La enseñanza universitaria vista por alumnos y empresarios en el marco del cambio social actual

La presente ponencia analiza la adecuación de las enseñanzas universitarias a los actuales requerimientos de la realidad empresarial tanto desde el punto de vista de los propios alumnos como desde el de los empresarios. Con ello se pretende constatar la existencia de nuevas motivaciones para acceder a una formación universitaria, así como de distintas expectativas de futuro una vez lograda ésta, derivadas de los cambios psico-sociológicos que se vienen produciendo en los últimos tiempos. Para ello se ha llevado a cabo un estudio empírico-descriptivo sobre el alumnado, completado con otro de características similares realizado con anterioridad sobre una muestra representativa de empresarios

Straightforward access to bisbenzamidine DNA binders and their use as versatile adaptors for DNA-promoted processes

Bisbenzamidines are an important family of minor groove DNA-binding agents. We present a one-step synthesis of aromatic aza-bisbenzamidines that allows straightforward and versatile access to a large number of these molecules. One of them, the azide-aza-bisbenzamidine 13, can be readily modified via click-chemistry with a variety of functionalities that can, therefore, be delivered to the vicinity of an A/T-rich DNA minor groove. This strategy, therefore, provides a simple means for triggering site selective, DNA-promoted biochemical and physicochemical processesS

Quality in Blended Learning in Higher Education. A proposal for an Evaluation Model.

This paper presents an analysis of different models used to assess the quality of formative actions, considering classroom learning and distance education courses. Taking as starting point one of the analyzed models, the paper sets out the necessity of developing a new model that could measure the quality of a blended formation process, by selecting the applicable indicators and proposing some new. The model is composed of seven different categories, which include a sum of thirty five indicators. They will be used to represent courses quality level in Kiviat?s diagrams. This model is currently being put into practice in a real university environment

Tutores de resiliencia y adopción. Una propuesta desde el modelo de Traumaterapia sistémica infanto-juvenil de Barudy y Dantagnan

No todos los niños y niñas tienen la oportunidad de crecer en contextos bientratantes. Cuando, como ocurre en la mayoría de las adopciones, no ha sido posible la permanencia de un tutor de desarrollo capaz de brindar al niño o niña los cuidados necesarios para su bienestar y que pueda emerger así la resiliencia primaria, es posible, gracias al apoyo de tutores de resiliencia, ofrecer oportunidades de seguridad y afecto que posibiliten la reparación de traumas y la revinculación afectiva. El Modelo de Traumaterapia sistémica infanto-juvenil de Barudy y Dantagnan ofrece un marco de actuaciones tratando de dar respuesta, desde un paradigma biopsicosocial, a las necesidades que niños, niñas y adolescentes adoptados presentan, especialmente cuando han sufrido experiencias tempranas adversas y prolongadas como malos tratos, negligencia y/o abuso sexual. En el presente artículo se ofrece una aproximación al concepto de tutor de resiliencia y se describe brevemente el citado modelo.Not all children could grow up in nurturing contexts. When, as is the case in most adoptions, it has not been possible to have a developmental mentoring capable of providing the child with the care necessary for his or her well-being in order to emerge the basic resilience, it is possible, thanks to the support of resilience mentors, to offer opportunities for safety and affection that enable trauma repair and bonding. Barudy and Dantagnan's Systemic Child and Adolescent Traumatherapy Model offers a framework of actions trying to respond, from a biopsychosocial paradigm, to the needs that adopted children and adolescents present, especially when they have suffered adverse and prolonged early experiences such as maltreatment, neglect and/or sexual abuse. This article offers an approach to the concept of resilience mentoring and briefly describes the aforementioned model

Copépodos (Crustacea: Copepoda) como agentes de control biológico de larvas de mosquitos Aedes (Diptera: Culicidae) en Chiapas, México

We identified species of copepods in natural mosquito breeding sites in the region of Soconusco, Chiapas, Mexico and compared their predatory ability on first instar larvae of Aedes aegypti and A. albopictus. Four sampling sites were selected: two in the coastal area and two in the bottom of the mountain. Copepods were cultured in the laboratory and identified. The species found were: Mesocyclops pehpeiensis (Hu, 1943), M. longisetus (Thiébaud, 1912), M. brasilianus (Kiefer, 1933), Macrocyclops albidus (Jurine, 1820), Eucyclops leptacanthus (Kiefer, 1956), and E. torresphilipi (Suárez-Morales, 2004). With the exception of E. leptacanthus, all collected species of copepods were successfully cultured in the laboratory. The predation potential was experimentally evaluated using a copepod female adult and 20 first-instar mosquito larvae. The copepod species showed varying percentages of predation, M. pehpeiensis being the one with the greatest predation potential (80% of A. aegypti and 67% A. albopictus per day). Eucyclops torresphilipi showed no differences with respect to the control, so it can be considered as a non-predatory species. Predation tests show that the copepods present in natural mosquito breeding sites have the potential to be used as agents of biological control of mosquito larvae and are a good alternative to be considered in integrated vector management strategies of dengue fever in the region of Soconusco, State of Chiapas, Mexico.Se identificaron las especies de copépodos presentes en sitios de crianza de mosquitos en la región del Soconusco, Chiapas, México, y se evaluó su capacidad depredadora sobre larvas de primer estadio de mosquitos Aedes aegypti y A. albopictus. Se seleccionaron cuatro sitios de muestreo: dos en la zona costera y dos en una zona al pie de montaña. Los copépodos fueron cultivados en el laboratorio e identificados. Las especies encontradas fueron: Mesocyclops pehpeiensis (Hu, 1943), M. longisetus (Thiébaud, 1912), M. brasilianus (Kiefer, 1933), Macrocyclops albidus (Jurine, 1820), Eucyclops leptacanthus (Kiefer, 1956) y E. torresphilipi (Suárez-Morales, 2004). Con excepción de E. leptacanthus,todas las especies de copépodos colectadas fueron cultivadas con éxito en el laboratorio. Experimentalmente se evaluó el potencial de depredación de las especies, usando un copépodo adulto hembra y 20 larvas de mosquitos de primer estadio. Las especies de copépodos presentaron porcentajes variables de depredación, siendo M. pehpeiensis la especie con mayor potencial de depredación (80% con A. aegypti y 67% con A. albopictus, por día). Eucyclops torresphilipi no mostró diferencias con respecto al control, por lo que puede considerarse como no depredadora. Las pruebas de depredación mostraron que los copépodos presentes en los sitios de crianza de larvas de mosquitos tienen potencial para usarse como agentes de control biológico, y que son una buena alternativa a considerar dentro de las estrategias de manejo integrado de vectores del dengue en la región del Soconusco, Chiapas, México

MitoBlue: A Nontoxic and Photostable Blue-Emitting Dye That Selectively Labels Functional Mitochondria

We report the discovery of a fluorogenic dye, N1,N3-di(2-aminidonaphthalen-6-yl) propane-1,3-diamine, MitoBlue, which selectively stains functional mitochondria while displaying low toxicity, bright blue emission, and high resistance to photobleaching. Additionally, we show that a biotin-labeled MitoBlue derivative can be used as a handle for the delivery of streptavidin-tagged species to the mitochondriaWe are thankful for the support given by the Spanish grants SAF2013-41943-R, CTQ2012-31341, and BFU2013-43513-R, the Xunta de Galicia, GRC2013-041, the ERDF and the European Research Council (Advanced Grant Na 340055).

Gendered management in Spanish universities: functional segregation among vice-rectors

The reorganisation of higher education according to the marketplace logic – and framed within the process of Europeanisation and globalisation – has run parallel to a significant rise in the number of women in senior management positions at Spanish universities. This would seem to be a step to more gender equality. However, the analysis of the situation used thus far, based on conventional indicators, may be harbouring a not-so-egalitarian reality. Our approach studies the gender distribution of vice-rectors according to assigned functions in all forty-eight Spanish public universities offering both graduate and postgraduate studies. It does so by creating a typology to exemplify gendered divisions of labour within those positions. The results confirm an uneven gender distribution: women, although mostly in charge of caregiving and housekeeping functions, are underrepresented across the board in areas where strategic power resides and the future of university is decided and where, eventually, gender norms could be changed.Depto. de Sociología AplicadaFac. de Ciencias Políticas y SociologíaTRUEpu

Haplosporidium pinnae Parasite Detection in Seawater Samples

In this study, we investigated the presence of the parasite Haplosporidium pinnae, which is a pathogen for the bivalve Pinna nobilis, in water samples from different environments. Fifteen mantle samples of P. nobilis infected by H. pinnae were used to characterize the ribosomal unit of this parasite. The obtained sequences were employed to develop a method for eDNA detection of H. pinnae. We collected 56 water samples (from aquaria, open sea and sanctuaries) for testing the methodology. In this work, we developed three different PCRs generating amplicons of different lengths to determine the level of degradation of the DNA, since the status of H. pinnae in water and, therefore, its infectious capacity are unknown. The results showed the ability of the method to detect H. pinnae in sea waters from different areas persistent in the environment but with different degrees of DNA fragmentation. This developed method offers a new tool for preventive analysis for monitoring areas and to better understand the life cycle and the spread of this parasite.info:eu-repo/semantics/publishedVersio

La creatividad en la construcción de campos de sentido

En medio del rediseño del mundo y de todos sus sistemas se está presenciando el mayor movimiento de masas de personas, bienes, fábricas, finanzas frenéticas e ideas en la historia. Los grandes flujos hacen que la nueva norma sea nómada. Sin embargo, persiste un anhelo de pertenencia, distinción e identidad que se resiste al fenómeno “cualquier momento y en cualquier lugar” habilitado por la digitalización, que está cambiando la forma en que interactuamos con el espacio, el lugar y el tiempo. Las viejas certezas se están desmoronando y los sistemas se están rompiendo a una velocidad creciente. La preocupación está latente cuando inventamos un tipo diferente de ciudad. Pero es en este escenario, donde es la ciudad cívica, la comunidad creativa, la que trata de encontrar un camino a través de las principales fallas, dilemas y potenciales de nuestro tiempo: vidas compartidas, desigualdad, angustia ambiental y vitalidad urbana. Este es el lugar donde en palabras de Gabriel (2013, 2015) emerge un campo de sentido, reinventamos el anclaje, un espacio común urbano, la conexión, pero también la posibilidad y la inspiración. La creatividad es una fuente de desarrollo integral del territorio. Reconocer y promover la comunidad creativa y su valor identitario es asegurar la calidad de vida y el desarrollo ambiental sustentable; cultural, social y económico. Esta investigación se dirige a examinar el enfoque de ciudades creativas, y la perspectiva emergente de las comunidades creativas. Se discute la coexistencia de ambas tendencias y sus implicancias para el mejoramiento de la calidad de vida y en la construcción de la sustentabilidad ambiental urbana

Sample selection via clustering to construct support vector-like classifiers

This paper explores the possibility of constructing RBF classifiers which, somewhat like support vector machines, use a reduced number of samples as centroids, by means of selecting samples in a direct way. Because sample selection is viewed as a hard computational problem, this selection is done after a previous vector quantization: this way obtaining also other similar machines using centroids selected from those that are learned in a supervised manner. Several forms of designing these machines are considered, in particular with respect to sample selection; as well as some different criteria to train them. Simulation results for well-known classification problems show very good performance of the corresponding designs, improving that of support vector machines and reducing substantially their number of units. This shows that our interest in selecting samples (or centroids) in an efficient manner is justified. Many new research avenues appear from these experiments and discussions, as suggested in our conclusions.Publicad
