A new species of Nidalia Gray, 1835 from Mid-Atlantic seamounts (Octocorallia, Alcyonacea, Nidaliidae)

A new soft coral species of the genus Nidalia, from seamounts to the south of the Azores Archipelago is described. The main features of Nidalia aurantia n. sp. are as following: colony torch-like, a capitulum light orange in colour, not laterally Xattened, dome-shaped and not distinctly projecting beyond the stalk, an introvert with sparse sclerites transversally placed, and an anthocodial crown with 13–17 sclerite rows. The new species is compared with its closest congeners. This is the Wrst time that a species of Nidalia has been located in the Mid-Atlantic Ocean

Seasonal Variation of Essential Oil Yield and Composition of Sage (Salvia officinalis L.) Grown in Castilla - La Mancha (Central Spain)

Links between phenology, yield and composition of the essential oil of common sage, Salvia officinalis L., grown in Guadalajara (Central Spain) were determined in the different phases of the biological cycle during one year. Data showed an average yield about 1.0%. The analysis of the oil components was carried out by GC-FID and GC/MS. The main oil constituent was alpha thujone (40.1 - 46.5%). Other identified compounds are beta pinene (2.6 - 4.5%), cineole (3.5 - 8.7%), beta thujone (4.1 - 5.6%), camphor (4.1 - 8.0%), borneol (1.3 - 3.7%), alpha humulene (3.8 - 7.3%), viridiflorol (3.4-12.6%) and manool (0.1-4.5%). The highest yield of oil was obtained in the period of full flowering and the highest concentration of alpha thujone in the period of initial flowering

Distributed multivariate regression with unknown noise covariance in the presence of outliers: an MDL approach

We consider the problem of estimating the coefficients in a multivariable linear model by means of a wireless sensor network which may be affected by anomalous measurements. The noise covariance matrices at the different sensors are assumed unknown. Treating outlying samples, and their support, as additional nuisance parameters, the Maximum Likelihood estimate is investigated, with the number of outliers being estimated according to the Minimum Description Length principle. A distributed implementation based on iterative consensus techniques is then proposed, and it is shown effective for managing outliers in the data.Peer ReviewedPostprint (author's final draft

Teaching methodology and educational technology in the development of cognitive competences: implementation in university contexts

This research analyses different methodological strategies and techniques involving the use of Educational Technology from a consistent educational approach with a development of cognitivecompetences. The method arises from a descriptive analysis and a factor analysis with a questionnaire with 2 dimensions as an instrument. The sample of 121 students from 2 Spanish universities value positively the application of collaborative learning and integration of Educational Technology with all its possibilities even though they mostly prefer classroomteaching than e-learning. In this sense, we conclude that there are very positive appreciations about the different methodological strategies and techniques that enhance active and collaborative approach involving the development of cognitive competences and based on the concept of learning by doing

El proyecto morfogen. Diseño de una aplicación web para visualizar familias léxicas

This paper shows the characteristics of a web application designed to represent the family relationships between components of a word family in Spanish (bdme.usc.es). The application consists of two modules: a) a morphological database of Spanish and b) a visualization tool. Different formulations of the concept of ‘word family’ will be shown, as well as some procedures that have been used in other projects in order to account for morpho-lexical relationships. The convenience of a historical approach to word families will be discussed, as well as the appropriateness of working with two types of family relationships: (i) the one associating a word with its origin and (ii) the one associating the word with its lexical base. Some issues that emerged during the process of conversion from a single-user to a multiple-access database will be discussed. The main features of the database will be explained. The design of two representational forms (tree and linear diagrams) will be shown: the former aims to produce a global representation of a word family while the latter seeks to represent the progression of derivational processes in the series of a given language.El objetivo de esta contribución es presentar las características de una aplicación web destinada a hacer visibles en español las relaciones de parentesco entre las palabras de una misma familia léxica (bdme.usc.es). La aplicación contiene dos módulos: a) una base de datos de morfología del español y b) una herramienta de visualización. En este trabajo se mostrarán diferentes concepciones de la noción de familia léxica y también algunos procedimientos empleados en otros proyectos para dar cuenta de relaciones morfoléxicas. Se mostrará la conveniencia de aplicar un enfoque histórico a las familias léxicas y de trabajar con dos tipos de relaciones de parentesco: (i) la que asocia una palabra con su origen y (ii) la que vincula una palabra con su base léxica. Se comentarán algunos problemas surgidos durante el proceso de conversión de una base de datos monousuario en otra de acceso compartido. Se explicarán las principales características técnicas de la base de datos y se mostrará el diseño de dos formas de representación: en diagramas arbóreos y en forma lineal. Con la primera se pretende ofrecer una imagen global de cada familia léxica y con la segunda se busca reflejar la progresión de los procesos derivativos en las series de una misma lengua

Las Kellys and tourism: from the invisibility of care to political visibility

The work done by the Kellys, or apartment waitresses/cleaners, is characterised by it lying in what could be called “care work”, despite being completely undertaken in the production field and forming a vital part of the tourism sector. Their case is a clear example of the intersection between precarious work and the invisibility of some tasks that have been historically and culturally appointed to women and condemned to social scorn. In today’s context, it is worth considering the social conditions underlying this group of workers and the implications that stem from their situation of invisibility in such a precarious sector as the tourism one in the Spanish State, and the role played by the Kellys, as an association, to claim these female workers’ employment rights. We will analyse their particular case as a clear example of the socio-political movement that struggles to make their care work visible and contributes to the repoliticisation of their work in the public domain.El trabajo desarrollado por las kellys o camareras de piso se caracteriza por encontrarse dentro de lo que se podría denominar como «trabajo de cuidados», aunque se inscribe de lleno en el campo productivo y es una parte vital del sector turístico. Su caso es un claro ejemplo de la intersección entre la precariedad y la invisibilidad de unas tareas que han sido histórica y culturalmente asignadas a las mujeres y condenadas al menosprecio social. En un contexto como el actual, cabe preguntarse sobre las condiciones sociales que subyacen a este colectivo y las implicaciones que se derivan de su situación de invisibilidad en un sector tan precario como el turístico dentro del Estado español, así como sobre el papel de Las Kellys –como asociación– en la reivindicación de los derechos laborales de las trabajadoras. Analizaremos su caso como una muestra de movimiento político y social que lucha por la visibilización de las tareas de cuidados y que contribuye a la repolitización de dichos trabajos en el ámbito público

Colour morph does not predict brood size in the Booted Eagle.

Mechanisms regulating colour polymorphism remain largely unknown and detailed investigation is required to explore the biological consequences on population dynamics. This paper presents the first study of the possible connection between colour polymorphism and productivity in a Booted Eagle (Aquila pennata) population breeding in southeastern Spain. To that end we used 19 years of data of non-marked individuals. A total of 738 pale (91.6%) and 68 dark (8.4%) adult Booted Eagles were observed in our study area, including 57 territories. Our results suggest that colour morph of both sexes remained stable in the population over the study period. Although we found a higher number of offspring produced by parents exhibiting the dark morph than those of the pale morph, statistical differences were not significant. Hence, our models showed that colour polymorphism was not a good predictor of Booted Eagles'productivity, although further research by capture-recapture analysis would be needed to explore the influence of colour variation on fitness components at individual level and its consequences at population level of long-lived species

El Poblamiento Ibérico en la comarca de la Serranía (Valencia), ss. VI-I a.C. Aproximación al modelo de ocupación del territorio

Primera hipótesis del modelo de poblamiento ibérico en el centro de la comarca valenciana de la Serranía, un territorio en el que se documentan numerosos yacimientos de esta época aunque, paradójicamente, los trabajos de investigación publicados escasean y las excavaciones arqueológicas han sido casi nulas

Osteonecrosis de los maxilares asociada a bifosfonatos: revisión sistemática

En los últimos años se ha descrito una nueva complicación en la terapia con bifosfonatos: la osteonecrosis de los maxilares. Esta complicación no había sido detectada en los ensayos clínicos previos. En esta revisión sistemática de 340 casos, los pacientes afectados presentan como diagnóstico primario principalmente: mieloma múltiple (51,2%), cáncer de mama (31,4%), cáncer de próstata (7,1%) y osteoporosis (4,1%). La mandíbula resulta más afectada que el maxilar, con el 59,1%. La relación entre género femenino y masculino es de 2:2,6. El pamidronato es el bifosfonato más asociado a los casos de osteonecrosis (35,3%). Los factores de riesgos desencadenantes incluyen: exposición a bifosfonatos, infecciones orales, traumas, procedimientos quirúrgicos orales previos y terapias contra el cáncer (quimioterapia, corticoides y otros agentes citostáticos). La alteración en el equilibrio óseo, factores antiangiogénicos, inhibición en el ciclo celular de los queratinocitos y mecanismos osteolíticos generados en la infección podrían explicar la etiopatogenia en el desarrollo de esta complicación
