Catalonia was the only Mediterranean region among the early followers of the British Industrial Revolution in the second third of the nineteenth century. The roots of this industrialisation process can be traced back to the seventeenth and eighteenth centuries when the Catalan economy became successfully integrated in international trade and the region enjoyed an intensification of its agrarian and proto-industrial activities. These capitalist developments were subsequently reinforced by a successful printed calico manufacturing business concentrated in the city of Barcelona. Although the factory system was largely adopted by the cotton industry in the 1840s, the diffusion of the spinning jenny had occurred earlier in the 1790s. In this paper, in line with Allen (2009a, 2009b), we explore whether relative factor prices played a role in the widespread adoption of the spinning jenny in Catalonia.

The sloppy process of urbanization that took place in the outskirts of Barcelona from mid XIXth to mid XXth century resulted on large informal slums with evident urban deficiencies. The Metropolitan Masterplan of 1976 and its subsequent amendments could only partially improve the conditions of these areas of the city. Since 2005 some initiatives, in which local community or academic research played an important role, were undertaken following a tactical approach. The paper summarizes six proposed strategies that are a reaction to the traditional planning and zoning approach for the area. Some of them are currently been discussed or have already been included in the planning framework of the city.

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.

Background: Breast cancer (BC) causes more deaths than any other cancer among women in Catalonia. Early detection has contributed to the observed decline in BC mortality. However, there is debate on the optimal screening strategy. We performed an economic evaluation of 20 screening strategies taking into account the cost over time of screening and subsequent medical costs, including diagnostic confirmation, initial treatment, follow-up and advanced care. Methods: We used a probabilistic model to estimate the effect and costs over time of each scenario. The effect was measured as years of life (YL), quality-adjusted life years (QALY), and lives extended (LE). Costs of screening and treatment were obtained from the Early Detection Program and hospital databases of the IMAS-Hospital del Mar in Barcelona. The incremental cost-effectiveness ratio (ICER) was used to compare the relative costs and outcomes of different scenarios. Results: Strategies that start at ages 40 or 45 and end at 69 predominate when the effect is measured as YL or QALYs. Biennial strategies 50-69, 45-69 or annual 45-69, 40-69 and 40-74 were selected as cost-effective for both effect measures (YL or QALYs). The ICER increases considerably when moving from biennial to annual scenarios. Moving from no screening to biennial 50-69 years represented an ICER of 4,469€ per QALY. Conclusions: A reduced number of screening strategies have been selected for consideration by researchers, decision makers and policy planners. Mathematical models are useful to assess the impact and costs of BC screening in a specific geographical area.

The appearance of the Banco de Barcelona involved the formation of an investment compact network between its directors. In this work we studied how this investment network grew within a larger one, the one formed by the major investors in Catalonia during the period 1815-1866, as well as the role played by the top executives of the Bank inside it. Our findings indicate that some of the directors of the Bank held a central position in the main Catalan investors" network. This important role guaranteed reliable information on the progress of businesses. This information not only favored the operations of the institution, but also allowed its directors to take investment decisions inside the network. Moreover, the Bank interconnects individuals who were associated with different investors" sectors, which made the institution coalesced around an investing core with different important influences and connections.

To understand how tree growth has responded to recent climate warming, an understanding of the tree-climate-site complex is necessary. To achieve this, radial growth variability among 204 trees established before 1850 was studied in relation to both climatic and site factors. Seventeen forest stands were sampled in the Spanish Central Pyrenees. Three species were studied: Pinus uncinata, Abies alba, and Pinus sylvestris. For each tree, a ring-width residual chronology was built. All trees cross-dated well, indicating a common influence of the regional climate. For the 1952-1993 period, the radial growth of all species, especially P. uncinata, was positively correlated with warm Novembers during the year before ring formation and warm Mays of the year the annual ring formed. Differences in species-stand elevation modulated the growth-climate associations. Radial growth in P. uncinata at high elevation sites was reduced when May temperatures were colder and May precipitation more abundant. In the 20th century, two contrasting periods in radial growth were observed: one (1900-1949) with low frequency of narrow and wide rings, low mean annual sensitivity, and low common growth variation; and another (1950-1994) with the reverse characteristics. The increased variability in radial growth since the 1950s was observed for all species and sites, which suggests a climatic cause. The low shared variance among tree chronologies during the first half of the 20th century may result from a"relaxation" of the elevation gradient, allowing local site conditions to dominate macroclimatic influence. These temporal trends may be related to the recently reported increase of climatic variability and warmer conditions. This study emphasizes the need to carefully assess the relationships between radial growth and site conditions along ecological gradients to improve dendroclimatic reconstructions.

The herbarium BC-Trèmols was created during the second half of the 19th century by the Catalan chemist and botanist Frederic Trèmols Borrell. Between 1930 and 1960, the technician Antoni Marcos carried out a thorough review. The current collection consists of approximately 9000 specimen sheets; is made up of 58 volumes reordered by Marcos,two volumes with the original structure, four boxes of Hieracium and 85 boxes with additional material. Up to now 22 volumes and four boxes of Hieracium have been computerized (3695 specimens); we made an inventory at genus level of all volumes, and we computerized the original catalogue of the herbarium and the existing taxonomical fiches. We have also developed a preliminary inventory of the contents of the extra boxes. The analysis of these 3695 herbarium specimens clearly shows that it mainly consists of samples obtained by exchange (67.1%) especially within the Société Helvétique pour l"Échange des Plantes and the Societat Botànica Barcelonesa. Among the materials studied we found two specimens regarded as interesting from a taxonomical and/or nomenclatural point of view (isotypes of Silene holzmanii Heldr. ex Boiss. and of Arenaria minutiflora Loscos). Therefore, the main interest of the herbarium lies in the diversity of the geographical provenance of plants, which makes of this collection one of the first"pan-European herbaria" in Catalonia.

ABSTRACT The citriculture consists in several environmental risks, as weather changes and pests, and also consists in considerable financial risk, mainly due to the period ofreturn on the initial investment. This study was motivated by the need to assess the risks of a business activity such as citriculture. Our objective was to build a stochastic simulation model to achieve the economic and financial analysis of an orange producer in the Midwest region of the state of Sao Paulo, under conditions of uncertainty. The parameters used were the Net Present Value (NPV), the Modified Internal Rate of Return(MIRR), and the Discounted Payback. To evaluate the risk conditions we built a probabilistic model of pseudorandom numbers generated with Monte Carlo method. The results showed that the activity analyzed provides a risk of 42.8% to reach a NPV negative; however, the yield assessed by MIRR was 7.7%, higher than the yield from the reapplication of the positive cash flows. The financial investment pays itself after the fourteenth year of activity.

La pedagogia ha tractat la qüestió de gènere i d’educació? I si és el cas, de quina manera? Quins han estat els resultats? Tant el valor de l’educació com el de gènere foren qüestionats i revisats al començament del segle XX. Els resultats d’aquelles reflexions i les batalles lluitades per millorar les condicions, comencen a sentir-se cent anys més tard. Aquest article inclourà primerament una visió general de la situació de la dona en l’educació en l’àmbit mundial. En segon lloc, se centrarà en els enfocaments pedagògics transformacionals que de manera gradual comencen a introduir-se en els sistemes educatius convencionals —també en algunes universitats i programes de traducció—, secundats d’una banda pels principis de democràcia, diàleg, carnaval, experimentació i (socio) constructivisme, i per la neurociència i la psicologia de l’altra. És evident que aquests enfocaments desafien la discriminació i afavoreixen la creació de ponts, no tan sols entre gèneres, sinó també entre etnicitats i classes social

Between the mid-nineteenth century and the outbreak of the Spanish Civil War in 1936, Spain undertook a sustained process of economic growth and structural change, but was unable to converge with the core European economies.1 The reasons behind Spain"s failure to converge have been a subject of debate among historians for decades. 2 This dissertation aims to analyze the role played by infrastructure in Spanish economic growth during that period, and tries to find out to what extent the potential shortage or inadequacy of the Spanish infrastructure endowment was one of the factors to blame for the country"s nonconvergence. The dissertation draws on recent research on the economic impact of infrastructure, and on the numerous attempts to measure that impact which have been undertaken in the wake of David Aschauer"s work on the United States.

A detailed analysis of the morphology and the Holocene seismic and sequence stratigraphy and architecture of the infralittoral sedimentary environment of the El Masnou coast (Catalonia, NW Mediterranean Sea) was carried out using multibeam bathymetry and GeoPulse seismic data. This environment extends down to 26-30 m water depth, and is defined morphologically by two depositional wedges whose seafloor is affected by erosive furrows, slides, fields of large- and small-scale wavy bedforms, and dredging trenches and pits. Erosive terraces are also identified in the transition domain toward the inner continental shelf. The Holocene stratigraphy of the infralittoral environment is defined by two major seismic sequences (lower and upper), each one formed by internal seismic units. The sequences and units are characterised by downlapping surfaces made up of deposits formed by progradation of coastal lithosomes. The stratigraphy and stratal architecture, displaying a retrogradational arrangement with progradational patterns of minor order, were controlled by different sea-level positions. The stratigraphic division represents the coastal response to the last fourth-order transgressive and highstand conditions, modulated by small-scale sea-level oscillations (≈1-2 m) of fith to sixth order. This study also highlights the advantage of an integrated analysis using acoustic/seismic methods for practical assessment of the anthropogenic effects on infralittoral domains based on the association of marine geological observations.

The government of Catalonia has developed a planning framework that seeks to establish the provision of cultural facilities throughout the country. The Cultural Facilities Plan of Catalonia (PECCAT) is based on an analysis of historical gaps and establishes a minimum spatial scheme. The plan responds to problems associated with the absence of a former similar instrument, which has led to an inconsistent and inappropriate cultural infrastructure that fails to fulfill its fundamental mission of securing the cultural rights of the population. The paper sets forth the aims of this policy and describes the objectives and basic characteristics of the plan and the expected outcomes. With the plan, the government of Catalonia seeks to rebalance the infrastructure within the territory and to ensure universal access to basic cultural services, while avoiding a logic of standardization and taking local communities into account. With the development of local plans in the municipalities, local governments encourage community participation processes to adapt and decide on priorities for action based on needs assessments and cultural opportunities for local sustainable development. The local plans focus on local cultural strengths, take advantage of opportunities, and aim to realize the cultural dynamics of a place through establishing an infrastructure that can best respond to the needs and cultural demands of the local communities, taking into account economic, social, and environmental sustainability.

With this paper we build a two-region model where both innovation and imitation are performed. In particular imitation takes the form of technological spillovers that lagging regions may exploit given certain human capital conditions. We show how the high skill content of each region’s workforce (rather than the average human capital stock) is crucial to determine convergence towards the income level of the leader region and to exploit the technological spillovers coming from the frontier. The same applies to bureaucratic/institutional quality which are conductive to higher growth in the long run. We test successfully our theoretical result over Spanish regions for the period between 1960 and 1997. We exploit system GMM estimators which allow us to correctly deal with endogeneity problems and small sample bias.

[eng]A few 16th century coins found in the Cova del Ramal de la Raconada (Castelldefels, Barcelona) This paper announces the finding of eight coins at the excavation site of the Cova del Ramal de la Raconada (Castelldefels, Barcelona). An analysis of the cluster enables this numismatic material to be situated chronologically in the third quarter of the 16th century and to associate it with the monetary circulation at the beginning of the Modern Age. In addition, the material from the Cova del Ramal de la Raconada and other Bajo Llobregat locations enables us to make assumptions on the historical context at the end of the 16th century in the Barcelona coastal region.
