La vulgarisation scientifique et les doctorants : mesure de l'engagement, exploration d'effets sur le chercheur
2018
We ask two questions: what are the factors that influence researchers’ public engagement activities (PEA)? And what are the impacts of these activities on the researcher? After presenting a historical overview of PEA, we analyze 20 surveys carried out between 1967 and 2014. We identify some global trends: PEA is generally positively perceived, researcher’s engagement is occasional but robust. Besides those trends some differences appear between studies based on theoretical models and empirical studies: the latter report complaints such as lack of time or lack of recognition, whereas theoretical-based ones challenge these statements.To further explore our two questions, we used two approache…
Spectral decomposition of cerebrovascular and cardiovascular interactions in patients prone to postural syncope and healthy controls.
2022
We present a framework for the linear parametric analysis of pairwise interactions in bivariate time series in the time and frequency domains, which allows the evaluation of total, causal and instantaneous interactions and connects time- and frequency-domain measures. The framework is applied to physiological time series to investigate the cerebrovascular regulation from the variability of mean cerebral blood flow velocity (CBFV) and mean arterial pressure (MAP), and the cardiovascular regulation from the variability of heart period (HP) and systolic arterial pressure (SAP). We analyze time series acquired at rest and during the early and late phase of head-up tilt in subjects developing or…
Research on ecological design to enhance comfort in open spaces of a city (Valencia, Spain). Utility of the physiological equivalent temperature (PET)
2013
For many years now, research has focused on issues concerning making cities easier to live in and some of the most important of these concern climatology and thermal comfort issues. There is also a growing awareness of the importance of open spaces and green areas, as key elements in providing opportunities for human interaction, leisure and physical exercise. They are important for all inhabitants, but particularly so for children and the elderly population. Of especial interest are the studies which have examined the interaction of comfort with the urban climate. This issue was studied throughout the twentieth century, but recently the role which can be played by biometeorological indices…
Intermittent Horner's syndrome on alternate sides: a hint for locating spinal lesions.
1980
A patient with a cervical intramedullary ependymoma is described who exhibited a Horner's syndrome on alternate sides. Pharmacological study demonstrated damage to the pre-ganglionic sympathetic neurons. Disregarding cases with the Shy-Drager syndrome, three comparable case reports have been found in the literature where the fluctuating expression of Horner's syndrome, alternating from one side to the other, was attributable to a lesion of the cervical spinal cord. In contrast to the present patient, the pharmacological responses of these patients indicated a lesion of the central sympathetic pathway.
Moral and Civic Education. The New School’s Contribution
2014
Our aim is to establish a reflexive analysis about the way in which the New Education’s movement understands morality and the way it is meant to be taught, as well as its particular entail with civic education. We offer a synthesis of the investigation, which has its base on some not vey spread primary sources of authors and institutional organs of the movement. With it we clarify the meaning and the ways through which pedagogical currents shaped, in the beginning of the 20th century, a new way of conceiving the practice of these formative areas. We also identify the perspectives of methodological renovation that in this moment arose. These contributions, the result of which are summarized …
Decisions of higher education students according to the social environment. A conjecture based on reflexivity, biograficity and empirical research
2019
Este trabajo tiene como objetivo presentar una conjetura epistemológica que combina un marco de análisis basado en la capacidad reflexiva, como parte intrínseca del desarrollo de la investigación social cualitativa y que denominamos como el salto de lo empírico a lo teórico, además de incorporar la perspectiva teórica de la biograficidad para el estudio de las trayectorias educativas en educación superior. Esta propuesta surge desde nuestra propia experiencia investigadora adquirida en diversas investigaciones dentro de una línea sobre transiciones y trayectorias en educación superior en el sistema español. Para enmarcar este salto de lo empírico a lo teórico presentamos, como resultado, un…
Skin innervation at different depths correlates with small fibre function but not with pain in neuropathic pain patients
2012
Background: Neuropathy can lead not only to impaired function but also to sensory sensitization. We aimed to link reduced skin nerve fibre density in different levels to layer-specific functional impairment in neuropathic pain patients and tried to identify pain-specific functional and structural markers. Methods: In 12 healthy controls and 36 patients with neuropathic pain, we assessed clinical characteristics, thermal thresholds (quantitative sensory testing) and electrically induced pain and axon reflex erythema. At the most painful sites and at intra-individual control sites, skin biopsies were taken and innervation densities in the different skin layers were assessed. Moreover, neurona…

La prevención del consumo de drogas en España: evolución y propuestas para la reflexión
2005
El presente trabajo hace una revisión de la prevención realizada en España en los últimos años, con algunas referencias a las influencias recibidas de otros países y con especial atención a la efectividad de las actuaciones puestas en marcha.
