    This paper shows how, in the period 1990-1996, economic integration between the two Iberian economies has deepened through intra-industry trade. The enquiry was led at the level of the main forty traded products. In this context, several tests have been made. Our analysis combines first the application of the Grubel and Lloyd index of the main forty products and the marginal intra-industry trade of Brulhart, and Brulhart and Elliot. On the basis of these indexes we defined our criterion for the selection of the competitive cluster of Portugal throughout the period. We have also considered the global intra-industry trade, in nominal and real terms, according to the method of Greenaway et al. In econometric terms we have tried to know which is the relation between the intra-industry trade index and the marginal intra-industry trade at the level of the main forty products, the results however were not unequivocal. The same is true as far as concerns the relation between the intra-industry trade index and the net export position at the level of the same products. Despite the fact that some attempts have been inconclusive, knowledge about Iberian trade has developed in a field essential to its upgrading, and the way is open for further research.intra-industry trade; marginal intra-industry trade; competitive cluster; net export position.

    Power-law statistics and stellar rotational velocities in the Pleiades

    In this paper we will show that, the non-gaussian statistics framework based on the Kaniadakis statistics is more appropriate to fit the observed distributions of projected rotational velocity measurements of stars in the Pleiades open cluster. To this end, we compare the results from the κ\kappa and qq-distributions with the Maxwellian.Comment: 13 pages, 3 figure

    This study is part of the JUST COVID-19 (UCP) and YO&JUST (CICS-NOVA) projects, aiming to understand the impact of the covid-19 pandemic on the use of illicit substances by young people with delinquent behaviours. Early onset of substance use in adolescence has been associated with increased delinquency and subsequent criminality, specifically including violent crime, and being at particularly high risk of serious problems later in life (Gordon et al., 2004). As the pandemic progressed, containment measures were implemented. Social distancing to decrease interaction between individuals (Duarte, 2020), the closure of schools and other places that provided crowding of the population (Schmidt, 2020), as well as the general isolation caused in young people various stressors such as fear of being infected, distress, loneliness, anxiety and depression (Scalia et al., 2020). These variables may have caused changes in the contexts and patterns of illicit substance use. To understand such changes several professionals who work with young people with deviant behaviours were interviewed. In this poster, we present the study and its main results.info:eu-repo/semantics/publishedVersio
