Arbor : Ciencia, Pensamiento y Cultura , 2009, DOI: 10.3989/arbor.2009.i737.319
Abstract: Key to Nature is a European project that aims to implement digital tools for teaching biodiversity. It involves 14 public and private institutions from 11 European countries, performing different roles, like providing data (Botanical Garden of Madrid, Natural History Museum of London among others), and offering the latest innovations on e-learning (Centre for Usability Research, University of Leuven, Giunti Labs, Italy...) The project, with a 4,8 millions budget half of which is financed by the European Community, lasts three years, the first one just through. Key to Nature es un proyecto europeo que tiene como objetivo la implementación de herramientas digitales para la ense anza de la biodiversidad.

Las asociaciones en las redes personales. Mecanismo de integración de la población inmigrante?
Bolíbar, Mireia
REDES : Revista Hispana para el Análisis de Redes Sociales , 2011,
Abstract: This article aims to present some data about the relational functions that associations have among migrant population. Thus, entails to study the debate that confronts integration and homophily theories. The first ones highlight the virtuous circle of associations and their potential for the development of social capital beyond social groups. Whereas, the second ones consider associations as institutions that reinforce homogeneity on social networks and create parallel structures, creating and reproducing bonding social capital. Both theories are confronted with data of personal networks from the project CASREDIN. The results of this research show direct and indirect effects of participation in associations regarding to the composition of their networks (in terms of origin and place of residence of their Alters) as well as the social support obtained from them. Moreover, differences between various types of association are also explored.
La dispersión geográfica de las redes personales: cálculo y significado.
Molina, José Luis,Bolíbar, Mireia,Cruz, Irene
REDES : Revista Hispana para el Análisis de Redes Sociales , 2011,
Abstract: This article compares three indices that represent the geographical dispersion of personal networks. The first index is built on the computation of distances for each Ego with their Alters and among each one them. After calculating the total distance, it is obtained the average for each Ego. The absolute value of the logarithm of this average is the proposed measure. The second index is constructed taking into account only the relations Ego-Alter of the above formula and the third, common in such studies, shows the distribution of active contacts in a ranking of distances (same neighbourhood, same city, Catalonia, rest of Spain, other countries).The comparison is made exploring the effect of the three indexes on the exchanged social support of people living in Catalonia. The data are taken from the survey of personal networks in the project CASREDIN, interested in exploring social networks and social cohesion in Catalonia. Thus, the resident population divided between "national” and "migrants" and in each of the groups social support is evaluated depending on the geographic dispersion of personal networks. Finally, we propose a discussion of the results within the framework of the theory of "transnationalism".

Apuntes sobre algunos Adenocarpus (Leguminosae) ibéricos
Castroviejo, Santiago
Anales del Jardín Botánico de Madrid , 1999,
Abstract: Problems of different kinds, with species of the genus Adenocarpus -group complicatus and gr. hispanicus- are analysed. A. anisochilus Boiss, is accepted at the specific leve!. Within A. complicatus s.l. the problems of identity of A. parvifolius DC. an A. intermedius DC. are discussed. A. desertorum Castrov., sp. nov., is described. Within the group hispanicus, the type material of A. hispanicus (Lm.) DC. is studied to demónstrate that the ame should continué to be used in the traditional sense; the specific level for A. argyrophyllus (Rivas Goday) Caball. is proposed; A. hispanicus subsp. gredensis Rivas Mart. & Belmonte is considered as an hybrid between A. hispanicus and A. argyrophyllus, while A. hispanicus subsp. neilensis Rivas Mart. & G. Navarro is interpreted as a form without any important taxonomic valué of A. hispanicus Se analizan problemas de diversa índole de algunas especies de Adenocarpus de los grupos complicatus e hispanicus y se acepta A. anisochilus Boiss, con el rango de especie. Dentro del grupo A. complicatus se analizan los problemas de identidad de A. parvifolius DC. y A. intermedius DC. y se describe A. desertorum Castrov., sp. nov. Dentro del grupo hispanicus se analiza el material tipo para demostrar que el nombre se debe seguir aplicando en sentido tradicional; se propone tratar A. argyrophyllus (Rivas Goday) Caball. en el rango específico; se considera que A. hispanicus subsp. gredensis Rivas Mart. & Belmonte podría ser una de las formas híbridas entre A. hispanicus y A. argyrophyllus, mientras que A. hispanicus subsp. neilensis Rivas Mart. & G. Navarro es interpretada como una forma más de A. hispanicus.

Variaciones en la aplicación de técnicas médicas en atención primaria
Sobrequés,J.; Bolíbar,B.; Unzueta,L.; Prados,J.D.; Leiva,F.; Boerma,W.;
Gaceta Sanitaria , 2002, DOI: 10.1590/S0213-91112002000600007
Abstract: objectives: to describe the application of medical techniques (atm) in spain and to analyze the relationship with diverse characteristics related to general practitioners and the center of primary health. design: multicenter cross-sectional study. setting: three hundred nineteen general practitioners working in primary care centers in the restructured public sector of the autonomous communities of andalusia, basque country and catalonia in spain. main measurements: structured and validated questionnaire comprising 100 items in four sections: general characteristics of the physician and health center, task profile, and job satisfaction. the questionnaire was sent by mail to the health center (andalusia and basque country) or to the home (catalonia). for the analysis an index variable was created from the answers to the questions on amt. results: the index variable of amt obtained a mean value of 10.02 (sd = 4.55). andalusia obtained the highest value (median: 11.11; sd: 4.33) of the three autonomous communities in the study (p = .012). amt acquired significantly higher values when associated with: masculine sex (sample from the three autonomous communities; p = .046), rural environment, teamwork, availability of basic equipment, fewer patients, and reduced work load. conclusions: index of atm in spain is significantly different in the three spanish communities under study. the quality of the sanitary services evaluated from the dimension of the atm seems to be much related with demographic characteristics, the readiness in the consultations of scientific-technical stuff and the appropriate time for medical consultations.

Gaceta Sanitaria , 2002,
Abstract: Objetivo: Describir la aplicación de técnicas médicas (ATM) en tres comunidades autónomas espa olas (Andalucía, Catalu a y País Vasco) y analizar sus relaciones con diversas características relacionadas con los médicos de atención primaria y el centro de salud. Dise o: Estudio multicéntrico, transversal. Emplazamiento: Un total de 319 médicos generales que trabajaban en los centros de atención primaria del sector público reformado en las comunidades de Andalucía, País Vasco y Catalu a. Mediciones principales: Cuestionario estructurado y validado de 100 preguntas en cuatro apartados: características generales del profesional y centro de trabajo, perfil de actividad y satisfacción laboral. éste fue enviado por correo al centro de trabajo (Andalucía y Euskadi) o domicilio particular (Catalu a). Para el análisis se creó una variable índice a partir de las respuestas de las preguntas de ATM. Resultados: La variable índice de ATM obtuvo un valor medio (desviación estándar [DE]) de 10,02 (4,55) y Andalucía el valor más alto (media [DE]: 11,11 [4,33]) de las tres comunidades del estudio (p = 0,012). La variable índice ATM adquiere valores significativamente más altos en relación con: el sexo masculino (muestra de tres comunidades autónomas; p = 0,046), el ámbito rural, el trabajo en equipo, la disponibilidad de equipamiento básico, el número de pacientes más reducido y menor carga asistencial. Conclusiones: Los índices de ATM en Espa a son significativamente distintos en las tres comunidades espa olas estudiadas. La calidad de la asistencia sanitaria evaluada desde la dimensión de la ATM parece estar muy relacionada con características demográficas, la disponibilidad en las consultas del material científico-técnico y el tiempo adecuado de las visitas médicas.
Ontology of a scene based on Java 3D architecture.
Holman Bolívar Barón,Rubén González Crespo,Oscar Sanjuán Martínez
International Journal of Interactive Multimedia and Artificial Intelligence , 2009,
Abstract: The present article seeks to make an approach to the class hierarchy of a scene built with the architecture Java 3D, to develop an ontology of a scene as from the semantic essential components for the semantic structuring of the Web3D. Java was selected because the language recommended by the W3C Consortium for the Development of the Web3D oriented applications as from X3D standard is Xj3D which compositionof their Schemas is based the architecture of Java3D In first instance identifies the domain and scope of the ontology, defining classes and subclasses that comprise from Java3D architecture and the essential elements of a scene, as its point of origin, the field of rotation, translation The limitation of the scene and the definition of shaders, then define the slots that are declared in RDF as a framework for describing the properties of the classes established from identifying thedomain and range of each class, then develops composition of the OWL ontology on SWOOP Finally, be perform instantiations of the ontology building for a Iconosphere object as from class expressions defined.

Abstract: Objectives: to evaluate the effectiveness of a fast track diagnosis and treatment program for colorectal cancer (CRC) in reducing the diagnosis to treatment interval (DTI) and tumor stage. To analyze the association between DTI and tumor stage. Methods: a quasi-experimental study with a control group was conducted, and 156 incident cases of CRC referred through a preferential pathway between July 2005 and December 2008 in a tertiary hospital were included, after excluding those treated urgently, treated by endoscopic polypectomy only or having periodic colonoscopies. A control group of 156 patients was randomly selected from all the patients referred through habitual pathways, frequency matched by tumor location, age and year of entry. Data was analyzed with multivariate linear and logistic regression. Results: mean DTI was 39.20 days (95% CI: 36.21-42.42) for fast track patients and 63.40 days (95% CI: 57.08-70.41) for controls (p < 0.001), and this difference persisted after multivariate analysis. The odds of having a DTI longer than 30 days was 4.79 (95% CI: 2.19-10.51) higher for controls. There were no significant differences in tumor stage according to the pathway followed. Independently of the track followed, a DTI longer than 30 days was associated with advanced tumor stages for colon cancer, while it was associated with low stages for rectal cancer. Conclusions: the PDTR strategy is effective in reducing DTI and may reduce patients' and relatives' anxiety. However, it is far from reaching the DTI recommended. The achieved reduction of the delay has no impact on tumor stage. Objetivos: evaluar la efectividad de un programa de diagnóstico y tratamiento rápido (PDTR) del cáncer colorrectal (CCR) en la reducción del intervalo diagnóstico-terapéutico (IDT) y el estadio tumoral. Analizar la asociación entre IDT y estadio tumoral. Métodos: estudio cuasiexperimental con grupo control en el que se incluyeron 156 casos incidentes de CCR atendidos por el PDTR entre julio de 2005 y diciembre de 2008 en un hospital de tercer nivel, tras excluir los que requirieron tratamiento urgente, tratados solo por polipectomía endoscópica o con colonoscopías periódicas. Un grupo control de 156 pacientes fue seleccionado al azar de los atendidos por el circuito habitual con la misma localización tumoral, edad y a o de ingreso. Para el análisis se utilizó regresión lineal y logística. Resultados: la media del IDT fue de 39,20 días (IC 95%: 36,21-42,42) en los pacientes del programa y de 63,40 días (IC 95%: 57,08-70,41) en el grupo control (p < 0,001); esta diferencia se
