Moderating effect of work-family conflict on the relationship between perceived...
Sousa, C. de; Viseu, J.; Vincent, P.; Vinagre, H.; Romana, F. A.; Pissarra, J.; Ferreira, J.; Gestoso, C. G.The constant changes observed in the work context resulting from the COVID-19 pandemic brought new challenges to organizations and workers. This study examined the moderating effect of work-family conflict on the relationship between perceived organizational support, job satisfaction, and life satisfaction. The collected sample comprised 476 Portuguese workers, of whom 223 were females (46.8%), and 253 were mal...
Osmotic dehydration of cut apple: mass transfer kinetics and microstructural ch...
Assis, F. R.; Pissarra, J.; Morais, R. M. S. C.; Morais, A. M. M. B.Apple cubes were osmotically dehydrated with 40 degrees Bx sucrose and sorbitol solutions. Light microscopy was used to observe the microstructure of fresh and osmotically dehydrated samples. Peleg's model could fit the experimental data and describe the mass transfer kinetics of water loss (WL) and solid gain (SG). The use the sorbitol as osmotic agent. the increase of temperature and concentration of the solu...
Estruturas e dinâmicas de grupo.
Pissarra, J.; Jesuino, J.C.,A revisão efectuada não será de modo algum exaustiva nem esse era ou poderia ser o seu objectivo. A produção sobre o tema dos grupos e equipas tem crescido em ritmo geométrico e mesmo quando limitada a um quadro conceptual restrito é difícil uma leitura integrativa e muito menos conclusiva. Acresce que o estudo dos grupos tende a atrair a atenção de diversas disciplinas que pelas suas afinidades, convida à dilu...
Learning from Failure: A case study on creative problem solving
Sousa, F.; Monteiro, I.; Pissarra, J.; Walton, A.to learn even from failure. With the goal of increasing efficiency by reducing session time and also due to theoretical considerations, a four-step model was designed, comprising the stages of objective-finding, problem-definition, action-planning and the action itself. Following these adaptations, our research involved an organisation that enabled us to bring managers and volunteers to work on a project. The o...
Cardosins in postembryonic development of cardoon: towards an elucidation of th...
Pereira, Cláudia Sofia; Costa, Diana Soares da; Pereira, Susana; Nogueira, F. de Moura; Albuquerque, P. M.; Teixeira, J.; Faro, C.; Pissarra, J.Summary. Following on from previous work, the temporal and spatial accumulation of the aspartic proteinases (EC 3.4.23) cardosin A and cardosin B during postembryonic seed development of cardoon (Cynara cardunculus) was studied. mRNA and protein analyses of both cardosins suggested that the proteins accumulate during seed maturation, and that cardosin A is later synthesised de novo at the time of radicle emerge...
