    Documents de travail du Centre d'Economie de la Sorbonne 2023.17 - ISSN : 1955-611X; This study aims at connecting the behavioral corporate finance (micro level) perspective andcomplexity theory along with agent-based modelling in order to analyze the impact of selected behavioral managerial factors on aggregated data related to the financial market stability (macro level). Specifically, we want to explore whether subjective well-being (SWB) of corporate managers (CEOs) impacted their business decisions during the Covid-19 pandemic, and how it may be related to volatility of stock prices and the issue of financial stability during this critical period. Our study is based on a survey of 255 managers of companies listed on the Warsaw Stock Exchange in Poland over the period …. Using the results of this survey, we build an agent-based model (ABM) calibrated for the specific case of Poland to investigate how decision making of CEOs, stemming from their SWB, influence the stock prices and selected financial market dynamics indicators. The results of our study indicate that the excess volatility of stock prices may be a function of changes of SWB of managers, which in turn could lead to some crashes on the macro level with respect to financial stability.

    SIECRT is a dataset published on the Recherche Data Gouv data repository.; SIECRT is a new dataset focused on public health measures adopted by 26 small affiliated island economies in their fight against the Covid-19 pandemic, between January 1, 2020, and April 31, 2021, with some exceptions extending until October 30, 2021. This dataset stands out from previous ones by focusing on affiliated island territories, often overlooked in other databases. It includes eight public health measures, such as restrictions on gatherings, educational establishments, and international travel. Each measure is coded daily.; SIECRT est un nouveau jeu de données axé sur les mesures de santé publique adoptées par 26 petites économies insulaires affiliées dans leur lutte contre la pandémie de Covid-19, entre le 1er janvier 2020 et le 31 avril 2021, avec quelques exceptions s'étendant jusqu'au 30 octobre 2021. Ce jeu de données se distingue des précédents en se concentrant sur les territoires insulaires affiliés, souvent négligés dans d'autres bases de données. Il comprend huit mesures de santé publique, telles que les restrictions sur les rassemblements, les établissements éducatifs et les voyages internationaux. Chaque mesure est codée quotidiennement.

    Induced by the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the COVID-19 pandemic underlined the clear need for antivirals against coronaviruses. In an effort to identify new inhibitors of SARS-CoV-2, a screening of 824 extracts prepared from various parts of 400 plant species belonging to the Rutaceae and Annonaceae families was conducted using a cell-based HCoV-229E inhibition assay. Due to its significant activity, the ethyl acetate extract of the leaves of Clausena harmandiana was selected for further chemical and biological investigations. Mass spectrometry-guided fractionation afforded three undescribed phenolic lipids (1–3), whose structures were determined via spectroscopic analysis. The absolute configurations of 1 and 2 were determined by analyzing Mosher ester derivatives. The antiviral activity against SARS-CoV-2 was subsequently shown, with IC50 values of 0.20 and 0.05 µM for 2 and 3, respectively. The mechanism of action was further assessed, showing that both 2 and 3 are inhibitors of coronavirus entry by acting directly on the viral particle. Phenolic lipids from Clausena harmandiana might be a source of new antiviral agents against human coronaviruses.

    City Diplomacy Lab | Columbia Global Centers | Paris; How can cities and territories be transformed for an effective and sustainable environmental transition? How can we rethink the functioning of urban areas? How can we ease people’s lives?To tackle those challenges, I searched for an urban model that is anchored in modernity by its sustainability and humanity, not its technology. It led, in 2016, to the concept of the 15-minute city, a city model that is today known all around the world.I propose a new form of urban organization based on proximity. The idea is to enable each inhabitant to satisfy his essential needs (housing, work, access to healthcare, supplies, learning, and self-fulfillment) within 15 minutes of his home by active modes of transport (walking, cycling). Proximity is making people’s lives easier, more pleasant, less stressful and, at the same time, reduces the carbon footprint of urban systems. It’s an alternative to a metropolitan lifestyle that many people suffer from: time-consuming commutes, CO2 emissions, the omnipresence of the car in the urban space, air pollution, isolation, unhappiness, etc.

    This Policy Brief presents preliminary results from the BY-COVID project as part of its comprehensive, sustainable and evidence-informed plan to effectively promote and improve FAIR (Findability, Accessibility, Interoperability, and Reusability) and open data sharing in support for European preparedness for COVID-19 and other infectious diseases. The Brief also places the project and its results in the context of the upcoming EOSC Partnership, the development of the European Health Data Space (EHDS) and the European Health Emergency Preparedness and Response Authority (HERA).Policy paper in brief Authors: Niklas Blomberg (ELIXIR) ORCID: 0000-0003-4155-5910, Marieke Willems (ELIXIR) ORCID: 0000-0001-9664-6225, Corinne S.

Palagi (SIB) ORCID: 0000-0001-9062-6303, Martina Draščić Capar (CESSDA) ORCID: 0000-0001-8848-3008; As seen during the COVID-19 pandemic, and other infectious disease outbreaks, researchers, health care professionals and "citizens (in terms of consent to share)" need to store, document, share, access, analyse, link and process research and clinical data across disciplines and national borders in a coordinated response. Like other infectious disease outbreaks, such as haemorrhagic fevers (e.g. cholera), COVID-19 will remain a societal challenge beyond the immediate outbreak, considering its destructive and disruptive impact on healthcare systems and the global economy. In addition to SARS-CoV-2, the pathogen at the source of COVID-19, the risk from other emerging pathogens also persists, which will require similar concerted action to identify and characterise infections with pandemic potential, and enable rapid public health action to mitigate health and societal impacts. Provision of comprehensive open data on infectious agents and related diseases during outbreaks supports evidence-based decision-making across scientific, medical, public health and policy domains and promotes reproducibility of research outcomes. European readiness for future pandemics is of utmost importance, and whilst preparedness for such eventualities requires provisions for e.g. rapid vaccine production and public procurement for personal protective equipment - far outside the scope of BY-COVID - the ‘open data’ aspects is a key component that should be addressed to ensure the preparedness of infrastructure as part of existing frameworks such as the European Open Science Cloud (EOSC). Contributing to enhance data sharing and utility for streamlined local to global public health decision-making and action, as defined by the World Health Organisation (WHO) as a key objective in the Global genomic surveillance strategy. In pandemic times, the mobilisation of raw viral sequences and the identification and monitoring the spread of SARS-CoV-2 variants is particularly important. The BeYond-COVID (BY-COVID) project was funded by the European Union under the call “FAIR and open data sharing in support to European preparedness for COVID-19 and other infectious diseases” (HORIZON-INFRA-2021-EMERGENCY-01) and will run until 2024, to make COVID-19 data accessible to research scientists and others such as medical staff in hospitals or government officials. The world has generated vast amounts of data in response to the COVID-19 pandemic, and is still generating more. This data comes from many different sources, and identifying, connecting and integrating it for effective analysis is challenging on many fronts.

    The French Statistical Institute estimates that the monetary poverty rate was stable between 2019 and 2020, while several scientific and associative contributions note significant socioeconomic difficulties among some groups during the Covid­19 pandemic. Using a secondary analysis of nine quantitative and qualitative surveys collected by the National Council for Policies to Combat Poverty and Social Exclusion (CNLE) in 2021, we show that several social groups were exposed to precariousness of varying format, chronology and mechanisms. We develop implications for poverty measures, welfare inequalities, non­governmental solidarities and temporalities of poverty policies.

    Vision of Humanity; The effects of the Covid-19 pandemic crisis were significant, if not decisive, in Russia's war action against Ukraine, due to the egos of developed states in the face of the pandemic, the "open" crises of NATO and the European Union, and the favorable tempo for Russian military action against a Ukraine beyond Moscow's control.; Les effets de la crise de la pandémie Covid-19 ont été significatifs, sinon décisifs, dans l'action de guerre de la Russie contre l'Ukraine, en raison des égos des états développés face à la pandémie, des crises " ouvertes " de l'OTAN et de l'Union européenne, et du tempo favorable à une action militaire russe contre une Ukraine hors du contrôle de Moscou.
