Missatges autoreferencials dels actors del ritual de l'Id-al-ad·ha

L'article analitza la celebració de l'Id-al-ad·ha o "festa del sacrifici", ritual protagonitzat per la comunitat de musulmans el desè dia del mes de dhu-al-hijja. Es parteix d'exemples etnogràfics procedents del context de la diàspora musulmana al Tarragonès i de la societat emiral mauritana. El fenomen s'analitza des dels rols que els actors exerceixen en el ritual. L'argumentació vol subratllar la idea que tot ritual s'inscriu en un context social específic del qual n'és producte alhora que modulador, per mitjà del que Roy Rappaport anomena "missatges autoreferencials". Això no exclou l'existència d'un conjunt de denominadors comuns o "missatges canònics" entre les diverses pràctiques rituals referides.

A flood geodatabase and its climatological applications: the case of Catalonia for the last century

Floods are the natural hazards that produce the highest number of casualties and material damage in the Western Mediterranean. An improvement in flood risk assessment and study of a possible increase in flooding occurrence are therefore needed. To carry out these tasks it is important to have at our disposal extensive knowledge on historical floods and to find an efficient way to manage this geographical data. In this paper we present a complete flood database spanning the 20th century for the whole of Catalonia (NE Spain), which includes documentary information (affected areas and damage) and instrumental information (meteorological and hydrological records). This geodatabase, named Inungama, has been implemented on a GIS (Geographical Information System) in order to display all the information within a given geographical scenario, as well as to carry out an analysis thereof using queries, overlays and calculus. Following a description of the type and amount of information stored in the database and the structure of the information system, the first applications of Inungama are presented. The geographical distribution of floods shows the localities which are more likely to be flooded, confirming that the most affected municipalities are the most densely populated ones in coastal areas. Regarding the existence of an increase in flooding occurrence, a temporal analysis has been carried out, showing a steady increase over the last 30 years.

Tornadoes and waterspouts in Catalonia (1950-2009)

This paper presents a preliminary climatology of tornadoes and waterspouts in Catalonia (NE Iberian Peninsula). A database spanning 60 yr (1950-2009) has been developed on the basis of information collected from various sources such as weather reports, insurance companies, newspapers and damage surveys. This database has been subjected to a rigorous validation process, and the climatology describes its main features: timing, spatial pattern, and trends in the tornado and waterspout distribution. Results show the highest concentration of tornadoes from August to October, the highest density in the heavily populated coastal areas and a growing positive trend that is likely more closely linked to an increase in observation and perception rather than a real climatic trend.

Predictive ability of severe rainfall events over Catalonia for the year 2008

This paper analyses the predictive ability of quantitative precipitation forecasts (QPF) and the so-called "poor-man" rainfall probabilistic forecasts (RPF). With this aim, the full set of warnings issued by the Meteorological Service of Catalonia (SMC) for potentially-dangerous events due to severe precipitation has been analysed for the year 2008. For each of the 37 warnings, the QPFs obtained from the limited-area model MM5 have been verified against hourly precipitation data provided by the rain gauge network covering Catalonia (NE of Spain), managed by SMC. For a group of five selected case studies, a QPF comparison has been undertaken between the MM5 and COSMO-I7 limited-area models. Although MM5's predictive ability has been examined for these five cases by making use of satellite data, this paper only shows in detail the heavy precipitation event on the 9¿10 May 2008. Finally, the "poor-man" rainfall probabilistic forecasts (RPF) issued by SMC at regional scale have also been tested against hourly precipitation observations. Verification results show that for long events (>24 h) MM5 tends to overestimate total precipitation, whereas for short events (¿24 h) the model tends instead to underestimate precipitation. The analysis of the five case studies concludes that most of MM5's QPF errors are mainly triggered by very poor representation of some of its cloud microphysical species, particularly the cloud liquid water and, to a lesser degree, the water vapor. The models' performance comparison demonstrates that MM5 and COSMO-I7 are on the same level of QPF skill, at least for the intense-rainfall events dealt with in the five case studies, whilst the warnings based on RPF issued by SMC have proven fairly correct when tested against hourly observed precipitation for 6-h intervals and at a small region scale. Throughout this study, we have only dealt with (SMC-issued) warning episodes in order to analyse deterministic (MM5 and COSMO-I7) and probabilistic (SMC) rainfall forecasts; therefore we have not taken into account those episodes that might (or might not) have been missed by the official SMC warnings. Therefore, whenever we talk about "misses", it is always in relation to the deterministic LAMs' QPFs.

Trends in indices of daily precipitation extremes in Catalonia (NE Spain), 1951-2003

The aim of this paper is to quantitatively characterize the climatology of daily precipitation indices in Catalonia (northeastern Iberian Peninsula) from 1951 to 2003. This work has been performed analyzing a subset of the ETCCDI (Expert Team on Climate Change Detection and Indices) precipitation indices calculated from a new interpolated dataset of daily precipitation, namely SPAIN02, regular at 0.2° horizontal resolution (around 20 km) and from two high-quality stations: the Ebro and Fabra observatories. Using a jack-knife technique, we have found that the sampling error of the SPAIN02 regional averaged is relatively low. The trend analysis has been implemented using a Circular Block Bootstrap procedure applicable to non-normal distributions and autocorrelated series. A running trend analysis has been applied to analyze the trend persistence. No general trends at a regional scale are observed, considering the annual or the seasonal regional averaged series of all the indices for all the time windows considered. Only the consecutive dry days index (CDD) at annual scale shows a locally coherent spatial trend pattern; around 30% of the Catalonia area has experienced an increase of around 2¿3 days decade¿1. The Ebro and Fabra observatories show a similar CDD trend, mainly due to the summer contribution. Besides this, a significant decrease in total precipitation (around ¿10 mm decade¿1) and in the index "highest precipitation amount in five-day period" (RX5DAY, around ¿5 mm decade¿1), have been found in summer for the Ebro observatory.

Improving QPF by blending techniques at the Meteorological Service of Catalonia

The current operational very short-term and short-term quantitative precipitation forecast (QPF) at the Meteorological Service of Catalonia (SMC) is made by three different methodologies: Advection of the radar reflectivity field (ADV), Identification, tracking and forecasting of convective structures (CST) and numerical weather prediction (NWP) models using observational data assimilation (radar, satellite, etc.). These precipitation forecasts have different characteristics, lead time and spatial resolutions. The objective of this study is to combine these methods in order to obtain a single and optimized QPF at each lead time. This combination (blending) of the radar forecast (ADV and CST) and precipitation forecast from NWP model is carried out by means of different methodologies according to the prediction horizon. Firstly, in order to take advantage of the rainfall location and intensity from radar observations, a phase correction technique is applied to the NWP output to derive an additional corrected forecast (MCO). To select the best precipitation estimation in the first and second hour (t+1 h and t+2 h), the information from radar advection (ADV) and the corrected outputs from the model (MCO) are mixed by using different weights, which vary dynamically, according to indexes that quantify the quality of these predictions. This procedure has the ability to integrate the skill of rainfall location and patterns that are given by the advection of radar reflectivity field with the capacity of generating new precipitation areas from the NWP models. From the third hour (t+3 h), as radar-based forecasting has generally low skills, only the quantitative precipitation forecast from model is used. This blending of different sources of prediction is verified for different types of episodes (convective, moderately convective and stratiform) to obtain a robust methodology for implementing it in an operational and dynamic way.

Informe sobre el Seminari «Sistemes d'Informació per a l'Acció Cultural Local» (Barcelona, 25-28 de novembre de 1998)

El passat mes de novembre, l'Àrea de Cultura de la Diputació de Barcelona va organitzar Interacció'98, unes jornades de convocatòria estatal sobre polítiques i gestió cultural. La convocatòria d'enguany ¿la quarta edició¿ tractà d'un centre d'interès específic: «Cultura i poder local». Dins el marc d'Interacció'98, es va organitzar el seminari de «Sistemes d'informació per a l'acció cultural local». Aquest seminari es va organitzar amb l'intent de conjugar la reflexió teòrica amb la presentació de pràctiques amb resultats positius procedents d'organitzacions públiques de diversa adscripció temàtica i sectorial de tot l'Estat espanyol. El comú denominador va ser la seva significació quant a les possibilitats i limitacions dels sistemes d'informació per a l'acció cultural a escala territorial.

Blocs a la biblioteca penitenciària: un taller de dinamització cultural

Es descriu el taller de promoció cultural que encoratja un grup d'interns a crear i publicar blocs, i que es va iniciar l'estiu de 2006 al Centre Penitenciari de Joves de Barcelona, com una col·laboració entre el punt Òmnia i la biblioteca del centre i la Facultat de Biblioteconomia i Documentació de la Universitat de Barcelona. Els objectius han estat promoure l¿educació dels reclusos i millorar-ne el nivell d'informació, animar-los a llegir i escriure més, despertar o potenciar les pròpies habilitats tecnològiques, i ampliar el contacte que tenen amb el món exterior. Es presenten les biblioteques de presó com un agent de suport al desenvolupament intel·lectual, social i cultural dels interns, que pot ajudar-los en el camí de la superació personal. Es fa una valoració crítica de la resposta dels reclusos; l'experiència es considera positiva. I es fa una reflexió doble: sobre el fet que Internet dins la presó és un dret exigible que pot afavorir la integració social i laboral dels interns, i sobre certes necessitats de la biblioteca de presó, entesa com un instrument que influeix en aquesta futura integració.

Avaluació de revistes i avaluació de la recerca en humanitats i ciències socials a Catalunya: aproximació a un problema

The evaluation of the quality and impact of journals as a starting point to systematise the quality of research is an indirect method commonly used for obtaining information for systematic and major evaluation efforts, such as those needed for public tenders to aid projects and research groups. Nevertheless, this method runs into an important obstacle: preparing rankings of journals in the humanities and social sciences is considerably more complex than for those on experimental, biomedical or technological sciences. Cultural, linguistic and territorial components of research in the humanities and social sciences radically question the international rankings. Within this context, the article presents the experience of a study-in-progress whose intention is to evaluate the rankings of journals in the humanities and social sciences published in 1997 by the Generalitat de Catalunya. Even thought an attempt was made to bring this type of titles closer to the Catalan community of researchers, the initiative has been frequently surrounded by controversy and criticism and, at the present, does not enjoy the needed recognition of the Catalan academic sector.

Biblioteques «culturalment incorrectes»: les biblioteques de Canovelles i Ulldecona

L'escasa presència d'alguns símbols de la cultura mediàtica i popular a les biblioteques públiques, titllats de «culturalment incorrectes», és el punt de partida per a reflexionar sobre els models de fons bibliotecari. Cada vegada és més difícil d'establir uns límits sobre allò que cal tenir a la biblioteca i allò que cal excloure'n, L'experiència concreta de dues biblioteques, Canovelles i Ulldecona, aporta arguments al debat teòric i el situa en el marc d'una política bibliotecària integradora de la diversitat cultural.
