Leveraging personality as a proxy of perceived transparency in hierarchical vis...
Alves, T.; Dias, C.; Gonçalves, D.; Gama, S.Understanding which factors affect information visualization transparency continues to be one of the most relevant challenges in current research, especially since trust models how users build on the knowledge and use it. This work extends the current body of research by studying the user’s subjective evaluation of the visualization transparency of hierarchical charts through the clarity, coverage, and look and...
Preliminary results on the effect of 1-naphthaleneacetic acid on restoring ‘Roc...
Dias, C.; Rodrigues, A.C.; Vasconcelos, M.W.; Ferrante, A.; Pintado, M.Loss of ripening capacity is still a major problem associated with the use of 1-methylcyclopropene (1-MCP), despite its benefit in preserving climacteric fruit under long-term cold storage, specially, in controlled atmosphere. Several strategies have been tested to overcome this problem, namely the use of phytohormones (e.g., ethylene). In this study, ‘Rocha’ pear treated with 1-MCP was after storage exposed to...
New dynamics of e-commerce on the retail industry: Analysis of the purchase pro...
Gonçalves, R.; Dias, C.; Pereira, L.; Lopes da Costa, R.; Dias, Á.; Vinhas da Silva, R.The technology-mediated environment promoted the creation of new dynamics in the retail sector. To understand how the emergence of e-commerce has impacted the retail sector, this study analysed two distinct product typologies: fashion and electronics. Among the various conclusions of this work, we highlight a clear resistance to the emergence of e-commerce, even though a considerable part of the sample declares...
The influence of remuneration structure on earnings management
Paiva, I.; Carvalho, L. C.; Dias, C.This study draws on agency theory, evaluates the effect of remuneration structures of board members on earnings management, proxied by discretionary accruals. To achieve the objective, this study uses a multiple regression model and a hand-collected dataset of Portuguese listed firms from 2015 to 2019. This study suggests that fixed board remuneration is associated with lower levels of earnings management, as o...

Intensity and safety of community-based physical activities for people with COPD
Rebelo, P.; Santos, E. S.; Rodrigues, G.; Grave, A. S.; Dias, C.; Oliveira, A. C.; Moura, M. J.; Rijo, A. S.; Brooks, D.; Marques, A.Background: long-term maintenance of the benefits obtained with pulmonary rehabilitation (PR) in people with COPD is of upmost importance, yet highly challenging. Integrating these people in community-based physical activities (PAs), after PR, can be a promising strategy to maintain achieved benefits. Nevertheless, to confidently advise people with COPD to enrol these community-based PAs, clinicians must ensure...
ß-Farnesene Exogenous Application as a Novel Damage Induction Model to Fast Exp...
Dias, C.; Amaro, A.; Fonseca, Alexandre; Ferrante, A.; Silvestre, Armando; Rocha, Sílvia M.; Isidoro, N.; Pintado, M.Since the prohibition of diphenylamine, replacement strategies have been needed for long-term disorder prevention, namely superficial scald (SC), in fruit. However, as this disorder only appears after months under cold storage, the assessment of effective strategies to prevent this disorder requires long periods. To tackle this challenge, we report in this paper a rapid and reliable system to induce symptoms, s...
Impact of pulmonary rehabilitation on the social support of people with COPD
Almeida, S.; Rebelo, P.; Rodrigues, G.; Samuel, E.; Monteiro, C.; Grave, A.; Dias, C.; Santos, C.; Simões, A.; Rodrigues, C.; Marques, S.Social support improves general health (e.g., reduces hospitalisations and exacerbations) and well-being of people with COPD, but it has shown to be low in this population. Pulmonary rehabilitation (PR) has potential to improve social support of people with COPD, however, this needs to be investigated. This study explored the impacts of PR on the social support of people with COPD. An observational study was co...
Functional impairment in people with interstitial lung diseases: is one measure...
Dias, C.; Machado, A.; Paixão, C.; Mendes, M. A.; Ferreira, P. G.; Marques, A.Introduction: Interstitial lung diseases (ILD) comprehend a large group of lung diseases that include disease settings associated with sustained progression and leading to respiratory failure, decreased functional status and premature death. Functional status can be defined as an individual’s ability to perform normal daily activities required to meet basic needs, fulfill usual roles and maintain health and wel...
Cut-off points of the 1-minute sit-to-stand test to detect functional impairmen...
Dias, C.; Machado, A.; Mendes, M.; Ferreira, D.; Martins, V.; Simão, P.; Marques, A.Introduction: Functional status is a key outcome in people with chronic obstructive pulmonary disease (COPD) and can be defined as an individual’s ability to perform normal daily activities required to meet basic needs, fulfill usual roles, and maintain health and well-being. The 1-minute sit-to-stand test (1-min STS) is a wellestablished measure to assess functional status in people with COPD that can be used ...
