Analysis of COVID-19 Lockdown to Understand Air Pollution Processes and Their Impacts on Health: A Case Study in the Western Balkans

The effect of COVID-19 lockdown (LD) on many ambient air pollutants (NO, NO2, PM2.5, PM10, O3 and SO2) was assessed for the first time in the Western Balkans with an innovative approach that evaluates a variety of factors including the stringency of the LD measures, the type of location, the pollution sources, the correlation with traffic fluxes and the meteorology. To that end, observations from 10 urban sites were compared with historical time series. The time window 1 February–30 May 2020 was classified in sub-periods on the basis of the stringency of the circulation restrictions. NO2 and O3 are the pollutants most affected by restrictions to population circulation due to lockdown during the first phase of the COVID-19 pandemic, and are well correlated with traffic fluxes. A reduction in fine particulate matter (PM2.5 and PM10) concentrations is observed in all sites only during the full LD periods, while the relation between SO2 average and maximum hourly concentrations and LD periods in industrial and traffic sites vary from site to site. The reduction in NO2 concentrations during the LD resulted in a reduction in mortality associated with air pollution in the largest cities, while the interpretation of the changes in O3 and particulate matter is less clear.

Changes in health, lifestyle, and wellbeing of children with type 1 diabetes and their parents during the pandemic

ObjectiveThe COVID-19 pandemic restrictions have substantially affected people’s health and rapidly changed their daily routines. This is a prospective study that investigated the impact of the pandemic on primary school children with Type 1 diabetes and their parents during the first lockdown in Kuwait.MethodsA questionnaire battery related to mental health, well-being, and lifestyle was administered at baseline in Summer 2019 (face-to-face, at a diabetes outpatient clinic) and at follow-up during lockdown in Summer 2020 (via telephone, in adherence with COVID-19 restrictions). Data were collected for 70 dyads with children aged 9–12 years.ResultsSignificant differences were found in most scores for both children and parents. Their mental health worsened to a higher level of depression, anxiety, stress, and a poor level of wellbeing. The average scores on the follow-up tests fell within a clinical range on these measures. Significant differences in their lifestyle, compared to before the lockdown, included decreased levels of physical activity and lower healthy core nutritional intake.ConclusionsOur findings indicate that the COVID-19 lockdown has had a significant psychological and possibly physiological impact on children with Type 1 diabetes and their parents. We conclude that there is a need for mental health support services focusing on these groups. Although full lockdown restrictions will have stopped in the past year, post-pandemic stressors may be expected to continue to adversely affect this cohort.

Current out of pocket care costs among HIV and hypertension co-morbid patients in urban and peri-urban Uganda.

Despite improvements to the cascade of HIV care in East Africa, access to care for non-communicable disease co-morbidities like hypertension (HTN) remains a persistent problem. The integration of care for these conditions presents an opportunity to achieve efficiencies in delivery as well as decrease overall costs for patients. This study aims to build evidence on the burden of current out-of-pocket costs of care among HIV-HTN co-morbid patients. We administered a pre-tested, cross-sectional, out-of-pocket cost survey to 94 co-morbid patients receiving HIV care from 10 clinics in the Wakiso and Kampala districts of Uganda from June to November 2021. The survey assessed socio-demographic characteristics, direct medical costs (e.g., medications, consultations), indirect costs (e.g., transport, food, caregiving), and economic costs (i.e., foregone income) associated with seeking HIV and HTN care, as well as possible predictors of monthly care costs. Patients were sampled both during a government-imposed nation-wide full COVID-19 lockdown (n = 30) and after it was partially lifted (n = 64). Median HIV care costs constitute between 2.7 and 4.0% of median monthly household income, while HTN care costs are between 7.1 to 7.9%. For just under half of our sample, the median monthly cost of HTN care is more than 10% of household income, and more than a quarter of patients report borrowing money or selling assets to cover costs. We observe uniformly lower reported costs of care for both conditions under full COVID-19 lockdown, suggesting that access to care was limited. The main predictors of monthly HIV and HTN care costs varied by disease and costing perspective. Patient out of pocket costs of care for HIV and HTN were substantial, but significantly lower during the 2021 full COVID-19 lockdown in Uganda. New strategies such as service integration need to be explored to reduce these costs.

Exemplifying successful sports event amidst the pandemic: the case of the Turkish women's football super league

Objective: The aim of this study is to define the COVID-19 positivity rate, transmission routes and clinical symptoms in the group of female football players competing in the Turkish Women's Football Super League, where the bubble protocol was implemented during the full lockdown period when the cases peaked. Material and Methods: A retrospective observational study was carried out to include a total of 557 participants during the Turkish Women's Football Super League 3‐week event (April 17-May 5, 2021). This event was held within the scope of the bubble protocol developed for sports events during the full lockdown period of the pandemic. Regular reverse transcriptase PCR (RT-PCR) screenings were carried out as part of a standard procedure (48-72 hours prior to hotel check-in, upon arrival, and the day before matches) to assess the possible presence of the COVID-19 virus carriage. Results: In the pre-arrival test, COVID-19 was detected in 5.03% of football players (19/377). A positivity rate of 0.27% (1/367) was found in football players at the entrance to the hotel facilities. Of the tests performed to footballers during the "Bubble", COVID-19 has been detected in 0.54% (2/367). Tests of 1 team manager and 2 referees, who were in the "bubble protocol" but not in contact with players, were positive. All 6 detected cases were asymptomatic. 5 cases later showed flu-like symptoms. It was revealed that 5 out of 6 cases had contact with a positive case before the tournament. Conclusion: The bubble protocol, which includes testing, advanced hygiene, social distancing and daily symptom monitoring strategies can minimize the transmission of COVID-19 and provide a safe environment for sports organizations.

Weight gain, new-onset overweight or obesity, and their influencing factors during the social distancing era of the COVID-19 pandemic

The prevalence of obesity is gradually increasing in South Korea, and the coronavirus disease 2019 (COVID-19) pandemic has accelerated the weight gain. In response to COVID-19, South Korea implemented targeted distancing measures based on the number of COVID-19 cases, rather than a full lockdown. This study focused on two subgroups that influence the rise in obesity prevalence during the early stages of the COVID-19 pandemic and explored the factors contributing to rapid weight gain in this group during this period. This cross-sectional study involved 3,462 participants recruited through the MicroEmbrain Inc. Online survey panel. Participation emails were sent by the research company to the online survey panel, and individuals who voluntarily agreed to participate responded to the survey. The participants consisted of residents aged 19 and above from Seoul, with sample distribution taking considering sex, age, and region. Height, and weight before and during the COVID-19 pandemic were self-reported. The analysis revealed that compared with that of pre-COVID-19 statistics, 11 % of all participants entered the overweight or obese categories post COVID-19, and among those who were overweight or obese before COVID-19, 42.5 % reported weight gain. Both groups had relatively younger individuals, higher stress levels, spent more time alone, and had increased usage of online platforms including online food purchasing. Post-COVID-19 wt gain among individuals with pre-existing overweight or obesity status was associated with a higher frequency of solitary drinking (odds ratio [OR] = 1.407, 95 % confidence interval [CI] = 1.024–1.932), increased online leisure time (OR = 1.336, 95 % CI = 1.063–1.678), and increased use of meal delivery services (OR = 1.307, 95 % CI = 1.026–1.664). The prevalence of obesity has continued to rise after COVID-19 pandemic, highlighting the need for interventions that mitigate the negative impact of the pandemic on health behavior.

Social media as a supporting mechanism during COVID-19 in Indonesia: A quantitative study on isolation among elders

BackgroundCOVID-19 pandemic has posed mental health challenges for people from all walks of life, including the elders in Indonesia. Due to the wide-ranging effects of this pandemic due to various phases of smart, partial, or full lockdown, people worldwide have faced serious problems particularly with their mental health. MethodsThis quantitative study analyses the experiences of the general public particularly focused on elders, those who are in isolation due to the COVID-19 protocols and limited social or physical interaction within the society. For investigating the social support mechanism among respondents, we have gathered a sample of respondents who are elders and using social media. The data reflect the opinion of respondents on elders during this pandemic. A survey was designed to gather data from elders facing mental health issues and using social media platforms to seek information in Indonesia. An online social support scale, self-awareness and insight scale were deployed to measure responses to the issue at hand. ResultsThe data show that the elders had varied conceptualisations about COVID-19 relating to the pandemic, i.e., eating habits, fear of death, strengthening religiosity in eating practices, fear of interacting with people, and interaction patterns. Elders were restricted to their places and had limited physical social interactions, thus social media platforms have played a significant role in developing online interaction among elders, to speak and discuss their matters for coping with the issues of isolation and mental health. ConclusionThe online media platform is considered a great support for elders to stay connected with families, friends, as well as with other communities. The study concludes that despite declaring the non-emergency status of COVID-19, elders have still suffered with long-term repercussions of this pandemic affecting their mental health.

The travel behaviors before and after lockdown: Case study on Shanghai, 2022

From April 1 to May 31, 2022, Shanghai implemented a full lockdown in response to the rapid spread of COVID-19 to protect the vulnerable population. This paper aims to comprehensively assess the impact of this lockdown. Traffic data for March and June of 2022 were collected, including the vehicular traffic volumes from four typical intersections and metro ridership. Other important indicators, including COVID-19 cases, Baidu Index and Shanghai Stock Exchange Index, were also employed. The results show that: (1) In both March and June, except for the intersection near the major hospital, the ratios between the weekday and weekend traffic volumes were higher than those observed before the pandemic, which implies a significant drop in leisure trips during these periods. (2) The evolution of traffic volume in March was largely driven by some important COVID-19-related events, while the traffic volume in June showed a more spontaneous and stepwise recovery pattern. (3) The confirmed cases had a significant impact on the traffic volume in March, but the time lag of the confirmed cases was not found. The impact of confirmed cases on traffic volume in June was not significant. (4) The transfer from public transport to private ones could be observed during this period, but the recovery proportion of Shanghai metro ridership is higher than most other cities examined in this study, suggesting the importance of enhancing public confidence for public transport in the post-pandemic period. These findings can aid in refining potential pandemic measures for future scenarios.

Impact of COVID-19 Lockdown on Inhaled Toxic Elements in PM2.5 in Beijing: Composition Characterization and Source-Specific Health Risks Assessment

In early 2020, China experienced a mass outbreak of a novel coronavirus disease (COVID-19). With an aim to evaluate the impact of emission variations on toxic element species in PM2.5 and the health risks associated with inhalation exposure during COVID-19, we collected PM2.5 filter samples in Beijing from January 1 to February 28, 2020. Positive matrix factorization (PMF) and a health risk (HR) assessment model were used to assess the health risks of the toxic elements and critical risk sources. The total concentration of eight toxic elements (Se, Cd, Pb, Zn, As, Cu, Ni, and Cr) in Beijing showed a trend of first increasing and then decreasing: full lockdown (322.9 ng m−3) > pre-lockdown (264.2 ng m−3) > partial lockdown (245.3 ng m−3). During the lockdown period, stringent control measures resulted in significant reductions (6−20%) in Zn, Pb, Cd, and Ni levels, while concentrations of Se, As, Cu, and Cr were unexpectedly elevated (14−348%). A total of five sources was identified: traffic emission, coal combustion, dust emission, industrial emission and mixed source of biomass burning and firework combustion. Total carcinogenic risk (TCR) of the selected toxic elements exceeded the US EPA limits for children and adults. As and Cr (IV) were the main contributors to non-carcinogenic and carcinogenic risks, respectively. For source-resolved risks, coal combustion was the main contributor to HI (43%), while industrial emissions were the main cause of TCR (45%). Additionally, increased contributions from coal combustion, biomass burning, and firework combustion during the full lockdown elevated the HI and TCR values.

Impact of COVID-19 lockdowns on NOx emissions: A sector-specific analysis of transportation and power generation

To limit the transmission of COVID-19, a series of rigorous lockdown measures were implemented worldwide. These measures have caused a massive impact on the socio-economic conditions, especially on traffic flow as well as the demand for electricity. This study designs an integrated approach that incorporating an atmospheric dispersion model into a state-of-the-art traffic flow and power consumptions models to simulate the dispersion of the resultant emissions of NOx, considering the changes during the full and partial lockdown periods in comparison to the corresponding pre-pandemic period. This study is geographically focused on Kuwait, examining the impact of COVID-19 lockdown measures on NOx emissions within its transportation and power generation sectors. The results show that hourly averaged electricity generating decreased by 5.6% and 4.5% as a result of the partial lockdown and full lockdown respectively. Crude oil consumption increased from 12% to 27% during the partial lockdown, and rose to represent 20% as a result of the full lockdown. This is because power plants had to act quickly to secure supply chains and manage fuel inventory. More natural gas was consumed as a result of the partial lockdown, raising its share of total energy consumption to 57%. This resulted in a decrease of 14% and 36% in NOx emissions. Hotspots for NOx concentrations were observed over densely populated residential areas during the full lockdown period, since transportation-related emissions accounted for the bulk of NOx emissions during the full lockdown. In contrast, maximum NOx concentration hotspot for the partial lockdown period was observed in the vicinity of power plants. This sector-specific analysis provides insights into sustaining air quality gains by targeting interventions for transportation and energy use.

Using Quality Control Charts for Monitoring COVID-19 Daily Cases and Deaths in Türkiye

The national partial curfews in Turkey, announced after normal time period in 2020’s summer, began on 18.11.2020. In this study, for the periods between 25.11.2020-31.05.2022, the daily new cases and for the periods between 27.03.2020-31.05.2022 deaths and fatality rates are monitored. In this research, Run charts, control charts of c and p are used for monitoring the COVID-19 process in Turkey. In the periods of national extended curfews (December 1, 2020–February 28, 2021), full lockdown (April 29–May 16, 2021) and gradual normalization (May 17– May 31, 2021) the number of daily cases and deaths show downward trend as it is expected. However, in the periods of local decision-making phase (March 1–29, 2021) and revised local decision-making phase (March 30–April 13, 2021) the number of new daily cases and deaths show upward trend. For the latest period between June 1, 2021-May 31, 2022, in winter season the number of deaths and daily cases increasing as it is expected then in spring season they decrease. The daily new cases and deaths due to COVID-19 monitored rapidly and effectively by control charts. It is obvious that some of the public did not internalize the negative impacts of the virus in 2020 and consequently disregarded health guidelines in 2021.

Drones Usage Opportunities For Entrepreneurs Contributing Towards Aatmanirbar Bharat

The year 2020 witnessed a significant turning point for the world economy with the discovery of a dreadfulvirus named ‘CORONA VIRUS’ originating from the world’s largest manufacturing hub – China, and stillthe world is fighting with it. Within a few days it covered almost all the nations across the globe. To put acheck on the speedy spread of the virus and break the chain, the GOI announced nationwide lockdown on24th March 2020.As a result all the manufacturing units, service sectors and other industries stopped theirproduction except medical related emergencies. The whole nation went into full lockdown. The financialhealth of the nation was badly affected by the virus. After about 2.5 months, country’s growth engine wasrestarted with unlock -01. The union government at that juncture gave a big push to the economy with 20lakh crores of rupees to help the nation to survive and become AatmaNirbhar / self-reliant. It is the newversion of “Make in India” campaign declared by Honourable Prime Minister Narendra Modi on25thSeptember 2014. The drone market reflects advanced technology. As a result, new opportunities for theusage of drones in numerous industries are arising. Therefore, as new possibilities arise, so do fresh dangersto people's lives and the safety of enterprises. Different organizations have already incorporated drones intotheir operations, providing a source to study and learn. As a result, authors has attempt to addressfundamental inquiries including the benefits that the usage of drones can offer to businesses, potential risks,practical restrictions, and entrepreneurial opportunities for drone industries.

Effectiveness of vaccination, travel load, and facemask use control strategies for controlling COVID Delta variant: the case of Sydney Metropolitan Area

AbstractThe Delta variant of SARS-CoV-2, specifically identified as B.1.617.2, is responsible for the severe outbreaks witnessed globally, including in various countries and cities, with Sydney Greater Metropolitan Area (Sydney GMA) being no exception. According to scientific studies, the Delta strain exhibits increased contagion and leads to a higher incidence of vaccine breakthrough cases, posing significant challenges to pandemic control efforts. In this study, we explore the efficacy of three fundamental control strategies—namely, vaccination rates, adherence to facemask usage, and the management of travel loads—in mitigating the spread of the disease and, consequently, eliminating the Delta variant pandemic in Sydney GMA. We employ an agent-based disease spread model to thoroughly investigate these strategies. Moreover, factorial MANOVA is utilised to assess the significance of variations in the impact of diverse compliance levels with the aforementioned control strategies on various attributes of the pandemic. As complete lockdowns and stringent travel regulations have the potential to induce physical and mental distress in individuals and economic crises for countries, our study examines the interactive effects of implementing control strategies to mitigate the necessity for a full lockdown. The simulation results suggest that suppressing a pandemic with similar characteristics to Delta variant of COVID is feasible with a vaccination rate of 80% or higher, as long as travel load and activity participation are maintained at pre-COVID levels. Alternatively, a more realistic and attainable combination of control measures—a vaccination rate of 60%, a facemask usage level of 60%, and a 50% compliance level for social distancing—demonstrates comparable efficacy, leading to effective pandemic control. Notably, the vaccination rate emerges as a more potent control strategy compared to others in the elimination of the disease within society.

COVID–19 Impacts: Government Interventions and Residential Housing Prices in Lagos Metropolis

The outbreak of the COVID-19 pandemic had profound impact on global economies. Various studies have focused on the impact of COVID-19 interventions on the financial market such as stocks markets, but few studies examined government interventions influence on housing market, particularly the housing price. This paper explores the influence of the government interventions during COVID-19 on housing prices in the residential areas of Lagos Metropolis in Nigeria. The aim is to understand whether price variations can be attributed to the epidemic shocks, by employing a review of literature on government interventions for COVID 19 pandemic and housing prices (2009 & 2015) before the pandemic and 2020 Lagos Property Market Consensus Report during the pandemic. Descriptive statistics were deployed in the application of difference-in-difference method for data analysis. The findings revealed that a lesser percentage of housing price increase was associated with the decrease in the number of COVID-19 cases and less partiallockdown measures. While a higher percentage housing price increase was associated with an increase in the number of COVID-19 cases along with more stringent full lockdown measures. The study concluded that housing price change was influenced by government interventions during COVID-19 pandemic in the Lagos Metropolis. The study recommends that to reduce the spread of COVID-19 infections in order to ensure a lesser percentage increase in housing price, spacious and more affordable housing units should be encouraged. Therefore, the effectiveness of lockdown and restriction measures should be further assessed, given their impacts on individual liberties and housing affordability.

The impact of the COVID-19 pandemic on the Galapagos Islands' seafood system from consumers’ perspectives

The COVID-19 pandemic's early stages severely impacted global fisheries, particularly areas heavily reliant on imported food and tourism like the Galapagos Islands, Ecuador. To contain the spread of the virus, a full lockdown was implemented. However, the collapse of the tourism industry precipitated the worst economic crisis in the history of this multiple-use marine protected area. This paper examines the impact of the pandemic's early stages on consumption patterns and seafood security in the Galapagos from consumers' perspective, drawing on online surveys conducted during the lockdown. Our findings revealed pre-existing seafood insecurity across the archipelago, further exacerbated by the pandemic on the least-populated island. Nevertheless, the seafood system displayed moderated resilience to the pandemic’s socioeconomic disruptions. A variety of adaptive responses were adopted by Galapagos residents to cope with the lockdown. Consumers modified their seafood consumption habits, while fishers adapted their harvesting and marketing strategies. Such adaptive responses were shaped by the unique socioeconomic characteristics of each inhabited island and the ability of seafood suppliers to shift from a tourism- and export-oriented to a resident- and domestic-oriented market. This transition has created novel opportunities to foster a systemic transformation of the Galapagos seafood system to enhance its resilience against future crises caused by new pandemics, climate change, or other natural and anthropogenic drivers of change.

Pneumococcal nasopharyngeal carriage in children and adults self-confined at home during a COVID-19 national lockdown.

Despite growing evidence of reduced invasive and non-invasive pneumococcal disease attributed to public health measures against the COVID-19 pandemic, the effect of these measures on pneumococcal carriage remains unclear. This study aimed to assess pneumococcal nasopharyngeal carriage among children and adults self-confined at home during the COVID-19 national lockdown in Spain while identifying predictors of pneumococcal carriage in children. Household study conducted across the metropolitan area of Barcelona (Spain) between April-June 2020. Nasopharyngeal samples were collected from young children and adults for real-time PCR pneumococcal lytA and wgz gene detection, quantification, and serotyping, as well as for detection of respiratory viruses. Among 332 children (median age: 3.1 years [IQR: 1.9-4.0 years]; 59% male) and 278 adults (median age: 38.9 years [IQR: 36.1-41.3 years]; 64% female), pneumococcal carriage rates were 28.3% and 2.5%, respectively. Highly invasive serotypes 3, 7F/7A, and 19A were detected in 14.0% of samples from children carriers. Pneumococcal co-infections with respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and influenza virus (IV) were not identified in children. Attendance to kindergarten before the lockdown (aOR: 2.65; IQR: 1.57-4.47; p<0.001) and household crowding (aOR: 1.85; IQR: 1.09-3.15; p = 0.02) were independent risk factors for children's pneumococcal carriage. Pneumococcal carriage rate among quarantined children during a full COVID-19 lockdown was moderate and correlated with limited presence of highly invasive serotypes and absence of pneumococcal co-infections with RSV, hMPV, and IV. Pre-lockdown daycare and household crowding predisposed children to carriage.

The Effect of Lockdown on the Number of Trauma Cases and the Pattern of Injury in a Trauma Centre in Dubai During the Month of Lockdown and Comparing it to the Pre-COVID Time

Background: Due to the COVID-19 pandemic, full time lockdown was applied in many countries around the world. Published literature shows that the risk of suicide and assaults has increased but the risk of motor vehicle accidents has reduced. In this research, we want to study the impact of lockdown during the COVID-19 pandemic on the trauma cases who presented to the trauma cen-ter. Method: This retrospective cross-sectional study retrieved all the trauma cases who presented to the Emergency department in Rashid hospital during April 2019 and April 2020 from the patients&amp;apos; electronic records system. We included all the trauma cases who fell in the Canadian Triage and Acuity Scale (CTAS) of T1-T3 only. Results: Total of 3,268 trauma cases were studied. The number of cases in April 2019 was double the cases in 2020. However, the pattern of injuries was variable in the two years. There were high-er rates of motor vehicle accidents in non-lockdown month than the lockdown month (10.5% and 6.5%, respectively) (p-value

Mental health impact on patients with COVID-19 in the community under a long period of full lockdown in Vietnam.

We aimed to investigate the impact on the mental health of patients with COVID-19 in a centralized isolation facility in the community who experienced a long period of full lockdown during the fourth wave of the COVID-19 pandemic in Vietnam. We performed a retrospective cross-sectional study among 125 patients with COVID-19 in a centralized isolation facility in the community of Ho Chi Minh City from September to November 2021. We collected data on depression, anxiety, and stress symptoms, as indicated by scores on the Depression Anxiety Stress Scale-21, as well as sociodemographic characteristics. The prevalence of depression, anxiety, and stress among patients with COVID-19 was 14.4%, 20.8%, and 20.0%, respectively. Depression scores were significantly and positively correlated with body mass index whereas stress scores were significantly and positively correlated with age. Our findings indicated an increased prevalence of depression, anxiety, and stress among patients with COVID-19 who were in a centralized isolation facility during the fourth COVID-19 wave in Vietnam. Overweight and older age were identified as risk factors for adverse mental health in patients with COVID-19. Psychological intervention programs should be implemented in isolation facilities for individuals with COVID-19 infection.

Entrepreneurial (re)orientation in the face of crisis: Is it worth modifying entrepreneurial strategy?

PURPOSE: This article aims to determine how companies in the SME sector modify their business strategies in response to changes in the external environment. The research focused on modifications to entrepreneurial strategies expressed through the fundamental dimensions of entrepreneurial orientation (EO): risk-taking, innovativeness, and proactiveness. Additionally, it identified which types of reactions (modifications in strategies) lead to the most favorable changes in firm performance. The external environment was determined based on the market situation that resulted from the emergence of the COVID-19 pandemic. METHODOLOGY: This is quantitative research. The study utilized data from 126 small printing businesses operating throughout Poland. Analyses were conducted on the data that reflected modifications in entrepreneurial behaviors and performance during three periods: the pre-crisis period, the initial phase of the crisis (the full lockdown period), and the second phase of the crisis (the period of easing the restrictions). The identification of the behavior types was carried out using cluster analysis. FINDINGS: The results of the research led to the conclusion that, with a change in market conditions, companies significantly change their levels of EO. In particular, the surveyed companies reduced their levels of EO during the outbreak of the COVID-19 pandemic. At the same time, this decrease was mainly due to significant decreases in risk-taking. The levels of EO increased when the conditions improved due to significant increases in innovativeness and proactiveness. Moreover, the analysis enabled the identification of four types of reactions to the emergence of the crisis as well as three types of reactions to the improvement of the external conditions that resulted from the easing of restrictions and the introduction of anti-crisis support measures for businesses. Additionally, it was demonstrated that the type of reaction had a significant impact on the changes in the performances of the examined companies. In particular, it was shown that the lowest decline in performance during the initial phase of crisis could be observed in passive enterprises, i.e., those that did not modify their entrepreneurial strategies (did not alter their levels of individual dimensions of EO). The greatest increase in performance was achieved during the period of easing restrictions by those companies that significantly enhanced their activities across all of the considered dimensions of EO. IMPLICATIONS: The research results provided insights for entrepreneurs in strategic management. Specifically, they learned about the modifications in entrepreneurial behaviors that could lead to the most favorable and optimal improvements in a firm’s performance when market conditions change. ORIGINALITY AND VALUE: The study contributes to the literature concerning reactions to changes in market conditions. This innovative approach considers dynamics where the changes themselves are variables. In particular, this research identifies types of entrepreneurial reactions to market condition changes in terms of dimensions of entrepreneurial orientation. Furthermore, it provides an answer to how firm performance evolved regarding various reaction types (using the example of the printing industry).

Exploring the Influence of Land Use on the Urban Carbonyl Sulfide Budget: A Case Study of the Metropolitan Area of Barcelona

AbstractCarbonyl sulfide (OCS) is used to quantify the carbon capture potential of the biosphere because of its direct correlation with CO2 uptake during photosynthesis. However, to constrain the urban biosphere signal, it is necessary to evaluate potential anthropogenic sources. We conducted two sampling campaigns in the Metropolitan Area of Barcelona (AMB), Spain, during May (full COVID lockdown) and October 2020 to measure the spatial distribution and variability of OCS in four urban land uses as follows: built, urban forest, urban park, and peri‐urban agriculture. The OCS background levels determined at Tibidabo (442 m asl) were approximately 484 ± 20 ppt and 407 ± 8 ppt for May and October 2020, respectively, and agreed with other seasonal surveys conducted in Europe during that same period. Averaged emissions were in the range of +Δ12 ± 40 ppt for the city and were +Δ9.4 ± 40.9 ppt for urban +Δ22.1 ± 48 ppt for urban green +Δ20.7 ± 42.9 ppt for agricultural and −Δ4.8 ± 19.6 ppt for forest. The urban values ranged from neutral to above background, suggesting nearby anthropogenic and marine emissions such as +Δ150 ppt in Montjuic, which is downwind of Barcelona's harbor. During the crop‐growing season in May, the agricultural areas consistently showed values below the background (up to −Δ76 ppt in Gavà, uptake) at 7:00 UTC when the land breezes were dominant, while later in the morning, when the sea breeze are developed, the plant sink is masked by the transport of marine emissions. Urban forests located north of Tibidabo showed OCS values up to −Δ70 ppt, suggesting significant uptake by urban forests. We conclude that determining the urban biosphere signal using OCS as a tracer is more complex than expected because the marine and anthropogenic emissions from the port strongly impact the spatial‐temporal distribution of OCS.
