- Authentic leadership promoting employees' psychological capital and creativityPublication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Pina e Cunha, MiguelTwo hundred and one employees report their psychological capital, as well as their supervisors' authentic leadership. Supervisors describe the employees' creativity. The main findings show that authentic leadership predicts employees' creativity, both directly and through the mediating role of employees' psychological capital. The study empirically validates theoretical arguments that suggest integrating authentic leadership and psychological capital in research, and indicates that both may foster employees' creativity, a crucial resource for helping organizations to face competitive challenges, take advantage of business opportunities, and improve organizational effectiveness.
- Gait Kinematics Analysis of Flatfoot AdultsPublication . Marouvo, Joel; Sousa, Filipa; Fernandes, Orlando; Castro, Maria António; Paszkiel, SzczepanBackground: Foot postural alignment has been associated with altered gait pattern. This study aims to investigate gait kinematic differences in flatfoot subjects’ regarding all lower limb segments compared to neutral foot subjects. Methods: A total of 31 participants were recruited (age: 23.26 yo ± 4.43; height: 1.70 m ± 0.98; weight: 75.14 kg ± 14.94). A total of 15 subjects were integrated into the flatfoot group, and the remaining 16 were placed in the neutral foot group. All of the particpants were screened using the Navicular Drop Test and Resting Calcaneal Stance Position test to characterize each group, and results were submitted to gait analysis using a MOCAP system. Results: Significant kinematic differences between groups were found for the ankle joint dorsiflexion, abduction, and internal and external rotation (p < 0.05). Additionally, significant differences were found for the knee flexion, extension, abduction, and external rotation peak values (p < 0.001). Significant differences were also found for the hip flexion, extension, external rotation, pelvis rotation values (p < 0.02). Several amplitude differences were found concerning ankle abduction/adduction, knee flexion/extension and abduction/adduction, hip flexion/extension and rotation, and pelvis rotation (p < 0.01). Conclusion: Flatfooted subjects showed kinematic changes in their gait patterns. The impact on this condition on locomotion biomechanical aspects is clinically essential, and 3D gait biomechanical analysis use could be advantageous in the early detection of health impairments related to foot posture.
- Optimism predicting employees' creativity: The mediating role of positive affect and the positivity ratioPublication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Pina e Cunha, MiguelWe examine how optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio (the ratio between the frequency of positive and negative affective states). Five hundred and ninety five employees reported their positive and negative affect, as well as their optimism. Their creativity was reported by supervisors. The main findings are the following: (1) optimism predicts creativity both directly and through the mediating role of positive affect and the positivity ratio; (2) the relationship between the positivity ratio and creativity is curvilinear, in such a way that an "excessive" ratio is detrimental to creativity. The findings stress the relevance of optimism both for individuals and organizations, and suggest that examining positivity ratios is fruitful in the creativity domain, as it has been in other domains, and that negative affect should not be viewed simply as an obstacle when studying employees' creativity.
- Retail employees' self-efficacy and hope predicting their positive affect and creativityPublication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Cunha, Miguel Pina E.The study shows how retail employees’ self-efficacy and hope predict their creativity, both directly and through the mediating role of positive affect. Five hundred and seven retail employees reported their hope, self-efficacy, and positive affect, their supervisors reporting their creativity. Three main findings are: (1) hope and self-efficacy predict creativity; (2) positive affect also predicts creativity; (3) positive affect partially mediates the relationship between both dimensions of positive psychological capital (self-efficacy and hope), and creativity. The study suggests that retail organizations may foster employees’ creativity by encouraging conditions that cultivate employees’ hope and selfefficacy, as well as their positive affect.
