Wise leaders fostering employees’ speaking up behaviors: Developing and validat...
Rego, A.; Meyer, M.; Reis Júnior, D.; Pina e Cunha, M.Practical wisdom, an essential component of leadership, has been approached mainly from a theoretical perspective. While there are barely any empirical studies on leaders’ practical wisdom, quantitative ones are even rarer, and no valid measure of a leader’s practical wisdom exists. Thus, our understanding of whether and how wise leaders influence their followers is limited. Inspired by Thomas Aquinas’ ideas on...
How leaders ‘Strength of Heart’ and ‘Strength of Will’ enhance team performance
Rego, A.; Simpson, A. V.; Pina e Cunha, M.; Silard, A.; Oliveira, E. A. da S.; Mamedio, D. F.We investigate the influence of leaders’ dispositional compassion on team development and performance through two studies. In the first multi-source study (n = 154 team leaders), leaders’ dispositional compassion is found to be associated with improved team performance through the adoption of helping behaviors aimed at developing team capabilities. This relationship is moderated by leaders’ perseverance, sugges...
From “leadership” to “leading”: power relations, polyarchy and projects
Clegg, S.; Simpson, A. V.; Cunha, M. P.; Rego, A.In this chapter, we discuss the coevolution of leadership and power, pivoting to a consideration of leading in a digitally enabled organizational democracy. We start by providing sense-making of past theorising, discussing the rational mode of organizing (the default mode of organizing in bureaucracies), which as first suggested by Weber, represents a mode of “power over”. Next, we discuss this and other variet...
How knowledge-based dynamic capabilities relate to firm performance: The mediat...
Hernández-Linares, R.; López-Fernández, M. C.; García-Piqueres, G.; Cunha, M. P. e.; Rego, A.To examine how knowledge-based dynamic capabilities relate to firm performance through the mediating role of entrepreneurial orientation, we analyzed data of a sample of 1047 Portuguese and Spanish small and medium-sized enterprises (SMEs) of all industry sectors. The results reveal that knowledge-based dynamic capabilities are associated with firm performance and that the relationship is partially mediated by ...
Attitudes and HRM decisions toward older workers in Africa: Exploring contradic...
Rego, A.; Vitória, A.; Ribeiro, T.; Ribeiro, L.; Lourenço-Gil, R.; Leal, S.; Cunha, M. P. e.We explored the attitudes toward older workers of African versus Portuguese managers, and how these managers make HRM decisions in scenarios involving younger versus older workers. To make cultural, social, and institutional explanations more robust, we also included two samples of students attending Portuguese universities: one sample comprising African students, the other comprising Portuguese ones. The main ...
Seasonal variation of chub mackerel (Scomber colias) selenium and vitamin B12 c...
Rego, A.; Coelho, I.; Motta, C.; Cardoso, C.; Gomes-Bispo, A.; Afonso, C.; Prates, J.A.M.; Bandarra, N.M.; Silva, J.A.L.; Castanheira, I.Chub mackerel (Scomber colias), an underutilised fish species, has been identified as an excellent source of selenium and vitamin B12, which may prevent and delay cognitive decline and dementia. Given these nutrients’ contents seasonal variability, a complete monthly sampling, involving a specifically adjusted methodology for the determination of vitamin B12 (LC-MS/MS) and its main vitamers and a sensitive anal...
Seasonality as experienced in the market and the resulting variation in the ami...
Motta, C.; Rego, A.; Cardoso, C.; Coelho, I.; Gomes-Bispo, A.; Afonso, C.; Prates, J.A.M.; Castanheira, I.; Bandarra, N.Chub mackerel (Scomber colias) is an underutilised fish species, abundant in the Atlantic Ocean. Its amino acid profile and elemental composition are still insufficiently studied. Accordingly, these aspects were studied on a monthly basis. The most abundant essential amino acids, lysine and leucine, had contents ranging from 1270 ± 40 mg/100 g in August to 1820 ± 96 mg/100 g in November and from 1210 ± 36 mg/10...
Mackerel seasonality effect on Se content
Rego, A.; Ventura, M.; Gueifão, S.; Coelho, I.; Cardoso, C.; Afonso, C.; Bandarra, N.; Castanheira, I.Selenium is an essential micronutrient that can become toxic when ingested in high concentrations The human being can obtain Se through the consumption of food, dietary supplements, water and exposure to ambient air The food source is the most abundant and the main contributor to the daily intake of Se in Fish is one of the best sources of Se, and the Portuguese Mackerel is one of the most important and abundan...
Diversity of bacterial biosynthetic genes in maritime antarctica
Rego, A.; Sousa, A.G.G.; Santos, J.P.; Pascoal, F.; Canário, J.; Leão, P.N.; Magalhães, C.Bacterial natural products (NPs) are still a major source of new drug leads. Polyketides (PKs) and non-ribosomal peptides (NRP) are two pharmaceutically important families of NPs and recent studies have revealed Antarctica to harbor endemic polyketide synthase (PKS) and non-ribosomal peptide synthetase (NRPS) genes, likely to be involved in the production of novel metabolites. Despite this, the diversity of sec...
The Extremophile Endolithella mcmurdoensis gen. et sp. nov. (Trebouxiophyceae, ...
Martins, T.P.; Ramos, V.; Hentschke, G.S.; Castelo-Branco, R.; Rego, A.; Monteiro, M.; Brito, Â.; Tamagnini, P.; Cary, S.C.; Vasconcelos, V.The McMurdo Dry Valleys constitute the largest ice‐free region of Antarctica and one of the most extreme deserts on Earth. Despite the low temperatures, dry and poor soils and katabatic winds, some microbes are able to take advantage of endolithic microenvironments, inhabiting the pore spaces of soil and constituting photosynthesis‐based communities. We isolated a green microalga, Endolithella mcmurdoensis gen....
