El estudio de las interacciones entre los organismos mediadas por sustancias químicas, lo que se denomina ecología química, nos da información sobre la biología de las especies implicadas, el funcionamiento de la comunidad en que viven y nos puede proporcionar además el conocimiento de nuevas sustancias que pueden ser útiles para el ser humano. En el marco de nuestros estudios sobre la ecología química de los invertebrados antárticos, en el proyecto ECOQUIM (2003-2006) se recolectaron numerosas muestras biológicas a partir de las cuales se obtuvieron extractos y sustancias naturales de invertebrados antárticos. En el proyecto ACTIQUIM (2007-actualidad), se ha evaluado el papel ecológico de estos extractos y sustancias naturales mediante experimentos de ecología química in situ (repelencia, defensa ante distintos tipos de macro y micro-depredadores, toxicidad, citotoxicidad y actividad antifouling) y también se ha analizado la actividad antitumoral de algunos compuestos obtenidos recientemente. Nuestros resultados demuestran, entre otras cuestiones, que las defensas químicas en los organismos antárticos son elevadas en las esponjas, los cnidarios, los tunicados, los briozoos, los equinodermos y los moluscos y que por lo tanto, estos grupos pueden ser una fuente rica en metabolitos secundarios con bioactividad, tanto a nivel ecológico como farmacológico.

Tourism is one of the most important sectors in the global economy and is considered an efficient tool with which to promote economic growth. The case of Spain¿s economy is well known in this respect; in fact, widespread consensus exists on the part played by tourism in enhancing the industrialisation process in Spain and the part played by foreign currency receipts from tourism in financing the imports of capital goods, which made the expansion of manufacturing possible. This paper aims to assess the real role of foreign currency receipts from tourism in Spain¿s economy from 1960 to the present. The results of Spain¿s experience may well help to guide policy decisions in developing countries in similar circumstances.

Within the scope of the TECNOLONIAL (HAR2008-02834/HIST) project, an archaeologi- cal and archaeometric research is being conduct- ed in order to clarify and systematize transport jars production in the Iberian peninsula and their distribution abroad, especially to the Americas, from the 15th to the 17th century. The production centre of Seville, in the Crown of Castile, produced large glazed and unglazed transport jars, called botijas, which were mainly devoted to the Atlantic trade network. The pres- ent study accounts for the first results obtained from an initial sample of 34 transport jars dated around the 15th-16th centuries from the produc- tion centre of Seville and the reception site of Santa María de la Antigua del Darién (gulf of Urabá, Colombia). This latter site is especially significant since it was the first Spanish founda- tion (1510) in continental America that obtained the title of town, and was the seat for the Governor of the new region called Castilla de Oro, as well as for the first diocese. All individuals were analyzed by means of x-ray fluorescence and diffraction analyses and then compared with the majolica production database from Seville. The results enabled us to define the first refer- ence groups for such modern transport jars, and to get a first insight into the jars coming to the Americas in the early 16th century whose prove- nance can be linked to Seville, but not Triana.

Introduction: in the present study several collectives with knowledge of the reality of family care of the elderly assessed several socia and healthcare resources and suggested several possibilities for improvement. Method: four discussion groups were used as a data collection technique. The groups were composed of caregivers, representatives-users of associations for the elderly, experts in geriatrics, and social services professionals. Results: the various discussion groups positively evaluated the Home Help Service, the Support Teams of the Home Service Programs, Interdisciplinary Community Health Workers Units, Daytime Care Centres, and the Family Rest Programme but suggested some changes to all of them. The discussion groups also indicated the need to improve the material, economic and emotional assistance given to caregivers and asked for training, institutional coordination, anddissemination of information about available resources and assistance. Conclusions: some changes are required to improve the current social and health resources available to families caring for the elderly within the family unit. Among the suggestions for improvement proposed by the participants, many are useful and could easily be applied, whereas others provide an interesting starting point for debate and reflection. Knowledge and understanding of the situation of caregiving families, based on their own experiences and those of the people who know them, is in itself sufficient to initiate and implement changes to provide resources appropriate to their needs

En el presente artículo hemos tratado de analizar las características de las almazaras cooperativas catalanas con la finalidad de destacar no solamente sus elementos más importantes de gestión sino también sus principales debilidades. Las cooperativas se consideran instrumentos útiles para acometer políticas de desarrollo económico y bienestar social. A pesar de ello hay un gran debate abierto acerca de la eficiencia de estas organizaciones, que plantean el interrogante de si están en condiciones de competir con éxito en una economía cada vez más abierta, liberalizada y global. A través de las encuestas que hemos realizado al conjunto de las cooperativas oleícolas de Catalunya, hemos podido averiguar sus características distintivas, así como las principales desventajas y problemas a los que se enfrentan. Creemos puede ser de interés analizar las características de estas organizaciones, que tanto desde el punto de vista organizativo como de recursos humanos, como financiero, las hace diferentes de otro tipo de organizaciones pero que sin embargo, han de hacer frente a un mercado cada día más exigente y competitivo

El objetivo de este trabajo es motivar al profesorado para que en las evaluaciones de sus alumnos y alumnas tenga en cuenta la metacognición como factor fundamental en el aprendizaje y la enseñanza. Es importante plantear la evaluación como una recapitulación de los aprendizajes y una situación para aplicar destrezas de autorregulación metacognitiva, ya que éstas en un futuro pueden resultar útiles en diversos contextos
