    Various pro-cycling policies emerged around the world with the outbreak of the Covid-19 pandemic. France experimented with a €50 bike repair subsidy. Our questionnaire survey (n = 7343) focuses on beneficiaries’ sociological profiles. Despite its success in quantitative terms, the repair subsidy benefited more regular cyclists—who cycle daily—and people who are confident cycling in urban areas. Women were more likely to benefit than men, and people in low-income households more than those in high-income households. Because these populations are usually underrepresented among cyclists in France, the scheme may appear to have reduced inequities in cycling. However, the scheme could have reached out more to the low-income population who were largely unaware of it. This selectivity is partly explained by awareness of the subsidy, which is lower among the younger and the less educated part of the population. Our survey shows that the scheme is selective primarily because of its design. It would have been necessary to accompany it with measures specifically designed for vulnerable groups.

    National audience; Using data collected from one of the most popular ridesharing platforms, we illustrate how mobility has changed after the exit from the Covid-19 induced confinement. We measure the impact of the Covid-19 outbreak on the level of mobility and the price of ridesharing. Finally, we show that the pandemic has exacerbated ethnic discrimination. Our results suggest that a decision-maker encouraging the use of ridesharing during the pandemic should account for the impact of the perceived health risks on ridesharing prices and should find ways to ensure fair access.

    Introduction: The Covid-19 health crisis and the attendant pro-bicycle policies have accelerated the development of urban cycling worldwide. Bicycle traffic flows have generally been well documented, with particular focus on utilitarian trips during lockdowns. However, little research has examined the profiles of social groups affected by changes in bicycle use. That is the purpose of this article, which examines the socio-spatial factors behind changes in utilitarian and recreational cycle use.Methods: The study is based on a nationwide questionnaire completed by 7343 cyclists in France between May and October 2021. The analyses are based on bivariate treatments, tests of independence, logistic regressions, and additional comments by some respondents (n = 1594).Results: Our results show both utility and leisure cycling were more likely to have increased than decreased over the period under study. However, while utility practice was driven by fear of Covid-19 but inhibited by teleworking, recreational practice was driven by both working-at-home and by the desire to get out for some physical exercise. Compensatory phenomena, blurring the boundary between leisure and utility, are perceptible. Reductions in both the gender gap and the income gap in bicycle use are measured. However, since these were mainly forced changes and since inequalities in access to cycling persist, the narrowing of these gaps cannot be interpreted as steps toward gender or class equality.Conclusions: The article recommends further research to assess the persistence of observed changes in leisure and utility cycling. At the same time, it warns against the pitfall of considering that a reduction in inequalities in cycling practices implies a reduction in social inequalities. International audience

    International audience; The sustainable consumption and integration of digital solutions with respect to sustainable consumption have been encouraged by the new European circular economy action plan. Digital adoption has been accelerated by the COVID-19 pandemic; companies have been challenged to rapidly adapt to the constant evolution of consumer needs and expectations, leading to valuable insights into the advancement of green business practices and a consequent rethinking of their business model. The purpose of this paper is to investigate the major shifts in sustainable consumer behavior on the Romanian retail market within the context of the Green European Deal, and retailers’ priorities in agilely adapting to these significant evolutions. Based on a comprehensive literature review on these major shifts and significant evolutions at the national and international levels, a quantitative study was carried out to evaluate the Romanian retail market and identify the major challenges faced by retailers in dealing with the new set of priorities. The data collection was conducted via a survey used in the retail environment, applied within a Romanian supermarket chain. The Romanian retail sector has a particular configuration, which may have an impact upon the study’s generalizability. Located in Central and Eastern Europe at the crossroads of the EU, the Commonwealth of Independent States (CIS), and the Middle East, Romania is a leading destination for foreign direct investment, and it is recognized for the similarities of its distribution and sales channels, the range of its retail outlets, and the local retail market dominance on the Big Box segment by reputed major retailers. A spectacular evolution is recorded in Romania’s e-commerce market, including from the point of view of the long-standing and memorable traditional relationship between Romania and China which was confirmed more recently by Romanian consumers who prefer to buy online from stores in China. Our consumer research provides retailers with deep consumer insights with regard to their priorities in their agile adaptation. According to our research, Romanian consumers are environmentally concerned consumers, displaying an increased awareness about the important role they play with respect to impacting sustainable production and consumption by adopting green purchase behavior. Our study also points to the fact that retailers, although faced with challenges in targeting consumers with customized messages to reinforce their brand perception on sustainability issues, do pay considerable attention to sustainability as a personal value embraced by consumers and are willing to focus on digitizing their business processes to enable new, sustainable business models.

    This paper analyses the changes on the maritime network before and after the Covid-19 outbreak. Using a large sample of vessel movements between ports, we show a decrease in the global maritime connectivity and significant differences between ports and inter-port links. Furthermore, we find that Covid-19 mitigation measures implemented by governments affected regional port hierarchies differently, with a reduction in port concentration in Europe and Africa and an increase in Asia and North America. Globally, very large ports and small but densely inter-connected ones resisted better to the crisis than the others, while small transshipment hubs and bridges appear to have been more negatively impacted. These findings have implications for the design of more resilient port strategies and transport policies by states and firms.

    International audience; To face the new challenges caused by modern industry, logistics operations managers need to focus more on integrating sustainability goals, adapt to unexpected disruptions and find new strategies and models for logistics management. The COVID-19 pandemic has proven that unforeseen fragilities, negatively affecting the supply chain performance, can arise rapidly, and logistics systems may confront unprecedented vulnerabilities regarding network structure disruption and high demand fluctuations. The existing studies on a resilient logistics network design did not sufficiently consider sustainability aspects. In fact, they mainly addressed the independent planning of decision-making problems with economic objectives. To fill this research gap, this paper concentrates on the design of resilient and sustainable logistics networks under epidemic disruption and demand uncertainty. A two-stage stochastic mixed integer programming model is proposed to integrate key decisions of location–allocation, inventory and routing planning. Moreover, epidemic disruptions and demand uncertainty are incorporated through plausible scenarios using a Monte Carlo simulation. In addition, two resiliency strategies, namely, capacity augmentation and logistics collaboration, are included into the basic model in order to improve the resilience and the sustainability of a logistics chain network. Finally, numerical examples are presented to validate the proposed approach, evaluate the performance of the different design models and provide managerial insights. The obtained results show that the integration of two design strategies improves resilience and sustainability.

    International audience; The increasing impacts of climate change, coupled with the Greta Thunberg effect, the findings of the Intergovernmental Panel on Climate Change (IPCC) reports, and varied environmental policy documents, are pointing to the need for urgent and cohesive climate action and mitigation frameworks. One potent solution, gaining global acceptance, is that of the Green New Deal (GND), positioned as a radical rethinking of political and economic structures in view of pushing sustainability at the forefront of national, regional, and global issues. With the model rapidly gaining ground in various geographies, and in different forms in view of contextualization needs, there is a need to better understand its evolution, knowledge structures, and trends. This paper thus sets forth to provide an understanding of the evolution and implementation of GND through a bibliometric analysis and science mapping techniques using VOSviewer and CiteSpace to identify the thematic focus of 1174 articles indexed in the Web of Science since 1995. To understand the thematic evolution of the field over time, we divided the study period into three sub-periods, namely 1995–2014, 2015–2019, and 2020–2021. These sub-periods were determined considering important milestones related to GNDs. Term co-occurrence analyses were then conducted to understand thematic focus and associated trends. Also, co-citation analysis and bibliographic coupling were other methods applied to identify major sources, authors, publications, and countries that have made more contributions to the development of research on GNDs. The findings of this paper can help both researchers and policy makers understand the evolution and trends of GNDs to better formulate GNDs strategies and policies in accordance with varying needs and geographies.

    During the first wave of the COVID-19 pandemic, some French regions were more affected than others. To relieve those areas most affected, the French government organized transfers of critical patients, notably by plane or helicopter. Our objective was to investigate the impact of such transfers on the pulse oximetric saturation (SpO2)-to-inspired fraction of oxygen (FiO2) ratio among transferred critical patients with COVID-19. We conducted a retrospective study on medical and paramedical records. The primary endpoint was the change in SpO2/FiO2 during transfers. Thirty-eight patients were transferred between 28 March and 5 April 2020, with a mean age of 62.4 years and a mean body mass index of 29.8 kg/m2. The population was 69.7% male, and the leading medical history was hypertension (42.1%), diabetes (34.2%), and dyslipidemia (18.4%). Of 28 patients with full data, we found a decrease of 28.9 points in SpO2/FiO2 (95% confidence interval, 5.8 to 52.1, p = 0.01) between the starting and the arrival intensive care units (SpO2/FiO2, 187.3 ± 61.3 and 158.4 ± 62.8 mmHg, respectively). Air medical transfers organized to relieve intensive care unit teams under surging conditions during the first COVID wave were associated with significant decreases in arterial oxygenation.

    International audience; Using Sentinel-5P data, this study investigated the magnitude of change in the concentration of air pollutants (NO2, HCHO, SO2, O3, CO, and aerosol index) in the air of ten cities and urban areas of the French region of Grand Est as a result of the first lockdown imposed between March 17, 2020 and May 11, 2020. The results showed that the air quality in the urban environments of Grand Est improved significantly compared to the same period in 2019 without lockdown. NO2, O3, aerosol index and CO were the pollutants that exhibited maximum reductions by an average of -33.98%, -5.94%, -26.82% and -0.66%, respectively (the observed maximum decreases were -54.7%, -7.7%, -13.1%, and -5.3%, respectively). The largest decrease occurred in the Public Establishments of Inter-municipal Cooperation (EPCI, in French: Établissement public de coopération intercommunale) areas of Eurométropole de Strasbourg, CA Colmar, and CA Mulhouse Alsace. The maximum decrease in air pollution first occurred in land cover classes close to cities, followed by built-up urban areas. In this study, a global depollution index known as the atmospheric clearance index (ACI) was developed, which involved several air pollution parameters, and quantitatively analyzed the decrease in contamination levels of the atmosphere in this region. In addition, the correlation between the novel ACI and other population and economic development indices was studied. The results indicated that there was a negative and statistically significant correlation between ACI and population density, gross domestic product, gross value added (GVA) at basic prices, number of employees, and active enterprises.

    International audience; A variety of public economic policy measures have been designed and implemented in an effort to enable SMEs to limit damages resulting from the adverse sanitary and economic shocks associated with COVID-19. The originality of our study is to propose a rating of the various economic policy measures, the rating being expressed by SMEs owners conditional to their business expectations. In so doing, our contribution is to highlight the policy measures to be implemented in order to support resilient and ambitious ventures with the most positive prospects, which are likely to contribute the most to economic recovery. We exploit an original and rich dataset derived from a survey conducted in May 2020 among a representative sample of more than 2100 Belgian (Walloon) SMEs. The Belgian experience is remarkable because the wide variety of measures it undertook echoes many of the measures taken by OECD countries. Our results suggest that the respondents have an overall positive evaluation of the various economic and social policy measures implemented by the Belgian authorities. More importantly, the rating by SME owners with the most favorable expectations are, however, significantly different than their counterpart. Measures helping firms to maintain their workforce are particularly highly rated by firms with the best prospects. It also appears that those firms prefer short-term and transitory measures.

    Various pro-cycling policies emerged around the world with the outbreak of the Covid-19 pandemic. France experimented with a €50 bike repair subsidy. Our questionnaire survey (n = 7343) focuses on beneficiaries’ sociological profiles. Despite its success in quantitative terms, the repair subsidy benefited more regular cyclists—who cycle daily—and people who are confident cycling in urban areas. Women were more likely to benefit than men, and people in low-income households more than those in high-income households. Because these populations are usually underrepresented among cyclists in France, the scheme may appear to have reduced inequities in cycling. However, the scheme could have reached out more to the low-income population who were largely unaware of it. This selectivity is partly explained by awareness of the subsidy, which is lower among the younger and the less educated part of the population. Our survey shows that the scheme is selective primarily because of its design. It would have been necessary to accompany it with measures specifically designed for vulnerable groups.

    National audience; Using data collected from one of the most popular ridesharing platforms, we illustrate how mobility has changed after the exit from the Covid-19 induced confinement. We measure the impact of the Covid-19 outbreak on the level of mobility and the price of ridesharing. Finally, we show that the pandemic has exacerbated ethnic discrimination. Our results suggest that a decision-maker encouraging the use of ridesharing during the pandemic should account for the impact of the perceived health risks on ridesharing prices and should find ways to ensure fair access.

    Introduction: The Covid-19 health crisis and the attendant pro-bicycle policies have accelerated the development of urban cycling worldwide. Bicycle traffic flows have generally been well documented, with particular focus on utilitarian trips during lockdowns. However, little research has examined the profiles of social groups affected by changes in bicycle use. That is the purpose of this article, which examines the socio-spatial factors behind changes in utilitarian and recreational cycle use.Methods: The study is based on a nationwide questionnaire completed by 7343 cyclists in France between May and October 2021. The analyses are based on bivariate treatments, tests of independence, logistic regressions, and additional comments by some respondents (n = 1594).Results: Our results show both utility and leisure cycling were more likely to have increased than decreased over the period under study. However, while utility practice was driven by fear of Covid-19 but inhibited by teleworking, recreational practice was driven by both working-at-home and by the desire to get out for some physical exercise. Compensatory phenomena, blurring the boundary between leisure and utility, are perceptible. Reductions in both the gender gap and the income gap in bicycle use are measured. However, since these were mainly forced changes and since inequalities in access to cycling persist, the narrowing of these gaps cannot be interpreted as steps toward gender or class equality.Conclusions: The article recommends further research to assess the persistence of observed changes in leisure and utility cycling. At the same time, it warns against the pitfall of considering that a reduction in inequalities in cycling practices implies a reduction in social inequalities. International audience

    International audience; The sustainable consumption and integration of digital solutions with respect to sustainable consumption have been encouraged by the new European circular economy action plan. Digital adoption has been accelerated by the COVID-19 pandemic; companies have been challenged to rapidly adapt to the constant evolution of consumer needs and expectations, leading to valuable insights into the advancement of green business practices and a consequent rethinking of their business model. The purpose of this paper is to investigate the major shifts in sustainable consumer behavior on the Romanian retail market within the context of the Green European Deal, and retailers’ priorities in agilely adapting to these significant evolutions. Based on a comprehensive literature review on these major shifts and significant evolutions at the national and international levels, a quantitative study was carried out to evaluate the Romanian retail market and identify the major challenges faced by retailers in dealing with the new set of priorities. The data collection was conducted via a survey used in the retail environment, applied within a Romanian supermarket chain. The Romanian retail sector has a particular configuration, which may have an impact upon the study’s generalizability. Located in Central and Eastern Europe at the crossroads of the EU, the Commonwealth of Independent States (CIS), and the Middle East, Romania is a leading destination for foreign direct investment, and it is recognized for the similarities of its distribution and sales channels, the range of its retail outlets, and the local retail market dominance on the Big Box segment by reputed major retailers. A spectacular evolution is recorded in Romania’s e-commerce market, including from the point of view of the long-standing and memorable traditional relationship between Romania and China which was confirmed more recently by Romanian consumers who prefer to buy online from stores in China. Our consumer research provides retailers with deep consumer insights with regard to their priorities in their agile adaptation. According to our research, Romanian consumers are environmentally concerned consumers, displaying an increased awareness about the important role they play with respect to impacting sustainable production and consumption by adopting green purchase behavior. Our study also points to the fact that retailers, although faced with challenges in targeting consumers with customized messages to reinforce their brand perception on sustainability issues, do pay considerable attention to sustainability as a personal value embraced by consumers and are willing to focus on digitizing their business processes to enable new, sustainable business models.

    This paper analyses the changes on the maritime network before and after the Covid-19 outbreak. Using a large sample of vessel movements between ports, we show a decrease in the global maritime connectivity and significant differences between ports and inter-port links. Furthermore, we find that Covid-19 mitigation measures implemented by governments affected regional port hierarchies differently, with a reduction in port concentration in Europe and Africa and an increase in Asia and North America. Globally, very large ports and small but densely inter-connected ones resisted better to the crisis than the others, while small transshipment hubs and bridges appear to have been more negatively impacted. These findings have implications for the design of more resilient port strategies and transport policies by states and firms.

    International audience; To face the new challenges caused by modern industry, logistics operations managers need to focus more on integrating sustainability goals, adapt to unexpected disruptions and find new strategies and models for logistics management. The COVID-19 pandemic has proven that unforeseen fragilities, negatively affecting the supply chain performance, can arise rapidly, and logistics systems may confront unprecedented vulnerabilities regarding network structure disruption and high demand fluctuations. The existing studies on a resilient logistics network design did not sufficiently consider sustainability aspects. In fact, they mainly addressed the independent planning of decision-making problems with economic objectives. To fill this research gap, this paper concentrates on the design of resilient and sustainable logistics networks under epidemic disruption and demand uncertainty. A two-stage stochastic mixed integer programming model is proposed to integrate key decisions of location–allocation, inventory and routing planning. Moreover, epidemic disruptions and demand uncertainty are incorporated through plausible scenarios using a Monte Carlo simulation. In addition, two resiliency strategies, namely, capacity augmentation and logistics collaboration, are included into the basic model in order to improve the resilience and the sustainability of a logistics chain network. Finally, numerical examples are presented to validate the proposed approach, evaluate the performance of the different design models and provide managerial insights. The obtained results show that the integration of two design strategies improves resilience and sustainability.

    International audience; The increasing impacts of climate change, coupled with the Greta Thunberg effect, the findings of the Intergovernmental Panel on Climate Change (IPCC) reports, and varied environmental policy documents, are pointing to the need for urgent and cohesive climate action and mitigation frameworks. One potent solution, gaining global acceptance, is that of the Green New Deal (GND), positioned as a radical rethinking of political and economic structures in view of pushing sustainability at the forefront of national, regional, and global issues. With the model rapidly gaining ground in various geographies, and in different forms in view of contextualization needs, there is a need to better understand its evolution, knowledge structures, and trends. This paper thus sets forth to provide an understanding of the evolution and implementation of GND through a bibliometric analysis and science mapping techniques using VOSviewer and CiteSpace to identify the thematic focus of 1174 articles indexed in the Web of Science since 1995. To understand the thematic evolution of the field over time, we divided the study period into three sub-periods, namely 1995–2014, 2015–2019, and 2020–2021. These sub-periods were determined considering important milestones related to GNDs. Term co-occurrence analyses were then conducted to understand thematic focus and associated trends. Also, co-citation analysis and bibliographic coupling were other methods applied to identify major sources, authors, publications, and countries that have made more contributions to the development of research on GNDs. The findings of this paper can help both researchers and policy makers understand the evolution and trends of GNDs to better formulate GNDs strategies and policies in accordance with varying needs and geographies.

    During the first wave of the COVID-19 pandemic, some French regions were more affected than others. To relieve those areas most affected, the French government organized transfers of critical patients, notably by plane or helicopter. Our objective was to investigate the impact of such transfers on the pulse oximetric saturation (SpO2)-to-inspired fraction of oxygen (FiO2) ratio among transferred critical patients with COVID-19. We conducted a retrospective study on medical and paramedical records. The primary endpoint was the change in SpO2/FiO2 during transfers. Thirty-eight patients were transferred between 28 March and 5 April 2020, with a mean age of 62.4 years and a mean body mass index of 29.8 kg/m2. The population was 69.7% male, and the leading medical history was hypertension (42.1%), diabetes (34.2%), and dyslipidemia (18.4%). Of 28 patients with full data, we found a decrease of 28.9 points in SpO2/FiO2 (95% confidence interval, 5.8 to 52.1, p = 0.01) between the starting and the arrival intensive care units (SpO2/FiO2, 187.3 ± 61.3 and 158.4 ± 62.8 mmHg, respectively). Air medical transfers organized to relieve intensive care unit teams under surging conditions during the first COVID wave were associated with significant decreases in arterial oxygenation.

    International audience; Using Sentinel-5P data, this study investigated the magnitude of change in the concentration of air pollutants (NO2, HCHO, SO2, O3, CO, and aerosol index) in the air of ten cities and urban areas of the French region of Grand Est as a result of the first lockdown imposed between March 17, 2020 and May 11, 2020. The results showed that the air quality in the urban environments of Grand Est improved significantly compared to the same period in 2019 without lockdown. NO2, O3, aerosol index and CO were the pollutants that exhibited maximum reductions by an average of -33.98%, -5.94%, -26.82% and -0.66%, respectively (the observed maximum decreases were -54.7%, -7.7%, -13.1%, and -5.3%, respectively). The largest decrease occurred in the Public Establishments of Inter-municipal Cooperation (EPCI, in French: Établissement public de coopération intercommunale) areas of Eurométropole de Strasbourg, CA Colmar, and CA Mulhouse Alsace. The maximum decrease in air pollution first occurred in land cover classes close to cities, followed by built-up urban areas. In this study, a global depollution index known as the atmospheric clearance index (ACI) was developed, which involved several air pollution parameters, and quantitatively analyzed the decrease in contamination levels of the atmosphere in this region. In addition, the correlation between the novel ACI and other population and economic development indices was studied. The results indicated that there was a negative and statistically significant correlation between ACI and population density, gross domestic product, gross value added (GVA) at basic prices, number of employees, and active enterprises.

    International audience; A variety of public economic policy measures have been designed and implemented in an effort to enable SMEs to limit damages resulting from the adverse sanitary and economic shocks associated with COVID-19. The originality of our study is to propose a rating of the various economic policy measures, the rating being expressed by SMEs owners conditional to their business expectations. In so doing, our contribution is to highlight the policy measures to be implemented in order to support resilient and ambitious ventures with the most positive prospects, which are likely to contribute the most to economic recovery. We exploit an original and rich dataset derived from a survey conducted in May 2020 among a representative sample of more than 2100 Belgian (Walloon) SMEs. The Belgian experience is remarkable because the wide variety of measures it undertook echoes many of the measures taken by OECD countries. Our results suggest that the respondents have an overall positive evaluation of the various economic and social policy measures implemented by the Belgian authorities. More importantly, the rating by SME owners with the most favorable expectations are, however, significantly different than their counterpart. Measures helping firms to maintain their workforce are particularly highly rated by firms with the best prospects. It also appears that those firms prefer short-term and transitory measures.
