    El Protomedicato navarro: itinerario de una investigación

    Get PDF
    En este trabajo se expone la metodología empleada en el estudio del Protomedicato navarro. Aprovechando la peculiar situación del reino de Navarra entre los siglos xw y XIX, durante los que mantuvo plena autonomía, se acometió el estudio del Protomedicato navarro a través de los fondos documentales de las demás instituciones administrativas y políticas del reino. Entre estas instituciones cabe destacar la Cofradía de médicos, cirujanos y boticarios de Pamplona, cuya existencia influyó en su evolución

    Pyridinium N-2´-pyridylaminide: synthesis of 3-aryl-2-aminopyridines through an intramolecular radical process

    Get PDF
    Tris(trimethylsilyl)silane (TTMSS) and azobisisobutironitrile (AIBN) promote the intramolecular heteroarylation of arenesulfonamides with pyridyl radicals under thermal conditions. The arenesulfonamides are easily prepared from pyridinium N-2′-pyridylaminide. The heteroarylation process involves pyridyl radical cyclization and ipso substitution.Financial support by the Comisión Interministerial de\ud Ciencia y Tecnología (CICYT, project BQU2001-1508)\ud and two grants, by the Universidad de Alcalá (A.

    This is the peer reviewed version of the following article: European Eating Disorders Review 24.4 (2016): 294-303, which has been published in final form at https://doi.org/10.1002/erv.2440. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-ArchivingThe aim of this study was to compare the family functioning of Spanish parents of patients with an eating disorder (ED) with that of carers of patients with substance-related disorders (SRDs) and families of healthy controls (HC). This cross-sectional study included 48 mothers and 45 fathers of 48 adolescent patients with an ED, 47 mothers and 37 fathers of 47 patients with an SRD and 66 mothers and 50 fathers of 68 HCs. Families of ED patients reported lower levels of criticism, symptom accommodation and negative caregiving experience than families of SRD patients. However, relatives of both ED and SRD patients reported similar levels of quality of life related to their mental health. Furthermore, families of HCs generally exhibited better scores on all scales assessing their caregiving experiences. Regarding gender differences, there was a tendency in mothers, primarily those from the ED group, to report more adverse experiences as caregivers compared with fathers. Symptoms characteristic to each disorder may be associated with differential patterns of family functioning and may require specifically tailored family interventions. Early family intervention in adolescence is crucial, as relatives' quality of life does not seem to have been badly affected at this point in the course of the illnessDr Sepulveda has a post-doctoral Ramon and Cajal scholarship from the Spanish Ministry of Science and Innovation (RYC-2009-05092) as well as a project funding from the same Ministry (PSI2011-23127).

    Este artículo presenta un estudio exploratorio inicial sobre el alumnado que cursó el MOOC titulado “Creación y retoque de imágenes con software libre”. Los cursos en línea masivos y abiertos (MOOC) se han popularizado en pocos años y cada vez son más las personas que los utilizan como medio de aprendizaje para su desarrollo personal y profesional. Su aparición ha venido acompañada de críticas debido a sus propias características, pero hay escasos estudios que preguntan a los estudiantes. A través de un método descriptivo se diseñó un cuestionario para recabar datos sobre las variables personales asociadas al alumnado del MOOC, sus motivaciones y el grado de satisfacción que manifestaron al término del proceso formativo. Los resultados obtenidos permitieron definir el perfil del alumno tipo, que es un hombre con estudios universitarios, de entre 26 y 45 años. Reside en España y trabaja por cuenta ajena. Ha realizado antes actividades formativas online y no es la primera vez que realiza un MOOC. El estudio concluyó que la motivación del alumnado para realizar el MOOC es la necesidad de mejorar su currículum y adquirir nuevos conocimientos. Motivación que se cumplió a tenor de los elevados niveles de satisfacción que manifestaron.This article presents an initial exploratory study about the students who attended the MOOC entitled “Creation and retouching of images with free software”. Massive and Open Online Courses (MOOC) have become popular in a few years and more and more people are using them as a means of learning for their personal and professional development. Their appearance has been accompanied by criticism due to their own characteristics, but there are few studies that ask students. Through a descriptive method a questionnaire was designed to collect data on the personal variables associated with the MOOC students, their motivations and the degree of satisfaction they showed at the end of the training process. The results obtained allowed to define the profile of the type student, who is a man with university studies, between 26 and 45 years. He lives in Spain and is employee. He has previously conducted online training activities and is not the first time he makes a MOOC. The study concluded that the motivation of the students to carry out the MOOC is the need to improve their curriculum and acquire new knowledge. Motivation was fulfilled in view of the high levels of satisfaction they expressed
