El uso de las redes sociales en el fortalecimiento de la comunicación entre líderes y militantes del Rartido Revolucionario Institucional.

El uso de las redes sociales como nuevas tecnologías aplicadas dentro de los sistemas políticos, ha permitido en nuestros días que la comunicación entre gobernantes y gobernados se realice a partir de un enfoque en el que ambos, tengan la facilidad de intercambiar puntos de vista, opiniones o comentarios relacionados al ámbito público. Con ello, la posibilidad de que los resultados derivados de esta forma de comunicarse se concreten en procesos democráticos transparentes, mayor participación de la ciudadanía y mejores tomas de decisiones, sirve para posicionar la actual dinámica de comunicación digital. En México, el uso de las redes sociales como herramienta de comunicación dentro de las instituciones, especialmente en los partidos políticos, es de aplicación reciente, sin embargo, han demostrado a partir de manifestaciones colectivas digitales, que son la plataforma ideal por la que los ciudadanos se expresan sin temor a la censura. La participación de la opinión pública en estas plataformas digitales se da de manera instantánea, pública y masiva, donde la única limitante es no contar con un dispositivo con conexión a Internet. En la actualidad, las instituciones públicas han implementado el manejo de redes sociales como medio de comunicación interna y externa en su organización. En el caso de los partidos políticos, la dinámica va más allá del posicionamiento de la imagen de los candidatos en redes sociales durante la contienda electoral; los partidos han optado por nuevas estrategias para comunicarse entre el liderazgo y la militancia que responden a acciones de movilización y activismo interno

Homicide Profiles Based on Crime Scene and Victim Characteristics

One of the current trends in homicide research includes developing works based on scientific study and empirical evidence, which offer conclusions that can be used in an operational manner during police investigations. The objective of this study was to identify homicide characteristics from behaviors carried out on the crime scene and victim characteristics associated with those of the perpetrators of these crimes in Spain. The sample consisted of 448 homicide cases from the database of the Homicide Revision Project led by the Office of Coordination and Studies of the Secretary of State and Security. After creating six classification tree models, it was found that the modus operandi of the aggressor and the victim characteristics may permit hypothesizing about the demographic characteristics of the perpetrator (gender, age, and country of origin), his/her criminal record, and the type of relationship with the victim. Furthermore, the importance of the study of victimology during a criminal investigation is highlighted, as it may indirectly offer information about the potential perpetrator. The findings of this study suggest that criminal profiling contributes notably to the decision-making process to establish more rigorous suspect prioritization, improve the management of human resources and materials, and increase the efficiency of criminal investigations

Labour status and involuntary employment: family ties and part-time work in Spain

The aim of the paper is a gender analysis of the extent to which parttime work represents an individual’s preferred labor market situation. The work includes a theoretical model that delivers some predictions about the household’s preferences over non-chosen employment states. Furthermore, it explores the impact of individual, family and job related variables on the probabilities of involuntary and voluntary part-time employment in Spain. The main empirical findings of the paper are: first, the model is sensitive to the chosen definition of (voluntary) part-time employment; second, there exist important gender asymmetries in labour market behaviour concerning the importance of the individual’s education and family characteristics; third, the marital status and having small children are important determinants of a woman’s probability of being voluntary part-time employed, whereas having grown up children or a temporary contract increases significantly a woman’s probability of involuntary part-time employment.part-time work, involuntary employment, family ties and labour supply.

Aproximación a la Nueva Babilonia de Constant

El artista holandés Constant Nieuwenhuys, recientemente fallecido, dio forma material a las propuestas de la Internacional Situacionista sobre el urbanismo del futuro con su ciudad utópica, New Babylon. Durante casi veinte años, su proyecto se desarrolló a través de maquetas, dibujos, grabados, collages, etc., así como en una serie de ensayos. En este artículo repasamos las claves de New Babylon y sus relaciones con la crítica urbana situacionista.The Dutch artist Constant Nieuwenhuys, recently deceased, gave substance to the proposals of the International Situationist for the future urbanism through his utopian city, New Babylon. For almost twenty years, his project developed through maquettes, drawings, engravings, collages, etc., as well as several essays. This article revises the key elements of New Babylon and its connections with the situationist urban criticism

Expressiveness and Instrumentality of Crime Scene Behavior in Spanish Homicides

One of the current trends in the study of criminal profiling consists of developing theoretical and methodological typologies to offer information of operational use in police investigations. The objective of this work was to verify the validity of the instrumental/expressive model, so as to establish homicide typologies based on modus operandi relationships, characteristics of the victims, and characteristics of perpetrators. The sample consisted of 448 homicide cases registered in the database of the Homicide Revision Project of the Office of Coordination and Studies of the Spanish Secretary of State and Security. Through multidimensional scaling and cluster analysis, three expressive homicide subtypes were identified (expressive-impulsive, expressive-distancing, and expressive-family), as well as two instrumental homicide subtypes (instrumental-opportunist and instrumental-gratification). The expressive homicide typologies accounted for almost 95% of all of the studied cases, and most of the homicides occurring in Spain were found to take place between individuals who know one another (friends, family members, intimate couples/ex-couples). The findings from this study suggest that the instrumental/expressive model may be a useful framework for understanding the psychological processes underlying homicides, based on the study of relationships between the crime and aggressor characteristics, which may be very helpful in the prioritization of suspect

The effects of context and characteristics of women entrepreneurs on innovation performance

Drawing on institutional and upper echelons theories, this study delves into the underexplored intersection of gender, context, and innovation performance among women entrepreneurs in Ecuador. Based on a sample of 45 women entrepreneurs, the study employs a fuzzy-set qualitative comparative analysis (fsQCA) and identifies six distinct paths to innovation performance. Contrary to initial expectations, our research findings substantiate that both institutional and social factors play a key role in fostering innovation in women-led firms in Ecuador. This innovation is facilitated by establishing close and frequent interpersonal connections, as well as by the age of the female entrepreneurs. Conversely, certain individual variables traditionally associated with innovation, such as education level or prior experience, manifest only sporadically. Our research enriches the discourse in gender and innovation studies by employing a multilevel approach and provides valuable insights into female entrepreneurial leadership’s contribution to advancing developing economies.COMPSOS Project (PID2020-117313RB-I00) funded by MCIN/ AEI/ 10.13039/501100011033SOSTEMPRE Project (B-SEJ-682-UGR20) funded by Consejería de Universidad, Investigación e Innovación (Junta de Andalucía) Programa Operativo FEDER Andalucía 2014-2020Faculty of Economics and Business Administration, University of Granada (Spain

Magnetized, Relativistic Jets

Extragalactic relativistic jets are composed by charged particles and magnetic fields, as inferred from the synchrotron emission that we receive from them. The Larmor radii of the particles propagating along the magnetic field are much smaller than the scales of the problem, providing the necessary coherence to the system to treat is as a flow. We can thus study them using relativistic magnetohydrodynamics. As a first step, we have studied the structure of steady-state configurations of jets by using numerical simulations. We have used a helical field configuration and have changed different relevant parameters that control the way in which the energy flux is distributed in jets (namely, the proportion of the energy flux carried by internal, kinetic or magnetic energy). Our results show significant differences among the different kinds of jets. Finally, we also report on results based on synthetic maps of our simulated jets.Comment: Submitted for publication in Proceedings of Science, as contribution to the proceedings of the XII Multifrequency Behaviour of High Energy Cosmic Sources Workshop, held in Palermo, 12-17 June 201
