    Get PDF
    Para una transición sostenible es relevante analizar las percepciones de las poblaciones, ya que su concienciación afecta directamente a la eficacia de las medidas y políticas aplicadas. Para ello, se ha tomado como base la séptima olea de World Values Survey (2017-2022), que pone a los encuestados ante la disyuntiva de tener que elegir si la máxima prioridad debe ser la protección del medio ambiente o el crecimiento económico. En primer lugar, se analizan las respuestas a nivel mundial y, a continuación, se restringe la base de datos a las respuestas de China, Estados Unidos y Alemania. Esto proporciona una visión más detallada de los factores que pueden influir en la priorización de la protección del medio ambiente sobre el crecimiento económico para cada individuo. La regresión logística binaria revela que existen diferencias entre las respuestas de los tres países. Dependiendo del país, los factores que afectan positiva o negativamente varían significativamente, pero los tres coinciden en que el nivel de educación afecta positivamente a que las personas prioricen la protección de medio ambiente.For a sustainable transition, it is relevant to analyse the perceptions of the population, as their awareness directly affects the effectiveness of the measures and policies implemented. To this end, the seventh wave of the World Values Survey (2017-2022) has been taken as a basis, which puts respondents at the dilemma of having to choose whether environmental protection or economic growth should be the top priority. First, the responses are analysed globally and then the database is limited in responses from China, the United States, and Germany. This provides a more detail vision of which factors may influence the prioritization of environmental protection over economic growth for each individual. Binary logistic regression reveals that there are differences between the responses of the three countries. Depending on the country, the factors that affect positively or negatively vary significantly, but all three countries agree that the level of education positively influences on priority people give to environment.Graduado o Graduada en Administración y Dirección de Empresas por la Universidad Pública de Navarra (Programa Internacional)Enpresen Administrazio eta Zuzendaritzan Graduatua Nafarroako Unibertsitate Publikoan (Nazioarteko Programa

    Actualmente, el sistema sanitario español está colapsado y se producen diariamente largas listas de espera en los centros de atención primaria. Este problema se ha visto intensificado con la pandemia Covid-19, que ha revelado a las grandes masas las carencias de nuestro sistema sanitario. Los médicos se ven obligados a aumentar el cupo de pacientes que visitan en un día para dar abasto, lo que acaba afectando tanto a la calidad de la visita del paciente como a su propia salud mental. En la aplicación web que se desarrollará en este proyecto, se implementarán una serie de funcionalidades diseñadas para solucionar algunos de los problemas que padece el actual programa sanitario de atención primaria de Cataluña. Estas funcionalidades tendrán como objetivo principal reducir el tiempo que el personal sanitario invierte introduciendo o buscando información en el sistema.Nowadays, the Spanish health system is collapsed and there are long waiting lists in primary care centers everyday. This problem has intensified with the Covid-19 pandemic, which has revealed to the people the shortcomings of our health system. Doctors are forced to increase the number of patients they visit in a day to cope, which ends up affecting both the quality of the patient's visit and their own mental health. In the web application that will be developed in this project, it will be implemented some functionalities designed to solve the problems suffered by the current primary care health application in Catalonia. The main objective of these functionalities will be to reduce the time that healthcare staff spend entering or searching for information in the system

    El gran número de imágenes marianas que ofrecen su patronazgo a distintas localidades españolas remontan sus orígenes a la Edad Media, aunque su culto tomó aún más fuerza durante la Edad Moderna. En este estudio he analizado la obra del jesuita del siglo XVIII Juan de Villafañe y gracias a él estudiaremos las principales características comunes para buena parte de las advocaciones marianas españolas durante la modernidad: desde las leyendas sobre su aparición hasta sus milagros y la construcción de las ermitas.The origins of the great number of Marian images that offer their patronage to different Spanish towns goes back to the middle ages, although its cult became stronger during modern times. In this essay I have analysed Juan de Villafañe’s work, from the eighteenth century, thanks to that work we will study the main characteristics common to most of the Marian advocations in Spain: from the legends about their apparition to their miracles and the building of their hermitages.Departamento de Historia Moderna, Contemporánea y de América, Periodismo y Comunicación Audiovisual y PublicidadGrado en Histori

    Music as soft power: the electoral use of spotify

    Get PDF
    The changes brought by new technologies and the ensuing rapid development of the communication field have resulted in an increasing number of studies on politicians’ use of the internet and social media. However, while election campaigns have been the predominant research area in political communication scholarship, music has not yet been taken as an object of study alongside spectacularisation and politainment. Aside from some preliminary studies, systematic research on music in politics is scarce. The literature holds that music is a universal language. Music in politics can therefore be deemed to be an identification tool that can help politicians connect with voters and bring together positions between the different actors of international relations. This is an exploratory study about the use of music in political campaigning. It is focused on the role played by the Spotify playlists created by the main political parties in recent election campaigns in Spain. The initial hypothesis is that some of the candidates strategically selected songs to be shared with their followers. A quantitative content analysis (N = 400) of some Spotify playlists showed that there were significant differences in the selection of songs among the different political parties. This research contributes to the understanding of how Spotify has been used for electoral campaigning, as well as shedding some light on the current communication literature on music and politics

    Los trabajos previos en los que se han estudiado las recomendaciones de metionina+cistina para gallinas ponedoras son muy numerosos, pero los resultados obtenidos presentan una gran variabilidad y, en algunos casos, son contradictorios. Esta variabilidad se explica por las condiciones en las que se ha realizado el estudio, la edad de las gallinas, la genética y el parámetro a optimizar. En este sentido, Novak et al. (2004) observaron que las necesidades totales de metionina+cistina eran mayores para maximizar el peso del huevo que para optimizar la producción de huevos o la eficacia alimenticia. Estas diferencias fueron menos importantes entre las 20 y 43 semanas (8%), que de las 44 a las 63 semanas de edad (16%). Además, las recomendaciones para optimizar la producción y el peso del huevo fueron un 17% y 11% mayores, respectivamente, en el primer periodo con respecto al segundo. Por el contrario, Waldroup y Hellwig (1995) encontraron que las necesidades totales de metionina+cistina para optimizar la producción y masa de huevo fueron más elevadas (12 y 10%, respectivamente) de 51 a 71 semanas de edad que de 25 a 45. Cuando las recomendaciones se expresan en unidades digestibles, el rango de necesidades de metionina+cistina digestibles con respecto a lisina digestible varía desde un 81 a un 107% (81%: Coon and Zhang, 1999; 90%: FEDNA, 2008; 91%: Rostagno et al., 2005; 93%: CVB, 1996; 94%: Bregendahl et al., 2008; 99%: Brumano et al., 2010a; 100%: Cupertino et al., 2009; Brumano et al., 2010a; 101%: Brumano et al., 2010b; 107%: Schmidt et al., 2009). Como consecuencia de esta alta variabilidad, es necesario seguir investigando sobre cuál sería el ratio óptimo metionina+cistina/lisina digestible para optimizar los rendimientos de gallinas ponedoras. Por tanto, el objetivo de este trabajo es determinar las necesidades óptimas de metionina+cistina digestibles con respecto a lisina digestible de gallinas Isa Brown desde las 34 a las 42 semanas de eda

    Objective: To evaluate the influence of respiratory allergy on obstetrics and perinatal outcomes. Methods: A nested case–control retrospective study on 41 035 pregnant women. Obstetrics and perinatal outcomes of women with or without respiratory allergy were compared. Rates of preterm delivery (<37 weeks of gestation), low birth weight (<2500 g), neonatal acidosis (pH < 7.20), low 5-min APGAR score (<7), cesarean section rate and indications, and perinatal morbidity and mortality were analyzed. Results are expressed as number and percentages. χ2 and Fisher exact tests were used for comparisons. Logistic regression was used. Statistical significance was set at 95% level (P < 0.05). Results: A total of 724 (1.8%) patients had respiratory allergy, and their rates of preterm delivery and low birth weight were significantly higher than those of control women (both P < 0.001). Nevertheless, analyzing the causes, multiple gestation rate was significantly higher in this group, and adjusting by this, no statistical difference was found in any of the perinatal outcomes studied. In addition, in vitro fertilization and sterility were also significantly higher in the respiratory allergy group (both P < 0.001). Conclusion: Women with respiratory allergy are at higher risks of prematurity and low birth weight but these results are mediated by sterility, in vitro fertilization, and multiple gestation rate. Nonetheless, participation of inflammatory mechanisms should be further studiedThis study did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sector

    Impact of Early Non-Invasive Ventilation in Amyotrophic Lateral Sclerosis: A multicenter Randomized Controlled Trial

    Full text link
    Background and objective: Forced vital capacity (FVC) less than 50% of predicted is one of the main parameters used for Non-Invasive Ventilation (NIV) initiation in Amyotrophic Lateral Sclerosis (ALS). Recent studies suggest that higher values of FVC could be considered as a threshold. The aim of this study is to evaluate whether early use of NIV improves the prognosis of ALS patients compared with standard initiation. Methods: This is a randomized, parallel, multicenter, open-label, controlled clinical trial, with recruitment at the ALS outpatient multidisciplinary units of six Spanish hospitals. Patients were included when their FVC reached the 75% threshold and were randomized by computer, stratifying by center in an allocation ratio of 1:1 to Early NIV (FVC below 75%) or Standard NIV (FVC below 50%) initiation. The primary outcome was time to death or tracheostomy. Trial registration number ClinicalTrials.gov: NCT01641965. Results: Between May 2012 and June 2014, 42 patients were randomized to two groups, 20 to Early NIV and 22 to Standard NIV initiation. We found differences in survival in favor of the intervention group: an incidence of mortality (2.68 [1.87-5.50] vs. 3.33 [1.34-4.80] person-months) and a median survival (25.2 vs. 19.4 months), although without reaching statistical significance (p = 0.267). Conclusions: This trial did not reach the primary endpoint of survival; nevertheless, it is the first Randomized Controlled Trial (RCT) to demonstrate the benefits of early NIV in slowing the decline of respiratory muscle strength and reducing adverse events. Although not all the results reached statistical significance, all the analyzed data favor early NIV. In addition, this study demonstrates good tolerance and compliance with early NIV without quality of sleep impairment. These data reinforce the early respiratory evaluation of ALS patients and NIV initiation with an FVC of around 75%

    N-ACETYLCYSTEINE DOES NOT IMPROVE SPERM MOTILITY OF LIDIA BULL AFTER PROLONGED EPIDIDYMAL STORAGE / LA N-ACETILCISTEINA NO MEJORA LA MOTILIDAD ESPERMÁTICA EN TOROS DE LIDIA LUEGO DEL ALMACENAMIENTO EPIDIDIMARIO PROLONGADO

    The Lidia bovine breed is considered a hallmark of Spanish cattle industry. Assisted reproductive techniques like cryopreservation of epididymal spermatozoa could be considered as an important tool to obtain more offspring and store its genetics. As these bulls are not selected by their reproductive performance or sperm freezability, the quality of their ejaculates is poor and addition of antioxidants prior cryopreservation could exert beneficial effects on the post-thaw sperm quality. The aim of this study was to evaluate the effect of the supplementing a tris-fructose-egg yolk based freezing extender with1 mMand2.5 mMof N-acetylcysteine to sperm recovered from epididymis stored at4ºCfor 24, 48, 72 or 96 hours prior cryopreservation. Motility values and sperm kinematic parameters were compared against control (epididymis stored for 24 hours and no antioxidant addition). Our results showed that N-acetylcysteine addition did not improve sperm motility parameters at any of the time points or dosages tested. In addition, storage of bullfight epididymis up to 96 hours did not significantly affect sperm kinematic parameters or total and progressive motility.RESUMENLa raza de Lidia es considerada una insignia de la industria ganadera española. Las tecnologías de reproducción asistida como la criopreservación de espermatozoides epididimarios podría ser considerara como una herramienta importante para obtener más crías y conservar su genética. Ya que estos toros no son seleccionados por su desempeño reproductivo o congelabilidad espermática, la calidad de sus eyaculados es pobre y la adición de antioxidantes antes de la criopreservación podría tener efectos beneficiosos sobre la calidad del semen descongelado. El propósito de este estudio fue evaluar el efecto de la suplementación del medio a base de tris-fructosa y yema de huevo con 1 mM y 2,5 mM de N-acetilcisteína a espermatozoides recuperados de epidídimos almacenados a 4°C por 24, 48, 72 o 96 horas antes de la criopreservación. Los valores de movilidad y los parámetros de cinética espermática fueron comparados con el control (epidídimos almacenados por 24 horas y sin la adición de antioxidantes). Nuestros resultados muestran que la adición de N-acetilcisteína no mejora los parámetros de motilidad espermática en ninguno de los momentos o dosis evaluadas. Además, el almacenamiento de epidídimos refrigerados hasta 96 horas no afecta significativamente los parámetros de cinética espermática o la movilidad total o progresiva.
