Respect and sympathy in Portuguese preschoolers and middle-school children
Costa Martins, Mariana; Cardoso, Evlyne Martins; Pires, E.; Fernandes, M.; Fernandes, C.; Malti, Tina; Veríssimo, ManuelaAbstract: Recent research has revealed theorical and empirical links between respect and socioemotional outcomes such as moral emotions and prosociality, as well as negative associations with aggression. The ability to sympathize, feel concern, and be aware of other’s states has also been hypothesized to influence how children conceptualize respect and evaluate behaviors as worthy of respect. The development of...
The effect of proximal personality traits on entrepreneurial intention among hi...
Brás, G. R.; Daniel, A.; Fernandes, C.Purpose According to the literature, general personality traits are less strongly related to the creation of new ventures than specific/proximal personality traits. Therefore, this study aims to understand the different proximal personalities that influence the entrepreneurial intention to start a new venture and the relationship between them. Design/methodology/approach Data were gathered through a self-admini...
Validity of central pain processing biomarkers for predicting the occurrence of...
Carrillo‑de‑la‑Peña, M. T.; Fernandes, C.; Castro, Catarina; Medeiros, R.Despite recent improvements in cancer detection and survival rates, managing cancer-related pain remains a significant challenge. Compared to neuropathic and inflammatory pain conditions, cancer pain mechanisms are poorly understood, despite pain being one of the most feared symptoms by cancer patients and significantly impairing their quality of life, daily activities, and social interactions. The objective of...
Challenge and conceptual solution for young football players in Portugal
Rodrigues, P.; Fernandes, C.; Teixeira, F.; Tebús, J.; Azevedo, J.; Pawlak, M.; Khan, M.; Pereira, Fernando A.The challenge titled "Footballer's Journey Upgrade" aims to improve the living conditions and safety of young football players arriving in Portugal to play professionally, who face financial and social instability. The proposed solution involves the development of a computer/mobile app that functions as a support platform for these players. This platform will offer job proposals from support groups and legal in...
The impact of entrepreneurial ecosystems on digital transformation: A meso leve...
Guimarães, J.; Fernandes, C.; Veiga, P.; Lobo, Carla AzevedoDocumento aceite; aguarda publicação; This work aims to study the impact of meso-level variables of entrepreneurial ecosystems (EEs) on digital transformation. Statistical analysis was used to evaluate the research hypotheses, based on multiple linear regression, with a sample of 172 organisations. The results show that actors from the meso dimension of EEs positively impact digital transformation through knowl...
Advanced polymer simulation and processing Volume II
Fernandes, C.; Faroughi, Salah Aldin; Ferrás, Luís Jorge Lima; Afonso, Alexandre Miguel Prior[Excerpt] Polymer-processing techniques are of the utmost importance for producing polymeric parts. They must produce parts with the desired qualities, which are usually related to mechanical performance, dimensional conformity, and appearance. Aiming to maximize the overall efficiency of the polymer-processing techniques, advanced modeling codes along with experimental measurements are needed to simulate and o...
A primer on CFD-DEM for polymer-filled suspensions
Fernandes, C.; Ferrás, Luís Jorge Lima; Afonso, Alexandre Miguel PriorThis work reports on an evaluation of the computational fluid dynamics–discrete element method (CFD-DEM) numerical approach to study the behavior of polymer-filled suspensions in a parallel-plate rheometer. For this purpose, an open-source CFD-DEM solver is used to model the behavior of such suspensions considering different particle volume fractions and different types of fluid rheology. We first validate the ...
Changes on swimming behavior induced by 3,4-methylenedioxypyrovalerone (MDPV) e...
Pérez-Pereira, A.; Carvalho, A.; Castro, B.; Carrola, J. S.; Fernandes, C.; Tiritan, M.; Ribeiro, C.Background: Synthetic cathinones (SC) are a group of novel illicit psychotropic substances that have been found in the aquatic environment at low concentrations [1] and nonetheless they can impact aquatic invertebrates [2]. SC can pose unwanted diverse adverse effects such as behavioral toxicity to non-target organisms [3]. The 3,4-methylenedioxypyrovalerone (MDPV) is a chiral SC with psychotropic properties si...
In vitro permeability of MDPV across Caco-2 cells for assessment of intestinal ...
Almeida, A. S.; Silva, B.; Remião, F.; Fernandes, C.Background: Synthetic cathinones, such as 3,4-methylenedioxypyrovalerone (MDPV), are widely studied chiral psychoactive substances [1]. Enantioselectivity studies on the toxicokinetic of synthetic cathinones are still scarce [2], namely on their ability to cross the intestinal membrane, which was evaluated only for methylone and pentedrone [3]. To isolate enantiomers for these studies, liquid chromatography (LC...
New 8-hydroxyquinoline derivatives as promising therapeutic approaches targetin...
Marques-Oliveira , R.; Alfenim, A. R.; Soares , P.; Borges , F.; Remião, F.; Fernandes, C.; Silva , R.Background: Alzheimer's disease, Parkinson's disease, and Amyotrophic lateral sclerosis are recognized as the most prevalent neurodegenerative diseases (NDs), presenting a huge burden for society. These diseases share common pathophysiological mechanisms, such oxidative stress, dysfunction in iron metabolism, ferroptosis, and protein misfolding [1-4]. Given their powerful metal chelating and antioxidant propert...
