- Source apportionment of PM2.5 before and after COVID-19 lockdown in an urban-industrial area of the Lisbon metropolitan area, PortugalPublication . Gamelas ou Carla A. Gamelas, Carla; Canha, Nuno; Vicente, Ana; Silva, Anabela; Borges, Sónia; Alves, Célia; Kertesz, Zsofia; Almeida, Susana MartaThe lockdowns held due to the COVID-19 pandemic conducted to changes in air quality. This study aimed to understand the variability of PM2.5 levels and composition in an urban-industrial area of the Lisbon Metropolitan Area and to identify the contribution of the different sources. The composition of PM2.5 was assessed for 24 elements (by PIXE), secondary inorganic ions and black carbon. The PM2.5 mean concentration for the period (December 2019 to November 2020) was 13 ± 11 μg.m−3. The most abundant species in PM2.5 were BC (19.9%), SO42− (15.4%), NO3− (11.6%) and NH4+ (5.3%). The impact of the restrictions imposed by the COVID-19 pandemic on the PM levels was found by comparison with the previous six years. The concentrations of all the PM2.5 components, except Al, Ba, Ca, Si and SO42−, were significantly higher in the winter/pre-confinement than in post-confinement period. A total of seven sources were identified by Positive Matrix Factorisation (PMF): soil, secondary sulphate, fuel-oil combustion, sea, vehicle non-exhaust, vehicle exhaust, and industry. Sources were greatly influenced by the restrictions imposed by the COVID-19 pandemic, with vehicle exhaust showing the sharpest decrease. Secondary sulphate predominated in summer/post-confinement. PM2.5 levels and composition also varied with the types of air mass trajectories.

- The impact of the COVID-19 pandemic on accounting information systems and organizations’ performancePublication . Gomes, Pedro; Silva, Anabela; da Silva, Amélia Ferreira; Monteiro, Albertina; Pereira, LilianaThis paper empirically examines the impact of COVID-19 on accounting information systems and organizations' performance. It follows a quantitative approach. For data collection, an online questionnaire was developed and tested. The final version of the questionnaire was applied to the 2556 largest companies in Portugal. The 3 research hypotheses under study were tested with 101 valid answers. The results reveal a high rate of implementation of accounting and performance measurement instruments during the COVID-19 pandemic. Regarding the dynamics of the updates of organizations’ performance measurement systems, the impact of the COVID-19 pandemic was confirmed and described as primarily positive. In turn, the performance of the companies was negatively impacted by the COVID-19 pandemic. This study contributes to a better understanding of the role of accounting and performance instruments in organizations under a high level of organizational uncertainty.
