Chromospheric observations and magnetic configuration of a supergranular structure
Unipolar magnetic regions are often associated with supergranular cells. The
chromosphere above these regions is regulated by the magnetic field, but the
field structure is poorly known. In unipolar regions, the fibrillar arrangement
does not always coincide with magnetic field lines, and polarimetric
observations are needed to establish the chromospheric magnetic topology. In an
active region close to the limb, we observed a unipolar annular network of
supergranular size. This supergranular structure harbours a radial distribution
of the fibrils converging towards its centre. We observed this structure at
different heights by taking data in the FeI 6301-6302 {\AA}, H-\alpha, CaII
8542 \AA\ and the CaII H&K spectral lines with the CRISP and CHROMIS
instruments at the Swedish 1-m Solar Telescope. We performed Milne-Eddington
inversions of the spectropolarimetric data of FeI and applied the weak field
approximation to CaII 8542 \AA\ data to retrieve the magnetic field in the
photosphere and chromosphere. We used magnetograms of CRISP, HINODE/SP and HMI
to calculate the magnetic flux. We investigated the velocity using the
line-of-sight velocities computed from the Milne-Eddington inversion and from
Doppler shift of the K feature in the CaII K spectral line. To describe the
typical spectral profiles characterising the chromosphere above the
supergranular structure, we performed a K-mean clustering of the spectra in
CaIIK. The photospheric magnetic flux is not balanced. The magnetic field
vector at chromospheric heights, retrieved by the weak field approximation,
indicates that the field lines within the supegranular cell tend to point
inwards, and might form a canopy above the unipolar region. In the centre of
the supergranular cell hosting the unipolar region, we observe a persistent
chromospheric brightening coinciding with a strong gradient in the
line-of-sight velocity.Comment: 12 pages, 12 figures, accepted for publication in A&
Understanding the Meaning of Conformity to Feminine Norms in Lifestyle Habits and Health: A Cluster Analysis
Background: Gender roles impact different spheres of life and lead women to behavioral patterns and lifestyle habits associated with femininity, generating important differences between men and women in health. The present study analyzed relationships between conformity to the feminine norms and different lifestyle indicators: Educational level, marital status, alcohol consumption, tobacco consumption, sleeping hours, social support, and physical activity. Additionally, cluster analysis was developed in order to identify different patterns of gender role conformity.
Methods: The sample was made up of 347 women age 18–70 from Spain. Data collection was conducted during 2014.
Results: Multiple logistic regression analyses produced odds ratios showing that women with lower feminine role conformity were more likely to use tobacco and alcohol, but less likely to share their lives with someone. Cluster analysis found four different profiles of gender role conformity related to different patterns of alcohol consumption and marital status.
Conclusions: Conformity to feminine norms was associated with basic affective conditions such as sharing life with others and with alcohol and tobacco consumption, but not with physical activity, social support, and sleep duration. Whereas tobacco and alcohol use have important health implications, public health systems should pay attention to gender-related variables in order to design and implement specific prevention programs
I want to be Marifé de Triana. An experience for the development of Emotional Intelligence through Music Therapy
Presentamos el desarrollo de un programa denominado “¡Escúchame!” basado en la experiencia “Mami Sounds” llevada a cabo en Argentina por Federico (2007), teniendo como hilo conductor la Musicoterapia. Nuestro propósito es desarrollar la inteligencia emocional de personas con Síndrome de Down, mediante la estimulación sensorial a través de la música, que genera y despierta toda clase de sentimientos y emociones. Para la evaluación del programa, se han elaborado instrumentos de carácter cualitativo y cuantitativo que nos indican una mejora en las conductas sociales y afectivas de la muestra participante tras la implementación del programa.We show the results of a study called “Listen to me”, based on the experience developed in Argentina by Federico (2007), where the leitmotiv is the Music therapy in a sample of people with disabilities, specifically Down syndrome. We implement a programme which mainly works emotional intelligence by using music of different styles. Our aim is to develop the emotional intelligence of people with Down syndrome, by the sensory stimulation through music, which generates and raises all types of feelings and emotions. Results show there is an improvement in socialand affective attitudes and behaviors of the people participating in this experience after the implementation of the programme.peerReviewe
Lateral downflows in sunspot penumbral filaments and their temporal evolution
© 2015. The American Astronomical Society. All rights reserved.. We study the temporal evolution of downflows observed at the lateral edges of penumbral filaments in a sunspot located very close to the disk center. Our analysis is based on a sequence of nearly diffraction-limited scans of the Fe i 617.3nm line taken with the CRisp Imaging Spectro-Polarimeter instrument at the Swedish 1 m Solar Telescope. We compute Dopplergrams from the observed intensity profiles using line bisectors and filter the resulting velocity maps for subsonic oscillations. Lateral downflows appear everywhere in the center-side penumbra as small, weak patches of redshifts next to or along the edges of blueshifted flow channels. These patches have an intermittent life and undergo mergings and fragmentations quite frequently. The lateral downflows move together with the hosting filaments and react to their shape variations, very much resembling the evolution of granular convection in the quiet Sun. There is a good relation between brightness and velocity in the center-side penumbra, with downflows being darker than upflows on average, which is again reminiscent of quiet Sun convection. These results point to the existence of overturning convection in sunspot penumbrae, with elongated cells forming filaments where the flow is upward but very inclined, and weak lateral downward flows. In general, the circular polarization profiles emerging from the lateral downflows do not show sign reversals, although sometimes we detect three-lobed profiles that are suggestive of opposite magnetic polarities in the pixel.Financial support by the Spanish Ministerio de Economia y Competitividad through grants AYA2009-14105-C06-06, AYA2012-39636-C06-05, and ESP2013-47349-C6-1 R, including a percentage from European FEDER funds, is gratefully acknowledged.Peer Reviewe

Presentación
[ES] La violencia ha sido considerada uno de los grandes ejes que explican el devenir de la humanidad desde los comienzos de la ciencia historiográfica. Nos repele y nos atrae, deseamos olvidarla pero no debemos dejar que caiga en el olvido, aparenta estar ligada a momentos históricos concretos pero atraviesa nuestro día a día… Quizás por estas razones la violencia, en todas sus posibles manifestaciones, lejos de ser un tema obsoleto, continúa teniendo un gran potencial como cuestión historiográfica, tal y como muestran las investigaciones que conforman este libro.
De la mano de diferentes especialistas, y en un recorrido que va desde la Prehistoria hasta la Edad Contemporánea, este volumen colectivo analiza las violencias históricas desde la antropología física, la historia militar, la iconografía, o la historia de la infancia entre otros puntos de vista. Guerras, conflictos políticos y religiosos y sus significados simbólicos, o la violencia como espectáculo son algunas de las cuestiones que abordan sus páginas.
Si bien existen pocos temas que hayan sido más estudiados por la historiografía que la violencia, este libro, fruto del Congreso Internacional La Violencia en la Historia, celebrado en la Universidad de Salamanca en octubre de 2019, es una muestra de que las preguntas históricas nunca se agotan y de que las violencias pasadas deben seguir siendo revisitadas desde nuevos enfoques
La influencia del empleo atípico en los trabajadores
Con el paso de los años el empleo atípico se ha ido abriendo camino en el mercado laboral hasta llegar a representar una parte importante del empleo total global. Aunque el aumento de este tipo de empleo ha permitido una mayor flexibilidad, también ha dado lugar a una gran inseguridad tanto para los trabajadores como para las empresas, los mercados laborales, las economías y las sociedades. Por ello surge la necesidad de estudiar cuáles son los factores que lo potencian, así como los colectivos más afectados. En este trabajo se intentará analizar dicha información a través de datos obtenidos por fuentes oficiales, centrándose en la temporalidad en España, y en los riesgos psicosociales a los que se exponen los trabajadores, los cuales se han agravado debido al COVID-19 y a las consecuencias que esta pandemia ha dado lugar.Grado en Relaciones Laborales y Recursos Humano
