Comunicació local i de proximitat
Research on local Valencian communication is, analytically speaking, heter - ogeneous and patchy. General overviews on the entire Valencian area are lacking. Predominating the literature are books summarizing conclusions of diverse regional communication conferences held from 1987 to 2005. Noteworthy are the volumes published by the València Generalitat, the Federació Valenciana de Municipis i Províncies, the Unió de Periodistes Valencians, and the Universitat Jaume I in Castelló, comprising studies on the communication experiences and tendencies of numerous local and regional media. These studies, carried out with analytical rigor by journalism specialists and professionals, give the authors¿ own visions of the structural deficits and strong points of local Valencian media of the last 30 years. La investigació de la comunicació local valenciana es caracteritza per la heterogeneïtat i la dispersió analítica. Manquen les monografies generals que abasten tot el territori. La producció bibliogràfica predominant són llibres que recullen les conclusions de diverses jornades de comunicació de proximitat realitzades durant els anys 1987-2005. Destaquen els volums editats per la Generalitat Valenciana, la Federació Valenciana de Municipis i Províncies, la Unió de Periodistes Valencians i la Universitat Jaume I de Castelló. Aquests compendis analitzen experiències i tendències comunicatives de bastants mitjans locals i comarcals. Són estudis fets amb rigor analític per especialistes i professionals del periodisme, els quals donen la seua visió particular sobre els dèficits estructurals i punts forts dels mitjans locals valencians dels últims trenta anys
La guarda y custodia compartida en el derecho autonómico. Estado actual de la cuestión
Tras la promulgación de las últimas leyes en el Derecho autonómico sobre esta
institución, a la vista de los avances jurisprudenciales producidos, así como ante la más que
inminente sentencia del Tribunal Constitucional que resolverá sobre la constitucionalidad o no de la
Ley 5/2011 de la Generalitat Valenciana, en el presente artículo se analiza la situación actual
existente en el Derecho autonómico en torno a la institución de la guarda y custodia compartida, así
como la previsible situación en la que va a quedar la referida institución en el ámbito de la
Comunidad Valenciana ante la hipotética derogación de la Ley de custodia compartida.This paper reviews the current situation concerning the institution of joint custody in
the regional legal system and its eventual development in Valencia region after the expected repeal of
the Shared Custody Law following the enactment of the latest regional laws concerning this
institution, the jurisprudencial progress made, as well as the imminent judgement of the
Constitucional Court regarding the constitutionality of the Law 5/2011 of the Generalitat Valenciana
La configuració de la premsa valencianista democràtica (1976-1987)
The end of Franco's repressive system against the Valencia's culture built up a favorable environment to the development of the catalan press. During the democratic transition and the first autonomical legislature, between 1976 and 1987 , there were born in Valencia 112 magazines written in catalan or bilingual with a preferred use of this language , which form the first valencianista Printing-Press of the democracy. To analyze it I have realized an investigation in thirteen newspaper libraries and files. This has allowed to make a statistical study of the sector and determine his characteristics. One of the conclusions of this article is that these publications did not consolidate a normalized market, both readers and advertising , nor were decisive in linguistic standardization. These media suffered many political and economic difficulties in a historical context disturbed by the so-called Battle of Valencia and conservative regionalism known as 'blaverisme', which questions the unity of catalan language and its standardization. La fi del sistema repressor franquista contra la cultura valenciana va crear un ambient favorable al desenvolupament de la premsa en català. Durant la transició democràtica i la primera legislatura autonòmica, entre 1976 i 1987, van nàixer al País Valencià 112 revistes escrites en català o bilingües amb un ús preferent d'aquesta llengua, que configuren la primera premsa valencianista de la democràcia. Per analitzar-la he realitzat una recerca en tretze centres hemerogràfics i arxius. Això ha permés fer un estudi bibliomètric del sector per a determinar les seues característiques. Una de les conclusions d'aquest l'article és que aquestes publicacions no van consolidar un mercat normalitzat, tant de lectors com publicitari, ni tampoc han estat determinants en la normalització lingüística. Aquests mitjans de comunicació van sofrir entrebancs polítics i econòmics en un context històric enterbolit per l'anomenada Batalla de València i el regionalisme conservador conegut com blaverisme, que qüestiona la unitat de la llengua catalana i la seua normalització
Fomento de la interacción social (conducta prosocial): correlatos neurobiológicos en el Transtorno de Espectro Autista
Recientemente se ha observado un enorme incremento en la prevalencia del Trastorno de Espectro Autista (TEA) cuyos síntomas nucleares están relacionados con el déficit marcado en la comunicación e interacción social. El objetivo del trabajo fue realizar una revisión de la literatura sobre los factores neurobiológicos implicados en el fomento de la conducta social (conducta prosocial) en el TEA, en la última década. Las hormonas y neurotransmisores más relevantes serían la oxitocina, la vasopresina, la serotonina, andrógenos y estrógenos. En cuanto a neuroanatomía y sistema neuronales destacan la ínsula anterior, la amígdala, la zona fronto-parietal, el giro fusiforme y el sistema de neuronas espejo.Recently a huge increment in the prevalence of Autism Spectrum Disorder (ASD) has been observed. The core diagnostic features are related to communication and social interaction impairment. The aim of the present work was to review the neurobiological factors involved in promoting social behavior (prosocial behavior) exhibited by persons with ASD in the last decade. Oxytocin, vasopressin, serotonin, androgens and estrogens are the most important hormones and neurotransmitters involved. With regard to neuroanatomy and neural systems, the anterior insula, amygdala, fronto-parietal area, fusiform gyrus and neurons mirror system are the most remarkable
Effects of central and peripheral fatigue on impact characteristics during running
Fatigue and impact can represent an injury risk factor during running. The objective of this study was to compare the impact transmission along the locomotor system between the central and peripheral fatigued states during running. Tibial and head acceleration as well as shock attenuation in the time- and frequency-domain were analyzed during 2-min of treadmill running in the pre- and post-fatigue state in eighteen male popular runners (N = 18). The impact transmission was measured before and after a 30-min central fatigue protocol on the treadmill or a peripheral fatigue protocol in the quadricep and hamstring muscles using an isokinetic dynamometer. The time-domain acceleration variables were not modified either by peripheral or central fatigue (p > 0.05). Nevertheless, central fatigue increased the maximum (p = 0.006) and total (p = 0.007) signal power magnitude in the high-frequency range in the tibia, and the attenuation variable in the low- (p = 0.048) and high-frequency area (p = 0.000), while peripheral fatigue did not cause any modifications in the frequency-domain variables (p > 0.05). Furthermore, the attenuation in the low (p = 0.000)- and high-frequency area was higher with central fatigue than peripheral fatigue (p = 0.003). The results demonstrate that central fatigue increases the severity of impact during running as well as the attenuation of low and high components
Control predictivo con restricciones e independiente de modelo para el p´endulo de Furuta
[Resumen] Este trabajo presenta el control de seguimiento de un péndulo Furuta basado en el diseño de dos lazos paralelos con restricciones, rechazo activo de perturbaciones y predicción de salidas. Para cada subsistema, se asume que la planta gobernada tiene una dinámica de primer orden más integrador (FOPI). Así, se calcula una ley de control predictivo aplicando una estrategia de horizonte deslizante en dicha planta (FOPI). La diferencia entre la dinámica real y el modelo de predicción asumido se compensa mediante el mecanismo de rechazo de perturbaciones heredado del control activo de rechazo de perturbaciones (ADRC) e incorporado en los lazos. Para el diseño del control no se realiza ninguna identificación de modelos ni linealización matemática. Además, la estrategia permite incorporar las restricciones reales del sistema. Este trabajo valida con resultados prometedores la arquitectura denominada Modified Active Disturbance Rejection Predictive Control (MADRPC) mediante la estabilización de un sistema mecánico subactuado considerando las variables restringidas y en ausencia de un modelo nominal, en contraste con el enfoque estándar en el Control Predictivo de Modelos (MPC) en espacio de estados.[Abstract] This paper presents the tracking control of a Furuta pendulum based on the design of two parallel-constrained loops with active disturbance rejection and outputs predictions. For each subsystem, it is assumed that the governed plant resembles firstorder plus integrator (FOPI) dynamics. So, a predictive control law is computed by applying a receding horizon strategy in such FOPI plant. The mismatch between the actual dynamics and the assumed prediction model is compensated through the disturbance rejection mechanism inherited from the Active Disturbance Rejection Control (ADRC) incorporated in the loops. No modelling identification or mathematical linearisation is performed for the control design. Moreover, the strategy allows the incorporation of the actual system constraints. This work validates with promising results the architecture named Modified Active Disturbance Rejection Predictive Control (MADRPC) by stabilising a sub-actuated mechanical system considering the constrained variables and in the absence of a nominal model, in contrast to the standard approach in the state-space Model Predictive Control (MPC).Colombia.

Dos lienzos devocionales del siglo XVIII montados en ambas caras de un mismo bastidor, procedentes de Cella (Teruel). Estudio histórico-técnico y proceso de intervención
Una de las características fundamentales del presente trabajo es el estudio de una obra compuesta por dos lienzos montados sobre un único bastidor. Se trata de un caso extraordinario, y paradigmático en la forma de presentación de dos temas devocionales sin solución de continuidad. Por una parte, tendríamos la representación hagiográfica del Martirio de Santa Orosia y por la otra La aparición de la Virgen del Pilar a Santiago en la ciudad de Zaragoza. Con este trabajo se pretende estudiar la fórmula de presentación técnica de la obra, su estado de conservación, así como una revisión iconográfica de las escenas representadas. En una segunda fase del trabajo se propondrá una propuesta de intervención y unas recomendaciones de conservación.One of the fundamental characteristics of the present work is the study of a work composed of two canvases mounted on a single frame. It is an extraordinary case, and paradigmatic in the form of presentation of two devotional subjects without solution of continuity. On the one hand, we would have the hagiographic representation of the Martyrdom of St. Orosia and on the other the appearance of the Virgin of the Pillar to Santiago in the city of Saragossa.
This work intends to study the technical presentation formula of the work, its state of conservation as well as an iconographic revision of the scenes represented. A second phase of the work will propose the intervention proposal and some conservation recommendations.Sanchis Martínez, C. (2017).

Evaluation of impact-shock on gait after the implementation of two different training programs in older adults
Gait is negatively affected with increasing age. It is widely accepted that training produces physical-functional improvements in older adults, which can be assessed with numerous physical-functional tests. However, very few studies have been carried out using accelerometry to analyse the training effect on kinetic and kinematic variables in older adults, and there is no one that investigate the effects of two different training programs. Therefore, the aim of this study is to analyse the effects of an interval-walking program and a multicomponent program on the acceleration impacts, shock attenuation, step-length, stride frequency, and gait speed in older adults. Methods: 23 participants were divided into multicomponent training group [n = 12, 7 female, 71.58 (4.56) years] and interval-walking group [n = 11, 6 female, 69.64 (3.56) years]. We evaluated the participants using three triaxial accelerometers, placing one on the distal end of each tibia and one on the forehead. Findings: After 14 weeks' of training, the maximum acceleration values both for the head accelerometer and for the non-dominant tibia, as well as the attenuation in the same leg, increased in the multicomponent training group. The maximum acceleration values for the head and the stride frequency also increased in the intervalwalking group. Lower limb strength improved in both groups. Interpretation: Given the benefits we found for each of these programs, we encourage their consideration when planning older adults training programs and suggest that multicomponent programs should be introduced prior to the start of walking-based programs
