Detection of infalling hydrogen in transfer between the interacting galaxies NGC 5426 and NGC 5427

Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot spectrometer, produced maps of the two galaxies in Halpha surface brightness and radial velocity. We found emission with the range of velocities associated with NGC 5426 along lines of sight apparently emanating from NGC 5427, superposed on the velocity map of the latter. After excluding instrumental effects we assign the anomalous emission to gas pulled from NGC 5426 during its passage close to NGC 5427. Its distribution, more intense between the arms and just outside the disk of NGC 5427, and weak, or absent, in the arms, suggests that the infalling gas is behind the disk., ionized by Lyman continuum photons escaping from NGC 5427. Modeling this, we estimate the distances of these gas clouds- behind the plane: a few hundred pc to a few kpc. We also estimate the mass of the infalling (ionized plus neutral) gas, finding an infall rate of 10 solar masses per year, consistent with the high measured SFR across the disk of NGC 5427 and with the detected circumnuclear galactic wind.Comment: 10 pages, 4 figures.

“Aproximación al concepto de organización criminal e injusto sistémico”

This research paper shows the problems and difficulties in determining a concept of criminal organization. The starting point is the Spanish legal framework and the civil criminal dogmatic. In this way it seeks to know and identify the implications and scope of the criminal organization, due to its negative impact on current societies. Keywords: Autopoiesis. Normative concept. Conclusions. Criminal structure. Systemic unfair. How to reference this article: Zurita Gutiérrez, A. (2019). “Aproximación al concepto de organización criminal e injusto sistémico”.

Usos y resultados de las redes sociales como estrategia electoral: análisis del caso de cuatro municipios del gran Concepción (Chile) en la campaña de 2016

The process of disaffection in the political activity in Chile and the legal amendments to the electoral propaganda and the financing of campaigns in the country generated that parties and candidates could see social networks as an opportunity of dissemination and adverti- sing through the Internet. However, the practice shows that, despite its manifest importance, the activity has not reached an edge of professionalization yet. This explanatory research depicts the use of digital platforms specifically in four Chilean cities during the 2016 munici- pal election. Based on that information, there will be a critical reflection on the role of the journalist and social communicator in the design of relevant communication strategies in the electoral activity.El proceso de desafección que vive la actividad política en Chile y las modificaciones legales realizadas a la propaganda electoral y al financiamiento de las campañas en el país, generó que partidos y candidatos vieran en las redes sociales una oportunidad de difusión y propa- ganda a través de Internet. Sin embargo, la práctica demuestra que, pese a su trascenden- cia manifiesta, la actividad aún no exhibe ribetes de profesionalización. Esta investigación de carácter explicativo grafica el uso de las plataformas digitales específicamente en cuatro ciudades chilenas en la elección municipal de 2016, para a partir de allí, generar una reflexión crítica en torno al rol del periodista y comunicador social en el diseño de estrategias comuni- cacionales pertinentes en la actividad electoral

Validation and Psychometric Properties of the Gameplay-Scale for Educative Video Games in Spanish Children

The knowledge of evaluation instruments to determine the level of gameplay of schoolchildren is very important at this time. A systematic review has been carried out in this study. The aim of this paper is to investigate the psychometric properties of a study of a sample of Spanish gamers. Two hundred and thirty-seven children (mean age: 11.2 +/- 1.17 years, range: 10-12 years, 59.5% female) completed the Gameplay-Scale to discover their opinions after a game session with a serious educational game. The final scale consisted of three factors. The fit for factor 1 (usability) was 0.712, the fit for factor 2 was 0.702 (satisfaction), the fit for factor 3 was 0.886 (empathy) and the overall fit was 0.868. A positive and direct relationship could be observed between all the dimensions of the developed scale. The greatest correlation strength is shown between satisfaction and empathy (r = 0.800; p < 0.005), followed by satisfaction and usability (r = 0.180; p < 0.05) and the association between empathy and usability (r = 0.140; p < 0.05). In summary, the results of the present study support the use of the Gameplay-Scale as a valid and reliable measure of the game experience of youth populations. These results demonstrate strong psychometric properties so that the Gameplay-Scale appears to be a valid instrument for children in different contexts where an educational video game is used, analyzing its usability/“playability” in terms of learning to use it, game satisfaction, and empathy.This research is supported by the Andalusian Research Program under the project P11-TIC-7486 co-funded by FEDER, together with TIN2014-56494-C4-3-P and TEC2015-68752 from the Spanish Ministry of Economy and Competitiveness and FEDER also

Emotional Intelligence, Motivational Climate and Levels of Anxiety in Athletes from Different Categories of Sports: Analysis through Structural Equations

(1) Background: Psychological factors can strongly affect the athletes’ performance. Therefore, currently the role of the sports psychologist is particularly relevant, being in charge of training the athlete’s psychological factors. This study aims at analysing the connections between motivational climate in sport, anxiety and emotional intelligence depending on the type of sport practised (individual/team) by means of a multigroup structural equations analysis. (2) 372 semi-professional Spanish athletes took part in this investigation, analysing motivational climate (PMCSQ-2), emotional intelligence (SSRI) and levels of anxiety (STAI). A model of multigroup structural equations was carried out which fitted accordingly (χ2= 586.77; df = 6.37; р < 0.001; Comparative Fit Index (CFI) = -0.951; Normed Fit Index (NFI) = -0.938; Incremental Fit Index (IFI) = 0.947; Root Mean Square Error of Approximation (RMSEA) = 0.069). (3) Results: A negative and direct connection has been found between ego oriented climate and task oriented climate, which is stronger and more differentiated in team sports. The most influential indicator in ego oriented climate is intra-group rivalry, exerting greater influence in individual sports. For task-oriented climate the strongest indicator is having an important role in individual sports, while in team sports it is cooperative learning. Emotional intelligence dimensions correlate more strongly in team sports than in individual sports. In addition, there was a negative and indirect relation between task oriented climate and trait-anxiety in both categories of sports. (4) Conclusions: This study shows how the task-oriented motivational climate or certain levels of emotional intelligence can act preventively in the face of anxiety states in athletes. Therefore, the development of these psychological factors could prevent anxiety states and improve performance in athletes
