Preschool teachers’ ideas about practices to promote peer relations: Using Q methodology to determine viewpoints
An internationally accepted definition of early childhood inclusion includes the right to achieve a sense of belonging and membership, positive social relationships, and friendships. Although Portuguese preschool curriculum guidelines value childchild interactions as an outcome by itself and as means to achieving other development and learning outcomes it does not explicitly mention social participation indicators. Additionally, information is lacking on Portuguese preschool teachers’ beliefs, priorities, and practices specifically related to the support of peer relations. This study was developed in the scope of the project Enhancing peer relationships: Preschool teachers' ideas and practices. One of its goals is to understand Portuguese preschool teacher’s ideas about what is important in supporting peer interactions, relationships, and group membership, for children with
and without disabilities. To pursue this goal Q methodology was applied. We developed a Q sample consisting of 74 items that reflect a range of possible interventions targeted at enhancing social inclusion and peer interactions and relationships. The P sample was composed by 43 preschool teachers and their individual Q sorts were subjected to principal components analyses (PCA) followed by varimax rotation. A seven-component solution, explaining 55.5% of the variance, was considered the starting point for the decision-making process on the number of components to be considered as the best solution. Both statistical and conceptual criteria are being used to determine the final number of viewpoints. This presentation describes this decision-making process and the results will be discussed according to their implications for the global project.info:eu-repo/semantics/publishedVersio

The impact of COVID-19 confinement measures in the Air Quality in an urban-industrial zone in Portugal
Comunicação oral apresentada em 25th International Clean Air and Environment Conference CASANZ 2021, 17-21 de maio 2021, onlineThis work aims to evaluate the temporal evolution of the concentrations of
pollutants PM10, NO2 and O3, from 2001 to 2020, and to evaluate the impact
of the COVID-19 pandemic on the levels of these atmospheric pollutants, in
an urban-industrial zone (Paio Pires-Seixal, Portugal). The results showed
that a significant improvement in air quality resulted from the large restriction
of anthropogenic activities that occurred due to the pandemic, namely the
March-May 2020 lockdown. The mean concentrations of PM10, NO2 and O3
in 2020 were compared with the average concentrations measured from 2014
to 2019. The most expressive reduction in NO2 (-43.9%, p=0.000) was found
in April 2020, when a very expressive PM10 reduction was also registered (-
40.0%, p=0.000) and significant reductions of both pollutants were found in
the months thereafter.N/

Citizens’ perception on air quality in Portugal: how concern motivates awareness
This study aimed to understand the knowledge of Portuguese citizens about air quality and the extent to which the concerns about specific environmental problems can motivate their acquaintance of information. Moreover, this study also allowed to understand which information about air quality needs further dissemination to provide the citizens with all the available tools and the correct knowledge. For this, a national online survey about air quality perception was conducted, where 1131 answers were obtained and two different populations were compared: the general population and a sub-population from an urban-industrial area of Lisbon metropolitan area that had experienced frequent air pollution events in the past. Air pollution was considered the environmental topic of higher concern among this sub-population (61.4%), while in the general population it ranked thirdly (27.4%). Generally, the sub-population showed higher knowledge about air quality than the general population, with 61% being able to identify at least one air pollutant. The perception of the local air quality was also very different between populations, with 61% of the sub-population considering it poor or very poor, while only 14% of the general population had the same perception, which highlights the different levels of concern between populations. A weak knowledge about air pollutants (50% of the general population could not identify any air pollutant) and an erroneous perception of the contribution of the different pollution sources to air quality levels were found. More than 50% of the respondents of both populations were considered to not have enough information regarding the air quality in their area of residence, with the national air quality database being unknown to almost everyone. Overall, strong efforts should be made to increase the awareness about the importance of air quality, which may promote a higher acceptance of the implementation of future actions to improve air quality.info:eu-repo/semantics/publishedVersio

Distribution-Based Categorization of Classifier Transfer Learning
Transfer Learning (TL) aims to transfer knowledge acquired in one problem,
the source problem, onto another problem, the target problem, dispensing with
the bottom-up construction of the target model. Due to its relevance, TL has
gained significant interest in the Machine Learning community since it paves
the way to devise intelligent learning models that can easily be tailored to
many different applications. As it is natural in a fast evolving area, a wide
variety of TL methods, settings and nomenclature have been proposed so far.
However, a wide range of works have been reporting different names for the same
concepts. This concept and terminology mixture contribute however to obscure
the TL field, hindering its proper consideration. In this paper we present a
review of the literature on the majority of classification TL methods, and also
a distribution-based categorization of TL with a common nomenclature suitable
to classification problems. Under this perspective three main TL categories are
presented, discussed and illustrated with examples
