Les meules rotatives du site ibérique d'Alcorda Park (Calafell, Baix Penedès, Tarragona)

El jaciment ibèric d' Alorda Park està situat a la costa central de Catalunya, a uns 30 km al nordest de Tarragona. El jaciment, l'ocupació del qual es data principalment entre el s. VI i el III aC, ha estat excavat extensament des de 1983. Els treballs d'excavació han lliurat sis metae i disset catilli de molins rotatius, la major part dels quals han estat reutilitzats per a usos secundaris. D' altra banda, cap molí rotatiu ha estat trobat in situ a l'interior d'una casa, de manera que es dedueix que la molta amb aquests instruments era probablement una activitat practicada en instal·lacions communals o bé per especialistes. Pel que fa a la funcionalitat d'aquestes peces, les anàlisis de residus indiquen que eren utilitzades per a la molta de cereals i, en un sol cas, de faves. Pel que fa a la cronologia, el més antic d'aquests exemplars data de mitjan segle V aC, i la utilització dels molins de rotació continua fins a finals de l'ocupació de l'assentament. Al llarg d'aquests tres segles, els molins rotatius d' Alorda Park sofreixen una evolució morfològica els trets essencials de la qual han pogut ser establerts. Els exemplars presentats són morfologicament similars a altres molins iberics de la costa central de Catalunya, pero es diferencien considerablement dels models documentats al País Valencia, a Ullastret i a la Gal·lia meridional. Aquest fet sembla indicar l'existència de tradicions locals ben caracteritzades, que hauran de ser precisades per les recerques futures. Finalment, cal observar que, segons les analisis de residus, els altres instruments lítics o de triturat descoberts al jaciment (molins de vaivé, morters) han estat utilitzats per a la transformació de materies primeres.

La migració primaveral d'ocells als Aiguamolls de l'Empordà (Girona): primer anellament de Becadell Gros (Gallinago Media) a la Península Ibèrica

En aquest treball s'exposen els resultats obtinguts en la campanya 1994 d'anellament d'ocells inclosa dins del projecte italià Piccole Isole. Es demostra que el factor meteorològic afecta directament la fenologia migratòria de diferents espècies d'ocells. Es pretén també estudiar la influència dels diferents hàbitats en el nombre i en la diversitat de captures. Es recullen també en aquest treball les principals espècies visualitzades durant la campanya, com també l'elevat nombre de controls estrangers recuperats. Dintre de les captures i l'anellament posterior, destaca sobretot la d'un becadell gros (Gallinago media) fets per primera vegada a la peninsula Ibèrica

Cultural events and tourist development in Catalonia (Spain)

From the point of view of local development cultural tourism events represent an opportunity since they are distributed homogeneously by the Catalan territory and are experiencing a vertiginous growth as a way to differentiate the existing supply. In our study a sample of 264 telephone surveys made to organizers of events in Catalonia has been compiled, with the purpose of characterizing the existing supply, thematic typologies, management models, commercialization inputs and economic impact. The results allow us to characterize events from the point of view of their tourist potential. Finally some recommendations are set out to develop future tourism policies based on events according to product differentiation, seasonality, competitiveness and creativity.

Cultural events as tourism supply in coastal Catalan resorts

During the last three decades, the number of tourism events has been growing in Catalan coastal resorts because of the recover of Catalan cultural traditions, festivals and folklore, and also because of tourism growth. Catalan tourism resorts use events as catalysers for new supply and as a mean to differentiate and singularize themselves from their competitors. The tourism potential of cultural events is undeniable but there are some problems that prevent a more effective impact as economic and regional development agents. This paper reflects some discussions and conclusions obtained from the analysis of 264 valid responses of a survey made to different Catalan event organizers in 2008 and 2009. We describe and characterize cultural event supply in coastal resorts in order to study the events tourism importance, their capacity to generate and spread economic development, and their managerial model. The analysis is made in a geographical basis, comparing the results of the territorial organization of events of the city of Barcelona, coastal and inland municipalities. Finally some considerations about event regional tourism policy and tourism development are discussed.

Local and Regional Scale Determinants of Biodiversity Patterns in Boreal Agricultural Landscapes

This thesis examines the local and regional scale determinants of biodiversity patterns using existing species and environmental data. The research focuses on agricultural environments that have experienced rapid declines of biodiversity during past decades. Existing digital databases provide vast opportunities for habitat mapping, predictive mapping of species occurrences and richness and understanding the speciesenvironment relationships. The applicability of these databases depends on the required accuracy and quality of the data needed to answer the landscape ecological and biogeographical questions in hand. Patterns of biodiversity arise from confounded effects of different factors, such as climate, land cover and geographical location. Complementary statistical approaches that can show the relative effects of different factors are needed in biodiversity analyses in addition to classical multivariate models. Better understanding of the key factors underlying the variation in diversity requires the analyses of multiple taxonomic groups from different perspectives, such as richness, occurrence, threat status and population trends. The geographical coincidence of species richness of different taxonomic groups can be rather limited. This implies that multiple geographical regions should be taken into account in order to preserve various groups of species. Boreal agricultural biodiversity and in particular, distribution and richness of threatened species is strongly associated with various grasslands. Further, heterogeneous agricultural landscapes characterized by moderate field size, forest patches and non-crop agricultural habitats enhance the biodiversity of rural environments. From the landscape ecological perspective, the major threats to Finnish agricultural biodiversity are the decline of connected grassland habitat networks, and general homogenization of landscape structure resulting from both intensification and marginalization of agriculture. The maintenance of key habitats, such as meadows and pastures is an essential task in conservation of agricultural biodiversity. Furthermore, a larger landscape context should be incorporated in conservation planning and decision making processes in order to respond to the needs of different species and to maintain heterogeneous rural landscapes and viable agricultural diversity in the future.

The effects of regional educational policies on school failure in Spain

This paper presents a regional analysis of the effects of educational policies implemented in Spain between 1992 and 2003, focusing specifically on school failure rates. We consider the impact of expenditure per pupil, class size, and pupil-teacher ratio on dropout rates at the end of compulsory education and on the proportion of early school-leavers in the 18-24 year age group. Our results indicate that higher levels of educational expenditure per pupil and lower class sizes and pupil-teacher ratios reduce rates of dropout and early school-leaving (although class-size is not always significant). However, the magnitude of the effects of these variables is small at the average level.

Forecasting tourism demand to Catalonia: neural networks vs. time series models

The increasing interest aroused by more advanced forecasting techniques, together with the requirement for more accurate forecasts of tourismdemand at the destination level due to the constant growth of world tourism, has lead us to evaluate the forecasting performance of neural modelling relative to that of time seriesmethods at a regional level. Seasonality and volatility are important features of tourism data, which makes it a particularly favourable context in which to compare the forecasting performance of linear models to that of nonlinear alternative approaches. Pre-processed official statistical data of overnight stays and tourist arrivals fromall the different countries of origin to Catalonia from 2001 to 2009 is used in the study. When comparing the forecasting accuracy of the different techniques for different time horizons, autoregressive integrated moving average models outperform self-exciting threshold autoregressions and artificial neural network models, especially for shorter horizons. These results suggest that the there is a trade-off between the degree of pre-processing and the accuracy of the forecasts obtained with neural networks, which are more suitable in the presence of nonlinearity in the data. In spite of the significant differences between countries, which can be explained by different patterns of consumer behaviour,we also find that forecasts of tourist arrivals aremore accurate than forecasts of overnight stays.

Antipsychotic polypharmacy in a regional health service: a population-based study

Background To analyse the extent and profile of outpatient regular dispensation of antipsychotics, both in combination and monotherapy, in the Barcelona Health Region (Spain), focusing on the use of clozapine and long-acting injections (LAI). Methods Antipsychotic drugs dispensed for people older than 18 and processed by the Catalan Health Service during 2007 were retrospectively reviewed. First and second generation antipsychotic drugs (FGA and SGA) from the Anatomical Therapeutic Chemical classification (ATC) code N05A (except lithium) were included. A patient selection algorithm was designed to identify prescriptions regularly dispensed. Variables included were age, gender, antipsychotic type, route of administration and number of packages dispensed. Results A total of 117,811 patients were given any antipsychotic, of whom 71,004 regularly received such drugs. Among the latter, 9,855 (13.9%) corresponded to an antipsychotic combination, 47,386 (66.7%) to monotherapy and 13,763 (19.4%) to unspecified combinations. Of the patients given antipsychotics in association, 58% were men. Olanzapine (37.1%) and oral risperidone (36.4%) were the most common dispensations. Analysis of the patients dispensed two antipsychotics (57.8%) revealed 198 different combinations, the most frequent being the association of FGA and SGA (62.0%). Clozapine was dispensed to 2.3% of patients. Of those who were receiving antipsychotics in combination, 6.6% were given clozapine, being clozapine plus amisulpride the most frequent association (22.8%). A total of 3.800 patients (5.4%) were given LAI antipsychotics, and 2.662 of these (70.1%) were in combination. Risperidone was the most widely used LAI. Conclusions The scant evidence available regarding the efficacy of combining different antipsychotics contrasts with the high number and variety of combinations prescribed to outpatients, as well as with the limited use of clozapine.

Vessana a Vessana. Reflexions sobre la pràctica dels establiments emfitèutics a la regió de Girona (segles XVIII-XIX)

Tenim documentats més de 30.000 contractes d'establiment emfitèutic (la majoria, amb caràcter de subestabliment) concedits a la regió de Girona (actuals comarques del Baix i de l'Alt Empordà, del Gironès i de La Selva) entre 1768 i 1862, anys en què van ser inscrits en els llibres del Registre d’hipoteques. Sabem que durant aquests mateixos anys se'n concediren molts més, ja que ens manca la informació relativa a l'ofici de Figueres entre 1774 i 1806 i la comarca de l’Alt Empordà va concentrar un 40% dels establiments concedits entre 1806 i 1862. És molt possible, doncs, que el nombre total s'apropés als 35.000. La xifra no és negligible; a mitjan segle XIX vivien a la regió unes cinquanta mil famílies. Es fa necessari, doncs, reflexionar sobre aquesta pràctica

Problèmes dus aux fistules d'hémodialyse: un réseau régional de prise en charge [Problems related to haemodialysis vascular accesses: a regional network of care]

The number of patients treated by haemodialysis (HD) is continuously increasing. The complications associated with vascular accesses represent the first cause of hospitalisation in these patients. Since 2001 nephrologists, surgeons, angiologists and radiologists at the CHUV are working to develop a multidisciplinary model that includes planning and monitoring of HD accesses. In this setting the echo-Doppler represents an important tool of investigation. Every patient is discussed and decisions are taken during a weekly multidisciplinary meeting. A network has been created with nephrologists of peripheral centres and other specialists. This model allows to centralize investigational information and coordinate patient care while keeping and even developing some investigational activities and treatment in peripheral centres.

El Museo Regional del Rif (Marruecos). Proyecto científico y cultural sobre la constitución de un museo de sociedad del Rif.

The end of this paper is to offer a Planning Project aimed to the prospective museum of the Rif society. The authors, unaware of the actual purpose of both political and cultural institutions, which eventually will decide about the museum and its location, just want to attract the attention of those responsible for some aspects and the chronological periods that the Planning Project must take into account to assure the success of this new Riffian cultural institution.

De la guerra de l'Empordà (1128) a la mortaldat de 1131: gènesi, extensió i extinció d'una fam. Per a una història de les crisis alimentàries a la Catalunya medieval

In the history of food shortages and subsistence crises which affected the Catalan counties during the eleventh and twelfth centuries, the famine of 1129-1131 deserves special mention. Originating in the war of 1128 involving the Empordà and neighboring counties, this famine affected the city of Barcelona and other points of Catalonia (Winter, 1131) and created conditions for the spread of a deadly epidemic (July 1130 -January 1132).

Patterns of practice of regional nodal irradiation in breast cancer: results of the European Organization for Research and Treatment of Cancer (EORTC) NOdal Radiotherapy (NORA) survey.

BACKGROUND: Predicting outcome of breast cancer (BC) patients based on sentinel lymph node (SLN) status without axillary lymph node dissection (ALND) is an area of uncertainty. It influences the decision-making for regional nodal irradiation (RNI). The aim of the NORA (NOdal RAdiotherapy) survey was to examine the patterns of RNI. METHODS: A web-questionnaire, including several clinical scenarios, was distributed to 88 EORTC-affiliated centers. Responses were received between July 2013 and January 2014. RESULTS: A total of 84 responses were analyzed. While three-dimensional (3D) radiotherapy (RT) planning is carried out in 81 (96%) centers, nodal areas are delineated in only 51 (61%) centers. Only 14 (17%) centers routinely link internal mammary chain (IMC) and supraclavicular node (SCN) RT indications. In patients undergoing total mastectomy (TM) with ALND, SCN-RT is recommend by 5 (6%), 53 (63%) and 51 (61%) centers for patients with pN0(i+), pN(mi) and pN1, respectively. Extra-capsular extension (ECE) is the main factor influencing decision-making RNI after breast conserving surgery (BCS) and TM. After primary systemic therapy (PST), 49 (58%) centers take into account nodal fibrotic changes in ypN0 patients for RNI indications. In ypN0 patients with inner/central tumors, 23 (27%) centers indicate SCN-RT and IMC-RT. In ypN1 patients, SCN-RT is delivered by less than half of the centers in patients with ypN(i+) and ypN(mi). Twenty-one (25%) of the centers recommend ALN-RT in patients with ypN(mi) or 1-2N+ after ALND. Seventy-five (90%) centers state that age is not considered a limiting factor for RNI. CONCLUSION: The NORA survey is unique in evaluating the impact of SLNB/ALND status on adjuvant RNI decision-making and volumes after BCS/TM with or without PST. ALN-RT is often indicated in pN1 patients, particularly in the case of ECE. Besides the ongoing NSABP-B51/RTOG and ALLIANCE trials, NORA could help to design future specific RNI trials in the SLNB era without ALND in patients receiving or not PST.
