Authors: Belando-Montoro María Remedios 
Published: July 2019

El aprendizaje a lo largo de la vida es considerado uno de los principales objetivos de los organismos supranacionales y de las diversas administraciones educativas nacionales desde hace varias décadas. Este paradigma no es sólo clave para afrontar los problemas mundiales de la educación sino que sus beneficios van más allá, abarcando desde el ámbito laboral al propio desarrollo personal. Sin embargo, y a pesar de la abundante literatura generada al respecto, todavía hoy se hace necesario una visión integradora que aborde los elementos sustanciales de este concepto. Para ello, este artículo parte de las aportaciones generadas por los organismos de la Unión Europea. A continuación, se analiza su desarrollo en España. Se finaliza con la propuesta de una definición del aprendizaje a lo largo de la vida y sus características principales.

Published: July 2019

Education, mainly Islamic based learning, can be found in formal schools, non-formal and informal institutions. A person can freely choose which path to use as a way to take talent and potential in him; even when making formal education, even an individual has the right to participate in non-formal education activities. One of the most appropriate places to forge one's abilities is the campus. It is undeniable that students are one of Indonesia's most influential human resources and are also the next generation of nation-building. Therefore the cadre regeneration function is the most basic. As a generation that must carry out the role of regeneration for the sake of the realisation of the good and happiness of the people, nation and country in the future. Therefore education is needed to help towards the better. Islamic culture has a vital role in the education model that exists in Indonesia. Islamic education is used to improve human morals in a better direction with Islamic methods. It can be observed that student organisations within the campus need a strong foundation to improve their quality in faith and loyalty that has both physical and spiritual intelligence. It is here that the need for Islamic education in helping them is better by the mandate of the national education law.
Pendidikan, terutama pembelajaran berbasis Islam, dapat ditemukan di sekolah formal, lembaga non-formal dan informal. Seseorang dapat dengan bebas memilih jalan mana yang akan digunakan sebagai cara untuk mengambil bakat dan potensi dalam dirinya; bahkan ketika membuat pendidikan formal, bahkan seorang individu memiliki hak untuk berpartisipasi dalam kegiatan pendidikan non-formal. Salah satu tempat paling tepat untuk menempa kemampuan seseorang adalah kampus. Tidak dapat dipungkiri bahwa siswa adalah salah satu sumber daya manusia Indonesia yang paling berpengaruh dan juga merupakan generasi penerus bangsa. Karena itu fungsi regenerasi kader adalah yang paling mendasar. Sebagai generasi yang harus menjalankan peran regenerasi demi terwujudnya kebaikan dan kebahagiaan rakyat, bangsa dan negara di masa depan. Oleh karena itu diperlukan pendidikan untuk membantu menuju yang lebih baik. Budaya Islam memiliki peran penting dalam model pendidikan yang ada di Indonesia. Pendidikan Islam digunakan untuk meningkatkan moral manusia ke arah yang lebih baik dengan metode Islam. Dapat diamati bahwa organisasi mahasiswa di dalam kampus membutuhkan dasar yang kuat untuk meningkatkan kualitas mereka dalam iman dan kesetiaan yang memiliki kecerdasan fisik dan spiritual. Di sinilah perlunya pendidikan Islam dalam membantu mereka lebih baik dengan mandat hukum pendidikan nasional.

Magnetic Sensitivity in the Wing Scattering Polarization Signals of the Hydrogen Lyman-α Line of the Solar Disk Radiation
Authors: Ballester E. Alsina , Belluzzi L. , Bueno J. Trujillo 
Published: July 2019

Abstract
The linear polarization produced by scattering processes in the hydrogen Lyα line of the solar disk radiation is a key observable for probing the chromosphere–corona transition region (TR) and the underlying chromospheric plasma. While the line-center signal encodes information on the magnetic field and the three-dimensional structure of the TR, the sizable scattering polarization signals that the joint action of partial frequency redistribution and J-state interference produce in the Lyα wings have generally been thought to be sensitive only to the thermal structure of the solar atmosphere. Here we show that the wings of the Q/I and U/I scattering polarization profiles of this line are actually sensitive to the presence of chromospheric magnetic fields, with strengths similar to those that produce the Hanle effect in the line core (i.e., between 5 and 100 G, approximately). In spite of the fact that the Zeeman splitting induced by such weak fields is very small compared to the total width of the line, the magneto-optical effects that couple the transfer equations for Stokes Q and U are actually able to produce sizable changes in the Q/I and U/I wings. We find that magnetic fields with longitudinal components larger than 100 G produce an almost complete depolarization of the wings of the Lyα Q/I profiles within a ±5 Å spectral range around the line center, while stronger fields are required for the U/I wing signals to be depolarized to a similar extent. The theoretical results presented here further expand the diagnostic content of the unprecedented spectropolarimetric observations provided by the Chromospheric Lyman-Alpha Spectro-Polarimeter.

Abstract
We report the results of a study designed to test further the basic validity of the seismic models of hot pulsating B subdwarfs that have been developed over the last two decades. Given estimates of the effective temperature, surface gravity, and mass as obtained from a seismic analysis, and given an estimate of the He/H ratio as available from independent spectroscopy, it is possible to compute a “seismic distance” that is suitably corrected for interstellar reddening from a model atmosphere calculation in conjunction with two-band photometry. The test consists of comparing such a distance with that obtained directly from the high-accuracy Gaia parallax measurements that have become available through Data Release 2. Using observed magnitudes in the Gaia G
BP, G
RP bandpasses as well as ground-based photometry in the Johnson B, V, Strömgren b, y, and SDSS g, r filters, we find that all of our seismic estimates fall within 1σ of their parallax counterparts. In addition, the derived reddening for our target stars is shown to be generally consistent with Galactic dust reddening and extinction maps. These results apply to a sample of 14 pulsating hot B subdwarfs for which seismic models were published in the past. We also derive useful constraints on the distances to two more pulsators that belong to unresolved binary systems. The excellent agreement found between seismic and parallax distances for the bulk of the sample adds further credibility to the seismic models that have been calculated for pulsators of this type.
