Emociones y salud actividades propiciadoras de emociones positivas

Se parte del concepto de emoción positiva, vivida en contextos, cuya experiencia subjetiva, es auto-percibida como bienestar (Seligman & Csikszentmihalyi, 2000), razón por la que se considera aquí como promotora de Salud. Así, este estudio de carácter cualitativo organiza, con una “teoría basada en los datos”, las entrevistas semi-estructuradas, en una muestra intencional de 60 profesores. Los contenidos discursivos obtenidos se sometieron a análisis de contenido, de donde surgió un “árbol de categorías“ con 3 generaciones, alrededor de las actividades que proporcionan emociones positivas. Las actividades identificadas que proporcionan emociones positivas agregan un árbol de 13 categorías, que serán presentadas por orden decreciente de unidades discursivas: “Amor”, “Amigos” “Sentir la Naturaleza”, “Familia”, “Fare Niente”, “Pie Fuera de la Puerta”, “Musicalidad”, “Dormir”, “Lecturas”, “Trabajar en lo que nos gusta”, “Convivir”, “Baño” y finalmente, la categoría “Tener Dinero”. Se concluye que será posible proporcionar el desarrollo de estas actividades en ambiente laboral, para experienciar el bienestar subjetivo

Shintani descent for standard supercharacters of algebra groups

Let $\mathcal{A}(q)$ be a finite-dimensional nilpotent algebra over a finite field $\mathbb{F}_{q}$ with $q$ elements, and let $G(q) = 1+\mathcal{A}(q)$. On the other hand, let $\Bbbk$ denote the algebraic closure of $\mathbb{F}_{q}$, and let $\mathcal{A} = \mathcal{A}(q) \otimes_{\mathbb{F}_{q}} \Bbbk$. Then $G = 1+\mathcal{A}$ is an algebraic group over $\Bbbk$ equipped with an $\mathbb{F}_{q}$-rational structure given by the usual Frobenius map $F:G\to G$, and $G(q)$ can be regarded as the fixed point subgroup $G^{F}$. For every $n \in \mathbb{N}$, the $n$th power $F^{n}:G\to G$ is also a Frobenius map, and $G^{F^{n}}$ identifies with $G(q^{n}) = 1 + \mathcal{A}(q^{n})$. The Frobenius map restricts to a group automorphism $F:G(q^{n})\to G(q^{n})$, and hence it acts on the set of irreducible characters of $G(q^{n})$. Shintani descent provides a method to compare $F$-invariant irreducible characters of $G(q^{n})$ and irreducible characters of $G(q)$. In this paper, we show that it also provides a uniform way of studying supercharacters of $G(q^{n})$ for $n \in \mathbb{N}$. These groups form an inductive system with respect to the inclusion maps $G(q^{m}) \to G(q^{n})$ whenever $m \mid n$, and this fact allows us to study all supercharacter theories simultaneously, to establish connections between them, and to relate them to the algebraic group $G$. Indeed, we show that Shintani descent permits the definition of a certain ``superdual algebra'' which encodes information about the supercharacters of $G(q^{n})$ for $n \in \mathbb{N}$

Experimental investigations on continuous glass-GFRP beams: preliminary nonlinear numerical modelling

This paper describes results of experimental and numerical investigations about the structural behaviour of composite beams made of annealed glass panes and GFRP pultruded profiles. A brief description of flexural tests previously carried out on simply supported glass and glass-GFRP composite beams is first presented. Then, results of flexural tests on two-span glass-GFRP composite beams, bonded with three different structural adhesives, are described in detail. Finally, a preliminary numerical study of the glass-GFRP composite simply supported beams is presented. In this study, two-dimensional finite element models were developed in order to simulate and analyse the serviceability and post-cracking behaviour of those beams. Experimental and numerical results presented in this paper prove the advantages and technical viability of glass-GFRP composite beams

Numerical simulation of transparent glass-GFRP composite beams using smeared crack models

This paper describes results of experimental and numerical investigations about the structural behaviour of composite beams made of annealed glass panes and GFRP pultruded profiles. A brief description of flexural tests previously carried out on glass and glass-GFRP composite beams is first presented. The second part of this paper describes the numerical simulation of a rectangular glass-GFRP composite beam. Two-dimensional finite element (FE) models of the composite beam were developed in order to simulate and analyse their serviceability behaviour (prior to glass breakage) as well as their post-cracking behaviour until the failure. To this end, a multi-fixed smeared crack model was used, and the effects of the following parameters were evaluated: (i) fracture energy of glass and (ii) shear retention factor. Experimental and numerical results are compared regarding the cracking load and post-cracking behaviour, namely in terms of crack pattern and load-deflection response.(undefined

Evaluation of the dynamic behavior of a GFRP-SFRSCC hybrid footbridge

This paper presents results of numerical investigations on the dynamic behaviour of a hybrid footbridge made of glass fiber reinforced polymer (GFRP) pultruded profiles and a steel fibre reinforced self-compacting concrete (SFRSCC) slab. Finite element (FE) models were developed to simulate the dynamic response of the footbridge when subjected to human induced vibrations. Results obtained were compared with requirements defined in several standards in order to verify the performance of the footbridge regarding the fulfilment of comfort criteria. In addition, direct and indirect verification methods were compared to assess the applicability of the latter when used with GFRP-SFRSCC hybrid structures

Is a Combined Programme of Manual Therapy and Exercise More Effective than Usual Care in Patients with Non-Specific Chronic Neck Pain? A Randomized Controlled Trial

Objective: The aim of this study was to compare the effectiveness of a combined intervention of manual therapy and exercise (MET) versus usual care (UC), on disability, pain intensity and global perceived recovery, in patients with non-specific chronic neck pain (CNP). Design: Randomized controlled trial. Setting: Outpatient care units. Subjects: Sixty-four non-specific CNP patients were randomly allocated to MET (n = 32) or UC (n = 32) groups. Interventions: Participants in the MET group received 12 sessions of mobilization and exercise, whereas the UC group received 15 sessions of usual care in physiotherapy. Main measures: The primary outcome was disability (Neck Disability Index). The secondary outcomes were pain intensity (Numeric Pain Rating Scale) and global perceived recovery (Patient Global Impression Change). Patients were assessed at baseline, three weeks, six weeks (end of treatment) and at a three-month follow-up. Results: Fifty-eight participants completed the study. No significant between-group difference was observed on disability and pain intensity at baseline. A significant between-group difference was observed on disability at three-week, six-week and three-month follow-up (median (P25-P75): 6 (3.25-9.81) vs. 15.5 (11.28-20.75); P < 0.001), favouring the MET group. Regarding pain intensity, a significant between-group difference was observed at six-week and three-month follow-up (median (P25-P75): 2 (1-2.51) vs. 5 (3.33-6); P < 0.001), with superiority of effect in MET group. Concerning the global perceived recovery, a significant between-group difference was observed only at the three-month follow-up (P = 0.001), favouring the MET group. Conclusion: This study's findings suggest that a combination of manual therapy and exercise is more effective than usual care on disability, pain intensity and global perceived recovery.info:eu-repo/semantics/publishedVersio

Resting-state connectivity reveals a role for sensorimotor systems in vocal emotional processing in children

Voices are a primary source of emotional information in everyday interactions. Being able to process non-verbal vocal emotional cues, namely those embedded in speech prosody, impacts on our behaviour and communication. Extant research has delineated the role of temporal and inferior frontal brain regions for vocal emotional processing. A growing number of studies also suggest the involvement of the motor system, but little is known about such potential involvement. Using resting-state fMRI, we ask if the patterns of motor system intrinsic connectivity play a role in emotional prosody recognition in children. Fifty-five 8-year-old children completed an emotional prosody recognition task and a resting-state scan. Better performance in emotion recognition was predicted by a stronger connectivity between the inferior frontal gyrus (IFG) and motor regions including primary motor, lateral premotor and supplementary motor sites. This is mostly driven by the IFG pars triangularis and cannot be explained by differences in domain-general cognitive abilities. These findings indicate that individual differences in the engagement of sensorimotor systems, and in its coupling with inferior frontal regions, underpin variation in children’s emotional speech perception skills. They suggest that sensorimotor and higher-order evaluative processes interact to aid emotion recognition, and have implications for models of vocal emotional communication.info:eu-repo/semantics/acceptedVersio

Static, dynamic and creep behaviour of a full-scale GFRP-SFRSCC hybrid footbridge

A three-year research project (Pontalumis) was carried out for the development of an innovative simply supported hybrid footbridge, with 11 m of length and 2 m of width. The footbridge is composed of two pultruded I-shaped glass fibre reinforced polymer (GFRP) girders (400×200(×15) mm2) bonded and bolted to a 37.5 mm thick deck in steel fibre reinforced self-compacting concrete (SFRSCC). The present paper describes the material/structural concept of this footbridge, its design and construction process, and summarizes the response of the prototype when submitted to static short and long-term load tests, and dynamic load tests. The prototype was simple and fast to execute, presenting a reduced dead-weight of only about 3 tonf. The static and dynamic behaviour of the prototype as well as its long-term deflection fulfil standards’ requirements for footbridge structures and are in good agreement with conventional analytical and numerical design tools.AD
