    Este trabajo proporciona una visión acerca del posicionamiento relativo de los distintos sectores de actividad ante los principales retos que afronta la economía española. Por un lado, ante el desafío de impulsar el crecimiento a medio plazo, se examinan las perspectivas de evolución de la productividad por ramas, analizando el capital humano y tecnológico y las dinámicas empresariales dentro de cada sector. Por otro lado, se clasifican los sectores según la resiliencia frente a las diferentes transformaciones estructurales que han de afrontar las principales economías, como la tecnológica y digital, la transición energética y el envejecimiento poblacional. Para ello, se ha resumido la información procedente de un conjunto muy amplio de indicadores sectoriales, lo que permite clasificar las ramas productivas según el grado relativo de exposición frente a cada uno de estos retos. Los servicios de actividades profesionales, científicas y técnicas, información y comunicaciones, y actividades financieras y de seguros, así como la fabricación de maquinaria, productos informáticos, electrónicos y ópticos y la de productos farmacéuticos, se encuentran bien posicionados en términos tanto de productividad como de resiliencia, pero se trata de sectores, en general, con una reducida dimensión en la economía española. Por el contrario, la hostelería, el sector primario y los servicios de transporte presentan las mayores vulnerabilidades en las dimensiones analizadas.This paper studies the relative position of various sectors of activity in the face of the main structural challenges for the Spanish economy. First, as regards the challenge of boosting medium-term growth, we review the sectoral developments on the productivity side, analysing human and technological capital and business dynamics within each sector. Second, the sectors are classified on the basis of their resilience to the different structural transformations currently in the pipeline for the main economies, such as technological and digital transformation, energy transition and population ageing. To this end, the information from a very broad set of sectoral indicators has been summarised in a narrow set of composite indicators in order to classify the productive sectors according to the relative degree of exposure to each of these challenges. Our results show that services relating to professional, scientific and technical activities, information and communication, and financial and insurance activities, as well as the manufacture of machinery, computer, electronics and pharmaceutical products, are well placed in terms of both productivity and resilience. However, in general these sectors have little weight in the Spanish economy. By contrast, accommodation and food service activities, the primary sector and transport services are the most vulnerable in the dimensions analysed

On the one hand, regarding obstacles for boosting medium-term growth, the prospects for the evolution of total productivity are examined by analyzing human and technological capital and business dynamics within each sector. On the other hand, the sectors are classified according to their resilience to the different structural transformations that are currently in the pipeline, such as technological and digital changes, the climate-related energy transition and population ageing. To this end, the information from a broad set of sectoral indicators has been summarized into a narrow set of composite indicators to classify the productive branches according to the relative degree of exposure to each of these challenges. Our results show that professional, scientific and technical activities, information and communications, and financial and insurance services, as well as the manufacture of machinery, computer, electronic and optical products and that of pharmaceutical products are well positioned in terms of both productivity and resilience indicators. However, all these sectors have a relatively small weight in the Spanish economy, in particular, when compared with other advanced economies. On the contrary, the accommodation and food service activities, the primary sector and transport services present the worst overall performance in the dimensions analyzed

    The impact of population ageing on the labour force participation rate in Spain

    Get PDF
    Rationale Population ageing is one of the greatest structural challenges facing the Spanish economy. Foremost among its multiple effects is its contractionary impact on labour supply, which will foreseeably have major implications on both the functioning of the labour market and the potential growth or sustainability of public finances. Takeaways •Population ageing over the past decade has had an estimated negative impact of around 3.4 percentage points (pp) on Spain’s participation rate in 2022. This impact has been uneven by regions, with a sharper fall in the Cantabrian regions (Asturias, Cantabria and the Basque Country). •According to the latest National Statistics Institute’s population projections, the participation rate is set to drop a further 2.8 pp by 2030 owing to the continuing ageing process. Excluding the support of net immigration flows, the drop would be 1.6 pp greater. •In addition, the impact of ageing may deepen regional divergences, since the regions that have an older population and lower GDP per capita may be expected to experience the sharpest falls in the participation rate

    Sarcopenia: Molecular Pathways and Potential Targets for Intervention

    Get PDF
    Aging is associated with sarcopenia. The loss of strength results in decreased muscle mass and motor function. This process accelerates the progressive muscle deterioration observed in older adults, favoring the presence of debilitating pathologies. In addition, sarcopenia leads to a decrease in quality of life, significantly affecting self-sufficiency. Altogether, these results in an increase in economic resources from the National Health Systems devoted to mitigating this problem in the elderly, particularly in developed countries. Different etiological determinants are involved in the progression of the disease, including: neurological factors, endocrine alterations, as well as nutritional and lifestyle changes related to the adoption of more sedentary habits. Molecular and cellular mechanisms have not been clearly characterized, resulting in the absence of an effective treatment for sarcopenia. Nevertheless, physical activity seems to be the sole strategy to delay sarcopenia and its symptoms. The present review intends to bring together the data explaining how physical activity modulates at a molecular and cellular level all factors that predispose or favor the progression of this deteriorating pathology.This study was supported by ISABIAL (grant number 190290) and the Official Funding Agency for Biomedical Research of the Spanish Government, Institute of Health Carlos III (ISCIII) through CIBEROBN (CB12/03/30038), which is co-funded by the European Regional Development Fund

    Background: Early diagnosis of SARS-CoV-2 infection is essential to reduce disease spread. Rapid antigen tests have not been sufficiently evaluated in asymptomatic patients to be used as massive population screening tools. Methods: Head-to-head evaluation of Roche SARS-CoV-2 Rapid Antigen Test and real-time reverse transcription polymerase chain reaction (RT-PCR) as SARS-CoV-2 screening tools performed in asymptomatic adults from a semi-closed community in University of Navarra (Spain) from November 2020 to January 2021. Sensitivity, specificity and predictive values were calculated using RT-PCR as reference method. Findings: Roche SARS-CoV-2 Rapid Antigen Test was performed on 2542 asymptomatic adults in a community with a SARS-CoV-2 incidence of 1·93%. It showed a sensitivity of 71·43% (CI 95%: 56·74 – 83·42) and a specificity of 99·68% (CI 95%: 99·37 - 99·86). Positive Predictive Value was 81·4 (CI 95% 66·6 – 91·61) and Negative Predictive Value was 99·44 (CI 95% 99·06 – 99·69). Test sensitivity was related to viral load, with higher sensitivity in RT-PCR cycle threshold (Ct) values under 25 (93·75%, CI 95%: 71·96 – 98·93), that dropped to 29·41% (CI 95%: 10·31- 55·96) in RT-PCR Ct values above 25. Interpretation: This study suggests that rapid antigen tests are less effective in asymptomatic population, when compared with RT-PCR. Further studies are needed to evaluate different options to improve screenings based on rapid antigen test, such as the use of clinical questionnaires to select higher risk-participants, the confirmation of negative results with RT-PCR or the use of repetitive sequential testing

    Performance Study of Software AER-Based Convolutions on a Parallel Supercomputer

    This paper is based on the simulation of a convolution model for bioinspired neuromorphic systems using the Address-Event-Representation (AER) philosophy and implemented in the supercomputer CRS of the University of Cadiz (UCA). In this work we improve the runtime of the simulation, by dividing an image into smaller parts before AER convolution and running each operation in a node of the cluster. This research involves a test cases design in which the optimal parameters are set to run the AER convolution in parallel processors. These cases consist on running the convolution taking an image divided in different number of parts, applying to each part a Sobel filter for edge detection, and based on the AER-TOOL simulator. Execution times are compared for all cases and the optimal configuration of the system is discussed. In general, CRS obtain better performances when the image is divided than for the whole image.Ministerio de Ciencia e Innovación TEC2009-10639-C04-0
