Competition for long-haul connecting traffic among airports in Europe and the Middle East
2017
Abstract This paper analyzes the competitive position of major hub airports in Europe and the Middle East for long-haul connecting traffic. We apply a connection builder to construct competitive flight connections. A stand out feature of the proposed connection builder is the calibration of the model parameters using booking data, composed of actual passenger demand between a given origin and destination (O&D) market. The methodology is applied to measure competition between hubs using flight schedule data to calculate connectivity measures like the number of city-pairs connected via a hub airport. Our results show that the Middle Eastern hubs have improved their competitive position, while…
Signaling Reduction in 5G eV2X Communications Based on Vehicle Grouping
2019
Groups of users, sometimes referred to as clusters, have been exploited in several works to enhance wireless communications. Leveraging on previous ideas, the main goal of this paper is to take advantage of vehicle grouping in order to reduce uplink signaling in fifth generation (5G) vehicular communications. Several schemes to reduce uplink signaling are proposed and particularized in two specific 5G uses cases: the reporting of Channel Busy Ratio (CBR), and the reporting of beam measurements in beam management procedures. The achieved signaling reduction is analytically evaluated in an example of urban scenario with high vehicle densities for different group sizes. The signaling load can …
Availability, demand, perceived constraints and disuse of ADAS technologies in Spain: findings from a national study
2019
Advanced Driver Assistance Systems (ADAS), created for enhancing the driving experience and actively preventing road crashes, have been progressively incorporated in vehicle designing essentially during the last decade. However, the literature has shown how some of these assisting technologies are not used by drivers in tandem with their potential. The aims of this study were, first, to examine the availability and demand of ADAS technologies among Spanish drivers and, secondly, to explore the perceived constraints and discouraging reasons for avoiding the use of ADAS available in their vehicles. For this national cross-sectional study, data from 1,207 Spanish drivers were analyzed. The res…
Bizet, Bach und Beyoncé. Hochkulturelle Musik in grenzüberschreitenden Geschmackskombinationen
2017
Dieser Beitrag setzt sich mit den musikalischen Korrelaten eines hochkulturellen Musikgeschmacks auseinander. Von besonderem Interesse sind dabei asthetische Grenzuberschreitungen, bei denen Vorlieben fur Opern und klassische Musik beispielsweise mit popularen oder trivialen Praferenzen verbunden werden. Zwei Fragen stehen im Zentrum der Diskussion: Welche Kombinationen hochkulturellen Musikgeschmacks mit anderen musikalischen Praferenzen treten in Deutschland auf und finden sich in verschiedenen Kombinationen auch unterschiedlich starke Zusammenhange mit der sozialen Position? Zur Beantwortung der Fragen wird das Konzept der Omnivorizitat herangezogen, konzeptionell erweitert und empirisch…
A One Health perspective on the issue of the antibiotic resistance
2020
For a few years now, the One Health concept has appeared to go hand in hand with the issue of antibiotic resistance as the most comprehensive and global solution. As part of a study comparing the publicization process of the links between antibiotic resistance and food in France and in the United States, this paper retraces the One Health concept's trajectory in terms of significations and (re)definitions, according to the actors adopting this approach as a viable solution. Furthermore, this paper questions the concept's take over impact in antibiotic resistance reframing as well as its expansion in terms of functioning and applicability. Within social sciences research, interest in the iss…
Mass data gathering and surveillance: the fight against facial recognition technology in the globalized world
2020
The growing use of facial recognition technologies has put them under the regulatory spotlight all around the world. The EU considers to regulate facial regulation technologies as a part of initiative of creating ethical and legal framework for trustworthy artificial intelligence. These technologies are attracting attention of the EU data protection authorities, e.g. in Sweden and the UK. In May, San Francisco was the first city in the US to ban police and other government agencies from using facial recognition technology, soon followed by other US cities. The paper aims to analyze the impact of facial recognition technology on the fundamental rights and values as well as the development of…
Communication Practices and Social Tie Formation: A Case Study of Recreational Lifestyle Sports Cultures
2017
This case study examines contemporary recreational sports practitioners’ communication practices and social tie formation from the perspective of two lifestyle sports disciplines: climbing and trail running. Online survey results from 301 climbers and trail runners from Finland indicate that computer-mediated communication (CMC) has established its place in recreational lifestyle sports cultures; however, it has not done it at the expense of face-to-face (FtF) communication. Online interaction produces weak social ties with instrumental and informative value, but physical location is essential in establishing ties with emotional and appraisal value. This paper argues that it is the sports s…
Back to the roots?! Der datengestützte Tür-zu-Tür-Wahlkampf in politischen Wahlkampagnen
2018
Trotz der mannigfaltigen Moglichkeiten, die soziale Online-Netzwerke und klassische Massenmedien zur Wahleransprache bieten, greifen jungste Kampagnen auf ein Wahlkampfinstrument zuruck, das vor allem in vormodernen Wahlkampfen zum Einsatz kam und auf den direkten interpersonellen Dialog mit den Burgern setzt: den Tur-zu-Tur-Wahlkampf. Als Symbiose aus datengestutzter Targeting-Technik, technologischer Infrastruktur und direkter interpersoneller Wahleransprache lasst sich die ‚Renaissance‘ dieses scheinbar antiquierten Wahlkampfinstruments durch gesellschaftliche Wandlungsprozesse und durch Entwicklungen im Bereich der Informations- und Kommunikationstechnologien erklaren. Auf Basis der int…

LA TRANSMISIÓN DIGITAL DE LAS AGENDAS POLÍTICAS EN LAS ELECCIONES LOCALES DE 2015 DE LA CIUDAD DE VALENCIA
2020
El objetivo de la investigación es el estudio de la composición de las agendas temáticas partidistas en la campaña de las Elecciones Locales de 2015 en la ciudad de Valencia, así como de su transmisión en Internet a través de los sitios web de campaña, de las cuentas en Twitter de partidos y candidatos y de las piezas periodísticas publicadas en los cibermedios con cobertura informativa municipal. El trabajo constata que las formaciones construyeron sus agendas oficiales a partir, sobre todo, de asuntos relacionados con la política sectorial. Partidos y candidatos redefinieron sus agendas en Twitter y utilizaron la red de microblogging de manera instrumental, para la difusión de sus mensaje…
