| 2004 | The COVID-19, power generation and economy-Case study of a developing country The global COVID-19 pandemic created profound impact on every nation’s economy, education, healthcare, social and cultural life, domestic and international mobility at an unprecedented level. Since the start of the COVID-19 pandemic in early 2020, most nations are undergoing through frequent full or partial lockdowns, resulting in significant economic losses, and unprecedented suffering of hundreds of millions of people worldwide. Given the crucial role of electric power in economic activities, the purpose of this study is to investigate the impact of COVID-19 pandemic on power sector and economy in a developing/ emerging country as a case study. The study examined electric power generation and consumption, GDP growth, export, import, remittances, and various government measures undertaken during the COVID-19 pandemic in Bangladesh. Autoregressive distributed lag (ARDL) model was used to investigate correlation between COVID-19 cases and power consumption during full and partial lockdowns. The research revealed a long-run negative relationship between COVID-19 cases and power consumption during partial lockdowns. The study also revealed that the targeted and partial lockdowns accompanied by nation-wide mass vaccination program can steer the economy along the power sector with minimal or no impact during the COVID-19 pandemic. | N/A | 2022 | | CORD-19 |
| 2005 | Quantum computing led innovation for achieving a more sustainable Covid-19 healthcare industry Involvement of multiple stakeholders in healthcare industry, even the simple healthcare problems become complex due to classical approach to treatment. In the Covid-19 era where quick and accurate solutions in healthcare are needed along with quick collaboration of stakeholders such as patients, insurance agents, healthcare providers and medicine supplier etc., a classical computing approach is not enough. Therefore, this study aims to identify the role of quantum computing in disrupting the healthcare sector with the lens of organizational information processing theory (OIPT), creating a more sustainable (less strained) healthcare system. A semi-structured interview approach is adopted to gauge the expectations of professionals from healthcare industry regarding quantum computing. A structured approach of coding, using open, axial and selective approach is adopted to map the themes under quantum computing for healthcare industry. The findings indicate the potential applications of quantum computing for pharmaceutical, hospital, health insurance organizations along with patients to have precise and quick solutions to the problems, where greater accuracy and speed can be achieved. Existing research focuses on the technological background of quantum computing, whereas this study makes an effort to mark the beginning of quantum computing research with respect to organizational management theory. | N/A | 2022 | | CORD-19 |
| 2006 | Investor's herding behavior in Asian equity markets during COVID-19 period In this paper we investigate herding behavior triggered by the COVID-19 outbreak in 2020 by considering six typical Asian stock markets. Cross-sectional Standard Deviation (CSSD) and Cross-sectional Absolute Deviation (CSAD) have been employed as the key indicators, which are aligned with the Markov-switching regression and HS model to identify the presence and magnitude of herding. We then elaborate our study by examining herding in specific time slots and markets with different idiosyncratic volatility. Our empirical results show a clear presence of herding in the “Feb 2020-Jan 2021” time window and we have captured a sharp rise of the magnitude of herding during the market crash in March 2020, and found herding emerged in these markets with shocks and fierce fluctuations. | N/A | 2022 | | CORD-19 |

| 2008 | Treating Adolescent Anxiety and Depression in Primary Care Considering Pandemic Mental Health Fallout Child health experts have been studying pediatric mental illness for decades. Research quantifying high rates of pediatric mental illness along with a shortage of specialty providers demonstrated a need for change. Pediatric advocacy organizations encouraged pediatric primary care providers to offer a basic level of treatment for mild to moderate mental health symptoms in the primary care setting to help offset the pediatric mental health provider shortage and allow specialists to focus on patients with more severe symptoms. Fallout from the COVID-19 pandemic increased rates of pediatric mental illness, especially adolescent depression and anxiety. The time has come for pediatric primary care providers to embrace mental wellness in their practices, implement research-based interventions, break down barriers to treatment, and do their part to fight the National Children’s Mental Health Emergency ignited by the COVID-19 pandemic. | N/A | 2022 | | CORD-19 |

| 2010 | Successful Treatment of COVID-19 Patient on ECMO Using Mesenchymal Stromal Cells (MSC)-Derived Exosomes: A Case Report Introduction The use of mesenchymal stromal cells (MSC) was recently proposed as a promising intervention for COVID-19 related respiratory failure (RF). Prior studies have suggested that its larger size might lead to entrapment in extracorporeal membrane oxygenation (ECMO), affect circuit function, and attenuate its efficacy. We present a successful case of a severe COVID-19 patient treated with MSC-derived exosomes while receiving veno-venous (VV) ECMO support. Case Report 41-year-old unvaccinated obese White male with no past medical history presenting with shortness of breath and a +COVID-19 nasopharyngeal test was admitted receiving high-flow nasal cannula (HFNC), remdesivir, and dexamethasone (Day 1), followed by intubation (day 5), and a peripheral VV ECMO insertion (day 10) due to worsening RF. We used bivalirudin for post-ECMO anticoagulation. Subsequently, he received the first cycle of MSC-derived exosomes on alternative days (day 1, 3, & 5) between days 13-17, followed by the second cycle between days 34-38. After administration of exosomes, the plasma concentration of inflammatory markers reduced, including a decrease of 77% for ferritin, 74% for CRP, and 62% for procalcitonin in approximately one week, along with consistent improvement of PaO2/FiO2 ratio. ECMO membrane oxygenator was exchanged on day 23 at the time of tracheostomy. After successful weaning, ECMO decannulation was performed on day 47, and the patient was discharged home on day 61. Summary ECMO has emerged as a supportive strategy for patients with severe COVID-19 related RF. The patient's inflammatory response has been implicated in the pathophysiology of lung failure. Multiple pharmacological methods are employed to control the severity of this inflammatory response, thus preventing progression to the fibrotic stage of the disease. In our experience, MSC-derived exosomes neither resulted in any side effects nor impaired the function of ECMO and might have enhanced the recovery of the patient. | J Heart Lung Transplant | 2022 | | CORD-19 |

Based on the latest developments of the digital content industry in China, this paper probes into the market development, competitive landscape, investment and financing volume, investment hotspots, policies and public opinion environment of 10 sub-sectors, including online games, animation, online videos, short videos, live streaming, online music, digital reading, news & information apps, online education, and knowledge payment, provides an insight into the status quo of China’s digital content industry in 2020–2021 and ten major development trends of the industry. Furthermore, the investment value of 10 sub-sectors is assessed from two dimensions—internal factors and external factors, with a total of 7 primary indicators and 11 secondary indicators, and the results are compared with those of the previous two editions to observe market changes. Research conclusions are as follows: (1) From the perspective of development trends: the scale expansion of China’s digital content industry has slowed down; short videos continue to increase; user value operation becomes a new test under routine pandemic prevention and control; the competitive landscape among sub-sectors tends to be stable; leading enterprises expand their business territory via investment, merger and acquisition (M&A) for the integration of upstream and downstream industrial chain. (2) From the results of investment value assessment and investment trends: live streaming and online games lead the way of investment forward in the digital content industry, thanks to their mature cash realization model and huge market space, with the investment value ranking rising to the top two; in the video field, vertical content creation of short video, online video-related intelligent technology and digital marketing are worthy of attention; and in the digital reading field, focus can be placed on original content creation and novel/comic reading platforms. | N/A | 2022 | | CORD-19 |
| 2013 | Raising Awareness About Geoheritage at Risk in Portugal: the GeoXplora as a Case Study This work reports an innovative event developed at the University of Coimbra (Portugal) and organized by undergraduate students of geology during the academic year 2020/2021 regarding geological heritage at risk outcropping in the Lusitanian Basin. Inspired by the current situation of vulnerability of two well-known geosites classified as Natural Monuments (Carenque and Cabo Mondego), the GeoXplora initiative targeted the general public, decision-makers and politicians. It aimed at stimulating curiosity and interest about geoconservation, raising awareness about the need to protect the physical integrity of both geosites and requiring the implementation of appropriate valuing and monitoring actions as provided by the Portuguese legislation. Based on a webinar format, the event was free of charge and took an entire day (April, 16th, 2021). It included four thematic sessions led by 21 experts from different sectors of the society. The social impact of this initiative was analyzed through data collected from two applications: Meta Business Suite© of the Facebook event page, and a survey included in the event registration form using the Google Forms©. Results show that more than 10,000 participants affiliated to different organizations attended the initiative, numbers that would hardly have been achieved with a traditional face-to-face seminar. They accessed from several countries around the world, with significant participation of people from the Community of Portuguese-Speaking Countries. The results relate to a study case, but the event design and implementation may be useful for inspiring other students, teachers and communities to develop similar interventions aiming at raising awareness about the role of geosciences in promoting sustainable development, and taking the 2030 Agenda goals into account. | N/A | 2022 | | CORD-19 |

| 2015 | Good response to plasmapheresis and mycophenolate mofetil in a patient with anti-synthetase syndrome associated with peripheral neuritis and severe prosthetic aortic valve stenosis BACKGROUND: Idiopathic inflammatory myopathies (IIM) are a disease complex that encompasses several distinctly acquired muscle illnesses. Anti-synthetase syndrome is a subset of IIM that is characterized by the presence of antibodies against aminoacyl-tRNA synthetases (ARS). This syndrome has a characteristic phenotype of IIM. Anti-synthetase syndrome was rarely associated with peripheral nerve involvement and endocarditis. CASE PRESENTATION: We report a 46-year-old female patient with a history of mitral and aortic valve replacement for seven years and on warfarin, presented with symmetrical muscular weakness, generalized edema, progressive dyspnea, dysphagia, fever, fatigue, myalgia, and polyarthralgia. The motor power grading was 2 in proximal muscles of upper limbs and 3 in the distal muscles involving hands and wrists, and it was 0 in proximal muscles in lower limbs and 2 in distal muscles involving ankle and toes movements. Also, her oxygen saturation decreased remarkably. Echocardiography revealed that the patient had severe stenosis (70%) of the prosthetic aortic valve. Electrophysiological studies showed axonal polyneuropathy with average F wave latencies. She was diagnosed with anti-synthetase syndrome for elevated muscle enzymes, interstitial lung disease (ILD), mechanic’s hands, fever, polyarthralgia, and positive anti-Jo-1 antibody. There was a significant improvement with plasmapheresis, mycophenolate mofetil (MMF), and high-dose prednisolone. CONCLUSIONS: To the best of our knowledge, this is a case of anti-synthetase syndrome accompanied by neuropathic involvement and cardiac valve prosthetic stenosis. These were reported as an unusual presentation of the anti-synthetase syndrome. The significant improvement with plasmapheresis gives us a treatment choice for similar critical cases. | N/A | 2022 | | CORD-19 |
| 2016 | Can e-commerce platforms build the resilience of brick-and-mortar businesses to the COVID-19 shock? An empirical analysis in the Chinese retail industry We proposed a research model that examined the differences between the contributions of large, third-party e-commerce platforms and self-operated e-commerce platforms to businesses’ resilience to the COVID-19 shock. The difference-in-differences approach was employed to analyze a substantial sample of Chinese retailers. The study found that (1) under the baseline condition, the large, third-party e-commerce platforms built significant resilience for the brick-and-mortar businesses, (2) resource constraints induced by factor immobility weakened the contribution of large, third-party e-commerce platforms to the businesses’ resilience in regions of severe shock, and (3) the physical retailers’ self-operated EC platforms built resilience in regions of severe shock. | N/A | 2022 | | CORD-19 |
| 2017 | Blockchained education: challenging the long-standing model of academic institutions The model of higher education institutions has remained widely unchallenged over time. Although study topics keep evolving and the inclusion of increasingly sophisticated technologies have revolutionised the format of lectures and learning experiences. Their value chain remains unchanged, with institutions acting as intermediaries, between professors (knowledge) and students (recipients), and as central authorities granting and validating student knowledge. The work here presented is a review of blockchain technology and its application in education, emphasising the opportunities for disrupting the current value chain of academic institutions. Blockchain technology’s prime novelty constitutes an incorruptible digital ledger of transactions, capable of recording virtually any nature of value exchange. When coupled with other emerging technologies such as the internet of things and big data, new paths for the decentralised exchange of education and recording of knowledge and skills appear. The result is an extensive analysis of the evolution of blockchain technology for education applications, along with a forecast of plausible scenarios of disruption for academic institutions. Blockchain technology is steadily advancing at accelerating rates; applications aimed at decentralising educational institutions are already available. Meanwhile, the technology keeps gaining momentum in a growing base of adepts. | N/A | 2022 | | CORD-19 |

| 2020 | Clinical Characteristics and Risk Factors of Liver Dysfunction in COVID-19 Patients BACKGROUND: COVID-19 outbreak has spread around the world. Liver dysfunction (LD) was related with high mortality in COVID-19. METHODS: Retrospective, single-center study case series of 425 consecutive hospitalized COVID-19 patients were enrolled. Demographic, clinical, laboratory, and treatment data were collected. RESULTS: A total of 425 patients were included in this study, 145 of whom had LD. The overall mortality rate was 8.9%, while 17.9% in the LD group and 4.3% in the nonliver dysfunction (NLD) group. Age, sex, and hypertension were the independent risk factors of LD. LD was an independent risk factor for incidence of severe illness, acute respiratory distress syndrome, and death. The survival rate of patients in LD group was lower than that in NLD group (P < 0.001). A similar trend was observed by the multivariate regression analysis (adjusted hazard ratio, 3.52; 95% confidence interval [CI], 1.69–7.33; P = 0.001). Angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers had effect to reduce LD (odds ratio of 0.48 [95% CI, 0.232–0.989; P = 0.045]). CONCLUSIONS: LD is one of the main features of hospitalized patients of COVID-19, with a worse prognosis. Patients of COVID-19 with LD on admission should be more cautions. | N/A | 2021 | | CORD-19 |

| 2023 | Differential Effects of Angiotensin-Converting Enzyme Inhibitors and Angiotensin II Receptor Blockers on COVID-19 BACKGROUND: The effect of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs) on the coronavirus disease 2019 (COVID-19) remains controversial from clinic evidence. OBJECTIVES: The objectives of this study were to report the major characteristics and clinical outcomes of COVID-19 patients treated with ACEIs and ARBs and compare the different effects of the two drugs for outcomes of COVID-19 patients. METHODS: This is a retrospective, two-center case series of 198 consecutive COVID-19 patients with a history of hypertension. RESULTS: Among 198 patients, 58 (29.3%) and 16 (8.1%) were on ARB and ACEI, respectively. Patients who were on ARB or ACEI/ARB had a significantly lower rate of severe illness and acute respiratory distress syndrome (ARDS) when compared with patients treated with ACEI alone or not receiving RAAS blocker (P < 0.05). The Kaplan–Meier survival curve showed that patients with ARB in their antihypertensive regimen had a trend toward a higher survival rate when compared with individuals without ARB (adjusted hazard ratio, 0.27; 95% confidence interval [CI], 0.07–1.02; P = 0.054). The occurrence rates of severe illness, ARDS, and death were similar in the two groups regardless of receiving ACEI. The Cox regression analyses showed a better survival in the ARB group than the ACEI group (adjusted hazard ratio, 0.03; 95% CI, 0.00–0.58; P = 0.02). CONCLUSIONS: Our data may provide that some evidence of using ARB, but not ACEI, was associated with a reduced rate of severe illness and ARDS, indicating their potential protective impact in COVID-19. Further large sample sizes and multiethnic populations are warranted to confirm our findings. | N/A | 2021 | | CORD-19 |
| 2024 | Corticosteroids Utilization in the Management of Critically Ill COVID-19 Pneumonia BACKGROUND: There are controversies regarding corticosteroids using in coronavirus disease-2019 (COVID-19) pneumonia in the current pandemic. OBJECTIVES: This study investigates the efficacy and safety profiles of corticosteroids therapy in COVID-19 patients. METHODS: Retrospective, multicenter study case series of consecutive patients with confirmed COVID-19 infection at the whole hospital from January 1 to March 1, 2020, were enrolled. Demographic, clinical, radiological, laboratory, and treatment data were collected and analyzed. The effect of corticosteroids therapy on death and organ-failure complications of pneumonia were analyzed by logistic regression. RESULTS: A total of 470 COVID-19 patients at the whole hospital were enrolled. According to the time of corticosteroids initiation and severity of illness, there were 159 patients stratified into critical ill group and 64% (102 of 159) patients received corticosteroids treatments. Ninety-four percent (166 of 176) of corticosteroids were methylprednisolone. The median cumulative corticosteroids dosage was 300 mg equivalent of methylprednisolone over a median duration of 6 days. Multivariate regression analysis showed that corticosteroids use did not affect the mortality. However, corticosteroids therapy at moderate cumulative doses (total exposure 480 mg to 1200 mg) was associated with deceased occurrence of organ-failure complications in critically ill COVID-19. CONCLUSIONS: Corticosteroids have no effect to mortality in COVID-19 patients. The moderate cumulative doses of corticosteroids might decrease organ-failure complications in critically ill COVID-19. Further large-scale randomized controlled trials are warranted to confirm our findings, until then use of corticosteroids should be used with caution COVID-19 patients. | N/A | 2022 | | CORD-19 |
| 2025 | Giant Inverse T-wave in a Patient with COVID-19 It has been described that COVID-19 is a dynamic behavior and systemic affectation entity, so it is essential to develop the diagnostic and prognostic tools which allows to specifically identify target organ damage. The electrocardiographic finding of an inverse T-wave suggests transient apical dysfunction of the left ventricle, generating confusion among different heart diseases. However, despite the lack of troponin elevation and other myocardial injury signs, this finding is unspecific, especially in the patient with COVID-19. The aim of this manuscript is to present the case of a patient with COVID-19 without a previous diagnosis of heart disease, which manifests an isolated inverse T-wave. | N/A | 2021 | | CORD-19 |
| 2026 | Clinical Characteristics and Risk Factors for Acute Kidney Injury in COVID-19 OBJECTIVE: The objective of the study is to describe the clinical characteristics, risk factors, and prognosis for acute kidney injury (AKI) among patients with coronavirus disease (COVID-19). METHODS: Retrospective study of 456 consecutive patients with confirmed COVID-19 infection at the whole hospital from January 1 to March 1, 2020 was enrolled. Demographic, clinical characteristics, the risk factors, and prognosis were collected and analyzed. RESULTS: Of 456 patients with COVID-19, 38 patients developed AKI. Patients with AKI were older and predominantly male sex and were more likely to have comorbidities such as hypertension, cardiovascular, and cerebrovascular diseases. Among patients with AKI, the white blood cell count, neutrophil count, neutrophil-to-lymphocyte ratio, alanine aminotransferase, and C-reaction protein were increased, and lymphocyte and platelet count were decreased. Multivariate analysis showed that age, hypertension, and lymphocyte count were independent risk factors for AKI. The overall mortality rate of 456 patients was 9.9%, and the mortality rate of patients with AKI was 23.7%. In particular, increasing AKI severity was associated with increased risk. CONCLUSIONS: The risk of AKI was high in patients with COVID-19. Older age, hypertension, and lower lymphocyte count were independent risk factors for AKI. COVID-19-associated AKI was associated with higher risk of death in patients with COVID-19. | N/A | 2021 | | CORD-19 |
| 2027 | Exploration and Thinking in Mixed Flipping-Classroom Teaching Approach on Clinical Endocrinolgy during the COVID-19 Period BACKGROUND AND OBJECTIVES: To explore the superiority of flipping-classroom lended learning in which the stay-home e-learning and traditional internship complements each other in resident training of endcorinology during coronavirus disease 2019 restriction period. MATERIALS AND METHODS: A total of 44 residents were randomized as the study population. In the endocrine-rotation training, we reformed the clinical learning by unified online-teaching led by teachers' combination with individual guidance by residents. Moreover, the final implementation assessment was conducted by standard double-blind examinations. RESULTS: After 4–8 weeks training, the 44 residents were assessed for clinical skills from six dimensions, including medical history collection, physical examination, history report and inpatient record writing, case analysis, and overviewing capability. Compared with the mean scores of 68 residents rotated in internal medicine in 2019, the mean scores on physical examination, inpatient record writing, and overviewing capability in 2020 group were higher with significance ([85.72 ± 8.33] vs.[79.22 ± 10.12], P = 0.0006), ([90.28 ± 10.70] vs. [81.82 ± 8.03], P < 0.0001), ([80.31 ± 8.70] vs. [73.04 ± 12.74], P = 0.0012), whereas scores on skills of medical history collection and history report were slightly lower ([82.11 ± 9.02] vs. [85.06 ± 7.23], P = 0.0586), ([79.30 ± 8.17] vs. [83.21 ± 5.01], P = 0.0022), while scores on case analysis did not show huge gap but with polarized performance in 2020 group ([74.38 ± 10.29] vs. [78.13 ± 8.53], P = 0.0386). CONCLUSIONS: Providing the novel pattern of unified online-teaching combined with individual-guidance at the bedside to the front-line residents can reduce the risk of cluster epidemics and effectively ensure the training effect on them but still with shortcomings. The future online teaching reform is better for focus more on how to make up for or reduce the actual problem of disconnection between theory and practice in the process of online clinical skills training for residents and teachers. | N/A | 2021 | | CORD-19 |

| 2032 | The transformative potential of banking service domains with the emergence of FinTechs Most activities of FinTech companies in the real world are limited to a variety of banking services such as payment and funds transfer, while the scope of banking services is much broader than the current activities of FinTech companies. In recent years, extensive research has also been conducted on how FinTech companies contribute to the provision of banking services. The present study identifies ideas for new and innovative areas of FinTech companies’ activity by reviewing the relevant literature. These areas are categorized using the Banking Industry Architecture Network (BIAN) service landscape and are identified and described through thematic analysis. The outcome of this study is a model which reveals that the main service domains belong to the “banking operations and execution,” “sales and services,” “risk and compliance,” “business support,” and “reference data.” According to the findings of the present research, FinTech companies have the capability to provide banking services in 22 domains out of 36 BIAN domains. Theoretical contributions and comparative analysis are discussed. | N/A | 2022 | | CORD-19 |
| 2033 | „Durch die Coronapandemie belastet?" Der Einfluss von durch COVID-19 induzierter Angst auf die sozial-emotionale Entwicklung 12- bis 13-Jähriger in Österreich During the COVID-19 pandemic, students have been severely affected by measures such as school closures and homeschooling. While it is obvious that these measures influenced students’ academic achievement, there is also reason to believe that students’ social-emotional development has been impacted. The present study investigates (1) the extent to which students in Austrian secondary school (12 to 13 years old) feel stressed by the COVID-19 pandemic, and (2) how the different levels of stress affect their social-emotional development. The focus of this study is on the development of problematic behavior (internalized and externalized behavior problems) and prosocial behavior. In total, 774 students participated in the study and 650 students took part in three different times of measurement, with the last time of measurement taking place just before the second school closure as a measure in the COVID-19 pandemic. Almost 20% of the respondents show higher stress-levels in terms of COVID-19 induced anxiety. Students with higher stress-levels also display a more negative development in their internalized behavior problems. Likewise, for students’ development of externalized behavior problems, a trend in this direction was demonstrated, yet less pronounced. Students who reported a higher stress-level also developed more prosocial behavior. Yet, we could not statistically verify this due to violation of statistical prerequisites. | N/A | 2022 | | CORD-19 |
| 2034 | Dynamic Interaction of COVID-19 Incidence and Stock Market Performance: Evidence from Nigeria The incursion of COVID-19 into global space has constituted both public health emergency and economic crisis, thus there is need to investigate the transmission of inherent uncertainty associated with the pandemic on stock markets. Based on this, this study investigates the dynamic interaction of COVID-19 incidence and stock market performance in Nigeria. The study uses daily time series data between 2/4/2020 and 8/8/2020 of All Share Index (ASI), COVID-19 pandemic confirmed cases, Nigerian borrowing rate and exchange rate to conduct the analysis. Sequel to careful econometric investigation of data, vector autoregressive model was adopted for estimation due to the dynamic nature of the study. The estimation results show that the lagged value of COVID-19 infections exerts negative impact on ASI; specifically, a unit increase in COVID-19 infections causes ASI to fall by 0.066%. Similarly, the lagged value of ASI exerts negative impact on COVID-19 cases. Equally notable, a unit increase in ASI causes covid-19 cases to fall by 0.02% though it is not statistically significant. The study concludes that COVID-19 has a negative effect on Nigerian stock market performance; therefore, apart from small and medium enterprises government may need to extend stimulus package to public quoted firms as part of the efforts to bring the economy back on track. | N/A | 2022 | | CORD-19 |
| 2035 | Industrial Smart Working: a socio-technical model for enabling successful implementation With the spread of the COVID-19 pandemic, many companies have been pushed to re-think their traditional working models to comply with the need for social distancing. In this context, Smart Working practices have been proposed to re-arrange the workforce activities ensuring the minimization of risks as well as business continuity. Despite traditionally most of the smart working practices have been applied to white collars job profiles, the COVID-19 pandemic opened the way to the introduction of Smart Working practices also in the factory environments, introducing the concept of Industrial Smart Working (ISW). This paper aims at contributing to the development of the concept of ISW proposing a socio-technical model discussing the main enabling factors that can support the successful industrial implementation of time and space flexible working models. | N/A | 2022 | | CORD-19 |

| 2044 | COVID-19 and bank performance in dual-banking countries: an empirical analysis We explore how banks’ income and stock prices respond to the COVID-19 policy measures in countries with the dual-banking system, and whether Islamic banks over- or underperform compared to conventional banks. Applying two-way fixed-effect regressions, we document that the changes in Islamic banks’ finance income as well as net income decline as much during the COVID-19 pandemic as the changes in interest and net income of conventional banks. Event-study tests show that the stock prices of Islamic banks respond as negatively as the ones of conventional banks to workplace closures. We do, however, document that the two types of banks respond differently to income support schemes. The change in Islamic banks’ finance income and net income increase significantly more compared to that of their conventional peers when governments install income support initiatives. Also, Islamic banks’ stock prices respond more positively to the income support programs than the ones of conventional banks. Because we control for investment banking activities and services to large clients, our findings on the stronger response of Islamic banks to income support programs seem to result from Islamic banks’ focus on private customers who are supported during the pandemic. Overall, we conclude that the Shariah compliance does not limit the adverse impact of the COVID-19 crisis on Islamic banking, but that Islamic banks’ performance responds more positively to income support initiatives than the one of conventional banks. | N/A | 2022 | | CORD-19 |
| 2045 | Moderating and mediating effect of perceived experience on merchant's behavioral intention to use mobile payments services The current study aims to determine the factors influencing the behavioral intention of merchants to use mobile payment services (MPS). The study surveys 215 Indian merchants from a personally administered online survey process. The study includes six factors, namely: perceived ease of use, perceived usefulness, perceived experience, perceived cost, perceived trust, and word of mouth learning to measure the merchant’s intention with mobile payment service. The study also tested the mediating and moderating effect of perceived experience in the relation between word-of-mouth learning and the merchant’s intention. Perceived usefulness of MPS influences perceived experience, followed by perceived ease of use. The result concludes that the perceived experience is the most influencing variable, followed by word-of-mouth learning to influence merchant’s intentions to use MPS both directly and indirectly (significant mediating and moderating effect). The study offers few implications to banks, finance companies, payment companies to understand factors driving merchants’ intention to use MPS. | N/A | 2022 | | CORD-19 |
| 2046 | Medium-term consequences (5 years) of the Covid-19 crisis on work organization and occupational risks: a prospective study The health crisis linked to Covid-19 has had the effect of strongly increasing the activity of certain trades or, on the contrary, decreasing it to the point of stopping. It has also disrupted the organization of work in companies: remote work, physical distancing, etc. The question that now arises is to know the sustainability of these developments, their influence on working conditions, and the associated occupational risks. To do this, a prospective study was conducted involving the reference body for occupational risk prevention in France (INRS), a prospective think tank (Futuribles), representatives of a dozen French companies, and a number of experts on these issues. | N/A | 2022 | | CORD-19 |
| 2047 | Meeting the research(er) and the researched halfway How can we investigate something so indeterminate, unpredictable and enormous, as the current Covid-19 pandemic? We apply Karen Barad’s relational ontology to illuminate some current dilemmas in research, where different forces, concepts and theories conflict with one another in multiple and complex ways. Barad’s views, we argue, may help to address potential dilemmas of accountability, for instance of accounting research(ers) as they research the Covid-19 pandemic. In what Barad calls ‘intra-action’, the research apparatus, the researched phenomena,andthe research results, constitute a complex system of relatedness. In ‘intra-action’ these elements never fully melt into one another, but rather, retain their ontological individuality. The research apparatus creates ‘real’ effects, but these can only be partially observed and disentangled. Which elements intra-act as the research progresses is the product of so-called ‘agential cuts’. We have researched the Covid-19 pandemic via what Barad would call a (small-scale) ‘experiment’. We have focused on air travel and more specifically on American Airlines: a hyperobject or social-economic object so complex and powerful that it cannot be captured in any single definition or analysis. Among others, we take guidance from Albert Camus’ The Plague in our analysis, concluding that AA (as a hyperobject) cannot really meet the research(ers) halfway, as Barad would call for. This is because the mutuality of ‘intra-action’, that is demanded is foreclosed. Consequently, while we believe that Barad’s views hold great merit for accounting research in the current crisis, we suggest that they raise deeply troubling dilemmas as well. | N/A | 2022 | | CORD-19 |
| 2048 | How did COVID-19 change what people buy: Evidence from a supermarket chain This research takes a retrospective view of the COVID-19 pandemic and attempts to accurately measure its impact on sales of different product categories in grocery retail. In total 150 product categories were analyzed using the data of a major supermarket chain in the Netherlands. We propose to measure the pandemic impact by excess sales – the difference of actual and expected sales. We show that the pandemic impact is twofold: (1) There was a large but brief growth at 30.6% in excess sales associated with panic buying across most product categories within a two-week period; and (2) People spending most of their time at home due to imposed restrictions resulted in an estimated 5.4% increase in total sales lasting as long as the restrictions were active. The pandemic impact on different product categories varies in magnitudes and timing. Using time series clustering, we identified eight clusters of categories with similar pandemic impacts. Using clustering results, we project that product categories used for cooking, baking or meal preparation in general will have elevated sales even after the pandemic. | N/A | 2022 | | CORD-19 |
| 2049 | Questioning the spatial association between the initial spread of COVID-19 and transit usage in Italy Within the much broader framework of global interest, the dilemma concerning the real impact of mode of transport on the spread of COVID-19 has been a priority for transport stakeholders and policy-makers. How dangerous is it to move around a certain territory? Does the danger depend on the mode of transport? By considering a novel and detailed dataset at the level of local labour markets, we analysed the spatial association between the pre-pandemic propensity to use public transport and excess mortality in Italy attributable to the initial spread of COVID-19. We found that places characterised by larger commuting flows exhibit higher excess mortality during the first wave of the pandemic, but observed no significant spatial association between excess mortality and transit usage. Our results were obtained by considering a wide range of heterogeneity in the estimation of quantile regressions across a variety of specifications. Although we do not provide a definitive answer concerning the risk associated with transit use, our analysis suggests that mobility, not modal choice, should be considered a main driver of the initial contagion. | N/A | 2022 | | CORD-19 |
| 2050 | Integrated analysis of the Mexican electricity sector: Changes during the Covid-19 pandemic The COVID-19 pandemic has nonlinear impacts. These impacts have collaterally affected systems such as economic and energy. The fragility of these systems has also been shown, including the electric system. In Mexico, the weakness of dependence on US fuels, of the transmission system, and the management reduction of one of the most crucial state companies in Mexico, the Federal Electricity Commission (CFE), was evidenced. The changes during the COVID-19 pandemic were the decrease in electric demand and consumption. This prevented the transmission nodes from saturating, although about 15% of the energy generated was still lost. Private companies, which own most of the intermittent renewable generation, and natural gas have been favored by the changes during the COVID-19 pandemic, generation sources such as wind aand solar have had a noticeable increase, because of the 2013 energy reform that created an electricity market in which private companies and the state company started to compete. On the other hand, during the 2020 winter, natural gas imported mostly from the United States had volatile prices, considerably increasing its cost, and putting the combined cycle generation at risk. This technology represents around 60% of the generation, and its primary owners are private companies. This situation led to great discussions in the current administration, thus originating an electricity reform in which the state company wants to have control again. This paper opens the debate on whether the Mexican electricity system should continue with the same generation pattern or make substantial changes that benefit the country's energy security, distributed generation, and the relationship between the state company and the Mexican electricity system. | N/A | 2022 | | CORD-19 |
