ABSTRACT

Objectives: Since the COVID-19 pandemic, the potential for vaccines to reduce pressure on health care systems has received much attention. However, evaluation of how vaccination may impact health system pressure is hindered by lack of a formal definition and measurement framework. We developed an approach for defining health system pressure and measuring its impact in healthcare settings and applied this approach to respiratory syncytial virus (RSV) and Clostridioides difficile (C. difficile) infections. Methods: We conducted a targeted literature review and assessed hospital guidelines for prevention and control of RSV and C. difficile infections in hospital settings in Germany, Italy, and the UK. The definition and framework were tested via semi-structured interviews among healthcare professionals. Results: Health system pressure can be generally defined as resource utilisation given a pre-set usable capacity. Its impact can be measured as the opportunity cost of actions taken to prevent or mitigate pressure. Actions to prevent or mitigate pressure due to RSV or C difficile can be classified by their impact on staff (labour resources), stuff (non-labour resources and materials), and structure capacity. Increased staffing needs drive RSV pressure during the RSV respiratory season and are considered to be extremely likely and extremely costly by 75% of the interviewees. C. difficile pressure is driven by the activation of outbreak-induced infection control protocols, which are likely to affect every capacity dimensions according to over 60% of the interviewees, and lead to large costs of infrastructure needed to isolate patients. In general, actions to mitigate pressure are associated with higher costs than actions used to prevent pressure before it occurs. Conclusions: This research describes a novel definition and framework for health system pressure. Further development and application of this framework may enable HTA bodies to describe and measure the potential impact of vaccination on health care systems.

ABSTRACT

The growth of distance learning in higher education has been gaining market share. The COVID-19 pandemic has reinforced this trend. Enrollments are increasing sharply while fierce competition is a threat to distance learning institutions. To conquer and retain distance learning students, it is necessary to offer quality services and products, seeking innovation and continuous improvement to meet their needs. However, studies that analyze the application of the principles and practices of TQM (Total Quality Management) in distance higher education are still scarce. From this perspective, this study seeks to identify practices that increase the presence of TQM principles in distance higher education institutions. The qualitative research was carried out with managers from 64 teaching centers of one of the largest distance learning institutions in Brazil. The pillars of TQM considered in this study are leadership, staff, students, technological resources and continuous improvement. This study contributed to the literature by identifying practices to expand the presence of TQM principles in distance higher education adopted by the studied institution and its teaching centers. Management contributions are also presented. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

The COVID-19 pandemic had a strong impact on Portuguese society and raised the need for new technological projects to help frontline professionals in the fight against coronavirus and its effects on the local population and economic agents. It is in this context that the Tech4Covid19 movement was founded by Portuguese technological startups. This initiative brings together more than 5000 volunteers and offers technological solutions in the areas of health, education, and local economy. This study aims to understand and explore the organizational model and dynamics of Tech4Covid19 through the adoption of qualitative methods based on primary and secondary sources that have allowed the movement to be explored from multiple perspectives. The findings reveal that Tech4Covid internally promotes the development of its own projects, but also accepts projects proposed by external entities that are aligned with the principles and values of the movement. The organization of the movement is supported by autonomous self-managed teams regarding each project, and there is a coordination group responsible for the aggregate management of the various initiatives and for establishing communication with partners, the media, and social networks. © Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0).

ABSTRACT

Purpose: This study aims to explore the role open data assumes in social innovation initiatives that combat the effects of Covid-19, in which quantitative information about these projects is complemented with the analysis of open data innovation capabilities. Methodology: A mixed methods approach is adopted. Initially, quantitative data regarding the number of innovative projects is extracted from the OPSI framework. Then, in a second phase, qualitative data from each project is explored to explore the open data innovation capabilities offered by each initiative. Results: The results reveal that most social innovation initiatives focus on the area of data visualization dashboards and open datasets. However, some projects address other areas, e.g. hackathons, service availability, and tourism information. Implications: Covid-19 profoundly affects the lives of people and businesses, and open data can assume a determinant role in mitigating these effects and improve information transparency and collaboration between public and private entities. Originality/Value: This study is relevant for the establishment of supportive public policies that promote the emergence of open-data-driven initiatives to mitigate the effects of Covid-19 in several areas such as the economy, education, and leisure.

ABSTRACT

We apply a generalized logistic growth model, with time-dependent parameters, to describe the fatality curves of the COVID-19 disease for several countries that exhibit multiple waves of infections. In the case of two waves only, the model parameters vary as a function of time according to a logistic function, whose two extreme values, i.e., for early and late times, characterize the first and second waves, respectively. For the multiple-wave model, the time-dependency of the parameters is likewise described by a multi-step logistic function with N intermediate plateaus, representing the N waves of the epidemic. We show that the theoretical curves are in excellent agreement with the empirical data for all countries considered here, namely: Brazil, Canada, Germany, Iran, Italy, Japan, Mexico, South Africa, Sweden, and the USA. The model also allows for predictions about the time of occurrence and severity of the subsequent waves. It is shown furthermore that the subsequent waves of COVID-19 can be generically classified into two main types, namely, standard and anomalous waves, according as to whether a given wave starts well after or well before the preceding one has subsided, respectively. © 2021, The Author(s), under exclusive licence to The Author(s) under exclusive licence to Sociedade Brasileira de Física.

ABSTRACT

Objetivo: O presente estudo buscou analisar a suscetibilidade pela infecção por SARS-CoV-2 entre a tipagem sanguínea com base em estudos publicados. Introdução: O SARS-CoV-2 é um vírus pertencente à família dos Coronaviridae, tendo o RNA como seu material genético, que leva ao desenvolvimento da doença COVID-19. O novo coronavírus foi detectado pela primeira vez em dezembro de 2019 na cidade de Wuhan, China, tornando-se uma pandemia acometendo até agosto de 2020, 215 países. Neste sentido, a busca por entender os mecanismos e/ou suscetibilidade frente a infecção por este vírus, se tornou prioridade entre os pesquisadores do mundo, sugerindo então uma correlação entre o sistema ABO frente a infecção por SARS-CoV-2. Metodologia: Foi realizada uma revisão da literatura com base em artigos indexados nas plataformas: Pubmed e medRxiv, no ano de 2020. Ao final da aplicação dos critérios de exclusão para seleção dos artigos, foram selecionados 17 estudos. Resultados e discussões: Mesmo com a escassez de estudos, o que é justificável por se tratar de um novo vírus, as pesquisas apontam que o tipo A é o mais susceptível e o grupo O menos susceptível, todavia, a gravidade quanto ao risco de óbito está associado ao tipo AB. Até o presente momento não se sabe ao certo o porquê o SARS-CoV-2 é menos susceptível ao grupo O. Hipotetiza-se que o anti-A desse grupo é capaz de interferir na ligação entre a proteína Spike com o receptor da enzima conversora angiotensina 2 (ACE2), mecanismo este visto na infecção por SARS-CoV-1. Outro fato que pode ser considerado é em relação a neutralização que os anticorpos anti-A e/ou anti-B podem exercer em infecções virais semelhantemente visto nas infecções por HIV, que poderia neutralizar também o SARS-CoV-2. Conclusão: Em suma, nota-se que o tipo sanguíneo O apresenta uma menor suscetibilidade diante a infecção pelo novo coronavírus, porém, não há nenhum estudo que elucide de qual forma o SARS-CoV-2 se porta diante o grupo ABO, fazendo então a necessidade de pesquisas para esclarecer este processo.

ABSTRACT

The pandemic caused by the new coronavirus (SARS-CoV-2) imposed a worldwide scenario of social isolation and suspension of face-to-face teaching activities at all levels of education. It has forced the emergency adoption of remote teaching strategies to maintain the continuity of the didactic activities, even though in a limited way. On the other hand, most teachers, at all levels of education, had barely or no knowledge and experience with remote teaching. Although the educational institutions offered support, to some degree or another, it was up to individual teachers to do most of theirselves training, prepare, and deliver their subjects. Also, many courses were migrated to the virtual learning environment without the proper adaptations, which may result in worse learning outcomes. Although there are different methodologies for planning and implementing e-learning, the ADDIE model is largely popular and relatively simple to implement, and for this reason, it was chosen for the development of this article. Thus, we present the steps of analysis, design, development, implementation, and evaluation of a remote course. Additionally, we include practical elements such as an indication of equipment, software, links, and suggestions to accomplish these steps.

ABSTRACT

The COVID-19 pandemic caused profound impacts arising from a traditional on-site teaching model rupture and demanded distance learning for Engineering students, who faced additional challenges and opportunities for practical activities with physical components such as Internet of Things projects. As an alternative to standardized synchronous tests, Project Based Learning (PBL) was employed in this context to engage students in the social distancing context. This paper presents experiment reports of PBL application for the Polytechnic School of the University of São Paulo’s Computer Engineering curriculum in 2020: two undergraduate courses (third year’s Digital Laboratory II, fifth year’s Laboratory of Software Engineering II), scientific initiation (short-term research project of smart meter for third year student), and capstone project (one year project fifth year student regarding smart home monitoring). In all courses, at least a Master of Science student acted as co-advisor or graduate teaching assistant. When combined with remote labs, home labs and virtual labs, PBL could engage students and make practical activities happen during the pandemic. The students took an active part in the projects, working with stakeholders and raising demands for tools usage. © 2021 University of Minho. All rights reserved.

ABSTRACT

Purpose This study aims to explore worldwide innovative solutions that have been proposed to mitigate the effects of COVID-19 pandemic on people's mental health. Design/methodology/approach A qualitative methodology is adopted, which performs an exploratory study considering the innovative projects identified by the Observatory for Public Sector Innovation framework. Additionally, the analysis of the relevance and characteristics of these projects are explored considering a multidimensional framework composed of five dimensions: novelty level;social need;improvement of society;sector neutrality;and level of emergence. Findings The findings reveal that the number of projects in the field of mental health is low, despite their strong relevance to their communities. These projects arise from a strong social need to protect especially the most vulnerable groups in this pandemic and involve a large number of partners in the public sector, business and civil society. The role of volunteering in the revitalization and growth of these initiatives is also recognized. Originality/value This study is relevant in both the theoretical and practical dimensions. It allows the exploration of these projects considering the dimensions of social innovation and offers practical implications that allow these projects to be replicated in other countries and regions.

ABSTRACT

According to data from the Brazilian Association of Cotton Producers, Brazil occupies 4th place in the ranking of cotton production according to the 18/19 harvest. Because of this importance, this review aimed to carry out a bibliometric survey on cotton oil and flour and their applications. The results showed that there were a total of 1525 research and reviews articles in the Scopus and Web of Science databases in the last three decades, and, based on the entire analysis, it was noticed that the studies of the last three decades are focused on separation area and biofuels, as well as that the Republic of China stands out among the most cited countries besides its universities. According to these results, it can be concluded that the Republic of China has a lot of influence in studies with cotton and more research is needed to use cotton and its derivatives in the food industry.

ABSTRACT

Sentiment Analysis techniques enable the automatic extraction of sentiment in social media data, including popular platforms as Twitter. For retailers and marketing analysts, such methods can support the understanding of customers' attitudes towards brands, especially to handle crises that cause behavioural changes in customers, including the COVID-19 pandemic. However, with the increasing adoption of black-box machine learning-based techniques, transparency becomes a need for those stakeholders to understand why a given sentiment is predicted, which is rarely explored for retailers facing social media crises. This study develops an Explainable Sentiment Analysis (XSA) application for Twitter data, and proposes research propositions focused on evaluating such application in a hypothetical crisis management scenario. Particularly, we evaluate, through discussions and a simulated user experiment, the XSA support for understanding customer's needs, as well as if marketing analysts would trust such an application for their decision-making processes. Results illustrate the XSA application can be effective in providing the most important words addressing customers sentiment out of individual tweets, as well as the potential to foster analysts' confidence in such support.

ABSTRACT

Purpose: The COVID-19 pandemic has significantly impacted the European Union (EU) through heavy pressure on health services, business activity and people's life. To mitigate these effects, government agencies, civil society and the private sector are working together in proposing innovative initiatives. In this sense, this study aims to characterize and explore the relevance of these projects to mitigate the effects of COVID-19. Design/methodology/approach: The Observatory of Public Sector Innovation provided by the Organization for Economic Co-operation and Development was considered to enable the identification and exploration of innovative projects to combat COVID-19. A methodology based on mixed methods is adopted to initially identify quantitatively the distribution of these projects, followed by a qualitative approach based on thematic analysis that allows exploring their relevance. Findings: A total of 206 initiatives in the EU have been identified. The distribution of these projects is quite asymmetric, with Portugal and Austria totaling 33.52% of these projects. Most of these projects focus on the areas of public health, infection detection and control, virtual education, local commerce, digital services literacy, volunteering and solidarity and hackathons. Originality/value: This work is relevant to identifying and understanding the various areas in which COVID-19 initiatives have been developed. This information is of great relevance for the actors involved in this process to be able to replicate these initiatives in their national, regional and local contexts. © 2021, Emerald Publishing Limited.

ABSTRACT

Portugal is a country in which the tourism sector assumes great importance, contributing around 15% of the national GDP and with more than 1 million jobs. In this sense, COVID-19 is expected to have a dramatic impact on the Portuguese economy aggravated by the existence of a reduced internal market with low purchasing power and in which there is a high dependence on the external market. This perspective study explores the challenges and opportunities that Portuguese companies in the field of tourism are facing due to the emergence of this pandemic. The challenges faced by companies are both short-term and long-term. In the short term, it is essential to ensure sufficient liquidity to reopen activities and in the long term, it is necessary to be prepared and reactive to disruptive movements that may arise in tourist demand. However, it is also important to recognize that some opportunities can be exploited, such as the quality of the health response, the exploitation of a less mass tourism supply based on the components of social and environmental sustainability, the increase of tourism among the elderly population from countries with greater purchasing power and the acceleration of the digitalization of tourism operations.

ABSTRACT

Purpose This study explores the contribution that tech startups can provide in the fight against COVID-19. The Tech4Covid movement is presented to that effect, which has joined several Portuguese tech startups. This initiative gathers more than 5,000 volunteers and 28 ongoing projects in several interdisciplinary areas, including science, technology, health and education. Design/methodology/approach Two qualitative methods are adopted: the case study and the field research technique. This joint approach allows exploring in-depth the relevance and impact of the different areas included in Tech4Covid movement. Data were collected both from primary sources, namely by the authors' participation in the movement and by the use of secondary sources from each project. Findings The findings reveal three main areas in which the 28 ongoing projects can be categorized, respectively: support to health professionals and hospital equipment, health and education services and business and leisure. These projects offer direct and indirect contributions to the fight against COVID-19. From a perspective, they were initially designed to support health professionals in gathering protective equipment and supporting screening for suspicious cases. From another perspective, they also offer indirect benefits to citizens and the local economy. Originality/value This paper addresses a recent phenomenon with a dramatic impact on public health, social and economic dimensions. The study provides essentially practical contributions by revealing how Portuguese technological startups were organized and worked together to respond to the COVID-19 pandemic. It is expected this study will serve as a reference for other countries and communities that intend to replicate this model.

ABSTRACT

COVID-19 has caused dramatic effects on the world economy, business activities, and people. But digitization is also helping many companies to adapt and overcome the current situation caused by COVID-19. The growth in the use of technology in the daily lives of people and companies to face this exceptional situation is an evidence of the digital acceleration process. This exploratory study analyzes the impact of digital transformation processes in three business areas: labor and social relations, marketing and sales, and technology. The impact of digitalization is expected to be transversal to each area and will encourage the emergence of new digital products and services based on the principle of flexibility. Additionally, new ways of working will foster the demand for new talent regardless of people's geographical location. Moreover, cybersecurity and privacy will become two key elements that will support the integrated development of the Internet of Things technology solutions, artificial intelligence, big data, and robotics.

ABSTRACT

Purpose: This short communication aims to explore and synthesize the main effects of COVID-19 on the labor market in Portugal regarding the dimensions related to job security and unemployment. Design/methodology/approach: Field research is used to identify and understand the challenges posed by the COVID-19 pandemic to the labor market in Portugal. Data from the National Institute of Statistics of Portugal are analyzed and compared with artifacts published in the field, which allow us to explore the impact of this phenomenon from multiple perspectives. Findings: The findings indicate that the impact on the labor market is very asymmetric regarding geographical regions, sectors of activity, age groups and the nature of labor ties. The most touristic regions and those with a strong dependence on the exterior are the most affected. Young people and women with unstable employment relationships and in temporary work situations are also particularly vulnerable. Originality/value: This study focuses on an emerging area with a strong impact of the COVID-19 pandemic on the labor market. This study seeks both to identify challenges in the Portuguese labor market and to discuss measures that should be taken to mitigate their effects, such as reforming the social security model, the role of teleworking or the more balanced development of the territory. © 2020, Emerald Publishing Limited.
