Assessing the differences of two vineyards soils’ by NIR spectroscopy and chemo...
Machado, Sandia; Barreiros, Luísa; Graça, António R.; Madeira, Manuel; Páscoa, Ricardo N. M. J.; Segundo, Marcela A.; Lopes, João A.Soil properties influence greatly the status of vine plants which consequently influences the quality of wine. Therefore, in the context of viticulture management, it is extremely important to assess the physical and chemical parameters of vineyards soils. In this study, the soils of two vineyards were analysed by near-infrared (NIR) spectroscopy and established analytical reference procedures. The main objecti...
A data mining tool for untargeted biomarkers analysis: Grapes ripening application
Machado, Sandia; Barreiros, Luisa; Graça, António R.; Páscoa, Ricardo N.M.J.; Segundo, Marcela A.; Lopes, João A.In metabolomics, data generated by untargeted approaches can be very complex due to the typically extensive number of features in raw data (with and without chemical relevance), dependence on raw data preprocessing methods, and lack of selective data mining tools to appropriately interpret these data. Extraction of meaningful information from these data is still a significant challenge in metabolomics. Moreover...
The burnout experience among teachers: a profile analysis
Mota, Ana Isabel; Lopes, João A.; Oliveira, CéliaThe burnout syndrome is a public health problem and is considered a subjective experience, which depends on the interpretation and evaluation individuals make of their work. In the educational context, the causes and consequences of burnout in teachers are multiple. The aim of this study is to explore the profiles of teachers with burnout and teachers without burnout in terms of (i) cognitive appraisal, (ii) pe...
In situ co-amorphization of Olanzapine in the matrix and on the coat of pellets
Costa, Nuno F. da; Azevedo, Raquel F.; Lopes, João A.; Fernandes, Ana I.; Pinto, João F.In situ amorphization is a promising approach, considered in the present work, to enhance the solubility and dissolution rate of olanzapine, while minimizing the exposure of the amorphous material to the stress conditions applied during conventional processing. The production of pellets by extrusion/spheronization and the coating of inert beads were investigated as novel methods to promote the co-amorphization ...
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...
School and student determinants of reading performance: a multilevel analysis w...
Lopes, João A.; 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 ...

Foram selecionados 60 estudos para compor a revisão. Os resultados mostraram que testes comportamentais como o BASC e versões DESSA 1-2-3 e DESSA-mini estão entre os mai...
Trends and issues involving disabilities in higher education
Kauffman, James M; Anastasiou, Dimitris; Felder, Marion; Lopes, João A.; Hallenbeck, Betty A.; Hornby, Garry; Ahrbeck, BerndPeople with disabilities have often been discriminated against in higher education; however, many institutions of higher education find ways of providing access to higher education for those with most forms of disabilities. Progress has been made in providing such access but undoubtedly there is still a need for more disability awareness, anti-stigma, and anti-discrimination training. At the same time higher ed...
Imagining and reimagining the future of special and inclusive education
Kauffman, James M.; Anastasiou, Dimitris; Hornby, Garry; Lopes, João A.; Burke, Mack D.; Felder, Marion; Ahrbeck, Bernd; Wiley, Andrew“Reimagination” is required to create a new vision of education that better serves individuals with disabilities. Imagination is a way of conceiving possibilities and probabilities. The future of special education is imagined within the limits of possibility and probability of “appropriate” education for children with special educational needs and disabilities. Education is reimagined for full inclusion without...
