CRECER EN UNA CRISIS INTERMINABLE: TRANSICIONES Y ASPIRACIONES DE JÓVENES EN PORTUGAL

Over the past two decades, young people have faced increasing social and economic instability. Before the world had fully recovered from the tremendous effects of the global financial crisis of 2007-08, it was hit by the COVID-19 pandemic. With the effects of such crises being felt unevenly, what are the implications of these challenging times for the educational and professional aspirations of young people in vulnerable situations? To investigate, this paper draws on the lived experiences of young people (15-24 years old) in Portugal, ranging from early leavers from education and training to students currently enrolled both in mainstream schools and other educational institutions. The qualitative data used are drawn from two distinct research projects. By combining these two data sets, we have expanded our understanding of the impact of these crises on young people’s aspirations and educational trajectories. The findings indicate that, within the framework of successive economic, political and social crises, pre-existing situations of social vulnerability tend to intensify and may lead to disengagement from school, and even dropping out. Often, the need to help support their families leads many young people to enter a competitive and highly precarious labour market. This article renders visible the impact that structural and systemic factors – intrinsically linked to issues of inequality and social injustice – can have on the educational aspirations and trajectories of young people in a society in which ‘being in crisis’ has somehow become the new norm.En las dos últimas décadas, los jóvenes se han enfrentado a una creciente inestabilidad social y económica. Antes de que el mundo se haya recuperado completamente de los tremendos efectos de la crisis financiera mundial de 2007-08, se vio afectado por la pandemia del COVID-19. Dado que los efectos de este tipo de crisis se dejan sentir de forma desigual, ¿cuáles son las implicaciones de estos tiempos difíciles para las aspiraciones educativas y profesionales de los jóvenes en situación de vulnerabilidad? Para investigarlo, este artículo se basa en las experiencias vividas por jóvenes (15-24 años) en Portugal, desde los que abandonan prematuramente la educación y la formación hasta los estudiantes actualmente matriculados tanto en escuelas ordinarias como en otras instituciones educativas. Los datos cualitativos utilizados proceden de dos proyectos de investigación distintos. Al combinar estos dos conjuntos de datos, hemos ampliado nuestra comprensión del impacto de estas crisis en las aspiraciones y trayectorias educativas de los jóvenes. Los resultados indican que, en el marco de sucesivas crisis económicas, políticas y sociales, las situaciones preexistentes de vulnerabilidad social tienden a intensificarse y pueden conducir a la desvinculación de la escuela, e incluso al abandono escolar. A menudo, la necesidad de ayudar a mantener a sus familias lleva a muchos jóvenes a entrar en un mercado laboral competitivo y muy precario. Este artículo hace visible el impacto que los factores estructurales y sistémicos -intrínsecamente ligados a cuestiones de desigualdad e injusticia social- pueden tener en las aspiraciones y trayectorias educativas de los jóvenes en una sociedad en la que “estar en crisis” se ha convertido en la nueva norma

Inheritance of resistance to Puccinia psidii G. Winter in a eucalyptus interspecific hybrid progeny evaluated under conditions of natural infection

A ferrugem, causada pelo fungo Puccinia psidii, é atualmente a mais importante doença do eucalipto. Esta doença está amplamente disseminada pelo Brasil e causa sérios danos em viveiros e plantações. A identificação de germoplasma resistente aliado ao conhecimento da base genética da resistência são os requerimentos primordiais para o sucesso de programas de melhoramento visando à produção de cultivares resistentes. Estudos anteriores sobre a herança da resistência em condições controladas sugerem tanto uma herança monogênica como a participação de pelo menos 2 genes conferindo resistência à doença. O objetivo deste estudo foi avaliar a resistência a P. psidii, em condições de campo em quatorze progênies obtidas a partir de cruzamentos e auto-cruzamentos controlados entre quatro clones híbridos de Eucalyptus grandis Hill ex Maiden x Eucalyptus urophylla ST Blake,que contrastam para a resistência ao fungo. Os resultados indicam que a resistência pode ser explicada por um loco com efeito principal e pelo menos três alelos diferentes, com interações entre os alelos, resultando no fenótipo de resistência ou suscetibilidade. Entretanto, locos com menor efeito devem influenciar a resistência, uma vez que foram observadas variações nas classes de severidade da escala utilizada. Nenhuma diferença na segregação para a resistência foi observada entre cruzamentos recíprocos, sugerindo que não existe influência citoplasmática no controle deste caráter.Rust caused by the fungus Puccinia psidii is currently the most important disease of eucalyptus. It is widely disseminated in Brazil, and causes serious damage in nurseries and plantation areas. The identification of resistant germplasm along with knowledge of the genetic basis of resistance heredity are the first requirements for the success of breeding programs aiming to develop resistant varieties. Earlier studies carried out under controlled conditions suggested a monogenic control as well as the participation of at least two genes promoting resistance to rust. The goal of this study was to evaluate the resistance to P. psidii under field conditions in fourteen progenies from controlled crosses and self-crosses among four hybrid clones of Eucalyptus grandis Hill ex Maiden x Eucalyptus urophylla ST Blake that contrast for resistance to the fungus. Results indicated that resistance could be explained by one locus with main effects and at least three different alleles. However, loci with minor effects may influence the resistance, since variation on severity classes was observed. Differences in segregation of resistance between reciprocal crosses were not observed, indicating absence of cytoplasmic effects.Votorantim Celulose e PapelConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Correlação entre ensaios com câmara termográfica e resistógrafo na avaliação da integridade de vigas antigas de madeira

Este trabalho de investigação pretende dar um contributo no campo das técnicas não destrutivas de inspecção e de diagnóstico de vigas antigas de madeira. Para o efeito, correlacionou-se os resultados obtidos através do uso do resistógrafo e da termografia no estudo de uma viga recolhida num edifício de habitação unifamiliar que foi sujeito a um processo de remodelação. Verificou-se que poderá haver uma cerca correlação entre ensaios. Contudo, também se recomenda a realização de um número mais expressivo de ensaios de amostras para ser possível apresentar uma conclusão mais fidedigna. A relevância desta possível correlação prende-se com o facto de poder haver uma alternância na realização destes ensaios consoante os condicionalismos do cenário de obra

Fermentation performance and nutritional assessment of physically processed lentil and green pea flour

BACKGROUND A significant amount of nutrients, including dietary fibers, proteins, minerals, and vitamins are present in legumes, but the presence of anti‐nutritional factors (ANFs) like phytic acid, tannins, and enzyme inhibitors impact the consumption of legume and nutrient availability. In this research, the effect of a physical process (sonication or precooking) and fermentation with Lactobacillus plantarum and Pediococcus acidilactici on ANFs of some legumes was evaluated. RESULTS Total phenolic contents were significantly (p\u3c0.05) reduced for modified and fermented substrates compared to non‐fermented controls. Trypsin inhibitory activity (TIA) was reduced significantly for all substrates except for unsonicated soybean and lentil fermented with L. plantarum and P. acidilactici. When physical processing was done, there was a decrease in TIA for all the substrate. Phytic acid content decreased for physically modified soybean and lentil but not significantly for green pea. Even though there was a decrease in ANFs, there was no significant change in in vitro protein digestibility for all substrates except for unsonicated L. plantarum fermented soybean flour and precooked L. plantarum fermented lentil. Similarly, there was change in amino acid content when physically modified and fermented. CONCLUSION Both modified and unmodified soybean flour, green pea flour, and lentil flour supported the growth of L. plantarum and P. acidilactici. The fermentation of this physically processed legume and pulse flours influenced the non‐nutritive compounds, thereby potentially improving nutritional quality and usage
