Twenty Years of Airport Efficiency – A Bibliometric Analysis

This paper analyses the scientific study on airport efficiency in the WoS (Web of Science) database for the period 2000–2019. Productivity indicators have been obtained by author, years, journals, and institutions, and an analysis of visibility, impact, and scientific collaboration through co-citations was performed. The areas of greatest application are transport, engineering, and economics. This study reveals the existence of three research lines, one on airport safety and management, another on technical efficiency using mainly the DEA method, and the third associated with airport regularization issues. An important issue which is increasingly taken into account in efficiency studies is related to environmental aspects. In the ranking of journals publishing on airport efficiency, ordered by number of articles indexed in WoS, Journal of Air Transport Management is the one with the highest number of cited articles and publications, whereas Sustainability stands out as the first non-specific journal on transport. The University of Lisbon and the University of British Columbia are the ones that deal most with airport efficiency

Situation of European airlines caused by COVID-19: restrictions, government subsidies and future prospects

The COVID-19 pandemic has been an unprecedented crisis, severely affecting the economy and many sectors, including the airline industry. This paper reviews this situation to see how airlines have acted since the beginning of COVID-19. The airline industry is dependent on financial support and subsidies to cope with the massive drop in air travel due to the coronavirus. The support received by the major airlines has been examined. In addition, a comparison has been made of all the aviation restrictions that have been implemented by different European governments. Travellers from countries with a higher incidence of cases, or with a growing rate of cases, have the most restrictions on travel to other countries. Furthermore, the strategies and protocols being implemented by certain airlines following the lifting of some of the restrictions on passenger air traffic are analysed. This paper will provide an insight into how airlines are coping with this unfavourable environment, as well as some of the future prospects and strategies of the aviation sector

Predicció de mutacions a partir de la descomposició per residus de l'energia d'unió proteïna-pèptid

En aquest projecte estudiem un cas a partir d'unes dades reals per tal de predir mutacions. A partir de les observacions i resultats obtinguts en aquest estudi, s'ha desenvolupat una aplicació interactiva generalitzada per a poder automatitzar certes tasques i facilitar l'estudi d'altres casos.In this project we study a case study based on some real data to predict mutations. Based on observations and results obtained in this study, we have developed a generalized interactive application to automate certain tasks and facilitate the study of other cases

Unidad de acción. Un principio, no una opción

El objetivo principal de este trabajo es evaluar, en un contexto de estudio prospectivo sobre desarrollos futuros de la estrategia española de seguridad, las principales características que tiene, o debería tener, el vector definido por la Unidad de Acción del Estado. Para ello se toma como referencia la posición fijada en este concepto por la Estrategia de Seguridad Nacional de 2013. Partiendo de este documento se realiza una evaluación sobre la situación actual de los principales factores que le afectan, así como una sucinta visión retrospectiva que intenta ayudar a comprender nuestra realidad en estos asuntos a partir de la evolución de nuestro modelo de organización de Estado. Parte del análisis realizado se sustenta en un recorrido ilustrativo y posiblemente representativo, por un conjunto de sectores de la administración, de cierta conexión con la seguridad nacional, que permite visualizar la posible dificultad sistémica de nuestra administración para la Unidad de Acción, al tiempo que explorar algunas líneas de trabajo que permitan avanzar positivamente hacia el futuro
