La revista barcelonesa 'El Arte de Curtir' y el quebracho colorado paraguayo: periodismo y economía

[spa]Este trabajo analiza el papel desempeñado por la revista El Arte de Curtir, creada en el año 1909 en la ciudad de Barcelona por los hermanos Pedro Pablo, Fernando y Carlos de Corral y Tomé, cuya Fábrica de Extractos Curtientes dedicada al quebracho colorado paraguayo fue la base de organización del extracto tánico utilizado en Cataluña para la curtición.

Especial Les Rambles

Since we routinely put questions forward for discussion that involve urban planning in Barcelona, let's begin with one that might seem too obvious: What to do about its main street? We solicited the views of 13 professional architects and geographers who have some connection to the Rambla, either because they live or work nearby or once did professionals, in other words, who are intimately familiar with it. The range of their responses surprised us. Issues like making the Rambla car-free or the street's physical design, recurring themes in recent years, here take a back seat. Instead, questions about underlying urban structures and street-level uses come up repeatedly

Les Compravendes al detall i a crèdit en el món artesà: El cas dels especiers i els candelers: El cas dels especiers i els candelers

Estudi de com el crèdit va tenir un paper molt important en les compravendes al detall en els gremis dels especiers (o apotecaris) i cerers a la Barcelona baixmedieval. Es pretén extrapolar les conclusions per aquests dos col•lectius a altres grups socioprofessionals similars. Es parteix de la teoria que aquest paper del crèdit va ser ben diferent que el desenvolupat en les pràctiques mercantils, bancàries i rendistes

Les Ordinacions de mercaderies encamerades o falsificades: evolució del control municipal sobre la qualitat de les espècies i les drogues (segles XIV-XV)

Aproximació al funcionament de la mostassafia barcelonina medieval, i a la creació d’un dret municipal encarregat de regular la vida ciutadana. Aquesta aproximació es fa a partir d’un aspecte relativament simple: el control de la qualitat de les espècies i les drogues. L’anàlisi de les ordinacions de mercaderies encamerades serveix per veure com els consellers aprofitaren la creació de la figura del mostassaf i l’establiment de les seves àmplies atribucions normatives per controlar l’activitat mercantil barcelonina

Ordinacions, privilegis i oficis: la regulació de l'art de l'especieria (s. XIV-XV)

L’estudi de l’evolució de la regulació de l’art de l’especieria o apotecaria a Barcelona permet copsar com les arts i els oficis no solament s’aprofitaren en benefici propi de la cessió del "ius statuendi" al govern municipal, sinó que, quan ho van considerar convenient, van acudir al rei per tal que consolidés per via de privilegi la seva posició de força en el seu camp professional

Um estudo das condições de percolação e estabilidade em barragens de terra mediante métodos geofísicos: caso do dique de Sant Llorenç de Montgai - Espanha

The monitoring of Earth dam makes use of visual inspection and instrumentation to identify and characterize the deterioration that compromises the security of earth dams and associated structures. The visual inspection is subjective and can lead to misinterpretation or omission of important information and, some problems are detected too late. The instrumentation are efficient but certain technical or operational issues can cause restrictions. Thereby, visual inspections and instrumentation can lead to a lack of information. Geophysics offers consolidated, low-cost methods that are non-invasive, non-destructive and low cost. They have a strong potential and can be used assisting instrumentation. In the case that a visual inspection and strumentation does not provide all the necessary information, geophysical methods would provide more complete and relevant information. In order to test these theories, geophysical acquisitions were performed using Georadar (GPR), Electric resistivity, Seismic refraction, and Refraction Microtremor (ReMi) on the dike of the dam in Sant Llorenç de Montgai, located in the province of Lleida, 145 km from Barcelona, Catalonia. The results confirmed that the geophysical methods used each responded satisfactorily to the conditions of the earth dike, the anomalies present and the geological features found, such as alluvium and carbonate and evaporite rocks. It has also been confirmed that these methods, when used in an integrated manner, are able to reduce the ambiguities in individual interpretations. They facilitate improved imaging of the interior dikes and of major geological features, thus inspecting the massif and its foundation. Consequently, the results obtained in this study demonstrated that these geophysical methods are sufficiently effective for inspecting earth dams and they are an important tool in the instrumentation and visual inspection of the security of the dams

From problems to opportunities a shift needed for public health

Public health has in the past been a problem orientated discipline which has devoted its energies mainly to defining, prioritizing and trying to solve problems. This means paying attention to the short-term. If we examine the rises and falls of public health as a discipline with its successes and failures in gaining health, and if we compare public health with successful organisations, the need for changing the emphasis from problems to opportunities becomes apparent. In this endeavour for the future, strategic thinking and policy analysis seem appropriate new tools for public health professionals. The economic crisis and the weakness of the welfare state are presented as major opportunities for public health to achieve health gain in Europe.

MAGGnet: an international network to foster mitigation of agricultural greenhouse gases.

Research networks provide a framework for review, synthesis and systematic testing of theories by multiple scientists across international borders critical for addressing global-scale issues. In 2012, a GHG research network referred to as MAGGnet (Managing Agricultural Greenhouse Gases Network) was established within the Croplands Research Group of the Global Research Alliance on Agricultural Greenhouse Gases (GRA). With involvement from 46 alliance member countries, MAGGnet seeks to provide a platform for the inventory and analysis of agricultural GHG mitigation research throughout the world. To date, metadata from 315 experimental studies in 20 countries have been compiled using a standardized spreadsheet. Most studies were completed (74%) and conducted within a 1-3-year duration (68%). Soil carbon and nitrous oxide emissions were measured in over 80% of the studies. Among plant variables, grain yield was assessed across studies most frequently (56%), followed by stover (35%) and root (9%) biomass. MAGGnet has contributed to modeling efforts and has spurred other research groups in the GRA to collect experimental site metadata using an adapted spreadsheet. With continued growth and investment, MAGGnet will leverage limited-resource investments by any one country to produce an inclusive, globally shared meta-database focused on the science of GHG mitigation.

Testing of stair climbing point-of-choice prompts in Barcelona at an outdoor set of stairs and scalators on the Montjuïc site

Regular stair climbing has well-documented health dividends, such as increased fitness and strength, weight loss and reduced body fat, improved lipid profiles and reduced risk of osteoporosis. The general absence of barriers to participation makes stair climbing an ideal physical activity (PA) for health promotion. Studies in the US and the UK have consistently shown that interventions to increase the accumulation of lifestyle PA by climbing stairs rather than using the escalators are effective. However, there are no previous in Catalonia. This project tested one message for their ability to prompt travelers on the Montjuïc site to choose the stairs rather than the escalator when climbing up the Monjuïc hill. One standard message, " Take the stairs! 7 minutes of stair climbing a day protects your heart" provided a comparison with previous research done in the UK. Translated into Catalan and Spanish, it was presented on a poster positioned at the point of choice between the stairs and the escalator. The study used a quasi-experimental, interrupted time series design. Travelers, during several and specific hours on two days of the week, were coded for stair or escalator use, gender, age, ethnic status, presence of accompanying children or bags by one observer. Overall, the intervention resulted in a 81% increase in stair climbing. In the follow-up period without messages, stair climbing dropped out to baseline levels. This preliminary study showed a significant effect on stair use. However, caution is needed since results are based on a small sample and, only a low percentage of the sample took the stairs at baseline or the intervention phase . Future research on stair use in Catalonia should focus on using bigger samples, different sites (metro stations, airports, shopping centers, etc) , different messages and techniques to promote stair climbing.

Elaboració d'un model d'avaluació dels EAP i la seva aplicació al pla estratègic de l'EAP Sants-Montjuïc de Barcelona. 'Elaboración de un modelo de evaluación de los EAP y su aplicación en el plan estratégico del EAP Sants-Montjuïc de Barcelona'.

Se propone un modelo de evaluación para los EAP (Equipos de Asesoramiento Pedagógico), orientado a su mejora, basado en la autorreflexión colegiada sistemática de sus miembros, validado a partir de la razón dialógica y con una perspectiva holística de la realidad del asesoramiento. La intención es ofrecer un modelo que aporte un conocimiento relevante sobre el trabajo de los EAP más allá de las evaluaciones cuantitativas y de las valoraciones asistemáticas. El modelo incluye dos propuestas de herramientas para ayudar a la autoevaluación: una propuesta de ámbitos de decisión/evaluación para situar las acciones de revisión y mejora y un sistema abierto de criterios de calidad para orientar el trabajo de autoevaluación. Las dos propuestas son abiertas y permiten su adaptación a las características y necesidades de cada equipo. También se hace una recomendación de procedimientos con el fin de desarrollar la evaluación. Las propuestas que configuran el modelo de evaluación se han formulado a partir de una investigación en que se ha consultado a los profesionales que están implicados en la tarea del asesoramiento.
