Why Italy and not Spain?: comparing two industrialization processes from a dissagregate time-series perspective

This study presents new evidence concerning the uneven processes of industrialization innineteenth century Spain and Italy based on a disaggregate analysis of the productivesectors from which the behaviour of the aggregate indices is comprised. The use of multivariate time-series analysis techniques can aid our understanding and characterization of these two processes of industrialization. The identification of those sectors with key rolesin leading industrial growth provides new evidence concerning the factors that governed thebehaviour of the aggregates in the two economies. In addition, the analysis of the existenceof interindustry linkages reveals the scale of the industrialization process, and wheresignificant differences exist, accounts for many of the divergences recorded in the historiography for the period 1850-1913.

Networks of people in specialty production: family firms in the iron and steel Wire industries in Spain (1870-2000)

Capital intensive industries in specialized niches of production have constituted solid ground for family firms in Spain , as evidenced by the experience of the iron and steel wire industries between 1870 and 2000. The embeddedness of these firms in their local and regional environments have allowed the creation of networks that, together with favourable institutional conditions, significantly explain the dominance of family entrepreneurship in iron and steel wire manufacturing in Spain, until the end of the 20 th century. Dominance of family firms at the regional level has not been not an obstacle for innovation in wire manufacturing in Spain, which has taken place even when institutional conditions blocked innovation and traditional networking. Therefore, economic theories about the difficulties dynastic family firms may have to perform appropriately in science-based industries must be questioned

Strange nonchaotic attractors in Harper maps

We study the existence of strange nonchaotic attractors (SNA) in the family of Harper maps. We prove that for a set of parameters of positive measure, the map possesses a SNA. However, the set is nowhere dense. By changing the parameter arbitrarily small amounts, the attractor is a smooth curve and not a SNA.

Periodic points of holomorphic maps via Lefschetz numbers

In this paper we study the set of periods of holomorphic maps on compact manifolds, using the periodic Lefschetz numbers introduced by Dold and Llibre, which can be computed from the homology class of the map. We show that these numbers contain information about the existence of periodic points of a given period; and, if we assume the map to be transversal, then they give us the exact number of such periodic orbits. We apply this result to the complex projective space of dimension n and to some special type of Hopf surfaces, partially characterizing their set of periods. In the first case we also show that any holomorphic map of CP(n) of degree greater than one has infinitely many distinct periodic orbits, hence generalizing a theorem of Fornaess and Sibony. We then characterize the set of periods of a holomorphic map on the Riemann sphere, hence giving an alternative proof of Baker's theorem.

Chagas Disease among the Latin American Adult population attending in a primary care center in Barcelona, Spain

Background/Aims: The epidemiology of Chagas disease, until recently confined to areas of continental Latin America, has undergone considerable changes in recent decades due to migration to other parts of the world, including Spain. We studied the prevalence of Chagas disease in Latin American patients treated at a health center in Barcelona and evaluated its clinical phase. We make some recommendations for screening for the disease. Methodology/Principal Findings: We performed an observational, cross-sectional prevalence study by means of an immunochromatographic test screening of all continental Latin American patients over the age of 14 years visiting the health centre from October 2007 to October 2009. The diagnosis was confirmed by serological methods: conventional in-house ELISA (cELISA), a commercial kit (rELISA) and ELISA using T cruzi lysate (Ortho-Clinical Diagnostics) (oELISA). Of 766 patients studied, 22 were diagnosed with T. cruzi infection, showing a prevalence of 2.87% (95% CI, 1.6-4.12%). Of the infected patients, 45.45% men and 54.55% women, 21 were from Bolivia, showing a prevalence in the Bolivian subgroup (n = 127) of 16.53% (95% CI, 9.6-23.39%). All the infected patients were in a chronic phase of Chagas disease: 81% with the indeterminate form, 9.5% with the cardiac form and 9.5% with the cardiodigestive form. All patients infected with T. cruzi had heard of Chagas disease in their country of origin, 82% knew someone affected, and 77% had a significant history of living in adobe houses in rural areas. Conclusions: We found a high prevalence of T. cruzi infection in immigrants from Bolivia. Detection of T. cruzi¿infected persons by screening programs in non-endemic countries would control non-vectorial transmission and would benefit the persons affected, public health and national health systems.

Géopatrimoines des trois Chablais. Identification et valorisation des témoins glaciaires

Cette recherche s'applique aux témoins glaciaires des Chablais dans quatre de leurs dimensions : géopatrimoine, connaissance objective, inventaire de géosites et valorisation. Elle est organisée sur le canevas d'un processus de patrimonialisation auquel elle participe et qu'elle interroge à la fois. En 2009, débutait le projet 123 Chablais, pour une durée de quatre ans. Il concernait l'ensemble du territoire chablaisien, réparti sur deux pays (France et Suisse) et trois entités administratives (département de la Haute-Savoie, cantons de Vaud et du Valais). Ce projet, élaboré dans le cadre du programme Interreg IV France-Suisse, avait pour but de dynamiser le développement économique local en s'appuyant sur les patrimoines régionaux. Le géopatrimoine, identifié comme une de ces ressources, faisait donc l'objet de plusieurs actions, dont cette recherche. En parallèle, le Chablais haut-savoyard préparait sa candidature pour rejoindre l'European Geopark Network (EGN). Son intégration, effective dès 2012, a fait de ce territoire le cinquième géoparc français du réseau. Le Geopark du Chablais fonde son identité géologique sur l'eau et la glace, deux thématiques intimement liées aux témoins glaciaires. Dans ce contexte d'intérêt pour le géopatrimoine local et en particulier pour le patrimoine glaciaire, plusieurs missions ont été assignées à cette recherche qui devait à la fois améliorer la connaissance objective des témoins glaciaires, inventorier les géosites glaciaires et valoriser le patrimoine glaciaire. Le premier objectif de ce travail était d'acquérir une vision synthétique des témoins glaciaires. Il a nécessité une étape de synthèse bibliographique ainsi que sa spatialisation, afin d'identifier les lacunes de connaissance et la façon dont ce travail pouvait contribuer à les combler. Sur cette base, plusieurs méthodes ont été mises en oeuvre : cartographie géomorphologique, reconstitution des lignes d'équilibre glaciaires et datations de blocs erratiques à l'aide des isotopes cosmogéniques produits in situ. Les cartes géomorphologiques ont été élaborées en particulier dans les cirques et vallons glaciaires. Les datations cosmogéniques ont été concentrées sur deux stades du glacier du Rhône : le Last Local Glacial Maximum (LLGM) et le stade de Monthey. Au terme de cette étape, les spécificités du patrimoine glaciaire régional se sont révélées être 1) une grande diversité de formes et des liens étroits avec différents autres processus géomorphologiques ; 2) une appartenance des témoins glaciaires à dix grandes étapes de la déglaciation du bassin lémanique. Le second objectif était centré sur le processus d'inventaire des géosites glaciaires. Nous avons mis l'accent sur la sélection du géopatrimoine en développant une approche basée sur deux axes (temps et espace) identifiés dans le volet précédent et avons ainsi réalisé un inventaire à thèmes, composé de 32 géosites. La structure de l'inventaire a également été explorée de façon à intégrer des critères d'usage de ces géosites. Cette démarche, soutenue par une réflexion sur les valeurs attribuées au géopatrimoine et sur la façon d'évaluer ces valeurs, nous a permis de mettre en évidence le point de vue anthropo - et scientifico - centré qui prévaut nettement dans la recherche européenne sur le géopatrimoine. L'analyse des résultats de l'inventaire a fait apparaître quelques caractéristiques du patrimoine glaciaire chablaisien, discret, diversifié, et comportant deux spécificités exploitables dans le cadre d'une médiation scientifique : son statut de « berceau de la théorie glaciaire » et ses liens étroits avec des activités de la vie quotidienne, en tant que matière première, support de loisir ou facteur de risque. Cette recherche a débouché sur l'élaboration d'une exposition itinérante sur le patrimoine glaciaire des Chablais. Ce produit de valorisation géotouristique a été conçu pour sensibiliser la population locale à l'impact des glaciers sur son territoire. Il présente une série de sept cartes de stades glaciaires, encadrées par les deux mêmes thématiques, l'histoire de la connaissance glaciaire d'une part, les témoins glaciaires et la société, d'autre part. -- This research focuses on glacial witnesses in the Chablais area according to four dimensions : geoheritage, objective knowledge, inventory and promotion of geosites. It is organized on the model of an heritage's process which it participates and that it questions both. In 2009, the project 123 Chablais started for a period of four years. It covered the entire chablaisien territory spread over two countries and three administrative entities (département of Haute-Savoie, canton of Vaud, canton of Valais). This project, developed in the framework of the Interreg IV France-Switzerland program, aimed to boost the local development through regional heritage. The geoheritage identified as one of these resources, was therefore the subject of several actions, including this research. In parallel, the French Chablais was preparing its application to join the European Geopark Network (EGN). Its integration, effective since 2012, made of this area the fifth French Geopark of the network. The Chablais Geopark geological identity was based on water and ice, two themes closely linked to the glacial witnesses. In this context of interest for the regional geoheritage and especially for the glacial heritage, several missions have been assigned to this research which should improve objective knowledge of glacial witnesses, inventory and assess glacial geosites. The objective knowledge's component was to acquire a synthetic vision of the glacial witnesses. It required a first bibliography synthesis step in order to identify gaps in knowledge and how this work could help to fill them. On this basis, several methods have been implemented: geomorphological mapping, reconstruction of the equilibrium-line altitude and dating of glacial erratic blocks using cosmogenic isotopes produced in situ. Geomorphological maps have been developed especially in glacial cirques and valleys. Cosmogenic datings were concentrated on two stages of the Rhone glacier: the Last Local Glacial Maximum (LLGM) and « the stage of Monthey ». After this step, the specificities of the regional glacial heritage have emerged to us as 1) a wide variety of forms and links to various other geomorphological processes; 2) belonging of glacial witnesses to ten major glacial stages of Léman Lake's deglaciation. In the inventory of glacial geosites component we focused on the selection of geoheritage. We developed an approach based on two axes (time and space) identified in the preceding components. We obtained a thematic inventory, consisting of 32 geosites. The structure of the inventory was also explored in the aim to integrate use criteria of geosites. This approach, supported by a thought on the values attributed to the geoheritage and how to assess these values allowed us to highlight the point of view much anthropological - and scientific -centered prevailing in the European research on geoheritage. The analysis of the inventory's results revealed some characteristics of chablaisien glacial heritage, discrete, diverse, and with two features exploitable in the context of a scientific mediation: its status as « cradle of the glacial theory » and its close links with activities of daily life, as raw material, leisure support and risk factor. This research leads to the development of a traveling exhibition on the glacial heritage of the Chablais area. It presents a series of seven glacial stage's cards, framed by the two themes mentioned above: « history of glacial knowledge » and « glacial witnesses and society ».

Improved segmentation of deep brain grey matter structures using magnetization transfer (MT) parameter maps.

Basal ganglia and brain stem nuclei are involved in the pathophysiology of various neurological and neuropsychiatric disorders. Currently available structural T1-weighted (T1w) magnetic resonance images do not provide sufficient contrast for reliable automated segmentation of various subcortical grey matter structures. We use a novel, semi-quantitative magnetization transfer (MT) imaging protocol that overcomes limitations in T1w images, which are mainly due to their sensitivity to the high iron content in subcortical grey matter. We demonstrate improved automated segmentation of putamen, pallidum, pulvinar and substantia nigra using MT images. A comparison with segmentation of high-quality T1w images was performed in 49 healthy subjects. Our results show that MT maps are highly suitable for automated segmentation, and so for multi-subject morphometric studies with a focus on subcortical structures.

Factors influencing privatization of urban solid waste collection: some evidence from Spain

In this paper we analyse some of the organisational aspects of the urban solid waste collection and, in particular, the privatization modality of contracting out. We start by discussing some of the theoretical aspects of contracting out. We then specify and estimate an explanatory model on a sample of municipalities that we surveyed. Our purpose is twofold: on the one hand, we identify the economic factors at work when deciding to contract out the service and, on the other hand, we analyse the role of ideological factors in choosing between the public production of the service or contracting it out. The results show a significant effect of the demand for waste collection on contracting out. There also appears to be a neighbouring effect as the municipalities close to other cities that contract out are also more prone to do so. Finally, the decisions to contract seem to have been motivated by pragmatic rather than ideological reasons.

Geographical determinants of the creation of manufacturing firms: The regions of Spain

La complexitat dels mecanismes que determinen l'entrada i la sortida de signatures augmenta quan diferències geogràfiques de l'estructura de producció, la capital humana i l'atur són considerades. Variacions interregionals en la tarifa de les noves de signatures dintre de cada activitat industrial persisteixen durant els períodes llargs de temps, una circumstància que indica que hi ha determinants no-conjunturals en la capacitat de regions per a crear nous projectes industrials. Aquest estudi està preocupat amb l'establiment d'influència variables geogràfiques sobre la fundació de nous establiments de la fabricació. Les indústries (NEIX la R 25) en les regions espanyoles (el BOIG 2) han estat preses com les unitats d'anàlisis per al període 1980-1992

Monitoring mortality as an indicator of influenza in Catalonia, Spain.

This study aimed to investigate the behaviour of two indicators of influenza activity in the area of Barcelona and to evaluate the usefulness of modelling them to improve the detection of influenza epidemics. DESIGN: Descriptive time series study using the number of deaths due to all causes registered by funeral services and reported cases of influenza-like illness. The study concentrated on five influenza seasons, from week 45 of 1988 to week 44 of 1993. The weekly number of deaths and cases of influenza-like illness registered were processed using identification of a time series ARIMA model. SETTING: Six large towns in the Barcelona province which have more than 60,000 inhabitants and funeral services in all of them. MAIN RESULTS: For mortality, the proposed model was an autoregressive one of order 2 (ARIMA (2,0,0)) and for morbidity it was one of order 3 (ARIMA (3,0,0)). Finally, the two time series were analysed together to facilitate the detection of possible implications between them. The joint study of the two series shows that the mortality series can be modelled separately from the reported morbidity series, but the morbidity series is influenced as much by the number of previous cases of influenza reported as by the previous mortality registered. CONCLUSIONS: The model based on general mortality is useful for detecting epidemic activity of influenza. However, because there is not an absolute gold standard that allows definition of the beginning of the epidemic, the final decision of when it is considered an epidemic and control measures recommended should be taken after evaluating all the indicators included in the influenza surveillance programme.

Dramatic decline of serogrup C meningococcal disease incidence in Catalonia (Spain) 24 months after a mass vaccination programme of children and young people

STUDY OBJECTIVES The objective of this study was to evaluate the effectiveness of a mass vaccination programme carried out in Catalonia (Spain) in the last quarter of 1997 in response to an upsurge of serogroup C meningococcal disease (SCMD). DESIGN Vaccination coverage in the 18 month to 19 years age group was investigated by means of a specific vaccination register. Vaccination effectiveness was calculated using the prospective cohort method. Cases of SCMD were identified on the basis of compulsory reporting and microbiological notification by hospital laboratories. Vaccination histories were investigated in all cases. Unadjusted and age adjusted vaccination effectiveness referred to the time of vaccination and the corresponding 95% confidence intervals (CI) were estimated at 6, 12, 18 and 24 months of follow up. SETTING All population aged 18 months to 19 years of Catalonia. MAIN RESULTS A total of seven cases of SCMD were detected at six months of follow up (one in the vaccinated cohort), 12 cases at 12 months (one in the vaccinated cohort), 19 cases at 18 months (two in the vaccinated cohort) and 24 at 24 months (two in the vaccinated cohort). The age adjusted effectiveness was 84% (95%CI 30, 97) at six months, 92% (95%CI 63, 98) at 12 months, 92% (95% CI 71, 98) at 18 months and 94% (95%CI 78, 98) at 24 months. In the target population, cases have been reduced by more than two thirds (68%) two years after the vaccination programme. In the total population the reduction was 43%. CONCLUSION Vaccination effectiveness has been high in Catalonia, with a dramatic reduction in disease incidence in the vaccinated cohort accompanied by a relevant reduction in the overall population. Given that vaccination coverage was only 54.6%, it may be supposed that this vaccination effectiveness is attributable, in part, to the herd immunity conferred by the vaccine.

Epidemiology of foodborne Norovirus outbreaks in Catalonia, Spain

Background: Noroviruses are one of the principal biological agents associated with the consumption of contaminated food. The objective of this study was to analyse the size and epidemiological characteristics of foodborne outbreaks of gastroenteritis in Catalonia, a region in the northeast of Spain.Methods: In all reported outbreaks of gastroenteritis associated with food consumption, faecal samples of persons affected were analysed for bacteria and viruses and selectively for parasites. Study variables included the setting, the number of people exposed, age, sex, clinical signs and hospital admissions. The study was carried out from October 2004 to October 2005.Results: Of the 181 outbreaks reported during the study period, 72 were caused by Salmonella and 30 by norovirus (NoV); the incidence rates were 14.5 and 9.9 per 100,000 person-years, respectively. In 50% of the NoV outbreaks and 27% of the bacterial outbreaks (p = 0.03) the number of persons affected was ¿10; 66.7% of NoV outbreaks occurred in restaurants; no differences in the attack rates were observed according to the etiology. Hospitalizations were more common (p = 0.03) in bacterial outbreaks (8.6%) than in NoV outbreaks (0.15%). Secondary cases accounted for 4% of cases in NoV outbreaks compared with 0.3% of cases in bacterial outbreaks (p < 0.001)Conclusion: Norovirus outbreaks were larger but less frequent than bacterial outbreaks, suggesting that underreporting is greater for NoV outbreaks. Food handlers should receive training on the transmission of infections in diverse situations. Very strict control measures on handwashing and environmental disinfection should be adopted in closed or partially-closed institutions.

Weakening processes in thrust faults: insights from the Monte Perdido thrust fault (southern Pyrenees, Spain)

The Monte Perdido thrust fault (southern Pyrenees) consists of a 6-m-thick interval of intensely deformed clay-bearing rocks. The fault zone is affected by a pervasive pressure solution seam and numerous shear surfaces. Calcite extensional-shear veins are present along the shear surfaces. The angular relationships between the two structures indicate that shear surfaces developed at a high angle (70°) to the local principal maximum stress axis r1. Two main stages of deformation are present. The first stage corresponds to the development of calcite shear veins by a combination of shear surface reactivation and extensional mode I rupture. The second stage of deformation corresponds to chlorite precipitation along the previously reactivated shear surfaces. The pore fluid factor k computed for the two deformation episodes indicates high fluid pressures during the Monte Perdido thrust activity. During the first stage of deformation, the reactivation of the shear surface was facilitated by a suprahydrostatic fluid pressure with a pore fluid factor kv equal to 0.89. For the second stage, the fluid pressure remained still high (with a k value ranging between 0.77 and 0.84) even with the presence of weak chlorite along the shear surfaces. Furthermore, evidence of hydrostatic fluid pressure during calcite cement precipitation supports that incremental shear surface reactivations are correlated with cyclic fluid pressure fluctuations consis- tent with a fault-valve model.
