| 5951 | Demand and price fluctuations effect on risk and profit of single and clustered microgrids during COVID-19 pandemic COVID-19's widespread distribution is wreaking havoc on people's lives all over the world. This pandemic has also had a significant impact on energy consumption. Its influence can be seen in the power system's operation and the market as well. The power consumers' habits and demand curves have been changed at a breakneck pace. In this work, a one-year mixed-integer programming (MIP) problem has been developed to compare the power consumption between 2019 and 2020 in the United States as an example regarding the COVID-19 pandemic effect in order to better prepare for possible similar future events. 100% renewable single microgrids (SMGs) are studied using wind turbines and photovoltaics. Batteries are also employed since it is inevitable when the system uses renewables. Additionally, it is possible for the SMGs to trade power with the main grid as needed. The effect of the SMGs’ clustering to form the multi-microgrids (MMGs) is also considered. In order to investigate the risk of the system during the COVID-19 and formation of MMG, downside risk constraints are applied to the proposed model. Furthermore, a stylized short-run consumers demand model is proposed, using elasticity and assessed responses regarding the average household consumption for households during on-peak and off-peak periods. The simulation results show that COVID-19 generally reduces the demand, increases the profit of the system, and decreases the economic risk of the power system’s operation. Moreover, SMGs clustering to organize MMG dramatically enhances the profit of the system as well as improves the risk level of the system. | N/A | 2022 | | CORD-19 |
| 5952 | Airborne infection risk assessment of COVID-19 in an inpatient department through on-site occupant behavior surveys Airborne transmission is a possible infection route of the coronavirus disease 2019 (COVID-19). This investigation focuses on the airborne infection risk of COVID-19 in a nursing unit in an inpatient building in Shenzhen, China. On-site measurements and questionnaire surveys were conducted to obtain the air change rates and occupant trajectories, respectively. The aerosol transport and dose–response models were applied to evaluate the infection risk. The average outdoor air change rate measured in the wards was 1.1 h−1, which is below the minimum limit of 2.0 h−1 required by ASHRAE 170–2021. Considering the surveyed occupant behavior during one week, the patients and their attendants spent an average of 19.4 h/d and 15.1 h/d, respectively, in the wards, whereas the nurses primarily worked in the nurse station (3.0 h/d) and wards (2.4 h/d). The doctors primarily worked in their offices (2.6 h/d) and wards (1.1 h/d). Assuming one undetected COVID-19 infector emitting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the nursing unit, we calculated the accumulated viral dose and infection probabilities of the occupants. After one week, the cumulative infection risks of the patients and attendants were almost equal (0.002), and were higher than those of the nurses (0.0013) and doctors (0.0004). Proper protection measures, such as reducing the number of attendants, increasing the air change rate, and wearing masks, were found to reduce the infection risk. It should be noted that the reported results are based on several assumptions, such as the speculated virological properties of SARS-CoV-2 and the particular trajectories of occupants. Moreover, only second generations of transmission were taken into consideration, whereas in reality, the week-long exposure may cause third generation of transmission or worse. | N/A | 2022 | | CORD-19 |
| 5953 | Guillain-Barre syndrome following COVID-19 vaccination: a case report and an updated review Background : Coronavirus disease-2019 (COVID-19) has caused a pandemic that has recently affected every aspect of life. Fortunately, many vaccines with high safety and efficacy profiles were developed timely to face this pandemic. In a very short time, billions of people were vaccinated. In the meantime, a wide range of neurological syndromes are being reported. Guillain-Barré syndrome (GBS) which is a rare immune-mediated post-infectious peripheral neuropathy was reported after both the COVID-19 infection itself and many types of its vaccines. Methods : We are reporting a case of post-AstraZeneca vaccine GBS and reviewing the literature of all reported post-COVID-19 vaccines GBS till July 2021. Results : 29 adult patients were reported. Of them 58.6% were males. Their mean age is 58.2 years. The median time to clinical onset after vaccine administration was 13.2 days. 86.2% of patients had their symptoms following immunization with the 1st dose of AstraZeneca vector-based covid vaccine. Facial palsy was the most predominant single symptom in 75.8% of patients. Conclusion : Guillain-Barré syndrome is a well-recognized but still rare adverse event following vaccination against COVID-19. Although preliminary data incriminates viral vector-based vaccines more than the other types, active post-vaccination surveillance and more powerful statistics are mandatory to reach a solid conclusion regarding the presence of a causal relation. | N/A | 2022 | | CORD-19 |
| 5954 | Evaluating the accessibility benefits of the new BRT system during the COVID-19 pandemic in Winnipeg, Canada Recently, in Winnipeg, the implementation of new bus rapid transit (BRT) system in the middle of the COVID-19 pandemic has raised many concerns, challenging the rationale behind the untimely release. However, the new BRT service can benefit low-income, socio-economically vulnerable, and transit captive passengers who must travel to essential services and work opportunities during the pandemic. This study evaluates whether the new BRT system has positive impacts on accessibility to such essential services during the pandemic. Isochrones with different time budgets as well as times of a day are generated based on high-resolution public transit network via the General Transit Feed Specification (GTFS) data and used for evaluating accessibility benefits before and after the BRT construction. The new BRT service in Winnipeg demonstrates varying accessibility impacts across different parts of the BRT corridor. Areas near dedicated lane-section show a significant increase, whereas areas near non-dedicated lane sections show a decrease in accessibility. Nevertheless, across the whole BRT corridor, the new BRT service presents an overall increase in accessibility to essential services. This demonstrates the positive accessibility benefits of the new BRT service to residents seeking essential services during the COVID-19 pandemic. A decrease in accessibility along some parts suggests the necessity of using local transit improvement strategies (e.g., dedicated lanes) to improve service speed when planning BRT services within urban areas. | N/A | 2022 | | CORD-19 |

| 5957 | Policing the coronavirus pandemic: Nigeria police senior officers' views on preparedness, response, legitimacy and post-COVID policing In the wake of pandemic policing occasioned by COVID-19, Nigeria police have been facing challenges of a lack of legitimacy, together with what is termed the militarization of police operations. This has impacted considerably on police–community relations. Meanwhile, early reports on the police response to the pandemic indicated high levels of lockdown violation, despite adoption of a militarized option in the enforcement of restriction orders. In reviewing one of the first police interventions on a public health crisis in Nigeria, a qualitative study was conducted among top-ranking police officers who supervised the enforcement of lockdown and other COVID-19 measures. Sixteen interviews were conducted and a thematic analysis of the narratives was carried out. Police unpreparedness for public health interventions, and public resistance to the use of repressive, force-led styles of policing were identified as major impediments to positive pandemic policing. Therefore, police officers are advised to ensure the application of procedurally just practices in their interactions with the public. | N/A | 2022 | | CORD-19 |
| 5958 | COVID-19 and crises of higher education: Responses and intensifying inequalities in the Global South This special issue contributes to the vibrant debates concerning the ‘responses and intensifying inequalities in the Global South’ underway with regard to COVID-19 and the subsequent crises of higher education. With neoliberal globalization in a deeper crisis by the pandemic, transforming higher education and teaching configurations in ways that appease the rich and powerful players, while simultaneously seeking to neutralize forms of equity in education. Rather than pointing fingers at the broken structures and wider external economic framework, we argue that re-centring the humanistic, holistic and bottom-up approach that frames the post-pandemic higher education offers a more useful framework for understanding educational transformation in the contemporary period. | N/A | 2021 | | CORD-19 |
| 5959 | Couple Connectedness in the Time of COVID-19 The COVID-19 pandemic has resulted in unprecedented global morbidity and mortality which altered people's daily lives, as well as created multiple societal challenges. One significant problem posed by this unique stressor is maintaining healthy intimate relationships, which are linked to mental and physical health. The literature has shown that the pandemic has exacerbated issues for couples such as financial difficulties, a lack of privacy, medical issues, and family and professional concerns. The pandemic has also forced all healthcare systems, hospitals, and clinics to quickly incorporate telehealth services. The number of requests for mental health consultations has risen to the point where demand exceeds supply. This paper provides an overview of ways couples can stay emotionally connected during this time as well as provide future directions for therapists to help couples develop or improve adaptive relationship mechanisms. | Fam J Alex Va | 2022 | | CORD-19 |
| 5960 | Is paying bribes worthwhile? Corruption and innovation in middle-income countries Corruption research in economics has a long history. Seminal early articles, and older findings contrast with newer developments which have as yet not been measured empirically; in particular the link between corruption and innovating activities suffers from multiple results, on both a national country and company or firm level. This paper examines the corruption-innovation link in transition and emerging countries as the decision to corrupt, and the ability to innovate may not be independent. An endogenous switching regression model is advocated as a suitably methodological way of modeling the joint determination of a firm’s innovation and possible bribes as it implies not only a selection between corrupted and non-corrupted firms, but also heterogeneous effects on innovative activities. The paper shows that, when the selection effect is adequately considered, different firms’ strategies arise. In particular, the treatment effect of corruption on innovation is positive for corrupting firms and negative for non-corrupting firms. Corrupting firms appear rational because paying bribes increases their innovative activities. However, non-corrupting firms also appear rational because in the presence of bribes, their innovating activities would be fewer. Thus, when the selection effect is adequately considered, the effects of so-called “greasing-and-sanding-the-wheels” can co-exist. Finally, the role of competition is also considered. Building on these results, future research can move forward to re-examine economic outcomes such as the productivity or the economic impact of corruption, in the presence (or absence) of selection processes. | N/A | 2022 | | CORD-19 |

| 5972 | A novel architecture of Web-GIS for mapping and analysis of echinococcosis in Poland Echinococcosis is an infectious disease transferred through ingestion of food or water which has been contaminated with eggs of the Echinococcus tapeworm, which are spread by intermediate parasite hosts. Because the latter are primarily territorial, research related to diagnosis and prevention of echinococcosis requires investigation of environmental factors, which can be supported with the use of a Geographical Information System (GIS). In particular, since this type of research is usually performed by a team of medical researchers working individually with many patients, it can greatly benefit from the use of a Web-GIS, which provides remote access to data integration, storage and analysis tools. However, most existing Web-GIS solutions dedicated for disease mapping either exhibit limited functionality and interactivity (often due to the use of a thin-client approach) or are tied to a particular technological platform through a thick client based on a browser plugin. Moreover, few of the existing solutions provide user-friendly tools for data input, and none is directly integrated into the workflow of clinicians. This paper proposes a novel system architecture for Web-GIS dedicated to disease mapping, which attempts to optimize the use of client and server hardware resources while providing the user with a variety of analytic functionalities. The proposed architecture has been implemented in the form of a system for remote mapping and analysis of echinococcosis cases in Poland, which has been designed in cooperation with a major Polish hospital centre. | N/A | 2022 | | CORD-19 |
| 5973 | Role of social media tools in online teaching: perception of physiotherapy students and knowledge translation BACKGROUND: During the COVID-19 lockdown period many education institutions have shifted their focus from the traditional face-to-face education to online instruction mainly through various social media (SM) tools. However, it is not known if these results can be generalized across locations where infrastructure facilities are unevenly distributed. Further, no previous work has explored the role played by SM tools in knowledge translation. The objectives of this work are 1. To evaluate the students perceptions on the accessibility and acceptability of SM tools via an anonymous online survey and 2. Assess the efficacy of SM tools as an educational medium in imparting knowledge change. An online survey using an anonymous web-based questionnaire was conducted to assess the student’s accessibility and acceptability of SM tools as a direct information sharing pathway between the faculty and students. A randomized comparative design was utilized to evaluate knowledge change via an online examination administered 10 min before and after an online class delivered via 2 different SM platforms (Google meet, YouTube) and e-mail. RESULTS: Data were obtained from 627 participants through a survey. Though 71.1% of the respondents believed online classes have helped them in their study, only 21.4% and 22.6% of the participants strongly agreed that social networking platforms are helpful for teaching and will be used for teaching/learning in the future respectively. The ANOVA responses to evaluate knowledge transfer from 224 participants who were randomized to receive course content through Google meet, YouTube, and e-mail showed no significant differences in outcomes before and after the delivery of contents. CONCLUSION: Our findings suggest that multiple external and internal factors need to be addressed before substituting classroom teaching with online teaching, especially during emergencies. | N/A | 2022 | | CORD-19 |
| 5974 | Psychosocial and clinical impact of COVID-19 pandemic and its relationship to the quality of life in patients with rheumatoid arthritis: a cross-sectional study, Egypt BACKGROUND: Data have been pouring on the impact of the COVID-19 pandemic on patients with chronic diseases. This study aimed to address the relationship between the perceived fears of COVID-19 virus (FCV), psychological status, and quality of life (QoL) among patients with rheumatoid arthritis (RA) during the pandemic. This study included 100 patients with RA and an equal number of control subjects, who were recruited from Zagazig University rheumatology outpatient clinics, Egypt. All subjects were interviewed using the fear of COVID-19 scale (FCV-19S), Symptom Checklist-90 scale (SCL-90), and World Health Organization Quality of Life Scale (WHOQOL-BREF). Patients were additionally assessed using the Disease Activity Score 28 (DAS28) and Modified Health Assessment Questionnaire (MHAQ). RESULTS: There were significant differences between both groups in all QoL domains and most psychological dimensions. Most patients with RA experienced moderate-to-high disease activity and mild-to-moderate functional impairment (85% and 80%, respectively). FCV was correlated with the number of family members (P-value 0.020), and obsessive-compulsive (P-value 0.006), interpersonal sensitivity (P-value 0.035), hostility (P-value 0.017), phobia (P-value 0.010), and psychoticism (P-value 0.034) symptoms. Moderate-to-high disease activity was associated with reduced psychological QoL. Patients with moderate-to-severe functional impairment had worse QoL in all domains (except social). Prolonged illness duration was associated with worse social QoL. CONCLUSIONS: QoL was adversely affected in patients with RA during the pandemic. There was a robust relationship between FCV and the emergence of psychological symptoms. RA-related clinical factors like illness duration, disease activity, and functional disability were associated with reduced QoL in those patients. | N/A | 2022 | | CORD-19 |
| 5975 | Evolution of the emotional impact in patients with early inflammatory bowel disease during and after Covid-19 lockdown Background Patients with inflammatory bowel disease (IBD) are vulnerable to some psychological disorders. Here we describe the psychological impact of a COVID-19 pandemic lockdown in patients with IBD. Methods This multicenter prospective cohort study included 145 patients recently diagnosed with IBD. Data on clinical and demographic characteristics, anxiety and depression scales, and IBD activity were collected in two telephone surveys, during and after the first COVID-19 lockdown in Spain. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Results During lockdown, 33.1% and 24.1% scored high on the anxiety and depression scales, respectively. Independent factors related to anxiety (all values ORs; 95% CIs) during lockdown were female sex (2; 1.2–5.4) and IBD activity (4.3; 1.8–10.4). Factors related to depression were comorbidity (3.3; 1.1–9.8), IBD activity (6; 1.9–18.1), use of biologics (2.9; 1.1–7.6), and living alone or with one person (3.1; 1.2–8.2). After lockdown, anxiety and depression symptoms showed significant improvement, with 24.8% and 15.2% having high scores for anxiety and depression, respectively. Factors related to post-lockdown anxiety were female sex (2.5; 1.01–6.3), Crohn's disease (3.3; 1.3–8.5), and active IBD (4.1; 1.2–13.7). Factors associated with depression were previous history of mood and/or anxiety disorders (6.3; 1.6–24.9), active IBD (7.5; 2.1–26.8), and steroid use (6.4; 1.4–29). Conclusions Lockdown during the COVID-19 pandemic had a significant psychological impact in patients with IBD. Disease activity was related to the presence of anxiety and depression symptoms during and after lockdown. | N/A | 2022 | | CORD-19 |
| 5976 | Impact of the lockdown period due to the COVID-19 pandemic in patients with inflammatory bowel disease Introduction The lockdown period due to the coronavirus disease 2019 (COVID-19) in Spain probably had a significant emotional impact on chronic patients and hence on those who are suffering from inflammatory bowel disease (IBD) due to their high risk of emotional disorders. The aim of this study was to learn how COVID-19 influenced patients suffering from IBD during the quarantine period, focusing in particular on psychological distress through the Perceived Stress Scale-10 (PSS-10) and also the impact of the pandemic on therapeutic adherence using the Visual Analogue Scale (VAS). Patients and methods A prospective, single-centre and analytical observational study was carried out in the IBD unit in August 2020. Patients were contacted and interviewed by phone. A descriptive analysis was carried out and subsequently the factors associated with the loss of therapeutic adherence and higher-moderate levels of stress were analyzed through logistic regression multivariate analyses. Results A total of 426 patients were included with a median PSS-10 score of 12 (10–16). A higher level of stress was reported by those who were not married, women and those who experienced an increase in IBD-related symptoms. Adherence to treatment was not associated with stress based on the PSS-10 questionnaire. Conclusions Although the lockdown period due to the COVID-19 pandemic has probably had a significant emotional impact on Spaniards with IBD, IBD patients in general had lower PSS-10 scores. | N/A | 2022 | | CORD-19 |

| 5983 | Investigating the effects of regional characteristics on the spatial distribution of COVID-19 pandemic: a case of Turkey Today, the COVID-19 pandemic continues to threaten all humanity worldwide. Turkey, one of the countries severely affected by the disease, has 81 provinces showing regionally different incidence rate patterns. This study explores the effect of social, economic, demographic, climatic, and geographic characteristics of different regions on the COVID-19 spread in Turkey. Geographic Information System (GIS)-based spatial interpolation techniques and multiple linear regression analysis have been conducted to examine the relationship between provincial incidence rates and eighteen explanatory variables determined by an in-depth literature survey. Results show that five of eighteen predictors have a statistically significant impact and can explain 57% of the regional variability of the COVID-19 incidence rates. Urbanization level, education index, and wind speed positively associate with the virus spread, but the sunshine duration and average temperature negatively correlate. On the other hand, 43% of the variation is due to other factors not included in this study. Therefore, an interdisciplinary study should be carried out by participating in all the related fields such as natural sciences, engineering and technology, medical and health sciences, social sciences, and humanities to understand the dynamics of the disease. | N/A | 2022 | | CORD-19 |
| 5984 | Zeit-bezogene Perspektiven auf Jugend und Erfahrungen von Jugendlichen in der Corona-Pandemie This paper in the journal Gruppe. Interaktion. Organisation. (GIO) addresses the experiences of young people in Germany during the corona pandemic from a time-related perspective. For this, it draws on conceptualisations of time through which biographies can be understood as socially ordered structural patterns. First, theoretical reflections on youth are presented, focusing on psychological, educational and sociological perspectives with regards to characteristics that mark youth as a time of specific biographical changes. This is centred on somatic changes, the growing importance of peer relations and group experiences, as well as the implications of youth as a socially pre-structured time for education. These considerations provide the framework for the second part of the article. Results from the “JuCo” studies, undertaken by the research group “childhood—youth—family during times of COVID-19” at the Universities of Hildesheim and Frankfurt a. M., are presented. The data used are comments that respondents made at the end of an online questionnaire. The quotations indicate experiences of frustration about missed opportunities, increased performance pressure, and fears about the future among young people. Implications of these observations are discussed against the backdrop of needs and requirements for the time after the pandemic. The article closes with a summary, outlining the demand for creating open social spaces that foster opportunities for intergenerational and peer-related encounters among young people. | N/A | 2022 | | CORD-19 |
| 5985 | Modeling of factors affecting investment behavior during the pandemic: a grey-DEMATEL approach The study intends to examine the cause-and-effect relationship between Covid-19 and the factors affecting investment behavior in a South Asian economy. The investment behavior is considered as an MCDM problem. To address this problem, the study employs MCDM approach i.e., a blend of both DEMATEL and Grey theory due to its potential to deal with subjective judgments of investors. The results indicate that Covid-19 is the leading cause behind financial stress, psychophysiological health outcomes, investors' perception about the market, and investors' strategy. Among sub-factors, portfolio allocation is the most influenced sub-factor. Alteration in portfolio is a major challenge for emerging countries which have become attractive destinations for global investors. Overall, the significant contribution of the paper is to establish the interlinkages among the factors affecting investment behavior, given the uncertainty triggered by the pandemic. Although the literature provides evidence on this problem during normal situations, analysis of investment behavior during severe crisis is still lacking. The research will be immensely useful to different stakeholders such as government, policymakers, financial advisors, and investors in making their strategic or operational decisions. | N/A | 2022 | | CORD-19 |
| 5986 | Measurement instruments for fast and frequent data collection during the early phase of COVID-19 in Germany: reflections on the Mannheim Corona Study The outbreak of the COVID-19 pandemic has led to a vast increase in the demand for fast, frequent, and multi-faceted data to study the impact of the pandemic on people’s lives. Existing data collection infrastructures had to be adapted quickly during the early phase of the pandemic to meet this data demand. Our research group contributed to this by conducting the Mannheim Corona Study (MCS), a longitudinal probability-based online survey, in a daily rotating panel design that took place from March 20 through July 10, 2020. The fast-and-frequent panel data collection design of the MCS had numerous consequences for designing its questionnaires and choosing its measurement instruments. This included designing new instruments on the fly in the ever-changing pandemic environment, making efficient use of limited questionnaire space, and deciding on measurement frequencies in a structured manner under uncertain external conditions. In this report, we document the MCS approach to choosing measurement instruments fit for the purpose of fast and frequent data collection during the early phase of COVID-19 in Germany. We particularly highlight three examples of measurement instruments in the MCS and reflect on their measurement properties.

| 5987 | Is COVID-19 anticipating the future? Evidence from investors' sustainable orientation In this paper, we discuss the attractiveness of green and sustainable assets, from an investor perspective. Inspired by the current state of the art, with researchers positively (re)considering the added value of stocks associated with the fulfilment of sustainable development goals, we analyze whether such stocks demonstrated: (1) a different and (2) an outperforming dynamic during various stages of the COVID-19 pandemic. In particular, we examine sustainable-indexed assets and companies with a fully bio-based production system, against a counterfactual group of non-indexed activities operating in the same sectors. Asset connectivity is investigated by means of a correlation network, and portfolio optimization is applied to measure profitability. The results show: (1) fewer connections between bio-based assets and the “rest of the world,” suggesting that, given their potential long-term resilience, investors might consider them capable of mitigating COVID-19 systemic risk, and therefore a valid investment to hold; and (2) the effectiveness and profitability of bio-based assets in portfolios. Considering the latter finding, we document a switching effect after the hard lockdown phase, during which rational investors (seeking an optimal mean–variance) may have inferred the efficacy of capital re-allocation from simply sustainable assets to bio-based companies. Here, we discuss the potential role of the pandemic as an accelerator of the sustainable green transition, considering the welfare implications in terms of socio-economic wellbeing and reduction of negative environmental externalities deriving from the conversion of the traditional production and management system. The profitability of the returns investments might increase the attractiveness of sustainable management organizations, causing the diffusion of these virtuous systems to increase further. | N/A | 2022 | | CORD-19 |
| 5988 | Airline OR Innovations Soar During COVID-19 Recovery The Airline Group of the International Federation of Operational Research Societies (AGIFORS) held four conferences during May to July 2021 that focused on how COVID-19 was impacting and reshaping the airline industry. Dozens of airline representatives from around the world spoke about how fundamental changes in passenger demand and booking patterns are reshaping the airline industry and driving innovation and research needs. Customers are booking much closer to departure and are canceling or exchanging their tickets more frequently than before COVID-19. Volatility in demand has increased as travel restrictions change and borders reopen. Consequently, greater uncertainty in demand forecasts used as inputs to optimization algorithms is motivating the need for new approaches. Revenue management and scheduling departments are innovating how they predict market sizes and exploring ways to use new data sources or historic bookings in forecasting models. Scheduling and operations departments are making many more flight-cancellation and equipment-swap decisions one to three days from flight departure, which is changing the role of recovery planning. New urgency exists within crew to design duties and rosters that are robust to ever-evolving schedules. Across functional areas, the increasing emphasis is to develop integrated solutions that jointly optimize schedules, crew pairings, and crew rosters for demand forecasts that are uncertain at the time rosters are published. This paper describes how these changes are reshaping the airline industry during COVID-19, explains why short lead times for bookings and uncertainty in demand volumes are expected to remain after COVID-19, and describes how the airline industry is innovating and developing new operations research approaches for handling uncertain and volatile demand. | N/A | 2022 | | CORD-19 |
| 5989 | COVID-19 and the expanding role of international urban search and rescue (USAR) teams: the case of the 2020 Beirut explosions The paper conducts a case study on the international urban search and rescue (USAR) response to the Beirut explosions in August 2020. The incident is worth analysing because it was the first of the international USAR deployments under global travel restrictions arising from the COVID-19 pandemic. It will closely look at the activity of @fire Germany, which is self-recognised as a light USAR team, deployed to Beirut. Due to the arrangements imposed for COVID-19 prevention, it becomes more difficult for international USAR teams to arrive in affected areas quickly, meaning that the possibility for life-saving further decreases. Thus, international USAR teams must be flexible to contribute to early recovery activity after the completion of the search and rescue phase. The @fire Germany’s response gives a good example of how light international USAR teams could contribute to early recovery. Also, some countries might not want to receive or send international USAR teams due to the COVID-19 pandemic. In the COVID-19 era, strengthening national and local teams, or first responders, who are already in-country becomes critical to saving more lives. | N/A | 2022 | | CORD-19 |
| 5990 | Foreign investment in times of COVID-19: How strong is the flight to advanced economies? This paper investigates the extent of the flight to advanced economies by foreign investors at the onset of the COVID pandemic. Amid an overall decline of international positions, countries featuring higher GDP per capita, and belonging to the groups of advanced, G7, or Euro-area countries, appear to have been significantly less severely hit by the pandemic than developing countries. In particular, on comparing the growth rates of foreign liabilities at the end of the first quarter of 2020, the wedge between advanced and emerging countries is about 3%, and it is at least twice as large for G7 countries. This wedge is especially significant in the first quarter, and it is paired with the evidence of momentum trading by foreign investors. Our results are robust to the inclusion, as controls, of government stringency measures, alternative indicators of pandemic severity, sample specification and regression methods. | N/A | 2022 | | CORD-19 |
| 5991 | Online chemical engineering education during COVID-19 pandemic: Lessons learned from Pakistan The development of Covid-19 epidemic into a pandemic led to great changes in education delivery modes around the globe. Online education (OE) began after the closure of education buildings. The unprepared start of OE led to access barriers, challenges, and opportunities for improvement. This work explores the scope of OE during COVID-19 in Pakistani institutions offering the degree of Chemical Engineering. A mixed-method approach was followed with a sample of 10 teachers and 1200 students from public and private sector universities. Teacher data came from semi-structured interviews by email, while students’ views of their learning experiences were collected through an online survey. The learners' responses showed that the unprecedented and unprepared shift to online course delivery lowered their motivation and interest in learning and they do not perceive the present practice as useful for several reasons. However, the teachers believed that the transition to OE helped the continuity of education, though they had to face technical, personal, social, learning-management-related, and other barriers they were not adequately equipped to deal with effectively. The results imply the need for a rapid preparation phase to enhance the effectiveness of OE during a crisis. The results may assist academics and policymakers in revising decisions regarding the great education migration to OE. | N/A | 2022 | | CORD-19 |
| 5992 | A safe haven of SARS-CoV-2 in the environment: Prevalence and potential transmission risks in the effluent, sludge and biosolids The novel coronavirus, SARS-CoV-2, which has caused millions of death globally is recognized to be unstable and recalcitrant in the environment, especially in the way it has been evolving to form new and highly transmissible variants. Of particular concerns are human-environment interactions and the handling and reusing the environmental materials, such as effluents, sludge, or biosolids laden with the SARS-CoV-2 without adequate treatments, thereby suggesting potential transmission and health risks. This study assesses the prevalence of SARS-CoV-2 RNA in effluents, sludge, and biosolids. Further, we evaluate the environmental, ecological, and health risks of reusing these environmental materials by wastewater/sludge workers and farmers. A systematic review of literature from the Scopus database resulted in a total of 21 articles (11 for effluents, 8 for sludge, and 2 for biosolids) that met the criteria for meta-analysis, which are then subdivided into 30 meta-analyzed studies. The prevalence of SAR-CoV-2 RNA in effluent and sludge based on random-effect models are 27.51 and 1012.25, respectively, with a 95% CI between 6.14 and 48.89 for the effluent, and 104.78 and 1019.71 for the sludge. However, the prevalence of SARS-CoV-2 RNA in the biosolids based on the fixed-effect model is 30.59, with a 95% CI between 10.10 and 51.08. The prevalence of SARS-CoV-2 RNA in environmental materials indicates the inefficiency in some of the treatment systems currently deployed to inactivate and remove the novel virus, which could be a potential health risk concern to vulnerable wastewater workers in particular, and the environmental and ecological issues for the population at large. This timely review portends the associated risks in handling and reusing environmental materials without proper and adequate treatments. | N/A | 2022 | | CORD-19 |
| 5993 | The family and the state: a public choice perspective The family is an institution within which exchange takes place. The state depends on the productivity of families for its current and future revenues. Yet, work on family policy often ignores the role of local knowledge, incentives, and special interests, while families themselves are often overlooked in accounts of the unintended consequences of public policy. The work of Julian Simon is a notable exception. Building upon his insights about the family’s production of children in particular, this paper offers a way to think about family policy that is consistent with both family economics and public choice. I conclude by applying some basic principles to better understand three patterns: the gap between intended and actual fertility in the developing world today, the lack of successful pro-natal public policy, and the oscillation of totalitarian family policy. | N/A | 2022 | | CORD-19 |

| 5999 | Does flattening the curve make a difference? An investigation of the COVID-19 pandemic based on an SIR model We use a susceptible-infective-removed (SIR) model to examine the impacts of different isolation measures to combat the COVID-19 pandemic. The model predicts that strong isolation measures in the early stage of the pandemic can not only delay the time for the number of infections and deaths to reach the peak but also greatly reduce the cumulative number of infections and deaths. We verify the model predictions by using the simulation and the data of the COVID-19 cases. The results are independent of the joint distribution of the fatality rate and the initial number of active cases. | N/A | 2022 | | CORD-19 |
| 6000 | Neurological symptoms associated with SARS-CoV-2 infection in a tertiary hospital in Bogota, Colombia Introduction: SARS-CoV-2 infection is an emerging disease that represents a threat to life globally, with more than 179 million confirmed cases and 3 million deaths. In Colombia, where almost 5 million infections and approximately 127 thousand deaths have been reported, it presents a wide variety of neurological manifestations that range from mild to severe symptoms. Objective: This study describes the characteristics of neurological manifestations in patients with COVID-19 in the period March-September 2020 at a tertiary hospital in Bogota. Methods: We performed a cross-sectional descriptive study. We selected patients by non-probability sampling, including all patients attended by the neurology service at our hospital. We included all patients with infection confirmed by RT-PCR test and neurological disease confirmed by tomography, study of cerebrospinal fluid, and clinical manifestations reported in the medical history. We excluded epileptic patients who presented seizures as the only clinical manifestation. Results: In a total of 58 patients, the mean age was 58 years, with 60.3% of patients being men; 65.5% were alert at admission. The main neurological symptom was brain ischaemia, in 36.2%, followed by seizures, in 25.9%. Arterial hypertension was observed in 58.6%. We observed no alterations in the cerebrospinal fluid; the mean hospital stay was 35 days, and 41.4% of patients died. Conclusions: SARS-CoV-2 infection not only affects the respiratory system, but can also cause a range of neurological manifestations ranging from mild symptoms such as headache, dysgeusia, and anosmia to severe complications such as seizures, brain ischaemia/haemorrhage, encephalopathy, or death. | N/A | 2022 | | CORD-19 |
