paradigm from synchronously tracing the contacts of the people infected by COVID-19 to asynchronously tracing of contacts of materials (such as infected surfaces, waste-water, air-conditioning filters, etc.) that are hosting the SARS-CoV-2 virus.This enables people who have come into contact asynchronously with those particular materials to be alerted of a potential COVID-19 contagion, and, at the same time, it signals that one or more persons have been in contact with the material which is now spreading the SARS-CoV-2 virus.; Asynchronous Contact Tracing (ACT) traces the IoT connected object that may have been infected by the Covid-19 virus (or future pandemic viruses). This shifts the paradigm, from searching for a person in the process of infecting another to the tracing of both potential contamination and infections, and leveraging on the combination of the two information.The scope of this WI is to standardize the full support of Asynchronous Contact Tracing (ACT) by means of1) providing some examples of use and deployment of ACT by means of a few explanatory use cases.2) specifying the ACT method and its interaction with deployed contact tracing applications for human and systems. This includes the interaction with the different technologies used by non ACT contact tracing solutions.3) specifying the ACT system including application protocols and API.The new ACT method will require the use of existing ready-to-market IoT-based technology and well-established wireless network techniques, in particular the ones specified in the ETSI standards ecosystem. Moreover, it will preserve the user's privacy in accordance with GDPR and/or other regional requirements not requiring the transmission of any personal information by the user.

    Contribution à un site web; During the successive lockdowns caused by the Covid-19 pandemic, 80% of students around the world had to continue their courses online. However, videoconferencing while managing a continuous flow of emails can be exhausting and remote working can be difficult to cope with. A group of researchers, mainly from the Innovation, Technology, Economics & Management Laboratory (LITEM – Univ. Paris-Saclay, Univ. d’Évry, IMT-BS), followed a group of students at Université Paris-Saclay during the first lockdown in Spring 2020. Although some students managed to make the change well, many talked of ‘zoom burnout’ and of no longer being able to face being in front of their screens all day. In fact, whether an individual makes a successful transition to remote learning depends on an element which is often ignored - namely the ability to keep an open mind. [...]

    Project: EC | RESILOC (833671)

    The Second ENCORE European conference in October 2021 in Paris, France, has gathered two communities, the Risk Perception and Behaviour Survey of Surveyors (Risk-SoS) and the H2020-DRS01 Cluster on risk perception and adaptive behaviour (a grouping of several Horizon Europe – Disaster Resilient Societies projects, most notably RESILOC, BUILDERS, ENGAGE, LINKS, CORE and Risk PACC). During the Covid-19 pandemic lockdowns in 2020 and 2021 the monthly Risk-SoS webinars have been keeping the risk perception and adaptive behaviour research community together with panels on the role of theories in research on hazards adaptation, resilience and vulnerability. Topics were on risk perception and behaviour across challenges and time, across disciplines and methods, as well as panel and longitudinal approaches, and workshops on theories and methods to advance the design of a collective surveying approach with potentially common questions and answers’ scales to foster comparability. The Risk-SoS webinars have also been discussing the results of the Survey of Surveyors and sustaining the collective effort to build a harmonised approach for risk perception and adaptive behaviour assessment. In an hybrid format, the Second ENCORE conference has gathered 25 researchers and experts from 10 countries (Austria, Belgium, France, Germany, the Netherlands, Poland, Spain, Sweden, Switzerland and the United Kingdom) at the Ministry of Research in Paris, France.

    IPP PolicyBriefs n 74; Questions linked to the design and implementation of redistributive tax policies have occupied a growing position on the public agenda over recent years. Moreover, the fiscal pressures brought upon by the current coronavirus crisis will ensure that these issues maintain considerable political significance for years to come. In light of this importance, we present novel research on reforms of income tax systems. Our approach shows that tax reforms wherein the changes in individual tax burdens are larger for taxpayers with higher incomes are of particular interest. We denote such reforms as “monotonic” and show that, under this condition, it is possible to determine the “winners” and “losers” of a given tax reform. One can then conclude whether the monotonic reform is politically feasible, depending on whether a majority of individuals will benefit financially from the policy. An empirical analysis of tax reforms with a focus on the United States and France reveals that past reforms have, by and large, been monotonic. Our approach therefore enables us to test whether a given tax system admits a politically feasible reform and has direct policy relevance for the common types of taxation reforms undertaken by government authorities.

    The Conversation; COVID-19 cases have risen exponentially in Southeast Asia in the past few months – at one time deaths were increasing at the fastest pace in the world. With the advance of the Delta variant, the region and its 655 million population have now become a pandemic hotspot due to geographical, political and socioeconomic factors.

    Avis du Haut Conseil de Santé Publique (HCSP, France); International audience; Covid-19: Complementary recommendations on strategies to prevent the spread of SARS-CoV-2 in child care and school settings (HCSP, Avis et Rapports)Yannick Aujard, Anne Berger-Carbonne, Agathe Billette de Villemeur, Daniel Bley, Jean-Marc Brignon, Daniel Camus, Christian Chidiac, HCSP, Nicolas Eterradossi, Éric Gaffet, Jean-François Gehanno, Philippe Hartemann, Didier Lepelletier, Yves Lévi, Francelyne Marano, Philippe Minodier, Brigitte Moltrecht, Jean-Louis Roubaty, Gilles Salvat, Fabien Squinazi, Nicole VernazzaDate du document : 17/09/2020Date de mise en ligne : 27/05/2021https://www.hcsp.fr/Explore.cgi/AvisRapportsDomaine?clefr=1021The High Council of Public Health (HCSP) clarifies its recommendations of 9 September 2020 on strategies to prevent the spread of SARS-CoV-2 in childcare facilities and schools.The HCSP takes into consideration the fact that children are at low risk of severe disease and are poorly involved in the transmission of SARS-CoV-2. Transmission occurs mainly from adult to adult and from adult to child but rarely from child to child or from child to adult. Contaminations occur mainly within families or during social gatherings with a high density of people, outside schools. The wearing of masks by adults in primary school with children under 11 is mainly intended to protect children from contamination by asymptomatic adults who carry the virus. The HCSP recommends:to impose systematic use of a category 1 clothe mask that meets Afnor specifications for professionals in contact with the population;to consider that masks that do not meet Afnor category 1 specifications are not recommended for professionals in contact with children/students;to impose on children over 11 years of age to wear a category 1 mask that preferably meets Afnor specifications.not to consider an adult as “contact” if he/she wears a category 1 clothe mask meeting Afnor specifications or a medical mask when in contact with a child under 11 detected as positive case for Covid-19 and not wearing a mask.The HCSP also provides recommendations concerning contact-tracing in child-care and school and precise when a children/student should go back to school after having been tested positive for Covid-19.Lire en français :Covid-19 : Compléments sur les stratégies de prévention de la diffusion du SARS-CoV-2 en EAJE et milieu scolaire du 17 septembre 2020; Par cet avis complémentaire, le HCSP précise ses recommandations du 9 septembre 2020 concernant les stratégies de prévention de diffusion du SARS-CoV-2 en établissement d’accueil du jeune enfant (EAJE) et en milieu scolaire.Le HCSP prend en considération que les enfants sont peu à risque de forme grave et peu actifs dans la transmission du SARS-CoV-2. Le risque de transmission existe surtout d’adulte à adulte et d’adulte à enfant et rarement d’enfant à enfant ou d’enfant à adulte. Les transmissions surviennent surtout en intra-famille ou lors de regroupements sociaux avec forte densité de personnes en dehors des établissements scolaires. Le port du masque par les adultes dans les classes primaires accueillant des enfants de moins de 11 ans vise surtout à protéger les enfants d’une contamination par des adultes porteurs du virus et asymptomatiques. Le HCSP recommande de :rendre systématique le port préférentiel d’un masque grand public de catégorie 1 répondant aux spécifications de l’Afnor à destination de professionnels au contact de la population ;considérer que les masques grand public ne répondant pas aux spécifications de la catégorie 1 de l’Afnor ne sont pas recommandés pour les professionnels au contact des enfants/élèves ;rendre systématique pour les enfants de plus de 11 ans le port d’un masque grand public répondant de préférence aux spécifications de la catégorie 1 de l’Afnor.ne pas considérer un adulte encadrant comme contact s’il porte un masque grand public de catégorie 1 répondant aux spécifications de l’Afnor ou un masque à usage médical au contact d’un enfant de moins de 11 ans détecté positif Covid-19 ne portant pas de masque.Le HCSP émet aussi des recommandations concernant le contact-tracing dans ces structures et le retour d’éviction des enfants/élèves.
