This study aims to: analyze the impact of ISO 9001 implementation in the organization’s performance in this industry; to study if benefits differ according to the hotels’ rating and if they tend to emerge in long-term; to assess if the most recent version of ISO produces a greater impact than the olde...
A hitchhiker's guide to diffusion tensor imaging
Soares, José Miguel; Marques, Paulo César Gonçalves; Alves, Victor; Sousa, NunoDiffusion Tensor Imaging (DTI) studies are increasingly popular among clinicians and researchers as they provide unique insights into brain network connectivity. However, in order to optimize the use of DTI, several technical and methodological aspects must be factored in. These include decisions on: acquisition protocol, artifact handling, data quality control, reconstruction algorithm, and visualization appro...
Stress impact on resting state brain networks
Soares, José Miguel; Sampaio, Adriana; Ferreira, Luís Miguel; Santos, Nadine Correia; Marques, Fernanda; Palha, Joana Almeida; Cerqueira, JoãoResting state brain networks (RSNs) are spatially distributed large-scale networks, evidenced by resting state functional magnetic resonance imaging (fMRI) studies. Importantly, RSNs are implicated in several relevant brain functions and present abnormal functional patterns in many neuropsychiatric disorders, for which stress exposure is an established risk factor. Yet, so far, little is known about the effect ...
Posterior cortical atrophy and Alzheimer’s disease : a meta-analytic review of ...
Alves, Jorge; Soares, José Miguel; Sampaio, Adriana; Gonçalves, Óscar F.This paper presents the first systematic review and meta-analysis of neuropsychological and brain morphometry studies comparing posterior cortical atrophy (PCA) to typical Alzheimer's disease (tAD). Literature searches were conducted for brain morphometry and neuropsychological studies including a PCA and a tAD group. Compared to healthy controls (HC), PCA patients exhibited significant decreases in temporal, o...
Brain correlates of pro-social personality traits : a voxel-based morphometry s...
Coutinho, Joana; Sampaio, Adriana; Ferreira, Miguel; Soares, José Miguel; Óscar F., GonçalvesOf the five personality dimensions described by the Big Five Personality Model (Costa and McCrae 1992), Extraversion and Agreeableness are the traits most commonly associated with a pro-social orientation. In this study we tested whether a pro-social orientation, as expressed in terms of Extraversion and Agreeableness, is associated with a specific grey matter phenotype. Fifty-two healthy participants underwent...
