In this paper we use a gravity model to study the trade performance of French and Spanishborder regions relatively to non-border regions, over the past two decades. We find that,controlling for their size, proximity and location characteristics, border regions trade onaverage between 62% and 193% more with their neighbouring country than other regions,and twice as much if they are endowed with good cross border transport infrastructures.Despite European integration, however, this trade outperformance has fallen for the mostperipheral regions within the EU. We show that this trend was linked in part to a shift in the propensity of foreign investors to move their affiliates from the regions near their home market to the regions bordering the EU core.

En aquest treball, s¿hi replanteja l¿estatut de Tortosa a partir de la fi del segle II, tot considerant de nou CIL II2 14, 787 i CIL II2 14, 788. La possibilitat que l¿emperador efímer Pèrtinax concedís a Dertosa el privilegi colonial, com ho féu amb altres ciutats, és analitzada per tal de justificar el text de l¿última inscripció.

This study examines whether math anxiety and negative attitudes toward mathematics have an effect on university students" academic achievement in a methodological course forming part of their degree. A total of 193 students were presented with a math anxiety test and some questions about their enjoyment, self-confidence and motivation regarding mathematics, and their responses were assessed in relation to the grades they had obtained during continuous assessment on a course entitled"Research Design". Results showed that low performance on the course was related to math anxiety and negative attitudes toward mathematics. We suggest that these factors may affect students" performance and should therefore be taken into account in attempts to improve students" learning processes in methodological courses of this kind.

El proyecto consiste principalmente en definir y desarrollar una herramienta de gestión de metadatos de negocio para los indicadores clave de rendimiento. Actualmente no existe ninguna herramienta BI que permita almacenar información de negocio más allá de las especificaciones técnicas. Dicha aplicación, actuará como repositorio centralizado de la definición de los indicadores clave de negocio de la compañia incluyendo información del metadato del indicador, (tal como, responsable del indicador, dimensiones de análisis, profundidad histórica, frecuencia de actualización, procesos de negocio implicados, etc.).

Resveratrol has been shown to have beneficial effects on diseases related to oxidant and/or inflammatory processes and extends the lifespan of simple organisms including rodents. The objective of the present study was to estimate the dietary intake of resveratrol and piceid (R&P) present in foods, and to identify the principal dietary sources of these compounds in the Spanish adult population. For this purpose, a food composition database (FCDB) of R&P in Spanish foods was compiled. The study included 40 685 subjects aged 3564 years from northern and southern regions of Spain who were included in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Spain cohort. Usual food intake was assessed by personal interviews using a computerised version of a validated diet history method. An FCDB with 160 items was compiled. The estimated median and mean of R&P intake were 100 and 933 mg/d respectively. Approximately, 32% of the population did not consume RΠ The most abundant of the four stilbenes studied was trans-piceid (53·6 %), followed by trans-resveratrol (20·9 %), cis-piceid (19·3 %) and cis-resveratrol (6·2 %). The most important source of R&P was wines (98·4 %) and grape and grape juices (1·6 %), whereas peanuts, pistachios and berries contributed to less than 0·01 %. For this reason the pattern of intake of R&P was similar to the wine pattern. This is the first time that R&P intake has been estimated in a Mediterranean country.

Background To determine the diagnostic and prognostic capability of urinary and tumoral syndecan-1 (SDC-1) levels in patients with cancer of the urinary bladder. Methods SDC-1 levels were quantitated by enzyme-linked immunosorbent assay (ELISA) in 308 subjects (102 cancer subjects and 206 non-cancer subjects) to assess its diagnostic capabilities in voided urine. The performance of SDC-1 was evaluated using the area under the curve of a receiver operating characteristic curve. In addition, immunohistochemical (IHC) staining assessed SDC-1 protein expression in 193 bladder specimens (185 cancer subjects and 8 non-cancer subjects). Outcomes were correlated to SDC-1 levels. Results Mean urinary levels of SDC-1 did not differ between the cancer subjects and the non-cancer subjects, however, the mean urinary levels of SDC-1 were reduced in high-grade compared to low-grade disease (p < 0.0001), and in muscle invasive bladder cancer (MIBC) compared to non-muscle invasive bladder cancer (NMIBC) (p = 0.005). Correspondingly, preliminary data note a shift from a membranous cellular localization of SDC-1 in normal tissue, low-grade tumors and NMIBC, to a distinctly cytoplasmic localization in high-grade tumors and MIBC was observed in tissue specimens. Conclusion Alone urinary SDC-1 may not be a diagnostic biomarker for bladder cancer, but its urinary levels and cellular localization were associated with the differentiation status of patients with bladder tumors. Further studies are warranted to define the potential role for SDC-1 in bladder cancer progression.

Las teorías sobre la invención histórica de la infancia y la adolescencia se han basado casi exclusivamente en fuentes occidentales (más exactamente centroeuropeas y anglosajonas), por lo que es urgente una reconceptualización en una óptica diacrónica y transcultural. Una de las conclusiones del encuentro «A criança e o jovem na America Latina», que tuvo lugar en Marilia (Brasil) en noviembre del 2001, organizado por la International Sociological Association, fue la necesidad de reconceptualizar la infancia y la juventud desde una perspectiva latinoamericana (como ámbito geográfico, académico y cultural). En este artículo proponemos retomar, en una perspectiva comparativa y como ejemplo de la riqueza y complejidad de las tareas pendientes, dos casos documentales y etnográficos recabados en nuestras propias indagaciones en México (Feixa, 1998b) y Chile (González, 2004a, 2004b), en la idea de comenzar a cursar esta «asignatura pendiente».

La relación entre historia, patrimonio y territorio, en unos espacios culturales de clara relevancia durante la Guerra Civil y la Segunda Guerra Mundial, permite reflexionar sobre algunas políticas públicas de memoria desarrolladas a raíz de la confluencia que se ha dado entre el Programa Memorial Democràtic impulsado por la Generalitat de Catalunya, la acción decidida de algunos ayuntamientos comprometidos en preservar la memoria histórica, el mundo académico representado por la Universidad y el asociacionismo civil.

Estudio sobre el papel desempeñado por las ciudades ibéricas de Iltirta y Auso en la primera organización territorial romana de Hispania, en especial durante el siglo II a. de C. Ambos fueron importantes centros de carácter regional; el análisis de los contextos grecoromanos, la numismática y los escasos restos arqueológicos conocidos así lo confirman. En realidad, el proceso fue la continuación de una realidad ya preexistente con anterioridad a la conquista romana.

Se describen una serie de ensayos de campo y laboratorio (pruebas de EAG, Electro-Anteno-Grama), para optimizar el tipo de trampa, la composición y la dosis de la mezcla atrayente, con miras a obtener un nivel máximo de capturas de machos de Sesamia nonagrioides y un mayor grado de selectividad. Igualmente se presentan las curvas de vuelo de la especie en zonas maiceras representativas de Cataluña y Aragón.

En el presente trabajo analizamos el proceso de elección de los diputados españoles en las Cortes Extraordinarias de Cádiz (1810-1813), la sociología de estos parlamentarios y su asistencia en el Parlamento. Después de efectuar el análisis observamos en primer lugar que hubo cuatro modalidades de elección de los diputados y que, una vez escogidos, nunca se cubrieron todos los puestos de diputado otorgados. En segundo lugar, detectamos que los diputados elegidos por los diversos entes que participaron en el proceso electoral fueron en su mayoría de condición social acomodada y representativos de la sociedad española, sobresaliendo en número el grupo de diputados eclesiásticos, de leyes y funcionarios.
