Quantity v/s quality of scientific publications: an analysis for main cities of Spain (2001-2007)

Since the last quarter of the 20th century, most of the world population has experimented an important process of globalization, mainly due to; the accelerated knowledge production, the increase of intangible capital on a macroeconomic scale, the increase in levels of innovation, and the ICT revolution that have democratized access to information and knowledge dissemination. This new economic base, located in cities, is supported on knowledge and information as sources of production and competitiveness. The number of scientific publications on indexed journals is a scale, often used to measure the degree of strength of the scientific sector of a particular place. But this scale ignores the quality of the counted works, i.e. the impact they have generated in the scientific world. This work seeks to highlight the dynamics of scientific production in Spain. Specifically, it aims to analyze the quantity and quality of scientific publications in the period between 2001 and 2007. For this analysis, the quantity is measured by the number of scientific papers published by researchers from a city and the quality by the number of times that works signed by scientists from a city, have been cited by researchers around the world. In this study we establish a bibliometric analysis based on: 1) the number of scientific contributions to municipalities of more than 30,000 people whose information is derived from the SCI-E and 2) the number of citations for the top 10 cities with information derived from Scopus. Finally, we contrast the results of the more representatives cities, with the aim of clarify the relationship between the quantity and quality between quantity and quality of the scientific publication. The results suggest a concentration of quantity and quality of the scientific production in the Spanish metropolitan areas. However, we can provide that ranking who have the main cities in the context of national scientific publication is not similar for both parameters.

Does Bargaining Matter in the Small Firm Matching Model?

In this article, we use a stylized model of the labor market to investigate the effects of three alternative and well-known bargaining solutions. We apply the Nash, the Egalitarian and the Kalai-Smorodinsky bargaining solutions in the small firm’s matching model of unemployment. To the best of our knowledge, this is the first attempt that has been made to implement and systematically compare these solutions in search-matching economies. Our results are twofold. First from the theoretical/methodological viewpoint, we extend a somewhat flexible search-matching economy to alternative bargaining solutions. In particular, we prove that the Egalitarian and the Kalai-Smorodinsky solutions are easily implementable and mathematically tractable within search-matching economies. Second, our results show that even though the traditional results of bargaining theory apply in this context, they are generally qualitatively different and quantitatively weaker than expected. This is of particular relevance in comparison with the results established in the earlier literature.search and matching models, bargaining theory, Nash, Egalitarian, Kalai-Smorodinsky

Excellence and Quality in Andalusia University Library System

From 1996 onwards, then, the Quality Assessment National Plan and the adoption of its agenda by regional authorities and Universities alike has resulted in a growing acceptance by the Spanish academic community of the challenges and opportunities offered by evaluation and quality assurance activities. Academic librarians have been committed to this culture of quality from the very beginnings and in most cases have being leading the way in their own institutions. General tools like the Evaluation Guide referred to above developed to be applied in administration and services alike were of little use for libraries, so academic libraries have been the first units to develop their own evaluation guides at local and regional levels. University System in Andalusia (Spain) is formed by 10 Universities financed by regional government. The Quality Unit of Andalusia Universities convened in 2000 an Assessment University Libraries Pilot Plan to do a global analysis of the Library System. This Pilot Plan has had three steps: - During 2000-2002, a technical committee to draft a new evaluation guide for academic libraries. Based on the EFQM, because of its growing influence in the evaluation of the public sector and not-for-profit organizations across Europe. During the course of our work we were delighted to see that we concurred basically with the approach taken by LISIM. The Guide is divided into 5 parts, as follows: Analysis and Description of 9 criteria adapted to library scenario, 35 Tables for data collection, a set of 30 quality and performance Indicators, a Excellence-rating matrix, an objective tool, to determine the level of excellence achieved by the library on a scale from 0 to 10, and General guidelines for the Assessment Committees of University Departments (the basic unit of research assessment undertaken by the University) and of degree courses (the basic unit of assessment of teaching personnel). - In 2002-2004, a coordination committee drove the assessment process of 9 libraries and tested materials and evaluation methodology. The Pilot Plan has finalised with External Evaluation for 5 External Committee formed by librarians, faculties and EFQM methodology specialist. The aim of this paper is explain different parts and strong points of this process and how EFQM is suitable for all kind of librarie

Arquitectura y transformación en la Ciudad Universitaria de la UNAM en México

[EN] Architecture in permanent transformation is the starting point of this article, focused on the interaction between material and social aspects of a case study on modern Mexican housing, observing the building’s life in relation to its inhabitants. The Multifamily Apartment Building for Teachers (Multifamiliar para maestros), a faculty housing building at the UNAM campus, is a mid-twentieth-century experimental housing project, developed at the beginning of Mexico City´s densification. Today it is registered in UNESCO’s World Heritage Sites. The case study sheds some important insights into the transformations of a spatial modern utopia facing inhabitants' needs. Numerous differences were detected between the original idea behind the building’s architecture and the reality of its users today, revealing not only the ambiguous nature of the building but also problems derived from the country’s accelerated modernization. The results show contrasting approaches of the intermediate space between the building’s conception, and the constant process of becoming a home, where the scope of its habitability is negotiated. [ES] Este texto propone un enfoque que toma la transformación arquitectónica permanente como punto de partida en el estudio de la interacción entre los planos materiales y sociales de la vivienda moderna en México. Al abordar como caso de estudio un edificio significativo en la historia de la vivienda colectiva moderna en México como es el multifamiliar para maestros de la Universidad Nacional Autónoma de México (UNAM). Gracias al contacto con los vecinos, se logró un acceso privilegiado al inmueble diseñado y construido por los arquitectos Mario Pani y Salvador Ortega, lo que permitió realizar un levantamiento, un diagnóstico del estado del edificio y entrevistas a sus habitantes. Se detectaron numerosas contradicciones entre la idea original de edificio y la realidad de los usuarios en la actualidad, lo que arroja luz no solo sobre la naturaleza ambigua del edificio sino también sobre una etapa de modernización acelerada del país y de crecimiento de utopías espaciales como Ciudad Universitaria, catalogada como Patrimonio Mundial de la Humanidad por la UNESCO. El caso de estudio confirma el interés de un enfoque centrado en el espacio intersticial entre la concepción del edificio y los ideales detrás de este y el proceso de devenir hogar, como un espacio donde se negocian constantemente los alcances de la habitabilidad.Leal, A.; Cruz, B.; Pérez-Duarte, A.

Impact of Nutrition on Pulmonary Arterial Hypertension

Pulmonary arterial hypertension (PAH) is characterized by sustained vasoconstriction, vascular remodeling, inflammation, and in situ thrombosis. Although there have been important advances in the knowledge of the pathophysiology of PAH, it remains a debilitating, limiting, and rapidly progressive disease. Vitamin D and iron deficiency are worldwide health problems of pandemic proportions. Notably, these nutritional alterations are largely more prevalent in PAH patients than in the general population and there are several pieces of evidence suggesting that they may trigger or aggravate disease progression. There are also several case reports associating scurvy, due to severe vitamin C deficiency, with PAH. Flavonoids such as quercetin, isoflavonoids such as genistein, and other dietary polyphenols including resveratrol slow the progression of the disease in animal models of PAH. Finally, the role of the gut microbiota and its interplay with the diet, host immune system, and energy metabolism is emerging in multiple cardiovascular diseases. The alteration of the gut microbiota has also been reported in animal models of PAH. It is thus possible that in the near future interventions targeting the nutritional status and the gut dysbiosis will improve the outcome of these patients.This study was supported by grants from Mineco (SAF2016-77222-R and SAF2017-8489-R), with funds from the European Union (Fondo Europeo de Desarrollo Regional FEDER) and Fundación Contra la Hipertensión Pulmonar (Empathy grant)

Data Analysis and Strategies to Overcome the Crisis

UIDB/00417/2020 UIDP/00417/2020The spread of the COVID-19 pandemic worldwide, and the restrictions imposed by the social distance and the enforced confinement, are having an impact on the art markets globally. The aim of this article is to evaluate the impact of an external shock in the primary art market, using three countries as a case study: Portugal, Spain, and Brazil. These geographies have in common being at the margins in the art market’s main art hubs. It is intended to analyze how agents are responding to the new context, according to the data gathered within the gallery sector. The methods applied in the research are a combination of surveys carried out by the authors, field-based observation, along with an academic literature review, complemented by international and national reports analysis. The study’s main findings allow us to characterize the art market as a very resilient sector that energetically responded to the crisis, able to adapt and overcome challenges imposed by the new pandemic situation. Contemporary art galleries expanded digital activities, kept participating in art fairs hybrid models, continued to focus on internationalization, and pointed to the strengthening of public policies towards the sector and partnerships as key strategies to overcome the crisispublishersversionpublishe
