Is there an optimal working capital management that minimizes European stock risk?
Coelho, Tiago; Lisboa, Inês; Oliveira, CéliaPurpose: This paper investigates the existence of an optimal point of the cash conversion cycle (CCC) and its components, which minimizes firms’ stock risk.Methodology: This study applies fixed effect models to a sample of firms listed in Euronext exchanges, from 2011 to 2019. Stock risk is proxied by the standard deviation of stock returns. The quadratic function of the CCC and its components (days sales outst...

School and student determinants of reading performance : A multilevel analysis ...
Lopes, João; Oliveira, Célia; Costa, PatríciaReading is crucial for learning, in general. Starting right with reading in primary grades is, therefore, vital for school achievement. The present study aims to test whether students’ factors best predict reading performance than school factors and determine what student and school factors predict reading performance. The study sample includes 4,118 fourth-grade students participating in IEA PIRLS 2016. Three ...
Teacher and school determinants of perceived classroom discipline: a multilevel...
Lopes, João A.; Oliveira, CéliaClassroom discipline is a significant concern in most educational systems and a critical element of an effective learning environment. In this article, we present a multilevel analysis of teachers' perceived classroom discipline (PCD) in Portugal, using data from the TALIS 2013. Portuguese teachers perceived slightly more classroom discipline problems than the mean of OECD countries, with classroom variables ex...
