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
AbstractCOVID-19 has caused in Portugal an enormous economic, financial, and social challenge that must be answered by the national and local Portuguese government authorities. Several support measures have been launched to protect businesses, economic sustainability, and employment levels. At the national level, projects with greater economic emphasis are highlighted, which aim to support companies and their workers. The most noteworthy are measures relegated to simplified lay-off, social protection for individuals in isolation or with illness, and support for the payment of basic expenses such as electricity, water, and gas. Also, on this level, measures concerning teleworking and school at home through television have changed the daily lives of families. At the local level, there was a greater emphasis on the social dimension. The role played by local authorities and local councils in stimulating the local business community and supporting the creation of volunteer banks, the delivery of food and medicines, and the production of goods for individual protection was highlighted.

Abstract
<p><em>Investment in research and development is a key factor in increasing countries' competitiveness. However, its impact can potentially be broader and include other socially relevant elements like job quality. In effect, the quantity of generated jobs is an incomplete indicator since it does not allow to conclude on the quality of the job generated. In this sense, this paper intends to explore the relevance of R&amp;D investments for the job quality in the European Union between 2009 and 2018. For this purpose, we investigate the effects of R&amp;D expenditures made by the business sector, government, and higher education sector on three dimensions of job quality. Three research methods are employed, i.e. univariate linear analysis, multiple linear analysis, and cluster analysis. The findings only confirm the association between R&amp;D expenditure and the number of hours worked, such that the European Union countries with the highest R&amp;D expenses are those with the lowest average weekly working hours.</em></p>

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.
