Strategic perspective of error management the role of leadership and an error m...
Oliveira, M.; Santos, E.; Ratten, V.Purpose – Errors are inevitable, resulting from the human condition itself, system failures and the interaction of both. It is essential to know how to deal with their occurrence, managing them. However, the negative tone associated with them makes it difficult for most organizations to talk about mistakes clearly and transparently, for fear of being harmed, preventing their detection, treatment and recovery. C...
Psychological empowerment for the future of work: Evidence from Portugal
Oliveira, M.; Andrade, J.; Ratten, V.; Santos, E.In the competitive global marketplace, it is becoming important for organizations to empower employees for productivity reasons. One of the organizational empowerment models with greater support and consistency in the various studies in which it has been used is Spreitzer's Model of Psychological Empowerment in the Workplace, published in 1995. The model is composed of four dimensions that allow the measurement...

Urinary biomonitoring in firefighters: baseline data of polycyclic aromatic hyd...
Barros, B.; Oliveira, M.; Paiva, M.; Fernandes, A.; Alves, S.; Vaz, J.; Esteves, F.; Slezakova, K.; Alves, M.J.; Madureira, J.; Pereira, M.C.Polycyclic aromatic hydrocarbons (PAHs) are among the most relevant pollutants in the firefighting context and urine the most straightforward and interesting matrix for biomonitoring. Recent studies have found elevated levels of PAH metabolites in firefighters in comparison to the general population. Since Portuguese firefighters are poorly characterized, the aim of this study was to determine the baseline data...
In vitro toxicity assessment of firefighters’ breathable air collected on polyu...
Bessa, M. J.; Teixeira, J.; Delerue-Matos, C.; Sarmento, B; Rodrigues, F.; Oliveira, M.Background: Occupational exposure as a firefighter has been recently classified as carcinogenic to humans (Group 1) by the International Agency for Research on Cancer (IARC) [1]. Polycyclic aromatic hydrocarbons (PAH) are one of the main fire-related pollutants [3], and their presence in the breathable air of firefighters was already demonstrated [4]. However, the toxicity mechanisms involved in such exposures ...
Controlling properties of ceramic formulations for porcelain robocasting
Pires, L.S.O.; Luís, J.; Fernandes, M.H.V.; Oliveira, M.Porcelain pastes (PlotPastes) were formulated to be used on an additive manufacturing (AM) process (material extrusion) process, primarily robocasting (R3D) technique. The material morphological and thermal characteristics were evaluated by scanning electron microscopy (SEM), differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The rheology and the electrical potential of the ceramic partic...
Molecular detection of Aspergillus in respiratory samples collected from patien...
Oliveira, M.; Pinto, M.; Simões, H.; Gomes, J.P.; Veríssimo, C.; Sabino, R.Objective: Aspergillosis diagnosis depends on the detection of Aspergillus in biological samples ─ usually using cultural and immunoenzyme techniques ─ but their sensitivity and specificity varies. We aimed to study the prevalence of Aspergillus in patients at higher risk of chronic pulmonary aspergillosis (i.e., HIV-infected patients and individuals with active or previous tuberculosis), and to determine the p...
O contributo do GO FruitFlyProtect para melhorar a proteção contra a drosófila-...
Figueiredo, E.; Godinho, Maria; Simões, M.; Alexandre, P.; Mendonça, T.; Oliveira, M.; Mateus, C.; Valério, Elsa; Mexia, A.Apresentam-se os resultados obtidos no GO FruitFlyProtect relativos às capturas de Drosophila suzukii em armadilhas (dispositivo e isco), para estimativa do risco ou para captura em massa. Utilizaram-se os dispositivos das marcas Econex, Koppert, Biobest, com o isco respetivo, e garrafa PET e dispositivo “Lasa”, construídos artesanalmente e iscados com composto de vinagre da empresa Mendes & Gonçalves Lda.

Staphylococcus spp. and Lactobacillus sakei Starters with High Level of Inocula...
Dias, I.; Laranjo, M.; Potes, M.E.; Agulheiro-Santos, A.C.; Ricardo-Rodrigues, S.; Fraqueza, M.J.; Oliveira, M.; Elias, M.Paio do Alentejo (PA) is one of the most popular dry-fermented sausages in Portugal. The aim of the present work was to evaluate the effect of a high concentration of starter cultures with an extended fermentation step on the safety and quality of PA. Physicochemical parameters, microbiological parameters, biogenic amines, colour, texture profile, and sensory attributes were assessed. Five starters were selecte...
