La divulgación radiofónica de la alimentación y la higiene infantil en la España de la Segunda República (1933-1935)

El trabajo analiza la incorporación de medios tecnológicos, en particular la radio, en el proceso de divulgación del conocimiento sobre la salud infantil durante la Segunda República española. En el marco de la campaña sanitaria contra la mortalidad infantil que puso en marcha la Segunda República en la década del 30, la Asociación Española de Médicos Puericultores Titulados, en colaboración con Unión Radio, organizó dos ciclos de conferencias radiofónicas que pretendían explicar, a través de un discurso divulgativo de tono descriptivo dirigido a las clases populares, las nociones fundamentales de la higiene y la alimentación infantil, e impulsar una cultura de la prevención, guiada y orientada por los dictados de los expertos. Se trataba de una acción de propaganda y divulgación que tenía su continuidad en el medio familiar y comunitario a través de la actuación de las enfermeras visitadoras puericultoras, contemplando a las madres como población diana.

Experiencia de transferencia de conocimiento en el proyecto de investigación ITSAL (Inmigración, Trabajo y SALud) con representantes de la población diana

Se describe una experiencia de transferencia de conocimiento entre investigadores del proyecto ITSAL (Inmigración, Trabajo y SALud) y representantes de asociaciones que trabajan con población inmigrante para discutir los resultados obtenidos en esta investigación y las líneas de futuro. Para ello se llevó a cabo una reunión en la que participaron tres investigadoras y 18 representantes de 11 instituciones. Tras una exposición de la metodología y los resultados del proyecto ITSAL, todos los asistentes comentaron los resultados presentados y líneas de investigación de interés. Se pusieron de manifiesto coincidencias entre ambas partes y también se obtuvieron propuestas de interés para el proyecto ITSAL. Entendemos el proceso descrito como una aproximación a la validación social de algunos resultados principales del proyecto. Esta experiencia nos ha permitido abrir un canal de comunicación con la población diana del estudio, en línea con la necesaria interacción de investigadores y población.

Census of breeding birds and population trends of the Dupont’s lark Chersophilus duponti in eastern Spain

We present the results of a breeding census of Dupont’s Lark carried out in the Autonomous Community of Valencia in 2011 using the mapping method and an analysis of the recent trend for this population. The population was estimated at 44-47 males, located in five habitat patches of the Rincón de Ademuz, in zones where the species had been detected previously. Density in these patches fits within values expected according to the relation between patch size and density found in the populations of the nearby provinces. Comparison to previous studies reveals that population of Valencia has suffered an annual decline rate of around 10% on average, thus the implementation of a conservation plan is required to ensure the survival of the species in the study area.

Indicators of obesity and the educational attainment of the Czech female population

The aim of this paper was to evaluate the relationship between selected indicators of obesity and the highest completed level of education in the adult female population of the Czech republic. As basic indicators of obesity, these following parameters were selected and measured via the bioimpedance method on the device InBody 720: BMI, WHR (waist-to-hip ratio), % body fat, % skeletal muscle mass, fitness score. The educational attainment of the tested women was inquired by a questionnaire. Based on the responses, we subsequently divided our sample into four categories according to the level of education: primary education, secondary education-apprenticeship, secondary education-graduate diploma, and university. The research was realized within the project CZ.1.07/2.3.00/20.0044. The measurements on the device InBody 720 and the accompanying survey were conducted between 2011-2013 in different regions of the Czech Republic. The sample consisted of 754 women divided into 3 age groups (18-39, 40-59, 60+ years). Based on the results (p<0.05), we can say that average values of the indicators obesity (BMI: 22.76, 24.88, 26.49 kg/m2, WHR: 0.85, 0.88, 0.90 and % body fat: 25.76, 30.23, 34.62%) increase with the increasing age of examined women. The average values of the fitness score (75.53, 73.86, 70.04 points) and % skeletal muscle mass (40.78, 38.15, 33.95%) decrease with increasing age. With regard to the educational attainment, women with secondary education-apprenticeship achieved the worst results. In contrast, the values in university educated women were the best in most indicators of obesity.

A new survey of cool supergiants in the Magellanic Clouds

Aims. In this study we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of the brightness distribution of these stars, building a more representative dataset with which to extrapolate their behaviour to other Galactic and extra-galactic environments. Methods. We select candidates using only near infrared photometry, and with medium resolution multi-object spectroscopy, we perform spectral classification and derive their line-of-sight velocities, confirming the nature of the candidates and their membership in the clouds. Results. Around two hundred new red supergiants have been detected, hinting at a yet to be observed large population. Using near- and mid-infrared photometry we study the brightness distribution of these stars, the onset of mass-loss, and the effect of dust in their atmospheres. Based on this sample, new a priori classification criteria are investigated, combining mid- and near-infrared photometry to improve the observational efficiency of similar programs to this.
