Post-traumatic stress disorder (PTSD) is associated with risk of suicide and chronic psychological impairment. The continued exposure to stress suffered by health-care workers (HCWs) during the COVID-19 pandemic can be considered a mass traumatic event and contribute to higher rates of PTSD in this population. The purpose of this research is to find out the prevalence and factors associated with PTSD among HCW in a general hospital.

The authors devised a survey to assess the prevalence of PTSD among HCWs in a general hospital and its relationship with sex, social support, profession, work experience in health care, time spent caring for COVID-19 patients and place in which the COVID-19-related activities were carried out. PTSD symptoms were assessed using the PCL-5, Portuguese version.

A total of 226 HCWs were included in the study. Provisional diagnosis of PTSD was made based on the PCL-5 responses, considering DSM-5 criteria and the cutoff score of 33. In total, 79 (35.0%) HCWs had a provisional diagnosis of PTSD, and a significant association was found between PTSD and time spent working with COVID-19 patients and between PTSD and place of work, namely, the COVID-19 emergency room and intensive care unit.

The results highlight the need for a reflection on the importance of mental health promotion among HCWs, specially in adverse conditions such as the current pandemic.

The main aim of this chapter is to analyse whether recent economic developments in Central and Eastern European countries have been subjected to a typical process of Dutch Disease (DD). We investigate the impact of foreign aid and other external inflows on the economies of these countries through their effect on the real exchange rate (RER).

After a review of the literature on the DD, we apply robust new generation augmented Dickey-Fuller (ADF) tests, and autoregressive distributed lag models following the methodology of Arellano and Bond (1991) and Blundell and Bond (1998) to establish the impact of capital inflows on output growth for the period 2003–2013.

We find no significant role for financial costs in the determination of the RER in the integration process of these countries. The evidence supports a positive influence of external capital inflows, and in particular European structural funds, on the determination of RER. This positive influence also extends to non-tradable goods and public investments.

In order to promote medium-long run sustainability, Central and Eastern European countries should carefully apply European funds in a way that does not bring about higher internal prices, or, if possible, control the nominal exchange rate in accordance. They must invest more in the higher qualification of human resources, research and development, innovation, entrepreneurship and industrial clusters, in view of the development of the tradable sector.

It is the first chapter that analyses the presence of DD originated by European structural funds and external inflows of funds for this group of countries.

This paper aims to analyze the impact of the adoption of ISO 14001 and ISO 9001 on the performance of Portuguese companies. The sample includes the companies listed on Euronext Lisbon, with economic, financial and specific information – the specific being environmental information and quality information – for the period between 2015 and 2019, which corresponds to the post-Troika period when some economic growth started to be witnessed. The specific information of each area is translated into the environmental certification by the ISO 14001 standard, the quality certification by the ISO 9001 standard, and sustainability reports.

To achieve this aim, four variables were used as a measure of the companies' performance, Return on Assets (ROA), Return on Equity (ROE); Tobin's Q and EBITDA Margin. With this data, different panel models were tested to validate if ISO 9001 and ISO 14001 certifications impact Portuguese listed companies performance. Specifically, the authors have used the Generalized Method of Moments, GMM-System, an estimation method proposed by Arellano and Bover (1995) and Blundell and Bond (1998).

The results show that, in general, the environment and quality variables fail to explain the dependent variables, that is, ISO certifications do not provide positive or negative variations in the performance of companies, suggesting that they are not yet as much for civil society, as well as for current or potential shareholders. When used as an independent variable, certification according to the ISO 14001 or 9001 standards, negative and significant oscillations were verified in the dependent variable, MgEBITDA, suggesting that only for managers this variable is determinant, but with a negative impact, given the high costs, it entails without pressure from other stakeholders.

This study is the first to analyze the impact of the adoption of ISO 14001 and ISO 9001 on Portuguese companies' performance. This empirical study aims to show all investors, managers, regulators and civil society itself the long path that still needs to be taken toward sustainability.

This paper aims to analyze the determinants of Portuguese energy companies' performance.

To achieve our objective, we have used data from 457 Portuguese energy companies, in the period between 2011 and 2018. Three dependent variables were tested using panel data, through the generalized method of moments (GMM) estimation method.

The results point out that the determinants of companies' performance change according to how different stakeholders appreciate corporate performance. In general, shareholders are concerned with maintaining their levels of profitability over time as well as with the company's market image. Managers are centered on maintaining solid margins on EBITDA through good management of cash flow, leverage and current assets. For the rest of the stakeholders, including global society, debt and investments in tangible fixed assets reduce profitability while investments in immaterial assets help to create value and performance for energy companies.

As far as the authors are aware, this is the first time that a study has been carried out in the Portuguese energy sector using the GMM-system model for three different stakeholders' views of corporate performance determinants.

ISO 9001 certification is nowadays considered to be one of the most effective tools that can be adopted for guiding the management of Quality Systems. The stunning growth observed by these standards all over the world confirms a strong polarization of enterprises' interest in this practice. Owing to the wide incidence of this phenomenon, a deep investigation of ISO 9001 diffusion over time is of mandatory importance. The research here reported covers the development of statistical models in order to characterize the ISO 9001 certification evolution on a country basis, as well as worldwide.

Based on the pioneering results obtained by Saraiva and Duarte, an attempt is now made to: identify clusters of countries, according to their ISO 9001 evolution patterns; characterize the worldwide ISO 9001 certification evolution; identify which are the main evolution perspectives for ISO 9001 diffusion; identify significant variables that may influence ISO 9001 quality management systems diffusion; develop mathematical models in order to characterize the ISO 9001 certification evolution on a country‐by‐country basis.

The research carried out allowed one to analyze the worldwide evolution of ISO 9001 certification and suggest new prediction models for the diffusion of quality management systems certification at different geographical realities.

This paper covers the development of statistical models in order to characterize the ISO 9001 certification evolution on a country basis, as well as worldwide.

This paper aims to understand whether Portugal, being a relatively peripheral country – in political, economic and military terms – of Southwest Europe, was recently a target of hybrid threats. The prevalence of a specific type of threat was found. Thus, this paper analyses the non-kinetic hybrid threats in Portugal, in a temporary hiatus of two years (2017-2018).

This study has two parts: a conceptual analysis of hybrid threats created by us and, based on the typology previously presented, an analysis of the hybrid threats in Portugal between 2017 and 2018. The first part relied on source analysis, as the result of a desk review methodology, supported by monographs, declassified official documents and reports. The second part is also the result of source analysis, but more extensive. In addition to the desk review methodology, the study included semi-structured interviews with different stakeholders from the Portuguese security and armed forces, who asked not to be quoted. Media content analysis was also carried out – for trends and fact-check – mostly for the events related to the “narratives led operations” (for propaganda, misinformation, counter-information and strategic leaks).

To date, Portugal – compared with other European states – has not been a significant target for hybrid threats. It is diluted in the Portuguese geopolitical dimension. Nevertheless, not escaping what is happening in Europe, it has also been the target of non-kinetic hybrid threats, especially in cyberspace. In the field of so-called “narrative-driven operations”, there have been some occurrences – whether related to fake news, far-right movements or strategic leaks. In addition, cyberattacks from foreign groups for information and data gathering have increased in recent years, making governmental and private critical infrastructures more vulnerable.

One of the characteristics of hybrid threats is their difficult identification. Therefore, information is scarce, which has complicated the research, leading us to assume, in many cases, speculation about the threat. It should also be taken into account that, in the case of cyberspace, until 2018, 90% of the occurrences were not reported, and the study has dealt with only official numbers.

It is not a policy paper. Although it neither points out national vulnerabilities to this type of threat nor makes procedural recommendations or considerations, it is fundamental in identifying the peculiarity of hybrid threats in a democratic state.

This chapter explores the origins, development, and organization of the main Portuguese capitalist groups throughout the fascist dictatorship, the Carnation Revolution, and the neoliberal European integration until the onset of the financial crisis of 2008. The Portuguese experience confirms that, far from the usual neoliberal view that presents the process of accumulation and concentration of capital as the result of fair market mechanisms, large capitalist groups emerge as a combination of three factors: privileged access to finance, State protection, and family inheritance. Furthermore, it is argued that, if capital is considered as embodiment of power relations and not as factor of production, the link between concentration/accumulation of capital and economic growth is appropriately lost. Concentration strategies can have a detrimental effect on the economy. In Portugal, the dominance of these large economic groups contributed to the development of a rentist economic structure that was contrary to the goals of productive and economic development.

In the macroeconomic environment of the Iberian Peninsula, this paper aims to examine the influence of corporate governance characteristics on corporate sustainability performance. The purpose of this paper is to address corporate practices while determining which corporate governance characteristics can improve corporate sustainability, considering, for this purpose, three dimensions of sustainability: economic, environmental and social.

This sample comprises 99 non-financial companies of the Iberian Peninsula, during the 2013–2017 period. The authors have used the panel data methodology, specifically the generalized method of moments (GMM) estimation method proposed by Arellano and Bover (1995) and Blundell and Bond (1998) to test the hypotheses formulated.

The results obtained have shown that corporate sustainability performance is affected differently depending on the sustainability dimension that is considered. Specifically, the economic dimension is determined by public debt, the board size, board diversity and the existence of an audit committee. Regarding the environmental dimension, the board size and the presence of the audit committee, as well the corporate social responsibility committee, are the most important determinants. Finally, the social dimension was influenced by the board size, audit committee and the control variable of capital structure, which means that in this dimension, the sources of financing used by the company also help in determining its levels of social concern.

To the best of the authors’ knowledge, this is the first time that a study has been carried out in the Iberian Peninsula on the corporate sustainability using GMM-system model for three dimensions of sustainability. Corporate sustainability depends on external and internal factors of companies. Therefore, regulators and managers should realize that they will have to be more effective in their statements.
