En el año 2011, en torno al movimiento 15M, miles de españoles se conectaron a Twitter para convocarse, organizarse y gestionar encuentros en plazas públicas, para protestar por el detrimento progresivo de su estado de bienestar social. Esta investigación, de enfoque cuantitativo, se propuso identificar las tendencias en los temas de interés en 17.599 tuis publicados por la red de conexiones de 14 usuarios vinculados al movimiento 15M y su relación con la estructura de la red de comunicación que emergió de estos tuits. Para identificar la estructura de dicha red se usó el método de Análisis de Redes Sociales (ARS) usando NodeXL. Para detectar las tendencias de los temas de interés, se aplicaron técnicas de minería de texto, usando Excel y T-Lab. Se encontró que Twitter jugó un importante papel en la difusión de la información, en las convocatorias y en la organización del movimiento 15M; las tendencias en los hashtags estaban orientadas a visibilizar el movimiento y a invitar a las actividades programadas, y las de los lemas a organización (Asamblea, seguir, gente, democracia) y a espacios físicos (calle, plaza). Finalmente, se encontró una relación directa entre las métricas de la red y las tendencias de los temas de interés.

This quantitative research set out to identify trends in the topics of interest of a corpus of 17,599 tweets published by the network of connections of 14 organizational platforms, local and civic groups linked to the 15M movement as well as their relationship with the structure of the communication network that emerged from those tweets. To study the structure of the said network we used the Social Network Analysis (SNA) and the program NodeXL. In order to detect the trends in the topics of interest, we applied text mining with Excel and T-Lab. The research showed that Twitter played an important role in spreading the information, convening the meetings and organizing the 15M movement. The trends in the hashtags pointed toward making the movement visible and inviting to the activities; those in the lemmas, to the organization (Asamblea, follow, people, democracy) as well as to gathering places (street, square). Finally, the research revealed a direct relationship between the metrics of the network and the trends in the topics of interest.

Nació en Asunción el 30 de julio de 1.916, hijo del Dr. J. Isidro Ramírez y de Anita Böettner. En 1.934 inicia la carrera de Medicina en Santiago de Chile, pero interrumpe sus estudios al llamado de la patria para participar de la contienda bélica que se iniciaba en defensa del Chaco. Es alistado en el servicio de la Sanidad Militar de donde es evacuado gravemente enfermo, pero retorna al Chaco casi a fines de 1.935 donde permanece hasta el final de la guerra. De vuelta a Asunción ingresa a la Facultad de Ciencias Medicas de la Universidad Nacional de Asunción, pero pronto se traslada a la Argentina donde es graduado de médico en la Universidad de Buenos Aires, con honores, en el año 1.941.

El presente artículo trata de indagar en una cuestión poco investigada acerca de la personalidad de María Rosa Oliver: su compromiso político a la par de su compromiso estético. La coincidencia de su trayectoria con aquella recorrida por Victoria Ocampo permite contrastar las actividades de estas dos femmes de lettres, especialmente en lo que respecta a la profundidad de los ideales de Oliver frente a cierta banalidad de las expresiones políticas (y quizás también estéticas) de la directora de la revista Sur. El gran momento de tensión de la Guerra Fría que María Rosa Oliver presenció desde un lugar destacado de la agenda política, permite, también, considerar lo que sus intentos de producir un entendimiento entre los pueblos no pudieron lograr. El desmoronamiento de la URSS en 1991 produjo un cambio en el equilibrio internacional que María Rosa Oliver, desde su mentalidad utópica, no podría haber vislumbrado ni aceptado. La sensación que deja su accionar es, por ello, sumamente paradójica y quizás patética si se considera su figura de mujer de la periferia y minusválida luchando contra las fuerzas de Goliat. ; The present article pretends to focus on a question that has not been enough treated in the case of María Rosa Oliver´s personality; I mean: her political commitment that ran together with her aesthetical commitment. The coincidence of her itinerary with the one described by Victoria Ocampo allows to consider the activities of these two femmes de lettres in contrast, especially in what we can call the profundity of ideals by María Rosa Oliver, in front of certain banality in the questions of political considerations (but also may be in her aesthetical reasons) by the director of the Sur magazine. The great period of tension of the Cold War that has found María Rosa Oliver occupying an active and central place permits us to consider now how vain had been her purposes to produce some possibility of a people understanding. The crumbling down of the Soviet Union in 1991 has produced a change in the international balance which María Rosa Oliver, thanks to her utopic mind, would not have foreseen and nor less accepted. The feeling that her activities would leave to us is, therefore, are somehow paradoxical and also, may be, pathetical, if you consider her profile as a woman from the periphery of the world and as a minus-valid fighting against Goliath's forces. ; Facultad de Humanidades y Ciencias de la Educación

Expanding the functionalities of plasmon-assisted lasers is essential for emergent applications in nanoscience and nanotechnology. Here, we report on a novel ability of plasmonic structures to induce dual-wavelength lasing in the near-infrared region in a Yb 3+ solid-state laser. By means of the effects of disordered plasmonic networks deposited on the surface of a Yb 3+ -doped nonlinear RTP crystal, room-temperature dual-wavelength lasing, with a frequency difference between the lines in the THz range, is realized. The dual-wavelength laser is produced by the simultaneous activation of two lasing channels, namely, an electronic- and a phonon-terminated laser transition. The latter is enabled by the out-of-plane field components that are generated by the plasmonic structures, which excite specific Raman modes. Additionally, multiline radiation at three different wavelengths is demonstrated in the visible spectral region via two self-frequency conversion processes, which occur in the vicinities of the plasmonic structures. The results demonstrate the potential of plasmonic nanostructures for inducing drastic modifications in the operational mode of a solid-state laser and hold promise for applications in a variety of fields, including multiplexing, precise spectroscopies, and THz radiation generation via a simple and cost-effective procedure ; L.S.-G., M.O.R., and L.E.B. gratefully acknowledge support from the Spanish Government under project MAT2016-76106-R and Comunidad de Madrid under grant S2013/MIT-2740.

OBJECTIVE. Evaluate the sustainability of the Healthy Municipalities strategy in Guatemala in order to have solid evidence to support decision-making. METHODS. A concurrent mixed-methods study was carried out in five phases: 1) theoretical-conceptual (based on a narrative review of the literature on sustainability, dimensions and categories were proposed for evaluation); 2) empirical (four municipalities were selected for convenience and 29 semi-structured interviews and four focus groups were conducted with key actors to explore sustainability; with this information, a score was assigned to each category and dimension); 3) analytical, by category and dimension (content analysis was performed for qualitative information, and totals and averages were calculated for quantitative information); 4) integrative (qualitative data were integrated into matrices by category and dimension, and quantitative data were supported by qualitative information); and 5) meta-inference (consideration was given to the context and its influence on the results). RESULTS. Ninety-two (92) informants participated. In operational terms, progress was observed in the transfer and use of results, and in rotations in leadership. In the legal and political sphere, accountability and local planning were highlighted. In the economic sphere, progressive investment in health, water and sanitation was emphasized, as well as insufficient investment in social determinants of health. In the social sphere, few mechanisms were observed to promote and strengthen social participation. CONCLUSIONS. In the municipalities that participated in the study, a fair level of sustainability was observed in the Healthy Municipalities strategy.
