ArticleIntrinsic connectivity networks from childhood to late adolescence: Effects of age and sex(Elsevier Ltd., 2016-02) Solé Padullés, Cristina; Castro Fornieles, Josefina; Serna, Elena de la, 1978-; Calvo Escalona, Rosa; Baeza, Inmaculada, 1970-; Moya, Jaime; Lázaro García, Luisa; Rosa, Mireia; Bargalló Alabart, Núria; Sugranyes, GiselaThere is limited evidence on the effects of age and sex on intrinsic connectivity of networks underlying cognition during childhood and adolescence. Independent component analysis was conducted in 113 subjects aged 7-18; the default mode, executive control, anterior salience, basal ganglia, language and visuospatial networks were identified. The effect of age was examined with multiple regression, while sex and 'age×sex' interactions were assessed by dividing the sample according to age (7-12 and 13-18 years). As age increased, connectivity in the dorsal and ventral default mode network became more anterior and posterior, respectively, while in the executive control network, connectivity increased within frontoparietal regions. The basal ganglia network showed increased engagement of striatum, thalami and precuneus. The anterior salience network showed greater connectivity in frontal areas and anterior cingulate, and less connectivity of orbitofrontal, middle cingulate and temporoparietal regions. The language network presented increased connectivity of inferior frontal and decreased connectivity within the right middle frontal and left inferior parietal cortices. The visuospatial network showed greater engagement of inferior parietal and frontal cortices. No effect of sex, nor age by sex interactions was observed. These findings provide evidence of strengthening of cortico-cortical and cortico-subcortical networks across childhood and adolescence- ArticleActores y modelos de gobernanza en las Smart cities(Universidad de Almería, 2016-10-01) Tomàs Fornés, Mariona; Cegarra, BlancaEn este trabajo se analizan los actores y modelos de gobernanza que promueven las Smart cities. Los conceptos de sostenibilidad, eficiencia y participación son el núcleo del paradigma de ciudad inteligente. Para configurar la Smart city se introducen nuevas herramientas de gobierno como los partenariados públicoprivados que fomentan la cooperación entre las administraciones locales y el sector energético y tecnológico. ¿Hasta qué punto este tipo de herramientas transforman el modelo de gobernanza urbana? ¿Es la Smart city una oportunidad para la participación ciudadana o, por el contrario, la ocasión para que los intereses privados influyan en las políticas urbanas? El caso de Barcelona entre 2011 y 2015 es un buen ejemplo para explorar la transformación que podría promover este modelo en la gobernanza urbana.
- ArticleFootwear-Related Modulation of Scalp EEG Theta/Alpha Ratio During Walking in Children: An Exploratory Within-Subject Study(American Podiatric Medical Association (APMA), 2026-10-30) Moya Cuenca, Coral; Gijon Noguerón, Gabriel; Reinoso Cobo, Andrés; Pérez Palma, Laura; Chicharro Luna, EstherBackground: Childhood is a critical period for neuromotor development, during which footwear may influence the sensory and mechanical context of walking. This study examined whether footwear condition was associated with changes in scalp-level EEG activity during walking in 37 typically developing children aged 6–7 years. Methods: Participants completed repeated 10 m walking trials under three randomized conditions: barefoot, barefoot-style footwear, and conventional structured footwear. EEG was recorded using a mobile 14-channel Emotiv EPOC X system. The primary outcome was the global Theta/Alpha ratio averaged across scalp electrodes. Results: Footwear condition significantly affected the global Theta/Alpha ratio (F (2,72) = 14.57, p < 0.001). Conventional structured footwear produced higher Theta/Alpha values than both barefoot walking and barefoot-style footwear, whereas no significant differences were found between barefoot and barefoot-style conditions. Mean paired differences were 1.08 for conventional versus barefoot and 0.99 for conventional versus barefoot-style footwear. Similar directional effects were observed across electrode groupings. No significant differences were identified in absolute theta, alpha, or beta power, global Beta/Alpha ratio, or Shannon entropy. Conclusions: Conventional structured footwear was associated with increased scalp-level Theta/Alpha activity during walking in children, suggesting possible footwear-related modulation of attentional or motor-control demands.
