The Method for the Clarinet, by Antonio Romero. Some considerations about its first edition
La figura de Antonio Romero quizá nos sea familiar a los clarinetistas gracias, en
gran medida, al sistema de clarinete que desarrolló en París junto al constructor Paul Bié
a mediados del siglo XIX. Al aproximarnos a su estudio, nos encontraremos con uno de
los personajes más activos e interesantes de la música española del siglo XIX. Romero no
sólo fue un clarinetista excepcional; también fue editor, oboísta brillante, crítico musical,
académico, dinamizador de la vida musical madrileña con la promoción de orquestas y
de una ópera nacional española, y fundador del Salón Romero, la sala de conciertos más
importante del Madrid de su época donde, entre otros muchos actos, Isaac Albéniz haría
su debut madrileño en 1886, Pau Casals tocaría en su etapa de estudiante en 1895 y Miguel
Yuste, otro excepcional clarinetista, estrenaría en España las obras para clarinete de Brahms
poco después de ser compuestas.
El objetivo de este artículo es establecer las circunstancias que rodearon la primera
edición del «Método completo de clarinete» de Antonio Romero. También analizaremos la relación
entre el Conservatorio de Madrid y el citado método, estudiando los documentos custodiados
en la Biblioteca de dicho centro. Como veremos, el año de la primera edición ha sido un dato inconsistente desde las menciones iniciales a la obra, por lo que propondremos una fecha para
datarla, teniendo en cuenta la documentación encontrada.Antonio Romero’s figure may be familiar to clarinettists thanks largely to the clarinet system
developed in Paris in the mid-nineteenth century with the builder Paul Bié. As we approach the study,
we will find one of the most active and interesting characters of Spanish music of the nineteenth
century. Romero was not only an outstanding clarinettist: he was also an editor, an amazing oboist,
a music critic, an academic, a cultural activist of Madrid’s musical life promoting orchestras and a
Spanish national opera. He was also the founder of the Salón Romero, the most important concert
hall of Madrid of his era. There, amongst many other concerts, Isaac Albéniz made his debut in
Madrid in 1886, Pau Casals gave a concert/played music/acted in his student period in 1895 and,
Miguel Yuste, another outstanding clarinetist, premiered in Spain the Brahms clarinet works shortly
after being composed.
The aim of this article is to establish the circumstances surrounding the Antonio Romero’s
first edition of the "Complete Method for the Clarinet". We will also analyze the relationship between the
Madrid Conservatory and the aforementioned method, studying documents held by the Library of
that centre. As we shall see, the year of the first edition has been an inconsistent data from initial
references to the work, so we will propose a date, considering the documents found
La retórica de los argumentos: Persuasión racional y manipulación visual
A partir de dos preguntas claves de la teoría de la argumentación visual, el presente trabajo
plantea como hipótesis de investigación que la argumentación visual existe y que las imágenes
pueden presentar razones genuinas, y, por tanto, servir para exponer argumentos,
particularmente en publicidad.
Se empezará por contextualizar los orígenes de la argumentación visual, para a continuación
explorar la visión perspectivista de la argumentación, junto con una revisión crítica. A partir de
este marco, caracterizará el concepto de argumentar y el de argumentación visual. A
continuación, se explorarán las características propias de la argumentación visual y sus
mecanismos de cómo se insertan las imágenes en los argumentos. Por último, se realizará un
análisis específico de la relación de la argumentación visual, la publicidad y cómo expresar
razones con imágenes.Starting from two key questions of the theory of visual argumentation, the present work raises
as a research hypothesis that visual argumentation exists and that images can present genuine
reasons, and, therefore, serve to present arguments, particularly in advertising.
It will begin by contextualizing the origins of visual argumentation, and then exploring the
perspectivist view of argumentation, along with a critical review. From this framework, the
concepts of argumentation and visual argumentation will be characterized. Next, the
characteristics of the visual argumentation and its mechanisms of how the images are inserted
in the arguments will be explored. Finally, a specific analysis of the relationship of visual
argumentation, advertising and how to express reasons with images will be carried out.Departamento de Filosofía (Filosofía, Lógica y Filosofía de la Ciencia, Teoría e Historia de la Educación, Filosofía Moral, Estética y Teoría de las Artes)Departamento de Lingüística General, Lenguas Modernas, Lógica y Filosofía de la Ciencia.

Psychometric Properties of the Spanish Versions of EQ-5D-Y-3L and EQ-5D-Y-5L in Children with Cancer: A Comparative Study
Background: The recent published version with five levels of response of EQ-5D-Y
needs to be studied in children with chronic illness. For this, the aim of the present study was
to assess and compare the psychometric properties of EQ-5D-Y-3L and EQ-5D-Y-5L in terms of
feasibility, ceiling effect, redistribution properties, informativity and inconsistence responses in
children with cancer. (2) Methods: A core set of self-report tools, including the Spanish version of
EQ-5D-Y-3L and EQ-5D-Y-5L, were administered to children drawn from the population with cancer.
EQ-5D-Y-3L and EQ-5D-Y-5L were evaluated in terms of feasibility, ceiling effects, redistribution
properties and differences in absolute and relative informativity. (3) Results: A total of 73 children
(9.7 ± 2.3 years old) from the population with cancer participated in the study. No missing data in the
new EQ-5D-Y-5L were visualized, so the feasibility was acceptable. EQ-5D-Y-5L showed a low ceiling
effect in all dimensions with relative changes from EQ-5D-Y-3L to EQ-5D-Y-5L of between 15.3% and
42.4% for the dimensions and 44.6% for the overall system. Compared to EQ-5D-Y-3L, EQ-5D-Y-5L
provided a better distribution of the severity of the problem in the five levels of response. The
absolute informativity (Shannon’s index) did not show statistically significant differences between
EQ-5D-Y-3L and EQ-5D-Y-5L in all dimensions and the overall system. (4) Conclusions: EQ-5D-Y-5L
is feasible, presenting a low ceiling effect and high discriminative powerThis work was financially supported by the EuroQol Research Foundation. EuroQol Research

Efectes de l'entrenament aquàtic i posterior desentrenament sobre la percepció i intensitat del dolor i el nombre de punts sensibles de dones amb fibromiàlgia
Introducció i objectius: El símptoma més freqüent i característic de la fibromiàlgia és el dolor generalitzat i difús. El propòsit d'aquest estudi va ser avaluar els efectes de 12 setmanes d'entrenament en aigua calenta i posterior desentrenament sobre la percepció i intensitat de dolor i el nombre de punts sensibles al dolor en dones amb fibromiàlgia
Mètodes: Trenta cinc pacients van ser distribuïdes aleatòriament en dos grups: un grup experimental (n = 18), que va fer 3 sessions setmanals d'exercici físic de 60 min cadascuna, i el grup control (n = 17), que no va rebre l'esmentat entrenament addicional. El dolor es va avaluar usant les dimensions de dolor del Fibromyalgia Impact Questionnarie i Short Form 36. També es va avaluar el nombre de punts sensibles al dolor.
Resultats: Després de 12 setmanes de programa es van observar millores significatives en el grup experimental respecte del grup control en la intensitat i la percepció del dolor. No obstant això, després del període de desentrenament, només es va mantenir la millora en la dimensió de "dolor corporal" del Short Form 36. El nombre de punts sensibles al dolor es va mantenir sense canvis en ambdós grups durant tot el protocol de programa.
Conclusions: Un programa de 12 setmanes d'entrenament en aigua calenta, unit al tractament mèdic clàssic, va ser efectiu per reduir el dolor en dones amb fibromiàlgia. Després d'un període semblant sense entrenament físic, les millores en dolor es van mantenir parcialment. Amb tot, el programa d'entrenament no va tenir efectes en la reducció del nombre de punts sensibles al dolor
Fitness and health-related quality of life dimensions in community-dwelling middle aged and older adults
<p>Abstract</p> <p>Background</p> <p>The aim of the present study was to identify the physical fitness (PF) tests of a multi-component battery more related to the perception of problems in each dimension of the health-related quality of life (HRQoL) assessed by the EuroQol 5 dimensions 3 level questionnaire (EQ-5D-3L) in community-dwelling middle-aged and older adults</p> <p>Methods</p> <p>A cross-sectional study was conducted with 7104 participants (6243 females and 861 males aged 50-99 years) who were recruited in the framework of the Exercise Looks After You Program, which is a public health program designed to promote physical activity (PA) in community-dwelling middle-aged and older adults. Participants were assessed by the EQ-5D-3L questionnaire and a battery of fitness tests. The responses to each EQ-5D-3L dimension were collapsed into a two-tier variable consisting of «perceive problems» and «do not perceive problems». Correlation coefficients for the relationships between the HRQoL variables, between the PF variables, and between the HRQoL and PF variables were obtained. Two logistic regression models, one adjusted and one unadjusted, were developed for each EQ-5D-3L dimension.</p> <p>Results</p> <p>There were significant correlations between all variables except anxiety/depression and the back scratch test. The PF tests that correlated best with the HRQoL dimensions were the Timed Up-and-Go Test (TUG) and the 6-min walk; pain/discomfort and anxiety/depression correlated less well. All PF tests correlated, especially the TUG and 6-min walk tests. Unadjusted logistic models showed significant goodness of fit for the mobility and pain/discomfort dimensions only. Adjusted logistic models showed significant goodness of fit for all dimensions when the following potential confounding variables were included: age, gender, weekly level of PA, smoking and alcohol habits, body mass index, and educational level. For all dimensions, the highest odds ratios for the association with PF tests were with the TUG; this was observed with both the unadjusted and adjusted models.</p> <p>Conclusions</p> <p>The perception of problems, as measured by the EQ-5D-3L dimensions, was associated with a lower level of fitness, particularly for those dimensions that relate more closely to physical components. The PF tests that associated most closely with the perception of problems in the HRQoL dimensions were the TUG and the 6-min walk. This information will aid the design and assessment of PA programs that aim to improve HRQoL.</p
GPS-aided Visual Wheel Odometry
This paper introduces a novel GPS-aided visual-wheel odometry (GPS-VWO) for
ground robots. The state estimation algorithm tightly fuses visual, wheeled
encoder and GPS measurements in the way of Multi-State Constraint Kalman Filter
(MSCKF). To avoid accumulating calibration errors over time, the proposed
algorithm calculates the extrinsic rotation parameter between the GPS global
coordinate frame and the VWO reference frame online as part of the estimation
process. The convergence of this extrinsic parameter is guaranteed by the
observability analysis and verified by using real-world visual and wheel
encoder measurements as well as simulated GPS measurements. Moreover, a novel
theoretical finding is presented that the variance of unobservable state could
converge to zero for specific Kalman filter system. We evaluate the proposed
system extensively in large-scale urban driving scenarios. The results
demonstrate that better accuracy than GPS is achieved through the fusion of GPS
and VWO. The comparison between extrinsic parameter calibration and
non-calibration shows significant improvement in localization accuracy thanks
to the online calibration.Comment: Accepted by IEEE ITSC 202
